ALTERA UPDATES THIRD QUARTER REVENUE GUIDANCE

San Jose, Calif., September 7, 2010—Altera Corporation (NASDAQ: ALTR) today announced that, based on quarter-to-date results and the company’s outlook for the remainder of the quarter, third quarter revenue is now expected to be 10 to 14 percent above second quarter levels. The company’s prior guidance was for sequential growth of 4 to 8 percent.

Growth continues to be broad. It is likely that all four of the company’s vertical markets will show sequential growth. The telecom and wireless vertical market is on track to be the fastest growing portion of the business, driven in large part by 3G wireless deployments and needs for additional wireless backhaul capacity.

The company will announce third quarter results after the market close on October 19, 2010.
