ANNUAL REPORT, PROXY STATEMENT & NOTICE OF ANNUAL MEETING

DEAR SHAREHOLDERS, 
CUSTOMERS & EMPLOYEES

At the outset of fiscal 2017, Coherent was poised to capitalize upon 
the  proliferation  of  OLED  technology  in  the  smartphone  industry 
and  the  completion  of  our  acquisition  of  Rofin-Sinar.    We  are 
delighted to report that the company delivered on both.  We further 
benefitted  from  strong  demand  across  the  remainder  of  our 
commercial  markets.  The  end  result  is  that  sales  nearly  doubled 
and  profits  (i.e.,  earnings  per  share)  roughly  tripled  compared  to 
the records set in the prior fiscal year.  We also set a new record for 
bookings,  taking  in  $2.03  billion  in  new  orders.    With  a  continued 
favorable  demand  environment,  these  orders  position  us  for 
another year of strong performance in fiscal 2018.

Microelectronics was our largest market in fiscal 2017.  The biggest 
storyline was the buildout of OLED production capacity to support 
the smartphone industry.  OLED production relies upon a variety of 
production  technologies  including  excimer  laser  annealing  of  the 
transistor  backplane  that  contributes  to  the  overall  clarity, 
brightness  and  electrical  efficiency  of  OLEDs.  We  have  built  an 
enviable  market  position  in  annealing  with  our  Vyper™-series 
excimer 
led  to 
lasers  and  Linebeam  optical  systems,  which 
significant  year-on-year  growth  for  systems  and  service.      The 
outlook for fiscal 2018 is equally bright, as we have entered the new 
fiscal  year  with  record  backlog  for  FPD  annealing  systems.  Panel 
manufacturers  are  shifting  their  focus  to  higher  throughput  tools 
utilizing Linebeam 1000 and Linebeam 1500 systems with average 
selling  prices  of  $10  million  and  $18.5  million,  respectively.    Each 
month, more systems transition from their initial warranty period to 
paid service.  These trends, along with a number of projected new 
OLED fabs, will require expansion of our production capacity for the 
second time in the last three years.

Our  lasers  are  playing  a  broader  role  in  smartphone  production 
than just annealing.  The emergence of new materials from flexible 
requires  new  manufacturing 
substrates 
to  glass  housings 
techniques 
that  provide  precision  and  speed  and  avoid 
post-processing  steps.    Lasers  satisfy  these  requirements  quite 
well,  leading  to  over  $70  million  of  orders  in  fiscal  2017  for  our

lasers  that  were  used

manufacturers  adopt  similar  materials  and  methods  in  the  upcoming  product

guidelines  for  the  CEO  and  instituting  stock  ownership  requirements  for  our  other 

releases.

senior executives. 

We trust that our shareholders were pleased with our record-setting performance in 

fiscal 2017. Among the metrics that benefitted from our financial results was free cash 

flow, which totaled more than $320 million. We used part of this total to voluntarily pay 

down  the  €670  million  loan  used  to  finance  the  Rofin  acquisition.  Within  the  fiscal 

year, we made principal payments of €150 million and an additional €75 million at the 

end  of  December  2017  for  a  total  of  €225  million.  In  other  words,  we  retired  about 

one-third of the debt in a little over one year.  We will continue to opportunistically use 

our excess cash (i.e., cash not reinvested in the business or used for strategic matters) 

to prepay the principal on this loan.

We  want  to  thank  our  customers,  shareholders  and  colleagues  across  the  globe  for 

their  trust  and  support.    We  look  forward  to  delivering  another  outstanding 

performance in fiscal 2018.

Respectuflly,

Investments in the semiconductor capital equipment market, where we are the leading 

supplier of lasers for inspection and metrology, have been rising steadily since 2010. 

Several  factors  have  contributed  to  the  growth,  including  increased  demand  for 

memory,  communications,  logic/processor  and  RF  chips  used  in  everything  from 

smartphones to IoT (Internet of things) devices, to cloud computing.  Chip supplies are 

still  constrained  in  certain  areas,  necessitating  further  capex  investments  across  the 

industry well into the current fiscal year.

A  little  more  than  one  year  ago,  we  completed  the  acquisition  of  Rofin-Sinar  in  an 

all-cash transaction.  The primary strategic objective of the transaction was to expand 

our  presence  in  the  materials  processing  market.    Our  revenue  for  components, 

lasers, subsystems and tools used in materials processing applications grew by more 

than  three-fold  compared  to  the  prior  fiscal  year  and  places  us  among  the  market 

leaders.  It is a very good first step that we have to build upon.  A second goal was to 

become one of the leading suppliers of high-power fiber lasers used in cutting, welding 

and additive manufacturing.  We focused our attention on ramping laser performance, 

collaborating  with  end  customers  on  applications,  re-engineering  the  supply  chain 

including  strategic  insourcing  and  expanding  our  customer  support  network.    These 

efforts were well-received by customers and we found ourselves capacity constrained 

by  the  end  of  fiscal  2017.  We  have  made  appropriate  investments  to  alleviate  the 

constraints and expect to grow fiber laser sales in fiscal 2018.  The final piece of the 

puzzle  was  to  revamp  our  approach  to  the  laser  systems  business  (i.e.,  end-user 

workstations).  We have started the transition from being a specialty tool supplier to a 

platform-based approach.  We believe this will drive greater value for customers and 

provide  us  with  broader  opportunities.  From  an  integration  standpoint,  we  are  on 

track to meet our timeline and synergy targets.  The success of this project is due to 

solid planning and execution by both legacy teams.

There have been positive developments in our OEM components and instrumentation 

business. 

In  prior  years,  the  majority  of  sales  came  from  medical  diagnostics  and 

therapeutics.  These  remain  important  areas  for  us,  but  other  opportunities  have 

grown organically and through the Rofin transaction.  One example is the sale of fiber 

and  diodes  to  other  fiber  laser  manufacturers.  Another  is  large  format  optics  for 

ground based telescopes.  Sales of lasers and subsystems into aerospace and defense 

applications  have  also  increased  as  the  U.S.  and  its  allies  deal  with  new  threats  and 

challenges around the world.

Coherent increased the size of its Board of Directors in 2017 with the appointment of 

Pamela Fletcher, vice president and global chief engineer for autonomous and electric 

vehicles at General Motors.  Ms. Fletcher’s domain expertise overlaps with several key 

areas  in  the  laser  industry,  including  cutting,  welding,  additive  manufacturing  and 

sensors.  Her  appointment  also  resulted  in  over  40%  of  our  independent  directors 

representing women and minorities.  Our commitment to good governance does not

General Information

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

or  other  questions,  please  contact  Investor  Relations  by

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

proposal  from  the  beneficial  owner.  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 Three and will have
the  same  effect  as  a  vote  ‘‘Against’’  these  proposals.  We
report  abstentions,  and  our
intend 
Compensation  and  H.R.  Committee  will  generally  view
abstentions  as  neutral  when  considering  the  results  of
Proposal Three. Broker non-votes represented by submitted
proxies  will  not  be  taken  into  account  in  determining  the
outcome of any proposal.

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

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

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  (December  15,  2018),  nor  earlier
than  the  close  of  business  on  the  75th  day  (November  15,
2018),  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 30, 2019 or

not  received  any  notice  regarding  any  such  matters  to  be
brought at the Annual Meeting.

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

Spotlight on Governance

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

*

Extended  stock  ownership  requirements  to  all  executive
officers and increased the stock ownership amount for our
CEO.

*

*

*

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;

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;

Age-based Board tenure guidelines; and

Board and CEO stock ownership requirements.

*

*

*

*

*

*

We are also announcing that Coherent is further extending its
governance  leadership  by  adopting  the  following  additional
governance  enhancements  (which  are  discussed  in  greater
detail in other sections of the proxy statement):

*

Amended our bylaws to provide for ‘‘proxy access’’ (effective
for our annual meeting to be held in calendar 2019); and

reflect 

Importantly,  the  Board  has  made  these  changes  at  the
recommendation  of  and  with  the  full  support  of  senior
management. These governance enhancements do not result
from  any  shareholder  proposals  related  to  them.  These
changes 
the  Board  and
the  commitment  of 
management to maintain common sense and industry-leading
governance  practices  and  policies  to  go  along  with  our
historical strong financial performance. This year we were also
happy to announce the appointment of Ms. Pamela Fletcher to
the  Board  of  Directors.  With  this  addition,  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 mid-term (which may vary from
time to time), which is reflected in the current composition of our
independent directors:

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

29%
43%
29%

Coherent has also undertaken several less publicized ‘‘green’’
initiatives, such as the installation of over 1200 solar panels on
our headquarter 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  (soon  to  be  10) electric  vehicle  charging
stations  that  our  employees  can  use  for  free.  Our  most
important environmental-related initiative, however, has been
our  energy-efficient  product  designs  over  the  years,  which
have  significantly  reduced 
the  amount  of  power  and
consumable materials needed to operate our products.

Contributing  to  the  community,  our  Santa  Clara  based
employees  raised  from  individual  employee  funds  over
$194,000  for  the  Second  Harvest  Food  Bank during  2017,
which is the equivalent of 388,000 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 2017.

recently  celebrated 

its  50th anniversary  of
Coherent 
incorporation,  and  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.
Ms. Fletcher, who was recommended to the Governance and
Nominating  Committee  by  the  search  firm  retained  by  the
committee, joined the Board during fiscal 2017 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.

Proposal One Election of Directors

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
three  (3)  times  by  unanimous  written  consent  during  fiscal
2017. 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  2017,  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
2017.

Audit Committee
The  Audit  Committee  consists  of  directors  James  (Chair),
Fletcher,  Rogerson  and  Skaggs.  The  Audit  Committee  held
ten  (10)  meetings  and  acted  one  (1)  time  by  unanimous
written consent during fiscal 2017. 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
responsible  for  approving  the  services  performed  by  our
independent  registered  public  accounting 
for
reviewing  and  evaluating  our  accounting  principles  and  our
system of internal accounting controls.

firm  and 

Committee held seven (7) meetings and acted one (1) time by
unanimous  written  consent  during  fiscal  2017.  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 other things, reviews and approves
our  executive  compensation  policies  and  programs,  and
makes  equity  grants  to  our  employees,  including  officers,
pursuant  to  our  equity  plan.  This  committee  has  the  sole
authority delegated to it by the Board to make employee equity
grants,  which  are  done  at  a  meeting  rather  than  by  written

recommendations to the Board on matters concerning director
nominations and elections, board committees and corporate
governance,  allocation  of  risk  oversight  amongst  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 2, 2017, all then-current members of the Board attended in person.

12

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.’’

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
those
recommended  by  a  stockholder,  as  well  as

• 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;

these

factors, among others, and does not assign any particular
factors.  The

weighting  or  priority 
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
minimum  qualifications 
the
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.

Our  corporate  governance  guidelines  require  that  upon  a
member  of  the  Board  turning  72  years  old,  he  or  she  shall

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
‘‘against’’  such  nominee  (with
exceed 
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
mail 
to  our  principal  executive  offices  (c/o  Corporate
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

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.

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.

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

Proposal One Election of Directors

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 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
the  stockholder
memo,  which  will  become  part  of 
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
seven of its eight members, or 88%, being independent.

The Role of the Board and its
Committees in Risk Oversight

risk  profile  and
The  Board  oversees  Coherent’s 
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.

those 

related 

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

15

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
the
Compensation  and  H.R.  Committee  agreed  with 
conclusion from the winter of calendar 2017 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.

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);

• 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 the Company, unless the other independent
directors consent;

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

The  Governance  and  Nominating  Committee  annually
reviews  Board  and  committee  compensation  with 
the
assistance of an independent compensation consultant, which
for  fiscal  2017  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 34) 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.  As  noted,  the  Board  is  compensated  with  a
combination of cash retainers and a fixed value of time-based
RSUs.  As  noted  elsewhere 
this  proxy  statement,
Compensia  has  not  provided  any  other  service  for  the
Company other than as directed by a committee of the Board.

Note that Ms. Fletcher’s retainer amounts are pro-rated for her time served during the fiscal year.

(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 2017. 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  2017.  Note  that
Ms. Fletcher’s stock awards are at a different value due to the difference in stock price on the date of her 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 2017 and reflecting the grants made to our non-employee directors during fiscal 2017 was as follows:

(b) These shares will vest on February 15, 2018.

(c) 50% of the shares will vest on each of June 30, 2018 and June 30, 2019.

(4) No stock options were granted to our non-employee directors during fiscal 2017. As of the end of fiscal 2017, Mr. Flatley
held outstanding stock options with respect to 24,000 shares and none of the other non-employee directors held any stock
options.

Proposal One Election of Directors

Our  stockholders  approved  the  adoption  of  our  2011  Equity
Incentive Plan (the ‘‘2011 Plan’’) at our annual meeting held in
March  2011  an  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
to  each
granting  each  year  without  any  discretion 
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  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  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.

Option Exercises and Stock Vested during Fiscal 2017
The table below sets forth certain information for each non-employee director regarding the exercise of options and the vesting of
stock awards during fiscal 2017, including the aggregate value realized upon such exercise or vesting.

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

18

Proposal One Election of Directors

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 29, 2018, 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  30,  2017,
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  2017  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.

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,
during fiscal 2017, other than Mr. Skaggs, who filed one late
Form 4 by one day due to our administrative error, all of our
officers,  directors  and,  to  our  knowledge,  greater  than  ten
complied  with  all  applicable

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.

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 2017 annual cash incentive plan was dependent upon corporate
achievement of two demanding performance targets: 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 2017.
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 2017 have the same measurement period as
in fiscal 2016 and 2015: a single vesting date three years from grant solely
dependent upon the performance of our common stock price measured against
the Russell 2000 Index, with target at meeting the index’s performance. We
historically have 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 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  carefully  considers 
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. All stockholders are invited to
express their views to the committee as described in this proxy
statement  under  the  heading  ‘‘Stockholder  Communication

with the Board of Directors.’’ The committee welcomes direct
stockholder feedback and considers such feedback as well as
the  results  of  our  historical  ‘‘say  on  pay’’  results  in  its
deliberations  on  executive  compensation.  We  strongly  urge
our stockholders to read this Compensation Discussion and

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
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,  so  that  even  though  the  Company’s
financial performance was solid in fiscal 2015, payouts were
not  as  robust.  In  fiscal  2017,  the  Company’s  financial
performance  resulted  in  maximum  payouts  under  our
annual cash incentive plan. Additionally, the performance of
the Company’s stock as measured against the Russel Index
resulted in maximum shares issued under the performance-
based RSUs, which vested at the maximum 200% payout.

• Tie  compensation 

to  performance  of 

the  core
business—Our fiscal 2017 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 2017.

• 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.

• 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 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  the  maximum  possible  payout,
Coherent’s  stock  has  to  outperform  the  index  by  at  least
50%.  Accordingly,  for  our  executives  to  achieve  the
committee’s  targeted  compensation,  Coherent’s  common
stock must at least meet the Russell Index. The chart below
illustrates this structure:

Compensation Discussion and Analysis

As a demonstration of how executive cash compensation is
tied to company performance, the cash compensation for our
CEO during fiscal 2017 at target, maximum and actual can
be illustrated as follows (dollars in thousands):

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 2017, include:

• We  have  minimum  share  ownership  requirements  for  our
Chief Executive Officer and members of the Board as well
as  Executive  Vice  Presidents  and  Senior  Vice  Presidents
who report to the CEO;

• Our performance-based RSU program is measured by the
Company’s  stock  price  achievement  against  the  Russell
Index  over  a  three  year  period,  which  the  committee
believes is a direct connection to long-term total stockholder
return;

• The committee is composed entirely of directors who satisfy
the  standards  of  independence  in  Coherent’s  Corporate
Governance Guidelines and Nasdaq listing standards;

• The committee makes decisions regarding Mr. Ambroseo’s

compensation without him present;

• Executive incentive compensation programs include limits
on  maximum  payouts  to  contain  the  risk  of  excessive
payouts;

• The  committee  utilizes  an  independent  compensation

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;

• Our  change-of-control  plan  provides  for  payment  only  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.

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

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,  and  providing  insights  regarding  our
employees  (executive  and  otherwise)  and  the  business
context for the committee’s decisions. NEOs attend portions of
committee meetings when invited by the committee, but leave

the  meetings  when  matters  potentially  affecting  them  are
discussed.

Role of the Committee’s Compensation Consultant
The  committee  utilizes  the  services  of  an  independent
fiscal  2017,  engaged
compensation  consultant  and 
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 

fiscal  2017

compensation; and

• Providing  further  insight  on  compensation  governance

trends.

Additionally,  in  fiscal  2017,  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.

Pay Positioning Strategy and
Benchmarking of Compensation
Philosophically  the  committee  initially  orients  target  total
compensation for our NEOs generally near the 50th percentile
of our peers (as measured by our designated peer group and,
when  applicable,  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  experience,  seniority,  skills,  knowledge,

Compensation Discussion and Analysis

performance  and  contributions  as  well  as  the  historical  pay
structure  for  each  executive.  These  factors  are  weighed
individually  by  the  committee  in  its  judgment,  and  no  single
factor takes precedence over others nor is any formula used in
making  these  decisions.  In  light  of  the  Company’s  strong
financial  performance  and  the  fact  that  the  committee  has
designed  the  significant  majority  of  the  Chief  Executive
Officer’s compensation to be at risk, including over 75% of his
long-term equity compensation (at maximum), for fiscal 2017
the committee asked Compensia to provide information at the
50th and 75th percentile for our Chief Executive Officer. Given
the  significant  ties  to  performance  and  with  such  a  large
percentage  of  his  potential  compensation  at  risk,  the
committee  oriented  his  compensation  target  closer  to  the
75th percentile.

The Chief Executive Officer’s review of the performance of the

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
companies  (when  available)  and 
the  Radford  Global
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 2017, after consulting with
our  independent  compensation  consultant,  the  committee

determined  that  the  following  companies  comprise  the  peer
group for fiscal 2017:

Brocade (BRCD)

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.

Components of Our Executive
Compensation Program
The  principal  components  of  our  executive  officer
compensation  and  employment  arrangements  during  fiscal
2017 included:

• Base salary;

• Annual cash incentive plan;

• Equity awards; and

• Other benefits.

Base Salary
Base salary is the foundation to providing an appropriate total
direct  compensation  package.  We  use  base  salary  to  fairly
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,
seniority,  skills,  knowledge,  performance  and  contribution.
After no increases in fiscal 2016, the committee increased the
base  salaries  of  our  NEOs  in  fiscal  2017,  as  supported  by
compensation analysis provided by Compensia.

compensation  is  in  the  form  of  variable  incentive  cash
compensation  tied  to  committee-established  goals.  In  fiscal
2017, Coherent maintained one incentive cash program under
which executive officers were eligible to receive annual cash
incentives,  the  2017  Variable  Compensation  Plan  (‘‘2017
VCP’’).

2017 VCP
The  2017  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  2017  VCP,  participants  were  eligible  to  receive
bi-annual bonuses (with measurement periods for the first half
and  the  second  half  of  the  2017  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 2017 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

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 2017, 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.

the
Our  performance-based  RSU  grants  are

value  under  current  short  and  long-term  compensation
arrangements for the CEO. In addition, the committee reviews
a  compensation  overview  prepared  by  its  compensation
consultant  reflecting  the  intrinsic  value  of  unvested  equity
awards and performance-based RSUs at target and projected
values for all of the NEOs.

Fiscal 2017 Equity Grants
For fiscal 2017, 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  2017  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 2017 equity grants:

Maximum vest: 200% of target

In  addition  to  our  general  fiscal  2017  equity  grants,  the
committee on November 15, 2016 determined in recognition
of the acquisition and integration of Rofin to grant to certain
integration 
team  members  (including  certain  executive
officers) RSUs with a single vesting date one year from the
date  of  grant.  Messrs. Palatnik,  Sechrist  and  DiMarco
received such Rofin integration RSU grants in the amount of
1,049, 928 and 891 RSUs, respectively.

For our Chief Executive Officer, greater than half of his total
equity awards are performance-based. Accordingly, for our
Chief  Executive  Officer,  at  target,  approximately  65%  of  his
equity  awards  are  performance-based  and  at  maximum

achievement  that  percentage  increases  to  approximately
78%.

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
performance-based shares would, subject to the terms of the
Change  of  Control  Severance  Plan,

anniversary of the grant.

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.

stock  units 

In fiscal 2017 the committee granted an aggregate of 303,390
time-based  and  performance-based
shares  subject 
restricted 
representing
approximately  1.23%  of  Coherent’s  outstanding  common
stock  as  of  September  30,  2017  (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 2017 equity grants were only 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
RSUs) are required to be held until the guidelines are met. As
of December 31, 2017, Mr. Ambroseo held outstanding stock
times  his  base  salary  and,
worth  approximately  39 
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
to
Deferred  Compensation  Plan  permits  participants 
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.

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.

Employee Stock Purchase Plan
Our stockholders have approved an employee stock purchase
plan whereby employees can purchase shares for a discount,
subject to various participation limitations. As employees, our
NEOs are eligible to participate in this plan.

Compensation Discussion and Analysis

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. 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 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
Accounting for Stock-Based Compensation—We account for
the
stock-based  compensation 
requirements  of  ASC  718.  We  also  take  into  consideration
ASC 718 and other generally accepted accounting principles

based compensation programs.

Compensation Discussion and Analysis

certain executive officers unless the compensation is less than
$1  million  during  any  fiscal  year  or  with  respect  to  certain
compensation taxable in fiscal years before fiscal year 2019 or
certain  grants  before  November  3,  2017,  is  ‘‘performance-
based’’  under  Section  162(m).  Certain  performance-based
RSUs granted before November 3, 2017 are intended to be
fully tax-deductible. Cash compensation (including both base
salary  and  payments  under  our  2017  VCP)  and  time-based
full-value  awards  are  not  qualified  as  ‘‘performance-based’’
compensation under Section 162(m). Although the committee
may consider the impact of Section 162(m) as well as other tax
and  accounting  consequences  when  developing  and
the
implementing  executive  compensation  programs, 
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

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

application  and  interpretation  of  Section  162(m), including
with respect to the effective date and transition provisions for
when  certain  ‘‘performance-based’’  compensation  in  excess
of $1 million may no longer be deductible under the recently-
enacted  tax  legislation,  as  well  as  operational  issues,  no
assurances can be given that compensation, even if intended
to  satisfy 
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.

committee continues to monitor the SEC rule-making related
to Section 954 of the Dodd-Frank Act. Following the final rules
being adopted by the SEC, the committee intends to review
and  update  its  clawback  policy.  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 2017, 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.

Failure to meet a minimum level of performance would have resulted in no bonus paid out under the 2017 Variable Compensation Plan.

(2) Reflects the amount earned under the 2017 Variable Compensation Plan during fiscal 2017.

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

conditions) for fiscal 2017 in accordance with ASC 718, and includes grants made in fiscal 2017. 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

2017. 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  $8,163,171,  $1,296,060,  $1,237,137,  $1,178,467  and  $1,083,987,  for  Messrs.  Ambroseo,  Palatnik,  Sobey,  Sechrist  and  DiMarco,

respectively. These amounts do not correspond to the actual value, if any, that will be recognized by the NEOs. See ‘‘Compensation Discussion and Analysis—

(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 $235.17, the closing price of our common stock on September 29, 2017, the last

trading date of fiscal 2017.

(3) 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%.

(4) The performance-based RSU vesting determination date is November 13, 2018. 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 3, 2017. The performance-based RSUs vested at 200% based on the

achievement of certain performance metrics.

Summary Compensation and Equity Tables

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,  2017  (the  last  trading
date of fiscal 2017). 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

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.

(1) Reflects salary as in effect as of September 29, 2017. Bonus severance is based on target bonus as a percentage of salary

as in effect as of September 29, 2017.

(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 29, 2017 (the last trading date
before the end of our fiscal year) at the closing stock price on that date ($235.17). The value of accelerated stock options is

47

Summary Compensation and Equity Tables

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 29, 2017; 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 29, 2017. 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 29, 2017, 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.

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:

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 ten (10) times either in person or by
telephone  and  acted  one  (1)  time  by  unanimous  written
consent during fiscal 2017. 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
the
focused  dialogue  with 
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 2017, 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 2017 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 30, 2017,
for filing with the SEC.

Respectfully submitted by the Audit Committee.

PART I

ITEM 1. BUSINESS

GENERAL

Business  Overview

Our fiscal year ends on the Saturday  closest to September 30. Fiscal years 2017,  2016 and 2015
ended on September 30, October 1, and  October 3, respectively, and  are  referred to in this annual
report as fiscal 2017, fiscal 2016 and fiscal 2015  for convenience. Fiscal  years 2017 and 2016 included
52 weeks and fiscal year 2015 included  53 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.

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 for all
periods presented. 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 operations is the measure of  profit and loss that our  chief operating decision maker

(‘‘CODM’’) uses to assess performance and make  decisions. Income from 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
web site, access to our annual report on  Form  10-K, our quarterly reports  on Form 10-Q, our current
reports on Form 8-K and amendments  to  those reports filed or furnished pursuant  to  Section 13(a) or
15(d) of the Securities Exchange Act of 1934, as  amended (the ‘‘Exchange  Act’’), as soon as  reasonably

5

practicable after we file or furnish them electronically with the  Securities  and Exchange  Commission
(‘‘SEC’’). Information contained on our web site  is not part of this annual  report or our other filings
with the SEC. Any product, product name, process, or technology described in  these  materials  is the
property of Coherent.

RECENT EVENTS

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

dated March  16, 2016. Rofin is 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 hold separate and divest  Rofin’s low power CO2 laser
business based in Hull, United Kingdom (the  ‘‘Hull Business’’)  and have reported this business
separately as  a discontinued operation in  this Form 10-K for the year ending September 30, 2017.  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’’ in the  Notes
to Consolidated Financial Statements.

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.
(‘‘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.

During  fiscal 2017, we made payments on our  Euro  Term Loan of a total  of  156.7 million Euros,

including voluntary payments of a total of  150.0 million Euros.

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.

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

6

used to create ultrafast output—a series of  pulses with pulse durations as short as attoseconds
(10(cid:3)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, tablet
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 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

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

8

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  a  new  generation of flexible
OLED displays which are currently undergoing rapid  growth as  their adoption  into  smart  phones
accelerates.

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

9

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
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.

Lasers have also become a valuable tool in high-brightness (‘‘HB’’) light-emitting diode (‘‘LED’’)

manufacturing, improving LED performance and yield. LEDs have enjoyed widespread adoption as  the
light source in all categories of LCD displays, from phones to full size  TVs and are  also moving  into
general lighting. Our lasers are used in  back-end processing of  HB-LEDs.

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 rails, beam delivery components, laser diagnostic
equipment and complete laser 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.

10

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. We are vertically integrated with  active  fiber manufacturing and are
executing plans to be integrated with world class diodes, which  makes  us very well  positioned  to
succeed in the high power fiber laser  market  in the intermediate  and  long term. 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.  Additive manufacturing or  3D printing is  another
growing market where lasers have seen rapid growth. We serve  this market with 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 lasers as well
as 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 and PRC series of high
power CO2 lasers; high power fiber lasers; the DF series of high power diode laser systems; the
StarFiber mid-power fiber lasers; the NuQ Q-switched fiber lasers; 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,  Tool, Open, 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 include  the  PowerLine  series for
marking; 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.

11

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
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:3)15 to 10(cid:3)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.

12

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  and that we  will see continued increased adoption of our solid-
state, CO2, fiber, direct diode and excimer laser  systems,  as all these lasers enable entirely new
applications, performance improvements and reduced process  costs.

Excimer laser based LTPS is a key technology for producing high  resolution  OLED displays in
general and flexible OLED displays in particular. We believe  we  are  well positioned to take advantage
of the rapid growth that is projected  for OLED  displays in  smart phones  and other mobile  devices over
the next several years with our Vyper and  LineBeam systems.

CO2, Avia, Matrix, Rapid, Monaco, Helios and direct  diode  lasers all seem  aligned with the  need

for related FPD touch panel, film cutting,  light guide  technology, repair  and  frit  welding.

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 seem
likely to be enabled by our lasers, to meet  the increasing demands and decreasing tolerances of these
markets.

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

13

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
laser.

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

metal cutting applications continues.  In addition, we  see additional opportunities in newer applications
such as laser cladding, heat treatment  and  3D  printing.

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

OEM components and instrumentation

The bio instrumentation market is on  a steady path in the most  important areas: microscopy, flow

cytometry and DNA sequencing, which  all are 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. In
aesthetic laser procedures, 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 seems stable overall, 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 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  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.

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
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.

16

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:3)15 seconds) to a few tens of picoseconds  (10(cid:3)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.

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, Finland, 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 83% of our net  sales in fiscal 2017, 76% of our net
sales in fiscal 2016 and 73% of our net  sales in fiscal 2015. Sales made to  independent representatives

17

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 2017, 2016 and 2015.  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.  Warranties on some of our products  and services
may be shorter or longer than one year.  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.

RESEARCH AND DEVELOPMENT

We  are constantly developing and introducing  new products  as well  as improving and  refining
existing products to better serve the  markets we  participate in. Our development efforts  are focused on
designing and developing products, services and solutions that  anticipate  customers’  changing needs and
emerging technological trends. Our efforts are also focused on  identifying the  areas where we believe
we can make valuable contributions.  Research and development expenditures for fiscal 2017 were
$119.2 million, or 6.9% of net sales compared to $81.8  million,  or  9.5% of net  sales for fiscal 2016  and
$81.5 million, or 10.2% of net sales for  fiscal 2015. We work closely with  customers, both  individually
and through our sponsored seminars,  to  develop products  to  meet customer application and
performance needs. In addition, we are  working with  leading research and educational institutions to
develop new photonics based solutions.

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 some of Rofin’s sites
have been integrated onto our Oracle  ERP and  Agile planning platforms, consistent with the  rest  of
Coherent. This integration process will continue into fiscal 2018 and beyond.

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

18

this  is essential to maintaining high quality products  and enable rapid development and  deployment  of
new products and technologies. We provide  customers with 24-hour technical expertise and quality that
is 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 continue to expand 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  established an
International Procurement Office in Singapore  and have  been increasing our sourcing of  materials  from
Asia to reduce material costs on a global  basis. In fiscal 2015, we increased our vertical  integration
capabilities with the asset acquisition of  the Tinsley  Optics  business from L-3 Communications
Corporation.

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  and
optically pumped semiconductor 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, in our products, which  make us susceptible to supply shortages or price  fluctuations
that could adversely affect our business.’’

Our products are manufactured at our sites in  California, Oregon, Arizona, Michigan,

Massachusetts, New Jersey, Connecticut,  New Hampshire and  Florida in the  U.S.; Germany, Scotland,
Finland, Sweden and Switzerland in Europe; and  South Korea, China, Singapore and Malaysia in Asia.
In addition, we also use contract manufacturers for the production of  certain  assemblies  and turnkey
solutions.

Germany; Devens, Massachusetts; and Singapore. Our micro  application products are  manufactured
and tested in Gilching-Munich, Germany; Tampere, Finland; Plymouth, Michigan; Belp, Switzerland;
and Orlando, Florida. Our diode laser  products are manufactured and tested in  Mainz and Freiburg,
Germany; Tucson, Arizona; and Nanjing, China. Coating of our Slab laser electrodes is performed in
Overath, Germany. Our fiber optics and beam delivery systems are manufactured and tested in
Molndal, Sweden, and power supplies are manufactured and tested in Starnberg-Munich, Germany.
The Company’s active and passive fibers  and amplifiers are manufactured  and tested in East Granby,
Connecticut. Optical engines for fiber  lasers,  fiber lasers  modules and wafer material are designed and
manufactured in Tampere, Finland.

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.

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 30, 2017, we held approximately
700 U.S. and foreign patents, which expire  in  calendar  years 2017 through  2035 (depending on the
payment of maintenance fees) and we  have approximately 275 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—‘‘We may not be able to protect our proprietary
technology which could adversely affect  our competitive advantage’’ and ‘‘We may, in the future, be
subject to claims or litigation from third parties, for claims of  infringement of their proprietary rights or

20

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 Novanta Inc.,  IPG Photonics
Corporation, Lumentum Holdings Inc., MKS Instruments, 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 2017 year-end, our backlog of orders scheduled for  shipment (within one year) was
$1,040.0 million compared to $605.3 million  at fiscal 2016 year-end. By segment, backlog for  OLS was
$801.4 million and $558.6 million, respectively,  at fiscal 2017 and 2016  year-ends.  Backlog for  ILS was
$238.6 million and $46.7 million, respectively,  at fiscal 2017 and 2016 year-ends. The increase in  OLS
backlog from fiscal 2016 to fiscal 2017 year-end is  primarily  due to the timing of large excimer laser
annealing system orders, net of shipments,  for the  flat panel display market. The  increase in ILS
backlog from fiscal 2016 to fiscal 2017 year-end is  primarily  due to the acquisition of Rofin in the  first
quarter of fiscal 2017 and is primarily  concentrated  on orders in the materials processing and high
power fiber laser markets. Orders used to compute  backlog are generally  cancelable  and, depending on
the notice period,  are subject to rescheduling by our customers  with penalties. Historically, we  have not
experienced a significant rate of cancellation or rescheduling, though  we cannot  guarantee that the  rate
of cancellations or rescheduling will not  increase in the  future.

SEASONALITY

We  have historically 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. With the acquisition of Rofin in fiscal 2017,  we expect a more pronounced
decrease in revenues in the first quarter of the  fiscal  year  as Rofin has historically experienced more
pronounced seasonality, particularly in materials processing applications, than Coherent historically  has
experienced. This historical pattern should not be considered a reliable indicator of  the Company’s
future net sales or financial performance.

EMPLOYEES

As of fiscal 2017 year-end, we had 5,218 employees.  Approximately  666 of our employees  are

involved in research and development;  3,382  of  our  employees are  involved in  operations,
manufacturing, service and quality assurance; and 1,170 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.

21

ACQUISITIONS

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. See ‘‘Recent Developments’’ for further discussion  of the
acquisition and the Credit Agreement.

In July 2015, we acquired certain assets  of Raydiance, Inc. (‘‘Raydiance’’) for approximately

$5.0 million, excluding transaction costs.  Raydiance manufactured complete tools and lasers  for
ultrafast processing systems and subsystems  in the precision micromachining processing  market.  The
Raydiance assets have been included  in our OEM Laser Sources  segment.

In July 2015, we acquired the assets and certain liabilities of the  Tinsley Optics  (‘‘Tinsley’’)
business from L-3 Communications Corporation for approximately $4.3 million, excluding transaction
costs. Tinsley is a specialized manufacturer  of high precision optical  components and  subsystems sold
primarily in the aerospace and defense industry. Tinsley manufactures the large form  factor optics for
our  excimer laser annealing systems. The  Tinsley  assets have been included in our  OEM Laser Sources
segment.

Please refer to ‘‘Note 3. Business Combinations’’ 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.  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 current year severance related costs 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 exit from certain  product lines as well as the  consolidation of sales and
distribution offices. The current year  asset write-offs  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. We plan to continue additional restructuring  activities in
fiscal 2018 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.

22

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  Hazardous
Substances Directive (RoHS) went into  effect in  2006, and  was subsequently  revised in 2011  and again
in 2015 (as RoHS 2). Another material  revision  will be in effect in  2019. The Registration, Evaluation,
Authorization and Restriction of Chemicals (REACH) went into effect  in 2007, and is  amended 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,  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.

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

Certain of our lasers sold in the United States are  classified  as Class  IV Laser Products 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 device, make periodic

23

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
applicable laws and regulations relating  to  the manufacture of laser  devices.

SEGMENT INFORMATION

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 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: OEM Laser Sources  (‘‘OLS’’)  and
Industrial Lasers & Systems (‘‘ILS’’).  Accordingly,  our  segment information was restated retroactively
for all periods presented. 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
Industrial Lasers & Systems segment.

We  have identified OLS and ILS as operating segments  for which discrete financial information
was 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.

FINANCIAL INFORMATION ABOUT  FOREIGN AND DOMESTIC OPERATIONS AND  EXPORT

SALES

Financial information relating to foreign and domestic operations  for fiscal years 2017, 2016  and

2015, is set forth in Note 15, ‘‘Segment  and Geographic  Information’’ of our Notes to Consolidated
Financial Statements under Item 15 of  this annual report.

24

ITEM 1A. RISK FACTORS

You should carefully consider the followings  risks when considering  an investment in our  common
stock. These risks could materially affect  our business, results of operations or financial condition,  cause the
trading price of our common stock to decline materially or cause  our actual results to  differ  materially from
those expected or those expressed in any  forward-looking  statements made by  us.  These  risks are not
exclusive, and additional risks to which we are subject include,  but  are not limited to, the factors mentioned
under ‘‘Forward-Looking Statements’’  and  the 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.

RISKS RELATED TO THE MERGER WITH ROFIN

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:

(cid:127) 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;

(cid:127) 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;

(cid:127) diversion of the attention of our management;  and

(cid:127) the disruption of, or the loss of momentum in, our business or inconsistencies in  standards,
controls, procedures or policies, any of which  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.

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 will pose substantial challenges for management, including challenges  related to the
management and monitoring of new operations and associated increased costs and  complexity. There
can be no assurances that we will be  successful  or that we will realize the  expected synergies and
benefits anticipated from the merger.

25

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, which  will result in charges to earnings that could
have a material adverse effect on the  market  value of our  common  stock following  completion  of the
acquisition. 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 are 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  30, 2017, 513.3 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 following completion 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 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

26

capital expenditures, dividends, share  repurchases and other activities and  may create  competitive
disadvantages for us relative to other  companies with lower  debt levels.

BUSINESS ENVIRONMENT AND INDUSTRY  TRENDS

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:

(cid:127) general economic uncertainties in the  macroeconomic and local economies facing us,  our

customers and the markets we serve;

(cid:127) fluctuations in demand for our products or downturns in  the industries that we  serve;

(cid:127) our reliance on contract manufacturing;

(cid:127) our reliance in part upon the ability of our OEM  customers to develop and sell systems  that

incorporate our laser products;

27

(cid:127) our customers’ ability to manage their  susceptibility to adverse  economic conditions;

(cid:127) the rate of market acceptance of our new products;

(cid:127) the ability of our customers to pay  for our products;

(cid:127) expenses associated with acquisition-related activities;

(cid:127) 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;

(cid:127) jurisdictional capital and currency controls negatively  impacting our  ability  to  move  funds from

or to an applicable jurisdiction;

(cid:127) access  to applicable credit markets by  us, our  customers and their end  customers;

(cid:127) delays or reductions in customer purchases of our  products  in anticipation of the introduction of

new and enhanced products by us or our competitors;

(cid:127) our ability to control expenses;

(cid:127) the level of capital spending of our  customers;

(cid:127) potential excess and/or obsolescence of our  inventory;

(cid:127) costs and timing of adhering to current and developing governmental regulations and reviews

relating to our products and business;

(cid:127) costs related to acquisitions of technology or businesses;

(cid:127) impairment of goodwill, intangible  assets and other  long-lived assets;

(cid:127) our ability to meet our expectations and forecasts and those of public market analysts  and

investors;

(cid:127) the availability of research funding by  governments with regard  to  our customers in the scientific

business, such as universities;

(cid:127) continued government spending on  defense-related and scientific research  projects  where we are

a subcontractor;

prefer not to accept;

(cid:127) changes in policy, interpretations, or challenges to the allowability of costs  incurred under

government cost accounting standards;

(cid:127) damage to our reputation as a result of coverage in  social  media, Internet  blogs or  other  media

outlets;

(cid:127) managing our and other parties’ compliance with contracts in multiple  languages and

jurisdictions;

compliance with all applicable laws;

(cid:127) impact of government economic policies on macroeconomic conditions;

(cid:127) costs and expenses from litigation;

(cid:127) costs associated with designing around or payment  of licensing fees associated  with issued

patents in our fields of business;

28

(cid:127) government support of alternative energy industries,  such as solar;

(cid:127) 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;

(cid:127) 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;

(cid:127) negative impacts related to government instability, including  the recent difficulties  in forming a

governing coalition in Germany;

(cid:127) the future impact of legislation, rulemaking, and changes  in accounting, tax, defense

procurement, or export policies; and

(cid:127) 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,  both internal  and external, 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, both internal  and external. 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

29

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-cancelable purchase orders or
otherwise assume liability for a large amount  of the ordered supplies, which limits our ability to adjust
down our inventory liability in the event of market downturns or other customer cancellations or
rescheduling of their purchase orders  for our products.

Some of  our products, particularly in the  flat panel display industry,  require designs and
specifications that are at the cutting-edge of available technologies and change  frequently  to  meet
rapidly evolving market demands. By their  very nature, the types of components  used  in such  products
can be difficult and unpredictable to  manufacture  and  may  only be available  from a single supplier,
which  increases the risk that we may not obtain such  components in a  timely manner. Identifying
alternative sources of supply for certain components could be difficult and costly, result  in management
distraction in assisting our current and future suppliers to meet our and our customers’ technical
requirements, and cause delays in shipments of  our  products while  we  identify, evaluate  and test the
products of alternative suppliers. Any  such delay in shipment would  result in  a delay or  cancelation  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.  We
have historically relied exclusively on  our  own production capability  to  manufacture certain strategic
components, crystals, semiconductor lasers, fiber, lasers and  laser-based systems.  In  July 2015,  we also
began manufacturing 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.

30

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 2017, 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. 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 canceled  orders  by our customers. This could
negatively impact our backlog, timing of  net sales and results of operations.

As of September 30, 2017, flat panel  display systems  represented 59% of  our backlog, compared to

63% at October 1, 2016. Since our backlog includes  higher average selling price flat panel display
systems, any delays or cancellation of shipments could have a material  adverse effect on  our  financial
results.

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 (ELA) 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:

(cid:127) loss of customers or orders;

(cid:127) increased costs of product returns  and warranty expenses;

(cid:127) damage to our brand reputation;

(cid:127) failure to attract new customers or achieve market acceptance;

(cid:127) diversion of development, engineering  and  manufacturing  resources; and

(cid:127) legal actions by our customers and/or their end users.

31

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.

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 canceled, 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.

32

The financial turmoil that has affected  the banking system and financial markets in  recent years

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

33

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

34

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 2017, fiscal 2016 and fiscal  2015, 83%, 76%  and 73%, 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
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:

(cid:127) longer accounts receivable collection periods;

(cid:127) the impact of recessions and other  economic conditions in economies outside the United  States;

(cid:127) unexpected changes in regulatory requirements;

(cid:127) certification requirements;

(cid:127) environmental regulations;

(cid:127) reduced protection for intellectual property rights  in some  countries;

(cid:127) potentially adverse tax consequences;

(cid:127) political and economic instability;

(cid:127) import/export regulations, tariffs and trade  barriers;

(cid:127) compliance with applicable United States and foreign anti-corruption  laws;

(cid:127) less than favorable contract terms;

(cid:127) reduced ability to enforce contractual obligations;

(cid:127) cultural and management differences;

(cid:127) reliance in some jurisdictions on third party sales channel partners;

(cid:127) preference for locally produced products;  and

(cid:127) 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 able to protect our proprietary technology, our competitive advantage could be  harmed.

Maintenance of intellectual property rights and the protection thereof is important  to  our business.

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

We 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 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:

(cid:127) stop manufacturing, selling or using our products  that use the  infringed intellectual property;

(cid:127) 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

(cid:127) 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.

36

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.

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 Novanta Inc.,  IPG
Photonics Corporation, Lumentum Holdings Inc., MKS Instruments, 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

37

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
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.

38

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.

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  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:

(cid:127) issue stock that would dilute our current  stockholders’ percentage  ownership;

(cid:127) pay cash that would decrease our working capital;

(cid:127) incur debt;

(cid:127) assume liabilities; or

(cid:127) incur expenses related to impairment of goodwill and amortization.

Acquisitions also involve numerous risks, including:

(cid:127) problems combining the acquired operations, systems, technologies or products;

(cid:127) an inability to realize expected operating efficiencies or product integration benefits;

(cid:127) difficulties in coordinating and integrating  geographically separated  personnel, organizations,

systems and facilities;

(cid:127) difficulties integrating business cultures;

(cid:127) unanticipated costs or liabilities, including the costs  associated  with improving the internal

controls of the acquired company;

(cid:127) diversion of management’s attention  from our core businesses;

(cid:127) adverse effects on existing business  relationships  with suppliers  and customers;

(cid:127) potential loss of key employees, particularly  those of  the purchased organizations;

(cid:127) incurring unforeseen obligations or liabilities in  connection with acquisitions; and

(cid:127) 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.

39

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:

(cid:127) maintaining and enhancing our relationships with our customers;

(cid:127) the education of potential end-user  customers about  the benefits of lasers and laser systems; and

(cid:127) our ability to accurately predict and develop our products to meet industry standards.

For our fiscal years 2017, 2016 and 2015,  our research and development costs  were $119.2  million

(6.9% of net sales), $81.8 million (9.5% of net sales) and $81.5 million (10.2% of net sales),
respectively. 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. 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.

40

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

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

From time to time new regulations are  enacted, and it is difficult to anticipate  how such

regulations will be implemented and  enforced.  We continue  to  evaluate the  necessary  steps  for
compliance with regulations as they are enacted.  These regulations include, for example, the
Registration, Evaluation, Authorization  and Restriction of Chemical  substances (‘‘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

41

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
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:

(cid:127) 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;

(cid:127) change in the assessment of the ability  to  recognize our deferred  tax assets and change in the

valuation of our deferred tax liabilities;

42

(cid:127) the outcome of discussions with various tax authorities regarding  intercompany  transfer  pricing

arrangements;

(cid:127) 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;

(cid:127) changes in the composition of earnings in countries or states with  differing  tax rates;

(cid:127) the resolution of issues arising from tax audits with  various tax authorities, and in particular,  the

outcome of the German tax audits of our tax returns for fiscal years 2010  - 2015;

(cid:127) adjustments to estimated taxes upon finalization of various tax returns;

(cid:127) increases in expenses not deductible for tax purposes, including impairments of goodwill in

connection with acquisitions;

(cid:127) our ability to meet the eligibility requirements  for tax holidays  of limited time  tax-advantage

status;

(cid:127) changes in available tax credits;

(cid:127) changes in share-based compensation;

(cid:127) changes in the 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’’);

(cid:127) changes in generally accepted accounting principles; and

(cid:127) the repatriation of non-U.S. earnings for which we have  not  previously  provided for U.S.  taxes.

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, including various  announcements from the  United
States government potentially impacting our  ability to defer taxes on international earnings.  For
example, the ‘‘Tax Cuts and Jobs Act’’  proposed by U.S. federal tax legislation would have a significant
impact on the taxation of Coherent including the U.S. tax treatment  of our  foreign operations.  We are
reviewing the potential changes to the  tax laws and  will  revise  our tax estimates to the extent the
legislation is enacted.

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

43

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

Governmental regulations, including duties, affecting the import or  export of products could  negatively affect
our net sales.

The United States and many 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 approval for our products, could  harm  our  international and  domestic  sales  and adversely  affect
our  net sales. From time to time our duty  calculations and  payments are audited by government
agencies. For example, we were audited in South Korea for customs  duties and value-added-tax for the
period 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 assessments  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. 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.

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

44

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 may discourage, delay  or prevent a  merger

or acquisition 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:

(cid:127) the ability of our board of directors to alter  our bylaws without stockholder approval;

(cid:127) limiting the ability of stockholders  to call  special meetings; and

(cid:127) 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 currently plan to renew leases on buildings as  they  expire, as  necessary.

We  maintain other sales and service  offices  under varying leases expiring from 2018 through  2022

in Japan, China, Taiwan, South Korea, France, Italy, Germany, Belgium, Spain, the United Kingdom
and the Netherlands.

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

46

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 alleges  that  the
use of certain of the Company’s lasers infringes 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 seeks unspecified compensatory  damages, the cost of court proceedings and seeks 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 has appealed this decision to the  Federal  Court  of  Justice, the highest civil jurisdiction court in
Germany. The infringement action is  currently stayed pending the outcome of such  appeal.
Management has made an accrual with respect to this  matter and has determined, based on its current
knowledge, that the amount or range  of reasonably possible  losses  in excess of the amounts  already
accrued is not reasonably estimable.  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 duty calculations and payments are audited
by government agencies. During the  second quarter of fiscal 2016, we concluded an  audit in South
Korea for customs duties and value added  tax  for the  period March 2009 to March 2014. We paid
$1.6 million related to this matter in the second quarter  of fiscal  2016 and  have no remaining accrual at
October 1, 2016.

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. For U.S. federal income tax purposes, all  years  prior to fiscal 2011 are
closed. In September 2017, the Internal  Revenue Service (IRS) completed  its audit of Coherent Inc.’s
fiscal 2013 tax return with no adjustment.  The extension of the statutes of limitations for its fiscal 2011
and 2012 tax returns will be closed on June  30,  2018. In our major  foreign jurisdictions and our  major
state jurisdictions, the years prior to fiscal  2011 and 2013,  respectively, are closed to examination.
Earlier years in our various jurisdictions  may remain open  for adjustment  to  the extent that we have
tax attribute carryforwards from those years.

In July 2015 and March 2016, Coherent Kaiserslautern  GmbH (formerly Lumera Laser GmbH)

received tax audit notices for the fiscal  years  2010 to 2014. The audit began in August 2015. We
acquired the shares of Lumera Laser  GmbH in December  2012 and, pursuant to the terms of the
acquisition agreement, we should not have responsibility for any assessments related to the
pre-acquisition period. In July 2016, Coherent Holding  GmbH and Coherent Deutschland GmbH  each
received a tax audit notice for the fiscal  years  2011 to 2014. The audit began in August 2016. In
November 2016, Coherent GmbH, Coherent  LaserSystems GmbH &  Co. KG and Coherent
Germany GmbH received audit notices  for the  period that they were in existence during the fiscal years
2011 through 2014. The audit work began in January 2017. In  the fourth quarter of fiscal 2017, all
German tax audits were extended to fiscal  2015 and  are currently in progress.

We  regularly engage in discussions and negotiations with tax authorities regarding tax matters in

various jurisdictions and management  believes  that it  has adequately  provided reserves for any
adjustments that may result from tax  examinations.

The number of stockholders of record as  of November 24, 2017 was  667. 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 2017.

There were no stock repurchases during the fourth quarter of fiscal  2017.

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 supersedes 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  and  2013 were immaterial.

(1) 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

$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.

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
measures and should not be considered as an alternative to any other  measure for  determining
operating performance that is calculated  in accordance with generally accepted accounting principles.
As previously announced, management  determined that we would  no longer present non-GAAP
bookings data effective in the second quarter  of fiscal 2017. We were one of the few companies in the
industry that provided bookings information, which we believe put  us at a competitive disadvantage.  In
addition, our  bookings volatility has and will continue to be high by virtue of the  excimer  laser
annealing (‘‘ELA’’) business where high average selling prices  can  cause large  swings in bookings;  these
swings  are not indicative of the long-term potential of the  business. We believe this change will put
more focus on our key performance metrics discussed below. Accordingly, we  no longer provide
bookings, book-to-bill ratio and related disclosure  in our MD&A.

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
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 since the  acquisition  on
November 7, 2016. Net sales for fiscal  2016  increased 10.2% in our OLS segment and decreased 8.0%

52

in our ILS segment from fiscal 2015.  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 increased  to  53.6% in
fiscal 2017 from 48.3% in fiscal 2016 and from 45.5% in  fiscal  2015. Gross profit percentage for ILS
decreased to 24.4% in fiscal 2017 from  26.0% in fiscal 2016  and from 27.0% in fiscal 2015.  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 decreased  to  6.9% in fiscal  2017 from 9.5% in
fiscal 2016 and 10.2% in fiscal 2015.  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 are 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 2017 decreased to 63.9 days from 69.6 days  in fiscal 2016. The  decrease in DSO  in receivables is
primarily due to higher sales of ELA tools used in the flat  panel  display market in Asia and  the timing
of collection of those receivables, lower sales  and  receivables in Japan  which typically has a higher  DSO
and a lower concentration of sales in  the last two months of  the year partially  offset by the  impact  of
our  acquisition of Rofin, which has higher DSOs than  those previously reported by us prior to the
acquisition.

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.  The  more money we  have tied  up in
inventory, the less money we have available for research and development,  acquisitions,  expansion,

53

marketing and other activities to grow our business. Our annualized fourth quarter inventory turns for
fiscal 2017 increased to 2.6 turns from  2.5 turns  in fiscal 2016. Improvements  in turns due to higher
shipments of large ELA tools used in  the flat panel display market were partially  offset by the impact
of our acquisition of Rofin in the first quarter  of fiscal 2017 due to Rofin’s lower  inventory  turns rate.

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 decreased to 3.7%  in fiscal
2017 from 5.8% in fiscal 2016. Our capital  spending  percentage  increased to 5.8%  in fiscal 2016
from 2.8% in fiscal 2015. 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. The fiscal 2016 increase was primarily due to increased investments to
expand our manufacturing capacity in G¨ottingen, Germany, the upgrade of certain of our production
facilities in California and New Jersey  and higher  purchases of production-related assets,  partially  offset
by the impact of higher revenues in fiscal 2016.

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 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.

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 and related financing

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

dated March  16, 2016. Rofin is 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 hold separate and divest  Rofin’s low power CO2 laser
business based in Hull, United Kingdom (the  ‘‘Hull Business’’)  and have reported this business
separately as  a discontinued operation in  this Form 10-K for the year ending September 30, 2017.  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’’ 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 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.
(‘‘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.

55

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

On July 24, 2015, we acquired certain assets  of Raydiance, Inc.  (‘‘Raydiance’’)  for approximately

$5.0 million, excluding transaction costs.  Raydiance manufactured complete tools and lasers  for
ultrafast processing systems and subsystems  in the precision micromachining processing  market.  The
Raydiance assets have been included  in our OLS segment.

On July 27, 2015, we acquired the assets  and  certain liabilities of the Tinsley Optics (‘‘Tinsley’’)

business from L-3 Communications Corporation for approximately $4.3 million, excluding transaction
costs. Tinsley is a specialized manufacturer  of high precision optical  components and  subsystems sold
primarily in the aerospace and defense industry. Tinsley manufactures the large form  factor optics for
our  excimer laser annealing systems. The  Tinsley  assets have been included in our  OLS segment.

On June 8, 2010, we invested $2.0 million  in SiOnyx, Inc.,  a privately-held company. The

investment was included in other assets and was being carried on a cost basis. During  the third quarter
of fiscal 2015 we determined that our investment  became other-than temporarily impaired. As  a result,
we recorded a non-cash charge of $2.0  million to operating  expense in  our results of operations in the
third quarter of fiscal 2015.

RESULTS OF OPERATIONS—FISCAL 2017, 2016  AND 2015

Fiscal 2017 and 2016 consisted of 52  weeks. Fiscal 2015 consisted of  53 weeks.

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  cancelable and, depending on the
notice period, are subject to rescheduling  by our  customers without substantial penalties. Historically,
we have not experienced a significant  rate of cancellation or rescheduling, though we cannot  guarantee
that the rate of cancellations or rescheduling will  not increase in  the future.  We had a backlog  of
orders shippable within 12 months of  $1,040.0 million at September 30,  2017, including a significant
concentration in the flat panel display  market  (59%) for customers which  are primarily located in Asia.

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. 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.

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. We expect
continued growth in the microelectronics market with  flat panel display demand  fully utilizing our
manufacturing capacity in fiscal 2018,  higher flat panel  display revenues from consumable parts due to
our  higher installed base, spending in the  semiconductor capital equipment market at a level similar to
fiscal 2017 and continued recovery in  the advanced  packaging market. 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. We
expect continued growth in multiple  materials processing  applications including  automotive (especially
battery welding for electric vehicles)  and  machine  tooling, medical device manufacturing, consumer
goods manufacturing for packaging, converting,  marking and additive manufacturing. We also  expect
continued steady progress in sales of our high power fiber lasers and  are  expanding  our  manufacturing
capacity  accordingly. 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. In OEM components and instrumentation applications, we are seeing  strong
demand in the bio-instrumentation market, higher demand for  consumables in the  medical  market,  in
dental applications and in eye disease management  as well as  increased demand in the  defense  and
aerospace market. 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.  We expect demand in  the scientific  and
government programs market to continue to fluctuate  from  quarter to quarter.

During  fiscal 2016, net sales increased by $54.9 million, or 7%, compared to fiscal  2015, including

decreases due to the unfavorable impact  of foreign exchange rates, with  sales  increases in the
microelectronics, materials processing  and  scientific and government  programs  markets  partially offset

58

by decreases in the OEM components and instrumentation market. Microelectronics sales increased
$48.7 million, or 12%, primarily due to higher shipments for flat panel display annealing  systems and
higher  shipments for semiconductor applications  partially offset by lower  shipments for advanced
packaging applications. Materials processing sales  increased  $13.0 million, or 12%,  during  fiscal 2016
primarily due to higher shipments for cutting,  marking  and other materials processing applications. The
increase in scientific and government  programs market sales of $0.3 million, or 0%, during  fiscal  2016
was primarily due to higher demand for  advanced research applications used by university and
government research groups. The decrease  in the OEM  components  and  instrumentation  market of
$7.2 million, or 4%, during fiscal 2016  was primarily due to lower  shipments for medical and  machine
vision  applications  partially offset by  higher shipments for military  and bio-instrumentation applications.

The timing for shipments of our higher average selling price  excimer  products in the flat panel

display  market have historically fluctuated and are in  the future  expected to fluctuate  from
quarter-to-quarter due to customer scheduling,  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 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. With the acquisition of Rofin in fiscal 2017,  we expect a more pronounced
decrease in revenues in the first quarter of the  fiscal  year  as Rofin has historically experienced more
pronounced seasonality, particularly in materials processing applications, than Coherent historically  has
experienced.

In fiscal  2017, 2016 and 2015, one customer accounted  for 23%, 13% and 17% 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.

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.
Net sales for  fiscal 2016 increased $54.9 million, or 7%, compared  to  fiscal  2015, with increases of
$66.7 million, or 10.2%, in our OLS  segment and  decreases of  $11.7 million,  or 8.0%, in  our ILS
segment. Both the fiscal 2016 increase  and decrease in OLS and  ILS segment sales, respectively,
included decreases due to the unfavorable impact of  foreign exchange rates.

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 OLS
segment sales in fiscal 2016 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 materials
processing, semiconductor and military  applications partially offset  by lower shipments  for medical and
advanced packaging applications. The fiscal 2016  increase includes an increase of $11.3  million,
primarily in military and scientific applications, resulting from our acquisitions  of  Tinsley and
Raydiance assets in the fourth quarter  of fiscal  2015.

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.  The  decrease in our  ILS  segment sales from fiscal
2015 to fiscal 2016 was primarily due  to  lower advanced packaging, materials  processing and medical
application sales.

Gross Profit

Consolidated

Our gross profit rate 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 rate increased by 2.7%  to  44.5% in fiscal  2016 from 41.8% in fiscal 2015 primarily

due to favorable product margins (2.2%)  resulting  from the impact of higher volumes  in certain
business units (primarily flat panel display  applications) and  the favorable impact from foreign currency
fluctuations (primarily the Euro and Yen) as well as favorable mix  in the microelectronics market,
particularly for flat panel display applications,  net of unfavorable mix  in the OEM  components and
instrumentation market. In addition, the  margin also  benefited from  lower other costs  (0.3%) due
primarily to an accrual in the third quarter of fiscal 2015  for a customs audit in South  Korea and lower
inventory charges for excess or obsolete inventory  as well  as  lower  warranty  costs (0.2%) due to fewer
warranty events.

Our gross profit rate 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

60

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 rate 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 rate 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%).

Our OLS gross profit rate increased  by 2.8% to 48.3%  in fiscal 2016 from 45.5% in  fiscal  2015
primarily due to favorable product margins (2.4%), lower warranty costs (0.2%) due to fewer warranty
events, lower other costs (0.1%) and  lower intangibles  amortization expense (0.1%). The 2.7%  product
margin improvement resulted from the  impact  of higher  volumes in  most business units  and the
favorable impact from foreign currency fluctuations (primarily the Euro and Yen) as  well as favorable
mix in the microelectronics market, particularly for flat panel display  applications, including  favorable
service mix net of  unfavorable mix in the  OEM  components  and instrumentation  market.

Industrial Lasers & Systems

Our ILS gross profit rate 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 is  primarily  related to the exit  from our preexisting
high power fiber laser product line and other Rofin product  lines. The decreases in  gross profit rate
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.

Our ILS gross profit rate decreased by 1.0% to 26.0% in fiscal 2016  from 27.0%  in fiscal 2015
primarily due to unfavorable product margin (1.1%)  and higher  warranty  costs  (0.3%) due to more
warranty events partially offset by lower  other  costs (0.5%)  due to lower freight  and packaging costs  as
well as lower inventory charges for excess or obsolete  inventory. The 1.1% product margin
deterioration resulted from unfavorable  yields and lower volumes in certain business units partially
offset by favorable mix in the OEM  components and instrumentation and materials processing markets.

Research and development

Fiscal 2017 research and development (‘‘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 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 historical 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 research
and development spending increased $7.4 million  primarily  due to higher net spending on projects. ILS
spending increased $27.7 million primarily  due to our acquisition of Rofin and restructuring costs,
partially offset by lower project spending. Corporate and other 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.

Fiscal 2016 R&D expenses increased $0.3 million, or less than 1%,  from  fiscal 2015, but  decreased

to 9.5% from 10.2% of net sales. The  $0.3  million increase  was primarily due to $2.0 million
incremental spending from the asset acquisitions from Tinsley and  Raydiance, both  of  which were
acquired in the fourth quarter of fiscal 2015, $0.3 million higher stock-based compensation expense  and
$0.3 million higher charges for increases in deferred compensation plan  liabilities.  The increases were
partially offset by $2.3 million lower project  spending  including the  favorable impact of  foreign
exchange rates, lower spending on labor  and  materials  and higher customer reimbursements. On  a
segment basis, OLS spending increased  $0.7 million primarily due to the asset acquisitions from Tinsley
and Raydiance partially offset by lower project spending including the favorable impact of foreign
exchange rates. ILS spending decreased $1.4  million  primarily due  to  lower spending on projects and
higher  customer reimbursements. Corporate and other spending increased $1.0  million primarily due to
higher  charges for increases in deferred compensation  plan liabilities and higher stock-based
compensation expense.

62

Selling, general and administrative

Fiscal 2017 selling, general and administrative  (‘‘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 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
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 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.

Fiscal 2016 SG&A expenses increased $19.3 million, or  13%, from fiscal 2015.  The increase was

primarily due to a net $8.5 million higher  consulting and legal costs related  to  acquisitions in fiscal
2016 compared to fiscal 2015 (of which  $9.8 million was related  to  the acquisition of Rofin in  fiscal
2016) and $6.2 million higher payroll spending primarily due  to  higher variable compensation and
higher  sales commissions net of the favorable impact of foreign  exchange  rates. In addition, the
increase includes $1.8 million higher charges for increases  in deferred compensation  plan liabilities,
$1.6 million higher stock-based compensation expense due to (1)  a higher  average stock price during
fiscal 2016, (2) a higher number of restricted stock shares outstanding and (3) the expense related to
accounting for the  transition agreement  of  our  former CFO, and $1.2  million higher  other net variable
spending including incremental spending  from  the asset acquisitions of Tinsley and  Raydiance. On a
segment basis as compared to the prior  year period,  OLS  segment expenses  increased $4.9 million
primarily due to higher payroll spending and the impact due to the asset  acquisitions from  Tinsley and
Raydiance net of the favorable impact  of  foreign exchange rates.  ILS spending increased $1.0 million
primarily due to higher payroll spending net of the  favorable  impact of foreign exchange  rates.
Spending for Corporate and other increased  $13.4 million primarily due to higher consulting and legal
costs related to acquisitions, higher charges for  increases in deferred compensation plan liabilities,
higher  stock-based compensation expense 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.

On July 27, 2015, we acquired the assets  and  certain liabilities of the Tinsley business from  L-3
Communications Corporation for approximately $4.3 million, excluding transaction  costs (See Note 3).
The purchase price was lower than the fair value of net  assets purchased,  resulting in a  gain of
$1.3 million recorded in our consolidated statements  of  operations for our fiscal year 2015.

63

Impairment of assets held for sale

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.

Impairment of investment

On June 8, 2010, we invested $2.0 million  in SiOnyx, Inc.,  a privately-held company. The

investment was included in other assets and was being carried on a cost basis. During  the third quarter
of fiscal 2015 we determined that our investment  became other-than temporarily impaired. As  a result,
we recorded a non-cash impairment charge of $2.0 million to operating expense in our  results of
operations in the third quarter of fiscal 2015.

Amortization of intangible assets

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.

Amortization of intangible assets increased $0.2 million, or  6%,  from fiscal 2015  to  fiscal  2016
primarily due to increases due to the write-off of IPR&D of $0.4  million  related to our acquisition of
Innolight and due to the asset acquisition from  Raydiance in  the fourth quarter of fiscal 2015 partially
offset by the completion of amortization  of certain  intangibles  from prior  acquisitions.

Other income (expense), net

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.

Other income (expense), net, changed by $3.5  million  to  other expense of $4.7 million  in fiscal

2016 from other expense of $1.2 million  in fiscal 2015.  The  higher expenses were  primarily  due  to
higher  net foreign exchange losses ($4.9  million) and $1.3  million  higher interest expense  primarily  for
the commitment of our term loan to  finance  the acquisition of Rofin partially offset by $2.1 million
higher  gains, net of expenses, on our deferred compensation plan assets and $0.5 million higher  interest
income due to higher balances of cash and short-term investments. The higher  foreign exchange  losses
were primarily due to (1) higher unhedged  exposure in  fiscal 2016, (2)  a loss of $2.2 million on our
hedge of our foreign exchange risk related to the  commitment of our term loan to finance the
acquisition of Rofin, (3) the significant movement of rates in June 2016  due  to  the Brexit  vote  and
(4) higher forward points on our hedging  contracts.

Income taxes

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

64

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).

The effective tax rate on income from continuing operations  before  income taxes for fiscal 2015 of
23.3% 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 South Korea
and Singapore tax exemptions, 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
2014. 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).

During  fiscal 2017, we increased our valuation  allowance  on deferred  tax  assets by $11.1  million to
$28.7 million primarily due to the increase  in California and  other states research and  development tax
credits and the release of R&D tax reserves  for California and other states, which  are not expected to
be recognized. During fiscal 2016, we  increased our valuation allowance on deferred  tax assets by
$2.1 million to $17.6 million primarily due to the increase in California and other states research and
development tax credits which are not expected to be recognized. In making the  determination to
record the valuation allowance, management considered the likelihood of future taxable  income  and
feasible and prudent tax planning strategies to realize  deferred tax assets. In the  future, if we  determine
that we expect to realize deferred tax  assets, an  adjustment to the valuation allowance will  affect
income in the period such determination  is made.

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 $1.1  million and
$0.7 million in fiscal 2017 and fiscal 2016, respectively. There are no tax benefits  for fiscal 2015 due to
the utilization of net operating loss.

FINANCIAL CONDITION

Liquidity and capital resources

At September 30, 2017, we had assets  classified as cash and  cash  equivalents and short-term
investments, in an aggregate amount  of  $475.6  million, compared  to  $400.0 million at October 1, 2016.
Our cash  and cash equivalents and short-term  investments included $151.6 million of cash at  Rofin
entities. In addition, at September 30,  2017, we had $14.0 million of  restricted cash.  At September 30,
2017, approximately $300.0 million of  our  cash and  securities was held in certain of our foreign
subsidiaries, $263.2 million of which was denominated in  currencies other than  the U.S.  dollar. At
September 30, 2017, we had approximately $299.4 million of  cash held  by foreign  subsidiaries  where we

65

intend to permanently reinvest our accumulated earnings  in these entities and our  current plans do not
demonstrate a need for 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 U.S. income taxes and foreign  withholding taxes. An  exception  to  U.S. taxation  may be the
repatriation of foreign funds that had  been previously taxed  in the  U.S. as  Subpart  F income. The
amount of the U.S. and foreign taxes due would  depend  on the amount and manner of repatriation, as
well as the location from where the funds  are repatriated. We actively  monitor the third-party
depository institutions that hold these assets,  primarily focusing  on the  safety of principal and
secondarily maximizing yield on these  assets. We  diversify our cash and  cash  equivalents and
investments among various financial institutions, money market funds, 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.  In  the first  quarter of fiscal 2017,  we spent a
significant portion of our foreign funds  on the Rofin  acquisition.  We did not repatriate foreign funds to
our  domestic operations to fund this acquisition. We  expect to have  adequate foreign  funds  in the
future to service the acquisition debt  and  do not anticipate  any repatriation of foreign funds  to  operate
our  domestic business.

In fiscal  2016, 2015 and 2014, we converted a  total of $160.6 million of cash and securities  held in

certain of our foreign subsidiaries to  U.S.  dollars  and invested those funds within a  European
subsidiary whose functional currency is the  U.S. dollar.  In  the first  quarter of fiscal 2017,  we used these
funds  to purchase Rofin and pay related  acquisition  expenses. The converted funds  were not
repatriated to the U.S. and no U.S. tax was triggered on the  transfer of these funds to the European
subsidiary. 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

Net cash provided by operating activities increased by $278.8 million  in fiscal 2017  compared to

fiscal 2016 and decreased by $19.2 million in fiscal 2016 compared to fiscal 2015. The increase in  cash

66

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 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.  The decrease
in cash provided by operating activities in  fiscal 2016 was primarily  due to  lower cash flows  from the
timing of  shipments of large systems  from inventory and lower  cash flows from accounts receivable
partially offset by higher net income  and higher  accrued payroll  and accounts payable  balances.  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 through additional borrowings (as in our acquisition of  Rofin), existing cash balances and
cash flows from operations. 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 (the ‘‘Closing  Date’’),  we entered  into  a  Credit Agreement by and among

Coherent, Inc., Coherent Holding BV  & Co. K.G.  (formerly Coherent 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, as administrative agent and an
L/C Issuer, BAML as an L/C Issuer,  and MUFG 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  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.

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
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

67

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, as well as certain fees and  expenses of  the
administrative agent and the Lenders, in  accordance with the terms of the Credit Agreement.

On September 29, 2017, June 30, 2017 and March 31, 2017, we made voluntary principal payments
of 75.0 million Euros, 45.0 million Euros and 30.0 million Euros, respectively, on the Euro Term Loan.
As of September 30, 2017, the outstanding principal  amount  of the Euro Term Loan was 513.3 million
Euros. As of September 30, 2017, the outstanding principal  amount  of the Revolving Credit Facility was
10.0 million Euros.

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.

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 30, 2017.

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 paid $5.2 million
of debt issuance costs in fiscal 2016 and incurred approximately $26.4 million  of  debt  issuance  costs in

68

fiscal 2017. In the fourth quarter of fiscal  2016, and the first quarter  of  fiscal 2017, we recorded an
interest charge of $1.1 million and $2.7 million, respectively, in other income (expense) in our
consolidated statement of operations  related to the  debt  financing commitment. In fiscal 2017, we made
debt principal payments of $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 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.

Additional sources of cash available  to  us  were domestic and international  currency  lines  of  credit

and bank credit facilities totaling $29.2 million  as of September 30, 2017,  of which $23.3 million was
unused and available. As of September 30,  2017, we  had utilized $5.9 million of the  international credit
facilities as guarantees in Europe.

In fiscal  2015, under plans authorized by the Board of Directors, we repurchased and retired

1,302,323 shares of outstanding common  stock  at an  average price  of $57.59 per share  for a  total  of
$75.0 million.

Our ratio of current assets to current liabilities was 3.1:1 at September 30,  2017, compared to 4.0:1

at October 1, 2016. The decrease in our  ratio is primarily  due to the use of  cash in our  acquisition  of
Rofin and higher income taxes payable and  deferred income  partially offset by the impact of Rofin’s
current assets and current liabilities.  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  $35.0 million at
September 30, 2017. As of September 30,  2017, we had gross unrecognized tax benefits of $50.4 million

69

which  includes penalties and interest  of $2.8 million.  Approximately  $35.9 million has been recorded as
a noncurrent  liability. At this time, we are unable to make a  reasonably  reliable estimate of the timing
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 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),  stock-based compensation  expense of
$26.3 million, non-cash restructuring charges of $6.4  million, non-cash pension benefit of $5.4 million,
impairment charges of $2.9 million and  $1.5 million other,  partially offset by increases  in net deferred
tax assets of $19.8 million, the $5.4 million gain on business  combination, $4.9 million net cash flows
used by discontinued operations and $1.6  million excess tax  benefits from stock-based compensation
arrangements. Cash provided by operating activities  in fiscal  2016 was $105.3 million, which  included
net income of $87.5 million, depreciation  and amortization of $34.4  million,  stock-based  compensation
expense of $20.2 million and $0.9 million  other,  partially  offset  by cash used by operating  assets and
liabilities of $27.9 million (primarily increases in  inventories net of  increases in accrued  payroll  and
deferred income) and increases in net deferred tax assets of $9.8  million.

Cash used investing activities in fiscal 2017 of $810.3  million included $740.5 million net  of  cash

acquired to purchase Rofin, $61.8 million,  net, used to acquire property and equipment,  purchase  and
upgrade buildings, net of proceeds from  dispositions, $7.2 million net purchases of  available-for-sale
securities and $0.8 million net cash flows  used by discontinued operations.  Cash provided by investing
activities in fiscal 2016 of $103.4 million  included $152.2  million net  sales  and maturities  of
available-for-sale securities partially offset by $48.8 million, net, used to acquire  property and
equipment, purchase and upgrade buildings, net of  proceeds from dispositions.

Cash provided by financing activities  in fiscal 2017 was $506.0  million, which included

$539.1 million net borrowings $8.1 million  generated from our employee  purchase  plans and
$1.6 million excess tax benefits from  stock-based  compensation  arrangements partially offset  by
$26.4 million of debt issuance costs, $15.7 million  outflows due to net settlement  of  restricted stock and
$0.8 million payments to minority shareholders.  Cash  provided  by financing  activities in  fiscal  2016 was
$17.2 million, which included $20.0 million net  borrowings,  and $7.8 million generated from our
employee stock option and purchase  plans partially offset by $5.4 million outflows due to net
settlement of restricted stock and $5.2 million of debt issuance costs.

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

Changes in exchange rates in fiscal 2016  resulted in a decrease in cash balances of $2.2  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.

70

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
combinations, accounting for long-lived  assets (including  goodwill and intangible assets),  inventory
valuation, warranty reserves, stock-based  compensation  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.

71

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
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  2017, 2016 and 2015, we conducted a qualitative assessment of the goodwill  in the OLS
(formerly SLS) 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

72

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  2017, 2016 or 2015. As  such, it was not necessary to
perform the goodwill impairment test  at that  time in  any of  those fiscal years.

For our ILS (former CLC) reporting  unit  we elected to bypass the qualitative assessment in fiscal

2017, 2016 and 2015 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, 2016 and 2015.  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. Between the completion of that testing and the
end of the fourth quarter of fiscal 2017,  we noted no  indications  of  impairment or triggering  events for
either reporting unit to cause us to review goodwill for potential impairment.

At September 30, 2017, we had $417.7  million  of  goodwill ($102.2  million  OLS and $315.5 million
in ILS), $190.0 million of purchased  intangible assets and $278.9 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 market. 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.

Stock-Based Compensation

We  account for stock-based compensation using fair value.  We estimate  the fair value of

performance restricted stock units granted  using a Monte  Carlo simulation model. We use  historical
data to  estimate pre-vesting option forfeitures and record  stock-based compensation  expense only for
those awards that are expected to vest.  We value service-based restricted  stock units  using the intrinsic
value method and amortize the value on  a straight-line basis  over the restriction  period. We  value
performance restricted stock units using  a Monte Carlo simulation model and  amortize the value over
the performance period, with no adjustment  in future periods,  based upon  the actual shareholder
return  over the performance period.

U.S. Generally Accepted Accounting Principles  (‘‘GAAP’’)  requires the use  of option  pricing

models  that were not developed for use in valuing  employee stock options. The Black-Scholes
option-pricing model was developed  for use in estimating  the fair  value of short-lived exchange traded
options that have no vesting restrictions and are fully transferable. In addition, option-pricing models
require the input of highly subjective assumptions, including the options expected  life, the expected
price volatility of the underlying stock  and  an estimate of  expected forfeitures. Our computation  of
expected volatility considers historical  volatility and market-based implied volatility. Our  estimate of
expected forfeitures is based on historical  employee data and could differ from  actual forfeitures.

See Note 12, ‘‘Employee Stock Award and Benefit Plans’’  in the notes to  the Consolidated
Financial Statements for a description of  our stock-based employee  compensation  plans and the
assumptions we use to calculate the fair value  of  stock-based employee compensation.

Income Taxes

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

We  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 2017, we increased our valuation  allowance  on deferred  tax  assets by $11.1  million to

$28.7 million, primarily due to the increase  in California and  certain state research and  development

74

tax credits and the release of R&D tax reserves for California  and other states, 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  30, 2017, 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.

Federal and state income taxes have not been provided on  a portion of the unremitted earnings of
foreign subsidiaries because such earnings are intended  to  be  permanently reinvested. The total amount
of unremitted earnings of foreign subsidiaries for which we have not yet recorded federal  and state
income taxes was approximately $1,150 million at fiscal 2017 year-end. The amount of federal and state
income taxes that would be payable upon  repatriation of  such earnings is not practicably determinable.
We  have not, nor do we anticipate the  need to, repatriate funds to the United States to satisfy domestic
liquidity needs arising in the ordinary  course of business.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES  ABOUT MARKET  RISK

Market risk disclosures

We  are exposed to market risk related  to  changes in interest rates and foreign currency exchange

rates. We do not use derivative financial instruments for speculative or trading  purposes.

Interest rate sensitivity

A portion of our investment portfolio is  composed of fixed income securities. These securities are
subject to interest rate risk and will fall in value if market interest rates increase. If interest  rates  were
to increase immediately (whether due to changes in overall market rates or credit worthiness of the
issuers of our individual securities) and  uniformly by  10% from  levels at fiscal 2017 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 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. At fiscal  2016 year-end, the fair value of our available-for-sale debt
securities was $25.1 million, all of which was classified as short-term investments. There were no gross
unrealized gains and losses on available-for-sale debt securities at  fiscal  2017 or  2016 year-end.

We  are exposed to market risks related  to  fluctuations in  interest  rates related to our Euro Term
Loan. As of September 30, 2017, we owed  $606.7 million on  this  loan with an  interest  rate of 3.0%. We
performed a sensitivity analysis on the outstanding portion of our debt obligation as  of September 30,
2017. Should the current average interest  rate increase or decrease by 10%,  the resulting annual
increase or decrease to interest expense  would be approximately $1.8 million  as of September  30, 2017.

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 RMB. Additionally, we have

75

operations in different countries around the world with costs incurred in  other  local currencies, such  as
British Pound Sterling, Singapore Dollars  and Malaysian Ringgit. 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 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’’.

On August 1, 2016, we purchased forward contracts totaling 670.0 million Euro, with  a value  date
of November 30, 2016, to limit our foreign  exchange  risk related to the commitment of our term loan
(denominated in Euros) in an amount  of the Euro equivalent of $750.0 million to finance the
U.S. dollar payment for the acquisition of Rofin. In the fourth quarter of fiscal  2016, we  recognized an
unrealized loss of $2.2 million on these hedges.  Subsequent to October 1, 2016, we settled these hedges
at a net gain of $3.1 million, resulting  in  a realized gain of  $5.3 million  in the first quarter of fiscal
2017. 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
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 30, 2017, approximately  $300.0 million of our cash, cash  equivalents and short-term

investments were held outside the U.S.  in  certain of  our foreign operations, $263.2 million of which  was
denominated in currencies other than the U.S. dollar. See Note 3,  ‘‘Business  Combinations’’ in our
Notes to Consolidated Financial Statements under Item 15 of this annual report  for further discussion
of the completion of our acquisition of  Rofin  and the  use of cash to finance the acquisition.

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 30, 2017. 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 30, 2017 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 30, 2017, 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 30, 2017. The effectiveness of our internal control over financial reporting as
of September 30, 2017 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.

78

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
are in the process of integrating Rofin  into our systems and control  environment as  of  September 30,
2017. We believe that we have taken the  necessary  steps to monitor and maintain appropriate internal
control over financial reporting during  this  integration. Other than the impact of this business
acquisition, 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 30,  2017.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders  of
Coherent, Inc.
Santa Clara, CA

We  have audited the internal control over  financial reporting of  Coherent,  Inc. and  its  subsidiaries

(collectively, the ‘‘Company’’) as of September 30, 2017,  based on the criteria established in Internal
Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations  of  the
Treadway Commission. 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  conducted our audit in accordance with the standards of  the Public Company Accounting
Oversight Board (United States). 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.

A company’s internal control over financial reporting is a process designed by, or  under the

supervision of, the company’s principal executive and principal financial  officers,  or persons performing
similar functions, and effected by the company’s board of directors, management, and other personnel
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 the inherent limitations of internal  control over  financial reporting, including  the
possibility of collusion or improper management override of controls, material misstatements  due  to
error or fraud may not be prevented or detected  on a  timely basis. Also, projections of any evaluation
of the effectiveness of the internal control over financial reporting to future periods are subject  to  the
risk that the controls may become inadequate  because of changes in conditions, or  that  the degree of
compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal  control  over

financial reporting as of September 30, 2017,  based on the criteria established in Internal Control—
Integrated Framework (2013) issued by the Committee of Sponsoring  Organizations  of  the Treadway
Commission.

We  have also audited, in accordance  with the standards of  the Public Company Accounting
Oversight Board (United States), the  consolidated financial statements as  of  and for the year ended
September 30, 2017, of the Company and our report dated  November 28,  2017, expressed an
unqualified opinion on those consolidated  financial statements.

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  2017 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 30, 2017 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.
Santa Clara, CA

We  have audited the accompanying consolidated balance sheets of Coherent, Inc.  and its
subsidiaries (collectively, the ‘‘Company’’) as of  September  30, 2017 and  October 1, 2016, 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  30, 2017. These consolidated financial
statements are the responsibility of the Company’s management. Our responsibility is to express an
opinion on these consolidated financial  statements  based on our audits.

We  conducted our audits in accordance with the standards  of  the Public Company Accounting
Oversight Board (United States). Those  standards require that we  plan and perform the audit to obtain
reasonable assurance about whether  the  financial  statements are free  of material misstatement.  An
audit includes examining, on a test basis, evidence  supporting the amounts and disclosures  in the
financial statements. An audit also includes assessing the accounting  principles used  and significant
estimates made by management, as well as  evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable  basis for our opinion.

In our opinion, such consolidated financial  statements  present fairly, in  all  material  respects, the

financial position of the Company as of  September 30, 2017 and October  1, 2016, and the results of its
operations and its cash flows for each  of  the  three years in the  period  ended September 30,  2017, 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), the  Company’s  internal control over financial reporting as  of
September 30, 2017, 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 28, 2017 expressed an unqualified opinion on the Company’s  internal control over
financial reporting.

2. SIGNIFICANT ACCOUNTING POLICIES

Fiscal Year

Our fiscal year ends on the Saturday  closest to September 30. Fiscal years 2017,  2016 and 2015

ended on September 30, 2017, October 1, 2016 and October 3, 2015, respectively, and are referred to
in these financial statements as fiscal  2017, fiscal 2016,  and fiscal 2015 for  convenience. Fiscal years
2017 and 2016 include 52 weeks and fiscal year  2015 includes 53  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’’). The significant  accounting policies of  Rofin  have been aligned  to  conform to
those of Coherent, and the consolidated  financial statements  include the results of Rofin as  of  the
acquisition date.

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  2017 year-end, cash and cash equivalents included cash,  money
market funds, commercial paper and  U.S.  agency obligations.

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 2017 year-end,
the majority of our short-term investments were in  U.S. Treasury and agency  obligations and  corporate
notes and 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 30, 2017, we held cash and cash equivalents  and short-term investments outside the U.S. in
certain of our foreign operations totaling  approximately $300.0 million,  $263.2 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 19.0% and 18.0%  of accounts receivable  at fiscal 2017  and fiscal
2016 year-end. We had another customer who accounted for 18.7% of accounts receivable  at fiscal
2016 year-end.

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 and Malaysian  Ringgit.  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

99

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

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  2017 year-end, gross expected  future cash flows of
$6.1 million would be required to fulfill these  obligations.

The following table reconciles changes in  our  asset retirement liability for fiscal 2017  and 2016 (in

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 2017, we recorded a $2.9 million  impairment charge  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 Assets Held for Sale’’). In fiscal 2016, there
were no significant asset impairments  recorded.  In  fiscal 2015, we recorded a $2.0 million  impairment
of our investment  in SiOnyx in fiscal  2015.

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 2017  and 2016  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, 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  both fiscal 2017 and 2016. (See Note  7,
‘‘Goodwill and Intangible Assets’’ for additional discussion of the fiscal 2017  analysis.)

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

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
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

103

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

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.

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

We  treat third party and government  funding of our research and development activity, where  we
are the primary beneficiary of such work conducted, as  a reduction  of research and  development cost.
Research and development reimbursements of $2.9  million,  $2.7 million and  $2.5 million were  offset
against research and development costs in fiscal  2017, 2016 and 2015,  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 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. Accumulated other comprehensive income  (loss) (net  of  tax) at fiscal 2016 year-end is
substantially comprised of accumulated translation adjustments  of  $(8.6) million and unrealized gain  on
marketable equity securities of $3.3 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  contracts,
using the treasury  stock method.

The following table presents information necessary to calculate basic and diluted  earnings per

Stock-Based Compensation

We  account for stock-based compensation using the  fair value of the  awards granted. 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,
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

106

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

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.

Federal and state income taxes have not been provided on  a portion of the unremitted earnings of
foreign subsidiaries because such earnings are intended  to  be  permanently reinvested. The total amount
of unremitted earnings of foreign subsidiaries for which we have not yet recorded federal  and state
income taxes was approximately $1,150 million and $574 million at  fiscal 2017 and 2016  year-end,
respectively. The amount of federal and state income taxes  that would  be payable upon repatriation  of
such earnings is not practicably determinable. We have not, nor do we  anticipate the need to, repatriate
funds  to the United States to satisfy domestic liquidity  needs arising  in the ordinary course of business.

Adoption of New Accounting Pronouncements

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 existing guidance, when
computing the implied fair value of goodwill under Step 2,  an entity is required to perform procedures
to determine the fair value at the impairment testing date  of  its  assets and liabilities following the
procedure that would be required in determining the  fair value of assets  acquired  and liabilities
assumed in a business combination. Under the amendments in  this  update, an entity should simply
perform its annual, or interim, goodwill impairment test  by  comparing the fair value  of  a reporting unit
with its carrying amount. An entity should 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 2021 which begins on  October 4,  2020. We elected to early adopt  the standard in  the
fourth quarter of fiscal 2017 and the  adoption resulted in no impact  on  our consolidated financial
statements and disclosures.

In November 2016, the FASB issued amended guidance that require a statement  of cash  flows to

explain the change during the period  in the total of  cash, cash equivalents, and  amounts generally
described as restricted cash or restricted cash equivalents. Therefore,  amounts  generally  described as
restricted cash and restricted cash equivalents  should be included with cash and cash  equivalents when
reconciling the beginning-of-period and end-of-period total amounts shown  on the statement of  cash
flows. The new standard will become  effective for our fiscal  year beginning September 30, 2018.  We
elected to early adopt the standard in  the first quarter  of  fiscal  2017 on a retrospective basis with no
impact on our consolidated financial  statements and disclosures.

In April 2015, the FASB issued amended guidance that simplifies the  presentation of debt issuance

costs by requiring that debt issuance costs related to a recognized debt liability be presented in the
balance sheet as a direct deduction from  the carrying  amount  of that  debt  liability,  consistent with  debt
discounts. The recognition and measurement  guidance for  debt issuance costs are not affected by the
amended guidance. The new standard  became effective for our fiscal year beginning October  2, 2016.
We  elected to early adopt the standard in  the second quarter of fiscal  2016 and  had recorded  debt
issuance costs of $5.2 million in Other assets  as of October 1, 2016  for the  debt  commitment we
entered into in the second quarter of  fiscal 2016  because the  debt  was  not  outstanding as of  October 1,
2016. The debt issuance costs related  to  the term loan facility were reclassified  to  debt in the first
quarter of fiscal 2017 when we drew down the  debt.

Recently Issued Accounting Pronouncements

In August 2017, the FASB issued amended  guidance to address current U.S.  GAAP’s limitation on

how an entity can designate the hedged  risk in certain  cash flow and fair  value hedging  relationships.
This amendment better aligns the 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 accumulated 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 year 2020 which begins  on September  29, 2019. We are currently
assessing the impact of this amended guidance.

In May 2017, the FASB issued amended guidance about which changes to the terms  or conditions
of a share-based payment require an  entity to apply modification accounting.  Under the  new guidance,
an entity should account for the effects  of  a modification unless,  comparing to the original award prior
to modification, the fair value, the vesting  conditions and the classification as  equity or as  a liability of
the modified award are all the same. The amendments in this update should be applied prospectively
to an award modified on or after the adoption date.  The  new  standard  will  become effective for our
fiscal year 2019 which begins on September 30, 2018. We  do not expect the adoption of this standard to
have a material impact on our financial  statements.

In October 2016, 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 will become  effective in the first quarter of  our
fiscal 2019. We are currently assessing the  impact of this amended  guidance and  are planning  to  adopt
it in the first quarter of fiscal 2018.

In May 2016, accounting guidance was issued  to  clarify  the not yet effective revenue  recognition

guidance issued in May 2014. This additional guidance does not change the core  principle of the
revenue recognition guidance issued in  May 2014, rather, it provides clarification  of  accounting for
collections of sales taxes as well as recognition of  revenue (i) associated  with contract  modifications,
(ii) for noncash consideration, and (iii)  based  on the  collectability of the consideration from the
customer. The guidance also specifies when a contract should be considered ‘‘completed’’ for purposes
of applying the transition guidance. The effective date and transition requirements for  this  guidance are
the same as the effective date and transition requirements for  the  guidance previously issued in 2014,
which  is effective for our fiscal year 2019 which begins on  September 30, 2018. We are  currently
evaluating the new guidance and have not determined  the impact this standard may have on our
financial statements nor have we decided  upon the method of adoption.

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,

108

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

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 APIC
pool and significantly reduces the complexity  and  cost of accounting for excess tax benefits  and tax
deficiencies. The new standard will become effective for our fiscal year beginning October  1, 2017.
Upon our adoption in the first quarter of fiscal 2018, we expect to recognize a windfall tax benefit as a
cumulative effect adjustment increase  to  our opening  retained  earnings of approximately $20.0 million
together with a comparable increase in  deferred tax  assets.

In February 2016, the FASB issued amended  guidance to increase  transparency and comparability

among organizations by recognizing lease assets  and  lease  liabilities  on  the balance sheet  and disclosing
key information about leasing arrangements.  The  new guidance  clarifies the criteria for distinguishing
between a finance lease and operating lease,  as well  as classification between the two types  of  leases,
which  is substantially unchanged from the  previous lease guidance.  Further,  the new guidance  requires
a lessee to recognize in the statement of financial position a  liability  to  make lease payments (the lease
liability) and a right-of-use asset, initially  measured at the present value of the lease  payments. For
finance leases, a lessee should recognize interest on the  lease liability separately from amortization of
the right-of-use asset. For operating leases, a lessee should recognize a  single lease cost, calculated  so
that the cost of the lease is allocated over  the lease  term on  a  generally straight-line basis.  For leases
with a term of 12 months or less, a lessee  is permitted to make an accounting policy  election not to
recognize lease assets and lease liabilities. The new  standard will become effective for our fiscal year
2020 which begins on September 29, 2019.  We  are currently assessing the impact of this amended
guidance and the timing of adoption.

In January 2016, the FASB issued amended guidance that  revises the recognition and measurement

of financial instruments. The new guidance  requires equity investments (except those  accounted for
under the equity method of accounting, or those that result in consolidation of the  investee) to be
measured at fair value with changes  in fair value recognized in net income, requires  public  business
entities to use the exit price notion when  measuring the  fair value of financial instruments for
disclosure purposes, requires separate  presentation of financial assets  and  financial  liabilities  by
measurement category and form of financial asset, and  eliminates the requirement  for public business
entities to disclose the method(s) and significant  assumptions used to estimate the fair value that is
required to be disclosed for financial instruments measured at amortized cost. The new  standard will
become  effective for our fiscal year 2019 which begins  on September  30, 2018. We are currently
assessing the impact of this amended guidance and the timing of adoption.

3. BUSINESS COMBINATIONS

Fiscal 2017 Acquisitions

Rofin

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

dated March  16, 2016. Rofin is 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  have reported this
business separately as a discontinued operation  until its  divestiture (See Note 18,  ‘‘Discontinued
Operations’’). 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 19,  ‘‘Subsequent Event’’.

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. 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 expect that all such goodwill will not
be deductible for tax purposes.

In the third quarter of fiscal 2017, we  re-evaluated the carrying value of the Hull Business that has
been presented as assets held for sale  since  the acquisition. As  a result,  approximately  $33.9 million of
goodwill was reallocated from the assets  held for sale to the remaining business acquired  as we  were
within the remeasurement period.

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 the year ended September 30,  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  as of September  30, 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

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 have not yet
reached technological feasibility. 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. The projects have not been completed as of
September 30, 2017.

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

expenses in our consolidated statements  of  operations during the year ended September 30, 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  the year ended September  30, 2017 was
approximately $434.9 million and $48.1  million,  respectively.

Unaudited Pro Forma Information

The following unaudited pro forma financial information presents our combined results of

operations as if the acquisition of Rofin and  the related  issuance  of  our Euro  Term Loan  had occurred
on October 4, 2015. The unaudited pro  forma financial  information is  not necessarily indicative of what
our  consolidated results of operations  actually would have been had the acquisition been completed  on
October 4, 2015. In addition, the unaudited  pro forma  financial information  does not attempt to project
the future results of operations of the combined  company.  The actual results may differ significantly
from the pro forma results presented  here due to many factors.

The purchase price allocated to goodwill was finalized  in the first quarter of fiscal  2016, with an
increase of $0.4 million and a corresponding decrease of $0.4 million  to  tangible  assets, and has been
updated from the preliminary allocation in the  fourth quarter  of fiscal 2015.

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 useful lives of three to

None of the goodwill from this purchase  is deductible for  tax purposes.

We  expensed $0.1 million of acquisition-related  costs as selling, general and  administrative

expenses in our consolidated statements  of  operations for  our fiscal year  2015.

Tinsley Optics

On July 27, 2015, we acquired the assets  and  certain liabilities of the Tinsley Optics (‘‘Tinsley’’)

business from L-3 Communications Corporation for approximately $4.3 million, excluding transaction
costs. Tinsley is a specialized manufacturer  of high precision optical  components and  subsystems sold
primarily in the aerospace and defense industry. Tinsley manufactures the large form  factor optics for

The purchase price was lower than the fair value of net  assets purchased,  resulting in a  gain of
$1.3 million recorded as a separate line item in our consolidated statements of  operations for our fiscal
year 2015. The Company reassessed the  recognition and  measurement of  identifiable assets acquired
and liabilities assumed and concluded  that all acquired assets and assumed  liabilities were  recognized
and that the valuation procedures and resulting measures were  appropriate.

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

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 30, 2017  and October 1, 2016,  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 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.

(2) 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.

4. FAIR VALUES (Continued)

(3) 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’’.

(4) 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).

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 2017, 2016, and 2015, we recognized a gain of $17.8  million, a loss of $10.5  million

and a loss of $4.3 million, respectively,  in other income (expense) for derivative  instruments not
designated as hedging instruments.

Designated Derivatives

Cash flow hedges related to anticipated  transactions are designated and documented  at the
inception of the hedge when we enter  into contracts for specific  future transactions. Cash  flow hedges
are evaluated for effectiveness quarterly. The  effective portion of the gain or loss on these  hedges  is
reported as a component of OCI in stockholder’s  equity and is reclassified  into  earnings when  the
underlying transaction affects earnings. We had no  cash flow hedges outstanding  at September 30, 2017
or October 1, 2016. Changes in the fair value of currency forward contracts due to changes in  time
value are excluded from the assessment  of effectiveness and recognized  in other income (expense) as
incurred. We classify the cash flows from the foreign exchange forward contracts that are accounted for
as cash flow hedges in the same section  as the underlying item, primarily  within cash flows from
operating activities since we do not designate our cash flow hedges  as investing or financing activities.

In fiscal  2014, we had entered into certain derivative forward  contracts to sell  Japanese  Yen  and

buy Euro to hedge revenue exposures  related to our photonics-based solutions in Asia. In  order  to
facilitate the hedge, we transacted with counterparties  in the U.S.  directly and  then allocated the hedge
contracts to our affiliates through a back-to-back relationship with our German subsidiary. The German

119

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

6. DERIVATIVE INSTRUMENTS AND  HEDGING  ACTIVITIES (Continued)

subsidiary designated these hedge contracts as cash flow  hedges  under ASC 815. The hedges were
settled in fiscal 2016.

During  fiscal 2017, we did not have any activities related  to designated cash flow  hedges.  During

fiscal 2016, we recorded losses in OCI and in other  income (expense) and reclassified  losses from OCI
into revenue related to the accounting  for  derivatives  designated as  cash flow hedges. These losses and
reclassifications were not material. In fiscal 2015,  we recorded a gain of $0.6  million in OCI and a
$0.1 million loss in other income (expense) as  well as reclassified $0.2 million of gains from  OCI into
revenue and $1.7 million of losses into cost of  sales related to the accounting  for derivatives designated
as cash flow hedges.

During  the fiscal year ended October 1, 2016,  we recognized a loss of less than $0.1 million in
other income (expense) as ineffectiveness  related to a portion  of an anticipated hedged transaction  that
failed to occur within the original hedge period  plus two  months. The remainder of the hedged
transaction occurred as expected and  effective amounts  were  recognized in  revenue or cost of sales.

The amounts that will be reclassified  from  OCI to earnings are generally offset by the recognition
of the hedged transactions (e.g., anticipated cost  of sales) in earnings,  thereby achieving the realization
of prices contemplated by the underlying risk management strategies,  and  will vary from  the expected
amounts presented above as a result  of  changes in  foreign exchange rates.

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
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  2017 annual  testing, we
performed a qualitative assessment of the  goodwill for our  OLS  reporting unit during  the
fourth quarter of fiscal 2017 using the  opening balance sheet as  of  the first day  of  the fourth  quarter

120

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

7. GOODWILL AND INTANGIBLE ASSETS (Continued)

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 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 reporting unit. Based  on our assessment,
goodwill in the OLS reporting unit was not impaired  as of the  first day of the fourth quarter of fiscal
2017. As such, it was not necessary to  perform the goodwill impairment test at that time.  For the  ILS
reporting unit, we  elected to bypass the qualitative assessment  and proceed directly to performing the
goodwill impairment test. We performed  our test using  the opening  balance  sheet  as of the first day  of
the fourth quarter and noted no impairment.  We determined  the  fair value of the ILS  reporting unit
for the test using a 50-50% weighting  of  the  Income (discounted cash flow) approach and  Market
(market comparable) approach. Management completed and reviewed the results of the impairment
analysis and concluded that an impairment charge was not required as the estimated  fair value  of the
ILS reporting unit was significantly in excess of  its carrying value.  Between  the completion of that
testing and the end of the fourth quarter of  fiscal  2017, we noted no indications of impairment  or
triggering events with either reporting unit to cause us to review  goodwill  for potential impairment.

(1) Gross amount of goodwill for our  ILS segment was $328.5 million  at September 30, 2017
and $17.4 million at October 1, 2016,  respectively. At both September 30, 2017  and
October 1, 2016, 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 $110.9  million and $105.7 million at

September 30, 2017 and October 1, 2016, respectively. At both September 30, 2017 and
October 1, 2016, 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  2016, we did not have any impairment  of  intangible assets as a result  of the impairment

analysis.

The weighted average remaining amortization periods  for existing  technology, patents, customer

lists and trade names are approximately 3.2 years, 4.1 years, 7.4 years and 2.1 years, respectively.
Amortization expense for intangible  assets during fiscal years 2017, 2016, and 2015 was  $60.6 million,
$8.5 million and $8.2 million, respectively.  The change in accumulated amortization also includes

9. BORROWINGS

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.

On September 29, 2017, June 30, 2017 and March 31, 2017, we made voluntary principal payments
of 75.0 million Euros, 45.0 million Euros and 30.0 million Euros, respectively, on the Euro Term Loan.
As of September 30, 2017, the outstanding principal  amount  of the Euro Term Loan was 513.3 million
Euros. As of 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
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

124

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

9. BORROWINGS (Continued)

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, as well as certain fees and  expenses of  the
administrative agent and the lenders, in accordance  with the terms  of the Credit Agreement.

The Credit Agreement requires the Borrower to make scheduled quarterly  payments on the

Euro  Term Loan of 0.25% of the original principal amount of the  Euro  Term Loan, with  any remaining
principal payable at maturity. A commitment fee accrues on any unused portion  of the revolving  loan
commitments under the Credit Agreement  at a  rate  of  0.375% or  0.5%  depending  on the consolidated
total gross leverage ratio at any time of determination. The Borrower is also obligated to pay other
customary fees for a credit facility of  this size  and  type.

On the Closing Date, we and certain  of  our  direct and indirect subsidiaries, as guarantors,

provided an unconditional guaranty of  all obligations of the  Borrower  and  the other loan parties  arising
under the Credit Agreement, the other  loan documents and under swap contracts and treasury
management agreements with the lenders or their affiliates (with  certain limited exceptions).  The
Borrower and the guarantors have also  granted security interests in  substantially  all  of their  assets to
secure such obligations.

The Credit Agreement contains customary affirmative 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

125

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 30, 2017.

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.

For the year ended September 30, 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 $29.2 million as  of September 30, 2017,  of which $23.3  million  was  unused and
available. As of September 30, 2017, we had utilized  $5.9 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 30, 2017 we did
not have any material indemnification claims that  were probable  or reasonably possible.

Commitments

We  lease several of our facilities under  operating leases  and recognize  rent  expense on a

straight-line basis over the life of the leases.

$62,706

Rent expense was $16.5 million, $12.6 million and $11.0 million in fiscal  2017, 2016 and 2015,

respectively.

As of September 30, 2017, we had total purchase commitments  for inventory of approximately

$180.0 million and purchase obligations for  fixed  assets and  services of $23.9  million compared to
$73.7 million of purchase commitments for  inventory and  $12.2 million of purchase obligations for fixed
assets and services at October 1, 2016.  The inventory increase  was primarily due to the acquisition of
Rofin in the first quarter of fiscal 2017 and higher  commitments  to  support  the higher shipments of

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

10. COMMITMENTS AND CONTINGENCIES (Continued)

large ELA tools used in the flat panel  display market. The fixed assets  and services  increase was
primarily due to expansion of our manufacturing  capacity in G¨ottingen, Germany, the upgrade of
certain of our production facilities in California and the acquisition  of  Rofin.

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 alleges that the
use of certain of the Company’s lasers infringes 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 seeks unspecified compensatory damages, the cost of court proceedings and seeks 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 has appealed this decision to the  Federal Court of Justice, the  highest civil jurisdiction court in
Germany. The infringement action is  currently  stayed pending the  outcome of such appeal.
Management has made an accrual with respect to this matter  and has determined, based on its current
knowledge, that the amount or range  of reasonably  possible losses in excess of the amounts already
accrued is not reasonably estimable.  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  duty calculations and payments are audited
by government agencies. During the  second quarter  of  fiscal  2016, we concluded an audit in  South
Korea for customs duties and value added tax for the period  March 2009  to  March 2014. We paid
$1.6 million related to this matter in the second quarter of fiscal 2016 and have no remaining accrual at
October 1, 2016.

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 July 25, 2014, our Board of Directors authorized  a buyback  program whereby we were

authorized to repurchase up to $25.0  million of our common  stock from time to time  through July  31,
2015. During the first and second quarters of fiscal 2015, we repurchased and retired 434,114 shares of
outstanding common stock under this  plan  at an  average price of $57.59 per share for a total  of
$25.0 million.

On January 21, 2015, our Board of Directors  authorized an  additional stock repurchase program to

repurchase up to $25.0 million of our  outstanding common stock from time to time through

of outstanding common stock under this  plan at an average price of $58.05 per share for  a total of
$25.0 million.

On August 25, 2015, our Board of Directors  authorized an  additional  stock repurchase  program to
repurchase up to $25.0 million of our  outstanding common stock from time to time through August  31,
2016. During the fourth quarter of fiscal  2015, we  repurchased  and retired  437,534 shares  of
outstanding common stock under this  plan  at an  average price  of $57.14 per share  for a  total  of
$25.0 million.

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

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 2017, 2016,  and 2015 were
$4.8 million, $4.1 million and $3.6 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 2017, 2016  and 2015, a total of 95,678 shares,
141,340 shares and 132,004 shares, respectively, were purchased by and distributed to employees at  an
average price of $81.82, $46.81 and $51.34 per share, respectively. At  fiscal 2017 year-end, we  had
424,882 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 4,950,603 shares remained available  for  grant at  fiscal  2017 year-end.
At fiscal 2017 year-end, all outstanding stock  options and restricted stock  units have been issued under
plans approved by our shareholders.

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.

COHERENT, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

12. EMPLOYEE STOCK AWARD AND  BENEFIT PLANS  (Continued)

(cid:127) The service based restricted stock awards generally vest within  three years from the  date of

grant.

(cid:127) The service based restricted stock unit awards are generally subject to annual vesting over three

years from the date of grant.

(cid:127) 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.

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 2017, 2016

and  2015 were estimated using the following weighted-average assumptions:

Expected life in years . . . . . . . . . . . . . . . . . . . . . . . . .
Expected volatility . . . . . . . . . . . . . . . . . . . . . . . . . . .

Performance Restricted Stock Units

We  grant performance restricted stock  units to officers  and certain  employees. The performance
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
Russell 1000 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:

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, based on the portion of the total  service period of the underlying options that
have not been completed by the merger  date.

Total stock-based compensation cost capitalized as part of inventory during fiscal 2017 was
$3.6 million; $3.3 million was amortized into income  during fiscal 2017, which  includes amounts
capitalized in fiscal 2017 and amounts carried over from  fiscal 2016.  Total stock-based compensation
cost capitalized as part of inventory during fiscal  2016 was $2.7 million; $2.6  million was  amortized into
income during fiscal 2016, which includes amounts  capitalized in  fiscal 2016 and amounts carried over
from fiscal 2015.

12. EMPLOYEE STOCK AWARD AND  BENEFIT PLANS  (Continued)

At fiscal 2017 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 $31.7 million.
We  do not estimate forfeitures. This cost  will be amortized on a straight-line  basis over  a weighted-
average period of approximately 1.5 years.

The stock option exercise tax benefits 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  and  2015, we  did not generate
any excess tax benefits as cash flows from  financing  activities.

Stock Awards Activity

At fiscal 2017, 2016 and 2015 year-end, we had 24,000, 33,500  and 86,000 shares subject to vested

stock options outstanding. The vested  stock options at fiscal 2017  are  held by one non-employee
director.

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 2017,  89,000 in  fiscal  2016 and 91,000 in  fiscal
2015; tax payments made were $15.7 million,  $5.4 million and $5.3 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 year 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
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.

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. 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.

Allocation

We  employ a total return investment approach whereby a mix  of equity, debt securities and
government securities are used to maximize  the long-term  return of plan assets for a prudent level of
risk. The intent of this strategy is to minimize plan expenses  by maximizing investment returns within
that prudent level of risk. Furthermore,  equity investments are diversified across U.S. and  non-U.S.
stocks as well as growth, value and small  and large capitalizations. Additionally, cash balances are
maintained at levels adequate to meet near-term  plan expenses and benefit payments. Investment risk
is measured and monitored on an ongoing basis through semi-annual  investment portfolio reviews.

Investments in our defined benefit plan are stated at fair value. Level 1 assets are  valued using
quoted market prices that represent the  asset value of the shares  held by  the trusts. The  level 2  assets
are investments in pooled funds, which are valued using a model to reflect the valuation of their
underlying assets that are publicly traded with observable values. The fair  value of level 3 pension plan
assets are measured by compiling the  portfolio holdings and independently valuing the  securities in
those portfolios.

The fair values of our pension plan assets, by level  within the  fair value hierarchy, at

September 30, 2017 are as follows:

23.3%

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).

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 $1.1  million and
$0.7 million in fiscal 2017 and fiscal 2016, respectively. There is  no tax benefit for fiscal 2015  due  to  the
utilization of net operating loss.

In determining our fiscal 2017 and 2016 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 2017 and  2016 year-ends.

During  fiscal 2017, we increased our valuation allowance on deferred  tax  assets by $11.1  million to
$28.7 million, primarily due to the increase in California and  other states research and  development tax
credits and the release of R&D tax reserves for California and other states, 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 30, 2017, 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  have various tax attribute carryforwards which include the following:

(cid:127) Foreign gross net operating loss carryforwards  are $48.5  million, of which  $39.9 million have no
expiration date and $8.6 million have various expiration dates beginning in  fiscal year  2018.
Among the total of $48.5 million foreign  net operating  loss  carryforwards,  a valuation  allowance
of $8.9 million has been provided for certain jurisdictions since the  recovery of the carryforwards
are uncertain. Federal and certain state  gross net operating  loss carryforwards are $9.2 million
and $30.8 million, respectively, which were acquired from  our Rofin-Sinar acquisition. A  full
valuation allowance against certain other state net operating losses has  been recorded. California
gross  net operating loss carryforward is $0.3 million  and  is scheduled  to  expire in  fiscal year
2032. The tax benefit relating to approximately $0.3 million of  the  California  net operating loss
carryforward is off-balance sheet.

(cid:127) Federal R&D credit carryforwards  of $30.2 million  are scheduled to expire  beginning  in fiscal

year 2024. The tax benefit relating to  approximately $4.9  million of the  federal tax credit
carryforwards is off-balance sheet. California R&D credit carryforwards of  $27.2 million have no
expiration date. The tax benefit relating  to  approximately $1.4 million of the  state tax credit
carryforwards is off-balance sheet with a full  valuation  allowance. The total of  $22.1 million
valuation allowance, before federal benefit, has been recorded  against  California R&D credit
carryforwards since the recovery of the  carryforwards  are uncertain. Other states R&D credit
carryforwards of $3.2 million are scheduled to expire  beginning in  fiscal  year  2018. A  valuation
allowance totaling $2.7 million, before federal benefit,  has  been recorded against certain state
R&D credit carryforwards since the recovery of the carryforwards  is uncertain.

(cid:127) Federal foreign tax credit carryforwards of $14.9  million are scheduled  to  expire beginning in

fiscal year 2018. The tax benefit relating  to  approximately  $14.9  million of the  federal foreign  tax
credit carryforwards is off-balance sheet.

We  are subject to taxation and file income  tax  returns in the U.S. federal  jurisdiction  and in many

state and foreign jurisdictions. For U.S. federal income  tax purposes, all  years  prior to fiscal 2011 are
closed. In September 2017, the Internal  Revenue Service (IRS) completed  its audit of Coherent Inc.’s
fiscal 2013 tax return with no adjustment.  The extension of the statutes of limitations for its  fiscal 2011
and 2012 tax returns will be closed on June  30, 2018. In our major  foreign  jurisdictions and  our  major
state jurisdictions,  the years prior to fiscal  2011 and 2013,  respectively,  are closed to examination.
Earlier years in our various jurisdictions  may remain open for adjustment  to  the extent that we  have
tax attribute carryforwards from those years.

In July 2015 and March 2016, Coherent Kaiserslautern GmbH (formerly Lumera Laser GmbH)

received tax audit notices for the fiscal  years  2010 to 2014. The audit began in August 2015. We
acquired the shares of Lumera Laser  GmbH  in December  2012 and,  pursuant to the terms  of the
acquisition agreement, we should not have  responsibility for any assessments related  to  the
pre-acquisition period. In July, 2016, Coherent Holding GmbH and Coherent Deutschland GmbH  each
received a tax audit notice for the fiscal  years  2011 to 2014. The  audit began in  August  2016. In
November 2016, Coherent GmbH, Coherent LaserSystems GmbH &  Co. KG and Coherent
Germany GmbH received audit notices  for the period that they were in existence during the fiscal years
2011 through 2014. The audit work began in January 2017. In  the fourth  quarter  of fiscal 2017, all
German tax audits were extended to fiscal  2015 and  are currently in  progress.

We  regularly engage in discussions and negotiations with  tax authorities  regarding tax matters  in

various jurisdictions and management  believes that it has adequately  provided reserves for any
adjustments that may result from tax  examinations.

As of September 30, 2017, the total amount  of  gross unrecognized tax benefits including gross
interest and penalties was $50.4 million,  of which $34.7 million,  if recognized, would affect our effective
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 30, 2017, the total amount  of gross interest and penalties  accrued was $2.8 million and it is
classified as long-term taxes payable in  the consolidated balance sheets.  As of  October 1,  2016, we  had
accrued $0.2 million for the gross interest  and penalties and  it is  classified as long-term taxes payable in
the consolidated balance sheets.

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
Industrial Lasers & Systems 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 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
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 and  human resources)  and are  included
in the results below under Corporate and other in the reconciliation of  operating results. Management
does not consider unallocated Corporate  and other costs in  its  measurement of segment performance.

segments and a reconciliation of our total  income  from continuing operations to income from

during fiscal 2017, 2016 and 2015, 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 in fiscal 2017 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. These activities  resulted in charges

145

COHERENT, INC. AND SUBSIDIARIES

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 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

At September 30, 2017, $1.3 million of accrued severance related  costs  were included in other
current liabilities. The current year severance  related costs 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 exit from certain product lines  as well  as the consolidation  of  sales
and distribution offices. The current  year  asset  write-offs  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,  $11.4 million of restructuring costs
was incurred in the ILS segment and  $0.9 million was incurred in the OLS segment  in fiscal 2017.
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 ASSETS HELD FOR SALE

Discontinued Operations

Discontinued operations are comprised of Rofin’s low power CO2 laser business based in Hull,

United Kingdom (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 will
report this business separately as a discontinued operation until it is divested.  In the  third  quarter  of
fiscal 2017, we entered into an agreement with  a potential purchaser of the Hull Business and
submitted our proposed purchaser to the European Commission  for  its  review  and approval, including
the terms under which the purchase and  operation  of  the Hull Business  will  occur. 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 19, ‘‘Subsequent Event’’.

For financial statement purposes, the results of operations for this  discontinued business have  been

segregated from those of the continuing  operations  and are presented in our consolidated financial
statements as discontinued operations  and the  net assets of the remaining discontinued business have
been presented as current assets and  current liabilities held for sale.

19. SUBSEQUENT EVENT

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

CO2 laser business based in Hull, United  Kingdom (the ‘‘Hull Business’’), and  have reported this
business separately as a discontinued operation  until its  divestiture. In the third quarter of fiscal  2017,
we entered into an agreement with a potential  purchaser of the  Hull Business and submitted  our
proposed purchaser to the European Commission for its review and approval,  including the  terms
under which the purchase and operation of the Hull Business will  occur.  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. We expect to  record an immaterial gain on  the divestiture in the first quarter of
fiscal 2018.
