PROPOSAL 1

ELECTION OF DIRECTORS

Nominees

The Company’s Amended and Restated Certificate of Incorporation (“Charter”) provides that directors shall be elected at each Annual Meeting of Stockholders, and that each director of the Company shall serve until the expiration of the term for which he or she is elected and until his or her successor is duly elected and qualified, or until his or her earlier death, resignation, disqualification or removal.

Based on the recommendation of the Nominating & Governance Committee, the eight director nominees approved by the Board for inclusion in this proxy statement and for election at the Annual Meeting are:

Each nominee is currently serving as a director of Onto Innovation. In making its recommendations, the Nominating & Governance Committee considered a number of factors, including its criteria for Board membership, which include the qualifications that must be possessed by a director candidate in order to be nominated for a position on our Board. Each nominee has indicated that he or she will serve if elected. Unless otherwise instructed, the proxy holders will vote the proxies received by them for the Company’s eight nominees. In the event that any nominee of the Company becomes unable or unavailable to serve as a director at the time of the Annual Meeting (which we do not anticipate) the proxy holders will vote the proxies for any substitute nominee who is designated by the current Board to fill the vacancy. Alternatively, the Board, in its discretion, may elect not to nominate a substitute and to reduce the size of the Board. We do not have any reason to believe that any of the nominees will be unable or will decline to serve as a director.

Board Composition and Refreshment

A priority of the Nominating & Governance Committee and the Board as a whole is making certain that the composition of the Board reflects the desired professional experience, skills, and backgrounds in order to present an array of viewpoints and perspectives, help develop and execute strategy for the future, and effectively represent the long-term interests of stockholders. Further, the Board recognizes the importance of Board refreshment in order to continue to achieve an appropriate balance of tenure, turnover, diversity, and skills on the Board.

Vote Required

Pursuant to the Company’s Amended and Restated Bylaws (“Bylaws”), our directors are elected by the affirmative vote of the majority of the votes cast (provided, however, that if the number of nominees exceeds the number of directors to be elected, directors will be elected by a plurality voting standard). In order for a director in an uncontested election to be elected, the number of votes cast “for” his/her election must exceed the number of votes cast “against” his/her election (with “abstentions” and “broker non-votes” not counted as a vote cast either “for” or “against” that director’s election). If a nominee who is an incumbent director receives a greater number of “against” votes for election than “for” votes in an uncontested election and is not elected, our Corporate Governance Guidelines provide that such director must promptly tender a resignation to the Board. Our Nominating & Governance Committee would then make a recommendation to the Board on whether to accept or reject the tendered resignation, or whether other action should be taken. Within 90 days after the date of the certification of the election results, our Board will act on any such tendered resignation and publicly disclose (in a press release, a filing with the SEC, or other broadly disseminated means of communication) its decision regarding the tendered resignation and the rationale behind the decision.

Information about the Nominees and Continuing Directors

Our Board and its Nominating & Governance Committee believe that all of the director nominees are highly qualified, have demonstrated leadership skills, and have the requisite experience and judgment in areas that are relevant to our business. We believe that their ability to challenge and stimulate management and their dedication to the affairs of the Company collectively serve the interests of the Company and its stockholders. The Company is unaware of any arrangements or understandings between any director or nominee and any other person(s) pursuant to which any director or nominee was or is to be selected.

The eight nominees for director are set forth below. All information is as of the record date.

There are no family relationships between any directors or executive officers of the information that you should consider,Company.

Corporate Social Responsibility

An important part of advancing the semiconductor industry through our innovation is being a socially responsible company. Our Company’s core values of Passion, Integrity, Collaboration, and Results underpin our commitments to sustainable growth and to making a positive contribution to people and the planet. We strive to achieve responsible and sustainable business practices and continuous improvement in our own operations, in our partnerships with our customers, across our supply chain, and in our engagements with our other stakeholders. Our Company invests in environmental, social, and governance (“ESG”) initiatives across our business and integrates ESG principles into our day-to-day operations.

Business and Governance. Our Company has established a cross-functional ESG executive leadership team that is responsible for proposing goals, developing and executing strategy, and embedding ESG into our operations management. This ESG leadership team provides regular updates to the Board and engages them to discuss ESG strategy, gain alignment on goals, and report on progress. Our Board is actively engaged in the Company’s ESG oversight and has the primary responsibility for our ESG priorities. Board committees provide further guidance and oversight on relevant ESG topics including the Compensation Committee on human capital management, the Audit Committee on information security and the Nominating & Governance Committee on ethics compliance.

Workplace. As described in the “Social Programs” section in our 2022 ESG Report, our Company strives to provide a work environment that fosters inclusion and diversity, ensures every voice is heard, and enables employees to achieve their full potential. Our Company aims to maintain a collaborative, supportive, and opportunity-rich culture that enhances innovation and employee engagement. We strive to protect the health and safety of our personnel throughout our entire operation, including our offices, manufacturing sites, research and development (“R&D”) centers, and our field team working at customer sites.

Community. Our Company believes that positively involving our employees and giving back to our community is central to our culture and an expression of our core values. In 2021, the Company initiated RISE (Reimagining Initiatives for Society and the Environment) Teams, which have direct oversight from the ESG leadership team. These teams are formed at each location globally in order to promote environmental sustainability, community engagements, local charitable giving including employee volunteer hours and employee donations. Our RISE Teams’ philanthropy and volunteerism programs provide financial and human services to improve the quality of life in the communities in which we operate. We are committed to creating positive impacts in communities around the world by contributing to local, national, and international organizations that support community needs such as hunger, food and water security, disadvantaged children and senior citizens, health improvement, and environmental protection.

Sustainable Operations. We believe that incorporating environmental sustainability into business leads to better products, more efficient operations, and added value for our customers. As the world tackles climate change and other critical environmental issues, we seek to do our part by responsibly managing our impact with global goals for renewable energy use, carbon footprint per person, water conservation, beneficial use, and landfill hazardous waste reduction and elimination. We carefully monitor and manage our environmental impact across our business and work to implement cost-effective best practices, focusing our efforts where we believe we can have the biggest long-term impact. Our Company looks at impacts from procurement to manufacturing, during R&D and product design, and throughout a product’s lifecycle. We carefully manage our environmental impact, set goals, and report progress annually through our annual ESG report, which is carefully reviewed and verified by our internal audit function.

Products and Customers. Our Company demands excellence in our quality and environmental performance, as demonstrated through our product and process qualification commitments, which resulted in our ISO 9001 Quality Management certification. We continuously strive to develop innovative products and solutions that help our customers improve their product yields and reduce the amount of scrapped materials. We seek to achieve this through our monitoring processes and by alerting customers via our software products before specification limits are reached, thereby helping customers avoid product test failures. In addition, our equipment meets or exceeds safety requirements and incorporates higher throughput to reduce the energy required to process customer products on a per unit basis, benefiting our customers and the environment. Our Company also strives to extend the life of our products and solutions to enable our customers to realize greater value from our products with a potentially lower environmental impact.

Responsible Supply Chain. Our Company understands the importance of an ethical, responsible, resilient, and diverse supply chain, and we engage with our suppliers to address a wide range of issues including human rights, humane treatment, freely chosen employment, labor, anti-corruption, supplier diversity, environmental impact, and responsible mineral sourcing. We are a strong proponent of supply-chain-related industry standards and endeavor to uphold the guidelines published by the Responsible Business Alliance (“RBA”). Since joining in 2021, the Company has been an affiliate member of the RBA, the world’s largest industry coalition dedicated to corporate responsibility in global supply chains. Beginning in 2022, our direct suppliers are expected to adhere to our Global Supplier Code of Conduct, which incorporates the RBA code of conduct and covers topics such as ethics, integrity, transparency, anti-corruption, conflict minerals, human trafficking, environmental sustainability, and social responsibility. Acknowledgment of and consent to adhere to our Global Supplier Code of Conduct is a mandatory requirement of our new supplier onboarding process.

COMPENSATION DISCUSSION AND ANALYSIS

Introduction

This Compensation Discussion and Analysis (“CD&A”) describes our compensation philosophy, process, plans, and practices for our executive officers and contains a discussion of the material elements of compensation awarded to, earned by, or paid to the Company’s named executive officers or “NEOs.” The Company’s NEOs for 2023 were:

2023 Compensation Highlights

Executive compensation is a key component of our corporate governance practices and our plans to drive long-term profitable growth. We’ve designed our compensation program to both attract and retain best-in-class executive management and to motivate our executive officers to achieve corporate objectives and create value for stockholders. In 2023, key features of our compensation program included the following:

Results Of The 2023 Stockholder Vote On Executive Officer Compensation

In 2023, stockholders were provided with the opportunity to cast an advisory (non-binding) vote (a “say-on-pay” proposal) on the compensation of our NEOs for fiscal 2022. Our stockholders approved this say-on-pay proposal, with 96.2% of votes cast voting in favor of our executive compensation program. Our Compensation Committee and Board recognize the fundamental interest our stockholders have in the compensation of our executive officers. Noting the strong support for our 2022 compensation program, the Compensation Committee maintained a consistent approach to our executive officer compensation program in 2023.

The Compensation Committee will continue to consider input from our stockholders as reflected in the outcome of our annual say-on-pay vote when making executive compensation program decisions.

COMPENSATION PROGRAM OBJECTIVES, DESIGN, AND PRACTICES

Our Compensation Philosophy And Principles

Our compensation philosophy, which serves as the framework for the Company’s executive officer compensation program, is defined by two key tenets: (1) rewarding continuous improvement in financial and operating results and (2) creation of stockholder value. The Compensation Committee acts on behalf of the Board and, by extension, on behalf of our stockholders, to establish, implement, and continually monitor adherence to our compensation philosophy. Accordingly, the Compensation Committee has developed a set of core objectives and principles that it has used to develop the executive officer compensation program. The specific objectives of our executive officer compensation program are to:

Consistent with the foregoing, the Compensation Committee believes that the most effective executive officer compensation program is one that rewards the achievement of specific strategic and operating goals of the Company on both an annual and a long-term basis, and that incentivizes executive officers to create value for stockholders. The Compensation Committee evaluates both performance and compensation to ensure that the Company maintains its ability to attract and retain superior employees in key positions. Based on that evaluation, the Compensation Committee designs the compensation provided to executive officers to remain competitive with the compensation paid to similarly situated executive officers at peer group companies. The Compensation Committee believes executive officer compensation packages provided by the Company to its executive officers, including the NEOs, should include base salary, annual cash incentive opportunities, and long-term stock-based compensation, including equity incentive opportunities that reward performance as measured against pre-established goals.

The following principles support the objectives and design of the compensation program:

To underscore the importance of “pay-for-performance” in our compensation philosophy, the Compensation Committee has developed incentive arrangements based on performance standards that the Compensation Committee believes, at target achievement, will incentivize our executive officers to meet or exceed industry performance.

The Company also strives to promote an ownership mentality among its key leadership, in part through the guidelines described below under the heading “Stock Ownership/Retention Guidelines.” To that end, the CEO is required to maintain ownership of Common Stock equal in value to at least three times the CEO’s year-end base salary. The other executive officers are required to maintain a minimum share ownership level equal in value to their current year-end base salary. In further support of this approach, the Company prohibits pledges of Company securities as collateral, as well as short sales, derivative and hedging transactions involving Company securities, to ensure that personal interests relating to the stock holdings of officers and directors do not conflict with their duties to the Company.

Our Compensation Practices

The Compensation Committee has adopted the following practices and policies with respect to the Company’s executive officer compensation program:

COMPENSATION DECISION-MAKING PROCESS

Determination of Compensation Awards

The Compensation Committee’s goal is to target elements of compensation within a competitive range, using a balanced approach that does not use rigid percentiles to target pay levels for each compensation element. For 2023, the Compensation Committee reviewed each element of compensation described below and set the target total direct compensation opportunities of our executive officers after taking into consideration the following factors:

The Compensation Committee does not assign relative weights or rankings to any of these factors and does not solely use any quantitative formula, target percentile or multiple for establishing compensation among the executive officers or in relation to the competitive market data.

Role of the Compensation Committee

The Compensation Committee is charged with making all final determinations regarding the compensation of our executive officers. In the beginning of each year, the Compensation Committee evaluates the CEO’s performance in light of the goals and objectives established at the beginning of the previous fiscal year for measuring his performance. The CEO does not participate in the Compensation Committee’s or Board’s deliberations regarding his compensation. The CEO meets with the Compensation Committee to present the proposed compensation plans for each of the Company’s executive officers other than the CEO, including the other NEOs. Based on these meetings and internal deliberations, the Compensation Committee then approves the annual compensation for the Company’s CEO and other executive officers, including the NEOs, including base salary, cash incentive award opportunity, and equity compensation.

In the same time period, the Compensation Committee also reviews and recommends for approval by the Board:

In reviewing and setting the annual compensation for each executive officer, the Compensation Committee considers the amounts payable under each of the elements of their respective compensation plans, including base salary, annual cash incentive awards, and equity grants. The Compensation Committee takes into consideration both the Company’s internal pay equity as well as the competitive environment within which the Company operates. The Compensation Committee then determines whether the base salary and annual and long-term incentive award opportunities for the individual executive officers support the Company's compensation objectives and are both competitive and reasonable in the context of the Company’s competitive market.

Role of Management

With regard to compensation for executive officers other than the CEO, the Compensation Committee seeks input from the CEO and the human resources department. Each year, the CEO is responsible for establishing proposed personal and corporate objectives for the Company’s other executive officers, including the other NEOs. These objectives, subject to the approval of the Compensation Committee, are reviewed and agreed upon by the CEO with the applicable executive officer. In addition, as part of the annual performance review of the Company’s executive officers, the CEO assesses the performance of his direct reports and recommends any merit increase to be proposed for each individual. These recommendations are compiled by the CEO into executive officer compensation plans which include any proposed merit increases, each executive officer’s personal and corporate objectives, proposed annual incentive award opportunities (expressed as a percentage of their base salary) and equity grant proposals, and are submitted to the Compensation Committee for review and consideration for approval. At the Compensation Committee meeting during which the executive officer compensation plans are reviewed, the CEO attends the initial session to present the proposed plans and to answer questions. Thereafter, the Compensation Committee meets without the CEO present to review, discuss and approve all executive officer compensation plans, subject to any modifications made by the Compensation Committee.

Role Of The Compensation Consultant

The Compensation Committee may retain independent compensation consultants to assist the Compensation Committee in discharging its duties. During 2023, the Compensation Committee engaged Compensia, an independent executive officer compensation consulting firm, to provide advice on the Company’s executive officer compensation arrangements. Compensia does not provide any services other than those related to compensation consulting and does not provide any services to the Company's management. The Compensation Committee determined that Compensia is independent within the meaning of the NYSE Listing Rules, and that the work performed by Compensia does not raise any conflicts of interest.

For 2023, the Compensation Committee requested that Compensia:

Peer Companies

In setting executive officer compensation, the Compensation Committee evaluates compensation levels for executive officers at other similarly situated companies. For 2023, the Compensation Committee engaged Compensia to provide peer group data and perform an assessment of compensation levels provided to executive officers. In addition, the Compensation Committee obtains and evaluates market compensation information using third-party and internal resources. The Compensation Committee reviews data related to compensation levels and programs of other similar companies prior to making its decisions, but only considers such information in a general manner in order to obtain a better understanding of the current compensation practices within our industry.

In the Compensation Committee’s review of executive officer compensation for the 2023 fiscal year, the Compensation Committee considered publicly available market data from peer company proxy disclosures and industry compensation surveys for companies that typically include similarly sized semiconductor and semiconductor capital equipment companies or similar firms for each Company executive officer in a like or similar role.

In mid-August of 2022, for compensation decisions for the Company’s 2023 fiscal year, Compensia recommended and the Compensation Committee approved the Company’s compensation peer group which took into consideration the following factors:

The Company’s compensation peer group used to make decisions regarding 2023 compensation consisted of the following companies:

The pay practices of the foregoing Company peer group were analyzed for base salary and annual and long-term incentives. Periodically, peer groups are used to evaluate other programs such as executive officer retirement, perquisites and severance policies. Our peer group data is supplemented by broader technology industry data from compensation surveys to further facilitate the evaluation of compensation levels and design. Compensation levels are generally developed at the low (25th percentile), middle (50th percentile) and high (75th percentile) end of the market for each pay element (base salary and short-term and long-term incentives) and for total compensation.

While the Compensation Committee considers market data for each pay element and in total, the Compensation Committee does not specifically target any particular market compensation level. Instead, the Compensation Committee uses its discretion in setting the compensation levels as appropriate.

ELEMENTS OF THE COMPANY’S 2023 COMPENSATION PLAN

Compensation Program Design

Our executive officer compensation program, which applies to all executive officers including our NEOs, is composed of three parts, each of which is intended to address different locationobjectives: base salary, annual cash performance incentives, and long-term equity incentives.

Base salaries serve as the foundation of our executive compensation program. The Compensation Committee uses base salary and certain other benefits available to all employees, such as the Onto Innovation Inc. 2020 Employee Stock Purchase Plan (“ESPP”), our 401(k) plan with Company matching contributions, and health and welfare benefits, as a means for providing base compensation to executive officers commensurate with their knowledge and experience and for fulfilling their basic job responsibilities. The Compensation Committee also derives the other executive compensation elements, annual cash incentives and long-term equity incentives, by weighing them against base salary. As discussed above, the Compensation Committee generally establishes base salary levels for executive officers at or solelynear the start of each year.

The annual cash incentive component of the Company’s executive officer compensation program rewards executive officers for achieving specific corporate, business unit (as applicable) and individual goals. The Company’s annual cash incentive awards are administered through its Management By Objectives (“MBO”) bonus plan. The MBO bonus plan provides guidelines for the calculation of annual cash incentive compensation, subject to the Compensation Committee’s oversight. At its first meeting each year, the Compensation Committee typically determines final bonuses for executive officers earned in the preceding year based on each individual’s performance, the performance of the Company through its audited financial statements, business unit performance (as applicable), and the CEO’s recommendations (except with respect to the CEO's own bonus).

The long-term equity incentive component includes grants of (i) performance-based stock units (“PSUs”), which are earned based on the Company's total shareholder return (“TSR”) relative to the top 30 companies in the Philadelphia Stock Exchange Semiconductor Index (SOX) over two- and three-year performance periods, and (ii) time-based RSUs, which vest in equal annual increments over time. All grants are made under the Company’s 2020 Stock Plan and shares earned and vested are subject to the Company’s stock ownership and retention guidelines and insider trading policy. The Compensation Committee generally approves the grant of annual equity awards to officers at its first regularly scheduled meeting each year. The Compensation Committee does not generally grant equity awards at other times during the year, other than in the case of a new hire, promotion or other exceptional circumstances.

The Compensation Committee aligns both the Company’s annual cash incentive plan and long-term equity incentive program with the Company’s performance relative to pre-established performance goals based on the Company’s stated financial objectives, historical performance, and anticipated market and economic conditions for the performance period. The Compensation Committee seeks to structure the equity and cash incentive compensation program to motivate executive officers to achieve the business goals set by meansthe Company and reward the executive officers for achieving such goals, which we believe aligns the financial incentives of remote communication (i.e.our executive officers with the interests of our stockholders.

The table below summarizes the foregoing key elements of our executive officer compensation structure for 2023.

In adopting this design, the Compensation Committee considered a number of parameters, including the advice of its independent compensation consultant, comparable practices within the industry, and the desire to achieve the goals underlying the compensation program. The Compensation Committee and Board further believe that each of the elements as well as the entire compensation package for Company executive officers is appropriate given the Company’s performance, industry, current challenges, and environment.

The three components of our executive compensation program are commonly used for executive officers at companies within the Company’s peer group and, therefore, the Compensation Committee found them to be appropriate in its talent attraction and retention strategy. Given that a substantial portion of an executive officer's overall compensation is tied to individual and Company performance through the annual cash incentive and long-term equity incentive components, we also think the structure of our executive compensation program meets the Company's other objectives of motivating executive officers to achieve the Company's short- and long-term business strategies and objectives and aligning the interests of executive officers with those of our stockholders. The pay-for-performance nature of our compensation structure rewards the achievement of strategic, operational and financial goals, thereby enhancing stockholder value.

The Compensation Committee’s compensation determinations vary for each executive officer depending on a number of factors, including but not limited to, the scope of his or her responsibilities, leadership skills and values, and individual performance. The Compensation Committee does not apply formulas or assign specific mathematical weights to any of these factors, but rather exercises its business judgment and discretion to make a subjective determination after considering all of these measures collectively.

Annually, the Compensation Committee reviews the elements of the compensation package as well as the overall package afforded to the executive officers. At such time, the Compensation Committee, in its discretion, can approve adjustments to the elements of the program. This review is typically performed coincident with the evaluation of each executive officer’s performance in relation to his or her cash incentive compensation goals, salary adjustment, and equity grants, if any, as discussed in more detail in the sections below.

Impact Of Performance On Compensation

The performance of the Company and of each executive officer has a direct impact on the compensation received by such executive officer. On an annual basis, the CEO reviews the performance and compensation for the Company’s other executive officers to determine any potential salary adjustment for each individual. The CEO then proposes (except with respect to the CEO’s own compensation) to the Compensation Committee the annual cash incentive payout to executive officers, including the NEOs, under the MBO bonus plan, the target cash incentive compensation for the upcoming year, any base salary adjustments, and equity award amounts for the upcoming year. Each of these recommendations, and the Compensation Committee’s final compensation determination for executive officers, is based on each executive's performance and contributions to the Company, as well as overall Company performance.

The structures of the Company’s annual cash incentive and long-term equity incentive components of the compensation program are also both intended to incentivize performance. The MBO bonus plan includes various incentive level opportunities based on the executive officer’s accountability and impact on Company operations, with target award opportunities that are established as a percentage of base salary.

Under our MBO bonus plan, payout is based upon achievement of corporate, business unit (as applicable), and personal objectives, with no payout unless the Company meets the threshold level of at least one of the Board-approved corporate financial targets established as part of the plan. Personal objectives are awarded only upon clear achievement of the associated goal. Failure to meet the personal objectives thereby has a virtual-only meeting). If we changenegative impact on the meeting location, we will announce any such updatesultimate bonus payout, even when the Company achieves its corporate goals.

The CEO recommends to the Compensation Committee individual performance goals for the executive officers (including the NEOs), other than the CEO, for the current year, which are combined with the corporate and business unit (as applicable) targets into an annual cash incentive opportunity proposal. The personal targets that are established are designed to result in additional incremental value to the Company if they are achieved. The target level of the corporate and business unit components of the bonus goals are set based on the Company’s financial budget established by the Board at the beginning of the year. The determination of these goals is made annually to meet the changing nature of the Company’s business.

Upon completion of the prior year’s results and prior to implementation of the current year’s proposed executive compensation plan, the results for each executive officer are submitted to, and reviewed by, the Compensation Committee, which considers the CEO’s recommendations for executive officers, other than the CEO, and determines the final bonus earned by each executive officer based on Company and individual performance. The Compensation Committee may exercise discretion in adjusting and approving an individual’s award under the bonus plan based upon its review.

The two elements of the Company’s long-term equity incentive compensation program are also performance-based. The PSU grants, which are explained in further detail below, measure the Company’s TSR over two- and three-year periods as compared to that of companies in the Philadelphia Semiconductor Index (SOX) and reward executives for achieving TSR greater than that of other Companies in the Index. In addition, because the value of PSUs and the service-based RSUs granted to executive officers are tied to the Company's stock price, their value increases or decreases with the performance of the Company stock, further incentivizing executives to manage the Company for the benefit of the Company's stockholders.

Based upon the foregoing, the compensation that an executive officer may realize is significantly impacted by the positive or negative performance of such individual as well as Company performance.

Compensation Plan Design And Decisions For 2023

For 2023, the Compensation Committee conducted a review of the compensation program and determined that the 2023 executive compensation plan would retain the same basic elements as the prior year’s plan as these elements aligned the Company’s program with its current business strategy and included the pay for performance aspect of its executive compensation program. Taking into account the Company’s 2022 financial performance and outlook for 2023, each executive officer’s performance and responsibilities, and current market compensation rates for each executive officer position, among other criteria, the Compensation Committee approved the program and compensation plan structure for the executive officers in 2023 as detailed below.

Base Salary

The Company provides executive officers and other employees with a base salary to compensate them for services rendered during the fiscal year. The Compensation Committee supports the compensation philosophy of moderation for elements such as base salary and other executive officer benefits. As noted above under “Impact of Performance on Compensation,” base salary decisions are made as part of the Company’s formal annual review process and are influenced by the performance of the Company and the individual.

For 2023, the Compensation Committee reviewed and determined salaries after reviewing salary data supplied by the independent compensation consultant, including data regarding the peer comparison group, as well as consideration of the compensation for the executive officers on a company-wide basis, based on their relative duties and responsibilities and the recommendations of the CEO (other than with respect to his own compensation). The Compensation Committee did not apply formulas or assign specific mathematical weights to any of these factors, but rather exercised

its business judgment and discretion to make a subjective determination regarding each executive officer's base salary for 2023, as applicable, after considering all of these factors collectively. The CEO’s recommendations for salary adjustments (other than his own) were reviewed, modified, and approved as deemed appropriate by the Compensation Committee.

The table below shows the increases in NEO base salary for 2023 that were approved by the Compensation Committee. Our CEO’s base salary was increased 10% to better align with the practices of our peer group, taking into consideration our strong performance relative to peers and a finding that his prior pre-increase base salary was below the 25th percentile of the peer group market data.

Annual Cash Incentive Compensation

For 2023, as in prior years, the annual cash incentive plan was structured such that each NEO’s potential cash award was subject to the achievement of 2023 corporate financial objectives. These corporate financial objectives were established at levels in excess of the overall industry projections in order to incentivize the Company to outperform the industry.

For our NEOs the 2023 target annual cash bonus opportunities were set as follows:

The 2023 annual cash incentive plan had three components: corporate goals, business unit goals (if applicable), and personal performance goals, each of which is described in more detail below.

The following table reflects the structure of the corporate and business unit goal components of the cash incentive compensation plan. The personal goal payout component is fixed -- if achieved, the payout is for the target amount.

The following table reflects the Corporate targets, actual results, and percentage payouts for fiscal 2023 for the CEO and other executive officers.

In 2023, none of the NEOs included a business unit goal component as part of his or her cash incentive compensation plan. Personal goal achievement for the CEO and other NEOs at the time of the incentive award is shown in the table below.

Actual amounts paid to the CEO and the other NEOs under their respective annual cash incentive plans are reported below in the Non-Equity Incentive Plan Compensation column of the Summary Compensation Table.

Long-Term Equity Incentive Plan

In 2023, the structure of the long-term equity incentives was set by the Compensation Committee through the consideration of a number of factors and recommendations from the CEO (except in connection with his own grants).

The following parameters were included in the design of the long-term equity incentive program in 2023:

Performance-Based Stock Units: 50% of each executive officer’s equity grant was comprised of PSUs. The relative TSR plan design includes the following features:

Service-Vesting Restricted Stock Units: 50% of each executive officer’s equity grant is comprised of service-based RSUs, which vest in equal annual increments over three years.

The following table summarizes the components of the long-term equity incentive program.

In February 2024, the first tranche of the PSUs awarded in 2022 vested. The Company’s TSR performance based on the 20-day average market value prior to the vesting date was determined and ranked against the participating companies in the SOX. The Company’s TSR for this assessment period was 75.4%, which placed the Company at the 93rd TSR percentile in the SOX. Therefore, the PSUs earned as a percent of the target number awarded was 200%.

Also in February 2024, the second tranche of the PSUs awarded in 2021 vested. The Company’s TSR performance based on the 20-day average market value prior to the vesting date was determined and ranked against the participating companies in the SOX. The Company’s TSR for this assessment period was 178.6%, which placed the Company at the 96th TSR percentile in the SOX. Therefore, the PSUs earned as a percent of the target number awarded was 200%.

The actual number of PSUs and RSUs granted to the NEOs in 2023 and the related value are reported below in the table titled Grants Of Plan-Based Awards In 2023.

Personal Benefits And Perquisites

Benefits

All employees of the Company, including its executive officers, are eligible to participate in the following benefit plans and programs:

The Company, in its discretion, may offer to reimburse the expenses that an employee incurs as a result of the Company requiring the individual to relocate their primary residence for employment purposes. TheCompensation Committee believes that these benefits are consistent with industry practice and are important in recruiting and retaining qualified employees.

Limited Perquisites

The Company does not offer extensive perquisites to our executive officers. For 2023, the Compensation Committee reviewed the potential perquisites to be offered by the Company to the executive officers and determined that such perquisites would be limited to Company-paid tax preparation services and Company-paid membership in one airline executive club. Executive officers are also eligible to participate in the Company’s Charitable Match Program, under which the Company will match, dollar for dollar, up to $1,000 in donations to eligible charitable organizations. The Compensation Committee believes that these benefits are reasonable and consistent with the Company’s overall compensation program and enable the Company to attract and retain superior employees for key positions.

Retirement Provision For Equity Awards

All employees, including our NEOs, are also eligible to participate in the Company’s post-retirement equity award vesting program. Under that program:

Employee Stock Purchase Plan

The Company (as successor to Nanometrics) has maintained an Employee Stock Purchase Plan since 1986. The Company’s 2020 Employee Stock Purchase Plan was approved by stockholders in 2020 and is currently administered by the Compensation Committee.

Under the terms of our current Employee Stock Purchase Plan, eligible employees may elect to have up to fifteen percent (15%) of eligible compensation deducted from their base salary and applied to the purchase of shares of Common Stock. The price the employee pays for each share of Common Stock is eighty-five percent (85%) of the fair market value of Common Stock at the end of the applicable six-month purchase period. The Employee Stock Purchase Plan qualifies as a non-compensatory plan under Section 423 of the Internal Revenue Code of 1986, as amended (“IRC”).

CORPORATE AND GOVERNANCE POLICIES

Employment And Change-In-Control Agreements

Each of the NEOs, other than Mr. Slicer, is entitled to payments upon a qualifying termination of employment following a change-in-control event. The Compensation Committee believes that providing severance in a change-in-control situation is beneficial to stockholders so that executive officers may remain objectively neutral when evaluating a transaction that may be beneficial to stockholders yet could negatively impact the continued employment of the executive officer.

The Company is party to an employment agreement with Mr. Plisinski that provides for certain benefits upon termination or a change in control of the Company. We have also entered into an Executive Change in Control Agreement with each of our other current NEOs, other than Mr. Slicer.

See “Potential Payments Upon Termination Of Employment Or Change In Control” below for a description of these arrangements and potential payments that the NEOs would have been entitled to receive upon applicable hypothetical termination scenarios as of December 30, 2023.

Other Elements Of Post-Termination Compensation

The Company does not have a practice of providing retirement benefits, including any supplemental executive officer retirement plans (SERP), to its executive officers, other than through its 401(k) plan and post-retirement vesting for equity awards granted by the Company, as described above. The Company retains the discretion to utilize the offer of severance and/or change-in-control protection as an incentive in its hiring and retention of executive officers.

Non-Solicitation And Non-Competition Policy

The Company maintains a policy of entering into an agreement with each of its new executive officers, which contains both non-solicitation and non-competition provisions. Each of our NEOs is party to such an agreement. The non-solicitation provisions apply for one year (or two years in the case of Mr. Plisinski) after termination of the individual’s employment while the non-competition provisions are in effect during the individual’s employment and generally for one year thereafter, to the extent permitted by applicable law. In all cases, these covenants have been implemented to protect the confidential information, goodwill and other assets of the Company. For those individuals with employment agreements, should a breach of the non-solicitation or non-competition terms of their agreements occur, this could give rise to the Company declaring a breach under the agreement and terminating all severance payments thereunder.

General Termination Benefits

Upon termination of an executive officer’s employment with the Company, the individual is entitled to receive his or her base salary earned through the termination date. Thereafter, further cash compensation to the executive officer is discontinued, except to the extent that severance or change-in-control payments are required to be made in accordance with individual or Company severance protection arrangements. Pursuant to his employment agreement with the Company, Mr. Plisinski is entitled to elect to continue group health or other group benefits as allowed by COBRA with continued Company co-payments for agreed post-termination periods. The Company retains the right to offer severance and/or payment of COBRA benefits to any individual who is terminated from the Company at its discretion. See “Potential Payments Upon Termination Of Employment Or Change In Control” below for a further description of these arrangements.

Stock Ownership Policy

The Company has established a stock ownership policy for its non-employee directors and executive officers subject to Section 16 reporting requirements, which is designed to align the interests of Company leadership with the interests of stockholders and give Company leadership a stake in the long-term financial future of the Company.

The stock ownership levels currently in effect under the policy are the following:

In assessing compliance with the foregoing guidelines, the Company takes into consideration only the ownership of Common Stock in the Company and unexercised stock options that are vested and “in-the-money.” As a result, unearned PSUs, unvested service-based RSUs, and unvested stock options do not qualify as shares for purposes of compliance with the Company’s stock ownership and retention guidelines.

Participants are expected to achieve their ownership guideline target within five years of becoming subject to the policy. Existing participants were subject to this policy as of the date of the policy and any new participants will be subject to the policy on their hire, promotion, election, or appointment date, as applicable.

Compliance with the Company’s stock ownership and retention guidelines is reviewed annually by the Compensation Committee. As of its review in February 2024, the Compensation Committee determined that all executive officers and directors were in material compliance with the ownership requirements. There are no specific penalties for failure to achieve the ownership guideline target. However, the Compensation Committee retains the discretion to impose such other conditions, restrictions, or limitations on any executive officers or directors as such Committee determines to be necessary or appropriate in order to achieve the purposes of the stock ownership policy.

The Compensation Committee regularly reviews the Company’s stock ownership and retention guidelines. In the course of its annual review for 2025, the Committee will evaluate the appropriateness of the foregoing stock ownership levels based in part on the average closing price of a share of the Company’s stock during the 30 consecutive trading days ending on and including the last day of the most recently completed fiscal year, as well as other considerations such as market conditions and comparable practices within the industry.

Prohibition On Pledging, Margining or Hedging Of Company Stock

Our insider trading policy prohibits Company directors and employees, including our executive officers, from purchasing Company securities on margin, borrowing against Company securities held in a margin account, or pledging Company securities as collateral for a loan. Company directors and employees are also prohibited from engaging in short sales, derivative transactions, and hedging transactions involving Company securities.

Adjustments Or Recovery Of Prior Compensation

In August 2023, the Company adopted a policy that requires it to recover from its Covered Executives (which includes our NEOs) certain excess incentive compensation that would not have been earned based on specified accounting restatements (the “Clawback Policy”). The Clawback Policy covers any compensation that is granted, earned, or vested based wholly or in part upon the attainment of certain financial reporting measures and received by a Covered Executive during the last three completed fiscal years immediately preceding the relevant accounting restatement date. The Clawback Policy is consistent with the requirements of the SEC’s final compensation clawback rules under the Dodd-Frank Act and NYSE listing standards.

Compensation Program Risk Assessment

In 2023, the Compensation Committee, with advice and input from Compensia, its independent compensation consultant, reviewed our compensation program and whether compensation design features may have the potential to incentivize executive officers to take risks that are reasonably likely to have a material adverse effect on the Company. Among others, the Committee reviewed the following features of our compensation program: compensation philosophy and pay mix; performance measures used in incentive plans; goal setting and payout leverage and caps; calculation and verification of performance outcomes for incentive payments; and mitigating factors built into the program to reduce risk. Based on this review and the input from Compensia, the Compensation Committee concluded that the Company’s compensation program does not create risks that are reasonably likely to have a material adverse effect on the Company.

IRS Limits On Deductibility Of Compensation

Prior to the enactment of the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) in December 2017, Section 162(m) of the IRC, limited the tax deductibility of annual compensation in excess of $1 million paid to any public corporation’s CEO and three other highest-paid executive officers (other than the chief financial officer). Certain qualifying performance-based compensation was not subject to the $1 million deduction limit, however. With the passage of the Tax Act, only qualifying performance-based compensation paid pursuant to a binding written contract in effect on November 2, 2017 (and not modified in any material respect on or after November 2, 2017) as set forth under the Tax Act will be eligible for the deduction exception. The Tax Act also expanded the executive officers covered by Section 162(m) to include the chief financial officer as well as any person who ever was a covered executive officer for any prior taxable year, beginning after December 31, 2016. As a result of these changes, starting in 2018, compensation payable by us in excess of $1 million to any person who was an NEO since fiscal year 2016 is non-deductible, regardless of whether the compensation is performance-based.

Although the Compensation Committee considers deductibility issues when approving executive officer compensation elements, the Compensation Committee believes that the other compensation objectives, such as attracting, retaining and providing appropriate incentives to executive officers, are important and can supersede the goal of maintaining deductibility. Consequently, the Compensation Committee generally makes compensation decisions without regard to deductibility, as the Compensation Committee believes it has appropriately structured its compensation programs to provide incentives to our executive officers to increase Company return and stockholder value.

CONCLUSION

In reviewing its compensation programs, the Company has concluded that each element of compensation as well as the total compensation opportunities for its executive officers, including the NEOs, are reasonable, appropriate and in the interests of the Company and its stockholders. The Company believes that this compensation program appropriately satisfies the Company’s goals of establishing a compensation package that attracts and retains a strong, motivated leadership team, aligns the financial incentives of the executive officers with the interests of the stockholders, and rewards the achievement of specific annual, long-term, and strategic goals of the Company. The Company believes that the compensation program, which has been established and is reflected herein has enabled it to recruit and secure a talented and motivated leadership team by which the Company drives toward the ultimate objective of improving stockholder value.
