MTSN Mattson Technology, Inc.

Mattson Technology, Inc. (NASDAQ: MTSN), a leading supplier of advanced process equipment used to manufacture semiconductors, today announced results for the first quarter of 2012 ended April 1, 2012.

2012 First Quarter Financial Highlights:

• First quarter net sales of $50.5 million increased 21 percent compared with the fourth quarter of 2011.
• Net loss for the first quarter was $1.1 million, or a loss of $0.02 per share. Excluding restructuring charges of $0.7 million, first quarter net loss would have been $0.4 million, or a loss of $0.01 per share.
• The Company's balance sheet continues to be strong, with working capital of $55.8 million. Cash and cash equivalents increased $4.5 million to $37.4 million and the Company continues to carry no debt.

David L. Dutton, Mattson Technology's president and chief executive officer, commented, "The first quarter of 2012 was a solid start for Mattson Technology driven by a strong increase in sales. We approached breakeven for the quarter, and our efforts to improve gross margins and reduce operating expenses are on track to bring the Company into profitability during the year. At the same time that we are improving our financial performance, we also have extended our growth potential. Our paradigmE® etch system was released for production at a leading semiconductor's foundry facility and by a major Asian CMOS image sensor foundry. We expect that these new etch positions will incrementally add approximately 25% more annual sales opportunity to our etch business and will begin contributing to sales in the second half of 2012. Our most advanced RTP system, the Millios™, shipped to a third foundry/logic customer in the first quarter, further evidence of our emerging RTP position in foundry/logic. With our broadened product positions in foundry and NAND, plus our gross margin improvement and cost reduction programs, we expect that 2012 will result in profitable growth for Mattson Technology."

First Quarter 2012 Financial Results

First quarter 2012 net sales of $50.5 million increased $8.8 million, or 21.1 percent, compared with $41.7 million in the fourth quarter of 2011, and increased $3.5 million, or 7.3 percent, compared with $47.0 million in the first quarter of 2011. Gross margin for the first quarter of 2012 was 33.5 percent as compared to the 33.3 percent gross margin in the fourth quarter of 2011, and represents a six-point increase over the 27.4 percent gross margin in the first quarter of 2011.
