Preliminary percentage of subscription rights exercised in Infineon’s capital increase is 96.7 percent

Neubiberg, Germany – August 3, 2009 – Infineon Technologies AG reports the preliminary percentage of subscription rights exercised in the announced capital increase. With this figure currently standing at 96.7 percent, presumably at least 322 million shares will be issued to holders of subscription rights at a subscription price of Euro 2.15 per share. The gross proceeds from the capital increase will presumably amount to at least Euro 692 million.

The remaining shares, up to approximately 15 million (less any additional shareholders’ subscription declarations received in the course of the day), can be subscribed by a fund managed by Apollo Global Management LLC. This corresponds to approximately 1.4 percent of Infineon’s increased share capital totaling Euro 2.173 billion, assuming the capital increase is fully placed. Infineon expects the decision of the Apollo-managed fund no later than during the afternoon tomorrow.

Infineon expects trading in the shares issued through the exercise of subscription rights to begin on the Frankfurt Stock Exchange on Friday, August 7, 2009.
