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.

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.

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 3 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.

26 EARNINGS The first corporate goal for Worthington Industries is to earn money for its shareholders and increase the value of their investment. We believe that the best measurement of the accomplishment of our goal is consistent growth in earnings per share. OUR GOLDEN RULE We treat our customers, employees, investors and suppliers, as we would like to be treated. PEOPLE We are dedicated to the belief that people are our most important asset. We believe people respond to recognition, opportunity to grow and fair compensation. We believe that compensation should be directly related to job performance and therefore use incentives, profit sharing or otherwise, in every possible situation. From employees we expect an honest day's work for an honest day's pay We believe in the philosophy of continued employment for all Worthington people. In filling job openings, every effort is expended to find candidates within Worthington, its divisions or subsidiaries. CUSTOMERS Without the customer and their need for our products and services we have nothing. We will exert every effort to see that the customer’s quality and service requirements are met. Once a commitment is made to a customer, every effort is made to fulfill that obligation. SUPPLIERS We cannot operate profitably without those who supply the quality materials we need. We ask that suppliers be competitive in the marketplace with regard to quality, pricing, delivery and volume purchased. We are a loyal customer to suppliers who meet our quality and service requirements through all market conditions. ORGANIZATION We believe in a divisionalized organizational structure with responsibility for performance resting with the head of each operation. All managers are given the operating latitude and authority to accomplish their responsibilities within our corporate goals and objectives. In keeping with this philosophy, we do not create excessive corporate procedures. If procedures are necessary within a particular company operation, that manager creates them. We believe in a small corporate staff and support group to service the needs of our shareholders and operating units as requested. COMMUNICATION We communicate through every possible channel with our customers, employees, shareholders, suppliers and financial community. CITIZENSHIP Worthington Steel practices good citizenship at all levels. We conduct our business in a professional and ethical manner.

Worthington Industries Reconciliation of Non-GAAP Measures(in thousands) Below provides a reconciliation of trailing twelve months adjusted EBITDA as of August 31, 2023 and 2022 for Worthington Industries, Inc. along with the calculation of net debt to adjusted EBITDA for the same periods. The calculation of adjusted EBITDA for Worthington Industries, Inc. is consistent with the definition previously provided, except that no adjustment is made for stock-based compensation. Net debt to adjusted EBITDA is calculated by subtracting cash from net debt (defined as the aggregate of short-term borrowings, current maturities of long-term debt and long-term debt) and dividing the sum by adjusted EBITDA for the trailing twelve months. 31
