Olin and Huntsman Shareholders Approve Merger of Equals

The all-stock combination of the two chemicals makers is expected to close in the first half of 2027.

Olin Corporation (OLN) and Huntsman Corporation (HUN) said their shareholders approved the proposals needed to complete a previously announced all-stock merger of equals, clearing the last major corporate vote before the deal is expected to close in the first half of 2027.

Based on preliminary results, about 97% of the votes cast at Olin’s special meeting, representing 81% of all outstanding shares, were in favor of a direct merger of the two companies. At Huntsman’s special meeting, about 99% of the votes cast, representing 75% of all outstanding shares, supported the combination. Subject to other closing conditions, the transaction will proceed through that direct merger, with Olin as the surviving entity.

The companies agreed on June 15, 2026, to combine in an all-stock merger of equals to create a chemicals company they described as a $12-plus-billion integrated North American leader. The combined organization, to be renamed OlinHuntsman Corporation after closing, was expected to benefit from enhanced scale, scope and expanded chlorine optionality, pairing Olin’s cost-advantaged electrochemical assets with Huntsman’s formulations and advanced materials. The deal was expected to generate more than $400 million in identified cost synergies and integration benefits.

Ken Lane, president and chief executive officer of Olin, said the combined company “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.” He said the companies are committed to completing the remaining steps to close and to delivering long-term value for shareholders, customers, employees and communities as one company.

Peter Huntsman, chairman, president and chief executive officer of Huntsman, said OlinHuntsman “will be better positioned to compete in an increasingly global industry, delivering value, adding products and greater service for customers.” He thanked shareholders for their support at the special meeting and said the company looks forward to completing the combination and building a global chemicals leader.

Olin is a vertically integrated global manufacturer and distributor of chemical products, including chlorine and caustic soda, vinyls, epoxies, chlorinated organics, bleach, hydrogen and hydrochloric acid, and a leading U.S. manufacturer of ammunition through Winchester. Huntsman is a global manufacturer and marketer of diversified chemical products with 2025 revenues of approximately $6 billion from continuing operations, more than 55 manufacturing, R&D and operations facilities in about 25 countries, and approximately 6,000 associates.

Final voting results are subject to certification by the companies’ independent inspectors of elections and will be reported in separate Current Reports on Form 8-K filed with the U.S. Securities and Exchange Commission. The transaction remains subject to required regulatory approvals and the satisfaction or waiver of other customary closing conditions.
