ITEM 1.       BUSINESS
​

​

​

Steel Dynamics, Inc. is a leading industrial metals solutions company, with facilities located throughout the United States and Mexico. The company operates a circular manufacturing model, producing high-quality, lower-carbon-emission products with recycled scrap as the primary input. Steel Dynamics is one of the largest domestic steel producers and metals recyclers in North America based on estimated steelmaking and steel coating capacity of approximately 16 million tons and actual metals recycling volumes as of December 31, 2025, with one of the most diversified product and end market portfolios in the domestic steel industry, combined with a meaningful downstream steel fabrication platform. The company also has aluminum operations, further diversifying its product offerings to supply aluminum flat rolled products with higher recycled content to the countercyclical, sustainable beverage can industry, as well as the automotive and industrial sectors. The company’s primary sources of revenue are currently derived 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 joist and deck products.
We refer to our founding principles as our six core strategic pillars. These pillars unify our teams around a common focus and provide the foundation for how we operate and grow. Our unique entrepreneurial culture and business model create operational and financial advantages and support the responsible use of resources across diverse economic environments. Innovation in all forms is essential to our success, and our teams focus on working smarter within existing operations while pursuing opportunities for continued growth. This includes developing solutions for our teammates, customers, suppliers, and other stakeholders, as well as finding ways to operate with fewer resources and less environmental impact. The consistent execution of our six strategic pillars drives our long-term 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.

Unique Entrepreneurial Culture
Our entrepreneurial culture is the foundation of our success and is driven by our extensive, performance-based incentive compensation philosophy that spans from teammates on the plant floor to senior leadership. More than 60% of a production team member’s total potential compensation is “at risk” and tied to quality production and cost-effectiveness metrics. More than 85% of our senior leadership team’s total potential compensation is “at risk” and linked to companywide financial metrics that encourage long-term value creation, including return on equity, growth, cash generation, and return on invested capital. 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 portfolios in the domestic steel industry and a proven track record of profitable growth. We have driven diversification across both end markets and value-added product offerings to sustain higher volumes and profitability through varying market environments. Approximately 70% of our steel and steel fabrication sales are considered value-added.
​
Throughout our history and today, we have focused on providing differentiated supply-chain solutions that help our customers increase efficiency, reduce time and costs, and support decarbonization opportunities. Growing alongside our customers in this way has been instrumental in building long-lasting relationships and advancing product development.
​
The majority of our scrap consuming operations are located near sustainable sources of scrap metal and close to our customer base, creating freight savings on inbound scrap and outbound finished products. This proximity also allows us to provide consistent, on-time delivery with relatively short lead times, further strengthening our customer relationships.
​
This diversified product portfolio enables us to access a broad range of markets and serve a large customer base, while helping to mitigate exposure to any single product or end market and supporting higher through-cycle mill utilization. Our value-added product offerings also help balance our exposure to commodity grade products supplied by other manufacturers.
We will continue to seek additional opportunities, including our entry into 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. As with all of our growth initiatives, we seek to competitively differentiate ourselves through service, product capability and quality, and integrated supply-chain solutions.
Vertically Connected Businesses and Pull-Through Volume Advantage
Our vertically connected businesses support our higher through-cycle steel production and overall profitability. Our internal manufacturing operations provide a significant competitive advantage by contributing to more stable through-cycle earnings and cash flow generation. Our steel fabrication operations and downstream processing facilities consume significant volumes of steel. During weaker steel demand environments, we can source their steel needs internally, and during stronger steel demand environments, we may also purchase steel externally. Ultimately, we optimize our companywide profitability and minimize earnings volatility. In 2025, our own steel consuming businesses purchased 1.8 million tons of steel from our steel mills, representing 13% of our total 2025 steel shipments.
A strategic and synergistic relationship exists between our electric arc furnace (EAF) steel mills and our metals recycling operations, as well as between our aluminum operations and our metals recycling operations. Our metals recycling platform is the largest supplier of recycled ferrous scrap to our steel operations and the largest supplier of recycled aluminum scrap to our aluminum operations. This circular model allows us to reduce companywide working capital, as lower scrap inventory volume is required at our steel mills and aluminum operations. We are also able to source higher-quality scrap for our steel mills and aluminum operations, increasing availability, optimizing costs, and improving quality.

Technologically Advanced, Low-Cost, Highly Efficient Operations
We have some of the most technologically advanced and environmentally responsible steel mills and aluminum operations 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 metals solutions companies.
Sustainability
Our commitment to all aspects of sustainability is embedded in our founding principles, which emphasizes valuing our people, our partners, our communities, and our environment. These strategic principles guide 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 steelmaking technology, which uses recycled ferrous scrap as the primary raw material. Our new recycled aluminum flat rolled products mill uses recycled aluminum scrap as its primary raw material and is engineered to provide an energy-efficient, lower-environmental-impact product alternative compared to average aluminum flat rolled production. These investments allow us to produce high-quality, lower-embodied-carbon steel and aluminum products for our customers and drive 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 have 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 steel and aluminum 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 mills in the world, we recognize the need for continuous improvement. Our biocarbon production facility located in Columbus, Mississippi uses high-temperature pyrolysis to convert sustainably sourced biomass to high-purity biocarbon. We plan to 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 began operations in the second half of 2025. This investment represents a significant step toward the decarbonization of our steel mills.
Experienced Leadership Team / Fosters an Entrepreneurial Culture
Our senior leadership team is highly experienced and has a proven track record in the steel, metals recycling, and steel fabrication industries, as well as building and operating low-cost melting, casting and rolling facilities, such as our recycled aluminum flat rolled products mill. Our leadership objectives are closely aligned with our shareholder interests through meaningful stock ownership and performance-based incentive compensation programs that are tied to the company’s profitability and operational performance in relation to our steel manufacturing peers. We emphasize decentralized operational decision making and accountability, while maintaining appropriate corporate governance and risk oversight. We reward teamwork, innovation, and operating efficiency, and focus on maintaining the effectiveness of our performance-driven incentive bonus plans designed to maximize overall productivity and align the interests of our leadership and teams with our shareholders.

Compensation Structure
We believe in empowering our teams and rewarding them for their achievements through a four-tiered, performance-based compensation framework. The components of our compensation programs are designed to balance high-return growth, disciplined capital investment, low-cost operations, and effective risk mitigation. By rewarding our teams based on their performance at the individual, team, company, and shareholder levels, we believe our compensation structure achieves strong alignment with the interests of our external constituents.
​
This alignment 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 2025, our companywide team retention was approximately 83%, 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.

Steel Operations Segment

​
Our steel operations consist of electric arc furnace steel mills that produce steel from ferrous scrap and scrap substitutes, using continuous casting and automated rolling mills, along with numerous steel coating, processing, and warehouse operations. Our steel operations sell directly to end users, steel processors, steel fabricators, and service centers. These products are used across a broad range of end markets, including construction, automotive, manufacturing, transportation, heavy and agricultural equipment, energy, and pipe and tube markets, including oil country tubular goods (“OCTG”).
Our steel operations accounted for 72%, 69%, and 67% of our consolidated net sales during 2025, 2024, and 2023, respectively. We are predominantly a domestic steel company. Export sales represented approximately 4%, 6%, and 8% of our steel segment net sales during 2025, 2024, and 2023, respectively.
Our steel operations consist primarily of steelmaking and a broad range of coating operations. In 2025, we had approximately 9.4 million tons of annual flat roll steel production capacity. We also had 2.0 million tons of flat roll steel processing capacity through The Techs and our Heartland Flat Roll Division. Through United Steel Supply (“USS”) and New Process Steel, L.P. (“NPS”) (acquired December 1, 2025), we also have distribution and processing of metallic coated and pre-painted products. In addition, we had annual flat roll galvanizing capability of 5.5 million tons and painting capability of 2.0 million tons. Our long products divisions had approximately 4.6 million tons of annual steel production capacity.
Capacities represent maximum estimated manufacturing capabilities based on steel mill configuration and related team member support and do not reflect expected production volumes in any given year. Estimates of steel mill capacity are also highly dependent on product mix. Each of our steel mills is capable of producing a wide range of products and sizes; accordingly, capacity estimates assume a typical product mix.

​

Customers. Steel processors and service centers typically act as intermediaries between primary sheet steel producers and end-user manufacturers that require additional processing of hot-rolled coils. Processing performed by these intermediaries includes pickling, galvanizing, cutting to length, slitting, leveling, blanking, shape correcting, edge rolling, shearing, and stamping. We believe steel processors and service centers will continue to be an integral part of our customer base.
Our Columbus and Sinton Flat Roll Divisions enable us to capitalize on industrial markets in the Southern United States and Mexico and to further expand our customer base for painted products, line pipe, and other pipe applications. Galvanized flat rolled products produced by our Butler, Columbus, and Sinton Flat Roll Divisions are similar and are sold to a generally similar customer base.

Customers. The principal customers for our structural steel products are steel service centers, steel fabricators and various manufacturers. Service centers provide key distribution channels for the mills and value-add services to the end-user. The steel rail marketplace in the United States, Canada, and Mexico is specialized and defined, with seven Class I railroads and a large distribution network.
SBQ products are principally consumed by cold finishers, forgers, intermediate processors, OEM manufacturers, steel service centers, and distributors, as well as pull-through volume to Vulcan. Our MBQ products are sold primarily to steel service centers, as well as reinforcing steel bar distributors, joist producers (such as our New Millennium Building Systems), and OEMs. Some of the excess steel billet production at the Roanoke Bar Division is sold to mills without sufficient melting capacities, including our Steel of West Virginia facility. Our steel fabrication operations also purchase angles from Roanoke Bar Division. Steel of West Virginia’s customers are primarily OEMs producing solar panel structures, truck trailers, industrial lift trucks, merchant products, guardrail posts, manufactured housing, mining, and off-highway construction equipment. Steel of West Virginia’s flexible manufacturing capabilities enable us to meet demand for a variety of custom-ordered and designed products. Many of these products are produced in small quantities for low volume end-uses resulting in a wide variety of customers, the largest of which are in the truck trailer and industrial lift truck industries.
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.

​
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 aluminum used beverage cans, copper wire, 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 and other independent scrap dealers.

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, baling, and breaking. Our major ferrous products include heavy

16

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 manufacturers (including our aluminum operations), ingot manufacturers, brass and bronze ingot makers, copper refineries, 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.

Competition. We compete with other North American joist and steel deck producers primarily on the basis of price, quality, customer service, and proximity to customers. Our national footprint enables us to efficiently service the entire domestic non-residential construction market, which is particularly valuable for serving national accounts such as large retail chains, distribution warehouse facilities, and data center developers.
​

Aluminum Operations Segment

​
Our aluminum operations consist of a 650,000-metric-ton recycled aluminum flat rolled products mill in Columbus, Mississippi; two 150,000-metric-ton satellite recycled aluminum slab centers, one in Central Mexico and one under construction in the Southwest U.S.; and an ancillary recycled aluminum deox-rod facility. The flat rolled products mill produces flat rolled aluminum coil products from aluminum scrap and is a complementary extension of our metals recycling platform. Our product offerings will be supported by various value-added finishing lines that are being commissioned, including two CASH (Continuous Annealing Solutions Heat Treating) lines, a can end and tab coating line, and downstream processing and packaging lines.
The results of our aluminum operations for 2025, 2024, and 2023 largely consisted of sales from the ancillary recycled aluminum deox-rod facility, as well as construction, start-up, and commissioning costs associated with the recycled aluminum flat rolled products mill and satellite recycled aluminum slab centers. During the second half of 2025, the recycled aluminum flat rolled products mill produced finished products for the industrial and beverage can markets and achieved product certifications across multiple customers. In addition, the mill also successfully produced and qualified aluminum hot rolled coils for automotive applications. Aluminum operations accounted for 2% of our consolidated net sales in 2025, and 1%, in each of 2024 and 2023.
Products. Our aluminum operations provide flat rolled products with high recycled content to the countercyclical, sustainable beverage can industry, as well as the automotive and industrial sectors. Once the recycled aluminum flat rolled products mill reaches full production, we anticipate our aluminum operations product mix will consist of approximately 45% can sheet, 35% automotive, and 20% common alloy and industrial applications.
Customers and Markets. We have intentionally aligned the growth of our aluminum operations to serve a significant number of our existing carbon flat roll steel customers who also consume, or process, aluminum flat rolled products for automotive, appliance, construction, and other applications. We are further diversifying our end markets by supplying aluminum flat rolled products to the sustainable beverage can industry. We have developed our real estate to

Other Information

​
Sources, Availability, and Cost of Steel and Other Operations’ Raw Materials
Ferrous 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.
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 2025, 2024, and 2023 we consumed 13.0 million tons of metallic materials in our steelmaking furnaces, of which iron units other than scrap represented approximately 13% of the tons in 2025, and 15% of the tons in 2024 and 2023.
Aluminum Scrap Metals. The principal raw materials of our aluminum operations are raw aluminum (P1020) and recycled aluminum scrap derived from, among other sources, “home scrap,” generated internally at our rolling mill; industrial scrap, generated as a by-product of manufacturing, recycled from automotive and food beverage container manufacturers; and recycled materials from end-of-life trucks and automobiles, industrial products, and used food and beverage containers (“UBCs”). Recycled aluminum content varies by product, alloy, and end customer application. Food and beverage products typically achieve 85% or better recycled content, and industrial and automotive products’ recycled content is typically 65%. 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 aluminum operations could be increased or reduced in our metallic melt mix.
Many variables can impact ferrous and nonferrous scrap prices, all of which reflect the pushes and pulls of the supply-demand equation. These factors include the level of domestic 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 ferrous 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. ​
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 2025, 2024, and 2023. 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 Structural and Rail Division and Engineered Bar Products Division have a combination of fixed pricing and market

19

Table of Contents

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.
Research and Development
Our research and development activities have consisted of efforts to expand, develop, and improve our products and operating processes, including those at our recycled aluminum flat rolled products mill and Sinton Flat Roll Division, as well as our efforts to develop and improve renewable product alternatives, such as our 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, use of water, 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 raw materials or 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 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

20

Table of Contents

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 monitoring and 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.
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. Some jurisdictions also have regulations governing the appropriation and use of water and other raw materials. 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 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 industries, as well as the industries of many of our customers and suppliers upon whom we are dependent, are 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 imposition of new tax laws or 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 industries, 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 agricultural equipment, energy, food packaging, beverage can and pipe and tube (including OCTG) markets, and many of 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 industries or in the industries we serve, we may have difficulty increasing or maintaining our level of sales or profitability. A downturn in our industries 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 for 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 steel operations financial condition, results of operations, 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. 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 steel business, results of operations, financial condition and cash flows.
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 metals industries and some of the other industries we serve.
The steel and aluminum manufacturing business is cyclical in nature, and the selling price of the products 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 and aluminum products is directly affected by demand for our products in other cyclical industries, such as construction, automotive, manufacturing, transportation, heavy and agricultural equipment, energy, food packaging, beverage can 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 or aluminum 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 and aluminum producers require large amounts of raw materials, including ferrous and aluminum 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 materials of our EAF steel operations and aluminum operations are recycled scrap derived from, among other sources, “home scrap,” generated internally at steel and aluminum mills themselves; industrial scrap, generated as a by-product of manufacturing; obsolete scrap, recycled from end-of-life automobiles, appliances, machinery, food packaging and used beverage cans; 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 and aluminum 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 and aluminum. 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 ferrous scrap prices. Additionally, the construction of any new aluminum flat rolled products mills may also lead to increased demand in aluminum scrap possibly resulting in higher aluminum scrap prices. While our vertical integration with our metals recycling business and liquid pig-iron operations are expected to enable us to continue being a cost-effective supplier to our own steelmaking and aluminum 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 heightened during times of war or hostilities. 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, among other things, 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 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;
● the use and treatment of groundwater and surface water;
● the remediation of equipment, product, soil or water 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 or affected by 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, aluminum, and copper production operations, is a significant factor in our business. We are required to obtain

25

Table of Contents

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 appropriate 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 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 and aluminum companies and scrap processors conduct business are highly competitive and became even more so due to consolidations in these industries. Additionally, in many applications, steel and aluminum compete with other materials, such as aluminum or steel, as the case may be, cement, composites, plastics, carbon fiber, titanium, tin, glass, wood, and paperboard. Increased use of alternative materials for any reason, including as a response to regulations or customer demands, could decrease demand for steel and aluminum or force other 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. 
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 or other scrap sources, such as used beverage cans, 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, sell, or consume for our steelmaking or aluminum operations. Further, additional EAF steel mill or aluminum production facility construction or blast furnace mills investing in EAF mills could increase the demand for ferrous and aluminum scrap, potentially resulting in higher scrap prices or periods of decreased scrap supply. Any inability to secure scrap for our steelmaking and aluminum operations 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 steel, aluminum 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 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, ramp-up or qualification of products;
● 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 and qualification, technology development or customer acquisition and penetration being more costly, time-consuming 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, acquisition targets or acquired businesses;
● 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, political, regulatory or other disputes or litigation related to new operations, acquisition targets or acquired businesses;
● the risk of becoming more highly leveraged;

28

Table of Contents

● the risk of contractual or operational liability to other joint 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 new facilities has adversely affected and may continue to 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 condition, 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.
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 equipment, such as our EAFs, continuous casters, aluminum melting, 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 during the start-up and ramp-up of new facilities, 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.  Delayed delivery of our products to customers who require on-time delivery from us may cause customers to purchase alternative products, reschedule their own production, or incur other incremental costs. Customers may be able to pursue financial claims against us for their incremental costs, and we may incur costs to correct such problems in addition to any liability resulting from such

29

Table of Contents

claims. Interruptions may also harm our reputation among actual and potential customers, potentially resulting in a loss of business. These disruptions may adversely affect our business, financial condition, results of operations and cash flows.
We may experience difficulties in the launch or production ramp-up of new products which may adversely affect our business.
As we ramp up manufacturing processes for newly introduced products, we may experience difficulties, including manufacturing disruptions, delays, or other complications, which could adversely affect our ability to serve our customers, our reputation, our costs of production and, ultimately, our business, financial condition, results of operations and cash flows.
Our aluminum operations depend on a core group of significant customers.
We have a relatively concentrated group of aluminum customers. Most of these customers have one or more sizable sales agreements with us. If one or more of these customers experienced a prolonged period of adverse demand, depressed business activity or financial distress, if any of these customers breached or sought relief from its contractual obligations under its sales agreements with us or if any of these customer relationships otherwise ended or materiality deteriorated and such lost business was not successfully replaced, our aluminum operations financial condition, results of operations, and cash flows may be adversely affected.
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 existing debt agreements contain, 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 in which we participate, 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.

30

Table of Contents

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 1B.          UNRESOLVED STAFF COMMENTS
None.
​
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 utilize 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 Information Security Team 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 our 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.
​

Table of Contents

In general, our incident response process utilizes 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 Information Security Team engages in 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.
​
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, material 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. This group contains members with a master’s degree in information security, as well as individuals with over 20 years of experience in cybersecurity. The ISG is an internal, collaborative working group that ensures our cybersecurity program is adequately responsive to the evolving threat landscape.

ITEM 7.        MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
Forward-Looking Statements
This report contains some predictive statements about future events, including statements related to conditions in domestic or global economies, conditions in steel, aluminum, and recycled metals market places, Steel Dynamics' revenues, costs of purchased materials, future profitability and earnings, and the operation of new, existing or planned facilities. These statements, which we generally precede or accompany by such typical conditional words as "anticipate", "intend", "believe", "estimate", "plan", "seek", "project", or "expect", or by the words "may", "will", or "should", are intended to be made as "forward-looking", subject to many risks and uncertainties, within the safe harbor protections of the Private Securities Litigation Reform Act of 1995. These statements speak only as of this date and are based upon information and assumptions, which we consider reasonable as of this date, concerning our businesses and the environments in which they operate. Such predictive statements are not guarantees of future performance, and we undertake no duty to update or revise any such statements. Some factors that could cause such forward-looking statements to turn out differently than anticipated include: (1) domestic and global economic factors; (2) global steelmaking overcapacity and imports of steel, together with increased scrap prices; (3) the cyclical nature of the metals industries and the industries we serve; (4) 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; (5) cost and availability of electricity, natural gas, oil, and other energy resources are subject to volatile market conditions; (6) increased environmental, greenhouse gas emissions and sustainability considerations from our customers and investors or related regulations; (7) compliance with and changes in environmental and remediation requirements; (8) significant price and other forms of competition from other steel and aluminum producers, scrap processors and alternative materials; (9) availability of an adequate source of supply of scrap for our metals recycling operations; (10) cybersecurity threats and risks to the security of our sensitive data and information technology; (11) the implementation of our growth strategy; (12) our ability to retain, develop and attract key personnel; (13) litigation and legal compliance; (14) unexpected equipment downtime or shutdowns; (15) difficulties in the launch or production ramp-up of new products; (16) our aluminum operations depend on a core group of significant customers; (17) governmental agencies may refuse to grant or renew some of our licenses and permits; (18) our existing debt agreements contain, and any future financing agreements may contain, restrictive covenants that may limit our flexibility; and (19) the impacts of impairment charges.
More specifically, we refer you to our more detailed explanation of these and other factors and risks that may cause such predictive statements to turn out differently, as set forth in the sections titled Special Note Regarding Forward-Looking Statements at the beginning of Part I of this Report and Item 1A. Risk Factors , as well as in other subsequent reports we file with the Securities and Exchange Commission. These reports are available publicly on the Securities and Exchange Commission website, www.sec.gov , and on our website, www.steeldynamics.com under “Investors – SEC Filings.”
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 and aluminum, 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.
2025 Overview
During 2025 we achieved record steel shipments of 13.7 million tons. Underlying domestic steel demand was stable during 2025, as imports declined from the elevated levels experienced during the first half of the year and as the Sinton Flat Roll Division’s year-over-year operating performance improved. Our metals recycling operations segment achieved notable improvement in operating income in 2025 compared to 2024 on higher ferrous metals volumes and higher ferrous and nonferrous pricing. Our steel fabrication operations experienced historically strong, yet moderating product pricing compared to 2024, with stabilization in selling values realized in the fourth quarter of 2025. Finally, our aluminum operations segment achieved successful production and qualifications of industrial, beverage can, and automotive quality flat rolled aluminum products, with shipments commencing in the late second half of 2025.
Consolidated net sales were $18.2 billion during 2025, with cash flow from operations of $1.4 billion. Metal spread compression in our steel and, particularly, steel fabrication segments resulted in lower operating income in 2025 compared to 2024. Consolidated operating income for 2025 decreased $467.1 million, or 24%, to $1.5 billion, compared to $1.9 billion in 2024. Net income attributable to Steel Dynamics, Inc. for 2025 decreased $351.5 million, or 23%, to $1.2 billion, compared to 2024. Diluted earnings per share attributable to Steel Dynamics, Inc. was $7.99 for 2025, compared to $9.84 for 2024.
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, 2024, for additional information regarding results of operations for the year ended December 31, 2024, as compared to the year ended December 31, 2023, and segment operating results for 2024 as compared to 2023.

Steel Operations Segment Results 2025 vs. 2024
During 2025, our steel operations achieved record annual shipments of 13.7 million tons (12.3 million excluding intra-segment), 9% higher than 2024 shipments, primarily due to significant sales volume increases at our Sinton and Heartland facilities as the four new value-added lines operated for a full year in 2025. Customer order activity and steel demand were strong during 2025, particularly as imports declined in the latter half of the year. Demand was supported by manufacturing onshoring, infrastructure program funding, lower interest rates, and the increasing regionalization of supply chains in the US. Despite these favorable market demand conditions, in the face of trade policy uncertainty, average selling prices were modestly lower during 2025 compared to 2024. Steel segment average selling prices decreased 1%, or $14 per ton, compared to 2024. Net sales for the steel operations segment were 7% higher in 2025 when compared to 2024, due to a 9% increase in segment shipments.
​
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 was unchanged on a per net ton basis in 2025 compared to 2024, consistent with overall steady domestic scrap pricing noted below in the metals recycling operations segment discussion.
​
As a result of average selling prices decreasing more than scrap costs, 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 2% in 2025 compared to 2024. Due to metal spread compression, operating income for the steel operations decreased 10% to $1.4 billion in 2025 compared to 2024.
Metals Recycling Operations Segment

​
Metals recycling operations include our Omni ferrous and nonferrous processing, transportation, marketing, brokerage, and scrap management services located throughout the United States and in Central and Northern 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 2025 and 2024, 65% and 62%, respectively, of metals recycling operations ferrous scrap was sold to our own steel mills, as our steel mill utilization increased to 86% in 2025 compared to 81% 2024, with production levels at our Sinton facility increasing during 2025. Metals recycling operations accounted for 11% of our consolidated net sales during 2025 and 2024.

Metals Recycling Operations Segment Results 2025 vs. 2024
During 2025, our metals recycling operations continued to benefit from solid domestic steel industry demand, resulting in increased ferrous scrap shipments compared to 2024. Net sales for our metals recycling operations in 2025 increased 5% compared to 2024, driven by increased ferrous volumes and increased selling prices for both ferrous and nonferrous metals. Ferrous and nonferrous scrap average selling prices increased 2% and 7%, respectively, during 2025 compared to 2024. Ferrous shipments increased 5% and nonferrous shipments decreased 5% in 2025 compared to 2024.
​
Ferrous metal spreads (which we define as the difference between average selling prices and the cost of purchased scrap) were flat, while nonferrous metal spreads, primarily aluminum, increased 24% in 2025 compared to 2024, with aluminum prices rising in the fourth quarter of 2025. As a result of these volume and metal spread changes, metals recycling operations operating income in 2025 of $97.2 million increased 27% from 2024.
​
Steel Fabrication Operations Segment

​
Steel fabrication operations include our 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 steel joists, joist girders, and steel deck systems used within the non-residential construction industry. Steel fabrication operations accounted for 8% and 10% of our consolidated net sales during 2025 and 2024, respectively.
​

​
Steel Fabrication Operations Segment Results 2025 vs. 2024
Net sales for the steel fabrication operations decreased 20% during 2025 compared to 2024, as average selling prices decreased 13% and volumes decreased 8% compared to 2024. Order activity remained strong during 2025, with our order backlog maintaining solid levels and extending through the first half of 2026, supported by stable and historically strong pricing. Demand was largely driven by the commercial, data center, manufacturing, warehouse, and healthcare sectors.
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 7% in 2025, as compared to 2024. Lower selling prices per ton offset decreased steel input costs per ton,

42

Table of Contents

resulting in contraction of metal spread (which we define as the difference between average selling prices and the cost of purchased steel) by 17% in 2025 compared to 2024. Metal spread compression coupled with decreased volume resulted in operating income decreasing 39% to $407.4 million in 2025, compared to $667.0 million in 2024.

Aluminum Operations Segment

​
Our aluminum operations consist of a 650,000-metric-ton recycled aluminum flat rolled products mill in Columbus, Mississippi; two 150,000-metric-ton satellite recycled aluminum slab centers, one in Central Mexico and one under construction in the Southwest U.S.; and an ancillary recycled aluminum deox-rod facility. The recycled aluminum flat roll products mill produces flat rolled aluminum products from aluminum scrap and is a complementary extension of the company’s metals recycling platform. Our product offerings will be supported by various value-added finishing lines that are still under construction, including two CASH (Continuous Annealing Solutions Heat Treating) lines, a can end and tab coating line, and downstream processing and packaging lines. Aluminum operations accounted for 2% and 1% of our consolidated net sales during 2025 and 2024, respectively.
Aluminum Operations Segment Results 2025 vs. 2024
During 2025, the results of this segment largely consisted of sales from the ancillary recycled aluminum deox-rod facility, as well as construction, start-up, and commissioning costs associated with the recycled aluminum flat roll products mill and satellite recycled aluminum slab centers. The flat rolled products mill shipped 15,000 metric tons of finished product during the second half of 2025. In 2025, aluminum operations sales, including those of our ancillary recycled aluminum deox-rod facility, totaled $473.9 million, an increase of 49%, compared to $318.7 million in 2024 primarily due to the volumes from the aluminum flat rolled products mill beginning in the second half of 2025.
