Ryerson strongly urges you to review its filings with the Securities and Exchange Commission, which can be found at https://ir.ryerson.com/financials/sec-filings/default.aspx. This site also provides additional information about Ryerson. Safe Harbor Provision Certain statements made in this release and other written or oral statements made by or on behalf of the Company constitute “forward-looking statements” within the meaning of the federal securities laws, including statements regarding our future performance, as well as management's expectations, beliefs, intentions, plans, estimates, objectives, or projections relating to the future. Such statements can be identified by the use of forward-looking terminology such as “objectives,” “goals,” “preliminary,” “range,” “believes,” “expects,” “may,” “estimates,” “will,” “should,” “plans,” or “anticipates” or the negative thereof or other variations thereon or comparable terminology, or by discussions of strategy. The Company cautions that any such forward-looking statements are not guarantees of future performance and may involve significant risks and uncertainties, and that actual results may vary materially from those in the forward-looking statements as a result of various factors. Among the factors that significantly impact our business are: the cyclicality of our business; the highly competitive, volatile, and fragmented metals industry in which we operate; the impact of geopolitical events; fluctuating metal prices; our indebtedness and the covenants in instruments governing such indebtedness; the integration of acquired operations; regulatory and other operational risks associated with our operations located inside and outside of the United States; the influence of a single investor group over our policies and procedures; work stoppages; obligations under certain employee retirement benefit plans; currency fluctuations; and consolidation in the metals industry. Forward-looking statements should, therefore, be considered in light of various factors, including those set forth above and those set forth under “Risk Factors” in our most recent annual report on Form 10-K for the year ended December 31, 2025, and in our other filings with the Securities and Exchange Commission. Moreover, we caution against placing undue reliance on these statements, which speak only as of the date they were made. The Company does not undertake any obligation to publicly update or revise any forward-looking statements to reflect future events or circumstances, new information or otherwise.

They should not be considered a replacement for GAAP results. Non-GAAP financial measures appearing in these slides are identified in the footnotes.
