This announcement contains forward-looking statements that address our expected future business and financial performance. These forward-looking statements are based on current expectations, estimates, forecasts and projections of future Company or industry performance, based on management’s judgment, beliefs, current trends and market conditions, and involve risks and uncertainties that may cause actual results to differ materially from those contained in the forward-looking statements. Accordingly, we caution you not to place undue reliance on these statements. Particular uncertainties that could materially affect future results include our ability to integrate and realize the expected benefits from our acquisition of LSI Corporation (“LSI”); any loss of our significant customers and fluctuations in the timing and volume of significant customer demand; global economic conditions and concerns; cyclicality in the semiconductor industry or in our target markets; increased dependence on the volatile, wireless handset market and on the enterprise storage market; delays, challenges and expenses associated with integrating acquired companies with our existing businesses and our ability to achieve the growth prospects and synergies expected from acquisitions we may make, including our recent acquisitions of LSI and PLX Technology, Inc.; quarterly and annual fluctuations in operating results; our competitive performance and ability to continue achieving design wins with our customers, as well as the timing of those design wins; our ability to sell to new types of customers and to keep pace with technological advances; market acceptance of the end products into which our products are designed; rates of growth in our target markets; our dependence on contract manufacturing and outsourced supply chain and our ability to improve our cost structure through our manufacturing outsourcing program; prolonged disruptions of our or our contract manufacturers’ manufacturing facilities or other significant operations; our dependence on outsourced service providers for certain key business services and their ability to

execute to our requirements; our ability to maintain or improve gross margin; our ability to maintain tax concessions in certain jurisdictions; our ability to protect our intellectual property and the unpredictability of any associated litigation expenses; any expenses or reputational damage associated with resolving customer product and warranty and indemnification claims; dependence on and risks associated with distributors of our products; the significant indebtedness incurred by us in connection with the LSI acquisition, including the need to generate sufficient cashflows to service and repay such debt; and other events and trends on a national, regional and global scale, including those of a political, economic, business, competitive and regulatory nature.
