What follows from the reading
Share of working time within reach of AI, on the long-run pace at four in five: 19% now, 27% at the end of 2027, 30% at the end of 2028, 31% at the end of 2030. By the patterns, the work is about 31% desk work, 13% people work and 56% body work. These are the site's industry estimates weighted by the shares below: estimates with a stated method and range, not a forecast of what the company will do. By the same patterns, at the end of 2028 about 67% of the working time stays with people (conversation, in-person and hands-on work), 26% becomes checking a model's work and 6% could be handed over with lighter checks, from the industries' own figures, not the company's roles.
Headcount
14,400 employees as of December 31, 2025 (stated). Not stated as a count; the filing distinguishes U.S.-based teams (retention 89%) from the companywide 83%, so some work abroad.
The filing: “The Steel Dynamics team consisted of approximately 14,400 full-time team members at December 31, 2025.”
The workforce as industry patterns
| Pattern | Share | Reason, from the filing |
|---|---|---|
| Iron and Steel Mills and Ferroalloy Manufacturing | 55% | Steel Operations are 72% of revenue, the electric arc furnace flat roll and long product mills that make the company's steel, read at iron and steel mills by description (c) as the largest part of the workforce; the filing counts no team members by segment. |
| Merchant Wholesalers, Durable Goods (4232, 4233, 4235, 4236, 4237, and 4239 only) | 25% | Metals Recycling Operations (11% of revenue) run the scrap yards that buy, process and sell ferrous and nonferrous scrap, which NAICS counts with recyclable material wholesalers (4239, in 4230A1), read by description (c) since the yards employ many people for their revenue. |
| Fabricated Metal Product Manufacturing (3323 and 3324 only) | 15% | Steel Fabrication Operations (8% of revenue) make joists and deck, which NAICS counts with plate work and fabricated structural products (3323, in 3320A2), read by description (c). |
| Alumina and Aluminum Production and Processing | 5% | Aluminum Operations (2% of revenue), the new flat rolled aluminum mill and its recycled slab centers, are read at aluminum production by description (c) at five percent as the mill staffs up. |
What the filing says about the workforce: 14,400 full-time; annual equity awards to every full-time, non-union, U.S.-based team member; companywide retention about 83%, U.S.-based 89%; profit sharing on consolidated pretax profit; no hourly or union figure stated.
