Mattson Technology Provides Preliminary Financial Information for Q42010

FREMONT, CA -- (MARKET WIRE) -- 01/04/11 -- Mattson Technology, Inc. MTSN, a leading supplier of advanced process equipment used to manufacture semiconductors, today provided preliminary financial information for the Company's fourth quarter ended December 31, 2010. The Company expects to report results for the fourth quarter and the completed fiscal year in early February 2011. Due to a delay in the shipment of several tools scheduled for DRAM customers, net revenue for the fourth quarter is expected to be approximately $41 million. The Company's fourth quarter guidance, established October 20, 2010, was $46 million to $50 million. Third quarter net revenue was $39.8 million. The delay in tools sold to DRAM customers caused a change in the mixture of tool types shipped. The Company therefore expects gross margin for the fourth quarter to be significantly below the previously announced range of 36 percent to 39 percent. Similarly, net loss per share is expected to be significantly greater than the previously announced range of ($0.04) to $0.00. Cash, cash equivalents, short-term investments and restricted cash for the fourth quarter is expected to be approximately $24 million. This compares with previous guidance of a range of $30 million to $33 million. The decrease in cash occurred because the shipment delays occurred late in the quarter, and cash had already been used to purchase inventory and complete the tools.
