Important risk factors that may cause such a difference include (i) the completion of the proposed transaction on the anticipated terms and timing or at all, including obtaining shareholder and regulatory approvals and anticipated tax treatment, (ii) potential unforeseen liabilities, future capital expenditures, revenues, expenses, earnings, economic performance, indebtedness, financial condition, losses and future prospects, (iii) the ability of CLF to integrate its and AKS’s businesses successfully and to achieve anticipated synergies, (iv) business and management strategies for the management, expansion and growth of the combined company’s operations following the consummation of the proposed transaction, (v) potential litigation relating to the proposed transaction that could be instituted against AKS, CLF or their respective directors, (vi) the risk that disruptions from the proposed transaction will harm AKS’ or CLF’s business, including current plans and operations, (vii) the ability of AKS or CLF to retain and hire key personnel, (viii) potential adverse reactions or changes to business relationships resulting from the announcement or completion of the proposed transaction, (ix) uncertainty as to the long-term value of CLF’s common stock, (x) continued availability of capital and financing and rating agency actions, (xi) legislative, regulatory and economic developments and (xii) unpredictability and severity of catastrophic events, including acts of terrorism or outbreak of war or hostilities, as well as management’s response to any of the aforementioned factors. These risks, as well as other risks associated with the proposed transaction, will be more fully discussed in the joint proxy statement/prospectus that will be included in the registration statement on Form S-4 that will be filed with the SEC in connection with the proposed transaction. While the list of factors presented here is, and the list of factors to be presented in the registration statement on Form S-4 are, considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Other factors that may present significant additional obstacles to the realization of forward looking statements or which could have a material adverse effect on AKS’ or CLF’s respective consolidated financial condition, results of operations, credit rating or liquidity are contained in AKS’s and CLF’s respective periodic reports filed with the SEC, including the AKS 10-K and CLF 10-K. Neither AKS nor CLF assumes any obligation to publicly provide revisions or updates to any forward looking statements, whether as a result of new information, future developments or otherwise, should circumstances change, except as otherwise required by applicable law. 2
