PLEXUS CORP.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
FOR THE THREE MONTHS AND NINE MONTHS ENDED JULY 1, 2006
Unaudited
NOTE 1 — BASIS OF PRESENTATION
     The condensed consolidated financial statements included herein have been prepared by Plexus Corp. (“Plexus” or the “Company”) without audit and pursuant to the rules and regulations of the United States Securities and Exchange Commission. In the opinion of the Company, the financial statements reflect all adjustments, which include normal recurring adjustments necessary to present fairly the financial position of the Company as of July 1, 2006 and the results of operations for the three and nine months ended July 1, 2006 and July 2, 2005, and its cash flows for the same nine month periods.
     Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to the SEC rules and regulations dealing with interim financial statements. However, the Company believes that the disclosures made in the condensed consolidated financial statements included herein are adequate to make the information presented not misleading. It is suggested that these condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Company’s 2005 Annual Report on Form 10-K.
     The Company’s fiscal year ends on the Saturday closest to September 30 rather than on September 30, as was the case prior to fiscal 2005. The Company also has adopted a “4-4-5” weekly accounting system for the interim periods in each quarter. Each quarter therefore ends on a Saturday at the end of the 4-4-5 weekly period. The accounting periods for the third quarter of fiscal 2006 and 2005 each included 91 days. The accounting periods for the nine months ended July 1, 2006 and July 2, 2005, included 273 days and 275 days, respectively.
NOTE 2 — INVENTORIES
     The major classes of inventories are as follows (in thousands):
                 
    July 1,     October 1,  
    2006     2005  
Raw materials
  $ 167,144     $ 116,466  
Work-in-process
    34,726       30,282  
Finished goods
    30,954       33,350  
 
           
 
  $ 232,824     $ 180,098  
 
           
NOTE 3 — LONG-TERM DEBT AND CAPITAL LEASE OBLIGATIONS
     The Company is a party to a secured revolving credit facility (as amended, the “Secured Credit Facility”) with a group of banks that allows the Company to borrow up to $150 million and expires on October 31, 2007. Borrowings under the Secured Credit Facility may be either through revolving or swing loans or letter of credit obligations. As of July 1, 2006, the Company had no borrowings outstanding under the Secured Credit Facility. The Secured Credit Facility is secured by substantially all of the Company’s domestic working capital assets and a pledge of 65 percent of the stock of the Company’s foreign subsidiaries. The Secured Credit Facility contains certain financial covenants, which include certain minimum adjusted EBITDA amounts, maximum outstanding borrowings (not to exceed 2.5 times the adjusted EBITDA for the trailing four quarters) and a minimum tangible net worth, all as defined in the amended agreement. Interest on borrowings varies depending upon the Company’s then-current total leverage ratio and begins at the Prime rate, as defined, or LIBOR plus 1.5 percent. The Company is also required to pay an annual commitment fee of 0.5 percent of the unused credit commitment. Origination fees and expenses totaled approximately $1.4 million. The origination fees and expenses have been deferred and are being amortized to interest expense over the term of the Secured Credit Facility. Interest expense related to the commitment fee and amortization of deferred origination fees totaled approximately $0.3 million and $0.9 million for the three and nine

months ended July 1, 2006, respectively, and $0.3 million and $0.9 million for the three and nine months ended July 2, 2005, respectively.
NOTE 4 — EARNINGS PER SHARE
     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):
                                 
    Three Months Ended     Nine Months Ended  
    July 1,     July 2,     July 1,     July 2,  
    2006     2005     2006     2005  
Basic and Diluted Earnings Per Share:
                               
Net income (loss)
  $ 25,092     $ (21,498 )   $ 57,386     $ (22,934 )
 
                       
 
                               
Basic weighted average common shares outstanding
    45,848       43,369       44,793       43,291  
Dilutive effect of stock options
    1,426             1,598        
 
                       
Diluted weighted average shares outstanding
    47,274       43,369       46,391       43,291  
 
                       
 
                               
Earnings per share:
                               
Basic
  $ 0.55     $ (0.50 )   $ 1.28     $ (0.53 )
 
                       
Diluted
  $ 0.53     $ (0.50 )   $ 1.24     $ (0.53 )
 
                       
     For the three and nine months ended July 1, 2006, stock options to purchase approximately 0.4 million and 0.7 million shares of common stock, respectively, were outstanding but not included in the computation of diluted earnings per share because the options’ exercise prices were greater than the average market price of the common shares and therefore their effect would be anti-dilutive.
     For both the three and nine months ended July 2, 2005, stock options to purchase approximately 5.2 million shares of common stock were outstanding but not included in the computation of diluted earnings per share because there was a net loss in each period, and therefore their effect would be anti-dilutive.
NOTE 5 — STOCK-BASED COMPENSATION
     Effective October 2, 2005, the Company adopted Statement of Financial Accounting Standards No. 123 (R), “Share-Based Payment: An Amendment of Financial Accounting Standards Board Statements No. 123 and 95” (“SFAS No. 123(R)”), which revised SFAS No. 123, “Accounting for Stock-Based Compensation” and supersedes Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees.” SFAS No. 123(R) requires all share-based payments to employees, including grants of employee stock options, to be measured at fair value and expensed in the consolidated statement of operations over the service period (generally the vesting period) of the grant. Upon adoption, the Company transitioned to SFAS No. 123(R) using the modified prospective application, under which compensation expense is only recognized in the consolidated statements of operations beginning with the first period that SFAS No. 123(R) is effective and continuing to be expensed thereafter. Prior periods’ stock-based compensation expense is still presented on a pro-forma basis.
     Stock Option Plans: The Company’s shareholders have approved the 2005 Equity Incentive Plan (the “2005 Plan”). The 2005 Plan is a stock-based incentive plan for the Company and includes provisions by which the Company’s Compensation Committee of the Board of Directors may grant stock-based awards to directors, executive officers and other officers and key employees. The Compensation Committee of the Board of Directors may establish the terms and vesting periods of the stock options, as well as accelerate the vesting of stock options. Unless otherwise directed by the Compensation Committee, stock options vest over a three-year period from the date of grant and have a term of ten years.
     The maximum number of shares of Plexus common stock that may be issued pursuant to the 2005 Plan is 2.7 million shares. Under the 2005 Plan, the Company granted options to purchase 1.5 million shares of the Company’s common stock from the approval date of the 2005 Plan through July 1, 2006.

     As a result of the adoption of SFAS No. 123(R), the Company recognized $0.7 million and $1.7 million of compensation expense associated with stock options for the three and nine months ended July 1, 2006, respectively. The following presents pro-forma net income and per share data as if a fair-value-based method had been used to account for stock-based compensation for the three and nine months ended July 2, 2005 (in thousands, except per share amounts):

     The Company continues to use the Black-Scholes valuation model to value stock options. The Company used its historical stock prices as the basis for its volatility assumptions. The assumed risk-free rates were based on U.S. Treasury rates in effect at the time of grant and with a term consistent with the expected option lives. The expected option lives represent the period of time that the options granted are expected to be outstanding and were based on historical experience.
     The weighted average fair value per share of options granted for the three and nine months ended July 1, 2006 are $21.32 and $20.10, respectively. The weighted average fair value per share of options granted for the three and nine months ended July 2, 2005 are $5.43 and $5.68, respectively. The fair value of each option grant was estimated at the date of grant using the Black-Scholes option-pricing method based on the assumption ranges below:
                                 
    Three Months Ended   Nine Months Ended
    July 1,   July 2,   July 1,   July 2,
    2006   2005   2006   2005

     For the three and nine months ended July 1, 2006, the total intrinsic value of stock options exercised was $28.2 million and $50.5 million, respectively.
     As of July 1, 2006, there was $15.0 million of unrecognized compensation cost related to non-vested stock options that is expected to be recognized over a weighted average period of 2.8 years.

     Employee Stock Purchase Plans: The Company’s shareholders have also approved the 2005 Employee Stock Purchase Plan (the “2005 Purchase Plan”) under which the Company may issue up to 1.2 million shares of its common stock. The terms of the 2005 Purchase Plan allowed for qualified employees to participate in the purchase of the Company’s common stock at a price equal to the lower of 85 percent of the average high and low stock price at the beginning or end of each semi-annual stock purchase period. The 2005 Purchase Plan was effective on July 1, 2005 and terminates on June 30, 2010, unless all shares authorized under the 2005 Purchase Plan have been issued prior to that date.
     The Board of Directors of the Company amended the 2005 Purchase Plan to allow qualified employees to purchase the Company’s common stock at a price equal to 95 percent of the average high and low stock price at the end of each semi-annual purchase period. The effect of the amendment was to reduce the discount available to employees who purchase shares under the 2005 Purchase Plan. With the amendment, the Company does not expect to record any compensation expense related to the 2005 Purchase Plan under SFAS No. 123(R). The Company has issued 4,226 shares under the 2005 Purchase Plan during the three months and nine months ended July 1, 2006.
NOTE 6 — INCOME TAXES
     Income taxes for the three and nine months ended July 1, 2006 were $0.3 million and $0.6 million, respectively. The effective tax rates for the three and nine months ended July 1, 2006 were 1.3 percent and 1.0 percent, respectively. Income taxes for the three and nine months ended July 2, 2005 were $1.0 million and $0.9 million, respectively. The effective tax rate for the three and nine months ended July 2, 2005 was (5.0) percent and (4.0) percent, respectively. The reduction in our effective tax rate for the three and nine months ended July 1, 2006, compared to the three and nine months ended July 2, 2005, was due to increased profits in Asia, where we currently enjoy tax holidays, and in the United States where the carry-forward of net operating losses (“NOLs”), and the establishment in fiscal 2004 of a full-valuation allowance on deferred tax assets, result in no tax provision on U.S. income. As of July 1, 2006, the Company had a $44.3 million valuation allowance on U.S. deferred tax assets.
     U.S. GAAP requires us to periodically review our historical and projected levels of profitability in the United States, and we may be required to reduce the valuation allowance by crediting the tax provision for a portion of the remaining valuation allowance, which would have a beneficial impact on our effective tax rate. Once the U.S. valuation allowance is reversed, our effective tax rate is expected to increase.
NOTE 7 — GOODWILL AND OTHER INTANGIBLE ASSETS
     The Company adopted SFAS No. 142, “Goodwill and Other Intangible Assets” (“SFAS No. 142”) effective October 1, 2002. Under SFAS No. 142, the Company no longer amortizes goodwill and intangible assets with indefinite useful lives, but instead, the Company tests those assets for impairment at least annually, and recognizes any related losses when incurred. Recoverability of goodwill is measured at the reporting unit level. Upon the adoption of SFAS No. 142, the Company’s goodwill was originally assigned to three reporting units or operations: San Diego, California (“San Diego”), Juarez, Mexico (“Juarez”) and Kelso, Scotland and Maldon, England (“United Kingdom”). As of July 1, 2006, the Company had remaining goodwill of $7.3 million, all of which related to the operations in the United Kingdom.
     The Company is required to perform goodwill impairment tests at least on an annual basis, for which the Company selected the third quarter of each fiscal year, or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The Company’s fiscal 2006 annual impairment test did not result in any further impairment of the remaining goodwill in the United Kingdom. The fair value of the Company’s United Kingdom operations was primarily estimated using the present value of expected future cash flows. No assurances can be given that future impairment tests of the Company’s remaining goodwill will not result in additional impairment.
     In the third quarter of fiscal 2005, the Company recorded goodwill impairment of $26.9 million, of which $16.1 million represented a partial impairment of goodwill associated with the Company’s operations in the United Kingdom and $10.8 million represented a complete impairment of goodwill associated with the Company’s operations in Juarez.

Table of Contents

     In fiscal year 2005, the goodwill impairment of the Company’s United Kingdom operations arose primarily from a medical customer’s expressed intention to transfer future production from the Company’s United Kingdom operations to a lower-cost location by the end of fiscal 2006. The impairment also reflected lowered expectations for the United Kingdom’s electronics manufacturing services industry in general. Also in fiscal year 2005, the goodwill impairment associated with the Company’s Juarez operations reflected a lowered forecast of near-term profits and cash flows associated with recent operational issues and an anticipated transfer of a customer program to another Plexus manufacturing facility. The fair value of each of the Company’s United Kingdom and Juarez operations was primarily estimated using the present value of expected future cash flows, although market valuations were also utilized.
     The changes in the carrying amount of goodwill for the fiscal year ended October 1, 2005 and for the nine months ended July 1, 2006 for the various business segments are as follows (in thousands):

NOTE 8 — BUSINESS SEGMENT, GEOGRAPHIC AND MAJOR CUSTOMER INFORMATION
     Statement of Financial Accounting Standards No. 131, “Disclosures about Segments of an Enterprise and Related Information” (“SFAS No. 131”) establishes standards for reporting information about segments in financial statements. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or group, in assessing performance and allocating resources.
     The Company has aggregated its operating locations into four reportable geographical segments: United States, Asia, Mexico and Europe. As of July 1, 2006, the Company had 18 active manufacturing and/or engineering facilities in the United States, Asia, Mexico and Europe.
     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. Net sales for segments are attributed to the region in which the product is manufactured or service is performed. The services provided, manufacturing processes used, class of customers serviced and order fulfillment processes used are similar and generally interchangeable across the segments. A segment’s performance is evaluated based upon its operating income (loss). A segment’s operating income (loss) includes its net sales less cost of sales and selling and administrative expenses, but excludes corporate and other costs, interest expense, other income (loss), and income tax expense. Corporate and other costs primarily represent corporate selling and administrative expenses, and restructuring and impairment costs. These costs are not allocated to the segments, as management excludes such costs when assessing the performance of the segments. Inter-segment transactions are generally recorded at amounts that approximate arm’s length transactions. The accounting policies for the regions are the same as for the Company taken as a whole.

NOTE 9 — GUARANTEES
     The Company offers certain indemnifications under its customer manufacturing agreements. In the normal course of business, the Company may from time to time be obligated to indemnify its customers or its customers’

13


Table of Contents

customers against damages or liabilities arising out of the Company’s negligence, breach of contract, or infringement of third party intellectual property rights relating to its manufacturing processes. Certain of the manufacturing agreements have extended broader indemnification, and while most agreements have contractual limits, some do not. However, the Company generally does not provide for such indemnities, and seeks indemnification from its customers for damages or liabilities arising out of the Company’s adherence to customers’ specifications or designs or use of materials furnished, or directed to be used, by its customers. The Company does not believe its obligations under such indemnities are material.
     In the normal course of business, the Company also provides its customers a limited warranty covering workmanship, and in some cases materials, on products manufactured by the Company for them. Such warranty generally provides that products will be free from defects in the Company’s workmanship and meet mutually agreed-upon testing criteria for periods generally ranging from 12 months to 24 months. If a product fails to comply with the Company’s limited warranty, the Company’s obligation is generally limited to correcting, at its expense, any defect by repairing or replacing such defective product. The Company’s warranty generally excludes defects resulting from faulty components, design defects or damage caused by any party other than the Company.
     The Company provides for an estimate of costs that may be incurred under its limited warranty at the time product revenue is recognized and establishes reserves for specifically identified product issues. These costs primarily include labor and materials, as necessary, associated with repair or replacement. The primary factors that affect the Company’s warranty liability include the number of shipped units and historical and anticipated rates of warranty claims. As these factors are impacted by actual experience and future expectations, the Company assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary. During the nine months ended July 1, 2006, the Company incurred nominal warranty activity. As of July 1, 2006, the Company had a $1.0 million accrued warranty liability.
NOTE 10 — CONTINGENCIES
     The Company is party to certain lawsuits in the ordinary course of business. Management does not believe that these proceedings, individually or in the aggregate, will have a material adverse effect on the Company’s financial position, results of operations or cash flows.
NOTE 11 — RESTRUCTURING AND IMPAIRMENT COSTS
     Fiscal 2006 restructuring and asset impairment costs: For the three and nine months ended July 1, 2006, the Company recorded pre-tax restructuring and asset impairment costs of $0.6 million and $1.0 million, respectively, related to the decision to close its Maldon, England (“Maldon”) facility and to reduce the workforce in Juarez. For the three and nine months ended July 1, 2006, these restructuring costs were offset by reductions in lease obligations of $0.6 and $0.8 million, respectively, as a result of the Company entering into lease termination or sublease agreements for three of its previously closed facilities in the Bothell and Seattle, Washington area, as well as favorable adjustments of $0.2 million for the nine months ended July 1, 2006, related to other restructuring accruals. The details of these fiscal 2006 restructuring actions are listed below:
     Maldon Facility Closure: The Company announced its decision to close its Maldon facility. For the three months ended July 1, 2006, the Company recorded $0.5 million for severance and asset impairments related to the closure of the Maldon facility. This restructuring affected 77 employees. The Company expects to incur an additional $0.5 million for retention and other costs when the Maldon facility closes by the end of March 2007.
     Maldon Facility Conversion: In the third quarter of fiscal 2005, the Company announced a planned workforce reduction at the Maldon facility as the Company decided to convert this manufacturing facility to a fulfillment, service and repair facility. As a result of this planned conversion, the Company recorded expenses of $0.1 million and $0.2 million for retention bonuses for the three and nine months ended July 1, 2006 related to the workforce reduction as part of the Maldon facility conversion. This restructuring affected 43 employees.
     Other Restructuring Costs. For the nine months ended July 1, 2006, the Company recorded pre-tax restructuring costs of $0.3 million related to severance for its Juarez facility. The Juarez workforce reductions affected approximately 46 employees.

For the nine months ended July 2, 2005, these costs consisted of $6.2 million for the facility lease, $1.1 million for employee severance and retention bonuses and $0.2 million for other closure costs.
     Shop Floor Data-Collection System Impairment. For the nine months ended July 2, 2005, the Company recorded a $3.8 million impairment of the remaining elements of a shop floor data-collection system when it determined that the remaining value of the shop floor data-collection system was impaired because the anticipated business benefits could not be realized.
     Other Restructuring Costs. For the three and nine months ended July 2, 2005, the Company recorded $0.5 million and $1.0 million, respectively, of restructuring and asset impairment costs.
     For the three months ended July 2, 2005, the Company incurred other restructuring and asset impairment costs of $0.5 million, which consisted of the following:

    $0.2 million for the planned workforce reduction for the Maldon facility conversion noted above.
     For the nine months ended July 2, 2005, the Company incurred other restructuring and asset impairment costs of $1.0 million, which consisted of the following:
    $0.5 million which consisted of $0.4 million associated with a workforce reduction and $0.1 million in asset impairments in the Juarez facility. The Juarez workforce reduction affected approximately 50 employees.
 
    $0.3 million associated with the elimination of a corporate executive position.
 
    $0.2 million for the planned workforce reduction for the Maldon facility conversion noted above.

NOTE 12 — NEW ACCOUNTING PRONOUNCEMENTS
     In December 2004, the Financial Accounting Standards Board (“FASB”) issued Staff Position (“FSP”) FAS 109-2, “Accounting and Disclosure Guidance for the Foreign Earnings Repatriation Provision within the American Jobs Creation Act of 2004” (the “Act”). The Act became law in the U.S. in October 2004. This legislation provides for a number of changes in U.S. tax laws. FSP SFAS No. 109-2 requires recognition of a deferred tax liability for the tax effect of the excess of book over tax basis of an investment in a foreign corporate venture that is permanent in duration, unless a company firmly asserts that such amounts are indefinitely reinvested outside the company’s home jurisdiction. However, due to the lack of clarification of certain provisions within the Act, FSP SFAS No. 109-2 provides companies additional time beyond the financial reporting period of enactment to evaluate the effect of the Act on its plan for reinvestment or repatriation of foreign earnings for purposes of applying SFAS No. 109. We are presently reviewing this legislation, in conjunction with income tax legislation enacted in July 2005 in the United Kingdom, to determine the impacts on our consolidated results of operations and financial position.
     In March 2005, the FASB issued Interpretation No. 47, “Accounting for Conditional Asset Retirement Obligations” (“FIN 47”), which clarifies that an entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value can be reasonably estimated even though uncertainty exists about the timing and/or method of settlement. We will adopt FIN 47 in the fourth quarter of fiscal 2006. We estimate the impact of the adoption of FIN 47 to be approximately $0.9 million, or $0.02 per share, on our consolidated results of operations and financial position.
     In May 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections.” SFAS No. 154 replaces APB Opinion No. 20, “Accounting Changes,” and SFAS No. 3, “Reporting Accounting Changes in Interim Financial Statements,” and changes the requirements for the accounting for and reporting of a change in accounting principle. We are required to adopt SFAS No. 154 for accounting changes and error corrections in fiscal 2007. Our results of operations and financial condition will only be impacted by SFAS No. 154 if we implement changes in accounting principles that are addressed by the standard or have corrections of accounting errors.
     In June 2005, the FASB issued FSP No. FAS 143-1, “Accounting for Electronic Equipment Waste Obligations,” that provides guidance on how commercial users and producers of electronic equipment should recognize and measure asset retirement obligations associated with the European Directive 2002/96/EC on Waste Electrical and Electronic Equipment (“WEEE”). WEEE primarily impacts our operations in the United Kingdom. FSP No 143-1 is effective on the date that the United Kingdom adopts WEEE into law, which occurred on July 1, 2006. The adoption of FSP No. 143-1 did not have a material impact on the Company’s consolidated results of operations, financial position and cash flows for the three and nine months ended July 1, 2006.

Table of Contents

     In July 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an Interpretation of FASB Statement 109,” (FIN 48) that provides guidance on how a company should recognize, measure, present and disclose uncertain tax positions which a company has taken or expects to take. The effective date for FIN 48 is as of the beginning of fiscal years that start subsequent to December 15, 2006. The Company is currently assessing the impact of FIN 48 on its consolidated results of operations, financial position and cash flows.

OVERVIEW
     Plexus Corp. and its subsidiaries (together “Plexus,” the “Company,” or “we”) participate in the Electronic Manufacturing Services (“EMS”) industry. As a contract manufacturer, we provide product realization services to original equipment manufacturers, (“OEMs”), and other technology companies in a number of industry sectors that are described in our Form 10-K. We provide advanced electronics design, manufacturing and testing services to our customers with a focus on complex and global fulfillment solutions, high technology manufacturing and test services, and high reliability products. We offer our customers the ability to outsource all stages of product realization, including development and design, materials sourcing, procurement and management, prototyping and new product introduction, testing, manufacturing, product configuration, logistics and test/repair. We are increasingly providing fulfillment and logistic services to many of our customers. Direct Order Fulfillment (“DOF”) entails receiving orders from our customers that provide the final specifications required by the end customer. We then build to order and configure to order and deliver the product directly to the end customer. The DOF process relies on Enterprise Resource Planning (“ERP”) systems integrated with those of our customers to manage the overall supply chain from parts procurement through manufacturing and logistics. The following information should be read in conjunction with our consolidated financial statements included herein and the “Risk Factors” section beginning on page 29.
     Our customers include both industry-leading original equipment manufacturers and technology companies that have never manufactured products internally. As a result of our focus on serving industries that rely on advanced electronics technology, our business is influenced by technological trends such as the level and rate of development of telecommunications infrastructure and the expansion of networks and use of the Internet. In addition, the federal Food and Drug Administration’s approval of new medical devices and other governmental approval and regulatory processes can affect our business. Our business has also benefited from the trend to increased outsourcing by OEM’s.
     We provide most of our contract manufacturing services on a turnkey basis, which means that we procure some or all of the materials required for product assembly. We provide some services on a consignment basis, which means that the customer supplies the necessary materials, and we provide the labor and other services required for product assembly. Turnkey services require material procurement and warehousing, in addition to manufacturing,

and involve greater resource investments than consignment services. Other than certain test equipment used for internal manufacturing, we do not design or manufacture our own proprietary products.
EXECUTIVE SUMMARY
     Net sales for the three months ended July 1, 2006 increased by $83.7 million, or 26.7 percent, over the comparable prior-year period to $397.4 million. Net sales in each of our end-markets, or sectors, were higher in the current-year period except for wireless infrastructure. Net sales in the defense/security/aerospace sector, which benefited in the current-year period from production of a new program, exhibited the highest growth in both dollars and as a percentage.
     Net income for the three months ended July 1, 2006 was a record $25.1 million, and diluted earnings per share were $0.53, which compared favorably to a net loss of $(21.5) million, or $(0.50) per diluted share, in the prior-year period. The prior-year period included $27.6 million ($27.5 million after-tax) of primarily goodwill impairment ($26.9 million) and other restructuring charges which together were the equivalent of $0.66 per diluted share.
     Net sales for the nine months ended July 1, 2006 increased by $156.9 million, or 17.3 percent over the comparable prior-year period to $1.1 billion. Net sales for the nine months were higher than the prior-year period for all sectors except wireless infrastructure.
     Net income for the nine months ended July 1, 2006 was $57.4 million and diluted earnings per share were $1.24, which compared favorably to a net loss of $(22.9) million, or $(0.53) per diluted share, in the comparable prior-year period. The prior-year period included $39.2 million of, primarily, goodwill impairment costs ($26.9 million) and other restructuring charges.
     In addition to the positive effects of increased sales, earnings in both the three and nine months ended July 1, 2006 benefited not only from the absence of impairments of goodwill and other restructuring and asset impairment charges in the current periods, but also higher interest income earned on higher investment balances in a higher interest-rate environment and lower taxes than in the prior-year periods. Operationally, we expanded both gross and operating margins as more fully discussed below.
     Gross margins were 11.5 percent for the three months ended July 1, 2006, which compared favorably to 8.7 percent in the prior-year period. Gross margins were 10.7 percent for the nine months ended July 1, 2006 as compared to 8.3 percent in the prior-year period. Gross margins in both current-year periods benefited from the operating leverage gained on incremental revenues attained on a relatively fixed manufacturing cost structure, favorable changes in the customer and sector mix of revenues, and the continued application of “lean” manufacturing practices to enhance operational effectiveness. In addition, our second manufacturing facility in Penang, Malaysia (“Penang”), had commenced operations early in the prior fiscal year and operated at a loss for the nine months ended July 2, 2005. This second facility in Penang has been consistently profitable in both the three and nine months ended July 1, 2006 which has contributed to the year-over-year improvements for these current-year periods.
     Selling and administrative expenses were $21.6 million for the three months ended July 1, 2006, an increase of $2.3 million, or 11.7% over the prior-year period’s $19.3 million. The current-year period had increased salaries and benefits, reflecting wage increases and additional staffing, as well as higher accruals for variable incentive compensation and stock-based compensation. There was no stock-based compensation expense in the prior-year period.
     For the nine months ended July 1, 2006, selling and administrative expenses increased $1.5 million or 2.6% to $58.1 million. The current-year period had increased salaries and benefits, reflecting wage increases and additional staffing, as well as higher accruals for variable incentive compensation and stock-based compensation. There was no stock-based compensation expense in the prior-year period. The overall growth in selling and administrative expenses for the nine month period were moderated by lower bad debt expenses and lower outside professional fees associated with Section 404 of the Sarbanes Oxley Act.

     A further discussion of the fiscal third quarter’s financial performance by operating segment is presented below:
    United States: Net sales for the three months ended July 1, 2006 increased $63.6 million, or 27.5 percent, over the comparable prior-year period to $294.6 million. This growth reflected primarily increased net sales to several customers including Juniper Networks Inc. (“Juniper”), General Electric Corp. (“GE”) and a new customer within the defense sector. Operating income improved $14.9 million for the three months ended July 1, 2006, as compared to the prior-year period, primarily as a result of increased net sales on a relatively fixed manufacturing cost structure, favorable changes in customer mix and continued operational improvements achieved through “lean” manufacturing practices.
 
    Asia: Net sales for the three months ended July 1, 2006 increased $45.3 million, or 102.2 percent, over the prior-year period to $89.6 million as our facilities in this low-cost region became an increasingly important source for Printed Circuit Board Assemblies (PCBA’s). Operating income improved $5.2 million to $8.0 million for the three months ended July 1, 2006 as compared to the prior-year period. Earnings benefited from the incremental net sales and the turnaround from a loss to a profit at our second facility in Penang, which began production in the first quarter of fiscal 2005.
 
    Mexico: Net sales declined by $15.1 million, or 47.1 percent, to $16.9 million for the three months ended July 1, 2006, as compared to the prior-year period. The decline in revenues was principally related to the decision of a medical customer to transfer production back to a Plexus facility located in the United States as well as lower demand from other customers. The decrease in net sales resulted in an operating loss of $1.5 million for the three months ended July 1, 2006. In the comparable prior-year period, operating income was essentially break-even.
 
    Europe: Net sales declined by $2.9 million, or nearly 11.3 percent, to $23.0 million for the three months ended July 1, 2006, as compared to the prior-year period. The revenue decline was attributable to reduced demand from a medical customer in the current-year period. Lower operating income was primarily related to lower revenues.
     For our significant customers, we generally manufacture product in more than one location. For example, manufacturing for Juniper, our largest customer, occurs in the United States and Asia. Manufacturing for GE, a significant customer, takes place in the United States, Asia, and Mexico. See Note 8 in Notes to Condensed Consolidated Financial Statements for certain financial information regarding our operating segments, including a detail of net sales by operating segment.
     The effective income tax rates for the three and nine months ended July 1, 2006 were 1.3 percent and 1.0 percent, respectively, which compared favorably to the effective tax rates of (5.0) percent and (4.0) percent for the three and nine months ended July 2, 2005. The low current rate reflects increased income in tax jurisdictions where we currently do not pay tax: Asia and the United States. We enjoy tax holidays in both Malaysia and China, which extend through 2019 and 2013, respectively. In the United States, we have the benefit of the carryforward of net operating losses (NOLs) incurred in prior years to offset current taxable income. The deferred tax asset for these NOL carryforwards is offset by a full valuation allowance. The timing of the reversal of the valuation allowance will be determined by, among other things, the amount of taxable U.S. income and the amount of U.S. tax deductions generated by the exercises of nonqualified stock options or disqualifying dispositions of stock received under incentive stock options, which result in tax deductions, but not expense for financial statement purposes.
     We currently expect the annual effective tax rate for fiscal year 2006 to be approximately 1.0 percent. We estimate that our normalized world-wide effective tax rate for fiscal 2006 without this valuation allowance on our U.S. deferred tax assets would be approximately 25 percent.
     Our financial goals for the current fiscal year are to build on the prior year’s achievements and to focus on attaining industry-leading organic net sales growth and further improvements in operating income. We recently announced a revised growth target for net sales for full fiscal year 2006 of approximately 18.3 percent to 19.5 percent over fiscal 2005. Based on customer indications of expected demand and management estimates of new program wins, including the new program in our defense/security/aerospace sector, we currently expect net sales for

20


Table of Contents

the fourth fiscal quarter 2006 to be in the range of $390 million to $405 million; however, results will ultimately depend upon the actual level of customer orders. Assuming that net sales are in that range, we would currently expect to earn, before any restructuring and impairment costs, between $0.46 to $0.50 per diluted share.
     Our primary financial metric for measuring financial performance is after-tax return on capital employed (ROCE), which we anticipate will exceed in fiscal 2006 our estimated 15 percent weighted average cost of capital. We expect to achieve this improved metric through further expansion of operating margins and continued focus on improving working capital management to increase capital employed turnover. We define after-tax ROCE as tax-effected operating income, excluding unusual charges, divided by average capital employed, which is equity plus debt, less cash. Annualized after-tax ROCE for the fiscal third quarter was 34.0 percent, a substantial improvement over the 26.9 percent achieved in the fiscal second quarter.
RESULTS OF OPERATIONS
     Net sales. Net sales for the indicated periods were as follows (dollars in millions):
                                                                 
    Three months ended   Variance   Nine months ended   Variance
    July 1,   July 2,   Increase/   July 1,   July 2,   Increase/
    2006   2005   (Decrease)   2006   2005   (Decrease)
Net sales
  $ 397.4     $ 313.7     $ 83.7       27 %   $ 1,063.6     $ 906.7     $ 156.9       17 %
     The dollar increase in net sales for both the three and nine months ended July 1, 2006, reflects increased demand in all sectors except wireless infrastructure (see industry sector table below). The net sales growth was due to increased demand from several of our customers, including our largest customer, Juniper, and GE. In addition, the net sales growth in the defense/security/aerospace sector was driven by the addition of a new customer. This new customer represents a significant opportunity; the degree to which this customer relationship, as with all new customers, matures into a long-term relationship is not yet certain. Net sales in the wireless infrastructure sector were reduced due to lower end-customer demand for several accounts in this sector.
     Our net sales by industry sector for the indicated periods were as follows:
                                 
    Three months ended   Nine months ended
    July 1,   July 2,   July 1,   July 2,
Industry Sector   2006   2005   2006   2005

    14 %     5 %     9 %     4 %
     The percentages of net sales to customers representing 10 percent or more of net sales and net sales to our ten largest customers for the indicated periods were as follows:
                                 
    Three months ended   Nine months ended
    July 1,   July 2,   July 1,   July 2,

     Juniper recently announced the addition of another EMS provider. Although the Company expects to transfer certain programs currently manufactured at Plexus to this other EMS company, we also expect to win programs from Juniper that we currently do not manufacture. Accordingly, we expect that our revenues will be unaffected by Juniper’s decision to add a third EMS provider.
     Sales to the unnamed defense customer became significant to us in the third quarter of fiscal 2006. As a result of the nature of the project for that customer, Plexus expects that related orders and sales (if any) will vary significantly from period to period and are unlikely to result in predictable recurring revenue or revenue patterns across periods.
     Sales to our 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. We generally do not obtain firm, long-term purchase commitments from our customers. Customers’ forecasts can and do change as a result of changes in their end-market demand and other factors. Any material change in orders from these major accounts, or other customers, could materially affect our results of operations. In addition, as our percentage of sales to customers in a specific sector becomes larger relative to other sectors, we become increasingly dependent upon economic and business conditions affecting that sector.
     Gross profit. Gross profit and gross margins for the indicated periods were as follows (dollars in millions):
                                                                 
    Three months ended   Variance   Nine months ended   Variance
    July 1,   July 2,   Increase/   July 1,   July 2,   Increase/
    2006   2005   (Decrease)   2006   2005   (Decrease)
Gross Profit
  $ 45.5     $ 27.1     $ 18.4       67.7 %   $ 113.8     $ 75.0     $ 38.8       51.8 %
Gross Margin
    11.5 %     8.7 %                     10.7 %     8.3 %                
     For the three months ended July 1, 2006, gross profit and gross margin improvements were primarily due to increased net sales, favorable changes in the customer mix and improved operating efficiencies at several manufacturing locations. For the three months ended July 2, 2005, gross profit and gross margins were moderated by lower net sales and manufacturing inefficiencies at certain of our sites, particularly a break-even gross profit at our second facility in Penang which commenced manufacturing activities in the first quarter of fiscal 2005.
     For the nine months ended July 1, 2006, improved gross profit and gross margin were primarily due to increased net sales, favorable changes in the customer mix and improved operating performances at several manufacturing locations. For the nine months ended July 2, 2005, the gross profit and gross margin were unfavorably impacted by manufacturing inefficiencies at certain of our sites including: $0.9 million of net inventory adjustments at our Juarez, Mexico (“Juarez”) facility due to the loss of inventory from theft and other causes; $0.8 million of start-up costs at a new facility in Penang; and only a nominal profit at our Bothell site due to transition expenses and manufacturing inefficiencies related to the phase-out of that facility.
     Gross margins reflect a number of factors that can vary from period to period, including product and service mix, the level of new facility start-up costs, inefficiencies attendant the transition of new programs, product life cycles, sales volumes, price erosion within the electronics industry, overall capacity utilization, labor costs and efficiencies, the management of inventories, component pricing and shortages, the mix of turnkey and consignment business, fluctuations and timing of customer orders, changing demand for our customers’ products and competition within the electronics industry. Additionally, turnkey manufacturing involves the risk of inventory management, and a change in component costs can directly impact average selling prices, gross margins and net sales. Although we focus on expanding gross margins, there can be no assurance that gross margins will not decrease in future periods.
     Most of the research and development we conduct is paid for by our customers and is, therefore, included in both sales and cost of sales. We conduct our own 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.
     Selling and administrative expenses. Selling and administrative (S&A) expenses for the indicated periods were as follows (dollars in millions):

    Three months ended   Variance   Nine months ended   Variance
    July 1,   July 2,   Increase/   July 1,   July 2,   Increase/
    2006   2005   (Decrease)   2006   2005   (Decrease)
Sales and administrative expense (S&A)

Percent of net sales
    5.4 %     6.2 %                     5.5 %     6.2 %                
     The dollar increase in S&A for the three months ended July 1, 2006 was due to increased salaries and benefits, reflecting wage increases and additional staffing, as well as higher accruals for variable incentive compensation and stock-based compensation required to be recognized under SFAS No. 123(R) in fiscal 2006. Variable incentive compensation increased $2.1 million for the three months ended July 1, 2006 compared with the three months ended July 2, 2005. Stock-based compensation included in selling and administrative expenses was $0.5 million for the three months ended July 1, 2006. There was no stock-based compensation expense for the three months ended July 2, 2005. The increases were moderated by decreases to various other elements of expenses. The reduction in S&A as a percentage of net sales was attributable to the increase in net sales.
     The dollar increase in S&A for the nine months ended July 1, 2006 was also due to increased salaries and benefits, reflecting wage increases and additional staffing, as well as higher accruals for variable incentive compensation and stock-based compensation. Variable incentive compensation increased $3.5 million for the nine months ended July 1, 2006 as compared to the nine months ended July 2, 2005. Stock-based compensation included in selling and administrative expenses was $1.3 million for the nine months ended July 1, 2006. There was no stock-based compensation expense for the nine months ended July 2, 2005. The growth in selling and administrative expenses for the nine months ended July 1, 2006 was moderated by lower bad debt expense of $1.9 million and lower outside professional fees of $1.4 million associated with Section 404 of the Sarbanes Oxley Act of 2002 as compared to the nine months ended July 2, 2005. The reduction in S&A as a percentage of net sales was attributable to the increase in net sales.
     The Compensation Committee of the Plexus’ Board of Directors awarded approximately 0.7 million stock options at its meeting in May; this action increased the total expense for share-based compensation in the third quarter of fiscal 2006 to $0.7 million. We currently estimate our total share-based compensation expense to increase to $1.4 million or $0.03 per diluted share for the three months ended September 30, 2006.
     Restructuring and Impairment Actions: In the three and nine months ended July 1, 2006, we did not incur any additional net-restructuring charges. We did, however, incur pre-tax restructuring costs of $0.6 million and $1.0 million, respectively, related to our decisions initially to convert and ultimately to close our Maldon, England (“Maldon”) facility and to reduce our workforce in Juarez. The Maldon conversion and closure affects 120 employees. The Juarez workforce reduction affected 46 employees.
     For the three and nine months ended July 1, 2006, these restructuring costs noted above were offset by favorable adjustments of $0.6 million and $1.0 million, respectively, for reductions in lease obligations at three of our closed facilities near Bothell and Seattle, Washington (“Seattle”) and prior other restructuring accruals.
     For the three months and nine months ended July 2, 2005, we recorded $0.7 million and $12.3 million, respectively, of restructuring and asset impairment costs. For the three months ended July 2, 2005, these costs consisted of $0.3 million for the elimination of a corporate executive position, $0.2 million for additional severance and retention bonuses for one of the previously closed Seattle facilities and $0.2 million for a planned workforce reduction at Maldon related to the conversion of the facility from manufacturing to fulfillment, service and repair.
     For the nine months ended July 2, 2005, these costs consisted of $7.5 million of restructuring and impairment costs for the closure of the Seattle facility, $3.8 million for impairment of a shop floor data-collection system and $1.0 million of other restructuring and asset impairment costs at our corporate location, Juarez and Maldon.

     In addition to the restructuring and asset impairment costs noted above, for both the three and nine months ended July 2, 2005, we recorded goodwill impairment costs of $26.9 million, of which $16.1 million represented a partial impairment of goodwill associated with our United Kingdom operations and $10.8 million represented a complete impairment of goodwill associated with our Juarez operations.

     As of July 1, 2006, we have a remaining restructuring liability of approximately $7.7 million, all of which is expected to be paid in the next twelve months. See Note 7 and Note 11 in Notes to the Condensed Consolidated Financial Statements for further information on goodwill impairment and restructuring and asset impairment costs.
     Income taxes. Income taxes for the indicated periods were as follows (dollars in millions):
                                 
    Three months ended   Nine months ended
    July 1,   July 2,   July 1,   July 2,
    2006   2005   2006   2005
Income tax expense
  $ 0.3     $ 1.0     $ 0.6     $ 0.9  
Effective annual tax rate
    1.3 %     (5.0 )%     1.0 %     (4.0 )%
     The reduction in our effective tax rate for the three and nine months ended July 1, 2006, compared to the three and nine months ended July 2, 2005, was due to increased profits in Asia, where we currently enjoy tax holidays, and in the United States where the carry-forward of NOLs and the establishment in fiscal 2004 of a full-valuation allowance on deferred tax assets, result in no tax provision on U.S. income. As of July 1, 2006, we had a $44.3 million valuation allowance on U.S. deferred tax assets.
     In addition, U.S. GAAP requires us to periodically review our historical and projected levels of profitability in the United States, and we may be required to reduce the valuation allowance by crediting the tax provision for a portion of the remaining valuation allowance, which would have a beneficial impact on our effective tax rate. If the U.S. valuation allowance is reversed, our effective tax rate is expected to increase. We estimate that our normalized world-wide effective tax rate for fiscal 2006 without this valuation allowance would be approximately 25 percent.
     In July 2005, the Finance Act (the “Finance Act”) was enacted in the United Kingdom. The Finance Act limits the deduction of interest expense incurred in the United Kingdom when the corresponding interest income earned by the other party is not taxable to such party. We currently extend loans from a U.S. subsidiary to a subsidiary in the United Kingdom, which is affected by the Finance Act. The Finance Act affects interest expense incurred by the United Kingdom subsidiary on these loans arising or accrued after March 16, 2005. For the three and nine months ended July 1, 2006, we revised the estimated effect of the Finance Act on our United Kingdom interest deductions to approximately half of the interest expense recorded. This revision was based on continued discussions with the tax authorities in the United Kingdom. In fiscal 2005, we had provided income tax expense for the anticipated full effect of the Finance Act on the non-deductibility of this interest expense.

     The American Jobs Creation Act (the “Jobs Act”), enacted in the United States in 2004, includes a deduction of 85 percent of certain foreign earnings that are repatriated, as defined in the Jobs Act. We may elect to apply this provision to qualifying earnings repatriations made in fiscal 2006. During the three and nine months ended July 1, 2006 and July 2, 2005, we did not repatriate any qualified earnings pursuant to the Jobs Act. We have determined that $15 million to $30 million of existing foreign earnings meet the requirements of the Jobs Act. We are currently evaluating the repatriation of earnings in the amounts ranging from $0 to $15 million and currently estimate that a repatriation of earnings in this range would result in income tax of up to approximately $0.8 million.
LIQUIDITY AND CAPITAL RESOURCES
     Operating Activities. Cash flows provided by operating activities were $50.0 million for the nine months ended July 1, 2006, compared to cash flows provided by operating activities of 38.5 million for the nine months ended July 2, 2005. During the nine months ended July 1, 2006, cash provided by operating activities was primarily due to higher earnings (after adjusting for the non-cash effects of depreciation, amortization and stock-based compensation expense) and increased accounts payable, as a result of negotiating improved vendor terms. These sources of operating cash flows were partially offset by increased inventory and increased accounts receivable to support increased net sales.
     As of July 1, 2006, annualized days sales outstanding in accounts receivable remained at 50 days sales outstanding as compared to 50 days sales outstanding as of October 1, 2005. Annualized inventory turns remained at 6.4 turns for the three months ended July 1, 2006 as compared to 6.4 turns for fiscal 2005.
     Investing Activities. Cash flows used in investing activities totaled $45.9 million for the nine months ended July 1, 2006, which represented additions to property, plant and equipment of approximately $26.2 million as well as net purchases of short-term investments of $20 million. The additions to property, plant and equipment were primarily for our Asian operations as we continued to expand in that region. See Note 8 in Notes to the Condensed Consolidated Financial Statements for further information regarding our capital expenditures by operating segment.
     We utilize available cash as the primary means of financing our operating requirements. We currently estimate capital expenditures for fiscal 2006 to be approximately $30 million to $35 million, of which $26.2 million were made through the nine months ended July 1, 2006. This fiscal 2006 estimate excludes the capital expenditures to expand our current facility in Xiamen, China and to add a third facility in Penang, Malaysia which are expected to be incurred in fiscal 2007.
     Financing Activities. Cash flows provided by financing activities totaled $35.7 million for the nine months ended July 1, 2006, which primarily represented proceeds from the exercises of stock options.
     We believe that our projected cash flows from operations, available cash and short-term investments, the Secured Credit Facility, and leasing capabilities should be sufficient to meet our working capital and fixed capital requirements, as noted above, through fiscal 2006 and at least the early part of 2007. We currently do not anticipate having to use the Secured Credit Facility to finance this growth. As our financing needs increase, we may need to arrange additional debt or equity financing. We therefore evaluate and consider from time to time various financing alternatives to supplement our capital resources. However, we cannot be certain that we will be able to make any such arrangements on acceptable terms.
     We have not paid cash dividends in the past and do not anticipate paying them in the foreseeable future.
CONTRACTUAL OBLIGATIONS AND COMMITMENTS AND OFF-BALANCE SHEET ARRANGEMENTS
     Our disclosures regarding contractual obligations and commercial commitments are located in various parts of our regulatory filings.

DISCLOSURE ABOUT CRITICAL ACCOUNTING POLICIES
     Our accounting policies are disclosed in our 2005 Report on Form 10-K. During the three and nine months ended July 1, 2006, there were no material changes to these policies other than stock-based compensation as noted below. Our more critical accounting policies are as follows:
     Stock-Based Compensation — Effective October 2, 2005, we adopted Statement of Financial Accounting Standards No. 123 (R), “Share-Based Payment: An Amendment of Financial Accounting Standards Board Statements No. 123 and 95” (“SFAS No. 123(R)”), which revised SFAS No. 123, “Accounting for Stock-Based Compensation” and supersedes APB Opinion No. 25, “Accounting for Stock Issued to Employees”. SFAS No. 123(R) requires all share-based payments to employees, including grants of employee stock options, to be measured at fair value and expensed in the consolidated statement of operations over the service period (generally the vesting period) of the grant. Upon adoption, we transitioned to SFAS No. 123(R) using the modified prospective application, under which compensation expense is only recognized in the consolidated statements of operations beginning with the first period that SFAS No. 123(R) is effective and continuing to be expensed thereafter. Prior periods’ stock-based compensation expense is still presented on a pro-forma basis. We continue to use the Black-Scholes valuation model to value stock options. See Note 5 in Notes to Condensed Consolidated Financial Statements for further information.
     Impairment of Long-Lived Assets — We review 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 comparing its carrying value to the projected cash flows the property, plant and equipment are expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying value of the property exceeds its fair market value. The impairment analysis is based on significant assumptions made by management of future results,

26


Table of Contents

including revenue and cash flow projections. Circumstances that may lead to impairment of property, plant and equipment include reductions in future performance or industry demand and the restructuring of our operations.
     Intangible Assets — Under Statement of Financial Accounting Standards (“SFAS”) No. 142, “Goodwill and Other Intangible Assets,” beginning October 1, 2002, we no longer amortize goodwill and intangible assets with indefinite useful lives, but instead test those assets for impairment at least annually, with any related losses recognized in earnings when incurred. We perform goodwill impairment tests annually during the third quarter of each fiscal year and more frequently if an event or circumstance indicates that an impairment has occurred.
     We measure the recoverability of goodwill under the annual impairment test by comparing a reporting unit’s carrying amount, including goodwill, to a reporting unit’s estimated fair market value, which is primarily estimated using the present value of expected future cash flows, although market valuations may also be used. If the carrying amount of the reporting unit exceeds its fair value, goodwill is considered impaired and a second test is performed to measure the amount of impairment, if any. Circumstances that may lead to impairment of goodwill include, but are not limited to, the loss of a significant customer or customers and unforeseen reductions in customer demand, future operating performance or industry demand.
     Revenue — Net sales from manufacturing services are generally recognized upon shipment of the manufactured product to our customers, under contractual terms, which are generally FOB shipping point. Upon shipment, title transfers and the customer assumes risks and rewards of ownership of the product. Generally, there are no formal customer acceptance requirements or further obligations related to manufacturing services; if such requirements or obligations exist, then a sale is recognized at the time when such requirements are completed and such obligations fulfilled.
     Net sales from engineering design and development services, which are generally performed under contracts of twelve months or less duration, are recognized as costs are incurred utilizing the percentage-of-completion method; any losses are recognized when anticipated.
     Sales are recorded net of estimated returns of manufactured product based on management’s analysis of historical returns, current economic trends and changes in customer demand. Net sales also include amounts billed to customers for shipping and handling, if applicable. The corresponding shipping and handling costs are included in cost of sales.
     Restructuring Costs — From fiscal 2002 through fiscal 2006, we have recorded restructuring costs in response to reductions in sales and/or reduced capacity utilization. These restructuring costs included employee severance and benefit costs, and costs related to plant closings, including leased facilities that will be abandoned (and subleased, as applicable). Prior to January 1, 2003, severance and benefit costs were recorded in accordance with Emerging Issues Task Force (“EITF”) 94-3. The estimated lease loss was accrued for future remaining lease payments subsequent to abandonment, less any estimated sublease income.
     Subsequent to December 31, 2002, costs associated with a restructuring activity are recorded in compliance with SFAS No. 146, “Accounting for Costs Associated with Exit or Disposal Activities.” The timing and related recognition of severance and benefit costs, that are not presumed to be an ongoing benefit as defined in SFAS No. 146, depend on whether employees are required to render service until they are terminated in order to receive the termination benefits and, if so, whether employees will be retained to render service beyond a minimum retention period. During fiscal 2003, we concluded that we had a substantive severance plan based upon our past severance practices; therefore, we recorded certain severance and benefit costs in accordance with SFAS No. 112, “Employer’s Accounting for Postemployment Benefits,” which resulted in the recognition of a liability as the severance and benefit costs arose from an existing condition or situation and the payment was both probable and reasonably estimated.
     For leased facilities abandoned and expected to be subleased, a liability is recognized and measured at fair value for the future remaining lease payments subsequent to abandonment, less any estimated sublease income that could reasonably be obtained for the property. For contract termination costs, including costs that will continue to be incurred under a contract for its remaining term without economic benefit to the entity, a liability for future remaining payments under the contract is recognized and measured at its fair value.

27


Table of Contents

     The recognition of restructuring costs requires that we make certain judgments and estimates regarding the nature, timing and amount of costs associated with the planned exit activity. If our actual results in exiting these facilities differ from our estimates and assumptions, we may be required to revise the estimates of future liabilities, which would require the recognition of additional restructuring costs or the reduction of liabilities already recorded. At the end of each reporting period, we evaluate the remaining accrued balances to ensure that no excess accruals are retained, no additional accruals are required and the utilization of the provisions is for their intended purposes in accordance with developed exit plans.
     Income Taxes — Deferred income taxes are provided for differences between the bases of assets and liabilities for financial and income tax reporting purposes. We record a valuation allowance against deferred income tax assets when management believes it is more likely than not that some portion or all of the deferred income tax assets will not be realized. Realization of deferred income tax assets is dependent on our ability to generate sufficient future taxable income. Although we recorded a $36.8 million valuation allowance against all U.S. deferred income tax assets in fiscal 2004, we may be able to utilize these deferred income tax assets to offset future taxable income in the U.S. as was the case for the nine months of fiscal 2006.

RISK FACTORS
Our net sales and operating results may 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
 
    the level and timing of customer orders, particularly in light of the fact that some of our customers determine whether or not to 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 and demand for our customers’ products
 
    customers’ announcements of operating results and business conditions
 
    changes in the sales mix to our customers
 
    business conditions in our customers’ industries
 
    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
 
    local and regional events, such as holidays, that may affect our production levels
 
    credit ratings and securities analysts’ reports and
 
    changes in economic conditions and world events.
     The EMS industry is impacted by the state of the U.S. and global economies and world events. A slowdown in the U.S. or global economy, or in particular in the industries served by us, may result in our customers reducing their forecasts. The demand for our services could weaken, which in turn would impact our sales, capacity utilization, margins and financial results. Historically, we have seen periods, such as in fiscal 2003 and 2002, when our sales were adversely affected by a slowdown in the wireline/networking and wireless infrastructure sectors, as a result of reduced end-market demand and reduced availability of venture capital to fund existing and emerging technologies. These factors substantially influence our net sales and margins.
     Net sales to customers in the wireline/networking sector have increased significantly in absolute dollars, making us more dependent upon the performance of that industry and the economic and business conditions that affect it. In addition, net sales in the defense/security/aerospace sector have become increasingly important; net sales in this sector are particularly susceptible to significant period to period variations.
     Our quarterly and annual results are affected by the level and timing of customer orders, fluctuations in material costs and availabilities, and the degree of capacity utilization in the manufacturing process.
The majority of our net sales come from a relatively 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 net sales in recent periods. Our ten largest customers accounted for approximately 63 percent and 60 percent of our net sales for the three months ended July 1, 2006 and July 2, 2005, respectively. For the three months ended July 1, 2006, there were three customers each of which represented 10 percent or more of our net sales. Our principal customers have varied from period to period, 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 other major customers, could seriously harm our business.
Our customers may cancel their orders, change production quantities or delay production.

29


Table of Contents

     EMS companies must provide rapid product turnaround for their customers. We generally do not obtain firm, long-term purchase commitments from our customers. Customers may cancel their orders, change production quantities or delay production for a number of reasons that are beyond our control. The success of our customers’ products in the market and the strength of the markets themselves affect 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 addition, we make significant decisions, including determining the levels of business that we will seek and accept, production schedules, component procurement commitments, facility requirements, 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 reduce our ability to accurately estimate the future requirements of those customers. Because many of our costs and operating expenses are relatively fixed, a reduction in customer demand can harm our gross margins and operating results.
     Customers may require rapid increases in production, which can stress our resources and reduce operating margins. We may not have sufficient capacity at any given time to meet all of our customers’ demands or to meet the requirements of a specific program.
Failure to manage growth and contraction, if any, may seriously harm our business.
     Due to continued sales growth in fiscal 2006, we needed additional employees and production equipment to meet incremental demand. In fiscal 2004, we expanded of our operations in Penang, Malaysia and added many employees, principally in Asia. These actions resulted in additional costs to support our growth. We are currently evaluating further expansion alternatives in Asia, including a recently announced intention to double capacity in our existing Xiamen, China facility as well as adding a third facility in Penang, Malaysia. If we are unable to effectively manage the growth currently anticipated, our operating results could be adversely affected.
     Periods of contraction or reduced sales, such as the periods that occurred from fiscal 2001 through 2003, create challenges. We must determine whether facilities remain productive, determine whether staffing levels need to be reduced, and determine how to respond to changing levels of customer demand. While maintaining multiple facilities or higher levels of employment increases short-term costs, reductions in employment could impair our ability to respond to market improvements or to maintain customer relationships. Our decisions to reduce costs and capacity, such as the fiscal 2005 closure of our Bothell facility and the recently announced closure of our Maldon, England facility and the related reduction in the number of employees, can affect our expenses and, therefore, our short-term and long-term results.
     In addition, to meet our customers’ needs, or to achieve increased efficiencies, we sometimes require additional capacity in one location while reducing capacity in another. Since customers’ needs and market conditions can vary and change rapidly, we may find ourselves in a situation where we simultaneously experience the effects of contraction in one location while incurring the costs of expansion in another location, such as those noted above.
Expansion of our business and operations may negatively impact our business.
     We have announced our intentions to add a third facility in Malaysia as well as expand our existing facility in Xiamen, China. We may expand in geographical areas in which we currently operate or in new geographical areas within the United States or internationally. We may not be able to find suitable facilities on a timely basis or on terms satisfactory to us. Expansion of our operations involves numerous business risks, including:
    the inability to successfully integrate additional facilities or incremental 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
 
    creation of excess capacity, and the need to reduce capacity elsewhere if anticipated sales or opportunities do not materialize
 
    diversion of management’s attention from other business areas during the planning and implementation of expansions

Table of Contents

    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 sufficient customers or employees to support the expansion.
Operating in foreign countries exposes us to increased risks, including foreign currency risks.
     We have operations in China, Malaysia, Mexico and the United Kingdom. As noted above, we are considering a new manufacturing facility in Penang, Malaysia and have announced an expansion in China, and we may in the future expand further in these or into other international locations. We have limited experience in managing geographically dispersed operations. We also purchase a significant number of components manufactured in foreign countries. These international aspects of our operations subject us to the following risks that could materially impact our operating results:
    economic or political instability
 
    transportation delays or interruptions and other effects of the less-developed infrastructure in many countries
 
    foreign exchange rate fluctuations
 
    utilization of different systems and equipment
 
    difficulties in staffing and managing foreign personnel in diverse cultures and
 
    the effects of international political developments.
     In fiscal 2005, the Chinese and Malaysian governments revalued their currencies against the U.S. dollar. Both currencies had been relatively fixed to the U.S. dollar for the last several years, but both governments now appear to have adopted policies described as “managed floats” (that is, allowing their currencies to move in a tight range up or down from the previous day’s close). We do not currently “hedge” foreign currencies. As our Asian operations expand, our failure to adequately hedge foreign currency transactions and/or currency exposures associated with assets and liabilities denominated in non-functional currencies could adversely affect our financial condition, results of operations and cash flows.
     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. For example, our facility in Mexico operates under the Mexican Maquiladora program, which provides for reduced tariffs and eased import regulations; we could be adversely affected by changes in that program. Also, the Malaysian and Chinese subsidiaries currently receive favorable tax treatments from these governments which extend for approximately 13 years and 7 years, respectively, which may or may not be renewed.
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 continued ability to:
    retain 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

31


Table of Contents

implementation of new technologies and equipment may require significant expense or capital investment that 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.
We invest in technology to support our operations; developments may impair those assets.
     We are involved in a multi-year project to install a common ERP platform and associated information systems at most of our manufacturing sites. Our ERP platform is intended to augment our management information systems and includes various software systems to enhance and standardize our ability to globally translate information from production facilities into operational and financial information and create a consistent set of core business applications at our worldwide facilities. As of July 1, 2006, facilities representing a significant majority of our net sales are currently managed on the common ERP platform. We plan to extend the common ERP platform to our remaining sites over the next two years; however, the conversion timetable and project scope for our remaining sites are subject to change based upon our evolving needs.
Our manufacturing services involve inventory risk.
     Most of our contract manufacturing services are provided on a turnkey basis, under which we purchase some, or all, of the required materials. Accordingly, component price increases and inventory obsolescence could adversely affect our selling price, gross margins and operating results.
     In our turnkey operations, we need to order parts and supplies based on customer forecasts, which may be for a larger quantity of product than is included in the firm orders ultimately received from those customers. Customers’ cancellation or reduction of orders can result in additional expense to us. While most of our customer agreements include provisions that require customers to reimburse us for excess inventory specifically ordered to meet their forecasts, we may not actually be reimbursed or be able to collect on these obligations. In that case, we could have excess inventory and/or cancellation or return charges from our suppliers.
     In addition, we provide managed inventory programs for some of our key customers under which we hold and manage finished goods inventories. These managed inventory programs may result in higher finished goods inventory levels, further reduce our inventory turns and increase our financial exposure with such customers. Even though our customers generally have contractual obligations to purchase such inventories from us, we may remain subject to the risk of enforcing those obligations.
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 of the 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. At times, component shortages have been prevalent in our industry, and such shortages may be expected to recur from time to time. In some cases, supply shortages and delays in deliveries of particular components have resulted in curtailed or delayed production of assemblies, which contributed to an increase in our inventory levels. An increase in economic activity could result in shortages, if manufacturers of components do not adequately anticipate the increased orders and/or have previously excessively cut back their production capability in view of reduced activity in recent years. World events, such as terrorism, armed conflict and epidemics, could also affect supply chains. If we are unable to obtain sufficient components on a timely basis, we may experience manufacturing and shipping delays, which could harm relationships with our customers and reduce our sales.
     While most of our customer contracts permit quarterly or other periodic adjustments to pricing based on changes 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.

32


Table of Contents

Start-up costs and inefficiencies related to new or transferred programs can adversely affect our operating results.
     The management of labor and production capacity in connection with the establishment of new programs and new customer relationships, and the need to estimate required resources in advance of production can adversely affect our gross margins and operating margins. These factors are particularly evident in the early stages of the life cycle of new products and new programs or program transfers. The effects of these start-up costs and inefficiencies can also occur when we open new facilities, or when we transfer programs between locations. Customer needs, capacity utilization rates and/or increased demand may require that we expand certain facilities, or seek larger facilities in fiscal 2006, or future years. We are currently managing a number of new programs. Consequently, our exposure to these factors has increased. In addition, if any of these new programs or new customer relationships were terminated, our operating results could worsen, particularly in the short term.
     Although we try to minimize the potential losses arising from transitioning customer programs between Plexus facilities, there are inherent risks that such transitions can result in the disruption of programs and customer relationships.
We and our customers are subject to extensive government regulations.
     We are 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.
     Medical - Our medical device business, which represented approximately 25 percent of our net sales for the third quarter of fiscal 2006, is subject to substantial government regulation, primarily from the federal Food and Drug Administration (“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. Failure to comply with these regulations can result in, among other things, fines, injunctions, civil penalties, criminal prosecution, recall or seizure of devices, or total or partial suspension of production. 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. Violations may lead to penalties or shutdowns of a program or a facility. Failure or noncompliance could have an adverse effect on our reputation.
     In addition, our customers’ failure to comply with applicable regulations or legal requirements, or even allegations of such failures, could affect our sales to those customers.
     Defense - In recent periods, our net sales to the defense/security/aerospace sector have significantly increased. Companies that design and manufacture for this sector face governmental, security and other requirements that could materially affect their financial condition and results of operations. In addition, defense contracting can be subject to extensive procurement processes and other factors that can affect the timing and duration of contracts and orders. While those arrangements may result in a significant amount of net sales in a short period of time as they did in the third quarter of fiscal 2006, they may or may not result in continuing long-term relationships. Even in the case of continuing long-term relationships, orders in the defense sector can be episodic and vary significantly from period to period.
     Wireline/Wireless — The end-markets for most of our customers in the wireline/networking and wireless infrastructure sectors are subject to regulation by the Federal Communications Commission, as well as by various state and foreign government agencies. The policies of these agencies can directly affect both the near-term and long-term consumer and provider demand and profitability of the sector and therefore directly impact the demand for products that we manufacture.
     European Union - There are two European Union (“EU”) directives which could affect our business and results. The first of these is the Restriction of the use of Certain Hazardous Substances (“RoHS”). RoHS became

effective on July 1, 2006, and restricted within the EU the distribution of products containing certain substances, lead being the restricted substance most relevant to us. Although most of the EU member countries have not yet turned the mandates into legislation, it appears that we will be required to manufacture RoHS compliant products for customers intending to sell into the EU after the effective date. In addition, industry analysts anticipate that similar legislation in the U.S. and Asia will eventually follow.
     The second EU directive is the Waste Electrical and Electronic Equipment directive which requires a manufacturer or importer, at its own cost, to take back and recycle all of the products it either manufactured in or imported into the EU.
     Since both of these directives affect the worldwide electronics supply-chain, we expect to make collaborative efforts with our suppliers and customers to develop compliant processes and products. The cost of such efforts, the degree to which we will be expected to absorb such costs, the impact that the directive may have on product shipments, and our liability for non-compliant product was nominal.
Products we manufacture may contain design or manufacturing defects that could result in reduced demand for our services and liability claims against us.
     We manufacture products to our customers’ specifications that are highly complex and may at times contain design or manufacturing defects. 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 defect, 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 tarnished. In addition, these defects may result in liability claims against us. Even if customers are responsible for the defects, they may or may not be able to assume responsibility for any such costs or required payments to us, and we occasionally incur costs defending claims.
Our products are for the electronics industry, which produces technologically advanced products with relatively 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 that 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 reduced prices for our services.
     The electronics manufacturing services industry is highly competitive and has become more so as a result of excess capacity in the industry. We compete against numerous U.S. and foreign electronics manufacturing services providers with global operations, as well as those which operate on only a local or regional basis. In addition, current and prospective customers continually evaluate the merits of manufacturing products internally. Consolidations and other changes in the electronics manufacturing services industry result in a continually changing competitive landscape. The consolidation trend in the industry also results in larger and more geographically diverse competitors that may have significantly greater 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

Table of Contents

    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 which have greater direct buying power from component suppliers, distributors and raw material suppliers or which have lower cost structures. As a result, competitors may have a competitive advantage and obtain business from our customers. Our 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 depend on certain key personnel, and the loss of key personnel may harm our business.
     Our success depends in large part on the continued service of our key technical and management personnel, and on our ability to attract and retain qualified employees, particularly 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 significant, and the loss of key employees could harm our business.
Energy price increases may reduce our profits.
     We use some components made with petroleum-based materials. In addition, we use various energy sources transporting, producing and distributing products. Energy prices have increased significantly and are subject to further volatility caused by market fluctuations, supply and demand, currency fluctuation, production and transportation disruption, world events, and changes in governmental programs.
     Energy price increases raise both our material and operating costs. We may not be able to increase our prices enough to offset these increased costs. Increasing our prices also may reduce sales volume and profitability.
We may fail to successfully complete future acquisitions and may not successfully integrate acquired businesses, which could adversely affect our operating results.
     Although we have previously grown through acquisitions, our current focus is on pursuing organic growth opportunities. If we were to pursue future growth through acquisitions, however, this would 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
 
    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’s customer programs, including cancellation of current or anticipated programs
 
    loss of key employees of acquired businesses.
    Financial risks, such as the:
    use of cash resources, or incurrence of additional debt and related interest expenses
 
    dilutive effect of the issuance of additional equity securities
 
    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 our desired levels
 
    incurrence of large write-offs or write-downs
 
    impairment of goodwill and other intangible assets
 
    unforeseen liabilities of the acquired businesses.
We may fail to secure or maintain necessary financing.

     We maintain a Secured Credit Facility with a group of banks, which allows us to borrow up to $150 million depending upon compliance with related covenants and conditions. However, we cannot be certain that the Secured Credit Facility will provide all of the financing capacity that we will need in the future or that we will be able to amend the Secured Credit Facility or revise covenants, if necessary or appropriate in the future, to accommodate changes or developments in our business and operations.
     Our future success may depend on our ability to obtain additional financing and capital to support increased sales and our possible future growth. We may seek to raise capital by:
    issuing additional common stock or other equity securities
 
    issuing debt securities
 
    modifying existing credit facilities or obtaining new credit facilities
 
    a combination of these methods.
     We may not be able to obtain 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 shareholders’ ownership interests. Furthermore, any additional financing may have terms and conditions that adversely affect our business, such as restrictive financial or operating covenants, and our ability to meet any financing covenants will largely depend on our financial performance, which in turn will be subject to general economic conditions and financial, business and other factors.
Recently enacted changes in the securities laws and regulations have increased our costs.
     The Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”) has required changes in some of our corporate governance, securities disclosure and compliance practices. In response to the requirements of the Sarbanes-Oxley Act, the SEC and the NASDAQ Stock Market have promulgated rules on a variety of subjects. These developments may make it more difficult for us to attract and retain qualified members of our board of directors or qualified executive officers. Compliance with these new rules has increased our legal and accounting costs, most significantly in fiscal 2005, which was our first year of compliance. We expect our compliance costs to continue; however, absent significant changes in related rules (which we cannot assure), we anticipate these costs to be lower in fiscal 2006 and beyond as we become more efficient in our compliance processes.
If we reach other than an affirmative conclusion on the adequacy of our internal control over financial reporting as required by the Section 404 of the Sarbanes-Oxley Act, investors could lose confidence in the reliability of our financial statements, which could result in a decrease in the value of our common stock.
     As required by Section 404 of the Sarbanes-Oxley Act, the SEC adopted rules requiring public companies to include a report of management on the company’s internal control over financial reporting in their annual reports on Form 10-K; that report must contain an assessment by management of the effectiveness of our internal control over financial reporting. In addition, the independent registered public accounting firm auditing a company’s financial statements must attest to and report on both management’s assessment as to whether the company maintained effective internal control over financial reporting and on the effectiveness of the company’s internal control over financial reporting.
     In fiscal 2006, we are continuing our comprehensive efforts to comply with Section 404 of the Sarbanes-Oxley Act. If we are unable to complete our assessment in a timely manner or if we and/or our independent registered public accounting firm determines that there are material weaknesses regarding the design or operating effectiveness of our internal control over financial reporting, this could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements, which could cause the market price of our shares to decline.
Our operations could be negatively affected by an epidemic.
     We have a production facility in Xiamen, China, which is one of the countries that have been most at risk in the recent outbreak of avian flu. We also operate in Malaysia, which is in the area in which avian flu has spread. To

36


Table of Contents

the best of our knowledge, concerns about the spread of avian flu have not affected our employees or operations in China or Malaysia, nor have we experienced any disruption in our supply chain as a result of these concerns. However, our production in Asia and elsewhere could be severely impacted by an epidemic spread of avian flu or a similar widespread disease or epidemic. Our facilities could be closed by government authorities, some or all of our workforce could be unavailable due to quarantine, fear of contagion or other factors, and transportation or other elements of the infrastructure could be affected, leading to delays or loss of production.
     Concerns relating to avian flu are currently focused on Asia; however, avian flu or other outbreaks of disease or epidemics could similarly affect our other facilities. These health-related factors could also affect our suppliers and lead to a shortage of components. They could also lead to a reduction in end-customer demand.
The price of our common stock has been and may continue to be volatile.
     Our stock price has fluctuated in recent periods. The price of our common stock may fluctuate in response to a number of events and factors relating to us, 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 markets, along with share prices for technology companies in particular, have experienced extreme volatility, including weakness, that sometimes has 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. Our stock price and the stock price of many other technology companies remain below their peaks.
     Among other things, volatility and weakness in our stock price could mean that investors may not be able to sell their shares at or above the prices that they paid. Volatility and weakness could also impair our ability in the future to offer common stock or convertible securities as a source of additional capital and/or as consideration in the acquisition of other businesses.
ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
     We are exposed to market risk from changes in foreign exchange and interest rates. We selectively use financial instruments to reduce such risks.
Foreign Currency Risk
     We do not use derivative financial instruments for speculative purposes. Our policy is to selectively hedge our foreign currency denominated transactions in a manner that substantially offsets the effects of changes in foreign currency exchange rates. Historically, we have used foreign currency contracts to hedge only those currency exposures associated with certain assets and liabilities denominated in non-functional currencies. Corresponding gains and losses on the underlying transaction generally offset the gains and losses on these foreign currency hedges. Our international operations create potential foreign exchange risk. As of July 1, 2006, we had no foreign currency contracts outstanding.
     Our percentages of transactions denominated in currencies other than the U.S. dollar for the indicated periods were as follows:
                                 
    Three months ended   Nine months ended
    July 1,   July 2,   July 1,   July 2,
    2006   2005   2006   2005
Net Sales
    6 %     8 %     7 %     9 %
Total Costs
    10 %     13 %     12 %     13 %

Interest Rate Risk
     We have financial instruments, including cash equivalents and short-term investments, 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 highly rated securities, 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 secured credit facility. A 10 percent change in our weighted average interest rate on our average long-term borrowings would have had only a nominal impact on net interest expense for both the three months and nine months ended July 1, 2006 and July 2, 2005.
ITEM 4. CONTROLS AND PROCEDURES
     Disclosure Controls and Procedures: The Company maintains disclosure controls and procedures designed to ensure that the information the Company must disclose in its filings with the Securities and Exchange Commission is recorded, processed, summarized and reported on a timely basis. The Company’s principal executive officer and principal financial officer have reviewed and evaluated, with the participation of the Company’s management, the Company’s disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) as of the end of the period covered by this report (the “Evaluation Date”). Based on such evaluation, the chief executive officer and chief financial officer have concluded that, as of the Evaluation Date, the Company’s disclosure controls and procedures are effective in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by the Company in the reports the Company files or submits under the Exchange Act.
     Internal Control Over Financial Reporting: During the third quarter of fiscal 2006, there have been no changes to the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 13d-15(f) under the Exchange Act) that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
