CHARLOTTE, N.C. – January 26, 2026—Nucor Corporation (NYSE: NUE) today announced consolidated net earnings attributable to Nucor stockholders of $378 million, or $1.64 per diluted share, for the fourth quarter of 2025. Excluding impairment charges taken during the quarter, Nucor’s fourth quarter of 2025 adjusted net earnings attributable to Nucor stockholders were $400 million, or $1.73 per diluted share. By comparison, Nucor reported consolidated net earnings attributable to Nucor stockholders of $607 million, or $2.63 per diluted share, for the third quarter of 2025 and $287 million, or $1.22 per diluted share, for the fourth quarter of 2024.

Reflected in the fourth quarter of 2025 losses and impairments of assets are charges of $21 million, or $0.08 per diluted share, related to the closure or repurposing of certain facilities in the steel products segment. Also included in the fourth quarter of 2025 losses and impairments of assets are charges of $6 million, or $0.01 per diluted share, related to the impairment of certain non-current assets in the steel mills segment.

“I want to thank our teammates for their tremendous work throughout 2025—delivering for our customers, advancing key growth projects, and making this Nucor’s safest year,” said Leon Topalian, Nucor’s Chair and Chief Executive Officer. “During the year, we brought several major projects online, including our new rebar micro-mill in Lexington, North Carolina, the Kingman, Arizona melt shop, our Alabama Towers and Structures facility, and our coating complex in Crawfordsville, Indiana. As these and other recently completed projects ramp up, they are beginning to deliver meaningful earnings contributions and we believe they will play an important role in strengthening our earnings power over time.

“Looking ahead to 2026, we are encouraged by robust demand in several key end markets, historically strong backlogs, and federal policies that support a vibrant domestic steel industry. Our focus remains on execution and generating strong, through-cycle returns for our shareholders.”

Nucor Reports Results for the Fourth Quarter of 2025 (Continued)

Analysis of Fourth Quarter of 2025 Results Compared to the Third Quarter of 2025

The steel mills segment earnings decreased in the fourth quarter of 2025 due to lower volumes and margin compression, primarily in sheet. In the steel products segment, earnings declined in the fourth quarter on lower volumes and higher average costs per ton, partially offset by higher average realized pricing. The raw materials segment earnings decreased in the fourth quarter mainly as a result of two scheduled outages at our direct reduced iron facilities that were partially offset by insurance recoveries.

Financial Strength

At the end of the fourth quarter of 2025, Nucor had $2.70 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.

Commitment to Returning Capital to Stockholders

During the fourth quarter of 2025, Nucor repurchased approximately 0.7 million shares of its common stock at an average price of $145.23 per share (approximately 5.4 million shares during the full year 2025 at an average price of $128.66 per share). As of December 31, 2025, Nucor had approximately $406 million remaining authorized and available for repurchases under its share repurchase program. This share repurchase authorization is discretionary and has no scheduled expiration date.

On December 1, 2025, Nucor’s Board of Directors declared a cash dividend of $0.56 per share. This cash dividend is payable on February 11, 2026, to stockholders of record as of December 31, 2025 and is Nucor’s 211th consecutive quarterly cash dividend. Nucor has increased its regular, or base, dividend for 53 consecutive years – every year since it first began paying dividends in 1973.

For the full year of 2025, Nucor returned approximately $1.2 billion to stockholders in the form of share repurchases and dividend payments.

First Quarter of 2026 Outlook Compared to the Fourth Quarter of 2025

We expect earnings to increase in the first quarter of 2026. Earnings in the first quarter of 2026 are expected to increase across all three of our operating segments, with the largest increase in the steel mills segment. In the steel mills segment, the expected increase is due to higher volumes and higher realized prices across all major product categories. In the steel products segment, we expect improved earnings in the first quarter due to increased volumes on stable pricing. The raw materials segment is expected to have increased earnings in the first quarter of 2026.

Earnings Conference Call

An earnings call is scheduled for January 27, 2026 at 10:00 a.m. Eastern Time to review Nucor’s fourth quarter and full year 2025 financial results and provide a business update. The call can be accessed via webcast from the Investor Relations section of Nucor’s website (nucor.com/investors). A presentation with supplemental information to accompany the call has been posted to Nucor’s Investor Relations website.

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. 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 expense (income), 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 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.

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 integrate businesses we acquire; and (15) the impact of any pandemic or public health situation. These and other factors are discussed in Nucor’s regulatory filings with the United States Securities and Exchange Commission, including those in “Item 1A.
