•		Revenues in the Communication Solutions segment are expected to grow significantly. Segment EBIT excluding a low double-digit million Euro write-down of acquired in-process research & development relating to the mobile phone business acquired from LSI is expected to be about break-even, including break-even EBIT in the wireless business.

Outlook for Infineon excluding Qimonda for first quarter of the 2008 fiscal year

For the first quarter of the 2008 fiscal year, Infineon expects revenues for its segments excluding Qimonda, and including the mobile phone business recently acquired from LSI, to be about flat compared to the last quarter. The company anticipates EBIT for its businesses excluding Qimonda and excluding charges to decrease from last quarter’s level. In the first quarter, Infineon expects to book a low double-digit million Euro gain from the sale of a stake in its high-power bipolar activities. Antitrust approval for this transaction is still pending. In addition, Infineon expects to include a low double-digit million Euro write-down of acquired in-process research & development relating to the mobile phone business recently acquired from LSI.

Additional details concerning the outlook can be found in the segments’ sections below.

“We have improved EBIT and EBIT margin for Infineon excluding Qimonda and excluding charges throughout the 2007 fiscal year. EBIT in the Communication Solutions segment improved each quarter as we executed on our turn-around. The Automotive, Industrial & Multimarket segment also posted improved EBIT in each quarter of the 2007 fiscal year, with record revenues and EBIT in the fourth quarter”, said Dr. Wolfgang Ziebart, President and CEO of Infineon Technologies AG. “We expect to improve EBIT excluding charges for Infineon excluding Qimonda significantly in the 2008 fiscal year compared to the previous year and to make a significant step towards our fiscal 2009 goal of ten percent EBIT margin. We expect to meet our turn-around goal in wireless with break-even EBIT in the current quarter.

We also anticipate that our recent acquisitions of the DSL business of Texas Instruments and the mobile phone business of LSI will contribute to our growth.”

Segments’ fourth quarter performance and outlook

Automotive, Industrial & Multimarket (AIM)

		Bars: Revenues in millions of Euro; Line: Reported EBIT margin in percent with EBIT in millions of Euro.

In the fourth quarter of the 2007 fiscal year, the Automotive, Industrial & Multimarket segment reported record revenues of Euro 814 million, representing an eight percent increase compared to the prior quarter. Segment EBIT increased to Euro 98 million from Euro 81 million in the prior quarter. Third quarter segment EBIT included a gain of Euro 17 million related to the sale of the company’s POF business.

Revenues and EBIT in the automotive business remained broadly unchanged from the third quarter, as expected. The industrial & multimarket business increased revenues and EBIT significantly, mainly due to seasonally higher demand in the consumer, computing, and telecom markets. The results of the security & ASICs business were better than anticipated, mainly due to high demand in the chip card and security business.

Automotive, Industrial & Multimarket’s outlook for first quarter of the 2008 fiscal year

In the first quarter of the 2008 fiscal year, Infineon expects the revenues of its Automotive, Industrial & Multimarket segment to decline by a high single-digit percentage compared to the prior quarter, mainly due to the usual seasonal pattern, the weak U.S. dollar, the deconsolidation of the high-power bipolar business, and to a lesser extent annual price reductions for major customers. Segment EBIT prior to inclusion of a low double-digit million Euro gain from the sale of a stake in the high-power bipolar activities is expected to follow the revenue decline. Revenues in the segment’s automotive business are expected to remain broadly unchanged from the previous quarter despite annual price reductions for major customers.

Revenues in the industrial & multimarket business are anticipated to decline due to seasonal weakness in the consumer, computing and telecom markets, the weak US dollar, and the deconsolidation of the high-power bipolar business. Results in the security & ASICs business are anticipated to decrease as some normalization in the chip card and security business is to be expected after the exceptionally high demand levels of the prior quarter.

Communication Solutions (COM)

		Bars: Revenues in millions of Euro; Line: Reported EBIT margin in percent with EBIT in millions of Euro.

In the fourth quarter of the 2007 fiscal year, revenues in the Communication Solutions segment were Euro 318 million, a 23 percent increase compared to the prior quarter. This included a high-teens million Euro contribution from the DSL CPE activities acquired from Texas Instruments (TI). Segment EBIT for the fourth quarter improved to negative Euro 16 million, compared to negative Euro 34 million in the third quarter.

In the wireless business, revenues increased strongly, as expected, driven mainly by a further significant increase in mobile phone platform shipments. Excluding the acquired DSL business, revenues in the broadband business increased slightly compared to the prior quarter.

Communication Solutions’ outlook for the first quarter of the 2008 fiscal year

Revenues in the Communication Solutions segment are expected to grow significantly in the first quarter of the 2008 fiscal year compared to the prior quarter. This is expected to be driven by the full-quarter inclusion of the DSL CPE business acquired from TI, by the consolidation of the mobile phone business recently acquired from LSI, and by continued growth in shipments of mobile phone platform solutions. Segment EBIT as well as EBIT for the wireless business are anticipated to be about break-even prior to inclusion of a low double-digit million Euro charge for the write-down of acquired in-process research & development in connection with the acquisition of the mobile phone business of LSI, which Infineon expects to book in the first quarter of the 2008 fiscal year.

Qimonda

		Bars: Revenues in millions of Euro; Line: Reported EBIT margin in percent with EBIT in millions of Euro *) EBIT reported net of minority interests.

In the fourth quarter of the 2007 fiscal year, Qimonda reported revenues of Euro 711 million, a decline of four percent from Euro 740 million in the third quarter. Fourth quarter EBIT was negative Euro 216 million compared to an EBIT of negative Euro 293 million in the third quarter. Minority interests, calculated from Qimonda’s fourth quarter net loss, were Euro 42 million. Infineon’s ownership in Qimonda as of September 30, 2007 was 77.5 percent, after Infineon sold 28.75 million Qimonda shares in the fourth quarter.

Qimonda’s outlook for the first quarter of the 2008 fiscal year

In the first quarter of the 2008 fiscal year, Qimonda expects its bit production to grow approximately 5 percent quarter over quarter, mainly based on productivity improvements from the ongoing conversion to 80 nanometer and 75 nanometer technologies, and including the effects of reducing 200 millimeter capacities.

EBIT

The Company defines EBIT as earnings (loss) before interest and taxes. The Company’s management uses EBIT, among other measures, to establish budgets and operational goals, to manage the Company’s business and to evaluate its performance. The Company reports EBIT information because it believes that it provides investors with meaningful information about the operating performance of the Company and especially about the performance of its separate operating segments. Because many operating decisions, such as allocations of resources to individual projects, are made on a basis for which the effects of financing the overall business and of taxation are of marginal relevance, management finds a metric that excludes the effects of interest on financing and tax expense useful. In addition, in measuring operating performance, particularly for the purpose of making internal decisions, such as those relating to personnel matters, it is useful for management to consider a measure that excludes items over which the individuals being evaluated have minimal control, such as enterprise-level taxation and financing.

Gross and Net Cash Position

Infineon defines gross cash position as cash and cash equivalents and marketable securities, and net cash position as gross cash position less short and long-term debt. Since Infineon holds a substantial portion of its available monetary resources in the form of readily marketable securities, which for U.S. GAAP purposes are not considered to be “cash”, it reports its gross and net cash positions to provide investors with an understanding of the Company’s overall liquidity. The gross and net cash position is determined as follows from the condensed consolidated balance sheets, without adjustment to the U.S. GAAP amounts presented:

Free Cash Flow

Infineon defines free cash flow as cash from operating and investing activities excluding purchases or sales of marketable securities. Since Infineon holds a substantial portion of its available monetary resources in the form of readily marketable securities, and operates in a capital intensive industry, it reports free cash flow to provide investors with a measure that can be used to evaluate changes in liquidity after taking capital expenditures into account. Free cash flow is not intended to represent the residual cash flow available for discretionary expenditures, since debt service requirements or other non-discretionary expenditures are not deducted. The free cash flow is determined as follows from the condensed consolidated cash flow statements, without adjustment to the U.S. GAAP amounts presented:

Infineon business highlights for the fourth quarter of the 2007 fiscal year

•

AIM: With growth rates estimated at approximately 10 percent within the next five years, safety applications in automotive electronics are expected to be the fastest growing. Various system manufacturers have opted in favor of using sensors to monitor tire pressure and microcontrollers from the recently introduced XC2300 family for electrical steering and airbag systems. Infineon has already been able to claim the Number 1 position for sensors for tire pressure monitoring systems (TPMS), ABS and side airbags and, thanks to new design-wins, will continue to expand this lead.

Energy efficiency

•		AIM: Infineon was able to win new customers for industrial microcontrollers for electronic drive control systems and obtained new orders from the existing customer base, which led to a growth in sales of 16-bit flash microcontrollers of approximately 50 percent in fiscal 2007. With the introduction of the 8-bit microcontroller family, the company has now also addressed the market for electric bicycles. Within a very short time, Infineon has been able to claim an international market share in this field of approximately ten percent. In China, for example, some 18.5 million e-bikes will be produced in 2007; this market is expected to grow at a rate of around 25 percent a year.
•		AIM: The business with chips that are used in fluorescent lamp ballasts is still increasing strongly, particularly due to the expansion of the customer base in the lighting technology sector. Infineon is currently supplying the five largest manufacturers in the lighting technology sector.
•		AIM: With the licensing of a specific package technology used in power conversion, Infineon was able to further consolidate its leading position in the OptiMOS 2 and OptiMOS 3 power semiconductor families. OptiMOS 2 samples deploying this package technology are expected to be available starting early 2008. The package technology is designed for use in AC-DC and DC-DC power conversion applications in computers, notebooks, telecommunications and consumer electronics devices.

Communications

•		COM: Infineon again increased mobile phone platform shipments significantly, driven by strong demand from several major customers for its entry-level single-chip solution for ultra-low cost mobile phones and EDGE platform.
•		COM: The company announced the acquisition of LSI’s Mobility Products Group, which will strengthen Infineon’s position with important mobile phone customers, especially Samsung, and add highly qualified experts to the Infineon team.
•		COM: The company further expanded its wireless customer base with the development of a 3G RF transceiver for Motorola based on Infineon’s SMARTi UE.

•

COM: Infineon was presented the InfoVision Award from the International Engineering Consortium (IEC) and once more awarded for technology leadership. Its integrated AMAZON-SE ADSL2/ 2+ system-on-a-chip (SoC) was selected as the winner in the “Enabling Silicon and Component-Level Technologies” category for its robust, high-performance solution.

Security

•		AIM: Infineon is the Number 1 chip supplier in the chip card industry for the tenth consecutive year and also holds a leading position in the growth markets for contactless chip cards, identification and pay cards.
•		AIM: Further countries selected Infineon security chips for their electronic passports. In 2007, 40 countries around the world will issue approximately 70 million such passports and in 2008 some 15 nations in Eastern Europe, South America and Asia will add to that number. Approximately 35 percent of all the electronic passports issued contain an Infineon chip.
•		AIM: Customer interest is very high in the recently introduced SLE 76 family of security controllers, which have been specially developed for use in SIM cards in the growing high-volume segment with a memory size of 64 to 256 KB.
