Geneva, January 28, 2004 - STMicroelectronics (NYSE: STM) reported financial results for the fourth quarter and year ended December 31, 2003.

Fourth Quarter 2003 Financial Results
Net revenues for the fourth quarter were $2,113 million, a 17.1% sequential increase over the $1,804 million reported in the 2003 third quarter, and 18.3% above the $1,786 million of last year's fourth quarter. Revenues from differentiated products were $1,464 million or 69.3% of net revenues for the 2003 fourth quarter.

Pasquale Pistorio, President and Chief Executive Officer, "ST's 2003 fourth quarter revenue performance was stronger than anticipated, fueled by a combination of both seasonal and fundamental end market demand. We experienced solid order flows from key high growth applications within our targeted market segments, specifically wireless, automotive and audio, set-top-box, smart cards, data storage and certain industrial applications served by our high performance analog products. At the same time, we posted a 44.9% sequential increase in Flash memory product sales. Also in the fourth quarter we were successful in our expanded marketing program, selling greater numbers of multi-socket products to a broader customer base."

Gross profit was $760 million, a 20.3% sequential increase over the prior quarter's $632 million, and 15.0% above last year's fourth quarter gross profit of $661 million. Gross margin was 36.0%, up from 35.1% in the 2003 third-quarter but below the 37.0% reported in last year's fourth quarter.

Mr. Pistorio said, "The 90 basis point sequential gross margin growth was disappointing in light of the Company's strong revenue gains in the period. Several factors contributed to this, the most important of these being the continuing decline of the US dollar, the Product Group mix shift towards lower margin devices in the period, competitive pricing pressure, the effect of the power black-out in Italy in late September, and costs associated with the Company's previously-announced restructuring program. Also," Mr. Pistorio said, "ST made greater use of outsourcing to accommodate a late quarter spurt in orders."

In the 2003 fourth quarter, research and development expenses were $354 million, 16.8% above the $303 million expended in the third quarter of 2003 and 25.1% above the $283 million reported for the comparable year-ago period. R&D costs represented 16.7% of net revenues in the 2003 fourth quarter compared to 16.8% of net revenues in the 2003 third quarter, and 15.8% of net revenues in the fourth quarter of 2002.

Selling, general and administrative expenses were $228 million for the 2003 fourth quarter, 18.8% above the prior quarter's $192 million, and 24% above the $184 million incurred in the similar year-ago period. As a percentage of net revenues, however, SG&A expenses increased slightly to 10.8%, from 10.6% in the third quarter of 2003 and 10.3% in the 2002 fourth quarter.

For ST, the average sequential increase in the value of the Euro versus the U.S. dollar in the 2003 fourth quarter was approximately 5%. This particularly affected ST's reported R&D and SG&A costs, which are primarily Euro-denominated. Additionally, R&D expenses rose in the 2003 fourth quarter as a result of the acceleration of certain of our strategic programs and $5 million in in-process R&D related to the Synad acquisition. SG&A costs increased as a consequence of certain quarter-specific expenses as well as accelerated marketing programs.

Operating income was $153 million which included $12 million in impairment, restructuring charges and other related closure costs associated with the restructuring plan and related manufacturing initiatives announced in conjunction with the release of the Company's 2003 third quarter earnings. This compares to an operating loss of $64 million incurred in the prior quarter, which included impairment, restructuring charges and other related closure costs of $193 million, and operating income of $209 million in last year's fourth quarter.

The Company did not incur a tax expense in the 2003 fourth quarter because of tax benefits resulting from restructuring charges taken in higher tax rate jurisdictions, which resulted in favorable year-end adjustments to deferred tax liability computations and to tax provisions.

Net income equaled $144 million for the 2003 fourth quarter, including impairment and restructuring charges, compared to a net loss of $49 million reported in the prior quarter, which included aftertax impairment, restructuring charges and other related closure costs of $129 million, and a non-operating charge of $21 million related to bond repurchases. Net income was $161 million in last year's fourth quarter. Earnings per diluted share were $0.16 for the 2003 fourth quarter, compared to a $0.06 loss per diluted share in the prior quarter, which included the above-mentioned impairment, restructuring charges and other related closure costs, and the non-operating charge related to bond repurchases, which in the aggregate amounted to $0.17 per diluted share. Earnings per diluted share in the 2002 fourth quarter were $0.18.

Commenting on 2003 fourth quarter performance, Mr. Pistorio said, "ST maintained its leadership positions in key targeted markets and applications and successfully completed the first phase of its marketing program to accelerate top-line growth through offering a broad range of products to an expanded customer base. Profitability did not keep pace with revenue growth due to a number of factors described above, but was basically in line with expectations, especially given the currency situation we are faced with. And, we are confident that the significant R&D expenditures and marketing costs incurred in the 2003 fourth quarter will provide positive returns as 2004 unfolds."

Balance Sheet Highlights at December 31, 2003
At December 31, 2003, ST had cash, cash equivalents and marketable securities of $3 billion. Total debt was $3.10 billion, of which $2.94 billion was long-term; shareholders' equity was $8.10 billion. The net debt to shareholders' equity ratio was 0.012.

Net cash from operating activities in the fourth quarter was $778 million and reached $1,920 million for 2003. Capital expenditures were $406 million in the 2003 fourth quarter, compared to $261 million in the third quarter of 2003, and $225 million in the year-ago fourth quarter. For the full year 2003, capital expenditures totaled $1,221 million compared to $995 million in the prior year.

Full Year 2003 Results
Net revenues for the year ended December 31, 2003 were $7,238 million, up 14.6% from the $6,318 million reported in 2002. Gross profit was $2,566 million, or 35.5% of net revenues. Operating income was $334 million, or 4.6% of net revenues. Excluding impairment, restructuring charges and other related closure costs and R&D in process, operating income was $544 million, or 7.5% of net revenues.

Research and development costs for 2003 were $1,238 million, or 17.1% of net revenues, compared to $1,022 million in 2002, or 16.2% of net revenues. Selling, general and administrative expenses were $785 million, or 10.8% of net revenues, compared to $648 million, or 10.3% of net revenues in 2002.

Reviewing 2003 results, Mr. Pistorio noted, "ST produced annual revenues in 2003 of close to $7.24 billion driven primarily by unit demand on the part of our strategic customer alliances, as well as a growing group of key customers. The Company remained solidly profitable for the year, as it has during the severe industry downturns of 2001 and 2002, but profitability levels were significantly limited by the industry-wide overcapacity and the resulting pricing pressures that persisted throughout most of 2003. Also, specific to ST, rapid currency fluctuations affected our reported operating expenses for 2003, thus negatively impacting our bottom-line year-over-year comparisons," Mr. Pistorio said.

"This situation, however," Mr. Pistorio added, "did not prevent ST from improving its financial position, which we further strengthened through the debt restructuring executed during the year. Additionally, we are pleased to report that operating cash flow* for the year was $477 million, and $665 million before acquisitions," Mr. Pistorio noted.

Corporate Developments
The Company will hold its Annual General Meeting of Shareholders on April 23, 2004 in Amsterdam, The Netherlands.

Outlook
Looking ahead, Mr. Pistorio commented, "ST has entered 2004 with a solid order backlog and strong fundamental demand for products serving key high-growth applications. Thus, we anticipate a muted seasonal effect in the first quarter, enabling ST to report revenues for the period of at least $2 billion and possibly even flat with the over $2.1 billion of the 2003 fourth quarter. This would represent growth of approximately 24% - 31% over last year's first quarter. Such performance would put us in an excellent position upon which to build momentum as the industry recovery continues," he noted, "underscoring our determination to grow faster than the markets we serve."

Mr. Pistorio continued, "We expect that there will be a certain lag time, however, before our gross margin reflects the benefits of our recently-launched restructuring program and other initiatives we have taken. As a result, and based upon current currency levels, we expect our first quarter 2004 gross margin to be approximately 35%," he said.

"It is our expectation that ST's gross margin will progressively improve throughout 2004, accelerating in the second half of the year. The drivers will be several factors including production transfer to Singapore 6"; the ramp up of our leading-edge fabs in Rousset and Singapore; and volume production in 130 nanometers and below for several products, including Flash memories," Mr. Pistorio said.

"Also benefiting ST's gross margin in 2004, as well as our overall performance, will be new product introductions and the better pricing environment that is forecasted to characterize the industry's growth in 2004," Mr. Pistorio concluded.

Recent Developments

• On December 18, 2003, ST announced the acquisition of the wireless-LAN company Synad Technologies Ltd, a fast-growing UK startup that is one of the few able to deliver a full dual-band multistandard solution. Further strengthening ST's broadband-access portfolio, the Company will offer Synad's very advanced solutions for network-card and access-point applications, in addition to bundling these chips with ST's existing broadband-access solutions.

Corporate Social Responsibility

ST continued its commitment to corporate social responsibility in 2003.

Highlights included our recognition in the area of environmental protection, where we were awarded the Best Industrial Renewable Energy Partnership as part of the European Commission's Campaign for take-off for Renewable Energy Awards 2003.

Additionally; we accelerated our program to help bridge the Digital Divide through offering computer literacy courses in communities in which we operate. This program aims to reach one million people within a decade.
