Munich, Germany – January 24, 2005 – In the first quarter of financial year 2005, Infineon Technologies AG (FSE/NYSE:IFX) reported a sequential revenues decrease in each of its business segments. Sales volumes in the three logic segments declined mainly due to lower demand driven by inventory corrections by customers. Although bit production increased slightly in the Memory Products segment, overall sales volumes declined. The segment has increased inventory levels back to normal levels to serve customers more efficiently and flexibly in the future.

Excluding the impact of non-recurring license income of Euro 118 million resulting from the settlement with ProMOS in the first quarter and the impact of impairment and antitrust related charges of Euro 132 million in the prior quarter, EBIT declined in all segments except the Wireline Communications segment. The company’s comparable EBIT decrease was primarily driven by lower sales volumes, and lower fab utilization

in the Secure Mobile Solutions and Automotive & Industrial segments. Results were also negatively impacted by the decline of the US dollar.

“As anticipated in our outlook from last quarter, we have seen a slowdown in most of our application segments, a further clear market weakening and lower customer demand during the first quarter,” said Dr. Wolfgang Ziebart, CEO and President of Infineon Technologies AG. “We have thus taken necessary measures to adjust invetory levels, which negatively impacted our first quarter’s results.”

Employee Data
As of December 31, 2004, Infineon had approximately 36,000 employees worldwide, including approximately 7,300 engaged in Research and Development.

Outlook for the second quarter of financial year 2005
Based on the ordering behavior of Infineon’s customers and forecasts of market research institutes, Infineon anticipates a continued slowdown in demand in the overall worldwide semiconductor market during the second quarter of financial year 2005. Due to seasonal effects, pricing pressure in all of the company’s application segments, and a further decline in demand as customers continue to adjust inventory, the company expects revenues and earnings in the current quarter to decline further.

“While many of the measures we have taken to improve our competitiveness are a real challenge for our company in the short term, they are necessary in order to secure our mid and long term future,” commented Dr. Ziebart. “We have further tightened the control on cost, investment and working capital and have identified fixed cost reductions of Euro 200 million for the 2005 financial year compared to the original plan.”

Business groups’ 2005 first quarter performance and outlook
Effective January 1, 2005, Infineon has simplified its organization to create shorter and faster decision paths across the entire company, a stronger customer orientation, as well as greater efficiency and flexibility. The Mobile and Wireline Communication segments have been combined in the new Communication business group to reflect market developments. At the same time, the security and chip card activities have been integrated into the extended business group Automotive, Industrial and Multi-Market. Infineon will report its financial position and results of operations under this new organizational structure starting with the second quarter of the 2005 financial year.

Automotive & Industrial

The sequential revenue decrease resulted primarily from reduced sales volumes due to softer demand. Therefore, the segment had to correct inventories and saw the same behavior at customers in both the Automotive and the Industrial businesses. The sequential EBIT decline was a consequence of lower sales volumes and increased idle capacity costs. As the company actively reduced inventory levels, production and fab utilization decreased more strongly than sales volumes, resulting in margin pressure.

Automotive & Industrial’s outlook for the second quarter of financial year 2005
In the automotive industry, Infineon sees no major market changes in the worldwide demand for semiconductors. Due to seasonal effects, the company expects a weaker development in its Industrial segment. Since most of the segment’s necessary inventory reductions have been completed, Infineon expects no further deterioration in fab utilization in the Automotive & Industrial segment. Overall, Infineon anticipates revenues in the second quarter of financial year 2005 to increase slightly. However, earnings are expected to decrease slightly due to the annual price reductions in the automotive business.

Wireline Communications

- 4 -

The sequential revenue decline was mainly driven by lower sales of access products due to inventory corrections in the supply chain, especially in Asia. The EBIT loss decreased sequentially, primarily due to continuing cost reductions and the non-recurrence of impairment charges in the fourth quarter of financial year 2004.

On January 11, 2005, the Infineon Management Board decided to terminate the Amended and Restated Master Sale and Purchase Agreement with Finisar Corporation dated October 11, 2004, due to circumstances beyond Infineon’s control. The termination of the agreement with Finisar Corporation and the related planned restructuring of the Fiber Optics business did not impact the results of operations and financial position of the segment in the first quarter of financial year 2005.

Wireline Communications’ outlook for the second quarter of financial year 2005
Despite ongoing pricing pressure, slightly decreasing inventory levels at customers, and declining demand in traditional telecom, Infineon expects revenues and operating losses in the second quarter of financial year 2005 to remain stable. In addition, the company is currently in the process of evaluating the impact that the termination of the agreement with Finisar Corporation and the related planned restructuring of the Fiber Optics business will have on the financial position and results of operations of the company in future periods.

Secure Mobile Solutions

While the sequential revenue decline was mainly driven by reduced volumes resulting from inventory corrections at customers, the sequential EBIT decrease was primarily caused by increased idle capacity costs due to lower manufacturing utilization, reduced sales volumes, and increased pricing pressure.

Secure Mobile Solutions’ outlook for the second quarter of financial year 2005
Due to the usual seasonal slowdown of the mobile phone market in the first quarter of the calendar year in combination with lower orders compared to the first quarter of last financial year, Infineon anticipates a continuing weak development of sales volumes in the second quarter of financial year 2005. Because of the anticipated continuing pricing pressure and lower sales volumes, the company expects a further decrease in revenues exceeding the decline of the prior quarter. The company intends to reduce inventories during the second quarter by further reducing production volumes. Average capacity utilization will continue to decline and is anticipated to result in a significantly stronger decline of EBIT margin than in the previous quarter.

Memory Products

In addition to the effects of the sharp decline of the US dollar, the sequential revenue decrease resulted primarily from lower sales volumes compared to the previous quarter, with the segment’s inventory levels increasing as anticipated. Revenues and EBIT included non-recurring license income of Euro 118 million resulting from the settlement with ProMOS. EBIT of the previous quarter included an accrual of Euro 18 million in connection with DRAM antitrust investigations. Excluding these amounts, EBIT declined sequentially, primarily due to the sequential revenue decrease and partly due to the weaker US dollar.

During December of 2004, Saifun Semiconductors and Infineon modified their cooperation agreement. As a consequence, Infineon acquired Saifun’s 30 percent share in the Infineon Technologies Flash joint venture and was granted a license for the use of Saifun NROM® technology. Infineon has sole ownership and responsibility for the business and will start to account for its entire financial results effective January 1, 2005.

Memory Products’ outlook for the second quarter of financial year 2005
For the second quarter of financial year 2005, Infineon expects a seasonal reduction in DRAM prices. Bit production is expected to increase based on additional volumes from the Inotera joint venture. In addition, Infineon anticipates an increase in the number of chips sourced from its foundry partners. The company will continue to focus on the reduction of cost per produced bit and the extension of its product portfolio with higher margin products.

Other Operating Segments

The significant EBIT improvement in the first quarter of financial year 2005 compared to the previous quarter was mainly due to impairment charges for the company’s venture capital activities included in the fourth quarter of financial year 2004 that did not recur in the first quarter of financial year 2005.

To focus on the core business, in the first quarter of financial year 2005 Infineon agreed to sell its venture capital activities to Cipio Partners, a leading venture capital company in the German secondary direct market. The transaction is expected to close during the second quarter.

Corporate and Reconciliation
