DOCUMENTS INCORPORATED BY REFERENCE

Portions of the registrant’s definitive proxy statement, which will be issued in connection with the 2021 Annual Meeting of Shareholders of II-VI Incorporated, are incorporated by reference into Part III of this Annual Report on Form 10-K.

Forward-Looking Statements

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 2022 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. We caution you not to rely on them unduly.

II-VI Incorporated does communicate with securities analysts from time to time and those communications are conducted in accordance with applicable securities laws. Investors should not assume that II-VI Incorporated agrees with any statement or report issued by any analyst, irrespective of the content of the statement or report.

II-VI leverages these capabilities to deliver miniature to large-scale precision optical assemblies, including those in combination with thermal-management components, integrated electronics, and software.

II-VI also offers a broad portfolio of compound semiconductor lasers that are used in a variety of applications in our end markets. These lasers enable optical signal transmission, reception, and amplification in terrestrial and submarine communications networks; high-bit-rate server connectivity between and within datacenters; optical communications network monitoring; materials processing; and fast and accurate measurements in biomedical instruments and consumer electronics.

II-VI continues to improve its operational capabilities, develop next-generation products, and invest in new technology platforms to drive growth in the short term and the long term. With our strategic focus on fast-growing and sustainable markets, II-VI pursues its mission of enabling the world to be safer, healthier, closer, and more efficient, and strives to attain its vision of a world transformed through innovative materials vital to a better life today and the sustainability of future generations.

Information Regarding Market Segments and Foreign Operations

7

Financial data regarding our revenues, results of operations, industry segments, and international sales for the three years ended June 30, 2021, are set forth in the Consolidated Statements of Earnings (Loss) and in Note 15. Segment and Geographic Reporting to our Consolidated Financial Statements, which are included in Item 8 of this Annual Report on Form 10-K and are incorporated herein by reference. We also discuss certain Risk Factors set forth in Item 1A – Risk Factors of this Annual Report on Form 10-K related to our foreign operations, which are incorporated herein by reference.

Bookings and Backlog

We define our bookings as customer orders received that are expected to be converted to revenues over the next 12 months. The Company reports as bookings only those orders that are expected to be converted into revenues within 12 months from the end of the reporting period. Bookings are adjusted if changes in customer demands or production schedules cause the expected time of a delivery to extend beyond 12 months. For the fiscal year ended June 30, 2021, our bookings were approximately $3.3 billion, compared with bookings of approximately $2.7 billion for the fiscal year ended June 30, 2020.

We define our backlog as bookings that have not been converted to revenues by the end of the reporting period. As of June 30, 2021, our backlog was approximately $1,252 million, compared with approximately $957 million as of June 30, 2020.

Global Operations

II-VI is headquartered in Saxonburg, Pennsylvania, U.S.A., with RD&E, manufacturing, and sales facilities worldwide. Our U.S. production and RD&E operations are located in Arizona, California, Colorado, Connecticut, Delaware, Florida, Illinois, Massachusetts, Michigan, Mississippi, New Jersey, New York, Ohio, Oregon, Pennsylvania, and Texas, and our non-U.S. production and RD&E operations are based in Australia, China, Germany, Malaysia, the Philippines, Singapore, Sweden, Switzerland, Thailand, the United Kingdom, and Vietnam. We also utilize contract manufacturers and strategic suppliers. In addition to sales offices co-located at most of our manufacturing sites, we have sales and marketing subsidiaries in Belgium, Canada, China, Germany, Hong Kong, Italy, Japan, South Korea, Switzerland, Taiwan, and the United Kingdom.

Human Capital

Our mission is “Enabling the world to be safer, healthier, closer, and more efficient.”

Our vision is “A world transformed through innovative materials vital to a better life today and the sustainability of future generations.”

Our core values are: Integrity, Collaboration, Accountability, Respect, and Enthusiasm (I CARE).

Our people are essential to fulfilling our mission and working toward our vision. As a result, our human capital strategies are core to the long-term success of the Company.

As of June 30, 2021, the Company employed approximately 23,000 employees worldwide.

	Number of employees	Percent of total
Direct production	15,833	69%
Research, development, engineering, sales and marketing	4,276	19%
General administration	2,852	12%
Total:	22,961	100%

We believe that our efforts in managing our workforce have been effective, as evidenced by a strong culture and a good relationship between the Company and our employees.

•Our People. Our people are critical to our continued success. We provide a workplace that develops, supports, and motivates our employees. In FY21, we again participated in the Gallup Employee Engagement Survey. We believe Gallup’s employee engagement survey questions and resources are an effective way to gauge our progress to create a stronger, more engaged workplace. Gallup provides comparative data from numerous studies over many years linked to organizational performance, proven consistent survey methodology, and actionable guidance at both the local and enterprise level. We had a 94% participation rate and an engagement mean of 4.16 out of 5.00. The responses to each of

8

the 12 questions within Gallup’s survey demonstrated improvement by us from our prior survey conducted in FY19. Action plans are created across the globe to continue to improve our engagement level.

•Employee Safety. It is our highest priority to keep our employees, customers, and suppliers safe, as the health and safety of our workforce is fundamental to the success of our business. We provide our employees upfront and ongoing safety training to ensure that safety policies and procedures are effectively communicated and implemented. We have experienced employees on-site at each of our manufacturing locations who are tasked with environmental, health, and personal safety education and compliance. The safety calculation recognized by the Occupational Safety and Health Administration, the Total Recordable Incident Rate (“TRIR”), is closely monitored throughout the Company. As of June 30, 2021, our TRIR was 0.23 as compared to 0.26 for FY20. Each year, we strive to improve our TRIR as a part of our strong safety culture, as evidenced by a year-over-year reduction of 12%. We customize our policies to the local requirements and circumstances of each plant.

•COVID-19. Our top priority during the ongoing COVID-19 pandemic has been and continues to be protecting the health and safety of our employees and their families, our customers, and our communities. Our on-site work environments were changed to accommodate best-in-class protocols. The commitment to this effort is evidenced by the extensive planning and numerous actions we swiftly took to respond to the pandemic, including the development and implementation of a Pandemic Response Team and Pandemic Response Guide, a work-from-home program, health check protocols, temperature screenings, and periodic COVID-19 testing where permitted and deemed appropriate for all employees working on-site. Additionally, new process workflows were initiated to ensure reduced contact for employees working on-site, contact tracing processes and protocols were established, quarantining and testing protocols for exposure and positive tests were implemented, travel guidelines and protocols were created to ensure that employees who must travel for work can do so safely, and phased return-to-work plans and approval processes were formed to enable non-manufacturing employees to return to work when permitted by local government regulations and deemed appropriate by II-VI leadership. We hired an infectious disease expert who specializes in COVID-19 to offer guidance to our Pandemic Response Team, managers, and site leaders. We are continuing with our work-from-home arrangements for non-manufacturing and operations employees through at least December 2021.

•Talent Acquisition, Development, and Training. Hiring talented individuals and continuing to develop them are critical to our operations, and we are focused on creating experiences and programs that foster growth and performance. We have a robust succession-planning process that identifies internal candidates for development. We provide all employees the chance to learn and develop critical skills, and we strive to attract, motivate, and retain high-quality talent. We encourage all employees to broaden their knowledge. For example, we offer monthly Technology Spotlight Seminars designed to highlight and communicate the many technical advances and competencies within II-VI, as well as foster innovation within the Company and technical community. Tuition reimbursement and funding for growth and development is built into the annual budget to ensure that II-VI has the skilled workforce we need. Our global internship programs welcome a new talent pipeline. In FY21, II-VI pledged $1,000,000 to fund STEM educational and research programs in 2021.

•Total Rewards. Our “One II-VI” approach to total rewards provides a competitive total compensation package that: attracts, motivates, and retains high-quality talent; matches total rewards of competitors with which we compete for talent; increases transparency of rewards programs, company and segment metrics, and measurement of achievements in relation to challenging objectives; balances fixed costs (benefits and base pay) and variable costs (bonus and equity), with a substantial portion of total direct compensation tied to performance; pays for performance – base, bonus, and equity reflect both company and individual performance; and aligns with the interests of our shareholders. Globally, all non-sales employees participate in a variable incentive program measured on the operating earnings of their business segment. Similarly, sales employees are incentivized on revenue and profit-after-tax attainment. Select employees are eligible to receive equity-based awards, to align employee and shareholder interests. In addition to offering competitive and fair compensation, we also offer a suite of benefits, including comprehensive health benefits to all of our employees globally.

•Diversity and Inclusion. II-VI supports fundamental human rights – values inherent to all human beings. We expect all leaders and employees to treat each other with dignity, fairness, and respect. We are consciously expanding the diversity of our workforce, creating growth and development opportunities for our employees, embracing different perspectives, and fostering an inclusive work environment. In FY21, we greatly enhanced communication on diversity topics, and globally, employees attended education on Diversity & Inclusion awareness.

Globally, approximately 50% of the workforce is female, with 11,428 females and 11,533 males as of June 30, 2021. In the II-VI’s Senior Leadership Team (“SLT”), which consists of senior directors and above, there are 20 females and 179 males. The SLT meets quarterly to discuss strategy, business trends, company operations, financials, and people programs. Our global footprint is diverse, with approximately 18,400 employees in the Asia-Pacific region, 1,000 in Europe, and 3,600 in the Americas.

Our success in developing and manufacturing many of our products depends on our ability to manufacture and tailor the optical and physical properties of technically challenging materials and components. The ability to produce, process and refine these complex materials, and to control their quality and in-process yields, is an expertise of the Company that is critical to the performance of our customers’ subsystems and systems. 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 network of worldwide manufacturing sites allows us to manufacture our products in regions that provide cost-effective and risk management advantages. We employ numerous advanced manufacturing technologies and systems at our manufacturing facilities. These include metal-organic chemical vapor deposition and molecular beam epitaxy reactors, automated computer numeric control optical fabrication, high-throughput thin-film coaters, nanoprecision metrology, and custom-engineered automated furnace controls for crystal growth processes. Manufacturing products for use across the electromagnetic spectrum requires the capability to repeatedly manufacture products with high yields to atomic tolerances. II-VI continuously updates its comprehensive quality management systems that feature manufacturing quality best practices. II-VI is committed to delivering products within specification, on time, and with high quality, with a goal of fully satisfying customers and continually improving.

We continue to focus our efforts to convert locations to renewable energy. During the past two fiscal years we have converted 15 of our sites to renewable-electricity contracts. In addition, II-VI participates in Apple’s Supplier Clean Energy Program, and all of our Apple production facilities are powered with 100% renewable energy.

Additionally, our Fremont, California, and Dallas, Texas, facilities are multiyear award recipients for continued compliance with local wastewater treatment programs. Additional information can be found on the Community & Environment section of our website at www.ii-vi.com. The website address is intended to be an inactive textual reference only. None of the information on, or accessible through, II-VI's website is part of this Annual Report on Form 10-K or is incorporated by reference herein.

Sources of Supply

In our production processes, we use numerous optical, electrical, and mechanical parts that are sourced from third-party supplies. These include integrated circuits, mechanical housings, and optical components, and we commonly refer to them as raw materials.

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. As a result of COVID-19, we have experienced some production delays due to shortages of raw materials, and we are driving the development of strategic second sources as part of our overall business continuity planning. We do occasionally experience problems associated with vendor-supplied 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 is discussed in greater detail in Item 1A – Risk Factors of this Annual Report.

Our Markets

Our market-focused businesses are currently organized by technologies and products. Our businesses address the following primary markets: optical and wireless communications, industrial, aerospace and defense, consumer electronics, semiconductor capital equipment, life sciences, and automotive. As we grow, we may add new primary markets.

Communications Market

II-VI’s optical communications and wireless products and technologies enable next-generation high-speed optical transmission systems, networks, and datacenter solutions necessary to meet the accelerating global bandwidth demand.

Demand for our products is largely driven by the continually growing need for additional network bandwidth created by the ongoing proliferation of data and video traffic from video conferencing for work, school, and leisure; video downloads and streaming; live TV; social networking; online gaming; file sharing; enterprise IP/internet traffic; cloud computing; and datacenter virtualization that must be handled by both wireline and wireless networks. This traffic increase reflects the recent shift to the work-from-home and study-from-home approach, which was driven by the COVID-19 pandemic but is expected to continue. Mobile traffic is increasing as a result of the proliferation of smartphones, tablet computers, and other mobile devices.

We are a global technology leader in optical communications, providing materials, subcomponents, components, modules, and subsystems to optical component and module manufacturers, networking equipment manufacturers, datacenter operators, and telecom service providers. We design products that meet the increasing demands for network bandwidth and data storage.

Our optical communications products can be divided into two main groups, optical transmission and optical transport.

Our optical transmission products consist primarily of transmitters, receivers, transceivers, transponders, and active optical cables, which provide the fundamental optical-electrical, or optoelectronic, interface for interconnecting the electronic equipment used in networks. This equipment includes switches, routers, and servers used in wireline networks, as well as antennas and base stations used in wireless networks. These products rely on advanced components such as semiconductor lasers and photodetectors, in conjunction with integrated circuits and novel optoelectronic packaging to provide a cost-effective means for transmitting and receiving digital signals over fiber-optic cable at speeds ranging from less than 1 Gbps to more than 400 Gbps, over distances of less than 10 meters to more than 5,000 kilometers, using a wide range of network protocols and physical configurations.

Our optical transport products are at the core of both terrestrial and undersea optical networks. Our market-leading 980 nm pump lasers are the key enablers of our erbium-doped fiber amplifiers, which boost the power of optical signals in fiber-optic cables at intervals spanning 80 km, typically, to allow high-speed signals to be transmitted over longer distances. Our latest generation of components for coherent transceivers is critical to a new generation of small-size, long-reach DWDM transmission modules operating from 100 Gbps to 1 Tbps and beyond.

Customers continue to rely on us for our industry-leading optical amplification and embedded monitoring solutions for their next-generation ROADM systems to compensate for inherent signal loss and to monitor signal integrity. Our proprietary OTDR modules allow systems to automatically detect and pinpoint issues along the transmission path in real time. Together with our OCM solutions, which monitor the optical power of the channels transmitted in a fiber-optic link, they enable real-time intelligence to perform preventive maintenance so as to preserve data transmission. In addition, we offer a portfolio of WSS products, which we also incorporate into ROADM line cards and subsystems.

Our proven experience in both transmission and transport allows us to effectively address the emerging DCI market. Our transceivers, submodules, pluggable amplifiers, and configurable line cards are able to meet the requirements of low power consumption, compactness, ease of installation and operation, and cost savings, which are often mandatory features in the DCI market.

The accelerating adoption of applications such as cloud computing is driving the rapid growth of datacenter buildouts. Our high-speed 25 Gbps VCSELs enable transceivers for intra-datacenter communication. Our miniature WDM thin-film filter assemblies are used to increase the bandwidth within 100 GbE transceivers by combining wavelengths at the transmitter end and separating them out at the receiver end.

In the mobile wireless market, II-VI is a global leader in the strategic supply chain for materials and devices utilized in the latest 4G and 5G base station infrastructure. The deployment of 5G wireless is accelerating globally, driving the demand for RF power amplifiers that can operate efficiently in new high-frequency bands and be manufactured on a technology platform that can scale

13

to meet the growing demand. GaN-on-SiC RF power amplifiers have superior performance, compared with devices based on silicon, over a wide spectrum of 5G operating frequencies in the gigahertz range, including in the millimeter-wave bands.

We are a market leader in the technology development and large-volume manufacturing of 100 mm and 150 mm semi-insulating SiC substrates. These substrates are utilized by customers worldwide to manufacture GaN-on-SiC HEMT RF power amplifier devices that are embedded in remote radio heads in 4G and 5G wireless base stations. In areas of high bandwidth demand, 5G antennas with beamforming technology utilizing multiple devices per antenna are expected to be densely deployed, increasing the demand for GaN-on-SiC power amplifiers by approximately an order of magnitude or more versus 4G antennas. Looking forward, II-VI continues to advance the state of the art in SiC substrates, with a strong technology portfolio of 30 active patents using highly differentiated and proprietary manufacturing platforms and technologies including crystal growth, substrate fabrication, and polishing. Our recent demonstration of the world’s first prototype 200 mm semi-insulating SiC substrates will enable the RF power amplifier market to continue to scale, increasingly replacing functions performed by devices based on silicon and enabling new applications.

Leveraging this materials expertise, II-VI has invested aggressively in a world-class 150 mm compound semiconductor manufacturing platform and is developing a fully vertically integrated, 150 mm wafer fabrication capability to manufacture the state-of-the-art GaN-on-SiC HEMT devices that will enable these next-generation wireless networks.

Industrial Market

Our laser optics and solutions for the industrial market remain well-positioned, although we were impacted in FY21 by the global industrial slowdown associated with COVID-19. Our vertically integrated and market-leading ZnSe optics and components, due to their inherent low loss at around the 10-micron wavelength, have enabled high-power CO2 laser systems for many decades and remain critical to the steady stream of new deployments as well as to continued operation, serving as replacement optics for the installed base of CO2 lasers. II-VI continues to introduce products that address new and growing applications for low-power CO2 lasers, such as drilling and cutting plastics, textiles, leather, wood, and other organic materials, for which the CO2 laser’s 10-micron wavelength is ideally suited. The 5G market enabled strong growth for our low-power CO2 drilling machines. CO2 lasers are also at the core of EUV lithography systems, which enable a new generation of smaller and more powerful integrated circuits.

Fiber lasers that operate at about the 1-micron wavelength in pulsed or continuous mode have taken a central role in many industrial applications, especially for metal cutting and welding along with precision machining such as marking and microdrilling. II-VI supplies a broad range of materials, components, and subsystems that enable many functions within these fiber lasers, from the laser chips that generate the input optical power to the beam delivery systems that direct the output optical power to the target. The same set of II-VI products is at the core of existing and emerging direct-diode laser systems.

II-VI’s broad portfolio of coated optics and crystal materials serves all of these growing laser markets.

Semiconductor Capital Equipment Market

Semiconductor capital equipment requires advanced materials to meet the need for tighter tolerances, enhanced thermal stability, faster wafer transfer speeds, and reduced stage settling times. Our metal-matrix composites and reaction-bonded ceramics enable these applications, thanks to their optimum combination of light weight, strength, hardness, and coefficient of thermal expansion. Our reaction-bonded SiC materials are used to manufacture wafer chucks, lightweight scanning stages, and high-temperature, corrosion-resistant wafer support systems. Our cooled SiC mirrors and precision patterned reticles are used in the illumination systems of lithography tools.

Our products enable legacy EUV lithography equipment that is widely deployed in semiconductor fabs. In the emerging market of EUV lithography systems, CO2 lasers are used to generate extreme-ultraviolet light. These CO2 lasers and beam delivery systems leverage our broad portfolio of CO2 laser optics, CdTe modulators, and high-power damage-resistant polycrystalline CVD diamond windows to route the powerful laser beam to a tin droplet from which EUV light will emanate. Due to its very high mechanical and thermal performance characteristics, our reaction-bonded SiC is used in structural support systems that are integral to EUV lithography optics to meet critical requirements for optical system stability.

Life Sciences Market

Within the life sciences end market, II-VI focuses on analytical instrumentation that integrates light and/or thermal management solutions. We segment this market into three application areas (biotechnology, medical laser, and scientific) and deliver targeted and unique product portfolios for each segment. II-VI vertically integrates from the component-level to more complex subassemblies and even full systems. Applications within the biotechnology segment include flow cytometry, genome sequencing, PCR, molecular diagnostics, imaging, and spectroscopy, to name a few. Our broad product portfolio delivers solutions covering illumination, light management, and thermal control. Visible-wavelength “QOMO” lasers and multicolored laser engines provide low-noise, high-performance, reliable light sources. Optical components and subassemblies such as filters, lenses, flow cells, gratings, objective lenses, and patterned reticles are embedded into these instruments to manage light delivery. Our state-of-the-art thermal engines precisely control temperature and uniformity across large areas such as plate and block assemblies, even extending to reagent or sample chilling.

Medical laser and clinical procedures are increasingly performed with systems that integrate our lasers, optics, and thermal solutions. These applications are performed at or near the patient, requiring extreme precision and often complex designs and typically reach into the NIR and IR wavelengths. Applications are varied, from laser-based treatments and surgeries to medical imaging and even point of care. II-VI’s semiconductor laser bars and stacks are used in applications such as hair and wrinkle removal. Crystals and laser cavities, along with custom-designed lens assemblies, are used for ophthalmic, dental, and dermatological surgeries. Finally, thermal components and subassemblies deliver solutions for medical-based applications such as delivering heating and cooling to the human body and medical laser temperature control.

For the scientific segment, II-VI's solutions are the building blocks of molecular spectroscopy and imaging-based platforms. These tools typically target environmental applications such as water, air, food and beverage, pharmaceutical, and agricultural testing and monitoring. II-VI continues to leverage its core laser, optics, and temperature-control expertise to deliver custom components and subassembly-level solutions at all wavelengths, from UV to NIR and IR.

Consumer Electronics Market

15

II-VI manufactures VCSELs, VCSEL arrays, and optical filters for the consumer electronics market. Our VCSEL products leverage our world-class 6-inch GaAs platform, combining our epitaxial wafer growth and wafer fabrication capabilities. Our VCSELs have been used in consumer products such as computer mice and mobile phones for many years. Our VCSELs are also widely deployed in datacenters and HDMI optical cables as well as in vehicle steering wheels. This expertise in VCSEL technology has been leveraged for the growing 3D sensing market. 3D sensing was the first application to drive the demand for relatively large two-dimensional VCSEL arrays. A typical design for 3D sensing requires tens or hundreds of VCSELs per chip in order to scale up the optical power required for, for example, face recognition. Therefore, 3D sensing applications created the need to scale up manufacturing to 6-inch wafer processing. Today, II-VI is one of the very few vertically integrated 6-inch VCSEL manufacturers with a proven track record in high-volume manufacturing of high-reliability, large multi-emitter VCSEL dies designed for 3D sensing. An increasing number of consumer devices are coming on the market with embedded VCSELs, including multiple smartphones and tablets, smart watches, and household robots.

Automotive Market

II-VI is a global leader in SiC substrates for power electronics that improve the energy efficiency of electric and hybrid-electric vehicles. Power electronics based on SiC enable systems to achieve significantly improved power utilization and conversion efficiencies, lower operating temperatures, and reduced thermal loads. This in turn enables either increased driving range or reductions in required battery capacity for a given range, which results in a significant cost reduction. Our comprehensive understanding of crystal growth and materials processing was acquired over decades of sustained R&D and manufacturing, allowing us to continuously evolve our technology and IP portfolio. We offer a full range of substrate diameters, including the world’s first 200 mm substrate.

Item 1A. RISK FACTORS

The following are certain risk factors that could affect our business, results of operations, financial position or cash flows. These risk factors should be considered along with the 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 Relating to Our Business and Our Industry

Investments in future markets of potential significant growth may not result in the expected return.

We continue to make investments in programs with the goal of gaining a greater share of end markets using semiconductor lasers and other components, including those used for 3D sensing and emerging 5G technology. 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.

Our competitive position depends on our ability to develop new products and processes.

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 market developments to address increasingly sophisticated customer requirements. 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 faster 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.

A widespread health crises could materially and adversely affect our business, financial condition, and results of operations.

The outbreak of a widespread health crisis, whether global in scope or localized in an area in which we, our customers or our suppliers do business, could have a material adverse effect on our operations and the operations of our suppliers and customers. Potential impacts on our operations include:

•significant reductions in demand for one or more of our products or a curtailment to one or more of our product lines caused by, among other things, any temporary inability of our customers to purchase and utilize our products in next-stage manufacturing due to shutdown orders or financial hardship;

•workforce constraints triggered by any applicable shutdown orders or stay-at-home polices;

•disruptions to our third-party manufacturing and raw materials supply arrangements caused by constraints over our suppliers’ workforce capacity, financial, or operational difficulties;

•heightened risk and uncertainty regarding the loss or disruption of essential third-party service providers, including transportation services, contract manufacturing, marketing, and distribution services;

•requirements to comply with governmental and regulatory responses such as quarantines, import/export restrictions, price controls, or other governmental or regulatory actions, including closures or other restrictions that limit or close our operating and manufacturing facilities, restrict our workforce’s ability to travel or perform necessary business functions, or otherwise impact our suppliers or customers, which could adversely impact our operating results; and

•increased operating expenses and potentially reduced efficiency of operations.

In the early stages of the outbreak of the global novel coronavirus (COVID-19) in 2020, we closely monitored the impact of the COVID-19 pandemic on all aspects of our business, including the impact to our suppliers, customers, and employees, as well as

25

the impact to the countries and markets in which we operate. We began focusing intensely on mitigating the adverse impacts of COVID-19 on our foreign and domestic operations, starting by protecting our employees, suppliers, and customers. While we believe that we have been successful in identifying, managing, and mitigating the economic disruption impacts of the COVID-19 pandemic on us, we cannot provide any assurance that we similarly will be able to mitigate the impacts of any future widespread health crises, including as a result of any variants of COVID-19. Factors beyond our current knowledge or control, including the duration and severity of any outbreak, as well as any resulting governmental and regulatory actions, could cause any such crisis to have a material adverse effect on our business, operating results, and financial condition.

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

Current and future conditions in the global economy have an inherent degree of uncertainty. As a result, it is difficult to estimate the level of growth or contraction of the global economy as a whole. It is even more difficult to estimate growth or contraction in various parts, sectors, and regions of the economy, including the industrial, aerospace and defense, optical communications, telecommunications, semiconductor, consumer, and medical and life science markets in which we participate. All aspects of our forecasts depend on estimates of growth or contraction in the markets we serve. Thus, prevailing global economic uncertainties render estimates of future income and expenditures very difficult to make.

Global economic downturns may affect industries in which our customers operate. These changes could include decreases in the rate of consumption or use of our customers’ products. Such conditions could have a material adverse effect on demand for our customers’ products and, in turn, on demand for our products.

Adverse changes may occur in the future as a result of declining or flat global or regional economic conditions, fluctuations in currency and commodity prices, wavering confidence, capital expenditure reductions, unemployment, decline in stock markets, contraction of credit availability, or other factors affecting economic conditions. For example, factors that may affect our operating results include disruption in the credit and financial markets in the United States, Europe, and elsewhere, adverse effects of slowdowns in the U.S., European, or Chinese economies, reductions or limited growth in consumer spending or consumer credit, global trade tariffs, and other adverse economic conditions that may be specific to the Internet, e-commerce, and payments industries.

These changes may negatively affect sales of products and increase exposure to losses from bad debt and commodity prices, the cost and availability of financing, and costs associated with manufacturing and distributing products. Any economic downturn could have a material adverse effect on our business, results of operations, or financial condition.

Some systems that use our products are complex in design, and our products may contain defects that are not detected until deployed, which could increase our costs, reduce our revenues, cause us to lose key customers, or expose us to litigation related to our products.

Some systems that use our products are inherently complex in design and require ongoing maintenance. Our customers may discover defects in our products after the products have been fully deployed and operated under peak stress conditions. In addition, some of our products are combined with products from other vendors which may contain defects. Should problems occur, it may be difficult to identify the source of the problem. 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. The occurrence of any one or more of the foregoing factors could have a material adverse effect on our business, results of operations, or financial condition.

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.

Our competitive position may still require significant investments.

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

26

strategic acquisition 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 may be unable to successfully implement our acquisitions strategy or integrate acquired companies and personnel with existing operations.

We have in the past acquired several companies, including the completion of our acquisition of Finisar Corporation (“Finisar”) in 2019. We may continue to expand and diversify our operations with additional acquisitions, such as our pending acquisition of Coherent, Inc. (“Coherent”). 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 antitrust laws and other regulations may limit our ability to acquire targets 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, we may be unsuccessful in integrating acquired companies or product lines with existing operations, or the integration may be more difficult or more costly than anticipated. 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:

•unexpected losses of key employees of the acquired company;

•conforming the acquired company’s standards, processes, procedures, and controls with our operations, including integrating enterprise resource planning systems and other key business applications;

•coordinating new product and process development;

•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; and

•diversion of management’s attention from other business concerns.

•In connection with acquisitions, we may:

◦use a signification portion of our available cash;

◦issue equity securities, which would dilute current shareholders’ percentage ownership;

◦incur significant debt;

◦incur or assume contingent liabilities, known or unknown, including potential lawsuits, infringement actions, or similar liabilities;

◦incur impairment charges related to goodwill or other intangibles; and

◦face antitrust or other regulatory inquiries or actions.

In addition, the market prices of our outstanding securities could be adversely affected if the effect of any acquisitions on our consolidated financial results is dilutive or is below the market’s or financial analysts’ expectations, or if there are unanticipated changes in the business or financial performance of the acquired or combined company. Any failure to successfully integrate acquired businesses may disrupt our business and adversely impact our business, results of operations, or financial condition.

Although we expect that our acquisitions will result in cost savings, synergies, and other benefits, we may not realize those benefits, or be able to retain those benefits even if realized.

The success of our acquisitions will depend in large part on our success in integrating the acquired operations, strategies, technologies, and personnel. We may fail to realize some or all of the anticipated benefits of an acquisition if the integration process takes longer than expected or is more costly than expected. If we fail to meet the challenges involved 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.

Potential difficulties that we may encounter in the integration process include:

27

•the integration of management teams, strategies, technologies and operations, products, and services;

•the disruption of ongoing businesses and distraction of their respective management teams from ongoing business concerns;

•the retention of, and possible decrease in business from, existing customers

•the creation of uniform standards, controls, procedures, policies, and information systems;

•the reduction of the costs associated with combined operations;

•the integration of corporate cultures and maintenance of employee morale;

•the retention of key employees; and

•potential unknown liabilities associated with the acquired business.

The anticipated cost savings, synergies, and other benefits of any acquisition typically assume a successful integration of the acquired business and are based on projections and other assumptions, which are inherently uncertain. Even if integration is successful, anticipated cost savings, synergies, and other benefits may not be achieved.

Our future success depends on continued international sales, and our global operations are complex and present multiple challenges to manage.

We anticipate that international sales will continue to account for a significant portion of our revenues for the foreseeable future. The failure to maintain our current volume of international sales could materially affect our business, results of operations, financial condition, and/or cash flows.

We manufacture products in Australia, China, Germany, Malaysia, the Philippines, Singapore, South Korea, Sweden, Switzerland, the United Kingdom, the United States, and Vietnam, and through a contract manufacturer in Thailand. We also maintain direct sales offices in Belgium, Canada, China, Germany, Hong Kong, Italy, Japan, South Korea, Switzerland, Taiwan, and the United Kingdom. Our operations vary by location and are influenced on a location-by-location basis by local customs, languages, and work practices, as well as different local weather conditions, management styles, and education systems. In addition, multiple complex issues may arise concurrently in different countries, potentially hampering our ability to respond in an effective and timely manner. Any inability to respond in an effective and timely manner to issues in our global operations could have a material adverse effect on our business, results of operations, or financial condition.

We are subject to complex and rapidly changing import and export regulations which could limit our sales and decrease our profitability.

We are subject to the passage of and changes in the interpretation of regulation by U.S. 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 regulations 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 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 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.

Changes in trade policies, such as increased import duties, could increase the costs of goods imported into the United States or China.

In March 2018, President Trump announced new steel and aluminum tariffs. Then, in July 2018, the United States imposed increased tariffs on products of Chinese origin, and China responded by increasing tariffs on U.S.-origin goods. On the export side, denial orders and placing companies on the U.S. entity list could decrease our access to customers and markets and materially impact our revenues in the aggregate. In April 2018, for example, the U.S. Department of Commerce issued a denial

28

order against two companies in the telecommunications market. In 2019 and 2020, the U.S. Department of Commerce placed a number of entities, including Huawei, on the U.S. Entity List. If we cannot obtain relief from, or take other action to mitigate the impact of, these additional duties and restrictions and duties, our business and profits may be materially and adversely affected. Further changes in the trade policy of the United States or of other countries in which we do cross-border business, or additional sanctions, could result in retaliatory actions by other countries that could materially and negatively impact the volume of economic activity in the United States or globally, which, in turn, may decrease our access to customers and markets, reduce our revenues, and increase our operating costs.

Our association with customers that are or become subject to U.S. regulatory scrutiny or export restrictions could negatively impact our business and create instability in our operations. Governmental actions such as these could subject us to actual or perceived reputational harm among current or prospective investors, suppliers or customers, customers of our customers, other parties doing business with us, or the general public. Any such reputational harm could result in the loss of investors, suppliers, or customers, which could harm our business, financial condition, operating results, or prospects.

Exports of certain of our products are subject to export controls imposed by the U.S. government and administered by the U.S. Departments of State and Commerce. In certain instances, these regulations may require pre-shipment authorization from the administering department. For products subject to the Export Administration Regulations (EAR), administered by the Department of Commerce’s Bureau of Industry and Security, the requirement for a license is dependent on the type and end use of the product, the final destination, the identity of the end user, and whether a license exception might apply. Virtually all exports of products subject to the International Traffic in Arms Regulations (ITAR), administered by the Department of State’s Directorate of Defense Trade Controls, require a license. Certain of our products are subject to EAR controls.

Additionally, certain other products that we sell, including certain products developed with government funding, are subject to ITAR. Products developed and manufactured in our foreign locations are subject to export controls of the applicable foreign nation. Given the current global political climate, obtaining export licenses can be difficult and time-consuming. Failure to obtain export licenses for these shipments, or having one or more of our customers be restricted from receiving exports from us, could significantly reduce our revenue and materially adversely affect our business, financial condition, and results of operations. Compliance with regulations of the United States and other governments also subjects us to additional fees and costs. The absence of comparable restrictions on competitors in other countries may adversely affect our competitive position.

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.

We may not be able to settle conversions of our convertible senior notes in cash or repurchase the notes in accordance with their terms.

Holders of our outstanding 0.25% Convertible Senior Notes due 2022 (the “2022 Notes”) and the 0.50% Convertible Senior Notes due 2036 issued by Finisar (the “2036 Notes”) have the right to require us to repurchase all or a portion of their convertible notes for cash upon the occurrence of a fundamental change (as defined in the respective indentures governing such notes) at a repurchase price equal to 100% of the principal amount of the convertible notes to be repurchased, plus accrued and unpaid interest. Holders of the 2036 Notes also have the right to require Finisar to repurchase all or a portion of their 2036 Notes for cash on certain specified dates at a repurchase price equal to 100% of the principal amount of the 2036 Notes to be

29

repurchased, plus accrued and unpaid interest. The next such repurchase date for the 2036 Notes is December 15, 2021. In addition, upon conversion of such convertible notes, we will be required to make cash payments in respect of such convertible notes being converted. However, we may not have enough available cash or be able to obtain financing at the time we are required to make repurchases of surrendered convertible notes or pay cash with respect to convertible notes being converted.

In addition, our ability to repurchase or to pay cash upon conversion of our convertible notes may be limited by law, regulatory authority, or agreements governing our future indebtedness. Our failure to repurchase convertible notes at a time when the repurchase is required or to pay any cash upon conversion of the convertible notes as required would constitute a default under the applicable indenture. A default under the applicable indenture or the fundamental change itself also could lead to a default under agreements governing our existing credit facility or any of our other current or future indebtedness. If the payment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the convertible notes or to pay cash upon conversion of any such convertible notes.

Our current credit agreement restricts our operations, particularly our ability to respond to changes or to take certain actions regarding our business.

Our amended and restated credit agreement, dated as of September 24, 2019, by and among us, Bank of America, N.A., as Administrative Agent, Swing Line Lender and an L/C Issuer, and the other lenders party thereto (the “Credit Agreement”) contains a number of restrictive covenants that may impose operating and financial restrictions on us and limit our ability to engage in acts that may be in our long-term best interest, including restrictions on our ability to incur indebtedness, grant liens, undergo certain fundamental changes, dispose of assets, make certain investments, enter into certain transactions with affiliates, and make certain restricted payments, in each case subject to limitations and exceptions set forth in the Credit Agreement.

The Credit Agreement also contains customary events of default that include, among other things, certain payment defaults, covenant defaults, cross-defaults to other indebtedness, change of control defaults, judgment defaults, and bankruptcy and insolvency defaults. Such events of default may allow the creditors to accelerate the related debt and may result in the acceleration of any other debt to which a cross-acceleration or cross-default provision applies, which could have a material adverse effect on our business, operations, and financial results. Furthermore, 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. In the event that our lenders accelerated the repayment of the borrowings, we may not have sufficient assets to repay that indebtedness. Any acceleration of amounts due under the Credit Agreement would likely have a material adverse effect on us. 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.

We may fail to accurately estimate the size and growth of our markets and our customers’ demands.

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.

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 may cause our customers to significantly reduce their demand. 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. Unexpected declines in customer demands can result in excess or obsolete inventory and additional charges. 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 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.

30

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. 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 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 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, 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 into 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.

A significant portion of our business is dependent on cyclical industries.

Our business is dependent on the demand for products produced by end-users of industrial lasers, optical communication products, components for semiconductor capital equipment, and components for 3D sensing. Many of these end-users are in industries that have historically experienced a highly cyclical demand for their products. As a result, demand for our products is subject to these cyclical fluctuations. Fluctuations in demand could have a material adverse effect on our business, results of operations or financial condition.

Our global operations are subject to complex legal and regulatory requirements.

We manufacture products in Australia, China, Germany, Malaysia, the Philippines, Singapore, South Korea, Sweden, Switzerland, the United Kingdom, the United States, and Vietnam, and through a contract manufacturer in Thailand. We also maintain direct sales offices in Belgium, Canada, China, Germany, Hong Kong, Italy, Japan, South Korea, Switzerland, Taiwan, and the United Kingdom. Operations inside and outside of the United States are subject to many legal and regulatory requirements, some of which are not aligned with others. These include tariffs, quotas, taxes and other market barriers, restrictions on the export or import of technology, potentially limited intellectual property protection, import and export requirements and restrictions, anti-corruption and anti-bribery laws, foreign exchange controls and cash repatriation restrictions, foreign investment rules and regulations, data privacy requirements, competition laws, employment and labor laws, pensions and social insurance, and environmental health and safety laws and regulations.

Compliance with these laws and regulations can be onerous and expensive, and requirements differ among jurisdictions. New laws, changes in existing laws, and abrogation of local regulations by national laws may result in significant uncertainties in how they will be interpreted and enforced. Failure to comply with any of these foreign laws and regulations could have a material adverse effect on our business, results of operations, or financial condition.

Changes in laws and regulations governing data privacy and data protection could have a material adverse impact on our business.

We are subject to many data privacy, data protection, and data breach notification laws, including the European Union General Data Protection Regulation (GDPR), which became effective in 2018. While we have taken measures to assess the requirements of, and to comply with, the GDPR, as well as new and existing data-related laws and regulations of other jurisdictions, these measures may be challenged, including by authorities that regulate data-related compliance. We could incur significant expense in facilitating and responding to investigations, and if the measures we have taken prove to be inadequate, we could face fines, penalties, or damages, and incur reputational harm, which could have a material adverse impact on our business.

31

Data breach incidents and breakdowns of information and communication technologies could disrupt our operations and impact our financial results.

In the course of our business, we collect and store sensitive data, including intellectual property (both our own and that of our customers), as well as proprietary business information. We could be subject to service outages or breaches of security systems which may result in disruption, unauthorized access, misappropriation, or corruption of this information. Security breaches of our network or data, including physical or electronic break-ins, vendor service outages, computer viruses, attacks by hackers or similar breaches can create system disruptions, shutdowns, and unauthorized disclosure of confidential information. If we are unable to prevent or contain such security or privacy breaches, our operations could be disrupted or we could suffer legal claims, loss of reputation, financial loss, property damage, or regulatory penalties.

We have entered into supply agreements that commit us to supply products on specified terms.

We have supply agreements with some customers that require us to supply products and allocate sufficient capacity to make these products. We have also agreed to pricing schedules and methodologies that could result in penalties if we fail to meet development, supply, capacity, and quality commitments. Failure to do so may cause us to be unable to generate the amount of revenue or the level of profitability we expect from these arrangements. Our ability to realize a profit under some of these agreements will be subject to the level of customer demand, the cost of maintaining facilities and manufacturing capacity, and supply chain capability. If we fail to fulfill our commitments under these supply agreements, our business, after using all remedies available, financial conditions, and results of operations may suffer a material adverse effect.

We depend on highly complex manufacturing processes that require feeder 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. 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.

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.

We produce hydrogen selenide gas, which is used in our production of ZnSe. There are risks inherent in the production and handling of such material. Our lack of proper handling of hydrogen selenide could require us to curtail our production of the gas. Our potential inability to internally produce hydrogen selenide could have a material adverse effect on our business, results of operations, or financial condition.

In addition, we produce and use other 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 on a timely basis could have a material adverse effect on our business, results of operations, or financial condition.

Increases in commodity prices 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. Our businesses purchase, produce, and sell high-purity selenium and other raw materials based upon quoted market prices from minor metal exchanges. The negative impact from increases in commodity prices might not be recovered through our product sales, which could have a material adverse effect on our net earnings and financial condition.

We use and generate potentially hazardous substances that are subject to stringent environmental regulations.

Hazardous substances used or generated in some of our research and manufacturing facilities are subject to stringent environmental regulation. We believe that our handling of such substances is in material compliance with applicable environmental, safety, and health regulations at each operating location. We invest substantially in proper personal protective equipment and process controls, including monitoring and specialized training, to minimize risks to employees, surrounding communities, and the environment that could result from the presence and handling of such hazardous substances. When exposure problems or potential exposure problems have been uncovered, corrective actions have been implemented, and re-occurrence has been minimal or nonexistent.

32

We have in place an emergency response plans with respect to our generation and use of the hazardous substances hydrogen selenide, hydrogen sulfide, arsine, and phosphine. Special attention has been given to all procedures pertaining to these gaseous materials to minimize the chance of its accidental release into the atmosphere.

With respect to the manufacturing, use, storage, and disposal of the low-level radioactive material thorium fluoride, our facilities and procedures have been inspected and licensed by the Nuclear Regulatory Commission. Thorium-bearing by-products are collected and shipped as solid waste to a government-approved low-level radioactive waste disposal site in Clive, Utah.

The generation, use, collection, storage, and disposal of all other hazardous by-products, such as suspended solids containing heavy metals or airborne particulates, are believed by us to be in material compliance with regulations. We believe that we have obtained all of the permits and licenses required for operation of our business.

Although we do not know of any material environmental, safety, or health problems in our properties, processes, or products, there can be no assurance that problems will not develop in the future that could have a material adverse effect on our business, results of operations, or financial condition.

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, 2021, we had approximately $1.4 billion of outstanding indebtedness on a consolidated basis. Our indebtedness could have important consequences for us, including:

•making it more difficult for us to satisfy 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.

Unfavorable changes in tax rates, tax liabilities, or tax accounting rules could negatively affect future results.

As a global company, we are subject to taxation in the United States and various other countries and jurisdictions. As such, we must exercise a level of judgment in determining our worldwide tax liabilities. Our future tax rates could be affected by changes in the composition of earnings in countries with differing tax rates or changes in tax laws. Changes in tax laws or tax rulings may have a significantly adverse impact on our effective tax rate.

The enactment of the Tax Cuts and Jobs Act (the “Tax Act”) in December 2017 significantly affected U.S. tax law by changing how the United States imposes tax on multinational corporations. The U.S. Department of Treasury has broad authority under the Tax Act to issue regulations and interpretive guidance. We have applied available guidance to estimate our tax obligations, but new guidance issued by the U.S. Treasury Department may cause us to make adjustments to our tax estimates in future periods.

In addition, we are subject to regular examination of our income tax returns by the U.S. Internal Revenue Service and other tax authorities. We regularly assess the likelihood of favorable or unfavorable outcomes resulting from these examinations to

33

determine the adequacy of our provision for income taxes. Although we believe our tax estimates are reasonable, there can be no assurance that any final determination will not be materially different from the treatment reflected in our historical income tax provision and accruals, which could materially and adversely affect our business, results of operation, or financial condition.

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 may be exposed to business interruptions due to extreme weather caused by climate change and deforestation, force majeure catastrophes, natural disaster, pandemic, terrorism, or acts of war that are beyond our control. Disruptions to our facilities or systems, or to those of our key suppliers, could also interrupt operational processes and adversely impact our ability to manufacture our products and provide services and support to our customers. As a result, our business, results of operations, or financial condition could be materially adversely affected.

Our success depends on our ability to attract, retain, and develop key personnel and requires continued good relations with our employees.

We are highly dependent upon the experience and continuing services of certain scientists, engineers, production, 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.

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.

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

We may be adversely affected by climate change regulations.

In many of the countries in which we operate, government bodies are increasingly enacting legislation and regulations in response to potential impacts of climate change. These laws and regulations may be mandatory. They have the potential to impact our operations directly or indirectly as a result of required compliance by our customers or our supply chain. Inconsistency of regulations may also affect the costs of compliance with such laws and regulations. Assessments of the potential impact of future climate change legislation, regulation, and international treaties and accords are uncertain, given the wide scope of potential regulatory change in countries in which we operate.

We may incur increased capital expenditures resulting from required compliance with revised or new legislation or regulations, added costs to purchase raw materials, lower profits from sales of our products, allowances or credits under a “cap and trade” system, increased insurance premiums and deductibles as new actuarial tables are developed to reshape coverage, changes in competitive position relative to industry peers, changes to profit or loss arising from increased or decreased demand for goods produced by us, or changes in costs of goods sold.

We depend on large purchases from a few significant customers, and any loss, cancellation, reduction, or delay in purchases by these customers could harm our business.

A small number of customers have consistently accounted for a significant portion of our revenues, although none individually represent greater than 10% of total revenues. Our success will depend on our continued ability to develop and manage relationships with our major customers. 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 major 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.

34

Our dependence on large orders from a relatively small number of customers makes our relationship with each customer critically important to our business. We cannot ensure that we will be able to retain our major customers, attract additional customers, or that our 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 customers. We have in the past experienced delays and reductions in orders from some of our major customers. In addition, our customers have in the past sought price concessions from us, and we expect that they will continue to do so in the future. 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 key customers. Further, some of our 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 major 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.

The manufacturing of our products may be adversely affected if we are unable to manufacture certain products in our manufacturing facilities.

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 goods. For some of the components and finished goods, we are the sole manufacturer. Our manufacturing processes are highly complex, and issues are often difficult to 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 financial condition and results of operations. 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, 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 those products. 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.

Failure to accurately forecast our revenues could result in additional charges for obsolete or excess inventories or noncancellable purchase commitments.

We base many of our operating decisions, and enter into purchase commitments, on the basis of anticipated revenue trends that are highly unpredictable. Some of our purchase commitments are not cancellable, and in some cases we are required to recognize a charge representing an amount of material or capital equipment purchased or ordered that exceeds our actual requirements. 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.

If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, our ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired.

As a public company, we are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, the Sarbanes-Oxley Act of 2002, as amended (“the Sarbanes-Oxley Act”), and Nasdaq listing requirements. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. In order to maintain and improve the effectiveness of our disclosure controls and procedures and internal control over financial reporting, we have expended, and anticipate that we will continue to expend, significant resources, including accounting-related costs and significant management oversight.

Any failure to develop or maintain effective controls, or any difficulties encountered in their implementation or improvement, could delay the reporting of our financial results or cause us to be subject to investigations, enforcement actions by regulatory agencies, stockholder lawsuits, or other adverse actions requiring us to incur defense costs or pay fines, settlements, or judgments. Any such failures or difficulties could also cause investors to lose confidence in our reported financial and other information, which would likely have a negative effect on the trading price of our common stock. In addition, if we are unable to continue to meet these requirements, we may not be able to remain listed on the Nasdaq Stock Market.

Risks Relating to Our Pending Acquisition of Coherent

The market prices of our securities after completion of our pending acquisition of Coherent may be affected by factors different from those currently affecting the markets for our securities or securities issued by Coherent.

Our business differs from that of Coherent. Accordingly, our results of operations and the market price of our securities after the completion of our pending acquisition of Coherent may be affected by factors different from those currently affecting the independent results of operations of each company. In addition, the issuance of shares of our common stock as part of the merger consideration payable in connection with the acquisition could on its own have the effect of depressing the market prices for our securities, including our common stock and our 6.00% Series A Mandatory Convertible Preferred Stock (“Mandatory Convertible Preferred Stock”). Further, many Coherent stockholders may decide not to hold the shares of our common stock that they receive as merger consideration. Other Coherent stockholders, such as funds with limitations on their permitted holdings of stock in individual issuers, may be required to sell the shares of our common stock that they receive as merger consideration. Any such sales of our common stock could have the effect of depressing the market prices for our securities

There can be no assurance that we will be able to secure the funds necessary to pay the cash portion of the merger consideration payable in our acquisition of Coherent, in a timely manner or at all.

We intend to finance part of the cash portion of the merger consideration payable in our acquisition of Coherent with the proceeds of debt financing. To this end, we have entered into a debt commitment letter (the “Debt Commitment Letter”) containing commitments for a senior secured term loan “A” facility in an aggregate principal amount of $850 million, a senior secured term loan “B” facility in an aggregate principal amount of $2,800 million, a senior secured revolving credit facility in an aggregate principal amount of $350 million and a senior unsecured bridge loan facility in an aggregate principal amount of $1,125 million. We have not entered into any definitive agreement for this debt financing or other financing arrangements in lieu thereof, and the obligation of the lender to provide the debt financing under the Debt Commitment Letter is subject to a number of customary conditions. There is a risk that these conditions will not be satisfied and the debt financing may not be available when required.

We also intend to finance part of the cash portion of the merger consideration with the proceeds of equity investments made by BCPE Watson (DE) SPV, LP, an affiliate of Bain Capital Private Equity, LP (“BCPE”). To this end, on March 30, 2021, we entered into an amended and restated investment agreement (the “Investment Agreement”) with BCPE. On March 31, 2021, we issued and sold 75,000 shares of a new Series B-1 Convertible Preferred Stock, no par value (“Series B-1 Preferred Stock”), to BCPE for an aggregate purchase price of $750 million. Subject to the terms and conditions of the Investment Agreement, we and BCPE also have agreed that we will issue and sell to BCPE, immediately prior to the closing of our acquisition of Coherent, an aggregate of 140,000 shares of a new Series B-2 Convertible Preferred Stock, no par value (“Series B-2 Preferred Stock” and together with Series B-1 Preferred Stock, the “Series B Preferred Stock”), for an aggregate purchase price of $1.4 billion. However, the issuance and sale of the Series B-2 Preferred Stock to BCPE is subject to a number of customary conditions, and there can be no assurance that this part of the equity financing will be completed.

In the event that the debt financing contemplated by the Debt Commitment Letter or the remaining investment contemplated by the Investment Agreement is not consummated, there is a risk that alternate financing may not be available on acceptable terms, in a timely manner or at all. Although our obligation to consummate our acquisition of Coherent is not conditioned upon the consummation of either of the debt financing contemplated by the Debt Commitment Letter or the remaining investment contemplated by the Investment Agreement, if we are unable to complete either of those financing transactions, the completion of our acquisition of Coherent may be delayed or not completed, in which case we would be in breach of our obligations under the merger agreement containing the terms of the acquisition.

The agreements that will govern indebtedness to be incurred or assumed in connection with our acquisition of Coherent are expected to contain various covenants that will impose restrictions on that may affect our ability to operate our businesses.

The agreements that will govern indebtedness to be incurred or assumed in connection with our acquisition of Coherent, including pursuant to the related debt financing contemplated by the Debt Commitment Letter, are expected to 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 definitive documentation governing certain of the facilities is expected to contain financial maintenance covenants that will require us to maintain a certain leverage ratio and an interest coverage ratio at the end of each fiscal quarter. Our ability to comply with these provisions may be affected by events beyond our control. Failure to comply with

36

these covenants could result in an event of default, which, if not cured or waived, could accelerate our repayment obligations under the applicable definitive documentation or under other debt agreements.

The significant additional indebtedness that we will incur in connection with our acquisition of Coherent could adversely affect us, including by decreasing our business flexibility, increasing our interest expense and causing our credit ratings to be downgraded.

As of June 30, 2021, we had consolidated indebtedness of approximately $1.4 billion. Our pro forma consolidated indebtedness as of June 30, 2021, after giving effect to our acquisition of Coherent and the anticipated incurrence and extinguishment of indebtedness in connection therewith, would have been approximately $5.1 billion. We will have substantially increased indebtedness following completion of the acquisition in comparison to what we have had on a recent historical basis, which could have the effect, among other things, of causing or accentuating the consequences described above under “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.”

In addition, our credit ratings impact the cost and availability of future borrowings and, accordingly, our cost of capital. Our ratings reflect each rating organization’s opinion of our financial strength, operating performance, and ability to meet our debt obligations. In connection with the anticipated debt financing contemplated by the Debt Commitment Letter, we expect that we will seek ratings of our indebtedness from leading rating organizations. There can be no assurance that we will achieve or maintain any particular rating in the future. In addition, there can be no assurance that the credit ratings of our existing debt will not be subject to a downgrade below investment grade. If a ratings downgrade were to occur or if we fail to maintain an investment grade rating, we could experience higher borrowing costs in the future and more restrictive debt covenants which could reduce profitability and diminish operational flexibility.

Integrating Coherent may be more difficult, costly or time-consuming than expected, and we may fail to realize the anticipated benefits of the acquisition, including our expected financial and operating performance following the consummation of the acquisition.

The success of our acquisition of Coherent will depend, in part, on our ability to realize the anticipated benefits and cost savings. To do so, we must successfully integrate Coherent in a manner that permits those benefits and cost savings to be realized. Our ability to successfully manage this expanded business will depend, in part, upon our ability to implement an effective integration of the two companies and manage a combined business with significantly larger size and scope with the associated increased costs and complexity. If we are not able to successfully achieve these objectives, or are not able to achieve these objectives on a timely basis, the anticipated benefits may not be realized fully or at all or may take longer to realize than expected. In addition, the actual cost savings could be less than anticipated.

We and Coherent have operated and, until the completion of the acquisition, must continue to operate independently. It is possible that the integration process could result in the loss of key employees, the disruption of each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect the companies’ ability to maintain relationships with clients, customers, suppliers and employees or to achieve the anticipated benefits and cost savings of the transaction. Integration efforts between the two companies also may divert management attention and resources. These integration matters could have an adverse effect on each company during this transition period and on us for an undetermined period after completion of the acquisition. All projections regarding the combined company’s business are, by their nature, estimates which are subject to risks and uncertainties. Business and financial measures of the combined company, including revenue, free cash flow, synergies and dividend yield, are uncertain and subject to change based on changes in assumptions underlying such measures or other changes in circumstances, many of which may be outside of our or Coherent’s control.

We and Coherent may have difficulty attracting, motivating and retaining executives and other employees in light of the pending acquisition.

Uncertainty about the effect of the pending acquisition on our and Coherent’s respective employees may have an adverse effect on us and Coherent. This uncertainty may impair our and Coherent’s ability to attract, retain and motivate personnel both before and after completion of the acquisition. We and Coherent are dependent on the experience and industry knowledge of our respective officers and other key employees to execute our business plans. The success of the acquisition will depend in part on our ability to retain the talents and dedication of key employees currently employed by Coherent. Employee retention may be particularly challenging during the pendency of the acquisition, as employees may feel uncertain about their future roles with us after completion of the acquisition. In addition, we and Coherent may have to provide additional compensation in order to retain employees.

If key employees terminate their employment with us or Coherent while the acquisition is pending, or with us after completion of the acquisition, our business activities may be adversely affected and our management’s attention may be diverted from successfully integrating Coherent to hiring suitable replacements, all of which may cause our business to suffer. In addition, we and Coherent may not be able to locate or retain suitable replacements for any key employees who leave either company.

37

Accordingly, no assurance can be given that we will be able to attract or retain key employees following the completion of the acquisition to the same extent that we or Coherent have been able to attract or retain employees in the past.

Regulatory approvals may not be received, may take longer than expected or may impose conditions that are not presently anticipated or that could have an adverse effect on us following the completion of the acquisition.

Before the acquisition may be completed, certain waiting periods must expire or terminate and applicable approvals must be obtained under certain antitrust, competition and foreign investment laws and regulations. In deciding whether to grant regulatory clearances and approvals, the relevant governmental entities may consider, among other things, the effect of the transaction on competition within their relevant jurisdiction. The terms and conditions of the approvals that are granted may impose requirements, limitations or costs or place restrictions on the conduct of our business. There can be no assurance that regulators will not impose conditions, terms, obligations or restrictions and that such conditions, terms, obligations or restrictions will not have the effect of delaying completion of the acquisition or imposing additional material costs on or materially limiting our revenues following the completion of the acquisition. In addition, we cannot provide assurance that any such conditions, terms, obligations or restrictions will not result in the delay or abandonment of the transaction.

Our pending acquisition of Coherent is subject to conditions, including certain conditions that may not be satisfied, and may not be completed on a timely basis, or at all. Failure to complete the acquisition could have material and adverse effects on us.

Our acquisition of Coherent is subject to a number of conditions, which make the completion and timing of the acquisition uncertain. In addition, the governing merger agreement may be terminated in certain circumstances. If the transaction is not completed on a timely basis or at all, our ongoing business may be adversely affected and, without realizing any of the benefits of having completed the acquisition, we will be subject to a number of risks, including the following:

•we will be required to pay certain costs relating to the transaction, whether or not the transaction is completed, such as legal, accounting, financial advisor and printing fees;

•under the merger agreement, we are subject to certain restrictions on the conduct of our business prior to completing the transaction, which may adversely affect our ability to execute certain of our business strategies;

•time and resources committed by our management team to matters relating to the transaction could otherwise have been devoted to pursuing other beneficial opportunities;

•the market price of our common stock could decline to the extent that the current market prices reflect a market assumption that the transaction will be completed; and

•depending on the circumstances in which the merger agreement is terminated, we may be required to pay a termination fee of $500.0 million, which may make it more difficult for us to pursue alternatives to the acquisition of Coherent.

In addition, if the transaction is not completed, we may experience negative reactions from financial markets and from our customers and employees. We could also be subject to litigation related to any failure to complete the transaction or to enforcement proceedings commenced against us to perform our obligations under the governing merger agreement. If the acquisition is not completed, we cannot assure that the risks described above will not materialize and will not adversely affect our business or financial results or the market price of our securities.

We have incurred, and will continue to incur, significant transaction-related costs in connection with our pending acquisition of Coherent.

We have incurred, and will continue to incur, substantial expenses in connection with the negotiation and completion of our pending acquisition of Coherent, as well as the costs and expenses of filing, printing and mailing a joint proxy statement/prospectus and various fees paid or to be paid to the SEC and other regulatory agencies in connection with the transaction. These fees and costs have been, and will continue to be, significant. In addition, we will incur significant costs with respect to the expected financing transactions relating to the cash portion of the merger consideration. If the transaction is not completed, we may have to recognize these expenses without realizing the expected benefits of the transaction.

We also expect to incur a number of non-recurring transaction-related costs associated with combining the operations of the two companies and achieving desired synergies. Additional unanticipated costs may be incurred in the integration of our business with Coherent’s business. There can be no assurance that the elimination of certain duplicative costs, as well as the realization of other efficiencies related to the integration of the two businesses, will offset the incremental transaction-related costs over time. Thus, any net benefit may not be achieved in the near term, the long term or at all.

The closing of our acquisition of Coherent may trigger change in control provisions in certain agreements to which Coherent is a party.

38

Certain agreements to which Coherent is a party contain change in control provisions that may be triggered when we complete our acquisition of Coherent. If we and Coherent are unable to negotiate waivers of those provisions, the counterparties may exercise their rights and remedies under the agreements, potentially terminating the agreements or seeking monetary damages. Even if we and Coherent are able to negotiate waivers, the counterparties may require a fee for such waivers or seek to renegotiate the agreements on terms less favorable to us.

We and Coherent each are subject to business uncertainties and contractual restrictions while our acquisition of Coherent is pending, which could adversely affect each of our and Coherent’s respective businesses and operations.

Under the terms of the merger agreement, we and Coherent are subject to certain restrictions on the conduct of our respective businesses prior to completing the transaction, which may adversely affect each party’s ability to execute certain of its business strategies. Such limitations could negatively affect each party’s businesses and operations prior to the completion of the transaction. Furthermore, the process of planning to integrate the two companies can divert management attention and resources and could ultimately have an adverse effect on us.

In connection with the transaction, parties with which we or Coherent do business may experience uncertainty associated with the transaction, including with respect to current or future business relationships with us, Coherent or the combined business. It is possible that some customers, suppliers and other persons with whom we or Coherent have a business relationship may delay or defer certain business decisions or might decide to seek to terminate, change or renegotiate their relationships with us or Coherent, as applicable, as a result of the transaction, which could negatively affect our or Coherent’s revenues, earnings and cash flows, as well as the market price of shares of our common stock, regardless of whether the transaction is completed.

Holders of our capital stock will have a reduced ownership and voting interest in us after the completion of our acquisition of Coherent and the expected remaining equity financing and therefore then will have less voting influence.

Each Coherent stockholder who receives shares of our common stock as merger consideration will become a shareholder of ours. We estimate that, upon completion of the acquisition, former Coherent stockholders collectively will own approximately 15%, our shareholders as of immediately prior to the completion of the transaction (excluding as a result of the expected remaining equity financing) will own approximately 71%, and BCPE will own approximately 14% of our outstanding shares of common stock (in each case, on an as-converted and fully diluted basis and without regard to the fact that immediately prior to the completion of the transaction, certain holders may own both our common stock and Coherent’s common stock). As a result, our shareholders will have less voting influence on us and may have less influence on our management and policies than they now have on us.

Shareholder litigation could prevent or delay the closing of our acquisition of Coherent or otherwise negatively impact our business and operations.

We may incur costs in connection with the defense or settlement of any shareholder lawsuits filed in connection with our pending acquisition of Coherent. Such litigation could have an adverse effect on our financial condition and results of operations and could prevent or delay the consummation of the transaction.

The issuance and sale of shares of our Series B-1 Preferred Stock has reduced, and the issuance and sale of our Series B-2 Preferred Stock will reduce, the relative voting power of holders of our other capital stock, will dilute the ownership of such holders and may adversely affect the market price of our securities.

On March 31, 2021, we issued 75,000 shares of Series B-1 Preferred Stock to BCPE. Those shares of Series B-1 Preferred Stock currently have voting rights and may vote as one class with our common stock, on an as-converted basis, subject to limited exceptions. Upon completion of our acquisition of Coherent, we will issue and sell 140,000 shares of Series B-2 Preferred Stock to BCPE. Those shares of Series B-2 Preferred Stock will have voting rights, voting as one class with our common stock and our Series B-1 Preferred Stock, on an as-converted basis, subject to limited exceptions. Therefore, the issuance and sale of Series B-1 Preferred Stock resulted, and the issuance and sale of Series B-2 Preferred Stock will result, in the immediate and substantial dilution to the ownership interests of the holders of our capital stock, including our common stock and our Mandatory Convertible Preferred Stock.

Any sales in the public market of our common stock issuable upon conversion of Series B Preferred Stock could adversely affect prevailing market prices of our other outstanding securities. Similarly, the perception that such sales might occur could have a material adverse effect on such market prices.

Our Series B-1 Preferred Stock have, and the Series B-2 Preferred Stock to be issued upon completion of our pending acquisition of Coherent will have rights, preferences and privileges that are not held by, and are preferential to, the rights of holders of our other outstanding capital stock.

39

In the event of any voluntary or involuntary liquidation, dissolution or winding up of our affairs, the holders of our Series B Preferred Stock are entitled to receive certain payments (i) prior to any amounts paid to holders of our common stock and each other class or series of our capital stock now existing or hereafter authorized, the terms of which do not expressly provide that such class or series ranks either (x) senior to the Series B Preferred Stock as to dividend rights or distribution rights upon such a liquidation event or (y) on parity with the Series B Preferred Stock as to dividend rights and distribution rights upon a such a liquidation event and (ii) on parity with our Mandatory Convertible Preferred Stock and each other class or series of our capital stock established in the future, the terms of which expressly provide that such class or series ranks on a parity basis with the Series B Preferred Stock as to dividend rights and distribution rights upon such a liquidation event. In addition, the holders of Series B Preferred Stock also have certain redemption, conversion and consent rights.

These provisions may make it more costly for a potential acquirer to engage in a business combination transaction with us. Provisions that have the effect of potentially discouraging, delaying or preventing such a transaction could limit the opportunity for our shareholders to receive a premium for their shares of our capital stock and could also affect the price that some investors are willing to pay for our capital stock. This could reduce the remaining amount of our assets, if any, available to distribute to holders of our capital stock.

Our obligations to the holders of Series B Preferred Stock could limit our ability to obtain additional financing or increase our borrowing costs, which could have an adverse effect on our financial condition. These preferential rights could also result in divergent interests between the holders of shares of our Series B Preferred Stock and other holders of our capital stock.

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 and, therefore, the interests of holders of our other capital stock.

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 and our Mandatory Convertible Preferred 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.

The Series B-1 Preferred Stock has, and the Series B-2 Preferred Stock will have, 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-1 Preferred Stock have, and the holders of Series B-2 Preferred Stock will 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 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 (as defined below) (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 Investment Agreement); and (5) effect any voluntary deregistration or delisting with Nasdaq 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 completion of either the issuance and sale of the Series B-1 Preferred Stock on March 31, 2021 (if the issuance and sale of the Series B-2 Preferred Stock has not occurred) or the issuance and sale of the Series B-2 Preferred Stock upon completion of our pending acquisition of Coherent, (i) authorize or issue any parity stock (as defined below) and (ii) pay any cash dividend on our common stock (other than ordinary dividends (as defined below)). 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 completion of either the issuance and sale of the Series B-1 Preferred Stock on March 31, 2021 (if the issuance and sale of the Series B-2 Preferred Stock has not occurred) or the issuance and sale of the Series B-2 Preferred Stock upon completion of our pending acquisition of Coherent, redeem,

40

repurchase or otherwise acquire (or make or declare any dividend or distribution in respect of) any junior stock (as defined below) (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 either the issuance and sale of the Series B-1 Preferred Stock on March 31, 2021 (if the issuance and sale of the Series B-2 Preferred Stock has not occurred) or the issuance and sale of the Series B-2 Preferred Stock upon completion of our pending acquisition of Coherent, 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 and our Mandatory Convertible Preferred Stock.

The market prices of our securities may decline in the future as a result of our acquisition of Coherent.

The market prices of our securities, including our common stock and our Mandatory Convertible Preferred Stock, may decline in the future as a result of our acquisition of Coherent for a number of reasons, including:

•the unsuccessful integration of Coherent (including for the reasons set forth above); and

•our failure to achieve the perceived benefits of the acquisition, including financial results, as rapidly as or to the extent anticipated by financial or industry analysts.

Many of these factors are beyond our control. As a consequence, holders of our capital stock, including our common stock and our Mandatory Convertible Preferred Stock, could lose the value of their investment in our capital stock.

We currently anticipate that our acquisition of Coherent will be accretive to earnings per share (on an adjusted earnings basis) in the second year after the completion of the acquisition. This expectation is based on preliminary estimates which may materially change. We also could encounter additional transaction-related costs or other factors such as the failure to realize all of the benefits anticipated in the acquisition. All of these factors could cause dilution to our earnings per share or decrease or delay the expected accretive effect of the acquisition and cause a decrease in the market prices of our securities, including our common stock and our Mandatory Convertible Preferred Stock.

Our future results will suffer if we do not effectively manage our expanded operations following the completion of our acquisition of Coherent.

Following the completion of our acquisition of Coherent, the size of our business will increase significantly beyond the current size of either our or Coherent’s current businesses. Our future success depends, in part, upon our ability to manage this expanded business, which may pose substantial challenges for management, including challenges related to the management and monitoring of new operations and associated increased costs and complexity. There can be no assurance that we will be successful or that we will realize the expected operating efficiencies, cost savings, revenue enhancements and other benefits currently anticipated from the acquisition.

We and Coherent face competition, which is expected to intensify after the closing of our acquisition of Coherent and which may reduce our market share and profits after consummation of the acquisition.

Competition in the industries in which we and Coherent operate is intense. Increased competition could hurt our and Coherent’s businesses, hinder our respective market share expansions and lead to pricing pressures that may adversely impact our respective margins and revenues. If we are unable to successfully compete following the completion of the acquisition, our business, prospects, liquidity, financial condition and results of operations could be materially and adversely affected.

Following the consummation of the acquisition, our competitive position could be weakened by strategic alliances or consolidation within our industries or the development of new technologies by competitors. Our ability to compete successfully will depend on how well we markets our products and services and on our ability to anticipate and respond to various competitive factors affecting our industries, including changes in customer preferences, and changes in the product offerings or pricing strategies of our competitors.

After the consummation of the acquisition, competition could materially adversely affect us in several ways, including (i) the loss of customers and market share, (ii) our need to lower prices or increase expenses to remain competitive and (iii) the loss of business relationships within our existing markets.

We expect to incur substantial expenses related to our acquisition of Coherent and the related integration.

41

We expect to incur substantial expenses in connection with our acquisition of Coherent and the related integration. There are a large number of processes, policies, procedures, operations, technologies and systems that may need to be integrated, including purchasing, accounting and finance, sales, payroll, pricing and benefits.

While we have assumed that a certain level of expenses will be incurred, there are many factors beyond our control that could affect the total amount or the timing of the integration expenses. Moreover, many of the expenses that will be incurred are, by their nature, difficult to estimate accurately. These expenses could, particularly in the near term, exceed the savings that we expect to achieve from the elimination of duplicative expenses and the realization of economies of scale and cost savings. These integration expenses likely will result in us taking significant charges against earnings following the completion of the acquisition, and the amount and timing of such charges are uncertain at present.

Following the consummation of our acquisition of Coherent, we will be bound by all of the obligations and liabilities of both companies.

Following the consummation of our acquisition of Coherent, we will become bound by all of the obligations and liabilities of Coherent in addition to our obligations and liabilities existing prior to the consummation of the acquisition. We cannot predict the financial condition of the combined company at the time of the completion of the acquisition or our ability to satisfy our obligations and liabilities following the completion of the acquisition.

Our acquisition of Coherent may result in a loss of suppliers and strategic alliances and may result in the termination of existing contracts.

Following the completion of our acquisition of Coherent, some of our suppliers or suppliers of Coherent may increase prices or may terminate or scale back their business relationship with us, or even become competitors of ours. We and Coherent have contracts with suppliers, vendors, and other business partners which may require us or Coherent to obtain consents from these other parties in connection with the pending transaction, which may not be obtained at all or on favorable terms. If supplier relationships or strategic alliances are adversely affected by our acquisition of Coherent, or if we, following the completion of the transaction, lose the benefits of our or Coherent’s contracts, our business and financial performance could suffer.

Risks Relating to Our Capital Stock

The trading prices for our securities have been volatile in the past and may be volatile in the future.

The trading prices for our common stock on the Nasdaq Global Select Market Composite varied between a high of $100.44 per share and a low of $36.04 per share in the fiscal year ended June 30, 2021. Likewise, the trading prices of our Mandatory Convertible Preferred Stock varied between a high of $407.35 per share and a low of $174.38 per share in the fiscal year ended June 30, 2021. The market prices of our securities could fluctuate significantly for many reasons, including the following:

•future announcements concerning us or our competitors;

•the overall performance of equity markets;

•the trading volume of our securities;

•additions or changes to our board of directors, management, or key personnel;

•regulatory actions (including, but not limited to, developments in international trade policy) and enforcement actions bearing on manufacturing, development, marketing, or sales;

•the commencement or outcome of litigation;

•reports and recommendations of analysts and whether or not we meet the milestones, metrics, and other expectations set forth in such reports;

•gaining or losing large customers;

•the introduction of new products or services and market acceptance of such products or services;

•the impact of any public health crisis on our business, financial condition, results of operations, or prospects or those of our customers and suppliers;

•the acquisition or loss of significant manufacturers, distributors, or suppliers or an inability to obtain sufficient quantities of materials needed to provide our services;

•the issuance of common stock or other securities (including shares of common stock issued upon conversion of any shares of Mandatory Convertible Preferred Stock or Series B Preferred Stock or upon conversion of our outstanding convertible notes);

•incurrence of indebtedness;

•quarterly variations in operating results;

•our ability to accurately forecast future performance;

42

•business acquisitions or divestitures, including developments relating to our pending acquisition of Coherent;

•fluctuations in the economy, political events, or general market conditions; and

•changes in our operating industry generally.

In addition, stock markets have experienced extreme price and volume fluctuations in recent years, including as a result of the effects of the COVID-19 pandemic. Moreover, these fluctuations frequently have been unrelated to the operating performance or underlying fundamentals of the affected companies. These broad market fluctuations may adversely affect the market price of our common stock. These fluctuations may be unrelated to our performance or out of our control, and could lead to securities class action litigation that could result in substantial expenses and diversion of management’s attention and corporate resources, any or all of which could adversely affect our business, financial condition, and results of operations.

We expect that the market price of our Mandatory Convertible Preferred Stock will be influenced by yield and interest rates in the capital markets, the time remaining to the mandatory conversion date applicable to the Mandatory Convertible Preferred Stock, our creditworthiness, and the occurrence of certain events affecting us that do not require an adjustment to the fixed conversion rates of the Mandatory Convertible Preferred Stock. Fluctuations in yield rates in particular may give rise to arbitrage opportunities based upon changes in the relative values of the Mandatory Convertible Preferred Stock and our common stock. Any such arbitrage could, in turn, affect the market prices of our common stock and the Mandatory Convertible Preferred Stock. The market price of our common stock could also be affected by possible sales of our common stock by investors who view the Mandatory Convertible Preferred Stock as a more attractive means of equity participation in us and by hedging or arbitrage trading activity that we expect to develop involving our common stock. This trading activity could, in turn, affect the market price of the Mandatory Convertible Preferred Stock.

Provisions in our Amended and Restated Articles of Incorporation (the “Articles of Incorporation”) and Amended and Restated Bylaws (the “Bylaws”) and the Pennsylvania Business Corporation Law (the “BCL”) 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 BCL 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 BCL 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 BCL, a “short-form” merger of II-VI 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.

43

Furthermore, the BCL 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 BCL expressly provides that directors do not violate their fiduciary duties solely by relying on “poison pills” or the anti-takeover provisions of the BCL. 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, certain rights of the holders of the Mandatory Convertible Preferred Stock could make it more difficult or more expensive for a third party to acquire us. For example, if any of certain fundamental changes were to occur on or prior to July 1, 2023, holders of the Mandatory Convertible Preferred Stock may have the right to convert their Mandatory Convertible Preferred Stock, in whole or in part, at an increased conversion rate and will also be entitled to receive a make-whole amount equal to the present value of all remaining dividend payments on their Mandatory Convertible Preferred Stock, as described in the applicable Statement with Respect to Shares governing the Mandatory Convertible Preferred Stock. Likewise, 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 Mandatory Convertible Preferred Stock and Series B Preferred Stock could increase the cost of acquiring us or otherwise discourage a third party from acquiring us or removing incumbent management.

Because we do not currently intend to pay dividends on our common stock, holders will benefit from an investment in our common stock only if it appreciates in value and by the intended anti-dilution actions of our share-buyback program.

We have never declared nor paid dividends on our common stock and do not expect to pay cash dividends on our common stock in the foreseeable future. We currently anticipate that we will retain future earnings to support operations and to finance the development of our business. As a result, the success of an investment in our common stock will depend entirely upon future appreciation in its value. There is no guarantee that our common stock will maintain its value or appreciate in value.

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. If the terms of the Credit Agreement restrict our ability to pay cash dividends on the Mandatory Convertible Preferred Stock, we will pay any dividends declared by our board of directors (or an authorized committee thereof) on the Mandatory Convertible Preferred Stock in the form of shares of common stock. In addition, credit facilities, indentures, or other financing agreements that we enter into in the future may contain provisions that restrict or prohibit our ability to pay cash dividends on our capital stock.

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. Even if we are permitted under our contractual obligations and Pennsylvania law to pay cash dividends on the Mandatory Convertible Preferred Stock, we may not have sufficient cash to pay cash dividends on the Mandatory Convertible Preferred Stock.

Trading in preferred stock that we have issued may adversely affect the market price of our common stock.

The market price of our common stock is likely to be influenced by the Mandatory Convertible Preferred Stock and, to the extent that markets develop when applicable trading limitations no longer apply, our Series B Preferred Stock. For example, the market price of our common stock could become more volatile and could depress possible sales of our common stock to shareholders who view the Mandatory Convertible Preferred Stock or Series B Preferred Stock as more attractive means of equity participation in us than owning shares of our common stock.

Our common stock is subordinate to our existing and future indebtedness; the Mandatory Convertible Preferred Stock and Series B Preferred Stock; and any other preferred stock we may issue in the future. Our Mandatory Convertible Preferred Stock and Series B Preferred Stock rank 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.

44

Our common stock ranks junior to our Mandatory Convertible Preferred Stock and 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 Mandatory Convertible Preferred Stock and 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 Mandatory Convertible Preferred Stock and 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 Mandatory Convertible Preferred Stock and Series B Preferred Stock only after all of our consolidated liabilities have been paid. In addition, the Mandatory Convertible Preferred Stock and Series B Preferred Stock rank 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 Mandatory Convertible Preferred Stock and 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 power, 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.

Reports published by securities or industry analysts, freelance bloggers and credit rating agencies, including projections in those reports that exceed our actual results, could adversely affect our share price and trading volume.

Research analysts and freelance bloggers publish their own quarterly projections regarding our operating results. These projections may vary widely from one another and may not accurately predict the results we actually achieve. Our share price may decline if we fail to meet securities research analysts’ projections. Similarly, if one or more of the analysts who cover us change their recommendations regarding our common stock or publish inaccurate or unfavorable research about our business, our share price could decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, our share price or trading volume could decline.

Regulatory actions may adversely affect the trading price and liquidity of the Mandatory Convertible Preferred Stock.

Holders of Mandatory Convertible Preferred Stock who employ, or seek to employ, a convertible arbitrage strategy with respect to the Mandatory Convertible Preferred Stock may be adversely impacted by regulatory developments that may limit or restrict such a strategy. The SEC and other regulatory and self-regulatory authorities have implemented various rules and may adopt additional rules in the future that restrict and otherwise regulate short selling, over-the-counter swaps, and security-based swaps, which restrictions and regulations may adversely affect the ability of investors in, or potential purchasers of, the Mandatory Convertible Preferred Stock to conduct a convertible arbitrage strategy with respect to the Mandatory Convertible Preferred Stock. This could, in turn, adversely affect the trading price and liquidity of the Mandatory Convertible Preferred Stock.

Holders of Mandatory Convertible Preferred Stock have no voting rights with respect to the Mandatory Convertible Preferred Stock, except under limited circumstances.

Holders of Mandatory Convertible Preferred Stock have no voting rights with respect to the Mandatory Convertible Preferred Stock, except with respect to certain amendments to the terms of the Mandatory Convertible Preferred Stock, in the case of certain dividend arrearages, in certain other limited circumstances, and except as specifically required by applicable Pennsylvania law or by our amended and restated Articles of Incorporation. Holders of Mandatory Convertible Preferred Stock have no right to vote for any members of our board of directors, except in the case of certain dividend arrearages.

45

If dividends on any Mandatory Convertible Preferred Stock have not been declared and paid for the equivalent of six or more dividend periods (including, for the avoidance of doubt, the dividend period beginning on, and including, the initial issue date of the Mandatory Convertible Preferred Stock and ending on, but excluding, October 1, 2020), whether or not for consecutive dividend periods, the holders of such Mandatory Convertible Preferred Stock, voting together as a single class with holders of all other series of preferred stock ranking equally with the Mandatory Convertible Preferred Stock and having similar voting rights, will be entitled at our next special or annual meeting of shareholders to vote for the election of a total of two additional members of our board of directors, subject to certain limitations.

We depend on our subsidiaries for cash to fund our operations and expenses, including future dividend payments with respect to our outstanding preferred stock.

A significant portion of our operations is conducted through our subsidiaries, and our ability to generate cash to meet our debt service obligations or to make future dividend payments with respect to the Mandatory Convertible Preferred Stock and, to the extent we elect to make such payments in cash, our Series B Preferred Stock is highly dependent on the earnings and the receipt of funds from our subsidiaries. Our subsidiaries are separate legal entities that have no obligation to make any funds available to us, whether by dividends, loans, or other payments.

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 Nasdaq Global Select Market under the symbol “IIVI.” As of August 16, 2021, there were approximately 806 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 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 6% of the liquidation preference of $200.00 per share. The Company may pay declared dividends on the Mandatory Convertible Preferred Stock in cash or, subject to certain limitations, in shares of our common stock or in any combination of cash and shares of our common stock on January 1, April 1, July 1 and October 1 of each year, commencing on October 1, 2020 and ending on, and including, July 1, 2023.

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 II-VI defaults on 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.

ISSUER PURCHASES OF EQUITY SECURITIES

In August 2017, in conjunction with the Company’s offering and sale of our 0.25% outstanding convertible senior notes, the Company’s Board of Directors authorized the Company to purchase up to $50 million of its common stock with a portion of the net proceeds received from the offering and sale of those convertible notes. The shares that were purchased by the Company pursuant to this authorization were retained as treasury stock and are available for general corporate purposes. The Company purchased 1,414,900 shares of its common stock for approximately $50 million pursuant to this authorization.

In August 2014, the Company’s Board of Directors authorized the Company to purchase up to $50 million of its common stock through a share repurchase program (the “Program”) that calls for shares to be purchased in the open market or in private transactions from time to time. The Program has no expiration and may be suspended or discontinued at any time. Shares purchased by the Company are retained as treasury stock and available for general corporate purposes. The Company did not repurchase shares pursuant to this Program during the fiscal year ended June 30, 2021. During the fiscal year ended June 30, 2020, the Company purchased 50,000 shares of its common stock for $2 million under this program. As of June 30, 2021, the Company has cumulatively purchased 1,416,587 shares of its common stock pursuant to the Program for approximately $22 million. The dollar value of shares as of June 30, 2021 that may yet be purchased under the Program is approximately $28 million.

Item 7.        MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Forward-Looking Statements

Certain statements contained in this Management’s Discussion and Analysis of Financial Condition and Results of Operations ("Management Discussion and Analysis") are forward-looking statements as defined by Section 21E of the Securities Exchange Act of 1934, as amended, including statements regarding projected growth rates, markets, product development, financial position, capital expenditures and foreign currency exposure. Forward-looking statements are also identified by words such as “expects,” “anticipates,” “believes,” “intends,” “plans,” “projects” or similar expressions.

Although our management considers these expectations and assumptions to have a reasonable basis, there can be no assurance that management’s expectations, beliefs or projections as expressed in the forward-looking statements will actually occur or prove to be correct. In addition to general industry and global economic conditions, factors that could cause actual results to differ materially from those discussed in the forward-looking statements in this Annual Report on Form 10-K include, but are not limited to: (i) the failure of any one or more of the assumptions stated above to prove to be correct; and (ii) the risks relating to forward-looking statements and other “Risk Factors” discussed herein at Item 1A. The Company disclaims any obligation to update information contained in these forward-looking statements whether as a result of new information, future events or developments, or otherwise.

50

In addition, we operate in a highly competitive and rapidly changing environment; new risk factors can arise, and it is not possible for management to anticipate all such risk factors, or to assess the impact of all such risk factors on our business or the extent to which any individual risk factor, or combination of risk factors, 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 are based only on information currently available to us and speak only as of the date of this Report. We do not assume any obligation, and do not intend to, update any forward-looking statements, whether as a result of new information, future developments or otherwise, except as may be required by the securities laws. Investors should, however, consult any further disclosures of a forward-looking nature that the Company may make in its subsequent Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, or other disclosures filed with or furnished to the SEC.

Investors should also be aware that, while the Company does communicate with securities analysts from time to time, such communications are conducted in accordance with applicable securities laws. Investors should not assume that the Company agrees with any statement or report issued by any analyst irrespective of the content of the statement or report.

The Company may elect to change the way in which the Company operates or is organized in the future to enable the most efficient implementation of our strategy.

Pending Acquisition of Coherent, Inc.

On March 25, 2021, II-VI, Coherent, Inc. (“Coherent”) and Watson Merger Sub Inc., a wholly owned subsidiary of II-VI (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”). Pursuant to the terms of the Merger Agreement, and subject to the conditions set forth therein, Merger Sub will be merged with and into Coherent, and Coherent will continue as the surviving corporation in the merger and wholly owned subsidiary of II-VI (the “Merger”).

Pursuant to the terms of the Merger Agreement, and subject to the conditions set forth therein, at the effective time of the Merger (the “Effective Time”), each share of common stock of Coherent (the “Coherent Common Stock”) issued and outstanding immediately prior to the Effective Time will be canceled and extinguished and automatically converted into the right to receive the following consideration (collectively, the “Merger Consideration”): (A) $220.00 in cash, without interest (the “Cash Consideration”), and (B) 0.91 of a validly issued, fully paid and nonassessable share of our common stock of II-VI.

Pursuant to the terms of the Merger Agreement, each Coherent restricted stock unit award (a “Coherent RSU”), other than Director RSUs (as defined below), outstanding immediately prior to the Effective Time will be automatically converted into time-based restricted stock units denominated in shares of II-VI Common Stock entitling the holder to receive, upon settlement, a number of shares of II-VI Common Stock equal to the number of shares of Coherent Common Stock subject to the Coherent RSU multiplied by the sum of (A) 0.91, and (B) the quotient obtained by dividing the Cash Consideration by the volume weighted average price of a share of II-VI Common Stock for a 10 trading day period ending prior to the closing of the Merger

51

(the “Closing”). For Coherent RSUs subject to performance-based vesting conditions and metrics, the number of shares of II-VI Common Stock subject to the converted Coherent RSUs will be determined after giving effect to the Coherent Board of Directors’ determination of the number of Coherent RSUs earned, based on the greater of the target or actual level of achievement of such goals or metrics immediately prior to the Effective Time.

The converted Coherent RSUs generally will be subject to the same terms and conditions that applied to the awards immediately prior to the Effective Time, provided that any Coherent RSUs subject to performance-based vesting conditions will be subject solely to time- and service-based vesting. Each Coherent RSU that is outstanding as of the date of the Merger Agreement and as of immediately prior to the Effective Time will be entitled to certain vesting acceleration benefits.

Each Coherent RSU granted to a non-employee member of Coherent’s Board of Directors (“Director RSUs”) (whether or not vested) that is outstanding immediately prior to the Effective Time will automatically vest in full and be canceled and converted into the right to receive the Merger Consideration as if such Director RSU had been settled in shares of Coherent Common Stock immediately prior to the Effective Time.

The Boards of Directors of II-VI and Coherent unanimously approved the Merger and the Merger Agreement. II-VI filed with the SEC a registration statement on Form S-4 relating to the Merger, and the SEC declared that registration statement to be effective on May 6, 2021. Shareholders of II-VI and stockholders of Coherent voted to approve proposals related to the Merger at special meetings held on June 24, 2021 by the respective companies.

The completion of the Merger is subject to the satisfaction or waiver of certain additional customary closing conditions, including review and approval of the Merger by the State Administration for Market Regulation in China. Subject to the satisfaction or waiver of each of the closing conditions, II-VI expects that the Merger will be completed by the end of the first calendar quarter of 2022. However, it is possible that factors outside the control of both companies could result in the Merger being completed at a different time or not at all.

In connection with entering into the Merger Agreement, II-VI has obtained a fully underwritten financing commitment pursuant to a commitment letter (the “Commitment Letter”), dated as of March 25, 2021, as further amended and restated on April 21, 2021, with JPMorgan Chase Bank, N.A., Citigroup Global Markets Inc., MUFG Bank, Ltd., MUFG Securities Americas Inc., PNC Capital Markets LLC, PNC Bank, National Association, HSBC Securities (USA) Inc., HSBC Bank USA, National Association, Citizens Bank, N.A., Mizuho Bank, Ltd., BMO Capital Markets Corp., Bank of Montreal, TD Securities (USA) LLC, The Toronto-Dominion Bank, New York Branch, TD Bank, N.A. and First National Bank of Pennsylvania (collectively, the “Commitment Parties”) pursuant to which the Commitment Parties have committed to provide up to $5.1 billion in debt financing ( the “Debt Financing”). The obligation of the Commitment Parties to provide the Debt Financing provided for in the Commitment Letter is subject to a number of customary conditions.

In connection with entering into the Merger Agreement, II-VI entered into an Amended and Restated Investment Agreement, dated as of as of March 30, 2021, the “Investment Agreement”), with BCPE Watson (DE) SPV, LP, an affiliate of Bain Capital Private Equity, LP (the “Investor”). Pursuant to the terms of the Investment Agreement, on March 31, 2021, II-VI issued, sold, and delivered to the Investor 75,000 shares of a new Series B-1 Convertible Preferred Stock of the Company (“II-VI Series B-1 Convertible Preferred Stock”) for $10,000 per share (the “Equity Per Share Price”), resulting in an aggregate purchase price of $750 million. Subject to the terms and conditions of the Investment Agreement, among other things, the Company and the Investor also agreed that the company would issue, sell and deliver to the Investor:

•105,000 shares of a new Series B-2 Convertible Preferred Stock of the Company (“II-VI Series B-2 Convertible Preferred Stock”) for a purchase price per share equal to the Equity Per Share Price, resulting in an aggregate purchase price of $1.1 billion, immediately prior to Closing; and

•immediately prior to Closing, the company will receive up to an additional 35,000 shares of II-VI Series B-2 Convertible Preferred Stock (the "Upsize Shares") for a purchase price per share equal to the Equity Per Share Price, resulting in an aggregate maximum purchase price for the Upsize Shares of $350 million. This was agreed on June 8, 2021 of its agreement to purchase the Upsize Shares from the Company immediately prior to the Closing, increasing the investor’s total equity commitment to II-VI pursuant to the Investment Agreement to $2.2 billion.

The expenses associated with the pending acquisition for the year ended June 30, 2021, have not been allocated to an Operating Segment, and are presented in the Unallocated and Other within this Annual Report on Form 10-K.

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.

Series A Preferred Stock

As described in Note 11. Equity and Redeemable Preferred Stock, of the Notes to our Consolidated Financial Statements, on July 7, 2020, the Company issued shares of Series A Mandatory Convertible Preferred Stock. Upon conversion, on the mandatory conversion date, each outstanding share of Series A Mandatory Convertible Preferred Stock, unless previously converted, will automatically convert into a number of shares of the Company’s common stock determined based on the market value of the Company’s common stock on the mandatory conversion date, defined as July 1, 2023.

The accounting for the issuance of the Series A Mandatory Convertible Preferred Stock involved significant estimation in approximating the future market value of the Company’s common stock on the mandatory conversion date, which was used to determine whether the Series A Mandatory Convertible Preferred Stock should be classified within shareholders’ equity on the consolidated balance sheet as well as the whether the Preferred Stock should be classified as a participating security.

Management estimated the future market value of its common stock on the mandatory conversion date, through development of a Monte Carlo simulation model. A sensitivity analysis was also performed to confirm the reasonableness of the assumptions, which included volatility and cost of equity. The Company bases its estimates and assumptions on historical experience and on various other factors that it believes to be reasonable under the circumstances. Actual results could differ from those estimates.

Goodwill

The Company tests 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 2021, 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 of June 30, 2021, no reporting units are at risk for impairment. 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 both of our reporting units, our determination of future fair value might not support the carrying amount of one or both of our reporting units, and the related goodwill would need to be impaired.

53

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.

COVID-19 Update

On March 11, 2020, the World Health Organization designated the novel coronavirus disease known as COVID-19 as a global pandemic. In response to the global spread of COVID-19, governments at various levels have implemented unprecedented response measures. Overall, the COVID-19 pandemic has significantly curtailed global economic activity and caused significant volatility and disruption in global financial markets. Certain of the measures taken in response to the COVID-19 pandemic have adversely affected, and could in the future materially adversely impact, our business, results of operations, financial condition and stock price. In particular, the COVID-19 pandemic continues to have a significant impact on global markets due to resulting supply chain and production disruptions, workforce and travel restrictions.

Our focus has been on the protection of the health and safety of our employees and business partners. In our facilities, we have deployed new safety measures, including guidance to employees on matters such as effective hygiene and disinfection, social distancing, limited and remote access working where feasible and use of protective equipment. We also are prioritizing efforts to understand and support the changing business needs of our customers and suppliers in light of restrictions that are applicable to them.

At this time, we believe that our existing balances of cash and cash equivalents, along with our existing committed borrowing availability and other short-term liquidity arrangements, will be sufficient to satisfy our working capital needs, make necessary capital asset purchases and debt repayments and meet other liquidity requirements associated with our existing operations. Likewise, our current estimates indicate that we will remain in compliance with financial covenants applicable under our debt arrangements.

The full extent of the impact of the COVID-19 pandemic and the related responses on our operational and financial performance is currently uncertain and will depend on many factors outside our control, including, without limitation, the duration and severity of the pandemic, the imposition of protective public safety measures, and the impact of the pandemic on the global economy as a whole and, in particular, demand for our products. Due to these uncertainties, we cannot reasonably estimate the related impact on us at this time.

For additional information regarding the risks that we face as a result of the COVID-19 pandemic, please see Item 1A, Risk Factors, in Part I of this Form 10-K. Further, to the extent the COVID-19 pandemic adversely affects our business and financial results, it also may have the effect of heightening many of the other risks described in the risk factors in Item 1A of this Form 10-K.

Consolidated

Revenues. Revenues for the year ended June 30, 2021 increased 30% to $3,106 million, compared to $2,380 million for the prior fiscal year. Revenue for 2021 was a record with growth across all end markets compared to the same period last fiscal year. Communications, our largest vertical, grew 30% compared to the same period last year. This growth was due to a full year of Finisar revenue, strong demand across transceivers, including 200/400G products, as well as other optical communications products. The strong demand for our 3D sensing products drove 118% growth in revenue for Consumer Electronics. Life Sciences grew 65%, driven by demand for our filters, optics and thermo-electric coolers for COVID-19 related PCR testing and sequencing instrumentation. Our Industrial business grew 11% compared to the same period last year, due to strong growth in both "CO 2" and one micron laser components.

Gross margin. Gross margin for the year ended June 30, 2021 was $1,216 million, or 39%, of total revenues, compared to $820 million, or 34% of total revenues, for the same period last fiscal year. Gross margin as a percentage of revenues increased 470 basis points compared to the prior fiscal year. Gross margin was negatively impacted in the prior year by the effects of purchase accounting on inventory, an increased value of $87.7 million related to the fair value adjustment of the acquired Finisar inventory.

Internal research and development. Company-funded internal research and development (“IR&D”) expenses for the fiscal year ended June 30, 2021 were $330 million, or 11% of revenues, compared to $339 million, or 14%. of revenues, last fiscal year. The IR&D expenses are primarily related to the Company continuing to invest in new products and processes across all its businesses including investments in high speed datacom and telecom transceivers, high speed integrated circuits (ICs), 5G technology, 3D sensing, indium phosphide semiconductor lasers, gallium arsenide semiconductor lasers, silicon carbide semiconductor technology, and other emerging market trends. 

55

Selling, general and administrative. Selling, general and administrative (“SG&A”) expenses for the year ended June 30, 2021 were $484 million, or 16% of revenues, compared to $441 million, or 19% of revenues, last fiscal year. The Company incurred transaction and integration costs relating to the acquisitions of Finisar, Ascatron and Innovion, the pending acquisition of Coherent, increased stock compensation due to the increased II-VI stock price, as well as the SG&A from the operations of Ascatron and Innovion.

Interest and other, net. Interest and other, net for the year ended June 30, 2021 was expense of $50 million compared to expense of $103 million last fiscal year, or a decrease of $53 million year over year.  Interest and other, net primarily includes $60 million for interest expense on borrowings, and $6 million of foreign currency losses. The decrease compared to prior fiscal year is driven by lower levels of debt outstanding, due to the Term Loan B being repaid with funds from the July 2020 equity raise, as well as gains of $7 million and $11 million recognized in relation to the Innovion acquisition and the Preferred Series B forward sale agreement, respectively. These gains were offset by $25 million of debt issuance costs recognized in conjunction with the repayment of the Company's Term Loan B Facility in fiscal 2021.

There were foreign currency losses of $6 million for the year ended June 30, 2021 due to the volatility in the foreign exchange market, compared to $8 million of losses for the year ended June 30,2020.

Income taxes. The Company’s year-to-date effective income tax rate at June 30, 2021 was 16%, compared to an effective tax rate of (5)% last fiscal year. The current fiscal year’s effective tax rate was lower than statutory rates because of favorable research and development incentives in certain jurisdictions and stock option exercise benefits from the strong II-VI stock price.

Segment Reporting

Revenues and operating income for the Company’s reportable segments are discussed below. Operating income differs from income from operations in that operating income excludes certain expenses included in interest and other (net), as reported. Management believes operating income 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 15. 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 operating income to net earnings, which is incorporated herein by reference.

Photonic Solutions ($ in millions)

	Year Ended June 30,				% Increase/(Decrease)
	2021		2020
Revenues	$	2,038	$	1,537	33	%
Operating income	$	208	$	50	316	%

The above operating results for the year ended June 30, 2021 include the Company’s acquisition of Finisar in September 2019.

Revenues for the year ended June 30, 2021 for Photonic Solutions increased 33% to $2,038 million, compared to $1,537 million for last fiscal year. The largest driver of the increase is the inclusion of four full fiscal quarters of revenue from Finisar compared to 6 days and three quarters of revenue in the prior year. Our transceiver business grew across all product lines including the 200G and 400G modules.

Operating income for the year ended June 30, 2021 for Photonic Solutions increased 316% to $208 million, compared to an operating income of $50 million last fiscal year. The drivers of the increased operating income were higher sales volume, and improved operating performance and the absence of costs related to purchase accounting that were present in fiscal year 2020.

Compound Semiconductors ($ in millions)

	Year Ended June 30,				% Increase/(Decrease)
	2021		2020
Revenues	$	1,068	$	821	30	%
Operating income	$	221	$	62	255	%

The above operating results for the year ended June 30, 2021 include the Company’s acquisition of Finisar in September 2019.

Revenues for the fiscal year ended June 30, 2021 for Compound Semiconductors increased 30% to $1,068 million, compared to revenues of $821 million last fiscal year. The increase in revenues during the current fiscal year was primarily driven by over a 100% increase in VCSEL product shipments addressing the 3D sensing consumer market, and increased revenues to customers in all of our other markets with significant growth in our Life Sciences business.

Operating income for the fiscal year ended June 30, 2021 for Compound Semiconductors increased 255% to $221 million, compared to operating income of $62 million last fiscal year. The increase in operating income during the current fiscal year was primarily driven by product mix and improved absorption of operating costs due to higher volumes and shipping 3D sensing products. In addition, the expenses associated with the fair value inventory write-up and other related acquisition expenses for Finisar did not repeat in the current year.

Consolidated

Revenues. Revenues for the year ended June 30, 2020 increased 75% to $2,380 million, compared to $1,362 million for fiscal year 2019. The increase in revenues was primarily attributed to the acquisition of Finisar, which contributed $938 million of revenues for the fiscal year ended June 30, 2020. In addition to the acquisition of Finisar, the increase in revenues within Photonic Solutions was driven by increased demand from customers in the optical communication market, ROADM and other optical communication products addressing the growing deployment of 5G optical networks. Compound Semiconductors recorded a 13% revenue increase during fiscal year 2020, which in addition to revenues from Finisar, was driven by strengthening demand for SiC substrate products addressing RF electronics and high-power switching systems. This segment also realized increased revenues from its aerospace and defense products addressing strengthening demand from customers in the intelligence, surveillance and reconnaissance markets.

Gross margin. Gross margin for the year ended June 30, 2020 was $820 million, or 34%, of total revenues, compared to $521 million, or 38% of total revenues, for the same period fiscal year 2019. Gross margin as a percentage of revenues decreased 380 basis points compared to fiscal year 2019 despite the 75% increase in revenues during this same fiscal year. Gross margin was negatively impacted by additional cost of goods sold of $88 million related to the fair value adjustment of the acquired Finisar inventory, and as the result of product mix relating to Finisar's Transceiver product line which has a lower gross margin profile than the Company's historical margins.

Internal research and development. Company-funded IR&D expenses for the fiscal year ended June 30, 2020 were $339 million, or 14% of revenues, compared to $139 million, or 10% of revenues, fiscal year 2019. The increase in IR&D expenses was primarily due to the Company continuing to invest in new products and processes across all its businesses including investments in 5G technology, 3D Sensing, indium phosphide, LIDAR and other emerging market trends.

Selling, general and administrative. SG&A expenses for the year ended June 30, 2020 were $441 million, or 19% of revenues, compared to $234 million, or 17% of revenues, fiscal year 2019. The increase in SG&A was primarily the result of transaction costs incurred relating to the acquisition of Finisar as well as the SG&A from the Finisar acquisition.

Interest and other, net. Interest and other, net for the year ended June 30, 2020 was expense of $103 million compared to expense of $20 million fiscal year 2019. Interest and other, net primarily includes $89 million for interest expense on borrowings, $14 million of foreign currency losses, and $3 million of equity earnings from unconsolidated investments. Interest expense increased due to the higher levels of outstanding debt incurred in conjunction with the acquisition of Finisar. In addition, the Company expensed $4 million of debt extinguishment costs during fiscal year 2020 and recorded a $5 million impairment charge for an unconsolidated investment as its carrying value was determined to be unrecoverable.

Income taxes. The Company’s year-to-date effective income tax rate at June 30, 2020 was a (5)% benefit, compared to an effective tax rate of 17% fiscal year 2019. Fiscal year 2020’s effective tax rate was negatively impacted by the U.S. enacted tax legislation related to GILTI partially offset by research and development incentives in certain jurisdictions.

Photonic Solutions ($ in millions)

	Year Ended June 30,				% Increase
	2020		2019
Revenues	$	1,537	$	639	141	%
Operating income	$	50	$	82	(39)	%

The above operating results for the year ended June 30, 2020 include the Company’s acquisitions of Finisar in September 2019.

Revenues for the year ended June 30, 2020 for Photonic Solutions increased 141% to $1,537 million, compared to $639 million for fiscal year 2019. Included in revenue for fiscal year 2020 was $904 million of revenues from the Finisar acquisition. Exclusive of the acquisition, the increase in revenues was attributed to increased demand of our 5G optical networks driven by the China broadband initiative.

Operating income for the year ended June 30, 2020 for Photonic Solutions decreased 39% to $50 million, compared to an operating income of $82 million for fiscal year 2019. The decrease in operating income was primarily due to acquisition related expenses related to amortization expense on acquired intangible assets and the expensing of acquired inventory fair value step-up partially offset by incremental margin realized on increased revenues during the year.

	Year Ended June 30,				% Increase
	2020		2019
Revenues	$	821	$	724	13	%
Operating income	$	62	$	82	(24)	%

The above operating results for the year ended June 30, 2020 include the Company's acquisition of Finisar in September 2019.

Revenues for the fiscal year ended June 30, 2020 for Compound Semiconductors increased 13% to $821 million, compared to revenues of $724 million for fiscal year 2019. The increase in revenues during fiscal year 2020 was primarily driven by increased VCSEL product shipments addressing the 3D Sensing consumer market, and increased revenues to customers in the aerospace and defense market.

Operating income for the fiscal year ended June 30, 2020 for Compound Semiconductors decreased 24% to $62 million, compared to operating income of $82 million for fiscal year 2019.

Net cash provided by operating activities:

Net cash provided by operating activities was $574 million during the current fiscal year ended June 30, 2021 compared to $297 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, 2021 compared to the same period last fiscal year was primarily driven by additional net earnings of $277 million in the year ended June 30, 2021 compared to the same period last fiscal year.

Net cash provided by operating activities was $297 million and $179 million for the fiscal years ended June 30, 2020 and 2019, respectively. The increase in cash flows provided by operating activities during fiscal year ended June 30, 2020 compared to fiscal year ended June 30, 2019 was primarily driven by increased non-cash charges for depreciation and amortization as well as overall favorable changes in working capital offset by lower earnings as a result of acquisition-related expenses incurred for the acquisition of Finisar. Acquisition-related expenses include transaction expenses, expensing of the fair value write-up of acquired inventory and increased depreciation and amortization charges for acquired property, plant and equipment and intangible assets.

Net cash used in investing activities:

Net cash used in investing activities was $173 million for the fiscal year ended June 30, 2021, compared to net cash used of $1,179 million for the same period last fiscal year.

Net cash used in investing activities was $1,179 million and $224 million for the fiscal years ended June 30, 2020 and 2019, respectively. Net cash used in investing activities during the fiscal year ended June 30, 2020 primarily included $1,037 million for net cash paid for the acquisition of Finisar, and $137 million of cash paid for property, plant and equipment to increase capacity to meet the growing demand for the Company’s product portfolio.

Net cash provided by financing activities:

Net cash provided by financing activities was $676 million for the fiscal year ended June 30, 2021, compared to net cash provided by financing activities of $1,174 million for the same period last fiscal year. Net cash provided by financing activities was primarily impacted by $1,611 million of net proceeds from the Company's underwritten public offering in July 2020 as well as the issuance of the Series B Preferred Stock in March 2021, offset by cash used to repay borrowings of $926 million.

Net cash provided by financing activities was $1,174 million for the year ended June 30, 2020 compared to net cash provided by financing activities of $5 million for the year ended June 30, 2019.

The credit agreement governing the Senior Credit Facilities (the "Credit Agreement") provides for senior secured financing of $2.4 billion in the aggregate, consisting of

(i)Aggregate principal amount of $1,255 million for a five-year senior secured first-lien term A loan facility (the “Term A Facility”),

(ii)Aggregate principal amount of $720 million for a seven-year senior secured term B loan facility (the “Term B Facility” and together with the Term A Facility, the “Term Loan Facilities”), which was repaid in full during the quarter ended September 30, 2020, and

60

(iii)Aggregate principal amount of $450 million for a five-year senior secured first-lien revolving credit facility (the “Revolving Credit Facility” and together with the Term Loan Facilities, the “Senior Credit Facilities”).

The Credit Agreement also provides for a letter of credit sub-facility not to exceed $25 million and a swing loan sub-facility initially not to exceed $20 million.

The Term B Facility was repaid in full by the Company subsequent to the public offerings that closed on July 7, 2020. In conjunction with the repayment, the Company paid $1 million in associated interest and expensed $25 million of debt issuance costs related to the Term B Facility.

The Company is obligated to repay the outstanding principal amount of the Term A Facility in quarterly installments equal to 1.25% of the initial aggregate principal amount of the Term A Facility, with the remaining outstanding balance due and payable on the fifth anniversary of September 24, 2019 (the "Finisar Closing Date").

The Company’s obligations under the Senior Credit Facilities are guaranteed by each of the Company’s existing or future direct and indirect domestic subsidiaries (collectively, the “Guarantors”). Borrowings under the Senior Credit Facilities are collateralized by a first priority lien in substantially all of the assets of the Company and the Guarantors, except that no real property is collateral under the Senior Credit Facilities.

All amounts outstanding under the Senior Credit Facilities become due and payable 120 days prior to the maturity of the Company’s currently outstanding 0.25% Convertible Senior Notes due 2022 (the “II-VI Notes”) if (i) the II-VI Notes remain outstanding, and (ii) the Company has insufficient cash and borrowing availability to repay the principal amount of the II-VI Notes.

Amounts outstanding under the Senior Credit Facilities bear interest at a rate per annum equal to an applicable margin over a eurocurrency rate or an applicable margin over a base rate determined by reference to the highest of (a) the federal funds rate plus 0.50%, (b) Bank of America, N.A.’s prime rate and (c) a eurocurrency rate plus 1.00%, in each case as calculated in accordance with the terms of the Credit Agreement. The applicable interest rate would increase under certain circumstances relating to events of default.  The Company has entered into an interest rate swap contract to hedge its exposure to interest rate risk on its variable rate borrowings under the Senior Credit Facilities.  Refer to Note 15 for further information regarding this interest rate swap.

The Credit Agreement contains customary affirmative and negative covenants with respect to the Senior Credit Facilities, including limitations with respect to liens, investments, indebtedness, dividends, mergers and acquisitions, dispositions of assets and transactions with affiliates. The Company will be obligated to maintain a consolidated interest coverage ratio (as calculated in accordance with the terms of the Credit Agreement) as of the end of each fiscal quarter of not less than 3.00 to 1.00. The Company will be obligated to maintain a consolidated total net leverage ratio (as calculated in accordance with the terms of the Credit Agreement) of not greater than (i) 5.00 to 1.00 for the first four fiscal quarters after the Finisar Closing Date, commencing with the first full fiscal quarter after the Finisar Closing Date, (ii) 4.50 to 1.00 for the fifth fiscal quarter through and including the eighth fiscal quarter after the Finisar Closing Date, and (iii) 4.00 to 1.00 for each subsequent fiscal quarter. As of June 30, 2021, the Company was in compliance with all financial covenants under the Credit Agreement.

0.50% Finisar Convertible Notes

Finisar’s outstanding 0.50% Convertible Senior Notes due 2036 (the “Finisar Notes”) may be redeemed at any time on or after December 22, 2021 in whole or in part at the option of the Company at a redemption price equal to one hundred percent (100%) of the principal amount of such Finisar Notes plus accrued and unpaid interest. Each holder of Finisar Notes also may require Finisar to repurchase all or any portion of such holder’s outstanding Finisar Notes for cash on December 15, 2021, December 15, 2026 and December 15, 2031 at a repurchase price equal to one hundred percent ( 100%of the principal amount of such Finisar Notes plus accrued and unpaid interest. The Finisar Notes will mature on December 15, 2036. Interest on the Finisar Notes accrues at 0.50% per annum, paid semi-annually, in arrears, on June 15 and December 15 of each year.

In connection with the acquisition of Finisar, the Company, Finisar and the trustee entered into a First Supplemental Indenture, dated as of September 24, 2019 (the “First Supplemental Indenture”). The First Supplemental Indenture supplements the base indenture (as supplemented, the “Finisar Indenture”), which governs the Finisar Notes. Pursuant to the terms of the First Supplemental Indenture, the Company has fully and unconditionally guaranteed, on a senior unsecured basis, the due and punctual payment and performance of all obligations of Finisar to the holders of the Finisar Notes. The First Supplemental Indenture also provides that the right of holders of Finisar Notes to convert Finisar Notes into cash and/or shares of Finisar’s

61

common stock, is changed to a right to convert Finisar Notes into cash and shares of the Company’s common stock, subject to the terms of the Finisar Indenture.

0.25% Convertible Senior Notes

In August 2017, the Company issued and sold $345 million aggregate principal amount of the II-VI Notes in a private placement to qualified institutional buyers within the meaning of Rule 144A under the Securities Act of 1933, as amended.

As a result of our cash conversion option, the Company separately accounted for the value of the embedded conversion option as a debt discount, which was $58 million as of June 30, 2021. The value of the embedded conversion option was determined based on the estimated fair value of the debt without the conversion feature, which was determined using an expected present value technique (income approach) to estimate the fair value of similar nonconvertible debt; the debt discount is being amortized as additional non-cash interest expense over the term of the II-VI Notes using the effective interest method.

The equity component is not remeasured as long as it continues to meet the conditions for equity classification. The initial conversion rate is 21.25 shares of common stock per $1,000 principal amount of II-VI Notes, which is equivalent to an initial conversion price of $47.06 per share of II-VI common stock. Throughout the term of the II-VI Notes, the conversion rate may be adjusted upon the occurrence of certain events. The if-converted value of the II-VI Notes amounted to $532 million as of June 30, 2021 and $346 million as of June 30, 2020 (based on the Company’s closing stock price on the last trading day of the fiscal periods then ended).

Prior to the close of business on the business day immediately preceding June 1, 2022, the Notes will be convertible only under the following circumstances:

(i) during any fiscal quarter commencing after the fiscal quarter ending on December 31, 2017 (and only during such fiscal quarter), if the last reported sale price of the II-VI Common Stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

(ii) during the five business day period immediately after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the II-VI Common Stock and the conversion rate on each such trading day; or

(iii) upon the occurrence of certain specified corporate events.

On or after June 1, 2022 until the close of business on the business day immediately preceding the maturity date, holders may convert their Notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of II-VI Common Stock or a combination of cash and shares of II-VI Common Stock, at the Company’s election.

Because the last reported sale price of II-VI Common Stock for at least 20 trading days during the period of 30 consecutive trading days ending on the last trading day of the calendar quarter ended June 30, 2021 was equal to or greater than 130% of the applicable conversion price on each applicable trading day, the II-VI Notes are convertible at the option of the holders thereof during the fiscal quarter ending September 30, 2021.

Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of II-VI Common Stock or a combination of cash and shares of II-VI Common Stock, at the Company’s election.

Holders of the II-VI Notes will not receive any cash payment representing accrued and unpaid interest upon conversion of a II-VI Note. Accrued but unpaid interest will be deemed to be paid in full upon conversion rather than cancelled, extinguished or forfeited. II-VI Notes were convertible during the quarters ended March 31, and June 30, 2021; conversions were immaterial.

62

The following table sets forth total interest expense recognized related to the II-VI Notes for the years ended June 30, 2021, 2020 and 2019 ($000):

	Year Ended June 30, 2021		Year Ended June 30, 2020		Year Ended June 30, 2019
0.25% contractual coupon	$	874	$	876	$	874
Amortization of debt discount and debt issuance costs including initial purchaser discount	13,748		13,172		12,550
Interest expense	$	14,622	$	14,048	$	13,424

The effective interest rate on the liability component for the periods presented was 5%. The unamortized discount amounted to $15 million as of June 30, 2021, and is being amortized over the remaining life of the notes

Aggregate Availability

The Company had aggregate availability of $449 million under its Revolving Credit Facility as of June 30, 2021.

Weighted Average Interest Rate

The weighted average interest rate of total borrowings was 1% and 3% for the years ended June 30, 2021 and 2020, respectively.

Share Repurchase Programs

In August 2017, in conjunction with the Company’s offering and sale of the II-VI Notes, the Company was authorized to purchase up to $50 million of its common stock with a portion of the net proceeds received from the offering and sale of those convertible notes. The shares that were purchased by the Company pursuant to this authorization were retained as treasury stock and are available for general corporate purposes. The Company purchased 1,414,900 shares of its common stock for approximately $50 million pursuant to this authorization.

In August 2014, the Company’s Board of Directors authorized the Company to purchase up to $50 million of its common stock through a share repurchase program (the “Program”) that calls for shares to be purchased in the open market or in private transactions from time to time. The Program has no expiration and may be suspended or discontinued at any time. Shares purchased by the Company are retained as treasury stock and available for general corporate purposes. The Company did not repurchase shares pursuant to this Program during the fiscal year ended June 30, 2021. During the fiscal year ended June 30, 2020, the Company purchased 50,000 shares of its common stock for $2 million under this program. As of June 30, 2021, the Company has cumulatively purchased 1,416,587 shares of its common stock pursuant to the Program for approximately $22 million. The dollar value of shares as of June 30, 2021 that may yet be purchased under the Program is approximately $28 million.

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

	June 30, 2021		June 30, 2020
Cash and cash equivalents	$	1,592	$	493
Available borrowing capacity	449		375
Total debt obligations	1,375		2,255

The Company believes cash flow from operations, existing cash reserves and available borrowing capacity from its credit facilities and its recent equity raise will be sufficient to fund its needs for working capital, capital expenditures, repayment of scheduled long-term borrowings and lease obligations, investments in internal research and development, share repurchases, and internal and external growth objectives at least through fiscal year 2022.

63

The Company’s 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, 2021, the Company held approximately $406 million of cash and cash equivalents outside of the United States. Cash balances held outside the United States could be repatriated to the United States.

Off-Balance Sheet Arrangements

The Company’s off-balance sheet arrangements include the purchase obligations disclosed in the contractual obligations table below. The Company enters into these off-balance sheet arrangements to acquire goods and services used in its business.

Total	$	2,080,312	$	466,714	$	595,744	$	926,189	$	91,665

(1)Interest payments represent both variable and fixed rate interest obligations based on the interest rates in effect at June 30, 2021 relating to the Senior Credit Facilities, the currently outstanding 0.50% convertible senior notes assumed in the Finisar Acquisition, and the currently outstanding 0.25% Convertible Senior Notes due 2022.  These interest payments do not reflect the impact of the interest rate swap that hedges our variable interest payments to fixed interest payments.

(2)A purchase obligation is defined as an agreement to purchase goods or services that is enforceable and legally binding on the Company and that specifies all significant terms, including fixed or minimum quantities to be purchased, minimum or variable price provisions, and the approximate timing of the transaction. These amounts are primarily composed of open purchase order commitments to vendors for the purchase of supplies and materials.

Pension obligations are not included in the table above. Estimated funding obligations are determined by asset performance, workforce and retiree demographics, tax and employment laws and other actuarial assumptions which may change the annual funding obligations. The funded status of our defined benefit plans is disclosed in Note 17 to the Company’s Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

The Company’s gross unrecognized income tax benefit at June 30, 2021 has been excluded from the table above because the Company is not currently able to reasonably estimate the amount by which the liability will increase or decrease over time.

Item 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

MARKET RISKS

The Company is exposed to market risks arising from adverse changes in foreign currency exchange rates and interest rates. In the normal course of business, the Company uses a variety of techniques and derivative financial instruments as part of its overall risk management strategy, which is primarily focused on its exposure in relation to the Chinese Renminbi, Swiss Franc, Malaysian Ringgit and the Japanese Yen. No significant changes have occurred in the techniques and instruments used.

Interest Rate Risk

As of June 30, 2021, the Company’s total borrowings include variable rate borrowings, which exposes the Company to changes in interest rates. In November 2019, the Company entered into an interest rate swap contract to limit the exposure of its variable interest rate debt by effectively converting a portion of interest payments to fixed interest rate debt. However in March of 2020, the Federal Reserve lowered the interest rates, putting our hedge in a negative position. With the hedge in place, a change in the interest rate of 100 basis points on these variable rate borrowings would have resulted in additional interest expense of $12 million for the year ended June 30, 2021.

Item 8.        FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

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. 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, 2021. 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. Management excluded from the scope of its assessment of internal control over financial reporting the internal controls of Ascatron, which was acquired in August 2020, and Innovion, which was acquired in October 2020. The recent acquisitions excluded from management’s assessment of internal controls over financial reporting represented approximately $141.4 million and $117.4 million of total assets and net assets, respectively, as of June 30, 2021 and approximately $22.4 million and $2.5 million of total revenues and net loss, respectively, for the fiscal year then ended. Based on the evaluation, management concluded that as of June 30, 2021, 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, 2021. Its report is included herein.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of II-VI Incorporated

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of II-VI Incorporated and Subsidiaries (the Company) as of June 30, 2021 and 2020, the related consolidated statements of earnings (loss), comprehensive income (loss), shareholders’ equity and cash flows for each of the three years in the period ended June 30, 2021, and the related notes and the 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, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended June 30, 2021, 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, 2021, 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 20, 2021 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 Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Accounting for Series A Mandatory Convertible Preferred Stock

Description of the Matter

As described in Note 11 to the consolidated financial statements, on July 7, 2020, the Company issued shares of Series A Mandatory Convertible Preferred Stock. Upon conversion, on the mandatory conversion date, each outstanding share of Series A Mandatory Convertible Preferred Stock, unless previously converted, will automatically convert into a number of shares of the Company’s common stock determined based on the market value of the Company’s common stock on the mandatory conversion date. Auditing the Company’s accounting for the Series A Mandatory Convertible Preferred Stock was complex due to the significant estimation uncertainty involved in estimating the future market value of the Company’s common stock on the mandatory conversion date, which was used to determine whether the Series A Mandatory Convertible Preferred Stock should be classified within shareholders’ equity on the consolidated balance sheet as well as the related impact to the Company’s earnings per share. The Company used a Monte Carlo simulation model to estimate the future market value of its common stock on the mandatory conversion date, which considers inputs such as volatility and cost of equity, which are forward-looking and could be affected by future economic and market conditions.

68

How We Addressed the Matter in Our Audit	We obtained an understanding, evaluated the design and tested the operating effectiveness of controls relating to management’s accounting for the Series A Mandatory Convertible Preferred Stock. For example, we tested controls that address the risks of material misstatement relating to the estimation of the future market value of the Company’s common stock on the mandatory conversion date, including management’s review of the estimation methodology and significant inputs. To test the Company’s accounting for the Series A Mandatory Convertible Preferred Stock, our audit procedures included, among others, reading the relevant agreements and the Company’s accounting analysis and evaluating the Company’s conclusions as compared to the relevant accounting guidance. To test the estimated future market value of the Company’s common stock, our audit procedures included, among others, assessing the appropriateness of the estimation methodology used and evaluating the significant inputs. We compared the forecasted volatility of the Company’s common stock price to its historical volatility and compared the cost of equity to prior valuations performed by the Company. We also performed sensitivity analyses to evaluate the changes in the estimated future market value of the Company’s common stock that would result from changes in the significant inputs. We involved our valuation specialist to assist in evaluating the methodology used, to test certain significant inputs and to perform comparative calculations.
Accounting for Series B Convertible Preferred Stock
Description of the Matter	As described in Notes 3, 11 and 16 to the consolidated financial statements, the Company entered into an investment agreement, dated March 25, 2021, and amended and restated as of March 30, 2021, pursuant to which: (1) on March 31, 2021, the Company issued shares of Series B-1 Convertible Preferred Stock; and (2) the Company agreed to issue, immediately prior to the closing of the Company’s acquisition of Coherent, Inc., additional shares of Series B-2 Convertible Preferred Stock. The Series B-1 and B-2 Convertible Preferred Stock are contingently redeemable at the option of the holder on or after the tenth anniversary of the issuance or upon a certain change in control. The Company has concluded that (1) the obligation to issue the shares of Series B-1 Convertible Preferred Stock was required to be measured at fair value as an asset or liability with changes in fair value recognized in earnings; and (2) the obligation to issue the shares of Series B-2 Convertible Preferred Stock is an embedded feature that does not require bifurcation for separate accounting. Auditing the Company’s accounting for the obligations to issue shares of Series B-1 and B-2 Convertible Preferred Stock was complex due to the significant judgments made by management in determining whether each obligation should be classified and measured as an asset or liability on the consolidated balance sheet or comprises an embedded feature requiring bifurcation and separate accounting.
How We Addressed the Matter in Our Audit	We obtained an understanding, evaluated the design and tested the operating effectiveness of controls relating to management’s accounting for the Series B Convertible Preferred Stock, including management’s review of the relevant agreements and evaluation of the accounting guidance. To test the Company’s accounting for the obligations to issue shares of Series B-1 and B-2 Convertible Preferred Stock, our audit procedures included, among others, reading the relevant agreements and the Company’s accounting analysis, assessing the pertinent provisions of the Series B-1 and B-2 Convertible Preferred Stock, and evaluating the Company’s conclusions as compared to the relevant accounting guidance.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of II-VI Incorporated

Opinion on Internal Control over Financial Reporting

We have audited II-VI Incorporated and Subsidiaries’ internal control over financial reporting as of June 30, 2021, 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, II-VI Incorporated and Subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of June 30, 2021, based on the COSO criteria.

As indicated in the accompanying Management’s Report on Internal Control Over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Ascatron AB (“Ascatron”) and INNOViON Corporation (“Innovion”), which are included in the June 30, 2021 consolidated financial statements of the Company and constituted $141.4 million and $117.4 million of total and net assets, respectively, as of June 30, 2021 and $22.4 million and $2.5 million of revenues and net loss, respectively, for the fiscal year then ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of Ascatron and Innovion.

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, 2021 and 2020, the related consolidated statements of earnings (loss), comprehensive income (loss), shareholders’ equity and cash flows for each of the three years in the period ended June 30, 2021, and the related notes and the financial statement schedule listed in the Index at Item 15(a)(2) and our report dated August 20, 2021 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.

II-VI Incorporated and Subsidiaries

Notes to the Consolidated Financial Statements

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

Nature of Business. II-VI Incorporated and its subsidiaries (the “Company,” “we,” “us,” or “our”), a global leader in engineered materials and optoelectronic components and devices, is a vertically-integrated manufacturing company that develops, manufactures and markets engineered materials and optoelectronic components and devices for precision use in industrial materials processing, optical communications, aerospace and defense, consumer electronics, semiconductor capital equipment, life sciences and automotive applications. 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 the Company’s manufacturing yields. The Company has not experienced significant production delays due to a shortage of materials. However, the Company does occasionally experience problems associated with vendor-supplied materials not meeting specifications for quality or purity. A significant failure of the Company’s suppliers to deliver sufficient quantities of necessary high-quality materials on a timely basis could have a material adverse effect on the Company’s results of operations.

In March 2020, the World Health Organization declared the outbreak of COVID-19 as a pandemic, which continues to spread throughout the United States and world. The Company is closely monitoring the impact of the COVID-19 pandemic on all aspects of our business including the impact to our suppliers and customers as well as the impact to the countries and markets in which II-VI operates. At the onset of the COVID-19 outbreak, the Company began focusing intensely on mitigating the adverse impacts of COVID-19 on foreign and domestic operations starting by protecting its employees, suppliers and customers.

Principles of Consolidation. The Consolidated Financial Statements include the accounts of the Company. All intercompany transactions and balances have been eliminated.

Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those 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 and Cash Equivalents. The Company considers highly liquid investment instruments with an original maturity of three months or less to be cash equivalents. We place our cash and cash equivalents with high credit quality financial institutions and to date have not experienced credit losses in these instruments.

Accounts Receivable. The Company makes estimates evaluating its allowance for doubtful accounts. The Company continuously monitors collections and payments from its customers and maintains a provision for estimated credit losses based upon its historical experience, current market conditions and any specific customer collection issues that it has identified.

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, if applicable, other factors, including known trends, market conditions, currency exchange rates and other such issues. The Company generally records 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. The Company reviews its

77

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 20 years and 3 to 20 years for machinery and equipment.

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 the Company's right to use an underlying asset for the lease term, and lease liabilities represent the Company's 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. The Company uses 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. The Company has 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 13 for additional information.

Business Combinations. The Company accounts for business acquisitions 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.

On August 20, 2020, the Company acquired all of the outstanding shares of Ascatron AB ("Ascatron"), located in Sweden and on October 1, 2020, the Company acquired the remaining 6.1% interest in INNOViON Corporation ("Innovion"). Refer to Note 4 Acquisitions for further information regarding the Innovion and Ascatron acquisitions.

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. The Company tests 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 the Company’s reporting units to the recorded value (including goodwill). The Company uses a discounted cash flow (“DCF”) model and/or a market analysis to determine the fair value of its 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.

The Company has the option to perform a qualitative assessment of goodwill prior to completing the quantitative assessment described above to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill and other intangible assets. If the Company concludes that this is the case, it must perform the quantitative assessment. Otherwise, the Company will forego the quantitative assessment and does not need to perform any further testing. As of April 1 of fiscal years 2021 and 2020, the Company completed its annual impairment tests of its reporting units using the quantitative assessment. Based on the results of these analyses the Company’s goodwill was not impaired.

Intangibles. Intangible assets are initially recorded at their cost or fair value upon acquisition. Finite-lived intangible assets are amortized for financial reporting purposes using the straight-line method over the estimated useful lives of the assets ranging from 3 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.

78

Investments in Other Entities. In the normal course of business, the Company enters into various types of investment arrangements, each having unique terms and conditions. These investments may include equity interests held by the Company in business entities, including general or limited partnerships, contractual ventures, or other forms of equity participation. The Company determines whether such investments involve a variable interest entity (“VIE”) based on the characteristics of the subject entity. If the entity is determined to be a VIE, then management determines if the Company is the primary beneficiary of the entity and whether or not consolidation of the VIE is required. The primary beneficiary consolidating the VIE must normally have both (i) the power to direct the activities of a VIE that most significantly affect the VIE’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE, in either case that could potentially be significant to the VIE. When the Company is deemed to be the primary beneficiary, the VIE is consolidated and the other party’s equity interest in the VIE is accounted for as a noncontrolling interest.

The Company generally accounts for investments it makes in VIEs in which it has determined that it does not have a controlling financial interest but has significant influence over or holds at least a 20% ownership interest using the equity method. Any such investment not meeting the parameters to be accounted under the equity method would be accounted for under ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. If an entity fails to meet the characteristics of a VIE, management then evaluates such entity under the voting model. Under the voting model, management consolidates the entity if they determine that the Company, directly or indirectly, has greater than 50% of the voting shares and determines that other equity holders do not have substantive participating rights.

Series A Mandatory Convertible Preferred Stock. The II-VI Series A Mandatory Convertible Preferred Stock is initially measured at fair value, less underwriting discounts and commissions and offering expenses paid by the Company. The Preferred Stock’s dividends are cumulative, at 6% per annum.

Series B Convertible Preferred Stock. The II-VI Series B-1 Convertible Preferred Stock is 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 Available to the Common Shareholder.

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. Legal costs incurred in connection with loss contingencies are expensed as incurred. Such accruals 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. The Company had no material loss contingency liabilities at June 30, 2021 related to commitments and contingencies.

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.

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.

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 the Company’s customer have been satisfied and control has transferred to the customer. The Company has elected the practical expedient to exclude all taxes from the measurement of the transaction price.

For contracts with commercial customers, which comprise the majority of the Company’s performance obligations, ownership of the goods and associated revenue are transferred to customers at a point in time, generally upon shipment of a product to the

79

customer or receipt of the product by 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.

Contracts with the U.S. government through its prime contractors are typically for products or services with no alternative future use to the Company with an enforceable right to payment for performance completed to date, whereas commercial contracts typically have alternative use. Customized products with no alternative future use to the Company with an enforceable right to payment for performance completed to date are recorded over time utilizing the output method of units delivered. The Company considers this to be a faithful depiction of the transfer to the customer of revenue over time due to short cycle time and immaterial work-in-process balances. The majority of contracts typically require payment within 30 to 90 days after transfer of ownership to the customer.

Service revenue includes repairs, non-recurring engineering, 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. Non-recurring engineering arrangements are typically recognized over time under 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. The majority of contracts typically require payment within 90 days.

The Company's revenue recognition policy is consistently applied across the Company's segments, product lines, services, and geographical locations. For the periods covered herein, the Company measures revenue based on the amount of consideration it 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. The Company determines 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, the Company expenses 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. The Company has elected to recognize the costs for freight and shipping when control over products has transferred to the customer as an expense in cost of goods sold.

The Company monitors and tracks the amount of product returns and reduces revenue at the time of shipment for the estimated amount of future returns, based on historical experience.

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

The Company believes 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 5. Revenue from Contracts with Customers.

Research and Development. Research and development 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 research and development expenses as incurred.

Share-Based Compensation. Share-based compensation arrangements require the recognition in net earnings (loss) of the grant date fair value of stock compensation (for equity-classified awards). The Company recognizes 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 the Company’s historical experience of pre-vesting cancellations. The Company 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.

Accumulated Other Comprehensive Income (Loss). Accumulated other comprehensive income (loss) 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. Accumulated other comprehensive income (loss) is a component of shareholders’ equity and consists of accumulated foreign currency translation adjustments, changes in the fair value of interest rate swap derivative instruments, and pension adjustments.

80

Fair Value Measurements. The Company applies 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, the Company considers the principal or most advantageous market in which the Company 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 Financial Accounting Standards

Financial Instruments - Credit Losses

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, Financial Instruments - Credit Losses (Topic 326), which modifies the measurement of expected credit losses on certain types of financial instruments, including trade receivables. The Company adopted this standard on July 1, 2020. The adoption did not have a material impact on the Company's consolidated financial statements.

Pronouncements Currently Under Evaluation

In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40) ("ASU 2020-06"). The update simplifies the accounting for convertible instruments by eliminating two accounting models (i.e., the cash conversion model and beneficial conversion feature model) and reducing the number of embedded conversion features that could be recognized separately from the host contract. ASU 2020-06 also enhances transparency and improves disclosures for convertible instruments and earnings per share guidance. ASC 2020-06 is effective for annual reporting periods beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. This update permits the use of either the modified retrospective or fully retrospective method of transition. We plan to adopt this ASU as of July 1, 2021. We estimate the impact of adopting ASU 2020-06 will result in an increase in net debt of $15 million, a decrease in the deferred tax liability of $3 million, a decrease in common stock of $56 million, and an increase in retained earnings of $45 million. The adoption will result in a decrease of interest expense of approximately $12 million in fiscal year 2022.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients to ease the potential burden of accounting for the effects of reference rate reform as it pertains to contract modifications of debt and lease contracts and derivative contracts identified in a hedging relationship. These amendments are effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Company is in the process of evaluating the impact of the pronouncement.

Note 3. Pending Coherent Acquisition

On March 25, 2021, II-VI, Coherent, Inc., and Watson Merger Sub Inc., a wholly owned subsidiary of II-VI (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”). Pursuant to the terms of the Merger Agreement, and subject to the conditions set forth therein, Merger Sub will be merged with and into Coherent, and Coherent will continue as the surviving corporation in the merger and wholly owned subsidiary of II-VI (the “Merger”).

Pursuant to the terms of the Merger Agreement, and subject to the conditions set forth therein, at the effective time of the Merger (the “Effective Time”), each share of common stock of Coherent, par value $0.01 per share (the “Coherent Common Stock”), issued and outstanding immediately prior to the Effective Time will be canceled and extinguished and automatically converted into the right to receive the following consideration (collectively, the “Merger Consideration”):

(A) $220.00 in cash, without interest (the “Cash Consideration”), and

(B) 0.91 of a validly issued, fully paid and nonassessable share of common stock of II-VI, no par value per share (“II-VI Common Stock”)

Pursuant to the terms of the Merger Agreement, each Coherent restricted stock unit award (a “Coherent RSU”), other than Director RSUs (as defined below), outstanding immediately prior to the Effective Time will be automatically converted into

81

time-based restricted stock units denominated in shares of II-VI Common Stock entitling the holder to receive, upon settlement, a number of shares of II-VI Common Stock equal to the number of shares of Coherent Common Stock subject to the Coherent RSU multiplied by the sum of (A) 0.91, and (B) the quotient obtained by dividing the Cash Consideration by the volume weighted average price of a share of II-VI Common Stock for a 10 trading day period ending prior to the closing of the Merger (the “Closing”). For Coherent RSUs subject to performance-based vesting conditions and metrics, the number of shares of II-VI Common Stock subject to the converted Coherent RSUs will be determined after giving effect to the Coherent Board of Directors’ determination of the number of Coherent RSUs earned, based on the greater of the target or actual level of achievement of such goals or metrics immediately prior to the Effective Time.

The converted Coherent RSUs generally will be subject to the same terms and conditions that applied to the awards immediately prior to the Effective Time, provided that any Coherent RSUs subject to performance-based vesting conditions will be subject solely to time- and service-based vesting. Each Coherent RSU that is outstanding as of the date of the Merger Agreement and as of immediately prior to the Effective Time will be entitled to the following vesting acceleration benefits:

(A) for any holder of Coherent RSUs who is a participant under Coherent’s Change of Control and Leadership Change Severance Plan (the “CIC Plan”), the acceleration benefits under the CIC Plan upon such participant’s involuntary termination of employment in accordance with the terms and conditions set forth therein; and

(B) for any holder who is not a participant in the CIC Plan, the following vesting acceleration benefits upon his or her termination of employment by Coherent, II-VI, or their respective subsidiaries without “cause” within the period beginning immediately following the date of the Closing and ending on the date that is 12 months following the date of the Closing (or, if earlier, December 31, 2022) (a “Qualifying Termination”), (1) if such holder’s Qualifying Termination occurs during calendar year 2021, the sum of: (x) 100% of the total number of converted Coherent RSUs that otherwise would have vested during calendar year 2021 under the applicable vesting schedule in effect on the Closing had such holder remained employed with Coherent, II-VI, or their respective subsidiaries through the last applicable vesting date for such award in calendar year 2021 (and reduced by the total number of converted Coherent RSUs that vested in calendar year 2021 prior to such Qualifying Termination) plus (y) 50% of the total number of converted Coherent RSUs that otherwise would have vested during calendar year 2022 under the applicable vesting schedule in effect on the Closing had such holder remained employed with Coherent, II-VI, or their respective subsidiaries through the last applicable vesting date for such award in calendar year 2022, or (2) if such holder’s Qualifying Termination occurs during calendar year 2022, 50% of the total number of converted Coherent RSUs that otherwise would have vested during calendar year 2022 under the applicable vesting schedule in effect on the Closing had such holder remained employed with Coherent, II-VI, or their respective subsidiaries through the last applicable vesting date for such award in calendar year 2022 (and reduced by the total number of converted Coherent RSUs that vested in calendar year 2022 prior to such Qualifying Termination).

Each Coherent RSU granted to a non-employee member of Coherent’s Board of Directors (“Director RSUs”) (whether or not vested) that is outstanding immediately prior to the Effective Time will automatically vest in full and be canceled and converted into the right to receive the Merger Consideration as if such Director RSU had been settled in shares of Coherent Common Stock immediately prior to the Effective Time.

The Boards of Directors of II-VI and Coherent unanimously approved the Merger and the Merger Agreement. II-VI filed with the SEC a registration statement on Form S-4 relating to the Merger, and the SEC declared that registration statement to be effective on May 6, 2021. Shareholders of II-VI and stockholders of Coherent voted to approve proposals related to the Merger at special meetings held on June 24, 2021 by the respective companies.

The completion of the Merger is subject to the satisfaction or waiver of certain additional customary closing conditions, including review and approval of the Merger by the State Administration for Market Regulation in China. Subject to the satisfaction or waiver of each of the closing conditions, II-VI expects that the Merger will be completed by year-end 2021 or at the beginning of the first calendar quarter of 2022. However, it is possible that factors outside the control of both companies could result in the Merger being completed at a different time or not at all.

In connection with entering into the Merger Agreement, II-VI has obtained a fully underwritten financing commitment pursuant to a commitment letter (the “Commitment Letter”), dated as of March 25, 2021, as further amended and restated on April 21, 2021, with JPMorgan Chase Bank, N.A., Citigroup Global Markets Inc., MUFG Bank, Ltd., MUFG Securities Americas Inc., PNC Capital Markets LLC, PNC Bank, National Association, HSBC Securities (USA) Inc., HSBC Bank USA, National Association, Citizens Bank, N.A., Mizuho Bank, Ltd., BMO Capital Markets Corp., Bank of Montreal, TD Securities (USA) LLC, The Toronto-Dominion Bank, New York Branch, TD Bank, N.A. and First National Bank of Pennsylvania (collectively, the “Commitment Parties”) pursuant to which the Commitment Parties have committed to provide up to $5.1 billion in debt

financing ( the “Debt Financing”). The obligation of the Commitment Parties to provide the Debt Financing provided for in the Commitment Letter is subject to a number of customary conditions.

In connection with entering into the Merger Agreement, II-VI entered into an Amended and Restated Investment Agreement, dated as of March 30, 2021, (the “Investment Agreement”), with BCPE Watson (DE) SPV, LP, an affiliate of Bain Capital Private Equity, LP (the “Investor”). Pursuant to the terms of the Investment Agreement, on March 31, 2021, II-VI issued, sold, and delivered to the Investor 75,000 shares of a new Series B-1 Convertible Preferred Stock of the Company, no par value per share (“II-VI Series B-1 Convertible Preferred Stock”), for $10,000 per share (the “Equity Per Share Price”), resulting in an aggregate purchase price of $750 million. Subject to the terms and conditions of the Investment Agreement, among other things, the Company and the Investor also agreed that the Company would issue, sell and deliver to the Investor:

•105,000 shares of a new Series B-2 Convertible Preferred Stock of the Company, no par value per share (“II-VI Series B-2 Convertible Preferred Stock,” and together with the II-VI Series B-1 Convertible Preferred Stock, “New II-VI Convertible Preferred Stock”), for a purchase price per share equal to the Equity Per Share Price, resulting in an aggregate purchase price of $1.1 billion, immediately prior to Closing; and

•immediately prior to Closing, if elected by the Company and agreed by the Investor, up to an additional 35,000 shares of II-VI Series B-2 Convertible Preferred Stock (the "Upsize Shares") for a purchase price per share equal to the Equity Per Share Price, resulting in an aggregate maximum purchase price for the Upsize Shares of $350 million.

Following the Company’s provision of notice to the Investor of its election to offer the Upsize Shares, the Investor informed the Company on June 8, 2021 of its agreement to purchase the Upsize Shares from the Company immediately prior to the Closing, increasing the Investor’s total equity commitment to II-VI pursuant to the Investment Agreement to $2.2 billion.

The expenses associated with the pending acquisition for the year ended June 30, 2021, have not been allocated to an Operating Segment, and are presented in the Unallocated and Other in Note 15, Segment and Geographic Reporting.

Note 4.        Acquisitions

Acquisition of Ascatron AB

On August 20, 2020, the Company acquired all of the outstanding shares of Ascatron, located in Sweden. The acquisition will add essential elements to the Company's vertically integrated silicon carbide technology platform. Purchase price consideration totaled $37 million.

The Company utilized the widely accepted income-based approach (relief-from-royalty method) to perform the preliminary purchase price allocation.

The following table presents the final allocation of the purchase price of the assets acquired and liabilities assumed at the date of acquisitions ($000):

	Previously Reported September 30, 2020		Measurement Period Adjustments (a)		As Adjusted
Assets
Developed technology	$	20,000	$	(3,622)	$	16,378
Goodwill	18,922		3,018		21,940

Net assets acquired	$	36,704	$	—	$	36,704

83

(a) The Company recorded measurement period adjustments to its preliminary acquisition date fair values due to the refinement of its valuation models, assumptions and inputs. The measurement period adjustments were based upon information obtained about facts and circumstances that existed at the acquisition date that, if known, would have affected the measurement of the amounts recognized at that date.

The goodwill is recorded in the Compound Semiconductors segment and is attributed to the workforce acquired as part of the transaction. The goodwill is non-deductible for income tax purposes. Transaction expenses related to the acquisition totaled $2 million for the year ended June 30, 2021 and are included in Selling, General and Administrative expenses in the Consolidated Statements of Earnings (Loss). Technology is being amortized with a useful life of approximately 17 years.

The revenues and net loss from Ascatron included in the Company's Consolidated Statement of Earnings (Loss) for the year ended June 30, 2021 were $1 million and $3 million, respectively.

Certain data necessary to complete the purchase price allocation remains preliminary, including, but not limited to, finalization

of certain income tax computations and other assumed liabilities. The Company expects to complete the purchase price allocation within 12 months from the Closing Date, at which time the purchase price allocation set forth herein may be revised.

Purchase of Equity Investment in INNOViON Corporation

On October 1, 2020, II-VI acquired the remaining 6.1% interest in Innovion for $4 million. Innovion is a provider of ion implantation services supporting unique capabilities in semiconductor materials processing. This acquisition will add essential elements to the Company's vertically integrated silicon carbide technology platform.

Through the period ended December 31, 2020, the Company held a 93.9% investment in Innovion which was accounted for as an equity method investment. The Company accounted for the acquisition of the remaining equity of Innovion as a step acquisition, which required remeasurement of the Company's previous ownership interest to fair value prior to completing purchase accounting. Using step acquisition accounting the Company increased the value of its previously held equity investment to its fair value of $67 million, which resulted in a gain of approximately $7 million, recorded in other expense (income), net in the Consolidated Statements of Earnings (Loss) in the second quarter of fiscal year 2021.

The Company utilized widely accepted income-based, market-based, and cost-based valuation approaches to perform the preliminary purchase price allocation and determine the fair value of the previously held equity method investment. Income-based valuation approaches included the use of the multi-period excess earnings and relief-from-royalty methods for certain acquired intangible assets.

The following table presents the final allocation of the purchase price of the assets acquired and liabilities assumed at the date of acquisition ($000):

Senior Credit Facilities

The Company currently has Senior Credit Facilities with Bank of America, N.A., as Administrative Agent, Swing Line Lender and an L/C Issuer, and the other lenders party thereto.

The credit agreement governing the Senior Credit Facilities (the "Credit Agreement") provides for senior secured financing of $2.4 billion in the aggregate, consisting of

(i)Aggregate principal amount of $1,255 million for a five-year senior secured first-lien term A loan facility (the “Term A Facility”),

(ii)Aggregate principal amount of $720 million for a seven-year senior secured term B loan facility (the “Term B Facility” and together with the Term A Facility, the “Term Loan Facilities”), which was repaid in full during the quarter ended September 30, 2020, and

(iii)Aggregate principal amount of $450 million for a five-year senior secured first-lien revolving credit facility (the “Revolving Credit Facility” and together with the Term Loan Facilities, the “Senior Credit Facilities”).

The Credit Agreement also provides for a letter of credit sub-facility not to exceed $25 million and a swing loan sub-facility initially not to exceed $20 million.

89

The Term B Facility was repaid in full by the Company subsequent to the public offerings that closed on July 7, 2020. In conjunction with the repayment, the Company paid $1 million in associated interest and expensed $25 million of debt issuance costs related to the Term B Facility.

The Company is obligated to repay the outstanding principal amount of the Term A Facility in quarterly installments equal to 1.25% of the initial aggregate principal amount of the Term A Facility, with the remaining outstanding balance due and payable on the fifth anniversary of September 24, 2019 (the "Finisar Closing Date").

The Company’s obligations under the Senior Credit Facilities are guaranteed by each of the Company’s existing or future direct and indirect domestic subsidiaries (collectively, the “Guarantors”). Borrowings under the Senior Credit Facilities are collateralized by a first priority lien in substantially all of the assets of the Company and the Guarantors, except that no real property is collateral under the Senior Credit Facilities.

All amounts outstanding under the Senior Credit Facilities become due and payable 120 days prior to the maturity of the Company’s currently outstanding 0.25% Convertible Senior Notes due 2022 (the “II-VI Notes”) if (i) the II-VI Notes remain outstanding, and (ii) the Company has insufficient cash and borrowing availability to repay the principal amount of the II-VI Notes.

Amounts outstanding under the Senior Credit Facilities bear interest at a rate per annum equal to an applicable margin over a eurocurrency rate or an applicable margin over a base rate determined by reference to the highest of (a) the federal funds rate plus 0.50%, (b) Bank of America, N.A.’s prime rate and (c) a eurocurrency rate plus 1.00%, in each case as calculated in accordance with the terms of the Credit Agreement. The applicable interest rate would increase under certain circumstances relating to events of default.  The Company has entered into an interest rate swap contract to hedge its exposure to interest rate risk on its variable rate borrowings under the Senior Credit Facilities.  Refer to Note 15 for further information regarding this interest rate swap.

The Credit Agreement contains customary affirmative and negative covenants with respect to the Senior Credit Facilities, including limitations with respect to liens, investments, indebtedness, dividends, mergers and acquisitions, dispositions of assets and transactions with affiliates. The Company will be obligated to maintain a consolidated interest coverage ratio (as calculated in accordance with the terms of the Credit Agreement) as of the end of each fiscal quarter of not less than 3.00 to 1.00. The Company will be obligated to maintain a consolidated total net leverage ratio (as calculated in accordance with the terms of the Credit Agreement) of not greater than (i) 5.00 to 1.00 for the first four fiscal quarters after the Finisar Closing Date, commencing with the first full fiscal quarter after the Finisar Closing Date, (ii) 4.50 to 1.00 for the fifth fiscal quarter through and including the eighth fiscal quarter after the Finisar Closing Date, and (iii) 4.00 to 1.00 for each subsequent fiscal quarter. As of June 30, 2021, the Company was in compliance with all financial covenants under the Credit Agreement.

0.50% Finisar Convertible Notes

Finisar’s outstanding 0.50% Convertible Senior Notes due 2036 (the “Finisar Notes”) may be redeemed at any time on or after December 22, 2021 in whole or in part at the option of the Company at a redemption price equal to one hundred percent (100%) of the principal amount of such Finisar Notes plus accrued and unpaid interest. Each holder of Finisar Notes also may require Finisar to repurchase all or any portion of such holder’s outstanding Finisar Notes for cash on December 15, 2021, December 15, 2026 and December 15, 2031 at a repurchase price equal to one hundred percent ( 100%) of the principal amount of such Finisar Notes plus accrued and unpaid interest. The Finisar Notes will mature on December 15, 2036. Interest on the Finisar Notes accrues at 0.50% per annum, paid semi-annually, in arrears, on June 15 and December 15 of each year.

In connection with the acquisition of Finisar, the Company, Finisar and the trustee entered into a First Supplemental Indenture, dated as of September 24, 2019 (the “First Supplemental Indenture”). The First Supplemental Indenture supplements the base indenture (as supplemented, the “Finisar Indenture”), which governs the Finisar Notes. Pursuant to the terms of the First Supplemental Indenture, the Company has fully and unconditionally guaranteed, on a senior unsecured basis, the due and punctual payment and performance of all obligations of Finisar to the holders of the Finisar Notes. The First Supplemental Indenture also provides that the right of holders of Finisar Notes to convert Finisar Notes into cash and/or shares of Finisar’s common stock, is changed to a right to convert Finisar Notes into cash and shares of the Company’s common stock, subject to the terms of the Finisar Indenture.

0.25% Convertible Senior Notes

In August 2017, the Company issued and sold $345 million aggregate principal amount of the II-VI Notes in a private placement to qualified institutional buyers within the meaning of Rule 144A under the Securities Act of 1933, as amended.

90

As a result of our cash conversion option, the Company separately accounted for the value of the embedded conversion option as a debt discount, which was $58 million as of June 30, 2021. The value of the embedded conversion option was determined based on the estimated fair value of the debt without the conversion feature, which was determined using an expected present value technique (income approach) to estimate the fair value of similar nonconvertible debt; the debt discount is being amortized as additional non-cash interest expense over the term of the II-VI Notes using the effective interest method.

The equity component is not remeasured as long as it continues to meet the conditions for equity classification. The initial conversion rate is 21.25 shares of common stock per $1,000 principal amount of II-VI Notes, which is equivalent to an initial conversion price of $47.06 per share of II-VI common stock. Throughout the term of the II-VI Notes, the conversion rate may be adjusted upon the occurrence of certain events. The if-converted value of the II-VI Notes amounted to $532 million as of June 30, 2021 and $346 million as of June 30, 2020 (based on the Company’s closing stock price on the last trading day of the fiscal periods then ended).

Prior to the close of business on the business day immediately preceding June 1, 2022, the Notes will be convertible only under the following circumstances:

(i) during any fiscal quarter commencing after the fiscal quarter ending on December 31, 2017 (and only during such fiscal quarter), if the last reported sale price of the II-VI Common Stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

(ii) during the five business day period immediately after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the II-VI Common Stock and the conversion rate on each such trading day; or

(iii) upon the occurrence of certain specified corporate events.

On or after June 1, 2022 until the close of business on the business day immediately preceding the maturity date, holders may convert their Notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of II-VI Common Stock or a combination of cash and shares of II-VI Common Stock, at the Company’s election.

Because the last reported sale price of II-VI Common Stock for at least 20 trading days during the period of 30 consecutive trading days ending on the last trading day of the calendar quarter ended June 30, 2021 was equal to or greater than 130% of the applicable conversion price on each applicable trading day, the II-VI Notes are convertible at the option of the holders thereof during the fiscal quarter ending September 30, 2021.

Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of II-VI Common Stock or a combination of cash and shares of II-VI Common Stock, at the Company’s election.

Holders of the II-VI Notes will not receive any cash payment representing accrued and unpaid interest upon conversion of a II-VI Note. Accrued but unpaid interest will be deemed to be paid in full upon conversion rather than cancelled, extinguished or forfeited. II-VI Notes were convertible during the quarters ended March 31, and June 30, 2021; conversions were immaterial.

The following table sets forth total interest expense recognized related to the II-VI Notes for the years ended June 30, 2021, 2020 and 2019 ($000):

	Year Ended June 30, 2021		Year Ended June 30, 2020		Year Ended June 30, 2019

Interest expense	$	14,622	$	14,048	$	13,424

The effective interest rate on the liability component for the periods presented was 5%. The unamortized discount amounted to $15 million as of June 30, 2021, and is being amortized over the remaining life of the notes.

On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was signed into law. The Tax Act includes changes to the U.S. statutory federal tax rate and puts into effect the migration from a worldwide system of taxation to a territorial system, among other things. The Tax Act includes certain changes such as introducing a new category of income, referred to as global intangible low tax income (“GILTI”), related to earnings taxed at a low rate of foreign entities without a significant fixed asset base, and imposes additional limitations on the deductibility of interest and officer compensation. The Company made a final accounting policy election to treat taxes due from future inclusions in U.S. taxable income related to GILTI as a current period expense when incurred.

93

The Company previously considered the earnings in non-U.S. subsidiaries to be indefinitely reinvested and, accordingly, recorded no deferred income taxes.  As a result of the Act, among other things, the Company determined it 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 $22 million.

During the fiscal years ended June 30, 2021, 2020, and 2019, net cash paid by the Company for income taxes was $60 million, $40 million, and $26 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 3.22%, (8.91)% and 0.25% for the fiscal years ended June 30, 2021, 2020 and 2019, respectively, and the impact of the tax holidays on diluted earnings per share is $0.10, $0.07, and $0.00 for the fiscal years ended June 30, 2021, 2020, and 2019, respectively. The holiday related to II-VI Malaysia Advanced Manufacturing Center Sdn. Bhd will end during the fiscal year ended June 30, 2026, the holiday related to certain II-VI Laser Enterprise Philippines, Inc.'s business lines will end during the fiscal year ended June 30, 2022, and the holiday related to II-VI Vietnam Co., Ltd will end during the fiscal year ended June 30, 2024.

The Company has the following gross operating loss carryforwards and tax credit carryforwards as of June 30, 2021:

Type	Amount		Expiration Date
($000)
Tax credit carryforwards:
Federal research and development credits	$	79,211	June 2022-June 2041
Foreign tax credits	20,493		June 2022-June 2031
State tax credits	15,434		June 2022-June 2036
State tax credits (indefinite)	39,125		Indefinite
Operating loss carryforwards:
Loss carryforwards - federal	$	47,755	June 2022-June 2036

Loss carryforwards - foreign	17,375		June 2021-June 2040
Loss carryforwards - foreign (indefinite)	48,884		Indefinite

The Company has recorded a valuation allowance against the majority of the foreign and state loss and credit carryforwards. The Company’s U.S. federal loss carryforwards, federal research and development credit carryforwards, 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, 2021, 2020 and 2019 were as follows:

	2021		2020		2019
($000)
Beginning balance	$	42,803	$	11,520	$	9,892
Increases in current year tax positions	3,940		1,506		191

Ending balance	$	38,025	$	42,803	$	11,520

The Company classifies all estimated and actual interest and penalties as income tax expense. During fiscal years 2021, 2020 and 2019, there was $0.3 million, $0.6 million and $(0.1) million of interest and penalties within income tax expense, respectively. The Company had $3 million, $4 million and $1 million of interest and penalties accrued at June 30, 2021, 2020 and 2019, 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. 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 $26 million, $24 million and $6 million at June 30, 2021, 2020 and 2019, respectively. The Company expects a decrease of $2 million of unrecognized tax benefits during the next 12 months due to the expiration of statutes of limitation.

Fiscal years 2018 to 2021 remain open to examination by the Internal Revenue Service, fiscal years 2016 to 2021 remain open to examination by certain state jurisdictions, and fiscal years 2010 to 2021 remain open to examination by certain foreign taxing jurisdictions. The Company is currently under examination in New York for the years ended June 30, 2018 though June 30, 2019 and under examination for certain subsidiary companies in India for the year ended March 31, 2016; Philippines for the year ended June 30, 2019; and Germany for the years ended June 30, 2012 through June 30, 2018. The Company believes its income tax reserves for these tax matters are adequate.

Note 11. Equity and Redeemable Preferred Stock

Mandatory Convertible Preferred Stock

On July 2, 2020, II-VI announced the pricing of an underwritten public offering of 2,000,000 shares of 6.00% Series A Mandatory Convertible Preferred, no par value per share (“Mandatory Convertible Preferred Stock”), resulting in gross proceeds to II-VI from the offering of $400 million, before deducting the underwriting discounts and commissions and offering expenses payable by the Company (the “Preferred Stock Offering”). In addition, the underwriters had a 30-day option to purchase up to an additional 300,000 shares of Series A Mandatory Convertible Preferred Stock at the applicable public offering price, less underwriting discounts and commissions and solely to cover over-allotments with respect to the preferred stock offering. On July 2, 2020, the underwriters exercised the option in full, raising an additional approximately $60 million in gross proceeds. On July 7, 2020, the Company closed the Preferred Stock Offering, including the issuance and sale of 2 million shares of Mandatory Convertible Preferred Stock.

Upon conversion on the mandatory conversion date, July 1, 2023, as determined in accordance with the terms of the Mandatory Convertible Preferred Stock, each outstanding share of the Mandatory Convertible Preferred Stock, unless previously converted, will automatically convert into a number of shares of II-VI Common Stock equal to not more than 4.6512 shares of II-VI Common Stock and not less than 3.8760 shares of II-VI Common Stock (the “Minimum Conversion Rate”), depending on the applicable market value of the II-VI Common Stock, determined in accordance with the terms of the Mandatory Convertible Preferred Stock and subject to certain anti-dilution adjustments.

Other than in the event of one of certain fundamental changes, a holder of Mandatory Convertible Preferred Stock may, at any time prior to July 1, 2023, elect to convert such holder’s shares of Mandatory Convertible Preferred Stock, in whole or in part (but in no event less than one share of Mandatory Convertible Preferred Stock), at the Minimum Conversion Rate per share of Mandatory Convertible Preferred Stock, subject to certain anti-dilution adjustments.

If one of certain fundamental changes occurs on or prior to July 1, 2023, holders of the Mandatory Convertible Preferred Stock will have the right to convert their shares of Mandatory Convertible Preferred Stock, in whole or in part (but in no event less than one share of the Mandatory Convertible Preferred Stock), into shares of II-VI Common Stock at the conversion rate determined in accordance with the terms of the Mandatory Convertible Preferred Stock during the period beginning on, and including, the effective date of such change and ending on, and including, the date that is 20 calendar days after the effective date of such fundamental change (or, if later, the date that is 20 calendar days after holders receive notice of such fundamental change, but in no event later than July 1, 2023). Holders who convert their shares of the Mandatory Convertible Preferred Stock during that period will also receive a dividend make-whole amount and, to the extent there is any, the accumulated dividend amount, in each case as calculated in accordance with the terms of the Mandatory Convertible Preferred Stock.

Upon issuance of the Mandatory Convertible Preferred Stock, the Company used a Monte Carlo simulation model to estimate the future market value of the II-VI Common Stock on the mandatory conversion date, based on the following inputs:

95

Expected Volatility	50% - 55%
Cost of Equity	14% - 17%
Dividend Yield	none

Expected volatility is based on the historical volatility of II-VI Common Stock, taking into consideration the mean-reverting tendency of volatility and the expected term of the Mandatory Convertible Preferred Stock, as well as traded option contracts for II-VI Common Stock. The cost of equity was calculated over a three-year term, assuming a risk-free interest rate of 0.2% derived from the average U.S. Treasury Note rate during the period. The dividend yield of zero is based on the fact that the Company has never paid cash dividends on II-VI Common Stock and has no current intention to pay cash dividends on II-VI Common Stock in the future.

The Company declared $27 million of preferred stock dividends during fiscal year 2021 associated with the Mandatory Convertible Preferred Stock. Dividends from the quarter ended June 30, 2021 were $7 million and were presented as other accrued liabilities on the Consolidated Balance Sheet.

The following table presents dividends per share and dividends recognized for the year ended June 30, 2021:

	Year Ended June 30, 2021
Dividends per share	11.80
Series A Mandatory Convertible Preferred Stock dividends ($000)	27,140

Redeemable Convertible Preferred Stock

The Company issued 75,000 shares of II-VI Series B-1 Convertible Preferred Stock in the year ended June 30, 2021. Refer to Note 3. Pending Coherent Acquisition for additional information.

In connection with the execution of the Investment Agreement, on March 30, 2021, the Company filed a Statement with Respect to Shares (the “Statement”) with the Pennsylvania Department of State Corporation Bureau to establish the designation, rights and preferences of the II-VI Series B-1 Convertible Preferred Stock. The Statement became effective on March 30, 2021.

The shares of II-VI Series B-1 Convertible Preferred Stock accrue dividends at 5.00% per annum, subject to increase if II-VI defaults on payment obligations with respect to the New II-VI Convertible Preferred Stock, not to exceed 14% per annum. Until the fourth anniversary of March 31, 2021 (the “Initial Issue Date”), dividends are payable solely in-kind. After the fourth anniversary of the Initial Issue Date, dividends are payable on the applicable series, at the Company’s option, in cash, in-kind, or as a combination of both.

The shares of II-VI Series B-1 Convertible Preferred Stock are convertible into shares of II-VI Common Stock as follows:

•at any time after their issuance, at the election of the holder, each share of II-VI Series B-1 Convertible Preferred Stock may be converted into shares of II-VI Common Stock at a conversion price of $85.00 per share (“Conversion Price”), except that the shares of II-VI Series B-1 Convertible Preferred Stock will be so convertible only after the earliest to occur of (i) the issuance of shares of II-VI Series B-2 Convertible Preferred Stock upon the Closing, (ii) the termination of the Merger Agreement or (iii) the delivery by II-VI to the Investor of an offer to repurchase the II-VI Series B-1 Convertible Preferred Stock upon the occurrence of a Fundamental Change (as defined in the Statement); and

•at any time following the third anniversary of Initial Issue Date, at the election of II-VI, each share of II-VI Series B-1 Convertible Preferred Stock may be converted into shares of II-VI Common Stock at the then-applicable Conversion Price if the volume-weighted average price of II-VI Common Stock exceeds 150% of the then- applicable Conversion Price for 20 trading days out of any 30 consecutive trading days.

The II-VI Series B-1 Convertible Preferred Stock have voting rights, voting as one class with the II-VI Common Stock, on an as-converted basis, subject to limited exceptions.

96

On or at any time after the tenth anniversary of the Initial Issue Date:

•each holder has the right to require the Company to redeem all of their II-VI Series B-1 Convertible Preferred Stock, for cash, at a redemption price per share equal to the sum of the Stated Value for such shares (as defined in the Statement) 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 II-VI Series B-1 Convertible Preferred Stock outstanding, for cash, at the Redemption Price.

In connection with any Fundamental Change, and subject to the procedures set forth in the Statement, the Company must, or will cause the survivor of a Fundamental Change (such survivor of a Fundamental Change, the “Acquirer”) to, make an offer to repurchase, at the option and election of the holder thereof, each share of II-VI Series B-1 Convertible Preferred Stock then-outstanding (the “Fundamental Change Repurchase Offer”) 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 the fifth anniversary of the Initial Issue Date, the aggregate amount of all dividends that would have been paid (subject to certain exceptions), from the date of repurchase through the fifth anniversary of the Initial Issue Date.

The II-VI Series B-1 Convertible Preferred Stock is redeemable for cash outside of the control of the Company upon the exercise of the Put Rights, and upon a Fundamental Change, and is therefore classified as mezzanine equity.

The Company recognized $10 million of preferred stock dividends during the fiscal year ended 2021, which were presented as a reduction to retained earnings on the Consolidated Balance Sheet as of June 30, 2021. The Company incurred $27 million of transaction costs associated with the II-VI Series B-1 Convertible Preferred Stock, of which, $23 million were capitalized, and $4 million were expensed in the Selling, General, and Administrative expenses in the Consolidated Statements of Earnings (Loss) for the fiscal year ended June 30, 2021.

The following table presents dividends per share and dividends recognized for the year ended June 30, 2021:

	Year Ended June 30, 2021
Dividends per share	$	134.55
Dividends ($000)	9,583
Deemed dividends ($000)	508

The obligation to issue the shares of II-VI Series B-2 Convertible Preferred Stock is an embedded feature within the II-VI Series B-1 Convertible Preferred Stock that does not require bifurcation for separate accounting.

Common Stock Offering

On July 2, 2020, II-VI announced the pricing of an underwritten public offering of 9,302,235 shares of II-VI Common Stock at a public offering price of $43.00 per share, resulting in gross proceeds to II-VI from the offering of approximately $400 million, before deducting the underwriting discounts and commissions and offering expenses payable by II-VI (the “Common Stock Offering”). In addition, the underwriters had a 30-day option to purchase up to an additional 1,395,335 shares of II-VI Common Stock at the applicable public offering price, less underwriting discounts and commissions. On July 2, 2020, the underwriters exercised the option in full, raising an additional approximately $60 million in gross proceeds. On July 7, 2020, the Company closed the Common Stock Offering, including the issuance and sale of approximately 11 million shares II-VI Common Stock.

Note 12.        Earnings Per Share

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

The diluted earnings (loss) per common share is computed by dividing the diluted earnings (loss) available to 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 method. For the fiscal years ended 2021, 2020 and 2019, diluted shares outstanding include the

97

dilutive effect of the potential shares of the Company's common stock issuable from stock options, performance and restricted shares. For fiscal year ended 2021, the diluted shares outstanding also include the dilutive effect of the potential shares of the Company's Common Stock issuable upon conversion of outstanding convertible debt

The following is a reconciliation of the numerators and denominators of the basis and diluted earnings (loss) per share computations for the periods presented ($000):

Note 13.        Leases

We determine if an arrangement is a lease at inception and classify it as either finance or operating.

Finance leases are generally those that allow us to substantially utilize or pay for the entire asset over its estimated useful life. Finance leases are recorded in property, plant and equipment, net, and finance lease liabilities within other current and other non-current liabilities on our Consolidated Balance Sheet. Finance lease assets are amortized in operating expenses on a

98

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 the Company’s Consolidated Balance Sheet. Operating lease assets are amortized on a straight-line basis in operating expenses over the lease term.

The Company’s 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. The Company’s 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.

The Company’s 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.

Note 14.        Share-Based Compensation

The Company’s Board of Directors amended the II-VI Incorporated 2018 Omnibus Incentive Plan, which was approved by the shareholders at the Annual Meeting in November 2018. The Amended Omnibus Plan (the “Plan”) was approved at the annual meeting in November 2020. The Plan provides for the grant of non-qualified stock options, stock appreciation rights, restricted shares, restricted share units, deferred shares, performance shares and performance share units to employees, officers and directors of the Company. The maximum number of shares of the Company’s common stock authorized for issuance under the Plan is limited to 9,550,000 shares of common stock, not including any remaining shares forfeited under the predecessor plans that may be rolled into the Plan. The Plan has vesting provisions predicated upon the death, retirement or disability of the grantee.

As of June 30, 2021, there were approximately 8 million shares available to be issued under the Plan, including forfeited shares from predecessor plans.

The Company records share-based compensation expense for these awards, which requires the recognition of the grant-date fair value of share-based compensation in net earnings. The Company recognizes the share-based compensation expense over the requisite service period of the individual grantees, which generally equals the vesting period. The Company accounts for cash-based stock appreciation rights, cash-based restricted share units and cash-based performance share units as liability awards, in accordance with U.S. GAAP.

Share-based compensation expense for the fiscal years ended June 30, 2021, 2020 and 2019 is as follows $000:

Year Ended June 30,	2021		2020		2019
Stock Options and Cash-Based Stock    Appreciation Rights	$	10,626	$	11,893	$	6,801
Restricted Share Awards, Restricted Share    Units, and Cash-Based Restricted Share Units	47,060		49,957		9,242
Performance Share Units and Cash    Based Performance Share Units	16,640		11,977		8,920
	$	74,326	$	73,827	$	24,963

Stock Options and Cash-Based Stock Appreciation Rights:

The Company utilized the Black-Scholes valuation model for estimating the fair value of stock options and cash-based stock appreciation rights. During the fiscal year ended June 30, 2021, no stock options were issued. During fiscal years ended June 30, 2020 and 2019, the weighted-average fair value of options granted under the Plan was $14.79 and $20.66, respectively, per option using the following assumptions:

Year Ended June 30,	2020		2019
Risk-free interest rate	1.50	%	2.80	%
Expected volatility	39	%	37	%
Expected life of options	6.91 years		6.96 years
Dividend yield	None		None

100

The risk-free interest rate is derived from the average U.S. Treasury Note rate during the period, which approximates the rate in effect at the time of grant related to the expected life of the options. The risk-free interest rate shown above is the weighted average rate for all options granted during the fiscal year. Expected volatility is based on the historical volatility of the Company’s common stock over the period commensurate with the expected life of the options. The expected life calculation is based on the observed time to post-vesting exercise and/or forfeitures of options by our employees. The dividend yield of zero is based on the fact that the Company has never paid cash dividends and has no current intention to pay cash dividends in the future.

Stock option and cash-based stock appreciation rights activity during the fiscal year ended June 30, 2021 was as follows:

	Stock Options			Cash-Based Stock Appreciation Rights
	Number of Shares	Weighted Average Exercise Price		Number of Rights	Weighted Average Exercise Price
Outstanding - July 1, 2020	3,721,801	$	26.99	230,374	$	32.13
Exercised	(1,047,216)	$	21.04	(76,880)	$	28.75
Forfeited and Expired	(31,951)	$	33.86	(8,160)	$	34.14
Outstanding - June 30, 2021	2,642,634	$	29.26	145,334	$	33.80
Exercisable - June 30, 2021	1,805,735	$	25.31	63,209	$	27.36

As of June 30, 2021, 2020 and 2019, the aggregate intrinsic value of stock options and cash-based stock appreciation rights outstanding and exercisable was $88 million, $80 million and $56 million, respectively. Aggregate intrinsic value represents the total pretax intrinsic value (the difference between the Company’s 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, 2021. 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, 2021, 2020, and 2019 was $49 million, $20 million, and $15 million, respectively. As of June 30, 2021, total unrecognized compensation cost related to non-vested stock options and cash-based stock appreciation rights was $9 million. This cost is expected to be recognized over a weighted-average period of approximately two years.

Outstanding and exercisable stock options at June 30, 2021 were as follows:

	Stock Options and Cash-Based Stock Appreciation Rights Outstanding				Stock Options and Cash-Based Stock Appreciation Rights Exercisable
	Number of	Weighted Average Remaining	Weighted Average		Number of	Weighted Average Remaining	Weighted Average
Range of	Shares or	Contractual Term	Exercise		Shares or	Contractual Term	Exercise
Exercise Prices	Rights	(Years)	Price		Rights	(Years)	Price
$13.34 - $18.07	574,264	3.55	$	16.18	574,264	3.55	$	16.18
$18.07 - $24.35	685,719	4.01	$	20.83	674,952	3.94	$	20.70

	2,787,968	5.78	$	29.49	1,868,944	4.78	$	25.38

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.

Restricted share award, restricted share unit, and cash-based restricted share unit activity during the fiscal year ended June 30, 2021, was as follows:

101

	Restricted Share Awards			Restricted Share Units			Cash-Based Restricted Share Units
	Number of Shares	Weighted Average Grant Date  Fair Value		Number of Units	Weighted Average Grant Date Fair Value		Number of Units	Weighted Average Grant Date Fair Value
Nonvested - June 30, 2020	50,527	$	35.92	2,242,412	$	39.46	82,003	$	38.31
Granted	—	$	—	1,277,460	$	45.74	5,194	$	44.30
Vested	(49,525)	$	35.47	(996,955)	$	37.91	(38,943)	$	38.57
Forfeited	(1,002)	$	18.42	(196,745)	$	38.36	(2,381)	$	38.91
Nonvested - June 30, 2021	—	$	—	2,326,172	$	43.67	45,873	$	38.75

As of June 30, 2021, total unrecognized compensation cost related to non-vested, restricted share unit and cash-based restricted share units was $68 million. This cost is expected to be recognized over a weighted-average period of approximately two years. The restricted share award and 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, 2021, 2020 and 2019, was $59 million, $11 million and $10 million, respectively. The total fair value of restricted share awards, restricted share units and cash-based restricted share units vested was $69 million, $75 million and $20 million during fiscal years 2021, 2020 and 2019, respectively.

Performance Share Units and Cash-Based Performance Share Units:

The Compensation Committee of the Board of Directors of the Company has granted certain executive officers and employees performance share units and cash-based performance share units under the Plan. As of June 30, 2021, the Company 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. The cash-based performance 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. Performance share unit and cash-based performance share unit activity relating to the Plan during the year ended June 30, 2021, was as follows:

102

	Performance Share Units			Cash-Based Performance Share Units
	Number of Units	Weighted Average Grant Date Fair Value		Number of Units	Weighted Average Grant Date Fair Value
Nonvested - June 30, 2020	409,246	$	40.96	35,188	$	38.54
Granted	209,639	$	52.04	—	$	—
Vested	(187,410)	$	30.03	(14,928)	$	35.25
Forfeited	(5,344)	$	37.66	—	$	—
Performance Adjustments	92,178	$	17.52	7,464	$	35.25
Nonvested - June 30, 2021	518,309	$	45.28	27,724	$	39.43

As of June 30, 2021, total unrecognized compensation cost related to non-vested performance share units and cash-based performance share units was $12 million. This cost is expected to be recognized over a weighted-average period of approximately 1.65 years. The total fair value of the performance share units and cash-based performance share units granted during the fiscal years ended June 30, 2021, 2020 and 2019 was $14 million, $15 million and $10 million, respectively. The total fair value of performance share units and cash-based performance share units vested during the fiscal years ended June 30, 2021, 2020 and 2019 was $9 million, $6 million and $11 million, respectively. The performance adjustments relate to grants that exceeded the performance targets when vested during FY21, including the final number of shares issued, which were 200% of the target units based on actual results during the three-year performance period.

Note 15.        Segment and Geographic Reporting

The Company reports its business segments using the “management approach” model for segment reporting. This means that the Company determines its reportable business segments based on the way the chief operating decision maker organizes business segments within the Company for making operating decisions and assessing performance.

The Company reports its financial results in two segments, and the Company’s chief operating decision maker receives and reviews financial information based on these segments.  The Company evaluates business segment performance based upon segment operating income, which is defined as earnings before income taxes, interest and other income or expense.

The Compound Semiconductors segment has locations in the United States, Singapore, China, Germany, Switzerland, Japan, Belgium, the United Kingdom, Italy, South Korea, the Philippines, Vietnam, Sweden, and Taiwan. This segment address all of II-VI's seven end markets, namely: communications, industrial, aerospace & defense, consumer electronics, semiconductor capital equipment, life sciences and automotive. This segment designs, manufactures and markets the following products: (i) optical and electro-optical components and materials used primarily in CO2 lasers, fiber-lasers and direct diode lasers for materials processing applications; (ii) infrared optical components and high-precision optical assemblies for aerospace and defense, medical and commercial laser imaging applications; (iii) semiconductor lasers and detectors for optical interconnects and sensing applications; (iv) engineered materials for thermoelectric, ceramics and silicon carbide for a wide range of applications; and (v) compound semiconductor epitaxial wafers for applications in optical and wireless communication.

The Photonic Solutions segment has locations in the United States, China, Vietnam, Germany, Japan, the United Kingdom, Italy, Malaysia, Australia, and Hong Kong. This segment manufactures (i) transceivers for data centers and telecom optical networks; (ii) pump lasers, optical amplifiers, wavelength selective switches and advanced components for telecom networks; (iii) crystal materials, optics, lasers and optoelectronic modules for a wide range of applications, including in optical communications, life sciences, and consumer electronics markets.

In September 2019, the Company completed its acquisition of Finisar. The operating results of this acquisition have been reflected in the selected financial information of the Company’s Photonic Solutions segment and Compound Semiconductors Segment beginning on October 1, 2019, with the results from September 24, 2019 to September 30, 2019 reflected in Unallocated and Other.

The accounting policies are consistent across both of the segments. To the extent possible, the Company’s corporate expenses are allocated to the segments. The Company evaluates segment performance based upon reported segment operating income, which is defined as earnings from continuing operations before income taxes, interest and other income or expense. Unallocated and Other include eliminating inter-segment sales and transfers as well as transaction costs related to the pending Coherent

103

acquisition in the fiscal year ended June 30, 2021. In the fiscal year ended June 30, 2020, it included transaction costs related to the Finisar acquisition.

Note 16.        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. The Company estimates fair value of its 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.

The Company entered into an interest rate swap with a notional amount of $1,075 million to limit the exposure to its variable interest rate debt by effectively converting it to a fixed interest rate. The Company receives payments based on the one-month LIBOR and makes payments based on a fixed rate of 1.52%. The Company receives payments with a floor of 0.00%. The interest rate swap agreement has an effective date of November 24, 2019, with an expiration date of September 24, 2024. The initial notional amount of the interest rate swap is scheduled to decrease to $825 million in June 2022 and will remain at that amount through the expiration date. The Company designated this instrument as a cash flow hedge and deemed the hedge relationship effective at inception of the contract. The fair value of the interest rate swap of $29 million is recognized in the Consolidated Balance Sheet within other accrued liabilities (current) and other liabilities (non-current). Changes in fair value are recorded within accumulated other comprehensive income (loss) on the Consolidated Balance Sheet and reclassified into the Consolidated Statements of Earnings (Loss) as interest expense in the period in which the underlying transaction affects earnings. Cash flows from hedging activities are reported in the Consolidated Statements of Cash Flows in the same classification as the hedged item, generally as a component of cash flows from operations. The fair value of the interest rate swap is determined using widely accepted valuation techniques and reflects the contractual terms of the interest rate swap including the period to maturity, and while there are no quoted prices in active markets, it uses observable market-based inputs,

106

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 interest rate swap is classified as a Level 2 item within the fair value hierarchy.

The Company estimated the fair value of the II-VI Notes and Finisar Notes based on quoted market prices as of the last trading day prior to June 30, 2021; however, the II-VI Notes and Finisar Notes have only a limited trading volume and as such this fair value estimate is not necessarily the value at which the II-VI Notes and Finisar Notes could be retired or transferred. The Company concluded that this fair value measurement should be categorized within Level 2. The carrying value of the II-VI Notes and Finisar Notes is net of unamortized discount and issuance costs. See Note 9. Debt for details on the Company’s debt facilities.

The fair value and carrying value of the II-VI Notes and Finisar Notes were as follows at June 30, 2021 ($000):

	Fair Value		Carrying Value
II-VI Notes	$	549,580	$	328,032
Finisar Notes	$	14,889	$	14,888

The fair values of 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. The Company’s borrowings including its lease obligations, excluding the 0.25% Convertible Notes and the 0.50% Finisar convertible notes, are considered Level 2 among the fair value hierarchy and their principal amounts approximate fair value.

By entering into the Investment Agreement as described in Note 3 on March 25, 2021, the Company entered into a commitment to issue shares of II-VI Series B-1 Convertible Preferred Stock on the Initial Closing Date for a fixed price (such commitment the "Forward Sale Commitment"). The Forward Sale Commitment comprises a financial instrument, other than an outstanding share, that, at inception, has both of the following characteristics: (i) embodies an obligation to repurchase the Company's equity shares and (ii) requires or may require the Company to settle the obligation by transferring assets. Under ASC 480, Distinguishing Liabilities from Equity, it is required to be initially measured and subsequently remeasured, at fair value as an asset or liability with changes in fair value recognized in earnings. An option pricing model was utilized to calculate the fair value of the Forward Sale Commitment. The Company recognized $11 million of realized gains within Other Expense (Income), Net in the Consolidated Statements of Earnings (Loss) for the year ended June 30, 2021, related to the Forward Sale Commitment due to changes in its fair value from March 25, 2021 to its settlement on March 31, 2021.

The Company, from time to time, purchases foreign currency forward exchange contracts, that permit it to sell specified amounts of these foreign currencies expected to be received from its export sales, for pre-established U.S. dollar amounts at specified dates. These contracts are entered into to limit transactional exposure to changes in currency exchange rates of export sales transactions in which settlement will occur in future periods and which otherwise would expose the Company, on the basis of its aggregate net cash flows in respective currencies, to foreign currency risk.

Note 17.        Employee Benefit Plans

Eligible U.S. employees of the Company participate in a profit sharing retirement plan. Contributions accrued for the plan are made at the discretion of the Company’s board of directors and were $2 million, $6 million, and $5 million for the years ended June 30, 2021, 2020 and 2019, respectively.

On August 18, 2018, the Company adopted the 2018 Employee Stock Purchase Plan (“2018 Plan”) for full time U.S. employees who have completed two years of continuous employment with the Company, and the 2018 Plan was approved by the Company’s shareholders at the Company’s Annual Meeting of Shareholders in November 2018. The employee may purchase the Company’s common stock for the lesser of 90% of the fair market value of the shares (i) on the first trading day of the offering period, or (ii) on the purchase date. Offering periods will run from August through January and from February through July each year. The number of shares which may be bought by an employee during each fiscal year is limited to 15% of the employee’s base pay. The 2018 Plan limits the number of shares of common stock available for purchase to 2,000,000 shares. As of June 30, 2021, there have been 361,834 shares purchased on behalf of the employees under the 2018 Plan.

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

107

employee age and other factors. Employer contributions to the Swiss Plan for years ended June 30, 2021 and 2020 were $4 million and $3 million, respectively. Net periodic pension cost is not material for any year presented.

The underfunded pension liability was $25 million and $27 million as of June 30, 2021 and 2020, respectively. The pension adjustment amount recognized in accumulated other comprehensive income was $2 million decrease and $3 million increase for the fiscal years ended June 30, 2021 and 2020, respectively. The accumulated benefit obligation was $90 million as of June 30, 2021, compared to $85 million as of June 30, 2020.

Estimated future benefit payments under the Swiss Plan are estimated to be as follows:

Year Ending June 30,
($000)
2022	$	5,500
2023	4,700
2024	4,900
2025	6,100
2026	7,500

Note 19.        Commitments and Contingencies

The Company has 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 the Company’s materials and processes, certain contracts may contain liquidated damage provisions for early termination. The Company does 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. The Company also has contingent obligations relating to earnout arrangements on its acquisitions of $1 million. Total future purchase commitments held by II-VI as of June 30, 2021, were $352 million in fiscal 2022, and $35 million thereafter.

Note 20.        Share Repurchase Programs

In August 2014, the Company’s Board of Directors authorized the Company to purchase up to $50 million of its common stock through a share repurchase program (the “Program”) that calls for shares to be purchased in the open market or in private transactions from time to time. The Program has no expiration and may be suspended or discontinued at any time. Shares purchased by the Company are retained as treasury stock and available for general corporate purposes. The Company did not repurchase any shares pursuant to this Program during the fiscal year ended June 30, 2021. During the fiscal

year ended June 30, 2020 the Company purchased 50,000 shares of its common stock for $2 million

under this program. As of June 30, 2021, the Company has cumulatively purchased 1,416,587 shares of II-VI common stock pursuant to the Program for approximately $22 million.

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) as of the end of the period covered by this Annual Report on Form 10-K.

Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2021, the Company’s disclosure controls and procedures are effective.

Exhibit 10.20

II‑VI Incorporated Performance Unit SETTLED IN shares

AWARD AGREEMENT

THIS PERFORMANCE UNIT AWARD AGREEMENT, including any general and jurisdiction-specific terms and conditions for the Recipient’s jurisdiction set forth in the appendices attached hereto, (this “Agreement”) is dated as of the Grant Date, as specified in the applicable Employee Grant Details (as defined below), by and between II‑VI Incorporated, a Pennsylvania corporation (“II‑VI”), and the Recipient, as specified in the applicable Employee Grant Details, who is a director, employee or consultant of II‑VI or one of its Subsidiaries (the “Recipient”).

Reference is made to the Employee Grant Details (the “Employee Grant Details”) issued to the Recipient with respect to the applicable Award, which may be found on the Solium Shareworks system at https://Shareworks.Solium.com (or any successor system selected by II-VI) (the “Solium Shareworks System”). Reference further is made to the prospectus relating to the Plan (as defined below), which also may be found on the Solium Shareworks System.

All capitalized terms used herein, to the extent not defined herein, shall have the meanings set forth in the II‑VI 2012 Omnibus Incentive Plan (as amended and/or restated from time to time, the “Plan”), a copy of which can be found on the Solium Shareworks System, and/or the applicable Employee Grant Details. Terms of the Plan and the Employee Grant Details are incorporated herein by reference. This Agreement shall constitute an Award Agreement as that term is defined in the Plan.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, and intending to be legally bound hereby, the Recipient and II-VI agree as follows:

1.Performance Unit Award. II-VI hereby grants to the Recipient an Award of Performance Units under the Plan, as specified in the Employee Grant Details, to be earned based upon achievement of the Performance Objectives in accordance with Section 2 and Section 3 (this “Award”). For the purposes of this Award: (1) “Performance Period” shall mean the period from July 1, 2018 through and including June 30, 2021;(2) “Target Award” shall mean the Target Award set forth in the Employee Grant Details; and (3) “Maximum Award” means the maximum number of Performance Units allowable under this Agreement as set forth in the Employee Grant Details representing 200% of the Target Award.

2.Determination of Units Earned/Shares Delivered. Subject to Section 5 and Section 6,The Performance Units shall be subject to a series of performance evaluations for Cash Flow from Operations and Relative Total Shareholder Return (TSR) (the “Performance Measures”). The number of Performance Units that can potentially be earned/vested (i.e., credited) is evaluated based on the Corporation’s Cash Flow from Operations performance (as such term is defined below), and may then be subject to potential modification based upon Relative TSR Modifier results (as such term is defined below).

	Performance Units Earned as a Percentage of Target Award
If II-VI Consolidated Cash Flow from Operations is less than 74.99% of the Cash Flow Target	—%
If II-VI Consolidated Cash Flow from Operations is greater than or equal to 75.00% and less than 100.0% of the Cash Flow Target	50.0% to 99.99%(1)
If II-VI Consolidated Cash Flow from Operations equals 100.0% of the Cash Flow Target	100%
If II-VI Consolidated Cash Flow from Operations is greater than 100.0% and less than 140.0% of the Cash Flow Target	100.01% to 199.99%(2)
If II-VI Consolidated Cash Flow from Operations is greater than or equal to 140.0% of the Cash Flow Target	200.0% (Maximum Award)

Exhibit 10.20

(1) In the event that the II-VI Consolidated Cash Flow from Operations is greater than or equal to 75.0% and less than 100.0% of the Cash Flow Target, the Performance Units earned as a percentage of the Target Award will be a percentage determined on a linear basis between 50.0% and 99.99% by adding 50.0% to the product of (A) 50.0% and (B)(i) the II-VI Consolidated Cash Flow from Operations as a percentage of the Cash Flow Target less 75.0% divided by (ii) 25.0% (which product cannot exceed 49.99%).

(2) In the event that the II-VI Consolidated Cash Flow from Operations is greater than 100.0% and less than 140.0% of the Cash Flow Target, the Performance Units earned as a percentage of the Target Award will be a percentage determined on a linear basis between 100.01% and 199.99% by adding 100.0% to the product of (A) 100.0% and (B)(i) the II-VI Consolidated Cash Flow from Operations as a percentage of the Cash Flow Target less 100.0% divided by (ii) 40.0% (which product cannot exceed 99.99%).

For the purposes of this Award: (i) “II-VI Consolidated Cash Flowfrom Operations” shall mean the “Total Cash Flow” of II-VI for the Performance Period, determined in accordance with generally accepted accounting principles in the United States, consistently applied; (ii) all targets are expressed in US dollars and performance for II-VI businesses that do not use US dollars as their reporting currency will be translated into US dollars via II-VI’s financial consolidation system at the appropriate exchange rates; and (iii) “Cash Flow Target” shall mean $717,328,000.00.

3.Relative TSR Modifier. The Performance Units to be credited from Cash Flow from Operations results for the Performance Period are subject to a potential Relative TSR Modifier. The TSR performance of II-VI will be measured against the components of Russell 2000 Index. If TSR performance is aligned with the 75th percentile TSR performance of the Russell 2000 Index, the Performance Units credited based on the Cash Flow from Operations results will be multiplied by 125%. For every two percentage points below the 75th percentile TSR of the Russell 2000 Index, the multiplier will be reduced by 1% to a minimum of 100% and for every two percentage points above the 75th percentile TSR of the Russell 2000 Index, the multiplier will be increased by 1%. If II-VI’s TSR is negative for the three-year performance period, the multiplier will be fixed at 100%. See the table below for further illustration.

	Multiplier Applied to Performance Units Earned based on Cash Flow from Operations
If Cumulative TSR is equal to or more than 50 percentage points below Market 75th Percentile or there is an absolute negative Cumulative TSR	100%
If Cumulative TSR is below Market 75th Percentile by less than 50 percentage points and there is an absolute positive Cumulative TSR	Subtract 1% from 125% for each 2% below Market 75th Percentile
If Cumulative TSR equals Market 75th Percentile	125%
If Cumulative TSR is above Market 75th Percentile by less than 50 percentage points	Add 1% to 125% for each 2% above Market 75th Percentile
If Cumulative TSR is above Market 75th Percentile by more than 50 percentage points	150%

Definitions:

“Market” is the Russell 2000 as published on June 26, 2018. If a listing is removed from the Russell 2000 during the Performance Period, it will not be replaced, nor will any listing be added for any other reason. The Russell 2000 shall be a closed group for purposes of this Program.

“Cumulative TSR” shall be based on the 30-day average closing stock price of the Shares prior to July 1, 2018 ($46.58) (“Beginning Stock Price”) and the 30 day average closing stock price of the Shares prior to July 1, 2021 (“Ending Stock Price”). Cumulative TSR shall be calculated as follows:

Exhibit 10.20

((Ending Stock Price minus Beginning Stock Price ($46.58) plus dividends) divided by Beginning Stock Price ($46.58))

4.Payment; Dividend Equivalents. The amount determined under Section 2 and Section 3 will be paid to the Recipient in Shares no later than the seventy fifth (75th) calendar day following the end of the Performance Period. In addition, the Recipient shall be entitled to receive, following the completion of the Performance Period but in no event later than March 15th of the calendar year following the completion of the Performance Period, a cash payment equal to the cash dividends that would have been paid during the Performance Period on the applicable number of Shares underlying the Performance Units earned as provided in Section 2 and Section 3 if such Shares had been issued and outstanding during the Performance Period. Notwithstanding the foregoing, the Company, at its sole discretion, may settle the Award in cash if necessary or appropriate for legal or administrative reasons based on laws in the Recipient’s jurisdiction, in which case the Company shall pay to the Recipient an amount in cash equal to the product of (a) the number of Performance Units earned in accordance with Section 2 and Section 3 and (b) the Fair Market Value on the day prior to the Committee’s approval of the number of Performance Units earned following completion of the Performance Period, with such cash payment being made to the Recipient no later than the seventy fifth (75th) calendar day following the end of the Performance Period.

5.Separation from Service.

(a) Except as provided in Section 5(b) or Section 6 or as may be otherwise determined by the Committee, if the Recipient incurs a Separation from Service before the end of the Performance Period, this Award shall be forfeited on the date of such Separation from Service.

(b) Prorating in Certain Circumstances. Notwithstanding Section 5(a), if the Recipient’s Separation from Service occurs during the Performance Period due to the Recipient’s (i) normal retirement, as defined in II-VI’s Global Retirement Policy, (ii) death, (iii) permanent and total disability, as defined in Code Section 22(e)(3) (a “Disability”), (iv) termination by the Company or a Subsidiary that the Recipient is employed by or provides services to (the “Employer”) other than for Cause (as defined below) other than within two years following a Change in Control or (v) termination by the Recipient for Good Reason (as defined below) other than within two years following a Change in Control, but only if the Recipient’s offer letter, employment agreement or other applicable employment or service agreement with the Company or the Employer provides for severance upon Separation from Service for Good Reason (or a similar term), then in each case under clauses (i) - (v) of this paragraph the Recipient shall be entitled to a prorated portion of the Performance Units to the extent earned pursuant to Section 2 and Section 3, determined at the end of the Performance Period and based on the ratio of the number of complete months the Recipient was employed or served (as applicable) during the Performance Period to the total number of months in the Performance Period. In the event of the death of the Recipient, amounts due pursuant to Section 2 and Section 3 shall be paid to the Recipient’s estate as soon as administratively practicable after the end of the Performance Period.

Notwithstanding any provision of this Agreement, if the Company receives a legal opinion that, due to a legal judgment and/or development in the Recipient’s jurisdiction, the potential pro-rated vesting that applies to this Award upon a Recipient’s normal retirement would be deemed unlawful or discriminatory, the provisions of this Section 5(b)(i) regarding the vesting of this Award if the Recipient’s Separation from Service is as a result of normal retirement will not be applicable to the Recipient and the remaining provisions of this Agreement will govern.

6.Change in Control; Adjustments to Payments.

(a) Change in Control. Notwithstanding any provision to the contrary in this Agreement or in any offer letter, employment agreement or other applicable employment or service agreement between the Recipient and the Company or the Employer that discusses the effect of a Change in Control on the Recipient’s Awards, in the event of a Change in Control during the Performance Period, the following provisions shall apply, unless provided otherwise by the Committee prior to the date of the Change in Control:

Exhibit 10.20

(i) To the extent this Award is assumed, converted or replaced by the resulting entity in the Change in Control, if within two (2) years after the date of the Change in Control the Recipient has a Separation from Service either (A) by the Company or the Employer other than for Cause (as defined below) or (B) by the Recipient for Good Reason (as defined below), then the target payout opportunities attainable under this Award shall be deemed to have been earned as of the applicable Separation from Service based upon the greater of: (1) an assumed achievement of all relevant performance goals at their “target” level, or (2) the actual level of achievement of all relevant performance goals against target as of the Company’s fiscal quarter end preceding the Change in Control. This Award, as adjusted for such deemed performance, shall become vested in full and shall be paid as soon as administratively practicable (not more than thirty (30) days) after the date of such Separation from Service.

(ii) To the extent this Award is not assumed, converted or replaced by the resulting entity in the Change in Control, then the target payout opportunities attainable under this Award shall be deemed to have been earned as of the Change in Control based upon the greater of: (1) an assumed achievement of all relevant performance goals at their “target” level, or (2) the actual level of achievement of all relevant performance goals against target as of the Company’s fiscal quarter end preceding the Change in Control. This Award, as adjusted for such deemed performance, shall become vested in full and shall be paid as soon as administratively practicable (not more than thirty (30) days) after the date of such Change in Control.

(b) “Cause” shall be defined as that term is defined in the Recipient’s offer letter, employment agreement or other applicable employment or service agreement with the Company; or, if there is no such definition, “Cause” shall mean a determination by the Company that any of the following has occurred:

(i) the willful failure by the Recipient to perform the Recipient’s duties and responsibilities to the Company or the Employer (other than any such failure resulting from the Recipient’s Disability), which is not cured within ten (10) business days of receiving written notice from the Company or the Employer specifying in reasonable detail the duties or responsibilities that the Company or the Employer believes are not being adequately performed;

(ii) the willful engaging by the Recipient in any act that is damaging to the Company or the Employer;

(iii) the conviction of the Recipient of, or a plea of “guilty” or “no contest” to, (A) any felony or (B) a criminal offense involving fraud, dishonesty or other moral turpitude;

(iv) any breach by the Recipient of the terms of any written agreement between the Recipient and the Company relating to proprietary information, confidentiality, non-disclosure, ownership of inventions, non-competition, non-solicitation, non-interference or non-disparagement;

(v) the engaging by the Recipient in any willful act of dishonesty resulting or intended to result, directly or indirectly, in personal gain to the Recipient; or

(vi) the commission of any act by the Recipient that is in violation of the Company’s Code of Business Conduct and Ethics.

(c) “Good Reason” shall be defined as that term is defined in the Recipient’s offer letter, employment agreement or other applicable employment or service agreement with the Company; or, if there is no such definition, “Good Reason” shall mean that any of the following has occurred, without the Recipient’s express written consent:

(i) a material reduction of the Recipient’s employment responsibilities from those immediately prior to the Change in Control;

(ii) a material reduction by the Company or the Employer of the Recipient’s eligibility for Total Target Compensation as in effect immediately prior to the Change in Control, with “Total Target Compensation” defined as the Recipient’s annual base salary plus the cash and stock compensation the Recipient is eligible to receive from the Company or the Employer at one hundred percent (100%) performance, whether sales incentive, bonus or otherwise;

Exhibit 10.20

(iii) a material increase in the amount of the Recipient’s business travel that produces a constructive relocation of the Recipient;

(iv) a material reduction by the Company or the Employer in the kind or level of employee benefits to which the Recipient is entitled immediately prior to the Change in Control, with the result that the Recipient’s overall benefits package is materially reduced; or

(v) the relocation of the Recipient to a facility or a location more than thirty (30) miles from the Recipient’s principal place of employment immediately prior to the Change in Control.

In order for the Recipient to incur a Separation from Service for Good Reason, (A) the Company must be notified by the Recipient in writing within ninety (90) days of the event constituting Good Reason, (B) the event must remain uncorrected by the Company or the Employer (as applicable) for thirty (30) days following such notice (the “Notice Period”), and (C) such Separation from Service must occur within sixty (60) days after the expiration of the Notice Period.

(d) Adjustments to Payments.

(i) Notwithstanding any provision to the contrary in this Agreement, if it is determined that any payment or distribution by the Company or the Employer to the Recipient or for the Recipient’s benefit (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise) (the “Payments”) would be subject to the excise tax imposed by Code Section 4999, or any interest or penalty is incurred by the Recipient with respect to such excise tax (such excise tax, together with any such interest and penalties, collectively referred to as the “Excise Tax”), then the Payments shall be reduced (but not below zero) if and to the extent that such reduction would result in the Recipient retaining a larger amount, on an after-tax basis (taking into account federal, state and local income taxes and the imposition of the Excise Tax), than if the Recipient received all of the Payments. The Payments shall be reduced or eliminated by first reducing or eliminating the portion of the Payments that are not payable in cash and then by reducing or eliminating cash payments, in each case in reverse order beginning with payments or benefits that are to be paid the farthest in time from the determination.

(ii) All determinations required to be made under this Section 6(d), including whether and when an adjustment to any Payments is required and, if applicable, which Payments are to be so adjusted, shall be made by an independent accounting firm selected by II-VI from among the four (4) largest accounting firms in the United States or any nationally-recognized financial planning and benefits consulting company (the “Accounting Firm”), which shall provide detailed supporting calculations both to II-VI and to the Recipient within fifteen (15) business days of the receipt of notice from the Recipient that there has been a Payment, or such earlier time as is requested by II-VI. In the event that the Accounting Firm is serving as accountant or auditor for the individual, entity or group effecting the Change in Control, II-VI shall appoint another nationally-recognized accounting firm to make the determinations required hereunder (which accounting firm shall then be referred to as the Accounting Firm hereunder). All fees and expenses of the Accounting Firm shall be borne solely by II-VI. If the Accounting Firm determines that no Excise Tax is payable by the Recipient, it shall furnish the Recipient with a written opinion that failure to report the Excise Tax on the Recipient’s applicable federal income tax return would not result in the imposition of a negligence or similar penalty. Any determination by the Accounting Firm shall be binding upon the Company and the Recipient.

7.Nontransferability. Except as otherwise provided in the Plan, the Performance Units shall not be sold, pledged, assigned, hypothecated, transferred or disposed of (a “Transfer”) in any manner, other than by will or the laws of descent and distribution. Any attempt to Transfer the Performance Units in violation of this Section or the Plan shall render this Award null and void.

8.Adjustments. Upon any event described in Section 12 of the Plan (entitled “Adjustments”) or any successor provision thereto, the terms of such Section 12 of the Plan or any successor provision thereto shall apply to this Award.

9.Fractional Shares. II-VI shall not be required to issue any fractional Shares pursuant to this Award, and II-VI may round fractional Shares down to the nearest whole Share.

10.Responsibility for Taxes.

Exhibit 10.20

(a) Regardless of any action the Company or the Employer takes with respect to any or all income tax, social insurance, payroll tax, fringe benefit tax, payment on account or other tax-related items related to the Recipient’s participation in the Plan (“Tax-Related Items”), the Recipient acknowledges that the ultimate liability for all Tax-Related Items owed by the Recipient is and remains the Recipient’s responsibility and that the Company (i) makes no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of this Award, including the grant or vesting of this Award or the subsequent sale of Shares acquired pursuant to this Award; and (ii) does not commit to structure the terms of the grant or any aspect of this Award to reduce or eliminate the Recipient’s liability for Tax-Related Items or achieve a particular tax result. Further, if the Recipient is subject to Tax-Related Items in more than one jurisdiction, the Recipient acknowledges and agrees that the Company or the Employer may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

(b) Prior to any relevant taxable or tax withholding event, as applicable the Recipient agrees to make adequate arrangements satisfactory to the Company to satisfy all Tax-Related Items. In this regard, the Recipient authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy any applicable withholding obligations with regard to Tax-Related Items by one or a combination of the following: (i) withholding from the Recipient’s wages or other cash compensation paid to the Recipient by the Company or the Employer; (ii) withholding from the proceeds of the sale of Shares acquired upon vesting of this Award either through a voluntary sale or through a mandatory sale arranged by the Company (on the Recipient’s behalf pursuant to this authorization) without further consent; (iii) withholding Shares to be issued upon vesting of this Award; or (iv) any other method determined by the Committee and permitted by applicable laws. Notwithstanding the foregoing, if the Recipient is subject to the short-swing profit rules of Section 16(b) of the Exchange Act, the Company will withhold in Shares issuable at vesting of the Award upon the relevant withholding event, unless otherwise determined by the Committee.

(c) The Company may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding amounts or other applicable withholding rates, including maximum applicable rates, in which case the Recipient may receive a refund of any over-withheld amount in cash (with no entitlement to the equivalent in Shares), or, if not refunded, the Recipient may seek a refund from the local tax authorities. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, the Recipient is deemed to have been issued the full number of Shares, notwithstanding that a number of Shares are held back solely for the purpose of paying the Tax-Related Items.

(d) Finally, the Recipient shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of the Recipient’s participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to issue or deliver Shares or the proceeds from the sale of Shares, if the Recipient fails to comply with the Recipient’s obligations in connection with the Tax-Related Items, as described in this Section 10.

11.Plan Provisions. In the event of any conflict between the provisions of this Agreement and the Plan, the Plan shall control, except that capitalized terms specifically defined in this Agreement shall have the meaning given to them in this Agreement with respect to their usage in this Agreement, notwithstanding the definitions given to such terms in the Plan (which definitions shall control as they relate to the usage of such terms in the Plan).

12.No Continued Rights. The granting of this Award shall not give the Recipient any rights to similar grants in future years or any right to continuance of employment or other service with II-VI or its Subsidiaries, nor shall it interfere in any way with any right that the Company or the Employer would otherwise have to terminate the Recipient’s employment or other service at any time, or the right of the Recipient to terminate his or her employment or other service at any time.

13.Rights Unsecured. The Recipient shall have only II-VI’s unfunded, unsecured promise to pay pursuant to the terms of this Agreement. The rights of the Recipient hereunder shall be that of a general unsecured creditor of II-VI and the Recipient shall not have any security interest in any assets of II-VI.

14.Non-Competition; Non-Solicitation; Confidentiality.

Exhibit 10.20

(a) While the Recipient is employed by the Company (including its Subsidiaries) and for a period of one (1) year after the Recipient’s Separation from Service for any reason (the “Restricted Period”), the Recipient will not directly or indirectly:

(i) engage in any business or enterprise (whether as owner, partner, officer, director, employee, consultant, investor, lender or otherwise, except as the holder of not more than one percent (1%) of the outstanding stock of a publicly-held company), that develops, manufactures, markets or sells any product or service that competes with any product or service developed, manufactured, marketed or sold or, to the Recipient’s knowledge, planned to be developed, manufactured, marketed or sold, by II-VI or its Subsidiaries while the Recipient was employed by the Company or a Subsidiary, within the United States of America and/or any other country within which II-VI or its Subsidiaries have customers or prospective customers as of the date of such Separation from Service.

(ii) (A) solicit for the purpose of selling or distributing any products or services that are the same or similar to those developed, manufactured, marketed or sold by II-VI or its Subsidiaries, (1) any customers of II-VI or its Subsidiaries, (2) any prospective customers known by the Recipient to have been solicited by II-VI or its Subsidiaries within the twelve (12) months prior to the Recipient’s Separation from Service, or (3) any distributors, sales agents or other third-parties who sell to or refer potential customers in need of the types of products and services produced, marketed, licensed, sold or provided by II-VI or its Subsidiaries who have become known to the Recipient as a result of his/her employment with the Company (including its Subsidiaries), or (B) induce or attempt to induce any vendor, supplier, licensee or other business relation of II-VI or its Subsidiaries to cease or restrict doing business with II-VI or its Subsidiaries, or in any way interfere with the relationship between any such vendor, supplier, licensee or business relation and II-VI or its Subsidiaries.

(iii) either alone or in association with others (A) solicit, or permit any organization directly or indirectly controlled by the Recipient to solicit, any employee of II-VI or its Subsidiaries to leave the employ of II-VI or its Subsidiaries, or (B) solicit for employment, hire or engage as an independent contractor, or permit any organization directly or indirectly controlled by the Recipient to solicit for employment, hire or engage as an independent contractor, any person who was employed by II-VI or its Subsidiaries at any time during the term of the Recipient’s employment with the Company or a Subsidiary; provided that this clause (B) shall not apply to any individual whose employment with II-VI or its Subsidiaries has been terminated for a period of one year or longer.

(b) The Recipient acknowledges that certain materials, including information, data, technology and other materials relating to customers, programs, costs, marketing, investment, sales activities, promotion, credit and financial data, manufacturing processes, financing methods, plans or the business and affairs of II-VI and its Subsidiaries constitute proprietary confidential information and trade secrets. Accordingly, the Recipient will not at any time during or after the Recipient’s employment with the Company or a Subsidiary disclose or use for the Recipient’s own benefit or purposes or the benefit or purposes of any other person, firm, partnership, joint venture, association, corporation or other business organization, entity or enterprise, other than the Company (including its Subsidiaries), any proprietary confidential information or trade secrets; provided that the foregoing shall not apply to information which is not unique to II-VI and its Subsidiaries or which is generally known to the industry or the public other than as a result of the Recipient’s breach of this covenant. The Recipient agrees that, upon the Recipient’s Separation from Service for any reason, the Recipient will immediately return to II-VI all property of II-VI and its Subsidiaries including all memoranda, books, technical and/or lab notebooks, customer product and pricing data, papers, plans, information, letters and other data, and all copies thereof or therefrom, which in any way relate to the business of II-VI and its Subsidiaries, except that the Recipient may retain personal items. The Recipient further agrees that the Recipient will not retain or use for the Recipient’s account at any time any trade names, trademark or other proprietary business designation used or owned in connection with the business of II-VI and its Subsidiaries.

Exhibit 10.20

(c) The Restricted Period will be tolled during and for any period of time during which the Recipient is in violation of the restrictive covenants contained in this Section 14 and for any period of time which may be necessary to secure an order of court or injunction, either preliminary or permanent, to enforce such covenants, such that the cumulative time period during which the Recipient is in compliance with the restrictive covenants contained in Section 14 will not exceed the one (1)-year period set forth above.

(d) Nothing herein is intended to or shall limit, prevent, impede or interfere with the Recipient’s non-waivable right, without prior notice to the Company, to provide information to the government, participate in investigations, testify in proceedings regarding the Company’s past or future conduct, or engage in any activities protected under whistleblower statutes, or to receive and fully retain a monetary award from a government-administered whistleblower award program for providing information directly to a government agency. Further, the Recipient understands that pursuant to the Defend Trade Secrets Act of 2016, the Recipient shall not be held criminally, or civilly, liable under any Federal or State Trade secret law for the disclosure of a trade secret that is made in confidence either directly or indirectly to a Federal, State, or local government official, or an attorney, for the sole purpose of reporting, or investigating, a violation of law. Moreover, the Recipient understands that he or she may disclose trade secrets in a complaint, or other document, filed in a lawsuit, or other proceeding, if such filing is made under seal. Finally, the Recipient understands that if he or she

files a lawsuit alleging retaliation by the Company for reporting a suspected violation of the law, the Recipient may disclose the trade secret to the attorney and use the trade secret in the court proceeding.

15.Remedies; Clawback.

(a) II-VI and the Recipient acknowledge and agree that that any violation by the Recipient of any of the restrictive covenants contained in Section 14 would cause immediate, material and irreparable harm to II-VI and its Subsidiaries which may not adequately be compensated by money damages and, therefore, II-VI and its Subsidiaries shall be entitled to injunctive relief (including one (1) or more preliminary injunctions and/or ex parte restraining orders) in addition to, and not in derogation of, any other remedies provided by law, in equity or otherwise for such a violation, including the right to have such covenants specifically enforced by any court of competent jurisdiction, the rights under Section 14(b), and the right to require the Recipient to account for and pay over to II-VI all benefits derived or received by the Recipient as a result of any such breach of covenant together with interest thereon, from the date of such initial violation until such sums are received by II-VI.

(b) In the event that the Recipient violates or breaches any of the covenants set forth in Section 14, the Performance Units and the right to receive Shares in exchange for such Performance Units shall be forfeited. II-VI shall also have the right, in its sole discretion, in addition to any other remedies or damages provided by law, in equity or otherwise, to demand and require the Recipient (i) to the extent that any cash payment was received with respect to such Performance Units, to return and transfer to II-VI any such cash payment, (ii) to the extent that any Shares were received with respect to such Performance Units, to return and transfer to II-VI any such shares directly or beneficially owned by the Recipient, and (iii) to the extent that the Recipient sold or transferred any such Shares, disgorge and/or repay to II-VI any profits or other economic value (as determined by II-VI) made or realized by the Recipient with respect to such Shares, including the value of any gift thereof.

(c) This Award, and any amounts or benefits received or outstanding under the Plan, as well as any other incentive awards previously granted to the Recipient by the Company, shall be subject to potential clawback, cancellation, recoupment, rescission, payback, reduction, or other similar action in accordance with the terms or conditions of any applicable Company clawback or similar policy or any applicable law related to such actions, as may be in effect from time to time, including the requirements of (a) Section 304 of the Sarbanes Oxley Act and Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, (b) similar rules under the laws of any other jurisdiction, and (c) any policies adopted by the Company to implement such requirements. The Recipient acknowledges and consents to the Company’s application, implementation and enforcement of any applicable Company clawback or similar policy that may apply to the Recipient, whether adopted prior to or

Exhibit 10.20

following the Grant Date, and any provision of applicable law relating to clawback, cancellation, recoupment, rescission, payback, or reduction of compensation, and agrees that the Company may take such actions as may be necessary to effectuate any such policy or applicable law, without further consideration or action.

16.Recipient Acknowledgments. The Recipient acknowledges and agrees that (a) as a result of the Recipient’s previous, current and future employment with the Company or the Employer, the Recipient has had access to, will have access to and/or possesses or will possess confidential and proprietary information of II-VI and its Subsidiaries, (b) II-VI and its Subsidiaries are engaged in a highly competitive business and conduct such business worldwide, (c) this Agreement does not constitute a contract of employment, does not imply that the Company or the Employer will continue the Recipient’s employment for any period of time and does not change the at-will nature of the Recipient’s employment, except as set forth in a separate written employment agreement between the Company or the Employer and the Recipient, (d) the restrictive covenants set forth in Section 14 are necessary and reasonable in time and scope (including the period, geographic, product and service and other restrictions) to protect the legitimate business interests of II-VI and its Subsidiaries, (e) the remedy, forfeiture and payment provisions contained in Section 15 are reasonable and necessary to protect the legitimate business interests of II-VI and its Subsidiaries, (f) acceptance of the Performance Units and agreement to be bound by the provisions hereof is not a condition of the Recipient’s employment and (g) the Recipient’s receipt of the benefits provided under this Agreement is adequate consideration for the enforcement of the provisions contained in Section 14 and Section 15.

17.Severability; Waiver. If any term, provision, covenant or restriction contained in this Agreement is held by a court or a federal regulatory agency of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions contained in this Agreement shall remain in full force and effect, and shall in no way be affected, impaired or invalidated. In particular, in the event that any of such provisions shall be adjudicated to exceed the time, geographic, product and service or other limitations permitted by applicable law in any jurisdiction, then such provisions shall be deemed reformed in such jurisdiction to the maximum time, geographic, product and service or other limitations permitted by applicable law. No delay or omission by II-VI in exercising any right under this Agreement will operate as a waiver of that or any other right. A waiver or consent given by II-VI on any one occasion is effective only in that instance and will not be construed as a bar to or waiver of any right on any other occasion.

18.Notice. II‑VI may require any notice required or permitted under this Agreement to be transmitted, submitted or received, by II‑VI or the Recipient, via the Solium Shareworks System in accordance with the procedures established by II‑VI for such notice. Otherwise, any written notice required or permitted by this Agreement shall be mailed, certified mail (return receipt requested) or by overnight carrier, to II‑VI at the following address:

II‑VI Incorporated Attention: Chief Financial Officer 375 Saxonburg Boulevard Saxonburg, Pennsylvania 16056

or to the Recipient at his or her most recent home address on record with II‑VI. Notices are effective upon receipt.

19.Controlling Law. The validity, construction and effect of this Agreement will be determined in accordance with the internal laws of the Commonwealth of Pennsylvania without giving effect to the conflict of laws principles thereof. The Recipient and II‑VI hereby irrevocably submit to the exclusive jurisdiction of the state and Federal courts located in the Commonwealth of Pennsylvania and consent to the jurisdiction of any such court, provided, however, that, notwithstanding anything to the contrary set forth above, II‑VI may file an action to enforce the covenants contained in Section 14 by seeking injunctive or other equitable relief in any appropriate court having jurisdiction, including where the Recipient resides or where the Recipient was employed by the Company or the Employer. The Recipient and II‑VI also both irrevocably waive, to the fullest extent permitted by applicable law, any objection either may now or hereafter have to the laying of venue of any such dispute brought or injunctive or equitable relief sought in such court or any defense of inconvenient forum for the maintenance of such dispute and consent to the personal jurisdiction

Exhibit 10.20

of any such court. For purposes of this Section 19, the Employer shall be a third-party beneficiary of this Agreement.

20.Entire Agreement. This Agreement (including the Plan and the Employee Grant Details) contains the entire understanding between the parties and supersedes any prior understanding and agreements between them regarding the subject matter hereof with respect to this Award, and there are no other representations, agreements, arrangements or understandings, oral or written, between the parties relating to this Award which are not fully expressed herein. Notwithstanding anything to the contrary set forth in this Agreement, any restrictive covenants contained in this Agreement are independent, and are not intended to limit the enforceability, of any restrictive or other covenants contained in any other agreement between the Company or the Employer and the Recipient.

21.Captions; Section References. Section and other headings contained in this Agreement are for reference purposes only and are in no way intended to describe, interpret, define or limit the scope, extent or intent of this Agreement or any provision hereof. Unless expressly provided otherwise, any reference in this Agreement to any Section refers to the corresponding Section of this Agreement.

22.Limitation of Actions. Any lawsuit commenced by the Recipient with respect to any matter arising out of or relating to this Agreement must be filed no later than one (1) year after the date that a denial of any claim hereunder is made or any earlier date that the claim otherwise accrues.

23.Section 409A. This Agreement and this Award are intended to satisfy all applicable requirements of Section 409A or an exception thereto and shall be construed accordingly. II‑VI may, in its sole discretion and without the consent of the Recipient, take any action it deems necessary to comply with the requirements of Section 409A or an exception thereto, including amending the terms of this Award and this Agreement in any manner it deems necessary to cause this Award and this Agreement to be excepted from Section 409A (or to comply therewith to the extent that II-VI determines it is not excepted). Notwithstanding, the Recipient recognizes and acknowledges that Section 409A may affect the timing and recognition of payments due hereunder, and may impose upon the Recipient certain taxes or other charges for which the Recipient is and shall remain solely responsible.

24.Assignment. Except as provided in Section 7, the Recipient’s rights and obligations under this Agreement shall not be transferable by the Recipient, by assignment or otherwise, and any purported assignment, transfer or delegation thereof by the Recipient shall be void. The Company may assign/delegate all or any portion of this Agreement and its rights hereunder without prior notice to the Recipient and without the Recipient providing any additional consent thereto, whereupon the Recipient shall continue to be bound hereby with respect to such assignee/delegatee.

25.Electronic Delivery. II‑VI may, in its sole discretion, deliver any documents or correspondence related to this Agreement, the Performance Units, the Plan, the Recipient’s participation in the Plan or future awards that may be granted to the Recipient under the Plan, by electronic means. The Recipient hereby consents to receive such documents by electronic delivery and to the Recipient’s participation in the Plan through an on-line or electronic system established and maintained by II‑VI or another third party designated by II‑VI, including the Solium Shareworks System. Likewise, II‑VI may require the Recipient to deliver or receive any documents or correspondence related to this Agreement by such electronic means.

26.Further Assurances. The Company and the Recipient shall use commercially reasonable efforts to, from time to time at the request of the other party, without any additional consideration, furnish the other party such further information or assurances, execute and deliver such additional documents and take such other actions and do such other things, as may be necessary to carry out the provisions of this Agreement.

27.Compliance with Legal Requirements. Notwithstanding any other provisions of the Plan or this Agreement, unless there is an exemption from any registration, qualification or other legal requirement applicable to the Shares, the Company shall not be required to deliver any Shares issuable upon vesting of this Award prior to the completion of any registration or qualification of the Shares under any local, state, federal or foreign securities or exchange control law or under rulings or regulations of the U.S. Securities and Exchange Commission (“SEC”) or of any other governmental regulatory body, or prior to obtaining any approval or other clearance from any local, state, federal or foreign governmental agency, which

Exhibit 10.20

registration, qualification or approval the Company shall, in its absolute discretion, deem necessary or advisable. Further, the Company is under no obligation to register or qualify the Shares with the SEC or any state or foreign securities commission or to seek approval or clearance from any governmental authority for the issuance or sale of Shares. Subject to Section 409A, the Committee may postpone the issuance or delivery of Shares under this Award as the Committee may consider appropriate and may require the Recipient to make such representations and furnish such information as it may consider appropriate in connection with the issuance or delivery of Shares in compliance with applicable laws, rules and regulations. The Recipient understands and agrees that the Company shall have unilateral authority to amend this Agreement without his or her consent to the extent necessary to comply with securities or other laws applicable to the issuance of Shares.

The Recipient understands and agrees that the Recipient should consult with his or her own personal legal and financial advisors regarding the Recipient’s participation in the Plan before taking any action related to the Plan.

31.Amendments. This Agreement may be amended or modified at any time by an instrument in writing signed by the parties hereto, or as otherwise provided under the Plan or this Agreement.

Exhibit 10.20

Appendix A

General Terms Applicable to Awards Granted to Recipients Outside the U.S.

This Appendix A includes additional terms and conditions applicable to all grants of Awards under the Plan to employees or other grant recipients who reside outside the United States. Capitalized terms used but not defined in this Appendix A shall have the meanings given to them in this Agreement or the Plan.

1. DATA PRIVACY INFORMATION AND CONSENT

The Company is located at 375 Saxonburg Blvd., Saxonburg, PA 16056, USA and grants employees of the Company and its Subsidiaries the opportunity to participate in the Plan at the Company’s sole discretion. If the Recipient would like to participate in the Plan, the Recipient should review the following information about the Company’s data processing practices and declare his or her consent.

(a) Data Collection and Usage. The Company collects, processes and uses the Recipient’s personal data, including the Recipient’s name, home address and telephone number, date of birth, social insurance number or other identification number, salary, citizenship, job title, any Shares or directorships held in the Company, and details of all awards canceled, vested, or outstanding in the Recipient’s favor, which the Company receives from the Recipient or the Employer. If the Company offers the Recipient an opportunity to participate in the Plan, then the Company will collect the Recipient’s personal data for purposes of allocating stock and implementing, administering and managing the Plan. The Company’s legal basis for the processing of the Recipient’s personal data would be the Recipient’s consent.

(b) Stock Plan Administration Service Providers. The Company transfers participant data to Solium Capital, an independent service provider based in the United States, which assists the Company with the implementation, administration and management of the Plan. In the future, the Company may select a different service provider and share the Recipient’s data with another company that serves in a similar manner. The Company’s service provider will open an account for the Recipient. The Recipient will be asked to agree on separate terms and data processing practices with the service provider, which is a condition to the Recipient’s ability to participate in the Plan.

(c) International Data Transfers. The Company and its service providers are based in the United States. If the Recipient is outside the United States, the Recipient should note that his or her country has enacted data privacy laws that are different from the United States. For example, the European Commission has issued a limited adequacy finding with respect to the United States that applies only to the extent a company registers for the EU-U.S. Privacy Shield program, which is open to companies subject to Federal Trade Commission jurisdiction, and which the Company does not participate in with respect to employee data. The Company’s legal basis for the transfer of the Recipient’s personal data is the Recipient’s consent.

(d) Data Retention. The Company will use the Recipient’s personal data only as long as is necessary to implement, administer and manage the Recipient’s participation in the Plan or as required to comply with legal or regulatory obligations, including under tax and security laws. When the Company no longer needs the Recipient’s personal data, which will generally be seven years after the Recipient participates in the Plan, the Company will remove it from its systems. If the Company keeps the data longer, it would be to satisfy legal or regulatory obligations and the Company’s legal basis would be relevant laws or regulation.

Exhibit 10.20

(e) Voluntariness and Consequence of Consent Denial or Withdrawal. The Recipient’s participation in the Plan and his or her grant of consent is purely voluntary. The Recipient may deny or withdraw his or her consent at any time. If the Recipient does not consent, or if the Recipient withdraws his or her consent, the Recipient cannot participate in the Plan. This would not affect the Recipient’s salary as an employee; the Recipient would merely forfeit the opportunities associated with the Plan.

(f) Data Subject Rights. The Recipient has a number of rights under data privacy laws in the Recipient’s country. Depending on where the Recipient is based, the Recipient’s rights may include the right to (i) request access or copies of personal data the Company processes, (ii) rectification of incorrect data, (iii) deletion of data, (iv) restrictions on processing, (v) portability of data, (vi) to lodge complaints with competent authorities in the Recipient’s country, and/or (vii) a list with the names and addresses of any potential recipients of the Recipient’s personal data. To receive clarification regarding the Recipient’s rights or to exercise such rights, the Recipient should contact the Company at HR Department, Director of Compensation and Benefits, 375 Saxonburg Blvd., Saxonburg, PA 16056, USA.

If the Recipient agrees with the data processing practices as described in this notice and would like to participate in the Plan, please declare the Recipient’s consent by clicking “Accept” on the Solium Shareworks system award acceptance page or by signing this Agreement.

Exhibit 10.20

(g) unless otherwise agreed with the Company in writing, this Award and any Shares acquired under the Plan, and the income from and value of same, are not granted in consideration for, or in connection with, the service the Recipient may provide as an officer or director of a Subsidiary;

Unless otherwise determined by the Committee, the Recipient’s right to vest in this Award will terminate as of such date and will not be extended by any notice period (e.g., the Recipient’s period of service would not include any contractual notice period or any period of “garden leave” or similar period mandated under labor laws in the jurisdiction where the Recipient is employed or the terms of the Recipient’s employment agreement, if any). The Committee shall have the exclusive discretion to determine when the Recipient is no longer actively providing services for purposes of this Award (including whether the Recipient may still be considered to be providing services while on a leave of absence); and

(l) the Recipient is solely responsible for investigating and complying with any exchange control laws applicable to the Recipient in connection with his or her participation in the Plan;

(m) neither the Company, the Employer nor any Subsidiary shall be liable for any foreign exchange rate fluctuation between the Recipient’s local currency and the United States Dollar that may affect the value of this Award or any amounts due to the Recipient pursuant to the settlement of this Award or subsequent sale of Shares acquired under the Plan.

3. LANGUAGE

The Recipient acknowledges that he or she is sufficiently proficient in English to understand the terms and conditions of this Agreement. Furthermore, if the Recipient has received this Agreement or any other document related to this Award and/or the Plan translated into a language other than English and if the meaning of the translated version is different than the English version , the English version will control.

4. INSIDER TRADING/MARKET ABUSE LAWS

Exhibit 10.20

The Recipient acknowledges that, depending on his or her country of residence, or the designated broker’s country or where the Shares are listed, the Recipient may be subject to insider trading restrictions and/or market abuse laws, which may affect the Recipient’s ability to accept, acquire, sell, attempt to sell or otherwise dispose of Shares or right to Shares (e.g., Awards) or rights linked to the value of Shares during such times as the Recipient is considered to have “inside information” regarding the Company (as defined by or determined under the laws in the applicable jurisdiction). Local insider trading laws and regulations may prohibit the cancellation or amendment of orders placed by the Recipient before possessing inside information. Furthermore, the Recipient could be prohibited from (i) disclosing the inside information to any third party, which may include fellow employees (other than on a “need to know” basis) and (ii) “tipping” third parties or causing them to otherwise buy or sell securities. Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Company insider trading policy. The Recipient is responsible for ensuring compliance with any applicable restrictions and should consult with his or her personal legal advisor on this matter.

5. EXCHANGE CONTROL, TAX AND/OR FOREIGN ASSET/ACCOUNT REPORTING

The Recipient acknowledges that there may be exchange control, tax, foreign asset and/or account reporting requirements which may affect the Recipient’s ability to hold Shares acquired under the Plan or cash received from participating in the Plan in a brokerage/bank account or legal entity outside the Recipient’s country. The Recipient may be required to report such accounts, assets, the balances therein, the value thereof and/or the transactions related thereto to the tax or other authorities in the Recipient’s country. The Recipient may also be required to repatriate sale proceeds or other funds received as a result of participation in the Plan to the Recipient’s country through a designated bank or broker within a certain time after receipt. The Recipient acknowledges that it is his or her responsibility to be compliant with such regulations and that the Recipient should consult with his or her personal legal advisor for any details.

Exhibit 10.20

Appendix B

Jurisdiction-Specific Terms and Conditions

Capitalized terms used but not defined in this Appendix B shall have the meanings given to them in the Agreement or the Plan.

Terms and Conditions

This Appendix B includes additional terms and conditions that govern the Award grants to the Recipient under the Plan if the Recipient works and/or resides in one of the countries or other jurisdictions listed below.

If the Recipient is a citizen or resident of a jurisdiction other than the one in which the Recipient is currently working and/or residing, is considered a resident of another jurisdiction for local law purposes or transfers employment and/or residency between countries or other jurisdictions after the Grant Date, the Company shall, in its sole discretion, determine to what extent the terms and conditions contained herein apply to the Recipient under these circumstances.

Notifications

This Appendix B also includes information regarding country-specific securities laws, exchange controls and certain other issues of which the Recipient should be aware with respect to the Recipient’s participation in the Plan. The information is based on the securities, exchange control and other laws in effect in the respective countries as of May 2018. Such laws are often complex and change frequently. As a result, the Company strongly recommends that the Recipient not rely on the information noted herein as the only source of information relating to the consequences of the Recipient’s participation in the Plan because the information may be out of date at the time this Award vests or the Shares acquired under the Plan are sold.

In addition, the information is general in nature and may not apply to the Recipient’s particular situation, and the Company is not in a position to assure the Recipient of any particular result. Accordingly, the Recipient should seek appropriate professional advice as to how the relevant laws in the Recipient’s country may apply to his or her situation.

Finally, if the Recipient is a citizen or resident of country other than the one in which the Recipient is currently working and/or residing, is considered a resident of another country for local law purposes or transfers employment and/or residence between countries after the Grant Date, the information contained herein may not be applicable in the same manner to the Recipient.

II‑VI Incorporated Performance Share UNIT Award AGREEMENT

(SHARE-SETTLED)

THIS PERFORMANCE SHARE UNIT AWARD AGREEMENT, including any general and jurisdiction-specific terms and conditions for the Recipient’s jurisdiction set forth in the appendices attached hereto, (this “Agreement”) is dated as of the Grant Date, as specified in the applicable Employee Grant Details (as defined below), by and between II-VI Incorporated, a Pennsylvania corporation (“II-VI”), and the Recipient, as specified in the applicable Employee Grant Details, who is a director, employee or consultant of II-VI or one of its Subsidiaries (the “Recipient”).

Reference is made to the Employee Grant Details (the “Employee Grant Details”) issued to the Recipient with respect to the applicable Award, which may be found on the Solium Shareworks system at https://Shareworks.Solium.com (or any successor system selected by II-VI) (the “Solium Shareworks System”). Reference further is made to the prospectus relating to the Plan (as defined below), which also may be found on the Solium Shareworks System.

All capitalized terms used herein, to the extent not defined herein, shall have the meanings set forth in the II-VI 2018 Omnibus Incentive Plan (as amended and/or restated from time to time, the “Plan”), a copy of which can be found on the Solium Shareworks System, and/or the applicable Employee Grant Details. Terms of the Plan and the Employee Grant Details are incorporated herein by reference. This Agreement shall constitute an Award Agreement as that term is defined in the Plan.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, and intending to be legally bound hereby, the Recipient and II-VI agree as follows:

1.Performance Share Unit Award. II-VI hereby grants to the Recipient an Award of Performance Share Units under the Plan, as specified in the Employee Grant Details, to be earned based upon achievement of the Performance Objectives in accordance with Section 2 (this “Award”). For the purposes of this Award: (1) “Performance Period” shall mean the period from July 1, 2019 through and including June 30, 2022;(2) “Target Award” shall mean the Target Award set forth in the Employee Grant Details; (3) “Maximum Award” means the maximum number of Performance Shares that may be earned under this Agreement as set forth in the Employee Grant Details, which number represents 200% of the Target Award; and (4) “Performance Share Unit” or “Unit” means the contingent right to receive the equivalent of one (1) Share, in the event the Unit vests and becomes payable pursuant to the terms of this Agreement. Units shall be payable and settled solely in Shares, except as otherwise provided in this Agreement.

2.Determination of Units Earned. Subject to Section 4 and Section 5, the Units shall be earned in accordance with the following schedule:

Exhibit 10.28

	Units Earned as a Percentage of Target Award
If Cumulative TSR is below Market 50th Percentile by more than 40 percentage points	—%
If Cumulative TSR is equal to 40 percentage points below Market 50th Percentile and there is an absolute positive Cumulative TSR	50.00% (Threshold)
If Cumulative TSR is below Market 50th Percentile by less than 40 percentage points and there is an absolute positive Cumulative TSR	Subtract 1.25% from 100.00% for each1% below Market 50th Percentile
If Cumulative TSR equals Market 50th Percentile	100%
If Cumulative TSR is above Market 50th Percentile by less than 40 percentage points	Add 2.50% to 100.00% for each1% above Market 50th Percentile1
If Cumulative TSR is above Market 50th Percentile by more than 40 percentage points	200.00%1 (Maximum Award)

1 If there is an absolute negative Cumulative TSR for the Performance Period and Cumulative TSR is above Market 50th Percentile, the percentage of the Target Award earned shall be capped at 100.00%.

Definitions:

“Market” is the Russell 2000 as published on July 1, 2019. If a listing is removed from the Russell 2000 during the Performance Period, it will not be replaced, nor will any listing be added for any other reason. The Russell 2000 shall be a closed group for purposes of this Program.

“Cumulative TSR” shall be based on the 30-day average closing stock price of the Shares prior to July 1, 2019 ($34.26) (“Beginning Stock Price”) and the 30-day average closing stock price of the Shares prior to July 1, 2022 (“Ending Stock Price”). Cumulative TSR shall be calculated as follows:

((Ending Stock Price minus Beginning Stock Price ($34.26) plus dividends) divided by Beginning Stock Price ($34.26))

Only whole Units shall be earned in accordance with this Section 2. By way of example and not limitation, earning 66.67% of a Target Award of 100 Units would result in 66 Units being earned and payable.

3.Payment; Dividend Equivalents. The amount determined under Section 2 will be paid to the Recipient in Shares no later than the seventy-fifth (75th) calendar day following the end of the Performance Period. II-VI shall cause a stock certificate (or equivalent electronic book entry) representing Shares equal to the number of Units vested and payable under this Agreement to be issued to the Recipient by such date. In addition, the Recipient shall be entitled to receive, following the completion of the Performance Period but in no event later than March 15th of the calendar year following the completion of the Performance Period, a cash payment equal to the cash dividends that would have been paid during the Performance Period on the applicable number of Shares underlying the Units earned as provided in Section 2 if such Shares had been issued and outstanding during the Performance Period. Such cash dividend equivalents will not vest or be paid prior to the vesting of the Units to which they relate, as specified in this Agreement, and will be subject to cancellation and forfeiture to the same extent that the related Units do not vest or are forfeited. Notwithstanding the foregoing, the Company, at its sole discretion, may settle the Award in cash if necessary or appropriate for legal or administrative reasons based on laws in the Recipient’s jurisdiction, in which case the Company shall pay to the Recipient an amount in cash equal to the product of (a) the number of Units earned in accordance with Section 2 and (b) the Fair Market Value on the day prior to the Committee’s approval of the number of Units earned following completion of the Performance Period, with

Exhibit 10.28

such cash payment being made to the Recipient no later than the seventy fifth (75th) calendar day following the end of the Performance Period.

4. Separation from Service.

(a) General. Except as provided in Section 4(b) or Section 5 or as may be otherwise determined by the Committee, if the Recipient’s Separation from Service occurs before the end of the Performance Period, this Award shall be forfeited on the date of such Separation from Service.

(b) Prorating in Certain Circumstances. Notwithstanding Section 4(a), if the Recipient’s Separation from Service occurs during the Performance Period due to the Recipient’s (i) normal retirement, as defined in II-VI’s Global Retirement Policy, (ii) death, (iii) permanent and total disability, as defined in Code Section 22(e)(3) (a “Disability”), (iv) termination by the Company or a Subsidiary that the Recipient is employed by or provides services to (the “Employer”) other than for Cause (as defined below) other than within two years following a Change in Control or (v) termination by the Recipient for Good Reason (as defined below) other than within two years following a Change in Control, but only if the Recipient’s offer letter, employment agreement or other applicable employment or service agreement with the Company or the Employer provides for severance upon Separation from Service for Good Reason (or similar term), then in each case under clauses (i) - (v) of this paragraph the Recipient shall be entitled to a prorated portion of the Units to the extent earned pursuant to Section 2, determined at the end of the Performance Period and based on the ratio of the number of complete months the Recipient was employed or served (as applicable) during the Performance Period to the total number of months in the Performance Period. In the event of the death of the Recipient, delivery of the applicable number of Shares shall be made to the Recipient’s estate as soon as administratively practicable after the end of the Performance Period. Notwithstanding any provision of this Agreement, if the Company receives a legal opinion that, due to a legal judgment and/or development in the Recipient’s jurisdiction, the potential pro-rated vesting that applies to this Award upon a Recipient’s normal retirement would be deemed unlawful or discriminatory, the provisions of this Section 4(b)(i) regarding the vesting of this Award if the Recipient’s Separation from Service is as a result of normal retirement will not be applicable to the Recipient and the remaining provisions of this Agreement will govern.

5. Change in Control; Adjustments to Payments.

(a) Change in Control. Upon a Change in Control, the Award shall be subject to Section 10 of the Plan, with “Cause” and “Good Reason” for such purpose as defined below.

(b) “Cause” shall be defined as that term is defined in the Recipient’s offer letter, employment agreement or other applicable employment or service agreement with the Company; or, if there is no such definition, “Cause” shall mean a determination by the Company that any of the following has occurred:

(i) the willful failure by the Recipient to perform the Recipient’s duties and responsibilities to the Company or the Employer (other than any such failure resulting from the Recipient’s Disability), which is not cured within ten (10) business days of receiving written notice from the Company or the Employer specifying in reasonable detail the duties or responsibilities that the Company or the Employer believes are not being adequately performed;

(ii) the willful engaging by the Recipient in any act that is damaging to the Company or the Employer;

(iii) the conviction of the Recipient of, or a plea of “guilty” or “no contest” to, (A) any felony or (B) a criminal offense involving fraud, dishonesty or other moral turpitude;

(iv) any breach by the Recipient of the terms of any written agreement between the Recipient and the Company relating to proprietary information, confidentiality, non-disclosure, ownership of inventions, non-competition, non-solicitation, non-interference or non-disparagement;

(v) the engaging by the Recipient in any willful act of dishonesty resulting or intended to result, directly or indirectly, in personal gain to the Recipient; or

(vi) the commission of any act by the Recipient that is in violation of the Company’s Code of Business Conduct and Ethics.

Exhibit 10.28

(c) “Good Reason” shall be defined as that term is defined in the Recipient’s offer letter, employment agreement or other applicable employment or service agreement with the Company; or, if there is no such definition, “Good Reason” shall mean that any of the following has occurred, without the Recipient’s express written consent:

(i) a material reduction of the Recipient’s employment responsibilities from those immediately prior to the Change in Control;

(ii) a material reduction by the Company or the Employer of the Recipient’s eligibility for Total Target Compensation as in effect immediately prior to the Change in Control, with “Total Target Compensation” defined as the Recipient’s annual base salary plus the cash and stock compensation the Recipient is eligible to receive from the Company or the Employer at one hundred percent (100%) performance, whether sales incentive, bonus or otherwise;

(iii) a material increase in the amount of the Recipient’s business travel that produces a constructive relocation of the Recipient;

(iv) a material reduction by the Company or the Employer in the kind or level of employee benefits to which the Recipient is entitled immediately prior to the Change in Control, with the result that the Recipient’s overall benefits package is materially reduced; or

(v) the relocation of the Recipient to a facility or a location more than thirty (30) miles from the Recipient’s principal place of employment immediately prior to the Change in Control.

In order for the Recipient to incur a Separation from Service for Good Reason, (A) the Company must be notified by the Recipient in writing within ninety (90) days of the event constituting Good Reason, (B) the event must remain uncorrected by the Company or the Employer (as applicable) for thirty (30) days following such notice (the “Notice Period”), and (C) such Separation from Service must occur within sixty (60) days after the expiration of the Notice Period.

(d) Adjustments to Payments.

(i) Notwithstanding any provision to the contrary in this Agreement, if it is determined that any payment or distribution by the Company or the Employer to the Recipient or for the Recipient’s benefit (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise) (the “Payments”) would be subject to the excise tax imposed by Code Section 4999, or any interest or penalty is incurred by the Recipient with respect to such excise tax (such excise tax, together with any such interest and penalties, collectively referred to as the “Excise Tax”), then the Payments shall be reduced (but not below zero) if and to the extent that such reduction would result in the Recipient retaining a larger amount, on an after-tax basis (taking into account federal, state and local income taxes and the imposition of the Excise Tax), than if the Recipient received all of the Payments. The Company shall reduce or eliminate the Payments by first reducing or eliminating the portion of the Payments that are not payable in cash and then by reducing or eliminating cash payments, in each case in reverse order beginning with payments or benefits that are to be paid the farthest in time from the determination.

(ii) All determinations required to be made under this Section 5(d), including whether and when an adjustment to any Payments is required and, if applicable, which Payments are to be so adjusted, shall be made by an independent accounting firm selected by II-VI from among the four (4) largest accounting firms in the United States or any nationally-recognized financial planning and benefits consulting company (the “Accounting Firm”), which shall provide detailed supporting calculations both to II-VI and to the Recipient within fifteen (15) business days of the receipt of notice from the Recipient that there has been a Payment, or such earlier time as is requested by II-VI. In the event that the Accounting Firm is serving as accountant or auditor for the individual, entity or group effecting the Change in Control, II-VI shall appoint another nationally-recognized accounting firm to make the determinations required hereunder (which accounting firm shall then be referred to as the Accounting Firm hereunder). All fees and expenses of the Accounting Firm shall be borne solely by II-VI. If the Accounting Firm determines that no Excise Tax is payable by the Recipient, it shall furnish the Recipient with a written opinion that failure to report the Excise Tax on the Recipient’s applicable federal income

Exhibit 10.28

tax return would not result in the imposition of a negligence or similar penalty. Any determination by the Accounting Firm shall be binding upon the Company and the Recipient.

6. Nontransferability. Except as otherwise provided in the Plan, the Units shall not be sold, pledged, assigned, hypothecated, transferred or disposed of (a “Transfer”) in any manner, other than by will or the laws of descent and distribution. Any attempt to Transfer the Units in violation of this Section or the Plan shall render this Award null and void.

7. Adjustments. Upon any event described in Section 12 of the Plan (entitled “Adjustments”) or any successor provision thereto, the terms of such Section 12 of the Plan or any successor provision thereto shall apply to this Award.

8. Fractional Shares. II-VI shall not be required to issue any fractional Shares pursuant to this Award, and II-VI may round fractional Shares down to the nearest whole Share.

9. Responsibility for Taxes.

i.Regardless of any action the Company or the Employer takes with respect to any or all income tax, social insurance, payroll tax, fringe benefit tax, payment on account or other tax-related items related to the Recipient’s participation in the Plan (“Tax-Related Items”), the Recipient acknowledges that the ultimate liability for all Tax-Related Items owed by the Recipient is and remains the Recipient’s responsibility and that the Company (i) makes no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of this Award, including the grant or vesting of this Award or the subsequent sale of Shares acquired pursuant to this Award; and (ii) does not commit to structure the terms of the grant or any aspect of this Award to reduce or eliminate the Recipient’s liability for Tax-Related Items or achieve a particular tax result. Further, if the Recipient is subject to Tax-Related Items in more than one jurisdiction, the Recipient acknowledges and agrees that the Company or the Employer may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

ii.Prior to any relevant taxable or tax withholding event, as applicable the Recipient agrees to make adequate arrangements satisfactory to the Company to satisfy all Tax-Related Items. In this regard, the Recipient authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy any applicable withholding obligations with regard to Tax-Related Items by one or a combination of the following: (i) withholding from the Recipient’s wages or other cash compensation paid to the Recipient by the Company or the Employer; (ii) withholding from the proceeds of the sale of Shares acquired upon vesting of this Award either through a voluntary sale or through a mandatory sale arranged by the Company (on the Recipient’s behalf pursuant to this authorization) without further consent; (iii) withholding Shares to be issued upon vesting of this Award; or (iv) any other method determined by the Committee and permitted by applicable laws. Notwithstanding the foregoing, if the Recipient is subject to the short-swing profit rules of Section 16(b) of the Exchange Act, the Company will withhold in Shares issuable at vesting of the Award upon the relevant withholding event, unless otherwise determined by the Committee.

iii.The Company may withhold or account for Tax-Related Items by considering applicable withholding rates, including maximum applicable rates, in which case the Recipient may receive a refund of any over-withheld amount in cash (with no entitlement to the equivalent in Shares), or, if not refunded, the Recipient may seek a refund from the local tax authorities. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, the Recipient is deemed to have been issued the full number of Shares, notwithstanding that a number of Shares are held back solely for the purpose of paying the Tax-Related Items.

iv.Finally, the Recipient shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of the Recipient’s participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to issue or deliver Shares or the proceeds from the sale of Shares, if the

Exhibit 10.28

Recipient fails to comply with the Recipient’s obligations in connection with the Tax-Related Items, as described in this Section 9.

10. Plan Provisions. In the event of any conflict between the provisions of this Agreement and the Plan, the Plan shall control, except that capitalized terms specifically defined in this Agreement shall have the meaning given to them in this Agreement with respect to their usage in this Agreement, notwithstanding the definitions given to such terms in the Plan (which definitions shall control as they relate to the usage of such terms in the Plan).

11. No Continued Rights. The granting of this Award shall not give the Recipient any rights to similar grants in future years or any right to continuance of employment or other service with II-VI or its Subsidiaries, nor shall it interfere in any way with any right that the Company or the Employer would otherwise have to terminate the Recipient’s employment or other services at any time, or the right of the Recipient to terminate his or her employment or other service at any time.

12. Rights Unsecured. The Recipient shall have only II-VI’s unfunded, unsecured promise to pay pursuant to the terms of this Agreement. The rights of the Recipient hereunder shall be that of a general unsecured creditor of II-VI and the Recipient shall not have any security interest in any assets of II-VI.

13. Non-Competition; Non-Solicitation; Confidentiality.

(a) While the Recipient is employed by the Company (including its Subsidiaries) and for a period of one (1) year after the Recipient’s Separation from Service for any reason (the “Restricted Period”), the Recipient will not directly or indirectly:

(i) engage in any business or enterprise (whether as owner, partner, officer, director, employee, consultant, investor, lender or otherwise, except as the holder of not more than one percent (1%) of the outstanding stock of a publicly-held company), that develops, manufactures, markets or sells any product or service that competes with any product or service developed, manufactured, marketed or sold or, to the Recipient’s knowledge, planned to be developed, manufactured, marketed or sold, by II-VI or its Subsidiaries while the Recipient was employed by the Company or a Subsidiary, within the United States of America, and/or any other country within which II-VI or its Subsidiaries have customers or prospective customers as of the date of such Separation from Service;

(ii) (A) solicit for the purpose of selling or distributing any products or services that are the same or similar to those developed, manufactured, marketed or sold by II-VI or its Subsidiaries, (1) any customers of II-VI or its Subsidiaries, (2) any prospective customers known by the Recipient to have been solicited by II-VI or its Subsidiaries within the twelve (12) months prior to the Recipient’s Separation from Service, or (3) any distributors, sales agents or other third-parties who sell to or refer potential customers in need of the types of products and services produced, marketed, licensed, sold or provided by II-VI or its Subsidiaries who have become known to the Recipient as a result of his/her employment with the Company (including its Subsidiaries), or (B) induce or attempt to induce any vendor, supplier, licensee or other business relation of II-VI or its Subsidiaries to cease or restrict doing business with II-VI or its Subsidiaries, or in any way interfere with the relationship between any such vendor, supplier, licensee or business relation and II-VI or its Subsidiaries; or

(iii) either alone or in association with others (A) solicit, or permit any organization directly or indirectly controlled by the Recipient to solicit, any employee of II-VI or its Subsidiaries to leave the employ of II-VI or its Subsidiaries, or (B) solicit for employment, hire or engage as an independent contractor, or permit any organization directly or indirectly controlled by the Recipient to solicit for employment, hire or engage as an independent contractor, any person who was employed by II-VI or its Subsidiaries at any time during the term of the Recipient’s employment with the Company or a Subsidiary; provided that this clause (B) shall not apply to any individual whose employment with II-VI or its Subsidiaries has been terminated for a period of one (1) year or longer.

(b) The Recipient acknowledges that certain materials, including information, data, technology and other materials relating to customers, programs, costs, marketing, investment, sales activities, promotion, credit and financial data, manufacturing processes, financing methods, plans or the business and affairs of II-VI and its Subsidiaries constitute proprietary confidential information and trade secrets. Accordingly, the Recipient will not at any time during or after the Recipient’s employment with the Company or a Subsidiary disclose or use for the Recipient’s own benefit or purposes or the benefit or purposes of any other person, firm, partnership, joint venture, association, corporation or other business organization, entity or enterprise, other than the Company (including its Subsidiaries), any proprietary confidential information or trade secrets; provided that the foregoing shall not apply to information which is not unique to II-VI and its Subsidiaries or which is generally known to the industry or the public other than as a result of the Recipient’s breach of this covenant. The Recipient agrees that, upon the Recipient’s Separation from Service for any reason, the Recipient will immediately return to II-VI all property of II-VI and its Subsidiaries, including all memoranda, books, technical and/or lab notebooks, customer product and pricing data, papers, plans, information, letters and other data, and all copies thereof or therefrom, which in any way relate to the business of II-VI and its Subsidiaries, except that the Recipient may retain personal items. The Recipient further agrees that the Recipient will not retain or use for the Recipient’s account at any time any trade names, trademark or other proprietary business designation used or owned in connection with the business of II-VI and its Subsidiaries.

(c) The Restricted Period will be tolled during and for any period of time during which the Recipient is in violation of the restrictive covenants contained in this Section 13 and for any period of time which may be necessary to secure an order of court or injunction, either preliminary or permanent, to enforce such covenants, such that the cumulative time period during which the Recipient is in compliance with the restrictive covenants contained in Section 13 will not exceed the one (1)-year period set forth above.

(d) Nothing herein is intended to or shall limit, prevent, impede or interfere with the Recipient’s non-waivable right, without prior notice to the Company, to provide information to the government, participate in investigations, testify in proceedings regarding the Company’s past or future conduct, or engage in any activities protected under whistleblower statutes, or to receive and fully retain a monetary award from a government-administered whistleblower award program for providing information directly to a government agency. Further, the Recipient understands that pursuant to the Defend Trade Secrets Act of 2016, the Recipient shall not be held criminally, or civilly, liable under any Federal or State Trade secret law for the disclosure of a trade secret that is made in confidence either directly or indirectly to a Federal, State, or local government official, or an attorney, for the sole purpose of reporting, or investigating, a violation of law. Moreover, the Recipient understands that he or she may disclose trade secrets in a complaint, or other document, filed in a lawsuit, or other proceeding, if such filing is made under seal. Finally, the Recipient understands that if he or she files a lawsuit alleging retaliation by the Company for reporting a suspected violation of the law, the Recipient may disclose the trade secret to the attorney and use the trade secret in the court proceeding.

14. Remedies; Clawback.

(a) II-VI and the Recipient acknowledge and agree that that any violation by the Recipient of any of the restrictive covenants contained in Section 13 would cause immediate, material and irreparable harm to the II-VI and its Subsidiaries which may not adequately be compensated by money damages and, therefore, II-VI and its Subsidiaries shall be entitled to injunctive relief (including one (1) or more preliminary injunctions and/or ex parte restraining orders) in addition to, and not in derogation of, any other remedies provided by law, in equity or otherwise for such a violation, including the right to have such covenants specifically enforced by any court of competent jurisdiction, the rights under Section 14(b), and the right to require the Recipient to account for and pay

Exhibit 10.28

over to II-VI all benefits derived or received by the Recipient as a result of any such breach of covenant together with interest thereon, from the date of such initial violation until such sums are received by II-VI.

(b) In the event that the Recipient violates or breaches any of the covenants set forth in Section 13, the Units and the right to receive Shares in exchange for such Units shall be forfeited. II-VI shall also have the right, in its sole discretion, in addition to any other remedies or damages provided by law, in equity or otherwise, to demand and require the Recipient (i) to the extent that any cash payment was received with respect to such Performance Units, to return and transfer to II-VI any such cash payment, (ii) to the extent that any Shares were received with respect to such Units, to return and transfer to II-VI any such shares directly or beneficially owned by the Recipient, and (iii) to the extent that the Recipient sold or transferred any such Shares, to disgorge and/or repay to II-VI any profits or other economic value (as determined by II-VI) made or realized by the Recipient with respect to such shares, including the value of any gift thereof.

(c) This Award, and any amounts or benefits received or outstanding under the Plan, as well as any other incentive awards previously granted to the Recipient by the Company, shall be subject to potential clawback, cancellation, recoupment, rescission, payback, reduction, or other similar action in accordance with the terms or conditions of any applicable Company clawback or similar policy or any applicable law related to such actions, as may be in effect from time to time, including the requirements of (a) Section 304 of the Sarbanes Oxley Act and Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, (b) similar rules under the laws of any other jurisdiction, and (c) any policies adopted by the Company to implement such requirements. The Recipient acknowledges and consents to the Company’s application, implementation and enforcement of any applicable Company clawback or similar policy that may apply to the Recipient, whether adopted prior to or following the Grant Date, and any provision of applicable law relating to clawback, cancellation, recoupment, rescission, payback, or reduction of compensation, and agrees that the Company may take such actions as may be necessary to effectuate any such policy or applicable law, without further consideration or action.

15. Recipient Acknowledgments. The Recipient acknowledges and agrees that (a) as a result of the Recipient’s previous, current and future employment with the Company or the Employer, the Recipient has had access to, will have access to and/or possesses or will possess confidential and proprietary information of II-VI and its Subsidiaries, (b) II-VI and its Subsidiaries are engaged in a highly competitive business and conduct such business worldwide, (c) this Agreement does not constitute a contract of employment, does not imply that the Company or the Employer will continue the Recipient’s employment for any period of time and does not change the at-will nature of the Recipient’s employment, except as set forth in a separate written employment agreement between the Company or the Employer and the Recipient, (d) the restrictive covenants set forth in Section 13 are necessary and reasonable in time and scope (including the period, geographic, product and service and other restrictions) to protect the legitimate business interests of II-VI and its Subsidiaries, (e) the remedy, forfeiture and payment provisions contained in Section 14 are reasonable and necessary to protect the legitimate business interests of II-VI and its Subsidiaries, (f) acceptance of these Units and agreement to be bound by the provisions hereof is not a condition of the Recipient’s employment and (g) the Recipient’s receipt of the benefits provided under this Agreement is adequate consideration for the enforcement of the provisions contained in Section 13 and Section 14.

16. Severability; Waiver. If any term, provision, covenant or restriction contained in this Agreement is held by a court or a federal regulatory agency of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions contained in this Agreement shall remain in full force and effect, and shall in no way be affected, impaired or invalidated. In particular, in the event that any of such provisions shall be adjudicated to exceed the time, geographic, product and service or other limitations permitted by applicable law in any jurisdiction, then such provisions shall be deemed reformed in such jurisdiction to the maximum time, geographic, product and service or other limitations permitted by applicable law. No delay or omission by II-VI in exercising any right under this Agreement will operate as a waiver of that or any other right. A waiver or consent given by II-VI on any one occasion is effective only in that instance and will not be construed as a bar to or waiver of any right on any other occasion.

Exhibit 10.28

17. Notice. II-VI may require any notice required or permitted under this Agreement to be transmitted, submitted or received, by II-VI or the Recipient, via the StockPlan Connect System in accordance with the procedures established by II-VI for such notice.

18. Controlling Law. The validity, construction and effect of this Agreement will be determined in accordance with the internal laws of the Commonwealth of Pennsylvania without giving effect to the conflict of laws principles thereof. The Recipient and II-VI hereby irrevocably submit to the exclusive jurisdiction of the state and Federal courts located in the Commonwealth of Pennsylvania and consent to the jurisdiction of any such court, provided, however, that, notwithstanding anything to the contrary set forth above, II-VI may file an action to enforce the covenants contained in Section 13 by seeking injunctive or other equitable relief in any appropriate court having jurisdiction, including where the Recipient resides or where the Recipient was employed by the Company or the Employer. The Recipient and II-VI also both irrevocably waive, to the fullest extent permitted by applicable law, any objection either may now or hereafter have to the laying of venue of any such dispute brought or injunctive or equitable relief sought in such court or any defense of inconvenient forum for the maintenance of such dispute and consent to the personal jurisdiction of any such court. For purposes of this Section 18, the Employer shall be a third-party beneficiary of this Agreement.

19. Entire Agreement. This Agreement (including the Plan and the Employee Grant Details) contains the entire understanding between the parties and supersedes any prior understanding and agreements between them regarding the subject matter hereof with respect to this Award, and there are no other representations, agreements, arrangements or understandings, oral or written, between the parties relating to this Award which are not fully expressed herein. Notwithstanding anything to the contrary set forth in this Agreement, any restrictive covenants contained in this Agreement are independent, and are not intended to limit the enforceability, of any restrictive or other covenants contained in any other agreement between the Company or the Employer and the Recipient.

20. Captions; Section References. Section and other headings contained in this Agreement are for reference purposes only and are in no way intended to describe, interpret, define or limit the scope, extent or intent of this Agreement or any provision hereof. Unless expressly provided otherwise, any reference in this Agreement to any Section refers to the corresponding Section of this Agreement.

21. Limitation of Actions. Any lawsuit commenced by the Recipient with respect to any matter arising out of or relating to this Agreement must be filed no later than one (1) year after the date that a denial of any claim hereunder is made or any earlier date that the claim otherwise accrues.

22. Section 409A. This Agreement and this Award are intended to satisfy all applicable requirements of Section 409A or an exception thereto and shall be construed accordingly. II-VI may in its sole discretion, and without the consent of the Recipient, take any action it deems necessary to comply with the requirements of Section 409A or an exception thereto, including amending the terms of this Award and this Agreement, in any manner it deems necessary to cause this Award and this Agreement to be excepted from Section 409A (or to comply therewith to the extent that II-VI determines that it is not excepted). Notwithstanding, the Recipient recognizes and acknowledges that Section 409A may affect the timing and recognition of payments due hereunder, and may impose upon the Recipient certain taxes or other charges for which the Recipient is and shall remain solely responsible.

Exhibit 10.28

23. Assignment. Except as provided in Section 6, the Recipient’s rights and obligations under this Agreement shall not be transferable by the Recipient, by assignment or otherwise, and any purported assignment, transfer or delegation thereof by the Recipient shall be void. II-VI and the Company may assign/delegate all or any portion of this Agreement and its rights hereunder without prior notice to the Recipient and without the Recipient providing any additional consent thereto, whereupon the Recipient shall continue to be bound hereby with respect to such assignee/delegatee.

24. Electronic Delivery. II-VI may, in its sole discretion, deliver any documents or correspondence related to this Agreement, the Units, the Plan, the Recipient’s participation in the Plan or future awards that may be granted to the Recipient under the Plan, by electronic means. The Recipient hereby consents to receive such documents by electronic delivery and to the Recipient’s participation in the Plan through an on-line or electronic system established and maintained by II-VI or another third party designated by II-VI, including the Solium Shareworks System. Likewise, II-VI may require the Recipient to deliver or receive any documents or correspondence related to this Agreement by such electronic means.

25. Further Assurances. The Company and the Recipient shall use commercially reasonable efforts to, from time to time at the request of the other party, without any additional consideration, furnish the other party such further information or assurances, execute and deliver such additional documents and take such other actions and do such other things, as may be necessary to carry out the provisions of this Agreement.

26. Compliance with Legal Requirements. Notwithstanding any other provisions of the Plan or this Agreement, unless there is an exemption from any registration, qualification or other legal requirement applicable to the Shares, the Company shall not be required to deliver any Shares issuable upon vesting of this Award prior to the completion of any registration or qualification of the Shares under any local, state, federal or foreign securities or exchange control law or under rulings or regulations of the U.S. Securities and Exchange Commission (“SEC”) or of any other governmental regulatory body, or prior to obtaining any approval or other clearance from any local, state, federal or foreign governmental agency, which registration, qualification or approval the Company shall, in its absolute discretion, deem necessary or advisable. Further, the Company is under no obligation to register or qualify the Shares with the SEC or any state or foreign securities commission or to seek approval or clearance from any governmental authority for the issuance or sale of Shares. Subject to Section 409A, the Committee may postpone the issuance or delivery of Shares under this Award as the Committee may consider appropriate and may require the Recipient to make such representations and furnish such information as it may consider appropriate in connection with the issuance or delivery of Shares in compliance with applicable laws, rules and regulations.

The Recipient understands and agrees that the Recipient should consult with his or her own personal legal and financial advisors regarding the Recipient’s participation in the Plan before taking any action related to the Plan.

Exhibit 10.28

Appendix A

General Terms Applicable to Awards Granted to Recipients Outside the U.S.

This Appendix A includes additional terms and conditions applicable to all grants of Awards under the Plan to employees or other grant recipients who reside outside the United States. Capitalized terms used but not defined in this Appendix A shall have the meanings given to them in this Agreement or the Plan.

1. DATA PRIVACY INFORMATION AND CONSENT

The Company is located at 375 Saxonburg Blvd., Saxonburg, PA 16056, USA and grants employees of the Company and its Subsidiaries the opportunity to participate in the Plan at the Company’s sole discretion. If the Recipient would like to participate in the Plan, the Recipient should review the following information about the Company’s data processing practices and declare his or her consent.

i.Data Collection and Usage. The Company collects, processes and uses the Recipient’s personal data, including the Recipient’s name, home address and telephone number, date of birth, social insurance number or other identification number, salary, citizenship, job title, any Shares or directorships held in the Company, and details of all awards canceled, vested, or outstanding in the Recipient’s favor, which the Company receives from the Recipient or the Employer. If the Company offers the Recipient an opportunity to participate in the Plan, then the Company will collect the Recipient’s personal data for purposes of allocating stock and implementing, administering and managing the Plan. The Company’s legal basis for the processing of the Recipient’s personal data would be the Recipient’s consent.

ii.Stock Plan Administration Service Providers. The Company transfers participant data to Solium Capital, an independent service provider based in the United States, which assists the Company with the implementation, administration and management of the Plan. In the future, the Company may select a different service provider and share the Recipient’s data with another company that serves in a similar manner. The Company’s service provider will open an account for the Recipient. The Recipient will be asked to agree on separate terms and data processing practices with the service provider, which is a condition to the Recipient’s ability to participate in the Plan.

iii.International Data Transfers. The Company and its service providers are based in the United States. If the Recipient is outside the United States, the Recipient should note that his or her country has enacted data privacy laws that are different from the United States. For example, the European Commission has issued a limited adequacy finding with respect to the United States that applies only to the extent a company registers for the EU-U.S. Privacy Shield program, which is open to companies subject to Federal Trade Commission jurisdiction, and which the Company does not participate in with respect to employee data. The Company’s legal basis for the transfer of the Recipient’s personal data is the Recipient’s consent.

iv.Data Retention. The Company will use the Recipient’s personal data only as long as is necessary to implement, administer and manage the Recipient’s participation in the Plan or as required to comply with legal or regulatory obligations, including under tax and security laws. When the Company no longer needs the Recipient’s personal data, which will generally be seven years after the Recipient participates in the Plan, the Company will remove it from its systems. If the Company keeps the data longer, it would be to satisfy legal or regulatory obligations and the Company’s legal basis would be relevant laws or regulation.

v.Voluntariness and Consequence of Consent Denial or Withdrawal. The Recipient’s participation in the Plan and his or her grant of consent is purely voluntary. The Recipient may deny or withdraw his or her consent at any time. If the Recipient does not consent, or if the Recipient withdraws his or her consent, the Recipient cannot participate in the Plan. This would not affect the Recipient’s salary as an employee; the Recipient would merely forfeit the opportunities associated with the Plan.

Exhibit 10.28

vi.Data Subject Rights. The Recipient has a number of rights under data privacy laws in the Recipient’s country. Depending on where the Recipient is based, the Recipient’s rights may include the right to (i) request access or copies of personal data the Company processes, (ii) rectification of incorrect data, (iii) deletion of data, (iv) restrictions on processing, (v) portability of data, (vi) to lodge complaints with competent authorities in the Recipient’s country, and/or (vii) a list with the names and addresses of any potential recipients of the Recipient’s personal data. To receive clarification regarding the Recipient’s rights or to exercise such rights, the Recipient should contact the Company at HR Department, Director of Compensation and Benefits, 375 Saxonburg Blvd., Saxonburg, PA 16056, USA.

If the Recipient agrees with the data processing practices as described in this notice and would like to participate in the Plan, please declare the Recipient’s consent by clicking “Accept” on the Solium Shareworks system award acceptance page or by signing this Agreement.

Exhibit 10.28

employment agreement, if any).

b. LANGUAGE

The Recipient acknowledges that he or she is sufficiently proficient in English to understand the terms and conditions of this Agreement. Furthermore, if the Recipient has received this Agreement or any other document related to this Award and/or the Plan translated into a language other than English and if the meaning of the translated version is different than the English version, the English version will control.

a. INSIDER TRADING/MARKET ABUSE LAWS

The Recipient acknowledges that, depending on his or her country of residence, or the designated broker’s country or where the Shares are listed, the Recipient may be subject to insider trading restrictions and/or market abuse laws, which may affect the Recipient’s ability to accept, acquire, sell, attempt to sell or otherwise dispose of Shares or right to Shares (e.g., Awards) or rights linked to the value of Shares during such times as the Recipient is considered to have “inside information” regarding the Company (as defined by or determined under the laws in the applicable jurisdiction). Local insider trading laws and regulations may prohibit the cancellation or amendment of orders placed by the Recipient before possessing inside information. Furthermore, the Recipient could be prohibited from (i) disclosing the inside information to any third party, which may include fellow employees (other than on a “need to know” basis) and (ii) “tipping” third parties or causing them to otherwise buy or sell securities. Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Company insider trading policy. The Recipient is responsible for ensuring compliance with any applicable restrictions and should consult with his or her personal legal advisor on this matter.

a. EXCHANGE CONTROL, TAX AND/OR FOREIGN ASSET/ACCOUNT REPORTING

The Recipient acknowledges that there may be exchange control, tax, foreign asset and/or account reporting requirements which may affect the Recipient’s ability to hold Shares acquired under the Plan or cash received from participating in the Plan in a brokerage/bank account or legal entity outside the Recipient’s country. The Recipient may be required to report such accounts, assets, the balances therein, the value thereof and/or the transactions related thereto to the tax or other authorities in the Recipient’s country. The Recipient may also be required to repatriate sale proceeds or other funds received as a result of participation in the Plan to the Recipient’s country through a designated bank or broker within a certain time after receipt. The Recipient acknowledges that it is his or her responsibility to be compliant with such regulations and that the Recipient should consult with his or her personal legal advisor for any details.

Exhibit 10.28

Appendix B

Jurisdiction-Specific Terms and Conditions

Capitalized terms used but not defined in this Appendix B shall have the meanings given to them in the Agreement or the Plan.

Terms and Conditions

This Appendix B includes additional terms and conditions that govern the Award grants to the Recipient under the Plan if the Recipient works and/or resides in one of the countries or other jurisdictions listed below.

If the Recipient is a citizen or resident of a jurisdiction other than the one in which the Recipient is currently working and/or residing, is considered a resident of another jurisdiction for local law purposes or transfers employment and/or residency between countries or other jurisdictions after the Grant Date, the Company shall, in its sole discretion, determine to what extent the terms and conditions contained herein apply to the Recipient under these circumstances.

Notifications

This Appendix B also includes information regarding country-specific securities laws, exchange controls and certain other issues of which the Recipient should be aware with respect to the Recipient’s participation in the Plan. The information is based on the securities, exchange control and other laws in effect in the respective countries as of May 2018. Such laws are often complex and change frequently. As a result, the Company strongly recommends that the Recipient not rely on the information noted herein as the only source of information relating to the consequences of the Recipient’s participation in the Plan because the information may be out of date at the time this Award vests or the Shares acquired under the Plan are sold.

In addition, the information is general in nature and may not apply to the Recipient’s particular situation, and the Company is not in a position to assure the Recipient of any particular result. Accordingly, the Recipient should seek appropriate professional advice as to how the relevant laws in the Recipient’s country may apply to his or her situation.

Finally, if the Recipient is a citizen or resident of country other than the one in which the Recipient is currently working and/or residing, is considered a resident of another country for local law purposes or transfers employment and/or residence between countries after the Grant Date, the information contained herein may not be applicable in the same manner to the Recipient.

Responsibility for Taxes. The following provision supplements Section 9 of the Agreement.

Without limitation to Section 9 of the Agreement, the Recipient agrees that he or she is liable for all Tax-Related Items and hereby covenants to pay all such Tax-Related Items, as and when requested by the Company or the Employer or by Her Majesty’s Revenue and Customs (“HMRC”) (or any other tax authority or any other relevant authority). The Recipient also agrees to indemnify and keep indemnified the Company and the Employer against any Tax-Related Items that they are required to pay or withhold or have paid or will pay to HMRC on the Recipient’s behalf (or any other tax authority or other relevant authority).

In this case, the Tax-Related Items not collected or paid may constitute a benefit to the Recipient on which additional income tax and National Insurance Contributions (“NICs”) may be payable. The Recipient understands that he or she will be responsible for reporting and paying any income tax due on this additional benefit directly to HMRC under the self-assessment regime and for paying to the Company and/or the Employer (as appropriate) the amount of any NICs due on this additional benefit, which may also be recovered from the Recipient by any of the means referred to in Section 9 of the Agreement.

II-VI INCORPORATED

PERFORMANCE SHARE UNIT AWARD AGREEMENT

(CASH FLOW; SHARE-SETTLED)

THIS PERFORMANCE SHARE UNIT AWARD AGREEMENT, including any general and jurisdiction-specific terms and conditions for the Recipient’s jurisdiction set forth in the appendices attached hereto, (this “Agreement”) is dated as of the Grant Date, as specified in the applicable Employee Grant Details

(as defined below), by and between II-VI Incorporated, a Pennsylvania corporation (“II-VI”), and the Recipient, as specified in the applicable Employee Grant Details, who is a director, employee or consultant of II-VI or one of its Subsidiaries (the “Recipient”).

Reference is made to the Employee Grant Details (the “Employee Grant Details”) issued to the Recipient with respect to the applicable Award, which may be found on the Solium Shareworks system at https://Shareworks.Solium.com (or any successor system selected by II-VI) (the “Solium Shareworks System”). Reference further is made to the prospectus relating to the Plan (as defined below), which also may be found on the Solium Shareworks System.

All capitalized terms used herein, to the extent not defined herein, shall have the meanings set forth in the II-VI 2018 Omnibus Incentive Plan (as amended and/or restated from time to time, the “Plan”), a copy of which can be found on the Solium Shareworks System, and/or the applicable Employee Grant Details. Terms of the Plan and the Employee Grant Details are incorporated herein by reference. This Agreement shall constitute an Award Agreement as that term is defined in the Plan.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, and intending to be legally bound hereby, the Recipient and II-VI agree as follows:

1.Performance Share Unit Award. II-VI hereby grants to the Recipient an Award of Performance Share Units under the Plan, as specified in the Employee Grant Details, to be earned based upon achievement of the Performance Objectives in accordance with Section 2 (this “Award”). For the purposes of this Award: (1) “Performance Period” shall mean the period from July

1, 2020 through and including June 30, 2023; (2) “Target Award” shall mean the Target Award set forth in the Employee Grant Details; (3) “Maximum Award” means the maximum number of Shares that may be earned under this Agreement as set forth in the Employee Grant Details, which number represents 200% of the Target Award; and (4) “Performance Share Unit” or “Unit” means the contingent right to receive the equivalent of one (1) Share, in the event the Unit vests and becomes payable pursuant to the terms of this Agreement. Units shall be payable and settled solely in Shares, except as otherwise provided in this Agreement.

2.Determination of Units Earned. Subject to Section 4 and Section 5, the Units shall be earned in accordance with the following schedule:

Exhibit 10.31

	Units Earned as a Percentage of Target Award
If II-VI Consolidated Cash Flow from Operations is less than 79.99% of the Cash Flow Target	0%
If II-VI Consolidated Cash Flow from Operations is greater than or equal to 80.00% and less than 100.00% of the Cash Flow Target	50.00% to 99.99%(1)
If II-VI Consolidated Cash Flow from Operations equals 100.00% of the Cash Flow Target	100.00%
If II-VI Consolidated Cash Flow from Operations is greater than 100.00% and less than 140.00% of the Cash Flow Target	100.01% to 199.99%(2)
If II-VI Consolidated Cash Flow from Operations is greater than or equal to 140.00% of the Cash Flow Target	200.00% (Maximum Award)

(1)In the event that the II-VI Consolidated Cash Flow from Operations is greater than or equal to 80.00% and less than 100.00% of the Cash Flow Target, the Performance Shares earned as a percentage of the Target Award will be a percentage determined on a linear basis between 50.00% and 99.99% by adding 50.00% to the product of (A) 50.00% and (B)(i) the II-VI Consolidated Cash Flow from Operations as a percentage of the Cash Flow Target less 80.00% divided by (ii) 25.0% (which product cannot exceed 49.99%).

(2)In the event that the II-VI Consolidated Cash Flow from Operations is greater than 100.00% and less than 140.00% of the Cash Flow Target, the Performance Shares earned as a percentage of the Target Award will be a percentage determined on a linear basis between 100.01% and 199.99% by adding 100.00% to the product of (A) 100.00% and (B)(i) the II-VI Consolidated Cash Flow from Operations as a percentage of the Cash Flow Target less 100.00% divided by (ii) 40.00% (which product cannot exceed 99.99%).

For the purposes of this Award: (i) “II-VI Consolidated Cash Flow from Operations” shall mean the consolidated “Net cash flow provided by operating activities” of II-VI for the Performance Period, determined in accordance with generally accepted accounting principles in the United States, consistently applied; (ii) all targets are expressed in US dollars and performance for II-VI businesses that do not use US dollars as their reporting currency will be translated into US dollars via II-VI’s financial consolidation system at the appropriate exchange rates; and (iii) “Cash Flow Target” shall mean

$1,792,000,000.00. Only whole Units shall be earned in accordance with this Section 2. By way of example and not limitation, earning 66.67% of a Target Award of 100 Units would result in 66 Units being earned and payable.

3.Payment; Dividend Equivalents. The amount determined under

Section 2 will be paid to the Recipient in Shares no later than the seventy-fifth (75th) calendar day following the end of the Performance Period. II-VI shall cause a stock certificate (or equivalent electronic book entry) representing Shares equal to the number of Units vested and payable under this Agreement to be issued to the Recipient by such date. In addition, the Recipient shall be entitled to receive, following the completion of the Performance Period but in no event later than March 15th of the calendar year following the completion of the Performance Period, a cash payment equal to the cash dividends that would have been paid during the Performance Period on the applicable number of Shares underlying the Units earned as provided in Section 2 if such Shares had been issued and outstanding during the Performance Period. Such cash dividend equivalents will not vest or be paid prior to the vesting of the Units to which they relate, as specified in this Agreement, and will be subject to cancellation and forfeiture to the same extent that the related Units do not vest or are forfeited. Notwithstanding the foregoing, the

Exhibit 10.31

Company, at its sole discretion, may settle the Award in cash if necessary or appropriate for legal or administrative reasons based on laws in the Recipient’s jurisdiction, in which case the Company shall pay to the Recipient an amount in cash equal to the product of (a) the number of Units earned in accordance with Section 2 and (b) the Fair Market Value on the day prior to the Committee’s approval of the number of Units earned following completion of the Performance Period, with such cash payment being made to the Recipient no later than the seventy fifth (75th) calendar day following the end of the Performance Period.

4.Separation from Service.

(a)General. Except as provided in Section 4(b) or Section 5 or as

may be otherwise determined by the Committee, if the Recipient’s Separation from Service occurs before the end of the Performance Period, this Award shall be forfeited on the date of such Separation from Service.

(b)Prorating in Certain Circumstances. Notwithstanding

Section 4(a), if the Recipient’s Separation from Service occurs during the

Performance Period due to the Recipient’s (i) normal retirement, as defined in IIVI’s Global Retirement Policy, (ii) death, (iii) permanent and total disability, as defined in Code Section 22(e)(3) (a “Disability”), (iv) termination by the Company or a Subsidiary that the Recipient is employed by or provides services to (the “Employer”) other than for Cause (as defined below) other than within two years following a Change in Control or (v) termination by the Recipient for Good Reason (as defined below) other than within two years following a Change in Control, but only if the Recipient’s offer letter, employment agreement or other applicable employment or service agreement with the Company or the Employer provides for severance upon Separation from Service for Good Reason (or similar term), then in each case under clauses (i) - (v) of this paragraph the Recipient shall be entitled to a prorated portion of the Units to the extent earned pursuant to Section 2, determined at the end of the Performance Period and based on the ratio of the number of complete months the Recipient was employed or served (as applicable) during the Performance Period to the total number of months in the Performance Period. In the event of the death of the Recipient, delivery of the applicable number of Shares shall be made to the Recipient’s estate as soon as administratively practicable after the end of the Performance Period. Notwithstanding any provision of this Agreement, if the Company receives a legal opinion that, due to a legal judgment and/or development in the Recipient’s jurisdiction, the potential pro-rated vesting that applies to this Award upon a Recipient’s normal retirement would be deemed unlawful or discriminatory, the provisions of this Section 4(b)(i) regarding the vesting of this Award if the Recipient’s Separation from Service is as a result of normal retirement will not be applicable to the Recipient and the remaining provisions of this Agreement will govern.

5.Change in Control; Adjustments to Payments.

(a)Change in Control. Upon a Change in Control, the Award shall

be subject to Section 10 of the Plan, with “Cause” and “Good Reason” for such purpose as defined below.

(b)“Cause” shall be defined as that term is defined in the Recipient’s offer letter, employment agreement or other applicable employment or service agreement with the Company; or, if there is no such definition, “Cause” shall mean a determination by the Company that any of the following has occurred:

(i)the willful failure by the Recipient to perform the Recipient’s duties and responsibilities to the Company or the Employer (other than any such failure resulting from the Recipient’s Disability), which is not cured within ten (10) business days of receiving written notice from the Company or the Employer specifying in reasonable detail the duties or responsibilities that the Company or the Employer believes are not being adequately performed;

(ii)the willful engaging by the Recipient in any act that is

damaging to the Company or the Employer;

Exhibit 10.31

(iii)the conviction of the Recipient of, or a plea of “guilty” or

“no contest” to, (A) any felony or (B) a criminal offense involving fraud, dishonesty or other moral turpitude;

(iv)any breach by the Recipient of the terms of any written

agreement between the Recipient and the Company relating to proprietary information, confidentiality, non-disclosure, ownership of inventions, noncompetition, non-solicitation, non-interference or non-disparagement;

(v)the engaging by the Recipient in any willful act of

dishonesty resulting or intended to result, directly or indirectly, in personal gain to the Recipient; or

(vi)the commission of any act by the Recipient that is in

violation of the Company’s Code of Business Conduct and Ethics.

(c)“Good Reason” shall be defined as that term is defined in the Recipient’s offer letter, employment agreement or other applicable employment or service agreement with the Company; or, if there is no such definition, “Good

Reason” shall mean that any of the following has occurred, without the Recipient’s express written consent:

(i)a material reduction of the Recipient’s employment

responsibilities from those immediately prior to the Change in Control;

(ii)a material reduction by the Company or the Employer of

the Recipient’s eligibility for Total Target Compensation as in effect immediately prior to the Change in Control, with “Total Target Compensation” defined as the

Recipient’s annual base salary plus the cash and stock compensation the Recipient is eligible to receive from the Company or the Employer at one hundred percent (100%) performance, whether sales incentive, bonus or otherwise;

(iii)a material increase in the amount of the Recipient’s

business travel that produces a constructive relocation of the Recipient;

(iv)a material reduction by the Company or the Employer in

the kind or level of employee benefits to which the Recipient is entitled immediately prior to the Change in Control, with the result that the Recipient’s overall benefits package is materially reduced; or

(v)the relocation of the Recipient to a facility or a location

more than thirty (30) miles from the Recipient’s principal place of employment immediately prior to the Change in Control.

In order for the Recipient to incur a Separation from Service for Good Reason, (A) the Company must be notified by the Recipient in writing within ninety (90) days of the event constituting Good Reason, (B) the event must remain uncorrected by the Company or the Employer (as applicable) for thirty (30) days following such notice (the “Notice Period”), and (C) such Separation from Service must occur within sixty (60) days after the expiration of the Notice Period.

(d)Adjustments to Payments.

(i)Notwithstanding any provision to the contrary in this Agreement, if it is determined that any payment or distribution by the Company or the Employer to the Recipient or for the Recipient’s benefit (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise) (the

Exhibit 10.31

“Payments”) would be subject to the excise tax imposed by Code Section 4999, or any interest or penalty is incurred by the Recipient with respect to such excise tax (such excise tax, together with any such interest and penalties, collectively referred to as the “Excise Tax”), then the Payments shall be reduced (but not below zero) if and to the extent that such reduction would result in the Recipient retaining a larger amount, on an after-tax basis (taking into account federal, state and local income taxes and the imposition of the Excise Tax), than if the Recipient received all of the Payments. The Company shall reduce or eliminate the Payments by first reducing or eliminating the portion of the Payments that are not payable in cash and then by reducing or eliminating cash payments, in each case in reverse order beginning with payments or benefits that are to be paid the farthest in time from the determination.

(ii)All determinations required to be made under this Section 5(d), including whether and when an adjustment to any Payments is required and, if applicable, which Payments are to be so adjusted, shall be made by an independent accounting firm selected by II-VI from among the four (4) largest accounting firms in the United States or any nationally-recognized financial planning and benefits consulting company (the “Accounting Firm”), which shall provide detailed supporting calculations both to II-VI and to the Recipient within fifteen (15) business days of the receipt of notice from the

Recipient that there has been a Payment, or such earlier time as is requested by II-VI. In the event that the Accounting Firm is serving as accountant or auditor for the individual, entity or group effecting the Change in Control, II-VI shall appoint another nationally-recognized accounting firm to make the determinations required hereunder (which accounting firm shall then be referred to as the Accounting Firm hereunder). All fees and expenses of the Accounting

Firm shall be borne solely by II-VI. If the Accounting Firm determines that no Excise Tax is payable by the Recipient, it shall furnish the Recipient with a written opinion that failure to report the Excise Tax on the Recipient’s applicable federal income tax return would not result in the imposition of a negligence or similar penalty. Any determination by the Accounting Firm shall be binding upon the Company and the Recipient.

6.Nontransferability. Except as otherwise provided in the Plan, the Units shall not be sold, pledged, assigned, hypothecated, transferred or disposed of (a “Transfer”) in any manner, other than by will or the laws of descent and distribution. Any attempt to Transfer the Units in violation of this Section or the Plan shall render this Award null and void.

7.Adjustments. Upon any event described in Section 12 of the Plan

(entitled “Adjustments”) or any successor provision thereto, the terms of such Section 12 of the Plan or any successor provision thereto shall apply to this Award.

8.Fractional Shares. II-VI shall not be required to issue any fractional Shares pursuant to this Award, and II-VI may round fractional Shares down to the nearest whole Share.

9.Responsibility for Taxes.

(a)Regardless of any action the Company or the Employer takes

with respect to any or all income tax, social insurance, payroll tax, fringe benefit tax, payment on account or other tax-related items related to the Recipient’s participation in the Plan (“Tax-Related Items”), the Recipient acknowledges that the ultimate liability for all Tax-Related Items owed by the Recipient is and remains the Recipient’s responsibility and that the Company (i) makes no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of this Award, including the grant or vesting of this Award or the subsequent sale of Shares acquired pursuant to this Award; and (ii) does not commit to structure the terms of the grant or any aspect of this Award to reduce or eliminate the Recipient’s liability for Tax-Related Items or achieve a particular tax result. Further, if the Recipient is subject to Tax-Related Items in more than one jurisdiction, the

Exhibit 10.31

Recipient acknowledges and agrees that the Company or the Employer may be required to withhold or account for TaxRelated Items in more than one jurisdiction.

(b)Prior to any relevant taxable or tax withholding event, as

applicable the Recipient agrees to make adequate arrangements satisfactory to the Company to satisfy all Tax-Related Items. In this regard, the Recipient authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy any applicable withholding obligations with regard to TaxRelated Items by one or a combination of the following: (i) withholding from the

Recipient’s wages or other cash compensation paid to the Recipient by the

Company or the Employer; (ii) withholding from the proceeds of the sale of

Shares acquired upon vesting of this Award either through a voluntary sale or through a mandatory sale arranged by the Company (on the Recipient’s behalf pursuant to this authorization) without further consent; (iii) withholding Shares to be issued upon vesting of this Award; or (iv) any other method determined by the Committee and permitted by applicable laws. Notwithstanding the foregoing, if the Recipient is subject to the short-swing profit rules of Section 16(b) of the Exchange Act, the Company will withhold in Shares issuable at vesting of the Award upon the relevant withholding event, unless otherwise determined by the Committee.

(c)The Company may withhold or account for Tax-Related Items

by considering applicable withholding rates, including maximum applicable rates, in which case the Recipient may receive a refund of any over-withheld amount in cash (with no entitlement to the equivalent in Shares), or, if not refunded, the Recipient may seek a refund from the local tax authorities. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, the Recipient is deemed to have been issued the full number of Shares, notwithstanding that a number of Shares are held back solely for the purpose of paying the Tax-Related Items.

(d)Finally, the Recipient shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of the Recipient’s participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to issue or deliver Shares or the proceeds from the sale of Shares, if the Recipient fails to comply with the Recipient’s obligations in connection with the Tax-Related Items, as described in this Section 9.

10.Plan Provisions. In the event of any conflict between the provisions of this Agreement and the Plan, the Plan shall control, except that capitalized terms specifically defined in this Agreement shall have the meaning given to them in this Agreement with respect to their usage in this Agreement, notwithstanding the definitions given to such terms in the Plan (which definitions shall control as they relate to the usage of such terms in the Plan).

11.No Continued Rights. The granting of this Award shall not give the Recipient any rights to similar grants in future years or any right to continuance of employment or other service with II-VI or its Subsidiaries, nor shall it interfere in any way with any right that the Company or the Employer would otherwise have to terminate the Recipient’s employment or other services at any time, or the right of the Recipient to terminate his or her employment or other service at any time.

12.Rights Unsecured. The Recipient shall have only II-VI’s unfunded, unsecured promise to pay pursuant to the terms of this Agreement. The rights of the Recipient hereunder shall be that of a general unsecured creditor of II-VI and the Recipient shall not have any security interest in any assets of II-VI.

13.Non-Competition; Non-Solicitation; Confidentiality.

(a)While the Recipient is employed by the Company (including its Subsidiaries) and for a period of one (1) year after the Recipient’s Separation from Service for any reason (the “Restricted Period”), the Recipient will not directly or indirectly:

Exhibit 10.31

(i)engage in any business or enterprise (whether as owner,

partner, officer, director, employee, consultant, investor, lender or otherwise, except as the holder of not more than one percent (1%) of the outstanding stock of a publicly-held company), that develops, manufactures, markets or sells any product or service that competes with any product or service developed, manufactured, marketed or sold or, to the Recipient’s knowledge, planned to be developed, manufactured, marketed or sold, by II-VI or its Subsidiaries while the Recipient was employed by the Company or a Subsidiary, within the United States of America, and/or any other country within which II-VI or its Subsidiaries have customers or prospective customers as of the date of such Separation from Service;

(ii)(A) solicit for the purpose of selling or distributing any

products or services that are the same or similar to those developed, manufactured, marketed or sold by II-VI or its Subsidiaries, (1) any customers of II-VI or its Subsidiaries, (2) any prospective customers known by the Recipient to have been solicited by II-VI or its Subsidiaries within the twelve (12) months prior to the Recipient’s Separation from Service, or (3) any distributors, sales agents or other third-parties who sell to or refer potential customers in need of the types of products and services produced, marketed, licensed, sold or provided by II-VI or its Subsidiaries who have become known to the Recipient as a result of his/her employment with the Company (including its Subsidiaries), or (B) induce or attempt to induce any vendor, supplier, licensee or other business relation of II-VI or its Subsidiaries to cease or restrict doing business with II-VI or its Subsidiaries, or in any way interfere with the relationship between any such vendor, supplier, licensee or business relation and II-VI or its Subsidiaries; or

(iii)either alone or in association with others (A) solicit, or

permit any organization directly or indirectly controlled by the Recipient to solicit, any employee of II-VI or its Subsidiaries to leave the employ of II-VI or its Subsidiaries, or (B) solicit for employment, hire or engage as an independent contractor, or permit any organization directly or indirectly controlled by the Recipient to solicit for employment, hire or engage as an independent contractor, any person who was employed by II-VI or its Subsidiaries at any time during the term of the Recipient’s employment with the Company or a Subsidiary; provided that this clause (B) shall not apply to any individual whose employment with II-VI or its Subsidiaries has been terminated for a period of one (1) year or longer.

(b)The Recipient acknowledges that certain materials, including

information, data, technology and other materials relating to customers, programs, costs, marketing, investment, sales activities, promotion, credit and financial data, manufacturing processes, financing methods, plans or the business and affairs of II-VI and its Subsidiaries constitute proprietary confidential information and trade secrets. Accordingly, the Recipient will not at any time during or after the Recipient’s employment with the Company or a Subsidiary disclose or use for the Recipient’s own benefit or purposes or the benefit or purposes of any other person, firm, partnership, joint venture, association, corporation or other business organization, entity or enterprise, other than the Company (including its Subsidiaries), any proprietary confidential information or trade secrets; provided that the foregoing shall not apply to information which is not unique to II-VI and its Subsidiaries or which is generally known to the industry or the public other than as a result of the Recipient’s breach of this covenant. The Recipient agrees that, upon the Recipient’s Separation from Service for any reason, the Recipient will immediately return to II-VI all property of II-VI and its Subsidiaries, including all memoranda, books, technical and/or lab notebooks, customer product and pricing data, papers, plans, information, letters and other data, and all copies thereof or therefrom, which in any way relate to the business of II-VI and its Subsidiaries, except that the Recipient may retain personal items. The Recipient further agrees that the Recipient will not retain or use for the Recipient’s account at any time any trade names, trademark or other proprietary business designation used or owned in connection with the business of II-VI and its Subsidiaries.

(c)The Restricted Period will be tolled during and for any period

of time during which the Recipient is in violation of the restrictive covenants contained in this Section 13 and for any period of time which may be necessary to secure an order of court or injunction, either preliminary or permanent, to enforce such covenants, such that the cumulative time period during which the Recipient is in compliance with the restrictive covenants contained in Section 13 will not exceed the one (1)-year period set forth above.

Exhibit 10.31

(d)Nothing herein is intended to or shall limit, prevent, impede

or interfere with the Recipient’s non-waivable right, without prior notice to the Company, to provide information to the government, participate in investigations, testify in proceedings regarding the Company’s past or future conduct, or engage in any activities protected under whistleblower statutes, or to receive and fully retain a monetary award from a government-administered whistleblower award program for providing information directly to a government agency. Further, the Recipient understands that pursuant to the Defend Trade Secrets Act of 2016, the Recipient shall not be held criminally, or civilly, liable under any Federal or State trade secret law for the disclosure of a trade secret that is made in confidence either directly or indirectly to a Federal, State, or local government official, or an attorney, for the sole purpose of reporting, or investigating, a violation of law. Moreover, the Recipient understands that he or she may disclose trade secrets in a complaint, or other document, filed in a lawsuit, or other proceeding, if such filing is made under seal. Finally, the Recipient understands that if he or she files a lawsuit alleging retaliation by the Company for reporting a suspected violation of the law, the Recipient may disclose the trade secret to the attorney and use the trade secret in the court proceeding, so long as any document containing the trade secret is filed under seal and the Recipient does not disclose the trade secret except pursuant to court order.

14.Remedies; Clawback.

(a)II-VI and the Recipient acknowledge and agree that that any

violation by the Recipient of any of the restrictive covenants contained in Section 13 would cause immediate, material and irreparable harm to the II-VI and its Subsidiaries which may not adequately be compensated by money damages and, therefore, II-VI and its Subsidiaries shall be entitled to injunctive relief (including one (1) or more preliminary injunctions and/or ex parte restraining orders) in addition to, and not in derogation of, any other remedies provided by law, in equity or otherwise for such a violation, including the right to have such covenants specifically enforced by any court of competent jurisdiction, the rights under Section 14(b), and the right to require the Recipient to account for and pay over to II-VI all benefits derived or received by the Recipient as a result of any such breach of covenant together with interest thereon, from the date of such initial violation until such sums are received by II-VI.

(b)In the event that the Recipient violates or breaches any of the

covenants set forth in Section 13, the Units and the right to receive Shares in exchange for such Units shall be forfeited. II-VI shall also have the right, in its sole discretion, in addition to any other remedies or damages provided by law, in equity or otherwise, to demand and require the Recipient (i) to the extent that any cash payment was received with respect to such Units, to return and transfer to II-VI any such cash payment, (ii) to the extent that any Shares were received with respect to such Units, to return and transfer to II-VI any such shares directly or beneficially owned by the Recipient, and (iii) to the extent that the Recipient sold or transferred any such Shares, to disgorge and/or repay to II-VI any profits or other economic value (as determined by II-VI) made or realized by the Recipient with respect to such Shares, including the value of any gift thereof.

(c)     This Award, and any amounts or benefits received or outstanding under the Plan, as well as any other incentive awards

previously granted to the Recipient by the Company, shall be subject to potential clawback, cancellation, recoupment, rescission, payback, reduction, or other similar action in accordance with the terms or conditions of any applicable Company clawback or similar policy or any applicable law related to such actions, as may be in effect from time to time, including the requirements of (a) Section 304 of the Sarbanes Oxley Act and Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, (b) similar rules under the laws of any other jurisdiction, and (c) any policies adopted by the Company to implement such requirements. The Recipient acknowledges and consents to the Company’s application, implementation and enforcement of any applicable Company clawback or similar policy that may apply to the Recipient, whether adopted prior to or following the Grant Date, and any provision of applicable law relating to clawback, cancellation, recoupment, rescission, payback, or reduction of compensation, and agrees that the Company may take such actions as may be necessary to effectuate any such policy or applicable law, without further consideration or action.

Exhibit 10.31

15.Recipient Acknowledgments. The Recipient acknowledges and agrees that (a) as a result of the Recipient’s previous, current and future employment with the Company or the Employer, the Recipient has had access to, will have access to and/or possesses or will possess confidential and proprietary information of II-VI and its Subsidiaries, (b) II-VI and its Subsidiaries are engaged in a highly competitive business and conduct such business worldwide, (c) this Agreement does not constitute a contract of employment, does not imply that the Company or the Employer will continue the Recipient’s employment for any period of time and does not change the at-will nature of the Recipient’s employment, except as set forth in a separate written employment agreement between the Company or the Employer and the Recipient, (d) the restrictive covenants set forth in Section 13 are necessary and reasonable in time and scope (including the period, geographic, product and service and other restrictions) to protect the legitimate business interests of II-VI and its Subsidiaries, (e) the remedy, forfeiture and payment provisions contained in Section 14 are reasonable and necessary to protect the legitimate business interests of II-VI and its Subsidiaries, (f) acceptance of this Award and these Units and agreement to be bound by the provisions hereof is not a condition of the Recipient’s employment and (g) the Recipient’s receipt of the benefits provided under this Agreement is adequate consideration for the enforcement of the provisions contained in Section 13 and Section 14.

16.Severability; Waiver. If any term, provision, covenant or restriction contained in this Agreement is held by a court or a federal regulatory agency of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions contained in this Agreement shall remain in full force and effect, and shall in no way be affected, impaired or invalidated. In particular, in the event that any of such provisions shall be adjudicated to exceed the time, geographic, product and service or other limitations permitted by applicable law in any jurisdiction, then such provisions shall be deemed reformed in such jurisdiction to the maximum time, geographic, product and service or other limitations permitted by applicable law. No delay or omission by II-VI in exercising any right under this Agreement will operate as a waiver of that or any other right. A waiver or consent given by II-VI on any one occasion is effective only in that instance and will not be construed as a bar to or waiver of any right on any other occasion.

17.Notice. II-VI may require any notice required or permitted under this Agreement to be transmitted, submitted or received, by II-VI or the Recipient, via the Solium Shareworks System in accordance with the procedures established by II-VI for such notice. Otherwise, except as otherwise set forth in the Agreement, any written notice required or permitted by this Agreement shall be mailed, certified mail (return receipt requested) or by overnight carrier, to II-VI at the following address:

II-VI Incorporated

or to the Recipient at his or her most recent home address on record with II-VI. Notices are effective upon receipt.

18.Controlling Law. The validity, construction and effect of this

Agreement will be determined in accordance with the internal laws of the Commonwealth of Pennsylvania without giving effect to the conflict of laws principles thereof. The Recipient and II-VI hereby irrevocably submit to the exclusive jurisdiction of the state and Federal courts located in the Commonwealth of Pennsylvania and consent to the jurisdiction of any such court, provided, however, that, notwithstanding anything to the contrary set forth above, II-VI may file an action to enforce the covenants contained in Section 13 by seeking injunctive or other equitable relief in any appropriate court having jurisdiction, including where the Recipient resides or where the Recipient was employed by the Company or the Employer. The Recipient and IIVI also both irrevocably waive, to the fullest extent permitted by applicable law, any objection either may now or hereafter have to the laying of venue of any such dispute brought or injunctive or equitable relief sought in such court or any defense of inconvenient forum for the maintenance of such dispute and consent to the personal jurisdiction of any such court. For purposes of this Section 18, the Employer shall be a third-party beneficiary of this Agreement.

Exhibit 10.31

Notwithstanding anything to the contrary set forth in this Agreement, any restrictive covenants contained in this Agreement are independent, and are not intended to limit the enforceability, of any restrictive or other covenants contained in any other agreement between the Company or the Employer and the Recipient.

20.Captions; Section References. Section and other headings contained in this Agreement are for reference purposes only and are in no way intended to describe, interpret, define or limit the scope, extent or intent of this Agreement or any provision hereof.

22.Section 409A. This Agreement and this Award are intended to satisfy all applicable requirements of Section 409A or an exception thereto and shall be construed accordingly. II-VI may in its sole discretion, and without the consent of the Recipient, take any action it deems necessary to comply with the requirements of Section 409A or an exception thereto, including amending the terms of this Award and this Agreement, in any manner it deems necessary to cause this Award and this Agreement to be excepted from Section 409A (or to comply therewith to the extent that II-VI determines that it is not excepted). Notwithstanding, the Recipient recognizes and acknowledges that Section 409A may affect the timing and recognition of payments due hereunder, and may impose upon the Recipient certain taxes or other charges for which the Recipient is and shall remain solely responsible.

23.Assignment. Except as provided in Section 6, the Recipient’s rights and obligations under this Agreement shall not be transferable by the Recipient, by assignment or otherwise, and any purported assignment, transfer or delegation thereof by the Recipient shall be void.

26.Compliance with Legal Requirements. Notwithstanding any other provisions of the Plan or this Agreement, unless there is an exemption from any registration, qualification or other legal requirement applicable to the Shares, the Company shall not be required to deliver any Shares issuable upon vesting of this Award prior to the completion of any registration or qualification of the Shares under any local, state, federal or foreign securities or exchange control law or under rulings or regulations of the U.S. Securities and Exchange Commission (“SEC”) or of

Exhibit 10.31

any other governmental regulatory body, or prior to obtaining any approval or other clearance from any local, state, federal or foreign governmental agency, which registration, qualification or approval the Company shall, in its absolute discretion, deem necessary or advisable. Further, the Company is under no obligation to register or qualify the Shares with the SEC or any state or foreign securities commission or to seek approval or clearance from any governmental authority for the issuance or sale of Shares. Subject to Section 409A, the Committee may postpone the issuance or delivery of Shares under this Award as the Committee may consider appropriate and may require the Recipient to make such representations and furnish such information as it may consider appropriate in connection with the issuance or delivery of Shares in compliance with applicable laws, rules and regulations.

Exhibit 10.31

Appendix A

General Terms Applicable to Awards Granted to Recipients Outside the U.S.

This Appendix A includes additional terms and conditions applicable to all grants of Awards under the Plan to employees or other grant recipients who reside outside the United States. Capitalized terms used but not defined in this Appendix A shall have the meanings given to them in this Agreement or the Plan.

1.DATA PRIVACY INFORMATION AND CONSENT

The Company is located at 375 Saxonburg Blvd., Saxonburg, PA 16056, USA and grants employees of the Company and its Subsidiaries the opportunity to participate in the Plan at the Company’s sole discretion. If the Recipient would like to participate in the Plan, the Recipient should review the following information about the Company’s data processing practices and declare his or her consent.

(a) Data Collection and Usage. The Company collects, processes and uses the Recipient’s personal data, including the Recipient’s name, home address and telephone number, date of birth, social insurance number or other identification number, salary, citizenship, job title, any Shares or directorships held in the Company, and details of all awards canceled, vested, or outstanding in the Recipient’s favor, which the Company receives from the Recipient or the Employer. If the Company offers the Recipient an opportunity to participate in the Plan, then the Company will collect the Recipient’s personal data for purposes of allocating stock and implementing, administering and managing the Plan. The Company’s legal basis for the processing of the Recipient’s personal data would be the Recipient’s consent.

(b)Stock Plan Administration Service Providers and International Data

Transfers. The Company and its service providers are based in the United States. If the Recipient is outside the United States, the Recipient should note that his or her country has enacted data privacy laws that are different from the United States. The Company transfers participant data to Solium Capital, an independent service provider based in the United States, which assists the Company with the implementation, administration and management of the Plan. In the future, the Company may select a different service provider and share the Recipient’s data with another company that serves in a similar manner. The Company’s service provider will open an account for the Recipient. The Recipient will be asked to agree on separate terms and data processing practices with the service provider, which is a condition to the Recipient’s ability to participate in the Plan. The Company’s legal basis for the transfer of the Recipient’s personal data is the Recipient’s consent.

Page 13 of #NUM_PAGES#

109919762v2

Exhibit 10.31

(c) Data Retention. The Company will use the Recipient’s personal data only as long as is necessary to implement, administer and manage the Recipient’s participation in the Plan or as required to comply with legal or regulatory obligations, including under tax and security laws. When the Company no longer needs the Recipient’s personal data, which will generally be seven years after the Recipient participates in the Plan, the Company will remove it from its systems. If the Company keeps the data longer, it would be to satisfy legal or regulatory obligations and the Company’s legal basis would be relevant laws or regulation.

(d)Voluntariness and Consequence of Consent Denial or Withdrawal. The Recipient’s participation in the Plan and his or her grant of consent is purely voluntary. The Recipient may deny or withdraw his or her consent at any time. If the Recipient does not consent, or if the Recipient withdraws his or her consent, the Recipient cannot participate in the Plan. This would not affect the Recipient’s salary as an employee; the Recipient would merely forfeit the opportunities associated with the Plan.

(e) Data Subject Rights. The Recipient has a number of rights under data privacy laws in the Recipient’s country. Depending on where the Recipient is based, the Recipient’s rights may include the right to (i) request access or copies of personal data the Company processes, (ii) rectification of incorrect data, (iii) deletion of data, (iv) restrictions on processing, (v) portability of data, (vi) to lodge complaints with competent authorities in the Recipient’s country, and/or (vii) a list with the names and addresses of any potential recipients of the Recipient’s personal data. To receive clarification regarding the Recipient’s rights or to exercise such rights, the Recipient should contact the Company at HR Department, Director of Compensation and Benefits, 375 Saxonburg Blvd., Saxonburg, PA 16056, USA.

If the Recipient agrees with the data processing practices as described in this notice and would like to participate in the Plan, please declare the Recipient’s consent by clicking “Accept” on the Solium Shareworks system award acceptance page or by signing this Agreement.

The Recipient acknowledges that he or she is sufficiently proficient in English, or has consulted with an advisor who is sufficiently proficient in English, so as to allow the Recipient to understand the terms and conditions of this Agreement. Furthermore, if the Recipient has received this Agreement or any other document related to this Award and/or the Plan translated into a language other than English and if the meaning of the translated version is different than the English version, the English version will control.

4.INSIDER TRADING/MARKET ABUSE LAWS

The Recipient acknowledges that, depending on his or her country of residence, or the designated broker’s country or where the Shares are listed, the Recipient may be subject to insider trading restrictions and/or market abuse laws, which may affect the Recipient’s ability to accept, acquire, sell, attempt to sell or otherwise dispose of Shares or right to Shares (e.g., Awards) or rights linked to the value of Shares during such times as the Recipient is considered to have “inside information” regarding the Company (as defined by or determined under the laws in the applicable jurisdiction).

109919762v2

Exhibit 10.31

which may include fellow employees (other than on a “need to know” basis) and (ii) “tipping” third parties or causing them to otherwise buy or sell securities. Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Company insider trading policy. The Recipient is responsible for ensuring compliance with any applicable restrictions and should consult with his or her personal legal advisor on this matter.

5.EXCHANGE CONTROL, TAX AND/OR FOREIGN ASSET/ACCOUNT REPORTING

The Recipient acknowledges that there may be exchange control, tax, foreign asset and/or account reporting requirements which may affect the Recipient’s ability to hold Shares acquired under the Plan or cash received from participating in the Plan in a brokerage/bank account or legal entity outside the Recipient’s country. The Recipient may be required to report such accounts, assets, the balances therein, the value thereof and/or the transactions related thereto to the tax or other authorities in the Recipient’s country.

Jurisdiction-Specific Terms and Conditions

Capitalized terms used but not defined in this Appendix B shall have the meanings given to them in the Agreement or the Plan.

Terms and Conditions

This Appendix B includes additional terms and conditions that govern the Award grants to the Recipient under the Plan if the Recipient works and/or resides in one of the countries or other jurisdictions listed below.

If the Recipient is a citizen or resident of a jurisdiction other than the one in which the Recipient is currently working and/or residing, is considered a resident of another jurisdiction for local law purposes or transfers employment and/or residency between countries or other jurisdictions after the Grant Date, the Company shall, in its sole discretion, determine to what extent the terms and conditions contained herein apply to the Recipient under these circumstances.

Page 17 of #NUM_PAGES#

Exhibit 10.31

Notifications

This Appendix B also includes information regarding country-specific securities laws, exchange controls, tax and certain other issues of which the Recipient should be aware with respect to the Recipient’s participation in the Plan. The information is based on the securities, exchange control and other laws in effect in the respective countries as of August 2020. Such laws are often complex and change frequently. As a result, the Company strongly recommends that the Recipient not rely on the information noted herein as the only source of information relating to the consequences of the Recipient’s participation in the Plan because the information may be out of date at the time this Award vests or the Shares acquired under the Plan are sold.

In addition, the information is general in nature and may not apply to the Recipient’s particular situation, and the Company is not in a position to assure the Recipient of any particular result. Accordingly, the Recipient should seek appropriate professional advice as to how the relevant laws in the Recipient’s country may apply to his or her situation.

Finally, if the Recipient is a citizen or resident of country other than the one in which the Recipient is currently working and/or residing, is considered a resident of another country for local law purposes or transfers employment and/or residence between countries after the Grant Date, the information contained herein may not be applicable in the same manner to the Recipient.

AUSTRALIA

Terms and Conditions

Offer. The Company is pleased to provide the Recipient with this offer to participate in the Plan. This offer sets out information regarding the offer to participate in the Plan for Australian resident employees of the Company and its Subsidiaries (“Australian Recipients”). This information is provided by the Company to ensure compliance of the Plan with Australian Securities and Investments Commission (“ASIC”) Class Order 14/1000 and relevant provisions of the Corporations Act 2001.

In addition to the information set out in the Agreement and the Appendices, Australian Recipients are also being provided with copies of the following documents:

a)the Plan;

b)the Plan prospectus; and

c)the Australian Employee Tax Supplement for the Plan (collectively, the Additional Documents”).

Page 18 of #NUM_PAGES#

109919762v2

Exhibit 10.31

The Additional Documents provide further information to help Australian

Recipients make an informed investment decision about participating in the Plan. Neither the Plan nor the Plan prospectus is a prospectus for the purposes of the Corporations Act 2001.

Australian Recipients should not rely upon any oral statements made in relation to this offer. Australian Recipients should rely only upon the statements contained in the Agreement, including the Appendices, and the Additional Documents when considering participation in the Plan.

Securities Law Notification. Investment in Shares involves a degree of risk. Eligible employees who elect to participate in the Plan should monitor their participation and consider all risk factors relevant to the purchase of Shares under the Plan as set forth below and in the Additional Documents.

The information herein is general information only. It is not advice or information that takes into account Australian Recipients’ objectives, financial situation and needs.

Australian Recipients should consider obtaining their own financial product advice from a person who is licensed by ASIC to give such advice.

Additional Risk Factors for Australian Residents. Australian Recipients should have regard to risk factors relevant to investment in securities generally and, in particular, to holding Shares. For example, the price at which an individual Share is quoted on the Nasdaq Global Select Market (“Nasdaq”) may increase or decrease due to a number of factors. There is no guarantee that the price of a Share will increase. Factors that may affect the price of an individual Share include fluctuations in the domestic and international market for listed stocks, general economic conditions, including interest rates, inflation rates, commodity and oil prices, changes to government fiscal, monetary or regulatory policies, legislation or regulation, the nature of the markets in which the Company operates and general operational and business risks.

More information about potential factors that could affect the Company’s business and financial results will be included in the Company’s most recent Annual Report on Form 10-K and the Company’s Quarterly Report on Form 10Q. Copies of these reports are available at http://www.sec.gov/, on the Company’s “Investors” page at https://www.ii-vi.com/investor-relations/, and upon request to the Company.

In addition, Australian Recipients should be aware that the Australian dollar (“AUD”) value of any Shares purchased under the Plan will be affected by the USD/AUD exchange rate. Participation in the Plan involves certain risks related to fluctuations in this rate of exchange.

Exhibit 10.31

Common Stock in a U.S. Corporation. Common stock of a U.S. corporation is analogous to ordinary shares of an Australian corporation. Each holder of a Share is entitled to one vote.

Ascertaining the Market Price of Common Stock. Australian Recipients may ascertain the current market price of the Common Stock as traded on the Nasdaq under the symbol “IIVI” at http://www.nasdaq.com/symbol/iivi/realtime. The Australian dollar equivalent of that price can be obtained at: http://www.rba.gov.au/statistics/frequency/exchange-rates.html.

This will not be a prediction of what the market price per share of common stock will be when the Units vest or when the shares of common stock are issued or of the applicable exchange rate on the actual vesting date or date the shares of common stock are issued.

Notifications

Foreign Asset and Account Reporting Notification. If the Recipient is a Canadian resident, the Recipient may be required to report his or her foreign property if the total cost of the foreign property exceeds a specified threshold (currently CAD 100,000) at any time during the year. Foreign property includes Shares acquired under the Plan and may include the Units. The Units must be reported - generally at a nil cost - if the cost threshold is exceeded because of other foreign property the Recipient holds. If Shares are acquired, their cost generally is the adjusted cost base (“ACB”) of the Shares. The ACB ordinarily would equal the fair market value of the Shares at the time of acquisition, but if the Recipient owns other Shares, the ACB may have to be averaged with the ACB of the other Shares. The Recipient should consult with his or her personal tax advisor to determine the Recipient’s personal reporting obligations.

Resale of Shares. If the Recipient acquires Shares under the Plan, any subsequent offer of such Shares for sale is required to occur outside of Canada.

The Recipient acknowledges that the Company’s designated broker is under no obligation to arrange for the sale of Shares at any particular price. Upon the

Page 23 of #NUM_PAGES#

sale of Shares, the Company agrees to pay the Recipient the cash proceeds from the sale of Shares, less any brokerage fees or commissions and subject to any obligation to satisfy Tax-Related Items.

The Recipient understands that if they fail to set up such account or fail to provide the requested details to the Company, the Recipient might not be able to receive sale proceeds or delivery of proceeds may be delayed. If the proceeds from the sale of the Recipient's Shares are converted to local currency, the Recipient acknowledges that the Company is under no obligation to secure any particular exchange conversion rate, and the Company may face delays in converting the proceeds to local currency due to exchange control restrictions in China. The Recipient agrees to bear any currency fluctuation risk between the date the Stock Units vest and the Shares are sold and the time that (i) the Tax-Related Items are converted to local currency and remitted to the tax authorities, and (ii) net proceeds are converted to local currency and distributed to the Recipient. The Recipient acknowledges that the Company and any Subsidiary or Affiliate cannot be held liable for any delay in delivering the proceeds to the Recipient. The Recipient agrees to sign any agreements, forms and/or consents that may be reasonably requested by the Company (or the Company’s designated broker) to effectuate any of the remittances, transfers,

PERFORMANCE SHARE UNIT AWARD AGREEMENT

(RELATIVE TSR; SHARE-SETTLED)

THIS PERFORMANCE SHARE UNIT AWARD AGREEMENT, including any general and jurisdiction-specific terms and conditions for the Recipient’s jurisdiction set forth in the appendices attached hereto, (this “Agreement”) is dated as of the Grant Date, as specified in the applicable Employee Grant Details (as defined below), by and between II-VI Incorporated, a Pennsylvania corporation (“II-VI”), and the Recipient, as specified in the applicable Employee Grant Details, who is a director, employee or consultant of II-VI or one of its Subsidiaries (the “Recipient”).

Reference is made to the Employee Grant Details (the “Employee Grant Details”) issued to the Recipient with respect to the applicable Award, which may be found on the Solium Shareworks system at https://Shareworks.Solium.com (or any successor system selected by II-VI) (the “Solium Shareworks System”). Reference further is made to the prospectus relating to the Plan (as defined below), which also may be found on the Solium Shareworks System.

All capitalized terms used herein, to the extent not defined herein, shall have the meanings set forth in the II-VI 2018 Omnibus Incentive Plan (as amended and/or restated from time to time, the “Plan”), a copy of which can be found on the Solium Shareworks System, and/or the applicable Employee Grant Details. Terms of the Plan and the Employee Grant Details are incorporated herein by reference. This Agreement shall constitute an Award Agreement as that term is defined in the Plan.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, and intending to be legally bound hereby, the Recipient and II-VI agree as follows:

1.Performance Share Unit Award. II-VI hereby grants to the Recipient an Award of Performance Share Units under the Plan, as specified in the Employee Grant Details, to be earned based upon achievement of the Performance Objectives in accordance with Section 2 (this “Award”). For the purposes of this Award: (1) “Performance Period” shall mean the period from July 1, 2020 through and including June 30, 2023;(2) “Target Award” shall mean the Target Award set forth in the Employee Grant Details; (3) “Maximum Award” means the maximum number of Shares that may be earned under this Agreement as set forth in the Employee Grant Details, which number represents 200% of the Target Award; and (4) “Performance Share Unit” or “Unit” means the contingent right to receive the equivalent of one (1) Share, in the event the Unit vests and becomes payable pursuant to the terms of this Agreement. Units shall be payable and settled solely in Shares, except as otherwise provided in this Agreement.

2.Determination of Units Earned. Subject to Section 4 and Section 5, the Units shall be earned in accordance with the following schedule:

Exhibit 10.32

	Units Earned as a Percentage of Target Award
If Cumulative TSR is below Market 50th Percentile by more than 40 percentage points	0.00%
If Cumulative TSR is equal to 40 percentage points below Market 50th Percentile and there is an absolute positive Cumulative TSR	50.00% (Threshold)
If Cumulative TSR is below Market 50th Percentile by less than 40 percentage points and there is an absolute positive Cumulative TSR	Subtract 1.25% from 100.00% for each 1% below Market 50th Percentile
If Cumulative TSR equals Market 50th Percentile	100.00%
If Cumulative TSR is above Market 50th Percentile byless than 40 percentage points	Add 2.50% to 100.00% for each 1% above Market 50th Percentile1
If Cumulative TSR is above Market 50th Percentile by more than 40 percentage points	200.00%1 (Maximum Award)

1 If there is an absolute negative Cumulative TSR for the Performance Period and Cumulative TSR is above Market 50th Percentile, the percentage of the Target Award earned shall be capped at 100.00%.

Definitions:     

“Market” is the S&P Composite 1500 – Electronic Equipment, Instruments & Components as published on July 1, 2020. If a listing is removed from the S&P Composite 1500 – Electronic Equipment, Instruments & Components during the Performance Period, it will not be replaced, nor will any listing be added for any other reason. The S&P Composite 1500 – Electronic Equipment, Instruments & Components shall be a closed group for purposes of this Program.

“Cumulative TSR” shall be based on the 30-day average closing stock price of the Shares prior to July 1, 2020 ($48.66) (“Beginning Stock Price”) and the 30-day average closing stock price of the Shares prior to July 1, 2023 (“Ending Stock Price”). Cumulative TSR shall be calculated as follows:

((Ending Stock Price minus Beginning Stock Price ($48.66) plus dividends) divided by Beginning Stock Price ($48.66))

Only whole Units shall be earned in accordance with this Section 2. By way of example and not limitation, earning 66.67% of a Target Award of 100 Units would result in 66 Units being earned and payable.

3.Payment; Dividend Equivalents. The amount determined under Section 2 will be paid to the Recipient in Shares no later than the seventy-fifth (75th) calendar day following the end of the Performance Period. II-VI shall cause a stock certificate (or equivalent electronic book entry) representing Shares equal to the number of Units vested and payable under this Agreement to be issued to the Recipient by such date. In addition, the Recipient shall be entitled to receive, following the completion of the Performance Period but in no event later than March 15th of the calendar year following the completion of the Performance Period, a cash payment equal to the cash dividends that would have been paid during the Performance Period on the applicable number of Shares underlying the Units earned as provided in Section 2 if such Shares had been issued and outstanding during the Performance Period. Such cash dividend equivalents will not vest or be paid prior to the vesting of the Units to which they relate, as specified in this Agreement, and will be subject to cancellation and forfeiture to the same extent that the related Units do not vest or are forfeited. Notwithstanding the foregoing, the Company, at its sole discretion, may settle the Award in cash if necessary or appropriate for legal or administrative reasons based on laws in the Recipient’s jurisdiction, in which case the Company shall pay to the Recipient an amount in cash equal to the product of (a) the number of Units earned in accordance with Section 2 and (b) the Fair Market Value on the day prior to the Committee’s approval of the

Exhibit 10.32

number of Units earned following completion of the Performance Period, with such cash payment being made to the Recipient no later than the seventy fifth (75th) calendar day following the end of the Performance Period.

    4.    Separation from Service.

        (a)    General. Except as provided in Section 4(b) or Section 5 or as may be otherwise determined by the Committee, if the Recipient’s Separation from Service occurs before the end of the Performance Period, this Award shall be forfeited on the date of such Separation from Service.

(b)    Prorating in Certain Circumstances. Notwithstanding Section 4(a), if the Recipient’s Separation from Service occurs during the Performance Period due to the Recipient’s (i) normal retirement, as defined in II-VI’s Global Retirement Policy, (ii) death, (iii) permanent and total disability, as defined in Code Section 22(e)(3) (a “Disability”), (iv) termination by the Company or a Subsidiary that the Recipient is employed by or provides services to (the “Employer”) other than for Cause (as defined below) other than within two years following a Change in Control or (v) termination by the Recipient for Good Reason (as defined below) other than within two years following a Change in Control, but only if the Recipient’s offer letter, employment agreement or other applicable employment or service agreement with the Company or the Employer provides for severance upon Separation from Service for Good Reason (or similar term), then in each case under clauses (i) - (v) of this paragraph the Recipient shall be entitled to a prorated portion of the Units to the extent earned pursuant to Section 2, determined at the end of the Performance Period and based on the ratio of the number of complete months the Recipient was employed or served (as applicable) during the Performance Period to the total number of months in the Performance Period. In the event of the death of the Recipient, delivery of the applicable number of Shares shall be made to the Recipient’s estate as soon as administratively practicable after the end of the Performance Period. Notwithstanding any provision of this Agreement, if the Company receives a legal opinion that, due to a legal judgment and/or development in the Recipient’s jurisdiction, the potential pro-rated vesting that applies to this Award upon a Recipient’s normal retirement would be deemed unlawful or discriminatory, the provisions of this Section 4(b)(i) regarding the vesting of this Award if the Recipient’s Separation from Service is as a result of normal retirement will not be applicable to the Recipient and the remaining provisions of this Agreement will govern.

    5.    Change in Control; Adjustments to Payments.

(a)    Change in Control. Upon a Change in Control, the Award shall be subject to Section 10 of the Plan, with “Cause” and “Good Reason” for such purpose as defined below.

(b)    “Cause” shall be defined as that term is defined in the Recipient’s offer letter, employment agreement or other applicable employment or service agreement with the Company; or, if there is no such definition, “Cause” shall mean a determination by the Company that any of the following has occurred:

(i)    the willful failure by the Recipient to perform the Recipient’s duties and responsibilities to the Company or the Employer (other than any such failure resulting from the Recipient’s Disability), which is not cured within ten (10) business days of receiving written notice from the Company or the Employer specifying in reasonable detail the duties or responsibilities that the Company or the Employer believes are not being adequately performed;

(ii)    the willful engaging by the Recipient in any act that is damaging to the Company or the Employer;

(iii)    the conviction of the Recipient of, or a plea of “guilty” or “no contest” to, (A) any felony or (B) a criminal offense involving fraud, dishonesty or other moral turpitude;

            (iv)    any breach by the Recipient of the terms of any written agreement between the Recipient and the Company relating to proprietary information, confidentiality, non-disclosure, ownership of inventions, non-competition, non-solicitation, non-interference or non-disparagement;

Exhibit 10.32

            (v)    the engaging by the Recipient in any willful act of dishonesty resulting or intended to result, directly or indirectly, in personal gain to the Recipient; or

            (vi)    the commission of any act by the Recipient that is in violation of the Company’s Code of Business Conduct and Ethics.

(c)    “Good Reason” shall be defined as that term is defined in the Recipient’s offer letter, employment agreement or other applicable employment or service agreement with the Company; or, if there is no such definition, “Good Reason” shall mean that any of the following has occurred, without the Recipient’s express written consent:

(i)    a material reduction of the Recipient’s employment responsibilities from those immediately prior to the Change in Control;

(ii)    a material reduction by the Company or the Employer of the Recipient’s eligibility for Total Target Compensation as in effect immediately prior to the Change in Control, with “Total Target Compensation” defined as the Recipient’s annual base salary plus the cash and stock compensation the Recipient is eligible to receive from the Company or the Employer at one hundred percent (100%) performance, whether sales incentive, bonus or otherwise;

(iii)    a material increase in the amount of the Recipient’s business travel that produces a constructive relocation of the Recipient;

(iv)    a material reduction by the Company or the Employer in the kind or level of employee benefits to which the Recipient is entitled immediately prior to the Change in Control, with the result that the Recipient’s overall benefits package is materially reduced; or

(v)    the relocation of the Recipient to a facility or a location more than thirty (30) miles from the Recipient’s principal place of employment immediately prior to the Change in Control.

In order for the Recipient to incur a Separation from Service for Good Reason, (A) the Company must be notified by the Recipient in writing within ninety (90) days of the event constituting Good Reason, (B) the event must remain uncorrected by the Company or the Employer (as applicable) for thirty (30) days following such notice (the “Notice Period”), and (C) such Separation from Service must occur within sixty (60) days after the expiration of the Notice Period.

(d)    Adjustments to Payments.

(i)    Notwithstanding any provision to the contrary in this Agreement, if it is determined that any payment or distribution by the Company or the Employer to the Recipient or for the Recipient’s benefit (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise) (the “Payments”) would be subject to the excise tax imposed by Code Section 4999, or any interest or penalty is incurred by the Recipient with respect to such excise tax (such excise tax, together with any such interest and penalties, collectively referred to as the “Excise Tax”), then the Payments shall be reduced (but not below zero) if and to the extent that such reduction would result in the Recipient retaining a larger amount, on an after-tax basis (taking into account federal, state and local income taxes and the imposition of the Excise Tax), than if the Recipient received all of the Payments. The Company shall reduce or eliminate the Payments by first reducing or eliminating the portion of the Payments that are not payable in cash and then by reducing or eliminating cash payments, in each case in reverse order beginning with payments or benefits that are to be paid the farthest in time from the determination.

(ii)    All determinations required to be made under this Section 5(d), including whether and when an adjustment to any Payments is required and, if applicable, which Payments are to be so adjusted, shall be made by an independent accounting firm selected by II-VI from among the four (4) largest accounting firms in the

Exhibit 10.32

United States or any nationally-recognized financial planning and benefits consulting company (the “Accounting Firm”), which shall provide detailed supporting calculations both to II-VI and to the Recipient within fifteen (15) business days of the receipt of notice from the Recipient that there has been a Payment, or such earlier time as is requested by II-VI. In the event that the Accounting Firm is serving as accountant or auditor for the individual, entity or group effecting the Change in Control, II-VI shall appoint another nationally-recognized accounting firm to make the determinations required hereunder (which accounting firm shall then be referred to as the Accounting Firm hereunder). All fees and expenses of the Accounting Firm shall be borne solely by II-VI. If the Accounting Firm determines that no Excise Tax is payable by the Recipient, it shall furnish the Recipient with a written opinion that failure to report the Excise Tax on the Recipient’s applicable federal income tax return would not result in the imposition of a negligence or similar penalty. Any determination by the Accounting Firm shall be binding upon the Company and the Recipient.

    6.    Nontransferability. Except as otherwise provided in the Plan, the Units shall not be sold, pledged, assigned, hypothecated, transferred or disposed of (a “Transfer”) in any manner, other than by will or the laws of descent and distribution. Any attempt to Transfer the Units in violation of this Section or the Plan shall render this Award null and void.

    7.     Adjustments. Upon any event described in Section 12 of the Plan (entitled “Adjustments”) or any successor provision thereto, the terms of such Section 12 of the Plan or any successor provision thereto shall apply to this Award.

    8.    Fractional Shares. II-VI shall not be required to issue any fractional Shares pursuant to this Award, and II-VI may round fractional Shares down to the nearest whole Share.

    9.     Responsibility for Taxes.

(a)Regardless of any action the Company or the Employer takes with respect to any or all income tax, social insurance, payroll tax, fringe benefit tax, payment on account or other tax-related items related to the Recipient’s participation in the Plan (“Tax-Related Items”), the Recipient acknowledges that the ultimate liability for all Tax-Related Items owed by the Recipient is and remains the Recipient’s responsibility and that the Company (i) makes no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of this Award, including the grant or vesting of this Award or the subsequent sale of Shares acquired pursuant to this Award; and (ii) does not commit to structure the terms of the grant or any aspect of this Award to reduce or eliminate the Recipient’s liability for Tax-Related Items or achieve a particular tax result. Further, if the Recipient is subject to Tax-Related Items in more than one jurisdiction, the Recipient acknowledges and agrees that the Company or the Employer may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

(b)Prior to any relevant taxable or tax withholding event, as applicable the Recipient agrees to make adequate arrangements satisfactory to the Company to satisfy all Tax-Related Items. In this regard, the Recipient authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy any applicable withholding obligations with regard to Tax-Related Items by one or a combination of the following: (i) withholding from the Recipient’s wages or other cash compensation paid to the Recipient by the Company or the Employer; (ii) withholding from the proceeds of the sale of Shares acquired upon vesting of this Award either through a voluntary sale or through a mandatory sale arranged by the Company (on the Recipient’s behalf pursuant to this authorization) without further consent; (iii) withholding Shares to be issued upon vesting of this Award; or (iv) any other method determined by the Committee and permitted by applicable laws. Notwithstanding the foregoing, if the Recipient is subject to the short-swing profit rules of Section 16(b) of the Exchange Act, the Company will withhold in Shares issuable at vesting of the Award upon the relevant withholding event, unless otherwise determined by the Committee.

(c)The Company may withhold or account for Tax-Related Items by considering applicable withholding rates, including maximum applicable rates, in which case the Recipient may receive a refund of any over-withheld amount in cash (with no entitlement to the equivalent in Shares), or, if not refunded, the Recipient may seek

Exhibit 10.32

a refund from the local tax authorities. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, the Recipient is deemed to have been issued the full number of Shares, notwithstanding that a number of Shares are held back solely for the purpose of paying the Tax-Related Items.

(d)Finally, the Recipient shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of the Recipient’s participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to issue or deliver Shares or the proceeds from the sale of Shares, if the Recipient fails to comply with the Recipient’s obligations in connection with the Tax-Related Items, as described in this Section 9.

    10.    Plan Provisions. In the event of any conflict between the provisions of this Agreement and the Plan, the Plan shall control, except that capitalized terms specifically defined in this Agreement shall have the meaning given to them in this Agreement with respect to their usage in this Agreement, notwithstanding the definitions given to such terms in the Plan (which definitions shall control as they relate to the usage of such terms in the Plan).

    11.    No Continued Rights. The granting of this Award shall not give the Recipient any rights to similar grants in future years or any right to continuance of employment or other service with II-VI or its Subsidiaries, nor shall it interfere in any way with any right that the Company or the Employer would otherwise have to terminate the Recipient’s employment or other services at any time, or the right of the Recipient to terminate his or her employment or other service at any time.

    12.    Rights Unsecured. The Recipient shall have only II-VI’s unfunded, unsecured promise to pay pursuant to the terms of this Agreement. The rights of the Recipient hereunder shall be that of a general unsecured creditor of II-VI and the Recipient shall not have any security interest in any assets of II-VI.

    13.    Non-Competition; Non-Solicitation; Confidentiality.

        (a)    While the Recipient is employed by the Company (including its Subsidiaries) and for a period of one (1) year after the Recipient’s Separation from Service for any reason (the “Restricted Period”), the Recipient will not directly or indirectly:

            (i)    engage in any business or enterprise (whether as owner, partner, officer, director, employee, consultant, investor, lender or otherwise, except as the holder of not more than one percent (1%) of the outstanding stock of a publicly-held company), that develops, manufactures, markets or sells any product or service that competes with any product or service developed, manufactured, marketed or sold or, to the Recipient’s knowledge, planned to be developed, manufactured, marketed or sold, by II-VI or its Subsidiaries while the Recipient was employed by the Company or a Subsidiary, within the United States of America, and/or any other country within which II-VI or its Subsidiaries have customers or prospective customers as of the date of such Separation from Service;

            (ii)     (A) solicit for the purpose of selling or distributing any products or services that are the same or similar to those developed, manufactured, marketed or sold by II-VI or its Subsidiaries, (1) any customers of II-VI or its Subsidiaries, (2) any prospective customers known by the Recipient to have been solicited by II-VI or its Subsidiaries within the twelve (12) months prior to the Recipient’s Separation from Service, or (3) any distributors, sales agents or other third-parties who sell to or refer potential customers in need of the types of products and services produced, marketed, licensed, sold or provided by II-VI or its Subsidiaries who have become known to the Recipient as a result of his/her employment with the Company (including its Subsidiaries), or (B) induce or attempt to induce any vendor, supplier, licensee or other business relation of II-VI or its Subsidiaries to cease or restrict doing business with II-VI or its Subsidiaries, or in any way interfere with the relationship between any such vendor, supplier, licensee or business relation and II-VI or its Subsidiaries; or

            (iii)    either alone or in association with others (A) solicit, or permit any organization directly or indirectly controlled by the Recipient to solicit, any employee of II-VI or its Subsidiaries to leave the

Exhibit 10.32

employ of II-VI or its Subsidiaries, or (B) solicit for employment, hire or engage as an independent contractor, or permit any organization directly or indirectly controlled by the Recipient to solicit for employment, hire or engage as an independent contractor, any person who was employed by II-VI or its Subsidiaries at any time during the term of the Recipient’s employment with the Company or a Subsidiary; provided that this clause (B) shall not apply to any individual whose employment with II-VI or its Subsidiaries has been terminated for a period of one (1) year or longer.

        (b)    The Recipient acknowledges that certain materials, including information, data, technology and other materials relating to customers, programs, costs, marketing, investment, sales activities, promotion, credit and financial data, manufacturing processes, financing methods, plans or the business and affairs of II-VI and its Subsidiaries constitute proprietary confidential information and trade secrets. Accordingly, the Recipient will not at any time during or after the Recipient’s employment with the Company or a Subsidiary disclose or use for the Recipient’s own benefit or purposes or the benefit or purposes of any other person, firm, partnership, joint venture, association, corporation or other business organization, entity or enterprise, other than the Company (including its Subsidiaries), any proprietary confidential information or trade secrets; provided that the foregoing shall not apply to information which is not unique to II-VI and its Subsidiaries or which is generally known to the industry or the public other than as a result of the Recipient’s breach of this covenant. The Recipient agrees that, upon the Recipient’s Separation from Service for any reason, the Recipient will immediately return to II-VI all property of II-VI and its Subsidiaries, including all memoranda, books, technical and/or lab notebooks, customer product and pricing data, papers, plans, information, letters and other data, and all copies thereof or therefrom, which in any way relate to the business of II-VI and its Subsidiaries, except that the Recipient may retain personal items. The Recipient further agrees that the Recipient will not retain or use for the Recipient’s account at any time any trade names, trademark or other proprietary business designation used or owned in connection with the business of II-VI and its Subsidiaries.

(c)    The Restricted Period will be tolled during and for any period of time during which the Recipient is in violation of the restrictive covenants contained in this Section 13 and for any period of time which may be necessary to secure an order of court or injunction, either preliminary or permanent, to enforce such covenants, such that the cumulative time period during which the Recipient is in compliance with the restrictive covenants contained in Section 13 will not exceed the one (1)-year period set forth above.

(d)     Nothing herein is intended to or shall limit, prevent, impede or interfere with the Recipient’s non-waivable right, without prior notice to the Company, to provide information to the government, participate in investigations, testify in proceedings regarding the Company’s past or future conduct, or engage in any activities protected under whistleblower statutes, or to receive and fully retain a monetary award from a government-administered whistleblower award program for providing information directly to a government agency. Further, the Recipient understands that pursuant to the Defend Trade Secrets Act of 2016, the Recipient shall not be held criminally, or civilly, liable under any Federal or State trade secret law for the disclosure of a trade secret that is made in confidence either directly or indirectly to a Federal, State, or local government official, or an attorney, for the sole purpose of reporting, or investigating, a violation of law. Moreover, the Recipient understands that he or she may disclose trade secrets in a complaint, or other document, filed in a lawsuit, or other proceeding, if such filing is made under seal. Finally, the Recipient understands that if he or she files a lawsuit alleging retaliation by the Company for reporting a suspected violation of the law, the Recipient may disclose the trade secret to the attorney and use the trade secret in the court proceeding, so long as any document containing the trade secret is filed under seal and the Recipient does not disclose the trade secret except pursuant to court order.

14.    Remedies; Clawback.

(a)    II-VI and the Recipient acknowledge and agree that that any violation by the Recipient of any of the restrictive covenants contained in Section 13 would cause immediate, material and irreparable harm to the II-VI and its Subsidiaries which may not adequately be compensated by money damages and, therefore, II-VI and its Subsidiaries shall be entitled to injunctive relief (including one (1) or more preliminary injunctions and/or ex parte restraining orders) in addition to, and not in derogation of, any other remedies provided by law, in equity or otherwise for such a violation, including the right to have such covenants specifically enforced by any court of competent jurisdiction, the rights under Section 14(b), and the right to require the Recipient to account for and pay over to II-VI

Exhibit 10.32

all benefits derived or received by the Recipient as a result of any such breach of covenant together with interest thereon, from the date of such initial violation until such sums are received by II-VI.

        (b)    In the event that the Recipient violates or breaches any of the covenants set forth in Section 13, the Units and the right to receive Shares in exchange for such Units shall be forfeited. II-VI shall also have the right, in its sole discretion, in addition to any other remedies or damages provided by law, in equity or otherwise, to demand and require the Recipient (i) to the extent that any cash payment was received with respect to such Units, to return and transfer to II-VI any such cash payment, (ii) to the extent that any Shares were received with respect to such Units, to return and transfer to II-VI any such shares directly or beneficially owned by the Recipient, and (iii) to the extent that the Recipient sold or transferred any such Shares, to disgorge and/or repay to II-VI any profits or other economic value (as determined by II-VI) made or realized by the Recipient with respect to such Shares, including the value of any gift thereof.

    (c)     This Award, and any amounts or benefits received or outstanding under the Plan, as well as any other incentive awards previously granted to the Recipient by the Company, shall be subject to potential clawback, cancellation, recoupment, rescission, payback, reduction, or other similar action in accordance with the terms or conditions of any applicable Company clawback or similar policy or any applicable law related to such actions, as may be in effect from time to time, including the requirements of (a) Section 304 of the Sarbanes Oxley Act and Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, (b) similar rules under the laws of any other jurisdiction, and (c) any policies adopted by the Company to implement such requirements. The Recipient acknowledges and consents to the Company’s application, implementation and enforcement of any applicable Company clawback or similar policy that may apply to the Recipient, whether adopted prior to or following the Grant Date, and any provision of applicable law relating to clawback, cancellation, recoupment, rescission, payback, or reduction of compensation, and agrees that the Company may take such actions as may be necessary to effectuate any such policy or applicable law, without further consideration or action.

15.    Recipient Acknowledgments. The Recipient acknowledges and agrees that (a) as a result of the Recipient’s previous, current and future employment with the Company or the Employer, the Recipient has had access to, will have access to and/or possesses or will possess confidential and proprietary information of II-VI and its Subsidiaries, (b) II-VI and its Subsidiaries are engaged in a highly competitive business and conduct such business worldwide, (c) this Agreement does not constitute a contract of employment, does not imply that the Company or the Employer will continue the Recipient’s employment for any period of time and does not change the at-will nature of the Recipient’s employment, except as set forth in a separate written employment agreement between the Company or the Employer and the Recipient, (d) the restrictive covenants set forth in Section 13 are necessary and reasonable in time and scope (including the period, geographic, product and service and other restrictions) to protect the legitimate business interests of II-VI and its Subsidiaries, (e) the remedy, forfeiture and payment provisions contained in Section 14 are reasonable and necessary to protect the legitimate business interests of II-VI and its Subsidiaries, (f) acceptance of this Award and these Units and agreement to be bound by the provisions hereof is not a condition of the Recipient’s employment and (g) the Recipient’s receipt of the benefits provided under this Agreement is adequate consideration for the enforcement of the provisions contained in Section 13 and Section 14.

    16.    Severability; Waiver. If any term, provision, covenant or restriction contained in this Agreement is held by a court or a federal regulatory agency of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions contained in this Agreement shall remain in full force and effect, and shall in no way be affected, impaired or invalidated. In particular, in the event that any of such provisions shall be adjudicated to exceed the time, geographic, product and service or other limitations permitted by applicable law in any jurisdiction, then such provisions shall be deemed reformed in such jurisdiction to the maximum time, geographic, product and service or other limitations permitted by applicable law. No delay or omission by II-VI in exercising any right under this Agreement will operate as a waiver of that or any other right. A waiver or consent given by II-VI on any one occasion is effective only in that instance and will not be construed as a bar to or waiver of any right on any other occasion.

Exhibit 10.32

    17.    Notice. II-VI may require any notice required or permitted under this Agreement to be transmitted, submitted or received, by II-VI or the Recipient, via the Solium Shareworks System in accordance with the procedures established by II-VI for such notice. Otherwise, except as otherwise set forth in the Agreement, any written notice required or permitted by this Agreement shall be mailed, certified mail (return receipt requested) or by overnight carrier, to II-VI at the following address:

    18.    Controlling Law. The validity, construction and effect of this Agreement will be determined in accordance with the internal laws of the Commonwealth of Pennsylvania without giving effect to the conflict of laws principles thereof. The Recipient and II-VI hereby irrevocably submit to the exclusive jurisdiction of the state and Federal courts located in the Commonwealth of Pennsylvania and consent to the jurisdiction of any such court, provided, however, that, notwithstanding anything to the contrary set forth above, II-VI may file an action to enforce the covenants contained in Section 13 by seeking injunctive or other equitable relief in any appropriate court having jurisdiction, including where the Recipient resides or where the Recipient was employed by the Company or the Employer. The Recipient and II-VI also both irrevocably waive, to the fullest extent permitted by applicable law, any objection either may now or hereafter have to the laying of venue of any such dispute brought or injunctive or equitable relief sought in such court or any defense of inconvenient forum for the maintenance of such dispute and consent to the personal jurisdiction of any such court. For purposes of this Section 18, the Employer shall be a third-party beneficiary of this Agreement.

    19.    Entire Agreement. This Agreement (including the Plan and the Employee Grant Details) contains the entire understanding between the parties and supersedes any prior understanding and agreements between them regarding the subject matter hereof with respect to this Award, and there are no other representations, agreements, arrangements or understandings, oral or written, between the parties relating to this Award which are not fully expressed herein. Notwithstanding anything to the contrary set forth in this Agreement, any restrictive covenants contained in this Agreement are independent, and are not intended to limit the enforceability, of any restrictive or other covenants contained in any other agreement between the Company or the Employer and the Recipient.

    20.     Captions; Section References. Section and other headings contained in this Agreement are for reference purposes only and are in no way intended to describe, interpret, define or limit the scope, extent or intent of this Agreement or any provision hereof. Unless expressly provided otherwise, any reference in this Agreement to any Section refers to the corresponding Section of this Agreement.

    21.    Limitation of Actions. Any lawsuit commenced by the Recipient with respect to any matter arising out of or relating to this Agreement must be filed no later than one (1) year after the date that a denial of any claim hereunder is made or any earlier date that the claim otherwise accrues.

    22.    Section 409A. This Agreement and this Award are intended to satisfy all applicable requirements of Section 409A or an exception thereto and shall be construed accordingly. II-VI may in its sole discretion, and without the consent of the Recipient, take any action it deems necessary to comply with the requirements of Section 409A or an exception thereto, including amending the terms of this Award and this Agreement, in any manner it deems necessary to cause this Award and this Agreement to be excepted from Section 409A (or to comply therewith to the extent that II-VI determines that it is not excepted). Notwithstanding, the Recipient recognizes and acknowledges that Section 409A may affect the timing and recognition of payments due hereunder, and may impose upon the Recipient certain taxes or other charges for which the Recipient is and shall remain solely responsible.

Exhibit 10.32

    23.    Assignment. Except as provided in Section 6, the Recipient’s rights and obligations under this Agreement shall not be transferable by the Recipient, by assignment or otherwise, and any purported assignment, transfer or delegation thereof by the Recipient shall be void. II-VI may assign/delegate all or any portion of this Agreement and its rights hereunder without prior notice to the Recipient and without the Recipient providing any additional consent thereto, whereupon the Recipient shall continue to be bound hereby with respect to such assignee/delegatee.

    24.    Electronic Delivery. II-VI may, in its sole discretion, deliver any documents or correspondence related to this Agreement, the Units, the Plan, the Recipient’s participation in the Plan or future awards that may be granted to the Recipient under the Plan, by electronic means. The Recipient hereby consents to receive such documents by electronic delivery and to the Recipient’s participation in the Plan through an on-line or electronic system established and maintained by II-VI or another third party designated by II-VI, including the Solium Shareworks System. Likewise, II-VI may require the Recipient to deliver or receive any documents or correspondence related to this Agreement by such electronic means.

    25.     Further Assurances. The Company and the Recipient shall use commercially reasonable efforts to, from time to time at the request of the other party, without any additional consideration, furnish the other party such further information or assurances, execute and deliver such additional documents and take such other actions and do such other things, as may be necessary to carry out the provisions of this Agreement.

    26.     Compliance with Legal Requirements. Notwithstanding any other provisions of the Plan or this Agreement, unless there is an exemption from any registration, qualification or other legal requirement applicable to the Shares, the Company shall not be required to deliver any Shares issuable upon vesting of this Award prior to the completion of any registration or qualification of the Shares under any local, state, federal or foreign securities or exchange control law or under rulings or regulations of the U.S. Securities and Exchange Commission (“SEC”) or of any other governmental regulatory body, or prior to obtaining any approval or other clearance from any local, state, federal or foreign governmental agency, which registration, qualification or approval the Company shall, in its absolute discretion, deem necessary or advisable. Further, the Company is under no obligation to register or qualify the Shares with the SEC or any state or foreign securities commission or to seek approval or clearance from any governmental authority for the issuance or sale of Shares. Subject to Section 409A, the Committee may postpone the issuance or delivery of Shares under this Award as the Committee may consider appropriate and may require the Recipient to make such representations and furnish such information as it may consider appropriate in connection with the issuance or delivery of Shares in compliance with applicable laws, rules and regulations. The Recipient understands and agrees that the Company shall have unilateral authority to amend this Agreement without his or her consent to the extent necessary to comply with securities or other laws applicable to the issuance of Shares.

    27.     Appendices. The Recipient acknowledges and agrees that, if the Recipient resides outside the U.S., this Award is subject to the general terms applicable to Awards granted to recipients outside the U.S. set forth in Appendix A hereto. Further, this Award is subject to any additional terms and conditions set forth for the Recipient’s U.S. state or country in Appendix B hereto. Appendix A and Appendix B constitute part of this Agreement.

28.    Imposition of Other Requirements. The Company reserves the right to impose other requirements on this Award to the extent that the Company determines that it is necessary or advisable in order to comply with local law or facilitate the administration of this Award and to require the Recipient to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

29.    No Advice Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding the Recipient’s participation in the Plan or the Recipient’s acquisition or sale of Shares. The Recipient understands and agrees that the Recipient should consult with his or her own personal legal and financial advisors regarding the Recipient’s participation in the Plan before taking any action related to the Plan.

Exhibit 10.32

Appendix A

General Terms Applicable to Awards Granted to Recipients Outside the U.S.

This Appendix A includes additional terms and conditions applicable to all grants of Awards under the Plan to employees or other grant recipients who reside outside the United States. Capitalized terms used but not defined in this Appendix A shall have the meanings given to them in this Agreement or the Plan.

1.DATA PRIVACY INFORMATION AND CONSENT

The Company is located at 375 Saxonburg Blvd., Saxonburg, PA 16056, USA and grants employees of the Company and its Subsidiaries the opportunity to participate in the Plan at the Company’s sole discretion. If the Recipient would like to participate in the Plan, the Recipient should review the following information about the Company’s data processing practices and declare his or her consent.

(a)Data Collection and Usage. The Company collects, processes and uses the Recipient’s personal data, including the Recipient’s name, home address and telephone number, date of birth, social insurance number or other identification number, salary, citizenship, job title, any Shares or directorships held in the Company, and details of all awards canceled, vested, or outstanding in the Recipient’s favor, which the Company receives from the Recipient or the Employer. If the Company offers the Recipient an opportunity to participate in the Plan, then the Company will collect the Recipient’s personal data for purposes of allocating stock and implementing, administering and managing the Plan. The Company’s legal basis for the processing of the Recipient’s personal data would be the Recipient’s consent.

(b)Stock Plan Administration Service Providers and International Data Transfers. The Company and its service providers are based in the United States. If the Recipient is outside the United States, the Recipient should note that his or her country has enacted data privacy laws that are different from the United States. The Company transfers participant data to Solium Capital, an independent service provider based in the United States, which assists the Company with the implementation, administration and management of the Plan. In the future, the Company may select a different service provider and share the Recipient’s data with another company that serves in a similar manner. The Company’s service provider will open an account for the Recipient. The Recipient will be asked to agree on separate terms and data processing practices with the service provider, which is a condition to the Recipient’s ability to participate in the Plan. The Company’s legal basis for the transfer of the Recipient’s personal data is the Recipient’s consent.

(c)Data Retention. The Company will use the Recipient’s personal data only as long as is necessary to implement, administer and manage the Recipient’s participation in the Plan or as required to comply with legal or regulatory obligations, including under tax and security laws. When the Company no longer needs the Recipient’s personal data, which will generally be seven years after the Recipient participates in the Plan, the Company will remove it from its systems. If the Company keeps the data longer, it would be to satisfy legal or regulatory obligations and the Company’s legal basis would be relevant laws or regulation.

(d)Voluntariness and Consequence of Consent Denial or Withdrawal. The Recipient’s participation in the Plan and his or her grant of consent is purely voluntary. The Recipient may deny or withdraw his or her consent at any time. If the Recipient does not consent, or if the Recipient withdraws his or her consent, the Recipient cannot participate in the Plan. This would not affect the Recipient’s salary as an employee; the Recipient would merely forfeit the opportunities associated with the Plan.

(e)Data Subject Rights. The Recipient has a number of rights under data privacy laws in the Recipient’s country. Depending on where the Recipient is based, the Recipient’s rights may include the right to (i) request access or copies of personal data the Company processes, (ii) rectification of incorrect data, (iii) deletion of data, (iv) restrictions on processing, (v) portability of data, (vi) to lodge complaints with competent authorities in the

Exhibit 10.32

Recipient’s country, and/or (vii) a list with the names and addresses of any potential recipients of the Recipient’s personal data. To receive clarification regarding the Recipient’s rights or to exercise such rights, the Recipient should contact the Company at HR Department, Director of Compensation and Benefits, 375 Saxonburg Blvd., Saxonburg, PA 16056, USA.

If the Recipient agrees with the data processing practices as described in this notice and would like to participate in the Plan, please declare the Recipient’s consent by clicking “Accept” on the Solium Shareworks system award acceptance page or by signing this Agreement.

Appendix B

Jurisdiction-Specific Terms and Conditions

Capitalized terms used but not defined in this Appendix B shall have the meanings given to them in the Agreement or the Plan.

Terms and Conditions

This Appendix B includes additional terms and conditions that govern the Award grants to the Recipient under the Plan if the Recipient works and/or resides in one of the countries or other jurisdictions listed below.

If the Recipient is a citizen or resident of a jurisdiction other than the one in which the Recipient is currently working and/or residing, is considered a resident of another jurisdiction for local law purposes or transfers employment and/or residency between countries or other jurisdictions after the Grant Date, the Company shall, in its sole discretion, determine to what extent the terms and conditions contained herein apply to the Recipient under these circumstances.

Notifications

This Appendix B also includes information regarding country-specific securities laws, exchange controls, tax and certain other issues of which the Recipient should be aware with respect to the Recipient’s participation in the Plan. The information is based on the securities, exchange control and other laws in effect in the respective countries as of August 2020. Such laws are often complex and change frequently. As a result, the Company strongly recommends that the Recipient not rely on the information noted herein as the only source of information relating to the consequences of the Recipient’s participation in the Plan because the information may be out of date at the time this Award vests or the Shares acquired under the Plan are sold.

In addition, the information is general in nature and may not apply to the Recipient’s particular situation, and the Company is not in a position to assure the Recipient of any particular result. Accordingly, the Recipient should seek appropriate professional advice as to how the relevant laws in the Recipient’s country may apply to his or her situation.

Finally, if the Recipient is a citizen or resident of country other than the one in which the Recipient is currently working and/or residing, is considered a resident of another country for local law purposes or transfers employment and/or residence between countries after the Grant Date, the information contained herein may not be applicable in the same manner to the Recipient.

AUSTRALIA

Terms and Conditions

Offer. The Company is pleased to provide the Recipient with this offer to participate in the Plan. This offer sets out information regarding the offer to participate in the Plan for Australian resident employees of the Company and its Subsidiaries (“Australian Recipients”). This information is provided by the Company to ensure compliance of the Plan with Australian Securities and Investments Commission (“ASIC”) Class Order 14/1000 and relevant provisions of the Corporations Act 2001.

In addition to the information set out in the Agreement and the Appendices, Australian Recipients are also being provided with copies of the following documents:

a)the Plan;

b)the Plan prospectus; and

c)the Australian Employee Tax Supplement for the Plan (collectively, the Additional Documents”).

Exhibit 10.32

The Additional Documents provide further information to help Australian Recipients make an informed investment decision about participating in the Plan. Neither the Plan nor the Plan prospectus is a prospectus for the purposes of the Corporations Act 2001.

Australian Recipients should not rely upon any oral statements made in relation to this offer. Australian Recipients should rely only upon the statements contained in the Agreement, including the Appendices, and the Additional Documents when considering participation in the Plan.

Securities Law Notification. Investment in Shares involves a degree of risk. Eligible employees who elect to participate in the Plan should monitor their participation and consider all risk factors relevant to the purchase of Shares under the Plan as set forth below and in the Additional Documents.

The information herein is general information only. It is not advice or information that takes into account Australian Recipients’ objectives, financial situation and needs.

Australian Recipients should consider obtaining their own financial product advice from a person who is licensed by ASIC to give such advice.

Additional Risk Factors for Australian Residents. Australian Recipients should have regard to risk factors relevant to investment in securities generally and, in particular, to holding Shares. For example, the price at which an individual Share is quoted on the Nasdaq Global Select Market (“Nasdaq”) may increase or decrease due to a number of factors. There is no guarantee that the price of a Share will increase. Factors that may affect the price of an individual Share include fluctuations in the domestic and international market for listed stocks, general economic conditions, including interest rates, inflation rates, commodity and oil prices, changes to government fiscal, monetary or regulatory policies, legislation or regulation, the nature of the markets in which the Company operates and general operational and business risks.

More information about potential factors that could affect the Company’s business and financial results will be included in the Company’s most recent Annual Report on Form 10-K and the Company’s Quarterly Report on Form 10-Q. Copies of these reports are available at http://www.sec.gov/, on the Company’s “Investors” page at https://www.ii-vi.com/investor-relations/, and upon request to the Company.

In addition, Australian Recipients should be aware that the Australian dollar (“AUD”) value of any Shares purchased under the Plan will be affected by the USD/AUD exchange rate. Participation in the Plan involves certain risks related to fluctuations in this rate of exchange.

Common Stock in a U.S. Corporation. Common stock of a U.S. corporation is analogous to ordinary shares of an Australian corporation. Each holder of a Share is entitled to one vote. Further, Shares are not liable to any further calls for payment of capital or for other assessment by the Company and have no sinking fund provisions, pre-emptive rights, conversion rights or redemption provisions.

Ascertaining the Market Price of Common Stock. Australian Recipients may ascertain the current market price of the Common Stock as traded on the Nasdaq under the symbol “IIVI” at http://www.nasdaq.com/symbol/iivi/real-time. The Australian dollar equivalent of that price can be obtained at: http://www.rba.gov.au/statistics/frequency/exchange-rates.html.

This will not be a prediction of what the market price per share of common stock will be when the Units vest or when the shares of common stock are issued or of the applicable exchange rate on the actual vesting date or date the shares of common stock are issued.

Nature of Business and Summary of Significant Accounting Policies

Nature of Business and Summary of Significant Accounting Policies

Nature of Business. II-VI Incorporated and its subsidiaries (the “Company,” “we,” “us,” or “our”), a global leader in engineered materials and optoelectronic components and devices, is a vertically-integrated manufacturing company that develops, manufactures and markets engineered materials and optoelectronic components and devices for precision use in industrial materials processing, optical communications, aerospace and defense, consumer electronics, semiconductor capital equipment, life sciences and automotive applications. 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 the Company’s manufacturing yields. The Company has not experienced significant production delays due to a shortage of materials. However, the Company does occasionally experience problems associated with vendor-supplied materials not meeting specifications for quality or purity. A significant failure of the Company’s suppliers to deliver sufficient quantities of necessary high-quality materials on a timely basis could have a material adverse effect on the Company’s results of operations.

In March 2020, the World Health Organization declared the outbreak of COVID-19 as a pandemic, which continues to spread throughout the United States and world. The Company is closely monitoring the impact of the COVID-19 pandemic on all aspects of our business including the impact to our suppliers and customers as well as the impact to the countries and markets in which II-VI operates. At the onset of the COVID-19 outbreak, the Company began focusing intensely on mitigating the adverse impacts of COVID-19 on foreign and domestic operations starting by protecting its employees, suppliers and customers.

Principles of Consolidation. The Consolidated Financial Statements include the accounts of the Company. All intercompany transactions and balances have been eliminated.

Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those 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 and Cash Equivalents. The Company considers highly liquid investment instruments with an original maturity of three months or less to be cash equivalents. We place our cash and cash equivalents with high credit quality financial institutions and to date have not experienced credit losses in these instruments.

Accounts Receivable. The Company makes estimates evaluating its allowance for doubtful accounts. The Company continuously monitors collections and payments from its customers and maintains a provision for estimated credit losses based upon its historical experience, current market conditions and any specific customer collection issues that it has identified.

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, if applicable, other factors, including known trends, market conditions, currency exchange rates and other such issues. The Company generally records 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. The Company reviews its

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 20 years and 3 to 20 years for machinery and equipment.

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 the Company's right to use an underlying asset for the lease term, and lease liabilities represent the Company's 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. The Company uses 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. The Company has 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 13 for additional information.

Business Combinations. The Company accounts for business acquisitions 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.

On August 20, 2020, the Company acquired all of the outstanding shares of Ascatron AB ("Ascatron"), located in Sweden and on October 1, 2020, the Company acquired the remaining 6.1% interest in INNOViON Corporation ("Innovion"). Refer to Note 4 Acquisitions for further information regarding the Innovion and Ascatron acquisitions.

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. The Company tests 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 the Company’s reporting units to the recorded value (including goodwill). The Company uses a discounted cash flow (“DCF”) model and/or a market analysis to determine the fair value of its 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.

The Company has the option to perform a qualitative assessment of goodwill prior to completing the quantitative assessment described above to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill and other intangible assets. If the Company concludes that this is the case, it must perform the quantitative assessment. Otherwise, the Company will forego the quantitative assessment and does not need to perform any further testing. As of April 1 of fiscal years 2021 and 2020, the Company completed its annual impairment tests of its reporting units using the quantitative assessment. Based on the results of these analyses the Company’s goodwill was not impaired.

Intangibles. Intangible assets are initially recorded at their cost or fair value upon acquisition. Finite-lived intangible assets are amortized for financial reporting purposes using the straight-line method over the estimated useful lives of the assets ranging from 3 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.

Investments in Other Entities. In the normal course of business, the Company enters into various types of investment arrangements, each having unique terms and conditions. These investments may include equity interests held by the Company in business entities, including general or limited partnerships, contractual ventures, or other forms of equity participation. The Company determines whether such investments involve a variable interest entity (“VIE”) based on the characteristics of the subject entity. If the entity is determined to be a VIE, then management determines if the Company is the primary beneficiary of the entity and whether or not consolidation of the VIE is required. The primary beneficiary consolidating the VIE must normally have both (i) the power to direct the activities of a VIE that most significantly affect the VIE’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE, in either case that could potentially be significant to the VIE. When the Company is deemed to be the primary beneficiary, the VIE is consolidated and the other party’s equity interest in the VIE is accounted for as a noncontrolling interest.

The Company generally accounts for investments it makes in VIEs in which it has determined that it does not have a controlling financial interest but has significant influence over or holds at least a 20% ownership interest using the equity method. Any such investment not meeting the parameters to be accounted under the equity method would be accounted for under ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. If an entity fails to meet the characteristics of a VIE, management then evaluates such entity under the voting model. Under the voting model, management consolidates the entity if they determine that the Company, directly or indirectly, has greater than 50% of the voting shares and determines that other equity holders do not have substantive participating rights.

Series A Mandatory Convertible Preferred Stock. The II-VI Series A Mandatory Convertible Preferred Stock is initially measured at fair value, less underwriting discounts and commissions and offering expenses paid by the Company. The Preferred Stock’s dividends are cumulative, at 6% per annum.

Series B Convertible Preferred Stock. The II-VI Series B-1 Convertible Preferred Stock is 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 Available to the Common Shareholder.

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. Legal costs incurred in connection with loss contingencies are expensed as incurred. Such accruals 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. The Company had no material loss contingency liabilities at June 30, 2021 related to commitments and contingencies.

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.

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.

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 the Company’s customer have been satisfied and control has transferred to the customer. The Company has elected the practical expedient to exclude all taxes from the measurement of the transaction price.

For contracts with commercial customers, which comprise the majority of the Company’s performance obligations, ownership of the goods and associated revenue are transferred to customers at a point in time, generally upon shipment of a product to the

customer or receipt of the product by 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.

Contracts with the U.S. government through its prime contractors are typically for products or services with no alternative future use to the Company with an enforceable right to payment for performance completed to date, whereas commercial contracts typically have alternative use. Customized products with no alternative future use to the Company with an enforceable right to payment for performance completed to date are recorded over time utilizing the output method of units delivered. The Company considers this to be a faithful depiction of the transfer to the customer of revenue over time due to short cycle time and immaterial work-in-process balances. The majority of contracts typically require payment within 30 to 90 days after transfer of ownership to the customer.

Service revenue includes repairs, non-recurring engineering, 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. Non-recurring engineering arrangements are typically recognized over time under 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. The majority of contracts typically require payment within 90 days.

The Company's revenue recognition policy is consistently applied across the Company's segments, product lines, services, and geographical locations. For the periods covered herein, the Company measures revenue based on the amount of consideration it 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. The Company determines 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, the Company expenses 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. The Company has elected to recognize the costs for freight and shipping when control over products has transferred to the customer as an expense in cost of goods sold.

The Company monitors and tracks the amount of product returns and reduces revenue at the time of shipment for the estimated amount of future returns, based on historical experience.

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

The Company believes 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 5. Revenue from Contracts with Customers.

Research and Development. Research and development 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 research and development expenses as incurred.

Share-Based Compensation. Share-based compensation arrangements require the recognition in net earnings (loss) of the grant date fair value of stock compensation (for equity-classified awards). The Company recognizes 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 the Company’s historical experience of pre-vesting cancellations. The Company 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.

Accumulated Other Comprehensive Income (Loss). Accumulated other comprehensive income (loss) 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. Accumulated other comprehensive income (loss) is a component of shareholders’ equity and consists of accumulated foreign currency translation adjustments, changes in the fair value of interest rate swap derivative instruments, and pension adjustments.

Fair Value Measurements. The Company applies 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, the Company considers the principal or most advantageous market in which the Company 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.

Recently Issued Financial Accounting Standards

Recently Issued Financial Accounting Standards

Financial Instruments - Credit Losses

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, Financial Instruments - Credit Losses (Topic 326), which modifies the measurement of expected credit losses on certain types of financial instruments, including trade receivables. The Company adopted this standard on July 1, 2020. The adoption did not have a material impact on the Company's consolidated financial statements.

Pronouncements Currently Under Evaluation

In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40) ("ASU 2020-06"). The update simplifies the accounting for convertible instruments by eliminating two accounting models (i.e., the cash conversion model and beneficial conversion feature model) and reducing the number of embedded conversion features that could be recognized separately from the host contract. ASU 2020-06 also enhances transparency and improves disclosures for convertible instruments and earnings per share guidance. ASC 2020-06 is effective for annual reporting periods beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. This update permits the use of either the modified retrospective or fully retrospective method of transition. We plan to adopt this ASU as of July 1, 2021. We estimate the impact of adopting ASU 2020-06 will result in an increase in net debt of $15 million, a decrease in the deferred tax liability of $3 million, a decrease in common stock of $56 million, and an increase in retained earnings of $45 million. The adoption will result in a decrease of interest expense of approximately $12 million in fiscal year 2022.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients to ease the potential burden of accounting for the effects of reference rate reform as it pertains to contract modifications of debt and lease contracts and derivative contracts identified in a hedging relationship. These amendments are effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Company is in the process of evaluating the impact of the pronouncement.

Pending Coherent Acquisitions

12 Months Ended

Business Combination and Asset Acquisition [Abstract]

Pending Coherent Acquisition

Pending Coherent Acquisition

On March 25, 2021, II-VI, Coherent, Inc., and Watson Merger Sub Inc., a wholly owned subsidiary of II-VI (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”). Pursuant to the terms of the Merger Agreement, and subject to the conditions set forth therein, Merger Sub will be merged with and into Coherent, and Coherent will continue as the surviving corporation in the merger and wholly owned subsidiary of II-VI (the “Merger”).

Pursuant to the terms of the Merger Agreement, and subject to the conditions set forth therein, at the effective time of the Merger (the “Effective Time”), each share of common stock of Coherent, par value $0.01 per share (the “Coherent Common Stock”), issued and outstanding immediately prior to the Effective Time will be canceled and extinguished and automatically converted into the right to receive the following consideration (collectively, the “Merger Consideration”):

(A) $220.00 in cash, without interest (the “Cash Consideration”), and

(B) 0.91 of a validly issued, fully paid and nonassessable share of common stock of II-VI, no par value per share (“II-VI Common Stock”)

Pursuant to the terms of the Merger Agreement, each Coherent restricted stock unit award (a “Coherent RSU”), other than Director RSUs (as defined below), outstanding immediately prior to the Effective Time will be automatically converted into

time-based restricted stock units denominated in shares of II-VI Common Stock entitling the holder to receive, upon settlement, a number of shares of II-VI Common Stock equal to the number of shares of Coherent Common Stock subject to the Coherent RSU multiplied by the sum of (A) 0.91, and (B) the quotient obtained by dividing the Cash Consideration by the volume weighted average price of a share of II-VI Common Stock for a 10 trading day period ending prior to the closing of the Merger (the “Closing”). For Coherent RSUs subject to performance-based vesting conditions and metrics, the number of shares of II-VI Common Stock subject to the converted Coherent RSUs will be determined after giving effect to the Coherent Board of Directors’ determination of the number of Coherent RSUs earned, based on the greater of the target or actual level of achievement of such goals or metrics immediately prior to the Effective Time.

The converted Coherent RSUs generally will be subject to the same terms and conditions that applied to the awards immediately prior to the Effective Time, provided that any Coherent RSUs subject to performance-based vesting conditions will be subject solely to time- and service-based vesting. Each Coherent RSU that is outstanding as of the date of the Merger Agreement and as of immediately prior to the Effective Time will be entitled to the following vesting acceleration benefits:

(A) for any holder of Coherent RSUs who is a participant under Coherent’s Change of Control and Leadership Change Severance Plan (the “CIC Plan”), the acceleration benefits under the CIC Plan upon such participant’s involuntary termination of employment in accordance with the terms and conditions set forth therein; and

(B) for any holder who is not a participant in the CIC Plan, the following vesting acceleration benefits upon his or her termination of employment by Coherent, II-VI, or their respective subsidiaries without “cause” within the period beginning immediately following the date of the Closing and ending on the date that is 12 months following the date of the Closing (or, if earlier, December 31, 2022) (a “Qualifying Termination”), (1) if such holder’s Qualifying Termination occurs during calendar year 2021, the sum of: (x) 100% of the total number of converted Coherent RSUs that otherwise would have vested during calendar year 2021 under the applicable vesting schedule in effect on the Closing had such holder remained employed with Coherent, II-VI, or their respective subsidiaries through the last applicable vesting date for such award in calendar year 2021 (and reduced by the total number of converted Coherent RSUs that vested in calendar year 2021 prior to such Qualifying Termination) plus (y) 50% of the total number of converted Coherent RSUs that otherwise would have vested during calendar year 2022 under the applicable vesting schedule in effect on the Closing had such holder remained employed with Coherent, II-VI, or their respective subsidiaries through the last applicable vesting date for such award in calendar year 2022, or (2) if such holder’s Qualifying Termination occurs during calendar year 2022, 50% of the total number of converted Coherent RSUs that otherwise would have vested during calendar year 2022 under the applicable vesting schedule in effect on the Closing had such holder remained employed with Coherent, II-VI, or their respective subsidiaries through the last applicable vesting date for such award in calendar year 2022 (and reduced by the total number of converted Coherent RSUs that vested in calendar year 2022 prior to such Qualifying Termination).

Each Coherent RSU granted to a non-employee member of Coherent’s Board of Directors (“Director RSUs”) (whether or not vested) that is outstanding immediately prior to the Effective Time will automatically vest in full and be canceled and converted into the right to receive the Merger Consideration as if such Director RSU had been settled in shares of Coherent Common Stock immediately prior to the Effective Time.

The Boards of Directors of II-VI and Coherent unanimously approved the Merger and the Merger Agreement. II-VI filed with the SEC a registration statement on Form S-4 relating to the Merger, and the SEC declared that registration statement to be effective on May 6, 2021. Shareholders of II-VI and stockholders of Coherent voted to approve proposals related to the Merger at special meetings held on June 24, 2021 by the respective companies.

The completion of the Merger is subject to the satisfaction or waiver of certain additional customary closing conditions, including review and approval of the Merger by the State Administration for Market Regulation in China. Subject to the satisfaction or waiver of each of the closing conditions, II-VI expects that the Merger will be completed by year-end 2021 or at the beginning of the first calendar quarter of 2022. However, it is possible that factors outside the control of both companies could result in the Merger being completed at a different time or not at all.

Acquisitions

Acquisition of Ascatron AB

On August 20, 2020, the Company acquired all of the outstanding shares of Ascatron, located in Sweden. The acquisition will add essential elements to the Company's vertically integrated silicon carbide technology platform. Purchase price consideration totaled $37 million.

The Company utilized the widely accepted income-based approach (relief-from-royalty method) to perform the preliminary purchase price allocation.

The following table presents the final allocation of the purchase price of the assets acquired and liabilities assumed at the date of acquisitions ($000):

	Previously Reported September 30, 2020		Measurement Period Adjustments (a)		As Adjusted
Assets
Developed technology	$	20,000	$	(3,622)	$	16,378
Goodwill	18,922		3,018		21,940

Total liabilities assumed	(4,729)		(79)		(4,808)
Net assets acquired	$	36,704	$	—	$	36,704

(a) The Company recorded measurement period adjustments to its preliminary acquisition date fair values due to the refinement of its valuation models, assumptions and inputs. The measurement period adjustments were based upon information obtained about facts and circumstances that existed at the acquisition date that, if known, would have affected the measurement of the amounts recognized at that date.

The goodwill is recorded in the Compound Semiconductors segment and is attributed to the workforce acquired as part of the transaction. The goodwill is non-deductible for income tax purposes. Transaction expenses related to the acquisition totaled $2 million for the year ended June 30, 2021 and are included in Selling, General and Administrative expenses in the Consolidated Statements of Earnings (Loss). Technology is being amortized with a useful life of approximately 17 years.

The revenues and net loss from Ascatron included in the Company's Consolidated Statement of Earnings (Loss) for the year ended June 30, 2021 were $1 million and $3 million, respectively.

Certain data necessary to complete the purchase price allocation remains preliminary, including, but not limited to, finalization

of certain income tax computations and other assumed liabilities. The Company expects to complete the purchase price allocation within 12 months from the Closing Date, at which time the purchase price allocation set forth herein may be revised.

Purchase of Equity Investment in INNOViON Corporation

On October 1, 2020, II-VI acquired the remaining 6.1% interest in Innovion for $4 million. Innovion is a provider of ion implantation services supporting unique capabilities in semiconductor materials processing. This acquisition will add essential elements to the Company's vertically integrated silicon carbide technology platform.

Through the period ended December 31, 2020, the Company held a 93.9% investment in Innovion which was accounted for as an equity method investment. The Company accounted for the acquisition of the remaining equity of Innovion as a step acquisition, which required remeasurement of the Company's previous ownership interest to fair value prior to completing purchase accounting. Using step acquisition accounting the Company increased the value of its previously held equity investment to its fair value of $67 million, which resulted in a gain of approximately $7 million, recorded in other expense (income), net in the Consolidated Statements of Earnings (Loss) in the second quarter of fiscal year 2021.

The Company utilized widely accepted income-based, market-based, and cost-based valuation approaches to perform the preliminary purchase price allocation and determine the fair value of the previously held equity method investment. Income-based valuation approaches included the use of the multi-period excess earnings and relief-from-royalty methods for certain acquired intangible assets.

The following table presents the final allocation of the purchase price of the assets acquired and liabilities assumed at the date of acquisition ($000):

Senior Credit Facilities

The Company currently has Senior Credit Facilities with Bank of America, N.A., as Administrative Agent, Swing Line Lender and an L/C Issuer, and the other lenders party thereto.

The credit agreement governing the Senior Credit Facilities (the "Credit Agreement") provides for senior secured financing of $2.4 billion in the aggregate, consisting of

(i)Aggregate principal amount of $1,255 million for a five-year senior secured first-lien term A loan facility (the “Term A Facility”),

(ii)Aggregate principal amount of $720 million for a seven-year senior secured term B loan facility (the “Term B Facility” and together with the Term A Facility, the “Term Loan Facilities”), which was repaid in full during the quarter ended September 30, 2020, and

(iii)Aggregate principal amount of $450 million for a five-year senior secured first-lien revolving credit facility (the “Revolving Credit Facility” and together with the Term Loan Facilities, the “Senior Credit Facilities”).

The Credit Agreement also provides for a letter of credit sub-facility not to exceed $25 million and a swing loan sub-facility initially not to exceed $20 million.

The Term B Facility was repaid in full by the Company subsequent to the public offerings that closed on July 7, 2020. In conjunction with the repayment, the Company paid $1 million in associated interest and expensed $25 million of debt issuance costs related to the Term B Facility.

The Company is obligated to repay the outstanding principal amount of the Term A Facility in quarterly installments equal to 1.25% of the initial aggregate principal amount of the Term A Facility, with the remaining outstanding balance due and payable on the fifth anniversary of September 24, 2019 (the "Finisar Closing Date").

The Company’s obligations under the Senior Credit Facilities are guaranteed by each of the Company’s existing or future direct and indirect domestic subsidiaries (collectively, the “Guarantors”). Borrowings under the Senior Credit Facilities are collateralized by a first priority lien in substantially all of the assets of the Company and the Guarantors, except that no real property is collateral under the Senior Credit Facilities.

All amounts outstanding under the Senior Credit Facilities become due and payable 120 days prior to the maturity of the Company’s currently outstanding 0.25% Convertible Senior Notes due 2022 (the “II-VI Notes”) if (i) the II-VI Notes remain outstanding, and (ii) the Company has insufficient cash and borrowing availability to repay the principal amount of the II-VI Notes.

Amounts outstanding under the Senior Credit Facilities bear interest at a rate per annum equal to an applicable margin over a eurocurrency rate or an applicable margin over a base rate determined by reference to the highest of (a) the federal funds rate plus 0.50%, (b) Bank of America, N.A.’s prime rate and (c) a eurocurrency rate plus 1.00%, in each case as calculated in accordance with the terms of the Credit Agreement. The applicable interest rate would increase under certain circumstances relating to events of default.  The Company has entered into an interest rate swap contract to hedge its exposure to interest rate risk on its variable rate borrowings under the Senior Credit Facilities.  Refer to Note 15 for further information regarding this interest rate swap.

The Credit Agreement contains customary affirmative and negative covenants with respect to the Senior Credit Facilities, including limitations with respect to liens, investments, indebtedness, dividends, mergers and acquisitions, dispositions of assets and transactions with affiliates. The Company will be obligated to maintain a consolidated interest coverage ratio (as calculated in accordance with the terms of the Credit Agreement) as of the end of each fiscal quarter of not less than 3.00 to 1.00. The Company will be obligated to maintain a consolidated total net leverage ratio (as calculated in accordance with the terms of the Credit Agreement) of not greater than (i) 5.00 to 1.00 for the first four fiscal quarters after the Finisar Closing Date, commencing with the first full fiscal quarter after the Finisar Closing Date, (ii) 4.50 to 1.00 for the fifth fiscal quarter through and including the eighth fiscal quarter after the Finisar Closing Date, and (iii) 4.00 to 1.00 for each subsequent fiscal quarter. As of June 30, 2021, the Company was in compliance with all financial covenants under the Credit Agreement.

0.50% Finisar Convertible Notes

Finisar’s outstanding 0.50% Convertible Senior Notes due 2036 (the “Finisar Notes”) may be redeemed at any time on or after December 22, 2021 in whole or in part at the option of the Company at a redemption price equal to one hundred percent (100%) of the principal amount of such Finisar Notes plus accrued and unpaid interest. Each holder of Finisar Notes also may require Finisar to repurchase all or any portion of such holder’s outstanding Finisar Notes for cash on December 15, 2021, December 15, 2026 and December 15, 2031 at a repurchase price equal to one hundred percent ( 100%) of the principal amount of such Finisar Notes plus accrued and unpaid interest. The Finisar Notes will mature on December 15, 2036. Interest on the Finisar Notes accrues at 0.50% per annum, paid semi-annually, in arrears, on June 15 and December 15 of each year.

In connection with the acquisition of Finisar, the Company, Finisar and the trustee entered into a First Supplemental Indenture, dated as of September 24, 2019 (the “First Supplemental Indenture”). The First Supplemental Indenture supplements the base indenture (as supplemented, the “Finisar Indenture”), which governs the Finisar Notes. Pursuant to the terms of the First Supplemental Indenture, the Company has fully and unconditionally guaranteed, on a senior unsecured basis, the due and punctual payment and performance of all obligations of Finisar to the holders of the Finisar Notes. The First Supplemental Indenture also provides that the right of holders of Finisar Notes to convert Finisar Notes into cash and/or shares of Finisar’s common stock, is changed to a right to convert Finisar Notes into cash and shares of the Company’s common stock, subject to the terms of the Finisar Indenture.

0.25% Convertible Senior Notes

In August 2017, the Company issued and sold $345 million aggregate principal amount of the II-VI Notes in a private placement to qualified institutional buyers within the meaning of Rule 144A under the Securities Act of 1933, as amended.

As a result of our cash conversion option, the Company separately accounted for the value of the embedded conversion option as a debt discount, which was $58 million as of June 30, 2021. The value of the embedded conversion option was determined based on the estimated fair value of the debt without the conversion feature, which was determined using an expected present value technique (income approach) to estimate the fair value of similar nonconvertible debt; the debt discount is being amortized as additional non-cash interest expense over the term of the II-VI Notes using the effective interest method.

The equity component is not remeasured as long as it continues to meet the conditions for equity classification. The initial conversion rate is 21.25 shares of common stock per $1,000 principal amount of II-VI Notes, which is equivalent to an initial conversion price of $47.06 per share of II-VI common stock. Throughout the term of the II-VI Notes, the conversion rate may be adjusted upon the occurrence of certain events. The if-converted value of the II-VI Notes amounted to $532 million as of June 30, 2021 and $346 million as of June 30, 2020 (based on the Company’s closing stock price on the last trading day of the fiscal periods then ended).

Prior to the close of business on the business day immediately preceding June 1, 2022, the Notes will be convertible only under the following circumstances:

(i) during any fiscal quarter commencing after the fiscal quarter ending on December 31, 2017 (and only during such fiscal quarter), if the last reported sale price of the II-VI Common Stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

(ii) during the five business day period immediately after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the II-VI Common Stock and the conversion rate on each such trading day; or

(iii) upon the occurrence of certain specified corporate events.

On or after June 1, 2022 until the close of business on the business day immediately preceding the maturity date, holders may convert their Notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of II-VI Common Stock or a combination of cash and shares of II-VI Common Stock, at the Company’s election.

Because the last reported sale price of II-VI Common Stock for at least 20 trading days during the period of 30 consecutive trading days ending on the last trading day of the calendar quarter ended June 30, 2021 was equal to or greater than 130% of the applicable conversion price on each applicable trading day, the II-VI Notes are convertible at the option of the holders thereof during the fiscal quarter ending September 30, 2021.

Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of II-VI Common Stock or a combination of cash and shares of II-VI Common Stock, at the Company’s election.

Holders of the II-VI Notes will not receive any cash payment representing accrued and unpaid interest upon conversion of a II-VI Note. Accrued but unpaid interest will be deemed to be paid in full upon conversion rather than cancelled, extinguished or forfeited. II-VI Notes were convertible during the quarters ended March 31, and June 30, 2021; conversions were immaterial.

The following table sets forth total interest expense recognized related to the II-VI Notes for the years ended June 30, 2021, 2020 and 2019 ($000):

On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was signed into law. The Tax Act includes changes to the U.S. statutory federal tax rate and puts into effect the migration from a worldwide system of taxation to a territorial system, among other things. The Tax Act includes certain changes such as introducing a new category of income, referred to as global intangible low tax income (“GILTI”), related to earnings taxed at a low rate of foreign entities without a significant fixed asset base, and imposes additional limitations on the deductibility of interest and officer compensation. The Company made a final accounting policy election to treat taxes due from future inclusions in U.S. taxable income related to GILTI as a current period expense when incurred.

The Company previously considered the earnings in non-U.S. subsidiaries to be indefinitely reinvested and, accordingly, recorded no deferred income taxes.  As a result of the Act, among other things, the Company determined it 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 $22 million.

During the fiscal years ended June 30, 2021, 2020, and 2019, net cash paid by the Company for income taxes was $60 million, $40 million, and $26 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 3.22%, (8.91)% and 0.25% for the fiscal years ended June 30, 2021, 2020 and 2019, respectively, and the impact of the tax holidays on diluted earnings per share is $0.10, $0.07, and $0.00 for the fiscal years ended June 30, 2021, 2020, and 2019, respectively. The holiday related to II-VI Malaysia Advanced Manufacturing Center Sdn. Bhd will end during the fiscal year ended June 30, 2026, the holiday related to certain II-VI Laser Enterprise Philippines, Inc.'s business lines will end during the fiscal year ended June 30, 2022, and the holiday related to II-VI Vietnam Co., Ltd will end during the fiscal year ended June 30, 2024.

The Company has the following gross operating loss carryforwards and tax credit carryforwards as of June 30, 2021:

Type	Amount		Expiration Date
($000)
Tax credit carryforwards:
Federal research and development credits	$	79,211	June 2022-June 2041
Foreign tax credits	20,493		June 2022-June 2031
State tax credits	15,434		June 2022-June 2036
State tax credits (indefinite)	39,125		Indefinite
Operating loss carryforwards:
Loss carryforwards - federal	$	47,755	June 2022-June 2036
Loss carryforwards - state	136,454		June 2022-June 2041
Loss carryforwards - state (indefinite)	13,076		Indefinite
Loss carryforwards - foreign	17,375		June 2021-June 2040
Loss carryforwards - foreign (indefinite)	48,884		Indefinite

The Company has recorded a valuation allowance against the majority of the foreign and state loss and credit carryforwards. The Company’s U.S. federal loss carryforwards, federal research and development credit carryforwards, 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, 2021, 2020 and 2019 were as follows:

	2021		2020		2019
($000)
Beginning balance	$	42,803	$	11,520	$	9,892
Increases in current year tax positions	3,940		1,506		191
Increases in prior year tax positions	—		—		376
Acquired business	5,341		31,791		6,036
Settlements	(7,514)		—		—
Expiration of statute of limitations	(6,545)		(2,014)		(4,975)
Ending balance	$	38,025	$	42,803	$	11,520

The Company classifies all estimated and actual interest and penalties as income tax expense. During fiscal years 2021, 2020 and 2019, there was $0.3 million, $0.6 million and $(0.1) million of interest and penalties within income tax expense, respectively. The Company had $3 million, $4 million and $1 million of interest and penalties accrued at June 30, 2021, 2020 and 2019, 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. 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 $26 million, $24 million and $6 million at June 30, 2021, 2020 and 2019, respectively. The Company expects a decrease of $2 million of unrecognized tax benefits during the next 12 months due to the expiration of statutes of limitation.

Fiscal years 2018 to 2021 remain open to examination by the Internal Revenue Service, fiscal years 2016 to 2021 remain open to examination by certain state jurisdictions, and fiscal years 2010 to 2021 remain open to examination by certain foreign taxing jurisdictions. The Company is currently under examination in New York for the years ended June 30, 2018 though June 30, 2019 and under examination for certain subsidiary companies in India for the year ended March 31, 2016; Philippines for the year ended June 30, 2019; and Germany for the years ended June 30, 2012 through June 30, 2018. The Company believes its income tax reserves for these tax matters are adequate.

Equity [Abstract]

Equity and Redeemable Preferred Stock

Equity and Redeemable Preferred Stock

Mandatory Convertible Preferred Stock

On July 2, 2020, II-VI announced the pricing of an underwritten public offering of 2,000,000 shares of 6.00% Series A Mandatory Convertible Preferred, no par value per share (“Mandatory Convertible Preferred Stock”), resulting in gross proceeds to II-VI from the offering of $400 million, before deducting the underwriting discounts and commissions and offering expenses payable by the Company (the “Preferred Stock Offering”). In addition, the underwriters had a 30-day option to purchase up to an additional 300,000 shares of Series A Mandatory Convertible Preferred Stock at the applicable public offering price, less underwriting discounts and commissions and solely to cover over-allotments with respect to the preferred stock offering. On July 2, 2020, the underwriters exercised the option in full, raising an additional approximately $60 million in gross proceeds. On July 7, 2020, the Company closed the Preferred Stock Offering, including the issuance and sale of 2 million shares of Mandatory Convertible Preferred Stock.

Upon conversion on the mandatory conversion date, July 1, 2023, as determined in accordance with the terms of the Mandatory Convertible Preferred Stock, each outstanding share of the Mandatory Convertible Preferred Stock, unless previously converted, will automatically convert into a number of shares of II-VI Common Stock equal to not more than 4.6512 shares of II-VI Common Stock and not less than 3.8760 shares of II-VI Common Stock (the “Minimum Conversion Rate”), depending on the applicable market value of the II-VI Common Stock, determined in accordance with the terms of the Mandatory Convertible Preferred Stock and subject to certain anti-dilution adjustments.

Other than in the event of one of certain fundamental changes, a holder of Mandatory Convertible Preferred Stock may, at any time prior to July 1, 2023, elect to convert such holder’s shares of Mandatory Convertible Preferred Stock, in whole or in part (but in no event less than one share of Mandatory Convertible Preferred Stock), at the Minimum Conversion Rate per share of Mandatory Convertible Preferred Stock, subject to certain anti-dilution adjustments.

If one of certain fundamental changes occurs on or prior to July 1, 2023, holders of the Mandatory Convertible Preferred Stock will have the right to convert their shares of Mandatory Convertible Preferred Stock, in whole or in part (but in no event less than one share of the Mandatory Convertible Preferred Stock), into shares of II-VI Common Stock at the conversion rate determined in accordance with the terms of the Mandatory Convertible Preferred Stock during the period beginning on, and including, the effective date of such change and ending on, and including, the date that is 20 calendar days after the effective date of such fundamental change (or, if later, the date that is 20 calendar days after holders receive notice of such fundamental change, but in no event later than July 1, 2023). Holders who convert their shares of the Mandatory Convertible Preferred Stock during that period will also receive a dividend make-whole amount and, to the extent there is any, the accumulated dividend amount, in each case as calculated in accordance with the terms of the Mandatory Convertible Preferred Stock.

Upon issuance of the Mandatory Convertible Preferred Stock, the Company used a Monte Carlo simulation model to estimate the future market value of the II-VI Common Stock on the mandatory conversion date, based on the following inputs:

Expected Volatility	50% - 55%
Cost of Equity	14% - 17%
Dividend Yield	none

Expected volatility is based on the historical volatility of II-VI Common Stock, taking into consideration the mean-reverting tendency of volatility and the expected term of the Mandatory Convertible Preferred Stock, as well as traded option contracts for II-VI Common Stock. The cost of equity was calculated over a three-year term, assuming a risk-free interest rate of 0.2% derived from the average U.S. Treasury Note rate during the period. The dividend yield of zero is based on the fact that the Company has never paid cash dividends on II-VI Common Stock and has no current intention to pay cash dividends on II-VI Common Stock in the future.

The Company declared $27 million of preferred stock dividends during fiscal year 2021 associated with the Mandatory Convertible Preferred Stock. Dividends from the quarter ended June 30, 2021 were $7 million and were presented as other accrued liabilities on the Consolidated Balance Sheet.

The following table presents dividends per share and dividends recognized for the year ended June 30, 2021:

	Year Ended June 30, 2021
Dividends per share	11.80
Series A Mandatory Convertible Preferred Stock dividends ($000)	27,140

Redeemable Convertible Preferred Stock

The Company issued 75,000 shares of II-VI Series B-1 Convertible Preferred Stock in the year ended June 30, 2021. Refer to Note 3. Pending Coherent Acquisition for additional information.

In connection with the execution of the Investment Agreement, on March 30, 2021, the Company filed a Statement with Respect to Shares (the “Statement”) with the Pennsylvania Department of State Corporation Bureau to establish the designation, rights and preferences of the II-VI Series B-1 Convertible Preferred Stock. The Statement became effective on March 30, 2021.

The shares of II-VI Series B-1 Convertible Preferred Stock accrue dividends at 5.00% per annum, subject to increase if II-VI defaults on payment obligations with respect to the New II-VI Convertible Preferred Stock, not to exceed 14% per annum. Until the fourth anniversary of March 31, 2021 (the “Initial Issue Date”), dividends are payable solely in-kind. After the fourth anniversary of the Initial Issue Date, dividends are payable on the applicable series, at the Company’s option, in cash, in-kind, or as a combination of both.

The shares of II-VI Series B-1 Convertible Preferred Stock are convertible into shares of II-VI Common Stock as follows:

•at any time after their issuance, at the election of the holder, each share of II-VI Series B-1 Convertible Preferred Stock may be converted into shares of II-VI Common Stock at a conversion price of $85.00 per share (“Conversion Price”), except that the shares of II-VI Series B-1 Convertible Preferred Stock will be so convertible only after the earliest to occur of (i) the issuance of shares of II-VI Series B-2 Convertible Preferred Stock upon the Closing, (ii) the termination of the Merger Agreement or (iii) the delivery by II-VI to the Investor of an offer to repurchase the II-VI Series B-1 Convertible Preferred Stock upon the occurrence of a Fundamental Change (as defined in the Statement); and

•at any time following the third anniversary of Initial Issue Date, at the election of II-VI, each share of II-VI Series B-1 Convertible Preferred Stock may be converted into shares of II-VI Common Stock at the then-applicable Conversion Price if the volume-weighted average price of II-VI Common Stock exceeds 150% of the then- applicable Conversion Price for 20 trading days out of any 30 consecutive trading days.

The II-VI Series B-1 Convertible Preferred Stock have voting rights, voting as one class with the II-VI Common Stock, on an as-converted basis, subject to limited exceptions.

On or at any time after the tenth anniversary of the Initial Issue Date:

•each holder has the right to require the Company to redeem all of their II-VI Series B-1 Convertible Preferred Stock, for cash, at a redemption price per share equal to the sum of the Stated Value for such shares (as defined in the Statement) 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 II-VI Series B-1 Convertible Preferred Stock outstanding, for cash, at the Redemption Price.

In connection with any Fundamental Change, and subject to the procedures set forth in the Statement, the Company must, or will cause the survivor of a Fundamental Change (such survivor of a Fundamental Change, the “Acquirer”) to, make an offer to repurchase, at the option and election of the holder thereof, each share of II-VI Series B-1 Convertible Preferred Stock then-outstanding (the “Fundamental Change Repurchase Offer”) 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 the fifth anniversary of the Initial Issue Date, the aggregate amount of all dividends that would have been paid (subject to certain exceptions), from the date of repurchase through the fifth anniversary of the Initial Issue Date.

The II-VI Series B-1 Convertible Preferred Stock is redeemable for cash outside of the control of the Company upon the exercise of the Put Rights, and upon a Fundamental Change, and is therefore classified as mezzanine equity.

The Company recognized $10 million of preferred stock dividends during the fiscal year ended 2021, which were presented as a reduction to retained earnings on the Consolidated Balance Sheet as of June 30, 2021. The Company incurred $27 million of transaction costs associated with the II-VI Series B-1 Convertible Preferred Stock, of which, $23 million were capitalized, and $4 million were expensed in the Selling, General, and Administrative expenses in the Consolidated Statements of Earnings (Loss) for the fiscal year ended June 30, 2021.

	Year Ended June 30, 2021
Dividends per share	$	134.55
Dividends ($000)	9,583

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

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

The diluted earnings (loss) per common share is computed by dividing the diluted earnings (loss) available to 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 method. For the fiscal years ended 2021, 2020 and 2019, diluted shares outstanding include the

dilutive effect of the potential shares of the Company's common stock issuable from stock options, performance and restricted shares. For fiscal year ended 2021, the diluted shares outstanding also include the dilutive effect of the potential shares of the Company's Common Stock issuable upon conversion of outstanding convertible debt

The following is a reconciliation of the numerators and denominators of the basis and diluted earnings (loss) per share computations for the periods presented ($000):

Leases [Abstract]

Leases

Leases

We determine if an arrangement is a lease at inception and classify it as either finance or operating.

Finance leases are generally those that allow us to substantially utilize or pay for the entire asset over its estimated useful life. Finance leases are recorded in property, plant and equipment, net, and finance lease liabilities within other current and other non-current liabilities on our Consolidated Balance Sheet. 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 the Company’s Consolidated Balance Sheet. Operating lease assets are amortized on a straight-line basis in operating expenses over the lease term.

The Company’s 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. The Company’s 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.

The Company’s 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 short-term leases, lease term, and discount rates ($000):

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 the Company’s Consolidated Balance Sheet. Operating lease assets are amortized on a straight-line basis in operating expenses over the lease term.

The Company’s 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. The Company’s 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.

The Company’s 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 short-term leases, lease term, and discount rates ($000):

Share-based Payment Arrangement [Abstract]

Shared-Based Compensation

Share-Based Compensation

The Company’s Board of Directors amended the II-VI Incorporated 2018 Omnibus Incentive Plan, which was approved by the shareholders at the Annual Meeting in November 2018. The Amended Omnibus Plan (the “Plan”) was approved at the annual meeting in November 2020. The Plan provides for the grant of non-qualified stock options, stock appreciation rights, restricted shares, restricted share units, deferred shares, performance shares and performance share units to employees, officers and directors of the Company. The maximum number of shares of the Company’s common stock authorized for issuance under the Plan is limited to 9,550,000 shares of common stock, not including any remaining shares forfeited under the predecessor plans that may be rolled into the Plan. The Plan has vesting provisions predicated upon the death, retirement or disability of the grantee.

As of June 30, 2021, there were approximately 8 million shares available to be issued under the Plan, including forfeited shares from predecessor plans.

The Company records share-based compensation expense for these awards, which requires the recognition of the grant-date fair value of share-based compensation in net earnings. The Company recognizes the share-based compensation expense over the requisite service period of the individual grantees, which generally equals the vesting period. The Company accounts for cash-based stock appreciation rights, cash-based restricted share units and cash-based performance share units as liability awards, in accordance with U.S. GAAP.

Share-based compensation expense for the fiscal years ended June 30, 2021, 2020 and 2019 is as follows $000:

Year Ended June 30,	2021		2020		2019
Stock Options and Cash-Based Stock    Appreciation Rights	$	10,626	$	11,893	$	6,801
Restricted Share Awards, Restricted Share    Units, and Cash-Based Restricted Share Units	47,060		49,957		9,242
Performance Share Units and Cash    Based Performance Share Units	16,640		11,977		8,920
	$	74,326	$	73,827	$	24,963

Stock Options and Cash-Based Stock Appreciation Rights:

The Company utilized the Black-Scholes valuation model for estimating the fair value of stock options and cash-based stock appreciation rights. During the fiscal year ended June 30, 2021, no stock options were issued. During fiscal years ended June 30, 2020 and 2019, the weighted-average fair value of options granted under the Plan was $14.79 and $20.66, respectively, per option using the following assumptions:

Year Ended June 30,	2020		2019
Risk-free interest rate	1.50	%	2.80	%
Expected volatility	39	%	37	%
Expected life of options	6.91 years		6.96 years
Dividend yield	None		None

The risk-free interest rate is derived from the average U.S. Treasury Note rate during the period, which approximates the rate in effect at the time of grant related to the expected life of the options. The risk-free interest rate shown above is the weighted average rate for all options granted during the fiscal year. Expected volatility is based on the historical volatility of the Company’s common stock over the period commensurate with the expected life of the options. The expected life calculation is based on the observed time to post-vesting exercise and/or forfeitures of options by our employees. The dividend yield of zero is based on the fact that the Company has never paid cash dividends and has no current intention to pay cash dividends in the future.

Stock option and cash-based stock appreciation rights activity during the fiscal year ended June 30, 2021 was as follows:

	Stock Options			Cash-Based Stock Appreciation Rights
	Number of Shares	Weighted Average Exercise Price		Number of Rights	Weighted Average Exercise Price
Outstanding - July 1, 2020	3,721,801	$	26.99	230,374	$	32.13
Exercised	(1,047,216)	$	21.04	(76,880)	$	28.75
Forfeited and Expired	(31,951)	$	33.86	(8,160)	$	34.14
Outstanding - June 30, 2021	2,642,634	$	29.26	145,334	$	33.80
Exercisable - June 30, 2021	1,805,735	$	25.31	63,209	$	27.36

As of June 30, 2021, 2020 and 2019, the aggregate intrinsic value of stock options and cash-based stock appreciation rights outstanding and exercisable was $88 million, $80 million and $56 million, respectively. Aggregate intrinsic value represents the total pretax intrinsic value (the difference between the Company’s 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, 2021. 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, 2021, 2020, and 2019 was $49 million, $20 million, and $15 million, respectively. As of June 30, 2021, total unrecognized compensation cost related to non-vested stock options and cash-based stock appreciation rights was $9 million. This cost is expected to be recognized over a weighted-average period of approximately two years.

Outstanding and exercisable stock options at June 30, 2021 were as follows:

	Stock Options and Cash-Based Stock Appreciation Rights Outstanding				Stock Options and Cash-Based Stock Appreciation Rights Exercisable
	Number of	Weighted Average Remaining	Weighted Average		Number of	Weighted Average Remaining	Weighted Average
Range of	Shares or	Contractual Term	Exercise		Shares or	Contractual Term	Exercise

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.

Restricted share award, restricted share unit, and cash-based restricted share unit activity during the fiscal year ended June 30, 2021, was as follows:

	Restricted Share Awards			Restricted Share Units			Cash-Based Restricted Share Units
	Number of Shares	Weighted Average Grant Date  Fair Value		Number of Units	Weighted Average Grant Date Fair Value		Number of Units	Weighted Average Grant Date Fair Value
Nonvested - June 30, 2020	50,527	$	35.92	2,242,412	$	39.46	82,003	$	38.31
Granted	—	$	—	1,277,460	$	45.74	5,194	$	44.30
Vested	(49,525)	$	35.47	(996,955)	$	37.91	(38,943)	$	38.57
Forfeited	(1,002)	$	18.42	(196,745)	$	38.36	(2,381)	$	38.91
Nonvested - June 30, 2021	—	$	—	2,326,172	$	43.67	45,873	$	38.75

As of June 30, 2021, total unrecognized compensation cost related to non-vested, restricted share unit and cash-based restricted share units was $68 million. This cost is expected to be recognized over a weighted-average period of approximately two years. The restricted share award and 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, 2021, 2020 and 2019, was $59 million, $11 million and $10 million, respectively. The total fair value of restricted share awards, restricted share units and cash-based restricted share units vested was $69 million, $75 million and $20 million during fiscal years 2021, 2020 and 2019, respectively.

Performance Share Units and Cash-Based Performance Share Units:

The Compensation Committee of the Board of Directors of the Company has granted certain executive officers and employees performance share units and cash-based performance share units under the Plan. As of June 30, 2021, the Company 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. The cash-based performance 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. Performance share unit and cash-based performance share unit activity relating to the Plan during the year ended June 30, 2021, was as follows:

	Performance Share Units			Cash-Based Performance Share Units
	Number of Units	Weighted Average Grant Date Fair Value		Number of Units	Weighted Average Grant Date Fair Value
Nonvested - June 30, 2020	409,246	$	40.96	35,188	$	38.54
Granted	209,639	$	52.04	—	$	—
Vested	(187,410)	$	30.03	(14,928)	$	35.25
Forfeited	(5,344)	$	37.66	—	$	—
Performance Adjustments	92,178	$	17.52	7,464	$	35.25
Nonvested - June 30, 2021	518,309	$	45.28	27,724	$	39.43

As of June 30, 2021, total unrecognized compensation cost related to non-vested performance share units and cash-based performance share units was $12 million. This cost is expected to be recognized over a weighted-average period of approximately 1.65 years. The total fair value of the performance share units and cash-based performance share units granted during the fiscal years ended June 30, 2021, 2020 and 2019 was $14 million, $15 million and $10 million, respectively. The total fair value of performance share units and cash-based performance share units vested during the fiscal years ended June 30, 2021, 2020 and 2019 was $9 million, $6 million and $11 million, respectively. The performance adjustments relate to grants that exceeded the performance targets when vested during FY21, including the final number of shares issued, which were 200% of the target units based on actual results during the three-year performance period.

Segment Reporting [Abstract]

Segment and Geographic Reporting

Segment and Geographic Reporting

The Company reports its business segments using the “management approach” model for segment reporting. This means that the Company determines its reportable business segments based on the way the chief operating decision maker organizes business segments within the Company for making operating decisions and assessing performance.

The Company reports its financial results in two segments, and the Company’s chief operating decision maker receives and reviews financial information based on these segments.  The Company evaluates business segment performance based upon segment operating income, which is defined as earnings before income taxes, interest and other income or expense.

The Compound Semiconductors segment has locations in the United States, Singapore, China, Germany, Switzerland, Japan, Belgium, the United Kingdom, Italy, South Korea, the Philippines, Vietnam, Sweden, and Taiwan. This segment address all of II-VI's seven end markets, namely: communications, industrial, aerospace & defense, consumer electronics, semiconductor capital equipment, life sciences and automotive. This segment designs, manufactures and markets the following products: (i) optical and electro-optical components and materials used primarily in CO2 lasers, fiber-lasers and direct diode lasers for materials processing applications; (ii) infrared optical components and high-precision optical assemblies for aerospace and defense, medical and commercial laser imaging applications; (iii) semiconductor lasers and detectors for optical interconnects and sensing applications; (iv) engineered materials for thermoelectric, ceramics and silicon carbide for a wide range of applications; and (v) compound semiconductor epitaxial wafers for applications in optical and wireless communication.

The Photonic Solutions segment has locations in the United States, China, Vietnam, Germany, Japan, the United Kingdom, Italy, Malaysia, Australia, and Hong Kong. This segment manufactures (i) transceivers for data centers and telecom optical networks; (ii) pump lasers, optical amplifiers, wavelength selective switches and advanced components for telecom networks; (iii) crystal materials, optics, lasers and optoelectronic modules for a wide range of applications, including in optical communications, life sciences, and consumer electronics markets.

In September 2019, the Company completed its acquisition of Finisar. The operating results of this acquisition have been reflected in the selected financial information of the Company’s Photonic Solutions segment and Compound Semiconductors Segment beginning on October 1, 2019, with the results from September 24, 2019 to September 30, 2019 reflected in Unallocated and Other.

The accounting policies are consistent across both of the segments. To the extent possible, the Company’s corporate expenses are allocated to the segments. The Company evaluates segment performance based upon reported segment operating income, which is defined as earnings from continuing operations before income taxes, interest and other income or expense. Unallocated and Other include eliminating inter-segment sales and transfers as well as transaction costs related to the pending Coherent

acquisition in the fiscal year ended June 30, 2021. In the fiscal year ended June 30, 2020, it included transaction costs related to the Finisar acquisition.

Fair Value of Financial Instruments

12 Months Ended

Jun. 30, 2021

Business Combinations [Abstract]

Fair Value of Financial Instruments

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. The Company estimates fair value of its 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.

The Company entered into an interest rate swap with a notional amount of $1,075 million to limit the exposure to its variable interest rate debt by effectively converting it to a fixed interest rate. The Company receives payments based on the one-month LIBOR and makes payments based on a fixed rate of 1.52%. The Company receives payments with a floor of 0.00%. The interest rate swap agreement has an effective date of November 24, 2019, with an expiration date of September 24, 2024. The initial notional amount of the interest rate swap is scheduled to decrease to $825 million in June 2022 and will remain at that amount through the expiration date. The Company designated this instrument as a cash flow hedge and deemed the hedge relationship effective at inception of the contract. The fair value of the interest rate swap of $29 million is recognized in the Consolidated Balance Sheet within other accrued liabilities (current) and other liabilities (non-current). Changes in fair value are recorded within accumulated other comprehensive income (loss) on the Consolidated Balance Sheet and reclassified into the Consolidated Statements of Earnings (Loss) as interest expense in the period in which the underlying transaction affects earnings. Cash flows from hedging activities are reported in the Consolidated Statements of Cash Flows in the same classification as the hedged item, generally as a component of cash flows from operations. The fair value of the interest rate swap is determined using widely accepted valuation techniques and reflects the contractual terms of the interest rate swap 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 interest rate swap is classified as a Level 2 item within the fair value hierarchy.

The Company estimated the fair value of the II-VI Notes and Finisar Notes based on quoted market prices as of the last trading day prior to June 30, 2021; however, the II-VI Notes and Finisar Notes have only a limited trading volume and as such this fair value estimate is not necessarily the value at which the II-VI Notes and Finisar Notes could be retired or transferred. The Company concluded that this fair value measurement should be categorized within Level 2. The carrying value of the II-VI Notes and Finisar Notes is net of unamortized discount and issuance costs. See Note 9. Debt for details on the Company’s debt facilities.

The fair value and carrying value of the II-VI Notes and Finisar Notes were as follows at June 30, 2021 ($000):

	Fair Value		Carrying Value
II-VI Notes	$	549,580	$	328,032
Finisar Notes	$	14,889	$	14,888

The fair values of 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. The Company’s borrowings including its lease obligations, excluding the 0.25% Convertible Notes and the 0.50% Finisar convertible notes, are considered Level 2 among the fair value hierarchy and their principal amounts approximate fair value.

By entering into the Investment Agreement as described in Note 3 on March 25, 2021, the Company entered into a commitment to issue shares of II-VI Series B-1 Convertible Preferred Stock on the Initial Closing Date for a fixed price (such commitment the "Forward Sale Commitment"). The Forward Sale Commitment comprises a financial instrument, other than an outstanding share, that, at inception, has both of the following characteristics: (i) embodies an obligation to repurchase the Company's equity shares and (ii) requires or may require the Company to settle the obligation by transferring assets. Under ASC 480, Distinguishing Liabilities from Equity, it is required to be initially measured and subsequently remeasured, at fair value as an asset or liability with changes in fair value recognized in earnings. An option pricing model was utilized to calculate the fair value of the Forward Sale Commitment. The Company recognized $11 million of realized gains within Other Expense (Income), Net in the Consolidated Statements of Earnings (Loss) for the year ended June 30, 2021, related to the Forward Sale Commitment due to changes in its fair value from March 25, 2021 to its settlement on March 31, 2021.

The Company, from time to time, purchases foreign currency forward exchange contracts, that permit it to sell specified amounts of these foreign currencies expected to be received from its export sales, for pre-established U.S. dollar amounts at specified dates. These contracts are entered into to limit transactional exposure to changes in currency exchange rates of export sales transactions in which settlement will occur in future periods and which otherwise would expose the Company, on the basis of its aggregate net cash flows in respective currencies, to foreign currency risk.

Employee Benefit Plans

Employee Benefit Plans

Eligible U.S. employees of the Company participate in a profit sharing retirement plan. Contributions accrued for the plan are made at the discretion of the Company’s board of directors and were $2 million, $6 million, and $5 million for the years ended June 30, 2021, 2020 and 2019, respectively.

On August 18, 2018, the Company adopted the 2018 Employee Stock Purchase Plan (“2018 Plan”) for full time U.S. employees who have completed two years of continuous employment with the Company, and the 2018 Plan was approved by the Company’s shareholders at the Company’s Annual Meeting of Shareholders in November 2018. The employee may purchase the Company’s common stock for the lesser of 90% of the fair market value of the shares (i) on the first trading day of the offering period, or (ii) on the purchase date. Offering periods will run from August through January and from February through July each year. The number of shares which may be bought by an employee during each fiscal year is limited to 15% of the employee’s base pay. The 2018 Plan limits the number of shares of common stock available for purchase to 2,000,000 shares. As of June 30, 2021, there have been 361,834 shares purchased on behalf of the employees under the 2018 Plan.

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 for years ended June 30, 2021 and 2020 were $4 million and $3 million, respectively. Net periodic pension cost is not material for any year presented.

The underfunded pension liability was $25 million and $27 million as of June 30, 2021 and 2020, respectively. The pension adjustment amount recognized in accumulated other comprehensive income was $2 million decrease and $3 million increase for the fiscal years ended June 30, 2021 and 2020, respectively. The accumulated benefit obligation was $90 million as of June 30, 2021, compared to $85 million as of June 30, 2020.

Estimated future benefit payments under the Swiss Plan are estimated to be as follows:

Year Ending June 30,

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and ContingenciesThe Company has 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 the Company’s materials and processes, certain contracts may contain liquidated damage provisions for early termination. The Company does 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. The Company also has contingent obligations relating to earnout arrangements on its acquisitions of $1 million. Total future purchase commitments held by II-VI as of June 30, 2021, were $352 million in fiscal 2022, and $35 million thereafter.

Share Repurchase Programs

In August 2014, the Company’s Board of Directors authorized the Company to purchase up to $50 million of its common stock through a share repurchase program (the “Program”) that calls for shares to be purchased in the open market or in private transactions from time to time. The Program has no expiration and may be suspended or discontinued at any time. Shares purchased by the Company are retained as treasury stock and available for general corporate purposes. The Company did not repurchase any shares pursuant to this Program during the fiscal year ended June 30, 2021. During the fiscal

year ended June 30, 2020 the Company purchased 50,000 shares of its common stock for $2 million

under this program. As of June 30, 2021, the Company has cumulatively purchased 1,416,587 shares of II-VI common stock pursuant to the Program for approximately $22 million.

Nature of Business and Summary of Significant Accounting Policies (Policies)

12 Months Ended

Jun. 30, 2021

Accounting Policies [Abstract]

Principles of Consolidation

Principles of Consolidation. The Consolidated Financial Statements include the accounts of the Company. All intercompany transactions and balances have been eliminated.

Estimates

Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Foreign Currency Translation

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 and Cash Equivalents

Cash and Cash Equivalents. The Company considers highly liquid investment instruments with an original maturity of three months or less to be cash equivalents. We place our cash and cash equivalents with high credit quality financial institutions and to date have not experienced credit losses in these instruments.

Accounts Receivable

Accounts Receivable. The Company makes estimates evaluating its allowance for doubtful accounts. The Company continuously monitors collections and payments from its customers and maintains a provision for estimated credit losses based upon its historical experience, current market conditions and any specific customer collection issues that it has identified.

Inventories

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, if applicable, other factors, including known trends, market conditions, currency exchange rates and other such issues. The Company generally records 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. 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. The Company reviews its 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 20 years and 3 to 20 years for machinery and equipment.

Leases

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 the Company's right to use an underlying asset for the lease term, and lease liabilities represent the Company's 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. The Company uses 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. The Company has 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 13 for additional information

Business Combinations

Business Combinations. The Company accounts for business acquisitions 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.

On August 20, 2020, the Company acquired all of the outstanding shares of Ascatron AB ("Ascatron"), located in Sweden and on October 1, 2020, the Company acquired the remaining 6.1% interest in INNOViON Corporation ("Innovion"). Refer to Note 4 Acquisitions for further information regarding the Innovion and Ascatron acquisitions.

Goodwill

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. The Company tests 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 the Company’s reporting units to the recorded value (including goodwill). The Company uses a discounted cash flow (“DCF”) model and/or a market analysis to determine the fair value of its 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.

The Company has the option to perform a qualitative assessment of goodwill prior to completing the quantitative assessment described above to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill and other intangible assets. If the Company concludes that this is the case, it must perform the quantitative assessment. Otherwise, the Company will forego the quantitative assessment and does not need to perform any further testing. As of April 1 of fiscal years 2021 and 2020, the Company completed its annual impairment tests of its reporting units using the quantitative assessment. Based on the results of these analyses the Company’s goodwill was not impaired.

Intangibles

Intangibles. Intangible assets are initially recorded at their cost or fair value upon acquisition. Finite-lived intangible assets are amortized for financial reporting purposes using the straight-line method over the estimated useful lives of the assets ranging from 3 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.

Investments in Other Entities

Investments in Other Entities. In the normal course of business, the Company enters into various types of investment arrangements, each having unique terms and conditions. These investments may include equity interests held by the Company in business entities, including general or limited partnerships, contractual ventures, or other forms of equity participation. The Company determines whether such investments involve a variable interest entity (“VIE”) based on the characteristics of the subject entity. If the entity is determined to be a VIE, then management determines if the Company is the primary beneficiary of the entity and whether or not consolidation of the VIE is required. The primary beneficiary consolidating the VIE must normally have both (i) the power to direct the activities of a VIE that most significantly affect the VIE’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE, in either case that could potentially be significant to the VIE. When the Company is deemed to be the primary beneficiary, the VIE is consolidated and the other party’s equity interest in the VIE is accounted for as a noncontrolling interest.

The Company generally accounts for investments it makes in VIEs in which it has determined that it does not have a controlling financial interest but has significant influence over or holds at least a 20% ownership interest using the equity method. Any such investment not meeting the parameters to be accounted under the equity method would be accounted for under ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. If an entity fails to meet the characteristics of a VIE, management then evaluates such entity under the voting model. Under the voting model, management consolidates the entity if they determine that the Company, directly or indirectly, has greater than 50% of the voting shares and determines that other equity holders do not have substantive participating rights.

Series A Mandatory Convertible Preferred Stock and Series B Convertible Preferred Stock

Series A Mandatory Convertible Preferred Stock. The II-VI Series A Mandatory Convertible Preferred Stock is initially measured at fair value, less underwriting discounts and commissions and offering expenses paid by the Company. The Preferred Stock’s dividends are cumulative, at 6% per annum. Series B Convertible Preferred Stock. The II-VI Series B-1 Convertible Preferred Stock is 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 Available to the Common Shareholder.

Commitments and Contingencies

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. Legal costs incurred in connection with loss contingencies are expensed as incurred. Such accruals 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. The Company had no material loss contingency liabilities at June 30, 2021 related to commitments and contingencies.

Income Taxes

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.

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.

Revenue Recognition

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 the Company’s customer have been satisfied and control has transferred to the customer. The Company has elected the practical expedient to exclude all taxes from the measurement of the transaction price.

For contracts with commercial customers, which comprise the majority of the Company’s performance obligations, ownership of the goods and associated revenue are transferred to customers at a point in time, generally upon shipment of a product to the

customer or receipt of the product by 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.

Contracts with the U.S. government through its prime contractors are typically for products or services with no alternative future use to the Company with an enforceable right to payment for performance completed to date, whereas commercial contracts typically have alternative use. Customized products with no alternative future use to the Company with an enforceable right to payment for performance completed to date are recorded over time utilizing the output method of units delivered. The Company considers this to be a faithful depiction of the transfer to the customer of revenue over time due to short cycle time and immaterial work-in-process balances. The majority of contracts typically require payment within 30 to 90 days after transfer of ownership to the customer.

Service revenue includes repairs, non-recurring engineering, 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. Non-recurring engineering arrangements are typically recognized over time under 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. The majority of contracts typically require payment within 90 days.

The Company's revenue recognition policy is consistently applied across the Company's segments, product lines, services, and geographical locations. For the periods covered herein, the Company measures revenue based on the amount of consideration it 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. The Company determines 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, the Company expenses 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. The Company has elected to recognize the costs for freight and shipping when control over products has transferred to the customer as an expense in cost of goods sold.

The Company monitors and tracks the amount of product returns and reduces revenue at the time of shipment for the estimated amount of future returns, based on historical experience.

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

The Company believes 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 5. Revenue from Contracts with Customers.

Research and Development

Research and Development. Research and development 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 research and development expenses as incurred.

Share-Based Compensation

Share-Based Compensation. Share-based compensation arrangements require the recognition in net earnings (loss) of the grant date fair value of stock compensation (for equity-classified awards). The Company recognizes 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 the Company’s historical experience of pre-vesting cancellations. The Company 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.

Accumulated Other Comprehensive Loss

Accumulated Other Comprehensive Income (Loss). Accumulated other comprehensive income (loss) 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. Accumulated other comprehensive income (loss) is a component of shareholders’ equity and consists of accumulated foreign currency translation adjustments, changes in the fair value of interest rate swap derivative instruments, and pension adjustments.

Fair Value Measurements

Fair Value Measurements. The Company applies 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, the Company considers the principal or most advantageous market in which the Company 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.

Recently Issued Financial Accounting Standards

Financial Instruments - Credit Losses

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, Financial Instruments - Credit Losses (Topic 326), which modifies the measurement of expected credit losses on certain types of financial instruments, including trade receivables. The Company adopted this standard on July 1, 2020. The adoption did not have a material impact on the Company's consolidated financial statements.

Pronouncements Currently Under Evaluation

In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40) ("ASU 2020-06"). The update simplifies the accounting for convertible instruments by eliminating two accounting models (i.e., the cash conversion model and beneficial conversion feature model) and reducing the number of embedded conversion features that could be recognized separately from the host contract. ASU 2020-06 also enhances transparency and improves disclosures for convertible instruments and earnings per share guidance. ASC 2020-06 is effective for annual reporting periods beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. This update permits the use of either the modified retrospective or fully retrospective method of transition. We plan to adopt this ASU as of July 1, 2021. We estimate the impact of adopting ASU 2020-06 will result in an increase in net debt of $15 million, a decrease in the deferred tax liability of $3 million, a decrease in common stock of $56 million, and an increase in retained earnings of $45 million. The adoption will result in a decrease of interest expense of approximately $12 million in fiscal year 2022.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients to ease the potential burden of accounting for the effects of reference rate reform as it pertains to contract modifications of debt and lease contracts and derivative contracts identified in a hedging relationship. These amendments are effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Company is in the process of evaluating the impact of the pronouncement.
