Olin and Huntsman to Merge in $12.5 Billion Chemicals Deal

The new entity, to be renamed OlinHuntsman Corporation, will unite Olin’s scale in chlorine and caustic soda production with Huntsman’s specialized portfolio of polyurethane systems and advanced materials. By combining these upstream assets with downstream formulation expertise, the company expects to gain greater cost-efficiency and flexibility across global markets, including automotive and infrastructure sectors.

Ken Lane, currently CEO of Olin, will lead the combined organization as Chief Executive Officer, while Peter Huntsman will serve as non-executive Chairman of the Board. The transaction, which has received unanimous approval from both boards, is structured as a merger of equals. Under the terms, Huntsman shareholders will receive 0.5476 shares of Olin for every share held, resulting in Olin shareholders owning approximately 54.5% of the new company. Headquartered in The Woodlands, Texas, the deal is expected to close in the first half of 2027, pending regulatory and shareholder approvals.
