Infineon at a Glance

Power Semiconductors and Manufacturing

Results and Outlook

Every Electricity Conversion Step Requires Infineon Components

Power Semiconductors Must Meet Challenging Application Requirements

CMOS versus Power Differences in Focus and Concept

Gains in Power Density Require Improved Device Characteristics All the Time

Increase in Power Density Goes Hand-in-Hand with Higher Junction Temperatures

Infineon Is The IGBT Innovation Leader

CoolMOS™ Is Break-Through High-Voltage MOSFET

• Principle of charge compensation allows drastic reduction of losses compared to traditional device concepts.
• Core know-how: structured epitaxy and thin wafer technology.
• Usable today from 500V to 900V.

Adaption of product lines and targeted development to fit a broad variety of customer requirements

Infineon Further Advances Performance Through Innovations in Modules

Worldwide Front-End Production Sites

Worldwide Back-End Production Sites

Existing Fab Landscape Sufficient to Roughly Triple Present Capacity

Front-End capacity bridge for power semiconductors

* Assuming Kulim 2 (300 mm).

Front-End and Back-End Outsourcing Strategy

Front-End outsourcing share

Status:

For nodes ≥ 90 nm foundries are mainly used to optimize capex and for flexibility.

Outlook:

Share at foundries will increase in the next five years driven by the ramp of eFlash technologies in 90 nm, 65 nm and 40 nm.

Back-End outsourcing share

Status:

Outsourcing primarily on low-power devices and complex CMOS.

Outlook:

Assembly and test outsourcing will continue to expand with Infineon's growth in the areas of power and CMOS.

Investments in FY 2013 to Be Reduced Significantly

Infineon at a Glance

Power Semiconductors and Manufacturing

Results and Outlook

Lower Revenue And Segment Result Due To Market Weakness

Gross Margins Will Improve As Utilization Increases

Capacity in place today for annualized run rate of EUR ~4.5bn.

• Utilization rate in Q1 FY13 at ~75%.
• Incremental gross profit increase of €0.75 for each €1.00 revenue increase.

OpEx In-line With Target Operating Model

R&D and SG&A resources are in place to fulfill EUR ~4.5bn annual run rate.

OpEx growth to be limited to inflation and performance-based payments in FY13 and FY14.

Profitability Determined Mainly by Utilization Levels

Guidance for Q2 FY13 and FY 2013

Outlook Q2 FY13* (compared to Q1 FY13)

Outlook FY 2013* (compared to FY 2012)

Revenue

Mid single digit percentage increase. Mid-to-high single digit percentage decline.

Segment Result / Margin

Segment Result slightly up in absolute terms.

Segment Result Margin in the mid-to-high single digits.

Investments in FY 2013 About EUR 400m.

D&A in FY 2013 About EUR 470m.

* This outlook is based on an assumed Euro/US Dollar exchange rate of 1.30.
