Letter to External Stakeholders:

Dear Shareholder,

You may in the past 24 hours have become aware of media reports concerning the possible Insider Trading activity of two Acer employees. At Acer we place the highest value on Corporate Ethics and we can assure you that we are fully cooperating with the authorities as they carry out their investigations. However, the investigations are an individual matter and it would not be appropriate for Acer to make further comment while such investigations are on-going.

We apologize for the disruption caused by this incident. It comes at a time when we are working hard to transform Acer and we will not be deflected from this vital purpose.

Thank you for your continued support.

Stan Shih

Chairman

Acer Inc.
