Deal overview
Olin Corporation and Huntsman Corporation have agreed an all-stock merger of equals to form OlinHuntsman, an integrated North American chemicals company combining Olin's scale and electrochemical feedstock capabilities with Huntsman's downstream formulations and advanced materials. The combined company would have pro forma 2025 revenue of approximately $12.5 billion.
Strategic rationale
The transaction pairs upstream chlorine and caustic production with downstream polyurethane systems, formulations and advanced materials to increase chlorine optionality, improve feedstock conversion into higher-value downstream products and deepen exposure to end markets including automotive, construction and industrial applications. Winchester ammunition will remain a key business within the combined company.

The combined company also expects approximately $125 million of cash tax benefits from acceleration of net operating losses.
