Mattson Technology Added to Russell 3000 Index

FREMONT, CA--(Marketwire - Jun 25, 2012) - Mattson Technology, Inc. (NASDAQ: MTSN), a leading supplier of advanced process equipment used to manufacture semiconductors, today announced it has been added to the Russell 3000 Index when Russell Investments reconstituted its comprehensive set of U.S. and global equity indexes on June 22, 2012.

"We are pleased to be added to the Russell 3000, which reflects our continued positive momentum and effort to increase shareholder value," said David Dutton, company's CEO. "We expect our inclusion will raise our profile and generate greater interest in our stock at an institutional investor level."

Annual reconstitution of Russell's U.S. indexes captures the 4,000 largest U.S. stocks as of the end of May, ranking them by total market capitalization. Membership in the Russell 3000, which remains in place for one year, means automatic inclusion in the large-cap Russell 1000 Index or small-cap Russell 2000 Index as well as the appropriate growth and value style indexes. Russell determines membership for its equity indexes primarily by objective, market-capitalization rankings and style attributes.

The Russell 3000 also serves as the U.S. component to the Russell Global Index, which Russell launched in 2007.

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies. In the institutional marketplace, an industry-leading $3.9 trillion in assets currently are benchmarked to them. The Company will hold its membership until Russell reconstitutes its indexes in June 2013.
