Forward-Looking StatementsCertain statements made in this presentation are forward-looking statements that involve

risks and uncertainties. The words “believe,” “expect,” “project,” “will,” “should,” “could” and similar expressions are intended to identify those 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. As such, 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 report. 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) the sensitivity of the results of our operations to prevailing steel prices and changes in the supply and cost of raw materials, including pig iron, iron ore and scrap steel; (2) availability and cost of electricity and natural gas which could negatively affect our cost of steel production or could result in a delay or cancellation of existing or future drilling within our natural gas working interest drilling programs; (3) critical equipment failures and business interruptions; (4) 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 U.S.; (5) competitive pressure on sales and pricing, including pressure from imports and substitute materials; (6) impairment in the recorded value of inventory, equity investments, fixed assets, goodwill or other long-lived assets; (7) uncertainties surrounding the global economy, including the severe economic downturn in construction markets and excess world capacity for steel production; (8) fluctuations in currency conversion rates; (9) U.S. and foreign trade policy affecting steel imports or exports; (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 and our 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; and (13) our safety performance.2
