NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation — The unaudited Condensed Consolidated Financial Statements included in this quarterly report on Form 10-Q include the accounts of the Company and its majority-owned subsidiaries and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). This financial information reflects all adjustments which are, in the opinion of the Company, normal, recurring and necessary for the fair financial statement presentation for the dates and periods presented. Certain information and footnote disclosures normally included in our annual financial statements, prepared in accordance with GAAP, have been condensed or omitted from the interim financial statements in this Quarterly Report on Form 10-Q. Therefore, these unaudited financial statements should be read in conjunction with the Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended December 29, 2023.
Fiscal Year — The Company uses a 52-53 week fiscal year ending on the Friday nearest December 31. All references to quarters refer to fiscal quarters and all references to years refer to fiscal years.
Principles of Consolidation — The Company’s Condensed Consolidated Financial Statements include the accounts of the Company and its majority-owned subsidiaries and all intercompany accounts and transactions have been eliminated upon consolidation.
Significant Accounting Policies — There were no changes to the accounting policies disclosed in Note 1, Organization and Significant Accounting Polices of the Company’s Annual Report on Form 10-K for the year ended December 29, 2023 that had a material impact on the Company's condensed consolidated financial statements and related notes.
Accounting Standards Recently Adopted
The Company did not adopt any new accounting standards during the first quarter of fiscal year 2024 that had a significant impact on the Company’s condensed consolidated financial statements.
Accounting Standards Not Yet Adopted
In November 2023, FASB issued Accounting Standard Update (ASU) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires a public entity to disclose significant segment expenses and other segment items on an annual and interim basis and provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. The ASU does not change how a public entity identifies its operating segments, aggregates them, or applies the quantitative thresholds to determine its reportable segments. The Company is required to adopt this standard in the fiscal year 2024 for the annual reporting ending December 27, 2024, with retrospective disclosure of prior periods presented. The Company expects this ASU to only impact its disclosures with no impact to its results of operations, cash flows and financial condition.
In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which amends the guidance in ASC 740, Income Taxes. ASU No. 2023-09 is intended to improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in
- 9 -

the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. The Company is required to adopt this standard prospectively in fiscal year 2025 for the annual reporting period ending December 26, 2025. The Company is currently evaluating the potential impact of adopting this new guidance on its consolidated financial statements and related disclosures.
2. BUSINESS COMBINATIONS
On October 25, 2023, the Company acquired 100% of the shares of HIS Innovations Group (“HIS”), a privately held company based in Hillsboro, Oregon. HIS is a leading supplier to the semiconductor sub-fab segment including the design, manufacturing, and integration of components, process solutions, and fully integrated sub-systems. The acquisition strengthens the Company's leadership in developing and supplying critical products to the semiconductor industry, and extends our reach into the sub-fab area.
The purchase price of HIS for purposes of the Company’s preliminary purchase price allocation was determined to be $73.6 million, which includes initial cash consideration of $46.5 million and the fair value of potential earn-out payments of approximately $27.1 million. These potential earn-out payments represent up to $70.0 million of cash consideration that may be payable based on the financial performance of the acquired business during the fiscal years 2023, 2024, and 2025. The fair value of the potential earn-out payments was determined utilizing a Monte Carlo simulation model.
The Company has assigned the purchase price of HIS to the tangible assets, liabilities and identifiable intangible assets acquired, based on their estimated fair values. The excess of purchase price over the aggregate fair value was recorded as goodwill. Goodwill associated with the acquisition is primarily attributable to the future technology, market presence and knowledgeable and experienced workforce. The fair value assigned to identifiable intangible assets acquired was determined using the income approach taking into account the Company’s consideration of a number of inputs, including a third-party analysis that was based upon estimates and assumptions provided by the Company. These estimates and assumptions were determined through established and generally accepted valuation techniques and with the assistance of a valuation specialist.
The assigned purchase price is preliminary pending the completion of various analyses and the finalization of estimates. The primary areas of the purchase price that are not yet finalized relate to the measurement of working capital, acquired income tax related balances, and residual goodwill. During the measurement period, which can be no more than one year from the date of acquisition, we expect to continue to obtain information to assist us in determining the final fair value of the net assets acquired at the acquisition date. Assets acquired and liabilities assumed are recorded based on valuations derived from estimated fair value assessments and assumptions used by the Company. Thus, the provisional measurements of fair value discussed above are subject to change. The Company expects to finalize the valuation as soon as practicable, but not later than one year from the acquisition date. While the Company believes that its estimates and assumptions underlying the valuations are reasonable, different estimates and assumptions could result in different valuations assigned to the individual assets acquired, liabilities assumed, and the resulting amount of goodwill.
The following table summarizes the preliminary fair values of assets acquired and liabilities assumed at the date of acquisition:

4. FAIR VALUE
The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The following table summarizes, for assets or liabilities measured at fair value, the respective fair value and the classification by level of input within the fair value hierarchy:

The estimated fair value of foreign currency forward contracts is based upon quoted market prices obtained from independent pricing services for similar derivative contracts and these financial instruments are characterized as Level 2 assets in the fair value hierarchy.
- 12 -

The estimated fair value of pension obligation is based on expected years of service and average compensation. The valuation model used to value pension obligation utilizes mortality rate, inflation, interest rate risks and changes in the life expectancy for pensioners. These assumptions are routinely made in the appraisal process by the independent actuary resulting in a Level 3 classification. As of March 29, 2024, the Company's aggregate pension benefit obligations was $12.0 million and the fair value of the pension plan assets was $11.4 million. The underfunded pension benefit obligations was $0.6 million as of March 29, 2024. The Company recognizes the overfunded or underfunded status of defined benefit pension plans, measured as the difference between the fair value of the plan assets and the benefit obligation. Each overfunded plan is recognized as an asset and each underfunded plan is recognized as a liability.
The Company measures its contingent earn-out liabilities at fair value on a recurring basis using a Monte Carlo simulation model. The significant unobservable inputs used in the model include the forecasted operating profit of the acquired business during each of calendar years 2024 and 2025. Significant increases or decreases to the forecasted results would result in a significantly higher or lower liability, with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Ultimately, the liability will be equivalent to the amount paid, and the difference between the fair value estimate and amount paid will be recorded in earnings. The amount paid that is less than or equal to the contingent earn-out liability on the acquisition date is reflected as cash used in financing activities in the consolidated statements of cash flows. Any amount paid in excess of the contingent earn-out liability on the acquisition date will be reflected as cash used in operating activities in the consolidated statements of cash flows. For the three months ended March 29, 2024, the Company recorded $1.3 million of loss from change in the fair value of contingent earn-out related to the acquisition of HIS. This loss from change in the fair value was recognized as other income (expense), net in the Condensed Consolidated Statements of Operations.
There were no transfers from Level 1 or Level 2. Fair value adjustments were noncash, and therefore did not impact the Company’s liquidity or capital resources.
5. GOODWILL AND INTANGIBLE ASSETS
Goodwill
The Company’s methodology for allocating the purchase price relating to an acquisition is determined through established and generally accepted valuation techniques. Goodwill is measured as the excess of the consideration transferred over the sum of the amounts assigned to tangible and identifiable intangible assets acquired less liabilities assumed.
To test goodwill for impairment, the Company first performs a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If the Company concludes it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, the Company does not proceed to perform a quantitative impairment test. If the Company concludes it is more likely than not that the fair value of the reporting unit is less than its carrying value, a quantitative goodwill impairment test will be performed by comparing the fair value of each reporting unit to its carrying value. A quantitative impairment analysis, if necessary, considers the income approach, which requires estimates of the present value of expected future cash flows to determine a reporting unit’s fair value. Significant estimates include revenue growth rates and operating margins used to calculate projected future cash flows, discount rates, and future economic and market conditions. A goodwill impairment charge is recognized for the amount by which the reporting unit’s fair value is less than its carrying value. Any loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The process of evaluating the potential impairment of goodwill and intangible assets requires significant judgment. The Company regularly monitors current business conditions and other factors including, but not limited to, adverse industry or economic trends and lower projections of profitability that may impact future operating results.
During the three months ended March 29, 2024, there were no changes to the Company's reporting units, and the Company did not recognize any impairment charges or additions to goodwill. Details of aggregate goodwill of the Company are as follows:

Balance at March 29, 2024$191.7 $73.5 $265.2 
Intangible Assets
Intangible assets are generally recorded in connection with a business acquisition. The Company evaluates the useful lives of its intangible assets each reporting period to determine whether events and circumstances require revising the remaining period of amortization. In addition, the Company reviews finite-lived intangible assets for impairment whenever events or changes in circumstances indicate the carrying value may not be recoverable and evaluates indefinite-lived intangible asset for impairment annually, or more frequently if indicators of potential impairment exist. Management considers such
- 13 -

indicators as significant differences in product demand from the estimates, changes in the competitive and economic environment, technological advances, and changes in cost structure.

The Company amortizes its intangible assets on a straight-line or accelerated basis over the estimated economic life of the assets. Amortization expense was approximately $7.7 million and $5.8 million for the three months ended March 29, 2024 and March 31, 2023, respectively. Amortization expense related to recipes, standard operating procedures, developed technology and certain intellectual property/know-how is charged to cost of revenues and the remainder is charged to general and administrative expense. As of March 29, 2024, future estimated amortization expense is expected to be as follows:

6. BORROWING ARRANGEMENTS
The Company's Term Loan with Barclays Bank has a maturity date of August 27, 2025. The Company pays monthly interest payments in arrears and quarterly principal payments of 0.625% of the outstanding principal balance since March 31, 2021, with the remaining principal paid upon maturity.
The revolving credit facility has an available commitment of $150.0 million and a maturity date of February 27, 2025. The Company pays a quarterly commitment fee in arrears equal to 0.25% of the average daily available commitment outstanding. Outstanding letters of credit reduce the availability of the revolving credit facility and, as of March 29, 2024, the Company had $146.1 million, net of $3.9 million of outstanding letters of credit, available under this revolving credit facility.
The letter of credit facility has an available commitment of $50.0 million and a maturity date of February 27, 2025. The Company pays a quarterly fee in arrears equal to 2.5% (subject to certain adjustments to the Term Loan) of the dollar equivalent of all outstanding letters of credit, and a fronting fee equal to 0.125% of the undrawn and unexpired amount of each letter of credit. As of March 29, 2024, the Company had $3.9 million of outstanding letters of credit and $46.1 million of available commitments remaining under the letter of credit facility.
On June 29, 2023, the Company entered into a Fourth Amendment (the “Fourth Amendment”) to the Credit Agreement to replace the LIBOR-based reference interest rate option with a reference interest option based upon Term SOFR under the Credit Agreement.
- 14 -

Under the Credit Facilities, the Company may elect that the Term Loan bear interest at a rate per annum equal to either (a) “ABR” (as defined in the Credit Agreement), plus the applicable margin or (b) the “Eurodollar Rate” (as defined in the Credit Agreement), based on SOFR, plus the applicable margin. The applicable margin for the Term Loan is equal to a rate per annum to either (i) at any time that the Company’s corporate family rating is Ba3 (with a stable outlook) or higher from Moody’s and BB- (with a stable outlook) or higher from S&P, (x) 3.50% for such Eurodollar term loans and (y) 2.50% for such ABR term loans or (ii) at all other times, (x) 3.75% for such Eurodollar term loans and (y) 2.75% for such ABR term loans. Interest on the Term Loan is payable on (1) in the case of such ABR term loans, the last day of each calendar quarter and (2) in the case of such Eurodollar term loans, the last day of each relevant interest period and, in the case of any interest period longer than three months, on each successive date three months after the first day of such interest period.
At March 29, 2024, the Company had an outstanding amount under the Term Loan of $475.4 million, gross of unamortized debt issuance costs of $5.5 million. As of March 29, 2024, the interest rate on the outstanding Term Loan was 9.2%.
The Credit Agreement requires the Company to maintain certain financial covenants including a consolidated fixed charge coverage ratio (as defined in the Credit Agreement) as of the last day of any fiscal quarter of at least 1.25 to 1.00, and a consolidated leverage ratio (as defined in the Credit Agreement) as of the last day of any fiscal quarter of no greater than 3.75 to 1.00. On July 27, 2023, the Company entered into a Fifth Amendment (“Amended Credit Agreement”) which modified certain covenants described in the Amended Credit Agreement. This modification is applicable only to the revolving credit facility portion of its credit facilities. The Company currently has no revolving loans outstanding under the Credit Agreement. As of March 29, 2024, the Company was in compliance with the financial covenants contained within the Amended Credit Agreement.
The Company has a credit agreement with a local bank in the Czech Republic that provides for a revolving credit facility in the aggregate of up to 7.0 million euros (approximately $7.6 million). As of March 29, 2024, no debt was outstanding under this revolving credit facility.
Fluid Solutions has credit facilities with various financial institutions in Israel that provides borrowing up to $11.0 million. As of March 29, 2024, Fluid Solutions had a $5.3 million outstanding balance under these facilities with average interest rate ranges from 7.6% to 7.8%.
As of March 29, 2024, the Company’s total bank debt was $475.2 million, net of unamortized debt issuance costs of $5.5 million. As of March 29, 2024, the Company had $146.1 million, $5.7 million, and $7.6 million available to draw from its credit facilities in the U.S., Israel and Czech Republic, respectively.
The fair value of the Company’s long-term debt was based on Level 2 inputs, and fair value was determined using quoted prices for similar liabilities in inactive markets. The Company’s carrying value approximates fair value for the Company’s long-term debt.
7. INCOME TAX
The Company's effective tax rate was 366.7% and 89.7% for the three months ended March 29, 2024 and March 31, 2023, respectively. The Company’s income tax provision was $9.9 million and $3.5 million for the three months ended March 29, 2024 and March 31, 2023, respectively. The change in respective tax rates reflects, primarily, changes in the geographic mix of worldwide earnings and financial results in jurisdictions which are taxed at different rates and the impact of losses in jurisdictions with full federal and state valuation allowances. The increase also reflects the impact of the expiration of a reduced tax rate incentive on a portion of the Company's earnings in certain international subsidiaries and thus the Company is applying the local corporate statutory tax rate on those earnings. The Company is in the process of renewing the international tax incentive and when renewed will make an adjustment to its effective tax rate in that period. Company management continuously evaluates the need for a valuation allowance and, as of March 29, 2024, concluded that a full valuation allowance on its U.S. federal and state and certain of its foreign deferred tax assets was still appropriate.
As of March 29, 2024 and March 31, 2023, the Company’s gross liability for unrecognized tax benefits, excluding interest, was $2.9 million and $2.7 million, respectively. Increases or decreases to interest and penalties on uncertain tax positions are included in the income tax provision in the Condensed Consolidated Statements of Operations. Although it is possible that some of the unrecognized tax benefits could be settled within the next twelve months, the Company cannot reasonably estimate the outcome at this time.

8. RETIREMENT PLANS
Defined Benefit Plans
Cinos Korea has a noncontributory defined benefit pension plan covering substantially all of its employees upon their retirement. The Company's entities in Israel do have noncontributory defined benefit pension plans covering their employees upon their retirement. The benefits for these plans are based on expected years of service and average compensation. The net period costs are recognized as employees render the services necessary to earn the postretirement benefits. The Company records annual amounts relating to the pension plan based on calculations that incorporate various actuarial and other assumptions, including discount rates, mortality, assumed rates of return, compensation increases and turnover rates. The Company reviews its assumptions on an annual basis and makes modifications to the assumptions based on current and expected rates of return and trends when it is appropriate to do so. The effect of modifications to those assumptions is recorded in accumulated other comprehensive income and amortized to net periodic cost over future periods using the corridor method. The Company believes that the assumptions utilized in recording its obligations under the plans are reasonable based on its experience and market conditions.
As of March 29, 2024, the benefit obligation of the plans was $12.0 million and the fair value of the benefit plan assets was $11.4 million which are invested in several fixed deposit accounts with financial institutions. As of March 29, 2024, the underfunded balance of the plans of $0.6 million has been recorded by the Company and is included in other liabilities.
Amounts recognized in accumulated other comprehensive loss and contributed for the three months ended March 29, 2024 were negligible. During the three months ended March 31, 2023, the Company contributed $0.1 million and recognized $0.2 million in accumulated other comprehensive loss.
As of March 29, 2024, the Company's future estimated payment obligations for the respective fiscal years are as follows:
(In millions)

Employee Savings and Retirement Plan
The Company sponsors a 401(k) savings and retirement plan (the “401(k) Plan”) for all U.S. employees who meet certain eligibility requirements. Participants can elect to contribute to the 401(k) Plan, on a pre-tax basis, up to 25% of their salary to a maximum of the IRS limit. The Company matches 50.0% of each employee's contribution, up to a maximum of 6% of the employee's eligible earnings. The Company made $1.0 million and $0.9 million discretionary employer contributions to the 401(k) Plan for the three months ended March 29, 2024 and March 31, 2023, respectively.
9. COMMITMENTS AND CONTINGENCIES
Commitments
The Company leases real estate and equipment under various non-cancelable operating leases.
Contingencies
From time to time, the Company is subject to various legal proceedings and claims, either asserted or unasserted, that arise in the ordinary course of business. Although the outcome of the various legal proceedings and claims individually or in the aggregate cannot be predicted with certainty, the Company has not had a history of outcomes to date that have been material to the Condensed Consolidated Statements of Operations and does not believe that any of these proceedings or other claims will have a material adverse effect on its consolidated financial condition, results of operations or cash flows.

10. STOCKHOLDERS’ EQUITY AND NONCONTROLLING INTERESTS
Treasury Stock
On October 20, 2022, the Board of Directors approved a share repurchase program authorizing the Company to purchase up to an aggregate of $150 million of the Company’s common stock over a three-year period. No shares were repurchased under this program for the three months ended March 29, 2024.
The Company may reissue these treasury shares as part of its stock-based compensation programs.
Non-controlling Interests
The Company owns part of the outstanding shares of Cinos Korea, a South Korean company that provides outsourced cleaning and recycling of precision parts for the semiconductor industry through its operating facilities in South Korea and through a partial interest in Cinos China.
The carrying value of the remaining interest held by another shareholder in Cinos Korea and the remaining interest in Cinos China are presented as noncontrolling interests in the accompanying Condensed Consolidated Financial Statements. The noncontrolling interests were estimated based on the values of Cinos Korea and Cinos China on a 100% basis. The values were calculated based on the pro-rata portion of total Services earnings before interest expense, taxes, depreciation and amortization contributed by each entity.
11. EMPLOYEE STOCK PLANS
Employee Stock Plans
The Company grants stock awards in the form of restricted stock units (“RSUs”) and performance stock units (“PSUs”) to its employees as part of the Company’s long-term equity compensation plan. These stock awards are granted to employees with a unit purchase price of zero dollars and typically vest over three years, subject to the employee’s continued service with the Company and, in the case of PSUs, subject to achieving certain performance goals and market conditions. The Company also grants common stock to its board members in the form of restricted stock awards (“RSAs”), which vest on the earlier of the next Annual Shareholder Meeting, or 365 days from date of grant.
Stock-based compensation expense includes compensation costs related to estimated fair values of awards granted. The estimated fair value of the Company’s equity-based awards is amortized on a straight-line basis over the awards’ vesting period and is adjusted for performance as it relates to PSUs.
The following table shows the Company’s stock-based compensation expense included in the Condensed Consolidated Statements of Operations:

For the three months ended March 29, 2024, 24,000 RSUs were granted with a weighted average fair value of $44.21 per share. No RSU's were granted for the three months ended March 31, 2023.
No PSUs and RSA's were granted for the three months ended March 29, 2024 and March 31, 2023.

Vested and expected to vest restricted stock units and restricted stock awards1.2$56.0 
As of March 29, 2024, approximately $19.1 million of unrecognized stock-based compensation cost related to employee and director awards remains to be amortized on a straight-line basis over a weighted average period of 1.7 years, and will be adjusted for subsequent changes in future grants. The total unamortized expense of the Company’s unvested RSAs as of March 29, 2024 was $0.1 million.
Under the current PSU program, which was effective beginning fiscal 2021, performance goals are set at the time of grant and performance is reviewed at the end of a three-year period. The percentage to be applied to each participant’s target award ranges from zero to 200%, based upon the extent to which the financial performance goals are achieved. If specific performance threshold levels for the financial goals are met on an annual basis, the amount earned for that element will be applied to one-third of the participant’s PSU award granted to determine the number of total units earned.
Recipients of PSU awards generally must remain employed by the Company on a continuous basis through the end of the three-year performance period in order to receive any amount of the PSUs covered by that award. In events such as death, disability or retirement, the recipient may be entitled to pro-rata amounts of PSUs as defined in the Plan. Target shares subject to PSU awards do not have voting rights of common stock until earned and issued following the end of the three-year performance period.
Employee Stock Purchase Plan
The ESPP permits employees to purchase common stock at a discount through payroll withholdings at certain specified dates (purchase period) within a defined offering period. The purchase price is 85% of the fair market value of the common stock at the end of the purchase period and is intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code.
No shares were issued under the ESPP during the three months ended March 29, 2024 and March 31, 2023. The Company recorded $0.2 million of expense related to ESPP for the three months ended March 29, 2024. No ESPP related expense was recorded for the three months ended March 31, 2023.
12. REVENUE RECOGNITION
Revenue is recognized when the Company satisfies the performance obligations as evidenced by the transfer of control of the promised goods or services to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services.
The Company sells its products and services primarily to customers in the semiconductor capital equipment industry. The Company’s revenues are highly concentrated, and therefore highly dependent upon a small number of customers. Typical payment terms with our customers range from thirty to sixty days.
The Company’s Products business segment provides warranty on its products for a period of up to two years and provides for warranty costs at the time of sale based on historical activity. Determination of the warranty reserve requires the Company to make estimates of product return rates and expected costs to repair or replace the products under warranty. If actual return rates and/or repair and replacement costs differ significantly from these estimates, adjustments to recognize additional cost of revenues may be required in future periods. The warranty reserve is included in other current liabilities on the Condensed Consolidated Balance Sheets and is not considered significant.
The Company’s products are manufactured and services provided at the Company's locations throughout the Americas, Asia Pacific and Europe and the Middle East (“EMEA”). Sales to customers are initiated through a purchase order and are governed by our standard terms and conditions, written agreements, or both. Revenue is recognized when performance obligations under the terms of an agreement with a customer are satisfied; generally, this occurs with the transfer of control
- 18 -

of the products or when the Company provides the services. Based on the enforceable rights included in our agreements or prevailing terms and conditions, products produced by the Company without an alternative use are not protected by an enforceable right of payment that includes a reasonable profit throughout the duration of the agreement. Consignment sales are recognized in revenue at the earlier of the period that the goods are consumed or after a period of time subsequent to receipt by the customer as specified by terms of the agreement, provided control of the promised goods or services has transferred.
Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Sales, value-add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. Certain of our customers may receive cash-based incentives, such as rebates or credits, which are accounted for as variable consideration. We estimate these amounts based on the expected amount to be provided to customers and reduce revenues recognized. Accruals for unpaid customer rebates of $1.0 million and $2.0 million as of March 29, 2024 and December 29, 2023, respectively, were netted against accounts receivable. The Company's disaggregated revenues are apportioned by segments within the Company’s Condensed Consolidated Statement of Operations.
The Company’s principal markets include America, Asia Pacific and EMEA. The Company's foreign operations are conducted primarily through its subsidiaries in China, Malaysia, Singapore, Israel, Taiwan, South Korea, United Kingdom and the Czech Republic. Revenues by geographic area are categorized based on the customer’s location to which the products were shipped or services were performed. The following table sets forth revenue by geographic area:

15. REPORTABLE SEGMENTS
The Company prepares financial results based on three operating segments (Products, Services, and HIS) and two reportable segments (Products and Services). The Products and HIS operating segments have been aggregated into the Products reportable segment based upon consistency of economic characteristics, nature of products, similarity of production process, and class of customers. The Company’s Chief Executive Officer (chief operating decision maker) views and evaluates operations based on the results of each of the reportable segments. The following table describes each segment:

The Company uses segment profit or loss as the primary measure of profitability to evaluate operating performance and to allocate capital resources. Segment profit or loss is defined as a segment’s income or loss from continuing operations before other income and income taxes included in the accompanying Condensed Consolidated Statements of Operations.
Any intercompany sales and associated profit (and any other intercompany items) are eliminated from segment results. There were no significant intercompany eliminations for the periods presented.

Overview
Ultra Clean Holdings, Inc., (“UCT”, the “Company” or “We”) is a leading developer and supplier of critical subsystems, components, parts, and ultra-high purity cleaning and analytical services primarily for the semiconductor industry. UCT offers its customers an integrated outsourced solution for major subassemblies, improved design-to-delivery cycle times, design for manufacturability, prototyping and part and component manufacturing, as well as tool chamber parts cleaning and coating, and micro-contamination analytical services. We report results for two operating segments: Products and Services. Our Products segment primarily designs, engineers and manufactures production tools, components and parts, and modules and subsystems for the semiconductor and display capital equipment markets. Products include chemical delivery modules, frame assemblies, gas delivery systems, fluid delivery systems, precision robotics, process modules as well as other high-level assemblies. Our Services segment provides ultra-high purity parts cleaning, process tool part recoating, surface encapsulation and high sensitivity micro contamination analysis primarily for the semiconductor device makers and wafer fabrication equipment (“WFE”) markets.
We ship a majority of our products and provide most of our services to U.S. registered customers with locations both in and outside the U.S. In addition to U.S. manufacturing and service operations, we manufacture products and provide parts cleaning and other related services in our Asia Pacific, Europe and Middle East (“EMEA”) facilities to support local and U.S. based customers. We conduct our operating activities primarily through our subsidiaries.
Over the long term, we believe the semiconductor market we serve will continue to grow due to multi-year industry demand from a broad range of drivers, such as new processor architectures that enable higher performance servers necessary for cloud, artificial intelligence (“AI”) and machine learning applications. We also believe that semiconductor original equipment manufacturers (“OEM”) are increasingly relying on partners like UCT to fulfill their expanding capacity requirements. Additionally, our Services business is benefiting as device manufacturers rely on precision cleaning and coating to achieve ever more advanced devices.
Critical Accounting Estimates
Our Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States, which require us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses and related disclosure at the date of our Condensed Consolidated Financial Statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to inventories, income taxes, business combinations, contingent earn-out liabilities and goodwill, intangible assets and long-lived assets. We base our estimates and judgments on historical experience and on various other factors that we believe to be reasonable under the circumstances, the results of which form the basis of our judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. We consider certain accounting policies related to revenue recognition, inventory valuation, accounting for income taxes, business combinations, valuation of goodwill, intangible assets and long-lived assets to be critical policies due to the estimates and judgments involved in each.
- 22 -

There have been no significant changes to our critical accounting policies, significant judgments and estimates disclosed in our Annual Report on Form 10-K subsequent to December 29, 2023. For further information on our critical and other significant accounting policies and estimates, see Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our Annual Report on Form 10-K for the fiscal year ended December 29, 2023, as filed with the SEC.

Products revenues increased $49.9 million from the three months ended March 31, 2023 to the three months ended March 29, 2024. The increase in Products revenues was primarily due to an increase in customer demand, along with an overall market improvement in the semiconductor industry and in part due to the acquisition of HIS in October 2023.
Services revenues decreased $5.5 million from the three months ended March 31, 2023 to the three months ended March 29, 2024 , primarily due to decrease in demand across its customer base.

The increase was due to higher sales volumes driving increased material costs of $38.3 million.
Cost of Services revenues consists of direct labor, overhead and materials (such as chemicals, gases and consumables). Cost of Services revenues decreased $4.1 million for the three months ended March 29, 2024, respectively, compared to the same periods in the prior year, driven by lower volumes of service orders, resulting in decreased labor related costs (the largest component of Cost of Services) of $3.1 million.

Effective tax rate366.7 %89.7 %
The increase in the effective tax rate for the three months ended March 29, 2024 compared to the same period in the prior year is primarily attributable to changes in the geographic mix of worldwide earnings and financial results in jurisdictions which are taxed at different rates and the impact of losses in jurisdictions with full federal and state valuation allowances. The increase also reflects the impact of the expiration of a reduced tax rate incentive on a portion of our earnings in certain international subsidiaries and thus we are applying the local corporate statutory tax rate on those earnings. We are in the process of renewing the international tax incentive; when renewed will make an adjustment to its effective tax rate in that period.
Company management continuously evaluates the need for a valuation allowance on its deferred tax assets and, as of March 29, 2024, concluded that a full valuation allowance on its federal, state and certain of its foreign deferred tax assets remained appropriate.

Net decrease in cash and cash equivalents$(14.0)$(36.7)
Our primary cash inflows and outflows were as follows:
For the three months ended March 29, 2024, we generated cash from operating activities of $9.8 million compared to $28.0 million for the three months ended March 31, 2023. The $18.2 million decrease in net cash from operating activities was driven by a $16.4 million unfavorable change in net working capital and by a $7.6 million decrease in net income offset in part by a $5.8 million increase from non-cash items included in net income.
The major contributors in net changes in operating assets and liabilities for the three months ended March 29, 2024 were as follows:
Accounts receivable increased $13.7 million primarily due to the timing of shipments and collections and $13.6 million increase in inventories due to increased production levels.
Accounts payable increased $25.1 million, income taxes payable increased $2.1 million, and accrued compensation and related benefits decreased $10.6 million, primarily due to the timing of payments.
Net cash used in investing activities during the three months ended March 29, 2024 and March 31, 2023 consisted primarily of $18.0 million and $27.3 million purchases of property, plant and equipment, respectively.
During the three months ended March 29, 2024, cash used in financing activities was $4.5 million, compared to cash used in financing activities of $36.2 million in the three months ended March 31, 2023. When compared to
- 26 -

the same period in the prior year, the change in cash used in financing activities is due to $17.5 million higher principal payments on bank borrowings and to $14.2 million cash used in our share repurchase program.
We believe we have sufficient capital to fund our working capital needs, satisfy our debt obligations, maintain our existing capital equipment, purchase new capital equipment and make strategic acquisitions from time to time. As of March 29, 2024, we had cash and cash equivalents of $293.0 million compared to $307.0 million as of December 29, 2023. Our cash and cash equivalents, cash generated from operations, and amounts available under our revolving line of credit described below were our principal sources of liquidity as of March 29, 2024.
Fluid Solutions has an existing factoring arrangement with a financial institution in which a portion of its accounts receivable are sold on a non-recourse basis. As of March 29, 2024, Fluid Solutions factored $6.9 million under this arrangement.
We anticipate that our existing cash and cash equivalents balance and operating cash flow will be sufficient to service our indebtedness and meet our working capital requirements and technology development projects for at least the next twelve months. The adequacy of these resources to meet our liquidity needs beyond that period will depend on our growth, the size and number of any acquisitions, the state of the worldwide economy, our ability to meet our financial covenants with our credit facility, the cyclical expansion or contraction of the semiconductor capital equipment industry and the other industries we serve and capital expenditures required to meet possible increased demand for our products.
In order to expand our business or acquire additional complementary businesses or technologies, we may need to raise additional funds through equity or debt financing. If required, additional financing may not be available on terms that are favorable to us, if at all. If we raise additional funds through the issuance of equity or convertible debt securities, our stockholders’ equity interest will be diluted and these securities might have rights, preferences and privileges senior to those of our current stockholders. We may also require the consent of our new lenders to raise additional funds through equity or debt financing. No assurance can be given that additional financing will be available or that, if available, such financing can be obtained on terms favorable to our stockholders and us.
As of March 29, 2024, we have cash of approximately $204.0 million in our foreign subsidiaries. It is not practicable to determine the tax liability that might be incurred if the undistributed earnings of these foreign subsidiaries were to be distributed. For undistributed earnings of foreign subsidiaries which are not considered indefinitely reinvested, deferred taxes have been accrued.

Capital Expenditures
Capital expenditures were $18.0 million during the three months ended March 29, 2024 and were primarily attributable to the capital invested in our manufacturing facilities worldwide as well as costs associated with the ongoing design and implementation of our new enterprise resource planning system. The Company’s anticipated capital expenditures for the remainder of 2024 are expected to be financed primarily from our cash flow generated from operations and cash on hand.
Contractual Obligations
The Company had commitments to various third parties to purchase inventories totaling approximately $364.8 million as of March 29, 2024.
In conjunction with the sale of our products in the ordinary course of business, we provide standard indemnification against certain liabilities to our customers, which may include claims of losses by their own customers resulting out of property damages, bodily injuries or deaths, or infringement of intellectual property rights by our products. Our potential liability arising out of intellectual property infringement claims by any third party is generally uncapped. As of March 29, 2024, we have not incurred any significant costs to defend lawsuits or settle claims related to these indemnification arrangements. As a result, we believe the estimated fair value of these arrangements is minimal.

ITEM 3. Quantitative and Qualitative Disclosures About Market Risk
There were no significant changes to our quantitative and qualitative disclosures about market risk during the period covered by this report. Refer to Part II, Item 7A. “Quantitative and Qualitative Disclosures about Market Risk” included in our Annual Report on Form 10-K for our fiscal year ended December 29, 2023, for a more complete discussion of the market risks we encounter.
ITEM 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined in Rule 13a-15(e) under the Exchange Act. Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to management, including the chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure. Based upon this evaluation, our chief executive officer and our chief financial officer concluded the disclosure controls and procedures were not effective as of March 29, 2024, the end of the period covered by this Quarterly Report on Form 10-Q, due to material weaknesses in internal control over financial reporting described below.
Material Weaknesses in Internal Control Over Financial Reporting
As previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 29, 2023, the Company identified the following material weaknesses in our internal control over financial reporting that continue to exist as of March 29, 2024.
The Company did not design and maintain effective controls relating to the: (i) sufficiency of processes related to identifying and analyzing risks to the achievement of objectives across the entity, (ii) sufficiency of competent personnel to analyze risks of material misstatement and develop internal control activities to support the achievement of the Company’s internal control objectives; and (iii) monitoring of performance of control activities in accordance with established policies in a timely manner.
These material weaknesses contributed to the following additional material weaknesses:
(a) The Company did not design and maintain effective information technology (“IT”) general controls for certain information systems that are relevant to the preparation of its consolidated financial statements. Specifically, for certain of the Fluid Solutions operating subsidiaries in the Products segment which have not been migrated to the Company’s primary ERP system, the Company did not design and maintain (a) program change management controls to ensure that IT program and data changes affecting financial IT applications and underlying accounting records are identified, tested, authorized and implemented appropriately, and (b) user access controls to ensure appropriate segregation of duties that adequately restrict user and privileged access to our financial applications and data to appropriate company personnel. Business process controls that are dependent on information and data produced by systems affected by the deficiencies in IT general controls were deemed ineffective because they could have been adversely impacted.
(b) The Company did not design and maintain effective application controls over certain information technology systems that are relevant to the preparation of its consolidated financial statements. Specifically, for certain other international operating subsidiaries in the Products segment which have not been migrated to the Company’s primary ERP system, the Company did not design and maintain effective IT application controls or business process controls including, but not limited to appropriate segregation of duties. The business process controls were deemed ineffective because they could have allowed for certain personnel to have incompatible duties allowing for the creation, review, and processing of certain transactions without independent review and authorization which affects substantially all financial statement account balances and disclosures within such subsidiaries;
(c) The Company did not design and maintain effective controls to determine the valuation of inventories, including the write down of inventory to its estimated market value less costs to sell and the validation and approval of inventory costing;
(d) The Company did not design effective controls necessary to validate the accuracy of certain data used within the operation of controls which affects substantially all financial statement account balances and disclosures; and
(e) The Company did not design and maintain effective controls related to the review of cash flow forecasts used in the valuation of certain assets and liabilities acquired in a business combination. Specifically, the control activities related to
- 29 -

the review of the inputs and assumptions utilized to develop the cash flow forecasts used in the valuation of acquired intangible assets and contingent earn-out liabilities were not designed at an appropriate level of precision.
The material weaknesses described above did not result in any changes to previously released annual or interim financial results. However, these material weaknesses could result in misstatements of our consolidated financial statements that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected. Based on additional procedures and post-closing review, management concluded that the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q present fairly, in all material respects, our financial position, results of operations, and cash flows for the periods presented, in conformity with accounting principles generally accepted in the United States.
Remediation Plan
Management has been executing and remains committed to implementing measures designed to ensure that control deficiencies contributing to the material weaknesses are remediated, such that these controls are designed, implemented, and operating effectively. The following remediation actions are currently being implemented and are in progress:
engaging an external advisor to assist with evaluating and documenting the design and operating effectiveness of internal controls and assist with the remediation of deficiencies, as necessary;
hiring additional personnel to identify and analyze risks of material misstatement, develop internal control activities to support the achievement of the Company’s internal control objectives, and monitor the effective performance of those control objectives;
designing and implementing effective controls for certain operating subsidiaries not yet migrated to our primary ERP system, including controls over program changes and user access including segregation of duties;
designing and implementing effective controls over valuation of inventories and inventories costing;
designing and implementing effective controls over data used within the operation of controls; and
designing and implementing effective controls over the review of cash flow forecasts utilized in the valuation of acquired intangible assets and contingent earn-out liabilities in a business combination to ensure the accuracy of inputs and assumptions applied in the forecasting process.
As we continue to evaluate and work to improve our internal control over financial reporting, we may decide to take additional measures to address the material weaknesses or modify the remediation plans described above. We believe that these actions will remediate the material weaknesses, however the material weaknesses will not be considered remediated until the applicable controls have operated for a sufficient period of time, and management has concluded, through testing, that these controls are designed and operating effectively. While Management believes that the aforementioned plans will remediate the material weaknesses, there is no assurance on the exact timing of the completion of the remediation. As the remediation plans continue to be implemented, management may be required to take additional measures or modify the plan elements.
Changes in Internal Control Over Financial Reporting
There were no changes in internal control over financial reporting during the fiscal first quarter ended March 29, 2024, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
