   ALIGN TECHNOLOGY, INC. REPORTS Q2 2005 REVENUES OF $53.9M AND EPS OF $0.01

    SANTA CLARA, Calif., July 20 /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 second quarter of 2005. Total revenues for the second quarter
of 2005 were $53.9 million, compared to $44.2 million in the second quarter of
2004, an increase of 22.0 percent.

    "We are pleased with our financial results for the second quarter 2005,
especially given the emergence of competition in the marketplace," stated
Thomas M. Prescott, Align Technology's President and CEO. "Align is on track
to execute key strategic programs, and our employees are as excited and
committed as ever to building a great company for our customers and
shareholders."

    The net profit for the second quarter of 2005, as reported on a GAAP
basis, was $538 thousand, or earnings per share (EPS) of $0.01. This compares
to a GAAP net profit of $3.8 million for the second quarter of 2004, or EPS of
$0.06 per share. For comparison purposes, this also compares to a non-GAAP net
profit of $5.6 million for the second quarter of 2004 or non-GAAP EPS of
$0.09. Non-GAAP net profit excludes the effects of stock-based compensation.
The reconciliation of the GAAP to non-GAAP measurements for net profit and EPS
is set forth below within Align Technology's financial statements.

    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 April 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.

NON-GAAP CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS (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 profit, which is adjusted to exclude certain costs and expenses and any associated tax effects of such adjustments. We believe that our non-GAAP net profit 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 profit 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 profit prepared in accordance with generally accepted accounting principles in the United States of America.
