What OLIN Corp does
In the company’s own words
Olin Corporation (NYSE: OLN) operates as a leading global manufacturer and distributor of chemical products and ammunition. The company maintains its corporate presence at www.olin.com and serves diverse industrial and consumer markets through two primary reportable segments: Chlor Alkali Products and Vinyls, and Winchester.
The Chlor Alkali Products and Vinyls segment produces and sells chlorine, caustic soda, hydrogen, potassium hydroxide, bleach, and vinyl chloride monomer, which serve applications in water treatment, pulp and paper production, pharmaceuticals, and various chemical manufacturing processes. This segment represents the company's core chemical operations and generates the majority of consolidated revenues through both commodity and specialty chemical products.
The Winchester segment manufactures and distributes ammunition and related products for sporting, hunting, and law enforcement applications. Winchester operates as one of the world's largest ammunition manufacturers, maintaining significant market share in the North American ammunition market and serving customers globally.
Olin's business model centers on the production and distribution of essential chemical commodities and ammunition products with established demand across industrial, commercial, and consumer end markets. The company benefits from integrated production facilities, established distribution networks, and long-standing customer relationships developed over decades of operations.
The company operates manufacturing facilities across multiple geographic regions, including North America and international locations, enabling it to serve customers in diverse markets. Olin's competitive advantages include vertically integrated operations in its chemical segment, established brand recognition in ammunition through the Winchester trademark, operational efficiency in commodity chemical production, and diversified end-market exposure that provides revenue stability across economic cycles.
The credit agreement dated March 14, 2025, as amended February 19, 2026, establishes a $1.85 billion credit facility supporting the company's operational and strategic financing needs. This facility reflects Olin's scale as a significant participant in both the global chemical industry and the ammunition manufacturing sector.
