Align Technology, Inc. Reports Record Revenues of $29.2 Million for the Second
                                 Quarter 2003

     - Second Quarter Revenues Increase 86% Year Over Year; Net Loss Decreases
       62% Year Over Year
     - Company to Restate Approximately $9 Million in Prior Period Net
       Revenue; Will Restate Results for FY 2001, FY 2002, and the First
       Quarter of FY 2003
     - Restatement Will Have No Effect on Business Operations, Cash Flow or
       Liquidity

    SANTA CLARA, Calif., July 24 /PRNewswire-FirstCall/ -- Align Technology,
Inc. (Nasdaq: ALGN), the inventor of Invisalign(R), a proprietary method of
straightening teeth without wires and brackets, today reported record revenues
of $29.2 million for the second quarter of 2003.
    "We are pleased with the progress we are making," stated Thomas M.
Prescott, Align Technology's President and CEO. "The solid results delivered
this quarter are driven by adoption and utilization by orthodontists and
general practitioner dentists as they, and their patients, experience
outstanding results first-hand. Our operating profile continues to improve and
we continue to aggressively decrease our net loss. Our focus on the balance
sheet is also showing as we increased our cash resources by over $1 million
this quarter. We have much to do, yet these results should indicate we are on
the right path."

    Second Quarter Results
    The Company reported total revenues for the second quarter of 2003 of
$29.2 million, compared to $23.0 million in the first quarter of 2003, an
increase of 27.3 percent, and $15.7 million in the second quarter of 2002, an
increase of 86.0 percent. The net loss for the second quarter of 2003, as
reported under generally accepted accounting principles ("GAAP"), was $7.8
million, or a net loss per share of $0.13. This compares to a net loss for the
first quarter of 2003 of $10.7 million, or a net loss of $0.19 per share, and
a net loss for the second quarter of 2002 of $20.3 million, or a net loss of
$0.44 per share. Net loss for the second quarter of 2003 was impacted by a
$1.4 million charge to operating expense in connection with sales tax for
which the Company decided during the quarter not to pursue collection from its
customers. In addition, the net loss was impacted by a $400 thousand charge to
cost of revenues related to certain use tax matters. Second quarter of 2002
and first quarter of 2003 GAAP financial data is presented on an as restated
basis.
    Non-GAAP net loss for the second quarter of 2003, which excludes
$4.4 million of stock-based compensation, was $3.4 million, or a non-GAAP net
loss of $0.06 per share, compared to a non-GAAP net loss of $14.5 million, in
the second quarter of 2002, which excludes $5.9 million of stock-based
compensation, or a non-GAAP net loss of $0.31 per share. Non-GAAP net loss for
the second quarter of 2003 included the same charge for sales and use tax of
$1.8 million included in the GAAP net loss above. Non-GAAP second quarter of
2002 and first quarter of 2003 financial data is presented on an as adjusted
basis. The reconciliation of the GAAP to non-GAAP measurements for net loss
for the second quarter of 2003 is set forth below within Align Technology's
financial data.
    As of June 30, 2003, cash, cash equivalents and marketable securities
increased by $1.1 million to $38.4 million, compared to $37.3 million as of
March 31, 2003, without incurring new debt or drawing down on a line of
credit.

    $9.0 Million Net Revenue Restatement
    In conjunction with the Company's adoption during the quarter of Emerging
Issues Task Force Issue No. 00-21, Accounting for Revenue Arrangements with
Multiple Deliverables (EITF 00-21), which addresses the issue of accounting
for arrangements that involve the delivery of multiple products or services,
the Company also reviewed its revenue recognition policies governing case
refinement (a case refinement occurs when Aligners are prescribed by the
clinician for patients needing tooth movements beyond the original
prescription). Based on this review, the Company will reverse previous loss
accruals of approximately $900 thousand and defer net revenues of
approximately $9.0 million recorded in prior periods. These revenues will be
recognized primarily in the second half of fiscal year 2003 and throughout
fiscal year 2004.  The Company will restate its financial results for fiscal
years 2001 and 2002, including the related interim periods, and the first
quarter of 2003.  Revenues will be reduced and deferred by approximately
$1.6 million, $5.7 million and $1.8 million in fiscal year 2001, fiscal year
2002 and the first quarter of fiscal year 2003, respectively.
    The Company stated that these prior period adjustments will have no effect
on business operations, cash flow or liquidity.
    When the Company began offering case refinement as a finishing tool in
June 2001, the Company charged $50 for this product if it was purchased at the
beginning of a treatment period, and $250 if it was purchased during the
course of treatment. The Company deferred $50 of revenue and accrued any
anticipated losses related to the cost of producing and delivering each case
refinement sold at the beginning of the treatment period until either the case
refinement was utilized or upon case expiration. Over the past two years, the
demand for case refinements has been higher than was originally anticipated
when the product was first introduced.
    In light of the aforementioned changes in product demand and the adoption
of EITF 00-21, the Company reevaluated the accounting treatment for case
refinement revenues under the principals contained in Staff Accounting
Bulletin No. 101, Revenue Recognition in Financial Statements (SAB 101), and
related guidance. The Company has determined that the revenue amount deferred
for each case refinement in prior periods should have been $250 rather than
$50, as previously deferred.  The Company's restated financial statements will
reflect this appropriate deferral amount.
    On May 1, 2003, the Company updated its pricing policy to include the
future delivery of one case refinement in the price of each case and to offer
additional case refinements at a price of $125 each, which the Company
believes represents the fair value based on competitive product offerings.
Revenue deferrals associated with future case refinements will be $125, which
was determined in a manner consistent with the newly adopted rules contained
in EITF 00-21. These revenue deferrals will be recognized when the case
refinement has been utilized or upon case expiration.
    The Company expects to file its amended 2002 Annual Report on Form 10-K,
which will include the restated consolidated financial statements for the
years 2002 and 2001 and the corresponding interim periods, and its amended
10-Q for the first quarter of 2003 as soon as possible. The Company does not
propose to file amendments to its Quarterly Report on Form 10-Q for the
quarters ending June 30, 2001 through September 30, 2002, nor their Annual
Report on Form 10-K for the year ending December 31, 2001, and accordingly,
these filings should be disregarded.

July 24, 2003 at 5:00 p.m. EDT, 2:00 p.m. PDT, to review second quarter of

    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.

     (unaudited)

    Use of Non-GAAP Financial Information
    To supplement our condensed consolidated financial statements presented on
a GAAP basis, Align uses a non-GAAP measure of net loss, which is adjusted to
exclude certain costs and expenses.  We believe that our non-GAAP net loss
gives an indication of our baseline performance before other charges that are
considered by management to be outside of our core operating results.  In
addition, our non-GAAP net loss is among the primary indicators management
uses as a basis for our planning and forecasting of future periods.  The
presentation of this additional information should not be considered in
isolation or as a substitute for net loss prepared in accordance with

    Use of Non-GAAP Financial Information
    To supplement our condensed consolidated financial statements presented on
a GAAP basis, Align uses a non-GAAP measure of net loss, which is adjusted to
exclude certain costs and expenses.  We believe that our non-GAAP net loss
gives an indication of our baseline performance before other charges that are
considered by management to be outside of our core operating results.  In
addition, our non-GAAP net loss is among the primary indicators management
uses as a basis for our planning and forecasting of future periods.  The
presentation of this additional information should not be considered in
isolation or as a substitute for net loss prepared in accordance with
generally accepted accounting principles in the United States of America.
