ANNUAL REPORT, PROXY STATEMENT & NOTICE OF ANNUAL MEETING

DEAR SHAREHOLDERS, 
CUSTOMERS & EMPLOYEES

This  has  been  both  a  record-setting  and  challenging  year  for 
Coherent.    In  fiscal  2018,  the  company  posted  all-time  highs  for 
revenue,  gross  margin  and  earnings  per  share,  but  saw  increasing 
headwinds  in  two  of  our  markets  develop  towards  the  end  of  the 
fiscal year.  We have built a very solid business in OLED (organic light 
emitting diodes) display manufacturing by providing critical process 
technology  that  enhances  clarity,  energy  efficiency,  brightness  and 
refresh  (i.e.,  frame)  rates.    We  delivered  a  record  number  of  tools 
during  fiscal  2018  to  both  well-established  and  aspiring  OLED 
manufacturers.  

Despite the expansion of manufacturing capacity, OLED technology 
has proven difficult to master.  Samsung Display continues to lead in 
OLED performance, reliability and unit volume.  Their total output is 
estimated  at  about  one-third  of  today’s  smartphone  market.    The 
other  two-thirds  of  the  market  appears  to  want  access  to  OLED 
displays,  but  at  costs  well-below  what  Samsung  is  rumored  to  be 
charging.  Other manufacturers need to crack the code on high-yield 
manufacturing  of  OLEDs  to  allow  the  technology  to  proliferate.  
interesting  dynamic.  
These  circumstances  have  created  an 
Samsung appears to be focusing on high value business rather than 
trading  volume  for  pricing.    Their  competitors,  meanwhile,  are 
investing  in  R&D  and  pilot  production,  but  holding  off  on  volume 
scaling until they have validated all critical metrics.  This has led to 
an  investment  gap  in  fiscal  2019,  leading  us  to  project  that  the 
display market (i.e., systems and service) will be down in fiscal 2019 
compared to fiscal 2018.  

Even  with  this  apparent  pause,  there  are  numerous  reasons  to 
remain  optimistic  about  OLED  technology.    When  this  technology 
first emerged, we had suggested that fab construction was the best 
investment indicator.  There are more than twenty OLED fabs either 
under  construction  or  in  the  planning  phase  between  now  and 
2023, which could drive meaningful equipment and service revenue 
for  manufacturing  systems  providers.    A  number  of  them  are 
scheduled  to  come  online  in  2020  and  provide  the  basis  for  an 
expected  sales  recovery  in  the  same  time  frame.    There  have  also 
been  a  number  of  announcements  around  new  products  beyond 
the traditional smartphone market including foldable smartphones, 

new  applications  receive  regulatory  approval  and  more  people  gain  access  to 

sponsored medical care.  

Our  aerospace  and  defense  business  posted  very  good  growth  and  is  poised  for 

continued success.  We have won a significant amount of business for very large optics 

used in ground and space-based telescopes, including the new thirty-meter telescope 

(TMT)  project  being  sponsored  by  an  international  consortium.    These  optics  are 

polished  at  our  facility  in  Richmond,  California  before  receiving  metallic  coatings  to 

protect  them  from  exposure.    The  leading  provider  of  these  coatings  is  Quantum 

Coatings.    We  entered  into  an  agreement  in  October  2018  to  acquire  certain  assets 

and  intellectual  property  from  Quantum  that  enables  us  to  be  vertically  integrated.  

This same technology is applied to the large optics used in our FPD business.  

One of the key benefits of record financial results is very strong cash flow.  We used 

part of the cash to fund various capital investments to grow the business and improve 

its  efficiency  for  the  long  term.    We  made  voluntary  prepayments  of  approximately 

€285 million on our outstanding debt during fiscal 2018 and 2017 that further reduced 

our leverage levels.  We also repurchased approximately $100 million in the company’s 

common stock and announced a new authorization to repurchase up to an additional 

$250  million  of  common  stock  through  the  end  of  calendar  2019.    We  believe  the 

combined  benefits  of  emerging  applications  across  multiple  markets,  an  anticipated 

display rebound in fiscal 2020, strategic M&A opportunities and a reduced share count 

will prove to be very attractive to shareholders. 

Thanks you for your continued interest and support,

tablets and laptops that exploit the flexibility of OLEDs.  Collectively, we believe these 

opportunities,  along  with  a  growing  service  business,  should  provide  attractive 

longer-term growth in the FPD market.

The  materials  processing  market  has  also  exhibited  a  broad  range  of  opportunities 

and challenges for the company during fiscal 2018.  Much of our attention has been 

focused on automotive, medical device and consumer electronics manufacturing.  We 

have  made  good  progress  with  Tier  1  automotive  suppliers  and  have  demonstrated 

enabling  capabilities  in  EV  (electric  vehicle)  battery  manufacturing.    If  our  early 

successes continue, we will participate in one of the most environmentally impactful 

and financially attractive applications in the photonics universe.  

Another  application  that  covers  the  aforementioned 

focus  areas 

is  additive 

manufacturing  (i.e.,  3D  printing).    The  technique  has  been  used  to  transform  plastic 

resin into three-dimensional structures for more than two decades.  It has also been 

applied to making metal parts from metal powder, but the cost and other factors have 

relegated its use to very high value parts, especially in the aerospace arena.  A number 

of companies are trying to change this paradigm including OR Laser, whose founders 

believed that being able to design for additive rather than subtractive manufacturing 

was one of the keys to unlocking the market.  They developed a tool that is very well 

suited for a teaching environment so that design and mechanical engineering students 

could develop the expertise on how to exploit 3D printed parts in the lightweighting of 

motor  vehicles,  the  fabrication  of  custom  medical  and  dental  devices  and  the 

reduction of production waste.  OR also developed a custom operating environment 

that  is  very  intuitive  and  simple  to  use.    The  combination  of  OR’s  philosophy  and  a 

compelling market opportunity led us to acquire OR in April 2018.  While it’s a small 

business today, we are optimistic about its long-term growth potential.

It’s not all smooth sailing in materials processing.  For almost two decades, China has 

accounted for much of the growth in laser-based materials processing, first as a global 

factory and then addressing a growing domestic market.  Recently imposed U.S. tariffs 

on  Chinese 

imports  and, 

to  a 

lesser  extent,  Chinese 

tariffs  on  certain 

U.S.-manufactured photonics products have disrupted the market.  Facing uncertain 

demand and the prospect of additional tariffs, Chinese manufacturers have reduced 

spending,  which  has  had  a  direct  impact  on  the  demand  for  certain  products  in  our 

portfolio.  When combined with softness in the display market, a muted outlook in the 

materials processing market has led us to forecast that our company-wide fiscal 2019 

revenue will be down between 8-12% compared to fiscal 2018.  The drop in demand 

may  also  be  partially  responsible  for  a  price  war  that  has  ignited  in  the  fiber  laser 

market  as  competitors  jockey  for  market  share.    We  will  continue  to  support  our 

customers in China as the trade situation works to some form of resolution, while also 

pivoting towards opportunities that are not exposed to tariffs.

We  had  a  record  year  in  instrumentation  and  components.    Our  solution  set  for 

bioinstrumentation,  microscopy  and  sequencing  remains  the  industry  standard  and 

we  are  evolving  it  to  deliver  higher  content  and  value  to  OEM  customers.    In  the 

medical space, demand for lasers used in aesthetics, ophthalmology and dental as well 

as treatment kits for surgical  procedures was brisk.  We believe this will continue as

marking, signing, dating and returning the proxy card as promptly as possible in the postage-prepaid envelope provided for that
purpose.

This year, we will be using the ‘‘Notice and Access’’ method of providing proxy materials to you via the Internet. Accordingly, our
stockholders who have not previously requested paper copies of the materials will receive a Notice Regarding the Availability of
Proxy  Materials  with  instructions  on  how  to  access  the  proxy  materials  via  the  Internet.  The  notice  includes  instructions  for
requesting a paper copy of the proxy materials if that is your preference. We believe this approach provides stockholders with
easy access to the materials and a convenient method of voting, while reducing the printing, distribution and environmental costs
of the proxy process.

Any stockholder of record attending the meeting may vote in person even if he or she has returned a proxy. Please note, however,
that if your shares are held of record by a broker, bank or other nominee and you wish to vote at the meeting, you must obtain a
proxy issued in your name from that record holder.

Santa Clara, California
January 14, 2019

Sincerely,

Important Notice Regarding the Availability of Proxy Materials for the Stockholder Meeting to Be Held on February 28, 2019

The proxy statement and annual report to stockholders are available at www.proxyvote.com.

PROXY STATEMENT

General Information About the Meeting

General
The Proxy is solicited on behalf of the Board of Directors (the ‘‘Board’’) of Coherent, Inc. (‘‘Coherent’’ or the ‘‘Company’’) for use at
the Annual Meeting of Stockholders (the ‘‘Annual Meeting’’ or ‘‘meeting’’) to be held at 8:00 a.m., local time, on February 28, 2019
at the Hyatt Regency Santa Clara, 5101 Great America Parkway, Santa Clara, California 95054, and at any adjournment(s)
thereof, for the purposes set forth herein and in the accompanying Notice of Annual Meeting of Stockholders. Our telephone
number is (408) 764-4000. These proxy solicitation materials were first mailed on or about January 14, 2019 to all stockholders
entitled to vote at the Annual Meeting.

Who May Vote at the Meeting?
You are entitled to vote at the Annual Meeting if our records
show that you held your shares as of the close of business on
our record date, December 31, 2018 (the ‘‘Record Date’’). On
the  Record  Date,  24,326,589  shares  of  our  common  stock,
$0.01 par value, were issued and outstanding.

What Does Each Share of Common
Stock I Own Represent?
On all matters, each share has one vote, unless, with respect
to  Proposal  One  regarding 
the  election  of  directors,
cumulative voting is in effect. See ‘‘Proposal One—Election of
Directors—Vote  Required’’  for  a  description  of  cumulative
voting rights with respect to the election of directors.

Why did I Receive a One-Page Notice
in the Mail Regarding the Internet
Availability of Proxy Materials Instead
of a Full Set of Proxy Materials?

In accordance with the Securities and Exchange Commission
(‘‘SEC’’)  rules,  we  are  furnishing  proxy  materials  to  our
stockholders  primarily  via  the  Internet,  instead  of  mailing
printed  copies  of  those  materials  to  each  stockholder.  On
January 14, 2019, we commenced mailing a Notice Regarding
the Availability of Proxy Materials to our stockholders (other
than those who had previously requested electronic or paper

delivery) containing instructions on how to access our proxy
materials,  including  this  proxy  statement  and  our  annual
report.  The  Notice  Regarding  the  Availability  of  Proxy
Materials  sets  forth  instructions  on  how  to  vote  over  the
Internet and also how to request paper copies if that is your
preference.

This  process  is  designed  to  provide  stockholders  with  easy
access  to  our  proxy  materials,  while  reducing  the  printing,
distribution  and  environmental  costs  of  the  proxy  process.
However,  if  you  would  prefer  to  receive  printed  proxy
materials, please follow the instructions included in the Notice
Regarding the Availability of Proxy Materials.

How Does a Stockholder Vote?
Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy to ensure your vote is counted. If you are
entitled to vote, you may do so as follows:

• Through the Internet: Follow the instructions in the Notice Regarding the Availability of Proxy Materials or otherwise go to

www.proxyvote.com to complete an electronic proxy card.

• Using the Telephone: Dial toll-free 1-800-690-6903 using a touch-tone phone and follow the recorded instructions. You will
be asked to provide the control number from your Notice Regarding the Availability of Proxy Materials or your proxy card.

General Information

• Through your broker: If your shares are held through a broker, bank or other nominee (commonly referred to as held in
‘‘street name’’), you will receive instructions from them that you must follow to have your shares voted. If you want to vote in
person, you will need to obtain a legal proxy from your broker, bank or other nominee and bring it to the meeting.

• In person: Attend the Annual Meeting and, if you request, we will give you a ballot at the time of voting. If you have previously
submitted a proxy card, you must notify us at the Annual Meeting that you intend to cancel your prior proxy and vote by ballot at
the meeting.

• Returning a Proxy Card: If you have requested printed proxy materials, simply complete, sign and date the proxy card and
return it promptly in the envelope provided. If your signed proxy card is received before the Annual Meeting, the designated
proxies will vote your shares as you direct.

For  telephone  or  Internet  use,  your  vote  must  be  received  by  11:59  p.m.,  Eastern  time,  on  February  27,  2019  to  be
counted.

If you return a signed and dated proxy card without marking any voting directions, your shares will be voted ‘‘for’’ the election of
all eight nominees for director set forth in this proxy statement and ‘‘for’’ Proposals Two and Three.

Matters to be Presented at the Meeting
We are not aware of any matters to be presented at the meeting other than those described in this proxy statement. If any other
matter is properly presented at the Annual Meeting, your proxy holders (one of the individuals named on your proxy card) will vote
your shares in their discretion. The cost of this solicitation will be borne by us. We may reimburse brokerage firms and other
persons representing beneficial owners of shares for their expenses in forwarding solicitation material to such beneficial owners.
In addition, proxies may be solicited by certain of our directors, officers and regular employees, without additional compensation,
personally or by telephone, e-mail or facsimile.

Revoking Your Proxy
If you hold your shares in street name, you must follow the instructions of your broker, bank or other nominee to revoke your voting
instructions. If you are a holder of record and wish to revoke your proxy instructions, you must (i) advise the Corporate Secretary
in writing at our principal executive offices at 5100 Patrick Henry Dr., Santa Clara, California 95054 before the proxies vote your
shares at the meeting, (ii) timely deliver later-dated proxy instructions or (iii) attend the meeting and vote your shares in person.

Attendance at the Annual Meeting

All stockholders of record as of the Record Date may attend
the  Annual  Meeting.  Please  note  that  cameras,  recording
devices and similar electronic devices will not be permitted at
the Annual Meeting. No items will be allowed into the Annual
Meeting  that  might  pose  a  concern  for  the  safety  of  those
attending. Additionally, to attend the meeting you will need to
bring identification and proof sufficient to us that you were a
stockholder of record as of the Record Date or that you are a

duly authorized representative of a stockholder of record as of
the Record Date. The meeting will be subject to certain rules of
conduct,  which  will  be  described  in  a  guidelines  and
procedures document that will be distributed to attendees at
the  meeting.  For  directions  to  attend  the  Annual  Meeting  or
other  questions,  please  contact 
Investor  Relations  by
telephone  at  (408)  764-4110  no  later  than  noon  (California
time) on February 27, 2019.

Quorum; Abstentions; Broker
Non-Votes

Our bylaws provide that stockholders holding a majority of the
shares of common stock issued and outstanding and entitled
to vote on the Record Date constitute a quorum at meetings of
stockholders.  Votes  will  be  counted  by  the  inspector  of
election appointed for the Annual Meeting, who will separately
count  ‘‘For’’  and  ‘‘Against’’  votes,  abstentions  and  broker
non-votes.

A ‘‘broker non-vote’’ occurs when a nominee holding shares
for  a  beneficial  owner  does  not  vote  because  the  nominee
does not have discretionary voting power with respect to the
proposal and has not received instructions with respect to the

Deadline for Receipt of Stockholder
Proposals or Nominations; Proxy
Access

In order to submit stockholder proposals for inclusion in our
proxy  statement  pursuant  to  Rule  14a-8  of  the  Securities
Exchange Act of 1934, as amended (‘‘SEC Rule 14a-8’’) for
the annual meeting to be held in fiscal 2020, written materials
must be received by the Corporate Secretary at our principal
office in Santa Clara, California no later than September 16,
2019. Stockholder proposals must otherwise comply with the
requirements of SEC Rule 14a-8.

Proposals  must  be  addressed  to:  Bret  DiMarco,  Corporate
Secretary,  Coherent,  Inc.,  5100  Patrick  Henry  Dr.,  Santa
Clara,  California  95054.  Simply  submitting  a  proposal  does
not guarantee its inclusion.

Section  2.16  of  the  Company’s  bylaws  also  establishes  an
advance notice procedure with respect to director nominations
and stockholder proposals that are not submitted for inclusion
in the proxy statement, but that a stockholder instead wishes
to present directly from the floor at any annual meeting. To be
properly brought before the annual meeting to be held in fiscal
2020, a notice of the nomination or the matter the stockholder
wishes  to  present  at  the  meeting  must  be  delivered  to  the
Corporate  Secretary  (see  above),  no  later  than  the  close  of
business  on  the  45th  day  (November  30,  2019),  nor  earlier
than  the  75th  day  (October  31,  2019),  prior  to  the  one  year
anniversary of the date these proxy materials were first mailed
by us, unless the annual meeting of stockholders is held prior
to January 29, 2020 or after April 28, 2020, in which case, the
proposal must be received by us not earlier than the close of

account  in  determining  the  outcome  of  any  proposal.
Abstentions will not be taken into account in determining the
outcome of the election of directors. However, abstentions are
deemed to be votes cast with respect to Proposals Two and

If a stockholder who has notified us of his or her intention to
present a proposal at an annual meeting does not appear to
present  his  or  her  proposal  at  such  meeting,  we  need  not

present 
chairperson  of  the  annual  meeting  has  the  final  discretion
whether  or  not  to  allow  any  matter  to  be  considered  at  the
meeting which did not timely comply with all applicable notice
requirements.

consideration by the Governance and Nominating Committee

proxy statement.

In  addition,  our  bylaws  provide 
that,  under  certain
circumstances,  a  stockholder  or  group  of  stockholders  may
include  director  candidates  that  they  have  nominated  in  our
proxy  statement.  These  proxy  access  provisions  permit  a
stockholder,  or  a  group  of  up  to  20  stockholders,  who  have
owned  3%  or  more  of  our  outstanding  common  stock
continuously  for  at  least  three  years  to  submit  director
nominees  (for  up  to  20%  of  the  number  of  directors  then  in
office)  for  inclusion  in  our  proxy  materials,  as  long  as  the
timely  written  notice  of  such
stockholder(s)  provide 
nomination and the stockholder(s) and nominee(s) satisfy the
requirements  specified  in  our  bylaws.  Notice  of  director
nominees for our 2020 annual meeting of stockholders must

include the information required under our bylaws and must be

offices between the close of business on August 17, 2019 and
the close of business on September 16, 2019, unless the date
of the annual meeting to be held in fiscal 2020 is more than
30 days before or more than 60 days after the anniversary of

delivered not earlier than the 90th day prior to the date of the
annual meeting to be held in fiscal 2020 and not later than the
close of business on the later of (i) the 60th day prior to the

10th day following the day on which public announcement of
the  date  of  such  meeting  is  first  made.  For  additional

provisions, please refer to the Company’s bylaws.

regarding 

Eliminating Duplicative Proxy
Materials

To reduce the expense of delivering duplicate voting materials
to  our  stockholders  who  may  hold  shares  of  Coherent
common  stock  in  more  than  one  stock  account,  we  are
delivering only one Notice Regarding the Availability of Proxy
Materials and/or set of the other proxy solicitation materials,
as applicable, to certain stockholders who share an address,
unless otherwise requested. A separate proxy card is included
in  the  voting  materials  (either  electronically  or  by  mail,  as
applicable) for each of these stockholders.

We  will  promptly  deliver,  upon  written  or  oral  request,  a
separate copy of the annual report or this proxy statement to a
stockholder at a shared address to which a single copy of the
documents was delivered. To obtain an additional copy, you
may  write  us  at  5100  Patrick  Henry  Drive,  Santa  Clara,

such  stockholder  from  the  householding  program  within
30 days of receipt of such written notice, after which each such
stockholder  will  receive  an  individual  copy  of  our  proxy
materials.

Spotlight on Governance

Our historical business results have been complemented by
an  approach  to  corporate  governance  that  has  consistently
been recognized for best practices, including:

*

*

*

Annual Board elections with no classified Board;

Stockholders may act by written consent;

Independent Board Chair;

* Majority voting for members of the Board in uncontested

*

*

*

*

*

*

*

elections;

‘‘Proxy access’’ bylaw provision;

No ‘‘blank check’’ preferred stock;

Super majority of independent directors on the Board;

Executive  compensation  heavily  weighted 
performance;

towards

No  super  majority  stockholder  approval  for  mergers  or
other business combinations in our bylaws or charter;

Age-based Board tenure/refreshment guidelines; and

Board,  CEO  and  executive  officer  stock  ownership
requirements.

Importantly,  the  Board  has  implemented  our  governance
approach  with  the  full  support  and  recommendation  of  senior
management.  These  governance  practices  do  not  result  from
any shareholder proposals related to them. Rather, they reflect
the  commitment  of  the  Board  and  management  to  maintain
common sense and industry-leading governance practices and
financial
to  go  along  with  our  historical  strong 
policies 
performance.  Our  Board’s  independent  director  composition
consists of 29% female directors and over 40% diverse directors.
Our Board is 88% independent, with only our CEO serving as an
inside director.

In addition to a diverse background of experiences, the Board
believes  it  is  extremely  important  to  have  a  balance  of
independent service on the Board, with a mix of new (0-5 years),
mid-term  (5-10  years)  and  long-term  (more  than  10  years)
tenures  participating.  Our  financial  performance  over  the  past
decade is proof that our shareholders have benefited from having
a  Board  with  a  strong  history  of  refreshment  and  including
various tenured members. In general the Board seeks to have
the  greatest  weight  towards  the  new  and  mid-term  categories
(which  may  vary  from  time  to  time),  which  is  reflected  in  the
current  composition  of  our  independent  directors  following  the
annual meeting:

New Members (five years or less):
Mid-Term Members (five to ten years):
Long-Term Members (more than ten years):

Coherent has also undertaken several less publicized ‘‘green’’
initiatives, such as the installation of over 1200 solar panels on
our corporate headquarters building. This array develops over
400kW  of  energy  per  hour  and  approximately  625,000  kW
hours annually, which reduces greenhouse gas emissions by
approximately 460 tons per year. This installation also allowed
us  to  place  eight  electric  vehicle  charging  stations  that  our
employees  can  use

significantly  reduced  the  amount  of  power  and  consumable
materials needed to operate our products.

which is the equivalent of 187,250 meals for those in need in
Silicon  Valley.  We  are  proud  to  have  been  the  largest
corporate  donor  during  their  annual  spring  donation  drive.
While  much  has  been  debated  about  requiring  public
companies to disclose their ‘‘political spending,’’ we voluntarily
disclose that we had no such corporate spending in 2018.

Our Board, management and employees take great pride in
our financial performance, governance, stockholder relations
and global corporate citizenship.

PROPOSAL ONE
ELECTION OF
DIRECTORS
Nominees

Eight (8) members of the Board are to be elected at the Annual
Meeting,  seven  (7)  of  whom  are  standing  for  re-election.
Mr. McMullen, who was recommended to the Governance and
Nominating  Committee  by  the  search  firm  retained  by  the
committee,  joined  the  Board  effective  as  of  September  28,
2018  (prior  to  the  end  of  fiscal  2018)  and  is  standing  for
election  for  the  first  time  at  the  Annual  Meeting.  Unless
otherwise  instructed,  the  proxy  holders  will  vote  the  proxies
received  by  them  for  the  nominees  named  below.  Each
nominee has consented to be named a nominee in the proxy
statement and to continue to serve as a director, if elected. If
any  nominee  becomes  unable  or  declines  to  serve  as  a
director, if additional persons are nominated at the meeting or
if  stockholders  are  entitled  to  cumulate  votes,  the  proxy
holders intend to vote all proxies received by them in such a
manner (in accordance with cumulative voting) as will ensure
the  election  of  as  many  of  the  nominees  listed  below  as
possible,  and  the  specific  nominees  to  be  voted  for  will  be
determined by the proxy holders.

We  are  not  aware  of  any  reason  that  any  nominee  will  be
unable or will decline to serve as a director. The term of office
of each person elected as a director will continue until our next
annual meeting of stockholders or until a successor has been
elected and qualified or until his or her earlier resignation or
removal.  There  are  no  arrangements  or  understandings
between any director or executive officer and any other person
pursuant  to  which  he  or  she  is  or  was  to  be  selected  as  a
director or officer.

The  names  of  the  nominees,  all  of  whom  are  currently
directors  standing  for  re-election,  and  certain  information
about them are set forth below. All of the nominees have been
unanimously  recommended  for  nomination  by  the  Board
acting on the unanimous recommendation of the Governance
and  Nominating  Committee  of  the  Board.  The  committee
consists solely of independent members of the Board. There
are  no  family  relationships  among  directors  or  executive
officers of Coherent.

Retiring Director
On September 25, 2018, L. William Krause informed the Board that, in accordance with the mandatory retirement age guideline in
our Governance Guidelines, he intended to retire from our Board at the end of his current term and not stand for reelection at our
annual meeting. We are grateful for Mr. Krause’s distinguished service and instrumental guiding voice as a member of the Board
since 2009.

The Company’s bylaws provide that the number of directors on the Board will be between five (5) and nine (9), and that the Board
has the authority to set the number from time to time. In light of Mr. Krause’s retirement, the Board has resolved that the number of
directors on the Board will be decreased from nine (9) to eight (8) effective at our annual meeting.

Director Independence
The Board has determined that, with the exception of Mr. Ambroseo, all of its current members and all of the nominees for director
are ‘‘independent directors’’ as that term is defined in the listing rules of the Nasdaq Stock Market.

Board Meetings and Committees

The Board held a total of five (5) formal meetings and acted two
(2)  times  by  unanimous  written  consent  during  fiscal  2018.
Additionally,  from  time  to  time  between  formal  meetings,
members of the Board participate in update or status telephone
calls  and  briefings,  which  are  not  included  in  these  totals.
During fiscal 2018, the Board had three standing committees:
the Audit Committee; the Compensation and H.R. Committee;
and the Governance and Nominating Committee. From time to
time, the Board may create, and has in the past created, limited
ad  hoc  committees,  service  on  which  does  not  provide
additional compensation. Each of our directors attended at least
75% of the meetings of the Board and the committees on which
he or she served during fiscal 2018.

Audit Committee
The  Audit  Committee  consists  of  directors  James  (Chair),
Fletcher,  Rogerson  and  Skaggs.  The  Audit  Committee  held
twelve  (12)  meetings  during  fiscal  2018.  The  Board  has
determined  that  directors  James,  Rogerson  and  Skaggs  are
‘‘audit committee financial experts’’ as that term is defined in the
rules of the SEC. Among other things, the Audit Committee has
the  sole  authority 
for  appointing  and  supervising  our
independent registered public accounting firm and is primarily

12

responsible  for  approving  the  services  performed  by  our
independent registered public accounting firm and for reviewing
and  evaluating  our  accounting  principles  and  our  system  of
internal accounting controls.

Compensation and H.R. Committee
The Compensation and H.R. Committee consists of directors
Vij (Chair), Flatley, Krause and McMullen. The Compensation
and H.R. Committee held eight (8) meetings during fiscal 2018.
Mr. McMullen was appointed to the committee on December 6,
2018,  and  Mr.  Krause  will  no  longer  serve  on  the  committee
upon his retirement from the Board. As noted above, all of the
members  of  the  Compensation  and  H.R.  Committee  are
‘‘independent’’ as defined under the listing rules of the Nasdaq
Stock Market. The Compensation and H.R. Committee, among
reviews  and  approves  our  executive
other 
compensation policies and programs, and makes equity grants
to  our  employees,  including  officers,  pursuant  to  our  equity
plan.  In  fiscal  2018,  this  committee  had  the  sole  authority
delegated to it by the Board to make employee equity grants,
which are done at a meeting rather than by written consent. On
September  27,  2018,  however, 
the
recommendation  of  the  Compensation  and  H.R.  Committee,

the  Board,  at 

things, 

designated an Equity Committee with authority to make grants
of restricted stock units, within guidelines recommended by the
Compensation  and  H.R.  Committee,  to  individuals  who  are
employees serving at a level below that of vice president. The
Equity Committee is composed of our CEO, in his capacity as a
member of the Board. The Equity Committee will report to the
Compensation  and  H.R.  Committee  periodically  and  upon
request of the Compensation and H.R. Committee. The Equity
Committee’s designated authority is first effective for fiscal 2019
and is concurrent with and does not supersede the authority of
the  Compensation  and  H.R.  Committee.  For  additional

Governance and Nominating Committee
The  Governance  and  Nominating  Committee  consists  of
directors Rogerson (Chair), Flatley, James and Skaggs. During

Proposal One Election of Directors

fiscal 2018, Mr. Krause served as a member of the Governance
and  Nominating  Committee  through  March  1,  2018,  at  which
point  Mr.  Flatley  and  Mr.  Skaggs  were  appointed  to  the
committee. The Governance and Nominating Committee held
eight  (8)  meetings  during  fiscal  2018.  The  Governance  and
Nominating Committee, among other things, assists the Board
by  making  recommendations 
the  Board  on  matters
concerning  director  nominations  and  elections,  board
committees  and  corporate  governance,  allocation  of  risk
oversight  amongst 
its  committees  and
the  Board  and 
compensation  for  directors.  For  fiscal  2018,  the  committee
retained an independent compensation consultant to advise it
on compensation for service on the Board.

Attendance at Annual Meeting of Stockholders by the Members of the Board of
Directors
All directors are encouraged, but not required, to attend our annual meeting of stockholders. At our annual meeting held on March 1,
2018, all then-current members of the Board attended in person.

Process for Stockholders to
Recommend Candidates for Election
to the Board of Directors

The  Governance  and  Nominating  Committee  will  consider
nominees  properly 
recommended  by  stockholders.  A
stockholder that desires to recommend a candidate for election
to the Board must direct the recommendation in writing to us at
our principal executive offices (Attention: Corporate Secretary)
and  must  include  the  candidate’s  name,  age,  home  and
business  contact 
information,  principal  occupation  or
employment, the number of shares beneficially owned by the
nominee  and  the  stockholder  making  the  recommendation,
whether any hedging transactions have been entered into by
the nominee or on his or her behalf, information regarding any
arrangements or understandings between the nominee and the
stockholder  nominating  the  nominee  or  any  other  persons
relating to the nomination, a written statement by the nominee
acknowledging  that  the  nominee  will  owe  a  fiduciary  duty  to
Coherent  if  elected,  a  written  statement  of  the  nominee  that
such nominee, if elected, intends to tender, promptly following

such  nominee’s  election  or  re-election,  an 
irrevocable
resignation effective upon such nominee’s failure to receive the
required vote for re-election at the next meeting at which such
nominee would face re-election and upon acceptance of such
resignation  by  the  Board  in  accordance  with  Coherent’s
guidelines or policies, and any other information required to be
disclosed about the nominee if proxies were to be solicited to
elect the nominee as a director.

For  a  stockholder  recommendation  to  be  considered  by  the
Governance  and  Nominating  Committee  as  a  potential
candidate at a meeting of stockholders, nominations must be
received  on  or  before  the  deadline  for  receipt  of  stockholder
proposals for such meeting. In the event a stockholder decides
to nominate a candidate for director and solicits proxies for such
candidate, the stockholder will need to follow the rules set forth
by the SEC and in our bylaws. See ‘‘General Information About
the Meeting—Deadline for Receipt of Stockholder Proposals.’’

Governance  and  Nominating  Committee  considers  each
individual candidate in the context of the current perceived
needs of the Board as a whole. While the Governance and
Nominating  Committee  has  not  established  specific
the
minimum  qualifications 
committee  believes  that  candidates  and  nominees  must
reflect  a  Board  that  is  comprised  of  directors  who  (i)  are
predominantly  independent,  (ii)  are  of  high  integrity,
(iii)  have  qualifications  that  will  increase  the  overall
effectiveness of the Board, and (iv) meet other requirements

and Nominating Committee has the authority to retain and
terminate any third party search firm that is used to identify
director  candidates  and  has  the  authority  to  approve  the
fees and retention terms of any search firm; and

• after such review and consideration, the Governance and
Nominating  Committee  recommends  the  slate  of  director
nominees to the full Board for its approval.

The Governance and Nominating Committee will endeavor to
notify, or cause to be notified, all director candidates, including
those  recommended  by  a  stockholder,  of  its  decision  as  to
whether to nominate such individual for election to the Board.

to  recommend 

Our  corporate  governance  guidelines  require  that  upon  a
member  of  the  Board  turning  72  years  old,  he  or  she  shall
submit  a  conditional  resignation  to  the  Governance  and
Nominating  Committee  effective  upon  the  next  annual
meeting  of  stockholders.  The  committee  then  determines
whether 
the  Board  accept  such
that 
resignation. Ms. James has so notified the committee, which
determined  that  it  was  not  in  the  best  interest  of  the
Company’s  stockholders  to  accept  her  resignation  and  has
included  Ms.  James  in  the  slate  for  this  year’s  election  of
directors.  As  described  in  ‘‘—Retiring  Directors’’  above,  on
September 25, 2018, Mr. Krause informed the Board that, in
accordance with the mandatory retirement age guideline, he
intends to retire from the Board at the end of his current term
and will not stand for reelection at the Annual Meeting.

Proposal One Election of Directors

The  Governance  and  Nominating  Committee’s  criteria  and
process  for  evaluating  and  identifying  the  candidates  that  it
approves as director nominees are as follows:

• the  Governance  and  Nominating  Committee  regularly
reviews the current composition and size of the Board;

• the  Governance  and  Nominating  Committee  reviews  the
qualifications  of  any  candidates  who  have  been  properly
recommended  by  a  stockholder,  as  well  as 
those
candidates  who  have  been  identified  by  management,
individual members of the Board or, if the Governance and
Nominating  Committee  determines,  a  search  firm.  Such
review  may, 
the  Governance  and  Nominating
review  solely  of
Committee’s  discretion, 
information  provided  to  the  Governance  and  Nominating
Committee  or  may  also  include  discussions  with  persons
familiar with the candidate, an interview with the candidate
or other actions that the committee deems proper;

include  a 

in 

• the Governance and Nominating Committee evaluates the
performance  of  the  Board  as  a  whole  and  evaluates  the
qualifications of individual members of the Board eligible for
re-election at the annual meeting of stockholders;

• the Governance and Nominating Committee considers the
suitability of each candidate, including the current members
of the Board, in light of the current size and composition of
the Board. Except as may be required by rules promulgated
by  the  Nasdaq  Stock  Market  or  the  SEC,  it  is  the  current
belief  of  the  Governance  and  Nominating  Committee  that
there are no specific, minimum qualifications that must be
met by any candidate for the Board, nor are there specific
qualities or skills that are necessary for one or more of the
members  of  the  Board  to  possess.  In  evaluating  the
qualifications  of  the  candidates,  the  Governance  and
Nominating Committee considers many factors, including,
issues  of  character, 
independence,  age,
judgment, 
expertise,  diversity  of  experience,  length  of  service,  other
commitments and the like. While Coherent does not have a
formal policy with regard to the consideration of diversity in
identifying director nominees, as noted above, diversity of
experience  is  one  of  many  factors  that  the  committee
considers;

• the Governance and Nominating Committee evaluates such
factors, among others, and does not assign any particular

Majority Voting and Conditional
Resignations from the Board of
Directors

Since  2013,  we  have  had  a  majority  vote  standard  for  the
election  of  directors  in  elections  that  are  not  Contested
Elections (as defined below). This means that a nominee for
director in an uncontested election such as this one shall be
elected  to  the  Board  if  the  votes  cast  ‘‘for’’  such  nominee
exceed 
‘‘against’’  such  nominee  (with
abstentions and broker non-votes not counted as a vote cast
either ‘‘for’’ or ‘‘against’’ that director’s election). However, if
the number of nominees exceeds the number of directors to
be elected (a ‘‘Contested Election’’), our bylaws provide that
directors shall be elected by a plurality of the votes cast.

Stockholder Communication with the
Board of Directors

While  the  Board  believes  that  management  speaks  for
Coherent, the Board encourages direct communication from
stockholders. Accordingly, any stockholder may contact any
member of the Board individually or as a group by writing by
to  our  principal  executive  offices  (c/o  Corporate
mail 
Secretary) at 5100 Patrick Henry Dr., Santa Clara, CA 95054.

Any stockholder may report to us any complaints or comments
regarding accounting, internal accounting controls, or auditing
matters. Any stockholder who wishes to so contact us should
send such complaints or comments to the Audit Committee,
c/o  Corporate  Secretary,  at  our  principal  executive  offices.
Additionally,  as  noted  below,  our  Compensation  and  H.R.
Committee  encourages  stockholder  communication  on
matters related to executive compensation.

Proposal One Election of Directors

The  Board  has  also  adopted  a  policy  on  majority  voting  to
(i) establish procedures under which any incumbent director
who fails to receive a majority of the votes cast in an election
that  is  not  a  Contested  Election  shall  tender  his  or  her
resignation to the Governance and Nominating Committee for
consideration;  and  (ii)  provide  that  the  Governance  and
Nominating  Committee  will  make  recommendations  to  the
Board  regarding  the  actions  to  be  taken  with  respect  to  all
such offers to resign. The Board shall act on the resignation
within 90 days following certification of the election results. In
the  event  that  the  Board  does  not  accept  such  resignation,
then such director shall continue to serve until such time as his
or her successor is elected.

Any stockholder communications that the Board receives will
first  go  to  our  Corporate  Secretary,  who  will  log  the  date  of
receipt  of  the  communication  as  well  as  the  identity  and
contact  information  of  the  correspondent  in  our  stockholder
communications log.

Our  Corporate  Secretary  will  review,  summarize  and,  if
appropriate,  investigate  the  complaint  under  the  direction  of
the Board or appropriate committee of the Board in a timely
manner. In the case of accounting or auditing related matters,
a member of the Audit Committee, or the Audit Committee as
a whole, will then review the summary of the communication,
the results of the investigation, if any, and, if appropriate, the
draft response. The summary and response will be in the form
of  a  memo,  which  will  become  part  of  the  stockholder
communications  log  that  the  Corporate  Secretary  maintains
with respect to all stockholder communications.

Independent Chair and Board Leadership
The  Board’s  leadership  structure  consists  of  an  independent  Board  Chair,  who  is  elected  by  the  independent  directors,  and
independent  committee  chairs.  We  separate  the  positions  of  Chief  Executive  Officer  and  Board  Chair  in  recognition  of  the
differences between the two roles. The Board believes this structure provides independent Board leadership and engagement.

Given that our Chair is an independent director, the Board does not feel the need for a separate ‘‘lead independent director,’’ as
our independent Chair performs that function. The Board takes its independence seriously and reinforces this standard with,
following the Annual Meeting, seven of its eight members, or 88%, being independent.

The Role of the Board and Its
Committees in Risk Oversight

The  Board  oversees  Coherent’s 
risk  profile  and
management’s  processes  for  assessing  and  managing  risk,
both  as  a  Board  and  through  its  committees,  with  the
Governance  and  Nominating  Committee  delegated 
the
responsibility for assigning oversight responsibilities to each
committee  and  the  Board  as  a  whole.  Our  senior  executive
team  provides  regular  updates  to  the  Board  and  each
committee  regarding  our  strategies  and  objectives  and  the
risks inherent with them.

Each  regular  meeting  of  the  Board  includes  a  discussion  of
risks related to the Company’s financial results and operations
and  each  committee  schedules  risk-related  presentations
regularly throughout the year. In addition, our directors have
access to our management to discuss any matters of interest,
including 
risk.  Those  members  of
to 
management most knowledgeable of the issues attend Board
and committee meetings to provide additional insight on the
matters being discussed, including risk exposures. Our Chief
Financial Officer and General Counsel both report directly to
our Chief Executive Officer, providing him with further visibility
to our risk profile. A Vice President, Finance is the designated
officer  overseeing  our  enterprise  risk  management  program
and  works  closely  with  both  our  Chief  Financial  Officer  and
General Counsel on these matters.

These regular meetings also provide our Board members the
opportunity  to  discuss  issues  of  concern  directly  with

Additional Board Governance Matters

The Board (acting on the recommendation of the Governance
and  Nominating  Committee)  has  approved  the  Company’s
Corporate  Governance  Guidelines,  which  include,  among
other items (in addition to those items described elsewhere in
this proxy statement), the following provisions:

• At  each  regular  meeting  of  the  Board,  the  independent
directors  also  meet  in  executive  session  without  the
presence of management;

• To avoid ‘‘over-boarding’’ we maintain the following limits on

service on other boards:

• CEO—No  more  than  one  (1)  other  public  company
board  of  directors  in  addition  to  the  Company  (note,
however,  that  Mr.  Ambroseo  does  not  serve  on  any
public company boards other than ours);

management.  In  general  the  Board  and  its  committees
oversee the following risk categories:

• the  Board  generally  oversees  the  Company’s  overall
enterprise  risk  management  process  and  specifically  with
regard to the areas of strategy, mergers and acquisitions,
communications and operations;

• the  Audit  Committee  generally  oversees  risks  primarily
related  to  financial  controls,  IT,  accounting,  tax,  treasury,
capital, legal, regulatory and compliance;

• the Compensation and H.R. Committee generally oversees
our compensation programs so that they do not incentivize
excessive  risk  taking  as  well  as  overseeing  human
resources related risks; and

• the Governance and Nominating Committee oversees the
assignment of risk oversight categories by each particular
committee and/or the Board as a whole, as well as those
risks related to compensation of members of the Board and
succession planning for the Board and our Chief Executive
Officer.

Management  presents  an  annual  assessment  of  the  risks
associated  with  the  Company’s  compensation  plans.  The
Compensation  and  H.R.  Committee  agreed  with 
the
conclusion  from  the  first  quarter  of  fiscal  2019  presentation
that the risks were within our ability to effectively monitor and
manage and that these risks are not reasonably likely to have
a material adverse effect on the Company.

• Independent  Directors—No  more  than  four  (4)  other
public  company  boards  of  directors  in  addition  to  the
Company;

• Audit  Committee  members—No  more  than  three
(3) other public company audit committees in addition
to 
independent
directors consent;

the  Company,  unless 

the  other 

• Each  independent  member  of  the  Board  must,  within  five
years of initial appointment, acquire and thereafter maintain
a  minimum  value  of  Company  stock  equal  to  three  times
such director’s annual Board cash retainer (exclusive of any
cash retainer for service as chair or committee service);

• The  Board  is  responsible  for  reviewing  the  Company’s
succession planning and senior management development
on an annual basis; and

• The  Board  maintains  an  age-based  term  limit  of  72
(provided, that the Governance and Nominating Committee

Proposal One Election of Directors

maintains the flexibility to not apply such limit on a facts and
circumstances basis).

Fiscal 2018 Director Compensation
During fiscal 2018, we paid our non-employee directors an annual retainer (depending upon position) and for service on the Board
as follows:

Position

Board Member
Board Chair
Audit Committee Chair
Compensation and H.R. Committee Chair
Governance and Nominating Committee Chair
Audit Committee member (non-Chair)

$ 12,500
$ 10,000
6,500
$

(1) On December 6, 2018, after reviewing materials provided by its compensation consultant, the Governance and Nominating
Committee approved an increase to the annual retainer of the Board Chair from $50,000 to $60,000 effective as of the
beginning of the second quarter of fiscal 2019.

The  Governance  and  Nominating  Committee  annually
reviews  Board  and  committee  compensation  with 
the
assistance of an independent compensation consultant, which
for  fiscal  2018  was  Compensia.  Compensia  is  separately
compensated  for  this  work  from  the  work  it  does  as  the
Compensation and H.R. Committee’s independent consultant
for  executive  compensation.  The  annual  review  includes  a
comparison to peer companies (which are the same as used
for executive compensation as noted on page 36) and market

pay practices for service on boards of directors. Compensia
advised the committee that the design and pay levels of the
director compensation program were aligned with peer market
practices, with the annual retainer for the Board Chair below.
As  noted,  the  Board  is  compensated  with  a  combination  of
cash  retainers  and  a  fixed  value  of  time-based  RSUs.  As
noted elsewhere in this proxy statement, Compensia has not
provided  any  other  service  for  the  Company  other  than  as
directed by a committee of the Board.

* Mr. McMullen joined the Board effective September 28, 2018, the day prior to the last day of our 2018 fiscal year. Therefore,
Mr. McMullen did not receive any cash retainer for his Board service during fiscal 2018. However, Mr. McMullen did receive
an award of RSUs under the 2011 Plan at the time of his initial appointment to the Board in accordance with the Company’s
standard practice, as described below.

* Mr. McMullen joined the Board effective September 28, 2018, the day prior to the last day of our 2018 fiscal year.

Therefore, Mr. McMullen did not receive any cash retainer for his Board service during fiscal 2018.

(2) These amounts do not reflect compensation actually received. Rather, these amounts represent the aggregate grant date
fair value computed in accordance with ASC 718, for restricted stock units (‘‘RSUs’’) which were granted in fiscal 2018. The
assumptions used to calculate the value of these RSUs are set forth in Note 12 ‘‘Employee Stock Award and Benefit Plans’’
of  the  Notes  to  the  Consolidated  Financial  Statements  in  our  annual  report  on  Form  10-K  for  fiscal  2018.  Note  that
Mr. McMullen’s stock awards are at a different value due to the difference in stock price on the date of his grant date as
compared to the other directors, who received their grants on a different date.

(3) The aggregate number of shares underlying unvested RSUs held by each of our non-employee directors as of the end of

fiscal 2018 and reflecting the grants made to our non-employee directors during fiscal 2018 was as follows:

(d) 50% of the shares are scheduled to vest on each of September 28, 2019 and September 28, 2020.

(4) No stock options were granted to our non-employee directors during fiscal 2018. As of the end of fiscal 2018, Mr. Flatley
held outstanding stock options with respect to 24,000 shares and none of the other non-employee directors held any stock
options.

Our  stockholders  approved  the  adoption  of  our  2011  Equity
Incentive Plan (the ‘‘2011 Plan’’) at our annual meeting held in
March  2011  and  re-approved  the  2011  Plan  at  our  annual
meeting held in March 2017.

Following  the  recommendation  of  the  Governance  and
Nominating Committee (based upon review by Compensia) in
February 2017, the Board adopted resolutions automatically
granting  each  year  without  any  discretion 
to  each
non-employee director an award of RSUs under the 2011 Plan
(rounded  down  to  the  nearest  whole  share)  valued  at
$225,000 (based on the trailing thirty day closing price of the
Company’s  common  stock  on  the  Nasdaq  Stock  Market
measured from the last trading day prior to the date of grant)

upon  the  director’s  election  to  the  Board  at  the  Company’s
annual meeting. In addition, the Board determined that upon
the  initial  appointment  of  a  non-employee  director,  such
director will receive an award of RSUs under the 2011 Plan
valued  at  $225,000  (based  on  the  trailing  thirty  day  closing
price of the Company’s common stock on the Nasdaq Stock
Market measured from the last trading day prior to the date of
grant), which RSUs shall vest over two years (fifty percent on
each anniversary of the date of grant). This was a change from
the  historical  practice  of  granting  a  fixed  number  of  3,500
RSUs per year. The Board determined to migrate to a value-
based annual grant rather than fixed shares.

Vote Required

The affirmative vote of a majority of the votes cast is required
for the election of directors. You may vote ‘‘FOR,’’ ‘‘AGAINST’’
or ‘‘ABSTAIN’’ with respect to each of the director nominees
named  in  this  proxy  statement.  Pursuant  to  our  bylaws,
abstentions  and  broker  non-votes  are  not  considered  to  be
votes cast and, therefore, will not have an effect in determining
the outcome of the election of directors, and votes withheld will
count as a vote against a nominee’s election. If a quorum is
present,  each  of  the  eight  (8)  nominees  who  receives  more
‘‘FOR’’ votes than ‘‘AGAINST’’ votes will be elected.

Every  stockholder  voting  for  the  election  of  directors  may
cumulate such stockholder’s votes and give one candidate a
number of votes equal to the number of directors to be elected
multiplied by the number of votes to which the stockholder’s
shares are entitled. Alternatively, a stockholder may distribute
his  or  her  votes  on  the  same  principle  among  as  many
candidates  as  the  stockholder  thinks  fit,  provided  that  votes

cannot be cast for more than eight (8) candidates. However,
no  stockholder  will  be  entitled  to  cumulate  votes  for  a
candidate unless (i) such candidate’s name has been properly
placed in nomination for election at the Annual Meeting prior to
the voting and (ii) the stockholder, or any other stockholder,
has  given  notice  at  the  meeting  prior  to  the  voting  of  the
intention  to  cumulate  the  stockholder’s  votes.  If  cumulative
voting occurs at the meeting and you do not specify how to
distribute  your  votes,  your  proxy  holders  (the  individuals
named  on  your  proxy  card)  will  cumulate  votes  in  such  a
manner as will ensure the election of as many of the nominees
listed  above  as  possible,  and  the  specific  nominees  to  be
voted for will be determined by the proxy holders.

Recommendation
The  Board  recommends  that  stockholders  vote  ‘‘FOR’’
each of the eight nominees presented herein.

PROPOSAL TWO
RATIFICATION OF THE APPOINTMENT OF
DELOITTE & TOUCHE LLP AS INDEPENDENT
REGISTERED PUBLIC ACCOUNTING FIRM

The  Audit  Committee  of  the  Board  has  selected  Deloitte  &
Touche  LLP,  an  independent  registered  public  accounting
firm, to audit our financial statements for the fiscal year ending
September 28, 2019, and recommends that stockholders vote
for  ratification  of  such  appointment.  Deloitte  &  Touche  LLP
has  audited  our  financial  statements  since  the  fiscal  year
ended  September  25,  1976.  Although 
ratification  by
stockholders is not required by law, the Audit Committee has
determined  that  it  is  desirable  to  request  ratification  of  this
selection by the stockholders as a matter of good corporate
practice. Notwithstanding its selection, the Audit Committee,
in  its  discretion,  may  appoint  a  new  independent  registered
public accounting firm at any time during the year if the Audit

Committee believes that such a change would be in the best
interest of Coherent and its stockholders. If stockholders do
not ratify the appointment of Deloitte & Touche LLP, the Audit
Committee may reconsider its selection. The Audit Committee
selected  Deloitte  &  Touche  LLP  to  audit  our  financial
statements  for  the  fiscal  year  ended  September  29,  2018,
which was ratified by our stockholders.

Representatives of Deloitte & Touche LLP are expected to be
present at the meeting and will be afforded the opportunity to
make a statement if they desire to do so. The representatives
of Deloitte & Touche LLP are also expected to be available to
respond to appropriate questions.

Principal Accounting Fees and Services
The  following  table  sets  forth  fees  for  services  provided  by  Deloitte  &  Touche  LLP,  the  member  firms  of  Deloitte  Touche

PROPOSAL THREE
APPROVAL ON A NON-BINDING, ADVISORY BASIS,
OF OUR NAMED EXECUTIVE OFFICER
COMPENSATION

At  our  annual  meeting  in  March  2017,  our  stockholders
indicated they would like to have an annual advisory vote on
executive  compensation.  Accordingly,  the  Board  proposes
that stockholders provide advisory (non-binding) approval of
the  compensation  of  our  named  executive  officers,  as
disclosed pursuant to the compensation disclosure rules of the
SEC,  including  the  Compensation  Discussion  and  Analysis,
the  Fiscal  2018  Summary  Compensation  Table  and  related
tables and disclosure.

As described in our Compensation Discussion and Analysis,
we  have  adopted  an  executive  compensation  philosophy
designed  to  provide  alignment  between  executive  pay  and
performance and to focus executives on making decisions that
enhance our stockholder value in both the short and long term.
Executives  are  compensated  in  a  manner  consistent  with
Coherent’s  strategy,  competitive  practices,  stockholder
interest  alignment,  and  evolving  compensation  governance
standards.

Recommendation
The  Board  recommends  that  stockholders  vote  ‘‘FOR’’
the  approval,  on  a  non-binding,  advisory  basis  of  our
named executive officer compensation disclosed in this
proxy statement.

Vote Required
The affirmative vote of a majority of votes present in person or
represented  by  proxy  and  entitled  to  vote  at  the  Annual
Meeting  is  required  to  approve  the  compensation  of  our
named  executive  officers  disclosed  in  this  proxy  statement.
The vote is an advisory vote and, therefore, not binding. The
Board  values  the  opinions  of  our  stockholders  and  to  the
extent  there  is  any  significant  vote  against  our  named
executive  officer  compensation  as  disclosed  in  this  proxy
statement, the Board will consider our stockholders’ concerns
and  the  Compensation  and  H.R.  Committee  will  evaluate
whether  any  actions  are  necessary  to  address  those
concerns.

Section 16(a) Beneficial
Ownership Reporting
Compliance

Section 16(a) of the Exchange Act requires our officers and
directors, and persons who own more than ten percent of a
registered  class  of  our  equity  securities  to  file  reports  of
ownership  and  changes  in  ownership  with  the  SEC.  Such
officers,  directors  and  ten-percent  stockholders  are  also
required by SEC rules to furnish us with copies of all forms that
they file pursuant to Section 16(a). Based solely on our review

of  the  copies  of  such  forms  received  by  us,  and  on  written
representations from certain reporting persons that no other
reports  were  required  for  such  persons,  we  believe  that,

COMPENSATION DISCUSSION AND ANALYSIS

Introduction
In this section, we describe the material components of our executive compensation program for our ‘‘Named Executive Officers’’
or  ‘‘NEOs’’:  Messrs.  Ambroseo,  Palatnik,  Sobey,  Sechrist  and  DiMarco.  We  also  provide  an  overview  of  our  executive
compensation philosophy, principal compensation policies and practices by which the Compensation and H.R. Committee, or the
committee, arrives at its decisions regarding NEO compensation. While this section is focused on compensation for our 2018
fiscal year, we also discuss in this section the design changes made by the committee for executive compensation beginning in
our 2019 fiscal year.

NEO Compensation Overview
The following chart sets forth our compensation philosophy and design principles:

Compensation Philosophy

Compensation Design Principles

Retain and hire talented
executives

Pay for performance, with both
short and long-term
measurements

Our executives should have market competitive compensation and the committee
orients our target total compensation generally near the 50th percentile of the
committee’s selected peer group, with actual compensation falling above or below
depending upon our financial performance and the performance of our stock price
against an index over a three-year vesting period. Compensation components
may be above or below such percentile target and varies by individual executive.
A significant portion of the annual compensation of our executives is designed to
vary with annual business performance and a significant portion of long-term
equity compensation is based on the long-term relative performance of our stock
price in comparison to the Russell Index (by way of a single three year vesting
period).

Align compensation with
stockholder interests

Tie compensation to performance Our fiscal 2018 annual cash incentive plan was dependent upon corporate
achievement of two performance targets based on: revenue and Adjusted
of the core business
EBITDA dollars. The committee determined that these were the most effective
metrics for tying management’s compensation directly to our core operating
results for fiscal 2018.
Our stockholders benefit from continued strong operating performance by the
Company, and we believe that having a significant portion of compensation tied to
equity with both time and performance-based vesting requirements directly aligns
management to stockholder returns. Performance-based RSUs make up the
largest potential portion of the equity grants for our CEO, and make up a
significant potential portion of the equity grants of our other NEOs. Grants of
performance-based RSUs in fiscal 2018 have the same measurement period
consistent with historical practice: a single vesting date three years from grant
solely dependent upon the performance of our common stock price measured
against the Russell Index, with target at meeting the index’s performance. Prior to
fiscal 2018 we used the Russell 2000 Index to compare our stock price
performance, but due to the recent increase in our market cap, we have been
moved to the Russell 1000 Index and, accordingly, for grants made in the first
quarter of fiscal 2018 and fiscal 2019 the committee compares our stock price
performance against the performance of the Russell 1000 Index. We refer to the
applicable Russell Index as the ‘‘Russell Index.’’

Stockholder Feedback
The  committee  considers  feedback  from  our  stockholders
regarding our executive compensation program, including as
expressed  by  the  results  of  our  annual  advisory  vote  on
executive  compensation,  which  our  stockholders  have
historically strongly supported. Although we had strong pay for
performance  alignment  and  the  say  on  pay  for  fiscal  2017
compensation  was  approved  by  an  overwhelming  majority,
the say on pay vote approval was lower than in prior years. We
attributed such lower level of support to comments from one of
the  principal  proxy  advisory  firms.  Members  of  our  senior
management team met with the advisory firm and discussed
our approach to compensation. Following our annual meeting
in  March,  2018,  we  received  correspondence  from  one
stockholder with whom we were able to exchange views on
compensation  design  directly. 
to  such
discussions  and  taking  into  account  the  ‘‘say  on  pay’’  vote
results  in  March,  2018,  we  modified  the  design  of  our
performance-based RSU grants. Such grants made in the first
quarter  of  fiscal  2019  now  require  performance  above  the
Russell Index in order to obtain a target award.

We encourage our stockholders to directly express their views

the  heading  ‘‘Stockholder  Communication  with  the  Board  of
Directors.’’  The  committee  welcomes  direct  stockholder
feedback  and  considers  such  feedback  as  well  as  our
historical ‘‘say on pay’’ results in its deliberations on executive
compensation.  From  a  timing  perspective,  however,  the
committee generally meets in our first fiscal quarter (which are
the  last  months  of  the  calendar  year)  to  make  decisions  on
executive  compensation  for  the  then  current  fiscal  year.  In
contrast,  our  annual  meeting  is  held  in  the  spring  and
stockholders are asked to vote on compensation for a fiscal
year  which  was  already  completed.  Accordingly, 
the

as  noted  above,  in  the  first  fiscal  quarter  of  2019,  the
committee  made  changes  to  our  fiscal  2019  compensation
design in response to such feedback and review as described
below.

We strongly urge our stockholders to read this Compensation
Discussion and Analysis in conjunction with Proposal Three.

Our Chief Executive Officer and Chief Financial Officer regularly meet with our stockholders throughout the year, primarily to
discuss financial and business matters related to the Company. The feedback from those meetings are considered by the Board
and the committee in deliberations on such topics throughout the year.

Compensation Discussion and Analysis

Design Changes to Executive
Compensation in Fiscal 2019

In fiscal 2019, the committee made the following changes to
the design of executive compensation:

• Considered internal pay equity between the CEO and other

NEOs as a factor in determining compensation.

• Redesigned 

the  measurement  of 

the  Company’s
performance-based  RSUs  to  require  performance  above
the Russell Index in order to achieve target grant levels;

• Moved the annual cash Variable Compensation Plan to a

single one year measurement period; and

Selected Business Highlights
We  experienced  10%  growth  in  year-over-year  revenue  in
fiscal 2018, which met our internal growth targets. In addition,
we  experienced  growth 
in  our  Adjusted  EBITDA  and
non-GAAP earnings per share. While the Company exceeded
the 
executive
compensation  programs  in  the  first  half  of  the  year  for  our
annual  cash  program,  the  Company  underperformed  as
compared to target metrics in the second half of fiscal 2018.
As a result, you will see in the coming pages that in fiscal 2018

Compensation Overview
Compensation  Philosophy. We 
total
compensation  to  stockholder  value  with  two  measures:  our
operational  results  and  the  comparative  performance  of  our
stock price. This approach provides strong alignment between
executive  pay  and  performance,  and  focuses  executives  on

executive 

tie 

making decisions that enhance our stockholder value in both
the  short  and 
long-term.  We  design  our  executive
compensation program to achieve the following goals:

• Pay  for  performance,  with  both  short  and  long-term
the  annual
measurements—A  significant  portion  of 
compensation  of  our  executives  is  designed  to  vary  with
annual  business  performance  and  the  long-term  relative
performance of Coherent’s stock price in comparison to the
Russell Index (by way of a single three year vesting period).
The  committee  and  management  set  demanding
performance targets. For example, there was a de minimus
bonus  paid  out  for  the  second  half  of  fiscal  2018  as
explained below. For the first half of fiscal 2018, the bonus
payout was 184.05% of target for a combined bonus payout
for fiscal 2018 of 92.81% of target. The performance of the
Company’s  stock  as  measured  against  the  Russell  Index
resulted in maximum shares issued under the performance-
based  RSUs,  which  vested  in  November,  2018  at  the
maximum 200% payout.

The  following  chart  shows  the  payout  percentages  as
compared to the committee’s selected target for each of the
last three fiscal years under our annual cash bonus plan:

• Tie  compensation 

to  performance  of 

the  core
business—Our fiscal 2018 annual cash incentive plan was
dependent  upon  Coherent’s  achievement  against  two
criteria:  Adjusted  EBITDA  dollars  and  revenue.  The
committee  determined  that  these  were  the  most  effective
metrics  for  tying  management’s  compensation  directly  to
Coherent’s core operating results for fiscal 2018.

• Retain  and  hire  talented  executives—Our  executives
should  have  market  competitive  compensation,  and  the
committee orients our target total compensation generally
near  the  50th  percentile  of  the  committee’s  selected  peer
group  (as  noted  below),  with  actual  compensation  falling
above  or  below  depending  upon  Coherent’s  financial
performance. 
compensation
components may be above or below such percentile target
and varies by individual executive.

Additionally,

• Align  compensation  with  stockholder  interests—Our
stockholders  benefit  from  continued  strong  operating
performance by the Company and we believe that having a
significant portion of compensation tied to equity, with both
time and performance-based vesting requirements, directly
aligns  management 
returns.  The
performance-based  RSUs  make  up  the  largest  potential
portion  of  the  equity  grants  for  our  CEO.  Grants  of
performance-based  RSUs  historically  have  the  same
measurement period: a single vesting date three years from
grant solely dependent upon the performance of Coherent’s
common stock price measured against the Russell Index,
with target equal to meeting the index’s performance. For
each  1%  that  Coherent’s  common  stock  exceeds  the
performance of the Russell Index for the trailing 90 trading
days  from  the  vesting  measurement  date  against  the
comparable period from the date of grant, the grant recipient
will get a 2% increase in the number of shares above target
(up to a maximum cap of 200% of target), and for each 1%
below the Russell Index’s performance, a 4% decrease in
the  number  of  shares  below  target  (down  to  zero).  As  a
result, compensation decreases faster for failing to achieve
the  target  than  it  increases  for  exceeding  it.  If  Coherent’s
stock  underperforms  the  Russell  Index  performance  by
more than 25%, then there is no payout, but in order to hit

Performance (Percentage Points vs. Index)

As mentioned above, the committee has modified the design
of the performance-based RSUs made in the first quarter of
fiscal 2019 to require performance above the Russell Index to
achieve the targeted payout.

Elements  of  Executive  Compensation. During  fiscal  2018,
the compensation of our NEOs primarily consisted of (A) base
salary, (B) participation in our annual variable compensation
plan (referred to herein as our ‘‘annual cash incentive plan’’ or
‘‘VCP’’),  and  (C)  long-term  equity  incentive  awards  divided
between  time-based  RSUs  and  performance-based  RSUs.
For fiscal 2018, on average, approximately 80% of our NEO’s
target  compensation  and  approximately  92%  of  our  CEO’s
target compensation was delivered through our cash incentive

been  and  remains  at  the  core  of  Coherent’s  executive
compensation coupled with appropriately managing risk and
aligning  our  compensation  programs  with 
long-term
stockholder interests. We accomplish this primarily by having
a majority of our NEOs’ potential compensation being ‘‘at risk’’
through  a  combination  of  (i)  a  fiscal  year  variable  cash
incentive program tied to achievement of financial metrics and
(ii) equity grant vesting tied to achievement of a performance
metric.  The  committee  monitors  and  considers  evolving
governance  approaches  and  standards 
in  executive
compensation, as well as communications it receives directly
from stockholders.

As more fully discussed below, recent examples of how this
philosophy  is  applied  and  changes  made  pursuant  to
compensation  practices  as  well  as  governance  practices  in
effect during fiscal 2018, include:

• We  have  minimum  share  ownership  requirements  for  our
Chief Executive Officer and members of the Board as well

consultant;

• We  have  eliminated  material  historical  perquisites  as  an

element of compensation for our NEOs;

• We have a recoupment or ‘‘claw-back’’ policy for our Chief
Executive Officer and Chief Financial Officer, as described
below;

• We  prohibit  employees  and  directors  from  hedging  or

pledging Company stock;

• Our change-of-control plan provides for payment solely in
‘‘double-trigger’’ circumstances, that is a change of control
coupled with a termination of employment within a defined
time period;

• None of our NEOs are entitled to any ‘‘gross-up’’ to offset
the  impact  of  IRS  Code  Sections  280G  or  4999  in
connection with a change of control; and

• None of our NEOs have employment agreements.

Our  stockholders  have  historically  strongly  supported  our
executive compensation philosophy and design as seen in the
significant  majorities  approving  our  ‘‘say  on  pay’’  proposal
(does not include broker non-votes; rounded). We saw some
drop in support for the ‘‘say on pay’’ proposal at the fiscal 2018
meeting which we attributed to the impact of comments made
by one of the principal proxy advisory firms. As indicated above,
we  met  with  the  advisory  firm  and  have  implemented  certain
changes  to  our  compensation  program  in  response  to  their
comments and the feedback we received from a stockholder.

Role of the Committee’s Compensation Consultant
The  committee  utilizes  the  services  of  an  independent
compensation  consultant  and 
fiscal  2018,  engaged
Compensia  as  its  independent  compensation  consultant.
Compensia assisted the committee by:

in 

• Reviewing  and  analyzing  our  executive  compensation
program,  including  providing  NEO  tally  sheets  to  the
committee;

• Providing  market  data  and  ranges 

for

compensation; and

• Providing  further  insight  on  compensation  governance

trends.

Additionally,  in  fiscal  2018,  Compensia  was  retained  by  the
Governance  and  Nominating  Committee  to  review,  analyze
and  make  recommendations  regarding  compensation  for
service on the Board and its committees.

The  independent  compensation  consultant  serves  at  the
discretion of the committee and is not permitted to do other work
for  Coherent  unless  expressly  authorized  by  the  committee.
Since  retention,  Compensia  has  not  performed  any  work  for
Coherent other than its work with the committee, the Board or
other  committees  of  the  Board.  The  committee  is  focused  on
maintaining  the  independence  of  its  compensation  consultant
and,  accordingly,  does  not  anticipate  having  its  consultant
perform any other work for the Company in addition to its direct
work for the committee, the Board, or another committee of the
Board.  The  committee  has  assessed  the  independence  of
Compensia and concluded that no conflict of interest exists.

The  Company  also  participates 
in  and  maintains  a
subscription to the Radford Global Technology Survey. This
survey provides benchmark data and compensation practices
reports  of  a  broad  cross-section  of  technology  companies
similar  in  size  to  Coherent  to  assist  us  with  employee
compensation generally.

Role of Management
The committee regularly meets with Mr. Ambroseo, our Chief
Executive Officer, to obtain recommendations with respect to
the compensation programs, practices and packages for our
NEOs other than Mr. Ambroseo. Additionally, Mr. Palatnik, our
Executive  Vice  President  and  Chief  Financial  Officer,
Mr. DiMarco, our Executive Vice President, General Counsel
and  Corporate  Secretary,  and  members  of  our  human
resources department are regularly invited to meetings of the
committee or otherwise asked to assist the committee.

The assistance of these individuals includes providing financial
information and analysis for the committee and its compensation
consultant,  taking  minutes  of  the  meeting  or  providing  legal
advice,  developing  compensation  proposals  for  consideration,

consultant and, when applicable, including, for example, when
there are few comparable positions reported in the proxy data
of our peer group companies, data from the Radford Global
Technology Survey), resulting in targeted total compensation
that is competitive for performance that meets the objectives
established by the committee. An NEO’s actual salary, cash
incentive compensation opportunity and equity compensation
grant value may fall below or above the target position based
on the individual’s performance, contributions, scope of role,
experience, skills and knowledge, as well as the historical pay
structure for each executive, Company performance and the
proportion of compensation at risk. These factors are weighed
by the committee in its judgment, and no single factor takes
precedence  over  others  nor  is  any  formula  used  in  making
these  decisions  nor  was  the  impact  of  any  factor  on  the
determination  of  compensation  quantifiable.  In  general  the
committee  will  balance  between  cash  and  equity
compensation elements to have more compensation in equity
for  each  NEO 
to  more  closely  align  NEO
compensation  directly  with  that  of  the  performance  of  the
Company and with stockholders. In fiscal 2019, the committee
also asked its independent compensation consultant to review
and report on internal pay equity between the CEO and the
other NEOs as a factor when approving compensation.

considered 

In analyzing our executive compensation program relative to
target market positioning, the committee reviews information
provided by its independent compensation consultant, which
includes  an  analysis  of  data  from  peer  companies’  proxy
filings with respect to similarly situated individuals at the peer
the  Radford  Global
companies  (when  available)  and 
Technology  Survey  (as  a  supplement  when  peer  group
company data is unavailable). It is important to note that these
are the peers selected by the committee. The committee uses
criteria  as  described  below  in  determining  the  appropriate
peer group. There are proxy advisory services that use their
own criteria to select peers for the Company and, accordingly,
stockholders should be aware that these advisory services do
not, in fact, follow the same methodology of the committee and
there  may  be  wide  variances  between  the  different  peer
groups used by these services. Any comparison of company

performance or market data for executive compensation using
a  completely  different  peer  group  will,  therefore,  naturally
result in a different analysis. We encourage our stockholders
to consider the peer group used in any comparisons and direct
any questions to the committee regarding such comparisons
or  any  other  matters  when  considering  how  to  vote  on
Proposal Three.

For pay decisions made for fiscal 2018, after consulting with
our  independent  compensation  consultant,  the  committee
determined  that  the  following  companies  comprise  the  peer
group for fiscal 2018:

Dolby Laboratories (DLB)

Entegris (ENTG)
F5 Networks (FFIV)

Finisar (FNSR)

FLIR Systems (FLIR)
Infinera (INFN)
Keysight Technologies
(KEYS)
Lumentum Holdings, Inc.

National Instruments
(NATI)
Nuance Communications
(NUAN)
OSI Systems (OSIS)
Plantronics (PLT)
Synaptics (SNYA)

Teradyne (TER)

ViaSat (VSAT)

Several factors are considered in selecting the peer group, the
most important of which are:

Primary Criteria
• Industry (primarily companies in the Electronic Equipment
and Semiconductor sub-industry classifications defined by
the Global Industry Classification Standard (GICS) system);
and

• Revenue level (primarily companies with annual revenues

between 0.5x-2.0x that of Coherent).

Secondary Criteria
• Market capitalization between 0.25x and 3.0x of Coherent;

• Market  capitalization  as  a  multiple  of  revenues  of  greater

than 1.5x; and

• A disclosed peer of a peer company.

The  committee  reviews  the  composition  of  the  peer  group
annually to ensure it is the most relevant set of companies to
use 
for  comparison  purposes.  Dolby  Laboratories,  F5
Networks and Maxim Integrated Products were added to the

companies  comprising  the  Company’s  peer  group  for  fiscal
2018  replacing  four  companies  from  the  fiscal  2017  peer
group which were acquired.

Components of Our Executive
Compensation Program
The  principal  components  of  our  executive  officer
compensation  and  employment  arrangements  during  fiscal
2018 included:

• Base salary;

• Annual cash incentive plan;

• Equity awards; and

• Other benefits.

These  components  were  selected  because  the  committee

and competitively compensate our executives for the jobs we
ask them to perform. This is the most stable component of our
executive compensation program, as this amount is not at risk.
The committee reviewed market data information provided by
Compensia  with  respect  to  similarly  situated  individuals  to
assist  it  in  determining  the  base  salary  for  each  NEO,
depending upon the particular executive’s experience, skills,
knowledge,  performance  and  contribution.  The  committee
increased the base salaries of our NEOs other than the CEO
in  fiscal  2018,  as  supported  by  compensation  analysis
provided by Compensia, from 2% to 8% to more closely align
their base salary with the base salary of peers. According to
information provided by our compensation consultant, none of
the increases brought base salary above the 50th percentile of
our  peer  group  companies.  For  several  of  our  NEOs,  base
salary remained below the 50th percentile of our peer group.
Our CEO did not receive a base salary increase in fiscal 2018
and has not received a base salary increase in eight of the last
ten years.

Variable Cash Incentive Compensation
A substantial portion of each individual’s potential short-term
compensation  is  in  the  form  of  variable  incentive  cash
compensation  tied  to  committee-established  goals.  In  fiscal
2018, Coherent maintained one incentive cash program under
which executive officers were eligible to receive annual cash
incentives,  the  2018  Variable  Compensation  Plan  (‘‘2018
VCP’’).

2018 VCP
The  2018  VCP  was  designed  as  an  ‘‘at  risk’’  bonus
compensation  program  to  promote  a  focus  on  Coherent’s
growth and profitability. It provided an incentive compensation
opportunity  in  line  with  targeted  market  rates  to  our  NEOs.
Under  the  2018  VCP,  participants  were  eligible  to  receive
bi-annual bonuses (with measurement periods for the first half
and  the  second  half  of  the  2018  fiscal  year).  In  setting  the
performance  goals  at  the  beginning  of  the  fiscal  year,  the
committee assessed the anticipated difficulty and importance
to  the  success  of  Coherent  of  achieving  the  performance
goals.

The  actual  awards  (if  any)  payable  for  each  semi-annual
period depend on the extent to which actual performance met,
exceeded or fell short of the goals approved by the committee.
The 2018 VCP goals were tied to Coherent achieving varying
levels  of  revenue  and  Adjusted  EBITDA  dollars  (‘‘Adjusted
EBITDA’’),  with  revenue  weighted  at  25%  and  Adjusted
EBITDA  weighted  at  75%.  Each  performance  metric  is
measured and paid out independently, but the revenue payout
is  capped  at  100%  achievement  until  Adjusted  EBITDA

reaches a minimum dollar target. Adjusted EBITDA is defined
as operating income adjusted for VCP payouts, depreciation,
amortization, 
expenses,  major
restructuring  charges  and  certain  non-operating  income  or
expense  items,  such  as  costs  related  to  our  acquisition  of
Rofin.  The  committee  also  reviews  the  financial  impact  of
mergers and acquisitions to determine if any adjustments in
VCP are required.

Each  measurement  period  had  the  same  range  of  between
zero  and  200%,  with  target  at  100%  of  the  executive’s
participation rate.

Equity Awards
We  believe  that  equity  awards  provide  a  strong  alignment
between the interests of our executives and our stockholders.
We  seek  to  provide  equity  award  opportunities  that  are
consistent  with  our  compensation  philosophy,  with  the
potential  for  increase  for  exceptional  financial  performance,
consistent with the reasonable management of overall equity
compensation  expense  and  stockholder  dilution.  Finally,  we
believe that long-term equity awards are an essential tool in
promoting executive retention. For fiscal 2018, our long-term
incentive program included the grant of time-based RSUs and
performance-based  RSUs.  These  components  provide  a
reward for past corporate and individual performance and an
incentive for future performance.

Compensation Discussion and Analysis

Fiscal 2018 Equity Grants
For fiscal 2018, the committee based the equity program on a
combination  of  time-based  and  performance-based  RSUs
over  a  three-year  period.  In  particular,  the  committee
determined  to  measure  achievement  for  the  performance
grants by the relative performance of Coherent’s stock price in
comparison to the Russell Index. The committee believed that
using the Russell Index (in which Coherent was a member at
the time of grant) as a proxy of total stockholder return directly
aligns executive compensation with stockholder interest. The
committee determined that both the performance-based and
time-based RSU grants provide a further retention tool in that
the  time-based  grants  vest  over  three  years  with  pro  rata
annual  vesting  and,  for  the  performance-based  grants,  a
single measurement period three years from the date of grant
with three-year cliff vesting thereafter if such grants vest at all
because such grants vest purely based on performance.

Performance-based  RSU  grants  in  fiscal  2018  vest  solely
dependent  upon  the  performance  of  Coherent’s  common
stock price measured against the Russell Index. For each 1%
that  Coherent’s  common  stock  exceeds  the  performance  of
the  Russell  Index  for  the  trailing  90  trading  days  from  the
vesting  measurement  date  against  the  comparable  period
from  the  date  of  grant,  the  grant  recipient  will  get  a  2%
increase  in  the  number  of  shares  above  target  (up  to  a
maximum cap of 200% of target), and for each 1% below the
Russell Index’s performance, a 4% decrease in the number of
shares (down to zero). As a result, compensation decreases
faster  for  failing  to  achieve  the  target  than  it  increases  for
exceeding  it.  The  performance-based  RSUs  make  up  the
largest  potential  portion  of  the  equity  grants  for  our  Chief
Executive Officer.

The following table summarizes some of the key features of our general fiscal 2018 equity grants:

For our Chief Executive Officer, greater than half of his total
equity awards are performance-based. Approximately 71%
of his equity awards are performance-based and at maximum
achievement  that  percentage  increases  to  approximately
83%.

As an example, our performance-based design was seen in
the  vesting  of  the  PRSU  grants  made  in  November  2014,
which vested in the first quarter of fiscal 2018. Our common
stock  at  the  time  of  grant  was  $64.84  and  gained  393%  as
compared to the Russell Index, which gained 126% over the

same three-year measurement period. This out-performance
resulted in 200% PRSU vesting.

The following tables reflect the number of shares subject to
equity grants made to the NEOs during fiscal 2018:

In  the  event  of  a  change  of  control  of  the  Company,  the
performance-based grants will be measured, with respect to
performance periods not yet completed, by the relative stock
performance of Coherent in comparison to the Russell Index
through  the  date  of  the  change  of  control  and  such

Equity Award Practices
Equity  grants  to  our  employees  are  driven  by  our  annual
review  process.  Grant  guidelines  are  based  on  competitive
market  practices.  Typically,  an  eligible  employee  is  granted
first  committee  meeting  after  beginning
equity  at 
employment and may be eligible for periodic grants thereafter.
Eligibility  for  and  the  size  of  grants  are  influenced  by  the
then-current  guidelines  for  non-executive  officer  grants  and
the individual’s performance or particular requirements at the
time of hire. No option grants have been made to an employee
since 2010.

(at  maximum),

stock  units 

In fiscal 2018 the committee granted an aggregate of 152,776
time-based  and  performance-based
shares  subject 
restricted 
representing
approximately  0.63%  of  Coherent’s  outstanding  common
stock  as  of  September  29,  2018  (excluding  automatic  and
initial grants to directors). With the assistance of Compensia,
the  committee  has  reviewed  this  burn  rate  relative  to  peer
practices and proxy advisory firm guidance and found that the
total dilution was consistent with the median of peer practices
and such guidance.

During fiscal 2018 all equity grants were made at meetings of
the committee.

Chief Executive Officer and Executive Minimum Stock
Ownership Guidelines
The  committee  adopted  mandatory  stock  ownership
guidelines for our Chief Executive Officer during fiscal 2012.
During the first quarter of fiscal 2018, the committee adopted
enhanced stock ownership guidelines increasing the value of
shares our Chief Executive Officer must hold to at least five
times base salary and making our Executive Vice Presidents
and Senior Vice Presidents reporting to the Chief Executive
Officers  subject  to  stock  ownership  guidelines  of  one  times
such  individual’s  base  salary.  In  the  event  that  our  Chief
Executive Officer or other officer does not satisfy the minimum
requirements, 
the  net  after-tax  shares
(e.g.  exercised  options/shares  received  on  the  vesting  of

then  50%  of 

RSUs) are required to be held until the guidelines are met. As
of December 31, 2018, Mr. Ambroseo held outstanding stock
worth  more  than  20 times  his  base  salary  and,  accordingly,
significantly  exceeded 
the  minimum  stock  ownership
guidelines. Our other NEOs also exceeded the minimum stock
ownership guidelines.

Other Benefits
Retirement Plans
U.S. based executive officers are eligible to participate in our
401(k) Retirement Plan on the same terms as all other U.S.
employees, including a 4% Company matching contribution.
Our 401(k) Retirement Plan is intended to be a tax-qualified
plan and therefore is subject to certain Internal Revenue Code
limitations  on  the  dollar  amounts  of  deferrals  and  Company
contributions  that  can  be  made  to  plan  accounts.  These
limitations apply to our more highly-compensated employees
(including the NEOs).

We  maintain  a  Deferred  Compensation  Plan  for  certain
employees  and  members  of  the  Board.  The  Deferred
Compensation  Plan  permits  eligible  participants  to  defer
receipt of compensation pursuant to the terms of the plan. The
Deferred  Compensation  Plan  permits  participants 
to
contribute, on a pre-tax basis, up to 75% of their base salary
earnings, up to 100% of their bonus pay and commissions and
up  to  100%  of  directors’  annual  retainer  earned  in  the
upcoming  plan  year.  We  provide  no  matching  or  other
additional contributions to such Deferred Compensation Plan.
Plan participants may designate investments for deferral in a
variety of different deemed investment options. To preserve
the  tax-deferred  status  of  deferred  compensation  plans,  the
IRS  requires  that  the  available  investment  alternatives  be
‘‘deemed 
investments.’’  Participants  do  not  have  an
ownership interest in the funds they select; the funds are only
used to measure the gains or losses that are attributed to the
participant’s deferral account over time.

Compensation Discussion and Analysis

subject to various participation limitations. As employees, our
NEOs are eligible to participate in this plan.

Severance and Change of Control Arrangements
Our  Change  of  Control  Severance  Plan  (the  ‘‘Change  of
Control  Plan’’)  provides  certain  benefits  in  the  event  of  a
change of control of Coherent for certain executives, including
each of our NEOs. Benefits are provided if there is a change in
ownership  of  Coherent,  a  change  in  effective  control  of
Coherent, or a change in ownership of a substantial portion of
Coherent’s  assets  (in  each  case  as  construed  under
Section  409A  of  the  Internal  Revenue  Code  and  the
regulations thereunder) (a ‘‘change of control’’) and within two
years  thereafter  (or  within  two  months  prior  thereto)  the
participant’s  employment  is  terminated  without  cause  or
voluntarily  terminates  following  a  constructive  termination
event.  The  plan’s  provisions  are,  therefore,  of  the  variety
commonly  referred  to  as  ‘‘double-trigger.’’  Importantly,  the
plan  does  not  include  any  ‘‘gross  up’’  provisions  for  the
participants for the tax effects caused by any such benefits.
The committee believes the Change of Control Plan serves as
an important retention tool in the event of a pending change of
control transaction.

The committee completed its review of the provisions of the
Change of Control Plan during fiscal 2015 and determined to
review the plan again in four years. In the first quarter of fiscal
2019, the committee reviewed and adopted substantially the
same Change of Control Plan and determined to review the
plan again in four years. Compensia assisted the committee in
its  review  and  analysis  of  the  Change  of  Control  Plan.  The
committee believes that reviewing the Change of Control Plan
every  four  years  allows  for  the  right  balance  in  providing
certainty  for  the  participants  while  providing  the  committee
with  the  opportunity  to  revise  the  plan  consistent  with
corporate  governance  best  practices,  evolving  peer  group
practices and regulatory changes.

The committee considers the Deferred Compensation Plan to
be  a  reasonable  and  appropriate  program  because  it
promotes  executive  officer  retention  by  offering  a  deferred
compensation plan that is comparable to and competitive with
what is offered by our peer group of companies.

The committee does not consider the potential payments and
benefits  under 
these  arrangements  when  making
compensation decisions for our NEOs. These arrangements
serve specific purposes unrelated to the determination of the
NEOs’ total direct compensation for a specific year.

Tax and Accounting Considerations

requirements  of  ASC  718.  We  also  take  into  consideration
ASC 718 and other generally accepted accounting principles
in determining changes to policies and practices for our stock-
based compensation programs.

in  accordance  with 

the 

income 

limits  our 

Internal  Revenue  Code—
Section  162(m)  of 
Section  162(m) 
tax  deduction  of
compensation  for  certain  executive  officers  unless  the
compensation is less than $1 million during any fiscal year or
certain performance-based compensation deductible in fiscal
years  before  fiscal  year  2019  or  certain  grandfathered
payments  pursuant  to  written  binding  contracts  in  effect  on
November 2, 2017. Although the committee may consider the
impact of Section 162(m) as well as other tax and accounting
consequences when developing and implementing executive
compensation programs, the committee retains the flexibility
to design and administer compensation programs it believes

are appropriate and in the best interests of the stockholders
after  taking  various  factors  into  consideration,  including
business conditions and the performance of the Company and
the executive officer. In addition, due to the ambiguities and
uncertainties  as  to  the  application  and  interpretation  of
Section  162(m),  including  with  respect  to  grandfathered
payments, as well as operational issues, no assurances can
be  given  that  compensation,  even  if  intended  to  satisfy  the
requirements for deductibility under Section 162(m), would in
fact do so. The tax legislation signed into law in late 2017 may
have additional impacts regarding the application of this and
other Internal Revenue Code provisions.

Section  409A  of  the  Internal  Revenue  Code—Section  409A
imposes  additional  significant  taxes  in  the  event  that  an
executive  officer,  director  or  service  provider  received
‘‘deferred  compensation’’ 
the
requirements of Section 409A. We consider Section 409A in
the design and operation of any plans.

that  does  not  satisfy 

Other Compensation Policies
To further align our executive compensation program with the
interests  of  our  stockholders,  at  the  end  of  fiscal  2009,  a
committee  of  the  Board  approved  a  clawback  policy  for  our
Chief  Executive  Officer  and  Chief  Financial  Officer.  The
clawback  policy  provides  that,  in  the  event  that  there  is  an
accounting  restatement  and  there  is  a  finding  by  the  Board
that such restatement was due to the gross recklessness or
intentional misconduct of the Chief Executive Officer or Chief

Financial Officer and it caused material noncompliance with
any financial reporting requirement, then Coherent shall seek
disgorgement of any portion of the bonus or other incentive or
equity  based  compensation  related  to  such  accounting
restatement received by such individual during the 12-month
period following the originally filed financial document. Under
our  Insider  Trading  Policy,  no  employees  or  directors  are
allowed to hedge or pledge Coherent securities.

Compensation Committee Interlocks and Insider Participation
During fiscal 2018, the Compensation and H.R. Committee of the Board consisted of Messrs. Vij (Chair), Flatley and Krause.
None of the members of the committee has been or is an officer or employee of Coherent. None of our executive officers serve on
the  board  of  directors  or  compensation  committee  of  a  company  that  has  an  executive  officer  that  serves  on  our  Board  or
Compensation and H.R. Committee. No member of our Board is an executive officer of a company in which one of our executive
officers serves as a member of the board of directors or compensation committee of that company.

Committee Independence
Each of the members of the committee qualifies as (i) an ‘‘independent director’’ under the requirements of The Nasdaq Stock
Market, (ii) a ‘‘non-employee director’’ under Rule 16b-3 of the Securities Exchange Act of 1934 (the ‘‘1934 Act’’), (iii) an ‘‘outside
director’’ under Section 162(m) of the Code and (iv) an ‘‘independent outside director’’ as that term is defined by ISS.

Compensation Discussion and Analysis

Compensation and H.R. Committee Report
The Compensation and H.R. Committee of the Board has reviewed and discussed the Compensation Discussion and Analysis
required by Item 402(b) of Regulation S-K with management and, based on such review and discussions, the Compensation and
H.R. Committee recommended to the Board that the Compensation Discussion and Analysis be included in this proxy statement.

Failure to meet a minimum level of performance would have resulted in no bonus paid out under the 2018 Variable Compensation Plan.

(2) Reflects the amount earned under the 2018 Variable Compensation Plan during fiscal 2018.

(3) Reflects the dollar amount recognized for financial statement reporting purposes (disregarding an estimate of forfeitures related to service-based vesting

conditions) for fiscal 2018 in accordance with ASC 718, and includes grants made in fiscal 2018. The assumptions used in the valuation of these awards are set

forth in Note 12 ‘‘Employee Stock Award and Benefit Plans’’ of the Notes to the Consolidated Financial Statements in our annual report on Form 10-K for fiscal

2018. For informational purposes, if the maximum level of performance for the PRSU awards was achieved, the value, calculated by multiplying the closing

price of the Company’s common stock on the date of grant by the number of shares issuable upon achievement of the maximum level of performance under the

applicable  PRSU  is  $9,766,434,  $1,301,949,  $1,215,152,  $1,085,217  and  $954,762,  for  Messrs.  Ambroseo,  Palatnik,  Sobey,  Sechrist  and  DiMarco,

(1) Generally, time-based RSU grants vest 1⁄3 per year on each anniversary of the grant date. For fiscal year 2017, in recognition of the integration efforts

associated with the acquisition of Rofin, additional time-based RSUs were granted on November 15, 2016 with a single vesting date one year from

the grant date with respect to 1,049, 928 and 891 shares to Messrs. Palatnik, Sechrist and DiMarco, respectively.

(2) Market value is determined by multiplying the number of shares by $172.19, the closing price of our common stock on September 28, 2018, the last

trading date of fiscal 2018.

(3) The performance-based RSU vesting determination date is November 3, 2020. The performance-based RSUs will vest in an amount which is

0-200% subject to the achievement of certain performance metrics. The amount reflected in the table is the maximum amount or 200%.

(4) The performance-based RSU vesting determination date is November 15, 2019. The performance-based RSUs will vest in an amount which is

0-200% subject to the achievement of certain performance metrics. The amount reflected in the table is the maximum amount or 200%.

(5) The performance-based RSU vesting determination date was November 13, 2018. The performance-based RSUs vested at 200% based on the

Potential Payments upon Termination
or Change of Control

The following table shows the potential payments and benefits
that  we  (or  our  successor)  would  be  obligated  to  make  or
provide  upon  termination  of  employment  of  each  our  NEOs
pursuant  to  the  terms  of  the  Change  of  Control  Severance
Plan.  Other  than  this  plan,  there  are  no  other  executive
employment  agreements  or  other  contractual  obligations
triggered upon a change of control. For purposes of this table,
it is assumed that each NEO’s employment terminated at the
close  of  business  on  September  29,  2018  (the  last  trading
date of fiscal 2018). These payments are conditioned upon the
execution of a form release of claims by the NEO in favor of us.
The amounts reported below do not include the nonqualified
deferred compensation distributions that would be made to the

Summary Compensation and Equity Tables

NEOs  following  a  termination  of  employment  (for  those
amounts and descriptions, see the prior table). There can be
no assurance that a triggering event would produce the same
or  similar  results  as  those  estimated  below  if  such  event
occurs on any other date or at any other price, of if any other
assumption used to estimate potential payments and benefits
is  not  correct.  Due  to  the  number  of  factors  that  affect  the
nature and amount of any potential payments or benefits, any
actual  payments  and  benefits  may  be  different.  These  are
aggregate payments and do not reflect such individual’s net
after  tax  benefit.  No  officer  is  entitled  to  any  ‘‘gross  up’’  to
offset the impact of IRS Code Section 280G.

Summary Compensation and Equity Tables

(2) Equity Compensation Acceleration represents the in-the-money value of unvested stock options, time-based restricted
stock units and performance-based restricted stock units, in each case as of September 28, 2018 (the last trading date
before the end of our fiscal year) at the closing stock price on that date ($172.19). The value of accelerated stock options is
calculated by multiplying the number of unvested shares subject to acceleration by the difference between the exercise
price and the closing stock price on September 28, 2018; and the value of accelerated restricted stock units is calculated by
multiplying the number of unvested shares subject to acceleration by the closing stock price on September 28, 2018. This
assumes immediate release and vesting of the performance-based restricted stock units at the maximum, or 200% of
target, achievement. The amounts reflected for Equity Compensation Acceleration do not reflect any applicable taxes, just
gross proceeds. Since the table assumes a triggering event on September 28, 2018, only those stock options and restricted
stock units outstanding as of that date are included in the table.

(3) Aggregate Healthcare Related Monthly Payment is a monthly payment of $2,750 in lieu of receiving Company-subsidized
COBRA benefits, life insurance premiums and/or other welfare benefits, multiplied by 36 months for our Chief Executive
Officer and 24 months for our other NEOs.

PAY RATIO

As  provided  for  by  the  Dodd-Frank  Wall  Street  Reform  and  Consumer  Protection  Act,  the  SEC  adopted  a  rule  requiring
companies to disclose the ratio of the median employee’s total annual compensation relative to total annual compensation of the
CEO. As disclosed in the ‘‘Summary Compensation Table’’ above, the fiscal 2018 total annual compensation for our CEO was
$9,531,892. We estimate that the fiscal 2018 total annual compensation for the median of all employees, excluding our CEO, was
$64,707. The resulting ratio of our CEO’s total annual compensation to that of the median of all employees, excluding our CEO,
for fiscal 2018 is approximately 147 to 1.

We identified the median employee by (i) aggregating for each employee employed on September 29, 2018 (our fiscal year end)
(A) annual base salary for salaried employees (or hourly rate multiplied by estimated work schedule, for hourly and seasonal
employees) and (B) target incentive compensation, (ii) converting amounts from local currency to U.S. dollars and (iii) ranking this
compensation measure for our employees other than our CEO from lowest to highest. Because we had an even number of
employees  (excluding  our  CEO)  on  the  determination  date,  two  employees  were  identified  as  the  median  compensated
employees. We reviewed the compensation of these two employees as well as the compensation of five employees immediately
above  and  below,  to  further  analyze  employee  median  compensation  for  consistency  with  that  of  other  employees  near  the
median. For these twelve employees, we calculated total annual compensation for such employees using the same methodology
used to calculate the ‘‘Total’’ column of the ‘‘Summary Compensation Table.’’ We then selected from among the two median
compensated employees, a United States employee whose compensation was most consistent with that of the twelve employees
reviewed.

The pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on our internal
records and the methodology described above. The SEC rules for identifying the median compensated employee and calculating
the pay ratio based on that employee’s total annual compensation allow companies to adopt a variety of methodologies, to apply
certain  exclusions,  and  to  make  reasonable  estimates  and  assumptions  that  reflect  their  employee  populations  and
compensation practices. Therefore, the pay ratio reported by other companies may not be comparable to the pay ratio reported
above,  as  other  companies  have  different  employee  populations  and  compensation  practices  and  may  utilize  different
methodologies, exclusions, estimates, and assumptions in calculating their own pay ratios.

CERTAIN RELATIONSHIPS AND RELATED PERSON
TRANSACTIONS

Review, Approval or Ratification of Related Person Transactions
In  accordance  with  the  charter  of  the  Audit  Committee,  the  members  of  the  Audit  Committee,  all  of  whom  are  independent
directors, review and approve in advance any proposed related person transactions. Additionally, from time to time the Board may
directly consider these transactions. For purposes of these procedures, the individuals and entities that are considered ‘‘related
persons’’ include:

• Any of our directors, nominees for director and executive officers;

• Any person known to be the beneficial owner of five percent or more of our common stock (a ‘‘5% Stockholder’’); and

• Any immediate family member, as defined in Item 404(a) of Regulation S-K, of a director, nominee for director, executive officer
and 5% Stockholder. We will report all such material related person transactions under applicable accounting rules, federal
securities laws and SEC rules and regulations.

Related Person Transactions
We  have  entered  into  indemnification  agreements  with  each  of  our  executive  officers  and  directors.  Such  indemnification
agreements require us to indemnify these individuals to the fullest extent permitted by law. We also intend to execute these
agreements with our future directors and officers.

REPORT OF THE AUDIT COMMITTEE OF THE
BOARD OF DIRECTORS

The  Audit  Committee  is  responsible  for  overseeing  our
accounting and financial reporting processes and audits of our
financial  statements,  including  reviewing  and  approving  the
fees  for  the  performance  of  the  audit  by  our  independent
auditors. As set forth in its charter, the Audit Committee acts
only  in  an  oversight  capacity  and  relies  on  the  work  and
assurances  of  both  management,  which  has  primary
responsibilities  for  our  financial  statements  and  reports,  as
well as the independent registered public accounting firm that
is responsible for expressing an opinion on the conformity of
our  audited  financial  statements  to  generally  accepted
accounting principles.

The Audit Committee met twelve (12) times either in person or
by  telephone  during  fiscal  2018.  In  the  course  of  these
meetings,  the  Audit  Committee  met  with  management,  the
internal  auditors  and  our  independent  registered  public
accounting firm and reviewed the results of the internal and
external  audit  examinations,  evaluations  of  our  internal
controls and the overall quality of our financial reporting.

the 

internal  auditors  and 

The Audit Committee believes that a candid, substantive and
focused  dialogue  with 
the
independent registered public accounting firm is fundamental
to the Audit Committee’s oversight responsibilities. To support
this belief, the Audit Committee periodically meets separately
with  the  internal  auditors  and  the  independent  auditors,
without management present. In the course of its discussions
in  these  meetings,  the  Audit  Committee  asked  a  number  of
questions  intended  to  bring  to  light  any  areas  of  potential
concern related to our financial reporting and internal controls.
These questions include:

• Are there any significant accounting judgments, estimates
or  adjustments  made  by  management  in  preparing  the
financial statements that would have been made differently
had 
themselves  prepared  and  been
responsible for the financial statements;

the  auditors 

• Based on the auditors’ experience, and their knowledge of
our business, do our financial statements fairly present to
investors,  with  clarity  and  completeness,  our  financial
position  and  performance  for  the  reporting  period  in
accordance with generally accepted accounting principles
and SEC disclosure requirements;

• Based on the auditors’ experience, and their knowledge of
our  business,  have  we  implemented  internal  controls  and
internal  audit  procedures  that  are  appropriate  for  our
business.

The Audit Committee approved the engagement of Deloitte &
Touche LLP as our independent registered public accounting
firm for fiscal 2018, including the fees to be paid for their audit
work, and reviewed with the internal auditors and independent
registered public accounting firm their respective overall audit
scope  and  plans.  In  approving  Deloitte  &  Touche  LLP,  the
Audit  Committee  considered  the  qualifications  of  Deloitte  &
Touche LLP and discussed with Deloitte & Touche LLP their
independence, including a review of the audit and non-audit
services provided by them to us. The Audit Committee also
discussed with Deloitte & Touche LLP the matters required to
be discussed by Auditing Standard No. 16, ‘‘Communications
with  Audit  Committees’’  issued  by  the  Public  Company
Oversight  Board  (PCAOB),  and  it  received  the  written
disclosures and the letter from Deloitte & Touche LLP required
by  the  applicable  requirements  of  the  Public  Company
Accounting  Oversight  Board 
regarding  Deloitte  &
Touche  LLP’s  communications  with  the  Audit  Committee
concerning independence.

the 

reporting, 

Management  has  reviewed  and  discussed  the  audited
financial statements for fiscal 2018 with the Audit Committee,
including a discussion of the quality and acceptability of the
financial 
reasonableness  of  significant
accounting  judgments  and  estimates  and  the  clarity  of
disclosures in the financial statements. In connection with this
review and discussion, the Audit Committee asked a number
of  follow-up  questions  of  management  and  the  independent
registered  public  accounting  firm  to  help  give  the  Audit
Committee comfort in connection with its review.

In reliance on the reviews and discussions referred to above,
the  Audit  Committee  recommended  to  the  Board  that  the
audited financial statements be included in the annual report
on Form 10-K for the fiscal year ended September 29, 2018,
for filing with the SEC.

Respectfully submitted by the Audit Committee.

ITEM  1. BUSINESS

GENERAL

Business  Overview

Our fiscal year ends on the Saturday  closest to September 30. Fiscal years 2018,  2017 and 2016
ended on September 29, September 30,  and October 1, respectively,  and are referred  to  in this annual
report as fiscal 2018, fiscal 2017 and fiscal 2016  for convenience. Each of  fiscal 2018,  2017 and  2016
included 52 weeks.

We  are one of the  world’s leading providers  of lasers, laser-based  technologies and laser-based

system solutions in a broad range of commercial, industrial and scientific applications. We  design,
manufacture, service and market lasers  and related  accessories  for a diverse group  of  customers.  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 medical applications, as well as in scientific research. Our ILS business segment  delivers
high performance laser sources, sub-systems and  tools primarily used for  industrial laser materials
processing, serving important end markets like automotive, machine tool, consumer goods and  medical
device manufacturing.

Income from continuing operations is the measure of profit and loss that our CODM uses  to
assess performance and make decisions.  Income  from continuing operations represents the  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 to our operating
segments certain operating expenses, which we  manage separately at the corporate level. These
unallocated costs include stock-based compensation and corporate functions (certain advanced research
and development, 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.

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

On March 8, 2018, we acquired privately held O.R.  Lasertechnologie  GmbH and  certain assets of
its  U.S.-based affiliate (collectively ‘‘OR  Laser’’) for approximately $47.4 million, excluding transaction
costs. OR Laser produces laser-based material processing equipment for a variety of uses, including
additive manufacturing, welding, cladding, marking,  engraving  and drilling. See  Note 3,  ‘‘Business
Combinations’’ in the Notes to Consolidated  Financial Statements under Item  15 of this annual  report.

On February 6, 2018, our board of directors authorized a stock repurchase  program authorizing

the Company to repurchase up to $100.0 million of  our common  stock  from time to time  through
January 31, 2019. During the three and nine months ended June 30, 2018,  we repurchased and  retired
574,946 shares of outstanding common  stock  under this program at an average price  of $173.91 per
share for a total of $100.0 million.

During  fiscal 2018, we made payments on our  senior secured term  loan facility (‘‘Euro  Term
Loan’’) of a total of 141.7 million Euros,  including voluntary payments of a  total of 135.0 million
Euros.

On November 7, 2016, we completed  our  acquisition of Rofin Sinar Technologies, Inc.  (‘‘Rofin’’)

pursuant to the Merger Agreement dated  March 16, 2016.  Rofin was one of the world’s  leading
developers and manufacturers of high-performance  industrial laser  sources and laser-based solutions
and components. As a condition of the  acquisition, we were required to divest and  hold  separate
Rofin’s low power CO2 laser business based in Hull, United  Kingdom (the ‘‘Hull Business’’), and
reported this business separately as a discontinued operation  until its divestiture. We completed the
divestiture of the Hull Business on October  11, 2017,  after receiving approval for the terms of the sale
from the European Commission. On  April  27, 2018, we completed  the sale  of  several entities that we
acquired in our acquisition of Rofin. See Note  18, ‘‘Discontinued Operations and Sale of Assets Held
for Sale’’ in the Notes to Consolidated  Financial  Statements

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 cutting 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. Some lasers  can be used to create
ultrafast output—a series of pulses with pulse durations as  short as attoseconds  (10(cid:4)18 seconds).

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 tool, 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  technology because  it can
do the job faster, better or more economically  (e.g. sheet metal cutting). 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 flexible  OLED displays  found  in the  latest smart phones,  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 lasers, optics, laser beam  delivery 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-systems or ‘‘rails’’), and  for certain
applications and markets we have also  developed parts handling  and  automation to build complete
laser production systems or tools.

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:

• Leverage our technology portfolio and application engineering to  lead the  proliferation 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. We plan to utilize  our  expertise to increase our  market  share in the
mid to high power material processing applications.

• Streamline our manufacturing structure and  improve  our cost structure—We will focus on
optimizing the mix of products that we manufacture internally and externally. We will  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—We define adjusted EBITDA as operating income  adjusted for  depreciation, amortization,
stock-based compensation expense, major restructuring costs and certain other non-operating
income and expense items, such as costs related to our acquisition of Rofin. Key initiatives for
EBITDA improvements include utilization  of our Asian manufacturing locations, optimizing our
supply chain and continued leveraging of our infrastructure.

• Optimize our leadership position in existing markets—There are a number of markets where we
have historically been at the forefront of technological development  and product deployment

7

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 to further develop our  loyal customer base. We plan to
maintain our current customer relationships and 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.

Microelectronics

Nowhere is the trend towards miniaturization and higher performance more prevalent than in the

Microelectronics market where smart phones, tablets, personal computers  (‘‘PC’s’’),  televisions (‘‘TV’s’’)
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  support three major markets in the  microelectronics industry:  (1) flat panel display  (‘‘FPD’’)

manufacturing, (2) advanced packaging and  interconnects  (‘‘API’’) and (3) semiconductor front-end
(‘‘SEMI’’).

Microelectronics—flat panel display  manufacturing

The high-volume consumer market is  driving the production of  FPDs in applications such as
mobile phones, tablets, laptop computers, TVs and wearables. There are several types  of  established
and emerging displays based on quite  different  technologies, including liquid crystal (‘‘LCD’’)  and
organic light emitting diodes (‘‘OLED’’).  Each 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  (‘‘TFTs’’).  If this
silicon is polycrystalline as opposed to amorphous, the display  performance  is greatly enhanced. In the
past, these polysilicon layers could only  be  produced on expensive special glass at high temperatures.
However, excimer-based processes, such  as  excimer  laser annealing  (‘‘ELA’’) have allowed 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 excimer Vyper  laser and  Linebeam systems. These
systems deliver power ranges of 1200W to 3600W,  depending on the system, enabling a critical
manufacturing process step with Generation 4, 5, 5.5  and 6 substrates. These  systems are  integral to the
manufacturing process on all leading  LTPS-based smart phone  displays, with  the highest commercially
available pixel densities of greater than 300  pixels per inch (ppi), with the current trends going to even
higher  ppi (~500 ppi) for high end smart  phones, and hold the potential for deployment in  tablet,
laptop and OLED TV displays. Excimer based LTPS  is also enabling  flexible  OLED displays which
have recently undergone rapid growth as  they have been adopted  into  smart phones.

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 CO2 and Rapid series  ultrafast lasers are
used for cutting FPD films.

We  have developed a proprietary technology  for cutting of brittle materials  such as glass and
sapphire without debris and with zero kerf  called SMART CleaveTM, 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 CO2 and CO lasers are also used in other production

processes for FPDs. These processes include drilling, cutting, patterning, marking and yield
improvement.

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  to  improve  performance and lower
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 requiring 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 microvias in chip substrates  and in
both rigid and flexible PCBs. These microvias are tiny interconnects that are essential for  enabling
high-density circuitry commonly used  in  smart  phones, tablets  and advanced computing systems. Our
DIAMOND  CO2 and AVIA diode pumped solid state  (‘‘DPSS’’) lasers  are the lasers of choice in this

9

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.

Microelectronics—semiconductor  front-end

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 the presence of defects is only the first  step in  preventing their recurrence. After

detection, 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 and ion  lasers are  used to detect and
characterize defects in semiconductor chips.

Materials  processing

The materials processing segment is comprised of four major markets: (1)  automotive, (2) machine

tool, (3) medical device and (4) consumer goods,  as well a number of smaller markets. It  is the most
diverse of all the segments we serve  and  a large cross section of  our products are used  in this segment.
Our sales in this segment include laser sources, laser sources with beam  delivery optics (laser rails),
beam delivery components, laser diagnostic  equipment and complete  laser systems (tools). At a high
level,  the drivers for laser deployment within the  materials processing  segment are faster  processing
with higher yields,  processing of new and novel  materials, more environmentally friendly processes and
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 industry,  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. We serve this industry with a  number  of our  products including ultrafast,  DPSS,
CO2, diode and fiber lasers as well as rails and tools in the  areas  of  marking, scribing,  cutting and
welding.

In the machine tool industry lasers have  been the solution of choice for cutting metal for  some
time. Traditionally this was a market  for high power CO2 lasers, but with the advent of high power fiber
lasers, a transition  away from CO2 took place in many applications. That transition is substantially done
since fiber lasers are used in the majority of  metal cutting applications. We serve  this  market with our
high power fiber and CO2 lasers. As a fully vertically integrated fiber and laser diode  supplier,  we are
able to produce all key components in-house. We  have a complete  line of high  power  fiber lasers in
power levels up to 10 kW. We offer lasers with different performance points  in terms of  power  levels
and beam profiles to address specific  applications, including  single  mode  lasers and advanced beam
shaping options, e.g. the ARM advanced  high power fiber  laser where the beam parameters can be

10

optimized to reach higher quality welds  and translate into higher customer yields. Additive
manufacturing or 3D printing is another growing market where lasers have seen  rapid  growth. We  serve
this  market with laser selective laser  melting  (SLM)  systems for 3D printing  of  metal parts called Laser
Creator as well as CO2 and DPSS lasers.

The medical device 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 corrosive  resistant marking. We serve this  market with a number of
lasers as well as a portfolio of tools.

In the consumer goods market, we serve a large  variety of applications  in packaging, digital

printing, jewelry, textiles, security and  consumer electronics. We serve these industries with almost all of
our  products from lasers to laser tools.  As a  consequence, this  broad  segment represents a stable  and
growing market for us.

In summary, we serve the materials processing segment with a very broad  product portfolio. Laser

sources  include the Diamond series mid-power CO  and  CO2 lasers; the DC series of high power CO2
lasers; Highlight FL high power fiber lasers;  the DF  series  of high power  diode laser systems; the
Diamond mid-power and Q-Switched fiber; the COMPACT, MINI and EVOLUTION series of low  and
mid power diode lasers; the AViA, Matrix, Flare,  Helios and LDP DPSS lasers; the Monaco  and Rapid
series of ultrafast lasers; and the SLS, KLS, FLS  and  NA series of lamp  pumped lasers.  Laser tools
include the Performance, Select and  Integral series of manual  welding systems; the  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. Laser rails, 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
PerfoLas and StarShape CO2 laser  based systems.

OEM components and instrumentation

Instrumentation is one of our more mature commercial applications. Representative  applications
within this market include bio-instrumentation,  medical  OEMs, graphic arts and display, machine  vision
and defense applications. We also support the laser-based  instrumentation  market  with a range  of laser-
related components, including diode  lasers  and  optical fibers. Our OEM component business includes
sales to other, less integrated laser manufacturers participating in  OEM markets such  as materials
processing, scientific, and medical.

Bio-instrumentation

Laser applications for bio-instrumentation include bio-agent detection  for  point source and
standoff detection of pathogens or other bio-toxins; 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;  and  flow cytometry for analyzing
single cells or populations of cells in  a  heterogeneous mixture,  including blood  samples. Our OBIS,
Flare, Galaxy, Sapphire, BioRay and Genesis lasers  are used in several bio-instrumentation
applications.

Medical Therapy

We  sell a variety of components and lasers  to  medical  laser companies  for use in end-user
applications such as ophthalmology, aesthetic,  surgical, therapeutic  and dentistry. Our  DIAMOND

11

series CO2 lasers are widely used in ophthalmic, 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.

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. The 577nm wavelength was designed to match the peak in  absorption of
oxygenated hemoglobin thereby allowing  treatment to occur  at  a  lower  power level, and  thus reducing
stress and heat-load placed on the eye with traditional  green-based  (530nm)  solid  state lasers. 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 research and government programs

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 gas lasers  and water-cooled  ion gas  lasers. Our
portfolio of lasers that address the scientific research market is broad and includes  our  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, physical chemistry and physics. Most 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(cid:4)15 to 10(cid:4)18 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 generate many exotic effects. 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.

FUTURE  TRENDS

Microelectronics

Lasers  are widely used in mass production microelectronics applications largely because they
enable entirely new application capabilities that cannot  be  realized by  any other  known  means. These
laser-based fabrication and testing methods provide  a level  of precision, typically  on a  micrometer and
nanometer level, that are unique, faster, are touch free,  deliver superior end products, increase  yields,
and/or reduce production costs. We anticipate this trend  to continue, driven  primarily by the  increasing
sophistication and  miniaturization of consumer electronic  goods and their  convergence  via the  internet,
resulting in increasing demand for better  displays, more bandwidth and memory, and  all  packaged into
devices which are lighter, thinner and consume less  power. Although this market follows the macro-
economic trends and carries inherent  risks,  we believe  that we are well  positioned to continue  to
capitalize on the current market trends.

Excimer laser based LTPS is a key technology for producing high  resolution  OLED displays in

general and flexible OLED displays in particular.

12

Demand  for CO2, Avia, Matrix, Rapid, Monaco, Helios  and  direct  diode  lasers correlate with the

need for related FPD touch panel, film 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,  CO2, Monaco and Rapid lasers
together with our proprietary SmartCleave technology are well  positioned to take advantage of this
trend.

Semiconductor devices look set to continue Moore’s Law, shrinking device geometries  for at least

another decade, as well as expanding  vertically into new 3D  structures. As a result we believe our  many
UV laser sources (such as Azure, Paladin, Avia, Rapid, ExiStar and  Matrix) will continue to find
increasing adoption, since their unique  optical properties align well  with the  process  demands of a
nanometer scale world.

These same lasers, plus Monaco, Rapid, CO and CO2 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 &  LED  scribe widths  and wafer thickness,  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.

While we anticipate investment in OLED technology to continue, we  expect  a softening of the

demand in fiscal 2019 and a recovery from anticipated 2019 demand levels  in fiscal 2020, with
additional vendors supplying OLED displays  for consumer products.

Materials  processing

The materials processing segment is the most diverse  of  all the segments  we serve  and a  large
cross section of our products are used in this segment. We sell laser sources, laser  rails,  beam delivery
components, laser diagnostic equipment and complete laser  tools.  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 reduction in emissions  from lighter cars and  electric vehicles require new
materials and 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 CO2
lasers. For example, the trend toward lighter  weight cars requires more  aluminum welding, an
application in which our ARM laser technology offers competitive advantages versus alternative
solutions. We see similar opportunities for electric vehicle  and  battery applications.

We  expect to see continued growth for  high power fiber lasers  in the  machine tool industry used in

metal cutting applications. In addition,  we  see additional opportunities in  newer applications  such as
laser cladding and heat treatment.

In the consumer goods market, we serve a large  variety of applications  in packaging, digital

printing, jewelry, textiles, security and  consumer electronics. We serve these industries with almost all of
our  products from lasers to laser tools.  As a  consequence, this  broad  segment represents a stable  and
growing market for us.

We  supply the medical device market  with a variety of lasers  and laser tools in  applications  such as

fine cutting and welding as well as marking. This market is set to continue to grow in  the foreseeable

13

future as the population becomes older and advanced  medical  procedures  spread outside the traditional
markets in US, Europe and Japan.

In 3D printing we expect continued growth, particularly  in the area of metal additive

manufacturing where we supply SLM  tools.

OEM components and instrumentation

The bio instrumentation market’s most important areas: microscopy, flow  cytometry and DNA
sequencing, are all enjoying solid research funding 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 has resulted in growth for us in  this market  and we expect  that  to  continue. Our
OPSL technology resulted in the first truly continuous wave solid-state UV laser which enables the  use
of UV in a clinical as well as a research  environment.

In the medical therapeutic 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 including the use of ultrafast lasers in applications  such as  laser cataract surgery
where  higher precision and use of advanced implants enable better and more reliable  patient  outcomes.
We  also have opportunities in dental  procedures for both hard and  soft tissue ablation, with greatly
improved patient comfort and outcome.  In  the area of  photocoagulation, 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 CO2 and semiconductor lasers to the major manufacturers of equipment used
in the latest aesthetic procedures.

Scientific research and government programs

Worldwide scientific funding is expected to be relatively stable,  with some regions  growing  and

others just holding their current level.  Bright spots  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 in animal brains  using techniques such  as optogenetics.  We  believe that our
current and upcoming products are well positioned to take advantage  of this exciting  opportunity. 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.

In addition to 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 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 types of  DPSS  lasers for different applications including
semiconductor inspection; advanced packaging  and  interconnects; laser  pumping; spectroscopy;
bio-agent detection; DNA sequencing; drug discovery;  flow cytometry; forensics; computer-to-plate
printing; 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 fiber laser design has several  unique  features including a modular design  for improved
serviceability and diode bar based pumping. Due to packaging  efficiency,  diode bars  reduce the overall
cost of a fiber laser. Some of the most critical components inside a fiber laser include the gain  fiber
itself and the diodes providing the pump  power. We plan to continue to drive cost reduction in our
diode laser pumps and demonstrate the  scalability of the platform  and as  a result, expect to be well
positioned as a fiber laser supplier. This  platform addresses the large growing high  power  metal cutting
and joining market.

We  are the world’s leading OEM supplier 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  and OEM
Medical Fiber Assemblies. We produce our Medical assemblies  in high volume in one of  our ISO 13485
certified plants. In addition, many of  the fiber components offered in  the broader  market,  such as Fiber
Bragg Gratings and Fiber Combiners, have  Coherent fiber in  them.

Gas lasers (CO, CO2, Excimer, Ion)

The breadth of our gas laser portfolio is industry  leading, encompassing CO, CO2, excimer and ion
laser technologies. Gas lasers derive their name from the  use of one or more gases as a  lasing medium.
They collectively span an extremely diverse  and  useful emission range, from  the very deep ultraviolet to

16

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, medical therapeutic and materials processing applications.

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, medical 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, military and
industrial applications, including aesthetic (hair removal,  cosmetic dentistry), graphic arts,  counter
measures, rangefinders, target designators,  cladding, hardening, brazing  and welding.

Ultrafast  (‘‘UF’’) Lasers

Ultrafast  lasers are lasers generating light pulses with  durations  of  a  few femtoseconds
(10(cid:4)15 seconds) to a few tens of picoseconds  (10(cid:4)12 seconds). These types of 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.

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 has  been
growing rapidly over the last several years, particularly in  microelectronics and  materials processing
applications.

Integrated Laser Solutions: Rails and Tools

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  tool
the laser is typically combined with delivery  optics and beam steering devices, such as galvos, to deliver

17

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’ or ‘rails’ 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. Rail
products often include vision systems, process monitoring  and monitoring of the system itself.  Our rail
products include: PowerLine series for  marking; the  StarFiber for welding  and cutting; the PWS
welding system; the QFS laser scribing  system; and the PerfoLas and  StarShape  CO2 laser based
systems.

In select cases we  also offer complete laser systems or ‘tools’ which include the  laser rail  as well as

a material handling system inside a class  1 laser safety  housing, ready to be used in production  or
development environments. Our laser tools products  include: the  Laser  Creator 3D metal printing
system; the Performance, Select and Integral series of manual welding systems; the Exact 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, France, Israel, Germany, Italy, Japan,
the Netherlands, China, South Korea, Taiwan, Singapore, Spain 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 and other European and
Asia-Pacific countries. Foreign sales accounted for 84% of our net  sales in fiscal 2018, 83% of our net
sales in fiscal 2017 and 76% of our net  sales in fiscal 2016. 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 fiscal 2018, 2017 and 2016.  We  had another major customer, Japanese Steel
Works, Ltd., who contributed more than 10% of revenue during fiscal 2016.

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 field service  staff  in major  markets within the United States,
Europe, Japan, China, South Korea, Taiwan 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 months.

MANUFACTURING

Since the acquisition of Rofin in November 2016, we have  integrated  Rofin into our organizational

structure and both organizations are  operating as one company with common objectives, goals and
processes. Strategies are being implemented to improve operating leverage, to execute  synergies and to
enhance our customers’ experience. Common policies and guidelines have been communicated,  key
management and operating processes have been implemented and ERP systems at all of Rofin’s sites in
Asia and North America, and certain  sites in Europe,  have been  integrated onto our Oracle  ERP and
Agile planning platforms, consistent with  the rest of Coherent. This integration process will continue
into fiscal 2019.

Strategies

One  of our core manufacturing strategies is to tightly  control our  supply of key parts, components,

sub-assemblies and outsourcing partners.  We  primarily 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 provide  customers with products  manufactured at the highest  level
of quality, leveraging Coherent’s quality  processes that are International Organization  for
Standardization (‘‘ISO’’) certified at  our  principal  manufacturing  sites.

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 have transferred the production of additional products  into  both
of our Singapore and Malaysia factories. With the acquisition of Rofin, we now have  a manufacturing
footprint in Nanjing, China. We are transferring additional products and volume to Nanjing as  well as
consolidating our China repair activities  in that facility. We have significantly increased our tube
refurbishment capacity and footprint in our South Korea operations, which  has allowed us to reduce
service response time and inventories,  providing benefits to us  and to our  customers. We have also
increased our sourcing of materials from  Asia through our  International  Procurement  Office in
Singapore, which has enabled us to 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, both internal  and
external, for some of our key components  and  materials, including  exotic  materials, certain cutting-edge
optics and crystals, used in our products,  which make us susceptible to supply shortages or price

19

fluctuations that could adversely affect  our business, particularly our  ability  to  meet our  customers’
delivery  requirements.’’

second  quarter of fiscal 2018, we acquired OR  Laser and we manufacture  and test the laser tools for
the Metal Additive Manufacturing (3D  Printing) market in  Dieburg, Germany.

We  have transferred several products  and subassemblies  for manufacture  and repairs to our
Singapore, Malaysia and Nanjing, China  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 recognized  manufacturing standards. All  of  our

legacy Coherent facilities are ISO 9001  certified and several facilities  are ISO  13485, ISO 14001,
ISO 17025 and/or ISO 50001 certified depending on the products  designed and manufactured  at that
facility. Substantially all of our legacy  Rofin  facilities are either ISO 9001 certified or are  in the process
of being certified.

20

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  September 29, 2018, we held approximately
725 U.S. and foreign patents, which expire in  calendar  years 2018 through  2037 (depending on the
payment of maintenance fees) and we  have approximately 245 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 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. 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.

BACKLOG

At fiscal 2018 year-end, our backlog of orders scheduled for  shipment (within one year) was
$759.9 million compared to $1,040.0 million  at fiscal 2017 year-end. By segment, backlog for  OLS was
$488.8 million and $801.4 million, respectively,  at fiscal 2018 and 2017  year-ends.  Backlog for  ILS was
$271.1 million and $238.6 million, respectively,  at fiscal 2018 and 2017  year-ends.  The  decrease in OLS
backlog from fiscal 2017 to fiscal 2018 year-end was primarily due to the  timing of large excimer laser
annealing system shipments, net of orders,  for the  flat panel display market. The  increase in ILS
backlog from fiscal 2017 to fiscal 2018 year-end was primarily from orders  in the materials processing
and high power fiber laser markets. 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.  Subsequent to year-end, one  customer indicated its intent to
cancel three purchase orders which included orders shippable within 12  months 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.

21

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%-12% 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

As of fiscal 2018 year-end, we had 5,418 employees.  Approximately  694 of our employees  are

involved in research and development;  3,496  of  our  employees are  involved in  operations,
manufacturing, service and quality assurance; and 1,228 of our 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.

ACQUISITIONS

On March 8, 2018, we acquired privately held OR  Laser  for approximately $47.4  million,  excluding

transaction costs. OR Laser produces laser-based material processing equipment for a variety of uses,
including additive manufacturing, welding, cladding, marking, engraving  and drilling.

On November 7, 2016, we acquired Rofin, one of the world’s leading  developers and

manufacturers of high-performance industrial laser sources and laser-based solutions and components,
for approximately $936.3 million. Rofin’s  operating  results have  been included primarily  in our
Industrial Lasers & Systems segment.

Please refer to Note 3, ‘‘Business Combinations’’ and  Note  19, ‘‘Subsequent Events’’ of Notes to

Consolidated Financial Statements under Item  15 of this annual report for further discussion of recent
acquisitions  completed.

RESTRUCTURINGS AND CONSOLIDATION

In the first quarter of fiscal 2017, we began the  implementation of planned restructuring activities

in connection with the acquisition of Rofin. These  activities to date  primarily  have related to exiting
our  legacy high power fiber laser product  line, change  of control payments to Rofin officers, the exiting
of two product lines acquired in the acquisition  of Rofin,  realignment of our supply chain  due  to
segment reorganization and consolidation  of sales  and  distribution offices  as well as  certain
manufacturing sites. These activities resulted  in charges primarily for  employee termination, other exit
related costs associated with the write-off of property and equipment and inventory and early  lease
termination  costs.

The fiscal 2018 severance related costs are primarily comprised  of severance  pay for  employees

being terminated due to the consolidation of certain manufacturing sites. The fiscal 2018 asset
write-offs are primarily comprised of inventory and  equipment write-offs due to the consolidation of
certain manufacturing sites.

We  plan to continue additional restructuring activities  in fiscal  2019 related to our acquisition of

Rofin.

GOVERNMENT REGULATION

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. Such rules are subject to change by the governing  agency  and we monitor those changes
closely. 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.

We  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. These regulations and standards have an impact on the material composition
of our products entering specific markets.  Such  legislation has gone into effect at various time across
the worldwide markets. For example,  in  the European Union  (‘‘EU’’),  the  Restriction  of  the use  of
Certain Hazardous Substances in Electrical and Electronic  Equipment (RoHS) went into effect in 2006,
and was subsequently revised in 2011 (as  RoHS  2) and again in 2015  (as RoHS 2 amended)  and will be
in effect in 2019. The Registration, Evaluation, Authorization and  Restriction of Chemicals (REACH)
went into effect in 2007, and is updated  with additional  substances every 6 months. China enacted the
Management Methods for Controlling Pollution  Caused by Electronic Information Products Regulation
(China-RoHS) in 2007, which was revised  and renamed in 2016  as the Administrative Measures for the
Restriction of the Use of Hazardous  Substances in  Electrical and Electronic  Products (known  as China
RoHS 2). Another example is the US Dodd-Frank Wall Street  Reform  and Consumer Protection Act of
2010 (Conflict Minerals Act) which requires manufacturers to provide disclosures about  the use of
specified conflict minerals emanating  from the DRC and nine adjoining countries (Covered Countries).
In addition to these regulations and  directives, we may  face costs and liabilities  in connection  with
product  take-back legislation. For example, beginning in  2006 (with several  subsequent revisions), the
EU Waste Electrical and Electronic Equipment Directive 2012/19/EU made producers of  electrical
goods financially responsible for specified  collection, recycling, recovery, treatment and disposal  of past
and future covered products. Similar  laws  are  now pending in various jurisdictions around  the world,
including the United States.

Environmental  liabilities

Our operations are subject to various laws  and  regulations governing  the environment,  including
the discharge of pollutants and the management and disposal  of hazardous substances. As a result of
our  historic as well as on-going operations,  we could incur substantial costs,  including remediation
costs. The costs under environmental laws and the timing  of these costs are  difficult  to  predict. Our
accruals for such costs and liabilities may  not be adequate because the estimates on  which the accruals
are based depend on a number of factors including  the nature of the matter, the  complexity of the site,
site geology, the nature and extent of  contamination, the type  of remedy, the outcome  of  discussions
with regulatory agencies and other Potentially  Responsible Parties (PRPs) at  multi-party sites  and the
number and financial viability of other PRPs.

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.

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 risk of our businesses 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.

Our operating results, including net sales,  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 our future operating  results will
continue  to be subject to quarterly and  annual fluctuations based upon numerous factors,  including those
discussed in this Item 1A and throughout this report. Our stock price  will continue to  be  subject to daily
variations as well. Our future operating results and stock  price may not follow any past trends or  meet our
guidance and expectations.

Our net  sales and  operating results, such as adjusted EBITDA percentage, net  income  (loss)  and

operating expenses, and 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;

• impact of government economic policies on macroeconomic conditions, 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;

• fluctuations in demand for our products or downturns in  the industries that we  serve;

• 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;

24

• 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;

• fluctuations in our product mix;

• the ability of our customers’ other  suppliers to provide  sufficient material to support our

customers’  products;

• currency fluctuations and stability, in particular the Euro, the  Japanese Yen,  the South Korean

Won, the Chinese RMB and the US dollar  as compared to other currencies;

• commodity pricing;

• interpretation and impact of the recently  enacted and aforementioned U.S.  tax law, the Tax Cuts

and Jobs  Act;

• introductions of new products and product  enhancements by  our competitors, entry of new

competitors into our markets, pricing pressures and other competitive factors;

• 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,  such as  the historical Rofin businesses,

into our operations and management;

• our ability to successfully internally  transfer  products as  part  of our  integration efforts;

• 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;

• seasonal sales trends, including with respect  to  Rofin’s  historical business,  which has  traditionally
experienced a reduction in sales during the  first  half  of  its  fiscal year  as compared  to  the second
half of its fiscal year;

• 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;

25

• 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;

• costs related to acquisitions of technology or businesses;

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

• our ability to meet our expectations and forecasts and those of public market analysts  and

investors;

• the availability of research funding by  governments with regard  to  our customers in the scientific

business, such as universities;

• continued government spending on  defense-related and scientific research  projects  where we are

a 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;

• 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;

• 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 ‘‘Brexit’’  vote by  the United Kingdom, particularly with regard to
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 the recent  independence movement in  Catalonia, Spain, particularly
with regard to holding and operating some of our foreign entities in an efficient manner from  a
tax, business and legal perspective;

• negative impacts related to government instability in any jurisdiction in  which we operate, such

as the recent difficulties in forming  a governing coalition in Germany;

• the future impact of legislation, rulemaking, and changes  in accounting, tax, defense

procurement, export policies; and

26

• 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, such as varying product mix, 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.  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,  used
in  our products, which make 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. In particular, from time-to-time  our  customers
require us to ramp up production and/or accelerate delivery schedules of  our products. 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  which may be
particularly susceptible to prevailing economic conditions. Some of our suppliers are located in regions
which  may be susceptible to natural disasters, such as the flooding in Thailand and  the earthquake,
tsunami and resulting nuclear disaster  in Japan and severe flooding and power  loss in  the Eastern part
of the United States in recent years. 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

27

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.

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.

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 our customers reschedule or cancel  orders.

In the flat panel display market, there are  a relatively limited number  of manufacturers who are
the end customers for our annealing  products. In fiscal 2018, 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, our customers may seek  to  reschedule  or cancel orders. For example,  in the fourth
quarter of fiscal 2018, a customer requested a  change of delivery date resulting in a significant order
being rescheduled from the first to the  second quarter of fiscal 2019. In addition, subsequent to
year-end, one customer indicated its  intent to cancel  three purchase orders which  included backlog
shippable within 12 months of $38.2 million as well as some additional  orders which were unscheduled.

28

These larger flat panel-related systems have large  average selling prices. 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 also 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.

As of September 29, 2018, flat panel  display systems  represented 32% of  our backlog, compared to

59% at September 30, 2017. Since our backlog includes higher  average  selling price flat panel  display
systems compared to other products in our  backlog, any delays or cancellation of shipments  could  have
a material adverse effect on our financial  results.

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

We  have devoted, and expect to continue to devote, significant  management attention and
resources to integrating our business  practices with  those of Rofin. Such 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 Rofin  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;  and

• the disruption of, or the loss of momentum in, our business or 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.
For example, in the fourth quarter of  fiscal 2018, difficulties in implementing our Enterprise
Management Systems at one of our manufacturing  sites located in  Germany, which  was  historically part
of Rofin, resulted in a shortage of manufacturing parts and shippable inventory  to  meet demands,
resulting in a reduction of revenue for the  quarter. If we are unable  to  timely resolve  these
implementation issues, or if similar difficulties  arise in the  future at another site,  we may in the future
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 the merger, the size and complexity of the  business of the combined  company has
increased significantly. Our future success  depends, in  part, upon our ability to manage this expanded
business, which has and will pose substantial challenges for management,  including challenges related  to

29

the management and monitoring of new operations  and associated  increased  costs and complexity.
There can be no assurances that we  will  be  successful or  that we will realize  the expected  synergies and
benefits anticipated from the merger.

Charges to earnings resulting from the  application of the purchase method of  accounting  to the Rofin
acquisition may adversely affect our results  of operations.

In accordance with generally accepted  accounting principles, we have accounted for the Rofin

acquisition using the purchase method of accounting. Under the purchase method  of  accounting, we
allocated the total purchase price of  Rofin’s net tangible and identifiable  intangible assets based upon
their estimated fair values at the acquisition date.  The  excess  of  the purchase price  over net tangible
and identifiable intangible assets was  recorded as goodwill. We have incurred  and will continue  to  incur
additional depreciation and amortization  expense  over the useful lives of  certain  of the net tangible and
intangible assets acquired in connection  with the acquisition. In addition, to the extent the  value of
goodwill or intangible assets with indefinite lives becomes impaired, we may  be  required to incur
material charges relating to the impairment of those assets. These depreciation,  amortization  and
potential impairment charges could have a material  impact  on our results of operations.

Our indebtedness following the 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 the Credit  Agreement which provided  for a  670 million Euro

term loan, all of which was drawn, and a  $100 million revolving credit  facility,  under which  a 10 million
Euro  letter of credit was issued. As of September  29, 2018, 371.6 million  Euros  were outstanding under
the term loan and 10.0 million Euros were  outstanding under the revolving credit  facility.  We  may incur
additional indebtedness in the future  by accessing the revolving credit  facility  and/or 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 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.

Our substantially increased indebtedness  and higher debt-to-equity ratio as a result  of  the 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

30

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.

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 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;

• 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, 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.

31

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.

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, 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 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. Current global economic conditions remain uncertain and challenging. Weakness in our end
markets could negatively impact our  net sales, gross  margin and  operating expenses, and consequently
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 recur, it  would likely
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

32

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 ‘‘Part II,  Item 9A. CONTROLS AND PROCEDURES.’’

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,
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 a  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.’’

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 (‘‘ASPs’’) 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 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 ASPs of some of our products. As  competing
products become more widely available,  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.

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.

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

For fiscal 2018, fiscal 2017 and fiscal  2016, 84%, 83%  and 76%, respectively,  of  our  net sales  were

derived from customers outside of the  United States. We anticipate that foreign  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 foreign
markets in which we operate, such as  the  earthquake, tsunami and resulting nuclear  disaster in Japan

34

and the flooding in Thailand in recent years. 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
foreign sales are primarily through our  direct sales force. Additionally,  some foreign  sales are made
through foreign distributors and representatives.  Our  foreign 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;

• unexpected changes in regulatory requirements;

• certification requirements;

• environmental regulations;

• reduced protection for intellectual property rights  in some  countries;

• potentially adverse tax consequences;

• political and economic instability;

• 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 pandemic  illness
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 foreign subsidiaries. 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.

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

35

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 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. 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;

• 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.

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.

36

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, 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.  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.

Our future success depends upon the continued services of  our executive officers  and other  key
engineering, sales, marketing, manufacturing and  support personnel,  any of  whom  may leave and our
ability to effectively transition to their  successors. Our  inability to retain or to effectively  transition  to
their successors could harm our business and our results of operations.

The long sales cycles for 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 Holdings Inc., MKS Instruments,  Inc., Novanta Inc., nLIGHT, Inc. 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. We may  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

37

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. Any of  these occurrences would  negatively impact our net sales,
business or operating results.

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

subassemblies 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 impact of worldwide economic  conditions, 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.

38

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 strategic acquisitions  of other corporations  and  entities, including  OR

Laser in March 2018 and Rofin in November  2016, as well  as asset  purchases,  and we continue to
evaluate  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 amortization.

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.

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;

39

• 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.

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.

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.

40

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 (‘‘REACH’’), the
Restriction on the Use of Certain Hazardous Substances in Electrical  and  Electronic Equipment
Directive (‘‘RoHS’’) and the Waste Electrical and Electronic  Equipment Directive (‘‘WEEE’’)  enacted
in the European Union, which regulate  the  use of certain  hazardous 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.

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, acts  of war, pandemic  illnesses, 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.

Difficulties with our enterprise resource planning  (‘‘ERP’’)  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

41

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.

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.

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 law, the Tax Cuts

and Jobs  Act (the ‘‘Tax Act’’);

• 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;

• the resolution of issues arising from tax audits with  various tax authorities, and in particular,  the
outcome of the German tax audits of Coherent and Rofin tax returns for fiscal 2010 -  2016;

• adjustments to estimated taxes upon finalization of various tax returns;

42

• 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;

• 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 (‘‘BEPS’’) action plan  implemented by the  Organization for Economic
Co-operation and Development (‘‘OECD’’); and

• changes in generally accepted accounting principles.

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 (‘‘IRS’’) 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 recent U.S.
tax law  changes are subject to further interpretations from the U.S. federal and  state governments and
regulatory organizations, such as the Treasury  Department  and/or the  Internal  Revenue Service.
Updated guidance and interpretations  could  change the provisional tax liabilities or  the accounting
treatment of them. We may pay the transition tax calculated under the  Tax Act over a  period of up to
eight  years.

Changing laws, regulations and standards relating  to corporate governance and public disclosure  may create
uncertainty  regarding  compliance  matters.

Federal securities laws, rules and regulations,  as well  as the rules and regulations of self-regulatory

organizations such as NASDAQ and the  NYSE,  require companies to maintain extensive corporate
governance measures, impose comprehensive reporting and disclosure  requirements, set  strict
independence and financial expertise standards  for audit and  other committee members and impose
civil and criminal penalties for companies and their chief executive officers,  chief financial officers and
directors for securities law violations.  These laws, rules and regulations have increased and will
continue to increase the scope, complexity and cost  of  our  corporate  governance,  reporting and
disclosure practices, which could harm our results of operations and divert management’s attention
from business operations. Changing laws,  regulations and standards relating to corporate governance
and public disclosure may create uncertainty regarding compliance matters. New or changed laws,
regulations and standards are subject  to  varying interpretations  in many cases. As  a result, their
application in practice may evolve over time. We  are committed to maintaining  high standards of  ethics,
corporate governance and public disclosure.  Complying with evolving  interpretations of new or changed
legal requirements may cause us to incur higher  costs as we revise current  practices, policies and
procedures, and may divert management  time  and  attention  from revenue generating to compliance
activities. If our efforts to comply with new  or changed  laws,  regulations and standards differ from  the

43

activities intended by regulatory or governing bodies due to ambiguities related to practice, our
reputation may also be harmed.

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 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 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.

The U.S. 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. 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  drop in export
demand for our Chinese customers particularly in the  materials  processing  space. As a result, 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), 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. For  example,  we were audited in South Korea for customs  duties
and value added tax for the period from March 2009 to March  2014. We  were liable  for additional
payments, duties, taxes and penalties of  $1.6 million, which we paid  in the second quarter of  fiscal
2016. 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.

In addition, compliance with the directives  of the Directorate  of Defense  Trade Controls

(‘‘DDTC’’) may result in substantial expenses  and diversion of management’s attention. Any failure  to
adequately address the directives of DDTC could result in civil fines or 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.

44

Failure to maintain effective internal controls may cause a loss of investor confidence in the  reliability of our
financial statements or to 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.

Provisions of our charter documents and Delaware law, and  our Change-of-Control 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 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.

We  consider our facilities to be both  suitable and adequate to provide for current and  near term

requirements and that the productive capacity in our  facilities is substantially being utilized or we have
plans to utilize it.

ITEM 3. LEGAL PROCEEDINGS

We  are subject to legal claims and litigation arising  in the ordinary course of business, such as
product  liability, employment or intellectual property claims, including, but not limited  to,  the matters
described below. On May 14, 2013, IMRA America (‘‘Imra’’)  filed a complaint for  patent  infringement
against two of our subsidiaries in the Regional Court of D¨usseldorf, Germany, captioned In re  IMRA

47

America Inc. versus Coherent Kaiserslautern GmbH  et.  al. 4b O  38/13. The complaint alleged that the
use of certain of the Company’s lasers infringed  upon EP Patent No.  754,103, entitled ‘‘Method For
Controlling Configuration of Laser Induced Breakdown  and  Ablation,’’ issued  November 5,  1997. The
patent, now expired in all jurisdictions, is owned  by  the University of Michigan  and licensed  to  Imra.
The complaint sought unspecified compensatory damages  and the  cost of court proceedings  and sought
to permanently enjoin the Company from infringing the patent in  the future.  Following the filing of the
infringement suit, our subsidiaries filed  a  separate nullity action with the Federal  Patent  Court in
Munich, Germany requesting that the  court  hold that  the patent was invalid  based on  prior art. On
October 1, 2015, the Federal Patent Court ruled  that the German portion of the  patent  was invalid.
Imra appealed this decision to the Federal  Court  of  Justice, the  highest civil jurisdiction court in
Germany. On March 27, 2018, the Federal Court of Justice dismissed Imra’s appeal effectively ending
the case in favor of Coherent.

Although we do not expect that such legal 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.

The United States and many foreign  governments  impose tariffs  and duties  on the import and
export of certain products we sell or  regulate the export of certain  products we sell.  From  time to time
our  customs compliance, product classifications, duty calculations and payments are reviewed or audited
by government agencies. For example,  one of the company’s  German  subsidiaries  is currently under
review by applicable German authorities regarding certain  historical exports of  products. Historically
these reviews, even where violations have been cited  and fines or other actions  have been taken, have
not resulted in materially negative consequences  to  the company.  In the  future any results  of  such
matters could, however, have materially negative effects on the company.

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 2015 and 2010, respectively, are
closed to examination. In our other major foreign jurisdictions and our  major state jurisdictions, the
years prior to fiscal 2012 and 2014, 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 the U.S., a legacy Rofin entity is under audit for fiscal 2016. In  Germany, various Coherent  and
legacy Rofin entities are under audit  for the years 2010 through 2016.  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.

The number of stockholders of record as  of November 23, 2018 was  526. While we paid  a cash
dividend in fiscal 2013 and may elect to pay  dividends in the future, we have no present intention to
declare cash dividends. Our line of credit agreement,  signed on November 7,  2016, includes certain
restrictions on our ability to pay cash  dividends.

There were no sales of unregistered  securities in fiscal 2018.

There were no stock repurchases during the fourth quarter of fiscal  2018.

Refer to Note 11 ‘‘Stock Repurchases’’  of  our  Notes to Consolidated Financial Statements under

Item 15 of this annual report for discussion  on repurchases during fiscal 2018 and 2016.

In November 2015, the FASB issued  amended guidance that clarifies  that  in a classified statement
of financial position, an entity shall classify deferred  tax  liabilities  and assets as noncurrent
amounts. The new guidance superseded  ASC 740-10-45-5  which required the valuation allowance
for a particular tax jurisdiction be allocated between current  and noncurrent deferred tax assets for
that tax jurisdiction on a pro rata basis. We  elected  to  early adopt the  standard retrospectively in
fiscal 2016, which resulted in the reclassification of  current deferred  income tax  assets to
non-current deferred income tax assets and non-current  deferred income tax liabilities on our
consolidated balance sheets for fiscal  2017, 2016 and 2015. The impact of the reclassifications  to
deferred tax assets and liabilities for  fiscal 2014  were immaterial.

(1) Includes $2.9 million of after-tax restructuring charges, $0.8 million impairment  and other  charges,

$0.7 million of after-tax acquisition costs, $0.6  million of  after-tax amortization of purchase
accounting step-up, $26.7 million of tax charges due to the U.S. Tax Cuts  and Jobs Act transition
tax and deferred tax remeasurement,  $3.3 million tax charge due to an increase in valuation
allowances against deferred tax assets  and $12.8 million of tax benefit from the adoption of new
rules for accounting for excess tax benefits and tax deficiencies for  employee stock-based
compensation.

(2) Includes $19.0 million of after-tax amortization of purchase accounting step-up,  $17.4 million of

after tax costs related to the acquisition of  Rofin, $8.4 million of after-tax restructuring charges, a
charge  of $1.9 million after-tax for the  impairment of net assets of several entities  held for  sale,
$1.8 million after-tax interest expense on the  commitment of our term loan to finance the
acquisition of Rofin, a $7.1 million after-tax gain on  our  hedge  of  our foreign exchange  risk related
to the commitment of our term loan  and  the issuance of debt to finance  the acquisition of Rofin,  a
$3.4 million after-tax gain on our sale of previously owned Rofin shares and a benefit of
$1.4 million from the closure of R&D tax audits.

(3) Includes $6.4 million of after tax  costs related  to  the acquisition of Rofin, a  $1.4 million after-tax
loss on our hedge of our foreign exchange risk related to the commitment  of our  term loan to
finance the acquisition of Rofin, $0.8 million after-tax interest expense on the commitment of our
term loan to finance the acquisition of Rofin and  a benefit of  $1.2 million from the renewal of the
R&D tax credit for fiscal 2015.

51

(4) Includes a charge of $1.3 million  after tax for  the impairment of  our investment  in SiOnyx, a
$1.3 million after-tax charge for an accrual related to an  ongoing  customs audit, a benefit  of
$1.1 million from the renewal of the R&D tax credit for  fiscal 2014 and $1.3  million gain  on our
purchase of Tinsley in the fourth quarter of fiscal  2015.

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 15 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.’’

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

Definitions and analysis of these performance indicators are as follows:

Net Sales

Net sales include sales of lasers, laser  tools, related  accessories and service. Net sales for fiscal
2018 increased 10.1% in our OLS segment  and  increased 10.9% in our ILS segment from fiscal 2017.
Net sales for  fiscal 2017 increased 58.3% in our  OLS  segment and increased  329.8% in our ILS
segment from fiscal 2016, with the majority of the  increase in the  ILS segment due to Rofin net sales

52

since the acquisition on November 7, 2016. For a description of additional  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  52.7% in
fiscal 2018 from 53.6% in fiscal 2017 and increased  from 48.3% in  fiscal 2016. Gross  profit percentage
for ILS increased to 26.7% in fiscal 2018  from 24.4% in fiscal 2017 and  from  26.0% in fiscal  2016. 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 increased slightly to 7.0% in  fiscal 2018 from
6.9% in fiscal 2017 and decreased from  9.5% in fiscal 2016. 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  shown 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. For  a
description of the reasons for changes in  Net  Cash Provided by  Operating Activities  refer to the
‘‘Liquidity and Capital Resources’’ section below.

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 360 days for years. 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 2018 increased to 67.2 days from  63.9 days  in fiscal 2017. The increase in  DSO  in receivables was
primarily due to a higher concentration of sales in the  last two months of  fiscal 2018 compared  to  fiscal
2017 in Asia and Japan including higher sales of ELA tools used in the flat panel  display market and
the timing of collection of those receivables, as well as slower collections  on  receivables in the  U.S.

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 2018 decreased  to 2.2 turns  from 2.6 turns in fiscal 2017  primarily as a result
of increased levels of inventory due to a  temporary decrease in demand  for sales of our large ELA

53

tools, slightly offset by increased service  inventory demand due to the increased installed  base  of  such
tools.

Capital Spending as a Percentage of Net  Sales

Capital spending as a percentage of net  sales  (‘‘capital  spending percentage’’)  is calculated as

capital expenditures for the period divided by net sales for the period. Capital  spending  percentage
indicates the extent to which we are  expanding or improving our operations, including  investments in
technology and equipment. Management  monitors  capital spending levels  as this assists us in  measuring
our  cash flows, net of capital expenditures.  Our capital  spending  percentage increased to 4.8%  in fiscal
2018 from 3.7% in fiscal 2017. Our capital  spending  percentage  decreased to 3.7%  in fiscal 2017 from
5.8% in fiscal 2016. The fiscal 2018 increase was primarily due to investments  made to expand our
manufacturing capacity in several manufacturing  sites in Germany  and South  Korea, higher purchases
of production-related assets and higher  spending on information technology infrastructure and office
consolidations to support our integration of Rofin. These increases  were partially offset by higher
revenues in fiscal 2018. The fiscal 2017 decrease  was  primarily  due to the impact of higher revenues in
fiscal 2017 partially offset by investments  to expand our manufacturing capacity in G¨ottingen,  Germany,
incremental capital spending due to our acquisition of Rofin in  the first  quarter of fiscal 2017, the
upgrade of certain of our production  facilities in  California and higher purchases of production-related
assets.

Adjusted EBITDA  as a Percentage of Net  Sales

We  define adjusted EBITDA as operating  income  adjusted for depreciation, amortization, stock

compensation expense, major restructuring costs and certain other non-operating  income  and expense
items, such as costs related to our acquisitions.  Key initiatives to reach our goals  for EBITDA
improvements include utilization of our  Asian manufacturing locations,  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  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  adjusted EBITDA in
order to enhance investors’ understanding of our ongoing operations. This  measure  is used by some
investors when assessing our performance.

SIGNIFICANT EVENTS

Acquisitions, divestitures and related  financing

On April 27, 2018, we completed the sale  of  several entities that we acquired in  the Rofin

acquisition. See Note 18, ‘‘Discontinued Operations and Sale of  Assets Held for  Sale’’  in the Notes to
Consolidated Financial Statements under Item  15 of this annual report for further discussion of the
divestiture.

On March 8, 2018, we acquired privately held O.R.  Lasertechnologie  GmbH and  certain assets of
its  U.S.-based affiliate (collectively ‘‘OR  Laser’’) for approximately $47.4 million, excluding transaction
costs. OR Laser produces laser-based material processing equipment for a variety of uses, including
additive manufacturing, welding, cladding, marking,  engraving  and drilling. See  Note 3,  ‘‘Business
Combinations’’ in our Notes to Consolidated Financial Statements under Item 15  of  this  annual report
for further discussion of the acquisition.

On November 7, 2016, we completed  our  acquisition of Rofin pursuant to the Merger Agreement

dated March  16, 2016. Rofin was one  of  the world’s leading developers and manufacturers of
high-performance industrial laser sources and laser-based solutions and components. The acquisition
was an all-cash transaction at a price of $32.50  per  share of Rofin common stock. The aggregate
consideration paid by us to the former  Rofin stockholders was approximately $904.5 million, excluding
related transaction fees and expenses.  We  also paid $15.3  million due  to  the  cancellation of  options
held by employees of Rofin. We funded  the payment of the aggregate consideration with  a combination
of our available cash on hand and the  proceeds  from the Euro Term Loan described below. As  a
condition of the acquisition, we were required to divest and hold separate  Rofin’s low power CO2 laser
business based in Hull, United Kingdom (the  ‘‘Hull Business’’),  and reported this business separately as
a discontinued operation until its divestiture. We  completed the divestiture of the Hull Business on
October 11, 2017, after receiving approval for the terms  of  the sale  from the European Commission.
See Note 3, ‘‘Business Combinations’’ and  Note 18, ‘‘Discontinued Operations and Sale of Assets Held
for Sale’’ in our Notes to Consolidated  Financial Statements under Item 15 of this annual  report for
further discussion of the acquisition and divestiture, respectively.

On November 7, 2016, we entered into a  Credit Agreement (the ‘‘Credit Agreement’’) with
Barclays  Bank PLC (‘‘Barclays’’), Bank of America,  N.A. (‘‘BAML’’) and MUFG Union Bank,  N.A.

55

(‘‘MUFG’’). The 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.  On November 7,
2016, the Euro Term Loan was drawn in  full and  its  proceeds were used to finance  our  acquisition  of
Rofin and pay related fees and expenses.  Also, on November 7,  2016, we used 10.0 million Euros of
the capacity under the revolving credit facility  for the  issuance  of  a letter  of credit.

On May 8, 2017, we entered into Amendment No.  1 and Waiver (the ‘‘Repricing Amendment’’)  to

the Credit Agreement. See Note 9, ‘‘Borrowings’’ in  the Notes to Consolidated  Financial Statements.

In relation to our acquisition of Rofin,  we paid  Barclays, our financial advisor,  a fee  of

approximately $9.5 million, $1.0 million of which  was  paid upon  delivery of the fairness  opinion in the
second  quarter of fiscal 2016, and the  remaining portion of which  was paid upon  consummation of the
acquisition in the first quarter of fiscal  2017; these  fees  were recorded  in selling, general and
administrative expense in our consolidated statements of operations.  We also paid Barclays,  BAML and
MUFG together approximately $17.0 million and $5.6 million for underwriting and upfront fees,
respectively, upon the close of the financing  on November 7, 2016; these  fees are recorded as debt
issuance costs on our consolidated balance sheets.

As a result of our acquisition of Rofin in  the first quarter of fiscal 2017,  we  reorganized into two
new reporting segments for the combined  company based upon our organizational structure and  how
our  Chief Operating Decision Maker receives  and utilizes  information  provided to allocate  resources
and make decisions: OLS and ILS. 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 medical applications,  as well as  in scientific research. Our ILS  business
segment delivers high performance laser  sources, sub-systems and tools primarily used for industrial
laser materials processing, serving important end markets like  automotive,  machine tool, consumer
goods and medical device manufacturing.

Stock Repurchases

On February 6, 2018, our board of directors authorized a stock repurchase  program authorizing

the Company to repurchase up to $100.0 million of  our common  stock  from time to time  through
January 31, 2019. During fiscal 2018,  we repurchased  and retired 574,946 shares of outstanding
common stock under this program at  an average price of  $173.91  per  share for a total of
$100.0 million.

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.

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 $759.9 million at September  29, 2018, including  a  significant  concentration in the  flat
panel  display market (32%) for customers which are  primarily  located  in Asia.  However, subsequent  to
year-end, one customer indicated its  intent to cancel  three purchase orders which  included orders
shippable within 12 months 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.

During  fiscal 2018, net sales increased by  $179.3 million, or 10%, compared to fiscal  2017, with a
significant increase in the microelectronics market and smaller increases in the OEM components and
instrumentation, scientific and government programs and materials processing  markets.  The increase  is
partially due to the inclusion of a full  year  of Rofin net  sales in fiscal 2018 compared  to  the inclusion
of Rofin’s net sales only after the November 7,  2016 acquisition  date in  fiscal 2017, or approximately
11 months. In addition, net sales in fiscal  2018 include $9.2 million of sales from the acquisition of  OR
Laser after the March 8, 2018 acquisition  date.  Given that we began to experience market softening in
the fourth quarter of fiscal 2018, particularly  in China, we expect  fiscal 2019 revenues to be 8%  to  12%
lower than fiscal 2018, with the second  half  of  fiscal 2019 expected to be stronger than the first half of
fiscal 2019.

During  fiscal 2018, Microelectronics sales increased $142.1  million, or 16%,  compared to fiscal
2017 primarily due to higher shipments related to ELA  tools used in  the flat panel display  market
including higher revenues from consumable parts as  well as  higher shipments related to semiconductor,
advanced packaging and solar applications. In microelectronics, we  expect that total  flat  panel  display
revenues, including both systems and  services, will decrease approximately 15% to 20%  in fiscal 2019
from fiscal 2018, although services revenue is expected  to  grow and  is expected to partially offset  the
expected decrease in systems revenue.  In  addition,  we have experienced and expect to experience some
customer push outs and order cancellations  over the next several quarters before the market begins to
recover in fiscal 2020. We expect the fiscal 2020  recovery to  be  driven by  additional  investment in
OLED capacity for consumer products. In semiconductor  applications within  the microelectronics
market, we expect semiconductor capital  equipment spending to decrease  in fiscal 2019 as a result  of
decreased memory prices and the impact  of  trade tariffs, partially offset by  strong service revenue. We
also expect fiscal 2019 demand in advanced packaging applications  to  be similar to fiscal 2018 levels.

Materials processing sales increased $9.0  million,  or 2%, during fiscal 2018 primarily due to the

inclusion of a full year of Rofin net sales  in  fiscal  2018, higher shipments for drilling  and marking
applications and the inclusion of seven months of OR Laser  net sales. Market conditions in  these
markets began to noticeably erode in  the fourth  quarter of fiscal  2018. This resulted in  some Chinese
customers pushing out or, to a lesser extent, cancelling  orders. In addition, the Chinese market was also
impacted by tariffs on U.S. goods and we experienced stronger price competition  for fiber laser
products in certain end markets. We  expect these impacts to continue into fiscal 2019.

58

The increase in the OEM components  and  instrumentation  market  of  $17.7 million, or 9%, during

fiscal 2018 was primarily due to higher  shipments for bio-instrumentation applications, which were
partially offset by lower shipments for military applications. Within  OEM components and
instrumentation applications, we are seeing strong demand  in the bio-instrumentation market,
particularly in flow cytometry and sequencing applications, higher demand for  consumables in  the
medical market, in dental applications and in  eye  disease management and strength in  defense
spending for directed-energy programs and in satellite optics.

The increase in scientific and government programs market sales of $10.4 million, or 9%,  during
fiscal 2018 was primarily due to higher  demand for  advanced  research  applications  used by university
and government research groups, particularly in  Asia and the US. We expect demand in  the scientific
and government programs market to  continue  to  fluctuate from quarter to  quarter.

During  the fourth quarter of fiscal 2018,  one of our German manufacturing sites, which we
acquired as part of the Rofin acquisition, had  a manufacturing parts shortage due to difficulties by
operations/manufacturing personnel in  using newly implemented Enterprise Management Systems.
Unfortunately this shortage caused the  site’s inability to convert $6 million of inventory into shippable
products. As a result not only were we  unable to convert certain orders into revenue,  we were required
to use new rather than refurbished materials for service. We have taken various remedial actions to
correct the situation, including changes  in processes, responsibilities  and  personnel. We  anticipate
having these remedies completed by the  end of the first  quarter of fiscal 2019.

During  fiscal 2017, net sales increased by $865.9 million, or 101%, compared to fiscal 2016, with

significant increases in the microelectronics and materials processing  markets,  a smaller  increase in the
OEM components and instrumentation  market and a decrease  in the scientific and  government
programs market. Net sales in fiscal 2017 included $434.9  million  of Rofin  net sales since the
acquisition on November 7, 2016, primarily in the materials processing market. Microelectronics  sales
increased $439.3 million, or 97%, primarily due to higher  shipments related to ELA tools used  in the
flat panel display market including higher  revenues from consumable parts as well as  higher shipments
related to advanced packaging and semiconductor applications. Materials processing sales  increased
$387.9 million, or 313%, during fiscal 2017 primarily due to the addition of Rofin net  sales and higher
shipments for machine tools, automotive  and other  materials  processing applications.  The  increase in
the OEM components and instrumentation  market  of  $41.5 million, or 26%,  during  fiscal 2017 was
primarily due to higher shipments for military,  medical and bio-instrumentation applications,  with much
of the increase in military applications  due to our acquisition of Rofin.  The  decrease in scientific and
government programs market sales of  $2.8 million, or  2%, during fiscal  2017 was primarily due to lower
demand for advanced research applications used by university and government  research  groups in
the U.S.

The timing for shipments of our higher average selling price  excimer  products in the flat panel
display  market has historically fluctuated and is in the  future expected 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 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%-12% below the fourth
quarter of the prior fiscal years.

In fiscal  2018, 2017 and 2016, one customer accounted  for 26%, 23% and 13% of  net sales,

respectively. In fiscal 2016, another customer accounted for 16% 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 medical applications, as well as  in scientific research. ILS delivers high
performance laser sources, sub-systems and tools primarily used for industrial  laser materials
processing, serving important end markets  like automotive, machine tool, consumer goods and  medical
device manufacturing.

The following table sets forth, for the periods indicated,  the amount of net sales  and their relative

percentages of total net sales by segment  (dollars in thousands):

Net sales for fiscal 2018 increased $179.3 million, or 10%, compared  to  fiscal  2017, with increases

of $115.9 million, or 10%, in our OLS segment  and  increases  of $63.4 million, or 11%,  in our ILS
segment. The fiscal 2018 increases in  both OLS and  ILS segment sales included increases due to the
favorable impact of foreign exchange  rates. Net  sales for fiscal  2017 increased $865.9  million, or  101%,
compared to fiscal 2016, with increases  of $421.1 million,  or 58%, in our  OLS segment and increases of
$444.8 million, or 330%, in our ILS segment. The impact of  foreign exchange rates  was not significant
to fiscal 2017 sales in either segment.

The increase in our OLS segment sales in  fiscal  2018 was primarily  due to  higher shipments  of
ELA tools used in the flat panel display market and higher revenues from consumable parts as well  as
higher  shipments for scientific and government programs, bio-instrumentation, semiconductor,  solar and
advanced packaging applications. These  increases  were  partially offset  by  lower shipments for materials
processing applications. The increase  in  our OLS segment sales  in fiscal 2017 was primarily due to
higher  shipments of ELA tools used  in the  flat panel display market and higher revenues from
consumable parts as well as higher shipments for  semiconductor and advanced packaging applications.

The increase in our ILS segment sales  from fiscal 2017 to  fiscal 2018 was  primarily  due  to  higher
shipments for microelectronics applications and materials  processing applications including  a full year
of Rofin net sales and seven months of OR Laser net  sales in fiscal 2018. The increase  in our ILS
segment sales from fiscal 2016 to fiscal 2017 was primarily due to higher shipments for materials
processing, microelectronics and OEM components  and instrumentation applications due to our
acquisition of Rofin ($429.2 million)  as well as  higher shipments to the medical, flat panel  display and
advanced  packaging  markets.

Gross Profit

Consolidated

Our gross profit percentage increased  by  0.2% to 43.7% in fiscal 2018 from 43.5% in fiscal 2017
primarily due to the 1.5% favorable net  impact  of  lower purchase  accounting adjustments and lower
restructuring costs  (0.2%) compared to fiscal 2017  partially offset by the 1.5% unfavorable  impact  of
higher  product costs including higher  warranty  and installation costs and higher other costs.  In fiscal

60

2017, we took a larger charge (1.5%) for amortization  of  inventory step-up  related to our acquisition of
Rofin compared to the charge in fiscal 2018 related to our acquisition of  OR  Laser. Also contributing
to the increase in gross profit percentage  were lower restructuring  charges  (0.2%) for inventory
write-offs, primarily in our ILS segment. This favorable net impact was partially offset  by  the impact
from higher warranty events in both segments, with  the largest impact  from high power fiber  lasers,
unfavorable mix in the microelectronics market and unfavorable costs in certain materials processing
markets partially offset by better leverage  of manufacturing costs  on higher volumes  and favorable mix
in certain materials processing markets.

Our gross profit percentage decreased by 1.0% to 43.5%  in fiscal 2017 from 44.5% in  fiscal 2016
primarily due to the impact of purchase accounting adjustments (4.0%) for amortization of inventory
step-up and amortization of intangibles  related to our acquisition of Rofin in the first quarter of fiscal
2017. Also contributing to the decrease was the impact of our acquisition of Rofin due to Rofin’s
margins that are lower than Coherent’s historical margins (3.6% before considering purchase
accounting adjustments). The decreases were partially offset by  improvements  in margins of  Coherent
historical products (6.6%) primarily due  to  the favorable leverage of manufacturing costs on higher
volumes and favorable mix in flat panel display applications for both system sales and service, as well as
the favorable impact of foreign exchange  rates, lower  inventory provisions  for excess and obsolete
inventory, reduced freight costs and lower warranty costs as a  percentage of sales due to the  impact  of
significantly higher net sales.

Our gross profit percentage has been  and will continue to be affected by  a variety of factors

including market and product mix, pricing  on volume orders, shipment volumes, 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,
new product introductions, production  volume, customization and  reconfiguration of  systems,
commodity prices and foreign currency fluctuations, particularly the recent volatility of the  Euro and a
lesser extent, the Japanese Yen and South Korean Won.

OEM Laser Sources

Our OLS gross profit percentage decreased by  0.9% to 52.7%  in fiscal 2018 from  53.6% in fiscal
2017 primarily due to unfavorable product  margins (0.9%) and increased  warranty  and installation costs
as a percentage of  sales (0.3%) due to higher warranty  events  in the  microelectronics  and scientific and
government programs markets, primarily  in  China, and higher installation costs  for flat panel display
applications. The unfavorable product margins were due to unfavorable mix  within flat panel display
applications for both systems and service  as well as other  microelectronics  applications and  the
unfavorable impact of the stronger Euro and Won, all  of  which were partially offset by better  leverage
of manufacturing costs on higher volumes. These unfavorable impacts were partially offset by lower
intangibles amortization (0.2%) as a percentage of sales and lower other costs (0.1%) due to lower
inventory provisions for excess and obsolete inventory as a percentage of  sales  in certain business units
and the impact of significantly higher  sales.

Our OLS gross profit percentage increased by 5.3% to 53.6% in fiscal 2017  from 48.3% in  fiscal
2016 primarily due to favorable product margins (4.1%) as  a result of  favorable mix within flat panel
display  applications for both systems and service,  favorable mix in other microelectronics and materials
processing applications and higher leverage of manufacturing costs  on higher  volumes, as well as  the
favorable impact of the weaker Euro  and  stronger Yen and Won compared to fiscal  2016. Also
contributing to the increase in gross profit percentage as  a percentage of  sales  due  to  the impact of
significantly higher sales volumes were  lower other costs (0.7%)  due to lower inventory provisions for
excess and obsolete inventory and reduced  freight and duty  costs  in certain  business  units, lower
intangibles amortization (0.3%) and lower installation and warranty  costs  (0.2%).

61

Industrial Lasers & Systems

Our ILS gross profit percentage increased by  2.3% to 26.7%  in fiscal 2018 from 24.4% in fiscal
2017 primarily due to 4.4% lower amortization of inventory step-up (4.5% in fiscal  2017 related  to  our
acquisition of Rofin compared to 0.1%  in  fiscal 2018  related to our  acquisition of OR  Laser) as  well as
lower restructuring charges (0.7%) related to the implementation  of planned restructuring  activities in
connection with the acquisition of Rofin, which were primarily related  to  the exit from  our  preexisting
high power fiber laser product line net of  higher service  inventory write-offs. Partially offsetting the
improvement, intangibles amortization increased as  a percentage of sales  (0.5%)  due  to  the inclusion  in
fiscal 2018 of a full year of amortization for  the Rofin acquisition  and  seven months of amortization
related to the OR Laser acquisition.  Excluding the 4.6%  favorable net impact of lower  purchase
accounting adjustments and lower restructuring costs, gross profit percentage decreased 2.6% compared
to fiscal 2017 primarily due to unfavorable product  margins including warranty costs (2.6%)  as a
percentage of sales. The unfavorable  product margins were due  to  higher warranty events  in materials
processing applications, primarily high power fiber lasers, and  the  impact  from unfavorable product
costs in certain materials processing applications  partially offset by  the better  leverage of  manufacturing
costs on higher volumes and favorable  mix.

Our ILS gross profit percentage decreased  by 1.6% to 24.4% in fiscal  2017 from 26.0% in fiscal

2016 primarily due to the impact of purchase accounting adjustments (11.1%)  for amortization  of
intangibles and inventory step-up related  to  our  acquisition of Rofin in the first quarter of fiscal 2017
and restructuring costs (1.1%) related  to  the implementation of planned restructuring  activities in
connection with our acquisition of Rofin, which  were primarily related to  the exit from our preexisting
high power fiber laser product line and other Rofin product  lines. The decreases in  gross profit
percentage were partially offset by the favorable impact of  Rofin’s margins before considering purchase
accounting adjustments. Rofin’s high-power fiber laser and  global tools businesses have higher margins
than Coherent’s legacy ILS businesses.

Research and development

Fiscal 2018 research and development (‘‘R&D’’) expenses increased $13.4  million,  or 11%, from
fiscal 2017, and increased slightly to 7.0%  of sales,  compared  to  6.9% in fiscal  2017. The increase was
primarily due to $8.3 million higher spending  on R&D activities, the inclusion of a full  year of  Rofin
R&D expenses ($3.2 million) in fiscal 2018 and  $1.4 million in incremental spending due to the

62

acquisition of OR Laser in the second quarter  of fiscal 2018. The  higher spending on R&D  activities
includes higher spending on headcount  and materials as well  as the  unfavorable impact of foreign
exchange rates (primarily the stronger  Euro), which was partially  offset by lower  restructuring charges
for our  exit from our preexisting Coherent  high power fiber laser  product line in the  first  quarter  of
fiscal 2017. On a segment basis, as compared  to  the prior year, OLS R&D spending increased
$6.5 million primarily due to higher net spending  on R&D  activities including the unfavorable  impact
of foreign exchange rates. ILS R&D spending increased  $6.4 million primarily due to the inclusion  of a
full year of Rofin R&D expenses, higher  spending on R&D activities including the unfavorable impact
of foreign exchange rates and the acquisition of OR Laser,  which was partially offset by lower
restructuring costs. Corporate and other  R&D spending increased $0.5 million primarily due to higher
headcount spending in our Advanced  Research  Business unit.

Fiscal 2017 R&D expenses increased $37.4 million, or 46%,  from fiscal 2016,  but decreased to

6.9% of sales, compared to 9.5% in fiscal 2016. The increase  in R&D expenses was primarily due to
the addition of Rofin R&D expenses  ($32.0  million, excluding $0.7 million of restructuring costs for
severance) since the acquisition on November  7, 2016,  $2.2  million  higher project spending, including
higher  variable compensation and lower reimbursements from customers, and  $2.1 million of
restructuring costs  related to the exit from our preexisting Coherent high power fiber laser product line
in the first quarter of fiscal 2017. There were  also increases  of $0.8 million for  higher stock-based
compensation expense including $0.4 million related to a charge recorded in  the first quarter of fiscal
2017 due to the acceleration of Rofin  options and $0.3  million higher  charges for  increases in deferred
compensation plan liabilities. On a segment basis, as compared to the prior year period, OLS R&D
spending increased $7.4 million primarily  due to higher net spending on projects. ILS R&D  spending
increased $27.7 million primarily due  to  our acquisition of Rofin and restructuring  costs, partially offset
by lower project spending. Corporate and other R&D  spending increased $2.3  million  due  to  higher
project spending in our advanced research  business unit, higher  stock-based compensation  expense and
higher  charges for increases in deferred compensation  plan liabilities.

Selling, general and administrative

Fiscal 2018 selling, general and administrative  (‘‘SG&A’’)  expenses increased $1.5 million, or  1%,

from fiscal 2017. The increase was primarily due to the inclusion of a full  year  of  Rofin  SG&A
expenses ($8.0 million) in fiscal 2018 and $5.1 million higher  other variable  spending  (including the
unfavorable impact of foreign exchange rates) on  consulting  and infrastructure related to integration
activities and in support of higher sales, which was partially offset by  lower restructuring costs due to
lower severance costs and a gain on  the sale of a  building in  the third  quarter  of  fiscal 2018. In
addition, SG&A expenses increased due to $2.4 million higher incremental  spending  from the
acquisition of OR Laser in the second quarter  of fiscal 2018, $1.2  million  higher stock-based
compensation expense, $1.1 million higher charges for increases  in deferred  compensation plan
liabilities and $0.6 million higher payroll spending primarily due  to  the unfavorable impact of foreign
exchange rates and higher spending on salaries,  benefits and commissions  net of lower variable
compensation. The increase in stock-based compensation expense  was  due to higher expense  for new
grants offset by the $3.4 million charge recorded in the first quarter of fiscal  2017 due to the
acceleration of Rofin options. The increases were  offset by $16.9  million  lower financial advisory,
consulting and legal costs related to  acquisitions. On  a segment basis, as compared  to  the prior year,
OLS SG&A expenses increased $7.1  million primarily due  to higher  payroll and other variable spending
(including the unfavorable impact of  foreign exchange rates)  as well as  spending relating to a  historical
Rofin business unit that is included in  our  OLS segment.  ILS SG&A  spending  increased $8.6 million
primarily due to the inclusion of a full year of Rofin expenses,  the unfavorable impact of foreign
exchange rates, the acquisition of OR Laser and higher other variable spending partially offset  by  lower
payroll  spending including lower severance restructuring and variable compensation costs. Corporate
and other SG&A spending decreased $14.1  million primarily due to lower  financial advisory, consulting

63

and legal costs related to our acquisition  of Rofin partially offset by  higher stock-based compensation
expense, higher charges for increases  in deferred compensation plan liabilities and higher payroll
spending including higher spending on benefits net of lower  variable  compensation.

Fiscal 2017 SG&A expenses increased $122.9 million, or  73%, from fiscal 2016.  The increase was

primarily due to the addition of Rofin SG&A  expenses ($75.2  million excluding  $2.6 million
restructuring costs  for severance) following  the acquisition in the  first quarter  of  fiscal 2017,
$15.5 million higher other spending on legal, consulting and infrastructure  related to integration
activities and the debt repricing as well as other  variable  spending in support of higher  sales,
$11.1 million higher payroll spending for  variable compensation, commissions and salaries  and benefits
and $7.7 million higher financial advisory,  consulting and legal costs related  to  our  acquisition  of  Rofin.
SG&A expense also increased due to $8.6  million  higher stock-based compensation expense, including
$3.4 million related to a charge recorded in the  first quarter of fiscal 2017  due  to  the acceleration of
Rofin options, as well as higher expense  for new grants, $3.4 million of restructuring  costs (primarily
severance) and $1.4 million higher charges for increases  in deferred compensation plan liabilities.  On a
segment basis, as compared to the prior  year period,  OLS SG&A  segment  expenses increased
$22.4 million primarily due to higher payroll and other variable spending as  well as spending relating to
a historical Rofin business unit which  is  included  in our OLS segment. ILS SG&A spending increased
$74.3 million primarily due to our acquisition  of  Rofin ($78.7 million) and higher payroll  and other
variable spending. Corporate and other SG&A spending increased $26.2 million primarily due to higher
financial advisory, consulting and legal  costs related to our  acquisition of Rofin, higher stock-based
compensation expense, higher charges for  increases in  deferred compensation plan liabilities and higher
payroll  spending.

Gain on business combination

On November 7, 2016, we acquired Rofin at a price  of $32.50 per share of Rofin common  stock

(See Note 3, ‘‘Business Combinations’’ in  the Notes  to  Consolidated  Financial Statements). We
recognized a gain of $5.4 million in our consolidated statements  of operations in the  first  quarter  of
fiscal 2017 on the increase in fair value from  the date  of purchase for the shares  of Rofin we owned
prior to the acquisition.

Impairment and other charges

In the fourth quarter of fiscal 2017, management decided to sell several entities  that  we acquired

in the Rofin acquisition. Although the  sale  was  not  completed as of the end of  fiscal  2017, we  recorded
a non-cash impairment charge of $2.9 million to operating expense in our results of  operations in the
fourth quarter of fiscal 2017 to reduce our  carrying value in  these  entities  to  fair value. We completed
the sale of these entities on April 27,  2018. In fiscal 2018,  we recorded additional charges of
$0.3 million related to the impairment  and sale of these entities.  See  Note 18,  ‘‘Discontinued
Operations and Sale of Assets Held for Sale’’  in the Notes  to  Consolidated Financial Statements. In
addition, in fiscal 2018, we recorded impairment  charges  of  $0.5 million to reduce the  carrying value of
a building to its fair value.

Amortization of intangible assets

Amortization of intangible assets decreased  $5.3 million, or 33%,  from  fiscal 2017 to fiscal  2018

primarily due to the completion of the  amortization  of  backlog  intangibles from our acquisition of
Rofin in fiscal 2017 ($5.5 million lower),  which was partially offset by the inclusion of a full year of
Rofin amortization expenses in fiscal  2018,  the unfavorable impact of  foreign  exchange rates and
amortization of intangibles related to  our  acquisition of OR  Laser  in the second quarter of  fiscal  2018.

64

Amortization of intangible assets increased $13.2 million, or  464%,  from fiscal 2016  to  fiscal  2017

primarily due to our acquisition of Rofin  in the  first  quarter  of fiscal 2017.

Other income (expense), net

Other income (expense), net, changed by $8.0  million  to  other expense of $31.5 million  in fiscal

2018 from other expense of $23.4 million  in fiscal 2017. The higher  expenses were primarily  due  to
$15.9 million lower foreign exchange  net gains (higher  net losses)  resulting primarily from a  gain in the
first quarter of fiscal 2017 of $11.3 million on  forward contracts associated  with our foreign exchange
risk related to the commitment and issuance of our Euro Term  Loan  to  finance the  acquisition  of
Rofin, the impact of changing rates on cash conversions and higher points on forward contracts due to
higher  hedge volumes. The lower foreign exchange  gains were offset  by $8.5 million lower interest
expense due to lower interest on the  Euro  Term  Loan  resulting from  our paydown of principal and an
interest rate reduction, which were partially  offset by higher amortization of debt issuance costs  related
to the Euro Term loan.

Other income (expense), net, changed by $18.7  million  to  other expense of $23.4 million  in fiscal

2017 from other expense of $4.7 million  in fiscal 2016.  The  higher expenses were  primarily  due  to
higher  interest expense of $33.0 million  partially offset by  $11.0 million higher foreign  exchange gains
and $3.2 million higher gains, net of expenses,  on our deferred compensation plan  assets, including a
death benefit of $1.3 million. Interest  expense increased due  to  interest on the  Euro  Term Loan and
interest on the commitment of the Euro  Term Loan to fund our acquisition of Rofin as well as
amortization of debt issuance costs related to the Euro Term  Loan. The higher foreign exchange gains
were primarily due to a gain of $11.3  million on forward  contracts associated with our foreign exchange
risk related to the commitment of our Euro Term  Loan and the issuance of  the Euro  Term Loan to
finance our acquisition of Rofin partially offset  by the  impact of changing  rates on cash conversions.

Income taxes

On December 22, 2017, the Tax Cuts and Jobs Act (the  ‘‘Tax Act’’)  was enacted. The Tax Act

changes are broad and complex. The  final  impact of the  Tax Act may  materially differ from the
provisional estimates provided. Among other things, this  may be due  to  changes in  interpretations of
the Tax Act, any legislative action to address questions that arise because of the Tax Act and any
changes in accounting standards for income taxes or  related interpretations in response to the  Tax Act.
Additionally, long-standing international  tax policies that determine each country’s  jurisdiction  to  tax
cross-border international trade are evolving as a  result of the  Base Erosion and Profit  Shifting
reporting requirements (‘‘BEPS’’) recommended by the  G8, G20  and  Organization for Economic
Cooperation and Development (‘‘OECD’’).  As these and other tax laws and related regulations change,
our  financial results could prospectively  be materially impacted. Given the unpredictability  of these
possible changes and their potential  interdependency, it is very difficult to assess whether  the overall
effect of such potential tax changes would be cumulatively positive or negative for our earnings and
cash flow. Such changes could, however,  adversely impact our financial  results.

As discussed in Note 15, ‘‘Income Taxes’’ in  the Notes to Consolidated  Financial Statements,  the
Tax  Act resulted in a provisional charge of  $26.7 million for  the year  ended September  29, 2018. This is
comprised of an estimated deemed repatriation  tax charge of $17.8  million  less  a previously recorded
deferred tax liability of $20.3 million for anticipated repatriation  of  our investment in a  foreign
subsidiary, plus an estimated deferred  tax  remeasurement charge of $15.5  million and an accrual for
foreign withholding taxes and state income taxes of  $13.7 million on certain  foreign earnings not
considered  permanently  reinvested.

The effective tax rate on income from continuing operations  before  income taxes for fiscal 2018 of

31.6% was higher than the effective U.S.  federal blended tax rate of 24.5% primarily due to the Tax

65

Act’s one-time mandatory deemed repatriation transition tax, the impact of  income  subject to foreign
tax rates that are higher than the U.S.  tax  rates, the remeasurement of deferred  tax assets and  liabilities
based on the newly enacted U.S. federal  tax rate  of 21.0%, an  accrual for  foreign withholding taxes and
state income taxes on certain 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 (‘‘IRC’’) Section 162(m).  These amounts  are partially  offset by the  excess
tax benefits from stock award exercises  and  restricted stock unit vesting, the  benefit of foreign tax
credits, the benefit of federal research and development tax credits, the benefit  of a domestic
manufacturing deduction under IRC  Section 199 and the Singapore tax exemption.

As a result of the adoption of the new accounting standard on share-based  compensation  in fiscal

2018, our effective tax rate will increase  or  decrease based upon the tax effect of the  difference
between the share-based compensation expenses and the benefits  taken  on the Company’s tax returns.
We  recognize excess tax benefits on a  discrete basis  and therefore  anticipate the effective  tax rate to
vary from quarter to quarter depending on our share price in  each period.

The effective tax rate on income from continuing operations  before  income taxes for fiscal 2017 of
30.9% was lower than the statutory rate  of 35.0%.  This was primarily due to differences  related to the
benefit of income subject to foreign tax rates that are  lower than U.S. tax rates including the Singapore
tax exemption, the benefit of foreign tax  credits  and federal research and development  tax credits, the
benefit of a domestic manufacturing  deduction  under IRC Section 199 and  the release of certain  tax
reserves due to audit settlement. These amounts  are partially offset by  Rofin transaction costs not
deductible for tax purposes, tax costs  of Rofin restructuring, ASC  740-10 (formerly FIN48) tax liabilities
for transfer pricing, stock-based compensation  not  deductible for tax  purposes and limitations on  the
deductibility of compensation under  IRC  Section 162(m).

The effective tax rate on income from continuing operations  before  income taxes for fiscal 2016 of
28.8% was lower than the statutory rate  of 35.0%.  This was primarily due to differences  related to the
benefit of income subject to foreign tax rates that are  lower than U.S. tax rates including the Singapore
tax exemption, the benefit of foreign tax  credits  and the  benefit of federal research and development
tax credits including renewal of the federal research and development tax credits for fiscal 2015. These
amounts are partially offset by deemed dividend  inclusions under the Subpart F tax  rules,  stock-based
compensation not deductible for tax  purposes  and limitations on  the deductibility of compensation
under IRC Section 162(m).

In October 2016, Coherent Singapore received an  amended Pioneer Status  tax exemption  from the

Singapore authorities effective from fiscal 2012  through fiscal 2021. The tax  holiday continues  to  be
conditional upon our meeting certain revenue,  business spending and employment thresholds.  The
impact of this tax exemption decreased Singapore income taxes  by approximately $2.5  million,
$1.1 million and $0.7 million in fiscal  2018, 2017 and 2016,  respectively.

FINANCIAL  CONDITION

Liquidity and capital resources

At September 29, 2018, we had assets  classified as cash and  cash  equivalents and short-term
investments, in an aggregate amount  of  $310.6  million, compared  to  $475.6 million at September 30,
2017. This decrease was primarily due  to  the paydown of debt of $173.3 million and the repurchase  of
$100.0 million of our common stock  in fiscal 2018. In addition, at  September 29,  2018, we  had
$13.6 million of restricted cash. At September 29, 2018, approximately $215.7  million of  our cash and
securities was held in certain of our foreign subsidiaries  and branches, $191.2 million of which  was
denominated in currencies other than the U.S. dollar. At  September  29, 2018,  we had approximately
$214.9 million of cash held by foreign subsidiaries including certain entities  where we intend  to
permanently reinvest our accumulated  earnings and our current plans do  not  demonstrate  a need for

66

these funds to support our domestic operations. If,  however,  a portion  of  these  funds  are needed for
and distributed to our operations in the  United States, 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. However,  we
have reevaluated our historic assertion  as a  result of the  enactment of the  Tax Act and no  longer
consider certain historic 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.

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 three 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 domestic line of credit. Our historical uses of cash have primarily been
for acquisitions of businesses and technologies, the  repurchase of our common  stock, capital
expenditures 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 $148.0  million  in fiscal 2018 compared to
fiscal 2017 and increased by $278.8 million  in fiscal 2017  compared to fiscal  2016. The decrease in cash
provided by operating activities in fiscal  2018 was primarily due to lower cash  flows  from deferred
revenue, income taxes payable and payroll accruals  as well as  the  timing of shipments  of  large systems,
which  were partially offset by higher  net income and higher cash  flows due to non-cash expenses for
amortization, stock-based compensation and depreciation.  The increase in  cash provided by operating
activities in fiscal 2017 was primarily due  to  higher net income,  higher cash flows due to higher
non-cash expenses for amortization, stock-based compensation and depreciation, higher income taxes

67

payable, higher deferred revenue and higher  cash flows from  the timing of shipments  of large systems
from inventory partially offset by lower  cash flows from accounts receivable. We  believe that our
existing cash, cash  equivalents and short  term investments  combined with cash  to  be  provided by
operating activities and amounts available  under our revolving credit facility 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. 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 additional borrowings  (as in our acquisition of Rofin), existing cash
balances and cash flows from operations  (as  in our acquisition of OR  Laser). 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 November 7, 2016, we entered into a  Credit Agreement with Barclays, as administrative agent

and an L/C Issuer, BAML as an L/C Issuer,  and  MUFG as an  L/C  Issuer (the ‘‘Credit Agreement’’)
that 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 (‘‘Revolving  Credit  Facility’’) with  a $30.0 million
letter of credit sublimit and a $10.0 million swing  line sublimit. We borrowed the full  670.0 million
Euros under the Euro Term Loan and its proceeds were used to finance our  acquisition  of Rofin  and
pay related fees and expenses. On November 7, 2016, we also used 10.0 million Euros of the capacity
under the Revolving Credit Facility for  the issuance of  a letter of  credit. We were in  compliance with
all covenants at September 29, 2018. See  Note 9,  ‘‘Borrowings’’ in the Notes to Consolidated Financial
Statements.

The aggregate consideration paid by  us  to  the former Rofin  stockholders in the first quarter of
fiscal 2017 was approximately $904.5  million, excluding  related  transaction fees and  expenses. We  also
paid $15.3 million due to the cancellation  of options held by employees  of Rofin. We incurred
approximately $26.4 million of debt issuance  costs in  fiscal  2017. In fiscal 2017,  we made debt principal
payments $178.1 million, including voluntary prepayments of $170.7 million, recorded interest expense
on the Euro Term Loan of $23.5 million,  recorded $7.2 million  amortization of debt issuance costs  and
recorded  interest expense of $2.7 million for  the commitment  of the Euro Term Loan. In  fiscal 2018,
we made debt principal payments $170.1 million, including  voluntary prepayments of $162.1  million,
recorded  interest expense on the Euro Term Loan of $14.9  million and recorded $9.6  million
amortization of debt issuance costs.

In relation to our acquisition of Rofin,  we paid  Barclays, our financial advisor,  a fee  of

approximately $9.5 million, $1.0 million of which  was  paid upon  delivery of the fairness  opinion in the
second  quarter of fiscal 2016, and the  remaining portion of which  was paid upon  consummation of the
acquisition in the first quarter of fiscal  2017; these  fees  were recorded  as SG&A expense.

On March 8, 2018, we acquired privately held OR  Laser  for approximately $47.4  million,  excluding

transaction  costs.

On April 27, 2018, we completed the sale  of  several entities that we acquired in  the Rofin

acquisition for approximately $6.3 million.

68

On February 6, 2018, our board of directors authorized a stock repurchase  program authorizing

the Company to repurchase up to $100.0 million of  our common  stock  from time to time  through
January 31, 2019. During fiscal 2018,  we repurchased  and retired 574,946 shares of outstanding
common stock under this program at  an average price of  $173.91  per  share for a total of
$100.0 million. See Note 12, ‘‘Stock Repurchases’’ in the  Notes  to  Consolidated Financial Statements.

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. See Note  11, ‘‘Stock Repurchases’’ in the  Notes
to Consolidated Financial Statements.

On October 5, 2018, we completed two  small acquisitions totaling approximately $19.0  million. See

Note 19, ‘‘Subsequent Events’’ in the Notes  to  Consolidated  Financial Statements.

Additional sources of cash available  to  us  were international currency lines of credit and bank
credit facilities totaling $26.5 million as  of September 29, 2018,  of which $18.5  million  was  unused and
available. These unsecured international credit facilities  were  used  in Europe and  Japan  during fiscal
2018. As of September 29, 2018, we  had utilized $8.0  million of the international credit facilities as
guarantees in Europe.

Our ratio of current assets to current liabilities increased to 3.3:1 at September 29, 2018  compared

to 3.1:1 at September 30, 2017. The increase in our ratio was primarily due to lower deferred income
and higher inventories, which were partially  offset by lower  cash  and cash equivalents. Our  cash and
cash equivalents, short-term investments  and  working  capital  are  as follows (in thousands):

Because of the uncertainty as to the timing of such  payments, we have excluded  cash payments
related to our contractual obligations for  our deferred compensation plans aggregating  $41.7 million at
September 29, 2018. As of September 29,  2018, we had gross unrecognized tax benefits of $70.3 million
which  includes penalties and interest  of $4.4 million.  Approximately  $36.3 million has been recorded as
a noncurrent  liability. At this time, we are unable to make a  reasonably  reliable estimate of the timing

69

of payments in individual years in connection with  these  tax liabilities;  therefore, such  amounts are not
included in the above contractual obligation table.

Changes  in financial condition

Cash provided by operating activities in  fiscal 2018 was $236.1 million,  which included net income

of $247.4 million, depreciation and amortization of $122.9 million, stock-based compensation  expense of
$32.7 million and net decreases in deferred tax assets of $16.6 million, partially offset  by  cash used by
operating assets and liabilities of $187.1  million (primarily increases in inventories,  increases in  accounts
receivable, decreases in deferred income  and decreases  in accrued  payroll). Cash  provided by operating
activities in fiscal 2017 was $384.1 million,  which included net income of $207.1  million, depreciation
and amortization of $111.4 million, cash provided by  operating assets  and liabilities  of  $54.8 million
(primarily increases in taxes payable,  deferred  income and  accounts payable net  of  increases in  accounts
receivable and inventories) and stock-based  compensation  expense of $26.3  million,  partially offset by
increases in net deferred tax assets of  $19.8 million.

Cash used in investing activities in fiscal 2018  was  $67.7 million, which  included $86.4  million,  net

of proceeds from dispositions, used to acquire property and  equipment and to purchase and  upgrade
buildings and $45.4 million net of cash acquired to purchase OR  Laser partially offset by $32.3 million
net sales of available-for-sale securities,  $25.0 million proceeds  from  the sale of discontinued  operations
and $6.3 million proceeds from the sale  of other entities. Cash used in  investing  activities in fiscal  2017
of $810.3 million included $740.5 million net of cash acquired to purchase Rofin, $61.8 million,  net of
proceeds from dispositions, used to acquire  property and equipment and  to  purchase  and upgrade
buildings and $7.2 million net purchases of available-for-sale securities.

Cash used in financing activities in fiscal 2018 was $299.0 million, which included  $173.3 million

net debt payments, $100.0 million repurchases of our common stock and  $36.3 million outflows due to
net settlement of restricted stock units  partially  offset by $10.6 million generated  from our  employee
purchase plans. Cash provided by financing activities  in fiscal  2017 was $506.0 million, which  included
$539.1 million net borrowings and $8.1  million generated  from our employee purchase plans partially
offset by $26.4 million of debt issuance  costs and $15.7 million outflows due to net settlement of
restricted stock units.

Changes in exchange rates in fiscal 2018 resulted in a decrease in cash balances of $2.4  million.

Changes in exchange rates in fiscal 2017  resulted in an increase  in cash balances of $22.9  million.

RECENT  ACCOUNTING  PRONOUNCEMENTS

See Note 2, ‘‘Significant Accounting Policies’’ in  the Notes to Consolidated  Financial Statements
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

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 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 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

70

combinations, accounting for long-lived  assets (including  goodwill and intangible assets),  inventory
valuation, warranty reserves and accounting  for  income  taxes.

Revenue Recognition

We  recognize revenue when all four  revenue recognition criteria  have been met: persuasive
evidence of an arrangement exists, the  product has  been delivered or  the  service  has been  rendered,
the price is fixed or determinable and collection is probable.  Revenue from  product sales is  recorded
when all of the foregoing conditions are met and  risk  of  loss  and title passes to the customer. Our
products typically include a warranty and the estimated cost of product  warranty claims  (based  on
historical experience) is recorded at the  time  the sale is recognized. Sales to customers are generally
not subject to any price protection or return  rights.

The majority of our sales are made to original equipment manufacturers (‘‘OEMs’’), distributors,

representatives and end-users in the non-scientific market.  Sales  made to these customers do not
require installation of the products by  us and are not subject to other post-delivery obligations,  except
in occasional instances where we have  agreed to perform  installation  or provide training. In those
instances, we defer revenue related to  installation  services or training  until these  services have been
rendered. We allocate revenue from multiple element arrangements to the various  elements based upon
fair values or a selling price hierarchy,  as more fully described in Note  2, ‘‘Significant Accounting
Policies—Revenue Recognition,’’ in our consolidated financial statements.

Should changes in conditions cause management to determine these criteria  are not met  for
certain future transactions, revenue recognized for  any reporting  period could be adversely  affected.
Failure to obtain anticipated orders due  to  delays or  cancellations of  orders  could  have a material
adverse effect on our revenue. In addition, pressures from  customers to reduce  our  prices or to modify
our  existing sales terms may have a material adverse  effect on our  revenue in  future periods.

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
higher  than published specifications, (1)  the products are tested  and  accepted by the customer at our
site or the customer accepts the results of our  testing program prior  to  shipment to the customer, or
(2) the revenue is deferred until customer  acceptance  occurs.

Sales to end-users in the scientific market typically  require installation and, thus, involve
post-delivery obligations; however our  post-delivery  installation  obligations are not essential to the
functionality of our products. We defer  revenue related  to installation  services until completion of these
services.

For most products, training is not provided; therefore,  no post-delivery training  obligation exists.

However, when training is provided to  our customers,  it is typically priced separately and  recognized as
revenue as these services are provided.

For multiple element arrangements which include extended maintenance contracts,  we allocate  and

defer the amount of consideration equal to the separately stated  price and  recognize revenue on a
straight-line basis over the contract period.

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

71

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.

Goodwill is tested for impairment on  an annual  basis and between annual tests in certain

circumstances, and written down when impaired (See Note 7, ‘‘Goodwill  and Intangible Assets’’  in the
Notes to Consolidated Financial Statements). 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.

In January 2017, the FASB issued amended guidance that  simplifies  the subsequent measurement

of goodwill by eliminating Step 2 from  the goodwill impairment test. Under the amendments  in this
update, an entity should perform its annual, or interim,  goodwill  impairment test  by  comparing the fair
value of a reporting unit with its carrying  amount  and recognize  an impairment charge for the amount
by which the carrying amount exceeds the  reporting  unit’s fair  value. The  new standard will become
effective for our fiscal year beginning October  2, 2021. We elected to early adopt  the standard in  the
fourth quarter of fiscal 2017 for our  fiscal 2017  impairment tests.

In fiscal  2018, 2017 and 2016, we conducted a qualitative assessment of the goodwill  in the OLS
reporting unit during the fourth quarter of each fiscal year 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 amount.  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 prior  year 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 2018, 2017 or 2016. As  such, it was not necessary to perform the goodwill
impairment test at that time in any of  those fiscal years.

In fiscal  2018, we conducted a qualitative assessment  of the goodwill in the  ILS reporting unit
during the fourth quarter of fiscal 2018 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 amount. 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

72

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 prior year between estimated fair value and the carrying value of ILS. Based  on our assessment,
goodwill in the ILS reporting unit was not impaired as of the first day of the fourth  quarter  of  fiscal
2018 and as such, it was not necessary to perform  the goodwill  impairment test  at that time.

For our ILS reporting unit, we elected to bypass  the qualitative assessment in fiscal 2017  and 2016
and proceeded directly to performing the  first step of goodwill impairment. Accordingly,  we performed
the Step 1 test during the fourth quarter  of fiscal 2017 and 2016. We  determined  the fair value of the
reporting unit for the Step 1 test using a  50-50% weighting of the Income (discounted  cash flow)
approach and Market (market comparable)  approach. 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. This rate of return or cost  of  capital is weighted based on  the capitalization of
comparable companies. The Market approach determines fair  value by  comparing the reporting units to
comparable companies in similar lines  of  business  that are publicly traded. 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. These multiples are  then applied to the reporting
unit’s operating results to obtain an estimate of fair value. Each  of  these two  approaches  captures
aspects of value in each reporting unit.  The Income approach captures our expected future
performance, and the Market approach captures  how investors view the  reporting units through  other
competitors. We believe these valuation  approaches are proven valuation techniques and methodologies
for our  industry and are widely accepted by investors. As neither  was  perceived by us to deliver any
greater indication of value than the other,  and  neither approach individually computed a fair  value less
than the carrying value of the segment, we  weighted  each  of  the approaches equally. Management
completed and reviewed the results of the  Step 1 analysis and concluded that an impairment  charge
was not required as the estimated fair value  of the ILS reporting unit was substantially  in excess of its
carrying  value.

At September 29, 2018, we had $442.9  million  of  goodwill ($100.7  million  OLS and $342.2 million
in ILS), $142.3 million of purchased  intangible assets and $311.8 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.

73

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 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 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 2018, we increased our valuation  allowance  on deferred  tax  assets by $5.0  million to
$33.7 million, primarily due to the increase  in California research and development tax credits and net
operating losses generated from Rofin  China which are not expected to be recognized. The Company
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. As of September 29, 2018,
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. However, we  have
reevaluated our historic assertion as a  result  of  the enactment of the Tax Act and no longer consider
certain historic foreign earnings to be indefinitely reinvested in  our foreign subsidiaries. As  a result of
this  change in assertion, we recorded a $13.7 million tax expense for foreign withholding taxes and  state
income taxes in the fourth quarter of fiscal 2018.  We will continue  to  assert an  indefinite reinvestment
of certain historic foreign earnings and profits of $488.0 million and may be subject  to  additional
foreign withholding taxes and certain  state income taxes  upon repatriation. We also have not
recognized any deferred taxes for outside  basis differences in our 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.

74

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 2018 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 2018 year-end, the fair value  of  our available-for-sale debt securities  was  $0.1 million, all

of which was classified as short-term investments. At fiscal 2017 year-end, the fair value  of  our
available-for-sale debt securities was  $69.5  million,  $37.0 million of which  was  classified as cash and
cash equivalents and $32.5 million of which was classified as  short-term investments.  There were  no
gross  unrealized gains and losses on  available-for-sale debt securities at fiscal  2018 or 2017  year-end.

We  are exposed to market risks related  to  fluctuations in  interest  rates related to our Euro Term
Loan. As of September 29, 2018, we owed  $430.6 million on  this  loan with an  interest  rate of 2.75%.
We  performed a sensitivity analysis on the  outstanding portion  of our  debt obligation  as of
September 29, 2018. 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
September 29, 2018.

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,  the Japanese Yen, the South Korean  Won and the  Chinese Renminbi.  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, Singapore Dollars, Malaysian Ringgit,
Swiss Franc and Canadian Dollar. 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, 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 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 trading purposes.

On occasion, we enter into currency  forward exchange  contracts to hedge specific anticipated
foreign currency denominated transactions generally expected to occur within the next  12 months.
These cash flow hedges are designated  for hedge  accounting treatment  and  gains and  losses on  these
contracts are recorded in accumulated other comprehensive income in  stockholder’s  equity and
reclassified into earnings at the time that  the related  transactions being hedged are recognized  in
earnings. See Note 6, ‘‘Derivative Instruments and Hedging Activities’’ to our Consolidated Financial
Statements under Item 15 of this annual  report.

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

75

these strategies will be effective or that  transaction 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.

At September 29, 2018, approximately  $215.7 million of our cash, cash  equivalents and short-term

investments were held outside the U.S.  in  certain of  our foreign operations, $191.2 million of which  was
denominated in currencies other than the U.S. dollar.

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.

The following table provides information about our foreign exchange forward  contracts at
September 29, 2018. The table presents  the weighted average  contractual  foreign currency exchange
rates, the value of the contracts in U.S. dollars at the  contract exchange rate as of the  contract maturity
date  and fair value. The U.S. fair value  represents  the fair value of  the contracts  valued at
September 29, 2018 rates.

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
September 29, 2018, 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 September 29, 2018. The effectiveness of our internal control over financial reporting as
of September 29, 2018 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

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 (‘‘GAAP’’). Because  of its
inherent limitations, internal control over  financial reporting  may  not prevent or  detect  misstatements.
Also, projections of any evaluation of effectiveness for 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.  Our internal control  over  financial  reporting is
designed to provide reasonable assurance  regarding  the reliability of financial reporting  and the
preparation of the financial statements for  external purposes  in accordance with  GAAP. Our  internal
control over financial reporting includes those policies and procedures that:

(i) pertain to the maintenance of records  that, in reasonable detail, accurately and fairly reflect

the transactions and dispositions of our assets;

(ii) provide reasonable assurance that transactions are recorded  as necessary to permit

preparation of financial statements in accordance with generally accepted accounting
principles, and that our receipts and expenditures are being made only in  accordance  with
authorizations of our management and directors; and

(iii) provide reasonable assurance regarding prevention or timely detection of  unauthorized

acquisition, use, or disposition of our assets  that could  have a material  effect  on the financial
statements.

77

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

In November 2016, we completed the acquisition of Rofin-Sinar  Technologies, Inc.  (‘‘Rofin’’). We

continue to integrate Rofin into our systems and control environment as of  September 29, 2018. We
believe that we have taken the necessary  steps to monitor and maintain appropriate internal control
over financial reporting during this integration. 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 September 29, 2018.

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 September 29,  2018, 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 September 29,  2018, 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 September 29, 2018, of the Company and  our  report dated November  27, 2018, 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.

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  2018 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 September 29, 2018 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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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

Opinion on the Financial Statements

We  have audited the accompanying consolidated balance sheets of Coherent, Inc.  and its
subsidiaries (the ‘‘Company’’) as of September  29, 2018 and September 30, 2017, and the related
consolidated statements of operations, comprehensive  income, stockholders’ equity, and  cash flows for
each  of the three years in the period  ended  September 29, 2018  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 September 29,  2018 and  September 30,
2017, and the results of its operations and its cash flows for each of the three years in the period ended
September 29, 2018, 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 September 29, 2018, based on the criteria established  in Internal  Control—Integrated  Framework
(2013) issued by the Committee of Sponsoring Organizations  of  the Treadway Commission and  our
report dated November 27, 2018, 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.

We  have served as the Company’s auditor since  1976.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. DESCRIPTION OF BUSINESS

Founded in 1966, Coherent, Inc. provides lasers, laser-based  technologies and laser-based system

solutions in a broad range of commercial,  industrial  and scientific research applications. Coherent
designs, manufactures, services and markets  lasers and related  accessories for  a diverse group of
customers. Headquartered in Santa Clara, California,  the Company has  worldwide operations  including
research and development, manufacturing,  sales,  service  and  support capabilities.

2. SIGNIFICANT ACCOUNTING POLICIES

Fiscal Year

Our fiscal year ends on the Saturday  closest to September 30. Fiscal years 2018,  2017 and 2016
ended on September 29, 2018, September  30, 2017 and October  1, 2016, respectively, and  are referred
to in these financial statements as fiscal  2018, fiscal 2017, and  fiscal  2016 for  convenience. Fiscal 2018,
2017 and 2016 include 52 weeks. The fiscal years of the majority  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 November 7, 2016, we acquired Rofin-Sinar Technologies, Inc. and  its  direct and indirect
subsidiaries (‘‘Rofin’’). On March 8,  2018, we acquired privately  held O.R. Lasertechnologie GmbH and
certain assets of its U.S.-based affiliate (collectively ‘‘OR  Laser’’). The significant accounting policies of
Rofin and OR Laser have been aligned  to  conform  to  those  of  Coherent, and  the consolidated
financial statements include the results  of Rofin  and OR Laser as of  their acquisition dates.

NOTES TO CONSOLIDATED FINANCIAL  STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES  (Continued)

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  2018 year-end, cash and cash equivalents included cash  and
money market funds.

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 2018 year-end,
the majority of our short-term investments were in  U.S. Treasury and agency  obligations. Cash
equivalents and short-term investments  are  maintained with several  financial institutions and may
exceed the amount of insurance provided  on such balances. At September 29, 2018,  we held  cash and
cash equivalents and short-term investments  outside the  U.S.  in certain of our foreign operations
totaling approximately $215.7 million, $191.2 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 16.4% and 19.0% of accounts receivable at fiscal 2018  and  fiscal 2017 year-end,
respectively. We had another customer  who  accounted for  16.7% and  10.0% of accounts receivable at
fiscal 2018 and fiscal 2017 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 and Canadian Dollar. 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. 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

97

2. SIGNIFICANT ACCOUNTING POLICIES  (Continued)

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  2018 year-end, gross expected  future cash flows of
$6.6 million would be required to fulfill these  obligations.

At September 29, 2018, $1,273 and $4,529 of the asset retirement  liability  are included in Other
current liabilities and Other long-term  liabilities on our consolidated balance sheets, respectively. At
September 30, 2017, the asset retirement liability is included in Other  long-term  liabilities 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 2018 and 2017, we recorded  impairment charges  of  $0.3 million and  $2.9 million, respectively,
on the net assets of several entities acquired in  the acquisition of Rofin to write them  down  to  reflect
our  best estimate of fair value, less costs to sell (See Note 18, ‘‘Discontinued Operations and  Sale  of
Assets  Held for Sale’’). In addition, in  fiscal  2018, we recorded an impairment  charge of  $0.5 million to
reduce the carrying value of a building  to  its  fair value. In fiscal 2016,  there were  no significant asset
impairments  recorded.

Goodwill

Goodwill is tested for impairment on  an annual  basis and between annual tests in certain
circumstances, and written down when impaired (See Note 7, ‘‘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 both our fiscal 2018  and 2017  annual testing,
we performed a qualitative assessment of  the goodwill  for  our OLS reporting  unit using the opening
balance sheet as of the first day of the  fourth quarter and noted no impairment. For the ILS  reporting
unit, in our fiscal 2018 annual testing, we  performed a qualitative assessment of the  goodwill using  the
opening balance sheet as of the first day of  the fourth  quarter and noted  no impairment. For the ILS
reporting unit, in our fiscal 2017 annual testing, we  elected to bypass  the qualitative  assessment and
proceed directly to performing the goodwill  impairment  test.  Accordingly, we  performed  our
impairment test using the opening balance sheet  as of the  first day of the fourth quarter and noted no
impairment in fiscal 2017.

Intangible  Assets

Intangible assets, including acquired existing technology, customer relationships,  trade name and

patents are amortized on a straight-line basis over  their  estimated useful lives, currently  3 year to
15 years (See Note 7, ‘‘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. 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.

Loss Contingencies

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

When a sales arrangement contains multiple elements, such as products and/or services, we
allocate revenue to each element based on  a selling  price hierarchy. Using the  selling price  hierarchy,
we determine the selling price of each deliverable using vendor specific objective evidence (‘‘VSOE’’),
if it  exists, and otherwise third-party  evidence (‘‘TPE’’). If neither VSOE nor TPE  of selling  price
exists, we use estimated selling price  (‘‘ESP’’).  We  generally  expect  that we will not be able to establish
TPE due to the nature of the markets in which we compete,  and, as such, we  typically will  determine
selling price using VSOE or if not available,  ESP.

Our basis for establishing VSOE of a deliverable’s selling price consists of standalone sales

transactions when the same or similar  product or service is sold separately. However,  when services are
never sold separately, such as product installation services, VSOE  is based on the product’s estimated

101

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL  STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES  (Continued)

installation hours based on historical experience multiplied by  the standard service billing rate. In
determining VSOE, we require that a substantial majority of the selling price for a product or service
fall within a reasonably narrow price  range, as defined by us. We also consider  the geographies  in
which  the products or services are sold,  major product and service groups,  and other  environmental
variables in determining VSOE. Absent  the existence of  VSOE and TPE, our determination  of a
deliverable’s ESP involves evaluating several factors based on the specific facts  and circumstances  of
these arrangements, which include pricing  strategy and policies driven  by  geographies, market
conditions, competitive landscape, correlation between  proportionate selling price and list price
established by management having the  relevant authority,  and  other environmental variables in which
the deliverable is sold.

For multiple element arrangements which include extended maintenance contracts,  we allocate  and

defer the amount of consideration equal to the separately stated  price and  recognize revenue on a
straight-line basis over the contract period.

We  recognize revenue when all four  revenue recognition criteria  have been met: persuasive
evidence of an arrangement exists, the  product has  been delivered or  the  service  has been  rendered,
the price is fixed or determinable and collection is reasonably  assured. Revenue from  product sales is
recorded  when all of the foregoing conditions are  met and risk of loss and title passes  to  the customer.
Sales to customers are generally not subject  to  any  price protection  or  return rights.

The majority of our sales are made to original equipment manufacturers (‘‘OEMs’’), distributors,

representatives and end-users in the non-scientific market.  Sales  made to these customers do not
require installation of the products by  us and are not subject to other post-delivery obligations,  except
in occasional instances where we have  agreed to perform  installation  or provide training. In those
instances, we defer revenue related to  installation  services or training  until these  services have been
rendered. We allocate revenue from multiple element arrangements to the various  elements based upon
relative fair values.

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
higher  than published specifications, (1)  the products are tested  and  accepted by the customer at our
site or the customer accepts the results of our  testing program prior  to  shipment to the customer, or
(2) the revenue is deferred until customer  acceptance  occurs.

Sales to end-users in the scientific market typically  require installation and, thus, involve
post-delivery obligations; however, our  post-delivery  installation  obligations are not essential to the
functionality of our products. We defer  revenue related  to installation  services until completion of these
services.

For most products, training is not provided; therefore,  no post-delivery training  obligation exists.

However, when training is provided to  our customers,  it is typically priced separately and  is recognized
as revenue as these services are provided.

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

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 $3.2  million,  $2.9 million and  $2.7 million were  offset
against research and development costs in fiscal  2018, 2017 and 2016,  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 (net of tax) at fiscal 2018  year-end  is substantially comprised  of
accumulated translation adjustments  of  $(1.8) million and deferred actuarial gains on pension  plans of
$4.6 million. Accumulated other comprehensive income  (net  of  tax)  at fiscal 2017  year-end is
substantially comprised of accumulated translation adjustments  of  $16.3 million and  deferred actuarial
gains on pension plans of $3.6 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 stock  options, restricted  stock awards and  stock  purchase  plan
contracts, using the treasury stock method.

Stock-Based  Compensation

We  recognize compensation expense  for all shared 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. 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.

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. Custom duties
billed to customers are recorded in cost  of sales.

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,

104

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL  STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES  (Continued)

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, 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. However, we  have

reevaluated our historic assertion as a  result  of  enactment  of the Tax Cuts  and Jobs  Act (the ‘‘Tax
Act’’) and no longer consider certain historic foreign earnings to be indefinitely reinvested in  our
foreign subsidiaries. As a result of this change  in assertion, we recorded a  $13.7 million tax  expense for
foreign withholding taxes and state income taxes in the fourth quarter of fiscal 2018. We will continue
to assert an indefinite reinvestment of  certain historic foreign earnings  and  profits of  $488.0 million and
may be subject to additional foreign  withholding taxes and certain state  income  taxes upon  repatriation.
We  also have not recognized any deferred taxes  for outside basis differences in  our  foreign subsidiaries.

Adoption of New Accounting Pronouncements

In October 2016, the Financial Accounting Standards Board (the ‘‘FASB’’) issued  amended
guidance that improves the accounting  for the income tax consequences of  intra-entity transfers  of
assets other than inventory. Under the  new guidance,  an entity should recognize the income tax
consequences of an intra-entity transfer of an asset other than  inventory when  the transfer occurs.  The
new standard is required to be adopted  in the first quarter  of  our fiscal  2019. We  elected  to  early adopt
the amended guidance in the first quarter  of fiscal 2018.  The  effect of adoption is a decrease in our
opening retained earnings by $6.1 million with  a comparable decrease to our non-current  prepaid
income tax balance.

In March 2016, the FASB issued amended  guidance that simplifies several  aspects of the

accounting for employee share-based  payment transactions, including the  accounting for  income  taxes,
forfeitures and statutory tax withholding  requirements,  as well  as classification in the  statement  of cash
flows. Under the new guidance, an entity recognizes  all  excess  tax  benefits and tax  deficiencies as
income tax expense or benefit in the income  statement. This change eliminates  the notion of the

105

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL  STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES  (Continued)

additional paid-in capital pool and significantly  reduces the complexity and cost of accounting for
excess tax benefits and tax deficiencies. Upon our adoption in  the first quarter of fiscal 2018,  we
recognized a windfall tax benefit as a cumulative effect adjustment increase to our opening retained
earnings of $19.8 million together with a comparable  increase in deferred tax assets. With adoption
occurring at the beginning of fiscal 2018, we  recognized excess tax benefits  from stock award exercises
and restricted stock unit vesting as a  discrete tax benefit, which reduced the provision for income taxes
for fiscal 2018 by $12.8 million. The adoption  also changed the calculation of fully diluted  shares
outstanding for fiscal 2018. The excess  tax  benefits have been excluded from  the calculation  of assumed
proceeds in our calculation of diluted weighted  average shares under the  new standard. Our diluted
weighted average shares outstanding for  fiscal 2018 increased  by 71,010  shares due to adoption  of  the
new standard. Additionally, effective in the  first quarter  of fiscal 2018, excess  tax benefits are classified
as an operating activity in the statement  of cash flows instead of as a financing activity where they  were
previously presented. We adopted this  guidance on a prospective basis and, accordingly, prior periods
have not been adjusted. We have elected  to not estimate forfeitures expected to occur to determine the
amount of compensation cost to be recognized in each period. The remaining provisions  of this
amended guidance did not have a material  impact on our consolidated financial statements.

Recently Issued Accounting Pronouncements

In August 2018, the Securities and Exchange  Commission (‘‘SEC’’) adopted amendments to certain

disclosure requirements in Securities  Act  Release No. 33-10532, Disclosure Update and Simplification.
The amendments became effective on  November  5, 2018.  The  SEC staff subsequently  indicated that it
would not object if a filer’s first presentation of changes  in shareholders’  equity  is included in its
Form 10-Q for the quarter that begins after the final rule’s effective  date. Among the  amendments is
the requirement to present the changes in  shareholders’ equity in  the interim financial statements
(either in a separate statement or footnote) in  quarterly reports on Form  10-Q.  The analysis  should
present  a reconciliation of the beginning  balance  to  the ending balance of  each  period for which  a
consolidated statement of operations  is  required to be filed.  We will  include the first presentation of
changes in stockholders’ equity on Form 10-Q  in our first quarter of fiscal 2019.

In August 2018, the FASB issued amended  guidance to align the requirements for capitalizing
implementation costs incurred in a hosting arrangement that is a service contract with the requirements
for capitalizing implementation costs  incurred to develop or obtain  internal-use software  (and hosting
arrangements that include an internal  use  software license). The accounting  for the  service  element of a
hosting arrangement that is a service contract is not affected by the amendments.  According to the
amendments, the entity shall determine  which implementation costs to capitalize as  an asset related to
the service contract and which costs to  expense. It  requires  the entity (customer) to expense the
capitalized implementation costs of a hosting arrangement that  is a service  contract over  the term of
the hosting arrangement. The new standard  will become effective for  our fiscal 2021, which begins on
October 4, 2020. We are currently assessing the impact of  this  amended guidance.

In August 2018, the FASB issued amended  guidance to modify the  disclosure requirements  for
defined benefit pension plans and other postretirement plans. The new standard  will  become effective
for our  fiscal 2021, which begins on October 4,  2020. We are  currently assessing the impact of this
amended  guidance.

2. SIGNIFICANT ACCOUNTING POLICIES  (Continued)

In August 2018, the FASB issued amended  guidance to modify the  disclosure requirements  on fair

value measurements in Topic 820, Fair  Value Measurement, based  on the concepts in  the Concepts
Statement, including the consideration of  costs and  benefits. The new standard will become effective
for our  fiscal 2021, which begins on October 4,  2020. We are  currently assessing the impact of this
amended  guidance.

In June 2018, the FASB issued amended guidance to expand the scope of  Topic 718 to include

share-based payment transactions for acquiring goods and services from non-employees. The
amendments specify that Topic 718 applies to all share-based payment transactions  in which  a grantor
acquires goods or services to be used or consumed  in a grantor’s  own operations by issuing share-based
payment awards. The new standard will become effective for our fiscal 2020,  which begins on
September 29, 2019. We are currently  assessing the  impact of  this amended guidance.

In February 2018, the FASB issued amended  guidance to allow a  reclassification  from accumulated

other comprehensive income to retained earnings for stranded tax effects resulting  from the Tax Cuts
and Jobs  Act. Consequently, the amendments eliminate the stranded tax effects resulting from the Tax
Cuts and Jobs Act and will improve the  usefulness of  information reported  to  financial  statement  users.
However, because the amendments only relate to the reclassification of the income tax  effects of the
Tax  Cuts and Jobs Act, the underlying  guidance that requires  that the effect of a change  in tax  laws  or
rates be included in income from continuing operations is not affected. The amendments also require
certain disclosures about stranded tax  effects. The new standard will  become  effective  for our fiscal
2020, which begins on September 29,  2019. We are currently  assessing the impact of this amended
guidance.

In August 2017, the FASB issued amended  guidance to address the  current limitation on how an
entity can designate the hedged risk in  certain cash  flow and fair value  hedging relationships  pursuant
to U.S. GAAP. This amendment better aligns an  entity’s  risk management activities  and financial
reporting for hedging relationships through changes to both designation and  measurement guidance for
qualifying hedging relationships and  the presentation of hedge results.  The  amendment made  specific
improvements on hedge accounting for risk components in hedging relationships  involving nonfinancial
risk and interest rate risk for cash flow hedges of  forecasted  purchases or sales of a nonfinancial asset,
cash flow hedges of interest rate risk  of  variable-rate financial instruments and fair value hedges of
interest rate risk. Upon adoption, for  cash flow and  net investment hedges existing,  an entity should
apply  a cumulative-effect adjustment  related to eliminating the separate measurement of  ineffectiveness
to other comprehensive income with  a corresponding adjustment to the opening balance of retained
earnings as of the beginning of the fiscal year that an entity adopts the amendment.  The  amended
presentation and disclosure guidance  is  required  only  prospectively. The new standard  will  become
effective for our fiscal 2020 which begins on  September 29, 2019.  We are currently assessing the impact
of this amended guidance.

In February 2016, the FASB issued accounting guidance  that modifies  lease  accounting for  lessees
to increase transparency and comparability by recording lease assets and liabilities for  operating leases
and disclosing key information about  leasing arrangements.  The new standard will become  effective  for
our  fiscal 2020, which begins on September 29, 2019. We  will  adopt the new guidance  utilizing  the
modified retrospective transition method.  We have reviewed the requirements of this standard and have
formulated a plan  for implementation.  We  are currently working on accumulating a  complete
population of leases from all of our locations and have selected a  software repository to track all of our

lease agreements and to assist in the  reporting and disclosure requirements required  by  the standard.
We  will continue to assess and disclose the  impact that  this new  guidance  will  have on our consolidated
financial statements, disclosures and related  controls, when  known.

In May 2014, the FASB issued ASU  2014-09, Revenue from Contracts with Customers

(‘‘ASU 2014-09’’), which outlines a single, comprehensive  model for entities  to  use in  accounting for
revenue arising from contracts with customers. The core principle of ASU 2014-09 is to recognize
revenue when promised goods or services  are  transferred to customers  in an amount that reflects the
consideration that is expected to be received for those goods or services. ASU 2014-09 defines a
five-step process to achieve this core principle and, accordingly, we expect  more judgment  and
estimates may be required within the revenue recognition process  than is required  under the previous
revenue recognition standard, including  identifying performance  obligations in the  contract, estimating
the amount of variable consideration to include in the transaction  price and allocating  the transaction
price to each separate performance obligation. ASU 2014-09 is effective for us beginning on  the first
day of fiscal 2019,  which is September  30, 2018.  ASU 2014-09 permits two methods of  adoption:
retrospectively to each prior reporting  period presented (the full  retrospective method), or
retrospectively with the cumulative effect of  initially applying the guidance recognized at the date  of
initial application (the modified retrospective method). We elected to adopt ASU 2014-09  using  the
modified retrospective method and will  apply the standard  to  contracts  that are not completed  as of
September 30, 2018 and all new contracts  entered into by the  Company subsequent to September 30,
2018. All prior period financial statements  and disclosures  will be presented in accordance with
Topic 605.

We  have completed our analysis of open  revenue contracts as of  September 30, 2018.  We  have

concluded that the adoption of the new  standard will not have a material  impact  on the  timing or
amount of revenue recognized primarily  as  a result of  a majority of our sales of products and services
are not bundled and therefore revenue will be recorded  at the  point-in-time when  control  transfers,
which  reflects the same timing of revenue recognition under ASC 605.  In the preparation  for the
adoption of ASU 2014-09, we have implemented internal  controls to enable the  preparation of financial
information and related disclosures in accordance with  this standard.

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 material to our prior period  consolidated financial results.

The identifiable intangible assets are  being  amortized over  their respective preliminary useful lives
of 1 to 8 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 relative to identifiable intangible  assets relates to several
factors including: (1) potential buyer-specific synergies  related  to  the  development of new technologies
related primarily to the additive manufacturing 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.

We  expensed $0.6 million of acquisition-related  costs as selling, general and  administrative

expenses in our consolidated statement of operations  in fiscal 2018.

Fiscal 2017 Acquisitions

Rofin

On November 7, 2016, we completed  our  acquisition of Rofin pursuant to the Merger Agreement

dated March  16, 2016. Rofin was one  of  the world’s leading developers and manufacturers of
high-performance industrial laser sources and laser-based solutions and components. Rofin’s  operating
results have been included primarily  in our Industrial Lasers &  Systems segment.  See Note 16,
‘‘Segment and Geographic Information.’’

As a condition of the acquisition, we were  required  to  divest and hold separate Rofin’s low  power

CO2 laser business based in Hull, United  Kingdom (the ‘‘Hull Business’’), and  had reported  this
business separately as a discontinued operation  until its  divestiture. We  completed the  divestiture of the
Hull Business on October 11, 2017, after receiving approval for the terms of the sale from the
European Commission. See Note 18, ‘‘Discontinued Operations  and Sale of Assets  Held for Sale.’’

The total purchase consideration has  been allocated to the  tangible and identifiable intangible

assets acquired and liabilities assumed  based on a valuation  analysis.

The total purchase consideration allocated to net assets acquired  was  approximately  $936.3 million

and consisted of the following (in thousands):

The acquisition was an all-cash transaction at  a price of $32.50 per share of Rofin common stock.

We  funded the payment of the aggregate consideration with  a  combination of our available cash  on
hand and the proceeds from the Euro Term  Loan described in Note 9, ‘‘Borrowings.’’ The total
payment of $15.3 million due to the cancellation of options held by employees of  Rofin was allocated
between total estimated merger consideration  of  $11.1 million and post-merger  stock-based
compensation expense of $4.2 million  based on the portion of the total service period of the underlying
options that had not been completed  by the  merger date.

We  recognized a gain of $5.4 million in the  first quarter  of fiscal 2017 on the increase in fair  value

from the date of purchase for the shares  of Rofin we  owned  before  the acquisition.

Under the acquisition method of accounting, the total estimated acquisition consideration is
allocated to the acquired tangible and intangible assets and assumed  liabilities of Rofin based on  their
fair values as of the acquisition date.  Any  excess  of  the acquisition consideration over the  fair value  of
assets acquired and liabilities assumed  is allocated  to  goodwill. We concluded  that  all  such goodwill will
not be deductible for tax purposes.

The fair value write-up of acquired finished  goods and work-in-process  inventory  was $26.4 million,

which  was amortized over the expected period during which the acquired inventory was sold, or
6 months. Accordingly, for fiscal 2017,  we  recorded $26.4 million  of  incremental cost of  sales associated
with the fair value write-up of inventory  acquired in the merger with Rofin. The fair value write-up  of
inventory acquired was fully amortized  in  fiscal  2017.

The fair value write-up of acquired property, plant and  equipment of $36.0  million will be

amortized over the useful lives of the assets, ranging from 3 to 31  years.  Property, plant and equipment
is valued at its value-in-use, unless there was a known plan to dispose of  the asset.

The acquired existing technology, backlog, trademarks and patents  are  being amortized on a
straight-line basis, which approximates  the  economic use  of  the asset, over their  estimated useful lives
of 3 to 5 years, 6 months, 3 years, and 5  years, respectively. Customer relationships are being amortized
on an accelerated basis utilizing free  cash flows over periods  ranging from 5 to 10  years.  The  useful
lives of in-process research and development will be defined in the future upon further  evaluation of
the status of these applications. 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

NOTES TO CONSOLIDATED FINANCIAL  STATEMENTS (Continued)

3. BUSINESS COMBINATIONS (Continued)

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 relative to identifiable intangible  assets relates to several
factors including: (1) potential buyer-specific synergies  related  to  market opportunities for  a combined
product  offering; and (2) potential to  leverage our sales force  to  attract new customers  and revenue
and cross sell to existing customers.

In-process research and development (‘‘IPR&D’’) consists  of two projects that had  not  yet reached

technological feasibility as of the date  of  the acquisition. Acquired  IPR&D  assets are initially
recognized at fair value and are classified as indefinite-lived assets until  the successful  completion  or
abandonment of the associated research  and development efforts.  The  value  assigned to IPR&D was
determined by considering the value  of the products under development  to  the overall development
plan,  estimating the resulting net cash  flows from the  projects  when completed and discounting the  net
cash flows to their present value. During  the development  period, these assets  will  not  be  amortized as
charges to earnings; instead these assets will  be  subject to periodic impairment testing. Upon successful
completion of the development process for the acquired IPR&D projects, the assets would then  be
considered finite-lived intangible assets and amortization of the assets will  commence. One project was
completed in December 2017 and amortization for  that  project  began  in the quarter ended  March 31,
2018. The other project has not been completed as of September 29, 2018  and is not expected  to  be
completed in fiscal 2019.

We  expensed $17.6 million of acquisition-related  costs as selling, general and  administrative

expenses in our consolidated statements  of  operations during fiscal 2017.

None of the goodwill was deductible  for tax  purposes.

The results of this acquisition were included in our consolidated operations beginning on

November 7, 2016. The amount of continuing Rofin  net sales and  net  loss from  continuing  operations
included in our consolidated statements  of  operations for  fiscal  2017 was approximately $434.9  million
and $48.1 million, respectively.

The unaudited pro forma financial information above includes the net  income  of Rofin’s low

power CO2 laser business based in Hull, United  Kingdom, which is  recorded as a discontinued
operation in fiscal 2017. See Note 18, ‘‘Discontinued Operations  and Sale of Assets Held  for Sale.’’

The unaudited pro forma financial information above reflects the  following  material  adjustments:

• Incremental amortization and depreciation expense related to the  estimated  fair value  of
identifiable intangible assets and property, plant and equipment from the purchase price
allocation.

• The exclusion of amortization of inventory step-up to its estimated fair value  from fiscal 2017

and the addition of the amortization to fiscal  2016.

• The exclusion of revenue adjustments as  a result of  the reduction in customer  deposits and

deferred revenue related to its estimated  fair value from fiscal 2017  and the addition of these
adjustments to fiscal 2016.

• Incremental interest expense and amortization  of debt  issuance  costs related to our  Euro  Term

Loan and Revolving Credit Facility (as defined in  Note 9,  ‘‘Borrowings’’).

• The exclusion of acquisition costs incurred by  both  Coherent and Rofin  from fiscal 2017 and the

addition of these costs to fiscal 2016.

• The exclusion of a stock-based compensation  charge related to the acceleration of  Rofin  options

from fiscal 2017 and the addition of  this charge to fiscal  2016.

• The exclusion of a gain on business combination  for  our previously owned shares of  Rofin  from

fiscal 2017 and the addition of this gain  to  fiscal  2016.

• The exclusion of a foreign exchange  gain on  forward contracts related to our debt  commitment

and debt issuance from fiscal 2017 and the addition of this gain to fiscal 2016.

• The estimated tax impact of the above adjustments.

4. 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 September 29, 2018  and September 30, 2017,  we did  not  have any  assets
or liabilities valued based on Level 3  valuations.

We  measure the fair value of outstanding  debt obligations for disclosure purposes on a recurring

basis. As of September 29, 2018, the current and long-term portion  of long-term obligations of
$5.1 million and $420.7 million, respectively,  are reported at amortized  cost. As  of September 30,  2017,
the current and long-term portion of  long-term obligations of $5.1 million and $589.0 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 6, ‘‘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.

5. 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).

(1) Classified as short-term investments because these securities  are highly liquid and can  be  sold  at

any time.

During  fiscal 2018, we received proceeds totaling  $26.9 million from the sale of available-for-sale

securities and realized no gross gains  or losses. During fiscal 2017, we received proceeds totaling
$0.1 million from the sale of available-for-sale  securities and realized no  gross gains  or losses.

6. 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,  Japanese Yen, South Korean Won  and Chinese Renminbi (RMB). 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 the Company’s 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.

On August 1, 2016, we purchased forward contracts totaling 670.0 million Euros, with a value date
of November 30, 2016, to limit our foreign  exchange  risk related to the commitment of our Euro Term
Loan (denominated in Euros) in an amount of the Euro equivalent of $750.0  million to finance the
U.S. dollar payment for our acquisition  of  Rofin. In  the fourth quarter of fiscal 2016,  we recognized an
unrealized loss of $2.2 million on these forward  contracts.  In the  first quarter  of  fiscal 2017, we settled
these forward contracts at a net gain  of  $9.1 million, resulting in a realized gain of $11.3 million  in the
first quarter of fiscal 2017.

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  4, ‘‘Fair  Values.’’

During  fiscal 2018, 2017 and 2016, we recognized a loss of $5.5 million, a  gain of $17.8 million and
a loss of $10.5 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
the 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.

7. 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

117

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL  STATEMENTS (Continued)

7. GOODWILL AND INTANGIBLE ASSETS (Continued)

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.

As a result of the acquisition of Rofin  in the first quarter  of  fiscal  2017, we reorganized our  prior

two reporting segments (Specialty Laser  Systems and Commercial Lasers  and Components) into two
new reporting segments for the combined  company: OEM Laser Sources (‘‘OLS’’) and Industrial
Lasers  & Systems (‘‘ILS’’). This segment  reorganization was based upon the organizational structure  of
the combined company and how the chief operating  decision  maker (‘‘CODM’’) receives and utilizes
information provided to allocate resources and make  decisions.

In our fiscal 2018 annual testing, we performed a qualitative  assessment of the  goodwill  for our

OLS and ILS reporting units during the  fourth  quarter  of fiscal 2018 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 units exceeded  their  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 the  reporting unit including cost  factors and
budgeted-to-actual revenue results. We also considered our  market  capitalization, stock price
performance and the significant excess  between the  estimated  fair value and carrying value of the OLS
and ILS reporting units. Based on our assessment, goodwill  in the OLS and ILS reporting units was not
impaired as of the first day of the fourth  quarter of  fiscal  2018. As such, it was not necessary to
perform the goodwill impairment test  at that  time. Between the completion of our assessment and  the
end of the fourth quarter of fiscal 2018,  we noted no  indications  of  impairment or triggering  events
with either reporting unit to cause us to review goodwill  for potential impairment.

The changes in the carrying amount of goodwill  by segment  for  fiscal 2018 and 2017 are  as follows

$328.5 million at September 30, 2017, respectively. At both September  29, 2018 and September  30,
2017, the accumulated impairment loss for  the ILS reporting  unit was $13.0  million reflecting  an
impairment charge in fiscal 2009.

(2) Gross amount of goodwill for our  OLS  segment was $109.5  million and $110.9 million at

September 29, 2018 and September 30, 2017,  respectively. At both September 29, 2018  and

September 30, 2017, the accumulated impairment  loss for the OLS reporting unit was $8.7 million
reflecting impairment charges in fiscal 2003  and fiscal 2009.

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 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.

In fiscal  2018 and 2017, we did not have any impairment of  intangible assets  as a result of the

impairment  analysis.

For accounting purposes, when an intangible asset  is fully amortized, it is removed from the

disclosure  schedule.

The weighted average remaining amortization periods  for  existing  technology, customer lists  and
trade names are approximately 2.5 years, 6.9 years and 1.1 years, respectively. Amortization  expense for
intangible assets during fiscal 2018, 2017, and 2016 was $60.0 million, $60.6 million and $8.5 million,
respectively. The change in accumulated amortization  also  includes $2.6 million (decrease) and
$4.8 million (increase) of foreign exchange  impact for  fiscal 2018  and  fiscal  2017, respectively.

9. BORROWINGS

With the March 8, 2018 acquisition of OR  Laser,  we assumed  several  term loans having an
aggregate principal amount of $1.9 million as of March 31, 2018. In fiscal 2018,  after the acquisition
date,  we paid off $1.2 million of principal on these loans. The  remaining  aggregate  principal amount
was $0.6 million at September 29, 2018.

On November 4, 2016, we repaid the outstanding balance, plus  accrued interest, on  our former

domestic line of credit and terminated  the $50.0 million credit facility  with Union Bank  of California.
We  assumed two term loans having an  aggregated principal amount of $15.3 million as of November 7,
2016 and several lines of credit totaling  approximately $18.1  million with the completion of the Rofin
acquisition.

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 ‘‘Credit Agreement’’).  The 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 (‘‘Revolving Credit Facility’’) with a $30.0 million letter of credit sublimit and a $10.0 million
swing line sublimit. The Borrower may increase the aggregate revolving commitments or borrow
incremental term loans in an aggregate principal amount not to exceed the sum  of  $150.0 million and
an amount that would not cause the senior secured net leverage  ratio to be greater than  2.75 to 1.00,
subject to certain conditions, including  obtaining additional commitments  from the lenders  then party
to the Credit Agreement or new lenders.  On November  7, 2016, the Borrower borrowed the full
670.0 million Euros under the Euro Term  Loan and its proceeds were used to finance  the acquisition of
Rofin and pay related fees and expenses.  On November 7, 2016,  we also  used  10.0 million Euros of the
capacity  under the Revolving Credit  Facility  for the  issuance  of  a letter  of credit.

The terms of the Credit Agreement require the  Borrower to prepay the term loans in certain

circumstances, including from excess  cash  flow  beyond  a threshold amount,  from the receipt of
proceeds from certain dispositions or  from the incurrence of certain indebtedness, and from
extraordinary receipts resulting in net  cash proceeds in excess of $10.0  million  in any fiscal year. 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, at which time all outstanding  principal and accrued and unpaid  interest  on the Euro
Term Loan must be repaid.

In fiscal  2018 and fiscal 2017, we made voluntary principal payments of 135.0 million Euros and

150.0 million Euros, respectively, on the  Euro  Term Loan. As of September 29,  2018 and
September 30, 2017, the outstanding principal  amount  of the Euro Term Loan was  371.6 million Euros
and 513.3 million Euros, respectively. As of each of  September  29, 2018 and September 30, 2017,  the
outstanding principal amount of the Revolving Credit  Facility was  10.0 million Euro.

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  (the  ‘‘LIBOR’’) or (y) in  the case of calculations with

121

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. The applicable margin  for Euro Term Loan borrowed as  Eurocurrency Rate loans, is
3.50% initially, and following the first anniversary of the  Closing Date ranges from 3.50%  to  3.00%
depending on the consolidated total gross leverage ratio  at the time of determination. For Euro Term
Loan borrowed as Base Rate loans, the applicable margin  initially  is 2.50%, and following the first
anniversary of the Closing Date ranges from  2.50% to 2.00%  depending upon the consolidated total
gross  leverage ratio at the time of determination. The  applicable margin for  revolving loans borrowed
as Eurocurrency Rate loans, ranges from 4.25% to 3.75%, and for revolving loans borrowed as Base
Rate loans, ranges from 3.25% to 2.75%, in each case, based on the  consolidated  total gross leverage
ratio at the time of determination. 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). Interest periods  for Eurocurrency Rate loans  may
be, at the Borrower’s option, one, two,  three or six months.

On May 8, 2017, we entered into Amendment No.  1 and Waiver (the ‘‘Repricing Amendment’’)  to

the Credit Agreement to, among other  things, (i) reduce the applicable interest  rate margins with
respect to the Euro Term Loans to 1.25%  for Euro Term Loans maintained as  Base Rate loans and
2.25% for Euro Term Loans maintained as Eurocurrency  Rate  loans,  with stepdowns to 1.00% and
2.00%, respectively, available after May  8, 2018  if the  consolidated  total gross leverage ratio for
Coherent and its restricted subsidiaries  is less than 1.50:1.00 and  (ii) extend the  period during  which a
prepayment premium may be required  for a repricing  transaction until six months after  the effective
date  of  the Repricing Amendment. In  connection  with the  execution  of  the Repricing  Amendment, we
paid arrangement fees of approximately  $0.5 million in fiscal 2017,  as well as  certain  fees  and expenses
of the administrative agent and the lenders,  in accordance with the terms  of  the Credit Agreement.

As our consolidated total gross leverage ratio for Coherent and its restricted  subsidiaries  was  less
than 1.50:1.00 as of March 31, 2018, on  May 8,  2018, the applicable interest rate margins with respect
to the Euro Term Loans were stepped down to 1.00% for Euro Term Loans maintained as  Base Rate
loans and 2.00% for Euro Term Loans  maintained as  Eurocurrency Rate  loans.

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.

9. BORROWINGS (Continued)

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 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 the  Borrower, judgment defaults, and  bankruptcy  and insolvency
events. If an event of default exists, the lenders may  require  the immediate payment of all Obligations,
as defined in the Credit Agreement, and  may 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. We  were
in compliance with all covenants at September 29, 2018.

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 Repricing 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 prepayments. 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 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.

In fiscal  2018, we recognized interest expense of $14.9  million and amortization of  debt issuance

costs of $9.6 million in relation to the Euro Term  Loan. In fiscal 2017,  we  recognized interest expense
of $23.5 million and amortization of debt issuance costs  of $7.2 million in relation to the Euro Term
Loan.

Additional sources of cash available  to  us  were international currency lines of credit and bank
credit facilities totaling $26.5 million as  of September 29, 2018,  of which $18.5  million  was  unused and
available. These unsecured international facilities were used in Europe and Japan in fiscal 2018. As of
September 29, 2018, we had utilized $8.0 million of the  international credit facilities as guarantees in
Europe.

10. 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  September 29, 2018, we did
not have any material indemnification claims that  were probable  or reasonably possible.

Commitments

Rent expense was $22.1 million, $16.5 million and $12.6 million in fiscal  2018, 2017 and 2016,

respectively.

As of September 29, 2018, we had total purchase commitments  for inventory of approximately

$126.1 million and purchase obligations for  fixed  assets and  services of $15.6  million compared to
$180.0 million of purchase commitments  for inventory and  $23.9 million of purchase obligations for
fixed assets and services at September  30, 2017.  The inventory decrease  was  primarily  due  to  lower
commitments to support lower shipments of large ELA  tools  used  in the  flat  panel  display market. The
fixed assets and services decrease was  primarily due the  completion of expansion of  our manufacturing
capacity  in G¨ottingen,  Germany.

Contingencies

We  are subject to legal claims and litigation arising  in the ordinary course of business, such as
product  liability, employment or intellectual property claims, including, but not limited  to,  the matters
described below. On May 14, 2013, IMRA America (‘‘Imra’’)  filed a complaint for  patent  infringement
against two of our subsidiaries in the Regional Court of D¨usseldorf, Germany, captioned In re  IMRA
America Inc. versus Coherent Kaiserslautern GmbH  et.  al. 4b O  38/13. The complaint alleged that the
use of certain of the Company’s lasers infringed  upon EP Patent No.  754,103, entitled ‘‘Method For
Controlling Configuration of Laser Induced Breakdown  and  Ablation,’’ issued  November 5,  1997. The
patent, now expired in all jurisdictions, is owned  by  the University of Michigan  and licensed  to  Imra.
The complaint sought unspecified compensatory damages  and the  cost of court proceedings  and sought
to permanently enjoin the Company from infringing the patent in  the future.  Following the filing of the
infringement suit, our subsidiaries filed  a  separate nullity action with the Federal  Patent  Court in
Munich, Germany requesting that the  court  hold that  the patent was invalid  based on  prior art. On
October 1, 2015, the Federal Patent Court ruled  that the German portion of the  patent  was invalid.

10. COMMITMENTS AND CONTINGENCIES (Continued)

Imra appealed this decision to the Federal  Court  of  Justice, the  highest civil jurisdiction court in
Germany. On March 27, 2018, the Federal Court of Justice dismissed Imra’s appeal effectively ending
the case in favor of Coherent.

Although we do not expect that such legal 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.

The United States and many foreign  governments  impose tariffs  and duties  on the import and
export of certain products we sell. From  time to time our customs compliance, product classifications,
duty calculations and payments are reviewed or audited by government agencies.

On November 7, 2016, we entered into a  Credit Agreement, which was amended on May 8,  2017.

See Note 9, ‘‘Borrowings’’ for further  discussion of the issuance of the financing.

11. STOCK REPURCHASES

On February 6, 2018, our board of directors authorized a stock repurchase  program authorizing

the Company to repurchase up to $100.0 million of  our common  stock  from time to time  through
January 31, 2019. During fiscal 2018,  we repurchased  and retired 574,946 shares of outstanding
common stock under this program at  an average price of  $173.91  per  share for a total of
$100.0 million.

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.

12. EMPLOYEE STOCK AWARD AND  BENEFIT PLANS

Deferred  Compensation  Plans

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
plan,  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

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 a net  gain of $4.8  million in fiscal 2018, a
net gain of $5.0 million (including a $1.3  million  death benefit) in  fiscal  2017 and a net  gain of
$1.7 million in fiscal 2016. Changes in  the obligation to plan participants  are recorded as a component
of operating expenses and cost of sales; such amounts were a  loss of  $5.2 million  in fiscal 2018,  a loss
of $3.9 million in fiscal 2017 and a loss  of $2.1 million in  fiscal 2016. 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 2018, 2017,  and 2016 were
$5.6 million, $4.8 million and $4.1 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 2018, 2017  and 2016, a total of 66,099 shares, 95,678
shares and 141,340 shares, respectively, were  purchased by and  distributed to employees  at an average
price of $159.97, $81.82 and $46.81 per  share,  respectively.  At  fiscal  2018 year-end,  we had 358,783
shares of our common stock reserved  for  future issuance under the  plan.

Stock Award Plans

We  maintain a stock plan for which employees, service providers and non-employee  directors are

eligible participants. This plan, the 2011 Equity  Incentive Plan (the ‘‘2011 Plan’’),  provides 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 may  grant  options and awards
(time-based restricted stock units and performance restricted stock units) to purchase up  to  6,747,691
shares of common stock, of which 4,780,438 shares remained available  for  grant at  fiscal  2018 year-end.
At fiscal 2018 year-end, all outstanding stock  options and restricted stock  units have been issued under
plans approved by our shareholders.

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL  STATEMENTS (Continued)

12. EMPLOYEE STOCK AWARD AND  BENEFIT PLANS  (Continued)

Historically, option grants to employees vested  over the four years from the original grant  date.

Since adoption of the 2011 Plan, no stock options have been granted to employees.  Some vested
options made to one non-employee director  under a  prior stock plan  remain  outstanding.

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 or market-based conditions for  vesting.  Until restricted  stock  vests,  shares (including
those issuable upon vesting of the applicable restricted stock  unit) are 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.

• The performance restricted stock unit award grants are generally  either subject  to  annual vesting
over three years from the date of grant or 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 plan) compared  with
the performance of the Russell 1000  Index (or as otherwise  determined by the Compensation
and HR Committee).

Fair  Value of Stock Compensation

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 2018, 2017

and 2016 were estimated using the following weighted-average assumptions:

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  and could range  from no  units to a maximum of twice
the initial award units. The weighted average fair value for these performance  units was determined
using a Monte Carlo simulation model  incorporating  the following weighted average assumptions:

Risk-free interest rate . . . . . . . . . . . . . . . . . . . . . . .
Volatility . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

As a result of our acquisition of Rofin on November  7, 2016, we made a payment  of  $15.3 million

due to the cancellation of options held  by employees of  Rofin.  The payment was allocated between
total estimated merger consideration of  $11.1 million and post-merger  stock-based  compensation
expense of $4.2 million, recorded in the  first quarter  of fiscal 2017, based on  the portion of the  total
service period of the underlying options  that have not been completed  by the  merger  date.

During  fiscal 2018, $4.7 million of stock-based  compensation  cost was capitalized as part of

inventory for all stock plans, $4.4 million was amortized  into cost of sales and $1.5 million remained in
inventory at September 29, 2018. During  fiscal 2017, $3.6 million of stock-based  compensation  cost was
capitalized as part of inventory for all  stock plans, $3.3 million was amortized into cost of  sales and
$1.2 million remained in inventory at September  30, 2017.

At fiscal 2018 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 $36.0 million.
We  do not estimate forfeitures. 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.  During fiscal 2017, we recorded approximately $1.6  million of
excess tax benefits as cash flows from  financing activities. In fiscal 2016,  we  did not generate  any excess
tax benefits as cash flows from financing activities. We  adopted the  new accounting  standard on share-
based compensation in the first quarter  of  fiscal 2018. As a  result, we  recognized  excess tax  benefits
from stock award exercises and restricted  stock  unit vesting as a discrete tax  benefit, which  reduced  the
provision  for income taxes for fiscal 2018 by $12.8 million.

Stock Awards Activity

At fiscal 2018, 2017 and 2016 year-end, we had 24,000, 24,000  and 33,500 shares subject to vested

stock options outstanding. The vested  stock options at fiscal 2018  are  held by one non-employee
director.

(1) Service-based restricted stock units vested during each  fiscal year.  Performance-based

restricted stock units included at 100% of target  goal;  under the terms  of the awards, the
recipient may earn between 0% and 200% 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 131,000 in fiscal 2018,  131,000 in  fiscal  2017 and 89,000 in  fiscal
2016; tax payments made were $36.3 million,  $15.7 million and $5.4 million, respectively.

13. DEFINED BENEFIT PLANS

As a result of the Rofin acquisition,  we have 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. For these
pension plans, 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

131

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL  STATEMENTS (Continued)

13. DEFINED BENEFIT PLANS (Continued)

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.

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 2018,  2017 and 2016 (in thousands):

Service cost . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

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.

On December 22, 2017, the Tax Act was enacted.  The Tax  Act contains significant changes to U.S.
tax law, including lowering the U.S. corporate income tax rate to 21.0%  and implementing a  territorial
tax system. Since we have a September  year-end, the lower  U.S.  corporate income tax rate is phased in.
Our U.S. federal blended tax rate is approximately 24.5% for fiscal  2018 and  21.0% for  subsequent
fiscal years.

The reduction of the U.S. corporate income  tax rate adjusts our U.S. deferred tax assets and
liabilities to the lower U.S. federal tax rate  of 21.0%. There are also certain  transitional impacts  of  the
Tax  Act. As part of the transition to the  new territorial tax system,  the Tax Act imposes a one-time
deemed repatriation tax on our foreign subsidiaries’ historical earnings. These  transitional impacts

137

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL  STATEMENTS (Continued)

15. INCOME TAXES (Continued)

resulted in a provisional net charge of $26.7 million for  fiscal  2018. This is  comprised of an  estimated
deemed repatriation tax charge of $17.8  million  less a  previously  recorded deferred tax liability of
$20.3 million for anticipated repatriation of our investment in  a foreign subsidiary, plus  an estimated
deferred tax remeasurement charge of  $15.5 million and  an accrual for withholding taxes  and state
income taxes of $13.7 million on certain foreign earnings not considered permanently  reinvested.

The Tax Act changes are broad and complex. The final calculation of the Tax Act impact may
materially differ from the above provisional estimates.  Among  other  things, this  may be due to changes
in interpretations of the Tax Act, any  legislative  action to address questions  that  arise because  of the
Tax  Act, any changes in accounting standards for income taxes  or  related  interpretations in response to
the Tax Act, or any updates or changes to estimates  we have utilized to calculate the transitional
impacts. The Securities Exchange Commission  has issued guidance under Staff Accounting Bulletin
No. 118 directing taxpayers to record  impacts  of the Tax Act as ‘‘provisional’’ when  it does not have the
necessary information available, prepared  or analyzed (including computations)  in reasonable detail  to
complete the accounting under ASC  740.  The  guidance allows for a measurement period  of  up to one
year after the enactment date of the Tax Act to finalize the recording  of the related  tax impacts.  Most
of that activity has provisionally been  recorded in  our Consolidated  Financial Statements in the period
ended September 29, 2018, as Treasury  has not issued  final regulations with  respect to the new law.
The final regulation may change the provisional estimates. We recorded  what we believe to be a
reasonable  estimate.

The Tax Act also includes provisions  for Global  Intangible Low-Taxed Income  (‘‘GILTI’’) wherein

taxes on  foreign income are imposed  in  excess  of a deemed  return  on tangible  assets of foreign
corporations. In general, this income  will effectively  be  taxed at a 10.5% tax rate reduced by any
available current year foreign tax credits. This provision  is effective for taxable years beginning after
December 31, 2017, which is our fiscal 2019. Because of the  complexity of the new GILTI tax  rules, we
continue to evaluate this provision of  the  Tax  Act including  the associated forecast of GILTI and  the
application of ASC 740, Income Taxes.  Under U.S. GAAP,  we  are  allowed to make an accounting
policy choice of either (1) treating taxes due on future  U.S.  inclusions in  taxable  income  related to
GILTI as a current-period expense when incurred  (the ‘‘period cost  method’’)  or (2)  factoring such
amounts into our measurement of our deferred taxes  (the ‘‘deferred method’’). Our selection of an
accounting policy with respect to the  new  GILTI tax rules will depend, in part, on analyzing our global
income to determine whether we expect  to have  future U.S. inclusions in taxable income related to
GILTI and, if so, what the impact is  expected  to  be.  Whether we expect to  have future  U.S. inclusions
in taxable income related to GILTI depends  on not only our current structure and estimated future
results of global operations, but also  our intent and ability to modify our  structure. We are  currently  in
the process of analyzing our structure  and,  as a result,  are not yet  able  to  reasonably estimate the  effect
of this provision of the Tax Act. Therefore, we have not made any  adjustments related  to  potential
GILTI tax in our financial statements  and have not made  a policy  decision  regarding whether to record
deferred tax on GILTI. We will make the  accounting policy election after completion of the GILTI
analysis in the first quarter of fiscal 2019.

The effective tax rate on income from continuing operations  before  income taxes for fiscal 2018 of
31.6% was higher than the effective U.S.  federal blended rate of 24.5%. This was primarily due to the
Tax  Act’s one-time mandatory deemed  repatriation transition tax, the impact of income subject to
foreign tax rates that are higher than the U.S. tax rates, the  remeasurement of deferred tax assets and
liabilities based on the newly enacted U.S. federal tax rate of 21.0%,  an  accrual  for foreign  withholding

taxes and state income taxes on certain 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 (‘‘IRC’’) Section 162(m).  These amounts are  partially
offset by the excess tax benefits from stock award exercises and restricted stock unit  vesting, the  benefit
of foreign tax credits, the benefit of federal  research and development tax credits,  the benefit of a
domestic manufacturing deduction under  IRC Section 199 and the Singapore  tax exemption.

In October 2016, Coherent Singapore received an  amended Pioneer Status  tax exemption  from the

Singapore authorities effective from fiscal 2012  through fiscal 2021. The tax  holiday continues  to  be
conditional upon our meeting certain revenue,  business spending and employment thresholds.  The
impact of this tax exemption decreased Singapore income taxes  by approximately $2.5  million,
$1.1 million and $0.7 million in fiscal  2018, fiscal 2017 and fiscal 2016, respectively.

In determining our fiscal 2018 and 2017  tax provisions under ASC  Subtopic 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, foreign  tax attributes  and foreign
net operating losses at fiscal 2018 and  2017 year-ends.

During  fiscal 2018, we increased our valuation allowance on deferred  tax  assets by $5.0  million to
$33.7 million, primarily due to the increase in California research and development tax credits and net
operating losses generated from Rofin  China, which are not expected to be recognized. The Company
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. As of September 29, 2018,
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.

The net deferred tax asset is classified on  the consolidated balance sheets as follows

We  have various tax attribute carryforwards which include the following:

• Foreign federal and local gross net  operating loss carryforwards  are  $48.7 million, of which

$37.4 million have no expiration date  and  $11.3 million  have  various expiration  dates beginning
in fiscal 2019. Among the total of $48.7 million foreign  net operating loss  carryforwards, a
valuation allowance of $9.9 million has  been provided for certain  jurisdictions since the  recovery
of the carryforwards are uncertain. U.S.  federal and certain state  gross net operating loss
carryforwards are $8.3 million and $30.8 million,  respectively,  which were acquired from our
Rofin acquisition. A full valuation allowance  against certain other  state net operating losses of
$30.8 million has been recorded. California  gross net operating loss carryforwards  are
$7.4 million and are scheduled to expire  beginning  in fiscal 2032.

• U.S. federal R&D credit carryforwards of  $33.5 million  are  scheduled to expire  beginning  in
fiscal 2025. California R&D credit carryforwards of $30.3  million have no expiration date. A
total of $25.4 million valuation allowance,  before  U.S. federal benefit, has  been recorded against
California R&D credit carryforwards of  $30.3 million since  the recovery of the  carryforwards is
uncertain. Other states R&D credit carryforwards of $3.4 million are scheduled to expire
beginning in fiscal 2019. A valuation  allowance  totaling $2.8  million,  before  U.S. federal benefit,
has been recorded against certain state R&D  credit carryforwards of $3.4 million since  the
recovery of the carryforwards is uncertain.

• U.S. federal foreign tax credit carryforwards of $13.0 million are scheduled  to  expire beginning

in fiscal 2019.

We  adopted ASU No. 2016-09 in the  first quarter of fiscal 2018. As a  result of adopting the new

standard, excess tax benefits from equity-based compensation are now reflected in the  consolidated
statements of operations as a component  of the  provision for  income taxes. The adoption of ASU

140

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL  STATEMENTS (Continued)

15. INCOME TAXES (Continued)

No. 2016-09 resulted in a decrease in our provision for income  taxes of $12.8 million  for fiscal  2018
due to the recognition of excess tax benefits for options exercised  and the vesting  of equity awards.

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 2015 and 2010, respectively, are
closed to examination. In our other major foreign jurisdictions and our  major state jurisdictions, the
years prior to fiscal 2012 and 2014, 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 the U.S., a legacy Rofin entity is under audit for fiscal 2016. In  Germany, various Coherent  and
legacy Rofin entities are under audit  for the years 2010 through 2016.  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.

tax rate. Our total gross unrecognized  tax benefit was  classified as a long-term  taxes payable  in the
consolidated balance sheets after reduction  by  certain deferred tax assets.  We include interest and
penalties related to unrecognized tax  benefits within  the provision  for income taxes. As of
September 29, 2018, the total amount  of gross interest  and penalties  accrued was $4.4 million and it is
classified as long-term taxes payable in  the consolidated balance sheets.  As of  September 30, 2017, we
had accrued $2.8 million for the gross  interest and penalties and it  is classified  as long-term taxes

16. SEGMENT AND GEOGRAPHIC INFORMATION

As a result of the acquisition of Rofin-Sinar  Technologies Inc. (‘‘Rofin’’) in the first quarter of

fiscal 2017 (see discussion below), we reorganized our prior two reporting segments (Specialty Laser
Systems and Commercial Lasers and Components) into two new  reporting  segments for the combined
company: OEM Laser Sources (‘‘OLS’’)  and  Industrial Lasers  & Systems  (‘‘ILS’’). This segment
reorganization was based upon the organizational structure of the combined company and how  the
chief operating decision maker (‘‘CODM’’) receives and  utilizes information provided to allocate
resources and make decisions. Accordingly, our segment information was  restated retroactively in the
first quarter of fiscal 2017. 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 medical applications,  as well as  in scientific  research. Our ILS business segment
delivers high performance laser sources, sub-systems and  tools primarily used for  industrial laser
materials processing, serving important end markets like automotive, machine tool, consumer goods
and medical device manufacturing. Rofin’s operating  results have  been included primarily  in our ILS
segment. OR Laser’s operating results have been included in our ILS segment.

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 from continuing
operations is the measure of profit and  loss that our CODM uses  to  assess performance  and make
decisions. As assets are not a measure  used  to  assess the performance of the company  by  the CODM,
asset information is not tracked or compiled by segment and  is not available to be reported  in our
disclosures. Income from continuing  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  to  our  operating segments certain  operating expenses
which  we manage separately at the corporate level. These  unallocated costs  include stock-based
compensation and corporate functions (certain research and development, management, finance, legal

reconciliation of operating results. Management does not consider unallocated Corporate and other
costs in its measurement of segment  performance.

Major Customers

We  had one major customer who accounted for 25.8%, 22.9% and  13.1%  of consolidated revenue

during fiscal 2018, 2017 and 2016, respectively.  We had another major customer who  accounted for
16.4% of consolidated revenue during fiscal 2016.  Both customers purchased  primarily  from our  OLS
segment.

17. RESTRUCTURING CHARGES

In the first quarter of fiscal 2017, we began the  implementation of planned restructuring activities
in connection with the acquisition of Rofin. These  activities primarily relate to exiting  our legacy high
power fiber laser product line, change of  control payments  to  Rofin  officers, the exiting  of two  product
lines acquired in the acquisition of Rofin,  realignment of our  supply chain  due  to  segment
reorganization and consolidation of sales and distribution  offices as well as certain  manufacturing sites.
These activities resulted in charges primarily  for  employee termination, other exit related costs

144

associated with the write-off of property  and equipment and  inventory and early lease termination
costs.

The following table presents our current  liability  as accrued on our  balance sheets for restructuring

charges. The table sets forth an analysis  of  the components of the  restructuring charges and  payments
and other deductions made against the accrual for fiscal 2018 and fiscal 2017 (in thousands):

At September 29, 2018, $0.8 million of accrued severance related  costs  were included in other

current liabilities and are expected to  result  in cash expenditures through the fourth quarter of fiscal
2019. The current year severance related costs are primarily  comprised of severance pay for employees
being terminated due to the consolidation of certain manufacturing sites. The current year asset
write-offs are primarily comprised of write-offs  of  inventory and  equipment write-offs due to the
consolidation of certain manufacturing sites.  The severance related costs in fiscal 2017 are primarily
comprised of severance pay for employees being terminated due to the transition of activities out  of
Rofin including change of control payments  to  Rofin  officers and  the consolidation of  sales and
distribution offices. The asset write-offs in  fiscal  2017 are primarily comprised of write-offs of inventory
and equipment due to exiting our legacy high power fiber laser  product line and  inventory write-offs
due to the exit of other Rofin product  lines.

By  segment, $2.8 million and $11.4 million of restructuring  costs were incurred  in the ILS segment

and $1.1 million and $0.9 million were incurred in  the OLS segment in fiscal  2018 and  2017,
respectively. Restructuring charges are recorded in cost of sales,  research and development and selling,
general and administrative expenses  in our consolidated statements  of operations.

18. DISCONTINUED OPERATIONS AND SALE OF ASSETS HELD  FOR SALE

Discontinued  Operations

Discontinued operations are from the Hull Business  that  we acquired as  part of  our acquisition of

Rofin. As a condition of the acquisition,  we were  required to divest and hold  separate the  Hull
Business and reported this business separately as  a discontinued  operation until its divestiture. We
completed the divestiture of the Hull  Business on  October 11, 2017, after  receiving approval for  the
terms of the sale from the European Commission. As  a result  of the divestiture,  we recorded a  loss in
discontinued operations of $2,000 in  the first  quarter of fiscal 2018.  The  results from discontinued
operations in the first quarter of fiscal 2018 to the  date of  divestiture  (October 11,  2017)  were
immaterial and were not included in  our  consolidated  results of operations.

In the fourth quarter of fiscal 2017, management  decided  to sell several entities  that  we acquired

in the Rofin acquisition. Although the  sale was not completed as of the end of  fiscal  2017, we  recorded
a non-cash impairment charge of $2.9 million to operating expense in our results of  operations in the
fourth quarter of fiscal 2017 to reduce our carrying value  in  these  entities  to  fair value. On April  27,
