notice you previously received.

Each share of common stock that you owned on the record date entitles you to one vote on each matter properly brought before the meeting. As of the record date, there were issued and outstanding 32,577,62445,537,032 shares of our common stock, $0.001 par value.

Holding Shares as a “Beneficial Owner” (or in “Street Name”)

Most stockholders are considered the “beneficial owners” of their shares, that is, they hold their shares through a broker, bank or nominee rather than directly in their own names. As summarized below, there are some distinctions between shares held of record and those owned beneficially or in “street name.”

Stockholder of Record.Record. If your shares are registered directly in your name with our transfer agent, you are considered the stockholder of record with respect to those shares. If you are a stockholder of record, we are sending paper copies of the proxy materials directly to you. As our stockholder of record, you have the right to grant your voting proxy directly to us by signing and mailing the enclosed proxy card or by voting on the Internet or telephone or in person at the annual meeting.


Beneficial Owner. Owner. If your shares are held in a stock brokerage account or by a bank or nominee, you are considered the beneficial owner of shares held in street name, and the proxy statement is being forwarded to you by or on behalf of your broker, bank or nominee (who is considered the stockholder of record with respect to those shares). As the beneficial

owner, you have the right to direct your broker, bank, or nominee how to vote by following the instructions you receive from your broker, bank or nominee. You are also invited to attend the annual meeting. However, since you are not the stockholder of record, you may not vote these shares in person at the annual meeting unless you request, complete and deliver a proxy from your broker, bank or nominee.

How to Vote

You may vote in person at the virtual meeting or by proxy.

Voting by Proxy. If you are a stockholder of record, you may vote by proxy over the Internet, by telephone or by mail if you complete and return the enclosed proxy card by following the instructions on the proxy card. If your shares are held in street name, you have the right to direct your broker, bank or nominee how to vote by following the instructions you receive from your broker, bank or nominee. The shares voted electronically, telephonically or represented by the proxy cards received, properly marked, dated, signed and not revoked, will be voted at the annual meeting. We recommend that you vote by proxy even if you plan to attend the meeting. You may change your vote at the meeting even if you have previously submitted a proxy.

Voting at the Annual Meeting. The method or timing of your vote will not limit your right to vote at the annual meeting if you attend the annual meeting and vote in person.meeting. However, if your shares are held in the name of a bank, broker or other nominee, you must obtain a legal proxy, executed in your favor, from the holder of record to be able to vote at the annual meeting. You should allow yourself enough time prior to the annual meeting to obtain this proxy from the holder of record.

How Proxies Work

This proxy statement is furnished in connection with the solicitation of proxies by us for use at the annual meeting and at any adjournment of that meeting. If you give us your proxy, you authorize us to vote your shares at the meeting in the manner you direct. You may vote for all, some or none of our director candidates. You may also vote for or against the other proposals, or you may abstain from voting.

If you give us your proxy but do not specify how your shares shall be voted on a particular matter, your shares will be voted:

FOR the election of each of the named nominees for director;

FOR the ratification of the appointment of Moss Adams LLP as our independent registered public accounting firm;

FOR the approval of the compensation of our named executive officers; and

with respect to any other matter that may come before the annual meeting, as recommended by our Board of Directors or otherwise in the proxies’ discretion.

Changing or Revoking Your Vote

You have the right to revoke your previously submitted proxy at any time before your proxy is exercised at the annual meeting.

If you are the stockholder of record, you may revoke your proxy by resubmitting your vote on a later date on the Internet or by telephone (only your latest Internet or telephone proxy submitted prior to the annual meeting will be counted), by signing and returning a new proxy card with a later date, by attending and voting at the annual meeting and voting in person or by giving written notice to our Secretary that you wish to revoke your previously submitted proxy.

If you hold shares beneficially in street name, you may revoke your proxy by submitting new voting instructions to your broker, bank or nominee by following the instructions they providedprovide you or, if you have obtained a legal proxy from your broker, bank or nominee giving you the right to vote your shares, by attending and voting at the annual meeting and voting in person.

meeting.

Note that for both stockholders of record and beneficial owners, attendance at the annual meeting will not cause your previously granted proxy to be revoked unless you specifically so request or vote in person at the annual meeting.

TABLE OF CONTENTS

Important Notice Regarding Delivery of Stockholder Documents

Only one proxy statement, annual report and set of accompanying materials, if applicable, are being delivered by us to multiple stockholders sharing an address, who have consented to receiving one set of such materials, until we receive contrary instructions from any such stockholders. We will deliver, promptly upon written or oral request, a separate copy of such materials to a stockholder at a shared address to which a single copy of such materials was delivered. A stockholder who wishes to receive a separate copy of the proxy statement and accompanying materials now or in the future, or stockholders sharing an address who are receiving multiple copies of the proxy statement and accompanying materials and wish to receive a single copy of such materials, should submit a request to Broadridge, c/o Householding Department, 51 Mercedes Way, Edgewood, NY 11717 or call 800-542-1061.

Attending in Person

Any stockholder of record may vote in person at the annual meeting of our stockholders. All meeting attendees will be required to present a valid, government-issued photo identification, such as a driver’s license or passport, in order to enter the meeting.

If you are a beneficial owner and your shares are held in the name of your broker, bank or nominee, you must bring a proxy from your broker, bank or nominee in order to vote in person.

Votes Needed to Hold the Meeting and Approve Proposals

In order to carry on the business of the annual meeting, stockholders entitled to cast a majority of the votes at a meeting of stockholders must be represented at the meeting, either in person or by proxy. In accordance with Delaware law, only votes cast “for” a matter constitute affirmative votes. A properly executed proxy marked “abstain” with respect to any matter will not be voted, although it will be counted for purposes of determining whether there is a quorum. Since abstentions will not be votes cast for a particular proposal, they will have the same effect as negative votes or votes against that proposal. Broker non-votes are also counted for the purpose of determining the presence of a quorum. Broker non-votes occur when shares held by a broker on behalf of a beneficial owner are not voted with respect to a particular proposal, which generally occurs when the broker has not received voting instructions from the beneficial owner and lacks the discretionary authority to vote the shares itself.

Election of Directors. Directors. Our Amended and Restated Bylaws provideprovides 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). 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.

Brokers do not have discretionary authority to vote shares without instructions from beneficial owners in the election of directors. Therefore, beneficial owners who are not stockholders of record and who want their votes to be counted in the election of directors must give voting instructions to their bank, broker or nominee before the date of the annual meeting.

Ratification of the appointment of our independent registered public accounting firm.firm. The affirmative vote of the holders of a majority of the shares of common stock present in person or represented by proxy and entitled to vote on the proposal will be required to ratify the appointment of our independent registered public accounting firm for the current fiscal year. We believe that the ratification of our independent registered public accounting firm is a routine proposal for which brokers may vote shares held on behalf of beneficial owners who have not given voting instructions with respect to that proposal.

Advisory vote on the compensation of our named executive officers.officers. The affirmative vote of the holders of a majority of the shares of common stock present in person or represented by proxy and entitled to vote on the proposal will be requiredsufficient to approve, by an advisory, non-binding vote, the compensation of our named executive officers for fiscal 2015.2021. The advisory vote on the compensation of our named executive officers, while held annually, is not considered a routine proposal; therefore, brokers lack the discretionary authority to vote shares without instructions from beneficial owners for this proposal.

Approval of any other matter properly submitted to the stockholders at the annual meeting generally will require the affirmative vote of the holders of a majority of the shares of common stock present in person or represented by proxy and entitled to vote on that matter.

Delinquent Section 16(a) Beneficial Ownership Reporting Compliance

Reports

Section 16(a) requires our directors, executive officers and beneficial holders of 10% or more of a registered class of our equity securities to file certain reports with the SEC regarding ownership of, and transactions in, our equity securities. Based solely on a review of Forms 3, 4 and 5 and amendments thereto furnished to us and written representations we received from our directors and officers required to file the reports, we believe that all of our directors, executive officers and beneficial holders of 10% or more of a registered class of our equity securities, filed, on a timely basis, all reports required by Section 16(a) of the Exchange Act for the year ended December 25, 2015.

One late Form 4 was filed for Ms. Brumm reporting shares withheld for payment of tax liability arising as a result of the partial settlement of restricted stock unit awards that vested on February 22, 2016.

Our Board of Directors recommends that you vote “FOR” each of the nominees to the Board of Directors set forth in this Proposal 1.
Structure of Board of Directors and Corporate Governance Information

Director Independence. Independence. We are required to comply with the director independence rules of the NASDAQNasdaq Stock Market (“NASDAQ”Nasdaq”) and the SEC. These rules require that the board of directors of a listed company be composed of a majority of independent directors and that the audit committee, compensation and people committee and nominating, environmental, social and corporate governance committee be composed solely of independent directors.

Our Board of Directors has determined that each of our directors and director nominees areis independent in accordance with applicable NASDAQNasdaq and SEC rules other than Messrs. Granger, Mezhvinsky andMr. Scholhamer. Accordingly, a majority of our current Board of Directors is independent as required by NASDAQNasdaq rules and, upon election of each of our director nominees at the 20162022 Annual Meeting of Stockholders, a majority of our Board of Directors will be independent as required by NASDAQNasdaq rules.

Director Responsibilities.Responsibilities. We are governed by our Board of Directors and its various committees that meet throughout the year. Our Board of Directors currently consists of seveneight directors. During 2015,2021, there were six meetings of our Board of Directors. We expect directors to attend and prepare for all meetings of the Board of Directors and the meetings of the committees on which they serve. Each of our directors attended more than 75% of the aggregate number of meetings of the Board of Directors and the committees on which he or she served during 2015.2021.

Our corporate governance guidelines allow for the flexibility to combine or separate the offices of chairmanChairman and the chief executive officerChief Executive Officer to best serve the interests of the Company and its stockholders.

Our Board of Directors believes our current board leadership structure to be an efficient and successful leadership model for the Company, promoting clear accountability and effective decision-making. The roles of our Chairman and Chief Executive Officer are separated to allow Mr. Scholhamer to develop and execute on our corporate strategy and focus on day-to-day operations and company performance. Our Board of Directors believes that our stockholders benefit from Mr. Granger has conducted,Granger’s service as Chairman due to his deep background and will conductexperience in our industry and his dutiesknowledge of our operations as non-executive Chairman effectively.our former Chief Executive Officer. Our Board of Directors recognizes that a different leadership model may be warranted under different circumstances. Accordingly, our Board of Directors periodically reviews its leadership structure.

The Board also continually reviews the need for effective independent oversight. Each member of each of our Board of Director’s standing committees is an independent director, and each independent director is actively involved in independent oversight. Our independent directors meet in executive session during each regularly scheduled quarterly meeting of our Board of Directors and periodically evaluate both our Chairman and our Chief Executive Officer.Officer as well as Board and committee performance. All directors have unrestricted access to management at all times and frequently communicate with the Chairman, the Chief Executive Officer and other members of management on a variety of topics. Given the above factors, our Board of Directors has historically determined that our leadership structure was appropriate and has not deemed it necessary to appoint an independent lead director. However, our Board of Directors will continue to periodically consider appointing one of our independent directors as our lead independent director.

 • We are committed to contributing to the communities in which we operate and support our employees who participate in local events through the investment of time and resources.
Corporate Governance

Sound governance and strong leadership are key to delivering sustained value to our stakeholders. To succeed, we must safeguard and retain the trust of employees, partners, customers, investors and the communities in which we work and live.
As stewards of the company, our Board of Directors provides guidance and oversight and ensures that we maintain our high ethical standards. Effective corporate governance requires achieving the right mix of experience, background and diversity in perspectives; this is particularly important in a complex and highly technical business like ours. For more information on board diversity, please see page 10.
We benefit from a highly engaged and informed Board of Directors. Our board composition complies with Nasdaq and Securities and Exchange Commission rules regarding director independence and meets the two California board diversity requirements regarding women and under-represented groups.
Given the importance of ESG considerations, in 2021 UCT established that two of our three board committees would share oversight responsibility for ESG:
 • The Nominating, Environmental, Social and Corporate Governance Committee (formerly the Nominating and Corporate Governance Committee) provides oversight and guidance for ESG matters focusing on environmental and governance areas.
 • The Compensation and People Committee (formerly the Compensation Committee) provides oversight and guidance for the social component of ESG, including talent and career development, employee retention, promotion of diversity and inclusion and other people-related matters.

Consideration of Director Nominees

Director Qualifications.Qualifications. The Nominating, Environmental, Social and Corporate Governance Committee of the Board operates pursuant to a written charter and 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 increasing the diversity of our Board of Directors with respect to professional experience, skills, backgrounds, viewpoints and areas of expertise. 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.

In the event that vacancies are anticipated or otherwise arise, the Nominating, Environmental, Social and Corporate Governance Committee (or, if the Nominating and Corporate Governance Committee is not comprised solely of independent directors, our independent directors) considers various potential candidates for director.

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.Nominees.

Stock Ownership Guidelines; Policy againstAgainst Hedging Transactions and Pledges

The guidelines provide that each director should hold at least 10,0003X annual cash compensation shares of our common stock, and that each director be allowed three years from the date such director joined our Board of Directors to accumulate such number of shares of our common stock. All of our directors are currently in compliance with our stock ownership guidelines.

The Board of Directors has also adopted stock ownership guidelines for our Chief Executive Officer. The policy was amended in February 2020 to provide that our Chief Executive Officer should hold common stock with a value at least 3X his or her base salary, and that he or she be allowed three years from the date such person becomes our Chief Executive Officer to accumulate such number of shares of our common stock. The amendment to the policy was intended to bring it in line with more contemporary governance and peer practices. Our Chief Executive Officer is currently in compliance with our stock ownership guidelines.
The Company’s Insider Trading Policy, which can be found on our website, provides that our securities shall not be made subject to hedge transactions or puts and calls. The Insider Trading Policy further prohibits any pledges of our securities by our directors and executive officers.

Related Person Transaction Policy.Policy. Our written Related Person Transaction Policy requires our Board of Directors or the Nominating, Environmental, Social and Corporate Governance Committee to review and approve all related person transactions. Our directors and officers are required to promptly notify our Chief Compliance Officer (currently our General Counsel) of any transaction which potentially involves a related person. Our Board of Directors or the Nominating, Environmental, Social and Corporate Governance Committee then considers all relevant facts and circumstances, including without limitation the commercial reasonableness of the terms of the transaction, the benefit and perceived benefit, or lack thereof, to the Company, opportunity costs of alternate transactions, the materiality and character of the related person’s direct or indirect interest, and the actual or apparent conflict of interest of the related person. Our Board of Directors or the Nominating, Environmental, Social and Corporate Governance Committee will not approve or ratify a related person transaction unless it has determined that, upon consideration of all relevant information, the transaction is in, or not inconsistent with, the best interests of the Company and its stockholders.
Other than as disclosed above, since December 25, 2020, we have not entered into any transactions, nor are there any currently proposed transactions, between us and a related party where the amount involved exceeds, or would exceed, $120,000, and in which any related person had or will have a direct or indirect material interest.

The Audit Committee may delegate its authority to pre-approve services to one or more Audit Committee members; provided that such designees present any such approvals to the full Audit Committee at the next Audit Committee meeting.

All services described above were pre-approved in accordance with the Audit Committee’s pre-approval policies.

Dismissal of Deloitte & Touche

During fiscal 2014, Deloitte & Touche served as our independent auditors and also provided tax services. On March 30, 2015, we dismissed Deloitte & Touche as our independent registered public accountant. We continued to employ Deloitte & Touche for tax advice.

The report of Deloitte & Touche on our consolidated financial statements for the fiscal years ended December 26, 2014 and December 27, 2013 did not contain any adverse opinion or disclaimer of opinion, and was not qualified or modified as to uncertainty, audit scope or accounting principles.

As it relates to the fiscal years ended December 26, 2014 and December 27, 2013, and through March 30, 2015, the effective date of Deloitte & Touche’s dismissal, (i) there were no disagreements (as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) between the company and Deloitte & Touche on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of Deloitte & Touche would have caused Deloitte & Touche to make reference to the subject matter of the disagreement in connection with its report, and (ii) there were no “reportable events” (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).

Fiscal 2021 Performance and Compensation Highlights
Despite the operational challenges associated with the pandemic-induced supply chain disruptions, we were able to deliver strong financial and market performance and maintain the design of our incentive programs.
Performance Highlights:
Achieved record revenue of $2.1 billion in 2021, an increase of 50% year-over-year.
Non-GAAP operating margin was 12.2% in 2021, compared to 11.3% in 2020.
Recorded the highest EPS in the company’s history, at $4.80 per diluted share compared to $2.80 in 2020.
Added process instrumentation and flow control systems to our current suite of offering by acquiring Ham-Let.
Strengthened our balance sheet in fiscal 2021 by completing an underwritten public offering of 3.7 million shares of our common stock for net proceeds of $192.8 million. As of December 31, 2021, UCT had $446.5 million in cash and cash equivalents.
Opened a new manufacturing facility in Malaysia that saw initial shipments to customers in September 2021.
Intel awarded us with “Supplier Continuous Quality Improvement Program Award” for our exemplary efforts to ensure uninterrupted supply and helping Intel meet customer needs while keeping our employees and communities safe, and invited us to partner with Intel on their massive expansion plans in Ohio.
UCT’s stock price increased by approximately 84% in 2021, outperforming the S&P 500 Index, Dow Jones Industrial Average and the Nasdaq 100 Index.
Compensation Highlights:
Our annual incentive outcomes for FY2021 were paid above target based on the strong performance results identified above. On average the NEOs received annual incentive outcomes of 137% of target. We did not have any performance restricted stock (“PSU”) incentive payouts for the FY2021 performance year given our shift from a one-year to a three-year design. Our next PSU payout will occur following the FY2023 performance year.
We made modest increases to target cash compensation, primarily through base salary increases, for our non-CEO NEOs ranging from 2% to 14%. We increased target cash compensation 14% for our CEO, through a base salary increase and target incentive opportunity increase to 110% of base salary, to bring him closer to competitive market levels after being below the market midrange in the past.
Equity grant opportunities, and subsequently target total pay opportunities (defined as base salary plus target annual incentive plus target equity grant) for all non-CEO NEOs stayed largely flat, and increased for our CEO by 21%, to similarly account for being below the market midrange and seeking to achieve parity with internal peers.
We continued to rely on performance-based equity as part of our long-term incentive program with a 55% mix for our CEO, 50% mix for CFO and COO and 25% for other NEOs.
25

TABLE OF CONTENTS

In 2021, we implemented a new PSU program to align with our business strategy by extending to a three-year performance period (FY2021 through FY2023) and using different metrics (relative revenue growth, operating EBITDA margin, relative total shareholder return) to better align the long term interests of our NEOs with those of our stockholders. The results of this award will only be determined after FY2023. To assist in the transition from a one-year performance period with ratable vesting to a three-year performance period with 100% cliff vesting we delivered a one-time time-vesting transition grant that vests over two years to help bridge the vesting gap that would occur in FY2022 and FY2023 for each of the NEOs.
Governance and Executive Pay Policies and Practices
The Company is committed to responsible executive compensation and governance practices that support our business and talent strategies to compete in the semiconductor industry while also aligning with prevailing governance practices.

Overview of Compensation Program and Philosophy

Our

As a general principle, the Company seeks to tie executive compensation program is intended to meetclosely with the Company’s performance. When assessing our compensation programs, our Compensation and People Committee relies on three principal long-term objectives:

guiding principles:
1.
1.attract,Attract, reward, and retain executive officers and other key employees;employees to help drive our business forward. More specifically, we compete for key talent with other companies in the semiconductor sector, and the competition is high. Further, we are in regular talent competition with other technology companies outside of the semiconductor sector, which puts upward pressure on pay opportunities – particularly long-term, equity incentive values.

2.
2.motivateMotivate key employees to achieve short-termgoals using individual performance goals combined with a balanced scorecard approach at the corporate, business unit and long-term corporate goalsoperational levels that enhance stockholder value;value. These corporate goals track with our longer-term objective of profitable growth and market share gains. Our corporate goals also addressed the integration of newly-acquired businesses, including the integration of key talent.

3.
3.promotePromote pay for performance, internal compensation equity and external competitiveness.

To meet these objectives, we have historically adopted the following overridinglong-term compensation policies:

Pay compensation that is competitive with the practices of our peer group ofsimilarly situated electronics manufacturing services (EMS) companies and the practices of similar companies noted in industry surveys; and

Pay for performance by:

offering annual short-term cash incentivesincentive opportunities upon achievement of performance goals we consider challenging but achievable; and

providing significant, long-term incentives in the form of stock options and other 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.

26

TABLE OF CONTENTS

Our Compensation and People Committee considers these policies in determining the appropriate allocation of long-term compensation, base salaries, annual bonuscash incentive compensation, long-term equity-based compensation and other benefits. Other considerations include our business objectives and environment, fiduciary and corporate responsibilities (including internal compensation equity considerations and affordability), competitive practices and trends, regulatory requirements, and regulatory requirements.the mitigation of risks associated with these policies. Like most companies, we use a combination of fixed and variable compensation programs to reward and incentivize strong performance, as well as to align the interests of our executive officers with those of our stockholders. In determining the particular elements of compensation that will be used to implement our overall compensation policies, the Compensation and People Committee takes into consideration a number of factors related to corporate and individual performance, as further described below, as well as competitive practices among our peer groupgroup.
Our Board of Directors and Compensation and People Committee have a long-standing practice of generally targeting compensation at or around the practicesmidrange of similarcomparable companies notedfor each element of our compensation program. The Compensation and People Committee believes that targeting overall, and each element of, compensation at or around the midrange of peer compensation will enable us to remain competitive in industry surveys.

Fiscal 2015 Key Considerations

Similarattracting and retaining qualified executive officers while avoiding paying amounts in excess of what we believe is necessary to fiscal 2015,attract and as discussed further below under “—retain such executive officers. Our Compensation and People Committee also retains the discretion to target compensation for specific individuals based on a variety of additional factors, including Company and individual performance.

Process for Determining Executive Compensation” we did not benchmark
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 of our named executive officerspaid by comparable companies (which may include comparisons to companies in broad-based compensation surveys or, for fiscal 2015 on an executive-by-executive basis against2021, our peer group. In addition, the Compensation Committee determined not to engage an independent compensation consultant to review the competitiveness and structuregroup), achievement of the Company’s 2015 cash and equity incentive programs or to provide the Compensation Committee with recommendations regarding changes to such plansstrategic objectives, improvements in connection with the Compensation Committee’s decisions on executive compensation for fiscal 2015. In making this determination, the Compensation Committee considered that it engaged an independent compensation consultant for such purpose in 2013. Moreover, the Compensation Committee utilized data from industry surveys on executive compensation to assist it in its determination of executive compensation for fiscal 2015.

Our fiscal 2015 compensation decisions, on an aggregate basis, primarily reflected the state of our business (and in particular, the state of the semiconductor industry), ourmarket share price, the state of the global economy and the demand for our products inprofessional development and potential of individual officers. Ultimately, the industries we served during fiscal 2015. Our sales were $469.1 million for fiscal 2015, representing a decreaseamount of 8.7% compared to $514.0 million in sales for fiscal 2014. Our sales for fiscal 2014, however, represented an increase 15.8% compared to $444.0 million in sales for fiscal 2013. Our

gross profit also decreased 2.9% in fiscal 2015 compared to fiscal 2014, but increased 8.6% in fiscal 2014 compared to fiscal 2013. Our average closing stock price was $6.79, $9.94 and $6.86 in fiscal 2015, 2014 and 2013, respectively, and was $9.92 at the time compensation decisions were made in February 2015 for fiscal 2015 compensation. Moreover, at the time compensation decisions were made in February 2015 for fiscal 2015 compensation, while our stock price was at a relatively high level as compared to the prior year average closing stock price, the Company was beginning to see some softness in the overall semiconductor equipment market, which it expected to continue over fiscal 2015. Overall, our Compensation Committee set target total compensation at levels relatively consistent with prior years, with actual compensation impacted by our relatively high grant date stock price for 2015, and operating results that reflected relatively challenging market conditions.

On an individual basis, our fiscal 2015 compensation decisions primarily reflected the importance of our top executives (primarily our chief executive officer and our president and chief financial officer) to our business and their roles in guiding the Company’s operations through challenging conditions for fiscal 2015. Moreover, compensation decisions for our chief executive officer and our president and chief financial officer were guided by their primary roles in our strategic acquisition activity, which resulted in two successful, significant acquisitions during fiscal 2015 (Marchi Thermal Systems Inc. and Miconex s.r.o.). The Compensation Committee considers these executives, particularly our chief executive officer and president and chief financial officer, to be our primary strategic decision makers and primarily responsible for our overall performance. In addition, we hired Mr. Scholhamer in January 2015 to replace Mr. Granger as our chief executive officer. Accordingly, Mr. Scholhamer’s compensation for 2015 was approved by the Compensation Committee based on negotiation with Mr. Scholhamer. Pursuant to Mr. Scholhamer’s offer letter approved by the Compensation Committee, we agreed to pay Mr. Scholhamer an annual base salary of $410,000, with an annual target bonus equal to 100% of his base salary, and to grant him an initial award of 200,000 restricted stock units that vest in four equal installments on each anniversary of the grant date, subject to the terms and conditions of our Stock Incentive Plan. Mr. Scholhamer is also eligible for certain severance and change in control benefits, as described under “—Post-Termination Arrangements” below.

Consistent with prior years, each of our named executive officers were eligible for increased cash incentive compensation and earned performance-based equity awards based on our results of operations, thus tying compensation to our performance. The Compensation Committee also considers that the valueawarded to our executive officers of their long-term equity incentive awards increases withis determined based on performance and what our stock price, providing our executives with further opportunity to increase the value of the compensation they ultimately realize, while aligning their incentives more closely with stockholder value.

Stockholder Votes

At our 2015 annual meeting of stockholders, the stockholders approved our non-binding advisory vote on our fiscal 2014 executive compensation program (“say-on-pay”). After considering our say-on-pay voting resultsCompensation and other factors addressedPeople Committee believes is in the subsequent discussion, thebest interests of our stockholders.

The Compensation Committee determined not to make changes to our executive compensation policies and practices as a result of the vote. At our fiscal 2011 annual meeting of stockholders, a majority of the stockholders voted to have the non-binding say-on-pay advisory vote appear annually in our proxy statement. Our Board of Directors considered the results of the vote and agreed with the results. Therefore, we are including the non-binding say-on-pay advisory vote on our executive compensation in this year’s proxy, and will have annual votes at least until the next stockholder vote on frequency. Executive compensation decisions for fiscal 2015 and other details are discussed below in this compensation discussion and analysis.

Process for Determining Executive Compensation

The CompensationPeople Committee meets with our chief executive officerChief Executive Officer and other executives, including our Senior Vice President of Human Resources, as necessary, to obtain recommendations with respect to Company compensation programs, practices and packages. The chief executive officerChief Executive Officer, in consultation with our Senior Vice President of Human Resources, develops recommendations that he 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 Senior Vice President of Human Resources 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 broad-based data from 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.

The chief executive officer attends

Our Chief Executive Officer and Senior Vice President of Human Resources 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 officerChief 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 has delegatedinitially engaged Semler Brossy as its outside compensation consultant in 2019 to provide an independent review of the chiefCompany’s executive officercompensation program, including an analysis of both the authoritycompetitive market and the design of our compensation programs.

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.

Semler Brossy attended meetings of the Compensation and People Committee regarding executive compensation and also communicated with the chair of the Compensation and People Committee outside of meetings. The consultant reported to the 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 Committee also periodically seeks input from independent compensation consultants prior to making determinations on executive compensation, though no such consultant was engaged for such purpose with respect to fiscal 2015 compensation. The Compensationand People Committee has the sole authority to retainreplace the compensation consultant or hire additional consultants at any time.

Semler Brossy provides analyses and terminaterecommendations that inform the Compensation and People Committee’s decisions, but it does not decide or approve any compensation decisions. Except for the Company’s subscription to certain broad-based compensation survey data, Semler Brossy has not provided any services to the Company other than to the Compensation and People Committee and receives 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 legal, financial, accounting or other advisors as it determines necessary to carry out its duties, without conferring with or obtaining the approvaland that Semler Brossy’s work has not raised any conflict of management or the full Board of Directors, including the sole authority to approve the fees and other retention terms of any such firm.

Elements of Compensation

Structure

The following are the primary elements of our executive compensation program:

(i)
base salary;

(ii)
annual performance-based cash incentive opportunities;

(iii)
(iii)annual long-term incentives through equity awards;incentive awards (both time-based and performance-based); and

(iv)
retirement and welfare benefit plans, including a deferred compensation plan, a 401(k) plan, limited executive perquisites and other benefit programs generally available to all employees.

Pay Mix.We have selected thesethe foregoing compensation elements because each is considered useful and/or necessary to meet one or more of the principal objectives of our compensation policy. For example, base salary and bonuscash incentive target percentages are set with the goal of attracting employees and adequately compensating and rewarding them for their individual performance, level of responsibility, time spent with the Companyexperience and the Company’s annual financial results, while our equity compensation programs are geared toward providing long-term incentives and rewards for the achievement of long-term business objectives and retaining key talent. We believe that these elements of compensation, when combined, are effective, and will continue to be effective, in achieving the objectives of our compensation program.

The charts below depict the allocation of fixed versus “at-risk” pay for the total target compensation for our NEOs in 2021:


Note: Figures include annualized base salary, target bonus, and grant date fair value of 2021 equity awards; excludes one-time transition grant.
The Compensation and People Committee reviews base salary, cash incentive programs and long-term incentive programs on at least an annual basis. Other programs are reviewed from time to time to ensure that benefit levels remain competitive but are not included in the annual determination of an executive’s compensation package. In setting compensation levels for a particular executive, the Compensation and People Committee takes into consideration the proposed compensation package as a whole and each element individually, as well as the executive’s past and expected future contributions to our business.

To achievePeople Committee believes that this our goal has been to allocate total compensation such that cash compensation (including base pay and annual bonus) falls between the 25th and 50th percentile among the peer group, and time and performance-based equity awards, whichapproach will yield increases in stockholder value, provide our executives with long-term incentives, fall between the 50th and 75th percentile of the peer group, consistent with our pay-for-performance objectives and focusing on creation of long-term stockholder value. Notwithstanding these long-term compensation objectives, the Compensation Committee considers uncertainty in the macroeconomy and cyclicality in the industries we serve, among other factors, in determining compensation packagesan appropriate reward for our executive officers, and reduce the risk of loss of executive officers to competitors.

While each element of our compensation program is intended to motivate and encourage employees at all levels to drive performance and achieve superior results for our stockholders, each element is weighted differently for each of our NEOs based on the employee’s position and ability to impact our financial results. In general, the percentage of at-risk pay, or pay based on the performance of the executive against corporate or individual goals, or that is based on the performance of our trading price, increases with job responsibility. This balance is intended to offer an opportunity for gain in recent years, these considerations havethe event of successful performance, matched with the prospect of less compensation when performance falls short of established financial and/or stockholder return targets.
Compensation Levels and Market Competitiveness. Overall compensation targets for executive officers are determined based on one or more of the following factors: the individual’s duties and responsibilities within our global Company; the individual’s experience and expertise; the compensation levels for the individual’s peers within our Company; compensation levels for similar positions in our industry or in the technology industry more generally; performance of the individual and our Company as a whole; and the levels of compensation necessary to recruit new executive officers. For fiscal 2021, our Compensation and People Committee reviewed the compensation of our executive officers and compared it with both that of our 2021 peer group and broader, composite global market survey data from the Radford Global Technology Survey.
For purposes of fiscal 2021 compensation decisions, Semler Brossy advised the Compensation and People Committee in October 2020 (based on publicly available data at such time) on the designation of peer group companies, using the following criteria: companies in the semiconductor and semiconductor equipment sectors and electronic manufacturing services and electronic equipment and instruments industries, companies with comparable revenues for the trailing 12 months and market capitalization to ours, and other companies selected by shareholder advisory services, as well as other qualitative factors. For the 2021 peer group, the median revenue and market capitalization as of October 2020 was $850 million and $1,507 million, respectively, versus $1,206 million and $906 million, respectively, for the Company. To develop a competitive market composite for our NEOs, Semler Brossy weighted composite market survey data, derived from both peer survey and general technology industry survey data, equally with named peer proxy data.
This resulted in compensationa peer group that included companies which, along with the broader survey data discussed above, were used for assessing our competitive market positioning in 2021 (collectively, the “Compensation Peer Group”) as set forth below:

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 responsibilities, prior compensation and business conditions, or for other reasons. Any significant variations of our fiscal 2021 pay decisions as compared to long-term targeted levels are further discussed below.

Such adjustments may be based on factors such as jobthe overall performance of our Company, new roles and responsibilities skill set, prior experience,assumed by the executive’s time in his or her position and/or with the Company, internal consistency regarding pay levels for similar positions or skill levels within the Company, and external pressures to attract and retain talent.

The Compensation and People Committee also takes into account the cyclical nature of our business (which results from the industries we serve (in particular the semiconductor industry) being highly cyclical, with recurring periods of over-supply of products) and the state of our industry and the economy in general.

Base Salaries. However, there is no specific weighting applied to any one factor in setting the level of base salary, and the process ultimately relies on the subjective exercise of our Compensation and People Committee’s judgment. Although salaries were targeted at or around the midrange of our Compensation Peer Group for fiscal 2021, our Compensation and People Committee also took into account historical compensation, internal parity with other executives, potential as a key contributor, and special recruiting and retention situations. The 2021 base salaries for our NEOs shown in the table below were generally within targeted levels.

In February of 2021, our Compensation and People Committee approved base salary increases for our NEOs as set forth in the table below:

In fiscal 2015,2021, the Compensation and People Committee determined to increase the base salary of our new chief executive officerChief Executive Officer by 8.3% to be $410,000 (which was prorated for 2015 based on$650,000, as part of the Compensation and People Committee’s long-term goal of more closely aligning our Chief Executive Officer’s base salary with the market, and also to recognize Mr. Scholhamer’s strong performance in the role of Chief Executive Officer and his start date), based on negotiation with Mr. Scholhamer. In addition, in March 2015, in connection with his promotionsignificant contributions to our presidentorganization.
The Compensation and chief executive officer, the CompensationPeople Committee also determined to increase the base salaries of Ms. Savage, Mr. Eichler’sChinnasami, Mr. Bentinck and Mr. Williams by between 2.4% and 13.5% to more closely align their base salaries with market levels, consistent with the Compensation and People Committee’s long-term compensation philosophy.
Our base salary to $370,000 (which was prorated for 2015 based on the effective date of his promotion), representing an increase of approximately 5.4% as compared to the level of his base salary in fiscal 2014. These levels were also set after considering the significance of the roles of these executives in our overall management for fiscal 20152021 and the Compensation and People Committee’s determination of the correlation of their responsibilities with our overall corporate operating performance. For the remainder of our named executive officers,Overall, the Compensation Committee determined to increase base salaries modestly by approximately 3% to 5%. While the Compensation Committee did not benchmark base salaries against a peer group for fiscal 2015, in determining to increase base salaries for fiscal 2015, the Compensation Committee considered industry survey data on executive compensation for similarly situated executives. Overall, the Compensationand People Committee determined that the base salary levels/increases were consistent with the Company’s overall compensation objectives and appropriate to retain our executives at a point in time at which the Company had positiveachieved strong results forin fiscal 2014 but was beginning to see some softness in the semiconductor equipment industry over the next several quarters.

year. Bonuses under the Management Bonus Plan are calculated and paidbased on a quarterly basis, which we believe to have a positive effect on employee morale. Each quarter, we calculate the total available pool ofeach executive officer’s annual target cash incentive bonuses using the “Percentage of Operating Income Distributed as Cash Incentive Compensation” as discussed above. For the four quarters of fiscal 2015, our aggregate quarterly bonuses were paid based on the following:

Once the available pool is determined for a given fiscal quarter as described above, the pool is then allocated among the participants in the plan, including our participating named executive officers, in accordance with each individual participant’s target bonus percentage, which is calculatedopportunity (established as a percentage of base salary. For fiscal 2015, the target bonus percentages and actual paid bonuses as a percentage ofeach executive officer’s base salary, forreferred to as the “Target Bonus”).

For each executive officer, 85% of our named executive officers were as follows (excluding Mr. Granger, who retired in January 2015):

If the available pool is not sufficient to allocate each participant acash bonus equal to his or her target bonus percentage multiplied by his or her base salary for the quarter (“full payout”), then the available pool is allocated among each participant in the plan based on the ratio of that participant’s full payout to the aggregate of full payouts for all participants. If the available pool exceeds the amount necessary to allocate each participant his or her full payout, then the excess is allocated among participants in the same manner as shortfalls. The maximum allowable bonus for any quarter is two times a participant’s full payout amount.

The Compensation Committee believes that operating income is the most appropriate metric upon which to base cash incentive bonuses due to the fact that it is highly correlated with both revenue growth and profitability, as well as being the measure of operating results for which our executives can be held most accountable, and thus is the most effective measure of their overall performance. The Compensation Committee also believes operating income to be an appropriate metric based on its historical correlation with our public share price.

The Compensation Committee reviewsopportunity under the Management Bonus Plan achievement levels annually, considering projectedwas evaluated based on multiples (ranging from 0 to 2) 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, 65% of which was based on quarterly financial and operating resultsperformance and paid out quarterly, and 35% of which was based on annual corporate goals and objectives and paid out annually. In addition, for each executive officer, an additional 15% of their cash bonus opportunity under the Management Bonus Plan was evaluated based on a multiple (ranging from 0 to 1) of the Target Bonus related to their individual performance against annual individual goals and objectives as approved by the Compensation and People Committee and paid out annually. Under this Management Bonus Plan, bonuses based on corporate goals and objectives were limited to no more than twice the amount of 85% of the applicable executive officer’s Target Bonus, and bonuses based on individual goals and objectives were limited to no more than 15% of the applicable executive officer’s Target Bonus. 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 annual operating plan or other benchmarks, and other factors discussed below.

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 percentagesBonus opportunities under the Management Bonus Plan are reviewed and approved on an annual basis for each named executive officer and established based on each named executive officer’s role and level of responsibility within the organization. As discussed earlier, the Compensation and People Committee maintained the same target incentive bonus opportunities for all NEOs, except for the CEO which increased to 110% of base salary (from 100% of base salary) to better position the CEO’s target cash compensation with the competitive market. For fiscal 2015, the Compensation Committee determined2021, the target bonus of our new chief executive officer based on negotiation with Mr. Scholhamer. In addition, in March 2015, in connection with his promotion to president and chief executive officer, the Compensation Committee determined to increase Mr. Eichler’s target bonus to 75% of his base salary, from 70% for fiscal 2014. The Compensation Committee determined that these levels were appropriate due to the significance of these executives’ roles in our overall management for fiscal 2015, their status as our most senior executives and the Compensation Committee’s determination of the correlation of their responsibilities with our overall corporate operating performance. Moreover, the Compensation Committee noted that Mr. Scholhamer’s target bonus was consistent with our prior chief executive officer’s target for fiscal 2014 and fiscal 2013. The Compensation Committee set the bonus target percentages for the remaining named executive officers at levels consistent with the prior year.

Target bonus percentages are used primarily to allocate the available bonus pool under our Management Bonus Plan among the plan participants each quarter, and do not necessarily reflect the actual amount of bonuses as a percentage of base salary we are targetingwas increased for our Chief Executive Officer and were otherwise consistent for each of our named executive officers.

The Management Bonus Plan for 2021 included quarterly 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.
(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 2021 as set forth in the Base Salary table above.
Quarterly achievement of corporate goals and objectives for our NEOs for 2021 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 levelsinternal 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 performance.plan for 2021, which plan gets 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 2021 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) growth, measured by the Company’s semiconductor revenue growth as compared to the overall market for wafer fab equipment growth and Services division revenue growth from integrated device manufacturers as compared to the overall market for wafer start growth, (ii) the achievement of key strategic programs for the Company in 2021, including the Company’s ERP implementation, expense reduction, site optimization and product transition goals and (iii) the achievement of key human capital strategic goals, including global alignment of employee benefits, information systems, compensation policies and development plans. Each of these goals was considered challenging but achievable at the time they were established.
Annual achievement of individual goals and objectives for our NEOS for 2021 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 2021 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 quarter of fiscal 2021, the Compensation and People Committee reviewed actual corporate performance against the quarterly corporate scorecards, and in February 2022, the Compensation and People Committee reviewed actual corporate performance for fiscal 2021 against the annual corporate scorecards. The Compensation and People Committee approved payouts under the Management Bonus Plan for each quarter in fiscal 2021 and for the annual 2021 period consistent with the Company’s scorecard achievement.
In February 2022, 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 13.5% (out of 15%) of his Target Bonus based on his achievement of goals. The Compensation and People Committee determined to award our Chief Financial Officer an additional annual individual bonus equal to 15% (out of 15%) of her Target Bonus based on her achievement of goals. The Compensation and People Committee also determined to award our other NEOs additional annual individual bonuses ranging from 13.5% to 15.0% (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 ourthe 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 recognizedrecognizes 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. To help achieve our goal of retaining key talent, an executive must remain an employee through the time the bonus is paid in order to be eligible for any bonus

Consistent with our pay-for-performance philosophy, bonuses for fiscal 2015 were paid out in accordance with the performance goals described above, without adjustment. Actual bonuses for our incumbent named executive officers as a percentage of base salary for 2015 were lower than for 2014 primarily due to our operating results in fiscal 2015 as compared to fiscal 2014.

employee morale.

Equity Compensation

Our equity compensation program is intended to align the interests of our executive officers with those of our stockholders by creating ana 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 2015,2021, consistent with recent years, we granted our named executive officersNEOs a combination of time-based and performance-based restricted stock units, or RSUs whichand PSUs, however, as further described below, in 2021, we believe are effectiveshifted from 1-year to 3-year performance cycles for PSUs. As a result of this transition from a one-year to a three-year PSU program in retaining2021, the Compensation and motivating employees because they providePeople Committee awarded one-time Stub RSUs to help bridge the gap in vesting created by extending the full performance period to three years. As a predictable, tangible value to employees while also serving as an incentive to increaseresult, the valuemix of our stock. RSUs are also an efficient way for us to reduce the dilutive effectsand PSUs is different than prior years.
Mix of equity awards. We grant bothPerformance versus Time-based “Refresh” Grants. The mix of time-based and performance-based RSUsawards for grants made in April 2021 were generally consistent with 2020. 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 executiveChief Executive Officer and 50% to our Chief Financial Officer and Chief Operating Officer would consist of performance-based awards because their roles focus more on overall corporate performance than our other NEOs. For our other NEOs, consistent with prior years, the Compensation and People Committee determined that 25% of the equity awards would consist of performance-based awards.
Performance-Based Equity Design. Throughout late 2020 and early 2021, the Compensation and People Committee worked with Semler Brossy to revise the design of annual PSU awards. The new design was used for fiscal 2021 and granted to NEOs in April 2021. The program represents a shift from a single-metric system with a one-year performance period to a system that considers 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 Ultra Clean 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 Compensation Committee believes this combination provides a balance between awards that provide high incentive value (in the form of performance-based RSUs, which will only vest if we meet performance criteria combined with service requirements) and awards that provide high retention value (in the form of time-based RSUs, which will have at least some value over time while imposing continued service requirements, and requiring time-based vesting of the earnedthree metrics allows for a holistic review of overall company performance units). In fiscal 2015,and focuses on overall top-line revenue growth while ensuring appropriate attention to operating margins and the overall shareholder experience.
For the relative revenue growth and relative TSR performance metrics, the Compensation and People Committee identified a separate group of performance peers that includes a wider range of companies, including non-US companies, exposed to similar dynamics within the semiconductor industry and also identified by several shareholders

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 30, 2021, and the average closing price was $51.55.
One-Time Transition Grants. For our NEOs, the shift from a one-year performance period with an overall three-year ratable vesting schedule to a three-year performance period that cliff vests 100% after three years created a lag between when the historical PSU awards would have vested, had they continued to be granted, compared to when the cliff-vesting awards begin to vest (see illustration below). To cover this gap in vesting, the Compensation and People Committee made a one-time transition grant to our NEOs made up of time-based RSUs that vest 50% after one year and 50% after two years, in each case subject to continued employment through the applicable vesting date. The Compensation and People Committee determined the size of the transition grants by estimating the potential gap in vesting that otherwise would have occurred from the hypothetical future one-year PSU awards while also considering the risk-factor that these potential future PSU awards could go unearned based on performance. These awards are one-time in nature to support the transition to a three-year program and will not be part of the annual program going forward.

Size of FY2021 “Refresh” and Transition Grants.The number of equity awards the Compensation and People Committee granted to each executive officer in fiscal 20152021 was determined based on a variety of factors. In deciding the awards for fiscal 2015, the Compensation Committee consideredfactors, including each individual executive’s job performance but primarilyand his or her level of job responsibility. The Compensation and People Committee also

considered that the Compensation Committee discussed the use of long-term equity awards as a means to retain and incentivize executives as well as our long-term, overall compensation targets. Awards are alsoexecutives. The size of each equity award granted to a NEO in 2021 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 are granted, as well as new hirings and promotions.

were granted.

The number (and related vesting terms) of RSUs granted to our new chief executive officer, Mr. Scholhamer, for fiscal 2015 was determined based on negotiation with Mr. Scholhamer. For Mr. Eichler, the Compensation Committee determined to grant Mr. Eichler an additional 40,000 time-based RSUs in connection with his promotion to our president and chief financial officer in March 2015. Including this promotional grant, the grant date fairtarget value of the RSUslong-term equity granted to Mr. EichlerScholhamer in fiscal 20152021 was set at a target annual equity grant value of approximately $2.5 million along with a transition grant of $1.1 million. The $2.5 million annual grant represented a 25% increase for Mr. Scholhamer compared to his $2.0 million fiscal 2020 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 grant date fair value of the RSUs grantedmidrange provided to Mr. Eichler in fiscal 2014, primarily as a resultcomparable officers by members of our lower stock price, offset by an increasepeer group in determining grants for our non-CEO NEOs for fiscal 2021 (and in the numbercase of RSUs granted.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.

Company.

The equity awards granted during fiscal 20152021 to our named executive officersNEOs are set forth in detail under “Grants of Plan-Based Awards” below. All time-based RSUs granted to our named executive officers (except to our chief executive officer) in fiscal 2015, and all performance-based RSUs earned based on fiscal 2015 performance, vest over a period of 3 years from the grant date in equal annual installments. The RSUs granted to Mr. Scholhamer when he was appointed to become our chief executive officer will vest over a period of 4 years from the grant date in equal annual installments.

Promotional

Promotion and New Hire Grants.

The Compensation and People Committee’s policy has been to make promotionalpromotion grants including Mr. Eichler’s promotional grant in fiscal 2015, on solely a time-based vesting schedule to enhance retention. For Mr. Scholhamer, the Compensation Committee believed it was appropriate and necessary to make his new hire grant on solely a time-based vesting schedule in order to incentivize him to join the Company and because he did not participate in the Company’s business planning for fiscal 2015 prior to his date of hire.

Annual “Refresh” Grants.

The mix of time-based and performance-based awards for annual “refresh” grants made in fiscal 2015 was also consistent with prior years. In allocating equity awards between time-based and performance-based awards, the Compensation Committee considers each named executive officer’s level of responsibility, and the relationship between that named executive officer’s performance and our public share price. Consistent with prior years, the Compensation Committee determined that 50% of the annual “refresh” equity awards that were granted to our president and chief financial officer would consist of performance-based awards because his role focuses more on overall corporate performance than our other incumbent named executive officers. For our other incumbent named executive officers, the Compensation Committee determined that 25% of the equity awards would consist of performance-based awards. Performance-based awards granted in fiscal 2015 to our named executive officers are earned according to the following performance criteria. For fiscal 2015, for purposes of our performance-based awards, operating income is calculated consistent with our Management Bonus Plan.

The Compensation Committee determined, based our actual results for fiscal 2015, that 60% of the performance-based awards granted to our named executive officers in fiscal 2015 were earned. The remaining 40% of such performance-based awards for each applicable executive officer were cancelled.

Grant Practices.Practices. We have implemented procedures to regularize our equity award grant process, such asby 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. Similarly, the Compensation Committee has not timed, nor does it intend in the future to time, the release of material nonpublic information based on equity award grant dates.announcements. 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.

Other Benefit Plans

Deferred Compensation.Compensation. We maintain a non-qualified deferred compensation plan, which allows eligible employees, including executive officers and directors, to voluntarily defer receipt of thea portion of his/her salary above a specified amount 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.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. Our chief executive officer and employees in sales and marketing also received a car allowance.

Because Mr. Lev relocated to Singapore to serve as our senior vice president of Asia, we agreed to provide Mr. Lev with a housing and car allowance. In addition, we agreed to make Mr. Lev whole for any income taxes for which he is responsible above that which he would be responsible for if he received a comparable salary as a resident the United States. No such tax equalization payments were made to Mr. Lev for fiscal 2015. See “—Summary Compensation Table” below for more information.

Other Benefits. 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.

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 a 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.

TABLE OF CONTENTS

Accounting and Tax Considerations

In designing itsour executive compensation programs, the Compensation and People Committee generally considers the accounting and tax effects as well as direct costs. For example, we intend to limit the accounting expense for our equity compensation programs in an amount determined by the Compensation Committee from time to time. When determining how to apportion between differing elements of compensation, the goal is to meet our compensation objectives while maintaining cost neutrality. For example, if we increase benefits under one program resulting in higher compensation expense, we may seek to decrease costs under another program based on our determination of the affordability level. We recognize a charge to earnings for accounting purposes when equity awards are granted. The Compensation and People Committee considers the impact to dilution and overhang when making decisions pertaining to equity instruments.

We do not require executive compensation to be tax deductible for the Company, but instead balance the cost and benefits of tax deductibility to comply with our executive compensation goals.

This includes consideration of Section 162(m) of the Internal Revenue Code, which generally limits our ability to deduct compensation paid to each “covered employee” (as defined in the Internal Revenue Code) to the extent such individual’s compensation exceeds $1 million in any one year.

Compensation and People Committee Report

The Compensation and People Committee of the Board of Directors of Ultra Clean Holdings, Inc. has reviewed and discussed the Compensation Discussion and Analysis, which appears in this proxy statement, with the management of Ultra Clean Holdings, Inc. Based on this review and discussion, the Compensation and People Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in Ultra Clean Holdings, Inc.’s proxy statement.

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.

The following table shows certain information for the

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.
42

TABLE OF CONTENTS

During fiscal 2021, the principal executive officer of Ultra Clean was our Chief Executive Officer, James P. Scholhamer. For fiscal 2021, the combined annual total compensation for Mr. Scholhamer was $5,201,767, and for our median employee was $39,341, resulting in an estimated pay ratio of approximately 132:1.
In accordance with the flexibility provided by Item 402(u) of Regulation S-K, we identified the median employee by aggregating for each applicable employee (A) annual base salary or wage rates for our salaried and hourly employees (including overtime) as of December 31, 2021 (the median employee determination date), (B) the target bonus for 2021 and (C) commission or profit sharing value received. We then ranked this compensation measure for our employees from lowest to highest. This calculation was performed for individuals, excluding our current Chief Executive Officer, James P. Scholhamer, 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 2021 using the same methodology as that utilized for determining the annual total compensation of our NEOs in 2021 (as set forth in the case of Mr. Lev, if we are unable to identify a Replacement Position)2021 Summary Compensation Table on December 25, 2015:

In connection with his retirement, we and Mr. Granger entered into a Transition Agreement, pursuant to which, subject to a release of claims, Mr. Granger received a lump sum cash payment equal to $2,400,000. Mr. Granger also continued to receive his then-current salary and benefits through January 19, 2015. Mr. Granger remains as our non-executive Chairman of the Board of Directors.
