Olin Corporation and Huntsman Corporation have entered a definitive agreement to merge in an all-stock transaction, creating a North American chemical powerhouse with approximately $12.5 billion in combined annual revenue. The deal, which establishes a new entity to be named OlinHuntsman, aims to leverage $400 million in identified cost synergies and vertical integration to improve performance across market cycles, according to the official joint announcement released on June 16, 2026.
How does vertical integration change chemical manufacturing?
Vertical integration allows a company to control more of its supply chain, from raw material extraction to the production of high-value end products. By combining Olin’s expertise in chlorine and caustic soda production with Huntsman’s downstream formulation and advanced materials portfolio, the new entity expects to reduce its cost position. According to company leadership, this structure enables the conversion of Electrochemical Units (ECUs) directly into higher-margin materials, effectively insulating the business against volatility in commodity chemical prices.
The merger is expected to generate $125 million in cash tax benefits through the acceleration of Net Operating Losses, in addition to the $400 million in operational synergies.
What are the financial implications for shareholders?
The transaction is structured as an all-stock merger of equals, with Olin shareholders owning approximately 54.5% of the combined company and Huntsman shareholders holding 45.5%. According to Peter Huntsman, Chairman and CEO of Huntsman, the exchange ratio was determined using a 30-day volume-weighted average price as of June 12, 2026. This approach was intended to provide a premium to Huntsman shareholders while remaining equitable to Olin investors amidst market fluctuations. The combined firm plans to prioritize a stable dividend policy and disciplined capital allocation to support both maintenance and future growth projects.
How will leadership and governance be structured?
The post-merger leadership team draws from both organizations to ensure continuity and oversight. Ken Lane, the current CEO of Olin, will serve as the Chief Executive Officer of OlinHuntsman. Peter Huntsman will transition to the role of non-executive Chairman of the Board. The board itself will consist of ten members, with equal representation from both original companies. Additionally, Olin’s current CFO, Todd Slater, will serve as Chief Integration Officer, reporting directly to Lane to manage the realization of the $400 million in synergy targets.
