Cautionary Note Regarding Forward-Looking Statements

This Current Report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, each as amended, including, in particular, statements about our plans, strategies and prospects and estimates of industry growth for the fiscal quarter ending December 28, 2012 and beyond. These statements identify prospective information and include words such as “expects,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “projects” and similar expressions. These forward-looking statements are based on information available to the Company as of the date of this Current report and are based on management’s current views and assumptions. These forward-looking statements are conditioned upon and also involve a number of known and unknown risks, uncertainties, and other factors that could cause actual results, performance or events to differ materially from those anticipated by these forward-looking statements. Such risks, uncertainties, and other factors may be beyond the Company’s control and may pose a risk to our operating and financial condition. Such risks and uncertainties include, but are not limited to; the uncertainty in global economic conditions as consumers and businesses may defer purchases in response to tighter credit and financial news, the impact of the variable demand and the adverse pricing environment for disk drives, particularly in view of current business and economic conditions; dependence on the Company’s ability to successfully qualify, manufacture and sell its disk drive products in increasing volumes on a cost-effective basis and with acceptable quality, particularly the new disk drive products with lower cost structures; the impact of competitive product announcements; and possible excess industry supply with respect to particular disk drive products; the Company’s ability to achieve projected cost savings in connection with restructuring plans and the risk that we will incur significant incremental costs in connection with the implementation of our recently executed transaction with Samsung Electronics Co., Ltd or that we will not achieve the benefits expected from such transactions. Information concerning risks, uncertainties and other factors that could cause results to differ materially from those projected in the forward-looking statements is contained in the Company’s Annual Report on Form 10-K with the U.S. Securities and Exchange Commission on August 8, 2012 which statements are incorporated into this Current report by reference. These forward-looking statements should not be relied upon as representing the Company’s views as of any subsequent date and the Company undertakes no obligation to update forward-looking statements to reflect events or circumstances after the date they were made.
