Organization, Consolidation and Presentation of Financial Statements [Abstract]
Fiscal Year	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	Principles of Consolidation The Company’s 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.
Noncontrolling interests	Noncontrolling interests Noncontrolling interests are recognized to reflect the portion of equity in the Company’s consolidated subsidiaries that is not attributable, directly or indirectly, to the controlling stockholder. The Company’s consolidated entities include partially owned subsidiaries that provide outsourced cleaning and recycling of precision parts for the semiconductor industry through operating facilities in South Korea and China. The ownership interests held by other parties in these subsidiaries are presented as noncontrolling interests in the accompanying Consolidated Financial Statements. Net income (loss) attributable to noncontrolling interests is allocated based on the respective ownership interests and continues to be attributed even if such allocation results in a deficit noncontrolling interests balance.
Segments	Segments The Financial Accounting Standards Board’s (“FASB”) guidance regarding disclosure about segments in an enterprise and related information establishes standards for the reporting by public business enterprises of information about reportable segments, products and services, geographic areas, and major customers. The method for determining what information to report is based on the manner in which management organizes the reportable segments within the Company for making operational decisions and assessments of financial performance. The Company’s chief operating decision-maker is the Chief Executive Officer. The Company operates in two reportable segments: Products and Services.
Foreign Currency Translation and Remeasurement	Foreign Currency Translation and Remeasurement As of December 26, 2025, the functional currency of the Products business’ foreign subsidiaries is the U.S. Dollar except for the subsidiaries of Ham-Let (Israel-Canada) Ltd. (“Ham-Let” or “Fluid Solutions”) in the United Kingdom and Netherlands, which is the local currency. The functional currency of the Services division’s foreign subsidiaries is the local currency, except for that of its Singapore, Scotland and Ireland entities, which is the U.S. Dollar. For the Company’s foreign subsidiaries where the local currency is the functional currency, the Company translates the financial statements of these subsidiaries to U.S. Dollars using month-end exchange rates for assets and liabilities, and average exchange rates for revenue, costs and expenses. Translation gains and losses are recorded in accumulated other comprehensive income (loss) (“AOCI”) within UCT stockholders’ equity. For the Company’s foreign subsidiaries where the U.S. Dollar is the functional currency and functional currency differs from their local currency, any gains and losses resulting from the remeasurement of the assets and liabilities of these subsidiaries are recorded in other income (expense), net.
Use of Estimates	Use of Estimates The presentation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates and assumptions include, but not limited to, inventory valuation, accounting for income taxes, business combinations, contingent earn-out liabilities, valuation of goodwill, intangible assets and long-lived assets. The Company bases its estimates and judgments on historical experience and on various other assumptions that it believes are reasonable under the circumstances. However, future events are subject to change and the best estimates and judgments routinely require adjustments. Actual amounts may differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers currency on hand, demand deposits, time deposits, and all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash and cash equivalents. Cash and cash equivalents are held in various financial institutions in the United States and internationally.
Accounts Receivable	Accounts Receivable The majority of our accounts receivable are derived from sales to large multinational semiconductor capital equipment manufacturers throughout the world, are recorded at their invoiced amount, and do not bear interest.
Allowance for Expected Credit Losses	Allowance for Expected Credit Losses The Company maintains an allowance for expected losses resulting from the inability of its customers to make required payments. The Company evaluates its allowance for expected credit losses based on a combination of factors. In circumstances where specific invoices are deemed uncollectible, the Company provides a specific allowance against the amount due to reduce the net recognized receivable to the amount it reasonably believes will be collected. The Company also provides allowances based on its write-off history.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments which subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. The Company performs credit evaluations of its customers’ financial condition and generally requires no collateral. Cash is placed on deposit at large global financial institutions. Such deposits may be in excess of insured limits. Management believes that the financial institutions that hold the Company’s cash are creditworthy and, accordingly, minimal credit risk exists with respect to these balances.
Fair Value of Measurements	Fair Value of Measurements The Company measures its cash equivalents, derivative contracts, contingent earn-out liabilities and pension obligation at fair value on a recurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. Assets and liabilities recorded at fair value are measured and classified in accordance with a three-tier fair value hierarchy based on the observability of the inputs available in the market used to measure fair value: Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 — Inputs that are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant inputs are observable in the market or can be derived from observable market data. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including interest rate curves, foreign exchange rates, and credit ratings. Level 3 — Unobservable inputs that are supported by little or no market activities. The carrying values of cash and cash equivalents, accounts receivable, net, prepaid expenses and other current assets, accounts payable, accrued compensation and related benefits, and other current liabilities approximate their fair values due to their relatively short maturities as of December 26, 2025 and December 27, 2024.
Inventories	Inventories Inventories are stated at the lower of cost (which approximates actual cost on a first-in, first-out basis) or net realizable value. The Company evaluates the valuation of all inventories, including raw materials, work-in-process, finished goods and spare parts on a periodic basis. Obsolete inventory or inventory in excess of management’s estimated usage is written down to its estimated market value less costs to sell, if less than its cost. Inherent in the estimates of market value are management’s estimates related to economic trends and future demand for the Company’s products. Inventory write downs inherently involve judgments based on assumptions about expected future demand and the impact of market conditions on those assumptions. Although the Company believes that the assumptions it used in estimating inventory write downs are reasonable, significant changes in any one of the assumptions in the future could produce a significantly different result. There can be no assurances that future events and changing market conditions will not result in significant increases in inventory write downs.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are stated at cost, or, in the case of equipment under finance leases, the present value of future minimum lease payments at inception of the related lease. The Company also capitalizes interest on borrowings related to eligible capital expenditures. Direct costs incurred to develop software for internal use are capitalized. Costs related to the design or maintenance of internal use software are expensed as incurred. Depreciation expense is computed using the straight-line method over the estimated useful lives of assets. Leasehold improvements are depreciated over the shorter of the estimated useful lives or the term of the lease. The estimated useful life of an asset is reassessed whenever applicable facts and circumstances indicate a change in the estimated useful life of such asset has occurred.
Long-lived Assets	Long-lived Assets The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate the carrying value of an asset group may not be recoverable. The Company assesses the fair value of the assets based on the amount of the undiscounted future cash flows that the assets are expected to generate and recognizes an impairment loss when estimated undiscounted future cash flows expected to result from the use of the asset are less than the carrying value of the asset. If the Company identifies an impairment, the Company reduces the carrying value of the group of assets to comparable market values, when available and appropriate, or to its estimated fair value based on a discounted cash flow approach. At the end of fiscal years 2025, 2024 and 2023, the Company assessed the carrying value of its long-lived assets, including property, plant and equipment as well as its intangible assets and concluded that no impairment was required.
Leases	Leases The Company determines if an arrangement is a lease, or contains a lease, at the inception of the arrangement and reassesses that conclusion if the arrangement is modified. When the Company determines the arrangement is a lease, or contains a lease, at lease inception, it then determines whether the lease is an operating lease or a finance lease. Operating and finance leases with lease terms of greater than one year result in the Company recording a right-of-use (“ROU”) asset and lease liability on its balance sheet. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Operating and finance lease ROU assets and liabilities are initially recognized based on the present value of lease payments over the lease term. In determining the present value of lease payments, the Company uses the implicit interest rate if readily determinable or when the implicit interest rate is not readily determinable, the Company uses its incremental borrowing rate. The incremental borrowing rate is not a commonly quoted rate and is derived through a combination of inputs including the Company’s credit rating and the impact of full collateralization. The incremental borrowing rate is based on the Company’s collateralized borrowing capabilities over a similar term of the lease payments. The Company utilizes the incremental borrowing rate based on bank loan rates at the respective locations for leases where appropriate and the consolidated group bank loan rate where the Company does not have local bank financings. The operating lease ROU asset also includes any lease payments made in advance and is reduced by any lease incentives. Specific lease terms used in computing the ROU assets and lease liabilities may include options to extend or terminate the lease when the Company believes it is reasonably certain that it will exercise that option. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term. The Company has elected not to recognize ROU assets and lease liabilities that arise from short-term (12 months or less) leases for any class of underlying asset. Operating leases are included in operating lease ROU assets and in operating lease liabilities on the Company’s consolidated balance sheet.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill and indefinite-lived intangible assets are not amortized but are reviewed for impairment annually or more frequently if indicators of potential impairment exist. Finite-lived intangible assets are presented at cost, net of accumulated amortization, and are amortized on either a straight-line method or on an accelerated method over their estimated economic lives. The Company reviews goodwill and purchased intangible assets with indefinite lives for impairment annually in the fourth fiscal quarter and whenever events or changes in circumstances indicate that the carrying value exceeds their fair value, such as when reductions in demand or significant economic slowdowns in the semiconductor industry are present.
Deferred Debt Issuance Costs	Deferred Debt Issuance Costs Debt issuance costs incurred in connection with obtaining debt financing are deferred and presented as a direct deduction from Bank Borrowings in the accompanying Consolidated Balance Sheets. Deferred costs are amortized on an effective interest method basis over the contractual term.
Defined Benefit Plan	Defined Benefit Pension Plan The Company has several noncontributory defined benefit pension plans covering substantially all of the employees of two of its foreign entities upon termination of their employee services. 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 gain (loss) 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 plan are reasonable based on its experience and market conditions.
Revenue Recognition	Revenue Recognition Revenue is recognized when the Company satisfies 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 performs the following five steps to determine when to recognize revenue: (1) identification of the contract(s) with its customers, (2) identification of the performance obligations in the contract, (3) determination of the transaction price, (4) allocation of the transaction price to the performance obligations in the contract, and (5) recognition of revenue when, or as, a performance obligation is satisfied. For further discussion of the Company’s revenue recognition see Note 12 of Notes to the Consolidated Financial Statements. Shipping and Handling Costs Shipping and handling costs are included as a component of cost of revenues.
Research and Development Costs	Research and Development Costs Research and development costs are expensed as incurred.
Stock-Based Compensation Expense	Stock-Based Compensation Expense The Company maintains stock-based compensation plans which allow for the issuance of equity-based awards to directors and certain employees. These equity-based awards include restricted stock awards (“RSAs”), performance stock units (“PSUs”) and restricted stock units (“RSUs”). The RSAs and RSUs use the closing price of stock price on the day preceding the grant date as a proxy for fair value and compensation expense. The PSUs contain market conditions, and compensation expense is measured using a Monte Carlo simulation model and recognized over the requisite service period based on the expected market performance as of the grant date. Forfeitures are recognized as they occur. The Company also maintains an employee stock purchase plan (“ESPP”) that provides for the issuance of shares to all eligible employees of the Company at a discounted price.
Government Subsidies	Government Subsidies Government subsidies are recognized where there is reasonable assurance that the subsidy will be received and all attached conditions will be complied with. When the subsidy relates to an expense item, it is recognized as a reduction of that expense on a systematic basis over the periods that the related costs, for which it is intended to compensate, are expensed. When the subsidy relates to an asset, it is recognized as income in equal amounts over the expected useful life of the related asset. When the subsidy does not relate to specific expenses or assets, the income is accounted for in the period where there is reasonable assurance that the subsidy will be received.
Income Taxes	Income Taxes The Company utilizes the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the basis differences reverse. Deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, which will result in taxable or deductible amounts in the future. In evaluating our ability to realize our deferred tax assets within the jurisdiction from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations. In projecting future taxable income, we begin with historical results and incorporate assumptions about the amount of future federal, state, and foreign pretax operating income adjusted for items that do not have tax consequences. The assumptions about future taxable income require significant judgment and are consistent with the plans and estimates we are using to manage the underlying businesses. In evaluating the objective evidence that historical results provide, we consider recent cumulative income (loss). A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized. Income tax positions must meet a more likely than not recognition threshold to be recognized. The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits within the consolidated statements of income as income tax expense. The Company accounts for Global Intangible Low-Taxed Income as period costs when incurred.
Net Income (Loss) per Share	Net Income (Loss) per Share Basic net income per share is computed by dividing net income by the weighted average number of shares outstanding for the period. Diluted net income per share is calculated by dividing net income by the weighted average number of common shares outstanding and common equivalent shares from dilutive restricted stock using the treasury stock method, except when such shares are anti-dilutive. Under the treasury stock method, the assumed proceeds include the average unrecognized compensation expense of in-the-money stock options and restricted stock units. This results in the assumed buyback of additional shares, thereby reducing the dilutive impact of equity awards.
Business Combinations	Business Combinations The Company recognizes assets acquired (including goodwill and identifiable intangible assets), liabilities assumed and noncontrolling interest at fair value on the acquisition date. Subsequent changes to the fair value of such assets acquired and liabilities assumed are recognized in earnings, after the expiration of the measurement period, a period not to exceed 12 months from the acquisition date. Acquisition-related expenses and acquisition-related restructuring costs are recognized in earnings in the period in which they are incurred.
Accounting Standards Recently Adopted and Accounting Standards Not Yet Adopted	Accounting Standards Recently Adopted In December 2023, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU No. 2023-09”). ASU No. 2023-09 enhances the transparency and usefulness of income tax disclosures by requiring consistent categories and greater disaggregation in the rate reconciliation, as well as disaggregation of income taxes paid by jurisdiction. The ASU also includes other amendments aimed at improving the effectiveness of income tax disclosures. The Company adopted ASU 2023-09 for the year ended December 26, 2025, and applied the new disclosure requirements prospectively to the current annual period. Prior period disclosures have not been adjusted to reflect the new disclosure requirements. Accounting Standards Not Yet Adopted In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU No. 2024-03”) which requires entities to provide disaggregated disclosure of certain expense categories within relevant income statement captions, including, but not limited to, inventory purchases, employee compensation, depreciation, amortization, and depletion. In January 2025, the FASB issued ASU No. 2025-01, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date (“ASU No. 2025-01”), which confirmed that the guidance in ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The guidance is required to be applied prospectively, although retrospective application is permitted. The Company is currently evaluating the impact of ASU 2024-03 and ASU 2025-01 on its financial statement disclosures. In July 2025, the FASB issued ASU No. 2025-05, Financial Instruments - Credit Losses (Subtopic 326-20): Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU No. 2025-05”). The amendments in this update provide a practical expedient related to the estimation of expected credit losses for current accounts receivable and current contract assets that arise from transactions accounted for under FASB ASC 606. The standard should be applied prospectively, and is effective for annual periods, including interim reporting periods, beginning after December 15, 2025, with early adoption permitted. The Company does not expect it to have material effect on its consolidated financial statements and related disclosures. In September 2025, the FASB issued ASU No. 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (“ASU No. 2025-06”). The amendments in this update provide targeted improvements to the accounting for internal-use software costs by removing the concept of “project stages,” introducing a new capitalization threshold based on when management authorizes and commits to funding the project, and requiring that capitalization only occur when completion of the software is probable. The ASU also introduces the concept of “significant development uncertainty,” under which capitalization should cease until such uncertainty is resolved. Additionally, the amendments relocate the guidance for website development costs from ASC 350-50 to ASC 350-40 and require expanded disclosures for capitalized internal-use software costs consistent with those for long-lived assets under ASC 360-10. Entities may apply the guidance prospectively, retrospectively, or using a modified retrospective approach, with early adoption permitted. ASU 2025-06 is effective for annual periods beginning after December 15, 2027, and interim periods within those fiscal years. The Company is currently evaluating the impact of this guidance on its consolidated financial statements and related disclosures. In December 2025, the FASB issued ASU No. 2025-10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities (“ASU 2025-10”). ASU 2025-10 establishes authoritative guidance on the accounting for government grants received by business entities, including recognition, measurement, presentation, and disclosure requirements. Under the new guidance, a government grant should not be recognized until it is probable that the entity will both (i) comply with the conditions attached to the grant and (ii) receive the grant. The ASU distinguishes between (a) grants related to assets and (b) grants related to income, and requires entities to apply either a deferred-income approach or a cost-accumulation approach for grants related to assets. Grants related to income are to be recognized in earnings on a systematic and rational basis over the periods in which the entity recognizes the related costs. ASU 2025-10 also provides guidance on the accounting for forgivable loans, nonmonetary government grants, and repayments of previously recognized grants. For public business entities, ASU 2025-10 is effective for annual reporting periods beginning after December 15, 2028, and interim periods within those fiscal years. Early adoption is permitted. The standard permits modified prospective, modified retrospective, or full retrospective adoption approaches. The Company is currently evaluating the impact of ASU 2025-10 on its consolidated financial statements and related disclosures. In December 2025, the FASB issued ASU No. 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements (“ASU 2025-11”). ASU 2025-11 provides enhancements and clarifications to the existing interim reporting framework in Topic 270. The amendments establish a comprehensive listing of required interim disclosures, clarify the applicability of interim reporting guidance, and improve navigability and consistency in interim reporting. The ASU also introduces a new disclosure principle that requires entities to disclose events occurring after the end of the most recent annual period that have a material impact on the entity. Additionally, the amendments clarify the types of interim financial statements subject to GAAP (including condensed statements) and provide presentation and content requirements for interim periods. ASU 2025-11 is effective for interim periods within fiscal years beginning after December 15, 2027, for public business entities and after December 15, 2028, for all other entities. Early adoption is permitted, and it may be applied prospectively or retrospectively to prior periods presented. The Company is currently evaluating the impact of ASU 2025-11 on its consolidated financial statement disclosures. In December 2025, the FASB issued ASU No. 2025-12, Codification Improvements (“ASU No. 2025-12”), which addresses stakeholder feedback and makes incremental improvements to U.S. GAAP. The amendments clarify, correct errors, and make minor improvements to the Accounting Standards Codification to enhance understandability and application. ASU 2025-12 is effective for fiscal years beginning after December 15, 2026, including interim periods within those fiscal years. The Company will adopt this guidance in fiscal 2027 and does not expect the adoption to have a material impact on its consolidated financial position, results of operations, or disclosures.
Accounts Receivable Factoring Agreements	Accounts Receivable Factoring Agreements The Company has receivables factoring arrangements, pursuant to which certain receivables are sold to banks without recourse in exchange for cash. Transactions under the receivables factoring arrangements are accounted for as sales under ASC 860, Transfers and Servicing of Financial Assets, with the sold receivables removed from the Company’s balance sheet. Under these receivables factoring arrangements, the Company does not maintain any beneficial interest in the receivables sold. The banks’ purchase of eligible receivables is subject to a maximum amount of uncollected receivables. The Company services the receivables on behalf of the banks, but otherwise maintains no significant continuing involvement with respect to the receivables. Sale proceeds that are representative of the fair value of factored receivables, less a factoring fee, are reflected in cash flows from operating activities on the Consolidated Statements of Cash Flows. The Company did not receive any sale proceeds in excess of the fair value of factored receivables during the periods presented.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

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 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.

Noncontrolling interests

Noncontrolling interests are recognized to reflect the portion of equity in the Company’s consolidated subsidiaries that is not attributable, directly or indirectly, to the controlling stockholder. The Company’s consolidated entities include partially owned subsidiaries that provide outsourced cleaning and recycling of precision parts for the semiconductor industry through operating facilities in South Korea and China. The ownership interests held by other parties in these subsidiaries are presented as noncontrolling interests in the accompanying Consolidated Financial Statements. Net income (loss) attributable to noncontrolling interests is allocated based on the respective ownership interests and continues to be attributed even if such allocation results in a deficit noncontrolling interests balance.

Segments

The Financial Accounting Standards Board’s (“FASB”) guidance regarding disclosure about segments in an enterprise and related information establishes standards for the reporting by public business enterprises of information about reportable segments, products and services, geographic areas, and major customers. The method for determining what information to report is based on the manner in which management organizes the reportable segments within the Company for making operational decisions and assessments of financial performance. The Company’s chief operating decision-maker is the Chief Executive Officer. The Company operates in two reportable segments: Products and Services.

Foreign Currency Translation and Remeasurement

As of December 26, 2025, the functional currency of the Products business’ foreign subsidiaries is the U.S. Dollar except for the subsidiaries of Ham-Let (Israel-Canada) Ltd. (“Ham-Let” or “Fluid Solutions”) in the United Kingdom and Netherlands, which is the local currency. The functional currency of the Services division’s foreign subsidiaries is the local currency, except for that of its Singapore, Scotland and Ireland entities, which is the U.S. Dollar.

For the Company’s foreign subsidiaries where the local currency is the functional currency, the Company translates the financial statements of these subsidiaries to U.S. Dollars using month-end exchange rates for assets and liabilities, and average exchange rates for revenue, costs and expenses. Translation gains and losses are recorded in accumulated other comprehensive income (loss) (“AOCI”) within UCT stockholders’ equity. For the Company’s foreign subsidiaries where

the U.S. Dollar is the functional currency and functional currency differs from their local currency, any gains and losses resulting from the remeasurement of the assets and liabilities of these subsidiaries are recorded in other income (expense), net.

Use of Estimates

The presentation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates and assumptions include, but not limited to, inventory valuation, accounting for income taxes, business combinations, contingent earn-out liabilities, valuation of goodwill, intangible assets and long-lived assets. The Company bases its estimates and judgments on historical experience and on various other assumptions that it believes are reasonable under the circumstances. However, future events are subject to change and the best estimates and judgments routinely require adjustments. Actual amounts may differ from those estimates.

Cash and Cash Equivalents

The Company considers currency on hand, demand deposits, time deposits, and all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash and cash equivalents. Cash and cash equivalents are held in various financial institutions in the United States and internationally.

Accounts Receivable

The majority of our accounts receivable are derived from sales to large multinational semiconductor capital equipment manufacturers throughout the world, are recorded at their invoiced amount, and do not bear interest.

Allowance for Expected Credit Losses

The Company maintains an allowance for expected losses resulting from the inability of its customers to make required payments. The Company evaluates its allowance for expected credit losses based on a combination of factors. In circumstances where specific invoices are deemed uncollectible, the Company provides a specific allowance against the amount due to reduce the net recognized receivable to the amount it reasonably believes will be collected. The Company also provides allowances based on its write-off history.

Concentration of Credit Risk

Financial instruments which subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. The Company performs credit evaluations of its customers’ financial condition and generally requires no collateral.

Cash is placed on deposit at large global financial institutions. Such deposits may be in excess of insured limits. Management believes that the financial institutions that hold the Company’s cash are creditworthy and, accordingly, minimal credit risk exists with respect to these balances.

Fair Value of Measurements

The Company measures its cash equivalents, derivative contracts, contingent earn-out liabilities and pension obligation at fair value on a recurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. Assets and liabilities recorded at fair value are measured and classified in accordance with a three-tier fair value hierarchy based on the observability of the inputs available in the market used to measure fair value:

Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 — Inputs that are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant inputs are observable in the market or can be derived from observable market data. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including interest rate curves, foreign exchange rates, and credit ratings.

Level 3 — Unobservable inputs that are supported by little or no market activities.

The carrying values of cash and cash equivalents, accounts receivable, net, prepaid expenses and other current assets, accounts payable, accrued compensation and related benefits, and other current liabilities approximate their fair values due to their relatively short maturities as of December 26, 2025 and December 27, 2024.

Inventories

Inventories are stated at the lower of cost (which approximates actual cost on a first-in, first-out basis) or net realizable value. The Company evaluates the valuation of all inventories, including raw materials, work-in-process, finished goods and spare parts on a periodic basis. Obsolete inventory or inventory in excess of management’s estimated usage is written down to its estimated market value less costs to sell, if less than its cost. Inherent in the estimates of market value are management’s estimates related to economic trends and future demand for the Company’s products.

Inventory write downs inherently involve judgments based on assumptions about expected future demand and the impact of market conditions on those assumptions. Although the Company believes that the assumptions it used in estimating inventory write downs are reasonable, significant changes in any one of the assumptions in the future could produce a significantly different result. There can be no assurances that future events and changing market conditions will not result in significant increases in inventory write downs.

Property, Plant and Equipment

Property, plant and equipment are stated at cost, or, in the case of equipment under finance leases, the present value of future minimum lease payments at inception of the related lease. The Company also capitalizes interest on borrowings related to eligible capital expenditures. Direct costs incurred to develop software for internal use are capitalized. Costs related to the design or maintenance of internal use software are expensed as incurred.

Depreciation expense is computed using the straight-line method over the estimated useful lives of assets. Leasehold improvements are depreciated over the shorter of the estimated useful lives or the term of the lease. The estimated useful life of an asset is reassessed whenever applicable facts and circumstances indicate a change in the estimated useful life of such asset has occurred.

Long-lived Assets

The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate the carrying value of an asset group may not be recoverable. The Company assesses the fair value of the assets based on the amount of the undiscounted future cash flows that the assets are expected to generate and recognizes an impairment loss when estimated undiscounted future cash flows expected to result from the use of the asset are less than the carrying value of the asset. If the Company identifies an impairment, the Company reduces the carrying value of the group of assets to comparable market values, when available and appropriate, or to its estimated fair value based on a discounted cash flow approach.

At the end of fiscal years 2025, 2024 and 2023, the Company assessed the carrying value of its long-lived assets, including property, plant and equipment as well as its intangible assets and concluded that no impairment was required.

Leases

The Company determines if an arrangement is a lease, or contains a lease, at the inception of the arrangement and reassesses that conclusion if the arrangement is modified. When the Company determines the arrangement is a lease, or contains a lease, at lease inception, it then determines whether the lease is an operating lease or a finance lease. Operating and finance leases with lease terms of greater than one year result in the Company recording a right-of-use (“ROU”) asset and lease liability on its balance sheet. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Operating and finance lease ROU assets and liabilities are initially recognized based on the present value of lease payments over the lease term. In determining the present value of lease payments, the Company uses the implicit interest rate if readily determinable or when the implicit interest rate is not readily determinable, the Company uses its incremental borrowing rate.

The incremental borrowing rate is not a commonly quoted rate and is derived through a combination of inputs including the Company’s credit rating and the impact of full collateralization. The incremental borrowing rate is based on the Company’s collateralized borrowing capabilities over a similar term of the lease payments. The Company utilizes the incremental borrowing rate based on bank loan rates at the respective locations for leases where appropriate and the consolidated group bank loan rate where the Company does not have local bank financings.

The operating lease ROU asset also includes any lease payments made in advance and is reduced by any lease incentives. Specific lease terms used in computing the ROU assets and lease liabilities may include options to extend or terminate the lease when the Company believes it is reasonably certain that it will exercise that option. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term. The Company has elected not to recognize ROU assets and lease liabilities that arise from short-term (12 months or less) leases for any class of underlying asset. Operating leases are included in operating lease ROU assets and in operating lease liabilities on the Company’s consolidated balance sheet.

Goodwill and Intangible Assets

Goodwill and indefinite-lived intangible assets are not amortized but are reviewed for impairment annually or more frequently if indicators of potential impairment exist. Finite-lived intangible assets are presented at cost, net of accumulated amortization, and are amortized on either a straight-line method or on an accelerated method over their estimated economic lives. The Company reviews goodwill and purchased intangible assets with indefinite lives for impairment annually in the fourth fiscal quarter and whenever events or changes in circumstances indicate that the carrying value exceeds their fair value, such as when reductions in demand or significant economic slowdowns in the semiconductor industry are present.

Deferred Debt Issuance Costs

Debt issuance costs incurred in connection with obtaining debt financing are deferred and presented as a direct deduction from Bank Borrowings in the accompanying Consolidated Balance Sheets. Deferred costs are amortized on an effective interest method basis over the contractual term.

Defined Benefit Plan

Defined Benefit Pension Plan

The Company has several noncontributory defined benefit pension plans covering substantially all of the employees of two of its foreign entities upon termination of their employee services. 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 gain (loss) 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 plan are reasonable based on its experience and market conditions.

Revenue Recognition

Revenue is recognized when the Company satisfies 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 performs the following five steps to determine when to recognize revenue: (1) identification of the contract(s) with its customers, (2) identification of the performance obligations in the contract, (3) determination of the transaction price, (4) allocation of the transaction price to the performance obligations in the contract, and (5) recognition of revenue when, or as, a performance obligation is satisfied. For further discussion of the Company’s revenue recognition see Note 12 of Notes to the Consolidated Financial Statements.

Shipping and Handling Costs

Shipping and handling costs are included as a component of cost of revenues.

Research and Development Costs

Research and development costs are expensed as incurred.

Stock-Based Compensation Expense

The Company maintains stock-based compensation plans which allow for the issuance of equity-based awards to directors and certain employees. These equity-based awards include restricted stock awards (“RSAs”), performance stock units (“PSUs”) and restricted stock units (“RSUs”). The RSAs and RSUs use the closing price of stock price on the day preceding the grant date as a proxy for fair value and compensation expense. The PSUs contain market conditions, and compensation expense is measured using a Monte Carlo simulation model and recognized over the requisite service period based on the expected market performance as of the grant date. Forfeitures are recognized as they occur.

The Company also maintains an employee stock purchase plan (“ESPP”) that provides for the issuance of shares to all eligible employees of the Company at a discounted price.

Government Subsidies

Government subsidies are recognized where there is reasonable assurance that the subsidy will be received and all attached conditions will be complied with. When the subsidy relates to an expense item, it is recognized as a reduction of that expense on a systematic basis over the periods that the related costs, for which it is intended to compensate, are expensed. When the subsidy relates to an asset, it is recognized as income in equal amounts over the expected useful life of the related asset. When the subsidy does not relate to specific expenses or assets, the income is accounted for in the period where there is reasonable assurance that the subsidy will be received.

Income Taxes

The Company utilizes the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the basis differences reverse. Deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, which will result in taxable or deductible amounts in the future. In evaluating our ability to realize our deferred tax assets within the jurisdiction from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations. In projecting future taxable income, we begin with historical results and incorporate assumptions about the amount of future federal, state, and foreign pretax operating income adjusted for items that do not have tax consequences. The assumptions about future taxable income require significant judgment and are consistent with the plans and estimates we are using to manage the underlying businesses. In evaluating the objective evidence that historical results provide, we consider recent cumulative income (loss). A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized.

Income tax positions must meet a more likely than not recognition threshold to be recognized. The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits within the consolidated statements of income as income tax expense.

The Company accounts for Global Intangible Low-Taxed Income as period costs when incurred.

Net Income (Loss) per Share

Basic net income per share is computed by dividing net income by the weighted average number of shares outstanding for the period. Diluted net income per share is calculated by dividing net income by the weighted average number of common shares outstanding and common equivalent shares from dilutive restricted stock using the treasury stock method, except when such shares are anti-dilutive. Under the treasury stock method, the assumed proceeds include the average unrecognized compensation expense of in-the-money stock options and restricted stock units. This results in the assumed buyback of additional shares, thereby reducing the dilutive impact of equity awards.

Business Combinations

The Company recognizes assets acquired (including goodwill and identifiable intangible assets), liabilities assumed and noncontrolling interest at fair value on the acquisition date. Subsequent changes to the fair value of such assets acquired and liabilities assumed are recognized in earnings, after the expiration of the measurement period, a period not to exceed 12 months from the acquisition date. Acquisition-related expenses and acquisition-related restructuring costs are recognized in earnings in the period in which they are incurred.

Accounting Standards Recently Adopted and Accounting Standards Not Yet Adopted

Accounting Standards Recently Adopted

In December 2023, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU No. 2023-09”). ASU No. 2023-09 enhances the transparency and usefulness of income tax disclosures by requiring consistent categories and greater disaggregation in the rate reconciliation, as well as disaggregation of income taxes paid by jurisdiction. The ASU also includes other amendments aimed at improving the effectiveness of income tax disclosures. The Company adopted ASU 2023-09 for the year ended December 26, 2025, and applied the new disclosure requirements prospectively to the current annual period. Prior period disclosures have not been adjusted to reflect the new disclosure requirements.

Accounting Standards Not Yet Adopted

In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU No. 2024-03”) which requires entities to provide disaggregated disclosure of certain expense categories within relevant income statement captions, including, but not limited to, inventory purchases, employee compensation, depreciation, amortization, and depletion. In January 2025, the FASB issued ASU No. 2025-01, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date (“ASU No. 2025-01”), which confirmed that the guidance in ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The guidance is required to be applied prospectively, although retrospective application is permitted. The Company is currently evaluating the impact of ASU 2024-03 and ASU 2025-01 on its financial statement disclosures.

In July 2025, the FASB issued ASU No. 2025-05, Financial Instruments - Credit Losses (Subtopic 326-20): Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU No. 2025-05”). The amendments in this update provide a practical expedient related to the estimation of expected credit losses for current accounts receivable and current contract assets that arise from transactions accounted for under FASB ASC 606. The standard should be applied prospectively, and is effective for annual periods, including interim reporting periods, beginning after December 15, 2025, with early adoption permitted. The Company does not expect it to have material effect on its consolidated financial statements and related disclosures.

In September 2025, the FASB issued ASU No. 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (“ASU No. 2025-06”). The amendments in this update provide targeted improvements to the accounting for internal-use software costs by removing the concept of “project stages,” introducing a new capitalization threshold based on when management authorizes and commits to funding the project, and requiring that capitalization only occur when completion of the software is probable. The ASU also introduces the concept of “significant development uncertainty,” under which capitalization should cease until such uncertainty is resolved. Additionally, the amendments relocate the guidance for website development costs from ASC 350-50 to ASC 350-40 and require expanded disclosures for capitalized internal-use software costs consistent with those for long-lived assets under ASC 360-10. Entities may apply the guidance prospectively, retrospectively, or using a modified retrospective approach, with early adoption permitted. ASU 2025-06 is effective for annual periods beginning after December 15, 2027, and interim periods within those fiscal years. The Company is currently evaluating the impact of this guidance on its consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU No. 2025-10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities (“ASU 2025-10”). ASU 2025-10 establishes authoritative guidance on the accounting for government grants received by business entities, including recognition, measurement, presentation, and disclosure requirements. Under the new guidance, a government grant should not be recognized until it is probable that the entity will both (i) comply with the conditions attached to the grant and (ii) receive the grant. The ASU distinguishes between (a) grants related to assets and (b) grants related to income, and requires entities to apply either a deferred-income approach or a cost-accumulation approach for grants related to assets. Grants related to income are to be recognized in

earnings on a systematic and rational basis over the periods in which the entity recognizes the related costs. ASU 2025-10 also provides guidance on the accounting for forgivable loans, nonmonetary government grants, and repayments of previously recognized grants. For public business entities, ASU 2025-10 is effective for annual reporting periods beginning after December 15, 2028, and interim periods within those fiscal years. Early adoption is permitted. The standard permits modified prospective, modified retrospective, or full retrospective adoption approaches. The Company is currently evaluating the impact of ASU 2025-10 on its consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU No. 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements (“ASU 2025-11”). ASU 2025-11 provides enhancements and clarifications to the existing interim reporting framework in Topic 270. The amendments establish a comprehensive listing of required interim disclosures, clarify the applicability of interim reporting guidance, and improve navigability and consistency in interim reporting. The ASU also introduces a new disclosure principle that requires entities to disclose events occurring after the end of the most recent annual period that have a material impact on the entity. Additionally, the amendments clarify the types of interim financial statements subject to GAAP (including condensed statements) and provide presentation and content requirements for interim periods. ASU 2025-11 is effective for interim periods within fiscal years beginning after December 15, 2027, for public business entities and after December 15, 2028, for all other entities. Early adoption is permitted, and it may be applied prospectively or retrospectively to prior periods presented. The Company is currently evaluating the impact of ASU 2025-11 on its consolidated financial statement disclosures.

In December 2025, the FASB issued ASU No. 2025-12, Codification Improvements (“ASU No. 2025-12”), which addresses stakeholder feedback and makes incremental improvements to U.S. GAAP. The amendments clarify, correct errors, and make minor improvements to the Accounting Standards Codification to enhance understandability and application. ASU 2025-12 is effective for fiscal years beginning after December 15, 2026, including interim periods within those fiscal years. The Company will adopt this guidance in fiscal 2027 and does not expect the adoption to have a material impact on its consolidated financial position, results of operations, or disclosures.

Accounts Receivable Factoring Agreements

The Company has receivables factoring arrangements, pursuant to which certain receivables are sold to banks without recourse in exchange for cash. Transactions under the receivables factoring arrangements are accounted for as sales under ASC 860, Transfers and Servicing of Financial Assets, with the sold receivables removed from the Company’s balance sheet. Under these receivables factoring arrangements, the Company does not maintain any beneficial interest in the receivables sold. The banks’ purchase of eligible receivables is subject to a maximum amount of uncollected receivables. The Company services the receivables on behalf of the banks, but otherwise maintains no significant continuing involvement with respect to the receivables. Sale proceeds that are representative of the fair value of factored receivables, less a factoring fee, are reflected in cash flows from operating activities on the Consolidated Statements of Cash Flows. The Company did not receive any sale proceeds in excess of the fair value of factored receivables during the periods presented.
