Nucor Corporation (NYSE: NUE) announced third quarter 2026 earnings guidance of $5.55 to $5.65 per diluted share. This forecast falls short of the $6.17 analyst estimate.

The guidance represents a substantial increase from the $2.63 per diluted share reported in the third quarter of 2025.

The company reported second quarter 2026 net earnings of $5.04 per diluted share, with adjusted net earnings at $4.84. These second-quarter results included a non-cash, pre-tax benefit of $61 million ($0.20 per diluted share) stemming from the increased valuation of its investment in Helion, a fusion energy company.

Segment Outlook

Third quarter earnings are expected to increase in the steel mills and steel products segments while declining in the raw materials segment.

In the steel mills segment, the expected rise is driven by higher average selling prices and stable volumes. This growth is partially offset by higher costs of products sold. Second-quarter steel mills earnings benefited from $130 million in cash refunds associated with prior periods' raw material procurement costs, a benefit not expected to recur in the third quarter.

The steel products segment is projected to see increased earnings due to higher volumes and higher average realized pricing. Conversely, raw materials segment earnings are expected to decline on lower pricing and shipments.

Corporate and eliminations expenses are expected to be higher in the third quarter. This reflects the absence of the Helion valuation adjustment and intersegment profit eliminations consistent with the prior quarter.

What the Numbers Show

The guidance indicates a strong operational rebound in core steel segments despite cost pressures. While the steel mills segment faces higher product costs and lacks the one-time $130 million refund benefit seen in Q2, the combination of higher selling prices and stable volumes supports significant EPS growth. The divergence between the Q2 adjusted earnings of $4.84 and the Q3 guidance range midpoint of approximately $5.60 suggests that operational improvements in steel mills and products are outweighing the decline in raw materials and the normalization of corporate expenses. However, the miss against the $6.17 estimate highlights elevated market expectations relative to the company's operational outlook.

During the third quarter, Nucor repurchased approximately 2.03 million shares at an average price of $247.04 per share. Year-to-date, the company has returned approximately $1.36 billion to stockholders through share repurchases and dividend payments.
