ITEM 1. BUSINESS

Steel Dynamics, Inc. is one of the largest domestic steel producers and metal recyclers in the United States, based on estimated steelmaking and steel coating capacity of approximately 16 million tons and actual metals recycling volumes as of December 31, 2024, with one of the most diversified product and end market portfolios in the domestic steel industry, combined with meaningful downstream steel fabrication operations. The company is currently investing in its aluminum operations to further diversify its end markets with plans to supply aluminum flat rolled products with high recycled content to the countercyclical sustainable beverage can industry, in addition to the automotive and industrial sectors. Primary sources of revenue are currently from the manufacture and sale of steel products, the processing and sale of recycled ferrous and nonferrous metals, and the fabrication and sale of steel joists and deck products.

We refer to our founding principles as our six core strategic pillars. They bring us together with a common focus, and they provide the foundation upon which we operate and grow. Our unique entrepreneurial culture and business model benefit us operationally, financially, and through the responsible use of our resources in diverse economic environments. Innovation in all forms is essential to our success, and our teams focus on how to do things “smarter” within our current operations, as well as how we continue to grow. This means creating solutions for our teammates, customers, suppliers, and other stakeholders. It also includes finding ways to “do business” with fewer resources and less environmental impact. Our six strategic pillars and the team’s execution of them each day has driven our success and sustainability.

●

Health & Safety – Safety is our primary focus and core value. Nothing surpasses the importance of creating and maintaining a safe work environment. Our goal is zero injuries—no accidents.

●

Entrepreneurial Culture – Fosters a team of energetic, positive, driven, innovative and diverse individuals by utilizing open communication and meaningful performance-based compensation aligned to our strategic focus.

●

Customer Commitment – We focus on being a preferred partner of our customers by providing quality products and unique supply chain solutions to meet their current and future needs.

●

Strategic Sustainable Growth – We focus on strategic growth with intentional margin expansion and consistency through-the-cycle.

●

Innovation – Through individual creativity and ingenuity, our teams drive innovation to improve safety, quality, productivity, and resource sustainability. We strive to provide unique, superior products, customer supply chain solutions, and next-generation technologies and processes.

●

Financial Strength – Through our adaptable value-added product diversification, vertically connected businesses model, coupled with our highly variable operating cost structure and performance-based incentive compensation, along with our continued operating innovations and efficiency, we achieve higher utilization and lower costs, which provide strong cash flow generation through both strong and weak market cycles.

Differentiated Model - Uniquely Steel Dynamics

Competitively advantaged differentiation in everything we do is core to our long-term value creation strategy. We distinguish ourselves in every aspect of our business through an overarching spirit of excellence.

Table of Contents

Unique Entrepreneurial Culture

Our entrepreneurial culture is the foundation of our success and is driven by our extensive, performance-based incentive compensation philosophy for those on the plant floor to our senior leadership team. Over 60% of a production team member’s total potential compensation is “at risk” to both quality production and cost-effectiveness metrics. Over 85% of our senior leadership team’s total potential compensation is “at risk” to companywide financial performance metrics that encourage long-term value creation, including return on equity, growth, cash generation, and return on invested capital measures. We believe diversity within our teams enhances broad-based thinking, innovation, and value creation. Our common goal of consistently achieving excellence in all we do is reflected in the esprit de corps that permeates our team.

Diversified, Value-Added Product Offerings and Supply-Chain Solutions

We have one of the most diversified, high-margin product offerings within the domestic steel industry. We have a track record of profitable growth, driving diversification in both end markets and value-added product offerings to sustain higher volume and profitability through varying market environments. Over 70% of our steel and steel fabrication sales are considered value-added. Throughout our history and today, we seek to provide unique supply-chain alternatives for our customers to increase efficiency, reduce time and costs, and promote decarbonization opportunities. Growing with our customers in this manner has proven to be invaluable in creating long-lasting relationships and product development.

The majority of our steelmaking operations are in locations near sustainable sources of scrap metals and near our customer base, allowing us to realize freight savings for inbound scrap as well as for outbound steel products destined for our customers. This also allows us to provide consistent on-time delivery to our customer base with relatively short lead times, further solidifying our customer relationships.

This diversified portfolio of products enables us to access a broad range of markets, serve a large customer base, and helps mitigate our market exposure to any one product or sector, resulting in increased through-cycle steel mill utilization. In addition, our value-added product offerings help to balance our exposure to commodity grade products supplied by other manufacturers. We will continue to seek additional opportunities, such as entering the recycled aluminum flat rolled products market, and collaborating with our customers to anticipate their future needs by further expanding our range of products and offerings. In 2024, we began operations on our four new value-added flat roll steel coating lines comprised of an additional paint line and galvanizing line located onsite at our Southwest-Sinton Flat Roll Division and a paint line and galvanizing line at our Heartland Flat Roll Division. As with all our growth initiatives, we seek to competitively differentiate ourselves through service, product capability and quality, and supply-chain solutions.

Vertically Connected Businesses and Pull-Through Volume Advantage

Our vertically connected businesses contribute to our higher through-cycle steel production and overall profitability. Our internal manufacturing businesses are a significant competitive advantage supporting higher and more stable through-cycle earnings and cash flow generation. Our steel fabrication operations and downstream processing locations use a significant amount of steel in their operations. During weaker steel demand environments, we can source their steel needs internally, and during strong steel demand environments, we have the option to also purchase their steel needs externally. Ultimately, we optimize our companywide profitability and minimize earnings volatility. In 2024, our own steel consuming businesses purchased 1.7 million tons of steel from our steel mills, representing 14% of our total 2024 steel shipments.

A strategic and synergistic relationship also exists between our electric arc furnace (EAF) steel mills and metals recycling operations. Our metals recycling platform is the largest supplier of recycled ferrous scrap to our steel operations and is expected to be the largest supplier of recycled aluminum scrap to our aluminum operations. This allows us to reduce companywide working capital, as lower scrap inventory volume is required at our steel mills. We are also able to source higher-quality scrap for our steel mills, increasing availability, optimizing costs, and improving quality.

Technologically Advanced, Low-Cost, Highly Efficient Operations

We operate some of the most technologically advanced and environmentally responsible steel mills in the world. Our steel mills generate a fraction of the greenhouse gas (GHG) emissions per ton of steel produced as compared to traditional blast furnace steel production and the average global steel industry. Our value-added product diversification, circular manufacturing model, and performance-based incentive compensation programs support our efficient, environmentally responsible, and competitively advantaged footprint. Coupled with our low, highly variable cost structure and our continued operating innovation and efficiency, we are one of the most profitable and lowest-cost domestic steel producers.

Transformational Growth / New Recycled Aluminum Flat Rolled Strategic Investments

We are nearing the completion of our lower-carbon-emitting, recycled aluminum flat rolled products mill. Our investment includes a 650,000-metric ton recycled aluminum flat rolled products mill in Columbus, Mississippi, and two supporting satellite recycled aluminum slab centers. We are bringing our culture and related operating efficiencies to the flat rolled aluminum industry. This investment will allow us to broaden our ability to serve our existing customers as well as new customers by adding high-quality, lower-carbon flat rolled aluminum to our product portfolio. A significant number of our existing carbon flat rolled steel customers also consume, or process aluminum flat rolled products for automotive, appliance, construction, and other applications. We are developing our property to allow customers to locate on-site, with one customer already committed to co-locating and others expected to co-locate at the rolling mill site in Columbus, enhancing cost efficiencies and reducing emissions across the supply chain. The product mix from the flat rolled products mill is expected to be approximately 45% sustainable beverage packaging, 35% automotive, and 20% common alloy and industrial use. The state-of-the-art recycled aluminum flat rolled products mill will utilize a significant amount of aluminum scrap, and as such is also a complementary extension of the company’s metals recycling platform. The product offering will be supported by various value-added finishing lines, including two CASH (continuous annealing solutions heat treating) lines, a coating line, and downstream processing and packaging lines. We plan to begin shipments mid-year 2025. Our unique performance-based operating culture, coupled with our experience in successfully constructing and operating cost-effective, highly profitable flat roll steel mills and coating lines, positions us exceptionally well to execute this significant strategic investment.

Sustainability

Our commitment to all aspects of sustainability is embedded in our founding principles – valuing our people, our partners, our communities, and our environment. These strategic principles drive long-term value creation for all of us. We are committed to operating our business in an environmentally responsible manner and have been since our founding. Our steel mills exclusively use EAF technology, which uses recycled ferrous scrap as the primary raw material, producing lower-carbon emission quality steel products for our customers and driving returns for our shareholders. Our sustainability and decarbonization strategy is an ongoing journey, and we plan to use our entrepreneurial, innovative spirit to continue to be a leader in the industry.

We intentionally developed a circular manufacturing model. Our metals recycling platform collects and processes scrap, which is then sold to end users for reuse, including our EAF steel mills and our aluminum operations. Our products are then sold to consumers that both further process and manufacture end products. We sell a meaningful amount of steel to our own manufacturing businesses that in turn sell finished products to consumers. Scrap, from the industrial manufacturing process, and from when these products ultimately reach the end of their lives, can be collected and used again in our steel and aluminum operations, creating our circular manufacturing model.

While we believe we operate some of the most efficient steel operations in the world, we recognize the need for continuous improvement. In 2023, we began construction of a biocarbon production facility located in Columbus, Mississippi. The facility will use high-temperature pyrolysis to convert sustainably sourced biomass to high-purity biocarbon. We will use this biocarbon as a renewable replacement for anthracite in our steelmaking operations, which could result in as much as a 35% reduction in our steel mills’ Scope 1 GHG absolute emissions. The facility is projected to begin operations in the first half of 2025. This investment represents a significant step toward the decarbonization of our steel mills.

We believe in empowering our teams and rewarding them for their achievements through a four-tiered, performance-based compensation framework. The various components of our compensation programs promote a balance of high-return growth, effective capital investment, low-cost operations, and risk mitigation. By rewarding our teams based on their performance as an individual, as a team, as a company, and based on shareholder interests, we believe we have the ultimate alignment with our external constituents.

Table of Contents

This is achieved through the following methods:

●

Individual performance awards consist of an individual’s base compensation, which is determined by their individual superior performance, responsibilities, and skill level.

●

Team performance awards, such as quality production, return on assets, and conversion bonuses, are based on departmental results, focusing on productivity, cost control, and efficient use of assets.

●

Companywide performance awards unite everyone through our profit-sharing program, which is based on consolidated pretax profitability, and our 401(k) match, which is based on consolidated return on assets.

●

Alignment with our shareholders and the pursuit of long-term value creation is fostered through the issuance of restricted stock units. Each full-time, non-union, United States-based team member receives annual equity awards. These awards generally have a two-year vesting period, supporting retention and companywide strategy alignment.

Our team-based culture and competitive pay structure support continued high retention. In 2024, our companywide team retention was approximately 79%, with U.S.-based teams retention of 89%. Our compensation framework helps ensure that we remain strong with best-in-class performance and retain top talent even in economic downturns. We all share in the company’s successes, as well as the challenges.

Talent Development and Educational Opportunities

Our people represent the foundation of our six strategic pillars. Their continued education and talent development are paramount to our success. Our educational assistance and development programs encourage personal growth so individuals can remain current in their areas of responsibility, as well as develop new skills for advancement. Senior leadership plays a key role in our development programs, linking our culture to critical, proven leadership concepts. As we continue to grow, building talent, retaining team members with relevant industry and technical experience, and creating opportunities within our teams are some of our most important tasks and are critical to our long-term success.

Workplace Philosophy

Our people are the foundation of our success and are our most important resource. Our culture safeguards all people and requires each person to be treated fairly and with dignity. We have equal employment opportunity, and all job-related considerations are based on merit and ability. We do not tolerate harassment or disrespect of any kind. We respect human rights, which includes providing safe work environments for our people, providing fair compensation based on job responsibilities and performance, and ensuring all team members meet minimum age requirements and eligible working status to qualify for employment. Our leadership receives recurring training on these critical topics.

We recognize the value of having a business that reflects a variety of backgrounds and experiences. We work together as a unified team and respect each other as individuals. Our team-based compensation structure reinforces this philosophy. We strive to create a welcoming and open environment, ensuring the best ideas are heard and valued regardless of the position or the individual. We believe these ideals will continue to drive our success. Our team member population is representative of our industry and the communities where we live and work.

Steel Operations Segment

Steel operations consist of our EAF steel mills, producing steel from ferrous scrap and scrap substitutes, utilizing continuous casting and automated rolling mills, and numerous steel coating, processing lines and warehouse operations. Our steel operations sell directly to end-users, steel processors, steel fabricators, and service centers. These products are used in numerous industry sectors, including the construction, automotive, manufacturing, transportation, heavy and agriculture equipment, energy, and pipe and tube (including OCTG) markets. Our steel operations accounted for 69%, 67%, and 65% of our consolidated net sales during 2024, 2023, and 2022, respectively. We are predominantly a domestic steel company. Export sales represented 6%, 8%, and 5% of our steel segment net sales during 2024, 2023, and 2022, respectively.

Our steel operations consist primarily of steelmaking and numerous coating operations. In 2024, we had approximately 9.4 million tons of flat roll steel annual production capacity. We have an additional 2.0 million tons of flat roll steel processing capacity through The Techs and our Heartland Flat Roll Division, as well as distribution of metallic coated and pre-painted products through United Steel Supply (USS). We have annual flat roll galvanizing capability of 5.5 million tons and painting capability of 2.0 million tons. We also have approximately 4.6 million tons of long product steel capacity at our long products divisions.

Capacities represent maximum estimated manufacturing capabilities based on steel mill configuration and related team member support. These capacities do not represent expected volumes in a given year. In addition, estimates of steel mill capacity are highly dependent on the specific product mix manufactured. Each of our steel mills can and do roll many different types and sizes of products; therefore, our capacity estimates assume a typical product mix.

The following chart summarizes the types of sheet steel products sold by sales dollars, during the respective years, with cold rolled and coated products representing value-added products:

Customers. Steel processors and service centers typically act as intermediaries between primary sheet steel producers and the many end-user manufacturers that require further processing of hot roll coils. The additional processing performed by the intermediate steel processors and service centers include pickling, galvanizing, cutting to length, slitting to size, leveling, blanking, shape correcting, edge rolling, shearing, and stamping. We believe that our intermediate steel processor and service center customers will remain an integral part of our customer base. The Columbus and Sinton Flat Roll Divisions allow us to capitalize on the industrial markets in the Southern United States and Mexico, as well as further expand our customer base in painted, line pipe, and other pipe products. Galvanized flat rolled products produced by our Butler, Columbus, and Sinton Flat Roll Divisions are similar and are sold to a similar customer base. The Techs and Heartland Flat Roll Division specialize in the galvanizing of specific types of flat roll steels in primarily non-automotive applications, servicing a variety of customers in the heating, ventilation and air conditioning (HVAC), construction, agriculture, and consumer goods markets. USS adds a complementary distribution channel for metallic coated and pre-painted flat roll steel coils to the roll-former market, serving the roofing and siding industry. This connects us to an industry sector with customers that have not historically purchased steel directly from a steel producer. Our sheet steel operations also provide a substantial portion (64% in 2024) of the sheet steel utilized in our steel fabrication operations.

Steel Operations Segment Competition

The markets in which we conduct business are highly competitive with an abundance of competition in the carbon steel industry from North American and foreign integrated and mini-mill steelmaking and processing operations. We compete in numerous industry sections, most significantly tied to the construction, automotive, and other manufacturing sectors. In many applications within these industry sections, steel competes with other materials, such as aluminum, cement, composites, plastics, carbon fiber, glass, and wood. Some of our products are commodities, subject to their own cyclical fluctuations in supply and demand. However, we are focused on providing a broad range of diversified value-added products that de-emphasize commodity steel. The primary competitive influences on products we sell are price, quality, and value-added services.

Metals Recycling Operations Segment

Metals Recycling operations include both ferrous and nonferrous scrap metal processing, transportation, marketing, brokerage, and scrap management services, strategically located in close proximity to our steel mills and other end-user scrap consumers, throughout the United States and Mexico. Our metals recycling operations accounted for 11% of our consolidated net sales during 2024 and 2023 and 9% during 2022. Export sales represented 17%, 19%, and 14% of metals recycling segment net sales during 2024, 2023, and 2022, respectively.

We shipped the following from our metals recycling operations:



	2024	2023	2022
Ferrous metal total (gross tons)	5,850,544	5,792,484	5,314,318
Shipments to our steel mills	3,656,034	3,593,328	3,488,206
Percent of total to our steel mills	62%	62%	66%

Nonferrous metals (thousands of pounds)	965,491	970,445	923,319

We sell various grades of processed ferrous scrap primarily to steel mills and foundries. Ferrous scrap metal is the primary raw material for EAFs, including our steel mills. In addition, we sell various grades of nonferrous metals including copper, brass, aluminum, and stainless steel, to smelters, refineries, alloy manufacturers, specialty mills and other consumers, including our aluminum operations.

We purchase processed and unprocessed ferrous and nonferrous scrap metals in a variety of forms for our metals recycling facilities.

Ferrous scrap comes from two primary sources:

●

Manufacturing industrial facilities, metal fabrication plants, and machine shops, which generate ferrous scrap referred to as prompt or industrial scrap, and

●

Scrap dealers, retail individuals, auto wreckers, demolition firms and others who provide steel and iron scrap, referred to as obsolete scrap. Obsolete scrap includes scrap recycled from end-of-life items, such as automobiles, appliances, and machinery.

Nonferrous scrap comes from three primary sources:

●

Manufacturers and other nonferrous scrap sources, which generate or sell scrap aluminum, copper, stainless steel, and other nonferrous metals,

●

Producers of items such as electric wire, telecommunication service providers, aerospace, defense, and recycling companies that generate nonferrous scrap consisting primarily of copper wire, aluminum beverage cans, and various other metals and alloys, and

●

Retail transactions conducted with the general public who sell material directly to our facilities, collected from a variety of sources.

We do not purchase a significant amount of scrap metal from a single source or from a limited number of major sources. Market demand and the composition, quality, size, weight, and location of the materials are the primary factors that determine prices.

Products. Our metals recycling operations primarily involve the purchase, processing, and resale of ferrous and nonferrous scrap metals into reusable forms and grades. We process an array of ferrous products through a variety of methods, including sorting, shredding, shearing, cutting, bailing, and breaking. Our major ferrous products include heavy

Table of Contents

melting steel, busheling, bundled scrap, shredded scrap, and other scrap metal products, such as steel turnings and cast iron. These products vary in properties or attributes related to cleanness, size of individual pieces, and residual alloys. The necessary characteristics of the ferrous products are determined by the specific needs and requirements of the consumer and affect the individual product’s relative value. We process numerous grades of nonferrous products, including aluminum, brass, copper, stainless steel, and other nonferrous metals. Additionally, we provide transportation logistics (truck, rail, and river barge), marketing, brokerage, and scrap management services, providing competitive price and cost advantages to our suppliers and customers. We design, install, and manage customized scrap management programs for industrial manufacturing companies.

Customers. We sell various grades of processed ferrous scrap to end-users, such as EAF steel mills, integrated steelmakers, foundries, secondary smelters, and metal brokers, who aggregate materials for other large users. Ferrous scrap metal is the primary raw material for EAFs, including our steel mills. Most of our ferrous scrap customers purchase processed scrap through negotiated spot sales contracts which establish a quantity purchase for the month. The price we charge for ferrous scrap depends upon market demand, composition, size, weight, and transportation costs, as well as the quality and grade of the scrap. We sell various grades of processed nonferrous scrap to end-users such as aluminum sheet and ingot manufacturers, brass and bronze ingot makers, copper refineries, mills, including our new recycled aluminum flat rolled products mill, smelters, specialty steelmakers, alloy manufacturers, wire and cable producers, and utilities. The price we charge for nonferrous scrap also depends upon market demand and pricing, transportation costs, as well as the quality and grade of the scrap.

Competition. Scrap is a global commodity influenced by conditions in a number of industrialized and emerging markets throughout Asia, Europe, and North America. The markets for scrap metals are highly competitive, both in the purchase of raw or unprocessed scrap, and the sale of processed scrap. With regard to the purchase of unprocessed scrap, we compete with numerous independent recyclers, as well as smaller scrap companies engaged only in collecting obsolete scrap. In many cases, we also purchase unprocessed scrap metal from smaller scrap dealers and other processors. Successful procurement of materials is determined primarily by the price offered by the purchaser for the raw scrap and the proximity of our processing facility to the source of the raw scrap. Both ferrous and nonferrous scrap sell as a commodity in both domestic and international markets, which are affected, sometimes significantly, by relative economic conditions, currency fluctuations, and the availability and cost of transportation. Competition for sales of processed scrap is based primarily on the price, quality, and location of the scrap metals, as well as the level of service provided in terms of reliability and timing of delivery.

We also face potential competition for sales of processed scrap from other producers of steel products, such as EAFs and integrated steel mills, some of which, like us, are also vertically connected in the scrap metals recycling business. In addition, other steel mills may compete with us in attempting to secure scrap supply through direct purchasing from our scrap suppliers. Scrap metal processors also face competition from substitutes for prepared ferrous scrap, such as pig iron, pelletized iron, hot briquetted iron (HBI), direct reduced iron (DRI), and other forms of processed iron.

The industry is highly fragmented with many small, regional, national, and global companies, which have multiple locations in areas in which our metals recycling operations operate. No single scrap metals recycler has a significant market share in the domestic market.

Other Information

Sources, Availability, and Cost of Steel and Other Operations’ Raw Materials

Scrap Metals. The principal raw material of our EAF steel operations is recycled ferrous scrap derived from, among other sources, "home scrap,” generated internally at our steel mills themselves; industrial scrap, generated as a by-product of manufacturing; obsolete scrap, recycled from end-of-life automobiles, appliances, and machinery; and demolition scrap, recycled from obsolete structures, containers, and machines.

Recycled ferrous scrap typically comprises more than 80% of the metallic melt mix in EAF steelmaking, in contrast to integrated mill steelmaking, where the proportion of scrap has traditionally been approximately 25% to 35%. Depending upon the scrap substitute material that may be available from time to time, and the relative cost of such material, the percentage of scrap used in our steelmaking operations could be increased or reduced in our metallic melt mix.

Many variables can impact ferrous scrap prices, all of which reflect the pushes and pulls of the supply-demand equation. These factors include the level of domestic steel production (high quality, low-residual scrap is a by-product of manufacturing activity), the level of exports of scrap from the United States, and the amount of obsolete scrap recycled. In addition, historical domestic ferrous scrap prices typically have a strong correlation and spread to global pig iron pricing. Generally, as domestic steel production increases, so does scrap demand and resulting scrap prices. The reverse is also normally, but not always, true with scrap prices following steel prices downward when supply exceeds demand. When scrap prices greatly accelerate, this can challenge one of the principal elements of an EAF based steel mill’s traditional lower cost structure—the cost of its metallic raw material.

Iron Units. In addition to scrap, pig iron, DRI, HBI, and internally sourced liquid pig iron are used in our EAF steel mill production. During 2024 and 2023 we consumed 13.0 million tons and during 2022 we consumed 12.0 million tons of metallic materials in our steelmaking furnaces, of which iron units other than scrap represented approximately 15% of the tons in 2024 and 2023, and 13% of the tons in 2022.

Energy Resources

Electricity. Electricity is a significant input required in our EAF steel operations, representing approximately 4% of steel production costs of goods sold in 2024, 2023, and 2022. We have entered into fixed price electricity contracts for the Butler Flat Roll Division, Columbus Flat Roll Division, Roanoke Bar Division and Steel of West Virginia, while our Engineered Bar Products Division has a combination of fixed pricing and market pricing for the various components of the electrical services (demand charge, energy charge, riders, etc.). Our Sinton Flat Roll Division purchases electricity at current market prices. Our Structural and Rail Division purchases electricity at current market prices and through fixed price forward contracts.

Research and Development

Our research and development activities have consisted of efforts to expand, develop, and improve our products and operating processes, such as our Sinton Flat Roll Division, and our efforts to develop and improve renewable product alternatives, such as our construction of a biocarbon production facility. Most of these research and development efforts have been conducted in-house by our team members.

Environmental Matters

Our operations are subject to substantial and evolving environmental, health and safety laws and regulations concerning, among other things, emissions to the air, discharges to surface and ground water and to sewer systems, and the generation, handling, storage, transportation, treatment and disposal of solid and hazardous wastes and secondary materials. Our operations are dependent upon permits regulating discharges into the environment or the use and handling of by-products in order to operate our facilities. We dedicate considerable resources aimed at achieving compliance with applicable laws concerning the environment. While we do not currently believe that our future compliance efforts with such provisions will have a material adverse effect on our results of operations, cash flows, or financial condition, this is subject to change in the ever-evolving regulatory environment in which we operate.

Since the interpretation and enforcement of environmental laws and regulations that may be enacted from time to time can be subject to changing social or political norms, our environmental capital expenditures and costs for environmental compliance may increase in the future. In addition, due to the possibility of unanticipated regulatory or other developments, the amount and timing of future environmental expenditures may vary substantially from those currently anticipated. The cost of current and future environmental compliance may also place our operations at a competitive disadvantage with respect to foreign producers, which may not be required to undertake equivalent costs in their operations.

Pursuant to the Resource Conservation and Recovery Act (RCRA), which governs the handling, recycling and disposal of solid and hazardous wastes and hazardous secondary materials, the United States Environmental Protection Agency (United States EPA) and authorized state or local environmental agencies may conduct inspections to identify alleged violations or areas where there may have been releases of solid or hazardous constituents into the environment and require the facilities to pay penalties and/or take corrective action to address any such releases. RCRA also allows citizens in certain situations to bring claims against regulated facilities for potential damages and cleanup. Many states have statutes and regulatory authorities similar to RCRA that can also apply. Many of our facilities generate wastes and secondary materials subject to these requirements. Some of these materials, for example EAF dust, may be categorized as hazardous waste, requiring special handling for disposal or for the recovery of metallics. While we cannot predict the future actions of the regulators or other interested parties, the potential exists for required corrective action, the costs of which could be substantial.

Under the Comprehensive Environmental Response Compensation and Liability Act, known as CERCLA or Superfund, the United States EPA, state agencies and, in some instances, private parties have the authority to assert joint and several liability for the remediation of contaminated properties upon generators of hazardous substances, current and former site owners and operators, transporters, and other potentially responsible parties, regardless of fault or the legality of the original disposal activity. Many states have statutes and regulatory authorities similar to CERCLA that can also apply. We have a number of material handling agreements with various contractors to properly dispose of or recycle our EAF dust and other by-products of our operations. However, we cannot assure that, even if there has been no fault by us, we may not still be cited as a hazardous substances generator by reason of an environmental cleanup at one of our facilities or a site to which our by-products were transported.

The Clean Water Act and similar state and local laws apply to aspects of our operations and impose regulatory restrictions related to the discharge of wastewater, storm water, and dredged or fill material. The United States EPA, state agencies and, in certain instances, local governments and private parties have the ability to bring claims alleging violations and seeking penalties and injunctive relief. These legal provisions can also require new or expanded water treatment investments to be made and can limit or even prohibit certain current or planned activities at our operations.

The Clean Air Act and analogous state and local laws require many of our facilities to obtain and maintain air permits in order to operate. Air permits can impose new or expanded obligations to limit or prevent current or future emissions and to add costly pollution control equipment. Claims for alleged violations can be brought by the United States EPA, state agencies, and in certain instances local governments and private parties, and can result in penalties and injunctive relief.

Table of Contents

In addition, there are a number of other environmental, health and safety laws and regulations that apply to our facilities and may affect our operations. By way of example and not of limitation, certain portions of the federal Toxic Substances Control Act, Oil Pollution Act, Safe Drinking Water Act, and Emergency Planning and Community Right-to-Know Act, as well as state and local laws and regulations implemented by the regulatory agencies, apply to aspects of our facilities’ operations. Our operations in Mexico are similarly subject to environmental requirements applicable to those operations. In some instances, we may also be subject to other foreign governments’ regulations and international treaties and laws. Many of these laws allow both the governments and citizens in certain situations to bring claims against regulated facilities for alleged environmental violations. Finally, our operations could in certain situations be subject to toxic tort claims brought by third parties alleging causes of action such as nuisance, negligence, trespass, infliction of emotional distress, or other claims alleging personal injury, property damage, or other harms.

ITEM 1A. RISK FACTORS

Many factors may have an effect on our business, results of operations, financial condition and cash flows. We are subject to various risks resulting from changing economic, environmental, regulatory, political, industry, business and financial conditions. The factors described below are some of the risks that could materially negatively impact us.

Global and National Risks Related to our Business

Our industry, as well as the industries of many of our customers and suppliers upon whom we are dependent, is affected by domestic and global economic factors including periods of slower than anticipated economic growth and the risk of a recession.

Our financial results are substantially dependent not only upon overall economic conditions in the United States and globally, including North America, Europe and in Asia, but also as they may affect one or more of the industries upon which we depend for the sale of our products. Global or domestic actions or conditions, including political actions, proposed or actual trade policies or restrictions, including tariffs or quotas, proposed or actual changes in tax laws, including the sunset of certain tax laws, proposed or actual regulation, including those related to the environment, interest rates, terrorism, acts of war or hostility, natural disasters, or pandemics, epidemics, widespread illness or other health issues, could result in changing economic conditions in the United States and globally, disruptions to or slowdowns in our business, our supply chain, or our global or domestic industry, or those of our customers or suppliers upon whom we are dependent. Additionally, periods of slower than anticipated economic growth could reduce customer confidence and adversely affect demand for our products and further adversely affect our business, results of operations, financial condition and cash flows. Metals industries have historically been vulnerable to significant declines in consumption and product pricing during periods of economic downturn or continued uncertainty.

Our business is also dependent upon certain industries, such as construction, automotive, manufacturing, transportation, heavy and agriculture equipment, energy and pipe and tube (including OCTG) markets, and these industries are also cyclical in nature and may experience supply chain disruptions. Therefore, these industries may experience their own fluctuations in demand for our products based on such things as economic conditions, interest rates, supply chain disruptions, raw material and energy costs, consumer demand, the rate of inflation and infrastructure funding decisions by governments. Many of these factors are beyond our control. As a result of volatility in our industry or in the industries we serve, we may have difficulty increasing or maintaining our level of sales or profitability. A downturn in our industry or the industries we serve may adversely affect our business, results of operations, financial condition and cash flows.

A prospective decline in consumer and business confidence and spending, which is often coupled with reductions in the availability of credit or increased cost of credit and interest rates, as well as volatility in the capital and credit markets, may adversely affect the business and economic environment in which we operate and the profitability of our business. We are also exposed to risks associated with the creditworthiness of our customers and suppliers, which during times of high interest rates can be intensified. If the availability of credit to fund or support the continuation and expansion of our customers’ business operations is curtailed or if the cost of that credit is high, the resulting inability of our customers or of their customers to either access credit or absorb the cost of that credit may adversely affect our business by reducing our sales or by increasing our exposure to losses from uncollectible customer accounts. A disruption of the credit markets could also result in financial instability of some of our customers and suppliers. The consequences of such adverse effects could include the interruption of production at the facilities of our customers, the reduction, delay or cancellation of customer orders, delays or interruptions of the supply of raw materials we purchase, and bankruptcy of customers, suppliers or other creditors. Any of these events may adversely affect our business, results of operations, financial condition and cash flows.

Global steelmaking overcapacity and imports of steel into the United States may adversely affect United States steel prices, which, together with increased scrap prices, may adversely affect our business, results of operations, financial condition and cash flows.

Global steelmaking capacity currently exceeds global consumption of steel products, which adversely affects United States and global steel prices. Such excess capacity sometimes results in steel manufacturers in certain countries exporting steel and steel products, at prices that are lower than prevailing domestic prices, and sometimes at or below their cost of production. Excessive imports of steel and steel products, into the United States, may exert downward pressure on United States steel and steel products prices, which adversely affects our business, results of operations, financial condition and cash flows. Fluctuations in the value of the dollar can also affect imports, as a strong United States dollar makes imported products less expensive, potentially resulting in more imports of steel and steel products into the United States by our foreign competitors. Furthermore, the introduction of additional domestic steel capacity could increase this global overcapacity. This, in turn, has led to and may further lead to increased domestic demand for ferrous scrap resulting in increased scrap prices. Our results of operations, financial condition and cash flows are driven primarily from the metal spread achieved from the price we sell steel and steel products compared to the price of our metallic raw materials, including scrap. During prolonged periods of steel and steel products overcapacity, leading to lower selling prices, combined with high demand for scrap and raw materials, leading to higher buying prices, our metal spreads could be compressed, which may adversely affect our business, results of operations, financial condition and cash flows.

United States steel producers compete with many foreign producers, including those in China, Vietnam and other Asian and European countries. Competition from foreign producers is typically strong and is periodically exacerbated by weakening of the economies of certain foreign steelmaking countries, at times leading to imports of steel involving dumping and subsidy abuses by foreign steel producers. Some foreign steel producers are owned, controlled or subsidized by foreign governments. As a result, decisions by these producers with respect to their production, sales and pricing are sometimes influenced to a greater degree by political and economic policy considerations than by prevailing market conditions, realities of the marketplace or consideration of profit or loss. Additionally, at times when iron ore prices are low, disruption of the scrap price correlation to iron ore may occur, which may lead to reduced global costs to produce steel, further depressing steel import prices. A higher volume of steel imports into the United States tends to occur at depressed prices when foreign steelmaking countries experience periods of economic difficulty, decreased demand for steel products or excess capacity. The global steelmaking overcapacity is exacerbated by Chinese steel production capacity that far exceeds that country’s demand and has made China a major global exporter of steel, resulting in weakened global steel pricing than otherwise would be expected. While measures to curb unfair trade such as tariffs, duties or quotas, along with trade agreements with other countries, have decreased the volume of steel and steel products imports, domestic steel and steel products prices can be negatively impacted by excessive imports of steel and steel products. Should current or new tariffs, duties or quotas expire or be relaxed, repealed or circumvented by importers of steel and steel products, or should trade agreements be renegotiated, downward pressure may be exerted on United States steel and steel products prices, which may adversely affect our business, results of operations, financial condition and cash flows.

Pandemics, epidemics, widespread illness or other health issues may adversely affect our business, results of operations, financial condition, cash flows, liquidity, and stock price.

Pandemics, epidemics, widespread illness or other health issues may adversely affect our business, results of operations, financial condition, cash flows, liquidity and stock price. Government actions globally, including United States federal and state governmental actions, related to pandemics, epidemics, widespread illness or other health issues have historically impacted demand for our products, our supply chain, our employees, the economy generally, inflation and interest rates, and any similar future actions may result in similar or additional impacts.

Industry Risks Related to our Business

Our level of production and our sales and earnings are subject to significant fluctuations as a result of the cyclical nature of the steel industry and some of the industries we serve.

The steel manufacturing business is cyclical in nature, and the selling price of the steel we make may fluctuate significantly due to many factors beyond our control. Furthermore, a number of our products are commodities, subject to their own cyclical fluctuations in supply and demand in both metal consuming and metal generating industries, including the construction and manufacturing industries. The timing, magnitude and duration of these cycles and the resulting price fluctuations are difficult to predict. The sale of our manufactured steel products is directly affected by demand for our products in other cyclical industries, such as construction, automotive, manufacturing, transportation, heavy and agriculture equipment, energy and pipe and tube (including OCTG) markets. Economic difficulties, stagnant or slow global economies, supply and demand imbalances, supply chain disruptions, periods of heightened inflation or high interest rates, and currency fluctuations in the United States or globally may decrease the demand for our products or increase the amount of imports of steel into the United States, which may decrease our sales, margins and profitability.

Volatility and major fluctuations in prices and availability of scrap metal, scrap substitutes and supplies, and our potential inability to pass higher costs on to our customers, may constrain operating levels and reduce profit margins.

Steel producers require large amounts of raw materials, including ferrous scrap metal and scrap substitute products such as pig iron and pelletized iron, and other supplies such as zinc, graphite electrodes and ferroalloys. The principal raw material of our EAF steel operations is recycled ferrous scrap derived from, among other sources, “home scrap,” generated internally at steel mills themselves; industrial scrap, generated as a by-product of manufacturing; obsolete scrap, recycled from end-of-life automobiles, appliances and machinery; and demolition scrap, recycled from obsolete structures, containers and machines. The prices for scrap are subject to market forces largely beyond our control, including demand by United States and foreign steel producers, freight costs and speculation. The scrap metal recycling industry has historically been, and is expected to remain, highly cyclical and the prices for scrap have varied significantly in the past, may vary significantly in the future and do not necessarily fluctuate in tandem with the price of steel. Moreover, some of our integrated steel producer competitors are not as dependent as we are on ferrous scrap as a part of their raw material melt mix, which, during periods of high scrap costs relative to the cost of blast furnace iron used by the integrated producers, give them a raw material cost advantage over EAF mills. However, given environmental considerations of investors, customers and regulators, additional EAF mills may be constructed, or companies currently operating blast furnace mills may invest in EAF mills, leading to increased demand in ferrous scrap possibly resulting in higher scrap prices. While our vertical integration into the metals recycling business and our liquid pig-iron operations are expected to enable us to continue being a cost-effective supplier to our own steelmaking operations, for some of our metallics requirements, we still rely on other metallics and raw material suppliers, as well as upon general industry supply conditions for the balance of our needs.

The availability and prices of raw materials and supplies, particularly those with positive environmental attributes, may also be negatively affected by new, existing or changing laws, regulations, sanctions or embargoes, including those that may impose output limitations or higher costs associated with climate change or GHG allocation by suppliers, interruptions in production, accidents or natural disasters, changes in exchange rates, global price fluctuations, the availability and cost of transportation, and competing uses, all of which may be heighted during times of war or hostilities. As a major producer of galvanized steel products, we purchase and consume a large amount of zinc, which if purchased at high prices, may adversely affect our profit margins. Any inability to secure a consistent, cost-effective and timely supply of our raw materials and supplies may adversely affect our business, financial condition, results of operations and cash flows.

Additionally, our inability to pass on all or a substantial part of any cost increases, whether due to positive environmental attributes, inflation, supply and demand imbalances, or otherwise, or to provide for our customers’ needs because of the potential unavailability of raw materials, supplies or required environmental attributes, may result in production slowdowns or curtailments or may otherwise adversely affect our business, financial condition, results of operations and cash flows.

The cost and availability of electricity, natural gas, oil and other energy resources are subject to volatile market conditions.

We consume large amounts of energy to melt scrap, reheat semi-finished products for rolling into finished products and perform other steps necessary to our production process. We rely on third parties for the supply of energy resources we require in our production activities. The prices for and availability of electricity, natural gas, oil and other energy resources, including renewable or other clean energy sources, are subject to regulation and volatile market conditions, often affected by weather conditions as well as political, environmental and economic factors beyond our control. As large consumers of electricity and natural gas, we must have dependable delivery in order to operate. Accordingly, we are at risk in the event of an energy disruption, including power outages, power unavailability or inability to obtain power at a reasonable price or with sufficient desired environmental attributes. Prolonged blackouts, curtailments or disruptions caused by natural disasters or by political or environmental considerations would substantially disrupt our production. Since a significant portion of our finished products are delivered by truck, unforeseen fluctuations in the price of fuel would also adversely affect our costs or the costs of many of our customers.

Increased environmental, GHG emissions and sustainability considerations from our customers and investors or related regulations could affect demand for our products and add significant costs.

Customers, investors and regulators have increased their focus on the environment, GHG emissions and sustainability. We are committed to the environment and sustainability. We are taking further action to reduce our environmental footprint through our 2025, 2030, and 2050 goals for GHG emission reduction and increased renewable energy usage. We believe that achievement of these goals will comport with expectations of our customers and investors, but certain customers and investors may have differing requirements. To achieve these goals, our operational costs may increase and we have had and will continue to have additional capital expenditures, some of which we may not be able to pass along to our customers. Any failure to timely meet these goals, or other requirements of customers or investors, may have an adverse effect on our business, results of operations and stock price.

Additionally, governmental agencies, regulators, investors or other groups have introduced, and may request or require, environmental monitoring, disclosures or regulations in response to the potential impacts of climate change. International treaties or agreements may also result in increasing regulation of GHG emissions, including carbon emissions limitations or trading mechanisms. Any such regulation or disclosure requirement could impose significant costs on our operations and on the operations of our customers and suppliers, including increased energy, capital equipment, emissions controls, environmental monitoring and reporting and other costs in order to comply with current or future laws, regulations or demands concerning the environment, climate change, GHG emissions and sustainability. Any adopted regulations could negatively impact our ability, and that of our customers and suppliers, to compete with companies situated in areas not subject to or not complying with such regulations, or could affect our environmental disclosures for any allowances, offsets or credits. We may see an increase in costs relating to our assets that emit GHGs as a result of these initiatives, which may impact our operations directly or through our customers and suppliers.

Compliance with and changes in environmental and remediation requirements may result in substantially increased capital requirements and operating costs.

Existing laws or regulations, as currently interpreted or as may be interpreted in the future, as well as future laws or regulations, may adversely affect our results of operations and financial condition.

We are subject to numerous local, state, federal and international statutory and regulatory environmental requirements relating to, among other things:

●the generation, storage, treatment, handling and disposal of solid and hazardous wastes and secondary materials;

●

the discharge of materials into the air, including periodic changes to the National Ambient Air Quality Standards and to emission standards;

●the management, treatment and discharge of wastewater and storm water;

Table of Contents

●the use and treatment of groundwater;

●the remediation of soil and groundwater contamination;

●climate change legislation or regulation;

●the need for and the ability to timely obtain air, water or other environmental permits;

●the timely reporting of certain chemical usage, content, storage and releases;

●the remediation and reclamation of land used in our operations;

●natural resource protections; and

●the protection of our employees’ health and safety.

Compliance with environmental laws and regulations, which affect our EAF steelmaking, metals recycling, liquid pig-iron, and copper and aluminum production operations, is a significant factor in our business. We are required to obtain and comply with environmental permits and licenses, and failure to obtain or renew or the violation of any permit or license may result in substantial fines and penalties, capital expenditures, operational changes, suspension of operations or the closure of a subject facility. Similarly, delays, increased costs or the imposition of onerous conditions to the securing or renewal of permits may adversely affect these operations.

Uncertainty regarding adequate pollution control levels, testing and sampling procedures, and new pollution control technology are factors that may increase our future compliance expenditures. We are unable to predict the ultimate cost of future compliance with environmental requirements or their effect on our operations. Although we strive to be in substantial compliance with all applicable laws and regulations, legal requirements frequently change and are subject to interpretation such that regulatory agencies may bring enforcement actions for alleged noncompliance. Private parties might also bring claims against us under citizen suit provisions and/or for property damage or personal injury allegedly resulting from our operations. New laws, regulations and changing interpretations by regulatory authorities, together with uncertainty regarding the application of existing requirements, are among the factors that may increase our future expenditures to comply with environmental requirements. The cost of complying with existing laws or regulations as currently interpreted or reinterpreted in the future, or with future laws or regulations, may adversely affect our results of operations and financial condition.

Our operations produce significant amounts of by-products, some of which are handled as solid or hazardous waste or as hazardous secondary materials. For example, our steel mills generate EAF dust, which the United States Environmental Protection Agency (United States EPA) and other regulatory authorities classify as hazardous waste and regulate accordingly unless recycled in an exempt manner.

In addition, the feed materials for the shredders operated by our metals recycling operations include automobile bodies. A portion of the feed materials consist of currently unrecyclable material known as shredder residue. If laws or regulations or the interpretation of the laws or regulations change with regard to EAF dust or shredder residue or other by-products created by our operations, we may incur significant additional expenditures.

Federal and state environmental laws enable federal and state agencies and certain private parties to recover from owners, operators, generators and transporters the cost of investigation and cleanup of sites at which wastes or hazardous substances were disposed and/or migrated. In connection with these laws, we may be required to clean up contamination discovered at our sites including contamination that may have been caused by former owners or operators of the sites, to conduct additional cleanup at sites that have already had some cleanup performed, to address emerging and newly-regulated contaminants such as per- and polyfluoroalkyl substances (PFAS) and 1,4-dioxane, or to perform cleanup with regard to sites formerly used in connection with our operations.

In addition, we may be required to pay for, or to pay a portion of, the costs of cleanup at sites to which we sent materials for disposal or recycling, notwithstanding that the original disposal or recycling activity may have complied with all regulatory requirements then in effect. Under certain laws, a party can be held jointly and severally liable for all of the cleanup costs associated with a disposal site. In practice, a liable party often splits the costs of cleanup with other

Table of Contents

potentially responsible parties. We have received notices from the United States EPA, state agencies and third parties that we have been identified as potentially responsible for the costs of investigating and cleaning up a number of disposal sites. In most cases, many other parties are also named as potentially responsible parties and also contribute to payment of those costs.

Because cleanup liability can in some cases be imposed retroactively on activities that occurred many years ago, and because federal and state agencies are still discovering sites that pose a threat to public health or the environment, we can provide no assurance that we will not become liable for significant costs associated with investigation and remediation of cleanup sites.

Operational and Commercial Risks Related to our Business

We may face significant price and other forms of competition from other steel and aluminum producers, scrap processors and alternative materials, which may adversely affect our business, financial condition, results of operations and cash flows.

The global markets in which steel companies and scrap processors conduct business are highly competitive and became even more so due to consolidations in the steel and scrap industries. Additionally, in many applications, steel competes with other materials, such as aluminum, cement, composites, plastics, carbon fiber, glass and wood. Increased use of alternative materials for any reason, including as a response to regulations or customer demands, could decrease demand for steel or force other steel producers into new products or markets that compete more directly with us, and combined with increased competition could cause us to lose market share, increase expenditures or reduce pricing, any one of which may adversely affect our business, financial condition, results of operations and cash flows.

Additionally, our recycled aluminum flat rolled products mill with an anticipated annual production capacity of 650,000 metric tons of finished products located in Columbus, Mississippi is expected to produce commercially viable products by mid-year 2025. Although we anticipate being able to effectively compete in the aluminum industry, along with the other risks described herein, including delays or difficulties with our start-up, we may face unexpected and enhanced competition, which may adversely affect the expected contributions of our aluminum operations and our resulting business, financial condition, results of operations and cash flows.

Availability of an adequate source of supply of scrap is required for our metals recycling operations.

We procure our scrap inventory from numerous sources. These suppliers generally are not bound by long-term contracts and generally have no obligation to sell recyclable metal to us. In periods of low industry scrap prices, scrap suppliers may elect to hold recyclable metal to wait for higher prices or intentionally slow their metal collection activities. If a substantial number of scrap suppliers cease selling recyclable metal to us, we may be unable to recycle metal at desired levels which may adversely affect our results of operations and financial condition. In addition, a slowdown of industrial production in the United States reduces the supply of industrial grades of metal to the metals recycling industry, resulting in our having less recyclable metal available to process and sell. Further, additional EAF steel mill construction or blast furnace mills investing in EAF mills could increase the demand for scrap, potentially resulting in higher scrap prices or periods of decreased scrap supply. Any inability to secure scrap for our EAF steel mills could adversely affect our business, results of operations, financial condition and cash flows.

We are subject to cybersecurity threats and may face risks to the security of our sensitive data and information technology which may adversely affect our business, results of operations, financial condition and cash flows.

Increased cybersecurity and information technology security requirements, vulnerabilities and threats and a rise in sophisticated and targeted cybercrime, all of which may be heightened during times of war or hostilities, pose a risk to the security and functionality of our systems and information networks, and to the confidentiality, availability and integrity of sensitive data, including intellectual property, proprietary information, financial information, customer and supplier information, and personally identifiable information. Additionally, cybersecurity vulnerabilities or attacks could result in an interruption of the functionality of our automated and electronically controlled manufacturing operating systems, which, if compromised, could cease, threaten, delay or slow down our ability to melt, roll or otherwise process

Table of Contents

steel or any of our other products for the duration of such interruption. Our customers and suppliers may also store certain of our sensitive information on their information technology systems, which if breached or attacked, could likewise expose our sensitive information. Similarly, information system vendors and software suppliers may experience a cybersecurity or information technology breach that exposes our systems or sensitive data. Any of these cybersecurity and information technology breaches or disruptions may result in reputational harm and may adversely affect our business, results of operations, financial condition and cash flows.

Although we believe we have adopted procedures, training programs, and controls to adequately protect our sensitive data, networks and information and operating technology and systems, there can be no assurance that a system or network failure, or cybersecurity breach or attack, will be prevented, whether due to attacks by cyber criminals or due to employee, contractor or other error or malfeasance. This could lead to system interruption, production delays or downtimes and operational disruptions, and the disclosure, modification or destruction of sensitive data, which may adversely affect our reputation, customer and supplier relationships, financial results and results of operations, and could result in litigation or regulatory investigations, actions, fines or penalties, as well as increased cybersecurity monitoring and protection costs, including the cost or availability of insurance. Additionally, as cybersecurity threats continue to evolve and become more sophisticated, we may need to invest additional time, resources and finances to protect the security of our sensitive data, systems and information networks. We maintain an information security risk insurance policy to mitigate the impact of cybersecurity threats.

We may face risks associated with the implementation of our growth strategy.

Our growth strategy subjects us to various risks. As part of our growth strategy, we may expand existing facilities, enter into new business lines, territories, products or process initiatives, acquire or build additional plants, acquire other businesses and assets, enter into joint ventures, or form strategic alliances that we believe will complement our existing business. These expansions and transactions, including our recycled aluminum flat rolled products mill with an anticipated annual production capacity of 650,000 metric tons of finished products located in Columbus, Mississippi, may involve some or all of the following risks:

● the risk of entering business lines or product, domestic, or foreign markets, in which we have little experience, including the aluminum industry;

● the risk of a newly constructed facility being completed over budget or not on time, including due to equipment delays or labor shortages, or having delays or difficulties with its start-up;

● the risk of not being able to adequately obtain sufficient labor to efficiently build or staff a new facility, while maintaining our culture;

● the risk of expected markets, products, customers and demand for products produced by a new facility being lower than expected;

● the risk of new product development, technology development or customer acquisition and penetration being more costly or difficult than expected;

● the difficulty of competing for acquisitions and other growth opportunities with companies having materially greater financial resources than us;

● the inability to realize anticipated synergies or other expected benefits;

● the difficulty of integrating new or acquired operations and personnel into our existing operations, while maintaining our culture;

● the potential disruption of ongoing operations;

● the diversion of financial resources or management attention to new operations or acquired businesses;

Table of Contents

● the loss of key employees, customers or suppliers of acquired businesses;

● the potential exposure to unknown liabilities;

● the inability of management to maintain uniform standards, controls, procedures and policies;

● the difficulty of managing the growth of a larger company;

● the risk of becoming involved in labor, commercial, or regulatory disputes or litigation related to new operations or acquired businesses;

● the risk of becoming more highly leveraged;

● the risk of contractual or operational liability to other venture participants or to third parties as a result of our participation;

● the inability to work efficiently with joint venture or strategic alliance partners; and

● the difficulties of terminating joint ventures or strategic alliances.

Delays in achieving full operational capacity at our Sinton Flat Roll Division has and may continue to, and any delays in our recycled aluminum flat rolled products mill may, adversely affect our prospects, business, financial condition, results of operations and cash flows.

These expansions or transactions might be required for us to remain competitive, but we may not be able to complete any such expansions or transactions on favorable terms or obtain financing, if necessary. Future expansions and transactions may not improve our competitive position and business prospects as anticipated, and if they do not, our business, financial condition, results of operations and cash flows may be adversely affected.

We may face risks associated with our ability to retain, develop and attract key personnel.

Our people are the foundation of our success and are our most important resource. Their continued education and talent development are paramount to our success. As we continue to grow, our success depends in part on our ability to retain, develop and attract team members with relevant industry and technical experience, while maintaining our culture. A loss of senior managers or other key personnel, without adequate replacement, which could be exacerbated by a shortage of skilled workers and our more senior workforce, could adversely affect our business and results of operations.

We are subject to litigation and legal compliance risks which may adversely affect our financial condition, results of operations and liquidity.

We are involved from time to time in various litigation matters, including administrative proceedings, regulatory proceedings, governmental investigations, environmental matters, and commercial and construction contract disputes, none of which are currently expected to have a material impact on our financial conditions, results of operations or liquidity. For additional information regarding legal proceedings please refer to Item 3. Legal Proceedings.

In addition to risks associated with our environmental and other regulatory compliance, our international operations are subject to complex foreign and United States laws and regulations, including the Foreign Corrupt Practices Act and other anti-bribery laws, regulations related to import-export controls, the Office of Foreign Assets Control, and other laws and regulations, each of which may increase our cost of doing business and expose us to increased risk.

Unexpected equipment downtime or shutdowns may adversely affect our business, financial condition, results of operations and cash flows.

Table of Contents

Interruptions in our production capabilities may adversely affect our production costs, products available for sale and earnings during the affected period. In addition to equipment failures, our facilities are subject to the risk of catastrophic loss due to unanticipated events such as fires, explosions or violent weather conditions. Our manufacturing processes are dependent upon critical pieces of steelmaking equipment, such as our EAFs, continuous casters and rolling equipment, some of which are controlled by our information technology systems, as well as electrical equipment, such as transformers. This equipment may, on occasion, be out of service as a result of unanticipated failures or other events, including equipment failure, power surges, cybersecurity breaches or attacks or system failures. Further, we have experienced and may continue to experience inefficiencies at our Sinton Flat Roll Division, including those related to major equipment failures. We have experienced and in the future may experience plant shutdowns or periods of reduced production as a result of equipment failures or other events. Supply chain disruptions and labor shortages have and may continue to exacerbate the effects of equipment failures. These disruptions may adversely affect our business, financial condition, results of operations and cash flows.

Governmental agencies may refuse to grant or renew some of our licenses and permits required to operate our businesses.

Some of our operations must receive licenses and air, water and other permits and approvals from federal, state and local governments to conduct certain of our operations or to build, expand or acquire new facilities. Governmental agencies, non-governmental organizations, and members of the public sometimes resist the establishment of certain types of facilities in their communities. There can be no assurance that future approvals, licenses and permits will be granted or that we will be able to maintain and renew the approvals, licenses and permits we currently hold. Failure to do so may adversely affect our business, financial condition, results of operations and cash flows.

Our senior unsecured credit facility contains, and any future financing agreements may contain, restrictive covenants that may limit our flexibility.

Restrictions and covenants in our existing debt agreements, including our senior unsecured credit facility, and any future financing agreements, may impair our ability to finance future operations or capital needs or to engage in other business activities. A breach of any of the restrictions or covenants could cause a default under our senior unsecured credit facility, our senior notes, or our other debt. A significant portion of our indebtedness may then become immediately due and payable.

Under our senior unsecured credit facility, we are required to maintain certain financial covenants. Our ability to meet such covenants or other restrictions can be affected by events beyond our control. If a default were to occur, the lenders could elect to declare all amounts then outstanding to be immediately due and payable and terminate all commitments to extend further credit.

Impairment charges may adversely affect our results of operations.

Occasionally, assumptions that we have made regarding products or businesses we have acquired or sought to develop, about the sustainability of markets we sought to exploit, or about industry conditions that underlie our decision making when we elected to capitalize a venture turn out differently than anticipated. In such instances, the fair value of such assets may fall below their carrying value recorded on our balance sheet.

Accordingly, we periodically test goodwill, and other assets such as long-lived tangible assets and intangible assets, right of use assets and equity method investments when indicators of impairment are present, to determine whether their estimated fair value is in fact less than their value recorded on our balance sheet. If we determine that the fair value of any of these assets, from whatever cause, is less than the value recorded on our balance sheet, we are required to incur non-cash asset impairment charges that adversely affect our results of operations. There can be no assurances that market dynamics or other factors may not result in future impairment charges.

ITEM 1C. CYBERSECURITY

We manage risks from cybersecurity threats through our overall companywide risk management process, which is overseen by our Board of Directors and specific Board Committees. Management has created a global information security program, which encompasses a dedicated global information security team and policies, procedures, and processes for assessing, identifying, and managing risks from cybersecurity threats. Our policies, procedures, and processes follow recognized frameworks established by the National Institute of Standards and Technology (“NIST”), as well as other relevant standards. Our program is designed to maintain the confidentiality, integrity, security, and availability of the data that is created, collected, stored, and used to operate our business.

Risk Management and Strategy

We recognize the importance of assessing, identifying, and managing material risks associated with cybersecurity threats, utilizing, from time to time, tabletop exercises, business unit assessments, threat modeling, impact analyses, internal audits, external audits, third party vulnerability scans, third party penetration tests, and engagement of third parties to conduct analysis of our information security programs, including an overall assessment utilizing the NIST standards. These risks include, among other things: operational risks, intellectual property theft, fraud, extortion, harm to team members or customers, and violations of data privacy or security laws.

Our Director of Information Security is responsible for leading the Information Security Team which has established a cybersecurity risk management program of policies and processes for assessing, identifying, and managing risk from cybersecurity threats. We have integrated these processes into our overall risk management systems and processes, and routinely assess risks from cybersecurity threats, including any potential unauthorized access to or activity conducted through our information systems that may result in material adverse effects on the confidentiality, integrity, or availability of our information systems or any information residing therein. This program includes established reasonable safeguards to minimize the identified risks; processes to reasonably address any identified gaps in existing safeguards; updates to existing safeguards as necessary; and monitoring the effectiveness of those safeguards.

Our safeguards include continuous network monitoring, complex passwords, team member training that reinforces our policies, standards, and practices, incident response capability reviews and exercises, and cybersecurity insurance and disaster recovery plans for the protection of our assets. The information security training and awareness program engages personnel through training modules on how to identify potential cybersecurity risks and protect the Company’s resources and information. This training is mandatory for all team members monthly, and is supplemented by companywide testing initiatives, including periodic phishing tests.

Our cybersecurity risk management program also assesses third party providers, such as vendors, suppliers, and other business partners. Cybersecurity risks are evaluated when determining the selection and oversight of applicable third party providers and potential risks when handling or processing our employee, business, or customer data.

Further, we have designated a member of our senior leadership team, our Chief Financial Officer, to oversee the management of the safeguards, cybersecurity risk assessment, and mitigation process. From time to time, the Company’s program is reviewed and validated by internal and external experts.

In general, our incident response process follows the NIST framework and focuses on four phases: (i) preparation; (ii) detection and analysis; (iii) containment, eradication, and recovery; and (iv) post-incident remediation. As cybersecurity incidents occur, including at third party providers, the Director of Information Security leads the Information Security Team through a standardized incident response process that focuses on responding to and containing the threat, minimizing any business impact, and evaluating its severity level. The severity level assessment determines how widespread the incident is and to what degree it could impact our overall business and manufacturing environment. In the event an incident is determined by the Information Security Team to be a high severity level, our cross functional team, with expertise in various disciplines, will assess the incident to determine if it has had a material affect or is reasonably likely of having a material effect on the Company’s business strategy, results of operations, or financial condition.

Table of Contents

We do not believe that risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected or are reasonably likely to materially affect our overall business strategy, results of operations, or financial condition over the long term. In the last three years, the Company has not been aware of any material cybersecurity incidents occurring and we have not incurred material expenses from cybersecurity incidents (including penalties and settlements, of which there were none). For additional discussion of whether and how risks from cybersecurity threats could materially affect or are reasonably likely to materially affect the Company, see Item 1A. Risk Factors – “We are subject to cybersecurity threats and may face risks to the security of our sensitive data and information technology which may adversely affect our business, results of operations, financial condition and cash flows.”

Governance

One of the key functions of our Board of Directors is informed oversight of our risk management process, including risks from cybersecurity threats. Our Board of Directors is responsible for monitoring and assessing strategic risk exposure, and our senior leadership team is responsible for the day-to-day management of the material risks we face. Our Board of Directors administers its cybersecurity risk oversight function directly as a whole, as well as directly through the Audit Committee. Management and members of the Information Security Group (“ISG”) regularly present to the Board of Directors regarding information security and an in-depth review of our processes for assessing, identifying, and managing material risks from cybersecurity threats. On a quarterly basis, the Audit Committee is informed by management concerning the status of existing and new cybersecurity risks, status of how management is addressing and mitigating those risks, cybersecurity and data privacy incidents (if any), and status of key information security initiatives. Additionally, on a biennial basis, we engage third parties to assess our information security program using the NIST framework, as well as perform penetration testing.

We have allocated substantial cross functional internal resources with expertise in information security, information technology, operations, risk management, human resources, finance, and legal to form a governance counsel known as the ISG. The ISG is an internal working group that collaborates with the Director of Information Security to ensure our cybersecurity program is adequately responsive to the evolving threat landscape. Our Director of Information Security has over twenty years of cybersecurity experience, has completed a Masters in Homeland Security, with an emphasis on cybersecurity, and holds several cybersecurity certifications.

Operating Statement Classifications

Net Sales. Net sales from our operations are a factor of volumes shipped, product mix, and related pricing. We charge premium prices for certain grades of steel, product dimensions, certain smaller volumes, and for value-added processing or coating of our steel products. Except for the steel fabrication operations, we recognize revenues from sales and the allowance for estimated returns and claims from these sales at the point in time control of the product transfers to the customer, upon shipment or delivery. Our steel fabrication operations recognize revenues over time based on completed fabricated tons to date as a percentage of total tons required for each contract.

Costs of Goods Sold. Our costs of goods sold represent all direct and indirect costs associated with the manufacture of our products. The principal elements of these costs are scrap and scrap substitutes (which represent the most significant single component of our consolidated costs of goods sold), steel substrate, direct and indirect labor and related benefits, alloys, zinc, transportation and freight, repairs and maintenance, utilities such as electricity and natural gas, and depreciation.

Table of Contents

Selling, General and Administrative Expenses. Selling, general and administrative expenses consist of all costs associated with our sales, finance and accounting, and administrative departments, including, among other items, labor and related benefits, and professional services.

Companywide profit sharing and amortization of intangible assets are each separately presented in the statements of income.

Interest Expense, net of Capitalized Interest. Interest expense consists of interest associated with our senior credit facilities and other debt, net of interest costs that are required to be capitalized during the construction period of certain capital investment projects.

Other (Income) Expense, net. Other income consists of interest income earned on our temporary cash deposits, short-term and other investments, and any other non-operating income activity, including income from investments in unconsolidated affiliates accounted for under the equity method. Other expense consists of any non-operating costs, such as certain acquisition and financing expenses.

2024 Overview

During 2024 we achieved steel shipments of 12.7 million tons, our second highest annual volume behind 2023’s 12.8 million tons. Underlying domestic steel demand was stable during 2024, but imports of certain steel products, most notably coated flat rolled steels, caused pricing pressure for flat rolled steel products. While facing a challenging pricing environment throughout much of the year, our metals recycling teams maintained consistent volumes during 2024 compared to 2023. A solid non-residential construction market during 2024 benefited our steel fabrication operations, as the segment achieved historically strong volumes and average selling prices, compared to pre-Covid levels. Consolidated net sales were $17.5 billion during 2024, with cash flow from operations of $1.8 billion. Metal spread compression in our steel and, particularly, steel fabrication segments resulted in significantly lower operating income in 2024 compared to 2023.

Consolidated operating income for 2024 decreased $1.2 billion, or 38%, to $1.9 billion, compared to $3.2 billion in 2023. Net income attributable to Steel Dynamics, Inc. for 2024 decreased $913.7 million, or 37%, to $1.5 billion, compared to 2023. Diluted earnings per share attributable to Steel Dynamics, Inc. was $9.84 for 2024, compared to $14.64 for 2023.

Refer to Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations in Part II of our Annual Report on Form 10-K for the year ended December 31, 2023, for additional information regarding results of operations for the year ended December 31, 2023, as compared to the year ended December 31, 2022, and segment operating results for 2023 as compared to 2022.

Segment Results 2024 vs. 2023

During 2024, our steel operations achieved annual shipments of 12.7 million tons (11.4 million excluding intra-segment), slightly less than 2023 total record shipments. Customer order activity and steel demand were stable during 2024, with the construction, automotive, industrial, and energy sectors leading demand. In spite of strong market demand, average selling prices were lower during 2024 compared to 2023, as total steel segment average selling prices decreased 4%, or $46 per ton, compared to 2023. Net sales for the steel operations segment were 4% lower in 2024 when compared to 2023, due to lower average steel selling prices on consistent volumes.

Table of Contents

Metallic raw materials used in our electric arc furnaces represent our single most significant steel manufacturing cost, generally comprising approximately 55% to 65% of our steel mill operations’ manufacturing costs. Our metallic raw material cost consumed in our steel mills decreased $28 per net ton, or 7%, in 2024 compared to 2023, consistent with overall decreased domestic scrap pricing noted below in the metals recycling operations segment discussion.

As a result of average selling prices decreasing more than scrap costs, specifically for long products, metal spread (which we define as the difference between average steel mill selling prices and the cost of ferrous scrap consumed in our steel mills) decreased 3% in 2024 compared to 2023. Due to metal spread compression, operating income for the steel operations decreased 16% to $1.6 billion in 2024 compared to 2023.

Metals Recycling Operations Segment

Metals recycling operations include our OmniSource ferrous and nonferrous processing, transportation, marketing, brokerage, and scrap management services primarily throughout the United States and Mexico. Our steel mills utilize a large portion of the ferrous scrap sold by our metals recycling operations as raw material in our steelmaking operations, and the remainder is sold to other consumers, such as other steel manufacturers and foundries. In 2024 and 2023, 62% of metals recycling operations ferrous scrap was sold to our own steel mills, while our steel mill utilization remained consistent at 81% and 82% in 2024 and 2023, respectively. Metals recycling operations accounted for 11% of our consolidated net sales during 2024 and 2023.

Segment Results 2024 vs. 2023

During 2024, our metals recycling operations continued to benefit from solid domestic steel industry demand, resulting in consistent ferrous and nonferrous scrap shipments compared to 2023. Net sales for our metals recycling operations in 2024 were comparable to 2023 based on consistent shipments. Due to a challenging pricing environment throughout much of 2024, ferrous average selling prices decreased 7% while nonferrous average selling prices increased 10% during 2024 compared to 2023.

Ferrous metal spread (which we define as the difference between average selling prices and the cost of purchased scrap) was flat and nonferrous metal spread increased 13% during 2024 compared to 2023. As a result of the overall increased metals spreads, metals recycling operations operating income increased 61% to $76.8 million in 2024 compared to 2023.

Steel Fabrication Operations Segment

Steel fabrication operations include the company’s New Millennium Building Systems’ joist and deck plants located throughout the United States, and in Northern Mexico. Revenues from these plants are generated from the fabrication of girders, steel joists and steel deck used within the non-residential construction industry. Steel fabrication operations accounted for 10% and 15% of our consolidated net sales during 2024 and 2023, respectively.

Segment Results 2024 vs. 2023

Net sales for the steel fabrication operations decreased 37% during 2024 compared to 2023, as average selling prices decreased 31% and volumes decreased 8% compared to 2023. Our steel fabrication operations benefited from a solid non-residential construction market, as evidenced by historically solid order backlog that extends deep into the first half of 2025 at attractive pricing levels. The continued onshoring of manufacturing, coupled with the robust U.S. infrastructure and Inflation Reduction Act programs, supports consistent strong demand for steel joist and deck products.

The purchase of various steel products is the largest single cost of production for our steel fabrication operations, historically representing approximately two-thirds of the total cost of manufacturing. The average cost of steel consumed decreased 5% in 2024, as compared to 2023. Due to decreased selling prices per ton more than offsetting decreased steel input costs per ton, metal spread (which we define as the difference between average selling prices and the cost of purchased steel) contracted 41% in 2024 compared to 2023. Metal spread compression coupled with decreased volume resulted in operating income decreasing 58% to $667.0 million in 2024, compared to $1.6 billion in 2023.

Table of Contents

Aluminum Operations Segment

Aluminum operations include the recycled aluminum flat rolled products mill nearing completion of construction in Columbus, Mississippi, two satellite recycled aluminum slab centers in the southwest United States (US) and Central Mexico, and an entity with aluminum operations, formerly included in the results of our metals recycling operations segment. The aluminum flat rolled products mill and the Mexico and US recycled aluminum slab centers are expected to begin operations in mid to late 2025. Net sales relate to an entity with aluminum operations, previously reported as part of our metals recycling operations. The results of this segment largely consist of construction and start-up costs recorded in selling, general, and administrative expenses, which continued to increase during 2024, consistent with increased headcount and start-up costs.

Other Operations

Consolidated Results 2024 vs. 2023

Selling, General and Administrative Expenses. Selling, general and administrative expenses of $664.1 million during 2024 increased 13% from $588.6 million during 2023 primarily due to an increase in payroll and benefits expense related to the growth of the aluminum operations segment during 2024. Selling, general and administrative expenses represented 3.8% and 3.1% of net sales during 2024 and 2023, respectively.

Profit sharing expense during 2024 of $164.9 million decreased 39% from $272.0 million during 2023, consistent with decreased pretax earnings. This decrease in profit sharing expense was the primary driver of decreased operating loss for other operations of 20% in 2024 compared to 2023. Profit sharing expense for eligible employees is 8% of consolidated pretax income excluding noncontrolling interests and other items. Refer to Note 10. Retirement Plans to the consolidated financial statements elsewhere in this report for further information.

Interest Expense, net of Capitalized Interest. During 2024, interest expense of $56.3 million decreased 26% from $76.5 million during 2023. The lower interest expense in 2024 compared to 2023 is due to higher capitalized interest in 2024 ($66.8 million, compared to $33.0 million in 2023) related to our ongoing expansion projects, most notably within Aluminum Operations.

Other (Income) Expense, net. Net other income was $96.2 million in 2024, compared to $144.2 million in 2023, due primarily to the impact of foreign currency exchange rate losses of $18.7 million in 2024 compared to gains of $10.5 million in 2023, as well as a $21.8 million reduction in interest income on investments in 2024 compared to 2023 due to a decrease in the balance of invested cash during 2024.

Income Tax Expense. During 2024, income tax expense of $432.9 million, at an effective income tax rate of 21.8%, decreased 42% compared to the $751.6 million, at an effective income tax rate of 23.3%, during 2023, consistent with decreased pretax earnings. Our effective tax rate decrease was due primarily to certain discrete tax adjustments during the third quarter and fourth quarters of 2024. Refer to Note 4. Income Taxes to the consolidated financial statements elsewhere in this report for additional information.

Included in the balance of unrecognized tax benefits at December 31, 2024, are potential benefits of $26.4 million that, if recognized, would affect the effective tax rate. We recognize interest and penalties related to our tax contingencies on a net-of-tax basis in income tax expense. During the year ended December 31, 2024, we recognized expense from the increase of interest expense and penalties of $710,000, net of tax. In addition to the unrecognized tax benefits noted above, we had $4.2 million accrued for the payment of interest and penalties at December 31, 2024.

We file income tax returns in the United States federal jurisdiction as well as income tax returns in various state jurisdictions. The tax years 2021 through 2023 remain open to examination by the Internal Revenue Service and various state and local jurisdictions. At this time, we do not believe there will be any significant examination adjustments that would result in a material change to our financial position, results of operations or cash flows. It is reasonably possible that the amount of unrecognized tax benefits could change in the next twelve months in an amount ranging from zero to $12.0 million, as a result of the expiration of the statute of limitations and other federal and state income tax audits.

Liquidity and Capital Resources

Capital Resources and Long-term Debt. Our business is capital intensive and requires substantial expenditures for, among other things, the purchase and maintenance of equipment used in our operations, and to remain in compliance with environmental laws. Our short-term and long-term liquidity needs arise primarily from working capital requirements, capital expenditures, including expansion projects, principal and interest payments related to our outstanding indebtedness, dividends to our shareholders, potential stock repurchases and acquisitions or investments. We have met and intend to continue to meet these liquidity requirements primarily with available cash and cash provided by operations, long-term borrowings, and we also have availability under our unsecured Revolver. Our liquidity at December 31, 2024, is as follows (in thousands):



Cash and equivalents	$	589,464
Short-term and other investments		388,563
Unsecured revolver availability		1,190,741
Total liquidity	$	2,168,768

Our total outstanding debt of $3.2 billion increased $160.0 million compared to December 31, 2023, due to our issuance of $600.0 million of senior unsecured notes in July 2024 as described in Note 3, the proceeds of which were used for general corporate purposes, including the repayment of our 2.800% senior notes due December 2024, working capital, capital expenditures, advances for or investments in subsidiaries, acquisitions, redemption and repayment of other outstanding indebtedness, and purchases of the company’s common stock. Our total long-term debt to capitalization ratio (representing our long-term debt, including current maturities, divided by the sum of our long-term debt, redeemable noncontrolling interests, and our total stockholders’ equity) was 26.5% and 25.8% at December 31, 2024 and 2023, respectively.

Our unsecured credit agreement has a senior unsecured revolving credit facility (Facility), which provides a $1.2 billion Revolver and matures in July 2028. Subject to certain conditions, we have the ability to increase the Facility size by $500.0 million. The unsecured Revolver is available to fund working capital, capital expenditures, and other general corporate purposes. The Facility contains financial covenants and other covenants pertaining to our ability to incur indebtedness and permit liens on certain assets. Our ability to borrow funds within the terms of the unsecured Revolver is dependent upon our continued compliance with the financial and other covenants. At December 31, 2024, we had $1.2 billion of availability on the Revolver, $9.3 million of outstanding letters of credit and other obligations which reduce availability, and there were no borrowings outstanding.

The financial covenants under our Facility state that we must maintain an interest coverage ratio of not less than 2.50:1.00. Our interest coverage ratio is calculated by dividing our last-twelve-months (LTM) consolidated Adjusted EBITDA as defined in the Facility (earnings before interest, taxes, depreciation, amortization, and certain other non-cash transactions as defined in the Facility) by our LTM gross interest expense, less amortization of financing fees. In addition, a debt to capitalization ratio of not more than 0.60:1.00 must be maintained. At December 31, 2024, our interest coverage ratio and debt to capitalization ratio were 21.68:1.00 and 0.27:1.00, respectively. We were, therefore, in compliance with these covenants at December 31, 2024, and we anticipate we will continue to be in compliance during the next twelve months.

Working Capital (representing excess of current assets over current liabilities). We generated cash flow from operations of $1.8 billion in 2024 compared to $3.5 billion in 2023. Working capital decreased $1.2 billion, or 26%, during 2024 to $3.3 billion at December 31, 2024, due primarily to a $1.4 billion decrease in cash and equivalents and short-term investments in support of our capital investments within our aluminum and steel operations.

Table of Contents

Capital Investments. During 2024, we invested $1.9 billion in property, plant and equipment, primarily within our aluminum operations and steel operations segments, compared with $1.7 billion invested during 2023. We are currently executing our plan to invest $2.7 billion in a new state-of-the-art lower-carbon recycled aluminum flat rolled products mill with two new supporting satellite recycled aluminum slab centers, which are being funded by available cash and cash flow from operations. Related expenditures began in the third quarter of 2022 and are expected to continue through 2025. Our liquidity of $2.2 billion and anticipated future operating cash flow generation is sufficient to provide for our planned 2025 capital requirements.

Cash Dividends. As a reflection of continued confidence in our current and future cash flow generation capability and financial position, we increased our quarterly cash dividend by 8% to $0.46 per share in the first quarter of 2024 (from $0.425 per share for each quarter in 2023), resulting in declared cash dividends of $284.1 million during 2024, compared to $280.5 million in 2023. We paid cash dividends of $282.6 million and $271.3 million during 2024 and 2023, respectively. Our board of directors, along with executive management, approves the payment of dividends on a quarterly basis. The determination to pay cash dividends in the future is at the discretion of our board of directors, after taking into account various factors, including our financial condition, results of operations, outstanding indebtedness, current and anticipated cash needs and growth plans.

Other. Our board of directors has authorized share repurchase programs during prior years, the most recent of which occurred in November 2023 for a program of up to $1.5 billion of the company’s common stock. In February 2025, our board of directors authorized an additional share repurchase program of up to $1.5 billion of our common stock. Under the share repurchase programs, purchases take place as and when we determine in open market or private transactions made based upon the market price of our common stock, the nature of other investment opportunities or growth projects, our cash flows from operations, and general economic conditions. The share repurchase programs do not require us to acquire any specific number of shares, and may be modified, suspended, extended, or terminated by us at any time. The share repurchase programs do not have an expiration date. There were $1.2 billion and $1.5 billion of share repurchases during 2024 and 2023, respectively. As of December 31, 2024, we had $193.5 million remaining available to purchase under the November 2023 share repurchase program. See Part II, Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities for additional information.

Our ability to meet our debt service obligations and reduce our total debt will depend upon our future performance which, in turn, will depend upon general economic, financial, and business conditions, along with competition, legislation and regulatory factors that are largely beyond our control. In addition, we cannot assure that our operating results, cash flows, access to credit markets and capital resources will be sufficient for repayment of our indebtedness in the future. We believe that based upon current levels of operations and anticipated growth, cash flows from operations, together with other available sources of funds, including borrowings under our Facility, if necessary, will be adequate for the next twelve months for making required payments of principal and interest on our indebtedness, funding working capital requirements, and funding anticipated capital expenditures.

Contractual Obligations and Other Long-Term Liabilities

We have the following minimum commitments under contractual obligations, including purchase obligations, as defined by the Securities and Exchange Commission. A “purchase obligation” is defined as an agreement to purchase goods or services that is enforceable and legally binding and that specifies all significant terms, including fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transaction.

Long-term debt and estimated interest. Refer to Note 3. Long-Term Debt to the consolidated financial statements elsewhere in this report for our long-term debt maturities. Estimated interest payments on our senior unsecured notes were determined based on their outstanding balances through maturity at their contractual interest rates, as detailed in Note 3. Estimated interest payments also include a 0.175% commitment fee on our available Revolver, and an average interest rate of 6.23% on our other debt of $28.8 million. Our estimated interest payments are $116.4 million, $109.4 million, $89.0 million, $83.4 million, and $82.2 million, for the years 2025 through 2029, respectively, and $442.4 million thereafter.

Purchase obligations. We have commitments for the purchase of commodities such as electricity, water, natural gas and its transportation services, fuel, air products, zinc, and electrodes. Refer to Note 8. Commitments and Contingencies to the consolidated financial statements elsewhere in this report for this information.

Construction commitments. We have firm contracts with various vendors for the completion of certain construction projects at our various divisions at December 31, 2024. Refer to Note 8. Commitments and Contingencies to the consolidated financial statements elsewhere in this report for this information.

Lease commitments. We have entered into operating leases relating principally to transportation and other equipment, and some real estate. Refer to Note 11. Leases to the consolidated financial statements elsewhere in this report for this information.

Unrecognized tax benefits. We expect to make cash outlays in the future related to our unrecognized tax benefits; however, due to the uncertainty of the timing, we are unable to make reasonably reliable estimates regarding the period of cash settlement with the respective taxing authorities. Refer to Note 4. Income Taxes to the consolidated financial statements elsewhere in this report for this information.

Other Matters

Environmental and Other Contingencies

We have incurred, and in the future will continue to incur, capital expenditures and operating expenses for matters relating to environmental control, remediation, monitoring, and compliance. During 2024, we incurred costs related to the monitoring and compliance of environmental matters in the amount of approximately $60.2 million and capital expenditures related to environmental compliance of approximately $4.3 million. Of the costs incurred during 2024 for monitoring and compliance, approximately 74% were related to the normal transportation of certain types of by-products produced in our steelmaking processes and other facilities in accordance with legal requirements. We incurred combined environmental remediation costs of approximately $4.9 million at all of our facilities during 2024. We have an accrual of $3.8 million recorded for environmental remediation related to our metals recycling operations, $2.6 million related to our idled Minnesota ironmaking operations, and $712,000 related to our steel operations. We believe, apart from our dependence on environmental construction and operating permits for our existing and any future manufacturing facilities, that compliance with current environmental laws and regulations is not likely to have a materially adverse effect on our financial condition, results of operations, or liquidity. However, environmental laws and regulations evolve and change, and we may become subject to more stringent environmental laws and regulations in the future, such as the impact of various governmental legislatures and agencies introducing regulatory changes in response to the potential of climate change.

Critical Accounting Estimates

Management’s Discussion and Analysis of Our Financial Condition and Results of Operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. We review the accounting estimates we use in reporting our financial results on a regular basis. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent liabilities. We evaluate the appropriateness of these estimations and judgments on an ongoing basis. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Results may differ from these estimates due to actual outcomes being different from those on which we based our assumptions. We believe the following critical accounting estimates affect our more significant judgments and estimates used in the preparation of our consolidated financial statements.

Table of Contents

Impairments of Long-Lived Tangible and Definite-Lived Intangible Assets. We review long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be fully recoverable. Impairment losses are recorded on long-lived assets used in operations when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amounts. The impairment loss is measured by comparing the fair value of the asset to its carrying amount. We consider various factors and determine whether an impairment test is necessary, including by way of examples, a significant and prolonged deterioration in operating results and/or projected cash flows, significant changes in the extent or manner in which an asset is used, technological advances with respect to assets which would potentially render them obsolete, our strategy and capital planning, and the economic environment in markets to be served. When determining future cash flows, and, if necessary, fair value, we must make judgments as to the expected utilization of assets and estimated future cash flows related to those assets. We consider historical and anticipated future results, general economic and market conditions, the impact of planned business and operational strategies, and all other available information at the time the estimates are made. Those estimates and judgments may or may not ultimately prove accurate. There were no indicators of impairment or impairment charges recorded during 2024, 2023, or 2022.

Goodwill.

Our goodwill, relating to various business combinations, consisted of the following at December 31, 2024 and 2023 (in thousands):



Steel Operations Segment	$	272,133
Aluminum Operations Segment		14,000
Metals Recycling Operations Segment		189,413
Steel Fabrication Operations Segment		1,925
	$	477,471

At least once annually (as of October 1), or when indicators of impairment exist, we perform a goodwill impairment analysis. Goodwill is allocated to various reporting units, which are generally one level below the company’s operating segments. If the fair value exceeds the carrying value of the reporting unit, there is no impairment. If the carrying amount exceeds the fair value, we recognize an impairment loss in the amount by which the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, with the impairment loss not to exceed the amount of goodwill allocated to the reporting unit. We have the option to consider qualitative factors to assess if it is more likely than not that the fair value of a reporting unit exceeds its carrying value. If we elect to bypass the qualitative assessment or if indications of a potential impairment exist, we perform a quantitative test.

When conducting a qualitative assessment, we consider the impact of several factors on the company overall and each reporting unit individually including the timing and results of prior quantitative tests performed, changes in the carrying amount of the reporting unit, macroeconomic conditions (including changes in interest and discount rates), industry and market conditions, recent and projected financial performance, the company’s competitive position and other factors. Significant judgment is involved in evaluating the totality of all factors to determine whether it is more likely than not that the fair value of the reporting unit exceeds its carrying value.

When conducting a quantitative test, the fair value of the reporting unit is determined by using an estimate of future cash flows utilizing a risk-adjusted discount rate to calculate the net present value of future cash flows (income approach), and for some years by using a market approach based upon an analysis of valuation metrics of comparable peer companies, using Level 3 fair value inputs as provided for under ASC 820. Key assumptions used to determine the estimated fair value of each reporting unit under the discounted cash flows method (income approach) include: (a) expected cash flows for the five-year period following the testing date (including market share, sales volumes and prices, costs to produce and estimated capital needs); (b) an estimated terminal value using a terminal year growth rate determined based on the growth prospects of the reporting unit; and (c) a risk-adjusted discount rate based on management’s best estimate of market participants’ after-tax weighted average cost of capital and market risk premiums. Key assumptions used to determine the estimated fair value of each reporting unit under the market approach include the expected revenues and cash flows in the next year. We consider historical and anticipated future results, general

Table of Contents

economic and market conditions, the impact of planned business and operational strategies and all available information at the time the fair values of reporting units are estimated. Those estimates and judgments may or may not ultimately prove accurate.

Goodwill acquired in past transactions is naturally more susceptible to impairment, primarily due to the fact that they are recorded at fair value based on operating plans and economic conditions at the time of acquisition. Consequently, if operating results and/or economic conditions deteriorate after an acquisition, it could result in the impairment of the acquired asset. A deterioration of economic conditions may not only negatively impact the estimated operating cash flows used in our cash flow models but may also negatively impact other assumptions used in our analyses, including, but not limited to, the estimated cost of capital and/or discount rates. Additionally, we are required to ensure that assumptions used to determine fair value in our analyses are consistent with the assumptions a hypothetical marketplace participant would use. As a result, the cost of capital and/or discount rates used in our analyses may increase or decrease based on market conditions and trends, regardless of whether our actual cost of capital has changed. Therefore, we may recognize an impairment in spite of realizing actual cash flows that are approximately equal to or greater than our previously forecasted amounts. Accordingly, our qualitative assessments consider changes in interest rates and our quantitative tests include discount rate scenario analysis to evaluate the impact on estimated reporting unit fair values.

Our fourth quarter 2024, 2023, and 2022 annual goodwill impairment analyses did not result in any impairment charges. During 2024, we performed a qualitative assessment and performed quantitative tests in 2023 and 2022. Management does not believe that it is reasonably likely that our reporting units will fail the goodwill impairment test in the near term, given the results of our most recent qualitative assessment and the determined fair value of the reporting units with goodwill from our most recent quantitative test exceeded their carrying value by more than an insignificant amount. Changes in judgments and estimates underlying our analysis of goodwill for possible impairment, including expected future operating cash flows and discount rate, could decrease the estimated fair value of our reporting units in the future and could result in an impairment of goodwill.

Income Taxes. We are required to estimate our income taxes as a part of the process of preparing our consolidated financial statements. This requires us to estimate our actual current tax exposure together with assessing temporary differences resulting from differing treatments of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheet. We must then assess the likelihood that our deferred tax assets will be recovered from future taxable income and, to the extent we believe that recovery is not likely, we must establish a valuation allowance. We also establish reserves to reduce some or all of the tax benefit of any of our tax positions at the time we determine that the positions become uncertain. We adjust these reserves, including any impact on the related interest and penalties, in light of changing facts and circumstances, such as the progress of a tax audit. A number of years may elapse before a particular matter for which we have established a reserve is audited by a taxing authority and finally resolved. The number of years with open tax audits varies depending on the tax jurisdiction. A tax benefit that has been previously reserved because of a failure to meet the "more likely than not" recognition threshold would be recognized in our income tax expense in the first interim period when the uncertainty disappears. Settlement of any particular issue would usually require the use of cash.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk

In the normal course of business, we are exposed to interest rate changes. Our objectives in managing fluctuations in interest rates are to limit the impact of these rate changes on earnings and cash flows and to lower overall borrowing costs.

The following table represents the principal cash repayments and related weighted-average interest rates by maturity date for our long-term debt, as of December 31, 2024 (in thousands):



	Interest Rate Risk
	Fixed Rate				Variable Rate
			Average				Average
	Principal		Rate		Principal		Rate
Expected maturity date:
2025	$	401,071		2.4%	$	26,371		6.4%
2026		400,896		5.0		-
2027		350,465		1.7		-

Total debt outstanding	$	3,252,432		3.6%	$	26,371		6.4%
Fair value	$	2,987,850			$	26,371

Commodity Risk

In the normal course of business, we are exposed to the market risk and price fluctuations related to the sale of our products and to the purchase of raw materials used in our operations, such as metallic raw materials, electricity, water, natural gas and its transportation services, fuel, air products, zinc, and electrodes. Our risk strategy associated with product sales has generally been to obtain competitive prices for our products and to allow operating results to reflect market price movements dictated by supply and demand.

Our risk strategy associated with the purchase of raw materials utilized within our operations has generally been to make some commitments with suppliers relating to future expected requirements for some commodities such as electricity, water, natural gas and its transportation services, fuel, air products, zinc, and electrodes. Refer to Note 8. Commitments and Contingencies to the consolidated financial statements elsewhere in this report for additional information.

In our metals recycling, aluminum, and steel operations, we have certain fixed price contracts with various customers and suppliers for future delivery of nonferrous and ferrous metals. Our risk strategy has been to enter into base metal financial contracts with the goal to protect the profit margin, within certain parameters, that was contemplated when we entered into the transaction with the customer or vendor. At December 31, 2024, we had a cumulative unrealized gain associated with these financial contracts of $13.1 million, substantially all of which have settlement dates in 2025. We believe the customer contracts associated with the financial contracts will be fully consummated.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Steel Dynamics, Inc. is responsible for the preparation and integrity of the company’s consolidated financial statements and for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a – 15(f) of the Exchange Act, for the company (including its consolidated subsidiaries). We maintain accounting and internal control systems which are intended to provide reasonable assurance that assets are safeguarded against loss from unauthorized use or disposition, transactions are executed in accordance with management’s authorization, and accounting records are reliable for preparing financial statements in accordance with accounting principles generally accepted in the United States. We are dedicated to ensuring that we maintain the high standards of financial accounting and reporting that we have established. Our culture demands integrity and an unyielding commitment to strong internal control practices and policies.

Internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of the financial statements in accordance with generally accepted accounting principles; and provide reasonable assurance that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.

Because of its inherent limitations, internal control over financial reporting may not always prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies and procedures may deteriorate.

Under the supervision and with the participation of our management, including our principal executive officer and our principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting. The framework on which such evaluation was based upon is contained in the report entitled “Internal Control—Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) (the “COSO criteria”). Based on that evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2024, the end of the period covered by this report.

	Valuation of Goodwill
Description of the Matter	At December 31, 2024, the Company’s goodwill was approximately $477 million. As discussed in Note 1 of the consolidated financial statements, the Company performs an impairment test for goodwill at least annually or when indicators of impairment exist. The Company performed a qualitative assessment as of October 1, 2024, to assess if it is more likely than not that the fair value of a reporting unit exceeds its carrying amount.
		Auditing management’s annual goodwill impairment test was complex and judgmental as management considers the impact of several factors on the Company overall and each reporting unit individually including assessing the qualitative factors to be considered in the qualitative goodwill impairment assessment, changes in the carrying amount of the reporting unit, macroeconomic conditions (including changes in interest and discount rates), industry and market conditions, recent and projected financial performance, the Company’s competitive position and other factors. Significant judgment is involved in evaluating the totality of all factors to determine whether it is more likely than not that the fair value of the reporting unit exceeds its carrying value.
How We Addressed the Matter in Our Audit	We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company’s goodwill impairment testing process, including controls over management’s review of the qualitative factors described above.
		To test management’s conclusion that it is more likely than not that the fair values of the Company’s reporting units exceed their carrying amounts, we performed audit procedures that included, among others, assessing the reasonableness of the qualitative factors considered within the analyses, testing the evaluation of the qualitative factors and the underlying data used by the Company in its analyses. We evaluated management’s assessment of the qualitative factors for each reporting unit by comparing to current industry and economic trends, current and historical results and key business drivers for each reporting unit, comparing the Company’s share price trends to historical amounts, and other relevant factors, including considering consistency with evidence obtained in other parts of the audit and evaluating whether any contrary evidence exists.

Note 1. Description of the Business and Summary of Significant Accounting Policies

Description of the Business

Steel Dynamics, Inc. (SDI), together with its subsidiaries (the company), is one of the largest and most diversified domestic steel producers and metals recycler, combined with a meaningful steel fabrication manufacturing platform. The company has four reporting segments: steel operations, metals recycling operations, steel fabrication operations, and aluminum operations. Effective the fourth quarter 2024, results from an entity previously reported within the metals recycling operations segment were moved to the aluminum operations segment, consistent with a change in how the company’s chief operating decision maker manages the business. Segment information provided within this Form 10-K, including that within Note 12. Segment Information, has been recast for all prior periods consistent with the current reportable segment presentation. Approximately 5% of the company’s workforce in four locations is represented by collective bargaining agreements, and agreements affecting 0.5% of the company’s employees at one location expires during 2025.

Steel Operations Segment

Steel operations include the company’s electric arc furnace (EAF) steel mills, including Butler Flat Roll Division, Columbus Flat Roll Division, Southwest-Sinton Flat Roll Division, Structural and Rail Division, Engineered Bar Products Division, Roanoke Bar Division, and Steel of West Virginia, steel coating and processing operations at The Techs, Heartland Flat Roll Division, United Steel Supply (USS) – 90% equity interest as of April 1, 2023, Vulcan Threaded Products, warehouse operations in Mexico, and SDI Biocarbon Solutions, a joint venture to construct and operate a biocarbon production facility, of which SDI has a 75% equity interest.

Metals Recycling Operations Segment

Metals recycling operations include the company’s OmniSource ferrous and nonferrous processing, transportation, marketing, brokerage, and scrap management services primarily throughout the United States and in Central and Northern Mexico.

Steel Fabrication Operations Segment

Steel fabrication operations include the company’s New Millennium Building Systems joist and deck plants located throughout the United States, and in Northern Mexico. Revenues from these plants are generated from the fabrication of girders, steel joists and steel deck used within the non-residential construction industry.

Aluminum Operations Segment

Aluminum operations include the recycled aluminum flat rolled products mill nearing completion of construction in Columbus, Mississippi, two satellite recycled aluminum slab centers in the southwest United States and Central Mexico, and an entity with aluminum operations, formerly included in the results of the metals recycling operations segment. The flat rolled products mill is a joint venture with Unity Aluminum, Inc. of which SDI has a 94.4% equity interest. The aluminum flat rolled products mill and the Mexico and US recycled aluminum slab centers are expected to begin operations in mid to late 2025.

Other

Other operations consist of subsidiary operations that are below the quantitative thresholds required for reportable segments and primarily consist of joint ventures and the company’s idled Minnesota ironmaking operations. Also included in “Other” are certain unallocated corporate accounts, such as the company’s senior unsecured credit facility, senior notes, certain other investments, and certain profit sharing expenses.

Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of SDI, together with its wholly- and majority-owned or controlled subsidiaries, after elimination of intercompany accounts and transactions. Noncontrolling and redeemable noncontrolling interests represent the noncontrolling owners' proportionate share in the equity, income, or losses of the company’s majority-owned or controlled consolidated subsidiaries. Redeemable noncontrolling interests related to USS (owned 90% by SDI) are $60.0 million at December 31, 2024 and 2023. Redeemable noncontrolling interests related to Mesabi Nugget (owned 86% by SDI) are $111.2 million at December 31, 2024 and 2023.

Use of Estimates

These consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States, and accordingly, include amounts that require management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and in the notes thereto. Significant items subject to such estimates and assumptions include the carrying value of property, plant and equipment, intangible assets, and goodwill; allowances for credit losses for trade receivables, inventories and deferred income tax assets; unrecognized tax benefits; potential environmental liabilities; and litigation claims and settlements. Actual results may differ from these estimates and assumptions.

Revenue from Contracts with Customers

In the steel, metals recycling, and aluminum operations segments, revenue is recognized at the point in time the performance obligation is satisfied, and control of the product is transferred to the customer upon shipment or delivery, at the amount of consideration the company expects to receive, including any variable consideration. The variable consideration included in the company’s steel operations segment contracts, which is not constrained, includes estimated product returns and customer claims based on historical experience, and may include volume rebates which are recorded on an expected value basis. Revenue recognized is limited to the amount the company expects to receive. The company does not exercise significant judgments in determining the timing of satisfaction of performance obligations or the transaction price. Shipment of products to customers is considered a fulfillment activity with amounts billed to customers included in sales and costs associated with such activities included in cost of goods sold.

The company’s steel fabrication operations segment recognizes revenue over time at the amount of consideration the company expects to receive. Revenue is measured on an output method representing completed fabricated tons to date as a percentage of total tons required for each contract. Revenue from fabrication of tons remaining on partially fabricated customer contracts as of a reporting date, and future revenue from yet to be fabricated customer contracts, has not been disclosed under the practical expedient in Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers (ASC 606), paragraph ASC 606-10-50-14 related to customer contracts with expected duration of one year or less. The company does not exercise significant judgments in determining the timing of satisfaction of performance obligations or the transaction price. Shipment of products to customers, which occurs after control over the product has transferred to the customer and revenue is recognized, is considered a fulfillment activity with amounts billed to customers included in sales and costs associated with such activities included in cost of goods sold.

Payments from customers are generally due within 30 days of invoicing, which generally occurs upon shipment of the products. Shipment for the steel fabrication operations segment generally occurs within 30 days of satisfaction of the performance obligation and revenue recognition. The company does not have financing components. Payments from customers have historically been within these terms, however, payments for non-U.S. sales may extend longer.

Refer to Note 12. Segment Information for disaggregated revenue by segment to external, external non-United States, and other segment customers.

Credit Losses

The company is exposed to credit risk in the event of nonpayment of accounts receivable by customers. The company mitigates its exposure to credit risk, which it generally extends on an unsecured basis, by performing ongoing credit evaluations and taking further action if necessary, such as requiring letters of credit or other security interests to support the customer receivable. The allowance for credit losses for accounts receivable is based on the company’s reasonable estimate of known credit risks and historical experience, adjusted for current and anticipated economic and other pertinent factors affecting the company’s customers, that may differ from historical experience. Customer accounts receivable are written off when all collection efforts have been exhausted and the amounts are deemed uncollectible.

At December 31, 2024 and 2023, the company reported $1,417.2 million and $1,608.3 million, respectively, of accounts receivable, net of allowances for credit losses of $7.7 million and $8.5 million, respectively. Changes in the allowance were not significant for the years ended December 31, 2024, 2023, or 2022.

Cash and Equivalents, and Restricted Cash

Cash and equivalents include all highly liquid investments with a maturity of three months or less at the date of acquisition. Restricted cash is primarily funds held in escrow as required by various insurance and government organizations. The balance of cash, cash equivalents and restricted cash in the consolidated statements of cash flows includes restricted cash of $5.5 million at December 31, 2024, $5.6 million at December 31, 2023, and $5.5 million at December 31, 2022, and 2021, which is recorded in Other Assets (noncurrent) in the company’s consolidated balance sheets.

Short-Term Investments

Short-term investments include investments with maturity dates of longer than three months but less than one year when purchased. The company’s short-term investments are classified as trading securities. The short-term investments held as of December 31, 2024 consisted of commercial paper ($19.7 million), US Treasuries ($113.1 million), and certificates of deposit ($15.0 million). Short-term investments held as of December 31, 2023 consisted of commercial paper ($146.2 million), US Treasuries ($564.9 million), and certificates of deposit ($10.1 million). Interest income from invested cash and short-term investments was $90.1 million, $111.9 million, and $29.3 million for the years ended December 31, 2024, 2023, and 2022, respectively, and is recorded in other (income) expense, net as earned.

Inventories

Inventories are stated at lower of cost or net realizable value. Cost is determined using a weighted average cost method for raw materials (including scrap and purchased steel substrate) and supplies, and on a first-in, first-out basis for other inventory. Inventory consisted of the following at December 31 (in thousands):


	2024		2023
Raw materials	$	1,323,920	$	1,226,272

Total inventories	$	3,113,733	$	2,894,632

Table of Contents

Note 1. Description of the Business and Summary of Significant Accounting Policies (Continued)

Property, Plant and Equipment

Property, plant and equipment are stated at cost which includes capitalized interest on construction in progress amounts, and is reduced by proceeds received from certain state and local government grants and other capital cost reimbursements, except for assets acquired in acquisitions which are valued at fair value at the purchase date. The company assigns each fixed asset a useful life ranging from 3 to 15 years for plant, machinery and equipment, and 5 to 40 years for buildings and improvements. Repairs and maintenance are expensed as incurred. Depreciation is provided utilizing the straight-line depreciation methodology, or the units-of-production depreciation methodology for certain production-related steel operations segment assets, based on units produced, subject to minimum and maximum levels. Depreciation expense was $441.2 million, $397.0 million, and $349.4 million for the years ended December 31, 2024, 2023, and 2022, respectively.

The company’s property, plant and equipment consisted of the following at December 31 (in thousands):


	2024		2023
Land and improvements	$	801,210	$	693,166
Buildings and improvements		1,487,742		1,255,274

Intangible Assets

The company’s intangible assets consisted of the following at December 31 (in thousands):


						Weighted

Less accumulated amortization		365,528		335,603
	$	227,234	$	257,759

The company utilizes an accelerated amortization methodology for customer, vendor and scrap generator relationships in order to follow the pattern in which the economic benefits of the amounts are anticipated to be consumed. Trade names are amortized using a straight-line methodology. Amortization of intangible assets was $30.5 million, $34.0 million, and $27.8 million for the years ended December 31, 2024, 2023, and 2022, respectively.

Impairment of Long-Lived Tangible and Definite-Lived Intangible Assets

The company reviews long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be fully recoverable. Impairment losses are recorded on long-lived assets used in operations when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amounts. The impairment loss is measured by comparing the fair value of the assets to its carrying amount. The company considers various factors and determines whether an impairment test is necessary, including by way of examples, a significant and prolonged deterioration in operating results and/or projected cash flows, significant changes in the extent or manner in which an asset is used, technological advances with respect to assets which would potentially render them obsolete, the company’s strategy and capital planning, and the economic environment in markets to be served.

Goodwill

The company’s goodwill consisted of the following at December 31, 2024 and 2023 (in thousands):



Steel Operations Segment	$	272,133
Aluminum Operations Segment		14,000
Metals Recycling Operations Segment		189,413
Steel Fabrication Operations Segment		1,925
	$	477,471

In the fourth quarter 2024, results from an entity previously included in the metals recycling operations segment were moved to the aluminum operations segment, which also resulted in $14 million of goodwill being reassigned to the aluminum operations segment based on a relative fair value allocation approach. Segment information for 2023 has been recast consistent with the current reportable segment presentation. Cumulative OmniSource goodwill impairment charges were $346.8 million at December 31, 2024 and 2023.

Impairment of Goodwill

At least once annually (as of October 1), or when indicators of impairment exist, the company performs a goodwill impairment analysis. Goodwill is allocated to various reporting units, which are generally one level below the company’s operating segments. If the fair value exceeds the carrying value of the reporting unit, there is no impairment. If the carrying amount exceeds the fair value, the company recognizes an impairment loss in the amount by which the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, with the impairment loss not to exceed the amount of goodwill allocated to the reporting unit. The company has the option to consider qualitative factors to assess if it is more likely than not that the fair value of a reporting unit exceeds its carrying value. If elected to bypass the qualitative assessment or if indications of a potential impairment exist, the company performs a quantitative test.

Table of Contents

Note 1. Description of the Business and Summary of Significant Accounting Policies (Continued)

When conducting a qualitative assessment, the company considers the impact of several factors on the company overall and each reporting unit individually including the timing and results of prior quantitative tests performed, changes in the carrying amount of the reporting unit, macroeconomic conditions (including changes in interest and discount rates), industry and market conditions, recent and projected financial performance, the company’s competitive position and other factors. When conducting a quantitative test, the fair value of the reporting unit is determined by using an estimate of future cash flows utilizing a risk-adjusted discount rate to calculate the net present value of future cash flows (income approach), and for some years by using a market approach based upon an analysis of valuation metrics of comparable peer companies, using Level 3 fair value inputs as provided for under ASC 820, Fair Value Measurement.

No impairment was identified during the company’s 2024, 2023 or 2022 annual goodwill impairment analysis. During 2024, the company performed a qualitative assessment and performed quantitative tests in 2023 and 2022.

Equity-Based Compensation

The company has several stock-based employee compensation plans which are more fully described in Note 6. Equity-Based Incentive Plans. Compensation expense for restricted stock units, deferred stock units, restricted stock, stock appreciation awards, and performance awards is recorded over the vesting periods using the fair value as determined by the closing fair market value of the company’s common stock on the grant date, and with respect to performance awards, an estimate of probability of award achievement during the performance period. The company recognizes forfeitures as they occur. Compensation expense for these stock-based employee compensation plans was $65.6 million, $60.1 million, and $69.2 million for the years ended December 31, 2024, 2023, and 2022, respectively.

Income Taxes

The company accounts for income taxes and the related accounts under the liability method. Deferred tax liabilities and assets are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted rates expected to be in effect during the year in which the basis differences reverse.

Earnings Per Share

Basic earnings per share is based on the weighted average shares of common stock outstanding during the period. Diluted earnings per share assumes the weighted average dilutive effect of common share equivalents outstanding during the period applied to the company’s basic earnings per share. Common share equivalents represent potentially dilutive restricted stock units, deferred stock units, restricted stock, and performance awards, and are excluded from the computation in periods in which they have an anti-dilutive effect. There were 269,000 anti-dilutive common stock equivalents as of and for the year ended December 31, 2024. There were no anti-dilutive common stock equivalents as of and for the years ended December 31, 2023, and 2022.

Concentration of Credit Risk

Financial instruments that potentially subject the company to significant concentrations of credit risk principally consist of temporary cash investments and accounts receivable. When advantageous, the company places its temporary cash with high credit quality financial institutions and companies and limits the amount of credit exposure from any one entity. The company is exposed to credit risk in the event of nonpayment by customers. The company mitigates its exposure to credit risk, which it generally extends initially on an unsecured basis, by performing ongoing credit evaluations and taking further action if necessary, such as requiring letters of credit or other security interests to support the customer receivable.

Derivative Financial Instruments

The company routinely enters into forward exchange traded futures to manage price risk associated with nonferrous metal inventory, as well as purchases and sales of nonferrous (primarily aluminum and copper) and ferrous metals, to reduce exposure to commodity related price fluctuations. The company does not enter into these derivative financial instruments for speculative purposes. The company recognizes all derivatives as either assets or liabilities in the consolidated balance sheets and measures those instruments at fair value. Derivatives that are not designated as hedges must be adjusted to fair value through earnings. Changes in the fair value of derivatives that are designated as hedges, depending on the nature of the hedge, are recognized as either an offset against the change in fair value of the hedged balance sheet item in the case of fair value hedges or as other comprehensive income in the case of cash flow hedges, until the hedged item is recognized in earnings. The ineffective portion of a derivative’s change in fair value is immediately recognized in earnings for fair value hedges. The company offsets fair value amounts recognized for derivative instruments executed with the same counterparty under master netting agreements.

In the normal course of business, the company has derivative financial instruments in the form of forward contracts in various metallic commodities and those related to managing fluctuations in foreign exchange rates. At the time of acquiring these financial instruments, the company designates and assigns these instruments as hedges of specific assets, liabilities or anticipated transactions. When hedged assets or liabilities are sold or extinguished, or the anticipated transaction being hedged is no longer expected to occur, the company recognizes the gain or loss on the designated hedged financial instrument in earnings.

Table of Contents

Note 1. Description of the Business and Summary of Significant Accounting Policies (Continued)

The fair value of the Company’s derivative instruments, along with required margin deposit amounts with the same counterparty under master netting arrangements, totaled $26.0 million and $24.0 million at December 31, 2024 and 2023, respectively, and are reflected in other current assets in the consolidated balance sheets. Total gains and losses related to derivatives in fair value hedging relationships, as well as those not designated as hedging instruments, are recognized in costs of goods sold and were insignificant for the years ended December 31, 2024, 2023, and 2022. Derivatives accounted for as cash flow hedges, for which gains and losses are recognized in other comprehensive income, along with net amounts reclassified from accumulated other comprehensive income, were insignificant for the years ended December 31, 2024, 2023, and 2022.

Recently Adopted Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The company adopted ASU 2023-07 during the year ended December 31, 2024. See Note 12. Segment Information.

Recently Issued Not Yet Adopted Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which modifies the rules on income tax disclosures to require entities to disclose specific categories in the rate reconciliation, the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and income tax expense or benefit from continuing operations (separated by federal, state and foreign). ASU 2023-09 also requires entities to disclose their income tax payments to international, federal, state, and local jurisdictions, among other changes. The guidance is effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. ASU 2023-09 is to be applied on a prospective basis, but retrospective application is permitted. The company is currently evaluating the impact of adopting ASU 2023-09.

In November 2024, the FASB issued ASU 2024-03, Income Statement Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, requiring public entitles to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2024-03.

Note 2. Business Combinations and Investments in Unconsolidated Affiliates

Business Combinations

ROCA

The company acquired 100% of ROCA ACERO, S.A. de C.V. (ROCA) on October 1, 2022. The acquisition of ROCA is part of the company’s North American raw material procurement strategy. ROCA is headquartered in Monterrey, Mexico, and operates ferrous and nonferrous scrap facilities strategically positioned near high-volume industrial scrap sources located throughout Central and Northern Mexico. The transaction was funded with available cash. Post-acquisition operating results are reflected in the company’s financial statements in the metals recycling operations segment.

Aluminum Dynamics

The company obtained a 94.4% equity interest in a joint venture concurrently formed with Unity Aluminum, Inc. on July 29, 2022, for the construction and operation of a new state-of-the-art lower-carbon recycled aluminum flat rolled products mill. The transaction was funded with available cash. Operating results from and after July 29, 2022, are reflected in the company’s consolidated financial statements in the aluminum operations segment.

United Steel Supply

The company purchased a 75% equity interest in United Steel Supply, LLC on March 1, 2019. On April 1, 2022, the company purchased an additional 12.5% equity interest in USS. On April 1, 2023, a noncontrolling member of USS exercised its option to require SDI to purchase its 2.5% equity interest, increasing SDI’s ownership to 90%. The remaining noncontrolling members have the option to require SDI to purchase the remaining 10% equity interest of USS on or after February 28, 2025. The USS noncontrolling interest is therefore reflected in redeemable noncontrolling interest in the consolidated balance sheets.

Investments in Unconsolidated Affiliates

The company purchased a 45% minority equity interest in New Process Steel, L.P. (NPS) on January 31, 2022. NPS is a metals solutions and distribution supply-chain management company headquartered in Houston, Texas, with a focus toward growing its value-added manufacturing applications. On February 28, 2022, the company also purchased a minority equity interest in Aymium, a producer of renewable biocarbon products. As the company does not have power to control these entities, the company accounts for these investments using the equity method of accounting, which are recorded in Other Assets (noncurrent) in the company’s consolidated balance sheets with related activity recorded in Other (Income) Expense, net. Profits or losses from transactions with NPS are eliminated until realized by the majority equity interest owner.

Note 3. Long-Term Debt (Continued)

Senior Credit Facility, due 2028

On July 19, 2023, the company entered into an unsecured credit agreement comprised of a senior unsecured credit facility (Facility), which provides a $1.2 billion unsecured Revolver, maturing July 2028. Subject to certain conditions, the company has the opportunity to increase the Facility size by $500.0 million. The unsecured Facility is available to fund working capital, capital expenditures, and other general corporate purposes. The Facility contains financial covenants and other covenants pertaining to the company’s ability to incur indebtedness and permit liens on certain assets. The company’s ability to borrow funds within the terms of the unsecured Facility is dependent upon its continued compliance with financial and other covenants. At December 31, 2024, the company had $1.2 billion of availability on the Facility, $9.3 million of outstanding letters of credit and other obligations which reduce availability, and there were no borrowings outstanding.

The Facility pricing grid is adjusted quarterly and is based on either the company’s leverage of net debt (as defined in the Facility) to last-twelve-months (LTM) consolidated Adjusted EBITDA as defined in the Facility (earnings before interest, taxes, depreciation, amortization, and certain other non-cash items as allowed in the Facility), or the company’s credit ratings. The minimum pricing is adjusted Secured Overnight Financing Rate (SOFR) plus 1.000% and the maximum pricing is adjusted SOFR plus 1.75%. In addition, the company is subject to an unused commitment fee of between 0.11% and 0.275% (based on either the leverage of net debt to LTM consolidated adjusted EBITDA, or the company’s credit ratings) which is applied to the unused portion of the Facility.

The financial covenants under the Facility state that the company must maintain an interest coverage ratio of not less than 2.50:1.00. The company’s interest coverage ratio is calculated by dividing its LTM consolidated Adjusted EBITDA by its LTM gross interest expense, less amortization of financing fees. In addition, a debt to capitalization ratio of not more than 0.60:1.00 must be maintained. At December 31, 2024, the company’s interest coverage ratio and debt to capitalization ratio were 21.68:1.00 and 0.27:1.00, respectively. The company was, therefore, in compliance with these covenants at December 31, 2024, and anticipates remaining in compliance during the next twelve months.

Certain wholly-owned and controlled subsidiaries of the company file separate federal and state income tax returns. One of the controlled subsidiaries generated federal net operating loss carryforwards in the years 2018 and prior, which were fully utilized as of December 31, 2024, but continues to have state net operating loss carryforwards which expire in the years 2034 through 2039. Annually, the company evaluates the realizability of the net deferred tax assets for this controlled subsidiary. In completing this evaluation, the company considers all available positive and negative evidence in order to determine whether, based on the weight of the evidence, a valuation allowance for its deferred tax assets is necessary. Such evidence includes current operating results, historical results, future reversals of existing taxable temporary differences and expectations for future taxable income (exclusive of the reversal of temporary differences and carryforwards), as well as the implementation of feasible and prudent tax planning strategies. Based on the evidence, the company maintained a valuation allowance of $1,150,000 and $816,000 as of December 31, 2024, and 2023, respectively, with respect to certain state tax credits of the controlled subsidiary.

Included in the balance of unrecognized tax benefits at December 31, 2024 and 2023 are potential benefits of $26.4 million and $27.8 million, respectively, that, if recognized, would affect the effective tax rate. The company recognizes interest and penalties related to its tax contingencies on a net-of-tax basis in income tax expense. During the years ended December 31, 2024, 2023, and 2022, the company recognized expense from the increase of interest expense and penalties of $710,000, $1,560,000, and $480,000, respectively, net of tax. In addition to the unrecognized tax benefits in the table above, the company had $4.2 million and $3.2 million accrued for the payment of interest and penalties at December 31, 2024 and 2023, respectively.

Note 4. Income Taxes (Continued)

It is reasonably possible that the amount of unrecognized tax benefits could change in the next twelve months in an amount ranging from zero to $12.0 million, as a result of the expiration of the statute of limitations and other federal and state income tax audits. The company files income tax returns in the U.S. federal jurisdiction as well as income tax returns in various state jurisdictions. The tax years 2021 through 2023 remain open to examination by the Internal Revenue Service and various state and local jurisdictions.

Treasury Stock

In July 2021, the board of directors authorized a share repurchase program of up to $1.0 billion of the company’s common stock. This program was exhausted in April 2022. In February 2022, the board of directors authorized an additional share repurchase program of up to $1.25 billion of the company’s common stock. This program was exhausted in November 2022. In November 2022, the board of directors authorized an additional share repurchase program of up to $1.5 billion of the company’s common stock. This program was exhausted in November 2023. In November 2023, the board of directors authorized an additional share repurchase program of up to $1.5 billion of the company’s common stock. Subsequent to December 31, 2024, in February 2025, the board of directors authorized an additional share repurchase program of up to $1.5 billion of the company’s common stock. Under the share repurchase programs, purchases take place as and when we determine in open market or private transactions made based upon the market price of our common stock, the nature of other investment opportunities or growth projects, our cash flows from operations, and general economic conditions. The share repurchase programs do not require us to acquire any specific number of shares, and may be modified, suspended, extended, or terminated by us at any time. The share repurchase programs do not have an expiration date. The company repurchased 9.4 million shares for $1.2 billion during 2024, 13.4 million shares for $1.5 billion during 2023, and 23.0 million shares for $1.8 billion during 2022 under the share repurchase programs. At December 31, 2024, the company had remaining authorization to repurchase $193.5 million of additional shares under the November 2023 share repurchase program.

Note 6. Equity-Based Incentive Plans

2023 Equity Incentive Plan

In May 2023, the company’s shareholders approved the 2023 Equity Incentive Plan (2023 Plan), which supersedes the prior Amended and Restated 2015 Equity Incentive Plan. The 2023 Plan is designed to attract, motivate, and retain qualified persons that are able to make important contributions to the company’s success. To accomplish these objectives, the 2023 Plan provides for awards of equity-based incentives through granting of restricted stock units (RSUs), deferred stock units (DSUs), stock appreciation rights (SARs), performance awards, such as the long-term incentive compensation program (LTIP), restricted stock awards (of which none have been granted), stock options (of which none have been granted), and unrestricted stock awards (of which none have been granted). Under the 2023 Plan, 9.0 million shares of common stock were reserved for grant through December 31, 2033. The 2023 Plan uses a fungible share concept under which any awards that are not a full-value award, such as stock options and stock-settled SARs, will be counted against the share reserve as one share for each share of common stock, and awards that are full-value awards, such as RSUs, DSUs, restricted and unrestricted stock awards, and performance awards, will be counted against the share reserve as 2.09 shares for each share of common stock. The SARs the company has granted to date can only be settled in cash, and thus, do not count against the share reserve. At December 31, 2024, there were 6.2 million shares still available for issuance.

Note 6. Equity-Based Incentive Plans (Continued)

Substantially all of the company’s full-time, non-union, U.S. team members receive RSUs, which are granted annually in November at no cost to employees and vest 100% over the shorter of two years from grant date or upon the recipient reaching retirement eligible age (59½ years). During 2024, 2023, and 2022, certain senior leadership of the company received RSUs in February which vest over a period of 2 to 4 years. The stock is issued to employees upon vesting. The company satisfies RSUs with newly issued shares, and satisfies restricted and unrestricted stock awards, DSUs, and performance awards with treasury shares. In addition to the RSUs and LTIP awards granted during the three-year period ended December 31, 2024, presented below, the company awarded 13,000, 18,000 and 20,000 DSUs in 2024, 2023 and 2022, respectively. The 1,300 SARs awards outstanding at December 31, 2024, for which no shares of common stock can be issued because the awards must be cash-settled upon exercise, have a weighted-average exercise price of $42.83.

The weighted average remaining life before vesting of the outstanding RSUs as of December 31, 2024, is 1.6 years. The fair value of RSUs vesting during 2024, 2023, and 2022 was $56.2 million, $58.3 million, and $79.1 million, respectively, and was net-share settled such that the company withheld shares with value equivalent to the employees’ minimum statutory obligation for the applicable income and other employment taxes and remitted the cash to the appropriate taxing authorities. The total shares withheld in 2024, 2023, and 2022 were approximately 287,000, 342,000, and 249,000 shares, respectively, and were based on the value of the RSUs on their vesting dates as determined by the company’s closing stock price.

Long-Term Incentive Compensation Program (LTIP)

The company maintains an LTIP performance-based program directed toward key senior leadership of the company, as determined at the discretion of the Compensation Committee of the Board of Directors. Awards are in shares of the company’s common stock using the stock price on the first day of the performance period to convert each key senior executive’s predetermined multiple of annual base salary. The performance period is generally three years; however, transition awards can be issued with a shorter performance period. Performance is measured in terms of equal portions of four growth and profitability measures, as compared to the same measures, similarly treated, of a pre-established group of steel sector competitors. Awards earned can range from zero to 100% of the shares awarded, and award shares vest immediately once earned on the basis of performance.

2018 Executive Incentive Compensation Plan (2018 Executive Plan)

The 2018 Executive Plan provides for eligibility of certain senior leadership of the company to receive cash and stock bonuses based on predetermined formulas. The company’s shareholders approved the 2018 Executive Plan in May 2018 and 2.0 million shares of company stock were reserved for grant through February 28, 2028. At times a portion of the bonus may be distributed in shares of the company’s stock, of which one-third of the shares vest immediately and the remaining shares vest in equal annual installments over an additional two-year service-based vesting period requirement. At December 31, 2024, 2023, and 2022, 1.3 million, 1.3 million, and 1.4 million shares, respectively, under the 2018 Executive Plan remained available for grant. Pursuant to the 2018 Executive Plan, 17,000, 29,000, and 26,000 shares were awarded with a market value of $2.2 million, $3.5 million, and $3.2 million for the 2024, 2023, and 2022 award years, respectively.

Note 7. Fair Value Measurements

Accounting standards provide a comprehensive framework for measuring fair value, sets forth a definition of fair value and establishes a hierarchy prioritizing the inputs to valuation techniques, giving the highest priority to quoted prices in active markets for identical assets and liabilities and the lowest priority to unobservable value inputs. Levels within the hierarchy are defined as follows:

●

Level 1—Unadjusted quoted prices for identical assets and liabilities in active markets;

●

Level 2—Quoted prices for similar assets and liabilities in active markets (other than those included in Level 1) which are observable for the asset or liability, either directly or indirectly; and

●

Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

Note 7. Fair Value Measurements (Continued)

The following table sets forth financial assets and liabilities measured at fair value on a recurring basis in the consolidated balance sheet and the respective levels to which the fair value measurements are classified within the fair value hierarchy as of December 31 (in thousands):



			Quoted Prices		Significant
			in Active		Other		Significant
			Markets for		Observable		Unobservable
			Identical Assets		Inputs		Inputs
	Total		(Level 1)		(Level 2)		(Level 3)
December 31, 2024
Short-term investments	$	147,811	$	-	$	147,811	$	-
Commodity futures – financial assets		19,323		-		19,323		-
Commodity futures – financial liabilities		6,272		-		6,272		-

December 31, 2023
Short-term investments	$	721,210	$	-	$	721,210	$	-
Commodity futures – financial assets		2,483		-		2,483		-
Commodity futures – financial liabilities		9,305		-		9,305		-

The carrying amounts of financial instruments including cash equivalents approximate fair value (Level 1). The fair values of short-term investments commodity futures contracts are estimated by the use of quoted market prices, estimates obtained from brokers, and other appropriate valuation techniques based on references available (Level 2). The fair value of long-term debt, including current maturities, as determined by quoted market prices (Level 2), was approximately $3.0 billion and $2.8 billion at December 31, 2024 and 2023, respectively (with a corresponding carrying amount in the consolidated balance sheet of $3.2 billion and $3.1 billion at December 31, 2024 and 2023, respectively).

Note 8. Commitments and Contingencies

The company has entered into certain commitments with suppliers which are of a customary nature. Commitments have been entered into relating to future expected requirements for commodities such as electricity, water, natural gas and its transportation services, fuel, air products, zinc, and electrodes. Certain commitments contain provisions which require that the company “take or pay” for specified quantities at fixed prices without regard to actual usage for periods of generally up to 5 years for physical commodity requirements and commodity transportation requirements, with some extending beyond, and for up to 15 years for air products and 27 years for water products. The company utilized such “take or pay” requirements during the past three years under these contracts. The company believes that production requirements will be such that consumption of the products or services purchased under these commitments will occur in the normal production process.

The company’s commitments for these agreements with “take or pay” or other similar commitment provisions for the years ending December 31 are as follows (in thousands):


2025	$	358,976
2026		57,430

The company’s commitments for operating leases are discussed in Note 11. Leases.

The company is involved in various litigation matters, including administrative and regulatory proceedings, that arise in the ordinary course of business, none of which are expected to have a material impact on the company’s financial condition, results of operations, or liquidity.

Note 9. Transactions with Affiliated Companies

The company purchases and sells recycled and scrap metal, steel, and purchases transportation services with other smaller affiliated companies, including equity method investments. These transactions for the years ended December 31, are as follows (in thousands):


	2024		2023		2022

Note 10. Retirement Plans

The company sponsors several 401(k) retirement savings and profit sharing plans (Plans) for eligible employees, which are considered “qualified plans” for federal income tax purposes. The company’s total expense for the Plans was $209.0 million, $312.4 million, and $466.9 million for the years ended December 31, 2024, 2023, and 2022, respectively. Profit sharing expense for eligible employees is 8% of consolidated pretax income excluding noncontrolling interests and other items. The resulting profit sharing expense under the Plan was $165.2 million, $264.6 million, and $421.6 million for the years ended December 31, 2024, 2023, and 2022, respectively; of which up to $132.2 million, $211.6 million, and $337.2 million, respectively, was directed by the company’s board of directors to be contributed to the Plans (subject to total Plan contribution limitations), with the remaining amounts each year paid directly in cash to the Plans’ participants.

Note 11. Leases

The company has operating leases relating principally to transportation and other equipment, and some real estate. The company determines if an arrangement contains a lease at inception, which generally occurs when the arrangement identifies a specific asset that the company has the right to direct the use of and obtain substantially all of the economic benefit from use of the identified asset. Certain of the lease agreements contain rent escalation clauses (including fixed and index-based escalations), and options to extend or terminate the lease. For purposes of calculating operating lease obligations, the company’s lease terms include options to extend the lease when it is reasonably certain that the company will exercise such option. The company uses its incremental borrowing rate at lease commencement to determine the present value of lease payments. The incremental borrowing rate is the rate of interest the company could borrow on a collateralized basis over a similar term with similar payments. Operating lease expense is recognized on a straight-line basis over the lease term.

Note 12. Segment Information

The company’s chief operating decision maker (CODM), who is the Chief Executive Officer, analyzes the results of the business through the following reportable segments: steel operations, metals recycling operations, steel fabrication operations, and aluminum operations. In the fourth quarter 2024, results from an entity previously reported within the metals recycling operations segment were moved to the aluminum operations segment, consistent with a change in how the CODM manages the business. Segment information provided within this Form 10-K has been recast for all prior periods presented consistent with the current reportable segment presentation. The segment operations are more fully described in Note 1. Description of the Business and Summary of Significant Accounting Policies to the consolidated financial statements.

The CODM assesses segment performance and allocates resources primarily based on operating income. The CODM uses operating income to allocate operating and capital resources and assesses performance of each segment by comparing actual operating income results to historical and previously forecasted financial information. The accounting policies of the reportable segments are consistent with those described in Note 1 to the consolidated financial statements. Intra-segment sales and any related profits are eliminated in consolidation.

The company’s segment results, with prior periods recast consistent with our current reportable segments presentation, including disaggregated revenue by segment to external, external non-United States, and other segment customers, are as follows (in thousands):
