2. Inventories

Inventories consisted of approximately 39% raw materials and supplies and 61% finished and semi-finished products at July 4, 2026 (approximately 35% and 65%, respectively, at December 31, 2025). Nucor’s manufacturing process consists of a continuous, vertically integrated process from which products are sold to customers at various stages throughout the process. Since most steel products can be classified as either finished or semi-finished products, these two categories of inventory are combined.
