Nucor — Oct 21, 2024 release

Fourth Quarter of 2024 Outlook We expect consolidated net earnings attributable to Nucor stockholders in the fourth quarter of 2024 to decrease compared to earnings per diluted share of $1.05 reported for the third quarter of 2024. The largest driver for the expected decrease in earnings in the fourth quarter of 2024 is the decreased earnings of the steel mills segment caused by lower average selling prices and decreased volumes. We expect earnings in the steel products segment to decrease in the fourth quarter of 2024 as compared to the third quarter of 2024 due to lower average selling prices and decreased volumes. The earnings of the raw materials segment are expected to increase in the fourth quarter of 2024 as compared to the third quarter of 2024 (excluding the impairment charge taken during the third quarter of 2024).   Page 3 of 10 Nucor Executive Offices: 1915 Rexford Road, Charlotte, North Carolina 28211 Phone 704-366-7000 Fax 704-362-4208 www.nucor.com News Release    Nucor Reports Results for the Third Quarter of 2024 (Continued)   Earnings Conference Call You are invited to listen to the live broadcast of Nucor’s conference call during which management will discuss Nucor’s third quarter results on October 22, 2024, at 10:00 a.m. Eastern Time.
