PLEXUS CORP. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

FOR THE THREE AND NINE MONTHS ENDED JUNE 30, 2012 AND JULY 2, 2011

Unaudited

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 (together “Plexus,” the “Company,” or “we”) without audit and pursuant to the rules and regulations of the United States (“U.S.”) 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 June 30, 2012 and October 1, 2011, and the results of operations for the three and nine months endedJune 30, 2012 and July 2, 2011, and the cash flows for the same nine month periods.

Certain information and footnote disclosures, normally included in financial statements prepared in accordance with generally accepted accounting principles, have been condensed or omitted pursuant to the SEC’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 2011 Annual Report on Form 10-K.

The Company’s reportable segments consist of the “Americas” (“AMER”) segment, “Asia-Pacific” (“APAC”) segment and “Europe, Middle East, and Africa” (“EMEA”) segment. Refer to Note 10, "Business Segment and Major Customer Information," for further details on reportable segments.

Revision of prior period financial statements

During the second quarter of fiscal 2012, the Company revised its previously issued financial statements as a result of a correction to the classification of upfront payments made for land use rights in certain foreign countries. Refer to Note 16, "Revision of Prior Period Financial Statements," for further discussion of these revisions.

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 and are classified as Level 1 in the fair level hierarchy described below.

Fair Value of Financial Instruments

The Company holds financial instruments consisting of cash and cash equivalents, accounts receivable, accounts payable, debt, derivatives, and capital lease obligations. The carrying values of cash and cash equivalents, accounts receivable, accounts payable, derivatives, 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 long-term debt was $259.0 million and $274.3 million as of June 30, 2012 and October 1, 2011, respectively. The carrying value of the Company’s long-term debt was $261.3 million and $272.5 million as of June 30, 2012 and October 1, 2011, respectively. The Company uses quoted market prices when available or discounted cash flows to calculate the fair value of its debt. If measured at fair value in the financial statements, long-term debt (including the current portion) would be classified as Level 2 in the fair value hierarchy described below. Refer to Note 6, "Derivatives and Fair Value Measurements," for further details on derivatives.

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

6

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—BUSINESS COMBINATION

In the second quarter of fiscal 2012, Plexus and Kontron AG (“Kontron”) entered into a strategic manufacturing arrangement, and completed the related asset purchase transaction described below. Under this arrangement, Kontron transitioned all manufacturing of its Kontron Design Manufacturing Services (M) Sdn. Bhd. subsidiary (“KDMS”) located in Penang, Malaysia to Plexus facilities in Penang. Plexus acquired the inventory and equipment of KDMS for an initial purchase price of $35.2 million, which was paid with cash on-hand, and hired substantially all of KDMS's employees. No real estate was included in this transaction. This transaction has been accounted for as a business combination. The purchase price was allocated primarily to inventory and equipment. An identifiable intangible asset related to a customer relationship was recorded within other non-current assets in the Company's accompanying Condensed Consolidated Balance Sheets as a result of the arrangement and will be amortized on a straight-line basis over a two year period. Under this arrangement, Kontron also committed to approximately $100 million of incremental revenue annually for two years. In the three months ended June 30, 2012, the Company recorded a $1.1 million purchase price adjustment as a result of a post closing adjustment, for which the cash was received in the third quarter of fiscal 2012. The purchase price allocation may be further adjusted to reflect final valuation of the assets acquired. Assuming this transaction had been made at the beginning of any period presented, the consolidated pro forma results would not be materially different from reported results.

NOTE 3—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):

	June 30, 2012		October 1, 2011
Raw materials	$	355,014	$	337,136
Work-in-process	51,838		46,330
Finished goods	80,897		72,370
	$	487,749	$	455,836

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 June 30, 2012 and October 1, 2011 was $33.3 million and $29.8 million, respectively.

NOTE 4—PROPERTY, PLANT AND EQUIPMENT

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

	June 30, 2012		October 1, 2011
Land, buildings and improvements	$	169,793	$	143,254
Machinery and equipment	298,337		278,807
Computer hardware and software	87,511		83,373
Construction in progress	20,633		40,553

Less: accumulated depreciation	323,273		298,171
	$	253,001	$	247,816

Note certain fiscal 2011 property, plant and equipment amounts have been revised as described in Note 16, "Revision of Prior Period Financial Statements."

NOTE 5—DEBT

On May 15, 2012, the Company entered into a five-year, $250 million senior unsecured credit facility that terminates on May 15, 2017 (the “New Credit Facility”). The New Credit Facility includes a $160 million revolving credit facility and a $90 million term loan. The revolving credit facility may be increased by $100 million (the "increase option") to $260 million generally by mutual agreement of the Company, the lenders, the letter of credit issuers and the administrative agent named in the related credit agreement (the "Credit Agreement"), subject to certain customary conditions. The New Credit Facility was used to refinance the Company's then-existing $100 million senior unsecured revolving credit facility (no amounts were outstanding as of May 15, 2012) and its $150 million senior unsecured term loan (balance of $90.0 million as of May 15, 2012), both of which were scheduled to mature on April 4, 2013 (the “Prior Credit Facility”), and for general corporate purposes.

The financial covenants (as defined under the New Credit Facility) require that the Company maintain, as of each fiscal quarter end, a maximum total leverage ratio and a minimum interest coverage ratio. As of June 30, 2012, the Company was in compliance with all covenants of the New Credit Facility. Borrowings under the New Credit Facility, at the Company's option, bear interest at a defined base rate or the LIBOR rate plus, in each case, an applicable margin based upon the Company's leverage ratio as defined in the Credit Agreement. 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% or base rate plus 0%. The Company is also required to pay an annual commitment fee on the unused revolver credit commitment based on the Company's leverage ratio; the fee was 0.20% as of June 30, 2012.

In connection with the New Credit Facility, the Company incurred approximately $0.9 million in new debt issuance costs, which are being amortized over the five-year term of the New Credit Facility. In addition, at the time of the refinancing the Company expensed approximately $0.2 million related to the transactions.

The Company repaid $3.75 million of term loans outstanding on its New Credit Facility in the third quarter of fiscal 2012. During each of the first two quarters of fiscal 2012, the Company repaid $3.75 million of term loans outstanding on its Prior Credit Facility. As of June 30, 2012, the Company had term loan borrowings of $86.3 million outstanding and no revolving borrowings under the New Credit Facility.

During each of the first three quarters of fiscal 2011, the Company repaid $3.75 million each quarter of term loans outstanding under its Prior Credit Facility. As of July 2, 2011, the Company had term loan borrowings of $101.3 million outstanding and no revolving borrowings under the Prior Credit Facility.

During the third quarter of fiscal 2011, the Company entered into a Note Purchase Agreement with certain institutional investors and issued $175 million in principal of 5.20% Senior Notes, due on June 15, 2018 (the “Notes”). The Company had $175 million principal of Notes outstanding as of both June 30, 2012 and July 2, 2011.

NOTE 6—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 foreign currency obligations. 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.

The Company’s Mexican operations were parties to forward exchange contracts all of which were settled as of June 30, 2012. The total fair value of these forward contracts was a $1.0 millionliability as of October 1, 2011.

During the second quarter of fiscal 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 the Company’s fourth facility in Malaysia; these contracts were settled as of the end of the first quarter of fiscal 2012. The total fair value of these forward contracts was a $0.1 millionliability as of October 1, 2011.

The Company’s Malaysian operations have also entered into forward exchange contracts on a rolling basis with a total notional value of $54.1 million as of June 30, 2012. These forward contracts will fix the exchange rates on foreign currency cash used to pay a portion of local currency expenses. The total fair value of these forward contracts was a $1.4 millionliability as of June 30, 2012 and a $1.5 millionliability as of October 1, 2011.

8

During fiscal 2011, the Company entered into 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. During the third quarter of fiscal 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 is being amortized over the seven year term of the related debt.

The Company entered into three interest rate swap contracts related to the $150 million in term loans under its Prior Credit Facility that had an initial total notional value of $150 million and mature on April 4, 2013. These interest rate swap contracts continued into the New Credit Facility and pay the Company variable interest at the three month LIBOR rate, and the Company pays 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 originally entered into to convert $150 million of the variable rate term loan under the Prior 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 a $2.5 millionliability as of June 30, 2012 and a $5.2 millionliability as of October 1, 2011. As of June 30, 2012, the total remaining combined notional amount of the Company’s three interest rate swaps was $86.3 million.

Interest rate swaps	$	—	$	(2,515	)	$	—	$	(2,515	)
Foreign currency forward contracts	$	—	$	(1,407	)	$	—	$	(1,407	)

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.

NOTE 7—EARNINGS PER SHARE

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

	Three Months Ended				Nine Months Ended
	June 30, 2012		July 2, 2011		June 30, 2012		July 2, 2011
Basic and Diluted Earnings Per Share:
Net income	$	23,533	$	22,040	$	61,361	$	70,933
Basic weighted average common shares outstanding	34,982		37,021		34,819		39,135
Dilutive effect of share-based awards outstanding	661		839		682		788
Diluted weighted average shares outstanding	35,643		37,860		35,501		39,923
Earnings per share:
Basic	$	0.67	$	0.60	$	1.76	$	1.81
Diluted	$	0.66	$	0.58	$	1.73	$	1.78

For the three and nine months endedJune 30, 2012, stock options and stock-settled stock appreciation rights ("SARS") for approximately 1.4 million and 1.3 million shares, respectively, 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 Company's common shares and, therefore, their effect would be anti-dilutive. For both the three and nine months endedJune 30, 2012, restricted stock units (“RSUs”) of approximately 0.1 million units were outstanding but were not included in the computation of diluted earnings per share because their effect would have been anti-dilutive.

10

For the three and nine months endedJuly 2, 2011, stock options and stock-settled SARs for approximately 1.1 million and 1.2 million shares, respectively, 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 Company's common shares and, therefore, their effect would be anti-dilutive. For three and nine months endedJuly 2, 2011, none of the RSUs outstanding had an anti-dilutive effect.

NOTE 8—STOCK-BASED COMPENSATION

The Company recognized $3.2 million and $9.6 million of compensation expense associated with stock-based awards for the three and nine months endedJune 30, 2012, respectively, and $2.7 million and $8.2 million for the three and nine months endedJuly 2, 2011, 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 RSUs and unrestricted stock awards. The Company recognizes stock-based compensation expense over the stock-based awards’ vesting period.

NOTE 9—INCOME TAXES

Income tax expense for the three and nine months endedJune 30, 2012 was $1.9 million and $6.1 million, respectively. The effective tax rates for the three and nine months endedJune 30, 2012 were 8 and 9 percent, respectively. 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 APAC segment due to tax holidays in Penang, Malaysia and Xiamen, China.

Income tax expense for the three and nine months endedJuly 2, 2011 was $0.7 million and $2.2 million, respectively. The effective tax rates for both the three and nine months endedJuly 2, 2011 were 3 percent.

As of June 30, 2012, there was no material change in the amounts recorded for uncertain tax positions as compared to the fiscal 2011 year end. 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 nine months endedJune 30, 2012 and July 2, 2011 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. The Company is currently under examination by taxing authorities in the U.S. for fiscal years 2008 through 2010 and is not undergoing any tax examinations in any of its major foreign jurisdictions. The U.S. examination may be resolved within the next twelve months, but at this time it is not possible to estimate the amount of the effects of any changes to the Company's previously recorded uncertain tax positions.

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. As of June 30, 2012, there was no material change in the valuation allowance as compared to the fiscal 2011 year end. Despite losses in fiscal years 2009-2011 in the U.S. tax jurisdiction, the Company’s U.S. operations generated income for the three and nine months endedJune 30, 2012. Based on the weight of all the evidence, both positive and negative, it is more likely than not that the Company will be able to utilize its U.S. net deferred tax assets and no valuation allowance is warranted. However, if the Company’s U.S. operations cannot sustain forecasted profitability, there may be a need to provide a valuation allowance on the Company’s net U.S. deferred tax assets which approximate $21.4 million as of June 30, 2012.

NOTE 10—BUSINESS SEGMENT 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.

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.

11

	Three Months Ended				Nine Months Ended
	June 30, 2012		July 2, 2011		June 30, 2012		July 2, 2011
Juniper Networks, Inc. (“Juniper”)	16	%	17	%	17	%	17	%

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.

12

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 2011 and for the nine months endedJune 30, 2012 (in thousands):

Limited warranty liability, as of October 2, 2010	$	4,055
Accruals for warranties issued during the period	1,714
Settlements (in cash or in kind) during the period	(316		)
Limited warranty liability, as of October 1, 2011	5,453
Accruals for warranties issued during the period	349
Settlements (in cash or in kind) during the period	(912		)
Limited warranty liability, as of June 30, 2012	$	4,890

NOTE 12—LITIGATION

In fiscal 2010, the Company incurred approximately $1.1 million of costs relating to non-conforming inventory received from a supplier. The Company reached a settlement with the supplier during the first quarter of fiscal 2011 for $0.9 million, which was received and recorded in selling and administrative expenses in fiscal 2011.

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. During September 2010, the Company reported errors relating to import trade activity from July 2004 to the date of Plexus' report. CBP has indicated that on-site fieldwork for the audit was completed as of June 2011, and 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. We recorded an accrual in other current accrued liabilities in the first quarter of fiscal 2010 when the amount became estimable and probable, which was not material to the financial statements. 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—SHAREHOLDERS’ EQUITY

No share repurchases were completed by the Company during the nine months endedJune 30, 2012.

For the nine months endedJuly 2, 2011, the Company repurchased 5.3 million shares for approximately $170.4 million, at a weighted average price of $32.24 per share.

NOTE 15—NEW ACCOUNTING PRONOUNCEMENTS

In December 2011, the Financial Accounting Standards Board (“FASB”) issued an amendment to disclosures about offsetting assets and liabilities. The amended standard requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. An entity is required to apply the amendments for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. An entity should provide the disclosures required by those amendments retrospectively for all comparative periods presented. The adoption of this guidance is not anticipated to have a material impact on the Company’s consolidated results of operations, financial position and cash flows.

In June 2011, the FASB issued an amendment to comprehensive income guidance, which eliminates the option to present other comprehensive income (“OCI”) and its components in the statement of shareholders’ equity. The Company can elect to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. Under the two-statement approach, the first statement would include the components of net income, and the second statement would include the components of OCI. This guidance is effective for financial statements issued for fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption of this guidance is not anticipated to have a material impact on the Company’s consolidated results of operations, financial position and cash flows.

NOTE 16—REVISION OF PRIOR PERIOD FINANCIAL STATEMENTS

In the second quarter of fiscal 2012, the Company identified prior period errors in its consolidated financial statements related to the Condensed Consolidated Balance Sheets and Condensed Consolidated Statements of Cash Flows classification of upfront payments made for land use rights. Specifically, the Company had historically accounted for the upfront payments for the land use rights as capital leases within property, plant and equipment and as investing activities in the Condensed Consolidated Statements of Cash Flows. The Company has determined that the upfront payments made for land use rights should have been reflected as an operating lease within other long-term assets on the Condensed Consolidated Balance Sheets and as operating activities within the Condensed Consolidated Statements of Cash Flows. There was no impact of the error corrections on the Consolidated Statements of Operations. In evaluating whether the Company’s previously issued consolidated financial statements were materially misstated, the Company considered the guidance in Accounting Standard Codification (ASC) Topic 250, Accounting Changes and Error Corrections, ASC Topic 250-10-S99-1, Assessing Materiality, and ASC Topic 250-10-S99-2, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements. The Company concluded these errors were not material individually or in the aggregate to any of the prior reporting periods. The impact of these corrections to the applicable prior periods are reflected in the financial information and notes herein and will be reflected in future filings containing affected financial information. The impact of these revisions on the financial statements included in the Company’s 2011 Annual Report on Form 10-K and previously filed 2012 and 2011 Forms 10-Q is described below. In addition, footnotes impacted by the above error will also be revised in future filings.

Revisions to the Condensed Consolidated Balance Sheets reflect a decrease in property, plant and equipment and an increase to other long-term assets in the amounts of $17.6 million, $17.7 million, and $14.8 million as of December 31, 2011, October 1, 2011, and October 2, 2010, respectively.

During the fourth quarter of fiscal 2010 and the first quarter of fiscal 2011, the Company made upfront payments for land use rights in the amount of $9.6 million and $3.2 million, respectively. These payments were classified as capital expenditures within investing activities in the Consolidated Statements of Cash Flows for fiscal 2010 and 2011 and each quarterly period in fiscal 2011, respectively. The classification of these payments has been corrected to properly reflect these amounts as operating cash outflows rather than investing cash outflows in the financial information included herein and will be corrected in the relevant periods in future filings. There will also be inconsequential revisions to depreciation and change in prepaid expense and other within the operating activities section of the Consolidated Statements of Cash Flows in future filings. The revised totals for operating cash flows and investing cash flows are $158.5 million and $(68.7) million for fiscal 2011, $(7.6) million and $(64.8) million for fiscal 2010, and $(24.3) million and $(10.0) million, $48.4 million and $(24.2) million, and $64.0 million and $(42.1) million during the three, six, and nine months ended for fiscal 2011, respectively.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

“SAFE HARBOR” CAUTIONARY STATEMENT:

The statements contained in this release which are guidance or which are not historical facts (such as statements in the future tense and statements including believe, expect, intend, plan, anticipate, goal, target and similar terms and concepts), including all discussions of periods which are not yet completed, are forward-looking statements that involve risks and uncertainties. These risks and uncertainties include, but are not limited to: the risk of customer delays, changes, cancellations or forecast inaccuracies in both ongoing and new programs; the poor visibility of future orders, particularly in view of current economic conditions; the economic performance of the industries, sectors and customers we serve; the effects of the volume of revenue from certain sectors or programs on our margins in particular periods; the risk that our recent agreement with Kontron does not result in the revenues or margins anticipated by us; our ability to secure new customers, maintain our current customer base and deliver product on a timely basis; the risk that our revenue and/or profits associated with customers who are acquired by third parties will be negatively affected; the particular risks relative to new or recent customers or programs, which risks include customer and other delays, start-up costs, potential inability to execute, the establishment of appropriate terms of agreements, and the lack of a track record of order volume and timing; the risks of concentration of work for certain customers; our ability to manage successfully a complex business model characterized by high customer and product mix, low volumes and demanding quality, regulatory, and other requirements; the risk that new program wins and/or customer demand may not result in the expected revenue or profitability; the fact that customer orders may not lead to long-term relationships; the effects of shortages and delays in obtaining components as a result of economic cycles or natural disasters; raw materials and component cost fluctuations, particularly due to sudden increases in customer demand; the risks associated with excess and obsolete inventory, including the risk that inventory purchased on behalf of our customers may not be consumed or otherwise paid for by the customer, resulting in an inventory write-off; the weakness of the global economy and the continuing instability of the global financial markets and banking system, including the potential inability of our customers or suppliers to access credit facilities; the effect of changes in the pricing and margins of products; the effect of start-up costs of new programs and facilities, such as our announced plans to expand in Romania and the United States, and recent, planned and potential future expansions; the risk of unanticipated costs, unpaid duties and penalties related to an ongoing audit of our import compliance by U.S. Customs and Border Protection; increasing regulatory and compliance requirements; possible unexpected costs and operating disruption in transitioning programs; the potential effect of fluctuations in the value of the currencies in which we transact business; the potential effect of world or local events or other events outside our control (such as drug cartel-related violence in Mexico, changes in oil prices and terrorism); the impact of increased competition; and other risks detailed in the Company's Securities and Exchange Commission filings (particularly in Part I, Item 1A of our annual report on Form 10-K for the fiscal year ended October 1, 2011).

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 1, 2011 and our “Safe Harbor” Cautionary Statement included above.

Plexus Corp. and its subsidiaries (together “Plexus,” the “Company,” “we” or “our”) deliver optimized Product Realization solutions in the Electronic Manufacturing Services (“EMS”) industry through a unique Product Realization Value Stream services model. This customer focused services model seamlessly integrates innovative product conceptualization, design, commercialization, manufacturing, fulfillment and sustaining services to deliver comprehensive end-to-end solutions for customers in the Americas (“AMER”), Europe, Middle East, and Africa (“EMEA”) and Asia-Pacific (“APAC”) regions. Customer service is provided to over 130 branded product companies in the Networking/Communications, Medical, Industrial/Commercial and Defense/Security/Aerospace market sectors. Our customers’ products typically require exceptional production and supply-chain flexibility, necessitating an optimized demand-driven 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.

We provide most of our contract manufacturing services on a turnkey basis, procuring some or all of the materials required for product assembly. We also provide some services on a consignment basis. In these cases, the customers supply 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

15

services. Other than certain test equipment and software used for internal operations, we do not design or manufacture our own proprietary products.

As discussed in Results of Operations below, we are substantially dependent on our largest customers. Our revenue from these customers may vary from time to time depending on the size and timing of customer program commencements, terminations, delays, modifications and transitions. We generally do not obtain firm, long-term purchase commitments from our customers. Because customers’ forecasts can and do change as a result of changes in their end-market demand and other factors, including global economic conditions, they may, at any time, materially change the type and volume of manufacturing services required. 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 response to the evolving markets and to better reflect our customers’ end markets, we decided to combine our Wireline/Networking and Wireless Infrastructure market sectors and rename them as our Networking/Communications market sector, beginning in the first quarter of fiscal 2012. As a result, we have conformed all prior period market sector presentations to be consistent with our current market sectors.

RESULTS OF OPERATIONS

Consolidated Performance Summary

The following table presents selected consolidated financial data (dollars in millions, except per share data):

	Three Months Ended						Nine Months Ended
	June 30, 2012			July 2, 2011			June 30, 2012			July 2, 2011
Net sales	$	608.8		$	559.2		$	1,711.9		$	1,693.1

Earnings per share (diluted)	$	0.66		$	0.58		$	1.73		$	1.78
Return on invested capital							15.0		%	16.2		%

Net sales. For the three months endedJune 30, 2012, our net sales increase of 8.9 percent compared to the three months endedJuly 2, 2011 was the result of the continued ramp of a significant industrial/commercial sector customer, incremental revenue from the previously announced Kontron strategic arrangement (the “Kontron arrangement”), and program ramps from several other existing customers. These increases in net sales were partially offset by decreased sales in the networking/communications sector due to lower end-market demand, including the prior year disengagement of a customer in this sector as a result of its acquisition.

For the nine months endedJune 30, 2012, our net sales increase of 1.1 percent compared to the nine months endedJuly 2, 2011 was the result of the same factors noted above for the three-month period along with the addition of a new customer in the defense/security/aerospace sector, partially offset by an additional prior year customer disengagement from the networking/communications sector as a result of its acquisition.

16

Our net sales by market sector for the indicated periods were as follows (in millions):

	Three Months Ended				Nine Months Ended
Market Sector	June 30, 2012		July 2, 2011		June 30, 2012		July 2, 2011
Networking/Communications	$	236.8	$	258.3	$	676.3	$	816.3
Industrial/Commercial	187.1		130.0		511.4		371.2
Medical	127.3		114.5		356.2		357.9
Defense/Security/Aerospace	57.6		56.4		168.0		147.7
	$	608.8	$	559.2	$	1,711.9	$	1,693.1

Networking/Communications. Net sales for the networking/communications sector decreased $21.5 million for the three months endedJune 30, 2012 compared to the three months endedJuly 2, 2011. The decline in the sector was a result of the impact from the prior year disengagement of a significant customer as a result of its acquisition and overall unfavorable end-market trends reflecting global economic uncertainty.

Net sales for the networking/communications sector decreased $140.0 million for the nine months endedJune 30, 2012 compared to the nine months endedJuly 2, 2011. The decline in the sector was a result of the same factors noted above for the three-month period along with the impact of one other prior year customer disengagement as a result of its acquisition.

Industrial/Commercial. Net sales for the industrial/commercial sector increased $57.1 million for the three months endedJune 30, 2012 compared to the three months endedJuly 2, 2011. The increase was primarily attributable to the continued ramp of a significant customer, incremental revenue related to the Kontron arrangement, and the addition of a new customer in this sector.

Net sales for the industrial/commercial sector increased $140.2 million for the nine months endedJune 30, 2012 compared to the nine months endedJuly 2, 2011. The increase in the sector was a result of the same factors noted above for the three-month period.

Medical. Net sales for the medical sector increased $12.8 million for the three months endedJune 30, 2012 compared to the three months endedJuly 2, 2011. The increase was primarily due to market share gain.

Net sales for the medical sector decreased $1.7 million for the nine months endedJune 30, 2012 compared to the nine months endedJuly 2, 2011. The decrease was due to lower overall end-market demand in the market sector for the first half of the fiscal year partially offset by performance in the current three-month period noted above.

Defense/Security/Aerospace. Net sales for the defense/security/aerospace sector increased $1.2 million for the three months endedJune 30, 2012 compared to the three months endedJuly 2, 2011. The slight increase was primarily due to relatively stable end-market demand overall.

Net sales for the defense/security/aerospace sector increased $20.3 million for the nine months endedJune 30, 2012 compared to the nine months endedJuly 2, 2011. The increase in the sector was primarily due to increased demand from an existing customer as a result of new program wins and a program ramp for a new customer.

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

	Three Months Ended		Nine Months Ended
	June 30, 2012	July 2, 2011	June 30, 2012	July 2, 2011
Juniper	16%	17%	17%	17%
Top 10 customers	60%	53%	62%	53%

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

The increase in the percentage of net sales from our top ten customers is primarily driven by the ramp of an industrial/commercial sector customer. Although we expect the majority of our top 10 customers to continue to grow in fiscal 2012, we also anticipate that the percentage of our overall sales to these customers will be slightly lower in full-year fiscal 2012, assuming our overall net sales increase. Because the majority of our net sales come from a relatively small number of

17

customers and a limited number of market sectors, if we lose any of these customers or if there are issues in those market sectors, our net sales and operating results could decline significantly.

Gross profit. For the three months endedJune 30, 2012, gross profit increased $3.3 million compared to the three months endedJuly 2, 2011 primarily due to the net sales increase. The increase was partially offset by increased fixed expenses related to higher headcount to support the revenue growth, increased transition costs for the Kontron arrangement, $0.9 million of higher variable compensation expense, and an unfavorable change in customer mix. Customer mix negatively impacted gross profit due to a higher portion of sales from new programs, which tend to be inherently less profitable than mature programs during early production stages. These factors led to the reduction in gross margin from 9.7 percent for the three months endedJuly 2, 2011 to 9.4 percent for the three months endedJune 30, 2012.

For the nine months endedJune 30, 2012, gross profit decreased $0.8 million compared to the nine months endedJuly 2, 2011 primarily due to increased fixed expenses related to higher headcount to support the revenue growth and transition costs for the Kontron arrangement. These expense increases were partially offset by a favorable outcome regarding inventory disposition related to a prior year customer disengagement, which had a $1.5 million positive effect. As a result of these factors, there was a slight decline in gross margin for the nine months endedJune 30, 2012 compared to the nine months endedJuly 2, 2011.

Operating income. For the three months endedJune 30, 2012, operating income increased $2.4 million compared to the three months endedJuly 2, 2011. The operating income increase reflected the $3.3 million increase in gross profit described above, partially offset by a $0.9 million increase in selling and administrative expenses (“S&A”). The dollar increase in S&A is primarily due to a $0.5 million increase in variable compensation expense, a $0.4 million increase in stock option expense, $0.4 million of amortization expense in the current period, and an increase of personnel expenses. These increases were partially offset by approximately $1.2 million of recoveries of receivables previously at risk. As a result of the factors discussed above, for the three months endedJune 30, 2012 compared to the three months endedJuly 2, 2011, operating margin was 4.5 percent for both periods.

For the nine months endedJune 30, 2012, operating income decreased $2.3 million compared to the nine months endedJuly 2, 2011. The operating income decrease reflected the $0.8 million decline in gross profit described above, and a $1.5 millionincrease in S&A. The dollar increase in S&A as compared to the prior year was due primarily to an increase in personnel expenses, an increase in stock-based compensation expense of $1.2 million, the effect of a favorable non-recurring litigation settlement during the first quarter of fiscal 2011 of $0.9 million (see Note 12 in Notes to Condensed Consolidated Financial Statements), and an increase of $0.8 million of amortization expense. These increases were partially offset by approximately $2.0 million of recoveries of receivables previously at risk and $0.9 million in lower variable compensation expense. As a result of the factors discussed above, for the nine months endedJune 30, 2012 compared to the nine months endedJuly 2, 2011, operating margin declined to 4.5 percent from 4.7 percent.

Other income (expense). Other income (expense) decreased to $1.8 million of expense for the three months endedJune 30, 2012 from $2.2 million of expense for the three months endedJuly 2, 2011. The decrease in expense was primarily due to a $0.8 million gain on the sale of previously owned assets, partially offset by increased interest expense related to the $175 million of borrowings under the Note Purchase Agreement that the Company entered into during the third quarter of fiscal 2011.

Other income (expense) increased to $9.3 million of expense for the nine months endedJune 30, 2012 from $6.0 million of expense for the nine months endedJuly 2, 2011. The increase in expense was primarily due to increased interest expense related to the $175 million of borrowings under the Note Purchase Agreement and a $0.4 million decrease in foreign currency exchange gains, partially offset by a $0.8 million gain on the sale of previously owned assets and a $0.4 million increase in interest income in the current year period.

Income taxes. Effective annual income tax rates for the indicated periods were as follows:

	Three Months Ended		Nine Months Ended
	June 30, 2012	July 2, 2011	June 30, 2012	July 2, 2011
Effective annual tax rate	8%	3%	9%	3%

Income tax expense increased to $1.9 million and $6.1 million for the three and nine months endedJune 30, 2012, respectively, as compared to $0.7 million and $2.2 million for the three and nine months endedJuly 2, 2011, respectively, as a result of the increase in our effective tax rate. These rates primarily vary from the U.S. statutory rate of 35 percent as a result of the amount of earnings from different U.S. and foreign jurisdictions, and tax holidays granted to our subsidiaries in China and Malaysia, where we derive a significant portion of our earnings. The effective tax rate for both the three and nine months endedJune 30,

18

2012 is higher than the effective rate for the three and nine months endedJuly 2, 2011 primarily as a result of increased profitability in the U.S. tax jurisdiction. Our effective tax rate could fluctuate in the future depending on the geographic distribution of our worldwide earnings.

The estimated annual effective tax rate for all of fiscal 2012 is expected to be 9 percent, a slight decrease from the prior quarter estimate due to the geographic shift in income described above.

Net income. Primarily as a result of higher net sales, and partially offset by lower gross margins and increased income tax expense, net income for the three months endedJune 30, 2012 increased by $1.5 million, or 6.8 percent, to $23.5 million from the three months endedJuly 2, 2011.

Primarily as a result of slightly lower gross margins and increases to income tax expense and other expense, net income for the nine months endedJune 30, 2012 decreased by $9.5 million, or 13.4 percent, to $61.4 million from the nine months endedJuly 2, 2011.

Diluted earnings per share. Diluted earnings per share increased to $0.66 for the three months endedJune 30, 2012, from $0.58 for the three months endedJuly 2, 2011. The increase in diluted earnings per share was primarily due to the increase in net income previously noted, along with the effect of a decrease in diluted weighted average shares outstanding as of June 30, 2012 as a result of our share repurchases completed in fiscal 2011.

Diluted earnings per share decreased to $1.73 for the nine months endedJune 30, 2012 from $1.78 for the nine months endedJuly 2, 2011. The decrease in diluted earnings per share was primarily due to the decrease in net income previously noted, partially offset by the effect of a decrease in diluted weighted average shares outstanding as of June 30, 2012 as a result of our share repurchases completed in fiscal 2011.

Return on Invested Capital (“ROIC”). We use a 5-10-5 financial model which is aligned with our business strategy, and includes a ROIC goal of 500 basis points over our weighted average cost of capital (“WACC”), a 10 percent gross margin target and a 5 percent operating margin target. Our primary focus is our ROIC goal, which is designed to create shareholder value and generate enough cash to self-fund our targeted organic revenue growth rate of 15 percent.

We review our internal calculation of WACC annually, and our estimated WACC is 12.5 percent for fiscal 2012. By exercising discipline to generate ROIC in excess of our WACC, our goal is to create value for our shareholders. ROIC was 15.0 percent and 16.2 percent for the nine months endedJune 30, 2012 and July 2, 2011, respectively. This decrease was due to slightly lower annualized operating income and an increase in the effective tax rate, partially offset by a decrease in average invested capital as defined below.

We define ROIC as tax-effected annualized operating income divided by average invested capital over a rolling four-quarter period for the third quarter. Invested capital is defined as equity plus debt, less cash and cash equivalents. Other companies may not define or calculate ROIC in the same way. ROIC is a non-GAAP financial measure which should be considered in addition to, not as a substitute for, measures of our financial performance prepared in accordance with United States generally accepted accounting principles (“GAAP”).

Non-GAAP financial measures, including ROIC, are used for internal management assessments because such measures provide additional insight into ongoing financial performance. In particular, we provide ROIC because we believe it offers insight into the metrics that are driving management decisions. We view ROIC as an important measure in evaluating the efficiency and effectiveness of our long-term capital requirements. We also use ROIC as a performance criteria in determining certain elements of compensation.

For a reconciliation of ROIC to our financial statements that were prepared using GAAP, see exhibit 99.1 to this quarterly report on Form 10-Q, which exhibit is incorporated herein by reference.

Americas (AMER): Net sales for the three months endedJune 30, 2012 increased $12.0 million, or 3.9 percent, as compared to the prior year period due to the continued ramp of a significant industrial/commercial market sector customer, increased demand from a customer in the networking/communications sector, and a new customer in the industrial/commercial sector. These increases were partially offset by soft demand from certain customers primarily in the networking/communications and defense/security/aerospace sectors. Operating income for the three months endedJune 30, 2012 increased $8.8 million, or 57.5 percent, as compared to the prior year period as a result of favorable changes in customer mix and approximately $1.1 million of recoveries of receivables previously at risk.

Net sales for the nine months endedJune 30, 2012 decreased $11.8 million, or 1.2 percent, as compared to the prior year period due to lower end-market demand from existing customers primarily in the networking/communications sector, including the prior year customer disengagement as a result of an acquisition in this sector. These decreases were partially offset by the continued ramp of a significant industrial/commercial market sector customer and a new customer in this sector as well. Operating income for the nine months endedJune 30, 2012 increased $20.7 million, or 39.3 percent, as compared to the prior year period due to a favorable customer mix, increase in engineering design and services profitability, approximately $1.6 million of recoveries of receivables previously at risk and the favorable outcome of an inventory disposition related to a prior year customer disengagement, which had a $1.5 million positive effect.

Asia Pacific (APAC): Net sales for the three months endedJune 30, 2012 increased $21.3 million, or 7.6 percent, as compared to the prior year period primarily due to incremental revenue from the Kontron arrangement and increased demand from several customers across all sectors. These increases were partially offset by decreased demand in the networking/communications sector, including the prior year disengagement of a customer as a result of acquisition. Operating income for the three months endedJune 30, 2012 decreased $2.8 million, or 9.2 percent, as compared to the prior year period due to an unfavorable customer mix, increased expenses related to higher headcount to support capacity investments as well as transition costs for the Kontron arrangement, partially offset by increased net sales.

Net sales for the nine months endedJune 30, 2012 decreased $20.9 million, or 2.6 percent, as compared to the prior year period primarily as a result of demand decrease primarily from the networking/communications sector along with decreases from two industrial/commercial sector customers. Operating income for the nine months endedJune 30, 2012 decreased $20.3 million, or 21.9 percent, as compared to the prior year period as a result of the net sales decline, increased expenses related to higher headcount to support capacity investments and transition costs for the Kontron arrangement.

Europe, Middle East, Africa (EMEA): Net sales for the three months endedJune 30, 2012 decreased $2.4 million, or 9.8 percent, as compared to the prior year period due primarily to decreased net sales to several industrial/commercial customers, partially offset by three new customers in the industrial/commercial, defense/aerospace/security and networking/

20

communications sectors. Operating loss for the three months endedJune 30, 2012 decreased $0.1 million, or 10.0 percent, as compared to the prior year period due to continued growth from our Romania facility, partially offset by decreased net sales from our United Kingdom ("UK") facility.

Net sales for the nine months endedJune 30, 2012 increased $0.5 million, or 0.7 percent, as compared to the prior year period due primarily to the addition of new customers in each of our market sectors, partially offset by decreased net sales to several industrial/commercial customers. Operating loss for the nine months endedJune 30, 2012 increased $0.3 million, or 25.0 percent, as compared to the prior year period due to a net sales decrease from our UK facility, partially offset by continued growth from our Romania facility.

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents were $277.9 million as of June 30, 2012 compared to $242.1 million as of October 1, 2011. The increase in the balance of our cash and cash equivalents was due primarily to cash generated from operations, partially offset by cash used for the Kontron arrangement, capital expenditures and payments on debt.

As of June 30, 2012, approximately two-thirds of our cash balance was held outside of the U.S. by our foreign subsidiaries. Certain foreign countries impose taxes and overall penalties on transfers of cash; however our intent is to permanently reinvest funds held in these countries. If this cash were remitted to the U.S., additional tax obligations may result that would reduce the amount of cash ultimately available to us in the U.S. Currently, we believe that cash held in the U.S., together with cash available under U.S. credit facilities and cash from foreign subsidiaries that could be remitted to the U.S. without tax consequences, will be sufficient to meet our U.S. liquidity needs for the next twelve months and for the foreseeable future.

Cash Flows. The table below shows a summary of cash flows for the periods presented (dollars in millions):

	Nine Months Ended
	June 30, 2012			July 2, 2011
Cash provided by operating activities	$	116.8		$	64.0
Cash used in investing activities	(74.5		)	(42.1		)
Cash used in financing activities	$	(6.4	)	$	(2.4	)

Operating Activities. Cash flows provided by operating activities were $116.8 million for the nine months endedJune 30, 2012, as compared to cash flows provided by operating activities of $64.0 million for the nine months endedJuly 2, 2011. Cash flows provided by operating activities increased primarily due to overall improved working capital changes, partially offset by lower net income.

The following table shows a summary of cash cycle days for the periods indicated (in days):

	Three Months Ended
	June 30, 2012	July 2, 2011
Days in accounts receivable	47	49
Days in inventory	81	88
Days in accounts payable	59	56
Days in cash deposits	6	6
Annualized cash cycle	63	75

We calculate days in accounts receivable as accounts receivable for the respective quarter divided by annualized sales for the respective quarter by day. We calculate days in inventory, accounts payable, and cash deposits as each balance sheet line item for the respective quarter divided by annualized cost of sales for the respective quarter by day.

Days in accounts receivable for the three months endedJune 30, 2012 decreased by two days compared to the three months endedJuly 2, 2011, primarily due to the favorable changes in payment terms for a significant customer and timing of collections.

Days in inventory for the three months endedJune 30, 2012 decreased by seven days compared to the three months endedJuly 2, 2011, due to our efforts to actively manage inventory levels down with the assistance of our customers, while continuing to meet our customers’ needs for flexibility and agility and maintain revenue growth.

21

Days in accounts payable for the three months endedJune 30, 2012 increased by three days compared to the three months endedJuly 2, 2011, primarily due to purchases to support higher expected revenue in the fourth quarter of fiscal 2012 compared to the prior year period and more favorable payment terms with a supplier.

Days in cash deposits for the three months endedJune 30, 2012 was consistent with the three months endedJuly 2, 2011 at six days.

We calculate annualized cash cycle as the sum of days in accounts receivable and days in inventory, less days in accounts payable and days in cash deposits. For the three months endedJune 30, 2012 annualized cash cycle days decreased by twelve days compared to the three months endedJuly 2, 2011 due to the factors noted above.

Free Cash Flow. Free cash flow (“FCF”), which we define as cash flow provided by (used in) operations less capital expenditures, increased for the nine months endedJune 30, 2012, to $71.7 million, as compared to FCF of $19.8 million for the nine months endedJuly 2, 2011. Better management of working capital partially offset by lower net income in the nine months endedJune 30, 2012 led to this improvement.

Non-GAAP financial measures, including FCF, are used for internal management assessments because such measures provide additional insight into ongoing financial performance. In particular, we provide FCF because we believe it offers insight into the metrics that are driving management decisions. We view FCF as an important financial metric as it demonstrates our ability to generate cash and allows us to pursue opportunities that enhance shareholder value. FCF is a non-GAAP financial measure which should be considered in addition to, not as a substitute for, measures of our financial performance prepared in accordance with U.S. GAAP.

For a reconciliation of FCF to our financial statements that were prepared using GAAP, see below (in millions):

	Nine Months Ended
	June 30, 2012			July 2, 2011
Cash provided by operating activities	$	116.8		$	64.0
Capital expenditures	(45.1		)	(44.2		)
Free cash flow	$	71.7		$	19.8

Investing Activities. Cash flows used in investing activities totaled $74.5 million for the nine months endedJune 30, 2012 as compared to cash flows used in investing activities of $42.1 million for the nine months endedJuly 2, 2011. Cash flows used in investing activities increased primarily due to the Kontron arrangement in the nine months endedJune 30, 2012.

We utilized available cash and operating cash flows as the sources for funding our operating requirements. We currently estimate capital expenditures for fiscal 2012 to be approximately $70-75 million of which $45.1 million of expenditures were made through the third quarter of fiscal 2012. A significant portion of the remaining fiscal 2012 capital expenditures is anticipated to be used for the construction of our previously announced manufacturing facilities in Neenah, Wisconsin and Oradea, Romania to replace leased buildings in both locations. We believe the estimated capital expenditures will continue to be funded from operations, and may be supplemented by short-term borrowings, if required.

Financing Activities.Cash flows used in financing activities totaled $6.4 million for the nine months endedJune 30, 2012, as compared to cash flows used in financing activities of $2.4 million for the nine months endedJuly 2, 2011. Cash flows used in financing activities for the nine months endedJune 30, 2012 were comprised primarily of payments on debt, partially offset by debt proceeds and proceeds from the exercise of stock options. Cash flows used in financing activities for the nine months endedJuly 2, 2011 were comprised primarily of purchases of common stock and payments on debt, partially offset by debt proceeds and proceeds from the exercise of stock options.

On May 15, 2012, the Company entered into a five-year, $250 million senior unsecured credit facility that terminates on May 15, 2017 (the “New Credit Facility”). The New Credit Facility includes a $160 million revolving credit facility and a $90 million term loan. The revolving credit facility potentially may be increased by $100 million (the "increase option") to $260 million generally by mutual agreement of the Company, the lenders, the letter of credit issuers and the administrative agent named in the related credit agreement (the "Credit Agreement"), subject to certain customary conditions. The New Credit Facility was used to refinance the Company's then-existing $100 million senior unsecured revolving credit facility (no amounts were outstanding as of May 15, 2012) and its $150 million senior unsecured term loan (balance of $90.0 million as of May 15, 2012), both of which were scheduled to mature on April 4, 2013 (the “Prior Credit Facility”), and for general corporate purposes.

22

The financial covenants (as defined under the New Credit Facility) require that the Company maintain, as of each fiscal quarter end, a maximum total leverage ratio and a minimum interest coverage ratio. As of June 30, 2012, the Company was in compliance with all covenants of the New Credit Facility. Borrowings under the New Credit Facility, at the Company's option, bear interest at a defined base rate or the LIBOR rate plus, in each case, an applicable margin based upon the Company's leverage ratio as defined in the Credit Agreement. 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% or the base rate plus 0%. We are also required to pay an annual commitment fee on the unused revolver credit commitment based on our leverage ratio; the fee was 0.20% as of June 30, 2012.

During the third quarter of fiscal 2011, we entered into a Note Purchase Agreement (the “Note Purchase Agreement”) for $175 million in principal amount of 5.20% Senior Notes, due June 15, 2018 (the “Notes”). We issued $100 million in principal amount of the Notes on April 21, 2011, and the remaining $75 million on June 15, 2011. As of June 30, 2012 we had notes outstanding of $175.0 million.

The Note Purchase Agreement contains certain financial covenants, which include a maximum total leverage ratio, a minimum interest coverage ratio and a minimum net worth test, all as defined in the agreements. As of June 30, 2012, we were in compliance with all debt covenants.

The New Credit Facility and Note Purchase Agreement allow 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) exists at the time of, or would be caused by, the dividend payment or the share repurchases. We have not paid cash dividends in the past and do not currently anticipate paying them in the future. However, we evaluate from time to time potential uses of excess cash, which in the future may include share repurchases, a special dividend or recurring dividends.

Based on current expectations, we believe that our projected cash flows from operations, available cash and cash equivalents, the New Credit Facility, and our leasing capabilities should be sufficient to meet our working capital and fixed capital requirements for the next twelve months and for the foreseeable future. Further, $160 million of committed credit is currently available under the New Credit Facility, with another $100 million potentially available pursuant to the increase option described above. If our future financing needs increase, we may need to arrange additional debt or equity financing. Accordingly, we evaluate and consider from time to time various financing alternatives to supplement our financial resources. However, particularly due to the current uncertainty of the credit and financial markets, we cannot be assured that we will be able to make any such arrangements on acceptable terms.

Total Contractual Cash Obligations	$	819.7	$	270.5	$	228.9	$	44.2	$	276.1

1) On May 15, 2012, we entered into the New Credit Facility and immediately funded a term loan for $90 million. As of June 30, 2012, the outstanding balance was $86.3 million. The amounts listed above include interest; see Note 5 in Notes to Consolidated Financial Statements for further information.

2) During the third quarter of fiscal 2011, we entered into the Note Purchase Agreement and issued $175 million in principal amount of notes. The amounts listed above include interest; see Note 5 in Notes to Consolidated Financial Statements for further information.

3) As of June 30, 2012, purchase obligations consist of purchases of inventory and equipment in the ordinary course of business.

4) As of June 30, 2012, other long-term obligations on the balance sheet included deferred compensation obligations to certain of our former and current executive officers, as well as other key employees, and an asset retirement obligation. We have excluded from the above table the impact of approximately $7.9 million, as of June 30, 2012, related to unrecognized income tax benefits. The Company cannot make reliable estimates of the future cash flows by period related to this obligation.

5) As of June 30, 2012, other long-term obligations not on the balance sheet consisted of a commitment for salary continuation in the event employment of one executive officer of the Company is terminated without cause as well as commitments to build new manufacturing facilities in Neenah, Wisconsin and Oradea, Romania.

DISCLOSURE ABOUT CRITICAL ACCOUNTING POLICIES

Our accounting policies are disclosed in our 2011 annual report on Form 10-K. During the first three quarters of fiscal 2012, there were no material changes to these policies.

NEW ACCOUNTING PRONOUNCEMENTS

See Note 15 in Notes to Condensed Consolidated Financial Statements for further information regarding new accounting pronouncements.

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 partially offsets the effects of changes in foreign currency exchange rates. We typically use 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. Our percentages of transactions denominated in currencies other than the U.S. dollar for the indicated periods were as follows:

	Three Months Ended				Nine Months Ended
	June 30, 2012		July 2, 2011		June 30, 2012		July 2, 2011
Net sales	5	%	6	%	5	%	6	%
Total costs	14	%	15	%	14	%	14	%

The Company has evaluated the potential foreign currency exchange rate risk on transactions denominated in currencies other than the U.S. Dollar for the periods presented above. Based on the Company’s overall currency exposure, as of June 30, 2012 a 10 percent change in the value of the U.S. Dollar relative to our other transactional currencies would not have a material effect on the Company’s financial position, results of operations, or cash flows.

Interest Rate Risk

We have financial instruments, including cash equivalents, which are sensitive to changes in interest rates. We consider the use of interest-rate swaps based on existing market conditions and have entered into interest rate swaps for $86.3 million in term loans, as described in Note 6 in Notes to Condensed Consolidated Financial Statements. As with any agreement of this type, our interest rate swap agreements are subject to the further risk that the counterparties to these agreements may fail to comply with their obligations thereunder.

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 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 New Credit Facility under which we borrowed $90 million. Through the use of interest rate swaps, as described above, we have fixed the basis on which we pay interest, and the borrowings under the Note Purchase Agreement are based on a fixed interest rate, thus eliminating much of our interest rate risk.

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 (“SEC”) is recorded, processed, summarized and reported on a timely basis. The Company’s principal executive officer and principal financial officer have reviewed and evaluated, with the participation of the Company’s management, the Company’s disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) as of the end of the period covered by this report (the “Evaluation Date”). Based on such evaluation, the chief executive officer and chief financial officer have concluded that, as of the Evaluation Date, the Company’s disclosure controls and procedures are effective (a) in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by the Company in the reports the Company files or submits under the Exchange Act, and (b) in assuring that information is accumulated and communicated to the Company’s management, including the chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting: During the third quarter of fiscal 2012, there have been no changes to the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Limitations on the Effectiveness of Controls: Our management, including our chief executive officer and chief financial officer, does not expect that our disclosure controls and internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple errors or mistakes. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, a control may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Notwithstanding the foregoing limitations on the effectiveness of controls, we have nonetheless reached the conclusion that the Company’s disclosure controls and procedures are effective at the reasonable assurance level.

PART II. OTHER INFORMATION

ITEM 1.    Legal Proceedings

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. During September 2010, the Company reported errors relating to import trade activity from July 2004 to the date of Plexus' report. CBP has indicated that on-site fieldwork for the audit was completed as of June 2011, and 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. We recorded an accrual in other current accrued liabilities in the first quarter of fiscal 2010 when the amount became estimable and probable, which was not material to the financial statements. 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.

The Company is a 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.

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 (together “Plexus,” the “Company,” or “we”) without audit and pursuant to the rules and regulations of the United States (“U.S.”) 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 June 30, 2012 and October 1, 2011, and the results of operations for the three and nine months endedJune 30, 2012 and July 2, 2011, and the cash flows for the same nine month periods.

Certain information and footnote disclosures, normally included in financial statements prepared in accordance with generally accepted accounting principles, have been condensed or omitted pursuant to the SEC’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 2011 Annual Report on Form 10-K.

The Company’s reportable segments consist of the “Americas” (“AMER”) segment, “Asia-Pacific” (“APAC”) segment and “Europe, Middle East, and Africa” (“EMEA”) segment. Refer to Note 10, "Business Segment and Major Customer Information," for further details on reportable segments.

Revision of prior period financial statements

During the second quarter of fiscal 2012, the Company revised its previously issued financial statements as a result of a correction to the classification of upfront payments made for land use rights in certain foreign countries. Refer to Note 16, "Revision of Prior Period Financial Statements," for further discussion of these revisions.

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 and are classified as Level 1 in the fair level hierarchy described below.

Fair Value of Financial Instruments

The Company holds financial instruments consisting of cash and cash equivalents, accounts receivable, accounts payable, debt, derivatives, and capital lease obligations. The carrying values of cash and cash equivalents, accounts receivable, accounts payable, derivatives, 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 long-term debt was $259.0 million and $274.3 million as of June 30, 2012 and October 1, 2011, respectively. The carrying value of the Company’s long-term debt was $261.3 million and $272.5 million as of June 30, 2012 and October 1, 2011, respectively. The Company uses quoted market prices when available or discounted cash flows to calculate the fair value of its debt. If measured at fair value in the financial statements, long-term debt (including the current portion) would be classified as Level 2 in the fair value hierarchy described below. Refer to Note 6, "Derivatives and Fair Value Measurements," for further details on derivatives.

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.

Business Combination

BUSINESS COMBINATION

In the second quarter of fiscal 2012, Plexus and Kontron AG (“Kontron”) entered into a strategic manufacturing arrangement, and completed the related asset purchase transaction described below. Under this arrangement, Kontron transitioned all manufacturing of its Kontron Design Manufacturing Services (M) Sdn. Bhd. subsidiary (“KDMS”) located in Penang, Malaysia to Plexus facilities in Penang. Plexus acquired the inventory and equipment of KDMS for an initial purchase price of $35.2 million, which was paid with cash on-hand, and hired substantially all of KDMS's employees. No real estate was included in this transaction. This transaction has been accounted for as a business combination. The purchase price was allocated primarily to inventory and equipment. An identifiable intangible asset related to a customer relationship was recorded within other non-current assets in the Company's accompanying Condensed Consolidated Balance Sheets as a result of the arrangement and will be amortized on a straight-line basis over a two year period. Under this arrangement, Kontron also committed to approximately $100 million of incremental revenue annually for two years. In the three months ended June 30, 2012, the Company recorded a $1.1 million purchase price adjustment as a result of a post closing adjustment, for which the cash was received in the third quarter of fiscal 2012. The purchase price allocation may be further adjusted to reflect final valuation of the assets acquired. Assuming this transaction had been made at the beginning of any period presented, the consolidated pro forma results would not be materially different from reported results.

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. During September 2010, the Company reported errors relating to import trade activity from July 2004 to the date of Plexus' report. CBP has indicated that on-site fieldwork for the audit was completed as of June 2011, and 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. We recorded an accrual in other current accrued liabilities in the first quarter of fiscal 2010 when the amount became estimable and probable, which was not material to the financial statements. 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.

For the three and nine months endedJune 30, 2012, stock options and stock-settled stock appreciation rights ("SARS") for approximately 1.4 million and 1.3 million shares, respectively, 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 Company's common shares and, therefore, their effect would be anti-dilutive. For both the three and nine months endedJune 30, 2012, restricted stock units (“RSUs”) of approximately 0.1 million units were outstanding but were not included in the computation of diluted earnings per share because their effect would have been anti-dilutive.

For the three and nine months endedJuly 2, 2011, stock options and stock-settled SARs for approximately 1.1 million and 1.2 million shares, respectively, 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 Company's common shares and, therefore, their effect would be anti-dilutive. For three and nine months endedJuly 2, 2011, none of the RSUs outstanding had an anti-dilutive effect.

Derivatives And Fair Value Measurements

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 foreign currency obligations. 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.

The Company’s Mexican operations were parties to forward exchange contracts all of which were settled as of June 30, 2012. The total fair value of these forward contracts was a $1.0 millionliability as of October 1, 2011.

During the second quarter of fiscal 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 the Company’s fourth facility in Malaysia; these contracts were settled as of the end of the first quarter of fiscal 2012. The total fair value of these forward contracts was a $0.1 millionliability as of October 1, 2011.

The Company’s Malaysian operations have also entered into forward exchange contracts on a rolling basis with a total notional value of $54.1 million as of June 30, 2012. These forward contracts will fix the exchange rates on foreign currency cash used to pay a portion of local currency expenses. The total fair value of these forward contracts was a $1.4 millionliability as of June 30, 2012 and a $1.5 millionliability as of October 1, 2011.

During fiscal 2011, the Company entered into 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. During the third quarter of fiscal 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 is being amortized over the seven year term of the related debt.

The Company entered into three interest rate swap contracts related to the $150 million in term loans under its Prior Credit Facility that had an initial total notional value of $150 million and mature on April 4, 2013. These interest rate swap contracts continued into the New Credit Facility and pay the Company variable interest at the three month LIBOR rate, and the Company pays 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 originally entered into to convert $150 million of the variable rate term loan under the Prior 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 a $2.5 millionliability as of June 30, 2012 and a $5.2 millionliability as of October 1, 2011. As of June 30, 2012, the total remaining combined notional amount of the Company’s three interest rate swaps was $86.3 million.

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.

Segment Reporting [Abstract]

Business Segment And Major Customer Information

BUSINESS SEGMENT 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.

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 nine months endedJune 30, 2012 and July 2, 2011, respectively, were as follows (in thousands):

Income Tax Expense (Benefit) [Abstract]

Income Taxes

INCOME TAXES

Income tax expense for the three and nine months endedJune 30, 2012 was $1.9 million and $6.1 million, respectively. The effective tax rates for the three and nine months endedJune 30, 2012 were 8 and 9 percent, respectively. 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 APAC segment due to tax holidays in Penang, Malaysia and Xiamen, China.

Income tax expense for the three and nine months endedJuly 2, 2011 was $0.7 million and $2.2 million, respectively. The effective tax rates for both the three and nine months endedJuly 2, 2011 were 3 percent.

As of June 30, 2012, there was no material change in the amounts recorded for uncertain tax positions as compared to the fiscal 2011 year end. 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 nine months endedJune 30, 2012 and July 2, 2011 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. The Company is currently under examination by taxing authorities in the U.S. for fiscal years 2008 through 2010 and is not undergoing any tax examinations in any of its major foreign jurisdictions. The U.S. examination may be resolved within the next twelve months, but at this time it is not possible to estimate the amount of the effects of any changes to the Company's previously recorded uncertain tax positions.

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. As of June 30, 2012, there was no material change in the valuation allowance as compared to the fiscal 2011 year end. Despite losses in fiscal years 2009-2011 in the U.S. tax jurisdiction, the Company’s U.S. operations generated income for the three and nine months endedJune 30, 2012. Based on the weight of all the evidence, both positive and negative, it is more likely than not that the Company will be able to utilize its U.S. net deferred tax assets and no valuation allowance is warranted. However, if the Company’s U.S. operations cannot sustain forecasted profitability, there may be a need to provide a valuation allowance on the Company’s net U.S. deferred tax assets which approximate $21.4 million as of June 30, 2012.

Guarantees

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 2011 and for the nine months endedJune 30, 2012 (in thousands):

Limited warranty liability, as of October 2, 2010	$	4,055

Revision Of Prior Period Financial Statements

REVISION OF PRIOR PERIOD FINANCIAL STATEMENTS

In the second quarter of fiscal 2012, the Company identified prior period errors in its consolidated financial statements related to the Condensed Consolidated Balance Sheets and Condensed Consolidated Statements of Cash Flows classification of upfront payments made for land use rights. Specifically, the Company had historically accounted for the upfront payments for the land use rights as capital leases within property, plant and equipment and as investing activities in the Condensed Consolidated Statements of Cash Flows. The Company has determined that the upfront payments made for land use rights should have been reflected as an operating lease within other long-term assets on the Condensed Consolidated Balance Sheets and as operating activities within the Condensed Consolidated Statements of Cash Flows. There was no impact of the error corrections on the Consolidated Statements of Operations. In evaluating whether the Company’s previously issued consolidated financial statements were materially misstated, the Company considered the guidance in Accounting Standard Codification (ASC) Topic 250, Accounting Changes and Error Corrections, ASC Topic 250-10-S99-1, Assessing Materiality, and ASC Topic 250-10-S99-2, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements. The Company concluded these errors were not material individually or in the aggregate to any of the prior reporting periods. The impact of these corrections to the applicable prior periods are reflected in the financial information and notes herein and will be reflected in future filings containing affected financial information. The impact of these revisions on the financial statements included in the Company’s 2011 Annual Report on Form 10-K and previously filed 2012 and 2011 Forms 10-Q is described below. In addition, footnotes impacted by the above error will also be revised in future filings.

Revisions to the Condensed Consolidated Balance Sheets reflect a decrease in property, plant and equipment and an increase to other long-term assets in the amounts of $17.6 million, $17.7 million, and $14.8 million as of December 31, 2011, October 1, 2011, and October 2, 2010, respectively.

During the fourth quarter of fiscal 2010 and the first quarter of fiscal 2011, the Company made upfront payments for land use rights in the amount of $9.6 million and $3.2 million, respectively. These payments were classified as capital expenditures within investing activities in the Consolidated Statements of Cash Flows for fiscal 2010 and 2011 and each quarterly period in fiscal 2011, respectively. The classification of these payments has been corrected to properly reflect these amounts as operating cash outflows rather than investing cash outflows in the financial information included herein and will be corrected in the relevant periods in future filings. There will also be inconsequential revisions to depreciation and change in prepaid expense and other within the operating activities section of the Consolidated Statements of Cash Flows in future filings. The revised totals for operating cash flows and investing cash flows are $158.5 million and $(68.7) million for fiscal 2011, $(7.6) million and $(64.8) million for fiscal 2010, and $(24.3) million and $(10.0) million, $48.4 million and $(24.2) million, and $64.0 million and $(42.1) million during the three, six, and nine months ended for fiscal 2011, respectively.

Debt Instruments [Abstract]

Debt

DEBT

On May 15, 2012, the Company entered into a five-year, $250 million senior unsecured credit facility that terminates on May 15, 2017 (the “New Credit Facility”). The New Credit Facility includes a $160 million revolving credit facility and a $90 million term loan. The revolving credit facility may be increased by $100 million (the "increase option") to $260 million generally by mutual agreement of the Company, the lenders, the letter of credit issuers and the administrative agent named in the related credit agreement (the "Credit Agreement"), subject to certain customary conditions. The New Credit Facility was used to refinance the Company's then-existing $100 million senior unsecured revolving credit facility (no amounts were outstanding as of May 15, 2012) and its $150 million senior unsecured term loan (balance of $90.0 million as of May 15, 2012), both of which were scheduled to mature on April 4, 2013 (the “Prior Credit Facility”), and for general corporate purposes.

The financial covenants (as defined under the New Credit Facility) require that the Company maintain, as of each fiscal quarter end, a maximum total leverage ratio and a minimum interest coverage ratio. As of June 30, 2012, the Company was in compliance with all covenants of the New Credit Facility. Borrowings under the New Credit Facility, at the Company's option, bear interest at a defined base rate or the LIBOR rate plus, in each case, an applicable margin based upon the Company's leverage ratio as defined in the Credit Agreement. 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% or base rate plus 0%. The Company is also required to pay an annual commitment fee on the unused revolver credit commitment based on the Company's leverage ratio; the fee was 0.20% as of June 30, 2012.

In connection with the New Credit Facility, the Company incurred approximately $0.9 million in new debt issuance costs, which are being amortized over the five-year term of the New Credit Facility. In addition, at the time of the refinancing the Company expensed approximately $0.2 million related to the transactions.

The Company repaid $3.75 million of term loans outstanding on its New Credit Facility in the third quarter of fiscal 2012. During each of the first two quarters of fiscal 2012, the Company repaid $3.75 million of term loans outstanding on its Prior Credit Facility. As of June 30, 2012, the Company had term loan borrowings of $86.3 million outstanding and no revolving borrowings under the New Credit Facility.

During each of the first three quarters of fiscal 2011, the Company repaid $3.75 million each quarter of term loans outstanding under its Prior Credit Facility. As of July 2, 2011, the Company had term loan borrowings of $101.3 million outstanding and no revolving borrowings under the Prior Credit Facility.

During the third quarter of fiscal 2011, the Company entered into a Note Purchase Agreement with certain institutional investors and issued $175 million in principal of 5.20% Senior Notes, due on June 15, 2018 (the “Notes”). The Company had $175 million principal of Notes outstanding as of both June 30, 2012 and July 2, 2011.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

New Accounting Pronouncements

NEW ACCOUNTING PRONOUNCEMENTS

In December 2011, the Financial Accounting Standards Board (“FASB”) issued an amendment to disclosures about offsetting assets and liabilities. The amended standard requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. An entity is required to apply the amendments for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. An entity should provide the disclosures required by those amendments retrospectively for all comparative periods presented. The adoption of this guidance is not anticipated to have a material impact on the Company’s consolidated results of operations, financial position and cash flows.

In June 2011, the FASB issued an amendment to comprehensive income guidance, which eliminates the option to present other comprehensive income (“OCI”) and its components in the statement of shareholders’ equity. The Company can elect to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. Under the two-statement approach, the first statement would include the components of net income, and the second statement would include the components of OCI. This guidance is effective for financial statements issued for fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption of this guidance is not anticipated to have a material impact on the Company’s consolidated results of operations, financial position and cash flows.
