The Company’s Products business 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. The Company’s Services business 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 ~~markets~~.

~~On March 31,~~markets. In 2021, the Company completed the acquisition of Ham-Let (Israel-Canada) Ltd. (“Ham-Let” or “Fluid Solutions”), ~~a public company organized under the laws of the State of~~ Israel (not a U.S. registrant), pursuant to an Agreement and Plan of Merger (the “Merger Agreement”), for approximately $362.9 million, which included $273.5 million of equity value plus $91.3 million of net debt offset by the settlement of an existing relationship of $1.9 million. Ham-LetFluid Solutions engages in the development, manufacturing and marketing of ~~process~~innovative control valves, fittings, and hoses for the control and monitoring of industrial systems in a variety of markets, including the Semiconductor market. These products are primarily used in ultra clean gas ~~transportation~~delivery systems as well as other systems for the transmission of liquids and gases. The Company’s primary reason for this acquisition was to broaden UCT’s relevance to the semiconductor equipment market and provide access to a new set of customers in the semiconductor fab infrastructure market. See Note 2 to the Company’s Condensed Consolidated Financial Statements for further information about the acquisition of Ham-Let.

On April 13, 2021, the Company completed an underwritten public offering of 3,181,818 shares of the Company’s common stock, in which the Company received net proceeds of approximately $167.6 million, after deducting the underwriting discounts and offering expenses payable by the Company. On April 29, 2021, the Underwriters exercised the option to purchase an additional 477,272 shares of the Company’s common stock for approximately $25.2 million in cash. The Company intends to use the net proceeds from this offering for general corporate purposes, which may include working capital, sales and marketing activities, product development, general and administrative matters, and capital expenditures. The Company may use a portion of the net proceeds to acquire complementary businesses, products, services, or technologies, although it has no agreements, commitments, or plans for any specific acquisitions at this time.

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.

Foreign Currency Translation and Remeasurement — The functional currency of the ~~majority~~Products business’s foreign subsidiaries, excluding the subsidiaries of ~~the Products division’s foreign subsidiaries~~Ham-Let, is the U.S. ~~dollar.~~Dollar. The functional currency of the ~~Service~~Ham-Let subsidiaries in Singapore, United Kingdom, Norway, Taiwan, South Korea and China, is their local currency, except for Israel, which is the U.S. Dollar. The functional currency of the Services division’s foreign subsidiaries is the local currency except for that of its Singapore and Scotland 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 ~~(AOCI)~~("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 ~~translation~~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 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, 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.

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 sells its products and provides services primarily to semiconductor capital equipment manufacturers in the United States. The Company performs credit evaluations of its customers’ financial condition and generally requires no collateral.

The Company’s most significant customers (having individually accounted for 10% or more of revenues) and their related revenues as a percentage of total revenues were as follows:


	Three Months Ended						Nine Months Ended						Three Months Ended
	September 24,			September 25,			September 24,			September 25,			April 1,			March 26,

NaN customers’ accounts receivable balances, Lam Research Corporation and Applied Materials, Inc., were individually greater than 10% of accounts receivable as of ~~September 24,~~April 1, 2022 and as of December 31, 2021,, and in the aggregate approximately ~~34.8% of accounts receivable.~~ ~~NaN~~43.1 ~~of the Company’s customers account receivable balances, Lam Research Corporation, Applied Materials, Inc.~~% and ~~ASM International, Inc., were individually greater than 10.0%~~39.0% of total accounts receivable, ~~as of December 25, 2020, and in the aggregate approximately 67.3% of total accounts receivable.~~respectively.

Fair Value of Measurements — The Company measures its cash equivalents, derivative contracts, contingent earn-out liabilities, pension obligation and common stock purchase obligation at(prior to the reclass to non-controlling interests) 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.

~~- 10 -~~

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

- 9 -

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.

Derivative Financial Instruments — The Company uses forward contracts to hedge a portion of, but not all, existing and anticipated foreign currency denominated transactions typically expected to occur within 24 months. The purpose of the hedge is to mitigate the effect of exchange rate fluctuations on certain foreign currency denominated costs and eventual cash flows. The Company recognizes derivative instruments as either assets or liabilities in the accompanying Condensed Consolidated Balance Sheets at fair value. The Company records changes in the fair value of the derivatives in the accompanying Condensed Consolidated Statements of Operations as other income (expense), net, or as a component of AOCI in the accompanying Condensed Consolidated Balance Sheets.

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 ~~products, and technological obsolescence of~~ 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 ~~net~~ — 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. Capitalized interest is added to the cost of the qualified assets and is subject to depreciation. Depreciation and amortization are computed using the straight-line method over the lesser of the estimated useful lives of the assets or the terms of the leases. Useful lives range from three to fifty years. Direct costs incurred to develop software for internal use are capitalized and amortized over an estimated useful life of three to ten years. Costs related to the design or maintenance of internal use software are expensed as incurred. Capitalized internal use software is included in computer equipment and software.

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.

The Company assessed the useful lives of its long-lived assets, including property, plant and equipment as well as its intangible assets as of ~~September 24, 2021~~April 1, 2022 and concluded that 0 impairment was required.

Leases — The Company determines if an arrangement is a lease, or contains a lease, at the inception of the ~~arrangement.~~arrangement and reassess 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 ~~or greater~~ result in the Company recording a right-of-use ~~(ROU)~~("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 ~~consolidated group~~ incremental borrowing rate based on bank loan rates at the respective locations for ~~all leases.~~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 prior to the adoption of ASC 842 and excludes 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. As allowed by the guidance, 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, other current liabilities, and long-term operating lease liabilities on the Company’s consolidated balance sheet. The Company’s finance leases at ~~September 24, 2021~~April 1, 2022 and December ~~25, 2020~~31, 2021 were not significant.

- 1110 -

Goodwill and Indefinite-Lived Intangible Assets — Goodwill and indefinite-lived intangible assets are not amortized, but are reviewed for impairment annually. 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 future discounted cash flows. The Company reviews goodwill and purchased intangible assets with indefinite lives for impairment annually and whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable, 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 Condensed Consolidated Balance Sheets. Deferred costs are amortized on an effective interest method basis over the contractual term.

Defined Benefit Pension Plan — The ~~Company~~Company has aseveral noncontributory defined benefit pension ~~plan covering~~plans covering substantially all of the employees of ~~one~~three 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 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 plan are reasonable based on its experience and market conditions. For further discussion of the Company’s defined benefit pension plan see Note 98 of the Notes to the Condensed Consolidated Financial Statements.

Revenue Recognition — Revenue is recognized when we satisfy performance obligations as evidenced by the transfer of control of the promised goods or services ~~is transferred~~ 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.

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 ~~executives~~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 derived service period based on the expected market performance ~~stock units (“PSUs”).~~as of the grant date. 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. See Note 11 for further discussion.

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 income 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.

- 11 -

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 (“GILTI”) as period costs when incurred.

Net Income 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

~~- 12 -~~

common shares outstanding and common equivalent shares from dilutive restricted stock using the treasury stock method, except when such shares are anti-dilutive. ~~See Note 15 of the Notes to the Condensed Consolidated Financial Statements.~~

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 Standard Not Yet Adopted

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financing Reporting. This guidance provides temporary optional expedients and exceptions through December 31, 2022 to the U.S. GAAP guidance on contract modifications to ease the financial reporting burdens of the expected market transition from the London Interbank Offered Rate ~~(LIBOR)~~("LIBOR") and other interbank offered rates to alternative reference rates. The Company expects to adopt this guidance and apply it to reference rate reform effected arrangement modifications.The Company does not expect this new standard to have a material effect on its Condensed Consolidated Financial Statements.

Although there are several other new accounting pronouncements issued by the FASB, the Company does not believe any of these accounting pronouncements had or will have a material impact on its Condensed Consolidated Financial Statements.

2. BUSINESS COMBINATIONS

Ham-Let (Israel-Canada) Ltd.

On March 31, 2021, the Company acquired all of the outstanding common shares of Ham-Let (Israel-Canada) Ltd. ("Ham-let") for a total purchase consideration of ~~$362.9~~$362.9 million which included $273.5 million of equity value plus $91.3 million of net debt offset by the settlement of an existing relationship of $1.9 million (vendor of UCT). In addition, the Company incurred approximately $10.6 million of costs related to the acquisition ($1.0 million incurredpaid in fiscal year 2020 and $9.6 million was charged to operations for the nine months ended September 24, 2021). Ham-Let engages in the development, manufacturing and marketing of process valves, fittings and hoses for the control and monitoring of industrial systems in a variety of markets, including the Semiconductor market. These products are primarily used in ultra clean gas transportation systems for the transmission of liquids and gases. The Company’s primary reason for this acquisition was to broaden UCT’s relevance to the semiconductor equipment market and provide access to a new set of customers in the semiconductor fab infrastructure market.cash. The Company borrowed an additional ~~$355.0~~$355.0 million from its existing ~~Credit Facility~~credit facility to finance the acquisition. See further discussion in Note 76 to the Notes to Condensed Consolidated Financial Statements.

In December 2020, the Company announced the acquisition of Ham-Let. The expected cash consideration for the equity valuation at that time was approximately 934.7 million Israeli New Shekel (“ILS”) or $287.1 million in equity value. In order to hedge against the foreign currency fluctuation of the USD against ILS at the settlement date, UCT received Board of Director approval to enter into forward hedge contracts to buy ILS. In January 2021, UCT completed the purchase of forward hedge contracts of 905.8 million ILS to lock in the $283.9 million cash that was delivered at the closing of the Ham-Let acquisition.$287.1 million. US GAAP requires the recording of the purchase price of the acquired entity at the spot rate on acquisition date, rather than the cash amount hedged and paid. ~~The variance between the cash paid of $283.9 million and the spot value at acquisition of $273.5 million was a~~A loss of ~~$10.4~~$10.4 million ~~and~~on the forward hedge contract was recorded in the accompanying Condensed Consolidated Statements of Operations as other income (expense), net for the ~~nine~~three month period ended ~~September 24,~~March 26, 2021.

~~The~~During the first quarter of fiscal year 2022, the Company ~~has preliminarily allocated~~completed its analysis of its worldwide tax position and recorded a reduction in tax liabilities that resulted in a decrease to goodwill of approximately $1.5 million. In the ~~purchase price~~first quarter of ~~Ham-Let to~~fiscal year 2022, the tangible assets, liabilities, identifiable intangible assets acquired and noncontrolling interest, based on their estimated fair values. The excess of purchase price over the aggregate fair value was recorded as goodwill. Goodwill associated withCompany completed 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 an independent 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. The estimated fair value of the tangible and intangible assets acquired was allocated at Ham-Let’s acquisition date.

~~The allocation of the purchase price is preliminary pending the completion of various analyses~~accounting and the ~~finalization of estimates. The primary areas of the preliminary purchase price allocation that are not yet finalized relate to the fair values of~~ certain tangible assets and liabilities, primarily inventories, accounts receivable, property, plant and equipment, operating lease right-of-use assets and related operating lease liabilities, income and other taxes, intangible assets 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 during the measurement period. Assets acquired, liabilities assumed and noncontrolling interest 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

~~- 13 -~~

~~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 noncontrolling interest, and the resulting amount of goodwill.

~~Subsequent to the filing of the Company’s June 25, 2021 financial statements, the Company continued its analysis~~ of the fair value of the assets acquired and the liabilities ~~assumed~~assumed. The acquisition accounting for Ham-Let is final. None of the goodwill recorded as ~~well as the noncontrolling interests from~~part of the acquisition date through the end of the third quarter of 2021. As a result of its analysis, the Company recorded, as a measurement period adjustment, a reduction in the fair value of the inventories of approximately $6.6 million and an increase to noncontrolling interest of $0.6 million during the third quarter of 2021. This also resulted in an $0.8 million decrease in deferredwill be deductible for income tax ~~liabilities and an increase in goodwill of $6.4 million during the third quarter of 2021.~~purposes.

For~~ the three and nine months ended September 24, 2021, net sales of approximately $64.4 million and $122.6 million, respectively, attributable to Ham-Let were included in the consolidated results of operations. For the three and nine months ended September 24, 2021, results of operations included charges of $4.6 million and $9.2 million, respectively, attributable to amortization of purchased intangible assets. In addition, deal costs associated with the acquisition of $0.1 million and $9.5 million were included in the results of operations for the three and nine months ended September 24, 2021, respectively. Deal costs are included in general and administrative expenses in the Company’s Condensedacquisition.

The following unaudited pro forma consolidated results of operations assume the acquisition was completed as of the beginning of the earliest year of the reporting periods presented.

On April 15, 2019, the Company purchased substantially all of the assets of DMS, a semiconductor weldment and solutions provider based in Austin, Texas. Pursuant to the purchase agreement, the former owners of DMS were entitled to receive up to $12.5 million of potential cash earn-out if the combined weldment business, after the acquisition, achieved certain gross profit and gross margin targets for the twelve months ending June 26, 2020. During the second quarter of fiscal year 2020, DMS achieved the specified performance target of the earn-out, which resulted in the maximum payment of $12.5 million paid in August 2020. ~~In the first quarter of fiscal year 2020, the Company completed the acquisition accounting and the valuation of the fair value of the assets acquired and the liabilities assumed~~.

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:

-owned subsidiary of Ham-Let owns 70.0% interest in Rovac with an option to acquire the remaining 30.0% ownership interest. The fair value of the purchase option recorded in the Company’s financial statements was determined using the Black Scholes option pricing model which utilizes the stock price of Rovac, volatility, expected life and risk-free interest rate based on the implied yield available on U.S. Treasury Securities with a maturity equivalent to the purchase option’s expected life. These assumptions were developed during the valuation process resulting in a Level 3 classification.

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.

The estimated fair value of the pension obligation is based on expected years of service and average compensation. The valuation model used to value the 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 thus resulted in a Level 3 classification.

~~The~~ ~~estimated~~ fair value of the common stock purchase obligation is based on a combination of an income and market valuation approach. The income and market valuation approaches may incorporate Level 3 fair value measures for instances when observable inputs are not available. The more significant judgmental assumptions used to estimate the value of the common stock purchase obligation include an estimated discount rate, a range of assumptions that form the basis of the expected future net cash flows (e.g., the revenue growth rates and operating margins), and a company specific beta. The significant judgmental assumptions used that incorporate market data, including the relative weighting of market observable information and the comparability of that information in the valuation models, are forward-looking and could be affected by future economic and market conditions. In July 2021, the Company entered into an amendment with Cinos Korea and a shareholder of Cinos Korea to terminate the obligation to purchase additional interest in Cinos Korea. As a result, the balance of the common stock purchase obligation of $16.4 million was reclassified to the noncontrolling interest in Cinos Korea.

~~The Company~~ ~~utilizes foreign currency forward contracts to reduce the risk that its cash flows and earnings will be adversely affected by foreign currency exchange rate fluctuations~~. The Company classifies its foreign currency forward within Level 2 of the fair-value hierarchy discussed in Note 4 of the Company’s Condensed Consolidated Financial Statements as the valuation inputs are based on quoted prices and market observable data of similar instruments.

The Company uses foreign currency contracts to economically hedge the functional currency equivalent cash flows of non-U.S. dollar- denominated acquisitions. The change in fair value of these derivatives is recorded through earnings in other income (expense), net.

The Company records all derivatives in the Condensed Consolidated Balance Sheets at fair value. The Company’s accounting treatment for these derivative instruments is based on its hedge designation. The following tables show the Company’s derivative instruments at gross fair value as of September 24, 2021and December 25, 2020.

~~The effect of derivative instruments in cash flow hedging relationships on income and other comprehensive income (OCI) is summarized below:~~

The amount of gain or loss reclassified from accumulated OCI into income is $0.1 million and $0.2 million for the three and nine months ended September 24, 2021, respectively. The amount of gain or loss reclassified from accumulated OCI into income is not significant for the three and nine months ended September 25, 2020.

~~In 2020, the Company entered into multiple foreign currency contracts to hedge the functional currency equivalent cash flows related to the non-U.S. dollar-denominated acquisition price of~~ ~~Ham-Let~~5. As of March 26, 2021, these contracts were terminated and the $10.4 million liability related to these forward hedge contracts was paid on March 31, 2021 in conjunction with the acquisition of Ham-Let.

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.

~~- 18 -~~

Goodwill and purchased intangible assets with indefinite useful lives are not amortized, but are reviewed for impairment at least annually and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable.

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.

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 indefinite lived intangible assets for impairment when events or changes in circumstances indicate their carrying value may not be recoverable and tests definite lived intangible assets at least annually for impairment. Management considers such indicators as significant differences in product demand from the estimates, changes in the competitive and economic environment, technological advances, and changes in cost structure.

Details of intangible assets were as follows:

7.6. BORROWING ARRANGEMENTS

InOn August27, 2018, the Company entered into a credit agreement ~~(the “Credit Agreement”)~~ with Barclays Bank that provided a ~~Term Loan,~~term loan B, a ~~Revolving Credit Facility,~~revolving credit facility and a ~~Letter~~letter of ~~Credit Facility~~credit facility (collectively, the “Credit ~~Facility”~~Facilities”). UCT and certain of its subsidiaries have agreed to secure all of their ~~obligations~~obligations under the Credit ~~Facility~~Facilities by granting a first priority lien in substantially all of their respective personal property assets (subject to certain exceptions and limitations). ~~In August 2018, the~~The Company borrowed ~~$350.0~~$350.0 million under the ~~Term Loan Facility~~term loan and used the proceeds, together with cash on hand, to finance the acquisition of ~~QGT~~Quantum Global Technologies, LLC’s ("QGT") and to refinance its previous credit facilities.

On March 31, 2021, the Company entered into a Second Amendment (the “Second Amendment”), to the ~~Credit Agreement~~credit agreement dated as of August 27, 2018 and amended as of October 1, 2018 (as amended by the Second Amendment, the "Credit Agreement") to, among other things, (i) refinance and reprice ~~$272.8~~$272.8 million of existing term B borrowings that will remain outstanding and (ii) obtain a ~~$355.0~~$355.0 million senior secured incremental term loan B facility ((i) and (ii) collectively the “Term Loan”) with Barclays Bank, which increased the amount of term loan indebtedness outstanding under the Company’s Credit ~~Facility.~~Facilities.

The Term Loan has a maturity date of August 27, 2025, with monthly interest payments in arrears, quarterly principal payments of ~~0.625%~~0.625% of the outstanding principal balance ~~thereof~~ as of March 31, 2021, with the remaining principal paid upon ~~maturity.~~ maturity. Under the Credit ~~Facility,~~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 LIBOR, 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%~~3.50% for such Eurodollar term loans and (y) ~~2.50%~~2.50% for such ABR term loans or (ii) at all other times, (x) ~~3.75%~~3.75% for such Eurodollar term loans and (y) ~~2.75%~~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. On March 29, 2021, the Company elected that the Term Loan outstanding as of March 31, 2021 accrue interest based on the “Eurodollar Rate” for an initial interest period of one month. ~~As of March 31, 2021, the applicable margin with respect to the Term Loan facility was 3.75%.~~ Pursuant to the Second Amendment to the Credit Agreement, the Credit ~~Facility~~Facilities contains customary LIBOR replacement provisions in the event LIBOR is discontinued. At ~~September 24, 2021~~,April 1, 2022, the Company had an outstanding amount under the Term Loan of ~~$569.9~~$555.1 million, gross of unamortized debt issuance costs of ~~$14.4~~$12.4 million. As of ~~September 24, 2021~~,April 1, 2022, the interest rate on the outstanding Term Loan was ~~3.8%~~4.2%.

The ~~Revolving Credit Facility~~revolving credit facility has an initial available commitment of ~~$65.0~~$65.0 million and a maturity date of August 27, ~~2023.~~2023. The Company pays a quarterly commitment fee in arrears equal to ~~0.25%~~0.25% of the average daily available commitment outstanding.

~~The Revolving Credit Facility requires~~ Outstanding letters of credit reduce the availability of the revolving credit facility and, as of April 1, 2022, the Company ~~to maintain certain financial covenants, as defined in the Credit Agreement, including a consolidated fixed charge coverage ratio as~~had $62.2 million, net of ~~the last day~~$2.8 million of ~~any fiscal quarter~~outstanding letters of ~~at least 1.25 to 1.00, and a consolidated leverage ratio as~~credit available under this revolving credit facility.

In 2020, Cinos China amended its existing credit agreement ~~and entered into two additional credit agreements~~ with a local bank that provide ~~revolving credit facilities for~~ a ~~total available commitment~~term loan of ~~$3.5~~RMB 10.0 million (approximately $1.5 million) with ~~various~~a maturity ~~dates through~~ date of September 23, 2022 and an interest ~~rates ranging from 2.0% to 4.2%~~rate of 4.1%. As of ~~September 24, 2021,~~April 1, 2022, Cinos China ~~had outstanding debt~~had an amount of ~~$2.5~~RMB 8.5 million ~~with an average interest rate of 3.4%~~(approximately $1.3 million) outstanding under ~~these~~this credit ~~agreements.~~facility.

Cinos Korea has a credit agreement that provides a revolving credit facility for ~~a total~~ available commitment of 0.6 billion Korean Won (approximately ~~$0.5~~$0.5 million) with annual renewals ~~beginning~~in June ~~2022 with~~and an interest rate of ~~2.9%~~2.9%. ~~During the nine months ended September 25, 2020, borrowings under the revolving credit facility were insignificant and~~ There is 0 ~~debt was~~ balance outstanding as of ~~September 24, 2021.~~April 1, 2022.

~~UCT Fluid Delivery Solutions s.r.o.~~FDS 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 ~~6.0~~5.0 million ~~euros.~~euros (approximately $5.5 million). As of ~~September 24, 2021~~,April 1, 2022, no debt was outstanding under this revolving credit facility.

Ham-Let has credit facilities and loan agreements with various financial institutions. As of ~~September 24, 2021,~~April 1, 2022, Ham-Let had ~~$10.3~~$6.4 million of outstanding debt with interest rates ranging from ~~1.8%~~2.0% to ~~4.6%~~4.3%.

As of ~~September 24, 2021,~~April 1, 2022, the Company’s total bank debt was ~~$568.3~~$562.8 million, net of unamortized debt issuance costs of ~~$14.4~~$12.4 million. As of ~~September 24, 2021,~~April 1, 2022, the Company had ~~$65.0~~$62.2 million, ~~$9.7~~$5.5 million and ~~$1.0~~$0.5 million available ~~to borrow on~~draw from its revolving credit facilities in the U.S., Czech Republic and ~~China,~~South Korea, 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.

8.7. INCOME TAX

The Company's effective tax rate was ~~19.8%~~21.6% and ~~16.0%~~21.5% for the three months ended ~~September 24,~~April 1, 2022 and March 26, 2021, ~~and September 25, 2020, respectively, and 21.8% and 20.6% for the nine months ended September 24, 2021 and September 25, 2020.~~ respectively. The Company’s income tax provision was ~~$8.4~~$8.5 million and ~~$4.8~~$7.0 million for the three months ended ~~September 24,~~April 1, 2022 and March 26, 2021, ~~and September 25, 2020, respectively, and $21.6 and $15.0 for the nine months ended September 24, 2021 and September 25, 2020.~~respectively. The change in respective 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.

Company management continuously evaluates the need for a valuation allowance and, as of ~~September 24, 2021,~~April 1, 2022, concluded that a full valuation allowance on its U.S. federal and state and certain of its foreign deferred tax assets was still appropriate.

The Company provides for U.S. income taxes on the earnings of its foreign subsidiaries to the extent required by the Tax Cuts and Jobs Act (TCJA). In a prior period, the Company has also recognized a deferred tax liability for taxes that would be withheld on a distribution of a portion of the undistributed earnings of one of its China subsidiaries. However, the Company has not provided for withholding taxes on the remaining portion of the undistributed earnings of its China subsidiary nor for the undistributed earnings of its other foreign subsidiaries that it intends to reinvest indefinitely outside the U.S. The Company has also historically remitted earnings from its Singapore subsidiary to the U.S. and may do so again in the future. However, the Company has not provided for withholding taxes on undistributed Singapore earnings as Singapore does not currently impose a withholding tax on dividends. If the Company changes its intent to reinvest its undistributed foreign earnings indefinitely or if a greater amount of undistributed earnings is needed than the previous anticipated remaining unremitted foreign earnings, the Company could be required to accrue or pay foreign taxes on some or all of these undistributed earnings. As of ~~September 24,~~April 1, 2022 and March 26, 2021, the Company had undistributed earnings of foreign subsidiaries that are considered indefinitely invested outside of the U.S. of approximately $361.4 million. It is not practicable to determine the tax liability that might be incurred if these earnings were to be distributed.

~~As of~~ ~~September 24, 2021~~ ~~and September 25, 2020,~~ the Company’s gross liability for unrecognized tax benefits, excluding interest, was ~~$1.4~~$1.7 million and ~~$1.0~~$1.0 million, respectively. Increases or decreases to interest and penalties on uncertain tax positions are included in the

- 17 -

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.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act) was signed into law in response to the U.S. COVID-19 pandemic, which, among other things, suspends the 80.0% limitation on the deduction for NOLs in taxable years beginning before January 1, 2021, permits a ~~5-year~~ ~~carryback of NOLs arising in taxable years beginning after December 31, 2017 and before January 1, 2021, and generally caps the~~ ~~limitation on the~~

deduction for net interest expense at 50.0% of adjusted taxable income for taxable years beginning in 2019 and 2020. In addition, the CARES Act raises the corporate charitable deduction limit to 25.0% of taxable income and makes qualified improvement property generally eligible for 15-year cost-recovery and 100.0% bonus depreciation. The Company has evaluated the impact of the CARES Act and determined that there was 0 significant impact to the income tax provision for the three and nine months ended September 24, 2021.

~~- 21 -~~

~~On December 27, 2020, the U.S. government enacted the~~ ~~Consolidated Appropriations Act, 2021, which enhances and expands certain provisions of the CARES Act. This legislative act is not expected to have a material impact on the Company’s consolidated financial results.~~

On March 11, 2021, the American Rescue Plan Act of 2021 (“American Rescue Plan”) was signed into law to provide additional relief in connection with the ongoing COVID-19 pandemic. The American Rescue Plan includes, among other things, provisions relating to Paycheck Protection Plan (“PPP”) loan expansion, defined pension contributions, excessive employee remuneration, and the repeal of the election to allocate interest expense on a worldwide basis. The Company does not currently expect that such provisions will have a material impact on the Company’s Condensed Consolidated Financial Statements.

In December 2019, the FASB issued Accounting Standards Update No. 2019-12, “Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes”, as part of its initiative to reduce complexity in the accounting standards. The ASU eliminates certain exceptions from ASC 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 also clarifies and simplifies other aspects of the accounting for income taxes. The guidance is effective for fiscal years beginning after December 15, 2020 and for interim periods within those fiscal years. The Company adopted ASU 2019-12 on January 1, 2021. The adoption of this standard did not have a material impact on the Company’s Condensed Consolidated Financial Statements.

9.8. RETIREMENT PLANS

Defined Benefit Plan

Cinos Korea has a noncontributory defined benefit pension plan covering substantially all of its employees upon their retirement. Ham-Let has noncontributory defined benefit pension plans covering its employees in Israel and South Korea 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 plan are reasonable based on its experience and market conditions.

QGT, through its wholly-owned subsidiary in Singapore, 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 ~~its~~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 fair values of the noncontrolling interests were estimated based on the values of Cinos Korea and Cinos China on a ~~100.0%~~100.0% basis. The values were calculated based on the pro-rata portion of total QGT earnings before interest expense, taxes, depreciation and amortization contributed by each entity.

~~12.~~ 11. EMPLOYEE STOCK PLANS

The Company grants stock awards in the form of ~~RSUs~~restricted stock units ("RSUs") and ~~PSUs~~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 0 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.~~goals and market conditions. The Company also grants common stock to its board members in the form of ~~RSAs,~~restricted stock awards ("RSAs"), which vest on the earlier of 1) the next Annual Shareholder Meeting, or 2) 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, net of expected forfeitures, is amortized on a straight-line basis over the awards’ vesting period and is adjusted for ~~subsequent changes in estimated forfeitures related to all equity-based awards and~~ performance as it relates to PSUs.Under the new PSU program, which is 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 0 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 participants’ PSU award granted to determine the number of total units earned.

At the end of the three-year performance period, the total units earned, if any, are adjusted by applying two modifiers, each ranging from 25% to (25)% based on (i) the Company’s relative total shareholder return (“TSR”) compounded annual growth rate (“CAGR”) which is based on the Company’s stock price changes relative to a group of peer companies and (ii) the “average annual difference in operating margin” is defined as non-GAAP operating margin divided by GAAP total revenue comparing the annual operating plan to actual results.

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 on-going basis, we evaluate our estimates and judgments, including those related to inventories, income taxes, business combinations 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,

Total Products revenues increased in the three ~~and nine~~ months ended ~~September 24, 2021,~~April 1, 2022, compared to the same periods in the prior year, primarily due to an increase in customer demand in the semiconductor industry, in particular, the wafer fabrication equipment industry and in part due to the ~~inclusion~~acquisition of Ham-Let. Ham-Let contributed ~~$64.4 million and $122.6~~$64.5 million of revenues for the three ~~and nine~~ month periods ended ~~September 24, 2021.~~April 1, 2022. Total Services revenues increased in the three ~~and nine~~ months ended ~~September 24, 2021,~~April 1, 2022, compared to the same period in the prior year, primarily due to increases in demand across our customer base.

On a geographic basis, revenues represent products shipped from or services performed at our U.S. and international locations. For the three ~~and nine~~ months ended ~~September 24, 2021,~~April 1, 2022, both U.S. and international revenues increased due to an overall global increase in semiconductor capital equipment and general industry demand.

Total cost of revenues increased ~~$150.9 million and $370.8~~ for the three ~~and nine~~ months ended ~~September 24, 2021~~April 1, 2022 due to higher demand for both Products and Services and in part bydue to the ~~inclusion~~acquisition of ~~Ham-Let operations.~~Ham-Let.

Cost of Products revenues consists of purchased materials, direct labor and manufacturing overhead. Cost of Products revenues increased ~~$149.8~~$115.9 million for the three months ended ~~September 24, 2021~~April 1, 2022 compared to the same period in the prior year, due to the ~~inclusion~~acquisition of Ham-Let, higher volume of sales driving increased material costs, of $115.0 million (including $2.4 million of materials costs resulting from the step-up in value of Ham-Let’s inventories at the acquisition/valuation date that were sold through during the quarter ended September 24, 2021 and $0.7 million of inventory written off related to end of life products). Also contributing to the increase in Cost of Product revenues, wereas well as higher direct labor spending ~~of $21.6 million~~ and ~~higher~~ overhead costs of $13.2 million (including $0.7 million of intangible amortization resulting from the acquisition of Ham-Let).

Interest expense increased in the three ~~and nine~~ months ended ~~September 24, 2021~~April 1, 2022, compared to the same periods in the prior year, due to a higher average debt balance offset partially by lower interest rates resulting from lower LIBOR rates.

Other income (expense), net ~~increased $0.3~~decreased $4.3 million in the three months ended ~~September 25, 2021,~~April 1, 2022, compared to the same period in the prior year, mainly due to ~~foreign exchange losses~~an absence of ~~$0.7~~an $11.6 million ~~offset by a change~~loss in the fair value of ~~the Cinos Korea common stock purchase obligation of $0.3 million.~~

~~Other income (expense), net increased $3.2 million in the~~ ~~nine months ended September 24, 2021, compared to the same period in the prior year, due to an increase of $11.6 million in the fair value of~~ forward ~~hedge~~ contracts related to the non-U.S. dollar-denominated acquisition price of Ham-Let, ~~a $1.1 million increase in foreign exchange losses~~ and ~~a decrease of $0.6 million in government grants income. These increases were partially offset by~~ insurance proceeds of $7.3 million received for the reimbursement of our losses in the Cinos Korea ~~fire and by the absence of $3.0 million loss from the change in fair value of the contingent earn-out in fiscal 2021.~~fire.

The change in respective 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 effective tax rate includes the effects of the mandatory capitalization and amortization of research and development expenses incurred in 2022, as required by the 2017 Tax Cuts and Jobs Act. The mandatory capitalization requirement also increases our cash tax liabilities. If the mandatory capitalization requirement is deferred by a change in law, our effective tax rate in 2022 and our cash tax liabilities could be lower.

Company management continuously evaluates the need for a valuation allowance on its deferred tax assets and, as of ~~September 24, 2021,~~April 1, 2022, concluded that a full valuation allowance on its federal, state and ~~state~~certain of its foreign deferred tax assets remained appropriate.

The following table summarizes the Condensed Consolidated Statements of Cash Flow information:

We believe we have ~~required~~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 ~~September 24, 2021,~~April 1, 2022, we had cash of ~~$457.0~~$367.0 million compared to ~~$200.3~~$466.5 million as of December ~~25, 2020.~~31, 2021. 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 ~~September 24, 2021.~~April 1, 2022.

Our subsidiary Ham-Let, has an existing factoring arrangement with a financial institution in which a portion of its accounts receivable are sold on a non-recourse basis. For the three months ended April 1, 2022, Ham-Let factored $7.7 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 ~~financings.~~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 ~~financings.~~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.

~~In prior years,~~As of April 1, 2022, we ~~determined~~have cash of approximately $298.5 million in our foreign subsidiaries. It is not practicable to determine the tax liability that ~~a portion of~~might be incurred if the ~~current year and future year~~undistributed earnings of ~~one of our China subsidiaries may be remitted in the future to one of our~~these foreign subsidiaries ~~outside of China and, accordingly, we provided for the related withholding taxes in our Condensed Consolidated Financial Statements.
