Notes to Investors FORWARD LOOKING STATEMENTS. Worthington Industries, Inc. (“Worthington”) and Worthington Steel, Inc. (“Worthington Steel” or the “Company) wish to take advantage of the Safe Harbor provisions included in the Private Securities Litigation Reform Act of 1995 (the “Act”). Statements by Worthington and/or the Company relating to the intended separation of Worthington’s Steel Processing business; the timing and method of the separation; the anticipated benefits of the separation; the expected financial and operating performance of, and future opportunities for, each company following the separation; the tax treatment of the transaction; the leadership of each company following the separation; and other non- historical matters constitute “forward-looking statements” within the meaning of the Act. Forward-looking statements may be characterized by terms such as “believe,” “anticipate,” “should,” “would,” “intend,” “plan,” “will,” “expect,” “estimate,” “project,” “positioned,” “strategy,” “targets,” “aims,” “seeks,” “sees” and similar expressions. Because they are based on beliefs, estimates and assumptions, forward-looking statements are inherently subject to risks and uncertainties that could cause actual results to differ materially from those projected. Any number of factors could affect actual results, including, without limitation, the final approval of the separation by our board of directors; the uncertainty of obtaining regulatory approvals in connection with the separation; the ability to satisfy the necessary closing conditions to complete the separation on a timely basis, or at all; our ability to successfully separate the two companies and realize the anticipated benefits of the separation; the risks, uncertainties and impacts, for both Worthington and/or the Company’s business and the planned separation, related to the United Auto Workers strikes against Ford, General Motors and Stellantis North America (the “Detroit Three automakers”), and the associated impact on companies that supply the Detroit Three automakers, the duration and scope of which are impossible to predict; the effect of conditions in national and worldwide financial markets, including inflation, increases in interest rates and economic recession, and with respect to the ability of financial institutions to provide capital; the impact of tariffs, the adoption of trade restrictions affecting Worthington and/or the Company products or suppliers, a United States withdrawal from or significant renegotiation of trade agreements, the occurrence of trade wars, the closing of border crossings, and other changes in trade regulations or relationships; changing oil prices and/or supply; product demand and pricing; changes in product mix, product substitution and market acceptance of Worthington and/or the Company’s products; volatility or fluctuations in the pricing, quality or availability of raw materials (particularly steel), supplies, transportation, utilities, labor and other items required by operations (especially in light of Russia’s invasion of Ukraine); effects of sourcing and supply chain constraints; the outcome of adverse claims experience with respect to workers’ compensation, product recalls or product liability, casualty events or other matters; effects of facility closures and the consolidation of operations; the effect of financial difficulties, consolidation and other changes within the steel, automotive, construction and other industries in which Worthington and/or the Company participates; failure to maintain appropriate levels of inventories; financial difficulties (including bankruptcy filings) of original equipment manufacturers, end-users and customers, suppliers, joint venture partners and others with whom Worthington and/or the Company does business; the ability to realize targeted expense reductions from headcount reductions, facility closures and other cost reduction efforts; the ability to realize cost savings and operational, sales and sourcing improvements and efficiencies, and other expected benefits from transformation initiatives, on a timely basis; the overall success of, and the ability to integrate, newly- acquired businesses and joint ventures, maintain and develop their customers, and achieve synergies and other expected benefits and cost savings therefrom; capacity levels and efficiencies, within facilities, within major product markets and within the industries in which Worthington and/or the Company participates as a whole; the effect of disruption in the business of suppliers, customers, facilities and shipping operations due to adverse weather, casualty events, equipment breakdowns, labor shortages, interruption in utility services, civil unrest, international conflicts (especially in light of Russia’s invasion of Ukraine), terrorist activities or other causes; changes in customer demand, inventories, spending patterns, product choices, and supplier choices; risks associated with doing business internationally, including economic, political and social instability (especially in light of Russia’s invasion of Ukraine), foreign currency exchange rate exposure and the acceptance of Worthington and/or the Company’s products in global markets; the ability to improve and maintain processes and business practices to keep pace with the economic, competitive and technological environment; the effect of inflation, interest rate increases and economic recession, as well as potential adverse impacts as a result of the Inflation Reduction Act of 2022, which may negatively impact Worthington and/or the Company’s operations and financial results; deviation of actual results from estimates and/or assumptions used by Worthington and/or the Company in the application of its significant accounting policies; the level of imports and import prices in Worthington and/or the Company’s markets; 1

Notes to Investors the impact of environmental laws and regulations or the actions of the United States Environmental Protection Agency or similar regulators which increase costs or limit Worthington and/or the Company’s ability to use or sell certain products; the impact of increasing environmental, greenhouse gas emission and sustainability considerations or regulations; the impact of judicial rulings and governmental regulations, both in the United States and abroad, including those adopted by the United States Securities and Exchange Commission (“SEC”) and other governmental agencies as contemplated by the Coronavirus Aid, Relief and Economic Security (CARES) Act, the Consolidated Appropriations Act, 2021, the American Rescue Act of 2021, and the Dodd-Frank Wall Street Reform and the Consumer Protection Act of 2010; the effect of healthcare laws in the United States and potential changes for such laws, especially in light of the COVID-19 pandemic which may increase Worthington and/or the Company’s healthcare and other costs and negatively impact Worthington and/or the Company’s operations and financial results; the effect of tax laws in the U.S. and potential changes for such laws, which may increase Worthington and/or the Company's costs and negatively impact its operations and financial results; cyber security risks; the effects of privacy and information security laws and standards; and other risks described from time to time in the filings of Worthington Industries, Inc. with the SEC, including those described in “Part I — Item 1A. — Risk Factors” of Worthington’s Annual Report on Form 10-K for the fiscal year ended May 31, 2023, and its subsequent filings with the SEC, and in the Registration Statement on Form 10 filed by Worthington Steel (the Form 10 ), including those described in Risk Factors , as may be further amended. Forward-looking statements should be construed in the light of such risks. Readers are cautioned not to place undue reliance on any forward-looking statements, which speak only as of the date made. Worthington and/or Company does not undertake, and hereby disclaim, any obligation to update any forward-looking statements, whether as a result of new information, future developments or otherwise. Market, Industry and Other Data: Unless otherwise indicated, information in this presentation concerning our industry, the industries we serve and the markets in which we operate, including our general expectations, market position, market opportunity and market share, is based on information from third-party sources and management estimates. Management estimates are derived from publicly available information and reports provided to us (including reports from S&P Global Mobility and other industry publications, surveys and forecasts), our knowledge of our industry and assumptions based on such information and knowledge, which we believe to be reasonable. Management estimates have not been verified by any independent source. S&P reports, data and information referenced herein (the “S&P Materials”) are the copyrighted property of S&P Global Inc. and its subsidiaries (“S&P”). The S&P Materials are from sources considered reliable; however, the accuracy and completeness thereof are not warranted, nor are the opinions and analyses published by S&P representations of fact. The S&P Materials speak as of the original publication date thereof and are subject to change without notice. S&P and other trademarks appearing in this S&P Materials are the property of S&P or their respective owners. FINANCIAL INFORMATION. Unless otherwise specified, all financial data and operating metrics included in these materials are presented on a carve-out basis, as presented in the Form 10 of Worthington Steel, Inc., as filed with the Securities and Exchange Commission. The financial information included in this document may not necessarily reflect Worthington Steel’s financial position, results of operations and cash flows in the future, or what Worthington Steel’s financial position, results of operations and cash flows would have been had Worthington Steel been a standalone, independent, publicly-traded company during the periods presented. 2

Notes to Investors NON-GAAP MEASURES. These materials present certain financial measures that are not calculated in accordance with U.S. generally accepted accounting principles, or GAAP. Management believes these non-GAAP measures provide useful supplemental information on the performance of the Company’s ongoing operations and should not be considered as an alternative to the comparable GAAP measure. Additionally, management believes these non-GAAP measures allow for meaningful comparisons and analysis of trends in Worthington and/or the Company’s businesses and enables investors to evaluate operations and future prospects in the same manner as management. A reconciliation of each non-GAAP measure to its most directly comparable GAAP measure is included in the Appendix. The following provides an explanation of each non-GAAP measure presented in these materials: Adjusted EBITDA is defined as Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization, and consists of EBITDA (calculated by adding or subtracting, as appropriate, interest expense, income tax expense and depreciation and amortization to/from net earnings attributable to controlling interest), which is further adjusted to exclude impairment and restructuring charges (gains) as well as other items that management believes are not reflective of, and thus should not be included when evaluating the performance of its ongoing operations, including incremental costs associated with the planned separation. Impairment charges are excluded from adjusted EBITDA because they do not occur in the ordinary course of our ongoing business operations, are inherently unpredictable in timing and amount, and are non-cash, which we believe facilitates the comparison of historical, current and forecasted financial results Restructuring activities, which can result in both discrete gains and/or losses, consist of established programs that are not part of our ongoing operations, such as divestitures, closing or consolidating facilities, employee severance (including rationalizing headcount or other significant changes in personnel), and realignment of existing operations (including changes to management structure in response to underlying performance and/or changing market conditions). Adjusted EBITDA Margin is calculated by dividing Adjusted EBITDA by net sales. Free Cash Flow is defined as operating cash flows less capital expenditures. This communication shall not constitute an offer of any securities for sale, nor shall there be any offer, sale or distribution of securities in any jurisdiction in which such offer, sale or distribution would be unlawful prior to appropriate registration or qualification under the securities laws of such jurisdiction. For additional information with respect to Worthington Steel and the separation, please refer to the Form 10. The consummation of the separation is subject to customary conditions, as further described in the Form 10. 3

Notes to Investors FORWARD LOOKING STATEMENTS. Worthington Industries, Inc. (the “Company” or “Worthington”) wishes to take advantage of the Safe Harbor provisions included in the Private Securities Litigation Reform Act of 1995 (the “Act”). Statements by the Company relating to the intended separation of Worthington’s Steel Processing business; the timing and method of the separation; the anticipated benefits of the separation; the expected financial and operating performance of, and future opportunities for, each company following the separation; the tax treatment of the transaction; the leadership of each company following the separation; and other non-historical matters constitute “forward-looking statements” within the meaning of the Act. Forward-looking statements may be characterized by terms such as “believe,” “anticipate,” “should,” “would,” “intend,” “plan,” “will,” “expect,” “estimate,” “project,” “positioned,” “strategy,” “targets,” “aims,” “seeks,” “sees” and similar expressions. Because they are based on beliefs, estimates and assumptions, forward-looking statements are inherently subject to risks and uncertainties that could cause actual results to differ materially from those projected. Any number of factors could affect actual results, including, without limitation, the final approval of the separation by our board of directors; the uncertainty of obtaining regulatory approvals in connection with the separation; the ability to satisfy the necessary closing conditions to complete the separation on a timely basis, or at all; our ability to successfully separate the two companies and realize the anticipated benefits of the separation; the risks, uncertainties and impacts, for both the Company’s business and the planned separation, related to the United Auto Workers strikes against Ford, General Motors and Stellantis North America (the “Detroit Three automakers”), and the associated impact on companies that supply the Detroit Three automakers, the duration and scope of which are impossible to predict; the effect of conditions in national and worldwide financial markets, including inflation, increases in interest rates and economic recession, and with respect to the ability of financial institutions to provide capital; the impact of tariffs, the adoption of trade restrictions affecting the Company’s products or suppliers, a United States withdrawal from or significant renegotiation of trade agreements, the occurrence of trade wars, the closing of border crossings, and other changes in trade regulations or relationships; changing oil prices and/or supply; product demand and pricing; changes in product mix, product substitution and market acceptance of the Company’s products; volatility or fluctuations in the pricing, quality or availability of raw materials (particularly steel), supplies, transportation, utilities, labor and other items required by operations (especially in light of Russia’s invasion of Ukraine); effects of sourcing and supply chain constraints; the outcome of adverse claims experience with respect to workers’ compensation, product recalls or product liability, casualty events or other matters; effects of facility closures and the consolidation of operations; the effect of financial difficulties, consolidation and other changes within the steel, automotive, construction and other industries in which the Company participates; failure to maintain appropriate levels of inventories; financial difficulties (including bankruptcy filings) of original equipment manufacturers, end-users and customers, suppliers, joint venture partners and others with whom the Company does business; the ability to realize targeted expense reductions from headcount reductions, facility closures and other cost reduction efforts; the ability to realize cost savings and operational, sales and sourcing improvements and efficiencies, and other expected benefits from transformation initiatives, on a timely basis; the overall success of, and the ability to integrate, newly-acquired businesses and joint ventures, maintain and develop their customers, and achieve synergies and other expected benefits and cost savings therefrom; capacity levels and efficiencies, within facilities, within major product markets and within the industries in which the Company participates as a whole; the effect of disruption in the business of suppliers, customers, facilities and shipping operations due to adverse weather, casualty events, equipment breakdowns, labor shortages, interruption in utility services, civil unrest, international conflicts (especially in light of Russia’s invasion of Ukraine), terrorist activities or other causes; changes in customer demand, inventories, spending patterns, product choices, and supplier choices; risks associated with doing business internationally, including economic, political and social instability (especially in light of Russia’s invasion of Ukraine), foreign currency exchange rate exposure and the acceptance of the Company’s products in global markets; the ability to improve and maintain processes and business practices to keep pace with the economic, competitive and technological environment; the effect of inflation, interest rate increases and economic recession, as well as potential adverse impacts as a result of the Inflation Reduction Act of 2022, which may negatively impact the Company’s operations and financial results; deviation of actual results from estimates and/or assumptions used by the Company in the application of its significant accounting policies; the level of imports and import prices in the Company’s markets; the impact of environmental laws and regulations or the actions of the United States Environmental Protection Agency or similar regulators which increase costs or limit the Company’s ability to use or sell certain products; the impact of increasing environmental, greenhouse gas emission and sustainability considerations or regulations; the impact of judicial rulings and governmental regulations, both in the United States and abroad, including those adopted by the United States Securities and Exchange Commission (“SEC”) and other governmental agencies as contemplated by the Coronavirus Aid, Relief and Economic Security (CARES) Act, the Consolidated Appropriations Act, 2021, the American Rescue Act of 2021, and the Dodd-Frank Wall Street Reform and the Consumer Protection Act of 2010; the effect of healthcare laws in the United States and potential changes for such laws, especially in light of the COVID-19 pandemic which may increase the Company’s healthcare and other costs and negatively impact the Company’s operations and financial results; the effect of tax laws in the U.S. and potential changes for such laws, which may increase the Company's costs and negatively impact its operations and financial results; cyber security risks; the effects of privacy and information security laws and standards; and other risks described from time to time in the filings of Worthington Industries, Inc. with the SEC, including those described in “Part I — Item 1A. — Risk Factors” of Worthington’s Annual Report on Form 10-K for the fiscal year ended May 31, 2023, and its subsequent filings with the SEC. Forward-looking statements should be construed in the light of such risks. Readers are cautioned not to place undue reliance on any forward-looking statements, which speak only as of the date made. Worthington does not undertake, and hereby disclaim, any obligation to update any forward-looking statements, whether as a result of new information, future developments or otherwise. 2

Notes to Investors PRO FORMA FINANCIAL INFORMATION. Unless otherwise specified, all financial data and operating metrics included in these materials are presented on a pro forma basis giving effect to the reorganization and the planned separation of the Steel Processing business, as described in the Form 10 filed with the Securities and Exchange Commission, and divested operations historically presented within Other. NON-GAAP MEASURES. These materials include certain financial measures that are not calculated in accordance with U.S. generally accepted accounting principles, or GAAP. Management believes these non-GAAP measures provide useful supplemental information on the performance of the Company’s ongoing operations and should not be considered as an alternative to the comparable GAAP measure. Additionally, management believes these non-GAAP measures allow for meaningful comparisons and analysis of trends in the Company’s businesses and enables investors to evaluate operations and future prospects in the same manner as management. A reconciliation of each non-GAAP measure to its most directly comparable GAAP measure is included in the Appendix. The following provides an explanation of each non-GAAP measure presented in these materials: Adjusted EBITDA is defined as Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization, and consists of EBITDA (calculated by adding or subtracting, as appropriate, interest expense, income tax expense and depreciation and amortization to/from net earnings attributable to controlling interest), which is further adjusted to exclude impairment and restructuring charges (gains) as well as other items that management believes are not reflective of, and thus should not be included when evaluating the performance of its ongoing operations, including incremental costs associated with the planned separation. Adjusted EBITDA also excludes stock-based compensation due to its non-cash nature. In prior periods, Adjusted EBITDA did not exclude stock-based compensation. However, management now believes that further excluding stock-based compensation from Adjusted EBITDA is useful to better understand the financial performance of our business and to facilitate a better comparison of our results to those of our peer companies over multiple periods given that this item may vary between companies for reasons unrelated to overall operating performance. Impairment charges are excluded from adjusted EBITDA because they do not occur in the ordinary course of our ongoing business operations, are inherently unpredictable in timing and amount, and are non- cash, which we believe facilitates the comparison of historical, current and forecasted financial results Restructuring activities, which can result in both discrete gains and/or losses, consist of established programs that are not part of our ongoing operations, such as divestitures, closing or consolidating facilities, employee severance (including rationalizing headcount or other significant changes in personnel), and realignment of existing operations (including changes to management structure in response to underlying performance and/or changing market conditions). Adjusted EBITDA Margin is calculated by dividing Adjusted EBITDA by net sales. Free Cash Flow is defined as Adjusted EBITDA less capital expenditures. Free Cash Flow Conversion is calculated by dividing Free Cash by Adjusted EBITDA. 3
