SAFE HARBOR Forward Looking Statements These presentations contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including statements concerning growth opportunities in the storage industry, including growth in units shipped, areal density and content stored, our expected financial results, our business model and financial goals and our capital allocation strategy. These forward-looking statements are based on management s current expectations and are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied in the forward-looking statements, including the impact of continued uncertainty and volatility in global economic conditions; supply and demand conditions in the hard drive industry; uncertainties concerning the availability and cost of commodity materials and specialized product components; actions by competitors; unexpected advances in competing technologies; uncertainties related to the development and introduction of products based on new technologies and expansion into new data storage markets; business conditions and growth in the various hard drive markets; pricing trends and fluctuations in average selling prices; and compliance with regulatory conditions imposed on us by the Chinese Ministry of Commerce. More information about the other risks and uncertainties that could affect our business are listed in our filings with the Securities and Exchange Commission (the SEC ) and available on the SEC s website at www.sec.gov, including our Annual Report on Form 10-K filed with the SEC on August 17, 2012, to which your attention is directed. In addition, our long-term financial goals included in this presentation are based upon a variety of estimates and assumptions which may not be realized and, in addition to the risks identified above, are inherently subject to business, economic, competitive, industry, regulatory, market and financial uncertainties, many of which are beyond our control. There can be no assurance that the assumptions made in preparing our long-term financial goals will prove accurate or will be achieved. The assumptions our management used as a basis for the long-term financial goals are not facts and should not be relied upon as being necessarily indicative of future results, and investors are cautioned not to place undue reliance on the these long-term financial goals. The forward-looking statements, including the long-term financial goals included in this presentation, speak only as of the date hereof. We do not intend, and we undertake no duty, to update these forward-looking statements to reflect subsequent events or circumstances; however, we may update our business outlook or long-term financial goals or any portion thereof at any time in our discretion. 2
