Olin Corporation OLN

Company Overview

Olin Corporation is a U.S.-based manufacturing company operating primarily in the chemicals and ammunition industries. The company is best known as a leading global producer of chlor-alkali products and epoxy materials, as well as a major supplier of commercial and military ammunition. Olin’s operations support a wide range of end markets, including industrial manufacturing, water treatment, construction, consumer goods, defense, and law enforcement.

Olin generates revenue through two core business lines: Chlor Alkali Products and Vinyls and Winchester. The company holds a unique competitive position due to its integrated chemical manufacturing assets, scale in chlor-alkali production, and ownership of the iconic Winchester ammunition brand. Founded in 1892, Olin began as a small explosives manufacturer and evolved through acquisitions and divestitures into a focused chemicals and ammunition company, with a significant transformation following the acquisition of Dow Chemical’s chlor-alkali assets in 2015.
