PLEXUS CORP.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
FOR THE THREE MONTHS ENDED DECEMBER 31, 2005 AND JANUARY 1, 2005
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 December 31, 2005, and the results of operations for the three months ended December 31, 2005 and January 1, 2005, and the cash flows for the same three 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.
     Effective October 1, 2004, the Company’s fiscal year now ends on the Saturday closest to September 30 rather than on September 30, as was the case prior to fiscal 2005. In connection with the change to a fiscal year ending on the Saturday nearest September 30, the Company also changed the accounting for its interim periods to adopt a “4-4-5” accounting system for the “monthly” periods in each quarter. Each quarter will therefore end on a Saturday at the end of the 4-4-5 period. The accounting periods for the first quarter of fiscal 2006 and 2005 included 91 days and 93 days, respectively.
NOTE 2 — INVENTORIES
     The major classes of inventories are as follows (in thousands):
                 
    December 31,     October 1,  
    2005     2005  
Raw materials
  $ 122,956     $ 116,466  
Work-in-process
    29,608       30,282  
Finished goods
    31,215       33,350  
 
           
 
  $ 183,779     $ 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 December 31, 2005, 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 for both the three months ended December 31, 2005 and January 1, 2005.
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  
    December 31,     January 1,  
    2005     2005  
Basic and Diluted Earnings Per Share:
               
Net income
  $ 13,757     $ 3,022  
 
           
 
               
Basic weighted average common shares outstanding
    43,897       43,191  
Dilutive effect of stock options
    1,202       562  
 
           
Diluted weighted average shares outstanding
    45,099       43,753  
 
           
 
               
Earnings per share:
               
Basic
  $ 0.31     $ 0.07  
 
           
Diluted
  $ 0.31     $ 0.07  
 
           
     For the three months ended December 31, 2005 and January 1, 2005, stock options to purchase approximately 1.6 million and 3.4 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.
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 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, 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: In February 2005, the Company’s shareholders 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 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 0.8 million shares of the Company’s common stock from the approval date of the 2005 Plan through December 31, 2005.

     As a result of the adoption of SFAS No. 123(R), the Company recognized $0.8 million of compensation expense associated with stock options for the three months ended December 31, 2005. 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 months ended January 1, 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 assumption. The assumed risk-free rates were based on ten-year U.S. Treasury rates in effect at the time of grant. The expected option life represents the period of time that the options granted are expected to be outstanding and were based on historical experience.
     The weighted average fair value of options granted per share during the first fiscal quarter of fiscal 2006 and fiscal year 2005 is $10.32 and $5.72, respectively. The fair value of each option grant was estimated at the date of grant using the Black-Scholes option-pricing method with the following assumption ranges: 51 percent to 85 percent volatility, risk-free interest rates ranging from 2.43 percent to 4.55 percent, expected option life of 3.75 to 5.48 years, and no expected dividends.
     For the three months ended December 31, 2005, the total intrinsic value of stock options exercised was $2.8 million.
     As of December 31, 2005, there was $0.6 million of unrecognized compensation costs related to non-vested stock options that is expected to be recognized over a weighted average period of 1.17 years.
     Employee Stock Purchase Plans: In February 2005, the shareholders 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. No shares have been issued under the 2005 Purchase Plan as the Company had suspended employee stock purchases under this plan as a result of the accounting requirements of SFAS No. 123(R).
     The Board of Directors of the Company amended and reinstated the 2005 Purchase Plan. The 2005 Purchase Plan was amended 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 these amendments, the Company does not expect to record any compensation expense related to the 2005 Purchase Plan under SFAS No. 123(R).
NOTE 6 — 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 December 31, 2005, the Company had remaining goodwill of $6.8 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. In the third quarter of fiscal 2005, the Company recorded goodwill impairment of $26.9 million, of which $16.1 million represented a partial goodwill impairment associated with the Company’s operations in the United Kingdom and $10.8 million represented a full goodwill impairment associated with the Company’s operations in Juarez.
     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. 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. No assurances can be given that future impairment tests of the Company’s remaining goodwill will not result in additional impairment.
     The changes in the carrying amount of goodwill for the fiscal year ended October 1, 2005 and for the three months ended December 31, 2005 for the various business segments are as follows (amounts in thousands):

NOTE 7 — 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.

10


Table of Contents

     The Company has aggregated its operating segments into four reportable geographical segments: United States, Asia, Mexico and Europe. As of December 31, 2005, 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 revenues 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, general 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, general 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.
     Information about the Company’s four operating segments for the three months ended December 31, 2005, and January 1, 2005 were as follows (in thousands):

NOTE 8 — 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’ 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 excludes from 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 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 customer-supplied 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 includes 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 three months ended December 31, 2005, the Company incurred nominal warranty activity. As of December 31, 2005, the Company had recorded a $1.0 million warranty liability.
NOTE 9 — 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 10 — RESTRUCTURING AND IMPAIRMENT COSTS
     Fiscal 2005 restructuring and impairment costs: During the first quarter of fiscal 2005, the Company recorded pre-tax restructuring and impairment costs totaling $0.9 million of which $0.8 million was primarily associated with severance related to the planned closure of the Company’s Bothell, Washington (“Bothell”) engineering and manufacturing facility and $0.4 million represented additional impairment on the Company’s closed San Diego facility, partially offset by a $0.3 million reduction in lease obligations for one of the Company’s other closed facilities near Seattle, Washington (“Seattle”).
     During the remainder of fiscal 2005, the Company recorded additional pre-tax restructuring and impairment costs of $38.3 million associated with goodwill impairment, the closure of our Bothell facility, the write-off of the remaining elements of a shop floor data-collection system and other restructuring costs and adjustments to previously recognized restructuring actions. Listed below is a further explanation of these remaining elements of restructuring and impairment costs for fiscal 2005.
     Bothell Facility Closure. During the second and third quarters of fiscal 2005, the Company incurred additional restructuring costs associated with the closure of the Bothell facility. The Company transferred most of the key customer programs from the Bothell facility to other Plexus locations, primarily in the United States. This restructuring reduced the Company’s capacity and affected approximately 160 employees. The Company completed the closure of the Bothell facility during fiscal 2005. In addition to $0.8 million of severance costs recorded in the first quarter, as noted above, the Company incurred additional restructuring and impairment costs associated with the Bothell facility closure of approximately $6.7 million, which consisted of $6.2 million for the facility lease, $0.3 million for employee retention costs and $0.2 million of other associated costs. The liability for the facility lease was 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.
     Shop Floor Data-Collection System Impairment. In the second quarter of fiscal 2005, the Company recorded a $3.8 million impairment of the remaining elements of a shop floor data-collection system. The Company had previously recorded a $1.7 million impairment related to the shop floor data-collection system in fiscal 2004 when it determined that certain elements would not be utilized in any capacity. During the first quarter of fiscal 2005, the Company extended a maintenance and support agreement for the data-collection system through July 2005 to provide it additional time to evaluate the remaining elements of the system. Based on the Company’s evaluation, it determined that the shop floor data-collection system was impaired. The Company determined that it would abandon deployment of these remaining elements of the shop floor data-collection system because the anticipated business benefits could not be realized.
     Goodwill 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 operations in the United Kingdom and $10.8 million represented a full impairment of goodwill associated with operations in Juarez. As of December 31, 2005, the United Kingdom operations have remaining goodwill of $6.8 million. (See Note 6 — Goodwill and Other Intangible Assets).
     Other Restructuring Costs. During the second and third quarters of fiscal 2005, the Company also recorded the following other restructuring and impairment costs:
      $0.5 million, which consisted of $0.4 million associated with a workforce reduction and $0.1 million of asset impairments at the Juarez facility was recorded in the second quarter of fiscal 2005. The Juarez workforce reduction affected approximately 50 employees;
      $0.3 million for severance associated with the elimination of a corporate executive position was recorded in the third quarter of fiscal 2005;
      $0.2 million for a planned workforce reduction at the Maldon, England (“Maldon”) facility was recorded in the third quarter of fiscal 2005. As noted above, a significant customer in the United Kingdom intends to transfer future production from the United Kingdom to a lower-cost location by the end of fiscal 2006. As a result,

the Company plans to consolidate its Maldon manufacturing operations into Kelso, Scotland and to focus the Maldon facility on fulfillment and service and repair;
      $0.3 million of other restructuring costs.
     Adjustments to Provisions: During fiscal 2005, the Company also recorded certain adjustments to previously recognized restructuring and impairment costs:
      a $0.4 million reduction in an accrual for lease obligations associated with a warehouse located in Neenah, Wisconsin (“Neenah”). The Neenah warehouse was previously abandoned as part of a fiscal 2003 restructuring action; however, the Company reactivated use of the warehouse in the second quarter of fiscal 2005;
     The table below summarizes the Company’s accrued restructuring liabilities as of December 31, 2005 (in thousands):

     As of December 31, 2005, we expect to pay $3.6 million of the remaining severance and lease obligation costs in the next twelve months. The remaining accrued lease obligation costs of $7.1 million are expected to be paid through October 2011.
NOTE 11 — SUBSEQUENT EVENT
     The Company issued a press release on January 25, 2006 and reported net income of $12.6 million, or fully diluted earnings per share of $0.28, for the fiscal first quarter. Subsequently, the Company received $1.2 million in cash for an account receivable that had been fully reserved when the Company issued its January 25, 2006 financial results. As a result of this subsequent event, the Company reduced both its allowance for doubtful accounts and the related bad debt expense by $1.2 million for the three months ended December 31, 2005. As a result, net income increased $1.2 million, or an increase of fully diluted earnings per share of $0.03.
NOTE 12 — NEW ACCOUNTING PRONOUNCEMENTS
     In November 2004, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 151, “Inventory Costs, an amendment of ARB No. 43, Chapter 4” (“SFAS 151”), which requires that abnormal amounts of idle facility expense, freight, handling costs, and wasted material be recognized as current period charges. In addition, this statement requires that allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. We were required to adopt this statement in the first quarter of our fiscal 2006. Our adoption of SFAS 151 did not have a significant impact on our financial position, results of operations or cash flows.
     In December 2004, 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

Table of Contents

repatriation of foreign earnings for purposes of applying SFAS No. 109. We are presently reviewing this new 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 December 2004, the FASB issued SFAS No. 153, “Exchanges of Nonmonetary Assets — An Amendment of APB No. 29,” which eliminates the exception for nonmonetary exchanges of similar productive assets and replaces it with a general exception for exchanges of nonmonetary assets that do not have commercial substance. Under SFAS 153, if a nonmonetary exchange of similar productive assets meets a commercial-substance criterion and the fair value is determinable, the transaction must be accounted for at fair value resulting in recognition of any gain or loss. We were required to adopt SFAS No. 153 for nonmonetary asset exchanges occurring in the first quarter of 2006. Our adoption of SFAS No. 153 did not have a significant effect on our financial position, results of operations or cash flows.
     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 are required to adopt FIN 47 by the end of fiscal 2006. We are currently assessing the impact of FIN 47 on our results of operations and financial condition.
     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 is anticipated sometime in fiscal 2006. We are currently assessing the potential impact of FSP No. 143-1 on our financial condition, results of operations and cash flows.

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 26.
     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 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 first quarter of fiscal 2006 increased by $40.8 million, or 14.2 percent, over the comparable prior year period to $328.3 million. Net income for the first quarter of fiscal 2006 increased to $13.8 million from $3.0 million, and fully diluted earnings per share increased to $0.31 from $0.07. Net income for the first quarter of fiscal 2006 included approximately $0.8 million, equivalent to $0.02 per fully diluted share, for our initial recognition of equity-based incentive compensation expense under Statement of Financial Accounting Standards No. 123 (R), “Shared-Based Payment: An Amendment of Financial Accounting Standards Board Statements No. 123 and 95” (“SFAS No. 123(R)”). (See Note 5 in Notes to Condensed Consolidated Financial Statements). Net income for the first quarter of fiscal 2005 included approximately $0.8 million, or $0.02 per fully diluted share, of restructuring and impairment costs.
     Net income for the first quarter of fiscal 2006 benefited from higher net sales and operational improvements, discussed more fully below, and the absence of restructuring and impairment costs as well as from a lower effective tax rate: the tax rate in the current quarter was 2 percent versus an 8 percent effective tax rate in the comparable prior year period. The lower 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 2014 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. For the rest of fiscal 2006, we currently expect the effective tax rate to not exceed 2 percent.
     Earnings benefited from higher net sales and the attendant improvements in productivity within each operating segment:
    United States: Net sales for the first quarter of fiscal 2006 increased $14.9 million, or 6.7 percent, over the prior year period to $237.9 million. Growth in the United States was moderated by the closure in the prior year of the Bothell, Washington (“Bothell”) site for manufacturing and engineering, which was primarily oriented to serving customers in the Medical sector, as not all programs were transitioned to other Plexus’ sites. Additionally, certain programs were transferred from various other sites in the United States to lower-cost sites in Asia. Operating income in the United States improved primarily as a result of higher revenues and operational efficiencies.
 
    Asia: Net sales in the first quarter of fiscal 2006 increased $25.3 million, or 77 percent, over the prior year to $58.1 million. As a result of the higher net sales and the absence of the start-up costs incurred in the prior year period at a new facility in Penang, Malaysia, operating income improved from essentially a breakeven in the prior year to $4.4 million. We continue to expand our capabilities in Asia, and additional infrastructure costs for Information Technology and business development have, and will, moderate growth in operating profit in this segment.
 
    Mexico: Net sales in the first quarter of fiscal 2006 of $26.1 million were $6.2 million, or 19 percent, lower than in the prior year period mainly as a result of the transfer of certain medical programs to sites in the United States; the operating loss in this segment was moderated to ($0.3) million from the prior year’s loss of ($1.6 million), which included a net unfavorable adjustment of $0.9 million arising from certain inventory material control issues.
 
    Europe: Net sales in this segment increased $2.1 million, or 9 percent, due to a ramp to volume production for a new program and improved net sales in a Defense sector program that had been reduced in the prior year period to help rebalance that customer’s inventory position. Overall net sales increased despite the absence in the current quarter of any significant revenues from a medical customer pending resolution of a formal investigation of that customer by a regulatory agency in the United Kingdom. Operating income improved by nearly $1 million to $2.2 million on higher revenues and improved productivity.
     For our significant customers, we generally manufacture product in more than one location. Net sales to Juniper, our largest customer, occur in our operating segments in the United States and Asia. Net sales to GE, a significant customer, occur in our operating segments in the United States, Asia, and Mexico. See Note 7 in Notes to

Table of Contents

Condensed Consolidated Financial Statements for certain financial information regarding our operating segments, including a detail of net sales by operating segment.
     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 reaffirmed our previously announced net sales growth target for full fiscal 2006 of approximately 15 percent to 18 percent over fiscal 2005. Based on customer indications of expected demand and management estimates of new program wins, we currently expect second fiscal quarter 2006 net sales to be in the range of $330 million to $345 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 between $0.31 to $0.36 per fully diluted share, excluding any restructuring or impairment costs.
     Our primary financial metric for measuring financial performance is after-tax return on capital employed (ROCE), which we currently anticipate will exceed our estimated 15 percent weighted average cost of capital in fiscal 2006. We expect to achieve this improved metric by further expansion of operating margins and continued focus on improving working capital management to increase capital employed turnover. We define ROCE as operating income, excluding unusual charges, divided by average capital employed, which is equity plus debt less cash.
RESULTS OF OPERATIONS
     Net sales. Net sales for the indicated periods were as follows (dollars in millions):
                                 
    Three months ended        
    December 31,     January 1,        
    2005     2005     Increase  
Net Sales
  $ 328.3     $ 287.5     $ 40.8       14 %
     Our net sales increase of 14 percent reflected increased demand in most sectors, but particularly in the wireline/networking and industrial/commercial sectors, where there were program wins from both new and existing customers.
     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 first fiscal quarter of 2006 and 2005 were as follows:
                 
    Three months ended  
    December 31,     January 1,  
    2005     2005  
Juniper
    22 %     20 %
GE
    15 %     11 %
Top 10 customers
    61 %     60 %
     Sales to our largest customers may vary from time to time depending on the size and timing of customer program commencements, terminations, delays, modifications and transitions. We remain dependent on continued sales to our significant customers, and we generally do not obtain firm, long-term purchase commitments from our customers. Customers’ forecasts can and do change as a result of changes in their end-market demands 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 net sales to customers in a specific sector becomes larger relative to other sectors, we will become increasingly dependent upon economic and business conditions affecting that sector.

Table of Contents

     Our net sales by industry sector for the indicated periods were as follows:
                 
    Three months ended  
    December 31,     January 1,  
Sector   2005     2005  
Wireline/Networking
    42 %     39 %
Wireless Infrastructure
    8 %     11 %
Medical
    28 %     31 %
Industrial/Commercial
    17 %     14 %
Defense/Security/Aerospace
    5 %     5 %
     The net sales growth in the wireline/networking sector was primarily associated with Juniper, our largest customer. Net sales growth in the industrial/commercial sectors was due to increased sales volumes with three customers. In the remaining sectors, net sales in dollars were essentially flat with the prior year period.
     Gross profit. Gross profit and gross margins for the indicated periods were as follows (dollars in millions):
                                 
    Three months ended        
    December 31,     January 1,        
    2005     2005     Increase  
Gross Profit
  $ 31.3     $ 22.3     $ 9.0       40 %
Gross Margin
    9.5 %     7.8 %                
     The improvement in gross profit was primarily due to higher net sales and improved operating performance in each of our operating segments arising primarily from lean manufacturing and other cost-reduction initiatives. In the first quarter of fiscal 2005, gross profits and gross margin improvements were moderated by the following factors:
    manufacturing inefficiencies and material control issues in our Juarez facility
 
    start-up costs at a new facility in Penang, Malaysia which commenced manufacturing activities in the first quarter of fiscal 2005.
     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.
     Operating expenses. Selling and administrative expenses for the indicated periods were as follows (dollars in millions):
                                 
    Three months ended        
    December 31,     January 1,        
    2005     2005     Decrease  
Selling and administrative expense (S&A)
  $ 17.2     $ 18.1       ($0.9 )     (5 %)
Percent of net sales
    5.2 %     6.3 %                

20


Table of Contents

     The dollar decrease in S&A was due to a combination of factors including; a decrease in bad debt expense of $0.6 million (see Note 11 in Notes to Condensed Consolidated Financial Statements), reduced spending on our internal and external resources to comply with Section 404 of the Sarbanes-Oxley Act of 2002, partially offset by our initial recognition of stock-based compensation expense under SFAS No. 123(R) of approximately $0.6 million in the first quarter of fiscal 2006. The significant reduction in S&A as a percent of net sales was primarily due to the 14 percent increase in net sales over the comparable prior year period.
     The Compensation Committee of Plexus’ Board of Directors has typically awarded stock options at its meeting in May, which action would increase the expense for share-based compensation in the fiscal third and fourth quarters of fiscal 2006.
     Restructuring Actions: In the first quarter of fiscal 2006, we did not incur any restructuring charges. In the first quarter of fiscal 2005, we recorded pre-tax restructuring and impairment costs totaling $0.9 million of which $0.8 million was primarily associated with severance related to the planned closure of our Bothell engineering and manufacturing facility and $0.4 million represented additional impairment on our closed San Diego facility, partially offset by a $0.3 million reduction in lease obligations for one of our other closed facilities near Seattle, Washington (“Seattle”).
     Pre-tax restructuring charges for the indicated periods are summarized as follows (in thousands):
                 
    Three months ended  
    December 31,     January 1,  
    2005     2005  
Severance costs
  $     $ 732  
Lease exit costs and other
          28  
Adjustment to asset impairment arising from the sublease of a closed facility
          432  
Adjustment to lease exit costs arising from a sublease of a closed facility
          (308 )
 
           
Total restructuring costs
  $     $ 884  
 
           
     During the remainder of fiscal 2005, we recorded additional pre-tax restructuring and impairment costs of $38.3 million associated with goodwill impairment, the closure of our Bothell facility, the write-off of the remaining elements of a shop floor data-collection system and other restructuring costs and adjustments to previously recognized restructuring actions.
     As of December 31, 2005, we have a remaining restructuring liability of approximately $10.7 million, of which $3.6 million is expected to be paid in next twelve months. The remaining $7.1 million is expected to be paid through October 2011. See Note 10 in Notes to the Condensed Consolidated Financial Statements for further information on restructuring and impairment costs.
     Income taxes. Income taxes for the indicated periods were as follows (dollars in millions):
                 
    Three months ended  
    December 31,     January 1,  
    2005     2005  
Income tax expense
  $ 0.3     $ 0.3  
Effective tax rate
    2 %     8 %
     The reduction in our effective tax rate in the first quarter of fiscal 2006, compared to the prior year period, 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.

21


Table of Contents

     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 reinstate the then-remaining deferred tax asset by crediting the then-remaining valuation allowance to the tax provision, which would create a one-time beneficial impact on our effective tax rate. Once the U.S. valuation allowance is reversed, our effective tax rate is expected to increase.
     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 is effective for interest expense incurred by the United Kingdom subsidiary on these loans arising or accrued after March 16, 2005. For the first quarter of fiscal 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.
     In October 2004, the American Jobs Creation Act (the “Jobs Act”) was enacted in the United States. The Jobs Act 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 first quarter of fiscal 2006 and fiscal 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 will 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 $17.4 million for the first quarter of fiscal 2006, compared to cash flows used in operating activities of $4.5 million for the first quarter of fiscal 2005. During the first quarter of fiscal 2006, cash flows provided by operating activities were primarily provided by increased accounts payable, as a result of improved vendor terms, and earnings (after adjusting for the non-cash effects of depreciation and amortization expense); these positive cash flow effects were offset, in part, by higher accounts receivable and inventory in support of anticipated higher net sales in the next fiscal quarter.
     As of December 31, 2005, days sales outstanding in accounts receivable were 50 days, the same as the 50 days sales outstanding as of October 1, 2005.
     Our inventory turns increased to 6.5 turns for the first quarter of fiscal 2006 from 6.4 turns for fiscal 2005.
     Investing Activities. Cash flows used in investing activities totaled $9.5 million for the first quarter of fiscal 2006 and were for additions to property, plant and equipment, primarily in our Asian operations as we continue to expand in that region. See Note 7 in Notes to the Condensed Consolidated Financial Statements for further information regarding our first quarter 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 in the range of $30 million to $35 million, of which $9.5 million were made during the first quarter of fiscal 2006.
     Financing Activities. Cash flows provided by financing activities totaled $4.0 million for the first fiscal quarter of fiscal 2006, which primarily represented the proceeds from the exercise of stock options and the net proceeds from borrowings and repayments on debt and capital lease obligations.
     Our secured revolving credit facility, as amended (the “Secured Credit Facility”), allows us to borrow up to $150 million from a group of banks. Borrowing under the Secured Credit Facility may be either through revolving or swing loans or letters of credit. The Secured Credit Facility is secured by substantially all of our domestic working capital assets and a pledge of 65 percent of the stock of each of our foreign subsidiaries. Interest on borrowings varies with our total leverage ratio, as defined in our credit agreement, and begins at the Prime rate (as defined) or LIBOR plus 1.5 percent. We also are required to pay an annual commitment fee of 0.5 percent of the

22


Table of Contents

unused credit commitment. The Secured Credit Facility matures on October 31, 2007 and includes certain financial covenants customary in agreements of this type. These covenants include a minimum adjusted EBITDA, maximum outstanding borrowings (not to exceed 2.5 times adjusted EBITDA for the trailing four quarters) and a minimum tangible net worth, all as defined in the agreement. The Secured Credit Facility includes a definition of adjusted EBITDA to exclude any impairment charges that may arise from time to time in our assessment of our goodwill. We are allowed to repurchase common shares and pay cash dividends as long as we remain in compliance with the various covenants.
     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. Although our net sales growth anticipated for fiscal 2006 will increase our working capital needs, we currently do not anticipate having to use our 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. We anticipate using any earnings to support our business.

(4)   — As of December 31, 2005, other long-term obligations not on the balance sheet consist of a salary commitment to an executive officer of the Company under an employment agreement. We did not have, and were not subject to, any lines of credit, standby letters of credit, guarantees, standby repurchase obligations, or other commercial commitments.
DISCLOSURE ABOUT CRITICAL ACCOUNTING POLICIES
     Our accounting policies are disclosed in our 2005 Report on Form 10-K. During the first quarter of fiscal 2006, there were no material changes to these policies. 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.
     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 of future results made by management, including revenue and cash flow projections. Circumstances that may lead to impairment of property, plant and equipment include decreases 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.

24


Table of Contents

     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 2005, 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 and for leased facilities that were abandoned and subleased. The estimated lease loss was accrued for future remaining lease payments subsequent to abandonment, less any estimated sublease income. As of December 31, 2005, we have one significant Seattle facility remaining which has not yet been subleased. If we were able to sublease the remaining Seattle facility, we would record an adjustment to restructuring costs.
     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 recording 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 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.
     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, requiring the recording 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 purpose 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 in the first quarter 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 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 our 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
 
    health and disease issues which could affect local, regional or global markets
 
    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 and increased as a percentage of total net sales, making us more dependent upon the performance of that industry and the economic and business conditions that affect it.
     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 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 largest customer for the first quarter of fiscal 2006 represented 22 percent of our net sales, while net sales to our largest customer in the first quarter of fiscal 2005 represented 20 percent of net sales. One other customer for the first quarter of fiscal 2006 and fiscal 2005 represented 15 percent and 11 percent of our net sales, respectively. We had no other customers that represented 10 percent or more of net sales in either of the periods. Sales to our ten largest customers have represented a majority of our net sales in recent periods. Our ten largest customers accounted for approximately 61 percent and 60 percent of our net sales for the first quarter of fiscal 2006 and fiscal 2005, respectively. 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, such as the fiscal 2005 goodwill impairment associated with our operations in the United Kingdom that resulted from a significant customer’s announced intention to transfer future production from our United Kingdom facility to a lower-cost location.

Our customers may cancel their orders, change production quantities or delay production.
     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 the first quarter of fiscal 2006, we needed additional employees and production equipment to meet incremental demand. In fiscal 2004, we began the expansion 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. If we are unable to effectively manage the growth currently anticipated for the remainder of fiscal 2006, 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 later 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 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.
Expansion of our business and operations may negatively impact our business.
     We have expanded our presence in Malaysia and may further expand our operations thereby establishing or acquiring other facilities or by expanding capacity in our current facilities. We may expand both in geographical areas in which we currently operate and in new geographical areas within the United States and internationally. We may not be able to find suitable facilities on a timely basis or on terms satisfactory to us. Expansion of our operations involves numerous business risks, including:
    the inability to successfully integrate additional facilities or capacity and to realize anticipated synergies, economies of scale or other value
 
    additional fixed costs which may not be fully absorbed by the new business
 
    difficulties in the timing of expansions, including delays in the implementation of construction and manufacturing plans
 
    creation of excess capacity, and the need to reduce capacity elsewhere if anticipated sales or opportunities do not materialize

Table of Contents

    diversion of management’s attention from other business areas during the planning and implementation of expansions
 
    strain placed on our operational, financial, management, technical and information systems and resources
 
    disruption in manufacturing operations
 
    incurrence of significant costs and expenses
 
    inability to locate 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 expanded our operations in Malaysia, and we may in the future expand 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). 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 9 years and 8 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

28


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 December 31, 2005, 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 with Malaysia and China in fiscal 2006; however, the conversion timetable and project scope for our remaining sites is subject to change based upon our evolving needs.
     As of December 31, 2005, overall ERP investments included in net property, plant and equipment totaled $21.5 million and we anticipate incurring approximately $4.2 million of capital expenditures for the common ERP platform for the remainder of fiscal 2006. Changes in our technology needs may affect the utility of our common ERP platform and require additional expenditures in the future.
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.

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. 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 of 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.
     Our medical device business, which represented approximately 28 percent of our net sales for the first quarter of fiscal 2006, is subject to substantial government regulation, primarily from the federal 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.
     In addition, 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 becomes effective on July 1, 2006, and restricts 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 indicate that similar legislation in the U.S. and Asia will eventually follow.
     The second EU directive is the Waste Electrical and Electronic Equipment directive, now effective, under which a manufacturer or importer is required, 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 is not yet known, but could have a material effect on our operations and results.

     In recent periods, our sales related to the defense/security/aerospace sector have begun to increase. 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.
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.
Our business in the wireline/networking and wireless infrastructure sectors could be slowed by further government regulation of the communications industry.
     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.
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
 
    adapt more quickly to changes in customer requirements

31


Table of Contents

    devote greater resources to the development, promotion and sale of their services
 
    be better positioned to compete on price for their services.
     We may be operating at a cost disadvantage compared to manufacturers who have greater direct buying power from component suppliers, distributors and raw material suppliers or who have lower cost structures. As a result, competitors may 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.
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 current outbreak of avian flu. We also operate in Malaysia, which is in the area in which avian flu has spread. To 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 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.
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

32


Table of Contents

    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 sure 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 new 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 the company’s 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 will continue a comprehensive effort 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.

Table of Contents

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 Stock Market, 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 December 31, 2005, 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  
    December 31, 2005     January 1, 2005  
Net Sales
    8 %     8 %
Total Costs
    13 %     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 in the first quarter of fiscal 2006 and fiscal 2005, respectively.

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, such officers have concluded that, as of the Evaluation Date, the Company’s disclosure controls and procedures are effective in bringing to their attention on a timely basis material information relating to the Company required to be included in the Company’s periodic filings under the Exchange Act.
     Internal Control Over Financial Reporting: During the first quarter of fiscal 2006, there have been no changes to the Company’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
