Infineon Simplifies Organization – Roles on Managing Board Reallocated

Munich, Germany – December 16, 2004 – Infineon Technologies AG (FSE/NYSE: IFX) is simplifying its organization effective January 1, 2005, to create shorter and faster decision paths across the entire company, a stronger customer orientation, as well as greater efficiency and flexibility. Business responsibilities on the Managing Board will be reallocated, with one Managing Board member presiding over each of the now three business groups. Mobile and wireline communications will be combined in the new Communication business group to reflect market developments. At the same time, the security and chip card activities will be integrated into the extended business group Automotive, Industrial and Multi-Market. In line with this reorganization, business units will be both aligned or founded, and therefore, overall economic responsibility will be rooted more deeply within the company. The business groups and business units will be invested with all the essential functions of a ‘company within the company’. These measures will improve the conditions for successful engagement in an increasingly dynamic and volatile global semiconductor market.

“Following a phase of strong growth over the last several years, adjusting our organization is a consistent step in building up our business groups into powerful and efficient units that can respond better and more quickly to the needs of our customers in the relevant market segments,” said Dr. Wolfgang Ziebart, Infineon’s President and CEO. “We want to liberate the entrepreneurial forces within the company. Complex matrix organizations with a functional management board are no longer appropriate to the size of the enterprise we are today.”

The schedule of responsibilities of the five-member Managing Board will be reallocated at the beginning of next year. Alongside the President and CEO and the Chief Financial Officer, the three board members Peter Bauer, Kin Wah Loh, and Dr. Andreas von Zitzewitz will assume direct entrepreneurial responsibility for one business group each.

Dr. Wolfgang Ziebart will remain as President and CEO of Infineon Technologies AG and Peter J. Fischl Chief Financial Officer and Labor Director. Dr. Andreas von Zitzewitz will also remain responsible for the central function ‘manufacturing strategy’ and Peter Bauer for central sales functions.

The previously centralized sales organization will now be dedicated to the three business groups Automotive, Industrial and Multi-Market, Communication and Memory Products. Combining and tightly intermeshing sales with development and production within the groups will deliver major benefits to customers. In future, the groups will also directly manage the strategic responsibility of the business’ direction in order to keep pace even better with rapidly changing market requirements. Distribution will continue to be operated as an independent sales channel with stronger entrepreneurial responsibility.

The Automotive, Industrial and Multi-Market business group will be headed by Peter Bauer, formerly responsible for Sales and Marketing. Dr. Reinhard Ploss will head up operative business in this group and Gerhard Henschel will be responsible for finances. Kin Wah Loh, previously President and Managing Director of Infineon Asia Pacific and appointed to the Managing Board on December 01, 2004, will be responsible for the new Communication business group. Professor Dr. Hermann Eul will be head of technology in this segment and finances will be in the hands of Peter Gruber. Dr. Andreas von Zitzewitz, essentially responsible for operations until now, will be in charge of the Memory Products business group and will be supported by Thomas Seifert as head of business units and Dr. Michael Majerus as head of finances.

Effective February 1, 2005, Tony Ng will take over the position as President and Managing Director of Infineon Asia Pacific from the former Asia head Kin Wah Loh. Trained in electrical engineering, Ng started his career at General Electric and held a number of senior positions at Siemens Semiconductor and later at Infineon. In 2002, he changed to Osram Opto Semiconductors and was there responsible for sales and marketing in the Asia Pacific region.

The Supervisory Board of Infineon Technologies AG has approved the changes.
