SANTA CLARA, Calif., Oct 31, 2007 /PRNewswire-FirstCall via COMTEX News Network/ -- Align Technology, Inc. (Nasdaq: ALGN), the inventor of Invisalign, a proprietary method of straightening teeth without wires or brackets, has been named to Deloitte's prestigious Technology Fast 50 Program for Silicon Valley, a ranking of the fastest growing technology, media, telecommunications, and life sciences companies in the region by Deloitte & Touche USA LLP, one of the nation's leading professional services organizations. Rankings are based on the percentage revenue growth over five years from 2002-2006.

Thomas M. Prescott, Align's president and CEO, credits the Company's growth to Align's leadership and technology advantage in a large untapped market. "Our growth reflects the tremendous market opportunity for Invisalign and strong interest among consumers and dental professionals. Align is the market leader in clear aligner therapy, and we will continue to press that advantage as we strive to become the most important part of our customers' practices," said Prescott.

Align Technology's increase in revenues of 196 percent from 2002 to 2006 resulted in a #23 ranking in the Scientific & Medical Equipment, and Bio-Technology category of the Technology Fast 50 for Silicon Valley. The average increase in revenues among companies who made the Technology Fast 50 for this region was 1,455 percent.

"Deloitte's Silicon Valley Technology Fast 50 companies have shown the strength, vision and tenacity to succeed in today's very competitive technology environment," said Mark Jensen, partner and national director, Venture Capital Services, Deloitte & Touche LLP. "We applaud the successes of Align Technology and acknowledge it 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 2002 and $5,000,000 in 2006, be headquartered in Silicon Valley, and be a company that owns proprietary technology or proprietary intellectual property that contributes to a significant portion of the company's operating revenues; or devotes a significant proportion of revenues to the research and development of technology. Using other companies' technology or intellectual property in a unique way does not qualify.

Companies from the 16 regional Technology Fast 50 programs in the United States and Canada are automatically entered in Deloitte's Technology Fast 500 program, which ranks North America's top 500 fastest growing technology, media, telecommunications and life sciences companies.

About Align Technology, Inc.

Align Technology designs, manufactures and markets Invisalign, a proprietary method for treating malocclusion, or the misalignment of teeth. Invisalign corrects malocclusion using a series of clear, nearly invisible, removable appliances that gently move teeth to a desired final position. Because it does not rely on the use of metal or ceramic brackets and wires, Invisalign significantly reduces the aesthetic and other limitations associated with braces. Invisalign is appropriate for treating adults and older teens. Align Technology was founded in March 1997 and received FDA clearance to market Invisalign in 1998.
