Item 1. — Business

General Overview

Worthington Steel, Inc., an Ohio corporation (“Worthington Steel” and, together with its consolidated subsidiaries and joint ventures, referred to herein as the “Company,” “we,” “us” or “our”) is one of North America’s premier value-added metals processors with the ability to provide a diversified range of products and services that span a variety of end markets. We are a value-added processor of carbon flat-rolled steel and a producer of laser welded solutions and electrical steel laminations. We are one of the largest independent intermediate processors of carbon flat-rolled steel in the U.S. We occupy a niche in the steel industry by focusing on products requiring exact specifications.

We buy coils of steel from primary steel producers and process them to the precise type, thickness, length, width, shape and surface quality required by customer specifications. Our product lines and processing capabilities include:

We also toll process steel for steel mills, large end-users and service centers. Toll processing is different from direct sale steel processing in that the customer retains title to the steel and has the responsibility for selling the end product. Toll processing allows us to earn a fee for services without incurring inventory costs. Our manufacturing facilities further benefit from the flexibility to move between direct versus tolling services based on demand throughout the year.

We operate 34 manufacturing facilities located in the U.S. (19), Canada (2), China, India, Germany, Mexico (4), Italy (3), France, Slovakia, and Switzerland. In addition, our Serviacero joint venture operates three additional manufacturing facilities in Mexico. On June 3, 2026, subsequent to the completion of the fiscal year ended on May 31, 2026 (“fiscal 2026”), through our wholly owned indirect subsidiary Worthington Steel GmbH (the “Bidder”), we acquired a controlling equity stake in Germany-based Klöckner & Co SE (“Kloeckner”), which operates approximately 110 distribution and processing facilities primarily located in the United States, Mexico, Germany, Austria, and Switzerland.

We serviced approximately 1,500 customers during fiscal 2026 in many end markets including automotive, construction, machinery and equipment, agriculture, and heavy trucks, among others. The automotive industry is one of the largest consumers of flat-rolled steel, and the largest end market for us. During fiscal 2026, our top three customers, each of whom is in the automotive industry, represented approximately 34.5% of total net sales. During fiscal 2025, our top three customers represented approximately 33.0% of total net sales.

The steel processing industry is fragmented and highly competitive. There are many competitors, including other independent intermediate processors. Competition is primarily on the basis of price, product quality and the ability to meet delivery requirements. Technical service and support for material testing and customer-specific applications enhance the quality of products (see the Technical Services section below). However, the extent to which technical service and support capability has improved our competitive position has not been quantified. Our ability to meet tight delivery schedules is, in part, based on the proximity of our facilities to customers, suppliers and one another. The extent to which plant location has impacted our competitive position has not been quantified. Processed steel products are priced competitively, primarily based on market factors, including, among other things, market pricing, the cost and availability of raw materials, transportation and shipping costs, and overall economic conditions in the U.S. and abroad.

Our philosophy is rooted in the belief that people are our most important asset and is the basis for our unwavering commitment to our employees, customers, suppliers, and shareholders. Our primary goal is to create value for our shareholders. Built on the successful

foundation of the Worthington Business System, a strategic framework designed to drive continuous improvement through the use of enabling tools and technology that help drive results and inform our business decisions, we apply a disciplined approach to capital deployment and seek to grow earnings by optimizing our operations and supply chain, developing and commercializing new products and applications, and pursuing strategic investments and acquisitions.

On June 3, 2025, we, through our wholly owned subsidiary Tempel Steel Company, LLC (“Tempel”), completed the acquisition of 52% of the issued and outstanding capital stock of S.I.T.E.M. S.p.A., a joint stock company incorporated under the laws of Italy (“Sitem” and, together with its subsidiaries, Stanzwerk AG, Decoup S.A.S. and Sitem Slovakia spol. s r.o., the “Sitem Group”). The results of Sitem Group are included in our consolidated and combined financial statements on a one-month reporting lag to allow for the timely completion of its financial reporting process. For additional information, see “Note 2 – Acquisitions”.

We own a controlling interest in four consolidated operating joint ventures: Spartan Steel Coating, L.We own a controlling interest in three consolidated operating joint ventures: Spartan Steel Coating, L. L.C. (“Spartan”) (52% interest); TWB Company, L. (“Spartan”); TWB Company, L. L.C. (“TWB”) (55% interest); Worthington Samuel Coil Processing, L. (“TWB”); and Worthington Samuel Coil Processing, L. L.C. (“WSCP”) (63% interest); and the Sitem Group (52% interest). We own a noncontrolling interest (50% interest) in one unconsolidated joint venture, Serviacero Planos, S. de R.L. de C.V. (“Serviacero Worthington”) (see the Our Joint Ventures section below). We also own a controlling interest in Worthington Specialty Processing (“WSP”), which became a non-operating joint venture on October 31, 2022.

Our fiscal year and fourth quarter end on May 31, with “fiscal 2026” ending on May 31, 2026, “fiscal 2025” ending on May 31, 2025, and “fiscal 2024” ending on May 31, 2024. Our other quarterly periods end on the final day of August (first quarter), November (second quarter) and February (third quarter).

We are headquartered at 100 West Old Wilson Bridge Road, Columbus, Ohio 43085, telephone (614) 840-3462. The common shares of Worthington Steel (the “common shares”) are traded on the New York Stock Exchange (“NYSE”) under the symbol WS. We maintain a website at www.worthingtonsteel.com.

Recent Business Developments

Segment

Our operations are managed principally on a products and services basis under a single group organizational structure. We determined that there is only one operating segment and therefore one reportable segment after considering several sources of information, including our internal organizational structure, the basis on which budgets and forecasts are prepared, the financial information that our Chief Operating Decision Maker (“CODM”) reviews in evaluating company performance and determining how resources should be allocated, and how we release information to the public and analysts. Our CODM is Worthington Steel’s Chief Executive Officer (“CEO”).

The Separation

On December 1, 2023 (the “Separation Date”) at 12:01 a.m. Eastern Time, Worthington Enterprises, Inc., an Ohio corporation formerly known as Worthington Industries, Inc. (“Worthington Enterprises” or “Former Parent”), completed the separation of its steel processing business into Worthington Steel as a stand-alone, publicly traded company (the “Separation”). (“Worthington Enterprises” or “Former Parent”), completed the Separation into Worthington Steel as a stand-alone publicly traded company. The Separation was achieved through a tax-free pro rata distribution of 100% of the common shares of Worthington Steel to holders of record of Worthington Enterprises common shares (the “Distribution”) as of the close of business on November 21, 2023 (the “Record Date”). Each holder of record of Worthington Enterprises common shares received one common share of Worthington Steel for every one Worthington Enterprises common share held at the close of business on the Record Date. Worthington Enterprises retained no ownership interest in Worthington Steel following the Separation. In connection with the Separation, Worthington Steel entered into several agreements with Worthington Enterprises that govern the relationship between the parties following the Distribution, including a Separation and Distribution Agreement, Tax Matters Agreement, Employee Matters Agreement, Steel Supply and Services Agreement, and Transition Services Agreement.

Sources and Availability of Raw Materials

We have developed strong relationships with our mill suppliers, who provide the quality materials we need, meet our quality and service requirements, and are able to offer competitive terms with regard to quality, pricing, delivery, and volumes purchased.

The primary raw material we purchase is flat-rolled steel. We purchase steel in large quantities at regular intervals from major steel mills, both domestic and foreign. The amount purchased from any supplier varies from year to year depending on a number of factors including market conditions, then-current relationships and prices and terms offered. In nearly all market conditions, steel is available from multiple suppliers and generally any supplier relationship or contract can be, and historically have been, replaced with little or no significant interruption to our business. In nearly all market conditions, steel is available from multiple suppliers and generally any supplier relationship or contract can and has been replaced with little or no significant interruption to our business. During fiscal 2026, we purchased approximately 2.57 million tons of steel (69% hot-rolled, 19% cold-rolled and 12% galvanized). During fiscal 2025, we purchased approximately 2.44 million tons of steel (70% hot-rolled, 20% cold-rolled and 10% galvanized).

Steel is primarily purchased and processed based on specific customer orders. Raw materials are generally purchased in the open market on a negotiated basis. Supply contracts are also entered into, some of which have fixed pricing and some of which are indexed (monthly or quarterly). During fiscal 2026, we purchased steel from the following major suppliers, in alphabetical order: Cleveland-Cliffs Steel Inc.; NLMK Indiana LLC; North Star BlueScope Steel, LLC; Nucor Corporation; Steel Dynamics, Inc.; NLMK Indiana LLC; North Star BlueScope Steel, LLC; Nucor Corporation; Steel Dynamics, Inc; and United States Steel Corporation. ; and United States Steel Corporation.

For certain raw materials, such as zinc, there are limited suppliers and our purchases are generally at market prices. However, historically, we have been able to replace our supplier relationships or contracts with little or no significant interruption to our business. Major suppliers of zinc in fiscal 2026 were, in alphabetical order: Glencore Ltd; Nexa Resources US Inc.; Ritchey Metals Company Inc.; Teck Resources Limited; and Trafigura Trading LLC. We believe our supplier relationships are generally favorable.

Seasonality

Our operations have historically been subject to seasonal fluctuations that may impact our cash flows for a particular period. Our sales are generally strongest in the fourth quarter of the fiscal year when our business is normally operating at seasonal peaks, and our sales

are generally weakest in the third quarter of the fiscal year, primarily due to reduced activity in the construction industry as a result of the colder, more inclement weather, as well as customer plant shutdowns in the automotive industry due to holidays.

Our Joint Ventures

As part of our strategy to selectively develop new products, markets, and processing capabilities and to expand our international presence, while sharing the risks and costs associated with those activities, we participate in five operating joint ventures. The following four joint ventures are consolidated due to our ability to control operating and capital decisions made in the ordinary course of business:

Our remaining operating joint venture, Serviacero Worthington, in which we own a 50% noncontrolling interest, is unconsolidated and operates three steel processing facilities located in Mexico. Serviacero Worthington provides steel processing services, such as pickling, blanking, slitting, multi-blanking and cutting-to-length, to customers in a variety of industries throughout North America, including automotive, appliance and heavy equipment. Serviacero Worthington has no fixed duration, and its operations shall continue to exist with the consent of the partners and may be extended indefinitely as mutually agreed. Serviacero Worthington is managed by a board of managers consisting of six managers, of which we are entitled to appoint three.

See “Note 4 – Investments” for additional information about our unconsolidated joint venture.See “Note 3 – Investment in Unconsolidated Affiliate” for additional information about our unconsolidated joint ventures.

Environmental Matters

Our manufacturing facilities, like those of similar industries making similar products, are subject to many federal, state, local and foreign laws and regulations, including those relating to the protection of our employees and the environment. In addition to the requirements of the state and local governments of the communities in which we operate, we must comply with federal environmental regulations, the most significant of which are enforced by the EPA. We evaluate and implement ways to reduce emissions and waste and decrease costs related to compliance with environmental and other government regulations. The cost of such activities, compliance or capital expenditures for environmental control facilities necessary to meet regulatory requirements are not estimable, but have not been, and are not anticipated to be, material when compared with our overall costs and capital expenditures and, accordingly, are not anticipated to have a material effect on our financial position, results of operations, cash flows, capital expenditures, earnings or competitive position. The cost of such activities, compliance or capital expenditures for environmental control facilities necessary to meet regulatory requirements are not estimable but have not and are not anticipated to be material when compared with our overall costs and capital expenditures and, accordingly, are not anticipated to have a material effect on our financial position, results of operations, cash flows, capital expenditures, earnings or competitive position.

Twenty-seven of our facilities hold the ISO 14001 certifications, a highly recognized global standard for an effective environmental management system and our remaining facilities are managed to similar standards.Twenty-two of our facilities hold the ISO 14001 certifications, a highly recognized global standard for an effective environmental management system and our remaining facilities are managed to similar standards.

Intellectual Property and Licenses

We own several patents, trademarks, copyrights and trade secrets, and hold licenses to intellectual property owned by others. Although our patents, copyrights, trademarks, trade secrets, and other intellectual property rights are important to our success, we do not consider any single, or in the aggregate, patent, trademark, copyright, trade secret or license to be of material importance to our business.

Corporate Responsibility

Human Capital Management

Our commitment to social governance and sustainability includes putting people first by providing a supportive and inclusive environment built on a culture of engagement, and by working together to ensure the health and safety of our employees. At the corporate level, we maintain a fully dedicated department responsible for environmental, health and safety initiatives and best practices across the Company. At the corporate level, we maintain a fully dedicated department responsible for best-in-class environmental, health and safety initiatives and best practices across the Company.

We focus on attracting, developing and retaining a skilled workforce to support our manufacturing operations and long-term growth. To that end, management emphasizes competitive compensation and benefits, safety and wellness, employee training and development, and leadership succession planning. We also monitor workforce-related indicators such as training participation, internal advancement, turnover and employee engagement to assess the effectiveness of our human capital programs.

As of May 31, 2026, we had approximately 5,400 employees and our unconsolidated joint venture employed approximately 500 additional individuals. Of the aggregate of those groups, approximately 19% of those individuals are represented by collective bargaining units, all of which are located outside of the United States and in jurisdictions where collective bargaining arrangements are customary. We believe that our open-door policy has created an environment which fosters open communication and serves to cultivate the good relationships we have with our employees, including those covered by collective bargaining units.

In line with our people-first philosophy, our employees have always been, and will always be, our most important asset. We operate under a set of core values that are rooted in our long-standing philosophy, which emphasizes the Golden Rule. These core values guide us as a company, including in our approach to people management. As such, we are continually focused on creating and maintaining a strong culture. Our culture provides employees with opportunities for personal and professional development, as well as community engagement, all of which we believe contribute to our overall success. We have repeatedly been recognized as a top place to work and believe we offer our employees competitive pay and benefits, as compared to others in our industry, all while focusing on safety, wellness, and promoting a diverse and inclusive culture.

Safety, Health and Wellness

We have always made the safety and well-being of our people a top priority, and we have regularly maintained an industry-leading safety record. For us, safety is about engagement, and our employees have adopted a culture where safety is everyone’s responsibility, not just the safety of our employees, but for the safety of everyone who enters our facilities. We also provide our employees and their families with access to what we believe are market competitive benefits, as compared to others in our industry, including a parental leave benefit that offers all new parents the opportunity for paid time off. We have a broad array of other employee-centered benefits and wellness programs, including fitness centers, free health screenings, health fairs, and other company-wide and location-specific wellness events and challenges. We believe our investments in safety, health and wellness are key to supporting and protecting our most important asset, our people.

In addition to the requirements of the state and local governments of the communities in which we operate, we must comply with federal health and safety regulations, the most significant of which are enforced by the Occupational Safety and Health Administration (“OSHA”). We comply with and work to exceed all applicable worker safety regulations in the U.S. as governed by OSHA. Our U.S. facilities also hold certifications with various industry groups that require regular inspections including ISO. Our global sites meet or exceed all local regulations for worker safety and hold various accreditations, certifications, and registrations that require regular inspections.

Nineteen of our facilities hold ISO 45001 certifications, a highly recognized global standard for an effective Health and Safety Management System and our remaining facilities are managed to similar standards.Fifteen of our facilities hold ISO 45001 certifications, a highly recognized global standard for an effective Health and Safety Management System and our remaining facilities are managed to similar standards.

Diversity, Equity and Inclusion

Item 1A. — Risk Factors

Summary of Risk Factors

We and our shareholders are subject to a number of risks, including risks related to our business operations, risks related to the Kloeckner Acquisition, risks related to owning our common shares and other general risks. The following is a summary of the material risks we and our shareholders face and is not exhaustive. Please read the full “Risk Factors” discussion that follows this summary carefully for a more thorough description of these and other risks.

Risks Related to Our Business

Risks Related to the Kloeckner Acquisition

Risks Related to the Separation and Our Relationship with the Former Parent

Risks Related to Owning Our Common Shares

General Risk Factors

Risk Factors

Our future results and the market price for the common shares are subject to numerous risks, many of which are driven by factors that we cannot control or predict. The following discussion, as well as other sections of this Form 10-K, including “PART II—Item 7. — Management’s Discussion and Analysis of Financial Condition and Results of Operations,” describe certain risks to our business, our results, our strategies and the common shares. Consideration should be given to the risk factors described below as well as those in the “Cautionary Note Regarding Forward-Looking Statements” section at the beginning of this Form 10-K, in conjunction with reviewing the forward-looking statements and other information contained in this Form 10-K. The risks described below are those that we have identified as material but are not the only risks and uncertainties facing us. Our business is also subject to general risks and uncertainties that affect many other companies, such as market conditions, economic conditions, geopolitical events, changes in laws, rules, regulations or accounting rules, fluctuations in interest rates, terrorism, war or conflicts, major health concerns, natural disasters or other disruptions of expected business conditions. Additional risks and uncertainties not currently known to us or that we currently believe are immaterial also may impair our business, including our results of operations, liquidity and financial condition.

Risks Related to Our Business

Economic or Industry Downturns and Weakness

Our net sales are heavily concentrated in the automotive and construction end markets, and a decline in those end markets may have an adverse impact on our results of operations and cash flows. The automotive and construction industries account for approximately 55.0% and 10.0%, respectively, of our net sales, and reduced demand from these industries could adversely affect our business. An overall downturn in the general economy and/or in the countries in which we conduct business, a disruption in capital and credit markets, persistent inflation, elevated or volatile interest rates, fluctuations in industrial production, high unemployment, reduced consumer confidence or other factors could cause reductions in demand from our end markets in general and, in particular, the automotive and construction end markets. An overall downturn in the general economy and/or in the countries in which we conduct business, a disruption in capital and credit markets, high inflation, high unemployment, reduced consumer confidence or other factors could cause reductions in demand from our end markets in general and, in particular, the automotive and construction end markets. In addition, changes in customer inventory levels, sourcing strategies, build schedules or purchasing patterns may cause demand for our products to fluctuate in ways that are difficult to predict. If demand for the products we sell to the end markets which we supply were to be reduced, our financial results and cash flows could be negatively affected. If demand for the products we sell to the automotive, construction or other end markets which we supply were to be reduced, our financial results and cash flows could be negatively affected.

Financial difficulties and bankruptcy filings by our customers could have an adverse impact on our business. In past years, some customers have experienced, and some continue to experience, challenging financial conditions, whether due to macroeconomic uncertainty, inflationary pressures, elevated borrowing costs, supply chain disruptions, geopolitical instability, increased competition, or otherwise. In past years, some customers have experienced, and some continue to experience, challenging financial conditions, whether due to a public health emergency, the war in Ukraine, inflationary pressures, increased competition, or otherwise. The financial difficulties of certain customers and/or their failure to obtain credit or otherwise improve their overall financial condition could result in changes within the markets we serve, including plant closings, decreased production, reduced demand, changes in product mix, unfavorable changes in the prices, terms or conditions we are able to obtain and other changes that may result in decreased purchases from us and otherwise negatively impact our business. These conditions also increase the risk that our customers may delay or default on their payment obligations to us. If the general economy or any of our markets decline, the risk of bankruptcy filings by and financial difficulties of our customers may increase. While we have taken and will continue to take steps intended to mitigate the impact of financial difficulties and potential bankruptcy filings by our customers, these matters could have a negative impact on our business.

Raw Material Pricing and Availability

Our operating results may be adversely affected by continued volatility in steel prices. Over the past few years, we have experienced volatility in steel prices due to supplier consolidation, changing global supply and demand dynamics, trade policy developments, capacity rationalization and macroeconomic conditions. If steel or other raw material prices were to decrease, competitive conditions or contractual obligations may impact how quickly we must reduce our prices to our customers, and we could be forced to use higher-priced raw materials on hand to complete orders for which the selling prices have decreased, which results in inventory holding losses. Decreasing steel prices could also require us to write-down the value of our inventory to reflect current net realizable value.

Our operating results may be affected by fluctuations in raw material prices and our ability to pass on increases in raw material costs to our customers. Our principal raw material is flat-rolled steel, which we purchase from multiple primary steel producers. The steel industry as a whole has been cyclical, and at times availability and pricing can be volatile due to a number of factors beyond our control. These factors include general economic conditions, domestic and worldwide supply and demand, persistent inflation, the influence of hedge funds and other investment funds participating in commodity markets, curtailed production from major suppliers due to factors such as the closing or idling of facilities, public health emergencies, international conflicts, accidents or equipment breakdowns, repairs or catastrophic events, labor costs, shortages, strikes or other problems, competition, new laws and regulations, import duties, tariffs, energy costs, availability and cost of steel inputs (e. These factors include general economic conditions, domestic and worldwide supply and demand, high inflation, the influence of hedge funds and other investment funds participating in commodity markets, curtailed production from major suppliers due to factors such as the closing or idling of facilities, public health emergencies, international conflicts, accidents or equipment breakdowns, repairs or catastrophic events, labor costs, shortages, strikes or other problems, competition, new laws and regulations, import duties, tariffs, energy costs, availability and cost of steel inputs (e. g., ore, scrap, coke and energy), foreign currency exchange rates and other factors described in the immediately following paragraph. This volatility, as well as any increases in raw material costs, could significantly affect our steel costs and adversely impact our financial results. To manage our exposure to market risk, where possible, we match our customer pricing terms to the pricing terms offered to us by our suppliers in order to minimize the impact of market fluctuations on our

margins. However, should our suppliers increase the prices of our critical raw materials, we may not have alternative sources of supply. In addition, in an environment of increasing prices for steel and other raw materials, competitive conditions or contractual obligations may impact how much of the price increases we can pass on to our customers. In addition, in an environment of increasing prices for steel and other raw materials, competitive conditions or contractual obligations may 6 Table of Contents impact how much of the price increases we can pass on to our customers. To the extent we are unable to pass on future price increases in our raw materials to our customers, our financial results could be adversely affected.

The costs of manufacturing our products and/or our ability to meet our customers’ demands could be negatively impacted if we experience interruptions in deliveries of needed raw materials or supplies. If, for any reason, our supply of flat-rolled steel (including electrical steel) or other key raw materials, such as zinc, or other supplies is curtailed or we are otherwise unable to obtain the quantities we need at competitive prices, our business could suffer and our financial results could be adversely affected. Such interruptions could result from a number of factors, including a shortage of capacity in the supplier base of raw materials, energy or the inputs needed to make steel or other supplies, a failure of suppliers to fulfill their supply or delivery obligations, financial difficulties of suppliers resulting in the closing or idling of supplier facilities, transportation or logistics disruptions, significant weather events, those factors listed in the immediately preceding paragraph or other factors beyond our control. Further, the number of domestic suppliers has decreased in recent years due to industry consolidation and the financial difficulties of certain suppliers, and this consolidation may continue.

An increase in the spread between the price of steel and steel scrap prices can have a negative impact on our margins. An increase in the spread between the price of steel and steel scrap prices can have a negative impact on our margins. No matter how efficient, our operations, which use steel as a raw material, create some amount of scrap. The expected price of scrap compared to the price of the steel raw material is factored into pricing. Generally, as the price of steel increases, the price of scrap increases by a similar amount. When increases in scrap prices do not keep pace with the increases in the price of the steel raw material, due to market dislocations or changes in supply and demand dynamics, it can have a negative impact on our margins. When increases in scrap prices do not keep pace with the increases in the price of the steel raw material, due to events such as a public health emergency or the war in Ukraine, it can have a negative impact on our margins.

Excess Capacity and Over-Production by Foreign Steel Producers or Decreases in Tariffs

Global steel-making capacity may exceed demand for steel products in some regions around the world. Rather than reducing employment by rationalizing capacity with consumption, we believe steel manufacturers in certain countries, sometimes supported by government subsidies or other incentives, have periodically exported steel at prices which may not reflect their costs of production or capital. Excessive imports of steel into the U.S. have exerted, and may continue to exert, downward pressure on U.S. steel prices.

On February 1, 2025, President Trump issued executive orders imposing additional tariffs on imports from Canada, Mexico, and China (a 10% duty on Chinese imports and deferred action on Canada/Mexico) followed by retaliatory tariffs from China. On February 10, 2025, new Section 232 measures reinstated a blanket 25% tariff on all steel imports and raised aluminum tariffs from 10% to 25%, effective March 12, 2025, revoking prior country-specific exemptions and halting product exclusions.

On June 3, 2025, President Trump elevated these tariffs under Section 232 once again by signing a proclamation doubling the steel and aluminum duties to 50%, effective June 4, 2025. This escalation applies broadly to origin-based tariffs (steel, aluminum and derivatives), closes previously negotiated quotas and carve-outs (subject to limited U.K. exceptions until July 9, 2025), and eliminates stacking exceptions with other reciprocal tariffs. On April 6, 2026, U.S. Customs and Border Protection announced implementation changes to Section 232 collection, including application to the full customs value and refinements to how derivative products are treated. These measures have increased the total landed cost of imported metals and have contributed to heightened price volatility in the domestic market.

We expect that these tariffs, while in effect, will discourage steel imports from non-exempt countries. We expect that these tariffs, while in effect, will discourage steel imports from non-exempt countries. If these or other tariffs or duties expire or if others are relaxed or repealed, or if relatively higher U.S. metal prices make it attractive for foreign metal producers to export their products to the U.S., despite the presence of duties or tariffs, the resurgence of substantial imports of foreign metal could create downward pressure on U.S. metal prices. If the Section 232 measures are removed or substantially lessened, whether through legal challenge, legislation, executive action or otherwise, imports of foreign metals could increase and metal prices in the U.S. could fall, which could materially adversely affect our financial results.

Climate change

Concern about climate change might result in new legal and regulatory requirements to reduce or mitigate the effects of climate change. While we believe our operations do not emit significant amounts of carbon dioxide or other greenhouse gases, legal or regulatory changes related to climate change may result in higher prices for metal, higher prices for utilities required to run our facilities, higher fuel costs for us and our suppliers, increased compliance costs and other adverse impacts. We are actively working to support the legislated requirements in multiple jurisdictions including the Corporate Sustainability Reporting Directive and the Carbon Border Adjustment Mechanism in the European Union and California’s Climate Corporate Data Accountability Act and Climate-Related Financial Risk Act. These laws and regulations have, and will continue to have, the potential to impact our operations directly or indirectly as a result of required compliance by us and our suppliers.

There is a focus by governmental and non-governmental entities on sustainability matters. Any perception that we have failed to act responsibly regarding climate change could result in negative publicity and adversely affect our business and reputation.

There also has been stakeholder focus, including by governmental authorities, investors, customers, media and nongovernmental organizations, on environmental sustainability matters, such as climate change, the reduction of greenhouse gases and water consumption. Legislative, regulatory or other efforts to combat climate change or other environmental concerns could result in future increases in taxes, restrictions on or increases in the costs of supplies, transportation and utilities, any of which could increase our operating costs, and necessitate future investments in facilities and equipment. Further, our customers may impose emissions reduction or other environmental standards and requirements. As a result, we may experience increased compliance burdens and the sourcing of our products may be adversely affected. These risks also include the increased pressure to make commitments, set targets, or establish additional goals to take actions to meet them, which could expose us to market, operational, execution and reputational costs or risks. Emerging regulatory frameworks, including carbon pricing mechanisms and border adjustment measures in jurisdictions in which we operate, into which we export, or purchase components and raw materials may affect the competitiveness of our products and increase administrative and compliance complexity.

Developing and acting on initiatives within the scope of social and environmental sustainability, and collecting, measuring and reporting environmental sustainability-related information and metrics can be costly, difficult and time consuming and is subject to evolving reporting standards. Developing and acting on initiatives within the scope of social and environmental sustainability, and collecting, measuring and reporting environmental sustainability-related information and metrics can be costly, difficult and time consuming and is subject to evolving reporting standards. Further, statements about our social and environmental sustainability-related initiatives and goals, and progress against those goals, may be based on standards for measuring progress that are still developing, internal controls and processes that continue to evolve, and assumptions that are subject to change in the future. If our social and environmental sustainability-related data, processes and reporting are incomplete or inaccurate, or if we fail to achieve progress with respect to our goals within the scope of social and environmental sustainability on a timely basis, or at all, our reputation, business, financial performance and growth could be adversely affected. Changing market dynamics, global policy developments, customer decarbonization expectations, and the increasing frequency or severity of extreme weather events affecting critical infrastructure may disrupt our operations, our supply chain, the operations of our customers or suppliers, or increase the costs required to maintain or resume operations.

Inventories

Our business could be harmed if we fail to maintain proper inventory levels. We are required to maintain sufficient inventories to accommodate the needs of our customers including, in many cases, short lead times and just-in-time delivery requirements. Although we typically have customer orders in hand prior to placement of our raw material orders, we anticipate and forecast customer demand. We purchase raw materials on a regular basis in an effort to maintain our inventory at levels that we believe are sufficient to satisfy the anticipated needs of our customers based upon orders, customer volume expectations, historic buying practices and market conditions. Inventory levels in excess of customer demand may result in the use of higher-priced inventory to fill orders reflecting lower selling prices, if raw material prices have significantly decreased. For example, if steel prices decrease, we could be forced to use higher-priced steel than on hand to complete orders for which the selling price has decreased. These events could adversely affect our financial results. Conversely, if we underestimate demand for our products or if our suppliers fail to supply a sufficient quantity of quality products in a timely manner, we may experience inventory shortages. Inventory shortages could result in unfilled orders, negatively impacting our customer relationships and resulting in lost revenues, which could harm our business and adversely affect our financial results.

Customers and Suppliers

The loss of significant volume from our key customers could adversely affect us. A significant loss of, or decrease in, business from any of our key customers could have an adverse effect on our sales and financial results if we cannot obtain replacement business. Also, our sales may be increasingly sensitive to deterioration in the financial condition of, or other adverse developments with respect to, one or more of our top customers. We generally do not have long-term contracts with our customers. As a result, although our customers periodically provide notice of their future product needs and purchases, they generally purchase our products on an order-by-order basis, and the relationship, as well as particular orders, can be terminated at any time.

Many of our key end markets, such as automotive and construction, are cyclical in nature. Cyclical markets can be impacted by both market demand and raw material supply, particularly with respect to steel. The demand for our products is directly related to, and quickly impacted by, customer demand in our end markets, which can change as the result of changes in the general U.S. or worldwide economies and other factors beyond our control. Adverse changes in demand or pricing can have a negative effect on our business and results of operations.

We are unable to predict the duration of the current economic conditions or the magnitude or timing of changes in economic activities, which could adversely affect our customers and, in turn, our business. Our business depends on demand from customers across various end markets, including automotive, construction, and manufacturing. Demand in these markets can be impacted by changes in domestic and global economic conditions, supply chain disruptions, or shifts in trade policy, including the imposition of or changes to tariffs and trade barriers. Recent escalations in U.S. trade measures—including the reinstatement and increase of tariffs under Section 232—have

led to heightened uncertainty in customer sourcing strategies, build schedules, and order patterns, particularly in the automotive sector. This uncertainty has made it difficult to anticipate future customer requirements, which could result in fluctuations in our volumes, operating rates, and financial performance. The magnitude, timing and duration of these economic and policy-driven shifts are uncertain and could continue to adversely affect our results of operations, cash flows and financial condition. While we monitor market developments, the pace, timing, and extent of economic improvement remains uncertain and are outside of our control.

Significant reductions in sales to any of the Detroit Three automakers, or to our automotive-related customers in general, could have a negative impact on our business. 8 Table of Contents Significant reductions in sales to any of the Detroit Three automakers, or to our automotive-related customers in general, could have a negative impact on our business. For fiscal 2026, approximately 55% of our net sales were to automotive-related customers. Although we do sell to the domestic operations of foreign automakers and their suppliers, a significant portion of our automotive sales are to the Detroit Three automakers and their suppliers. A reduction in sales for any of the Detroit Three automakers, as well as additional or prolonged idling of production facilities in response to supply chain constraints, has negatively impacted and could continue to negatively impact our business. In addition, some automakers have begun using greater amounts of aluminum and smaller proportions of steel in some new models, thereby reducing the demand for certain of our products.

Any future United Auto Workers (“UAW”) strikes against the Detroit Three automakers could have material adverse effects on our business, financial position, results of operations and cash flows. The automotive industry is one of the largest consumers of flat-rolled steel, and our largest end market. While the duration and scope of any future UAW strikes against the Detroit Three automakers, as well as the corresponding impact on the business of suppliers to the Detroit Three automakers and the impact on our own business, financial position, results of operations and cash flow, are impossible to predict at this time, the prolonged idling of our customers’ production facilities in response to strikes could have a material adverse impact on us. The UAW strike in our fiscal 2024 had minimal impact on our business due to the limited duration and scope of the strike and our ability to plan accordingly. The extent to which future UAW strikes will impact us will depend on future developments, which cannot be predicted and are highly uncertain. The ultimate impact on our business, financial position, results of operations and cash flows will depend on factors beyond our control including the duration and scope of the strikes.

The closing, idling or relocation of our customers’ facilities could adversely affect us. Our ability to meet delivery requirements and the overall cost of our products as delivered to customer facilities are important competitive factors. If customers close or move their production facilities further away from our manufacturing facilities that supply them, it could have an adverse effect on our ability to meet competitive conditions, which could result in the loss of sales. If customers close or move their production facilities further away from our manufacturing facilities which can supply them, it could have an adverse effect on our ability to meet competitive conditions, which could result in the loss of sales. Likewise, if customers move their production facilities outside the U.S., it could result in the loss of potential sales for us. If customers idle their facilities, it may reduce or delay our sales, resulting in a negative impact on our results of operations and financial condition.

Strikes, work stoppages or other labor disruptions affecting steel mills or other suppliers could have material adverse effects on our business. Certain collective bargaining agreements covering employees represented by the United Steelworkers (“USW”) at several steel mill suppliers expire on September 1, 2026, and these suppliers and the USW may not reach successor agreements before the current agreements expire. Any resulting strike, work stoppage, or other labor disruption could reduce or delay the production and delivery of steel to us, increase our raw material costs, or require us to obtain steel from alternative sources, which may not be available in sufficient quantities, on acceptable terms or in time to meet our production requirements and customer delivery schedules. The duration and scope of any such disruption, as well as the corresponding impact on our business, financial position, results of operations and cash flows, are impossible to predict and will depend on factors beyond our control, including our ability to obtain steel from alternative suppliers.

The closing, idling or relocation of our suppliers’ manufacturing facilities could have a negative impact on us. The closing, idling or relocation of our suppliers’ manufacturing facilities could have a negative impact on us. If delivery from a supplier is disrupted, particularly with respect to certain types of specialty steel, it may be more difficult to obtain an alternate supply than in the past. These closures and disruptions could also have an adverse effect on our suppliers’ on-time delivery performance, which could have an adverse effect on our ability to meet our own delivery commitments and may have other adverse effects on our business. If suppliers relocate their manufacturing facilities farther from our locations, it may result in increased costs to us and/or reduced availability of key supplies which could have a negative impact on our results of operations and financial condition.

Sales conflicts with our customers and/or suppliers may adversely impact us. In some instances, we may compete with one or more of our customers and/or suppliers in pursuing the same business. Such conflicts may strain our relationships with the parties involved, which could adversely affect our future business with them.

The loss of key supplier relationships could adversely affect us. Over the years, we have developed relationships with certain steel and other suppliers which have been beneficial to us by providing more assured delivery and a more favorable all-in cost. If any of those relationships were disrupted, it could have an adverse effect on delivery times and the overall cost, quality and availability of our products or raw materials, which could have a negative impact on our business. In addition, we do not have long-term contracts with any of our suppliers. If we are unable to obtain sufficient amounts of steel and other materials at competitive prices and on a timely basis from our traditional suppliers, we may be unable to obtain these materials from alternative sources at competitive prices to meet our delivery schedules, which could have a material adverse impact on our results of operations. In certain cases, the number of available suppliers for specific products or grades may be limited, which could increase our exposure to supply disruptions or pricing pressure. We rely on suppliers for certain product specifications and quality certifications, and any failure of supplied materials to meet required specifications could adversely affect our business. If materials supplied to us do not conform to applicable specifications or customer requirements, we could experience production delays, customer claims, reputational harm or increased costs.

The U.S. federal government has imposed tariffs on certain foreign goods, including on certain steel products imported into the U.S. and those tariffs may adversely impact our business and financial condition. Although such steel tariffs may benefit portions of our business, these tariffs, as well as country-specific or product-specific exemptions, may also lead to steel price fluctuations and retaliatory actions from foreign governments and/or modifications to the purchasing patterns of our customers that could adversely affect our business or the steel industry as a whole. In particular, certain foreign governments, including Canada, China and Mexico, have instituted or are considering imposing tariffs on certain U.S. goods, which previously contributed to increased raw material prices, but did not have a significant or recurring impact on our business. Restrictions on trade with foreign countries, imposition of customs duties or further modifications to U.S. international trade policy have the potential to disrupt our supply chain or the supply chains of our customers and to adversely impact demand for our products, our costs, customers, suppliers and/or the U.S. economy or certain sectors thereof, potentially leading to negative effects on our business and financial condition.

Competition

Our business is highly competitive, and increased competition may cause decreased demand, decreased market share and/or reduced prices for our products and services and could negatively impact our financial results. Generally, the markets in which we conduct business are highly competitive. Our competitors include a variety of domestic and foreign companies in all major markets. Competition for most of our products is primarily on the basis of price, product quality and our ability to meet delivery requirements. Competition may also be affected by inventory availability, customer service, processing capabilities, technology adoption and the ability to respond quickly to changing customer requirements. Our business has been subject to increasing consolidation of suppliers. Depending on a variety of factors, including raw material, energy, labor and capital costs, freight availability and government subsidies of foreign steel producers or competitors, our business may be materially adversely affected by competitive forces. Competition may also increase if suppliers to or customers in the steel industry begin to more directly compete with our business through new facilities, acquisitions or otherwise. As noted above, we may have conflicts with our customers or suppliers who, in some cases, supply the same products and services as we do. Competitors may adopt new technologies, automation or production methods that could improve their cost structure or product offerings relative to ours. Increased competition could cause us to lose market share, increase expenditures, lower our margins or offer additional services at a higher cost to us, which could adversely impact our financial results.

Material or Component Substitution

If steel prices increase compared to certain substitute materials, the demand for our products could be negatively impacted, which could have an adverse effect on our financial results. In certain applications, steel competes with other materials, such as aluminum (particularly in the automotive industry), cement and wood (particularly in the construction industry), and composites. Prices of all of these materials fluctuate widely, and differences between the prices of these materials and the price of steel may adversely affect demand for our products and/or encourage material substitution, which could adversely affect the prices of and demand for our steel products. The higher cost of steel relative to certain other materials may make material substitution more attractive for certain uses and result in our customers reducing their purchases from us, which would negatively impact our results of operations.

If government fuel efficiency and/or emissions standards for automobiles result in the substitution of other materials for steel, or the substitution of electric motors for internal combustion engines, demand for our products could be negatively impacted, which could have an adverse effect on our financial results. Due to government requirements that manufacturers increase the fuel efficiency of automobiles, the automotive industry is exploring alternative materials to steel in order to decrease weight and increase mileage. In addition, in an effort to reduce emissions, the automotive industry is also shifting toward products that rely on electric motors instead of internal combustion engines. Although our product offerings include certain lightweighting solutions and electric motor components, the substitution of lighter weight material for steel and/or electric motors for internal combustion engines in automobiles could adversely affect prices of and demand for certain of our steel products. Conversely, if government fuel efficiency and/or emission standards for automobiles are reduced or eliminated, demand for our lightweighting solutions and electric motor components could be reduced over time, which would negatively impact our results of operations.

Freight and Energy

Increasing freight and energy costs could increase our operating costs or the costs of our suppliers, who may seek to pass those increased costs on to us, all of which could have an adverse effect on our financial results. The availability and cost of freight and energy, such as electricity, natural gas and diesel fuel, are important in the manufacture and transport of our supplies and products. Our operations consume substantial amounts of energy, and our operating costs generally increase when energy costs rise. Factors that may affect our energy costs include significant increases in fuel, oil or natural gas prices, unavailability of electrical power or other energy sources due to droughts, hurricanes or other natural causes or due to shortages resulting from insufficient supplies to serve customers, or interruptions in energy supplies due to equipment failure, international conflict or other causes. Increased electricity demand, including demand related to electrification of the economy, industrial growth or significant new power users such as data centers, could contribute to higher utility rates, increased infrastructure costs or constraints on available power. During periods of increasing energy and freight costs, we may be unable to fully recover our operating cost increases or the increases in the costs of our supplies through price increases to our customers without reducing demand for our products. Our financial results could be adversely affected if we are unable to pass all of the cost increases on to our customers or if we are unable to obtain the necessary freight and/or energy. Also, increasing energy costs could put a strain on the transportation of our materials and products if the increased costs force certain transporters to discontinue their operations.

We depend on third parties for freight services and increases in the cost or the lack of availability of freight services can adversely affect our operations. We rely primarily on third parties for transportation of our products as well as delivery of our raw materials, primarily by truck. If, due to a lack of freight services, raw materials or supplies are not delivered to us in a timely manner, we may be unable to manufacture and deliver our products to meet customer demand. Likewise, if due to a lack of freight services, we cannot deliver our products in a timely manner, it could harm our reputation, negatively affect our customer relationships and have a material adverse effect on our results of operations. In addition, any increase in the cost of the transportation of raw materials or our products, as a result of increases in fuel or labor costs, higher demand for logistics services, international conflict or otherwise, may adversely affect our results of operations as we may not be able to pass such cost increases on to our customers. Disruptions in transportation networks, including capacity constraints, labor shortages or regulatory changes, could further impact the availability and cost of freight services.

Public Health Emergencies

Public health emergencies could have a material adverse effect on our business financial position, results of operations and cash flows. Our operations expose us to risks associated with epidemics and other public health emergencies. Impacts of future public health emergencies may include, without limitation, potential significant volatility or continued decreases in the demand for our products, changes in customer and consumer behavior and preferences, disruptions in or additional closures of our manufacturing operations or those of our customers and suppliers, disruptions within our supply chain, limitations on our employees’ ability to work and travel, potential financial difficulties of customers and suppliers, slower payment of accounts receivable and potential increases in uncollectible accounts receivable, significant changes in economic or political conditions, and related volatility in the financial and commodity markets, including volatility in raw material and other input costs. Impacts of future public health emergencies may include, without limitation, potential significant volatility or continued decreases in the demand for our products, 10 Table of Contents changes in customer and consumer behavior and preferences, disruptions in or additional closures of our manufacturing operations or those of our customers and suppliers, disruptions within our supply chain, limitations on our employees’ ability to work and travel, potential financial difficulties of customers and suppliers, slower payment of accounts receivable and potential increases in uncollectible accounts receivable, significant changes in economic or political conditions, and related volatility in the financial and commodity markets, including volatility in raw material and other input costs. The extent to which public health emergencies impact our business will depend on future developments, which cannot be predicted and are highly uncertain. Despite our efforts to manage the impacts, the degree to which public health emergencies and related actions ultimately impact our business, financial position, results of operations and cash flows will depend on factors beyond our control including the duration, extent and severity of any future public health emergency, the actions taken to contain the future public health emergencies and mitigate their public health effects, the impact on the U.S. and global economies and demand for our products, and to what extent normal economic and operating conditions resume. Future disruption to the global economy, as well as to the end markets our business serves, could result in material adverse effects on our business, financial position, results of operations and cash flows.

The ongoing conflict between Russia and Ukraine may adversely affect our business and results of operations.

Since early 2022, Russia and Ukraine have been engaged in active armed conflict. The length, impact and outcome of the ongoing conflict and its potential impact on our business is highly volatile and difficult to predict. It has caused, and could continue to cause, significant market and other disruptions, including significant volatility in commodity prices and supply of energy resources, instability in financial markets, supply chain interruptions, political and social instability, trade disputes or trade barriers, changes in consumer or purchaser preferences, and increases in cyberattacks and espionage.

We do not conduct business, either directly or indirectly, in areas materially impacted by the conflict and, as such, we believe our exposure is primarily indirect, including impacts on macroeconomic conditions, commodity and energy prices, and global supply chains. However, the scope, duration and severity of the conflict remain uncertain, and its indirect effects on global markets, supply chains and input costs may continue to adversely affect our business.

The conflict between the United States, Israel and Iran and related geopolitical instability may adversely affect our business.

In February 2026, the United States and Israel launched coordinated military strikes against Iran, which retaliated with missile attacks across the region. Although we do not have material operations in the Middle East, the ongoing conflict and any further escalation, including additional military actions, retaliatory measures, sanctions, disruptions to trade or transportation routes, cyberattacks, or other governmental or market responses, has and could continue to lead to significant disruption of global energy supplies and increases in global energy prices, heighten inflationary pressures on our input costs and supply chain, adversely affect global supply chains, energy markets, commodity prices, currency exchange rates, interest rates, financial markets and overall macroeconomic conditions, increase the cost or reduce the availability of debt financing, and adversely impact customer spending patterns in markets in which we operate. While the impacts of conflict between the United States, Israel, and Iran may have an adverse effect on our business, financial condition and results of operations, we are unable to predict the extent or nature of these impacts at this time. If the Former Parent in the future decides to engage in the type of business we conduct, it may have a competitive advantage over us, which may cause our business, financial condition and results of operations to be materially adversely affected.

Information Systems and Cybersecurity

We are subject to information system security risks and systems integration issues that could disrupt our operations. We are dependent upon information technology and networks in connection with a variety of business activities, including the distribution of information internally and to our customers and suppliers. These systems may include information technology and operational technology systems used to support business processes, production activities, inventory management, financial reporting and communications. This information technology is subject to potential damage or interruption from a variety of sources, including, without limitation, systems failures, computer viruses, security breaches, technology obsolescence, and natural disasters. We rely on third-party service providers and cloud-based systems, which may increase our exposure to cybersecurity and operational risks outside of our direct control. We could also be adversely affected by system or network disruptions if new or upgraded business management systems are defective, not installed properly or not properly integrated into operations.

Security breaches of our information systems could result in unauthorized misappropriation, disclosure or destruction of confidential or proprietary information, production downtime and/or the loss of the functionality of our systems. These risks may be increased as more employees continue to work remotely. Various measures have been implemented to manage our risks related to information system and network disruptions and to prevent attempts to gain unauthorized access to our information systems. While we undertake mitigating activities to counter these risks, there can be no assurance that such activities will be sufficient to prevent cyberattacks or security breaches or mitigate all potential risks to our systems, networks and data. A system failure could negatively impact our operations and financial results and cyberattacks could threaten the integrity of our trade secrets and sensitive intellectual property.

As cybersecurity threats continue to increase in frequency, sophistication, and scale, especially through the use of AI, we may be required to incur significant costs and invest additional resources to protect against and, if required, remediate the damage caused by such disruptions or system failures in the future.As cybersecurity threats continue to evolve and become more sophisticated, including through the use of artificial intelligence, we may be required to incur significant costs and invest additional resources to protect against and, if required, remediate the damage caused by such disruptions or system failures in the future. Threat actors may use AI-enhanced techniques, and may also attempt to exploit vulnerabilities introduced through third-party software, cloud-based services, vendor software updates or other software supply chain compromises. The potential consequences of a material cybersecurity attack include reputational damage, investigations and/or adverse proceedings with regulators and enforcement agencies, litigation with third parties, disruption to our systems (including production capabilities), unauthorized release of confidential, personally identifiable or otherwise protected information, corruption of data, and increased cybersecurity protection and remediation costs, which in turn could adversely affect our competitiveness, results of operations and financial condition. Insurance coverage for cyberattacks may become unavailable, may not cover the types of losses we may incur, and may be inadequate in amount to cover liabilities resulting from a cyberattack. Refer to Item 1C: “Cybersecurity” for further information on our Cybersecurity processes, policies, and programs.

Artificial Intelligence Technologies and Machine Learning

We have begun using commercially available AI technologies to enhance productivity and support internal human in the loop decision-making. We are not engaged in high-risk or autonomous AI systems that materially influence customer-facing decisions or critical infrastructure. As we continue to evaluate and expand these tools across our workforce, their use presents a number of risks and uncertainties.

Some AI tools, particularly generative models, may generate outputs that are not easily auditable or explainable, which could impact the reliability of internal analyses or recommendations if not subject to appropriate human oversight. Reliance on flawed outputs could adversely impact business decisions, internal analyses, and operational workflows. Additionally, the use of AI to process sensitive, proprietary, or personal data introduces cybersecurity and data privacy risks, including the potential for data leakage, unauthorized access, or unintended disclosure, particularly when integrated with third-party platforms or cloud-based services.

The legal and regulatory landscape for AI is evolving rapidly and may impose future compliance obligations or restrictions. Additionally, reliance on third-party AI providers could expose us to service disruptions, quality concerns, or liability for unintended consequences. If not effectively managed, these risks could adversely affect our operations, reputation, or financial results.

We have developed AI enterprise governance structure, along with a Technology Governance Committee and a Data Asset and Information Management program, to help ensure responsible, secure, and ethical use of AI and data assets across the business.

Business Disruptions

Disruptions to our business or the business of our customers or suppliers could adversely impact our operations and financial results. Business disruptions, including delayed or insufficient materials resulting from shortages of supply or transportation, severe weather events (such as hurricanes, tsunamis, earthquakes, tornados, floods, droughts and blizzards), casualty events (such as explosions, fires or material equipment breakdown), acts of terrorism, international conflicts, labor disruptions, equipment failures, the idling of facilities due to reduced demand (resulting from a downturn in economic activity or otherwise), public health emergencies or other health crises, or other events, could cause interruptions to our business as well as the operations of our customers and suppliers. Additionally, unexpected extended equipment downtime on certain of our plants’ specialized equipment, including galvanizing lines and presses, could cause interruptions to our ability to meet customer requirements. Long lead times for replacement parts, specialized equipment or critical spares could extend the duration or cost of any such disruption. While we maintain insurance coverage that may offset some losses relating to certain types of these events, losses from business disruptions could have an adverse effect on our operations and financial results, and we could be adversely impacted to the extent any such losses are not covered by insurance or cause some other adverse impact to us.

Foreign Operations

Economic, political and other risks associated with foreign operations could adversely affect our financial results. Although the substantial majority of our business activity takes place in the U.S., we derive a portion of our revenues and earnings from operations in foreign countries, which is expected to increase with our investment in foreign locations. As a result, we are subject to risks associated with doing business internationally. The risks of doing business in foreign countries include, among other factors: the potential for adverse changes in the local political climate, in diplomatic relations between foreign countries and the U.S. or in government policies, laws or regulations; international conflicts; terrorist activity that may cause social disruption; logistical and communications challenges; costs of complying with a variety of laws and regulations; difficulty in staffing and managing geographically diverse operations; deterioration of foreign economic conditions; inflation and fluctuations in interest rates; foreign currency exchange rate fluctuations; foreign exchange restrictions; differing local business practices and cultural considerations; restrictions on imports and exports or sources of supply, including energy and raw materials; changes in duties, quotas, tariffs, taxes or other protectionist measures; and potential issues related to matters covered by the Foreign Corrupt Practices Act, regulations related to import/export controls, the Office of Foreign Assets Control sanctions program, anti-boycott provisions or similar laws. We believe that our business activities outside of the U.S. involve a higher degree of risk than our domestic activities, and any one or more of these factors could adversely affect our operating results and financial condition. Evolving regulatory requirements, including environmental and data privacy regulations in foreign jurisdictions, may increase compliance costs and operational complexity. Global and regional economic conditions and the volatility of worldwide capital and credit markets have significantly impacted and may continue to significantly impact our foreign customers and markets. In addition, global and regional economic conditions and the volatility of worldwide capital and credit markets have significantly impacted and may continue to significantly impact our foreign customers and markets. These factors may result in decreased demand in our foreign operations. To the extent we hold equity investments in foreign entities or markets, these risks may also impact the value and performance of such investments. Refer to the “Economic or Industry Downturns and Weakness” risk factors herein for additional information concerning the impact of the global economic conditions and the volatility of capital and credit markets on our business.

Joint Ventures and Investments

A change in the relationship between the members of any of our joint ventures may have an adverse effect on that joint venture and our financial results. We have been successful in the development and operation of various joint ventures. We believe an important element in the success of any joint venture is a solid relationship between the members of that joint venture. If there is a change in ownership, a change of control, a change in management or management philosophy, a change in business strategy or another event with respect to a member of a joint venture that adversely impacts the relationship between the joint venture members, it could adversely impact that joint venture. If there is a change in ownership, a change of control, a change in management or management philosophy, a change in business strategy or another event with respect to a 12 Table of Contents member of a joint venture that adversely impacts the relationship between the joint venture members, it could adversely impact that joint venture. The other members in our joint ventures may also, as a result of financial or other reasons, be unable or unwilling to support actions that we believe are in the best interests of the respective joint ventures. In addition, joint ventures necessarily involve special risks. Whether or not we hold a majority interest or maintain operational control in a joint venture, the other members in our joint ventures may have economic or business interests or goals that are inconsistent with our interests or goals. For example, because they are joint ventures, we do not have full control of every aspect of the joint venture’s business and/or certain significant decisions concerning the joint venture, which may require certain approvals from the other members in our joint ventures, and the other members in our joint ventures may be unwilling or unable to support actions that we believe to be in our best interests, may take action contrary to our policies or objectives with respect to our investments, or may otherwise be unable or unwilling to support actions that we believe are in the best interests of the respective joint venture, each of which could have an adverse effect on that joint venture and our financial results. Where we do not hold a majority interest in a joint venture (i.e., the unconsolidated joint venture Serviacero Worthington in which we own a 50% noncontrolling interest), our ability to control the direction and operations of that joint venture is limited and our investment in that joint venture is significantly dependent on the other member of the joint venture. The failure of the other member of the unconsolidated joint venture to properly manage and operate the joint venture could have an adverse effect on that joint venture and our financial results.

Acquisitions and Equity Investments

We may be unable to successfully consummate, manage or integrate our acquisitions or other equity investments or our acquisitions and investments may not meet our expectations. We may from time to time seek attractive opportunities to acquire businesses, enter into joint ventures and make other investments that are complementary to our existing strengths. There are no assurances, however, that any acquisition or investment opportunities will arise or, if they do, that they will be consummated, or that any needed additional financing for such opportunities will be available on satisfactory terms when required. In addition, acquisitions and investments involve risks that the businesses acquired or in which we invest will not perform in accordance with our expectations, that business judgments concerning the value, strengths and weaknesses of businesses will prove incorrect, that we may assume unknown liabilities from the seller, that the businesses may not be integrated successfully and that the acquisitions and investments may strain our management resources or divert management’s attention from other business concerns. Integration efforts may also be more complex and costly than anticipated, particularly for cross-border transactions or those involving differing regulatory frameworks or business practices. Costs and investments in excess of our expectations may be required to implement necessary compliance processes and related systems, including IT systems, accounting systems and internal controls over financial reporting.

International acquisitions and investments may present unique challenges and increase our exposure to the risks associated with foreign operations and countries. International acquisitions and investments may present unique challenges and increase our exposure to the risks associated with foreign operations and countries. Also, failure to successfully integrate any of our acquisitions may cause significant operating inefficiencies and could adversely affect our operations and financial condition. Even if the operations of an acquisition are integrated successfully, we may fail to realize the anticipated benefits of the acquisition, including the synergies, cost savings or growth opportunities that we expect. These benefits may not be achieved within the anticipated timeframe, or at all. Failing to realize the benefits anticipated from an acquisition or investment could have a material adverse effect on our financial condition and results of operations. We may also fail to identify all risks, liabilities or control deficiencies during due diligence, including those related to environmental matters, tax positions, regulatory compliance, cybersecurity, accounting practices or internal controls.

Our investments in equity securities, including those in publicly and privately held companies in which we do not have a controlling interest or significant influence, may be subject to market price volatility, limited liquidity, and valuation uncertainty. Changes in the fair value of equity securities with readily determinable fair values, as well as impairments or observable price adjustments for equity securities without readily determinable fair values, are recognized in net earnings and may introduce increased volatility in our results of operations and financial condition.

Capital Expenditures and Capital Resources

Our business requires capital investment and maintenance expenditures, and our capital resources may not be adequate to provide for all of our cash requirements. Many of our operations are capital intensive. For the fiscal year ended May 31, 2026, our total capital expenditures were approximately $121.2 million. Additionally, as of May 31, 2026, we were obligated under lease agreements to make aggregate operating lease payments of $106.8 million and finance lease payments of $8.7 million. Additionally, as of May 31, 2025, we were obligated under lease agreements to make aggregate operating lease payments of $94.1 million. Our business also requires expenditures for maintenance of our facilities. Given the potential for challenges, uncertainty and volatility in the domestic and global economies and financial markets, there can be no assurance that our capital resources will be adequate to provide for all of our cash requirements. Our capital allocation decisions, including investments in capacity expansion, acquisitions and equity securities, may not achieve expected returns and could adversely affect our financial condition.

Our significant strategic capital investments may not achieve their intended return on investment, which could adversely affect our financial condition and results of operations. We have committed and deployed significant capital to strategic growth initiatives, including large-scale plant expansions in Mexico and Canada. These projects are intended to increase our processing capacity and support anticipated growth in markets such as electrical steel. The successful performance of these investments depends on achieving the anticipated customer demand to support profitable utilization of these new facilities. There can be no assurance that market demand will materialize at levels sufficient to support the expected volumes, margins, or timing necessary to achieve our internal forecasts. The cost or time required to implement strategic or sustaining capital projects may also prove to be greater than originally anticipated due to supply chain issues, labor availability, permitting delays, funding constraints, changes in project scope, equipment lead times or other factors beyond our control. If we are unable to secure sufficient customer orders or if demand for our products grows at a slower rate than expected, the newly expanded capacity may be underutilized. This could result in a lower-than-expected return on investment, adversely impacting our profitability and potentially reducing the effectiveness of our capital allocation strategy.

Capital Structure

Increased leverage and borrowing rates could adversely impact our business and results of operations. On June 1, 2026, we incurred indebtedness in the form of (1) 2033 Notes, which mature June 1, 2033, and (2) Term Loans under the Term Loan Facility. We may also incur additional indebtedness in the future. The terms of our debt restrict but do not prohibit us from doing so, and the indebtedness incurred in compliance with these restrictions could be substantial. The terms of the Revolving Credit Facility restrict but do not prohibit us from doing so, and the indebtedness incurred in compliance with these restrictions could be substantial. If new indebtedness is added to our current debt levels, the related risks that we now face could intensify.

Our ability to make payments on our indebtedness depends on our ability to generate cash in the future. Our ability to make payments on our indebtedness depends on our ability to generate cash in the future. Accordingly, we will have to generate significant cash flows from operations to meet our debt service requirements. Accordingly, we will have to generate significant cash flows from operations to meet our debt service requirements. If we do not generate sufficient cash flow to meet our debt service and working capital requirements, we may be required to seek additional capital, reduce capital expenditures, restructure or refinance all or a portion of our existing indebtedness, or sell assets. Moreover, insufficient cash flow may make it more difficult for us to obtain financing on terms that are acceptable to us, or at all.

While we expect to utilize our Revolving Credit Facility for certain growth initiatives, larger-scale opportunities may require access to alternative funding sources, which could be difficult. We expect to finance our growth initiatives through borrowings under our 2031 Revolving Credit Facility, which was entered into on June 25, 2026, and matures on June 25, 2031, and that replaced the Revolving Credit Facility, which was paid off and terminated June 25, 2026. However, our 2031 Revolving Credit Facility may not be sufficient or available to finance our growth initiatives, and we may have to find additional sources of financing in addition to the Notes and Term Loans and existing indebtedness. It may be difficult for us in the future to obtain the necessary funds and liquidity on terms acceptable to us, or at all, to run and expand our business.

Because the Revolving Credit Facility, Term Loans, certain Sitem Group Loans, and BDC Loan bear interest at rates that fluctuate with changes in certain prevailing short-term interest rates, we are vulnerable to interest rate increases. An increase in interest rates would increase our interest expense on the Revolving Credit Facility, Term Loans, certain Sitem Group Loans, and BDC Loan. If interest rates rise in the future, we could be unable to service our debt, which could have a material adverse effect on our business, financial condition, results of operations, or cash flows.

Difficult Financial Markets

If we are required to raise capital in the future, we could face higher borrowing costs, less available capital, more stringent terms and tighter covenants or, in extreme conditions, an inability to raise capital. Although we currently have cash reserves, as well as adequate borrowing availability for our existing business under our 2031 Revolving Credit Facility and should be able to access other capital if needed, should those facilities become unavailable due to covenant or other defaults, or should financial markets tighten so that we otherwise cannot raise capital outside our existing facilities, or the terms under which we do so change, we may be negatively impacted. Although we currently have cash reserves, as well as adequate borrowing availability for our existing business under our existing Revolving Credit Facility and should be able to access other capital if needed, should those facilities become unavailable due to covenant or other defaults, or should financial markets tighten so that we otherwise cannot raise capital outside our existing facilities, or the terms under which we do so change, we may be negatively impacted. Any adverse change in our access to capital or the terms of our borrowings, including increased costs, could have a negative impact on our financial condition.

Guidance Regarding Future Performance

We may release guidance regarding our anticipated future performance and such guidance may prove to be inaccurate. Such guidance, which consists of forward-looking statements, is qualified by and subject to various assumptions and estimates, including the information included in our annual reports on Form 10-K and our quarterly reports on Form 10-Q. Such assumptions and estimates are inherently subject to a variety of uncertainties and contingencies, many of which are beyond our control and are based upon expectations with respect to future decisions, some of which will change. Guidance is necessarily speculative in nature, and it can be expected that some or all of the assumptions of the guidance furnished by us will not materialize or will vary significantly from actual results. Accordingly, our guidance is only an estimate of what management believes is realizable as of the date of release. Actual results will vary from the guidance. Any failure to successfully implement our operating strategy or the occurrence of any of the risks described in our annual reports on Form 10-K or our quarterly reports on Form 10-Q could cause actual operating results to differ from the guidance, and such differences may be adverse and material. Accordingly, investors are urged not to place undue reliance on guidance.

Legal Proceedings

We may be subject to legal proceedings or investigations, the resolution of which could negatively affect our results of operations and liquidity. Our results of operations or liquidity could be affected by an adverse ruling in any legal proceedings or investigations which may be pending against us or filed against us in the future. We are also subject to a variety of legal and compliance risks, including, without limitation, potential claims relating to product liability, privacy and information security, health and safety, labor and employment, environmental matters, taxes and compliance with U.S. and foreign export laws, anti-bribery laws, competition laws and sales and trade practices. While we believe that we have adopted appropriate risk management and compliance programs to address and reduce these risks, the global and diverse nature of our operations means that these risks will continue to exist and additional legal proceedings and contingencies may arise from time to time. The insurance we maintain may not be adequate or available to protect us in the event of a claim or its coverage may be limited, canceled or otherwise terminated, or the amount of our insurance may be less than the related impact on our enterprise value after a loss. As appropriate, we establish reserves based on our assessment of contingencies, including contingencies for claims asserted against us in connection with certain legal proceedings. Adverse developments in legal proceedings may affect our assessment and estimates of the loss contingency recorded as a reserve and require us to make payments in excess of our reserves, which could negatively affect our operations, financial results and cash flows. Adverse 14 Table of Contents developments in legal proceedings may affect our assessment and estimates of the loss contingency recorded as a reserve and require us to make payments in excess of our reserves, which could negatively affect our operations, financial results and cash flows. An adverse ruling or settlement or an unfavorable change in laws, rules or regulations could have a material adverse effect on our financial condition and results of operations.

Claims and Insurance

Adverse claims experience, to the extent not covered by insurance, may have an adverse effect on our financial results. We self-insure most of our risks for product recall and pollution liability. We also self-insure a significant portion of our potential liability for workers’ compensation, product liability, general liability, property liability, cyber liability, automobile liability and employee medical claims, and in order to reduce risk for these liabilities, we purchase insurance from highly rated, licensed insurance carriers that cover most claims in excess of the applicable deductible or retained amounts. We also maintain reserves for the estimated cost to resolve certain open claims that have been made against us, as well as an estimate of the cost of claims that have been incurred but not reported. The occurrence of significant claims, our failure to adequately reserve for such claims, a significant cost increase to maintain our insurance or the failure of our insurance providers to perform could have an adverse impact on our financial condition and results of operations.

Accounting and Tax-Related Estimates

We are required to make accounting and tax-related estimates, assumptions and judgments in preparing our combined financial statements, and actual results may differ materially from the estimates, assumptions and judgments that we use. In preparing our consolidated financial statements in accordance with accounting principles generally accepted in the U.S. (“GAAP”), we are required to make certain estimates and assumptions that affect the accounting for and recognition of assets, liabilities, revenues and expenses. These estimates and assumptions must be made because certain information that is used in the preparation of our combined financial statements is dependent on future events or cannot be calculated with a high degree of precision from data available to us. In some cases, these estimates and assumptions are particularly difficult to determine and we must exercise significant judgment. Some of the estimates, assumptions and judgments having the greatest amount of uncertainty, subjectivity and complexity are related to our accounting for bad debts, returns and allowances, inventory, self-insurance reserves, derivatives, stock-based compensation, deferred tax assets and liabilities and asset impairments. Our actual results may differ materially from the estimates, assumptions and judgments that we use, which could have a material adverse effect on our financial condition and results of operations.

Principal Shareholder

The principal shareholder of Worthington Steel may have the ability to exert significant influence in matters requiring a shareholder vote and could delay, deter or prevent a change in control of Worthington Steel. Pursuant to the charter documents of Worthington

Steel, certain matters such as those in which a person would attempt to acquire or take control of Worthington Steel, must be approved by the vote of the holders of common shares representing at least 75% of Worthington Steel’s outstanding voting power. Approximately 34% of the outstanding common shares are beneficially owned, directly or indirectly, by John P. McConnell. As a result of his beneficial ownership of these common shares, Mr. McConnell may have the ability to exert significant influence in these matters and other proposals upon which shareholders may vote.

Employees

The loss of, or inability to attract and retain, qualified personnel could adversely affect our business. Our ability to successfully operate, grow our business and implement our business strategies is largely dependent on the efforts, abilities and services of our employees. The loss of employees or our inability to attract, train and retain additional personnel could reduce the competitiveness of our business or otherwise impair our operations or prospects. Our future success will also depend, in part, on our ability to attract and retain qualified personnel, including engineers and other skilled technicians, who have experience in the application of our products and are knowledgeable about our business, markets and products.

The loss of senior management or other key employees, or failure to implement effective succession planning strategies, may have a material adverse impact on our business. We cannot assure that we will be able to retain our existing senior management personnel or other key employees or attract additional qualified personnel when needed. The loss of any member of our management team could adversely impact our business and operations. We have not entered into any formal employment agreements or other stand-alone change in control provisions with our executive officers. We have not entered into any formal employment contracts with or other stand-alone change in control provisions relative to our executive officers. However, we do have certain change in control provisions in our various compensation plans. We may modify our management structure from time to time or reduce our overall workforce, which may create marketing, operational and other business risks. If we lose members of our management team or other key employees and fail to implement effective succession plans, our business and results of operations may be negatively impacted.

We may not realize the expected benefits of headcount reductions, facility closures or other cost reduction efforts. We may from time to time take actions intended to reduce costs, improve efficiency or better align our operations with customer demand, including headcount reductions, facility closures, consolidations or other restructuring or cost reduction initiatives. These actions may not result in the anticipated expense reductions, operating efficiencies or other benefits within the expected timeframe, or at all, and may result in additional costs. In addition, such actions could adversely affect employee morale, our ability to attract and retain qualified personnel, customer service levels or our ability to respond to future demand, any of which could adversely affect our business, financial condition and results of operations.

Environmental, Health and Safety

We may incur additional costs related to environmental and health and safety matters. Our operations and facilities are subject to a variety of federal, state, local and foreign laws and regulations relating to the protection of the environment and human health and safety. Compliance with these laws and regulations and any changes therein may sometimes involve substantial operating costs and capital expenditures, and any failure to maintain or achieve compliance with these laws and regulations or with the permits required for our operations could result in increased costs and capital expenditures and potentially fines and civil or criminal sanctions, third-party claims for property damage or personal injury, cleanup costs or temporary or permanent discontinuance of operations.

Our safety performance may adversely affect our business, results of operations and reputation. Over time, we and predecessor operators of our facilities have generated, used, handled and disposed of hazardous and other regulated wastes. Environmental liabilities, including cleanup obligations, could exist at our facilities or at off-site locations where materials from our operations were disposed of or at facilities we have divested, which could result in future expenditures that cannot be currently quantified and which could reduce our profits and cash flow. We may be held strictly liable for any contamination of these sites, and the amount of any such liability could be material. Under the joint and several liability principle of certain environmental laws, we may be held liable for all remediation costs at a particular site, even with respect to contamination for which we are not responsible. In addition, changes in environmental and human health and safety laws, rules, regulations or enforcement policies could have a material adverse effect on our business, financial condition or results of operations.

Seasonality

Our operations have historically been subject to seasonal fluctuations that may impact our cash flows for a particular period. Our sales are generally strongest in the fourth quarter of the fiscal year when our business is normally operating at seasonal peaks, and our sales are generally weakest in the third quarter of the fiscal year, primarily due to reduced activity in the construction industry as a result of the colder, more inclement weather throughout much of the U.S., as well as customer plant shutdowns in the automotive industry due to holidays. Our quarterly results may also be affected by the timing of large customer orders. Consequently, our cash flow from operations may fluctuate significantly from quarter to quarter. If, as a result of any such fluctuation, our quarterly cash flows were significantly reduced, we may be unable to service our indebtedness or maintain compliance with certain covenants under the documents governing our indebtedness. A default under any of the documents governing our indebtedness could prevent us from borrowing additional funds, limit our ability to pay interest or principal and allow our lenders to declare the amounts outstanding to be immediately due and payable and to exercise certain other remedies.

Transformation

We may not realize the expected benefits of our strategic, operational, technology or other business initiatives. We may from time to time undertake initiatives intended to improve our performance, efficiency, competitiveness, systems, processes, cost structure, inventory management, sourcing, supply chain or customer service. These initiatives may require significant management attention, capital expenditures, technology investments or other resources, and may not achieve the anticipated benefits within the expected timeframe, or at all. Implementation of these initiatives could result in unexpected costs, operational disruption, changes to our business processes or distraction of management and employees, any of which could adversely affect our business, financial condition and results of operations.

Risks Related to the Kloeckner Acquisition

Restrictions on our interactions with Kloeckner may delay or limit the implementation of our integration strategy and could adversely impact our results of operations. On June 3, 2026, we completed the Kloeckner Acquisition and held approximately 60.9% of Kloeckner’s outstanding share capital. Through a subsequent transaction on June 15, 2026, we acquired an additional one million Kloeckner shares and now hold approximately 61.9% of Kloeckner’s outstanding share capital. As a result, there remain minority Kloeckner shareholders that did not tender their Kloeckner shares in connection with the original takeover offer. On July 15, 2026, we launched a public delisting tender offer for all outstanding Kloeckner shares not already held by us at a price of €11.00 per share. The delisting tender offer is not subject to any closing conditions and does not include a minimum acceptance threshold; however, there can be no assurance as to how many Kloeckner shares, if any, will be tendered.

Under German law, we are subject to certain restrictions in our interactions with Kloeckner while minority shareholders continue to hold more than 10% of outstanding Kloeckner shares until and unless a DPLTA is established. On March 27, 2026, we informed Kloeckner about our firm intention to enter into a DPLTA, and Kloeckner published an ad hoc announcement to this effect on the same day. While we are confident that we will secure the required majority at the general meeting of Kloeckner shareholders to approve the DPLTA, unless and until a DPLTA is executed and becomes effective, we may not have control over the day-to-day operations of Kloeckner. However, we do anticipate having a controlling financial interest under GAAP accounting standards. These restrictions could limit the implementation of our strategy and may adversely impact our results of operations. These conditions also increase the risk that our customers may delay or default on their payment obligations to us. There can be no assurance that a DPLTA will become effective.

If a DPLTA is executed and becomes effective, we will be subject to ongoing financial obligations to Kloeckner and its minority shareholders that could adversely affect our business, financial condition, results of operations or cash flows. If a DPLTA is executed and becomes effective, under the applicable provisions of the German Stock Corporation Act, we would be obligated to compensate any annual net loss of Kloeckner. Furthermore, each remaining minority Kloeckner shareholder would have the option to either:

Kloeckner shareholders choosing the first option may later elect the second option. Our obligation to pay annual recurring compensation could result in a continuous payment obligation that may be higher than the minimum dividends that would otherwise be distributed. Our obligation to, upon shareholder demand, provide adequate exit compensation in exchange for Kloeckner shares could require us to use significant cash or other financing resources and may be subject to appraisal proceedings that could result in higher payments than anticipated. There can be no assurance that, if a DPLTA becomes effective, the related obligations will not adversely affect our business, financial condition, results of operations or cash flows.

Failure to successfully integrate our business and Kloeckner’s business in the expected timeframe may adversely affect our future results. In January 2026, we entered into a business combination agreement (“BCA”) with Kloeckner and launched a voluntary public cash takeover offer with all outstanding Kloeckner shares at €11.00 per share. We entered into the BCA with the expectation that the Kloeckner Acquisition will result in various benefits, including certain cost savings, operational efficiencies or synergies, and an accretive effect on our earnings. To realize these anticipated benefits, our business and Kloeckner’s business must be successfully integrated. The integration may be complex and time-consuming and may require substantial resources and effort. Our management may face significant challenges in consolidating our operations and Kloeckner’s operations, integrating the two companies’ technologies, procedures, and policies, as well as addressing the different corporate cultures of the two companies. If the companies are not successfully integrated, the anticipated benefits of the Kloeckner Acquisition, including estimated cost, operations and commercial synergies and the timeline to realize such synergies, may not be realized fully or at all, or may take longer to realize than expected.

Additionally, our ability to realize anticipated benefits of the Kloeckner Acquisition could be affected by a number of other factors, including: the need for greater than expected cash or other financial resources or management time in order to integrate Kloeckner’s business; increases in other expenses related to the Kloeckner Acquisition, including restructuring costs; the timing and impact of purchase accounting adjustments; accounting for IFRS to GAAP adjustments; difficulties in employee or management integration; adverse tax impacts; the impact of appraisal proceedings in connection with the DPLTA; adverse tax impacts related to implementation of the DPLTA, or other unanticipated factors; and unanticipated liabilities associated with the Kloeckner Acquisition. Any potential cost-saving opportunities may take several years following the Kloeckner Acquisition to implement, and any results of these actions may not be realized for several years thereafter, if at all. Until and unless the DPLTA becomes effective, we may not be able to realize any or all of the expected benefits of the Kloeckner Acquisition.

We must continue to retain, recruit and motivate executives and other key employees, and failure to do so could negatively affect us. The success of the Kloeckner Acquisition and our post-closing integration efforts depends, in part, on our ability to retain, recruit and motivate executives and other key employees for the benefits of the transaction to be fully realized. Our and Kloeckner’s employees may experience uncertainty about their future roles until, or even after, strategies regarding the Kloeckner Acquisition are announced and executed. Some of those employees may decide not to remain with us or Kloeckner as a result of the Kloeckner Acquisition. If key employees terminate their employment, or if an insufficient number of employees are retained to maintain effective operations, our business activities may be adversely affected, and management’s attention may be diverted from successfully integrating Kloeckner to hiring suitable replacements. The potential distractions related to the Kloeckner Acquisition may adversely affect our ability to keep executives and other key employees focused on business strategies and goals, to address other important personnel matters and to retain them at all. A failure by us or Kloeckner to attract, retain and motivate executives and other key employees could have a negative impact on our business and our financial results and operations.

The Kloeckner Acquisition may limit our financial flexibility and increase our interest expense. We funded the consideration for the Kloeckner Acquisition and related transaction costs with both U.S. Dollars and Euros with a combination of cash on hand and new debt financing, including the net proceeds from our previously announced notes offering and borrowing under our term loan. The new debt financing contains covenants limiting or restricting our ability to take certain actions, such as incurring additional debt, or under certain situations, making capital expenditures or increasing dividends beyond current levels, which could limit our financial flexibility. Elevated levels of debt driven by the new debt financing may cause us to miss out on other opportunities to grow our business such as other acquisitions or capital projects. See “Risks Related to Our Business—Capital Structure” for more information on our debt financing.

Litigation or appraisal proceedings relating to the Kloeckner Acquisition and/or any DPLTA may result in management distraction or financial exposure. Lawsuits may be filed against us, our board of directors, Kloeckner, or other parties to the BCA, in connection with the Kloeckner Acquisition. In addition, if a DPLTA becomes effective, minority shareholders may initiate appraisal proceedings concerning the adequacy of the compensation or exit consideration offered to them under the DPLTA. While such appraisal proceedings would not affect the effectiveness of the DPLTA, they could result in higher payments than anticipated. The potential distractions and costs related to any such litigation or proceedings may divert management’s attention away from successfully integrating Kloeckner’s business with ours and could result in additional financial exposure. A reduction in sales for any of the Detroit Three automakers, as well as additional or prolonged idling of production facilities in response supply chain constraints, has negatively impacted and could continue to negatively impact our business.

Risk Related to the Separation and Our Relationship with the Former Parent

We might not be able to engage in certain transactions and equity issuances following the distribution. Our ability to engage in equity transactions could be limited or restricted in order to preserve, for U.S. federal income tax purposes, the qualification of the distribution, together with certain related transactions, as a reorganization under Sections 355 and 368(a)(1)(D) of the Code. Even if the Distribution otherwise qualifies for tax-free treatment to the Former Parent’s shareholders under Section 355 of the Code, it may result in corporate-level taxable gain to the Former Parent if there is a 50% or greater change in ownership, by vote or value, of the common shares of Worthington Steel, the common shares of the Former Parent or the stock of a successor of either occurring as part of a plan or series of related transactions that includes the Distribution. Any acquisitions or issuances of Worthington Steel’s common shares or the Former Parent’s common shares within two years of the Distribution are generally presumed to be part of such a plan, although the Former

Parent may be able to rebut that presumption.

Under the Tax Matters Agreement that we entered into with the Former Parent on November 30, 2023, we are required to comply with the representations made in the private letter ruling the Former Parent received and in materials submitted to the IRS in connection therewith and to legal counsel in connection with the tax opinion the Former Parent received regarding the intended tax treatment of the Distribution and certain related transactions. The tax matters agreement also restricts our ability to take or fail to take any action if such action or failure to act could adversely affect the intended tax treatment. In particular, except in specific circumstances, in the two years following the Distribution, we are restricted from, among other things, (i) entering into any transaction pursuant to which all or a portion of our equity would be acquired, whether by merger or otherwise, and (ii) ceasing to actively conduct certain elements of our business.

These restrictions may limit for a period of time our ability to pursue certain transactions that we may believe to be in the best interests of our shareholders or that might increase the value of our business.

Risks Related to Owning Our Common Shares

The price of our common shares has fluctuated significantly and may continue to fluctuate significantly. The market price of our common shares has fluctuated significantly since the Separation, and may continue to fluctuate significantly due to a number of factors, many of which are beyond our control, including:

Stock markets in general have experienced volatility that has often been unrelated to the operating performance of a particular company. These broad market fluctuations may adversely affect the trading price of our common shares. These and other factors may cause the market price and demand for our common shares to fluctuate substantially, which may limit or prevent shareholders from readily selling our common shares and may otherwise negatively affect the liquidity of our common shares.

If we are unable to maintain effective internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports and the market price of our common shares may be negatively affected. As a public company, we are required to maintain internal controls over financial reporting and to report any material weaknesses in such internal controls. In addition, we are required to furnish annual management assessments of the effectiveness of our internal control over financial reporting and a report by our independent registered public accounting firm addressing these assessments pursuant to Section 404 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”). These reporting and other obligations may place significant demands on management, administrative and operational resources, including accounting systems and resources.

The process of designing, implementing, and testing the internal control over financial reporting required to comply with this obligation is time consuming, costly, and complicated. If we identify material weaknesses in our internal control over financial reporting, if we are unable to comply with the requirements of Section 404 of the Sarbanes-Oxley Act in a timely manner or to assert that our internal control over financial reporting is effective, or if our independent registered public accounting firm is unable to express an opinion as to the effectiveness of our internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports and the market price of our common shares could be negatively affected, and we could become subject to investigations by the stock exchange on which our securities are then listed, the SEC, or other regulatory authorities, which could require additional financial and management resources.

Certain provisions in our amended and restated articles of incorporation and amended and restated code of regulations, and of Ohio law, may prevent or delay an acquisition of us, which could decrease the trading price of our common shares. Our amended and restated articles of incorporation and amended and restated code of regulations contain, and Ohio law contains, provisions that are intended to deter coercive takeover practices and inadequate takeover bids and to encourage prospective acquirers to negotiate with the Board rather than to attempt an unsolicited takeover not approved by the Board. These provisions include, among others:

We believe these provisions will protect our shareholders from coercive or otherwise unfair takeover tactics by requiring potential acquirers to negotiate with the Board and by providing the Board with more time to assess any acquisition proposal. 18 Table of Contents We believe these provisions will protect our shareholders from coercive or otherwise unfair takeover tactics by requiring potential acquirers to negotiate with the Board and by providing the Board with more time to assess any acquisition proposal. These provisions are not intended to make us immune from takeovers. However, these provisions will apply even if the offer may be considered beneficial by some shareholders and could delay or prevent an acquisition that the Board determines is not in the best interests of us and our shareholders. These provisions may also prevent or discourage attempts to remove and replace incumbent directors.

General Risk Factors

Economic or Industry Downturns and Weakness

Our business is cyclical and weakness or downturns in the economy or certain industries could have an adverse effect on our business. If the domestic or global economies, or certain industry sectors of those economies that are key to our sales, contract or deteriorate, it could result in a corresponding decrease in demand for our products and negatively impact our results of operations and financial condition.

Volatility in the U.S. and worldwide capital and credit markets could negatively impact our end markets and result in reduced demand for our products, increased credit and collection risks and other adverse effects on our business. Inflation, elevated or volatile interest rates, stricter lending standards, geopolitical uncertainty and broader macroeconomic conditions may restrict access to capital or increase borrowing costs for us, our customers or our suppliers. If we, our customers or our suppliers are unable to access capital on acceptable terms, or at all, our ability to fund operations or growth initiatives, our suppliers’ ability to produce the materials we need, and our customers’ ability to purchase or timely pay for our products could be adversely affected. These conditions could adversely affect our business, financial condition and results of operations.

Tax Laws and Regulations

Tax increases or changes in tax laws or regulations could adversely affect our financial results. We are subject to tax and related obligations in the jurisdictions in which we operate or do business, including state, local, federal and non-U.S. taxes. The tax laws of the various jurisdictions in which we operate or do business often are complex and subject to varying interpretations. Tax authorities may challenge tax positions that we take or historically have taken and may assess taxes where we have not made tax filings or may audit the tax filings we have made and assess additional taxes. Some of these assessments may be substantial, and also may involve the imposition of penalties and interest.

In addition, governments could change their existing tax laws, impose new taxes on us or increase the rates at which we are taxed in the future. The payment of substantial additional taxes, penalties or interest resulting from tax assessments, or the imposition of any new taxes, could materially and adversely impact our results of operations and financial condition.

The Pillar Two Global Anti-Base Erosion rules issued by the Organization for Economic Cooperation and Development (“OECD”), a global policy forum, introduced a global minimum tax of 15% which would apply to multinational groups with consolidated financial statement revenue in excess of EUR 750 million. Nearly all OECD member jurisdictions have agreed in principle to adopt these provisions and numerous jurisdictions, including jurisdictions in which we operate, have enacted these rules effective January 1, 2024. However, the interpretation and application of these rules continue to evolve, and changes in guidance, enforcement or our facts and circumstances could affect our assessment. We will continue to monitor and refine our assessment as further guidance becomes available.

Legislation and Regulations

Certain proposed legislation and regulations may have an adverse impact on the economy in general and on our markets specifically, which may adversely affect our business. Our business may be negatively impacted by a variety of new or proposed legislation or regulations. For example, legislation and regulations proposing increases in taxation on, or heightened regulation of, greenhouse gas emissions may result in higher prices for steel, higher prices for utilities required to run our facilities, higher fuel costs for us and our suppliers and distributors, limitations on our ability to produce, use or sell certain products and other adverse impacts. To the extent that new legislation or regulations increase our costs, we may not be able to fully pass these costs on to our customers without a resulting decline in sales and adverse impact on our profits. Likewise, to the extent new legislation or regulations would have an adverse effect on the economy, our markets or the ability of domestic businesses to compete against foreign operations, we could also be adversely impacted. Likewise, to the extent new legislation or regulations would have an adverse effect 19 Table of Contents on the economy, our markets or the ability of domestic businesses to compete against foreign operations, we could also be adversely impacted.

Changes in healthcare laws or regulations may increase our employee benefit costs or administrative burden and adversely affect our results of operations. We provide healthcare benefits to eligible employees and are subject to laws and regulations governing employer-sponsored health plans, including requirements related to coverage, reporting, taxes, fees, privacy and plan administration. Changes in these laws or regulations, or increases in healthcare costs generally, could increase our employee benefit costs. This could require additional administrative resources or otherwise adversely affect our results of operations. In addition, our ability to attract and retain qualified employees could be adversely affected if we are unable to continue offering competitive healthcare benefits at costs that are acceptable to us.

Changes to global data privacy laws and cross-border transfer requirements could adversely affect our business and operations. Our business depends on the transfer of data between our affiliated entities, to and from our business partners, and with third-party service providers, which may be subject to global data privacy laws and cross-border transfer restrictions. For example, the European Union has implemented the General Data Protection Regulation (“GDPR”), which contains numerous requirements that must be complied with in connection with how we handle personal data related to our European-based operations and individuals. A number of U.S. states have introduced and passed legislation to expand data breach notification rules and to establish or expand consumer privacy protections, including protections similar to certain requirements under GDPR. While we take steps to comply with applicable legal requirements, the volatility and changes to such laws may impact our ability to effectively transfer data in support of our business operations. Compliance with such laws, or other regulatory standards, could also increase our cost of doing business and/or force us to change our business practices in a manner adverse to our business. In addition, violations of such laws, or other privacy regulations, may result in significant fines, penalties and damage to our brands and businesses which could, individually or in the aggregate, materially harm our business and reputation.

We have certain operations which are located outside of the U.S. that expose us to certain anti-corruption laws. We are subject to the Foreign Corrupt Practices Act (“FCPA”), which generally prohibits U.S. companies and their intermediaries from making corrupt payments or otherwise corruptly giving anything of value to foreign officials for the purpose of obtaining or keeping business or otherwise obtaining favorable treatment and requires companies to maintain adequate record-keeping and internal accounting practices. The FCPA applies to covered companies, individual directors, officers, employees, and agents. Under the FCPA, U.S. companies may be held liable for some actions taken by strategic or local partners or representatives. If we or our intermediaries fail to comply with the requirements of the FCPA, governmental authorities in the U.S. could seek to impose civil and/or criminal penalties. The other countries in which we operate may have similar or more stringent anti-corruption laws to which we must comply or risk civil and/or criminal penalties. The failure to comply with such laws may lead to negative effects on our business and financial condition.

Impairment Charges

Weakness or instability in the general economy, our markets or our results of operations could result in asset impairments, which would reduce our reported earnings and net worth. Economic conditions remain fragile in some markets and the possibility remains that the domestic or global economies, or certain industry sectors that are key to our sales, may deteriorate. If certain aspects of our operations are adversely affected by challenging economic and financial conditions, we may be required to record future impairments, including impairments or observable price adjustments related to equity securities, which would negatively impact our results of operations. If certain aspects of our operations are adversely affected by challenging economic and financial conditions, we may be required to record future impairments, which would negatively impact our results of operations.
