Many of our stockholders hold their shares through brokers, banks, or other nominees, rather than directly in their own names. As summarized below, there are some differences between being a stockholder of record and a beneficial owner of shares held in street name.

Stockholder of record:If your shares are registered directly in your name with PQ’sEcovyst’s transfer agent, American Stock Transfer andEquiniti Trust Company, LLC, you are the stockholder of record with respect to those shares and the proxy materials were sent directly to you. As the stockholder of record, you have the right to grant your voting proxy directly to the individualsindividual named on the proxy card and to vote at the Annual Meeting.

2018 PROXY STATEMENT

TABLE OF CONTENTS

Beneficial owner of shares held in street name: If your shares are held in a brokerage account or by a bank or other nominee, then you are the “beneficial owner of shares held in street name” and the proxy materials were forwarded to you by your broker, bank or other nominee, who is considered to be the stockholder of record. As a beneficial owner, you have the right to instruct the broker, bank or other nominee holding your shares how to vote your shares.

How do I vote?

There are four ways to vote:

In Person. You may vote in person at the Annual Meeting by requesting a ballot from an usher. If you are a beneficial owner of shares held in street name and wish to vote in person at the Annual Meeting, you must obtain a “legal proxy” from the broker, bank or other nominee that holds your shares. A legal proxy is a written document that authorizes you to vote your shares held in street name at the Annual Meeting. Please contact the broker, bank or other nominee that holds your shares for instructions regarding obtaining a legal proxy. You must bring a copy of the legal proxy to the Annual Meeting. In order for your vote to be counted, you must hand both the copy of the legal proxy and your completed ballot to an usher to be provided to the inspector of election.

Mail. You may vote by proxy by filling out your proxy card and returning it in the envelope provided.

All shares represented by valid proxies received prior to the taking of the vote at the Annual Meeting will be voted and, where a stockholder specifies by means of the proxy a choice with respect to any matter to be acted upon, the shares will be voted in accordance with the stockholder’s instructions. Even if you plan on attending the Annual Meeting in person,online, we encourage you to vote your shares in advance online, by phone, or by mail to ensure that your vote will be represented at the Annual Meeting.

Can I change my vote or revoke my proxy?

You may revoke your proxy and change your vote at any time before the taking of the vote at the Annual Meeting.

In Person. You may revoke your proxy and change your vote by attending the Annual Meeting and voting in person.

TABLE OF CONTENTS

What happens if I do not instruct how my shares should be voted?

Stockholders of record.If you are a stockholder of record and you:

indicate when voting online or by phone that you wish to vote as recommended by the Board; or
sign and return a proxy card without giving specific instructions,

then the personsperson named as proxy holders,holder, Joseph S. Koscinski, and William J. Sichko, Jr., will vote your shares in the manner recommended by the Board on all matters presented in this Proxy Statement and as theyhe may determine in theirhis best judgment with respect to any other matters properly presented for a vote at the Annual Meeting.

Beneficial owners of shares held in street name.If you are a beneficial owner of shares held in street name and do not provide the broker, bank or other nominee that holds your shares with specific voting instructions, then the broker, bank or other nominee that holds your shares may generally vote your shares in their discretion on “routine” matters, but cannot vote on “non-routine” matters.

What are routine and non-routine proposals?

The following proposal is considered a routine matter:

The ratification of the appointment of PricewaterhouseCoopers LLP as the independent registered public accounting firm of the Company for the fiscal year ending December 31, 20182024 (Proposal 4).

A broker, bank or other nominee may generally vote in their discretion on routine matters, and therefore no broker non-votes are expected in connection with Proposal 4.

The following proposals are considered non-routine matters:

Election of directors (Proposal 1);
Advisory vote on the say-on-pay proposal (Proposal 2); and
Advisory vote on the frequency of the say-on-pay proposaladvisory votes on executive compensation in the future (Proposal 3); and
The Charter Amendment (Proposal 5).

If the broker, bank or other nominee that holds your shares does not receive instructions from you on how to vote your shares on a non-routine matter, that broker, bank or other nominee will inform the inspector of election that it does not have the authority to vote on the matter with respect to your shares. This is generally referred to as a “broker non-vote.” Therefore, broker non-votes may exist in connection with Proposals 1, through 3.

2, 3 and 5.

What constitutes a quorum for the Annual Meeting?

The presence at the meeting, in persononline or by proxy, of the holders of Common Stock representing a majority of the shares outstanding and entitled to vote for the election of directors is necessary to constitute a quorum for all purposes.

What vote is required to approve each proposal?

Proposal 1: Election of directors. Directors are elected by a plurality of the votes cast. Therefore, if you do not vote for a nominee, or you “withhold authority to vote” for a nominee, your vote will not count either “for” or “against” the nominee.

Proposal 2: Advisory vote on the say-on-pay proposal. Generally, approval of any matter presented to stockholders (other than the election of directors) requires the affirmative vote of a majority of the votes cast on the matter. However, because this proposal asks for a non-binding, advisory vote, there is no “required” vote that would constitute approval.

Proposal 3: Advisory vote on the frequency of the say-on-pay proposaladvisory votes on executive compensation in the future.Because this proposal also calls for a non-binding, advisory vote, there is no “required” vote that would constitute approval. If none of the frequency options receives the vote of a majority of the votes cast on the matter, the option receiving the greatest number of votes will be considered the frequency recommended by the Company’s stockholders.

Proposal 4: Ratification of PwC.The affirmative vote of a majority of the votes cast is required to ratify the selection of PricewaterhouseCoopers LLP as the independent registered public accounting firm of the Company for the fiscal year ending December 31, 2018.

2024.

Proposal 5: The Charter Amendment. The Charter Amendment requires the affirmative vote of a majority of the outstanding shares of capital stock of the Company to be approved.
What effect will broker non-votes and abstentions have?

Broker non-votes and abstentions are counted as present and entitled to vote for purposes of determining whether a quorum is present. Broker non-votes and abstentions will have no effect on the outcome of each proposal.

Proposals 1, 2 and 3. No broker non-votes are expected in connection with Proposal 4. Broker non-votes and abstentions will have the same effect as an “against” vote on Proposal 5.

Who pays for costs relating to the proxy materials and Annual Meeting?

The costs of preparing, assembling and mailing this Proxy Statement, the proxy card and the Annual Report, along with the cost of posting the proxy materials on a website, are to be borne by us. In addition to the use of mail, our directors, officers and employees may solicit proxies personally and by telephone, facsimile and other electronic means.

AtCurrently, at each annual meeting of stockholders, directors in one class are elected for a full term of three years to succeed those directors whose terms are expiring. Greg Brenneman, Jonny GinnsAnna C. Catalano, Sarah Lorance and Kyle Vann are the current Class I directors whose terms expire at the Annual Meeting. Mr. Vann has decided not to stand for re-election in accordance with the Board’s Director Retirement Policy.
Our Board has nominated, and stockholders are being asked to re-elect, Messrs. Brenneman, Ginnselect, Ms. Catalano and VannMs. Lorance for three-year terms expiring at our 20212027 annual meeting of stockholders. The Board has also nominated Donald Althoff for election as a Class I director for a three-year term expiring at our 2027 annual meeting of stockholders.
Mr. Althoff, 67, has over 40 years of experience in the chemical and energy industries. From September 2019 to September 2022, he served as Director and Chairman of the Board of Vereson Midstream LP, and from September 2019 to December 2022, he served as Director of Alliance Pipeline and Aux Sable LP. From October 2017 to September 2019 he served as President and Chief Executive Officer of Veresen Midstream LP, and he served as President and Chief Executive Officer of Veresen Inc. from November 2012 to September 2017. From October 2008 to September 2012 he served as President and Chief Executive Officer at Flex Fuel. From 1981 to 2008, Mr. Althoff served in roles of increasing responsibility with Amoco Corporation and BP PLC. Mr. Althoff holds a Bachelor of Science in Chemical Engineering from the University of Illinois. Mr. Althoff was nominated for election to the Board as a result of his experience in the chemical and energy industries as well as his general business experience.
If elected, the nominees will each hold office until our 20212027 annual meeting of stockholders and a successor is duly elected and qualified or until earlier death, resignation, or removal.

The Board has included the proposed declassification of the Board via the Charter Amendment on the ballot for the 2024 annual meeting of stockholders (Proposal 5). If Proposal 5 is approved by our stockholders, we will begin a process of declassifying the Board, which will be completed at the 2027 annual meeting of stockholders. Following the 2027 annual meeting of stockholders, the Board will consist of one class elected to one-year terms.

Each of the above nominees has indicated his or her willingness to serve, if elected. However, if a nominee should be unable to serve, the shares of Common Stock represented by proxies may be voted for a substitute nominee designated by the Board. Management has no reason to believe that any of the above-mentioned persons will not serve his or her term as a director.

All of our nominees have served previously on our Board, which has provided them with significant exposure to both our business and the industry in which we compete.

We believe that all our nominees possess the professional and personal qualifications necessary for boardBoard service, and we have highlighted particularly noteworthy attributes for each director in the individual biographies below.

The Board recommends a vote FOR the election of each of the director nominees.

Governance Review and Governance Changes
As a result of the sale by CCMP, formerly our primary private equity sponsor, of the remainder of its stockholdings in the Company in 2023, our Board undertook a review of the Company’s corporate governance framework to determine if changes to our policies and practices were warranted. In conducting this review, the Board considered governance practices among similarly situated companies and took into consideration practices that are designed to provide for stockholders to have a greater voice in the governance of the Company. As a result of this review, the Board has included the Charter Amendment (Proposal 5) on the ballot for the 2024 annual meeting of stockholders. For more information about the Charter Amendment, please see Proposal 5.
Also in connection with the Board’s governance practices review and as a means of ensuring that the Board is comprised of highly qualified directors who bring new ideas and insights to the Board as a whole and to promote director refreshment, new perspectives, diverse views and independence among Board members, the Board in 2023 also amended the Company’s Corporate Governance Guidelines to incorporate a retirement and tenure policy with respect to directors. Pursuant to the retirement and tenure policy, upon reaching the age of 75, a director shall offer to resign from the Board and all committees thereof effective upon the completion of his or her then-current term, and the Nominating and Corporate Governance Committee shall review the continued appropriateness of that director’s membership on the Board under the circumstances and shall make a recommendation to the full Board as to whether to accept or decline such offer to resign. In addition, a non-employee director who has served on the Board for twelve (12) consecutive years shall offer to resign from the Board and all committees thereof effective upon the completion of his or her then-current term, and the Nominating and Corporate Governance Committee shall review the continued appropriateness of that non-employee director’s membership on the Board under the circumstances and shall make a recommendation to the full Board as to whether to accept or decline such offer to resign. The twelve (12) year service period is calculated beginning on the date the non-employee director first joined the Board (whether as a result of election by the Board to fill a director vacancy or election by the stockholders) or, if applicable, the date of Ecovyst’s initial public offering, whichever is later. Director Kyle Vann, having reached the age of 75 and being at the end of his current term as a director, is not standing for re-election in 2024 and will retire from the Board effective at the annual meeting of stockholders. Mr. Vann did not request, and the Board did not grant, a waiver of the retirement policy to allow him to serve another term on the Board.
In 2023, the Board also reviewed its existing process to conduct self-evaluations for the Board and each of its committees. As a result of this review, the Board instituted a more robust process in which Board and committee members anonymously complete questionnaires

that are designed to elicit feedback regarding the operations of the Board and its committees. The results of the consolidated questionnaires then were reviewed with the Board as a whole and were provided to the Board committees for their evaluation and potential action.
From time to time, the Board will continue to evaluate the governance structure for the Company and may make changes if they are deemed to be in the best interest of the Company and its stockholders.

Our Board’s Role in Risk Oversight
It is management’s responsibility to manage risk and bring to the Board’s attention risks that are material to Ecovyst. The Board has oversight responsibility for the systems established to report and monitor the most significant risks applicable to Ecovyst. The Board believes that evaluating the executive team’s management of the various risks confronting Ecovyst is one of its most important areas of oversight.
In accordance with this responsibility, the Board administers its risk oversight role directly and through its committee structure and the committees’ regular reports to the Board at Board meetings. The Board reviews strategic, financial and execution risks and exposures associated with the annual plan and long-term plans, material litigation and other matters that may present material risk to the Company’s operations, plans, prospects or the Company’s reputation, acquisitions and divestitures, senior management succession planning and enterprise risk management.
In connection with risk oversight, Board committees assist with the review, assessment and oversight of the Company’s risk management efforts. The chart below sets forth some examples of the roles Board committees play in risk oversight:
Committee
Risk Oversight Areas
Audit Committee
• The design, adequacy and effectiveness of our internal controls
• Review of our earnings releases and quarterly and annual report filings with the SEC
• Review of the Company’s enterprise risk management program and material risks identified as part of annual review of Company risks
• The integrity of the Company’s information technology systems, the adequacy of security measures taken to protect such systems and disclosure of material cyber incidents in accordance with SEC rules
Compensation Committee
• Whether the Company’s compensation policies and practices provide appropriate incentives to management or encourage undue risk-taking by management
• Applying, if necessary, the clawback provisions of the 2017 Plan and the Company’s Policy for Recoupment of Incentive Compensation, which was adopted by the Board to comply with SEC and NYSE requirements
• Administration and oversight of stock ownership requirement for directors and executive officers
• Establishment of CEO and other executive officer compensation based on performance reviews
Nominating and Corporate Governance Committee
• Compliance with ethical requirements, including avoidance of conflicts of interest
• Corporate public responsibility, including political contributions
Health, Safety, Environment and Security Committee
• Oversight of the Company’s programs and procedures to manage and mitigate HSES risks
• Ensuring that management recognizes and addresses emerging HSES issues and regulations
• Ensuring the Company conducts appropriate internal and external HSES auditing programs, assesses the results of such audits and implements corrective action for issues identified in such audits
Policy Against Hedging of Stock
Our insider trading policy prohibits our directors, officers and employees from entering into hedging or monetization transactions, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars and exchange funds, because such transactions may permit a director, officer or employee to continue to own securities obtained through our employee benefit plans or otherwise, but without the full risks and rewards of ownership. When that occurs, the individual may no longer have the same objectives as our other stockholders.

Enterprise Risk Management
In 2018, the Company implemented an Enterprise Risk Management process that is designed to identify, assess, mitigate and monitor the risks the organization faces. The process is guided by an ERM Charter, which sets forth the primary goals of the program and is overseen, internally, by a Risk Council that is comprised of members of the executive team as well as externally through the Audit Committee of the Board. In conducting the program, the Company engages in a series of risk identification workshops in its business units and functions, including finance, legal, environment and sustainability, health and safety, strategy and others. Upon completion of the workshops, the Company develops a listing of the identified risks and risk definitions. Those risks then are evaluated through a risk assessment process in which Company personnel assess the severity, likelihood and existing mitigation effectiveness relating to the identified risks. After compiling the results of the assessment process in 2023, management then conducted a “Teach-In” session with the Board to review the findings. In addition, individual risks are assigned to one or more “risk owners” who review the existing mitigation efforts and steps that should be taken to further mitigate the effects of such risks. Those risk owner reviews then are presented to the Audit Committee at its regularly scheduled meetings.
Board Refreshment, Diversity and Board Expertise
The Board believes it is a priority to engage in thoughtful, deliberate director refreshment that expands diversity in experience and critical perspectives in order to benefit all of Ecovyst’s stakeholders. As a result, six of our nine current Board members have joined the Board as directors since 2022.
We seek to have a Board that represents diversity as to experience, gender and ethnicity/race, but we do not have a formal policy with respect to diversity. We also seek a Board that reflects a range of talents, ages, tenures, skills, character and expertise, particularly in the areas of leadership, operations, risk management, accounting and finance, strategic planning and the industries in which we operate, sufficient to provide sound and prudent guidance with respect to our operations and interests.
Our Board currently is comprised of 9 members, and we believe their ages, experiences, gender and ethnic diversities and skills collectively bring a broad range of outlooks and talents to their services to the Company. For example, five of our current directors – or approx. 55% of the Board composition – bring gender or racial/ethnic diversity to the Board and a sixth member of our Board is an armed forces veteran. The illustrations below show the make-up of our current Board of Directors based on age, Board tenure, independence, and gender and racial/ethnic diversity.

Director Nominations

Criteria and Process of Identifying and Evaluating Candidates for Consideration as a Director Nominee

Under its charter, our Nominating and Corporate Governance Committee is responsible for recommending to the Board candidates to stand for election to the Board at the Company’s annual meeting of stockholders and for recommending candidates to fill vacancies on the Board that may occur between annual meetings of stockholders. The Nominating and Corporate Governance Committee may receive suggestions for new directors from a number of sources, including Board members and our Chief Executive Officer, and may also, in its discretion, employ a third-party search firm to assist in identifying candidates for director. The Corporate Governance Guidelines provide that each director should possess a combination of skills, professional experience and diversity of viewpoints necessary to oversee the Company’s business. It is the policy of the Board that directors should possess the highest personal and professional ethics, integrity and values, and be committed to representing the long-term interests of the Company’s stakeholders. Board members are expected to become and remain informed about the Company, its business and its industry and rigorously prepare for, attend and participate in all Board and applicable committee meetings. The Nominating and Corporate Governance Committee evaluates each individual in the context of the skills, character, diversity and expertise of the Board as a whole, with the objective of recommending a group that can best perpetuate the success of our business and represent stockholder interests through the exercise of sound judgment using its diversity of experience. In addition, the Nominating and Corporate Governance Committee considers, in light of our business, each director nominee’s experience, qualifications, attributes and skills that are identified in the biographical and other information contained in this Proxy Statement. Prior to the appointment of Ms. Lorance to the Board effective March 1, 2024 and the nomination of Mr. Althoff for election as a director at the annual meeting of stockholders, the Board considered a number of qualified candidates for these positions and ultimately selected Ms. Lorance and Mr. Althoff for appointment or nomination, as the case may be.

Board Leadership Structure

Under our Corporate Governance Guidelines, our Board may select a Chairperson at any time, who may also be an executive officertime. Prior to April 2022, the roles of the Company. Michael Boyce, our former non-executive Chairperson, retired from the Board in December 2017. At that time, James Gentilcore, our PresidentChairman and Chief Executive Officer assumedwere combined. In April 2022, the additional role ofBoard decided to decouple these positions, and therefore the Company’s Chief Executive Officer no longer serves as Chairman. Instead, a non-employee director, Mr. Fogarty, was elected as our Board Non-Executive Chairman in April 2022 and he continues to serve in that capacity. As non-Executive Chairman, Mr. Fogarty has the power to call meetings of the Board. Given Mr. Gentilcore’s extensive experienceindependent directors and deep knowledge of our Company and our industry, theto preside over such meetings. The Board believes that combiningutilizing a Non-Employee Chairman and the Chairperson and Chief Executive Officer positionsexercise of key Board oversight responsibilities by independent directors is currently the most effective leadership structure for PQ. As Chief Executive Officer, Mr. Gentilcore is intimately involved in the day-to-day operationsbest interest of our stockholders.
Classified Board Structure
Since our initial public offering, we have maintained a classified board structure in which directors are divided into three classes and one class is elected each year to serve a three-year term. The Board believed that this classified board structure promoted continuity and stability of strategy and encouraged a long-term perspective by Company management and facilitated the ability of the Board to focus on creating long-term stockholder value. With the exit of CCMP, formerly our primary private equity sponsor, in 2023, the Board reevaluated the classified structure and concluded that it would be in the best interests of the Company and is best positionedits stockholders to leadpropose the BoardCharter Amendment to phase in settingannual election of directors beginning in 2025, with the strategic focusdeclassification process being completed at the 2027 annual meeting of stockholders.

Policies Relating to Directors Service Retirement and Service

Tenure

It is our policy that a director other than the Chief Executive Officer, who is also an employee of the Company, shall offerbe deemed to have offered his or her resignation from the Board to the Nominating and Corporate Governance Committee at the same time he or she retires, resigns or resignsis terminated from employment with the Company. In addition, it is our policy that directors who retire or otherwise change from the principal occupation or background association they held when they were originally invited to the Board should provide notice to the Nominating and Corporate Governance Committee or the Board and offer to resign from the Board. The Board does not believe that such directors should necessarily leave the Board, but it is our policy that there should be an opportunity for the Board to review the continued appropriateness of such director’s membership under these circumstances.
The Board also believes that each director should advise the Nominating and Corporate Governance Committee in advance of accepting an invitation to serve as a member on another board of directors.

In general, the Board does not have a policy limiting the number of other public company boards of directors upon which a director may sit. However, the Nominating and Corporate Governance Committee shall consider the number of other boards of directors (or comparable governing bodies), particularly with respect to public companies, on which a prospective nominee is a member. Although the Board does not impose a limit on outside directorships, it does recognize the substantial time commitments attendant to membership on the Board and expects that directors devote all such time as is necessary to fulfill their accompanying responsibilities, both in terms of preparation for, and attendance and participation at, meetings.

Pursuant to our Audit Committee charter and the New York Stock Exchange listing rules, members may serve on no more than three separate public company audit committees simultaneously without prior review and determination by the Board that such simultaneous service would not impair the ability of such member to effectively serve on the Company’s Audit Committee.

As a means of ensuring that the Board is comprised of highly qualified directors who bring new ideas and insights to the Board as a whole and to promote director refreshment, new perspectives, diverse views and independence among Board members, the Board in 2023 amended the Corporate Governance Guidelines to incorporate a retirement and tenure policy with respect to directors. Pursuant to the retirement and tenure policy, upon reaching the age of 75, a director shall offer to resign from the Board and all committees thereof effective upon the completion of his or her then-current term, and the Nominating and Corporate Governance Committee shall review the continued appropriateness of that director’s membership on the Board under the circumstances and shall make a recommendation to the full Board as to whether to accept or decline such offer to resign. Director Kyle Vann, having reached the age of 75 and being at the end of his current term as a director, is not standing for re-election in 2024 and will retire from the Board effective at the annual meeting of stockholders. Mr. Vann did not request, and the Board did not grant, a waiver of the retirement policy to allow him to serve another term on the Board.
In addition, a non-employee director who has served on the Board for twelve (12) consecutive years shall offer to resign from the Board and all committees thereof effective upon the completion of his or her then-current term, and the Nominating and Corporate Governance Committee shall review the continued appropriateness of that non-employee director’s membership on the Board under the circumstances and shall make a recommendation to the full Board as to whether to accept or decline such offer to resign. The twelve (12) year service period shall be calculated beginning on the date the non-employee director first joined the Board (whether as a result of election by the Board to fill a director vacancy or election by the stockholders) or, if applicable, the date of Ecovyst’s initial public offering, whichever is later.
Communications with Directors

Stockholders and other interested parties may communicate directly with the Board, the non-employee directors or the independent directors as a group, or specified individual directors by writing to such individual or group c/o Secretary, PQ Group HoldingsEcovyst Inc., Valleybrooke Corporate Center, 300 Lindenwood Drive, Malvern, Pennsylvania 19355. The Secretary will forward such communications to the relevant group or individual at or prior to the next meeting of the Board.

Code of Conduct

We have adopted a written Code of Conduct applicable to all employees and a written Code of Ethics for Senior Executive and Financial Officers, which are designed to ensure that our business is conducted with integrity. These codes cover, among other things, professional conduct, conflicts of interest, accurate recordkeeping and reporting, public communications and the protection of confidential information, as well as adherence to laws and regulations applicable to the conduct of our business. We intend to disclose any future amendments to, or waivers from, these codes of ethics for PQ executive officers within four business days of the waiver or amendment through a website posting or by filing a Current Report on Form 8-K with the Securities and Exchange Commission.

SUSTAINABILITY
Sustainability is intertwined with our daily business and is reinforced through our strategy and values. We strive to create sustainable products that are safe for the environment, and to reduce waste and increase efficiencies for our customers and stakeholders. We believe that our products contribute to lower emissions and cleaner air, advance the global transition to clean energy, support the circular plastics economy and ensure clean, purified drinking water. We are committed to creating environmentally responsible products that we believe make a difference in people’s daily lives and for our planet.
While offering products and services that help our customers to advance their own sustainability goals, we also work to advance our commitment to maintain sound environmental, social and governance (“ESG”) practices, policies and procedures. For example, we:

Continued work towards our recently announced series of 2025 and 2030 sustainability goals with respect to fuel usage, power usage, health, safety and environment performance, and community engagement;
Introduced our employees to our core values Stewardship, High Standards, Integrity and Engagement (“SHINE”) and in 2023, provided training on these values and provisions of our Code of Conduct, completing training for approximately 99.8% of active employees in 2023;
Continued steps to implement additional improvements in a number of areas, including health, safety and environmental (“HSE”) performance; commitment to diversity, inclusion and human rights both within our company and in our supply chain; and ethical and lawful business practices;
Further integrated a corporate-wide sustainability software platform, which we are utilizing as an internal, real-time sustainability performance dashboard to enable improved analytics and greater visibility into our sustainability impacts; and
Achieved a greater than 90% performance in our flagship HSE Perfect Days program, which targets at-risk behaviors and celebrates positive HSE performance across the organization on a daily basis.
The sections that follow provide some highlights of our environmental, social, and governance programs and procedures.
Environmental Stewardship. Our products and technologies continue to address our customers’ sustainability challenges, tightening global regulatory standards and changing consumer preferences. In our Ecoservices segment, we provide sulfuric acid regeneration services that avoid significant landfill or deep well disposal of spent, or used, sulfuric acid. In our Advanced Materials & Catalysts segment, our zeolite catalysts are used for cleaner air applications and our advanced silicas are key for light weighting and plastics recycling.

Executive Summary

2017 Compensation Decisions

In connection with the Company’s initial public offering in September 2017, we made certain changes to our executive compensation programs as follows:

Base salary: Consistent with our compensation philosophy of providing competitive levels of executive compensation, each of our
Stock ownership requirements for named executive officers received base salary increases after we reviewed market pay levels.to align with stockholder interests
Incentive compensation payouts tied to key performance metrics tied to business results and stockholder returns
Hold a “say-on-pay” stockholder advisory vote on an annual basis
Forbid short sales, hedging or pledging transactions involving Company securities
Make compensation decisions utilizing a group of appropriate peer companies
Incentive compensation clawback policy aligns with SEC and NYSE requirements
Provide an appropriate mix of short- and long-term incentive compensation
Compensation programs designed to discourage undue or excessive management risk-taking
Our executive compensation philosophy is to provide compensation that:
Long-Term Incentive Awards: Each
Aligns the interests of our named executive officers received a grant of time-vesting options and restricted stock units shortly after our initial public offering. These grants were made in part as a retention vehicle to keep our team intact during the critical period of time following the offering, and also to recognize the significant contributions that each of our named executive officers made to the success of our offering. We expect that no additional long-term incentive awards will be made in 2018, and that in 2019 we will again grant long-term incentive awards to our executive officers.

In addition, with respectour stockholders’ interests by rewarding performance that is designed to 2017,create stockholder value; and

Provides an annual incentive payment was made toamount and mix of total compensation for each of our named executive officers underthat is market competitive.
We seek to implement our pay philosophy by providing a total compensation package that includes three main components: base salary, annual performance-based bonus and long-term equity-based awards. The Compensation Committee takes into account individual performance and competitive market practice in determining the PQIP, ourcompensation package for each named executive officer. The peer group for making 2023 compensation decisions was changed at the end of 2022, because several peers used for 2022 compensation decisions were acquired and other companies were substituted to take their place. This peer group is disclosed below and labelled “2023 Compensation Peer Group”.
Base salary has been set with a view toward attracting, retaining and motivating executive officer talent. The Compensation Committee also takes into account market-competitive base salary rates relative to Ecovyst’s 2023 compensation peer group and each executive’s level of experience functioning in their particular roles.
Our annual incentive plan, described below,the Ecovyst Incentive Plan or “EIP”, is a broad-based plan under which annual performance-based cash opportunities are awarded to our named executive officers and other employees, and which, for 2023, based pay outs on the achievement of annual Adjusted EBITDA, Adjusted Free Cash Flow, safety and environmental goals.
Our long-term equity-based awards currently consist of Restricted Stock Units (“RSUs”) that are subject to time-vesting conditions and Performance Stock Units (“PSUs”) that are subject to performance-based vesting conditions. The PSUs granted in 2023 were tied to goals related to absolute Total Shareholder Return (“TSR”) performance over a three-year performance period. Each of these elements of compensation is discussed in more detail below.
We believe that our executive compensation program is strongly aligned with the interests of our stockholders:
Taking into account the results of recent say-on-pay advisory votes and utilizing market-based compensation among our peer group, the Compensation Committee has made changes to our named executive officers’ overall compensation in 2023 and 2024 to align with our peers and to reflect the size and complexity of the Company and the experience of incumbents in each position.
By providing a substantial portion of our named executive officers’ total compensation package in the form of equity-based awards, we have emphasized variable pay over fixed pay, strengthening the alignment between our named executive officers and our stockholders by creating an incentive to build stockholder value over the long-term.
Our PSUs are earned based on the Company’s achievement of specific financial performance metrics.

the achievement of share value creation. Grants made from 2021-2024 utilize performance metrics which are substantially or completely based on TSR.
Our annual performance-based cash incentive is contingent upon the achievement of financial performance goals. The amount of bonus compensation ultimately received varies with our annual financial performance, thereby providing an additional incentive to produce results that are designed to be tied to stockholder value.
Corporate Governance and Best Practices

What We Do
Peer Group Adjustment
The Compensation Committee reviews and adjusts the peer group on an annual basis to determine the appropriateness of the peer group listing. As a result of merger and acquisition activity involving five peers in the 2022 compensation peer group, the Compensation Committee took action to replace those peer companies with five new peers within the compensation peer group for 2023.
Pay for performancePerformance
Consistent with our goal of creating a performance-oriented environment, a substantial portion of executive pay is based on the achievement of specific strategic and financial goals orand the price performance of our Common Stock. Our long-term incentive performance metrics have been adjusted to include a 100 percent weight Total Shareholder Return (“TSR”) metric in the 2021, 2022, and 2023 PSU grants. In our 2024 PSU grants, a 50 percent weight Cumulative Adjusted EBITDA metric has been incorporated, and a relative TSR metric at an adjusted weight of 50 percent also was utilized.
Equity vesting on account of ordinary severance or severance due to a change in control
No automatic vesting of equity occurs on either event.
Stock ownership guidelines
Our Chief Executive Officer must hold shares of Company stockour Common Stock having a value of at least 5X base salary, and the other named executive officers must hold shares of Company stockour Common Stock having a value of at least 3X base salary. We believe that this stock holding requirement creates alignment of our executive management team with the interests of our stockholders. Our named executive officers have five years to comply with our stock ownership guidelines and are required to retain at least 50% of the after-tax shares received from equity awards until the required ownership levels are achieved.
Clawback
Our named executive officers, in certain circumstances, would be required to return the value of equity awards if our financial statements are restated as a result of their wrongdoing. Additionally, our named executive officers would be required to return any gain received in connection with the exercise, vesting, payment or other realization of income related to an equity award in the event of a breach of any non-solicitation, non-interference or confidentiality obligations or violation of our Code of Conduct. We have incorporated the adjustments to our clawback policies that are required to comply with the new SEC and NYSE requirements.
Independent Compensation Consultant
The Compensation Committee retains an independent compensation consultant that provides no other services to the Company.

We provide a modest supplemental retirement opportunity tied to the statutory caps in our 401(k) plan.

Say on Pay Advisory Vote

The Compensation Committee takes seriously the ability of stockholders to weigh in on our compensation decisions through a “say on pay” advisory vote. At this Annual Meeting, which will be our first as a public company, we will ask stockholders to (1) approve, on an advisory basis, a voting cycle whereby say on pay is on the ballot every year and (2) consider the Company’s financial performance and pay structure and provide us with a favorable advisory vote on 2017 compensation for named executive officers.

Executive Compensation Program Philosophy and Overview

Our compensation philosophy is to provide pay that:

Aligns the interests of our named executive officers with our stockholders’ interests by rewarding performance that is tied to creating shareholder value; and
Provides an amount and mix of total compensation for each of our named executive officers that we believe is competitive.

We seek to implement our pay philosophy by providing a total compensation package that includes three main components: base salary, annual performance-based bonus and long-term equity-based awards. The Compensation Committee takes into account individual performance and competitive market practice in determining the compensation package for each named executive officer. A compensation peer group has been formed with the assistance of our independent compensation consultant, and this peer group is referenced in the discussion below. We utilized the peer group as a tool in making compensation decisions for 2017, and we expect to continue to utilize one when making compensation decisions going forward.

Base salary has been set with a view toward attracting and retaining executive officer talent.

Our annual incentive plan (the “PQIP”) is a broad-based plan under which annual performance-based cash opportunities are awarded to our named executive officers and other employees, and which, for 2017, paid based on the achievement of annual EBITDA goals.

Our long-term equity-based awards consist of stock options, restricted shares, and restricted stock units that are subject to time and/or performance vesting conditions. The long-term equity-based awards made prior to our September 2017 initial public offering were made in amounts intended to be competitive for private equity backed ventures in the specialty chemicals space. The size of grants made immediately following our initial public offering was determined with reference to peer group data, as well as other relevant factors, including the need to keep our executive team together following the offering.

Each of these elements of compensation is discussed in more detail, below.

We believe that our executive compensation program is strongly aligned with the interests of our stockholders:

For several years before our September 2017 initial public offering, our named executive officers and senior leadership team have been significant owners of the Company, and we expect this to continue.
Our named executive officers and senior leadership team have been offered the opportunity to purchase equity in the Company over the last several years, in addition to receiving equity as a form of incentive compensation.
By providing a substantial portion of our named executive officers’ total compensation package in the form of equity-based awards, we have been able to create an incentive to build shareholder value over the long-term.
By weighting our named executive officers’ compensation more heavily in favor of long-term incentive compensation, including time- and performance-vesting stock options, restricted shares, and restricted stock units, we have built a strong “pay for performance” culture.
Our annual performance-based bonus is contingent upon the achievement of financial performance metrics and the amount of bonus compensation ultimately received varies with our annual financial performance, thereby providing an additional incentive to maximize shareholder value.

We will continue to promote share ownership and a strong pay for performance culture. We believe that this philosophy has been successful in motivating, retaining and incentivizing our named executive officers and providing value to our stockholders.

Compensation Decision Making Process

Role of the Compensation Committee and Management

During 2017,2023, the Compensation Committee was responsible for the oversight, implementation and administration of all our executive compensation plans and programs. None of the named executive officers had any role in approving the compensation of the other named executive officers. However, the Compensation Committee does consider the recommendations of our Chief Executive Officer in setting compensation levels for our named executive officers other than our Chief Executive Officer.himself. The Compensation Committee solely determined all components of the compensation of our Chief Executive Officer.

On an annual basis, the Compensation Committee reviews compensation for theour named executive officers in conjunction with performance evaluations, salary increase recommendations, determination of bonus payouts,pay outs and deliberations regarding long-term incentive grants. The Compensation Committee has conducted, and willplans to continue to conduct, annual reviews of our executive compensation program to ensure that it remains alignedits continued alignment with our compensation philosophy. The Compensation Committee will continue to make decisions taking into account good governance best practices regarding compensation, including reliance on market data for the chemical and specialty chemical industryindustries, and theall other considerations mentioneddescribed in this Compensation Discussion and Analysis.

The 2023 EIP performance grids set forth below were established by the Compensation Committee for the named executive officers in December 2022. While the EIP covers most management and professional employees in the organization, the goals of most participants outside of our named executive officers are business-unit specific.
In order to receive any payment on the Adjusted EBITDA and Adjusted Free Cash Flow portion of the Company-wide EIP performance metrics, the Company had to achieve an Adjusted EBITDA of at least $273 million in 2023. Adjusted EBITDA and Adjusted Free Cash Flow are non-GAAP financial metrics. An explanation of how we calculate these metrics is provided below.

TABLE OF CONTENTS


Following are the reasons the Company uses these metrics in the EIP, along with definitions of the metrics used.
Metric/Goal
Reason for Inclusion in the EIP
Adjusted EBITDA
Adjusted EBITDA is the most significant indicator of financial operating performance. Improvements in financial operating performance are directly linked to sustainable share value creation.
Adjusted Free Cash Flow
Adjusted Free Cash Flow is an important indicator of operating efficiency (e.g., the ability to increase margins by careful management of operating expenses) and management of capital expenditures. Improvements in Adjusted Free Cash Flow also equip the Company to pursue new opportunities. Increased operating efficiency and the successful pursuit of new opportunities lead to share value creation.
HSE Perfect Days
There is a direct link between an improving safety and environmental incident record, and higher worker productivity and sustained share value creation.
Recordable Incident Rate
This is a measurable indicator, tied to compensation, measuring the Company’s commitment to continuing to evolve our safety culture in our drive to be best-in-class.
Metric/Goal
Definition
Adjusted EBITDA
EBITDA consists of net income (loss) attributable to the Company before interest, taxes, depreciation and amortization. Adjusted EBITDA consists of EBITDA adjusted for (i) non-operating income or expense, (ii) the impact of certain non-cash, non-recurring or other items included in net income (loss) and EBITDA that we do not consider indicative of our ongoing operating performance, and (iii) depreciation, amortization and interest of our 50% share of the Zeolyst Joint Venture.
Adjusted Free Cash Flow
Adjusted Free Cash Flow consists of cash flow from operating activities less purchases of property, plant and equipment plus proceeds from asset sales plus net interest proceeds on cross-currency swaps.
HSE Perfect Days
“HSE Perfect Days” is the number of days without a significant safety or environmental incident.
Recordable Incident Rate
“Recordable Incident Rate” represents the rate of recordable incidents, as reflected on our OSHA Form 300 log per 100 full-time employees annually.
The target annual performance-based cash award opportunity for each eligiblenamed executive officer was set as a percentage of annualized base salary (i.e., actual base salary paid during 2017)2023). The target award percentages for each of our named executive officers remainedFor 2023, the same for 2017 as in 2016. For 2017, theactual target award percentages were as follows:

For 2017, the PQIP was structured to base the awardThe level of performance actually achieved on the performance of our two operating segments:

Performance Materials & Chemicals Group
Environmental Catalysts & Services Group

For Messrs. Gentilcore, Crews and Koscinski, awards under the PQIP were based on the achievementa Company-wide basis for 2023 in each of the annual EBITDA targets for the two operating segments:

Performance Materials & Chemicals Group – 50%four categories was as follows:
Environmental Catalysts & Services Group – 50%

For Messrs. Randolph and Ferrall, awards under the PQIP were based on the achievement of the EBITDA target for their respective operating segment:

Mr. Randolph – 100% Performance Materials & Chemicals Group
Mr. Ferrall – 100% Environmental Catalysts & Services Group

To the extent that an operating segment achieved at least 95% of its annual EBITDA target, a threshold bonus of 25% of the target bonus attributable to that operating segment was earned. To the extent that an operating segment achieved at least 99% of its annual EBITDA target, the full portion of the named executive officer’s target bonus attributable to that operating segment was earned.

To the extent that the Company exceeded 100% of its annual EBIDTA target (set forth below), an above-target pool was created. The above target pool was a dollar amount equal to 25% of the Company’s EBITDA above target.

Executives who were eligible to participate in the above target pool were allocated a portion of the above target pool as follows:

Long-Term Equity Based Incentive Awards

In connection with our initial public offering, our Board adopted the 2017 Plan.

Since the time of theour initial public offering, all of our equity-based awards have been and going forward will continue to be, granted under the 2017 Plan. Our equity incentive awards currently consist of restricted shares, restricted stock units, and options to purchase shares of our Common Stock.

In keeping with our pay for performance culture, the options and restricted shares granted prior to our initial public offering partially vest based on time, partially vest based on performance and partially vest on both time and performance. The performance vesting terms are described in more detail below.

Of the time-vested restricted shares and stock options issued prior to our initial public offering under the PQ Group Holdings, Inc. StockOmnibus Incentive Plan (the predecessor plan toor the 2017 Plan), most ofOmnibus Incentive Plan, as amended and restated (collectively, the “2017 Plan”). Those awards vest ratably over a period of three years. Several awards vest in 50% increments in two and four years. All of these awards are subject to accelerated vesting upon a change in control.

The performance-basedhave included time-vesting RSUs, time-vesting stock options, and performance-based restricted shares currently outstanding are all unvestedperformance-vesting PSUs tied to both financial performance and will only vest on the achievement with respect to shares of Company Common Stock of an average closing trading price equaleither absolute or exceeding, in any 10 trading day period, the lowest amount which, when multiplied by the number of shares of Company Common Stock then held by investment funds affiliated with CCMP and added to the aggregate net proceeds received by investment funds affiliated with CCMP with respect to their shares of capital stock of the Company, would yield a quotient of equal or greater than two when divided by the equity investment in the Company by investment funds affiliated with CCMP. relative TSR goals.

The quotient described above is referred to in this Compensation Discussion and Analysis as the “MOI Target.”

Grants in 2017

Long-term2023 long-term equity-based incentive awards were made to Mr. Gentilcore in January 2017 to correct a shortfall in the initial new hire grants that were made to him when he commenced employment with us (the grant date value of which had been initially determined using a target value that assumed a lower base salary than Mr. Gentilcore actually receives). The Companywe granted Mr. Gentilcore an option to purchase 21,494 shares of Common Stock and 6,090 restricted shares. A portion of these awards vest ratably over three years, and a portion only vests on the achievement of the MOI Target described above, as further detailed in the notes to the Grants of Plan Based Awards table below.

In addition, shortly after our initial public offering in September, the Company made equity awards to our named executive officers included a mix of time-vesting RSUs and performance-vesting PSUs. The number of PSUs that were granted in 2023 and which are subjecteligible to time-based vesting,be earned is tied to the achievement of absolute TSR targets over the three-year performance period ending December 31, 2025.

Grants Made in 2023
In December of 2022, the Compensation Committee determined that it was advisable to make another grant of long-term equity incentive awards to its named executive officers, and designeddid so on January 16, 2023. The equity incentive awards were in the form of time vested RSUs and performance vested PSUs.
For 2023, the Committee determined that it was appropriate to encourage their retention. Thoseweight such grants for all named executive officers except Mr. Bitting as 50 percent RSUs and 50 percent PSUs. In the case of Mr. Bitting, however, 65 percent of his grant consisted of PSUs, and 35 percent consisted of RSUs. For all named executive officers, RSUs vest ratably over a three-year period and PSUs vest at the conclusion of a three-year performance period if the performance metrics are achieved. The awards granted were as follows:

2023 PSU Design
In setting the 2023 PSU design, the Compensation Committee continued to focus on the Company’s share price performance. In doing so, four factors were taken into account for the grants made in 2023.
First, the Compensation Committee continued the use of absolute TSR as the sole performance metric for PSUs.
Second, the Compensation Committee adjusted the weighting of time vesting RSUs and PSUs for all named executive officers. This resulted in an equity mix of 35 percent RSUs / 65 percent PSUs for Mr. Bitting, and 50 percent RSUs / 50 percent PSUs for Messrs. Feehan, Koscinski, Vann and Whittleston.
Third, the Compensation Committee set threshold at 18 percent absolute TSR over the three-year performance period, set target at 30 percent absolute TSR over the three year performance period, and set maximum at 80 percent absolute TSR over the three year performance period. Based on input from our compensation consultant, 80 percent TSR performance would place the Company at around the 75th percentile of our peer group in terms of absolute TSR performance.

Changes to Our Annual Plan Structure for 2018; 2018 Equity Awards

PQIP

Fourth, the Compensation Committee determined that the use of PSUs further down the organization would foster a results-based performance culture that is designed to yield improvement in share price performance. Therefore, it was decided that grants below the CEO and senior executive level of at least $100,000 but less than $250,000 would consist of 60 percent time vesting RSUs and 40 percent performance-based PSUs.
The Company has decided to make several changes to2023 PSU grants will vest, if at all, at the PQIP in 2018, consistent with its status as a publicly traded business. Someend of the important changes are:

Allthree-year performance period which runs from January 1, 2023 to December 31, 2025. The sole performance metric is absolute TSR. Absolute TSR is defined as the financial gain that results from a change in the price of our named executive officers’ awards will be based ona company’s stock during the Company’s performance as a whole, versus operating segmentperiod plus any dividends paid by the company during the performance
Performance will be based on Company adjusted EBITDA goals and, in addition, a cash flow goal and a leadership goal
A minimum adjusted EBITDA threshold must be met before any component amounts will be paid out under period divided by the PQIP
Amounts above target may be earned in eachprice of the three categoriescompany’s stock at the beginning of goalsthe performance period.

Grants Made in 2024
The Compensation Committee determined to make long-term equity-based incentive awards in 2024, and those awards were granted on January 22, 2024. For the named executive officers, the Compensation Committee strongly believed that it was important to more heavily weight performance in the vesting criteria and, therefore, decided to utilize a mix of 60 percent PSUs and 40 percent RSUs for all named executive officers except for Mr. Bitting, who received a grant consisting of 65 percent PSUs and 35 percent RSUs. PSUs would vest, if at all, at the conclusion of a three-year performance period ending December 31, 2026 and RSUs would vest ratably over a three-year period. In our 2024 PSU grants, a 50 percent weight cumulative Adjusted EBITDA metric has beeen incorporated, and a relative TSR metric at an adjusted weight of 50 percent also was utilized.

Stock Ownership Guidelines for Executive Officers and Non-Employee Directors

In connection with

Under our initial public offering, the Compensation Committee adopted stock ownership guidelines, applicable to our executive officers including our named executive officers, and our non-employee directors. Under our stock ownership guidelines,directors, each of our named executive officers, other than our Chief Executive Officer, is expected to have ownership of Company stockour Common Stock in an amount equal to at least three times the executive’snamed executive officer’s annualized base salary, and our Chief Executive Officer is expected to have ownership of Company stockour Common Stock in an amount equal to at least five times his annualized base salary. Under our stock ownership guidelines, each of our non-employee directors is expected to have ownership of Company stock in an amount equal to at least three times the annual cash retainer paid to the director.
Executive officers and non-employee directors subject to the guidelines will have five years to achieve the required ownership levels and, until they satisfy their ownership requirements, will beare subject to a holding requirement with respect to 50% of the shares of Common Stock they acquire upon the vesting or exercise of shares or stock optionstheir equity-based awards (on an after-tax basis).

Tax Considerations

Section 162(m) of the Internal Revenue Code (“Section 162(m)”) generally limits the deductibility of compensation paid to our named executive officers to $1 million during any fiscal year. However, under a Section 162(m) transition rule for compensation plans or agreements of corporations which are privately held and which become publicly held in an initial public offering, compensation paid under a plan or agreement that existed prior to the initial public offering will not be subject to Section 162(m) until the earliest of (1) the expiration of the plan or agreement, (2) a material modification of the plan or agreement, (3) the issuance of all employer stock and other compensation that has been allocated under the plan, or (4) the first meeting of stockholders at which directors are to be elected that occurs after the close of the third calendar year following the year of the initial public offering (the “Transition Date”).

Prior to January 1, 2018, certain compensation that qualified as “performance-based” was exempted from the above deductibility limits under Section 162(m). However, the Tax Cuts and Jobs Act of 2017 generally eliminated the performance-based compensation exception, with certain limited grandfathering provisions,provisions.

Bitting, Feehan, Koscinski, Vann, and Whittleston in 20172023, Messrs. Bitting, Feehan, Koscinski, and 2016,Vann in 2022, and Messrs. Bitting, Feehan, and Koscinski in 2021, computed in accordance with FASB ASC Topic 718, in each case, disregarding the effects of estimated forfeitures. These amounts reflect our cumulative accounting expense over the vesting period, disregarding the effects of estimated forfeitures, and do not correspond to the actual value that may be realized by the named executive officers. For information on the valuation assumptions made in the calculation of these amounts, refer to Note21 to the audited consolidated financial statements in our Form 10-K for the fiscal year ended December 31, 2017 and2022, Note 2123 to the audited consolidated financial statements in our Form 10-K for the prospectus filedfiscal year ended December 31, 2022, and Note 23 to the audited consolidated financial statements in connection with our initial public offering.Form 10-K for the fiscal year ended December 31, 2021. With respect to stock options and restricted shares that are subject to performance-based vesting conditions,the PSUs, the aggregate grant date fair value was determined based on the probable outcome of the performance conditions associated with such awards at the date of grant. For performance-based stock options,PSUs, the aggregate grant date fair value of these awards assumes performance at 100% of target. The aggregate grant date fair value of the PSU awards assuming the maximum level of performance is achieved, is: Mr. Gentilcore’s 2017 and 2016Bitting’s 2023 grants $43,824 and $358,311, respectively; and$4,863,092; Mr. Crews’ 2016Feehan’s 2023 grant $152,300. For performance-based restricted shares, the aggregate$1,246,951; Mr. Koscinski’s 2023 grant, date fair value of these awards, assuming the maximum level of performance is achieved, is:$1,496,327; Mr. Gentilcore’s 2017 and 2016Vann’s 2023 grant, $810,507; Mr. Whittleston’s 2023 grants, $39,177 and $374,959, respectively; and Mr. Crews’ 2016 grant, $159,482.$810,507.

Retirement Plan Benefits

We maintain the Ecovyst 401(k) Savings Plan, a tax-qualified 401(k) defined contribution plan, in which substantially all of our full-time U.S. employees, including our named executive officers, are eligible to participate. We currently provide an employer contribution equal to 4% of qualifying earnings and an employer matching contribution equal to 50% of a participant’s contributions up to 6% of qualifying earnings, subject to limits established by the Internal Revenue Code. As described in more detail below, our named executive officers participate in the PQ CorporationEcovyst Non-Qualified Personal Retirement Account Excess Savings Plan, an excess benefit plan designed to provide supplemental contributions that cannot be provided under our 401(k) plan due to Internal Revenue Code limits. We believe these plans provide our named executive officers with an opportunity for tax-efficient savings and long-term financial security.

Nonqualified Deferred Compensation

All of our named executive officers participate in the PQ CorporationEcovyst Non-Qualified Personal Retirement Account Excess Savings Plan, or the PRA SERP. The PRA SERP is an excess benefit plan designed to provide supplemental Personal Retirement Account contributions that cannot be provided under the PQ Corporation Savings Plan (the Company’sour 401(k) plan)plan due to Internal Revenue Code limits. The plan is administered by a committee appointed by our Board.

the board of directors of Ecovyst Advanced Materials and Catalysts LLC.

ContributionsThere are no executive contributions under the PRA SERP. Each plan year, we credit to participant accounts under the PRA SERP the excess of (a) the amount that would have been credited for that year to the participant’s Personal Retirement Account under our 401(k) plan disregarding the dollar limits imposed by the Internal Revenue Code for maximum annual compensation over (b) the amount that was actually so credited. The plan administrator may from time to time also elect to make special contributions to participant accounts.

Earning and lossesParticipant accounts are deemed to be invested in Vanguard target retirement funds based on a participant’s age. At the end of each calendar quarter, we adjust participant accounts with earnings/losses equal to that calendar quarter’s return for the applicable target retirement fund.

Vesting and distributionsParticipants vest in their accounts under the PRA SERP upon completion of three years of service or, if earlier, upon the participant’s death or disability or a change in control. The value of a participant’s vested account balance is paid in a

CEO Pay Ratio
(3)Reflects the accelerated vesting of any unvested stock options and restricted shares that would have vested upon termination or a change of control pursuant to the terms of the award agreements governing such unvested awards outstanding as of December 31, 2017, assuming a price per share of $16.45, which was the closing price of a share of our Common Stock on December 29, 2017, the last business day of fiscal year 2017, as reported on the NYSE. No amounts have been included in respect of performance-based stock options or restricted shares since the MOI Target associated with such awards would not have been satisfied at these shares prices.
As required by SEC rules, we are providing the following information about the relationship of the annual total compensation of our employees and the annual total compensation of our Chief Executive Officer. This pay ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K. Because the SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices, the pay ratio reported by other companies may not be comparable to the pay ratio reported below.
The median of the annual total compensation of all employees in our Company for 2023, except for our Chief Executive Officer, was $116,632. We would note that the median employee we used for the 2022 CEO Pay Ratio was no longer employed at the end of 2023, and we substituted an employee with substantially similar compensation for the 2023 CEO Pay Ratio calculation because we believe that there was no change in our employee population or employee compensation arrangements that would significantly affect the 2023 CEO Pay Ratio calculation. Specifically, we chose the employee whose 2023 compensation was substantially similar to the actual

TABLE OF CONTENTS


median employee used for 2022 based on the same compensation measure originally used to identify such employee. The total annualized compensation for our Chief Executive Officer for 2023 was $5,292,498. The resulting 2023 ratio of annual total compensation of our Chief Executive officer to the median of the annual total compensation of all of our other employees is estimated to be 31.76:1.
We chose a measurement date of December 31, 2023 for identifying our median employee. We examined the annual base salary or base rate of pay of all our employees, excluding our Chief Executive Officer, who were employed by us on December 31, 2023. We included all U.S. and non-U.S. employees who worked full-time, part-time or as interns. The use of annual base salary or base rate of pay is a consistently applied compensation measure that we believe reasonably reflects the compensation for our employee population.
In the cases where a full-time or a regular scheduled part-time employee was employed on December 31, 2023, but was not employed by the Company for all of 2023, the base salary or base rate of pay was annualized. Regular scheduled part-time employees were not converted into full-time equivalents. Annual base salary or base rate of pay, as applicable, includes overtime, shift premium, vacation and paid sick time. The base salaries or base rates of pay of non-U.S. employees were converted into U.S. dollars using the Company’s internal year to date average exchange rates.
After identifying the median employee based on the above methodology, we calculated that individual’s total annual compensation using the same methodology set forth in the 2023 Summary Compensation Table in this Proxy Statement.

PROPOSAL 2 — ADVISORY VOTE ON EXECUTIVE COMPENSATION

As required by Section 14A of the Securities Exchange Act of 1934, we are offering our stockholders an opportunity to cast an advisory vote on the compensation of our named executive officers, as disclosed in this proxy statement.Proxy Statement. Although the vote is non-binding, we value continuing and constructive feedback from our stockholders on compensation and other important matters. Our Board and the Compensation Committee expect to consider the voting results when making future compensation decisions.

As described in the “Compensation Discussion and Analysis” section of this proxy statement,Proxy Statement, we believe that our executive compensation program enables us to attract, retain, and motivate a high-performing executive management team that improves our fundamental financial performance and provides value to the Company and its stockholders.

We ask for your advisory vote on the following resolution:

“RESOLVED, that the stockholders hereby approve the compensation of PQ Group Holdings,Ecovyst Inc.’s named executive officers, as described in this proxy statementProxy Statement pursuant to the compensation disclosure rules of the Securities and Exchange Commission.”

Generally, approval of any matter presented to stockholders requires the affirmative vote of the holders of a majority of the shares of Common Stock represented at the Annual Meeting and voting on the matter. However, because this vote is advisory and non-binding there is no “required” vote that would constitute approval.

Your Board unanimously recommends that you vote “FOR” approval of this proposal.

PROPOSAL 3—3 — ADVISORY VOTE ON THE FREQUENCY OF THE VOTEADVISORY VOTES ON EXECUTIVE COMPENSATION

IN THE FUTURE

As required by Section 14A of the Securities Exchange Act of 1934, as amended, we are offering our stockholders an opportunity to cast an advisory vote on whether afuture non-binding stockholder advisory votevotes on the compensation of our named executive officers should occur every one, two or three years. Although the vote is non-binding, we value continuing and constructive feedback from our stockholders on compensation and other important matters. Our Board and the Compensation Committee intend to take into consideration the voting results when determining how often afuture non-binding stockholder advisory votevotes on the compensation of our named executive officers should occur.

We last held a stockholder advisory vote on the frequency of say-on-pay proposals in 2018, when stockholders recommended that a stockholder advisory votes on executive compensation occur every year. The Board has included a stockholder advisory vote on executive compensation on the annual meeting ballot each year since 2018.

Our Board has determined that continuing to hold an advisory vote on executive compensation every year is the best approach for the Company based on a number of considerations, including the vote frequency that our Board believes the majority of our investors prefer.

Stockholders are not voting to approve or disapprove of our Board’s recommendation. Instead, the proxy card provides stockholders with four choices with respect to this proposal: (1) one year, (2) two years, (3) three years or (4) abstaining from voting on the proposal. For the reason discussed above, we are asking our stockholders to indicate their support for thefuture non-binding advisory votevotes on executive compensation to be held every year.

Generally, approval of any matter presented to stockholders requires the affirmative vote of the holders of a majority of the shares of Common Stock represented at the Annual Meeting and voting on the matter. However, because this vote is advisory and non-binding, there is no “required” vote that would constitute approval. If none of the frequency options receives the vote of a majority of shares of Common Stock represented at the Annual Meeting and voting thereon, the option receiving the greatest number of votes will be considered the frequency recommended by the Company'sCompany’s stockholders.

Your Board unanimously recommends that you vote One“One Year” with respect to how frequently afuture non-binding stockholder vote votes on executive compensation should occur.

In addition, we evaluate whether PQ’sEcovyst’s use of PwC for permitted non-audit services is compatible with maintaining PwC’s independence and objectivity. After review of the non-audit services provided, we concluded that PwC’s provision of these non-audit services, all of which were approved in advance, is compatible with its independence.

PROPOSAL 5
AMENDMENT TO THE SECOND RESTATED CERTIFICATE OF INCORPORATION TO DECLASSIFY THE BOARD OF DIRECTORS
The Company has a classified board structure in which directors are divided into three classes, and directors in a class are elected each year to serve three-year terms.
After careful consideration, the Board has determined that it is advisable and in the best interests of the Company and its stockholders to amend the Charter to declassify the Board to allow the Company’s stockholders to vote on the election of the entire Board on an annual basis, and for such declassification to be phased in gradually over a two-year period starting with the election of directors in 2025. If the Charter is amended pursuant to the declassification proposal, following the two-year transition period, the Company’s stockholders will vote on the election of the entire Board on an annual basis. The Board has approved an amendment to the Charter to phase-out the Company’s classified Board. The amendment is included in Exhibit A to this Proxy Statement.
If the declassification proposal is approved by our stockholders, the declassification process will take place as follows: at the Annual Meeting, the stockholders will approve an amendment to the Charter eliminating the classified board structure; at the 2025 Annual Meeting of Stockholders, each of the Class II directors will be elected to a one-year term as a Class III director; at the 2026 Annual Meeting of Stockholders, each of the Class III directors will be elected to a one-year term as a Class I director; and at the 2027 Annual Meeting of Stockholders (and at each annual meeting thereafter), each director will be elected to a one-year term.
In addition, Delaware law provides that directors serving on boards that are not classified may be removed with or without cause, whereas currently, under the Charter, directors may be removed only for cause. As required by Delaware law, the proposed amendment would also permit stockholders to remove directors with or without cause beginning in 2027 when the Board is declassified.
The Board has historically believed that a classified board structure promotes continuity and stability of strategy and facilitates the ability of the Board to focus on creating long-term stockholder value. The Board is aware that the current trend in corporate governance is leading away from classified boards in favor of electing all directors annually and also recognizes that a classified board structure may reduce directors’ accountability to stockholders because such a structure does not enable stockholders to express a view on each director’s performance by means of an annual vote. Moreover, many institutional investors believe that the election of directors is the primary means for stockholders to influence corporate governance policies and to increase accountability for implementing those policies.
In determining whether to support the declassification of the Board, the Board carefully considered the advantages and disadvantages of the current classified board structure and has determined that it is advisable and in the best interest of the Company and its stockholders to declassify the Board.
The foregoing is a summary of the proposed amendment to the Charter and is qualified in its entirety by reference to the full text of the amendment to the Charter included in Exhibit A.
A quorum being present, the affirmative vote of a majority of the outstanding shares of capital stock of the Company is necessary to approve this declassification proposal. Broker non-votes and abstentions are counted as present and entitled to vote for purposes of determining whether a quorum is present. Broker non-votes and abstentions will have the same effect as an “against” vote on this declassification proposal. If the proposal is approved by our stockholders, the Certificate of Amendment to our Charter will become effective immediately upon its filing with the Secretary of State of the State of Delaware, which we expect to file promptly after the Annual Meeting. If the proposal is not approved by our stockholders, the Charter would remain unchanged.
The Board recommends a vote FOR Proposal 5, Amendment to the Second Restated Certificate of Incorporation to Declassify the Board of Directors
