EXPLANATORY NOTE

This Statement on Schedule 13D, as amended as of the date hereof (this “Statement”), is being filed by The Huntsman Foundation, a Utah nonprofit corporation (“Huntsman Foundation”). Huntsman Foundation, is sometimes referred to as the “Reporting Person.”  In this Schedule 13D, the “Company” refers to Huntsman Corporation, a Delaware corporation, and “Shares” refers to shares of Common Stock, $0.01 par value per share, of the Company.

This Statement is filed pursuant to Rule 13d-1(k) promulgated by the Securities and Exchange Commission (the “Commission”) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).  The amended and restated Schedule 13D (Amendment No. 15) filed by (i) Huntsman Foundation, (ii) Huntsman Family Holdings Company LLC, a Utah limited liability company (“Huntsman Family Holdings”), (iii) P&B Capital, L.C., a Utah limited liability company (“P&B”), (iv) Jon M. Huntsman (“J. Huntsman”) and (v) Peter R. Huntsman (“P. Huntsman”) on November 30, 2017 (the “A&R Schedule 13D”) should be read together with this Statement. Unless otherwise indicated herein, all capitalized terms used herein shall have the meanings given to them in the A&R Schedule 13D.

Item 2. Identity and Background.

Item 2 is deleted in its entirety and restated as follows:

This Statement is filed by the Reporting Person. Huntsman Foundation, Huntsman Family Holdings, P&B, J. Huntsman and P. Huntsman were previously parties to a Joint Filing Agreement dated May 30, 2017 (the “2017 Joint Filing Agreement”), pursuant to which such parties agreed to jointly file with the Securities and Exchange Commission the Schedule 13D and any and all amendments thereto.  The 2017 Joint Filing Agreement and the agreement of the parties thereto to participate as members of a “group” (within the meaning of Section 13(d)(3) of Exchange Act) were terminated by a Termination Agreement, dated April 11, 2018 (the “Termination Agreement”).  The Termination Agreement is filed herewith as Exhibit 99.1 and is incorporated herein by reference.

As a result of the matters described in this Statement, none of Huntsman Family Holdings, P&B, the Estate of Jon M. Huntsman (the “Estate”) and P. Huntsman beneficially own more than five percent (5%) of the Shares or other securities of the Company.  Therefore, Huntsman Family Holdings, P&B, the Estate and P. Huntsman are no longer required to file statements on Schedule 13D with respect to their beneficial ownership of Shares or other securities of the Company.  Huntsman Foundation will continue filing statements on Schedule 13D with respect to its beneficial ownership of securities of the Company to the extent required by applicable law.

Huntsman Foundation’s principal business is to support the Huntsman Cancer Institute (HCI) of the University of Utah. The name, business address, present principal occupation or employment and citizenship of each director and executive officer of Huntsman Foundation are set forth in Schedule A.
