STMicroelectronics Reports 2012 First Quarter Financial Results




-- First quarter net revenues of $2.02 billion


-- Free cash flow improved to $98 million in the first quarter*


-- Proposed cash dividend of $0.40 per share for 2012, stable with 2011

GENEVA, April 23, 2012 -- STMicroelectronics (NYSE: STM) reported financial results for the first quarter ended March 31, 2012.

First quarter net revenues decreased 8% to $2.02 billion on a sequential basis, while gross margin was 29.6%, absorbing anticipated
unsaturation charges related to fab loading and a one-time unexpected charge resulting from an arbitration award.

President and CEO Carlo Bozotti commented, "ST's wholly-owned businesses in the first quarter posted a sequential decrease
of 3%, better than historical seasonality, benefiting from growth in the Automotive segment and the Analog, MEMS and
Microcontrollers sector.

"Our Wireless segment losses weighed heavily on our quarterly results again. However, ST-Ericsson has announced today its
new strategic direction and renewed business model with a key objective to significantly reduce its operating losses
throughout 2012 as it moves towards leadership and improved financial returns.

"In total, first quarter activity levels across ST's product portfolio tracked closely to our expectations, with net revenues near
the mid-point of our business outlook. Similarly, gross margin evolution was consistent with our continued focus on
inventory management and in the first quarter gross margin absorbed approximately 600 basis points of unsaturation
charges and a one-time unexpected charge resulting from an arbitration award. The effort on inventory reduction and prudent
capital management led to a quarter on quarter increase in free cash flow and a further improvement in ST's financial position
which stood at $1.27 billion."*

First Quarter Review

ST's first quarter net revenues decreased 8.0% on a sequential basis, within our guidance, with ST's wholly-owned businesses posting
a sequential decrease of 3%, better than historical seasonality, while the Wireless product segment was lower by 29%. EMEA led all
regions with 8.9% sequential growth while the Americas decreased by 4.5%, Japan & Korea down by 8.8% and Greater China & South
Asia down by 16.7%.

Gross margin in the first quarter was 32.2%, excluding a one-time 260 basis point impact due to the charge on ST's cost of sales
following an award from an arbitration tribunal ordering ST to pay approximately $59 million to NXP Semiconductors as announced on
April 9, 2012. The first quarter gross margin was negatively impacted by an unsaturation charge of $71 million driven by inventory
reduction and a severe deterioration of manufacturing performance due to a low level of loading and less favorable than expected
product mix.

Combined SG&A and R&D expenses were $943 million compared to $894 million in the prior quarter mainly due to seasonality and
reduced activity in the prior quarter. Combined operating expenses, as a percentage of sales, were 46.8% in the 2012 first quarter
compared to 40.8% in the prior quarter.

Mainly due to increased losses at ST-Ericsson and excluding the one-time impact of the arbitration award, operating margin before
impairment, restructuring and one-time items attributable to ST was negative 6.5% in the 2012 first quarter compared to about break-
even in the prior quarter.*

In the first quarter of 2012, ST booked $159 million as a result attributable to non-controlling interests, which mainly included the 50%
owned by Ericsson in the ST-Ericsson joint venture, as consolidated by ST. In the fourth quarter of 2011, the corresponding amount
was $199 million.

First quarter net loss was $176 million or $(0.20) per share, compared to net loss of $(0.01) and net income of $0.19 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 $(0.14), excluding impairment and restructuring charges and the one-time impact of the arbitration award, in the first quarter,
compared to net loss of $(0.01) and net income of $0.20 per diluted share in the prior and year-ago quarters, respectively.*

operating results, as well as other items affecting operating results related to the wireless business.

(b) Net revenues of "Others" includes revenues from sales of Subsystems, assembly services and other revenues.

(c)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, NXP arbitration award 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 $71 million, $99 million and $2 million of unused capacity charges in the first quarter of 2012 and fourth and first quarters of
2011, respectively; and $18 million, $9 million and $24 million of impairment, restructuring charges and other related closure costs in
the first quarter of 2012 and fourth and first quarters of 2011, respectively.

Automotive (APG) first quarter net revenues increased 2% sequentially, mainly driven by market share gains and market improvement
in the U.S. and Japan. APG operating margin was 9.4% compared to 10.5% in the prior quarter.

Analog, MEMS and Microcontrollers (AMM) first quarter net revenues increased 1.5% sequentially driven by a solid recovery of
Microcontrollers and benefiting from an expanding product portfolio. AMM operating margin was 13.1% in the 2012 first quarter,
compared to 15.5% in the prior quarter.

Digital first quarter net revenues decreased 13.2% sequentially principally due to a significant decrease in imaging revenues related to
certain wireless customers and to a lesser extent seasonality. Digital operating margin was negative 11.2% in the 2012 first quarter,
compared to positive 2.4% in the prior quarter.

Power Discrete (PDP) first quarter net revenues decreased 8.2% sequentially principally reflecting a wireless customer specific
situation and still weak market conditions. PDP operating margin was negative 2.6% in the 2012 first quarter due to manufacturing
inefficiencies resulting from low fab loading compared to positive 6.4% in the prior quarter.

Wireless net revenues in the first quarter decreased 29% compared to the prior quarter due to a drop in sales of new products at one of
ST-Ericsson's largest customers, in addition to the usual seasonal effect and to the continued decline of ST-Ericsson's legacy products.
Wireless operating loss was $293 million in the first quarter, or $135 million after considering non-controlling interest, compared to a
loss of $211 million, or $93 million after considering non-controlling interest, in the prior quarter.

Second Quarter 2012 Business Outlook

Mr. Bozotti stated, "While there are still macro-economic uncertainties, we believe billings have bottomed in the first quarter.
Bookings have improved across the board during the course of the first quarter.

"Based on current visibility, we expect broad-based growth in all product segments during the second quarter leading to
revenue growth of about 7.5 percent at the mid-point of our guidance. Looking further ahead we also anticipate broad-based
revenue growth with a strong acceleration in MEMS and Analog in the second half of 2012 thanks to our new and innovative
products and our expanding customer base."

The Company expects second quarter 2012 revenues to grow sequentially in the range of about +7.5%, plus or minus 3 percentage
points. As a result, gross margin in the second quarter is expected to be about 34.4%, plus or minus 1.5 percentage points, and
assumes an improvement from the first quarter amount from fab loading and manufacturing performance.

This outlook is based on an assumed effective currency exchange rate of approximately $1.33 = euro 1.00 for the 2012 second quarter
and includes the impact of existing hedging contracts. The second quarter will close on June 30, 2012.

Recent Corporate Developments
Knights, Inc. named ST to its "Global 100 Most Sustainable Corporations" list for the third consecutive year. One of
Corporate
only three semiconductor companies so recognized, ST advanced 8 places to 75th place from its 83rd ranking in 2011.
ST assigned Carlo Ferro to ST-Ericsson as Chief Operating Officer to focus, along with ST-Ericsson President and CEO Didier
Lamouche, on the turnaround of ST-Ericsson. Mario Arlati, formerly ST's Chief Accounting Officer and head of corporate external

On April 5, an arbitration tribunal set up according to the rules of the International Chamber of Commerce, ordered ST to pay
approximately $59 million to NXP Semiconductors B.V. concerning a dispute related to a claim from NXP for underloading
charges to be included in the price of wafers which NXP supplied to ST's wireless JV. The tribunal chose not to address certain
issues raised by ST that will be part of a second arbitration between the same ICC tribunal scheduled for June 2012, with a final
decision coming within 12 months. Though the award has been recognized in these Q1 results, ST intends to vigorously pursue
its claims in the second arbitration aiming to convince the tribunal to reverse the economic effect of its first arbitration award.
On April 16, ST announced the main resolutions to be submitted for shareholder approval at the Company's Annual General
Meeting, which will be held in Amsterdam on May 30, 2012. The main resolutions, proposed by the Supervisory Board, include:

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 (loss) before, impairment, restructuring and one-time items 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 the sale of Micron shares, other-than-temporary impairment (OTTI) charges
on financial assets, NXP arbitration award, 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, bank overdrafts, current portion of long-term debt and long-term debt.

Operating income (loss) before impairment, restructuring and one-time items attributable to ST is calculated as operating income (loss)
before impairment, restructuring and one-time items excluding 50% of ST-Ericsson operating income (loss) before impairment,
restructuring and one-time items as consolidated by ST. Operating margin before impairment, restructuring and one-time items
attributable to ST is calculated as operating income (loss) 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 (loss)
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, current and non-current marketable securities, short-term deposits and
restricted cash, and our total financial debt includes bank overdrafts, if any, 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 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.
