Nucor Corporation (NUE) Business Profile

What it does

Nucor Corporation is a steel and steel-products manufacturer founded in 1955 and headquartered in Charlotte. Leon Topalian is Chair, President and Chief Executive Officer. It makes steel from recycled scrap, principally using electric arc furnaces, then sells that steel and turns it into construction and industrial products.

Its three operating segments are steel mills, steel products and raw materials. Steel mills make sheet, plate, structural and bar steel. Steel products range from joists, decking, tubing, rebar fabrication and metal buildings to insulated panels, warehouse and data-center racking, overhead doors, utility structures and piling. Raw materials operations process and broker scrap, make direct reduced iron, produce natural gas and operate industrial-gas plants.

The company sells primarily to steel service centers, fabricators and manufacturers, while its downstream operations serve construction and infrastructure customers directly or through distribution networks. Nonresidential construction is its largest end-use market. Automotive, appliances, energy, infrastructure, machinery, agriculture, data centers and renewable-energy projects are also end markets.

Nucor is North America’s largest recycler. It recycled approximately 20 million gross tons of scrap steel in 2025. Most operating facilities and customers are in North America, although it also has international trading and sales operations. Management said on the call that Nucor can make or supply roughly 95% of the steel required inside and outside a data center.

How it makes money

Nucor earns revenue by selling tons of steel, finished steel products and raw materials. The steel mills segment is its largest, representing 62% of sales to external customers in 2025. It sells sheet, plate, structural and bar steel, including to customers that use it in automotive, construction, energy, infrastructure and manufacturing applications. Steel products operations use both internally supplied steel and external inputs to make higher-fabrication products for construction and other customers. Raw materials operations supply Nucor’s mills and also sell some scrap, metallics, gases and related services externally.

Sales depend principally on shipment volume and the selling price per ton. Nucor tracks metal margin, the spread between steel selling prices and the cost of scrap and scrap substitutes. Its sheet business has more recurring contracted volume than its other steel businesses: approximately 85% of sheet sales in 2025 were under contracts generally lasting six to 12 months. Those contracts are noncancellable and commonly adjust monthly or quarterly with steel-market indices and/or raw-material costs; remaining sheet volume is sold at prevailing spot prices. Most sales elsewhere are spot-market orders.

Steel mills shipped approximately 19,848,000 tons to external customers in 2025, while 21% of mill shipments went internally to steel products operations. The steel products segment also has project-based work, including fixed-price contracts for joists, deck and fabricated rebar. Its raw-materials segment internally consumed most of the ferrous and non-ferrous metals and scrap substitutes it brokered or processed.

Latest reported totals: 2025 net earnings were $1.74 billion, or $7.52 per diluted share; third-quarter 2026 EBITDA was approximately $2.3 billion and earnings were $5.80 per share.

Customers and how it sells

Most of Nucor’s facilities and customers are in North America. Steel mills sell primarily to steel service centers, fabricators and manufacturers in the United States, Canada and Mexico. The company also uses in-house sales forces, internal distribution companies and trading companies; the latter market products abroad and also buy and sell steel made by Nucor and other producers.

The company has a diversified customer base and was not dependent on a single customer in 2025. Its largest single customer represented approximately 5% of sales. Steel products operations are more closely tied to nonresidential construction, infrastructure and local project delivery. For example, joists and deck are made to customer specifications and generally delivered directly to construction sites on agreed schedules. Metal buildings are sold mainly through independent builder distribution networks, while rebar fabrication operates nearly 70 facilities across the United States and Canada serving local markets.

Construction is the largest end-use market. Other important end markets include automotive, durable goods, capital spending, energy, agricultural equipment, heavy equipment, appliance, data centers and utility infrastructure. Management said on the call that domestic demand was healthy across a range of end markets, while it also described growing data-center business. General Motors is named as a customer for exposed automotive sheet.

Suppliers and costs

Scrap steel is Nucor’s primary steelmaking raw material. It also uses scrap substitutes, including pig iron and direct reduced iron, plus graphite electrodes, alloys, pelletized iron ore, electricity and natural gas. Prices and availability for scrap, energy and consumables can change quickly, and the company may not always be able to pass cost increases through to steel buyers immediately.

Nucor has vertically integrated parts of its supply chain. DJJ processes and brokers scrap and metallics, while two DRI plants supplied approximately 3,300,000 metric tons to its steel mills in 2025. Its natural-gas production is sold to third parties to partly offset exposure to natural gas used by its Louisiana DRI plant and U.S. mills. Universal Industrial Gases can build and operate air-separation units rather than relying entirely on outside long-term service contracts.

Electric arc furnaces give the company the ability to vary production with demand. Its cost base nevertheless includes energy, freight, maintenance, labor, consumables and startup costs. Management said on the call that higher utilization can raise costs for consumables, freight, energy, overtime and services.

Competitive position

Nucor competes in finished steel, unfinished steel and raw-materials markets primarily on price and service. Its steel mills face domestic integrated producers, domestic electric-arc-furnace producers, imports and alternative materials. Concrete, aluminum, plastics, composites and wood can replace steel in some applications. Steel-product businesses compete on price, quality, engineering support, logistics and delivery timing; scrap businesses compete on price and proximity to scrap sources.

Imports are a material competitive factor. Finished carbon and alloy steel imports supplied approximately 18% of U.S. demand in 2025, despite a 17.4% decline from 2024. Management said on the call that finished-steel imports were down more than 13% year over year but reported rising volumes in recent months, including a surge from South Korea. Hyundai is building a sheet mill in Louisiana, and Nippon Steel acquired U.S. Steel. These developments add to domestic sheet-market capacity and competition.

Our reading: Nucor’s recycling, DRI, scrap brokerage and electric-arc-furnace network are a meaningful cost-and-supply moat because they give it several sources of metallic inputs and flexibility to alter production levels as demand changes. [item1; item7]

Our reading: Its downstream product range and North American production footprint are a meaningful service moat in products requiring local fabrication, project sequencing or specialized delivery, but these markets remain price competitive. [item1]

Our reading: Sheet contracts provide some volume visibility, though periodic price resets and spot exposure limit their protection when steel markets weaken. [item1; item7]

Growth opportunities

Nucor’s stated strategy is to grow core steelmaking, expand into related steel products and build on its operating culture. It has invested approximately $9.73 billion over the last three years, with approximately 91% directed to capital expenditures and the remainder to acquisitions. The company has targeted value-added steel, cost structure, operational flexibility and exposure to data centers and renewable energy.

The West Virginia sheet mill is expected to have approximately 3,000,000 tons of annual production capacity and to make 84-inch sheet, including automotive and construction grades. The company expects commercial shipments there to begin ramping in early 2027 after commissioning. It also completed its Lexington rebar micro mill, which has approximately 430,000 tons of expected annual capacity and is in production ramp-up. Management said on the call that Brandenburg shipped approximately 240,000 tons in the third quarter of 2026, roughly one-third of Plate Group shipments.

The steel-products expansion includes data-center racking and infrastructure, insulated panels, doors and utility structures. The company acquired Southwest Data Products to add data-center airflow containment, cabinets, enclosures, caging and installation capabilities. Management said on the call that utilities plan to spend on steel-intensive generation, substation and transmission investment. The company plans for its Utah Towers & Structures facility to reach full production by mid-2027.

Nucor estimates overall steel demand will grow about 2% in 2026. It expects West Virginia utilization and product offerings to build through 2027 and into 2028.

Structural risks

• Global overcapacity and imports. Global steel overcapacity was approximately 704 million net tons in 2025, and excess supply can be exported to the United States at prices that pressure realized steel prices. The effectiveness and future status of tariffs, quotas and duties are uncertain.

• Cyclical end-market demand. Demand is tied to cyclical sectors including construction, energy, service centers, appliances and automotive. Recessions, slow growth or weakness in nonresidential construction can reduce demand while the company continues to carry capital-intensive operations.

• Steel, scrap and energy volatility. Steel pricing, scrap, scrap substitutes, electricity and natural gas are volatile. Nucor may be unable to obtain adequate inputs on acceptable terms or to recover higher input and transportation costs in its selling prices, particularly when prices have already been quoted.

• Large capital-project execution. The business requires substantial maintenance and growth spending. Delays, higher costs, commissioning issues, insufficient funding or lower-than-expected returns from new mills and acquisitions could affect results. The West Virginia sheet mill in particular carries startup and commissioning uncertainty.

• Environmental, power-grid and climate-policy exposure. Steelmaking is energy intensive and produces emissions. Environmental requirements, changes to power grids, carbon-related policy, permitting delays and customer requirements for product transparency can raise costs or affect operations.

• Operational and technology disruptions. Accidents, natural disasters, equipment failures, transportation interruptions, cyberattacks and third-party system failures can interrupt manufacturing, logistics or reporting and can create costs not fully covered by insurance.

Bottom line

Our reading

Our reading: Nucor is a North American steel producer built around electric-arc-furnace steelmaking, scrap recycling and a substantial downstream construction-products business. Its earnings remain exposed to cyclical construction and industrial demand, steel pricing, imports, scrap and energy costs. [item1; item1a; item7]

Our reading: Its raw-materials operations, broad product range, contract sheet business and expanding capacity provide operating flexibility, while the West Virginia ramp and sustained capital-project execution are central variables for the next phase of growth. [item1; item7; call_prepared]
