#### PART I

#### Special Note Regarding Forward-Looking Statements
Throughout this report, or in other reports or registration statements filed from time to time with the Securities and Exchange Commission under the Securities Exchange Act of 1934, or under the Securities Act of 1933, as well as in documents we incorporate by reference herein or here-from, or in press releases or oral statements made by our officers or Regulation FD authorized representatives, we may make statements that express our opinions, expectations, or projections regarding future events or future results, in contrast with statements that reflect present or historical facts. These predictive 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 operate as "forward-looking statements" of the kind permitted by the Private Securities Litigation Reform Act of 1995, incorporated in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Such forward-looking statements involve both known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. That legislation protects such predictive and cautionary statements by creating a "safe harbor" from liability in the event that a particular prediction does not turn out as anticipated.

While we always intend to express our best judgment when we make statements about what we believe will occur in the future, and although we base these statements on assumptions that we believe to be reasonable when made, these forward-looking statements are not a guarantee of performance, and you should not place undue reliance on such statements. Forward-looking statements are subject to many uncertainties and other variable circumstances, many of which are outside of our control, that could cause our actual results and experience to differ materially from those we thought would occur.

The following listing represents some, but not necessarily all, of the factors that may cause actual results to differ from those we may have anticipated or predicted:

We also refer you to and urge you to carefully read the section entitled *Risk Factors* at Item 1A of this report to better understand some of the principal risks and uncertainties inherent in our businesses or in owning our securities, as well as the section entitled *Management's Discussion and Analysis of Financial Condition and Results of Operations* at Item 7*.* You should also review the notes to consolidated financial statements under headings in Note 1. *Use of Estimates* and in Note 8. *Commitments and Contingencies*.

Any forward-looking statements which we make in this report, or in any of the documents that are incorporated by reference herein or here-from, speak only as of the date of such statement, and we undertake no ongoing obligation to update such statements. Comparisons of results between current and any prior periods are not intended to express any future trends or indications of future performance, unless expressed as such, and should only be viewed as historical data.

**ITEM 1.&nbsp;&nbsp;&nbsp;&nbsp; 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.

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

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

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

**Differentiated Model - Uniquely Steel Dynamics**

Competitively advantaged differentiation is central to our long-term value creation strategy. We distinguish ourselves across all aspects of our business through an overarching culture of excellence that drives how we operate, innovate, and serve our customers.

[**Table of Contents**](#TOC)

***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.

[**Table of Contents**](#TOC)

***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**<br>

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.

| Nonferrous metals (thousands of pounds) | 916502 | 965491 | 970445 |

---

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

[**Table of Contents**](#TOC)

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.

#### 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

[**Table of Contents**](#TOC)

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

[**Table of Contents**](#TOC)

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.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 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.

[**Table of Contents**](#TOC)

***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.

[**Table of Contents**](#TOC)

***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.

[**Table of Contents**](#TOC)

***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;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●the use and treatment of groundwater and surface water;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●the remediation of equipment, product, soil or water contamination;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●climate change legislation or regulation;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●the remediation and reclamation of land used in or affected by our operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●natural resource protections; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●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

[**Table of Contents**](#TOC)

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.

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

[**Table of Contents**](#TOC)

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:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● 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;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● the risk of new product development and qualification, technology development or customer acquisition and penetration being more costly, time-consuming or difficult than expected;

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● the potential disruption of ongoing operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● the diversion of financial resources or management attention to new operations, acquisition targets or acquired businesses;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● 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

[**Table of Contents**](#TOC)

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.

[**Table of Contents**](#TOC)

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.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; UNRESOLVED STAFF COMMENTS
None.

#### ITEM 1C.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 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**](#TOC)

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.

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**](#TOC)

***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.

[**Table of Contents**](#TOC)

#### 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**<br>

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.

[**Table of Contents**](#TOC)

#### 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**<br>

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.

![Graphic](stld-20251231x10k010.jpg)

#### 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,

[**Table of Contents**](#TOC)

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**<br>

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.

**Consolidated Results**<br>

#### Consolidated Results 2025 vs. 2024
***Selling, General and Administrative Expenses.*** Selling, general and administrative expenses of $765.3 million during 2025 increased 15% from $664.1 million during 2024 primarily due to an increase in payroll and benefits expense primarily related to construction, start-up, and commissioning costs associated with the recycled aluminum flat rolled products mill and satellite recycled aluminum slab centers during 2025. Selling, general and administrative expenses represented 4.2% and 3.8% of net sales during 2025 and 2024, respectively.

Profit sharing expense during 2025 of $123.0 million decreased 25% from $164.9 million during 2024, consistent with decreased pretax earnings. This decrease in profit sharing expense was the primary driver of decreased operating loss for our other operations of 11% in 2025 compared to 2024. Profit sharing expense for eligible employees is 8% of consolidated pretax income excluding noncontrolling interests and other items. Refer to Note 10. *Retirement Plans* to the consolidated financial statements elsewhere in this report for further information.

***Interest Expense, net of Capitalized Interest.*** During 2025, interest expense of $70.0 million increased 24% from $56.3 million during 2024. This increase is primarily a result of higher outstanding long-term debt balances during 2025 compared to 2024 due to our issuance of senior unsecured notes in March and November 2025.

***Other (Income) Expense, net.*** Net other income was $87.0 million in 2025, compared to $96.2 million in 2024, a decrease of $9.2 million due primarily to the impact of decreased interest income due to declining rates of return and lower invested cash balances in 2025 compared to 2024.

***Income Tax Expense.*** Income tax expense of $305.7 million, at an effective income tax rate of 20.5%, during 2025 decreased 29% compared to $432.9 million, at an effective income tax rate of 21.8%, during 2024, consistent with decreased pretax earnings. In July 2025, U.S. Congress enacted the One Big Beautiful Bill Act ("OBBBA"), which included significant provisions modifying the U.S. tax framework. These legislative changes did not and are not expected to have a material impact on 2025 and future effective tax rates, tax liabilities, and cash taxes. Refer to Note 4. *Income Taxes* to the consolidated financial statements elsewhere in this report for additional information.

[**Table of Contents**](#TOC)

Included in the balance of unrecognized tax benefits at December 31, 2025, are potential benefits of $27.2 million that, if recognized, would affect the effective tax rate. We recognize interest and penalties related to our tax contingencies on a net-of-tax basis in income tax expense. During the year ended December 31, 2025, we recognized income from the decrease of interest expense and penalties of $340,000, net of tax. In addition to the unrecognized tax benefits noted above, we had $3.7 million accrued for the payment of interest and penalties at December 31, 2025.

We file income tax returns in the U.S. federal jurisdiction as well as income tax returns in various state jurisdictions. The tax years 2022 through 2025 remain open to examination by the Internal Revenue Service and various state and local jurisdictions. At this time, we do not believe there will be any significant examination adjustments that would result in a material change to our financial position, results of operations or cash flows.

#### Liquidity and Capital Resources
***Capital Resources and Long-term Debt.*** Our business is capital intensive and requires substantial expenditures for, among other things, the purchase and maintenance of equipment used in our operations. Our short-term and long-term liquidity needs arise primarily from working capital requirements, capital expenditures, including expansion projects, principal and interest payments related to our outstanding indebtedness, dividends to our shareholders, potential stock repurchases and acquisitions or investments. We have met and intend to continue to meet these liquidity requirements primarily with available cash and cash provided by operations, long-term borrowings, and we also have availability under our unsecured Revolver. Our liquidity at December 31, 2025, is as follows (in thousands):

---

| | |
|:---|:---|
| Cash and equivalents | $769878 |
| Short-term and other investments | 255731 |
| Unsecured revolver availability | 1190820 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total liquidity | $2216429 |

---

Our total outstanding debt of $4.2 billion increased $980.2 million compared to December 31, 2024, due to our issuance of $600.0 million of 5.250% notes due 2035 and $400.0 million of 5.750% notes due 2055 in March 2025 and $650.0 million of 4.000% notes due 2028 and an additional $150.0 million of 5.250% notes due 2035 in November 2025 as described in Note 3, the proceeds of which were used to redeem our $400.0 million of 2.400% notes due June 2025 and our $400.0 million of 5.000% notes due December 2026, and other general corporate purposes. Our total long-term debt to capitalization ratio (representing our long-term debt, including current maturities, divided by the sum of our long-term debt, redeemable noncontrolling interests, and our total stockholders' equity) was 32.1% and 26.5% at December 31, 2025, and December 31, 2024, respectively.

Our unsecured credit agreement has a senior unsecured revolving credit facility (Facility), which provides a $1.2 billion Revolver and matures in July 2028. Subject to certain conditions, we have the ability to increase the Facility size by $500.0 million. The unsecured Revolver is available to fund working capital, capital expenditures, and other general corporate purposes. The Facility contains financial covenants and other covenants pertaining to our ability to incur indebtedness and permit liens on certain assets. Our ability to borrow funds within the terms of the unsecured Revolver is dependent upon our continued compliance with the financial and other covenants. At December 31, 2025, we had $1.2 billion of availability on the Revolver, $9.2 million of outstanding letters of credit and other obligations which reduce availability, and there were no borrowings outstanding.

The financial covenants under our Facility state that we must maintain an interest coverage ratio of not less than 2.50:1.00. Our interest coverage ratio is calculated by dividing our last-twelve-months (LTM) consolidated EBITDA as defined in the Facility (earnings before interest, taxes, depreciation, amortization, and certain other non-cash transactions as defined in the Facility) by our LTM gross interest expense, less amortization of financing fees. In addition, a debt to capitalization ratio of not more than 0.60:1.00 must be maintained. At December 31, 2025, our interest coverage ratio and debt to capitalization ratio were 13.33:1.00 and 0.32:1.00, respectively. We were in compliance with these covenants at December 31, 2025, and we anticipate we will continue to be in compliance during the next twelve months.

***Working Capital (representing excess of current assets over current liabilities).*** We generated cash flow from operations of $1.4 billion in 2025 compared to $1.8 billion in 2024. Working capital increased $1.1 billion, or 33%,

[**Table of Contents**](#TOC)

during 2025 to $4.4 billion at December 31, 2025, due to a $265.5 million increase in accounts receivable, as well as a $624.8 million dollar increase in inventories, primarily within our aluminum operations segment as our recycled aluminum flat rolled products mill began commissioning and operations in the second half of 2025.

***Capital Investments.*** During 2025, we invested $948.0 million in property, plant and equipment, primarily within our aluminum operations and steel operations segments, compared with $1.9 billion invested during 2024. Our liquidity of $2.2 billion and anticipated future operating cash flow generation is sufficient to provide for our planned 2026 capital requirements.

***Cash Dividends.*** As a reflection of continued confidence in our current and future cash flow generation capability and financial position, we increased our quarterly cash dividend by 9% to $0.50 per share in the first quarter of 2025 (from $0.46 per share for each quarter in 2024), resulting in declared cash dividends of $294.1 million during 2025, compared to $284.1 million during 2024. We paid cash dividends of $291.2 million and $282.6 million during 2025 and 2024, respectively. Our board of directors approves the payment of dividends on a quarterly basis. The determination to pay cash dividends in the future is at the discretion of our board of directors, after taking into account various factors provided by executive management, including our financial condition, results of operations, outstanding indebtedness, current and anticipated cash needs and growth plans.

***Other.*** Our board of directors has authorized share repurchase programs during prior years and the current year, the most recent of which occurred in February 2025 for a program of up to $1.5 billion of the company's common stock. Under the share repurchase programs, purchases take place as and when we determine in open market or private transactions made based upon the market price of our common stock, the nature of other investment opportunities or growth projects, our cash flows from operations, and general economic conditions. The share repurchase programs do not require us to acquire any specific number of shares, and may be modified, suspended, extended, or terminated by us at any time. The share repurchase programs do not have an expiration date. There were $900.9 million and $1.2 billion of share repurchases during 2025 and 2024, respectively. As of December 31, 2025, we had $801.0 million remaining available to purchase under the February 2025 share repurchase program. See Part II, Item 5. *Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities* for additional information.

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

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

***Long-term debt and estimated interest.*** Refer to Note 3. *Long-Term Debt* to the consolidated financial statements elsewhere in this report for our long-term debt maturities. Estimated interest payments on our senior unsecured notes were determined based on their outstanding balances through maturity at their contractual interest rates, as detailed in Note 3. Estimated interest payments also include a 0.175% commitment fee on our available Revolver, and an average interest rate of 5.44% on our other debt of $36.6 million. Our estimated interest payments are $180.5 million, $177.4 million, $168.5 million, $144.6 million, and $129.9 million, for the years 2026 through 2030, respectively, and $1.1 billion thereafter.

[**Table of Contents**](#TOC)

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

***Construction commitments.*** We have firm contracts with various vendors for the completion of certain construction projects at our various divisions at December 31, 2025. Refer to Note 8. *Commitments and Contingencies* to the consolidated financial statements elsewhere in this report for this information.

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

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

#### Other Matters

#### Environmental and Other Contingencies
We have incurred, and in the future will continue to incur, capital expenditures and operating expenses for matters relating to environmental control, remediation, monitoring, and compliance. During 2025, we incurred costs related to the monitoring and compliance of environmental matters in the amount of approximately $60.4 million and capital expenditures related to environmental compliance of approximately $10.0 million. Of the costs incurred during 2025 for monitoring and compliance, approximately 72% were related to the normal transportation and disposal of certain types of by-products produced in our steelmaking processes and other facilities in accordance with legal requirements. We incurred combined environmental remediation costs of approximately $9.3 million at all of our facilities during 2025. We have an accrual of $4.4 million recorded for environmental remediation related to our metals recycling operations, $2.6 million related to our idled Minnesota ironmaking operations, and $566,000 related to our steel operations. We believe, apart from our dependence on environmental construction and operating permits for our existing and any future manufacturing facilities, that compliance with current environmental laws and regulations is not likely to have a materially adverse effect on our financial condition, results of operations, or liquidity. However, environmental laws and regulations evolve and change, and we may become subject to more stringent environmental laws and regulations in the future, such as the impact of various governmental legislatures and agencies introducing regulatory changes in response to the potential of climate change.

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

[**Table of Contents**](#TOC)

***Impairments of Long-Lived Tangible and Definite-Lived Intangible Assets.*** We review long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be fully recoverable. Impairment losses are recorded on long-lived assets used in operations when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets' carrying amounts. The impairment loss is measured by comparing the fair value of the asset to its carrying amount. We consider various factors and determine whether an impairment test is necessary, including by way of examples, a significant and prolonged deterioration in operating results and/or projected cash flows, significant changes in the extent or manner in which an asset is used, technological advances with respect to assets which would potentially render them obsolete, our strategy and capital planning, and the economic environment in markets to be served. When determining future cash flows, and, if necessary, fair value, we must make judgments as to the expected utilization of assets and estimated future cash flows related to those assets. We consider historical and anticipated future results, general economic and market conditions, the impact of planned business and operational strategies, and all other available information at the time the estimates are made. Those estimates and judgments may or may not ultimately prove accurate. There were no material indicators of impairment or impairment charges recorded during 2025, 2024, or 2023.

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

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

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

[**Table of Contents**](#TOC)

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

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

Our fourth quarter 2025, 2024, and 2023 annual goodwill impairment analyses did not result in any impairment charges. During 2025 and 2024, we performed a qualitative assessment and performed a quantitative test in 2023. Management does not believe that it is reasonably likely that our reporting units will fail the goodwill impairment test in the near term, given the results of our most recent qualitative assessment and the determined fair value of the reporting units with goodwill from our most recent quantitative test exceeded their carrying value by more than an insignificant amount. Changes in judgments and estimates underlying our analysis of goodwill for possible impairment, including expected future operating cash flows and discount rate, could decrease the estimated fair value of our reporting units in the future and could result in an impairment of goodwill.

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

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

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

In our metals recycling, aluminum, and steel operations, we have certain fixed price contracts with various customers and suppliers for future delivery of nonferrous and ferrous metals. We believe these contracts will be fully consummated. Our risk strategy has been to enter into base metal financial contracts with the goal to protect the profit margin, within certain parameters, that was contemplated when we entered into the transaction with the customer or vendor. At December 31, 2025, we had a cumulative unrealized loss associated with these financial contracts of $56.0 million, substantially all of which have settlement dates in 2026.

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

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

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

We completed the acquisition of the remaining 55% interest in New Process Steel, L.P. (NPS) on December 1, 2025. In conducting our evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2025, we have elected to exclude NPS from our evaluation in the year of acquisition as permitted by the Securities and Exchange Commission. NPS constituted approximately 3% and 5% of the company's total and net assets, respectively, as of December 31, 2025, and 0.4% of the company's net sales for the year then ended.

Under the supervision and with the participation of our management, including our principal executive officer and our principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting. The framework on which such evaluation was based upon is contained in the report entitled "Internal Control—Integrated Framework" issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) (the "COSO criteria"). Based on that evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2025, the end of the period covered by this report.

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

**Definition and Limitations of Internal Control Over Financial Reporting**

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

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

|  | ***Valuation of Goodwill*** |
| *Description of<br>the Matter* | At December 31, 2025, the Company's goodwill was approximately $477 million. As discussed in Note 1 of the consolidated financial statements, the Company performs an impairment test for goodwill at least annually or when indicators of impairment exist. The Company performed a qualitative assessment as of October 1, 2025, to assess if it is more likely than not that the fair value of a reporting unit exceeds its carrying amount.  |
| *Description of<br>the Matter* | Auditing management's annual goodwill impairment test was complex and judgmental as management considers the impact of several factors on the Company overall and each reporting unit individually including assessing the qualitative factors to be considered in the qualitative goodwill impairment assessment, changes in the carrying amount of the reporting unit, macroeconomic conditions (including changes in interest and discount rates), industry and market conditions, recent and projected financial performance, the Company's competitive position and other factors. Significant judgment is involved in evaluating the totality of all factors to determine whether it is more likely than not that the fair value of the reporting unit exceeds its carrying value. |
| *How We<br>Addressed the<br>Matter in Our<br>Audit* | We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company's goodwill impairment testing process, including controls over management's review of the qualitative factors described above. |
| *How We<br>Addressed the<br>Matter in Our<br>Audit* | To test management's conclusion that it is more likely than not that the fair values of the Company's reporting units exceed their carrying amounts, we performed audit procedures that included, among others, assessing the reasonableness of the qualitative factors considered within the analyses, testing the evaluation of the qualitative factors and the underlying data used by the Company in its analyses. We evaluated management's assessment of the qualitative factors for each reporting unit by comparing to current industry and economic trends, current and historical results and key business drivers for each reporting unit, comparing the Company's share price trends to historical amounts, and other relevant factors, including considering consistency with evidence obtained in other parts of the audit and evaluating whether any contrary evidence exists.  |
|  | ***Valuation of Acquired Customer Relationships Intangible Asset***  |
| *Description of<br>the Matter* | As described in Note 2 to the consolidated financial statements, on December 1, 2025, the Company completed the acquisition of the remaining 55% interest in New Process Steel, L.P. for a purchase price of $229 million. The Company measured the assets and liabilities assumed at fair value, which resulted in the recognition of a customer relationships intangible asset of $96 million.  |
| *Description of<br>the Matter* | Auditing the valuation of the acquired customer relationships intangible asset required auditor judgment due to the nature and extent of audit effort in evaluating certain assumptions required to estimate the fair value using a multi-period excess earnings method, which is a specific discounted cash flow method. In particular, the fair value measurement of customer relationships utilized management's forecasts of revenue growth rates and projected margins to estimate the discounted cash flows.  |
| *How We<br>Addressed the<br>Matter in Our<br>Audit* | We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company's process to estimate the fair value of the acquired customer relationships intangible asset, including controls over management's review of the significant assumption described above. |
| *How We<br>Addressed the<br>Matter in Our<br>Audit* | To test the fair value estimate of the customer relationships intangible asset, we performed audit procedures which included, among others, testing the significant assumptions described above, testing the completeness and accuracy of the underlying data, and evaluating the valuation methodology with the assistance of our valuation specialists. We compared the significant assumptions to current industry and economic trends and historical results of the acquired business. We performed sensitivity analyses to evaluate the impact of changes in the significant assumptions to the fair value of the customer relationships intangible asset. |

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

#### Description of the Business
Steel Dynamics, Inc. (SDI), together with its subsidiaries (the company), is a leading industrial metals solutions company, with facilities located throughout the United States and Mexico. SDI is one of the largest domestic steel producers and metal recyclers in North America, 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 has four reporting segments: steel operations, metals recycling operations, steel fabrication operations, and aluminum operations. Approximately 4% of the company's workforce in four locations is represented by collective bargaining agreements, and agreements affecting 0.1% of the company's employees at one location expires during 2026.

#### Steel Operations Segment
Steel operations include the company's electric arc furnace (EAF) steel mills, including Butler Flat Roll Division, Columbus Flat Roll Division, Southwest-Sinton Flat Roll Division, Structural and Rail Division, Engineered Bar Products Division, Roanoke Bar Division, and Steel of West Virginia; steel coating and processing operations at The Techs, Heartland Flat Roll Division, United Steel Supply, New Process Steel, L.P. ("NPS") (acquired December 1, 2025), and Vulcan Threaded Products, Inc.; and warehouse operations in Mexico; and a 75% controlling equity interest in SDI Biocarbon Solutions, LLC.

#### Metals Recycling Operations Segment
Metals recycling operations include the company's Omni ferrous and nonferrous processing, transportation, marketing, brokerage, and scrap management services primarily located throughout the United States and in Central and Northern Mexico.

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

#### Aluminum Operations Segment
Aluminum operations include 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 is a joint venture, of which SDI has a 94.4% controlling equity interest, with Unity Aluminum, Inc. The aluminum flat rolled products mill began operations in the second half of 2025.

#### Other
Other operations consist of subsidiary operations that are below the quantitative thresholds required for reportable segments and primarily consist of a joint venture and the company's idled Minnesota ironmaking operations. Redeemable noncontrolling interests related to Mesabi Nugget (owned 86% by SDI) are $111.2 million at December 31, 2025 and 2024. Also included in "Other" are certain unallocated corporate accounts, such as the company's senior unsecured credit facility, senior notes, certain other investments, and certain profit sharing expenses.

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

#### Summary of Significant Accounting Policies

#### Principles of Consolidation
The consolidated financial statements include the accounts of SDI, together with its wholly- and majority-owned or controlled subsidiaries, after elimination of intercompany accounts and transactions. Noncontrolling and redeemable noncontrolling interests represent the noncontrolling owners' proportionate share in the equity, income, or losses of the company's majority-owned or controlled consolidated subsidiaries.

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

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

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

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

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

#### Note 1. Description of the Business and Summary of Significant Accounting Policies (Continued)
***Credit Losses***

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

At December 31, 2025 and 2024, the company reported $1,682.7 million and $1,417.2 million, respectively, of accounts receivable, net of allowances for credit losses of $5.4 million and $7.7 million, respectively. Changes in the allowance were not significant for the years ended December 31, 2025, 2024, or 2023.

#### Cash and Equivalents, and Restricted Cash
Cash and equivalents include all highly liquid investments with a maturity of three months or less at the date of acquisition. Restricted cash is primarily funds held in escrow as required by various insurance and government organizations. The balance of cash, cash equivalents and restricted cash in the consolidated statements of cash flows includes restricted cash of $5.4 million at December 31, 2025, $5.5 million at December 31, 2024, $5.6 million at December 31, 2023, and $5.5 million at December 31, 2022, which is recorded in Other Assets (noncurrent) in the company's consolidated balance sheets.

#### Short-Term Investments
Short-term investments include investments with maturity dates of longer than three months but less than one year when purchased. The company's short-term investments are classified as trading securities. There were no short-term investments held as of December 31, 2025. Short-term investments held as of December 31, 2024 consisted of commercial paper ($19.7 million), US Treasuries ($113.1 million), and certificates of deposit ($15.0 million). Interest income from invested cash and short-term investments was $36.8 million, $90.1 million, and $111.9 million for the years ended December 31, 2025, 2024, and 2023, respectively, and is recorded in other (income) expense, net as earned.

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

---

| | | |
|:---|:---|:---|

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

#### Property, Plant and Equipment
Property, plant and equipment are stated at cost which includes capitalized interest on construction in progress amounts, and is reduced by proceeds received from certain state and local government grants and other capital cost reimbursements, except for assets acquired in acquisitions which are valued at fair value at the purchase date. The company assigns each fixed asset a useful life ranging from 3 to 15 years for plant, machinery and equipment, and 5 to 40 years for buildings and improvements. Repairs and maintenance are expensed as incurred. Depreciation is provided utilizing the straight-line depreciation methodology, or the units-of-production depreciation methodology for certain production-related steel and aluminum operations segment assets, based on units produced, subject to minimum and maximum levels. Depreciation expense was $515.0 million, $441.2 million, and $397.0 million for the years ended December 31, 2025, 2024, and 2023, respectively.

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **2025** | **2024** | <br>**Useful**<br>**Life** | **Weighted**<br>**Average**<br>**Amortization**<br>**Period** |
| Customer, vendor and scrap generator relationships  | $539505 | $444812 | 8 to 25 years | 23 years |

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

#### Goodwill
The company's goodwill consisted of the following at December 31, 2025 and 2024 (in thousands):

---

| | |
|:---|:---|
| Steel Operations Segment | $272133 |
| Aluminum Operations Segment | 14000 |
| Metals Recycling Operations Segment | 189413 |
| Steel Fabrication Operations Segment  | 1925 |
|  | $477471 |

---

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

[**Table of Contents**](#TOC)

#### Note 1. Description of the Business and Summary of Significant Accounting Policies (Continued)
When conducting a qualitative assessment, the company considers the impact of several factors on the company overall and each reporting unit individually including the timing and results of prior quantitative tests performed, changes in the carrying amount of the reporting unit, macroeconomic conditions (including changes in interest and

discount rates), industry and market conditions, recent and projected financial performance, the company's competitive position and other factors. When conducting a quantitative test, the fair value of the reporting unit is determined by

using an estimate of future cash flows utilizing a risk-adjusted discount rate to calculate the net present value of future cash flows (income approach), and for some years by using a market approach based upon an analysis of valuation metrics of comparable peer companies, using Level 3 fair value inputs as provided for under ASC 820, *Fair Value Measurement*.

No impairment was identified during the company's 2025, 2024 or 2023 annual goodwill impairment analysis. During 2025 and 2024, the company performed a qualitative assessment and performed a quantitative test in 2023.

#### Equity-Based Compensation
***The company has several stock-based employee compensation plans which are more fully described in Note 6. *Equity-Based Incentive Plans*. Compensation expense for restricted stock units, deferred stock units, restricted stock, stock appreciation awards, and performance awards is recorded over the vesting periods using the fair value as determined by the closing market value of the company's common stock on the day prior to grant date, and with respect to performance awards, an estimate of probability of award achievement during the performance period. The company recognizes forfeitures as they occur. Compensation expense for these stock-based employee compensation plans was $66.8 million, $65.6 million, and $60.1 million for the years ended December 31, 2025, 2024, and 2023, respectively.***

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

#### Earnings Per Share
Basic earnings per share is based on the weighted average shares of common stock outstanding during the period. Diluted earnings per share assumes the weighted average dilutive effect of common share equivalents outstanding during the period applied to the company's basic earnings per share. Common share equivalents represent potentially dilutive restricted stock units, deferred stock units, restricted stock, and performance awards, and are excluded from the computation in periods in which they have an anti-dilutive effect. There were 62,000 anti-dilutive common share equivalents for the three-month period ended March 31, 2025 excluded from common share equivalents for the year ended December 31, 2025. There were 269,000 anti-dilutive common share equivalents as of and for the year ended December 31, 2024.

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

#### Derivative Financial Instruments
The company routinely enters into exchange traded futures to manage price risk associated with nonferrous metal inventory, as well as purchases and sales of nonferrous (primarily aluminum and copper) and ferrous metals, to reduce exposure to commodity related price fluctuations. These exchange traded futures contracts meet the definition of derivative financial instruments. The company does not enter into these derivative financial instruments for speculative purposes. The company recognizes all derivatives as either assets or liabilities in the consolidated balance sheets and measures those instruments at fair value. Derivatives that are not designated as cash flow hedges must be adjusted to fair value through earnings. For the effective fair value hedges, the hedged item is recognized on the balance sheet at fair value. Changes in the fair value of the hedged balance sheet item are recognized as an offset against the change in fair value of the derivative in cost of goods sold and included in cash flows from operations. The ineffective portion of a derivative's change in fair value is immediately recognized in earnings for fair value hedges. Changes in the fair value of cash flow hedges are recognized in other comprehensive income, until the hedged item is recognized in earnings.

[**Table of Contents**](#TOC)

#### Note 1. Description of the Business and Summary of Significant Accounting Policies (Continued)
The company offsets fair value amounts recognized for derivative instruments executed with the same counterparty under master netting agreements. The fair value of the company's derivative instruments and required margin deposit totaled $56.2 million and $26.0 million at December 31, 2025 and 2024, respectively, including required margin deposits of $112.2 million and $12.7 million at December 31, 2025 and 2024, respectively, which are reflected in other current assets in the consolidated balance sheets. The fair value of the derivative instruments is disclosed in Note 7. *Fair Value Measurements*. Total gains and losses related to derivatives in fair value hedging relationships, as well as those not designated as hedging instruments, are recognized in costs of goods sold. The company recognized losses of $76.7 million and gains of $11.4 million and $10.0 million for the years ended December 31, 2025, 2024, and 2023, respectively. Derivatives accounted for as cash flow hedges, for which gains and losses are recognized in other comprehensive income, along with net amounts reclassified from accumulated other comprehensive income, were insignificant for the years ended December 31, 2025, 2024, and 2023.

#### Recently Adopted Accounting Pronouncements
In December 2023, the FASB issued ASU 2023-09, *Income Taxes (Topic 740): Improvements to Income Tax Disclosures*, which modifies the rules on income tax disclosures to require entities to disclose specific categories in the rate reconciliation, the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and income tax expense or benefit from continuing operations (separated by federal, state and foreign). The company adopted ASU 2023-09 during the year ended December 31, 2025. See Note 4. *Income Taxes.*

#### Recently Issued Not Yet Adopted Accounting Pronouncements
In November 2024, the FASB issued ASU 2024-03, *Income Statement Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses*, requiring public entitles to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2024-03.

#### Note 2. Business Combinations

#### United Steel Supply
As of December 31, 2024, the company had a 90% controlling interest in United Steel Supply, LLC. On April 1, 2025, a noncontrolling member of USS exercised its option to require SDI to purchase its 5% equity interest, increasing SDI's ownership to 95%. The remaining noncontrolling member has the option to require SDI to purchase, and SDI has the option to acquire, the outstanding 5% equity interest of USS. Redeemable noncontrolling interests related to USS are $30.0 million and $60.0 million at December 31, 2025, and 2024, respectively.

#### New Process Steel, L.P.
On December 1, 2025, the company acquired the remaining 55% equity interest in New Process Steel, L.P., increasing its ownership from 45% to 100% and obtaining control. NPS is a metals solutions and distribution supply-chain management company headquartered in Houston, Texas, with a focus toward growing its value-added manufacturing applications. The acquisition of NPS expands the company's exposure to value-added manufacturing opportunities. Prior to the 2025 acquisition date, the company accounted for its 45% minority equity interest in NPS as an equity-method investment. Upon the acquisition of the remaining interest, the previously held equity interest was remeasured to an acquisition-date fair value of $220.4 million, based on the purchase price of the remaining 55% interest. The company recognized a gain of $6.5 million as a result of remeasuring its prior equity interest in NPS before the business combination, included in other (income) expense, net in the consolidated statements of income for the year ended December 31, 2025.

[**Table of Contents**](#TOC)

#### Note 2. Business Combinations (Continued)

The company is in the process of obtaining third-party valuations of property, plant, and equipment and certain intangible assets. Accordingly, the provisional amounts included above are subject to change during the measurement period. The identifiable intangible assets acquired include customer relationships of $96.3 million and trade names of $35.6 million. The company estimated the provisional amount for the trade name based on a relief from royalty method under the income approach and estimated the provisional amount for the customer relationships based on a multi-period excess earnings method, which is a specific discounted cash flow method under the income approach. The company utilizes an accelerated amortization methodology to follow the pattern in which the economic benefits of the customer relationship intangible asset are anticipated to be consumed over its 25 year assigned life. The company amortized the intangible asset related to the trade name using a straight-line methodology over its 25 year assigned life.

#### Financing Activity
In March 2025, the company issued $600.0 million of 5.250% notes due 2035 and $400.0 million of 5.750% notes due 2055. Proceeds from these notes were used for repayment of the company's $400.0 million of 2.400% notes due 2025 and for other general corporate purposes.

In November 2025, the company issued $650.0 million of 4.000% notes due 2028 and an additional $150.0 million of 5.250% notes due 2035. Proceeds from these notes were used to redeem the company's $400.0 million of 5.000% notes due 2026 and for other general corporate purposes.

#### Senior Credit Facility, due 2028
On July 19, 2023, the company entered into an unsecured credit agreement comprised of a senior unsecured credit facility (Facility), which provides a $1.2 billion unsecured Revolver, maturing July 2028. Subject to certain conditions, the company has the opportunity to increase the Facility size by $500.0 million. The unsecured Facility is available to fund working capital, capital expenditures, and other general corporate purposes. The Facility contains financial covenants and other covenants pertaining to the company's ability to incur indebtedness and permit liens on certain assets. The company's ability to borrow funds within the terms of the unsecured Facility is dependent upon its continued compliance with financial and other covenants. At December 31, 2025, the company had $1.2 billion of availability on the Facility, $9.2 million of outstanding letters of credit and other obligations which reduce availability, and there were no borrowings outstanding.

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

[**Table of Contents**](#TOC)

#### Note 3. Long-Term Debt (Continued)
**The financial covenants under the Facility state that the company must maintain an interest coverage ratio of not less than 2.50:1.00. The company's interest coverage ratio is calculated by dividing its LTM consolidated EBITDA by its LTM gross interest expense, less amortization of financing fees. In addition, a debt to capitalization ratio of not more than 0.60:1.00 must be maintained. At December 31, 2025, the company's interest coverage ratio and debt to capitalization ratio were 13.33:1.00 and 0.32:1.00, respectively. The company was, therefore, in compliance with these covenants at December 31, 2025, and anticipates remaining in compliance during the next twelve months.**

**Certain wholly-owned and controlled subsidiaries of the company file separate federal and state income tax returns. These subsidiaries generated state net operating loss carryforwards, which will expire in the years 2034 through 2045 if not utilized. Annually, the company evaluates the realizability of the net deferred tax assets for this controlled subsidiary. In completing this evaluation, the company considers all available positive and negative evidence in order to determine whether, based on the weight of the evidence, a valuation allowance for its deferred tax assets is necessary. Such evidence includes current operating results, historical results, future reversals of existing taxable temporary differences and expectations for future taxable income (exclusive of the reversal of temporary differences and carryforwards), as well as the implementation of feasible and prudent tax planning strategies. Based on the evidence, the company maintained a valuation allowance of $1,360,000 and $1,150,000 as of December 31, 2025, and 2024, respectively, with respect to certain state tax credits of the controlled subsidiary.**

---

Included in the balance of unrecognized tax benefits at December 31, 2025 and 2024 are potential benefits of $27.2 million and $26.4 million, respectively, that, if recognized, would affect the effective tax rate. The company recognizes interest and penalties related to its tax contingencies on a net-of-tax basis in income tax expense. During the year ended December 31, 2025, the company recognized income from the decrease of interest expense and penalties of $340,000, net of tax. During the years ended December 31, 2024 and 2023, the company recognized expense from the increase of interest expense and penalties of $710,000 and $1,560,000, respectively, net of tax. In addition to the unrecognized tax benefits in the table above, the company had $3.7 million and $4.2 million accrued for the payment of interest and penalties at December 31, 2025 and 2024, respectively.

The company files income tax returns in the U.S. federal jurisdiction as well as income tax returns in various state jurisdictions. The tax years 2022 through 2025 remain open to examination by the Internal Revenue Service and various state and local jurisdictions.

#### Note 5. Shareholders' Equity

#### Cash Dividends
The company declared cash dividends of $294.1 million, or $2.00 per common share, during 2025; $284.1 million, or $1.84 per common share, during 2024; and $280.5 million, or $1.70 per common share, during 2023. The company paid cash dividends of $291.2 million, $282.6 million, and $271.3 million during 2025, 2024, and 2023, respectively.

#### Treasury Stock
In November 2022, the board of directors authorized a share repurchase program of up to $1.5 billion of the company's common stock. This program was exhausted in November 2023. In November 2023, the board of directors authorized an additional share repurchase program of up to $1.5 billion of the company's common stock. This program was exhausted in March 2025. In February 2025, the board of directors authorized an additional share repurchase program of up to $1.5 billion of the company's common stock. Under the share repurchase programs, purchases take place as and when the company determines in open market or private transactions made based upon the market price of the company's common stock, the nature of other investment opportunities or growth projects, the company's cash flows from operations, and general economic conditions. The share repurchase programs do not require the company to acquire any specific number of shares, and may be modified, suspended, extended, or terminated by the company at any time. The share repurchase programs do not have an expiration date. The company repurchased 6.7 million shares for $900.9 million during 2025, 9.4 million shares for $1.2 billion during 2024, and 13.4 million shares for $1.5 billion during 2023 under the share repurchase programs. At December 31, 2025, the company had remaining authorization to repurchase $801.0 million of additional shares under the February 2025 share repurchase program.

#### Note 6. Equity-Based Incentive Plans

#### 2023 Equity Incentive Plan
In May 2023, the company's shareholders approved the 2023 Equity Incentive Plan (2023 Plan), which superseded the prior Amended and Restated 2015 Equity Incentive Plan. The 2023 Plan is designed to attract, motivate, and retain qualified persons that are able to make important contributions to the company's success. To accomplish these objectives, the 2023 Plan provides for awards of equity-based incentives through granting of restricted stock units (RSUs), deferred stock units (DSUs), stock appreciation rights (SARs), performance awards, such as the long-term incentive compensation program (LTIP), restricted stock awards (of which none have been granted), stock options (of which none have been granted), and unrestricted stock awards (of which none have been granted). Under the 2023 Plan, 9.0 million shares of common stock were reserved for grant through December 31, 2033. The 2023 Plan uses a fungible share concept under which any awards that are not a full-value award, such as stock options and stock-settled SARs, will be counted against the share reserve as one share for each share of common stock, and awards that are full-value awards, such as RSUs, DSUs, restricted and unrestricted stock awards, and performance awards, will be counted against the share reserve as 2.09 shares for each share of common stock. The SARs the company has granted to date (of which none are outstanding at December 31, 2025) can only be settled in cash, and thus, do not count against the share reserve. At December 31, 2025, there were 5.1 million shares still available for issuance.

Substantially all of the company's full-time, non-union, U.S. team members receive RSUs, which are granted annually in November at no cost to employees and vest 100% over the shorter of two years from grant date or upon the recipient reaching retirement eligible age (59½ years). During 2025, 2024, and 2023, certain key senior leadership of the company received RSUs in February which vest over a period of 2 to 4 years. The RSUs are converted to stock and issued to employees upon vesting. The company satisfies RSUs with newly issued shares, and satisfies restricted and unrestricted stock awards, DSUs, and performance awards with treasury shares. In addition to the RSUs and LTIP awards granted during the three-year period ended December 31, 2025, presented below, the company awarded 14,000, 13,000 and 18,000 DSUs in 2025, 2024 and 2023, respectively.

#### Restricted Stock Units
A summary of the company's RSU activity and outstanding RSUs as of December 31, 2025, are presented below (dollars in thousands except grant date fair value):

[**Table of Contents**](#TOC)

#### Note 6. Equity-Based Incentive Plans (Continued)
The weighted average remaining life before vesting of the outstanding RSUs as of December 31, 2025, is 1.3 years. The fair value of RSUs vesting during 2025, 2024, and 2023 was $60.7 million, $56.2 million, and $58.3 million, respectively, and were net-share settled such that the company withheld shares with value equivalent to the employees' minimum statutory obligation for the applicable income and other employment taxes and remitted the cash to the appropriate taxing authorities. The total shares withheld in 2025, 2024, and 2023 were approximately 253,000, 287,000, and 342,000 shares, respectively, and were based on the value of the RSUs on their vesting dates as determined by the company's closing stock price.

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

The Compensation Committee granted the following three-year performance period awards and transition awards, which have been earned and have or will be issued as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **Maximum**<br>**Shares That**<br>**Could Be Issued** | <br>**Award**<br>**Earned** | **Award Issued/Issuable** | **Award Issued/Issuable** |

\* Not yet earned as performance period not complete.

#### 2018 Executive Incentive Compensation Plan (2018 Executive Plan)
The 2018 Executive Plan provides for eligibility of certain senior leadership of the company to receive cash and stock bonuses based on predetermined formulas. The company's shareholders approved the 2018 Executive Plan in May 2018 and 2.0 million shares of company stock were reserved for grant through February 28, 2028. At times a portion of the bonus may be distributed in shares of the company's stock, of which one-third of the shares vest immediately and the remaining shares vest in equal annual installments over an additional two-year service-based vesting period requirement. At December 31, 2025, 2024, and 2023, 1.3 million shares under the 2018 Executive Plan remained available for grant. Pursuant to the 2018 Executive Plan, 15,000, 17,000, and 29,000 shares were awarded with a market value of $2.7 million, $2.2 million, and $3.5 million for the 2025, 2024, and 2023 award years, respectively.

[**Table of Contents**](#TOC)

#### Note 7. Fair Value Measurements
Accounting standards provide a comprehensive framework for measuring fair value, sets forth a definition of fair value and establishes a hierarchy prioritizing the inputs to valuation techniques, giving the highest priority to quoted prices in active markets for identical assets and liabilities and the lowest priority to unobservable value inputs. Levels within the hierarchy are defined as follows:

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

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

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

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

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | <br>**Total** | **Quoted Prices**<br> **in Active**<br> **Markets for** <br>**Identical Assets**<br> **(Level 1)** | **Significant** <br>**Other**<br> **Observable** <br>**Inputs**<br>**(Level 2)** | <br>**Significant**<br>**Unobservable**<br>**Inputs**<br>**(Level 3)** |
| **December 31, 2025** |  |  |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Commodity futures – financial assets | $8925 | $- | $8925 | $- |
| &nbsp;&nbsp;&nbsp;&nbsp;Commodity futures – financial liabilities | 64896 | - | 64896 | - |
| **December 31, 2024** |  |  |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Short-term investments | $147811 | $- | $147811 | $- |
| &nbsp;&nbsp;&nbsp;&nbsp;Commodity futures – financial assets | 19323 | - | 19323 | - |
| &nbsp;&nbsp;&nbsp;&nbsp;Commodity futures – financial liabilities | 6272 | - | 6272 | - |

---

The carrying amounts of financial instruments including cash equivalents approximate fair value (Level 1). The fair values of short-term investments commodity futures contracts are estimated by the use of quoted market prices, estimates obtained from brokers, and other appropriate valuation techniques based on references available (Level 2). The fair value of long-term debt, including current maturities, as determined by quoted market prices (Level 2), was approximately $4.1 billion and $3.0 billion at December 31, 2025, and 2024, respectively (with a corresponding carrying amount in the consolidated balance sheet of $4.2 billion and $3.2 billion at December 31, 2025, and 2024, respectively).

#### Note 8. Commitments and Contingencies
The company has entered into certain commitments with suppliers which are of a customary nature. Commitments have been entered into relating to future expected requirements for commodities such as electricity, water, natural gas and its transportation services, fuel, air products, zinc, and electrodes. Certain commitments contain provisions which require that the company "take or pay" for specified quantities at fixed prices without regard to actual usage for periods of generally up to 5 years for physical commodity requirements and commodity transportation requirements, with some extending beyond, and for up to 14 years for air products and 26 years for water products. The company utilized such "take or pay" requirements during the past three years under these contracts. The company believes that production requirements will be such that consumption of the products or services purchased under these commitments will occur in the normal production process.

[**Table of Contents**](#TOC)

#### Note 11. Leases
The company has operating leases relating principally to transportation and other equipment, and some real estate. The company determines if an arrangement contains a lease at inception, which generally occurs when the arrangement identifies a specific asset that the company has the right to direct the use of and obtain substantially all of the economic benefit from use of the identified asset. Certain of the lease agreements contain rent escalation clauses (including fixed and index-based escalations), and options to extend or terminate the lease. For purposes of calculating operating lease obligations, the company's lease terms include options to extend the lease when it is reasonably certain that the company will exercise such option. The company uses its incremental borrowing rate at lease commencement to determine the present value of lease payments. The incremental borrowing rate is the rate of interest the company could borrow on a collateralized basis over a similar term with similar payments. Operating lease expense is recognized on a straight-line basis over the lease term.

#### Note 12. Segment Information
The company's chief operating decision maker (CODM), who is the Chief Executive Officer, analyzes the results of the business through the following reportable segments: steel operations, metals recycling operations, steel fabrication operations, and aluminum operations. The segment operations are more fully described in Note 1. *Description of the Business and Summary of Significant Accounting Policies* to the consolidated financial statements.

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

The company's segment results, including disaggregated revenue by segment to external, external non-United States, and other segment customers, are as follows (in thousands):
