Earnings Release • Jan 23, 2012

-- Return to positive free cash flow of \$47 million in the fourth quarter*

-- Record 2011 revenues for automotive applications and MEMS

-- Net revenues of \$9.73 billion and net income of \$650 million for full year 2011

PARIS, Jan. 23, 2012 -- STMicroelectronics (NYSE: STM) reported financial results for the fourth quarter and full year ended December 31, 2011.

President and CEO Carlo Bozotti commented, "In 2011, our wholly-owned businesses delivered a solid performance throughout the year, within the backdrop of a severe slowdown in the broader semiconductor market as the year evolved. ST's whollyowned businesses delivered revenue of \$8.2 billion and an operating margin of 11.4%.

"Moreover, we expected to see strong growth during 2011 in two of our key strategic product areas and we are particularly proud of our achievements there. Our MEMS sales nearly doubled to over \$600 million. Our automotive business reported record revenues, with sales up 18% during 2011, on top of sales growth of over 40% during 2010. In both areas, revenue growth was also accompanied by a significant expansion of the operating profitability of these product groups.

"We also continued to maintain a strong financial position and sharp focus on capital management. Exiting the year, our financial resources totaled \$2.3 billion and our net financial position was about \$1.17 billion, as adjusted, taking into account the 50% of ST-Ericsson's debt. As anticipated, we saw an improvement in the fourth quarter in inventory levels and inventory turns and capital expenditures are back down to much lower levels as planned.

"For ST-Ericsson, managing the wireless joint venture's shift from a legacy portfolio to the new product roadmap has proven more challenging than expected given the change in the business of one of their largest customers and its evolving plans. While the new portfolio is beginning to ramp, the current results of ST-Ericsson are still distant from the financial prospects we are envisioning. Therefore, ST-Ericsson is now in a crucial phase focusing on improving execution, lowering its breakeven point and reviewing its roadmap to sustainable profitability. We are confident that the newly appointed Chief Executive Officer of ST-Ericsson is the appropriate leader to drive this turnaround."

Fourth Quarter Review

_____

ST's fourth quarter net revenues decreased 10.3% on a sequential basis, within our guidance, with all regions down sequentially. The Americas decreased 4.6%, Japan & Korea and Greater China & South Asia each were down about 7.5% and EMEA decreased 20.7%. On a year-over-year basis, ST's net revenues decreased 22.6%, with Analog, MEMS and Microcontrollers (AMM) and Automotive, Computer, Consumer and Communications Infrastructure (ACCI), led by Automotive, performing better than the other segments, in particular Wireless.

As expected, gross margin decreased 240 basis points compared to the prior quarter, principally due to lower volumes that were associated with the reduction in inventory that resulted in the underloading of ST's wafer fabs. On a year-over-year basis, gross margin declined by 650 basis points also mainly due to lower volumes, and related charges for unused capacity.

Combined SG&A and R&D expenses of \$894 million in the fourth quarter were substantially flat compared to the prior quarter. On a

year-over-year basis, combined expenses decreased \$20 million reflecting the restructuring at ST-Ericsson, among other factors. Combined operating expenses, as a percentage of sales, were 40.8% in the 2011 fourth quarter compared to 36.8% and 32.3% in the prior and year-ago quarters, respectively.

Due to market conditions driving lower volumes and the resulting unsaturation, operating margin before restructuring attributable to ST was about break-even in the 2011 fourth quarter compared to 4.3% and 12.4% in the prior and year-ago quarters.*

Income tax in the fourth quarter includes a \$92 million charge for a valuation allowance related to ST-Ericsson's accumulated Net Operating Losses. As this allowance does not relate to ST's investment in ST-Ericsson, minority interests increases by the same amount of \$92 million, with no impact to ST's consolidated income. Absent this allowance, the ST tax rate for the fourth quarter would be 15%.

Fourth quarter net loss was \$11 million or \$(0.01) per share, compared to net income of \$0.08 and \$0.24 per diluted share in the prior and year-ago quarters, respectively. On an adjusted basis, net of related taxes, ST reported non-U.S. GAAP net loss per share of \$(0.01) in the fourth quarter, compared to net income of \$0.09 and \$0.27 per diluted share in the prior and year-ago quarters, respectively.*

For the 2011 fourth quarter, the effective average exchange rate for the Company was approximately \$1.36 to euro 1.00 compared to \$1.40 to euro 1.00 for the 2011 third quarter and \$1.34 to euro 1.00 for the 2010 fourth quarter.

TOTAL	2,191	(132)	2,442	(23)	2,833	213

ACCI, AMM and PDP were all negatively impacted in the fourth quarter of 2011 by weak market conditions, which resulted in a revenue decrease as compared to both the prior and year-over-year quarters, and lower margins mainly due to reduced volumes.

ACCI fourth quarter net revenues decreased about 10% compared to the prior quarter and about 21% on a year-over-year basis, which was also negatively impacted by ST's planned exit from hard disk drive system-on-chip. Despite the lower level of revenues, ACCI operating margin was 6.1% compared to 7.1% and 12.1% in the prior and year-ago quarters, respectively.

⁽a) Reflecting the transfer of a small business unit from ACCI to AMM as of January 1, 2011, the Company has reclassified prior period revenues and operating income results from ACCI to AMM.

⁽b) Wireless includes the portion of sales and operating results of ST-Ericsson as consolidated in the Company's revenues and operating results, as well as other items affecting operating results related to the wireless business.

(c) Net revenues of "Others" includes revenues from sales of Subsystems, assembly services and other revenues. (d) Operating income (loss) of "Others" includes items such as unused capacity charges, impairment, restructuring charges and other related closure costs, phase out and start-up costs, and other unallocated expenses such as: strategic or special research and development programs, certain corporate-level operating expenses, patent claims and litigations, and other costs that are not allocated to product groups, as well as operating earnings or losses of the Subsystems and Other Products Group. "Others" includes \$99 million, \$42 million and \$2 million of unused capacity charges in the fourth and third quarters of 2011 and fourth quarter of 2010, respectively; and \$9 million, \$10 million and \$32 million of impairment, restructuring charges and other related closure costs in the fourth and third quarters of 2011 and fourth quarter of 2010, respectively.

AMM fourth quarter net revenues decreased by approximately 12% compared to the prior quarter. On a year-over-year basis, AMM revenues decreased by about 19%. AMM operating margin, showing resilience, was 17.7% in the 2011 fourth quarter, compared to 19.9% and 24.4% in the prior and year-ago quarters, respectively.

PDP fourth quarter net revenues decreased 20% sequentially and 31% on a year-over-year basis, reflecting mainly weak market conditions. In the 2011 fourth quarter, PDP operating margin was 6.4% compared to 10.6% and 17.2% in the prior and year-ago quarters, respectively, mainly due to lower volumes and price erosion.

Wireless net revenues in the fourth quarter decreased 0.8% sequentially and 27% year-over-year. In the fourth quarter, Sharp announced new smartphones based on ST-Ericsson's Thor™ modem and Nokia selected the NovaThor™ platform for future devices based on the Windows Phones mobile platform. Wireless operating loss was \$211 million in the fourth quarter, out of which \$93 million is for ST's competence, compared to an operating loss of ST's competence of \$106 million and \$64 million in the prior and year-ago period, respectively. Non-controlling interest is recorded below operating results in ST's Consolidated Income Statement and reflects primarily Ericsson's 50% share in the joint venture's results, as consolidated by ST.

ST-Ericsson is currently in a shift from legacy to new products. Though their path to success is challenging, ST-Ericsson is continuing to focus on securing the successful execution and delivery of their new products to customers while lowering its break-even point.

The changes in the business environment at a large customer during 2011 have reduced demand for legacy products and are delaying the ramp of new products with that customer. As ST-Ericsson does not yet have the adequate level of sales, the company's path to improve its financial performance is expected to take longer. Additionally, ST-Ericsson has recently increased its focus on execution.

ST-Ericsson's very recently appointed Chief Executive Officer and leadership team have been requested by the Parent Companies to review its strategic plan and financial prospects. ST, together with our partner Ericsson, is firmly committed to support ST-Ericsson in the transition to turn-over to sustainable profitability and cash generation.

As a result of this strategic review we may consider additional actions to solidify and accelerate ST-Ericsson's path to profitability. In such an event, or in case of a significant worsening of business prospects, the value of ST-Ericsson for ST could decrease to a value significantly lower than the current carrying amount of ST-Ericsson on our books and we may be required to take an impairment charge.

We will continuously monitor ST-Ericsson's business evolution and we will evaluate their progress on a regular basis.

Cash Flow and Balance Sheet Highlights

_____

Free cash flow improved sequentially to positive \$47 million in the fourth quarter, principally due to lower capital expenditures and the reduction of inventory and despite the results of ST-Ericsson, compared to a negative \$136 million and a positive \$349 million in the prior and year-ago quarters, respectively.*

As anticipated, capital expenditures in the fourth quarter decreased significantly to \$76 million compared to \$384 million and \$423 million in the prior and year-ago quarters, respectively.

Inventory decreased by \$170 million to \$1.53 billion at year end. In the fourth quarter inventory turns improved to 3.8.

In the fourth quarter, dividends paid to shareholders were \$89 million. In addition, the Company paid \$199 million to redeem a portion of its 2016 convertible bond.

(*)Free cash flow is a non-U.S. GAAP measure. For additional information, please refer to Attachment A.

Total equity, including non-controlling interest, was \$8.0 billion at year end.

ST's net financial position, adjusted taking into account our 50% investment in ST-Ericsson, was a net cash position of \$1,167 million at December 31, 2011 compared to \$1,134 million at October 1, 2011 and \$1,227 million at December 31, 2010. ST's cash and cash equivalents, short-term deposits, marketable securities and restricted cash equaled \$2.33 billion and total debt, including 100% of ST-Ericsson's debt, as consolidated by ST, was \$1.57 billion at December 31, 2011.*

2011 Full Year Review

Net revenues for the full year 2011 decreased 5.9% to \$9.73 billion from \$10.35 billion in the prior year reflecting weak market conditions, particularly in the second half of the year, and ST-Ericsson's transition from legacy to new products. ST wholly-owned businesses' net revenues increased about 1% in 2011.

In 2011, AMM grew within the frame of a strong slowdown in the semiconductor industry recorded in the second half of 2011, while both ACCI and PDP decreased. AMM's net revenues, mainly driven by strong growth in MEMS, increased 7.5%, accompanied by an increase in its operating margin to 20.3% from 18.8% in 2010. ACCI's net revenues decreased 1.4%, strong growth in Automotive and Imaging being offset by weak market conditions, particularly in Consumer, throughout the year, as well as the planned exit from hard disk drive system-on-chip and its operating margin decreased to 8.9% compared to 10.0% in 2010. PDP's net revenues decreased 6% and its operating margin was 11.2%, compared to 13.6% in 2010 due to weak industry conditions as well as a specific situation at one customer. Wireless revenues decreased 30% and the operating loss increased by approximately 68%.

Gross margin was 36.7% of net revenues for the full year 2011, compared to 38.8% of net revenues in 2010, mainly due to prices and lower fab loading and unused capacity charges incurred in the 2011 third and fourth quarters. Operating expenses were about flat. Net income, as reported, was \$650 million in 2011, or \$0.72 diluted per share, mainly due to the after-tax gain of \$308 million related to the cash payment from Credit Suisse as the full and final settlement of all outstanding litigation concerning auction-rate securities, compared to net income of \$830 million, or \$0.92 diluted per share in 2010. On an adjusted basis, net of related taxes, ST reported non-U.S. GAAP diluted net earnings per share of \$0.41 in 2011 compared to \$0.75 per share in 2010.*

On a year-over-year basis, the effective average exchange rate for the Company was approximately \$1.37 to euro 1.00 for 2011, compared to \$1.36 to euro 1.00 for 2010.

First Quarter 2012 Business Outlook

Mr. Bozotti stated, "Based on current visibility, we believe bookings have bottomed. Looking to the first quarter, we expect billings to bottom, as we see stronger than seasonal billings for ST's wholly-owned businesses offset by a very significantly weaker revenue performance from ST-Ericsson.

"Preliminary industry analysts' forecasts indicate that the overall semiconductor market should stabilize in 2012. For ST, we see the opportunity to continue to grow in selected markets during 2012 but we remain concerned about the macro-economic uncertainty. Consequently, we plan in the near-term to continue to maintain reduced levels of loading at our facilities. We will continue to focus on capital management, taking a prudent approach with respect to inventory levels and capital investments, with the goal of maintaining and expanding our free cash flow. In addition, we are continuing to bring to market new innovative products to drive market share gains."

Based largely upon a very significantly weaker sequential sales outlook for wireless, the Company anticipates total revenues to sequentially decrease about 4% to 10% in first quarter of 2012. As a result, and reflecting an improved, but still high level of unsaturation at our facilities, gross margin in the first quarter is expected to be about 33.0%, plus or minus 1.5 percentage points.

This outlook is based on an assumed effective currency exchange rate of approximately \$1.32 = euro 1.00 for the 2012 first quarter and includes the impact of existing hedging contracts. The first quarter will close on March 31, 2012.

Corporate Developments

• In the quarter ST announced the establishment of "ST New Ventures," a corporate venture-capital fund targeting investments in technology, product and service start-up companies mainly in the Healthcare, Cleantech and Smart Infrastructure areas. The fund will enable the Company to be close to new markets where semiconductors are key and to be at the leading edge of innovation and new applications.
• In order to unlock additional growth potential, ST re-aligned its organization to ensure an even more customer-oriented approach, further increase the effectiveness of its Research and Development and manufacturing activities, and more closely associate the businesses with its vision and product strategy.

With Didier Lamouche having accepted the full-time responsibility to run ST-Ericsson, all of ST's regional marketing and sales organizations now report directly to President and CEO Carlo Bozotti. Executive Vice President Paul Grimme, who had previously led ST's Automotive Product Group (APG), has moved to take on the role of General Manager Sales and Marketing Europe, the Middle East, and Africa.

The importance of R&D and manufacturing to ST is highlighted by consolidating Technology R&D, Front-End Manufacturing, Packaging & Test Manufacturing, Product Quality Excellence, and Global IT under the direction of Senior Executive Vice President Jean-Marc Chery to exploit the synergies of these organizations.

ST also reorganized its product groups into the Industrial and Multisegment (IMS) and Digital Sectors and a separate Automotive Product Group that reinforce the Company's vision to be the worldwide leader in Sense & Power and Multimedia Convergence. Within these groups, Benedetto Vigna has been appointed Corporate Vice President and General Manager of the Analog, MEMS, and Sensors Group and Marco Monti has been appointed Corporate Vice President and General Manager of the Automotive Product Group.

STMicroelectronics Supplemental Non-U.S. GAAP Financial Information U. S. GAAP – Non-U.S. GAAP Reconciliation In Million US\$ Except Per Share Data

The supplemental non-U.S. GAAP information presented in this press release is unaudited and subject to inherent limitations. Such non-U.S. GAAP information is not based on any comprehensive set of accounting rules or principles and should not be considered as a substitute for U.S. GAAP measurements. Also, our supplemental non-U.S. GAAP financial information may not be comparable to similarly titled non-U.S. GAAP measures used by other companies. Further, specific limitations for individual non-U.S. GAAP measures, and the reasons for presenting non-U.S. GAAP financial information, are set forth in the paragraphs below. To compensate for these limitations, the supplemental non-U.S. GAAP financial information should not be read in isolation, but only in conjunction with our consolidated financial statements prepared in accordance with U.S. GAAP.

Operating income before restructuring is used by management to help enhance an understanding of ongoing operations and to communicate the impact of the excluded items, such as impairment, restructuring charges and other related closure costs. Adjusted net earnings and earnings per share (EPS) are used by management to help enhance an understanding of ongoing operations and to communicate the impact of the excluded items like impairment, restructuring charges and other related closure costs attributable to ST, the impact of sale of Micron shares, net of the relevant tax impact.

Return on net assets (RONA) is considered by management to be the key financial and economic metric to measure the return on invested capital. 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 restructuring attributable to ST is calculated as operating income before restructuring excluding 50% of ST-Ericsson operating income (loss) before restructuring as consolidated by ST. Operating margin before restructuring attributable to ST is calculated as operating income before restructuring attributable to ST divided by reported revenues excluding 50% of ST-Ericsson revenues as consolidated by ST. RONA attributable to ST is calculated as annualized operating income before restructuring attributable to ST divided by reported net assets excluding 50% of ST-Ericsson net assets as consolidated by ST.

The Company believes that these non-GAAP financial measures provide useful information for investors and management because they measure the Company's capacity to generate profits from its business operations, excluding the effect of acquisitions and expenses related to the rationalizing of its activities and sites that it does not consider to be part of its on-going operating results, thereby offering, when read in conjunction with the Company's GAAP financials, (i) the ability to make more meaningful period-to-period comparisons of the Company's on-going operating results, (ii) the ability to better identify trends in the Company's business and perform related trend analysis, and (iii) an easier way to compare the Company's results of operations against investor and analyst financial models and valuations, which usually exclude these items.

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, 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 if any, bank overdrafts, 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 gives evidence 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.

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.
