San Mateo, Calif. - October 21, 2009— Glu Mobile Inc. (Nasdaq: GLUU), a leading global publisher of mobile games, today announced that it ranked number 129 on Technology Fast 500™, Deloitte LLP’s ranking of 500 of the fastest growing technology, media, telecommunications, life sciences and clean technology companies in North America. Rankings are based on percentage of fiscal year revenue growth during the five-year period from 2004–2008. Glu grew 1,178 percent during this period.

Glu’s CEO, Greg Ballard, attributes this outstanding revenue growth to Glu’s focus on consistently delivering high quality games to every mobile platform and having an impressive lineup of games that surprise and delight gamers with titles that are refreshingly fun and can be played anytime, anywhere. He said, "Glu has proven that it can not only create quality games, but also stay significant and successful in a rapidly changing market."

“Technology Fast 500™ recognises innovative companies that have broken down barriers to success and defied the odds with their remarkable five-year revenue growth,” said Phil Asmundson, Vice Chairman and U.S. Technology, Media and Telecommunications leader, Deloitte LLP. "We congratulate Glu on this accomplishment."

“With its impressive five-year growth, Glu has earned its position among the fastest growing technology, media, telecommunications, life sciences and clean technology companies in North America,” said Mark Jensen, Managing Partner, Technology and Venture Capital Services, Deloitte&Touche LLP.”Deloitte is proud to honour Glu for its achievement.”

Technology Fast 500™ Selection and Qualifying Criteria

Technology Fast 500™ provides a ranking of the fastest growing technology, media, telecommunications, life sciences and clean technology companies in North America. This ranking is compiled from nominations submitted directly to the Technology Fast 500™ website, and public company database research conducted by Deloitte. Technology Fast 500™ award winners for 2009 are selected based on percentage fiscal year revenue growth during the five year period from 2004 to 2008.

In order to be eligible for Technology Fast 500™ recognition, companies must own proprietary intellectual property or proprietary technology that contributes to a significant portion of the company's operating revenues. Using other companies' technology or intellectual property in a unique way does not satisfy this requirement. Consulting companies, professional service firms, etc. are not eligible unless they have proprietary technology that contributes to a significant portion of their operating revenues.

Technology Fast 500™ award eligibility requirements also include base-year operating revenues of at least $50,000 USD or CD, and current-year operating revenues of at least $5 million USD or CD.
