    SANTA CLARA, Calif., Jan. 30 /PRNewswire-FirstCall/ -- Align Technology,
Inc. (Nasdaq: ALGN), the inventor of Invisalign(R), a proprietary method of
straightening teeth without wires and brackets, today reported financial results
for the fourth quarter and full year of 2006. Total revenues for the fourth
quarter of 2006 were $55.2 million, compared to $51.2 million in the fourth
quarter of 2005, an increase of 7.9 percent. For fiscal year 2006, Align
reported revenues of $206.4 million, compared to $207.1 million for fiscal year
2005, a decrease of 0.4 percent.

    "2006 was eventful and productive," stated Thomas M. Prescott, President and
CEO of Align Technology. "We resolved our legal disputes with OrthoClear and
refocused our efforts on product development, customer service and market
expansion. Overall, we shipped a record number of cases and our base of doctors
grew tremendously. We expect 2007 to be the year we restage growth, introduce
products that meet the unique needs of the Orthodontists and GPs and continue
our path to profitability."

    Revenue Analysis

    Revenue was $55.2 million for the fourth quarter, an increase of 7.9% from
the fourth quarter of 2005, and $206.4 million for the year ended December 31,
2006, a decrease of 0.4% over the prior year. In the fourth quarter, revenue per
channel was:

    * $17.4 million for U.S. Ortho, including $2.0 million for Invisalign
      Express;

    * $24.5 million for U.S. GP, including $2.9 million for Invisalign
      Express;

    * $9.6 million for International; and

    * $3.7 million for Other.

    Key metrics include:

    * 3,700 U.S. Orthos, 9,000 U.S. GPs, and 2,100 International doctors
      submitted cases in the fourth quarter. Also in the fourth quarter, cases
      were shipped to 3,400 U.S. Orthos, 7,900 U.S. GPs and 1,900
      International doctors.

    * Utilization in the fourth quarter of 2006 was 4.2 for U.S. Orthos, 2.4 for
      U.S. GPs, and 2.9 for International. Utilization in the ortho channel
      declined because a large number of doctors, who had not started cases in
      the previous year, started new Invisalign cases in the fourth quarter.
      Utilization was flat in the U.S. GP channel and slightly up in
      international.

    * In the fourth quarter, worldwide average selling price (ASP) for
      Invisalign was $1,320. Excluding Invisalign Express, worldwide ASP was
      $1,445.

    * Total number of cases shipped in fiscal year 2006 increased 22% to
      150,100. Included in this were 36,600 Invisalign Express cases.

    * Doctors trained worldwide in fiscal year 2006 increased by 5,000,
      including 3,800 U.S. GP dentists, to a cumulative total of 40,800.



    * Since product inception, 28,700 doctors worldwide have used Invisalign:
      6,200 U.S. Orthos; 17,200 U.S. GPs; and 5,300 International doctors. 84
      percent of these doctors have started more than one case.

    A full list of quarterly metrics is available in the Fact Sheet following
the financial tables of this release. Additionally, quarterly metric information
for the last 8 quarters is available on Align's website at
investor.aligntech.com.

    Operating results reflect stock-based compensation expense of $2.2 million
for Q4 and $8.9 million for full year 2006 due to the implementation of FAS 123(
R ) in the first quarter of 2006. It also reflects $14.3 million of one- time
costs incurred from our agreement with OrthoClear including settlement costs and
costs associated with the Patients First Program. These items have been excluded
in the non-GAAP financials. A reconciliation of GAAP (U.S. generally accepted
accounting principles) to non-GAAP results and outlook is contained in the

    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.

    To learn more about Invisalign or to find a certified Invisalign doctor in
your area, please visit www.invisalign.com or call 1-800-INVISIBLE.



    About non-GAAP Financial Measures

    To supplement our consolidated financial statements, which statements are
prepared and presented in accordance with GAAP, we use the following non-GAAP
financial measures: non-GAAP gross profit, profit (loss) from operations, net
profit (loss) and certain expenses (including sales and marketing, general and
administrative and research and development), which exclude stock-based
compensation and the Patients First Program and settlement costs. The
presentation of this financial information is not intended to be considered in
isolation or as a substitute for, or superior to, the financial information
prepared and presented in accordance with GAAP. For more information on these
non-GAAP financial measures, please see the tables captioned "Reconciliation of
GAAP to Non-GAAP Condensed Consolidated Statements of Operations" and "Business
Outlook" included at the end of this release.

    We use these non-GAAP financial measures for financial and operational
decision making and as a means to evaluate period-to-period comparisons. Our
management believes that these non-GAAP financial measures provide meaningful
supplemental information regarding our "core operating performance." Management
believes that "core operating performance" represents Align's performance in the
ordinary, ongoing and customary course of its operations. Accordingly,
management excludes from "core operating performance" certain expenses and
expenditures that may not be indicative of our operating performance including
not only non-cash charges, such as stock-based compensation, but also discrete
cash charges that are infrequent or one-time in nature, such as the Patients
First Program and settlement costs. We believe that both management and
investors benefit from referring to these non-GAAP financial measures in
assessing our performance and when planning, forecasting and analyzing future
periods. These non-GAAP financial measures also facilitate management's internal
evaluation of period-to-period comparisons. We believe these non-GAAP financial
measures are useful to investors both because (1) they allow for greater
transparency with respect to key metrics used by management in its financial and
operational decision making and (2) they are provided to and used by our
institutional investors and the analyst community to help them analyze the
health of our business.

Forward-looking statements contained in this news release and the tables below
relating to expectations about future events or results are based upon
information available to Align as of the date hereof. Readers are cautioned that
these forward-looking statements are only predictions and are subject to risks,
uncertainties and assumptions that are difficult to predict. As a result, actual
results may differ materially and adversely from those expressed in any
forward-looking statement. Factors that might cause such a difference include,
but are not limited to, risks relating to Align's ability to sustain or increase
profitability or revenue growth in future periods while controlling expenses,
including expenses related to the OrthoClear settlement, customer demand for
Invisalign, acceptance of Invisalign by consumers and dental professionals,
Align's third party manufacturing processes and personnel, foreign operational,
political and other risks relating to Align's international manufacturing
operations, Align's ability to protect its intellectual property rights,
competition from manufacturers of traditional braces and new competitors,
Align's ability to develop and successfully introduce new products and product
enhancements, and the loss of key personnel, including members of its direct
sales force. These and other risks are detailed from time to time in Align's
periodic reports filed with the Securities and Exchange Commission, including,
but not limited to, its Annual Report on Form 10-K for the fiscal year ended
December 31, 2005, which was filed with the Securities and Exchange Commission
on March 1, 2006, and its Quarterly Reports on Form 10-Q. Align undertakes no
obligation to revise or update publicly any forward-looking statements for any
