HUN Huntsman Corporation

APPROVAL OF BOARD'S PROPOSAL TO ALLOW STOCKHOLDERS TO REQUEST SPECIAL MEETINGS OF STOCKHOLDERS (PROPOSAL 5)

In Proposal No. 5, we are seeking approval of the Board's proposal to allow stockholders to request special meetings of stockholders. The Board believes that providing stockholders with the right to ask the Company to call a special meeting can be an important corporate governance practice that enhances stockholder rights. It is well recognized, however, that an unlimited or unrestrained right to call for a special meeting, an extraordinary event for any public company, can be disruptive, costly, and inconsistent with the best interests of all of the stockholders. Therefore, the Board is proposing that holders of 25% of the stock in the aggregate who satisfy certain procedures and requirements have the right to request a special meeting of stockholders.

HUNTSMAN CORPORATION PROXY STATEMENT

This Proxy Statement is being furnished to the stockholders of Huntsman Corporation in connection with the solicitation of proxies by its Board of Directors (the "Board"). The proxies are to be voted at our 2016 Annual Meeting of Stockholders (the "Annual Meeting") to be held at The Westin The Woodlands, 2 Waterway Square Place, The Woodlands, Texas 77380, at 8:30 a.m., local time, on May 5, 2016, and any adjournments or postponements thereof, for the purposes set forth in the accompanying Notice of Annual Meeting.

The Board is soliciting your proxy to vote your shares at the Annual Meeting. We will bear the cost of the solicitation, including the cost of the preparation, assembly, printing and, where applicable, mailing of the Notice of Annual Meeting of Stockholders, this Proxy Statement, the proxy card, the Notice of Internet Availability of Proxy Materials (the "Notice of Internet Availability") and any additional information furnished by us to our stockholders. In addition to solicitation by mail, certain of our directors, officers and employees may, without extra compensation, solicit proxies by telephone, facsimile, electronic means and personal interview. We have retained D.F. King & Co., Inc. to help us distribute and solicit proxies and have agreed to pay them $14,500, plus reimbursement for out-of-pocket expenses, for these services. We will also make arrangements with brokerage houses, custodians, nominees and other fiduciaries to send proxy materials to their principals, and we will reimburse them for postage and clerical expenses.

DELIVERY OF PROXY MATERIALS

On or about March 25, 2016, we mailed a Notice of Internet Availability to our stockholders of record and beneficial owners who owned shares of our common stock at the close of business on March 11, 2016. The Notice of Internet Availability contained instructions on how to access the proxy materials and vote online. We have made these proxy materials available to you over the Internet or, upon your request, have delivered paper versions of these materials to you by mail, in connection with the solicitation of proxies by our Board for the Annual Meeting.

Choosing to receive your future proxy materials by e-mail will save us the cost of printing and mailing documents to you. If you choose to receive future proxy materials by e-mail, you will receive an e-mail next year with instructions containing a link to those materials and a link to the proxy voting site.

3. 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 President and Chief Executive Officer (our "CEO"), and David M. Stryker, our Executive Vice President, General Counsel and Secretary, will serve as proxies for the Annual Meeting pursuant to the proxy card solicited by our Board.

4. 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 David M. Stryker as proxies to vote on your behalf. This Proxy 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.

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.

6. WHAT IS THE RECORD DATE AND WHAT DOES IT MEAN?

The record date for the Annual Meeting is March 11, 2016. Owners of record of our 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 and any adjournments or postponements in accordance with our Bylaws.

At the close of business on March 11, 2016, there were 238,165,673 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.

7. WHO MAY ATTEND THE ANNUAL MEETING?

All stockholders of record who owned shares of common stock at the close of business on March 11, 2016, or their duly appointed proxies, may attend the Annual Meeting and any adjournments or postponements thereof, as may our invited guests. "Street name stockholders," as described in Question 10 below, who owned shares of common stock at the close of business on March 11, 2016, may also attend subject to the requirements set forth in Questions 10 and 11 below. Seating is limited and admission is on a first-come, first-served basis. If you attend the Annual Meeting, you will need to bring your Notice of Internet Availability or proxy card, as applicable, a form of personal identification (such as a driver's license) and check in at the registration desk at the Annual Meeting. Please note that if you hold shares in "street name" (that is, in a brokerage account or through a bank or other nominee), you also will need to bring a copy of a statement reflecting your share ownership as of March 11, 2016.

8. 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 119,082,837 shares of our common stock is

Table of Contents

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.

9. 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, with respect to those shares, the "stockholder of record." As the stockholder of record, you have the right to grant your voting proxy directly or to vote in person at the Annual Meeting.

•

Street Name Stockholders.   If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered, with respect to those shares, the beneficial owner of shares held in "street name," and the Notice of Internet Availability or proxy materials are being forwarded to you by your broker, bank or other nominee, which is considered, with respect to those shares, the stockholder of record. As the beneficial owner, you have the right to instruct your broker, bank or other nominee how to vote and you are also invited to attend the Annual Meeting. However, since you are not the stockholder of record, you may not vote these shares in person at the Annual Meeting unless you obtain a signed proxy from the stockholder of record giving you the right to vote the shares. Your broker, bank or other or nominee has provided voting instructions for you to use in directing the broker, bank or other or nominee how to vote your shares. If you fail to provide sufficient instructions to your broker, bank or other nominee or nominee, they may be prohibited from voting your shares. See "If I am a street name holder, will my shares be voted if I do not provide my proxy?"

10. 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 proxy card or Notice of Internet Availability. Please have your proxy card or Notice of Internet Availability in hand when you log onto the website. Internet voting facilities will be available 24 hours a day and will close at 11:59 p.m., Eastern Daylight Time, on May 4, 2016.

•

By Telephone.    You may submit a proxy by telephone (from U.S. and Canada only) using the toll-free number listed on the proxy card or Notice of Internet Availability. Please have your proxy card or Notice of Internet Availability in hand when you call. Telephone voting facilities will be available 24 hours a day and will close at 11:59 p.m., Eastern Daylight Time, on May 4, 2016.

•

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 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.

•

In Person with a Proxy from the Record Holder.     You may vote in person at the Annual Meeting if you obtain a legal proxy from your bank, broker or other nominee. Please consult the voting instruction form or other information sent to you by your bank, broker or other nominee to determine how to obtain a legal proxy in order to vote in person at the Annual Meeting.

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

EVEN IF YOU PLAN TO ATTEND THE ANNUAL MEETING, WE RECOMMEND YOU ALSO SUBMIT YOUR PROXY SO THAT YOUR VOTE WILL COUNT IF YOU ARE UNABLE TO ATTEND THE MEETING. SUBMITTING YOUR PROXY VIA INTERNET, TELEPHONE OR MAIL DOES NOT AFFECT YOUR ABILITY TO VOTE IN PERSON AT THE ANNUAL MEETING.

Table of Contents

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

A 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 proxy, but do not indicate any contrary voting instructions, your shares will be voted as follows:

•

FOR the election of the six Class I director nominees named in this Proxy Statement;

•

FOR approval, on a non-binding advisory basis, of the compensation of our named executive officers;

•

FOR the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2016;

•

FOR approval of the Huntsman 2016 Stock Incentive Plan;

•

FOR approval of the Board's proposal to allow stockholders to request special meetings of stockholders;

•

AGAINST the stockholder proposal to allow stockholders to request special meetings; and

•

AGAINST the stockholder proposal regarding majority voting for the election of directors.

If any other business properly comes before the stockholders for a vote at the meeting, your shares will be voted at the discretion of the holders of the proxy. The Board knows of no matters, other than those previously described, to be presented for consideration at the Annual Meeting.

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

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 firms is 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." The election of directors and the advisory vote to approve named executive officer compensation are not considered routine matters. Therefore, if you are a street name stockholder and 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 will have no effect on the outcome of these proposals.

14. 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. Under Rule 14a-8 and the provisions of our Bylaws, 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.

15. 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 prior to 11:59 p.m. Eastern Daylight Time on May 4, 2016;

•

requesting, completing and mailing in a new paper proxy card, as outlined in the Notice of Internet Availability;

•

giving written notice of revocation to our Corporate Secretary by mail to Corporate Secretary, 10003 Woodloch Forest Drive, The Woodlands, Texas 77380 or by facsimile at (281) 719-4500; or

•

attending the Annual Meeting and voting in person.

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.

Table of Contents

16. WHAT DOES IT MEAN IF I RECEIVE MORE THAN ONE NOTICE OF INTERNET AVAILABILITY OR MORE THAN ONE SET OF PROXY MATERIALS?

It means that you have multiple accounts with our transfer agent, Computershare, and/or brokers, banks or other nominees. Please vote all of your shares. We recommend that you contact Computershare and/or your broker, bank or other nominee (as applicable) to consolidate as many accounts as possible under the same name and address. If you have multiple accounts with Computershare that you want to consolidate, please submit your request by mail to Computershare Trust Company, N.A., P.O. Box 30170, College Station, TX, 77842, or by telephone at 1-866-210-6997.
