Previous wording

Our profitability is dependent upon the historically volatile market prices of steel, scrap metal and iron ore. We experience direct impacts of steel price fluctuations through customer sales, as well as direct and indirect impacts of scrap metal and iron ore price fluctuations through third-party sales and the impacts that movements in scrap metal and iron ore prices have on steel prices. As described elsewhere in this report, the prices of steel, scrap metal and iron ore have fluctuated significantly in the recent past, and these pricing shifts are unpredictable and affected by factors beyond our control, including: international demand for, and the impact of higher rates of inflation on, raw materials used in steel production; availability of scrap metal substitutes such as pig iron; commodity price speculation; rates of global economic growth, especially construction and infrastructure activity that requires significant amounts of steel; changes in the levels of economic activity in the U.S., China, India, Europe and other industrialized or developing economies, including as a result of geopolitical conflicts or otherwise; changes in China’s emissions policies and environmental compliance enforcement practices; changes in the production capacity, production rate and inventory levels of other steel producers, distributors, iron ore suppliers and scrap metal processors and traders; changes in trade laws; volumes of unfairly traded imports; imposition or termination of duties or tariffs, including tariffs and retaliatory tariffs that have recently been and may in the future be instituted following the recent change in U.S. presidential administrations, which among other things may affect our cross-border shipments, import and export controls, and other trade barriers impacting the steel and iron ore markets; climate change and other weather-related disruptions, infectious disease outbreaks or natural disasters that may impact the global supply of steel, scrap metal or iron ore; and the proximity, capacity and cost of infrastructure and transportation.

Current wording

Our profitability is dependent upon the historically volatile market prices of steel, scrap metal and iron ore. We experience direct impacts of steel price fluctuations through customer sales, direct impacts of scrap metal price fluctuations through customer sales and supplier purchases, and indirect impacts from movements in scrap metal and iron ore prices that influence steel prices.

Our revenues, therefore, vary in accordance with the prices of the products we sell. During 2024, for example, we experienced lower average selling prices for our steel products as compared to 2023 due to the impact from lower index pricing, which resulted in lower revenues. In addition, we had lower sales volumes in 2024, which also contributed to lower revenues. To the extent that commodity prices, including the HRC price, coated and other specialty steel prices, international steel prices and scrap metal prices, significantly decline for an extended period, we may have to further revise our operating plans, including curtailing production, reducing operating costs and deferring capital expenditures. As a result, we also may have to record impairments on our goodwill, intangible assets, long-lived assets and/or inventory. Sustained lower prices also could cause us to further reduce existing mineral reserves if certain reserves can no longer be economically mined or processed at prevailing prices. Particularly during periods of increased inflation resulting in higher input costs, we may be unable to decrease our costs in an amount sufficient to offset reductions in revenues and may incur losses. These events could have a material adverse effect on us.

The largest end user for our steel products is the automotive industry in North America. Beyond these direct sales to the automotive industry, we make additional sales to distributors and converters, which may ultimately resell some of that volume to the automotive market. In addition to the magnitude of our exposure to the automotive industry, we face risks arising from our relative concentration of sales to certain specific automotive manufacturers, and our sales volumes and revenues may be adversely affected if we are unable to renew our fixed price contracts with one or more significant automotive customers or if those customers choose to move certain portions of their parts business to alternate suppliers. Automotive production and sales are cyclical and sensitive to general economic conditions and other factors, including interest rates, consumer credit, spending and preferences, and supply chain disruptions. If automotive production and sales decline, whether due to consumers facing reduced purchasing power caused by inflation, higher interest rates or otherwise, our sales and shipments to the automotive market are likely to decline in a corresponding manner. Adverse impacts that we may sustain as a result include, without limitation, lower margins because of the need to sell our steel to less profitable customers and markets, higher fixed costs from lower steel production if we are unable to sell the same amount of steel to other customers and markets, and lower sales, shipments, pricing and margins generally as our competitors face similar challenges and compete vigorously in other markets that we serve. These adverse impacts could negatively affect our revenues, financial results and cash flows.

Moreover, despite our position as a leading North America-based flat-rolled steel producer, competition for automotive business has intensified in recent years, as steel producers and companies producing alternative materials have focused their efforts on capturing and/or expanding their market share of automotive business because of less favorable conditions in other markets for steel and other metals, including commodity products. As a result, the potential exists that we may lose market share to existing or new entrants or that automotive manufacturers will take advantage of the intense competition among potential suppliers during periodic contract renewal negotiations to pressure our pricing and margins in order for us to maintain or expand our market share with them, which could negatively affect our revenues, financial results and cash flows.

Global steelmaking overcapacity and overproduction, as well as steel imports, could lead to lower or more volatile global steel prices, directly or indirectly impacting our profitability.

Previous wording

Significant existing global steel capacity and new or expanded production capacity in recent years could potentially cause capacity to exceed demand globally. Although certain American steel producers have shut down production capacity, certain of our competitors have announced and are moving ahead with plans to develop new steelmaking capacity in the near term. In addition, certain foreign competitors, which may have cost advantages due to being owned, controlled or subsidized by foreign governments, have substantially increased their steelmaking capacity and/or production in the last few years and in some instances appear to have targeted the U.S. market for imports. The risk of even greater levels of imports may continue, depending upon foreign market and economic conditions, changes in trade agreements and treaties, laws, regulations or government policies affecting trade, the ability of foreign producers to circumvent U.S. trade sanctions and policy (including in the markets for electrical steels), the value of the U.S. dollar relative to other currencies and other variables beyond our control. In addition, higher sustained market prices of steel and iron ore products could cause new producers to enter the market or existing producers to further expand productive capacity, which could in turn lead to lower steel prices and increasing prices of steelmaking inputs, such as scrap metal. Excess steel and iron ore supply combined with reduced global steel demand and increased imports could also lead to lower steel and iron ore prices. Downward pressure on steel and/or iron ore prices could have an adverse effect on our results of operations, financial condition and profitability.

Sales and operations for a majority of our customers are sensitive to general economic conditions in the North American automotive, housing, construction, appliance, energy, defense and other industries. Some of our customers are highly leveraged. If there is a sustained weakening of current economic conditions, whether because of operational, cyclical, supply chain or other issues, including inflationary pressures, higher interest rates or an infectious disease outbreak, it could cause customers to reduce, delay or cancel their orders with us, impact significantly the creditworthiness of our customers, and lead to other financial difficulties or even bankruptcy filings by our customers. Failure to receive payment from our customers for products that we have delivered could adversely affect our results of operations, financial condition and liquidity. The concentration of customers in a specific industry, such as the automotive industry, may increase our risk because of the likelihood that circumstances may affect multiple customers at the same time. Such events could cause us to experience lost sales or losses associated with the potential inability to collect all outstanding accounts receivable as well as reduced liquidity. Similarly, certain of our key vendors have recently suffered, and from time to time may continue to suffer, financial hardship, including bankruptcy. Such vendors could face operational disruption or even be forced to liquidate, which could result in such vendors defaulting on their obligations to us or in our inability to secure replacement materials or services on a timely basis, or at all, or cause us to incur increased costs to do so. Such events could adversely impact our continuity of operations, financial results and cash flows.

In recent years, the U.S. government has altered its approach to international trade policy, both generally and with respect to matters directly and indirectly affecting the steel industry, including by undertaking certain unilateral actions affecting trade, renegotiating existing bilateral or multilateral trade agreements, and entering into new agreements or treaties with foreign countries. For example, in March 2018, the U.S. government issued a proclamation pursuant to Section 232 imposing a 25% tariff on imported steel. These Section 232 tariffs were imposed on national security grounds and addressed imported steel that was being unfairly traded by certain foreign competitors at artificially low prices. In retaliation against the Section 232 tariffs, the European Union subsequently imposed its own tariffs against certain steel products and other goods imported from the U.S. Following the November 2020 U.S. presidential election, negotiations between the U.S. government and other governments resulted in revisions to these measures. For example, the U.S. government agreed to modified tariff rate quota systems with each of the European Union, Japan and the United Kingdom that allowed more imports from those trading partners to enter the U.S. market free of Section 232 tariffs. However, in early 2025, the U.S. government announced that the 25% Section 232 tariffs on steel imports would be re-imposed without exemptions and exclusions, beginning in March 2025. Even so, as has occurred in the past, the U.S. government may later determine to negotiate exemptions and exclusions from Section 232 tariffs with certain trading partners. And if the Section 232 measures are removed, modified or substantially weakened, whether through legal challenge, legislation, further executive action or otherwise, imports of foreign steel would likely increase and steel prices in the U.S. would likely fall, which could materially adversely affect our revenues, financial results and cash flows.

Subsequently, in June 2025, the Section 232 steel tariffs were generally increased to 50%. During 2025, Section 232 tariffs were also applied to certain products derived from steel as part of the U.S. Department of Commerce Section 232 steel inclusions process. Furthermore, in 2025, the Canadian government imposed a 25% tariff on imported steel regardless of country of origin

In addition, during 2020, the USMCA was implemented among the U.S., Mexico and Canada in place of the North American Free Trade Agreement. Because all our steel manufacturing facilities are located in North America and one of our principal markets is automotive manufacturing in North America, we believe that the USMCA has the potential to positively impact our business by incentivizing automakers and other manufacturers to increase manufacturing production in North America and to use North American steel. However, it is difficult to predict the implications of changes in trade policy and, therefore, whether the USMCA or other new or renegotiated trade agreements, treaties, laws, regulations or policies that may be implemented by the U.S. government, or otherwise, will have a beneficial or detrimental impact on our business and our customers’ and suppliers’ businesses. Adverse effects could occur directly from a disruption to trade and commercial transactions and/or indirectly by adversely affecting the U.S. economy or certain sectors of the economy, impacting demand for our customers’ products and, in turn, negatively affecting demand for our products. Important links of the supply chain for some of our key customers, including automotive manufacturers, could be negatively impacted by the USMCA or other new or renegotiated trade agreements, treaties, laws, regulations or policies.

While we may currently benefit from certain antidumping and countervailing duty orders, any such relief is subject to periodic reviews and challenges, which can result in revocation or modification of the orders or reduction of the duties. Currently, there are ongoing antidumping and countervailing duty investigations involving imports of corrosion-resistant steel into the U.S. from various countries, including Canada, Mexico, Brazil, Australia, the Netherlands, South Korea, Taiwan, Turkey, Vietnam and the United Arab Emirates. The outcomes of those investigations are uncertain and could adversely affect the competitiveness and viability of our U.S. and/or Canadian corrosion-resistant steel businesses. Following the recent change in U.S. presidential administrations, the U.S. government may seek to alter the USMCA and has imposed and may in the future impose new or additional tariffs on goods imported into the U.S. (including steel or critical production inputs), which has led to and could in the future lead to other countries imposing or threatening to impose retaliatory tariffs on exports of American-made products (including steel) to those countries or other retaliatory efforts, such as restricting exports of critical production inputs to the U.S. In addition, previously granted petitions for trade relief may not be successful or fully effective at preventing harm from subsidized and dumped imports into the U.S. Any of these actions and their direct and indirect impacts could materially adversely affect our revenues, financial results and cash flows.

As a supplier on public procurement projects, including projects that may arise out of proposed or recently enacted governmental legislation regarding infrastructure investments such as the Infrastructure Investment and Jobs Act of 2021, we may be subject to certain stringent regulations that may present compliance challenges or may increase the costs of securing certain business. For example, in order to remain eligible for DOE funding, our major Butler and Middletown capital projects are subject to extensive U.S. government and DOE-specific regulations with which we must comply, including with respect to restrictions related to the use of foreign contractors and workers. Also, the U.S. government has rights to, and imposes restrictions on, intellectual property from the projects. The additional burdens and restrictions imposed by these regulations increase our costs, may limit our operational and contracting flexibility, and may disincentivize certain technology providers or other vendors from working with us. We may also be indirectly affected through regulatory changes that impact our customers, which in turn could reduce the quantity of our products they demand, adversely impact the terms upon which they purchase or the prices for our products they are willing to pay. Regulatory changes that impact our suppliers, such as any changes in labor or environmental standards in China, could decrease the availability of products or services they sell to us or could increase the price they demand for products or services they sell to us.

While we currently expect the U.S. Federal Reserve to lower interest rates during 2026, decisions regarding the trajectory of future interest rates are uncertain, and there is risk that interest rates could be maintained or even increased. Higher-than-expected interest rates would increase the amount of cash we would need to allocate to servicing the interest expense on our debt for so long as we have an outstanding balance drawn under our ABL Facility.

Previous wording

Our ability to make scheduled payments on the principal, premium, if any, and interest on our debt, or to refinance our debt obligations, depends on our ability to generate cash in the future and our financial condition and operating performance, which are subject to prevailing economic and competitive conditions and to certain financial, business and other factors beyond our control, as described elsewhere in this “Risk Factors” section. If we are unable to service our debt obligations, we could face substantial liquidity problems and we may be forced to reduce or delay investments, capital expenditures and share repurchases, or to sell assets, seek additional capital, including additional secured or unsecured debt, or restructure or refinance our debt, and we may be unable to continue as a going concern. We may be unable to consummate any proposed asset sales or recover the carrying value of these assets, and any proceeds may not be adequate to meet any debt service obligations then due. Any of these examples potentially could have a material adverse impact on our results of operations, profitability, shareholders’ equity and capital structure. In addition, a failure to comply with any applicable covenants in the instruments governing our debt could result in an event of default that, if not cured or waived, would have a material adverse effect on us.

Previous wording

Our level of indebtedness could have further consequences, including, but not limited to, increasing our vulnerability to adverse economic or industry conditions, placing us at a competitive disadvantage compared to other businesses in the industries in which we operate that are not as leveraged and that may be better positioned to withstand economic downturns and recessionary environments, limiting our flexibility to plan for, or react to, changes in our businesses and the industries in which we operate, and requiring us to refinance all or a portion of our existing debt. We may not be able to refinance on commercially reasonable terms or at all, and any refinancing of our debt could be at higher interest rates and may require us to comply with more onerous covenants, making it more difficult to obtain surety bonds, letters of credit or other financial assurances that may be demanded by our vendors or regulatory agencies, particularly during periods in which credit markets are weak. In addition, our cost of financing or refinancing, access to the capital markets, and the terms under which we purchase goods and services could be adversely affected if credit ratings agencies downgrade our ratings, whether due to factors specific to our business or debt profile, a prolonged cyclical downturn in the steel, scrap metal and mining industries or macroeconomic trends (such as global or regional recessions), increases in pension and OPEB obligations, adverse impacts of inflation and high interest rates, or trends in credit and capital markets more generally. A portion of our borrowing capacity and any outstanding indebtedness under our ABL Facility bears interest at a variable rate based on SOFR. To the extent these interest rates increase, our interest expense will increase. Restricted access to capital markets and/or increased borrowing costs could have an adverse effect on our results of operations, cash flows, financial condition and liquidity.

We are from time to time subject to various lawsuits, claims, arbitrations or governmental proceedings relating to commercial and business disputes, antitrust claims, environmental matters, government investigations, occupational or personal injury claims, property damage, labor and employment matters, or suits involving legacy operations and other matters. For example, certain of our subsidiaries have been named in lawsuits claiming exposure to asbestos, many of which have been dismissed and/or settled for non-material amounts. Nevertheless, it is likely that similar types of claims will continue to be filed in the future, and we could experience material adverse judgments or incur significant costs to defend such claims or any other existing and future lawsuits, claims, arbitrations or governmental proceedings, including those discussed in Part I - Item 3. Legal Proceedings, which could adversely affect our results of operations, cash flows, financial condition and liquidity. The insurance we maintain may not cover certain claims and, even when coverage applies, it may not be adequate to protect us in the event of significant claims.

Current wording

Our operating expenses could increase significantly if the prices of raw materials, electrical power, fuel or other energy sources rise.

Previous wording

Our operations require significant use of energy, water and raw materials. Although we are largely self-sufficient in iron ore and partially self-sufficient in coke, metallurgical coal and scrap metal, we are wholly or partially dependent on third-party suppliers for certain critical raw materials and production inputs, including industrial gases, graphite electrodes, chrome, zinc, coke, metallurgical coal, scrap metal, fluxing compounds and other alloys. Prices for electricity, natural gas, diesel fuel, oils and raw materials can fluctuate widely with availability and demand levels from other users, including fluctuations caused by the impact of inflationary pressures, supply chain constraints, infectious disease outbreaks and geopolitical conflicts. For example, increased electricity demand to the grid in response to physical climate-related risks, adverse or extreme weather events and electrification of the economy could adversely impact energy prices. During periods of peak usage, although some operations have contractual arrangements in place whereby they receive certain offsetting payments in exchange for electricity load reduction, supplies of energy and raw materials in general may be curtailed and we may not be able to purchase them at historical rates. A disruption in the transmission of energy, inadequate energy transmission infrastructure, or the termination of any of our energy supply contracts could interrupt our energy supply and adversely affect our operations. While we have some long-term contracts with electrical, natural gas and raw material suppliers, we are exposed to fluctuations in energy, natural gas and raw material costs that can affect our production costs. We regularly enter into market-based pricing supply contracts for electricity, natural gas and diesel fuel for use in our operations. Those contracts expose us to price increases in energy costs, which could cause our profitability to decrease significantly. In addition, U.S. public utilities may impose rate increases and/or pass through additional capital and operating cost increases to their customers related to new or pending U.S. environmental regulations or other charges that may require significant capital investment and/or use of cleaner fuels in the future. New or revised regulations or other government actions related to GHG emissions standards could result in rate and/or cost increases from U.S. public utilities, which could significantly increase the costs of operating our manufacturing and mining facilities. Although we regularly monitor and from time to time challenge rate cases initiated by these utilities or other sources seeking to increase the amounts that our facilities must pay for electricity, natural gas or water, there is no assurance that our challenges will be successful in reducing or eliminating proposed rate and/or cost increases.

Disruption of the rail, trucking, lake and other waterway transportation services because of weather-related problems, including ice and winter weather conditions on the Great Lakes or St. Lawrence Seaway, climate change, strikes, lock-outs, driver shortages and other disruptions in the trucking industry, train crew shortages or other rail network constraints, infectious disease outbreaks, or other events and lack of alternative transportation options could impair our ability to move products internally among our facilities and to supply products to our customers at competitive rates or in a timely manner and, thus, could adversely affect our operations, revenues, margins and profitability. For example, if the vessel shipping season on the Great Lakes were to be interrupted or shortened as compared to historical levels, whether due to extended winter conditions, operational failure of critical shipping locks or otherwise, our ability to transport iron ore pellets to our steel mills could be adversely affected, resulting in potential operational disruptions and reduced production volumes. Further, dredging issues and environmental changes, particularly at Great Lakes ports or along navigable rivers, could adversely impact our ability to move certain of our products or result in higher freight rates. Similarly, we depend on third-party transportation services for delivery of raw materials and other production inputs to us, and failures or delays in delivery would have an adverse effect on our ability to maintain steady-state production and processing operations to meet customer obligations.

Previous wording

Most of our mines and production and processing facilities have been in operation for several decades, and the equipment is aged, requiring that we continually and successfully implement extensive and costly maintenance practices, programs and upgrades, which may take longer or be more costly than expected. From time to time, we undertake capital projects to enhance, expand, maintain or upgrade our production, mining and processing capabilities. For example, we are engaged in major initiatives at each of our Butler and Middletown facilities to leverage DOE funding to complete capital projects intended to increase our competitiveness and reduce GHG emissions relating to our steelmaking operations. In addition, we are developing an electrical transformer production plant at our former Weirton tinplate facility. Our ability to complete these and other capital projects that we may undertake on time and on budget and achieve the anticipated production volumes, revenues or otherwise realize acceptable returns is subject to a number of risks, many of which are beyond our control, including a variety of market, operational, funding, permitting and labor-related factors. Further, the cost to implement any given capital project may prove to be greater or may take more time than originally anticipated, including due to supply chain issues that may be experienced by our vendors, and the scope of a capital project may expand or otherwise be modified. Capital projects undertaken at existing active operations, such as Butler and Middletown, may also interrupt production capabilities, which could have an adverse effect on costs and profitability. Inability to achieve the expected results from the implementation of our capital projects, incurring unanticipated costs or delays, or the inability to meet contractual obligations could adversely affect our results of operations, future earnings and cash flow generation.

Factors that could cause production disruptions could include adverse weather conditions influenced by climate change or otherwise (such as severe winter weather, tornadoes, floods, temperature extremes and the lack of availability of process water due to drought) and natural and human-caused disasters, lack of adequate raw materials, energy or other supplies, and infectious disease outbreaks. Additional factors that could adversely impact production and operations at our mining facilities include tailings dam failures, pit wall failures or ground subsidence, unanticipated geological conditions, including variations in the amount of overburden overlying deposits of iron ore and metallurgical coal, and processing changes.

Given our status as a critical supplier of steel to U.S. business and defense interests, we may be the target of malicious cyber activities sponsored by nation-state actors, including the Russian and Chinese governments or other state actors, as described in threat advisories periodically issued from time to time by the U.S. Cybersecurity & Infrastructure Security Agency. For example, U.S. government agencies have warned that certain state-sponsored actors are pre-positioning themselves within critical infrastructure networks to enable potential disruption during a future geopolitical crisis. Cybersecurity threat actors also may attempt to exploit vulnerabilities through software, including software commonly used by companies in cloud-based services and bundled software. Though we have controls in place and regularly conduct employee training, we cannot provide assurance that a cybersecurity incident or cyberattack will not occur or cause damage or business interruption. Furthermore, despite our efforts to audit certain critical vendors’ information security controls, significant risk may remain with respect to security measures employed by third-party service providers (including risks from software supply chain compromises or vulnerabilities introduced through vendor software updates), which may ultimately prove to be ineffective at countering threats.

Previous wording

Failures of our IT systems, whether caused maliciously or inadvertently, may result in the disruption of our business processes, or in the unauthorized release of sensitive, confidential, personally identifiable or otherwise protected information, or result in the corruption of data, or a cybersecurity incident, each of which could adversely affect our businesses. For example, cybersecurity vulnerabilities or other cybersecurity incidents could result in an interruption of the functionality of our automated manufacturing, operating, or health, safety and environmental systems, which, if compromised, could cease, threaten, delay or slow down our ability to produce or process steel or any of our other products for the duration of such interruption or lead to unanticipated health, safety or environmental incidents. This, in turn, could result in reputational harm and lead to litigation, including individual claims or class actions, commercial litigation, administrative, civil or criminal investigations or actions, regulatory intervention and sanctions or fines, investigation and remediation costs, and may adversely affect our employees, results of operations, financial condition and cash flows. In addition, any compromise of the security of our IT systems could result in a loss of confidence in our security measures or in the unauthorized release of third-party confidential information stored in our systems, which could subject us to litigation, regulatory investigations and negative publicity that could adversely affect our reputation and expose us to third-party liability. Our customers, suppliers and vendors may also access or store certain of our sensitive information on their IT systems, which, if breached, attacked or accessed by unauthorized persons, could likewise expose our sensitive information and adversely impact our businesses. Furthermore, as cybersecurity threats continue to evolve and may become more sophisticated, including in connection with the ongoing development 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. The amount of insurance coverage we maintain and require our vendors to maintain may be inadequate to cover claims or liabilities resulting from cybersecurity incidents and attacks, and there is no guarantee that such coverage will continue to be available on commercially reasonable terms or at all.

Previous wording

If faced with overcapacity in the market, regulatory challenges or other adverse conditions, we may seek to rationalize manufacturing and production assets through sales, temporary shutdowns, indefinite idles or facility closures. If we indefinitely idle or permanently close any of our facilities or mines, our production and revenues would be reduced unless we were able to increase production at our other facilities or mines in an offsetting amount, which may not be possible, and could result in customers responding negatively by taking current or future business away from us if we seek to transition production to a different facility. Alternatively, we could fail to meet customer specifications at the facilities to which products are transitioned, resulting in customer dissatisfaction or claims. To the extent an idled or closed facility formerly supplied critical inputs to our upstream production facilities, we may need to secure alternate sources for such critical inputs, the cost and availability of which may be uncertain. For example, during 2024, we indefinitely idled our Weirton, West Virginia tinplate production facility, which caused us to recognize costs of approximately $210 million in respect of employee-related costs, asset impairments and exit costs.
