(1) Based on New York Stock Exchange rules, if your shares are held through a broker, bank or other nominee, they do not have discretion to vote on your behalf on non-routine matters if you do not provide voting instructions.

(2) Because this proposal has three possible substantive responses (1 year, 2 years or 3 years), if none of the frequency alternatives receives the vote of the holders of a majority of the shares present, then we will consider stockholders to have approved the frequency selected by holders of a plurality of the shares present.

#### 2022 MILESTONES AND PERFORMANCE HIGHLIGHTS
In 2022, we continued to strengthen the Company by making strategic investments and shareholder-friendly governance enhancements while also returning a substantial amount of capital to our stockholders:

We invested in our core business, while also stream-lining operations and our shared service platform:

• Completed our $180 million splitter investment in Geismar, Louisiana, enabling production of more high value, differentiated grades of methylene diphenyl diisocyanate (MDI) for key customer applications.

• Progressed announced expansions of the product portfolio of our Performance Products business, including catalysts for polyurethane insulation, carbonates for lithium-ion electric vehicle batteries, and high value performance amines used in the semiconductor industry.

• Announced and closed in February 2023 the divestment of our Textile Effects business to Archroma, a portfolio company of SK Capital, for approximately $593 million and pension liabilities, further simplifying our overall portfolio.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• Expanded our global cost optimization and synergy programs (the "Optimization Program") to target a total annualized run-rate of $280 million in savings by the end of 2023, of which we have already achieved an annualized run-rate of approximately $190 million.

We made meaningful enhancements to our governance structures and advanced our sustainability achievements:

• Refreshed Board and committee leadership with the appointment of Cynthia Egan as Non-Executive Vice Chair, Lead Independent Director, and Chair of the Board's Nominating and Corporate Governance Committee, Sonia Dulá as Chair of the Compensation Committee, and Jeanne McGovern as Chair of the Audit Committee

• Added broad-based, sitting or just-retired chief executive and chief financial officer experience in highly relevant industries or strategic markets to the Board by appointing Curtis Espeland, former CFO of Eastman Chemical, José Muñoz, Chief Operating Officer of Hyundai, and David Sewell, CEO of Westrock.

• Published our 2021 corporate sustainability report titled "Brightening the Horizon: Enabling Sustainability," which featured Task Force on Climate-related Financial Disclosures (TCFD) for the first time, further improvements in the quality of our other sustainability-related disclosures, and a Limited assurance by a third party auditor for our operational greenhouse gas (GHG) emissions (Scope 1 and Scope 2) and water consumption.

• Announced a new $1.2 billion senior unsecured, sustainability-linked revolving credit facility.

• Awarded approximately $125 million by a New Orleans jury against Praxair/Linde after a long-running court battle.

We enhanced shareholder return by leveraging our strong balance and cash flow to increase our dividend and repurchase more than a billion dollars-worth of our stock:

• Increased our quarterly dividend by 13% in February 2022 and distributed approximately $171 million in dividends in 2022.

• Repurchased approximately 32 million shares for approximately $1 billion over the course of the 2022 year.

• Announced a doubling of our share repurchase program in March 2022 from $1 billion to $2 billion with approximately $900 million remaining of the authorization as of January 2023.

#### BOARD DIVERSITY
Board composition and director succession is a thoughtful, ongoing process at Huntsman. The Board identifies and evaluates desired director attributes, professional and life experiences, and skill sets in light of the Company's strategic direction and evolving needs. As part of the Board's multi-year director succession and refreshment process that began during 2018, we have added eight new independent directors (including four women, two ethnically-diverse directors and, as a retired Vice Admiral of the U.S. Navy, one veteran) to the Board.

Our Board is composed of highly-qualified, diverse leaders from highly relevant industries and markets possessing key expertise, lived experience, and skills, and represents an effective mix of deep Company knowledge and fresh perspective. The following graphic illustrates the diverse and well-rounded range of attributes, viewpoints and experiences of our 10 director nominees.

See Appendix B for additional information regarding adjusted EBITDA margin and a reconciliation to net income.

(2) Throughout this Proxy Statement, we refer to free cash flow, which is a non-GAAP financial measure. For purposes of compensation determinations, free cash flow is calculated as operating cash from continuing operations less capital expenditures from continuing operations less net cash proceeds from the Albemarle Settlement. See Appendix B for additional information regarding free cash flow and a reconciliation to operating cash from continuing operations.

#### Our Response to Stockholder Feedback
We engage in a continuous dialogue with our stockholders and have made numerous changes over the years in response to stockholder feedback.

In response to feedback, the Compensation Committee has consistently implemented improvements that further align incentive payouts with the creation of stockholder value. Specifically, the Compensation Committee has gradually increased the weighting of performance share units from 30% of equity-based incentives in 2019, to 40% in 2020, 50% in 2021 and 70% in 2022.

HUNTSMAN CORPORATION: PROXY STATEMENT SUMMARY <br>

In December 2021, as a part of our ongoing review of our executive compensation program and driven by the desire to better align pay outcomes across the Company with performance against preset goals, the Board authorized and is overseeing a multi-year compensation plan that covers all corporate officers and vice presidents, including NEOs, in December 2021. The vesting of these incentives, starting in 2022, is conditioned upon the achievement of the targets presented at our Company's Investor Day in November 2021 (and described below) with the specific intention of aligning the interests of our officers and other senior level employees with those of all long-term stockholders.

At our 2022 annual meeting, the say-on-pay proposal received the support of approximately 85% of the stockholders casting their votes. Both looking forward and back, the Compensation Committee carefully considers the say-on-pay results and the stockholder feedback we received in determining executive compensation.

#### PREFERRED FREQUENCY OF EXECUTIVE COMPENSATION ADVISORY VOTES (PROPOSAL 3)
Reflecting the value of stockholder feedback, the Board believes that say-on-pay votes should be conducted every year to ensure we get your direct and timely input on our executive compensation program. While our executive compensation programs are designed to promote a long-term connection between pay and performance, the Board recognizes that executive compensation disclosures are made annually and holding an annual advisory vote on executive compensation provides regular and clear feedback on our compensation disclosures on the same cycle.

We ask you to vote for "**1 YEAR**" for the preferred frequency, on a non-binding advisory basis, of advisory votes on the compensation of our named executive officers using the enclosed proxy card.

#### INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (PROPOSAL 4)
We ask you to vote "**FOR**" the ratification of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2023 using the enclosed proxy card.

#### AMENDMENT TO AMENDED AND RESTATED CERTIFICATION OF INCORPORATION (PROPOSAL 5)
The State of Delaware recently enacted legislation that enables Delaware companies to limit certain types of liability of certain of their officers in limited circumstances. As a Delaware corporation, we are proposing to amend and restate the Company's Amended and Restated Certificate of Incorporation (the "Certificate of Incorporation") to, among other things, provide for exculpation of certain of the Company's officers from certain liability in specific and limited circumstances as permitted by Delaware law.

We ask you to vote "**FOR**" the Second Amended and Restated Certificate of Incorporation to reflect changes in Delaware law regarding officer exculpation using the enclosed proxy card.

#### STOCKHOLDER PROPOSAL TO REQUIRE STOCKHOLDER RATIFICATION OF EXECUTIVE TERMINATION PAYMENTS (PROPOSAL 6)
We ask you to vote "**AGAINST**" the stockholder proposal regarding shareholder ratification of excessive termination pay using the enclosed proxy card. Please see page 84 for our Board's Statement in Opposition.

In addition to solicitation by mail, certain of our directors, officers and employees may, without extra compensation, solicit proxies by telephone, facsimile, electronic means and personal interview. We have retained Innisfree M&A Incorporated to help us distribute and solicit proxies and agreed to pay them $17,500 and reimburse them for out-of-pocket expenses for these services. We will also make arrangements with brokerage houses, custodians, nominees, and other fiduciaries to send proxy materials to their principals, and we will reimburse them for postage and clerical expenses.

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

9. HOW MANY VOTES ARE REQUIRED TO HOLD THE ANNUAL MEETING?

The required quorum for the transaction of business at the Annual Meeting is a majority of all outstanding shares of our common stock entitled to vote in the election of directors at the Annual Meeting, represented in person or by proxy. Consequently, the presence in person or by proxy of the holders of at least 91,836,570 shares of our common stock is required to establish a quorum at the Annual Meeting. Shares that are voted with respect to a particular matter are treated as being present at the Annual Meeting for purposes of establishing a quorum.

10. WHAT IS THE DIFFERENCE BETWEEN A STOCKHOLDER OF RECORD AND A STOCKHOLDER WHO HOLDS STOCK IN STREET NAME?

Most stockholders hold their shares through a broker, bank or other nominee (i.e., in "street name") rather than directly in their own name. As summarized below, there are some distinctions between shares held of record and those held in street name.

• **Stockholders of Record.** If your shares are registered directly in your name with our transfer agent, you are considered the "stockholder of record" with respect to those shares.

• **Street Name Stockholders.** If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner of shares held in "street name" with respect to those shares. If you are a street name stockholder, you will be forwarded proxy materials by your broker, bank, or other nominee, which is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to instruct your broker, bank, or other nominee how to vote. Your broker, bank, or other nominee has been provided with a voting instruction form for you to use in directing the broker, bank, or other nominee how to vote your shares. If you fail to provide sufficient instructions to your broker, bank, or other nominee, they may be prohibited from voting your shares. See "If I am a street name stockholder, will my shares be voted if I do not provide instructions?" as described in Question 13 below.

11. WHAT DIFFERENT METHODS CAN I USE TO VOTE?

**Stockholders of Record:** Stockholders of record may (1) vote their shares in person at the Annual Meeting by completing a ballot; or (2) submit a proxy to have their shares voted by one of the following methods:

• *By Internet.* You may submit a proxy electronically on the Internet by following the instructions provided on the enclosed proxy card. Please have your proxy card in hand when you log onto the website. Internet voting facilities will be available 24 hours a day.

• *By Telephone.* You may submit a proxy by telephone (from U.S. and Canada only) using the toll-free number listed on the enclosed proxy card. Please have your proxy card in hand when you call. Telephone voting facilities will be available 24 hours a day.

• *By Mail.* If you received a paper copy of the proxy materials by mail, you may indicate your vote by completing, signing and dating your proxy card and returning it in the enclosed postage-paid reply envelope.

**Street Name Stockholders:** Street name stockholders may generally vote their shares or submit a proxy to have their shares voted by one of the following methods:

• *By the Methods Listed on the Voting Instruction Form.* Please refer to the voting instruction form or other information forwarded by your bank, broker or other nominee to determine whether you may submit a proxy by telephone or on the Internet, following the instructions provided by the record holder.

• *Electronically at the Annual Meeting.* You may vote electronically at the Annual Meeting. To participate in the virtual Annual Meeting, you will need the 16-digit control number included in your proxy card, voting instruction form.

• If your shares are held in "street name" and you wish to revoke a proxy, you should contact your bank, broker or nominee and follow its procedures for changing your voting instructions.

If you hold shares in **BOTH** street name and as a stockholder of record, **YOU MUST VOTE SEPARATELY** for each set of shares.

12. WHAT IF I AM A STOCKHOLDER OF RECORD AND I DON'T SPECIFY A CHOICE FOR A MATTER WHEN RETURNING MY PROXY?

A validly executed proxy that is properly completed and submitted will be voted at the Annual Meeting in accordance with the instructions on the proxy. If you properly complete and submit a validly executed proxy card but do not indicate how your shares should be voted and do not revoke your proxy, your shares will be voted as follows:

• **FOR** the election of all 10 of the director nominees recommended by the Board;

[**TABLE OF CONTENTS**](#TOC)

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• **FOR** approval, on a non-binding advisory basis, of the compensation of our NEOs;

• **1 YEAR** for the preferred frequency, on a non-binding advisory basis, of advisory votes on the compensation of our NEOs;

• **FOR** the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2023;

• **FOR** the approval of the Second Amended and Restated Certificate of Incorporation to, among other things, reflect changes in Delaware law regarding officer exculpation; and

• **AGAINST** the stockholder proposal regarding shareholder ratification of excessive termination pay.

If any other business properly comes before the stockholders for a vote at the Annual Meeting, your shares will be voted at the discretion of the holders of the proxy on such matters to the extent authorized by Rule 14a-4(c). The Board knows of no matters other than those previously described to be presented for consideration at the Annual Meeting.

Even if you plan to attend the Annual Meeting, we recommend you also submit your proxy so that your vote will count if you are unable to attend the meeting. Submitting your proxy via internet, telephone or mail does not affect your ability to vote in person at the Annual Meeting.

13. IF I AM A STREET NAME STOCKHOLDER, WILL MY SHARES BE VOTED IF I DO NOT PROVIDE INSTRUCTIONS?

In some cases, your shares may be voted if they are held in the name of a brokerage firm even if you do not provide the brokerage firm with voting instructions. Specifically, brokerage firms have the authority under New York Stock Exchange ("NYSE") rules to cast votes on certain "routine" matters if they do not receive instructions from the beneficial holder. For example, ratification of the appointment of the independent registered public accounting firm (Proposal 4) is typically considered a routine matter for which a brokerage firm may vote shares for which it has not received voting instructions. This is called a "broker discretionary vote." When a proposal is not a routine matter and a brokerage firm has not received voting instructions from the beneficial owner of the shares with respect to that proposal, the brokerage firm cannot vote the shares on that proposal. This is called a "broker non-vote." Proposals 1, 2, 3, 5 and 6 are not considered routine matters. Therefore, if you do not provide voting instructions to your broker with respect to these matters, it will result in a broker non-vote with respect to such proposals. Broker non-votes, if any, will have no effect on the outcome of Proposals 1, 2, 3, and 6 and will have the same effect as a vote "against" Proposal 5.

14. WHAT VOTES ARE NEEDED FOR EACH PROPOSAL TO PASS AND IS BROKER DISCRETIONARY VOTING ALLOWED?

---

| | | |
|:---|:---|:---|
| **Proposal**  | **Vote Required**  | **Broker Discretionary <br> Vote Allowed** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (1) <br>Election of 10 director nominees <br>| Majority of votes cast  | No  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (2) <br>A non-binding advisory vote to approve the compensation of our NEOs <br>| Majority of shares present (in person or represented by proxy) and entitled to vote on the matter  | No |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (3) <br>A non-binding advisory vote to approve the preferred frequency of votes on the compensation of our NEOs <br>| Majority of shares present (in person or represented by proxy) and entitled to vote on the matter<sup>(1)</sup>  | No |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (4) <br>Ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2023 <br>| Majority of shares present (in person or represented by proxy) and entitled to vote on the matter  | Yes |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (5) <br>Approval of the Second Amended and Restated Certificate of Incorporation <br>| Majority of shares issued and outstanding | No |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (6) <br>If properly presented at the meeting, a stockholder proposal regarding shareholder ratification of excessive termination pay <br>| Majority of shares present (in person or represented by proxy) and entitled to vote on the matter  | No |

---

(1) Because this proposal has three possible substantive responses (1 year, 2 years or 3 years), if none of the frequency alternatives receives the vote of the holders of a majority of the shares present, then we will consider stockholders to have approved the frequency selected by holders of a plurality of the shares present.

15. WHAT HAPPENS IF ADDITIONAL PROPOSALS ARE PRESENTED AT THE ANNUAL MEETING?

If you grant a proxy, the persons named as proxy holders will have discretion to vote your shares on any additional matters properly presented for a vote at the Annual Meeting to the extent authorized by Rule 14a-4(c). Under the provisions of our Bylaws and Rule 14a-8 promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), the deadline for notifying us of any additional proposals to be presented at the Annual Meeting has passed and, accordingly, stockholders may not present proposals at the Annual Meeting.

16. CAN I CHANGE MY VOTE AFTER SUBMITTING MY PROXY?

If you are a stockholder of record, you may revoke a previously submitted proxy at any time before the polls close at the Annual Meeting by:

• voting again by telephone or through the Internet;

• requesting, completing and mailing in a new paper proxy card;

• giving written notice of revocation to our Corporate Secretary, which must be received before the Annual Meeting, by mail to Corporate Secretary, 10003 Woodloch Forest Drive, The Woodlands, Texas 77380 or to *CorporateSecretary@huntsman.com*; or

• attending the Annual Meeting and voting in person (merely attending the Annual Meeting will not revoke a prior submitted proxy).

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

DIRECTOR COMPENSATION

Our Corporate Governance Guidelines provide for compensation for our non-employee directors' services in recognition of their time and skills. Directors who are also our officers or employees do not receive additional compensation for serving on the Board. Annual compensation for our non-employee directors is composed of cash and equity-based compensation. Cash compensation paid to our non-employee directors consists of an annual retainer and supplemental retainers for the chairs and members of Board committees. Equity-based compensation for 2022 consisted of awards granted under the Huntsman Corporation 2016 Huntsman Stock Incentive Plan (the "2016 Stock Incentive Plan") in the form of fully-vested stock awards or deferred stock units, at the election of each director.

Maintaining a market-based compensation program for our non-employee directors enables our Company to attract qualified members to serve on the Board. With the assistance of Meridian Compensation Partners, LLC ("Meridian"), the Compensation Committee's independent compensation consultant, the Compensation Committee periodically reviews our non-employee director compensation practices and compares them to the practices of our peers as well as against the practices of public company boards generally to ensure they are aligned with market practices.

We also offer non-employee directors the opportunity to participate in the Huntsman Outside Directors Elective Deferral Plan. This is an unfunded nonqualified deferred compensation plan established primarily for the purpose of providing our non-employee directors with the ability to defer the receipt of director fees. For 2022, none of our non-employee directors elected to participate in this plan. The investment choices available under this plan are identical to the investment choices available under our 401(k) plan. Benefits under the plan are payable in cash distributable either in a lump sum or in installments beginning 30 days after the director ceases to be a member of our Board.

Members of the Board may also participate in the Huntsman Director Matching Gift Program. Designed to demonstrate our commitment to worthy causes and attract talented directors, our Company will match charitable contributions made in cash up to a maximum of $10,000 per director per year for organizations located in the United States that are tax exempt pursuant to Section 501(c)(3) of the Internal Revenue Code.

The Compensation Committee believes that our total director compensation package is competitive with market practices, as well as fair and appropriate in light of the responsibilities and obligations of our non-employee directors. Details of our non-employee director compensation program are below.

#### DIRECTOR COMPENSATION TABLE
The total 2022 compensation for our non-employee directors is shown in the following table:

The Board identifies and evaluates desired director attributes, professional and life experiences, and skill sets in light of the Company's strategic direction and evolving needs. As part of our Board's multi-year director succession and refreshment process that began during 2018, we have added eight new independent directors (including four women, two ethnically-diverse directors and, as a retired Vice Admiral of the U.S. Navy, one veteran) to the Board.

Our Board in composed of highly-qualified, diverse leaders from highly relevant industries and markets possessing key expertise, lived experience, and skills, and represents of an effective mix of deep Company knowledge and fresh perspective. The following graphic illustrates the diverse and well-rounded range of attributes, viewpoints and experiences of our 10 director nominees.

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

![[MISSING IMAGE: pc_boarreppn.jpg]](pc_boarreppn.jpg)

BOARD GOVERNANCE

The Board and its committees meet throughout the year on a set schedule and may also hold special meetings and act by written consents from time to time as appropriate. During 2022, the Board met 14 times, and the non-management directors met in executive session five times. During 2022, each director attended at least 75% of the aggregate of:

• the total number of meetings of the Board; and

• the total number of meetings held by all Board committees on which such person served.

BOARD LEADERSHIP STRUCTURE AND EXECUTIVE SESSIONS OF THE BOARD

According to our Bylaws, the Chairman of the Board is elected by all the directors on the Board to preside at all meetings of the Board and stockholders. The Chairman is also required to make reports to the Board and the stockholders and to ensure that all orders and resolutions of the Board and any of its committees are put into effect. In accordance with our Corporate Governance Guidelines, the Chairman of the Board is also responsible for establishing the agenda for each Board meeting. At the beginning of the year, the Chairman establishes a schedule of agenda subjects to be discussed during the year (to the degree this can be foreseen). Each Board member is also free to suggest the inclusion of additional items on the agenda and to raise subjects at any Board meeting that are not on the agenda for that meeting. Peter R. Huntsman serves as our Chairman of the Board.

In accordance with our Corporate Governance Guidelines, the Board has no policy with respect to the separation of the offices of Chairman of the Board and Chief Executive Officer. Our Bylaws expressly allow our Chairman to serve as President or Chief Executive Officer if so elected by the Board. Currently, the Board believes that the interests of the Company and its stockholders are best served through a leadership model that combines the roles of Chairman of the Board and Chief Executive Officer. The Board further believes that this issue should be reconsidered periodically as part of the succession planning process, and that it is in the best interests of our stockholders for the Board to consider issue each time it appoints a new Chief Executive Officer. Based on these principles, the Board may determine that it is appropriate in the future to separate the roles of Chairman of the Board and Chief Executive Officer.

26 HUNTSMAN 2023 PROXY

[**TABLE OF CONTENTS**](#TOC)

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

Our Bylaws also allow the Board to elect a Vice Chair to preside at Board and stockholder meetings and to perform such other duties as may be delegated by the Board in the Chairman's absence. The Board believes that Ms. Egan, elected and acting as Vice Chair, adds incremental and valuable leadership at the Board level Additionally, as the Board's Lead Independent Director, Ms. Egan efficiently communicates with management on issues relevant to all the independent directors and provides leadership on matters where there exists even a potential for management to have a conflict of interest. In accordance with our Corporate Governance Guidelines, non-management directors meet in executive session without management at each regularly scheduled Board meeting, or more frequently as needed at the call of one or more of our non-management directors. Ms. Egan, as Non-Executive Vice Chair of the Board and Lead Independent Director, chairs these sessions.

We believe that the appropriate Board leadership structure for our Company varies depending on the circumstances facing the Board and our Company at any given time. For example, we revised the Board's governance structure in the past to address specific needs, such as the election of Ms. Egan as Non-Executive Vice Chair of the Board and Lead Independent Director in January 2022, the creation and chartering of the Sustainability Committee in February 2021, and the election of Peter R. Huntsman as Chairman of the Board, in addition to his role as President and Chief Executive Officer, in December 2017, having determined that this was the most efficient manner to facilitate effective communication between management and the Board, provide strong and consistent leadership, and speak with a unified voice for the Company. The Board believes that our current leadership structure efficiently addresses our Company's present needs and allows the Board to fulfill its fiduciary role in exercising effective, independent oversight of our management on behalf of our stockholders. The Board further believes that we have in place effective structures, processes and arrangements to ensure that the work of the Board is completed in a manner that maintains the highest standards of corporate governance, independence and leadership, and facilitates the clear and continued accountability of management.

BOARD INDEPENDENCE

Investors must have confidence that the individual Board members we have identified as independent directors do not have relationships of any sort that impair or compromise their independence. Under NYSE corporate governance rules, the Board must have a majority of independent directors. For a director to qualify as independent, the Board must affirmatively determine that the director has no material relationship with our Company either directly or as a partner, stockholder or officer of an organization that has some relationship with our Company. To assist in making independence determinations, the Board has adopted criteria that can be found on our website at *www.huntsman.com*. Under these criteria, a director is not independent if:

• The director is, or has been within the last three years, an employee of our Company or an employee of any of our subsidiaries, or an immediate family member is, or has been within the last three years, an executive officer of our Company.

• The director has received, or has an immediate family member who has received, during any twelve-month period within the last three years, more than $120,000 in direct compensation from us (other than director and committee fees and pension or other forms of deferred compensation for prior service, which compensation is not contingent upon continued service). Compensation received by an immediate family member for service as an employee (other than an executive officer) of ours is not considered for purposes of this standard.

• The (1) director or an immediate family member is a current partner of a firm that is our internal or external auditor; (2) director is a current employee of such a firm; (3) director has an immediate family member who is a current employee of such a firm and who personally works on our Company's audit; or (4) director or an immediate family member was within the last three years a partner or employee of such a firm and personally worked on our 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 our present executive officers at the same time serves or served on that company's compensation committee.

• The director is a current employee, or an immediate family member of the director is a current executive officer, of a company that has made payments to, or received payments from, us for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $1.0 million or 2% of such other company's consolidated gross revenues.

• The director is an executive officer of any charitable or non-profit organization to which we have made, within the preceding three years, contributions in any single fiscal year that exceeded the greater of $1.0 million, or 2% of such charitable or non-profit organization's consolidated gross revenues.

With the assistance of counsel, the Nominating and Corporate Governance Committee ("Governance Committee") reviews annually the applicable legal and NYSE standards for director independence, as well as our own independence criteria. Specifically, the Governance Committee reviews: (i) a summary of the answers to annual questionnaires completed by each of the directors (and, if applicable, any nominees for director); and (ii) to the extent applicable, a report of transactions and relationships, if any, between each director (and, if applicable, any nominee for director) and any of such director's family members and our Company, our

[**TABLE OF CONTENTS**](#TOC)

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

senior management, or our independent registered public accounting firm. To the extent such relationships do not change from year to year, the Governance Committee is informed that there have been no changes to such relationships.

In conducting its independence review, the Governance Committee specifically considered the relationships discussed under "Additional Information—Certain Relationships and Related Transactions—Transactions" other than the compensation arrangements, which are reviewed by the Compensation Committee. In addition, the Governance Committee considered (a) Ms. McGovern as a retired partner of Deloitte & Touche LLP and (b) Dr. Beckerle's position as CEO of the Huntsman Cancer Institute. Regarding Dr. Beckerle, the Governance Committee considered that Peter R. Huntsman does not have any ownership interest in the Institute, which is part of the University of Utah, a public institution of the state. The Governance Committee further considered that our Board recently approved a matching program pursuant to which our Company will match charitable contributions made by our employees to the Huntsman Cancer Foundation, a 501(c)(3) charity for which Peter R. Huntsman currently serves as the Chairman and CEO, and that the Huntsman Cancer Foundation contributes an annual, fixed amount of $100,000 as a supplement to Dr. Beckerle's annual compensation from the University of Utah for serving as the CEO of the Institute. Dr. Beckerle's annual compensation from the University of Utah is set by her supervisor, currently the University President, with no input from the Huntsman Cancer Foundation.

On the basis of its review, the Governance Committee delivered a report to the full Board and the Board made its independence determinations based on the Governance Committee's report and the supporting information. As a result of this review, the Board determined that Dr. Mary C. Beckerle, Sonia Dulá, Cynthia L. Egan, Curtis E. Espeland, Daniele Ferrari, Jeanne McGovern, José Muñoz, David B. Sewell and Retired Vice Admiral Jan E. Tighe, who currently constitute a majority of the Board, are independent. These independent directors currently comprise, in full, the membership of the Audit, Compensation, Governance and Sustainability committees of the Board discussed below.

Peter R. Huntsman, our CEO, is not an independent director because he is employed by our Company.

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

Under the independence criteria that the Board has adopted, which can be found on our website at *www.huntsman.com*, a member of the Audit Committee will not be considered independent if:

• The member receives directly or indirectly any consulting, advisory or other compensatory fee from us (other than director and committee fees and pension or other forms of deferred compensation for prior service, which compensation is not contingent upon continued service);

• An immediate family member of the member receives any consulting, advisory or other compensatory fee from us (other than director and committee fees and pension or other forms of deferred compensation for prior service, which compensation is not contingent upon continued service);

• An entity in which the member is a partner, member, an officer such as a managing director occupying a comparable position or executive officer, or occupies a similar position (except limited partners, non-managing members and those occupying similar positions, who, in each case, have no active role in providing services to the entity) and which provides accounting, consulting, legal, investment banking or financial advisory services to us receives any consulting, advisory or other compensatory fee from us; or

• The member is otherwise an affiliated person of our Company.

Furthermore, under these independence standards, (1) each member of the Audit Committee must be financially literate, (2) at least one member of the Audit Committee must have accounting or related financial management expertise and qualify as an "audit committee financial expert," and (3) no member of the Audit Committee may simultaneously serve on the audit committees of more than two other public companies. For purposes of (2) above, the Board considers any Audit Committee member who satisfies the SEC's definition of "audit committee financial expert" to have accounting or related financial management expertise.

The Board has determined that each member of the Audit Committee is independent as that term is defined by the listing standards of the NYSE and Rule 10A-3 promulgated under the Exchange Act and satisfies the additional independence criteria adopted by the Board and described above. The Board has also determined that Ms. McGovern is an "audit committee financial expert" as defined by the regulations of the SEC. No member of the Audit Committee currently serves on more than two other public company audit committees.

\*

Please see "Compensation Discussion and Analysis—How We Determine Executive Compensation" for additional information on the Compensation Committee's processes and procedures for the consideration and determination of executive officer and director compensation.

The Board has determined that each member of the Compensation Committee meets the independence requirements of the Exchange Act and the NYSE Listed Company Manual. The Compensation Committee's charter permits the Compensation Committee to form and delegate some or all its authority to subcommittees when it deems appropriate. In particular, the Compensation Committee may delegate the approval of both cash and equity award grants and other responsibilities regarding the administration of compensatory programs to a subcommittee consisting solely of members of the Compensation Committee who are non-employee directors or outside directors, or in some limited circumstances, to management.

The Compensation Committee typically meets at least four times each year to address various compensation issues and processes. Our CEO does not have the ability to call Compensation Committee meetings, but generally attends Compensation Committee meetings at the Chair of the Committee's request to answer questions and provide input regarding the performance of our executive

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

BOARD'S ROLE IN RISK OVERSIGHT

It is management's responsibility to assess and manage the various risks faced by the Company. It is the Board's responsibility to oversee management in this effort. The Audit Committee is responsible for administering the Board's oversight function, and the Committee establishes a mutual understanding of our Company's overall appetite for risk and risk philosophy through regular discussions with management. In exercising its oversight, the Audit Committee strives to effectively oversee our Company's enterprise-wide and financial risk management in a way that balances managing risks with enhancing the long-term value of our Company for the benefit of our stockholders. The Board understands that its focus on effective risk oversight is critical to setting the Company's tone and establishing our culture towards effective risk management.

The Audit Committee maintains an active dialogue with management about existing risk management processes and how management identifies, assesses and manages our most significant risk exposures. The Audit Committee receives regular presentations from management of our businesses and functions about significant risks the respective business or function faces, as well as regular and aggregated reports from an interdisciplinary risk management team of experts working within the Company, to assist the Audit Committee in evaluating Huntsman's risk assessment and risk management policies and practices.

In addition, each of our other committees assesses risks related to such committee's oversight activities. We believe that the oversight function of the Board and these committees combined with its active dialogue with management about effective risk management provides our Company with the appropriate framework to help ensure effective risk oversight.

#### OVERSIGHT OF CYBERSECURITY RISKS
We maintain a multi-pronged approach to identifying and mitigating information security risks, which includes utilization of multiple sources of threat intelligence, participation in industry cyber councils/groups, and active use of multi-layered detective and preventative controls. Our information security risk mitigation strategy includes a full defense in depth (DiD) and response/recovery plans for events that could potentially impact our information security. We maintain an information security awareness program and conduct regular testing to measure training effectiveness for continuous improvement. We also contract with third party cybersecurity firms to conduct simulated cyber-attacks on an annual basis and full cybersecurity risk/security assessments against the Cybersecurity Framework of the National Institute of Standards and Technology (NIST) and International Society of Automation (ISA) 62443 on a periodic basis. We maintain a security compliance program to assess against legal and regulatory frameworks in the countries in which we operate. We are not aware of any material information security breaches in the past three years.

Our Board has delegated the focused oversight of cybersecurity risks to the Audit Committee. In particular, our Audit Committee receives regular updates from senior management on cybersecurity risk reviews of our key business and operational areas, procedures to assess and address cybersecurity risk, and the effectiveness of cybersecurity technologies and solutions deployed internally. The Audit Committee regularly reports to our Board on these matters. At least one member of the Audit Committee has significant cybersecurity experience and expertise both at an operational and an oversight or management level.

The Enterprise Information Security function, led by our Chief Information Security Officer, supports the Audit Committee in the exercise of its oversight responsibility. The Enterprise Information Security team is tasked with (a) the identification and assessment of cyber risks; (b) the design and implementation of cyber risk mitigation controls; processes, and technologies; (c) oversight of our security training; and (d) ongoing monitoring and continuous improvement of our cyber security posture across our entire Information Technology and Operational Technology landscape.

CORPORATE RESPONSIBILITY

At Huntsman, corporate responsibility is an integral and integrated part of our business strategy. The key focus areas of our corporate responsibility program include our people, our health, safety and wellness programs, and our environmental stewardship, including our sustainability and product stewardship efforts.

Our sustainability program is led by our Corporate Sustainability Officer (CSO) and the Huntsman Sustainability Council, which is composed of senior representatives from all our divisions and key functions. Our CSO reports to the Governance Committee with respect to our environmental, health and safety compliance programs and performance, and to the Sustainability Committee with respect to sustainability and related corporate social responsibility matters. The Board also discusses on a regular basis our environmental, health and safety compliance programs and performance, as well as various environmental, social and governance (ESG) matters.

#### SUSTAINABILITY REPORTS
Since 2010, we have published annually a comprehensive sustainability report to document the Company's progress and performance, and to demonstrate our commitment to corporate responsibility. We prepare our sustainability disclosures in accordance

32 HUNTSMAN 2023 PROXY

[**TABLE OF CONTENTS**](#TOC)

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

with both the Global Reporting Initiative (GRI) and the Sustainability Accounting Standards Board (SASB) standards. For more information on our commitment to corporate responsibility, please visit *www.huntsman.com/sustainability*. Please note that information contained on the website is not incorporated by reference in this Proxy Statement or considered to be a part of this document. In 2022, we completed an analysis of the Task Force for Climate-Related Disclosures (TCFD) and began making TCFD-specific sustainability disclosures. Starting in 2022, we also began estimating and disclosing our full supply-chain related greenhouse gas emissions (Scope 3).

#### INNOVATIVE SOLUTIONS FOR A LOW-CARBON ECONOMY
The Company believes moving to a lower-carbon economy will improve the sustainability of both society and the environment. Accordingly, we announced our aspiration to achieve carbon neutrality by 2050. Even before that announcement, we were developing innovative solutions to improve energy efficiency and reduce emissions throughout each of our divisions, including high-performance, energy efficient building insulation, high-purity battery solvents that enable electric vehicles, and light-weight automotive and aerospace components, among others.

#### Our TEROL <sup>®</sup> Polyol process recycles the equivalent of 1.5 billion 500 ml plastic bottles
We make insulation from recycled plastic waste to improve energy efficiency in buildings and reduce greenhouse gas emissions. Through a proprietary process, we use the equivalent of over 1.5 billion 500 ml plastic bottles in TEROL<sup>®</sup> polyols every year. With a recycled content of up to 60%, these polyols become an essential part of MDI-based polyurethane insulation products. We also use TEROL<sup>®</sup> polyols in other insulation applications, including polyisocyanurate (PIR) boardstock systems and pour-in-place insulation for refrigerators and freezers, which prolong the shelf life of perishable foods.

The use of recycled bottles in TEROL<sup>®</sup> polyols gives plastic waste that might otherwise end up in a landfill or the ocean new purpose to save energy and reduce emissions. Demand for insulation that replaces "take, make, dispose" processes with "make, use, return" processes is growing at a rapid pace. In 2020, we added a new plant in Taiwan to increase our TEROL<sup>®</sup> polyols production, and we have also announced additional expansion plans in Europe.

#### Our US-produced Ethylene and Propylene Carbonates are a critical component of EV batteries
Electric vehicles will play a key role in reducing emissions in the transportation sector and we are at the forefront of expanding critical EV battery technology. We are the only U.S. producer and the largest supplier of ethylene and propylene carbonates used in Lithium-ion (Li-on) batteries in North America and are thus well positioned to grow with the electric vehicle industry.

We are expanding our plant in Conroe, Texas, to produce high-purity ethylene carbonate that Li-ion batteries require to meet the growing demand, especially in the U.S., where electric vehicle production is expected to reach 6.9 million units by 2025, a fivefold increase from today.

#### Our ARALDITE <sup>®</sup> Products are critical to making airplanes and automobiles more fuel-efficient
The transportation industry uses Huntsman's ARALDITE<sup>®</sup> products to manufacture airplanes and produce lighter and more fuel-efficient automobiles. Today, we also are creating products to insulate electric motors and build composite battery boxes that make electric vehicles lighter and safer—two key factors in growing this market and reducing vehicle emissions.

ARALDITE<sup>®</sup> resins insulate motors to improve their thermal and electrical performance, making electric vehicles more reliable and efficient. We are currently working with European, American and Chinese automotive companies and their suppliers to further develop and qualify these innovative technologies.

Additionally, ARALDITE<sup>®</sup> composite resin systems enable lightweight battery boxes to protect electric batteries from mechanical, thermal and fire damage, fostering widespread adoption and safer use of electric vehicles. Battery boxes have traditionally been composed of metal. However, as battery pack sizes increase, the protective boxes grow larger and increase the weight of the vehicle. Composite battery boxes made from ARALDITE<sup>®</sup> resins not only weigh less but also provide strong, fire-resistant protection that reduces the possibility of a fire in the event of a crash.

#### SUPPORT OF THE UNITED NATION'S GLOBAL COMPACT
We continue to support the United Nation's Ten Principles of the Global Compact (the "Ten Principles") with respect to human rights, fair labor practices, environment protection and anti-corruption. We have worked to ensure our corporate policies, procedures and guidance documents align with the Ten Principles and have made the Ten Principles a part of our business strategy. Our sustainability disclosures identify relevant Huntsman policies, procedures, systems, and actions that illustrate our progress.

DIRECTOR ATTENDANCE AT THE ANNUAL MEETING OF STOCKHOLDERS

We believe that there are benefits to having members of the Board attend our annual meetings of stockholders. From time to time, however, a member of the Board might have a compelling and legitimate reason for not attending an annual meeting. As a result, the Board has decided that director attendance at our annual meetings of stockholders should be strongly encouraged, but not required. All our directors attended the 2022 annual meeting.

DIRECTOR QUALIFICATION STANDARDS AND DIVERSITY

The minimum qualifications and specific qualities and skills required for directors are set forth in Criteria for Selecting New Directors and Section 1 of our Corporate Governance Guidelines. The Corporate Governance Guidelines require that a majority of directors on the Board meet the criteria for independence required by the NYSE and that each director functions consistent with the highest level of professional ethics and integrity. Each directors is expected to devote sufficient time and effort to learn the business of our Company and the Board, to use his or her own unique skills and experiences in providing independent oversight to our business, to participate in a constructive and collegial manner, to exhibit a high level of commitment to our Company, and to exhibit independent thought and judgment. When evaluating director nominees, our Criteria for Selecting New Directors require that the Governance Committee consider each candidate's background and lived experience (including his or her race, gender, ethnicity, identity or orientation), ability, judgment, skill, expertise and experience, and whether the candidate will enhance or contribute to the diversity of background, knowledge, expertise and experience of current Board members. The Governance Committee believes it is important for Board members to possess skills and knowledge in the areas of leadership of large, complex organizations, finance, accounting, strategic planning, legal, government relations and relevant industries, especially the chemical industry.

These considerations ensure that the Board, as a whole, possesses and manifests the appropriate mix of characteristics, skills and experiences for optimal functioning as an oversight body for our Company and management. As part of its periodic self-assessment process, the Governance Committee annually reviews and evaluates its performance, including the overall composition of the Board and the criteria that it uses for selecting nominees.

DIRECTOR NOMINATION PROCESS

The Governance Committee identifies director candidates through a variety of means, including recommendations from other Board members and management. From time to time, the Governance Committee may use third party search consultants to identify director candidates. The Governance Committee also welcomes stockholder recommendations for candidates for the Board. The Governance Committee uses the same process to screen all potential candidates, regardless of the source of the recommendation. The Governance Committee determines whether the candidate meets our minimum qualifications and possesses specific qualities and skills deemed appropriate for directors, and whether requesting additional information or an interview is appropriate.

A stockholder seeking to nominate a director candidate at an annual meeting must comply with the requirements set forth in our Bylaws. For additional information, please see the "Stockholder Proposals and Director Nominations For The 2024 Annual Meeting" section of this Proxy Statement.

Our Bylaws also allow eligible stockholders to nominate a candidate for election to our Board for inclusion in our proxy statement in accordance with the "proxy access" provisions of our Bylaws, which are contained in Section 2.14. The "proxy access" provisions allow a stockholder, or a group of up to 20 stockholders (with funds having specified relationships constituting a single stockholder), who own (as defined in our Bylaws) three percent or more of our outstanding common stock continuously for at least three years, to nominate and include in our proxy statement director candidates constituting up to two directors or 20% of the Board (rounded down to the nearest whole number), whichever is greater, provided that the stockholder(s) and the nominee(s) satisfy the requirements specified in our Bylaws (including similar information requirements to those set forth in Section 2.8 of our Bylaws).

The foregoing descriptions of our Bylaws are qualified in their entirety by reference to the full text of the Bylaws. Our Bylaws are available on our website at *www.huntsman.com* in the "Investor Relations" section. We will also furnish copies of our Bylaws free of

EXECUTIVE SUMMARY

The Compensation Committee believes that the design of our executive compensation program achieves its primary objective of aligning the financial interests of our NEOs with the creation of long-term stockholder value, as reflected by the pay outcomes in 2022.

The remainder of this CD&A provides additional information about the performance-based design of our executive compensation program, and how the Compensation Committee makes decisions to achieve our program objectives.

COMPENSATION PROGRAM HIGHLIGHTS

---

| | |
|:---|:---|
| **COMPANY PERFORMANCE HIGHLIGHTS**  | **COMPENSATION STRUCTURE AND OUTCOMES**  |
| &nbsp;&nbsp;&nbsp; 2022 was a notable year for our Company marked with significant milestones and strong performance on key financial, strategic, and ESG initiatives, including: <br> • **<u>Financial</u>**: Delivered $1.15 billion of adjusted EBITDA; exceeded goal for free cash flow; realized significant cost savings through our Optimization Program; and returned approximately $1.2 billion to stockholders through dividends and share repurchases <br>• **<u>Total Shareholder Return</u>**: Achieved a cumulative TSR of 25.8% for the three-year period ended December 31, 2022, which ranked fourth (in the 66.7<sup>th</sup> percentile) among our 2020 Performance Peers <br>• **<u>Strategic</u>:** Announced and closed on the sale of our Textile Effects Division to advance our focus on portfolio enhancement; completed $1 billion in share repurchases, building on the $682 million of share repurchases we completed between 2018 and November 2021; increased the dividend by 13% <br>• **<u>ESG</u>:** Published our 11th annual sustainability report showcasing disclosures in line with TCFD, SASB and GRI reporting standards and validated by a third party-Limited Assurance; outperformed our process safety goals <br>| &nbsp;&nbsp;&nbsp; The primary objective of our executive compensation program is to align the financial interests of our NEOs with the creation of long-term stockholder value.

---

#### OUR RESPONSE TO STOCKHOLDER FEEDBACK
We engage in a continuous dialogue with our stockholders and have made numerous changes over the years in response to stockholder feedback.

In response to stockholder feedback, the Compensation Committee has consistently implemented improvements that further align incentive payouts with the creation of stockholder value. Specifically, the Compensation Committee has gradually increased the weighting of performance share units from 30% of equity-based incentives in 2019, to 40% in 2020, 50% in 2021 and 70% in 2022.

In December 2021, as a part of our ongoing review of our executive compensation program and driven by the desire to better align pay outcomes across the Company with performance against preset goals, the Board authorized and is overseeing a multi-year compensation plan that covers all corporate officers and vice presidents, including NEOs, in December 2021. The vesting of these incentives, starting in 2022, is conditioned upon the achievement of the targets presented at our Company's Investor Day in November 2021 (and described below) with the specific intention of aligning the interests of our officers and other senior level employees with those of all long-term stockholders.

At our 2022 annual meeting, the say-on-pay proposal received the support of approximately 85% of the stockholders casting their votes. Both looking forward and back, the Compensation Committee carefully considers the say-on-pay results and the stockholder feedback we received in determining executive compensation.

Looking forward into 2023 and taking into account stockholder feedback, the Compensation Committee conducted a comprehensive assessment of our CEO's compensation. We also took into account (1) our desire for increased emphasis on performance-based

38 HUNTSMAN 2023 PROXY

------

[**TABLE OF CONTENTS**](#TOC)

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

compensation (i.e., pay at risk), and (2) our desire to more closely align executive pay in the Company with peer group practices. The Committee noted that Mr. Huntsman's total target direct compensation is competitively positioned within the Company's peer group, but concluded that the allocation of compensation components could be better aligned. Following the review, the Committee decided to reallocate Mr. Huntsman's total target direct compensation for 2023 as follows:

• Base salary of $1,300,000, a reduction of 24% from 2022;

• Target annual cash performance award of 140% of base salary; no change in the target percentage from 2022; and

• Target value of long-term incentives of $9,880,000, a 19% increase from his 2022 award.

This new allocation will result in 90% of Mr. Huntsman's total target direct compensation being tied to the Company's performance in 2023. The Compensation Committee believes the new mix among the components of Mr. Huntsman's total target direct compensation will achieve its core objectives as described above.

#### VAST MAJORITY OF 2022 NEO PAY REMAINS AT RISK <sup>(1)</sup>
Refocusing in 2022, our executive compensation program is designed to ensure that a significant portion of each officer's total target direct compensation is performance-based. As the charts below illustrate, for 2022, 86% of the CEO's total target direct compensation was at risk being tied to annual performance against preset goals and/or the performance of our stock. Comparably, 74% of total target direct compensation of our other NEOs in 2022, on average, was at risk.<sup>(2)</sup>

![[MISSING IMAGE: pc_target-pn.jpg]](pc_target-pn.jpg)

(1) NEO pay refers to "total target direct compensation" which consists of (i) annual base salary, (ii) the target annual cash performance award opportunity for 2022, and (iii) the aggregate grant date fair value of long-term equity incentive awards granted in 2022. The amounts actually realized by our NEOs with respect to the annual cash performance awards and long-term equity incentive awards granted in 2022 depend, as applicable, on the level of attainment of the relevant performance goals and the value of our common stock when the awards vest or are exercised.

(2) We consider compensation to be "at risk" if it is subject to performance-based payment or vesting conditions or if its value depends on stock price appreciation.

#### REALIZABLE PAY ANALYSIS
Realizable pay provides the Compensation Committee with a tool to validate the alignment of our NEOs' compensation with the creation of stockholder value, particularly because approximately 67% of our CEO's pay has been linked directly to our stock performance. Realizable pay reflects the tangible incentive value of equity awards and increases or decreases with fluctuations in market value. When determining the annual equity grants to our NEOs in February of each year, the Compensation Committee believes it is important to take into account not only the grant date values reported in our Summary Compensation Table, but also to consider the effect of the year-end value of our stock on those awards over time.

The chart below reflects our CEO's total target direct compensation and realizable pay<sup>(1)</sup> for 2020, 2021, and 2022. In each of the past three years, there has been a strong positive correlation between the realizable value of our CEO's compensation and our cumulative TSR.<sup>(2)</sup>

(1) Realizable pay for each year is defined as the sum of: (1) base salary, (2) annual cash performance award payout, and (3) the value of equity incentive awards granted in that year (i.e., performance share units, restricted stock and the "in the money" value of stock options) calculated using our stock price, in all cases, as of December 30, 2022 (the last trading day of fiscal year 2022).

(2) Cumulative TSR measured using the closing stock price at the beginning and end of the performance period and slightly differs from cumulative TSR we use to determine RSU payouts since such calculation is measured using a 20-trading day stock price average at the beginning and end of the performance period to smooth out volatility.

ELEMENTS OF HUNTSMAN'S EXECUTIVE COMPENSATION PROGRAM FOR 2022

Additional information about our executive compensation program is provided below, along with a discussion of how various compensation elements align with our compensation objectives.

#### TOTAL DIRECT COMPENSATION
We provide our executive officers with a mix of pay that reflects our belief that executive compensation should be tied to an appropriate balance of both short- and long-term performance. The Compensation Committee strives to align the relative proportion of each element of total direct compensation with the competitive market and our objectives, as well as to preserve the flexibility to respond to the continually changing global environment in which we operate.

While the Compensation Committee reviews the competitiveness of each NEO's total direct compensation, it does not target specific percentiles among peer companies when setting compensation levels. Rather, the Compensation Committee considers peer group data among several other factors in setting pay levels. Other factors include each executive's individual performance, level of responsibility, knowledge, tenure, and experience, as well as internal pay equity among executives with similar experience and job responsibilities.

Generally, as employees move to higher levels of responsibility with greater ability to influence financial results, the percentage of performance-based pay will increase. Total direct compensation received by our NEOs is comprised of the following elements:

---

| | | |
|:---|:---|:---|
| **Compensation Element**  | | **Description and Purpose of the Element**  |
| **Annual Cash <br> Compensation**  | **Base Salary**  | Reflective of the NEO's responsibilities, tenure, job performance, special circumstances (such as overseas assignments) and the market for the NEO's services.  |
| **Annual Cash <br> Compensation**  | **Annual Cash Performance Award**  | Cash performance awards are based on performance measured against preset goals and strategic initiatives. For 2022, 100% of our annual cash performance awards were linked to the achievement of the adjusted EBITDA margin, Optimization Program and Free Cash Flow targets set out at the 2021 Investor Day.  |
| **Long-Term Equity-Based Compensation**  | **Performance Share Units**  | Performance-based equity, the vesting of which is contingent on long-term performance against preset goals. For 2022, performance share units represented 70% of equity-based compensation for each of our NEOs, with equal weighting on three-year relative TSR and two-year free cash flow.  |
| **Long-Term Equity-Based Compensation**  | **Restricted Stock**  | Time-based equity with the realizable value of grants tied to the value of our common stock over the long term. Three-year ratable vesting provides both retentive value as well as a long-term focus. <br> For 2022, restricted stock represented just 30% of equity-based compensation for each of our NEOs.  |

---

A detailed discussion of 2022 total target direct compensation awarded to our NEOs and graphical illustrations of the proportionate amount of performance-based compensation, is set forth below in "—2022 Executive Compensation Decisions."

#### OTHER ELEMENTS OF COMPENSATION
In addition to the elements of total target direct compensation described above, our executive compensation program includes other elements of compensation that are designed primarily to attract, motivate, and retain executives critical to our long-term success and to provide a competitive compensation structure overall.

---

| | |
|:---|:---|
| **Element**  | **Description and Purpose of the Element**  |
| **Health and Welfare Benefits**  | We provide our NEOs with health and welfare benefits on the same basis as all employees. These benefits are comparable to those provided to employees and executives at other companies in the chemical industry and the general market.  |
| **Retirement and Savings Plans**  | We provide our NEOs with retirement and savings plan benefits that are comparable to those provided to employees and executives at other companies in the chemical industry and the general market. <br> For an explanation of the major features of our retirement and savings plans, see "Executive Compensation—Pension Benefits in 2022" and "—Nonqualified Deferred Compensation in 2022."  |
| **Perquisites**  | We provide our NEOs with limited perquisites that help enable the execution of their duties and are comparable to those provided at other companies in the chemical industry and the general market. <br> For a description of these perquisites and the amounts paid to our NEOs in 2022, see "Executive Compensation—2022 Summary Compensation Table" and "—Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table."  |
| **Severance Arrangements/Change in Control Benefits**  | Our NEOs other than Mr. Huntsman are entitled to payments and benefits upon certain severance events through the Huntsman Executive Severance Plan (the "Executive Severance Plan").<sup>(1)</sup> Mr. Huntsman has a separate severance arrangement. <br> These arrangements are designed to provide protection to our executive officers who are primarily tasked with the management of our overall operations and business strategy and are necessary to attract and retain executive talent for our business. We believe these arrangements are consistent with competitive market practices. <br> For a description of these arrangements, see "Executive Compensation—Potential Payments upon Termination or Change-in-Control."  |

---

(1) Mr. Hankins is eligible for the greater of the severance benefits payable to him under either the Executive Severance Plan or the U.K. business severance plan. Based on his entitlements under these plans, Mr. Hankins would receive payouts under the Executive Severance Plan.

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

2022 EXECUTIVE COMPENSATION DECISIONS

Our executive compensation program is designed such that a significant portion of each officer's total target direct compensation is performance-based. The Compensation Committee's decisions regarding the mix of pay reflects the Committee's and the Board's compensation philosophy, market reference data provided by Meridian and each officer's role in achieving our strategic objectives.

#### 2022 BASE SALARY CHANGES
The Compensation Committee reviews the base salaries of our NEOs annually to determine whether adjustments are necessary or appropriate. The Compensation Committee determined that Messrs. Hankins, Stryker and Rogers each received a modest increase to their base salary rate consistent with the salary adjustments provided to our employee population generally. Mr. Lister received a higher-than-average increase to improve alignment of his salary to comparables from the chemical industry and our Proxy Peers. Mr. Huntsman's base salary remained unchanged.

---

| | | | |
|:---|:---|:---|:---|
| **Executive Officer**  | **2021<sup>(1)</sup>**  | **2022<sup>(1)</sup>**  | **% Increase**  |
| Peter R. Huntsman | $1700000 | $1700000 | N/A |
| Philip M. Lister | $500000 | $600000 | 20.0% |
| Anthony P. Hankins | $1005402 | $1035564 | 3.0% |
| David M. Stryker | $593109 | $610902 | 3.0% |
| R. Wade Rogers | $502701 | $517782 | 3.0% |

---

(1) Changes in base salary rate are effective as of April 1 of the applicable year.

#### 2022 ANNUAL CASH PERFORMANCE AWARD
Our annual cash performance awards are designed to reward our NEOs for achievement of annual performance goals set by the Compensation Committee.

**2022 Award Pool.** Each year, the Compensation Committee establishes an award pool, which provides a mechanism to fund the annual cash performance awards. Under the formula used to establish the award pool, the maximum amount that could be paid to our executive officers covered by the award pool (including our NEOs) was 2% of adjusted EBITDA. Individual award amounts were limited to an allocated portion of the award pool for each covered officer. The Compensation Committee retains discretion to make awards to our executive officers that are less than their individual allocation. Actual awards paid to our NEOs under the 2022 award pool were based on the achievement of financial and strategic performance objectives discussed below.

**2022 Performance Measures and Goals.** The determination of the NEO's individual annual incentive awards is based on actual performance relative to specific financial and strategic performance measures, subject to the award pool limitation described above. The performance measures are selected because of their importance to our operations and contribution to the creation of stockholder value.

[**TABLE OF CONTENTS**](#TOC)

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

The following table provides additional detail regarding the performance measures selected for the 2022 annual cash performance awards.

---

| | | |
|:---|:---|:---|
| **Performance Measure**  | **What It Is**  | **Why We Believe It Is Important**  |
| **Adjusted EBITDA margin**  | The quality of our adjusted EBITDA, which is an indicator of general economic performance that is not affected by debt restructurings, fluctuations in interest rates or effective tax rates, or levels of depreciation and amortization  | Focuses our Company and its management on expanding our earnings multiple and a metric by which our stockholders measure our financial performance, thus aligning the interests of management with those of our long-term stockholders  |
| **Free cash flow**  | Operating cash from continuing operations less capital expenditures from continuing operations less net cash proceeds from the Albemarle settlement.  | Important measure of the financial performance of our Company with a significant impact on our strategic planning, liquidity and the ability to reduce our leverage through cash repayments on outstanding debt  |
| **Optimization Program**  | A metric aimed at increasing operational efficiency across the enterprise and reducing annual run rates for divisional and functional operating costs  | Focuses our Company and its management on specific value creation initiatives such as M&A, site consolidation and/or closures, divisional rightsizing, implementing regional GBS centers, strategic vendor management, commercial excellence programs and supply chain optimization  |
| **EH&S performance**  | Measures achievement of environmental performance and injury reduction objectives  | Discourages risk-taking for short-term profits to the detriment of the long-term health of our Company  |

---

The Compensation Committee also established threshold, target, and maximum performance goals for each of the financial performance measures relevant to our NEOs (dollars in millions):

---

| | | | |
|:---|:---|:---|:---|
| **Performance Measure**  | **Threshold**  | **Target**  | **Maximum**  |
| Adjusted EBITDA margin | 16.0%  | 16.5%  | 17.0%  |
| Free cash flow | $439.7 | $513.0 | $549.6 |
| Optimization Program | $120.0 | $160.0 | $180.0 |

---

Targets are set at aggressive levels that are intended to require significant effort to achieve. Achievement levels between threshold and target result in payouts from 0% to 100% of target awards. Achievement levels between target and maximum result in payouts from 100% to 200% of target awards. The Compensation Committee believes that requiring a minimum adjusted EBITDA threshold be met to receive any payment with respect to the annual cash performance awards both aligns executives' interests with those of stockholders and prevents excessive annual cash performance award payments in times when our financial performance fails to meet our expectations. If we achieve adjusted EBITDA of less than 85% of target, the payout for all other components may be capped at target at the discretion of the Compensation Committee. If adjusted EBITDA is less than the threshold goal of 75% of target, then payment of any other component of the award would be at the discretion of our CEO and the Compensation Committee.

***2022 Annual Cash Performance Award Design.*** The Compensation Committee establishes target annual cash performance award amounts for the NEOs set as a percentage of their base salaries. The following table summarizes the target and maximum annual cash performance award amounts, performance measures and corresponding weightings for each of our NEOs for 2022.

The target and maximum cash performance award amounts for the NEOs were set to generally align with competitive levels relative to comparable executive positions at our Proxy Peers (as defined below) and other chemical and general industrial companies. Potential payouts of individual annual cash performance awards depend upon both Company performance and individual contributions to our success, with the target and maximum award amounts serving as guidelines for ultimate payouts. The awards may be modified based on EH&S performance as discussed below.

**2022 Financial Performance.** For 2022, actual performance and performance as a percentage of targets were as follows (all dollar amounts are in millions):

---

| | | | |
|:---|:---|:---|:---|
| **Performance Criteria**  | **2022 Target <br> Performance**  | **2022 Actual <br> Performance**  | **% of <br> Target**  |
| Adjusted EBITDA margin | 16.5%  | 14.4%  | 87.3% |
| Free cash flow | $513.0 | $542.7 | 105.8% |
| Optimization Program | $160.0 | $195.9 | 122.4% |

---

**2022 EH&S Performance.** For each of our NEOs, our EH&S performance was measured against preset goals including: (a) ASTM 2920 Level 1 injury rate; and (b) process severity index, each of which is a performance measure of our injury reduction objectives. A shortfall in achieving our EH&S performance targets results in a reduction of 5% of the overall payout. The actual performance and performance as a percentage of targets in 2022 were as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Performance Criteria**  | **2022 Performance <br> Target**  | **2022 <br> Performance**  | **% of <br> Target**  |
| ASTM 2920 Level 1 injury rate | 0.160 | 0.209 | 76.6% |
| Process severity index | 0.150 | 0.118 | 127.1% |

---

**2022 Annual Cash Performance Awards.** Actual incentive awards are determined as follows:

![[MISSING IMAGE: fc_cashperf-pn.jpg]](fc_cashperf-pn.jpg)

The overall performance score reflects the weighted average results of our performance relative to the goals set for each performance measure, as described above. The final annual cash performance award for each NEO was reduced by 5% due to a shortfall in the ASTM 2920 Level 1 injury rate performance criteria. The CEO presents the Compensation Committee with recommendations

for the annual cash performance awards for each of the other executive officers, including the other NEOs. The Compensation Committee reviews the CEO's recommendations, as well as the CEO's performance, and makes such adjustments as it deems appropriate in its determination of the award payouts.

Based on our performance results discussed above, the Compensation Committee awarded the following annual cash performance awards for 2022.

---

| | | | |
|:---|:---|:---|:---|
| **Executive Officer**  | **Target Award <br> Amounts**  | **% of Target <br> Award Earned**  | **Cash Performance <br> Award Earned**  |
| Peter R. Huntsman | $2380000 | 120.65% | $2871576 |
| Philip M. Lister | $480000 | 120.65% | $579141 |
| Anthony P. Hankins | $828452 | 120.65% | $999564 |
| David M. Stryker | $488722 | 120.65% | $589664 |
| R. Wade Rogers | $362447 | 120.65% | $437309 |

---

#### LONG-TERM EQUITY COMPENSATION
For 2022, the Compensation Committee approved the grant of 1) performance share units that would vest upon the achievement of relative TSR milestones; and 2) time-based restricted stock. The Compensation Committee believes relative TSR is an appropriate long-term performance metric for the performance share units because it promotes stockholder alignment and is a prevalent metric used by our peer companies. To further align performance share outcomes with the creation of stockholder value, if absolute TSR is negative, the number of performance share units that can vest at the end of the performance period is capped at the target number of performance share units,

**Equity Award Mix.** For 2022, the Compensation Committee approved an award mix of performance share units (70% value) and restricted stock (30% value). At the time, the Compensation Committee believed this increased emphasis on performance further enhances the mix of long-term equity-based incentives by further linking payouts to achievement of three-year relative TSR.

The following table illustrates the evolution of our long-term equity-based compensation in the last three years.

---

| | | | |
|:---|:---|:---|:---|
| **Fiscal Year**  | **Performance <br> Share Units**  | **Stock <br> Options**  | **Restricted <br> Stock**  |
| 2020 | 40% | 20% | 40% |
| 2021 | 50% | 0% | 50% |
| 2022 | 70% | 0% | 30% |

---

The Compensation Committee targeted long-term equity compensation awards for the NEOs at levels intended to competitively position the total target direct compensation of the executive officers and to reflect the individual roles and contributions of our NEOs. The target award amounts were converted to a number of shares based on the stock price on the date of the respective award grants. The 2022 long-term equity incentive awards approved for the NEOs were as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Executive Officer**  | **Target <br> Performance <br> Share Units<sup>(1)(2)</sup>**  | **Restricted Stock**  | **Total Target <br> Award Value**  |
| Peter R. Huntsman | 141570 | 60673 | $8300000 |
| Philip M. Lister | 22174 | 9503 | $1300000 |
| Anthony P. Hankins | 34114 | 14620 | $2000000 |
| David M. Stryker | 23880 | 10234 | $1400000 |
| R. Wade Rogers | 17960 | 7697 | $1053000 |

---

**Performance-Based Awards Granted in 2022.** The relative TSR performance share units granted in 2022 comprise 50% of the target performance share units and will vest or lapse on December 31, 2024, depending on the achievement of relative TSR performance during the performance period from January 1, 2022 to December 31, 2024, subject to the executive's continued service. To ensure better alignment of payouts with stockholder value created, in cases where absolute TSR is negative at the end

47 HUNTSMAN 2023 PROXY

[**TABLE OF CONTENTS**](#TOC)

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

of the performance period, any payout would be capped at the target number of performance share units even if relative TSR performance would have resulted in a payout above target. The performance share unit awards are settled in stock upon vesting and any dividends paid with respect to the underlying shares are accumulated and paid when and to the extent the award vests and is earned, either in cash or additional shares at the Compensation Committee's election.

The Company peer group used to determine relative TSR performance (the "2022 Performance Peers") represents industry-specific public companies. Although there is some overlap between the two groups, the 2022 Performance Peers as further described below differ from our Proxy Peers in that our 2022 Performance Peers are companies whose valuations are influenced by similar financial measures and we compete against these companies for market share and investor capital.

The free cash flow performance share unit awards granted in 2022 comprise 50% of the target performance share units and vest on December 31, 2023, subject to the achievement of cumulative free cash flow subject to continued service. The number of performance share units shall be increased by 20% if our relative TSR is above the 75th percentile of our 2022 Performance Peers over the performance period. Conversely, the number of performance share units shall be decreased by 20% if our relative TSR against our 2022 Performance Peers over the performance period is at or below 25th percentile.

The 2022 Performance Peers, which we developed with guidance from Meridian, were as follows:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;&nbsp; • Ashland Global Holdings Inc. <br>| &nbsp;&nbsp;&nbsp; • Covestro AG <br>| &nbsp;&nbsp;&nbsp; • H.B. Fuller Company <br>|
| &nbsp;&nbsp;&nbsp; • BASF Corp. <br>| &nbsp;&nbsp;&nbsp; • Dow Inc. <br>| &nbsp;&nbsp;&nbsp; • Lanxess AG <br>|
| &nbsp;&nbsp;&nbsp; • Celanese Corporation <br>| &nbsp;&nbsp;&nbsp; • Eastman Chemical Company <br>| &nbsp;&nbsp;&nbsp; • Trinseo S.A. <br>|
| &nbsp;&nbsp;&nbsp; • Clariant AG <br>| &nbsp;&nbsp;&nbsp; • Evonik <br>| &nbsp;&nbsp;&nbsp; • Westlake Chemical <br>|

---

For each 2022 Performance Peer, TSR is measured using a 20-trading day stock price average at the beginning and end of the performance period to smooth out volatility. Determination of payouts, if any, will be made based on our TSR percentile performance relative to the 2022 Performance Peers at the end of the performance period. The maximum number of performance share units that may be earned under the program is 200% of the target number of shares granted if our TSR performance ranks in the 90<sup>th</sup> percentile of the 2022 Performance Peers. If our TSR performance ranks below the 25<sup>th</sup> percentile of the 2022 Performance Peers, there can be no payout. Median performance at 50<sup>th</sup> percentile results in payout at target.

Additional details regarding these 2022 grants are provided under "Executive Compensation—Grants of Plan-Based Awards in 2022" below.

**Time-Based Awards Granted in 2022.** The restricted stock granted in 2022 are subject to a three-year ratable annual vesting schedule that requires service for a continuous three-year period to become fully vested.

**Payout of 2020 Performance Share Unit Awards.** Payouts for the 2020-2022 performance share unit cycle were based on our relative TSR results for the three-year period ended December 31, 2022. Payouts could range from 0% to 200% of target based on the Company's TSR ranking relative to the nine companies in the performance peer group established upon the grant date in 2020. The "2020 Performance Peers" were as follows:

• Albemarle Corporation • Clariant AG • Eastman Chemical Company <br> • Ashland Inc. • Covestro AG • H.B. Fuller Company <br> <u> • Celanese Corporation </u> <u> • Dow Inc. </u> <u> • Lanxess AG </u>

Based on the award parameters, the Company's TSR of 25.8% for the three-year period ended December 31, 2022 ranked fourth (in the 66.7<sup>th</sup> percentile) among the 2020 Performance Peers, resulting in a final payout of 150.0% of the target number of performance share units awarded. Based on the result, the Compensation Committee approved the payout of the following number of shares:

---

| | | |
|:---|:---|:---|
| **Executive Officer<sup>(1)</sup>**  | **Target Award <br> Amount**  | **Number of Shares <br> Earned**  |
| Peter R. Huntsman | 141133 | 211700 |
| Anthony P. Hankins | 32498 | 48747 |
| David M. Stryker | 24141 | 36212 |
| R. Wade Rogers | 18570 | 27855 |

#### CONSIDERATION OF PEER COMPENSATION
To assist in its determination of the 2022 target total direct compensation levels for our executive officers, the Compensation Committee directed Meridian to undertake a compensation benchmarking review for each element of compensation, as well as information regarding incentive plan designs and pay practices for executives in similar positions among a selected peer group of companies (the "Proxy Peers"). Information in the compensation peer review served as a reference in the Compensation Committee's

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

overall assessment of the competitiveness of our executive compensation program. Criteria used to select the Proxy Peer companies include financial measures (i.e., revenue, market capitalization and/or net income) and the industry segment in which we operate.

As a result of a comprehensive review in mid-2021, the Compensation Committee approved the addition of six companies to the Proxy Peers. The changes were made to position Huntsman near the median in terms of size (as measured by revenues), better align with certain external perspectives, and offer a more robust data set for conducting competitive benchmarking. For the compensation benchmarking review that informed the 2022 compensation decisions, our Proxy Peers consisted of the following 20 companies:

---

| | | |
|:---|:---|:---|

As a supplement to competitive market data from the Proxy Peers, and to assess data for positions in which pay information is not publicly disclosed, the Compensation Committee also considered competitive market data across a broader group of chemical and general industrial companies. These data points were provided by the Equilar Executive Compensation Survey and were included in the compensation peer review. The Compensation Committee considers competitive ranges among our Proxy Peers and the broader industry groups and does not use the data to target specific percentiles within these groups.

The Compensation Committee believes the combination of these perspectives and points of reference offers an appropriate basis for assessing the competitiveness of the compensation for our NEOs.

#### INDEPENDENCE OF COMPENSATION ADVISERS
Since 2011, the Compensation Committee has retained Meridian as its compensation consultant. Meridian is an independent compensation consulting firm and does not provide any services to us outside of matters pertaining to executive officer and director compensation. Meridian reports directly to the Compensation Committee, which is solely responsible for determining the scope of services performed by Meridian and the directions given to Meridian regarding the performance of such services. Meridian attends Compensation Committee meetings as requested by the Compensation Committee.

The Compensation Committee determined that the services provided by Meridian to the Compensation Committee during 2022 did not give rise to any conflicts of interest. The Compensation Committee made this determination by assessing the independence of Meridian under the six independence factors adopted by the SEC and incorporated into the NYSE Corporate Governance Listing Standards. Further, in making this assessment, the Compensation Committee considered Meridian's written correspondence to the Compensation Committee that affirmed the independence of Meridian and the partners, consultants and employees who provide services to the Compensation Committee on executive and director compensation matters.

COMPENSATION POLICIES AND PRACTICES

#### STOCK OWNERSHIP GUIDELINES
The Board has adopted Director and Executive Stock Ownership Guidelines (the "Guidelines") to more closely align the interests of our directors and executives with those of our long-term stockholders through all industry cycles and market conditions. The Guidelines require directors and executive officers to achieve and maintain ownership of our stock equal to six times base salary for the CEO, three times base salary for all other executive officers and three times the annual cash retainer for directors. The stock ownership requirement is based on the participant's base salary or annual retainer (as applicable) and the closing stock price on July 15 of each calendar year.

During any year in which a director or executive does not meet the applicable ownership target, the director or executive is required to retain at least 50% of net shares delivered through the Company's stock incentive plans ("net shares" means the shares remaining after deducting shares for the payment of taxes and, in the case of stock options, after deducting shares for payment of the exercise price of stock options). Shares acquired by a participant prior to becoming subject to the Guidelines are not subject to the retention restriction. There are exceptions to the retention requirement for estate planning, gifts to charity, education and a participant's primary residence. In addition, hardship exemptions may be made in rare instances. A copy of the Guidelines is available on our website at *www.huntsman.com.* 

As of July 15, 2022, all of our directors and NEOs have either met these guidelines or are progressing toward meeting the guidelines within a reasonable period of time. The following table provides the minimum stock ownership level for each NEO, and the percentage of the ownership guideline achieved by the executive officer as of July 15, 2022:

| R. Wade Rogers | &nbsp;&nbsp;&nbsp;&nbsp; 3x | 53900 | >100% |

---

#### CLAWBACK POLICY
Under our Executive Compensation Clawback Policy, we may recover performance-based compensation that was based on achievement of quantitative performance targets if an executive officer engaged in fraud or intentional illegal conduct materially contributing to a financial restatement. We may also recover any awards made to an executive during the prior three years should the executive engage in activity that materially contributes to a financial restatement. A copy of the Clawback Policy is available on our website at *www.huntsman.com.* 

#### POLICIES ON HEDGING AND PLEDGING
We do not generally prohibit all transactions designed to hedge or offset decreases in the market value of our equity securities. However, our Insider Trading Policy includes certain trading restrictions, which prohibit employees (including our officers), directors and related persons from engaging in short-term speculative transactions in our securities. Such persons may not execute short sales or transactions in options (such as puts and calls) or any other derivative securities on a securities exchange, in any other organized market or in a private transaction. As of the date of this Proxy Statement, none of our directors or executive officers has engaged in any hedging transactions.

While we do not prohibit pledging shares, persons subject to our Insider Trading Policy are required to exercise caution when holding securities in a margin account where such securities could be pledged as collateral.

#### COMPENSATION POLICIES AND PRACTICES AS THEY RELATE TO RISK MANAGEMENT
The Compensation Committee believes that our compensation programs are appropriately designed to provide a level of incentives that does not encourage our executive officers and employees to take unnecessary risks in managing their respective business divisions or functions and in carrying out their employment responsibilities. Specifically:

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• a substantial portion of our executive officers' compensation is performance-based, consistent with our approach to executive compensation;

• our annual cash performance award program is designed to reward annual financial and/or strategic performance in areas considered critical to our short- and long-term success and features a cap on the maximum amount that can be earned in any single year;

• we measure performance in many areas other than Company profit, such as environmental, health and safety goals, cost saving initiatives and corporate compliance, to determine an executive's annual cash performance award;

• our long-term equity incentive awards are intended to be aligned with long-term stockholder interests through their link to our stock price, TSR and multi-year ratable vesting schedules;

• our executive stock ownership guidelines are intended to provide a long-term focus by requiring our executives to personally hold significant levels of our stock; and

• we maintain a clawback policy that is intended to discourage risk-taking that focuses excessively on short-term financial performance.

The Compensation Committee believes that the various elements of our executive compensation program sufficiently incentivize our executives to act based on the sustained long-term growth and performance of our Company.

ACCOUNTING AND TAX TREATMENT OF THE ELEMENTS OF COMPENSATION

The financial reporting and income tax consequences to us of individual compensation elements are important considerations for the Compensation Committee, which takes into account, among other considerations, Internal Revenue Code Section 162(m) limitations on the deductibility of compensation in excess of $1 million paid to certain covered individuals, including each of our NEOs, in any calendar year.

COMPENSATION COMMITTEE REPORT

The Compensation Committee has reviewed and discussed Huntsman Corporation's Compensation Discussion and Analysis for the fiscal year ended December 31, 2022 as set forth above with Huntsman management. Based on this review and discussion, the Compensation Committee recommended to the Board that the Compensation Discussion and Analysis be included in this Proxy Statement.

(1) This column reflects the aggregate grant date fair value of awards of restricted stock and performance share units for each NEO computed in accordance with FASB ASC Topic 718, disregarding the estimate of forfeitures. For purposes of restricted stock awards, fair value is calculated using the closing price of our stock on the date of grant. For purposes of performance share unit awards, the amount shown reflects the full grant date fair value computed in accordance with FASB ASC Topic 718 based on probable achievement of the market conditions, which is consistent with the estimate of aggregate compensation to be recognized over the service period, excluding the effect of estimated forfeiture. The value of the award at the grant date assuming that the highest level of performance conditions will be achieved is $15,272,092, $2,392,016, $3,680,057, $2,576,080, and $1,937,457 for Messrs. Huntsman, Lister, Hankins, Stryker, and Rogers, respectively. For information on the valuation assumptions regarding stock awards, refer to the notes to our financial statements in our annual report on Form 10-K for the applicable year ended December 31, 2022, 2021, or 2020, respectively, as filed with the SEC. These amounts reflect the fair value of the reported awards on the date of grant and may not correspond to the actual value that will be recognized by the NEOs.

(2) This column reflects the aggregate grant date fair value of stock options for each NEO computed in accordance with FASB ASC Topic 718, disregarding the estimate of forfeitures. The fair value of each stock option award is determined on the date of the grant using the Black-Scholes valuation model. For information on the valuation assumptions regarding option awards, refer to the notes to our financial statements in our annual report on Form 10-K for the applicable year ended December 31, 2022, 2021, or 2020, respectively, as filed with the SEC.

(3) This column reflects the annual cash performance awards that were earned for the years included. Amounts for 2022 will be paid during the first quarter of 2022. These awards are discussed in further detail under "Compensation Discussion and Analysis—2022 Executive Compensation Decisions—2022 Annual Cash Performance Award."

(4) This column reflects the aggregate amount of any change in pension value for the years included for each of the NEOs, to the extent any such aggregate change is positive. See "—Pension Benefits in 2022" for additional information regarding the 2022 amounts, including the present value assumptions used in this calculation. None of the NEOs had above market or preferential earnings on nonqualified deferred compensation during 2022. See "—Nonqualified Deferred Compensation in 2022" for additional information.

(5) The methodology used to compute the cost of perquisites and other personal benefits for each individual NEO is based on the cost to our Company calculated in accordance with SEC rules. The table below details the components reported in the "All Other Compensation" column of the Summary Compensation Table for 2022.

Mr. Huntsman used 34.1 flight hours in 2022. Contributions to the Supplemental Savings Plan on Mr. Huntsman's behalf are included in our Nonqualified Deferred Compensation Table below. In 2022, we incurred $7,993 to gross up Medicare taxes associated with our contributions to the Supplemental Savings Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (b)

Mr. Lister used 7.3 flight hours in 2022. Contributions to the Supplemental Savings Plan on Mr. Lister's behalf are included in our Nonqualified Deferred Compensation Table below. In 2022, we incurred $1,942 to gross-up Medicare taxes associated with our contributions to the Supplemental Savings Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (c)

Mr. Hankins used 2.6 flight hours in 2022. As a citizen of the U.K. with residence in the U.S., we incurred foreign assignment costs on Mr. Hankins' behalf during 2022 that included $53,786 in housing allowances and costs and $88,802 for perquisites, including foreign assignment and car allowances. In addition, we incurred $157,381 in tax gross ups and equalization associated with Mr. Hankins' foreign assignment. Contributions to the Supplemental Savings Plan on Mr. Hankins' behalf are included in our Nonqualified Deferred Compensation Table below. In 2022, we incurred $4,904 to gross-up Medicare taxes associated with our contributions to the Supplemental Savings Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (d)

Contributions to the Supplemental Savings Plan on Mr. Stryker's behalf are included in our Nonqualified Deferred Compensation Table below. In 2022, we incurred $200 to gross-up Medicare taxes associated with our contributions to the Supplemental Savings Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (e)

Contributions to the Supplemental Savings Plan on Mr. Rogers' behalf are included in our Nonqualified Deferred Compensation Table below. In 2022, we incurred $1,458 to gross-up Medicare taxes associated with our contributions to the Supplemental Savings Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (f)

From time to time, our executive officers may use our Company aircraft for commuting and other related purposes. We generally consider costs related to commuting use of our Company aircraft to be necessary business expenses for reasons of security, personal safety, and efficiency. However, SEC rules require that we include in the "Summary Compensation Table" the incremental cost to us of certain flights or portions of certain flights as a perquisite. Therefore, the amounts shown for Mr. Huntsman and Mr. Hankins for use of our Company aircraft primarily reflect the aggregate incremental cost to our Company for: (i) elements of business or business-related flights and (ii) all personal flights taken for non-commuting, non-business purposes. All use of our Company aircraft by our NEOs in 2022 was consistent with our Aircraft Use Policy. See "—Narrative Disclosure to Summary Compensation Table and Grants of Plan Based Awards Table—Aircraft Use Policy" for additional information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (g)

The incremental cost to us of personal use of our Company aircraft includes costs related to fuel, maintenance, repairs, navigation, aircraft supplies, crew travel, catering, etc. Because our aircraft is used primarily for business travel, this methodology excludes fixed costs that do not change based on usage, such as the salaries and benefits of pilots and crew, amortization cost of aircraft, and depreciation. The reported amounts are determined based on the number of flight hours used by our NEOs. The hourly rate of incremental cost is calculated quarterly and may result in variances from quarter to quarter.

(6) For reporting purposes, the 2022 pension value for Mr. Hankins has been converted using an exchange rate of 1 GBP to 1.3401 USD, which was the exchange rate as of February 28, 2022 (which is the internal date used to estimate pro forma elements of compensation). Values for 2020 and 2021 were calculated based on exchange rates applicable in those years and have not been recast to conform to the 2022 GBP exchange rate.

(1) These columns show annual cash performance awards granted under our annual cash performance award program to the NEOs in 2022. See the chart and accompanying narrative disclosure in "Compensation Discussion and Analysis—2022 Executive Compensation Decisions—2022 Annual Cash Performance Award" for additional information with respect to these amounts. The amounts reported in the table represent the target and maximum cash performance award guidelines established by the Compensation Committee but do not reflect the maximum annual dollar denominated incentive award amount that could be paid under the annual pool program to our executive officers (including our NEOs), which in 2022 may not exceed 2% of corporate adjusted EBITDA. The amounts actually earned by each of the NEOs pursuant to our annual cash performance award program for 2022 are reported in the "Non-Equity Incentive Plan Compensation" column of the Summary Compensation Table.

(2) These columns show performance share units granted under the 2016 Stock Incentive Plan to the NEOs in 2022 as follows:

(3) This column shows the number of restricted shares granted under the 2016 Stock Incentive Plan to the NEOs in 2022. The restricted shares vest ratably in three equal annual installments beginning on the first anniversary of the grant date. During the restriction period, each restricted share entitles the individual to vote such share, and each restricted share entitles the individual to accrue quarterly payments by us equal to the quarterly dividend on one share of our common stock. However, dividends and distributions made on restricted shares are held by us without interest until the restricted shares with respect to which the dividend or distribution was made become vested.

NARRATIVE DISCLOSURE TO SUMMARY COMPENSATION TABLE AND GRANTS OF PLAN-BASED AWARDS TABLE

Information regarding the elements of our executive compensation program for 2022 is provided above under "Compensation Discussion and Analysis." The following is a discussion of what we consider to be material factors necessary to obtain an understanding of information disclosed under "2022 Summary Compensation Table" and "Grants of Plan-Based Awards in 2022" that is not otherwise discussed in the Compensation Discussion and Analysis.

**Aircraft Use Policy.** We have an Aircraft Use Policy to carefully manage use of our aviation assets in a manner that best meets the goals of improving senior management's effectiveness and availability. Under this policy, members of the Board, executive management, and key employees that are approved by our CEO may, from time to time, utilize our Company aircraft for business and personal use. Priority for the use of the Company aircraft is chosen on the basis of the business purpose containing the greatest benefit for our Company and is determined by our CEO or his designee. The aggregate incremental costs for certain use by our NEOs of our Company aircraft are reported in the "All Other Compensation" column of the Summary Compensation Table.

To mitigate security concerns and to maximize time available to spend on Company business, our CEO should endeavor to use the Company aircraft for business, as well as personal travel. For 2022, the Compensation Committee permitted our CEO to have unlimited personal use of Company aircraft without cost. We do not make gross-up payments for out-of-pocket tax obligations resulting from any personal use of our Company aircraft.

**Company Car.** We provide executive officers with leased vehicles for business use, which executives may also use for personal transportation. Executive officers are responsible for the taxes on imputed income associated with the personal use of these vehicles.

**Foreign Assignment.** In accordance with our practice with respect to employees on assignment in a foreign country, Mr. Hankins entered into a letter agreement, effective as of October 26, 2000, with our subsidiary Huntsman Polyurethanes Americas, now known as Huntsman International LLC, detailing the terms of his secondment from Huntsman Polyurethanes (UK) Ltd. The primary purpose of this letter agreement is to provide Mr. Hankins with details regarding repatriation to his home country following the completion of his foreign assignment. This letter agreement also defines the initial elements of Mr. Hankins' compensation package, including base salary and an annual cash performance award, and provides for customary expatriation arrangements, including an international location allowance expressed as a percentage of annual salary, as well as sports and social club membership fees and an education allowance.

**Family Travel.** Travel costs for family members of employees or consultants are reimbursable by our Company under limited circumstances. Employees and consultants are generally responsible for any taxable income associated with this reimbursement.

(2) Restricted stock awards vest and lapse their associated restrictions ratably in three equal annual installments on the first three anniversaries of each respective grant date. Restricted stock awards have generally been granted on the same day as option awards and vest on the same schedule as footnoted for option awards above. As of December 31, 2022, the restricted stock awards granted on February 13, 2020, vested as to 66<sup>2</sup>∕3% on February 13, 2020, and will vest as to 100% on February 13, 2023. The outstanding restricted stock awards granted on February 17, 2121, vested as to 33<sup>1</sup>∕3% on February 17, 2022, and will vest as to 66<sup>2</sup>∕3% on February 17, 2023, and as to 100% on February 17, 2024.

The outstanding restricted stock awards granted on July 1, 2021, vested as to 33<sup>1</sup>∕3% on July 1, 2022, and will vest as to 66<sup>2</sup>∕3% on July 1, 2023, and as to 100% on July 1, 2024.

(3) The market value of unvested restricted stock is calculated by multiplying $27.48 the closing market price of our stock on December 30, 2022 (the last trading day of fiscal year 2022), by the number of unvested restricted shares as of December 31, 2022, for each restricted stock grant listed above.

(4) The performance share units granted on February 13, 2020, have a performance period of three years ended on December 31, 2022, subject to the achievement of relative TSR performance metrics. Amounts in this table with respect to the 2020 grant reflect an estimated payout of a number of shares based on the maximum level of achievement with respect to the applicable performance metrics, as performance through December 31, 2022, was above the target performance level. The shares were not deemed fully vested until certification occurred in February 2023. The performance share units granted on February 17, 2021, have a performance period of three years ending on December 31, 2023, also subject to the achievement of relative TSR performance metrics. Amounts in this table with respect to the 2021 grant reflect an estimated payout of a number of shares based on the maximum level of achievement with respect to the applicable performance metrics, as performance through December 31, 2022, exceeded the target performance level. The performance share units granted on February 17, 2022, have a performance period of three years ending on December 31, 2024, also subject to the achievement of relative TSR performance metrics. Amounts in this table with respect to the 2022 three-year grant reflect an estimated payout of a number of shares based on the target level of achievement with respect to the applicable performance metrics, as performance through December 31, 2022, met the target performance level. Additionally, the performance share units granted on February 17, 2022, have a performance period of two years ending on December 31, 2023, also subject to the achievement of relative TSR performance metrics with a modifier based on adjusted corporate free cash flow. Amounts in this table with respect to the 2022 two-year grant reflect an estimated payout of a number of shares based on the target level of achievement with respect to the applicable performance metrics, as performance through December 31, 2022, met the target performance level.

(5) The market value of unvested performance share units reported in this column is calculated by multiplying $27.48, the closing market price of our stock on December 30, 2022 (the last trading day of fiscal year 2022), by the number of unvested performance share units as of December 31, 2022, based on the level of achievement with respect to the applicable performance metrics.

(1) The number of years of service credited to the NEO is determined using the same pension plan measurement date used for financial statement reporting purposes. These assumptions are discussed in "Note 18. Employee Benefit Plans" to our consolidated financial statements included in our 2022 Form 10-K.

(2) The actuarial present value of the accumulated benefits is determined using the same pension plan measurement date and assumptions as used for financial reporting purposes. These assumptions are discussed in "Note 18. Employee Benefit Plans" to our consolidated financial statements included in our 2022 Form 10-K. For purposes of performing these calculations, a normal retirement (earliest unreduced) age of 65 was utilized for Messrs. Huntsman, Stryker, Lister, and Rogers. Mr. Hankins has passed the normal retirement age of 62; therefore, age 64 was used to calculate his accrued benefits. All accrued benefits are assumed payable at the plan's earliest unreduced retirement age. Benefit values reported in this table have been projected out to assume payment at the normal retirement age then have been discounted back to a present value as of December 31, 2022.

(3) Mr. Lister's deferred benefit from the Huntsman Pension Scheme (U.K.) is based on his employment with us while he was in the United Kingdom between August 29, 1995 and April 30, 2008. His U.K. benefit stopped accruing when his participation in the US-based plans began upon his localization in the United States on May 1, 2008.

(4) As of December 31, 2022, Mr. Hankins had served 43.4 years with our Company. The Huntsman Pension Scheme (U.K.) was frozen to new participants and years of credited service ceased to accrue as of February 29, 2012. Benefits for Mr. Hankins under this plan will only increase based on changes in salary and late retirement factors to recognize that Mr. Hankins has passed the Normal Retirement Age for the Scheme.

(5) We credited Mr. Stryker with 10 years of service under the Supplemental Executive Retirement Plan when he was hired in June 2013.

In the U.S., we sponsor the Huntsman Defined Benefit Pension Plan (the "Huntsman Pension Plan"), a tax-qualified defined benefit pension plan. Effective July 1, 2004, the formula used to calculate future benefits under the Huntsman Pension Plan was changed to a cash balance formula. The benefits accrued under the plan as of June 30, 2004 were used to calculate opening cash balance accounts. Of our NEOs, Messrs. Huntsman, Lister, Stryker, and Rogers were participants in the Huntsman Pension Plan in 2022. The Huntsman Pension Plan was closed to new participants effective July 1, 2014.

The Huntsman Supplemental Executive Retirement Plan (the "Supplemental Executive Retirement Plan") is a non-qualified supplemental pension plan that provides benefits for designated executive officers based on certain compensation amounts not included in the calculation of benefits payable under the Huntsman Pension Plan. Of our NEOs, Messrs. Huntsman, Lister, Stryker, and Rogers were participants in the Supplemental Executive Retirement Plan in 2022. The compensation taken into account for these NEOs under the Supplemental Executive Retirement Plan includes amounts in excess of the qualified plan limitations. The Supplemental Executive Retirement Plan benefit is calculated as the difference between (1) the benefit determined using the Huntsman Pension Plan formula with unlimited base salary plus annual cash performance awards, and (2) the benefit determined using base salary plus annual cash performance awards as limited by federal regulations.

Both plans express benefits as a hypothetical cash balance account established in each participant's name, and a participant's account receives two forms of credits: "pay credits" and "interest credits." Pay credits equal a percentage of a participant's compensation and are credited to a participant's account on an annual basis. "Compensation" for this purpose includes both salary and annual cash performance awards. "Compensation" under the Huntsman Pension Plan is subject to the compensation limit applicable to tax-qualified plans of $305,000 for 2022. The benefit that would be available under the Huntsman Pension Plan, but for this limitation, is provided under the Supplemental Executive Retirement Plan. The applicable pay credit percentage for our NEOs

[**TABLE OF CONTENTS**](#TOC)

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

ranges between 9% and 12% depending on the participant's combined age and years of service as of the start of each plan year. The 2022 pay credits for the Huntsman Pension Plan are $36,600 for Mr. Huntsman, $32,025 for Mr. Lister, $32,025 for Mr. Stryker, and $36,600 for Mr. Rogers. The 2022 pay credits for the Supplemental Executive Retirement Plan are $647,659, $74,377, $147,884, and $104,535 for Messrs. Huntsman, Lister, Stryker, and Rogers, respectively.

"Interest credits" for a plan year are based on the 30-year U.S. Treasury yield for November of the prior year. The minimum annual interest credit rate is 5.0%. The 2022 interest credits for the Huntsman Pension Plan are $152,468, $21,101, $23,036, and $63,926 for Messrs. Huntsman, Lister, Stryker, and Rogers, respectively. The 2022 interest credits for the Supplemental Executive Retirement Plan are $756,502, $5,570, $77,946, and $27,478 for Messrs. Huntsman, Lister, Stryker, and Rogers, respectively.

Pursuant to the terms of the Huntsman Pension Plan, at termination of employment for any reason after having completed at least three years of service, a participant will receive the amount then credited to the participant's cash balance account in an actuarially equivalent joint and survivor annuity (if married) or single life annuity (if not married). Participants may also choose from other optional forms of benefit, including a lump-sum payment in the amount of the cash balance account. For participants in the prior Supplemental Executive Retirement Plan (including Mr. Huntsman), the Huntsman Pension Plan also includes a minimum benefit that guarantees that a participant's benefit will not be less than the benefit accrued under the prior formula at transition (July 1, 2004) plus the benefit attributable to pay credits, with interest credits, beginning July 1, 2004. Under the prior plan provisions, the monthly basic benefit equaled one-twelfth of 1.4% of average earnings multiplied by pension service prior to January 1, 2000, plus 1.5% of average earnings multiplied by pension service after January 1, 2000, less 50% of the Social Security benefit prorated by pension service, payable as a life annuity to the participant. The prior Supplemental Executive Retirement Plan mirrored the benefit from the Huntsman Pension Plan. For participants taking an annuity, early retirement reductions apply if retirement occurs before normal retirement age (defined as age 65 with 5 years of service) and on or after the earlier of (i) both attaining age 50 and age plus vesting service equal to 80 or more, or (ii) age 55 with 10 years of vesting service. The effect of these reductions is to reduce the annuity amount paid by 5% per year for each year beginning at age 59 until age 50 where the amount paid would be 50%. As of December 31, 2022, Messrs. Huntsman and Rogers are our only NEOs eligible for early retirement.

Vested benefits under the Supplemental Executive Retirement Plan are paid 30 days following a participant's separation from service, unless the participant is a "specified employee" for purposes of Section 409A of the Internal Revenue Code ("Section 409A"), in which case payment will be delayed for six months. Vested benefits are paid in a single cash lump sum unless the participant elects: (1) a life annuity, (2) a life annuity with payments guaranteed for 120 months, or (3) a joint and survivor annuity providing survivor benefits equal to 50% or 100% (as elected by the participant) of the annuity payable to the participant. Benefits are unvested until the earlier to occur of: (1) completion of 3 years of service, (2) termination on account of death or "Disability" or on or after attainment of "Normal Retirement Age," or (3) termination without "Reasonable Cause." Each eligible NEO is fully vested in his benefit under the Supplemental Executive Retirement Plan.

"**Disability**" under the Huntsman Pension Plan generally provides that, for a disabled participant, service and benefit accruals continue for 24 months. After 24 months, disabled participants are deemed to be terminated participants. Disability is defined as total and permanent disability, as determined by the administrator of our long-term disability plan.

"**Normal Retirement Age**" generally is retirement eligibility upon age 65 with 5 years of service under the Huntsman Pension Plan and Supplemental Executive Retirement Plan.

"**Reasonable Cause**" generally means: (1) the grossly negligent, fraudulent, dishonest or willful violation of any law or the material violation of any of our significant policies that materially and adversely affects us, or (2) the failure of the participant to substantially perform his duties.

We also sponsor retirement benefit plans in connection with our operations in the U.K. Mr. Hankins participates in the Huntsman Pension Scheme for U.K. associates in the Polyurethanes division. The Huntsman Pension Scheme (U.K.) in which Mr. Hankins participates provides a benefit of 2/3rd of final pensionable compensation.

Final pensionable compensation is notional base salary received during the 12 months prior to retirement. Normal retirement age for the Huntsman Pension Scheme (U.K.) is age 62. These benefits also include U.K. social security benefits. As of December 31, 2022, Mr. Hankins passed age 62 and is fully vested in these benefits. Late retirement benefits are calculated based on two-thirds of final pensionable compensation and actuarial factors based on the number of years after age 62. Currently, the late retirement factor is 122.2% at age 65. The Huntsman Pension Scheme (U.K.) was frozen to new participants as of February 29, 2012 and, after that date, benefits for current participants under the plan will only increase based on changes in salary.

In addition, Mr. Lister has a deferred benefit in the Huntsman Pension Scheme (U.K.) from his period of employment with us in the United Kingdom between August 29, 1995 and April 30, 2008. He localized to the United States within our Polyurethanes division on May 1, 2008. The deferred benefit is calculated upon the U.K. departure date and is based on Mr. Lister's pensionable service and final pensionable salary on April 30, 2008. In line with the Huntsman Pension Scheme (U.K.) rules and statutory requirements, a

63 HUNTSMAN 2023 PROXY

[**TABLE OF CONTENTS**](#TOC)

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

deferred pension must be revalued through to the normal retirement age of 62. Calculated as part of the Huntsman Pension Scheme (U.K.) benefit, the plan recognizes an additional stop-gap pension payment between the normal retirement age of 62 and Mr. Lister's State Pension Age of 67. As of December 31, 2022, Mr. Lister's additional payment was calculated at $2,066 per year.

NONQUALIFIED DEFERRED COMPENSATION IN 2022

We provide executive officers based in the United States the opportunity to participate in two defined contribution savings plans: (1) a salary deferral plan (the "401(k) Plan"); and (2) a supplemental savings plan (the "Supplemental Savings Plan"). The 401(k) Plan is a tax-qualified broad-based employee savings plan; employee contributions up to 25% of base salary and annual cash performance awards are permitted up to dollar limits established annually by the Internal Revenue Service ("IRS"). The Supplemental Savings Plan is a nonqualified salary deferral plan and allows designated executive officers to defer up to 75% of eligible salary and up to 75% of annual cash performance awards. The Supplemental Savings Plan also provides benefits for participants in the form of company matching contributions based on certain compensation amounts not included in the calculation of benefits payable under the 401(k) Plan because of limits under federal law on compensation ($305,000 in 2022). As required by Section 409A, deferrals must be elected in the calendar year preceding the year in which the compensation deferred is earned. Messrs. Stryker and Rogers did not defer any earnings into the Supplemental Savings Plan in 2022.

Executive officers were previously offered the opportunity to participate in the supplemental executive money purchase pension (the "SEMPP"), a non-qualified plan that provided benefits not allowed under our money purchase pension plan (the "MPP") due to IRS compensation and allocation limits. The MPP was a tax-qualified broad-based employee savings plan that was merged into our 401(k) Plan on October 15, 2014. Contributions under the SEMPP and the MPP ceased September 1, 2014; however, some of our NEOs still maintain a balance in the SEMPP, which is reflected in the table below.

The table below provides information on the nonqualified deferred compensation of the NEOs in 2022 under the Supplemental Savings Plan and the SEMPP. The NEOs cannot withdraw any amounts from their nonqualified deferred compensation balances for a period of six months following the date of their termination of employment or retirement. No withdrawals or distributions were made in 2022.

(1) These contributions represent deferrals under the Supplemental Savings Plan and are included in the Salary column of the Summary Compensation Table for 2022 set forth above.

(2) These amounts represent contributions to our Supplemental Savings Plan and are included in the "All Other Compensation" column of the Summary Compensation Table for 2022 set forth above.

(3) No above market or preferential earnings are provided under our nonqualified defined contribution plans because the investment choices available under such plans are virtually identical to the investment choices available in the 401(k) Plan, which is a qualified plan. Consequently, none of the earnings reported in this table are included in the Summary Compensation Table set forth above.

(4) Amounts reflected in this column for each NEO who participates in the plans were previously reported as compensation to the executive officer in the Summary Compensation Table as follows: Mr. Huntsman—$3,850,254, Mr. Hankins—$1,349,561, Mr. Stryker—$51,100, and Mr. Rogers—$147,757. We ceased contributions to the SEMPP as of August 31, 2014.

(5) This amount includes a matching contribution of $8,300 and a 6% nondiscretionary contribution of $323,829 to the Supplemental Savings Plan.

(6) This amount includes $3,173,939 from our Supplemental Savings Plan and $11,001,754 from the SEMPP.

(7) This amount includes a matching contribution of $1,114 and a 6% nondiscretionary contribution of $49,585 to the Supplemental Savings Plan.

(8) This amount includes $355,967 from our Supplemental Savings Plan and $50,141 from the SEMPP.

(9) This amount includes a matching contribution of $81,514 and a 6% nondiscretionary contribution of $122,271 to the Supplemental Savings Plan.

(10) This amount includes $4,188,540 from our Supplemental Savings Plan and $846,160 from the SEMPP.

(11) This amount includes a matching contribution of $8,300 to the Supplemental Savings Plan.

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

(12) This amount is comprised of $81,817 from our Supplemental Savings Plan.

(13) This amount includes a matching contribution of $8,300 and a 6% nondiscretionary contribution of $52,267 to the Supplemental Savings Plan.

(14) This amount includes $493,676 from our Supplemental Savings Plan and $298,028 from the SEMPP.

The Supplemental Savings Plan provides for payment of benefits to a participant upon the earlier to occur of a "Change of Control" or a termination of the participant's service. Benefits paid upon a "Change of Control" are paid in a single lump sum payment. Benefits payable upon a separation from service can be made (at the election of the participant) in either a single lump sum payment or in substantially equal installments over a period selected by the participant that does not exceed 10 years. In addition, the participant may request distribution of all, or a portion of, the amounts credited to his account upon an "Unforeseeable Emergency." Payments upon separation from service will be delayed six months in accordance with Section 409A in the event a participant is a "specified employee" for purposes of Section 409A. The Supplemental Savings Plan was amended on September 1, 2014 to increase the eligible match to 4% of pay. Additionally, for individuals who had been participants in the MPP or SEMPP plans, we provide a 6% non-discretionary contribution to the Supplemental Savings Plan. This non-discretionary contribution was implemented to offset the effect of discontinuation of all contributions to the MPP and SEMPP plans effective August 31, 2014. Mr. Stryker is not eligible to receive the 6% non-discretionary contribution because he is a participant in the Huntsman Defined Benefit Pension Plan.

The Supplemental Savings Plan defines a "Change of Control" as the occurrence of either of the following events:

• Any person becomes the owner of 35% or more of our outstanding voting stock (other than certain persons affiliated with us).

• The replacement of a majority of the Board over a two-year period except in cases where (1) such replacement is not approved by a vote of at least a majority of the incumbent Board or (2) the election or nomination of such replacement Board members is by certain of our affiliates.

In addition, any "Change of Control" must also constitute a change in control for purposes of Section 409A.

A participant will be deemed to have incurred an "Unforeseeable Emergency" if the participant suffers a severe financial hardship resulting from (1) an illness or accident with respect to the participant, the participant's spouse or a dependent, (2) the loss of property due to casualty or (3) other similar extraordinary and unforeseeable circumstances arising as a result of events beyond the participant's control determined by us to constitute an unforeseeable emergency for purposes of Section 409A.

The SEMPP was a nonqualified plan for senior executives that provided for benefits not allowed under the MPP due to IRS compensation and allocation limits. Employees are vested in this account upon meeting 10 years of service, upon attaining normal retirement age, death or disability, or upon termination of employment without reasonable cause. Effective September 1, 2014, we no longer make contributions to the SEMPP.

The plan provides for the payment of vested benefits upon a participant's separation from service except to the extent the participant is a "specified employee" for purposes of Section 409A in which case benefits will be delayed six months. A participant's benefits vest on the earlier to occur of (1) completion of 10 years of service, (2) termination on account of death, "Disability," or on or after attainment of "Normal Retirement Age," or (3) termination without "Reasonable Cause." "Disability," "Normal Retirement Age," and "Reasonable Cause" have the same meanings as set forth above in our description of the Supplemental Executive Retirement Plan under "—Pension Benefits in 2022," except that a "Disability" must also constitute a disability for purposes of Section 409A. Each of Messrs. Huntsman and Hankins is currently vested in his SEMPP benefit. Benefits are payable in one of the following forms elected by a participant:

• A single lump-sum payment;

• A single life annuity;

• A joint and survivor annuity; or

• Installments over a period selected by the participant not in excess of 10 years.

Participants are entitled to elect the investment of their accounts under both the Supplemental Savings Plan and the SEMPP. Although no assets may actually be invested, a participant's benefit value is based on the gains or losses of the investments they choose. No above market or preferential earnings are provided under our nonqualified defined contribution plans because all but one of the investment choices available under the plans are identical to the investment choices available in the 401(k) Plan. In the case of the investment choice not available in the 401(k) plan, the investment is a publicly available insured fixed rate product which the rate of return is pre-determined by the insurance provider for a prospective 12-month period. Consequently, none of the earnings reported in the "Nonqualified Deferred Compensation in 2022" table above are included in the Summary Compensation Table for 2022. Participants may change their investment options at any time by contacting the plan record keeper.

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE-IN-CONTROL

Our NEOs may receive compensation in connection with an involuntary termination of employment or a change of control pursuant to the terms of the following arrangements:

• the Executive Severance Plan (in the case of the NEOs other than Mr. Huntsman);

• the Severance Agreement with Mr. Huntsman (as amended);

• the 2016 Huntsman Stock Incentive Plan and the Stock Incentive Plan as amended and restated effective May 8, 2014 (the "Prior Stock Incentive Plan"); and

• other existing plans and arrangements in which our NEOs participate.

#### Executive Severance Plan.
Through our Executive Severance Plan, which was amended and restated by the Board of Directors on February 19, 2020 (the "Executive Severance Plan"), we provide our executive officers, including our NEOs, certain payments and benefits upon a termination without Reasonable Cause or upon a termination by the executive for Good Reason (each, a "Qualifying Termination"). In the event of a Qualifying Termination, our NEOs are entitled to the following payments and benefits: (i) a lump sum cash payment equal to two times Base Compensation, (ii) continuation of medical benefits for U.S. participants for up to 18 months following termination (which will be in the form of a lump sum cash payment equal to the COBRA premium at the time of departure multiplied by the severance period multiplied by 100%), (iii) outplacement services for a period of one year or until the participant obtains substantially comparable employment, if earlier, and (iv) a Pro-Rata Annual Bonus paid on the date that annual bonuses are paid to similarly situated participants, but in no event later than March 15 of the calendar year following the calendar year in which the Qualifying Termination occurs. The level of severance is evaluated each year.

"**Base Compensation**" generally means the annualized base salary of the participant in effect at termination of employment, plus the target annual bonus for the year in which the termination of employment occurs.

"**Pro-Rata Annual Bonus**" generally means actual bonus amount, prorated based on the number of days employed by the employer during the year of termination, payable to the participant for a given calendar year pursuant to the employer's cash performance bonus program as in effect from time to time.

"**Reasonable Cause**" generally means: (1) the grossly negligent, fraudulent, dishonest, or willful violation of any law or the material violation of any of our significant policies that materially and adversely affects us, or (2) the failure of the participant to substantially perform the participant's duties.

"**Good Reason**" generally means a voluntary termination of employment by the participant as a result of (1) a materially detrimental reduction or change to the job responsibilities or in the current base compensation of the participant, or (2) within a period of 12 months following a Change of Control, changing the participant's principal place of work by more than 50 miles, in each case, which is not remedied by our Company within 30 days after receipt of notice.

A "**Change of Control**" is defined pursuant to the 2016 Huntsman Stock Incentive Plan and generally means the occurrence of any of the following:

• An acquisition by any person of 20% or more of the combined voting power of our outstanding voting securities.

• The consummation of a reorganization, merger, consolidation, or other transaction in which our stockholders do not own, immediately thereafter, more than 20% or more of the combined voting power of the resulting entity in substantially the same proportion as their stock ownership prior to the transaction.

• The sale or disposition of all or substantially all of our assets.

• A majority change in the incumbent directors of the Board.

• An approval by the Board or our stockholders of a complete or substantially complete liquidation or dissolution.

A participant is not entitled to benefits under the Executive Severance Plan if the participant is reemployed with an employer in our controlled group, if the participant refuses to sign a waiver and release of claims in our favor if requested, if the participant is entitled to severance benefits under a separate agreement or plan maintained by us, or if the Executive Severance Plan's administrator determines the participant has violated any of the restrictive covenants set forth in the Executive Severance Plan.

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

Our Executive Severance Plan includes restrictive covenants, including perpetual confidentiality and non-disparagement covenants and non-competition and non-solicitation of employees and customers covenants that apply during the term of the participant's employment and for 12 months following termination.

#### Severance Agreement with Mr. Huntsman.
On February 19, 2020, we and Mr. Huntsman entered into an amended and restated CEO Severance Agreement. The CEO Severance Agreement is designed to provide severance benefits following a qualifying termination of employment. During the term of this agreement, Mr. Huntsman is not eligible to participate in the Executive Severance Plan.

Pursuant to the CEO Severance Agreement, if Mr. Huntsman is terminated (i) by us other than for Reasonable Cause or (ii) by Mr. Huntsman for Good Reason, Mr. Huntsman will be entitled to the same payments and benefits specified above in the Executive Severance Plan, as well as (i) accrued annual base salary, (ii) any earned but unpaid annual bonus, and (iii) any accrued but unused vacation pay through the date of termination (collectively, the "Accrued Obligations").

In the event Mr. Huntsman's employment is terminated by us other than for Reasonable Cause or by him for Good Reason, in either case, *within two years following a change of control*, we will pay him (a) a lump sum cash amount equal to 2.9 times his then current Base Compensation, (b) Pro-Rata Annual Bonus paid on the date that annual bonuses are paid to similarly situated executives, but in no event later than March 15 of the calendar year following the calendar year in which the termination occurs, (c) the continuation of medical benefits for Mr. Huntsman for up to 18 months following termination (which will be in the form of a lump sum cash payment equal to the COBRA premium at the time of departure multiplied by the severance period multiplied by 100%), and (d) the Accrued Obligations.

Payment of any amounts described above (other than the Accrued Obligations) is contingent upon Mr. Huntsman executing (and not revoking) a release of claims in favor of Huntsman. The CEO Severance Agreement does not contain tax gross up provisions; however, the agreements do include a "best of net" provision, which provides that, if any payments or benefits to which Mr. Huntsman is entitled in connection with his termination are likely subject to the tax imposed by Section 4999 of the Internal Revenue Code, the payment will (1) be reduced such that Section 4999 does not apply or (2) paid in full, whichever produces the better net after tax position to Mr. Huntsman.

The CEO Severance Agreement utilizes the same definitions of Base Compensation, Pro-Rata Annual Bonus, and Reasonable Cause as set forth above with respect to our Executive Severance Plan. A termination for Good Reason pursuant to the CEO Severance Agreement generally means voluntary termination of employment as a result of (1) the significant detrimental reduction or change to Mr. Huntsman's job responsibilities or in his current base compensation, or (2) a change in Mr. Huntsman's principal place of work by more than 50 miles from his principal place of work, which is not remedied by us within 30 days after receipt of notice.

For purposes of the CEO Severance Agreement, a "change of control" generally means (1) an acquisition of beneficial ownership by an individual, entity, or group of 20% or more of our then outstanding shares of common stock or of our outstanding voting securities (subject to certain exceptions), (2) a majority change in the incumbent directors of the Board, (3) the consummation of a reorganization, merger or consolidation or sale or other disposition of all or substantially all of our assets (subject to certain limitations), or (4) a complete liquidation or dissolution of Huntsman.

The CEO Severance Agreement includes customary restrictive covenants, including perpetual confidentiality and non-disparagement covenants and non-competition and non-solicitation of employees and customers covenants that apply during the term of Mr. Huntsman's employment and for 12 months following termination.

***Other Arrangements.*** As more fully described under "—Pension Benefits in 2022" above, our executives are entitled to payments pursuant to the terms and conditions of the Huntsman Pension Plan or local variants and the Supplemental Executive Retirement Plan. In addition, pursuant to our Supplemental Savings Plan, upon a change of control (as defined in the Supplemental Savings Plan), participants, including the NEOs, may elect to receive the present value of the benefits payable to them under this plan. Amounts payable under the Supplemental Savings Plan and SEMPP are described under "—Nonqualified Deferred Compensation in 2022" above. As described under "—Pension Benefits in 2022" above, pursuant to the Huntsman Pension Scheme (U.K.), Mr. Hankins is entitled to receive annual benefits of <sup>2</sup>∕3 of pensionable compensation.

Upon a qualifying disability, Mr. Hankins' benefits would be 75% of pensionable compensation until age 65. Mr. Hankins is entitled to a minimum death benefit equal to 66.6% of the accrued benefit and a lump sum equal to eight times pensionable compensation.In addition, as a citizen of the U.K., Mr. Hankins is an entitled participant in the U.K. business severance plan. At the time of a termination, payout potential from both the Executive Severance Plan and the U.K. business plan would be considered, then the plan generating the more generous payout would be used. Mr. Hankins is entitled to 12 months' notice and U.K. statutory severance pay of $22,955. The Executive Severance Plan provides greater severance amounts than the U.K. business severance plan for Mr. Hankins in the event of a termination without "Reasonable Cause" or upon a termination by the executive for "Good Reason."

In addition, an acceleration of Mr. Lister's 13,460 unvested options would have an estimated value of $75,573 on December 31, 2022.

(5) Any acceleration of vesting of long-term equity incentive awards held by Mr. Hankins requires the approval of the Compensation Committee, which we assume for purposes of this table would have occurred on December 31, 2022. An acceleration of Mr. Hankins' 48,780 unvested shares of restricted stock would have an estimated value of $1,340,474 and 101,602 target unvested performance share units would have an estimated value of $2,792,023. In addition, an acceleration of Mr. Hankins' 14,108 unvested options would have an estimated value of $83,802 on December 31, 2022.

(6) Any acceleration of vesting of long-term equity incentive awards held by Mr. Stryker requires the approval of the Compensation Committee, which we assume for purposes of this table would have occurred on December 31, 2022. An acceleration of Mr. Stryker's 34,248 unvested shares of restricted stock would have an estimated value of $941,135 and 71,971 target unvested performance share units would have an estimated value of $1,977,763. In addition, an acceleration of Mr. Stryker's 10,480 unvested options would have an estimated value of $62,251 on December 31, 2022.

(7) Any acceleration of vesting of long-term equity incentive awards held by Mr. Rogers requires the approval of the Compensation Committee, which we assume for purposes of this table would have occurred on December 31, 2022.

In addition, an acceleration of Mr. Rogers' 8,062 unvested options would have an estimated value of $47,888 on December 31, 2022.

(8) In the event of an involuntary termination following a change of control, this amount is equal to (a) 2.9 times Mr. Huntsman's Base Compensation, (b) Pro-Rata Annual Bonus, and (c) the continuation of medical benefits for Mr. Huntsman for up to 18 months following termination. See "—Severance Agreement with Mr. Huntsman."

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

Ms. Sonia Dulá and Messrs. Curtis E. Espeland, José Muñoz, Wayne A Reaud, Nolan D. Archibald and Daniele Ferrari each served on the Compensation Committee during 2022. Mr. Ferrari served as Division President, Performance Products of Huntsman Corporation from 2008 to 2011. None of the members of the Compensation Committee was an officer or employee of our Company during 2022 or had any substantial business dealings with our Company or any of its subsidiaries. None of our executive officers serves as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of the Board or the Compensation Committee of our Company.

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 about the relationship of the annual total compensation of our employees and the annual total compensation of Peter R. Huntsman, our CEO.

For 2022, our last completed fiscal year:

• The median of the annual total compensation of all employees of our Company (other than Mr. Huntsman) was $85,604; and

• The annual total compensation of Mr. Huntsman, as reported in the 2022 Summary Compensation Table included in this Proxy Statement, was $13,380,023.

• Based on this information, for 2022 the ratio of the annual total compensation of our CEO to the median of the annual total compensation of all employees was reasonably estimated to be 156 to 1.

SEC rules allow us to identify our median employee once every three years unless there has been a change in our employee population or employee compensation arrangements that we reasonably believe would result in a significant change in our pay ratio disclosure. Accordingly, our 2022 CEO pay ratio is calculated utilizing the same median employee identified in 2020. In determining that it was still appropriate to utilize our 2020 median employee for this disclosure, we considered the changes to our global employee population and compensation programs during 2022, as well as the absence of a material change in that employee's job description or compensation during 2022.

To identify the median employee in 2020, we took the following steps:

• We selected December 31, 2020, the last day of our 2020 payroll year, as the determination date for purposes of identifying the median employee.

• Our total global workforce, as of December 31, 2020, consisted of approximately 9,580 individuals working at our Company and consolidated subsidiaries.

[**TABLE OF CONTENTS**](#TOC)

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• As permitted by SEC rules, we excluded approximately 478 non-U.S. employees (representing less than 5% of our total global workforce as if December 31, 2020) from the employee pool used to determine our median employee. The table below identifies (1) the jurisdictions from which those employees were excluded and (2) the approximate number of employees in each jurisdiction.

• Our employee population, after accounting for the 5% "de minimis exemption" adjustment as described above, consisted of approximately 9,102 individuals.

• We used a consistently applied compensation measure to identify our median employee by comparing the actual non-discretionary compensation (inclusive of salaries and wages) reflected in our payroll records as reported to local tax authorities for 2020. We did not make any cost-of-living adjustments in identifying the median employee.

We combined all elements of our median employee's compensation for 2022 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S K, resulting in annual total compensation of $85,604. The difference between such employee's salary and wages and the employee's annual total compensation represents (i) the estimated value of such employee's health care benefits (estimated for the employee and such employee's eligible dependents at $5,403); (ii) contributions in the amount of $5,744 that we made on the employee's behalf to our pension plan in 2022; and (iii) $7,996 representing the estimated change in annualized value of our pension plan for our median employee.

Fuller Company, Lanxess AG, Trinseo S.A. and Westlake Chemical Corp. For information on how we use the 2022 Performance Peers, see "Compensation Discussion and Analysis—2022 Executive Compensation Decisions—Long-Term Equity Compensation".

#### PERFORMANCE MEASURES
The following tabular list provides information on the most important financial performance measures used by the registrant to link compensation actually paid to the Company's named executive officers, for the most recently completed fiscal year, to the Company's performance:

---

| |
|:---|
| **Performance Measure**  |
| Relative TSR |
| Adjusted EBITDA |
| Free cash flow |
| Optimization Program |
| EH&S compliance |

---

#### RELATIONSHIP BETWEEN CAP AND PERFORMANCE MEASURES
In the "Compensation Discussion and Analysis" section of this Proxy Statement, we provide greater detail on the elements of our executive compensation program and our pay-for-performance compensation philosophy. The values included in the columns for CAP paid to our CEO and the other NEOs, in each of the fiscal years reported above and over the three-year cumulative period shows how the compensation awarded fluctuated year-over-year, primarily based on our stock price as of the last day of the listed fiscal year, among other factors. As the values change considerably from year-to-year based on stock price performance, they further demonstrate the pay-for-performance compensation philosophy of our executive compensation program. As the table demonstrates, the compensation of our CEO and the other NEOs is higher when our stock price performs well, and lower when the stock price does not perform as well, demonstrating the clear alignment of interests of our CEO and the other NEOs and our stockholders.

CAP versus TSR. As shown in the chart below, the CEO and other NEOs' CAP values are aligned with the Company's TSR. This is due primarily to the Company's use of long-term equity incentive awards, which are tied directly to our stock price in addition to our financial performance. The chart also compares the Company's cumulative TSR and the 2022 Performance Peer's TSR.

CAP versus Net Income. As shown in the chart below, the Company's net income decreased significantly in 2022 and the CEO and other NEOs' CAP values decreased as well. This is due in large part to the significant emphasis the Company places on long-term equity incentive awards, which are sensitive to changes in stock price. These measures do not align as closely as TSR because the Company does not use net income to determine compensation levels or annual cash performance award payouts.

CAP versus adjusted EBITDA. The chart below compares the CEO and other NEOs' CAP values to our adjusted EBITDA, which indicates there is a very strong relationship between adjusted EBITDA and CAP.

Historically, adjusted EBITDA determined the largest portion of our annual cash performance awards. Because the Company used adjusted EBITDA margin in 2022, this portion of the annual cash performance award was not earned, thus showing a lower correlation in 2022.

AUDIT COMMITTEE REPORT

The Audit Committee of the Board (the "Committee") assists the Board in fulfilling its oversight responsibilities with respect to the external financial reporting process and the adequacy of Huntsman's internal controls over financial reporting and related disclosure controls and procedures, areas for which management has primary responsibility. Specific responsibilities of the Committee are set forth in the Audit Committee Charter, a copy of which can be found on Huntsman's website at *www.huntsman.com*.

The independent registered public accounting firm is responsible for expressing an opinion on the conformity of Huntsman's audited financial statements with accounting principles generally accepted in the United States and for issuing its report on Huntsman's internal control over financial reporting. All audit and non-audit services provided to Huntsman by the independent registered public accounting firm are pre-approved by the Committee or by the Chair of the Committee pursuant to delegated authority, and the Committee considers the compatibility of such non-audit services with the independent registered public accounting firm's independence.

The Committee evaluates the performance of the independent registered public accounting firm each year and determines whether to re-engage the current firm or consider other audit firms. In doing so, the Committee considers the quality of the services provided by the independent registered public accounting firm, along with their capabilities, technical expertise, and knowledge of Huntsman's operations and industry. Based on these evaluations, the Committee decided to engage Deloitte & Touche LLP as Huntsman's independent registered public accounting firm for the year ending December 31, 2023. Although the Committee has the sole authority to appoint the independent registered public accounting firm, the Committee has continued its long-standing practice of recommending that the Board ask stockholders to ratify the appointment of the registered public accounting firm at Huntsman's annual meeting of stockholders.

The Committee has reviewed and discussed Huntsman's audited financial statements for the year ended December 31, 2022 with Huntsman's management. The Committee has discussed with Deloitte & Touche LLP the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board ("PCAOB") and the SEC. The Committee has received the written disclosures and the letter from Deloitte & Touche LLP required by applicable requirements of the PCAOB regarding Deloitte & Touche LLP's communications with the Committee concerning independence, and has discussed with Deloitte & Touche LLP its independence.

Based on the review and discussions referred to in the preceding paragraph, the Committee recommended to the Board that Huntsman's audited financial statements for the year ended December 31, 2022 be included in Huntsman's Annual Report on Form 10-K for the year ended December 31, 2022.

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

PROPOSAL 2—NON-BINDING ADVISORY VOTE TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

Pursuant to Section 14A of the Exchange Act, we are submitting a proposal to our stockholders for a non-binding advisory vote to approve the compensation of our NEOs as disclosed in this Proxy Statement in accordance with the compensation disclosure rules of the SEC. This say-on-pay proposal gives our stockholders the opportunity to express their views on the compensation of our NEOs. Currently, our stockholders are given the opportunity to cast an advisory vote on this topic annually, with the next opportunity occurring in connection with our 2024 Annual Meeting.

The guiding principles of our compensation policies and decisions include aligning each executive's compensation with our Company's business strategy and the interests of our stockholders and providing incentives intended to attract, motivate and retain key executives who are important to our long-term success. We view pay for performance as a critical element of our overall executive compensation philosophy. Consistent with this philosophy, a significant portion of the total compensation for each of our NEOs is related to our earnings and to other performance factors that are intended to measure our progress against the goals of our strategic and operating plans and the long-term performance of our common stock.

When casting your advisory say-on-pay vote, we urge you to read the Compensation Discussion and Analysis section of this Proxy Statement, which discusses how our compensation design and practices are intended to reflect our compensation philosophy. The Compensation Committee and the Board believe that our compensation practices effectively implement our guiding principles.

The advisory say-on-pay vote is not intended to address any specific item of compensation, but rather the overall compensation of our NEOs and the principles, policies and practices described in this Proxy Statement. Accordingly, the following resolution is submitted for stockholder vote at the Annual Meeting:

"RESOLVED, that the stockholders of Huntsman Corporation approve, on a non-binding advisory basis, the compensation of its named executive officers as disclosed in the Proxy Statement for the 2023 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the SEC, including the Compensation Discussion and Analysis, the Summary Compensation Table and other related tables and disclosures."

Approval of this proposal requires approval by holders of a majority of the shares present (in person or represented by proxy) and entitled to vote at the Annual Meeting. Abstentions will be treated as votes against this proposal. If you are a street name stockholder and you do not provide your brokerage firm with voting instructions, your brokerage firm may not cast votes with respect to the shares that you beneficially own. Broker non-votes, if any, will have no effect on the vote.

While this vote is required by law, the result (1) will not be binding on our Company, the Board or the Compensation Committee, (2) will not overrule any decisions made by the Board or the Compensation Committee, and (3) will not require the Board or the Compensation Committee to take any specific action. Nevertheless, the Board and the Compensation Committee value the opinions of our stockholders and will carefully consider the outcome of the vote when making future compensation decisions for our NEOs. In particular, to the extent there is any significant vote against our NEOs' compensation as disclosed in this Proxy Statement, we will consider our stockholders' concerns, and the Compensation Committee will evaluate whether any actions are necessary to address those concerns.

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

PROPOSAL 3—NON-BINDING ADVISORY VOTE TO APPROVE THE PREFERRED FREQUENCY OF VOTES ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

As described in Proposal 2 above, in accordance with Exchange Act Section 14A, our stockholders are being provided the opportunity to cast an advisory vote on our executive compensation program. The advisory vote on executive compensation described in Proposal 2 above is referred to as a "say-on-pay" vote. As required by Exchange Act Section 14A, this Proposal 3 affords stockholders the opportunity to cast an advisory vote on how often we should include a say-on-pay vote in our proxy materials for future annual stockholder meetings (or a special stockholder meeting for which our company must include executive compensation information in the proxy statement for that meeting). Under this Proposal 3, stockholders may vote on a non-binding basis to have the say-on-pay vote every year, every two years, or every three years. In addition, stockholders may abstain from voting on this Proposal 3. Exchange Act Section 14A requires the company to hold an advisory vote on the frequency of the say-on-pay vote at least once every six years.

We believe that say-on-pay votes should be conducted every year so that stockholders can provide us with direct and timely input on our executive compensation program. While our executive compensation programs are designed to promote a long-term connection between pay and performance, the Board recognizes that executive compensation disclosures are made annually and holding an annual advisory vote on executive compensation provides us with more direct and immediate feedback on our compensation disclosures. However, stockholders should note that because the advisory vote on executive compensation occurs well after the beginning of the compensation year, and because the different elements of our executive compensation programs are designed to operate in an integrated manner and to complement one another, in many cases it may not be feasible or feasible to change our executive compensation programs in consideration of any one year's advisory vote on executive compensation before the following year's annual meeting of stockholders.

The proxy card provides stockholders with the opportunity to choose among four options (1 year, 2 years, 3 years, or abstain) and, therefore, stockholders will not be voting to approve or disapprove the recommendation of the Board. Approval of this proposal requires approval by holders of a majority of the shares represented in person or by proxy and entitled to vote at the Annual Meeting. Because this proposal has three possible substantive responses (1 year, 2 years or 3 years), if none of the frequency alternatives receives the vote of the holders of a majority of the shares present, then we will consider stockholders to have approved the frequency selected by holders of a plurality of the shares present. Abstentions will be treated as votes against this proposal. If you are a street name stockholder and you do not provide your brokerage firm with voting instructions, your brokerage firm may not cast votes with respect to the shares that you beneficially own. These broker non-votes will have no effect on the vote.

Please note that this vote is advisory and not binding on our company or the Board in any way. The Board and the Compensation Committee will take into account the outcome of the vote, however, when considering the frequency of future advisory votes on executive compensation. The Board may decide now or in the future that it is in the best interests of our stockholders and our company to hold an advisory vote on executive compensation on a different frequency than the frequency receiving the most votes cast by our stockholders.

#### THE BOARD RECOMMENDS A VOTE "FOR" THE OPTION OF "1 YEAR" AS THE PREFERRED FREQUENCY FOR ADVISORY VOTES ON EXECUTIVE COMPENSATION

PROPOSAL 4—RATIFICATION OF THE APPOINTMENT OF OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has appointed Deloitte & Touche LLP to serve as our independent registered public accounting firm and to audit our consolidated financial statements for the fiscal year ending December 31, 2023. Deloitte & Touche LLP has served as our auditor since 1984. The Audit Committee has been advised by Deloitte & Touche LLP that neither the firm, nor any member of the firm, has any financial interest, direct or indirect, in any capacity in us or our subsidiaries. As a matter of good corporate governance, the Audit Committee has determined to submit its selection of Deloitte & Touche LLP to stockholders for ratification.

The proposal to ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm will require approval by holders of a majority of the shares present (in person or represented by proxy) and entitled to vote at the Annual Meeting. Abstentions will be treated as votes against this proposal. If you are a street name stockholder and you do not provide your brokerage firm with voting instructions. Broker non-votes, if any, will have no effect on the vote.

If the selection of the independent registered public accounting firm is not ratified, the Audit Committee will reconsider its selection. 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 the Audit Committee believes that such a change would be in the best interest of our Company and our stockholders.

One or more representatives of Deloitte & Touche LLP are expected to attend the Annual Meeting and will be available to respond to appropriate questions and, if they desire, will have an opportunity to make a statement.

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

PROPOSAL 5: APPROVE THE SECOND AMENDED AND RESTATED CERTIFICATE OF INCORPORATION

The State of Delaware, which is our state of incorporation, recently enacted legislation that enables Delaware companies to limit the liability of certain of their officers in limited circumstances. In light of this update, we are proposing to amend and restate our Certificate of Incorporation to add a provision exculpating certain of our officers from liability in specific circumstances, as permitted by Delaware law (the "Second Amended and Restated Certificate of Incorporation"). The new Delaware legislation only permits, and our proposed Second Amended and Restated Certificate of Incorporation would only permit, exculpation of certain officers in connection with direct claims brought by stockholders, including class actions, but would not eliminate officers' monetary liability for breach of fiduciary duty claims brought by the Company itself or for derivative claims brought by stockholders in the name of the Company. In addition, it would not apply to breaches of the duty of loyalty, acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, or any transaction in which the officer derived an improper personal benefit. The rationale for so limiting the scope of liability is to strike a balance between stockholders' interest in accountability and their interest in our Company being able to attract and retain quality officers to work on its behalf.

The Governance Committee believes that there is a need for directors and officers to remain free of the risk of financial ruin as a result of an unintentional misstep. Further, the Governance Committee noted that the proposed provision would not negatively impact stockholder rights. Therefore, taking into account the narrow class and type of claims for which officers' liability would be exculpated, and the benefits the Governance Committee believes would accrue to our Company and its stockholders in the form of an enhanced ability to attract and retain talented officers, the Governance Committee recommended to the Board the Second Amended and Restated Certificate of Incorporation to provide such exculpation to the extent permitted by Delaware law. Based on this recommendation, the Board determined that it is in the best interests of our Company and our stockholders to approve the Second Amended and Restated Certificate of Incorporation as described herein. The Second Amended and Restated Certificate of Incorporation also makes certain immaterial changes to provide for a new agent for service and remove material regarding the declassification of our Board, which was completed in 2017.

The general description of the proposed amendments set forth above is qualified in its entirety by reference to the Second Amended and Restated Certificate of Incorporation, which is attached as Appendix A.

If the proposed Amendments are approved, they will become effective upon the filing of a restated certificate of incorporation with the Delaware Secretary of State, which we intend to do promptly following the Annual Meeting.

Accordingly, we ask our stockholders to vote on the following resolution:

"RESOLVED, that the Huntsman's stockholders approve the Second Amended and Restated Certificate of Incorporation to, among other things, add a new Article X, which shall read in its entirety as follows:

#### ARTICLE X LIMITED LIABILITY OF OFFICERS
An officer shall not be personally liable to the Company or its stockholders for monetary damages for breach of fiduciary duty as an officer, except, if and to the extent required by the DGCL, as amended from time to time, for liability (i) for any breach of the officer's duty of loyalty to the Company or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for any transaction from which the Director derived an improper personal benefit or (iv) in any action by or in the right of the Company. Neither the amendment nor repeal of this Article X shall eliminate or reduce the effect of this Article X in respect of any matter occurring, or any cause of action, suit or claim that, but for this Article X, would accrue or arise, prior to such amendment or repeal."

Approval of this proposal requires approval by the holders of a majority of the shares of our common stock issued and outstanding and entitled to vote thereon. Abstentions will be treated as votes against this proposal. If you are a street name stockholder and you do not provide your brokerage firm with voting instructions, your brokerage firm may not cast votes with respect to the shares that you beneficially own. Broker non-votes, if any, will be treated as votes against this proposal. If our stockholders approve this proposal, our proposed Second Amended and Restated Certificate of Incorporation will become effective upon our Second Amended and Restated Certificate of Incorporation being filed with the Delaware Secretary of State, which we anticipate doing as soon as practicable following stockholder approval. If our stockholders do not approve this proposal, the Second Amended and Restated Certificate of Incorporation will not be filed with the Delaware Secretary of State and our Amended and Restated Certificate of Incorporation will remain in effect.

#### The Board unanimously recommends a vote "FOR" the proposal to approve the Second Amended and Restated Certificate of Incorporation.

PROPOSAL 6—STOCKHOLDER PROPOSAL REGARDING SHAREHOLDER RATIFICATION OF EXCESSIVE TERMINATION PAY

The following stockholder proposal has been submitted to us for action at the Annual Meeting by John Chevedden. This proposal will be voted on at the Annual Meeting only if properly presented by or on behalf of Mr. Chevedden. In accordance with applicable proxy regulations, Mr. Chevedden's proposed resolution and supporting statement are set forth below in the form that we received them, with the graphic added at his request:

#### Shareholder Ratification of Excessive Termination Pay
![[MISSING IMAGE: ic_sharehold-4c.jpg]](ic_sharehold-4c.jpg)

Shareholders request that the Board seek shareholder approval of any senior manager's new or renewed pay package that provides for severance or termination payments with an estimated value exceeding 2.99 times the sum of the executive's base salary plus target short-term bonus.

"Severance or termination payments" include cash, equity or other pay that is paid out or vests due to a senior executive's termination for any reason. Payments include those provided under employment agreements, severance plans, and change-in-control clauses in long-term equity plans, but not life insurance, pension benefits, or deferred pay earned and vested prior to termination.

"Estimated total value" includes: lump-sum payments; payments offsetting tax liabilities, perquisites or benefits not vested under a plan generally available to management employees, post-employment consulting fees or office expense and equity awards if vesting is accelerated, or a performance condition waived, due to termination.

The Board shall retain the option to seek shareholder approval after material terms are agreed upon.

Generous performance-based pay can sometimes be justified but shareholder ratification of "golden parachute" severance packages with a total cost exceeding 2.99 times base salary plus target short-term bonus better aligns management pay with shareholder interests.

For instance at one company, that does not have this policy, if the CEO is terminated he could receive $44 million in termination pay—over 10 times his base salary plus short-term bonus. In the event of a change in control, the same person could receive a whopping $124 million in accelerated equity payouts even if he remained employed.

It is especially important that this excessive pay type situation be avoided at Huntsman since management pay was rejected by 15% of shares in 2022 when a 5% rejection is often the norm at well performing companies. A 15% rejection is all the worse since the Huntsman stock is a poor performer compared to its $34 price in 2018.

Shareholder Ratification of Excessive Termination Pay received between 51% and 65% support at:

FedEx (FDX)

Spirit AeroSystems (SPR)

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

#### BOARD OF DIRECTORS' STATEMENT IN OPPOSITION
The Board of Directors has carefully considered this proposal and concluded the adoption of this proposal is not only unnecessary, but also not in the best interest of the Company and its stockholders.

Huntsman's Board of Directors therefore unanimously recommends a vote "AGAINST" Proposal 6 (the "Proposal") for the following reasons:

As disclosed elsewhere in this Proxy Statement, we maintain strong governance policies and practices including with respect to post-termination compensation of executive officers. The following discussion highlights these policies and practices, including the fact that ***we already adopted a policy prohibiting cash severance payments exceeding 2.99 times base salary and annual bonus without stockholder approval***. As such, the Board believes the limitations imposed under the Proposal are unnecessary in light of our existing policies and practices and would unduly restrict our ability to remain competitive with our peers and to design appropriate pay packages and address specific circumstances as needed.

 **As fully disclosed in our Proxy Statement, Huntsman already has a carefully tailored policy to limit cash severance payments of executive officers in excess of 2.99 times base salary and annual target bonus without stockholder approval.** 

Our Severance Compensation Policy was recently adopted by the Board and reflects our long-standing approach on executive termination pay. The Severance Compensation Policy requires Huntsman to seek stockholder approval before paying certain types of cash severance benefits that would exceed 2.99 times the sum of the executive officer's base salary and annual target bonus—the very same ratio that the Proposal contemplates. The Board believes that our Severance Compensation Policy, which is more carefully tailored than the overly broad Proposal, coupled with our existing severance plans, strike the right balance between shareholder rights and being able to be competitive in the market for talent. Any new or amended employment agreement, severance agreement or similar arrangement with any of our executive officers, and any new or amended severance plans or policies will not permit for cash severance benefits exceeding 2.99 times the sum of the executive officer's base salary and annual target bonus without first seeking stockholder approval of such payment.

The existing policy includes the following specific features: (i) it allows certain exclusions to the types of compensation subject to the policy, such as payments of salary or bonus amounts that had accrued at the time of termination, and (ii) it applies to a clearly defined set of Huntsman officers whose compensation is already disclosed to shareholders under SEC rules (as opposed to "any senior manager," an undefined and potentially very broad population of employees, as contemplated by the Proposal). As a result, the current policy enables Huntsman to offer applicable post-termination benefits in situations we believe are appropriate, such as upon termination of Huntsman employment in connection with our transfer of a business operation to a successor employer. This is a scenario where we believe acceleration of equity vesting is appropriate and should not be subject to specific shareholder approval beyond the general say-on-pay advisory vote that we hold annually.

The Proposal warns abstractedly about an executive officer who may receive "over 10 times his base salary plus short-term bonus," suggesting we may have such termination packages without identifying a single instance thereof. In point of fact, our existing executive severance plans in which our executive officers participate generally provide for much lower levels of cash severance payments than the Severance Compensation Policy permits. For more information regarding the payments that are provided for under these severance plans, please see "Part 5—Executive Compensation—Potential Payments Upon Termination or Change-In-Control" on page 66 of the Proxy Statement.

#### The Proposal's limits on equity compensation go too far.
The Proposal seeks to restrict the acceleration of vesting of equity awards in connection with a termination of service by including the value of this benefit in the amount of "severance or termination payments" to be applied against the limit. However, our stockholders have already voted on and given the Board the ability to accelerate vesting of equity awards under our Stock Incentive Plans, which we believe indicates that stockholders recognize that the Board needs the flexibility to design appropriate pay packages and address specific circumstances, as further outlined below.

*Our stockholders approved equity compensation plans that allows for acceleration of outstanding equity awards in certain circumstances related to a change in control or death or disability.* 

Huntsman's Stock Incentive Plans, which have been widely approved by our stockholders, permit the acceleration of outstanding equity awards in connection with a change in control. The Board believes that the possibility of providing this change in control severance benefit encourages executive officers to remain with Huntsman during a potential change in control, which further aligns their interests with those of our stockholders when evaluating any such potential transaction.

[**TABLE OF CONTENTS**](#TOC)

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

*The Proposal could create increased risk for stockholders and create a misalignment between our executives and our stockholders during a change-in-control transaction.* 

Without this incentive to retain executive officers during a potential change in control, our ability to deliver maximum stockholder value in such a transaction could be impaired. The Proposal would significantly limit the Board's flexibility to provide reasonable assurance to our executive officers that they could realize the full expected value of their previously granted equity awards even if a change-of-control transaction were completed. The risk of job loss following a change in control, coupled with a limit on the value that may be realized from previously granted equity awards, may present an unnecessary distraction for our executive officers and could lead them to begin seeking new employment while a transaction is being negotiated or pending.

Huntsman's Stock Incentive Plans were designed to avoid distractions and potential conflicts of interest that could otherwise arise when a potential change-in-control transaction is being considered. They permit our leadership team to remain focused on protecting stockholder interests and maximizing stockholder value. If the potential change-of-control transaction is in the best interests of our stockholders, our executive officers should be motivated to focus their full energy on pursuing this alternative, even if it is likely to result in the termination of their employment.

*By including long-term equity incentive awards in the calculation of the proposed limit on "severance or termination benefits," the Proposal discourages the use of long-term equity incentive awards, which are tied to maximizing long-term stockholder value and help us to recruit and retain executive talent.* 

The Proposal would potentially trigger a stockholder approval requirement in order for our executive officers to realize the full value of their previously granted equity awards upon death, disability or retirement, which are described on page 63 of this Proxy Statement. Since calling a special meeting of stockholders to obtain stockholder approval of such accelerated vesting would be expensive and impractical, the Board believes the Proposal would have the effect of discouraging the use of long-term equity incentive awards and would directly conflict with the objectives of our executive compensation program. It could also have an adverse impact on our ability to recruit and retain executive talent, as it would put us at a competitive disadvantage against other companies who do not face similar restrictions or uncertainty regarding their ability to offer termination protection.

Our long-term incentive compensation is designed to focus our executive officers on increasing stockholder value and to incentivize their contribution to our long-term growth and performance. The use of equity ensures that the amount of long-term incentive compensation granted is tied directly to both increases in stockholder value and the achievement of critically important multi-year performance objectives. Because its value is tied to our stock price, the executive officer's long-term incentive compensation strongly supports the objectives of ensuring that pay is aligned with changes in stockholder value and creating commonality of interest between our executive officers and stockholders. Due to the multi-year performance and/or vesting requirements, all of our long-term incentives support the goal of retaining our executive officers. Equity awards comprise a significant portion of our executive officers' total compensation and are granted and accepted with the expectation that the executive officers will be given a fair opportunity to realize the full value of these awards.

#### The Proposal's broad approach would place Huntsman at a competitive disadvantage by limiting Huntsman's ability to attract and retain executive talent.
The Board believes the Proposal would adversely affect our ability to attract executive-officer-level talent, for which we compete globally with other companies. The sort of severance benefits that would be covered by the policy this Proposal requests often arise in the context of negotiating an employment agreement with an external hire for an executive officer leadership position, particularly when a sign-on or similar one-time equity award is part of the overall compensation package necessary to induce the individual to leave a successful and well-compensated role at another company. As a result, implementing the Proposal may interfere with our ability to make binding offers of employment, including for roles that can have significant impact on our performance and results. Requiring sign-on packages for "any senior manager" to be approved by stockholders would not allow us to be nimble and competitive in the recruiting process, and candidates would not be willing to have their hiring be subject to a subsequent stockholder approval. Similar dynamics can exist in developing packages to retain employees. The delay, uncertainty and expense of seeking stockholder approval in such circumstances demonstrate the impracticality of this Proposal.

Unsurprising given the undue limitations and negative consequences that could accompany the policy requested by this Proposal, none of the other companies in Huntsman's compensation peer group disclose having this type of policy. Adopting the broad approach this Proposal suggests would disadvantage Huntsman relative to our peers in our ability to recruit and retain the best available executive talent.

#### The Proposal is unnecessary because stockholders already have opportunities to express their approval of our post-termination compensation policies.
Our existing plans and policies governing post-termination compensation for executive officers are fully described in our Proxy Statement each year under "*Part 5—Executive Compensation—Potential Payments Upon Termination or Change-In-Control"* and,

as such, stockholders have the opportunity to address those practices through our annual advisory vote on executive compensation. In addition, in the event of any merger, acquisition or other similar event, stockholders would have a further opportunity to express their views on any compensation to our named executive officers in connection with that transaction. In sum, our Board believes that our current executive compensation policies and practices, including our plans and policies governing post-termination compensation, are reasonable, appropriate and effectively align the interests of our executive officers with those of our stockholders. Adoption of this Proposal could create a misalignment between those interests and prevent us from effectively recruiting, motivating and retaining critical talent, and therefore would not be in the best interests of our stockholders.

For the foregoing reasons, the Board unanimously believes that this Proposal is not in the best interests of Huntsman or our stockholders, and recommends that you vote "AGAINST" Proposal 6.

#### THE BOARD RECOMMENDS VOTING ON THE PROXY CARD "AGAINST" THIS PROPOSAL TO REQUIRE STOCKHOLDER RATIFICATION OF EXECUTIVE TERMINATION PAYMENTS

<br> **ADDITIONAL INFORMATION** 

<br> SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table presents information regarding beneficial ownership of our common stock as of February 27, 2023 by:

• each person who we know owns beneficially more than 5% of our common stock;

• each of our directors and nominees;

• each of our NEOs; and

• all of our executive officers and directors as a group.

Under the regulations of the SEC, shares are generally deemed to be "beneficially owned" by a person if the person directly or indirectly has or shares voting power or investment power (including the power to dispose) over the shares, whether or not the person has any pecuniary interest in the shares, or if the person has the right to acquire voting power or investment power of the shares within 60 days, including through the exercise of any option, warrant or right. In accordance with the regulations of the SEC, in computing the number of shares of common stock beneficially owned by a person and the percentage ownership of such person, we deemed to be outstanding all shares of common stock subject to options or other rights held by the person that are currently exercisable or exercisable within 60 days of February 27, 2023. We did not deem such shares outstanding, however, for the purpose of computing the percentage ownership of any other person.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

#### POLICIES AND PROCEDURES
Effective February 1, 2007, as amended, the Board adopted a Related Party Transactions Policy, which includes the procedures for review, approval and monitoring of transactions involving our company and "related persons" (directors, executive officers, stockholders owning five percent or greater of our common stock, or their respective immediate family members). The policy covers any transaction involving amounts exceeding $120,000 in which a related person has or will have a direct or indirect material interest.

The Compensation Committee reviews and approves all compensation paid to family members of directors and our CEO. All other related person transactions must be approved in advance by the Audit Committee, which will approve the transaction only if it determines that the transaction is in, or is not inconsistent with, the interests of the Company and its stockholders. In evaluating the transaction, the Audit Committee will consider all relevant factors, including as applicable (1) the benefit to us in entering into the transaction; (2) the alternatives to entering into a related person transaction; and (3) whether the transaction is on terms comparable to those available to third parties.

If a director is involved in the transaction, he or she will be recused from all discussions and decisions about the transaction. The transaction must be approved in advance of its consummation. The Audit Committee will periodically monitor the transaction to ensure that there are no changed circumstances that would render it advisable, or not inconsistent with such circumstances, to amend or terminate the transaction and will review the transaction annually to determine whether it continues to be in our interests.

The Compensation Committee approved the 2022 compensation decisions described below and will continue to monitor such arrangements as consistent with our Related Party Transactions Policy.

#### HUNTSMAN FAMILY EMPLOYMENT
The following table shows compensation paid to members of the Huntsman family (other than NEOs and directors as disclosed herein) for services as officers or employees in fiscal 2022 that involve amounts exceeding $120,000. All amounts paid in 2022 were approved in advance by the Compensation Committee, which reviews and approves all annual and other compensation arrangements and components for corporate and executive officers and their family members who are employees.

HUNTSMAN CORPORATION: PROXY STATEMENT <br>

 **Appendix B <br>** 

<br> **RECONCILIATION OF NON-GAAP <br> FINANCIAL MEASURES** 

<br> The 2023 Proxy Statement includes information on adjusted EBITDA, adjusted EBITDA margin and free cash flow that does not conform to US generally accepted accounting principles ("GAAP") and are considered non-GAAP measures.

Management uses adjusted EBITDA to measure the operating performance of our business and for planning and evaluating the performance of our business segments. We believe that net income (loss) is the performance measure calculated and presented in accordance with GAAP that is most directly comparable to adjusted EBITDA.

Management internally uses a free cash flow measure: (a) to evaluate our liquidity, (b) evaluate strategic investments, (c) plan stock buyback and dividend levels and (d) evaluate our ability to incur and service debt.

(Dollars in millions)
