Metallus (NYSE: MTUS) grows Q1 2026 earnings with strong liquidity

Rhea-AI Filing Summary

Metallus Inc. reported stronger first-quarter 2026 results, with net sales of $308.3 million, up 9.9% from $280.5 million a year earlier. Net income rose to $5.4 million from $1.3 million, and diluted earnings per share increased to $0.13 from $0.03.

Gross profit improved to $25.1 million, helped by higher shipments, better price/mix and raw material spread, partly offset by increased manufacturing costs. Aerospace & defense and industrial demand were key contributors, while energy softened.

Cash and cash equivalents were $104.0 million, with total liquidity of $374.7 million and no debt outstanding under the $400 million credit facility. Operating cash outflow of $26.9 million reflected higher working capital and pension contributions. Metallus continued investing, with $24.7 million of capital expenditures and ongoing U.S. Army–funded projects, and repurchased 0.3 million shares for $4.3 million.

Insights

Equity analyst

Q1 2026 shows higher profit, solid balance sheet, and ongoing investment.

Metallus grew Q1 2026 net sales to $308.3 million, up 9.9% year over year, as shipments and surcharges increased. Net income improved to $5.4 million versus $1.3 million, with gross profit rising to $25.1 million on better price/mix and raw material spread.

Margins benefited from stronger aerospace & defense and industrial volumes, while higher utilities, labor from the new USW contract, and optimization project costs raised manufacturing expenses. SG&A fell 8.6% to $22.2 million, supporting the earnings step-up.

Liquidity remains a highlight: total liquidity was $374.7 million at March 31, 2026, with $104.0 million in cash and no borrowings under a $400.0 million credit line. Operating cash outflow of $26.9 million mainly reflected inventory build, receivables growth, and $19.8 million in pension contributions. The company continued funding $24.7 million of capital spending, largely tied to a $99.75 million U.S. Army agreement, and repurchased 0.3 million shares for $4.3 million.

electric arc furnace, Non-GAAP financial measures, surcharges, share repurchase program, +1 more

5 terms

electric arc furnace technical

"We manufacture alloy steel, as well as carbon and micro-alloy steel, using electric arc furnace ("EAF") technology."

An electric arc furnace is an industrial furnace that melts scrap metal or direct-reduced iron by creating intense heat from an electric arc between electrodes, like a giant, high-powered electric oven that turns metal pieces into molten steel. Investors care because it determines a steelmaker’s energy costs, flexibility to use recycled material, and greenhouse gas footprint—factors that affect profitability, raw-material exposure, and regulatory or public-pressure risks.

Non-GAAP financial measures financial

"Non GAAP (1) Financial Measures: An analysis of our net sales by end-market, adjusted to exclude surcharges"

Non-GAAP financial measures are numbers companies use to show their financial performance that exclude certain expenses or income. They help investors see how the company might perform without one-time costs or other unusual items, giving a different perspective from official reports. However, since they can be adjusted, they don’t always tell the full story and should be looked at alongside standard financial figures.

surcharges financial

"net sales adjusted to exclude surcharges provides management and investors clarity of our core pricing and results."

share repurchase program financial

"authorized a share repurchase program under which the Company may repurchase up to $50.0 million of its outstanding common shares."

A share repurchase program is when a company buys back its own shares from the marketplace. This reduces the total number of shares available, which can increase the value of each remaining share and signal confidence in the company's prospects. For investors, it often suggests that the company believes its stock is undervalued or that it has extra cash to return to shareholders.

net periodic benefit cost financial

"The components of net periodic benefit cost (income) for the three months ended March 31, 2026 were as follows"

Net periodic benefit cost is the annual amount a company records on its income statement to reflect the cost of promised retirement benefits (like pensions and retiree health plans). Think of it as the yearly tally that combines the new cost of benefits earned by workers, the effect of interest and investment returns on plan savings, and adjustments for past changes — it matters because it directly affects reported profit and signals how well-funded those long-term promises are, which can influence cash needs and investor risk assessments.

Notes to Unaudited Consolidated Financial Statements

(dollars in millions, except per share data)

Note 1 - Basis of Presentation

The accompanying unaudited Consolidated Financial Statements have been prepared by Metallus Inc. (the “Company” or “Metallus”) in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) and disclosures considered necessary for a fair presentation have been included. For further information, refer to Metallus' audited Consolidated Financial Statements and Notes included in its Annual Report on Form 10-K for the year ended December 31, 2025.

Note 2 - Recent Accounting Pronouncements

Adoption of New Accounting Standards

The Company did not adopt any new Accounting Standard Updates (“ASU”) in the first quarter of 2026.

Accounting Standards Issued But Not Yet Adopted

The Company has considered the recent ASU's issued by the Financial Accounting Standards Board summarized below:

Standard Adopted		Description		Effective Date		Impact
ASU 2024-03, Disaggregated Expenses		The standard enhances the detail of expenses presented in the income statement including items such as: (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization.		Annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027, with early adoption permitted.		The Company is currently evaluating the impact of the adoption of this ASU on its disclosures. The standard has no impact on the results of operations and financial condition.

Note 3 - Segment Reporting

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 the Company operates its 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. Our CODM is our Chief Executive Officer. 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 the operations. The CODM uses Net Income (Loss), as reported on our Consolidated Statements of Operations, in evaluating performance of the Company and determining how to allocate resources of the Company as a whole. As the CODM evaluates performance on a consolidated basis, all required financial segment information is included in our consolidated financial statements.

Note 4 - Government Funding

On February 27, 2024, the Company entered into 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. For the quarter ended March 31, 2026 and 2025, the Company received $5.9 million and $12.9 million, respectively, 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. For the quarter ended March 31, 2026 and 2025, there was $18.3 million and $13.9 million, respectively, in capital spending related to assets associated with this agreement.

In April 2026, the Company received an additional $9.5 million in government funding related to this agreement.

Note 6 - Restructuring Charges

During the third quarter of 2025, the Company offered an exit incentive program to certain retirement-eligible employees at the Company's corporate headquarters and manufacturing facilities to support succession planning and continue execution of the Company's sustainable profitable growth strategy. As a result, the Company recorded a $2.7 million restructuring reserve associated with the program. These charges primarily consist of severance and employee-related benefits.

Metallus recorded reserves for such restructuring charges as other current liabilities on the Consolidated Balance Sheets. The reserve balance at March 31, 2026 is expected to be used in the next twelve months.

Balance at December 31, 2025		$	2.6
Expenses			—
Payments			(1.3	)
Balance at March 31, 2026		$	1.3

Note 7 – Other (Income) Expense, net

The following table provides the components of other (income) expense, net for the three months ended March 31, 2026 and 2025:

		Three Months Ended March 31,
		2026				2025
Pension and postretirement non-service benefit (income) loss		$	(2.2	)		$	(1.4	)

Sales and use tax refund			—				(0.8	)
Miscellaneous (income) expense			(0.2	)			(0.1	)
Total other (income) expense, net		$	(4.9	)		$	(2.3	)

Non-service related pension and other postretirement benefit income, for all years, consists primarily of the interest cost, expected return on plan assets and amortization components of net periodic cost.

For more details on the aforementioned remeasurement, refer to “Note 12 - Retirement and Postretirement Plans.”

Note 8 - Income Tax Provision

Metallus’ provision for income taxes in interim periods is computed by applying the appropriate estimated annual effective tax rates to income or loss before income taxes for the period. In addition, non-recurring or discrete items, including interest on prior-year tax liabilities, are recorded during the periods in which they occur.

		Three Months Ended March 31,
		2026				2025
Provision (benefit) for incomes taxes		$	2.6			$	1.6
Effective tax rate			32.5	%			53.3	%

Income tax expense for the three months ended March 31, 2026 was calculated using forecasted multi-jurisdictional annual effective tax rates to determine a blended annual effective tax rate. The effective tax rate for the three months ended March 31, 2026 was 32.5% compared to 53.3% in the three months ended March 31, 2025. The decrease in the effective tax rate for the three months ended March 31, 2026 is primarily related to higher pre-tax income and the impact of discrete items related to stock based compensation awards.

10

Table of Contents

For the three months ended March 31, 2026 and 2025, there were $1.8 million of state and local income tax refunds. For the three months ended March 31, 2026, there were no tax payments. In April 2026, the Company received a $2.2 million refund from the Internal Revenue Service (“IRS”) for overpayments of 2024 federal estimated taxes.

Note 9 - Earnings (Loss) Per Share

Basic earnings (loss) per share is computed based upon the weighted average number of common shares outstanding. Diluted earnings (loss) per share is computed based upon the weighted average number of common shares outstanding plus the dilutive effect of common share equivalents calculated using the treasury stock method or if-converted method. For the Convertible Notes, the Company utilizes the if-converted method to calculate diluted earnings (loss) per share. Under the if-converted method, the Company adjusts net earnings to add back interest expense (including amortization of debt issuance costs) recognized on the Convertible Notes and includes the number of shares potentially issuable related to the Convertible Notes in the weighted average shares outstanding. Treasury shares are excluded from the denominator in calculating both basic and diluted earnings (loss) per share.

Equity-based Awards

Common share equivalents for shares issuable for equity-based awards amounted to 2.7 million shares for the three months ended March 31, 2026. For the three months ended March 31, 2026, 0.2 million shares were excluded from the computation of diluted earnings (loss) per share, primarily related to options with exercise prices above the average market price of our common shares (i.e., “underwater” options), because the effect of their inclusion would have been anti-dilutive. The difference between the remaining 2.5 million shares and 1.0 million shares assumed purchased with potential proceeds for the three months ended March 31, 2026, were included in the denominator of the diluted earnings (loss) per share calculation.

Common share equivalents for shares issuable for equity-based awards amounted to 2.4 million shares for the three months ended March 31, 2025. For the three months ended March 31, 2025, 0.4 million shares were excluded from the computation of diluted earnings (loss) per share, primarily related to options with exercise prices above the average market price of our common shares (i.e., “underwater” options), because the effect of their inclusion would have been anti-dilutive. The difference between the remaining 2.0 million shares and 1.1 million shares assumed purchased with potential proceeds for the three months ended March 31, 2025, were included in the denominator of the diluted earnings (loss) per share calculation.

Table of Contents

Convertible Notes

Common share equivalents for shares issuable upon the conversion of outstanding Convertible Notes were excluded in the computation of diluted earnings (loss) per share for three months ended March 31, 2025 as these shares would be anti-dilutive. There is no dilution on the Convertible Notes in 2026 as these were settled during the second quarter of 2025.

The following table sets forth the reconciliation of the numerator and the denominator of basic and diluted earnings (loss) per share for the three months ended March 31, 2026 and 2025:

Note 11 - Financing Arrangements

For a detailed discussion of the Company's long-term debt and credit arrangements, refer to “Note 12 - Financing Arrangements” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. The Company has no outstanding debt as of March 31, 2026.

Credit Agreement

On September 30, 2022, the Company, as borrower, and certain domestic subsidiaries of the Company, as subsidiary guarantors (the “Subsidiary Guarantors”), entered into a Fourth Amended and Restated Credit Agreement (the “Amended Credit Agreement”), with JPMorgan Chase Bank, N.A., as administrative agent (the “Administrative Agent”), and the lenders party thereto (collectively, the “Lenders”), which further amended and restated the Company’s existing secured Third Amended and Restated Credit Agreement, dated as of October 15, 2019.

As of March 31, 2026, the amount available under the Amended Credit Agreement was $270.7 million, reflective of the Company’s asset borrowing base with no outstanding borrowings. Additionally, the Company is in compliance with all covenants outlined in the Amended Credit Agreement.

Interest (Income) Expense, net

The following table provides the components of interest (income) expense, net for the three months ended March 31, 2026 and 2025:

		Three Months Ended March 31,
		2026				2025
Interest expense		$	0.4			$	0.5
Interest income			(0.8	)			(2.0	)
Interest (income) expense, net		$	(0.4	)		$	(1.5	)

Interest expense for the three months ended March 31, 2026 is primarily driven by capital lease obligations. Interest income primarily relates to interest earned on cash invested in a money market fund and deposits with financial institutions. As of March 31, 2026, the carrying value of the Company's money market investment was $12.6 million, which approximates the fair value. The Company had $42.6 million in cash invested in a money market fund as of March 31, 2025. The money market fund is a cash equivalent and is included in cash and cash equivalents on the Consolidated Balance Sheets. The fund consists of highly liquid investments with an average maturity of three months or less and falls within Level 1 of the fair value hierarchy as defined by applicable accounting guidance. Additionally, as of March 31, 2026 and 2025, the Company had $59.6 and $126.9 million, respectively, of cash held in other accounts which generate interest income at a rate similar to the money market fund.

Treasury Shares

On December 20, 2021, Metallus announced that its Board of Directors authorized a share repurchase program under which the Company may repurchase up to $50.0 million of its outstanding common shares. On November 2, 2022, the Board of Directors authorized an additional $75.0 million towards its share repurchase program and on May 6, 2024 the Board of Directors authorized an additional $100.0 million. The share repurchase program is intended to return capital to shareholders while also offsetting dilution from annual equity compensation awards. The share repurchase program does not require the Company to acquire any dollar amount or number of shares and may be modified, suspended, extended or terminated by the Company at any time without prior notice. These authorizations reflect the continued confidence of the Board and senior leadership in the Company’s ability to generate sustainable through-cycle profitability while maintaining a strong balance sheet and cash flow.

For the three months ended March 31, 2026, the Company repurchased approximately 0.3 million common shares in the open market at an aggregate cost of $4.3 million, which equates to an average repurchase price of $15.55 per share. As of March 31, 2026, the Company had a balance of $85.4 million remaining on its authorized share repurchase program.

13

Table of Contents

For the three months ended March 31, 2025, the Company repurchased approximately 0.4 million common shares at an aggregate cost of $5.6 million in the open market, which equates to an average repurchase price of $14.23 per share.

Note 12 - Retirement and Postretirement Plans

Plan Amendments and Updates

Bargaining Plan

On February 5, 2026, the United Steelworkers (“USW”) Local 1123 voted to ratify a new four-year contract (the “Contract”). The Contract, which is in effect until September 30, 2029, offers Metallus’ bargaining employees an increase to base wages every year, competitive healthcare and retirement benefits for all members, and has a continued focus on employee wellbeing as well as safe and sustainable operations. The Contract covers approximately 1,200 bargaining employees at the Company’s Canton, Ohio operations.

The Contract ratification resulted in several changes to the Bargaining Plan, including the option for eligible employees to freeze their pension accrual in exchange for an opportunity to elect an in-service lump sum distribution of their pension benefit at age 59 1/2. These changes required a remeasurement of the Bargaining Plan's pension obligations and plan assets during the first quarter of 2026. A gain of $2.5 million was recognized for the three months ended March 31, 2026, primarily driven by investment gains on plan assets and a decrease in the net pension liability as a result of an increase in the discount rate.

The remeasurement incorporated various assumptions used by the Company’s actuaries in calculating pension obligations and plan assets. These assumptions include discount rates, the expected return on plan assets, and estimates of the number of eligible employees expected to elect an in‑service lump‑sum distribution. Actual results differing from these assumptions, as well as changes in assumptions, could affect future pension expense and obligations.

In the three months ended March 31, 2026, the Company contributed a total of $19.8 million to its pension plans. In April 2026, the Company contributed an additional $5.4 million to the Bargaining Plan and anticipates additional pension contributions of approximately $5.0 million for the remainder of 2026. Required future pension contribution timing and amounts are subject to significant change based on future investment performance, Company estimates and actuarial assumptions, as well as current funding laws.

Salaried Plan

During the fourth quarter of 2021, the Company's Board of Directors approved the termination of the Salaried Plan and the plan was terminated effective March 31, 2022, subject to regulatory approval which was received in the fourth quarter of 2023. On May 15, 2024, the Company entered into an agreement to purchase a group annuity contract from The Prudential Insurance Company of America ("Prudential") in connection with the annuitization of the Salaried Plan. Following the completion of the annuity contract, there were surplus assets which were used to make a one-time 401(k) contribution to eligible employees. As a result, the Company recognized a loss of $3.6 million in the first quarter of 2025 when the remaining assets were distributed.

		Pension
		United States of America								Foreign
		Bargaining Plan				Supplemental Plan				Pension Plans				Total Pension				Postretirement Plans
Service cost		$	2.2			$	—			$	—			$	2.2			$	0.1

Net Periodic Benefit Cost (Income)		$	1.5			$	0.2			$	0.1			$	1.8			$	(1.0	)

The Bargaining Plan and Supplemental Plan each have a provision that permits employees to elect to receive their pension benefits in a lump sum upon retirement. The Company's accounting policy is to recognize settlements during the quarter in which it is projected that the costs of all settlements during the year will be greater than the sum of the service cost and interest cost components.

Note 13 – Stock-Based Compensation

During the three months ended March 31, 2026, the Board of Directors granted 378,000 time-based restricted stock units and 308,000 performance-based restricted stock units, which primarily relates to the annual grant to our employees. During the three months ended March 31, 2025, the Board of Directors granted 470,980 time-based restricted stock units and 329,580 performance-based restricted stock units, which relates to the annual grant to our employees.

Time-based restricted stock units are issued with the fair value equal to the closing market price of Metallus common shares on the date of grant. These restricted stock units do not have any performance conditions for vesting. Expense is recognized over the service period, adjusted for any forfeitures that occur during the vesting period. The weighted average fair value of the restricted stock units granted during the three months ended March 31, 2026 was $17.72 per share.

Performance-based restricted stock units issued in 2026 vest based on achievement of a total shareholder return (“TSR”) metric. The TSR metric is considered a market condition, which requires Metallus to reflect it in the fair value on grant date using an advanced option-pricing model. The fair value of each performance share was therefore determined using a Monte Carlo valuation model, a generally accepted lattice pricing model under ASC 718 – Stock-based Compensation. The Monte Carlo valuation model,

15

Table of Contents

among other factors, uses commonly-accepted economic theory underlying all valuation models, estimates fair value using simulations of future share prices based on stock price behavior and considers the correlation of peer company returns in determining fair value. The fair value of the performance-based restricted stock units granted during the three months ended March 31, 2026 was $17.21 per share.

Metallus recognized stock-based compensation expense of $3.3 million for the three months ended March 31, 2026 compared to $3.4 million for the three months ended March 31, 2025. Future stock-based compensation expense related to the unvested portion of all awards is approximately $26.0 million. The future expense is expected to be recognized over the remaining vesting periods through 2029.

Note 14 - Accumulated Other Comprehensive Income (Loss)

Changes in accumulated other comprehensive income (loss) for the three months ended March 31, 2026 and 2025 by component were as follows:

Note 15 – Contingencies

Metallus has a number of loss exposures incurred in the ordinary course of business, such as environmental claims, product warranty claims, employee-related matters, and other litigation. Establishing loss reserves for these matters requires

management’s estimate and judgment regarding risk exposure and ultimate liability or realization. These loss reserves are reviewed periodically and adjustments are made to reflect the most recent facts and circumstances. Accruals related to environmental claims represent management’s best estimate of the fees and costs associated with these claims. Although it is not possible to predict with certainty the outcome of such claims, management believes that their ultimate dispositions should not have a material adverse effect on our financial position, cash flows or results of operations.

Overview

Business Overview

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. Our products and solutions are used in a diverse range of demanding applications in the following end-markets: industrial, automotive, aerospace & defense, and energy.

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.

Business Highlights

The following items represent key trends and events during the three months ended March 31, 2026:

•Capital investments: The Company continues to invest organically with capital investments of $24.7 million in the three months ended March 31, 2026. Investments included targeted spending for improved safety, equipment automation, and continuous improvement to drive best-in-class quality and asset reliability, as well as new assets to increase throughput and efficiency which are being substantially funded by the U.S. government.

•Government Funding: In the three months ended March 31, 2026, the Company received $4.9 million from the U.S. government as part of the previously announced $99.75 million funding agreement 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. The Company expects the remaining funding to be provided as mutually agreed upon milestones are achieved throughout the project. The Company plans to commission and ramp-up production of the new bloom reheat furnace and roller furnace during 2026. Through March 31, 2026, and inclusive of amounts received in 2024 and 2025, the Company has received $91.5 million of government funding, with total spend of $108.1 million.

•Liquidity: Our balance sheet has remained strong, with total liquidity of $374.7 million, including cash and cash equivalents of $104.0 million as of March 31, 2026. Operating cash outflow of $26.9 million in the first quarter was primarily due to higher working capital requirements to support ramping business needs and the timing of required pension contributions, as expected.

•Share repurchase program: The Company repurchased 0.3 million common shares in the open market at an aggregate cost of $4.3 million in the three months ended March 31, 2026. As of March 31, 2026, the Company had a balance of $85.4 million remaining on its authorized share repurchase program.

•United Steelworkers ("USW") contract: The USW Local 1123 ratified a new four-year labor agreement with Metallus on February 5, 2026. A one‑time payment in the total amount of $1.9 million was made in the first quarter of 2026 to union employees, in accordance with the terms of the agreement, along with $0.3 million of one-time payments related to external parties assisting with achieving the new labor agreement.

Results of Operations

Net Sales

The charts below present net sales and shipments for the three months ended March 31, 2026 and 2025.

Net sales for the three months ended March 31, 2026 were $308.3 million, an increase of $27.8 million, or 9.9% compared with the three months ended March 31, 2025. The increase in net sales was primarily driven by higher shipments and surcharges as a result of higher scrap and alloy market prices. Higher volume of 10.9 thousand ship tons resulted in a net sales increase of $16.1 million across all end-markets except energy. The increase in surcharges of $11.7 million was primarily a result of higher shipments, scrap and alloy prices and energy surcharges. Excluding surcharges, net sales increased $16.1 million or 7.2%.

Gross Profit

The chart below presents the drivers of the gross profit variance from the three months ended March 31, 2025 as compared to the three months ended March 31, 2026.

Gross profit for the three months ended March 31, 2026 increased $3.2 million, or 14.6% compared with the three months ended March 31, 2025. The increase was primarily driven by higher volume, favorable price/mix and raw material spread, partially offset by higher manufacturing costs. All end-market sectors except energy were favorably impacted by higher volume. Favorable price/mix was due to higher aerospace & defense shipments, partially offset by higher automotive shipments. Raw material spread increased due to higher shipments and alloy prices. Unfavorable manufacturing was due to higher utility costs, increased costs related to the ratified union contract, and costs related to investments in our manufacturing optimization projects, partially offset by increased fixed cost leverage on higher production volume.

Selling, General and Administrative Expenses

The charts below present selling, general and administrative (“SG&A”) expense for the three months ended March 31, 2026 and 2025.

SG&A expense for the three months ended March 31, 2026 decreased by $2.1 million, or 8.6%, compared with the same period in 2025. The decrease was primarily due to lower professional services and salary and benefits expense.

Interest (Income) Expense, net

Net interest income for the three months ended March 31, 2026 was $0.4 million compared with net interest income of $1.5 million for the three months ended March 31, 2025. The decline in net interest income was primarily due to a combination of lower interest rates and average cash balances in 2026 compared to 2025. Refer to “Note 11 - Financing Arrangements” in the Notes to the unaudited Consolidated Financial Statements for additional information.

Non-GAAP Financial Measures

Net Sales, Excluding Surcharges

The tables below present net sales by end-markets, adjusted to exclude surcharges, which represents a financial measure that has not been determined in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). We believe presenting net sales by end-markets, both on a gross basis and on a per ton basis, adjusted to exclude raw material and energy surcharges, provides additional insight into key drivers of net sales such as base price and product mix. Due to the fact that the surcharge mechanism can introduce volatility to our net sales, net sales adjusted to exclude surcharges provides management and investors clarity of our core pricing and results. Presenting net sales by end-markets, adjusted to exclude surcharges including on a per ton basis, allows management and investors to better analyze key market indicators and trends and allows for enhanced comparison between our end-markets.

When surcharges are included in a customer agreement and are applicable (i.e., reach the threshold amount), based on the terms outlined in the respective agreement, surcharges are then included as separate line items on a customer’s invoice. These additional surcharge line items adjust base prices to match cost fluctuations due to market conditions. Each month, the Company will post on the surcharges page of its external website, as well as our customer portal, the scrap, alloy, and energy surcharges that will be applied (as a separate line item) to invoices dated in the following month (based upon shipment volumes in the following month). All surcharges invoiced are included in GAAP net sales.

Liquidity and Capital Resources

Credit Agreement

On September 30, 2022, the Company, as borrower, and certain domestic subsidiaries of the Company, as subsidiary guarantors, entered into a Fourth Amended and Restated Credit Agreement (the “Amended Credit Agreement”), with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto, which further amended and restated the Company’s secured Third Amended and Restated Credit Agreement, dated as of October 15, 2019.

Refer to “Note 11 - Financing Arrangements” in the Notes to the unaudited Consolidated Financial Statements for additional information.

Additional Liquidity Considerations

The following represents a summary of key liquidity measures under the Amended Credit Agreement as of March 31, 2026 and December 31, 2025:

		March 31, 2026				December 31, 2025
Cash and cash equivalents		$	104.0			$	156.7
Credit Agreement:
Maximum availability		$	400.0			$	400.0

Letter of credit obligations			(5.3	)			(5.3	)
Availability not borrowed		$	270.7			$	232.5
Total liquidity		$	374.7			$	389.2

(1) As of March 31, 2026, and December 31, 2025, Metallus had less than $400.0 million in collateral assets to borrow against.

Our principal sources of liquidity are cash and cash equivalents, cash flows from operations and available borrowing capacity under our Credit Agreement. As of March 31, 2026, taking into account our view of industrial, automotive, aerospace & defense and energy market demand for our products, and our 2026 operating and long-range plan, we believe that our cash balance as of March 31, 2026, projected cash generated from operations, borrowings available under the Credit Agreement and committed government funding to support capital investments, will be sufficient to satisfy our working capital needs, capital expenditures and other liquidity requirements associated with our operations, including pension and postretirement benefit obligations, for at least the next twelve months. We expect capital expenditures to be approximately $70 million in 2026, inclusive of approximately $35 million of capital expenditures funded by the U.S. government.

To the extent our liquidity needs prove to be greater than expected or cash generated from operations is less than anticipated, and cash on hand or credit availability is insufficient, we would seek additional financing to provide additional liquidity. We regularly evaluate our potential access to the equity and debt capital markets as sources of liquidity and we believe additional financing would likely be available if necessary, although we can make no assurance as to the form or terms of any such financing.

We continue to evaluate the best use of our liquidity which would allow us to invest in profitable growth, maintain a strong balance sheet, and return capital to shareholders.

For the three months ended March 31, 2026, the Company repurchased approximately 0.3 million common shares at an aggregate cost of $4.3 million in the open market, which equates to an average repurchase price of $15.55 per share. As of March 31, 2026, the Company had a balance of $85.4 million remaining under its share repurchase program. The share repurchase program is

25

Table of Contents

intended to return capital to shareholders while also offsetting dilution from annual equity compensation awards. The share repurchase program does not require the Company to acquire any dollar amount or number of shares and may be modified, suspended, extended or terminated by the Company at any time without prior notice. These authorizations reflect the continued confidence of the Board and senior leadership in the Company’s ability to generate sustainable through-cycle profitability while maintaining a strong balance sheet and cash flow.

Cash Flows

The following table reflects the major categories of cash flows for the three months ended March 31, 2026 and 2025. For additional details, please refer to the unaudited Consolidated Statements of Cash Flows included in this quarterly report.

		Three Months Ended March 31,
		2026				2025
Net cash provided (used) by operating activities		$	(26.9	)		$	(38.9	)
Net cash provided (used) by investing activities			(18.8	)			(12.9	)
Net cash provided (used) by financing activities			(7.0	)			(8.2	)
Increase (Decrease) in Cash and Cash Equivalents		$	(52.7	)		$	(60.0	)

Operating activities

Net cash used by operating activities for the three months ended March 31, 2026 was $26.9 million compared to net cash used of $38.9 million for the three months ended March 31, 2025. The decrease in the first quarter seasonal cash flow usage year over year primarily relates to lower pension contributions in 2026.

Investing activities

Net cash used by investing activities for the three months ended March 31, 2026 was $18.8 million compared to net cash used of $12.9 million for the three months ended March 31, 2025. The change was due to lower proceeds from government funding in the three months ended March 31, 2026 compared to the same period in 2025.

Financing activities

Net cash used by financing activities for the three months ended March 31, 2026 was $7.0 million compared to net cash used of $8.2 million in the three months ended March 31, 2025. The change was primarily due to lower repurchases of common shares, partially offset by higher shares surrendered for taxes in 2026 compared to the same period in 2025.
