99.1 Press Release of Align Technology, Inc. dated July 18, 2013

Align Technology Announces Second Quarter Fiscal 2013 Results

SAN JOSE, CA -- (Marketwired - July 18, 2013) - Align Technology, Inc. (NASDAQ: ALGN)

Align Technology, Inc. (NASDAQ: ALGN) today reported financial results for the second quarter ended June 30, 2013.

Total net revenues for the second quarter of fiscal 2013 (Q2 13) were $163.8 million. This is compared to $153.6 million reported in the first quarter of 2013 (Q1 13) and compared to $145.6 million reported in the second quarter of 2012 (Q2 12). Q2 13 Invisalign clear aligner revenue was $153.3 million, compared to $141.6 million in Q1 13 and $133.7 million in Q2 12. As expected, Q2 13 clear aligner revenue includes a $1.2 million decrease in revenue due to the change in our mid-course correction policy effective June 15, 2013. Q1 13 clear aligner revenue includes $4.4 million from the planned consolidation of Vivera Retainer product shipments, as well as a $2.7 million decrease in revenue due to the change in our mid-course correction policy. Q2 13 Invisalign clear aligner case shipments were a record 106.1 thousand, compared to 98.2 thousand in Q1 13 and 95.3 thousand in Q2 12. Q2 13 scanner and CAD/CAM services revenue was $10.5 million, compared to $12.0 million in Q1 13 and compared to $11.9 million in Q2 12. Q1 13 scanner and CAD/CAM services revenue includes $1.4 million that was deferred in Q3 and Q4 2012 for the new iTero scanner upgrade program which was launched in Q1 13.

"I'm pleased to report another good quarter with better than expected revenues, gross margins and earnings," said Thomas M. Prescott, Align president and CEO. "Strong second quarter results were driven by higher Invisalign volumes and ASPs, with sequential growth across all customer channels."

Net profit for Q2 13 was $29.3 million, or $0.36 per diluted share. This is compared to net loss of $42.0 million, or $(0.52) per diluted share in Q1 13 and net profit of $28.5 million, or $0.34 per diluted share in Q2 12. Net loss for Q1 13 includes an impairment of long-lived assets of $26.3 million and a goodwill impairment charge of $40.7 million. Net profit for Q2 12 includes pre-tax acquisition and integration related costs of $0.3 million, pre-tax severance and benefit costs of $0.2 million with a total income tax-related adjustment of $0.8 million.

As previously announced, beginning May 1, 2013 the six indirect country markets of Australia, New Zealand, Hong Kong, Singapore, Macau and Malaysia reverted back to a direct Invisalign sales region for us. We have completed the transition and began to recognize direct sales at our full Invisalign average sales price (ASP), rather than the significantly discounted ASP under the distribution agreement.

As of June 15, 2013, we no longer charge a fee associated with mid-course correction orders. Mid-course correction provides Invisalign customers with the option of ordering a treatment adjustment during active treatment if the case is not tracking to the original treatment plan or goals, giving doctors the ability to "adjust course" based on the needs of the individual patient. We now include up to three free mid-course correction orders per case in our list prices for Invisalign Full and Invisalign Teen products. As a result, Invisalign clear aligner revenue for Q2 13 was decreased by $1.2 million, which reflects the revenue deferred to provide free mid-course corrections for open cases shipped between April 1 through June 15, 2013 that are now eligible for the new mid-course correction policy. In Q1 13, Invisalign clear aligner revenue was decreased by $2.7 million, which reflected the estimated deferred revenue for open cases as of March 31, 2013 that were expected to be eligible for the new policy.

To supplement our consolidated financial statements, we use the following non-GAAP financial measures: non-GAAP gross profit, non-GAAP operating expense, non-GAAP operating margin, non-GAAP net profit, non-GAAP earnings per diluted share, EBITDA and adjusted EBITDA. Detailed reconciliations between GAAP and non-GAAP information are contained in the tables following the financial tables of this release. Starting in fiscal year 2013, amortization of acquired intangible assets is no longer excluded as a non-GAAP measure. This expense is included in GAAP gross profit, operating expenses, profit (loss) from operations and net profit (loss) for the periods presented below and therefore is no longer a reconciling item.

About non-GAAP Financial Measures
To supplement our consolidated financial statements and our business outlook, we use the following non-GAAP financial measures: non-GAAP gross profit, non-GAAP operating expenses, non-GAAP profit from operations, non-GAAP net profit and non-GAAP earnings per share, which exclude, as applicable, acquisition and integration related costs, severance and benefit costs, impairment of goodwill, impairment of long-lived assets and any related income tax-related adjustments, and EBITDA and adjusted EBITDA. 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.

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 expenditures and other items that may not be indicative of our operating performance including discrete cash and non-cash charges that are infrequent or one-time in nature. 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 facilitate comparisons with prior and subsequent reporting periods. A reconciliation of the GAAP and non-GAAP financial measures for the quarter and year and a more detailed explanation of each non-GAAP financial measure and its uses are provided in the footnotes to the table captioned "Reconciliation of GAAP to non-GAAP Key Financial Metrics" and "Business Outlook Summary" included at the end of this release.

Starting in fiscal year 2013, amortization of acquired intangible assets is no longer excluded as a non-GAAP measure. This expense is included in GAAP gross profit, operating expenses, profit (loss) from operations and net profit (loss) for the periods presented below and therefore is no longer a reconciling item.

(1) Acquisition costs and integration related. We have incurred acquisition-related and other expenses which include legal, banker, accounting and other advisory fees of third parties, retention bonuses, integration and professional fees. We do not engage in acquisitions in the ordinary course of business. We believe that it is important to understand these charges; however, we do not believe that these charges are indicative of future operating results. We believe that eliminating these expenses from our non-GAAP measures is useful because we generally would not have otherwise incurred such expenses in the periods presented as part of our continuing operations.

(2) Severance and benefits costs. These costs are related to the closure of our New Jersey operations and were realized through the first three quarters of 2012. We have engaged in various restructuring and exit activities in 2011 and 2009 that have resulted in costs associated with severance and benefits. Such activity has been a discrete event based on a unique set of business objectives or circumstances, and each has differed from the others in terms of its operational implementation, business impact and scope. We do not engage in restructuring and/or exit activities in the ordinary course of business. We believe that it is important to understand significant severance and benefits costs from restructuring and exit activities and believe that investors benefit from excluding these charges from our operating results to facilitate a more meaningful evaluation of current operating performance and comparisons to past operating performance.

(3) Impairment of goodwill. These costs represents non-cash write-downs of our goodwill generally related to negative trends in market and economic conditions, termination of relationships with distributors, or the increase in completive environment related to our Scanner and CAD/CAM Services reporting unit. We remove the impact of these charges to our operating performance to assist in assessing our ability to generate cash from operations. We believe this may be useful information to users of our financial statements and therefore we have excluded these charges for purposes of calculating these non-GAAP measures to facilitate an evaluation of our current operating performance, particularly in terms of liquidity.

(4) Impairment of long-lived assets. These costs represent non-cash write-downs of our long-lived assets generally related to the increase in completive environment related to our Scanner and CAD/CAM Services reporting unit. As a result of these conditions, we have assessed that our asset group within the reporting unit was not recoverable and therefore recorded an impairment charge. We remove the impact of these charges to our operating performance to assist in assessing our ability to generate cash from operations. We believe this may be useful information to users of our financial statements and therefore we have excluded these charges for purposes of calculating these non-GAAP measures to facilitate an evaluation of our current operating performance, particularly in terms of liquidity.

(5) Income tax-related adjustments. Non-GAAP financial information for the quarter is adjusted for a tax rate equal to our annual estimated tax rate on non-GAAP income. This rate is based on our estimated annual GAAP income tax rate forecast, adjusted to account for discrete tax items and items excluded from GAAP income in calculating the non-GAAP financial measures presented above. Our estimated tax rate on non-GAAP income is determined annually and may be re-calculated during the year to take into account events or trends that we believe materially impact the estimated annual rate.

(6) EBITDA and adjusted EBITDA. We use EBITDA as a performance measure for benchmarking against our peers and competitors. We believe EBITDA is useful to investors because it is frequently used by securities analysts, investors and other interested parties to evaluate companies in the medical technology industry. We also use adjusted EBITDA which excludes certain special or non-recurring expenses, net of certain special or non-recurring benefits, detailed in the reconciliation tables that accompany this release, as an internal measure of business operating performance. We believe such financial measures provide a meaningful perspective of the underlying operating performance to our current business. EBITDA and adjusted EBITDA are not recognized terms under GAAP. Because all companies do not calculate EBITDA and similarly titled financial measures in the same way, those measures as used by other companies may not be consistent with the way we calculate such measures and should not be considered as alternative measures of operating or net profit.
