Q3 2011 Financial Highlights

Q3 2011 Revenue and Profit In-Line with Guidance *See reconciliation to GAAP at end of presentation $ Millions Revenue increased 1% from Q2 ‘11 but declined 3% from Q3 ’10 GAAP EPS was $1.31 and non-GAAP EPS was $1.33; at high end of guidance range Gross margin was 47%, in line with guidance Non-GAAP EPS

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 Revenue & EBITA Performance by Segment Data Storage $34M Down 25% sequentially and flat versus 2010 Total Revenue: $268M LED & Solar $234M Up 7% sequentially but down 4% from Q3’10 MOCVD at $221M ($M) Q3 ‘11 Q3 ’10 Adj EBITA $72.8 $97.9 ($M) Q3 ‘11 Q3 ‘10 Adj EBITA $7.9 $9.2 See reconciliation to GAAP at end of presentation

Q3 2011 Bookings Performance by Segment Data Storage $21M Down 44% sequentially and 39% year-over-year Total Bookings: $133M LED & Solar $112M Down 59% sequentially and 54% year-over-year MOCVD $103M & MBE $9M Book to Bill = .5 to 1; Backlog $389M

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
