Huntsman Corporation and Olin Corporation report that the U.S. SEC declared effective Olin’s registration statement on Form S-4 for their previously announced all-stock merger of equals to form OlinHuntsman. The companies state the combination is expected to create a leading North American chemicals company with enhanced vertical integration and expanded chlorine optionality.
Special meetings for Olin shareholders and Huntsman stockholders to vote on the transaction are scheduled for August 25, 2026, with a record date of July 9, 2026. Completion of the merger is expected in the first half of 2027, subject to regulatory approvals and approval by both companies’ owners. Huntsman reports approximately $6 billion in 2025 revenues from continuing operations, with more than 55 facilities in about 25 countries.
Olin Corporation and Huntsman Corporation plan a stock-for-stock merger of equals, effected either by a direct merger of Huntsman into Olin or a two-step subsidiary merger. Each Huntsman share will convert into 0.5476 shares of Olin common stock, with cash paid instead of fractional shares.
Based on Olin’s July 9, 2026 closing price, this consideration equaled about $11.06 per Huntsman share. Olin shareholders vote on direct and subsidiary merger structures, related compensation and adjournment proposals; Huntsman stockholders vote on adopting the merger agreement, compensation and adjournment. The combination will proceed if Huntsman stockholders approve the merger proposal and Olin shareholders approve at least one merger structure.
Both boards unanimously support the transaction. Governance of the combined company will be shared, with Olin’s CEO Kenneth T. Lane as CEO and Huntsman’s CEO Peter R. Huntsman as non-executive chair, plus a balanced board and committees. If the subsidiary structure is used, Huntsman’s 2.950% 2031 and 4.500% 2029 notes will likely be refinanced at higher rates, increasing interest expense and reducing net income relative to the direct merger structure. Huntsman shares will be delisted, and the combined company will trade on NYSE under a new name and ticker.
