RISK FACTORS SUMMARY

You should carefully consider the information set forth under the heading "Risk Factors" in Item 1A of this report before deciding whether to invest in

our securities. Below is a summary of the principal risks associated with an investment in our securities.

• We face risks related to our pending merger with II-VI, including our requirement to comply with certain restrictions on our operations until
closing, the possibility that the merger agreement with II-VI will be terminated or expire prior to the completion of the merger, diversion of
management's attention, potential business uncertainty, including disruption of our relationships with third parties and employees, restrictions on
our business activities and litigation related to the merger.

• Our business, financial condition and results of operations may be materially adversely affected by the novel coronavirus ("COVID-19") pandemic

and the related private and public sector responses to the pandemic.

• Our operating results and stock price have varied in the past and will continue to be subject to fluctuations based upon numerous factors, including

those discussed under the heading "Risk Factors" in Item 1A and throughout this report.

• Our dependence on sole source or limited source suppliers for some of the key components and materials used in our products makes us susceptible

to supply shortages or price fluctuations that could adversely affect our business, particularly our ability to meet our customers' delivery
requirements.

• Disruption in our global supply chain could negatively impact our businesses.
• We participate in the microelectronics market, which requires significant research and development expenses to develop and maintain products and

a failure to achieve market acceptance for our products could have a significant negative impact on our business and results of operations.
• We participate in the flat panel display market, which has a relatively limited number of end customer manufacturers. Our backlog, timing of net
sales and results of operations could be negatively impacted in the event we face any significant periods with few or no orders or our customers
reschedule or cancel orders.

•

•

Some of our laser systems are complex in design and may contain defects that are not detected until deployed by our customers, which could
increase our costs and reduce our net sales.

Continued volatility in the advanced packaging and semiconductor manufacturing markets could adversely affect our business, financial condition
and results of operations.

• Our future success depends on our ability to increase our sales volumes and decrease our costs to offset potential declines in the average selling

prices of our products.

• We face risks associated with our worldwide operations and sales that could harm our financial condition and results of operations.

• We depend on skilled personnel to operate our business effectively, and if we are unable to retain existing or hire additional personnel when needed,

or manage transitions among members of our leadership team, our ability to develop and sell our products could be harmed.

•

•

•

The long sales cycles for many of our products may cause us to incur significant expenses without offsetting net sales.

The markets in which we sell our products are intensely competitive and increased competition could cause reduced sales levels, reduced gross
margins or the loss of market share.

If we fail to accurately forecast component and material requirements for our products, we could incur additional costs and incur significant delays
in shipments, which could result in a loss of customers.

• Our reliance on contract manufacturing and outsourcing may adversely impact our financial results and operations due to our decreased control

over the performance and timing of certain aspects of our manufacturing.

•

If we fail to effectively manage our growth or, alternatively, our spending during downturns, our business could be disrupted, which could harm our
operating results.

• Our market is unpredictable and characterized by rapid technological changes and evolving standards demanding a significant investment in

research and development, and, if we fail to address changing market conditions, our business and operating results will be harmed.

• Our future success depends on our ability to develop and successfully introduce new and enhanced products that meet the needs of our customers.

4

• Our and our customers' operations would be seriously harmed if our logistics or facilities or those of our suppliers, our customers' suppliers or our

contract manufacturers were to experience catastrophic loss.

• We may not be able to integrate the business of completed or future acquisitions successfully with our own, realize the anticipated benefits of such

acquisitions or manage our expanded operations, any of which would adversely affect our results of operations.

• We may not find suitable acquisition candidates in the future and we may not be able to successfully integrate and manage acquired businesses.

Any acquisitions we make could disrupt our business and harm our financial condition.

• Our increased level of indebtedness following our acquisition of Rofin Sinar Technologies, Inc. ("Rofin") could adversely affect us, including by

decreasing our business flexibility, and will increase our borrowing costs.

•

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

• Our cash and cash equivalents and short-term investments are managed through various banks around the world and volatility in the capital and
credit market conditions could cause financial institutions to fail or materially harm service levels provided by such banks, both of which could
have an adverse impact on our ability to timely access funds.

• We are exposed to credit risk and fluctuations in the market values of our investment portfolio.

•

•

If we are unable to protect our proprietary technology, our competitive advantage could be harmed.

Intellectual property related claims or litigation could be costly and divert the attention of our technical and management personnel. Adverse
resolution of litigation may harm our operating results or financial condition.

• Our information systems are subject to attacks, interruptions and failures.

• Difficulties with our enterprise resource planning system and other parts of our global information technology system could harm our business and
results of operation. If our network security measures are breached and unauthorized access is obtained to a customer's data or our data or our
information technology systems, we may incur significant legal and financial exposure and liabilities.

•

Changes in tax rates, tax liabilities or tax accounting rules could affect future results.

• As seen in recent actions of the governments of the United States and China, governmental regulations, including tariffs and duties, affecting the

import or export of products could negatively affect our business, financial condition and results of operations.

• We use standard laboratory and manufacturing materials that could be considered hazardous and we could be liable for any damage or liability

resulting from accidental environmental contamination or injury.

•

•

Compliance or the failure to comply with current and future environmental regulations could cause us significant expense.

Failure to maintain effective internal controls may cause a loss of investor confidence in the reliability of our financial statements or cause us to
delay filing our periodic reports with the SEC and adversely affect our stock price.

• We face particular privacy, data security and data protection risks due to laws and regulations regulating the protection or security of personal and

other sensitive data.

• Violations of anti-bribery, anti-corruption, and/or international trade laws to which we are subject could negatively affect our business, financial
condition and results of operations. Allegations thereof may entail significant distraction of management and allocation of resources in the
investigation and remediation thereof, which could also negatively affect our business, financial condition and results of operations.

•

Provisions of our charter documents and Delaware law, and our Change of Control and Leadership Change Severance Plan, may have anti-takeover
effects that could prevent or delay a change in control.

• Our bylaws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between us and

our stockholders, which could limit our stockholders' ability to utilize a different judicial forum for disputes with us or our directors, officers or
employees.

ITEM 1.  BUSINESS

GENERAL

Business Overview

PART I

We are one of the world's leading providers of laser solutions and optics for microelectronics, life sciences, industrial manufacturing, scientific and
aerospace and defense markets. More than a provider of lasers, we deliver systems to the world's leading brands, innovators, and researchers, all backed with
a global service and support network. Since inception in 1966, we have grown through internal expansion and through strategic acquisitions of
complementary businesses, technologies, intellectual property, manufacturing processes, and product offerings.

We are organized into two reporting segments: OEM Laser Sources ("OLS") and Industrial Lasers & Systems ("ILS"), based on the organizational
structure of the company and how the chief operating decision maker ("CODM") receives and utilizes information provided to allocate resources and make
decisions. This segmentation reflects the go-to-market strategies and synergies for our broad portfolio of laser technologies and products. While both
segments deliver cost-effective, highly reliable photonics solutions, the OLS business segment is focused on high performance laser sources and complex
optical sub-systems typically used in microelectronics manufacturing, medical diagnostics, and therapeutic applications, as well as in scientific research. Our
ILS business segment delivers high performance laser sources, sub-systems, and machine tools primarily used for industrial laser materials processing,
serving important end markets like automotive, machine tools, consumer goods, and medical device manufacturing as well as applications in aerospace and
defense.

Income (loss) from operations is the measure of profit and loss that our CODM uses to assess performance and make decisions. Income (loss) from

operations represents the net sales less the cost of sales and direct operating expenses incurred within the operating segments as well as allocated expenses
such as shared sales and manufacturing costs. We do not allocate certain operating expenses to our operating segments and we manage them at the corporate
level. These unallocated costs include stock-based compensation and corporate functions (certain management, finance, legal, and human resources) and are
included in Corporate and other. Management does not consider unallocated Corporate and other costs in its measurement of segment performance.

We were originally incorporated in California on May 26, 1966 and reincorporated in Delaware on October 1, 1990. Our common stock is listed on the

NASDAQ Global Select Market and we are a member of the Standard & Poor's MidCap 400 Index and the Russell 1000 Index.

Our fiscal year ends on the Saturday closest to September 30. Fiscal years 2021, 2020, and 2019 ended on October 2, October 3, and September 28,
respectively, and are referred to in this annual report as fiscal 2021, fiscal 2020, and fiscal 2019 for convenience. Fiscal 2021 and 2019 each included 52
weeks and fiscal 2020 included 53 weeks.

Additional information about Coherent, Inc. (referred to herein as the Company, we, our, or Coherent) is available on our web site at

www.coherent.com. We make available, free of charge on our web site, access to our annual report on Form 10-K, our quarterly reports on Form 10-Q, our
current reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934,
as amended (the "Exchange Act"), as soon as reasonably practicable after we file or furnish them electronically with the Securities and Exchange
Commission ("SEC"). Information contained on our web site is not part of this annual report or our other filings with the SEC. Any product, product name,
process, or technology described in these materials is the property of Coherent.

RECENT EVENTS

Merger Agreements and Termination Fee

On January 18, 2021, we entered into an Agreement and Plan of Merger with Lumentum Holdings Inc. ("Lumentum"), Cheetah Acquisition Sub, Inc.

("Lumentum Merger Sub I") and Cheetah Acquisition Sub LLC ("Lumentum Merger Sub II"), pursuant to which we agreed to be acquired for $100.00 in
cash per Coherent share and 1.1851 shares of Lumentum common stock per Coherent share. In light of unsolicited proposals received from each of MKS
Instruments, Inc. and II-VI Incorporated ("II-VI"), on March 9, 2021, we entered into an Amended and Restated Agreement and Plan of Merger with
Lumentum, Lumentum Merger Sub I and Lumentum Merger Sub II (the "Amended Lumentum Agreement"), pursuant to which we agreed to be acquired for
$175.00 in cash per Coherent share and 1.0109 shares of Lumentum common stock per Coherent share.

On March 25, 2021, we terminated the Amended Lumentum Agreement and entered into an Agreement and Plan of Merger with II-VI and Watson

Merger Sub Inc. ("II-VI Merger Sub") (the "II-VI Merger Agreement"), pursuant to which we agreed to be acquired for $220.00 in cash per Coherent share
and 0.91 of a share of II-VI common stock per Coherent share. In

6

connection with terminating the Amended Lumentum Agreement, we paid a termination fee of $217.6 million to Lumentum during our second quarter of
fiscal 2021. The termination fee, in addition to other costs related to the merger agreements with Lumentum and II-VI, is included in merger and acquisition
costs in our consolidated statements of operations.

Pursuant to the terms of the II-VI Merger Agreement, the acquisition of Coherent will be accomplished through a merger of II-VI Merger Sub with and

into Coherent (the "Merger"), with Coherent surviving the Merger as a wholly owned subsidiary of II-VI.

Pursuant to the terms of the II-VI Merger Agreement, and subject to the terms and conditions set forth therein, at the effective time of the Merger (the
"Effective Time"), each share of the common stock of Coherent (the "Coherent Common Stock") issued and outstanding immediately prior to the Effective
Time (other than (x) shares of Coherent Common Stock owned by II-VI, Coherent, or any direct or indirect wholly owned subsidiary of II-VI or Coherent or
(y) shares of Coherent Common Stock owned by stockholders who have properly exercised and perfected appraisal rights under Delaware law, in each case,
immediately prior to the Effective Time), will be cancelled and extinguished and automatically converted into the right to receive the following
consideration:

(A) $220.00 in cash, without interest, plus

(B) 0.91 of a validly issued, fully paid and non-assessable share of the common stock of II-VI.

The completion of Coherent's acquisition by II-VI is subject to customary closing conditions, including, among others, regulatory approvals in

applicable jurisdictions including the United States, Germany, China and South Korea.

Coronavirus pandemic (COVID-19)

In December 2019, COVID-19 cases were reported, and in January 2020, the World Health Organization ("WHO") declared it a Public Health

Emergency of International Concern. On February 28, 2020, the WHO raised its assessment of the COVID-19 threat from high to very high at a global level
due to the continued increase in the number of cases and affected countries, and on March 11, 2020, the WHO characterized COVID-19 as a pandemic. In an
effort to contain COVID-19 or slow its spread, governments around the world have enacted various measures from time to time, including orders to close all
businesses not deemed "essential," isolate residents in their homes or places of residence, and practice social distancing at and away from work. These
actions and the global health crisis caused by COVID-19 will continue to negatively impact global business activity, which could negatively affect our
revenue and results of operations. Each of the regions where we generate a majority of our revenue including Asia, Europe, and North America have been
and may continue to be impacted by COVID-19 in the future. The timing and extent of impact related to COVID-19 varies by country and region.

In determining the impact of the COVID-19 pandemic in relation to our net sales, in fiscal 2020 we compared our actual results to our most recently

published forecast and the net sales guidance range communicated in our quarterly earnings call. This forecast has been adjusted for known direct impacts to
our bookings and net sales from COVID-19 and other factors. Using this criteria, we estimate that our sales for fiscal 2020 were negatively impacted by the
COVID-19 pandemic by approximately $40.0 million. We believe the impact on fiscal 2021 sales was immaterial.

During fiscal 2020 and 2021, the global demand environment was uncertain at times given the effects of COVID-19 on many businesses, including
manufacturing facilities and customer confidence around the world. While we saw a partial recovery in order volumes in China in the latter half of March
and the third quarter of fiscal 2020, this coincided with declining bookings in other regions, particularly in North America, and to a lesser extent in Europe
and other countries in Asia. Beginning in the fourth quarter of fiscal 2020 and continuing in fiscal 2021, we saw global demand recover in all regions and
begin to return to a more normalized demand trend. However, we cannot predict future resurgences of COVID-19, particularly in light of the recent Delta
variant, and the impact that it may have on future demand for our products and services, particularly given the recent shutdown measures taken in certain
countries in Europe and Asia.

Currently, our major production facilities in Europe, Southeast Asia, and the United States remain open. At all of our locations, we have transitioned

from business continuity plans to return-to-operations plans while continuing to maintain high standards of employee safety and sanitization protocols. Our
Return to Operations Plans have a phased approach with the primary focus on employee safety, with a continuing requirement for "working from home" for
other members of our workforce wherever possible. We have vertically integrated manufacturing, and many of the components produced at certain of our
facilities supply other company facilities, are single sourced internally and are not available from third-party suppliers (for example our semiconductor
diodes are manufactured in Sunnyvale, California). While we do maintain a safety stock of critical components at our various locations, the scope, timing,
and duration of various government restrictions to address the COVID-19 pandemic could impact our internal supply chain. We have implemented certain
policy changes to help support our employees impacted by COVID-19. These measures have and will continue to increase the cost of our operations but the
magnitude and length of time of this impact is difficult to quantify at this time and may continue to be difficult to estimate in

7

the future. If our sales are reduced for an extended period or if our production output falls because of government restrictions, we may be required to reduce
payroll-related costs and other expenses in the future through layoffs or furloughs, even though we have not done so to date.

We continue to experience various supply disruptions throughout the supply chain and are working closely with our supply base to mitigate or remove

constraints as they become known. Supply constraints due to COVID-19 may impact the speed with which we are able to ramp up production if we
experience strong demand on certain products. We also continue to face supply chain constraints primarily related to logistics, including available air cargo
space and higher freight rates. Available cargo space on flights between the U.S. and Europe, and Europe and Asia has been and remains limited as a result
of the impact from COVID-19 and government and business responses to it, and this has increased shipping time and costs. In addition, shipments between
countries have been more severely impacted by COVID-19 and we are experiencing delays due to additional checks at border crossings, including within
Europe and Asia. There has also been sporadic restrictions on individual travel between certain states in the United States of America as well. Government
actions related to COVID-19 come on the heels of trade tensions between the United States and China, which may continue. We believe we have the ability
to meet the near-term demand for our products, but the situation is fluid and subject to change.

We continue to monitor the rapidly evolving conditions and circumstances as well as guidance from international and domestic authorities, including

public health authorities, and we may need to take additional actions based on their recommendations. There is considerable uncertainty regarding the
impact on our business stemming from current measures and potential future measures that could restrict access to our facilities, limit our manufacturing and
support operations, and place restrictions on our workforce, customers, and suppliers. The measures implemented by various authorities related to the
COVID-19 outbreak have caused us to change our business practices including those related to where employees work, the distance between employees in
our facilities, limitations on in-person meetings between employees and with customers, suppliers, service providers, and stakeholders as well as restrictions
on some shipping activities, business travel to domestic and international locations or to attend trade shows, investor conferences and other events. In March
of 2020, we formed a COVID Steering Committee to, among other things, propose, discuss, and implement best practices in response to COVID-19. The
COVID Steering Committee meets weekly and more often if required. All of our executive officers and many of our key senior-level employees are
members of the COVID Steering Committee.

The COVID-19 pandemic has significantly increased worldwide and regional economic uncertainty and decreased demand for our products in many

markets we serve, which could continue for an unknown period of time. In these circumstances, there may be developments outside of our control, including
the length and extent of the COVID-19 outbreak, government-imposed measures and our ability to ship as well as install products and/or service installed
products that may require us to adjust our operating plans. As such, given the dynamic nature of this situation, we cannot estimate with certainty the future
impacts of COVID-19 on our financial condition, results of operations or cash flows. However, we do expect that it could have an adverse impact on our
revenue as well as our overall profitability and could lead to an increase in inventory provisions, allowances for credit losses, and a volatile effective tax rate
driven by changes in the mix of earnings across our markets.

See "Risks Related to COVID-19 Pandemic" included under the heading "Risk Factors" in Item 1A of this annual report regarding the impact of

COVID-19.

Goodwill and other impairment charges

Based on our internal projections and the preparation of our financial statements for the quarter ended April 4, 2020, and considering the then-expected

decrease in demand due to the COVID-19 pandemic and other factors, we believed that the fair value of our ILS reporting unit might no longer have
exceeded its carrying value and performed an interim goodwill impairment test on the ILS and OLS reporting units. Based on the estimated fair value of the
ILS reporting unit, we recorded non-cash pre-tax goodwill impairment charges of $327.2 million in the quarter ended April 4, 2020. In addition, we
performed impairment tests on the long-lived assets allocated to the asset group of the ILS reporting unit, including intangible assets, property, plant and
equipment, and ROU assets as of April 4, 2020 and recorded non-cash pre-tax charges related to the impairment of intangible assets, property, plant and
equipment and ROU assets of the ILS reporting unit of $33.9 million, $85.6 million and $1.8 million, respectively, in the quarter ended April 4, 2020. See
Note 8, "Goodwill and Intangible Assets" and Note 11, "Leases" in the Notes to Consolidated Financial Statements under Item 8 of this annual report.

Restructuring

In June 2019, we internally announced our plans to exit a portion of our High Power Fiber Laser ("HPFL") business and consolidate all HPFL
manufacturing and engineering functions in our Tampere, Finland facility by transferring certain HPFL activities from our Hamburg, Germany facility. In
conjunction with this consolidation, we recorded restructuring charges in fiscal 2019 of $19.7 million. The charges primarily related to write-offs of excess
inventory, which is recorded in cost of sales, and estimated severance. We recorded charges of $1.1 million in fiscal 2020, primarily related to accelerated
depreciation and

project management consulting. We recorded no charges related to this project in fiscal 2021 as the project was completed in fiscal 2020.

We also vacated our leased facility in Santa Clara at the end of the lease term on July 31, 2020 and combined operations into our owned Santa Clara
headquarters. We did not incur material expenses in fiscal 2019 related to this project. In fiscal 2021 and 2020, we incurred costs of $0.1 million and $1.5
million, respectively, primarily related to accelerated depreciation, and completed the project in fiscal 2021.

In the fourth quarter of fiscal 2020, we began a restructuring program, as part of our good to great transformation, in our ILS segment which includes

management reorganizations, the planned closure of multiple manufacturing sites, and the right-sizing of global sales, service, order admin, marketing
communication, and certain administrative functions, among others. In the fourth quarter of fiscal 2020, we incurred costs of $2.6 million, primarily related
to severance. In fiscal 2021, we incurred costs of $12.2 million, primarily related to write-offs of excess inventory, accruals for vendor commitments and
warranty provisions, which are recorded in cost of sales, estimated severance, facility exit costs and accelerated depreciation.

See Note 19, "Restructuring Charges" in the Notes to Consolidated Financial Statements under Item 8 of this annual report.

Other

On April 19, 2021, we acquired Electro-Optics Technology, Inc. ("EOT") for approximately $29.3 million, excluding transaction costs. EOT is a

specialized U.S.-based components company, which we expect will enable us to vertically integrate and improve the performance of our directed energy
amplifier technology. See Note 4, "Business Combinations" in the Notes to Consolidated Financial Statements under Item 8 of this annual report.

INDUSTRY BACKGROUND

The word "laser" is an acronym for "light amplification by stimulated emission of radiation." A laser emits an intense coherent beam of light with
some unique and highly useful properties. Most importantly, a laser is orders of magnitude brighter than any lamp. As a result of its coherence, the beam can
be focused to a very small and intense spot, useful for applications requiring very high power densities including welding and other materials processing
procedures. The laser's high spatial resolution is also useful for microscopic imaging and inspection applications. Laser light can be monochromatic—all of
the beam energy is confined to a narrow wavelength band.

There are many types of lasers and one way of classifying them is by the material or medium used to create the lasing action. This can be in the form

of a gas, liquid, semiconductor, solid state crystal or fiber. Lasers can also be classified by their output wavelength: ultraviolet, visible, infrared or
wavelength tunable. We manufacture all of these laser types. There are also many options in terms of pulsed output versus continuous wave, pulse duration,
output power, beam dimensions, etc. In fact, each application has its own specific requirements in terms of laser performance. The broad technical depth at
Coherent enables us to offer a diverse set of product lines characterized by lasers targeted at growth opportunities and key applications. In all cases, we aim
to be the supplier of choice by offering a high-value combination of superior technical performance and high reliability.

Photonics has taken its place alongside electronics as a critical enabling technology for the twenty-first century. Photonics-based solutions are
entrenched in a broad array of industries that include microelectronics, flat panel displays, machine tools, automotive, and medical diagnostics, with
adoption continuing in ever more diverse applications. Growth in these applications stems from two sources. First, there are many applications where the
laser is displacing conventional mechanical devices because it can do the job faster, better or more economically. Second, there are new applications where
the laser is the enabling tool that makes the work possible, as in the conversion of amorphous silicon into poly crystalline silicon at low temperatures, where
lasers are used in the manufacturing of high resolution rigid and flexible OLED displays found in the latest smartphones, tablets and laptop computers.

Key laser applications include: semiconductor inspection; manufacturing of advanced printed circuit boards ("PCBs"); flat panel display
manufacturing; solar cell production; medical and bio-instrumentation; materials processing; metal cutting and welding; industrial process and quality
control; marking; imaging and printing; graphic arts and display; and research and development. For example, ultraviolet ("UV") lasers are enabling the
continuous move towards miniaturization, which drives innovation and growth in many markets. In addition, the advent of industrial grade ultrafast lasers
continues to open up new applications for laser processing.

Coherent occupies a unique position in the industry thanks to the breadth and depth of our product and technology portfolio, which includes laser
sources, critical or enabling photonics components and laser systems. Working closely with our customers we have developed specialized solutions that
include lasers, delivery and process optics in complete assemblies (sub-

9

systems), and for certain applications and markets we have also developed parts handling and automation to build complete laser systems.

Nowhere is the trend towards miniaturization and higher performance more prevalent than in the Microelectronics market where smartphones, tablets,
personal computers, televisions, and wearables are driving advances in displays, integrated circuits, and PCBs. In response to market demands and consumer
expectations, semiconductor and device manufacturers are continually seeking to improve their process and design technologies in order to manufacture
smaller, more powerful, and more reliable devices at lower cost. New laser applications and new laser technologies are a key element in delivering higher
resolution and higher precision at lower manufacturing cost.

We participate in three sub-markets in the microelectronics industry: (1) flat panel display manufacturing, (2) semiconductor front-end manufacturing,

and (3) advanced packaging and interconnects.

Microelectronics—flat panel display manufacturing

The high-volume consumer market is driving the production of flat panel displays in applications such as mobile phones, tablets, laptop computers,
televisions and wearables. There are multiple types of established displays, liquid crystal display ("LCD") and organic light emitting diodes ("OLED"), as
well as emerging displays (MicroLED), each based on different technologies. All of these technologies utilize laser applications in their manufacturing
process to enable improved yields, higher process speed, improved battery life, lower cost and/or superior display brightness, resolution and refresh rates.

Several display types require a high-density pattern of silicon thin film transistors. If this silicon is polycrystalline as opposed to amorphous, the
display performance is greatly enhanced. Excimer-based processes, such as excimer laser annealing ("ELA") enable high-volume production of low-
temperature polysilicon ("LTPS") on conventional glass substrates as well as flexible displays based on plastic substrates. Our excimer lasers provide a
unique solution for LTPS because they are the only industrial-grade excimer lasers optimized for this application. The current state-of-the-art product for this
application is our Vyper excimer laser and Linebeam systems. These systems deliver power ranges of 1200W to 3600W, enabling a critical manufacturing
process step on substrate sizes, currently, up to Generation 6. These systems are integral to the manufacturing process on all leading LTPS-based smartphone
displays and hold the potential for deployment in a variety of screens, including tablet, laptop, automotive displays, and OLED television. Excimer-based
LTPS is also enabling flexible OLED displays which have undergone rapid growth as they have been adopted into smartphones.

An emerging technology related to flat panel displays is MicroLED technology. The appeal of MicroLED is reduced electrical consumption for
improved battery life and higher absolute brightness relative to OLED. We are continuing to accelerate our efforts and investments in UV MicroLED
manufacturing solutions to help our customers develop the laser processes of record, so we can, in turn, develop the laser-based capital equipment systems
needed for mass production.

We see a co-existence of two technologies in the years to come, one being flexible OLED which will remain the dominant choice for mobile

applications in the long term, and also in MicroLED which may become the preferred technology in large diagonal high end television, and devices such as
watches or future smart glasses where brightness is a key advantage and

11

 
 
 
 
 
battery size is at a premium. We believe we are well positioned to remain the laser solutions display industry leader for all display technologies.

A modern flat panel display incorporates a number of different layers, some of which are thin films that need to be cut or structured. As film

thicknesses decrease over time, lasers are becoming the tool of choice to process these materials. Our DIAMOND CO  and Rapid series ultrafast lasers are
used for cutting flat panel display films.

2

We have developed a proprietary technology for cutting brittle materials such as glass and sapphire without debris and with zero kerf called SMART

Cleave

TM

, which is used for cutting brittle materials used in displays. This technology uses ultrafast lasers coupled with proprietary optics.

Our AVIA, Rapid, Monaco, and DIAMOND CO  lasers are also used in other production processes for flat panel displays. These processes include

2

drilling, cutting, patterning, marking, and yield improvement.

While the timing and adoption rate of an emerging display technology such as ‘micro’ LED (µLED) is difficult to gauge, it is likely to make use of
both similar technologies such as a LTPS backplane, as well as new ones, e.g. new versions of laser lift-off (LLO) and laser induced forward transfer (LIFT).
We expect that this will represent an expanding market opportunity into new display form factors for laser-based processes.

Microelectronics—semiconductor front-end manufacturing

The term "front-end" refers to the production of semiconductor devices which occurs prior to packaging.

As semiconductor device geometries decrease in size, devices become increasingly susceptible to smaller defects during each phase of the
manufacturing process and these defects can negatively impact yield. One of the semiconductor industry's responses to the increasing vulnerability of
semiconductor devices to smaller defects has been to use defect detection and inspection techniques that are closely linked to the manufacturing process.

Detecting defects is only the first step in preventing their recurrence. Once found, defects must be examined in order to identify their size, shape and

the process step in which the defect occurred. This examination is called defect classification. Identification of the sources of defects in the lengthy and
complex semiconductor manufacturing process has become essential for maintaining high yield production. Semiconductor manufacturing has become an
around-the-clock operation and it is important for products used for inspection, measurement and testing to be reliable and to have long lifetimes. Our
Azure, Paladin, Excimer, Ion, and OPSL lasers are used to detect and characterize defects in semiconductor chips.

Microelectronics—advanced packaging and interconnects

After a wafer is patterned, there are then a host of other processes, referred to as back-end processing, which finally result in a packaged encapsulated
silicon chip. Ultimately, these chips are then assembled into finished products. The advent of high-speed logic and high-memory content devices has caused
chip manufacturers to look for alternative technologies and materials to improve performance as well as reduce process costs. This search includes new
types of materials, such as low-k and thinner silicon. Our AVIA, Rapid, Monaco, and Matrix lasers provide economical methods of cutting and scribing
these wafers while delivering higher yields than traditional mechanical methods.

There are similar trends in chip packaging and PCB manufacturing, that is the requirement for more compact packaging and denser interconnects. In
many cases, lasers present enabling technologies. For instance, lasers are now the only economically practical method for drilling blind microvias in chip
substrates and in both rigid and flexible PCBs. These microvias provide for the tiny interconnects that are essential for enabling high-density circuitry
commonly used in smartphones, tablets, and advanced computing systems. Our DIAMOND CO  and AVIA diode pumped solid state ("DPSS") lasers are
the leading lasers in this application. The ability of these lasers to operate at very high repetition rates translates into faster drilling speeds and increased
throughput in microvia processing applications. In addition, multi-layer circuit boards require more flexible production methods than conventional printing
technologies can offer, which has led to widespread adoption of laser direct imaging ("LDI"). Our Paladin laser is used for this application.

2

We also offer market-leading solutions for laser marking of wafers and ICs, such as our PowerLine laser sub-systems.

Precision Manufacturing

Beginning in fiscal 2021, we increased our focus on Precision Manufacturing, a subset of the Materials Processing market, which demands more

precision and control than other parts of the laser material processing market, and targeted our R&D and our manufacturing capabilities towards new
products that will serve higher margin, defendable markets. Examples include medical device manufacturing, semiconductor wafer marking, and precision
welding. Within the Precision Manufacturing area we participate at three levels: components, laser sources and laser systems. In the components space, we

12

plan to introduce a whole new category of laser diode products that will allow us to address new applications and customers, dramatically increasing the size
of our servable market.

In fiscal 2021, we primarily supported five sub-markets in the materials processing industry: (1) automotive, (2) machine tools, (3) medical device, (4)

materials processing components and (5) consumer goods, as well as a number of smaller sub-markets. Our sales to this highly diverse set of markets
include components, laser sources, laser diagnostic equipment, and complete laser systems. At a high level, the drivers for laser deployment within the
materials processing sub-market are faster processing with higher yields, processing of new and novel materials, and more environmentally friendly
processes, all with higher precision. With the broadest product portfolio in the laser industry, we offer solutions for almost any application on any material to
our customers. The most common applications include cutting, welding, joining, drilling, perforating, scribing, engraving, and marking.

Lasers are used in a number of applications in the automotive sub-market, from fine processing of high precision parts to marking, as well as cutting of
metals and welding large components such as gear boxes and car bodies for customers including OEMs and their customers. With the increasing production
of electric vehicles, lasers are also playing a key role in the manufacture and welding of batteries used in these vehicles. We serve this market with a number
of our products including ultrafast, DPSS, CO , diode and ARM fiber lasers as well as systems in the areas of marking, scribing, cutting and welding.

2

We serve the machine tools sub-market with components, laser sources, and systems in applications including cutting, welding, marking, and additive

manufacturing. We offer fiber lasers with different performance points in terms of power levels and beam profiles to address specific applications. During
the past 12 months we have chosen to focus on specific lasers and processes including single mode lasers and advanced beam shaping options, e.g. the ARM
advanced high power fiber laser where the beam parameters can be optimized to deliver higher quality welds with a wide variety of metals which translate
into higher customer yields and enables more cost efficient designs. As a fully vertically integrated fiber and laser diode supplier, we are able to produce all
key components in-house. Other products include our full line up of CO2 lasers, DPSS, and ultrafast lasers.

The medical device sub-market is characterized by its need for high precision manufacturing with high levels of quality control which lends itself very

well to laser manufacturing. Applications include fine cutting and welding in addition to high quality and specialized marking. We serve this sub-market
with a number of lasers as well as a portfolio of systems.

In the consumer goods sub-market, we serve a large variety of applications in various industries, such as packaging, digital printing, jewelry, textiles,
security, and consumer electronics. We serve these industries with a broad offering of our products from lasers to laser tools. As a consequence, this market
represents a stable and growing opportunity for us.

In summary, we serve the materials processing market with a very broad product portfolio. Laser sources include the Diamond series mid-power CO
2

lasers; the DC series of high power CO  lasers; Highlight FL high power ARM fiber lasers; the DF series of high power diode laser systems; the
COMPACT, MINI and EVOLUTION series of low and mid power diode lasers; the AViA, Matrix, Flare, and Helios DPSS lasers; and the Monaco and
Rapid series of ultrafast lasers. Laser tools include the Performance, Select and Integral series of manual welding systems; the Exact, UW and MPS series of
modular and highly configurable laser processing systems; the EasyMark, EasyJewel, LabelMarker Advanced and Combiline laser marking systems; and the
META laser cutting tools. Laser sub-systems, i.e. laser sources combined with software, beam delivery, processing heads, process monitoring, pattern
recognition and vision, include the PowerLine series for marking; the StarFiber for welding and cutting; the PWS welding system; the QFS laser scribing
system; and the StarShape CO  laser-based systems.

Instrumentation

Instrumentation is one of our more mature commercial applications. Representative applications within this market include bio-instrumentation,
medical OEMs and scientific and research applications. We also support the laser-based instrumentation market with a range of laser-related components and
power and energy measurement products.

Bio-instrumentation

Laser applications for bio-instrumentation include confocal microscopy for biological imaging that allows researchers and clinicians to visualize
cellular and subcellular structures and processes with an incredible amount of detail; DNA sequencing where lasers provide automation and data acquisition
rates that would be impossible by any other method; drug discovery—genomic and proteomic analyses that enable drug discovery to proceed at very high
throughput rates; flow cytometry for analyzing and sorting single cells or populations of cells in a heterogeneous mixture, including blood samples; and
Raman spectroscopy which enables chemical analysis in a wide range of commercial applications. Our OBIS, Flare, Galaxy, Sapphire, BioRay, Genesis and
CellX lasers are used in several bio-instrumentation applications.

13

Medical therapy

We sell a variety of components and lasers to medical laser companies for use in clinical applications such as ophthalmology, aesthetic, surgical,
therapeutic and dentistry. Our DIAMOND series CO  lasers are widely used in dental, aesthetic and surgical markets. We have a leading position in Lasik
and photorefractive keratectomy surgery methods with our ExciStar XS excimer laser platform. We also provide ultrafast lasers for use in cataract surgery
and optical fibers for surgical applications.

2

The unique ability of our optically pumped semiconductor lasers ("OPSL") technology to match a wavelength to an application has led to the

development of a high-power yellow (577nm) laser for the treatment of eye related diseases, such as Age Related Macular Degeneration and retinal diseases
associated with diabetes. Other applications where our OBIS, Genesis and Sapphire series of lasers are used include the retinal scanning market in diagnostic
imaging systems as well as new ground breaking in-vivo imaging.

Scientific and Research

We are widely recognized as a technology innovator and the scientific market has historically provided an ideal "test market" for our leading-edge

innovations. These have included ultrafast lasers, DPSS lasers, continuous-wave ("CW") systems, excimer lasers and water-cooled ion gas lasers. Our
portfolio of lasers that address the scientific research market is broad and includes our Acuity, Chameleon, Chameleon Discovery, COMPexPro, Astrella,
Revolution, Fidelity, Legend, Libra, Monaco, Vitara, Mephisto, Mira, Genesis and Verdi lasers. Many of the innovations and products pioneered in the
scientific marketplace have become commercial successes for both our OEM customers and us.

We have a large installed base of scientific lasers which are used in a wide range of applications spanning virtually every branch of science and
engineering. These applications include biology and life science, engineering, chemistry and physics. Many of these applications require the use of ultrafast
lasers that enable the generation of pulses short enough to be measured in femto- or attoseconds (10  to 10  seconds). Because of these very short pulse
durations, ultrafast lasers enable the study of fundamental physical and chemical processes with temporal resolution unachievable with any other tool. These
lasers also deliver very high peak power and large bandwidths, which can be used to study many different areas. Some of these are now finding their way
into mainstream applications, such as microscopy or materials processing. The use of ultrafast lasers such as the Chameleon, Fidelity and Monaco in
microscopy is now a common occurrence in bio-imaging labs, and they have become a crucial tool in modern neuroscience research.

Aerospace and defense

In fiscal 2021, we began disclosing aerospace and defense as a separate market application. Previously, this was included in our OEM Components and

Instrumentation market application in fiscal 2020. We serve the aerospace and defense markets with components and laser sources in a number of
applications including Directed Energy weapons, as well as technology for target designation and countermeasures. Additional areas include fiber optic
gyroscopes, specialty large diameter optics and entire telescope payloads for intelligence, surveillance & reconnaissance. In particular, directed energy has
seen rapid growth in the last couple of years, driven largely by the promise of being able to deter and repel asymmetrical threats such as drones in an
effective and economical manner.

FUTURE TRENDS

Microelectronics

Lasers are widely used in mass production microelectronics applications largely because they enable entirely new manufacturing and testing

capabilities that cannot be realized any other way. These laser-based fabrication and testing methods provide a level of precision, typically on a micrometer
and nanometer level, that is unique, fast and touch free, delivers superior end products, increases yields, and/or reduces production costs. We anticipate this
trend to continue, driven primarily by the increasing sophistication and miniaturization of consumer electronic goods, resulting in increasing demand for
better displays, more bandwidth and memory, and all packaged into devices which are lighter, thinner and consume less power. We believe that we are well
positioned to continue to capitalize on the current market trends.

Excimer-based LTPS is a key technology in the production of high resolution rigid and flexible OLED displays as well as future display technologies.

Another key technology related to flat panel displays is that of the emerging MicroLED technology. The appeal of MicroLED is reduced electrical

consumption for improved battery life and higher absolute brightness relative to OLED. We are continuing to accelerate our efforts and investments in
excimer laser-based MicroLED processes to help our customers develop the laser processes of record, creating a laser-based capital equipment market for
mass production.

14

Demand for CO , Avia, Matrix, Rapid, Monaco, Helios and direct diode lasers provides solutions for related flat panel display touch panel, film

2

cutting, light guide technology, repair and frit welding applications.

The trend for thinner and lighter devices is impacting the glass substrates used in today's mobile devices requiring thinner glass with higher degrees of
mechanical strength and scratch resistance. Mechanical means of cutting these glass and sapphire pieces are no longer adequate to meet future requirements
and we expect lasers to play an increased role. Our CO Monaco and Rapid lasers together with our proprietary SmartCleave technology are well positioned
to take advantage of this trend.

2, 

These same lasers, plus Monaco, Rapid, and CO  are also widely adopted for back end Advanced Packaging and Interconnect (API) applications. With
dimension roadmaps showing a decade of dimension shrink on PCBs, interconnects, Silicon scribe widths and wafer thickness, and driven by developments
such as 5G, we believe that our portfolio of lasers aligns well with these demands as well as new processes that could be enabled by our lasers, to meet the
increasing demands and decreasing tolerances of these markets.

2

Semiconductor devices look set to continue shrinking device geometries, as well as expanding vertically into new 3D structures. Such development
requires sophisticated testing in order to enhance yields. We believe our many UV laser sources (such as Azure, Paladin, Avia, Rapid, ExiStar, and OPSL)
will continue to find increasing adoption, since their unique optical properties align well with the demands of a nanometer scale world. The semiconductor
capital equipment market remains strong, and we are anticipating this trend continuing in fiscal 2022. Furthermore, we also believe we will benefit from
further adoption of sophisticated semiconductor testing techniques.

While we experienced a softening of the demand in fiscal 2019 and fiscal 2020, we experienced a resumption of investment in OLED manufacturing

capacity in fiscal 2021. It is difficult to precisely determine the timing and impact of this OLED investment on our fiscal 2022 and longer term revenues
even as additional vendors ramp their OLED production rates.

Precision Manufacturing

The materials processing market is the most diverse of all the markets we serve and a large cross section of our products are used in this market. In

fiscal 2021, we began to focus on Precision Manufacturing, a subset of the Materials Processing market, where we participate well both in terms of market
share and margins on three levels of components, laser sources and laser systems. We are concentrating our R&D and our manufacturing capabilities
towards new products that will serve higher margin, defendable markets. We sell components, laser sources and complete laser systems. There are many
drivers at play, but at a high level they involve faster processing with higher yields, processing of new materials, more environmentally friendly processes
and higher precision.

The automotive industry is undergoing rapid changes that present opportunities for further use of lasers. Trends such as using new materials to develop

lighter cars and emission-reduced electric vehicles require new processes for welding, cutting and drilling. We believe this will lead to further adoption of
lasers and tools based on high power fiber and diode lasers, as well as ultrafast and CO  lasers. In particular, we believe our ARM laser technology offers
competitive advantages versus alternative solutions especially in the rapidly growing area of battery welding and manufacturing.

2

We expect to see select opportunities for our products in the machine tools industry in a variety of broad-based applications including newer

applications such as laser cladding and heat treatment.

In the consumer goods market, we serve a large variety of applications in various industries, such as packaging, digital printing, jewelry, textiles,
security and consumer electronics. We serve these industries with a broad offering of our products from lasers to laser tools. As a consequence, this market
represents a stable and growing opportunity for us.

We supply the medical device market with a variety of lasers and laser systems in applications such as fine cutting and welding as well as marking.

This market is set to continue to grow in the foreseeable future as the population becomes older and advanced medical procedures spread outside the
traditional markets in US, Europe and Japan.

Instrumentation

Instrumentation is one of our more mature commercial applications. Representative applications within this market include bio-instrumentation,

medical therapy, and scientific and research applications.

We are an OEM supplier to the bio instrumentation market which includes flow cytometry, microscopy and DNA sequencing, all of which are enjoying

solid growth on a worldwide basis with some local variations. In this field, our OPSL technology gives us differentiated products at a number of important
wavelengths. This advantage coupled with strong focus on meeting our customers' demands for more compact and cost effective sources as well as
integrated laser sub-systems has resulted in growth for us in this market and we expect that to continue.

15

In the medical therapy market, we are an OEM laser supplier to medical system manufacturers in a number of clinical segments. In this area, we see

stable business with several opportunities for growth. We supply excimer lasers used in refractive eye surgery and are actively involved in further
developments in laser vision correction. We also have opportunities in dental procedures for both hard and soft tissue applications, with greatly improved
patient comfort and outcome. In the area of retinal treatment, photocoagulation based on our Genesis OPSL yellow lasers are being used since the
wavelength is particularly suitable for the treatment of blood vessels. We are an OEM supplier of CO  and semiconductor lasers to the major manufacturers
of equipment used in the latest aesthetic procedures.

2

Worldwide scientific funding is expected to remain relatively stable, with some regions growing and others holding their current level. Potential
growth areas include the strong push in neuroscience to better understand how the brain functions. Lasers play a very important role in imaging brain
structure as well as tracking activity using techniques such as optogenetics. We believe that our current and upcoming products are well positioned to take
advantage of the growing scientific interest and funding in this area. In physics and chemistry applications, our recent product introductions of high
performance and industrially hardened ultrafast products have been very well received. While this is a very competitive market, we expect that our new
products will position us for growth.

Aerospace and defense

Governments have made and continue to make investments in the development of directed energy systems, both offensive and defensive. We have a
number of product offerings which support these development efforts. A key differentiator for us in this market is having a U.S.-based supply chain for all
critical components, many of which are vertically integrated within Coherent, which we believe is advantageous to serve this market. Our U.S. Defense
customers have made it clear that a secure, U.S.-based supply chain is and will be required moving forward. Our fabrication process includes epitaxial
growth for our own laser diodes and packaged diodes in the U.S. and we also supply the specialty single mode amplifier fiber, critical for every directed
energy amplifier. We own several other businesses that make critical components and in April 2021, we completed the purchase of Electro-optics
Technology, Inc., a highly specialized U.S.-based components company, which will enable us to vertically integrate and improve the performance of our
directed energy amplifier technology.

*Coherent sells its laser measurement and control products into a number of these applications.

In addition to the products we provide, we invest routinely in the core technologies needed to create substantial differentiation for our products in the

marketplace. Our semiconductor, crystal, fiber and large form factor optics facilities all maintain an external customer base providing value-added solutions.
We direct significant engineering efforts to produce unique solutions targeted for internal consumption. These investments, once integrated into our broader
product portfolio, provide our customers with uniquely differentiated solutions and the opportunity to substantially enhance the performance, reliability and
capability of the products we offer.

TECHNOLOGIES

Diode-pumped solid-state lasers (DPSS)

DPSS lasers use semiconductor lasers to pump a crystal to produce a laser beam. By changing the energy, optical components and the types of crystals

used in the laser, different wavelengths and types of laser light can be produced.

The efficiency, reliability, longevity and relatively low cost of DPSS lasers make them ideally suited for a wide range of OEM and end-user

applications, particularly those requiring 24-hour operations. Our DPSS systems are compact and self-contained sealed units. Unlike conventional tools and
other lasers, our DPSS lasers require minimal maintenance since they do

17

not have internal controls or components that require adjusting and cleaning to maintain consistency. They are also less affected by environmental changes
in temperature and humidity, which can alter alignment and inhibit performance in many systems.

We manufacture a variety of DPSS laser types for different applications including semiconductor inspection; advanced packaging and interconnects;

laser pumping; spectroscopy; bio-agent detection; DNA sequencing; drug discovery; flow cytometry; entertainment lighting (display); medical; rapid
prototyping and marking, welding, engraving, cutting and drilling.

Fiber Lasers, Fiber Components and Fiber Assemblies

Fiber lasers use semiconductor lasers to pump a doped optical fiber to produce a laser beam. The unique features of a fiber laser make them suitable

for producing high power, continuous wave laser beams. Our emphasis is on the design and manufacture of highly differentiated fiber lasers that provide
advantages and/or are enabling in certain applications. For example, our ARM laser offers dynamically adjustable beam profiles that improve welding
results compared to standard fiber lasers and is able to weld new composite materials.

We are one of the world's leading OEM suppliers of Active Fiber for fiber lasers - selected for our combination of high performance and consistent
quality. In addition, we are a volume supplier of Specialty Passive Fiber, High Power Fiber Cables, Fiber Switches, Fiber-to-Fiber Couplers, as well as fiber
laser amplifiers for directed energy applications. In addition, many of the fiber components offered in the broader market, such as Fiber Bragg Gratings and
Fiber Combiners, have our fiber components in them.

Gas lasers (CO, CO , Excimer, Ion)

2

The breadth of our gas laser portfolio is industry leading, encompassing CO, CO , excimer and ion laser technologies. Gas lasers derive their name

2

from the use of one or more gases as a lasing medium. They collectively span an extremely diverse and useful wavelength range, from the very deep
ultraviolet to the far infrared. This diverse range of available wavelengths, coupled with high optical output power, and an abundance of other attractive
characteristics, makes gas lasers extremely useful and popular for a variety of microelectronics, scientific, therapeutic and materials processing applications.
For example, the CO  and CO lasers are unique in their ability to process non-metal materials.

Optically Pumped Semiconductor Lasers ("OPSL")

Our OPSL platform is a surface emitting semiconductor laser that is energized or pumped by a semiconductor laser. The use of optical pumping

circumvents inherent power scaling limitations of electrically pumped lasers, enabling very high powered devices. A wide range of wavelengths can be
achieved by varying the semiconductor materials used in the device and changing the frequency of the laser beam using techniques common in solid state
lasers. The platform leverages high reliability technologies developed for telecommunications and produces a compact, rugged, high power, single-mode
laser.

Our OPSL products are well suited to a wide range of applications, including the bio-instrumentation, therapeutics and graphic arts and display

markets.

Semiconductor lasers

High power edge emitting semiconductor diode lasers use the same principles as widely-used CD and DVD lasers, but produce significantly higher

power levels. The advantages of this type of laser include smaller size, longer life, enhanced reliability and greater efficiency. We manufacture a wide range
of discrete semiconductor laser products with wavelengths ranging from 650nm to over 1000nm and output powers ranging from 1W to over 100W, with
highly integrated products in the kW range. These products are available in a variety of industry standard form factors including the following: bare die,
packaged and fiber coupled single emitters and bars, monolithic stacks and fully integrated modules with microprocessor controlled units that contain power
supplies and active coolers.

Our semiconductor lasers are used internally as the pump lasers in DPSS, fiber and OPSL products that are manufactured by us, as well as a wide
variety of external medical, OEM, defense and industrial applications, including aesthetic (hair removal, cosmetic dentistry), graphic arts, counter measures,
rangefinders, target designators, cladding, hardening, brazing and welding.

Ultrafast ("UF") Lasers

UF lasers are lasers generating light pulses with durations of femtoseconds (10  seconds) to a few tens of picoseconds (10  seconds). These types of

-15

-12

lasers are used for medical, advanced microelectronics and materials processing applications as well as scientific research. UF laser oscillators generate a
train of pulses at 50-100 MHz, with peak powers of tens of kilowatts, and UF laser amplifiers generate pulses at 1-2000 kHz, with peak powers up to several
Terawatts.

18

The extremely short duration of UF laser pulses enables temporally resolving fast events like the dynamics of atoms or electrons. In addition, the high

peak power enables so-called non-linear effects where several photons can be absorbed by a molecule at the same time. This type of process enables
applications like multi-photon excitation microscopy or ablation of materials with high precision and minimal thermal damage. The use of our ultrafast
lasers in applications outside science continued to grow as it offers unparalleled quality of results, particularly in microelectronics and materials processing
applications.

Integrated Laser Solutions: Systems and Sub-systems

In most cases, our lasers are integrated into machine tools or systems to perform a specific task, e.g. manufacturing of electronic components or

performing a procedure on a patient. Inside the system the laser is typically combined with delivery optics and beam steering devices, such as scanning
galvanometers, to deliver the laser beam to the workpiece.

In addition to offering laser sources, we also offer solutions comprising beam delivery optics, mechanics and control electronics including software.
We believe that these 'sub-systems' allow us to leverage our expertise in laser processing and optical design into superior solutions for our customers, with
applications that can offer higher value and/or faster time to market. We have developed proprietary hardware, firmware and software in this area. Laser sub-
systems often include vision systems, process monitoring and monitoring of the system itself. Our sub-system products include: PowerLine series for
marking; the StarFiber for welding and cutting; the PWS welding system; the QFS laser scribing system; and the StarShape CO  laser-based systems.

2

In select cases we also offer complete laser systems which include the laser sub-system as well as a material handling capability inside a class 1 laser

safety enclosure, ready to be used in production or development environments. Our laser systems products include: the Performance, Select and Integral
series of manual welding systems; the Exact, UW and MPS series of modular and highly configurable laser processing systems; the EasyMark, EasyJewel,
LabelMarker Advanced and Combiline laser marking systems; the META laser cutting tools; and the PWS mini welding system.

SALES AND MARKETING

We primarily market our products in the United States through a direct sales force. We sell internationally through direct sales personnel located in
Canada, China, France, Germany, Israel, Italy, Japan, the Netherlands, South Korea, Singapore, Spain, Taiwan, and the United Kingdom, as well as through
independent representatives in certain jurisdictions around the world. Our foreign sales are made principally to customers in South Korea, China, Germany,
Japan, as well as other European and Asia-Pacific countries. Foreign sales accounted for 77% of our net sales in fiscal 2021, 76% of our net sales in fiscal
2020, and 76% of our net sales in fiscal 2019. Sales made to independent representatives and distributors are generally priced in U.S. Dollars. A large
portion of foreign sales that we make directly to customers are priced in local currencies and are therefore subject to currency exchange fluctuations. Foreign
sales are also subject to other normal risks of foreign operations such as protective tariffs, export and import controls, and political instability.

We had one customer, Advanced Process Systems Corporation, who contributed more than 10% of revenue during each of fiscal 2021, 2020, and 2019.

To support our sales efforts we maintain and continue to invest in a number of applications centers around the world, where our applications experts

work closely with customers on developing laser processes to meet their manufacturing needs. The applications span a wide range, but are mostly centered
around the materials processing and microelectronics markets. Locations include several facilities in the US, Europe, and Asia.

We maintain customer support and/or field service staff in major markets within the United States, Canada, Europe, Japan, China, Singapore, South

Korea, Taiwan, Vietnam, and other Asia-Pacific countries. This organization works closely with customers, customer groups and independent
representatives in servicing equipment, training customers to use our products and exploring additional applications of our technologies.

We typically provide parts and service warranties on our lasers, laser-based systems, optical and laser components and related accessories and services.

The length of warranties offered on our products and services varies, but primarily ranges from 12 to 24 months. Warranty reserves, as reflected on our
consolidated balance sheets, have generally been sufficient to cover product warranty repair and replacement costs. The weighted average warranty period
covered in our reserve is approximately 15 to 18 months.

MANUFACTURING

Since the acquisition of Rofin in fiscal 2017, we have implemented strategies to improve operating leverage, to execute synergies and to enhance our
customers' experience. For example, in June 2019, we announced our plans to exit a portion of our HPFL business and consolidate all HPFL manufacturing
and engineering functions in our Tampere, Finland facility by

19

transferring certain HPFL activities from our Hamburg, Germany facility. In fiscal 2020, we reorganized our reporting structure so that all business units
now report to our Executive Vice President and Chief Operating Officer. Common policies and guidelines have been communicated, key management and
operating processes have been implemented and ERP systems deployed at Rofin's sites in Asia, North America, and Europe, including all significant
manufacturing sites, consistent with the rest of Coherent.

Strategies

One of our core manufacturing strategies is to tightly control our supply of key parts, components, sub-assemblies, and outsourcing partners. We utilize
vertical integration when we have proprietary internal capabilities that are not cost-effectively available from external sources. We believe this is essential to
maintaining high quality products and enable rapid development and deployment of new products and technologies. We are committed to providing
customers with products manufactured at the highest level of quality and reliability by continuously improving our quality management system and adhering
to processes that are International Organization for Standardization ("ISO") certified at our principal manufacturing sites.

Our commitment to Operational Excellence and continuous improvement is at the core of our Coherent Lean culture aimed at creating value for our

customers. Our culture of continuous improvement is driven throughout all operations by embracing and developing a common culture of learning. Our
passion for operational excellence is embedded in all operations by continually teaching our teams how to identify waste, leveraging proven problem solving
tools, standardizing our manufacturing systems and empowering our employees to drive change through best practice sharing or Kaizen events.

Committed to quality and customer satisfaction, we design and produce many of our own components and sub-assemblies in order to retain quality and

performance control. We have also outsourced certain components, sub-assemblies and finished goods where we can maintain our high quality standards
while improving our cost structure.

As part of our strategy to increase our market share and customer support in Asia as well as our continuing efforts to manage costs, we continue to

transfer the production of targeted products to our Singapore and Malaysia factories. Our increased tube refurbishment capacity in our South Korea
operations has allowed us to reduce service response time, carry strategic inventory, and provide benefits to us and to our customers throughout the APAC
region. Our Asia material sourcing strategy driven by our International Procurement Office in Singapore continues to expand, which has enabled us to
leverage spend and reduce material costs on a global basis.

We have designed and implemented proprietary manufacturing tools, equipment and techniques in an effort to provide products that differentiate us
from our competitors. These proprietary manufacturing techniques are utilized in a number of our product lines including our gas laser production, crystal
growth, beam alignment as well as the wafer growth for our semiconductor, optically pumped semiconductor laser product family and fiber component and
fiber laser product family.

Raw materials or sub-components required in the manufacturing process are generally available from several sources. However, we currently purchase

several key components and materials, including exotic materials, crystals and optics, used in the manufacture of our products from sole source or limited
source suppliers. We also purchase assemblies and turnkey solutions from contract manufacturers based on our proprietary designs. We rely on our own
production and design capability to manufacture and specify certain strategic components, crystals, fibers, semiconductor lasers, lasers and laser-based
systems.

For a discussion of the importance to our business of, and the risks attendant to sourcing, see "Risk Factors" in Item 1A — "We depend on sole source
or limited source suppliers, as well as on our own production capabilities, for some of the key components and materials, including exotic materials, certain
cutting-edge optics and crystals, used in our products, which makes us susceptible to supply shortages or price fluctuations that could adversely affect our
business, particularly our ability to meet our customers' delivery requirements."

Operations

Our products are manufactured at our sites in California, Oregon, Arizona, Michigan, New Jersey, Connecticut, and New Hampshire in the U.S.;
Germany, Scotland, Finland, Sweden, Switzerland, and Spain in Europe; and South Korea, China, Singapore, and Malaysia in Asia. In addition, we also use
contract manufacturers in southeast Asia, Eastern Europe and the United States for the production of certain assemblies and turnkey solutions.

Our ion gas lasers, a portion of our DPSS lasers that are used in microelectronics, scientific research and materials processing applications,

Richmond, California manufactures high performance optical components and assemblies for the aerospace and defense industries as well as large form
optics for astronomical observatories and our own Linebeam excimer laser annealing systems. We manufacture fiber and free space Faraday rotators and
isolators critical to a wide range of lasers in Traverse City, Michigan. We manufacture and test high-power CO , solid-state and fiber laser macro products in
Hamburg, Germany; Plymouth, Michigan; East Granby, Connecticut; and Tampere, Finland. Our laser marking products are manufactured and tested in
Gilching, Germany and Singapore. Our micro application products are manufactured and tested in Gilching, Germany; Tampere, Finland; Plymouth,
Michigan; and Belp, Switzerland. Our diode laser products are manufactured and tested in Mainz and Freiburg, Germany. We completed the closure of our
Tucson, Arizona operation in the first half of fiscal 2021 and completed the closure of our Nanjing, China operation in the fourth quarter of fiscal 2021.
Anodization of our Slab laser electrodes is performed in Overath, Germany. Our fiber optics and beam delivery systems are manufactured and tested in
Molndal, Sweden. Our specialty fibers and fiber-based components for defense amplifiers and fiber optic gyroscopes are manufactured in East Granby,
Connecticut and Salem, New Hampshire. Optical engines for fiber lasers, fiber lasers modules and wafer material are designed and manufactured in
Tampere, Finland. We manufacture critical components for diode lasers in Monrovia, California.

2

We have transferred several products and sub-assemblies for manufacture and repairs to our Singapore and Malaysia facilities and are continuing to

transfer additional product manufacturing to these facilities as part of our worldwide manufacturing cost reduction strategy.

Coherent is committed to meeting internationally standards for the design, manufacture and service of products to industry-based requirements. All

primary facilities are certified to ISO 9001 whereas others hold multiple certifications based upon the markets they serve including ISO 13485, ISO 14001,
ISO 17025, ISO 45001 and/or ISO 50001.

INTELLECTUAL PROPERTY

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights.

As of October 2, 2021, we held approximately 890 U.S. and foreign patents, which expire in calendar years 2021 through 2040 (depending on the payment
of maintenance fees) and we have approximately 195 additional pending patent applications that have been filed. The issued patents cover various products
in all of the major markets that we serve.

Some of our products are designed to include intellectual property licensed from third parties. It may be necessary in the future to seek or renew
licenses relating to aspects of our products, processes and services. While we have generally been able to obtain such licenses on commercially reasonable
terms in the past, there is no guarantee that such licenses could be obtained on reasonable terms in the future or at all.

For a discussion of the importance to our business of, and the risks attendant to intellectual property rights, see "Risk Factors" in Item 1A — "If we are
unable to protect our proprietary technology, our competitive advantage could be harmed" and "We have been and may, in the future, be subject to claims or
litigation from third parties, for claims of infringement of their proprietary rights or to determine the scope and validity of our proprietary rights or the
proprietary rights of competitors or other rights holders. These claims could result in costly litigation and the diversion of our technical and management
personnel. Adverse resolution of litigation may harm our operating results or financial condition."

COMPETITION

Competition in the various photonics markets in which we provide products is very intense. We compete against a number of large public and private

companies including IPG Photonics Corporation, Lumentum Holdings Inc., MKS Instruments, Inc., Novanta Inc., nLIGHT, Inc., II-VI Incorporated, Wuhan
Raycus Fiber Laser Technologies Co., Ltd, and TRUMPF GmbH, as well as other smaller companies. In addition, from time to time our customers may also
decide to vertically integrate and build their own photonics products. We compete globally based on our broad product offering, reliability, cost, and
performance advantages for the widest range of commercial and scientific research applications. Other considerations by our customers include warranty,
global service and support and distribution.

21

BACKLOG

At fiscal 2021 year-end, our backlog of orders scheduled for shipment (within one year) was $717.1 million compared to $548.0 million at fiscal
2020 year-end. By segment, backlog for OLS was $426.0 million and $354.5 million at fiscal 2021 and 2020 year-ends, respectively. Backlog for ILS was
$291.1 million and $193.5 million at fiscal 2021 and 2020 year-ends, respectively. The increase in OLS backlog from fiscal 2020 to fiscal 2021 year-end
was primarily due to higher orders for excimer laser annealing systems for the flat panel display market as well as higher orders for service. The increase in
ILS backlog from fiscal 2020 to fiscal 2021 year-end was primarily due to higher orders in the precision manufacturing market. Orders used to compute
backlog are generally cancellable and, depending on the notice period, are subject to rescheduling by our customers. We have not historically experienced a
significant rate of cancellation or rescheduling, however the rate of cancellations or rescheduling may increase in the future. In the first quarter of fiscal
2019, one customer cancelled three purchase orders which included orders shippable within 12 months from fiscal 2018 year-end of $38.2 million and were
included in backlog as of fiscal 2018 year-end. We reached agreement with this customer for compensation for such cancellation in the first quarter of fiscal
2019.

SEASONALITY

We have historically generally experienced decreased revenue in the first fiscal quarter compared to other quarters in our fiscal year due to the impact

of time off and business closures at our facilities and those of many of our customers due to year-end holidays. For example, over the past 10 years,
excluding certain recovery years, our first fiscal quarter revenues have ranged 2%-17% below the fourth quarter of the prior fiscal years. This historical
pattern should not be considered a reliable indicator of the Company's future net sales or financial performance.

EMPLOYEES

Our workforce is distributed globally over 24 countries. As of fiscal 2021 year-end, we had approximately 5,085 employees worldwide, with

approximately 830 located in the Asia-Pacific region, 2,608 in the EMEA region, and 1,647 in the Americas region. Of our total workforce, approximately
640 employees are involved in research and development; 3,293 employees are involved in operations, manufacturing, service and quality assurance; and
1,152 employees are involved in sales, order administration, marketing, finance, information technology, general management and other administrative
functions. Our success will depend in large part upon our ability to attract and retain employees. We face competition in this regard from other companies,
research and academic institutions, government entities and other organizations. We consider our relations with our employees to be good.

Our human capital is governed by various federal, state and local regulations. We monitor all key employment activities, such as hiring, termination

and pay practices to ensure compliance with established regulations across the world. We embrace diversity and inclusion and strive to provide an
environment rich with diverse skills, backgrounds and perspectives. Within the United States we conduct a yearly review of employees and establish hiring
goals for minority, female, disabled and military veteran candidates. Our recruitment programs are regionally focused and hiring is done at a local level to
ensure compliance with specific regulations. To ensure diversity within our workforce we advertise job openings and source candidates broadly to attract a
diverse candidate pool. As a leader in our industry we are able to attract a strong candidate pool and have been successful in filing vacancies to ensure
business continuity. In fiscal 2021 we had 635 new hires, 280 of which were within the EMEA region, 282 of which were within the Americas region and 73
of which were in the Asia-Pacific region. During fiscal 2020, we also conducted a worldwide organizational health survey designed to assess employee
engagement, leadership, work environment and culture. We had a response rate of 77% of our total worldwide employee base, which is one indicator of a
high-level of employee engagement.

We track and report internally on key talent metrics including workforce demographics, talent pipeline, diversity data, and engagement of our

employees. We believe in investing in professional development programs to ensure we provide opportunities for individuals to advance their careers either
in a technical track or move to a leadership position. We offer many of our in-class training programs digitally so that more employees can benefit from self-
development during a period when many of our employees are working remotely. Additional focus is placed on the development of our future leaders and
we leverage a talent review process where high-potential and high-performing employees are assessed for future leadership roles as part of our succession
management process for critical leadership positions. As employee turnover is an indicator of employee satisfaction we closely monitor turnover globally
and benchmark locally. Coherent has a very stable and committed workforce. This translates into very low voluntary turnover when compared to benchmark
data. Our 12 month rolling average for voluntary turnover at the end of fiscal 2021 stood at 5.3%, substantially less than benchmark data. Our employee
average tenure globally is more than 10 years.

22

ACQUISITIONS

On April 19, 2021, we acquired EOT for approximately $29.3 million, excluding transaction costs. EOT is a specialized U.S.-based components

company, which we expect will enable us to vertically integrate and improve the performance of our directed energy amplifier technology.

On October 5, 2018, we acquired privately held Ondax for approximately $12.0 million, excluding transaction costs. Ondax develops and produces

photonic components which are used on an OEM basis by the laser industry as well as incorporated into its own stabilized lasers and Raman Spectroscopy
systems.

On October 5, 2018, we acquired certain assets of Quantum for approximately $7.0 million, excluding transaction costs.

Please refer to Note 4, "Business Combinations" of Notes to Consolidated Financial Statements under Item 8 of this annual report for further

discussion of recent acquisitions completed.

RESTRUCTURINGS AND CONSOLIDATION

In June 2019, we internally announced our plans to exit a portion of our HPFL business and consolidate all HPFL manufacturing and engineering

functions in our Tampere, Finland facility by transferring certain HPFL activities from our Hamburg, Germany facility. In conjunction with this
announcement, we recorded restructuring charges in fiscal 2019 of $19.7 million. The charges primarily related to write-offs of excess inventory, which is
recorded in cost of sales, and estimated severance. We recorded charges of $1.1 million in fiscal 2020, primarily related to accelerated depreciation and
project management consulting. We recorded no charges related to this project in fiscal 2021 as the project was completed in fiscal 2020.

We also vacated our leased facility in Santa Clara at the end of the lease term on July 31, 2020 and combined operations into our owned Santa Clara
headquarters. We did not incur material expenses in fiscal 2019 related to this project. In fiscal 2021 and 2020, we incurred costs of $0.1 million and $1.5
million, respectively, primarily related to accelerated depreciation and completed the project in fiscal 2021.

In the fourth quarter of fiscal 2020, we began a restructuring program in our ILS segment which includes management reorganizations, the planned

closure of multiple manufacturing sites, and the right-sizing of global sales, service, order admin, marketing communication and certain administrative
functions, among others. In the fourth quarter of fiscal 2020, we incurred costs of $2.6 million, primarily related to severance. In fiscal 2021, we incurred
costs of $12.2 million, primarily related to write-offs of excess inventory, accruals for vendor commitments and warranty provisions, which are recorded in
cost of sales, estimated severance, facility exit costs and accelerated depreciation.

See Note 19, "Restructuring Charges" in the Notes to Consolidated Financial Statements under Item 8 of this annual report.

GOVERNMENT REGULATION

We are required to comply, and it is our policy to comply, with numerous regulations that are normal and customary to businesses in our industry and

that operate in our markets and operating locations. These regulations relate to, among other things, healthcare, environmental protection, antitrust, anti-
corruption, marketing, fraud and abuse (including anti-kickback and false claims laws), export control, product safety and efficacy, employment, privacy,
governmental contracts and regulatory matters specific to the defense industry and other areas.

Environmental Regulation

Our operations are subject to various federal, state, local and foreign environmental regulations relating to the use, storage, handling and disposal of
regulated materials, chemicals, various radioactive materials and certain waste products. In the United States, we are subject to the federal regulation and
control of the Environmental Protection Agency. Comparable authorities are involved in other countries. We also face increasing complexity in our product
design and procurement operations due to the evolving nature of environmental compliance regulations and standards, as well as specific customer
compliance requirements. We expect all operations to meet the legal and regulatory environmental requirements and believe that compliance with those
regulations will not have a material adverse effect on our capital expenditures, earnings and competitive and financial position.

Although we believe that our safety procedures for using, handling, storing and disposing of such materials comply with the standards required by

federal and state laws and regulations, we cannot completely eliminate the risk of accidental contamination or injury from these materials. In the event of
such an accident involving such materials, we could be liable for damages and such liability could exceed the amount of our liability insurance coverage and
the resources of our business.

23

We further discuss the impact of environmental regulation under "Risk Factors" in Item 1A — "Compliance or the failure to comply with current and

future environmental regulations could cause us significant expense."

Regulatory Compliance

Lasers that are manufactured or sold in the United States are classified under the applicable rules and regulations of the Center for Devices and

Radiological Health ("CDRH") of the U.S. Food and Drug Administration ("FDA"). A similar classification system is applied in the European markets.

CDRH regulations require a self-certification procedure pursuant to which a manufacturer must submit a filing to the CDRH with respect to each
product incorporating a laser, make periodic reports of sales and purchases, and comply with product labeling standards, product safety and design features
and informational requirements. The CDRH is empowered to seek fines and other remedies for violations of their requirements. We believe that our products
are in material compliance with the applicable rules and regulations of CDRH relating to lasers manufactured or sold in the United States.

In addition, certain portions of our business contract with numerous U.S. government agencies and entities or with entities whose projects are funded

therefrom. We also contract with similar government authorities outside of the U.S., subject in all cases to applicable law. Consequently, we must comply
with and are affected by regulations relating to the formation, administration, and performance of such U.S. government and other contracts governing such
matters.

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 prior to any export, re-export, or deemed export. Certain of our products are subject to the EAR and/or the ITAR.
Products and the associated technical data developed and manufactured in our foreign locations are subject to export controls of the applicable foreign
nation. We further discuss the impact of such regulations under "Risk Factors" in Item 1A – "Governmental regulations, including tariffs and duties,
affecting the import or export of products could negatively affect our business, financial condition and results of operations."

We are subject to laws concerning our business operations and marketing activities in foreign countries where we conduct business. For example, we

are subject to the U.S. Foreign Corrupt Practices Act (the "FCPA"), U.S. export control and trade sanction laws, and similar anti-corruption and international
trade laws in certain foreign countries, such as the U.K. Bribery Act. We further discuss the impact of such regulations under "Risk Factors" in Item 1A –
"Violations of anti-bribery, anti-corruption, and/or international trade laws to which we are subject could negatively affect our business, financial condition
and results of operations."

Aspects of our operations and business are subject to privacy, data security and data protection regulations, which impact the way we use and handle

data and operate our products and services. We further discuss the impact of such regulations under "Risk Factors" in Item 1A – "We may face particular
privacy, data security and data protection risks due to laws and regulations regulating the protection or security of personal and other sensitive data."

24

ITEM 1A. RISK FACTORS

You should carefully consider the followings risks when considering an investment in our common stock. These risks could materially affect our
business, results of operations or financial condition, cause the trading price of our common stock to decline materially or cause our actual results to differ
materially from those expected or those expressed in any forward-looking statements made by us. These risks are not exclusive, and additional risks to which
we are subject include, but are not limited to, the factors mentioned under "Forward-Looking Statements" and the risks described elsewhere in this annual
report. Additionally, these risks and uncertainties described herein are not the only ones facing us. Other events that we do not currently anticipate or that
we currently deem immaterial also may affect our business, results of operations or financial condition.

RISKS RELATED TO OUR PENDING MERGER WITH II-VI

Our pending merger with II-VI may be delayed or not occur at all for a variety of reasons, including the possibility that the II-VI Merger Agreement is
terminated or expires prior to the consummation of the acquisition.

On March 25, 2021, we entered into the II-VI Merger Agreement, pursuant to which we agreed to be acquired for $220.00 in cash per Coherent share

and 0.91 of a share of II-VI common stock per Coherent share. On June 24, 2021, II-VI and Coherent held special meetings of their shareholders and
stockholders, respectively, at which all proposals relating to the II-VI Merger Agreement were approved.

Completion of the Merger is subject to customary closing conditions, including (i) the absence of certain legal impediments and (ii) regulatory
approvals in applicable jurisdictions including the United States, Germany, China and South Korea. Many of the conditions to completion of the Merger are
not within either our or II-VI's control, and we cannot predict when or if these conditions will be satisfied (or waived, as applicable).

The II-VI Merger Agreement contains customary mutual termination rights for us and II-VI, including if the Merger is not completed by December 25,

2021 (subject to automatic extension first to March 25, 2022, then to June 25, 2022 and finally to September 25, 2022, in each case, to the extent the
regulatory closing conditions remain outstanding).

The II-VI Merger Agreement also contains customary termination rights for the benefit of each party, including if the other party breaches its
representations, warranties or covenants under the II-VI Merger Agreement in a way that would result in a failure of the other party's condition to closing
being satisfied (subject to certain procedures and cure periods).

In light of the foregoing, the Merger may not be completed or may not be completed as quickly as expected.

Failure to complete the Merger could adversely affect our business and the market price of our common stock in a number of ways, including:

•

the market price of our common stock may decline to the extent that the current market price reflects an assumption that the Merger will be
consummated;

• we paid a termination fee of $217.6 million to Lumentum in connection with the termination of the Amended Lumentum Agreement for which we

will have received little or no benefit if the Merger is not consummated;

• we have incurred, and will continue to incur, significant expenses for professional services in connection with the Merger for which we will have

received little or no benefit if the Merger is not consummated;

• we have incurred significant expenses, including the costs of settlement, in connection with litigation against us and our directors and officers in

connection with the Merger for which we will have received little or no benefit if the Merger is not consummated; and

•

failure to consummate the Merger may result in negative publicity and/or give a negative impression of us in the investment community or business
community generally.

The Merger could divert management's attention, disrupt our relationships with third parties and employees and result in negative publicity or legal
proceedings, any of which could negatively impact our operating results and ongoing business.

We have expended, and continue to expend, significant management time and resources in an effort to complete the Merger, which may have a
negative impact on our ongoing business. Uncertainty regarding the outcome of the Merger and our future could disrupt our business relationships with our
existing and potential customers, suppliers, vendors, landlords and other business partners, who may attempt to negotiate changes in existing business
relationships or consider entering into business relationships with parties other than us. Uncertainty regarding the outcome of the Merger could also
adversely affect our ability to recruit and retain key personnel and other employees. The pendency of the Merger may also result in negative publicity and a

25

negative impression of us in the financial markets, and has resulted in, and may result in additional, litigation against us and our directors and officers. Such
litigation may be distracting to management and has required us to incur, and may require us to incur additional, significant costs. Such litigation could
result in the Merger being delayed and/or enjoined by a court of competent jurisdiction, which could prevent the Merger from becoming effective. The
occurrence of any of these events individually or in combination could have a material and adverse effect on our business, financial condition and results of
operations.

While the II-VI Merger Agreement is in effect, we are subject to certain interim covenants.

While the II-VI Merger Agreement is in effect, we are subject to customary interim operating covenants and must generally operate our business in the

ordinary course, subject to certain exceptions. These restrictions could prevent us from pursuing certain business opportunities that may arise prior to the
consummation of the Merger. The interim operating covenants require us to obtain II-VI's consent (such consent not to be unreasonably conditioned,
withheld or delayed) prior to taking certain actions, which requirement could significantly impact our operating results and ongoing business.

After the Merger, our stockholders will have a significantly lower ownership and voting interest in II-VI than they currently have in Coherent and will
exercise less influence over management.

Coherent and II-VI estimate that, as of immediately following completion of the Merger, holders of Coherent common stock immediately prior to the

Merger will hold approximately 14% of the combined company (based on fully diluted shares outstanding of the combined company as of September 30,
2021). Consequently, former Coherent stockholders will have less influence over the management and policies of II-VI than they currently have over the
management and policies of Coherent.

The rights of our stockholders will change as a result of the Merger.

The rights of Coherent stockholders are governed by Delaware law and by the charter and bylaws of Coherent. If the Merger is completed, Coherent

stockholders will become holders of II-VI common stock, and their rights will be governed by Pennsylvania law and the charter and bylaws of II-VI.
Coherent stockholders will, therefore, have different rights after becoming II-VI stockholders due to differences in governing law and between the Coherent
governing documents and the II-VI governing documents.

After completion of the Merger, II-VI may fail to realize the anticipated benefits and cost savings of the Merger, which could adversely affect the value
of II-VI common stock.

The success of the Merger will depend, in part, on II-VI's ability to realize the anticipated benefits and cost savings from combining the businesses of
II-VI and Coherent. The anticipated benefits and cost savings of the Merger may not be realized fully or at all, may take longer to realize than expected or
could have other adverse effects that we do not currently foresee. The integration process may, for us and II-VI, result in the loss of key employees, the
disruption of ongoing businesses or inconsistencies in standards, controls, procedures and policies. There could be potential unknown liabilities and
unforeseen expenses associated with the Merger that were not discovered in the course of performing due diligence.

Additionally, the integration will require significant time and focus from management following the acquisition which may disrupt the business of the

combined company.

RISKS RELATED TO COVID-19 PANDEMIC

Our business, financial condition and results of operations may be materially adversely affected by the COVID-19 pandemic and the related private and
public sector responses to the pandemic.

The full extent to which the COVID-19 pandemic could impact our financial condition and operating results will depend on future developments that
are highly uncertain and cannot be accurately predicted, including COVID-19 infections intensifying or returning in various geographic areas, the severity
and transmission rate of variants of the virus, new medical and other information that may emerge concerning COVID-19, the effectiveness of vaccines, and
the actions by governmental entities or others to address it, contain it or treat its impact.

COVID-19 poses the risk that we or our employees, suppliers, distributors, customers and others may be restricted or prevented from conducting

business activities for indefinite or intermittent periods of time, including as a result of employee health and safety concerns, shutdowns, shelter-in-place
("SiP") orders, travel restrictions and other actions and restrictions that may be prudent or required by governmental authorities. Even after governmental
entities have lifted SiP orders, there is a risk that such orders will be reinstated, making it difficult to predict the long term financial impact of this virus on
the Company. Examples of this have been seen across the globe, including most recently in continuing actions and guidance provided by the U.S. and
European governments.

26

To date, many (but not all) of our business operations and those of our suppliers, distributors and customers have been classified as essential or
otherwise permitted to operate in jurisdictions in which facility closures have been mandated; however, we can give no assurance that this will not change in
the future or that we, our suppliers, distributors and customers will continue to be permitted to conduct business in each of the jurisdictions in which we
operate.

In addition, we have modified our business practices for the continued health and safety of our employees - including, among other things,

implementing a remote work policy to the fullest extent possible, a limited travel policy, the distribution of and mandatory wearing of personal protection
equipment, reorganizing and adjusting the timing of manufacturing personnel shifts, temperature monitoring for entering our facilities, and a social
distancing policy - and we may take further actions, or be required to take further actions, that are in the best interests of our employees. Our suppliers,
distributors and customers have also implemented such measures, which has resulted in, and we expect it will continue to result in, disruptions or delays and
higher costs. The implementation of health and safety practices by us or our suppliers, distributors or customers could impact customer demand, supplier
deliveries, our productivity, and costs, which could have a material adverse impact on our business, financial condition and results of operations.

While we currently believe we have sufficient liquidity to manage the financial impact of the COVID-19 pandemic, we can give no assurance that this
will continue to be the case if the pandemic is prolonged or if there is an extended impact on us or the economy generally. Further, the pandemic has caused
significant uncertainty and volatility in the credit markets. If our liquidity or access to capital becomes significantly constrained, or if costs of capital
increase significantly as result of volatility in the capital markets, a reduction in our creditworthiness or other factors, then our financial condition, results of
operations and cash flows could be materially adversely affected.

We have invested and will continue to invest significant time and resources in managing the impact of the COVID-19 pandemic on our business. Our

focus on managing and mitigating such impact may cause us to divert or delay the application of resources toward existing or new initiatives or investments,
which could have a material adverse impact on our results of operations.

Please refer to "Coronavirus pandemic (COVID-19)" under "Significant Events" in "Item 7. Management’s Discussion and Analysis of Financial

Condition and Results of Operations" for additional discussion of the risks related to the COVID-19 pandemic and its impact on the Company.

COMPANY AND OPERATIONAL RISKS

Our operating results and stock price have varied in the past and will continue to be subject to fluctuations in the future based upon numerous factors,
including those discussed in this Item 1A and throughout this report.

Our operating results, including net sales, operating expenses, net income (loss) and adjusted EBITDA in dollars and as a percentage of net sales, as
well as our stock price, have varied in the past and may vary significantly from quarter to quarter and from year to year in the future. We believe a number of
factors, many of which are outside of our control, could cause these variations and make them difficult to predict, including:

•

•

•

•

•

•

•

general economic uncertainties in the macroeconomic and local economies facing us, our customers and the markets we serve, particularly as
COVID-19 continues to adversely affect the global economy;

impact of government economic policies on macroeconomic conditions, such as recently instituted, proposed or threatened changes in trade policies
by the U.S. and any corresponding retaliatory actions by affected countries, in particular with respect to China, as well as trade restrictions
instituted by the Japanese government affecting the export to South Korea of certain products and materials used in the manufacture of flat panel
displays and in the semiconductor industry;

fluctuations in demand for our products or downturns in the industries that we serve, particularly the continued build-out of "phase 2" of the
capacity for the manufacture of OLED and the increased use of the installed base of our products in such manufacturing;

the ability of our suppliers, both internal and external, to produce and deliver components and parts, including sole or limited source components, in
a timely manner, in the quantity, quality and prices desired;

the timing of receipt of bookings and the timing of and our ability to ultimately convert bookings to net sales;

the concentration of a significant amount of our backlog, and resultant net sales, with a few customers in the Microelectronics market;

rescheduling of shipments or cancellation of orders by our customers;

interpretation and impact of the U.S. Tax Cuts and Jobs Act ("the Tax Act") and the Coronavirus Aid, Relief, and Economic Security Act (the
"CARES Act") and any additional related newly enacted laws;

introductions of new products and product enhancements by our competitors, entry of new competitors into our markets, pricing pressures and
other competitive factors;

the increasing focus by companies in China to vertically integrate and consolidate their supply chains fully with products manufactured in China;

our ability to develop, introduce, manufacture and ship new and enhanced products in a timely manner without defects;

our ability to manage our manufacturing capacity across our diverse product lines and that of our suppliers, including our ability to successfully
expand our manufacturing capacity in various locations around the world;

our ability to successfully and fully integrate acquisitions, into our operations and management;

our ability to successfully internally transfer the manufacturing of products and related operations as part of our integration and internal
reorganization efforts and to realize anticipated benefits (including savings) therefrom;

our reliance on contract manufacturing;

our reliance in part upon the ability of our OEM customers to develop and sell systems that incorporate our laser products;

our customers' ability to manage their susceptibility to adverse economic conditions;

the rate of market acceptance of our new products;

the ability of our customers to pay for our products;

expenses associated with acquisition-related activities, including the costs of acquiring businesses or technologies;

seasonal sales trends;

jurisdictional capital and currency controls negatively impacting our ability to move funds from or to an applicable jurisdiction;

access to applicable credit markets by us, our customers and their end customers;

delays or reductions in customer purchases of our products in anticipation of the introduction of new and enhanced products by us or our
competitors;

our ability to control expenses;

the level of capital spending of our customers;

potential excess and/or obsolescence of our inventory;

costs and timing of adhering to current and developing governmental regulations and reviews relating to our products and business, including
import and export regulations in multiple jurisdictions;

impairment of goodwill, intangible assets and other long-lived assets;

28

•

continued government spending on defense-related and scientific research projects where we are a vendor or subcontractor;

• maintenance of supply relating to products sold to the government on terms which we would prefer not to accept;

•

•

•

•

changes in policy, interpretations, or challenges to the allowability of costs incurred under government cost accounting standards;

changes in the method of determining the London Interbank Offered Rate ("LIBOR"), the Euro Interbank Offered Rate ("EURIBOR"), or the
replacement of LIBOR or EURIBOR with an alternative reference rate, may adversely affect interest rates on our outstanding variable rate
indebtedness;

our ability and the ability of our contractual counterparts to comply with the terms of our contracts;

damage to our reputation as a result of coverage in social media, Internet blogs or other media outlets;

• managing our and other parties' compliance with contracts in multiple languages and jurisdictions;

• managing our internal and third party sales representatives and distributors, including compliance with all applicable laws;

•

•

•

•

•

•

•

•

•

costs, expenses and damages arising from litigation;

the impact of market fluctuations on assets and liabilities in our deferred compensation plans;

costs associated with designing around or payment of licensing fees associated with issued patents in our fields of business;

individual employees intentionally or negligently failing to comply with our internal controls;

government support of alternative energy industries, such as solar;

negative impacts related to the United Kingdom's withdrawal from the European Union, or "Brexit", including uncertainties regarding the terms of
applicable trade treaties between the United Kingdom and other countries, particularly with regard to any potential negative effects on our sales
from our Glasgow, Scotland facility to other jurisdictions and purchases of supplies from outside the United Kingdom by such facility;

negative impacts related to government instability in any jurisdiction in which we operate;

the future impact of legislation, rulemaking, and changes in accounting, tax, defense procurement and export policies; and

distraction of management related to acquisition, integration or divestment activities.

In addition, we often recognize a substantial portion of our sales in the last month of our fiscal quarters. Our expenses for any given quarter are
typically based on expected sales, and if sales are below expectations in any given quarter, the adverse impact of the shortfall on our operating results may
be magnified by our inability to adjust spending quickly enough to compensate for the shortfall. We also base our manufacturing on our forecasted product
mix for the quarter. If the actual product mix varies significantly from our forecast, we may not be able to fill some orders during that quarter, which would
result in delays in the shipment of our products. Accordingly, variations in timing of sales, particularly for our higher priced, higher margin products, can
cause significant fluctuations in quarterly operating results.

Due to these and other factors, we believe that quarter-to-quarter and year-to-year comparisons of our historical operating results may not be

meaningful. You should not rely on our results for any quarter or year as an indication of our future performance. Our operating results in future quarters and
years may be below public market analysts' or investors' expectations, which would likely cause the price of our stock to fall. In addition, over the past
several years, U.S. and global equity markets have experienced significant price and volume fluctuations that have affected the stock prices of many
technology companies both in and outside our industry, and the ongoing COVID-19 pandemic could exacerbate such fluctuations. There has not always
been a direct correlation between this volatility and the performance of particular companies subject to these stock price fluctuations. These factors, as well
as general economic and political conditions or investors' concerns regarding the credibility of corporate financial statements, may have a material adverse
effect on the market price of our stock in the future.

We depend on sole source or limited source suppliers, as well as on our own production capabilities, for some of the key components and materials,
including exotic materials, certain cutting-edge optics and crystals, aluminum, and magnesium,

29

used in our products, which makes us susceptible to supply shortages or price fluctuations that could adversely affect our business, particularly our
ability to meet our customers' delivery requirements.

We currently purchase several key components and materials used in the manufacture of our products from sole source or limited source suppliers.
From time-to-time our customers require us to ramp up production and/or accelerate delivery schedules of our products, and our key suppliers may not have
the ability to increase their production in line with our customers' demands. This can become acute during times of high growth in our customers' businesses.
Our failure to timely receive these key components and materials would likely cause delays in the shipment of our products, which would likely negatively
impact both our customers and our business. Some of these suppliers are relatively small private companies that may discontinue their operations at any time
and may be particularly susceptible to prevailing economic conditions. Some of our suppliers are located in regions susceptible to natural and man-made
disasters, such as Thailand which has experienced severe flooding, Japan which has experienced earthquakes, tsunamis and a resulting nuclear disaster, and
the Eastern part of the United States, California, Belgium and Germany, which have experienced severe flooding, wildfires and/or power loss. In addition,
our suppliers have been adversely affected by the COVID-19 pandemic and the related imposition of government restrictions to mitigate the spread of the
virus. We typically purchase our components and materials through purchase orders or agreed upon terms and conditions, and we do not have guaranteed
supply arrangements with many of these suppliers. For certain long-lead time supplies or in order to lock-in pricing, we may be obligated to place non-
cancellable purchase orders or otherwise assume liability for a large amount of the ordered supplies, which limits our ability to adjust down our inventory
liability in the event of market downturns or other customer cancellations or rescheduling of their purchase orders for our products.

Some of our products, particularly in the flat panel display industry, require designs and specifications that are at the cutting-edge of available
technologies and change frequently to meet rapidly evolving market demands. By their very nature, the types of components used in such products can be
difficult and unpredictable to manufacture and may only be available from a single supplier, which increases the risk that we may not obtain such
components in a timely manner. Identifying alternative sources of supply for certain components could be difficult and costly, result in management
distraction in assisting our current and future suppliers to meet our and our customers' technical requirements, and cause delays in shipments of our products
while we identify, evaluate and test the products of alternative suppliers. Any such delay in shipment would result in a delay or cancellation of our ability to
convert such order into revenues. Furthermore, financial or other difficulties faced by these suppliers or significant changes in demand for these components
or materials could limit their availability. We continue to consolidate our supply base and move supplier locations. When we transition locations, we may
increase our inventory of such products as a "safety stock" during the transition, which may cause the amount of inventory reflected on our balance sheet to
increase. Additionally, many of our customers rely on sole source suppliers. In the event of a disruption of our customers' supply chain, orders from our
customers could decrease or be delayed.

Like most other multinational companies, we are also highly dependent upon the ability to ship products to customers and to receive shipments of
supplies from suppliers. The COVID-19 pandemic and resulting government policies have resulted in variable limitations on our ability to receive supplies
and ship our products to customers. In the event of a disruption in the worldwide or regional shipping infrastructure, our access to supplies and our ability to
deliver products to customers would correspondingly be negatively impacted. Any such disruption would likely materially and adversely affect our
operating results and financial condition.

Any interruption or delay in the supply of any of these components or materials, or the inability to obtain these components and materials from
alternate sources at acceptable prices and within a reasonable amount of time, or our failure to properly manage these moves, would impair our ability to
meet scheduled product deliveries to our customers and could cause customers to cancel orders. Furthermore, we have historically relied exclusively on our
own production capability to manufacture certain strategic components, crystals, semiconductor lasers, fiber, lasers and laser-based systems. We also
manufacture certain large format optics. Because we manufacture, package and test these components, products and systems at our own facilities, and such
components, products and systems are not readily available from other sources, any interruption in manufacturing would adversely affect our business. Since
many of our products have lengthy qualification periods, our ability to introduce multiple suppliers for parts may be limited. In addition, our failure to
achieve adequate manufacturing yields of these items at our manufacturing facilities may materially and adversely affect our operating results and financial
condition.

Disruption in our global supply chain could negatively impact our businesses.

The products we sell are sourced from a wide variety of domestic and international vendors, and any future disruption in our supply chain or inability

to find qualified vendors and access products that meet requisite quality and safety standards in a timely and efficient manner could adversely impact our
businesses. The loss or disruption of such supply arrangements for any reason, including for issues such as COVID-19 or other health epidemics or
pandemics, labor disputes, loss or impairment of key manufacturing sites, inability to procure sufficient raw materials, quality control issues, ethical
sourcing issues, a supplier’s financial distress, natural disasters, looting, vandalism or acts of war or terrorism, trade sanctions or other external factors over

30

which we have no control, could interrupt product supply and, if not effectively managed and remedied, have a material adverse impact on our business
operations, financial condition and results of operations.

We participate in the microelectronics market, which requires significant research and development expenses to develop and maintain products and a
failure to achieve market acceptance for our products could have a significant negative impact on our business and results of operations.

The microelectronics market is characterized by rapid technological change, frequent product introductions, the volatility of product supply and
demand, changing customer requirements and evolving industry standards. The nature of this market requires significant research and development expenses
to participate, with substantial resources invested in advance of material sales of our products to our customers in this market. Additionally, our product
offerings may become obsolete given the frequent introduction of alternative technologies. In the event either our customers' or our products fail to gain
market acceptance, or the microelectronics market fails to grow, it would likely have a significant negative effect on our business and results of operations.

We participate in the flat panel display market, which has a relatively limited number of end customer manufacturers. Our backlog, timing of net sales
and results of operations could be negatively impacted in the event we face any significant periods with few or no orders or our customers reschedule or
cancel orders.

In the flat panel display market, it is unclear when the timing will be, or whether it will occur at all, for any further build-out of fabs for the

manufacture of OLED screens, and there are a relatively limited number of manufacturers who are the end customers for our annealing products. In fiscal
2021, Advanced Process Systems Corporation, an integrator in the flat panel display market based in South Korea, contributed more than 10% of our
revenue. Given macroeconomic conditions, varying consumer demand and technical process limitations at manufacturers, we may see fluctuations in orders,
including periods with no or few orders, and our customers may seek to reschedule or cancel orders. For example, in the first quarter of fiscal 2019, one
customer cancelled three purchase orders which included backlog shippable within 12 months of $38.2 million as well as some additional orders which were
unscheduled.

These larger flat panel-related systems have large average selling prices. Any significant periods with few or no orders or any rescheduling or

canceling of such orders by our customers will likely have a significant impact on our quarterly or annual net sales and results of operations and could
negatively impact inventory values and backlog. Additionally, challenges in meeting evolving technological requirements for these complex products by us
and our suppliers could result in delays in shipments and rescheduled or cancelled orders by our customers. This could negatively impact our backlog,
timing of net sales and results of operations.

Some of our laser systems are complex in design and may contain defects that are not detected until deployed by our customers, which could increase
our costs and reduce our net sales.

Lasers and laser systems are inherently complex in design and require ongoing regular maintenance. The manufacture of our lasers, laser products and

laser systems involves a highly complex and precise process. As a result of the technological complexity of our products, in particular our excimer laser
annealing tools used in the flat panel display market, changes in our or our suppliers' manufacturing processes or the inadvertent use of defective materials
by us or our suppliers could result in a material adverse effect on our ability to achieve acceptable manufacturing yields and product reliability. To the extent
that we do not achieve and maintain our projected yields or product reliability, our business, operating results, financial condition and customer relationships
would be adversely affected. We provide warranties on a majority of our product sales, and reserves for estimated warranty costs are recorded during the
period of sale. The determination of such reserves requires us to make estimates of failure rates and expected costs to repair or replace the products under
warranty. We typically establish warranty reserves based on historical warranty costs for each product line. If actual return rates and/or repair and
replacement costs differ significantly from our estimates, adjustments to cost of sales may be required in future periods which could have an adverse effect
on our results of operations.

Our customers may discover defects in our products after the products have been fully deployed and operated, including under the end user's peak
stress conditions. In addition, some of our products are combined with products from other vendors, which may contain defects. As a result, should problems
occur, it may be difficult to identify the source of the problem. If we are unable to identify and fix defects or other problems, we could experience, among
other things:

•

•

•

•

loss of customers or orders;

increased costs of product returns and warranty expenses;

damage to our brand reputation;

failure to attract new customers or achieve market acceptance;

31

•

•

diversion of development, engineering and manufacturing resources; and

legal actions by our customers and/or their end users.

The occurrence of any one or more of the foregoing factors could seriously harm our business, financial condition and results of operations.

Continued volatility in the advanced packaging and semiconductor manufacturing markets could adversely affect our business, financial condition and
results of operations.

A portion of our net sales in the microelectronics market depends on the demand for our products by advanced packaging applications and

semiconductor equipment companies. These markets have historically been characterized by sudden and severe cyclical variations in product supply and
demand, which have often severely affected the demand for semiconductor manufacturing equipment, including laser-based tools and systems. The timing,
severity and duration of these market cycles are difficult to predict, especially during the ongoing COVID-19 pandemic, and we may not be able to respond
effectively to these cycles. The continuing uncertainty in these markets severely limits our ability to predict our business prospects or financial results in
these markets.

During industry downturns, our net sales from these markets may decline suddenly and significantly. Our ability to rapidly and effectively reduce our

cost structure in response to such downturns is limited by the fixed nature of many of our expenses in the near term and by our need to continue our
investment in next-generation product technology and to support and service our products. In addition, due to the relatively long manufacturing lead times
for some of the systems and subsystems we sell to these markets, we may incur expenditures or purchase raw materials or components for products we
cannot sell. Accordingly, downturns in the semiconductor capital equipment market may materially harm our operating results. Conversely, when upturns in
these markets occur, we must be able to rapidly and effectively increase our manufacturing capacity to meet increases in customer demand that may be
extremely rapid, and if we fail to do so we may lose business to our competitors and our relationships with our customers may be harmed.

Our future success depends on our ability to increase our sales volumes and decrease our costs to offset potential declines in the average selling prices of
our products and, if we are unable to realize greater sales volumes and lower costs, our operating results may suffer.

Our ability to increase our sales volume and our future success depends on the continued growth of the markets for lasers, laser systems, laser

components and related accessories, as well as our ability to identify, in advance, emerging markets for laser-based systems and to manage our
manufacturing capacity to meet customer demands. We cannot assure you that we will be able to successfully identify, on a timely basis, new high-growth
markets in the future. Moreover, we cannot assure you that new markets will develop for our products or our customers' products, or that our technology or
pricing will enable such markets to develop. Future demand for our products is uncertain and will depend to a great degree on continued technological
development and the introduction of new or enhanced products. If this does not continue, sales of our products may decline and our business will be harmed.

We have in the past experienced decreases in the average selling prices ("ASPs") of some of our products. As competing products become more widely

available or lower-cost products come to market, the ASPs of our products may decrease. If we are unable to offset any decrease in our ASPs by increasing
our sales volumes, our net sales will decline. In addition, to maintain our gross margins, we must continue to reduce the cost of manufacturing our products
while maintaining their high quality. From time to time, our products, like many complex technological products, may fail in greater frequency than
anticipated. This can lead to further charges, which can result in higher costs, lower gross margins and lower operating results. Furthermore, as ASPs of our
current products decline, we must develop and introduce new products and product enhancements with higher margins. If we cannot maintain our gross
margins, our operating results could be seriously harmed, particularly if the ASPs of our products decrease significantly.

We face risks associated with our worldwide operations and sales that could harm our financial condition and results of operations.

For fiscal 2021, 2020 and 2019, 77%, 76%, and 76%, respectively, of our net sales were derived from customers outside of the United States. We

anticipate that international sales, particularly in Asia, will continue to account for a significant portion of our net sales in the foreseeable future.

A global economic slowdown or a natural disaster could have a negative effect on various international markets in which we operate, such as the

earthquake, tsunami and resulting nuclear disaster in Japan and the flooding in Germany and Thailand. Such a slowdown may cause us to reduce our
presence in certain countries, which may negatively affect the overall level of business in such countries. Our international sales are primarily through our
direct sales force. Additionally, some international

32

sales are made through international distributors and representatives. Currently, the COVID-19 pandemic is having a significant adverse effect on the global
economy, which is affecting the various markets in which we operate.

Our international operations and sales are subject to a number of risks, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

compliance with applicable import/export regulations, tariffs and trade barriers, including recently instituted or proposed changes in trade policies
by the U.S. and any corresponding retaliatory actions by affected countries, in particular with respect to China;

longer accounts receivable collection periods;

the impact of recessions and other economic conditions in economies outside the United States, including, for example, dips in the manufacturing
Purchasing Managers Index as well as the Institute for Supply Management data in the Eurozone, in particular in Germany;

unexpected changes in regulatory requirements and compliance with applicable regulatory requirements;

product certification requirements;

environmental regulations;

reduced protection for intellectual property rights in some countries;

potentially adverse tax consequences;

political and economic instability, such as the current situation between the governments of Japan and South Korea, which has led to the imposition
of trade restrictions by the Japanese government affecting the export to South Korea of certain products and materials used in the manufacture of
flat panel displays and in the semiconductor industry;

compliance with applicable United States and foreign anti-corruption laws;

less than favorable contract terms;

reduced ability to enforce contractual obligations;

cultural and management differences;

reliance in some jurisdictions on third party sales channel partners;

preference for locally produced products; and

shipping and other logistics complications.

Our business could also be impacted by international conflicts, terrorist and military activity including, in particular any such conflicts on the Korean

peninsula, civil unrest and pandemics, any of which could cause a slowdown in customer orders, cause customer order cancellations or negatively impact
availability of supplies or limit our ability to timely service our installed base of products.

We are also subject to the risks of fluctuating foreign currency exchange rates, which could materially adversely affect the sales price of our products

in foreign markets, as well as the costs and expenses of our international subsidiaries, particularly if we have a significant amount of manufacturing costs
denominated in one currency (e.g. the Euro) compared to the sales of those same products to customers denominated in another currency (e.g. the U.S.
Dollar). While we use forward exchange contracts and other risk management techniques to hedge our foreign currency exposure, we remain exposed to the
economic risks of foreign currency fluctuations.

We depend on skilled personnel to operate our business effectively in a rapidly changing market, and if we are unable to retain existing or hire
additional personnel when needed, or manage transitions among members of our leadership team, our ability to develop and sell our products could be
harmed.

Our ability to continue to attract and retain highly skilled personnel will be a critical factor in determining whether we will be successful in the future,

including the time preceding the closing of the Merger. Recruiting and retaining highly skilled personnel in certain functions continues to be difficult. At
certain locations where we operate, the cost of living is extremely high and it may be difficult to retain key employees and management at a reasonable cost.
We may not be successful in attracting, assimilating or retaining qualified personnel to fulfill our current or future needs, which could adversely affect our
growth and our business.

33

Our future success depends upon the continued services of our executive officers and other key engineering, sales, marketing, manufacturing and

support personnel, as well as our ability to effectively transition to their successors. We can provide no assurance that we will be able to find suitable
successors to key roles as transitions occur or that any identified successor will be successfully integrated into our management team. Our inability to do so,
or to retain other key employees or effectively transition to their successors, or any delay in filling any such positions, could harm our business and our
results of operations.

The long sales cycles for many of our products may cause us to incur significant expenses without offsetting net sales.

Customers often view the purchase of our products as a significant and strategic decision. As a result, customers typically expend significant effort in
evaluating, testing and qualifying our products before making a decision to purchase them, resulting in a lengthy initial sales cycle. While our customers are
evaluating our products and before they place an order with us, we may incur substantial sales and marketing and research and development expenses to
customize our products to the customers' needs. We may also expend significant management efforts, increase manufacturing capacity and order long lead-
time components or materials prior to receiving an order. Even after this evaluation process, a potential customer may not purchase our products. As a result,
these long sales cycles may cause us to incur significant expenses without ever receiving net sales to offset such expenses.

The markets in which we sell our products are intensely competitive and increased competition could cause reduced sales levels, reduced gross margins
or the loss of market share.

Competition in the various photonics markets in which we provide products is very intense. We compete against a number of large public and private
companies, including IPG Photonics Corporation, Lumentum, MKS, Novanta Inc., nLIGHT, Inc., II-VI, Wuhan Raycus Fiber Laser Technologies Co., Ltd,
and Trumpf GmbH, as well as other smaller companies. Some of our competitors are large companies that have significant financial, technical, marketing
and other resources. These competitors may be able to devote greater resources than we can to the development, promotion, sale and support of their
products. Some of our competitors are much better positioned than we are to acquire other companies in order to gain new technologies or products that may
displace our product lines. Any of these acquisitions could give our competitors a strategic advantage. Any business combinations or mergers among our
competitors, forming larger companies with greater resources, could result in increased competition, price reductions, reduced margins or loss of market
share, any of which could materially and adversely affect our business, results of operations and financial condition.

Additional competitors may enter the markets in which we serve, both foreign and domestic, and we are likely to compete with new companies in the

future. For example, in recent years there have been a growing number of companies in China that, in some cases aided by government subsidies, are
targeting our markets and are exerting significant price pressure in certain of our product markets, in particular the HPFL products used in the metal cutting
market in China, which led to our decision to exit this market. These companies will likely in the future be able to expand into broader product markets,
which may result in additional competitive pressures on us. We may also encounter potential customers that, due to existing relationships with our
competitors, are committed to the products offered by these competitors. Further, our current or potential customers may determine to develop and produce
products for their own use which are competitive to our products. Such vertical integration could reduce the market opportunity for our products. As a result
of the foregoing factors, we expect that competitive pressures may result in price reductions, reduced margins, loss of sales and loss of market share. In
addition, in markets where there are a limited number of customers, competition is particularly intense.

If we fail to accurately forecast component and material requirements for our products, we could incur additional costs and incur significant delays in
shipments, which could result in a loss of customers.

We use rolling forecasts based on anticipated product orders and material requirements planning systems to determine our product requirements. It is
very important that we accurately predict both the demand for our products and the lead times required to obtain the necessary components and materials.
We depend on our suppliers for most of our product components and materials. Lead times for components and materials that we order vary significantly
and depend on factors including the specific supplier requirements, the size of the order, contract terms and current market demand for components. For
substantial increases in our sales levels of certain products, some of our suppliers may need at least nine months lead-time. If we overestimate our
component and material requirements, we may have excess inventory, which would increase our costs. If we underestimate our component and material
requirements, we may have inadequate inventory, which could interrupt and delay delivery of our products to our customers. We expect that the volatility
and uncertainty created by the COVID-19 pandemic in the markets we serve will exacerbate these issues, and any of these occurrences would negatively
impact our net sales, business or operating results.

34

Our reliance on contract manufacturing and outsourcing may adversely impact our financial results and operations due to our decreased control over
the performance and timing of certain aspects of our manufacturing.

Our manufacturing strategy includes partnering with contract manufacturers to outsource non-core sub-assemblies and less complex turnkey products,

including some performed at international sites located in Asia and Eastern Europe. Our ability to resume internal manufacturing operations for certain
products and components in a timely manner may be eliminated. The cost, quality, performance and availability of contract manufacturing operations are
and will be essential to the successful production and sale of many of our products. Our financial condition or results of operation could be adversely
impacted if any contract manufacturer or other supplier is unable for any reason, including as a result of the COVID-19 pandemic and the negative effect it
is having on the global economy, to meet our cost, quality, performance, and availability standards. We may not be able to provide contract manufacturers
with product volumes that are high enough to achieve sufficient cost savings. If shipments fall below forecasted levels we may incur increased costs or be
required to take ownership of the inventory. Also, our ability to control the quality of products produced by contract manufacturers may be limited and
quality issues may not be resolved in a timely manner, which could adversely impact our financial condition or results of operations.

If we fail to effectively manage our growth or, alternatively, our spending during downturns, our business could be disrupted, which could harm our
operating results.

Growth in sales, combined with the challenges of managing geographically dispersed operations, can place a significant strain on our management

systems and resources, and our anticipated growth in future operations could continue to place such a strain. The failure to effectively manage our growth
could disrupt our business and harm our operating results. Our ability to successfully offer our products and implement our business plan in evolving
markets requires an effective planning and management process. In economic downturns, we must effectively manage our spending and operations to ensure
our competitive position during the downturn, as well as our future opportunities when the economy improves, remain intact. The failure to effectively
manage our spending and operations could disrupt our business and harm our operating results.

Our market is unpredictable and characterized by rapid technological changes and evolving standards demanding a significant investment in research
and development, and, if we fail to address changing market conditions, our business and operating results will be harmed.

The photonics industry is characterized by extensive research and development, rapid technological change, frequent new product introductions,
changes in customer requirements and evolving industry standards. Because this industry is subject to rapid change, it is difficult to predict its potential size
or future growth rate. Our success in generating net sales in this industry will depend on, among other things:

• maintaining and enhancing our relationships with our customers;

•

•

the education of potential end-user customers about the benefits of lasers and laser systems; and

our ability to accurately predict and develop our products to meet industry standards.

We cannot assure you that our expenditures for research and development will result in the introduction of new products or, if such products are
introduced, that those products will achieve sufficient market acceptance or to generate sales to offset the costs of development. Our failure to address rapid
technological changes in our markets could adversely affect our business and results of operations.

Our future success depends on our ability to develop and successfully introduce new and enhanced products that meet the needs of our customers.

Our current products address a broad range of commercial and scientific research applications in the photonics markets. We cannot assure you that the

market for these applications will continue to generate significant or consistent demand for our products. Demand for our products could be significantly
diminished by disrupting technologies or products that replace them or render them obsolete. Furthermore, the new and enhanced products in certain
markets generally continue to be smaller in size and have lower ASPs, and therefore, we have to sell more units to maintain revenue levels. Accordingly, we
must continue to invest in research and development in order to develop competitive products.

Our future success depends on our ability to anticipate our customers' needs and develop products that address those needs. Introduction of new

products and product enhancements will require that we effectively transfer production processes from research and development to manufacturing and
coordinate our efforts with those of our suppliers to achieve volume production rapidly. If we fail to transfer production processes effectively, develop
product enhancements or introduce new products in sufficient quantities to meet the needs of our customers as scheduled, our net sales may be reduced and
our business may be harmed.

35

Our and our customers' operations would be seriously harmed if our logistics or facilities or those of our suppliers, our customers' suppliers or our
contract manufacturers were to experience catastrophic loss.

Our operations, logistics and facilities and those of our customers, suppliers and contract manufacturers could be subject to a catastrophic loss from

fire, flood, earthquake, volcanic eruption, work stoppages, power outages (particularly the rolling blackouts recently experienced in China), acts of war,
pandemics such as COVID-19, energy shortages, theft of assets, other natural disasters or terrorist activity. A substantial portion of our research and
development activities, manufacturing, our corporate headquarters and other critical business operations are located near major earthquake faults in Santa
Clara, California, an area with a history of seismic events. Any such loss or detrimental impact to any of our operations, logistics or facilities could disrupt
our operations, delay production, shipments and net sales and result in large expenses to repair or replace the facility. While we have obtained insurance to
cover most potential losses, after reviewing the costs and limitations associated with earthquake insurance, we have decided not to procure such insurance.
We believe that this decision is consistent with decisions reached by numerous other companies located nearby. We cannot assure you that our existing
insurance coverage will be adequate against all other possible losses.

ACQUISITION RISKS

We may not be able to integrate the business of completed or future acquisitions successfully with our own, realize the anticipated benefits of such
acquisitions or manage our expanded operations, any of which would adversely affect our results of operations.

Acquisition integration efforts are costly due to the large number of processes, policies, procedures, locations, operations, technologies and systems to

be integrated, including purchasing, accounting and finance, sales, service, operations, payroll, pricing, marketing and employee benefits. Integration
expenses could, particularly in the short term, exceed the savings we expect to achieve from the elimination of duplicative expenses and the realization of
economies of scale, which could result in significant charges to earnings that we cannot currently quantify. Potential difficulties that we may encounter as
part of the integration process include the following:

•

•

•

•

•

the inability to successfully combine our business with the acquired company in a manner that permits the combined company to achieve the full
synergies and other benefits anticipated to result from the merger;

complexities associated with managing the combined businesses, including difficulty addressing possible differences in corporate cultures and
management philosophies and the challenge of integrating products, services, complex and different information technology systems (including
different Enterprise Management Systems), control and compliance processes, technology, networks and other assets of each of the companies in a
cohesive manner;

diversion of the attention of our management;

the disruption of, or the loss of momentum in, our business; and

inconsistencies in standards, controls, procedures or policies.

Any of the foregoing could adversely affect our ability to maintain relationships with customers, suppliers, employees and other constituencies or our

ability to achieve the anticipated benefits of the merger, or could reduce our earnings or otherwise adversely affect our business and financial results. If
difficulties arise in the future and we are unable to resolve them in a timely manner, we may experience a shortage of parts and inventory or otherwise be
unable to meet demand, which could have a material adverse impact on our results of operations.

Following an acquisition, the size and complexity of the business of the combined company could increase significantly. Our future success depends,

in part, upon our ability to manage this expanded business, which could pose substantial challenges for management, including challenges related to the
management and monitoring of new operations and associated increased costs and complexity. The execution of these consolidation projects could result in
temporary loss of productivity or operational efficiency, interruptions in manufacturing or other unforeseen challenges while the projects are ongoing.
Moreover, there can be no assurances that we will be successful in realizing the anticipated savings in connection with these consolidations or with our
broader efforts to manage our expanded business or that we will realize the expected synergies and benefits anticipated from the merger.

Historically, acquisitions have been an important element of our strategy. However, we may not find suitable acquisition candidates in the future and we
may not be able to successfully integrate and manage acquired businesses. Any acquisitions we make could disrupt our business and harm our financial
condition.

We have in the past made both large and smaller strategic acquisitions of other corporations and entities, including Electro-Optics Technology in April

2021 and Rofin in November 2016, as well as asset purchases, and we continue to evaluate

36

potential strategic acquisitions of complementary companies, products and technologies. In the event of any future acquisitions, we could:

•

•

•

•

•

issue stock that would dilute our current stockholders' percentage ownership;

pay cash that would decrease our working capital;

incur debt;

assume liabilities; or

incur expenses related to impairment of goodwill and other long-lived assets, as we incurred in the quarter ended April 4, 2020 totaling $451.0
million.

Acquisitions also involve numerous risks, including:

•

•

•

•

•

•

•

•

•

•

problems combining the acquired operations, systems, technologies or products;

an inability to realize expected operating efficiencies or product integration benefits;

difficulties in coordinating and integrating geographically separated personnel, organizations, systems and facilities;

difficulties integrating business cultures;

unanticipated costs or liabilities, including the costs associated with improving the internal controls of the acquired company;

diversion of management's attention from our core businesses;

adverse effects on existing business relationships with suppliers and customers;

potential loss of key employees, particularly those of the purchased organizations;

incurring unforeseen obligations or liabilities in connection with acquisitions; and

the failure to complete acquisitions even after signing definitive agreements which, among other things, would result in the expensing of potentially
significant professional fees and other charges in the period in which the acquisition or negotiations are terminated.

We cannot assure you that we will be able to successfully identify appropriate acquisition candidates, to integrate any businesses, products,
technologies or personnel that we might acquire in the future or achieve the anticipated benefits of such transactions, which may harm our business.

FINANCIAL RISKS

Our indebtedness following the Rofin merger is substantially greater than our indebtedness prior to the merger. This increased level of indebtedness
could adversely affect us, including by decreasing our business flexibility, and will increase our borrowing costs.

In November 2016, we entered into a credit agreement (the "Credit Agreement"), which provided for a 670.0 million Euro term loan (the "Euro Term

Loan"), all of which was drawn, and a $100.0 million revolving credit facility (the "Revolving Credit Facility"), under which a 10 million Euro letter of
credit was issued. As of October 2, 2021, 351.5 million Euros were outstanding under the Euro Term Loan. As of October 2, 2021, the Revolving Credit
Facility had been used for guarantees of 10.0 million Euros as well as borrowings of $10.0 million. We repaid outstanding borrowings on October 29, 2021
and on November 5, 2021, the Revolving Credit Facility terminated. In connection with the termination of our Revolving Credit Facility, on October 29,
2021, we entered into a 10.0 million Euro letter of credit facility, rolled our existing letter of credit into that facility and deposited 10.5 million Euros with
Barclays as cash collateral to secure the payment obligations under such facility. We may incur additional indebtedness in the future by entering into new
financing arrangements. Our ability to pay interest and repay the principal of our current indebtedness is dependent upon our ability to manage our business
operations and the ongoing interest rate environment. There can be no assurance that we will be able to manage any of these risks successfully.

The Credit Agreement contains customary affirmative covenants, including covenants regarding the payment of taxes and other obligations,
maintenance of insurance, reporting requirements and compliance with applicable laws and regulations, and negative covenants, including covenants
limiting the ability of us and our subsidiaries to, among other things, incur debt, grant liens, make investments, make certain restricted payments, transact
with affiliates, and sell assets. The Credit Agreement also requires us and our subsidiaries to maintain a senior secured net leverage ratio as of the last day of
each fiscal quarter of less of

37

than or equal to 3.50 to 1.00. The Credit Agreement contains customary events of default that include, among other things, payment defaults, cross defaults
with certain other indebtedness, violation of covenants, inaccuracy of representations and warranties in any material respect, change in control of us and
Coherent Holding BV & Co. K.G. (formerly Coherent Holding GmbH), judgment defaults, and bankruptcy and insolvency events. If an event of default
exists, the lenders may require the immediate payment of all obligations and exercise certain other rights and remedies provided for under the Credit
Agreement, the other loan documents and applicable law. The acceleration of such obligations is automatic upon the occurrence of a bankruptcy and
insolvency event of default. There can be no assurance that we will have sufficient financial resources or we will be able to arrange financing to repay our
borrowings at such time.

Certain of our financial arrangements, including our Credit Agreement, are made at variable rates that use interbank offered rates, or IBORs, including

the Euro Interbank Offered Rate, or EURIBOR and the London Interbank Offered Rate, or LIBOR (or metrics derived from or related to LIBOR), as a
benchmark for establishing the interest rate. IBORs are or have been reformed, may cease to be available or may be declared to be no longer representative
of the underlying market and economic realities. In such a case IBORs and specifically LIBOR may need to be replaced with a replacement rate. While
EURIBOR is the subject of reform, in March 2021, the United Kingdom’s Financial Conduct Authority, which regulates LIBOR, announced that it intends
to cease or otherwise declare as no longer representative certain LIBOR settings on December 31, 2021 and the remainder of the U.S. dollar LIBOR settings
on June 30, 2023. At this time, we cannot predict how markets will respond to reform or the proposed alternative rates or the effect of any changes to IBORs
or the discontinuation or non-representativeness of LIBOR. New methods of calculating IBORs that may be established or the establishment of alternative
reference rates could have an adverse impact on the market value for or value of IBOR-linked securities, loans and other financial obligations or extensions
of credit held by or due to us. Changes in market interest rates may influence our financing costs, returns on financial investments and the valuation of
derivative contracts and could reduce our earnings and cash flows. There is no guarantee that a transition from IBORs and specifically LIBOR to an
alternative will not result in financial market disruptions, significant increases in benchmark rates, or borrowing costs to borrowers, any of which could have
an adverse effect on our business, financial condition, and results of operations.

Our substantially increased indebtedness and higher debt-to-equity ratio as a result of the Rofin merger in comparison to that prior to the merger will
have the effect, among other things, of reducing our flexibility to respond to changing business and economic conditions and will increase our borrowing
costs. In addition, the amount of cash required to service our increased indebtedness levels and thus the demands on our cash resources will be greater than
the amount of cash flows required to service our indebtedness or that of Rofin individually prior to the merger. The increased levels of indebtedness could
also reduce funds available for our investments in product development as well as capital expenditures, dividends, share repurchases and other activities and
may create competitive disadvantages for us relative to other companies with lower debt levels.

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

Under accounting principles generally accepted in the United States, we review our intangible assets for impairment when events or changes in
circumstances indicate the carrying value may not be recoverable. Goodwill is required to be tested for impairment at least annually. Factors that may be
considered in determining whether a change in circumstances indicating that the carrying value of our goodwill or other intangible assets may not be
recoverable include declines in our stock price and market capitalization or future cash flows projections. A decline in our stock price, or any other adverse
change in market conditions, particularly if such change has the effect of changing one of the critical assumptions or estimates we used to calculate the
estimated fair value of our reporting units, could result in a change to the estimation of fair value that could result in an impairment charge. Any such
material charges, whether related to goodwill or purchased intangible assets, may have a material negative impact on our financial and operating results. For
example, in the quarter ended April 4, 2020, the worldwide spread of COVID-19 created significant volatility, uncertainty and disruption to the global
economy, representing an indicator to test our goodwill for impairment. As a result of that test, we recorded a non-cash pre-tax charge, in the quarter ended
April 4, 2020, related to the ILS reporting unit of $327.2 million, reducing the goodwill balance of the reporting unit to zero. In addition, we performed
impairment tests on the long-lived assets allocated to the asset group of the ILS reporting unit, including intangible assets, property, plant and equipment and
ROU assets as of April 4, 2020 and recorded non-cash pre-tax charges, in the quarter ended April 4, 2020, related to the impairment intangible assets,
property, plant and equipment and ROU assets of the ILS reporting unit of $33.9 million, $85.6 million and $1.8 million, respectively.

Our cash and cash equivalents and short-term investments are managed through various banks around the world and volatility in the capital and credit
market conditions could cause financial institutions to fail or materially harm service levels provided by such banks, both of which could have an
adverse impact on our ability to timely access funds.

World capital and credit markets have been and may continue to experience volatility and disruption. In some cases, the markets have exerted
downward pressure on stock prices and credit capacity for certain issuers, as well as pressured the solvency of some financial institutions. These financial
institutions, including banks, have had difficulty timely performing regular services and in some cases have failed or otherwise been largely taken over by
governments. We maintain our cash,

38

cash equivalents and short-term investments with a number of financial institutions around the world. Should some or all of these financial institutions fail or
otherwise be unable to timely perform requested services, we would likely have limited ability to timely access our cash deposited with such institutions, or,
in extreme circumstances the failure of such institutions could cause us to be unable to access cash for the foreseeable future. If we are unable to quickly
access our funds when we need them, we may need to increase the use of our existing credit lines or access more expensive credit, if available. If we are
unable to access our cash or if we access existing or additional credit or are unable to access additional credit, it could have a negative impact on our
operations, including our reported net income. In addition, the willingness of financial institutions to continue to accept our cash deposits will impact our
ability to diversify our investment risk among institutions.

We are exposed to credit risk and fluctuations in the market values of our investment portfolio.

Although we have not recognized any material losses on our cash, cash equivalents and short-term investments, future declines in their market values

could have a material adverse effect on our financial condition and operating results. Given the global nature of our business, we have investments both
domestically and internationally. There has recently been growing pressure on the creditworthiness of sovereign nations, particularly in Europe where a
significant portion of our cash, cash equivalents and short-term investments are invested, which results in corresponding pressure on the valuation of the
securities issued by such nations. Additionally, our overall investment portfolio is often concentrated in government-issued securities such as U.S. Treasury
securities and government agencies, corporate notes, commercial paper and money market funds. Credit ratings and pricing of these investments can be
negatively impacted by liquidity, credit deterioration or losses, financial results, or other factors. Additionally, liquidity issues or political actions by
sovereign nations could result in decreased values for our investments in certain government securities. As a result, the value or liquidity of our cash, cash
equivalents and short-term investments could decline or become materially impaired, which could have a material adverse effect on our financial condition
and operating results. See "Item 7A. Quantitative and Qualitative Disclosures about Market Risk."

INTELLECTUAL PROPERTY AND CYBERSECURITY RISKS

If we are unable to protect our proprietary technology, our competitive advantage could be harmed.

Maintenance of intellectual property rights and the protection thereof is important to our business. We rely on a combination of patent, copyright,

trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. Our patent applications may not be approved, any
patents that may be issued may not sufficiently protect our intellectual property and any issued patents may be challenged by third parties. Other parties may
independently develop similar or competing technology or design around any patents that may be issued to us. We cannot be certain that the steps we have
taken will prevent the misappropriation of our intellectual property, particularly in foreign countries where the laws may not protect our proprietary rights as
fully as in the United States. Further, we may be required to enforce our intellectual property or other proprietary rights through litigation, which, regardless
of success, could result in substantial costs and diversion of management's attention. Additionally, there may be existing patents of which we are unaware
that could be pertinent to our business and it is not possible for us to know whether there are patent applications pending that our products might infringe
upon since these applications are often not publicly available until a patent is issued or published.

We have been and may, in the future, be subject to claims or litigation from third parties, for claims of infringement of their proprietary rights or to
determine the scope and validity of our proprietary rights or the proprietary rights of competitors or other rights holders. These claims could result in
costly litigation and the diversion of our technical and management personnel. Adverse resolution of litigation may harm our operating results or
financial condition.

In recent years, there has been significant litigation in the United States and around the world involving patents and other intellectual property rights.

This has been seen in our industry, for example in the concluded patent-related litigation between IMRA America, Inc. ("Imra") and IPG Photonics
Corporation and in Imra's concluded patent-related litigation against two of our German subsidiaries. From time to time, like many other technology
companies, we have received communications from other parties asserting the existence of patent rights, copyrights, trademark rights or other intellectual
property rights which such third parties believe may cover certain of our products, processes, technologies or information. In the future, we may be a party
to litigation to protect our intellectual property or as a result of an alleged infringement of others' intellectual property whether through direct claims or by
way of indemnification claims of our customers, as, in some cases, we contractually agree to indemnify our customers against third-party infringement
claims relating to our products. These claims and any resulting lawsuit, if successful, could subject us to significant liability for damages or invalidation of
our proprietary rights. These lawsuits, regardless of their success, would likely be time-consuming and expensive to resolve and would divert management
time and attention. In addition to paying possibly significant monetary damages, any potential intellectual property litigation could also force us to do one or
more of the following:

•

stop manufacturing, selling or using our products that use the infringed intellectual property;

39

•

•

obtain from the owner of the infringed intellectual property right a license to sell or use the relevant technology, although such license may not be
available on reasonable terms, or at all; or

redesign the products that use the technology.

If we are forced to take any of these actions or are otherwise a party to lawsuits of this nature, we may incur significant losses and our business may be

seriously harmed. We do not have insurance to cover potential claims of this type.

Our information systems are subject to attacks, interruptions and failures.

As part of our day-to-day business, we store our data and certain data about our customers in our global information technology system. While our
system is designed with access security, if a third party gains unauthorized access to our data, including any regarding our customers, such a security breach
could expose us to a risk of loss of this information, loss of business, litigation and possible liability. Our security measures may be breached as a result of
third-party action, including intentional misconduct by computer hackers, employee error, malfeasance or otherwise. Additionally, third parties may attempt
to fraudulently induce employees or customers into disclosing sensitive information such as user names, passwords or other information in order to gain
access to our customers' data or our data, including our intellectual property and other confidential business information, or our information technology
systems. Because the techniques used to obtain unauthorized access, or to sabotage systems, change frequently and generally are not recognized until
launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. Any unauthorized access could
result in a loss of confidence by our customers, damage our reputation, disrupt our business, lead to legal liability and negatively impact our future sales.
Additionally, such actions could result in significant costs associated with loss of our intellectual property, impairment of our ability to conduct our
operations, rebuilding our network and systems, prosecuting and defending litigation, responding to regulatory inquiries or actions, paying damages or
taking other remedial steps.

Difficulties with our enterprise resource planning system and other parts of our global information technology system could harm our business and
results of operation. If our network security measures are breached and unauthorized access is obtained to a customer's data or our data or our
information technology systems, we may incur significant legal and financial exposure and liabilities.

Like many modern multinational corporations, we maintain a global information technology system, including software products licensed from third
parties. Any system, network or Internet failures, misuse by system users, the hacking into or disruption caused by the unauthorized access by third parties
or loss of license rights could disrupt our ability to timely and accurately manufacture and ship products or to report our financial information in compliance
with the timelines mandated by the SEC. Any such failure, misuse, hacking, disruptions or loss would likely cause a diversion of management's attention
from the underlying business and could harm our operations. In addition, a significant failure of our global information technology system could adversely
affect our ability to complete an evaluation of our internal controls and attestation activities pursuant to Section 404 of the Sarbanes-Oxley Act of 2002.

LEGAL, TAX, REGULATORY AND COMPLIANCE RISKS

Changes in tax rates, tax liabilities or tax accounting rules could affect future results.

As a global company, we are subject to taxation in the United States and various other countries and jurisdictions. Significant judgment is required to

determine our worldwide tax liabilities. A number of factors may affect our future effective tax rates including, but not limited to:

•

•

•

•

•

•

interpretation and impact of the recently enacted and aforementioned U.S. tax laws, the Tax Act and the CARES Act;

the establishment or release of valuation allowances against deferred tax assets may cause greater volatility in the effective tax rate;

changes in our current and future global structure based on the Rofin acquisition and restructuring that involved significant movement of U.S. and
foreign entities and our ability to maintain favorable tax treatment as a result of various Rofin restructuring efforts and business activities;

the outcome of discussions with various tax authorities regarding intercompany transfer pricing arrangements;

changes that involve other acquisitions, restructuring or an increased investment in technology outside of the United States to better align asset
ownership and business functions with revenues and profits;

changes in the composition of earnings in countries or states with differing tax rates;

40

•

•

•

•

•

•

•

•

•

the resolution of transfer pricing issues through the Competent Authority process between South Korea, Germany and the United States arising
from the German tax audits for fiscal 2011-2016 and South Korean tax audits for fiscal 2014-2017;

adjustments to estimated taxes upon finalization of various tax returns;

increases in expenses not deductible for tax purposes, including impairments of goodwill in connection with acquisitions;

our ability to meet the eligibility requirements for tax holidays of limited time tax-advantage status and any challenges by tax authorities regarding
the timing of benefits derived from those holidays;

changes in available tax credits;

changes in share-based compensation;

changes in other tax laws or the interpretation of such tax laws, including the Base Erosion Profit Shifting action plan and two-pillar solution
addressing the digitalization of the global economy implemented by the Organization for Economic Co-operation and Development ("OECD") as
well as an OECD-led global minimum corporate tax rate, and President Biden's various proposals to increase the U.S. corporate income tax rates
and increase U.S. taxation on foreign earnings;

changes in generally accepted accounting principles; and

significant fluctuations in business activities due to the COVID-19 pandemic.

As indicated above, we are engaged in discussions with various tax authorities regarding the appropriate level of profitability for Coherent entities and

this may result in changes to our worldwide tax liabilities. In addition, we are subject to regular examination of our income tax returns by the 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 provisions and accruals, which could materially and
adversely affect our operating results and financial condition.

From time to time the United States, foreign and state governments make substantive changes to tax rules and the application of rules to companies.

For example, the Tax Act has a significant impact on the taxation of Coherent including the U.S. tax treatment of our foreign operations. The Tax Act is
subject to further interpretation by the U.S. federal and state governments and regulatory organizations, legislative updates or new regulations, or changes in
accounting standards for income taxes. These actions may have a material impact on our financial results.

Governmental regulations, including tariffs and duties, affecting the import or export of products could negatively affect our business, financial

condition and results of operations.

The United States, Germany, the European Union, the United Kingdom, China, South Korea, Japan and many other foreign governments impose tariffs

and duties on the import and export of products, including some of those which we sell. In particular, given our worldwide operations, we pay duties on
certain products when they are imported into the United States for repair work as well as on certain of our products which are manufactured by our foreign
subsidiaries. These products can be subject to a duty on the product value.

Additionally, the United States and various foreign governments have imposed tariffs, controls, export license requirements and restrictions on the
import or export of some technologies, especially those related to the power and performance of our products and encryption technology. From time to time,
government agencies have proposed additional regulation of encryption technology, such as requiring the escrow and governmental recovery of private
encryption keys. Governmental regulation of encryption technology and regulation of imports or exports, or our failure to obtain required import or export
licenses or other approvals for our products, could harm our international and domestic sales and adversely affect our net sales.

Exports of certain of our products are subject to export controls imposed by the U.S. government and administered by the U.S. Departments of State
and Commerce. In certain instances, these regulations may require pre-shipment authorization from the administering department. For products subject to
the EAR, 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 ITAR require a license. Certain of our products are subject to EAR and to ITAR.
Products and the associated technical data developed and manufactured in our foreign locations are subject to export controls of the applicable

41

foreign nation. Given the current global political climate, obtaining export licenses can be difficult and time-consuming and may result in substantial
expenses and diversion of management’s attention. Failure (i) to obtain the required export licenses could reduce our revenue and/or (ii) to adequately
address these directives could result in substantial payments, fines, penalties or damages - including the suspension or loss of our export privileges, any of
which could have a material adverse effect on our business or financial position, results of operations, or cash flows. For example, German authorities are
currently investigating an export compliance matter involving one of our German subsidiaries involving four former employees (whose employment was
terminated following our discovery of this matter) and while we do not believe that the final resolution of this matter will be material to our consolidated
financial position, results of operations or cash flows, the German government investigation is ongoing and it is possible that substantial payments, fines,
penalties or damages could result.

The United States has recently instituted or proposed changes in trade policies that include the negotiation or termination of trade agreements, the
imposition of higher tariffs on imports into the United States including, in particular, on Chinese goods, economic sanctions on individuals, corporations or
countries and other government regulations affecting trade between the United States and other countries where we conduct our business. In addition, the
Japanese government has recently instituted trade restrictions affecting the export to South Korea of certain products and materials used in the manufacture
of flat panel displays and in the semiconductor industry. These policy changes and proposals could require time-consuming and expensive alterations to our
business operations and may result in greater restrictions and economic disincentives on international trade, which could negatively impact our
competitiveness in jurisdictions around the world as well as lead to an increase in costs in our supply chain. Given that we are a multinational corporation,
with manufacturing located both in the United States and internationally, we may face additional susceptibility to negative impacts from these tariffs or
change in trade policies regarding our inter-company trade practices. For example, we have recently seen a reduction in demand from our Chinese customers
particularly in the materials processing space. Some of these customers are reevaluating expansion plans and delaying and, in limited cases, cancelling
orders. In addition, new tariffs and other changes in U.S. trade policy could trigger retaliatory actions by affected countries, and certain foreign governments,
including the Chinese government (which has imposed retaliatory tariffs on a range of U.S. goods including certain photonics products), some of which have
instituted or are considering imposing trade sanctions on certain U.S. manufactured goods. Such changes by the United States and other countries have the
potential to adversely impact U.S. and worldwide economic conditions, our industry and the global demand for our products, and as a result, could
negatively affect our business, financial condition and results of operations.

As a multinational corporation, we may be subject to audits by tax, export and customs authorities, as well as other government agencies. Any future

audits could lead to assessments that could have a material adverse effect on our business or financial position, results of operations, or cash flows.

We use standard laboratory and manufacturing materials that could be considered hazardous and we could be liable for any damage or liability
resulting from accidental environmental contamination or injury.

Although most of our products do not incorporate hazardous or toxic materials and chemicals, some of the gases used in our excimer lasers and some

of the liquid dyes used in some of our scientific laser products are highly toxic. In addition, our operations involve the use of standard laboratory and
manufacturing materials that could be considered hazardous. Also, if a facility fire were to occur at our Sunnyvale, California site and were to spread to a
reactor used to grow semiconductor wafers, it could release highly toxic emissions. We believe that our safety procedures for handling and disposing of such
materials comply with all federal, state and offshore regulations and standards. However, the risk of accidental environmental contamination or injury from
such materials cannot be entirely eliminated. In the event of such an accident involving such materials, we could be liable for damages and such liability
could exceed the amount of our liability insurance coverage and the resources of our business which could have an adverse effect on our financial results or
our business as a whole.

Compliance or the failure to comply with current and future environmental regulations could cause us significant expense.

We are subject to a variety of federal, state, local and foreign environmental regulations relating to the use, storage, discharge and disposal of

hazardous chemicals used during our manufacturing process or requiring design changes or recycling of products we manufacture. If we fail to comply with
any present and future regulations, we could be subject to future liabilities, the suspension of production or a prohibition on the sale of products we
manufacture. In addition, such regulations could restrict our ability to expand our facilities or could require us to acquire costly equipment, or to incur other
significant expenses to comply with environmental regulations, including expenses associated with the recall of any non-compliant product and the
management of historical waste.

From time to time new regulations are enacted, and it is difficult to anticipate how such regulations will be implemented and enforced. We continue to

evaluate the necessary steps for compliance with regulations as they are enacted. These regulations include, for example, the Registration, Evaluation,
Authorization and Restriction of Chemical substances, the Restriction on the Use of Certain Hazardous Substances in Electrical and Electronic Equipment
Directive and the Waste Electrical and Electronic Equipment Directive enacted in the European Union, which regulate the use of certain hazardous

42

substances in, and require the collection, reuse and recycling of waste from, certain products we manufacture. This and similar legislation that has been or is
in the process of being enacted in Japan, China, South Korea and various states of the United States may require us to re-design our products to ensure
compliance with the applicable standards, for example by requiring the use of different types of materials. These redesigns or alternative materials may
detrimentally impact the performance of our products, add greater testing lead-times for product introductions or have other similar effects. We believe we
comply with all such legislation where our products are sold, and we will continue to monitor these laws and the regulations being adopted under them to
determine our responsibilities. In addition, we are monitoring legislation relating to the reduction of carbon emissions from industrial operations to
determine whether we may be required to incur any additional material costs or expenses associated with our operations. We are not currently aware of any
such material costs or expenses. The SEC has promulgated rules requiring disclosure regarding the use of certain "conflict minerals" mined from the
Democratic Republic of Congo and adjoining countries and procedures regarding a manufacturer's efforts to prevent the sourcing of such minerals. The
implementation of such rules has required us to incur additional expense and internal resources and may continue to do so in the future, particularly in the
event that only a limited pool of suppliers are available to certify that products are free from "conflict minerals." Our failure to comply with any of the
foregoing regulatory requirements or contractual obligations could result in our being directly or indirectly liable for costs, fines or penalties and third-party
claims, and could jeopardize our ability to conduct business in the United States and foreign countries.

Failure to maintain effective internal controls may cause a loss of investor confidence in the reliability of our financial statements or cause us to delay
filing our periodic reports with the SEC and adversely affect our stock price.

The SEC, as directed by Section 404 of the Sarbanes-Oxley Act of 2002, adopted rules requiring public companies to include a report of management

on internal control over financial reporting in their annual reports on Form 10-K that contain an assessment by management of the effectiveness of our
internal control over financial reporting. In addition, our independent registered public accounting firm must attest to and report on the effectiveness of our
internal control over financial reporting. Although we test our internal control over financial reporting in order to ensure compliance with the Section 404
requirements, our failure to maintain adequate internal controls over financial reporting could result in an adverse reaction in the financial marketplace due
to a loss of investor confidence in the reliability of our financial statements or a delay in our ability to timely file our periodic reports with the SEC, which
ultimately could negatively impact our stock price.

We may face particular privacy, data security and data protection risks due to laws and regulations regulating the protection or security of personal and
other sensitive data.

We may face particular privacy, data security and data protection risks due to laws and regulations regulating the protection or security of personal and
other sensitive data, including in particular several laws and regulations that have recently been enacted or adopted or are likely to be enacted or adopted in
the future. For instance, effective May 25, 2018, the European General Data Protection Regulation ("GDPR") imposed additional obligations and risk upon
our business and increased substantially the penalties to which we could be subject in the event of any non-compliance. GDPR requires companies to satisfy
requirements regarding the handling of personal data (generally, of EU residents), including its use, protection and the rights of affected persons regarding
their data. Failure to comply with GDPR requirements could result in fines of up to 20 million Euro or 4% of global annual revenues, whichever is higher.
We have taken extensive measures to ensure compliance with GDPR and to minimize the risk of incurring any penalties and we continue to adapt to the
developing interpretation and enforcement of GDPR as well as emerging best practice standards. For example, we have introduced an international Data
Protection Organization, a European Data Protection Policy, a system for Data Protection Management and Documentation and implemented an
international Intra Group Data Transfer Agreement including the EU Standard Contractual Clauses. In addition, several other jurisdictions around the world
have recently enacted privacy laws or regulations similar to GDPR. For instance, California enacted the California Consumer Privacy Act ("CCPA"), which
became effective January 1, 2020 and which gives consumers many of the same rights as those available under GDPR. Several laws similar to the CCPA
have been proposed in the United States at both the federal and state level. Like GDPR, other similar laws and regulations, as well as any associated
inquiries or investigations or any other government actions, may be costly to comply with, result in negative publicity, increase our operating costs, require
significant management time and attention, and subject us to remedies that may harm our business.

Violations of anti-bribery, anti-corruption, and/or international trade laws to which we are subject could negatively affect our business, financial
condition and results of operations.

We are subject to laws concerning our business operations and marketing activities in foreign countries where we conduct business. For example, we

are subject to the FCPA, U.S. export control and trade sanction laws, and similar anti-corruption and international trade laws in certain foreign countries,
such as the U.K. Bribery Act. The FCPA generally prohibits U.S. companies and their officers, directors, employees, and intermediaries from making
improper payments to foreign officials for the purpose of obtaining or retaining business abroad or otherwise obtaining favorable treatment. The FCPA also
requires that U.S. public companies maintain books and records that fairly and accurately reflect transactions and maintain an adequate

43

system of internal accounting controls. There can be no assurance that our employees, contractors, sales channel partners and agents will not take actions in
violation of our policies and procedures, which are designed to ensure compliance with such laws. Violations of such laws and/or our policies and
procedures by our employees, contractors, sales channel partners and agents could result in sanctions including civil and criminal fines, disgorgement of
profits and suspension or debarment of our ability to contract with government agencies or receive export licenses and could also result in the termination of
our relationships with customers and suppliers as well as financial reporting problem which could negatively affect our business, financial condition and
results of operations.

RISKS RELATED TO OWNERSHIP OF OUR COMMON STOCK

Provisions of our charter documents and Delaware law, and our Change of Control and Leadership Change Severance Plan, may have anti-takeover
effects that could prevent or delay a change in control.

Provisions of our certificate of incorporation and bylaws, as well as the terms of our Change of Control and Leadership Change Severance Plan, may

discourage, delay or prevent a merger or acquisition, make a merger or acquisition more costly for a potential acquirer, or make removal of incumbent
directors or officers more difficult. These provisions may discourage takeover attempts and bids for our common stock at a premium over the market price.
These provisions include:

•

•

•

the ability of our board of directors to alter our bylaws without stockholder approval;

limiting the ability of stockholders to call special meetings; and

establishing advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted on by
stockholders at stockholder meetings.

We are subject to Section 203 of the Delaware General Corporation Law, which prohibits a publicly-held Delaware corporation from engaging in a
merger, asset or stock sale or other transaction with an interested stockholder for a period of three years following the date such person became an interested
stockholder, unless prior approval of our board of directors is obtained or as otherwise provided. These provisions of Delaware law also may discourage,
delay or prevent someone from acquiring or merging with us without obtaining the prior approval of our board of directors, which may cause the market
price of our common stock to decline. In addition, we have adopted a change of control severance plan, which provides for the payment of a cash severance
benefit to each eligible employee based on the employee's position. If a change of control occurs, our successor or acquirer will be required to assume and
agree to perform all of our obligations under the change of control severance plan which may discourage potential acquirers or result in a lower stock price.

Our bylaws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between us and our
stockholders, which could limit our stockholders' ability to obtain a different forum for disputes with us or our directors, officers or employees.

Our bylaws provide that the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, another state or
federal court located within the State of Delaware) is the exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action
asserting a claim of breach of a duty (including any fiduciary duty) owed by any current or former director, officer, stockholder, employee or agent to us or
our stockholders, (iii) any action asserting a claim arising out of or relating to any provision of the Delaware General Corporation Law or our certificate of
incorporation or bylaws (each, as in effect from time to time) or as to which the Delaware General Corporation Law confers jurisdiction on the Court of
Chancery of the State of Delaware, or (iv) any action asserting a claim governed by the internal affairs doctrine. Our bylaws also provide that the federal
district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the
Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder. This choice of forum provision may limit a stockholder's ability
to bring a claim in a different judicial forum that such stockholder views as more favorable for such disputes which may discourage such lawsuits against us
and our directors, officers and other employees. Alternatively, if a court were to find the choice of forum provisions contained in our bylaws to be
inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could adversely
affect our business and financial condition.

GENERAL RISK FACTORS

Worldwide economic conditions and related uncertainties could negatively impact demand for our products and results of operations.

Volatility and disruption in the capital and credit markets, depressed consumer confidence, government economic policies, negative economic
conditions, global supply chain issues, volatile corporate profits and reduced capital spending could negatively impact demand for our products. In
particular, it is difficult to develop and implement strategy, sustainable business models and efficient operations, as well as effectively manage supply chain
relationships, in the face of such conditions,

44

including uncertainty regarding the ability of some of our suppliers to continue operations and provide us with uninterrupted supply flow. Our ability to
maintain our research and development investments in our broad product offerings may be adversely impacted in the event that our future sales decline or
remain flat. Spending and the timing thereof by consumers and businesses have a significant impact on our results and, where such spending is delayed or
cancelled, it could have a material negative impact on our operating results. Global economic conditions have become more uncertain and challenging as the
effects of the COVID-19 pandemic continue to have a significant adverse effect on the global economy. Weakness in our end markets has negatively
impacted our bookings, net sales, gross margin and operating expenses, and, if it continues, would have a material adverse effect on our business, financial
condition and results of operations.

Uncertainty in global fiscal policy has likely had an adverse impact on global financial markets and overall economic activity in recent years. Should

this uncertain financial policy continue to occur or recur, it would likely continue to, and may in the future, negatively impact global economic activity. Any
weakness in global economies would also likely have negative repercussions on U.S. and global credit and financial markets, and further exacerbate
sovereign debt concerns in the European Union. All of these factors would likely adversely impact the global demand for our products and the performance
of our investments, and would likely have a material adverse effect on our business, results of operations and financial condition.

Financial turmoil affecting the banking system and financial markets, as has occurred in recent years, could result in tighter credit markets and lower
levels of liquidity in some financial markets. There could be a number of follow-on effects from a tightened credit environment on our business, including
the insolvency of key suppliers or their inability to obtain credit to finance development and/or manufacture products resulting in product delays; inability of
customers to obtain credit to finance purchases of our products and/or customer insolvencies; and failure of financial institutions negatively impacting our
treasury functions. In the event our customers are unable to obtain credit or otherwise pay for our shipped products it could significantly impact our ability to
collect on our outstanding accounts receivable. Other income and expense also could vary materially from expectations depending on gains or losses
realized on the sale or exchange of financial instruments; impairment charges resulting from revaluations of debt and equity securities and other
investments; interest rates; cash balances; and changes in fair value of derivative instruments. Volatility in the financial markets and any overall economic
uncertainty increase the risk that the actual amounts realized in the future on our financial instruments could differ significantly from the fair values
currently assigned to them. Uncertainty about global economic conditions could also continue to increase the volatility of our stock price.

In addition, political and social turmoil related to international conflicts, terrorist acts, civil unrest and mass migration may put further pressure on

economic conditions in the United States and the rest of the world. Unstable economic, political and social conditions make it difficult for our customers,
our suppliers and us to accurately forecast and plan future business activities. If such conditions persist, our business, financial condition and results of
operations could suffer. Additionally, unstable economic conditions can provide significant pressures and burdens on individuals, which could cause them to
engage in inappropriate business conduct. See Item 9A "Controls and Procedures."

We are exposed to lawsuits in the normal course of business which could have a material adverse effect on our business, operating results, or financial
condition.

We are exposed to lawsuits in the normal course of our business, including product liability claims, if personal injury, death or commercial losses occur

from the use of our products. As a public company our stock price fluctuates for a variety of different reasons, some of which may be related to broader
industry and/or market factors. As a result, from time-to-time we may be subject to the risk of litigation due to the fluctuation in stock price or other
governance or market-related factors. While we typically maintain business insurance, including directors' and officers' policies, litigation can be expensive,
lengthy, and disruptive to normal business operations, including the potential impact of indemnification obligations for individuals named in any such
lawsuits. We may not, however, be able to secure insurance coverage on terms acceptable to us in the future. Moreover, the results of complex legal
proceedings are difficult to predict. An unfavorable resolution of a particular lawsuit, including a recall or redesign of products if ultimately determined to
be defective, could have a material adverse effect on our business, operating results, or financial condition.

ITEM 7.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our Consolidated

Financial Statements and related notes included under Item 8 of this annual report. This discussion contains forward-looking statements, which involve risks
and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of certain factors, including
but not limited to those discussed in Item 1A,"Risk Factors" and elsewhere in this annual report. Please see the discussion of forward-looking statements at
the beginning of this annual report under "Special Note Regarding Forward-Looking Statements."

We have applied the FAST Act Modernization and Simplification of Regulation S-K, which limits the discussion to the two most recent fiscal years.

This discussion and analysis deals with comparisons of material changes in the consolidated financial statements for fiscal 2021 and fiscal 2020. For the
comparison of fiscal 2020 and fiscal 2019, see "Management's Discussion and Analysis of Financial Condition and Results of Operations" in Item 7 of our
2020 Annual Report on Form 10-K, filed with the Securities and Exchange Commission on December 1, 2020.

Definitions and analysis of these performance indicators are as follows:

Net Sales

Net sales include sales of lasers, laser systems, laser components, related accessories and services. Net sales for fiscal 2021 increased 20.4% in our
OLS segment and increased 22.1% in our ILS segment from fiscal 2020. For a description of the reasons for changes in net sales refer to the "Results of
Operations" section below.

Gross Profit as a Percentage of Net Sales

Gross profit as a percentage of net sales ("gross profit percentage") is calculated as gross profit for the period divided by net sales for the period. Gross

profit percentage for OLS decreased to 45.4% in fiscal 2021 from 46.0% in fiscal 2020. Gross profit percentage for ILS increased to 28.2% in fiscal 2021
from 14.5% in fiscal 2020. For a description of the reasons for changes in gross profit refer to the "Results of Operations" section below.

48

 
 
 
Research and Development as a Percentage of Net Sales

Research and development as a percentage of net sales ("R&D percentage") is calculated as research and development expense for the period divided
by net sales for the period. Management considers R&D percentage to be an important indicator in managing our business as investing in new technologies
is a key to future growth. R&D percentage decreased to 8.4% in fiscal 2021 from 9.4% in fiscal 2020. For a description of the reasons for changes in R&D
spending refer to the "Results of Operations" section below.

Net Cash Provided by Operating Activities

Net cash provided by operating activities as reflected on our Consolidated Statements of Cash Flows primarily represents the excess of cash collected

from billings to our customers and other receipts over cash paid to our vendors for expenses and inventory purchases to run our business. We believe that
cash flows from operations is an important performance indicator because cash generation over the long term is essential to maintaining a healthy business
and providing funds to help fuel growth. Net cash provided by operating activities in fiscal 2021 was unfavorably impacted by merger and acquisition costs,
including our payment of a termination fee of $217.6 million to Lumentum. For a description of the reasons for changes in Net Cash Provided by Operating
Activities refer to the "Liquidity and Capital Resources" section below.

Free Cash Flow

Free cash flow represents net cash provided by operating activities reduced by purchases of property and equipment, both as reflected on our
Consolidated Statements of Cash Flows. We believe that free cash flow is an important performance indicator because it is a measure of cash generation
after accounting for cash outflows to support operations and maintain capital assets. Cash generation over the long term is essential to maintaining a healthy
business and providing funds to help fuel growth. Free cash flow in fiscal 2021 was unfavorably impacted by merger and acquisition costs, including our
payment of a termination fee of $217.6 million to Lumentum. For a description of the reasons for changes in free cash flow refer to the "Liquidity and
Capital Resources" section below, where we discuss the reasons for changes in net cash provided by operating and investing activities.

Days Sales Outstanding in Receivables

We calculate days sales outstanding ("DSO") in receivables as net receivables at the end of the period divided by net sales during the period and then
multiplied by the number of days in the period, using a 360 day year. DSO in receivables indicates how well we are managing our collection of receivables,
with lower DSO in receivables resulting in higher working capital availability. The more money we have tied up in receivables, the less money we have
available for research and development, acquisitions, expansion, marketing and other activities to grow our business. Our DSO in receivables for fiscal 2021
improved to 60 days as compared to 65 days in fiscal 2020. This improvement was primarily due to increased collections of past due receivables, primarily
in China, Japan and Europe, improved linearity with a lower concentration of sales in September 2021 compared to September 2020 and the favorable
impact of foreign exchange rates.

Annualized Fourth Quarter Inventory Turns

We calculate annualized fourth quarter inventory turns as cost of sales during the fourth quarter annualized and divided by net inventories at the end of
the fourth quarter. This indicates how well we are managing our inventory levels, with higher inventory turns resulting in more working capital availability
and a higher return on our investments in inventory. Our annualized fourth quarter inventory turns for fiscal 2021 increased to 2.4 turns from 1.9 turns in
fiscal 2020 primarily due to lower inventory levels, primarily in our OLS segment, due to higher flat panel display shipments and higher service parts
demand partially offset by lower inventory provisions for excess and obsolete inventory in certain ILS business units and improved manufacturing
absorption in both segments.

Adjusted EBITDA as a Percentage of Net Sales

We define adjusted EBITDA as operating income adjusted for depreciation, amortization, stock-based compensation expense, restructuring costs, and
certain other non-operating income and expense items, such as merger and acquisition costs. Key initiatives to reach our goals for EBITDA improvements
include utilization of our manufacturing locations in Asia, optimizing our supply chain and continued leveraging of our infrastructure.

We utilize a number of different financial measures, both GAAP and non-GAAP, such as free cash flow and adjusted EBITDA as a percentage of net

sales, in analyzing and assessing our overall business performance, for making operating decisions and for forecasting and planning future periods. We
consider the use of non-GAAP financial measures helpful in assessing our current financial performance and ongoing operations. While we use non-GAAP
financial measures as a tool to enhance our understanding of certain aspects of our financial performance, we do not consider these measures to be a
substitute for, or superior to, the information provided by GAAP financial measures. We provide free cash flow and adjusted EBITDA as

49

a percentage of sales in order to enhance investors' understanding of our ongoing operations. These measures are used by some investors when assessing our
performance.

Coronavirus pandemic (COVID-19)

In December 2019, COVID-19 cases were reported, and in January 2020, the World Health Organization ("WHO") declared it a Public Health

Emergency of International Concern. On February 28, 2020, the WHO raised its assessment of the COVID-19 threat from high to very high at a global level
due to the continued increase in the number of cases and affected countries, and on March 11, 2020, the WHO characterized COVID-19 as a pandemic. In an
effort to contain COVID-19 or slow its spread, governments around the world have enacted various measures from time to time, including orders to close all
businesses not deemed "essential," isolate residents in their homes or places of residence, and practice social distancing at and away from work. These
actions and the global health crisis caused by COVID-19 will continue to negatively impact global business activity, which could negatively affect our
revenue and results of operations. Each of the regions where we generate a majority of our revenue including Asia, Europe, and North America have been
and may continue to be impacted by COVID-19 in the future. The timing and extent of impact related to COVID-19 varies by country and region.

In determining the impact of the COVID-19 pandemic in relation to our net sales, in fiscal 2020 we compared our actual results to our most recently

published forecast and the net sales guidance range communicated in our quarterly earnings call.

50

 
 
 
 
This forecast has been adjusted for known direct impacts to our bookings and net sales from COVID-19 and other factors. Using this criteria, we estimate
that our sales for fiscal 2020 were negatively impacted by the COVID-19 pandemic by approximately $40.0 million. We believe the impact on fiscal 2021
sales was immaterial.

During fiscal 2020 and 2021, the global demand environment was uncertain at times given the effects of COVID-19 on many businesses, including
manufacturing facilities and customer confidence around the world. While we saw a partial recovery in order volumes in China in the latter half of March
and the third quarter of fiscal 2020, this coincided with declining bookings in other regions, particularly in North America, and to a lesser extent in Europe
and other countries in Asia. Beginning in the fourth quarter of fiscal 2020 and continuing in fiscal 2021, we saw global demand recover in all regions and
begin to return to a more normalized demand trend. However, we cannot predict future resurgences of COVID-19, particularly in light of the recent Delta
variant, and the impact that it may have on future demand for our products and services, particularly given the recent shutdown measures taken in certain
countries in Europe and Asia.

Currently, our major production facilities in Europe, Southeast Asia, and the United States remain open. At all of our locations, we have transitioned

from business continuity plans to return-to-operations plans while continuing to maintain high standards of employee safety and sanitization protocols. Our
Return to Operations Plans have a phased approach with the primary focus on employee safety, with a continuing requirement for "working from home" for
other members of our workforce wherever possible. We have vertically integrated manufacturing, and many of the components produced at certain of our
facilities supply other company facilities, are single sourced internally and are not available from third-party suppliers (for example our semiconductor
diodes are manufactured in Sunnyvale, California). While we do maintain a safety stock of critical components at our various locations, the scope, timing,
and duration of various government restrictions to address the COVID-19 pandemic could impact our internal supply chain. We have implemented certain
policy changes to help support our employees impacted by COVID-19. These measures have and will continue to increase the cost of our operations but the
magnitude and length of time of this impact is difficult to quantify at this time and may continue to be difficult to estimate in the future. If our sales are
reduced for an extended period or if our production output falls because of government restrictions, we may be required to reduce payroll-related costs and
other expenses in the future through layoffs or furloughs, even though we have not done so to date.

We continue to experience various supply disruptions throughout the supply chain and are working closely with our supply base to mitigate or remove

constraints as they become known. Supply constraints due to COVID-19 may impact the speed with which we are able to ramp up production if we
experience strong demand on certain products. We also continue to face supply chain constraints primarily related to logistics, including available air cargo
space and higher freight rates. Available cargo space on flights between the U.S. and Europe, and Europe and Asia has been and remains limited as a result
of the impact from COVID-19 and government and business responses to it, and this has increased shipping time and costs. In addition, shipments between
countries have been more severely impacted by COVID-19 and we are experiencing delays due to additional checks at border crossings, including within
Europe and Asia. There has also been sporadic restrictions on individual travel between certain states in the United States of America as well. Government
actions related to COVID-19 come on the heels of trade tensions between the United States and China, which may continue. We believe we have the ability
to meet the near-term demand for our products, but the situation is fluid and subject to change.

We continue to monitor the rapidly evolving conditions and circumstances as well as guidance from international and domestic authorities, including

public health authorities, and we may need to take additional actions based on their recommendations. There is considerable uncertainty regarding the
impact on our business stemming from current measures and potential future measures that could restrict access to our facilities, limit our manufacturing and
support operations, and place restrictions on our workforce, customers, and suppliers. The measures implemented by various authorities related to the
COVID-19 outbreak have caused us to change our business practices including those related to where employees work, the distance between employees in
our facilities, limitations on in-person meetings between employees and with customers, suppliers, service providers, and stakeholders as well as restrictions
on some shipping activities, business travel to domestic and international locations or to attend trade shows, investor conferences and other events. In March
of 2020, we formed a COVID Steering Committee to, among other things, propose, discuss, and implement best practices in response to COVID-19. The
COVID Steering Committee meets weekly and more often if required. All of our executive officers and many of our key senior-level employees are
members of the COVID Steering Committee.

The COVID-19 pandemic has significantly increased worldwide and regional economic uncertainty and decreased demand for our products in many

markets we serve, which could continue for an unknown period of time. In these circumstances, there may be developments outside of our control, including
the length and extent of the COVID-19 outbreak, government-imposed measures and our ability to ship as well as install products and/or service installed
products that may require us to adjust our operating plans. As such, given the dynamic nature of this situation, we cannot estimate with certainty the future
impacts of COVID-19 on our financial condition, results of operations or cash flows. However, we do expect that it could have an adverse impact on our
revenue as well as our overall profitability and could lead to an increase in inventory

51

provisions, allowances for credit losses, and a volatile effective tax rate driven by changes in the mix of earnings across our markets.

See "Risks Related to COVID-19 Pandemic" included under the heading "Risk Factors" in Item 1A of this annual report regarding the impact of

COVID-19.

Goodwill and other impairment charges

Based on our internal projections and the preparation of our financial statements for the quarter ended April 4, 2020, and considering the then-expected

decrease in demand due to the COVID-19 pandemic and other factors, we believed that the fair value of our ILS reporting unit might no longer have
exceeded its carrying value and performed an interim goodwill impairment test on the ILS and OLS reporting units. Based on the estimated fair value of the
ILS reporting unit, we recorded non-cash pre-tax goodwill impairment charges of $327.2 million in the quarter ended April 4, 2020. In addition, we
performed impairment tests on the long-lived assets allocated to the asset group of the ILS reporting unit, including intangible assets, property, plant and
equipment and right of use ("ROU") assets as of April 4, 2020 and recorded non-cash pre-tax charges related to the impairment intangible assets, property,
plant and equipment and ROU assets of the ILS reporting unit of $33.9 million, $85.6 million and $1.8 million, respectively, in the quarter ended April 4,
2020. See Note 8, "Goodwill and Intangible Assets" and Note 11, "Leases" in the Notes to Consolidated Financial Statements under Item 8 of this annual
report.

Restructuring

In June 2019, we announced our plans to exit a portion of our High Power Fiber Laser ("HPFL") business and consolidate all HPFL manufacturing and
engineering functions in our Tampere, Finland facility by transferring certain HPFL activities from our Hamburg, Germany facility. In conjunction with this
announcement, we recorded restructuring charges in fiscal 2019 of $19.7 million. The charges primarily related to write-offs of excess inventory, which is
recorded in cost of sales, and estimated severance. We recorded charges of $1.1 million in fiscal 2020, primarily related to accelerated depreciation and
project management consulting. We recorded no charges related to this project in fiscal 2021 as the project was completed in fiscal 2020.

We also vacated our leased facility in Santa Clara at the end of the lease term on July 31, 2020 and combined operations into our owned Santa Clara
headquarters. We did not incur material expenses in fiscal 2019 related to this project. In fiscal 2021 and 2020, we incurred costs of $0.1 million and $1.5
million, respectively, primarily related to accelerated depreciation, and completed the project in fiscal 2021.

In the fourth quarter of fiscal 2020, we began a restructuring program in our ILS segment which includes management reorganizations, the planned

closure of multiple manufacturing sites, and the right-sizing of global sales, service, order admin, marketing communication and certain administrative
functions, among others. In fiscal 2020, we incurred costs of $2.6 million, primarily related to severance. In fiscal 2021, we incurred costs of $12.2 million,
primarily related to write-offs of excess inventory, accruals for vendor commitments and warranty provisions, which are recorded in cost of sales, estimated
severance, facility exit costs and accelerated depreciation.

See Note 19, "Restructuring Charges" in the Notes to Consolidated Financial Statements under Item 8 of this annual report for further discussion of the

restructuring charges.

Acquisitions

On April 19, 2021, we acquired Electro-Optics Technology, Inc. ("EOT") for approximately $29.3 million, excluding transaction costs. EOT is a

specialized U.S.-based components company, which we expect will enable us to vertically integrate and improve the performance of our directed energy
amplifier technology. See Note 4, "Business Combinations" in the Notes to Consolidated Financial Statements under Item 8 of this annual report.

Net loss for fiscal 2021 was $106.8 million ($4.38 per diluted share). This included after tax charges of $182.3 million for merger and acquisition costs

(primarily due to a termination fee of $217.6 million paid to Lumentum), $36.0 million of after-tax stock-based compensation expense, $10.4 million of
after-tax restructuring costs, $9.3 million of after-tax amortization of intangible assets, $5.3 million of after-tax losses on the dissolution of our OR Laser
operations, $1.1 million of purchase accounting step-up and $13.1 million non-recurring income tax net expense.

Net loss for fiscal 2020 was $414.1 million ($17.18 per diluted share). This included after tax charges of $423.2 million for goodwill and other
impairment, $39.1 million of after-tax stock-based compensation expense, $21.9 million of after-tax amortization of intangible assets, $2.1 million of after-
tax restructuring costs (net of the gain on the sale-leaseback of our Hamburg facility), $0.7 million after-tax of accelerated compensation for our former
CEO, $0.6 million non-recurring income tax net expense and $0.9 million of excess tax benefit for employee stock-based compensation.

Backlog

Backlog represents orders which we expect to be shipped within 12 months and the current portion of service contracts. Orders used to compute
backlog are generally cancellable and, depending on the notice period, are subject to rescheduling by our customers without substantial penalties. We have
not historically experienced a significant rate of cancellation or rescheduling, however the rate of cancellations or rescheduling may increase in the future.

We had a backlog of orders shippable within 12 months of $717.1 million at October 2, 2021.

During fiscal 2021, net sales increased by $258.5 million, or 21%, compared to fiscal 2020, with increases in the microelectronics, instrumentation and
precision manufacturing markets partially offset by decreases in the aerospace and defense market. The increase included higher net sales due to the negative
impact in fiscal 2020 of approximately $40.0 million from COVID-19 shelter-in place orders and/or delays in restarting non-essential manufacturing activity
at many of our customers, primarily in the precision manufacturing, instrumentation and aerospace and defense markets. In fiscal 2020, we continued to
experience weaker demand in the microelectronics and materials processing markets. We finished fiscal 2021 with a positive book-to-bill ratio, in all four
end-markets, and increased backlog levels compared to fiscal 2020 across all end-markets. Entering fiscal 2022, we believe that we are well-positioned with
our laser-based technology to benefit from technology proliferation in rapid growth areas such as 5G, flexible OLED and MicroLED. In addition, we believe
the market for laser-based medical instrumentation, devices and procedures will continue to grow with the aging population around the globe. We also
anticipate that technology advances will result in increased defense spending globally.

During fiscal 2021, microelectronics sales increased $126.0 million, or 23%, compared to fiscal 2020 primarily due to increased shipments for flat
panel display (higher shipments related to ELA tools used in the flat panel display market and higher revenues from consumable service parts), advanced
packaging and semiconductor applications, and partially due to the negative impact of COVID-19 in fiscal 2020. In microelectronics, we expect future
increases in ELA tool shipments as Asian manufacturers improve yields and ramp manufacturing as indicated by the fact that we have received new orders
for these products in fiscal 2021 and we expect many of these orders to ship in fiscal 2022. In addition, it is expected that the handset market will continue to
transition to 5G and newer technologies over time. This technology requires more power from the battery which we expect will result in the handset
manufacturers having to decide between shorter talk times or placement of larger batteries in existing form factors. Since OLED displays are much thinner
than liquid crystal displays (LCD), we believe 5G will increase demand for OLED displays to accommodate larger batteries. In addition, we are seeing
demand for laser solutions for MicroLED pilot production. We believe that these technological demands will allow us to continue to maintain a leadership
position in flat panel display applications. We are also seeing higher demand for semiconductor applications, somewhat tempered by rolling blackouts in
China. Demand is being driven by continuous strength in cloud computing and data centers as well as in advanced packaging applications driven by 5G
demand for smaller geometry, better power management and next generation printed circuit boards.

Precision manufacturing sales increased $63.3 million, or 19%, during fiscal 2021 primarily due to increased sales in materials processing components
and automotive applications, partially offset by lower shipments for machine tools applications. The increase in fiscal 2021 was partially due to the negative
impact of COVID-19 in fiscal 2020, which was not an impact in fiscal 2021. The Purchasing Managers Index ("PMI") is a measure of the prevailing
economic trends in manufacturing, and often correlates to materials processing sales. The manufacturing PMI for the U.S. and Germany rose in the first few
quarters of fiscal 2021, with the U.S. and Germany hitting near record levels, followed by a slight reduction in the fourth quarter of fiscal 2021. The fourth
quarter PMI reduction was partially due to supply chain pressures from extended lead time, rapidly rising materials prices and recent power supply problems
in China. In addition, we saw customer demand for automobiles and production return to pre-COVID-19 levels. Although unfavorably impacted by the
global semiconductor chip shortage, we expect continued strong demand for laser based welding products, especially for battery applications in EVs
(Electronic Vehicles). Medical device manufacturing had record orders in fiscal 2021, with increases in the U.S., China and Europe.

The increase in the instrumentation market of $73.8 million, or 25%, during fiscal 2021 was primarily due to higher shipments for biomedical
instrumentation and scientific applications, as scientific applications shipments were negatively impacted by COVID-19 in fiscal 2020 due to closures of
universities as a result of COVID-19 shelter-in-place orders, as well as higher shipments for medical applications. We supply lasers and optical systems for
biomedical instrumentation applications and our lasers have been used in diagnostic instruments in applications including gene sequencing, biomarker
identification and vaccine development. We expect demand in the scientific and government program applications to continue to fluctuate from quarter to
quarter.

Sales in the aerospace and defense market decreased $4.6 million, or 8%, during fiscal 2021 primarily due to lower optics shipments in defense and

aerospace applications. We anticipate the defense market, especially amplifiers for directed energy and specialty optics for aerospace, to be a multi-year
growth opportunity for us.

The timing for shipments of our higher average selling price ELA tools in the flat panel display market has historically fluctuated and is expected to

continue to fluctuate from quarter-to-quarter due to customer scheduling, market conditions, our ability to manufacture these products and/or availability of
critical component parts and supplies. As a result, the timing to convert orders for these products to net sales will likely fluctuate from quarter-to-quarter.

We have historically generally experienced decreased net sales in the first fiscal quarter compared to other quarters in our fiscal year due to the impact

of time off and business closures at our facilities and those of many of our customers due to year-

54

end holidays. For example, over the past 10 years, excluding certain recovery years, our first fiscal quarter net sales have ranged 2%-17% below the fourth
quarter of the prior fiscal years.

In fiscal 2021 and 2020, one customer accounted for 16% and 17%, respectively, of net sales.

Segments

We are organized into two reportable operating segments: OLS and ILS. While both segments deliver cost-effective, highly reliable photonics
solutions, OLS is focused on high performance laser sources and complex optical sub-systems, typically used in microelectronics manufacturing, medical
diagnostics and therapeutic applications, as well as in scientific research. ILS delivers high performance laser sources, sub-systems and machine tools
primarily used for industrial laser materials processing, serving important end markets like automotive, machine tools, consumer goods and medical device
manufacturing.

Net sales for fiscal 2021 increased $258.5 million, or 21%, compared to fiscal 2020, with increases of $154.7 million, or 20%, in our OLS segment and

increases of $103.8 million, or 22%, in our ILS segment. The fiscal 2021 increases in both OLS and ILS segment sales included increases due to the
favorable impact of foreign exchange rates.

The increase in our OLS segment sales in fiscal 2021, including higher sales due to the negative impact of COVID-19 in fiscal 2020 of approximately

$26.0 million, was primarily due to higher demand for flat panel display applications, with higher revenues from consumable service parts and higher
shipments of ELA tools, as well as higher shipments for biomedical instrumentation and scientific applications in the instrumentation market, semiconductor
applications in the microelectronics market and applications in the precision manufacturing market. The increased sales were partially offset by lower
shipments for applications in the aerospace and defense market.

The increase in our ILS segment sales from fiscal 2020 to fiscal 2021, including higher sales due to the negative impact of COVID-19 in fiscal 2020 of

approximately $14.0 million, was primarily due to higher sales to the precision manufacturing market, primarily for materials processing components and
automotive applications, higher sales for advanced packaging applications within the microelectronics market and higher sales to the instrumentation
market.

Gross Profit

Consolidated

Our gross profit percentage increased by 4.8% to 38.2% in fiscal 2021 from 33.4% in fiscal 2020. The increase included 1.6% lower amortization of

intangibles primarily due to the impairment of ILS intangibles in the second quarter of fiscal 2020, a 0.5% unfavorable impact of higher restructuring costs,
primarily related to the write-off of inventories, severance costs, warranty costs, facility exit costs and accelerated depreciation in fiscal 2021 due to our
planned closure of multiple manufacturing sites, a 0.1% unfavorable impact due to purchase accounting adjustments (inventory step-up in other costs)
related to our acquisition of EOT in April 2021 and 0.1% higher stock-based compensation expense. Excluding the 0.9% favorable net impact of lower
intangibles amortization, higher restructuring costs, higher purchase accounting adjustments and higher stock-based compensation expense, gross profit
percentage increased 3.9% compared to fiscal 2020 primarily due to lower other costs (2.4%) and lower warranty costs (1.5%). Product margins were flat
year over year as a percentage of sales. Other costs, excluding restructuring provisions, were lower primarily due to lower inventory provisions for excess
and obsolete inventory in certain OLS and ILS business units in fiscal 2021 compared to fiscal 2020. The higher excess and obsolete charges in fiscal 2020
were primarily due to the impact of worldwide economic uncertainties on our demand forecasts due to COVID-19. The lower warranty and installation costs
as a percentage of sales were due to fewer warranty events, particularly for our HPFL products sold in China, as well as for fiber components in ILS and
decreased warranty events in the instrumentation and microelectronics markets within OLS. Although total product margins were flat, unfavorable product
margins in OLS resulted from unfavorable mix and average selling prices and the unfavorable impact of the stronger Euro,

55

 
 
which were partially offset by favorable mix and pricing for fiber components and global tools products in ILS. In both segments, the unfavorable impact of
lower capitalized variances resulting from higher sales volumes were partially offset by the favorable absorption of manufacturing costs.

Our gross profit percentage has been and will continue to be affected by a variety of factors including the impact of shipment volumes, product mix,

pricing on volume orders, our ability to manufacture advanced and more complex products, manufacturing efficiencies, excess and obsolete inventory write-
downs, warranty costs, amortization of intangibles, supply chain shortages, pricing by competitors or suppliers, new product introductions, production
volume, customization and reconfiguration of systems, commodity prices and foreign currency fluctuations against the U.S. Dollar, particularly the recent
volatility of the Euro and to a lesser extent, the Japanese Yen and South Korean Won.

OEM Laser Sources

Our OLS gross profit percentage decreased by 0.6% to 45.4% in fiscal 2021 from 46.0% in fiscal 2020 and included a 0.2% unfavorable impact due to
purchase accounting adjustments (0.2% of inventory step-up in other costs) related to our acquisition of EOT in April 2021. The decrease was primarily due
to unfavorable product margins (2.1%) (both mix of product and service revenues and lower average selling prices) and the unfavorable impact of the
stronger Euro against the U.S. Dollar. In addition, the unfavorable impact of lower capitalized variances resulting from higher sales volumes net of the
favorable absorption of manufacturing costs negatively impacted our gross profit percentage. The unfavorable product costs were partially offset by lower
warranty costs (0.8%) due to decreased warranty events in the instrumentation and microelectronics markets and lower other costs (0.7%) primarily due to
lower inventory provisions for excess and obsolete inventory in certain business units as a percentage of sales partially offset by the unfavorable impact of
EOT purchase accounting adjustments.

Industrial Lasers & Systems

Our ILS gross profit percentage increased by 13.7% to 28.2% in fiscal 2021 from 14.5% in fiscal 2020. The increase included 4.2% lower amortization

of intangibles due to the impairment of ILS intangibles in the second quarter of fiscal 2020 and a 1.3% unfavorable impact of higher restructuring costs,
primarily related to the write-off of inventories, severance, warranty and facility exit costs, and accelerated depreciation in fiscal 2021 due to our planned
closure of multiple manufacturing sites. Excluding the net 2.9% favorable impact of lower intangibles amortization and higher restructuring costs, gross
profit percentage increased 10.8% compared to fiscal 2020 primarily due to lower other costs (5.2%) due to lower provisions for excess and obsolete
inventory, favorable product costs (3.5%) and lower warranty and installation costs (2.1%) as a percentage of sales due to fewer warranty events, particularly
for our HPFL products sold in China, and for fiber components products. The higher excess and obsolete charges in fiscal 2020 were primarily due to the
impact of worldwide economic uncertainties on our demand forecasts due to COVID-19. Product costs, net of restructuring costs, were favorable primarily
due to the favorable absorption of manufacturing costs including the impact of restructuring plans initiated in prior periods and favorable mix and pricing for
fiber components and global tools products partially offset by the unfavorable impact of lower capitalized variances resulting from higher sales volumes.

Research and development

Fiscal 2021 research and development ("R&D") expenses increased $8.7 million, or 8%, from fiscal 2020, but decreased to 8.4% of sales, compared to

9.4% in fiscal 2020. The increase in R&D expenses was primarily due to $6.8 million higher

56

 
 
 
employee-related spending, $1.2 million incremental spending due to the acquisition of EOT in April 2021 and $0.9 million higher charges for increases in
deferred compensation plan liabilities. Partially offsetting the increases were $0.1 million lower spending on materials net of the impact of lower customer
reimbursements and $0.1 million lower stock-based compensation expense. The higher employee-related spending was primarily due to higher variable
compensation, the unfavorable impact of foreign exchange rates and higher severance costs partially offset by the impact of an extra week in fiscal 2020.

On a segment basis as compared to fiscal 2020, OLS R&D spending increased $6.1 million in fiscal 2021 with higher employee-related spending, the

unfavorable impact of foreign exchange rates and incremental spending from the acquisition of EOT partially offset by lower net spending on materials. ILS
R&D spending increased $1.8 million primarily due to higher employee-related spending and the unfavorable impact of foreign exchange rates partially
offset by lower net spending on materials. Corporate and other R&D spending increased $0.8 million primarily due to higher charges for increases in
deferred compensation plan liabilities partially offset by lower stock-based compensation expense.

Selling, general and administrative

Fiscal 2021 selling, general and administrative ("SG&A") expenses increased $33.4 million, or 12%, from fiscal 2020. The increase was primarily due

to $31.3 million higher employee-related spending, $3.3 million higher other variable spending, $2.9 million higher charges for increases in deferred
compensation plan liabilities and $1.6 million incremental spending due to the acquisition of EOT in April 2021, partially offset by $5.7 million lower stock-
based compensation expense. The $31.3 million higher employee-related spending was primarily due to higher variable compensation, the unfavorable
impact of foreign exchange rates and higher sales commissions partially offset by the impact of an extra week in fiscal 2020, the impact of lower headcount
and lower costs related to the retirement of and transition of our former CEO to special advisor status. The $3.3 million higher other variable spending
included higher consulting on special projects, the non-recurrence of a gain on the sale-leaseback of our Hamburg facility in fiscal 2020, the unfavorable
impact of foreign exchange rates, the impact of a benefit in fiscal 2020 of amounts received from a $1.4 million legal settlement on a resolved asset recovery
matter and higher sales rep commissions partially offset by lower travel and other discretionary spending due to COVID-19 and lower bad debts expense.
The $5.7 million lower stock-based compensation expense is primarily due to lower accounting acceleration charges for equity grants for our former CEO
and other executives partially offset by increased equity grants to our employees, including our executives.

On a segment basis as compared to fiscal 2020, OLS SG&A expenses increased $14.6 million primarily due to higher employee-related spending, the

unfavorable impact of foreign exchange rates and the acquisition of EOT partially offset by lower variable spending on travel and other discretionary
spending. ILS SG&A spending increased $12.3 million primarily due to higher employee-related spending including the favorable impact of lower
headcount, the unfavorable impact of foreign exchange rates, the prior year gain on the sale-leaseback of our Hamburg facility and the prior year settlement
on the resolved asset recovery matter partially offset by lower variable spending on travel and other discretionary spending. Corporate and other SG&A
spending increased $6.5 million primarily due to higher employee-related spending (including higher variable compensation), higher charges for increases in
deferred compensation plan liabilities and higher consulting fees partially offset by lower stock-based compensation expense, lower costs related to the
retirement of our former CEO.

Merger and acquisition costs

In fiscal 2021, we recorded $236.0 million in merger and acquisition costs, including $217.6 million paid to Lumentum as a termination fee, as well as

costs for investment banking, legal and other consultants related to our merger agreements with Lumentum and II-VI and other acquisition-related costs.

Goodwill and other impairment charges

In fiscal 2020, we recorded non-cash pre-tax goodwill impairment charges of $327.2 million related to our ILS segment to operating expense in our
results of operations. In addition, we recorded non-cash pre-tax charges related to the impairment of intangible assets, property, plant and equipment and
ROU assets of the ILS reporting unit of $33.9 million, $85.6 million and $1.8 million, respectively. See Note 8, "Goodwill and Intangible Assets" in the
Notes to Consolidated Financial Statements and Note 11, "Leases" in the Notes to Consolidated Financial Statements under Item 8 of this annual report.

In fiscal 2019, we invested 3.0 million Euros ($3.4 million) in 3D-Micromac AG, a private company in Germany. The investment is included in other
assets and is being carried on a cost basis. During fiscal 2020, we determined that our investment became impaired and wrote it down to its fair value. As a
result, we recorded a non-cash impairment charge of $2.5 million to operating expense in our results of operations in fiscal 2020.

Amortization of intangible assets

57

Amortization of intangible assets decreased $1.1 million, or 28%, from fiscal 2020 to fiscal 2021 primarily due to the impairment of ILS intangibles in

fiscal 2020 and the completion of the amortization of certain intangibles from acquisitions partially offset by the unfavorable impact of foreign exchange
rates and the acquisition of EOT in April 2021.

Other income (expense), net

Other income (expense), net, increased by $4.8 million to other expense of $17.3 million in fiscal 2021 from other expense of $12.5 million in fiscal

2020. The higher expenses were primarily due to the $5.3 million non-recurring translation adjustment related to the dissolution of our OR Laser operations,
$1.5 million higher foreign exchange losses, $1.0 million higher interest expense due to the unfavorable impact of foreign exchange rates and $0.6 million
lower interest income partially offset by $3.7 million higher gains, net of expenses, on our deferred compensation plan assets.

Income taxes

Our effective tax rate on loss before income taxes for fiscal 2021 of 7.6% was lower than the U.S. federal tax rate of 21%. Our effective tax rate benefit

for fiscal 2021 was unfavorably impacted primarily due to the establishment of valuation allowances on certain deferred tax assets, income in foreign
jurisdictions subject to tax rates that are higher than the U.S. tax rates, stock-based compensation not deductible for tax purposes and limitations on the
deductibility of compensation under Internal Revenue Code Section 162(m) and the deferred taxes on foreign earnings not considered permanently
reinvested, partially offset by the benefit of federal research and development tax credits, our Singapore tax exemption and the benefit of our FDII
deduction.

Our results reflect the payment of a termination fee to Lumentum of $217.6 million in the second quarter of fiscal 2021. This amount was deducted for

book purposes in the current year and treated as a future deductible expense for tax purposes in accordance with our accounting policy.

Our effective tax rate on loss before income taxes for fiscal 2020 of 6.5% was lower than the U.S. federal tax rate of 21%. Our effective tax rate benefit

for fiscal 2020 was unfavorably impacted primarily due to the impairment of goodwill that is not deductible for tax purposes and the establishment of
valuation allowances for certain deferred tax assets. These unfavorable impacts were partially offset primarily from the release of unrecognized tax benefits
net of settlements and competent authority offsets and losses in foreign jurisdictions subject to tax rates that are higher than the U.S. tax rates.

In September 2021, Coherent Singapore received an amended Pioneer Status tax exemption from the Singapore authorities effective from fiscal 2022

through fiscal 2026. The tax holiday continues to be conditional upon our meeting certain revenue, business spending and employment thresholds. The
impact of this tax exemption decreased Coherent Singapore income taxes by approximately $3.7 million and $2.6 million in fiscal 2021 and 2020,
respectively. The benefits of the tax holiday on net income per diluted share were $0.15 and $0.11, respectively.

FINANCIAL CONDITION

Liquidity and capital resources

At October 2, 2021, we had assets classified as cash and cash equivalents and short-term investments, in an aggregate amount of $456.5 million,
compared to $475.6 million at October 3, 2020. In addition, at October 2, 2021, we had $6.0 million of restricted cash. At October 2, 2021, approximately
$310.6 million of our cash and securities was held in certain of our foreign subsidiaries and branches, $291.7 million of which was denominated in
currencies other than the U.S. Dollar. Our foreign subsidiaries loaned approximately $124.3 million of funds to Coherent, Inc. to pay a termination fee of
$217.6 million to Lumentum in March 2021. Our current business plans do not demonstrate a need for additional foreign funds to support our domestic
operations and it is our intention to repay our borrowings to our foreign subsidiaries. If, however, a portion of these foreign funds are needed for and
distributed to our operations in the United States via a dividend, we may be subject to additional foreign withholding taxes and certain state taxes. The
amount of the U.S. and foreign taxes due would depend on the amount and manner of repatriation, as well as the location from where the funds are
repatriated. We historically asserted our intention to indefinitely reinvest foreign earnings. As a result of the enactment of the Tax Act and certain income tax
treaty updates, we no longer consider foreign earnings to be indefinitely reinvested in our foreign subsidiaries. We actively monitor the third-party
depository institutions that hold these assets, primarily focusing on the safety of principal and secondarily maximizing yield on these assets. We diversify
our cash and cash equivalents and investments among various financial institutions, money market funds, sovereign debt and other securities in order to
reduce our exposure should any one of these financial institutions or financial instruments fail or encounter difficulties. To date, we have not experienced
any material loss or lack of access to our invested cash, cash equivalents or short-term investments. However, we can provide no assurances that access to
our invested cash, cash equivalents or short-term investments will not be impacted by adverse conditions in the financial markets. To date, we have had
sufficient liquidity to manage the financial impact of COVID-19. However, we can provide no assurance that this will continue to be the case if the impact
of COVID-19 is prolonged or if there is an extended

58

impact on us or the economy in general. Further, COVID-19 has caused significant uncertainty and volatility in the credit markets. If our liquidity or access
to capital becomes significantly constrained, or if costs of capital increase significantly due to the impact of COVID-19 as result of a volatility in the capital
markets, a reduction in our creditworthiness or other factors, then our financial condition, results of operations and cash flows could be materially adversely
affected.

See ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK below for more information about risks and trends

related to foreign currencies.

Sources and Uses of Cash

Historically, our primary source of cash has been provided by operations. Other sources of cash in the past few fiscal years include proceeds from our
Euro Term Loan used to finance our acquisition of Rofin, proceeds received from the sale of our stock through our employee stock purchase plan as well as
borrowings under our Revolving Credit Facility and for the construction of a facility in Germany. Our historical uses of cash have primarily been for
acquisitions of businesses and technologies, the repurchase of our common stock, merger and acquisition costs, the purchases of property and equipment and
debt issuance costs. Supplemental information pertaining to our historical sources and uses of cash is presented as follows and should be read in conjunction
with our Consolidated Statements of Cash Flows and notes thereto (in thousands):

Net cash provided by operating activities decreased by $134.0 million in fiscal 2021 compared to fiscal 2020. The decrease in cash provided by

operating activities in fiscal 2021 was primarily due to lower net income including the $217.6 million termination fee paid to Lumentum, non-cash
adjustments and lower cash flows from accounts receivable and deferred taxes, partially offset by higher cash flows from income taxes payable, accounts
payable and other current liabilities. In order to support our liquidity during the pandemic, we have and will continue to take measures to increase available
cash on hand, including, but not limited to, reducing discretionary spending for operating and capital expenses. To further support our liquidity, we elected to
defer the payment of our employer portion of social security taxes beginning in April 2020 and through the end of calendar 2020, which we expect to pay in
equal installments in the first quarters of fiscal 2022 and 2023, as provided for under the CARES Act. We believe that our existing cash, cash equivalents
and short term investments combined with cash to be provided by operating activities will be adequate to cover our working capital needs and planned
capital expenditures for at least the next 12 months to the extent such items are known or are reasonably determinable based on current business and market
conditions, including consideration of the impact of COVID-19, and will be adequate to support our long-term liquidity needs. However, we may elect to
finance certain of our capital expenditure requirements through other sources of capital. As of October 2, 2021, in the ordinary course of business, we had
total estimated significant purchase commitments for inventory from our suppliers of approximately $63.8 million and significant purchase obligations for
fixed assets and services of $50.6 million. In addition, as of October 2, 2021, we had obligations under our operating leases of approximately $99.5 million,
$18.3 million of which will be paid in the next 12 months. We continue to follow our strategy to further strengthen our financial position by using available
cash flow to fund operations.

We intend to continue to consider acquisition opportunities at valuations we believe are reasonable based upon market conditions. However, we cannot
accurately predict the timing, size and success of our acquisition efforts or our associated potential capital commitments. Furthermore, we cannot assure you
that we will be able to acquire businesses on terms acceptable to us. We expect to fund future acquisitions, if any, through existing cash balances and cash
flows from operations (as in our acquisition of EOT) and additional borrowings (as in our acquisition of Rofin). If required, we will consider the issuance of
securities. The extent to which we will be willing or able to use our common stock to make acquisitions will depend on its market value at the time and the
willingness of potential sellers to accept it as full or partial payment. On April 19, 2021, we acquired EOT for approximately $29.3 million in cash.

In fiscal 2020, we made debt principal payments of $7.5 million, recorded interest expense on the Euro Term Loan of $12.3 million and recorded $3.3

million amortization of debt issuance costs. In fiscal 2020, we recorded interest expense related to our Revolving Credit Facility of $0.6 million.

59

 
 
In fiscal 2021, we made debt principal payments of $8.0 million, recorded interest expense on the Euro Term Loan of $12.9 million and recorded $3.5

million amortization of debt issuance costs. In fiscal 2021, we recorded interest expense related to our Revolving Credit Facility of $0.4 million.

On March 25, 2021, we paid a termination fee of $217.6 million to Lumentum.

Additional sources of cash available to us, in addition to the amounts available under the Revolving Credit Facility, were international currency lines of
credit and bank credit facilities totaling $15.0 million as of October 2, 2021, of which $13.1 million was unused and available. These unsecured international
credit facilities were used in Europe during fiscal 2021. As of October 2, 2021, we had utilized $1.9 million of the international credit facilities as guarantees
in Europe.

On October 29, 2021, we entered into a 10.0 million Euro letter of credit facility, rolled our existing letter of credit into that facility and deposited 10.5

million Euros with Barclays as cash collateral to secure the payment obligations under such facility, resulting in restricted cash of $12.2 million.

On October 29, 2021, we repaid the $10.0 million outstanding under the Revolving Credit Facility and the facility expired on November 5, 2021.

Our ratio of current assets to current liabilities decreased to 3.1:1 at October 2, 2021 compared to 4.5:1 at October 3, 2020. The decrease in our ratio

was primarily due to higher other current liabilities, higher accounts payable, higher income taxes payable and lower inventories. Our cash and cash
equivalents, short-term investments and working capital are as follows (in thousands):

Changes in financial condition

Cash provided by operating activities in fiscal 2021 was $72.9 million, which included cash provided by operating assets and liabilities of $99.0
million (primarily higher accounts payable, higher accrued payroll, lower inventories and higher income taxes payable net of higher accounts receivable),
depreciation and amortization of $55.0 million, stock-based compensation expense of $41.4 million, amortization of operating right of use ("ROU") assets of
$19.2 million, non-cash restructuring charges of $5.6 million, non-cash loss on dissolution of our OR Laser operations of $5.3 million and amortization of
debt issuance cost of $3.5 million partially offset by net loss of $106.8 million (including the $217.6 million termination fee paid to Lumentum) and net
increases in deferred tax assets of $50.6 million. Cash provided by operating activities in fiscal 2020 was $206.9 million, which included non-cash goodwill
and other impairment charges of $451.0 million, depreciation and amortization of $76.8 million, cash provided by operating assets and liabilities of $51.8
million (primarily lower accounts receivable, lower inventories and higher accounts payable net of lower income taxes payable and payments made for lease
liabilities), stock-based compensation expense of $44.8 million, amortization of operating ROU assets of $16.0 million, amortization of debt issue costs of
$3.3 million and non-cash restructuring charges of $2.2 million, partially offset by net loss of $414.1 million and net increases in deferred tax assets of $24.5
million.

Cash used in investing activities in fiscal 2021 was $72.9 million, which included $79.4 million, net of proceeds from dispositions, used to acquire

property and equipment and to purchase and upgrade buildings and $28.8 million, net of cash acquired, used to purchase EOT partially offset by $35.3
million net maturities of available-for-sale securities. Cash used in investing activities in fiscal 2020 was $78.2 million, which included $43.0 million, net of
proceeds from dispositions including $21.5 million received from the sale-leaseback of our Hamburg facility, used to acquire property and equipment and to
purchase and upgrade buildings and $35.2 million net purchases of available-for-sale securities.

Cash provided by financing activities in fiscal 2021 was $20.6 million, which included $18.4 million net debt borrowings and $12.5 million generated

from our employee stock purchase plan partially offset by $10.4 million in outflows due to net settlement of restricted stock units. Cash used in financing
activities in fiscal 2020 was $9.9 million, which included $13.5 million in outflows due to net settlement of restricted stock units and $9.7 million net debt
payments partially offset by $13.4 million generated from our employee stock option and purchase plans.

60

 
 
Changes in exchange rates in fiscal 2021 resulted in a decrease in cash balances of $3.7 million. Changes in exchange rates in fiscal 2020 resulted in an

increase in cash balances of $8.0 million.

RECENT ACCOUNTING PRONOUNCEMENTS

See Note 2, "Significant Accounting Policies" in the Notes to Consolidated Financial Statements under Item 8 of this annual report for a full

description of recent accounting pronouncements, including the respective dates of adoption or expected adoption and effects on our consolidated financial
position, results of operations and cash flows.

APPLICATION OF CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our discussion and analysis of financial condition and results of operations are based upon our consolidated financial statements, which have been

prepared in accordance with accounting principles generally accepted in the United States of America and pursuant to the rules and regulations of the SEC.
The preparation of these consolidated financial statements 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 consolidated financial statements and the reported amounts of
revenues and expenses during the reporting period. We have identified the following as the items that require the most significant judgment and often
involve complex estimation: revenue recognition, business combinations, accounting for long-lived assets (including goodwill and intangible assets),
inventory valuation, warranty reserves and accounting for income taxes.

Revenue Recognition

Revenue is recognized when transfer of control to the customer occurs in an amount reflecting the consideration that we expect to be entitled. We

determine revenue recognition by applying the following five-step approach: (1) identification of the contract, or contracts, with a customer; (2)
identification of the performance obligations in the contract; (3) determination of the transaction price; (4) allocation of the transaction price to the
performance obligations in the contract; and (5) recognition of revenue when, or as, we satisfy each performance obligation.

The transaction price is determined based on the consideration to which we will be entitled in exchange for transferring goods or services to the
customer adjusted for estimated variable consideration, if any, as more fully described in Note 2, "Significant Accounting Policies - Revenue Recognition,"
in the Notes to Consolidated Financial Statements under Item 8 of this annual report. The majority of products and services offered by us have readily
observable selling prices. As a part of our stand-alone selling price policy, we review product pricing on a periodic basis to identify any significant changes
and revise our expected selling price assumptions as appropriate. Revenue is generally recognized when control of the product is transferred to the customer
(i.e., when our performance obligation is satisfied), which typically occurs at shipment but which can occur over time for certain of our maintenance,
extended warranty or custom product contracts. When goods or services have been delivered to the customer, but all conditions for revenue recognition have
not been met, deferred revenue and deferred costs are recorded on our consolidated balance sheet. Recognizing revenue over time also includes an
estimation of the progress towards completion based on the projected costs for the contract.

Business Combinations

We include the results of operations of the businesses that we acquire as of the respective dates of acquisition. We allocate the fair value of the
purchase price of our business acquisitions to the tangible assets acquired, liabilities assumed, and intangible assets acquired, based on their estimated fair
values. The excess of the purchase price over the fair values of these identifiable assets and liabilities is recorded as goodwill. Additional information
existing as of the acquisition date, but unknown to us at that time, may become known during the remainder of the measurement period, not to exceed 12
months from the acquisition date, which may result in changes to the amounts and allocations recorded.

Long-Lived Assets and Goodwill

We evaluate long-lived assets and amortizable intangible assets whenever events or changes in business circumstances or our planned use of assets
indicate that their carrying amounts may not be fully recoverable or that their useful lives are no longer appropriate. Reviews are performed to determine
whether the carrying values of the assets are impaired based on comparison to the undiscounted expected future cash flows identifiable to such long-lived
and amortizable intangible assets. If the comparison indicates that impairment exists, the impaired asset is written down to its fair value.

We have determined that our reporting units are the same as our operating segments as each constitutes a business for which discrete financial

information is available and for which segment management regularly reviews the operating results. We make this determination in a manner consistent with
how the operating segments are managed. Based on this analysis, we have identified two reporting units which are our reportable segments: OLS and ILS.

61

Goodwill is tested for impairment on an annual basis and between annual tests in certain circumstances, and written down when impaired. We
generally perform our annual impairment tests during the fourth quarter of each fiscal year using the opening balance sheet as of the first day of the fourth
fiscal quarter, with any resulting impairment recorded in the fourth quarter of the fiscal year.

See Note 8, "Goodwill and Intangible Assets" in the Notes to Consolidated Financial Statements under Item 8 of this annual report for discussion of
the non-cash pre-tax charges we recorded in the quarter ended April 4, 2020 related to the goodwill, intangible assets, property, plant and equipment and
ROU assets of the ILS reporting unit of $327.2 million, $33.9 million, $85.6 million and $1.8 million, respectively.

For our annual impairment test in fiscal 2020 and 2021, for our OLS reporting unit we conducted a qualitative assessment of the goodwill during the

fourth quarter using the opening balance sheet as of the first day of the fourth quarter and concluded that it was more likely than not that the fair value of the
reporting unit exceeded its carrying amounts. In assessing the qualitative factors, we considered the impact of these key factors: macroeconomic conditions,
fluctuations in foreign currency, market and industry conditions, our operating and competitive environment, regulatory and political developments, the
overall financial performance of our reporting units including cost factors and budgeted-to-actual revenue results. We also considered our market
capitalization, stock price performance and the significant excess calculated in the second quarter of fiscal 2020 between estimated fair value and the
carrying value of OLS. Based on our assessment, goodwill in the OLS reporting unit was not impaired as of the first day of the fourth quarter of fiscal 2020
or 2021. As such, it was not necessary to perform the goodwill impairment test in the fourth quarter of fiscal 2020 or 2021. There is no goodwill in the ILS
reporting unit due to the impairment of all goodwill of the ILS reporting unit in the second quarter of fiscal 2020.

At October 2, 2021, we had $105.3 million of goodwill, $14.7 million of purchased intangible assets and $302.6 million of property and equipment on

our consolidated balance sheet.

Inventory Valuation

We record our inventory at the lower of cost (computed on a first-in, first-out basis) or net realizable value. We write-down our inventory to its
estimated market value based on assumptions about future demand and market conditions. Inventory write-downs are generally recorded within guidelines
set by management when the inventory for a device exceeds 12 months of its demand or when management has deemed parts are no longer active or useful.
If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required which could
materially affect our future results of operations. Due to rapidly changing forecasts and orders, additional write-downs for excess or obsolete inventory,
while not currently expected, could be required in the future. In the event that alternative future uses of fully written down inventories are identified, we may
experience better than normal profit margins when such inventory is sold. Differences between actual results and previous estimates of excess and obsolete
inventory could materially affect our future results of operations. We write-down our demo inventory by amortizing the cost of demo inventory over periods
ranging from 24 to 36 months after such inventory is placed in service.

Warranty Reserves

We provide warranties on the majority of our product sales and allowances for estimated warranty costs are recorded during the period of sale. The

determination of such allowances requires us to make estimates of product return rates and expected costs to repair or replace the products under warranty.
We currently establish warranty reserves based on historical warranty costs for each product line. The weighted average warranty period covered is
approximately 15 to 18 months. If actual return rates and/or repair and replacement costs differ significantly from our estimates, adjustments to cost of sales
may be required in future periods.

Income Taxes

As part of the process of preparing our consolidated financial statements, we are required to estimate our income tax provision (benefit) in each of the

jurisdictions in which we operate. This process involves us estimating our current income tax provision (benefit) together with assessing temporary
differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which
are included within our consolidated balance sheets.

We record a valuation allowance to reduce our deferred tax assets to an amount that more likely than not will be realized. While we have considered

future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance, in the event we were to
determine that we would be able to realize our deferred tax assets in the future in excess of our net recorded amount, an adjustment to the allowance for the
deferred tax asset would increase income in the period such determination was made. Likewise, should we determine that we would not be able to realize all
or part of our

62

net deferred tax asset in the future, an adjustment to the valuation allowance for the deferred tax asset would be charged to income in the period such
determination was made.

During fiscal 2021, we increased our valuation allowance on deferred tax assets by $15.5 million to $73.2 million, primarily due to the net operating
losses generated from certain foreign entities, California and certain state research and development tax credits which are not expected to be recognized. As
of October 2, 2021, we had U.S. federal deferred tax assets related to research and development credits and other tax attributes that can be used to offset
federal taxable income in future periods. These credit carryforwards will expire if they are not used within certain time periods. Management determined
that there is sufficient positive evidence to conclude that it is more likely than not sufficient taxable income will exist in the future allowing us to recognize
these deferred tax assets.

We historically asserted our intention to indefinitely reinvest foreign earnings. As a result of the enactment of the Tax Act and certain foreign tax law
changes, we no longer consider foreign earnings to be indefinitely reinvested in our foreign subsidiaries. As a result of this change in assertion, we recorded
a $18.4 million tax expense against our foreign earnings that are not indefinitely reinvested as of fiscal 2021. This is mainly related to foreign withholding
taxes and state income taxes. We have not recognized any deferred taxes for outside basis differences in foreign subsidiaries.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk disclosures

We are exposed to market risk related to changes in interest rates and foreign currency exchange rates. We do not use derivative financial instruments

for speculative or trading purposes.

Interest rate sensitivity

A portion of our investment portfolio is composed of fixed income securities. These securities are subject to interest rate risk and will fall in value if

market interest rates increase. If interest rates were to increase immediately (whether due to changes in overall market rates or credit worthiness of the
issuers of our individual securities) and uniformly by 10% from levels at fiscal 2021 year-end, the fair value of the portfolio, based on quoted market prices
in active markets involving similar assets, would decline by an immaterial amount due to their short-term maturities. We have the ability to generally hold
our fixed income investments until maturity and therefore we would not expect our operating results or cash flows to be affected to any significant degree by
the effect of a sudden change in market interest rates on our securities portfolio. If necessary, we may sell short-term investments prior to maturity to meet
our liquidity needs.

At fiscal 2021 year-end, we had no available-for-sale debt securities. At fiscal 2020 year-end, the fair value of our available-for-sale debt securities was

$35.3 million, which was classified as short-term investments. Gross unrealized gains and losses on available-for-sale debt securities were $36,000 and
$(1,000), respectively, at fiscal 2020 year-end.

We are exposed to market risks related to fluctuations in floating interest rates related to our Euro Term Loan. As of October 2, 2021, we owed $407.2

million on this loan, which had an interest rate of 3.0% as of October 2, 2021. We performed a sensitivity analysis on the outstanding portion of our debt
obligation as of October 2, 2021. Should the current average interest rate increase or decrease by 10%, the resulting annual increase or decrease to interest
expense would be approximately $1.2 million as of October 2, 2021.

Foreign currency exchange risk

We maintain operations in various countries outside of the United States and have foreign subsidiaries that manufacture and sell our products in
various global markets. The majority of our sales are transacted in U.S. Dollars. However, we do generate revenues in other currencies, primarily the Euro,
Chinese Renminbi, South Korean Won, Japanese Yen, and British Pound. Additionally, we have operations in different countries around the world with costs
incurred in the foregoing currencies and other local currencies, such as British Pound Sterling, Malaysian Ringgit, Swiss Franc, Taiwan Dollar, Swedish
Krona, Canadian Dollar and Vietnamese Dong. As a result, our earnings, cash flows and cash balances are exposed to fluctuations in foreign currency
exchange rates. For example, because of our significant manufacturing operations in Europe and resulting expenses and costs, a weakening Euro is
advantageous and a strengthening Euro is disadvantageous to our financial results. We attempt to limit these exposures through financial market instruments.
We utilize derivative instruments, primarily forward contracts with maturities of two months or less, to manage our exposure associated with net asset and
liability positions denominated in foreign currencies. Gains and losses on the forward contracts are mitigated by gains and losses on the underlying
instruments. We do not use derivative financial instruments for trading purposes.

We do not anticipate any material adverse effect on our consolidated financial position, results of operations or cash flows resulting from the use of

these instruments. There can be no assurance that these strategies will be effective or that transaction

63

losses can be minimized or forecasted accurately. While we model currency valuations and fluctuations, these may not ultimately be accurate. If a financial
counterparty to any of our hedging arrangements experiences financial difficulties or is otherwise unable to honor the terms of the foreign currency hedge,
we may experience material financial losses. In the current economic environment, the risk of failure of a financial party remains high.

A hypothetical 10% change in foreign currency rates on our forward contracts would not have a material impact on our results of operations, cash
flows or financial position. For example, a 10% change in the Euro as of October 2, 2021 would amount to less than a 0.7% change on our consolidated
balance sheet.

At October 2, 2021, approximately $310.6 million of our cash, cash equivalents and short-term investments were held outside the U.S. in certain of our

foreign operations, $291.7 million of which was denominated in currencies other than the U.S. Dollar.

See Note 7, "Derivative Instruments and Hedging Activities" in our Notes to Consolidated Financial Statements under Item 8 of this annual report for

further discussion of our derivatives and hedging activities.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Coherent, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Coherent, Inc. and subsidiaries (the "Company") as of October 2, 2021 and
October 3, 2020, the related consolidated statements of operations, comprehensive income (loss), stockholders' equity, and cash flows, for each of the three
years in the period ended October 2, 2021, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial
statements present fairly, in all material respects, the financial position of the Company as of October 2, 2021 and October 3, 2020, and the results of its
operations and its cash flows for each of the three years in the period ended October 2, 2021, in conformity with accounting principles generally accepted in
the United States of America.

We have also 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 October 2, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by
the Committee of Sponsoring Organizations of the Treadway Commission and our report dated November 29, 2021, expressed an unqualified opinion on the
Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial
statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company
in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing
procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to
those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also
included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the
financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or

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

Deferred Tax Assets – Valuation Allowance - Refer to Notes 2 and 16 to the consolidated financial statements

Critical Audit Matter Description

The Company recognizes deferred tax assets to the extent that it is expected that these assets are more likely than not to be realized. The Company
evaluates the realizability of the deferred tax assets, and to the extent that the Company estimates that it is more likely than not that a benefit will not be
realized, the carrying amount of the deferred tax assets is reduced by a valuation allowance. As part of this evaluation, the Company assesses all available
positive and negative evidence to determine whether sufficient future taxable income will be generated to realize existing deferred tax assets. As of
October 2, 2021, total deferred tax assets were $244.9 million, which were offset by valuation allowances of $73.2 million. The Company has not recorded a
valuation allowance against its U.S. federal deferred tax assets.

We identified the valuation of U.S. federal deferred tax assets as a critical audit matter because of the significant judgments made by management in

determining whether it was more likely than not that such deferred tax assets would be realized.

Our audit procedures required a high degree of auditor judgment and an increased extent of effort, including the need to involve our income tax

specialists, to evaluate the reasonableness of management’s conclusions.

66

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to management’s assertion that it is more likely than not that the U.S. federal deferred tax assets will be realized included

the following, among others:

• We tested the design and effectiveness of internal controls over the determination of whether it is more likely than not that the deferred tax assets will

be realized.

• With the assistance of our income tax specialists, we:

•

•

•

assessed the completeness and accuracy of the evidence, and the objectivity of such evidence, that the Company considered in making its
determination of the valuation allowance.

considered whether management’s conclusion that certain costs incurred in the prior three-year period, including the termination fee paid to
Lumentum Holdings, Inc. in 2021 and certain impairment charges recorded in 2020, could reasonably be considered to be nonrecurring for
purposes of assessing the historical profitability of the U.S. federal tax jurisdiction.

obtained and tested management’s analysis showing the expected timing of future reversals of deferred tax assets, compared to forecasts of
future taxable income in the U.S. federal tax jurisdiction, and compared the forecasted income used in this analysis to the average income in
the three most recent fiscal years, after adjusting for nonrecurring items.

2. SIGNIFICANT ACCOUNTING POLICIES

Fiscal Year

Our fiscal year ends on the Saturday closest to September 30. Fiscal years 2021, 2020, and 2019 ended on October 2, 2021, October 3, 2020, and
September 28, 2019, respectively, and are referred to in these financial statements as fiscal 2021, fiscal 2020, and fiscal 2019 for convenience. Fiscal 2021
and 2019 each included 52 weeks and fiscal 2020 included 53 weeks. The fiscal years of several of our international subsidiaries end on September 30.
Accordingly, the financial statements of these subsidiaries as of that date and for the years then ended have been used for our consolidated financial
statements. Management believes that the impact of the use of different year-ends is immaterial to our consolidated financial statements taken as a whole.

Use of Estimates

The preparation of consolidated financial statements in conformity with Generally Accepted Accounting Principles ("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
consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those
estimates.

Basis of Presentation

The consolidated financial statements include the accounts of Coherent, Inc. and its direct and indirect subsidiaries (collectively, the "Company," "we,"

"our," "us" or "Coherent"). Intercompany balances and transactions have been eliminated.

Business Combinations

We include the results of operations of the businesses that we acquire as of the respective dates of acquisition. We allocate the fair value of the
purchase price of our business acquisitions to the tangible assets acquired, liabilities assumed, and intangible assets acquired, based on their estimated fair
values. The excess of the purchase price over the fair values of these identifiable assets and liabilities is recorded as goodwill.

On April 19, 2021, we acquired Electro-Optics Technology, Inc. ("EOT") and its subsidiary in Germany. The significant accounting policies of EOT

have been aligned to conform to those of Coherent, and the consolidated financial statements include the results of EOT as of its acquisition date.

Fair Value of Financial Instruments

The carrying amounts of certain of our financial instruments including accounts receivable, accounts payable, and accrued liabilities approximate fair
value due to their short maturities. Short-term investments are comprised of available-for-sale securities, which are carried at fair value. Other non-current
assets include trading securities and life insurance contracts related to our deferred compensation plans; trading securities are carried at fair value and life
insurance contracts are carried at cash surrender values, which due to their ability to be converted to cash at that amount, approximate their fair values.
Foreign exchange contracts are stated at fair value based on prevailing financial market information. Short-term and long-term debt is carried at amortized
cost, which approximates its fair value based on borrowing rates currently available to us for loans with similar terms.

Cash Equivalents

All highly liquid investments with maturities of three months or less at the time of purchase are classified as cash equivalents. At fiscal 2021 year-end,

cash and cash equivalents included cash, money market funds, and time deposits.

Concentration of Credit Risk

Financial instruments that may potentially subject us to concentrations of credit risk consist principally of cash equivalents, short-term investments,

and accounts receivable. At fiscal 2021 year-end, all of our short-term investments were in cash and cash equivalents. Cash equivalents and short-term
investments are maintained with several financial institutions and may exceed the amount of insurance provided on such balances. At October 2, 2021, we
held cash and cash equivalents and short-term investments outside the U.S. in certain of our foreign operations totaling approximately $310.6 million,
$291.7 million of which was denominated in currencies other than the U.S. Dollar. The majority of our accounts receivable are derived from sales to
customers for commercial applications. We perform ongoing credit evaluations of our customers' financial condition and limit the amount of credit extended
when deemed necessary but generally require no collateral. In certain instances, we may require customers to issue a letter of credit. We maintain reserves
for potential credit losses. Our products are broadly distributed and there was one customer who accounted for 17.8% and 24.2% of accounts receivable at
fiscal 2021 and fiscal 2020 year-end, respectively.

Derivative Financial Instruments

Our primary objective for holding derivative financial instruments is to manage currency exchange rate risk. Principal currencies hedged include the
Euro, South Korean Won, Japanese Yen, Chinese Renminbi, Singapore Dollar, British Pound, Malaysian Ringgit, Swiss Franc, Canadian Dollar, Swedish
Krona, Taiwan Dollar, and Vietnamese Dong. Our derivative financial instruments are recorded at fair value, on a gross basis, and are included in other
current assets and other current liabilities.

Our accounting policies for derivative financial instruments are based on whether they meet the criteria for designation as a cash flow hedge. If we

have any that meet this criteria, changes in the fair value of these cash flow hedges that are highly effective are recorded in accumulated other
comprehensive income and reclassified into earnings in the same line item on the consolidated statements of operations as the impact of the hedged
transaction during the period in which the hedged transaction affects earnings. The ineffective portion of cash flow hedges are recognized immediately in
other income and expenses. Derivatives that we designate as cash flow hedges are classified in the consolidated statements of cash flows in the same section
as the underlying item, primarily within cash flows from operating activities. The changes in fair value of derivative instruments that are not designated as
hedges are recognized immediately in other income (expense).

We formally document all relationships between hedging instruments and hedged items, as well as the risk management objective and strategy for

undertaking various hedge transactions. This process includes linking all derivatives that are designated as cash-flow hedges to specific forecasted
transactions. We also assess, both at the hedge's inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly
effective in offsetting changes in cash flows of the hedged items.

Accounts Receivable Allowances

Accounts receivable allowances reflect our best estimate of probable losses inherent in our accounts receivable balances, including both losses for

uncollectible accounts receivable and sales returns. We regularly review allowances by considering factors such as historical experience, credit quality, the
age of the accounts receivable balances, and current economic conditions that may affect a customer's ability to pay.

Asset Retirement Obligations

The fair value (the present value of estimated cash flows) of a liability for an asset retirement obligation is recognized in the period in which it is

incurred if a reasonable estimate of fair value can be made. The fair value of the liability is added to the carrying amount of the associated asset and this
additional carrying amount is depreciated over the life of the asset. All of our existing asset retirement obligations are associated with commitments to return
the property to its original condition upon lease termination at various sites and costs to clean up and dispose of certain fixed assets at our Sunnyvale,
California site. We estimated that as of fiscal 2021 year-end, gross expected future cash flows of $6.8 million would be required to fulfill these obligations.

At October 2, 2021, $0.4 million and $6.0 million of the asset retirement liability were included in Other current liabilities and Other long-term
liabilities, respectively, on our consolidated balance sheets. At October 3, 2020, $0.3 million and $5.9 million of the asset retirement liability were included
in Other current liabilities and Other long-term liabilities, respectively, on our consolidated balance sheets.

Long-lived Assets

We evaluate the carrying value of long-lived assets, including intangible assets, whenever events or changes in business circumstances or our planned

use of long-lived assets indicate that their carrying amounts may not be fully recoverable or that their useful lives are no longer appropriate. Reviews are
performed to determine whether the carrying values of long-lived assets are impaired based on a comparison to the undiscounted expected future net cash
flows. If the comparison indicates that impairment exists, long-lived assets that are classified as held and used are written down to their respective fair
values. When long-lived assets are classified as held for sale, they are written down to their respective fair values less costs to sell. Significant management
judgment is required in the forecast of future operating results that is used in the preparation of expected undiscounted cash flows. For fiscal 2020, we
recorded non-cash pre-tax charges in the quarter ended April 4, 2020 related to the intangible assets, property, plant and equipment, and right-of-use
("ROU") assets of the ILS reporting unit of $33.9 million, $85.6 million, and $1.8 million, respectively (See Note 8, "Goodwill and Intangible Assets").

Goodwill

Goodwill is tested for impairment on an annual basis and between annual tests in certain circumstances, and written down when impaired (See Note 8,
"Goodwill and Intangible Assets"). In testing for impairment, we have the option to first assess qualitative factors to determine whether it is more likely than
not (that is, a likelihood of more than 50%) that the fair value of a reporting unit is less than its carrying amount. Moreover, an entity can bypass the
qualitative assessment for any reporting unit in any period and proceed directly to the impairment test, and then resume performing the qualitative
assessment in any subsequent period. In our fiscal 2021 annual testing, for our OLS reporting unit we conducted a qualitative assessment of the goodwill
during the fourth quarter using the opening balance sheet as of the first day of the fourth quarter and concluded that it was more likely than not that the fair
value of the reporting unit exceeded its carrying amounts. Based on our assessment, goodwill in the OLS reporting unit was not impaired as of the first day
of the fourth quarter of fiscal 2021. As such, it was not necessary to perform the goodwill impairment test in the fourth quarter of fiscal 2021. There is no
goodwill in the ILS reporting unit due to the impairment of all goodwill of the ILS reporting unit in the second quarter of fiscal 2020.

Intangible Assets

Intangible assets, including acquired existing technology, customer relationships and production know-how are amortized on a straight-line basis over

their estimated useful lives, currently 4 years to 15 years (See Note 8, "Goodwill and Intangible Assets").

Warranty Reserves

We provide warranties on the majority of our product sales and reserves for estimated warranty costs are recorded during the period of sale. The
determination of such reserves requires us to make estimates of product return rates and expected costs to repair or replace the products under warranty. We
currently establish warranty reserves based on historical warranty costs for each product line. The weighted average warranty period covered is
approximately 15 months to 18 months. If actual return rates and/or repair and replacement costs differ significantly from our estimates, adjustments to cost
of sales may be required in future periods.

Components of the reserve for warranty costs during fiscal 2021, 2020, and 2019 were as follows (in thousands):

We are subject to the possibility of various loss contingencies arising in the ordinary course of business. We consider the likelihood of loss or

impairment of an asset, or the incurrence of a liability, as well as our ability to reasonably estimate the amount of loss, in determining loss contingencies. An
estimated loss contingency is accrued when it is probable that an asset has been impaired or a liability has been incurred and the amount of loss can be
reasonably estimated. If we determine that a loss is possible and the range of the loss can be reasonably determined, then we disclose the range of the
possible loss. We regularly evaluate current information available to us to determine whether an accrual is required, an accrual should be adjusted or a range
of possible loss should be disclosed.

Revenue Recognition

Effective September 30, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers ("ASC 606"), using the modified retrospective

transition method applied to contracts that were not completed as of September 29, 2018. Under ASC 606, we determine revenue recognition by applying
the following five-step approach:

Identification of the contract, or contracts, with a customer;
Identification of the performance obligations in the contract;

Step 1
Step 2
Step 3 Determination of the transaction price;
Step 4 Allocation of the transaction price to the performance obligations in the contract; and
Step 5 Recognition of revenue when, or as, we satisfy each performance obligation.

Contracts and customer purchase orders, which in some cases are governed by master sales agreements, are generally used to determine the existence
of an arrangement. In addition, shipping documents and customer acceptance, if applicable, are used to verify delivery and transfer of control. Performance
obligations are identified based on the products or services that will be transferred to the customer that are considered distinct. Being distinct is defined as
products or services that the customer can benefit from either on its own or together with other resources that are readily available from third parties or from
us, and by the product or service being separately identifiable from other promises in the contract. We assess our ability to collect from our customers based
primarily on the creditworthiness and past payment history of each customer. Revenue from all sales are recognized at the transaction price. The transaction
price is determined based on the consideration to which we will be entitled in exchange for transferring goods or services to the customer adjusted for
estimated variable consideration, if any. The consideration associated with customer contracts is generally fixed. Variable consideration includes discounts,
rebates, credits and incentives, or other similar items. The amount of consideration that can vary is not a substantial portion of the total consideration.
Variable consideration estimates are re-assessed at each reporting period until a final outcome is determined.

78

 
 
Table of Contents

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

Changes to the original transaction price due to a change in estimated variable consideration are calculated on a retrospective basis, with the adjustment
recorded in the period in which the change occurs.

Sales to customers are generally not subject to any price protection or return rights. Accordingly, upon application of steps one through five above,
product revenue is recognized upon shipment and transfer of control. The majority of products and services offered by us have readily observable selling
prices. As a part of our stand-alone selling price policy, we review product pricing on a periodic basis to identify any significant changes and revise our
expected selling price assumptions as appropriate.

We record taxes collected on revenue-producing activities on a net basis.

Revenue recognition at a point in time

Revenues recognized at a point in time consist primarily of product, installation and training. The majority of our sales are made to original equipment
manufacturers ("OEMs"), distributors, representatives and end-users. Sales made to customers generally do not require installation of the products by us and
are not subject to other post-delivery obligations. Sales to end-users in the scientific market typically require installation by us and, thus, involve post-
delivery obligations; however, our post-delivery installation obligations are not essential to the functionality of our products and represent a separate
performance obligation. We recognize revenue for these sales following the transfer of control of such products to the customer, which typically occurs upon
shipment or delivery depending on the terms of the underlying contracts. In those instances that we have agreed to perform installation or provide training,
we defer revenue related to installation or training until these services have been rendered.

Our sales to distributors, representatives and end-user customers typically do not have customer acceptance provisions and only certain of our sales to
OEM customers and integrators have customer acceptance provisions. Customer acceptance is generally limited to performance under our published product
specifications. For the few product sales that have customer acceptance provisions because of more advanced performance than our published specifications,
the revenue is recognized when the control transfers or the revenue is deferred until customer acceptance occurs.

Revenue recognition over time

We periodically enter into contracts in which a customer may purchase a combination of goods and/or services, such as products with maintenance

contracts or extended warranty. These contracts are evaluated to determine if the multiple promises are separate performance obligations. Once we
determine the performance obligations, we then determine the transaction price, which includes estimating the amount of variable consideration, if any. We
then allocate the transaction price to each performance obligation in the contract based on a relative stand-alone selling price charged separately to
customers. Extended warranties are sold separately from products and represent a distinct performance obligation. Revenue related to the performance
obligation for extended warranties is recognized over time as the customer simultaneously receives and consumes the benefits provided by us.

Customized products, for which we have an enforceable right to payment for performance completed to date, are recorded over time. We use the output

method to recognize revenue over time for such contracts as it best depicts the satisfaction of our performance obligations.

Shipping and handling costs

We record costs related to shipping and handling of net sales in cost of sales for all periods presented. Shipping and handling fees billed to customers

are included in net sales. Customs duties billed to customers are recorded in cost of sales.

79

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

Warranty

We provide warranties on the majority of our product sales and reserves for estimated warranty costs are recorded during the period of sale. These

standard warranties are assurance type warranties and do not offer any services beyond the assurance that the product will continue working as specified.
Therefore, these warranties are not considered separate performance obligations in the arrangement. Instead, the expected cost of the warranty is accrued as
an expense. The determination of such reserves requires us to make estimates of product return rates and expected costs to repair or replace the products
under warranty. We currently establish warranty reserves based on historical warranty costs for each product line. The weighted average warranty period
covered is approximately 15 to 18 months. If actual return rates and/or repair and replacement costs differ significantly from our estimates, adjustments to
cost of sales may be required in future periods.

Costs of obtaining a contract

We recognize the incremental direct costs of obtaining a contract from a customer as an expense, which primarily includes sales commissions. Sales

commissions are recorded at a point of time when control of the product transfers or over a period of time when sales commission provided is expected to be
recovered through future services. The costs are recorded within selling, general and administrative expense. Costs incurred prior to the transfer of control of
the product to the customer and costs to be amortized over a future period are classified as a prepaid asset and are included in prepaid expenses and other
assets. Upon adoption of ASC 606, we determined there was an immaterial impact on sales commissions and therefore, we did not record a transition
adjustment on adoption. For fiscal 2021 and 2020, costs of obtaining a contract to be amortized over a future period of $0.2 million and $0.3 million were
classified as a prepaid asset and are included in prepaid expenses and other assets, respectively.

Payment terms

Our standard payment terms are 30 days but vary by the industry and location of the customer and the products or services offered. The time between
invoicing and when payment is due is not significant. As our standard payment terms are less than one year, we have elected the practical expedient under
ASC 606-10-32-18 and therefore are not required to assess whether each contract has a significant financing component.

Customer deposits and deferred revenue

When we receive consideration from a customer prior to transferring goods or services under the terms of a sales contract, we record customer deposits

or deferred revenue, depending on whether or not the product has shipped to the customer, which are included in other current liabilities or other long-term
liabilities when the payment is made or due, whichever is earlier. We recognize deferred revenue as net sales after control of the goods or services has been
transferred to the customer and all revenue recognition criteria are met.

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 and engineering
services are included in research and development expenses as incurred as they do not directly relate to any particular licensee, license agreement or license
fee.

We treat third party and government funding of our research and development activity, where we are the primary beneficiary of such work conducted,

as a reduction of research and development cost. Research and development reimbursements of $2.1 million, $3.4 million, and $3.8 million were offset
against research and development costs in fiscal 2021, 2020, and 2019, respectively.

Foreign Currency Translation

The functional currencies of our foreign subsidiaries are generally their respective local currencies. Accordingly, gains and losses from the translation

of the financial statements of the foreign subsidiaries are reported as a separate component of accumulated other comprehensive income ("OCI"). Foreign
currency transaction gains and losses are included in earnings.

Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions and other events and
circumstances from non-owner sources. Accumulated other comprehensive income (loss) (net of tax) at fiscal 2021 year-end was substantially comprised of
accumulated translation adjustments of $20.4 million and deferred actuarial losses on pension plans of $0.4 million. Accumulated other comprehensive loss
(net of tax) at fiscal 2020 year-end was substantially comprised of accumulated translation adjustments of $25.1 million and deferred actuarial losses on
pension plans of $0.5 million.

Earnings Per Share

Basic earnings per share is computed based on the weighted average number of shares outstanding during the period, excluding unvested restricted

stock. Diluted earnings per share is computed based on the weighted average number of shares outstanding during the period increased by the effect of
dilutive employee stock awards, including restricted stock awards and stock purchase plan contracts, using the treasury stock method.

98,103 potentially dilutive securities excluded from the dilutive share calculation for fiscal 2019 as their effect was anti-dilutive.

Stock-Based Compensation

We recognize compensation expense for all share-based payment awards based on the fair value of such awards. We value restricted stock units using
the intrinsic value method, which is based on the fair market value price on the grant date. We use a Monte Carlo simulation model to estimate the fair value
of performance restricted stock units whose number of units vesting is based on our total shareholder return over the performance period compared to the
Russell Index. In fiscal 2020, we valued certain performance restricted stock units with vesting based on goals related to free cash flow target amounts units
using the intrinsic value method, which is based on the fair market value price on the grant date. We amortize the fair value of stock awards on a straight-line
basis over the requisite service periods of the awards, which are generally the vesting periods. See Note 12, "Employee Stock Award and Benefit Plans" for a
description of our stock-based employee compensation plans and the assumptions we use to calculate the fair value of stock-based employee compensation.

Income Taxes

As part of the process of preparing our consolidated financial statements, we are required to estimate our income tax provision (benefit) in each of the

jurisdictions in which we operate. This process involves us estimating our current income tax provision (benefit) together with assessing temporary
differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which
are included within our consolidated balance sheets.

We account for uncertain tax issues pursuant to ASC 740-10 Income Taxes, which creates a single model to address accounting for uncertainty in tax
positions by prescribing a minimum recognition threshold that a tax position is required to meet before being recognized in the financial statements. This
standard provides a two-step approach for evaluating tax positions. The first step, recognition, occurs when a company concludes (based solely on the
technical aspects of the matter) that a tax position is more likely than not to be sustained upon examination by a taxing authority. The second step,

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

measurement, is only considered after step one has been satisfied and measures any tax benefit at the largest amount that is deemed more likely than not to
be realized upon ultimate settlement of the uncertainty. These determinations involve significant judgment by management. Tax positions that fail to qualify
for initial recognition are recognized in the first subsequent interim period that they meet the more likely than not standard or when they are resolved
through negotiation or litigation with factual interpretation, judgment and certainty. Tax laws and regulations themselves are complex and are subject to
change as a result of changes in fiscal policy, changes in legislation, evolution of regulations and court filings. Therefore, the actual liability for U.S. or
foreign taxes may be materially different from our estimates, which could result in the need to record additional tax liabilities or potentially to reverse
previously recorded tax liabilities.

We record a valuation allowance to reduce our deferred tax assets to an amount that more likely than not will be realized. While we have considered
future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance, in the event we were to
determine that we would be able to realize our deferred tax assets in the future in excess of our net recorded amount, an adjustment to the allowance for the
deferred tax asset would increase income in the period such determination was made. Likewise, should we determine that we would not be able to realize all
or part of our net deferred tax asset in the future, an adjustment to the allowance for the deferred tax asset would be charged to income in the period such
determination was made.

We historically asserted our intention to indefinitely reinvest foreign earnings. As a result of enactment of the Tax Cuts and Jobs Act (the “Tax Act”)

and certain foreign tax law changes, we no longer consider foreign earnings to be indefinitely reinvested in our foreign subsidiaries. As a result of this
change in assertion, we recorded a $18.4 million tax expense against our foreign earnings that are not indefinitely reinvested as of fiscal 2021. This is mainly
related to foreign withholding taxes and state income taxes. We have not recognized any deferred taxes for outside basis differences in foreign subsidiaries.

Adoption of New Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, Financial Instruments -
Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and a subsequent amendment, ASU 2018-19 (collectively, "Topic 326").
Topic 326 requires measurement and recognition of expected credit losses for financial assets held. We adopted ASU 2016-13 in the first quarter of fiscal
2021 with no material impact to our consolidated financial statements.

With the adoption of Topic 326, we are now assessing whether unrealized losses have resulted from or are expected to result from a credit loss or other

factors. We believe none of our unrealized losses on available-for-sale investments were other-than temporary or were attributable to credit losses as of
October 2, 2021 and October 3, 2020. We review our available-for-sale investments on a quarterly basis to identify a potential other-than-temporary
impairment. We also do not have an intent to sell our investments and would not be required to sell them before they recover.

The adoption of Topic 326 did not significantly change our approach to the valuation of trade receivables. We determine whether there is an expected
loss on our accounts receivable by reviewing all available data, including our customers' latest available financial statements, their credit standing and our
historical collection experience, as well as current and future market and economic conditions. As of October 2, 2021 and October 3, 2020, the allowance for
credit losses on our trade receivables was $4.4 million and $5.4 million, respectively.

Recently Issued Accounting Pronouncements

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform ("Topic 848"). Topic 848 provides optional expedients and exceptions for

applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by the discontinuation of the London Interbank Offered Rate
("LIBOR") or by another reference rate expected to be discontinued. The guidance was effective beginning March 12, 2020 and can be applied prospectively
through December 31, 2022. In January 2021, the FASB issued ASU 2021-01, "Reference Rate Reform - Scope," which clarified the scope and application
of the original guidance. We will adopt these standards when LIBOR is discontinued and do not expect them to have a material impact on our consolidated
financial statements or related disclosures.

Contract Balances

We record accounts receivable when we have an unconditional right to the consideration. Contract liabilities are recorded when cash payments are

received or due in advance of performance. Contract liabilities consist of customer deposits and deferred revenue, where we have unsatisfied or partly
satisfied performance obligations. Contract liabilities classified as customer deposits are included in other current liabilities and contract liabilities classified
as deferred revenue are included in other current liabilities or other long-term liabilities on our consolidated balance sheets. Payment terms vary by
customer.

4. BUSINESS COMBINATIONS

Merger Agreement

On January 18, 2021, we entered into an Agreement and Plan of Merger with Lumentum Holdings Inc. ("Lumentum"), Cheetah Acquisition Sub, Inc.

("Lumentum Merger Sub I") and Cheetah Acquisition Sub LLC ("Lumentum Merger Sub II") (the "Original Lumentum Merger Agreement"), pursuant to
which we agreed to be acquired for $100.00 in cash per Coherent share and 1.1851 shares of Lumentum common stock per Coherent share. In light of
unsolicited proposals received from each of MKS Instruments, Inc. and II-VI Incorporated ("II-VI"), on March 9, 2021, we entered into an Amended and
Restated Agreement and Plan of Merger with Lumentum, Lumentum Merger Sub I and Lumentum Merger Sub II (the "Amended Lumentum Agreement"),
pursuant to which we agreed to be acquired for $175.00 in cash per Coherent share and 1.0109 shares of Lumentum common stock per Coherent share.

On March 25, 2021, we terminated the Amended Lumentum Agreement and entered into an Agreement and Plan of Merger with II-VI and Watson

Merger Sub Inc. ("II-VI Merger Sub") (the "II-VI Merger Agreement"), pursuant to which we agreed to be acquired for $220.00 in cash per Coherent share
and 0.91 of a share of II-VI common stock per Coherent share. In connection with terminating the Amended Lumentum Agreement, we paid a termination
fee of $217.6 million to Lumentum during our second quarter of fiscal 2021. The termination fee, in addition to other costs related to the merger agreements
with Lumentum and II-VI, is included in merger and acquisition costs in our consolidated statements of operations.

Pursuant to the terms of the II-VI Merger Agreement, the acquisition of Coherent will be accomplished through a merger of II-VI Merger Sub with and

into Coherent (the "Merger"), with Coherent surviving the Merger as a wholly owned subsidiary of II-VI.

Pursuant to the terms of the II-VI Merger Agreement, and subject to the terms and conditions set forth therein, at the effective time of the Merger (the
"Effective Time"), each share of the common stock of Coherent (the "Coherent Common Stock") issued and outstanding immediately prior to the Effective
Time (other than (x) shares of Coherent Common Stock owned by II-VI, Coherent, or any direct or indirect wholly owned subsidiary of II-VI or Coherent or
(y) shares of Coherent Common Stock owned by stockholders who have properly exercised and perfected appraisal rights under Delaware law, in each case,
immediately prior to the Effective Time), will be cancelled and extinguished and automatically converted into the right to receive the following
consideration:

(A) $220.00 in cash, without interest, plus

4. BUSINESS COMBINATIONS (Continued)

(B) 0.91 of a validly issued, fully paid and non-assessable share of the common stock of II-VI.

The completion of Coherent's acquisition by II-VI is subject to customary closing conditions, including, among others, regulatory approvals in

applicable jurisdictions including the United States, Germany, China and South Korea.

Electro-Optics Technology

On April 19, 2021, we acquired EOT for approximately $29.3 million, excluding transaction costs. EOT is a specialized U.S.-based components

company, which we expect will enable us to vertically integrate and improve the performance of our directed energy amplifier technology. EOT has
additional operations through a subsidiary in Germany. EOT's operating results have been included in our OEM Laser Sources segment. See Note 18,
"Segment and Geographic Information."

been presented separately because the effect of the acquisition was not material to our consolidated financial results. Pro forma results of operations in
accordance with authoritative guidance for prior periods have not been presented because the effect of the acquisition was not material to our prior period
consolidated financial results.

The identifiable intangible assets are being amortized over their respective useful lives of 1 to 5 years. The fair value of the acquired intangibles was
determined using the income approach. In performing these valuations, the key underlying probability-adjusted assumptions of the discounted cash flows
were projected revenues, gross margin expectations and operating cost estimates. The valuations were based on the information that was available as of the
acquisition date and the expectations and assumptions that have been deemed reasonable by our management. There are inherent uncertainties and
management judgment required in these determinations. This acquisition resulted in a purchase price that exceeded the estimated fair value of tangible and
intangible assets, which was allocated to goodwill.

We believe the amount of goodwill relates to several factors including: (1) potential buyer-specific synergies in connection with the development of

new technologies primarily for the defense business; and (2) the potential to leverage our sales force to attract new customers and revenue and cross-sell to
existing customers.

None of the goodwill from this purchase is deductible for tax purposes.

Results of operations for the business have been included in our consolidated financial statements subsequent to the date of acquisition and pro forma

results of operations in accordance with authoritative guidance for prior periods have not been presented because the effect of the acquisition was not

The identifiable intangible assets are being amortized over their respective useful lives of 1 to 8 years. The fair values of the acquired intangibles were

determined using the income approach. In performing these valuations, the key underlying probability-adjusted assumptions of the discounted cash flows
were projected revenues, gross margin expectations and operating cost estimates. The valuations were based on the information that was available as of the

management judgment required in these determinations. This acquisition resulted in a purchase price that exceeded the estimated fair value of tangible and

We believe the amount of goodwill relative to identifiable intangible assets relates to several factors including: (1) potential buyer-specific synergies

related to the development of new technologies; and (2) the potential to leverage our sales force to attract new customers.

In the quarter ended April 4, 2020, we performed an interim impairment test and the entire goodwill balance and a portion of the existing technology

intangible assets were impaired. See Note 8, "Goodwill and Intangible Assets".

None of the goodwill from this purchase is deductible for tax purposes.

management judgment required in these determinations.

5. FAIR VALUES

We measure our cash equivalents and marketable securities at fair value. The fair values of our financial assets and liabilities are determined using
quoted market prices of identical assets or quoted market prices of similar assets from active markets. We recognize transfers between levels within the fair
value hierarchy, if any, at the end of each quarter. There were no transfers between levels during the periods presented. As of October 2, 2021 and October 3,
2020, we had one investment carried on a cost basis. See Note 9, "Balance Sheet Details." If we were to fair value this investment, it would be based upon
Level 3 inputs. This investment is not considered material to our consolidated financial statements.

We measure the fair value of outstanding debt obligations for disclosure purposes on a recurring basis. As of October 2, 2021, the current and long-
term portion of long-term obligations of $8.4 million and $425.8 million, respectively, are reported at amortized cost. As of October 3, 2020, the current and
long-term portion of long-term obligations of $6.8 million and $411.1 million, respectively, are reported at amortized cost. These outstanding obligations are
classified as Level 2 as they are not actively traded and are valued using a discounted cash flow model that uses observable market inputs. Based on the
discounted cash flow model, the fair value of the outstanding debt approximates amortized cost.

 ___________________________________________________

(1)     Valuations are based upon quoted market prices in active markets involving similar assets. The market inputs used to value these instruments generally consist of

market yields, reported trades, broker/dealer quotes or alternative pricing sources with reasonable levels of price transparency. Pricing sources include industry standard
data providers, security master files from large financial institutions, and other third party sources which are input into a distribution-curve-based algorithm to
determine a daily market value. This creates a "consensus price" or a weighted average price for each security.

(2)    The principal market in which we execute our foreign currency contracts is the institutional market in an over-the-counter environment with a relatively high level of

price transparency. The market participants usually are large commercial banks. Our foreign currency contracts' valuation inputs are based on quoted prices and quoted
pricing intervals from public data sources and do not involve management judgment. See Note 7, "Derivative Instruments and Hedging Activities."

(3)    The fair value of mutual funds is determined based on quoted market prices. Securities traded on a national exchange are stated at the last reported sales price on the day

of valuation; other securities traded in over-the-counter markets and listed securities for which no sale was reported on that date are stated as the last quoted bid price.

6. SHORT-TERM INVESTMENTS

We consider all highly liquid investments with maturities of three months or less at the time of purchase to be cash equivalents. Investments classified

as available-for-sale are reported at fair value with unrealized gains and losses, net of related income taxes, recorded as a separate component of OCI in
stockholders' equity until realized. Interest and amortization of premiums and discounts for debt securities are included in interest income. Gains and losses
on securities sold are determined based on the specific identification method and are included in other income (expense).

There were no unrealized gains and losses at October 2, 2021. There were less than $0.1 million of unrealized gains and losses at October 3, 2020.

During fiscal 2021, there were no proceeds from the sale of available-for-sale securities and we realized no gross gains or losses. During fiscal 2020,

we received $5,000 in proceeds from the sale of available-for-sale securities and realized no gross gains or losses.

7. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

We maintain operations in various countries outside of the United States and have foreign subsidiaries that manufacture and sell our products in
various global markets. The majority of our sales are transacted in U.S. Dollars. However, we do generate revenues in other currencies, primarily the Euro,
Chinese Renminbi, South Korean Won, Japanese Yen, and British Pound. As a result, our earnings, cash flows, and cash balances are exposed to fluctuations
in foreign currency exchange rates. We attempt to limit these exposures through financial market instruments. We utilize derivative instruments, primarily
forward contracts with maturities of two months or less, to manage our exposure associated with anticipated cash flows and net asset and liability positions
denominated in foreign currencies. Gains and losses on the forward contracts are mitigated by gains and losses on the underlying instruments. We do not use
derivative financial instruments for speculative or trading purposes. The credit risk amounts represent our gross exposure to potential accounting loss on
derivative instruments that are outstanding or unsettled if all counterparties failed to perform according to the terms of the contract, based on then-current
currency rates at each respective date.

The fair value of our derivative instruments is included in prepaid expenses and other assets and in other current liabilities in our Consolidated Balance

Sheets. See Note 5, "Fair Values."

During fiscal 2021, 2020, and 2019, we recognized a loss of $5.1 million, a gain of $1.1 million, and a loss of $5.8 million, respectively, in other

income (expense) for derivative instruments not designated as hedging instruments.

Master Netting Arrangements

To mitigate credit risk in derivative transactions, we enter into master netting arrangements that allow each counterparty in the arrangements to net

settle amounts of multiple and separate derivative transactions under certain conditions. We present the fair value of derivative assets and liabilities within
our consolidated balance sheet on a gross basis even when derivative transactions are subject to master netting arrangements and may otherwise qualify for
net presentation. The impact of netting derivative assets and liabilities is not material to our financial position for any of the periods presented. Our
derivative contracts do not contain any credit risk related contingent features and do not require collateral or other security to be furnished by us or the
counterparties.

8. GOODWILL AND INTANGIBLE ASSETS

Goodwill is tested for impairment on an annual basis and between annual tests if events or circumstances indicate that an impairment loss may have
occurred, and we write down these assets when impaired. We perform our annual impairment tests during the fourth quarter of each fiscal year using the
opening balance sheet as of the first day of the fourth quarter, with any resulting impairment recorded in the fourth quarter of the fiscal year.

In the quarter ended April 4, 2020, the worldwide spread of coronavirus ("COVID-19") created significant volatility, uncertainty and disruption to the

global economy, representing an indicator to test our goodwill for impairment. Based on our internal projections and the preparation of our financial
statements for the quarter ended April 4, 2020, and considering the forecasted decrease in demand due to the COVID-19 pandemic and other factors, we
believed that the fair value of our ILS reporting unit might no longer have exceeded its carrying value and performed an interim goodwill impairment test on
the ILS reporting unit. We also performed an interim goodwill impairment test on the OLS reporting unit.

Our goodwill impairment tests for the ILS and OLS reporting units were performed by comparing the fair value of the reporting units with their
carrying values and recognizing an impairment charge for the amount by which the carrying value exceeded the fair value. Based on the estimated fair value
of the ILS reporting unit, in the quarter ended April 4, 2020, we recorded a non-cash pre-tax charge related to the ILS reporting unit of $327.2 million,
reducing the goodwill balance of the reporting unit to zero. The impairment charge was primarily the result of a decline in projected cash flows of the ILS
reporting unit driven by lower forecasted sales volumes and profitability in several business units. The impairment charge was also the result of changes in
certain market-related inputs to the analysis to reflect macro-economic changes caused by the impact of COVID-19, including lower pricing multiples for
comparable public companies. No impairment charge was recognized for the OLS reporting unit as the fair value significantly exceeded the carrying value
of the reporting unit.

In assessing goodwill for impairment, we were required to make significant judgments related to the fair value of our reporting units. We used a
combination of the Income (discounted cash flow) approach and the Market (market comparable) approach to estimate the fair value of our reporting units.
The Income approach utilizes the discounted cash flow model to provide an estimation of fair value based on the cash flows that a business expects to
generate. These cash flows are based on

forecasts developed internally by management which are then discounted at an after tax rate of return required by equity and debt market participants of a
business enterprise. Our assumptions used in the forecasts are based on historical data, supplemented by current and anticipated market conditions, estimated
growth rates, and management’s plans. The rate of return on cost of capital is weighted based on the capitalization of comparable companies. We utilized a
discount rate for each of our reporting units that represents the risks that our businesses face, considering their sizes, their current economic environment and
other industry data as we believe is appropriate. The Market approach determines fair value by comparing the reporting units to comparable companies in
similar lines of business that are publicly traded. The selection of comparable companies is based on the markets in which the reporting units operate giving
consideration to risk profiles, size, geography and diversity of products and services. Total Enterprise Value (TEV) multiples such as TEV to revenues and
TEV to earnings (if applicable) before interest and taxes of the publicly traded companies are calculated. We utilized multiples for each of our reporting
units that represent the risks that our businesses face, considering their sizes, their current economic environment and other industry data as we believe is
appropriate. The interim goodwill impairment testing results were also reconciled with our market capitalization as of April 4, 2020, as the final step in the
impairment testing.

Before performing the goodwill impairment test for the ILS reporting unit, we performed impairment tests on the long-lived assets allocated to the
asset group of the ILS reporting unit, including intangible assets, property, plant and equipment, and ROU assets as of April 4, 2020, due primarily to the
same indicators that led to the interim goodwill impairment testing. Based on the impairment tests performed, we concluded that some of the long-lived
assets allocated to the asset group of the ILS reporting unit were impaired as of April 4, 2020. Accordingly, we recorded non-cash pre-tax charges in the
quarter ended April 4, 2020 related to the intangible assets, property, plant and equipment, and right-of-use ("ROU") assets of the ILS reporting unit of $33.9
million, $85.6 million, and $1.8 million, respectively. We did not identify any indicators that would lead us to believe that the carrying value of the long-
lived assets allocated to the asset group of the OLS reporting unit may not be recoverable as of April 4, 2020.

We evaluate long-lived assets and amortizable intangible assets whenever events or changes in business circumstances or our planned use of assets
indicate that their carrying amounts may not be fully recoverable or that their useful lives are no longer appropriate. In assessing our long-lived assets for
impairment, we were required to make significant judgments related to the fair value of our long-lived assets, which are comprised of personal property, real
property, and intangible assets. We used a combination of the Income, the Market approach, and the Cost (cost to create) approach to estimate the fair value
of our long-lived assets. Our personal property assets consist of laser manufacturing and assembly equipment, semiconductor tools, laboratory and test
equipment, furniture and fixtures, and computer hardware and software. We used the Cost Approach (with support from the Market Approach) to estimate
the fair value of our personal property, taking into consideration the physical deterioration, functional obsolescence, and economic obsolescence of our
personal property assets. Our real property assets consist of land and buildings, land rights (ground leased), and ROU assets. In determining the fair value of
our real property assets, we used a combination of the Income, Market (sales comparison), and Cost approaches. We considered historical transaction
information, current market conditions, operating performance, forecast growth, and market-derived rates of return in our real property determination of fair
value. The fair value of our ROU assets was determined using the Income approach by considering off-market components of the associated ROU leases.
Our intangible assets consist of technology and customer relationship assets, and we used the Income approach to estimate the fair value of our intangible
assets. We identified cash flows associated with each intangible asset, which were discounted at an after-tax rate of return appropriate for the risk profile of
each intangible asset.

We performed our annual impairment test using the opening balance sheet as of the first day of the fourth quarter of fiscal 2020 and noted no
indications of impairment or triggering events, not already considered in the quarter ended April 4, 2020. During the remainder of fiscal 2020 and the first
three quarters of fiscal 2021, we noted no indications of impairment or triggering events to cause us to review goodwill for potential impairment. We
performed our annual impairment test using the opening balance sheet as of the first day of the fourth quarter of fiscal 2021 and noted no indications of
impairment or triggering events. In our fiscal 2021 annual testing, for our OLS reporting unit we conducted a qualitative assessment of the goodwill during
the fourth quarter using the opening balance sheet as of the first day of the fourth quarter and concluded that it was more likely than not that the fair value of
the reporting unit exceeded its carrying amounts. Based on our assessment, goodwill in the OLS reporting unit was not impaired as of the first day of the
fourth quarter of fiscal 2021. As such, it was not necessary to perform the goodwill impairment test in the fourth quarter of fiscal 2021. There is no goodwill
in the ILS reporting unit due to the impairment of all goodwill of the ILS reporting unit in the second quarter of fiscal 2020. Between the completion of our
assessment and the end of the fourth quarter of fiscal 2021, we noted no indications of impairment or triggering events to cause us to review goodwill for
potential impairment.

On December 21, 2020, Coherent LaserSystems GmbH & Co. KG entered into a loan agreement with Commerzbank for borrowings of up to 24.0
million Euros, to be drawn down by October 29, 2021, to finance a portion of the construction of a new facility in Germany. The term of the loan is 10 years
and borrowings bear interest at 1.55% per annum. Payments will be payable quarterly beginning in the third quarter of fiscal 2022. As of October 2, 2021,
24.0 million Euros have been withdrawn under this loan facility. The loan agreement contains customary affirmative loan covenants. We were in compliance
with all covenants at October 2, 2021.

On November 7, 2016 (the "Closing Date"), we entered into a Credit Agreement by and among us, Coherent Holding BV & Co. K.G. (formerly
Coherent Holding GmbH), as borrower (the "Borrower"), and certain of our direct and indirect subsidiaries from time to time party thereto, as guarantors,
the lenders from time to time party thereto, Barclays Bank PLC, as administrative agent and an L/C Issuer, Bank of America, N.A., as an L/C Issuer, and
MUFG Union Bank, N.A., as an L/C Issuer (the "Initial Credit Agreement" and, as amended by the Amendments (defined below), the "Credit Agreement").
The Initial Credit Agreement provided for a 670.0 million Euro senior secured term loan facility (the "Euro Term Loan") and a $100.0 million senior secured
revolving credit facility (the "Revolving Credit Facility") with a $30.0 million letter of credit sublimit and a $10.0 million swing line sublimit, in each case,
which may be increased from time to time pursuant to an incremental feature set forth in the Credit Agreement. The Initial Credit Agreement was amended
on May 8, 2017 (the "First Amendment") to reduce the interest rate margins applicable to the Euro Term Loan and was amended again on July 5, 2017 (the
"Second Amendment" and, together with the First Amendment, the "Amendments") to make certain technical changes in connection with the conversion of
the Borrower from a German company with limited liability to a German limited partnership.

The Credit Agreement contains customary mandatory prepayment provisions. The Borrower has the right to prepay loans under the Credit Agreement
in whole or in part at any time without premium or penalty, subject to customary breakage costs. Revolving loans may be borrowed, repaid and reborrowed
until the fifth anniversary of the Closing Date, at which time all outstanding revolving loans must be repaid. The Euro Term Loan matures on the seventh
anniversary of the Closing Date (in the first quarter of fiscal 2024), at which time all outstanding principal and accrued and unpaid interest on the Euro Term
Loan must be repaid.

As of October 2, 2021, the outstanding principal amount of the Euro Term Loan was 351.5 million Euros. As of October 2, 2021, the outstanding

amount of the Revolving Credit Facility was $10.0 million plus a 10.0 million Euro letter of credit.

On October 29, 2021, we entered into a 10.0 million Euro letter of credit facility, rolled our existing letter of credit into that facility and deposited 10.5

million Euros with Barclays as cash collateral to secure the payment obligations under such facility, resulting in restricted cash of $12.2 million.

On October 29, 2021, we repaid the $10.0 million outstanding under the Revolving Credit Facility and the facility expired on November 5, 2021.

Loans under the Credit Agreement bear interest, at the Borrower's option, at a rate equal to either (i)(x) in the case of calculations with respect to U.S.

Dollars or certain other alternative currencies, the London interbank offered rate ("LIBOR") or (y) in the case of calculations with respect to the Euro, the
euro interbank offered rate ("EURIBOR" and, together with LIBOR), (the "Eurocurrency Rate") or (ii) a base rate (the "Base Rate") equal to the highest of
(x) the federal funds rate, plus 0.50%, (y) the prime rate then in effect and (z) the Eurocurrency Rate for loans denominated in U.S. Dollars applicable to a
one-month interest period, plus 1.0%, in each case, plus an applicable margin that is subject to adjustment pursuant to a pricing grid based on consolidated
total gross leverage ratio. At October 2, 2021, the applicable margin for Euro Term Loans borrowed as Eurocurrency Rate loans was 2.25% per annum and
as Base Rate loans was 1.25%. The applicable margin for revolving loans borrowed as Eurocurrency Rate loans was 4.00% per annum and as Base Rate
loans was 3.00% per annum. Interest on Base Rate Loans is payable quarterly in arrears. Interest on Eurocurrency Rate loans is payable at the end of the
applicable interest period (or at three month intervals if the interest period exceeds three months).

The Credit Agreement requires the Borrower to make scheduled quarterly payments on the Euro Term Loan of 0.25% of the original principal amount

of the Euro Term Loan, with any remaining principal payable at maturity. A commitment fee accrues on any unused portion of the revolving loan
commitments under the Credit Agreement at a rate of 0.375% or 0.5% depending on the consolidated total gross leverage ratio at any time of determination.
The Borrower is also obligated to pay other customary fees for a credit facility of this size and type.

On the Closing Date, we and certain of our direct and indirect subsidiaries, as guarantors, provided an unconditional guaranty of all obligations of the

Borrower and the other loan parties arising under the Credit Agreement, the other loan documents and under swap contracts and treasury management
agreements with the lenders or their affiliates (with certain limited exceptions). The Borrower and the guarantors have also granted security interests in
substantially all of their assets to secure such obligations.

The Credit Agreement contains customary affirmative and negative covenants, including covenants limiting the ability of us and our subsidiaries to,

among other things, incur debt, grant liens, make investments, make certain restricted payments, transact with affiliates, and sell assets. The Credit
Agreement also requires us and our subsidiaries to maintain a senior secured net leverage ratio as of the last day of each fiscal quarter of less than or equal to
3.50 to 1.00. We were in compliance with all covenants at October 2, 2021.

We incurred $28.5 million of debt issuance costs related to the Euro Term Loan and $0.5 million of debt issuance costs to the original lenders related to

the First Amendment, which are included in short-term borrowings and current portion of long-term obligations and long-term obligations in the
consolidated balance sheets and will be amortized to interest expense over the seven year life of the Euro Term Loan using the effective interest method,
adjusted to accelerate amortization related to voluntary repayments. We incurred $2.3 million of debt issuance costs in connection with the Revolving Credit
Facility which were capitalized and included in prepaid expenses and other assets in the consolidated balance sheets and will be amortized to interest
expense using the straight-line method over the contractual term of five years of the Revolving Credit Facility.

Additional sources of cash available to us were international currency lines of credit and bank credit facilities totaling $15.0 million as of October 2,

2021, of which $13.1 million was unused and available. These unsecured international credit facilities were used in Europe in fiscal 2021. As of October 2,
2021, we had utilized $1.9 million of the international credit facilities as guarantees in Europe.

We determine if an arrangement contains a lease at inception for arrangements with an initial term of more than 12 months, and classify it as either a

finance or operating lease. We lease certain real and personal property from unrelated third parties under non-cancellable operating leases that expire at
various dates through fiscal 2029. These operating leases are mainly for administrative offices, research-and-development, and manufacturing facilities, as
well as sales offices in various countries around the world. Certain leases require us to pay property taxes, insurance, and routine maintenance, and include
escalation clauses. Many leases include one or more options to renew. We assume renewals in our determination of the lease term when the renewals are
deemed to be reasonably assured at lease commencement. We have also entered into various finance leases to obtain servers and certain other equipment for
our operations. These arrangements are typically for three to six years. Our assets, liabilities, and lease costs related to finance leases are immaterial.

As the rates implicit in our leases are not readily determinable, we use incremental borrowing rates based on the information available at the
commencement date in determining the present value of future lease payments. We consider both the credit rating and the length of the lease when
calculating the incremental borrowing rate. We combine lease and non-lease components into a single lease component for both our operating and finance
leases.

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 generally recognize sublease income on a straight-line basis over the sublease term.

As a result of interim impairment testing performed on long-lived assets in the quarter ended April 4, 2020, we recorded non-cash pre-tax charges
related to the ROU assets of the ILS reporting unit of $1.8 million in the quarter ended April 4, 2020. See Note 8, "Goodwill and Intangible Assets" for
discussion of the interim impairment testing.

In fiscal 2020, we completed a sale-leaseback transaction for our Hamburg, Germany facility in which we sold the buildings for a purchase price, net
of expenses, of $19.6 million and leased back a portion of the facilities with lease terms from 6 to 15 years with early termination provisions after 3 and 5
years, respectively. The sale qualified for sale-leaseback operating lease accounting classification and we recorded a gain, net of selling costs, on the
transaction of $2.2 million, which is recorded

Under our deferred compensation plans ("plans"), eligible employees are permitted to make compensation deferrals up to established limits set under

the plans and accrue income on these deferrals based on reference to changes in available investment options. While not required by the plans, we choose to
invest in insurance contracts and mutual funds in order to approximate the changes in the liability to the employees. These investments and the liability to
the employees were as follows (in thousands):

Cash surrender value of life insurance contracts

Life insurance premiums loads, policy fees, and cost of insurance that are paid from the asset investments and gains and losses from the asset

investments for these plans are recorded as components of other income or expense; such amounts were net gains of $9.8 million in fiscal 2021, $6.1 million
in fiscal 2020, and $1.1 million in fiscal 2019, and fluctuate on a quarterly basis. Changes in the obligation to plan participants are recorded as a component
of operating expenses and cost of sales; such amounts were net losses of $8.9 million in fiscal 2021, $5.3 million in fiscal 2020, and $1.5 million in fiscal
2019, and fluctuate on a quarterly basis. Liabilities associated with participant balances under our deferred compensation plans are affected by individual
contributions and distributions made, as well as gains and losses on the participant's investment allocation election.

Coherent Employee Retirement and Investment Plan

Under the Coherent Employee Retirement and Investment Plan, we match employee contributions to the plan up to a maximum of 4% of the
employee's individual earnings subject to IRS limitations. Employees become eligible for participation and Company matching contributions on their first
day of employment. The Company's contributions (net of forfeitures) during fiscal 2021, 2020, and 2019 were $6.2 million, $6.1 million, and $5.7 million,
respectively.

Employee Stock Purchase Plan

We have an Employee Stock Purchase Plan ("ESPP") whereby eligible employees may authorize payroll deductions of up to 10% of their regular base

salary to purchase shares at the lower of 85% of the fair market value of the common stock on the date of commencement of the offering or on the last day
of the six-month offering period. During fiscal 2021, 2020, and 2019, a total of 120,023 shares, 107,284 shares, and 108,034 shares, respectively, were
purchased by and distributed to employees at an average price of $104.00, $114.54, and $109.32 per share, respectively. At fiscal 2021 year-end, we had
273,442 shares of our common stock reserved for future issuance under the plan.

Stock Award Plans

We maintain stock plans in which employees, service providers, and non-employee directors are eligible participants. The plans, the 2011 Equity
Incentive Plan (the "2011 Plan") and the Equity Incentive Plan (the "2020 Plan"), provide for a number of different equity-based grants, including options,
time-based restricted stock units, and performance restricted stock units. Under the 2011 Plan, Coherent was able to grant options and awards (time-based
restricted stock units and performance restricted stock units), of which grants with respect to 270,371 shares of common stock remained outstanding at fiscal
2021 year-end (calculated at 100% of target amount for performance awards). Under the 2020 Plan, Coherent may grant options and awards (time-based
restricted stock units and performance restricted stock units) to purchase up to 3,080,000 shares of common stock plus any forfeited or cancelled shares
subject to outstanding awards under the 2011 Plan, of which 2,347,532 shares remained available for grant at fiscal 2021 year-end. At fiscal 2021 year-end,
all outstanding stock options and restricted stock units have been issued under plans approved by our shareholders. Following approval of the 2020 Plan by
our shareholders on April 27, 2020, no further grants of awards under the 2011 Equity Incentive Plan were made. However, the 2011 Equity Incentive Plan
will continue to govern awards previously granted under it.

Since adoption of the 2011 Plan and the 2020 Plan, no stock options have been granted to employees. No options are outstanding as of fiscal

2021 year-end.

Non-employee directors are automatically granted time-based restricted stock units upon first joining the Board of Directors and then upon reelection.

New non-employee directors initially receive an award of restricted stock units valued at approximately $225,000 which vest over a two year period. The
annual grant for non-employee directors is a value of approximately $225,000 in shares of restricted stock units that vest on February 15 of the calendar year
following the grant.

Restricted stock awards and restricted stock units are typically subject to vesting restrictions—either time-based, market-based or performance-based
conditions for vesting. Until restricted stock vests, shares (including those issuable upon vesting of the applicable restricted stock unit) are generally subject
to forfeiture if employment or service to the Company terminates prior to the release of restrictions and cannot be transferred.

•

•

•

•

The service-based restricted stock awards generally vest within three years from the date of grant.

The service-based restricted stock unit awards are generally subject to annual vesting over three years from the date of grant, though from
time-to-time, depending upon exceptional circumstances, the Company has granted restricted stock unit awards with one or two year vesting.
For example, the initial grants made to new members of the Board of Directors vest over two years and members of the Board of Directors
have annual grants tied to their reelection to the Board, which vest on the following February 15.

The market-based performance restricted stock unit award grants are generally subject to a single vest measurement three years from the date
of grant, depending upon achievement of performance measurements based on the performance of the Company's total shareholder returns (as
defined in the award) over the performance period compared with the performance of the applicable Russell Index or companies therein (or as
otherwise determined by the Compensation and HR Committee).

The performance restricted stock unit award grants based on goals related to free cash flow target amounts for fiscal 2020 vested as of fiscal
2020 year-end.

We recognize compensation expense for all share-based payment awards based on the fair value of such awards. The expense is recognized on a

straight-line basis per tranche over the respective requisite service period of the awards.

Determining Fair Value

Employee Stock Purchase Plan

Valuation and amortization method—We estimate the fair value of employee stock purchase shares using the Black-Scholes-Merton option-pricing

formula. This fair value is then amortized on a straight-line basis over the purchase period.

Expected Term—The expected term represents the period of our employee stock purchase plan.

Expected Volatility—Our process for computing expected volatility considers both historical volatility and market-based implied volatility; however

our estimate of expected forfeitures is based on historical employee data and could differ from actual forfeitures.

Risk-Free Interest Rate—The risk-free interest rate used in the Black-Scholes-Merton valuation method is based on the implied yield currently

available on U.S. Treasury zero-coupon issues with an equivalent remaining term.

The fair values of shares purchased under the employee stock purchase plan for fiscal 2021, 2020, and 2019 were estimated using the following

Time-Based Restricted Stock Units

Time-based restricted stock units are fair valued at the closing market price on the date of grant.

Performance Restricted Stock Units

We grant performance restricted stock units to officers and certain employees. The performance restricted stock unit agreements provide for the award

of performance stock units with each unit representing the right to receive one share of our common stock to be issued after the applicable award vesting
period. The final number of units awarded, if any, for these performance grants will be determined as of the vesting dates, based upon our total shareholder
return over the performance period compared to the applicable Russell Index or companies therein and could range from no units to a maximum of twice the
initial award units.

The weighted average fair value for the performance units was determined using a Monte Carlo simulation model incorporating the following

weighted average assumptions:

We recognize the estimated cost of these awards, as determined under the simulation model, over the related service period of approximately 3 years,

with no adjustment in future periods based upon the actual shareholder return over the performance period.

In addition, during fiscal 2020, we granted performance restricted stock unit award grants to certain employees with vesting based on goals related to

free cash flow target amounts, with the initial fair value determined based on our closing stock price on the date of grant. Such awards were granted to serve
as a performance incentive with a pay-for-performance forward-looking free cash flow target for the fiscal year in recognition of the impact of the COVID-
19 pandemic. The number of shares issuable under these performance units upon satisfaction of the free cash flow performance criteria was capped at 100%
of target. The total stock-based compensation of these awards was adjusted based on the level of achievement of free cash flow. These awards vested, in the
first quarter of fiscal 2021, at 100% of target.

During fiscal 2021, $7.0 million of stock-based compensation cost was capitalized as part of inventory for all stock plans, $7.7 million was amortized

into cost of sales, and $2.1 million remained in inventory at October 2, 2021. During fiscal 2020, $6.7 million of stock-based compensation cost was
capitalized as part of inventory for all stock plans, $5.3 million was amortized into cost of sales, and $2.8 million remained in inventory at October 3, 2020.

At fiscal 2021 year-end, the total compensation cost related to unvested stock-based awards granted to employees under our stock plans but not yet
recognized was approximately $47.6 million. We do not estimate forfeitures and account for them as they occur. This cost will be amortized on a straight-
line basis over a weighted-average period of approximately 1.4 years.

The stock option exercise tax benefits, if any, are reported in the statement of cash flows. The tax benefits result from tax deductions in excess of the
stock-based compensation cost recognized and are determined on a grant-by-grant basis. We recognized net excess tax benefits from stock award exercises
and restricted stock unit vesting as a discrete tax benefit, which reduced the provision for income taxes by $0.7 million, $0.9 million, and $2.5 million for
fiscal 2021, 2020, and 2019, respectively.

Stock Awards Activity

At fiscal 2019 year-end, we had 24,000 shares subject to vested stock options outstanding. The vested stock options were exercised in fiscal 2020 and

none are outstanding at fiscal 2020 or 2021 year-end.

Service-based restricted stock units vested during each fiscal year. Performance-based restricted stock units are included at 100% of target goal. Under the terms of
the market-based awards, the recipient may earn between 0% and 200% of the award. Under the terms of the fiscal 2020 performance-based awards based on free
cash flow targets, the recipient may earn between 0% and 100% of the award.

Restricted stock units are converted into the right to receive common stock upon vesting; prior to issuance, the Company permits the employee holders

to satisfy their tax withholding requirements by net settlement, whereby the Company withholds a portion of the shares to cover the applicable taxes based
on the fair market value of the Company's stock at the vesting date. The number of shares withheld to cover tax payments was 80,605 in fiscal 2021, 88,000
in fiscal 2020, and 120,000 in fiscal 2019; tax payments made were $10.4 million, $13.5 million, and $15.2 million, respectively.

13. COMMITMENTS AND CONTINGENCIES

Indemnifications

In the normal course of business, we enter into agreements that contain a variety of representations and warranties and provide for general

indemnification. Exposure under these agreements is unknown because claims may be made against us in the future and we may record charges in the future
as a result of these indemnification obligations. As of October 2, 2021, we did not have any material indemnification claims that were probable or
reasonably possible.

Commitments

We maintain commitments to purchase inventory from our suppliers as well as fixed assets, services and other assets in the ordinary course of business.

As of October 2, 2021, we had total estimated significant purchase commitments for inventory of approximately $63.8 million and significant purchase
obligations for fixed assets and services of $50.6 million.

Legal Proceedings

We are subject to legal claims and litigation arising in the ordinary course of business, such as contract-related, product sales and servicing, real estate,

product liability, regulatory matters, employment or intellectual property claims.

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

13. COMMITMENTS AND CONTINGENCIES (continued)

Although we do not expect that such claims and litigation will ultimately have a material adverse effect on our consolidated financial position, results

of operations or cash flows, an adverse result in one or more matters could negatively affect our results in the period in which they occur, or in future
periods.

The United States and many foreign governments impose tariffs and duties on the import and export of certain products we sell and purchase. From
time to time our customs compliance, product classifications, duty calculations, and payments are reviewed or audited by government agencies. Any adverse
result in such a review or audit could negatively affect our results in the period in which they occur, or in future periods.

German authorities are currently investigating an export compliance matter involving one of our German subsidiaries involving four former employees

(whose employment was terminated following our discovery of this matter). While under German law the subsidiary can be held liable for certain
infringements by its employees of German export control laws we believe that this matter involves less than approximately 1.5 million Euros in transactions
in the period currently under investigation and do not believe that the final resolution of this matter will be material to our consolidated financial position,
results of operations or cash flows. However, the German government investigation is ongoing and it is possible that substantial payments, fines, penalties or
damages could result. Even though we do not currently expect this matter to be material to our consolidated financial position, results of operations or cash
flows, circumstances could change as the investigation progresses.

disclosures in the S-4/A (Waterman v. Coherent, Inc., et al., Case No. 2:21-cv-02623). Specifically, the complaint challenges the disclosures relating to the
analyses of the Company's financial advisors, BofA Securities and Credit Suisse. Among other things, the complaint alleges that the S-4 fails to disclose
details about the bankers' precedent transactions analyses, price targets analyses, and DCF analyses. The complaint seeks, among other relief, a preliminary
injunction to prevent further advancement of the transaction and a direction to the director defendants to disseminate a true and non-misleading Registration
Statement. The case was voluntarily dismissed on July 8, 2021.

As previously disclosed in the Company's Quarterly Report on Form 10-Q for the quarterly period ended July 3, 2021, filed with the SEC on August

11, 2021, on June 11, 2021, a purported stockholder of the Company filed a complaint in the United States District Court for the Northern District of
California against the Company and members of its board of directors alleging violations of the federal securities laws for misleading and incomplete
disclosures in the S-4/A (Anderson v. Coherent, Inc., et al., Case No. 5:21-cv-04505). Specifically, the complaint challenges the disclosures relating to
Coherent's and II-VI's financial projections and the analyses of the Company's financial advisors, BofA Securities and Credit Suisse. Among other things,
the complaint alleges that the projections should have provided a reconciliation of non-GAAP financial measures to GAAP, that the S-4 fails to disclose
details about the bankers' precedent transactions analyses and DCF analyses and that there was insufficient disclosure regarding the discretionary payment of
$3.0 million to Credit Suisse at the closing of the merger. The complaint seeks, among other relief, a preliminary injunction to prevent further advancement
of the transaction and a direction to the director defendants to disseminate a true and non-misleading Registration Statement. The case was voluntarily
dismissed on July 8, 2021.

Income Tax Audits

We are subject to taxation and file income tax returns in the U.S. federal jurisdiction and in many state and foreign jurisdictions. Our most significant

tax jurisdictions are the U.S. and Germany. For U.S. federal and German income tax purposes, all years prior to fiscal 2018 and 2011, respectively, are
closed to examination. In our other major foreign jurisdictions and our major state jurisdictions, the years prior to fiscal 2015 and 2017, respectively, are
closed. Earlier years in our various jurisdictions may remain open for adjustment to the extent that we have tax attribute carryforwards from those years.

In October 2021, we received a final audit report for our entities that were under audit in Germany for the years 2011 through 2016. The German tax
authorities issued transfer pricing adjustments related to various intercompany transactions with our South Korean and Singapore entities. The adjustments
related to transactions with our South Korean entity are being appealed and contested through the Competent Authority process with South Korea. The
South Korean tax authorities had previously performed an audit focused on intercompany transfer pricing arrangements for fiscal years 2014 through 2017
related to our German and U.S. entities. In May 2019, they issued transfer pricing assessments for taxes, royalties and sales commissions and we are
appealing and contesting these amounts through the Competent Authority process between South Korea, Germany and the United States. Accordingly, there
is no change to our tax position at the time of filing of this annual report. We are continuing to monitor and evaluate this situation.

In October 2020, the South Korean tax authorities also commenced an internal review of our initial and second High-Tech tax exemptions approved in

fiscal 2013 and 2016, respectively. In March 2021 we agreed with the tax authorities change in timing for claiming the tax exemption benefits.

13. COMMITMENTS AND CONTINGENCIES (continued)

The timing and the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if any, upon resolution of the issues

raised by the taxing authorities may differ materially from the amounts accrued for each year. Management believes that it has adequately provided for any
adjustments that may result from tax examinations. We regularly engage in discussions and negotiations with tax authorities regarding tax matters in various
jurisdictions. Although the timing of resolution, settlement and closure of audits is not certain, we do not believe it is reasonably possible that our
unrecognized tax benefits will materially change in the next 12 months.

Other Tax Matters

From time to time, we are subject to review, audit or other examination related to taxes other than income taxes. While we are not currently subject to

any such matters which we expect to have a material adverse effect on our financial condition and operating results, it is possible that an adverse final
conclusion to any such other tax matters could lead to a material adverse effect on our financial condition and operating results.

14. STOCK REPURCHASES

On October 28, 2018, our board of directors authorized a stock repurchase program authorizing the Company to repurchase up to $250.0 million of our

common stock through December 31, 2019, with a limit of no more than $75.0 million per quarter. During fiscal 2019, we repurchased and retired 603,828
shares of outstanding common stock under this program at an average price of $128.20 per share for a total of $77.4 million. We made no repurchases under
the program during our first quarter of fiscal 2020 and the program expired on December 31, 2019.

On February 5, 2020, our board of directors authorized a stock repurchase program authorizing the Company to repurchase up to $100.0 million of our

common stock through January 31, 2021.We made no repurchases under the program during fiscal 2020 or 2021.

Effective tax rate

7.6 %

6.5 %

10.4 %

Our effective tax rate on loss before income taxes for fiscal 2021 of 7.6% was lower than the U.S. federal tax rate of 21.0%. Our effective tax rate
benefit for fiscal 2021 was unfavorably impacted primarily due to the establishment of valuation allowances on certain deferred tax assets, income in foreign
jurisdictions subject to tax rates that are higher than the U.S. tax rates, stock-based compensation not deductible for tax purposes and limitations on the
deductibility of compensation under Internal Revenue Code Section 162(m) and the deferred taxes on foreign earnings not considered permanently
reinvested, partially offset by the benefit of federal research and development tax credits, our Singapore tax exemption and the benefit of our FDII
deduction.

Our results reflect the payment of a termination fee of $217.6 million to Lumentum in fiscal 2021. This amount was deducted for book purposes in the

current year and treated as a future deductible expense for tax purposes in accordance with our accounting policy.

The effective tax rate on loss before income taxes for fiscal 2020 of 6.5% was lower than the U.S. federal tax rate of 21.0%. Our effective tax benefit

for fiscal 2020 was unfavorably impacted primarily due to the impairment of goodwill that is not deductible for tax purposes and the establishment of
valuation allowances for certain deferred tax assets. These unfavorable impacts were partially offset primarily from the release of unrecognized tax benefits
net of settlements and competent authority offsets and losses in foreign jurisdictions subject to tax rates that are higher than the U.S. tax rates.

In September 2021, Coherent Singapore received an amended Pioneer Status tax exemption from the Singapore authorities effective from fiscal 2022

through fiscal 2026. The tax holiday continues to be conditional upon our meeting certain revenue, business spending and employment thresholds. The
impact of this tax exemption decreased Coherent Singapore income taxes by approximately $3.7 million, $2.6 million, and $3.9 million in fiscal 2021, fiscal
2020, and fiscal 2019, respectively. The benefits of the tax holiday on net income (loss) per diluted share were $0.15, $0.11, and $0.16, respectively.

In determining our fiscal 2021 and 2020 tax provisions under ASC 740, we calculated the deferred tax assets and liabilities for each separate tax entity.

We then considered a number of factors including the positive and negative evidence regarding the realization of our deferred tax assets to determine
whether a valuation allowance should be recognized with respect to our deferred tax assets. We determined that a valuation allowance was appropriate for a
portion of the deferred tax assets of our California and certain state research and development tax credits and certain foreign deferred taxes, including
foreign tax attributes and foreign net operating losses.

During fiscal 2021, we increased our valuation allowance on deferred tax assets by $15.5 million to $73.2 million, primarily due to certain foreign

deferred tax assets and California (and other) state research and development tax credits which are not expected to be recognized. At October 2, 2021, we
had U.S. federal deferred tax assets related to research and development credits, foreign tax credits and other tax attributes that can be used to offset federal
taxable income in future periods. These credit carryforwards will expire if they are not used within certain time periods. Management determined that there
is sufficient positive evidence to conclude that it is more likely than not that sufficient taxable income will exist in the future allowing us to recognize these
deferred tax assets.

Foreign gross net operating loss carryforwards are $132.9 million, of which $98.8 million have no expiration date and $34.1 million have
various expiration dates beginning in fiscal 2023. Among the total of $132.9 million foreign net operating loss carryforwards, a valuation
allowance of $128.0 million has been provided for certain jurisdictions since the recovery of the carryforwards is uncertain. U.S. federal and
certain state gross net operating loss carryforwards are $10.1 million and $30.4 million, respectively, which were acquired from our
acquisitions. A full valuation allowance against certain state net operating losses of $30.4 million has been recorded.

U.S. federal R&D credit carryforwards of $38.4 million are scheduled to expire beginning in fiscal 2026. California R&D credit carryforwards
of $34.9 million have no expiration date. A total of $29.4 million valuation allowance, before U.S. federal benefit, has been recorded against
California R&D credit carryforwards of $34.9 million since the recovery of the carryforwards is uncertain. Other states R&D credit
carryforwards of $4.3 million are scheduled to expire beginning in fiscal 2022. A valuation allowance totaling $3.8 million, before U.S. federal
benefit, has been recorded against certain state R&D credit carryforwards of $4.3 million since the recovery of the carryforwards is uncertain.

U.S. federal foreign tax credit carryforwards of $38.4 million are scheduled to expire beginning in fiscal 2028.

We are subject to taxation and file income tax returns in the U.S. federal jurisdiction and in many state and foreign jurisdictions. Our most significant

tax jurisdictions are the U.S. and Germany. For U.S. federal and German income tax purposes, all years prior to fiscal 2018 and 2011, respectively, are
closed to examination. In our other major foreign jurisdictions and our major state jurisdictions, the years prior to fiscal 2015 and 2017, respectively, are
closed. Earlier years in our various jurisdictions may remain open for adjustment to the extent that we have tax attribute carryforwards from those years.

In October 2021, we received a final audit report for our entities that were under audit in Germany for the years 2011 through 2016. The German tax
authorities issued transfer pricing adjustments related to various intercompany transactions with our South Korean and Singapore entities. The adjustments

 As a result of the Rofin acquisition in fiscal 2017, we assumed all assets and liabilities of Rofin's defined benefit plans for the Rofin-Sinar Laser,
GmbH ("RSL") and Rofin-Sinar Inc. ("RS Inc.") employees. The U.S. plan began in fiscal 1995 and is partially funded. Any new employees hired after
January 1, 2007, are not eligible for the RS Inc. pension plan. As is the customary practice with German companies, the German pension plan is
unfunded. Any new employees hired after 2000 are not eligible for the RSL pension plan. The measurement date of these pension plans is September 30 and
actuarial gains and losses are deferred into OCI and amortized over future periods.

Effective January 1, 2012, the RS Inc. defined benefit plan was amended to exclude highly compensated employees, as defined by the Internal
Revenue Service, from receiving future years of service under the RS Inc. defined benefit plan. A non-qualified defined benefit plan was created to replace
the benefits lost by the employees that were otherwise excluded from the qualified defined benefit plan. Effective August 31, 2018, both the RS Inc. plans
were amended to freeze all future compensation benefit accruals. During fiscal 2020, we opened a lump sum payment election window for the RS Inc.

benefit plan to allow certain participants the option to receive the entire value of their benefit as a single lump sum payment, resulting in payments of
$1.0 million in fiscal 2020.

In addition, we have defined benefit plans in South Korea, Japan, Spain, and Italy, covering all full-time employees with at least one year of service,

and a defined benefit plan in Germany covering two individuals. As is the customary practice with European and Asian companies, the plans are unfunded,
with the exception of the Spanish plan which is partially funded. We have elected to recognize all actuarial gains and losses on these plans immediately, as
incurred. The measurement date of these defined benefit plans is September 30.

For financial reporting purposes, the calculation of net periodic pension costs is based upon a number of actuarial assumptions including a discount

rate for plan obligations, an assumed rate of return on pension assets and an assumed rate of compensation increase for employees covered by the plan. All
of these assumptions were based upon management's judgment, considering all known trends and uncertainties. Actual results that differ from these
assumptions would impact future expense recognition and the cash funding requirements of our defined benefit plans.

Components of net periodic cost are as follows for fiscal 2021, 2020, and 2019 (in thousands):

We recognize the over (under) funded status of the defined benefit plans in our consolidated balance sheets. We also recognize, in other comprehensive
income (loss), certain gains and losses that arise for the period but are deferred under current pension accounting rules. A one percent change in the discount
rate or the expected rate of return on plan assets would not have a material impact on the projected benefit obligation or the net periodic benefit cost. The
decrease in discount rates for U.S. and foreign plans was the primary reason for the assumption change and the increase in the projected benefit obligation.

We employ a total return investment approach whereby a mix of equity, debt securities and government securities are used to maximize the long-term

return of plan assets for a prudent level of risk. The intent of this strategy is to minimize plan expenses by maximizing investment returns within that prudent
level of risk. Furthermore, equity investments are diversified across U.S. and non-U.S. stocks as well as growth, value and small and large
capitalizations. Additionally, cash balances are

maintained at levels adequate to meet near-term plan expenses and benefit payments. Investment risk is measured and monitored on an ongoing basis
through semi-annual investment portfolio reviews.

Investments in our defined benefit plan are stated at fair value. Level 1 assets are valued using quoted market prices that represent the asset value of the

shares held by the trusts. The level 2 assets are investments in pooled funds, which are valued using a model to reflect the valuation of their underlying
assets that are publicly traded with observable values. The fair value of level 3 pension plan assets are measured by compiling the portfolio holdings and
independently valuing the securities in those portfolios.

The fair values of our pension plan assets, by level within the fair value hierarchy, at October 2, 2021 are as follows:

18. SEGMENT AND GEOGRAPHIC INFORMATION

We are organized into two reporting segments, OLS and ILS, based upon our organizational structure and how the CODM receives and utilizes
information provided to allocate resources and make decisions. This segmentation reflects the go-to-market strategies and synergies for our broad portfolio
of laser technologies and products. While both segments deliver cost-effective, highly reliable photonics solutions, the OLS business segment is focused on
high performance laser sources and complex optical sub-systems, typically used in microelectronics manufacturing, medical diagnostics, and therapeutic
applications, as well as in scientific research. Our ILS business segment delivers high performance laser sources, sub-systems, and machine tools primarily
used for industrial laser materials processing, serving important end markets like automotive, machine tools, consumer goods, and medical device
manufacturing as well as applications in aerospace and defense.

We have identified OLS and ILS as operating segments for which discrete financial information is available. Both units have dedicated engineering,

manufacturing, product business management, and product line management functions. A small portion of our outside revenue is attributable to projects and
recently developed products for which a segment has not yet been determined. The associated direct and indirect costs are presented in the category of
Corporate and other, along with other corporate costs as described below.

Our Chief Executive Officer has been identified as the CODM, as he assesses the performance of the segments and decides how to allocate resources
to the segments. Income (loss) from operations is the measure of profit and loss that our CODM uses to assess performance and make decisions. Assets by
segment are not a measure used to assess the performance of the company by the CODM and thus are not reported in our disclosures. Income (loss) from
operations represents the net sales less the cost of sales and direct operating expenses incurred within the operating segments as well as allocated expenses
such as shared sales and manufacturing costs. We do not allocate certain operating expenses to our operating segments and we manage them at the corporate
level. These unallocated costs include stock-based compensation and corporate functions (certain management, finance, legal, and human resources) and are
included in the results below under Corporate and other in the reconciliation of operating results. Management does not consider unallocated Corporate and
other costs in its measurement of segment performance.

The following table provides net sales and income (loss) from operations for our operating segments and a reconciliation of our total income (loss)

from operations to income (loss) before income taxes (in thousands):

19. RESTRUCTURING CHARGES

In June 2019, we announced our plans to exit a portion of our HPFL business and consolidate all HPFL manufacturing and engineering functions in

our Tampere, Finland facility by transferring certain HPFL activities from our Hamburg, Germany facility. We recorded charges in fiscal 2020 of $1.1
million, primarily related to accelerated depreciation and project

management consulting. We recorded no charges related to this project in fiscal 2021 as the project was completed in fiscal 2020.

We also vacated our leased facility in Santa Clara at the end of the lease term on July 31, 2020 and combined operations into our owned Santa Clara

headquarters. We incurred costs in fiscal 2021 and 2020 of $0.1 million and $1.5 million, respectively, primarily related to accelerated depreciation, and
completed the project in fiscal 2021. We also incurred costs in fiscal 2020 of $0.1 million for other projects.

In the fourth quarter of fiscal 2020, we began a restructuring program in our ILS segment which includes management reorganizations, the planned

closure of multiple manufacturing sites, and the right-sizing of global sales, service, order admin, marketing communication and certain administrative
functions, among others. In the fourth quarter of fiscal 2020, we incurred costs of $2.6 million, primarily related to severance. In fiscal 2021, we incurred
costs of $12.2 million, primarily related to write-offs of excess inventory, accruals for vendor commitments and warranty provisions, which are recorded in
cost of sales, estimated severance, facility exit costs and accelerated depreciation.

The following table presents our current liability as accrued on our balance sheets for restructuring charges. The table sets forth an analysis of the

At October 2, 2021, $1.4 million of accrued severance related and other costs were included in other current liabilities. The severance, asset write-offs

for inventory, accruals for vendor commitments, warranty provisions, facility exit costs, accelerated depreciation and other costs in fiscal 2021 primarily
related to the restructuring program that began in the fourth quarter of fiscal 2020. The asset write-offs for accelerated depreciation and other costs in fiscal
2020 primarily related to the exit of a portion of our HPFL business in Hamburg, Germany, and costs to vacate our leased facility in Santa Clara and
combine operations into our owned Santa Clara headquarters. The severance related costs in fiscal 2020 primarily related to the restructuring program that
began in the fourth quarter of fiscal 2020.

By segment, $12.2 million and $3.9 million of restructuring costs were incurred in the ILS segment and $0.1 million and $1.4 million were incurred in

the OLS segment in fiscal 2021 and 2020, respectively. Restructuring charges are recorded in cost of sales, research and development and selling, general
and administrative expenses in our consolidated statements of operations.

STATEMENT OF MANAGEMENT RESPONSIBILITY

Management is responsible for the preparation, integrity, and objectivity of the Consolidated Financial Statements and other financial information

included in the Company's 2021 Annual Report on Form 10-K. The Consolidated Financial Statements have been prepared in conformity with U.S.
generally accepted accounting principles and reflect the effects of certain estimates and judgments made by management. It is critical for investors and other
readers of the Consolidated Financial Statements to have confidence that the financial information that we provide is timely, complete, relevant and accurate.

Management, with oversight by the Company's Board of Directors, has established and maintains a corporate culture that requires that the Company's

affairs be conducted to the highest standards of business ethics and conduct. Management also maintains a system of internal controls that is designed to
provide reasonable assurance that assets are safeguarded and that transactions are properly recorded and executed in accordance with management's
authorization. This system is regularly monitored through direct management review, as well as extensive audits conducted by internal auditors throughout
the organization.

Our Consolidated Financial Statements as of and for the year ended October 2, 2021 have been audited by Deloitte & Touche LLP, an independent
registered public accounting firm. Their audit was conducted in accordance with the standards of the Public Company Accounting Oversight Board (United
States) and included an integrated audit under such standards.

The Audit Committee of the Board of Directors meets regularly with management, the internal auditors and the independent registered public
accounting firm to review accounting, reporting, auditing and internal control matters. The Audit Committee has direct and private access to both internal
and external auditors.

See Item 9A for Management's Report on Internal Control Over Financial Reporting.

We are committed to enhancing shareholder value and fully understand and embrace our fiduciary oversight responsibilities. We are dedicated to
ensuring that our high standards of financial accounting and reporting as well as our underlying system of internal controls are maintained. Our culture
demands integrity and we have the highest confidence in our processes, internal controls, and people, who are objective in their responsibilities and operate
under the highest level of ethical standards.

ITEM 9A.    CONTROLS AND PROCEDURES

Management's Evaluation of Disclosure Controls and Procedures

We have evaluated the effectiveness of the design and operation of our disclosure controls and procedures, as such term is defined in Rule 13a-15(e)

under the Securities Exchange Act of 1934, as of the end of the period covered by this annual report ("Evaluation Date"). The controls evaluation was
conducted under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer. Based on this
evaluation, our Chief Executive Officer and Chief Financial Officer concluded as of the Evaluation Date that our disclosure controls and procedures were
effective in providing reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Securities Exchange
Act of 1934, as amended, is (i) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange
Commission's rules and forms and (ii) accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial
Officer, as appropriate, to allow timely decisions regarding required disclosures.

Management's Report on Internal Control Over Financial Reporting

Management, including our Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining adequate internal

control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the Company.

Management assessed the effectiveness of our internal control over financial reporting as of October 2, 2021, utilizing the criteria set forth by the
Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in Internal Control-Integrated Framework (2013). Based on the assessment
by management, we determined that our internal control over financial reporting was effective as of October 2, 2021. The effectiveness of our internal
control over financial reporting as of October 2, 2021 has been audited by Deloitte & Touche LLP, our independent registered public accounting firm, as
stated in their report which appears below.

Inherent Limitations Over Internal Controls

Management, including our CEO and CFO, does not expect that our internal controls will prevent or detect all errors and all fraud. A control system,
no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further,
the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs.
Because of the inherent limitations in all control systems, no evaluation of internal controls can provide absolute assurance that all control issues and
instances of fraud, if any, have been detected. Also, any evaluation of the effectiveness of controls in future periods are subject to the risk that those internal
controls may become inadequate because of changes in business conditions, or that the degree of compliance with the policies or procedures may
deteriorate.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect,

our internal control over financial reporting during the three months ended October 2, 2021.

121

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Coherent, Inc.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Coherent, Inc. and subsidiaries (the “Company”) as of October 2, 2021, based on
criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission
(COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of October 2, 2021, based on
criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the
consolidated financial statements as of and for the year ended October 2, 2021, of the Company and our report dated November 29, 2021, expressed an
unqualified opinion on those consolidated financial statements.

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.

EQUITY INCENTIVE PLAN

GLOBAL RESTRICTED STOCK UNIT AGREEMENT

Exhibit 10.15

1.

Grant.    The  Company  hereby  grants  to  the  Employee  named  in  the  Notice  of  Grant  of  Award  and  Award  Agreement  (the  “Notice  of
Grant”) an award of Restricted Stock Units (“RSUs”), as set forth in the Notice of Grant, subject to the terms and conditions in this agreement, including the
additional  terms  and  restrictive  covenant  conditions  contained  in  the  appendix  attached  hereto  (the  “Appendix”  and,  together  with  the  Global  Restricted
Stock  Unit  Agreement,  the  “Agreement”)  and  in  the  Company’s  Equity  Incentive  Plan  (the  “Plan”).  Capitalized  terms  used  and  not  defined  in  this
Agreement shall have the meaning set forth in the Plan.

2.

Company’s Obligation.  Each RSU granted represents the right to receive one Share on the vesting date.  Unless and until the RSUs vest,
the Employee will have no right to receive Shares under such RSUs.  Prior to actual distribution of Shares pursuant to any vested RSUs, such RSUs will
represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company.

3.

Vesting Schedule.  The RSUs shall vest as set forth in the Notice of Grant, subject to paragraph 4 and the Appendix.

4.

Termination as a Service Provider.  If the Employee terminates service as a Service Provider because of death or Disability prior to the
date the RSUs would otherwise vest if the Employee had remained a Service Provider, such RSUs shall become vested upon such termination of service as a
Service  Provider  because  of  such  death  or  Disability.  For  purposes  of  this  Agreement,  “Disability”  means  when  the  Employee  as  a  result  of  sickness  or
injury is unable to perform with reasonable continuity the substantial and material acts necessary to pursue the Employee’s usual occupation.

Notwithstanding any contrary provision of this Agreement or the Notice of Grant, if the Employee terminates service as a Service Provider for any
or  no  reason  other  than  death  or  Disability  prior  to  vesting,  the  unvested  RSUs  awarded  by  this  Agreement  will  thereupon  be  forfeited  at  no  cost  to  the
Company. [For purposes of clarification, the preceding sentence does not override the accelerated vesting as set forth in the Company’s Change of Control
and Leadership Change Severance Plan.]

For  purposes  of  the  RSUs,  the  Service  Provider’s  service  will  be  considered  terminated  as  of  the  date  that  the  Service  Provider  is  no  longer
providing services to the Company or one of its Subsidiaries (regardless of the reason for such termination and whether or not later to be found invalid or in
breach of employment laws in the jurisdiction where the Employee is employed or the terms of the Employee’s employment agreement, if any), and unless
otherwise expressly provided in this Agreement or determined by the Company, the Service Provider’s right to vest in the RSUs under the Plan, if any, will
terminate as of such date and will not be extended by any notice period (e.g., the Employee’s period of service would not include any contractual notice
period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where the Employee is employed or the terms
of the Employee’s employment agreement, if any); the Company shall have the exclusive discretion to determine when the Service Provider is no longer
providing services for purposes of the RSUs (including whether the Service Provider may still be considered to be providing services while on a leave of
absence).

5.

Settlement upon Vesting.  Any RSUs that vest in accordance with paragraph 3 or 4 will be distributed to the Employee (or in the event of

the Employee’s death, to his or her estate) in Shares.

6.

Responsibility for Taxes.  The Employee acknowledges and agrees that, regardless of any action taken by the Company or, if different, the
Employee’s employer (the “Employer”), the ultimate liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or
other tax-related items related to the Employee’s participation in the Plan and legally applicable to the Employee (“Tax-Related Items”) is and remains the
Employee’s responsibility and may exceed the amount (if any) withheld by the Company or the Employer. The  Employee  further  acknowledges  that  the
Company and/or the Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect
of the RSUs, including, but not limited to, the grant, vesting or settlement of the RSUs, the receipt of any dividends on Shares, and the subsequent sale of the
Shares;  and  (ii)  do  not  commit  to  and  are  under  no  obligation  to  structure  the  terms  of  the  grant  or  any  aspect  of  the  RSUs  to  reduce  or  eliminate  the
Employee’s  liability  for  Tax-Related  Items  or  achieve  any  particular  tax  result.    Further,  if  the  Employee  has  become  subject  to  tax  in  more  than  one
jurisdiction, the

Page 1

Employee acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related
Items in more than one jurisdiction.

Prior  to  any  relevant  taxable  or  tax  withholding  event,  as  applicable,  the  Employee  will  pay  or  make  adequate  arrangements  satisfactory  to  the
Company and/or the Employer to satisfy all Tax-Related Items. In this regard, the Company shall withhold in Shares otherwise deliverable to the Employee
having a Fair Market Value equal to an amount that satisfies the Tax-Related Items required to be withheld. In the event that such withholding in Shares is
problematic under applicable tax, securities or other laws, or has materially adverse accounting consequences, the Employee authorizes the Company and/or
the Employer, or their respective agents, at their discretion, to satisfy their withholding obligations, if any, with regard to all Tax-Related Items by one or a
combination of the following:

a.

withholding from the Employee’s wages or cash compensation paid to the Employee by the Company and/or the Employer; or

through a mandatory sale arranged by the Company (on the Employee’s behalf pursuant to this authorization without further consent).

b.

withholding from proceeds of the sale of Shares acquired upon vesting/settlement of the RSUs either through a voluntary sale or

The  Company  may  withhold  or  account  for  Tax-Related  Items  by  considering  statutory  withholding  rates  or  other  withholding  rates,  including
maximum rates applicable in the Employee’s jurisdiction, in which case the Employee may receive a refund of any over-withheld amount in cash and will
have no entitlement to the equivalent amount in Shares. If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, the
Employee is deemed to have been issued the full number of Shares subject to the vested RSUs, notwithstanding that a number of the Shares are held back
solely for the purpose of paying the Tax-Related Items .

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

7.

Rights  as  Stockholder.    Neither  the  Employee  nor  any  person  claiming  under  or  through  the  Employee  will  have  any  of  the  rights  or
privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares will have
been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to the Employee or the Employee’s broker.

8.

Acknowledgements.  In accepting the grant of RSUs, the Employee acknowledges, understands and agrees that:

the Company (and not the Employee’s employer) is granting the RSU. The Company will administer the Plan from outside the
Employee’s country of residence if the Employee’s country of residence is outside the United States, and the provisions of this Agreement will be governed
by, and subject to, the internal substantive laws, but not the choice of law rules, of the State of Delaware;

no claim or entitlement to compensation or damages shall arise from forfeiture of the RSUs resulting from the termination of the

the grant of the RSUs is voluntary and occasional and does not create any contractual or other right to receive future grants of

the Plan is established voluntarily by the Company, it is discretionary in nature, and it may be modified, amended, suspended, or

the  grant  of  RSUs  and  the  Employee’s  participation  in  the  Plan  shall  not  create  a  right  to  employment  or  other  service  or  be
interpreted  as  forming  an  employment  or  service  contract  with  the  Company  and  shall  not  interfere  with  the  ability  of  the  Employer  to  terminate  the
Employee’s employment or other service relationship (if any) at any time;

l.

m.

unless otherwise provided in the Plan or by the Company in its discretion or [in the Agreement and Plan of Merger, dated as of
March 25, 2021, by and among the Company, II-VI Incorporated and Watson Merger Sub Inc.], the RSUs and the benefits evidenced by this Agreement do
not create any entitlement to have the RSUs or any such benefits transferred to, or assumed by, another company nor be exchanged, cashed out or substituted
for, in connection with any corporate transaction affecting the Shares; and

neither  the  Company,  the  Employer  nor  any  Subsidiary shall  be  liable  for  any  foreign  exchange  rate  fluctuation  between  the
Employee’s  local  currency  and  the  United  States  Dollar  that  may  affect  the  value  of  the  RSUs  or  of  any  amounts  due  to  the  Employee  pursuant  to  the
settlement of the RSUs or the subsequent sale of any Shares acquired upon settlement.

n.

Data Privacy Information and Consent. 

a.

Data Collection and Usage. The Company and the Employer may collect, process and use certain personal information about
the  Employee,  including,  but  not  limited  to,  the  Employee’s  name,  home  address,  telephone  number,  email  address,  date  of  birth,  social  insurance
number,  passport  or  other  identification  number,  salary,  nationality,  job  title,  any  Shares  or  directorships  held  in  the  Company,  details  of  all  awards
granted  under  the  Plan  or  any  other  entitlement  to  Shares  awarded,  canceled,  exercised,  vested,  unvested  or  outstanding  in  the  Employee’s  favor
(“Data”), for the purposes of implementing, administering and managing the Employee’s participation in the Plan. The legal basis, where required, for
the processing of Data is the Employee’s consent.

b.

Stock Plan Administration Service Providers. The Company transfers Data to E*TRADE Financial Corporate Services, Inc.
and certain of its affiliated companies (“E*TRADE”), an independent service provider based in the United States which is assisting the Company with
the implementation, administration and management of the Plan. The Company may select a different service provider or additional service providers
and  share  Data  with  such  other  provider  serving  in  a  similar  manner.  The  Employee  may  be  asked  to  agree  on  separate  terms  and  data  processing
practices with the service provider, with such agreement being a condition to the ability to participate in the Plan.

International  Data  Transfers.  The  Company  and  E*TRADE  are  based  in  the  United  States.  The  Employee’s  country  or
jurisdiction  may  have  different  data  privacy  laws  and  protections  than  the  United  States.  The  Company’s  legal  basis  for  the  transfer  of  Data,  where
required, is the Employee’s consent.

c.

Employee’s participation in the Plan, or as required to comply with legal or regulatory obligations, including under tax and security laws.

d.

Data Retention. The Company will hold and use Data only as long as is necessary to implement, administer and manage the

Page 3

e.

Voluntariness and Consequences of Consent Denial or Withdrawal. Participation in the Plan is voluntary and the Employee
is providing the consents herein on a purely voluntary basis. If the Employee does not consent, or if the Employee later seeks to revoke the consent, his
or  her  salary  from  or  employment  with  the  Employer  will  not  be  affected;  the  only  consequence  of  refusing  or  withdrawing  the  consent  is  that  the
Company would not be able to grant the Employee awards under the Plan or administer or maintain such awards.

f.

Data  Subject  Rights.  The  Employee  may  have  a  number  of  rights  under  data  privacy  laws  in  his  or  her  jurisdiction.
Depending  on  where  the  Employee  is  based,  such  rights  may  include  the  right  to  (i)  request  access  to  or  copies  of  Data  the  Company  processes,  (ii)
rectify  incorrect  Data,  (iii)  delete  Data,  (iv)  restrict  the  processing  of  Data,  (v)  restrict  the  portability  of  Data,  (vi)  lodge  complaints  with  competent
authorities  in  the  Employee’s  jurisdiction,  and/or  (vii)  receive  a  list  with  the  names  and  addresses  of  any  potential  recipients  of  Data.  To  receive
clarification regarding these rights or to exercise these rights, the Employee can contact his or her local human resources representative.

g.

Additional Legal Basis. The Employee understands that the Company may rely on a different legal basis for the collection,
processing or transfer of Data in the future and/or request the Employee to provide another data privacy consent. If  applicable,  upon  request  of  the
Company or the Employer, the Employee agrees to provide an executed data privacy consent form to the Company and/or the Employer (or any other
agreements  or  consents  that  may  be  required  by  the  Company  and/or  the  Employer)  that  the  Company  and/or  the  Employer  may  deem  necessary  to
obtain from the Employee for the purpose of administering his or her participation in the Plan in compliance with the applicable data privacy laws,
either now or in the future. The Employee understands and agrees that he or she will not be able to participate in the Plan if he or she fails to provide
any such consent or agreement requested by the Company and/or the Employer.

10.

No  Advice  Regarding  Grant.    The  Company  is  not  providing  any  tax,  legal,  or  financial  advice,  nor  is  the  Company  making  any
recommendations  regarding  the  Employee’s  participation  in  the  Plan  or  the  Employee’s  acquisition  or  sale  of  Shares.    The  Employee  should  therefore
consult with his or her own personal tax, legal, and financial advisors regarding the Employee’s participation in the Plan before taking any action related to
the Plan.

11.

Language.    The  Employee  has  received  the  terms  and  conditions  of  this  Agreement  and  any  other  related  communications,  and  the
Employee consents to having received these documents, in English. If the Employee has received this Agreement or any other communications related to the
Plan translated into a language other than English, and if the meaning of the translated version is different from the English version, the English version will
control.

12.

Electronic Delivery & Acceptance.  The Company may, in its sole discretion, decide to deliver any documents related to current or future
participation in the Plan by electronic means.  The Employee hereby consents to receive such documents by electronic delivery and agrees to participate in
the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company.

13.

Address for Notices.  Any notice to be given to the Company under the terms of this Agreement shall be addressed to the Company, in
care of Stock Plan Administration at Coherent, Inc., 5100 Patrick Henry Drive, Santa Clara, CA 95054 U.S.A., or at such other address as the Company may
hereafter designate in writing.

14.

Conditions for Issuance of Shares.  The Shares deliverable upon vesting of the RSUs may be either previously authorized but unissued
Shares or issued Shares that have been reacquired by the Company.  The Company shall not be required to issue any Shares hereunder prior to fulfillment of
all the following conditions:  (a) the admission of such Shares to listing on all stock exchanges on which the class of stock is then listed; (b) the completion
of  any  registration  or  other  qualification  of  such  Shares  under  any  law  or  under  the  rulings  or  regulations  of  the  United  States  Securities  and  Exchange
Commission or any other governmental regulatory body, whether in the United States or elsewhere, which the Company shall, in its absolute discretion,
deem necessary or advisable; (c) the obtaining of any approval or other clearance from any governmental agency, which the Company shall, in its absolute
discretion, determine to be necessary or advisable; (d) the lapse of such reasonable period of time following the date of vesting of the RSUs as the Company
may establish from time to time for legal or administrative reasons; (e) the execution of the Appendix by the Employee and the acknowledgement of the
Appendix by the Employee’s attorney; and (f) compliance with the terms of the Agreement, including, without limitation the Appendix.

15.

Plan  Governs.    This  Agreement  is  subject  to  all  terms  and  provisions  of  the  Plan.    In  the  event  of  a  conflict  between  one  or  more
provisions of this Agreement and one or more provisions of the Plan, the provisions of the Plan shall govern except that the Governing Law and Venue
provisions of the Appendix shall govern rather than

Page 4

the  Choice  of  Law  and  Venue  provision  of  the  Plan  and  jurisdiction  and  venue  of  the  state  and  federal  courts  located  in  the  State  of  Delaware  shall  be
exclusive. 

16.
Agreement.

Captions.    Captions  provided  herein  are  for  convenience  only  and  are  not  to  serve  as  a  basis  for  interpretation  or  construction  of  this

17.

Agreement Severable.  In the event that any provision in this Agreement shall be held invalid or unenforceable, such provision shall be

severable from, and such invalidity or unenforceability shall not be construed to have any effect on, the remaining provisions of this Agreement.

18.

Modifications to the Agreement.  This Agreement (including any appendices attached hereto) constitutes the entire understanding of the
parties  on  the  subjects  covered.    The  Employee  expressly  warrants  that  he  or  she  is  not  executing  this  Agreement  in  reliance  on  any  promises,
representations, or inducements other than those contained herein. Subject to paragraph 21 below, modifications to this Agreement or the Plan can be made
only in an express written contract executed by a duly authorized officer of the Company.

19.

Governing  Law  and  Venue.    The  RSU  grant  and  the  provisions  of  this  Agreement  will  be  governed  by,  and  subject  to,  the  internal
substantive laws, but not the choice of law rules, of the State of Delaware.  For purposes of litigating any dispute that arises directly or indirectly from the
relationship of the parties evidenced by the grant or this Agreement, the parties hereby submit to and consent to the exclusive jurisdiction of the State of
Delaware and  agree  that  such  litigation  shall  be  conducted  only  in  the  courts  of  Delaware,  and  no  other  courts,  where  this  grant  is  made  and/or  to  be
performed. The Governing Law and Venue provision set forth in the Appendix shall govern.

20.

Appendix.  Notwithstanding any provisions in this Agreement, the RSU grant shall be subject to any additional terms and conditions set

forth in the Appendix and the Appendix is an integral part of this Agreement. 

21.

Imposition of Other Requirements.  The Company reserves the right to impose other requirements on the Employee’s participation in the
Plan, on the RSUs, and on any Shares acquired under the Plan, to the extent the Company determines it is necessary or advisable for legal or administrative
reasons, and to require the Employee to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

22.

Insider Trading Restrictions/Market Abuse Laws. By participating in the Plan, the Employee agrees to comply with the Company’s policy

on insider trading (to the extent that it is applicable to the Employee). The Employee acknowledges that, depending on his or her country or the broker’s
country, or the country in which the Shares are listed, the Employee may be subject to insider trading restrictions and/or market abuse laws in applicable
jurisdictions, which may affect his or her ability to accept, acquire, sell or attempt to sell, or otherwise dispose of the Shares, rights to Shares (e.g., the
RSUs) or rights linked to the value of Shares, during such times as the Employee is considered to have “inside information” regarding the Company (as
defined by the laws or regulations in applicable jurisdictions, including the United States and, if different, the Employee’s country). Local insider trading
laws and regulations may prohibit the cancellation or amendment of orders the Employee placed before possessing inside information. Furthermore, the
Employee may be prohibited from (i) disclosing insider information to any third party, including fellow employees or service providers (other than on a
“need-to-know” basis) and (ii) “tipping” third parties or causing them to otherwise buy or sell securities. Any restrictions under these laws or regulations are
separate from and in addition to any restrictions that may be imposed under any applicable Company insider trading policy. The Employee acknowledges
that it is the Employee’s responsibility to comply with any applicable restrictions, and the Employee should speak to his or her personal advisor on this
matter.

23.

Foreign  Asset/Account  Reporting  Requirements.  The  Employee  acknowledges  that  there  may  be  certain  foreign  asset  and/or  account
reporting requirements which may affect his or her ability to acquire or hold the Shares acquired under the Plan or cash received from participating in the
Plan (including from any dividends paid on the Shares) in a brokerage or bank account outside his or her country. The Employee may be required to report
such accounts, assets or transactions to the tax or other authorities in his or her country. The Employee also may be required to repatriate sale proceeds or
other funds received as a result of participating in the Plan to his or her country through a designated bank or broker within a certain time from receipt. The
Employee acknowledges that it is his or her responsibility to be compliant with such regulations.

24.

Waiver. The Employee acknowledges that a waiver by the Company of breach of any provision of this Agreement shall not operate or be

construed as a waiver of any other provision of this Agreement, or of any subsequent breach by the Employee or any other Participants.

EQUITY INCENTIVE PLAN

APPENDIX

Certain capitalized terms used but not defined in this Appendix have the meanings set forth in the Plan, the Notice of Grant and/or the Global Restricted
Stock Unit Agreement.

This Appendix includes additional terms and conditions that govern the RSUs to the Employee under the Plan

1.    Restrictive Covenants. In consideration for the award of RSUs with respect to ______ Shares as set forth in the Notice of Grant and this Agreement and
subject to the terms contained herein [and any other consideration], Employee hereby agrees to the restrictive covenants set forth in this Appendix.

A. The Company’s Legitimate Business Interests. Employee acknowledges and agrees that the Company has legitimate business interests in

protecting: (i) the Confidential Information and trade secrets to which the Company furnishes Employee and to which Employee has access to
during Employee’s employment with the Company; (ii) the Company’s substantial relationships with its customers, vendors, contractors,
consultants, and licensees; (iii) customer goodwill; and (iv) the Company’s relationship and goodwill with its employees. Employee further
acknowledges and agrees that due to the nature of Employee’s position with the Company, Employee would inevitably give a competitor an unfair
competitive advantage if Employee were to engage in Prohibited Activity as defined below or use certain Confidential Information, trade secrets
and goodwill entrusted to Employee by the Company for the benefit of a competitor. To protect these legitimate business interests of the Company,
Employee agrees to the provisions in this Appendix.

B. Noncompetition with Company’s Legitimate Business Interests.

Because of Company’s legitimate business interest as described in this Appendix and the good and valuable consideration offered to the Employee,
during the term of Employee’s employment and for [18 months][two years] to follow, to run consecutively, beginning on the last day of the
Employee’s employment with the Company, whether terminated for any reason or no reason, by the Employee or the Company, the Employee
agrees and covenants not to engage in Prohibited Activity.

“Prohibited Activity” is activity in which the Employee contributes the Employee’s knowledge, directly or indirectly, in whole or in part, as an
employee, employer, owner, operator, manager, advisor, consultant, contractor, agent, partner, director, stockholder, officer, volunteer, intern, or any
other similar capacity to [an entity competitive with the current or reasonably anticipated business of the Company, including, without limitation,
the laser industry or the photonics industry. Prohibited Activity also includes activity that may require or inevitably require disclosure of trade
secrets, proprietary information, or Confidential Information] [any of the following entities, their subsidiaries or other affiliates or successors: (i)
Lumentum Holdings Inc., (ii) MKS Instruments, Inc., (iii) Novanta Inc., (iv) IPG Photonics Corporation, (v) nLight, Inc., (vi) TRUMPF GmbH &
Co. KG, (vii) Wuhan Raycus Fiber Laser Technologies Co., Ltd., (viii) Pavillion Integration Corporation, (ix) Amplitude Laser Group, (x) Light
Conversion (a Lithuania company), (xi) Applied Materials, Inc., or (xii) KLA Corporation].

Nothing in this Agreement shall prohibit Employee from purchasing or owning less than five percent (5%) of the publicly traded securities of any
corporation, provided that such ownership represents a passive investment and that the Employee is not a controlling person of, or a member of a
group that controls, such corporation.

C. Non-Solicitation of Customers. During Employee’s employment with the Company and for a period of [18 months][2 years] following

Employee’s resignation, involuntary termination, or other separation from the Company, Employee will not, directly or indirectly: (i) cause or
encourage any of the Company’s Customers to refrain from purchasing the Company’s products or services; (ii) solicit, influence, or attempt to
influence any of the Company’s Customers to direct any purchase of products and/or services to any person or entity engaging in a business that is
the same, substantially similar, or a substitute for the Company’s business; or (iii) solicit, influence, or attempt to influence any of the Company’s
Customers to terminate their relationship or diminish the level of their business with the Company.

A-1

D. Non-Solicitation of Company Employees. During Employee’s employment with the Company and for a period of [18 months][2 years] following
Employee’s resignation, involuntary termination, or other separation from the Company, Employee will not, directly or indirectly, for Employee or
[any third party other than the Company] [any party with which the Employee has a relationship], solicit, induce, recruit, or encourage any of the
Company’s employees to leave their employment with the Company, or attempt to solicit, induce, recruit, or encourage any Company employees to
leave their employment with the Company[; provided, however, general advertising not specifically targeted at any employee of the Company shall
not violate this covenant and this covenant shall not apply with respect to any individual whose employment or other engagement with the
Company has been terminated for a period of 6 months or longer].

E. Non-Solicitation of Other Parties. During Employee’s employment with the Company and for a period of [18 months][2 years] following

Employee’s resignation, involuntary termination, or other separation from the Company, Employee will not, directly or indirectly, for Employee or
any third party other than the Company, solicit, induce, or encourage any vendor, consultant, collaborator, agent, contractor, or licensee of the
Company to cease or diminish its business relationship with the Company or engage in any activity that would cause them to cease or diminish
their business relationship with the Company.

F. Definitions.

i.

“Customers” are defined as persons who, during the last 18 months of Employee’s employment with the Company, have purchased or
used the Company’s products or services or have otherwise caused or referred others to purchase or use the Company’s products or
services. “Customers” include both a business or organization, as well as the individual persons who have some responsibility for making
or influencing the purchasing and use decisions of a business or organization with respect to the Company’s products or services.

ii. “Confidential Information” shall mean any and all technical and non-technical confidential knowledge, data or information related to the
business of the Company or to the business of any parent, subsidiary, affiliate, customer or vendor of the Company or any other party with
whom the Company agrees to hold information of such party in confidence, including without limitation: (a) trade secrets, inventions,
ideas, processes, computer source and object code, data, formulae, programs, other works of authorship, know-how, improvements,
discoveries, developments, designs and techniques; (b) information regarding products, services, plans for research and development,
marketing and business plans, budgets, financials statements, contracts, prices, suppliers and customers; (c) internal Company records
documenting the job performance, skills, evaluations, and compensation of the Company’s employees, contractors and any other service
providers of the Company; and (d) the existence of any business discussions, negotiations or agreements between the Company and any
third party. Without in any way limiting the foregoing, Confidential Information explicitly includes the Company’s list of its current and
potential customers. [Notwithstanding the foregoing, Confidential Information does not include any knowledge, data or information to the
extent the same has become publicly known and made generally available through no wrongful act of Employee or others.] Employee
understands that the Company has invested, and continues to invest substantial time, money, and specialized knowledge into developing its
Confidential Information by developing its sources, creating a customer base, generating customer and potential customer lists, and
training its employees. Employee understands and acknowledges that as a result of these efforts, the Company has created, and continues
to use and create Confidential Information. The Confidential Information provides the Company with a competitive advantage over others
in the marketplace.

G. Notice to Third Parties. Employee agrees that for so long as Employee is subject to the noncompetition and non-solicitation restrictions under this
Agreement, Employee shall inform any entity or person with whom Employee may seek to enter into a business relationship (whether as an owner,
Employee, independent contractor or otherwise) of Employee’s contractual obligations under this Agreement. Employee also understands and
agrees that the Company may, with or without prior notice to Employee and during or after Employee’s employment with the Company, notify third
parties of Employee’s agreements and obligations under this Agreement. Employee further agrees that, upon written request by the Company,
Employee will respond to the Company in writing regarding Employee’s compliance with all terms of this Appendix.

H. Defend Trade Secrets Act. Pursuant to the Defend Trade Secrets Act of 2016, 18 U.S.C. § 1833(b)(1), Employee acknowledges that Employee
shall not have criminal or civil liability under any federal or state trade secret law for the disclosure of a trade secret that (A) is made (i) in
confidence to a federal, state, or

A-2

local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected
violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. 

I. No Defense. Employee agrees and acknowledges that the existence of any counterclaim or dispute between Employee and the Company or any of

its officers, directors, or limited partners shall not constitute a defense to the enforcement of these covenants by the Company.

J. Tolling.  In  the  event  that  Employee  breaches  any  of  the  restrictive  covenants  as  set  forth  in  Paragraph  (B)  to  Paragraph  (E),  the  periods  of
noncompetition and non-solicitation described in Paragraph (B) through Paragraph (E) will be extended by an amount of additional time equal to
the lesser period of (i) two years or (ii) the amount of time between when such breach commenced and ending when the activities constituting such
breach ended.

K. Modification of Restrictive Covenants. If, in any judicial proceeding, a court refuses to enforce any of these separate covenants (or any part of a

covenant), then the unenforceable covenant (or part) will be eliminated from this Appendix to the extent necessary to permit the remaining separate
covenants (or portions) to be enforced. In the event that the provisions of this Appendix are deemed to exceed the time, geographic, or scope
limitations permitted by law, then the provisions will be reformed to the maximum time, geographic, or scope limitations permitted by law.

2.    Governing Law and Venue. This RSU, including in particular the terms of this Appendix, for all purposes, shall be governed by, construed and enforced
and the legality and validity of each term and condition shall be determined in accordance with internal, substantive laws of the State of Delaware without
regard to conflicts of law principles. Any action or proceeding by either Employee or the Company to enforce or avoid this Agreement, including, without
limitation, the terms of this Appendix or the RSU, or otherwise arising from or under the terms of this Agreement, shall be brought only in a state or federal
court located in the State of Delaware. Employee irrevocably submits to the sole and exclusive jurisdiction of the United States District Court for the District
of Delaware and the state courts of the State of Delaware for the purposes of any suit, action or other proceeding arising out of this Agreement including,
without limitation, this Appendix or the RSU or otherwise arising from or under the terms of this Agreement. Employee irrevocably and unconditionally
waives any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement including, without limitation, this Appendix or
the RSU or otherwise arising from or under the terms of this Agreement in the United States District Court for the District of Delaware or the state courts of
the State of Delaware, acknowledge the propriety of the venue there, and hereby irrevocably and unconditionally waive and agrees not to plead or claim in
any such court that any such action, suit or proceeding brought in such court has been brought in an inconvenient forum.

3.    Acknowledgement that Restrictive Covenants are Not a Condition of Employment and Representation by Counsel. Employee acknowledges that
Employee has carefully read this Agreement including, without limitation, the Appendix and consulted with legal counsel of Employee’s choosing regarding
its contents, has given careful consideration to the restraints imposed upon Employee by this Appendix and is in full accord as to their necessity for the
reasonable and proper protection of confidential and proprietary information of the Company now existing or to be developed in the future. Employee
acknowledges that Employee has consulted with counsel and is individually represented in negotiating the terms of this Agreement, which includes the
section designating the venue in which a controversy arising hereunder may be adjudicated and the choice of law to be applied hereto.

Employee understands, acknowledges and agrees that (i) Employee has no obligation to accept this RSU award and Employee’s decision to do so by signing
this Appendix is knowing and voluntary; and (ii) agreeing to the restrictive covenants contained in this Appendix is not a condition of employment and the
continuation of Employee’s employment will not depend on whether Employee agrees to the restrictive covenants. The agreement to the restrictive
covenants in this Appendix is in consideration of the RSUs set forth in the Notice of Grant and this Agreement [and any other consideration]. Employee
acknowledges and agrees that Employee was represented by counsel in connection with the negotiation of this Agreement, namely [attorney name],
including without limitation the specific negotiation of this Appendix, including its application to the RSUs with respect to governing law and venue.
Employee acknowledges that the Company is incorporated in Delaware. Employee acknowledges and agrees that the RSUs will be subject to restrictive
covenants, governing law, and dispute provisions set forth therein, to which Employee shall be bound in all respects. Employee further acknowledges and
agrees that pursuant to Section 925 of the California Labor Code, (i) Employee has waived the application of California law to this Agreement and the
RSUs, including without limitation, the restrictive covenants contained in this Appendix, and any proceeding related thereto, (ii) Employee has waived any
right to have any proceeding adjudicated in California, and (iii) Employee acknowledges and agrees that any proceeding shall not be deemed to be a
controversy arising in California.
