Braun, Veeco's Chairman and Chief Executive Officer, commented, "Veeco's fourth quarter orders, revenues and EBITA improved both sequentially and year-over-year. Order strength reflected a broad industry upturn across all of our markets and in all geographic regions. Capacity and technology drivers were evident in semiconductor, data storage, wireless, compound semiconductor and scientific research. Fourth quarter orders of $96.8 million (up 51% sequentially) were Veeco's strongest overall orders in ten quarters. Fourth quarter revenue of $76.9 million was up 22% sequentially." "The November 2003 acquisitions of TurboDisc MOCVD and Advanced Imaging Inc.'s precision lapping technologies allow us to significantly broaden our product and technology offerings to Veeco's core markets in 2004," commented Mr. Braun. Mr. Braun commented on Veeco's full year 2003, adding, "Overall 2003 was a challenging year for the equipment industry and for our customers. Veeco's 2003 sales of $279.3 million were down 7% from 2002, while orders of $297.6 were up a modest 3%. Significant 2003 focus on cost reduction and profitability resulted in improved gross margins (up 2.2 points) to 46.0% (exclusive of purchase accounting adjustments), and 2003 EBITA (earnings excluding certain charges before interest, income taxes and amortization) was $13.0 million, up from $1.3 million in 2002 despite the decrease in revenue. Veeco also generated $21.8 million of cash from operations during 2003 and our balance sheet remains strong with $106.8 million in cash after the completion of acquisitions."
