PLEXUS CORP. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

FOR THE THREE MONTHS ENDED MARCH 30, 2024 AND APRIL 1, 2023

Unaudited

1.    Basis of Presentation

Basis of Presentation:

The accompanying Condensed Consolidated Financial Statements included herein have been prepared by Plexus Corp. and its subsidiaries (together “Plexus” or the “Company”) without audit and pursuant to the rules and regulations of the United States (“U.S.”) Securities and Exchange Commission (“SEC”). The accompanying Condensed Consolidated Financial Statements reflect all adjustments, which include normal recurring adjustments necessary for the fair statement of the condensed consolidated financial position of the Company as of March 30, 2024 and September 30, 2023, the results of operations and shareholders' equity for the three and six months ended March 30, 2024 and April 1, 2023, and the cash flows for the same six month periods.

The Company’s fiscal year ends on the Saturday closest to September 30. The Company uses a “4-4-5” weekly accounting system for the interim periods in each quarter. Each quarter, therefore, ends on a Saturday at the end of the 4-4-5 period. Periodically, an additional week must be added to the fiscal year to re-align with the Saturday closest to September 30. All fiscal quarters presented herein included 13 weeks.

Certain information and footnote disclosures, normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"), 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 2023 Annual Report on Form 10-K.

The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in the Condensed Consolidated Financial Statements and notes thereto. The Company has considered information available as of the date of issuance of these financial statements and, other than the information disclosed in Note 16, "Subsequent Event", is not aware of any specific events or circumstances that would require an update to its estimates or judgments or a revision of the carrying value of its assets or liabilities. These estimates may change as new events occur and additional information becomes available. Actual results could differ materially from these estimates.

Reclassification:

Certain prior year amounts in the consolidated financial statements and notes thereto have been reclassified related to advanced payments from customers to conform to the current year's presentation.

Recently Adopted Accounting Pronouncements:

In September 2022, the FASB issued ASU 2022-04 Supplier Finance Programs (Subtopic 405-50), which requires enhanced disclosures about supplier finance programs. The Company adopted this guidance during the first quarter of fiscal 2024 with no material impact to the Company's Consolidated Financial Statements; however, the impact of the new standard on future periods will depend on the facts and circumstances of future transactions.

Recently Issued Accounting Pronouncements Not Yet Adopted:

In March 2024, the SEC adopted final rules to require registrants to disclose certain climate-related information in registration statements and annual reports. The SEC stayed its climate disclosure rules to facilitate the orderly judicial resolution of pending legal challenges. We are currently evaluating the impacts that the SEC's rule will have on our financial statement disclosures.

In November 2023, the FASB issued ASU 2023-07 Segment Reporting (Topic 280), which requires enhanced disclosures for segment reporting. The guidance is effective for the Company beginning in the first quarter of fiscal 2025. We are currently evaluating the impact that the updated standard will have on our financial statement disclosures.

In December 2023, the FASB issued ASU 2023-09 Income Taxes (Topic 740), which requires enhanced disclosures for income taxes. The guidance is effective for the Company beginning in the first quarter of fiscal 2026. Early adoption is permitted. We are currently evaluating the impact that the updated standard will have on our financial statement disclosures.

7

The Company does not believe that any other recently issued accounting standards will have a material impact on its Consolidated Financial Statements or apply to its operations.

2.    Inventories

The total amount of customer deposits related to inventory and included within advanced payments from customers on the accompanying Condensed Consolidated Balance Sheets as of March 30, 2024 and September 30, 2023 was $536.9 million and $590.2 million, respectively.

3.    Debt, Finance Lease and Other Financing Obligations

	March 30, 2024		September 30, 2023
4.05% Senior Notes, due June 15, 2025	$	100,000	$	100,000

Total obligations	437,989		431,058
Less: current portion	(245,964)		(240,205)
Long-term debt, finance lease and other financing obligations, net of current portion	$	192,025	$	190,853

As of March 30, 2024, the Company was in compliance with covenants for all debt agreements.

During the six months ended March 30, 2024, the highest daily borrowing under the Company's 5-year senior unsecured revolving credit facility (referred to as the "Credit Facility") was $376.0 million; the average daily borrowings were $300.3 million. During the six months ended April 1, 2023, the highest daily borrowing was $412.0 million; the average daily balance was $344.5 million.

The fair value of the Company’s debt, excluding finance lease and other financing obligations, was $383.6 million and $374.3 million as of March 30, 2024 and September 30, 2023, respectively. The carrying value of the Company's debt, excluding finance lease and other financing obligations, was $389.0 million and $383.0 million as of March 30, 2024 and September 30, 2023, respectively. If measured at fair value in the financial statements, the Company's debt would be classified as Level 2 in the fair value hierarchy. Refer to Note 4, "Derivatives and Fair Value Measurements," for further information regarding the Company's fair value calculations and classifications.

4.    Derivatives and Fair Value Measurements

All derivatives are recognized in the accompanying Condensed Consolidated Balance Sheets at their estimated fair value. The Company uses derivatives to manage the variability of foreign currency obligations. The Company has cash flow hedges related to forecasted foreign currency obligations, in addition to non-designated hedges to manage foreign currency exposures associated with certain foreign currency denominated assets and liabilities. The Company does not enter into derivatives for speculative purposes.

The Company designates some foreign currency exchange contracts as cash flow hedges of forecasted foreign currency expenses. Changes in the fair value of the derivatives that qualify as cash flow hedges are recorded in "Accumulated other comprehensive loss" in the accompanying Condensed Consolidated Balance Sheets until earnings are affected by the variability of the cash flows. In the next twelve months, the Company estimates that $1.8 million of unrealized gains, net of tax, related to cash flow hedges will be reclassified from other comprehensive income into earnings. Changes in the fair value of the non-designated derivatives related to recognized foreign currency denominated assets and liabilities are recorded in "Miscellaneous, net" in the accompanying Condensed Consolidated Statements of Comprehensive Income.

The Company enters into forward currency exchange contracts for its operations in certain jurisdictions in the AMER and APAC segments on a rolling basis. The Company had cash flow hedges outstanding with a notional value of $275.0 million as of March 30, 2024, and a notional value of $215.4 million as of September 30, 2023. These forward currency contracts fix the exchange rates for the settlement of future foreign currency obligations that have yet to be realized. The total fair value of the forward currency exchange contracts was a $1.8 million asset as of March 30, 2024 and a $5.0 million liability as of September 30, 2023.

The Company had additional forward currency exchange contracts outstanding as of March 30, 2024, with a notional value of $220.7 million; there were $145.5 million of such contracts outstanding as of September 30, 2023. The Company did not designate these derivative instruments as hedging instruments. The net settlement amount (fair value) related to these contracts is recorded on the Condensed Consolidated Balance Sheets as either a current or long-term asset or liability, depending on the term, and as an element of "Miscellaneous, net" in the Condensed Consolidated Statements of Comprehensive Income. The total fair value of these derivatives was a $0.3 million liability as of March 30, 2024 and a $1.3 million liability as of September 30, 2023.

Fair Value Measurements:

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 Company uses quoted market prices when available or discounted cash flows to calculate fair value. 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.

The following table lists the fair values of the Company’s derivatives as of March 30, 2024 and September 30, 2023 by input level:

The fair value of 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. Inputs in the fair value of the foreign currency forward contracts include prevailing forward and spot prices for currency.

5.    Income Taxes

Income tax expense for the three and six months ended March 30, 2024 was $2.7 million and $8.4 million compared to $7.0 million and $14.2 million for the three and six months ended April 1, 2023.

The effective tax rates for the three and six months ended March 30, 2024 were 14.4% and 15.5%, respectively, compared to the effective tax rate of 14.6% for the three and six months ended April 1, 2023. The increase for the six months ended March 30, 2024 compared to the six months ended April 1, 2023 is primarily due to a change in the geographic distribution of pre-tax book income.

The amount of unrecognized tax benefits recorded for uncertain tax positions increased by $1.0 million for the three months ended March 30, 2024. The Company recognizes accrued interest and penalties on uncertain tax positions as a component of income tax expense. The amount of interest and penalties recorded for the three and six months ended March 30, 2024 was not material.

One or more uncertain tax positions may be settled within the next 12 months. Settlement of these matters is not expected to have a material effect on the Company's consolidated results of operations, financial position and cash flows. The Company is not currently under examination by taxing authorities in the U.S. or any foreign jurisdiction.

The Company maintains valuation allowances when it is more likely than not that all or a portion of a net deferred tax asset will not be realized. During the three months ended March 30, 2024, the Company continued to record a full valuation allowance against its net deferred tax assets in certain jurisdictions within the EMEA and APAC segments and a partial valuation against its net deferred tax assets in certain jurisdictions within the AMER segment, as it was more likely than not that these assets would not be fully realized based primarily on historical performance. The Company will continue to provide a valuation allowance against its net deferred tax assets in each of the applicable jurisdictions going forward until it determines it is more likely than not that the deferred tax assets will be realized.

6.    Earnings Per Share

The following is a reconciliation of the amounts utilized in the computation of basic and diluted earnings per share for the three and six months ended March 30, 2024 and April 1, 2023 (in thousands, except per share amounts):

	Three Months Ended				Six Months Ended
	March 30, 2024		April 1, 2023		March 30, 2024		April 1, 2023
Net income	$	16,239	$	40,844	$	45,454	$	83,034
Basic weighted average common shares outstanding	27,542		27,661		27,513		27,650
Dilutive effect of share-based awards and options outstanding	387		523		469		623
Diluted weighted average shares outstanding	27,929		28,184		27,982		28,273
Earnings per share:
Basic	$	0.59	$	1.48	$	1.65	$	3.00
Diluted	$	0.58	$	1.45	$	1.62	$	2.94

For the three and six months ended March 30, 2024 and April 1, 2023, share-based awards for less than 0.1 million shares were not included in the computation of diluted earnings per share as they were antidilutive awards.

See also Note 12, "Shareholders' Equity," for information regarding the Company's share repurchase plans.

7.    Leases

The components of lease expense for the three and six months ended March 30, 2024 and April 1, 2023 indicated were as follows (in thousands):

	Three Months Ended				Six Months Ended
	March 30, 2024		April 1, 2023		March 30, 2024		April 1, 2023
Finance lease expense:
Amortization of right-of-use assets	$	1,506	$	1,952	$	3,024	$	3,566
Interest on lease liabilities	1,375		1,260		2,697		2,532
Operating lease expense	2,652		2,736		5,270		5,342

Total	$	6,698	$	7,778	$	14,218	$	15,036

Based on the nature of the right-of-use ("ROU") asset, amortization of finance lease ROU assets, operating lease expense and other lease expense are recorded within either cost of goods sold or selling and administrative expenses and interest on finance lease liabilities is recorded within interest expense on the Condensed Consolidated Statements of Comprehensive Income. Other lease expense includes lease expense for leases with an estimated total term of twelve months or less and variable lease expense related to variations in lease payments as a result of a change in factors or circumstances occurring after the lease possession date.

As of March 30, 2024, we have a lease signed but not yet commenced totaling payments of $14.6 million. This lease will commence in the next twelve months, with a lease term of 60 years.

8.    Share-Based Compensation

At the 2024 Annual Meeting of Shareholders on February 14, 2024, the Company's shareholders approved the Plexus Corp. 2024 Omnibus Incentive Plan (the "2024 Plan"). The 2024 Plan is a stock and cash-based incentive plan, and includes provisions by which the Company may grant executive officers, employees and directors stock options, stock appreciation rights ("SARs"), restricted stock (including restricted stock units ("RSUs")), performance stock awards (including performance stock units ("PSUs")), other stock awards and cash incentive awards. Similar awards were offered under its predecessor, the Plexus Corp. 2016 Omnibus Incentive Plan (the "2016 Plan"), which is no longer being used for grants; however, outstanding awards granted under the 2016 Plan and its predecessor continue until vesting, exercise, forfeiture or expiration.

The Company recognized $7.1 million and $12.4 million of compensation expense associated with share-based awards for the three and six months ended March 30, 2024, respectively, and $5.9 million and $11.7 million for the three and six months ended April 1, 2023, respectively.

9.    Litigation

The Company is party to lawsuits in the ordinary course of business. We record provisions in the consolidated financial statements for pending legal matters when we determine that an unfavorable outcome is probable, and the amount of the loss can be reasonably estimated.

Management does not believe that any such proceedings, individually or in the aggregate, will have a material positive or adverse effect on the Company’s consolidated financial position, results of operations or cash flows. However, legal proceedings and regulatory and governmental matters are subject to inherent uncertainties, and unfavorable rulings or other events could occur. Unfavorable resolutions could involve substantial fines, civil or criminal penalties, and other expenditures.

10.    Reportable Segments

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 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 the segments are attributed to the region in which the product is manufactured or the 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. A segment’s operating income includes its net sales less cost of sales and selling and administrative expenses, but excludes corporate and other expenses. Corporate and other expenses primarily represent corporate selling and administrative expenses, and restructuring and other charges, 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 segments are the same as for the Company taken as a whole.

Information about the Company’s three reportable segments for the three and six months ended March 30, 2024 and April 1, 2023 is as follows (in thousands):

11.    Guarantees

The Company offers certain indemnifications under its customer manufacturing agreements. In the normal course of business, the Company may from time to time be obligated to indemnify its customers or its customers’ customers against damages or liabilities arising out of the Company’s negligence, misconduct, breach of contract, or infringement of third-party intellectual property rights. Certain agreements have extended broader indemnification, and while most agreements have contractual limits, some do not. However, the Company generally does not provide for such indemnities and seeks indemnification from its customers for damages or liabilities arising out of the Company’s adherence to customers’ specifications or designs or use of materials furnished, or directed to be used, by its customers. The Company does not believe its obligations under such indemnities are material.

In the normal course of business, the Company also provides its customers a limited warranty covering workmanship, and in some cases materials, on products manufactured by the Company. Such warranty generally provides that products will be free from defects in the Company’s workmanship and meet mutually agreed-upon specifications for periods generally ranging from 12 months to 24 months. 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 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 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 the six months ended March 30, 2024 and April 1, 2023 (in thousands):

	Six Months Ended
	March 30, 2024		April 1, 2023
Reserve balance, beginning of period	$	5,821	$	6,925
Accruals for warranties issued during the period	1,726		1,254
Settlements (in cash or in kind) during the period	(476)		(2,243)
Reserve balance, end of period	$	7,071	$	5,936

12.    Shareholders' Equity

On August 18, 2022, the Board of Directors approved a share repurchase program under which the Company is authorized to repurchase up to $50.0 million of its common stock (the "2023 Program"). The 2023 Program completed in February 2024. During the three and six months ended March 30, 2024, the Company repurchased 59,277 shares under this program for $5.7 million at an average price of $95.59 per share. During the three months ended April 1, 2023, the Company repurchased 125,639 shares under this program for $12.4 million at an average price of $98.75 per share. During the six months ended April 1, 2023, the Company repurchased 241,362 shares under this program for $23.9 million at an average price of $98.93 per share.

On January 16, 2024, the Company announced a share repurchase program authorized by the Board of Directors under which the Company is authorized to repurchase up to $50.0 million of its common stock (the "2024 Program"). The 2024 Program became effective upon completion of the 2023 Program, which occurred in February 2024, and has no expiration. During the three and six months ended March 30, 2024, the Company repurchased 126,850 shares under this program for $11.9 million at an average price of $93.83 per share. As of March 30, 2024, $38.1 million of authority remained under the 2024 Program.

All shares repurchased under the aforementioned programs were recorded as treasury stock.

13.    Trade Accounts Receivable Sale Programs

The Company has Master Accounts Receivable Purchase Agreements with MUFG Bank, New York Branch (formerly known as The Bank of Tokyo-Mitsubishi UFJ, Ltd.) (the "MUFG RPA"), HSBC Bank (China) Company Limited, Xiamen branch (the "HSBC RPA") and other unaffiliated financial institutions, under which the Company may elect to sell receivables at a discount. All facilities are uncommitted facilities. The maximum facility amount under the MUFG RPA is $340.0 million. The maximum facility amount under the HSBC RPA is $70.0 million. The MUFG RPA will be automatically extended each year unless any party gives no less than 10 days prior notice that the agreement should not be extended. The terms of the HSBC RPA are generally consistent with the terms of the MUFG RPA.

Transfers of receivables under the programs are accounted for as sales and, accordingly, receivables sold under the programs are excluded from accounts receivable on the Condensed Consolidated Balance Sheets and are reflected as cash provided by operating activities on the Condensed Consolidated Statements of Cash Flows. Proceeds from the transfer reflect the face value of the receivables less a discount. The sale discount is recorded within "Miscellaneous, net" in the Condensed Consolidated Statements of Comprehensive Income in the period of the sale. The Company continues servicing receivables sold and performing all accounts receivable administrative functions, in exchange receives a servicing fee, under both the MUFG RPA and HSBC RPA. Servicing fees related to trade accounts receivable programs recognized during the three and six months ended March 30, 2024 and April 1, 2023 were not material.

The Company sold $213.8 million and $225.7 million of trade accounts receivable under these programs, or their predecessors, during the three months ended March 30, 2024 and April 1, 2023, respectively, in exchange for cash proceeds of $211.1 million and $222.9 million, respectively.

The Company sold $437.4 million and $411.3 million of trade accounts receivable under these programs, or their predecessors, during the six months ended March 30, 2024 and April 1, 2023, respectively, in exchange for cash proceeds of $432.1 million and $406.5 million, respectively.

As of March 30, 2024 and September 30, 2023, $217.8 million and $220.5 million, respectively, of accounts receivables sold under trade accounts receivable programs and subject to servicing by the Company remained outstanding and had not yet been collected by MUFG Bank or HSBC Bank.

14.    Revenue from Contracts with Customers

Revenue is recognized over time for arrangements with customers for which: (i) the Company's performance does not create an asset with an alternative use to the Company, and (ii) the Company has an enforceable right to payment, including reasonable profit margin, for performance completed to date. Revenue recognized over time is estimated based on costs incurred to date plus a reasonable profit margin. If either of the two conditions noted above are not met to recognize revenue over time, revenue is recognized following the transfer of control of such products to the customer, which typically occurs upon shipment or delivery depending on the terms of the underlying arrangement.

The Company recognizes revenue when a contract exists and when, or as, it satisfies a performance obligation by transferring control of a product or service to a customer. Contracts are accounted for when they have approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer.

The Company generally enters into a master services arrangement that establishes the framework under which business will be conducted. These arrangements represent the master terms and conditions of the Company's services that apply to individual orders, but they do not commit the customer to work with, or to continue to work with, the Company nor do they obligate the customer to any specific volume or pricing of purchases. Moreover, these terms can be amended in appropriate situations.

Customer purchase orders are received for specific quantities with predominantly fixed pricing and delivery requirements. Thus, for the majority of our contracts, there is no guarantee of any revenue to the Company until a customer submits a purchase order. As a result, the Company generally considers its arrangement with a customer to be the combination of the master services arrangement and the purchase order. Most of the Company's arrangements with customers create a single performance obligation as the promise to transfer the individual manufactured product or service is capable of being distinct.

The Company’s performance obligations are satisfied over time as work progresses or at a point in time. A performance obligation is satisfied over time if the Company has an enforceable right to payment, including a reasonable profit margin.

16

Determining if an enforceable right to payment includes a reasonable profit margin requires judgment and is assessed on a contract-by-contract basis.

Generally, there are no subjective customer acceptance requirements or further obligations related to goods or services provided; if such requirements or obligations exist, then a sale is recognized at the time when such requirements are completed and such obligations are fulfilled.

The Company does not allow for a general right of return. Net sales include amounts billed to customers for shipping and handling and out-of-pocket expenses. The corresponding shipping and handling costs and out-of-pocket expenses are included in cost of sales. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from net sales.

Contract Costs

For contracts requiring over time revenue recognition, the selection of the method to measure progress toward completion requires judgment and is based on the nature of the products or services to be provided. The Company uses a cost-based input measurement of progress because it best depicts the transfer of assets to the customer, which occurs as costs are incurred during the manufacturing process or as services are rendered. Under the cost-based measure of progress, the extent of progress toward completion is measured based on the costs incurred to date.

There were no other costs to obtain or fulfill customer contracts.

For both the three and six months ended March 30, 2024, approximately 83% of the Company's revenue was recognized as products and services transferred over time. For the three and six months ended April 1, 2023, approximately 80% and 81%, respectively, of the Company's revenue was recognized as products and services transferred over time.

Contract Balances

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, contract assets and deferred revenue on the Company’s accompanying Condensed Consolidated Balance Sheets.

Contract Assets: For performance obligations satisfied at a point in time, billing occurs subsequent to revenue recognition, at which point the customer has been billed and the resulting asset is recorded within accounts receivable. For performance obligations satisfied over time as work progresses, the Company has an unconditional right to payment, which results in the recognition of contract assets. The following table summarizes the activity in the Company's contract assets during the six months ended March 30, 2024 and April 1, 2023 (in thousands):

	Six Months Ended
	March 30, 2024		April 1, 2023
Contract assets, beginning of period	$	142,297	$	138,540
Revenue recognized during the period	1,625,857		1,743,054
Amounts collected or invoiced during the period	(1,636,980)		(1,748,565)
Contract assets, end of period	$	131,174	$	133,029

Deferred Revenue: Deferred revenue is recorded when consideration is received from a customer prior to transferring goods or services to the customer under the terms of the contract, which is included in advanced payments from customers on Condensed Consolidated Balance Sheets. As of March 30, 2024 and September 30, 2023, the balance of advance payments from customers attributable to deferred revenue was $165.3 million and $158.7 million, respectively. The advance payment is not considered a significant financing component because it is used to meet working capital demands that can be higher in the early stages of a contract and to protect the company from the other party failing to adequately complete some or all of its obligations under the

contract. Deferred revenue is recognized into revenue when all revenue recognition criteria are met. For performance obligations satisfied over time, recognition will occur as work progresses; otherwise deferred revenue will be recognized based upon shipping terms.

15.    Restructuring and Non-recurring Charges

Restructuring and non-recurring charges are recorded within restructuring and other charges on the Condensed Consolidated Statements of Comprehensive Income. Restructuring liabilities are primarily recorded within other accrued liabilities on the Condensed Consolidated Balance Sheets.

For the three and six months ended March 30, 2024, the Company incurred restructuring and other charges of $11.0 million, which consisted of severance from the reduction of the Company's workforce as well as closure costs associated with a site in the Company's EMEA region, offset by insurance proceeds received associated with an arbitration decision regarding a contractual matter that occurred in the Company's EMEA region in fiscal 2023.

For the three and six months ended April 1, 2023, the Company did not incur any restructuring and other charges.

The Company recognized a tax benefit of $1.2 million related to restructuring and other charges for the three and six months ended March 30, 2024.

The Company's restructuring accrual activity for the three and six months ended March 30, 2024 is included in the tables below (in thousands):

OVERVIEW

Plexus Corp. and its subsidiaries (together "Plexus," the "Company", "our", or "we") participate in the Electronic Manufacturing Services ("EMS") industry. Since 1979, we have been partnering with companies to create the products that build a better world. We are a global leader with a team of over 20,000 individuals who are dedicated to providing Design and Development, Supply Chain Solutions, New Product Introduction, Manufacturing and Sustaining Services. We specialize in serving customers in industries with highly complex products and demanding regulatory environments. We deliver customer service excellence to leading global companies in the Healthcare/Life Sciences, Industrial and Aerospace/Defense market sectors by providing innovative, comprehensive solutions throughout the product's lifecycle. We provide these innovative solutions to customers in the Americas ("AMER"), Asia-Pacific ("APAC") and Europe, Middle East and Africa ("EMEA") regions.

The following Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") is intended to provide an analysis of both short-term results and future prospects from management’s perspective, including an assessment of the financial condition and results of operations, events and uncertainties that are not indicative of future operations and any other financial or statistical data that we believe will enhance the understanding of our company’s financial condition, cash flows and other changes in financial condition and results of operations

The following information should be read in conjunction with our condensed consolidated financial statements included herein and "Risk Factors" included in Part II, Item 1A included herein as well as Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended September 30, 2023, and our "Safe Harbor" Cautionary Statement included above.

Market Pressures Update

During the first six months of fiscal 2024, we experienced market-driven inventory corrections at our customers and incrementally weaker demand from the Healthcare/Lifesciences and Industrial market sectors creating inefficiencies within our operations. We expect the market-driven inventory corrections at the customers and weaker demand in certain sectors to be a near-term challenge that will lessen later in fiscal 2024. However, if market softness continues for extended periods, this would impact our operating results in future periods.

A global minimum tax has been, or is anticipated to be, implemented in many of the countries in which we operate. We anticipate this will materially and unfavorably impact our existing tax holidays and effective tax rate beginning in our fiscal 2025. We will continue to monitor these developments as each jurisdiction incorporates such changes into tax laws.

We believe our balance sheet is positioned to support the potential future challenges presented by the macro-economic pressures we are facing. As of the second quarter of fiscal 2024, cash and cash equivalents and restricted cash were $265 million, while debt, finance lease obligations and other financing were $438 million. Borrowings under our Credit Facility as of March 30, 2024, were $239 million, leaving $261 million of our revolving commitment of $500 million available for use as well as the ability to expand our revolving commitment to $750 million upon mutual agreement with the bank. Interest expense could increase above current levels due to increased borrowing under our Credit Facility associated with working capital investments along with the impact of rising interest rates. Refer to Note 3, "Debt, Finance Lease and Other Financing Obligations," in Notes to Condensed Consolidated Financial Statements and "Management’s Discussion and Analysis Liquidity and Capital Resources" in Part I, Item 2 for further information.

Net sales. For the three months ended March 30, 2024, net sales decreased $103.9 million, or 9.7%, as compared to the three months ended April 1, 2023. For the six months ended March 30, 2024, net sales decreased $215.2 million, or 9.9%, as compared to the six months ended April 1, 2023.

Net sales are analyzed by management by geographic segment, which reflects our reportable segments, and by market sector. Management measures operational performance and allocates resources on a geographic segment basis. Our global business development strategy is based on our targeted market sectors.

A discussion of net sales by reportable segment is presented below (in millions):

Cost of sales. Cost of sales for the three months ended March 30, 2024 decreased $89.0 million, or 9.2%, as compared to the three months ended April 1, 2023, while cost of sales for the six months ended March 30, 2024 decreased $187.3 million, or 9.6% as compared to the six months ended April 1, 2023. Cost of sales is comprised primarily of material and component costs, labor costs and overhead. For both the three and six months ended March 30, 2024 and April 1, 2023, approximately 89% of the total cost of sales was variable in nature and fluctuated with sales volumes. Approximately 88% of these costs were related to material and component costs.

As compared to the three months ended April 1, 2023, the decrease in cost of sales for the three months ended March 30, 2024 was primarily driven by the decrease in net sales and a positive shift in customer mix. As compared to the six months ended April 1, 2023, the decrease in cost of sales for the six months ended March 30, 2024 was primarily driven by the decrease in net sales and a positive shift in customer mix, partially offset by an increase in fixed costs.

Operating income. Operating income for the three months ended March 30, 2024 decreased $27.4 million, or 48.2%, as compared to the three months ended April 1, 2023. Operating margin of 3.0% for the three months ended March 30, 2024 decreased 230 basis points compared to the three months ended April 1, 2023. The primary driver of the decrease in operating income and operating margin for the three months ended March 30, 2024 was the result of the decrease in gross margin as well as restructuring and other charges of $11.0 million. The restructuring and other charges consisted of severance from the reduction of the Company's workforce as well as closure costs associated with a site in the Company's EMEA region, offset by insurance proceeds received associated with an arbitration decision regarding a contractual matter that occurred in the Company's EMEA region in fiscal 2023.

A discussion of operating income by reportable segment for the indicated fiscal period (in millions):

	Three Months Ended				Six Months Ended
	March 30, 2024		April 1, 2023		March 30, 2024		April 1, 2023
Operating income:
AMER	$	5.0	$	25.8	$	13.7	$	43.2
APAC	67.2		69.7		138.6		148.1
EMEA	5.7		1.8		5.5		1.2
Corporate and other costs	(48.4)		(40.4)		(83.2)		(78.2)
Total operating income	$	29.5	$	56.9	$	74.6	$	114.3

AMER. Operating income decreased $20.8 million for the three months ended March 30, 2024 as compared to the three months ended April 1, 2023 primarily as a result of a decrease in net sales and a negative shift in customer mix, partially offset by a decrease in fixed costs.

During the six months ended March 30, 2024, operating income in the AMER segment decreased $29.5 million as compared to the six months ended April 1, 2023 primarily as a result of a decrease in net sales, partially offset by a positive shift in customer mix and a decrease in fixed costs.

APAC. Operating income decreased $2.5 million for the three months ended March 30, 2024 as compared to the three months ended April 1, 2023 primarily as a result of a decrease in net sales, partially offset by a positive shift in customer mix.

During the six months ended March 30, 2024, operating income in the APAC segment decreased $9.5 million as compared to the six months ended April 1, 2023 primarily as a result of a decrease in net sales, partially offset by a positive shift in customer mix and a decrease in S&A.

EMEA. Operating income increased $3.9 million for the three months ended March 30, 2024 as compared to the three months ended April 1, 2023 primarily as a result of an increase in net sales, partially offset by increased fixed costs.

During the six months ended March 30, 2024, operating income in the EMEA segment increased $4.3 million as compared to the six months ended April 1, 2023 primarily as a result of an increase in net sales, partially offset by increased fixed costs.

Other expense. Other expense for the three months ended March 30, 2024 increased $1.4 million as compared to the three months ended April 1, 2023. The increase in other expense for the three months ended March 30, 2024 was primarily driven by a decrease in other miscellaneous income of $1.5 million.

Other expense for the six months ended March 30, 2024 increased $3.8 million as compared to the six months ended April 1, 2023. The increase in other expense for the six months ended March 30, 2024 was primarily driven by a decrease in other miscellaneous income of $2.5 million, an increase in interest expense of $0.7 million due to a higher average interest rate and an increase in factoring fees of $0.5 million.

Income taxes. Income tax expense for the three and six months ended March 30, 2024 was $2.7 million and $8.4 million, respectively, compared to $7.0 million and $14.2 million for the three and six months ended April 1, 2023. The decrease is primarily due to a decrease in pre-tax book income.

Our annual effective tax rate varies from the U.S. statutory rate of 21.0% primarily due to the geographic distribution of worldwide earnings as well as a tax holiday granted to a subsidiary located in the APAC segment where we derive a significant portion of our earnings. Our effective tax rate may also be impacted by disputes with taxing authorities, tax planning activities, adjustments to uncertain tax positions and changes in valuation allowances.

The annual effective tax rate for fiscal 2024 is expected to be approximately 15.0% to 17.0% assuming no changes to tax laws.

Net Income. Net income for the three months ended March 30, 2024 decreased $24.6 million, or 60.3%, from the three months ended April 1, 2023 to $16.2 million. Net income decreased primarily as a result of the decrease in operating income and the increase in other expense, partially offset by the decrease in tax expense as previously discussed.

Net income for the six months ended March 30, 2024 decreased $37.5 million, or 45.2%, from the six months ended April 1, 2023 to $45.5 million. Net income decreased primarily as a result of the decrease in operating income and the increase in other expense, partially offset by the decrease in tax expense as previously discussed.

25

Diluted earnings per share. Diluted earnings per share decreased to $0.58 for the three months ended March 30, 2024 from $1.45 for the three months ended April 1, 2023 primarily as a result of decreased net income due to the factors discussed above, partially offset by a reduction in diluted shares outstanding.

Diluted earnings per share decreased to $1.62 for the six months ended March 30, 2024 from $2.94 for the six months ended April 1, 2023 primarily as a result of decreased net income due to the factors discussed above, partially offset by a reduction in diluted shares outstanding.

Return on Invested Capital ("ROIC") and economic return. We use a financial model that is aligned with our business strategy and includes an ROIC goal of 15% which would exceed our weighted average cost of capital ("WACC") by more than 500 basis points and represent positive economic return. Economic return is the amount our ROIC exceeds our WACC.

Non-GAAP financial measures, including ROIC and economic return, are used for internal management goals and decision making because such measures provide management and investors additional insight into financial performance. In particular, we provide ROIC and economic return because we believe they offer insight into the metrics that are driving management decisions. We view ROIC and economic return as important measures in evaluating the efficiency and effectiveness of our long-term capital investments. We also use ROIC as a performance criteria in determining certain elements of compensation as well as economic return performance.

We define ROIC as tax-effected operating income before restructuring and other charges divided by average invested capital over a rolling three-quarter period for the second period. Invested capital is defined as equity plus debt and operating lease liabilities, less cash and cash equivalents. Other companies may not define or calculate ROIC in the same way. ROIC and other non-GAAP financial measures should be considered in addition to, not as a substitute for, measures of our financial performance prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP").

We review our internal calculation of WACC annually. Our WACC is 8.2% for fiscal 2024 and 9.0% for fiscal 2023. By exercising discipline to generate ROIC in excess of our WACC, our goal is to create value for our shareholders. For the six months ended March 30, 2024, ROIC of 9.9% reflects an economic return of 1.7%, based on our WACC of 8.2%, and for the six months ended April 1, 2023, ROIC of 13.8% reflects an economic return of 4.8%, based on our weighted average cost of capital of 9.0%.

For a reconciliation of ROIC, economic return and adjusted operating income (tax-effected) to our financial statements that were prepared using U.S. GAAP, see Exhibit 99.1 to this quarterly report on Form 10-Q, which exhibit is incorporated herein by reference.

Refer to the table below, which includes the calculation of ROIC and economic return for the indicated fiscal period (dollars in millions):

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents and restricted cash were $265.1 million as of March 30, 2024 as compared to $256.7 million as of September 30, 2023.

As of March 30, 2024, 93% of our cash and cash equivalents balance was held outside of the U.S. by our foreign subsidiaries. Currently, we believe that our cash balance, together with cash available under our Credit Facility, will be sufficient to meet our liquidity needs and potential share repurchases for the next twelve months and the foreseeable future.

Our future cash flows from operating activities will be reduced by $31.4 million due to cash payments for U.S. federal taxes on the deemed repatriation of undistributed foreign earnings that are payable over an eight year period that began in fiscal 2019 with the first payment. The table below provides the expected timing of these future cash outflows, in accordance with the following installment schedule for the remaining two years (in millions):

2025	$	14.2
2026	17.2
Total	$	31.4

Cash Flows. The following table provides a summary of cash flows (in millions):

	Six Months Ended
	March 30, 2024		April 1, 2023
Cash flows provided by operating activities	$	84.8	$	57.2
Cash flows used in investing activities	(51.3)		(47.6)
Cash flows used in financing activities	(25.6)		(18.4)
Effect of exchange rate changes on cash and cash equivalents	0.5		3.8
Net increase (decrease) in cash and cash equivalents and restricted cash	$	8.4	$	(5.1)

Operating Activities. Cash flows provided by operating activities were $84.8 million for the six months ended March 30, 2024, as compared to cash flows provided by operating activities of $57.2 million for the six months ended April 1, 2023. The increase was primarily due to cash flow improvements (reductions) of:

•$(37.5) million decrease in net income.

•$81.8 million in inventory cash flows driven by a decrease in inventory in the six months ended March 30, 2024 compared to an increase in inventory in the six months ended April 1, 2023 due to inventory reduction efforts and fewer program ramps requiring upfront inventory procurement.

•$81.4 million in accounts payables cash flows primarily driven by the timing of materials procurement and payments to suppliers.

•$(66.3) million in accounts receivable cash flows driven by timing of shipments, mix of customer payment terms, partially offset by increased factoring of receivables.

•$(22.5) million in advanced payments from customers cash flows driven by a decrease in advanced payments in the six months ended March 30, 2024 compared to an increase in advanced payments in the six months ended April 1, 2023.

•$(16.5) million in other current and non-current asset cash flows driven by an increase in tax prepayments related to timing of payments and a larger increase in prepayments to suppliers in the six months ended March 30, 2024 compared to the six months ended April 1, 2023.

27

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

	Three Months Ended
	March 30, 2024	April 1, 2023
Days in accounts receivable	61	56
Days in contract assets	12	11
Days in inventory	158	156
Days in accounts payable	(65)	(69)
Days in advanced payments (1)	(75)	(72)
Annualized cash cycle	91	82
(1) Includes a reclassification in the presentation of advanced payments from customers reflected in prior period amounts. As of April 1, 2023, the impact of this reclassification was an increase in the Company's days in advanced payments and a reduction in annualized cash cycle by 22 days.

We calculate days in accounts receivable and contract assets as each balance sheet item for the respective quarter divided by annualized sales for the respective quarter by day. We calculate days in inventory, accounts payable and advanced payments as each balance sheet line item for the respective quarter divided by annualized cost of sales for the respective quarter by day. We calculate annualized cash cycle as the sum of days in accounts receivable, days in contract assets and days in inventory, less days in accounts payable and days in advanced payments.

As of March 30, 2024, annualized cash cycle days increased nine days compared to April 1, 2023 due to the following:

Days in accounts receivable for the three months ended March 30, 2024 increased five days compared to the three months ended April 1, 2023. The increase is attributable to the timing of customer shipments and payments, the mix of customer payment terms, as well as decreased factoring of receivables.

Days in contract assets for the three months ended March 30, 2024 increased one day compared to the three months ended April 1, 2023. The increase is primarily attributable to a decrease in advanced payments from customers with arrangements requiring revenue to be recognized over time as products are produced.

Days in inventory for the three months ended March 30, 2024 increased two days compared to the three months ended April 1, 2023. The increase is primarily due to lower sales in the three months ended March 30, 2024 compared to the prior year, partially offset by lower inventory.

Days in accounts payable for the three months ended March 30, 2024 decreased four days compared to the three months ended April 1, 2023. The decrease is primarily attributable to timing of materials procurement and payments to suppliers.

Days in advanced payments for the three months ended March 30, 2024 increased three days compared to the three months ended April 1, 2023. The increase was primarily attributable to lower sales in the three months ended March 30, 2024 compared to the prior year, partially offset by a decrease in advanced payments received from customers in line with lower inventory balances.

Free Cash Flow. We define free cash flow ("FCF"), a non-GAAP financial measure, as cash flow generated or used in operations less capital expenditures. FCF was $33.3 million for the six months ended March 30, 2024 compared to $7.7 million for the six months ended April 1, 2023, an improvement of $25.6 million. The improvement in FCF was primarily due to lower working capital investments in inventory to support our customers and favorable accounts payable activity due to timing of payments.

Non-GAAP financial measures, including FCF, are used for internal management assessments because such measures provide additional insight to investors 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 can allow us to pursue opportunities that enhance shareholder value. FCF is a non-GAAP financial measure that should be considered in addition to, not as a substitute for, measures of our financial performance prepared in accordance with GAAP.

28

A reconciliation of FCF to our financial statements that were prepared using GAAP as follows (in millions):

	Six Months Ended
	March 30, 2024		April 1, 2023
Cash flows provided by operating activities	$	84.8	$	57.2
Payments for property, plant and equipment	(51.5)		(49.5)
Free cash flow	$	33.3	$	7.7

Investing Activities. Cash flows used in investing activities were $51.3 million for the six months ended March 30, 2024 compared to $47.6 million for the six months ended April 1, 2023. The increase in cash used in investing activities was due to a $2.0 million increase in capital expenditures.

We estimate capital expenditures for fiscal 2024 will be approximately $100.0 million to $120.0 million to support new program ramps and replace older equipment.

Financing Activities. Cash flows used in financing activities were $25.6 million for the six months ended March 30, 2024 compared to cash flows used in financing activities of $18.4 million for the six months ended April 1, 2023. The increase was primarily attributable to net borrowings on the credit facility for the six months ended March 30, 2024 of $6.0 million compared to net borrowings on the credit facility for the six months ended April 1, 2023 of $21.0 million, partially offset by a $6.3 million reduction in repurchases of our common stock.

On August 18, 2022, the Board of Directors approved a share repurchase program under which we are authorized to repurchase up to $50.0 million of its common stock (the "2023 Program"). The 2023 Program was completed in February 2024. During the three and six months ended March 30, 2024 we repurchased 59,277 shares under this program for $5.7 million at an average price of $95.59 per share. During the three months ended April 1, 2023, we repurchased 125,639 shares under this program for $12.4 million at an average price of $98.75 per share. During the six months ended April 1, 2023, we repurchased 241,362 shares under this program for $23.9 million at an average price of $98.93 per share.

On January 16, 2024, we announced an additional $50.0 million in share repurchase authority (the "2024 Program") that authorizes us to repurchase our common stock. The 2024 Program became effective upon completion of the 2023 Program, which occurred in February 2024, and has no expiration. During the three and six months ended March 30, 2024, we repurchased 126,850 shares under this program for $11.9 million at an average price of $93.83 per share. As of March 30, 2024, $38.1 million of the 2024 Program remained available to repurchase shares.

All shares repurchased under the aforementioned programs were recorded as treasury stock.

We have Master Accounts Receivable Purchase Agreements with MUFG Bank, New York Branch (formerly known as The Bank of Tokyo-Mitsubishi UFJ, Ltd.) (the "MUFG RPA"), HSBC Bank (China) Company Limited, Xiamen branch (the "HSBC RPA") and other unaffiliated financial institutions, under which we may elect to sell receivables, at a discount. These facilities are uncommitted facilities. The maximum facility amount under the MUFG RPA as of March 30, 2024 is $340.0 million. The maximum facility amount under the HSBC RPA as of March 30, 2024 is $70.0 million. The MUFG RPA will be automatically extended each year unless any party gives no less than 10 days prior notice that the agreement should not be extended. The terms of the HSBC RPA are generally consistent with the terms of the MUFG RPA previously discussed.

We sold $213.8 million and $225.7 million of trade accounts receivable under these programs during the three months ended March 30, 2024 and April 1, 2023, respectively, in exchange for cash proceeds of $211.1 million and $222.9 million, respectively. We sold $437.4 million and $411.3 million of trade accounts receivable under these programs during the six months ended March 30, 2024 and April 1, 2023, respectively, in exchange for cash proceeds of $432.1 million and $406.5 million, respectively. As of March 30, 2024 and September 30, 2023, $217.8 million and $220.5 million, respectively, of accounts receivables sold under trade accounts receivable programs and subject to servicing by us remained outstanding and had not yet been collected by MUFG Bank or HSBC Bank.

In all cases, the sale discount was recorded within "Miscellaneous, net" in the Condensed Consolidated Statements of Comprehensive Income in the period of the sale. For further information regarding the receivable sale programs, see Note 13, "Trade Accounts Receivable Sale Programs," in Notes to Condensed Consolidated Financial Statements.

Based on current expectations, we believe that our projected cash flows provided by operations, available cash and cash equivalents, potential borrowings under the Credit Facility and our leasing capabilities should be sufficient to meet our working capital and fixed capital requirements, as well as execution upon our share repurchase authorizations as management deems

29

appropriate, for the next twelve months. We believe our balance sheet is positioned to support the potential future challenges presented by macroeconomic factors including increased working capital requirements associated with longer lead-times for components, increased component and labor costs, and operating inefficiencies due to supply chain constraints. As of the end of the second quarter of fiscal 2024, cash and cash equivalents and restricted cash were $265 million, while debt, finance lease and other financing obligations were $438 million. If our future financing needs increase, then 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, we cannot be assured that we will be able to make any such arrangements on acceptable terms or at all.

DISCLOSURE ABOUT CRITICAL ACCOUNTING ESTIMATES

Our critical accounting policies are disclosed in our 2023 Annual Report on Form 10-K. During the second quarter of fiscal 2024, there were no material changes.

NEW ACCOUNTING PRONOUNCEMENTS

See Note 1, "Recently Adopted Accounting Pronouncements" and "Recently Issued Accounting Pronouncements Not Yet Adopted," in Notes to Condensed Consolidated Financial Statements regarding recent accounting pronouncements. 

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There were no material changes in our exposure to market risk from changes in foreign exchange and interest rates from those disclosed in our 2023 Annual Report on Form 10-K.

Foreign Currency Risk

Our international operations create potential foreign exchange risk. 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. We cannot predict changes in currency rates, nor the degree to which we will be able to manage the impacts of currency exchange rate changes. Such changes could have a material effect on our business, results of operations and financial condition.

Our percentages of transactions denominated in currencies other than the U.S. dollar for the indicated periods were as follows:

	Three Months Ended
	March 30, 2024	April 1, 2023
Net Sales	13%	9%
Total Costs	18%	21%

We have 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 our overall currency exposure, as of March 30, 2024, a 10.0% change in the value of the U.S. dollar relative to our other transactional currencies would not have a material effect on our financial position, results of operations, or cash flows.

Interest Rate Risk

We have financial instruments, including cash equivalents and debt, which are sensitive to changes in interest rates. The primary objective of our investment activities is to preserve principal, while maximizing yields without significantly increasing market risk. To achieve this, we limit the amount of principal exposure to any one issuer.

As of March 30, 2024, we were exposed to interest rate risk associated with our Credit Facility. Borrowings under the Credit Facility bear interest, at the Company's option, at (a)(1) for borrowings denominated in U.S. dollars, the Term Secured Overnight Financing Rate ("SOFR"), (2) for borrowings denominated in pounds sterling, the Daily Simple Risk-Free Rate, plus, in each case of (a)(1) and (2), 10 basis points, (b) for borrowings denominated in euros, the EURIBOR Rate plus a statutory reserve rate, or (c) an Alternate Base Rate equal to the highest of (i) 100 basis points per annum, (ii) the prime rate last quoted

30

by The Wall Street Journal (or, if not quoted, as otherwise provided in the Credit Facility), (iii) the greater of the federal funds effective rate and the overnight bank funding rate in effect on such day plus, in each case, 50 basis points per annum (or, if neither are available, as otherwise provided in the Credit Facility), and (iv) Term SOFR for a one month interest period on such day plus 110 basis points, plus, in each case of (a), (b), and (c), an applicable interest rate margin based on the Company's then current consolidated total indebtedness (minus certain unrestricted cash and cash equivalents in an amount not to exceed $100 million) to consolidated EBITDA. As of March 30, 2024, the borrowing rate under the Credit Facility was SOFR plus 1.10%. Borrowings under the 2018 NPA are based on a fixed interest rate, thus mitigating much of our interest rate risk. We were also exposed to interest rate risk on our accounts receivables sales programs. The Master Accounts Receivable Purchase Agreements with MUFG Bank, New York Branch (the "MUFG RPA") is subject to an applicable cost of funds based on an applicable margin defined in the agreement with respect to receivables owed by each approved obligor and the applicable SOFR for a period equal to the discount period applicable to such receivable determined as of two business days prior to the applicable purchase date of such receivable with respect to the currency the receivable is denominated in. Other trade receivable sales programs are subject to similar terms. Based on our overall interest rate exposure, as of March 30, 2024, a 10.0% change in interest rates would not have a material effect on our financial position, results of operations, or cash flows.

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 Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO") 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. Based on such evaluation, the CEO and CFO have concluded that, as of the Evaluation Date, the Company’s disclosure controls and procedures are effective, at the reasonable assurance level, (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 CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

During the second quarter of fiscal 2024, there have been no changes in 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.

The 2023 Program was completed in February 2024. On January 16, 2024, the Company announced an additional $50.0 million in share repurchase authority (the "2024 Program") that authorizes us to repurchase its common stock. The 2024 Program commenced upon completion of the 2023 Program.

ITEM 5.    OTHER INFORMATION

On January 31, 2024, Patrick Jermain, the Company's Executive Vice President and Chief Financial Officer, adopted a Rule 10b5-1 trading arrangement that is intended to satisfy the affirmative defense of Rule 10b5-1(c) for the sale of up to 13,499 shares of the Company's common stock through April 30, 2025.

SECTION 906 OF THE SARBANES-OXLEY ACT OF 2002

In connection with the Quarterly Report of Plexus Corp.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

Basis of Presentation:

The accompanying Condensed Consolidated Financial Statements included herein have been prepared by Plexus Corp. and its subsidiaries (together “Plexus” or the “Company”) without audit and pursuant to the rules and regulations of the United States (“U.S.”) Securities and Exchange Commission (“SEC”). The accompanying Condensed Consolidated Financial Statements reflect all adjustments, which include normal recurring adjustments necessary for the fair statement of the condensed consolidated financial position of the Company as of March 30, 2024 and September 30, 2023, the results of operations and shareholders' equity for the three and six months ended March 30, 2024 and April 1, 2023, and the cash flows for the same six month periods.

The Company’s fiscal year ends on the Saturday closest to September 30. The Company uses a “4-4-5” weekly accounting system for the interim periods in each quarter. Each quarter, therefore, ends on a Saturday at the end of the 4-4-5 period. Periodically, an additional week must be added to the fiscal year to re-align with the Saturday closest to September 30. All fiscal quarters presented herein included 13 weeks.

Certain information and footnote disclosures, normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"), 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 2023 Annual Report on Form 10-K.

The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in the Condensed Consolidated Financial Statements and notes thereto. The Company has considered information available as of the date of issuance of these financial statements and, other than the information disclosed in Note 16, "Subsequent Event", is not aware of any specific events or circumstances that would require an update to its estimates or judgments or a revision of the carrying value of its assets or liabilities. These estimates may change as new events occur and additional information becomes available. Actual results could differ materially from these estimates.

Reclassification:

Certain prior year amounts in the consolidated financial statements and notes thereto have been reclassified related to advanced payments from customers to conform to the current year's presentation.

Recently Adopted Accounting Pronouncements:

In September 2022, the FASB issued ASU 2022-04 Supplier Finance Programs (Subtopic 405-50), which requires enhanced disclosures about supplier finance programs. The Company adopted this guidance during the first quarter of fiscal 2024 with no material impact to the Company's Consolidated Financial Statements; however, the impact of the new standard on future periods will depend on the facts and circumstances of future transactions.

Recently Issued Accounting Pronouncements Not Yet Adopted:

In March 2024, the SEC adopted final rules to require registrants to disclose certain climate-related information in registration statements and annual reports. The SEC stayed its climate disclosure rules to facilitate the orderly judicial resolution of pending legal challenges. We are currently evaluating the impacts that the SEC's rule will have on our financial statement disclosures.

In November 2023, the FASB issued ASU 2023-07 Segment Reporting (Topic 280), which requires enhanced disclosures for segment reporting. The guidance is effective for the Company beginning in the first quarter of fiscal 2025. We are currently evaluating the impact that the updated standard will have on our financial statement disclosures.

In December 2023, the FASB issued ASU 2023-09 Income Taxes (Topic 740), which requires enhanced disclosures for income taxes. The guidance is effective for the Company beginning in the first quarter of fiscal 2026. Early adoption is permitted. We are currently evaluating the impact that the updated standard will have on our financial statement disclosures.

The Company does not believe that any other recently issued accounting standards will have a material impact on its Consolidated Financial Statements or apply to its operations.

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. The Company uses derivatives to manage the variability of foreign currency obligations. The Company has cash flow hedges related to forecasted foreign currency obligations, in addition to non-designated hedges to manage foreign currency exposures associated with certain foreign currency denominated assets and liabilities. The Company does not enter into derivatives for speculative purposes.

The Company designates some foreign currency exchange contracts as cash flow hedges of forecasted foreign currency expenses. Changes in the fair value of the derivatives that qualify as cash flow hedges are recorded in "Accumulated other comprehensive loss" in the accompanying Condensed Consolidated Balance Sheets until earnings are affected by the variability of the cash flows. In the next twelve months, the Company estimates that $1.8 million of unrealized gains, net of tax, related to cash flow hedges will be reclassified from other comprehensive income into earnings. Changes in the fair value of the non-designated derivatives related to recognized foreign currency denominated assets and liabilities are recorded in "Miscellaneous, net" in the accompanying Condensed Consolidated Statements of Comprehensive Income.

The Company enters into forward currency exchange contracts for its operations in certain jurisdictions in the AMER and APAC segments on a rolling basis. The Company had cash flow hedges outstanding with a notional value of $275.0 million as of March 30, 2024, and a notional value of $215.4 million as of September 30, 2023. These forward currency contracts fix the exchange rates for the settlement of future foreign currency obligations that have yet to be realized. The total fair value of the forward currency exchange contracts was a $1.8 million asset as of March 30, 2024 and a $5.0 million liability as of September 30, 2023.

The Company had additional forward currency exchange contracts outstanding as of March 30, 2024, with a notional value of $220.7 million; there were $145.5 million of such contracts outstanding as of September 30, 2023. The Company did not designate these derivative instruments as hedging instruments. The net settlement amount (fair value) related to these contracts is recorded on the Condensed Consolidated Balance Sheets as either a current or long-term asset or liability, depending on the term, and as an element of "Miscellaneous, net" in the Condensed Consolidated Statements of Comprehensive Income. The total fair value of these derivatives was a $0.3 million liability as of March 30, 2024 and a $1.3 million liability as of September 30, 2023.

Fair Value Measurements:

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 Company uses quoted market prices when available or discounted cash flows to calculate fair value. 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.

The following table lists the fair values of the Company’s derivatives as of March 30, 2024 and September 30, 2023 by input level:

Fair Value Measurements Using Input Levels Asset / (Liability) (in thousands)
Fiscal period ended March 30, 2024	Level 1		Level 2		Level 3		Total

Fiscal period ended September 30, 2023
Derivatives
Foreign currency forward contracts	$	—	$	(6,312)	$	—	$	(6,312)

The fair value of 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. Inputs in the fair value of the foreign currency forward contracts include prevailing forward and spot prices for currency.

Income Taxes

Income Taxes

Income tax expense for the three and six months ended March 30, 2024 was $2.7 million and $8.4 million compared to $7.0 million and $14.2 million for the three and six months ended April 1, 2023.

The effective tax rates for the three and six months ended March 30, 2024 were 14.4% and 15.5%, respectively, compared to the effective tax rate of 14.6% for the three and six months ended April 1, 2023. The increase for the six months ended March 30, 2024 compared to the six months ended April 1, 2023 is primarily due to a change in the geographic distribution of pre-tax book income.

The amount of unrecognized tax benefits recorded for uncertain tax positions increased by $1.0 million for the three months ended March 30, 2024. The Company recognizes accrued interest and penalties on uncertain tax positions as a component of income tax expense. The amount of interest and penalties recorded for the three and six months ended March 30, 2024 was not material.

One or more uncertain tax positions may be settled within the next 12 months. Settlement of these matters is not expected to have a material effect on the Company's consolidated results of operations, financial position and cash flows. The Company is not currently under examination by taxing authorities in the U.S. or any foreign jurisdiction.

The Company maintains valuation allowances when it is more likely than not that all or a portion of a net deferred tax asset will not be realized. During the three months ended March 30, 2024, the Company continued to record a full valuation allowance against its net deferred tax assets in certain jurisdictions within the EMEA and APAC segments and a partial valuation against its net deferred tax assets in certain jurisdictions within the AMER segment, as it was more likely than not that these assets would not be fully realized based primarily on historical performance. The Company will continue to provide a valuation allowance against its net deferred tax assets in each of the applicable jurisdictions going forward until it determines it is more likely than not that the deferred tax assets will be realized.

Share-Based Compensation

At the 2024 Annual Meeting of Shareholders on February 14, 2024, the Company's shareholders approved the Plexus Corp. 2024 Omnibus Incentive Plan (the "2024 Plan"). The 2024 Plan is a stock and cash-based incentive plan, and includes provisions by which the Company may grant executive officers, employees and directors stock options, stock appreciation rights ("SARs"), restricted stock (including restricted stock units ("RSUs")), performance stock awards (including performance stock units ("PSUs")), other stock awards and cash incentive awards. Similar awards were offered under its predecessor, the Plexus Corp. 2016 Omnibus Incentive Plan (the "2016 Plan"), which is no longer being used for grants; however, outstanding awards granted under the 2016 Plan and its predecessor continue until vesting, exercise, forfeiture or expiration.

The Company recognized $7.1 million and $12.4 million of compensation expense associated with share-based awards for the three and six months ended March 30, 2024, respectively, and $5.9 million and $11.7 million for the three and six months ended April 1, 2023, respectively.

Segment Reporting [Abstract]

Reportable Segments

Reportable Segments

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 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 the segments are attributed to the region in which the product is manufactured or the 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. A segment’s operating income includes its net sales less cost of sales and selling and administrative expenses, but excludes corporate and other expenses. Corporate and other expenses primarily represent corporate selling and administrative expenses, and restructuring and other charges, 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 segments are the same as for the Company taken as a whole.

Information about the Company’s three reportable segments for the three and six months ended March 30, 2024 and April 1, 2023 is as follows (in thousands):

Guarantees [Abstract]

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. 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 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 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 the six months ended March 30, 2024 and April 1, 2023 (in thousands):

Receivables [Abstract]

Trade Accounts Receivable Sale Programs

Trade Accounts Receivable Sale Programs

The Company has Master Accounts Receivable Purchase Agreements with MUFG Bank, New York Branch (formerly known as The Bank of Tokyo-Mitsubishi UFJ, Ltd.) (the "MUFG RPA"), HSBC Bank (China) Company Limited, Xiamen branch (the "HSBC RPA") and other unaffiliated financial institutions, under which the Company may elect to sell receivables at a discount. All facilities are uncommitted facilities. The maximum facility amount under the MUFG RPA is $340.0 million. The maximum facility amount under the HSBC RPA is $70.0 million. The MUFG RPA will be automatically extended each year unless any party gives no less than 10 days prior notice that the agreement should not be extended. The terms of the HSBC RPA are generally consistent with the terms of the MUFG RPA.

Transfers of receivables under the programs are accounted for as sales and, accordingly, receivables sold under the programs are excluded from accounts receivable on the Condensed Consolidated Balance Sheets and are reflected as cash provided by operating activities on the Condensed Consolidated Statements of Cash Flows. Proceeds from the transfer reflect the face value of the receivables less a discount. The sale discount is recorded within "Miscellaneous, net" in the Condensed Consolidated Statements of Comprehensive Income in the period of the sale. The Company continues servicing receivables sold and performing all accounts receivable administrative functions, in exchange receives a servicing fee, under both the MUFG RPA and HSBC RPA. Servicing fees related to trade accounts receivable programs recognized during the three and six months ended March 30, 2024 and April 1, 2023 were not material.

The Company sold $213.8 million and $225.7 million of trade accounts receivable under these programs, or their predecessors, during the three months ended March 30, 2024 and April 1, 2023, respectively, in exchange for cash proceeds of $211.1 million and $222.9 million, respectively.

The Company sold $437.4 million and $411.3 million of trade accounts receivable under these programs, or their predecessors, during the six months ended March 30, 2024 and April 1, 2023, respectively, in exchange for cash proceeds of $432.1 million and $406.5 million, respectively.

As of March 30, 2024 and September 30, 2023, $217.8 million and $220.5 million, respectively, of accounts receivables sold under trade accounts receivable programs and subject to servicing by the Company remained outstanding and had not yet been collected by MUFG Bank or HSBC Bank.

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customers

Revenue from Contracts with Customers

Revenue is recognized over time for arrangements with customers for which: (i) the Company's performance does not create an asset with an alternative use to the Company, and (ii) the Company has an enforceable right to payment, including reasonable profit margin, for performance completed to date. Revenue recognized over time is estimated based on costs incurred to date plus a reasonable profit margin. If either of the two conditions noted above are not met to recognize revenue over time, revenue is recognized following the transfer of control of such products to the customer, which typically occurs upon shipment or delivery depending on the terms of the underlying arrangement.

The Company recognizes revenue when a contract exists and when, or as, it satisfies a performance obligation by transferring control of a product or service to a customer. Contracts are accounted for when they have approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer.

The Company generally enters into a master services arrangement that establishes the framework under which business will be conducted. These arrangements represent the master terms and conditions of the Company's services that apply to individual orders, but they do not commit the customer to work with, or to continue to work with, the Company nor do they obligate the customer to any specific volume or pricing of purchases. Moreover, these terms can be amended in appropriate situations.

Customer purchase orders are received for specific quantities with predominantly fixed pricing and delivery requirements. Thus, for the majority of our contracts, there is no guarantee of any revenue to the Company until a customer submits a purchase order. As a result, the Company generally considers its arrangement with a customer to be the combination of the master services arrangement and the purchase order. Most of the Company's arrangements with customers create a single performance obligation as the promise to transfer the individual manufactured product or service is capable of being distinct.

The Company’s performance obligations are satisfied over time as work progresses or at a point in time. A performance obligation is satisfied over time if the Company has an enforceable right to payment, including a reasonable profit margin.

Determining if an enforceable right to payment includes a reasonable profit margin requires judgment and is assessed on a contract-by-contract basis.

Generally, there are no subjective customer acceptance requirements or further obligations related to goods or services provided; if such requirements or obligations exist, then a sale is recognized at the time when such requirements are completed and such obligations are fulfilled.

The Company does not allow for a general right of return. Net sales include amounts billed to customers for shipping and handling and out-of-pocket expenses. The corresponding shipping and handling costs and out-of-pocket expenses are included in cost of sales. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from net sales.

Contract Costs

For contracts requiring over time revenue recognition, the selection of the method to measure progress toward completion requires judgment and is based on the nature of the products or services to be provided. The Company uses a cost-based input measurement of progress because it best depicts the transfer of assets to the customer, which occurs as costs are incurred during the manufacturing process or as services are rendered. Under the cost-based measure of progress, the extent of progress toward completion is measured based on the costs incurred to date.

There were no other costs to obtain or fulfill customer contracts.

For both the three and six months ended March 30, 2024, approximately 83% of the Company's revenue was recognized as products and services transferred over time. For the three and six months ended April 1, 2023, approximately 80% and 81%, respectively, of the Company's revenue was recognized as products and services transferred over time.

Contract Balances

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, contract assets and deferred revenue on the Company’s accompanying Condensed Consolidated Balance Sheets.

Contract Assets: For performance obligations satisfied at a point in time, billing occurs subsequent to revenue recognition, at which point the customer has been billed and the resulting asset is recorded within accounts receivable. For performance obligations satisfied over time as work progresses, the Company has an unconditional right to payment, which results in the recognition of contract assets. The following table summarizes the activity in the Company's contract assets during the six months ended March 30, 2024 and April 1, 2023 (in thousands):

	Six Months Ended
	March 30, 2024		April 1, 2023
Contract assets, beginning of period	$	142,297	$	138,540
Revenue recognized during the period	1,625,857		1,743,054
Amounts collected or invoiced during the period	(1,636,980)		(1,748,565)
Contract assets, end of period	$	131,174	$	133,029

Deferred Revenue: Deferred revenue is recorded when consideration is received from a customer prior to transferring goods or services to the customer under the terms of the contract, which is included in advanced payments from customers on Condensed Consolidated Balance Sheets. As of March 30, 2024 and September 30, 2023, the balance of advance payments from customers attributable to deferred revenue was $165.3 million and $158.7 million, respectively. The advance payment is not considered a significant financing component because it is used to meet working capital demands that can be higher in the early stages of a contract and to protect the company from the other party failing to adequately complete some or all of its obligations under the

contract. Deferred revenue is recognized into revenue when all revenue recognition criteria are met. For performance obligations satisfied over time, recognition will occur as work progresses; otherwise deferred revenue will be recognized based upon shipping terms.

Restructuring and Non-recurring Charges

Restructuring and Non-recurring Charges

Restructuring and non-recurring charges are recorded within restructuring and other charges on the Condensed Consolidated Statements of Comprehensive Income. Restructuring liabilities are primarily recorded within other accrued liabilities on the Condensed Consolidated Balance Sheets.

For the three and six months ended March 30, 2024, the Company incurred restructuring and other charges of $11.0 million, which consisted of severance from the reduction of the Company's workforce as well as closure costs associated with a site in the Company's EMEA region, offset by insurance proceeds received associated with an arbitration decision regarding a contractual matter that occurred in the Company's EMEA region in fiscal 2023.

For the three and six months ended April 1, 2023, the Company did not incur any restructuring and other charges.

The Company recognized a tax benefit of $1.2 million related to restructuring and other charges for the three and six months ended March 30, 2024.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation:

The accompanying Condensed Consolidated Financial Statements included herein have been prepared by Plexus Corp. and its subsidiaries (together “Plexus” or the “Company”) without audit and pursuant to the rules and regulations of the United States (“U.S.”) Securities and Exchange Commission (“SEC”). The accompanying Condensed Consolidated Financial Statements reflect all adjustments, which include normal recurring adjustments necessary for the fair statement of the condensed consolidated financial position of the Company as of March 30, 2024 and September 30, 2023, the results of operations and shareholders' equity for the three and six months ended March 30, 2024 and April 1, 2023, and the cash flows for the same six month periods.

The Company’s fiscal year ends on the Saturday closest to September 30. The Company uses a “4-4-5” weekly accounting system for the interim periods in each quarter. Each quarter, therefore, ends on a Saturday at the end of the 4-4-5 period. Periodically, an additional week must be added to the fiscal year to re-align with the Saturday closest to September 30. All fiscal quarters presented herein included 13 weeks.

Certain information and footnote disclosures, normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"), 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 2023 Annual Report on Form 10-K.

The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in the Condensed Consolidated Financial Statements and notes thereto. The Company has considered information available as of the date of issuance of these financial statements and, other than the information disclosed in Note 16, "Subsequent Event", is not aware of any specific events or circumstances that would require an update to its estimates or judgments or a revision of the carrying value of its assets or liabilities. These estimates may change as new events occur and additional information becomes available. Actual results could differ materially from these estimates.

Reclassification

Reclassification:

Certain prior year amounts in the consolidated financial statements and notes thereto have been reclassified related to advanced payments from customers to conform to the current year's presentation.

Recently Adopted and Recently Issued Accounting Pronouncements Not Yet Adopted

Recently Adopted Accounting Pronouncements:

In September 2022, the FASB issued ASU 2022-04 Supplier Finance Programs (Subtopic 405-50), which requires enhanced disclosures about supplier finance programs. The Company adopted this guidance during the first quarter of fiscal 2024 with no material impact to the Company's Consolidated Financial Statements; however, the impact of the new standard on future periods will depend on the facts and circumstances of future transactions.

Recently Issued Accounting Pronouncements Not Yet Adopted:

In March 2024, the SEC adopted final rules to require registrants to disclose certain climate-related information in registration statements and annual reports. The SEC stayed its climate disclosure rules to facilitate the orderly judicial resolution of pending legal challenges. We are currently evaluating the impacts that the SEC's rule will have on our financial statement disclosures.

In November 2023, the FASB issued ASU 2023-07 Segment Reporting (Topic 280), which requires enhanced disclosures for segment reporting. The guidance is effective for the Company beginning in the first quarter of fiscal 2025. We are currently evaluating the impact that the updated standard will have on our financial statement disclosures.

In December 2023, the FASB issued ASU 2023-09 Income Taxes (Topic 740), which requires enhanced disclosures for income taxes. The guidance is effective for the Company beginning in the first quarter of fiscal 2026. Early adoption is permitted. We are currently evaluating the impact that the updated standard will have on our financial statement disclosures.

The Company does not believe that any other recently issued accounting standards will have a material impact on its Consolidated Financial Statements or apply to its operations.

Fair Value of Financial Instruments

Fair Value Measurements:

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 Company uses quoted market prices when available or discounted cash flows to calculate fair value. 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.
