2     II-VI INCORPORATED 2021 ANNUAL REPORT
STAKEHOLDER LETTER
Extraordinary achievements come from truly caring about 
serving one another and those who will follow us. Our 
fiscal year 2021 achievements were extraordinary and, 
more importantly, we are well positioned to achieve much 
more in the coming months, years, and decades. 
Super-Cycles and Irreversible 
Megatrends
Fiscal year 2021 was driven by a super-cycle in the 
buildout of computing, optical communications, 
and wireless infrastructure; an acceleration of the 
electrification of the global transportation infrastructure; 
and the early stages of recovery in the world’s industrial 
economies. Inventory levels decreased, resulting in 
customers throughout our ecosystems experiencing 
shortages of critical component supplies. We 
experienced an increased demand from customers for 
the differentiated products we make that are enabling 
many irreversible market megatrends.
Among these market megatrends are the digital 
transformation of information networks and the 
convergence of communications, computing, and 
sensing as seen in the growth in 5G, augmented reality 
and virtual reality, machine learning, artificial intelligence, 
smart factories, and smart vehicles. Combined with the 
imperative of establishing green and clean transportation 
as part of the world’s efforts to mitigate climate change 
and the risks associated with it, fiscal year 2021 was a 
turning point, as society’s demands for applications that 
are mobile, intelligent, and electric continued to provide 
secular tailwinds. 
Accomplishments for Fiscal Year 2021
We had three objectives this year: take care of our 
people; serve our customers; and invest, manage, and 
grow to drive long-term value for our shareholders. I am 
pleased to say we accomplished all three objectives and 
rang the bell on a number of records along the way.
• Our people: Since the earliest days of the pandemic, we 
acted swiftly to safeguard our people and our facilities 
around the world. We have since further invested in 
To our customers, business partners, 
shareholders, and the people around 
the world who we serve with our 
products, services, and our presence 
in your communities: I CARE. 
For all of us who are a part of the One II-VI Family, our 
I CARE values of Integrity, Collaboration, Accountability, 
Respect, and Enthusiasm describe what we do, how we 
achieve success, and ultimately who we are. We care about 
serving our customers. We care about being trusted and 
reliable business partners. We care about our colleagues 
by creating a culture of opportunity, diversity, inclusion, 
fairness, and the personal and collective achievement that 
comes from an open, supportive, diverse, and inclusive 
environment. We care about our mission of enabling the 
world to be safer, healthier, closer, and more efficient. We 
care about achieving sustainability for future generations, 
which is among the highest callings of our time.

high-speed transceivers. Our breakthroughs 
in semiconductor laser technology were key 
innovations that enable these transceivers.
‐ Silicon carbide materials and devices:
We announced a series of investments to 
enable the electrification of the transportation 
infrastructure, acquired differentiated epitaxial 
and ion implantation capabilities, licensed 
key IP from General Electric, and announced 
our bold plan to invest $1 billion over the next 
10 years in our silicon carbide platform.
‐ Optical filter capacity expansion: We began 
the work to double over the next five years our 
manufacturing capacity in the optical filters that are 
in high demand for PCR testing due to COVID-19, 
as well as for 5G optical access networks.
‐ Cooperation with Coherent: We announced 
a partnership with Coherent to co-market our 
remote laser processing heads with their fiber 
lasers, to meet the high demand for a variety 
of welding processes in electric vehicles.
Business Execution and Results
We completed another great year with record numbers, 
passing the $3 billion in revenue milestone. Our results 
demonstrated our disciplined execution of a diversified 
growth strategy and focus on operational excellence, cash 
flow, and prudent capital management. We strengthened 
our balance sheet through performance, including record 
full-year cash flow from operations of $574.4 million and 
record full-year free cash flow of $428.0 million, in addition 
to a strategic investment by Bain Capital. Not only are we 
delighted that Bain joined our shareholder community, but 
we also warmly welcome Steve Pagliuca, Managing Director 
of Bain Capital Private Equity, LP, to our Board of Directors. 
Looking Forward
While we have been reflecting on our remarkable 
growth trajectory over the last 50 years, our gaze is 
already on the future, as we anticipate the combination 
with Coherent. We look forward to welcoming another 
generation of leaders who will become a part of the 
One II-VI Family and carry forward our vision of a world 
transformed through innovative materials vital to a better 
life today and the sustainability of future generations. 
Acknowledgments
In this, our 50th year, I would especially like to 
acknowledge II-VI’s second CEO, Fran Kramer, for his role 
as Board Chair, helping guide us through the changes 
that the world is experiencing today. We are delighted 
that Fran will continue his long legacy with II-VI in his new 
role as Chair Emeritus, beginning in November 2021. 
Finally, I would like to express my deep personal gratitude 
to each and every one of our employees who care 
deeply and uphold our corporate values day in and day 
out. In that spirit, we all say with one voice, I CARE.

meet the evolving needs of many industries 
facing limits to their innovations and 
advancement due to limitations in materials. 
Since then, there have been countless heroes 
among us in our history who have made 
that vision a reality. During the first 50 years, 
we made many bold moves. Turning the 
page now to the future, we will continue to 
work toward a world transformed through 
innovative materials vital to a better life today 
and the sustainability of future generations.

MOBILE
Enhancing our 
Mobility Experience, 
Safety, and Security 
with 3D Sensing 
Today, II-VI produces vertical-cavity surface emitting 
laser (VCSEL) arrays for multiple end customers and 
applications. We envision the number of disruptive 
applications growing over time.
On the front of a smartphone, VCSEL arrays are used for 
facial biometrics, to unlock the screen, or to authenticate 
a user performing a secure financial transaction.
On the world-facing side of smartphones, VCSELs 
improve the quality of photos taken with embedded 
cameras. VCSELs could be used to scan and digitally 
recreate, with a smartphone app, a three-dimensional 
representation of a user’s surroundings. That allows 
additional information relevant to that user to be 
superimposed on the real scene, which is what is 
called augmented reality, or AR. For example, users 
can make measurements in their home or check the 
way a piece of furniture looks inside an apartment 
before making a purchase online. We can already see 
commercials on television illustrating these features.

Vertical Integration: VCSELs Illumination Modules
U.S. and European transportation safety regulators are increasingly recommending 
or requiring driver and occupancy monitoring systems in vehicles.
VCSEL arrays can be used for safety features in 
automotive cabins. They can provide information about 
the alertness of the driver and the position of passengers, 
which can prevent accidents or reduce injury with more 
accurate and timely deployment of airbags.
The growing adoption of advanced driver-assistance 
systems (ADAS) in next-generation vehicles is spurring 
the development of ultra-compact light detection 
and ranging (LiDAR) systems that can be seamlessly 
integrated in vehicles. In 2021, II-VI announced the 
introduction of its eye-safe pulsed lasers for LiDAR in 
automotive applications.

server-to-server and server-to-memory communications within 
the datacenter and between datacenters. This capability is now 
embedded in the lives of all of us as we access vital services. 
In fact, COVID-19 has shown us that these services are a lot 
more than a convenience. They are increasingly essential to 
our lives, and we can expect investments in the optical network 
infrastructure to continue for the foreseeable future.
Data Communication Networks

II-VI.COM     9
Semiconductor Lasers for Optical Communications
The laser is at the heart of any transceiver and is a key enabling component for higher-speed optical communications.
We have a variety of laser platforms including our vertical-cavity surface emitting laser, or VCSEL, for short-reach applications, 
our edge emitting directly modulated laser (DML) and our electro-absorption modulated laser (EML) for longer reach, and our 
tunable lasers for even longer reach. We are now getting ready for the next wave of high-speed optics at 800G with our 100G 
and 200G capable lasers.
The 5G buildout continues around the world, 
with over a million base stations planned for 
deployment in 2021. Significant roll-out plans have 
been announced recently in the U.S. and Europe. 
Other broadband access networks such as fiber-
to-the-home and low-orbit satellite networks are 
also being deployed. Collectively, these networks are 
known as access networks, because they provide 
access to internet services. All of the data generated 
through these access networks then travels over 
the optical network infrastructure, also known as 
transport networks. New applications enabled 
by the digital transformation, including artificial 
intelligence, machine learning, and the internet of 
things (IoT), continue to drive increased bandwidth 
at the edge of the network that in turn drives the 
need for bandwidth upgrades throughout the entire 
optical network infrastructure.

All of these advantages in total reduce the size, weight, and power budget of the vehicle in addition to achieving cost savings.
In August 2020, we added an industry-leading silicon 
carbide epitaxy technology to our platform by acquiring 
Ascatron in Kista, Sweden, now called II-VI Kista, a 
pioneer in silicon carbide epitaxial wafer technology. II-VI 
Kista has been developing a proprietary technology since 
the early ‘90s, now under the trademark 3DSiC®. In 2016, 
3DSiC was commercialized at scale on 100 and 150 mm 
diameter wafers. 3DSiC’s differentiated performance 
stems from the ability to grow very thick epitaxial layers, 
not only in one step, but in multiple regrowth steps, to 
create a buried-grid structure.
The value of 3DSiC is that it enables us to address a sweet 
spot in the market, which is power devices for applications 
above 1 kilovolt. We believe that the availability of our 
products will be well-timed with the market demand for 
these products.

Integration of multiple 
powertrain converters
We envision being part of the lithium battery supply chain 
with new battery cathode materials that will greatly enhance 
lithium battery performance. These materials leverage 
elements in Group VI of the periodic table, an extension of 
our core competency. The performance that we are already 
seeing with lithium-sulfur cathodes exceeds our original 
expectations in terms of energy capacity, power delivery, 
and charging time. More importantly, sulfur is available in 
great abundance. A 2020 report from the U.S. Geological 
Survey indicates the U.S. is the world’s largest producer of 
sulfur, with 20% of the world total sulfur source. In contrast, 
cobalt is a conflict mineral of which the U.S. produces less 
than 1% of the world total, an important consideration for 
the establishment of domestic and resilient supply chains.

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.

General Description of Business 
We develop, manufacture, and market engineered materials, optoelectronic components, and devices for use in optical 
communications, industrial, aerospace and defense, consumer electronics, semiconductor capital equipment, life sciences, and 
automotive applications and markets. We use advanced engineered materials growth technologies and proprietary high-precision 
fabrication, microassembly, optical thin-film coating, and electronic integration to manufacture complex optoelectronic devices 
and modules. Our products are deployed in a variety of applications, including (i) optical, data, and wireless communications 
products; (ii) laser cutting, welding, and marking operations; (iii) 3D sensing consumer applications; (iv) aerospace and defense 
applications including intelligence, surveillance, and reconnaissance; (v) semiconductor processing tools; and (vi) thermoelectric 
cooling and power-generation solutions. 
Through RD&E investments and its strategic acquisitions, II-VI has expanded its portfolio of materials and product platforms. 
We believe that the materials we grow and fabricate are differentiated by one or a combination of unique optical, electrical, 
thermal, and mechanical properties. II-VI’s optics are shaped by precision surfacing techniques to meet the most stringent 
requirements for flat or curved geometries, functionalized with smooth or structured surfaces, or with patterned metallization. 
Proprietary processes developed at our global optical coating centers differentiate our products’ durability against high-energy 
lasers and extreme operating environments. Optical coatings also provide the desired spectral characteristics, ranging from the 
ultraviolet to the far-infrared. 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.

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,

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 
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

Manufacturing Processes 
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 

 
14 
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. 
Aerospace and Defense Market 
 
II-VI’s aerospace and defense solutions enable mission-critical capabilities for applications in high-energy lasers (HELs); 
contested space; and intelligence, surveillance, and reconnaissance. From uniquely grown single crystals and advanced ceramics, 
to completely engineered gimbal subsystems, II-VI solutions are embedded on nearly every platform in the field as well as those 
under development. Recently acquired coherent laser beam combining and advanced lightweight gimbal technologies, along 
with domestically produced high-power fiber laser pumps and amplifiers, are enabling next-generation HEL systems and space-
based laser communications applications. With the addition of nanomachined single-crystal silicon and grating technologies, 
together with II-VI’s advanced HEL coating capabilities, we enable advanced spectral beam combining and novel 
microstructured surface capabilities, which are highly valued within the aerospace and defense industry.  
 
Our advanced missile warning, electro-optical targeting, and imaging systems are deployed on virtually every U.S. fixed-wing 
and rotary platform. Our advanced sapphire, germanium, and multispectral domes provide unique protection to our advanced 
imaging, seeker, and laser solutions that are packaged behind them. The domes provide hemispherical coverage for airborne, 
naval, and ground-based systems. 
 

 
15 
Our solutions for the Lunar Reconnaissance Orbiter (LRO) provided the first images proving that the footprints on the moon are 
still there. The LRO continues to orbit the moon and provide rich information for future lunar landing sites. The LRO camera, 
and more advanced derivatives, are the basis for many advanced space imaging applications being pursued by our customers. 
Our solution for the OSIRIS-REx mission enables the first-ever ability for a NASA satellite to touch down on an asteroid 
(Bennu) and to retrieve a sample and return it to Earth. Our advanced imaging lenses and windows ensure our customers’ 
vehicles are able to safely and accurately dock with the Space Station. Our advanced telescope solution for the Geostationary 
Lightning Mapper enables the GOES satellites to detect early lightning strikes and predict tornados a full 20 minutes before 
previous technology. It forms the basis for many of our customers’ advanced multispectral imaging solutions.  
 
II-VI’s Aerospace & Defense (A&D) Division maintains separate business development, accounting, finance, engineering, and 
manufacturing facilities in the United States with strictly controlled access; they are dedicated to our U.S. government-supported 
contracts.  
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.  

 
16 
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. 
 
Our industry-leading semiconductor lasers, optics, and materials are at the core of LiDAR systems embedded in advanced 
driver-assistance systems (ADAS) for autonomous vehicles. LiDAR sensors enable ADAS to perform functions such as 
emergency braking and adaptive cruise control. II-VI enables LiDAR sensors with a broad portfolio of components and modules, 
including high-power laser diodes, fiber amplifiers, frequency-modulated continuous wave detection solutions, optical filters for 
detection, mirrors for scanning, and thermoelectric coolers for temperature control. Our product offerings include edge-emitters 
and VCSELs that are capable of providing a wide range of peak powers for direct illumination and imaging for short- and long-
range LiDAR solutions. Emission and return windows on LiDAR systems are available in ultrahard bulk materials, such as SiC 
and diamond, and with optical coatings that are water-shedding and oil-resistant. Our thermoelectric coolers are qualified to 
automotive standards and enable LiDAR systems to operate with optimal performance and efficiency. 
 
New generations of vehicles will be equipped with a greater number of sensors that can monitor a driver’s alertness and let 
occupants interact with the console using touch sensing or gesture recognition. In the event of a collision, sensors can help 
provide critical information about the position and attention of occupants to activate restraints and deploy airbags in the best 
possible manner. II-VI’s products enable the most advanced in-cabin control and monitoring systems for the latest applications in 
human-vehicle interactions. Our VCSELs are ideal for optical touch sensors integrated in dashboards or steering wheels. Our 
VCSEL arrays can provide infrared cabin illumination and structured light projection to enable gesture recognition. 
 
Automotive manufacturers continue to differentiate their products with comfort features such as temperature-controlled car seats 
and cup holders, all of which require thermoelectric devices. II-VI offers thermal management solutions that are qualified to 
stringent automotive industry standards and tailored to various applications.

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 
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 

 
26 
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 
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 

 
27 
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: 
 
• 
the integration of management teams, strategies, technologies and operations, products, and services; 

 
28 
• 
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 
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 

 
29 
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 
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.  

 
30 
 
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. 
 

 
31 
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. 
 
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.  

 
32 
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.  
 
 
 
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 

 
33 
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 
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. 
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.  

 
34 
 
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.  
 
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, 
 
Natural disasters or other global or regional catastrophic events could disrupt our operations, give rise to substantial 
environmental hazards, and adversely affect our results.  

 
35 
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.  
 
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 
governmental trade action or economic sanctions may limit or preclude our ability to do business with certain customers.  

 
36 
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 
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.  
 
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.  
 

 
37 
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. 
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.  
 
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.  
 

 
38 
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.  
 
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.  
 
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.  
 

 
39 
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.  
 
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 

 
40 
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, 
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 

 
41 
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.  
 
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 

 
42 
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; 
• 
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 

 
43 
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. 
 
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 

 
44 
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. 
 
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. 
 

 
45 
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. 
 
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. 
 

 
46 
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.

LEGAL PROCEEDINGS 
The Company and its subsidiaries are involved in various claims and lawsuits incidental to its business. The resolution of each 
of these matters is subject to various uncertainties, and it is possible that these matters may be resolved unfavorably to the 
Company. Management believes, after consulting with legal counsel, that the ultimate liabilities, if any, resulting from such

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. 
 

 
51 
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.

Convertible Preferred Stock, as well as its underwritten public offering and sale of approximately 11 million shares of its 
common stock. See Note 11. Equity and Redeemable Preferred Stock, to our Consolidated Financial Statements contained in 
this Annual Report on Form 10-K for further details. 
As we grow, we are focused on scaling our Company and deriving the continued benefits of vertical integration as we strive to 
be a best in class competitor in all of our highly competitive markets. 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 

 
52 
(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.  

 
54 
 
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.   
 

 
55 
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. 
Fiscal Year 2021 Compared to Fiscal Year 2020 
The Company aligns its organizational structure into the following two reporting segments for the purpose of making 
operational decisions and assessing financial performance: (i) Compound Semiconductors and (ii) Photonic Solutions. The

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.  

 
56 
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.

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. 
Fiscal Year 2020 Compared to Fiscal Year 2019 
The Company aligned its organizational structure into the following two reporting segments for the purpose of making 
operational decisions and assessing financial performance: (i) Compound Semiconductors and (ii) Photonic Solutions. The

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.

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.

compared to operating income of $82 million for fiscal year 2019. The decrease in operating income during fiscal year 2020 
was primarily driven by the acquisition of Finisar, which includes unabsorbed operating costs incurred at the segment's 
Sherman, Texas wafer fabrication facility during the qualification phase.  In addition, the segment incurred acquisition related 
expenses associated with expensing of the fair value inventory write-up and other related acquisition expenses.

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 during the current period primarily 
included $34 million for net cash paid for the acquisitions of Ascatron AB and INNOViON Corporation and $146 million of 
capital expenditures to continue to increase capacity to meet the growing demand for the Company’s product portfolio.  
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. Net cash provided by financing activities during the 
fiscal year ended June 30, 2020 included net borrowings on long-term debt of $1,256 million primarily to fund the acquisition 
of Finisar, and $14 million of cash received from exercises of stock options.  Net cash provided by financing activities was 
offset by $64 million of debt issuance costs associated with the increased borrowings, $29 million of cash payments in 
satisfaction of employees’ minimum tax obligations from the vesting of equity awards and a $2 million payment to repurchase 
common stock through the Company's share repurchase program. 
 
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 

 
61 
(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 

 
62 
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.

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.

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.

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.

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.

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. 

 
69 
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 

 
78 
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. 

 
79 
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 

 
80 
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. 

 
81 
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 

 
82 
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 

 
83 
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.

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.

(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.

(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 Semiconductor segment and is attributed to the workforce acquired as part of the 
transaction.  The goodwill is non-deductible for income tax purposes.  Technology is being amortized with a useful life of 
approximately 16 years.  Customer lists are being amortized with a useful life of approximately 14 years.  Transaction expenses 
for the year ended June 30, 2021 were insignificant.

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”). 

 
90 
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 

 
91 
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 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:

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. 

 
96 
 
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:

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: 
 

 
97 
• 
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.

Series B-1 Convertible Preferred Stock that does not require bifurcation for separate accounting.  
 
Common Stock Offering 
 

 
98 
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 
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

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):

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:

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:

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.

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.

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.

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:

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 

 
105 
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, 

 
108 
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 

 
109 
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:

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.

CONTROLS AND PROCEDURES 
Evaluation of Disclosure Controls and Procedures 
The Company’s management evaluated, with the participation of the Company’s Chief Executive Officer, and the Company’s 
Chief Financial Officer and Treasurer, the effectiveness of the Company’s disclosure controls and procedures (as defined in 
Rules 13a-15(e) and 15d-15(e) of the Exchange Act) as of the end of the period covered by this Annual Report on Form 10-K. 
The Company’s disclosure controls were designed to provide reasonable assurance that information required to be disclosed in 
reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods 
specified in the rules and forms of the SEC. It should be noted that the design of any system of controls is based in part upon 
certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in 
achieving its stated goals under all potential future conditions, regardless of how remote. However, the controls have been 
designed to provide reasonable assurance of achieving the controls’ stated goals. Based on that evaluation, the Chief Executive 
Officer and Chief Financial Officer concluded that, as of June 30, 2021, the Company’s disclosure controls and procedures are 
effective.
