Use of Supplemental Non-U.S. GAAP Financial Information

This press release contains supplemental non-U.S. GAAP financial information, including adjusted operating income (loss), adjusted net earnings (loss), adjusted net earnings (loss) per share, net operating cash flow and net financial position.  

Readers are cautioned that these measures are unaudited and not prepared in accordance with U.S. GAAP and should not be considered as a substitute for U.S. GAAP financial measures. In addition, such non-U.S. GAAP financial measures may not be comparable to similarly titled information by other companies.

See Attachment A of this press release for a reconciliation of the Company's non-U.S. GAAP financial measures to their corresponding U.S. GAAP financial measures. To compensate for these limitations, the supplemental non-U.S. GAAP financial information should not be read in isolation, but only in conjunction with the Company's consolidated financial statements prepared in accordance with U.S. GAAP.

Forward-looking information

Some of the statements contained in this release that are not historical facts are statements of future expectations and other forward-looking statements (within the meaning of Section 27A of the Securities Act of 1933 or Section 21E of the Securities Exchange Act of 1934, each as amended) that are based on management's current views and assumptions, and are conditioned upon and also involve known and unknown risks and uncertainties that could cause actual results, performance or events to differ materially from those in such statements due to, among other factors:

• Significant changes in demand in the key application markets and from key customers served by our products make it extremely difficult to accurately forecast and plan our future business activities. In particular following a period of significant order cancellations, we recently experienced  a strong surge in customer demand, which is leading to capacity constraints in certain applications;
• our ability to utilize and operate our manufacturing facilities at sufficient levels to cover fixed operating costs in periods of reduced customer demand  as well as to ramp up production efficiently and rapidly  to respond to increased customer demand, as well as the financial impact of obsolete or excess inventories if actual demand differs from our expectations;
• the impact of intellectual-property claims by our competitors or other third parties, and our ability to obtain required licenses on reasonable terms and conditions;
• our ability to successfully integrate the acquisitions we pursue, in particular the successful integration and operation of  the ST-Ericsson joint venture;
• we hold significant non-marketable equity investments in Numonyx, our joint venture in the flash-memory market segment, and in the ST-Ericsson joint venture. Additionally, we are a guarantor for certain Numonyx debts. Therefore, further declines in these market segments or the inability of Numonyx and /or ST-Ericsson to successfully compete could result in further significant impairment charges, restructuring charges and gains/losses on equity investments;
• our ability to compete in our industry since a high percentage of our costs are fixed and are incurred in currencies other than U.S. dollars, especially in light of the volatility in the foreign exchange markets and more particularly in the rate of the U.S. Dollar compared to the other major currencies which we use for our operations;
• our ability to execute our restructuring initiatives in accordance with our plans if unforeseen events require adjustments or delays in implementation or require new plans;
• our ability in an intensively competitive environment to secure customer acceptance and to achieve our pricing expectations for high-volume supplies of new products in whose development we have been, or are currently, investing;
• changes in the political, social or economic environment, including as a result of military conflict, social unrest and/or terrorist activities, economic turmoil, as well as natural events such as severe weather, health risks, epidemics or earthquakes in the countries in which we, our key customers or our suppliers, operate;
• the outcome of ongoing litigation as well as any new litigation to which we may become a defendant; and
• changes in our overall tax position as a result of changes in tax laws or the outcome of tax audits, and our ability to accurately estimate tax credits, benefits, deductions and provisions and to realize deferred tax assets.

Such forward-looking statements are subject to various risks and uncertainties, which may cause actual results and performance of our business to differ materially and adversely from the forward-looking statements. Certain forward-looking statements can be identified by the use of forward-looking terminology, such as "believes," "expects," "may," "are expected to," "will," "will continue," "should," "would be," "seeks" or "anticipates" or similar expressions or the negative thereof or other variations thereof or comparable terminology, or by discussions of strategy, plans or intentions. Some of these risk factors are set forth and are discussed in more detail in "Item 3. Key Information — Risk Factors" included in our Annual Report on Form 20-F for the year ended December 31, 2008, as filed with the SEC on May 13, 2009. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described in this release as anticipated, believed or expected. We do not intend, and do not assume any obligation, to update any industry information or forward-looking statements set forth in this release to reflect subsequent events or circumstances.
