First Quarter of 2025 Analysis Steel mills segment earnings in the first quarter of 2025 increased from the fourth quarter of 2024, primarily due to increased volumes. Earnings in the steel products segment decreased in the first quarter of 2025 as compared to the fourth quarter of 2024 due to lower average selling prices. Earnings in the raw materials segment decreased in the first quarter of 2025 as compared to the fourth quarter of 2024 due to lower margins at our scrap processing operations and direct reduced iron facilities. Second Quarter of 2025 Outlook We expect earnings in the second quarter of 2025 to increase compared to the first quarter of 2025. Earnings in the second quarter of 2025 are expected to increase across all three of our operating segments, with the largest increase in the steel mills segment. The expected increase in the steel mills segment earnings is primarily due to higher average selling prices at our sheet and plate mills. Earnings in the steel products segment are expected to increase in the second quarter of 2025 as compared to the first quarter of 2025 due to increased volumes. The raw materials segment is expected to have increased earnings in the second quarter of 2025.

Generally, a non-GAAP financial measure is a numerical measure of a company’s performance or financial position that either excludes or includes amounts that are not normally excluded or included in the most directly comparable financial measure calculated and presented in accordance with GAAP. We define EBITDA as net earnings before noncontrolling interests, adding back the following items: interest (income) expense, net; provision for income taxes; losses and impairments of assets; depreciation; and amortization. We define adjusted net earnings attributable to Nucor stockholders as net earnings attributable to Nucor stockholders adding back losses and impairments of assets, net of tax. We define adjusted net earnings per diluted share as net earnings per diluted share adding back the per diluted share impact of losses and impairments of assets, net of tax. Please note that other companies might define their non-GAAP financial measures differently than we do. Management presents the non-GAAP financial measures of EBITDA, adjusted net earnings attributable to Nucor stockholders and adjusted net earnings per diluted share in this news release because it considers them to be important supplemental measures of performance. Management believes that these non-GAAP financial measures provide additional insight for analysts and investors evaluating the Company’s financial and operational performance by providing a consistent basis of comparison across periods.

As such, the forward-looking statements are not guarantees of future performance, and actual results may vary materially from the projected results and expectations discussed in this news release.
