Santa Clara, Calif. - July 9, 2002 - Align Technology, Inc. (Nasdaq: ALGN), today announced a plan to streamline worldwide operations and reduce operating losses. As part of this new strategy, Align will eliminate costly redundancy in its manufacturing network and implement a more disciplined framework for international expansion, including resizing marketing efforts in regions where investment was substantially outpacing growth.

The plan will enable the Company to refocus on profitability without sacrificing customer programs and key corporate priorities. Specific reforms in the new strategy include:

• Closing of manufacturing and call center facilities in Pakistan and the United Arab Emirates and transitioning those operations to the United States and Costa Rica.
  
• Resizing of international structure and spending, and a more measured approach to expansion in Europe, Latin America and Asia-Pacific.
  
• A reduction in across-the-board operating costs and a reduction of approximately thirty-five percent of worldwide staff, including ten percent of the workforce at Align's Santa Clara headquarters.

Tom Prescott, Align president and chief executive officer, summarized the benefits of the new plan, saying, "These actions give us the platform to build a sustainable business, and position us to access the enormous potential of the markets our products address--in the U.S. and around the world."

The Company estimated that these broad strategic changes would result in one-time charges and costs of between $7 million and $9 million, to be spread largely over the third and fourth quarters of 2002. Invisalign product sales for the second quarter ended June 30, 2002 will come in at approximately $16.2 to $16.7 million, a greater than ten percent increase over the first quarter of 2002. Overall revenues for the second quarter of 2002 will be down slightly due to substantially lower training revenue, compared to the first quarter of 2002, as a result of the Company's transition from its former dental distributor. The Company expects revenue to grow at between ten and fifteen percent each quarter over the next two quarters and between five and ten percent each quarter in 2003 as the new strategy unfolds. Total revenues for the years 2002 and 2003 are expected to be $73-76 million and $100-105 million, respectively. The Company expects to reach positive cash flow by the fourth quarter of 2003, with substantially narrowed operating losses beginning in 2003.

About Align Technology, Inc.

Align Technology designs, manufactures and markets Invisalign, a proprietary new 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.
