What Olin Corporation does

Olin Corporation is a vertically integrated U.S. chemicals and ammunition manufacturer founded in 1892 and headquartered in Clayton, Missouri, with a global workforce of approximately 7,700 employees and 25 manufacturing sites across 8 countries. The company operates through three segments: Chlor Alkali Products & Vinyls (chlorine, caustic soda, bleach, hydrochloric acid, vinyls), Epoxy (resins, systems, curing agents serving coatings, composites, wind energy, electronics, and automotive), and Winchester (small caliber ammunition for military, law enforcement, and commercial sporting markets). It is the #1 chlor-alkali producer in North America, the #1 epoxy resin producer in both North America and EMEA, and the #1 small-caliber ammunition supplier to the U.S. military.

The company's technology backbone is zero-gap membrane cell chlor-alkali production, which materially reduces energy intensity relative to older diaphragm and mercury cell processes. Specialty capabilities include synthetic glycerin production in Stade, Germany (a key pharmaceutical excipient), 100% renewable-energy-powered epoxy manufacturing in Baltringen, Germany, and the Hidrogenii hydrogen liquefaction joint venture with Plug Power in St. Gabriel, Louisiana (15 tons/day capacity). Olin sells primarily through direct enterprise sales teams and B2B contracts across water treatment, chemical processing, PVC, construction, wind energy, defense, and pharmaceutical end markets, with pricing negotiated by quote based on product, grade, volume, and contract duration.

In June 2026, Olin announced an all-stock merger of equals with Huntsman Corporation to form OlinHuntsman Corporation (combined ~$12.5 billion 2025 revenue, Olin shareholders at 54.5%, $400M+ synergies, H1 2027 expected close), which will materially reshape the franchise. Beyond the merger, strategic activity includes the AMMO Inc. small-caliber asset acquisition (January 2025, $55.8M), Braskem EDC supply partnership (November 2025), K2 Pure Solutions bleach distribution expansion (June 2025), and the Hidrogenii hydrogen JV (April 2025). FY2025 revenue was $6.8B with a net loss of $42.8M, reflecting ongoing chlor-alkali cyclical weakness offset by acquisitions and a stable ammunition franchise.
