About Olin Corporation
Olin Corporation's three business units are Chlor Alkali Products & Vinyls, Epoxy, and Winchester. Winchester manufactures sporting, law-enforcement, and military small-caliber ammunition; it is a supplier of ammunition rather than a maker of complete weapons systems. In September 2026, Winchester announced selection by the U.S. Army as a second-source provider for 5.56mm, 7.62mm, and .50-caliber rifle ammunition. Olin states that it is headquartered in Clayton, Missouri, with offices and manufacturing facilities around the world. Public company materials do not establish a full, current list of military production facilities.

Direct is the company's own reviewed UEIs. Reported by USAspending is subsidiaries as reported by USAspending: recipients that name this company as their parent, not yet reviewed ownership.
Each action counts for the company USAspending reported on that row, so a subsidiary's dollars count for Olin Corporation only for the period it reported Olin Corporation as its parent. Net of de-obligations; these are obligations, not ceilings. They come from the whole USAspending baseline (every recipient size, contracts and assistance) and are a separate view from the curated contract totals on this page. Fiscal year 2027 is partial.
