TSMC’s Fourth-Quarter Business Guidance Revised

Hsin-Chu, Taiwan, R.O.C., December 1, 2008 — TSMC today announced that fourth-quarter business will be below the company’s previous guidance given on October 30, 2008 due to a reduction of wafer shipment resulting from continuing weakness in global economic conditions. The company now expects fourth-quarter revenue to be between NT$63 billion and NT$65 billion, lower than the previous expectation of between NT$69 billion and NT$71 billion.

The company’s expectation for fourth-quarter gross profit margin is now between 30% and 32%, and operating profit margin is between 17% and 19%, lower than the previous guidance by 4 percentage points each.

The company is expected to release its fourth-quarter results on January 22, 2009.
