  1. PROPOSAL 1: ELECTION OF DIRECTORS

    PROPOSAL 1: ELECTION OF DIRECTORS Our Amended and Restated Bylaws provide that our Board of Directors shall be elected at the annual meeting of our stockholders, and each director so elected shall hold office until such director’s successor is elected and qualified or until such director’s earlier death, resignation or removal. Our Board of Directors, at the recommendation of the Nominating, Environmental, Social and Corporate Governance Committee, has recommended for nomination the nominees for director named below. All of these nominees currently serve as our directors. Each nominee has consented to serve as a nominee, to serve as a director if elected, and to being named a nominee in this proxy statement. Barbara Scherer will not stand for reelection at the 2025 Annual Meeting of Stockholders. If a director nominee becomes unavailable before the election, your proxy authorizes the people named as proxies to vote for a replacement nominee if our Board of Directors names one. Our Amended and Restated Bylaws provide that a director nominee must receive a majority of the votes cast with respect to such nominee in uncontested director elections (i.e., the number of shares voted “for” a director nominee must exceed the number of shares voted “against” such nominee). Accordingly, abstentions and broker non-votes will have no effect on the outcome of this proposal. If an incumbent director nominee fails to receive a majority of the votes cast in an uncontested election, the director shall immediately tender his or her resignation to the Board. The Nominating, Environmental, Social and Corporate Governance Committee of the Board, or such other committee designated by the Board, shall make a recommendation to the Board as to whether to accept or reject the resignation of such incumbent director, or whether other action should be taken. The Board shall act on the resignation, taking into account the committee’s recommendation, and publicly disclose its decision regarding the resignation within 90 days following certification of the election results. If the Board accepts a director’s resignation, or if a nominee for director is not elected and the nominee is not an incumbent director, the remaining members of the Board may fill the resulting vacancy or may decrease the size of the Board.

  13. Consideration of Director Nominees

    Consideration of Director Nominees Director Qualifications. The Nominating, Environmental, Social and Corporate Governance Committee of the Board operates pursuant to a written charter establishes membership criteria for the Board and each committee of the Board and recommends to the Board individuals for membership on the Board and its committees. There is no fixed set of qualifications that must be satisfied before a candidate will be considered. Rather, candidates for director nominees are reviewed in the context of the current composition of our Board of Directors, our operating requirements and the interests of our stockholders. In conducting its assessment, the committee considers issues of judgment, diversity, age, skills, background, experience and such other factors as it deems appropriate given the needs of the Company and our Board of Directors. Although we do not have a formal policy with regard to the consideration of diversity, when identifying and selecting director nominees, the Nominating, Environmental, Social and Corporate Governance Committee also considers the impact a nominee would have in terms of broadening the range of professional experience, skills, backgrounds, viewpoints and areas of expertise represented on our Board of Directors. The Nominating, Environmental, Social and Corporate Governance Committee also considers the independence, financial literacy and financial expertise standards required by our committee charters and applicable laws, rules and regulations, and the ability of the candidate to devote the time and attention necessary to serve as a director and a committee member. Identifying and Evaluating Nominees for Director. In the event that vacancies are anticipated or otherwise arise, the Nominating, Environmental, Social and Corporate Governance Committee considers various potential candidates for director. Candidates may come to the attention of the Nominating, Environmental, Social and Corporate Governance Committee through current directors, professional search firms, stockholders or other persons. Candidates are evaluated at regular or special meetings of the Nominating, Environmental, Social and Corporate Governance Committee (or our independent directors) and may be considered at any point during the year. Stockholder Nominees. Candidates for director recommended by stockholders will be considered by the Nominating, Environmental, Social and Corporate Governance Committee. Such recommendations should include the candidate’s name, home and business contact information, detailed biographical data, relevant qualifications for membership on our Board of Directors, information regarding any relationships between the candidate and our Company within the last three years and a written indication by the recommended candidate of the candidate’s willingness to serve on our Board of Directors.

  31. Overview of Compensation Program and Philosophy

    | • | providing significant, long-term equity incentive opportunities in order to retain those individuals with the leadership abilities necessary for increasing long-term stockholder value while aligning the interests of our executive officers with those of our stockholders. |

  32. Process for Determining Executive Compensation

    Process for Determining Executive Compensation Each year, our Compensation and People Committee, together with our senior management team, establishes performance targets for short-term and long-term incentive plans that require the achievement of significant financial results. Each year, our Compensation and People Committee determines compensation by assessing prior year performance against these established financial targets, as well as other factors such as the compensation paid by comparable companies (which may include comparisons to companies in broad-based compensation surveys or, for fiscal 2024, our peer group), achievement of strategic objectives, improvements in market share and the professional development and potential of individual officers. Ultimately, the amount of compensation awarded to our executive officers is determined based on performance and what our Compensation and People Committee believes is in the best interests of our stockholders. The Compensation and People Committee meets with our Chief Executive Officer and other executives, including our Chief Human Resources Officer, as necessary, to obtain recommendations with respect to Company compensation programs, practices, and packages. The Chief Executive Officer, in consultation with our Chief Human Resources Officer, makes recommendations to the Compensation and People Committee on executive performance, base salary, annual bonus targets and equity compensation for the executive team and other employees, other than himself. Our Chief Human Resources Officer also meets directly with the Compensation and People Committee (including outside the presence of our Chief Executive Officer) to assist the Compensation and People Committee in its decision-making process, including its analysis of third-party industry surveys and other data on executive compensation. Although the Compensation and People Committee considers management’s recommendations with respect to executive compensation, the Compensation and People Committee makes all final decisions on executive compensation matters. Our Chief Executive Officer and Chief Human Resources Officer attend most of the Compensation and People Committee’s meetings, but the Compensation and People Committee also holds executive sessions not attended by any members of management or non-independent directors. The Compensation and People Committee deliberates and makes decisions with respect to performance and compensation without the Chief Executive Officer and the Company’s other executives present. The Compensation and People Committee has the ultimate authority to make decisions with respect to the compensation of our executive officers, but may, if it chooses, delegate some of its responsibilities to subcommittees. The Compensation and People Committee has not in the past delegated authority with respect to the compensation of executive officers. The Compensation and People Committee initially engaged Semler Brossy as its outside compensation consultant in 2019 to provide an independent review of the Company’s executive compensation program, including an analysis of both the competitive market and the design of our compensation programs. Semler Brossy continued to provide advice and recommended a course of action for fiscal year 2024. More specifically, Semler Brossy advised the Compensation and People Committee on the designation of peer group companies, evaluated the final list of peer companies approved by the Compensation and People Committee and provided competitive compensation data and analysis relating to the compensation of our Chief Executive Officer and our other executive officers. Semler Brossy also furnished the Compensation and People Committee with reports on peer company practices relating to the following matters: short-term and long-term compensation program design; equity compensation; retention value of current equity holdings; target incentive opportunities; and compensation trends. In addition, Semler Brossy assisted the Compensation and People Committee with its CEO pay ratio analysis and provided our Compensation and People Committee assistance in developing our Compensation Discussion and Analysis in this proxy statement. Semler Brossy attended meetings of the Compensation and People Committee regarding executive compensation and communicated with the chair of the Compensation and People Committee outside of meetings. The consultant reported to the Compensation and People Committee rather than to management, although the consultant met with management from time to time for purposes of gathering information on proposals that management made or may make to the Compensation and People Committee. The Compensation and People Committee has the authority to replace the compensation consultant or hire additional consultants at any time. Semler Brossy provided analyses and recommendations that inform the Compensation and People Committee’s decisions, but it did not decide or approve any compensation decisions. Except for the Company’s subscription to certain compensation survey data, Semler Brossy had not provided any services to the Company other than to the Compensation and People Committee and received compensation from the Company only for services provided to the Compensation and People Committee. Our Compensation and People Committee assessed the independence of Semler Brossy pursuant to SEC and Nasdaq rules and concluded that Semler Brossy is independent and that Semler Brossy’s work has not raised any conflict of interest. In October 2024, the Compensation and People Committee engaged FW Cook to be its compensation consultant on a go-forward basis. Since the date of engagement, FW Cook conducted executive and non-employee director market assessments, conducted a review of the Company’s executive compensation benchmarking peer group and consulted on executive compensation related trends, in all cases to support the compensation planning process for 2025. As part of the transition process, the Compensation and People Committee assessed the independence of FW Cook pursuant to SEC and Nasdaq rules and concluded that FW Cook is independent and that their work for the Compensation and People Committee does not raise any conflict of interest.

  36. Compensation Structure

    This Compensation Peer Group is not used for purposes of analyzing the Company’s stock price performance as compared to the Nasdaq Composite Index and the RDG Semiconductor Composite Index. For further information regarding the Company’s cumulative total and relative stockholder return, see our graph included in our Annual Report on Form 10-K for the year ended December 27, 2024. As discussed above, our Compensation and People Committee has a long-term practice of targeting the compensation levels of our executive officers at or around the median of the compensation of comparable officers at comparable companies, as derived from peer group data and broader composite survey data. Our Compensation and People Committee may vary from this target range for various elements of compensation depending on the executive officer’s job performance, skill set, level of responsibility, prior compensation, and business conditions, or for other reasons. Any significant variations of our fiscal 2024 pay decisions as compared to long-term targeted levels are further discussed below.

  37. Cash Compensation

    In fiscal 2024, the Compensation and People Committee determined to increase the base salary of our NEOs, ranging from 3.5% to 4.5%, as part of the Compensation and People Committee’s long-term goal of more closely aligning our NEOs’ base salary with the market and to recognize each of our NEOs’ performance in their respective roles. Our base salary levels were also set after considering the significance of the roles of these executives in our overall management for fiscal 2024 and the Compensation and People Committee’s determination of the correlation of their responsibilities with our overall corporate operating needs. Overall, the Compensation and People Committee determined that the base salary levels/increases were consistent with the Company’s overall compensation objectives and were appropriate to retain our executives at a point in time at which the Company had achieved strong results in fiscal 2024 Fiscal 2024 Cash Incentive Bonuses. On February 15, 2024, the Compensation and People Committee approved target incentive cash compensation for our executive officers for 2024 under our management bonus plan (the “Management Bonus Plan”). The Company’s executive officers were eligible to participate in the Management Bonus Plan, which provided for the opportunity to earn semi-annual and annual bonuses based on corporate and individual performance during the fiscal year. Bonuses under the Management Bonus Plan are based on each executive officer’s annual target cash incentive opportunity (established as a percentage of each executive officer’s base salary, referred to as the “Target Bonus”). For each executive officer, 85% of the cash bonus opportunity under the Management Bonus Plan can be earned from 0% to 200% of the Target Bonus based on performance of the Company against corporate goals and objectives as approved by the Compensation and People Committee for the applicable measurement period, 55% of which was based on financial and operating performance measured quarterly and paid out semi-annually, and 45% of which was based on annual corporate goals and objectives and paid out annually. In addition, for each executive officer, the remaining 15% of their cash bonus opportunity under the Management Bonus Plan can be earned from 0% to 100% of the Target Bonus based on their individual performance against individual goals approved by the Compensation and People Committee, measured and paid out annually. The Compensation and People Committee may increase or decrease bonuses calculated under the Management Bonus Plan at its discretion based on corporate or individual performance. Corporate goals and objectives under the Management Bonus Plan may include goals and objectives relating to operational performance (e.g., quality and delivery performance), growth, implementation of strategic programs, financial results as compared to the Company’s operating plan or other benchmarks, and human resource initiatives. Individual goals and objectives were tailored to each executive officer’s position and are designed to award performance based on the individual’s contribution to the Company’s growth, financial performance, structural organization and achievement of strategic initiatives. Target Bonus opportunities under the Management Bonus Plan are reviewed and approved on an annual basis for each named executive officer and established based on market data, role and level of responsibility and other individual factors specific to each executive officer. As discussed earlier, there were no changes to the target bonus percentages for any of the NEOs for fiscal 2024, which were as follows:

  38. Cash Compensation

    | | TARGET BONUS AS A PERCENTAGE OF BASE SALARY | | | Named Executive Officer | 2024 (%) | 2023 (%) | | James P. Scholhamer | 110 | 110 | | Sheri L. Savage | 85 | 85 | | Harjinder Bajwa(1) | 85 | — | | Christopher S. Cook | 60 | 60 | | Jeffrey L. McKibben | 60 | 60 |

  39. Cash Compensation

    Under the Management Bonus Plan, each executive officer’s annual incentive payout cannot exceed 185% of the executive officer’s Target Bonus over the applicable bonus period, without the approval of the Compensation and People Committee. At the beginning of each year, the Compensation and People Committee reviews and establishes (a) quantitative corporate goals for the first half of the year and the full year and (b) a combination of quantitative and qualitative individual performance goals for the full year. Then, in July of each year, the Compensation and People Committee reviews and establishes quantitative corporate goals for the second half of the year for the relevant portion of the cash incentive compensation. The original first half and annual corporate goals remain unchanged. The Compensation and People Committee utilizes this approach to find a reasonable balance between having an annual program but allowing for some flexibility to determine second half goals, in order to account for the current state of the business and the Company’s industry, including the changes in business outlook of the Company’s major customers. The Compensation and People Committee believe that the goals are rigorous yet attainable to drive overall Company performance and remain appropriate throughout the year when the sector is experiencing heightened levels of volatility. At the end of each performance period, the Compensation and People Committee reviews the performance against the pre-determined threshold, target, and maximum goals. For fiscal 2024, bonuses earned by our named executive officers under the Management Bonus Plan were as follows:

    | (1) The Management Bonus Plan for 2024 included semi-annual bonus opportunities based on Company financial and operational metrics, and a separate annual bonus opportunity based on additional annual Company financial and operational metrics and individual goals. |

  42. Cash Compensation

    | (2) Target incentive cash compensation was calculated based on the Target Bonus as a Percentage of Base Salary table above and the executive officer’s base salary for 2024 as set forth in the Base Salary table above. |

  43. Cash Compensation

    Quarterly achievement of corporate goals and objectives for our NEOs for 2024 was determined based on a corporate scorecard approved by the Compensation and People Committee at the time of the adoption of the Management Bonus Plan. These quarterly corporate goals and objectives were set based on key performance indicators for (i) quality and delivery performance as measured by customer scorecards, various internal quantitative quality and delivery metrics and qualitative assessments of customer satisfaction and (ii) financial performance, as measured by the Company’s actual revenue and free cash flow against the Company’s annual operating plan for 2024, which is updated for the second half of the year. Each of these goals was considered challenging but achievable at the time they were established. Annual achievement of corporate goals and objectives for our NEOs for 2024 was also determined based on a corporate scorecard approved by the Compensation and People Committee at the time of the adoption of the Management Bonus Plan. These annual corporate goals and objectives were based on key performance indicators for (i) the achievement of operational performance goals, including continuous improvement in quality, delivery, safety and customer perception of UCT’s operational performance, (ii) growth, measured by the Product division’s revenue growth as compared to the overall market for wafer fab equipment growth, and Services division’s revenue growth from integrated device manufacturers as compared to the overall market for wafer start growth, (iii) the achievement of key strategic programs for the Company in 2024, including to grow strategic engagement and design win with customers’ technology, product and operational roadmap, (iv) the achievement of key human capital strategic goals, including employee engagement to improve productivity, engagement and retention, (v) compliance and audit, work cross functionally to structure a robust IT General Controls/Segregation of Duty structure that will be used in 2025 Financial/Controls Audit, and (vi) financial performance, measured by revenue, operating margin and free cash flow against the Company’s annual operating plan for 2024, capital expense control and payment terms management. Annual achievement of individual goals and objectives for our NEOs for 2024 was determined based on an individual scorecard for each NEO approved by the Compensation and People Committee at the time of the adoption of the Management Bonus Plan. Each of these goals was considered challenging but achievable at the time they were established. The Compensation and People Committee determined that the above goals and objectives for the 2024 Management Bonus Plan were appropriate to drive successful execution of specific, near-term strategic objectives for the Company, enhance accountability, and continue to emphasize the Company’s financial performance during the fiscal year in the achievement of annual cash incentive bonuses, while at the same time balancing near-term financial performance with strategic and operational objectives that would support the Company’s long-term growth and long-term strategies. After each quarterly period of fiscal 2024, the Compensation and People Committee reviewed actual corporate performance against the quarterly corporate scorecards, and in February 2025, the Compensation and People Committee reviewed actual corporate performance for fiscal 2024 against the annual corporate scorecards. The Compensation and People Committee approved payouts under the Management Bonus Plan for each semi-annual period in fiscal 2024 and for the annual 2024 period consistent with the Company’s scorecard achievement. In February 2025, the Compensation and People Committee also reviewed each of our NEOs’ actual individual performance against the annual individual scorecards. Following this review, the Compensation and People Committee determined to award our Chief Executive Officer an annual individual bonus equal to 13% (out of 15%) of his Target Bonus based on his achievement of individual goals. The Compensation and People Committee determined to award our Chief Financial Officer an annual individual bonus equal to 13% (out of 15%) of her Target Bonus based on her achievement of individual goals. The Compensation and People Committee also determined to award our other NEOs additional annual individual bonuses ranging from 11% to 15% (out of 15%) based on their achievement of individual goals. Our Compensation and People Committee invests significant time determining the financial and non-financial targets for the Company’s Management Bonus Program. In general, management makes the initial recommendation for the financial and non-financial targets based upon the Company’s annual Board-approved operating plan and other strategic goals and objectives, as well as the bonus opportunity for each officer, and these recommendations are reviewed and discussed by the Compensation and People Committee and its advisors. The major factors used in setting one or more targets for a particular year are the results for the most recently completed year and the annual operating plan for the current year. Other factors considered may include general economic and market conditions. Overall, the Compensation and People Committee seeks to tie a significant proportion of cash compensation to performance, while factoring in the Company’s current and expected financial results given current and expected business conditions and the cyclical nature of the semiconductor equipment industry. The Compensation and People Committee also recognizes that the Management Bonus Plan provides increased cash payments to our executives if we achieve results above targets, providing our executives an opportunity to achieve higher cash compensation for performance above expectations. We intend for the performance goals to be challenging but achievable and to reflect strong corporate performance. Semi-annual bonuses under the Management Bonus Plan are calculated and paid on a semi-annual basis, subject to the employee’s continued service with the Company through the applicable payment date, which the Company believes to have a positive effect on employee morale.

  44. Equity Compensation

    Equity Compensation Our equity compensation program is intended to align the interests of our executive officers with those of our stockholders by creating a long-term incentive for our executive officers to maximize stockholder value. The equity compensation program also is designed to encourage our executive officers to remain employed with us in a very competitive labor market. The Compensation and People Committee regularly monitors the changes in the business environment in which we operate and periodically reviews changes to our equity compensation program to help us meet our goals, which include the achievement of long-term stockholder value. Types of Equity Awards. In fiscal 2024, consistent with recent years, we granted our NEOs a combination of time-based and performance-based restricted stock units, or RSUs and PSUs. Mix of Performance versus Time-based “Refresh” Grants. The mix of time-based and performance-based awards for grants made in April 2024 were generally consistent with 2023. In allocating equity awards between time-based and performance-based awards, the Compensation and People Committee considers each NEO’s level of responsibility, and the relationship between that NEO’s performance and our common share price. The Compensation and People Committee determined that 55% of the annual “refresh” equity awards that were granted to our Chief Executive Officer and 50% to our Chief Financial Officer, Chief Operating Officer and Chief Information Officer would consist of performance-based awards because their roles focus more on overall corporate performance than our other NEOs. Performance-Based Equity Design. The annual PSU award program was designed to consider multiple performance metrics over a three-year performance period. The vesting criterion for the PSU awards at the end of the three-year period is the Company’s total GAAP revenue growth as compared to its peers, subject to modifications based on the Company’s relative TSR performance as compared to its peers and the Company’s operating EBITDA margin as compared to its operating plan. The overall program has a cap of 200% of target. The Compensation and People Committee identified relative GAAP revenue growth as the primary metric for the new PSU design to focus attention on growing the business and driving behaviors to identify new avenues of growth, both organically and through strategic investments. Operating EBITDA margin remains a key priority for the business during a period of growth and relative TSR provides direct alignment with shareholders. The Compensation and People Committee selected the use of relative performance measurement for both revenue growth and TSR to ensure that the Company is gaining market share and outperforming peers and selected the use of absolute operating margin to provide better line of sight for the participating officers. The combination of the three metrics allows for a holistic review of overall company performance and focuses on overall top-line revenue growth while ensuring appropriate attention to operating margins and overall shareholder value. For the relative revenue growth and relative TSR performance metrics, the Compensation and People Committee identified a separate group of performance peers (that includes US and non-US companies) exposed to similar dynamics within the semiconductor industry, many of whom were also identified by several shareholders as key competitors. Semler Brossy conducted extensive back-testing to understand any correlation and directional alignment across these metrics when calibrating the peer group. This resulted in a peer group that included the following companies (collectively, the “Performance Peer Group”) with companies also included in the Compensation Peer Group identified with an (*):

  45. Equity Compensation

    | • Advanced Energy Industries (*) (AEIS) • Amkor (AMKR) • Applied Materials (AMAT) • ASM International (ASM) • Axcelis Technologies (ACLS) • Comet Holdings AG (COTN) • Entegris (ENTG) • FormFactor (*) (FORM) • Ichor (*) (ICHR) • KLA (KLAC) | • Kulicke and Soffa Industries (*) (KLIC) • Lam Research (LRCX) • MKS Instruments (*) ((MKSI) • Nova Measuring Instruments (NVMI) • Onto Innovation (*) (ONTO) • PDF Solutions (PDFS) • Photronics (*) (PLAB) • Teradyne (TER) • VAT Group AG (VACN) • Veeco Instruments (VECO) |

  46. Equity Compensation

    The relative revenue growth metric pays linearly out between 0% to 200% based on the Company’s relative performance compared to the Performance Peer Group from the three-year period starting January 1, 2024 through December 31, 2026 based on the following schedule (linear interpolation applies between performance levels):

  47. Equity Compensation

    | FY2024-FY2026 RELATIVE REVENUE POSITIONING | PAYOUT | | Below 30th %ile | 0% | | 30th %ile | 50% | | 50th %ile | 100% | | 80th %ile or above | 200% |

  48. Equity Compensation

    The absolute operating margin modifier can add or subtract 25% of target (not multiplicative) based on the Company’s operating EBITDA margin performance compared to each annual operating plan within the three-year period. The performance for each year in the three-year period will be averaged to determine the final result based on the following schedule (results are not linearly interpolated):

  49. Equity Compensation

    | FY2024-FY2026 AVERAGE OPERATING EBITDA MARGIN(1) | PAYOUT | | More than +200 basis points improvement | +25% | | Within -200 and 200 basis points improvement | 0% | | More than -200 basis point improvement | -25% |

  50. Equity Compensation

    | (1) See Appendix A for a reconciliation of GAAP to non-GAAP measures and for additional information about the non-GAAP measures we use in this proxy statement. |

  51. Equity Compensation

    The relative TSR modifier can add or subtract 25% of target (not multiplicative) based on the Company’s relative performance compared to the Performance Peer Group from the three-year period starting January 1, 2024 through December 31, 2026 based on the following schedule (results are not linearly interpolated):

  52. Equity Compensation

    | FY2024-FY2026 RELATIVE TSR RANK (INCLUDING ULTRA CLEAN) | PAYOUT | | Top Third (e.g., Rank 1 through 7) | +25% | | Middle Third (e.g., Rank 8 through 15) | 0% | | Bottom Third (e.g., Rank 16 through 22) | -25% |

  53. Equity Compensation

    In April 2024, the Compensation and People Committee granted the following long-term equity awards to our named executive officers:

  54. Equity Compensation

    | NAME | TIME- BASED (# SHARES) | PERFORMANCE- BASED (# SHARES) | TOTAL (# SHARES) | VALUE OF TARGET ANNUAL EQUITY GRANT ($)(1) | | James P. Scholhamer | 44,398 | 54,264 | 98,662 | 4,280,000 | | Sheri L. Savage | 17,289 | 17,289 | 34,578 | 1,500,000 | | Harjinder Bajwa(2) | 26,791 | 26,791 | 53,582 | 2,400,000 | | Christopher S. Cook | 15,560 | 5,186 | 20,746 | 900,000 | | Jeffrey L. McKibben | 8,068 | 8,068 | 16,136 | 700,000 |

  55. Equity Compensation

    | (1) The number of RSUs awarded to each of our executive officers was determined using a target dollar value, with the number of RSUs and PSUs granted to achieve such target dollar value based on the average closing price of the Company’s common stock during the 60 business days prior to the grant date. The grant date for these awards was April 26, 2024, and the average closing price was $43.38. |

  56. Equity Compensation

    | (2) New hire grants were awarded in June 2024. |

  57. Equity Compensation

    Size of FY2024 “Refresh.” The number of equity awards the Compensation and People Committee granted to each executive officer in 2024 was determined based on a variety of factors, including each individual executive’s job performance and his or her level of job responsibility. The Compensation and People Committee also considered the use of long-term equity awards as a means to retain and incentivize executives. The size of each equity award granted to a NEO in 2024 was determined based on target equity value rather than a target number of units. Accordingly, the number of equity awards granted was influenced by our stock price at the time the awards were granted. The number and target value of the long-term equity granted to Mr. Scholhamer in fiscal 2024 was set at a target annual equity grant value of approximately $4.28 million. The $4.28 million annual grant represented a 7% increase for Mr. Scholhamer compared to his $4 million fiscal 2023 equity grant, as part of the Compensation and People Committee’s long-term goal of more closely aligning our Chief Executive Officer’s equity awards with market levels, and also to recognize Mr. Scholhamer’s sustained strong performance and significant contributions to our organization. The Compensation and People Committee also considered its long-term goal of setting grants at a level consistent with the median provided to comparable officers by members of our peer group in determining grants for our non-CEO NEOs for fiscal 2024 (and in the case of new hires, at levels competitive for such executives in the employment market), while at the same time considering the relative positions of each NEO within our global organization and past grant practices. The 2024 equity awards granted in April 2024 for our NEOs shown in the table above were all generally within targeted levels, as adjusted to maintain internal equity for NEOs with similar levels of responsibility within our Company. The equity awards granted during fiscal 2024 to our NEOs are set forth in detail under “Grants of Plan-Based Awards” below. Promotion and New Hire Grants. The Compensation and People Committee’s policy has been to make promotion grants solely on a time-based vesting schedule to enhance retention. Grant Practices. New item 402(x) of Regulation S-K requires us to discuss our policies and practices on the timing of awards of options (or similar awards) in relation to the disclosure by us of material nonpublic information. While we do not current grant options (or similar awards), we have implemented procedures to regularize our equity award grant process, by making new hire grants and annual executive grants on the same day each month. The Compensation and People Committee has not granted, nor does it intend in the future to grant, equity compensation awards to executives in anticipation of the release of material nonpublic information that is likely to result in changes to the price of our common stock, such as a significant positive or negative earnings announcement. Because our equity awards typically vest over multiple years, we believe recipients are motivated to see our stock price rise in the long-term rather than benefit from an immediate but short-term increase in the price of our stock following a grant. 2022 PSU Grants. On April 29th, 2022, the Compensation and People Committee granted a mix of RSUs and PSUs to the executive officers. The PSUs granted in 2022 did not result in any issuance of shares to executive officers. Based on the relative revenue performance detailed above, these PSUs were achieved at 0%. The Compensation and People Committee then applied the -25% modifier based on relative TSR company performance and did not have any modifier applied due to the performance on Operating Margin vs. plan. The combination of those calculations resulted in a 0% achievement. For purposes of the payout calculation, companies in the 2022 performance peer group that were either acquired, taken private, or have gone bankrupt were positioned at the bottom of the group on both relative revenue and relative TSR performance.

  58. Other Benefit Plans

    Other Benefit Plans Deferred Compensation. We maintain a non-qualified deferred compensation plan, which allows eligible employees, including executive officers and directors, to voluntarily defer receipt of a portion of his/her salary and all or a portion of a bonus payment until the date or dates elected by the participant, thereby allowing the participating employee to defer taxation on such amounts. This plan gives highly compensated employees the opportunity to defer more compensation than they would otherwise be permitted to defer under a tax-qualified retirement plan, such as our 401(k) plan. We believe that deferred compensation is a competitive practice to enable us to attract and retain top talent. We do not make matching or other employer contributions to the deferred compensation plan because we believe the deferral opportunity is enough of a benefit on its own. Executive Perquisites. We offer limited perquisites to our executive officers. In addition to health care coverage that is generally available to our other employees, our executive officers are eligible for annual physical examinations more extensive than under the Company’s standard plans. Other Benefits. We also offer a number of other benefits to the executive officers pursuant to benefit programs that provide for broad-based employee participation. For example, our retirement plan is a tax-qualified 401(k) plan, which is a broad-based employee plan. Under the 401(k) plan, all participating employees (including executive officers) are eligible to receive limited matching contributions that are subject to vesting over time. The main objectives of our benefits programs are to give our employees access to quality healthcare, financial protection from unforeseen events, assistance in achieving retirement financial goals, enhanced health and productivity and to provide support for global workforce mobility, in full compliance with applicable legal requirements. These generally available benefits typically do not specifically factor into decisions regarding an individual executive’s total compensation or equity award package.

  59. Post-Termination Arrangements

    Post-Termination Arrangements Our post-termination arrangements with our NEOs are described in this proxy statement below. We believe the severance benefits under these agreements or policies are reasonable in amount and provide protection to key executive officers who would be likely to receive similar benefits from our competitors. The Compensation and People Committee reviews the potential costs and triggering events of employment and severance agreements and policies before approving them and will continue to consider appropriate and reasonable measures to encourage retention.

  60. Compensation Consultant

    Compensation Consultant The Compensation and People Committee determined to engage Semler Brossy with respect to fiscal 2024 executive officer and non-employee director compensation matters. Semler Brossy was retained by our Compensation and People Committee to provide an independent review of the Company’s executive compensation programs, including an analysis of both the competitive market and the design of the programs for 2024. In addition, during 2024, Semler Brossy assisted the Compensation and People Committee with its CEO pay ratio analysis. Semler Brossy also furnished the Compensation and People Committee with reports on peer company practices relating to the following matters: short-term and long-term compensation program design; equity compensation; retention value of current equity holdings; target incentive opportunities; and compensation trends. In October 2024, the Compensation and People Committee engaged FW Cook to be its compensation consultant on a go-forward basis. Since October 2024, FW Cook conducted executive and non-employee director market assessments, conducted a review of the Company’s executive compensation benchmarking peer group and consulted on executive compensation related trends, in all cases to support the compensation planning process for 2025. FW Cook also provided our Compensation and People Committee assistance in developing our Compensation Discussion and Analysis in this proxy statement.

  63. Summary Compensation Table

    | (1) Amounts shown do not reflect compensation received by the named executive officers. The amounts shown are the value for stock awards granted in the applicable fiscal year, based on the 60 trading days average price of our common stock preceding the grant date. The other valuation assumptions and the methodology used to determine such amounts are set forth in Note 1 of the Notes to our Consolidated Financial Statements included in our Form 10-K for the year ended December 27, 2024. |

  64. Summary Compensation Table

    The value the NEOs will ultimately receive from their 2024 PSUs will depend on the performance requirements and the market price of Common Stock at the end of the three-year performance cycle. In fiscal year 2024, PSUs were granted to all NEOs. The amounts reported were calculated in accordance with ASC 718 and reflect the grant date fair value at target (100%). The minimum number of PSUs that can be earned at the end of the three-year performance cycle is 0% and the maximum is 200%. The grant date fair value for the PSUs awarded to Mr. Scholhamer, Ms. Savage, Mr. Bajwa, Mr. Cook and Mr. McKibben at the maximum payout of 200% is $4,430,113, $1,411,474, $2,539,251, $423,385, and $658,672, respectively. The value the NEOs may receive from their RSUs will depend on whether the time-based vesting requirement is met and the market price of Common Stock on the vesting date. See Grants of Plan-Based Awards in Fiscal Year 2024 table for the number of RSUs granted in fiscal year 2024.

  90. Nonqualified Deferred Compensation

    Nonqualified Deferred Compensation We maintain a nonqualified deferred compensation plan, the Ultra Clean Holdings, Inc. 2004 Executive Deferred Compensation Plan (the “EDCP”), which allows eligible employees, including executive officers, and directors to voluntarily defer receipt of a portion of his/her salary and all or a portion of a bonus payment until the date or dates elected by the participant, thereby allowing the participating employee to defer taxation on such amounts. Amounts credited to the EDCP consist only of cash compensation that has been earned and payment of which has been deferred by the participant. The amounts deferred under the EDCP are credited with realized gains on investments and interest at market rates on cash balances. We do not make matching or other employer contributions to the EDCP. None of our named executive officers participated in the EDCP for fiscal 2024 and one of the named executive officers currently has an outstanding balance under the EDCP.

  91. CEO Pay Ratio

    CEO Pay Ratio As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are required to disclose the ratio of our median employee’s annual total compensation to the annual total compensation of our principal executive officer. During fiscal 2024, our principal executive officer was Mr. Scholhamer, our former Chief Executive Officer. For fiscal 2024, the combined annual total compensation for Mr. Scholhamer was $5,781,280, and for our median employee was $30,276, resulting in an estimated pay ratio of approximately 191:1. In accordance with the flexibility provided by Item 402(u) of Regulation S-K, we identified the median employee by calculating the aggregate amount of each employee’s 2024 base annual compensation (including overtime), bonus earned for 2024, and the value of commission or profit-sharing value received in 2024. We then ranked the compensation of our employees from lowest to highest and identified the median employee. This calculation was performed for all employees of the Company as of December 27, 2024 (excluding our CEO), whether employed on a full-time or part-time basis. For ease of administration, we did not include the accounting value of equity awards granted. Once we identified our median employee, we then calculated such employee’s annual total compensation for 2024 using the same methodology as that utilized for determining the annual total compensation of our NEOs in 2024 (as set forth in the 2024 Summary Compensation Table on page 40). Our CEO’s annual total compensation for 2024 for purposes of the Pay Ratio Rule is equal to the amount reported in the “Total” column in the 2024 Summary Compensation Table. The pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on our internal records and the methodology described above. Because the SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

  92. Pay Versus Performance

For the Company and peer group TSR, each year reflects what the cumulative value of $100 would be, including reinvestment of dividends, if such amount were invested on December 28, 2019. |

  103. Pay Versus Performance

    | (7) GAAP Revenue Growth is used as the Company selected metric and it is part of our annual incentive program and the primary component of our PSUs which measures relative revenue growth against a select group of performance peers. |

  104. Pay Versus Performance

    As highlighted in our CD&A, one of our primary principles of our compensation program is to ensure that there is a substantial portion of compensation of executive officer pay that is at-risk and is highly dependent on the Company’s short-term and long-term financial, operation, and stock price performance. For our executives, over 54% of their opportunity is tied to long-term equity incentives which will depend on our revenue growth and share price performance while roughly 19% of our executive pay is tied to annual financial and operational performance. We expect a stronger correlation to stock price performance and revenue growth through the combination of (a) having a significant portion of our pay tied to long-term incentives and (b) using PSUs linked to revenue growth and relative TSR as part of our annual long-term incentive mix. This relationship is highlighted in more detail in the next section. Relationship Between the Company’s Pay and Performance: Below are graphs showing the relationship of “compensation actually paid” (CAP) to our Chief Executive Officer and other named executive officers in 2020, 2021, 2022, 2023 and 2024 to (1) TSR of both the Company and the RDG Semiconductor Composite Index, (2) the Company’s net income and (3) the Company’s GAAP revenue growth. The following is a list of financial performance and non-financial performance measures, which in the Company’s assessment, represent the most important measures used by the Company to link compensation actually paid to the NEOs for 2024:
