Olin and Huntsman Agree Landmark Merger to Create $12.5 Billion North American Chemicals Leader

Olin Corporation and Huntsman Corporation have announced a transformative merger of equals that will create a leading North American chemicals company with combined annual revenues exceeding US$12.5 billion.

The merged entity, to be named OlinHuntsman Corporation, will combine Olin’s large-scale upstream chemical and chlor-alkali operations with Huntsman’s downstream portfolio of polyurethanes, advanced materials and speciality chemical formulations. The companies stated that the transaction is expected to generate more than US$400 million in identified cost synergies and integration benefits, including savings from raw material integration, procurement efficiencies, operational optimisation and reduced administrative costs.

The merger is designed to strengthen vertical integration across the value chain, enabling the combined company to convert advantaged chlorine and caustic soda production into higher-value downstream products while improving profitability and cash flow throughout market cycles. OlinHuntsman is expected to benefit from a broader manufacturing footprint, particularly along the U.S. Gulf Coast, while also enhancing its presence in Europe and Asia.

Under the agreement, Olin shareholders will own approximately 54.5% of the combined company, while Huntsman shareholders will hold the remaining 45.5%. Current Olin President and Chief Executive Officer Ken Lane will lead the merged organisation as CEO, while Huntsman Chairman, President and CEO Peter Huntsman will serve as non-executive Chairman of the Board.

The new company will be headquartered in The Woodlands, Texas. Both companies believe the combination will create a more resilient and competitive enterprise capable of delivering stronger shareholder returns, greater operational flexibility and enhanced customer service across automotive, construction, infrastructure and industrial markets. The transaction has received unanimous board approval from both companies and is expected to close during the first half of 2027, subject to shareholder and regulatory approvals.
