Olin Corporation and Huntsman Corporation have entered into a definitive agreement to combine in an all-stock merger, creating one of North America’s largest integrated chemical companies with annual revenue exceeding $12.5 billion. The transaction brings together two established industry players with complementary manufacturing, feedstock, and specialty chemicals capabilities, positioning the combined business for stronger growth, improved efficiency, and enhanced competitiveness across global markets.
Following completion of the transaction, the combined company will operate under the name OlinHuntsman Corporation. The merger is designed to strengthen vertical integration by combining Olin’s large-scale upstream chemical production capabilities with Huntsman’s downstream specialty products, formulations, and advanced materials expertise.
The combined organization will serve a diverse range of industries including automotive, construction, infrastructure, industrial manufacturing, and advanced materials. With a significant manufacturing footprint across North America, particularly along the US Gulf Coast, and an established presence in Europe and Asia, the company expects to benefit from greater operational flexibility and broader customer reach.
The companies have identified more than $400 million in anticipated cost synergies and integration benefits. A substantial portion of these savings is expected to be realized within the first two years following completion of the merger. The benefits are expected to arise from procurement efficiencies, raw material integration, operational optimization, and administrative cost reductions. Additional long-term benefits are also expected through improved feedstock utilization and greater value creation across the chemical value chain.
Ken Lane, President and Chief Executive Officer of Olin, said the combination creates a stronger and more resilient business capable of delivering improved performance across market cycles. He noted that integrating Olin’s manufacturing strengths with Huntsman’s differentiated product portfolio would create new opportunities for growth, customer support, and value creation.
Peter Huntsman, Chairman, President and Chief Executive Officer of Huntsman, described the transaction as a significant step toward building a stronger global competitor in an increasingly interconnected and competitive chemical industry. He emphasized that the merger enhances the ability of both organizations to serve customers while creating greater long-term value for shareholders and employees.
Upon closing, Ken Lane will serve as Chief Executive Officer of OlinHuntsman, while Peter Huntsman will become Non-Executive Chairman of the Board. The company will be headquartered in The Woodlands, Texas. The Board of Directors will consist of equal representation from both companies.
Under the agreed terms, Huntsman shareholders will receive 0.5476 shares of Olin for each Huntsman share held. Upon completion, Olin shareholders will own approximately 54.5 percent of the combined company, while Huntsman shareholders will own approximately 45.5 percent. The transaction has received unanimous approval from both boards and is expected to close during the first half of 2027, subject to shareholder approvals, regulatory clearances, and customary closing conditions.
