LSI GROUP December 16, 2025 Overview of Planned Acquisition

Notes to Investors FORWARD-LOOKING STATEMENTS.  Selected statements in this presentation constitute “forward-looking statements,” as that term is used in the Private Securities Litigation Reform Act of 1995 (the “Act”).  Worthington Enterprises, Inc. (the “Company” or “Worthington”) wishes to take advantage of the safe harbor provisions included in the Act. Forward-looking statements reflect the Company’s current expectations, estimates or projections concerning future results or events. These statements are often identified by the use of forward-looking words or phrases such as “believe,” “expect,” “anticipate,” “may,” “could,” “should,” “would,” “intend,” “plan,” “will,” “likely,” “estimate,” “project,” “position,” “strategy,” “target,” “aim,” “seek,” “foresee” and similar words or phrases. These forward-looking statements include, without limitation, statements relating to: future or expected cash positions, liquidity and ability to access financial markets and capital; outlook, strategy or business plans;; future or expected performance, growth, demand, financial condition or other financial measures; pricing trends for raw materials and finished goods; additions to product lines and opportunities to participate in new markets; anticipated working capital needs, capital expenditures and asset sales; anticipated improvements and efficiencies in costs, operations, sales, inventory management, sourcing and the supply chain; the ability to make acquisitions, form joint ventures and consolidate operations and the projected timing, benefits and costs related thereto; expectations for the economy and markets; expectations for shareholder value; effects of pandemics and widespread health crises; and other non-historical matters. 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, those that follow: 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 U.S. 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; 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, 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, 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, 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 U.S. 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 regulations or considerations; the impact of judicial rulings and governmental regulations, both in the U.S. and abroad, including those adopted by the U.S. 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 Plan Act of 2021, and the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010; the effect of healthcare laws in the U.S. and potential changes for such laws, 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 Company’s filings with the SEC, including those described in “Part I — Item 1A. — Risk Factors” of the Company’s Annual Report on Form 10-K for the fiscal year ended May 31, 2025, and its subsequent filings with the SEC. Forward-looking statements should be construed in the light of such risks. It is impossible to predict or identify all potential risk factors.  Consequently, readers should not consider the foregoing list to be a complete set of all potential risks and uncertainties.  Readers are cautioned not to place undue reliance on any forward-looking statements, which speak only as of the date made, which was December 16, 2025. The Company does not undertake, and hereby disclaims, any obligation to update any forward-looking statements, whether as a result of new information, future developments or otherwise, except as required by applicable law.
