NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

FOR THE THREE AND SIX MONTHS ENDED APRIL 2, 2011 AND APRIL 3, 2010

NOTE 1 - BASIS OF PRESENTATION AND ACCOUNTING POLICIES

Basis of Presentation

              The accompanying condensed consolidated financial statements included herein have been prepared by Plexus Corp. and its subsidiaries (“Plexus” or the “Company”) without audit and pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). In the opinion of the Company, the accompanying condensed consolidated financial statements reflect all adjustments, which include normal recurring adjustments necessary for the fair statement of the consolidated financial position of the Company as of April 2, 2011, and the results of operations for the three and six months ended April 2, 2011 and April 3, 2010, and the cash flows for the same six 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’s 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 consolidated financial statements and notes thereto included in the Company’s 2010 Annual Report on Form 10-K.

              The Company’s fiscal year ends on the Saturday closest to September 30. The Company also uses a “4-4-5” weekly accounting system for the interim periods in each quarter. Each quarter therefore ends on a Saturday at the end of the 4-4-5 period. Periodically, an additional week must be added to the fiscal year to re-align with the Saturday closest to September 30. The accounting periods for the three and six months ended April 2, 2011 and April 3, 2010 each included 91 days and 182 days, respectively.

              In the fiscal first quarter of 2011, we completed our migration to a regional reporting structure. This change included establishing regional targets for various financial metrics, delegating additional authority to the regions to manage their business, and changing our related internal reporting. Given this change to regional reporting and management, as well as in the information used by management for assessing performance and allocating Company resources, we modified our reporting segments. Prior to fiscal 2011, the Company’s reportable segments consisted of the United States, Asia, Europe and Mexico. During the fiscal first quarter of 2011, we combined our United States and Mexico segments into the “Americas” (AMER) segment and renamed our Asia segment “Asia Pacific” (APAC) and our Europe segment “Europe, Middle East and Africa” (EMEA) to better represent our long-range regional focus. As a result, we have conformed all prior period segment presentations to be consistent with our current reportable segments. See Note 10 - Business Segment, Geographic and Major Customer Information for further information.

Cash and Cash Equivalents:

              Cash and cash equivalents include highly liquid investments with original maturities of three months or less at the time of purchase.

Fair Value of Financial Instruments

              The Company holds financial instruments consisting of cash and cash equivalents, accounts receivable, accounts payable, debt, and capital lease obligations. The carrying value of cash and cash equivalents, accounts receivable, accounts payable and capital lease obligations as reported in the condensed consolidated financial statements approximate fair value. Accounts receivable were reflected at net realizable value based on anticipated losses due to potentially uncollectible balances. Anticipated losses were based on management’s analysis of historical losses and changes in customers’ credit status. The fair value of the Company’s term loan debt was $98.6 million and $105.2 million as of April 2, 2011 and October 2, 2010, respectively. The carrying value of the Company’s term loan debt was $105.0 million and $112.5 million as of April 2, 2011 and October 2, 2010, respectively. The Company uses quoted market prices when available or discounted cash flows to calculate the fair value of its term loan debt.

              Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (or exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The accounting guidance establishes a fair value hierarchy based on three levels of inputs that may be used to measure fair value. The input levels are:

              Level 1: Quoted (observable) market prices in active markets for identical assets or liabilities.

              Level 2: Inputs other than Level 1 that are observable, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

              Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the asset or liability.

NOTE 2 - INVENTORIES

              Inventories are stated at the lower of cost (on a first-in, first-out basis) or market value. The stated cost is comprised of direct materials, labor, and overhead. The major classes of inventories, net of applicable lower of cost or market write-downs, were as follows (in thousands):

		April 2,				October 2,
		2011				2010
Raw materials		$	365,735			$	365,883
Work-in-process			50,054				56,036
Finished goods			83,693				70,511
		$	499,482			$	492,430

              Per contractual terms, customer deposits are received by the Company to offset obsolete and excess inventory risks. The total amount of customer deposits related to inventory and included within current liabilities on the accompanying Condensed Consolidated Balance Sheets as of April 2, 2011 and October 2, 2010 was $28.1 million and $25.8 million, respectively.

NOTE 3 - PROPERTY, PLANT AND EQUIPMENT

              Property, plant and equipment consisted of the following categories (in thousands):

		April 2,				October 2,
		2011				2010
Land, buildings and improvements		$	151,997			$	138,230

Less: accumulated depreciation			(279,632	)			(258,907	)
		$	237,435			$	235,714

NOTE 4 - LONG-TERM DEBT

              On April 4, 2008, the Company entered into its credit agreement (the “Credit Facility”) with a group of banks which allows the Company to borrow $150 million in term loans and $100 million in revolving loans. The $150 million in term loans was immediately funded and the $100 million revolving credit facility is currently available. The Credit Facility is unsecured and the revolving credit facility may be increased by an additional $100

million (the “accordion feature”) if the Company has not previously terminated all or any portion of the Credit Facility, there is no event of default existing under the Credit Facility and both the Company and the administrative agent consent to the increase. The Credit Facility expires on April 4, 2013. Borrowings under the Credit Facility may be either through term loans or revolving or swing loans or letter of credit obligations. As of April 2, 2011, the Company has term loan borrowings of $105.0 million outstanding and no revolving borrowings under the Credit Facility.

              The Credit Facility contains certain financial covenants, which include a maximum total leverage ratio, maximum value of fixed rentals and operating lease obligations, a minimum interest coverage ratio and a minimum net worth test, all as defined in the agreement. As of April 2, 2011, the Company was in compliance with all debt covenants. If the Company incurs an event of default, as defined in the Credit Facility (including any failure to comply with a financial covenant), the group of banks has the right to terminate the remaining Credit Facility and all other obligations, and demand immediate repayment of all outstanding sums (principal and accrued interest). The interest rate on the borrowing varies depending upon the Company’s then-current total leverage ratio; as of April 2, 2011, the Company could elect to pay interest at a defined base rate or the LIBOR rate plus 1.00%. Rates would increase upon negative changes in specified Company financial metrics and would decrease upon reduction in the current total leverage ratio to no less than LIBOR plus 1.00%. The Company is also required to pay an annual commitment fee on the unused credit commitment based on its leverage ratio; the current fee is 0.25%. Unless the accordion feature is exercised, this fee applies only to the initial $100 million of availability (excluding the $150 million of term borrowings). Origination fees and expenses associated with the Credit Facility totaled approximately $1.3 million and have been deferred. These origination fees and expenses are being amortized over the five-year term of the Credit Facility. Equal quarterly principal repayments of the term loan of $3.75 million per quarter began on June 30, 2008 and end on April 4, 2013, with a balloon repayment of $75.0 million.

              The Credit Facility allows for the future payment of cash dividends or the future repurchases of shares provided that no event of default (including any failure to comply with a financial covenant) is existing at the time of, or would be caused by, a dividend payment or a share repurchase.

              Interest expense related to the commitment fee and amortization of deferred origination fees and expenses for the Credit Facility totaled approximately $0.2 million for both the three months ended April 2, 2011 and April 3, 2010, and $0.3 million for both the six months ended April 2, 2011 and April 3, 2010.

              See Note 15 — Subsequent Event for information on the Company’s fixed rate debt issued on April 21, 2011.

NOTE 5 - DERIVATIVES AND FAIR VALUE MEASUREMENTS

              All derivatives are recognized in the accompanying Condensed Consolidated Balance Sheets at their estimated fair value. On the date a derivative contract is entered into, the Company designates the derivative as a hedge of a recognized asset or liability (a “fair value” hedge), a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability (a “cash flow” hedge), or a hedge of the net investment in a foreign operation. The Company currently has cash flow hedges related to variable rate debt and forecasted foreign currency payments. The Company does not enter into derivatives for speculative purposes. Changes in the fair value of the derivatives that qualify as cash flow hedges are recorded in “Accumulated other comprehensive income” in the accompanying Condensed Consolidated Balance Sheets until earnings are affected by the variability of the cash flows.

              During the fiscal second quarter of 2011, the Company entered into forward exchange contracts to fix the exchange rates on foreign currency cash used to pay for capital expenditures related to the construction of our fourth facility in Malaysia. As of April 2, 2011, the total notional value of the forward contracts was $18.1 million and the total fair value of these forward contracts was $0.2 million.

              During the fiscal second quarter of 2011, the Company entered into two separate treasury rate lock hedge contracts to hedge the variability of the fixed interest rate on the then forecasted issuance of $175 million of fixed rate debt using a treasury lock transaction. As of April 2, 2011, the two contracts had a combined notional amount of $150 million and a fair value of $1.4 million. The fixed interest rates for each of these contracts are 2.77% and 2.72%, respectively. On April 4, 2011, the Company entered into a final treasury rate lock hedge transaction for the

remaining $25 million of exposure at a rate of 2.88%. On April 8, 2011, when the fixed interest rate for the debt issuance was determined, all three treasury rate lock contracts were settled and the Company received proceeds of $2.3 million, which will be amortized over the seven year term of the related debt. See Note 15 — Subsequent Event for more information about the Company’s fixed rate debt issuance on April 21, 2011.

              In June 2008, the Company entered into three interest rate swap contracts related to the $150 million in term loans under the Credit Facility that had an initial total notional value of $150 million and mature on April 4, 2013. These interest rate swap contracts will pay the Company variable interest at the three month LIBOR rate, and the Company will pay the counterparties a fixed interest rate. The fixed interest rates for each of these contracts are 4.415%, 4.490% and 4.435%, respectively. These interest rate swap contracts were entered into to convert $150 million of the variable rate term loan under the Credit Facility into fixed rate debt. Based on the terms of the interest rate swap contracts and the underlying debt, these interest rate contracts were determined to be effective, and thus qualify as a cash flow hedge. As such, any changes in the fair value of these interest rate swaps are recorded in “Accumulated other comprehensive income” on the accompanying Condensed Consolidated Balance Sheets until earnings are affected by the variability of cash flows. The total fair value of these interest rate swap contracts was $6.6 million as of April 2, 2011. As of April 2, 2011, the total remaining combined notional amount of the Company’s three interest rate swaps was $105.0 million.

              The Company’s Malaysian operations have entered into forward exchange contracts on a rolling basis with a total notional value of $38.5 million as of April 2, 2011. These forward contracts will fix the exchange rates on foreign currency cash used to pay a portion of local currency expenses. The changes in the fair value of the forward contracts are recorded in “Accumulated other comprehensive income” on the accompanying Condensed Consolidated Balance Sheets until earnings are affected by the variability of cash flows. The total fair value of these forward contracts was $1.9 million as of April 2, 2011.

The following table lists the fair values of the Company’s derivatives as of April 2, 2011, by input level as defined above:

				Fair Value Measurements Using Input Levels:
				(in thousands)
				Level 1					Level 2					Level 3					Total
Derivatives
	Interest rate swaps		$		-			$		6,562			$		-				$	6,562
	Foreign currency forward contracts		$		-			$		2,130			$		-				$	2,130
	Treasury rate locks		$		-			$		1,412			$		-				$	1,412

              The fair value of interest rate swaps and foreign currency forward contracts is determined using a market approach which includes obtaining directly or indirectly observable values from third parties active in the relevant markets. The primary input in the fair value of the interest rate swaps is the relevant LIBOR forward curve. Inputs in the fair value of the foreign currency forward contracts include prevailing forward and spot prices for currency and interest rate forward curves. The primary input in the fair value of the treasury rate locks is the treasury rate yield.

NOTE 6 - 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								Six Months Ended
		April 2,				April 3,				April 2,				April 3,
		2011				2010				2011				2010
Basic and Diluted Earnings Per Share:
Net income		$	23,860			$	20,714			$	48,893			$	38,558
Basic weighted average common shares outstanding			39,927				39,885				40,197				39,736
Dilutive effect of stock options outstanding			732				876				737				793
Diluted weighted average shares outstanding			40,659				40,761				40,934				40,529
Earnings per share:
Basic		$	0.60			$	0.52			$	1.22			$	0.97
Diluted		$	0.59			$	0.51			$	1.19			$	0.95

              For the three and six months ended April 2, 2011, stock options and stock-settled stock appreciation rights (“SARs”) related to approximately 1.3 million and 1.2 million shares, respectively, were outstanding but were not included in the computation of diluted earnings per share because the options’ and stock-settled SARs’ exercise prices were greater than the average market price of the common shares and, therefore, their effect would be antidilutive.

              For the three and six months ended April 3, 2010, stock options and stock-settled SARs related to approximately 1.0 million and 1.2 million shares, respectively, were outstanding but were not included in the computation of diluted earnings per share because the options’ and stock-settled SARs’ exercise prices were greater than the average market price of the common shares and, therefore, their effect would be antidilutive.

NOTE 7 - STOCK-BASED COMPENSATION

              The Company recognized $3.1 million and $5.5 million of compensation expense associated with stock-based awards for the three and six months ended April 2, 2011, respectively, and $2.8 million and $4.7 million for the three and six months ended April 3, 2010, respectively.

              The Company continues to use the Black-Scholes valuation model to determine the fair value of stock options and stock-settled SARs. The Company uses the fair value at the date of grant to value restricted stock units and unrestricted stock awards. The Company recognizes stock-based compensation expense over the stock-based awards’ vesting period.

NOTE 8 - SHAREHOLDERS’ EQUITY

              On February 16, 2011, as previously announced, the Company’s Board of Directors approved a new share repurchase program that authorizes the Company to repurchase up to $200 million of common stock. As of April 2, 2011, the Company has repurchased 2.7 million shares for approximately $83.4 million, at an average price of $30.57 per share. These shares were recorded as treasury stock. As of April 2, 2011, the Company had a commitment of approximately $10.2 million related to the purchase of 0.3 million shares, which were purchased before April 2, 2011, but settled after the end of the fiscal second quarter.

NOTE 9 - INCOME TAXES

              Income tax expense for the three and six months ended April 2, 2011 was $0.7 million and $1.5 million, respectively. The effective tax rates for both the three and six months ended April 2, 2011 were 3 percent. As demonstrated in recent quarters, the Company’s tax rate can vary during the year based on the mix of forecasted earnings by tax jurisdiction. The Company currently benefits from reduced taxes in the Asia Pacific segment due to tax holidays.

              Income tax expense for the three and six months ended April 3, 2010 was $0.6 million and $0.8 million, respectively. The effective tax rates for the three and six months ended April 3, 2010 were 3 percent and 2 percent, respectively.

              As of April 2, 2011, there was no material change in the amounts recorded for uncertain tax positions. The Company recognizes accrued interest and penalties related to uncertain tax positions in income tax expense. The amount of interest and penalties recorded for both the three and six months ended April 2, 2011 and April 3, 2010 was not material.

              It is reasonably possible that a number of uncertain tax positions related to federal and state tax positions may be settled within the next 12 months. Settlement of these matters is not expected to have a material effect on the Company’s consolidated results of operations, financial position and cash flows.

              The Company maintains valuation allowances when it is more likely than not that all or a portion of a deferred tax asset will not be realized. Despite recent losses in the United States tax jurisdiction, the Company has concluded that it continues to be more likely than not that the net U.S. deferred tax assets will be realized, and no valuation allowance is warranted. Our net deferred income taxes as of April 2, 2011, reflect a $1.6 million valuation allowance against certain state deferred income taxes and a remaining valuation allowance of $1.0 million related to state tax deductions associated with stock-based compensation. If the United States operations continue to generate taxable losses, there may be a need to provide additional valuation allowance on our net United States deferred tax assets.

NOTE 10 - BUSINESS SEGMENT, GEOGRAPHIC AND MAJOR CUSTOMER INFORMATION

              Reportable 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.

              In the fiscal first quarter of 2011, we completed our migration to a regional reporting structure, and as a result, modified our reportable segments. See Note 1 — Basis of Presentation and Accounting Policies for further information.

              The Company uses an internal management reporting system, which provides important financial data to evaluate performance and allocate the Company’s resources on a regional basis. Net sales for segments are attributed to the region in which the product is manufactured or service is performed. The services provided, manufacturing processes used, class of customers serviced and order fulfillment processes used are similar and generally interchangeable across the segments. A segment’s performance is evaluated based upon its operating income (loss). A segment’s operating income (loss) includes its net sales less cost of sales and selling and administrative expenses, but excludes corporate and other costs, interest expense, other income (loss), and income taxes. Corporate and other costs primarily represent corporate selling and administrative expenses, and restructuring and impairment costs, if any. 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 three reportable segments for the three and six months ended April 2, 2011 and April 3, 2010 were as follows (in thousands):

              No other customers accounted for 10 percent or more of net sales in either period.

NOTE 11 - 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, misconduct, breach of contract, or infringement of third party intellectual property rights. Certain agreements have extended broader indemnification, and while most agreements have contractual limits, some do not. However, the Company generally does not provide for such indemnities and seeks indemnification from its customers for damages or liabilities arising out of the Company’s adherence to customers’ specifications or designs or use of materials furnished, or directed to be used, by its customers. The Company does not believe its obligations under such indemnities are material.

              In the normal course of business, the Company also provides its customers a limited warranty covering workmanship, and in some cases materials, on products manufactured by the Company. Such warranty generally provides that products will be free from defects in the Company’s workmanship and meet mutually agreed-upon specifications for periods generally ranging from 12 months to 24 months. If a product fails to comply with the Company’s limited warranty, the Company’s obligation is generally limited to correcting, at its expense, any defect by repairing or replacing such defective product. The Company’s warranty generally excludes defects resulting from faulty customer-supplied components, design defects or damage caused by any party or cause other than the Company.

              The Company provides for an estimate of costs that may be incurred under its limited warranty at the time product revenue is recognized and establishes additional reserves for specifically identified product issues. These costs primarily include labor and materials, as necessary, associated with repair or replacement and are included in the Company’s accompanying Condensed Consolidated Balance Sheets in other current accrued liabilities. The primary factors that affect the Company’s warranty liability include the value and 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.

              Below is a table summarizing the activity related to the Company’s limited warranty liability for fiscal 2010 and for the six months ended April 2, 2011 (in thousands):

Limited warranty liability, as of October 3, 2009		$	4,470
Accruals for warranties issued during the period			557
Settlements (in cash or in kind) during the period			(972	)
Limited warranty liability, as of October 2, 2010			4,055
Accruals for warranties issued during the period			108
Settlements (in cash or in kind) during the period			(316	)
Limited warranty liability, as of April 2, 2011		$	3,847

NOTE 12 - LITIGATION

              In the fiscal fourth quarter of 2010, the Company determined it would incur up to approximately $1.1 million relating to non-conforming inventory received from a supplier. The Company reached a settlement with the supplier during the fiscal first quarter of 2011 for $0.9 million, of which $0.8 million of recovery has been received and recorded in selling and administrative expenses as of April 2, 2011.

              In the fiscal first quarter of 2010, the Company received settlement funds of approximately $3.2 million related to a court case in which the Company was a plaintiff. The settlement related to prior purchases of inventory and therefore was recorded in cost of sales.

              The Company is party to certain other 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 consolidated financial position, results of operations or cash flows.

NOTE 13 - CONTINGENCIES

              We were notified in April 2009 by U.S. Customs and Border Protection (“CBP”) of its intention to conduct a customary Focused Assessment of our import activities during fiscal 2008 and of our processes and procedures to comply with U.S. Customs laws and regulations. We recorded an accrual in Other Accrued current liabilities at the time the amount became estimable and probable, which was not material to the financial statements. During September 2010, the Company reported errors relating to import trade activity from July 2004 to the date of Plexus’ report. The Company is currently awaiting final determination of CBP duties and fees. Plexus has agreed that it will implement improved processes and procedures and review these corrective measures with CBP. At this time, we do not believe that any deficiencies in processes or controls or unanticipated costs, unpaid duties or penalties associated with this matter will have a material adverse effect on Plexus or the Company’s consolidated financial position, results of operations or cash flows.

NOTE 14 - NEW ACCOUNTING PRONOUNCEMENTS

              In October 2009, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance for Multiple-Deliverable Revenue Arrangements, which establishes a selling price hierarchy for determining the selling price of a deliverable, replaces the term “fair value” in the revenue allocation guidance with “selling price,” eliminates the residual method of allocation by requiring that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method and requires that a vendor determine its best estimate of selling price in a manner that is consistent with that used to determine the price to sell the deliverable on a stand-alone basis. The Company adopted this guidance beginning October 3, 2010, and the adoption did not have a material effect on our financial position, results of operations, or cash flows.

              In June 2009, the FASB issued an amendment to the accounting and disclosure requirements for the consolidation of variable interest entities (“VIEs”). The elimination of the concept of a qualifying special-purpose entity (“QSPE”) removes the exception from applying the consolidation guidance within this amendment. This amendment requires an enterprise to perform a qualitative analysis when determining whether or not it must consolidate a VIE. The amendment also requires an enterprise to continuously reassess whether it must consolidate a VIE. Additionally, the amendment requires enhanced disclosures about an enterprise’s involvement with VIEs and any significant change in risk exposure due to that involvement, as well as how its involvement with VIEs impacts the enterprise’s financial statements. Finally, an enterprise will be required to disclose significant judgments and assumptions used to determine whether or not to consolidate a VIE. The Company adopted this amendment beginning October 3, 2010, and the adoption did not have a material effect on our financial position, results of operations, or cash flows.

NOTE 15 - SUBSEQUENT EVENT

              On April 21, 2011, the Company entered into a Note Purchase Agreement (the “Agreement”) with certain institutional investors related to $175 million in principal amount of 5.20% Senior Notes, due on June 15, 2018 (the “Notes”). The Company issued $100 million in principal amount of the Notes on April 21, 2011, and it will issue the remaining $75 million on June 15, 2011. The Agreement includes operational and financial covenants which include a maximum total leverage ratio, a minimum interest coverage ratio and restrictions on additional indebtedness, liens and dispositions, all as defined in the Agreement. The Notes are unsecured and rank at least equally and ratably in point and security with the other unsecured and unsubordinated financing facilities of the Company. Our effective interest rate on the Notes after the treasury rate lock agreement discussed in Note 5 — Derivatives and Fair Value Measurements will be 4.97%.

OVERVIEW

              The following information should be read in conjunction with our condensed consolidated financial statements included herein and the “Risk Factors” section in Part I, Item 1A of our annual report on Form 10-K for the fiscal year ended October 2, 2010.

              Plexus Corp. and its subsidiaries (together “Plexus,” the “Company,” or “we”) participate in the Electronic Manufacturing Services (“EMS”) industry. We deliver optimized Product Realization solutions through a unique Product Realization Value Stream service model. This customer focused service model seamlessly integrates innovative product design, customized supply chain solutions, uniquely configured “focused factory” manufacturing, global end-market fulfillment and after-market services to deliver comprehensive end-to-end solutions for customers. We provide these services to original equipment manufacturers (“OEMs”) and other technology companies in the wireline/networking, wireless infrastructure, medical, industrial/commercial and defense/security/aerospace market sectors. We provide advanced product development, manufacturing and testing services to our customers with a focus on the mid-to-lower-volume, higher complexity segment of the EMS market. Our customers’ products typically require exceptional production and supply-chain flexibility, necessitating an optimized demand-pull-based manufacturing and supply chain solution across an integrated global platform. Many of our customers’ products require complex configuration management and direct order fulfillment to their customers across the globe. In such cases we provide global logistics management and after-market service and repair. Our customers’ products may have stringent requirements for quality, reliability and regulatory compliance. We offer our customers the ability to outsource all phases of product realization, including product specifications; development, design and design verification; regulatory compliance support; prototyping and new product introduction; manufacturing test equipment development; materials sourcing, procurement and supply-chain management; product assembly/manufacturing, configuration and test; order fulfillment, logistics and service/repair.

              Plexus is passionate about its goal to be the best EMS company in the world at providing services for customers that have mid-to-lower-volume requirements and a higher complexity of products. We have tailored our engineering services, manufacturing operations, supply-chain management, workforce, business intelligence systems, financial goals and metrics specifically to support these types of programs. Our flexible manufacturing facilities and processes are designed to accommodate customers with multiple product-lines and configurations as well as unique quality and regulatory requirements. Each of these customers is supported by a multi-disciplinary customer team and one or more uniquely configured “focus factories” supported by a supply-chain and logistics solution specifically designed to meet the flexibility and responsiveness required to support that customer’s fulfillment requirements.

              Our go-to-market strategy is also tailored to our target market sectors and business strategy. We have business development and customer management teams that are dedicated to each of the five sectors we serve. These teams are accountable for understanding the sector participants, technology, unique quality and regulatory requirements and longer-term trends in these sectors. Further, these teams help set our strategy for growth in these sectors with a particular focus on expanding the services and value-add that we provide to our current customers while strategically targeting select new customers to add to our portfolio.

              Our financial model is aligned with our business strategy, with our primary focus to earn a return on invested capital (“ROIC”) 500 basis points in excess of our weighted average cost of capital (“WACC”). We review our internal calculation of WACC annually, and at the end of fiscal 2010 reduced our estimated WACC to 13.5%. The smaller volumes, flexibility requirements and fulfillment needs of our customers typically result in greater investments in inventory than many of our competitors, particularly those that provide EMS services for high-volume, less complex products with less stringent requirements (such as consumer electronics). In addition, our cost structure relative to these peers includes higher investments in selling and administrative costs as a percentage of sales to support our sector-based go-to-market strategy, smaller program sizes, flexibility, and complex quality and regulatory compliance requirements. By exercising discipline to generate a ROIC in excess of our WACC, our goal is to ensure that Plexus creates a value proposition for our shareholders as well as our customers.

              Our customers include both industry-leading OEMs and other technology companies that have never manufactured products internally. As a result of our focus on serving market sectors that rely on advanced electronics technology, our business is influenced by technological trends such as the level and rate of development of telecommunications infrastructure, the expansion of networks and use of the Internet. In addition, the federal Food and Drug Administration’s approval of new medical devices, defense procurement practices and other governmental approval and regulatory processes can affect our business. Our business has also benefited from the trend to increased outsourcing by OEMs.

              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 and software used for internal operations, we do not design or manufacture our own proprietary products.

EXECUTIVE SUMMARY

              As a consequence of the Company’s use of a “4-4-5” weekly accounting system, periodically an additional week must be added to the fiscal year to re-align with a fiscal year end at the Saturday closest to September 30. The accounting periods for the three and six months ended April 2, 2011 and April 3, 2010 each included 91 days and 182 days, respectively.

              In the fiscal first quarter of 2011, we completed our migration to a regional reporting structure. This change included establishing regional targets for various financial metrics, delegating additional authority to the regions to manage their business, and changing our related internal reporting. Given this change to regional reporting and management, as well as in the information used by management for assessing performance and allocating Company resources, we modified our reporting segments. Prior to fiscal 2011, the Company’s reportable segments consisted of the United States, Asia, Europe and Mexico. During the fiscal first quarter of 2011, we combined our United States and Mexico segments into the “Americas” (AMER) segment and renamed our Asia segment “Asia Pacific” (APAC) and our Europe segment “Europe, Middle East and Africa” (EMEA) to better represent our long-range regional focus. As a result, we have conformed all prior period segment presentations to be consistent with our current reportable segments.

              On February 16, 2011, as previously announced, the Company’s Board of Directors approved a new share repurchase program that authorizes the Company to repurchase up to $200 million of common stock. As of April 2, 2011, the Company has repurchased 2.7 million shares for approximately $83.4 million, at an average price of $30.57 per share. These shares were recorded as treasury stock. Related to the share repurchase program, on April 21, 2011 the Company entered into a Note Purchase Agreement with certain institutional investors related to $175 million in principal amount of 5.20% Senior Notes, due on June 15, 2018 (the “Notes”). The Company issued $100 million in principal amount of the Notes on April 21, 2011, and it will issue the remaining $75 million on June 15, 2011.

              Three months ended April 2, 2011. Net sales for the three months ended April 2, 2011, of $568.1 million increased by $77.1 million, or 15.7 percent, as compared to the three months ended April 3, 2010. The net sales increase in the current year period was driven primarily by higher end-market demand from numerous existing customers in each of our market sectors except wireless infrastructure, as well as the addition of new customers in the medical and industrial/commercial sectors. Net sales to Juniper Networks, Inc. (“Juniper”), our largest customer, increased as a result of improved end-market demand for the mix of Juniper products we produce.

              Gross margins were 9.8 percent for the three months ended April 2, 2011, which compared unfavorably to 10.3 percent for the three months ended April 3, 2010. The current year period included higher fixed expenses, primarily in Asia Pacific, Americas and Corporate, related to higher headcount to support the revenue growth and annual merit increases. Changes in customer mix also contributed to the decrease in gross margins.

              Selling and administrative expenses for the three months ended April 2, 2011 were $29.1 million, an increase of $2.0 million, or 7.3 percent, over the three months ended April 3, 2010. The current year period increase was primarily related to increased headcount to support the higher revenue levels achieved and personnel related expenses.

              Net income for the three months ended April 2, 2011 increased by $3.1 million, or 15.2 percent, to $23.9 million from the three months ended April 3, 2010 and diluted earnings per share increased to $0.59 in the current year period from $0.51 in the prior year period. Net income increased due to higher sales, partially offset by increased fixed as well as selling and administrative expenses primarily as a result of increased headcount to support the revenue growth. The effective tax rate in both the current year and prior year periods was 3 percent. We currently benefit from reduced taxes in the Asia Pacific segment due to tax holidays.

              Six months ended April 2, 2011. Net sales for the six months ended April 2, 2011, of $1,133.9 million increased by $212.5 million, or 23.1 percent, as compared to the six months ended April 3, 2010. The net sales increase in the current year period was driven primarily by higher end-market demand from numerous existing customers in each of our market sectors except wireless infrastructure, as well as the addition of new customers in the medical and industrial/commercial sectors. Net sales to Juniper, increased as a result of improved end-market demand for the mix of Juniper products we produce.

              Gross margins were 9.7 percent for the six months ended April 2, 2011, which compared unfavorably to 10.3 percent for the six months ended April 3, 2010. The prior year period benefited from approximately $3.2 million of proceeds from a litigation settlement. Excluding the prior year settlement, the gross margin percentage in the current year period would have increased slightly over the prior year as a result of increased net sales and the mix of customer revenue, partially offset by an increase in fixed expenses primarily in the Americas and Asia Pacific reportable segments, related to higher headcount to support revenue growth and annual merit increases.

              Selling and administrative expenses for the six months ended April 2, 2011 were $56.1 million, an increase of $4.7 million, or 9.2 percent, over the six months ended April 3, 2010. The current year period increase was primarily related to increased headcount to support the higher revenue levels achieved and increased stock based compensation expense, partially offset by funds from a dispute recovery and lower variable incentive compensation expense.

              Net income for the six months ended April 2, 2011 increased by $10.3 million, or 26.8 percent, to $48.9 million from the six months ended April 3, 2010 and diluted earnings per share increased to $1.19 in the current year period from $0.95 in the prior year period. Net income increased due to higher sales, partially offset by increased fixed as well as selling and administrative expenses primarily as a result of increased headcount to support the revenue growth. The effective tax rate in the current year period was 3 percent as compared to 2 percent in the prior year period. The increase in the effective tax rate for the current year period as compared to the prior year period was primarily due to a change in mix of forecasted earnings in the jurisdictions in which we operate. As demonstrated in recent quarters, the tax rate can vary during the year based on the mix of forecasted earnings by tax jurisdiction. We currently benefit from reduced taxes in the Asia Pacific segment due to tax holidays.

RESULTS OF OPERATIONS

              Net sales. Net sales for the indicated periods were as follows (dollars in millions):

		Three Months Ended								Variance								Six Months Ended								Variance
		April 2,				April 3,												April 2,				April 3,
		2011				2010				Increase /(Decrease)								2011				2010				Increase /(Decrease)
Net Sales		$	568.1			$	491.0			$	77.1				15.7	%		$	1,133.9			$	921.4			$	212.5				23.1	%

              For the three months ended April 2, 2011, our net sales increase of 15.7 percent was the result of higher net sales in all market sectors except wireless infrastructure. The overall sales increase is due to improved end-market demand from numerous existing customers, as well as the addition of new customers in the medical and industrial/commercial sectors. The wireless infrastructure sector decreased due to decreased demand from one customer and the continued disengagement of another customer in that sector. Net sales to Juniper increased as a result of improved end-market demand for the mix of Juniper products we produce.

              For the six months ended April 2, 2011, our net sales increase of 23.1 percent as compared to the prior year was the result of the same factors described above.

              Our percentages of net sales by market sector for the indicated periods were as follows:

		Three Months Ended								Six Months Ended
		April 2,				April 3,				April 2,				April 3,
Industry		2011				2010				2011				2010
Wireline/Networking			40	%			43	%			41	%			44	%
Wireless Infrastructure			6	%			14	%			8	%			13	%
Medical			23	%			19	%			22	%			19	%
Industrial/Commercial			22	%			17	%			21	%			16	%
Defense/Security/Aerospace			9	%			7	%			8	%			8	%

              The percentages of net sales to customers representing 10 percent or more of net sales and net sales to our ten largest customers for the indicated periods were as follows:

		Three Months Ended								Six Months Ended
		April 2,				April 3,				April 2,				April 3,
		2011				2010				2011				2010
Juniper			16	%			15	%			17	%			16	%
Top 10 customers			53	%			57	%			54	%			59	%

              Net 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 demand and other factors, including global economic conditions. Any material change in forecasts or 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 the economic and business conditions affecting that sector.

              In the current economic environment, we are seeing increased merger and acquisition activity that has already impacted, and may continue to impact, our customers. Specifically, two of our customers were acquired in the first quarter of fiscal 2010. Our production for these two customers is ramping down during the first half of fiscal 2011 and full disengagement of both customers is expected by the end of the fiscal year.

              Gross profit. Gross profit and gross margins for the indicated periods were as follows (dollars in millions):

		Three Months Ended								Variance								Six Months Ended								Variance
		April 2,				April 3,												April 2,				April 3,
		2011				2010				Increase /(Decrease)								2011				2010				Increase /(Decrease)
Gross Profit		$	55.5			$	50.5			$	5.0				9.9	%		$	110.4			$	95.0			$	15.4				16.2	%
Gross Margin			9.8	%			10.3	%											9.7	%			10.3	%

              For the three months ended April 2, 2011, gross profit was impacted by the following factors:

•

increased capacity utilization from higher revenue levels in the current year period, which resulted in higher gross margin

	•		partially offset by increased fixed expenses in the current year period, primarily in the Asia Pacific, Americas and Corporate reportable segments, due to annual merit increases and higher headcount expense of approximately $6.2 million to support the revenue growth, and
	•		a change in customer mix as we ramped down two significant customers and ramped up other new programs that are inherently less profitable in their early stages.

              For the six months ended April 2, 2011, gross profit was impacted by the following factors:

	•		increased capacity utilization from higher revenue levels in the current year period, which resulted in higher gross margin
	•		partially offset by increased fixed expenses in the current year period, primarily in the Americas and Asia Pacific reportable segments, due to annual merit increases and higher headcount expense of approximately $14.3 million to support the revenue growth
	•		a $3.2 million benefit in the fiscal first quarter of 2010 from a litigation settlement, and
	•		a change in customer mix as we ramped down two significant customers and ramped up other new programs that are inherently less profitable in their early stages.

              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 resulting from the transition of new programs, product life cycles, sales volumes, price reductions, overall capacity utilization, labor costs and efficiencies, the management of inventories, component pricing and shortages, fluctuations and timing of customer orders, changing demand for our customers’ products and competition within the electronics industry. During fiscal 2010, we were in a constrained supply environment, which caused periods of parts shortages and delays for some components based on lack of capacity at some of our suppliers to meet increased demand from the gradually improving economic outlook. The March 2011 earthquake and tsunami in Japan has disrupted the global supply chain for certain components manufactured in Japan that are incorporated in the products we manufacture. While we have yet to experience a material adverse effect resulting from this event, the magnitude and duration of the impact on us relating to this event is not yet known. We continue to monitor the effect of the events in Japan on our supply chain. Shortages and delays could negatively impact net sales, inventory levels, component costs and margin. 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 maintaining gross margins, there can be no assurance that gross margins will not decrease in future periods.

              Design work performed by the Company is not the proprietary property of Plexus and substantially all costs incurred with this work are considered reimbursable by our customers. We do not track research and development costs that are not reimbursed by our customers as we consider these amounts immaterial.

              Selling and administrative expenses. Selling and administrative expenses (“S&A”) for the indicated periods were as follows (dollars in millions):

		Three Months Ended								Variance								Six Months Ended								Variance
		April 2,				April 3,												April 2,				April 3,
		2011				2010				Increase/(Decrease)								2011				2010				Increase/(Decrease)
S&A		$	29.1			$	27.1			$	2.0				7.3	%		$	56.1			$	51.4			$	4.7				9.2	%
Percent of net sales			5.1	%			5.5	%											5.0	%			5.6	%

              For the three months ended April 2, 2011, the dollar increase in S&A was due primarily to an increase in headcount and personnel related expenses of approximately $2.0 million to support the higher revenue levels achieved. S&A as a percentage of net sales decreased during the fiscal second quarter of 2011 as a result of net revenue expanding more quickly than these costs increased.

              For the six months ended April 2, 2011, the dollar increase in S&A was due primarily to higher headcount expense of approximately $4.8 million to support the higher revenue levels achieved and higher stock based compensation expense of approximately $0.7 million, partially offset by a dispute recovery of approximately $0.8 million and lower variable incentive compensation expense of approximately $0.7 million. S&A as a percentage of net sales decreased during the first half of fiscal 2011 as a result of net revenue expanding more quickly than these costs increased.

              Income taxes. Income taxes for the indicated periods were as follows (dollars in millions):
