LETTER FROM OUR CEO AND CHAIRMAN
AND OUR LEAD INDEPENDENT DIRECTOR
AND NON-EXECUTIVE VICE CHAIR
​
DEAR FELLOW STOCKHOLDERS:
​
On behalf of the Huntsman Corporation Board of Directors, we are pleased to invite you to attend the 2026 Annual Meeting of Stockholders, which will be held virtually on Wednesday, April 29, 2026, at 8:00 a.m. Central Time.
Together, as your CEO and Chairman and your Lead Independent Director and Non-Executive Vice Chair, it is our privilege to update you on the progress the Company has made over the past year. 2025 was a challenging year. We saw troubling signs in early 2025 that the North American housing and durable goods markets were going to languish more than we expected, which required our Company to quickly pivot our initial operating plans for the year. We took quick and decisive decisions to focus on working capital, managing inventories, and capital expenditures. These conditions rippled across Europe and Asia where we again took early decisions to counter these conditions. We also accelerated our restructuring and asset rationalization through 2025 to help offset the difficult environment. By year end, we generated one of the highest free cash flows to EBITDA conversion amongst our peer group. We are confident that the actions taken in 2025 will position Huntsman for success as market conditions improve.
Cash generation and cost control were among our top priorities during 2025. We delivered strong cash performance, generating approximately $298 million of cash flow from operations and $125 million of free cash flow1 through disciplined working capital management and decisive actions to generate cash as we recognized the challenging market landscape. We also made a tremendous effort to control our costs and improve the competitiveness of our businesses. In 2025, we executed cost realignment and restructuring initiatives, achieving approximately $100 million of annualized run rate savings through multiple programs and site consolidations.
We remain focused on returning value to our stockholders and creating value through disciplined investments. In 2025, we distributed approximately $146 million in dividends to stockholders. Our Board made the difficult decision after much deliberation to reduce the dividend in the third quarter of 2025 to allow us to preserve our balance sheet through an extended cyclical trough, while continuing to return value to our stockholders. We are proud to say that the dividend paid in the fourth quarter of 2025 marked the 76th consecutive quarterly dividend the Company has made to our stockholders. We also completed previously announced investments in our Performance Products business, catalysts for polyurethane insulation and high value performance amines used in the semiconductor industry. As market demand recovers, we expect to realize benefits from the growth capital investments we completed in 2025 and we will continue to focus on what we can control and where we can create value.
For over 50 years, our employees have been using science and ingenuity to create innovations that play a critical role in the everyday lives of millions of people. Our Company and employees are united around a common goal: enriching lives through innovation. In 2025, we continued our pursuit of this goal by investing in our people and our culture through career development programs and a culture of continuous improvement. We also furthered the Company’s strong philanthropic ideals through contributions to causes around the world to make a difference in the communities in which we live and operate. Huntsman continues to embrace the entrepreneurial spirit of our founder, Jon M. Huntsman, and his core values of honesty, integrity, respect and responsibility.
Another cornerstone of our culture is safety. We are proud of the recognition and awards the Company has received for safety across the industry and throughout the world. We continue to invest and have seen continuous improvements in both personal and process safety performance since 2019. In 2025, we reaffirmed our commitment to Zero Harm with a campaign designed to bring awareness to our global safety culture program, reinforcing the Company’s commitment to safety, health and environmental responsibility.
Lastly, after more than 15 years of distinguished service on our Board, Dr. Mary C. Beckerle has decided to retire from our Board and will not stand for re-election at the Annual Meeting. Throughout her tenure on the Board, Dr. Beckerle has provided invaluable

guidance, strategic insight and steadfast commitment to the Company’s mission and values. The Board and management extend their deepest gratitude to Dr. Beckerle for her exceptional contributions and leadership and wish her continued success in her future endeavors.
​
A Special Note from Cynthia L. Egan, our Lead Independent Director and Non-Executive Vice Chair of the Board
​
In my capacity as Lead Independent Director and Non-Executive Vice Chair of the Board, I am honored to represent the independent members of the Board of Directors. Our Board of Directors is comprised of esteemed leaders who have earned a reputation for their business tenacity, deep wisdom and integrity. Our Board takes its responsibility to our stockholders seriously. Our independent Directors regularly engage with management to ensure effective oversight of risks and the advancement of the long-term strategic priorities—innovating, driving commercial excellence, and optimizing our portfolio for growth. With each of their backgrounds and their demonstrated skills and expertise, the members of our Board bring a unique and effective mix of industry knowledge, business and financial acumen, risk oversight and fresh perspectives to the boardroom, and I am confident in the ability of our Board to oversee management to develop and execute the Company's long-term strategic plans.
*         *         *
While 2025 continued to present challenges for the chemical industry as a whole, the Board appreciates management’s intense monitoring of external events, and their proactive and meaningful actions to advance operations and drive innovation. We are optimistic about the Company’s future and remain focused on delivering long-term value to you, our stockholders. On behalf of Huntsman’s Board of Directors and management team, thank you for your investment and continued confidence in our Company.
Sincerely,
​

Board Leadership Structure
​
The Board is responsible for creating a leadership structure that provides effective independent oversight of management. The Board believes it is important to preserve flexibility on a case-by-case basis to determine the most effective leadership structure for the Company based on an assessment of the Company’s circumstances and needs at any given time. Our Corporate Governance Guidelines provide the Board with this flexibility, including the ability to separate the positions of Chairman of the Board and Chief Executive Officer if circumstances warrant. The Board believes our Company and our stockholders benefit from this flexibility, as our directors are well positioned to evaluate and determine our leadership structure given their extensive knowledge of our leadership team, our strategic goals, the industry in which we operate and the opportunities and challenges we face.
At this point in time, the Board believes that the interests of the Company and its stockholders are best served through a leadership structure that combines the positions of Chairman of the Board and Chief Executive Officer. The Board has determined that this is 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.
Information regarding the duties and responsibilities of the Chairman of the Board and the Lead Independent Director and Non-Executive Vice Chair of the Board is provided below.

•
Providing leadership on matters where potential conflicts of interest may be perceived to exist;
​
•
Serving as a primary Board contact for stockholders to communicate with the independent directors;
​
•
Presiding at executive sessions of the independent directors without management present;
​
•
Calling special meetings of the Board upon request; and
​
•
Presiding at Board and stockholder meetings and performing such other duties as may be delegated by the Board in the Chairman’s absence.
​
 ​
​
Considerations in Selecting this Leader:
Peter R. Huntsman has served as the Chairman of the Board since 2018. Mr. Huntsman has demonstrated expertise across many facets of the global chemical industry and has served in both operational and executive leadership positions at the Company since 1983 and as the Company’s President and Chief Executive Officer since 2000. His successful execution of various strategic, operational, financial, regulatory and governance milestones, as well as his deep knowledge of the opportunities and challenges facing the Company and the chemical industry, makes him well qualified to serve as the Chairman of the Board.
​ ​
Considerations in Selecting this Leader:
Cynthia L. Egan has served as Lead Independent Director and Non-Executive Vice Chair of the Board since 2022. Ms. Egan’s service on the Board since 2020, as well as her experience chairing the Governance Committee, gives her a well-informed perspective as she provides an effective balance to the Chairman and contributes to a strong governance structure for the Board. She brings the Board deep expertise around corporate governance practices that she has developed while serving on boards of other publicly traded companies.

Board Composition And Background
​
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. Beginning in 2018, the Board undertook a multi-year director succession and refreshment process that resulted in the addition of eight new independent directors (including four women and, as a retired Vice Admiral of the U.S. Navy, one veteran) to the Board. We believe our Board, which is comprised of individuals from a variety of backgrounds, currently has the right mix of skills and experience to successfully oversee the Company; however, we regularly assess the composition of the Board and are continuously engaged in Board succession planning. The Board approved the reduction of the size of the Board from ten to nine, effective as of the Annual Meeting following the retirement of Dr. Beckerle.
Our Board is composed of highly-qualified 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 well-rounded range of attributes, perspectives and experiences of our nine director nominees.

Executive Compensation (Proposal 2)
​
​
WE ASK THAT YOU VOTE TO APPROVE OUR SAY-ON-PAY PROPOSAL
​
​
At the Annual Meeting, our stockholders will again have an opportunity to cast an advisory say-on-pay vote on the compensation paid to our named executive officers (“NEOs”). We ask you to vote “FOR” to approve our NEO compensation using the enclosed proxy card. Please see “Proposal 2—Advisory Vote to Approve Named Executive Officer Compensation.” Please also read our “Compensation Discussion and Analysis” beginning on page 32 for more information regarding our executive compensation program in 2025.
​
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 2025.
​
Company Performance Highlights
​
In 2025, our Company continued to experience weak global markets seen throughout the chemical industry. Within this environment, we delivered strong cash generation in addition to solid performance on key financial, strategic, innovation and environmental, health and safety initiatives. Points of emphasis include:
•
Return to Shareholders:   Returned approximately $146 million to stockholders through dividends and took action to reset the dividend to 35 cents per share annually to preserve financial flexibility and protect our balance sheet through the prolonged industry-wide trough
​
•
Financial:   Delivered strong cash performance, generating approximately $298 million of cash flow from operations and $125 million of free cash flow(1); delivered on cost realignment and restructuring initiatives, achieving approximately $100 million of annualized run rate savings by year-end 2025; reduced our working capital cash conversion cycle and managed capital expenditures prudently given the economic environment
​
•
Strategic:   Continued focus on portfolio and as part of our cost realignment activities progressed the closure of seven facilities in our worldwide network with the majority of closures in Europe; received the final payout of $41 million by completing the separation of our Shanghai Lianhang Isocyanate Company joint venture in China; continued to expand our global business services centers (GBS) in Southeast Asia, Latin America and Eastern Europe, with approximately 650 associates working at these sites at the end of 2025
​
•
Safety Performance:   Continued improvement since 2019 in our target metrics in personal safety and process safety; launched a global campaign to reaffirm our goal of attaining a “Zero Harm” environment, protecting our people, planet and processes from harm
​
•
Innovation:   Successful collaboration with our customers to develop next generation products in the automotive and semiconductor industries
​
•
Sustainability:   Published our 2024 sustainability report which includes limited assurance regarding our greenhouse gas emissions and water usage
​
•
Planet and People:   Continued to invest in and give back to our communities globally, including by donating to and volunteering at local charities providing essential relief and awarding university and trade school scholarships to promising high school students in underprivileged communities
​
​
2025 Realized Pay Aligns With Performance
​
The Compensation Committee, with the assistance of Meridian, its independent compensation consultant, designed a compensation structure focused on balancing long-term and short-term compensation in line with our pay-for-performance philosophy taking into account the prolonged and deep trough experienced throughout the chemical industry. The Compensation Committee believes the compensation results for 2025 demonstrate the effectiveness of the design in achieving these objectives. This is reflected in the payout levels of our annual and long-term incentive plans:
•
Cash Performance Awards:   Payout of the 2025 annual cash performance awards for our CEO and other executive officers was 70.6% of target due in large part to better than targeted free cash flow, which accounted for 40% of the cash performance incentive plan, and achieving other strategic and operational metrics which accounted for 20% of the cash performance incentive plan, with zero payout for adjusted EBITDA(2), which was below target.
​
•
Performance Share Unit Awards:   No payout was earned for the 2023-2025 performance share unit awards, reflecting our TSR under performance relative to peers.(3)

•
CEO Realizable Pay:   A strong correlation exists between the realizable value of our CEO’s compensation awarded in the last three years and our cumulative total shareholder return. In 2025, our CEO’s realized compensation was $5 million compared to target compensation of $13.1 million.
​
​
(1)
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. See Appendix A for additional information regarding free cash flow and a reconciliation to operating cash from continuing operations.
​
(2)
Throughout this Proxy Statement, we refer to our adjusted EBITDA, which is a non-GAAP financial measure. See Appendix A for additional information regarding adjusted EBITDA and a reconciliation to net income.
​

For additional discussion of our three-year cumulative TSR achievement and our 2023 Performance Peers, see “Compensation Discussion and Analysis-2025 Executive Compensation Decisions-Long-Term Equity Compensation-Payout of 2023 Performance Share Unit Awards.”
​
​
Vast Majority Of 2025 NEO Pay Remains At Risk(1)
​
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 2025, approximately 90% of the CEO’s total target direct compensation was at risk and tied to annual performance against established goals and/or the performance of our stock. Comparably, approximately 72% of total target direct compensation in 2025 of our other NEOs on average was at risk.(2)
[MISSING IMAGE: pc_trgt-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 2025, and (iii) the aggregate grant date fair value of long-term equity incentive awards granted in 2025. The amounts realized by our NEOs with respect to the annual cash performance awards and long-term equity incentive awards granted in 2025 depend, as applicable, on the level of attainment of the relevant performance goals and the value of our common stock when the awards vest.
​
(2)
We consider compensation to be “at risk” if it is subject to performance-based payment vesting conditions or if its value depends on actual stock price performance or returns relative to peers.
​
(3)
Mr. Anthony P. Hankins did not receive an equity award in 2025 and his compensation has thus been excluded. Mr. Hankins retired from the Company effective December 31, 2025.
​
​
Independent Registered Public Accounting Firm (Proposal 3)
​
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, 2026 using the enclosed proxy card.
​
Stockholder Proposal Requesting An Independent Board Chair Policy (Proposal 4)
​
We ask you to vote “AGAINST” the stockholder proposal requesting an independent board chair policy using the enclosed proxy card. Please see page 74 for our Board’s Statement in Opposition.

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 2025 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 2025, Mr. Sewell participated 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. Each of Dr. Beckerle, Ms. Dulá, Ms. Egan, Mr. Espeland and Retired Vice Admiral Tighe participated in this program.
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 for 2025 are below.

CORPORATE GOVERNANCE HIGHLIGHTS
​
Board Composition And Background
​
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. Beginning in 2018, the Board undertook a multi-year director succession and refreshment process that resulted in the addition of eight new independent directors (including four women and, as a retired Vice Admiral of the U.S. Navy, one veteran) to the Board. The size of the Board will be reduced from ten members to nine members effective as of the Annual Meeting. We believe our Board, which is comprised of individuals from a variety of backgrounds, currently has the right mix of skills and experience to successfully oversee the Company; however, we regularly assess the composition of the Board and are continuously engaged in Board succession planning.
Our Board in composed of highly-qualified 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 well-rounded range of attributes, perspectives and experiences of our nine director nominees.

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 2025, the Board met four times, and the non-management directors met in executive session four times. During 2025, each director other than Mr. Muñoz 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.
​
Due to unavoidable pre-existing business scheduling conflicts, Mr. Muñoz attended 69% of such meetings.
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 the 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 the Company for the Board to make a determination each time it elects 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.
Our Bylaws also provide the Board with the flexibility 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 currently serving as Non-Executive 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 potential conflicts of interest may be perceived to exist. 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 Lead Independent Director and Non-Executive Vice Chair of the Board, 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 Lead Independent Director and Non-Executive Vice Chair of the Board 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 be comprised of 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 a 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 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 our Company (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 our Company 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 Company’s 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 Company’s 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, our Company 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 our Company has 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.
​
For purposes of the foregoing description of the Director Independence Criteria only, references to “our Company” mean Huntsman Corporation and its subsidiaries, collectively. With the assistance of counsel, the Nominating and Corporate Governance Committee (“Governance Committee”) annually reviews 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 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 considers all relevant facts and circumstances, including any persons or organizations which the director has an affiliation, including related party relationships as described in the Company’s Related Party Transactions Policy discussed under “Additional Information-Certain Relationships and Related Transactions” other than the compensation arrangements, which are reviewed by the Compensation Committee.
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 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 more than 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 Chairman, President and CEO, is not an independent director because he is employed by our Company.

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 our Company (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 our Company (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 our Company receives any consulting, advisory or other compensatory fee from us; or
​
•
The member is otherwise an affiliated person of our Company.
​
For purposes of the foregoing description of the Audit Committee independence criteria only, references to “our Company” mean Huntsman Corporation and its subsidiaries, collectively. 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, as each is defined by the NYSE rules, Exchange Act and the rules and regulations of the SEC. 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 U.S. public company audit committees.

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 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 officers. However, the CEO is not present while decisions regarding his compensation are made. In addition, each Compensation Committee meeting typically includes an executive session without members of management present. The Compensation Committee regularly reports to the full Board regarding executive compensation matters.

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 in this regard, and the Audit 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 that 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 the Board’s 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 recognize the importance of developing, implementing and maintaining cybersecurity measures to safeguard our information systems, shield our operational technologies in our manufacturing plants and protect the confidentiality, integrity and availability of our data.

Our Board has delegated the focused oversight of cybersecurity risks to the Audit Committee. Our Audit Committee is composed of board members with diverse expertise, including cyber operations, risk management, technology and finance, equipping the Audit Committee to oversee cybersecurity risks effectively. In particular, our Audit Committee receives quarterly updates from our Chief Information Officer on cybersecurity risk reviews, including current cybersecurity landscape and emerging threats; status of ongoing cybersecurity initiatives and strategies; incident reports and learnings from any cybersecurity events; and compliance with regulatory requirements and industry standards.
The Audit Committee regularly reports to our Board on these matters. Additional information relating to our cybersecurity risk management, strategy and governance is contained in the section titled “Cybersecurity” in the Company’s 2025 Form 10-K.
CORPORATE RESPONSIBILITY
At Huntsman, corporate responsibility is an integral 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 comprised of senior representatives from all our divisions and key functions. Our CSO reports progress to the Sustainability Committee of the Board, and the Board regularly discusses various EHS matters.
Since 2010, we have published our annual Huntsman sustainability report to document our progress and demonstrate our commitment. The report is prepared in accordance with both the GRI standards and the Sustainability Accounting Standards Board (SASB) standards. Additionally, our disclosure aligns with the Task Force on Climate-related Financial Disclosures. We also participate in the Carbon Disclosure Project for climate and water disclosures. For more information on our commitment to corporate responsibility, please visit www.huntsman.com/Sustainability. Please note, however, that information contained on the website is not incorporated by reference in this Proxy Statement or considered to be a part of this document.
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 of our directors attended the 2025 annual meeting.
DIRECTOR QUALIFICATION STANDARDS AND DIVERSITY
The minimum qualifications and specific qualities and skills required for directors are set forth in our 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 director 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. The Governance Committee regularly engages third party search consultants to identify potential 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 2027 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.

​
Company Performance Highlights
​
In 2025, our Company continued to experience weak global markets seen throughout the chemical industry. Within this environment, we delivered strong cash generation in addition to solid performance on key financial, strategic, innovation and environmental, health and safety initiatives. Points of emphasis include:
•
Return to Shareholders:   Returned approximately $146 million to stockholders through dividends and took action to reset the dividend to 35 cents per share annually to preserve financial flexibility and protect our balance sheet through the prolonged industry-wide trough
​
•
Financial:   Delivered strong cash performance, generating approximately $298 million of cash flow from operations and $125 million of free cash flow(1); delivered on cost realignment and restructuring initiatives, achieving approximately $100 million of annualized run rate savings by year-end 2025; reduced our working capital cash conversion cycle and managed capital expenditures prudently given the economic environment
​
•
Strategic:   Continued focus on portfolio and as part of our cost realignment activities progressed the closure of seven facilities in our worldwide network with the majority of closures in Europe; received the final payout of $41 million by completing the separation of our Shanghai Lianhang Isocyanate Company joint venture in China; continued to expand our global business services centers (GBS) in Southeast Asia, Latin America and Eastern Europe, with approximately 650 associates working at these sites at the end of 2025
​
•
Safety Performance:   Continued improvement since 2019 in our target metrics in personal safety and process safety; launched a global campaign to reaffirm our goal of attaining a “Zero Harm” environment, protecting our people, planet and processes from harm

2025 Compensation Design Objectives
​
Key design elements of the pay structure approved by the Compensation Committee for 2025 included:
•
Align Pay with Performance
​
•
Align NEO Interests with Stockholder Interests
​
•
Support a Competitive Compensation Structure
​
•
Encourage Long-Term Focus
​
•
Discourage Excessive Risk Taking
​
​
Compensation Structure And Design
​
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. Key features of the program include:
•
Alignment of Pay to Share Price Performance:   Annual and long-term incentive plans designed to link executives’ pay with Company strategies and share price performance
​
•
Benchmarking:   Robust compensation benchmarking against a peer group of companies we compete against for talent
​
•
Significant Portion of Pay at Risk:   A significant portion of our NEO’s total compensation is “at risk” by being tied to specific and measurable performance objectives and the performance of our stock price
​
•
Governance Practices:   Comprehensive policies and practices intended to create a sound compensation governance process and support well-informed decision-making
​
​
2025 Realized Pay Aligns With Performance
​
The Compensation Committee, with the assistance of Meridian, its independent compensation consultant, designed a compensation structure focused on balancing long-term and short-term compensation in line with our pay-for-performance philosophy taking into account the prolonged and deep trough experienced throughout the chemical industry. The Compensation Committee believes the compensation results for 2025 demonstrate the effectiveness of the design in achieving these objectives. This is reflected in the payout levels of our annual and long-term incentive plans:
•
Cash Performance Awards:   Payout of the 2025 annual cash performance awards for our CEO and other executive officers was 70.6% of target due in large part to better than targeted free cash flow, which accounted for 40% of the cash performance incentive plan, and achieving other strategic and operational metrics which accounted for 20% of the cash performance incentive plan, with zero payout for adjusted EBITDA(2), which was below target.
​
•
Performance Share Unit Awards:   No payout was earned for the 2023-2025 performance share unit awards, reflecting our TSR under performance relative to peers.(3)
​
•
CEO Realizable Pay:   A strong correlation exists between the realizable value of our CEO’s compensation awarded in the last three years and our cumulative total shareholder return. In 2025, our CEO’s realized compensation was $5 million compared to target compensation of $13.1 million.
​

Free cash flow 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. See Appendix A for additional information regarding free cash flow and a reconciliation to operating cash from continuing operations.

​
Our Response To Stockholder Feedback
​
We continuously engage with our stockholders and are always available to discuss topics relevant to our compensation practices. As a result, we have made numerous changes to our practices over the years. In doing so, the Compensation Committee has consistently implemented improvements that further align incentive-based payouts with the creation of stockholder value.
At our 2025 annual meeting, the say-on-pay proposal received the support of approximately 96% of the stockholders casting their votes. Approximately 85% and 97% of the shares voted at our 2024 and 2023 annual meetings, respectively, were voted in favor of the advisory say-on-pay proposal. Looking forward and back, the Compensation Committee carefully considers the say-on-pay results and the stockholder feedback we received in determining executive compensation.
COMPENSATION PROGRAM HIGHLIGHTS
​
Vast Majority Of 2025 NEO Pay Remains At Risk(1)
​
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 2025, approximately 90% of the CEO’s total target direct compensation was at risk and tied to annual performance against established goals and/or the performance of our stock. Comparably, approximately 72% of total target direct compensation in 2025 of our other NEOs on average was at risk.(2)
[MISSING IMAGE: pc_trgt-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 2025, and (iii) the aggregate grant date fair value of long-term equity incentive awards granted in 2025. The amounts realized by our NEOs with respect to the annual cash performance awards and long-term equity incentive awards granted in 2025 depend, as applicable, on the level of attainment of the relevant performance goals and the value of our common stock when the awards vest.
​
(2)
We consider compensation to be “at risk” if it is subject to performance-based payment vesting conditions or if its value depends on actual stock price performance or returns relative to peers.
​
(3)
Mr. Anthony P. Hankins did not receive an equity award in 2025 and his compensation has thus been excluded. Mr. Hankins retired from the Company effective December 31, 2025.

REALIZABLE PAY ANALYSIS
​
Analyses of realizable pay provides the Compensation Committee with a tool to validate the alignment of our NEOs’ compensation with the creation of stockholder value. Realizable pay reflects the earned value of annual cash performance awards and the tangible incentive value of equity awards based on changes 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. This analysis is intended as a supplement to the “Pay versus Performance” section beginning on page 64 of this Proxy Statement.
The chart below demonstrates strong alignment of our CEO’s realizable compensation with Company performance for each of 2023, 2024, and 2025.
[MISSING IMAGE: bc_tsrtrgt-pn.jpg]
“Target Compensation” for each year is defined as the sum of the target compensation opportunity including: (1) base salary, (2) annual cash performance award at target, and (3) the grant date value of equity incentive awards, as approved annually by the Compensation Committee.
“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 and restricted stock) calculated using our stock price, in all cases, as of December 31, 2025.
“Cumulative TSR” above is measured using the closing stock price at the beginning and end of the performance period and slightly differs from the cumulative TSR value we use to determine PSU 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 2025
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 the Company’s 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 target 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 increases.

HUNTSMAN CORPORATION: PROXY STATEMENT
​
​
The total target direct compensation levels for our NEOs in 2025 were comprised of the following elements.
​
Compensation Element
​ ​ ​ ​ ​ ​ ​
Description and Purpose of the Element
​
​
Annual Cash
Compensation
​ ​ ​
Base Salary
​ ​ ​
Reflective of the NEO’s responsibilities, tenure, job performance, special circumstances (such as international assignments) and the market for the NEO’s services.
​
​
Annual Cash Performance Award
​ ​ ​
Cash performance awards are earned based on Company performance measured over our fiscal year against preset goals and strategic initiatives. For 2025, 100% of our annual cash performance awards were linked to the achievement of preset free cash flow targets, pre-determined strategic and operational metrics, and adjusted EBITDA.
​
​
Long-Term Equity-Based Compensation
​ ​ ​
Performance Share Units
​ ​ ​
Performance share unit awards are earned based on Company performance measured over three fiscal years against preset goals related to relative TSR.
For 2025, performance share unit awards represented 60% of equity-based compensation for each of our NEOs.
​
​
Restricted Stock
​ ​ ​
Restricted stock awards are ratably earned over a three-year service period, with the realizable value tied to the value of our common stock at the time of vesting. Three-year ratable vesting provides both retention value as well as a long-term focus.
For 2025, restricted stock awards represented 40% of equity-based compensation for each of our NEOs.
​
A detailed discussion of 2025 total target direct compensation of our NEOs and graphical illustrations of the proportionate amount of performance-based compensation, is set forth below in “2025 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.(1)
​
​
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.(2)
​
​
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”). Mr. Huntsman has a separate severance arrangement.
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.(3)

2025 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.
​
2025 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. Huntsman, Lister, Rogers and Wright would receive a modest increase to their base salary rate consistent with the average merit salary adjustments provided to our employee population generally.

​
​
2025 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.
2025 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 2025 award pool were based on the achievement of financial and strategic performance objectives discussed below.
2025 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.

​
The following table provides additional detail regarding the performance measures selected for the 2025 annual cash performance awards.
​
Performance Measure
​ ​ ​
What It Is
​ ​ ​
Why We Believe It Is Important
​
​
Adjusted EBITDA
​ ​ ​
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
​ ​ ​
Measure 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
​ ​ ​
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
​
​
Strategic and Operational Initiatives
​ ​ ​
An array of quantitative and qualitative metrics on which the Compensation Committee and the Board can evaluate the performance of management and determine an appropriate reward
​ ​ ​
Near-term measures focusing management on specific value creation initiatives such as cost management, cash generation and working capital management, execution of organic growth investments, innovation on product offerings, and other strategic initiatives. Also, measures achievement of environmental performance and injury reduction objectives
​
The Compensation Committee established threshold, target, and maximum performance goals for each of the following performance measures relevant to our NEOs (dollars in millions):
​
Performance Measure
​ ​
Threshold
​ ​
Target
​ ​
Maximum
​
​ Adjusted EBITDA ​ ​ ​ $ 400 ​ ​ ​ ​ $ 482 ​ ​ ​ ​ $ 578 ​ ​
​
​ Free cash flow ​ ​ ​ $ 60 ​ ​ ​ ​ $ 115 ​ ​ ​ ​ $ 170 ​ ​
​
​ Strategic and Operational Initiatives ​ ​ ​ ​ 0% ​ ​ ​ ​ ​ 100% ​ ​ ​ ​ ​ 250% ​ ​
Targets are set at levels that require significant effort to achieve given the anticipated economic and industry environment. For 2025, the target levels for each of Adjusted EBITDA and Free Cash Flow were set above the corresponding 2024 performance. For each performance measure, achievement below the threshold goal results in no payout, payout for achievement at the target goal results in a payout of 100% of target, and achievement of the maximum goal results in a payout of 250% of target. Payouts for achievement between goal levels are calculated using linear interpolation. The annual cash performance award program is subject to Compensation Committee and board oversight and discretion to adjust awards on an individual or collective basis.
2025 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 bonus percentage and the potential payout range for each NEO.
​
Executive Officer
​ ​
Target %
of Base Salary
​ ​
Payout Range of Target
​
​ Peter R. Huntsman ​ ​ ​ ​ 140% ​ ​ ​ ​ ​ 0% – 250% ​ ​
​
​ Philip M. Lister ​ ​ ​ ​ 80% ​ ​ ​ ​ ​ 0% – 250% ​ ​
​
​ Anthony P. Hankins ​ ​ ​ ​ 80% ​ ​ ​ ​ ​ 0% – 250% ​ ​
​
​ R. Wade Rogers ​ ​ ​ ​ 70% ​ ​ ​ ​ ​ 0% – 250% ​ ​
​
​ Scott J. Wright ​ ​ ​ ​ 70% ​ ​ ​ ​ ​ 0% – 250% ​ ​
​
​
The individual bonus targets and payout ranges 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. Actual payouts of individual annual cash performance awards depend upon both Company performance and individual contributions to our success.

Performance in strategic and operational initiatives included, among others, the following:
•
Completed key organic growth projects and innovation programs;
​
•
Delivered approximately $100 million of annualized run rate savings from the near completion of our cost realignment program;
​
•
Improved cash conversion cycle by 10%, through our cash management program;
​
•
Successfully renegotiated and increased our US securitization facility and maintained net debt at similar levels at the end of 2025 compared to the end of 2024, despite the deterioration in the chemical industry operating environment; and
​
•
EH&S performance was measured against preset goals and was substantially in line with target performance.
​
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 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 cash performance award was calculated according to the achievement for each separate performance measure.
Each NEO’s 2025 annual cash performance award was determined in accordance with the following formula:

LONG-TERM EQUITY COMPENSATION
​
For 2025, the Compensation Committee approved the grant of 1) performance share units that would vest based on Huntsman’s relative TSR performance; and 2) time-based restricted stock.
Equity Award Mix.   For 2025, the Compensation Committee approved an award mix of 60% of total target award value delivered in performance share units and 40% of total target award value delivered in restricted stock. The Committee believes the emphasis on three-year relative TSR performance aligns our NEOs’ interests with our stockholders.
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 2025 long-term equity incentive awards approved for the NEOs were as follows:

Mr. Hankins did not receive a long-term equity incentive award in 2025. Mr. Hankins retired from the Company effective December 31, 2025.
​
Performance-Based Awards Granted in 2025.   The relative TSR performance share units granted in 2025 will vest or lapse on December 31, 2027, depending on the achievement of relative TSR performance during the performance period from January 1, 2025 to December 31, 2027, 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 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 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.
The Company peer group used to determine relative TSR performance (the “2025 Performance Peers”) represents industry-specific public companies. Although there is some overlap between the two groups, the 2025 Performance Peers, as further described below, differ from our Proxy Peers in that our 2025 Performance Peers are companies whose valuations are influenced by similar financial and economic factors and we compete against these companies for market share and investor capital.
The 2025 Performance Peers, which we developed with guidance from Meridian, were as follows:
​
•
Ashland Global Holdings Inc.
​
 ​ ​ ​
•
Dow Inc.
​
 ​ ​ ​
•
Lanxess AG
​
 ​
​
•
BASF Corp.
​
 ​ ​ ​
•
Eastman Chemical Company
​
 ​ ​ ​
•
Olin Corporation
​
 ​
​
•
Celanese Corporation
​
 ​ ​ ​
•
Evonik Industries AG
​
 ​ ​ ​
•
The Chemours Company
​
 ​
​
•
Clariant AG
​
 ​ ​ ​
•
H.B. Fuller Company
​
 ​ ​ ​
•
Westlake Chemical
​
 ​
The 2025 Performance Peers reflect certain changes from the 2024 Performance Peers. Specifically, Covestro AG (due to its pending acquisition) and Trinseo S.A. (due to its distressed financial position) were removed and replaced with The Chemours Company and Olin Corporation.
For each 2025 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 2025 Performance Peers at the end of the performance period. The maximum number of performance share units that may be earned is 250% of the target number of shares granted if our TSR performance ranks in the 90th percentile of the 2025 Performance Peers. If our TSR performance ranks below the 25th percentile of the 2025 Performance Peers, then no performance share units vest. Median performance at 50th percentile results in payout at target.
Earned 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.

Based on the award parameters, the Company’s TSR of -53.1% for the three-year period ended December 31, 2025 ranked at the 18th percentile among the 2023 Performance Peers, resulting in no final payout of the number of performance share units originally awarded.

HOW WE DETERMINE EXECUTIVE COMPENSATION
As directed by the Compensation Committee, our CEO and our Senior Vice President and head of Global Human Resources coordinates the annual review of the executive compensation program. This review includes an evaluation of our performance, corporate goals and objectives relevant to compensation, and compensation payable under various circumstances, including upon retirement or a change of control. In making its decisions regarding each NEO’s compensation, the Compensation Committee considers the nature and scope of all elements of an executive’s total compensation package, the executive’s responsibilities and his or her effectiveness in supporting our key strategic, operational and financial goals. This review includes an evaluation of each NEO’s historical pay and career development, individual and corporate performance, and competitive practices and trends.
​
Roles Of The Compensation Committee, Executive Management And The Compensation Consultant
​
The Compensation Committee, the Committee’s independent compensation consultant, Meridian, and executive management each play a key role in the Compensation Committee’s annual review, evaluation and approval of our executive compensation programs.

​
CONSIDERATION Of PEER COMPENSATION
​
To assist in its determination of the 2025 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 overall assessment of the competitiveness of our executive compensation program. Criteria used to select the Proxy Peers include financial measures (i.e., revenue, market capitalization, enterprise value and assets) and the industry segment in which we operate.

​
For the compensation benchmarking review that informed the 2025 compensation decisions, the Compensation Committee determined that certain changes were required to the Proxy Peer group to better position our Company in terms of key measures of size. Specifically, LyondellBasell Industries, Sherwin-Williams and Ecolab were removed due to revenue and market capitalization being significantly greater than ours. Further, Cabot Corporation and H.B. Fuller Company were added, as they are better aligned with our revenue and market capitalization. Following these changes, the 2025 Proxy Peers consisted of the following 19 companies:
​
•
Air Products & Chemicals Inc.
​
 ​ ​ ​
•
Eastman Chemical Company
​
 ​ ​ ​
•
RPM International Inc.
​
 ​
​
•
Avery Dennison Corporation

​
 ​ ​ ​ ​ ​ ​ ​ ​ ​
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 ADVISER
​
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 and related governance matters. 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 2025 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 sold or shares netted 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, 2025, 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, 2025:

​
​
CLAWBACK POLICY
​
In 2023, we adopted the amended and restated Huntsman Corporation Clawback Policy, effective as of October 26, 2023 (the “Clawback Policy”), for compliance with the NYSE listing standards and Section 10D of the Exchange Act. The Clawback Policy applies to current or former Section 16 officers and only in the event that the Company is required to prepare an accounting restatement due to the material noncompliance of the Company with any financial reporting requirement under the securities laws; misconduct on the part of the executive is not required. Under the Clawback Policy, we are required to recover incentive-based compensation (as that term is defined in Section 10D of the Exchange Act) erroneously received within the three fiscal years preceding the date a restatement is determined to be required, subject to certain limited exceptions.
​
OPTION AWARDS
​
In response to Item 402(x)(1) of Regulation S-K, the Company does not currently grant new awards of stock options, stock appreciation rights, or similar option-like instruments. Accordingly, the Company has no specific policy or practice on the timing of awards of such options in relation to the disclosure of material nonpublic information by the Company. In the event the Company determines to grant new awards of such options, the Board will evaluate the appropriate steps to take in relation to the foregoing.
​
INSIDER TRADING POLICY; POLICIES On HEDGING And PLEDGING
​
We have adopted an Insider Trading Policy governing the purchase, sale, and other dispositions of our securities by directors, officers, and employees that is reasonably designed to promote compliance with insider trading laws, rules and regulations, and the standards of the NYSE. It also is our Company’s policy to abide by applicable federal securities regulations and NYSE listing standards when engaging in any corporate repurchase or sale of Company securities.
Our Insider Trading Policy prohibits all transactions designed to hedge or offset decreases in the market value of our equity securities and engaging in short-term speculative transactions in our securities. The policy also prohibits 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. A copy of the Insider Trading Policy was included as an exhibit in our 2025 Form 10-K.

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:
•
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 EHS 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 the Clawback Policy, which 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.

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 based on a Monte Carlo valuation and 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 performance share units at the grant date assuming that the highest level of performance conditions will be achieved is $16,408,508, $2,906,348, $1,660,792 and $1,494,694 for Messrs. Huntsman, Lister, Rogers, and Wright, 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, 2025, 2024, or 2023, 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 annual cash performance awards that were earned for the years included. Amounts earned for a given year are paid during the first quarter of the following year. These awards are discussed in further detail under “Compensation Discussion and Analysis-2025 Executive Compensation Decisions-2025 Annual Cash Performance Award.”
​
(3)
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 2025” for additional information regarding the 2025 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 2025. See “—Nonqualified Deferred Compensation in 2025” for additional information.

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.

As a citizen of the U.K. with residence in the U.S., we incurred foreign assignment costs on Mr. Hankins’ behalf during 2025 that included $194,563 in housing allowances and costs and $93,109 for perquisites, including foreign assignment and car allowances. In addition, we incurred $300,185 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 2025, we incurred $1,817 to gross-up Medicare taxes associated with our contributions to the Supplemental Savings Plan.

(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. Lister 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 2025 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.
​
(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.

These columns show annual cash performance awards granted under our annual cash performance award program to the NEOs in 2025. See the chart and accompanying narrative disclosure in “Compensation Discussion and Analysis—2025 Executive Compensation Decisions—2025 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 2025 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 2025 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 2025 that vest on December 31, 2027, subject to the achievement of relative TSR performance metrics. Amounts reported in the (i) “Threshold” column reflect the threshold number of performance share units (25% of target) that may be earned for a minimum level of performance, (ii) “Target” column reflects the target number of performance share units, or 100%, that may be earned and (iii) “Maximum” column reflect the maximum number of performance share units that may be earned (250% of target), in each case, based on relative TSR achievement against applicable performance metrics. If performance is below the threshold, no performance share units are earned. See “Compensation Discussion and Analysis—2025 Executive Compensation Decisions—Long-Term Equity Compensation” for additional information with respect to these awards.
​
See “Compensation Discussion and Analysis—2025 Executive Compensation Decisions—Long-Term Equity Compensation” for additional information with respect to these awards.

This column shows the number of restricted shares granted under the 2016 Stock Incentive Plan to the NEOs in 2025. 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.
​
(4)
This column shows the full grant date fair value of the awards computed in accordance with FASB ASC Topic 718. With respect to the performance share units, 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 forfeitures.

NARRATIVE DISCLOSURE TO SUMMARY COMPENSATION TABLE AND GRANTS OF PLAN-BASED AWARDS TABLE
Information regarding the elements of our executive compensation program for 2025 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 “2025 Summary Compensation Table” and “Grants of Plan-Based Awards in 2025” 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 based on 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 2025, 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 letter agreement with Mr. Hankins terminated upon his retirement from the Company effective December 31, 2025. The primary purpose of this letter agreement was to provide Mr. Hankins with details regarding repatriation to his home country following the completion of his foreign assignment. This letter agreement also defined the initial elements of Mr. Hankins’ compensation package, including base salary and an annual cash performance award, and provided 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.

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 19. Employee Benefit Plans” to our consolidated financial statements included in our 2025 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 19. Employee Benefit Plans” to our consolidated financial statements included in our 2024 Form 10-K. For purposes of performing these calculations, a normal retirement (earliest unreduced) age of 65 was utilized for Messrs. Huntsman, Lister, and Rogers. Mr. Hankins has passed his normal retirement age of 62 so his accrued benefit is payable immediately. 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, 2025.
​

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, 2025, Mr. Hankins had served 45.4 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.
​
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, Rogers and Wright were participants in the Huntsman Pension Plan in 2025. 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, Rogers and Wright were participants in the Supplemental Executive Retirement Plan in 2025. 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” under the Huntsman Pension Plan is subject to the compensation limit applicable to tax-qualified plans of $350,000 for 2025. 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 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 2025 pay credits for the Huntsman Pension Plan are $42,000 for Mr. Huntsman, $42,000 for

​
Mr. Lister, $42,000 for Mr. Rogers, and $42,000 for Mr. Wright. The 2025 pay credits for the Supplemental Executive Retirement Plan are $118,095, $34,781, $26,256, and $30,522 for Messrs. Huntsman, Lister, Rogers, and Wright, 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 2025 interest credits for the Huntsman Pension Plan are $182,667, $29,823, $80,168, and $10,585 for Messrs. Huntsman, Lister, Rogers, and Wright, respectively. The 2025 interest credits for the Supplemental Executive Retirement Plan are $943,509, $17,302, $43,759, and $18,339 for Messrs. Huntsman, Lister, Rogers, and Wright, 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. 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. 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%. For cash balance early retirement annuities, the plan offers subsidized benefits reduced 5% per year from the age 65 immediate, actuarially equivalent annuity plus a social security supplement temporary annuity of $25 times years of service (maximum of 30 years) payable until age 65. As of December 31, 2025, Messrs. Huntsman and Rogers are our only NEOs eligible for early retirement.
The Supplemental Executive Retirement Plan mirrors the benefits payable from the Huntsman Pension Plan. 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 the participant’s duties.
We also sponsor retirement benefit plans in connection with our operations in the U.K. Mr. Hankins participated in the Huntsman Pension Scheme for U.K. associates in the Polyurethanes division. The Huntsman Pension Scheme (U.K.) in which Mr. Hankins participated provides a target 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, 2025, Mr. Hankins passed age 62 and is fully vested in these benefits. Mr. Hankins retired from the Company effective December 31, 2025.
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 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, 2025, Mr. Lister’s additional payment was calculated at $2,331 per year.
NONQUALIFIED DEFERRED COMPENSATION IN 2025
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 75% 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 ($350,000 in 2025). As required by Section 409A, deferrals must be elected in the calendar year preceding the year in which the compensation deferred is earned. Messrs. Huntsman and Rogers did not defer any earnings into the Supplemental Savings Plan in 2025.
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 2025 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 2025.

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.
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 2025,” except that a “Disability” must also constitute a disability for purposes of Section 409A. Each of Messrs. Huntsman, Lister, Hankins and Rogers 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. Consequently, none of the earnings reported in the “Nonqualified Deferred Compensation in 2025” table above are included in the Summary Compensation Table for 2025. Participants may change their investment options at any time by contacting the plan record keeper.

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 and restated);
​
•
the Huntsman Corporation 2025 Stock Incentive Plan (the “2025 Stock Incentive Plan”) and the 2016 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 2025 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 or if the participant signs and later revokes such waiver and release of claims, 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.

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 14, 2025, we and Mr. Huntsman entered into a Third Amended and Restated Severance Agreement (the “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 and his dependents 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 CEO Severance Agreement does 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 salary, 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 of such reduction or change.
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 2025” 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 2025” above. As described under “—Pension Benefits in 2025” above, pursuant to the Huntsman Pension Scheme (U.K.), Mr. Hankins is entitled to receive annual benefits of 2∕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.”

We contract with a third-party provider for 12 months of outplacement services. To the extent these services might be utilized, we expect our cost would be as set forth herein.
​
(3)
Any acceleration of vesting of long-term equity incentive awards held by Mr. Huntsman requires the approval of the Compensation Committee, which we assume for purposes of this table would have occurred on December 31, 2025. An acceleration of Mr. Huntsman’s 385,545 unvested shares of restricted stock would have an estimated value of $3,855,450 and 596,840 target unvested performance share units would have an estimated value of $5,968,400.
​
(4)
Any acceleration of vesting of long-term equity incentive awards held by Mr. Lister requires the approval of the Compensation Committee, which we assume for purposes of this table would have occurred on December 31, 2025. An acceleration of Mr. Lister’s 67,210 unvested shares of restricted stock would have an estimated value of $672,100 and 105,715 target unvested performance share units would have an estimated value of $1,057,150.
​
(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, 2025. An acceleration of Mr. Hankins’ 30,932 unvested shares of restricted stock would have an estimated value of $309,320 and 50,146 target unvested performance share units would have an estimated value of $501,460.
​
(6)
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, 2025. An acceleration of Mr. Rogers’ 39,842 unvested shares of restricted stock would have an estimated value of $398,420 and 61,738 target unvested performance share units would have an estimated value of $617,380.
​
(7)
Any acceleration of vesting of long-term equity incentive awards held by Mr. Wright requires the approval of the Compensation Committee, which we assume for purposes of this table would have occurred on December 31, 2025. An acceleration of Mr. Wrights’ 34,689 unvested shares of restricted stock would have an estimated value of $346,890 and 54,368 target unvested performance share units would have an estimated value of $543,680.
​
(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.”

​
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
Ms. Sonia Dulá and Messrs. Curtis E. Espeland, José Muñoz and David B. Sewell each served on the Compensation Committee during 2025. None of the members of the Compensation Committee was an officer or employee of our Company during 2025 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 2025, our last completed fiscal year:
•
The median of the annual total compensation of all employees of our Company (other than Mr. Huntsman) was $87,200; and
​
•
The annual total compensation of Mr. Huntsman, as reported in the 2025 Summary Compensation Table included in this Proxy Statement, was $14,666,623.
​
•
Based on this information, for 2025 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 168 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. Since our median employee identified in 2023 departed the Company in 2025, we selected the next closest employee based on our 2023 employee population.
To identify the median employee in 2025, we took the following steps:
•
We selected December 31, 2023, the last day of our 2023 payroll year, as the determination date for purposes of identifying the median employee.

Our total global workforce, as of December 31, 2023, consisted of approximately 6,382 individuals working at our Company and consolidated subsidiaries.

As permitted by SEC rules, we excluded approximately 319 non-U.S. employees (representing less than 5% of our total global workforce as of December 31, 2023) from the employee pool used to determine our median employee.

Our employee population, after accounting for the 5% “de minimis exemption” adjustment as described above, consisted of approximately 6,063 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 2025. 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 2025 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, resulting in annual total compensation of $87,200.

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 2025 Performance Peer’s TSR.
[MISSING IMAGE: bc_capvstsr-pn.jpg]
CAP versus Net Income.   As shown in the chart below, the Company’s net income decreased in 2025 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. Beginning in 2023, the Company again used adjusted EBITDA, thus increasing the correlation.

AUDIT COMMITTEE PRE-APPROVAL POLICIES AND PROCEDURES
The Audit Committee has, by resolution, adopted policies and procedures regarding pre-approval of the performance by Deloitte & Touche LLP and affiliates of certain audit and non-audit services. Deloitte & Touche LLP and affiliates may not perform any service enumerated in Section 201(a) of the Sarbanes-Oxley Act of 2002, except as may otherwise be provided by law or regulation. Deloitte & Touche LLP and affiliates may not perform any service unless the approval of the Audit Committee is obtained prior to the performance of the services, except as may otherwise be provided by law or regulation. The Audit Committee has pre-approved the performance by Deloitte & Touche LLP and affiliates of certain audit and accounting services, certain tax services, and, provided that fees do not exceed $250,000 per individual project, certain other tax services and audit-related services. The Audit Committee has delegated to the committee chair the power to pre-approve services beyond those previously described, provided that no services may be approved that are prohibited pursuant to Section 201(a) of the Sarbanes Oxley Act of 2002 or that appear reasonably likely to compromise the independence of Deloitte & Touche LLP.

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, 2026. 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, 2025 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, 2025 be included in Huntsman’s Annual Report on Form 10-K for the year ended December 31, 2025.

PROPOSALS TO BE VOTED ON AT THE MEETING
​
​
​
PROPOSAL 1—ELECTION OF DIRECTORS

The Governance Committee has recommended, and the Board has nominated, Peter R. Huntsman, Sonia Dulá, Curtis E. Espeland, Cynthia L. Egan, Daniele Ferrari, Jeanne McGovern, José Muñoz, David B. Sewell and Retired Vice Admiral Jan E. Tighe for election. For additional information regarding the Board’s director nominees, please see the “Board of Directors—Director Nominees” section of this Proxy Statement. Each elected director will serve until our 2027 Annual Meeting, until a successor is elected and qualified, or until his or her earlier death, resignation or retirement.
You may not cumulate your votes in the election of directors. 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. Abstentions, withhold votes and any broker non-votes will not affect the outcome of the vote on the election of a director.
Unless otherwise indicated on the proxy, the persons named as proxies in the enclosed proxy will vote FOR each of the director nominees listed above. If for some reason any of the Board’s director nominees are unable to serve, or for good cause will not serve if elected, the persons named as proxies may vote for a substitute nominee recommended by the Board and, unless you indicate otherwise on the proxy card, your shares will be voted in favor of the Board’s remaining nominees. In the alternative, the Board may instead reduce the number of directors comprising the Board, as permitted by the Bylaws. If any substitute nominees are designated prior to the Meeting, we will file an amended proxy statement that, as applicable, identifies the substitute nominees, discloses that such nominees have consented to being named in the revised proxy statement and to serve if elected, and includes certain biographical and other information about such nominees required by the rules of the SEC.

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 2027 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 2026 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.

PROPOSAL 3—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, 2026. 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, your broker may exercise discretionary authority, thereby avoiding a broker non-vote. 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.

PROPOSAL 4—STOCKHOLDER PROPOSAL REQUESTING
AN INDEPENDENT BOARD CHAIR POLICY
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 proposal and supporting statement are set forth below in the form that we received them, with the graphic added at his request:
Proposal 4—Independent Board Chairman
[MISSING IMAGE: ic_sharehold-4c.jpg]
Shareholders request that the Board of Directors adopt an enduring policy, and amend the governing documents as necessary in order that 2 separate people hold the office of the Chairman and the office of the CEO as soon as possible.
Selection of the Chairman of the Board the Board requires the separation of the offices of the Chairman of the Board and the Chief Executive Officer.
The Chairman of the Board shall be an Independent Director. A Lead Director shall not be a substitute for an independent Board Chairman.
The Board shall have the discretion to select an interim Chairman of the Board, who is not an Independent Director, to serve while the Board is seeking an Independent Chairman of the Board on an accelerated basis. This policy could be phased in when there is a contract renewal for our current CEO or for the next CEO transition.
Now is the perfect time to transition to an independent board chairman. Huntsman stock was at $41 in 2022. Huntsman stock then fell to $8 in late 2025. Huntsman stock was rated 4 for timeliness when 5 is the worst possible score.
An independent Board Chairman improves corporate governance by bringing impartiality, objective oversight, and external expertise to board decisions, mitigating conflicts of interest, enhancing transparency, and boosting investor confidence.
This detached perspective allows the chairman to focus on shareholder interests, strengthen management accountability, and provide critical checks and balances, ultimately contributing to the Company’s long-term sustainability and credibility.

BOARD OF DIRECTORS’ STATEMENT IN OPPOSITION
The Board is committed to strong corporate governance and responsiveness to the Company’s stockholders and believes in maintaining policies and practices that serve the best interests of all stockholders. The Board believes it is critically important to maintain the flexibility to implement the leadership structure best suited to meet the needs of the Company and its stockholders at any given time. The Board has carefully considered this proposal and concluded that adoption of the proposal is not in the best interests of the Company and its stockholders and is unnecessary given the current governance practices and protections.
Huntsman’s Board of Directors recommends a vote “AGAINST” Proposal 4 (the “Proposal”) for the following reasons:
The Board believes it is important to preserve flexibility on a case-by-case basis to determine the most effective leadership structure for the Company based on an assessment of the Company’s circumstances and needs at any given time.
Adopting a prescriptive policy and amending the Company’s governing documents to mandate an independent Chairman—as the Proposal asks the Board to do—would not serve the best interests of the Company or its stockholders. Such a policy would restrict the Board’s discretion to use its experience and judgment to select the most qualified and appropriate individual to serve as Chairman. Currently, our Corporate Governance Guidelines provide the Board with the flexibility to determine the optimal leadership structure, including separating the positions of Chairman and CEO if circumstances warrant. The Board believes our Company and our stockholders benefit from this flexibility, as our directors are well positioned to evaluate and determine our leadership structure given their knowledge of our leadership team, our strategic goals, the industry in which we operate and the opportunities and challenges we face.
The Board has concluded that, rather than taking a prescriptive, “one-size-fits-all” approach to its leadership structure, the Board’s fiduciary responsibilities are best fulfilled by retaining flexibility to determine the leadership structure that best serves the interests of the Company and its stockholders, considering the Company’s needs and circumstances at any given time.
The Company’s policies provide robust independent Board leadership and oversight of management in the event the Chairman is not independent.
Under our Corporate Governance Guidelines, the Board’s Lead Independent Director plays an important role in the Company’s governance structure, serving as the de facto leader of the independent directors, and is responsible for efficiently communicating with management on issues relevant to the independent directors and providing leadership on matters where potential conflicts of interest may be perceived to exist. The Lead Independent Director also serves as a primary Board contact for stockholders to communicate with the other independent directors.
Further, our Bylaws provide the Board with the flexibility to elect a Vice Chair of the Board 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 Vice Chair is also empowered to call special meetings of the Board upon request. Cynthia Egan has served as Lead Independent Director and Non-Executive Vice Chair of the Board since January 2022. In this role, she provides an effective balance to the Chairman role and contributes to a strong governance structure for the Board. Our Lead Independent Director and Non-Executive Vice Chair roles, as well as our other corporate governance practices described below, already provide robust independent leadership and impartial, objective oversight.
Combining the Chairman and CEO roles does not affect the Board’s oversight of critical matters.
Except for Mr. Huntsman, all directors are independent, and each committee of the Board is comprised entirely of independent directors, ensuring that independent directors have oversight of critical matters, such as the integrity of the Company’s financial statements (including internal controls over financial reporting), risk management, the compensation of executive officers, the nomination of directors and the development of corporate governance principles. In addition, under the Corporate Governance Guidelines and each committee’s charter, independent directors may retain independent legal, financial, accounting and other advisors as they deem necessary or appropriate. Further, pursuant to the Corporate Governance Guidelines, the independent directors meet in private sessions without management present at each regularly scheduled Board meeting, or more frequently as needed at the call of one or more of one or more of our independent directors, with the Lead Independent Director and Non-Executive Vice Chair presiding over such meetings.
The responsibilities of the full Board, together with the Board’s effective independent committee structure and the roles of the Lead Independent Director and Non-Executive Vice Chair, collectively allow the independent directors to carry out their fiduciary responsibilities to provide informed and effective oversight of the Company’s strategy and operations. As a result, the Board does not believe that a policy mandating an independent Chairman is necessary to achieve effective independent oversight.

HUNTSMAN CORPORATION: PROXY STATEMENT
​
​
Our strong and evolving corporate governance practices promote stockholder rights and accountability to stockholders.
The Board believes that the Company’s long-standing commitment to strong corporate governance principles makes the Proposal unnecessary. By responding to and implementing emerging governance best practices over the years, the Company maintains leading governance policies and procedures designed to promote stockholder rights and accountability to stockholders, including, among others:
•
the annual election of all directors;
​
•
a majority voting standard for director nominees in all uncontested elections, with advanced conditional resignation for failing to meet such majority vote;
​
•
simple majority stockholder voting requirements;
​
•
the ability of stockholders to remove directors, with or without cause;
​
•
the ability of stockholders to request special meetings of stockholders at the ownership threshold of 15%;
​
•
the ability of eligible stockholders to nominate director nominees through our proxy materials (proxy access);
​
•
no stockholder rights plan or “poison pill”;
​
•
annual “say-on-pay” advisory votes;
​
•
stock ownership guidelines for directors and executive officers;
​
•
a policy prohibiting short sales by directors and executive officers;
​
•
policies enhancing transparency in political giving and lobbying activities; and
​
•
regular outreach and engagement with our stockholders, including on corporate governance matters.
​
Reflecting the Board’s commitment to continuous improvement, the Board regularly reviews its governance practices to ensure they promote long-term stockholder value and effective functioning of the Board.
For the foregoing reasons, the Board believes that this Proposal is not in the best interests of Huntsman or our stockholders and recommends that you vote “AGAINST” Proposal 4.
THE BOARD RECOMMENDS VOTING ON THE PROXY CARD “AGAINST” THIS PROPOSAL

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
The following table presents information regarding beneficial ownership of our common stock as of March 6, 2026 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 March 6, 2026. 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 2025 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 2025 that involved amounts exceeding $120,000.

DELINQUENT SECTION 16(A) REPORTS
Section 16(a) of the Exchange Act requires our directors and executive officers, among others, to file with the SEC and the NYSE an initial report of ownership of our common stock on Form 3 and reports of changes in ownership on Form 4 or Form 5. Persons subject to Section 16 are required by SEC regulations to furnish us with copies of all Section 16 forms that they file related to Huntsman stock transactions. Under SEC rules, certain forms of indirect ownership and ownership of our common stock by certain family members are covered by these reporting requirements. As a matter of practice, our administrative staff assists our directors and executive officers in preparing initial ownership reports and reporting ownership changes and typically files these reports on their behalf.
Based solely on a review of the reports furnished to us or written representations from reporting persons that all reportable transactions were reported, we believe that during 2025 all of our executive officers, directors and greater than 10% holders filed the reports required to be filed under Section 16(a) on a timely basis under Section 16(a).
ANNUAL REPORT
The 2025 Annual Report is being furnished to our stockholders primarily via the Internet.
A copy of the 2025 Annual Report on Form 10-K for the year ended December 31, 2025, not including exhibits, is also available at www.huntsman.com. A copy of our Annual Report on Form 10-K for the year ended December 31, 2025, excluding exhibits, will be furnished at no charge to each person to whom a proxy statement is delivered upon the request of such person.

OTHER INFORMATION
​
DUPLICATE MAILINGS
​
If you share an address with other stockholders of the Company, you may receive notification that you are being sent only a single copy of the 2025 Annual Report and proxy materials, unless your bank, broker or other nominee that provides the notification receives contrary instructions from the affected stockholders. This practice, permitted under SEC rules and commonly referred to as “householding,” is designed to provide extra convenience for stockholders and potential cost savings for companies.
If, at any time, you no longer wish to participate in householding and would prefer to receive a separate set of the 2025 Annual Report and proxy materials, please notify (i) your broker if your shares of common stock are held in a brokerage account or (ii) the Company if you are a stockholder of record. We will promptly deliver a separate copy of the proxy materials, including the 2025 Annual Report, upon request. You can notify the Company by sending a written request to the attention of Corporate Secretary, 10003 Woodloch Forest Drive, The Woodlands, Texas 77380 or emailing [email protected] or by calling 281-719-6000.
Stockholders should direct communications regarding change of address, transfer of stock ownership or lost stock certificates by mail to Computershare Trust Company, N.A., P.O. Box 505000, Louisville, KY 40233-5000, or by telephone at 1-866-210-6997. Computershare may also be reached through its website at www.computershare.com.

ADDITIONAL DETAILS REGARDING THE ANNUAL MEETING
​
​
​
GENERAL
​
Annual Meeting Log-In Instructions
​
Because the Annual Meeting will be held virtually, there is no physical meeting location. To participate in the virtual Annual Meeting, holders of shares of our common stock as of the close of business on March 6, 2026 (the “Record Date”) should log in to the live webcast of the Annual Meeting at www.virtualshareholdermeeting.com/HUN2026.
To join the live webcast and participate in the virtual Annual Meeting (e.g., submit questions and/or vote your shares), you will need the 16-digit control number included on your proxy card and voting instruction form. Online access to the live webcast will open approximately 15 minutes prior to the start of the Annual Meeting. We recommend that you log in to the Annual Meeting several minutes before its scheduled start time.
If you are the representative of a trust or corporation, limited liability company, partnership or other legal entity that holds shares of our common stock, you will need the 16-digit control number included on the proxy card and voting instruction form of that legal entity in order to attend and participate in the virtual Annual Meeting.
No audio, video or other form of recording of the Annual Meeting is allowed. If you are not a stockholder at the close of business on the Record Date or do not have a control number, you will not be able to access the Annual Meeting.
​
Stockholder Access During The Annual Meeting
​
We are sensitive to the fact that virtual meetings provide a different forum than traditional in-person meetings and are committed to ensuring that stockholders will be afforded the same rights and opportunities to attend and participate in our virtual Annual Meeting as they would an in-person meeting. In particular, we believe the design of our virtual platform enhances, rather than constrains, stockholder access and participation. For example, our virtual platform will allow stockholders to vote their shares electronically during the live webcast and to submit questions for a live Q&A session that will be held at the end of the Annual Meeting.
​
Submitting Questions And Voting Your Shares At The Annual Meeting

QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING AND VOTING
​
1. What Is The Purpose Of The Annual Meeting?
​
At the Annual Meeting, stockholders will vote upon the matters outlined in the Notice of Annual Meeting of Stockholders, which are:
1.
To elect as directors nine nominees to serve until the 2027 Annual Meeting of Stockholders (the “2027 Annual Meeting”) or her/​his earlier resignation, removal or death.

​
4.
Stockholder proposal requesting an independent board chair policy.

To transact such other business as may properly come before the Annual Meeting in accordance with our Seventh Amended and Restated Bylaws of Huntsman Corporation (our “Bylaws”). The Board is not aware of any other matters to be presented at the Annual Meeting. In addition, our management will respond to questions from stockholders following the adjournment of the formal business at the Annual Meeting.
​
The Board recommends voting “FOR ALL” of the Board’s nominees on Proposal 1, “FOR” Proposal 2, “FOR” Proposal 3, and “AGAINST” Proposal 4 using the enclosed proxy card.
​
2. When And Where Will The Annual Meeting Be Held?
​
The Annual Meeting will be held on Wednesday, April 29, 2026, at 8:00 a.m. Central Time by virtual meeting at www.virtualshareholdermeeting.com/HUN2026 for the purposes set forth in the accompanying Notice of Annual Meeting.
Attendance at the Annual Meeting will be limited to stockholders as of the close of business on the Record Date and/or their authorized representatives, and guests of the Company. Even if you plan to attend the virtual Annual Meeting, we strongly urge you to vote in advance by voting via the Internet, by telephone or by completing, signing, and dating the enclosed voting instruction form or proxy card and returning it in the postage pre-paid envelope provided, as soon as possible.
​

The Company’s proxy materials include: (1) the Notice of Annual Meeting of Stockholders; (2) this Proxy Statement; (3) the 2025 Annual Report; and (4) a proxy card or a voting instruction card for the Annual Meeting.
You may refer to the 2025 Annual Report for financial and other information about our operations. The 2025 Annual Report is not incorporated by reference into this Proxy Statement and is not deemed to be a part hereof.
​
4. WHAT Is A PROXY?
​
A proxy is your legal designation of another person to vote the stock you own. That other person is called a proxy. If you designate someone as your proxy in a written document, that document also is called a proxy or a proxy card. Peter R. Huntsman, our Chairman of the Board, President and Chief Executive Officer, also referred to herein as our “CEO,” and Amy K. Smedley, our Executive Vice President, General Counsel and Secretary, will serve as proxies for the Annual Meeting pursuant to the proxy cards solicited by our Board.
​
5. WHAT Is A PROXY STATEMENT?
​
A proxy statement is a document that the regulations of the U.S. Securities and Exchange Commission (the “SEC”) require us to give you when we ask that you designate Peter R. Huntsman and Amy K. Smedley as proxies to vote on your behalf. This Proxy

​
HUNTSMAN CORPORATION: PROXY STATEMENT
​
​
Statement includes information about the proposals to be considered at the Annual Meeting and other required disclosures, including information about the Board and our executive officers.
​
6. How Can I Access The Proxy Materials Over The Internet?
​
Your proxy card contains instructions on how to:
•
view our proxy materials online at www.proxyvote.com; and
​
•
instruct us to send future proxy materials to you electronically by e-mail.
​
If you choose to access future proxy materials electronically, you will receive an e-mail with instructions containing a link to the website where those materials are available and a link to the proxy voting website. Your election to access proxy materials by e-mail will remain in effect until you terminate it.
​
7. What Is The Record Date And What Does It Mean?
​
The Record Date for the Annual Meeting is March 6, 2026. Owners of record of our common stock, par value $0.01 per share (“common stock”) at the close of business on the Record Date are entitled to:
•
receive notice of the Annual Meeting; and
​
•
vote at the Annual Meeting in accordance with our Bylaws.
​
At the close of business on March 6, 2026, there were 173,976,139 shares of our common stock outstanding, each of which is entitled to one vote on each item of business to be conducted at the Annual Meeting. At the Annual Meeting, stockholders will collectively be able to cast 173,976,139 votes, consisting of one vote for each share of common stock outstanding on the Record Date. There is no cumulative voting, and the holders of the common stock vote together as a single class. Stockholders do not have appraisal rights under Delaware law in connection with this proxy solicitation.
​
8. Who May Attend The Annual Meeting?
​
All stockholders of record who owned shares of common stock on the Record Date or their duly appointed proxies may attend the Annual Meeting, as may our invited guests. To join the live webcast and participate in the virtual Annual Meeting (e.g., submit questions and/or vote your shares), you will need the 16-digit control number included on your proxy card, voting instruction form. Online access to the live webcast will open approximately 15 minutes prior to the start of the Annual Meeting. We recommend that you log in to the Annual Meeting several minutes before its scheduled start time.
If you are not a stockholder at the close of business on March 6, 2026 (the Record Date for the Annual Meeting) or do not have a control number, you will not be able to access the Annual Meeting.
​
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 86,988,070 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.

​ HUNTSMAN CORPORATION: PROXY STATEMENT ​
​
•
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 and 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 nine of the director nominees recommended by the Board;
​
•
FOR approval, on a non-binding advisory basis, of 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, 2026; and
​
•
AGAINST approval of the stockholder proposal requesting an independent board chair policy.
​
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 the 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 3) 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 and 4 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 and 4.
​
14. What Votes Are Needed For Each Proposal To Pass And Is Broker Discretionary Voting Allowed?

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 [email protected]; or
​
•
attending the Annual Meeting and voting in person (merely attending the Annual Meeting will not revoke a prior submitted proxy).
​
If you are a street name stockholder, you must follow the instructions to revoke your proxy, if any, provided by your bank, broker or other nominee.

RECONCILIATION OF NON-GAAP
FINANCIAL MEASURES
​
​
​
The 2026 Proxy Statement includes information on adjusted EBITDA 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.
