Exhibit 99.1 News Release Nucor Reports Results for the First Quarter of 2026 First Quarter of 2026 Highlights • Net earnings attributable to Nucor stockholders of $743 million, or $3.23 per diluted share • Net sales of $9.50 billion • Net earnings before noncontrolling interests of $870 million; EBITDA of $1.51 billion CHARLOTTE, N.C. – April 27, 2026 - Nucor Corporation (NYSE: NUE) today announced consolidated net earnings attributable to Nucor stockholders of $743 million, or $3.23 per diluted share, for the first quarter of 2026. Nucor reported consolidated net earnings attributable to Nucor stockholders in the fourth quarter of 2025 of $378 million, or $1.64 per diluted share (adjusted net earnings of $400 million, or $1.73 per diluted share). Nucor reported net earnings attributable to Nucor stockholders in the first quarter of 2025 of $156 million, or $0.67 per diluted share (adjusted net earnings of $179 million, or $0.77 per diluted share). “Nucor teammates delivered a strong start to 2026, with our steel mills segment achieving a new quarterly shipment record,” said Leon Topalian, Nucor’s Chair and Chief Executive Officer. “All three of our operating segments reported sequential earnings growth, driven by strong demand across key end markets, growing contributions from recent capital investments, and federal trade policies that continue to reduce the flood of unfairly traded imports into the United States. We enter the second quarter with real momentum, committed to executing our growth strategy, generating strong returns for our shareholders, and continuing our pursuit of becoming the safest steel company in the world.” Earnings Before Income Taxes and Noncontrolling Interests by Segment (In millions) Three Months (13 Weeks) Ended April 4, 2026 December 31, 2025 April 5, 2025 Steel mills $ 1,128 $ 516 $ 231 Steel products 285 230 288 Raw materials 45 24 29 Corporate/eliminations (362 ) (269 ) (263 ) $ 1,096 $ 501 $ 285 Analysis of First Quarter of 2026 Results Compared to the Fourth Quarter of 2025 The increase in first quarter earnings was driven primarily by the increase in earnings in the steel mills segment, which experienced higher average selling prices and volumes across all product groups. The steel products segment had improved earnings due to increased volumes and stable average realized pricing. The raw materials segment had higher earnings in the first quarter due to increased average selling prices and volumes. Financial Strength At the end of the first quarter of 2026, Nucor had $2.48 billion in cash and cash equivalents and short-term investments on hand. The Company’s $2.25 billion revolving credit facility remains undrawn and does not expire until March 2030. The Company continues to have the strongest credit ratings in the North American steel sector (A-/A-/A3) with stable outlooks at Standard & Poor’s, Fitch Ratings and Moody’s, respectively.

Second Quarter of 2026 Outlook Compared to the First Quarter of 2026 We expect higher consolidated earnings in the second quarter of 2026, with improved earnings across all three operating segments. In the steel mills segment, the expected increase is due to higher realized selling prices with stable volumes. In the steel products segment, we expect improved earnings due to higher volumes on stable pricing. The raw materials segment is expected to have increased earnings due to higher realized pricing.

Non-GAAP Financial Measures The Company uses certain non-GAAP (Generally Accepted Accounting Principles) financial measures in this news release, including EBITDA, adjusted net earnings attributable to Nucor stockholders and adjusted net earnings per diluted share.

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 and noncontrolling interests. 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 and noncontrolling interests. 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.

The words “anticipate,” “believe,” “expect,” “intend,” “project,” “may,” “will,” “should,” “could” and similar expressions are intended to identify those forward-looking statements. These forward-looking statements reflect the Company’s best judgment based on current information, and, although we base these statements on circumstances that we believe to be reasonable when made, there can be no assurance that future events will not affect the accuracy of such forward-looking information. 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. Factors that might cause the Company’s actual results to differ materially from those anticipated in forward-looking statements include, but are not limited to: (1) competitive pressure on sales and pricing, including pressure from imports and substitute materials; (2) U.S. and foreign trade policies affecting steel imports or exports; (3) the sensitivity of the results of our operations to general market conditions, and in particular, prevailing market steel prices and changes in the supply and cost of raw materials, including pig iron, iron ore and scrap steel; (4) the availability and cost of electricity and natural gas, which could negatively affect our cost of steel production or result in a delay or cancellation of existing or future drilling within our natural gas drilling programs; (5) critical equipment failures and business interruptions; (6) market demand for steel products, which, in the case of many of our products, is driven by the level of nonresidential construction activity in the United States; (7) impairment in the recorded value of inventory, equity investments, fixed assets, goodwill or other long-lived assets; (8) uncertainties and volatility surrounding the global economy, including excess world capacity for steel production, inflation and interest rate changes; (9) fluctuations in currency conversion rates; (10) significant changes in laws or government regulations affecting environmental compliance, including legislation and regulations that result in greater regulation of greenhouse gas emissions that could increase our energy costs, capital expenditures and operating costs or cause one or more of our permits to be revoked or make it more difficult to obtain permit modifications; (11) the cyclical nature of the steel industry; (12) capital investments and their impact on our performance; (13) our safety performance; (14) our ability to 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 Nucor Reports Results for the First Quarter of 2026 (Continued) integrate businesses we acquire; and (15) the impact of any pandemic or public health situation.
