During the first quarter of fiscal year 2001, the Company changed its method of
determining the cost of inventories at its Scottsdale subsidiary ("Scottsdale")
from the last-in, first-out ("LIFO") method to the first-in, first-out ("FIFO")
method.  The Company believes that the FIFO method is preferable since it will
enhance the comparability of the Company's financial statements by changing to
the predominant method utilized in its industry and will conform all inventories
of the Company to the same accounting method.  In addition, Scottsdale has
experienced improvements in productivity and permanent declines in inventory
costs.  Accordingly, the FIFO method will result in a better matching of
revenues and costs and measurement of operating results. The Company has also
applied to the Internal Revenue Service to change to the FIFO inventory costing
method for income tax purposes.

As required by Accounting Principles Board Opinion No. 20, Accounting Changes,
all previously reported results have been restated to reflect the retroactive
application of this accounting change as of the beginning of fiscal year 2000.
The effect of the restatement was to increase retained earnings at October 1,
2000 by $39,000. The respective effects on net income for the three-month and
nine-month periods ended July 2, 2000 were immaterial.

3.  CONTINGENCY

In Broomfield, Colorado, the owner of a property located adjacent to a
manufacturing facility owned by a subsidiary of the Company had notified the
subsidiary and other parties, claiming that contaminants migrated to his
property, thereby diminishing its value.  In August 1995, the subsidiary,
together with former owners of the manufacturing facility, agreed to settle the
claim and to indemnify that owner of the adjacent property for remediation
costs.  Although TCE and other contaminants previously used at the facility are
present in soil and groundwater on the subsidiary's property, the Company
vigorously contests any assertion that the subsidiary is the cause of the
contamination.  In November 1998, the Company signed an agreement with three
former owners of this facility whereby the former owners 1) reimbursed the
Company for $530,000 of past costs, 2) assumed responsibility for 90% of all
future clean-up costs, and 3) agreed to indemnify and protect the Company
against any and all third-party claims relating to the contamination of the
facility.  An Integrated Corrective Action Plan has been submitted to the State
of Colorado.  State and local agencies in Colorado are reviewing current data
and considering study and cleanup options, and it is not yet possible to predict
costs for remediation.  In the opinion of management, the final outcome of the
Broomfield, Colorado environmental matter will not have a material adverse
effect on the Company's financial position, results of operations or cash flows.

The Company is involved in various pending litigation matters, arising out of
the normal conduct of its business, including from time to time litigation
relating to commercial transactions, contracts, and environmental matters.  In
the opinion of management, the final outcome of these matters will not have a
material adverse effect on the Company's financial position, results of
operations or cash flows.

4.  COMPREHENSIVE INCOME

Comprehensive income is defined as the change in equity (net assets) of a
business enterprise during the period from transactions and other events and
circumstances from non-owner sources.  Accumulated other comprehensive loss
consists of the change in the cumulative translation adjustment.  Total
comprehensive income of the Company for the quarters ended July 2, 2000
(Restated-Note 2) and July 1, 2001 was $2,793,000 and $4,442,000, respectively.
Total comprehensive income for the nine months ended July 2, 2000 (Restated-Note
2) and July 1, 2001 was $3,962,000 and $12,781,000, respectively.

5.  EARNINGS PER SHARE

Basic earnings per share have been computed based upon the weighted average
number of common shares outstanding during the respective periods.  Diluted
earnings per share have been computed, when the result is dilutive, using the
treasury stock method for stock options outstanding and giving effect to
issuance of shares upon conversion of debt during the respective periods.

Earnings per share for the respective quarters and respective nine months ended
July 2, 2000 and July 1, 2001 were calculated as follows:

6.  RECENTLY ISSUED ACCOUNTING STANDARDS

In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS No.
133, "Accounting for Derivative Instruments and Hedging Activities," which
established new standards for derivative instruments, including certain
derivative instruments embedded in other contracts, and for hedging activities.
The Company adopted SFAS No. 133 in fiscal year 2001; however, the adoption of
this standard did not have any material impact on the consolidated results of
operations, financial position or cash flows of the Company.

In June 2001, the FASB issued SFAS No. 141, "Business Combinations" and SFAS No.
142, "Goodwill and Other Intangible Assets."  SFAS No. 141 establishes new
accounting and reporting standards for business combinations and will require
that the purchase method of accounting be used for all business combinations
initiated after June 30, 2001 and for all business combinations accounted for by
the purchase method for which the date of acquisition is after June 30, 2001.
Use of the pooling-of-interest method will be prohibited.  SFAS No. 142, which
changes the accounting for goodwill from an amortization method to an
impairment-only approach, will be effective no later than the first quarter of
fiscal year 2003.  The Company is currently evaluating the impact of adopting
SFAS No. 141 and No. 142.

7.    SEGMENT INFORMATION

The Company's reportable operating segments are based on geographic location,
and the measure of segment profit is income from operations.

The Company operates predominantly in a single industry segment as a
manufacturer of discrete semiconductors and whole-circuit solutions.  Geographic
areas in which the Company operates include the United States, Europe and Asia.
Intergeographic sales primarily represent intercompany sales which are accounted
for based on established sales prices between the related companies and are
eliminated in consolidation.

Financial information by geographic segments is as follows:

8.    SUBSEQUENT EVENTS

On June 12, 2001, Microsemi announced that it had entered into an agreement in
principle to acquire the assets of Compensated Devices, Inc. (CDI), of Melrose,
MA.  Microsemi will pay $11.5 million for CDI in a combination of cash and one-
year notes that are payable in cash and/or shares of Microsemi's common stock,
at Microsemi's option and assume certain liabilities. This acquisition is
expected to be completed in the fourth quarter of fiscal year 2001.

On July 31, 2001, Microsemi announced that its stockholders approved the
proposed increase in the number of authorized shares of its Common Stock from 20
million to 100 million pursuant to written consents. Based on this approval, the
board of directors of Microsemi has declared a 2-for-1 stock split to be
effected by a dividend payable in shares of Common Stock. The dividend is
payable August 28, 2001 to stockholders of record as of the close of business on
August 14, 2001. Stockholders will receive one additional share of Common Stock
for every one share held on the record date. As a result of the stock split,
Microsemi's outstanding shares of Common Stock would increase from 14,072,286
(including 1,013 treasury shares), to 28,144,572 shares, estimated based upon
the currently outstanding shares.

On August 2, 2001, Micro NES Acquisition Corp.("MNES"), a wholly-owned
subsidiary of Microsemi and New England Semiconductor Corp. and a wholly-owned
subsidiary thereof ("NESC") consummated a purchase and sale of assets. MNES
plans to operate the acquired business or assets at the same physical location
in Lawrence, Massachusetts where the seller has operated them prior to August 2,
2001. MNES has paid approximately $3.3 million cash to the seller, approximately
$6 million was paid with a one-year promissory note and the balance of
approximately $5 million was mostly paid in the form of cash or assumed loans
and other obligations specified in the agreement. The parties arrived at the
price and terms on the basis of negotiations which resulted in a letter of
intent signed and announced by Microsemi in early June 2001. MNES paid for the
acquisition with a loan from Microsemi. NESC and its shareholders previously had
no material relationship with Microsemi, its directors or officers, or their
respective associates. Another subsidiary of Microsemi had been a sublessor to
New England Semiconductor Corp., and that sublease was terminated as part of
this transaction.

INTRODUCTION
- ------------

Microsemi Corporation is a leading designer, manufacturer and marketer of
analog, mixed-signal and discrete semiconductors.  The Company's semiconductors
manage and regulate power, protect against transient voltage spikes and
transmit, receive and amplify signals.  Microsemi's products include individual
components as well as whole-circuit solutions that enhance customer end products
by providing battery optimization, reducing size or protecting circuits.
Microsemi's commercial products are used in dynamic high growth mobile
connectivity applications, including mobile phones and handheld Internet
devices, and broadband communications applications such as base stations,
wireless LAN, and cable and fiber optic systems. These high growth opportunities
have emerged from ongoing capabilities in designing and manufacturing
semiconductors for military, satellite and medical applications.  The Company
serves several end markets of the semiconductor industry. These end markets
include battery-operated products, communications and Internet infrastructure,
and military and aerospace. Battery-operated products include portable digital
assistants (PDAs), mobile phones, portable or implantable medical equipment,
hearing aids, notebook computers and wireless web tablets.  The Company's
diverse customer base includes Motorola, Lockheed Martin, Seagate, Mitsubishi,
Guidant, Samsung, Medtronic, Boeing, Palm, Dell and Compaq.

Results Of Operations For The Quarter Ended July 2, 2000 (Restated-Note 2)
Compared To The Quarter Ended July 1, 2001.

Net sales decreased $6.5 million, from $66.6 million for the third quarter of
fiscal year 2000 to $60.1 million for the third quarter of fiscal year 2001.
The decrease was primarily attributable to a decline in products sold to the
low-end PC and mobile telephone markets and by the reduction or elimination of
revenues generated by subsidiaries that were sold or closed, partially offset by
higher sales of power management, TVS and RF/Microwave products to the mobile
connectivity and telecommunications markets, as well as increased sales to the
military and space/satellite customers. The Company sold the assets of its Micro
Commercial Components division ("MCC") and closed this division in June 2000.
The Company also discontinued the operations of BKC Semiconductors, Inc. ("BKC")
in September 2000 and Microsemi (H.K.) Ltd. ("Hong Kong") in June 2001. For the
quarter ended July 2, 2000, MCC, BKC and Hong Kong had revenues of $2.5 million,
$2.0 million and $1.0 million, respectively. For the quarter ended July 1, 2001,
Hong Kong had revenues of $0.6 million.

Gross profit increased $1.4 million, from $19.1 million for the third quarter of
fiscal year 2000 to $20.5 million for the third quarter of fiscal year 2001.  As
a percentage of sales, gross profit was 28.6% for the third quarter of fiscal
year 2000, compared to 34.1% for the third quarter of fiscal year 2001.  This
increase was due primarily to higher capacity utilization, a shift in revenues
from lower-margin commodity products in the computer/peripherals and industrial
markets to higher-margin application-specific products in the mobile
connectivity, telecommunications, medical and commercial satellite markets,
which is expected to continue for the remainder of the year, and the
consolidation of certain operations that produced lower margin products.  MCC,
BKC and Hong Kong had gross profit of $0.0 million, $1.0 million and $0.2
million in the quarter ended July 2, 2000. Hong Kong had a gross profit of $0.2
in the quarter ended July 1, 2001.

Selling, general and administrative expenses decreased from $10.3 million for
the third quarter of fiscal year 2000 to $9.5 million for the third quarter of
fiscal year 2001, primarily due to eliminations of expenditures of the
businesses that were sold or closed.

                                       12


Research and development expense increased $1.1 million, from $3.0 million for
third quarter of fiscal year 2000 to $4.1 million for the third quarter of
fiscal year 2001.  The increase was primarily due to higher spending to develop
power management and RF/Microwave products for the mobile connectivity,
telecommunications and medical markets.

The effective income tax rate was 33.0% in the quarters ended July 2, 2000 and
July 1, 2001, respectively.

Results Of Operations For The Nine Months Ended July 2, 2000 (Restated-Note 2)
Compared To The Nine Months Ended July 1, 2001.

Net sales increased $4.0 million, from $182.2 million for the first nine months
of fiscal year 2000 to $186.2 million for the first nine months of fiscal year
2001.  The increase was primarily attributable to higher sales of power
management, TVS and RF/Microwave products to the mobile connectivity and
telecommunications markets, as well as sales to the military and space/satellite
customers, partially offset by a decline in products sold to the low-end PC and
mobile telephone markets, partially offset by revenues generated by divisions
that were sold or closed.  The Company sold the assets of its MCC division and
closed this division in June 2000. The Company also discontinued the operations
of BKC in September 2000, Microsemi PPC Inc. ("PPC") in March 2001 and Hong Kong
in June 2001. For the nine months ended July 2, 2000, MCC, BKC, PPC and Hong
Kong had revenues of $9.8 million, $6.3 million, $3.2 million and $2.7 million,
respectively. For the nine months ended July 1, 2001, PPC and Hong Kong had
revenues of $2.8 million and $2.4 million, respectively.

Gross profit increased $11.2 million, from $49.8 million for the first nine
months of fiscal year 2000 to $61.0 million for the first nine months of fiscal
year 2001.  As a percentage of sales, gross profit was 27.3% for first nine
months of fiscal year 2000, compared to 32.8% for the corresponding period of
fiscal year 2001.  This increase was due primarily to higher capacity
utilization and a shift in revenues from lower-margin commodity products in the
computer/peripherals and industrial markets to higher-margin application-
specific products in the mobile connectivity, telecommunications, medical and
commercial satellite markets, and the closures of certain operations that
produced lower-margin products.  MCC, BKC, PPC and Hong Kong had gross profit of
$1.0 million, $3.2 million, $0.0 million and $0.3 million in the first nine
months of fiscal year 2000. PPC and Hong Kong had gross profit of $1.0 million
and $0.7 million in the first nine months of fiscal year 2001.

Selling, general and administrative expenses increased $0.9 million from $28.4
million for the first nine months of fiscal year 2000 to $29.3 million for the
first nine months of fiscal year 2001, primarily due to increased expenditures
to support the increase in sales, partially offset by the elimination and
reduction of expenses incurred by the subsidiaries that were sold or closed.

Research and development expense increased $3.3 million, from $8.0 million for
the first nine months of fiscal year 2000 to $11.3 million for the first nine
months of fiscal year 2001.  The increase was primarily due to higher spending
on development of power management and RF/Microwave products for the mobile
connectivity, telecommunications and medical markets.

The effective income tax rate was 33.0% in the nine months ended July 2, 2000
and July 1, 2001, respectively.


Capital Resources And Liquidity

Net cash provided by operating activities was $27.7 million and $15.2 million
for the first nine months of fiscal years 2000 and 2001, respectively.  The net
cash provided by operating activities was $12.4 million less in the first nine
months of fiscal year 2001 than had been provided in the same period of fiscal
year 2000 as a result of the combined impact of greater net income during the
first nine months of fiscal year 2001, more than offset by the combined effect
of differences in certain non-cash financial statement items, such as the
provision for returns and doubtful accounts, acquired in-process research and
development, accounts receivable, inventories, other current assets,  accrued
liabilities and taxes.

                                       13


Net cash used in investing activities was $7.5 million and $9.4 million for the
nine months ended July 2, 2000 and July 1, 2001, respectively. The net cash used
in investing activities was $1.9 million more in the first nine months of fiscal
year 2001 than it had been in the first nine months of fiscal year 2000,
primarily due to a higher amount of purchases of property and equipment in the
first nine months of fiscal year 2001.

Net cash (used in) provided by financing activities was ($2.5) million and $1.1
million for the first nine months of fiscal years 2000 and 2001, respectively.
In the first nine months of fiscal year 2000 the Company repaid a large portion
of the Company's debt with proceeds from sales of its common stock and from
exercises of employee stock options. The net cash provided from financing in the
first nine months of fiscal year 2001 was primarily a combined result of
proceeds from exercises of employee stock options, partially offset by repayment
of a smaller portion of the Company's debt.

Microsemi's operations in the nine months ended July 1, 2001 were funded with
internally generated funds.  The Company has maintained a credit line with a
bank, from which it can borrow up to $30 million.  The credit line is secured by
substantially all of the assets of the Company.  This credit line expires in
March 2003.  As of July 1, 2001, there were no funds borrowed under this credit
facility.  The credit line includes a facility to issue letters of credit, and
$4.1 million was outstanding in the form of letters of credit as of July 1,
2001.  At July 1, 2001, Microsemi had $37.4 million in cash and cash
equivalents.

Based upon information currently available, management believes that Microsemi
can meet its current operating cash and debt service requirements with
internally generated funds together with its available borrowings.

IMPORTANT FACTORS RELATED TO FORWARD-LOOKING STATEMENTS AND ASSOCIATED RISKS
- ----------------------------------------------------------------------------


Some of the statements in this report or incorporated by reference are forward-
looking, including, without limitation, the statements under the captions
"Management's Discussion and Analysis of Financial Condition and Results of
Operations".  These statements include those that contain words like "may,"
"will," "could," "should," "project," "believe," "anticipate," "expect," "plan,"
"estimate," "forecast," "potential," "intend," "maintain,"  "continue" and
variations of these words or comparable words.  In addition, all of the non-
historical information herein is forward-looking, include any statement or
implication about a future time, result or other circumstance. Forward-looking
statements are not a guarantee of future performance and involve risks and
uncertainties.  Actual results may differ substantially from the results that
the forward-looking statements suggest for various reasons. These forward-
looking statements are made only as of the date of this report. Microsemi does
not undertake to update or revise the forward-looking statements, whether as a
result of new information, future events or otherwise.

The forward-looking statements included in this report are based on, among other
items, current assumptions that Microsemi will be able to meet its current
operating cash and debt service requirements, that Microsemi will be able to
successfully resolve disputes and other business matters as anticipated, that
competitive conditions within the analog, mixed signal and discrete
semiconductor, integrated circuit or custom component assembly industries will
not affect the Company materially or adversely, that Microsemi will retain
existing key personnel, that Microsemi's forecasts will reasonably anticipate
market demand for its products, and that there will be no other material adverse
change in its operations or business. Other factors that could cause results to
vary materially from current expectations are referred to elsewhere in this
report. Assumptions relating to the foregoing involve judgments that are
difficult to make and future circumstances that are difficult to predict
accurately or correctly. Forecasting and other management decisions are
subjective in many respects and thus susceptible to interpretations and periodic
revisions based on actual experience and business developments, the impact of
which may cause Microsemi to alter its internal forecasts, which may in turn
affect results or expectations.  Microsemi Corporation does not undertake to
announce publicly these changes that may occur in our expectations after the
periods presented herein.  Readers are cautioned against giving undue weight to
any of the forward-looking statements.

Adverse changes to our results could result from any number of factors,
including for example fluctuations in economic conditions, potential effects of
inflation, lack of earnings visibility, dependence upon certain customers or
markets, dependence upon suppliers, future capital needs, rapid technological
changes, difficulties in integrating acquired businesses, ability to realize
cost savings or productivity gains, potential cost increases, dependence on key
personnel, difficulties regarding hiring and retaining qualified personnel in a
competitive labor market, risks of doing business in international markets, and
problems of third parties.

The inclusion of forward-looking information should not be regarded as a
representation by Microsemi or any other person that its objectives or plans
will be achieved.  Additional factors that could cause results to vary
materially from current expectations are discussed under the heading "Important
factors related to forward-looking statements and associated risks" in the
annual report in the Form 10-K as filed with the Securities and Exchange
Commission in December 2000, and elsewhere in that Form 10-K, including but not
limited to, under the headings, "Legal Proceedings," "Management's Discussion
and Analysis of Financial Condition and Results of Operations," and the notes to
the financial statements included therein.
