NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

Unaudited

NOTE 1. BASIS OF PRESENTATION

These consolidated condensed financial statements include the accounts of Kulicke and Soffa Industries, Inc. and its subsidiaries (“K&S,” “we,” “us,” “our,” or the “Company”), with appropriate elimination of intercompany balances and transactions.

The interim consolidated condensed financial statements are unaudited and, in management’s opinion, include all adjustments (consisting only of normal and recurring adjustments) necessary for a fair statement of results for these interim periods. The interim consolidated condensed financial statements do not include all of the information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 28, 2024 (the “2024 Annual Report”) filed with the Securities and Exchange Commission on November 14, 2024, which includes the Consolidated Balance Sheets as of September 28, 2024 and September 30, 2023, and the related Consolidated Statements of Operations, Statements of Comprehensive Income, Changes in Shareholders’ Equity and Cash Flows for each of the years in the three-year period ended September 28, 2024. The results of operations for any interim period are not necessarily indicative of the results of operations for any other interim period or for a full year.

Fiscal Year

Each of the Company’s first three fiscal quarters end on the Saturday that is 13 weeks after the end of the immediately preceding fiscal quarter. The fourth quarter of each fiscal year ends on the Saturday closest to September 30. Fiscal 2025 quarters end on December 28, 2024, March 29, 2025, June 28, 2025 and October 4, 2025. In fiscal years consisting of 53 weeks, the fourth quarter will consist of 14 weeks. Fiscal 2024 quarters ended on December 30, 2023, March 30, 2024, June 29, 2024 and September 28, 2024.

Nature of Business

The Company designs, develops, manufactures and sells capital equipment and tools as well as services, maintains, repairs and upgrades equipment, all used to assemble semiconductor devices. The Company’s operating results depend upon the capital and operating expenditures of integrated device manufacturers (“IDMs”), outsourced semiconductor assembly and test providers (“OSATs”), foundry service providers, and other electronics manufacturers and automotive electronics suppliers worldwide which, in turn, depend on the current and anticipated market demand for semiconductors and products utilizing semiconductors. The semiconductor industry is highly volatile and experiences downturns and slowdowns which can have a severe negative effect on the semiconductor industry’s demand for semiconductor capital equipment, including assembly equipment manufactured and sold by the Company and, to a lesser extent, tools, solutions and services, including those sold or provided by the Company. These downturns and slowdowns have in the past adversely affected the Company’s operating results. The Company believes such volatility will continue to characterize the industry and the Company’s operations in the future.

Use of Estimates

The preparation of consolidated condensed financial statements requires management to make assumptions, estimates and judgments that affect the reported amounts of assets and liabilities, net revenue and expenses during the reporting periods, and disclosures of contingent assets and liabilities as of the date of the consolidated condensed financial statements. On an ongoing basis, management evaluates estimates, including but not limited to, those related to accounts receivable, reserves for excess and obsolete inventory and inventory valuation, carrying value and lives of fixed assets, goodwill and intangible assets, accrual for customer credit programs, the valuation estimates and assessment of impairment and observable price adjustments, income taxes, equity-based compensation expense, accrual for employee termination benefits and warranties. Management bases its estimates on historical experience and on various other assumptions believed to be reasonable. As a result, management makes judgments regarding the carrying values of the Company’s assets and liabilities that are not readily apparent from other sources. Authoritative pronouncements, historical experience and assumptions are used as the basis for making estimates, and on an ongoing basis, management evaluates these estimates. Actual results may differ from these estimates.

In light of macroeconomic headwinds, there has been uncertainty and disruption in the global economy and financial markets. The Company is not aware of any specific event or circumstance that would require an update to its estimates or judgments or a revision of the carrying value of its assets or liabilities as of December 28, 2024. While there was no material impact from macroeconomic headwinds to our consolidated condensed financial statements as of and for the quarter ended December 28, 2024, these estimates may change, as new events occur and additional information is obtained, including factors related to these headwinds, that could materially impact our consolidated condensed financial statements in future reporting periods.

Significant Accounting Policies

There have been no material changes to our significant accounting policies summarized in Note 1: Basis of Presentation to our Consolidated Financial Statements included in our 2024 Annual Report.

Recent Accounting Pronouncements

Disclosure Improvements

In October 2023, the Financial Accounting Standards Board (the "FASB") issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. This ASU aligns the requirements in the FASB Accounting Standards Codification with the SEC’s regulations. The amendments in the ASU are expected to clarify or improve disclosure and presentation requirements over a variety of Codification Topics. They will also allow users to more easily compare entities subject to the SEC’s existing disclosures with those entities that were not previously subject to the requirements, and align the requirements in the Codification with the SEC’s regulations. This ASU will become effective for each amendment on the date on which the SEC removes the related disclosure from its regulations. However, if by June 30, 2027, the SEC has not removed the related disclosure from its regulations, the amendments will be removed from the Codification and not become effective for any entity. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements.

Segment Reporting

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosure, which aims to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. In addition, the amendments in the ASU enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The purpose of the amendments is to enable investors to better understand an entity's overall performance and assess potential future cash flows. This ASU will be effective for the Company's fiscal year 2025, and interim periods within the fiscal years beginning after the Company’s fiscal year 2026. Early adoption is permitted. The Company will include the required Segment Reporting disclosures within the Notes to Financial Statements with the filing of its Annual Report on Form 10-K for the year ending on October 4, 2025.

Income Taxes

In December 2023, the FASB issued ASU 2023-09 Income Taxes (Topic 740): Improvement to Income Tax Disclosures. The amendments in this update are intended to enhance the transparency and decision usefulness of income tax disclosures primarily through changes to the rate reconciliation and income taxes paid information. This ASU will be effective for the Company's fiscal year 2026. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. ASU 2023-09 should be applied on a prospective basis, but retrospective application is permitted. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements.

Disaggregation of Income Statement Expenses

In November 2024, the FASB issued ASU 2024-03 Income Statement - Reporting Comprehensive Income -Expense Disaggregation Disclosures (Topic 220): Disaggregation of Income Statement Expenses. This ASU requires disclosure of certain expenses in the notes to the financial statements. This ASU will be effective for the Company's fiscal 2028 on a prospective basis, with retrospective application permitted. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements.

NOTE 3. GOODWILL AND INTANGIBLE ASSETS

Goodwill

Intangible assets classified as goodwill are not amortized. The goodwill established in connection with our acquisitions represents the estimated future economic benefits arising from the assets we acquired that did not qualify to be identified and recognized individually. The goodwill also includes the value of expected future cash flows from the acquisitions, expected synergies with our other affiliates and other unidentifiable intangible assets.

The Company performs an annual impairment test of its goodwill during the fourth quarter of each fiscal year, which coincides with the completion of its annual forecasting and refreshing of business outlook process.

The Company performed its annual impairment test in the fourth quarter of fiscal 2024 and concluded that no impairment charge was required. Any future adverse changes in expected operating results and/or unfavorable changes in other economic factors used to estimate fair values could result in a non-cash impairment in the future.

During the three months ended December 28, 2024, the Company reviewed qualitative factors to ascertain if a “triggering” event may have taken place that may have the effect of reducing the fair value of the reporting unit below its carrying value and concluded that no triggering event had occurred. While we have concluded that a triggering event did not occur during the quarter ended December 28, 2024, the persistent macroeconomic headwinds could, in the future, require changes to assumptions utilized in the determination of the estimated fair values of the reporting units which could result in future goodwill impairment charges. Net sales and earnings growth rates could be negatively impacted by reductions or changes in demand for our products. The discount rate utilized in our valuation model could also be impacted by changes in the underlying interest rates and risk premiums included in the determination of the cost of capital.

The following table summarizes the changes in the Company’s recorded goodwill, where applicable, by reportable segments and the “All Others” category (refer to Note 14 for further information) as of December 28, 2024 and September 28, 2024:


(in thousands)	Wedge Bonding Equipment		APS		All Others	Total
Balance at September 28, 2024(1)	$	18,280	$	26,268	45,200	$	89,748

Balance at December 28, 2024	$	18,280	$	26,070	44,061	$	88,411

Equity investments consisted of the following as of December 28, 2024 and September 28, 2024:


	As of
(in thousands)	December 28, 2024		September 28, 2024


Non-marketable equity securities	$	3,385	$	3,143

Net Asset Value (“NAV”) (Private Equity Fund): Equity investments in affiliated investment funds are valued based on the NAV reported by the investment fund in accordance with ASC Topic 820-10. Investments held by the affiliated investment fund include a diversified portfolio of investments in the global semiconductor industry. The Company receives distributions through the liquidation of the underlying investments by the affiliated investment fund. However, the period of time over which the underlying investments are expected to be liquidated is unknown. Additionally, the Company’s ability to withdraw from the fund is subject to restrictions. The term of the fund will continue until March 18, 2032, unless dissolved earlier or otherwise extended by the General Partner. In accordance with ASC Topic 820-10, this investment is measured at fair value using the NAV per share (or its equivalent) practical expedient and has not been classified in the fair value hierarchy. As of December 28, 2024, the Company has funded $3.8 million into the affiliated investment fund and recognized a cumulative unrealized fair value loss of $0.4 million. The Company has recorded the amount of funded capital that has been called as an equity investment.

NOTE 6. FAIR VALUE MEASUREMENTS

Accounting standards establish three levels of inputs that may be used to measure fair value: quoted prices in active markets for identical assets or liabilities (referred to as Level 1), inputs other than Level 1 that are observable for the asset or liability either directly or indirectly (referred to as Level 2) and unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities (referred to as Level 3).

Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis

We measure certain financial assets and liabilities as described in Note 4 and 5 at fair value on a recurring basis. There were no transfers between fair value measurement levels during the three months ended December 28, 2024.

Fair Value Measurements on a Nonrecurring Basis

Our non-financial assets such as intangible assets and property, plant and equipment are carried at cost unless impairment is deemed to have occurred.

Fair Value of Financial Instruments

Amounts reported as accounts receivables, prepaid expenses and other current assets, accounts payable and accrued expenses approximate fair value.

NOTE 7. DERIVATIVE FINANCIAL INSTRUMENTS

The Company’s international operations are exposed to changes in foreign exchange rates due to transactions denominated in currencies other than U.S. dollars. Most of the Company’s revenue and cost of materials are transacted in U.S. dollars. However, a significant amount of the Company’s operating expenses is denominated in local currencies, primarily in Singapore.

Table of Contents

KULICKE AND SOFFA INDUSTRIES, INC.

NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

Unaudited (continued)

The foreign currency exposure of our operating expenses is generally hedged with foreign exchange forward contracts. The Company’s foreign exchange risk management programs include using foreign exchange forward contracts with cash flow hedge accounting designation to hedge exposures to the variability in the U.S. dollar equivalent of forecasted non-U.S. dollar-denominated operating expenses. These instruments generally mature within twelve months. For these derivatives, we report the after-tax gain or loss from the effective portion of the hedge as a component of accumulated other comprehensive income (loss), and we reclassify it into earnings in the same period or periods in which the hedged transaction affects earnings and in the same line item on the Consolidated Condensed Statements of Operations as the impact of the hedged transaction.

The fair value of derivative instruments on our Consolidated Condensed Balance Sheets as of December 28, 2024 and September 28, 2024 were as follows:

NOTE 8. LEASES

We have entered into various non-cancellable operating and finance lease agreements for certain of our offices, manufacturing, technology, sales support and service centers, equipment, and vehicles. We determine if an arrangement is a lease, or contains a lease, at inception and record the leases in our financial statements upon lease commencement, which is the date when the underlying asset is made available for use by the lessor. Our lease terms may include one or more options to extend the lease terms, for periods from one year to 20 years, when it is reasonably certain that we will exercise that option. As of December 28, 2024, there were no options to extend the lease which was recognized as a right-of-use (“ROU”) asset, or a lease liability. We have lease agreements with lease and non-lease components, and non-lease components are accounted for separately and not included in our leased assets and corresponding liabilities. We have elected not to present short-term leases on the Consolidated Condensed Balance Sheets as these leases have a lease term of 12 months or less at lease inception.

Operating leases are included in operating ROU assets, current operating lease liabilities and non-current operating lease liabilities, and finance leases are included in property, plant and equipment, accrued expenses and other current liabilities, and other liabilities on the Consolidated Condensed Balance Sheets. As of December 28, 2024 and September 28, 2024, our finance leases are not material.

NOTE 9. DEBT AND OTHER OBLIGATIONS

Bank Guarantees

On November 22, 2013, the Company obtained a $5.0 million credit facility with Citibank in connection with the issuance of bank guarantees for operational purposes. As of December 28, 2024, the outstanding amount under this facility was $4.7 million.

Credit Facilities

On February 15, 2019, the Company entered into a Facility Letter and Overdraft Agreement (collectively, the “Facility Agreements”) with MUFG Bank, Ltd., Singapore Branch (the “Bank”). The Facility Agreements provide the Company and one of its subsidiaries with an overdraft facility of up to $150.0 million (the “Overdraft Facility”) for general corporate purposes. Amounts outstanding under the Overdraft Facility, including interest, are payable upon thirty days written demand by the Bank. Interest on the Overdraft Facility is calculated on a daily basis, and the applicable interest rate is calculated at the Secured Overnight Financing Rate (“SOFR”) plus a margin of 1.5% per annum. The Overdraft Facility is an unsecured facility per the terms of the Facility Agreements. The Facility Agreements contain customary non-financial covenants, including, without limitation, covenants that restrict the Company’s ability to sell or dispose of its assets, cease owning at least 51% of two of its subsidiaries (the “Subsidiaries”), or encumber its assets with material security interests (including any pledge of monies in the Subsidiaries' cash deposit account with the Bank). The Facility Agreements also contain typical events of default, including, without limitation, non-payment of financial obligations when due, cross defaults to other material indebtedness of the Company and any breach of a representation or warranty under the Facility Agreements. As of December 28, 2024, there were no outstanding amounts under the Overdraft Facility.

NOTE 10. SHAREHOLDERS’ EQUITY AND EMPLOYEE BENEFIT PLANS

Share Repurchase Program

On August 15, 2017, the Company’s Board of Directors authorized a program to repurchase up to $100 million of the Company’s common stock on or before August 1, 2020. In 2018, 2019, 2020 and 2022, the Board of Directors increased the share repurchase authorization to $200 million, $300 million, $400 million and $800 million, respectively, and extended its duration through August 1, 2025 (the "Prior Program").

During the three months ended December 28, 2024, the Company repurchased a total of approximately 657.0 thousand shares of common stock under the Prior Program at a cost of approximately $30.3 million. On December 2, 2024, the Company announced that it has completed share repurchases under the Prior Program.

Additionally, and as previously announced on November 13, 2024, the Board of Directors authorized a new share repurchase program to repurchase up to $300 million of the Company's common stock (the "New Program"), with the intention that the New Program initiate upon the completion of the Prior Program.

Contemporaneously, on December 2, 2024, the Company entered into a new written trading plan under Rule 10b5-1 of the Exchange Act, to facilitate repurchases under the New Program. The plan permits the purchase of up to approximately $300 million of the Company’s common stock from December 2, 2024 through December 2, 2029. The New Program may be suspended or discontinued at any time and is funded using the Company’s available cash, cash equivalents and short-term investments. Under the New Program, shares may be repurchased through open market and/or privately negotiated transactions at prices deemed appropriate by management. The timing and amount of repurchase transactions under the New Program depend on market conditions as well as corporate and regulatory considerations.

During the three months ended December 28, 2024, the Company repurchased a total of approximately 136.0 thousand shares of common stock under the New Program at a cost of approximately $6.6 million.

The stock repurchases were recorded in the periods the repurchased shares were delivered and accounted for as treasury stock in the Company’s Consolidated Condensed Balance Sheets. The Company records treasury stock purchases under the cost method using the first-in, first-out (FIFO) method. Upon re-issuance of treasury stock, amounts in excess of the acquisition cost are credited to additional paid-in capital.

If the Company reissues treasury stock at an amount below its acquisition cost and additional paid-in capital associated with prior treasury stock transactions is insufficient to cover the difference between acquisition cost and the reissue price, this difference is recorded against retained earnings.

As of December 28, 2024, our remaining stock repurchase authorization under the New Program was approximately $293.4 million.

Dividends

On November 13, 2025, the Board of Directors declared a quarterly dividend of $0.205 per share of common stock, representing a $0.005 increase over the last quarterly dividend. Dividends paid during the three months ended December 28, 2024 totaled $10.8 million. The declaration of any future cash dividend is at the discretion of the Board of Directors and will depend on the Company’s financial condition, results of operations, capital requirements, business conditions and other factors, as well as a determination that such dividends are in the best interests of the Company’s shareholders.

Equity-Based Compensation

The Company has a stockholder-approved equity-based compensation plan, the 2021 Omnibus Incentive Plan (the “Plan”) from which employees and directors receive grants. As of December 28, 2024, 1.1 million shares of common stock are available for grant to the Company’s employees and directors under the Plan.

•Relative Total Shareholder Return Performance Share Units (“Relative TSR PSUs”) entitle the employee to receive common stock of the Company on the award vesting date, typically the third anniversary of the grant date (or as soon as administratively practicable if later), if market performance objectives which measure the relative TSR are attained. Relative TSR is calculated based upon the 90-calendar day average price at the end of the performance period of the Company’s stock as compared to specific peer companies that comprise the GICS (45301020) Semiconductor Index. TSR is measured for the Company and each peer company over a performance period, which is generally three years. Vesting percentages range from 0% to 200% of awards granted. The provisions of the Relative TSR PSUs are reflected in the grant date fair value of the award; therefore, compensation expense is recognized regardless of whether the market condition is ultimately satisfied. Compensation expense is reversed if the award is forfeited prior to the vesting date.

•Revenue Growth Performance Share Units (“Growth PSUs”) entitle the employee to receive common stock of the Company on the award vesting date, typically the third anniversary of the grant date (or as soon as administratively practicable if later), based on organic revenue growth objectives and relative growth performance against named competitors as set by the Management Development and Compensation Committee (“MDCC”) of the Company’s Board of Directors. Organic revenue growth is calculated by averaging revenue growth (net of revenues from acquisitions) over a performance period, which is generally three years. Revenues from acquisitions will be included in the calculation after four fiscal quarters after acquisition. Any portion of the grant that does not meet the revenue growth objectives and relative growth performance is forfeited. Vesting percentages range from 0% to 200% of awards granted.

•In general, Time-based Restricted Share Units (“Time-based RSUs”) awarded to employees vest ratably over a three-year period on the anniversary of the grant date provided the employee remains employed by the Company.

Equity-based compensation expense recognized in the Consolidated Condensed Statements of Operations for the three months ended December 28, 2024 and December 30, 2023 was based upon awards ultimately expected to vest, with forfeiture accounted for when they occur.

NOTE 11. REVENUE AND CONTRACT BALANCES

The Company recognizes revenue when we satisfy performance obligations as evidenced by the transfer of control of our products or services to customers. In general, the Company generates revenue from product sales, either directly to customers or to distributors. In determining whether a contract exists, we evaluate the terms of the agreement, the relationship with the customer or distributor and their ability to pay. Service revenue is generally recognized over time as the services are performed. For the three months ended December 28, 2024 and December 30, 2023, the service revenue was not material.

The Company reports revenue based on its reportable segments and end markets, which provides information about how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. Please refer to Note 14: Segment Information, for disclosure of revenue by segment and end markets.

For the three months ended December 28, 2024, the increase in provision for income taxes and the decrease in the effective tax rate was primarily due to the reimbursement from Project W cancellation which was recorded as a discrete item in the quarter.

For the three months ended December 28, 2024, the effective tax rate is different than the U.S. federal statutory tax rate primarily due to earnings of foreign subsidiaries subject to tax at different rates than the U.S., tax incentives, tax credits, changes in valuation allowances, the impact of Global Intangible Low-Taxed Income, and the tax impact from the reimbursement of Project W cancellation.

NOTE 14. SEGMENT INFORMATION

Reportable segments are defined as components of an enterprise that engage in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker (the “CODM”) in deciding how to allocate resources and assess performance. The Company’s Chief Executive Officer is the CODM. The CODM does not review discrete asset information.

The Company has four reportable segments consisting of: (1) Ball Bonding Equipment, (2) Wedge Bonding Equipment, (3) Advanced Solutions, and (4) Aftermarket Products and Services (“APS”). The four reportable segments are disclosed below:

OVERVIEW

Founded in 1951, Kulicke and Soffa Industries, Inc. (“K&S,” “we,” “us,” “our,” or the “Company”) specializes in developing cutting-edge semiconductor and electronics assembly solutions enabling a smarter and more sustainable future. Our ever-growing range of products and services supports growth and facilitates technology transitions across large-scale markets, such as advanced display, automotive, communications, compute, consumer, data storage, energy storage and industrial.

We design, develop, manufacture and sell capital equipment and consumables and provide services used to assemble semiconductor and electronic devices, such as integrated circuits, power discretes, light-emitting diode (“LEDs”), advanced displays and sensors. We also service, maintain, repair and upgrade our equipment and sell consumable aftermarket solutions and services for our and our peer companies’ equipment. Our customers primarily consist of integrated device manufacturers (“IDMs”), outsourced semiconductor assembly and test providers (“OSATs”), foundry service providers, and other electronics manufacturers and automotive electronics suppliers.

Our goal is to be the technology leader and the most competitive supplier in terms of performance, cost and quality in each of our major product lines. Accordingly, we invest in research and engineering projects intended to expand our market access and enhance our leadership position in semiconductor, electronics and display assembly. We also remain focused on enhancing our value to customers through higher productivity systems, more autonomous capabilities and continuous improvement and optimization of our operational costs. Delivering new levels of value to our customers is a critically important goal.

Our Ball Bonding Equipment, Wedge Bonding Equipment and Advanced Solutions reportable segments engage in the design, development, manufacture and sale of ball bonding equipment, wafer level bonding equipment, wedge and wedge-related bonding equipment, certain advanced display, die-attach and thermocompression systems and solutions to IDMs, OSATs, foundry service providers, and other electronics manufacturers and automotive electronics suppliers.

Our APS segment engages in the design, development, manufacture and sale of a variety of tools, spares and services for our equipment. For example, we manufacture capillaries, blades, wedge bonder consumables and other spare parts which complements our equipment and to support a broader range of semiconductor packaging applications. We also provide equipment repair, post-sale support, maintenance and servicing, training services, refurbishment and upgrades for our equipment.

All other operating segments that do not meet the quantitative threshold to be disclosed as a separate reportable segment have been grouped within an “All Others” category. This group is reflective of the results of the Company from the design, development, manufacture and sale of certain advanced display, advanced dispense, electronics assembly, and die-attach systems and solutions.

Business Environment

The semiconductor business environment is highly volatile and is driven by internal dynamics, both cyclical and seasonal, in addition to macroeconomic forces. Over the long term, semiconductor consumption has historically grown, and is forecasted to continue to grow. This growth is driven, in part, by regular advances in device performance and by price declines that result from improvements in manufacturing technology. In order to exploit these trends, semiconductor manufacturers, both IDMs and OSATs, periodically invest aggressively in the latest generation capital equipment. This buying pattern often leads to periods of excess supply and reduced capital spending — the so-called semiconductor cycle. Within this broad semiconductor cycle there are also, generally weaker, seasonal effects that are specifically tied to annual, end-consumer purchasing patterns. Typically, semiconductor manufacturers prepare for heightened demand by adding or replacing equipment capacity by the end of the September quarter. Occasionally, this results in subsequent reductions in demand during the December quarter. This annual seasonality can be overshadowed by effects of the broader semiconductor cycle. Macroeconomic factors also affect the industry, primarily through their effect on business and consumer demand for electronic devices, as well as other products that have significant electronic content such as automobiles, white goods, and telecommunication equipment. There can be no assurances regarding levels of demand for our products and we believe historic industry-wide volatility will persist.

From time to time, our customers may request that we deliver our products to countries where they own or operate production facilities or to countries where they utilize third-party subcontractors or warehouses as part of their supply chain. For example, customers headquartered in the U.S. may require us to deliver our products to their back-end production facilities in China. Our customer base in the Asia/Pacific region has become more geographically concentrated over time as a result of general economic and industry conditions and trends. Approximately 87.2% and 89.9% of our net revenue for the three months ended December 28, 2024 and December 30, 2023, respectively, were for shipments to customer locations outside of the U.S., primarily in the Asia/Pacific region. Approximately 48.9% and 46.2% of our net revenue for the three months ended December 28, 2024 and December 30, 2023, respectively, were for shipments to customers headquartered in China.

While our customers have generally been impacted by the current global macroeconomic conditions, those with operations in China, an important manufacturing and supply chain hub, have witnessed a faster decline in demand and, accordingly, a faster decline in product shipments, compared to the rest of the world. The shipments to customers headquartered in China are subject to heightened risks and uncertainties related to the respective trade and export control policies of the governments of China and the U.S. Furthermore, there remains a potential risk of conflict and instability in the relationship between Taiwan and China that could disrupt the operations of our customers and/or suppliers in both Taiwan and China and our manufacturing operations in Taiwan and China.

The U.S. and several other countries have levied tariffs on certain goods and have introduced other trade restrictions resulting in substantial uncertainties in the semiconductor, LED, memory and automotive markets.

Our Ball Bonding Equipment, Wedge Bonding Equipment and Advanced Solutions reportable segments, as well as the remaining operating segments in the “All Others” category, are primarily affected by the industry’s internal cyclical and seasonal dynamics in addition to broader macroeconomic factors that can positively or negatively affect our financial performance. The sales mix of IDM and OSAT customers in any period also impacts financial performance, as changes in this mix can affect our products’ average selling prices and gross margins due to differences in volume purchases and machine configurations required by each customer type.

Our APS reportable segment has historically been less volatile than the other reportable segments. APS sales are more directly tied to semiconductor unit consumption rather than capacity requirements and production capability improvements.

We continue to position our business to leverage our research and development leadership and innovation and to focus our efforts on mitigating volatility, improving profitability and ensuring longer-term growth. We remain focused on operational excellence, expanding our product offerings through continuous research and development or acquisitions and managing our business efficiently throughout the business cycles. However, our visibility into future demand is generally limited, forecasting is difficult, and we generally experience typical industry seasonality.

To limit potential adverse cyclical, seasonal and macroeconomic effects on our financial position, we have continued our efforts to maintain a strong balance sheet. As of December 28, 2024, our total cash, cash equivalents and short-term investments were $538.3 million, a $38.8 million decrease from the prior fiscal year end. We believe our ability to maintain a strong cash position will allow us to continue to invest in product development, pursue non-organic growth opportunities and return capital to investors through our share repurchase and dividend programs. Please see “Liquidity and Capital Resources” for more information.

Key Events in Fiscal 2025 to Date

Cancellation of Project W

Macroeconomic Headwinds

The cost of logistics remains high as a result of macroeconomic conditions, inflation and labor shortages across layers of the supply chain. The Company’s management continues to monitor for signs of any expansion of economic or supply chain disruptions or broader supply chain inflationary and logistical costs resulting either directly or indirectly from the tensions in the Middle East or between Ukraine and Russia.

The ongoing tensions in the Middle East and the prolonged Ukraine/Russia conflict have not had a material impact on our financial condition and operating results in fiscal 2025 to date. We believe that our existing cash, cash equivalents, short-term investments, existing Facility Agreements, and anticipated cash flows from operations will be sufficient to meet our liquidity and capital requirements, notwithstanding the ongoing tensions in the Middle East and the prolonged Ukraine/Russia conflict and other macroeconomic factors, for at least the next twelve months from the date of this Quarterly Report. However, this is a highly dynamic situation. As the macroeconomic situation remains highly volatile and the geopolitical situation remains uncertain, there is uncertainty surrounding the operations of our manufacturing locations, our business, our expectations regarding future demand or supply conditions, our near- and long-term liquidity and our financial condition. Consequentially, our operating results could deteriorate.

During fiscal years 2021 and 2022, semiconductor suppliers rapidly increased production output in response to increases in end-consumer demand. Concerns surrounding supply availability spurred defensive inventory purchases, which led to a heightened demand for our products.

The current macroeconomic conditions and declining consumer sentiment during fiscal years 2023 and 2024 have persisted, which continues to exacerbate inventory buildup in the semiconductor industry. Many of our customers who accumulated our products in the past three years continue to reduce their order rates as a result of inventory adjustment.

Due to general inflationary pressures, declining consumer sentiment, and an economic downturn caused, directly or indirectly, by various macroeconomic factors, including the ongoing tensions in the Middle East and the prolonged Ukraine/Russia conflict, the sector continues to experience volatility and disruption. However, we believe that the long-term semiconductor industry macroeconomics have not changed and we anticipate that the industry’s growth projections will normalize.

For a description of the risks to our business arising from or relating to the general macroeconomic conditions, please see Part I, Item 1A, “Risk Factors” of our 2024 Annual Report.

For the three months ended December 28, 2024, interest income decreased as compared to the prior year period primarily due to a lower average balances of cash, cash equivalents and short-term investments.

Cash and cash equivalents, end of period	$	278,325	$	424,660

Three months ended December 28, 2024

The increase in net cash used in operating activities was primarily due to a net income of $81.6 million and non-cash adjustments to net income of $6.4 million, partially offset by a net unfavourable change in operating assets and liabilities of $69.1 million. The net change in operating assets and liabilities was primarily driven by an increase in accounts and other receivable of $53.9 million, an increase in inventories of $9.1 million, and a decrease in accounts payable and accrued expenses and other current liabilities of $15.8 million . This was partially offset by an increase in income tax payable of $9.8 million and a decrease in prepaid expenses and other current assets of $1.9 million.

The increase in accounts and other receivable in the three months ended December 28, 2024 was mainly due to the timing of payments due. The increase in inventories was due to the buildup of long lead time materials to fulfill certain customer purchase orders. The decrease in accounts payable and accrued expenses and other current liabilities was primarily due to lower customer advances, accrued employee compensation and lower material purchases. The increase in income tax payable was primarily due to higher profitability which included the reimbursement from Project W cancellation which was recorded as a discrete item in the quarter.

Net cash provided by investing activities was due to net maturity of short-term investments of $90.0 million and net cash received from the disposal of a subsidiary of $2.6 million, and offset by capital expenditures of $10.2 million and investment in a private equity fund of $0.4 million.

Net cash used in financing activities was primarily due to common stock repurchases of $37.2 million and dividend payments of $10.8 million.

Three months ended December 30, 2023

Net cash used in operating activities was primarily due to net income of $9.3 million, non-cash adjustments to net income of $20.4 million and a net unfavorable change in operating assets and liabilities of $37.0 million. The net change in operating assets and liabilities was primarily driven by a increase in accounts and other receivable of $25.6 million, an increase in inventories of $22.1 million and a decrease in accounts payable and accrued expenses and other current liabilities of $0.8 million. This was partially offset by an decrease in prepaid expenses and other current assets of $7.5 million and an increase income tax payable of $2.4 million.

The increase in accounts and other receivable in the three months ended December 30, 2023 was mainly due to the timing of payments due. The increase in inventories was due to the buildup of long lead time materials to fulfill certain customer purchase orders. The decrease in accounts payable and accrued expenses and other current liabilities was primarily due to lower accrued employee compensation that was paid out in the period, partially offset by higher material purchases during the period. The decrease in prepaid expenses was mainly due the transfer of contract assets to net account receivables.

Net cash used in investing activities was due to net purchase of short-term investments of $55.0 million, capital expenditures of $4.4 million and investment in private equity fund of $1.1 million.

Net cash used in financing activities was primarily due to common stock repurchases of $27.2 million and dividend payments of $10.7 million.

Fiscal 2025 Liquidity and Capital Resource Outlook

We expect our aggregate fiscal 2025 capital expenditures to be between approximately $13.0 million and $17.0 million, of which approximately $2.1 million has been incurred through the first quarter. The actual amounts for 2025 will vary depending on market conditions. Expenditures are anticipated to be primarily for research and development projects, enhancements to our manufacturing operations, improvements to our information technology security, implementation of an enterprise resource planning system and leasehold improvements for our facilities. Our ability to make these expenditures will depend, in part, on our future cash flows, which are determined by our future operating performance and, therefore, subject to prevailing macroeconomic conditions, including actual or potential inflationary pressures, supply chain challenges, geopolitical tensions and other factors, some of which are beyond our control.

As of December 28, 2024 and September 28, 2024, approximately $313.8 million and $302.6 million of cash, cash equivalents, and short-term investments, respectively, were held by the Company’s foreign subsidiaries, with a large portion of the cash amounts expected to be available for use in the U.S. without incurring additional U.S. income tax. The decrease is primarily due to the repatriation of cash held by the Company's foreign subsidiaries to the U.S.

The Company’s operations and capital requirements are anticipated to be funded primarily by cash on hand, cash generated from operating activities, and cash from our existing Facility Agreements (as defined below). We believe these sources of cash and liquidity are sufficient to meet our additional liquidity needs for the foreseeable future, including repayment of outstanding balances under the Facility Agreements, as well as payment of dividends, share repurchases and income taxes.

We believe that our existing cash, cash equivalents, short-term investments, existing Facility Agreements, and anticipated cash flows from operations will be sufficient to meet our liquidity and capital requirements, notwithstanding the macroeconomic headwinds, for at least the next twelve months and beyond. Our liquidity is affected by many factors, some based on normal operations of our business and others related to macroeconomic conditions including actual or potential inflationary pressures, industry-related uncertainties, and effects arising from the ongoing tensions in the Middle East and the prolonged Ukraine/Russia conflict, which we cannot predict. We also cannot predict economic conditions or industry downturns or the timing, strength or duration of recoveries. We intend to continue to use our cash for working capital needs and for general corporate purposes.

In this unprecedented macroeconomic environment, we may seek, as we believe appropriate, additional debt or equity financing that would provide capital for general corporate purposes, working capital funding, additional liquidity needs or to fund future growth opportunities, including possible acquisitions. The timing and amount of potential capital requirements cannot be determined at this time and will depend on a number of factors, including the actual and projected demand for our products, semiconductor and semiconductor capital equipment industry conditions, competitive factors, the condition of financial markets and the global economic situation.

Share Repurchase Program

During the three months ended December 28, 2024, the Company repurchased a total of approximately 136.0 thousand shares of common stock under the New Program at a cost of approximately $6.6 million.

As of December 28, 2024, our remaining stock repurchase authorization under the New Program was approximately $293.4 million.

Dividends

On November 13, 2024, the Board of Directors declared a quarterly dividend of $0.205 per share of common stock. Dividends paid during the three months ended December 28, 2024 totaled $10.8 million. The declaration of any future cash dividend is at the discretion of the Board of Directors and will depend on the Company’s financial condition, results of operations, capital requirements, business conditions and other factors, as well as a determination that such dividends are in the best interests of the Company’s shareholders.

Other Obligations and Contingent Payments

In accordance with U.S. GAAP, certain obligations and commitments are not required to be included in the Consolidated Condensed Balance Sheets and Statements of Operations. These obligations and commitments, while entered into in the normal course of business, may have a material impact on our liquidity and are disclosed in the table below.

As of December 28, 2024, the Company had deferred tax liabilities of $34.7 million and unrecognized tax benefits within the income taxes payable for uncertain tax positions of $19.7 million, inclusive of accrued interest on uncertain tax positions of $4.0 million, substantially all of which would affect our effective tax rate in the future, if recognized.

Table of Contents

It is reasonably possible that the amount of the unrecognized tax benefit with respect to certain unrecognized tax positions will increase or decrease during the next twelve months due to the expected lapse of statutes of limitation and / or settlements of tax examinations. Given the number of years and numerous matters that remain subject to examination in various tax jurisdictions, we cannot practicably estimate the timing or financial outcomes of these examinations and, therefore, these amounts are excluded from the amounts below.

The following table presents certain payments due by the Company under contractual and statutory obligations with minimum firm commitments as of December 28, 2024:


			Payments due in
(in thousands)	Total		Less than 1 year		1 - 3 years		3 - 5 years		More than 5 years
Inventory purchase obligations (1)	$	137,052	$	47,166	$	89,886	$	—	$	—

U.S. one-time transition tax payable (2) (reflected on our Consolidated Condensed Balance Sheets)	$	28,619	16,808		11,811		—		—

Total	$	165,671	$	63,974	$	101,697	$	—	$	—

(1)The Company orders inventory components in the normal course of its business. A portion of these orders are non-cancellable and some orders impose varying penalties and charges in the event of cancellation.

(2)Associated with the U.S. one-time transition tax on certain earnings and profits of our foreign subsidiaries in relation to the U.S. Tax Cuts and Job Act of 2017.

Credit facilities

On February 15, 2019, the Company entered into a Facility Letter and Overdraft Agreement (collectively, the “Facility Agreements”) with MUFG Bank, Ltd., Singapore Branch (the “Bank”). The Facility Agreements provide the Company and one of its subsidiaries with an overdraft facility of up to $150.0 million (the “Overdraft Facility”) for general corporate purposes. Amounts outstanding under the Overdraft Facility, including interest, are payable upon thirty days written demand by the Bank. Interest on the Overdraft Facility is calculated on a daily basis, and the applicable interest rate is calculated at the Secured Overnight Financing Rate (“SOFR”) plus a margin of 1.5% per annum. The Overdraft Facility is an unsecured facility per the terms of the Facility Agreements. The Facility Agreements contain customary non-financial covenants, including, without limitation, covenants that restrict the Company’s ability to sell or dispose of its assets, cease owning at least 51% of two of its subsidiaries (the “Subsidiaries”) or encumber its assets with material security interests (including any pledge of monies in the Subsidiaries’ cash deposit account with the Bank). The Facility Agreements also contain typical events of default, including, without limitation, non-payment of financial obligations when due, cross defaults to other material indebtedness of the Company, and breach of a representation or warranty under the Facility Agreements. As of December 28, 2024, there were no outstanding amounts under the Overdraft Facility.

As of December 28, 2024, other than the bank guarantee disclosed in Note 9 of Item 1, we did not have any other off-balance sheet arrangements, such as contingent interests or obligations associated with variable interest entities.

Item 3. - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

Our available-for-sale securities, if applicable, may consist of short-term investments in highly rated debt instruments of the U.S. Government and its agencies, financial institutions, and corporations. We continually monitor our exposure to changes in interest rates and credit ratings of issuers with respect to any available-for-sale securities and target an average life to maturity of less than 18 months. Accordingly, we believe that the effects on us of changes in interest rates and credit ratings of issuers are limited and would not have a material impact on our financial condition or results of operations.

Foreign Currency Risk

Our international operations are exposed to changes in foreign currency exchange rates due to transactions denominated in currencies other than the location’s functional currency. Our international operations are also exposed to foreign currency fluctuations that impact the remeasurement of net monetary assets of those operations whose functional currency, the U.S. dollar, differs from their respective local currencies, most notably in Israel, Singapore and Switzerland. Our U.S. operations also have foreign currency exposure due to net monetary assets denominated in currencies other than the U.S. dollar. In addition to net monetary remeasurement, we have exposures related to the translation of subsidiary financial statements from their functional currency, the local currency, into its reporting currency, the U.S. dollar, most notably in the Netherlands, China, Taiwan, Japan and Germany.

Based on our foreign currency exposure as of December 28, 2024, a 10.0% fluctuation could impact our financial position, results of operations or cash flows by $5.0 million to $6.0 million. Our attempts to hedge against these risks may not be successful and may result in a material adverse impact on our financial results and cash flow.

We enter into foreign exchange forward contracts to hedge a portion of our forecasted foreign currency-denominated expenses in the normal course of business and, accordingly, they are not speculative in nature. These instruments generally mature within twelve months. We have foreign exchange forward contracts with a notional amount of $42.5 million outstanding as of December 28, 2024.

Item 4. - CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our Management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 28, 2024. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of December 28, 2024, our disclosure controls and procedures were effective in providing reasonable assurance that the information required to be disclosed by us in reports filed under the Exchange Act of 1934 is (i) recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms; and (ii) accumulated and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding disclosure.

Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP.

In connection with the evaluation by our management, including with the participation of our Chief Executive Officer and Chief Financial Officer, of our internal control over financial reporting, no changes during the three months ended December 28, 2024 were identified to have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Additionally, and as previously announced on November 13, 2024, the Board of Directors authorized the New Program, with the intention that the New Program initiate upon the completion of the Prior Program. Contemporaneously, on December 2, 2024, the Company entered into a new written trading plan under Rule 10b5-1 of the Exchange Act, to facilitate repurchases under the New Program. The plan permits the purchase of up to approximately $300 million of the Company’s common stock from December 2, 2024 through December 2, 2029. The New Program may be suspended or discontinued at any time and is funded using the Company’s available cash, cash equivalents and short-term investments. Under the New Program, shares may be repurchased through open market and/or privately negotiated transactions at prices deemed appropriate by management. The timing and amount of repurchase transactions under the New Program depend on market conditions as well as corporate and regulatory considerations.

BASIS OF PRESENTATION	Dec. 28, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	1. BASIS OF PRESENTATION These consolidated condensed financial statements include the accounts of Kulicke and Soffa Industries, Inc. and its subsidiaries (“K&S,” “we,” “us,” “our,” or the “Company”), with appropriate elimination of intercompany balances and transactions. The interim consolidated condensed financial statements are unaudited and, in management’s opinion, include all adjustments (consisting only of normal and recurring adjustments) necessary for a fair statement of results for these interim periods. The interim consolidated condensed financial statements do not include all of the information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 28, 2024 (the “2024 Annual Report”) filed with the Securities and Exchange Commission on November 14, 2024, which includes the Consolidated Balance Sheets as of September 28, 2024 and September 30, 2023, and the related Consolidated Statements of Operations, Statements of Comprehensive Income, Changes in Shareholders’ Equity and Cash Flows for each of the years in the three-year period ended September 28, 2024. The results of operations for any interim period are not necessarily indicative of the results of operations for any other interim period or for a full year. Fiscal Year Each of the Company’s first three fiscal quarters end on the Saturday that is 13 weeks after the end of the immediately preceding fiscal quarter. The fourth quarter of each fiscal year ends on the Saturday closest to September 30. Fiscal 2025 quarters end on December 28, 2024, March 29, 2025, June 28, 2025 and October 4, 2025. In fiscal years consisting of 53 weeks, the fourth quarter will consist of 14 weeks. Fiscal 2024 quarters ended on December 30, 2023, March 30, 2024, June 29, 2024 and September 28, 2024. Nature of Business The Company designs, develops, manufactures and sells capital equipment and tools as well as services, maintains, repairs and upgrades equipment, all used to assemble semiconductor devices. The Company’s operating results depend upon the capital and operating expenditures of integrated device manufacturers (“IDMs”), outsourced semiconductor assembly and test providers (“OSATs”), foundry service providers, and other electronics manufacturers and automotive electronics suppliers worldwide which, in turn, depend on the current and anticipated market demand for semiconductors and products utilizing semiconductors. The semiconductor industry is highly volatile and experiences downturns and slowdowns which can have a severe negative effect on the semiconductor industry’s demand for semiconductor capital equipment, including assembly equipment manufactured and sold by the Company and, to a lesser extent, tools, solutions and services, including those sold or provided by the Company. These downturns and slowdowns have in the past adversely affected the Company’s operating results. The Company believes such volatility will continue to characterize the industry and the Company’s operations in the future. Use of Estimates The preparation of consolidated condensed financial statements requires management to make assumptions, estimates and judgments that affect the reported amounts of assets and liabilities, net revenue and expenses during the reporting periods, and disclosures of contingent assets and liabilities as of the date of the consolidated condensed financial statements. On an ongoing basis, management evaluates estimates, including but not limited to, those related to accounts receivable, reserves for excess and obsolete inventory and inventory valuation, carrying value and lives of fixed assets, goodwill and intangible assets, accrual for customer credit programs, the valuation estimates and assessment of impairment and observable price adjustments, income taxes, equity-based compensation expense, accrual for employee termination benefits and warranties. Management bases its estimates on historical experience and on various other assumptions believed to be reasonable. As a result, management makes judgments regarding the carrying values of the Company’s assets and liabilities that are not readily apparent from other sources. Authoritative pronouncements, historical experience and assumptions are used as the basis for making estimates, and on an ongoing basis, management evaluates these estimates. Actual results may differ from these estimates. In light of macroeconomic headwinds, there has been uncertainty and disruption in the global economy and financial markets. The Company is not aware of any specific event or circumstance that would require an update to its estimates or judgments or a revision of the carrying value of its assets or liabilities as of December 28, 2024. While there was no material impact from macroeconomic headwinds to our consolidated condensed financial statements as of and for the quarter ended December 28, 2024, these estimates may change, as new events occur and additional information is obtained, including factors related to these headwinds, that could materially impact our consolidated condensed financial statements in future reporting periods. Significant Accounting Policies There have been no material changes to our significant accounting policies summarized in Note 1: Basis of Presentation to our Consolidated Financial Statements included in our 2024 Annual Report. Recent Accounting Pronouncements Disclosure Improvements In October 2023, the Financial Accounting Standards Board (the "FASB") issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. This ASU aligns the requirements in the FASB Accounting Standards Codification with the SEC’s regulations. The amendments in the ASU are expected to clarify or improve disclosure and presentation requirements over a variety of Codification Topics. They will also allow users to more easily compare entities subject to the SEC’s existing disclosures with those entities that were not previously subject to the requirements, and align the requirements in the Codification with the SEC’s regulations. This ASU will become effective for each amendment on the date on which the SEC removes the related disclosure from its regulations. However, if by June 30, 2027, the SEC has not removed the related disclosure from its regulations, the amendments will be removed from the Codification and not become effective for any entity. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements. Segment Reporting In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosure, which aims to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. In addition, the amendments in the ASU enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The purpose of the amendments is to enable investors to better understand an entity's overall performance and assess potential future cash flows. This ASU will be effective for the Company's fiscal year 2025, and interim periods within the fiscal years beginning after the Company’s fiscal year 2026. Early adoption is permitted. The Company will include the required Segment Reporting disclosures within the Notes to Financial Statements with the filing of its Annual Report on Form 10-K for the year ending on October 4, 2025. Income Taxes In December 2023, the FASB issued ASU 2023-09 Income Taxes (Topic 740): Improvement to Income Tax Disclosures. The amendments in this update are intended to enhance the transparency and decision usefulness of income tax disclosures primarily through changes to the rate reconciliation and income taxes paid information. This ASU will be effective for the Company's fiscal year 2026. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. ASU 2023-09 should be applied on a prospective basis, but retrospective application is permitted. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements. Disaggregation of Income Statement Expenses In November 2024, the FASB issued ASU 2024-03 Income Statement - Reporting Comprehensive Income -Expense Disaggregation Disclosures (Topic 220): Disaggregation of Income Statement Expenses. This ASU requires disclosure of certain expenses in the notes to the financial statements. This ASU will be effective for the Company's fiscal 2028 on a prospective basis, with retrospective application permitted. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements.

FAIR VALUE MEASUREMENTS	Dec. 28, 2024
Fair Value Disclosures [Abstract]
FAIR VALUE MEASURMENTS	6. FAIR VALUE MEASUREMENTS Accounting standards establish three levels of inputs that may be used to measure fair value: quoted prices in active markets for identical assets or liabilities (referred to as Level 1), inputs other than Level 1 that are observable for the asset or liability either directly or indirectly (referred to as Level 2) and unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities (referred to as Level 3). Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis We measure certain financial assets and liabilities as described in Note 4 and 5 at fair value on a recurring basis. There were no transfers between fair value measurement levels during the three months ended December 28, 2024. Fair Value Measurements on a Nonrecurring Basis Our non-financial assets such as intangible assets and property, plant and equipment are carried at cost unless impairment is deemed to have occurred. Fair Value of Financial Instruments Amounts reported as accounts receivables, prepaid expenses and other current assets, accounts payable and accrued expenses approximate fair value.

As of December 28, 2024, the outstanding amount under this facility was $4.7 million. Credit Facilities On February 15, 2019, the Company entered into a Facility Letter and Overdraft Agreement (collectively, the “Facility Agreements”) with MUFG Bank, Ltd., Singapore Branch (the “Bank”). The Facility Agreements provide the Company and one of its subsidiaries with an overdraft facility of up to $150.0 million (the “Overdraft Facility”) for general corporate purposes. Amounts outstanding under the Overdraft Facility, including interest, are payable upon thirty days written demand by the Bank. Interest on the Overdraft Facility is calculated on a daily basis, and the applicable interest rate is calculated at the Secured Overnight Financing Rate (“SOFR”) plus a margin of 1.5% per annum. The Overdraft Facility is an unsecured facility per the terms of the Facility Agreements. The Facility Agreements contain customary non-financial covenants, including, without limitation, covenants that restrict the Company’s ability to sell or dispose of its assets, cease owning at least 51% of two of its subsidiaries (the “Subsidiaries”), or encumber its assets with material security interests (including any pledge of monies in the Subsidiaries' cash deposit account with the Bank). The Facility Agreements also contain typical events of default, including, without limitation, non-payment of financial obligations when due, cross defaults to other material indebtedness of the Company and any breach of a representation or warranty under the Facility Agreements. As of December 28, 2024, there were no outstanding amounts under the Overdraft Facility.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation	These consolidated condensed financial statements include the accounts of Kulicke and Soffa Industries, Inc. and its subsidiaries (“K&S,” “we,” “us,” “our,” or the “Company”), with appropriate elimination of intercompany balances and transactions. The interim consolidated condensed financial statements are unaudited and, in management’s opinion, include all adjustments (consisting only of normal and recurring adjustments) necessary for a fair statement of results for these interim periods. The interim consolidated condensed financial statements do not include all of the information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 28, 2024 (the “2024 Annual Report”) filed with the Securities and Exchange Commission on November 14, 2024, which includes the Consolidated Balance Sheets as of September 28, 2024 and September 30, 2023, and the related Consolidated Statements of Operations, Statements of Comprehensive Income, Changes in Shareholders’ Equity and Cash Flows for each of the years in the three-year period ended September 28, 2024. The results of operations for any interim period are not necessarily indicative of the results of operations for any other interim period or for a full year.
Fiscal Year	Fiscal Year Each of the Company’s first three fiscal quarters end on the Saturday that is 13 weeks after the end of the immediately preceding fiscal quarter. The fourth quarter of each fiscal year ends on the Saturday closest to September 30. Fiscal 2025 quarters end on December 28, 2024, March 29, 2025, June 28, 2025 and October 4, 2025. In fiscal years consisting of 53 weeks, the fourth quarter will consist of 14 weeks. Fiscal 2024 quarters ended on December 30, 2023, March 30, 2024, June 29, 2024 and September 28, 2024.
Nature of business	Nature of Business The Company designs, develops, manufactures and sells capital equipment and tools as well as services, maintains, repairs and upgrades equipment, all used to assemble semiconductor devices. The Company’s operating results depend upon the capital and operating expenditures of integrated device manufacturers (“IDMs”), outsourced semiconductor assembly and test providers (“OSATs”), foundry service providers, and other electronics manufacturers and automotive electronics suppliers worldwide which, in turn, depend on the current and anticipated market demand for semiconductors and products utilizing semiconductors. The semiconductor industry is highly volatile and experiences downturns and slowdowns which can have a severe negative effect on the semiconductor industry’s demand for semiconductor capital equipment, including assembly equipment manufactured and sold by the Company and, to a lesser extent, tools, solutions and services, including those sold or provided by the Company. These downturns and slowdowns have in the past adversely affected the Company’s operating results. The Company believes such volatility will continue to characterize the industry and the Company’s operations in the future.
Use of Estimates	Use of Estimates The preparation of consolidated condensed financial statements requires management to make assumptions, estimates and judgments that affect the reported amounts of assets and liabilities, net revenue and expenses during the reporting periods, and disclosures of contingent assets and liabilities as of the date of the consolidated condensed financial statements. On an ongoing basis, management evaluates estimates, including but not limited to, those related to accounts receivable, reserves for excess and obsolete inventory and inventory valuation, carrying value and lives of fixed assets, goodwill and intangible assets, accrual for customer credit programs, the valuation estimates and assessment of impairment and observable price adjustments, income taxes, equity-based compensation expense, accrual for employee termination benefits and warranties. Management bases its estimates on historical experience and on various other assumptions believed to be reasonable. As a result, management makes judgments regarding the carrying values of the Company’s assets and liabilities that are not readily apparent from other sources. Authoritative pronouncements, historical experience and assumptions are used as the basis for making estimates, and on an ongoing basis, management evaluates these estimates. Actual results may differ from these estimates. In light of macroeconomic headwinds, there has been uncertainty and disruption in the global economy and financial markets. The Company is not aware of any specific event or circumstance that would require an update to its estimates or judgments or a revision of the carrying value of its assets or liabilities as of December 28, 2024. While there was no material impact from macroeconomic headwinds to our consolidated condensed financial statements as of and for the quarter ended December 28, 2024, these estimates may change, as new events occur and additional information is obtained, including factors related to these headwinds, that could materially impact our consolidated condensed financial statements in future reporting periods.
Significant Accounting Policies	Significant Accounting Policies There have been no material changes to our significant accounting policies summarized in Note 1: Basis of Presentation to our Consolidated Financial Statements included in our 2024 Annual Report.
Recent accounting pronouncements	Recent Accounting Pronouncements Disclosure Improvements In October 2023, the Financial Accounting Standards Board (the "FASB") issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. This ASU aligns the requirements in the FASB Accounting Standards Codification with the SEC’s regulations. The amendments in the ASU are expected to clarify or improve disclosure and presentation requirements over a variety of Codification Topics. They will also allow users to more easily compare entities subject to the SEC’s existing disclosures with those entities that were not previously subject to the requirements, and align the requirements in the Codification with the SEC’s regulations. This ASU will become effective for each amendment on the date on which the SEC removes the related disclosure from its regulations. However, if by June 30, 2027, the SEC has not removed the related disclosure from its regulations, the amendments will be removed from the Codification and not become effective for any entity. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements. Segment Reporting In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosure, which aims to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. In addition, the amendments in the ASU enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The purpose of the amendments is to enable investors to better understand an entity's overall performance and assess potential future cash flows. This ASU will be effective for the Company's fiscal year 2025, and interim periods within the fiscal years beginning after the Company’s fiscal year 2026. Early adoption is permitted. The Company will include the required Segment Reporting disclosures within the Notes to Financial Statements with the filing of its Annual Report on Form 10-K for the year ending on October 4, 2025. Income Taxes In December 2023, the FASB issued ASU 2023-09 Income Taxes (Topic 740): Improvement to Income Tax Disclosures. The amendments in this update are intended to enhance the transparency and decision usefulness of income tax disclosures primarily through changes to the rate reconciliation and income taxes paid information. This ASU will be effective for the Company's fiscal year 2026. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. ASU 2023-09 should be applied on a prospective basis, but retrospective application is permitted. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements. Disaggregation of Income Statement Expenses In November 2024, the FASB issued ASU 2024-03 Income Statement - Reporting Comprehensive Income -Expense Disaggregation Disclosures (Topic 220): Disaggregation of Income Statement Expenses. This ASU requires disclosure of certain expenses in the notes to the financial statements. This ASU will be effective for the Company's fiscal 2028 on a prospective basis, with retrospective application permitted. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements.
