Metallus Inc. (MTUS) Business

Item 1. Business

Overview

Metallus Inc., ("we", "us", "our", the "Company" or "Metallus") was incorporated in Ohio on October 24, 2013, and became an independent, publicly traded company as the result of a spinoff from The Timken Company ("Timken") on June 30, 2014. In the spinoff, Timken transferred to us all of the assets and generally all of the liabilities related to Timken’s steel business.

We manufacture alloy steel, as well as carbon and micro-alloy steel, using electric arc furnace ("EAF") technology. Our portfolio includes special bar quality (“SBQ”) bars, seamless mechanical tubing (“tubes”), manufactured components such as precision steel components, and billets. Additionally, we manage raw material recycling programs, which are used internally as a feeder system for our melt operations and allow us to sell scrap not used in our operations to third parties. Our products and solutions are used in a diverse range of demanding applications in the following end-markets: industrial; automotive; aerospace & defense; and energy.

SBQ steel is made to restrictive chemical compositions and high internal purity levels and is used in critical mechanical applications. We make these products from nearly 100% recycled steel, using our expertise in raw materials to create high-quality specialty metal products. We focus on creating tailored products for our respective end-markets. Our engineers are experts in both materials and applications, so we can work closely with each customer to deliver flexible solutions related to our products as well as to their applications and supply chains.

The SBQ bar, tube, and billet production processes take place at our Canton, Ohio manufacturing location. This location accounts for all of the SBQ bars, seamless mechanical tubes and billets we produce and includes three manufacturing facilities: the Faircrest, Harrison, and Gambrinus facilities. Our production of manufactured components takes place at two downstream manufacturing facilities: Tryon Peak (Columbus, North Carolina) and St. Clair (Eaton, Ohio). Many of the production processes are integrated, and the manufacturing facilities produce products that are sold in all of our end-markets. As a result, investments in our facilities and resource allocation decisions affecting our operations are designed to benefit the overall business, not any specific aspect of the business.

Our annual melt capacity is approximately 1.2 million tons and our shipment capacity is approximately 0.9 million tons.

Operating Segments

We conduct our business activities and report financial results as one business segment. The presentation of financial results as one reportable segment is consistent with the way we operate our business and is consistent with the manner in which the Chief Operating Decision Maker ("CODM") evaluates performance and makes resource and operating decisions for the business as described above. Furthermore, the Company notes that monitoring financial results as one reportable segment helps the CODM manage costs on a consolidated basis, consistent with the integrated nature of our operations.

These products are custom-made in a variety of chemistries, lengths and finishes. Our metallurgical expertise and what we believe to be unique operational capabilities drive high-value solutions for industrial, automotive, aerospace & defense and energy customers. Our specialty metals are featured in a wide variety of end products including: gears; hubs; axles; crankshafts and motor shafts; oil country drill pipe; bits and collars; bearing races and rolling elements; bushings; fuel injectors; wind energy shafts; anti-friction bearings; artillery and mortar bodies; and other demanding applications where mechanical power transmission is critical to the end customer.

Manufactured Components. In addition to our customized steels, we also make precision components that provide us with the opportunity to further expand our market for bar and tube products and capture additional sales. These products provide customers, especially those in the automotive end-market, with ready-to-finish components that simplify vendor management, streamline supply chains and often cost less than other alternatives. We also produce products and provide supply chain solutions for the industrial, aerospace & defense and energy end-markets.

Sales and Distribution

Our sales force is made up largely of engineers that are backed by a team of metallurgists and other technical experts. While most of our products are sold directly to original equipment ("OE") manufacturers, a portion of our sales are made through authorized distributors and steel service centers, representing approximately 20% of net sales during 2025. The majority of our customers are served through individually negotiated price agreements.

Competition

The steel industry, both domestically and globally, is highly competitive and is expected to remain so. Maintaining high standards of asset reliability, product quality and customer service, while keeping production costs competitive, is essential to our ability to compete with domestic and foreign manufacturers of alloy steel and mechanical components. For bar products less than 6-inch in diameter, the primary competitor is foreign-owned domestic producer Gerdau Special Steel North America (a unit of Brazilian steelmaker Gerdau, S.A). For bar products up to 9-inch in diameter, domestic producers Steel Dynamics, Inc. and Nucor Corporation (in some cases up to 10-inch) are our principal competitors. For very large bars from 10 to 16 inches in diameter, offshore producers as well as specialty forging companies in North America such as Scot Forge and Frisa are the primary competitors. For seamless mechanical tubing, offshore producers such as Tenaris, S.A., Vallourec, S.A. and TMK Group are our primary competitors, as well as the foreign-owned domestic producer ArcelorMittal Tubular Products (a unit of Luxembourg-based ArcelorMittal, S.A.). We also provide unique manufactured steel products and supply chain solutions to our customers in the industrial, automotive, aerospace & defense and energy end-markets. Manufactured component competitors include both integrated and non-integrated component producers.

Lead Time

The lead time for our products varies based on product type and specifications. As of the date of this filing, lead times for bar extend to mid-second quarter and tube products currently extend to mid-third quarter.

Raw Materials

The principal raw materials that we use to manufacture steel are recycled scrap metal, chrome, nickel, molybdenum oxide, vanadium and other alloy materials. Raw materials comprise a significant portion of the steelmaking cost structure and are subject to price and availability changes due to global demand fluctuations and local supply limitations. Proper selection and management of raw materials can have a significant impact on procurement cost, steelmaking energy costs, mill productivity and ability to adapt to supply chain constraints. In addition to accessing scrap and alloys through the open market, we have established a scrap return supply chain with many of our customers. This part of our business leverages our knowledge of the raw material supply industry and an extensive network of relationships that result in steady, reliable supply from our raw material sources.

In the ordinary course of business, we are exposed to the volatility of the costs of our raw materials. For example, the impact of global conflicts could exacerbate inflationary pressures throughout the global economy and lead to potential market disruptions, such as significant volatility in commodity prices and supply chain disruptions. Although our business has not been materially impacted by current conflicts to date, it is difficult to predict the extent to which our operations, or those of our suppliers, will be impacted in the future.

Whenever possible, we manage our exposure to commodity risks primarily through the use of supplier pricing agreements that enable us to establish the purchase prices for certain inputs that are used in our manufacturing process. We also utilize raw material and energy surcharge mechanisms when pricing products to our customers.

There are two components of our raw material surcharge. One component is related to the scrap metal content in our finished product and is based on the published No. 1 busheling scrap index. The other component is related to alloy material content in our finished product and is based on published prices for nickel, molybdenum, vanadium, chrome, and manganese. The energy surcharge is only applicable when the price of natural gas exceeds a certain dollar amount per MMBtu or when the price of electricity exceeds a certain amount per MWH.

Our surcharge mechanisms are designed to mitigate the impact of increases or decreases in raw material costs, although generally with a lag effect. This timing effect can result in raw material spread whereby costs can be over- or under-recovered in certain periods. While the surcharge generally protects gross profit, it has the effect of diluting gross margin as a percent of sales.

Defense Contract

On February 27, 2024, the Company entered an agreement with the United States Army ("U.S. Army"). The agreement provides for $99.75 million in funding to support the U.S. Army's mission of increasing munitions production for national security in the

upcoming years. The agreement supports the commissioning of two major assets: a continuous bloom reheat furnace and a roller hearth heat treat furnace. Through December 31, 2025, the Company received $85.6 million in funding related to this agreement and recorded the funding as a current liability on the Consolidated Balance Sheets and as investing within the Consolidated Cash Flows. There was $81.3 million in capital spending related to assets associated with this agreement in 2025.

For further details, refer to “Note 2 - Significant Accounting Policies” in the Notes to the Consolidated Financial Statements.

Faircrest Melt Shop Unplanned Downtime

During the second half of 2022, the Faircrest melt shop experienced unplanned operational downtime. The company recognized insurance recoveries of $31.3 million in 2023 related to the unplanned downtime and received $20.0 million in January 2024. The 2022 insurance claims were closed in the first quarter of 2024.

For further information related to previous insurance recoveries, refer to "Note 6 - Other (Income) Expense, net" in the Notes to the Consolidated Financial Statements for additional information.

Environmental Matters and Governmental Regulations

We consider compliance with environmental regulations and environmental sustainability a key strategic focus area and integral to our responsibility as a good corporate citizen. All our domestic steel making and processing operations, and our water treatment plant, have obtained and maintain ISO 14001 certification.

We believe we have established appropriate reserves to cover our environmental expenses. We have a well-established environmental compliance audit program that measures performance against applicable laws as well as against internal standards that have been established for all facilities.

We have been identified as a potentially responsible party under the Clean Air Act ("CAA"), Clean Water Act ("CWA"), Toxic Substances Control Act ("TSCA"), the Resource Conservation and Recovery Act ("RCRA"), as well as other laws. We continue to monitor regulations relevant to our Company to ensure we remain compliant. This includes, but is not limited to, regulations such as the CAA, CWA, TSCA, and the RCRA.

Additionally, we continue to monitor any future carbon regulation. To date, the U.S. Congress has not legislated carbon constraints on businesses. It is difficult to predict the possible effect of compliance with future requirements that differ from existing ones both domestically and internationally.

From time to time, we may be a party to lawsuits, claims or other proceedings related to environmental matters and/or receive notices of potential violations of environmental laws and regulations from the EPA and similar state or local authorities. We recorded reserves for such environmental matters of $0.2 million and $0.4 million as of December 31, 2025 and 2024, respectively. Accruals related to such environmental matters represent management’s best estimate of the fees and costs associated with these matters. Although it is not possible to predict with certainty the outcome of such matters, management believes the ultimate disposition of these matters should not have a material adverse effect on our consolidated financial position, results of operations or cash flows.
