FORWARD-LOOKING STATEMENTS Certain statements made in this presentation may constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements involve risks and uncertainties. The words “anticipate,” “believe,” “expect,” “intend,” “may,” “project,” “will,” “should,” “could” and similar expressions are intended to identify forward-looking statements. These forward-looking statements reflect the Company’s best judgment based on current information, and although we base these statements on circumstances that we believe to be reasonable when made, there can be no assurance that future events will not affect the accuracy of such forward-looking information. The Company does not undertake any obligation to update these statements. The forward-looking statements are not guarantees of future performance, and actual results may vary materially from the projected results and expectations discussed in this presentation. Factors that might cause the Company’s actual results to differ materially from those anticipated in forward- looking statements include, but are not limited to: (1) competitive pressure on sales and pricing, including pressure from imports and substitute materials; (2) U.S. and foreign trade policies affecting steel imports or exports; (3) the sensitivity of the results of our operations to general market conditions, and in particular, prevailing market steel prices and changes in the supply and cost of raw materials, including pig iron, iron ore and scrap steel; (4) the availability and cost of electricity and natural gas, which could negatively affect our cost of steel production or result in a delay or cancellation of existing or future drilling within our natural gas drilling programs; (5) critical equipment failures and business interruptions; (6) market demand for steel products, which, in the case of many of our products, is driven by the level of nonresidential construction activity in the United States; (7) impairment in the recorded value of inventory, equity investments, fixed assets, goodwill or other long- lived assets; (8) uncertainties and volatility surrounding the global economy, including excess world capacity for steel production, inflation and interest rate changes; (9) fluctuations in currency conversion rates; (10) significant changes in laws or government regulations affecting environmental compliance, including legislation and regulations that result in greater regulation of greenhouse gas emissions that could increase our energy costs, capital expenditures and operating costs or cause one or more of our permits to be revoked or make it more difficult to obtain permit modifications; (11) the cyclical nature of the steel industry; (12) capital investments and their impact on our performance; (13) our safety performance; (14) our ability to integrate businesses we acquire; (15) the impact of any pandemic or public health situation; and (16) the risks discussed in “Item 1A. Risk Factors” of the Company’s most recent Annual Report on Form 10-K and elsewhere therein and in the other reports we file with the U.S. Securities and Exchange Commission. 2

NON-GAAP FINANCIAL MEASURES The Company uses certain non-GAAP (Generally Accepted Accounting Principles) financial measures in this presentation, including adjusted earnings, EBITDA and Free Cash Flow (FCF). Generally, a non-GAAP financial measure is a numerical measure of a company’s performance or financial position that either excludes or includes amounts that are not normally excluded or included in the most directly comparable financial measure calculated and presented in accordance with GAAP. We define EBITDA as net earnings before noncontrolling interests adding back the following items: interest expense, net; provision for income taxes; depreciation; amortization; and losses and impairments of assets. We define Free Cash Flow (FCF) as Cash Provided by Operating Activities less Capital Expenditures. Please note that other companies might define their non-GAAP financial measures differently than we do. Management presents non-GAAP financial measures because it considers them to be an important supplemental measure of performance. Management believes that these non-GAAP financial measures provide additional insight for analysts and investors evaluating the Company’s financial and operational performance by providing a consistent basis of comparison across periods. Non-GAAP financial measures have limitations as an analytical tool. Investors are encouraged to review the reconciliation of non-GAAP financial measures to their most directly comparable GAAP financial measures provided in this presentation, including in the accompanying tables located in the Appendix. 3
