                  FOR Q4 2005 AND $207.1M FOR FISCAL YEAR 2005

     SANTA CLARA, Calif., Jan. 25 /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 2005. Total revenues for the fourth
quarter of 2005 were $51.2 million, compared to $50.9 million in the third
quarter of 2005, an increase of 0.6 percent, and $43.7 million in the fourth
quarter of 2004, an increase of 17.2 percent. For fiscal year 2005, Align
reported revenues of $207.1 million, compared to $172.8 million for fiscal year
2004, an increase of 19.8 percent.

     "We are pleased with our results for 2005," stated Thomas M. Prescott,
Align Technology's President and CEO. "Revenues were up 20 percent and case
volumes grew by 23 percent. We continued to provide value for our customers
through our national advertising campaign, new products and software, superb
clinical education events, and new pricing initiatives. In 2006, we will
continue our strategy of ensuring product leadership, being responsive to our
customers' needs, and improving operational effectiveness across the company.
Delivering on this strategy, combined with our superior value proposition for
customers, will enhance shareholder value."

     The net profit for the fourth quarter of 2005, as reported on a GAAP basis,
was $528 thousand, or earnings per share (EPS) of $0.01. This compares to GAAP
net profit of $1.1 million for the fourth quarter of 2004, or EPS of $0.02 per
share. For comparison purposes, this also compares to a non-GAAP net profit of
$1.3 million for the fourth quarter of 2004 or non-GAAP EPS of $0.02. Non-GAAP
net profit excludes the effects of stock-based compensation.

     For fiscal year 2005, the net profit was $1.4 million, or EPS of $0.02.
This compares to a GAAP net profit of $8.8 million for fiscal year 2004, or EPS
of $0.14 per share. For comparison purposes, this also compares to a non-GAAP
net profit of $14.4 million for fiscal year 2004, or EPS of $0.22. 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 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.

ALIGN TECHNOLOGY, INC. 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.
