• Nylon Solutions: This segment includes the production and sale of Nylon 6 resin, primarily under the Aegis® brand name, and caprolactam. Nylon 6 resin is used in various applications such as carpets, automotive and electric components, sports apparel, food packaging, and other industrial applications. Caprolactam is the key monomer used in the production of Nylon 6 resin and is also sold to customers for the manufacture of polymer resins to produce fibers, compounds, and other nylon products. The Hopewell manufacturing facility is one of the world's largest single-site producers of caprolactam.

• Plant Nutrients: This segment focuses on the production and sale of ammonium sulfate, a fertilizer containing nitrogen and sulfur, two key plant nutrients. The ammonium sulfate is derived from the integrated operations at the Hopewell manufacturing facility, making AdvanSix the world's largest single-site producer of ammonium sulfate fertilizer. The company also manufactures sulfuric acid, ammonia, and carbon dioxide as part of its integrated operations and sells any excess material not consumed internally. The ammonium sulfate is sold under the brand name Sulf-N®.

• Chemical Intermediates: This segment involves the manufacture, marketing, and sale of a range of chemical intermediate products, including acetone, phenol, AMS, cyclohexanone, oximes, cyclohexanol, alkyl-amines, and specialty amines. These intermediates are used in various end-products such as solvents, paints, coatings, adhesives, resins, herbicides, automotive components, and water treatment and pharmaceutical intermediates. The phenol produced at the Frankford plant is a key chemical intermediate used in the caprolactam manufacturing process, with any remaining phenol sold to customers for use in phenolic resins, alkyl phenols, and Bisphenol A used for epoxy resins and polycarbonate. All acetone produced is sold to customers for use in products such as methyl methacrylate, polycarbonate, epoxy resins, ketones, and solvents used widely in automotive and construction, as well as agrochemicals.

AdvanSix holds a strong position within the industry, benefiting from its vertically integrated manufacturing facilities, scale, access to lower-cost raw materials, and high plant utilization rates. These advantages help the company maintain its position as the world's lowest-cost producer of caprolactam. The company's integration allows it to remain flexible while optimizing sales from its diverse portfolio of products. Additionally, the location of its manufacturing operations in the United States provides access to low-cost natural gas, a key raw material needed for the production of ammonia used in the production of caprolactam and ammonium sulfate, as well as the source of energy for its manufacturing operations. AdvanSix competes with integrated manufacturers such as BASF Corporation, UBE Corporation, DOMO Chemicals GmbH, Envalior, Highsun Group Holdings Ltd., and Sinopec Limited in the Nylon Solutions segment. For Plant Nutrients, the company competes with caprolactam/ammonium sulfate co-product manufacturers and direct ammonium sulfate producers such as Pasadena Commodities International and Nutrien Ltd. In the Chemical Intermediates segment, AdvanSix competes with stand-alone phenol and acetone producers, such as INEOS Phenol and Altivia, and, with respect to its amines product line, its key alkyl amines U.S.-based competitor is Eastman Chemical Company.
