Align Technology, Inc. Files Registration Statement for Proposed Initial Public Offering of Common Stock

SANTA CLARA, CALIFORNIA (November 15, 2000) – Align Technology, Inc. announced today that it has filed a registration statement with the Securities and Exchange Commission for a proposed initial public offering of its common stock.

All of the shares in the proposed offering are being sold by Align Technology. Deutsche Banc Alex. Brown is acting as book-running manager for the offering and Bear, Stearns & Co., Inc., J.P. Morgan & Co. and Robertson Stephens are co-managers for the offering.

Align Technology designs, manufactures and markets the Invisalign System^TM, a proprietary new method for treating malocclusion, or the misalignment of teeth. The Invisalign System 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, the Invisalign System significantly reduces the aesthetic and other limitations associated with braces.

Copies of the preliminary prospectus relating to the offering may be obtained, when available, from Deutsche Banc Alex. Brown, One South Street, Baltimore, MD, 21202, (410) 727-1700.

A registration statement relating to these securities has been filed with the Securities and Exchange Commission but has not yet become effective. These securities may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective. This press release shall not constitute an offer to sell or a solicitation of an offer to buy nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.

This release may contain forward-looking statements based on Align Technology’s current expectations. These forward-looking statements involve risks and uncertainties. A number of important factors could cause actual results to differ materially from those in the forward-looking statements. These factors include Align Technology’s ability to achieve profitability, the adoption by orthodontists and consumers of the Invisalign System, Align Technology’s successful enforcement of its intellectual property and avoidance of infringement on third party patents, Align Technology’s ability to establish and maintain reliable, high-volume manufacturing capacity in the U.S. and internationally and Align Technology’s ability to manage its significant growth and retain its key personnel. These factors, as well as other factors that could cause actual results to differ materially, are discussed in more detail in Align Technology’s registration statement on Form S-1, as well as other reports and documents filed from time to time with the Securities and Exchange Commission.
