Business Update and Outlook John R. Peeler, CEO

Q3 2011 Business Highlights LED & Solar: MaxBright™ widely accepted by tier one customers around the world – represented nearly half of MOCVD revenue China Training Center has trained >200 engineers since May opening Taiwan Tech Center fully staffed and collaborating with customers on process development Data Storage: HDD roadmap is placing more emphasis on improving yield and reducing costs We are engaged in customer programs utilizing Veeco’s new CVD, PVD and DLC technologies

Q3 2011 Bookings Were Weak Across the Board Slower than expected growth in worldwide LED TV sales LED factory utilization rates in Asia remain low (50-70%) Decreased business activity in China resulting from credit tightening and funding availability Data Storage customers delayed capex plans due to pending consolidations and weak PC sales Negative global macro-economic data points caused customers to slow or cut their capacity expansion plans We currently expect that MOCVD orders will remain depressed for a few quarters
