With roots tracing back to the early 1900s, Rockwell Automation is the successor to Rockwell International, which spun off its avionics segment in 2001. It is a pure-play industrial automation company that operates through three segments. Its largest segment by revenue, intelligent devices, sells factory floor-level devices such as motors, drives, sensors, relays, and actuators. Its software and control segment sells visualization, simulation, and human-machine interface software and control products such as programmable controllers, computers, and operator terminals. Its smallest segment, lifecycle services, offers digital consulting, engineered-to-order services, and other outsourced services such as remote monitoring, cybersecurity, and asset and plant maintenance and optimization.

Nucor Corp manufactures steel and steel products. The company's reportable segments are steel mills, steel products, and raw materials. The majority of its revenue is derived from the steel mills segment, which is engaged in producing sheet steel (hot-rolled, cold-rolled, and galvanized), plate steel, structural steel (wide-flange beams, beam blanks, H-piling, and sheet piling), and bar steel products. Nucor manufactures steel principally from scrap steel and scrap steel substitutes using electric arc furnaces (EAFs), along with continuous casting and automated rolling mills. The steel mills segment sells its products mainly to steel service centers, fabricators, and manufacturers located in the United States, Canada, and Mexico.
