Simulations Plus to Be Named One of Los Angeles' Fastest Growing Technology Companies in Deloitte Technology Fast 50 Program.

LANCASTER, Calif. -- Simulations Plus, Inc. (AMEX:SLP) will be named to Deloitte's prestigious Technology Fast 50 program for Los Angeles, a ranking of the 50 fastest-growing technology companies in the area by Deloitte & Touche LLP, one of the nation's leading professional services firms. Scheduled to be announced September 21, Technology Fast 50 rankings are based on the percentage of growth in fiscal year revenues over five years, from 1999-2003.

Simulations Plus' CEO, Walt Woltosz, credits the rapid adoption of the company's software for pharmaceutical research with the company's fast growth over the past five years. He said, "We are honored to be selected once again for the Los Angeles Technology Fast 50. We thank Deloitte & Touche for recognizing our success and for sponsoring this way of providing recognition to companies that are changing our world through technology."

"The Deloitte Los Angeles Technology Fast 50 companies have shown the strength, vision and temerity to succeed despite a very challenging technology environment," said Tim Lovoy, Deloitte partner, Technology, Media & Telecommunications practice, Los Angeles. "We applaud the successes of Simulations Plus and acknowledge their place as one of the very few to accomplish such a fast growth rate over the past five years."

To qualify for the Technology Fast 50, companies must have had operating revenues of at least $50,000 in 1999 and $1,000,000 in 2003, must be public or private companies headquartered in North America, and be a "technology company" defined as owning proprietary technology that contributes to a significant portion of the company's operating revenues (using other companies' technology in a unique way does not qualify); and/or devoting a significant proportion of revenues to research and development of technology.

Winners of the 19 regional Technology Fast 50 programs in the United States and Canada are automatically entered in the Deloitte Technology Fast 500 program, which ranks North America's top 500 fastest growing technology companies.
