Item 5.07

Submission of Matters to a Vote of Security Holders

As previously disclosed, on June 15, 2026, Olin Corporation, a Virginia corporation (“Olin”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Huntsman Corporation, a Delaware corporation (“Huntsman”), Olympus Merger Sub, Inc., a Delaware corporation and a direct wholly owned subsidiary of Olin (“First Merger Sub”), and Hook Merger Sub LLC, a Delaware limited liability company and a direct wholly owned subsidiary of Olin (“Second Merger Sub”), providing for, on the terms and subject to the conditions included in the Merger Agreement, the merger of equals business combination of Olin and Huntsman, either (a) through the merger of Huntsman with and into Olin, with Olin as the surviving entity (the “Direct Merger”), or (b) through (i) the merger of First Merger Sub with and into Huntsman (the “First Subsidiary Merger”), with Huntsman surviving as a direct, wholly owned subsidiary of Olin (the “Initial Surviving Company”), and (ii) immediately following the First Subsidiary Merger, and as part of the same overall transaction as the First Subsidiary Merger, the Initial Surviving Company will be merged with and into Second Merger Sub (the “Second Subsidiary Merger” and, together with the First Subsidiary Merger, the “Subsidiary Merger”), with Second Merger Sub surviving as a direct wholly owned subsidiary of Olin (we collectively refer to the Direct Merger and the Subsidiary Merger as the “Merger”).

On August 25, 2026, Olin held a virtual special meeting of its shareholders (the “Special Meeting”) to vote on the proposals identified in the definitive joint proxy statement/prospectus filed with the U.S. Securities and Exchange Commission (the “SEC”) on July 13, 2026, which was first mailed to Olin’s shareholders on or about July 13, 2026.

Each shareholder of record was entitled to one vote per share of common stock on each proposal. As of the close of business on July 9, 2026, the record date for the Special Meeting, there were 113,982,490 shares of common stock, par value $1.00 per share, of Olin (“Olin Common Stock”) issued and outstanding and entitled to vote at the Special Meeting. 95,428,141 shares of Olin Common Stock, representing approximately 84% of all of Olin Common Stock issued and outstanding and entitled to vote at the Special Meeting as of the record date, were present or represented by proxy at the Special Meeting, constituting a quorum to conduct business. The final voting results with respect to each proposal are set out below:

Proposal 1 – Approve the Direct Merger

The proposal to approve the Merger Agreement and the related plan of merger providing for the Direct Merger, including the issuance of shares of Olin Common Stock in connection with the Direct Merger (the “Direct Merger Proposal”). Olin’s shareholders approved the Direct Merger Proposal as follows:

Votes For

Votes Against

Votes Abstained

Broker Non-Votes

92,038,804

3,111,350

277,987

The proposal to approve the issuance of shares of Olin Common Stock in connection with the Subsidiary Merger (the “Subsidiary Merger Proposal”). Olin’s shareholders approved the Subsidiary Merger Proposal as follows:

Votes For

Votes Against

Votes Abstained

Broker Non-Votes

91,954,959

3,190,072

283,110

Proposal 3 – Conduct an advisory vote to approve the compensation for named executive officers

The proposal to approve, on a non-binding, advisory basis, the compensation that may be paid or become payable to Olin’s named executive officers that is based on or otherwise relates to the transactions contemplated by the Merger Agreement. Olin’s shareholders approved the proposal as follows:

Votes For

Votes Against

Broker Non-Votes

87,862,384

7,105,019

460,738

In connection with the Special Meeting, Olin also solicited proxies with respect to the approval of one or more adjournments of the Special Meeting to a later date or time, if necessary or appropriate, including adjournments to permit the solicitation of additional votes or proxies if there were not sufficient votes cast at the Special Meeting to approve the Direct Merger Proposal or the Subsidiary Merger Proposal (the “Adjournment Proposal”). As there were sufficient votes at the time of the Special Meeting to approve the Direct Merger Proposal and the Subsidiary Merger Proposal, the Adjournment Proposal was unnecessary and such proposal was not submitted to the shareholders for approval at the Special Meeting.

Item 7.01

today announced that their respective shareholders have approved the proposals necessary to complete the companies’ previously announced all-stock merger of equals.

“We greatly appreciate the strong support of Olin and Huntsman shareholders as we reach this important milestone,” said Ken Lane,

President and Chief Executive Officer of Olin. “OlinHuntsman Corporation will be a more value-focused chemicals company with a world-scale vertically integrated platform that is better positioned to serve customers across the value chain and

deliver resilient financial performance. We are committed to completing the remaining steps to close the transaction, and to delivering long-term value for our shareholders, customers, employees, and communities as one company.”

“OlinHuntsman will be better positioned to compete in an increasingly global industry, delivering value, adding products and greater

service for customers,” said Peter Huntsman, Chairman, President and Chief Executive Officer of Huntsman. “We thank our shareholders for the overwhelming support at the special meeting and look forward to completing this combination and

getting to work building a global chemicals leader.”

Based on preliminary voting results, at the special meeting of Olin

shareholders held today, approximately 97% of the votes cast, representing 81% of all outstanding shares, were voted in favor of the consummation of the transaction through a direct merger of Olin and Huntsman. At the special meeting of Huntsman

stockholders held today, approximately 99% of the votes cast, representing 75% of all outstanding shares, were voted in favor of the merger based on preliminary voting results.

Based on these preliminary voting results, subject to the satisfaction of other closing conditions, the transaction will proceed through a direct

merger of Olin and Huntsman.

The final voting results are subject to certification by the companies’ respective independent

inspectors of elections and will be reported in separate Current Reports on Form 8-K filed by Olin and Huntsman with the U.S. Securities and Exchange Commission. The transaction is expected to close in the

first half of 2027 and remains subject to the receipt of required regulatory approvals and the satisfaction or waiver of other customary closing conditions.

confidential information through artificial intelligence tools; (j) risks associated with Olin’s and/or Huntsman’s international sales and operations, including economic, political or regulatory changes; (k) weak industry

conditions affecting Olin’s and/or Huntsman’s ability to comply with the financial maintenance covenants in its debt agreements; (l) Olin’s and/or Huntsman’s indebtedness and debt service obligations; (m) failure to

release speaks only as of the date of this communication. Neither Olin nor Huntsman undertake any obligation to update publicly any forward-looking statements, or any other information in this release whether as a result of future events, new

information or otherwise, or to correct any inaccuracies or omissions in them which become apparent. All forward-looking statements in this communication are qualified in their entirety by this cautionary statement.
