Forward Looking Statements 1 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:

• the possible impact of an impairment charge on the carrying value of the ST-Ericsson investment in our books of approximately $1.7 billion as well as on our consolidated results of the successful execution of ST-Ericsson's new strategic direction plan and its related savings announced on April 23rd 2012; • changes in demand in the key application markets and/or from key customers served by our products, including demand for products where we have achieved design wins and/or demand for applications where we are targeting growth, all of which make it extremely difficult to accurately forecast and plan our future business activities; • our ability in periods of reduced demand or visibility on orders to reduce our expenses as required, as well as our ability to operate our manufacturing facilities at sufficient levels with existing process technologies to cover our fixed operating costs; • our ability, in an intensively competitive environment, to identify and allocate necessary design resources to successfully develop and secure customer acceptance for new products meeting their expectations as well as our ability to achieve our pricing expectations for high-volume supplies of new products in whose development we have been, or are currently, investing; • the financial impact of obsolete or excess inventories if actual demand differs from our expectations as well as the ability of our customers to successfully compete in the markets they serve using our products; • our ability to maintain or improve our competiveness when a high percentage of our costs are fixed and are incurred in Euros and currencies other than U.S. dollars, especially in light of the increasing volatility in the foreign exchange markets and, more particularly, in the U.S. dollar exchange rate as compared to the Euro and the other major currencies we use for our operations; • the outcome of ongoing litigation as well as any new litigation to which we may become a defendant; • changes in our overall tax position as a result of changes in tax laws, expected income or the outcome of tax audits, changes in international tax treaties which may impact our results of operations as well as our ability to accurately estimate tax credits, benefits, deductions and provisions and to realize deferred tax assets; • the impact of intellectual property (“IP”) claims by our competitors or other third parties, and our ability to obtain required licenses on reasonable terms and conditions; • product warranty or liability claims based on epidemic or delivery failures or recalls by our customers for a product containing one of our parts; • availability and costs of raw materials, utilities, third-party manufacturing services, or other supplies required by our operations; and • current economic uncertainties involving the possibility during 2012 of limited growth or recession in global or important regions of the world economy, sovereign default, changes in the political, social, economic or infrastructure 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, earthquakes, tsunami, volcano eruptions or other acts of nature in, or affecting, the countries in which we, our key customers or our suppliers, operate and causing unplanned disruptions in our supply chain and reduced or delayed demand from our customers.

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,” “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, 2011, as filed with the SEC on March 5, 2012. 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.

• Free cash flow is defined as net cash from operating activities minus net cash from (used in) investing activities, excluding payment for purchases of and proceeds from the sale of marketable securities (both current and non-current), short-term deposits and restricted cash. We believe free cash flow provides useful information for investors and management because it measures our capacity to generate cash from our operating and investing activities to sustain our operating activities. Free cash flow is not a U.S. GAAP measure and does not represent total cash flow since it does not include the cash flows generated by or used in financing activities. In addition, our definition of free cash flow may differ from definitions used by other companies.

• Net financial position: resources (debt), represents the balance between our total financial resources and our total financial debt. Our total financial resources include cash and cash equivalents, net of bank overdrafts, if any, current and non-current marketable securities excluding Micron shares received in connection with the sales of Numonyx, short-term deposits and non-current restricted cash, and our total financial debt includes short term borrowings, current portion of long-term debt and long-term debt, all as reported in our consolidated balance sheet. We believe our net financial position provides useful information for investors because it givesevi dence of our global position either in terms of net indebtedness or net cash position by measuring our capital resources based on cash, cash equivalents and marketable securities and the total level of our financial indebtedness. Net financial position is not a U.S. GAAP measure.

• Return on Net Assets (RONA) is the ratio of operating income before impairment and restructuring charges divided by average net assets used during the period. ST defines average net assets as average total assets net of total liabilities as reported in our consolidated balance sheet excluding all items related to our financial position such as cash and cash equivalents, marketable securities, short term deposits, restricted cash, bank overdrafts, current portion of long term debt and long term debt.

• Operating income before impairment, restructuring and one time item excludes impairment, restructuring charges and other related closure costs and NXP Arbitration award.

• Operating income before impairment, restructuring and one-time item attributable to ST is calculated as operating income before impairment, restructuring and one time item excluding 50% of ST-Ericsson operating loss before impairment and restructuring as consolidated by ST. Operating margin before impairment, restructuring and one time item attributable to ST is calculated as operating income before impairment, restructuring and one time item attributable to ST divided by reported revenues excluding 50% of ST-Ericsson revenues as consolidated by ST. Return on Net Assets (RONA) attributable to ST is calculated as annualized operating income before impairment, restructuring and one time item attributable to ST divided by reported net assets excluding 50% of ST-Ericsson net assets as consolidated by ST.

• Adjusted net earnings and earnings per share (EPS) are used by our management to help enhance an understanding of ongoing operations and to communicate the impact of the excluded items. Adjusted earnings excludes impairment, restructuring charges and other related closure costs attributable to ST, the impact of equity investment divestiture and subsequent sale of Micron shares, other-than-temporary impairment (OTTI) charges and realized gain on financial assets, NXP Arbitration award net of the relevant tax impact.

• Consolidation of ST-Ericsson: ST-Ericsson, a joint venture owned 50% by ST, began operations on February 3, 2009 and is consolidated into ST’s operating results as of that date. ST- Ericsson is led by a development and marketing company consolidated by ST. A separate platform design company providing platform designs mostly to the development and marketing company is accounted for by ST using the equity method.

• Wireless Segment: As of February 3, 2009, “Wireless” includes the portion of sales and operating results of the 50/50 ST-Ericsson joint venture as consolidated in the Company’s revenues and operating results, as well as other items affecting operating results related to the wireless business.

• Sales recorded by ST-Ericsson and consolidated by ST are included in Telecom and Distribution
