COMPANY OVERVIEW

BUSINESS BACKGROUND



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.

SIGNIFICANT EVENTS - MERGER

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 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 condensed 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,
                                       30

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 the proposed Merger is subject to customary closing
conditions, including, among others the expiration or termination of the
required waiting periods under the HSR Act and regulatory approvals in
applicable jurisdictions including Germany, China and South Korea. As previously
disclosed, II-VI and Coherent refiled their respective HSR Notification on May
2, 2022. The HSR Notification, which triggers a 30-day review period, was made
prior to the one-year expiration of II-VI's and Coherent's initial HSR
Notification filed last year. II-VI and Coherent continue cooperative
discussions with SAMR. Accordingly, other than the regulatory approval in China
and the United States, there are no other open regulatory closing conditions to
the proposed Merger. We anticipate that the closing of the Merger will occur
prior to June 30, 2022.

MARKET APPLICATIONS

Our products address a broad range of applications that we group into the following markets: Microelectronics, Precision Manufacturing, Instrumentation and Aerospace and Defense.



OUR STRATEGY

We strive to develop innovative and proprietary products and solutions that meet
the needs of our customers and that are based on our core expertise in lasers
and optical technologies. In pursuit of our strategy, we intend to:

•Execute our good to great transformation-Since our incorporation, we have
developed critical technology and have built this company into a multinational
corporation and leader in the photonics industry. We are engaged in a
multi-pronged and multi-year transformation focusing on all aspects of our
company. Namely, we are working to:

•Transform the operational efficiency of all our processes; •Reduce the complexity of our portfolio; •Focus our investments on growth opportunities; and •Enhance the focus and alignment with our customers



•Streamline our manufacturing structure and improve our cost structure-We are
focusing on optimizing the mix of products that we manufacture internally and
externally. We expect to further utilize vertical integration where our internal
manufacturing process is considered proprietary and seek to leverage external
sources when the capabilities and cost structure are well developed and on a
path towards commoditization.

•Focus on long-term improvement of adjusted EBITDA, in dollars and as a
percentage of net sales, and drive free cash flow and gross margin as a
percentage of 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 and gross
margin improvements include utilization of our manufacturing locations in Asia,
optimizing our supply chain and continued leveraging of our infrastructure. Our
focus on free cash flow is to generate cash over the long term as it is
essential to maintaining a healthy business and providing funds to help fuel
growth.

•Leverage our technology portfolio and application engineering to lead the
expansion of photonics into broader markets-We will continue to identify
opportunities in which our technology portfolio and application engineering can
be used to offer innovative solutions and gain access to new markets.

•Optimize our leadership position in existing markets-There are a number of
markets where we are at the forefront of technological development and product
deployment and from which we have derived a substantial portion of our revenues.
We plan to optimize our financial returns from these markets.

•Maintain and develop additional strong collaborative customer and industry
relationships-We believe that the Coherent brand name and reputation for product
quality, technical performance and customer satisfaction will help us
                                       31

to further develop our loyal customer base. We plan to maintain our current
customer relationships as well as develop new ones with customers who are
industry leaders and work together with these customers to design and develop
innovative product systems and solutions as they develop new technologies.

•Develop and acquire new technologies and market share-We will continue to
enhance our market position through our existing technologies and develop new
technologies through our internal research and development efforts, as well as
through the acquisition of additional complementary technologies, intellectual
property, manufacturing processes and product offerings.

•Focus on our core end markets-While we are organized around our two segments of OLS and ILS, we also take a holistic approach to aligning and driving our business to focus on our four core markets:



•Microelectronics (which captures the 3 sub-markets of Display, Semiconductor,
and Advanced Packaging & Interconnect);
•Precision Manufacturing;
•Instrumentation (which captures the 3 sub-markets of Bio-Instrumentation,
Therapeutics & Research); and
•Aerospace & Defense

APPLICATION OF CRITICAL ACCOUNTING POLICIES AND ESTIMATES



Our discussion and analysis of financial condition and results of operations are
based upon our condensed 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 condensed 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 condensed 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. See Item
7. "Management's Discussion and Analysis of Financial Condition and Results of
Operations" in our Annual Report on Form 10-K for our fiscal year ended
October 2, 2021.


KEY PERFORMANCE INDICATORS

Below is a summary of some of the quantitative performance indicators (as defined below) that are evaluated by management to assess our financial performance. Some of the indicators are non-GAAP measures and should not be considered as an alternative to any other measure for determining operating performance or liquidity that is calculated in accordance with generally accepted accounting principles.

Net Sales

Net sales include sales of lasers, laser systems, laser components, related
accessories and services. Net sales for the second quarter of fiscal 2022
increased 3.6% in our OLS segment and decreased 7.8% in our ILS segment from the
same quarter one year ago. Net sales for the first six months of fiscal 2022
increased 9.2% in our OLS segment and increased 5.6% in our ILS segment from the
same period one year ago. 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 in the second quarter of fiscal 2022 increased
to 47.9% from 45.2% in our OLS segment and increased to 32.8% from 27.7% in our
ILS segment as compared to the same quarter one year ago. Gross profit
percentage in the first six months of fiscal 2022 increased to 49.1% from 45.2%
in our OLS segment and increased to 33.2% from 25.6% in our ILS segment as
compared to the same period one year ago. For a description of the reasons for
changes in gross profit refer to the "Results of Operations" section below.

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 was 8.6% for the second quarter of fiscal 2022 and
the same quarter one year ago and decreased to 8.1% for the first six months of
fiscal 2022 from 8.6% for the same period one year ago. 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 condensed
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 the second quarter and first six months of 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 condensed
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 the second
quarter and first six months of 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 90 days for quarters. 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 the second
quarter of fiscal 2022 increased to 64 days from 60 days for the same quarter
one year ago. The increase was primarily due to the delay in collections of
certain receivables, which slipped to April 2022, partially due to the shutdown
of all businesses in Shanghai by the Chinese government at the end of the second
quarter of fiscal 2022. In addition, we experienced a higher concentration of
sales in the last month of the quarter ended April 2, 2022 compared to the last
month of the quarter ended April 3, 2021 as well as a higher concentration of
receivables with longer payment terms.

Annualized Second Quarter Inventory Turns



We calculate annualized second quarter inventory turns as the cost of sales
during the second quarter annualized and divided by net inventories at the end
of the second 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
inventory turns for the second quarter of fiscal 2022 decreased to 2.1 turns
from 2.4 turns for the same quarter a year ago primarily due to the favorable
impact of foreign exchange rates and higher inventory levels, primarily in our
ILS segment, resulting from higher purchases due to longer lead times and/or
anticipated supply constraints.

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 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.

SIGNIFICANT EVENTS

Russia/Ukraine Conflict

In February 2022, Russia invaded Ukraine, resulting in the United States,
Canada, the European Union ("EU") and other countries imposing economic
sanctions on Russia, some of which have been expanded to include Belarus. The
military conflict and the resulting sanctions have caused and are expected to
continue to cause significant disruptions in logistics, availability of
components and supplies used in the manufacture and services of our products and
global markets. The largest source of certain gases which are utilized in the
use and servicing of some of our products, including our largest excimer lasers,
has historically been located in Ukraine. We have accelerated purchases of this
gas from other limited sources outside of the conflict and, to date, have
avoided any material disruption to our business. Similarly, our end customers
for these products are largely located in geographies which have access to these
gases from local suppliers.

                                       35
--------------------------------------------------------------------------------
  Table of Content    s
Numerous logistic companies have meaningfully limited their capacity for
shipping goods as a result of the closing of certain air and land routes related
to the sanctions and conflict zones, which has resulted in significant increases
in inbound and outbound shipment costs.

As of the date hereof, it has been publicly reported that Russia has been
willing to leverage its supply of gasoline, oil and other fossil fuels in a
manner which could greatly limit the availability thereof to the EU, including
Germany. Relatedly, Germany and other countries in the EU have announced their
intention to meaningfully limit their importation of fuels which are supplied by
Russia at some point in the future.

We have managed through these situations and, to date, have not seen materially
negative consequences from the foregoing. A material reduction in our access to
critical gases, the disruption in the ability to source components and supplies
used in the manufacture, service or use of our products and the availability of
shipping and the increased costs therefor would likely negatively impact the
results of our operations. Additionally, the consequences of the foregoing or
other limitation on the availability of fuels to provide electricity in the EU
to businesses at the same current levels could have a material adverse effect on
our business, particularly with regards to our ability to manufacture and ship
products at our manufacturing locations in Germany.

We have historically had less than 1% of our revenues derived from customers in
Russia or Ukraine. Accordingly, compliance with the economic sanctions has not
had a material adverse impact on our results of operations through the period
reflected herein. As a result, based on available information to date, our
estimate of potential future impairments on our businesses in Russia or Ukraine
related to customer sales would not be material with respect to our consolidated
financial position. However, the conflict's continued impact of logistic and
supply chain challenges could result in a materially negative impact on our
results of operations in future periods.

Merger Agreement and related fees



See "Significant Events - Merger" above in this Item 2 for a description of the
Agreement and Plan of Merger we entered into on January 18, 2021, and the
Amended Lumentum Agreement we entered into on March 9, 2021 with Lumentum,
Lumentum Merger Sub I and Lumentum Merger Sub II, the termination of the Amended
Lumentum Agreement and the payment of a termination fee to Lumentum in the
second quarter of fiscal 2021, as well as the II-VI Merger Agreement we entered
into with II-VI and II-VI Merger Sub on March 25, 2021.

The termination fee, in addition to other costs related to the merger agreements is included in merger and acquisition costs in our condensed consolidated statements of operations.

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. The timing and extent of impact related to COVID-19 varies
by country and region.

Although we estimated that our sales for fiscal 2020 were negatively impacted by
the COVID-19 pandemic, we believe the impact on sales in fiscal 2021 and the
first two quarters of fiscal 2022 was immaterial. However, prolonged lockdowns
in Shanghai or any other major region in China may impact portions of our supply
chain and limit our ability to logistically fulfill customer commitments in
future quarters, which would negatively impact our sales and margins.

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. In fiscal 2021, and
continuing into fiscal 2022, 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 Delta and Omicron
variants, and the impact that it
                                       36
--------------------------------------------------------------------------------
  Table of Content    s
may have on future demand for our products and services, particularly given the
recent shutdown measures taken in certain countries in Europe and Asia,
particularly in Shanghai and other regions in China.

Currently, our major production facilities in Europe, 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 for
certain products. We also continue to face supply chain constraints primarily
related to electronic components and freight cargo capacity limitations,
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. As
noted above, these logistical challenges have been exacerbated by the
Russia/Ukraine conflict. 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. For example, we
have seen significant delays for the importation of goods into China as a result
of checks on containers for the presence of COVID-19. 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, at times, 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.

In the second quarter of fiscal 2022, product material shortages and the
lockdown of business and other activity in regions of China, including Shanghai,
caused an unfavorable revenue impact of approximately $19 million spread across
all markets, with our ILS segment impacted by $11 million and our OLS segment
impacted by $8 million.

Restructuring



In the fourth quarter of fiscal 2020, we began a restructuring program in our
ILS segment which included management reorganizations, the planned closure of
certain manufacturing sites, and the right-sizing of global sales, service,
order admin, marketing communication and certain administrative functions, among
others. In the first and second quarters of fiscal 2022, we incurred benefits of
$0.0 million and $2.3 million, respectively, primarily related to a gain from
the sale of assets and other cost reimbursements partially offset by estimated
severance, which is primarily recorded in selling, general and administrative
expenses. In the first and second quarters of fiscal 2021, we incurred costs of
$5.4 million and $3.6 million, respectively, primarily related to write-offs of
excess inventory and accruals for vendor commitments, which are recorded in cost
of sales, estimated severance and accelerated depreciation. The project is
substantially complete as of April 2, 2022.

NET SALES

As previously noted, we continue to monitor supply chain and logistic constraints and resultant cost increases related to COVID-19 and the Russian/Ukraine conflict. Although the Russian/Ukraine conflict did not materially impact our results in the second quarter of fiscal 2022, product material shortages and the lockdown of all business and other activity in regions of China, including Shanghai, caused an unfavorable revenue impact of approximately $19 million spread across all markets, with our ILS segment impacted by $11 million and our OLS segment impacted by $8 million.

Quarterly

Net sales for the second quarter of fiscal 2022 decreased by $3.8 million, or
1%, compared to the second quarter of fiscal 2021, with decreases in the
microelectronics and precision manufacturing markets partially offset by
increases in the aerospace and defense and instrumentation markets. We finished
fiscal 2021 with a positive book-to-bill ratio in all four end-markets, as well
as increased backlog levels compared to fiscal 2020 across all end-markets. We
also had a positive book-to-bill ratio in the first and second quarters of
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 increase of an aging population around the globe. Furthermore, we
believe that technology advances will result in increased laser-based defense
spending globally.

The decrease in the microelectronics market of $7.9 million, or 5%, was
primarily due to decreased shipments for flat panel display (primarily lower
revenues from systems) and advanced packaging applications partially offset by
higher shipments for semiconductor applications. 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 received
new orders for these products in both fiscal 2021 and the first two quarters of
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 strong demand
for semiconductor applications, somewhat tempered by constraints in the supply
chain for semiconductor chips. 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.

The decrease in the precision manufacturing market of $3.0 million, or 3%, was
due to lower sales in machine tools and automotive applications partially offset
by higher sales in medical and materials processing applications. The Purchasing
Managers Index ("PMI") is a measure of the prevailing economic trends in
manufacturing, and often correlates to materials processing sales. In the second
quarter of fiscal 2022 compared to the prior quarter, decreases in the
manufacturing PMI for China and Europe were partially offset by increases in the
U.S. Supply chain constraints continued in all regions due to both the shutdowns
in China and the Russian invasion of Ukraine. 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 orders continued to be
strong in the first two quarters of fiscal 2022 after record orders in fiscal
2021, particularly in the U.S.

The increase in the instrumentation market of $1.9 million, or 2%, was due
primarily to higher shipments for biomedical instrumentation applications
partially offset by lower 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 scientific and government program applications to continue to fluctuate from
quarter to quarter.

Sales in the aerospace and defense ("A&D") market increased $5.2 million, or
52%, primarily due to higher shipments in aerospace and defense applications. We
anticipate the A&D market, especially amplifiers for directed energy and
specialty optics for aerospace, to be a multi-year growth opportunity for us.

Year-to-date



Net sales for the first six months of fiscal 2022 increased by $54.7 million, or
8%, compared to the first six months of fiscal 2021, with significant increases
in the precision manufacturing and microelectronics markets and smaller
increases in the instrumentation and aerospace and defense markets.

The increase in the microelectronics market of $16.3 million, or 5.1%, was primarily due to increased shipments for semiconductor applications.



The increase in the precision manufacturing market of $20.1 million, or 10.7%,
was due to increased sales in medical, materials processing and consumer goods
applications.

The increase in the instrumentation market of $10.6 million, or 6.1%, was due primarily to higher shipments for biomedical instrumentation applications.

Sales in the aerospace and defense market increased $7.7 million, or 37.5%, primarily due to higher shipments in aerospace and defense applications.

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 as
well as applications in aerospace and defense.

Table of Content s



The 4.0% increase in gross profit percentage during the second quarter of fiscal
2022 included a 0.6% favorable impact of lower restructuring costs, primarily
related to lower severance costs, lower write-offs of inventories and lower
accelerated depreciation due to our closure of certain manufacturing sites and
0.4% lower amortization of intangibles. Additionally, gross profit percentage
increased 3.0% compared to the second quarter of fiscal 2021 primarily due to
favorable product margins (4.7%) partially offset by higher other costs (1.0%)
and higher warranty costs (0.7%). Product margins were favorable in both OLS and
ILS due to the impact of favorable absorption of manufacturing costs from higher
sales volumes, higher capitalized variances, and the favorable impact of the
weaker Euro against the U.S. Dollar. Additionally, the favorable impact of
selective price increases for certain products and services and favorable mix in
both OLS and ILS favorably impacted product margins, which was partially offset
by increased pricing for electronic components due to global supply chain and
logistical constraints, and fuel and expedited order surcharges. Other costs,
excluding restructuring provisions, were higher primarily due to increased
freight costs resulting from shipping constraints and fuel surcharges in both
segments and higher inventory provisions in ILS. The higher warranty and
installation costs as a percentage of sales were due to increased warranty
events for fiber components and CO2 and global tools products in ILS and lower
tube salvage in OLS.

The 5.4% increase in gross profit percentage during the first six months of
fiscal 2022 included a 1.0% favorable impact of lower restructuring costs,
primarily related to lower severance costs due to our closure of certain
manufacturing sites and 0.4% lower amortization of intangibles. Additionally,
gross profit percentage increased 4.0% compared to the first quarter of fiscal
2021 primarily due to favorable product margins (4.8%) partially offset by
higher other costs (0.6%) and higher warranty costs (0.2%). Product margins were
favorable in both OLS and ILS due to the impact of favorable absorption of
manufacturing costs from higher sales volumes, higher capitalized variances, and
the favorable impact of the weaker Euro against the U.S. Dollar. Additionally,
the favorable impact of selective price increases for certain products and
services and favorable mix in both OLS and ILS, partially offset by increased
pricing for electronic components due to global supply chain and logistical
constraints, and fuel and expedited order surcharges, favorably impacted product
margins. Other costs, excluding restructuring provisions, were higher primarily
due to higher freight costs resulting from shipping constraints and fuel
surcharges in both segments. The higher warranty and installation costs as a
percentage of sales were due to increased warranty events in both ILS and OLS.

Our gross profit percentage has been and will continue to be affected by a
variety of factors including the impact of shipping 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, pricing by competitors or suppliers
(including the impact of increased pricing on some of our critical supplies due
to global supply chain and logistical constraints, and fuel and expedited order
surcharges), 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.

impact of selective price increases for certain products and services and
improved mix (both mix of product and service revenues) partially offset by
increased pricing for electronic components due to global supply chain and
logistical constraints, and fuel and expedited order surcharges. The favorable
product costs were partially offset by higher warranty and installation costs
(0.7%) due to lower tube salvage for flat panel display systems, higher other
costs (0.2%) primarily due to higher freight costs resulting from shipping
constraints and fuel surcharges and higher intangibles amortization (0.1%) as a
percentage of sales.

The 3.9% increase in gross profit percentage during the first six months of

Research and development

Quarterly

Research and development ("R&D") expenses decreased $0.3 million, or 1%, during
the second quarter of fiscal 2022 compared to the same quarter one year ago. The
decrease was primarily due to $1.0 million lower employee-related spending due
to lower variable compensation and lower severance costs partially offset by
headcount additions for certain projects as well as $0.6 million lower charges
for changes in deferred compensation plan liabilities. The decreases were
partially offset by $0.8 million incremental spending due to the acquisition of
EOT in April 2021, $0.3 million higher project spending with higher spending on
materials offset by the favorable impact of higher customer reimbursements and
$0.2 million higher stock-based compensation expense.

On a segment basis as compared to the prior year period, OLS R&D spending
increased $1.0 million primarily due to the acquisition of EOT, higher spending
on materials and higher employee-related spending partially offset by higher
customer reimbursements. ILS R&D spending decreased $0.9 million primarily due
to lower employee-related spending partially offset by higher customer
reimbursements. Corporate and other R&D spending decreased $0.5 million
primarily due to lower charges for changes in deferred compensation plan
liabilities partially offset by higher stock-based compensation expense.

Year-to-date



Research and development ("R&D") expenses increased $1.2 million, or 2.0%,
during the first six months of fiscal 2022 compared to the same period one year
ago. The increase was primarily due to $1.5 million incremental spending due to
the acquisition of EOT in April 2021, $0.5 million higher project spending with
higher spending on materials offset by the favorable impact of higher customer
reimbursements and $0.2 million higher stock-based compensation expense. The
increases were partially offset by $1.0 million lower charges for changes in
deferred compensation plan liabilities.

Selling, general and administrative

Quarterly



Selling, general and administrative ("SG&A") expenses decreased $6.1 million, or
8%, during the second quarter of fiscal 2022 compared to the same quarter one
year ago. The decrease was primarily due to $4.6 million lower employee-related
spending with lower variable compensation, lower severance costs, lower sales
commissions and the favorable impact of foreign exchange rates partially offset
by higher costs due to merit increases, higher employee benefits costs and
higher headcount. SG&A expenses also decreased due to $3.2 million lower charges
for changes in deferred compensation plan liabilities and $0.2 million lower
stock-based compensation expense. Partially offsetting the decreases, SG&A
expenses increased due to $1.3 million higher other variable spending including
higher consulting on special projects, higher spending on travel and higher
other discretionary spending partially offset by higher restructuring benefit
from the sale of assets. SG&A expenses also increased due to $0.6 million
incremental spending due to the acquisition of EOT in April 2021.

On a segment basis as compared to the prior year period, OLS SG&A expenses
increased $0.6 million primarily due to the acquisition of EOT and higher
variable spending on travel and other discretionary spending partially offset by
lower employee-related spending. ILS SG&A spending decreased $3.9 million
primarily due to lower variable spending including higher restructuring benefit
and lower employee-related spending. Corporate and other SG&A spending decreased
$2.8 million primarily due to lower charges for changes in deferred compensation
plan liabilities and lower stock-based compensation expense partially offset by
higher consulting fees.

Year-to-date

Selling, general and administrative ("SG&A") expenses increased $13.4 million,
or 9.1%, during the first six months of fiscal 2022 compared to the same period
one year ago. The increase was primarily due to $20.0 million higher stock-based
compensation expense primarily resulting from the acceleration of vesting of
restricted stock units for certain executives. SG&A expenses also increased due
to $2.5 million higher other variable spending including higher consulting on
special projects, higher spending on travel and higher other discretionary
spending partially offset by higher restructuring benefit from the sale of
assets. SG&A expenses also increased due to $1.0 million incremental spending
due to the acquisition of EOT in April 2021. Partially offsetting the increases,
SG&A expenses decreased due to $5.4 million lower charges for changes in
deferred compensation plan liabilities and $4.7 million lower employee-related
spending with lower variable compensation, the favorable impact of foreign
exchange rates, lower commissions and lower severance costs partially offset by
higher costs due to merit increases, higher employee benefits costs and higher
headcount.

On a segment basis as compared to the prior year period, OLS SG&A expenses
increased $3.3 million primarily due to the acquisition of EOT, higher variable
spending on travel and other discretionary spending and higher employee-related
spending. ILS SG&A spending decreased $4.4 million primarily due to lower
variable spending including higher restructuring benefit and lower
employee-related spending. Corporate and other SG&A spending increased $14.5
million primarily due to higher stock-based compensation expense and higher
consulting fees partially offset by lower charges for increases in deferred
compensation plan liabilities and lower employee-related spending.

Merger and acquisition costs

In the second quarter of fiscal 2022, we recorded $1.0 million in merger and
acquisition costs for legal and other consultants related to our merger
agreement with II-VI. In the first six months of fiscal 2022, we recorded $2.0
in merger and acquisition costs for legal and other consultants related to our
merger agreement with II-VI.

In the second quarter and first six months of fiscal 2021, we recorded
$232.0 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.
Amortization of intangible assets

Amortization of intangible assets decreased $0.0 million and $0.1 million,
respectively, in the three and six months ended April 2, 2022 compared to the
same periods last year. The decreases were primarily due to the favorable impact
of foreign exchange rates.

OTHER INCOME (EXPENSE) - NET

Other income (expense), net, changed by $3.2 million to an expense of $5.7
million in the second quarter of fiscal 2022 from an expense of $2.5 million in
the second quarter of fiscal 2021. The increase in net other expense was
primarily due to $4.3 million lower gains/higher losses, net of expenses, on our
deferred compensation plan assets partially offset by $0.7 million lower
interest expense due to the payoff of our line of credit in October 2021 and the
favorable impact of foreign exchange rates.

Other income (expense), net, decreased by $7.1 million to an expense of $11.9
million in the first six months of fiscal 2022 from an expense of $4.8 million
in the first six months of fiscal 2021. The decrease in net other expense was
primarily due to $6.9 million lower gains/higher losses, net of expenses, on our
deferred compensation plan assets and $1.5 million higher foreign exchange
losses partially offset by $1.1 million lower interest expense due to the payoff
of our line of credit in October 2021 and the favorable impact of foreign
exchange rates.

INCOME TAXES



Our effective tax rates on income before income taxes for the three and six
months ended April 2, 2022 of 31.3% and 25.0%, respectively, were higher than
the U.S. federal tax rate of 21% primarily due to the impact of income subject
to foreign tax rates that are higher than the U.S. tax rates, limitations on the
deductibility of compensation under Internal Revenue Code Section 162(m),
stock-based compensation not deductible for tax purposes and the deferred taxes
on foreign earnings not considered permanently reinvested. These amounts are
partially offset by the benefit of federal research and development tax credits,
the benefit of a foreign-derived intangible income deduction and our Singapore
tax exemption. Our effective tax rate for the six months ended April 2, 2022
also reflected the excess tax benefits from restricted stock unit vesting.

Our effective tax rates on loss before income taxes for the three and six months
ended April 3, 2021 of 20.4% and 14.1%, respectively, were lower than the U.S.
federal tax rate of 21.0% primarily due to the benefit of federal research and
development tax credits and our Singapore tax exemption, partially offset by the
establishment of valuation allowances for certain foreign deferred tax assets,
the impact of income subject to foreign tax rates that are higher than the U.S.
tax rates, the deferred taxes on foreign earnings not considered permanently
reinvested, stock-based compensation not deductible for tax purposes and
limitations on the deductibility of compensation under Internal Revenue Code
Section 162(m).


LIQUIDITY AND CAPITAL RESOURCES



At April 2, 2022, we had assets classified as cash and cash equivalents and
short-term investments, in an aggregate amount of $402.0 million, compared to
$456.5 million at October 2, 2021. In addition, at April 2, 2022, we had $8.5
million of restricted cash. At April 2, 2022, approximately $311.4 million of
our cash and securities was held in certain of our foreign subsidiaries and
branches, $274.9 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 foreign subsidiaries also loaned approximately $20 million
and $60 million of funds to Coherent, Inc. in February 2022 and April 2022,
respectively, in anticipated payment of certain acquisition-related fees and
expenses. 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 our
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 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 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 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 "Part I, Item 3. 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
condensed consolidated statements of cash flows and the notes to condensed
consolidated financial statements:

Net cash provided by operating activities increased by $107.1 million for the
first six months of fiscal 2022 compared to the same period one year ago. The
increase in cash provided by operating activities was primarily due to higher
net income including non-cash adjustments and higher cash flows from deferred
income taxes, partially offset by lower cash flows from accrued payroll,
inventories, accounts payable, income taxes 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 have paid or expect to pay in equal
installments in the first quarters of fiscal 2022 (paid) 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. 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.

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

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.



In the first six months of fiscal 2022, we made debt principal payments of $3.8
million, recorded interest expense on the Euro Term Loan of $5.9 million and
recorded $1.4 million amortization of debt issuance costs.

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



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 then terminated that facility on March 1,
2022. No cash was restricted under this facility as of April 2, 2022.

Additional sources of cash available to us were international currency lines of
credit and bank credit facilities totaling $13.8 million as of April 2, 2022, of
which $12.3 million was unused and available. These unsecured international
credit facilities were used in Europe during the first six months of fiscal
2022. As of April 2, 2022, we had utilized $1.5 million of the international
credit facilities as guarantees in Europe.

Our ratio of current assets to current liabilities increased to 3.3:1 at
April 2, 2022 compared to 3.1:1 at October 2, 2021. The increase in our ratio
was primarily due to lower other current liabilities, lower short-term
borrowings and higher inventories partially offset by lower cash and
cash-equivalents and higher income taxes payable. Our cash and cash equivalents
and working capital are as follows:

Contractual Obligations and Off-Balance Sheet Arrangements
We have no off-balance sheet arrangements as defined under Regulation S-K of the
Securities Act of 1933. Information regarding our contractual obligations is
provided in Item 7 "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and Item 8 "Notes to Consolidated Financial
