PART 1

ITEM 1. BUSINESS

OVERVIEW

Plexus Corp. and its subsidiaries (together "Plexus," the "Company," or
"we") provide product realization services to original equipment manufacturers,
or OEMs, in the networking/datacommunications, medical, industrial, computer and
transportation industries. We provide advanced electronics design, manufacturing
and testing services to our customers and focus on complex, high-end products.
We offer our customers the ability to outsource all stages of product
realization, including: development and design, materials procurement and
management, prototyping and new product introduction, testing, manufacturing and
after-market support.

We believe that our broad service offerings with respect to the design
and realization of complex, high-end products within the electronics
manufacturing services, or EMS, industry provide us with a significant
competitive advantage. Through a staff of over 440 product development
engineers, we offer a complete menu of engineering services, including digital
and analog design, mechanical and industrial design, embedded software design,
printed circuit board design, test equipment and software development, product
verification and new product introduction services. Our manufacturing services
include printed circuit board assembly, product configuration, testing, final
product and system box build and after-market support. Throughout the production
process, we offer logistics services, such as materials procurement, inventory
management, packaging and distribution.

Our customers include both industry-leading OEMs and emerging
technology companies. Due to our focus on serving OEMs in high-growth technology
and medical sectors, our business is influenced by major technological trends
such as the level and rate of development of fiber optics and RF/wireless
infrastructure, the expansion of network computing and Internet use, and the
expansion of outsourcing by OEMs generally.

Established in 1979, we have approximately 5,600 full-time employees
and 25 facilities in 18 locations, totaling approximately 1.6 million square
feet. Over the past few years, we have expanded our capacity and geographic
reach through a series of strategic acquisitions. Through these transactions, we
have enhanced our access to, and ability to provide services within, important
technology corridors in Boston, Chicago, San Diego and Seattle; established a
base in Europe; significantly increased the size and capabilities of our medical
services offerings; significantly expanded our capacity with respect to the
assembly of configured-to-order wireless products and printed circuit board
("PCB") design services; and acquired proven low-cost manufacturing operations
in Mexico. A pending acquisition will provide facilities in China, Malaysia and
additional United States locations.


2
SERVICES

Plexus offers a broad range of integrated services that provide
customers with a total design, new product introduction and manufacturing
solution to take a product from initial design through production to
after-market support. Our customers may utilize any or all of the following
services and tend to use more of these services as their outsourcing strategies
mature:

Product development and design. We provide comprehensive product
development and design and test engineering services. These services include
project management, initial feasibility studies, product concept definition,
specifications for product features and functions, product engineering
specifications, microprocessor selection, circuit design, software design,
application-specific integrated circuit design, printed circuit board layout,
product housing design, development of test specifications and product
validation testing. Through our product development and design services, we
provide customers with a complete product design that can be manufactured
efficiently.

Prototyping and new product introduction services. We provide rapid
assembly of prototype products within our dedicated, streamlined New Product
Introduction Plus centers. We supplement our prototype assembly services with
value-added services, including printed circuit board design, materials
management, manufacturing defects analysis, analysis of the manufacturability
and testability of a design, test implementation and pilot production runs
leading to volume production. These services link our engineering organization,
our customers' engineering organizations and our volume manufacturing
organization. This link facilitates an efficient transition to manufacturing. We
believe that these services provide significant value to our customers by
accelerating their products' time-to-market schedule.

Test development and product testing. Because product functionality has
driven components and assembly techniques to become increasingly complex, there
is a need to design and assemble increasingly complex in-circuit and functional
test equipment for electronic products and assemblies. Our internal development
of this test equipment allows us to rapidly implement test solutions and
efficiently test printed circuit assemblies, subassemblies and product and
system assemblies. We also develop and utilize specialized equipment that allows
us to environmentally stress-test products during functional testing to assure
reliability. We believe that the design and production of test equipment is an
important factor in our ability to provide technology-driven products of
consistent and high quality.

Manufacturing and assembly. We provide turnkey manufacturing services
for a variety of electronic products to diverse industries. These services
include developing and implementing a materials strategy that meets customers'
demand and flexibility requirements, assembling printed circuit assemblies
utilizing a wide range of assembly technologies, building and configuring final
product and system boxes and testing assemblies to meet customers' requirements.
We have the expertise to assemble very complex electronic products that utilize
multiple printed circuit boards and subassemblies. These complex products are
typically configured to fulfill unique customer requirements and many are
shipped directly to our customers' end users. In addition, we have developed
special processes and tools to meet industry-specific requirements. Among these
are the tools and processes to assemble finished medical devices that meet U.S.
Food and Drug Administration Quality Systems Regulation requirements and similar
regulatory requirements of other countries.

After-market support. We provide service support for manufactured
products. In this context, supported products, which may or may not be under the
customer's warranty, may be returned for repairs or upgrades at the customer's
discretion.

RECENT AND PENDING COMBINATIONS AND ACQUISITIONS

Since fiscal 1998, we have completed eight acquisitions that have added
facilities totaling approximately 735,000 square feet and over 2,800 new
employees. We have actively pursued combinations and acquisitions to expand our
geographic reach, increase our design, engineering and manufacturing capability
and breadth of service offerings and strengthen and broaden our customer
relationships. Since fiscal 1998, we have completed the following acquisitions
(information is as of the respective acquisition dates):

In addition, the Company has recently announced its pending acquisition
of certain assets of MCMS, Inc. ("MCMS"), an EMS provider to OEMs for
approximately $45 million, subject to purchase price adjustments. The assets to
be purchased from MCMS, which is in Chapter 11 bankruptcy proceedings, include
facilities located in Penang, Malaysia; Xiamen, China; Nampa, Idaho; and
Raleigh, North Carolina. MCMS' Monterrey Mexico and Colfontaine, Belgium
operations will not be included in the transaction. The acquisition does not
include any interest-bearing debt, but does include the assumption of certain
specific liabilities. Upon completion of this transaction, the Company will
establish its initial manufacturing presence in Asia. The acquisition will be
recorded utilizing the accounting principles promulgated by Statement of
Financial Accounting Standards ("SFAS") No's. 141 and 142 (See Note 1 in the
Notes to Consolidated Financial Statements). The transaction is expected to
close in January and is subject to clearance under the federal Hart-Scott-Rodino
Act ("HSR") and other closing conditions.

CUSTOMERS AND INDUSTRIES SERVED

We provide services to a wide variety of customers, ranging from large
multinational companies to smaller emerging technology companies, including
start-ups. During fiscal 2001, we provided services to approximately 200
customers (includes PCB design only customers). Because of the variety of
services we offer, our flexibility in design and manufacturing and our ability
to respond to customer needs in a timely fashion, we believe that we are well
positioned to offer our services to customers in most market segments. For many
customers, we serve both a design and production function, thereby permitting
customers to concentrate on concept development, distribution and marketing,
while accelerating their time to market, reducing their investment in
manufacturing capacity and optimizing total product cost.

4
No customer represented more than 10% of sales in fiscal 2001. Lucent
Technologies Inc. ("Lucent") and General Electric Company ("GE") represented
over 10 percent of our net sales for the periods set forth below:

*represents sales less than 10 percent

Many of our large customers contract independently through multiple
divisions, subsidiaries, production facilities or locations. We believe that in
most cases our sales to one such subsidiary, division, facility or location are
not dependent on sales to others. Although the complete loss of any major
customer could have a significant negative impact on us, we do not believe the
loss of all divisions, subsidiaries, facilities or locations of a major customer
to be likely.

We provided services within the following industries in the following
proportions:

</TABLE>

MATERIALS AND SUPPLIERS

We purchase raw materials and electronic components from manufacturers
and distribution companies. The key electronic components we purchase include
printed circuit boards, specialized components such as application-specific
integrated circuits, semiconductors, interconnect products, electronic
subassemblies (including memory modules, power supply modules and cable and wire
harnesses), resistors and capacitors. Along with these electronic components, we
also purchase components for use in higher-level assembly and manufacturing.
These components include sheet metal fabrications, aluminum extrusions, die
castings and various other hardware and fastener components. These components
range from standard to highly customized and they vary widely in terms of market
volatility and price.

From time to time, allocation of components becomes an integral part of
the electronics industry, and component shortages can occur with respect to
particular components. In response, we actively manage our business in a way
that minimizes our exposure to materials and component shortages. We have
developed a corporate procurement organization whose primary purpose is to
create strong supplier alliances to ensure, as much as possible, a steady flow
of components at competitive prices. Because we design products and can
influence what components are used in some new products, components
manufacturers often provide us with a greater amount of materials and
components, even during shortages. We have also established and continue to
expand strategic relationships with international purchasing offices, and we
attempt to leverage our design position with suppliers. Beyond this, we have
undertaken a series of flexibility initiatives, including the utilization of
in-plant stores, point-of-use programs, assured supply programs and similar
efforts. All of these undertakings seek to improve our overall supply chain
flexibility and to accommodate our growth plans.

SALES AND MARKETING

We market our services primarily through our sales and marketing
organization of approximately 65 people, which includes salespeople, strategic
customer managers, technology specialists and advertising and other


5
corporate communications personnel. Our sales and marketing efforts focus on
generating new customers and pursuing profitable opportunities. We use our
ability to provide a full range of product realization services as a marketing
tool, and our technology specialists participate in marketing through direct
customer contact and participation in industry symposia and seminars. Our sales
force is integrated with the rest of our business and is aligned geographically
within important technology corridors. We support our sales and marketing
efforts with in-depth industry research.

COMPETITION

The market for the products and services we provide is highly
competitive. We compete primarily on the basis of engineering, testing and
production capabilities, technological capabilities and the capacity for
responsiveness, quality and price. There are many competitors in the electronics
design and assembly industry. Larger and more geographically diverse competitors
have substantially more resources than we do. Other, smaller competitors compete
only in narrow, specific areas of our business. We also compete against
companies that design or manufacture items in-house rather than by outsourcing.
In addition, we compete against foreign, low-labor-cost manufacturers. This
foreign, low-labor-cost competition tends to focus on commodity and
consumer-related products, which is not our primary focus.

INTELLECTUAL PROPERTY

The Company does not own any material patents or copyrights. The
Company owns various servicemarks, including "Plexus," and "Plexus, The Product
Realization Company."

The Company (along with many other companies) has been sued by
the Lemelson Medical, Education & Research Foundation Limited Partnership
("Lemelson") related to the alleged possible infringement of certain Lemelson
patents relating to machine vision and bar-code technology. The Company had
requested a stay of the action pending developments in other Lemelson
litigation, which has been granted. If a judgment is rendered and/or a license
fee required, it is the opinion of management of the Company that such judgment
would not be material to the consolidated financial position of the Company or
the results of its operations.

To augment its management information systems, in the first quarter of
fiscal 2001, the Company entered into a license agreement with JD Edwards for
enterprise resource planning ("ERP") software and systems to enhance and
standardize the Company's ability to translate information from production
facilities into financial and managerial reporting. The conversion timetable
remains subject to change; however, the Company has begun developing its global
model and completed a pilot conversion. The conversion process is expected to
continue for at least three years to convert all current sites and business
units.

ENVIRONMENTAL COMPLIANCE

The Company is subject to a variety of environmental regulations
relating to the use, storage, discharge and disposal of hazardous chemicals used
during its manufacturing process. Although the Company believes that it is in
compliance with all federal, state and local environmental laws, and does not
anticipate any significant expenditures in maintaining its compliance, there can
be no assurances that violations will not occur which could have a material
adverse effect on the results of the Company.

EMPLOYEES

Our employees are one of our primary strengths, and we make
considerable efforts to maintain a well-qualified staff. We have been able to
offer enhanced career opportunities to many of our employees. Our human
resources department identifies career objectives and monitors specific skill
development for employees with management and technical potential for
advancement. We invest heavily in training at all levels to ensure that
employees are well trained. We operate a policy of involvement and consultation
with employees in every facility and strive for continuous improvement at all
levels.

As of December 1, 2001, we employed approximately 5,600 full-time
employees. Given the quick response time required by our customers, we seek to
maintain flexibility to scale our operations as necessary to


6
maximize efficiency. To do so, we use skilled temporary labor. In Europe,
approximately 40 of our employees are covered by union agreements. These union
agreements are typically renewed at the beginning of each year, although in a
few cases these agreements may last two or more years. None of our employees in
the United States and Mexico is covered by union agreements. We have no history
of labor disputes at any of our facilities. We believe that our employee
relationships are good.

ITEM 2. PROPERTIES

Our facilities comprise an integrated network of technology and
manufacturing centers, with corporate headquarters located in our engineering
facility in Neenah, Wisconsin. We own or lease facilities with approximately 1.6
million square feet of capacity. This includes approximately 1.1 million square
feet in the United States, approximately 250,000 square feet in Mexico and
approximately 102,000 square feet in Europe. We are also undertaking expansion
projects to expand significantly several of our existing facilities. The
geographic diversity of our technology and manufacturing centers allows us to
offer services from locations near our customers and major electronics markets.
We believe that this approach reduces material and transportation costs,
simplifies logistics and communications and improves inventory management. This
enables us to provide customers with a more complete, cost-effective solution.

Our facilities are described in the following table:

(1) As a result of the fiscal 1999 merger with SeaMED Corporation
("SeaMED"), prior historical results have been restated utilizing the
pooling-of-interests method of accounting. Historical results have not
been restated for the fiscal 2001 merger with e2E Corporation ("e2E")
and the fiscal 2000 merger with Agility, Incorporated ("Agility") as
they would not differ materially from reported results. (See Notes 1
and 8 in the Notes to Consolidated Financial Statements.)

(2) In connection with the acquisition of Qtron Inc. ("Qtron") and merger
with e2E and the current economic slowdown, Plexus recorded one-time
merger and acquisition costs of approximately $1.6 million ($1.4
million after-tax) and one-time restructuring costs of approximately
$1.9 million ($1.1 million after-tax). Excluding these charges,
operating income would have been $71.9 million (6.8% of sales), net
income would have been $41.7 million (3.9% of sales) and diluted
earnings per share would have been $0.96.

(3) In connection with the merger with Agility and the acquisitions of
Keltek (Holdings) Limited ("Keltek"), and the turnkey electronics
manufacturing services operations of Elamex, S.A. de C.V. ("Mexico
turnkey operations"), Plexus recorded one-time merger and
acquisition-related charges of $1.1 million ($0.9 million after-tax).
Excluding these charges, operating income would have been $71 million
(9.4% of sales), net income would have been $41.1 million (5.5% of
sales) and diluted earnings per share would have been $1.06.

(4) In connection with the merger with SeaMED, Plexus recorded merger and
other one-time related charges of $7.7 million ($6.0 million
after-tax). Excluding these charges, gross profit would have been $68.6
million (13.9% of sales), and operating income would have been $42.1
million (8.6 % of sales). Net income excluding this charge would have
been $26.3 million (5.3% of sales), and diluted earnings per share
would have been $0.71.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

OVERVIEW

Plexus provides product realization services to original equipment
manufacturers, or OEMs, in the networking/datacommunications, medical,
industrial, computer and transportation industries. We provide advanced
electronics design, manufacturing and testing services to our customers and
focus on complex, high-end products. We offer our customers the ability to
outsource all stages of product realization, including: development and design,
materials procurement and management, prototyping and new product introduction,
testing, manufacturing and after-market support. The following information
should be read in conjunction with our consolidated financial statements
included herein and the "Risk Factors" section beginning on page 15.

We provide contract manufacturing services on either a turnkey basis,
where we procure some or all of the materials required for product assembly, or
on a consignment basis, where the customer supplies some, or occasionally all,
materials necessary for product assembly. Turnkey services include materials
procurement and warehousing in addition to manufacturing and involve greater
resource investment and inventory risk management than consignment services.
Turnkey manufacturing currently represents almost all of our net sales. Turnkey
sales typically generate higher sales and higher gross profit dollars with lower
gross margin percentages than consignment sales due to the inclusion of
component costs, and related markup, in our net sales. However, turnkey
manufacturing involves the risk of inventory management, and a change in
component costs can directly impact average selling prices, gross margins and
our net sales. Due to the nature of turnkey manufacturing, our quarterly and
annual results are affected by the level and timing of customer orders,
fluctuations in materials costs and the degree of automation used in the
assembly process.

MERGERS AND ACQUISITIONS

On May 23, 2001, the Company acquired Qtron, Inc. ("Qtron"), a
privately held EMS provider located in San Diego, California. The Company
purchased all of the outstanding shares of Qtron for approximately $29.0 million
in cash, paid outstanding Qtron notes payable of $3.6 million to Qtron
shareholders and thereby assumed liabilities of $47.4 million, including capital
lease obligations of $18.8 million for a new manufacturing facility. The excess
of the cost over the fair value of the net assets acquired of approximately $24
million has been recorded as goodwill and is being amortized over 15 years. The
purchase price is subject to certain adjustments. The results of Qtron's
operations have been reflected in the Company's financial statements from the
date of acquisition.

On December 21, 2000, the Company merged with e2E Corporation ("e2E"),
a privately held PCB design and engineering service provider for electronic
OEMs, through the issuance of 462,625 shares of its common stock. The
transaction was accounted for as a pooling-of-interests. Costs associated with
this merger in the amount of $1.0 million have been expensed as required. Prior
results were not restated, as they would not differ materially from reported
results.

During fiscal 2000, the Company also acquired operations in
Massachusetts, Mexico and the United Kingdom. (See Note 8 in the Notes to
Consolidated Financial Statements.)

As discussed above, the Company has signed an agreement to acquire a
substantial portion of the assets of MCMS. The transaction is scheduled to be
completed in January 2002, subject to closing conditions. The acquisition would
include the Company's first Asian operations. The MCMS acquisition would be for
a cash purchase price of approximately $45 million, subject to adjustments for
certain working capital items and other adjustments and indemnities provided in
the purchase agreement. The Company expects to finance the purchase through
existing working capital. The acquired operations will be reflected in the
Company's financial information



11
from and after the date of acquisition. Based upon current financial information
from MCMS, the Company expects initial annual sales from the acquired operations
to be in the range of $125 million to $150 million. Because of the relative size
of the acquired operations as compared to the Company, the acquisition and
operations of the MCMS assets and operations may have a material effect on the
Company's financial condition and results going forward.

RESULTS OF OPERATIONS

Net sales. Net sales for the year ended September 30, 2001, increased
41 percent to $1.1 billion from $752 million for the year ended September 30,
2000. Our acquisitions during fiscal 2001 accounted for slightly less than 5
percent of sales for the year ended September 30, 2001. The Company's sales have
been affected by the impact of the overall slow-down in the economy as a whole,
and in particular in the networking/datacommunications infrastructure spend with
some of our customers, resulting in these customers' forecasts and orders
becoming more cautious. These factors will continue to affect fiscal 2002 sales,
and the Company expects first quarter sales to be approximately $200 million.
However, results will ultimately depend on the actual order levels.

Sales for the year ended September 30, 2000, increased 53 percent to
$752 million from $492 million for the year ended September 30, 1999. Sales
growth was impacted by growth in the networking/datacommunications and medical
industries as well as through acquisitions. In addition, acquisitions during
fiscal 2000 accounted for slightly more than 9 percent of sales for that fiscal
year.

The Company had no customers which represented more than 10 percent of
sales for the year ended September 30, 2001 as compared to the prior year, when
Lucent Technologies accounted for 23 percent of the Company's sales for the year
ended September 30, 2000. Lucent Technologies and General Electric accounted for
16 percent and 12 percent of sales, respectively, for the year ended September
30, 1999. Sales to our ten largest customers accounted for 51 percent of sales
for the year ended September 30, 2001, compared to 63 percent and 61 percent for
the years ended September 30, 2000 and 1999, respectively. As with sales to most
of our customers, sales to our largest customers may vary from time to time
depending on the size and timing of customer program commencement, termination,
delays, modifications and transitions. We remain dependent on continued sales to
our significant customers, and we generally do not obtain firm, long-term
purchase commitments from our customers. In addition, we expect an increasing
percentage of our sales will come from emerging technology companies, including
start-ups, mainly in the networking/datacommunications market sector. Customer
forecasts can and do change as a result of their end-market demand and other
factors. Although any material change in orders from these or other customers
could materially affect our results of operations, we are dedicated to
diversifying our customer base and decreasing our dependence on any particular
customer or customers.

Our sales for the years ended September 30, 2001 and 2000,
respectively, by industry were as follows: networking/datacommunications 40
percent (36 percent), medical 22 percent (27 percent), industrial 20 percent (19
percent), computer 10 percent (10 percent) and transportation/other 8 percent (8
percent).

Gross profit. Gross profit for the year ended September 30, 2001,
increased 23 percent to $131.8 million from $107.2 million for the year ended
September 30, 2000. The gross margin for the year ended September 30, 2001, was
12.4 percent, compared to 14.3 percent for the year ended September 30, 2000.

Our gross margins reflect a number of factors that can vary from period
to period, including product mix, the level of start-up costs and efficiencies
of new programs, product life cycles, sales volumes, price erosion within the
electronics industry, capacity utilization of surface mount and other equipment,
labor costs and efficiencies, the management of inventories, component pricing
and shortages, average sales prices, the mix of turnkey and consignment
business, fluctuations and timing of customer orders, changing demand for
customers' products and competition within the electronics industry. Overall
gross margins continue to be affected by a slowdown in end-market demand,
particularly in the networking/datacommunications industry and its impact on our
capacity utilization.

In addition, gross margins continue to be affected by acquisitions. In
particular, gross margins resulting from the Mexico turnkey operations, Keltek
and Qtron are below our historical gross margins as we work to integrate these
acquisitions into our product realization model and increase their capacity
utilization. These and other factors can cause variations in our operating
results. Although our focus is on maintaining and expanding




12
gross margins, there can be no assurance that gross margins will not decrease in
future periods. Gross margins have decreased from fiscal 2000 results due to the
impact of the Company's recent acquisitions and its reduced manufacturing
capacity utilization.

Gross profit for the year ended September 30, 2000, increased 61
percent to $107.2 million from $66.4 million for the year ended September 30,
1999. The gross margin for the year ended September 30, 2000, was 14.3 percent,
compared to 13.5 percent for the year ended September 30, 1999. The improvement
in gross margin in fiscal 2000 compared to fiscal 1999 reflected the Company's
focus on business mix, leading-technology products and markets, continued
operating efficiencies and the one-time fiscal 1999 SeaMED merger-related
charges, which were partially offset by increased costs for expansion of
engineering and technical manufacturing capabilities to meet customer demands.

Most of the research and development we conduct is paid for by our
customers and is, therefore, included in the cost of sales. We conduct other
research and development, but that research and development is not specifically
identified and we believe such expenses are less than one percent of our net
sales.

Operating expenses. Selling and administrative (S&A) expenses for the
year ended September 30, 2001, increased to $55.8 million from $35.0 million and
$26.3 million for the years ended September 30, 2000 and 1999, respectively. As
a percentage of net sales, S&A expenses were 5.3 percent for the year ended
September 30, 2001, compared to 4.7 percent and 5.3 percent for the years ended
September 30, 2000 and 1999, respectively. The increase in dollar terms and
percentage of net sales was due primarily to increases in our sales and
marketing efforts and information systems support. In addition, the Company's
decision to increase reserves for bad debts due to increased credit risk
resulting from the overall weakness in the economy also impacted these expenses.
We anticipate that future S&A expenses will increase in absolute dollars, but
should remain at approximately five percent of net sales, as we continue to
expand these support areas.

Amortization of goodwill increased to $4.0 million for the year ended
September 30, 2001 from $1.1 million and $0.1 million for the years ended
September 30, 2000 and 1999, respectively. This was a result of the acquisitions
of the Mexico turnkey operations, Keltek and Qtron over the last 18 months which
resulted in additional goodwill.

Merger and acquisition costs of approximately $1.6 million for the year
ended September 30, 2001, were related to the Qtron and e2E acquisitions. In
fiscal 2000 and 1999, we also had one-time merger and acquisition costs of $1.1
million and $4.6 million, respectively.

In response to the reduction in our sales levels and reduced capacity
utilization, the Company reduced its cost structure through the reduction of its
work force and writing off certain under-utilized assets. The Company recorded a
pre-tax charge during fiscal 2001 of $1.9 million associated with this
restructuring. For the three months ended December 31, 2001, the Company has
incurred additional planned capacity reductions at certain sites which it
expects will result in one-time restructuring charges of approximately $2
million. In addition, the Company will incur one-time transaction charges
associated with the MCMS asset purchase.

In connection with the SeaMED merger in fiscal 1999, the Company
recorded a pre-tax charge of $1.0 million related to plant closing, relocations
and severance costs.

Income taxes. Income taxes decreased to $26.2 million for the year
ended September 30, 2001, from $28.4 million and increased from $15.8 million
for the years ended September 30, 2000 and 1999, respectively. Our effective
income tax rate has remained at approximately 40 percent excluding
non-tax-deductible merger expenses. This rate approximates the blended federal
and state statutory rate. In fiscal 2002, we expect the annual effective tax
rate to decrease slightly as foreign operations increase as a percentage of the
Company's total operations.

LIQUIDITY AND CAPITAL RESOURCES

Cash flows provided by operating activities were $96.6 million for the year
ended September 30, 2001, compared to cash flows (used in)/provided by operating
activities of ($51.4) million and $19.7 million for the years ended September
30, 2000 and 1999, respectively. During fiscal 2001, cash provided by operating
activities was primarily





13
related to net income, decreases in accounts receivable and inventories, and was
offset by decreases in accounts payable and accrued liabilities. The decrease in
our inventory levels resulted in the Company increasing inventory turns to 5.3
turns for the year ended September 30, 2001 from 4.4 turns for the year ended
September 30, 2000. This increase in inventory turns was primarily the result an
improved marketplace for components and improved inventory management.

Cash flows used in investing activities totaled $107.9 million for the
year ended September 30, 2001. The primary uses were payments for the
acquisition of Qtron, payments for property, plant and equipment, and net
payments for short-term investments.

We utilize available cash, debt and leases to fund our operating
requirements. We utilize operating leases primarily in situations where
technical obsolescence concerns are determined to outweigh the benefits of
financing the equipment purchase. We currently estimate capital expenditures for
fiscal 2002 will be approximately $40 million to $50 million. This estimate does
not include MCMS or any other acquisitions which the Company may undertake.
Management expects to fund the MCMS acquisition from Plexus' existing capital
resources and borrowing facilities.

Cash flows provided by financing activities totaled $90.6 million for
the year ended September 30, 2001 primarily represent proceeds from issuances of
common stock and proceeds from the exercise of stock options offset by net
payments on our credit facilities. The ratio of total debt to equity was 0.4 to
1 and 1.5 to 1 as of September 30, 2001 and 2000, respectively.

On October 25, 2000, the Company entered into a new unsecured revolving
credit facility (the "Credit Facility") with a group of banks. The Credit
Facility allows us to borrow up to $250 million. Borrowing capacity utilized
under the Credit Facility will be either through revolving or other loans or
through guarantees of commercial paper. Interest on borrowings is computed at
the applicable eurocurrency rate on the agreed currency, plus any commitment
fees. The Credit Facility matures on October 25, 2003, and requires among other
things maintenance of minimum interest expense coverage and maximum leverage
ratios.

Pursuant to a public offering of shares of common stock in the first
quarter of fiscal 2001, the Company issued 3.45 million shares of common stock
for $50 per share, with an underwriters discount of $2.375 per share. The
Company received net proceeds of approximately $164.3 million, after discounts
and commissions to the underwriters of approximately $8.2 million. Additional
expenses were approximately $0.6 million. The net proceeds from the offering
were utilized to refinance, in part, existing debt and finance capital
expenditures, and capacity expansion and the Qtron acquisition. The remaining
net proceeds were used for general corporate purposes and working capital.

In fiscal 2001, the Company entered into an agreement to sell up to $50
million of trade accounts receivable without recourse to Plexus ABS Inc.
("ABS"), a wholly owned, limited purpose subsidiary of the Company. ABS is a
separate corporate entity that sells participating interests in a pool of the
Company's accounts receivable to financial institutions. The financial
institutions then receive an ownership and security interest in the pool of
receivables.

Our credit facilities, leasing capabilities, the proceeds of our fiscal
2001 common stock offering, cash and short-term investments and projected cash
from operations should be sufficient to meet our working capital and capital
requirements through fiscal 2002 and the foreseeable future. We have not paid
cash dividends in the past, and do not anticipate paying them in the foreseeable
future. We anticipate using earnings to support our business.

NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities" was issued and requires the Company to recognize all
derivatives as either assets or liabilities and measure those instruments at
fair value. The Company adopted SFAS No. 133, as amended by SFAS No. 137 and
SFAS No. 138, on October 1, 2000. Given the Company's derivative and hedging
activities, the SFAS No. 133 did not have a significant material effect on its
financial position or results of operations upon adoption. The Company
periodically enters into derivative contracts, primarily foreign currency
forward, call and put contracts which are designated as cash-flow





14
hedges. The changes in fair value of these contracts, to the extent the hedges
are effective, are recognized in other comprehensive income until the hedged
item is recognized in earnings.

In fiscal 2001, the Company adopted SFAS No. 140, "Accounting for
Transfers and Servicing of Financial Assets and Extinguishments of Liabilities,
a replacement of SFAS No. 125." The statement revises the standards for
accounting for securitizations and other transfers of financial assets and
collateral, and requires certain disclosures and it continues most of SFAS No.
125's provisions without reconsideration. The statement is effective for
transfers and servicing of financial assets and extinguishments of liabilities
occurring after March 31, 2001, and did not have a material effect on the
Company's financial statements.

In fiscal 2001, the Company adopted the Securities and Exchange
Commission's Staff Accounting Bulletin ("SAB") No. 101, "Revenue Recognition in
Financial Statements." This bulletin summarizes certain views of the SEC staff
for applying generally accepted accounting principles to revenue recognition in
financial statements. SAB No. 101 was effective for the Company's fourth quarter
of fiscal 2001 and did not have a material effect on the Company's financial
statements.

In July 2001, SFAS No. 141, "Business Combinations" and No. 142,
"Goodwill and Other Intangible Assets" were issued. The statements eliminate the
pooling-of-interests method of accounting for business combinations and require
that goodwill and certain intangible assets not be amortized. Instead, these
assets will be reviewed for impairment annually with any related losses
recognized in earnings when incurred. SFAS No. 141 was effective for the Company
for business combinations completed subsequent to June 30, 2001. SFAS No. 142
will be effective for the Company's first quarter of fiscal 2003 for existing
goodwill and intangible assets. The Company is permitted to adopt the provisions
of SFAS No. 142 as of October 1, 2001. The Company is currently evaluating the
impact of SFAS No. 142 and whether to adopt its provisions early.

In August 2001, SFAS No. 143, "Accounting for Asset Retirement
Obligations" was issued. SFAS No. 143 sets forth the financial accounting and
reporting to be followed for obligations associated with the retirement of
tangible long-lived assets and the associated asset retirement costs. SFAS No.
143 requires entities to record the fair value of a liability for an asset
retirement obligation in the period in which it is incurred if a reasonable
estimate of fair value can be made. The associated asset retirement costs are to
be capitalized as part of the carrying amount of the long-lived asset.
Subsequently, the recorded liability will be accreted to its present value and
the capitalized costs will be depreciated. SFAS No. 143 will be effective for
the Company's first quarter of fiscal 2003 and is not expected to have a
material effect on its financial position or results of operations.

In October 2001, SFAS No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets" was issued. SFAS No. 144 modifies and expands the
financial accounting and reporting for the impairment or disposal of long-lived
assets other than goodwill, which is specifically addressed by SFAS No. 142.
SFAS No. 144 maintains the requirement that an impairment loss be recognized for
a long-lived asset to be held and used if its carrying value is not recoverable
from its undiscounted cash flows, with the recognized impairment being the
difference between the carrying amount and fair value of the asset. With respect
to long-lived assets to be disposed of other than by sale, SFAS No. 144 requires
that the asset be considered held and used until it is actually disposed of, but
requires that its depreciable life be revised in accordance with APB Opinion No.
20, "Accounting Changes." SFAS No. 144 also requires that an impairment loss be
recognized at the date a long-lived asset is exchanged for a similar productive
asset. SFAS No. 144 will be effective for the Company's first quarter of fiscal
2003. The Company is currently evaluating the impact of SFAS No. 144.

RISK FACTORS

OUR CUSTOMER REQUIREMENTS AND OPERATING RESULTS VARY SIGNIFICANTLY FROM QUARTER
TO QUARTER, WHICH COULD NEGATIVELY IMPACT THE PRICE OF OUR COMMON STOCK.

Our quarterly and annual results may vary significantly depending on
various factors, many of which are beyond our control. These factors include:

- the volume of customer orders relative to our capacity





15
-    the timing of customer orders, particularly in light of the fact
that some of our customers release a significant percentage of
their orders during the last few weeks of a quarter - the typical
short life cycle of our customers' products
- market acceptance of and demand for our customers' products
- changes in our sales mix to our customers
- the timing of our expenditures in anticipation of future orders
- our effectiveness in managing manufacturing processes
- changes in cost and availability of labor and components
- changes in economic conditions
- local events that may affect our production volume, such as local
holidays.

The EMS industry is impacted by the state of the U.S. and global
economies and world events (such as the September 11, 2001 attacks). Any
slowdown in the U.S. or global economies, or in particular in the industries
served by us, may result in our customers reducing their forecasts. The
Company's sales growth has been, and is expected to continue to be, impacted by
the slowdown in the networking/datacommunications and computer markets, as well
as the economy in general. As a result, the demand for our services could
decrease, which in turn would impact our sales and our capacity utilization.

Due to the nature of turnkey manufacturing services, our quarterly and
annual results are affected by the level and timing of customer orders,
fluctuations in material costs and availability, and the degree of capacity
utilization in the manufacturing process.

OUR CUSTOMERS MAY CANCEL THEIR ORDERS, CHANGE PRODUCTION QUANTITIES OR DELAY
PRODUCTION.

Electronics manufacturing service providers must provide increasingly
rapid product turnaround for their customers. We generally do not obtain firm,
long-term purchase commitments from our customers and we continue to experience
reduced lead-times in customer orders. Customers may cancel their orders, change
production quantities or delay production for a number of reasons. The success
of our customers' products in the market affects our business. Cancellations,
reductions or delays by a significant customer or by a group of customers could
seriously harm our operating results. Such cancellations, reductions or delays
have occurred and may continue to occur in response to the slowdown in the
networking/datacommunications market and other sectors of the economy.

In addition, we make significant decisions, including determining the
levels of business that we will seek and accept, production schedules, component
procurement commitments, personnel needs and other resource requirements, based
on our estimates of customer requirements. The short-term nature of our
customers' commitments and the possibility of rapid changes in demand for their
products reduces our ability to estimate accurately the future requirements of
those customers.

On occasion, customers may require rapid increases in production, which
can stress our resources and reduce operating margins. Although we have
increased our manufacturing capacity and plan further increases, we may not have
sufficient capacity at any given time to meet all of our customers' demands. In
addition, because many of our costs and operating expenses are relatively fixed,
a reduction in customer demand can harm our gross margins and operating results.

WE MAY NOT BE ABLE TO OBTAIN RAW MATERIALS OR COMPONENTS FOR OUR ASSEMBLIES ON A
TIMELY BASIS OR AT ALL.

We rely on a limited number of suppliers for many components used in
the assembly process. We do not have any long-term supply agreements. At various
times, there have been shortages of some of the electronic components that we
use, and suppliers of some components have lacked sufficient capacity to meet
the demand for these components. During the majority of fiscal 2000 and early
fiscal 2001, component shortages were prevalent in our industry, and in certain
areas have continued to occur. In some cases, supply shortages and delays in
deliveries of particular components have resulted in curtailed production, or
delays in production, of assemblies using that component, which contributed to
an increase in our inventory levels. We expect that shortages and delays in
deliveries of some components will continue. If we are unable to obtain
sufficient components on a timely basis, we





16
may experience manufacturing and shipping delays, which could harm our
relationships with customers and reduce our sales.

A significant portion of our sales is derived from turnkey
manufacturing in which we provide materials procurement. While most of our
customer contracts permit quarterly or other periodic adjustments to pricing
based on decreases and increases in component prices and other factors, we
typically bear the risk of component price increases that occur between any such
repricings or, if such repricing is not permitted, during the balance of the
term of the particular customer contract. Accordingly, component price increases
could adversely affect our operating results.

THE MAJORITY OF OUR SALES COMES FROM A SMALL NUMBER OF CUSTOMERS AND IF WE LOSE
ANY OF THESE CUSTOMERS, OUR SALES AND OPERATING RESULTS COULD DECLINE
SIGNIFICANTLY.

Sales to our ten largest customers have represented a majority of our
sales in recent periods. Our ten largest customers accounted for approximately
51 percent, 63 percent and 61 percent of our net sales for the years ended
September 30, 2001, 2000 and 1999, respectively. The identities of our principal
customers have varied from year to year, and our principal customers may not
continue to purchase services from us at current levels, if at all. Significant
reductions in sales to any of these customers, or the loss of major customers,
could seriously harm our business. If we are not able to timely replace expired,
canceled or reduced contracts with new business, our sales will decrease.

WE MAY HAVE INCREASING NEW CUSTOMER RELATIONSHIPS WITH EMERGING COMPANIES, WHICH
MAY PRESENT MORE RISKS THAN WITH ESTABLISHED COMPANIES.

We currently anticipate that an increasing percentage of our sales will
be to emerging companies, including start-ups, particularly in the
networking/datacommunications market. However, similar to our other customer
relationships, there are no volume purchase commitments under these new
programs, and the revenues we actually achieve may not meet our expectations. In
anticipation of future activities under these programs, we incur substantial
expenses as we add personnel and manufacturing capacity and procure materials.
Because emerging companies do not have a history of operations, it will be
harder for us to anticipate needs and requirements than with established
customers. Our operating results will be harmed if sales do not develop to the
extent and within the time frame we anticipate.

Customer relationships with emerging companies also present special
risks. For example, because they do not have an extensive product history, there
is less demonstration of market acceptance of their products. Also, due to the
current economic environment, additional funding for such companies may be more
difficult to obtain. This tightening of financing for start-up customers,
together with many start-up customers' lack of prior earnings and unproven
product markets could potentially increase the Company's credit risk, especially
in accounts receivable and inventories. Although the Company adjusts its
reserves for accounts receivable and inventories for all customers, including
start-up customers, based on the information available, these reserves may not
be adequate.

WE MAY FAIL TO COMPLETE SUCCESSFULLY FUTURE ACQUISITIONS AND MAY NOT INTEGRATE
SUCCESSFULLY ACQUIRED BUSINESSES, WHICH COULD ADVERSELY AFFECT OUR OPERATING
RESULTS.

We have pursued a strategy that has included growth through
acquisitions, and have pending the acquisition of certain assets of MCMS. We
cannot assure you that we will be able to complete successfully future
acquisitions, due primarily to increased competition for the acquisition of
electronics manufacturing service operations. If we are unable to acquire
additional businesses, our growth could be inhibited. Similarly, we cannot
assure you that we will be able to integrate successfully the operations and
management of our recent acquisitions, MCMS or future acquisitions. Acquisitions
involve significant risks that could have a material adverse effect on us. These
risks include:

OPERATING RISKS, SUCH AS THE:

- inability to integrate successfully our acquired operations'
businesses and personnel
- inability to realize anticipated synergies, economies of scale or
other value




17
-  difficulties in scaling up production and coordinating management of
operations at new sites
- strain placed on our personnel, systems and resources
- possible modification or termination of an acquired business
customer program, including cancellation of current or anticipated
programs
- loss of key employees of acquired businesses.

FINANCIAL RISKS, SUCH AS THE:

- dilutive effect of the issuance of additional equity securities
- incurrence of additional debt and related interest costs
- inability to achieve expected operating margins to offset the
increased fixed costs associated with acquisitions, and/or inability
to increase margins at acquired entities to Plexus' historical
levels
- incurrence of large write-offs or write-downs
- amortization and/or impairment of goodwill or other intangible
assets
- unforeseen liabilities of the acquired businesses.

EXPANSION OF OUR BUSINESS AND OPERATIONS MAY NEGATIVELY IMPACT OUR BUSINESS.

We may expand our operations by establishing or acquiring new
facilities or by expanding capacity in our current facilities. We may expand
both in geographical areas in which we currently operate and in new geographical
areas within the United States and internationally. We may not be able to find
suitable facilities on a timely basis or on terms satisfactory to us. Expansion
of our business and operations involves numerous business risks, including the:

- inability to integrate successfully additional facilities or capacity
and to realize anticipated synergies, economies of scale or other value
- additional fixed costs which may not be fully absorbed by the new
business
- difficulties in the timing of expansions, including delays in the
implementation of construction and manufacturing plans
- diversion of management's attention from other business areas during
the planning and implementation of expansions
- strain placed on our operational, financial, management, technical and
information systems and resources
- disruption in manufacturing operations
- incurrence of significant costs and expenses
- inability to locate enough customers or employees to support the
expansion.

OPERATING IN FOREIGN COUNTRIES EXPOSES US TO INCREASED RISKS.

We have acquired operations in Mexico and the United Kingdom. In
addition, as part of the MCMS acquisition, we expect to acquire in early
January, subject to closing conditions, operations located in China and
Malaysia. We may in the future expand into other international regions. We have
limited experience in managing geographically dispersed operations and in
operating in Mexico and the United Kingdom, and no prior experience in China and
Malaysia. We also purchase a significant number of components manufactured in
foreign countries. Because of these international aspects of our operations, we
are subject to the following risks that could materially impact our operating
results:

- economic or political instability
- transportation delays or interruptions and other effects of less
developed infrastructure in many countries
- foreign exchange rate fluctuations
- utilization of different systems and equipment
- difficulties in staffing and managing foreign personnel and diverse
cultures
- the effects of international political developments.




18
In addition, changes in policies by the U.S. or foreign governments
could negatively affect our operating results due to changes in duties, tariffs,
taxes or limitations on currency or fund transfers. Also, our Mexico based
operation utilizes the Maquiladora program, which provides reduced tariffs and
eases import regulations, and we could be adversely affected by changes in that
program.

WE MAY NOT BE ABLE TO MAINTAIN OUR ENGINEERING, TECHNOLOGICAL AND MANUFACTURING
PROCESS EXPERTISE.

The markets for our manufacturing and engineering services are
characterized by rapidly changing technology and evolving process development.
The continued success of our business will depend upon our ability to:

- hire, retain and expand our qualified engineering and technical
personnel
- maintain and enhance our technological capabilities
- develop and market manufacturing services which meet changing customer
needs
- successfully anticipate or respond to technological changes in
manufacturing processes on a cost-effective and timely basis.

Although we believe that our operations utilize the assembly and
testing technologies, equipment and processes that are currently required by our
customers, we cannot be certain that we will develop the capabilities required
by our customers in the future. The emergence of new technology industry
standards or customer requirements may render our equipment, inventory or
processes obsolete or noncompetitive. In addition, we may have to acquire new
assembly and testing technologies and equipment to remain competitive. The
acquisition and implementation of new technologies and equipment may require
significant expense or capital investment which could reduce our operating
margins and our operating results. Our failure to anticipate and adapt to our
customers' changing technological needs and requirements could have an adverse
effect on our business.

FAILURE TO MANAGE OUR GROWTH MAY SERIOUSLY HARM OUR BUSINESS.

We have experienced rapid growth, both internally and through
acquisitions. This growth has placed, and will continue to place, significant
strain on our operations. To manage our growth effectively, we must continue to
improve and expand our financial, operational and management information
systems; continue to develop the management skills of our managers and
supervisors; and continue to train, manage and motivate our employees. If we are
unable to manage our growth effectively, our operating results could be harmed.

Plexus has entered into a licensing arrangement for new ERP software
and related information systems. Conversions to new software and systems are
complicated processes, and can cause management and operational disruptions
which may affect Plexus. Information flow and production could also be affected
if the new software and systems do not perform as Plexus expects.

OUR TURNKEY MANUFACTURING SERVICES INVOLVE INVENTORY RISK.

Most of our contract manufacturing services are provided on a turnkey
basis, where we purchase some or all of the materials required for designing,
product assembling and manufacturing. These services involve greater resource
investment and inventory risk management than consignment services, where the
customer provides these materials. Accordingly, various component price
increases and inventory obsolescence could adversely affect our selling price,
gross margins and operating results.

START-UP COSTS AND INEFFICIENCIES RELATED TO NEW PROGRAMS CAN ADVERSELY AFFECT
OUR OPERATING RESULTS.

Start-up costs, the management of labor and equipment resources in
connection with the establishment of new programs and new customer
relationships, and the need to estimate required resources in advance can
adversely affect our gross margins and operating results. These factors are
particularly evident in the early stages of the life cycle of new products and
new programs. These factors also affect our ability to efficiently use labor and
equipment. In addition, if any of these new programs or new customer
relationships were terminated, our operating results could be harmed,
particularly in the short term.



19
WE ARE SUBJECT TO EXTENSIVE GOVERNMENT REGULATIONS.

We are also subject to environmental regulations relating to the use,
storage, discharge, recycling and disposal of hazardous chemicals used in our
manufacturing process. If we fail to comply with present and future regulations,
we could be subject to future liabilities or the suspension of business. These
regulations could restrict our ability to expand our facilities or require us to
acquire costly equipment or incur significant expense. While we are not
currently aware of any material violations, we may have to spend funds to comply
with present and future regulations or be required to perform site remediation.

In addition, our medical device business, which represented
approximately 22% of our fiscal year 2001 sales, is subject to substantial
government regulation, primarily from the FDA and similar regulatory bodies in
other countries. We must comply with statutes and regulations covering the
design, development, testing, manufacturing and labeling of medical devices and
the reporting of certain information regarding their safety. Noncompliance with
these rules can result in, among other things, us and our customers being
subject to fines, injunctions, civil penalties, criminal prosecution, recall or
seizure of devices, total or partial suspension of production, failure of the
government to grant pre-market clearance or record approvals for projections or
the withdrawal of marketing approvals. The FDA also has the authority to require
repair or replacement of equipment, or refund of the cost of a device
manufactured or distributed by our customers. In addition, the failure or
noncompliance could have an adverse effect on our reputation.

OUR PRODUCTS ARE FOR THE ELECTRONICS INDUSTRY, WHICH PRODUCES TECHNOLOGICALLY
ADVANCED PRODUCTS WITH SHORT LIFE CYCLES.

Factors affecting the electronics industry, in particular the short
life cycle of products, could seriously harm our customers and, as a result, us.
These factors include:

- the inability of our customers to adapt to rapidly changing technology
and evolving industry standards, which result in short product life
cycles
- the inability of our customers to develop and market their products,
some of which are new and untested
- the potential that our customers' products may become obsolete or the
failure of our customers' products to gain widespread commercial
acceptance.

INCREASED COMPETITION MAY RESULT IN DECREASED DEMAND OR PRICES FOR OUR SERVICES.

The electronics manufacturing services industry is highly competitive.
We compete against numerous U.S. and foreign electronics manufacturing services
providers with global operations, as well as those who operate on a local or
regional basis. In addition, current and prospective customers continually
evaluate the merits of manufacturing products internally. Consolidation in the
electronics manufacturing services industry results in a continually changing
competitive landscape. The consolidation trend in the industry also results in
larger and more geographically diverse competitors who have significant combined
resources with which to compete against us.

Some of our competitors have substantially greater managerial,
manufacturing, engineering, technical, financial, systems, sales and marketing
resources than we do. These competitors may:

- respond more quickly to new or emerging technologies
- have greater name recognition, critical mass and geographic and market
presence
- be better able to take advantage of acquisition opportunities
- adapt more quickly to changes in customer requirements
- devote greater resources to the development, promotion and sale of
their services
- be better positioned to compete on price for their services.

We may be operating at a cost disadvantage compared to manufacturers
who have greater direct buying power from component suppliers, distributors and
raw material suppliers or who have lower cost structures. As a result,
competitors may procure a competitive advantage and obtain business from our
customers. Our




20
manufacturing processes are generally not subject to significant proprietary
protection, and companies with greater resources or a greater market presence
may enter our market or increase their competition with us. Increased
competition could result in price reductions, reduced sales and margins or loss
of market share.

WE MAY FAIL TO SECURE NECESSARY ADDITIONAL FINANCING.

We have made and intend to continue to make substantial capital
expenditures to expand our operations, acquire businesses and remain competitive
in the rapidly changing electronics manufacturing services industry. Our future
success may depend on our ability to obtain additional financing and capital to
support our continued growth and operations, including our working capital
needs. We may seek to raise capital by:

- issuing additional common stock or other equity securities
- issuing debt securities
- increasing available borrowings under our existing credit facility or
obtaining new credit facilities
- obtaining off-balance-sheet financing.

We may not be able to obtain additional capital when we want or need
it, and capital may not be available on satisfactory terms. If we issue
additional equity securities or convertible debt to raise capital, it may be
dilutive to your ownership interest. Furthermore, any additional financing and
capital may have terms and conditions that adversely affect our business, such
as restrictive financial or operating covenants.

WE DEPEND ON CERTAIN KEY PERSONNEL, AND THE LOSS OF KEY PERSONNEL MAY HARM OUR
BUSINESS.

Our future success depends in large part on the continued service of
our key technical and management personnel, and on our ability to continue to
attract and retain qualified employees, particularly those highly skilled
design, process and test engineers involved in the development of new products
and processes and the manufacture of existing products. The competition for
these individuals is intense, and the loss of key employees, generally none of
whom is subject to an employment agreement for a specified term or a
post-employment non-competition agreement, could harm our business. We believe
that we have a relatively small management group whose resources could be
strained as a result of expansion of our business.

PRODUCTS WE MANUFACTURE MAY CONTAIN DESIGN OR MANUFACTURING DEFECTS WHICH COULD
RESULT IN REDUCED DEMAND FOR OUR SERVICES AND LIABILITY CLAIMS AGAINST US.

We manufacture products to our customers' specifications which are
highly complex and may at times contain design or manufacturing errors or
failures. Defects have been discovered in products we manufactured in the past
and, despite our quality control and quality assurance efforts, defects may
occur in the future. Defects in the products we manufacture, whether caused by a
design, manufacturing or component failure or error, may result in delayed
shipments to customers or reduced or cancelled customer orders. If these defects
occur in large quantities or too frequently, our business reputation may also be
impaired. In addition, these defects may result in liability claims against us.
The FDA investigates and checks, occasionally on a random basis, compliance with
statutory and regulatory requirements. Violations may lead to penalties or
shutdowns of a program or a facility.

THE PRICE OF OUR COMMON STOCK HAS BEEN AND MAY CONTINUE TO BE VOLATILE.

Our stock price has fluctuated significantly. The price of our common
stock may fluctuate significantly in response to a number of events and factors
relating to our company, our competitors and the market for our services, many
of which are beyond our control.

In addition, the stock market in general, and especially the NASDAQ
National Market along with market prices for technology companies, in
particular, have experienced extreme volatility that has often been unrelated to
the operating performance of these companies. These broad market and industry
fluctuations may adversely affect the market price of our common stock,
regardless of our operating results.




21
Among other things, volatility in Plexus' stock price could mean that
investors will not be able to sell their shares at or above the prices which
they pay. The volatility also could impair Plexus' ability in the future to
offer common stock as a source of additional capital and/or as consideration in
the acquisition of other businesses.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk from changes in foreign exchange and
interest rates. The pending MCMS asset acquisition will affect us in both of
these areas. To reduce such risks, we selectively use financial instruments. A
discussion of our accounting policy for derivative financial instruments is
incorporated by reference from our Consolidated Financial Statements and Notes
thereto, in this Form 10-K, within Note 1--"Description of Business and
Significant Accounting Policies."

FOREIGN CURRENCY RISK

We do not use derivative financial instruments for speculative
purposes. Our policy is to hedge our foreign currency denominated transactions
in a manner that substantially offsets the effects of changes in foreign
currency exchange rates. Presently, we use foreign currency forward contracts to
hedge only those currency exposures associated with certain assets and
liabilities denominated in non-functional currencies. We also use options to
hedge certain functional currency liabilities. Corresponding gains and losses on
the underlying transaction generally offset the gains and losses on these
foreign currency hedges. As of September 30, 2001, the foreign currency forward
and option contracts were scheduled to mature in less than three months and were
not material.

INTEREST RATE RISK

We have financial instruments, including cash equivalents, short-term
investments and long-term debt, which are sensitive to changes in interest
rates. We consider the use of interest-rate swaps based on existing market
conditions. We currently do not use any interest-rate swaps or other types of
derivative financial instruments to hedge interest rate risk.

The primary objective of our investment activities is to preserve
principal, while maximizing yields without significantly increasing market risk.
To achieve this, we maintain our portfolio of cash equivalents and short-term
investments in a variety of securities such as money market funds and
certificates of deposit and limit the amount of principal exposure to any one
issuer.

Our only material interest rate risk is associated with our credit
facilities and asset securitization facility. Interest on borrowings is computed
at the applicable Eurocurrency rate on the agreed currency. A 10 percent change
in our weighted average interest rate on average long-term borrowings would have
impacted net interest expense by approximately $0.6 million and $0.3 million for
fiscal 2001 and 2000, respectively. There were no material long-term borrowings
during fiscal 1999.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and
Board of Directors
Plexus Corp.:

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of shareholders' equity and of cash flows
present fairly, in all material respects, the financial position of Plexus Corp.
and its subsidiaries at September 30, 2001 and 2000, and the results of their
operations and their cash flows for each of the three years in the period ended
September 30, 2001 in conformity with accounting principles generally accepted
in the United States of America. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with auditing standards generally
accepted in the United States of America, which 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,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for our opinion.

PLEXUS CORP.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Description of Business: Plexus Corp. provides product
realization services to original equipment manufacturers (OEMs) in the
networking/datacommunications, medical, industrial, computer and
transportation industries. The Company offers a full range of services
including product development and design services, material procurement
and management, prototyping, manufacturing and assembly, functional and
in-circuit testing, final system box build, distribution and
after-market support.

The contract manufacturing services are provided on either a
turnkey basis, whereby the Company procures certain or all of the
materials required for product assembly, or on a consignment basis,
where the customer supplies materials necessary for product assembly.
Turnkey services include material procurement and warehousing, in
addition to manufacturing, and involve greater resource investment than
consignment services. Turnkey manufacturing currently represents almost
all of the Company's sales.

Consolidation Principles: The consolidated financial
statements include the accounts of Plexus Corp. and its subsidiaries
(together "the Company"). All significant intercompany transactions
have been eliminated.

On July 23, 1999, SeaMED Corporation ("SeaMED"), a public
company, was merged into Plexus. The consolidated financial statements
have been prepared following the pooling-of-interests method of
accounting for the merger and therefore reflect the combined financial
position, operating results and cash flows of the two companies for all
periods presented. SeaMED had a June 30 fiscal year end. For fiscal
1999, the combined financial statements reflect the October 1, 1998,
through September 30, 1999, period for both companies. SeaMED's results
of operations and cash flows from July 1, 1998, to September 30, 1998,
which have been excluded from the fiscal 1998 and 1999 consolidated
financial statements, are reflected as adjustments in the 1999
Consolidated Statements of Shareholders' Equity and Comprehensive
Income and Cash Flows.

Cash Equivalents and Short-Term Investments: Cash equivalents
are highly liquid investments purchased with an original maturity of
less than three months. Short-term investments include investment-grade
short-term debt instruments with original maturities greater than three
months. Short-term investments are generally comprised of securities
with contractual maturities greater than one year but with optional or
early redemption provisions within one year.

Investments in debt securities are classified as
"available-for-sale." Such investments are recorded at fair value as
determined from quoted market prices, and the cost of securities sold
is determined on the specific identification method. If material,
unrealized gains or losses are reported as a component of comprehensive
income or loss, net of the related income tax effect. At September 30,
2001, 2000 and 1999, such unrealized gains and losses were not
material. In addition, there were no realized gains or losses in fiscal
2001, 2000 and 1999.

Short-term investments as of September 30, 2001 consist
primarily of state and municipal securities. As of September 30, 2001
and 2000 cash and cash equivalents included the following securities:

Inventories: Inventories are valued primarily at the lower of
cost or market. Cost is determined by the first-in, first-out (FIFO)
method.

PLEXUS CORP.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED


Property, Plant and Equipment and Depreciation: These assets
are stated at cost. Depreciation, determined on the straight-line
method, is based on lives assigned to the major classes of depreciable
assets as follows:

Buildings and improvements 15-40 years
Machinery and equipment 3-10 years

Certain facilities and equipment held under capital leases are
classified as property, plant and equipment and amortized using the
straight-line method over the lease terms and the related obligations
are recorded as liabilities. Lease amortization is included in
depreciation expense.

Goodwill, net: Goodwill associated with acquisitions is
amortized using the straight-line method for periods of up to 15 years.
As of September 30, 2001 and 2000, goodwill is recorded net of
accumulated amortization of $5.6 million and $1.4 million,
respectively.

Impairment of Long-Lived Assets: The Company reviews property,
plant and equipment for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. Recoverability of property, plant and equipment is
measured by comparison of its carrying amount to future net cash flows
which the property, plant and equipment are expected to generate. If
such assets are considered to be impaired, the impairment to be
recognized is measured by the amount by which the carrying amount of
the property, plant and equipment, if any, exceeds its fair market
value. The Company assesses the recoverability of goodwill by
determining whether the unamortized goodwill balance can be recovered
through undiscounted future net cash flows of the acquired operation.
The amount of goodwill impairment, if any, is measured based on
projected discounted future net cash flows using a discount rate
reflecting the Company's average cost of funds. As of September 30,
2001, no adjustments to the carrying value of the Company's long-lived
assets were required. See also "New Accounting Pronouncements" below.

Revenue Recognition: Revenue is recognized primarily when
products are shipped. Revenue and profit relating to product design and
development contracts, which are short-term in duration, usually twelve
months or less, are recognized as costs are incurred utilizing the
percentage-of-completion method; any losses are recognized when
anticipated. Revenue from design and development contracts is less than
10% of total revenue in fiscal 2001, 2000 and 1999. Progress towards
completion of product design and development contracts is based on
units of work for labor content and costs incurred for component
content.

Restructuring Costs: In response to the reduction in our sales
levels and reduced capacity utilization during its third quarter of
fiscal 2001, the Company reduced its cost structure through the
reduction of its work force and the write-off of certain under-utilized
assets. The Company recorded a pre-tax charge during the quarter of
$1.9 million associated with this restructuring. As of September 30,
2001, there were no liabilities related to these restructuring
activities. In connection with the SeaMED merger in fiscal 1999, the
Company recorded a pre-tax charge of $1.0 million related to plant
closing, relocations and severance costs.

Income Taxes: Deferred income taxes are provided for
differences between the bases of assets and liabilities for financial
and income tax reporting purposes.

Foreign Currency: For foreign subsidiaries using the local
currency as their functional currency, assets and liabilities are
translated at exchange rates in effect at year-end, with revenues,
expenses and cash flows translated at the average of the monthly
exchange rates. Adjustments resulting from translation of the financial
statements are recorded as a component of accumulated other
comprehensive income. Exchange gains and losses arising from
transactions denominated in a currency other than the functional
currency of the entity involved and remeasurement adjustments for
foreign operation where the U.S. dollar is the functional currency are
included in the statement of operations. Exchange gains and losses on
foreign currency transactions were not significant for the years ended
September 30, 2001, 2000 and 1999, respectively.

PLEXUS CORP.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED

Derivatives: In June 1998, Statement of Financial Accounting
Standards ("SFAS") No. 133, "Accounting for Derivative Instruments and
Hedging Activities" was issued and requires the Company to recognize
all derivatives as either assets or liabilities and measure those
instruments at fair value. The Company adopted SFAS No. 133, as amended
by SFAS No. 137 and SFAS No. 138, on October 1, 2000. Given the
Company's derivative and hedging activities, SFAS No. 133 did not
have a material effect on its financial position or results of
operations upon adoption. The Company periodically enters into
derivative contracts, primarily foreign currency forward, call and put
contracts which are designated as cash-flow hedges. The changes in
fair-value of these contracts, to the extent the hedges are effective,
are recognized in other comprehensive income until the hedged item is
recognized in earnings.

Earnings Per Share: The computation of basic earnings per
common share is based upon the weighted average number of common shares
outstanding and net income. The computation of diluted earnings per
common share reflects additional dilution from stock options.

New Accounting Pronouncements: In fiscal 2001, the Company
adopted SFAS No. 140, "Accounting for Transfers and Servicing of
Financial Assets and Extinguishments of Liabilities, a replacement of
SFAS No. 125." The statement revises the standards for accounting for
securitizations and other transfers of financial assets and collateral,
and requires certain disclosures and it continues most of SFAS No.
125's provisions without reconsideration. The statement is effective
for transfers and servicing of financial assets and extinguishments of
liabilities occurring after March 31, 2001, and did not have a material
effect on the Company's financial statements.

In fiscal 2001, the Company adopted the Securities and
Exchange Commission's Staff Accounting Bulletin ("SAB") No. 101,
"Revenue Recognition in Financial Statements." This bulletin summarizes
certain views of the SEC staff for applying generally accepted
accounting principles to revenue recognition in financial statements.
SAB No. 101 was effective for the Company's fourth quarter of fiscal
2001 and did not have a material effect on the Company's financial
statements.

In July 2001, SFAS No. 141, "Business Combinations" and No.
142, "Goodwill and Other Intangible Assets" were issued. The statements
eliminate the pooling-of-interests method of accounting for business
combinations and require that goodwill and certain intangible assets
not be amortized. Instead, these assets will be reviewed for impairment
annually with any related losses recognized in earnings when incurred.
SFAS No. 141 was effective for business combinations completed
subsequent to June 30, 2001. SFAS No. 142 will be effective for the
Company's first quarter of fiscal 2003 for existing goodwill and
intangible assets. The Company is permitted to adopt the provisions of
SFAS No. 142 as of October 1, 2001. The Company is currently evaluating
the impact of SFAS No. 142 and whether to adopt its provisions early.

In August 2001, SFAS No. 143, "Accounting for Asset Retirement
Obligations" was issued. SFAS No. 143 sets forth the financial
accounting and reporting to be followed for obligations associated with
the retirement of tangible long-lived assets and the associated asset
retirement costs. SFAS No. 143 requires entities to record the fair
value of a liability for an asset retirement obligation in the period
in which it is incurred if a reasonable estimate of fair value can be
made. The associated asset retirement costs are to be capitalized as
part of the carrying amount of the long-lived asset. Subsequently, the
recorded liability will be accreted to its present value and the
capitalized costs will be depreciated. SFAS No. 143 will be effective
for the Company's first quarter of fiscal 2003 and is not expected to
have a material effect on its financial position or results of
operations.

In October 2001, SFAS No. 144, "Accounting for the Impairment
or Disposal of Long-Lived Assets" was issued. SFAS No. 144 modifies and
expands the financial accounting and reporting for the impairment or
disposal of long-lived assets other than goodwill, which is
specifically addressed by SFAS No. 142. SFAS No. 144 maintains the
requirement that an impairment loss be recognized for a long-lived
asset to be held and used if its carrying value is not recoverable from
its undiscounted cash flows, with the recognized impairment being the
difference between the carrying amount and fair value of the asset.
With respect to long-lived assets to be disposed of other than by sale,
SFAS No. 144 requires that the asset be considered held and used until
it is actually disposed of, but requires that its depreciable life be
revised in accordance with APB Opinion No. 20, "Accounting Changes."
SFAS No. 144 also requires that an impairment loss be recognized at the
date




32
a long-lived asset is exchanged for a similar productive asset. SFAS
No. 144 will be effective for the Company's first quarter of fiscal
2003. The Company is currently evaluating the impact of SFAS No. 144.

Use of Estimates: The preparation of financial statements in
conformity with accounting principles generally accepted in the United
States requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

Fair Value of Financial Instruments: Accounts receivable,
accounts payable and accrued liabilities are reflected in the
consolidated financial statements at cost because of the short-term
duration of these instruments. The fair value of long-term debt and
capital lease obligations closely approximates its carrying value. The
Company uses quoted market prices, when available or discounted cash
flows to calculate these fair values.

Business and Credit Concentrations: Financial instruments that
potentially subject the Company to concentrations of credit risk
consist of cash, cash equivalents, short-term investments and trade
accounts receivable. The Company's cash, cash equivalents and
short-term investments are managed by recognized financial institutions
which follow the Company's investment policy. Such investment policy
limits the amount of credit exposure in any one issue and the maturity
date of the investment securities that typically comprise investment
grade short-term debt instruments. Concentrations of credit risk in
accounts receivable resulting from sales to major customers are
discussed in Note 12. The Company, at times, requires advanced cash
deposits for services performed. The Company also closely monitors
extensions of credit.

Related Party Transactions: The Company has provided certain
engineering design and development services for MemoryLink Corp. which
develops electronic products. The Chairman of the Board of the Company
is a shareholder and director of MemoryLink. As of September 30, 2001
and 2000, the Company had $1.5 million and $0.7 million, respectively,
in accounts receivable due from MemoryLink. For the years ended
September 30, 2001, 2000 and 1999, the Company had $0.9 million, $2.9
million and $2.3 million, respectively, in sales to MemoryLink. The
Company has fully reserved the delinquent amounts due of $1.5 million
as of September 30, 2001, as the Company believes the amounts are
potentially uncollectible.

Reclassifications: Certain amounts in prior years'
consolidated financial statements have been reclassified to conform to
the 2001 presentation.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED

On October 25, 2000, the Company entered into a new unsecured
revolving credit facility (the "Credit Facility") with a group of
banks. The Credit Facility allows the Company to borrow up to $250
million. Borrowing capacity utilized under the Credit Facility will be
either through revolving or other loans or through guarantees of
commercial paper issued by the Company. Interest on borrowings is
computed at the applicable eurocurrency rate on the agreed currency,
plus any commitment fee. The Credit Facility matures on October 25,
2003 and requires among other things maintenance of minimum interest
expense coverage and maximum leverage ratios. The borrowings
outstanding as of September 30, 2001 of $44.6 million under the
Company's revolving credit agreement have been classified in the
Consolidated Balance Sheet as noncurrent based upon the terms of the
Credit Facility. As of September 30, 2001, the Company had total
borrowings available of $205 million under the Company's Credit
Facility.

On July 14, 2000, the Company acquired all the outstanding
capital stock of Keltek (Holdings) Limited ("Keltek"). In connection
with this acquisition, the Company issued a note payable on demand.
Interest is computed at 1% below the rate offered in the LIBOR rate for
three-month sterling borrowing.

The Company leases certain equipment and manufacturing
facilities, located in Europe and California, which have been recorded
as capital leases and expire on various dates through 2016 subject to
renewal options.

The aggregate scheduled maturities of the Company's debt and
its obligations under capital leases as of September 30, 2001, are as

In fiscal 2001, the Company entered into and amended an
agreement to sell up to $50 million of trade accounts receivable
without recourse to Plexus ABS Inc. ("ABS"), a wholly owned, limited
purpose subsidiary of the Company. ABS is a separate corporate entity
that sells participating interests in a pool of the Company's accounts
receivable to financial institutions. The financial institutions then
receive an ownership and security interest in the pool of receivables.
Accounts receivable sold to financial institutions, if any, are
reflected as a reduction to accounts receivable in the consolidated
balance sheets. The Company has no risk of credit loss on such
receivables as they are sold without recourse. The Company retains
collection and administrative responsibilities on the participation
interest sold as services for ABS and the financial institutions. The
agreement expires in October 2003. As of September 30, 2001, the
Company had utilized $22.9 million of the asset securitization
facility. The Company incurred interest expense of $1.9 million under
the asset securitization for the year ended September 30, 2001.

Cash paid for interest in fiscal 2001, 2000 and 1999 was $7.3
million, $1.1 million and $0.3 million, respectively.

The Company does not provide for taxes which would be payable
if undistributed earnings of foreign subsidiaries were remitted because
the Company either considers these earnings to be invested for an
indefinite period or anticipates that when such earnings are
distributed, the U.S. income taxes payable would be substantially
offset by foreign tax credits.

As of September 30, 2001, the Company has approximately $8.0
million of state net operating loss carryforwards, which are available
to reduce future state tax liabilities. The Company also has acquired
federal net operating losses of $17.0 million, which are available to
reduce federal taxable income. These loss carryforwards expire in

Cash paid for income taxes in fiscal 2001, 2000 and 1999 was
$23.4 million, $15.1 million and $16.3 million, respectively.

6. SHAREHOLDERS' EQUITY

In October 2001, pursuant to Board of Directors approval, the
Company announced a common stock buyback program which permits it to
acquire up to 1.0 million shares for an amount not to exceed $25.0
million.

During the first quarter of fiscal 2001, the Company issued
3.45 million shares of common stock at an offering price to the public
of $50 per share. The Company received net proceeds of approximately
$164.3 million after discounts and commissions to the underwriters of
approximately $8.2 million. Additional expenses were approximately $0.6
million.

On August 1, 2000, the Company declared a two-for-one stock
split payable in the form of a stock dividend of one share of common
stock for every share of common stock outstanding. The new common stock
was issued on August 31, 2000, to holders of record as of August 22,
2000. Share and per share amounts, where required, have been restated
to reflect this stock split.

On March 16, 1999, the Plexus Corp. Board of Directors
rescinded the Company's previous common stock buyback program in
contemplation of the merger with SeaMED.

The following is a reconciliation of the amounts utilized in
the computation of basic and diluted earnings per share (in thousands,
except per share amounts):

</TABLE>


For the year ended September 30, 2001, stock options to
purchase approximately 85,000 shares of common stock were outstanding,
but were not included in the computation of diluted earnings per share
because the exercise price of the stock options was greater than the
average market price of the common shares, and therefore their effect
would be antidilutive. There were no antidilutive stock options for the
years ended September 30, 2000 and 1999.

8. MERGERS AND ACQUISITIONS

Acquisitions: On May 23, 2001, the Company acquired Qtron,
Inc., ("Qtron") a privately held electronic manufacturing service
provider located in San Diego, California. The Company purchased all of
the outstanding shares of Qtron for approximately $29.0 million in
cash, paid outstanding Qtron notes payable of $3.6 million to Qtron
shareholders and assumed liabilities of $47.4 million, including
capital lease obligations of $18.8 million for a new manufacturing
facility. The excess of the cost over the fair value of the net assets
acquired of approximately $24 million has been recorded as goodwill and
is being amortized over 15 years. The purchase price is subject to
certain adjustments. The results of Qtron's operations have been
reflected in the Company's financial statements from the date of
acquisition.

Unaudited pro forma revenue, net income and earnings per share
as if the acquisition occurred as of the beginning of the period are as

The unaudited pro forma financial information is not
necessarily indicative of either the results of operations that would
have occurred had the acquisition been made during the periods
presented or the future results of the combined operations.

On July 14, 2000, the Company acquired all of the outstanding
capital stock of Keltek, headquartered in Kelso, Scotland, with an
additional facility in Maldon, England. The purchase price of $28.9
million consisted of a cash payment of $19.1 million, the assumption of
additional liabilities of $2.7 million and the issuance of a $7.1
million note payable. The Company accounted for the acquisition of
Keltek using the purchase method of accounting. The cost of the
acquisition has been allocated on the basis of the estimated fair
values of the assets acquired and the liabilities assumed. The excess
of the net assets acquired of $22.2 million was recorded as goodwill
and is being amortized over 15 years. The results of Keltek's
operations have been included in the Consolidated Statement of
Operations and of Cash Flows for the periods subsequent to July 14,
2000.

On May 23, 2000, the Company acquired the turnkey electronics
manufacturing services operations of Elamex, S.A. de C.V. ("the Mexican
turnkey operations"), located in Juarez, Mexico for approximately $54.3
million in cash subject to adjustment upon the final determination of
the purchase price. The Company accounted for the acquisition using
the purchase method of accounting. The cost of the acquisition has been
allocated on the basis of the estimated fair values of the assets
acquired and the liabilities assumed. The excess of the cost over fair
value of the net assets acquired has been recorded as goodwill and is
being amortized over 15 years. The results of the Mexican turnkey
operations have been included in the Consolidated Statement of
Operations and of Cash Flows for the periods subsequent to May 23,
2000.

Unaudited pro forma revenue, net income, earnings per
share-basic and earnings per share-diluted for fiscal 2000 as if Keltek
and the Mexican turnkey operations had been acquired at the beginning
of the period were $821.8 million, $38.5 million, $1.06 and $0.99,
respectively

On December 31, 1999, the Company acquired certain printed
circuit board assembly manufacturing assets in the Seattle, Washington,
area from an unrelated party. The total purchase price of the net
assets acquired was not material to the assets, shareholders' equity or
the operations of the Company. The acquisition was accounted for as a
purchase transaction and the results from operations of the acquired
assets are reflected only from the date of acquisition.

On September 1, 1999, the Company acquired certain printed
circuit board assembly manufacturing assets in Chicago, Illinois. The
total purchase price of the net assets acquired was not material to the
assets, shareholders' equity or the operations of the Company. The
acquisition was accounted for as a purchase transaction and the results
of operations of the acquired assets are reflected only from the date
of acquisition.

Mergers: On December 21, 2000, the Company merged with e2E
Corporation ("e2E"), a privately held printed circuit board design and
engineering service provider for electronic OEMs, through the issuance
of 462,625 shares of its common stock. The transaction was accounted
for as a pooling-of-interests. Costs associated with this merger in the
amount of $1.0 million ($1.0 million net of income taxes) have been
expensed as required. Prior results were not restated, as they would
not differ materially from reported results. The net assets of e2E as
of the acquisition date have been recorded in the Consolidated
Statement of Shareholders' Equity and Comprehensive Income in 2001.

On April 28, 2000, the Company merged with Agility,
Incorporated, located in Boston, Massachusetts, through the issuance of
374,997 (pre-split) shares of its common stock. The transaction is
being accounted for as a pooling-of-interests. Costs associated with
this merger in the amount of $0.7 million ($0.6 million net of income
tax benefit) have been expensed as required. Prior results are not
restated, as they would not differ materially from reported results.

In July 1999, Plexus merged with SeaMED. Plexus issued
approximately 2.27 million (pre-split) shares of its common stock in
exchange for all outstanding common stock of SeaMED. SeaMED stock
options outstanding, as of the merger date, were exchanged for options
to acquire approximately 171,764 (pre-split) shares of Plexus common
stock at the same time. All merger costs and other one-time expenses
related to the SeaMED merger were expensed as required under the
pooling-of-interests method of accounting. Certain merger-related costs
and charges related to obsolete inventories and a loss on an
engineering contract have been recorded in the Consolidated Statement
of Operations. Such costs and expenses amounted to $6.0 million after
income taxes in fiscal 1999 and are reflected in the consolidated
financial statements as follows (in thousands):

9. OPERATING LEASE COMMITMENTS

The Company has a number of operating lease agreements
primarily involving manufacturing facilities, manufacturing equipment
and computerized design equipment. These leases are non-cancelable and
expire on various dates through 2016. Rent expense under all operating
leases for fiscal 2001, 2000 and 1999 was approximately $10.9 million,
$12.1 million and $11.3 million, respectively. Renewal and purchase
options are available on certain of these leases. Rental income from
subleases amounted to $1.0 million, $0.9 million and $0 in fiscal 2001,
2000 and 1999, respectively.

10. BENEFIT PLANS

Employee Stock Purchase Plan: On March 1, 2000, the Company
established a qualified Employee Stock Purchase Plan, the terms of
which allow for qualified employees to participate in the purchase of
the Company's common stock at a price equal to the lower of 85% of the
average high and low stock price at the beginning or end of each
semi-annual stock purchase period. The Company may issue up to 2.0
million shares of its common stock under the plan. The Company issued
approximately 95,000 shares of common stock for $2.5 million under the
plan during fiscal 2001.

401(k) Savings Plans: The Company's 401(k) savings plans cover
all eligible employees. The Company matches employee contributions,
after one year of service, up to 2.5% of eligible earnings. The
Company's contributions for fiscal 2001, 2000 and 1999 totaled $2.1
million, $1.8 million and $1.6 million, respectively.

Stock Option Plans: The Company has reserved 12.0 million
shares of common stock for grant to officers and key employees under an
employee stock option plan, of which 9.9 million shares have been
granted. The exercise price of each option granted shall not be less
than the fair market value on the date of grant and options vest over a
three-year period from date of grant. The plan also authorizes the
Company to grant 600,000 stock appreciation rights, none of which have
been granted.

In connection with the SeaMED merger occurring in fiscal 1999,
all of the options outstanding under the former SeaMED stock option
plans were assumed by the Company and converted into options to
purchase shares of the Company's common stock on terms adjusted to
reflect the merger exchange ratio. Options to acquire a total of
429,410 SeaMED shares were converted into options to acquire a total of
171,764 (pre-split) Plexus shares. The SeaMED stock option plans are
similar to the Plexus plans above and options vest over a four-year
period from date of grant. These plans have been terminated; however,
the outstanding options, as so adjusted, retain all of the rights,
terms and conditions of the respective plans under which they were
originally granted until their expiration.

Under a separate stock option plan, each outside director of
the Company is granted 1,500 stock options each December 1, with the
option pricing similar to the employee plans. These options are fully
vested upon grant and can be exercised after a minimum six-month
holding period. The 400,000 shares of common stock authorized under
this plan may come from any combination of authorized but unissued
shares, treasury stock or the open market.

</TABLE>

The Company has elected to account for its stock option plans
under the guidelines of Accounting Principles Board Opinion No. 25.
Accordingly, no compensation cost related to the stock option plans has
been recognized in the Consolidated Statements of Operations. Had the
Company recognized compensation expense based on the fair value at the
grant date for awards under the plans, the Company's net income for
fiscal 2001, 2000 and 1999 would have been reduced by approximately
$6.7 million, $4.8 million and $2.8 million, respectively. Diluted
earnings per share would have been reduced by $0.15, $0.12 and $0.08 in
fiscal 2001, 2000 and 1999, respectively. These pro forma results will
not be representative of the impact in future years because only grants
made since October 1, 1995 were considered.

The weighted average fair value of options granted per share
during fiscal 2001, 2000 and 1999 is $16.00, $20.30 and $8.41,
respectively. The fair value of each option grant is estimated at the
date of grant

using the Black-Scholes prorated straight-line option-pricing method
with the following assumption ranges: 66% to 85% volatility, risk-free
interest rates ranging from 3.8% to 5.9%, expected option life of 4.3
to 6.2 years, and no expected dividends.

Deferred Compensation Plan: In September 1996, the Company
entered into agreements with certain of its officers under a
nonqualified deferred compensation plan. Under the plan, the Company
has agreed to pay certain amounts annually for the first 15 years
subsequent to retirement or to a designated beneficiary upon death. It
is management's intent that life insurance contracts owned by the
Company will fund this plan. Expense for this plan totaled
approximately $0.7 million, $0.5 million and $0.4 million in fiscal
2001, 2000, and 1999, respectively.

Other: The Company is not obligated to provide any
post-retirement medical or life insurance benefits to employees.

11. CONTINGENCY

The Company (along with many other companies) has been sued by
the Lemelson Medical, Education & Research Foundation Limited
Partnership ("Lemelson") related to alleged possible infringement of
certain Lemelson patents. The Company had requested a stay of action
pending developments in other related litigation, which has been
granted. The Company believes the vendors from whom the patent
equipment was purchased may contractually indemnify the Company. If a
judgment is rendered and/or a license fee required, it is the opinion
of management of the Company that such judgment would not be material
to the consolidated financial position of the Company or the results of
its operations.

12. BUSINESS SEGMENT, GEOGRAPHIC INFORMATION AND MAJOR CUSTOMERS

The Company operates in one business segment. The Company
provides product realization services to electronic OEMs. The Company
has two reportable geographic regions: North America and Europe. The
Company has 25 manufacturing and engineering facilities in North
America and Europe to serve these OEMs. The Company uses an internal
management reporting system, which provides important financial data,
to evaluate performance and allocate the Company's resources on a
geographic basis. Interregion transactions are generally recorded at
amounts that approximate arm's length transactions. Certain corporate
expenses are allocated to these regions and are included for
performance evaluation. The accounting policies for the regions are the
same as for the Company taken as a whole. Geographic net sales
information reflects the origin of the product shipped. Assets
information is based on the physical location of the asset.

On November 28, 2001, the Company signed an agreement to
acquire the majority of the assets of MCMS, Inc. ("MCMS"), an
electronics manufacturing services provider, for approximately $45
million, subject to certain adjustments. MCMS is currently in Chapter
11 bankruptcy proceedings. Assets to be purchased include certain
