EXHIBIT 99.1

                              IMPORTANT FACTORS

FOREIGN OPERATIONS

         The  Company  conducts a portion of its  operations  outside the United
States and its business is subject to risks  associated with many factors beyond
its control,  such as  fluctuations in foreign  currency  rates,  instability of
foreign  economies  and  governments,  and changes in U.S.  and foreign laws and
policies   affecting   trade  and   investment.   The  Company  owns  or  leases
manufacturing and assembling  facilities in Ennis,  Ireland;  Bombay,  India and
Hong Kong and is in the process of  establishing a joint venture in The People's
Republic  of China.  Although  the Company has not  experienced  any  materially
adverse  effects  with  respect  to its  foreign  operations  arising  from such
factors,  there can be no  assurance  that such  problems  will not arise in the
future.


SALES TO FOREIGN CUSTOMERS

         Sales to foreign customers  represented  approximately 20%, 17% and 12%
of net sales for the 1995,  1994 and 1993 fiscal  years,  respectively.  Foreign
sales may be  subject to  political  and  economic  risks,  including  political
instability, changes in import/export regulations, tariffs and freight rates and
difficulties  in  collecting  receivables  and  enforcing  contracts  generally.
Although the Company has not  experienced  any materially  adverse  effects with
respect to sales to foreign  customers,  changes in current  tariff  structures,
exchange  rates or other trade  policies  could  adversely  affect the Company's
sales to foreign customers or the collection of receivables  generated from such
sales.


ORDER BACKLOG

         The Company's  consolidated order backlog at October 1, 1995 (primarily
for delivery  within nine months) was  $62,700,000 as compared to $47,600,000 at
October 2, 1994.  Although  total  backlog has  increased by 32%, the mix of new
orders  reflects a flat demand in military  related  business and an increase in
commercial, industrial, medical and space business. See discussion of changes in
military  procurement  practices  in  Management's  Discussion  and  Analysis of
Financial Condition and Results of Operations.

         Lead  times  for  the  release  of  purchase  orders  depend  upon  the
scheduling  practices of  individual  customers.  The  delivery  times of new or
non-standard   products  can  be  affected  by  scheduling   factors  and  other
manufacturing   considerations.   The  rate  of  booking  new  orders  can  vary
significantly  from  month to  month.  For these  reasons,  and  because  of the
possibility  of  customer  changes in delivery  schedules  or  cancellations  of
orders,   the  Company's   backlog  as  of  any  particular   date  may  not  be
representative of actual sales for any succeeding period.

         A portion of the Company's sales are to military and aerospace  markets
which are subject to the business risk of changes in governmental appropriations
and changes in national  defense  policies and  priorities.  See  discussion  of
changes  in  military  procurement  practices  in  Management's  Discussion  and
Analysis of Financial Condition and Results of Operations.  All of the Company's
contracts with prime U.S. Government's  contractors contain customary provisions
permitting  termination at any time at the convenience of the U.S. Government or
the prime  contractor  upon  payment to the  Company for costs  incurred  plus a
reasonable profit.  Certain contracts are also subject to price renegotiation in
accordance with U.S. Government sole source procurement







provisions.  No material contract of the Company has been terminated or
renegotiated.

COMPETITION

         The Company competes  primarily in the discrete  semiconductor  market,
particularly  in the  area of  high  reliability  components.  The  Company  has
numerous  competitors  across all of its product  lines.  In the defense  market
sector,   the  Company   possesses  the  major  share  of  the  market.  In  the
commercial/industrial  arena,  there are numerous  competitors such as Motorola,
Inc., General  Instruments  Corp., ITT Corp. and National  Semiconductor who are
significantly  larger than Microsemi and have greater resources.  Competition in
certain of its product lines is dependent on price and performance.  Competition
in the high  reliability  area is  dependent  less on price and more on  product
reliability and performance.  The Company believes that it competes  effectively
in all areas of business in which it is engaged.


CHANGES IN TECHNOLOGY

         The power semiconductor  market is subject to technological  change and
changes in industry standards. To remain competitive,  the Company must continue
to devote  resources  to  advance  process  technologies,  to  increase  product
performance,  to improve manufacturing yields and to improve the mix between the
Company's  shipment of military and commercial product and between its high cost
and low cost products.  There can be no assurance that the Company's competitors
will not develop new technologies that are substantially  equivalent or superior
to the Company's technology.


PROPRIETARY RIGHTS

          The Company  generally does not have, nor does it generally  intend to
apply for,  patent  protection  on any  aspect of its  technology.  The  Company
believes that patents often provide only narrow  protection and patents  require
public  disclosure of information which may otherwise be subject to trade secret
protection.  The Company's reliance upon protection of some of its technology as
"trade secrets" will not  necessarily  protect the Company from the use by other
persons  of its  technology,  or their  use of  technology  that is  similar  or
superior to that which is embodied in the Company's trade secrets.  There can be
no assurance that others will not be able to  independently  duplicate or exceed
the Company's technology in whole or in part. No assurances can be made that the
Company  will  be  able  to  maintain  the   confidentiality  of  the  Company's
technology,  dissemination  of which could have a material adverse effect on the
Company's  business.  In addition,  litigation may be necessary to determine the
scope and validity of the Company's  proprietary  rights.  In instances in which
the Company  holds any patents on a product  line,  the patents are not known to
have any material current value. Also there can be no assurance that any patents
held by the Company will not be challenged, invalidated or circumvented, or that
the  rights  granted  thereunder  will  provide  competitive  advantages  to the
Company.


MANUFACTURING RISKS

         The  Company's  manufacturing  processes  are highly  complex,  require
advanced and costly equipment and are  continuously  being modified in an effort
to  improve  yields  and  product   performance.   Minute  impurities  or  other
difficulties  in the  manufacturing  process  can  lower  yields.  In  addition,
California and the Pacific Rim are known to contain various  earthquake  faults.
The Company's operations could be materially adversely affected if production at







any of its major facilities were interrupted.  There can be no assurance that
the Company will not experience manufacturing difficulties in the future.



DEPENDENCE ON KEY PERSONNEL

         The Company's  future  performance  is  significantly  dependent on the
continued active participation of members of its current management. The Company
does not have written  employment  contracts with its  employees.  Should one or
more of the  Company's  key  management  employees  leave  or  otherwise  become
unavailable to the Company, the Company's business and results of operations may
be materially adversely affected.


POSSIBLE VOLATILITY OF STOCK PRICES

         The  market  prices  of  securities  issued  by  technology  companies,
including the Company,  have been volatile.  The  securities of many  technology
companies have  experienced  extreme price and volume  fluctuations,  which have
often  been not  necessarily  related  to the  companies'  respective  operating
performances.  Quarter to quarter  variations in operating  results,  changes in
earnings  estimates by analysts,  announcements of technological  innovations or
new products,  announcements  of major contract  awards,  events involving other
companies in the  industry  and other  events or factors may have a  significant
impact on the market price of the Company's Common Stock.

PRODUCT LIABILITY

         The Company's business exposes it to potential liability risks that are
inherent in the  manufacturing  and  marketing  of  high-reliability  electronic
components  for  critical  applications.  No  assurances  can be made  that  the
Company's  product  liability  insurance  coverage is  adequate or that  present
coverage will continue to be available at  acceptable  costs,  or that a product
liability claim would not adversely  affect the business or financial  condition
of the Company.


CHANGE OF CONTROL PROVISIONS

         The Company's Certificate of Incorporation,  Bylaws, Shareholder Rights
Plan and certain  employment  compensation plans contain provisions that make it
more  difficult  for a third party to acquire,  or that may  discourage  a third
party from  attempting  to acquire,  control of the Company.  In addition,  as a
Delaware  corporation,  the Company is subject to the restrictions imposed under
Section 203 of the Delaware  General  Corporation  Law which prevent the Company
from  engaging in certain  change of control  transactions  with  certain of its
stockholders under certain circumstances.


ENVIRONMENTAL REGULATION

         While  the  Company  believes  that  it has the  environmental  permits
necessary  to conduct its business  and that its  activities  conform to present
environmental  regulations,  increased  public attention has been focused on the
environmental impact of semiconductor operations. The Company, in the conduct of
its  manufacturing  operations,  has handled and does handle  materials that are
considered hazardous, toxic or volatile under federal, state and local laws and,
therefore, is subject to regulations relating to their use,








storage,  discharge  and disposal.  No  assurances  can be made that the risk of
accidental release of such materials can be completely eliminated.  In addition,
the Company  operates or owns  facilities  located on or near real property that
may formerly have been used in ways that involved such  materials.  In the event
of a violation  of  environmental  laws,  the  Company  could be held liable for
damages  and  the  costs  of  remediation,  and,  along  with  the  rest  of the
semiconductor industry, is subject to variable  interpretations and governmental
priorities concerning environmental laws and regulations. Environmental statutes
have been  interpreted  to provide  for joint and several  liability  and strict
liability regardless of actual fault. There can be no assurance that the Company
and its subsidiaries will not be required to incur costs to comply with, or that
the  operations,  business,  or  financial  condition of the Company will not be
materially  adversely  affected  by,  current  or future  environmental  laws or
regulations.
