Geneva, January 26, 2005 - STMicroelectronics (NYSE: STM) reported financial results for the fourth quarter and year ended December 31, 2004.

Fourth Quarter 2004 Financial Results

Net revenues for the fourth quarter were $2,328 million, up 4.3% sequentially from the $2,231 million reported in the prior quarter, and 10.2% above the $2,113 million in last year's fourth quarter. Revenues from Application Specific Products were $1,217 million, or 52% of 2004 fourth quarter net revenues. Differentiated products revenues increased 8.8% sequentially to $1,578 million, representing 67.8% of net revenues in the fourth quarter.

Gross profit was $852 million, up about 1% sequentially from the prior quarter's $845 million and 12.1% above last year's fourth quarter gross profit of $760 million. Gross margin was 36.6%, below the prior quarter's 37.9% and above the 36.0% reported for last year's fourth quarter.

Pasquale Pistorio, President and Chief Executive Officer, commented, "Within a challenging market environment, ST's fourth quarter sequential revenue growth was 4.3% - representing the high end of our initial guidance of flat to 5% growth sequentially. This performance was largely driven by seasonal as well as stronger end-market demand, notably within wireless, data storage and automotive applications, all areas where ST has traditionally been a market leader.

"Unfortunately, the sequential revenue growth did not translate into sequential gross margin improvement. Pricing pressure continued and, from an operational standpoint, manufacturing results were impacted by reduced utilization and the performance of certain fabs. Currency reduced gross margin in the quarter by approximately 120 basis points compared to the prior period."

Research and development expenses in the fourth quarter were $402 million, 4.8% above the $384 million expensed in the prior quarter, and 13.6% higher than the $354 million reported in the comparable year-ago period. R&D costs represented 17.3% of net revenues in the 2004 fourth quarter compared to 17.2% of net revenues in the prior quarter, and 16.7% of net revenues in the year-ago quarter.

Selling, general, and administrative expenses were $245 million for the 2004 fourth quarter, 5.0% above the prior quarter's $233 million, and 7.4% above the $228 million incurred in the comparable year-ago period. SG&A costs represented 10.5% of net revenues, compared to 10.4% in the prior quarter, and 10.8% in last year's fourth quarter.

For ST, the sequential average increase in the value of the Euro versus the U.S. dollar in the 2004 fourth quarter was approximately 5%, resulting in an average exchange rate of $1.27 to 1 Euro from a third quarter average level of $1.21 to 1 Euro. The change in the exchange rate affects ST's cost of goods sold, operating costs and period end balance sheet items, including inventory. The Company noted that inventory at year-end totaled $1,344 million, with changes in currency rates accounting for approximately $80 million of the increase from $1,196 million at September 25, 2004.

Operating income was basically unchanged at $210 million on a sequential basis, or 9.0% of net revenues, in the 2004 fourth quarter. This included $18 million in impairment, restructuring charges and other related closure costs, as well as $23 million in other income. Operating income was $213 million in the prior quarter and $153 million in last year's fourth quarter.v Net income equaled $187 million in the 2004 fourth quarter, essentially flat compared to the $189 million reported in the 2004 third quarter and up significantly in comparison to 2003 fourth quarter net income of $144 million. Earnings per diluted share were $0.20 for the 2004 fourth quarter, the same as the $0.20 earned in the 2004 third quarter. In the 2003 fourth quarter, earnings per diluted share totaled $0.16.

Balance Sheet Highlights at December 31, 2004

At December 31, 2004, ST had cash and cash equivalents of $1.95 billion. Total debt was $1.958 billion; net financial debt was $8 million while shareholders' equity was $9.1 billion.

Net cash from operating activities equaled $2,342 million for the full year compared to $1,920 million in 2003. Capital expenditures were $423 million in the 2004 fourth quarter and $2,050 million for the full year. Net operating cash flow ( ) was favorable by $208 million for the full year 2004.

Full Year 2004 Results

Net revenues for the year ended December 31, 2004 were $8,760 million, an increase of 21.0% over the $7,238 million recorded in 2003. Gross profit was $3,228 million, or 36.8% of net revenues, compared to $2,566 million or 35.5% in 2003. Operating income was $683 million, or 7.8% of net revenues, compared to $334 million or 4.6% of net revenues in 2003.

Mr. Pistorio said, "ST's 21% year over year sales growth was driven primarily by wireless, digital consumer and automotive applications, which all grew faster than the company average."

"During 2004, the Company continued to focus on driving key initiatives to improve our competitive positioning within the semiconductor industry. Our marketing objectives to broaden our customer base are delivering positive results, with 31% growth among customers outside our traditional top 50. Our manufacturing restructuring plan to enhance our cost structure and competitiveness is moving ahead and we expect it to be completed by mid 2006, somewhat later than previously anticipated to accommodate qualification requirements of our customers. As previously announced, we have reorganized our product groups and enter 2005 better positioned to serve the various application requirements, and in particular the converging marketplace for communications and multimedia. And, most importantly, ST has added significant resources, over 1,000 engineers between December 2003 and December 2004, to the research and development staff in order to strengthen and enhance our product portfolio. While there is more work to be done, we made solid progress in 2004."

Net income for 2004 was $601 million, or $0.65 per diluted share. In the prior year, net income was $253 million, or $0.27 per diluted share. Before impairment, restructuring charges and other related closure costs and R&D in process, and a non-operating pre-tax charge of $39 million related to bond repurchases, net income was $435 million, or $0.46 per diluted share in the prior year.

Research and development costs for 2004 were $1,532 million, or 17.5% of net revenues, compared to $1,238 million, or 17.1% of net revenues in 2003. Selling, general and administrative expenses were $947 million, or 10.8% of net revenues in 2004, compared to $785 million, or 10.8% of net revenues in 2003.

For ST, the average exchange rate of the Euro versus the U.S. dollar for the full year 2004 was approximately $1.236 to €1, compared to $1.125 to €1 in 2003.

Outlook
Mr. Pistorio commented, "In addition to earlier-stated strategic initiatives, the Company is undertaking several near-term actions to improve financial performance. First, the Company plans to eliminate certain low volume, non-strategic product families whose return on net assets in the current environment does not meet internal targets. In particular, the Company will scale back the Access programs focused on Customer Premises Equipment (CPE) modem products. This effort will result in impairment charges of approximately $60 million in the first quarter. Second, the Company will accelerate cost reduction initiatives, including: a more selective process in dedicating capacity to new orders, with priority to higher margin products; optimization of the product and production mix in memory; consolidation of certain central function activities to control overhead; and launching an aggressive cost savings program focused on purchasing.

"With respect to the first quarter, we believe it is prudent to anticipate a decline in both revenues and gross margin due to seasonal dynamics, coupled with continued pricing pressures across many of ST's product families as a result of the industry-wide over-inventory situation, lower utilization rates, as well as the negative impact of the weaker U.S. dollar. Specifically, we expect first quarter revenues to decrease 4% to 12% in comparison to the 2004 fourth quarter and anticipate a gross margin of about 34%, plus or minus 1 percentage point. Our outlook is based upon an exchange rate of $1.32 to 1 Euro. Currency impact represents approximately 140 basis points of the anticipated sequential gross margin decline."

Recent corporate developments
Upon the proposal of our Management Board, our Supervisory Board has decided to recommend to the 2005 annual shareholders meeting the distribution of a cash dividend of $0.12 a share, equal to last year's cash dividend distribution.
