Item 5.03.                Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On December 21, 2016, the Board of Directors (the “Board”) of Huntsman Corporation (the “Company”) approved the amendment and restatement of the bylaws of the Company (the “Bylaws”), effective as of such date.

The Bylaws were amended to permit a shareholder, or a group of up to 20 shareholders (with funds having specified relationships constituting a single shareholder), who own (as defined in the Bylaws) three percent or more of the Company’s outstanding common stock continuously for at least three years, to nominate and include in the Company’s proxy materials director candidates constituting up to two directors or 20% of the Board (rounded down to the nearest whole number), whichever is greater, provided that the shareholder(s) and the nominee(s) satisfy the requirements specified in the Bylaws.

The Bylaws were also amended to provide that stockholders who collectively own (as defined in the Bylaws) at least 25% of the Company’s outstanding shares of common stock continuously for at least 365 consecutive dates and who satisfy certain other requirements may have the Company call a special meeting of stockholders for certain purposes.

In addition, the Bylaws were amended to (a) revise the voting standards for director elections from a plurality vote standard for all director elections to (i) a majority vote standard for elections other than “Contested Elections” (as defined in the Bylaws) or (ii) a plurality vote standard for Contested Elections, as applicable; and (b) adopt a director resignation policy such that, in order for any incumbent director to become a nominee of the Board, such person must submit an irrevocable resignation, contingent on (i) that person not receiving a majority of the votes cast in an election that is not a Contested Election and (ii) acceptance of that proffered resignation by the Board.

The amendments also include various updates, wording changes and clarifications.

The foregoing description of the Bylaws is qualified in its entirety by reference to the full text of the Bylaws, a copy of which is attached hereto as Exhibit 3.1 and incorporated herein by reference.
