**ULTRA CLEAN HOLDINGS, INC.** 

**NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS** 

**(Unaudited)** 

**1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES** 

*Organization* — Ultra Clean Holdings, Inc., (the "Company" or "UCT") a Delaware corporation, was founded in November 2002 and became a publicly traded company on the NASDAQ Global Market in March 2004. The Company is a leading developer and supplier of critical subsystems, components, parts, and ultra-high purity cleaning and analytical services, primarily for the semiconductor industry. UCT offers its customers an integrated outsourced solution for major subassemblies, improved design-to-delivery cycle times, design for manufacturability, prototyping and part and component manufacturing, as well as tool chamber parts cleaning and coating, and micro-contamination analytical services. 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, sub-fab process equipment support racks, 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.

*Basis of Presentation* — The unaudited Condensed Consolidated Financial Statements included in this quarterly report on Form 10-Q include the accounts of the Company and its majority-owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP. This financial information reflects all adjustments which are, in the opinion of the Company, normal, recurring and necessary for a fair statement of the results of operations, financial position, and cash flows for the interim periods presented. Certain information and footnote disclosures normally included in our annual financial statements, prepared in accordance with U.S. GAAP, have been condensed or omitted from the interim financial statements in this Quarterly Report on Form 10-Q. Therefore, these unaudited financial statements should be read in conjunction with the Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended December 27, 2024.

*Fiscal Year* — The Company uses a 52-53 week fiscal year ending on the Friday nearest December 31. All references to quarters refer to fiscal quarters and all references to years refer to fiscal years.

*Principles of Consolidation* — The Company's Condensed Consolidated Financial Statements include the accounts of the Company and its majority-owned subsidiaries and all intercompany accounts and transactions have been eliminated upon consolidation.

*Significant Accounting Policies* — There were no changes to the accounting policies disclosed in Note 1, Organization and Significant Accounting Polices of the Company's Annual Report on Form 10-K for the year ended December 27, 2024 that had a material impact on the Company's condensed consolidated financial statements and related notes.

***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 No. 2023-09 prospectively in the first quarter of fiscal year 2025. The adoption did not have a material impact on the Company's interim condensed consolidated financial statements but is expected to result in expanded annual income tax disclosures beginning with the Company's Form 10-K for the fiscal year ending December 26, 2025.

***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"). ASU No. 2024-03 requires entities to provide disaggregated disclosure of certain expense categories, including but not limited to, inventory purchases, employee compensation, depreciation, amortization, and depletion, within relevant income statement captions.

<u>[Index to Notes](#i00a6705ed68349f3a776382b0e891bd7_31)</u>

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, 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 to be applied prospectively, although retrospective application is allowed.

The Company is currently evaluating the impact of ASU 2024-03 and ASU 2025-01 on its financial statement disclosures.

**2. BALANCE SHEET INFORMATION** 

***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, while sale proceeds in excess of the fair value of factored receivables are reflected in cash flows from financing activities on the Consolidated Statements of Cash Flows.

The Company currently has two active receivables factoring arrangements. One arrangement allows for the factoring of up to $25.0 million of uncollected receivables originated within the United States. The second arrangement allows for the factoring of up to $12.0 million of uncollected receivables originated within the EMEA and Asia Pacific regions. During the three and six months ended June 27, 2025, the Company received cash proceeds of $23.0 million and $29.4 million, respectively, from the sales of accounts receivables under its factoring arrangements. As of June 27, 2025, there were a total of $25.4 million of uncollected receivables that had been sold and removed from the Company's Condensed Consolidated Balance Sheets.

**3. FAIR VALUE**

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

---

| | | | | |

| &nbsp;&nbsp;&nbsp;Contingent earn-out | $0.1 | $— | $— | $0.1 |

The estimated fair value of pension obligation is based on expected years of service and average compensation. The valuation model used to value pension obligation utilizes mortality rate, inflation, interest rate risks and changes in the life expectancy for pensioners. These assumptions are routinely made in the appraisal process by the independent actuary resulting in a Level 3 classification. As of June 27, 2025, the Company's aggregate pension benefit obligations was $14.0 million and the fair value of the pension plan assets was $11.5 million, resulting in underfunded pension benefit obligations of $2.5 million. The Company recognizes the overfunded or underfunded status of defined benefit pension plans, measured as the difference between the fair value of the plan assets and the benefit obligation. Each overfunded plan is recognized as an asset and each underfunded plan is recognized as a liability.

Prior to fiscal year 2025, the Company measured its contingent earn-out liabilities at fair value on a recurring basis using a Monte Carlo simulation model. The significant unobservable inputs used in the model included the forecasted operating profit of the acquired business during the earn-out period ending in calendar year 2025. Significant increases or decreases to the forecasted results would result in a significantly higher or lower liability, with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Ultimately, the liability will be equivalent to the amount paid, and the difference between the fair value estimate and amount paid will be recorded in earnings. The amount paid that is less than or equal to the contingent earn-out liability on the acquisition date is reflected as cash used in financing activities in the consolidated statements of cash flows. Any amount paid in excess of the contingent earn-out liability on the acquisition date will be reflected as cash used in operating activities in the consolidated statements of cash flows.

In the first quarter of fiscal year 2025, the Company reassessed the fair value of the contingent earn-out associated with the acquisition of HIS, decreasing the fair value from $0.1 million as of December 27, 2024, to zero. The $0.1 million decrease was recorded as Other income (expense), net in the Condensed Consolidated Statements of Operations for the six months ended June 27, 2025. The change in fair value was primarily due to lower-than-expected financial performance. There was no change in the fair value estimate during the second quarter of fiscal year 2025.

For the three and six months ended June 28, 2024, the Company recognized gains of $24.1 million and $22.8 million, respectively, related to the change in the fair value of contingent earn-out liability. These amounts were recorded within other income (expense), net in the Condensed Consolidated Statements of Operations.

There were no transfers in or out of any level during the three and six months ended June 27, 2025 and June 28, 2024. Fair value adjustments were noncash, and therefore did not impact the Company's liquidity or capital resources.

**4. GOODWILL AND INTANGIBLE ASSETS** 

***Goodwill***

Goodwill represents the excess of the consideration transferred over the fair value of the tangible and identifiable intangible assets acquired, less the liabilities assumed in a business combination. Changes in the carrying amount of goodwill by segment during the six months ended June 27, 2025, were as follows:

---

| | | | |
|:---|:---|:---|:---|
| **(In millions)** | **Products** | **Services** | **Total** |
| Balance at December 27, 2024 | $191.8 | $73.5 | $265.3 |
| Impairment of Goodwill | (77.6) | (73.5) | (151.1) |
| Balance at June 27, 2025 | $114.2 | $— | $114.2 |

---

During the first quarter of 2025, the Company combined the HIS and Core Products reporting units following a reevaluation of its reporting structure. Impairment assessments were performed immediately before and after the change, and it was concluded that the fair values of these reporting units exceeded their carrying values on both an individual and combined basis. Following this reevaluation, the Company is organized into four reporting units: Core Products, Fluid Solutions, Fluid Delivery Systems, and Services. During the first quarter of 2025, the Company did not recognize any impairment charges or additions to goodwill.

During the second quarter of 2025, the Company experienced a sustained decline in the market price of its common stock. As a result, the Company's market capitalization became much closer to, and at times fell below, the carrying value of its net assets. The decline in market capitalization, combined with other factors specific to each reporting unit, such as changes in market conditions and financial performance, was identified as a triggering event under ASC 350, Intangibles—Goodwill and Other, requiring the Company to perform an interim goodwill impairment test.

The Company performed a quantitative goodwill impairment test for each of its four reporting units by comparing the estimated fair value of each reporting unit to its respective carrying value. Based on the results of this assessment, goodwill impairments were identified in the Fluid Solutions and Services reporting units. As a result, the Company recorded a total goodwill impairment charge of $151.1 million during the second quarter of 2025, of which $77.6 million was attributable to the Products segment and $73.5 million was attributable to the Services segment. No impairments were identified in the Core Products or Fluid Delivery Systems reporting units.

For the quantitative goodwill impairment tests performed, the fair value estimates of the Company's reporting units were derived from an income approach. Under the income approach, the Company estimated the fair value of the reporting unit based on the present value of estimated future cash flows, which the Company considers to be a Level 3 unobservable input in the fair value hierarchy. The Company prepared cash flow projections based on management's estimates of revenue growth rates and operating margins, taking into consideration historical performance and the current macroeconomic,

------

<u>[Index to Notes](#i00a6705ed68349f3a776382b0e891bd7_31)</u>

industry, and market conditions. The Company based the discount rate on the weighted-average cost of capital considering Company-specific characteristics and changes in the reporting unit's projected cash flows.

Following the impairment of goodwill recorded in the second quarter of 2025, there is no goodwill recorded in the Fluid Solutions reporting unit or in the Services reporting unit. The fair values of the Core Products reporting unit and the Fluid Delivery Systems reporting unit were each substantially in excess of their respective carrying values.

Prior to testing goodwill for impairment, the Company evaluated the recoverability of its long-lived assets under ASC 360, Property, Plant, and Equipment, and determined that no impairment of long-lived assets was required.

***Intangible Assets***

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

---

| | | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|:---|
| | | **As of June 27, 2025** | **As of June 27, 2025** | **As of June 27, 2025** | **As of December 27, 2024** | **As of December 27, 2024** | **As of December 27, 2024** |
| **(Dollars in millions)** |<br>**Useful Life <br>(In years)** | **Gross <br>Carrying <br>Amount** | **Accumulated <br>Amortization** | **Carrying <br>Value** | **Gross <br>Carrying <br>Amount** | **Accumulated <br>Amortization** | **Carrying <br>Value** |
| Customer relationships | 6 - 10 | $207.2 | $(126.8) | $80.4 | $207.2 | $(117.4) | $89.8 |
| Recipes | 20 | 73.2 | (25.0) | 48.2 | 73.2 | (23.2) | 50.0 |
| Intellectual property/know-how | 7 - 15 | 48.9 | (25.0) | 23.9 | 48.9 | (22.8) | 26.1 |
| Tradename | 4 - 6\* | 32.5 | (23.2) | 9.3 | 32.5 | (22.9) | 9.6 |
| Standard operating procedures | 20 | 8.6 | (2.9) | 5.7 | 8.6 | (2.7) | 5.9 |
| Developed technology | 5 | 4.6 | (1.5) | 3.1 | 4.6 | (1.1) | 3.5 |
| &nbsp;&nbsp;&nbsp;Total |  | $375.0 | $(204.4) | $170.6 | $375.0 | $(190.1) | $184.9 |

---

\*The Company concluded that the asset life of UCT tradename of $9.0 million is indefinite and is therefore not amortized but is 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.

The Company amortizes its intangible assets on a straight-line or accelerated basis over the estimated economic life of the assets. Amortization expense was approximately $7.0 million and $14.3 million for the three and six months ended June 27, 2025, respectively. For the three and six months ended June 28, 2024, amortization expense was approximately $7.6 million and $15.3 million, respectively. Amortization expense related to recipes, standard operating procedures, developed technology and certain intellectual property/know-how is included in cost of revenues, while the remaining amortization expense is included in general and administrative expense. As of June 27, 2025, future estimated amortization expense is expected to be as follows:

---

| | |
|:---|:---|
| **(In millions)** | **Amortization <br>Expense** |
| 2025 (remaining in year) | $13.8 |
| 2026 | 27.2 |
| 2027 | 26.9 |
| 2028 | 23.8 |
| 2029 | 16.2 |
| Thereafter | 53.7 |
| Total | $161.6 |

**5. BORROWING ARRANGEMENTS**

On October 8, 2024, the Company entered into the Seventh Amendment to its Credit Agreement, originally dated August 27, 2018, as amended. The Seventh Amendment, among other changes, reduced the interest rate on the term loan facility by 0.25% per annum.

The term loan facility has a maturity date of February 25, 2028. The Company pays monthly interest payments in arrears and quarterly principal payments of 0.625% of the outstanding principal balance since October 8, 2024, with the remaining principal paid upon maturity.

The revolving credit facility has aggregate commitments of $150.0 million and a maturity date of August 27, 2027. The Company pays a quarterly commitment fee in arrears equal to 0.25% of the average daily available commitment outstanding. Outstanding letters of credit reduce the availability of the revolving credit facility and, as of June 27, 2025, the Company had $146.4 million, net of $3.6 million of outstanding letters of credit, available under this revolving credit facility.

The letter of credit facility has an available commitment of $50.0 million and a maturity date of August 27, 2027. The Company pays a quarterly fee in arrears on the dollar equivalent of all outstanding letters of credit equal to the applicable margin for the revolving credit facility, and a fronting fee equal to 0.125% of the undrawn and unexpired amount of each letter of credit. As of June 27, 2025, the Company had $3.6 million of outstanding letters of credit and $46.4 million of available commitments remaining under the letter of credit facility.

Under the Credit Agreement, 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 "Term SOFR" (as defined in the Credit Agreement), plus the applicable margin. The applicable margin for the Term Loan is equal to a rate per annum equal 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) 3.00% for such Term SOFR loans and (y) 2.00% for such ABR term loans or (ii) at all other times, (x) 3.25% for such Term SOFR loans and (y) 2.25% 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 Term SOFR loans, the last day of each relevant interest period and, in the case of any interest period longer than three months, on each successive date three months after the first day of such interest period.

At June 27, 2025, the Company had an outstanding amount under the Term Loan of $484.5 million, gross of unamortized debt issuance costs of $6.1 million. As of June 27, 2025, the interest rate on the outstanding Term Loan was 7.6%.

The Credit Agreement requires the Company to maintain certain financial covenants including a minimum consolidated fixed charge coverage ratio and a maximum consolidated leverage ratio as of the last day of any fiscal quarter. The Company currently has no revolving loans outstanding under the Credit Agreement. As of June 27, 2025, the Company was in compliance with the financial covenants contained within the Credit Agreement.

The Company maintains credit agreements with a local bank in Czechia and with a financial institution in Israel, which provide for revolving credit facilities of up to 7.0 million euros (approximately $8.2 million) and $5.0 million, respectively.

As of June 27, 2025, the Company's total bank debt was $478.4 million, net of unamortized debt issuance costs of $6.1 million. As of June 27, 2025, the Company had $146.4 million, $5.0 million, and 5.5 million euros (approximately $6.4 million) available to draw from its credit facilities in the U.S., Israel and Czechia, respectively.

The fair value of the Company's long-term debt is based on Level 2 inputs, and was determined using quoted prices for similar instruments in inactive markets. The Company's carrying value approximates fair value for the Company's long-term debt.

**6. INCOME TAX** 

The Company's effective tax rate was (4.7)% and 28.3% for the three months ended June 27, 2025 and June 28, 2024, respectively, and (9.8)% and 56.4% for the six months ended June 27, 2025 and June 28, 2024, respectively.

The Company recorded income tax provision of $7.2 million and $8.5 million for the three months ended June 27, 2025 and June 28, 2024, respectively, and $14.6 million and $18.4 million for the six months ended June 27, 2025 and June 28, 2024, respectively.

The change in respective tax rates reflects primarily reflects the goodwill impairment booked in the second quarter of fiscal year 2025, 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 valuation allowances on deferred tax assets. Company

------

<u>[Index to Notes](#i00a6705ed68349f3a776382b0e891bd7_31)</u>

management continuously evaluates the need for a valuation allowance and, as of June 27, 2025, concluded that a full valuation allowance on its U.S. federal and state and certain of its foreign deferred tax assets was still appropriate.

As of June 27, 2025 and December 27, 2024, the Company's gross liability for unrecognized tax benefits, excluding interest, was $5.0 million and $2.3 million, respectively. Increases or decreases to interest and penalties on uncertain tax positions are included in the income tax provision in the Condensed Consolidated Statements of Operations. Although it is possible that some of the unrecognized tax benefits could be settled within the next twelve months, the Company cannot reasonably estimate the outcome at this time.

The Organization for Economic Co-operation and Development and the G20 Inclusive Framework on Base Erosion and Profit Shifting (the "Inclusive Framework") have put forth Pillar Two proposals that ensure a minimal level of taxation. Several countries in which the Company operates have adopted legislation to implement the Inclusive Framework's global corporate minimum tax rate of fifteen percent. This legislation became effective in certain jurisdictions the Company operates in for the current fiscal year, ending December 26, 2025. Based on the Company's current analysis of the enacted Pillar Two provisions and transitional safe harbor provisions, Pillar Two will not have a significant impact on the Company's financial statements for fiscal year 2025.

On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was signed into law enacting significant changes to U.S. tax and related laws. Some of the provisions of the new tax law affecting corporations include, but are not limited to, expensing of domestic research expenses, increasing the limit of the deduction of interest expense deduction to thirty percent of EBITDA, and one hundred percent bonus depreciation on eligible property acquired after January 19, 2025. The Company is currently evaluating the impact the new tax law will have on its financial condition and results of operations. Preliminarily, the Company does not anticipate a material change to its effective income tax rate and its net deferred income tax assets as the Company maintains a full valuation allowance for all U.S. deferred tax assets. The impact of the tax law changes from the OBBBA will be included in the Company's financial statements beginning in the three months ending September 30, 2025.

**7. RETIREMENT PLANS**

***Defined Benefit Plans***

Cinos Korea has a noncontributory defined benefit pension plan covering substantially all of its employees upon their retirement. The Company's entities in Israel also have noncontributory defined benefit pension plans covering their employees upon their retirement. The benefits for these plans are based on expected years of service and average compensation. The net period costs are recognized as employees render the services necessary to earn the postretirement benefits. The Company records annual amounts relating to the pension plan based on calculations that incorporate various actuarial and other assumptions, including discount rates, mortality, assumed rates of return, compensation increases and turnover rates. The Company reviews its assumptions on an annual basis and makes modifications to the assumptions based on current and expected rates of return and trends when it is appropriate to do so. The effect of modifications to those assumptions is recorded in accumulated other comprehensive income and amortized to net periodic cost over future periods using the corridor method. The Company believes that the assumptions utilized in recording its obligations under the plans are reasonable based on its experience and market conditions.

As of June 27, 2025, the benefit obligation of the plans was $14.0 million and the fair value of the benefit plan assets was $11.5 million which are invested in several fixed deposit accounts with financial institutions. As of June 27, 2025, the underfunded balance of the plans of $2.5 million has been recorded by the Company and is included in other liabilities.

Amounts recognized in accumulated other comprehensive income (loss) and contributions made for the three and six months ended June 27, 2025 and June 28, 2024 were negligible.

As of June 27, 2025, the Company's future estimated payment obligations for the respective fiscal years are as follows:

***Employee Savings and Retirement Plan*** 

The Company sponsors a 401(k) savings and retirement plan (the "401(k) Plan") for all U.S. employees who meet certain eligibility requirements. Participants can elect to contribute to the 401(k) Plan, on a pre-tax basis, up to 25% of their salary to a maximum of the IRS limit. The Company matches 50.0% of each employee's contribution, up to a maximum of 6% of the employee's eligible earnings. The Company made discretionary employer contributions to its 401(k) Plan of $0.9 million and $1.9 million for the three and six months ended June 27, 2025, respectively, and $0.9 million and $1.9 million for the three and six months ended June 28, 2024, respectively.

**8. COMMITMENTS AND CONTINGENCIES** 

***Commitments***

The Company leases real estate and equipment under various non-cancelable operating leases.

***Contingencies***

From time to time, the Company is subject to various legal proceedings and claims, either asserted or unasserted, that arise in the ordinary course of business. Although the outcome of the various legal proceedings and claims individually or in the aggregate cannot be predicted with certainty, the Company has not had a history of outcomes to date that have been material to the Condensed Consolidated Statements of Operations and does not believe that any of these proceedings or other claims will have a material adverse effect on its consolidated financial condition, results of operations or cash flows.

**9. STOCKHOLDERS' EQUITY AND NONCONTROLLING INTERESTS** 

***Treasury Stock***

On October 20, 2022, the Board of Directors approved a share repurchase program authorizing the Company to purchase up to an aggregate of $150 million of the Company's common stock over a three-year period.

For the three and six months ended June 27, 2025, approximately 0.2 million shares were repurchased under this program with aggregate cost of $3.4 million. No shares were repurchased under this program for the three and six months ended June 28, 2024.

As of June 27, 2025, 1.5 million shares had been repurchased under the program and they are held in treasury stock. The Company records treasury stock using the cost method. The Company may reissue these treasury shares as part of its stock-based compensation programs.

***Non-controlling Interests***

The Company owns part of the outstanding shares of Cinos Korea, a South Korean company that provides outsourced cleaning and recycling of precision parts for the semiconductor industry through its operating facilities in South Korea and through a partial interest in Cinos China.

The carrying value of the remaining interest held by another shareholder in Cinos Korea and the remaining interest in Cinos China are presented as noncontrolling interests in the accompanying Condensed Consolidated Financial Statements. Noncontrolling interests are calculated based on minority ownership percentages, representing the proportionate share of net assets in the balance sheet and net income (loss) in the income statement.

**10. EMPLOYEE STOCK PLANS**

***Employee Stock Plans***

The Company grants stock awards in the form of restricted stock units ("RSUs") and performance stock units ("PSUs") to its employees as part of the Company's long-term equity compensation plan. These stock awards are granted to employees with a unit purchase price of zero dollars and typically vest over three years, subject to the employee's continued service with the Company and, in the case of PSUs, subject to achieving certain performance goals and market conditions. The Company also grants common stock to its board members in the form of restricted stock awards ("RSAs"), which vest on the earlier of the next Annual Shareholder Meeting, or 365 days from date of grant. The aggregate number of shares authorized for issuance under the plan is 1.3 million.

Stock-based compensation expense includes compensation costs related to estimated fair values of awards granted. The estimated fair value of the Company's equity-based awards is amortized on a straight-line basis over the awards' vesting period and is adjusted for performance as it relates to PSUs.

The following table shows the Company's stock-based compensation expense included in the Condensed Consolidated Statements of Operations:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Three Months Ended** | **Three Months Ended** | **Six Months Ended** | **Six Months Ended** |
| **(In millions)** | **June 27,<br>2025** | **June 28,<br>2024** | **June 27,<br>2025** | **June 28,<br>2024** |

| General and administrative | 6.3 | 3.4 | 8.2 | 6.1 |
| Total stock-based compensation | $7.1 | $4.5 | $10.0 | $8.0 |

---

(1)Stock-based compensation expense capitalized in inventory for the three and six months ended June 27, 2025 and June 28, 2024 were immaterial.

For the three and six months ended June 27, 2025, 0.7 million and 0.8 million RSUs were granted with a weighted average fair value of $22.12 and $22.35 per share, respectively. For the three and six months ended June 28, 2024, 451 thousand and 475 thousand RSUs were granted with a weighted average fair value of $41.32 and $41.47 per share, respectively.

For the three and six months ended June 27, 2025, 98 thousand PSUs were granted with fair value of $2.2 million, while 125 thousand PSUs were granted for the three and six months ended June 28, 2024, with a fair value of $5.8 million.

For the six months ended June 27, 2025, 1 thousand RSAs were granted with a weighted fair value of $24.96 per share. For the three and six months ended June 28, 2024 26 thousand RSAs were granted with a weighted fair value of $46.17 per share.

The following table summarizes the Company's combined RSU, PSU and RSA activity for the six months ended June 27, 2025:

---

| | | |
|:---|:---|:---|
| **(In millions)** | **Number of <br>Shares** | **Aggregate <br>Intrinsic <br>Value** |
| Outstanding at December 27, 2024 | 1.4 | $52.0 |
| Granted | 0.9 |  |
| Vested | (0.4) |  |
| Forfeited | (0.3) |  |
| Outstanding at June 27, 2025 | 1.6 | $35.3 |
| Expected to vest at June 27, 2025 | 1.5 | $35.1 |

---

As of June 27, 2025, approximately $36.0 million of unrecognized stock-based compensation cost related to employee and director awards remains to be amortized on a straight-line basis over a weighted average period of 2.1 years, and will be adjusted for subsequent changes in future grants.

Under the current PSU program, performance goals are set at the time of grant and performance is reviewed at the end of a three-year period. The percentage to be applied to each participant's target award ranges from zero to 200%, based upon the extent to which the financial performance goals are achieved. If specific performance threshold levels for the financial

------

<u>[Index to Notes](#i00a6705ed68349f3a776382b0e891bd7_31)</u>

goals are met on an annual basis, the amount earned for that element will be applied to one-third of the participant's PSU award granted to determine the number of total units earned.

Recipients of PSU awards generally must remain employed by the Company on a continuous basis through the end of the three-year performance period in order to receive any amount of the PSUs covered by that award. In events such as death, disability or retirement, the recipient may be entitled to pro-rata amounts of PSUs as defined in the Plan. Target shares subject to PSU awards do not have voting rights of common stock until earned and issued following the end of the three-year performance period.

***Employee Stock Purchase Plan***

The ESPP permits employees to purchase common stock at a discount through payroll withholdings at certain specified dates (purchase period) within a defined offering period. The purchase price is 85% of the fair market value of the common stock at the end of the purchase period and is intended to qualify as an "employee stock purchase plan" under Section 423 of the Internal Revenue Code. The aggregate number of shares authorized for issuance under the plan is 1.1 million.

During the three and six months ended June 27, 2025. 72 thousand shares were issued under the ESPP. The Company recorded $0.2 million and $0.4 million of expense related to ESPP for the three and six months ended June 27, 2025

During the three and six months ended June 28, 2024, 42 thousand shares were issued under the ESPP. The Company recorded $0.2 million and $0.3 million of expense related to ESPP for the three and six months ended June 28, 2024.

**11. REVENUE RECOGNITION**

Revenue is recognized when the Company satisfies the performance obligations as evidenced by the transfer of control of the promised goods or services to the Company's customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services.

The Company sells its products and services primarily to customers in the semiconductor capital equipment industry. The Company's revenues are highly concentrated and therefore highly dependent upon a small number of customers. Typical payment terms with our customers range from thirty to sixty days.

The Company's Products business segment provides warranty on its products for a period of up to two years and provides for warranty costs at the time of sale based on historical activity. Determination of the warranty reserve requires the Company to make estimates of product return rates and expected costs to repair or replace the products under warranty. If actual return rates and/or repair and replacement costs differ significantly from these estimates, adjustments to recognize additional cost of revenues may be required in future periods. The warranty reserve is included in other current liabilities on the Condensed Consolidated Balance Sheets and is not considered significant.

The Company's products are manufactured and services provided at the Company's locations throughout the Americas, Asia Pacific and Europe and the Middle East ("EMEA"). Sales to customers are initiated through a purchase order and are governed by our standard terms and conditions, written agreements, or both. Revenue is recognized when performance obligations under the terms of an agreement with a customer are satisfied; generally, this occurs with the transfer of control of the products or when the Company provides the services. Based on the enforceable rights included in our agreements or prevailing terms and conditions, products produced by the Company without an alternative use are not protected by an enforceable right of payment that includes a reasonable profit throughout the duration of the agreement. Consignment sales are recognized in revenue at the earlier of the period that the goods are consumed or after a period of time subsequent to receipt by the customer as specified by terms of the agreement, provided control of the promised goods or services has transferred.

Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Sales, value-added, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. Certain of our customers may receive cash-based incentives, such as rebates or credits, which are accounted for as variable consideration. We estimate these amounts based on the expected amount to be provided to customers and reduce revenues recognized. As of June 27, 2025, the total unpaid rebates amounted to $1.8 million, of which $1.1 million was recorded as a reduction to accounts receivable, and $0.7 million was recorded within accounts payable. Accruals for unpaid customer rebates of $2.3 million as of December 27, 2024, were netted against accounts receivable. The Company's disaggregated revenues are apportioned by segments within the Company's Condensed Consolidated Statement of Operations. Certain services performed by the Company related to products sold to customers are included in Products revenue in the Condensed Consolidated Statement of Operations. These services are not material for any of the periods presented.

**14. REPORTABLE SEGMENTS**

The Company's Chief Executive Officer is the Company's chief operating decision maker (CODM). The CODM primarily uses income from operations to evaluate each segment's performance and allocate resources, primarily through periodic budgeting and segment performance reviews. Significant expenses within segment operating profit include cost of revenue, research and development, and selling, general and administrative expenses, which are each separately presented on the Company's Condensed Consolidated Statements of Operations.

The Company's reportable segments are determined based on the nature of their revenue streams and the Company's internal organization structure.

The Company prepared financial results based on two operating segments (Products and Services) and two reportable segments (Products and Services).

The following table describes each segment:

---

| | | | |
|:---|:---|:---|:---|
| **Segment** | **Product or Services** | **Primary Markets Served** | **Geographic Areas** |
| Products | Assembly<br>Weldments<br>Machining<br>Fabrication | Semiconductor | Americas<br>Asia Pacific<br>EMEA |
| Services | Cleaning<br>Analytics<br>Coating | Semiconductor | Americas<br>Asia Pacific<br>EMEA |

---

The CODM uses segment operating profit or loss to evaluate performance and to allocate capital resources. Segment operating profit or loss is defined as a segment's income or loss from continuing operations before interest and other income (expense), net and provision for income taxes. Any intercompany sales and associated profit (and any other intercompany items) are eliminated from segment results.

***Overview***

Ultra Clean Holdings, Inc., ("UCT", the "Company" or "We") is a leading developer and supplier of critical subsystems, components, parts, and ultra-high purity cleaning and analytical services primarily for the semiconductor industry. UCT offers its customers an integrated outsourced solution for major subassemblies, improved design-to-delivery cycle times, design for manufacturability, prototyping and part and component manufacturing, as well as tool chamber parts cleaning and coating, and micro-contamination analytical services. We report results for two segments: Products and Services. Our Products segment primarily designs, engineers and manufactures production tools, components and parts, and modules and subsystems for the semiconductor and display capital equipment markets. Products include chemical delivery modules, frame assemblies, gas delivery systems, fluid delivery systems, precision robotics, process modules as well as other high-level assemblies. Our Services segment provides ultra-high purity parts cleaning, process tool part recoating, surface encapsulation and high sensitivity micro contamination analysis primarily for the semiconductor device makers and wafer fabrication equipment ("WFE") markets.

We ship a majority of our products and provide most of our services to U.S. registered customers with both domestic and international locations. In addition to U.S. manufacturing and service operations, we manufacture products and provide parts cleaning and other related services in our Asia Pacific, Europe and Middle East ("EMEA") facilities to support local and U.S. based customers. We conduct our operating activities primarily through our subsidiaries.

Over the long term, we believe the semiconductor market we serve will continue to grow due to multi-year industry demand from a broad range of drivers, such as new process architecture (e.g. gate all around) and memory devices (e.g. high bandwidth memory) necessary for cloud, artificial intelligence ("AI") and machine learning ("ML") applications. We also believe that semiconductor original equipment manufacturers ("OEM") are increasingly relying on partners like UCT to fulfill their expanding capacity requirements. Additionally, our Services business is benefiting as device manufacturers rely on precision cleaning and coating to achieve ever more advanced devices.

***Critical Accounting Estimates***

Our Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States, which require us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses and related disclosure at the date of our Condensed Consolidated Financial Statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to inventories, income taxes, business combinations, contingent earn-out liabilities and goodwill, intangible assets and long-lived assets. We base our estimates and judgments on historical experience and on various other factors that we believe to be reasonable under the circumstances, the results of which form the basis of our judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. We consider certain accounting policies related to revenue recognition, inventory valuation, accounting for income taxes, business combinations, valuation of goodwill, intangible assets and long-lived assets to be critical policies due to the estimates and judgments involved in each.

------

<u>[**Table of Contents**](#i00a6705ed68349f3a776382b0e891bd7_7)</u>

There have been no significant changes to our critical accounting policies, significant judgments and estimates disclosed in our Annual Report on Form 10-K subsequent to December 27, 2024. For further information on our critical and other significant accounting policies and estimates, see Part II, Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" of our Annual Report on Form 10-K for the fiscal year ended December 27, 2024, as filed with the SEC.

**Goodwill**

As discussed in Note 4, Goodwill and Intangible Assets Goodwill to our condensed consolidated financial statements, we performed a quantitative goodwill impairment assessment as of June 27, 2025, which resulted in goodwill impairment charges of $151.1 million related to the Fluid Solutions and Services reporting units. The fair value estimate of each reporting unit was derived from an income approach. Under the income approach, we estimated the fair value of the reporting unit based on the present value of estimated future cash flows. We prepared cash flow projections based on management's estimates of revenue growth rates and operating margins, taking into consideration historical performance and the current macroeconomic, industry, and market conditions. We based the discount rate on the weighted-average cost of capital considering company-specific characteristics and the uncertainty related to the reporting unit's ability to execute on the projected cash flows.

Revenue growth rates, operating margins, and the discount rate applied were significant assumptions used to determine the fair value of each reporting unit. The concluded fair value of our reporting units was reconciled to our market capitalization. The excess of the concluded fair value over our market capitalization represents an implied control premium, which we reviewed for reasonableness by comparison to observed transaction premiums and consideration of specific attributes of the Company.

If the actual results are not consistent with the assumptions and judgments we have made in determining the fair value of our reporting units, we may record additional impairment losses.

The fair values of the Core Products and the Fluid Delivery Systems reporting units, both of which are part of the Products segment, were each substantially in excess of their respective carrying values.

***Results of Operations***

**Fiscal Year**

Our fiscal year is the 52- or 53-week period ending on the Friday nearest December 31. Fiscal year 2025 is a 52-week period ending December 26, 2025 and fiscal year 2024 was a 52-week ended December 27, 2024. The fiscal quarters ended June 27, 2025 and June 28, 2024 were both 13-week periods.

Cost of Products revenues consists of purchased materials, direct labor and manufacturing overhead. For the three and six-month periods ended June 27, 2025, Cost of Products revenues increased by $9.4 million and $45.5 million, respectively, compared to the same periods in the prior year. The increase was primarily driven by higher sales volumes, which led to a $3.5 million increase in material costs for the three-month period, and $34.2 million increase for the six month-period. The remaining increase was attributable to higher labor and overhead costs associated with increased production activity, as well as restructuring activities, merit increases, and inflation.

Services Cost of revenues consists of direct labor, overhead, and materials such as chemicals, gases and consumables. For the three and six-month periods ended June 27, 2025, Services Cost of revenues increased by $2.3 million and $5.6 million, respectively, compared to the same periods in the prior year. Revenue remained essentially flat for the three-month period ended June 27, 2025 compared to the same period in the prior year. The increase in labor costs of $2.3 million for the three-month period was primarily due to higher headcount, overtime, and incentive compensation for a specific location. The increase for the six-month period was driven by a higher volume of service orders, as well as higher headcount, overtime and incentive compensation for a specific location, resulting in a $4.2 million increase.

Gross profit and gross margins fluctuate with revenue levels, product mix, material costs, and labor costs.

Products gross profit and gross margin decreased for the three and six-month periods ended June 27, 2025 compared to the same periods in the prior year primarily due to higher employee and restructuring related costs.

Services gross profit and gross margin decreased for the three and six-month periods ended June 27, 2025 compared to the same periods in the prior year, primarily due to higher cost of revenues driven by increased labor and compensation-related costs at a specific location.

---

Operating profit and operating margin for both Products and Services decreased for the three and six-month periods ended June 27, 2025 compared to the same periods in the prior year. This decline was primarily driven by the goodwill impairment recorded during the second quarter of fiscal year 2025, as well as increases in stock-based compensation and severance costs due to restructuring activities, including both involuntary separations and a voluntary retirement program.

---

General and administrative expenses increased $3.2 million and $7.1 million in the three and six-month periods ended June 27, 2025 compared to the same periods in the prior year.

The increase in the three-month period ended June 27, 2025 was primarily driven by an increase in stock-based compensation and severance payments due to restructuring activities, including both involuntary separations and a voluntary retirement program.

The increase in the six-month period ended June 27, 2025 was primarily driven by increase in stock-based compensation, separation payment made to the previous CEO, and increased restructuring activities, including both involuntary separations and a voluntary retirement program.

---

Interest income decreased in the three and six-month periods ended June 27, 2025 compared to the same periods in the prior year due to lower interest earning balances.

Interest expense decreased for the three and six-month periods ended June 27, 2025 compared to the same periods in the prior year primarily due to lower interest rates and reduced amortization of debt issuance costs.

Other income (expense), net, for the three-month period was primarily comprised of unrealized foreign exchange losses of $4.2 million offset by government grants received of $2.2 million. In the prior period, the Company recognized a $24.1

million gain related to the fair value adjustment of the contingent earn-out from the HIS acquisition which was offset by unrealized foreign exchange losses of $2.8 million million and debt modification costs of $3.6 million.

Other income (expense), net, for the six-month period was primarily comprised of unrealized foreign exchange losses of $3.4 million offset by government grants received of $2.2 million. In the prior period, the Company recognized a $22.8 million million gain related to the fair value adjustment of the contingent earn-out from the HIS acquisition which was offset by unrealized foreign exchange losses of $5.2 million and debt modification costs of $3.6 million.

| Effective tax rate | -4.7% | 28.3% |  | -9.8% | 56.4% |  |

---

The decrease in the effective tax rate for the three and six-month periods ended June 27, 2025 compared to the same periods in the prior year is primarily attributable to the 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 valuation allowances on deferred tax assets. The negative tax rates in the three and six-month periods ended June 27, 2025 are the result of pre-tax losses in those periods compared to pre-tax profits in the comparable periods ended June 28, 2024.

The tax provision for the three and six months ended June 27, 2025 includes the impact of a change in the Company's plans for the earnings of one of its subsidiaries in China. In the past, the Company has asserted that the earnings of our foreign subsidiaries, with the exception of certain of its subsidiaries in Singapore, were considered indefinitely reinvested, thus avoiding the recognition of deferred taxes on the earnings considered indefinitely reinvested.

The negative tax rates in the three and six-month periods ended June 27, 2025 are the result of pre-tax losses during those periods compared to pre-tax profits in the comparable periods ended June 28, 2024. The tax provision for the three and six months ended June 27, 2025 includes the impact of a change in the Company's assertion that earnings from fiscal 2023 and going forward in one of its subsidiaries in China is no longer permanently reinvested. As a result, the Company has recorded a discrete tax expense of $3.4 million in the second quarter of 2025. The Company will also record deferred taxes on the undistributed current and future year earnings of this China subsidiary.

Company management continuously evaluates the need for a valuation allowance on its deferred tax assets and, as of June 27, 2025, concluded that a full valuation allowance on its U.S. federal, state and certain of its foreign deferred tax assets remained appropriate.

<u>[**Table of Contents**](#i00a6705ed68349f3a776382b0e891bd7_7)</u>

Our primary cash inflows and outflows were as follows:

• For the six-month period ended June 27, 2025, we generated cash from operating activities of $57.4 million compared to $33.0 million for the same period in the prior year. The $24.4 million increase in net cash provided by operating activities was primarily driven by a $25.9 million favorable change in net working capital.

• The major contributors in net changes in operating assets and liabilities for the six-month period ended June 27, 2025 were as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Accounts receivable decreased $34.3 million primarily due to the timing of shipments and collections, as well as the sale of accounts receivable through factoring arrangements. Inventories decreased by $5.4 million as inventory on hand was consumed. Operating lease assets and liabilities decreased $11.1 million, reflecting lease payments and amortization. Prepaid expenses and other current assets increased by $7.8 million due to advance payments and prepayments related to various expenses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Accounts payable decreased $11.9 million, other liabilities by $4.0 million, accrued compensation and related benefits by $2.6 million, and income tax payable by $4.2 million, as a result of elevated prepayment activity.

• Net cash used in investing activities during the six-month periods ended June 27, 2025 and June 28, 2024 consisted primarily of $29.2 million and $31.0 million purchases of property, plant and equipment, respectively.

• During the six-month period ended June 27, 2025, cash used in financing activities was $18.8 million compared to $12.5 million cash provided in the same period in the prior year. The $31.3 million increase in net cash used by financing activities was primarily due to $31.5 million net cash proceeds from bank borrowings related to the debt modification in the prior period.

We believe we have sufficient capital to fund our working capital needs, satisfy our debt obligations, maintain our existing capital equipment, purchase new capital equipment and make strategic acquisitions from time to time. As of June 27, 2025, we had cash and cash equivalents of $327.4 million compared to $313.9 million as of December 27, 2024. 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 June 27, 2025.

In the second quarter of 2025, we entered into a factoring agreement with a financial institution to sell certain accounts receivables under a non-recourse agreement. Under the arrangement, we sell certain trade receivables on a non-recourse basis and account for the transaction as a sale of the receivables. The financial institution assumes the full risk of collection, without recourse to the Company in the event of a loss. As part of the factoring arrangements, we perform certain collection and administrative functions for the receivables sold. The applicable receivables are removed from our consolidated balance sheet when the cash proceeds are received by us. We utilize this factoring arrangement as part of our financing for working capital. For the three and six months ended June 27, 2025, we sold accounts receivable totaling $17.8 million under this arrangement.

In addition, Fluid Solutions has an existing factoring agreement with a financial institution to sell certain accounts receivables under a non-recourse agreement. For the three and six month periods ended June 27, 2025, we sold accounts receivable totaling $5.2 million and $11.6 million, respectively under this arrangement.

We anticipate that our existing cash and cash equivalents balance and operating cash flow will be sufficient to service our indebtedness and meet our working capital requirements and technology development projects for at least the next twelve months. The adequacy of these resources to meet our liquidity needs beyond that period will depend on our growth, the size and number of any acquisitions, the state of the worldwide economy, our ability to meet our financial covenants with our credit facility, the cyclical expansion or contraction of the semiconductor capital equipment industry and the other industries we serve and capital expenditures required to meet possible increased demand for our products.

In order to expand our business or acquire additional complementary businesses or technologies, we may need to raise additional funds through equity or debt financing. If required, additional financing may not be available on terms that are favorable to us, if at all. If we raise additional funds through the issuance of equity or convertible debt securities, our stockholders' equity interest will be diluted and these securities might have rights, preferences and privileges senior to those of our current stockholders. We may also require the consent of our new lenders to raise additional funds through equity or debt financing. No assurance can be given that additional financing will be available or that, if available, such financing can be obtained on terms favorable to our stockholders and us.

As of June 27, 2025, we have cash of approximately $227.9 million in our foreign subsidiaries. It is not practicable to determine the tax liability that might be incurred if the undistributed earnings of these foreign subsidiaries were to be distributed. It is the Company's practice and intention to reinvest the earnings of its non-U.S. subsidiaries in those

------

<u>[**Table of Contents**](#i00a6705ed68349f3a776382b0e891bd7_7)</u>

operations, except for certain of its subsidiaries based in Singapore and China. There is no expected Singapore or U.S. tax liability on a distribution of the Singapore earnings. However, the Company has accrued taxes on the undistributed earnings of the China subsidiary in its financial statements as of June 27, 2025.

*Borrowing Arrangements* 

The following table summarizes our borrowings:

---

| | | |
|:---|:---|:---|
| | **June 27,<br>2025** | **June 27,<br>2025** |
| **(Dollars in millions)** | **Amount**  | **Weighted-**<br>**Average**<br>**Interest Rate**  |
| U.S. Term Loan | $484.5 | 7.6% |
| Debt issuance costs | (6.1) |  |
|  | $478.4 |  |

---

At June 27, 2025, the Company had an outstanding amount under the Term Loan of $484.5 million, gross of unamortized debt issuance costs of $6.1 million. As of June 27, 2025, the interest rate on the outstanding Term Loan was 7.6%.

As of June 27, 2025, the Company had $146.4 million, net of $3.6 million of outstanding letters of credit, available under this revolving credit facility. As of June 27, 2025, the Company was in compliance with the financial covenants contained within the Amended Credit Agreement.

The Company maintains credit agreements with a local bank in Czechia and with a financial institution in Israel, which provide for revolving credit facilities of up to 7.0 million euros (approximately $8.2 million) and $5.0 million, respectively. As of June 27, 2025, there were no borrowings outstanding under these facilities.

As of June 27, 2025, the Company's total bank debt was $478.4 million, net of unamortized debt issuance costs of $6.1 million. As of June 27, 2025, the Company had $146.4 million, $5.0 million, and 5.5 million euros (approximately $6.4 million) available to draw from its credit facilities in the U.S., Israel and Czechia, respectively.

See Note 6 - Borrowing Arrangements, of our Condensed Consolidated Financial Statements, included in Part 1 of this Form-10Q for additional information.

***Capital Expenditures***

Capital expenditures were $29.2 million during the six months ended June 27, 2025 and were primarily attributable to the capital invested in our manufacturing facilities worldwide. The Company anticipates that capital expenditures for the remainder of 2025 will be financed primarily through cash flow generated from operations and cash on hand.

***Contractual Obligations***

The Company had commitments to various third parties to purchase inventories totaling approximately $407.9 million as of June 27, 2025.

In conjunction with the sale of our products in the ordinary course of business, we provide standard indemnification against certain liabilities to our customers, which may include claims of losses by their own customers resulting out of property damages, bodily injuries or deaths, or infringement of intellectual property rights by our products. Our potential liability arising out of intellectual property infringement claims by any third party is generally uncapped. As of June 27, 2025, we have not incurred any significant costs to defend lawsuits or settle claims related to these indemnification arrangements. As a result, we believe the estimated fair value of these arrangements is minimal.

**ITEM 3. Quantitative and Qualitative Disclosures About Market Risk** 

There were no significant changes to our quantitative and qualitative disclosures about market risk during the period covered by this report. Refer to Part II, Item 7A. "Quantitative and Qualitative Disclosures about Market Risk" included in our Annual Report on Form 10-K for our fiscal year ended December 27, 2024, for a more complete discussion of the market risks we encounter.

**ITEM 4. Controls and Procedures** 

**Evaluation of Disclosure Controls and Procedures**

Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined in Rule 13a-15(e) under the Exchange Act. Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms and that such information is accumulated and communicated to management, including the chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure. Based upon this evaluation, our chief executive officer and our chief financial officer concluded the disclosure controls and procedures were not effective as of June 27, 2025, the end of the period covered by this Quarterly Report on Form 10-Q, due to material weaknesses in internal control over financial reporting described below.

Material Weaknesses in Internal Control Over Financial Reporting

As previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 27, 2024, the Company identified the following material weaknesses in our internal control over financial reporting that continue to exist as of June 27, 2025.

The Company did not design and maintain effective controls relating to the: (i) sufficiency of processes related to identifying and analyzing risks to the achievement of objectives across the Company, (ii) sufficiency of competent personnel to analyze risks of material misstatement and develop internal control activities to support the achievement of the Company's internal control objectives; and (iii) monitoring of control activities in accordance with established policies in a timely manner.

These material weaknesses contributed to the following additional material weaknesses:

(a) The Company did not design and maintain effective information technology ("IT") general controls for certain information systems that are relevant to the preparation of its consolidated financial statements. Specifically, for certain of the Fluid Solutions operating subsidiaries in the Products segment which have not been migrated to the Company's primary ERP system, the Company did not design and maintain (i) program change management controls to ensure that IT program and data changes are identified, tested, authorized and implemented appropriately, and (ii) user access controls to ensure appropriate segregation of duties and to adequately restrict user and privileged access to appropriate company personnel.

(b) The Company did not design and maintain effective controls for certain other international operating subsidiaries in the Products segment. Specifically, the Company did not design and maintain effective segregation of duties controls across various business processes, including journal entries.

The material weaknesses described above did not result in any material misstatements to annual or interim consolidated financial statements. However, these material weaknesses could result in misstatements of our consolidated financial statements that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

***Remediation Plan and Progress***

Management has been executing and remains committed to implementing measures designed to ensure that control deficiencies contributing to the material weaknesses are remediated, such that these controls are designed, implemented, and operating effectively.

In response to all material weaknesses, management has taken the following actions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• engaged an external advisor to assist with evaluating and documenting the design and operating effectiveness of internal controls and to assist with the remediation of deficiencies, as necessary;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• hired additional IT, accounting, and finance personnel to support our remediation efforts, including a Vice President of Internal Audit, as well as third-party resources with relevant expertise to augment our internal resources;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• formalized roles and responsibilities within the organization to establish ownership of workstreams to identify and analyze risks of material misstatement, develop internal control activities to support the achievement of the Company's internal control objectives, and monitor the effective performance of those control objectives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• performed an entity-wide risk assessment of information technology systems and business processes by operating subsidiary; and

------

<u>[**Table of Contents**](#i00a6705ed68349f3a776382b0e891bd7_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• assessed the specific training needs for newly hired and existing personnel and developed and delivered training programs designed to support our internal controls.

In response to the material weakness "(a)" management has taken the following actions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We have migrated the Fluid Solutions operating subsidiaries to our primary ERP system early in the third quarter of 2025, including the utilization of existing IT general controls of our primary ERP system leveraging standard user access controls to ensure appropriate segregation of duties that adequately restrict user access to our financial applications and data to appropriate company personnel.

In response to the material weakness "(b)" management has taken the following actions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the second quarter of 2025, we completed the design and implementation of controls over segregation of duties assessment to identify key conflicts, established policies and procedures to maintain effective segregation of duties, and identified and implemented mitigating controls for key conflicts identified for certain other international operating subsidiaries in the Products segment which have not been migrated to the Company's primary ERP system.

Management has made progress in addressing the previously identified material weaknesses, and the results of our testing indicate that the Company's control environment has improved since the material weaknesses were first identified. While we have made progress, the material weaknesses will not be considered remediated until we conclude all measures necessary to remediate the material weaknesses have been designed, implemented, and the applicable controls have operated for a sufficient period of time, and management has concluded, through testing, that these controls are designed and operating effectively. While Management believes that the aforementioned plans will remediate the material weaknesses, there is no assurance of the exact timing of the completion of the remediation.

***Changes in Internal Control Over Financial Reporting***

Except for the design and implementation of controls over segregation of duties in response to material weakness "(b)" described above, there were no changes in our internal control over financial reporting during the quarter ended June 27, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**PART II. OTHER INFORMATION** 

**ITEM 1. Legal Proceedings** 

From time to time, we are subject to various legal proceedings and claims, either asserted or unasserted, that arise in the ordinary course of business. Although the outcome of the various legal proceedings and claims cannot be predicted with certainty, we have not had a history of outcomes to date that have been material to our Condensed Consolidated Statement of Operations and do not believe that any of these proceedings or other claims will have a material adverse effect on our condensed consolidated financial condition or results of operations.

On June 7, 2024, UCT received a subpoena from the SEC related to the material weaknesses identified in our 2022 and 2023 Forms 10-K and the change of our independent auditors. On March 20, 2025, UCT received the official termination letter from the SEC, noting that the investigation has concluded with no enforcement action recommendation.

On March 24, 2025, a putative securities class action was filed in the United States District Court for the Northern District of California, captioned *Ofir Schweiger v. Ultra Clean Holdings, Inc.*, et al., (Case No. 3:25-cv-02768), against the Company and our former Chief Executive Officer, James Scholhamer, and our Chief Financial Officer, Sheri Savage. The lawsuit brings claims under Section 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder, alleging that the Company and certain of its officers have knowingly made materially misleading statements about demand in the Chinese market for the Company's products to artificially inflate the price of the Company's common stock, while knowing that the Company was experiencing softening demand. The action purports to be brought on behalf of those who purchased or otherwise acquired the Company's publicly traded securities between May 6, 2024 and February 24, 2025, and seeks unspecified damages and other relief. The case is still in its early stages. Management believes these claims to be meritless and intends to vigorously defend against them. There is no assurance that the Company will be successful in its defense or that insurance will be available or adequate to fund any settlement or judgment or the litigation costs. The Company cannot reasonably estimate any loss or range of loss that may arise from this case.
