PROXY STATEMENT

For the Annual Meeting of Stockholders of

STEPAN COMPANY

1101 Skokie Boulevard

Northbrook, Illinois 60062

To be held at 9:00 a.m. (CDT) on April 30, 2024

INFORMATION CONCERNING SOLICITATION AND VOTING

The enclosed proxy is solicited by the Board of Directors, and the Company will bear the entire expense of solicitation. Such solicitation is being made by mail, and the Company’s officers and employees may solicit proxies from stockholders personally or by telephone, mail or other means. The Company will make arrangements with the brokers, custodians, nominees and other fiduciaries who request the forwarding of solicitation material to the beneficial owners of shares of the Company’s stock held of record by such brokers, custodians, nominees and other fiduciaries, and the Company will reimburse them for their reasonable out-of-pocket expenses. This proxy statement and proxy are first being distributed to stockholders commencing on or about March 26, 2024.

At the close of business on March 4, 2024, the record date for the meeting, there were 22,464,074 shares of the Company’s Common Stock (“Common Stock”) outstanding, each share of which is entitled to one vote on each matter to be voted on at the meeting. The required quorum at the Annual Meeting is a majority of the outstanding shares of the Company’s Common Stock as of the record date.

If you submit your proxy but abstain from voting on one or more matters, your shares will be counted as present at the meeting for the purposes of determining a quorum. You may revoke your proxy by attending the meeting and voting in person or by delivering to the Secretary of the Company a revocation of the proxy or an executed new proxy bearing a later date.

You may vote “FOR,” “AGAINST” or “ABSTAIN” on each of the nominees for the Board of Directors. You may vote “FOR,” “AGAINST” or “ABSTAIN” on each of the other proposals. If you vote to “ABSTAIN” with respect to a nominee for the Board of Directors, your abstention will not be included in the vote totals and will not affect the outcome of the vote. If you vote to “ABSTAIN” with respect to any other proposal, your abstention will have the effect of a vote against the proposal.

For any other business that may properly come before the meeting, votes will be cast pursuant to the authority granted by the enclosed proxy in accordance with the best judgment of the individuals acting under the proxy. The Board of Directors is not currently aware of any other business that may come before the meeting.

If you hold your shares in street name and do not provide voting instructions to your broker, custodian, nominee or other fiduciary, your shares will not be voted on any non-routine matters and will be considered “broker non-votes.” Non-routine matters include the election of directors and the Say-on-Pay vote. Your broker may vote your shares without instruction on the ratification of the appointment of the Company’s independent registered public accounting firm. Broker non-votes will be counted as present at the meeting for the purpose of determining a quorum but will not be included in the vote totals for non-routine matters and will not affect the outcome of those votes. Please instruct your broker or bank so your vote can be counted on all proposals.

1

In order to ensure the necessary quorum at the Annual Meeting, please mark, sign and return the enclosed proxy promptly in the envelope provided. You may also vote via the internet by visiting http://www.envisionreports.com/SCL or by phone by calling (800) 652-8683. Internet and phone voting will be available 24 hours a day, seven days a week until 1:00 a.m. (EDT) on April 30, 2024. If voting via the internet or by phone, please have your proxy card available and follow the instructions to vote. Even if you vote prior to the meeting, you are invited to attend the meeting.

In the future, in accordance with the rules of the Securities and Exchange Commission (the “SEC”), the Company may furnish proxy materials, including its proxy statements and annual reports, to stockholders by providing access to these documents on the internet instead of mailing printed copies. If the Company elects to take this approach, most stockholders would not receive printed copies of the proxy materials. Instead, the notice would provide instructions on how to access and review the proxy materials on the internet. The notice would also provide instructions on how to submit your proxy via the internet. For stockholders who prefer to receive printed copies of the proxy materials, the notice would provide instructions for requesting printed copies.

PROPOSAL NO. 1: ELECTION OF DIRECTORS

Stockholders and the persons named in the enclosed proxy will vote, pursuant to the authority granted by the stockholder in the enclosed proxy, on the election of Mr. Randall S. Dearth, Ms. Susan M. Lewis and Ms. Jan Stern Reed as directors of the Company, to hold office until the Annual Meeting of Stockholders to be held in 2027. The Board of Directors is divided into three classes serving staggered three-year terms. Directors for each class are elected at the annual meeting of stockholders in the year in which the term for their class expires. Mr. Dearth, Ms. Lewis and Ms. Reed are current directors whose terms expire in 2024. Mr. Dearth and Ms. Reed were last elected by the Company’s stockholders at the 2021 Annual Meeting. Ms. Lewis was elected by the Board of Directors on February 15, 2024. The nominations of Mr. Dearth, Ms. Lewis and Ms. Reed have each been reviewed and recommended by the Nominating and Corporate Governance Committee and the Board of Directors.

It is with great sadness that the Board of Directors and the Company acknowledge the death of Gregory E. Lawton on August 18, 2023. Mr. Lawton had been a director since 2006. The Board of Directors and the Company wish to honor the memory of Mr. Lawton and the valuable leadership and guidance he provided.

In the event any of Mr. Dearth, Ms. Lewis and Ms. Reed is unable to serve as director, votes will be cast, pursuant to the authority granted in the proxy, for such person or persons as may be designated by the Board of Directors. The Board of Directors at this time is not aware of any nominee who is or will be unable to serve as director, if elected.

Under the Company’s Amended and Restated By-laws, in an uncontested election directors are elected by a majority of the votes cast by stockholders. An uncontested election of directors means an election for which the number of nominees does not exceed the number of directors to be elected at the specific election. Because three directors are to be elected, and Mr. Dearth, Ms. Lewis and Ms. Reed are the sole nominees, this election is uncontested, and therefore the nominees must receive a majority of votes cast by stockholders to be elected.

Based solely upon a review of such reports filed with the SEC and written representations from certain reporting persons, the Company believes that all such required reports have been timely filed, other than a report by Mr. F. Quinn Stepan, Jr. reporting shares acquired by Mr. Stepan’s father pursuant to a distribution of deferred shares on February 2, 2023, which form was inadvertently filed late due to administrative error.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Policies and Procedures for Approving Related Person Transactions

The Company has adopted a written policy entitled “Related Party Transaction Policy” (the “Related Party Transaction Policy”). The policy was initially approved by the Audit Committee of the Board of Directors in February 2007, has been annually reviewed by the Audit Committee and was last amended in April 2021. This policy applies to material transactions (“Related Party Transactions”) involving the Company and a Related Party, which is defined as a person or entity who is a Company executive officer, director, nominee for election as a director, beneficial owner of five percent or more of the Company’s Common Stock, or immediate family member of these persons, or any entity for which any of the foregoing persons is an executive officer, general partner, managing member, principal or greater than five percent beneficial owner. The Related Party Transaction Policy states that the Company will consummate a Related Party Transaction only when the Audit Committee approves the transaction after considering the factors set forth in the Related Party Transaction Policy. If advance Audit Committee approval of a Related Party Transaction is not feasible, then the Company may preliminarily enter into the transaction upon prior approval by the Chair of the Audit Committee, subject to ratification of the transaction by the Audit Committee at its next regularly scheduled meeting. No director may participate in the approval of a Related Party Transaction for which he or she is a Related Party.

The factors considered by the Audit Committee in its evaluation of a Related Party Transaction include the relevant facts and circumstances of the proposed Related Party Transaction, whether the Related Party Transaction is on terms comparable to those that could be obtained in arm’s-length dealings with an unrelated third party, the extent of the related party’s interest in the transaction and the conflicts of interest and corporate opportunity provisions of the Company’s Code of Conduct.

Transactions with Related Persons, Promoters and Certain Control Persons

Mr. Richard Stepan, brother of F. Quinn Stepan, Jr., Chairman of the Board, is a current officer of the Company. Mr. Richard Stepan is neither a director nor a nominee for director. As an employee of the Company, Mr. Richard Stepan receives a base salary, short-term and long-term incentive compensation as appropriate for his position and other regular and customary employee benefits generally available to all Company employees and is eligible for other limited perquisites available to employees at his level within the organization. For 2023, Mr. Richard Stepan was paid a salary of $329,000, and a long-term incentive compensation award of RSUs, SARs and performance shares with a target value of $450,000. Mr. Richard Stepan did not receive a short-term incentive compensation award for 2023. The Audit Committee approved the Company’s employment of Mr. Richard Stepan pursuant to the Related Party Transaction Policy and procedures described above.

Compliance Committee

The primary functions of the Compliance Committee are to assist the Board in fulfilling its oversight responsibilities with respect to (a) the Company’s overall compliance with significant legal and

12

regulatory requirements, as well as (b) compliance with its business ethics policies and Code of Conduct. The Compliance Committee held four meetings in 2023.

The Compliance Committee is comprised of Ms. Burgess, Mr. Dearth (Chair), Dr. Delgado, Ms. Lewis, Ms. Reed and Mr. Wehmer, all of whom are independent directors in accordance with the rules of the New York Stock Exchange and as described below under “Director Independence.”

Human Capital and Compensation Committee

The primary functions of the Human Capital and Compensation Committee are to (a) establish and administer the Company’s policies, programs and procedures for compensating its executive management and (b) provide advice and counsel to the Company regarding executive development and succession planning. The responsibilities of the Human Capital and Compensation Committee include reviewing and setting or recommending the compensation of the Company’s executive officers, recommending and administering cash-based and equity-based incentive compensation plans, reviewing and recommending director compensation, reviewing and recommending the Company’s Compensation Discussion and Analysis included in each proxy statement, and preparing the Human Capital and Compensation Committee Report included in each proxy statement. The Human Capital and Compensation Committee also reviews and advises management regarding the Company’s human capital management, including culture, diverse representation, inclusion and pay equity strategies, programs and initiatives. The Human Capital and Compensation Committee held three meetings in 2023.

The Human Capital and Compensation Committee is comprised of Ms. Burgess, Mr. Dearth, Dr. Delgado, Ms. Lewis, Ms. Reed (Chair) and Mr. Wehmer, all of whom are independent directors in accordance with the rules of the New York Stock Exchange and the SEC and as described below under “Director Independence.”

Nominating and Corporate Governance Committee

The primary functions of the Nominating and Corporate Governance Committee are to (a) identify individuals qualified to become board members and recommend the director nominees for election at each annual meeting of stockholders, (b) develop and recommend the Company’s Corporate Governance Guidelines, (c) oversee the evaluation of the Board of Directors and (d) recommend the members for each Board committee. In addition, the responsibilities of the Nominating and Corporate Governance Committee include making recommendations to the Board on corporate governance matters and the Board’s structure.

The Nominating and Corporate Governance Committee is comprised of Ms. Burgess, Mr. Dearth, Dr. Delgado (Chair), Ms. Lewis, Ms. Reed and Mr. Wehmer, all of whom are independent directors in accordance with the rules of the New York Stock Exchange and as described below under “Director Independence.”

Board Performance Evaluations

Annually, each director completes an evaluation of the full Board of Directors and of each standing committee on which the director serves. The Company’s Vice President, General Counsel and Secretary compiles the results of the assessments and provides the results to the Nominating and Governance Committee and to the Board of Directors. The Board of Directors initially discusses the assessment results with the Chairman and the Chief Executive Officer in attendance, and if desired by any director, the assessment results are also discussed at Executive Sessions of the non-management

13

directors and at Executive Sessions of the independent directors. This assessment evaluates the Board of Directors’ composition and contribution as a whole to the Company and reviews areas in which the Board of Directors and/or management believes a stronger contribution could be made. The Nominating and Corporate Governance Committee is also responsible for evaluating the performance of current members of the Board of Directors at the time they are considered for re-nomination to the Board of Directors.

Board Meetings and Attendance

During 2023, the Board of Directors held seven meetings. During 2023, all of the directors attended more than 75% of the total number of meetings of the Board of Directors and the meetings of committees of the Board of Directors of which each director was a member. While all directors are encouraged to attend, the Company does not have a formal policy requiring attendance at the Company’s annual meeting of stockholders. All directors attended the 2023 Annual Meeting of Stockholders in person or via remote communication. The Company currently expects that all directors and nominees will attend the 2024 Annual Meeting.

Director Nomination Process

The Corporate Governance Guidelines contain the Board of Directors membership criteria that apply to nominees recommended by the Nominating and Corporate Governance Committee for a position on the Board of Directors. Under these criteria, members of the Board of Directors should possess qualities that include strength of character, an inquiring and independent mind, practical wisdom and mature judgment. In addition to these qualities, director nominees should also possess recognized achievement, an ability to contribute to some aspect of the Company’s business, and the willingness to make the commitment of time and effort required of a director. The Nominating and Corporate Governance Committee’s process for identifying and evaluating director nominees includes recommendations by stockholders, search firms, non-management directors and executive officers, a review and background check of specific candidates, an assessment of the candidate’s independence under the director independence standards described below, and interviews of director candidates by the Nominating and Corporate Governance Committee. Ms. Lewis was first identified as a director candidate by a third-party search firm retained by the Nominating and Corporate Governance Committee.

It is the policy of the Nominating and Corporate Governance Committee to consider candidates recommended by stockholders for membership on the Board of Directors. The Nominating and Corporate Governance Committee’s evaluation of a nominee recommended by a stockholder would consider the general criteria and required information previously described in this section, and any other factors the Nominating and Corporate Governance Committee deems relevant. Any stockholder recommendation proposed for consideration by the Nominating and Corporate Governance Committee must comply with the requirements set forth in the Company’s By-laws. Among other things, a stockholder must give written notice containing the information required by the Company’s By-laws to the Secretary of the Company at Stepan Company, Secretary’s Office, 1101 Skokie Boulevard, Northbrook, Illinois 60062. The deadline to submit a director recommendation for the 2025 Annual Meeting of Stockholders is set forth in the “2025 Stockholder Proposals and Director Nominations” section below.

Board Diversity

The following charts summarize the current composition of the Board of Directors:

In accordance with the Company’s Corporate Governance Guidelines, when identifying director nominees, the Nominating and Corporate Governance Committee and the Board of Directors consider a broad definition of diversity. This definition includes, but is not limited to, diversity of professional, technical, operational, international and financial experience, skills and characteristics. In addition, the Nominating and Corporate Governance Committee and the Board will consider demographics such as age, race, ethnicity, gender and sexual orientation. The Board has also considered experience related to the Company’s business and industry. If the Nominating and Corporate Governance Committee utilizes an outside search firm to identify director nominees, it instructs the search firm to consider broadly-defined diversity in identifying potential nominees.

Director Independence

For purposes of determining director independence, the Company uses the New York Stock Exchange director independence standards. No director qualifies as “independent” unless the Board of Directors affirmatively determines that the director has no material relationship with the Company (either directly or as a partner, shareholder or officer of an organization that has a relationship with the Company). In addition, a director is not independent if:

| • |  | The director is, or has been within the last three years, an employee of the Company, or an immediate family member is, or has been within the last three years, an executive officer of the Company;

| • |  | The director has received, or has an immediate family member who has received, during any 12-month period within the last three years, more than $120,000 in direct compensation from the Company, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service);

| • |  | (A) The director is a current partner or employee of a firm that is the Company’s internal auditor or independent registered public accounting firm; (B) the director has an immediate family member who is a current partner of such a firm; (C) the director has an immediate family member who is a current employee of such a firm and personally works on the Company’s audit; or (D) the director or an immediate family member was within the last three years a partner or employee of such a firm and personally worked on the Company’s audit within that time;

| • |  | The director or an immediate family member is, or has been within the last three years, employed as an executive officer of another company where any of the Company’s present executive officers at the same time serves or served on that company’s compensation committee; or

| • |  | The director is a current employee, or an immediate family member is a current executive officer, of a company that has made payments to, or received payments from, the Company

15

| for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $1 million or 2% of such other company’s consolidated gross revenues.

Under the New York Stock Exchange rules and the Company’s Corporate Governance Guidelines, at least a majority of the Company’s directors and each member of the Audit Committee, Compliance Committee, Human Capital and Compensation Committee and Nominating and Corporate Governance Committee must meet the independence standards set forth above. The Board of Directors has determined, following the recommendation of the Nominating and Corporate Governance Committee, that each of Ms. Burgess, Mr. Dearth, Dr. Delgado, Ms. Lewis, Ms. Reed and Mr. Wehmer is independent under the standards set forth above and that Mr. Lawton, prior to his passing, was independent under the standards set forth above. In addition, the Board of Directors has determined that each of the members of the standing committees satisfies the Company’s independence standards, including the additional independence standards and financial literacy requirements required for audit committee members and compensation committee members, as applicable, established by SEC and New York Stock Exchange rules. Mr. Stepan is not deemed independent under the rules of the New York Stock Exchange because he served as an employee of the Company until April 25, 2022. Mr. Behrens is not deemed independent under the rules of the New York Stock Exchange because he currently serves as the President and Chief Executive Officer of the Company.

In making independence determinations, the Nominating and Corporate Governance Committee, with assistance from the Company’s legal counsel, evaluated responses to a questionnaire completed annually by each director regarding relationships and possible conflicts of interest between each director, the Company and management. In its review of director independence, the Nominating and Corporate Governance Committee considered the commercial, industrial, banking, consulting, legal, accounting, charitable, and familial relationships any director may have with the Company or management. In addition, the Nominating and Corporate Governance Committee considered any relationships between the Company and entities for which any director serves as management or a member of the board of directors.

Board Leadership Structure

The Board of Directors regularly reviews its leadership structure in light of the Company’s then-current needs, trends, internal assessments of Board effectiveness, and other factors. The Board does not have a policy regarding the separation of the roles of Chief Executive Officer and Chairman of the Board because the Board believes it is in the best interests of the Company to make that determination based on the position and direction of the Company and the membership of the Board.

Currently, the Board believes the interests of the Company and its stockholders are best served through a leadership model with the roles of Chairman and Chief Executive Officer separated. Mr. Stepan, who served as the Company’s Chief Executive Officer until April 25, 2022, continues to serve as Chairman of the Board. Mr. Behrens succeeded Mr. Stepan as Chief Executive Officer and is a member of the Board.

The Board believes that Mr. Stepan’s experience puts him in the best position to provide broad leadership for the Board in the role of Chairman as the Board works to deliver value to stockholders. Mr. Stepan possesses extensive knowledge and understanding of the Company and its operations, strategic planning matters, and the industry in general, developed during his over 30-year career with the Company.

To aid the Board’s independent oversight of the Company and management, the Board has elected Mr. Wehmer as Lead Independent Director. The Board believes that the election of the Lead Independent Director enhances the Board’s commitment to maintaining strong corporate governance and provides effective independent Board leadership. Among other responsibilities, the Lead Independent Director

16

presides at all Executive Sessions of the independent directors, advises the Chairman on Board meeting schedules, agendas and materials, and serves as principal liaison between the independent directors and the Chairman. The Lead Independent Director, in consultation with the Chairman and the chairs of the Human Capital and Compensation Committee and the Nominating and Corporate Governance Committee, also leads the process for the evaluation of the Chief Executive Officer.

In addition, the independent directors regularly meet in Executive Sessions without the Chairman, the Chief Executive Officer and other members of management present in accordance with the Company’s Corporate Governance Guidelines.

Risk Management

The Board of Directors takes an active role in overseeing the Company’s financial and non-financial risks. The Audit Committee, which is chaired by Ms. Burgess, leads the Board’s oversight of Company risks. The Audit Committee reviews the Company’s risk assessment and risk management policies and procedures, including those relating to the Company’s enterprise risks, financial risks and information security risks. The Audit Committee receives reports from the Company’s Director of Internal Audit, Chief Compliance and Risk Officer, Chief Financial Officer, and General Counsel, all of whom are responsible for various aspects of the Company’s risk management. The Director of Internal Audit reports directly to the Audit Committee. The Audit Committee also meets with the Company’s external auditors separately from management.

The Compliance Committee, which is chaired by Mr. Dearth, oversees risk assessment and risk mitigation related to matters within the Compliance Committee’s oversight responsibilities, which may include environmental protection, employee health, safety and security, data privacy, employment, anti-bribery and anti-corruption, product quality compliance, and ethics and compliance training.

The Human Capital and Compensation Committee, which is chaired by Ms. Reed, takes the lead role in overseeing the management of risks as they relate to the Company’s compensation policies and practices. During 2023, the Human Capital and Compensation Committee reviewed these compensation policies and practices and did not identify any risks that are reasonably likely to have a material adverse effect on the Company.

Executive Sessions

The Company’s Corporate Governance Guidelines require Executive Sessions of independent directors to be held at least once per year. Any independent director can request that additional Executive Sessions be scheduled. In 2023, seven Executive Sessions without management were held by the independent directors and chaired by Mr. Wehmer in his capacity as Lead Independent Director. In addition, Executive Sessions without management were also held after many Board committee meetings during 2023 and were chaired by the respective chairs of the Board committees.

Compensation Committee Interlocks and Insider Participation

The members of the Company’s Human Capital and Compensation Committee in 2023 were Ms. Burgess, Mr. Dearth, Dr. Delgado, Ms. Reed (Chair) and Mr. Wehmer. Gregory E. Lawton also served as a member and Chair of the Human Capital and Compensation Committee until his term as a director ended upon his passing on August 18, 2023. None of the members of the Human Capital and Compensation Committee during 2023 were at any time an officer or employee of the Company nor did any member participate in a Related Party Transaction. In 2023, none of the Company’s executive officers served as a member of the compensation committee of another entity, or as a director of another entity, one of whose executive officers served on the Human Capital and Compensation Committee or as one of the Company’s directors.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Summary of Executive Compensation in 2023

In 2023, the Company and the Human Capital and Compensation Committee of the Board of Directors (the “Committee”) applied the compensation policies and principles described in this Compensation Discussion and Analysis in determining the compensation for the individuals named in the Summary Compensation Table. Those individuals are referred to herein as the named executive officers (“NEOs”). The NEOs for 2023 were:

NEO |  | Title
Scott R. Behrens |  | President and Chief Executive Officer
Luis E. Rojo |  | Vice President and Chief Financial Officer
Robert J. Haire, Jr. (1) |  | Executive Vice President, Supply Chain
David G. Kabbes (2) |  | Vice President, General Counsel and Secretary
Sean T. Moriarty |  | Vice President and General Manager – Surfactants
Arthur W. Mergner (3) |  | Former Executive Vice President, Supply Chain

(1) | Mr. Haire joined the Company as Executive Vice President, Supply Chain, on May 1, 2023.

(2) | Mr. Kabbes also served as the Company’s Interim Chief Human Resources Officer from April 3, 2023, through September 17, 2023.

(3) | Mr. Mergner served as the Company’s Executive Vice President, Supply Chain until his retirement on July 3, 2023.

Significant Developments in 2023

Company Performance

| (1) | In 2023, the Company reported net income of $40.2 million, or $1.75 per diluted share, compared to $147.2 million, or $6.38 per diluted share, in 2022, a 73% decrease. The Company’s adjusted net income was $50.7 million, or $2.21 per diluted share, versus $153.5 million, or $6.65 per diluted share, in 2022, a 67% decrease.1

| (2) | The Surfactant segment delivered operating income of $72.4 million, a 56% decrease versus prior year. The Polymer segment delivered $60.8 million of operating income, a 27% decrease versus the prior year. Specialty Product operating income was $11.5 million, a 62% decrease versus prior year.

| (3) | For the full year, the Company paid $32.9 million of dividends. With the increased cash dividend in the fourth quarter of 2023, the Company has increased the dividend on its Common Stock for the 56th consecutive year.

Key Developments Impacting Executive Compensation

| (1) | The Company’s advisory Say-on-Pay vote was supported by 98% of votes cast at the Company’s 2023 Annual Meeting.

1 Adjusted net income is a financial measure that has not been calculated pursuant to U.S. generally accepted accounting principles (“GAAP”). See Appendix A for further discussion and a reconciliation of this non-GAAP financial measure to net income, the most directly comparable GAAP financial measure.

18

| (2) | Due to the Company’s 2023 financial performance, and regardless of the level of achievement of individual performance goals, the NEOs did not receive any annual incentive awards for 2023. In addition, and also as a result of failing to meet certain financial goals, the performance shares that were granted to the NEOs in February 2023 under the Company’s long-term incentive plan were forfeited.

| (3) | After considering all components of the total compensation paid to the NEOs in 2023, the Committee determined that the 2023 NEO compensation was competitive, reasonable, and aligned with both Company performance and stockholder interests.

Executive Compensation Best Practices the Company Follows

What We Do |  | What We Don’t Do
✓ |  | Pay for Performance—a Majority of our NEOs’ Annual Total Compensation is Variable and At-Risk |  | O |  | No Grants of Discounted Stock Options or Stock Appreciation Rights
✓ |  | Align Executives’ Total Compensation Mix with Stockholders’ Interests |  | O |  | No Repricing or Replacing Outstanding Stock Options or Stock Appreciation Rights Without Stockholder Approval
✓ |  | Require Significant Executive Stock Ownership |  | O |  | No Employment Agreements That Guarantee Employment or Compensation
✓ |  | Limit Performance-Based Incentive Awards to a Maximum of 200% of Target |  | O |  | No Standing Individual Severance or Change-in-Control Agreements
✓ |  | Provide Limited Executive Perquisites |  | O |  | No Use of Excise Tax Gross-Ups
✓ |  | Subject Incentive Compensation to a Clawback Policy |  | O |  | No Dividend Payments on Unearned Performance Shares

Compensation Philosophy

The basic premise of the Company’s executive compensation philosophy is to pay for performance. The Company’s intention is to foster a performance-driven culture with competitive total compensation as a key driver for all employees. Compensation levels commensurate with Company performance are designed to align the interests of our employees with the interests of our stockholders. To better align our NEOs’ compensation with the interests of our stockholders, a substantial portion of compensation is at-risk and performance-based.

The Company’s guiding philosophy in setting executive compensation is that the compensation of executive officers should reflect the scope of their job responsibilities and the level of individual and corporate performance achieved. Executive compensation should be competitive internally and externally with like or comparable positions based on job descriptions and responsibilities at similarly sized companies within the Company’s industry, Peer Group (as defined below) and other appropriate related industry data or survey information. The Company’s compensation philosophy is reviewed at least annually by the Committee.

The effectiveness of the executive compensation program is primarily measured by Company performance, stock price, external market dynamics, the ability of the Company to attract and retain executive officers, and comparison against other relevant, external benchmarks as needed.

The Committee generally does not consider the impact of previously awarded compensation in determining current executive total compensation. The Committee does, however, use both a chemical

19

industry peer group as well as aggregate executive compensation survey data to annually assess executive compensation as described below under “Compensation Peer Group and Survey Data.” Except for the limits regarding incentive compensation as described below, the Committee does not use specific policies to allocate between cash and non-cash compensation or between short-term and long-term compensation.

Compensation Objectives

The overall objectives of the Company’s compensation program (in which each NEO participates) are as follows:

| • |  | motivate employees to achieve and maintain a high level of performance, and drive results that will help the Company achieve its goals;

| • |  | align the interests of our employees with the interests of our stockholders;

| • |  | provide for market-competitive levels of compensation; and

| • |  | attract and retain employees of outstanding ability.

Role of the Human Capital and Compensation Committee

The Committee is responsible for overseeing the establishment and administration of the Company’s policies, programs and procedures for compensating the Company’s executive management, as further described below. The Committee is also responsible for providing advice to the Company regarding executive development and succession planning. The Committee may, in its discretion, delegate all or a portion of its duties and responsibilities to a subcommittee or, to the extent permitted by applicable law, to any other body or individual.

Role of the Compensation Consultant

The Committee engaged Exequity LLP (“Exequity”) as its independent compensation consultant for 2023. Exequity advises the Committee on a range of executive compensation matters. The scope of Exequity’s services to the Committee includes, but is not limited to, the following:

| • |  | Providing the Committee with an assessment of the market competitiveness of the Company’s executive compensation.

| • |  | Apprising the Committee of executive compensation-related trends and developments in the marketplace.

| • |  | Informing the Committee of regulatory developments relating to executive compensation practices.

| • |  | Assisting the Committee with goal setting, calibrating levels of pay to various levels of performance, and pay for performance alignment.

| • |  | Comparing Company executive compensation plan designs and practices to the marketplace.

| • |  | Recommending changes to the executive compensation program to maintain competitiveness and ensure consistency with business strategies, good governance practices and alignment with stockholder interests.

20

Exequity reports directly to the Committee. The Committee conducted its annual assessment of Exequity’s independence pursuant to SEC rules and determined that no conflict of interest exists that would prevent Exequity from independently advising the Committee. Exequity does not provide any other services to management or the Company.

Role of the Committee and Executives in Establishing Executive Compensation

The Committee determines the compensation of the Chief Executive Officer. The Chief Executive Officer and Vice President and Chief Human Resources Officer make recommendations to the Committee regarding compensation for all other executive officers, including the NEOs, other than with respect to their own compensation. The Committee then reviews these recommendations and approves the final compensation for all executive officers. All recommendations made to the Committee and all determinations made by the Committee are based upon the Company’s policies and guidelines and other relevant factors outlined in the “Compensation Peer Group and Survey Data” and “Elements of Compensation” sections below.

Advisory Vote on Executive Compensation

The advisory vote in 2023 was the thirteenth consecutive year that the Company’s Say-on-Pay vote was supported by its stockholders with the approval of more than 96% of the votes cast at the annual meeting of stockholders. As stated above, the Company’s advisory Say-on-Pay vote was supported by 98% of votes cast at the Company’s 2023 Annual Meeting. The Committee acknowledges and values the feedback from the Company’s stockholders on the annual Say-on-Pay vote and believes that these results demonstrate stockholder support of the Company’s executive compensation programs. As a result of the strong stockholder support for the 2023 Say-on-Pay vote, the Committee determined that the Company’s compensation practices and processes did not require any significant modifications to achieve the desired results of the Company’s compensation program or to address stockholder concerns and therefore did not make any changes as a direct result of such vote results. The Committee will continue to consider the outcome of these advisory votes when determining future executive compensation arrangements.

21

Executive Pay Mix

The Company targets a total compensation mix where fixed pay, consisting of base salary, is less than half of the total compensation that any NEO or executive officer may earn in any given year. The combined mix of both short-term and long-term incentives for executive officer compensation is structured to encourage the necessary focus and motivation to achieve outstanding results on an ongoing basis, both in the short term and long term. In addition, the combined focus on both short-term and long-term objectives is designed to align executive officers’ and stockholders’ interests. Short-term incentives for executive officers are based on individual and Company performance. Long-term incentives for executive officers are based on Company performance (performance shares) or are time-vested (RSUs and SARs). The Company’s total compensation targets assume above-average Company performance, and potential compensation can vary considerably depending on overall Company performance. The graphics below illustrate the pay mix for our Chief Executive Officer and other NEOs other than Mr. Mergner, who retired on July 3, 2023, (on an average basis) using target level of performance for all incentive awards.

Compensation Peer Group and Survey Data

To better understand the compensation practices of similar companies, the Committee reviews data gathered from a custom peer group (“Peer Group”) and general market survey data from Mercer LLC (“Mercer”). Information gathered from the Peer Group serves as the primary reference point for the Committee, with Mercer survey data used as a secondary reference.

The Peer Group consists of companies selected on the basis of chemical industry affiliation and size as compared to the Company (e.g., total revenues and market capitalization). The following companies comprised the Peer Group that the Committee referenced when setting 2023 compensation:

AdvanSix Inc. |  | The Chemours Company |  | NewMarket Corporation
Ashland Inc. |  | H.B. Fuller Company |  | Quaker Chemical Corporation
Avient Corporation |  | Innospec Inc. |  | RPM International Inc.
Cabot Corporation |  | Koppers Holdings, Inc. |  | Sensient Technologies Corporation

The Committee undertakes annual evaluations of the Peer Group in order to ensure the Company is comparing itself with companies that have the characteristics to appropriately match the Company. Exequity performed a review of the Peer Group listed above in July 2023 and the Committee did not make changes to the Peer Group as a result of such review. The Committee and its independent compensation consultant will continue to monitor the Peer Group going forward as appropriate.

22

When assessing the competitiveness of Company compensation programs, the Committee, in part, uses median compensation levels in the Peer Group as a reference point to provide a framework for and on which to base individual compensation decisions. The Committee generally references median total compensation for executive officers, but the Committee retains discretion to determine appropriate compensation levels. The Committee believes that all NEOs’ and executive officers’ total compensation amounts are within appropriate and reasonable levels as compared to the Peer Group data considering performance, experience level, time in position and both external and internal equity evaluations.

Elements of Compensation

For the fiscal year ended December 31, 2023, the principal elements of compensation for the executive officers, including the NEOs, were as follows:

Compensation Element
Purpose |  | Description
Base Salary
To attract and retain employees of outstanding abilities |  | Fixed component of pay based on specific position salary ranges determined by job responsibilities and performance, time in position at the Company and reference to Peer Group data
Short-Term Incentive Compensation
To drive improvement in year-over-year financial performance; to motivate, attract and retain employees; and to align executives’ interests directly with Company financial objectives |  | Variable, annual, at-risk cash component of pay that rewards achievement of pre-determined Company and individual goals
Long-Term Incentive Compensation
To promote retention of executives, to reward outstanding Company performance, to encourage a focus on the Company’s long-term financial results, and to align executive interests with stockholder interests |  | Variable, at-risk, equity component of pay for eligible participants that rewards stockholder value creation over the long term
Retirement Benefits, Perquisites and Other Benefits
To promote retention, to attract outstanding employees and to provide employees with a tax deferred retirement savings vehicle directly connected to the Company’s financial results |  | Company dollar-for-dollar matching contribution up to six percent of base salary under a Savings and Investment Retirement Plan for all U.S. employees, plus supplemental contributions based on the Company’s financial results Executives and key employees, including the NEOs, are eligible for a limited amount of perquisites Benefit programs that are available to all U.S. salaried employees

23

Base Salary

The Company has established salary grades and ranges for all global employees, including the NEOs. Salary grades reflect the responsibility level of the position (i.e., positions with a greater level of responsibility have a higher salary grade). The salary range for each grade is primarily based on survey data. The salary grade structure enables the Company to ensure that pay is both market competitive and internally equitable.

The Committee, taking into consideration the performance of the Company, the Company’s compensation philosophy, the Peer Group data, and the executive’s performance, reviews and determines the Chief Executive Officer’s salary on an annual basis. The Chief Executive Officer and the Vice President and Chief Human Resources Officer make recommendations to the Committee regarding compensation for all other NEOs. The Committee has the discretion to approve such recommendations or revise the recommended amounts, higher or lower, based upon each executive officer’s individual performance. The Chief Executive Officer’s salary range is determined based on the same factors and criteria as those for the other NEOs and executive officers.

The NEOs’ base salaries, effective as of March 1, 2023 (unless otherwise noted), are shown below. The NEOs’ base salaries were increased slightly to bring them more in line with the market.

NEO |  | 2022 Base Salary |  |  | 2023 Base Salary |
Scott R. Behrens |  | $ | 900,000 |  |  | $ | 940,000 |
Luis E. Rojo |  | $ | 515,000 |  |  | $ | 546,000 |
Robert J. Haire, Jr. (1) |  |  | N/A |  |  | $ | 460,000 |
David G. Kabbes |  | $ | 445,000 |  |  | $ | 464,000 |
Sean T. Moriarty |  | $ | 440,000 |  |  | $ | 462,000 |
Arthur W. Mergner |  | $ | 480,000 |  |  | $ | 490,000 |

(1) | Mr. Haire joined the Company on May 1, 2023.

Short-Term Incentive Compensation

NEOs and certain other employees are eligible for short-term incentive compensation as set forth in the Management Incentive Plan. The purpose of the Company’s short-term incentive compensation program is to promote improvement in year-over-year financial performance; to motivate, attract and retain executive, managerial and key employees of outstanding ability; and to align participants’ interests directly with the Company’s financial targets. The target amount of short-term incentive compensation for each NEO is expressed as a percentage of the executive’s actual base salary earned during the respective calendar year. Because senior managers have a greater ability to impact Company results, a significant percentage of their total target compensation is at-risk. The Chief Executive Officer position has the highest level of responsibility, and therefore, the target percentage exceeds the other NEOs’ target percentages.

The extent, if any, to which an incentive award will be payable to an NEO will be based solely upon the degree of achievement of pre-established performance goals over the specified calendar year. In years when Company performance is exceptional and above the Target level, it is possible for NEOs to receive annual incentive payments above Target, while in years when Company or individual performance is below the Threshold level for a particular metric, no annual incentive will be paid based upon performance on that metric. In addition, the Committee may, in its sole discretion, reduce or eliminate the amount that would otherwise be payable to the NEO with respect to a calendar year.

24

The following chart reflects the Target Annual Incentive Award and Maximum Annual Incentive Award for each NEO for 2023 under the terms of the Management Incentive Plan (which target amounts were the same as for 2022 for each NEO who was employed by the Company in 2022):

NEO |  | Target Annual Incentive Award (% of 2023 Salary Earned) |  | Maximum Annual Incentive Award (% of 2023 Salary Earned)
Scott R. Behrens, |  | 100.0% |  | 200.0%
Luis E. Rojo |  | 75.0% |  | 150.0%
Robert J. Haire, Jr. |  | 75.0% |  | 150.0%
David G. Kabbes |  | 65.0% |  | 130.0%
Sean T. Moriarty |  | 75.0% |  | 150.0%
Arthur W. Mergner |  | 75.0% |  | 150.0%

Each NEO’s annual incentive payment is determined based on the Company’s achievement of overall financial performance objectives (“Corporate Financial Performance Objectives”) and the achievement of individual performance objectives (“Individual Performance Objectives”), as described below. For 2023, each NEO’s Annual Incentive Award could be increased by a prorated amount if Corporate Net Income exceeded the Target objective, with a two times multiplier applied if Corporate Net Income met or exceeded the Maximum objective. Similarly, each NEO’s Annual Incentive Award could be reduced if Corporate Net Income did not meet the Threshold objective.

Corporate Financial Performance Objectives

The Committee establishes the Corporate Financial Performance Objectives at the beginning of each calendar year. For 2023, the Committee established targets for the two Corporate Financial Performance Objectives for all NEOs: Corporate Net Income and Corporate Growth Goal.2

For 2023, the following performance levels were established for the Corporate Net Income objective:

|  | Threshold |  | Target |  | Maximum
Corporate Net Income |  | $130.0 million |  | $145.0 million |  | $160.0 million

The Corporate Growth Goal consisted of profit goals for three categories of products and customers. Together, the three categories of products and customers had an assigned profit goal, with a target increase over 2022 profit. The Corporate Growth Goal was based upon strategic growth priorities for the Company and was designed to be difficult but achievable. The Corporate Growth Goal consisted of profit growth in the following categories: Rigid Polyols, Functional Surfactants and Tier 2 and Tier 3 Surfactant Customers.

For 2023, the following performance levels were established for the Corporate Growth Goal with reference to the profit achieved:

|  | Threshold |  | Target
Corporate Growth Goal |  | $667.0 million |  | $715.5 million

Each NEO’s annual incentive objectives include these Corporate Financial Performance Objectives. For 2023, all NEOs had at least 35% of their annual incentives tied to these objectives. Within the Corporate Financial Performance Objectives, a weighting of approximately 85% was assigned to the Corporate Net Income objective and a weighting of approximately 15% was assigned to the Corporate Growth Goal objective.

2 Corporate Net Income is a non-GAAP measure that differs from the Company’s reported net income. See Appendix A for a definition.

25

The following table shows the Company’s performance against the Corporate Net Income and Corporate Growth Goal objectives in 2023:

Objective |  | 2023 Results |  | 2023 Threshold |  | Annual Incentive Award Earned (% of 2023 Salary Earned)
Corporate Net Income |  | $  50.7 million |  | $ 130.0 million |  | 0%
Corporate Growth Goal |  | $ 593.9 million |  | $ 667.0 million |  | 0%

For 2023, the Company did not meet the Corporate Net Income Threshold objective of $130.0 million, with a result of $50.7 million, and did not meet the Corporate Growth Goal Threshold objective of $667.0 million, with a result of $593.9 million. Because the Company did not meet the Threshold Corporate Financial Performance Objectives, the NEOs did not earn any portion of their Annual Incentive Awards for 2023.

Individual Performance Objectives

The President and Chief Executive Officer and the Committee agreed upon the Individual Performance Objectives for the President and Chief Executive Officer at the beginning of 2023. For executives other than the Chief Executive Officer, the Chief Executive Officer and the executive agree upon Individual Performance Objectives at the beginning of each calendar year. These Individual Performance Objectives may either be financial objectives for a particular business segment or function, or achievement of certain strategic objectives specific to their function and responsibility. For 2023, the Chief Executive Officer’s Individual Performance Objectives included enhancing long-term Company performance by championing core culture and values, including safety, compliance, and employee engagement and accountability, as well as specific operational objectives in areas such as supply chain and capital project execution. For each business segment leader, the financial performance of the executive’s segment comprises a significant portion of the executive’s Individual Performance Objectives. For example, for 2023, global surfactant operating income comprised 30% of the short-term incentive compensation objectives for Mr. Moriarty, the Company’s Vice President and General Manager – Surfactants.

As stated above, as a result of the Company’s 2023 financial performance, and notwithstanding achievement of any Individual Performance Objectives, the NEOs did not earn any annual incentive awards for 2023.

Long-Term Incentive Compensation

The Committee typically grants equity awards annually to the NEOs under the Company’s long-term incentive plan. In 2023, the Committee reviewed and approved an allocation of long-term incentives for the NEOs at approximately 25% of the total grant value as SARs, approximately 25% of the total grant value as RSUs and approximately 50% of the total grant value as performance shares. The Committee changed the equity award mix to add RSUs in 2023 in order to better align with market practice.

NEO |  | Stock Appreciation Rights Value |  |  | Restricted Stock Units Value |  |  | Performance Shares Value |  |  | Total 2023 LTI Value |
Scott R. Behrens |  |  | $ 780,000 |  |  |  | $ 780,000 |  |  |  | $ 1,560,000 |  |  |  | $ 3,120,000 |
Luis E. Rojo |  |  | $ 225,000 |  |  |  | $ 225,000 |  |  |  | $   450,000 |  |  |  | $   900,000 |

David G. Kabbes |  |  | $ 150,000 |  |  |  | $ 150,000 |  |  |  | $   300,000 |  |  |  | $   600,000 |
Sean T. Moriarty |  |  | $ 150,000 |  |  |  | $ 150,000 |  |  |  | $   300,000 |  |  |  | $   600,000 |
Arthur W. Mergner |  |  | $ 168,750 |  |  |  | $ 168,750 |  |  |  | $   337,500 |  |  |  | $   675,000 |

26

The chart below shows the number of each type of equity award that the Committee granted to the NEOs as part of the annual 2023 equity grant. The number of SARs granted was calculated by dividing the amounts in the table above by the Black-Scholes value of a SAR on the date of the grant. The number of RSUs and performance shares granted was calculated by dividing the amounts in the table above by the average of the opening price and closing price of the Company’s common stock on the date of the grant.

NEO |  | Stock Appreciation Rights |  |  | Restricted Stock Units |  |  | Performance Shares (at Target) |
Scott R. Behrens |  |  | 19,742 |  |  |  | 7,096 |  |  |  | 14,192 |
Luis E. Rojo |  |  | 5,695 |  |  |  | 2,047 |  |  |  | 4,094 |
Robert J. Haire, Jr. |  |  | 4,744 |  |  |  | 1,649 |  |  |  | 3,299 |
David G. Kabbes |  |  | 3,797 |  |  |  | 1,365 |  |  |  | 2,729 |
Sean T. Moriarty |  |  | 3,797 |  |  |  | 1,365 |  |  |  | 2,729 |
Arthur W. Mergner |  |  | 4,271 |  |  |  | 1,535 |  |  |  | 3,070 |

The grants of SARs, RSUs and performance share awards to the NEOs are shown in the Grants of Plan-Based Awards Table. The Board of Directors believes that the mix of such awards provides long-term incentive compensation that is market competitive to attract and retain executives who drive the long-term growth of the Company and further align the interests of those executives with the interests of the Company’s stockholders.

In addition to the annual long-term incentive awards, grants of SARs, RSUs, performance shares and other stock awards may be awarded to executive officers at other times based on factors that the Committee determines to be relevant, including upon hire, upon promotion or for extraordinary job performance. In recognition of his service as Interim Chief Human Resources Officer during 2023, Mr. Kabbes was awarded, in addition to the grants set forth above, a grant of 762 RSUs with a value of $50,000 in October 2023.

Stock Appreciation Rights

SARs are granted annually at the average of the opening price and closing price of Common Stock on the date of the grant and have a ten-year term. SARs vest ratably over a three-year period and are settled in stock.

Restricted Stock Units

RSUs are granted annually at the average of the opening price and closing price of Common Stock on the date of the grant. RSUs vest ratably over a three-year period and are settled in stock.

Performance Shares

Performance shares are contingently awarded at a target number of shares and subject to certain performance conditions established by the Committee. The Committee chose Corporate Net Income as a performance measure because the Company uses net income as an important indicator of business performance. The Company uses an adjusted measure, rather than reported net income, because the adjusted measure excludes items that may not be indicative of the Company’s core operating results. The initial target number of shares may increase or decrease by up to 50% based on the Company’s Corporate Net Income results for the calendar year in which the grant is made versus Threshold, Target and Maximum Corporate Net Income objectives. If the Company’s Corporate Net Income result for such year is below the Threshold objective, then the performance shares are forfeited entirely. If the Company’s Corporate Net Income result for such year exceeds the Maximum objective, then the target number of shares will be increased by 50%. Following completion of the three-year

27

performance period, the number of shares may further increase or decrease by up to 30%, based on a three-year average Corporate Return on Invested Capital (“ROIC”) modifier.3 For the performance shares granted in 2023, the Committee set the following Corporate Net Income objectives:

Performance Level |  | 2023 Corporate Net Income |  |  | Initial Share Award (% of Target)
Threshold |  | $ | 130 million |  |  | 50%
Target |  | $ | 145 million |  |  | 100%
Maximum |  | $ | 160 million |  |  | 150%

The Committee set the following ROIC modifiers for the three-year performance period ending December 31, 2025:

2023-2025 Average ROIC |  | Award Modifier
Less than or equal to 6.75% |  | -30%
7.50% |  | No impact
Equal to or greater than 8.25% |  | +30%

The 2023 Corporate Net Income result of $50.7 million was below the Threshold objective level. Therefore, the performance shares granted in 2023 were forfeited and no shares will be earned or issued in respect thereof.

For the performance shares granted in 2021, the initial calculation of the number of performance shares was based on the following Corporate Net Income objectives:

Performance Level |  | 2021 Corporate Net Income |  |  | Initial Share Award (% of Target)
Threshold |  | $ | 116 million |  |  | 50%
Target |  | $ | 145 million |  |  | 100%
Maximum |  | $ | 159 million |  |  | 150%

The Committee determined the actual number of performance shares issued after the three-year performance period ending December 31, 2023, based on the following ROIC modifiers:

2021-2023 Average ROIC |  | Award Modifier
Less than or equal to 9.75% |  | -30%
10.75% |  | No impact
Equal to or greater than 11.75% |  | +30%

3 Return on Invested Capital is a non-GAAP measure. See Appendix A for a definition.

28

The 2021 Corporate Net Income result was $143.5 million and the 2021-2023 average ROIC result was 8.08%. Therefore, the number of shares earned and issued for the 2021 grant of performance shares was 68.18% of the initial target number of shares. The following chart reflects the number and value of shares earned and issued in respect of the performance shares granted in 2021.

Name |  | Number of Shares Acquired on Vesting (#) |  |  | Value Realized on Vesting ($) (2) |
Scott R. Behrens |  |  | 2,205 |  |  | $ | 202,606 |

Retirement Benefits

Retirement Plan for Salaried Employees

Effective June 30, 2006, the Company froze the Retirement Plan for Salaried Employees (the “Retirement Plan for Salaried Employees”) and ended the benefit accrual for all participants. Eligible participants were all employees not covered by a collective bargaining agreement who were employees prior to July 1, 2006. The Retirement Plan for Salaried Employees was replaced by the Savings and Investment Retirement Plan (“SIRP”), which provides for Company contributions into the employee’s SIRP account (see the discussion below in the “Savings and Investment Retirement Plan” section). The primary purpose of both the Retirement Plan for Salaried Employees and the SIRP is to retain valuable employees.

The amounts included in the Pension Benefits table are the present values of the benefits expected to be paid under the Retirement Plan for Salaried Employees in the future. The amount of each future payment is based on the current accrued pension benefit. The actuarial assumptions, with the exception of the expected retirement age, are consistent with those used in the Company’s financial statements. The retirement age is the earliest unreduced retirement age as defined in the Retirement Plan for Salaried Employees and the SIRP.

The pension benefit information set forth in this proxy statement has been calculated based on actuarial assumptions that are considered to be reasonable. Other actuarial assumptions could also be considered to be reasonable, which would result in different pension benefit estimates.

Savings and Investment Retirement Plan

Pursuant to the SIRP, in each payroll period during 2023, the Company made a contribution to the SIRP account of each eligible employee, including the NEOs. The amount of the Company contribution in 2023 was a dollar-for-dollar matching contribution of up to six percent of the participant’s base salary for the portion of the payroll period during which the participant was an eligible employee (subject to certain limits). All the NEOs received SIRP contributions in 2023 in the amounts set forth in the Summary Compensation Table.

29

Profit-Sharing Contributions

The Company may make additional profit-sharing contributions under the SIRP to each eligible employee, including the NEOs and salaried, hourly and union employees. The Company’s profit-sharing contributions are designed to (i) provide eligible employees with an element of their retirement savings that is directly connected to the Company’s financial results, (ii) provide a tax-deferred retirement savings vehicle for eligible employees while giving participants the incentive to optimize the Company’s financial results, and (iii) allow eligible employees to enjoy the benefits of the Company’s success.

Each year management determines, based on the Company’s financial results, whether to recommend to the Committee that the Company make a profit-sharing contribution to the accounts of eligible participants. The Committee reviews management’s recommendation and, if approved, presents the recommendation to the Board of Directors for approval. In 2023, the Committee recommended a profit-sharing contribution that was based on 2.5% of the Company’s 2022 pre-tax income, which was approved by the Board.

Employee Stock Ownership Plan

The Stepan Company Employee Stock Ownership Plan II (“ESOP II”), which is applicable to NEOs, is designed to (i) expand stock ownership among employees, (ii) encourage greater employee interest in the Company’s financial results, (iii) benefit employees financially by enabling them to acquire shares of the Company’s Common Stock without making contributions, and (iv) provide eligible employees with the opportunity to share in the growth of the Company.

Contributions to ESOP II are a part of the profit-sharing contribution under the SIRP as described in the “Profit-Sharing Contributions” section above and may be reallocated to ESOP II in shares of Company Common Stock. The ESOP II allocation is made to broaden Company stock ownership among employees for further alignment with the interests of Company stockholders. For 2023, the Committee approved a 100% allocation to ESOP II for eligible U.S. employees, including the NEOs.

Supplemental Executive Savings and Investment Retirement Contributions

The Board of Directors has the authority to approve supplemental contributions to provide retirement benefits to any executive affected by IRS limits on benefits that otherwise would be available through contributions to the SIRP. The supplemental contributions are provided to executives as a common executive benefit that allows the Company to be competitive for executive compensation and benefits. During 2023, all the NEOs were eligible to receive supplemental contributions in the amount by which a six percent contribution to the NEO’s SIRP account by the Company would exceed IRS limits. All supplemental contributions to the NEOs in 2023 are included in the Summary Compensation Table.

Perquisites

The Company provides NEOs with limited perquisites that the Company and the Committee believe are reasonable and consistent with the Company’s overall compensation program because they better enable the Company to attract and retain superior employees for key positions. The Committee periodically reviews the perquisites provided to the NEOs and other executives.

The Company offers additional long-term disability “top-up” coverage to employees, including NEOs, whose long-term disability coverage is limited due to payout caps under the long-term disability coverage offered to all U.S. salaried employees.

30

All executives at the Vice President level and higher, including the NEOs, are provided the use of Company-leased vehicles, including fuel, maintenance and insurance. The allowance for the initial vehicle cost is set by salary grade. The personal use value is computed using the IRS annual lease valuation rule. Other travel benefits, including spousal travel on a limited basis, are provided periodically. The Company also provides relocation benefits for newly hired executive officers.

The Company maintained one Company-owned condominium that is not used solely for business purposes. Executives, including the NEOs, are allowed to use this property for personal use if and when the property is not needed for business purposes. When the NEOs use this property for personal reasons, such values are included in the Summary Compensation Table under “All Other Compensation” based on the incremental cost to the Company.

Clawback Policy

The Company has adopted a Clawback Policy that applies to the Company’s executive officers who are subject to Section 16 of the Exchange Act. The current version of the policy applies to compensation received on or after October 2, 2023, and is intended to comply with applicable SEC and New York Stock Exchange requirements. Under this policy, in the event of a restatement of the Company’s financial statements, the Company will recover from all covered executives, regardless of fault and without regard to any taxes paid, compensation that would not have been paid had the restated financial statements initially been correct. The compensation that could be recovered includes short-term and long-term incentive compensation awarded based on the subsequently restated financial statements that was paid during the three completed fiscal years preceding the restatement. The previous version of the policy applies to compensation received prior to October 2, 2023. Under that version of the policy, in the event that any executive covered by the policy engages in willful misconduct or fraud that substantially contributes to a material restatement of the Company’s financial statements, the Company will recover from all covered executives compensation that would not have been paid had the restated financial statements initially been correct. The compensation that could be recovered includes short-term and long-term incentive compensation awarded based on the subsequently restated financial statements that was paid during the 12 months preceding the restatement.

Stock Ownership Policy

The NEOs are subject to a stock ownership policy. The Company instituted a stock ownership policy because it believes that ownership of Company stock is desirable in order to focus both short-term and long-term decision-making on the best interests of the Company and its stockholders. Ownership of Company stock aligns NEOs’ interests with the Company’s financial performance, including the performance of the Company’s Common Stock.

The stock ownership policy, last amended in December 2022, is reviewed by the Committee, as needed, on a periodic basis against peer group and general industry benchmarks of stock ownership.

The stock ownership guidelines apply to all NEOs and certain other employees. The Company’s Chief Executive Officer is required to maintain ownership of shares with a value of at least five times his base salary; each other executive officer is required to maintain ownership of shares with a value of at least two and a half times his or her base salary; and each other participant is required to maintain ownership of shares with a value of at least one times his or her base salary. All executives, including the NEOs, are expected to reach and maintain the required stock ownership level within five years from their initial stock grant. In the event of a promotion that would require an increase in stock ownership under the terms of the policy, an executive has five years from the date of the promotion to achieve compliance with the new level of stock ownership requirements. During the first thirty-six months of eligibility, all executives, including the NEOs, are encouraged, but not required, to progress toward compliance by making

31

approximately twenty percent progress each year. After thirty-six months of eligibility, all executives, including the NEOs, are required to demonstrate progress toward the stock ownership requirement by attaining eighty percent of the required level by year four and one hundred percent of the required level by year five. Recognizing the importance of retirement planning, an NEO may, commencing at age 61, reduce his or her holdings by ten percent per year up to fifty percent of his or her required ownership level by the calendar year he or she attains the age of 65.

The following shares count towards the stock ownership requirements: (i) shares owned directly or indirectly(ii) shares owned in the Company’s ESOP II, (iii) shares owned in the Company’s Employee Stock Purchase Plan, (iv) shares held in any Company deferred compensation plan, (v) time-based restricted stock awards and (vi) unvested performance shares no longer subject to performance conditions. Stock options and SARs do not count towards the stock ownership requirement. No shares other than those stated above count toward the stock ownership requirements.

The Committee reviews annually whether executives, including the NEOs, are in compliance with the stock ownership policy. The Committee determined that all executive officers, including the NEOs, were in compliance with the Company’s stock ownership requirements as of March 2024. Executive officers who received their initial stock grant over five years ago are in full compliance and executive officers who received their initial stock grant within the last five years have made the requisite progress towards full compliance. If an executive fails to comply with stock ownership policy and annual progress requirements, the executive must retain 100% of their vested long-term incentive plan shares. In addition, all executives, including NEOs, are prohibited from selling Company stock acquired by exercising stock options until such executive is in compliance with the ownership requirement.

Hedging and Trading Restrictions

The Company has an Insider Trading Policy that, among other things, prohibits NEOs, officers, directors and employees from hedging the economic risk of their ownership in the Company’s Common Stock. This policy bars NEOs, officers, directors and employees from purchasing financial instruments or otherwise engaging in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of Company equity securities granted by the Company as compensation or held, directly or indirectly, by the NEO, officer, director or employee. In addition, this policy prohibits short-selling of the Company’s securities. This policy also prohibits directors, officers and covered employees from trading in the Company’s securities outside of trading window periods or without pre-clearance.

Post-Termination Benefits

The Company does not maintain any plans or other arrangements with its executives that provide for severance or post-termination compensation in the event of a future termination of the executive’s employment. Subject to Committee approval, the Company may, however, occasionally enter into separation agreements or arrangements with its executives at the time of the executive’s termination of employment that provide for severance payments or benefits. In addition, executives and other employees may receive accelerated vesting of equity awards in the event of death or disability, and prorated accelerated vesting of equity awards in the event of retirement, pursuant to the terms of the applicable grant agreements.

Impact of Tax and Accounting Considerations

The Company monitors compensation and benefits-related accounting rules, securities rules, tax rules and all other federal and state regulations on an ongoing basis through internal sources and external sources such as consultants, advisors and outside legal counsel. The Company routinely considers such rules and regulations and their impact on plan design alternatives and Company performance.

The number of shares that vest following the ROIC performance period ending December 31, 2024, will be determined based on the number of shares earned for the one-year Corporate Net Income measurement period ended December 31, 2022, with the shares earned increased or decreased based on the average ROIC achieved for the three-year period ending December 31, 2024. The number of shares that vest following the ROIC performance period ending December 31, 2025, will be determined based on the number of shares earned for the one-year Corporate Net Income measurement period ended December 31, 2023, with the shares earned increased or decreased based on the average ROIC achieved for the three-year period ending December 31, 2025. The number of shares reported for awards with a performance period ending December 31, 2024, is based on achieving Maximum Corporate Net Income performance with the ROIC modifier for Threshold performance because the Company exceeded Target Corporate Net Income and did not meet Threshold ROIC performance in the applicable measurement period. The number of shares reported for awards with a performance period ending December 31, 2025, is based on achieving Threshold Corporate Net Income performance with the ROIC modifier for Threshold performance. Because the Company did not meet Threshold Corporate Net Income in the applicable measurement period, no amounts will be earned for awards with a performance period ending December 31, 2025.

2023 Pension Benefits

The pension values included in the table below are the present value of the benefits expected to be paid in the future under the Company’s Retirement Plan for Salaried Employees. The amount of each future payment is based on the current accrued pension benefit and the values of the benefits issued under these plans are determined using interest rate and mortality rate assumptions consistent with those used in the Company’s financial statements. The retirement age is the earliest unreduced retirement age as defined in each plan. The Company froze the Retirement Plan for Salaried Employees in 2006. Further information regarding the Company’s Retirement Plans is provided above in the Compensation Discussion and Analysis.

For the Retirement Plan for Salaried Employees amounts included in the Present Value of Accumulated Benefit column, the normal retirement benefit is based on the following formula:

| • |  | 50% of final average earnings less 50% of the participant’s primary Social Security benefit multiplied by service up to 30 years divided by 30.

| • |  | Normal Retirement: Age 65.

| • |  | Early Retirement: Retirement before age 65 but after attaining age 55 and completing five years of vesting service. The normal retirement benefit is reduced by 0.33% per month for each month between the date on which payments begin and the date of the participant’s 63rd birthday. Arthur W. Mergner is eligible to begin early retirement benefits.

| • |  | Service: Credited from the date of hire to June 30, 2006, with a maximum of 30 years.

| • |  | Final Average Earnings: Highest consecutive five years of base compensation during last ten years of service through June 30, 2006. This amount is limited for the Retirement Plan for Salaried Employees to the amount allowed by the Internal Revenue Code of 1986, as amended (the “Code”) regulations.

The specific assumptions used in estimating the amounts in the Present Value of Accumulated Benefit column include:

| • |  | Assumed Retirement Age: Pension benefits are assumed to begin at each participant’s earliest unreduced retirement age, but not before the participant’s current age. The earliest unreduced retirement age is 63 for both plans.

| • |  | Discount Rate: The applicable discount rate as of December 31, 2023, was 5.2%.

| • |  | Mortality Table: The mortality table used as of December 31, 2021, is the Pri-2012 table (with contingent survivor mortality rates used after the original retiree’s death) projected forward generationally using Order 2 variation of scale MP-2021 with separate improvement tables for males and females. The mortality table used as of December 31, 2022, is the Pri-2012 table (with contingent survivor mortality rates used after the original retiree’s death) projected forward generationally using Order 2 variation of scale MP-2021 with separate improvement tables for males and females. There was no update to mortality.

2023 Nonqualified Deferred Compensation

Pursuant to the Company’s Management Incentive Plan, certain executives, including the NEOs, may defer annual incentive awards earned. Deferral elections are made by eligible executives in June of each year for the amounts to be earned for that year. An executive may defer all or a portion of his or her award pursuant to the provisions of the Management Incentive Plan. Deferred amounts are credited with earnings or losses based on the rate of return of mutual funds selected by the executive, which the executive may change as allowed under the Management Incentive Plan. Additional information regarding the Management Incentive Plan is included in the “Elements of Compensation” section of the Compensation Discussion and Analysis.

After an executive has elected to defer all or a portion of his or her annual incentive awards, no amounts can be paid until the executive has separated from service with the Company in accordance with the provisions of the Management Incentive Plan. At that time, benefits in the executive’s account shall be paid in a single sum or in substantially equal annual installments over three, five or ten years, as elected by the executive.

Executives may also elect to defer receipt of all or a portion of certain incentive compensation payments in accordance with the Stepan Company Performance Award Deferred Compensation Plan (effective January 1, 2008) (the “Performance Award Deferred Compensation Plan”). Information regarding deferrals under the Management Incentive Plan and Performance Award Deferred Compensation Plan is included in the table below.

Potential Payments upon Termination or Change in Control

The Company has no contracts, agreements, plans or other arrangements with its executives that provide for severance payments to NEOs in connection with a termination or change in control of the Company other than (1) benefits and payments disclosed in the 2023 Pension Benefits and 2023 Nonqualified Deferred Compensation tables above, (2) employee benefit plans and arrangements that do not discriminate in scope, terms or operation in favor of executive officers and that are generally available to all salaried employees and (3) the long-term incentive awards, which provide for accelerated vesting on termination or change in control as described below. The Company may, however, occasionally enter into separation agreements with its executives at the time of the executive’s termination of employment that provide for severance payments or benefits.

RSUs and SARs granted under the Company’s 2022 Equity Incentive Compensation Plan vest on a pro rata basis upon retirement and vest in full upon a termination of employment due to death or disability. Performance shares granted under the Company’s 2022 Equity Incentive Compensation Plan or under the Company’s 2011 Incentive Compensation Plan remain outstanding and eligible to vest based on actual performance on a pro rata basis in the case of retirement and in full in the case of death or disability. Under the 2022 Equity Incentive Compensation Plan, (a) if a replacement award is not granted, upon a change in control or (b) if a replacement award is granted, upon a termination by the Company without cause or a termination by the employee for good reason within two years following a change in control, outstanding RSUs and SARs vest in full and performance shares vest at the applicable target payout. The 2011 Incentive Compensation Plan does not require accelerated vesting of (i) RSUs or SARs in the event a termination of employment due to retirement, death or disability or in connection with a change in control or (ii) performance shares in connection with a change in control.

The table below quantifies the estimated benefit to NEOs other than Mr. Mergner in connection with a trigger occurring on the last business day of the Company’s 2023 fiscal year based on a share price of $94.55, the closing price of the Company’s Common Stock on December 29, 2023. Because Mr. Mergner retired from the Company on July 3, 2023, the following table does not show estimated benefits to Mr. Mergner in connection with a death, disability or change in control triggering event. The amounts shown for Mr. Mergner reflect the value of the outstanding RSUs and SARs the vesting of which accelerated upon his retirement. The amounts shown for Mr. Mergner also reflect the value of performance shares that remained outstanding at Mr. Mergner’s retirement and were eligible to vest after the end of the applicable performance periods. The closing price of the Company’s Common Stock on the date of Mr. Mergner’s retirement was $95.47. The performance share amounts for all NEOs assume performance at target levels for the applicable performance periods.

CEO Pay Ratio

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, we are providing the following information regarding the ratio of the annual total compensation of the Company’s median employee to the annual total compensation of Scott R. Behrens, the Company’s President and Chief Executive Officer. We consider the pay ratio specified below to be a reasonable estimate, calculated in a manner that is intended to be consistent with the requirements of Item 402(u) of Regulation S-K. For the fiscal year ended December 31, 2023:

| • |  | The median of the annual total compensation of all employees of the Company, except the President and Chief Executive Officer, was $72,284;

| • |  | The annual total compensation of the Company’s President and Chief Executive Officer was $4,123,893; and

| • |  | The ratio of the median of the annual total compensation of all Company employees, other than the Company’s President and Chief Executive Officer, to the annual total compensation of the Company’s President and Chief Executive Officer was approximately 1 to 57.

The Company chose December 31, 2023, as the date for determining the employee population used to identify the median employee. The Company identified the median employee using the base salaries of all employees globally, converting local currency non-U.S. base salaries into U.S. dollars using December 31, 2023, exchange rates. Permanent employees who joined in 2023 and permanent employees who were on leave during 2023 were assumed to have worked for the entire year. The Company used base salaries to identify the median employee because the Company does not widely distribute annual equity awards to employees and because this measure approximately reflects the total annual compensation of employees. The Company calculated the median employee’s and the President and Chief Executive Officer’s annual total compensation consistent with the disclosure requirements for the Summary Compensation Table. For purposes of this calculation, the median employee’s annual total compensation consisted of wages, premium pay (including overtime, holiday pay and shift differential), paid time off, non-equity incentive plan compensation, change in pension value and retirement plan contributions.

DIRECTOR COMPENSATION

Overview of Director Compensation Program

The Human Capital and Compensation Committee engaged Exequity as its independent consultant for Board compensation for 2023. Exequity advises the Committee on Board compensation matters such as the annual retainer fee, Board committee chair fees, and stock awards based on the Company’s peer group and market competitiveness. The Company uses a combination of cash and stock-based incentive compensation to attract and retain qualified candidates to serve on the Board. The Human Capital and Compensation Committee annually reviews the adequacy and competitiveness of the amount of the annual retainer fee, Board committee chair fees, and stock awards, and makes adjustments as it deems appropriate.

Directors’ Fees

For the fiscal year ended December 31, 2023, directors who were not also employees of the Company (“Non-Employee Directors”) were paid an annual retainer fee (“Annual Director Retainer Fee”) of $100,000. The non-executive Chairman of the Board was paid an additional annual fee of $225,000. The Lead Independent Director was paid an additional annual fee of $20,000, the Chair of the Audit Committee was paid an additional annual fee of $20,000, the Chair of the Human Capital and Compensation Committee was paid an additional annual fee of $20,000, the Chair of the Compliance Committee was paid an additional annual fee of $20,000, and the Chair of the Nominating and Corporate Governance Committee was paid an additional annual fee of $20,000. No fees or other compensation for service as a director were paid to directors who were also employees of the Company.

Directors Deferred Compensation Plan

A Non-Employee Director may defer receipt of his or her director compensation into one or more available investment options offered under the Stepan Company Directors Deferred Compensation Plan (as amended and restated as of January 1, 2012) (the “Directors Deferred Compensation Plan”). At the election of a Non-Employee Director, deferred payments generally may be made in shares of Common Stock or cash, depending upon the election made by the Non-Employee Director.

Stock Awards and Incentive Compensation Program for Non-Employee Directors

Pursuant to the 2022 Equity Incentive Compensation Plan and upon the terms and conditions as determined by the Human Capital and Compensation Committee, each Non-Employee Director serving as a director of the Company on the date of the annual meeting of stockholders each year is typically awarded an annual stock award (“Annual Stock Award”). At the Non-Employee Director’s election, the Annual Stock Award is either delivered at the time of the grant or deferred. For 2023, each Non-Employee Director serving as a director of the Company on April 25, 2023, received an Annual Stock Award of 1,325 shares of Common Stock. The number of shares was determined by dividing $125,000 by $94.32, the average of the opening and closing prices of Common Stock on the day of grant. The Annual Stock Award is vested upon grant and dividend equivalents are credited on deferred Annual Stock Awards. The Non-Employee Directors did not receive any other stock option or stock grants in 2023.

In addition to the Annual Stock Awards, under the 2022 Equity Incentive Compensation Plan, the Human Capital and Compensation Committee is permitted to make grants of stock options or additional stock awards to Non-Employee Directors at the times and in the amounts and subject to such other terms and conditions as determined by the Human Capital and Compensation Committee in its sole discretion. The Human Capital and Compensation Committee granted no such awards in 2023.

50

Non-Employee Directors’ Stock Ownership Policy

The Company maintains a Non-Employee Directors’ Stock Ownership Policy that requires each Non-Employee Director to own a minimum amount of Common Stock equivalent in value to five times the current Annual Director Retainer Fee. During the first thirty-six months of service eligible directors are encouraged, but not required, to progress toward compliance in twenty percent increments up to sixty percent. After thirty-six months of service eligible Directors are required to demonstrate progress toward the stock ownership requirement by complying with eighty percent of the required ownership level after year four and one hundred percent of the required ownership level after five years. The following shares count towards the stock ownership requirements: (i) shares owned directly or by any immediate family member, (ii) shares owned indirectly as trustee or custodian for the benefit of children and family members, and (iii) shares held in the Non-Employee Director’s deferred compensation plan accounts.

Each Non-Employee Director has five years from the date of his or her initial election or appointment as a director to achieve compliance with these stock ownership requirements. Compliance with the stock ownership policy for all Non-Employee Directors is reviewed on an annual basis. Currently, all Non-Employee Directors are in compliance with stock ownership requirements; Non-Employee Directors appointed over five years ago are in full compliance and Non-Employee Directors appointed within the last five years have made the requisite progress towards full compliance. Any Non-Employee Director who is not in compliance with the required stock ownership level must retain 100% of his or her vested shares (after tax) until compliance is achieved.

Hedging and Trading Restrictions

The Company’s Insider Trading Policy also applies to Non-Employee Directors. This policy, among other things, prohibits Non-Employee Directors from hedging the economic risk of their ownership in the Company’s Common Stock, short-selling the Company’s securities, or trading in the Company’s securities outside of trading window periods or without pre-clearance.

PROPOSAL NO. 2: ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION

As required under the Dodd-Frank Act and Section 14A of the Exchange Act, the Company is including in this proxy statement a non-binding advisory vote to approve the compensation of the Company’s NEOs. Each year, the Company asks for the stockholders to indicate their approval of the compensation paid to the Company’s NEOs. The compensation paid in 2023 is described in this proxy statement in the Compensation Discussion and Analysis as well as the compensation tables and related narratives. Those sections describe the Company’s NEO compensation programs and the rationale behind the decisions made by the Human Capital and Compensation Committee.

This Say-on-Pay vote provides stockholders with the opportunity to express their views about the compensation paid to the Company’s NEOs as described in this proxy statement. A stockholder may vote “FOR” or “AGAINST” the resolution or may “ABSTAIN” from voting on the resolution. Approval of this proposal requires the affirmative vote of a majority of the voting power present in person or by proxy and entitled to vote on this matter. The result of the Say-on-Pay vote will not be binding on the Company or the Board of Directors. However, the Board of Directors values the views of the Company’s stockholders and will review the voting results and take them into consideration when making future decisions regarding compensation of the Company’s NEOs. At the 2023 Annual Meeting of Stockholders, the Company’s executive compensation was approved by 98% of the votes cast at the meeting on the proposal. The Board of Directors and the Human Capital and Compensation Committee considered these voting results when they made decisions regarding the compensation of the Company’s NEOs. Unless the Board of Directors modifies its determination on the frequency of future Say-on-Pay votes, the next such advisory vote will be held at the 2025 Annual Meeting of Stockholders. The Company anticipates next seeking an advisory vote on the frequency of Say-on-Pay votes at its 2029 Annual Meeting of Stockholders.

The Board of Directors believes that the Company’s executive compensation program is appropriately designed and is operating effectively to compensate the Company’s NEOs based on achievement of annual and long-term performance goals that are aligned with enhanced stockholder value. As described in the Compensation Discussion and Analysis, the Company’s objectives for its compensation program, including the compensation program for the NEOs, are as follows:

| • |  | motivate employees to achieve and maintain a high level of performance, and drive results that will help the Company achieve its goals;

| • |  | align the interests of our employees with the interests of our stockholders;

| • |  | provide for market-competitive levels of compensation; and

| • |  | attract and retain employees of outstanding ability.

In support of these objectives, the Human Capital and Compensation Committee follows these guiding principles for setting and awarding NEO executive compensation:

| • |  | Pay for Performance. The basic premise of the Company’s NEO compensation philosophy is to pay for performance. The Company’s intention is to foster a performance-driven culture with competitive total compensation as a key driver for executive employees. Compensation levels commensurate with Company performance align the interests of the Company’s NEOs with the interests of the Company’s stockholders. For 2023, incentive pay was directly connected to Company and individual performance. See the “Short-Term Incentive Compensation” and the “Long-Term Incentive Compensation” sections in the Compensation Discussion and Analysis of this proxy statement for a discussion on the connection between Company performance and compensation levels for each incentive compensation component.

52

| • |  | Competitive Compensation. Base salaries were surveyed and determined to be consistent with similar positions in similar industries. The Company believes that the level of 2023 executive compensation offered as part of its total reward components was necessary to attract and retain talented NEOs. See the “Compensation Peer Group and Survey Data” section in the Compensation Discussion and Analysis of this proxy statement for a description of the process used for comparing the Company’s compensation programs with those of the Company’s peers.

| • |  | Equity-Based Compensation Aligns the NEOs with the Interests of Stockholders. The Human Capital and Compensation Committee has designed the compensation for NEOs to depend on the achievement of objective performance goals that drive and are aligned with stockholder value. Information related to the amount of NEO compensation that is paid as RSUs, SARs and performance shares is described in the “Long-Term Incentive Compensation” section in the Compensation Discussion and Analysis of this proxy statement.

| • |  | Stock Ownership Policy. The Company maintains a stock ownership policy because it believes that ownership of Company stock by key executives is desirable in order to focus both short-term and long-term decision-making on the best interests of the Company and its stockholders. See the “Stock Ownership Policy” section in the Compensation Discussion and Analysis of this proxy statement for a more detailed description of this policy.

| • |  | Hedging and Trading Restrictions. The Company has an Insider Trading Policy that prohibits directors, officers and employees from hedging the economic risk of their ownership in the Company’s Common Stock and prohibits short-selling of the Company’s securities. In addition, the Insider Trading Policy prohibits directors, officers and certain other employees from trading in the Company’s securities outside of trading window periods or without pre-clearance.

| • |  | Reasonable and Limited Perquisites and Other Benefits. The limited amount of benefits and perquisites offered to the NEOs is common with companies in our industry and is reasonable in both nature and amount.

| • |  | No Standing Severance/Change-in-Control Agreements. None of the NEOs have any arrangement that provides for cash severance payments. Additionally, none of the NEOs are entitled to payment of any benefits upon a change-in-control (other than potential equity award vesting).

As summarized above, the compensation earned by the Company’s NEOs for 2023 was generally aligned with both the Company’s pay for performance philosophy and 2023 Company performance. You should read the Compensation Discussion and Analysis and the compensation tables in this proxy statement in determining whether to approve this proposal. For the reasons discussed above, the Board of Directors recommends that the stockholders vote to approve the following resolution:

RESOLVED, that the compensation paid to the Company’s named executive officers as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby APPROVED.

PROPOSAL: The Board of Directors recommends that the stockholders vote, on an advisory basis, FOR the above resolution approving the compensation of the Company’s NEOs.

PROPOSAL NO. 3: RATIFY THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS THE COMPANY’S INDEPENDENT PUBLIC ACCOUNTING FIRM FOR 2024

The Audit Committee has selected Deloitte as the independent registered public accounting firm for the Company for 2024. Stockholder ratification of the selection of Deloitte as the Company’s independent registered public accounting firm for 2024 is not required by our By-laws or otherwise. However, the Board of Directors is submitting the selection of Deloitte for stockholder ratification as a matter of good corporate governance practice. The Audit Committee will take the results of the stockholder vote regarding Deloitte’s appointment into consideration in future deliberations. Even if the selection is ratified, the Audit Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time if it determines that such a change would be in the best interests of the Company and its stockholders.

A representative of Deloitte is expected to be present at the Annual Meeting with the opportunity to make a statement, and to be available to respond to appropriate questions.

PROPOSAL: Upon the recommendation of the Audit Committee, the Board of Directors recommends that the stockholders vote FOR the ratification of the appointment of Deloitte as the independent registered public accounting firm for the Company and its subsidiaries for fiscal year 2024.

Pre-Approval Policy

The Audit Committee is responsible for appointing, setting compensation for and overseeing the work of the independent registered public accounting firm. The Audit Committee has established a policy requiring the pre-approval of all audit, audit-related, and permissible non-audit services provided by the independent registered public accounting firm. The policy provides guidance as to the specific services that the independent registered public accounting firm may perform for the Company. The policy requires that a description of the services expected to be performed by the independent registered public accounting firm, together with an estimate of fees, be provided to the Audit Committee for approval on an annual basis. The scope of these services is carefully considered by the Audit Committee to ensure such services are consistent with applicable rules on auditor independence.

Any requests for audit, audit-related, and non-audit services not previously authorized must be submitted to the Audit Committee for specific pre-approval. Normally, pre-approval is provided at regularly scheduled Audit Committee meetings. However, the policy delegates to the Chair or another designated member of the Audit Committee the authority to grant specific pre-approval between meetings provided that the Chair or designated member reports any pre-approval decision to the Audit Committee at its next regularly scheduled meeting.

All of the services related to the Audit Fees, Audit-Related Fees, Tax Fees and All Other Fees described above were approved by the Audit Committee in accordance with its pre-approval requirements.

In addition to satisfying the requirements under the Company’s By-laws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act (including a statement that such stockholder intends to solicit the holders of shares representing at least 67% of the voting power of the Company’s shares entitled to vote on the election of directors in support of director nominees other than the Company’s nominees), which notice must be postmarked or transmitted electronically to the Company at its headquarters no later than 60 calendar days prior to the anniversary date of the 2024 Annual Meeting (for the 2025 Annual Meeting of Stockholders, no later than March 3, 2025 (the first business day following March 1, 2025)). However, if the date of the 2025 Annual Meeting is changed by more than 30 calendar days from such anniversary date, then notice must be provided by the later of 60 calendar days prior to the date of the 2025 Annual Meeting or the 10th calendar day following the day on which public announcement of the date of the 2025 Annual Meeting is first made.

Appendix A

Discussion and Reconciliation of GAAP and Non-GAAP Financial Measures

The Company believes that certain non-GAAP measures, when presented in conjunction with comparable GAAP measures, help investors’ ability to understand underlying trends in the Company’s operating performance and provide useful information to both management and investors by excluding items that may not be indicative of the Company’s core operating results. Internally, the Company uses certain non-GAAP information as an indicator of business performance and evaluates management’s effectiveness with specific reference to these indicators. In addition, the Human Capital and Compensation Committee of the Company’s Board of Directors uses certain non-GAAP measures, including Corporate Net Income and ROIC, as targets under the Company’s short-term and long-term incentive compensation programs. These measures should be considered in addition to, not a substitute for or superior to, measures of financial performance prepared in accordance with GAAP. In addition, other companies may calculate adjusted net income and such other metrics differently than the Company does, limiting their usefulness as comparative measures.

Reconciliation of GAAP Net Income to Adjusted Net Income

The following table reconciles the Company’s GAAP net income to adjusted net income. Adjusted net income is used as an incentive compensation performance metric, as discussed below. The cumulative tax effect of the adjustment items was calculated using the statutory tax rates for the jurisdictions in which the transaction occurred.

|  | Twelve Months Ended December 31, |
(In millions, except per share amounts) |  | 2023 |  |  | EPS |  |  | 2022 |  |  | EPS |
Net Income Attributable to the Company as Reported |  | $ | 40.2 |  |  | $ | 1.75 |  |  | $ | 147.2 |  |  | $ | 6.38 |
Deferred Compensation (Income) Expense |  |  | (0.7 | ) |  |  | (0.03 | ) |  |  | (3.1 | ) |  |  | (0.14) |
Business Restructuring and Asset Impairment Expense |  |  | 12.0 |  |  |  | 0.52 |  |  |  | 0.3 |  |  |  | 0.01 |
Goodwill and Other Intangibles Impairment Expense |  |  | 2.0 |  |  |  | 0.09 |  |  |  | — |  |  |  | — |
Cash-Settled SARs (Income) Expense |  |  | (0.1 | ) |  |  | — |  |  |  | (0.4 | ) |  |  | (0.01) |
Environmental Remediation Expense |  |  | 1.0 |  |  |  | 0.04 |  |  |  | 11.5 |  |  |  | 0.50 |
Cumulative Tax Effect on Above Adjustment Items |  |  | (3.7 | ) |  |  | (0.16 | ) |  |  | (2.0 | ) |  |  | (0.09) |
Adjusted Net Income |  | $ | 50.7 |  |  | $ | 2.21 |  |  | $ | 153.5 |  |  | $ | 6.65 |

Use of Non-GAAP Corporate Net Income for Compensation Purposes

The Company used adjusted net income (calculated in accordance with the table set forth above) as the 2023 Corporate Net Income incentive compensation performance metric.

Definition of Non-GAAP Return on Invested Capital (ROIC)

To calculate the Return on Invested Capital incentive compensation performance metric, the Company divides net operating profit after taxes (“NOPAT”) by invested capital. The Company calculates NOPAT by adding the Corporate Net Income Adjustments to pre-tax income and subtracting the effect of income taxes. The Company calculates invested capital by adding the 12-month average trade accounts receivable balance to the 12-month average FIFO inventory balance and subtracting the 12-month average trade accounts payable balance plus the January 1 net property, plant and equipment and other non-current assets balance.
