On August 25, 2026, the Company held a special meeting of stockholders (the “Special Meeting”) to vote on the proposals identified in the definitive proxy statement filed with the U.S. Securities and Exchange Commission (the “SEC”) on July 13, 2026, which was first mailed to the Company’s stockholders on or about July 13, 2026.
American Election Services, LLC, the independent inspector of the elections (the “Inspector of Election”) for the Special Meeting, delivered its final vote tabulation on August 25, 2026 that certified the final voting results for each of the matters that were submitted to a vote at the Special Meeting. Set forth below are the final voting results as provided by the Inspector of Election.
Each stockholder 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 175,381,417 shares of common stock issued and outstanding and entitled to vote at the Special Meeting. Present at the Special Meeting in person or by proxy were holders of shares of common stock representing an aggregate of 133,710,141 votes, or 76.23% of the voting power entitled to vote at the Special Meeting as of the record date, constituting a quorum. The final voting results with respect to each proposal are set out below:
1. To adopt the Merger Agreement providing for the business combination of Huntsman and Olin either through the Direct Merger or the Subsidiary Merger and the other transactions contemplated thereby (the “Huntsman Merger Proposal”).
| For | Against | Abstain | ||||||||

As there were sufficient votes at the time of the Special Meeting to approve the Merger Proposal, the Adjournment Proposal was unnecessary and such proposal was not submitted to the stockholders for approval at the Special Meeting.
