Nucor — Key Risks

Global Steel Overcapacity Puts Downward Pressure on Prices

The world produces far more steel than it needs — the OECD estimates global overcapacity at 704 million net tons in 2025, roughly eight times total U.S. annual production. China alone produces over one billion tons per year and exports the surplus at or below cost, which can drag down U.S. steel prices. Tariffs under Section 232 currently help shield domestic producers, but there is no guarantee these protections will remain in place, and their removal could flood the U.S. market with cheap imports.

Raw Material Costs, Especially Scrap Steel, Are Volatile and Hard to Control

Nucor's electric arc furnaces run primarily on recycled scrap steel, a commodity whose price swings with global demand, currency movements, and export policies of other countries. If scrap prices spike right after Nucor has already locked in customer pricing, the company absorbs the margin hit. Some foreign competitors benefit from government-restricted scrap exports in their home countries, giving them a built-in cost advantage.

Energy Costs Can Squeeze Margins Significantly

Steel production is extremely energy-intensive, and Nucor's 100% electric arc furnace (EAF) model makes it especially dependent on electricity. Natural gas is also critical for its direct-reduced iron (DRI) facilities. Since energy prices are set by markets and weather events beyond Nucor's control, a sudden spike in electricity or gas costs — that competitors don't equally face — can meaningfully compress profitability.

The Business Is Deeply Cyclical and Tied to Construction

Demand for Nucor's products moves with the broader economy, particularly nonresidential construction, automotive, and energy sectors. During recessions or prolonged slowdowns, steel demand and prices can fall sharply while the company's fixed costs stay high. Nucor spent roughly $8.90 billion on capital expenditures over the three years ending December 31, 2025, meaning it carries significant ongoing financial commitments regardless of market conditions.

Environmental and Climate Regulations Could Raise Costs

As a carbon steel producer, Nucor faces growing regulatory risk from climate-related rules at the federal, state, and international level. Carbon is a core input in steelmaking, and stricter emissions standards or changes to power grid rules could raise energy costs or force expensive operational changes. California's "Buy Clean California Act" and Environmental Product Declaration (EPD) requirements already add compliance costs and could disadvantage Nucor relative to foreign producers who face less scrutiny.
