What is the combined annual sales figure expected from the Olin and Huntsman merger, and how does Olin's 2025 sales compare to that total?

The merger of Olin and Huntsman will create a company with about $12.5 billion in annual sales. Olin posted $6.8 billion in sales in 2025, meaning its contribution represents approximately 54% of the combined entity's projected revenue.

What are Olin's three main business segments as described in the news, and what were their respective 2025 sales contributions?

Olin's three main business segments are chlor-alkali (including chlorine, caustic soda, chlorinated organics, and sodium hypochlorite), epoxy, and ammunition (via Winchester). Its chlor-alkali business generated $3.7 billion in sales in 2025; the epoxy unit was acquired in 2015 as part of Dow’s chlorine-chemical business but no standalone 2025 sales figure is given for it; and the Winchester ammunition business brought in $1.7 billion in sales last year.
