~~2021~~2022 PROXY STATEMENT

TABLE OF CONTENTS

INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

Although we encourage you to read this Proxy Statement in its entirety, we include this Q&A section to provide some background information and brief answers to several questions you might have about the Annual Meeting.

Why are we providing these materials?

Our Board is providing these materials to you in connection with our Annual Meeting, which will be a virtual meeting conducted exclusively via live webcast at http://www.virtualshareholdermeeting.com/~~PQG2021~~ECVT2022 on ~~April 29, 2021~~May 26, 2022 at 9 a.m. (Eastern Time). Stockholders are invited to attend the Annual Meeting online and are requested to vote on the proposals described herein.

What information is contained in this Proxy Statement?

This Proxy Statement contains information relating to the proposals to be voted on at the Annual Meeting, the voting process, the compensation of our directors and most highly paid officers, and other required information.

What proposals will be voted on at the Annual Meeting?

There are three proposals scheduled to be voted on at the Annual Meeting:

the election of the four Class III director nominees specifically named in this Proxy Statement, each to serve for a term of three years;

an advisory vote on the say-on-pay proposal; and

the ratification of PricewaterhouseCoopers LLP as the independent registered public accounting firm of the Company for the fiscal year ending December 31, ~~2021.~~2022.

We will also consider other business properly brought before the Annual Meeting.

Can I attend the Annual Meeting?

~~In light of the ongoing public health and travel safety concerns related to the coronavirus (COVID-19) pandemic, the~~The Company has determined to again hold a virtual annual meeting in order to facilitate stockholder attendance and participation by enabling stockholders to participate from any location and at no cost.

To participate in the virtual meeting, you will need the control number included on your proxy card or voting instruction form. The meeting webcast will begin promptly at 9 a.m. (Eastern Time). We encourage you to access the meeting prior to the start time. Online check-in will begin at 8:45 a.m. (Eastern Time), and you should allow ample time for the check-in procedures. If you encounter any difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support number that will be posted on the Virtual Shareholder Meeting log in page.

We are committed to ensuring that stockholders will be afforded the same rights and opportunities to participate as they would at an in-person meeting. You will be able to attend the meeting online, vote your shares electronically and submit questions during the meeting by visiting http://www.virtualshareholdermeeting.com/~~PQG2021.~~ECVT2022. We will try to answer as many stockholder-submitted questions as time permits that comply with the meeting rules of conduct. However, we reserve the right to edit inappropriate language or to exclude questions that are not pertinent to meeting matters or that are otherwise inappropriate. If we receive substantially similar questions, we will group such questions together and provide a single response to avoid repetition.

What shares can I vote?

You may vote all shares of Common Stock that you owned as of the close of business on the record date, ~~March 8, 2021.~~April 21, 2022. You may cast one vote per share, including shares (i) held directly in your name as the stockholder of record and (ii) held for you as the beneficial owner through a broker, bank, or other nominee. The proxy card will indicate the number of shares that you are entitled to vote.

As of April 21, 2022, there were 138,696,941 shares of Common Stock outstanding, all of which are entitled to be voted at the Annual Meeting.

~~2021~~2022 PROXY STATEMENT

TABLE OF CONTENTS

~~As of March 8, 2021, there were 136,935,636 shares of Common Stock outstanding, all of which are entitled to be voted at the Annual Meeting.~~

A list of stockholders will be available at our headquarters at Valleybrooke Corporate Center, 300 Lindenwood Drive, Malvern, Pennsylvania 19355 for a period of at least ten days prior to the Annual Meeting. A list of stockholders will also be available electronically on the virtual meeting website during the meeting.

What is the difference between being a stockholder of record and a beneficial owner of shares held in street name?

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’s~~Ecovyst’s transfer agent, American Stock Transfer and 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 individuals named on the proxy card and to vote at the Annual Meeting.

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:

By attending the Annual Meeting Online. During the Annual Meeting, you may vote online by following the instructions at http://www.virtualshareholdermeeting.com/~~PQG2021.~~ECVT2022. Have your proxy card or voting instruction form available when you access the virtual meeting webpage.

Online. You may vote by proxy by visiting www.proxyvote.com and entering the control number found on your proxy card. The availability of online voting may depend on the voting procedures of the broker, bank or other nominee that holds your shares.

Phone. You may vote by proxy by calling the toll free number found on your proxy card. The availability of phone voting may depend on the voting procedures of the broker, bank or other nominee that holds your shares.

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 online, we encourage you to vote your shares in advance 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.

By Attending the Annual Meeting Online. You may revoke your proxy and change your vote by attending the Annual Meeting online and voting electronically during the meeting. However, your attendance online at the Annual Meeting will not automatically revoke your proxy unless you properly vote electronically during the Annual Meeting or specifically request that your prior proxy be revoked by delivering a written notice of revocation prior to the Annual Meeting to ~~PQ’s~~Ecovyst’s Secretary at 300 Lindenwood Drive, Malvern, Pennsylvania 19355.

Online. You may change your vote using the online voting method described above, in which case only your latest internet proxy submitted prior to the Annual Meeting will be counted.

Phone. You may change your vote using the phone voting method described above, in which case only your latest telephone proxy submitted prior to the Annual Meeting will be counted.

~~2021 PROXY STATEMENT~~

~~TABLE OF CONTENTS~~

Mail.You may revoke your proxy and change your vote by signing and returning a new proxy card dated as of a later date, in which case only your latest proxy card received prior to the Annual Meeting will be counted.

2022 PROXY STATEMENT

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 persons named as proxy holders, 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 they may determine in their 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, ~~2021~~2022 (Proposal 3).

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 3.

The following proposals are considered non-routine matters:

Election of directors (Proposal 1); and

Advisory vote on the say-on-pay proposal (Proposal 2).

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 and 2.

What constitutes a quorum for the Annual Meeting?

The presence at the meeting, online 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: 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, ~~2021.~~2022.

~~2021 PROXY STATEMENT~~

~~TABLE OF CONTENTS~~

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 Proposals 1 2 and 2. No broker non-votes are expected in connection with Proposal 3.

2022 PROXY STATEMENT

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

In addition to the use of mail, our directors, officers and employees may solicit proxies personally and by telephone, facsimile and other electronic means. They will receive no compensation in addition to their regular salaries. We may request banks, brokers and other custodians, nominees and fiduciaries to forward copies of the proxy materials to their principals and to request authority for the execution of proxies.

BOARD OF DIRECTORS

PROPOSAL 1

ELECTION OF DIRECTORS

PQEcovyst has a classified Board currently consisting ~~four directors with terms expiring in 2021 (Class I), four~~of five directors with terms expiring in 2022 (Class II) ~~and three~~, five directors with terms expiring in 2023 (Class III) and four directors with terms expiring in 2024 (Class I). 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. ~~Belgacem Chariag, Greg Brenneman, Johnny Ginns~~Robert Coxon, Mark McFadden, Susan F. Ward, Bryan K. Brown, and ~~Kyle Vann~~Christopher Behrens are the Class III directors whose terms expire at the Annual Meeting. Mr. Behrens will not stand for re-election following the expiration of his term. Our Board has nominated, and stockholders are being asked to re-elect, Ms. Ward and Messrs. ~~Chariag, Brenneman, Ginns~~Coxon, McFadden, and ~~Vann~~Brown for three-year terms expiring at our ~~2024~~2025 annual meeting of stockholders. If elected, the nominees will each hold office until our ~~2024~~2025 annual meeting of stockholders and a successor is duly elected and qualified or until earlier death, resignation, or removal.

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 board 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.

The following table sets forth the name, age and class, as of ~~March 1, 2021,~~April 29, 2022, of individuals who currently serve as directors on our Board.

Name	Age	Position	Class
~~Belgacem Chariag~~Kevin M. Fogarty	5856	Chairman ~~President and CEO~~	Class I

CORPORATE GOVERNANCE

General Governance Framework

The framework for the governance of our Company is set forth in our Second Restated Certificate of Incorporation (as amended and corrected), our Second Amended and Restated Bylaws, the charters of the Committees of our Board and our Corporate Governance Guidelines.

Our Corporate Governance Guidelines set forth a series of governance practices that we believe promote effective oversight of the Company. Among other things, these guidelines provide for:

the criteria for membership on the Board, including the requirement for the independence of directors as required by the standards of the New York Stock Exchange and the desirable skills that members of the Board should possess;

the compensation to be paid to Board members and the requirement that a portion of Board Members’ compensation be in the form of Company stock or stock-based instruments in order to align with the interests of stockholders;

regular meetings of non-management directors;

access by the Board to members of management and to outside advisers, as appropriate; and

the Board’s evaluation of its performance on an annual basis.

The Board also has adopted a Code of Conduct that applies to the Board and all employees of the Company and a Code of Ethics for Senior Executive and Financial Officers, both of 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. In accordance with SEC rules, we intend to disclose any future amendments (other than any technical, administrative, or non-substantive amendment) to, or waivers from, the codes applicable to the Company's Senior Executive and Financial 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 SEC. Additional information regarding these and other governance guidelines and practices is set forth below, and the documents referred to in this General Governance Framework are available on the Management and Governance section of our Investor Relations website at https://investor.ecovyst.com.

Board Structure, Meetings and Executive Sessions

Our Board currently consists of 14 members, with Mr. Fogarty serving as Chairman of the Board and Mr. Walsh as Lead Independent Director, and will consist of 13 members following our Annual Meeting. Our Board and its committees meet periodically throughout the year, as needed, to oversee management of the Company’s business and affairs for the benefit of its stockholders. During ~~2020, our Board substantially increased the number of meetings it held in order to provide effective oversight during the rapidly evolving COVID-19 pandemic. As such,~~2021, the Board held 11seven meetings and also approved certain actions by unanimous written consent. During ~~2020,~~2021, each director except for Mr. Currie attended at least 75% of the Board meetings and the total meetings held by all of the committees on which he or she served during the periods that he or she served. We encourage, but do not require, our directors to attend annual meetings of stockholders.

Consistent with our Corporate Governance Guidelines, our Board and its committees are afforded access to such of our employees as the Board deems necessary to effectively oversee the management of the Company. At each of our regularly scheduled Board meetings, our business unit Presidents, our Chief Financial Officer, our Vice President of Health, Safety, Environment and Sustainability, our Vice President of Technology and Business Development, our Chief Administrative Officer (who oversees human resources matters) and our General Counsel, are available to and regularly provide our Board and its committees with information regarding their respective businesses and functions and the Board members have the opportunity to pose questions to such executives. As applicable, members of the executive management team and other employees of the Company (including, but not limited to, our Director of Internal Audit, our Treasurer, our Controller and our Vice President of Tax) also attend meetings of the Board committees and provide information to such committees regarding their respective functions.

2022 PROXY STATEMENT

TABLE OF CONTENTS

Also consistent with our Corporate Governance Guidelines, the Board and its committees have the opportunity to engage outside advisers to provide such advice as the Board or its committees requires to effectively oversee the management of the Company.

Periodically throughout the year, the non-employee and independent directors meet in executive session without members of management present. These meetings allow such directors to discuss issues of importance to the Company, including the business and affairs of the Company and matters concerning management, without any member of management present. ~~The Board has selected Timothy~~Mr. Walsh, in his capacity as Lead Independent Director, ~~to preside at~~presides over all such meetings of non-employee and independent directors. During 2021, the non-employee and independent directors met without management present on three occasions.

Committees and Committee Composition

During fiscal ~~2020,~~2021, the Board had four standing committees: the Audit Committee, the Compensation Committee, the Nominating and Corporate Governance Committee, and the Health, Safety, Environment and ~~Environment~~Security Committee. The members of each committee are appointed by the Board and serve until their successor is elected and qualified, unless they are earlier removed or resign. Consistent with our Corporate Governance Guidelines, the Board takes into consideration the particular skills of Board members when appointing members to each standing committee. In addition, from time to time, special committees may be established under the direction of the Board when necessary to address specific issues.

The chairpersons of the standing Board committees regularly provide reports to the full Board regarding the topics of discussions of their respective committee meetings and actions taken at such committee meetings.

Compensation Committee Interlocks and Insider Participation

None of our executive officers serves as a member of the board of directors or compensation committee, or other committee serving an equivalent function, of any other entity that has one or more of its executive officers serving as a member of our Board or Compensation Committee. Mr. Walsh is employed by CCMP and Mr. Currie is employed by INEOS. For additional information regarding transactions between CCMP and its affiliates and us and between INEOS and its affiliates and us, see “Transactions with Related Persons.”

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 ~~PQ.~~Ecovyst. The Board has oversight responsibility for the systems established to report and monitor the most significant risks applicable to ~~PQ.~~Ecovyst. The Board believes that evaluating the executive team’s management of the various risks confronting PQEcovyst 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, major 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. ~~The Audit Committee oversees~~

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.

Board Independence

Our Corporate Governance Guidelines provide that our Board shall consist of such number of directors who are independent as is required and determined in accordance with applicable laws and regulations and requirements of the New York Stock Exchange and Securities and Exchange Commission rules. Under our Corporate Governance Guidelines, an “independent” director is one who meets the qualification requirements for being an independent director under applicable laws and the corporate governance listing standards of the New York Stock Exchange. Our Board evaluates any relationships between each director or nominee and PQEcovyst and makes an affirmative determination whether or not such director or nominee is independent. As a result of this review, our Board has affirmatively determined that each current member of our Board, with the exception of Mr. ~~Chariag,~~Bitting, our ~~Chairman, President and~~ Chief Executive Officer, is independent under the corporate governance listing standards of the New York Stock Exchange.

Diversity and Board Expertise

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, 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 14 members, and we believe their ages, experiences, gender and ethic diversities and skills collectively bring a broad range of outlooks and talents to their services to the Company. For example, three of our directors – or 21% of the Board – bring gender or ethnic diversity to the Board. The illustrations below show the make-up of our Board based on age, Board tenure, independence, and gender and ethnic diversity.

We also strive to recruit and retain qualified directors who bring a diversity of thought and experience to our Board. The chart below shows certain of the various skills and experiences that our Board believes are important to the oversight of the Company and the number of Board members who bring such skill or experience to the Board.

Board and Committee Annual Performance Reviews

Our Corporate Governance Guidelines provide that the Nominating and Corporate Governance Committee is responsible for reporting annually to the Board an evaluation of the overall performance of the Board. In addition, the written charters of the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee provide that each such committee shall evaluate its performance on an annual basis using criteria that it has developed and shall report to the Board on its findings. The Board and each committee of the Board conducts such performance reviews on an annual basis.

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 President and 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.

Board Leadership Structure

Under our Corporate Governance Guidelines, our Board may select a Chairperson at any ~~time, who may also be an executive officer~~time. In prior years, the roles of Chairman and Chief Executive Officer were combined. The Board has decided to decouple these positions, and therefore the ~~Company.~~Company’s Chief Executive Officer no longer serves as Chairman. Instead, a non-employee director will serve as Chairman. The Board elected Mr. ~~Chariag was elected~~Fogarty as our Board Chairman in December 2019. The Board believes that combining the Chairperson and Chief Executive Officer positions is currently the most effective leadership structure for PQ. As Chief Executive Officer, Mr. Chariag is intimately involved in the day-to-day operations of our Company and is best positioned to lead the Board in setting the strategic focus and direction for our Company.April 2022. The Board has also named Timothy Walsh as Lead Independent Director. In this role, Mr. Walsh has the power to call meetings of the independent directors and to preside over such meetings. The Board believes that the ~~combination of the Chairman and Chief Executive Officer roles as part~~appointment of a ~~governance structure that includes~~non-employee Chairman and a Lead Independent Director, as well as the exercise of key Board oversight responsibilities by independent directors, ~~provides an effective balance for the management of the Company~~is currently in the best 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 believes that this classified board structure promotes continuity and stability of strategy, encourages a long-term perspective by Company management, because a majority of directors will always have experience as directors of the Company, and facilitates the ability of the Board to focus on creating long-term stockholder value.

Succession Planning

The Chief Executive Officer reviews succession planning and management development with the Board and the Nominating and Corporate Governance Committee on an annual basis. This succession planning includes the development of policies and principles for selection of the Chief Executive Officer, including succession in the event of an emergency or retirement.

Majority Voting Guidelines

Our Corporate Governance Guidelines provide that in an uncontested election of directors, any nominee for director who receives a greater number of votes “withheld” from his or her election than votes “for” such election shall promptly tender his or her resignation following certification of the stockholder vote. The Board shall determine whether or not to accept such resignation within a period of 120 days following the stockholder vote, and will promptly publicly disclose its decision to accept or reject the resignation and the reasons for doing so.

Policies Relating to Directors and Service

It is our policy that a director, other than the Chief Executive Officer, who is also an employee of the Company, shall offer his or her resignation from the Board to the Nominating and Corporate Governance Committee at the same time he or she retires or resigns 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.

~~2021 PROXY STATEMENT~~

~~TABLE OF CONTENTS~~

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.

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 Holdings~~Ecovyst Inc., 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.

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, 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, in 2021 we:

Elevated the position of Vice President – Health, Safety, Environment and Sustainability to an executive-level management position that now reports directly to our CEO;

Created an executive-level ESG Leadership Team, which is led by our CEO, to oversee the Company’s sustainability goal-setting and efforts to achieve the established goals;

Developed and announced a series of sustainability goals with respect to greenhouse gas emissions, waste management and reduction, product sustainability/R&D investment and company certifications by 2025 and 2030;

Undertook a review of our internal policies and procedures to identify and 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;

Implemented a corporate-wide sustainability software platform, which we plan to utilize as an internal, real-time sustainability performance dashboard to enable improved analytics and greater visibility into our sustainability impacts;

We achieved a 91% HSE Perfect Days performance across the company in 2021, mirroring our 2020 performance and a vast improvement since 2019 after the program started in 2018, as shown below:

Achieved a Silver Sustainability Score from EcoVadis, a third-party sustainability evaluation company, prior to the sale of Performance Chemicals. The Silver Score from EcoVadis places us in the 91st percentile of all companies ranked by EcoVadis in our sector group; and

Concluded 2021 with no material environmental and safety incidents, and our recordable injury rate, which was in the top quartile of our American Chemistry Council (“ACC”) peer companies in 2021, has improved from 2017 levels as shown in the chart below:

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 while enabling the manufacture of cleaner and efficient fuels. In our Catalyst Technologies segment, our zeolite catalysts are used for cleaner air applications and our silica catalysts are key for light weighting and plastics recycling. Our innovation investment ratio on new sustainable products has gone from 60% in 2015 to 85% in 2021.

As part of our sustainability commitment regarding our own operations, we apply the principles of the Environmental Management standard of the International Organization for Standardization (ISO 14001) at our facilities throughout the world. For chemical facilities in the United States, we also adhere to the Responsible Care® RC14001 Technical Specifications of the ACC.

We maintain policies and procedures to monitor and control health, safety, and environmental risks, and to monitor compliance with applicable state, national, and international health, safety, and environmental requirements. We have comprehensive health, safety and environmental compliance, auditing and management programs in place to assist in our compliance with applicable regulatory

requirements and with internal policies and procedures, as appropriate. Each facility has developed and implemented specific critical occupational health, safety, environmental, security and loss control programs.

We also have a strong health, safety and environmental organization staffed by professionals who are responsible for environmental, safety, health and product regulatory compliance. Our HSE organizational structure features executive management level leadership, active oversight by our Board and dedicated environmental experts on staff. We have Regional HSE Specialists and Managers who are embedded in the field and provide HSE expertise and support to operating sites. Certain, larger sites may have dedicated environmental or safety personnel.

As an ACC Responsible Care® member company, we continue to monitor and report our health, safety, and environmental metrics annually. Our sustainability metrics, including waste generation and water consumption for 2018 and 2019, were third party assured for the first time in 2020. In 2021, we reviewed our 2020 sustainability metrics and successfully underwent third party verification of this data as well. We expect to include the assured 2020 data on our web-site and in our next Sustainability Report, which we expect to publish in the second quarter of 2022.

We also have established a Product Safety and Product Stewardship management system that is compliant with the RC14001 technical specification and is supported by a highly skilled Product Stewardship Manager. We conduct Product Stewardship reviews as part of new product development and routinely evaluate product safety risk for raw materials, intermediates, and finished products.

Social Responsibility. We seek to act in a socially responsible manner through our various HSE programs as described above, our commitment to building a diverse and inclusive workforce, engagement with and support for the communities where we live and work, and advancement of socially responsible business practices through partnerships and other industry frameworks.

We are committed to providing equal employment opportunities for all employees and applicants for employment, and do not discriminate on the basis of race, color, religion, sex, sexual orientation, pregnancy, gender identity and expression, national origin, disability, age (40 or above), ancestry, genetic information, marital status, veteran status or any other classification protected by law. This commitment applies to all terms and conditions of employment including recruiting, hiring, placement, advancement, training, transfer, demotion, lay off and recall, termination, compensation and benefits.

It is our policy to comply with all applicable laws and regulations in each jurisdiction in which we operate in order to provide appropriate working conditions for our colleagues. This means that we comply with applicable laws regarding the employment relationship including those that (1) prohibit child labor, (2) set acceptable working conditions and working hours, (3) provide for fair wages, including minimum wages and overtime, (4) prohibit forced or bonded labor, (5) permit freedom of association and collective bargaining, and (6) prohibit discrimination, harassment and other forms of degrading or inhumane treatment. Using tools such as our Supplier Code of Conduct and contractual provisions, we also hold our business partners to these same standards.

Our flagship “Success through People” program furthers our strategy by acknowledging our workforce is key to our success. We offer highly competitive salaries, benefits, developmental opportunities and work/life balance. We proactively seek to attract, incentivize and retain a talented and motivated workforce. Our global succession planning process is designed to provide sufficient talented personnel to fill key leadership, innovation and manufacturing roles well into the future and to better prepare employees for their future at the Company. In order to enable a pipeline for our leadership, we maintain a robust Emerging Leaders program to identify top talent to build leadership capabilities and provide the fundamental skills we believe every leader needs to generate passion and productivity in their team. The program also provides an important networking opportunity that creates a connected community of leaders at the Company.

We review our compensation and benefits programs periodically to ensure continued competitiveness. In the U.S., our benefit program is designed to help protect the health and financial well-being of our full-time employees and their family members today, offering a choice of several medical & dental plans, as well as vision, flexible spending accounts, short-term and long-term disability insurance and an employee assistance program. To help them prepare for their future, we offer a defined contribution savings plan, which includes company contributions. Benefits outside the U.S. are designed to supplement government-provided programs in each country.

We actively promote gender, racial and ethnic diversity within the Company, seek to have a workforce that reflects the diversity of the societies in which we operate and we believe we benefit from our talented, dedicated and diverse employee population. As of

2022 PROXY STATEMENT

TABLE OF CONTENTS

December 31, 2021, we had 883 employees worldwide, of which 766 were employed in the United States and the remainder outside of the United States. Further, at December 31, 2021, approximately 25% of our U.S.-based executives, managers and professionals were females and 16% were non-white males.

Among our seven-member executive management team, one brings gender diversity to our executive ranks. Another two of our executives are veterans of the U.S. armed forces. One of our armed forces veterans also is disabled.

As of December 31, 2021, approximately 35% of our employees were represented by a union, works council or other employee representative body. We believe we have good relationships with our employees and their respective works councils, unions or other bargaining representatives.

Our commitment to our workforce, supported by our core values of integrity and fairness, fosters a rich culture founded on diversity of thought. We firmly believe that success is achieved through the intellect and commitment of our people, so we employ a long-term human capital program to attract, retain and develop talent for the future. We are proud of our highly collaborative teams that enable an inclusive workplace where employees are encouraged to bring their own experiences to promote innovation from all levels of the organization. This constructive work environment has been re-enforced with the recent implementation of a fully integrated on-line performance management process that improves the communication of aligned goals, encourages consistent feedback and furthers employee engagement. We also have gender diversity on the management teams of each of our businesses as well as in all our functions: Research and Development, Finance, HSE and Human Resources.

While the continuing COVID-19 pandemic has limited the opportunities for in-person engagement in our communities, our sites continued to work to have a positive impact in the communities in which we operate. For example, in 2021 (a) our office in The Woodlands, Texas delivered donated board games, blankets, and other goods to the Montgomery County Community Action Center and also donated canned goods and packed Thanksgiving boxes at the Montgomery County Assistance Center, (b) our Houston, Texas plant made a food donation to a local church, (c) our Hammond, Indiana plant conducted a toiletry drive for disadvantaged people, and (d) our Baytown, Texas plant delivered turkeys to a local elementary school to be delivered to local families in need and also performed volunteer hours at the local chamber of commerce in support for a holiday “Cards for Troops” initiative.

Governance. We maintain and consistently reinforce within our organization a series of policies and practices designed to ensure that decisions made on behalf of our company are properly made and executed. Some of our corporate governance policies and programs are described in the earlier sections of this Proxy Statement. Our governance programs and policies start with a strong tone at the top and are summarized in our Executive Statement on Ethics and Compliance, which has been distributed throughout the organization.

The principles set forth in the Executive Statement are codified in our Code of Conduct, which sets forth the legal and ethical standards to which our employees must adhere, including (a) acting with integrity, (b) avoiding actual or apparent conflicts of interest, (c) complying with the rules and regulations of federal, state, provincial, local governments, and other appropriate regulatory agencies, (d) complying with all rules and regulations prohibiting fraud, bribery, corrupt practices, anti-competitive activities and trading with embargoed persons and countries, (e) complying with all company policies and procedures, and (f) actively promoting ethical behavior in the workplace. We provide annual training on our Code of Conduct to all our global employees and have enhanced our delivery with online learning modules.

The Company’s Ethics section of the sustainability webpages, which is routinely updated and includes a description of our enterprise risk management program and our policies on child labor, human trafficking, anti-harassment, antibribery, and cyber security all of which are evaluated by third-parties, including EcoVadis.

In addition, we will be required to bear the registration expenses, other than underwriting discounts and commissions and transfer taxes, associated with any registration of shares described above and to indemnify such stockholders and certain other persons against certain liabilities that may arise under the Securities Act in connection with any such offering and sale of our shares. CCMP exercised its rights with respect to such offering and sale of its shares of our common stock on two occasions in 2021.

Policies and Procedures for Related Party Transactions

Our Board has adopted a written policy with respect to the review, approval and ratification of related party transactions.

~~Executive Summary~~

~~2020 Compensation Decisions~~

In 2019, the Compensation Committee determined to make certain changes to the base salaries of most of our named executive officers, effective beginning in 2020. The decision to do so was based on market data, the performance of the incumbents, and the fact that base salary had not been adjusted for these named executive officers since 2017 (and for Messrs. Chariag and Kolberg since their dates of hire, 2018 and 2016, respectively). These changes are detailed, below.

~~No changes were made in 2020 to the percentage of base pay which constitutes the target annual incentive for each of our named executive officers.~~

In December 2021, the Compensation Committee determined to raise the annual incentive opportunity of Mr. Koscinski from 55 percent of base pay to 65 percent of base pay. Also, in December 2021, the Compensation Committee determined to make ~~adjustments~~certain changes to the ~~performance metrics in our annual incentive plan (the “PQIP”) for 2020, relative~~base salaries of Messrs.

Mr. Schneberger was appointed President on April 27, 2022. In connection with these changes, the Board determined to make changes to their compensation, effective as of May 1, 2022. Mr. Bitting and Mr. Schneberger each received a base salary increase to $500,000 per year, and their target annual incentive opportunity was raised to 100 percent of base salary.

~~The Compensation Committee will continue to track the economic impact of COVID-19 in 2021, and may adjust performance goals in the future, if it deems appropriate.~~

TABLE OF CONTENTS

Corporate Governance and Best Practices

	What We Do
	Pay for performance			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 or the performance of our Common Stock. Our “pay for performance” culture was further strengthened with the introduction of TSR as a metric in the 2020 and 2021 PSU ~~grant~~grants and the continued use of TSR in the ~~2021~~2022 grant.
	Equity vesting on account of a change in control			No automatic vesting of equity occurs in the event of a change in control. There is no “single trigger” vesting on a change in control; i.e., vesting whether or not the holder of non-vested equity loses his or her job. Moreover, if there is a change in control and an equity holder loses his or her job, there is no vesting of non-vested equity.
	Stock ownership guidelines			Our Chief Executive Officer must hold shares of our Common Stock having a value of at least 5X base salary, and the other named executive officers must hold shares of our 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.
	Independent Compensation Consultant			The Compensation Committee retains an independent compensation consultant that provides no other services to the Company.

~~2021 PROXY STATEMENT~~

~~TABLE OF CONTENTS~~

	What We ~~Don’t~~Don't Do
	No rich supplemental retirement plan benefits are offered			We provide a modest supplemental retirement opportunity tied to the statutory caps in our 401(k) plan.
	No change in control excise tax gross ups			In accordance with what we believe are good governance best practices, we provide no change in control excise tax gross-ups.
	No short-term trading, short sales, hedging or pledging			As part of our policy on insider trading and communications with the public, all of our employees, including our named executive officers, as well as our directors and consultants, are prohibited from engaging in speculative transactions in our stock, including short sales, puts/calls, hedging transactions and margin accounts or pledges.
	No annual incentives for named executive officers absent performance			Minimum hurdles must be satisfied before our named executive officers can earn any annual cash incentive compensation.

Say on Pay Advisory Vote

The Compensation Committee takes seriously the ability of stockholders to weigh in on our executive compensation decisions through an annual “say on pay” advisory vote. At the April ~~30, 2020~~29, 2021 Annual Meeting of Stockholders, stockholders approved, on an advisory basis, the compensation paid by us to our named executive officers. Approval was secured by 99more than 98 percent of the votes cast.

2022 PROXY STATEMENT

TABLE OF CONTENTS

This year, we are again asking stockholders to consider our executive compensation program and provide us with a favorable advisory vote on the compensation for our named executive officers.

Executive Compensation Program Philosophy and Overview

Our executive compensation philosophy is to provide compensation that:

Aligns the interests of our named executive officers with our stockholders’ interests by rewarding performance that is tied to creating ~~shareholder~~stockholder 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 ~~2020,~~2021, and we expect to continue to utilize ~~one~~an appropriate peer group when making compensation decisions going forward. The Compensation Committee periodically reviews the composition of the peer group, and makes changes, as appropriate. ~~As discussed in more detail below, changes were made to the peer group for the 2020 fiscal year.~~

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

Our annual incentive plan, ~~(the “PQIP”)~~the 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 ~~2020, paid~~2021, based payouts on the achievement of annual ~~adjusted~~Adjusted EBITDA, ~~adjusted free cash flow,~~Adjusted Free Cash Flow, and safety goals.

~~2021 PROXY STATEMENT~~

~~TABLE OF CONTENTS~~

Our long-term equity-based awards currently consists of ~~restricted stock units~~RSUs that are subject to time vesting conditions ~~(“RSUs”),~~ and PSUs. The PSUs granted in ~~2020~~2021 were tied to ~~both~~ goals related to ~~return on average net tangible assets (“ROANTA”) and on relative~~absolute TSR performance ~~against companies in the Russell 2000 Index. One-half of the PSUs granted were based on goals related to TSR~~ over a ~~three- year performance period and one-half of the PSUs granted were based on goals related to ROANTA over the~~ 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:

By providing a substantial portion of our named executive officers’ total compensation package in the form of ~~equity- based~~equity-based awards, we have emphasized variable pay over fixed pay, strengthening the alignment between our named executive officers and our ~~shareholders~~stockholders by creating an incentive to build ~~shareholder~~stockholder value over the long-term.

Our PSUs are earned based on the achievement of performance goals designed to directly focus our named executive officers on the achievement of share value creation.

Our annual performance-based bonus is contingent upon the achievement of financial performance and qualitative goals. The amount of bonus compensation ultimately received varies with our annual financial performance, thereby providing an additional incentive to maximize ~~shareholder~~stockholder 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

Our executive compensation program is determined and approved by the Compensation Committee. During ~~2020,~~2021, 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 ~~Chairman, President and~~ Chief Executive Officer in setting compensation levels for our named executive officers other than himself. The Compensation Committee solely determined the compensation of our ~~Chairman, President and~~ Chief Executive Officer.

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

Compensation Consultant; Review of Relevant Compensation Data

The Compensation Committee engaged WealthPoint, LLC (“WealthPoint”) as the independent advisor to the Compensation Committee in ~~2020.~~2021. WealthPoint reviewed the Company’s overall executive compensation program ~~in comparison~~relative to comparably-sized public companies in industries similar to the Company’s. In addition, WealthPoint advised the Compensation Committee on the appropriate mix of compensation components for compensating our executive officers and advised the Compensation Committee on matters relating to of our executive officers’ performance-based ~~compensation,~~

WealthPoint did not provide any other services to the Company or our management or have any other direct or indirect business relationships with the Company or our management. The Compensation Committee has assessed the independence of WealthPoint and concluded that its work for the Compensation Committee in ~~2020~~2021 did not raise any conflicts of ~~interest.~~interest related to the Company.

Compensation Peer Group Data and Pay Mix

The Compensation Committee has identified a peer group of companies to be used for purposes of assessing market levels of compensation. ~~For~~At the end of 2020, with the assistance of WealthPoint, the Compensation Committee reviewed the compensation peer group used to consider ~~2019~~2021 compensation to determine its continued appropriateness. Three members of the 2019 peer group, Innophos Holdings, Inc., Minerals Technologies, Inc., and A. Schulman, Inc. had been acquired, and were no longer available to be used as peers. Three companies were added to the peer group, including Balchem Corporation, Ferro Corporation and Ingevity Corporation.

The companies below were selected as the peer group because they are in the chemical and specialty chemical space and generally have revenues ranging from approximately 50% to 200% of the Company’s revenues.

Albermarle Corporation	GCP Applied Technologies, Inc.	Quaker Chemical Corporation
Avient Corporation	H.B. Fuller Company	Sensient Technologies Corporation
Balchem Corporation	Ingevity Corporation	Stepan Company
Cabot Corporation	Innospec, Inc.	W.R. Grace & Co.
Element Solutions, Inc.	International Flavors & Fragrances, ~~Inc~~Inc.	Westlake Chemical Corporation
Ferro Corporation	Kraton Corporation
FMC Corporation	Minerals Technologies, Inc.

In 2020, the Compensation Committee reviewed competitive compensation practices, including peer group compensation data and a variety of other factors, to confirm that the structure of our cash compensation and equity-based awards was consistent with our compensation philosophy and market practice. As a result of that review, ~~in 2020,~~for 2021, the Compensation Committee determined to structure the ~~long term~~long-term incentive grant to include ~~both a financial and~~ TSR vesting ~~component~~ for the PSUs, as well as the mix of PSUs and RSUs. In addition, the Compensation Committee used the peer group data provided by WealthPoint in order to determine the appropriate mix between cash compensation and equity-based awards.

As a result of the August 2, 2021 divestiture of Performance Chemicals, the Company’s revenue size has changed and the Compensation Committee has chosen a new peer group for fiscal 2022.

2022 PROXY STATEMENT

TABLE OF CONTENTS

Elements of Compensation in ~~2020~~2021

For ~~2020,~~2021, our compensation program for the named executive officers consisted of, in whole or part:

Base salary;

Annual performance-based cash awards;

Long-term equity incentive awards; and

Other benefits (retirement, health, perquisites, etc.).

In addition, in 2021, the Company completed its two-year strategic review and restructuring. This included the sale of its Performance Chemicals business and the rebranding of the Company as Ecovyst. It also included the addition of three new executives to the named executive officer ranks. In connection with these accomplishments the Compensation Committee determined to make a special grant of RSUs to the named executive officers, and these are described more particularly below.

Base Salary

We provide an annual base salary to our named executive officers to induce talented executives to join or remain with our ~~Company,~~company, to compensate them for their services during the year and to provide them with a stable source of income.

The base salary levels of our named executive officers are reviewed annually by the Compensation Committee to determine whether an adjustment is warranted. The Compensation Committee may take into account numerous factors in making its base salary determinations, none of which are dispositive or individually weighted, including our financial performance, the state of our industry and the local economies in which we operate, the named executive officer’s relative importance and

responsibilities, the named executive officer’s performance and periodic reference to comparable salaries paid to other executives of similar experience in our industry in general, based on the Compensation Committee’s expertise as well as market data drawn from our peer group, referenced above.

In December ~~2019~~2020 and in April 2021, the Compensation Committee determined to make certain changes to the base salaries of ~~certain~~two of our currently employed named executive ~~officers~~officers. Mr. Bitting’s base pay was increased effective ~~beginning in 2020.~~January 1, 2021, and Mr. Feehan’s base salary was increased effective August 1, 2021. In addition, Messrs. Bitting, Feehan and Schneberger were awarded base salary increases effective January 1, 2022. The ~~decision~~decisions to ~~do so was~~make these changes were based on current market data, ~~performance of the incumbents,~~ and the ~~fact that base salary had not been adjusted for~~promotion of three executives into the ranks of the named executive ~~officers since 2017 (and for Messrs.

Annual Performance-Based Cash Awards – The ~~PQIP~~EIP

We provide our named executive officers with annual performance-based cash award opportunities linked to our annual financial and operational performance. For ~~2020,~~2021, the Compensation Committee chose three performance metrics, the achievement of which would determine the amount of annual cash awards paid to our named executive officers. The performance metrics, along with the reasons the Compensation Committee chose each of them for purposes of the ~~PQIP,~~EIP, are outlined below.

	Factor			Weight
	Adjusted EBITDA			60%
	Adjusted Free Cash Flow			20%
	Safety			20%

In order for the Adjusted Free Cash Flow and Safety goals to be paid out, a minimum of $193.6 million Adjusted EBITDA was required to be achieved.

	Metric/Goal			Reason for ~~inclusion~~Inclusion in the ~~PQIP~~EIP
	Adjusted EBITDA			Adjusted EBITDA is the most significant indicator of operating performance. Improvements in operating performance are directly linked to sustainable share value creation.
	Adjusted Free Cash Flow			Adjusted ~~free cash flow~~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~~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.
	Safety			There is a direct link between an improving safety record, higher worker productivity and sustained share value creation.

~~2021 PROXY STATEMENT~~

~~TABLE OF CONTENTS~~

	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, ~~nonrecurring~~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~~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.
	Safety			Recordable rate of safety incidents, which is a standardized measure of OSHA-recordable injury or illness. ~~For 2020~~In 2021 a second measure has been utilized, number of ~~“Perfect~~“HSE Perfect Days”, which is the number of days without a significant safety or environmental incident. The recordable rate metric is weighted 10 percent and the HSE Perfect Days metric is weighted 10 percent.

Adjusted EBITDA and Adjusted Free Cash Flow are non-GAAP financial metrics. An explanation of how we calculate these metrics is contained in our Annual Report on Form 10-K for the fiscal year ended December 31, ~~2020~~2021 filed with the Securities and Exchange Commission.

2022 PROXY STATEMENT

TABLE OF CONTENTS

The target annual performance-based cash award opportunity for each eligible executive was set as a percentage of base salary (i.e., actual base salary paid during ~~2020)~~2021). ~~The target award percentages for each of our named executive officers remained the same for 2020 as in 2019.~~ For ~~2020,~~2021, the target award percentages were as follows:

	Executive			FYE Target Award as % of Base Pay
	Belgacem Chariag			100%

For ~~2020,~~2021 the ~~PQIP~~EIP target and maximum goals for the Adjusted EBITDA metric and the Adjusted Free Cash Flow metric were set by the Compensation Committee in January 2021. On August 2, 2021, the Performance Chemicals business was sold to a partnership between Cerberus Capital Management L.P. and Koch Minerals & Trading, LLC. The Performance Chemicals business contributed a substantial amount of Adjusted EBITDA and Adjusted Free Cash Flow to the Company, and the Adjusted EBITDA and Adjusted Free Cash Flow performance goals were set assuming that the Performance Chemicals business would be part of the Company’s financial results for the entire year. As a result, the Compensation Committee determined to adjust the Adjusted EBITDA and Adjusted Free Cash Flow targets after the disposition to take into account the fact that the Performance Chemicals business would no longer be contributing to the Company’s financial results.

The numbers in the tables below reflect the EIP Adjusted EBITDA and Adjusted Free Cash Flow target and maximum goals, as amended following the disposition of the Performance Chemicals business.

For 2021, the EIP was structured to pay for achieving goals related to ~~each of~~ the ~~four~~following performance metrics:

Category	Weight	Scale	Threshold	Target	Maximum	Category	Weight	Scale	Threshold	Target	Maximum
Adjusted EBITDA	60%	Performance as a percent of target	94.5%	100%	103%	Adjusted EBITDA	60%	Performance as a percent of target	94%	100%	104%

Long-Term Equity Based Incentive Awards

Since the time of our initial public offering, all of our equity-based awards have been granted under the 2017 ~~Omnibus Incentive Plan, as Amended and Restated (the “2017 Plan”).~~Plan. Those awards have included time vesting restricted stock units, time vesting stock options, and PSUs tied to both financial performance and TSR goals.

The ~~2020~~2021 long-term ~~equity- based~~equity-based incentive awards we granted to our named executive officers included a mix of time vesting RSUs and PSUs. The number of PSUs that were granted in 2021 and which are eligible to be earned is tied to the achievement of TSR targets ~~and ROANTA targets~~ over the three-year performance period ending December 31, ~~2022.~~2023.

Messrs. ~~Crews, Randolph~~Bitting, Feehan and ~~Kolberg~~Crews continue to hold performance vesting equity awards granted prior to our initial public offering, which were granted under the PQ Group Holdings Inc. Stock Incentive Plan (“SIP”). The performance-based stock options and performance-based restricted shares currently outstanding are all unvested and will vest only on the achievement with respect to shares of our Common Stock of an average closing trading price equal or exceeding, in any ten trading day period, the lowest amount which, when multiplied by the number of shares of our 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. The quotient described above is referred to in this Compensation Discussion and Analysis as the “MOI Target.” As of December 31, ~~2020,~~2021, none of the performance-based stock options and performance-based restricted shares granted prior to our initial public offering had vested based on achievement of the MOI Target.

~~At the 2020 Annual Meeting, we asked shareholders to approve an Amendment~~Sale of business units, dividend equivalents, and ~~Restatement of the 2017 Plan, as well as replenishment of our equity pool. More than 98 percent of shares were voted in approval of the amendment and restatement and share replenishment.~~

Depending on progress against performance goals, an amount ranging from 0% to 200% of target PSUs granted may actually be earned. The PSUs actually earned will be determinedoutstanding on the date the ~~Compensation Committee certifies~~dividend was declared. In particular, the ~~level~~Board of ~~achievement~~Directors authorized the payment of dividend equivalents on unvested RSUs, PSUs and performance-based restricted shares outstanding as of the ~~various performance measures, which will occur subsequent to the end~~date of the ~~three-year performance period but before~~dividend payment, with the actual payments to be made as those unvested RSUs, PSUs, and performance-based restricted shares vested. In addition, the Board of Directors authorized a lowering of the per share strike price on all stock options outstanding as of that date by the special dividend amount of $1.80.

On August 2, 2021, the Company ~~files~~completed the sale of its Performance Chemicals business and declared a $3.20 per share dividend payable August 23, 2021 to stockholders of record August 12, 2021.

In addition, any unvested PSUs will be eligible to vest during the 1-year period following Mr. Randolph’s termination. More information regarding vesting conditions of Mr. Randolph’s grants is contained in the discussion of Severance, below.

~~The 2020 PSU grant is broken into two equally weighted parts.~~

The first part is based on performance related to average ROANTA over the three- year performance period. A threshold level of PSUs is earned (25 percent of target) for achieving average ROANTA at 90 basis points below target. 100 percent of target PSUs are earned for achieving average ROANTA at target. The maximum level of PSUs is earned (200 percent of target) for achieving ROANTA performance 20 basis points or more than target average three- year ROANTA.

The second part is based on performance related to PQ’s three- year average TSR relative to the TSR of companies which comprise Russell 2000 index of mid-cap companies. A threshold level of PSUs is earned (25 percent of target) for achieving TSR at the 25th percentile of the companies in the Index. 100 percent of target PSUs are earned for achieving TSR at the median TSR of the companies in the Index. The maximum level of PSUs is earned (200 percent of target) for achieving TSR at the 75th percentile of the companies in the Index.

Grants in 2021

In December of 2020, the Compensation Committee determined that it was advisable to make another grant of long-term equity incentive awards to its named executive officers, and did so on January 18, 2021. The equity incentive awards were in the form of RSUs and PSUs.

In ~~2020~~ the ~~Company undertook a strategic assessment~~course of ~~its business, with a view toward a possible restructuring.

The Compensation Committee ~~determined to make~~authorized three separate equity incentive awards in 2021.

First, the Compensation Committee authorized a special grant of time-vested RSUs to certain named executive officers for their work in the 2020 strategic assessment and restructuring, including the successful sale of ~~its~~the Performance Materials segment. This grant ~~vests~~vested over a one-year period, generally subject to continued service. Messrs. Chariag, Crews, Schneberger and Koscinski participated in this grant.

Second, the Compensation Committee authorized aan annual grant of ~~time- vested~~time-vested RSUs which vest over a ~~three- year~~three-year period. One third of the RSU awards will vest on each of January 5, 2022, ~~January 5,~~ 2023 and ~~January 5,~~ 2024, respectively, generally subject to continued service.

Third, the Compensation Committee authorized aan annual grant of PSUs to each of the named executive officers, which PSUs will be earned, if at all, at the end of the ~~three year~~three-year performance period ended December 31, 2023. ~~One hundred percent of target~~ PSUs will be earned depending on achievement of benchmark goal improvement in the Company’s TSR over the ~~three- year~~three-year performance period. Depending on progress against performance goals, an amount ranging from 0% to 200% of target PSUs granted may actually be earned. The PSUs actually earned will be determined on the date the Compensation Committee certifies the level of achievement of the various performance measures, but no later than 60 days after the end of the three-year performance period. In order to be eligible to earn all awarded PSUs, ~~a participant~~the named executive officer generally must continue to provide services until the end of the performance period.

The grants made to our named executive officers on January 18, 2021 were as follows:

2019 PSU Grant

The 2019 PSU grant contained two financial performance metrics: the average annual return on average net tangible assets (“ROANTA”) over the three-year performance period and the average annual Adjusted Free Cash Flow over the three-year performance period. The performance period ran from January 1, 2019 to December 31, 2021. The original performance metrics are reproduced in the table below.

Original PSU Grant Formula
Average Annual ROANTA		Performance Factor
Average Annual ROANTA		Threshold		Target		Maximum
Maximum	18.50%	100%	125%	150%	175%	200%
	18.25%	75%	100%	125%	150%	175%
Target	18.00%	50%	75%	100%	125%	150%
	17.50%	25%	50%	75%	100%	125%
Threshold	17.00%	13%	25%	50%	75%	100%

Average Annual Adjusted Free Cash Flow ($ in Thousands)		117,000	127,000	138,000	145,000	150,000
Average Annual Adjusted Free Cash Flow ($ in Thousands)		Threshold		Target		Maximum

The ROANTA and Adjusted Free Cash Flow targets were set in January 2019 and assumed that the Performance Materials business and the Performance Chemicals business would be part of the Company for the entire performance period.

In October 2021, the Compensation Committee decided that the performance goals relating to the 2019 PSUs should be adjusted to take into account the fact that the Performance Materials business and the Performance Chemicals business were divested during the performance period. In the course of making the adjustments, it was determined that the Adjusted Free Cash Flow performance would result in a payment approaching 200 percent of target, but ROANTA performance would fall below threshold. The way the original performance metrics were structured, if performance on either factor fell below threshold, no PSUs would be earned.

The Compensation Committee determined that the Company’s strong Adjusted Free Cash Flow performance contributed to the Company’s long-term share value, and that it would be an unfair result if zero PSUs would be earned for the performance measurement period. Accordingly, the Compensation Committee decoupled the two performance metrics and assigned a 50 percent weight to each one. The revised 2019 PSU grant vesting formula is reproduced below:

Revised 2019 PSU Grant Vesting Formula
50% of Target PSUs shall be earned as follows:				50% of Target PSUs shall be earned as follows:
	Threshold	Target	Maximum		Threshold	Target	Maximum
Average Annual ROANTA	17%	18%	18.50%	Average Annual Free Cash Flow ($ in Thousands)	96,000	112,000	123,000
PSUs Earned as a % of Target	12.50%	100%	200%	PSUs Earned as a % of Target	12.50%	100%	200%

Under the revised formula, the average annual ROANTA was below the 17 percent threshold and no PSUs were earned based on the ROANTA portion of the vesting formula.

The average annual Adjusted Free Cash Flow was $137.3 million and PSUs were earned at 200 percent based on the Adjusted Free Cash Flow portion of the vesting formula.

Grants Made in 2022

The Compensation Committee decided to make long-term equity-based incentive awards in 2022, and those awards were granted on January 17, 2022. With the sale of the Performance Materials business and the Performance Chemicals business, the Company has a new focus, as well as three new named executive officers. In recognition of that, the Compensation Committee decided to make three types of grants. First, our named executive officers received a grant of PSUs which could be earned based on achievement of TSR goals over a three-year period. Second, we made a grant of time-vesting RSUs, which vest ratably on January 5, 2023, January 5, 2024, and January 5, 2025. Third, we made a special retention grant of time vesting RSUs, which cliff vest on July 1, 2023. The awards granted were as follows:

Transition and General Release Agreement with Mr. ~~Randolph~~Crews

On ~~December 16, 2020,~~March 22, 2021 we entered into a transition and general release agreement with Mr. ~~Randolph~~Crews in connection with his termination of employment with the Company effective ~~December 14, 2020.~~September 30, 2021.

Stock Ownership Guidelines for Executive Officers

Under our stock ownership guidelines, applicable to our executive officers and our non-employee directors, each of our named executive officers, other than our Chief Executive Officer, is expected to have ownership of our Common Stock in an amount equal to at least three times the named executive officer’s annualized base salary, and our Chief Executive Officer is expected to have ownership of our Common Stock in an amount equal to at least five times his annualized base salary.

Executive officers subject to the guidelines have five years to achieve the required ownership levels and, until they satisfy their ownership requirements, are subject to a holding requirement with respect to 50% of the shares of Common Stock they acquire upon the vesting or exercise of their equity-based awards (on an after-tax basis).

The following table summarizes the ownership of our Common Stock as of December 31, ~~2020~~2021 by our named executive officers:

TABLE OF CONTENTS

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. 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.

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) for a transition period following the initial public offering (the “Post-IPO Transition Period”). The Amendment and Restatement of the 2017 Plan which ~~shareholders~~stockholders approved at the 2020 annual meeting ended the Post-IPO Transition Period with respect to the 2017 Plan. The Compensation Committee believes that its primary responsibility is to provide a compensation program in accordance with its overall compensation philosophy and policies described above, and it retains flexibility to approve or amend compensation arrangements that may result in a loss of deductibility or may not be deductible in whole or in part under Section 162(m).

Retirement Plan Benefits

We maintain the ~~PQ Corporation~~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 Corporation~~Ecovyst Non-Qualified Personal Retirement Account Excess Savings Plan, an excess benefit plan designed to provide

2022 PROXY STATEMENT

TABLE OF CONTENTS

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 Corporation~~Ecovyst 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 our 401(k) plan due to Internal Revenue Code limits. The plan is administered by a committee appointed by our Board.

Contributions — There 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 losses — — Participant 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 distributions — — Participants 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 lump sum on the first to occur of the participant’s separation from service or disability, provided

~~2021 PROXY STATEMENT~~

that distributions to “key employees” within the meaning of Section 416(i) of the Internal Revenue Code as of the date of the participant’s separation from service will not be made until six (6) months after the participant’s separation from service or, if earlier, the participant’s death.

The following table provides information regarding participation by our named executive officers in the PRA SERP during the year ended December 31, ~~2020.~~2021.

Potential Payments Upon Termination or Change in Control

Cash Severance

~~Each of our named executive officers is~~Messrs. Chariag and Koscinski are party to a severance agreement or letter agreement with us that provides them with severance protections and benefits in the event of certain qualifying terminations of their employment.

~~In addition,~~ They are also covered by the Company’s Amended and Restated Severance Plan (the “Severance Policy”) which was adopted by the Company effective January 1, 2020. ~~Eligible employees,~~

Messrs. Schneberger, Bitting and Feehan are not party to a severance agreement or letter agreement with us and are covered by the Severance Policy.

Employees, including our named executive officers, who have entered into a written individual employment agreement or severance agreement, or offer letter with the Company containing a severance provision prior to January 1, 2020 will only receive the severance benefit that provides the maximum benefit, either from such prior agreement or from the Severance Policy, but not both.

The severance agreements for Messrs. Chariag ~~Crews,~~ and Koscinski provide for the severance payments and benefits described below in connection with specified termination events, subject to the named executive officer’s execution and non-revocation of a release of claims and continued compliance with the restrictive covenants described below. The terms “cause”, “good reason” and “disability” are each defined in the applicable agreements.

Under the terms of their severance agreements, in the event of a termination of the named executive officer’s employment by the Company without cause or by the named executive officer with good reason, each of Messrs. Chariag ~~Crews,~~ and Koscinski will receive: (i) his base salary and target annual incentive bonus for a two-year period following termination paid in equal installments over such two-year period in accordance with the normal payroll practices of the Company; (ii) a pro rata amount of the annual incentive bonus that would have been payable in the year of termination based on the number of days the named executive officer was employed during the calendar year and subject to the Company’s achievement of applicable performance goals, which amount will be paid in a lump sum at the time annual bonuses under the ~~PQIP~~EIP are normally paid; and (iii) continuation of health benefits at active employee rates for 24 months (or until the named executive officer otherwise becomes eligible for health benefits as a result of commencing new employment) to the extent permitted by the applicable benefit plan, or reimbursement of the costs for such coverage under COBRA.

~~Messrs. Kolberg and Beninati received offer letters with severance provisions, but in each case they would enjoy a greater benefit under the Severance Policy.~~ Under the terms of the Severance ~~Policy each executive is~~Plan, Messrs.

notice of termination, in addition to the severance payments. The severance payments consist of 52 weeks of severance pay, plus two weeks for each ~~additional~~completed year of service with credit for a partial year, up to a maximum of 78 weeks. In addition, the severance payments include an amount equal to each executive’s target bonus for each year of severance paid, plus a pro rata target bonus for each fractional year of severance paid. These amounts will be paid in equal installments over the severance period. Finally, each executive will be eligible to receive a pro rata amount of any annual incentive bonus that would have been payable in the year of termination based on actual achievement of the applicable performance goals, which amount will be paid in a lump sum at the time annual bonuses are normally paid, provided the effective date of termination was on or after July 1 in the year of termination; as well as continuation of health benefits at active employee rates over the severance period (or until the executive otherwise has access to substantially equivalent health benefits as a result of commencing new employment).

If Mr. Chariag’s employment is terminated by the Company without cause or by him with good reason, in each case, within the one year following a change in control of the Company, in addition to the severance payments and benefits described above, he will also be entitled to a payment equal to the sum of his base salary and target annual incentive bonus paid in a lump sum on the second anniversary of the date his employment terminates.

If the employment of Messrs. Chariag ~~Crews,~~ or Koscinski is terminated due to death or disability, the individual (or his estate) will receive a pro rata amount of his target annual incentive bonus.

Each of the severance agreements provides that in the event that all or any portion of the payments or benefits provided under the severance agreement would constitute an “excess parachute payment” within the meaning of Section 280G of the Internal Revenue Code, the named executive officer will be entitled to receive an amount equal to the greater of (on an after-tax basis) (i) the amount of such payments or benefits reduced so that no portion of the payments and benefits would fail to be deductible under Section 280G, or

(ii) the amount otherwise payable reduced by all taxes, including the excise tax imposed under Section 4999 of the Internal Revenue Code.

The severance agreements with each of Messrs. Chariag ~~Crews~~ and Koscinski contain restrictive covenants for the benefit of the Company, including two-year post termination non-compete and non-solicitation covenants, a prohibition of disclosure of confidential information, ~~and~~ an assignment of inventions and patents to the ~~Company. The severance benefits provision of Mr. Kolberg’s offer letter contain the same restrictive~~Company and perpetual confidentiality and non-disparagement covenants. The Severance Policy, which governs payments to ~~Mr. Beninati~~Messrs. Schneberger, Bitting and Feehan contains the same restrictive covenants.

Prior to his termination of employment, the severance agreement with Mr. Randolph provided for similar severance payments and benefits as described above in connection with specified termination events. As discussed above, Mr. Randolph had a termination of employment with the Company in 2020. The terms of Mr. ~~Randolph’s~~Crews’ separation agreement, along with the forms and amounts of actual severance paid, are discussed above in the section entitled “Transition and General Release Agreement with Mr. ~~Randolph.~~Crews.”

Amended and Restated Severance Plan of ~~PQ Corporation~~Ecovyst Catalyst Technologies LLC

The Severance ~~Policy~~Plan was adopted by the Company effective January 1, 2020. There are no changes to our named executive officers’ severance benefits due to the adoption of the Severance Policy, except for Mr. Beninati, as described above. However, going forward the Severance Policy may2020, and will likely impact severance benefits toof our future named executive officers.

Equity Awards

The non-vested portion of equity awards subject to time vesting will forfeit upon a change of control of the Company unless the successor determines to maintain the awards for executives whose employment continues.

Equity awards subject to performance vesting based on the MOI Target will vest and, as applicable, become exercisable upon a change of control only if such change of control results in the MOI Target being satisfied. A portion of the PSUs granted in ~~2019~~2020, 2021 and ~~2020~~2022 may be deemed earned and may vest upon a change of control, with such portion to be determined by the Compensation Committee based on the level of achievement of the applicable performance measures prior to the change of control.

~~2021 PROXY STATEMENT~~

~~TABLE OF CONTENTS~~

Upon a termination of the named executive officer’s employment due to death, disability, retirement, without cause, or for good reason (if applicable), equity awards subject to performance vesting based on the MOI Target will vest, and as applicable, become exercisable, only if the MOI Target is satisfied on or before the six month anniversary of the termination of employment.

Upon a termination of the named executive officer’s employment due to disability, retirement, without cause, or for good reason (if applicable), a pro rata portion of the target number of PSUs granted in 2019, 2020, 2021 and ~~2020~~2022 will remain outstanding until the applicable vesting date of the award and will be eligible to be earned based on actual performance, with such pro rata portion based on the number of days of the performance period that occurred prior to the termination of employment. Upon a termination of the named executive officer’s employment due to death, a pro rata portion of the target number of PSUs granted in ~~2019~~2020, 2021 and ~~2020~~2022 will be deemed earned at target levels and will vest, with such pro rata portion based on the number of days of the performance period that occurred prior to the named executive officer’s death.

With respect to ~~time based~~time-based restricted stock units granted in the period from ~~2018-2020,~~2019-2022, and outstanding ~~time based~~time-based stock options, there would be no acceleration of vesting on a termination of employment prior to the applicable vesting date of the award.

TABLE OF CONTENTS

The table below shows the estimated value of the severance benefits that each of our currently employed named executive officers would have been entitled to receive if his employment was terminated by us without cause or by the named executive officer for good reason or the termination was due to death, disability, or retirement. The table below assumes that such termination occurred on December 31, ~~2020.~~2021. The table below also shows the estimated value associated with the acceleration of certain outstanding equity awards upon a change of control of the Company, assuming that such change of control occurred on December 31, ~~2020.~~2021. The actual amounts that would be paid to any named executive officer can only be determined at the time an actual termination of employment or change of control occurs and could vary from those listed below.

CEO Pay Ratio

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 ~~2020,~~2021, except for our Chief Executive Officer, was ~~$74,774.~~$117,502. The total annualized compensation for our Chief Executive Officer for ~~2020~~2021 was ~~$5,580,953.~~$8,953,055. The

~~2021 PROXY STATEMENT~~

~~TABLE OF CONTENTS~~

resulting ~~2020~~2021 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 ~~74.6:~~76.19:1.

We chose a measurement date of December 31, ~~2020~~2021 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, ~~2020.~~2021. 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, ~~2020,~~2021, but was not employed by the Company for all of ~~2020,~~2021, 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 ~~2020~~2021 Summary Compensation Table in this ~~proxy statement.~~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. 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, 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 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.

We operate in accordance with a written charter adopted by the Board and reviewed annually by the Committee. We are responsible for overseeing the quality and integrity of ~~PQ’s~~the Company’s accounting, auditing and financial reporting practices. In accordance with the rules of the Securities and Exchange Commission and the New York Stock Exchange, the Audit Committee is composed entirely of members who are independent, as defined by the listing standards of the New York Stock Exchange and ~~PQ’s~~the Company’s Corporate Governance Guidelines. Further, the Board has determined that one of our members (Ms. Ward) is an audit committee financial expert as defined by the rules of the Securities and Exchange Commission.

We believe that we fully discharged our oversight responsibilities as described in our charter, including with respect to the audit process. We have discussed with PwC the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the Securities and Exchange Commission and have received the written disclosures and the letter from PwC required by applicable requirements of the PCAOB regarding PwC’s communications with the Audit Committee concerning independence, and discussed with PwC its independence. We discussed with management, the internal auditors and PwC ~~PQ’s~~the Company’s internal control over financial reporting and the internal audit function’s organization, responsibilities, budget and staffing. We reviewed with both PwC and our internal auditors their audit plans, audit scope, identification of audit risks and their audit efforts.

We discussed and reviewed with PwC their communications required by the Standards of the PCAOB and, with and without management present, discussed and reviewed the results of PwC’s examination of ~~PQ’s~~the Company’s financial statements. We also discussed the results of the internal audit examinations with and without management present.

We reviewed the audited consolidated financial statements of PQthe Company as of and for the fiscal year ended December 31, ~~2020~~2021 with ~~Management~~management and PwC. Management has the responsibility for the preparation of ~~PQ’s~~the Company’s financial statements, and PwC has the responsibility for the audit of those statements.

Based on these reviews and discussions with management and PwC, we approved the inclusion of ~~PQ’s~~the Company’s audited financial statements in its Annual Report on Form 10-K for the year ended December 31, ~~2020~~2021 for filing with the Securities and Exchange Commission. We also have selected PwC as the independent registered public accounting firm for the year ended December 31, ~~2021,~~2022, subject to ratification by ~~PQ’s~~the Company’s stockholders.

Audit fees were for professional services rendered for the audit of our annual audited consolidated financial statements and review of our quarterly financial statements, advice on accounting matters directly related to the audit and audit services, and assistance with review of documents filed with the Securities and Exchange Commission.

Audit related fees were for audits and reviews not required under securities laws, as well as accounting consultations, ~~compilations~~ and other assurance-related ~~services.~~services such as statutory interim reviews and carve-out audits.

Tax fees were for professional services related to tax compliance and tax consulting services, including assistance with tax audits.

All other fees were for technical research software license ~~fees.~~fees and non-audit services.

The Audit Committee pre-approves all audit services and all permitted non-audit services, including engagement fees and terms, to be provided by the independent auditors. Our policies prohibit PQEcovyst from engaging PwC to provide any non-audit services prohibited by applicable Securities and Exchange Commission rules. In addition, we evaluate whether ~~PQ’s~~Ecovyst’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 3

RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Householding of Proxy Materials

Like many other companies, brokers, banks, and nominee record holders, PQEcovyst participates in a practice commonly known as “householding,” where a single copy of our Proxy Statement and ~~2020~~2021 Annual Report is sent to one address for the benefit of two or more stockholders sharing that address unless we have received contrary instructions. Householding is permitted under rules adopted by the Securities and Exchange Commission as a means of satisfying the delivery requirements for proxy statements and annual reports, potentially resulting in extra convenience for stockholders and cost savings for companies. If you hold your shares through a broker, you may have consented to reducing the number of copies of materials delivered to your address.
