Geneva, July 25th, 2006 - STMicroelectronics (NYSE: STM) reported financial results for the second quarter and six months ended July 1, 2006.

Revenues, Gross Profit, and Margin Review
Net revenues for the second quarter were $2,495 million, 15.4% above the $2,162 million reported in last year’s second quarter. This year-over-year growth was driven by double-digit increases in telecom, notably wireless, computer, and the industrial market segments. Sequentially, net revenues grew 5.6% from the $2,364 million reported in the prior quarter. This sequential sales growth performance was broad based, led by the industrial market segment which increased at a double-digit rate.

Gross profit was $882 million for the 2006 second quarter, an increase of $168 million from $714 million in last year’s second quarter. Gross margin was 35.4% in the second quarter, an increase of 240 basis points from 33.0% in last year’s second quarter. On a sequential basis, gross profit increased from the first quarter level of $837 million with the gross margin unchanged at 35.4%.

Operating Expenses
Combined selling, general, & administrative and research & development expenses represented 27.0% of net revenues in the second quarter, compared to 31.4% in the year-ago quarter and 28.1% in the first quarter of 2006. R&D expenses of $408 million in the second quarter were essentially flat with the $409 million in the prior quarter while SG&A expenses were $266 million for the 2006 second quarter compared to $256 million in the first quarter of 2006.

Operating Income, Net Income, and Earnings per Share
Operating income, net income, and earnings per share all increased significantly in comparison to the year-ago period. For the 2006 second quarter, the Company reported operating income of $169 million and net income of $168 million, or $0.18 per diluted share. In the year-ago quarter, the Company reported operating income of $12 million and net income of $26 million or $0.03 per share. In the prior quarter, the Company reported operating income of $140 million and net income of $132 million or $0.14 per diluted share.

The Company posted $34 million of impairment, restructuring charges, and other related closure costs during the 2006 second quarter mainly related to workforce reduction, representing an after-tax impact of approximately $0.03 per share. In the prior quarter, restructuring-related expenses were $13 million, or $0.01 per share after-tax and $22 million, or $0.02 per share after-tax in the year-ago quarter.

In the second quarter of 2006, the effective average exchange rate for the Company was approximately $1.23 to €1, compared to $1.20 to €1 in the first 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.

President and CEO Remarks
Carlo Bozotti, President and CEO, commented, “ST delivered strong revenue and earnings improvements in the second quarter and first half of the year. Revenue in the first half of 2006 rose 14.4% versus the year-ago period, compared to preliminary industry growth estimates of about 9%, demonstrating that ST is gaining market share due to both an expanding customer base and the increasing strength of our product offerings. We will continue improving the competitiveness of our product portfolio throughout the remainder of this year, with important additional design wins in all market segments.

“In combination, our favorable revenue results, enhanced by cost-saving initiatives, enabled ST to deliver in the quarter strong growth in net income of over $140 million year over year and approximately 28% sequentially. Importantly, all product group segments’ operating margins improved sequentially and year over year. The sequential increase in operating income before restructuring, along with some expansion in asset turns thanks to disciplined capital spending, resulted in a second quarter RONA approaching 10%.

“Moreover, our second quarter key financial metrics of earnings per share before restructuring increased to $0.21 from $0.05 a year ago, while first half 2006 net operating cash flow reached $428 million. We expect continuing improvements in earnings per share as the phase-out of three fab lines is completed and other remaining cost-action benefits are realized.”

Certain costs, mainly R&D, formerly in the “Others” category, have been allocated to the segments.

Sequentially, Application Specific Product Groups revenues increased 3.8%, MPA sales increased 14.1%, and MPG sales increased 0.9%. Operating profit increased for all segments with operating income of $108 million, $87 million, and $23 million for Application Specific Product Groups, MPA, and MPG, respectively. In Flash memory, the product mix improved, reflecting double-digit sales growth of NOR products. Overall, Flash memory sales were essentially flat on a sequential basis at $401 million.

Q2 2006 Net Revenues by Market Segment
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 in the second quarter of 2006.

First Half 2006 Results
Net revenues for the first half were $4,858 million, an increase of 14.4% over the 2005 first half revenues of $4,245 million. Gross profit was $1,719 million, or 35.4% of net revenues, compared to $1,399 million or 32.9% of net revenues for the 2005 first half.

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

Outlook
Mr. Bozotti stated, “We still anticipate industry growth for 2006 in the high-single digits on a percentage basis, with continuing expansion in 2007. For ST, we expect sequential sales growth in the range between -1% and 5%, consistent with our traditional low single-digit seasonal progression in the third quarter. With the tougher currency environment, we expect gross margin to be about 36%, plus or minus 100 basis points, including the effects of approximately half a point due to a recent power blackout at an Italian plant, still under a final assessment. ”

This guidance is based on an assumed currency exchange rate for the Company of approximately $1.255 = €1 for the 2006 third quarter, which reflects current exchange rate levels combined with the impact of existing hedging contracts. This compares to the first quarter average effective rate of $1.20 = €1.
