Description of the Business
Steel Dynamics, Inc. (SDI), together with its subsidiaries (the company), is one of the largest and most diversified domestic steel producers and metals recycler, combined with a meaningful steel fabrication manufacturing platform. Effective the fourth quarter 2023, the company changed its reportable segments, consistent with how it currently manages the business, representing four reporting segments: steel operations, metals recycling operations, steel fabrication operations, and aluminum operations. Segment information provided within this Form 10-Q, including within Note 7. Segment Information, has been recast for all prior periods consistent with the current reportable segment presentation.
Steel Operations Segment. Steel operations include the company’s electric arc furnace (EAF) steel mills, including Butler Flat Roll Division, Columbus Flat Roll Division, Southwest-Sinton Flat Roll Division, Structural and Rail Division, Engineered Bar Products Division, Roanoke Bar Division, Steel of West Virginia, steel coating and processing operations at The Techs, Heartland Flat Roll Division, United Steel Supply (USS), Vulcan Threaded Products, Inc., warehouse operations in Mexico, and SDI Biocarbon Solutions, LLC, a joint venture to construct and operate a biocarbon production facility.
Metals Recycling Operations Segment. Metals recycling operations include the company’s OmniSource ferrous and nonferrous processing, transportation, marketing, brokerage, and scrap management services primarily throughout the United States and in Central and Northern Mexico.
Steel Fabrication Operations Segment. Steel fabrication operations include the company’s New Millennium Building Systems’ joist and deck plants located throughout the United States, and in Northern Mexico.

Aluminum operations include the recycled aluminum flat rolled products mill being constructed in Columbus, Mississippi, and two satellite recycled aluminum slab centers in Arizona and Mexico.
