China Railways Has Seen Strong Stimulus Support; Network Build-out Continues

The renaissance of trains: High-speed and urban electric trains

China's Ministry of Railways is planning to expand the operating length of the Rail network from 86,000 km in 2009 to 120,000 km by 2020. The corresponding fixed asset investment required is USD 450bn, of which USD 125bn has been spent already.

Very high-speed rail network: The Ministry of Railways expects to increase the high speed rail operating length from 13,000 km today to 20,000 km by 2020, implying 54% growth overall.

Urban/Mass transit markets: To support the plans to urbanize 300m people by 2030, the government wants to build out the transport network in metros. This is the fastest growing segment with the operating length growing nearly 6.5x, from 960 km in 2009 to 11,700 km by 2020.

Siemens Velaro Selected by EuroStar; EUR 50K to 100K Semi Content Per Train

• 10 trains ordered for EUR 600m in total.
• 130 IGBT modules per train resulting in EUR 50,000 to 100,000 power semiconducor content per train.
• Power semiconductors represent only 0.15 to 0.2% of system cost but contribut significantly to the entire functionality.

Chip Card & Security Segment (CCS)

Revenue and Segment Result from Q1 FY08 to Q4 FY10

Sales in Q4 was driven by higher demand in certain government ID projects. Segment result doubled to EUR 12m compared with Q3.

This presentation was prepared as of November 16, 2010 and is current only as of that date.

This presentation includes forward-looking statements and assumptions about the future of Infineon"s business and the industry in which we operate. These include statements and assumptions relating to general economic conditions, future developments in the world semiconductor market, our ability to manage our costs and to achieve our growth targets, the resolution of Qimonda"s insolvency proceedings and the liabilities we may face as a result of Qimonda"s insolvency, the successful closing of the sale of our WLS business to Intel, the benefits of research and development alliances and activities, our planned levels of future investment, the introduction of new technology at our facilities, our continuing ability to offer commercially viable products, and our expected or projected future results.

These forward-looking statements are subject to a number of uncertainties, such as broader economic developments, including the sustainability of recent improvements in the market environment; trends in demand and prices for semiconductors generally and for our products in particular, as well as for the end-products, such as automobiles and consumer electronics, that incorporate our products; the success of our development efforts, both alone and with partners; the success of our efforts to introduce new production processes at our facilities; the actions of competitors; the continued availability of adequate funds; any mergers, acquisitions or dispositions we may undertake; the outcome of antitrust investigations and litigation matters; and the resolution of Qimonda"s insolvency proceedings; as well as the other factors mentioned in this presentation and those described in the "Risk Factors" section of our most recent annual report on Form 20-F on file with the U.S. Securities and Exchange Commission.

As a result, Infineon"s actual results could differ materially from those contained in or suggested by these forward-looking statements. You are cautioned not to place undue reliance on these forwardlooking statements. Infineon does not undertake any obligation to publicly update or revise any forward-looking statements in light of developments which differ from those anticipated.
