Altera Updates Fourth Quarter Guidance Sales Expectations Move Upward

SAN JOSE, Calif.--Nov. 30, 2009-- Altera Corporation (NASDAQ: ALTR) today announced that, based on quarter-to-date results and the company's outlook for the remainder of the quarter, the company now expects sales for the fourth quarter to be 15 percent to 18 percent above third quarter levels. Previous guidance was for sales growth of 6 percent to 10 percent.

The company expects all four of its vertical markets to be up sequentially in the fourth quarter reflecting a strong new product cycle as well as improving end market trends and customer desire for appropriate inventory to support sales levels. Sales to wireline and wireless telecommunications equipment manufacturers will likely be the largest contributor to fourth quarter growth as demand for Chinese and Indian deployments has continued to improve.

The company will announce fourth quarter results after the market close on January 26, 2010.
