PART I

Item 1. Business.

Overview

Nucor Corporation, a Delaware corporation incorporated in 1958, and its affiliates (“Nucor,” the “Company,” “we,” “us” or “our”) manufacture steel and steel products. The Company also produces and procures ferrous and non-ferrous materials primarily for use in its steel manufacturing business. Most of the Company’s operating facilities and customers are located in North America. The Company’s operations include international trading and sales companies that buy and sell steel and steel products manufactured by the Company and others.

Nucor is North America’s largest recycler, using scrap steel as the primary raw material in producing steel and steel products. In 2023, we recycled approximately 18.4 million gross tons of scrap steel.

Segments, Principal Products Produced, and Markets and Marketing

Nucor reports its results in three segments: steel mills, steel products and raw materials. The steel mills segment is Nucor’s largest segment, representing 58% of the Company’s sales to external customers in the year ended December 31, 2023.

We market products from the steel mills and steel products segments mainly through in-house sales forces. We also utilize our internal distribution and trading companies to market our products abroad. The markets for these products are largely tied to end-use markets such as nonresidential construction, durable goods and capital spending that are affected by changes in general economic conditions.

We are a leading domestic provider for most of the products we supply, and, in many cases (e.g., structural steel, merchant bar steel, steel joist and deck, pre-engineered metal buildings, steel piling, cold finish bar steel, steel electrical conduit pipe and insulated metal panels), we are the leading supplier.

In recent years we have embarked on a strategy to advance Nucor’s capabilities and further its value creation, as summarized in our Mission Statement: Grow the Core, Expand Beyond and Live Our Culture.

We have examined and prioritized growth opportunities across our core steelmaking, steel products and raw materials operations, and we have identified and executed on several acquisitions and investments to expand the products and services we offer beyond our traditional capabilities. We believe that the Expand Beyond growth opportunities we are pursuing leverage our core competency as a highly efficient, industrial manufacturer working primarily with steel and steel products, while positioning us to generate attractive profit margins and returns on our invested capital selling products into growing end-use markets.

Steel mills segment

In the steel mills segment, Nucor produces sheet steel (hot-rolled, cold-rolled and galvanized), plate steel, structural steel (wide-flange beams, beam blanks, H-piling and sheet piling) and bar steel (blooms, billets, concrete reinforcing bar, merchant bar and engineered special bar quality (“SBQ”)). Nucor manufactures steel principally from scrap steel and scrap steel substitutes using electric arc furnaces (“EAFs”) along with continuous casting and automated rolling mills. The steel mills segment also includes Nucor’s equity method investment in NuMit LLC (“NuMit”) (see “Steel joint ventures”- below), as well as international trading and distribution companies that buy and sell steel manufactured by the Company and other steel producers.

The steel mills segment sells its products primarily to steel service centers, fabricators and manufacturers located throughout the United States, Canada and Mexico. The steel mills segment sold

approximately 18,552,000 tons to outside customers in 2023. In 2023, 80% of the shipments made by our steel mills segment were to external customers. The remaining 20% of the steel mills segment’s shipments went to our steel products segment.

Steel produced by our bar mills has a wide usage serving end markets, including the agricultural, automotive, construction, energy, furniture, machinery, metal building, railroad, recreational equipment, shipbuilding, heavy truck and trailer market segments. Considering Nucor’s production capabilities and the mix of bar products generally produced and marketed, the capacity of the bar mills is estimated at approximately 9,560,000 tons per year.

Reinforcing and merchant bar steel are sold in standard sizes and grades, which allows us to maintain inventory levels of these products to meet our customers’ expected orders. Our SBQ products are hot-rolled to exacting specifications primarily servicing the automotive, energy, agricultural, heavy equipment and transportation sectors.

In April 2022, Nucor announced that it will build a new rebar micro mill, with spooling capabilities, in Lexington, North Carolina. The new micro mill is currently under construction.

In February 2024, Nucor announced that the Board of Directors approved $860 million to construct a rebar micro mill in the Pacific Northwest. Nucor is evaluating potential locations, and the project is expected to take two years to construct, subject to regulatory approvals.

Nucor produces hot-rolled, cold-rolled and galvanized sheet steel to customers’ specifications. Contract sales within the steel mills segment are most notable in our sheet operations, as it is common for contract sales to account for the majority of sheet sales in a given year. We estimate that greater than 80% of our sheet steel sales in 2023 were to contract customers. These sheet sales contracts are noncancellable agreements that generally incorporate monthly or quarterly price adjustments reflecting changes in the current market-based indices and/or raw material cost, and typically have terms ranging from six to 12 months. The balance of our sheet steel sales were made in the spot market at prevailing prices at the time of sale. The number of tons sold to contract customers at any given time depends on a variety of factors, including our consideration of current and future market conditions, our strategy to appropriately balance spot and contract tons in a manner to meet our customers’ requirements while considering the expected profitability, our desire to sustain a diversified customer base, and our end-use customers’ perceptions about future market conditions.

Nucor owns a 51% controlling economic and voting interest in Nucor-JFE Steel Mexico, S. de R.L. de C.V. ("NJSM"). NJSM is a joint venture with JFE Steel Corporation (“JFE”) of Japan that operates a galvanized sheet steel plant in central Mexico with an annual capacity of approximately 400,000 tons, that is expected to supply the country’s automotive market.

In January 2022, Nucor announced it had selected Mason County, West Virginia as the site for its new 3-million-ton state-of-the-art sheet mill. When operational, the new mill will be equipped to produce 84-inch sheet products, and among other features, will include a 76-inch tandem cold mill and two galvanizing lines capable of producing advanced high-end automotive and construction grades.

Nucor also owns a steel beam mill in Berkeley County, South Carolina. Considering Nucor’s production capabilities and the mix of structural products generally produced and marketed, the capacity of the two structural mills is estimated at approximately 3,250,000 tons per year. .

Structural steel products come in standard sizes and grades, which allows us to maintain inventory levels of these products to meet our customers’ expected orders.

Plate steel products come in standard sizes and grades, which allows us to maintain inventory levels of these products to meet our customers’ expected orders.

Steel products segment

In the steel products segment, Nucor produces steel joists and joist girders, steel deck, galvanized torque tubes used in solar arrays, hollow structural section (“HSS”) steel tubing, electrical conduit, fabricated concrete reinforcing steel, cold finished steel, steel fasteners, steel grating and expanded metal, wire and wire mesh, metal building systems, insulated metal panels, steel racking, overhead doors, and utility towers and structures for communications and energy transmission. The steel products segment also includes our piling distributor.

Our capabilities in insulated metal panels, steel racking, overhead doors and towers and structures have all been acquired over the past several years as part of our Expand Beyond strategy, which we believe can enhance our profit margins, return on invested capital and free cash flow generation and, over time, accelerate our overall growth while reducing the volatility of our earnings. A value driver in each of these businesses is to readily leverage our core competencies as a highly efficient manufacturer of steel products, as well as our inclusive, safety-focused, performance-oriented culture.

Except for our overhead doors business, which at present is focused primarily on the garage door repair and replacement market, our steel products businesses primarily serve the nonresidential construction and infrastructure markets.

Sales of steel joists, joist girders and steel decking are dependent on the nonresidential building construction market. The majority of steel joists, joist girders and steel decking are used extensively as part of the roof and floor structural support systems in warehouses, data centers, manufacturing buildings, retail stores, shopping centers, schools, hospitals, and, to a lesser extent, in multi-story buildings and apartments. We make these products to our customers’ specifications and typically deliver them directly to a construction site according to a prearranged schedule and sequence. The majority of these contracts are firm, fixed-price contracts that are, in most cases, competitively bid against other suppliers.

Our Vulcraft/Verco group also manufactures and fabricates steel bar grating products at four of its facilities and serves the new construction and maintenance-related markets. The annual production capacity for our grating business is approximately 49,000 tons.

Reinforcing products are essential to concrete construction. They supply tensile strength, as well as additional compressive strength, and protect concrete from cracking. In many markets, Nucor Rebar Fabrication sells reinforcing products on an installed basis (i.e., Nucor Rebar Fabrication fabricates the reinforcing products for a specific application and performs the installation). Nucor Rebar Fabrication operates nearly 70 fabrication facilities across the United States and Canada, with each facility serving a local market. Total annual rebar fabrication capacity is approximately 1,736,000 tons.

Nucor’s cold finished facilities produce cold finished bars for demanding applications. NCF obtains most of its steel from the Nucor bar mills, ensuring consistent quality and supply through all market conditions. These facilities produce cold-drawn, turned, ground and polished steel bars that are used extensively for shafting and other precision machined applications. NCF produces rounds, hexagons, flats and squares in carbon, alloy and leaded steels. These bars are purchased by the appliance, automotive, construction equipment, electric motor, farm machinery and fluid power industries, as well as by service centers. NCF bars are used in tens of thousands of products. A few examples include anchor bolts, hydraulic cylinders and shafting for air conditioner compressors, ceiling fan motors, garage door openers, electric motors and lawn mowers.

Nucor owns a fully integrated precision castings company, Corporacion POK, S.A. de C.V. (“POK”), with a facility in Guadalajara, Mexico. POK produces complex castings and precision machined products used by the oil and gas, mining and sugar processing industries. POK produces a wide array of precision castings using steel, bronze, iron and specialty alloys. POK complements NCF’s businesses and Nucor’s cold finish facility in Monterrey, Mexico.

Nucor produces mesh at Nucor Steel Connecticut, Inc. and Nucor Wire Products Utah. Nucor also produces mesh in Canada at the Harris Steel Group, Inc. ("Harris") operations of Laurel Steel.

Nucor Fastener’s bolt-making facility in Indiana produces carbon and alloy steel hex head cap screws, hex bolts, structural bolts, nuts and washers, finished hex nuts and custom-engineered fasteners. Nucor fasteners are used in a broad range of markets, including automotive, machine tool, farm implement, construction and military applications.

The sizes of the buildings that can be produced range from less than 1,000 square feet to more than 1,000,000 square feet. Complete metal building packages can be customized and combined with other materials such as glass, wood and masonry to produce cost-effective, energy efficient, aesthetically pleasing buildings designed to the customers’ special requirements. The buildings are sold primarily through independent builder distribution networks in order to provide fast-track, customized solutions for building owners. The primary markets served are commercial, industrial and institutional buildings, including distribution centers, data centers, automobile dealerships, retail centers, schools and manufacturing facilities.

In 2023, Nucor announced it will build two new manufacturing locations to expand NTS adjacent to Nucor's existing steel mills in Decatur, Alabama and Crawfordsville, Indiana.

Raw materials segment

In the raw materials segment, Nucor produces DRI and, through our DJJ subsidiary, brokers ferrous and nonferrous metals, pig iron, HBI and DRI; supplies ferro-alloys; and processes ferrous and nonferrous scrap metal. The raw materials segment also includes our natural gas production operations and our industrial gas business, Universal Industrial Gases. Nucor’s raw materials investments are focused on creating an advantage for its steelmaking operations, through a global information network and a multi-pronged and flexible approach to raw materials supply.

DJJ is the leading broker of ferrous scrap in North America and is a global trader of scrap metal, pig iron and other metallics. In addition to sourcing steel scrap for Nucor’s mills, DJJ is a global trader of ferro-alloys and nonferrous metals. DJJ’s logistics team owns and operates one of the largest independent fleets of railcars in the United States dedicated to the movement of scrap and steel and also offers railcar leasing and railcar fleet management services. These activities have value to Nucor as the leading and most diversified North American steel producer.

Our primary external customers for ferrous scrap are EAF steel mills and foundries that use ferrous scrap as a raw material in their manufacturing process. External customers purchasing nonferrous scrap metal include aluminum can producers, secondary aluminum smelters, steel mills, and other processors and consumers of various nonferrous metals. We market scrap metal products and related services to our external customers through in-house sales forces. In 2023, approximately 8% of the ferrous and nonferrous metals and scrap substitute tons we brokered and processed were sold to external customers. We consumed the balance in our steel mills.

Nucor’s DRI production and brokering capabilities provide our steel mills flexibility to quickly adjust their metallic input mix to changing market conditions, enabling them to maintain competitiveness in the often-volatile ferrous scrap market. With the potential for high-quality scrap to become scarcer, coupled with the risk of third-party supplier disruptions, Nucor’s DRI facilities provide a greater degree of certainty over metallics supply to its steel mills.

Nucor’s access to a long-term, low-cost supply of natural gas is a component in the execution of Nucor’s raw material strategy. Natural gas produced by Nucor’s production operations is sold to third parties to partially offset our exposure to changes in the price of natural gas consumed by our DRI plant in Louisiana and our steel mills in the United States.

Customers and Markets

We have a diverse customer base and are not dependent on any single customer. Our largest single customer in 2023 represented approximately 5% of sales and consistently pays within terms. Our steel mills use a significant portion of the products of the raw materials segment while our steel products segment uses approximately 20% of our steel mills' output.

We believe that nonresidential construction is the largest end-use market that we serve. Products from our steel mills and steel products segments are used in a variety of nonresidential construction applications (e.g., commercial, industrial and infrastructure).

In recent years, we have come to see our EAF-based steelmaking method, with its lower GHG intensity when compared with blast furnace technology that is reliant on mined or extracted virgin iron ore and coking coal, as a competitive advantage for reasons beyond its flexible, highly variable cost base. Customers are expressing greater concern for the GHG emissions in their supply chains and are prioritizing sourcing their steel requirements from EAF-based steelmakers for incorporation into their projects and products.

We have developed branded product lines to leverage this, and other advantages conferred by our specialized capabilities:

We have also invested in people and processes to organize more of our commercial activities around large customers and end-use markets (e.g., automotive, construction, wind energy and solar energy). We have developed dedicated teams tasked with developing relationships and educating decision makers in these sectors.

General Development of Our Business in Recent Years

Consistent with our strategy to Grow the Core, Expand Beyond and Live our Culture, Nucor has invested significant capital in recent years to expand our product portfolio to include more value-added

steel mill products and capabilities, improve our cost structure, enhance our operational flexibility and increase our exposure to markets with attractive growth prospects, such as data centers and renewable energy. These investments totaled approximately $10.92 billion over the last three years, with approximately 54% going to capital expenditures and the remainder going to acquisitions. We believe that these investments will help us deliver higher returns on invested capital and long-term growth. Further, we believe shifting our product mix to a greater proportion of value-added products will make our overall business less volatile.

In our steel mills segment, Nucor has initiated several new capital projects and an acquisition of a majority ownership position of a steel mill to support our expansion of value-added product offerings and cost-reduction strategies.

Nucor Steel West Virginia (“NSWV”) is expected to have an annual production capacity of approximately 3,000,000 tons. The new mill will be equipped to produce 84-inch sheet products, and among other features, will include a 76-inch tandem cold mill and two galvanizing lines. Galvanizing capabilities will include an advanced high-end automotive line with full inspection capabilities as well as a construction-grade line. In addition to its advanced capabilities and strategic location, the new greenfield mill’s product mix is anticipated to have a significantly lower GHG intensity than blast furnace based competitors who have historically supplied the region.

Our acquisition of CSI expanded the reach of Nucor’s sheet mill group to the west coast of the United States and increased our exposure to more value-added sheet steel. CSI’s product capabilities include hot rolled, pickled and oiled, cold rolled and galvanized sheet steels, as well as electric resistance welded pipe. Its annual capacity is approximately 2,000,000 tons.

These mills are referred to as micro mills because they have a smaller operational footprint than our traditional rebar mills, as well as less productive capacity – typically about 400,000 tons per year. This makes them suitable for regional markets and enables us to serve these markets with a logistics cost advantage relative to competitors operating from further away. Micro mills also have a lower environmental footprint due to their smaller size and the fact that their plant design does not typically include a natural gas fired reheat furnace that is common in many steel mills.

Nucor has made strategic acquisitions in the steel products segment over the last three years. These were largely to further the Expand Beyond component of our strategy.

We believe this acquisition has broadened the value-added solutions that the Nucor Buildings group provides to targeted end markets such as warehousing, distribution and data centers. We expect these end-use markets to continue to grow in the coming years and that the use of IMP products within them will also increase. IMPs facilitate cost-effective climate control in the built environment and reduce energy usage and overall operations-related GHG emissions for owners and lessees.

In April 2022, Nucor expanded its steel racking capabilities by acquiring Elite Storage Solutions for $75 million. This acquisition combined with Nucor’s initial steel racking business, Hannibal, form the NWS group.

CHI has approximately 800 teammates across two manufacturing plants in Arthur, Illinois, and Terre Haute, Indiana, and regional warehouses located in California, Colorado, New Hampshire and New Jersey. With a highly diversified national customer network of professional garage door dealers, CHI is able to maintain minimal inventory levels and realize industry-leading fulfillment times, while providing direct delivery to customers.

Capital Allocation Strategy

Our highest capital allocation priority is to invest in our business for profitable long-term growth through our multi-pronged strategy of optimizing existing operations, greenfield expansions and acquisitions.

Our second priority is to return capital to our stockholders through cash dividends and share repurchases. Nucor has paid $1.53 billion in dividends to its stockholders during the past three years. That dividend payout represents 7% of cash flows from operations during that three-year period. The Company repurchased $1.55 billion of its common stock in 2023 ($2.76 billion in 2022 and $3.28 billion in 2021).

We intend to return at least 40% of our net income to stockholders over time via a combination of both cash dividends and share repurchases. Over the past three years, we have returned approximately 48% of our net income in this manner. At December 31, 2023, the Company had approximately $3.32 billion available for share repurchases under the currently authorized share repurchase program.

We intend to execute on our capital allocation strategy while maintaining a strong balance sheet, with relatively low financial leverage, as measured in terms of debt to total capital, as well as ample liquidity. At year-end 2023, our debt to total capital was approximately 24% and we had cash and cash equivalents, short-term investments and restricted cash and cash equivalents on hand of $7.13 billion. At the end of 2023, Nucor had the strongest credit ratings in the North American steel sector (A-/A-/Baa1) with stable outlooks at Standard & Poor’s, Fitch Ratings and Moody’s.

Competition

We compete in a variety of steel and metal markets, including markets for finished steel products, unfinished steel products and raw materials. These markets are highly competitive with many domestic and foreign firms participating, and, as a result of this highly competitive environment, we find that we primarily compete on price and service.

In our steel mills segment, our EAF steel mills face many different forms of competition, including domestic integrated steel producers (who use iron ore converted into liquid form in a blast furnace as their basic raw material instead of scrap steel), other domestic EAF steel mills, steel imports and alternative materials. Large domestic integrated steel producers have the ability to manufacture a variety of products but face significantly higher energy costs and are often burdened with higher capital and fixed operating costs. EAF-based steel producers, such as Nucor, are sensitive to increases in scrap prices but tend to have lower capital and fixed operating costs compared with large integrated steel producers. EAF-based steel producers also typically emit fewer GHGs per ton of steel produced than integrated steel producers.

Global steel production overcapacity continues to be an ongoing risk to Nucor and the entire steel industry. The Organisation for Economic Cooperation and Development ( the “OECD”) estimated that global steel production overcapacity would grow from approximately 556.1 million metric tons in 2022 to approximately 610.8 million tons in 2023, with additional global capacity coming online and economic uncertainty in some parts of the world, particularly China, impacting steel demand. An OECD report states that in Asia, 75 percent of the new capacity coming online between 2024 and 2026 will utilize blast furnace technology. Other regions of the world are not expected to see new blast furnace projects in those years. Adding additional blast furnace capacity will increase carbon emissions. See 'Item 1A. Risk Factors- Industry Specific Risk Factors" for further discussion of overcapacity risks.

China continues to be the largest steel producing country. In 2023, despite much slower economic growth and a continuing downturn in its property market, China still produced more than one billion tons of steel, near its all-time record, accounting for approximately 54% of all steel produced globally.

Circumvention of trade duties also continues to pose a risk. Besides producing over a billion tons of steel in its own country, China is investing heavily in steel production in other countries which is one way it tries to avoid being subject to trade duties on exports to the U.S. market. According to the OECD, Chinese steel companies will account for 65% of cross-border investments or joint venture investments in 2023 or later and will account for more than 80% of the investment in new steelmaking capacity in southeast Asian countries.

The Section 232 steel tariffs enacted in 2018 and successful trade cases have been effective in keeping unfairly traded imports out of the U.S. market. The U.S. government has reached agreements with several allied countries to replace applicable Section 232 tariffs on steel with quota systems or other trade agreements.

The U.S. and European Union are also negotiating the world’s first carbon-based sectoral arrangement, the Global Arrangement on Sustainable Steel and Aluminum, that will restrict access to their markets for higher-emitting steel imports and countries that dump cheap imports. Other countries will be able to join if they meet criteria for restoring market orientation and reducing trade in high-carbon steel and aluminum products. At the end of 2023, the U.S. and EU agreed to extend both the negotiations and existing tariff rate quotas into 2025.

During 2023, sunset review hearings by the U.S. International Trade Commission kept in place antidumping (AD) and countervailing duties (CVD) orders on cut-to-length steel plate from several countries. Trade remedy orders such as these play a key role in allowing the American steel industry to compete on a level playing field against unfairly traded imports, and recent sunset reviews have left the orders almost entirely in place. Sunset reviews are typically held with respect to specific exporters and products every five years.

In December of 2022, the World Trade Organization (WTO) ruled that the Section 232 tariffs violated U.S. WTO commitments. The U.S. government has appealed the ruling. Imports of finished steel in 2023 were down approximately 14% from 2022 levels and finished steel imports accounted for approximately 21% of U.S. market share.

We also experience competition from other materials. Depending on our customers’ end use of our products, there are often other materials, such as concrete, aluminum, plastics, composites and wood that compete with our steel products. When the price of steel relative to other raw materials rises, these alternatives can become more attractive to our customers.

In our steel products segment we manufacture a wide range of products that primarily have construction applications. In each of our product lines, we face competition from well capitalized domestic and international providers offering similar products and services. We compete on price, service (e.g., consulting on engineering requirements, facilitating logistics, and timeliness of order fulfillment) and quality (e.g., reliably producing to exacting custom specifications). We believe we have established a reputation as a market leader who can consistently meet customer needs for these products in a timely manner due to our nationwide footprint of modern production facilities and entrepreneurial, performance driven culture.

Competition in our scrap and raw materials business is also vigorous. The scrap metals market consists of many firms and is highly fragmented. Firms typically compete on price and geographic proximity to the sources of scrap metal.

Backlog

In the steel mills segment, Nucor’s backlog of orders was approximately $3.27 billion and $2.33 billion at December 31, 2023 and 2022, respectively. Order backlog for the steel mills segment includes only orders from external customers and excludes orders from other Nucor businesses. Nucor’s backlog of orders in the steel products segment was approximately $4.97 billion and $6.65 billion at December 31,

2023 and 2022, respectively. The majority of these orders are expected to be filled within one year. Order backlog within our raw materials segment is not meaningful because the vast majority of the raw materials that segment produces are used internally.

Sources and Availability of Raw Materials

An ample supply of high-quality scrap and scrap substitutes is critical to support Nucor’s ability to produce high-quality steel. The goal of Nucor’s raw materials segment is to safely produce, source, trade and transport steelmaking raw materials. Nucor’s raw materials investments are focused on creating an advantage for our steelmaking operations, through a global information network and flexible approach to metallics supply.

Scrap and scrap substitutes are the most significant element in the total cost of steel production. The average cost of scrap and scrap substitutes used in our steel mills segment decreased approximately 14% from $492 per gross ton used in 2022 to $421 per gross ton used in 2023. On average, it takes approximately 1.1 tons of scrap and scrap substitutes to produce one ton of steel. We employ variable steel pricing mechanisms so that we are better able to maintain operating margins and meet our customer commitments as scrap and scrap substitute costs fluctuate.

Nucor remains focused on securing reliable access to low-cost raw material inputs as they are the Company’s largest expense. We believe Nucor’s broad, balanced supply chain is an important strength which allows us to reduce the cost of our steelmaking operations, create a shorter supply chain and have greater control over our metallic inputs. Our investment in DRI production facilities and scrap yards, as well as our access to international raw materials markets, provides Nucor with significant flexibility in optimizing our raw material mix. Additionally, having a significant portion of our raw materials supply under our control minimizes risk associated with the global sourcing of raw materials, particularly since a good deal of scrap substitutes comes from regions of the world that have historically experienced greater political turmoil, such as Ukraine, Russia and Brazil. We believe the continued successful implementation of our raw material strategy, including key investments in DRI production, as well as in the scrap brokerage and processing services performed by our team at DJJ, gives us greater control over our metallic inputs and thus helps us navigate significant fluctuations in the availability and costs of critical inputs.

DJJ acquires ferrous scrap from numerous sources, including manufacturers of products made from steel, industrial plants, scrap dealers, peddlers, auto wreckers and demolition firms. In recent years, we have developed closed loop recycling programs with some of our larger customers, through which we are able to reliably source more high purity prime scrap while reducing the waste inherent in our customers’ operations.

We purchase pig iron as needed primarily from overseas sources. We received over 1,600,000 gross tons of pig iron in 2023. Our DRI plants in Trinidad and Louisiana supplied approximately 3,350,000 metric tons of DRI to our steel mills in 2023. The primary raw material for our DRI facilities is pelletized iron ore, which we purchase from various international suppliers.

The primary raw material for our steel products segment is steel produced by Nucor’s steel mills.

Energy Consumption and Costs

Steel manufacturing is considered an energy-intensive, trade exposed industry. As a result, we continuously strive to make our operations in all three of our business segments more energy efficient. In addition, we proactively engage with suppliers, regulators and other energy industry participants to ensure the continued domestic availability of reliable, low-cost sources of energy in various forms.

Our steelmaking operations utilize EAFs for 100% of their production. The total energy consumed by Nucor includes electricity, natural gas, oxygen and carbon raw material inputs. For the scrap melting

process, electricity is the primary energy source, with natural gas combustion serving as the fuel for reheat furnaces and other pre-heating operations. Our DRI facilities in Trinidad and Louisiana are also large consumers of natural gas.

The availability and prices of electricity and natural gas are influenced by many factors, including changes in supply and demand, the regulatory environment and pipeline/transmission infrastructure.

We use a variety of strategies to manage our exposure to price risk of natural gas, including financial hedges and physical hedges resulting from our owned natural gas drilling operations. In addition to the currently producing wells in the Piceance Basin, Nucor owns leasehold interests in natural gas properties in the South Piceance Basin, in the Western Slope of Colorado. To support Nucor’s operating wells and potential future well developments on these properties, Nucor has entered into long-term agreements directly with third-party gathering and processing service providers. Natural gas produced by Nucor’s drilling operations is sold to partially offset our exposure to changes in the price of natural gas consumed by our DRI plant in Louisiana, and by our steel mills in the United States. Nucor has full discretion on its participation in all future drilling capital investments, however, in the fourth quarter of 2022 we decided that it is unlikely that we will develop the remaining portions of our unproved oil and natural gas properties.

We closely monitor developments in public policy relating to energy production and consumption. We engage with policymakers to provide technical information that can inform policy decisions and avoid unintended adverse consequences of legislative and regulatory actions. We believe that a thoughtful approach to domestic energy policy can help ensure that steel and steel products manufactured in the United States remain competitive in the global marketplace.

Reducing Greenhouse Gas Emissions

While steel is widely understood to be essential in any modern economy, and is increasingly seen as a critical material for addressing challenges associated with climate change, the sector also has received increased attention for its GHG emissions and their potential contribution to climate change.

As the leading U.S. supplier of numerous essential steel products using primarily recycled ferrous scrap metal, we believe we are in a competitively advantageous position. Our circular production process has one third the greenhouse gas emissions intensity of the average traditional extractive steelmaking process using a blast furnace.

We are committed to further reducing our GHG footprint over time. In November 2023, we announced net-zero, science-based greenhouse gas (GHG) targets for 2050 and established a new interim emissions reduction target for 2030. These new GHG intensity targets are defined by the Global Steel Climate Council’s (GSCC) “Steel Climate Standard”, an ambitious standard that is aligned with both the Paris Climate Agreement’s emission reduction goals for the steel sector by 2050, and the International Energy Agency’s “Net Zero by 2050: A Roadmap for the Global Energy System” glidepath.

Nucor’s net-zero 2050 and interim 2030 targets include scopes 1, 2, and 3 emissions from the production of hot rolled steel as defined by the GSCC, making Nucor the first diversified steelmaker in the U.S. to set GHG reduction targets encompassing all three scopes.

We plan to achieve our goals by increasing the use of clean electricity, deploying carbon capture and sequestration where practical and developing near zero GHG ironmaking technologies, as well as through the development and deployment of technologies enabling us to reduce our consumption of injection and charge carbon and natural gas.

Clean Electricity Initiatives

GHG emissions associated with our consumption of electrical power constitute approximately 21% of our current footprint.

We have invested in two companies developing next generation nuclear power technology, and we are exploring ways in which we can work with these companies and with our electric utility partners to accelerate deployment of these technologies on the regional power grids serving our operations, as they mature and become scalable.

Currently, we are a party to two Power Purchase Agreements (“PPAs”). Under these PPAs, we have agreed to purchase for a fixed price output from one solar and one wind project in the United States. The PPAs are structured for monthly financial settlement. We have undertaken these initiatives to support the ongoing transition of the U.S. power grid to a greater reliance on renewable power. As part of these arrangements, we will also receive Renewable Energy Credits (“RECs”) commensurate with the renewable power we purchase. These RECs can be applied against a portion of our GHG emissions, enabling us to receive credit for reducing them. The pay-fixed, receive-floating nature of this arrangement also offsets a portion of our exposure to higher prices for electricity over the life of the contract. We continue to evaluate and consider similar additional transactions, as well as opportunities to deploy renewable power generation and storage assets on site at our facilities.

Carbon Capture and Sequestration (CCS) Activity

In 2023, we signed an agreement with Exxon Mobil to capture, transport, and store carbon from our DRI plant in Convent, Louisiana. ExxonMobil will capture between 600,000 and 800,000 metric tons per year of CO2 from our DRI plant and store the CO2 at an ExxonMobil-owned facility in Louisiana. We expect start-up in 2026. ExxonMobil will receive the related tax credits and pay us a fee for each ton of CO2 we supply.

Near Zero Ironmaking

We have invested in Electra, a company that is working to develop and scale a process to produce carbon-free iron that can be used to make steel. Electra’s technology relies on intermittent, clean energy to refine low-grade iron ores through electrochemical and hydrometallurgical processes. Electra’s process operates at 60°C and removes critical impurities from low-grade ores to produce high purity iron that can be charged directly into EAF steelmaking. Electra’s technology is unproven at scale at this stage.

We have entered into a partnership with Tata Steel to explore the possibility of scaling and commercializing HIsarna, a technology that enables the production of iron from low grade iron ore fines without using coke ovens. Coke ovens consume bituminous coal at high temperature to make coke, an essential ingredient for producing iron in a blast furnace. Both coke ovens and blast furnaces are GHG emissions intensive. While the HIsarna process produces GHG emissions, its CO2 rich waste gas stream can be more readily captured and sequestered. HISarna also produces a slag co-product that has high value for use in the cement industry.

Government Regulations

Our business operations are subject to numerous federal, state and local laws and regulations, the most significant of which are intended to protect our teammates and the environment. Due to the nature of the steel industry, we are subject to substantial regulations related to safety in the workplace. In addition to the requirements of the state and local governments of the communities in which we operate, we must comply with federal health and safety regulations and environmental regulations, the most significant of which are enforced by the Occupational Safety and Health Administration (“OSHA”) and the Environmental Protection Agency ("EPA"). Safety and environmental stewardship are important values to Nucor. We expect that capital expenditures we will direct toward our efforts in these areas will total approximately $280 million in 2024.

Nucor operates a robust and sustainable environmental program that incorporates the concept of each individual teammate, as well as management, being responsible for environmental performance. All steel mills that have been owned and operated by Nucor for over five years are ISO 14001 certified. Achieving ISO 14001 certification requires Nucor’s steel mills to implement an environmental management system with measurable targets and objectives, such as reducing the use of oil and grease and minimizing electricity use.

The principal federal environmental laws that regulate our business include the Clean Air Act (the “CAA”), which regulates air emissions; the Clean Water Act (the “CWA”), which regulates water withdrawals and discharges; the Resource Conservation and Recovery Act (the “RCRA”), which addresses solid and hazardous waste treatment, storage and disposal; and the Comprehensive Environmental Response, Compensation and Liability Act (the “CERCLA”), which governs releases of hazardous substances, and remediation of contaminated sites. Our operations are also subject to state and local environmental laws and regulations.

As it relates to air emission rates, EAFs are the most efficient and cleanest steel making process commercially available today. In comparison to blast furnaces, EAF emissions of sulfur oxides, particulate matter and GHGs per ton of steel are significantly less than integrated steelmaking operations utilizing blast furnaces. Operating EAFs instead of blast furnaces is a proven air quality improvement strategy. In addition, each of our steel mills operates air pollution control devices (baghouses) to collect and capture particulate emissions (“EAF dust”) from the steelmaking process.

The primary raw material of Nucor’s steelmaking operations is scrap metal. The process of recycling scrap metal generates particulate matter emissions that includes contaminants such as paint, zinc, lead, chrome and other metals. Initially, the particulate matter captured and collected is classified as a listed hazardous waste under the RCRA. However, because these contaminants contain valuable metals, the EAF dust is recycled to recover these metals. Nucor sends all but a small fraction of the EAF dust it collects to recycling facilities that recover the zinc, lead, chrome and other valuable metals from this dust.

In addition to recycling EAF dust, Nucor mills beneficially reuse steel slag in road materials as a granular base, embankments, engineered fill, highway shoulders, and hot mix asphalt pavement. The physical, chemical, mechanical and thermal properties of steel slag provide a vital resource for construction companies and activities. We take considerable pride in our recycling efforts.

Not only does the RCRA establish standards for the management of solid and hazardous wastes, the RCRA also addresses the environmental impact of contamination from waste disposal activities and from recycling and storage of most wastes. Periodically, past waste disposal activities that were legal when conducted that may now pose a contamination threat are discovered. When the U.S. Environmental Protection Agency determines these off-site properties are contaminated, Nucor quickly evaluates such claims and, if Nucor is determined to be responsible, we do our part to remediate our share of such issues. Nucor believes all identified liabilities under the RCRA are either currently being resolved or have been fully resolved.

Nucor is also not presently considered a major contributor to any major cleanups under the CERCLA for which Nucor has been named a potentially responsible party. Nucor regularly evaluates these types of potential liabilities and, if appropriate, maintains reserves appropriate to remediate the identified liabilities. Under the RCRA, private citizens may also bring an action against the operator of a regulated facility for potential damages and payment of cleanup costs. Nucor believes that its system of internal evaluation and due diligence provides reasonable assurance as to these types of potential liabilities so that compliance with these regulations will not have a material adverse effect on our results of operations, cash flows or financial condition beyond that already reflected in the reserves established for them.

To protect water resources, the CWA regulates water withdrawals and discharges. When applicable, Nucor maintains water withdrawal and discharge permits at its facilities under the national pollutant discharge elimination system program of the CWA and conducts its operations in compliance with those permits. Nucor also maintains permits from local governments if the facility discharges into publicly owned treatment works.

Capital expenditures at our existing facilities that are associated with environmental regulation compliance for 2023 and 2024 are estimated to be less than $100 million per year.

Human Capital Resources

Culture, Organization and Compensation

We consider our teammates the most important part of Nucor and believe that our culture—and the encouragement that we provide to our teammates to “grow the core; expand beyond; and live our culture” —provides us with a competitive advantage.

While our business strategy shapes "what we do", our culture shapes "how" we go about doing it. We believe adherence to the key tenets of our culture — safety, integrity, trust, innovation, open communication, teamwork, inclusion, courage, can-do attitude and ownership — is a powerful differentiator for Nucor and positions the Company favorably to deliver ongoing stockholder value to our investors.

Nucor has a streamlined organizational structure that allows our teammates to make quick decisions and innovate. Our organization is also highly decentralized, with most day-to-day operating decisions made by our division general managers and their teams. With approximately 32,000 teammates, fewer than 200 work in our principal executive offices in Charlotte, North Carolina. By empowering our teammates, our goal is to foster an entrepreneurial mindset, along with a strong sense of personal responsibility and a culture of accountability and belonging. This empowerment is reinforced by our compensation policies (see discussion on “Pay for Performance” in Our Teammates - Compensation, Training & Development section below) to drive results and contribute to our success.

Teammate input is essential for us to maintain our culture of empowered teammates enabling efficient operational decisions. Aside from our practice of everyday open communication, we periodically ask our teammates to formally provide feedback. Since 1986, we have asked our teammates to complete a comprehensive survey in order to gather feedback on a range of topics, including matters relating to the effectiveness of our culture. We view the survey as an important tool in continually improving our company and ensuring our teammates remain engaged and satisfied. This survey is conducted every three years, the last of which was conducted in 2022. In the most recent survey, 89% of the responses were favorable in the category of “Satisfaction & Commitment.” The overall percentage of negative responses in the most recent survey has dropped by 25 percentage points since the survey began in 1986. The next survey will be conducted in the summer of 2025. Teammates of certain previously acquired businesses – which accounted for approximately 15% of our workforce as of December 31, 2023 – complete a comparable survey that has also shown an improving trend over time.

Safety, Diversity, Equity and Inclusion

One of Nucor’s core values is our teammates’ well-being and safety, and it is our goal to become the safest steel company in the world. Our foremost responsibility is to work safely, which requires our teammates to identify unsafe conditions and activities and mitigate these hazards. We will continue working to eliminate exposures that can lead to injury and encourage our teammates to share their ideas for safety improvement. Two key metrics Nucor uses to measure safety are: the Injury/Illness Rate and Days Away, Restricted and Transfer (“DART”) Case Rate.

Nucor calculates the annual Injury/Illness Rate by dividing the number of work-related injuries and illnesses by the total number of hours worked by all Nucor teammates in a given year, and then multiplying the resulting percentage by 200,000, the equivalent of 100 full-time employees working 40 hours per week, 50 weeks per year. In 2023, we achieved an annual Injury/Illness Rate of 0.79, which marks the fifth consecutive year of a reduced rate. This marks an improvement over our annual Injury/Illness Rate of 0.95 in 2022.

Nucor uses the DART Case Rate to assess and manage the risk of serious injury in the workplace. Nucor calculates the annual DART Case Rate by dividing the number of cases resulting in days away from work, restricted work activity and/or job transfers by the total number of hours worked by all Nucor teammates in a given year, and then multiplying the resulting percentage by 200,000, the equivalent of 100 full-time employees working 40 hours per week, 50 weeks per year. In 2023, we achieved an annual DART Case Rate of 0.36 (0.43 in 2022).

Since 1998, Nucor has used the President’s Safety Award to recognize divisions that achieve strong records of safety performance based on objective metrics. The President’s Safety Award has the following three levels: Platinum, which is awarded to divisions with zero recordable illnesses or injuries; Gold, which is awarded to divisions that have an Illness/Injury Rate below 0.6 and a DART Case Rate below one-third of the national average for their NAICS code; and Silver, which is awarded to divisions that achieve one-third the national average on Illness/Injury Rate and DART Case Rate. In 2023, 31 divisions achieved the Platinum level award, 17 divisions achieved the Gold level award and 24 divisions achieved the Silver level award. Nucor also has 24 OSHA Voluntary Protection Program Sites, OSHA’s highest level of recognition.

In 2020, the Company introduced the Nucor President’s Safety Cup as a way to foster more safety benchmarking throughout the Company. The President’s Safety Cup is an additional annual award that is presented to the region that has the best safety record across all of Nucor. Not only does this reward a facility for exceeding their individual safety goals, but it encourages our teams to innovate and to share ideas and improve safety as a group. The President’s Safety Cup trophy travels among the mills and divisions that make up the winning region.

We believe, however, that safety is about more than just avoiding injuries. At Nucor, safety means making sure our teammates feel safe, welcome and valued when they come to work each day. We are accelerating our diversity, equity and inclusion efforts with the objective of ensuring that each teammate feels a sense of belonging at Nucor. By creating an inclusive workplace, we believe we will attract top talent, foster innovation, increase a sense of empowerment and make Nucor a stronger company. Over the past two years, approximately 31% of Nucor teammates hired or promoted to the Manager or General Manager level were diverse.

Some of the initiatives focused on inclusion, equity and diversity we have launched include:

Our Teammates - Compensation, Training & Development

Nucor had approximately 32,000 teammates as of December 31, 2023. The vast majority of our teammates are located in the United States, with only a small number of teammates located outside of North America. Our operations are highly automated, allowing us to improve safety outcomes and take advantage of lower employment costs while still providing our teammates with compensation that we believe is highly competitive as compared to businesses in our industry. At Nucor, we believe in “Pay-for-Performance.” Nucor teammates typically earn a significant part of their compensation based on their productivity. Production teammates work under group incentives that provide increased earnings for increased production. This additional incentive compensation is paid weekly in most cases. Nucor has also historically contributed 10% of earnings before federal taxes to a profit sharing plan for the majority of teammates below the officer level. We believe such compensation practices incentivize our workforce and reinforce our culture.

While Nucor seeks to hire qualified and talented individuals as new teammates, we also believe in developing the skills of our existing team by providing educational and on-the-job training, in addition to safety training. Further, Nucor believes it is important for senior management to also be familiar with, and have had direct experience running, Nucor’s mills and other operational divisions. The vast majority of our teammates are not represented by labor unions and we believe our teammate turnover is low.

At Nucor, we believe that a diversity of perspectives and background helps to facilitate the “Nucor Way” as we work to “grow the core; expand beyond; and live our culture.” We also believe that recruiting and hiring the best talent available will continue to provide us with the best opportunity for continued future success.

Policies

Nucor has a long history of conducting our businesses in a manner consistent with high standards of social responsibility. We have adopted a comprehensive Human Rights Policy, which operates in conjunction with many other Nucor policies related to ethical conduct and human rights, including our Standards of Business Conduct and Ethics, Code of Ethics for Senior Financial Professionals, Supplier Code of Conduct and Policy on Eliminating Forced Labor from our Supply Chain.

More information about our social strategies, including our most recent Equal Employment Opportunity EEO-1 report, can be found at www.nucor.com/esg.

Item 1A.Risk Factors

Many of the factors that affect our business and operations involve risk and uncertainty. The factors described below are some of the risks that could materially negatively affect our business, financial condition, results of operations and cash flows.

Industry Specific Risk Factors

Overcapacity in the global steel industry could increase the level of steel imports, which may negatively affect our business, results of operations, financial condition and cash flows.

Global steel production overcapacity continues to be an ongoing risk to Nucor and the entire steel industry. The OECD estimated that global steel production overcapacity would grow from approximately 556.1 million metric tons in 2022 to more than 600 million metric tons 2023, with additional capacity expected to come online over the next few years. China continues to be a significant contributor to excess steelmaking capacity, producing more than one billion tons of steel in each of the past four years, despite slower economic growth. China is also investing in new steelmaking capacity in several countries in southeast Asia and Africa.

During periods of global economic weakness, the effects of this overcapacity are amplified because of weaker global demand for steel and steel products. Steel manufacturers in non-market economies tend not to adjust their production levels in line with regional demand and instead export significant amounts of steel and steel products at prices that can be at or below their costs of production. In countries with non-market economies, the steel industry is often subsidized or owned in whole or in part by the government, which can provide these producers with cost advantages or cause their production decisions to be driven by political or social factors rather than price and demand signals. Surplus output from steel producers in these countries can flow into the U.S. market. These imports to the U.S., which are also affected by demand in the U.S. domestic market, international currency conversion rates, and domestic and international government actions, can result in downward pressure on realized steel prices for Nucor, which can materially adversely affect our business, results of operations, financial condition and cash flows.

In March 2018, the Trump Administration imposed a 25% tariff or quota limits on all imported steel products for an indefinite period of time under Section 232 of the Trade Expansion Act. Since then both the Trump and Biden Administrations have negotiated tariff rate quotas with several countries allowing them to export a set amount of steel to the U.S. market without being subject to these Section 232 tariffs. In December of 2022, the World Trade Organization (WTO) ruled that the Section 232 tariffs violated U.S. WTO commitments. The U.S. government strongly disagrees with the ruling and is appealing. When the Section 232 or other import tariffs, quotas or duties expire or if others are further relaxed or repealed, or if relatively higher U.S. steel prices make it attractive for foreign steelmakers to export their steel products to the U.S., despite the presence of import tariffs, quotas or duties, the resurgence of substantial imports of foreign steel could create downward pressure on U.S. steel prices.

Our business requires substantial capital investment and maintenance expenditures, and our capital resources may not be adequate to provide for all of our cash requirements.

Our business requires substantial expenditures for routine maintenance and to remain competitive. For the three-year period ended December 31, 2023, our total capital expenditures were approximately $5.87 billion. We have also recently announced substantial capital projects that we expect will increase production capacity, increase the efficiency of our operations and enhance our product offerings. Although we expect requirements for our business needs, including the funding of capital expenditures, debt service for financings and any contingencies, will be financed by internally generated funds, short-term commercial paper issuances, offerings of our debt securities or from borrowings under our $1.75 billion unsecured revolving credit facility, we cannot guarantee that this will be the case. Additional acquisitions, increases in interest rates or unforeseen events could require financing from additional sources.

Changes in the availability and cost of electricity and natural gas are subject to volatile market conditions that could adversely affect our business.

Our steel mills are large consumers of electricity and natural gas. In addition, our DRI facilities are also large consumers of natural gas. We rely upon third parties for our supply of energy resources consumed in the manufacture of our products. The prices for and availability of electricity and natural gas can be volatile. They are often affected by weather, political, regulatory and economic factors beyond our control, and we may be unable to raise the price of our products to offset increased energy costs. Disruptions, including physical or information systems related issues, that impact the supply of our energy resources could temporarily impair our ability to manufacture our products for our customers. Increases in our energy costs that are not similarly applicable to our competitors' operations could materially adversely affect our business, results of operations, financial condition and cash flows.

Competition from other steel producers, imports or alternative materials may adversely affect our business.

We face ongoing competition from other steel producers and imports that compete with our products on price, quality and service. The markets for our products are highly competitive and a number of firms, domestic and foreign, participate in the steel, steel products and raw materials markets. Depending on a variety of factors, including the cost and availability of raw materials, energy, technology, labor, transportation and capital costs, currency exchange rates, government subsidies of foreign steel producers and other global political and economic factors, our business may be materially adversely affected by more intense competitive forces.

In many applications, steel competes with other materials, such as concrete, aluminum, plastics, composites and wood. Increased use or availability of these materials in substitution for steel products could have a material adverse effect on prices and demand for our steel products.

Our industry is cyclical and both recessions and prolonged periods of slow economic growth could have an adverse effect on our business.

Demand for most of our products is cyclical in nature and sensitive to general economic conditions. Our business supports cyclical industries, such as the construction, energy, metals service centers, appliance and automotive industries. As a result, downturns in the U.S. economy or any of these industries could materially adversely affect our results of operations, financial condition and cash flows. The U.S. economy has experienced a strong recovery from the conditions experienced at the onset of the COVID-19 pandemic, but related labor shortages and supply chain disruptions, new or proposed legislation related to governmental spending, inflation and increases in interest rates have impacted, and will continue to impact, economic growth. Even with this economic recovery, challenges from global production overcapacity in the steel industry and ongoing uncertainties, both in the United States and in other regions of the world, remain.

We are unable to predict the duration of current economic conditions or the magnitude or timing of changes in economic activity. Future economic downturns, prolonged slow growth or stagnation in the economy, a sector-specific slowdown in one of our key end-use markets, such as nonresidential construction, or changes in inflation could materially adversely affect our business, results of operations, financial condition and cash flows, especially in light of the capital-intensive nature of our business.

The results of our operations are sensitive to volatility in steel prices and the cost and availability of raw materials, particularly scrap steel.

We rely to an extent on outside vendors to supply us with key consumables such as graphite electrodes, alloys and other raw materials, including both scrap and scrap substitutes (e.g., prime scrap, pig iron and DRI) that are critical to the manufacture of our steel products. The raw material required to produce DRI is pelletized iron ore. Although we have vertically integrated our business by constructing our DRI facilities in Trinidad and Louisiana and also by acquiring our scrap processing and brokerage operations (“DJJ”) in 2008, we still must purchase most of our primary raw material, steel scrap, from numerous other sources located throughout the United States and internationally. Although we believe that the supply of scrap and scrap substitutes will remain adequate to operate our facilities, prices of these critical raw materials are volatile and are influenced by changes in scrap exports in response to changes in the scrap, scrap substitutes and iron ore demands of our global competitors, as well as volatility in currency rates and political conditions.

At any given time, we may be unable to obtain an adequate supply of these critical raw materials with price and other terms acceptable to us. The availability and prices of raw materials may also be negatively affected by new laws and regulations, allocation by suppliers, interruptions in production, accidents or natural disasters, war and other forms of armed conflict or political instability, changes in exchange rates, worldwide price fluctuations, including due to global political and economic factors, changes in governmental, business and consumer spending, inflation, increases in interest rates, labor shortages, and the availability and cost of transportation. Many countries that export steel into our markets restrict the export of scrap, protecting the supply chain of some foreign competitors. This trade practice creates an artificial competitive advantage for foreign producers that could limit our ability to compete in the U.S. market.

If our suppliers increase the prices of our critical raw materials, we may not have alternative sources of supply. In addition, to the extent that we have quoted prices to our customers and accepted customer orders for our products prior to purchasing necessary raw materials, we may be unable to raise the price of our products to cover all or part of the increased cost of the raw materials or pass along increased transportation costs. Also, if we are unable to obtain adequate, cost-effective and timely deliveries of our required raw materials, we may be unable to timely manufacture sufficient quantities of our products. This could cause us to lose sales, incur additional costs, experience margin compressions or suffer harm to our reputation and customer relationships.

Our steelmaking processes, our DRI processes, and the manufacturing processes of many of our suppliers, customers and competitors are energy intensive and generate carbon dioxide and other GHGs. The regulation of these GHGs could have a material adverse impact on our results of operations, financial condition and cash flows.

Our operations are subject to numerous federal, state and local laws and regulations relating to the protection of the environment, and, accordingly, we make provision in our financial statements for the estimated costs of compliance. There are inherent uncertainties in these estimates. Most notably, the uncertainty of policies, enforcement priorities, legislation and regulations related to climate change mitigation strategies pose the greatest risk.

As a carbon steel producer, Nucor could be increasingly affected both directly and indirectly by new or changing carbon policy decisions and mandates. Carbon is an essential raw material in Nucor’s steel production processes. Furthermore, Nucor steel mills use significant amounts of electricity as all of its mills utilize EAFs for 100% of their steel melting operations and the decarbonization of electricity

generation may lead to high power costs and decreased reliability. Significant changes to the regional power grids serving our steel mills and/or new rulemaking or legislation affecting the operation of these power grids could have a material adverse impact on our results of operations, financial condition and cash flows.

Environmental regulation compliance and remediation could result in substantially increased costs and materially adversely impact our competitive position.

We incur significant costs to achieve and maintain compliance with environmental regulations and remediation obligations. The principal federal environmental laws include the CAA, which regulates air emissions; the CWA which regulates water withdrawals and discharges; the RCRA, which addresses solid and hazardous waste treatment, storage and disposal; and the CERCLA, which governs releases of hazardous substances, and remediation of contaminated sites. Our operations are also subject to state and local environmental laws and regulations.

In addition to the above mentioned statutes, revisions to National Ambient Air Quality Standards, including the implementation actions/decisions of environmental agencies, could make it significantly more difficult to obtain construction permits and permits to expand existing operations. Resulting cancellations, delays or unanticipated costs to these projects could negatively impact our ability to generate expected returns on our investments. These regulations can also increase our cost of energy, primarily electricity, which we use extensively in the steelmaking process. We may in the future incur substantially increased costs complying with such regulations, particularly if federal regulatory agencies were to change their enforcement posture with respect to such regulations.

Emerging customer preferences for greater product transparency and less GHG intensive materials may put us at a competitive disadvantage or reduce demand for our products.

The federal government and numerous states are considering establishing, or have already established, requirements for Environmental Product Declarations (“EPDs”) so that consumers may more readily evaluate the environmental impacts of products. California has enacted the “Buy Clean California Act” and California has also established Global Warming Potential benchmarks through EPDs for certain materials, including certain steel products. EPD legislation has caused Nucor to incur additional costs and has the potential to put Nucor and its customers at a disadvantage to foreign competitors unless standardized mechanisms are used to fully evaluate products produced by foreign producers.

General Risk Factors

We are subject to information technology and cyber-security threats which could have an adverse effect on our business and results of operations.

We utilize various information technology systems to efficiently address business functions ranging from the operation of our production equipment to administrative computation to the storage of data such as intellectual property and proprietary business information. We also utilize third-party service providers for certain information technology services that are important to our operations. We continuously evaluate our cyber-security systems and practices, assess potential threats, and improve our information technology networks, policies and procedures to address potential vulnerabilities. Despite efforts to assure secure and uninterrupted operations, threats from increasingly sophisticated cyber-attacks or system failures could result in materially adverse operational disruptions or security breaches of our systems or those of our third-party service providers. These risks could result in disclosure or destruction of key proprietary information or personal data or reputational damage, theft of assets or trade secrets, or could adversely affect our ability to physically produce or transport steel, resulting in lost revenues, as well as delays in reporting our financial results. We also could be required to spend significant financial and other resources to remedy the damage caused by a cyber-security breach, including to repair or replace networks and information technology systems. We may also contend with potential liability for stolen information, increased cyber-security protection costs, litigation expense and increased insurance premiums.

Our operations are subject to business interruptions and casualty losses.

The steelmaking business is subject to numerous inherent risks, particularly unplanned events such as explosions, fires, other accidents, natural disasters such as floods, hurricanes or earthquakes, critical equipment failures, acts of terrorism, inclement weather and transportation interruptions. Nucor maintains property insurance for these types of losses but self-insures a significant portion of the program. Therefore, while our insurance coverage could offset a portion of the losses relating to some of those types of events, our results of operations and cash flows could be adversely impacted to the extent that any such losses are not covered by our insurance, or that there are significant delays in resolving our claims with our insurance providers.

We acquire businesses and enter into joint ventures from time to time and we may encounter difficulties in integrating businesses we acquire.

We plan to continue to seek attractive opportunities to acquire businesses, enter into joint ventures and make other investments that strengthen Nucor. Realizing the anticipated benefits of acquisitions or other transactions will depend on our ability to operate these businesses and integrate them with our operations, effectively identify and manage risks, and cooperate with our strategic partners. Our business, results of operations, financial condition and cash flows could be materially adversely affected if we are unable to successfully integrate these businesses or otherwise fail to realize the anticipated benefits of acquisitions or other transactions.

Risks associated with operating in international markets could adversely affect our business, financial position and results of operations.

Certain of our businesses and investments are located outside of the United States, in Canada, Mexico and in emerging markets. There are a number of risks inherent in doing business in or sourcing raw materials from such markets. These risks include, but are not limited to: unfavorable political or economic factors; local labor and social issues; changes in regulatory requirements; fluctuations in foreign currency exchange rates, interest rates and inflation; and complex foreign laws, treaties including tax laws, and the Foreign Corrupt Practices Act of 1977. These risks could restrict our ability to operate our international businesses profitably and therefore have a negative impact on our financial position and results of operations. In addition, our reported results of operations and financial position could also be negatively affected by exchange rates when the activities and balances of our foreign operations are translated into U.S. dollars for financial reporting purposes.

Pandemics, epidemics and other public health emergencies in the future, could have a material adverse effect on our business, results of operations, financial condition and cash flows.

Our operations expose us to risks associated with pandemics, epidemics and other public health emergencies. The COVID-19 pandemic had and any future similar events may have negative impacts on our operations, supply chain, transportation networks and customers, which may compress our margins or impact demand for our steel products, including as a result of preventative and precautionary measures that we, other businesses and governments have taken or may take in the future.

In addition, the ability of our teammates and our suppliers’ and customers’ teammates to work may be significantly impacted by these types of public health emergencies. Our customers may be directly impacted by business interruptions or weak market conditions and may not be willing or able to fulfill their contractual obligations. Furthermore, the progression of and global response to these types of public health emergencies, as was the case with the COVID-19 pandemic, can cause and increase the risk of delays in construction activities and equipment deliveries related to our capital projects, including potential delays in obtaining permits from government agencies, as well as changes in the prices and availability of labor and equipment for capital projects.

The accounting treatment of equity method investments, goodwill and other long-lived assets could result in future asset impairments, which would reduce our earnings.

We periodically test our equity method investments, goodwill and other long-lived assets to determine whether their estimated fair value is less than their value recorded on our balance sheet. The results of this testing for potential impairment may be adversely affected by uncertain market conditions for the global steel industry, as well as changes in interest rates, commodity prices and general economic conditions. If we determine that the fair value of any of these assets is less than the value recorded on our balance sheet, and, in the case of equity method investments the decline is other than temporary, we would likely incur a non-cash impairment loss that would negatively impact our results of operations.

Tax increases and changes in tax laws and regulations or exposure to additional tax liabilities could adversely affect our financial results.

The steel industry and our business are sensitive to changes in taxes. As a company based in the United States, Nucor is more exposed to the effects of changes in U.S. tax laws than some of our major competitors. Our provision for income taxes and cash tax liability in the future could be adversely affected by changes in U.S. tax laws.

Nucor recognizes the effect of income tax positions only if those positions are believed to be more likely than not of being sustained. We cannot predict whether taxing authorities will conduct an audit challenging any of our tax positions and there can be no assurance as to the outcome of any challenges. If we are unsuccessful in any of these matters, we may be required to pay taxes for prior periods, interest, fines or penalties.

We are subject to legal proceedings and legal compliance risks.

We spend substantial resources ensuring that we comply with domestic and foreign regulations, contractual obligations and other legal standards. Notwithstanding this, we are subject to a variety of legal proceedings and legal compliance risks in respect of various issues, including regulatory, safety, environmental, employment, transportation, intellectual property, contractual, import/export, international trade and governmental matters that arise in the course of our business and in our industry. For information regarding our current significant legal proceedings, see “Item 3. Legal Proceedings.” A negative outcome in an unusual or significant legal proceeding or compliance investigation could adversely affect our financial condition and results of operations. While we believe that we have adopted appropriate risk management and compliance programs, the nature of our operations means that legal compliance risks will continue to exist and additional legal proceedings and other contingencies, the outcome of which cannot be predicted with certainty, will arise from time to time.

Item 1B.Unresolved Staff Comments

None.

Item 1C. Cybersecurity

Nucor recognizes the importance of developing, implementing, and maintaining effective cybersecurity measures designed to protect our information systems and the confidentiality, integrity, and availability of our data. We face a number of information technology and cybersecurity threats which could have an adverse effect on our business and results of operations.

Notwithstanding the Company’s cybersecurity framework and preventative strategies, we may not be successful in preventing or mitigating a cybersecurity incident that could have a material adverse effect on us. See “Item 1A. Risk Factors” for a discussion of cybersecurity risks.

Risk Management and Strategy

Overview

We have developed and implemented a cybersecurity risk management program that is intended to enable us to assess, identify, and manage risk associated with cybersecurity threats. Our program is based on the Cybersecurity Framework promulgated by the National Institute of Standards and Technology and other applicable industry standards, and includes the following key elements:

The program is designed to foster a culture of cybersecurity risk management across the Company.

Integrated Overall Risk Management

Assessing, identifying, and managing cybersecurity-related risks is integrated into our overall risk management framework. The Company conducts an annual cybersecurity risk assessment and reports the most significant risks and associated planned mitigation strategies to the Audit Committee of the Board of Directors. The annual risk assessment is carried out under the supervision of the President of Nucor Business Technology, the Company’s Cybersecurity Director, and the Company’s Vice President and Corporate Controller. See “Governance” below. The Board also regularly receives focused presentations regarding cybersecurity risks from the Company’s Cybersecurity Director.

Third-Party Engagement

Due to the complexity and ever-changing nature of cybersecurity threats, Nucor engages a range of external experts to assist in its assessment, identification, and management of risks from cybersecurity threats. These include cybersecurity assessors, forensic and incident response experts, and auditors to review the Company’s cybersecurity posture and responsive efforts. Our relationships with these external partners enable us to leverage their expertise with the goal of maintaining best practices.

Oversight of Third-Party Risks

Our third-party service providers, suppliers, and vendors face their own risks from cybersecurity threats that could impact Nucor in certain circumstances. In response, we have implemented processes for overseeing and managing these risks. Those processes include limiting the exposure of our information systems to external systems to the least practicable amount, assessing the third parties’ information security practices before allowing them to access our information systems or data, requiring the third parties to implement appropriate cybersecurity controls in our agreements with them, and conducting ongoing monitoring of their compliance with those requirements. We also utilize third-party risk and compliance monitoring services to monitor our service providers, suppliers, and vendors and to augment the effectiveness of our risk mitigation efforts in this area.

Risks from Cybersecurity Threats

As of the date of this report, no risks from cybersecurity threats, including as a result of cybersecurity incidents we have experienced in the past, have materially affected or are reasonably likely to materially affect the Company, including its business strategy, results of operations, or financial condition.

Governance

The Company seeks to ensure effective governance in managing risks associated with cybersecurity threats, as more thoroughly described below.

Board of Directors Oversight

The Audit Committee of the Board of Directors is responsible for the oversight of risks from cybersecurity threats. The Audit Committee is composed of directors with a wide range of experience, including risk management and controls, and technology. See “Integrated Overall Risk Management” above.

Management’s Role in Cybersecurity Risk Management

A division of the Company known as Nucor Business Technology, or NBT, is responsible for the Company’s information technology needs, including cybersecurity risk assessment and management. NBT’s cybersecurity function is led by the Cybersecurity Director, who reports to the President of NBT, who in turn reports to the Company’s Chair, President, and Chief Executive Officer. The current Cybersecurity Director has twenty years of experience in the cybersecurity field and has broad expertise in cybersecurity threat assessments and detection, mitigation technologies, cybersecurity training, and incident response.

The Company also has a Risk Committee composed of the following members of the Company’s management:

The Risk Committee is responsible for overseeing the Company’s response to cybersecurity incidents. The Risk Committee and the Chair, President, and Chief Executive Officer inform the Audit Committee and the Board of Directors on cybersecurity risks.

Monitoring of Cybersecurity Incidents

The Cybersecurity Director implements and oversees our processes for regularly monitoring our information systems. This includes security measures and regular audits to identify potential issues. In the event of a cybersecurity incident, we have an established incident response plan that requires prompt notification of the Cybersecurity Director or their designee, who in turn oversees our assessment of and response to the incident. The Cybersecurity Director is also responsible for informing the Risk Committee of cybersecurity incidents, which in turn has a detailed process for assessing the impacts of incidents and monitoring the Company’s mitigation and remediation efforts. Depending on the nature of the incident,

this process also provides for escalating notification to senior executives, including the Chair, President, and Chief Executive Officer and to the Board of Directors.

Item 2.Properties

We own most of our principal operating facilities. These facilities, by segment, are as follows:

In the steel products segment, we have 92 operating facilities, excluding the locations listed above, in 39 states with 29 operating facilities in Canada and two in Mexico. Nucor Rebar Fabrication also operates multiple sales offices in Canada and certain other foreign locations. The steel products segment also includes Skyline Steel, LLC, our steel foundation distributor. NWS has leased square footage of approximately 630,000 square feet in Los Angeles, California, and has leased square footage of approximately 420,000 square feet in Houston, Texas.

In the raw materials segment, we have 93 operating facilities in 19 states with one operating facility in Point Lisas, Trinidad. For our DRI facilities in Trinidad and Louisiana, a significant portion of the production process occurs outdoors. The Trinidad site, including leased land, is approximately 1.9 million square feet. The Louisiana site has approximately 174.2 million square feet of owned land with buildings that total approximately 72,500 square feet. DJJ has 85 operating facilities in 18 states along with multiple brokerage offices in the United States and certain other foreign locations.

The average utilization rates of all operating facilities in the steel mills, steel products and raw materials segments in 2023 were approximately 78%, 64% and 71% of production capacity, respectively.

We also own our principal executive offices in Charlotte, North Carolina.

Item 3. Legal Proceedings.

Nucor is from time to time a party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. With respect to all such lawsuits, claims and proceedings, we record reserves when it is probable a liability has been incurred and the amount of loss can be reasonably estimated. We do not believe that any of these proceedings, individually or in the aggregate, would be expected to have a material adverse effect on our results of operations, financial position or cash flows. Nucor maintains liability insurance with self-insurance limits for certain risks.

During 2022, Nucor Steel Louisiana, our DRI facility located in St. James Parish, Louisiana, received allegations of violations of the Clean Air Act from the United States Environmental Protection Agency. A combined settlement is currently being negotiated with the United States Department of Justice, United States Environmental Protection Agency and the Louisiana Department of Environmental Quality. We do not believe that any aggregate settlement for these allegations will be material to Nucor.

There were no other proceedings that were pending or contemplated under federal, state or local environmental laws that the Company reasonably believes may result in monetary sanctions of at least $1.0 million (the threshold chosen by Nucor as permitted by Item 103 of Regulation S-K promulgated under the Securities Exchange Act of 1934, as amended, (the "Exchange Act"), and which Nucor believes is reasonably designed to result in disclosure of any such proceeding that is material to its business or financial condition).

Item 4. Mine Safety Disclosures

Not applicable.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations of Nucor Corporation should be read in conjunction with the consolidated financial statements of the Company and the accompanying notes to the consolidated financial statements.

Management’s Discussion and Analysis of Financial Condition and Results of Operations included in this report discusses our financial condition and results of operations as of and for the years ended December 31, 2023 and 2022. Information concerning the year ended December 31, 2022 and a comparison of the years ended December 31, 2022 and 2021 may be found under “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on February 28, 2023.

Overview

The U.S. economy grew at a faster rate in 2023 – 2.5 percent – compared to 1.9 percent the prior year. Steel market demand in 2023 remained strong across many of the end markets we serve, particularly nonresidential construction. Operating rates at our steel mills for the full year 2023 increased slightly to 78% as compared to 77% for the full year 2022.

Legislation passed by Congress is providing more than $1.5 trillion to rebuild traditional infrastructure, build-out clean energy infrastructure and re-shore semiconductor chip manufacturing back to the United States. These steel-intensive projects are expected to create an estimated 5 to 8 million tons of additional annual steel demand in the coming years. Funding from the Infrastructure Investment & Jobs Act (IIJA) is starting to impact the steel market and that impact is expected to last several years. The CHIPS Act has already generated announcements for dozens of new semiconductor ecosystem projects in the U.S. representing more than $200 billion in private investments. Strong Buy America requirements in the IIJA and the Inflation Reduction Act will promote domestically produced steel being used to rebuild U.S. infrastructure and build-out new clean energy infrastructure. More than half of Nucor products are shipped into the construction market, and Nucor’s lower carbon footprint is expected to provide an additional advantage as states and localities look to rebuild infrastructure in a sustainable manner.

Our Challenges and Risks

Global steel production overcapacity continues to be an ongoing risk to Nucor and the entire steel industry, with the OECD estimating that global steel production overcapacity would grow from approximately 550 million metric tons in 2022 to more than 600 million tons in 2023. However, additional capacity continues to come online and China’s steel production, the largest steel producing country, is still near record levels. In 2023, China’s steel production was more than 1 billion tons for the fourth consecutive year. Circumvention of trade duties also continues to pose a risk, as countries route products through third-party countries to evade duties. Increasingly, China is seeking to evade trade duties by building new steelmaking capacity in other countries with a focus on neighboring countries in southeast Asia, as well as Africa.

An uncertainty we continue to face in our business is the price of our principal raw material, ferrous scrap, which is volatile and often increases or decreases rapidly in response to changes in domestic demand, unanticipated events that affect the flow of scrap into scrap yards, the availability of scrap substitutes, currency fluctuations and changes in foreign demand for scrap. In periods of rapidly increasing raw material prices in the industry, which are often also associated with periods of stronger or rapidly improving steel market conditions, being able to increase our prices for the products we sell quickly enough to offset increases in the prices we pay for ferrous scrap is challenging but critical to maintaining our profitability. We attempt to mitigate the scrap price risk by managing scrap inventory levels at the steel mills to match the anticipated demand over the next several weeks. Certain scrap substitutes, including pig iron, have longer lead times for delivery than scrap, which can make this

inventory management strategy difficult to achieve. Continued successful implementation of our raw material strategy, including key investments in DRI production, coupled with the scrap brokerage and processing services performed by our team at DJJ, give us greater control over our metallic inputs and thus also helps us to mitigate this risk. See "Item 1A. Risk Factors- Industry Specific Risk Factors" for further discussion of raw material risks.

During periods of stronger or rapidly improving steel market conditions, we are more likely to be able to pass through to our customers, relatively quickly, the increased costs of ferrous scrap and scrap substitutes, protecting our gross margins from significant erosion. During periods of weaker or rapidly deteriorating steel market conditions, weak steel demand, low industry utilization rates and the impact of imports create an even more intensified competitive environment and increased pricing pressure. All of those factors, to some degree, impact pricing, which increases the likelihood that Nucor will experience lower gross margins.

Although the majority of our steel sales are to spot market customers in North America who place their orders each month based on their business needs and our pricing competitiveness compared to both domestic and global producers and trading companies, we also sell contract tons, most notably in our sheet operations. Approximately 80% of our sheet sales were to contract customers in 2023 (approximately 85% in 2022), with the balance being sold in the spot market at the prevailing prices at the time of sale. Steel contract sales outside of our sheet operations are not significant. The amount of tons sold to contract customers at any given time depends on the overall market conditions at the time, how the end-use customers see the market moving forward and the strategy that Nucor management believes is appropriate to the upcoming period.

Nucor management considerations include maintaining an appropriate balance of spot and contract tons based on market projections and appropriately supporting our diversified customer base. The percentage of tons that is placed under contract also depends on the overall market dynamics and customer negotiations. In years of strengthening demand, we typically see an increase in the percentage of sheet sales sold under contract as our customers have an expectation that transaction prices will rapidly rise, and available capacity will quickly be sold out. To mitigate this risk, customers prefer to enter into contracts in order to obtain committed volumes of supply from the mills. The vast majority of our contracts include a method of adjusting prices on a periodic basis to reflect changes in the market pricing for steel and/or scrap. Market indices for steel generally trend with scrap pricing changes, but, during periods of steel market weakness, the more intensified competitive steel market environment can cause the sales price indices to decrease resulting in reduced gross margins and profitability. Furthermore, since the selling price adjustments are not immediate, there will always be a timing difference between changes in the prices we pay for raw materials and the adjustments we make to our contract selling prices. Contract sales typically have terms ranging from six to 12 months.

Our Strengths and Opportunities

We are North America’s most diversified steel producer. As a result, our short-term performance is not tied to any one market. We have numerous, large, strategic capital projects at various stages of progress that we believe will help us further diversify our product offerings and expand the markets that we serve. We expect these investments to grow our long-term earnings power by increasing our channels to market, expanding our product portfolio into higher value-added offerings, improving our cost structure and further building upon our market leadership positions.

We believe that Nucor’s raw material supply chain is another important strength. Our investment in DRI production facilities and scrap brokerage and processing businesses provides Nucor with significant flexibility in optimizing our raw materials costs. Additionally, having a portion of our raw materials supply under our control reduces risk associated with the global sourcing of raw materials.

Our highly variable, low-cost structure, combined with our financial strength and liquidity, have allowed us to successfully navigate cyclical steel industry market conditions in the past. In such times, our incentive-based pay system reduces our payroll costs, both hourly and salary, which helps to offset lower

selling prices. Our pay-for-performance system that is closely tied to our levels of production also allows us to keep our highly experienced workforce intact and to continue operating our facilities when some of our competitors with greater fixed costs are forced to shut down some of their facilities. Because we use EAFs to produce our steel, we can easily vary our production levels to match short-term changes in demand.

Evaluating Our Operating Performance

We report our results of operations in three segments: steel mills, steel products and raw materials. Most of the steel we produce in our mills is sold to outside customers (80% in 2023 and 78% in 2022), but a significant percentage is used internally by many of the facilities in our steel products segment (20% in 2023 and 22% in 2022).

We begin measuring our performance by comparing our net sales, both in total and by individual segment, during a reporting period with our net sales in the corresponding period in the prior year. In doing so, we focus on changes in and the reasons for such changes in the two key variables that have the greatest influence on our net sales: average sales price per ton during the period and total tons shipped to outside customers.

We also focus on both dollar and percentage changes in gross margins, which are key drivers of our profitability, and the reasons for such changes. There are many factors from period to period that can affect our gross margins. One consistent area of focus for us is changes in “metal margins,” which is the difference between the selling price of steel and the cost of scrap and scrap substitutes. Increases or decreases in the cost of scrap and scrap substitutes that are not offset by changes in the selling price of steel can quickly compress or expand our margins and reduce or increase our profitability.

Changes in marketing, administrative and other expenses, particularly profit sharing and other variable incentive-based payment costs, can have a material effect on our results of operations for a reporting period as well. These costs vary significantly from period to period as they are based upon changes in our pre-tax earnings and other profitability metrics that are a reflection of our pay-for-performance system that is closely tied to our levels of production.

Evaluating Our Financial Condition

We evaluate our financial condition each reporting period by focusing primarily on the amounts of and reasons for changes in cash provided by operating activities, our current ratio, the turnover rate of our accounts receivable and inventories, the amounts of and reasons for changes in cash used in or provided by investing activities (including projected capital expenditures) and financing activities and our cash and cash equivalents and short-term investments position at period end. We believe that our conservative financial practices have served us well in the past and are serving us well today. As a result, we believe our financial position remains strong.

Comparison of 2023 to 2022

Results of Operations

Nucor reported consolidated net earnings of $4.52 billion, or $18.00 per diluted share, in 2023, which decreased compared to $7.61 billion, or $28.79 per diluted share, in 2022, the latter of which was the most profitable year in the Company’s history. Though decreased from the prior year, 2023 represented the third most profitable year in Nucor’s history.

The primary driver for the decrease in earnings in 2023 as compared to 2022 was the decreased profitability of the steel mills segment. Metal margin in the steel mills segment decreased significantly in 2023 as compared to 2022, as decreases in average selling prices outpaced decreases in scrap and substitute costs. All product groups within the steel mills segment had lower metal margin in 2023 as compared to 2022, with the largest decrease at our sheet mills.

Earnings of the steel products segment decreased in 2023 following a record-setting year for profitability in 2022. Average selling prices and volumes both decreased for the steel products segment in 2023 as compared to 2022. The primary driver for the decreased earnings of the steel products segment in 2023 was the reduced profitability of the joist and deck businesses, both of which had very strong earnings in 2022. Partially offsetting these decreases were increases in profitability at the segment's rebar fabrication, garage doors, insulated metal panels and tubular products businesses in 2023 as compared to 2022. The Company's rebar fabrication business set a new record for profitability in 2023.

Earnings in the raw materials segment decreased in 2023 as compared to 2022 primarily due to decreased earnings at our DRI facilities and scrap processing operations. Included in the earnings of the raw materials segment in 2022 was the $96.0 million write-off of our leasehold interest in unproved oil and gas properties after the Company’s management determined that it was unlikely to develop the leasehold interests in the future.

The following discussion will provide greater quantitative and qualitative analysis of Nucor’s performance in 2023 as compared to 2022.
