Nucor and Steel Dynamics Q3 Guidance: What the Miss Signals for Steel Buyers

On September 17, Nucor issued Q3 2026 earnings guidance at $5.55 to $5.65 per diluted share, below analyst consensus of $6.20. Shares fell 3.7% in after-hours trading. Fort Wayne-based Steel Dynamics issued its own Q3 guidance the same day at $5.34 to $5.38, also below consensus, also down more than 3% in after-hours.

Do not read this as a company-specific stumble. Two Midwest EAF producers guiding below consensus on the same day indicates the market had priced in more tariff-driven pricing upside than mills are actually capturing. The pass-through to buyers is real, but the ceiling on further increases may be closer than equity forecasts assumed.

Midwest hot-rolled coil futures are trading near $1,223 per short ton, up from a 52-week low of $793. That is a 35 to 50% increase in under 12 months. Steel prices are rising fast enough to pressure Indiana OEMs and fabricators on input costs. Nucor's steel mills and steel products segments are both expected to post higher Q3 earnings on higher average selling prices, and that pricing flows directly through to your inbound material cost.

Mark October 26 for Nucor's Q3 earnings release. If your steel supply contracts are spot-indexed, assess your margin exposure now, not at year-end.
