ST delivered significant year-over-year improvements in profitability measures with operating income up 90%, operating margin expanding 320 basis points, and earnings per share more than doubling. Specifically, for the 2006 third quarter, the Company reported operating income of $194 million, an operating margin of 7.7% (8.5% excluding restructuring and impairment charges), and net income of $207 million, or $0.22 per diluted share. In the year-ago quarter, the Company reported operating income of $102 million, equal to an operating margin of 4.5% (5.1% excluding restructuring and impairment charges), and net income of $89 million or $0.10 per share. In the prior quarter, the Company reported operating income of $169 million, operating margin of 6.8% (8.1% excluding restructuring and impairment charges), and net income of $168 million or $0.18 per diluted share.

The Company posted $20 million of impairment, restructuring charges, and other related closure costs during the 2006 third quarter related to restructuring plans and intangible asset impairment, representing an after-tax impact of approximately $0.02 per share. In the prior quarter, restructuring-related expenses were $34 million and $12 million in the year-ago quarter.

In addition, 2006 third quarter income tax expenses were reduced by approximately $23 million arising from certain tax credits.

In the third quarter of 2006, the effective average exchange rate for the Company was approximately $1.255 to €1, compared to $1.23 to €1 in the second quarter of 2006 and $1.30 to €1 in the year-ago quarter. The Company’s effective exchange rate reflects actual exchange rate levels combined with the impact of hedging programs.

Cash Flow and Balance Sheet Highlights
Net cash from operating activities in the third quarter was $555 million and $1,932 for the first nine months of 2006. Capital expenditures were $451 million in the 2006 third quarter and $1,147 million for the first nine months, compared to $284 million and $1,211million in the 2005 similar periods, respectively. Net operating cash flow* was $81 million for the third quarter, compared to $173 million in the year-ago quarter, and $241 million in the prior quarter. In the first nine months of 2006, ST had $509 million in net operating cash flow compared to -$20 million in the 2005 first nine months.

At September 30, 2006, ST’s cash and cash equivalents, marketable securities, and short-term deposits equaled $2.6 billion, after the payment of approximately $1.4 billion for the early redemption of the 2013 convertible bonds. Total debt was $1.9 billion. ST’s net financial position** improved by approximately $82 million sequentially to $621 million. Shareholders’ equity was $9.3 billion at September 30, 2006.

(*) Net operating cash flow is a non-US GAAP metric, which the Company’s management utilizes as a measure of cash generation capability. It is defined as net cash from operating activities ($555 million in the third quarter of 2006) minus net cash used in investing activities excluding payments for purchase of and proceeds from the sale of marketable securities and proceeds from matured short-term deposits ($474 million in the third quarter of 2006).

(**) Net financial position is a non-US GAAP metric used by the Company’s management to help assess financial flexibility. It is defined as cash and cash equivalents, marketable securities, and short-term deposits ($2,559 million) minus total debt (bank overdrafts $0 million + current portion of long-term debt $139 million + long-term debt $1,799 million).

President and CEO Remarks
Carlo Bozotti, President and CEO, commented, “ST is making important progress across our three major initiatives – product portfolio, market share, and returns on invested capital.

“We are strengthening our Application Specific Product Groups (ASG), which represent over half of ST’s revenues, through a more focused R&D effort. This is translating into improved revenue and operating margin performance, as year-to-date ASG’s revenues are up 10% with their operating income up 50%, and the operating margin moving toward double-digits.

“Moreover, we are further enhancing the performance of our Micro, Power and Analog group (MPA), with revenue higher by almost 19%, operating income up 27%, and an operating margin of 15.7% for the first nine months of 2006.

“ST’s year-to-date sales growth of 13.5%, compared to estimates of industry growth of about 8.5%, confirms the inflection point we achieved last year when we began to regain market share. This revenue expansion demonstrates the Company’s reestablished market leadership, and confirms the benefits to date of our sales and marketing initiatives in combination with our more robust, and still improving, product portfolio.

“Finally, we are keenly focused on careful management of capital investments. This is visible through our steady RONA improvement in each quarter of 2006 and capital intensity trends over the last two years. In the third quarter, RONA increased again from second quarter levels, largely driven by gross margin expansion, and at about 10%, is similar to our weighted average cost of capital. In addition, we anticipate that our 2006 capital spending will be $1.6 billion - $200 million lower than we had originally planned. This will improve the 2006 capex-to-sales ratio for ST to about 16%, as we have been able to meet our investment needs through more efficient use of our resources worldwide.”

Additional Third Quarter 2006 Financial and Operating Data
The following table and commentary provide a breakdown of revenues and operating income by product segment.

Net Revenues and Operating Income by Product Group Segment:

* Automotive; Computer Peripheral; and Home, Personal, and Communication products
** Effective January 1, 2006 the Microcontroller, Linear and Discrete (MLD) Group was renamed as the Micro, Power and Analog (MPA) product segment to better reflect product portfolio focus and increased capabilities in advanced Analog. No change occurred in the Group’s perimeter or organization.

(1) Net revenues of “Others” include revenues from sales of Subsystems and other products not allocated to product segments.

(2) Operating loss of “Others” includes items such as impairment, restructuring charges, and other related closure costs, start-up costs, and other unallocated expenses such as strategic or special research and development programs, certain corporate-level operating expenses, certain patent claims and litigations, and other costs that are not allocated to the product segments, as well as operating earnings or losses of the Subsystems and Other Products segment. Certain costs, mainly R&D, formerly in the “Others” category, have been allocated to the segments.

Sequentially, Application Specific Product Groups’ revenues increased 0.2%, MPA sales increased 6.3%, and MPG sales declined 2.8%. Operating profit increased to $125 million for Application Specific Product Groups and $107 million for MPA. Operating profit was $10 million in MPG.

First Nine Months 2006 Net Revenues and Operating Income by Product Group Segment:

*, **, (1) and (2) defined in earlier table.

Outlook
Mr. Bozotti stated, “As we enter the fourth quarter, we see some correction in the current semiconductor cycle. The result is that we expect sequential revenue growth below our historical levels reflecting wireless and automotive sales below normal seasonal trends. For the fourth quarter ST expects sequential sales growth in the range between -1% and 5%.
Nonetheless, ST will have double-digit revenue growth for 2006, a clear and unambiguous sign of our market-share resurgence. And we believe ST is poised to continue gaining share beyond the current year, as well.

“Despite this quarterly sales outlook, we expect the continuation of our margin progression with the fourth quarter gross margin to be about 37%, plus or minus one percentage point.”

These objectives are based on an assumed currency exchange rate for the Company of approximately $1.265 = €1 for the 2006 fourth quarter, which reflects current exchange rate levels combined with the impact of existing hedging contracts.

Recent Corporate Developments
On August 7 2006, ST redeemed $1,397 million in aggregate principal of its 2013 Zero Coupon convertible bonds, representing substantially all of the outstanding 2013 convertible bonds.
