Forward Looking Statements and Non-GAAP Financial Measures

Forward-Looking Statements

This presentation contains some predictive statements about future events, including statements related to conditions in domestic or global economies, conditions in steel and recycled metals market places, Steel Dynamics' production capacities, shipments, revenues, costs of purchased materials, future profitability and earnings, and the operation of new, existing or planned facilities. These statements, which we generally precede or accompany by such typical conditional words as "anticipate," "intend," "believe," "estimate," "plan," "seek," "project" or "expect," or by the words "may," "will," or "should," are intended to be made as "forward-looking," subject to many risks and uncertainties, within the safe harbor protections of the Private Securities Litigation Reform Act of 1995. These statements speak only as of this date and are based upon information and assumptions, which we consider reasonable as of this date, concerning our businesses and the environments in which they operate. Such predictive statements are not guarantees of future performance, and we undertake no duty to update or revise any such statements. Some factors that could cause such forward-looking statements to turn out differently than anticipated include: (1) the effects of uncertain economic conditions; (2) the effects of pandemics or other health issues, such as the recent novel coronavirus outbreak (COVID-19); (3) cyclical and changing industrial demand; (4) changes in conditions in any of the steel or scrap-consuming sectors of the economy which affect demand for our products, including the strength of the non-residential and residential construction, automotive, manufacturing, appliance, energy, and other steel-consuming industries; (5) fluctuations in the cost of key raw materials and supplies (including steel scrap, iron units, zinc, graphite electrodes, and energy costs) and our ability to pass on any cost increases; (6) the impact of domestic and foreign imports, including trade policy, restrictions, or agreements; (7) unanticipated difficulties in integrating or starting up new, acquired or planned businesses or assets; (8) risks and uncertainties involving product and/or technology development; and (9) occurrences of unexpected plant outages or equipment failures.

More specifically, we refer you to Steel Dynamics' more detailed explanation of these and other factors and risks that may cause such predictive statements to turn out differently than expected or anticipated, as set forth in our most recent Annual Report on Form 10-K under the headings Special Note Regarding Forward-Looking Statements and Risk Factors, in our quarterly reports on Form 10-Q or in other reports which we from time to time file with the Securities and Exchange Commission. These are available publicly on the SEC website, www.sec.gov, and on the Steel Dynamics website, www.steeldynamics.com: Investors: SEC Filings.

Note Regarding Non-GAAP Financial Measures

Steel Dynamics reports its financial results in accordance with U.S. generally accepted accounting principles (GAAP). Management believes that EBITDA, Adjusted EBITDA, Adjusted Operating Income, Free Cash Flow and Free Cash Flow Conversion, non-GAAP financial measures, provide additional meaningful information regarding Steel Dynamic's performance and financial strength. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, Steel Dynamics' reported results prepared in accordance with GAAP. In addition, because not all companies use identical calculations, EBITDA, Adjusted EBITDA, Adjusted Operating Income, Free Cash Flow and Free Cash Flow Conversion included in this presentation may not be comparable to similarly titled measures of other companies. The reconciliations of these non-GAAP measures to their most comparable GAAP measures are contained in the appendix at the end of this presentation.
