Geneva, October 23, 2007 - STMicroelectronics (NYSE: STM) reported financial results for the third quarter and nine months ended September 29, 2007. On May 22, 2007, ST, in conjunction with Intel and Francisco Partners, announced a definitive agreement to create an independent semiconductor company, with ST contributing its Flash Memories Group (FMG). Since January 1, 2007 ST’s NOR and NAND Flash businesses have been organized into a stand-alone segment, in anticipation of strategic repositioning. In this press release, ST will present certain financial results for the Company as a whole, as well as for the Company excluding FMG.

Third Quarter Net Revenues and Gross Profit Review

In Million US$ and %	Q3 2007
	ST	ST excluding FMG
Net Revenues	$2,565	$2,213
Sequential Growth	6.1%	6.1%
Year-over-Year Growth	2.1%	3.7%

Net revenues for the third quarter increased 6.1% sequentially to $2,565 million from the $2,418 million reported in the prior quarter, with growth led by application-specific wireless and computer products. Excluding FMG, net revenues also increased 6.1% sequentially.

In the 2007 third quarter, following a comprehensive review of employee benefit plans, the Company revised its accounting for a seniority award program existing at a large affiliate since 1986. Historically, charges were expensed when incurred and are now accrued over the service period of the employee. In connection with this change the Company incurred a one-time, non-cash, pre-tax charge for past periods of about $21 million, of which more than $7 million are in cost of goods sold, more than $8 million are in R&D and nearly $5 million are in SG&A expenses. This revision to methodology had no material impact on prior periods.

Gross profit was $902 million for the 2007 third quarter and the gross margin was 35.2%. Before the seniority program charge, gross margin was 35.5%. Sequentially, both gross profit and gross margin improved from the prior quarter levels of $838 million and 34.7%, respectively. Excluding FMG, gross profit was $865 million for the 2007 third quarter, representing a gross margin improvement to 39.1%, compared to 37.8% in the second quarter. Gross margin improvement in the quarter reflected better mix and manufacturing performance, while only incorporating a portion of the recent exchange rate degradation. In the year-ago quarter, the gross profit for the entire Company was $904 million and the gross margin was 36.0%.

President and CEO Carlo Bozotti commented, “ST’s third quarter financial results came well in line with our expectations. Net revenues increased 6.1% sequentially, at the high end of our outlook range of 2% to 7%, and gross margin was in the middle of our range excluding the one time charge. Without the Flash Memories Group (FMG), gross margin reached 39.1%.

“Our Application Specific Groups (ASG), which represented 54% of net revenues, posted the largest sequential quarterly improvements in both sales and operating income. ASG sales were up 7% sequentially on double-digit wireless and computer performance. Reflecting a more favorable product mix, as well as manufacturing cost improvements, ASG’s operating income increased about $90 million sequentially, leading to an operating margin over 10% for the 2007 third quarter.

“ASG’s performance in combination with good operating leverage in the third quarter from our Industrial and Multisegment Sector (IMS) resulted in ST’s return on net assets (RONA), excluding FMG, reaching nearly 14%.

“We are moving towards the completion of the divestiture of our Flash Memories Group, which will become part of a new independent semiconductor company, Numonyx. Based upon current information, we anticipate the closing of the transaction during the fourth quarter, in line with the initial timetable.”

Operating Expenses
Combined selling, general & administrative and research & development expenses represented 27.8% of net revenues in the third quarter, lower than the 29.6% in the second quarter of 2007, and somewhat above the 27.2% in the year-ago quarter. R&D expenses of $442 million in the 2007 third quarter were focused on product development while SG&A expenses of $272 million for the 2007 third quarter were achieved by cost-control efforts and seasonal benefits despite currency and stock- based compensation effects. Excluding the one-time third quarter charge, R&D and SG&A were $433 million and $268 million respectively, and combined were 27.3% of quarterly net revenues.

Operating Income and Profit Margin, Net Income and Earnings per Share
For the 2007 third quarter, the Company reported operating income of $181 million, an operating margin of 7.0% (9.1% excluding seniority program and restructuring and impairment charges of $21 million and $31 million respectively), and net income of $187 million, or $0.20 per diluted share ($0.24 excluding seniority program and restructuring and impairment charges). In the year-ago quarter, the Company reported operating income of $194 million, equal to an operating margin of 7.7% (8.5% excluding restructuring and impairment charges of $20 million), and net income of $207 million or $0.22 per share ($0.24 excluding restructuring and impairment charges). In the prior quarter, the Company reported an operating loss of $772 million, reflecting $906 million of impairment, restructuring charges and other related closure costs primarily associated with the Company’s plans to divest the FMG group. Excluding such costs, second quarter operating income was $134 million, operating margin was 5.5% and net income was $139 million or $0.15 per diluted share.

In the third quarter of 2007, the effective average exchange rate for the Company was approximately $1.36 to €1, compared to $1.335 to €1 in the second quarter of 2007 and $1.255 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 was $511 million in the third quarter and $1,451 million for the first nine months of 2007. Net operating cash flow* was $255 million for the third quarter, compared to $225 million in the prior quarter and $81 million in the year-ago quarter. For the first nine months, net operating cash flow* totaled $652 million, up from $509 million in the 2006 similar period.

Reflecting ST’s successful progress in its lighter asset policy, capital expenditures were significantly lower for the quarter and year-to-date periods in comparison to the respective 2006 periods. Specifically, capital expenditures were $228 million in the 2007 third quarter and $735 million for the first nine months of 2007, compared to $451 million and $1,147 million for the 2006 similar periods.

At September 29, 2007, ST’s cash and cash equivalents, marketable securities, short-term deposits and restricted cash equaled $3.3 billion. Total debt was $2.2 billion. ST’s net financial position** was $1.1 billion. Shareholders’ equity was $9.3 billion.

* 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 ($511 million in the third quarter of 2007) minus net cash used in investing activities (primarily capital expenditures) excluding restricted cash, payments for purchase of and proceeds from the sale of marketable securities and investment in and proceeds from matured short-term deposits ($256 million in the third quarter of 2007).
** 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, short-term deposits and restricted cash ($3,289 million) minus total debt (bank overdrafts $0 million + current portion of long-term debt $74 million + long-term debt $2,099 million).

Net Revenues by Market Segment for Q3 2007
The following table estimates, within a variance of 5% to 10% in the absolute dollar amount, the relative weighting of each of the Company’s target market segments for the third quarter of 2007.

First Nine Months 2007 Results

Net revenues for the first nine-months were $7,258 million, a decrease of 1.5% compared to 2006 first nine-month revenues of $7,371 million. Excluding FMG, sales were 1.3% higher than last year’s first nine-months.
