ITEM 1.

BUSINESS

Our Company

PART I

Align Technology, Inc. (“We”, “Our”, “Align”) is a global medical device company engaged in the design, manufacture and marketing of Invisalign® clear aligners and iTero® intraoral scanners and services for orthodontics, and
restorative and aesthetic dentistry. Align’s products are intended primarily for the treatment of malocclusion or the misalignment of teeth and are designed to help dental professionals achieve the clinical outcomes that they expect. Align
Technology was founded in March 1997 and incorporated in Delaware in April 1997. Our corporate headquarters is located at 2820 Orchard Parkway, San Jose, California, U.S.A., 95134, and our telephone number is 408-470-1000. Our
internet address is www.aligntech.com. Our Americas regional headquarters is located in Raleigh, North Carolina, U.S.A.; our European, Middle East and Africa (“EMEA”) regional headquarters is located in Rotkreuz, Switzerland, which
moved from Amsterdam, the Netherlands in January 2020; and our Asia Pacific ("APAC") regional headquarters is located in Singapore.

We have two operating segments: (1) Clear Aligner and (2) Scanners and Services ("Scanner"). For the year ended December 31, 2019, Clear Aligner net revenues represented approximately 84% of worldwide net revenues, while
Scanner net revenues represented the remaining 16% of worldwide net revenues. We sell the majority of our products directly to our customers: orthodontists and general practitioner dentists ("GPs"), as well as to restorative and aesthetic
dentists, including prosthodontists, periodontists, and oral surgeons. We also sell through sales agents and distributors in certain countries. In addition, we sell directly to Dental Support Organizations ("DSOs") who contract with dental
practices to provide critical business management and support including non-clinical operations, and we sell directly to dental laboratories who manufacture or customize a variety of products used by licensed dentists to provide oral health
care.

We received 510(k) clearance from the United States Food and Drug Administration (“FDA”) to market the Invisalign System in 1998. The Invisalign System is regulated by the FDA as a Class II medical device. In order to provide
Invisalign treatment to their patients, orthodontists and GPs must initially complete an Invisalign training course. The Invisalign System is sold primarily through a direct sales force in North America, APAC, Europe, EMEA and Latin
America ("LATAM"). To date, over 8 million people worldwide have been treated with our Invisalign System.

Our iTero scanner is used by dental professionals and/or labs and service providers for restorative and orthodontic digital procedures as well as Invisalign case submission. We received 510(k) clearance from the FDA to market iTero

software for expanded indications in 2013. Scanners and computer-aided design/computer-aided manufacturing ("CAD/CAM") services are primarily

3

 
sold through our direct sales force and through sales agents and distributors in certain countries. In addition, we sell iTero scanners and CAD/CAM services directly to DSOs.

Clear Aligner Segment

Malocclusion and Traditional Orthodontic Treatment

Malocclusion, or the misalignment of teeth, is one of the most prevalent clinical dental conditions, affecting billions of people, or approximately 60% to 75% of the global population. Annually, approximately 12 million people in
major developed countries elect treatment by orthodontists worldwide. Most orthodontic patients are treated with the use of traditional methods such as metal arch wires and brackets, referred to as braces, and may be augmented with
elastics, metal expanders, headgear or functional appliances, and other ancillary devices as needed. Upon completion of the treatment, the dental professional may, at his or her discretion, have the patient use a retainer appliance. Of the 12
million  annual  orthodontic  cases  started,  we  estimate  that  approximately  75%  or  8.4  million  could  be  treated  using  our  Invisalign  clear  aligners.  In  addition,  approximately  300  million  people  with  malocclusion  could  benefit  from
straightening their teeth. This represents an incremental opportunity for us as we expand the market for orthodontics by educating more consumers about the benefits of straighter teeth using Invisalign clear aligners and connecting them
with an Invisalign doctor of their choice.

The Invisalign System

The Invisalign System is a proprietary method for treating malocclusion based on a proprietary computer-simulated virtual treatment plan and a series of doctor-prescribed, custom manufactured, clear plastic removable aligners. The

Invisalign System offers a range of treatment options, specialized services, and access to proprietary software for treatment visualization and is comprised of the following phases:

Orthodontic diagnosis and transmission of treatment data to us. The Invisalign-trained dental professional prepares an online prescription form on our Invisalign Doctor Site and submits the patient's records, which include a digital
intraoral scan or a polyvinyl-siloxane ("PVS") impression of the relevant dental arches, photographs of the patient and, at the dental professional’s election, x-rays of the patient’s dentition. Intraoral digital scans may be submitted through
either Align's iTero scanner or certain third-party scanners capable of accurately interfacing with our systems and processes. See "Third Party Scanners and Digital scans for Invisalign treatment submission." More than 73% of Invisalign
case submissions are now submitted via digital scan, increasing the accuracy of treatments, reducing the time from prescription submission to patient receipt, and decreasing the carbon footprint resulting from the shipment of the materials
used to form the physical PVS impressions and shipping those PVS impressions to us.

Preparation of computer-simulated treatment plan. Using the information and digital data provided, we generate a proposed custom, three-dimensional treatment plan, called a ClinCheck treatment plan using our proprietary software,
which is not for sale or license. A patient’s ClinCheck treatment plan simulates expected tooth movement in stages and details the timing and placement of any features or attachments to be used during treatment. Attachments are tooth-
colored “buttons” that are sometimes used to increase the biomechanical force on a specific tooth or teeth in order to effect the desired movement(s).

Review and approval of the treatment plan by an Invisalign-trained doctor. The patient’s ClinCheck treatment plan is then made available to the prescribing dental professional via the Invisalign Doctor Site which enables the dental
professional to project tooth movement from initial position to final position and compare multiple treatment plan options. By reviewing, modifying as needed and approving the treatment plan, the dental professional retains control of the
patient's treatment.

Manufacture  of  custom  aligners.  Upon  the  dental  professional’s  approval  of  the  ClinCheck  treatment  plan,  we  use  the  data  underlying  the  simulation,  in  conjunction  with  stereolithography  technology  (a  form  of  3D  printing
technology), to construct a series of molds depicting the future position of the patient’s teeth. Each mold is a replica of the patient’s teeth at each stage of the simulated course of treatment. From these molds, aligners are fabricated by
pressure-forming polymeric sheets over each mold. Aligners are thin, clear plastic, removable dental appliances that are custom manufactured in a series to correspond to each stage of the patient's ClinCheck treatment plan.

Shipment to the dental professional and patient aligner wear. In most countries, all the aligners for a patient's treatment plan are shipped directly to the dental professional, who then dispenses them to the patient at regular check-up
intervals throughout the treatment. Aligners are generally worn for a period of time typically one to two weeks, corresponding to the stages of the patient’s approved ClinCheck treatment plan. The patient replaces the aligners with the next
pair in the series when prescribed, advancing tooth movement through each stage. At various points in each patient’s treatment, their doctor may place attachments or use other auxiliaries to achieve desired tooth movements, per the
doctor’s original prescription and the approved ClinCheck treatment plan.

4

At the treating doctor’s discretion, weekly aligner changes are recommended for all Invisalign treatments except for Invisalign Lite and Express packages and may provide up to 50% shorter treatment time compared with two-week aligner
wear.

Feature Enhancements

We continue to introduce enhanced features across the Invisalign System to improve treatment outcomes or address broader clinical indications. For example, in 2018, we extended the Invisalign product family with Invisalign First
clear aligners, designed with features specifically for younger patients with early mixed dentition (with a mixture of primary/baby and permanent teeth). Invisalign First clear aligners are designed specifically to address a broad range of
younger patients' malocclusions, including shorter clinical crowns, management of erupting dentition, and predictable dental arch expansion.

In 2018, we also introduced enhancements designed to improve dental professional and patient experiences and clinical outcomes including: wing overlap and engagement in deep bite cases with anterior intrusion, new options for

mandibular advancement and symmetrical advancement of the left and right side, a new default protocol for incremental advancement, and improvements to support leveling the curve of Spee in deep bite cases.

Most of our Invisalign Treatment Plans described above provide dental professionals with the option to order additional aligners if the patient's treatment is not tracking against the original treatment plan. The number of additional

aligner orders and timing are subject to certain requirements noted in our terms and conditions.

Comprehensive Products - Invisalign Treatment Options:

Invisalign Comprehensive. The Invisalign Comprehensive Package is used to treat adults and teens for a full spectrum of mild to severe malocclusion and contains a wide variety of Invisalign features to address the doctor's treatment

goals. It also addresses the orthodontic needs of teenage patients, such as Mandibular Advancement, compliance indicators and compensation for tooth eruption.  

Invisalign  First  Phase  1  and  Invisalign  First  Comprehensive  Phase  2  Package.  Invisalign  First  Phase  1  is  designed  specifically  for  younger  patients  generally  between  the  ages  of  seven  and  ten  years,  which  is  a  mixture  of
primary/baby and permanent teeth. Invisalign First Phase 1 treatment provides early interceptive orthodontic treatment, traditionally done through arch expanders, or partial metal braces, before all permanent teeth have erupted. Invisalign
First clear aligners are designed specifically to address a broad range of younger patients' malocclusions, including shorter clinical crowns, management of erupting dentition and predictable dental arch expansion. Our Invisalign First
Comprehensive Phase 2 Package is a continuation of the First Phase 1 and is generally consistent with our Invisalign Comprehensive Package. After a patient completes Invisalign First Phase I, doctors have the option to purchase a
discounted Comprehensive Phase 2 Package for that same patient.

Non-Comprehensive Products - Invisalign Treatment Options:

Invisalign Non-comprehensive Products. We offer a variety of lower priced treatment packages for less complex orthodontic cases, non-comprehensive relapse cases, or straightening prior to restorative or cosmetic treatments, such as

veneers. These packages may be offered in select countries and/or may differ from region to region.

5

    
Invisalign Go. We also offer Invisalign Go, a streamlined Non-Comprehensive package designed for GPs to more easily identify and treat patients with mild malocclusion. The Invisalign Go package includes case assessment support,

a simplified ClinCheck treatment plan and a progress assessment feature for case monitoring.

Non-Case Products:

Clear Aligner non-case products include retention products, Invisalign training fees and sales of ancillary products, such as cleaning material and adjusting tools used by dental professionals during the course of treatment.

Retention. We offer up to four sets of custom clear aligners called Vivera Retainers made with proprietary material strong enough to maintain tooth position and correct minor relapse, if necessary. Vivera Retainers are available to

both Invisalign and non-Invisalign patients. In select markets, we also offer single arch retainers.

SmartTrack Aligner Material

SmartTrack is a patented, custom-engineered Invisalign clear aligner material that delivers gentle, more constant force considered ideal for orthodontic tooth movements. Conventional aligner materials relax and lose a substantial
percent of energy in the initial days of aligner wear, but SmartTrack maintains more constant force over the period of time the patient wears the aligners. The flexible SmartTrack material also more precisely conforms to tooth morphology,
attachments and interproximal spaces to improve control of tooth movement throughout treatment.

Scanner Segment

Intraoral scanning continues to be an evolving technology that we believe will have a substantial impact on the future of dentistry. By enabling the dental practitioner to create a 3D image of a patient's teeth (digital scan) using a
handheld  intraoral  scanner,  digital  scanning  is  faster,  more  efficient,  precise  and  comfortable  for  patients,  compared  to  the  discomfort  and  subjective  nature  of  taking  physical  impressions.  The  accuracy  of  digitally  scanned  models
substantially reduces the rate of restoration "remakes;" meaning patients are recalled less often and the appointment time for the restoration is shorter because of fewer adjustments, increasing overall patient satisfaction. Digital models also
reduce the carbon footprint associated with the shipping of the materials used to create PVS impressions, the shipping of those impressions, and their disposal. Moreover, the digital model file can be used for various procedures and
services including fabrication of physical dental models for use by labs to create restorative units such as veneers, inlays, onlays, crowns, bridges and implant abutments; digital records storage; orthodontic diagnosis; orthodontic retainers
and appliances; and Invisalign digital impression submission.

iTero Scanner. The iTero Element scanner is available as a single hardware platform with software options for restorative or orthodontic procedures. The expanded portfolio includes the iTero Element 2 and the iTero Element Flex
scanners which are each available in select regions and countries. These products build on the existing high precision, full-color imaging and fast scan times of the iTero Element portfolio while streamlining orthodontic and restorative
workflows. We also continue to offer the existing iTero Element scanner in existing markets. The iTero scanner is interoperable with our Invisalign treatment such that a full arch digital scan can be submitted as part of the Invisalign case
submission process.

In February 2019, we launched the iTero Element 5D Imaging system which provides a new comprehensive approach to clinical applications, workflows and user experience that expands the suite of existing high-precision, full-color
imagining and fast scan times of the iTero Element portfolio. In addition to offering all of the features and functionality that doctors have come to expect and rely on with the iTero Element 2 scanner, the iTero Element 5D scanner is the
first integrated dental imaging system that simultaneously records 3D, intra-oral color and near-infrared ("NIRI") imaging and enables comparison over time using iTero TimeLapse. NIRI technology of the iTero Element 5D Imaging
System aids in detection and monitoring of interproximal caries lesions above the gingiva without using harmful radiation. The iTero Element 5D Imaging System is available in the majority of EMEA and select APAC countries; however,
it is pending regulatory approval in the U.S. and LATAM countries.

In June 2019, we announced the launch of iTero Element Foundation intraoral scanner with restorative software. The iTero Element Foundation extends our portfolio of intraoral scanners with powerful 3D visualization to better meet

the needs of doctors, labs and patients. The iTero Element Foundation is available in North America and Japan and will be available in other select APAC and EMEA countries in 2020.

Restorative software for iTero. Our Restorative software is designed for GPs, prosthodontists, periodontists, and oral surgeons which includes restorative workflows providing them with the ability to send digital impressions to the lab

of choice and communicate seamlessly with external treatment planning, custom implant abutment, chairside milling, and laboratory CAD/CAM systems.

6

Orthodontic software for iTero. Software designed for orthodontists for digital records storage, orthodontic diagnosis, and for the fabrication of printed models and retainers. 

CAD/CAM Services and Ancillary Products

Ancillary Products. We sell disposable sleeves for the wand and other ancillary products for the iTero scanner.

iTero Models and Dies. An accurate physical model and dies are manufactured based on the digital scan and sent to the laboratory of the dentist’s choice for completion of the needed restoration. The laboratory also has the option to
export the digital file for immediate production of coping and full-contour restorations on their laboratory CAD/CAM systems. The laboratory conducts then completes the ceramic buildup or staining and glazing and delivers the end result
- a precisely fitting restoration. iTero prosthetics have a near-zero remake rate.

Third Party Scanners and Digital scans for Invisalign treatment submission. We accept case submissions for our clear aligner products in two ways: (1) physical impressions of the patient’s teeth or (2) intraoral scan of the patient’s

teeth. With respect to intraoral scans, we accept scans from iTero scanners and certain third-party scanners that have interoperability relationship with our systems and processes.

iTero Applications and Tools

Invisalign Outcome Simulator. The Invisalign Outcome Simulator is an exclusive chair-side and cloud-based application for the iTero scanner that allows doctors to help patients visualize how their teeth may look at the end of

Invisalign treatment. This is achieved through a dual view layout that shows a prospective patient an image of his/her own current dentition next to his/her simulated final position after Invisalign treatment.

Invisalign  3D  Assessment  tool.  The  Invisalign  Progress  Assessment  tool  provides  the  ability  to  compare  a  patient’s  new  scan  with  a  specific  stage  of  their  ClinCheck  treatment  plan.  This  allows  doctors  to  visually  assess  and

communicate Invisalign treatment progress with an easy to read, color-coded tooth movement report.

TimeLapse. TimeLapse  technology  allows  doctors  or  practitioners  to  compare  a  patient’s  historic  3D  scans  to  the  present-day  scan,  enabling  clinicians  to  identify  and  measure  orthodontic  movement,  tooth  wear,  and  gingival

recession. This highlights areas of diagnostic interest to dental professionals and helps foster a proactive conversation with the patient regarding potential restorative or orthodontic solutions.

Our iTero Element, iTero Element 2, iTero Element Flex and iTero Element 5D scanners include the Invisalign Outcome Simulator, Invisalign 3D Assessment tool and Timelapse as well as the orthodontic software and/or restorative

software. The orthodontic or restorative software may also be purchased subsequently for an upgrade fee. Additional applications such as the Invisalign Outcome Simulator are not available for sale separately.

Other proprietary software mentioned in this Annual Report on Form 10-K such as ClinCheck and ClinCheck Pro software, the Invisalign Doctor Site, and feature enhancements are included as part of the Invisalign System and are

not sold separately nor do they contribute as individual items to revenues.

Business Strategy

Our goal is to establish the Invisalign System as the standard method for treating malocclusion and our intraoral scanning platform as the preferred scanning protocol for digital scans. Our technology and innovations are designed to
meet the demands of today’s patients with treatment options that are convenient, comfortable, affordable, while helping to improve overall oral health. We strive to help our doctors move their practices forward by connecting them with
new patients, providing digital solutions to help increase practice efficiency and helping them deliver the best possible treatment outcomes and experiences to millions of people around the world. We achieve this by continued focus and
execution of our strategic growth drivers as follows:

1.

International Expansion. In order to provide the millions of consumers access to a better smile, we continue increasing our presence globally by making our products available in more countries. We expect to continue expanding
our business by investing in resources, infrastructure, and initiatives that will drive Invisalign treatment growth in our current and new international markets. As our core international countries continue to grow in both number of
new Invisalign trained doctors and customer utilization, we strive to make sure we can support that growth through investments such as headcount, clinical support, product improvements, education and advertising. We have
transitioned most of our smaller country markets from an indirect to a direct sales model, and, while we do not expect a material impact from these countries for

7

some time, in the near term we will leverage our existing infrastructure in adjacent country markets as we build local sales and support organizations to drive long-term market penetration. In addition, we are scaling and expanding
our operations and facilities to better support our customers across the globe. In 2019, we opened a new order acquisition and treatment facility in Wroclaw, Poland and a new treatment planning facility in Yokohama, Japan to
support customers within these regions.

2. GP Adoption. We want to enable GPs, who have access to a large patient base, to more easily identify Invisalign cases they can treat, monitor patient progress or, if needed, help refer cases to an orthodontist while providing high-
quality restorative, orthodontic, and dental hygiene care. In 2019, we continued to commercialize Invisalign Go, a simplified and streamlined solution designed for GPs and trained over 3,700 new Invisalign Go doctors primarily
in EMEA. In the EMEA region, we segmented sales and marketing for certain country markets into two separate organizations to serve each customer segment, orthodontists and GP dentists separately, thereby increasing our focus
and effectiveness on GP dentists. The iTero scanner is an important component to that customer experience and is central to a digital approach as well as overall customer utilization of Invisalign treatment. The iTero scanner is
optimized for Invisalign treatment with the Invisalign Outcome Simulator, Invisalign Progress Assessment tool, and TimeLapse technology. This highlights areas of diagnostic interest to dental professionals and helps foster a
proactive conversation with the patient regarding potential restorative or orthodontic solutions. In March 2019, we began a collaboration with Digital Smile Design to deliver dedicated education programs, enable simplified,
streamlined integration of digital end-to-end workflows into GPs' practices and offer doctors more opportunities to learn about digital tools and treatment planning support. In September 2019, we formed a collaboration with
Zimmer Biomet Dental to leverage their extensive direct global salesforce and network of dental clinicians and laboratories to help drive further penetration of iTero scanners and services in the growing digital restorative market.
The collaboration also offers Zimmer Biomet Dental customers access to Invisalign clear aligners through the iTero platform to facilitate a comprehensive interdisciplinary treatment approach.

3. Patient Demand & Conversion. Our goal is to make Invisalign a highly recognized name brand worldwide by creating awareness for Invisalign treatment among consumers and motivating potential patients to seek Invisalign
treatment. We accomplish this objective through an integrated consumer marketing strategy that includes television, media, social networking and event marketing and strategic alliances with professional sports teams as well as
educating  patients  on  treatment  options  and  directing  them  to  high  volume  Invisalign  doctors.  In  January  2019,  we  expanded  our  Smile  Concierge  program  which  educates  consumers  on  the  benefits  of  Invisalign  treatment,
answers  their  questions  and  helps  them  schedule  an  appointment  with  an  Invisalign  doctor.  The  program  simultaneously  helps  doctors  better  engage  with  prospective  customers  through  more  detailed  customer  insights.
Additionally, in August 2019, we significantly increased our investment in consumer marketing in the U.S. The U.S. campaign was launched across all key media channels to over 140 million consumers, combining a robust paid
media strategy across prime broadcast, cable and connected TV channels with paid search and social media.

4. Orthodontist Utilization. We continue to innovate and increase product applicability and predictability to address a wide range of cases, from simple to complex, thereby enabling doctors to confidently treat teenagers and adults
with the Invisalign System. Over the last several years, we launched Invisalign Comprehensive with Mandibular Advancement and Invisalign First. We also continue to make improvements to our Invisalign treatment software,
ClinCheck Pro, designed to deliver an exceptional user experience and increase treatment control to help our doctors achieve their treatment goals.

Manufacturing and Suppliers

We have manufacturing facilities located in Juarez, Mexico, where we conduct our aligner fabrication, distribution, repair of our iTero scanners and perform our CAD/CAM services. In the fourth quarter of 2018, we also began
fabricating our aligners in Ziyang, China, our first aligner fabrication facility outside of Juarez, Mexico. In addition, we produce our handheld intraoral scanner wand, perform final scanner assembly and repair our scanners at our facilities
in Or Yehuda, Israel and Ziyang, China. Our Invisalign digital treatment planning and interpretation for iTero restorative cases are conducted at our facilities located in San Jose, Costa Rica, Chengdu, China, Cologne, Germany, Madrid,
Spain,  Wroclaw,  Poland  and  Yokohama,  Japan.  Information  regarding  risks  associated  with  our  manufacturing  process  and  foreign  operations  may  be  found  in  Item 1A  of  this  Annual  Report  on  Form  10-K  under  the  heading “Risk
Factors.”

Our quality system is required to be in compliance with the Quality System regulations enforced by the FDA, and similar regulations enforced by other worldwide regulatory authorities. We are certified to EN ISO 13485:2003, an
internationally recognized standard for medical device manufacturing. We have a formal, documented quality system by which quality objectives are defined, understood and achieved. Systems, processes and procedures are implemented
to ensure high levels of product and service quality. We monitor the effectiveness of the quality system based on internal data and direct customer feedback and strive to continually improve our systems and processes, taking corrective
action, as needed.

Since the manufacturing process of our products requires substantial and varied technical expertise, we believe that our manufacturing capabilities are important to our success. In order to produce our highly customized, highly
precise, medical quality products in volume, we have developed a number of proprietary processes and technologies. These technologies include complex software algorithms and solutions, CT scanning, stereolithography and automated
aligner  fabrication.  To  increase  the  efficiency  of  our  manufacturing  processes,  we  continue  to  focus  our  efforts  on  software  development  and  the  improvement  of  rate-limiting  processes  or  bottlenecks.  We  continuously  upgrade  our
proprietary, three-dimensional treatment planning software to enhance computer analysis of treatment data and to reduce time spent on manual and judgmental tasks for each case, thereby increasing the efficiency of our technicians. In
addition, to improve efficiency and increase the scale of our operations, we continue to invest in the development of automated systems for the fabrication and packaging of aligners.

We are highly dependent on manufacturers of specialized scanning equipment, rapid prototyping machines, resin and other advanced materials for our aligners, as well as the optics, electronic and other mechanical components of our
intraoral scanners. We maintain single supply relationships for many of these machines and materials technologies. In particular, our CT scanning and stereolithography equipment used in our aligner manufacturing and many of the critical
components for the optics of our intraoral scanners are provided by single suppliers. We are also committed to purchasing all of our resin and polymer, the primary raw materials used in our manufacturing process for clear aligners, from a
single source. The need to replace one of our single source suppliers could cause a disruption in our ability to timely deliver certain of our products or increase costs. For a discussion of the risks of our supply and manufacturing operations,
see Item 1A Risk Factors.

Sales and Marketing

Our sales efforts are focused on increasing adoption and utilization of the Invisalign System by orthodontists and GPs worldwide and integrating the iTero scanner into the doctors practice. The scanner is an important component to
the customer experience and is central to a digital approach as well as overall customer utilization of Invisalign treatments. In each region, we have direct sales and support organizations, which include quota carrying sales representatives,
sales management and sales administration. We also have distribution partners in certain markets. In the EMEA region, we segmented sales and marketing for certain country markets into two separate organizations to serve each customer
segment, orthodontists and GP dentists separately, thereby increasing our focus and effectiveness on GP dentists. We continue to expand in existing markets through targeted investments in sales resources, professional marketing and
education programs, along with consumer marketing in select countries.

We provide training, marketing and clinical support to orthodontists and GPs. As of December 31, 2019, we had approximately 96,000 active Invisalign trained doctors, which we define as having submitted at least one case in the

prior 12 month period.

Research and Development

We are committed to investing in world-class technology development, which we believe is critical to achieving our goal of establishing the Invisalign System as the standard method for treating malocclusion and our intraoral

scanning platform as the preferred scanning protocol for digital scans.

Our research and development activities are directed toward developing the technology innovations that we believe will deliver our next generation of products and platforms. These activities range from accelerating product and

clinical innovation to developing manufacturing process improvements to researching future technologies and products.

In an effort to demonstrate the broad treatment capabilities of the Invisalign System, various clinical case studies and articles have been published that highlight the clinical applicability of Invisalign to malocclusion cases, including

those of severe complexity. We undertake pre-commercialization trials and testing of our technological improvements to the product and manufacturing process.

Intellectual Property

We believe our intellectual property portfolio represents a substantial business advantage. As of December 31, 2019, we had 489 active U.S. patents, 462 active foreign patents, and 559 pending global patent applications. Our active
U.S.  patents  expire  between  2020  and  2039.  When  patents  expire,  we  lose  the  protection  and  competitive  advantages  they  provided  to  us,  which  could  negatively  impact  our  operating  results;  however,  we  continue  to  pursue  further
intellectual property protection through U.S. and foreign patent applications and non-disclosure agreements. We also seek to protect our software, documentation and other written materials under trade secret and copyright laws. We cannot
be certain that patents will be issued as a result of any patent application or that patents that have been issued to us or that may be issued in the future will remain valid and enforceable or sufficient to protect our technology or products. Our
intellectual property rights may not be successfully asserted in the future or may be invalidated, circumvented or challenged. In addition, the laws of various foreign countries do not protect our intellectual property rights to the same extent
as U.S. laws. Our inability to protect our proprietary information could harm our business. Information

9

regarding risks associated with our proprietary technology and our intellectual property rights may be found in Item 1A of this Annual Report on Form 10-K under the heading “Risk Factors.”

Seasonal Fluctuations

General  economic  conditions  impact  our  business  and  financial  results,  and  we  experience  seasonal  trends  within  our  two  operating  segments,  customer  channels  and  the  geographic  locations  that  we  serve.  Sales  of  Invisalign
treatments are often weaker in Europe during the summer months due to our customers and their patients being on holiday and seasonally higher in China during the third quarter, particularly related to increased teen cases. Similarly, other
international holidays like Chinese New Year can also negatively impact our sales in APAC. In North America, summer is typically the busiest season for orthodontists with practices that have a high percentage of adolescent and teenage
patients as many parents want to get their teenagers started in treatment before the start of the school year; however, many GPs are on vacation during this time and therefore tend to start fewer cases. For our Scanner segment, capital
equipment sales are often stronger in the fourth calendar quarter. Consequently, these seasonal trends have caused and may continue to cause fluctuations in our quarterly results, including fluctuations in sequential revenue growth rates.

Backlog

All Invisalign treatments are individually unique and prescribed by a doctor so, no two cases are alike. The period from which a treatment data package (or a "case”) is received until the acceptance of the digital ClinCheck treatment
plan  is  dependent  on  the  dental  professional’s  discretion  to  modify,  accept  or  cancel  the  treatment  plan. Therefore,  we  consider  the  case  a  firm  order  to  manufacture  aligners  once  the  dental  professional  has  approved  the  ClinCheck
treatment plan. Our Invisalign backlog consists of ClinCheck treatment plans that have been accepted but not yet shipped. Because aligners are shipped shortly after the ClinCheck treatment plan has been accepted, we believe that backlog
is not a good indicator of future clear aligner revenues. Our quarterly clear aligner revenues can be impacted by the timing of the ClinCheck treatment plan acceptances and our ability to ship those cases in the same quarter. We define our
iTero  scanner  backlog  as  orders  where  credit  and  financing  are  generally  approved  and  payment  is  reasonably  assured  but  the  scanner  has  not  yet  shipped.  Our  Invisalign  and  iTero  scanner  backlogs  as  of  December  31,  2019  were
immaterial.

Competition

Currently, our products compete directly against traditional metal brackets and wires and increasingly against products manufactured and distributed by various companies, both within and outside the U.S. Although the number of
competitors varies by segment, geography and customer, we encounter a wide variety of competitors, including new and well-established regional competitors in certain foreign markets, as well as larger companies or divisions of larger
companies with substantial sales, marketing, research and financial capabilities. Due in part to the expiration of certain of our key patents beginning in 2017, we are facing increased competition in the clear aligner market. In addition,
corresponding foreign patents began expiring in 2018 which has increased competition in markets outside the U.S. These competitors include existing larger companies in certain markets who have the ability to leverage their existing
channels in the dental market to compete directly with us, direct-to-consumer (“DTC”) companies that provide clear aligners using a remote teledentistry model requiring little or no in-office care from trained and licensed physicians, and
doctors themselves who can manufacture custom aligners in their offices using modern 3D printing technology. Unlike our DTC competitors, we are committed to a doctor as the core of everything we do, and Invisalign Treatment requires
a doctor's prescription and an in-person physical examination of the patient’s dentition before treatment can begin. Information regarding risks associated with increased competition may be found in Item 1A of this Annual Report on
Form 10-K under the heading “Risk Factors.”

Key competitive factors include:

•

We believe that our products compare favorably with our competitors’ products with respect to each of these factors.

Government Regulation

Many countries throughout the world have established regulatory framework for commercialization of medical devices. As a designer, manufacturer, and marketer of medical devices, we are obligated to comply with the respective
framework of these countries to obtain and maintain access to these global markets. The framework often defines requirements for premarket authorizations which vary from country to country. Failure to obtain appropriate premarket
authorization and to meet all local requirements including specific safety standards in any country in which we currently market our products could cause commercial disruption and/or subject us to sanctions and fines. Delays in receipt of,
or a failure to receive, such premarket authorizations, or the loss of any previously received premarket authorizations, could have a material adverse effect on our business, financial condition, and results of operations.

With regards to premarket authorization in the U.S., our products are classified as medical devices under the U.S. Food, Drug, and Cosmetic Act ("FD&C Act"). The FD&C Act requires these products, when sold in the U.S., to be
safe and effective for their intended use and to comply with medical device regulations defined by the FDA. This regulatory framework is comparable to the framework established in the European Union ("EU"). Within the EU, our
products are subject to the requirements defined by the Medical Device Directive which is generally consistent with FDA regulations.

We believe we are in compliance with all state, federal, and international regulatory requirements that are applicable to our products.

We are also subject to various laws inside and outside the U.S. concerning our relationships with healthcare professionals and government officials, price reporting and regulation, the promotion, sales and marketing of our products
and services, the importation and exportation of our products, the operation of our facilities and distribution of our products. As a global company, we are subject to varying degrees of government regulation in the various countries in
which we do business, and the general trend is toward increasingly stringent oversight and enforcement. Initiatives sponsored by government agencies, legislative bodies, and the private sector to limit the growth of healthcare expenses
generally are ongoing in markets where we do business. It is not possible to predict at this time the long-term impact of such cost containment measures on our future business.

Our customers are healthcare providers that may be reimbursed by federal funded programs such as Medicaid or a foreign national healthcare program, each of which may offer some degree of oversight. Many government agencies,
both domestic and foreign, have increased their enforcement activities with respect to healthcare providers and companies in recent years. Enforcement actions and associated defense can be expensive, and any resulting findings carry the
risk of significant civil and criminal penalties.

In addition, we must comply with numerous data protection requirements that span from individual state and national laws in the U.S. to multinational requirements in the EU. In the U.S., final regulations implementing amendments
to the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) became effective in the latter part of 2013 with the HIPAA Omnibus Rule. We are also required to be in compliance with the California Consumer Privacy Act
(“CCPA”), which went into effect in January 2020. In the EU, we must comply with the General Data Protection Regulation (“GDPR”), which serves as a harmonization of European data-privacy laws. Further expansion into LATAM
markets will require us to prepare for Brazil's Lei Geral de Proteção de Dados ("LGPD") scheduled to take effect in August 2020. Meanwhile, the APAC and EMEA regions have also seen rapid development of privacy laws including
India, Russia, China, South Korea, Singapore, Hong Kong, and Australia.

We believe we have designed our product and service offerings to be compliant with the requirements of applicable data protection laws and regulations. Maintaining systems that are compliant with these laws and regulations is
costly and could require complex changes in the way we do business or provide services to our customers and their patients. Additionally, our success may be dependent on the success of healthcare providers in managing data protection
requirements. Information regarding risks associated with data security and privacy may be found in Item 1A of this Annual Report on Form 10-K under the heading “Risk Factors.”

Employees

As of December 31, 2019,  we  had  approximately  14,530  employees,  including  9,470  in  manufacturing  and  operations,  2,880  in  sales  and  marketing  which  includes  customer  care,  800  in  research  and  development  and  1,380  in

general and administrative functions.

RISK FACTORS

The following discussion is divided into two sections. The first, entitled “Risks Relating to our Business,” discusses some of the risks that may affect our business, results of operations and financial condition. The second, captioned
"Risks Related to our Common Stock," discusses some of the risks relating to owning our common stock. You should carefully review both sections, as well as our consolidated financial statements and notes thereto and other information
appearing in this Annual Report on Form 10-K, for important information regarding these and other risks that may affect us. The fact we have chosen to list one section before the other or that we have identified risks in either section
earlier than others should not be interpreted to mean we deem any risks to be more or less important or more likely to occur than others or, if any do occur, that their impact may be any less significant than others. These risk factors should
be considered in connection with evaluating the forward-looking statements contained in this report because they could cause our actual results and conditions to differ materially from those statements. Before you invest in Align, you
should know that investing involves risks, including those described below. The risks below are not the only ones we face. If any of the risks actually occur, our business, financial condition and results of operations could be negatively
affected, the trading price of our common stock could decline, and you may lose all or part of your investment.

Risks Relating to our Business

Our net revenues are dependent primarily on our Invisalign System and iTero Scanners and any decline in sales or average selling price of these products for any reason, would adversely affect net revenues, gross margin and

net income.

Our net revenues are largely dependent on the sales of our Invisalign System of clear aligners and iTero intraoral scanners. Of the two, we expect net revenues from the sale of the Invisalign System, primarily our comprehensive
products, will continue to account for the vast majority of our net revenues for the foreseeable future. Continued and widespread acceptance of the Invisalign System by orthodontists, GPs and consumers is critical to our future success. Our
iTero scanners are used by dental professionals for restorative and orthodontic procedures as well as Invisalign System case submissions. Sales of our iTero scanners are continuing to grow, becoming a larger percentage of our overall
revenues and as a means to further adoption of digital dentistry and the Invisalign System. If orthodontists and GPs experience a reduction in consumer demand for orthodontic services, if consumers prove unwilling to adopt Invisalign
System treatment as rapidly or in the volumes we anticipate and at the prices offered, if orthodontists or GPs choose to use wires and brackets or competitive products rather than Invisalign, if sales of our iTero scanners decline or fail to
grow sufficiently or as expected, or if the average selling price of our products decline for any reason, particularly in the case of our Invisalign System as a result of a shift in product mix towards lower priced products or as a result of
promotions, or competition, our operating results would be harmed.

Competition in the markets for our products is increasing and we expect aggressive competition from existing competitors and other companies that may introduce new technologies in the future.

The dental industry is in a period of immense and rapid transformation involving products, technologies, distribution channels and business models, much of which is based on digital transformation involving information technology,
data, artificial intelligence, scanning, 3D printing, software and algorithms. While our clear aligner and iTero scanners facilitate this transition, there remains significant uncertainty concerning the technologies that will achieve market
acceptance and, if adopted, whether and when they may become obsolete as new offerings become available.

Currently,  our  clear  aligner  products  compete  directly  against  traditional  metal  brackets  and  wires  and  increasingly  against  clear  aligner  products  manufactured  and  distributed  by  new  market  entrants  as  well  as  traditional
manufacturers of wires and brackets, both within and outside the U.S., and from traditional medical device companies, laboratories, startups and, in some cases, from doctors themselves. Although the number and type of competitors varies
by segment, geography and customer, we encounter a wide variety of competitors, including new and well-established regional competitors in certain foreign markets, as well as larger companies or divisions of larger companies with
substantial sales, marketing, research and financial capabilities. Due in part to the expiration of certain of our key patents beginning in 2017, we have faced increased competition in the clear aligner market. These competitors include
existing larger companies in certain markets who have the ability to leverage their existing channels in the dental market to compete directly with us, direct-to-consumer (“DTC”) companies that provide clear aligners using a remote
teledentistry model that requires little or no in-office care from trained and licensed physicians, and doctors themselves who can manufacture custom aligners in their offices using modern 3D printing technology. In addition, corresponding
foreign patents began expiring in 2018 which has resulted in increased competition in markets outside the U.S. Large consumer product companies may also enter the orthodontic supply market.

The manipulation and movement of teeth and bone is a delicate process with potentially painful and debilitating results if not appropriately performed and monitored. Accordingly, we remain committed to delivering our solutions
primarily through trained and skilled doctors. Invisalign Treatment requires a doctor's prescription and an in person physical examination of the patient’s dentition before beginning treatment. However, with the advent of DTC providers
accompanied by significant advertising

14

campaigns, there has been some shifting away from traditional practices that may impact our primary selling channels. We also believe doctors are sampling alternative products and/or taking advantage of wires and brackets bundles that
essentially give clear aligners away for free or at reduced prices. In addition, we may also face competition in the future from new companies that may introduce new technologies. We may be unable to compete with these competitors or
one or more of these competitors may render our technology obsolete or economically unattractive. If we are unable to compete effectively with existing products or respond effectively to any new technologies, our business could be
harmed.  Increased  competition  has  resulted  in  the  past  and  may  in  the  future  result  in  volume  discounting  and  price  reductions,  reduced  gross  margins  and  profitability,  loss  of  market  share,  and  result  in  the  reduction  of  dental
professionals’ efforts and commitment to use our products, any of which could materially adversely affect our net revenues, volume growth, net income and stock price. We cannot assure that we will be able to compete successfully against
our current or future competitors or that competitive pressures will not have a material adverse effect on our business, results of operations and financial condition.

We are dependent on our international operations, which exposes us to foreign operational, political and other risks that may harm our business.

Our key production steps are performed in operations located outside of the U.S. Technicians use a sophisticated, internally developed computer-modeling program to prepare digital clinical treatment plans (“ClinCheck”), which are
then transmitted electronically to our aligner fabrication facilities. These digital files form the basis of the ClinCheck treatment plan and are used to manufacture aligner molds and aligners. Our digital treatment planning and aligner
fabrication are performed in multiple international locations and we are continuing to establish these functions closer to our international customers to improve doctor and patient experiences and our operational efficiency. Also, in addition
to research and development efforts conducted in the U.S., Russia and Israel, we have operations in Israel and China where we assemble wands, and our intraoral scanner is manufactured. Our reliance on international operations exposes us
to risks and uncertainties that may affect our business or results of operation, including:

difficulties in hiring and retaining employees generally, as well as difficulties in hiring and retaining employees with the necessary skills to perform the more technical aspects of our operations;
difficulties in managing international operations, including any travel restrictions on us or our customers such as those recently imposed in China in response to the Novel Coronavirus epidemic;
fluctuations in currency exchange rates;
import and export controls, license requirements and restrictions;
controlling production volume and quality of the manufacturing process;
political, social and economic instability, including increased levels of violence in Juarez, Mexico, Hong Kong or the Middle East. We cannot predict the effect on us of any future armed conflict, political instability or violence in
these regions. In addition, some of our employees in Israel are obligated to perform annual reserve duty in the Israeli military and may be called for additional active duty under emergency circumstances. We cannot predict the full
impact of these conditions on us, particularly if emergency circumstances or an escalation in political situations occur. If many of our employees are called for active duty, our operations in Israel and our business may not be able
to function at full capacity;
acts of terrorism and acts of war;
general geopolitical instability and the responses to it, such as the possibility of sanctions, trade restrictions and changes in tariffs, including recent sanctions against China and Russia and tariffs imposed by the U.S. and China and
the possibility of additional tariffs or other trade restrictions between the U.S. and Mexico;
interruptions and limitations in telecommunication services;
product or material transportation delays or disruption, including as a result of customs clearance, violence, protests, police and military actions, or as a result of natural disasters, such as earthquakes or volcanic eruptions;
burdens of complying with a wide variety of regional and local laws, including competition and anti-bribery laws;
the impact of government-led initiatives to encourage the purchase or support of domestic vendors, which can affect the willingness of customers to purchase products from, or collaborate to promote interoperability of products
with, companies whose headquarters or primarily operations are not domestic;
unexpected issues and expenses related to our corporate structure reorganization;
reduced intellectual property rights protections as compared to the U.S;
longer payment cycles and greater difficulty in accounts receivable collection; and
potential adverse tax consequences.

The United Kingdom’s (“U.K.”) withdrawal from the EU on January 31, 2020, commonly known as “Brexit,” has exacerbated and may further exacerbate many of the risks and uncertainties described above. The withdrawal of the
U.K. from the EU could, among other potential outcomes, adversely affect the tax, tax treaty, currency, operational, legal and regulatory regimes to which our businesses in the region are subject. The withdrawal could also, among other
potential outcomes, disrupt the free movement of goods, services and people between the U.K. and the EU and significantly disrupt trade between the U.K. and the EU and other parties. Further, uncertainty around these and related issues
could lead to adverse effects on the economy of the U.K., EU and the

15

other economies in which we operate. As the withdrawal continues to unfold, the actual implications of Brexit in their entirety are unlikely to be known for years.

If any of the risks outlined above materialize in the future, we could experience production delays and lost or delayed revenues.

We earn an increasingly larger portion of our total revenues from international sales and face risks attendant to those operations.

We earn an increasingly larger portion of our total revenues from international sales generated through our foreign direct and indirect operations. Since our growth strategy depends in part on our ability to penetrate international
markets and increase the localization of our products and services, we expect to continue to increase our sales and presence outside the U.S., particularly in markets we believe to have high-growth potential. Our international operations are
subject to risks that are customarily encountered in non-U.S. operations, including:

•
•

•
•
•

local political and economic instability;
the engagement of activities by our employees, contractors, partners and agents, especially in countries with developing economies, that are prohibited by international and local trade and labor laws and other laws prohibiting
corrupt payments to government officials, including the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act of 2010 and export control laws, in spite of our policies and procedures designed to ensure compliance with these
laws;
fluctuations in currency exchange rates;
increased expense of developing, testing and making localized versions of our products; and
health pandemics such as the new coronavirus in China and natural disasters including weather and fires such as those common in California and recently in Australia.

Any of these factors, either individually or in combination, could materially impact our international operations and adversely affect our business as a whole.

Demand for our products may not increase as rapidly as we anticipate due to a variety of factors including a weakness in general economic conditions and resistance to non-traditional treatment methods.

Consumer  spending  habits  are  affected  by,  among  other  things,  prevailing  economic  conditions,  levels  of  employment,  salaries  and  wage  rates,  consumer  confidence  and  consumer  perception  of  economic  conditions. A  general
slowdown  in  the  U.S.  economy  and  certain  international  economies  or  an  uncertain  economic  outlook  would  adversely  affect  consumer  spending  habits  which  may,  among  other  things,  result  in  a  decrease  in  the  number  of  overall
orthodontic case starts, reduced patient traffic in dentists’ offices, reduction in consumer spending on elective, non-urgent, or higher value procedures or a reduction in the demand for dental services generally, each of which would have a
material adverse effect on our sales and operating results. Weakness in the global economy results in a challenging environment for selling dental technologies and dentists may postpone investments in capital equipment, such as intraoral
scanners. In addition, Invisalign treatment, which currently accounts for the vast majority of our net revenues, represents a significant change from traditional orthodontic treatment involving metal brackets and wires, and customers and
consumers may be reluctant to accept it, or may not find it cost-effective or preferable to traditional treatment. We have generally received positive feedback from orthodontists, GPs and consumers regarding Invisalign treatment as both an
alternative to braces and as a clinical method for the treatment of malocclusion, but a number of dental professionals believe that the Invisalign treatment is appropriate for only a limited percentage of their patients. Increased market
acceptance of all of our products will depend in part upon the recommendations of dental professionals, as well as other factors including effectiveness, safety, ease of use, reliability, aesthetics, and price compared to competing products
and treatment methods.

Our success may depend on our ability to develop, successfully introduce and achieve market acceptance of new products or product offerings.

Our success depends on our ability to profitably develop, manufacture, market and obtain regulatory approval or clearance of new products and improvements to existing products. There is no assurance we can successfully develop,
sell and achieve market acceptance of new or improved products and services. The extent of, and rate at which, market acceptance and penetration are achieved by new or future products or offerings is a function of many variables, which
include, among other things, our ability to:

•
•
•
•

correctly predict, timely develop and cost effectively manufacture or bring to market solutions that meet future customer needs and preferences with the features and functionality they desire or expect;
allocate our research and development funding to products with higher growth prospects;
ensure compatibility of our computer operating systems and hardware configurations with those of our customers;
anticipate and rapidly respond to new competitive products, product offerings and technological innovations;

16

•
•
•
•
•

differentiate our products and product offerings from our competitors as well as other products in our own portfolio and successfully articulate the benefits of those differences to our customers;
innovate and develop new technologies and applications;
the availability of third-party reimbursement of procedures using our products;
obtain and protect adequate intellectual property rights; and
encourage customers to adopt new technologies.

If we fail to accurately predict customer needs and preferences or fail to produce viable technologies, we may invest heavily in research and development of products that do not lead to significant revenues. Even if we successfully
innovate and develop new products and product enhancements, we may incur substantial costs in doing so and our profitability may suffer. In addition, even if our new products are successfully introduced, it may be difficult to gain market
share and acceptance, particularly if doctors require education to understand the benefits of the new products or measure their success only after extended periods of time required to treat patients. For instance, it can take up to 24 months or
longer  to  treat  patients  using  our  Invisalign  System.  Similarly,  we  recently  introduced  our  mandibular  advancement  treatment  and  expect  it  will  require  significant  time  and  effort  on  our  part  to  educate  doctors  to  the  benefits  of  this
treatment method. Consequently, doctors may be unwilling to rapidly adopt our new products until they successfully complete at least one case or until more historical clinical results are available.

Our ability to market and sell new products may also be subject to government regulation, including approval or clearance by the FDA and foreign government agencies. Any failure in our ability to successfully develop and introduce

or achieve market acceptance of our new products or enhanced versions of existing products could have a material adverse effect on our operating results and could cause our net revenues to decline.

We may experience declines in average selling prices of our products which may decrease our net revenues.

We  provide  volume-based  discount  programs  to  our  customers.  In  addition,  we  sell  a  number  of  products  at  different  list  prices  which  also  differ  based  on  regions  and  or  country.  If  we  change  volume-based  discount  programs
affecting our average selling prices; if we introduce any price reductions or consumer rebate programs; if we expand our discount programs or participation in these programs increases; if our critical accounting estimates materially differ
from  actual  behavior  or  results;  or  if  our  geographic,  channel,  or  product  mix  shifts  to  lower  priced  products  or  to  products  that  have  a  higher  percentage  of  deferred  revenue,  our  average  selling  prices  would  be  adversely  affected.
Moreover, we may find that some programs are unsuccessful or, even if successful may drive demand in unexpected ways. Were any of the foregoing to occur, our net revenues, gross profit, gross margin and net income may be reduced.

We are exposed to fluctuations in currency exchange rates, which could negatively affect our financial condition and results of operations.

Although the U.S. dollar is our reporting currency, a growing portion of our net revenues and net income are generated in foreign currencies. Net revenues and net income generated by subsidiaries operating outside of the U.S. are
translated into U.S. dollars using constantly fluctuating, often substantially, exchange rates during the respective period. As a result, negative movements in exchange rates against the U.S. dollar have and may increasingly adversely affect
our net revenues and net income in our consolidated financial statements. We enter into currency forward contract transactions in an effort to cover some of our exposure to currency fluctuations but there is no assurance these transactions
will fully or effectively hedge our exposure to currency fluctuations, and, under certain circumstances, these transactions could have an adverse effect on our financial condition.

As we continue to grow, we are subject to growth related risks, including risks related to excess or constrained capacity and operational inefficiencies at our manufacturing and treat facilities.

We are subject to growth related risks, including excess or constrained capacity and pressure on our internal systems and personnel. In order to manage current operations and future growth effectively, we will need to continue to
implement and improve our operational, financial and management information systems and to hire, train, motivate, manage and retain employees. We may be unable to manage such growth effectively. Any such failure could have a
material adverse impact on our business, operations and prospects. We continue to establish additional order acquisition, treatment planning and manufacturing facilities closer to our international customers in order to provide doctors with
a  better  experience,  improve  their  confidence  in  using  Invisalign  to  treat  more  patients,  more  often  and  provide  redundancy  should  other  facilities  be  temporarily  or  permanently  unavailable.  Our  ability  to  plan,  construct  and  equip
additional order acquisition, treatment planning and manufacturing facilities is subject to significant risk and uncertainty, including risks inherent in the establishment of a facility, such as hiring and retaining employees and delays and cost
overruns as a result of a number of factors, any of which may be out of our control and may negatively impact our gross margin. In addition, these facilities may be located in higher cost regions compared to Mexico and Costa Rica, which
may negatively impact our gross margin. If the transition into additional facilities is significantly delayed or demand for our products exceeds our current expectations, we may be unable to fulfill orders timely, which may negatively
impact our financial results, reputation and

17

overall business. In addition, because we cannot immediately adapt our production capacity and related cost structures to changing market conditions, our facility capacity may at times exceed or fall short of our production requirements. If
product demand decreases or we fail to forecast demand accurately, we could be required to write off inventory or record excess capacity charges, which would lower our gross margin. Production of our intraoral scanners may also be
limited by capacity constraints due to a variety of factors, including our dependency on third party vendors for key components in addition to limited production yields. Any or all of these problems could result in the loss of customers,
provide an opportunity for competing products to gain market acceptance and otherwise harm our business and financial results.

If we fail to sustain or increase profitability or revenue growth in future periods, our profitability may decline.

If we are to sustain or increase profitability in future periods, we need to continue increasing our net revenues, while controlling expenses. Because our business is evolving, it is difficult to predict our future operating results or levels

of growth, and we have not in the past and may be unable in the future to sustain our historical growth rates which may cause our profitability to decline.

Our operating results have fluctuated in the past and may fluctuate in the future, making it difficult to predict the timing and amount of revenues, costs and expenditures.

Our  operating  results  have  fluctuated  in  the  past  and  we  expect  our  future  quarterly  and  annual  operating  results  to  fluctuate  for  a  variety  of  reasons,  particularly  as  we  focus  on  increasing  doctor  and  consumer  demand  for  our

products.  Some of the factors that could cause our operating results to fluctuate include:

•
•
•
•
•
•
•
•
•

limited visibility into and difficulty predicting from quarter to quarter, the level of activity in our customers’ practices;
changes in geographic, channel, or product mix;

•
•
• weakness in consumer spending as a result of a slowdown in the global, U.S. or other economies;
•
•
•
•

higher manufacturing costs;
competition in general and competitive developments in the market;
changes in relationships with our dental support organizations and distributors, including timing of orders;
changes in the timing of when revenues are recognized, including as a result of the timing of receipt of product orders and shipments, the introduction of new products and software releases, product offerings or promotions,
modifications to our terms and conditions or as a result of new accounting pronouncements or changes to critical accounting estimates including, without limitation, those estimates based on such matters as our predicted usage of
additional aligners;
fluctuations in currency exchange rates against the U.S. dollar;
our inability to scale, suspend or reduce production based on variations in product demand;
increased participation in our customer rebate or discount programs could adversely affect our average selling prices;
seasonal fluctuations, including those related to patient demographics such as teen buying habits in China and Europe as well as the number of doctors in their offices and their availability to take appointments;
success of or changes to our marketing programs from quarter to quarter;
our reliance on our contract manufacturers for the production of sub-assemblies for our intraoral scanners;
increased advertising or marketing efforts or aggressive price competition from competitors;
changes to our effective tax rate;
unanticipated delays and disruptions in the manufacturing process caused by insufficient capacity or availability of raw materials, turnover in the labor force or the introduction of new production processes, power outages or
natural or other disasters beyond our control;
underutilization of manufacturing and treat facilities;

•
• major changes in available technology or the preferences of customers may cause our current product offerings to become less competitive or obsolete;
•
•
•
•
•

costs and expenditures in connection with litigation;
costs and expenditures in connection with the establishment of treatment planning and fabrication facilities in international locations;
costs and expenditures in connection with hiring and deployment of direct sales force personnel;
unanticipated delays in our receipt of patient records made through intraoral scanners for any reason;
disruptions to our business due to political, economic or other social instability or any governmental regulatory or similar actions, including the impact of an epidemic such as recent developments beginning in China in connection
with the Novel Coronavirus, any of which results in changes in consumer spending habits, consumers unable or unwilling to visit the orthodontist or general practitioners office, as well as any impact on workforce absenteeism;
inaccurate forecasting of net revenues, production and other operating costs;
investments in research and development to develop new products and enhancements;

•
•
• material impairments in the value of our privately held companies; and
•

timing of industry tradeshows.

18

To respond to these and other factors, we may make business decisions that adversely affect our operating results such as modifications to our pricing policy, promotions, development efforts, product releases, business structure or
operations. Most of our expenses, such as employee compensation and lease payment obligations, are relatively fixed in the short term. Moreover, our expense levels are based, in part, on our expectations regarding future revenue levels.
As a result, if our net revenues for a particular period fall below expectations, we may be unable to adjust spending quickly enough to offset any shortfall in net revenues. Due to these and other factors, we believe that quarter-to-quarter
comparisons of our operating results may not be meaningful. You should not rely on our results for any one quarter as an indication of our future performance.

A disruption in the operations of our primary freight carrier or higher shipping costs could cause a decline in our net revenues or a reduction in our earnings.

We are dependent on commercial freight carriers, primarily UPS, to deliver our products. If the operations of these carriers are disrupted for any reason, we may be unable to timely deliver our products to our customers. If we cannot
deliver our products on time and cost effectively, our customers may choose competitive offerings or create their own aligners causing our net revenues and gross margins to decline, possibly materially. In a rising fuel cost environment,
our freight costs will increase. In addition, we earn an increasingly larger portion of our total revenues from international sales. International sales carry higher shipping costs which could negatively impact our gross margin and results of
operations. If freight costs materially increase and we are unable to pass that increase along to our customers for any reason or otherwise offset such increases in our cost of net revenues, our gross margin and financial results could be
adversely affected.

 If we are unable to accurately predict our volume growth and fail to hire a sufficient number of technicians in advance of such demand, or hire technicians faster than our actual growth projections, the delivery time of our

products could be delayed or our costs may exceed our revenues, each of which could adversely affect our results of operations.

Treatment planning is a key step leading to our manufacturing process which relies on sophisticated computer software. This requires new technicians to undergo a relatively long training process, often up to 120 days or longer. As a
result, if we are unable to accurately predict our volume growth, we may have an insufficient number of trained technicians to deliver our products within the time frame our customers expect. Such a delay could cause us to lose existing
customers or fail to attract new customers. This could cause a decline in our net revenues and net income and could adversely affect our results of operations. Conversely, if we hire and train technicians in anticipation of volume growth
that does not materialize or materializes at a rate we do not anticipate, our costs and expenditures may outpace our revenue growth, harming our gross margins, operating expenses and financial results.

Our information technology systems are critical to our business. System integration and implementation issues and system security risks could disrupt our operations, which could have a material adverse impact on our business

and operating results.

We rely on the efficient and uninterrupted operation of complex information technology systems. All information technology systems are vulnerable to damage or interruption from a variety of sources. As our business has grown in
size and complexity, the growth has placed, and will continue to place significant demands on such systems. To effectively manage this growth, our information systems and applications require an ongoing commitment of significant
resources  to  maintain,  protect  and  enhance  existing  systems  and  develop  new  systems  to  keep  pace  with  continuing  changes  in  information  processing  technology,  evolving  industry  and  regulatory  standards  and  changing  customer
preferences. We are continuing to transform certain business processes, extend established processes to new subsidiaries and/or implement additional functionality in our enterprise resource planning (“ERP”) software system which entails
certain risks, including difficulties with changes in business processes that could disrupt our operations, such as our ability to track orders and timely ship products, manage our supply chain and aggregate financial and operational data.

System upgrades and enhancements require significant expenditures and allocation of valuable employee resources. Delays in integration or disruptions to our business from implementation of these new or upgraded systems could

have a material adverse impact on our financial condition and operating results.

Additionally,  we  continuously  upgrade  our  customer  facing  software  applications,  specifically  the  ClinCheck  software,  MyAligntech  and  the  Invisalign  Doctor  Site.  Software  applications  frequently  contain  errors  or  defects,
especially when they are first introduced or when new versions are released. The discovery of a defect or error in our software applications or information systems, or incompatibility with customers’ computer operating systems and
hardware configurations with a new release or upgraded version or the failure of our primary information systems may result in the following consequences, among others: delay or loss of revenues or delay in market acceptance, damage to
our reputation, loss of market share to competition or increased service costs, any of which could have a material adverse effect on our business, financial condition or results of operations.

 If the information we rely on to run our businesses were to be found to be inaccurate or unreliable, if we fail to properly maintain our information systems and data integrity, or if we fail to develop new capabilities to meet our

business needs in a timely

19

manner, we could suffer operational disruptions, have customer disputes, fail to produce timely and accurate reports, have regulatory or other legal problems, experience increases in operating and administrative expenses, lose existing
customers, have difficulty in attracting new customers or in implementing our growth strategies, or suffer other adverse consequences. In addition, experienced computer programmers and hackers may be able to penetrate our network
security or our cloud-based software servers hosted by third parties and misappropriate our confidential information or that of third parties, create system disruptions or cause shutdowns. Furthermore, sophisticated hardware and operating
system software and applications that we either internally develop or procure from third parties may contain defects in design and manufacture, including “bugs” and other problems that can unexpectedly interfere with the operation of the
system. The costs to eliminate or alleviate security problems, viruses and bugs could be significant, and the efforts to address these problems could result in interruptions that may have a material adverse impact on our operations, net
revenues and operating results.

Furthermore, our business requires the secure transmission of confidential patient health information over public networks. Because we store and transmit sensitive information including protected patient health information, security
breaches could expose us to a risk of regulatory action, litigation, possible liability and loss. We have experienced breaches in the past and our security measures may be inadequate to prevent future security breaches, and our business
operations and profitability would be adversely affected by, among other things, loss of customers and potential criminal and civil sanctions if they are not prevented.

There can be no assurance that our process of improving existing systems, developing new systems to support our expanding operations, integrating new systems, protecting confidential patient health information, and improving
service levels will not be delayed or that additional systems issues will not arise in the future. Failure to adequately protect and maintain the integrity of our information systems and data may result in a material adverse effect on our
financial position, results of operations and cash flows.

If the security of our customer and patient information is compromised or we are unable to comply with data protection laws, patient care could suffer, and we could be liable for related damages, and our reputation could be

impaired.

We retain confidential customer financial as well as patient health information in our processing centers. Therefore, it is critical that our facilities and infrastructure remain secure and are also perceived by the marketplace and our
customers to be secure. Despite the implementation of security measures, we have experienced breaches in the past and our infrastructure may be vulnerable to physical break-ins, computer viruses, programming errors or other technical
malfunctions, hacking or phishing attacks by third parties, employee error or malfeasance or similar disruptive problems. If we fail to meet our customer and patients’ expectations regarding the security of customer and patient information,
we could be liable for damages and our reputation and competitive position could be impaired. Affected parties could initiate legal or regulatory action against us, which could cause us to incur significant expense and liability or result in
orders forcing us to modify our business practices. Concerns over our privacy practices could adversely affect others’ perception of us and deter customers, advertisers and partners from using our products. In addition, patient care could
suffer, and we could be liable if our systems fail to deliver correct information in a timely manner. We have cybersecurity insurance related to a breach event covering expenses for notification, credit monitoring, investigation, crisis
management, public relations and legal advice. The policy also provides coverage for regulatory action defense including fines and penalties, potential payment card industry fines and penalties and costs related to cyber extortion; however,
damage and claims arising from such incidents may not be covered or may exceed the amount of any coverage.

We are also subject to federal, state and foreign laws and regulations, including ones relating to privacy, data protection, content regulation, and consumer protection. We may be or become subject to data localization or data residency
laws  which  generally  require  that  certain  types  of  data  collected  within  a  country  be  stored  and  processed  only  within  that  country  or  approved  countries.  Some  countries,  including  Russia  and  China,  have  enacted,  and  others  are
considering enacting, data localization or data residency laws. If countries in which we have customers adopt data localization or data residency laws, we could be required to implement new or expand existing data storage protocols, build
new storage facilities, and/or devote additional resources to comply with the requirements of such laws, any of which could have significant cost implications. We may also be subject to data export restrictions, or international transfer laws
which prohibit or impose conditions upon the transfer of such data from one country to another. These laws and regulations are constantly evolving and may be interpreted, applied, created or amended in a manner that could adversely
affect our business.

In addition, we must comply with numerous data protection requirements that span from individual state and national laws in the U.S. to multinational requirements in the EU. In the EU, we must comply with the General Data
Protection Regulation (“GDPR”) which serves as a harmonization of European data-privacy laws. We believe we have designed our product and service offerings to be compliant with the requirements of applicable data protection laws and
regulations. Maintaining systems that are compliant with these laws and regulations is costly and could require complex changes in the way we do business or provide services to our customers and their patients. Additionally, our success
may be dependent on the success of healthcare providers in managing data protection requirements.

20

In order to deepen our market penetration and raise awareness of our brand and products, we have increased the amount we spend on marketing activities, which may not ultimately prove successful or an effective use of our

resources.

To  increase  awareness  of  our  products  and  services  domestically  and  internationally,  we  have  increased  the  amount  we  spend,  and  anticipate  spending  in  the  future  on  marketing  activities.  Our  marketing  efforts  and  costs  are
significant  and  include  national  and  regional  campaigns  involving  television,  print  media,  social  media  and,  more  recently,  alliances  with  professional  sports  teams  and  other  strategic  partners.  We  attempt  to  structure  our  advertising
campaigns in ways we believe most likely to increase brand awareness and adoption; however, there is no assurance our campaigns will achieve the returns on advertising spend desired or successfully increase brand or product awareness
sufficiently to sustain or increase our growth goals, which could have an adverse effect on our gross margin and business overall.

Our success depends in part on our proprietary technology, and if we are unable to successfully enforce our intellectual property rights, our competitive position may be harmed. Litigating claims of this type is costly and could

distract our management and cause a decline in our results of operations and stock price.

Our success depends in part on our ability to maintain existing intellectual property rights and to obtain and maintain further intellectual property protection for our products, both in the U.S. and in other countries. Our inability to do

so could harm our competitive position. For further details concerning our patents and other intellectual property, please see “Intellectual Property” in Part I, Item 1. Business” of this annual report on Form 10-K.

We intend to rely on our portfolio of issued and pending patent applications in the U.S. and in other countries to protect a large part of our intellectual property and our competitive position; however, our currently pending or future
patent filings may not result in the issuance of patents. Additionally, any patents issued to us may be challenged, invalidated, held unenforceable, circumvented, or may not be sufficiently broad to prevent third parties from producing
competing products similar in design to our products. In addition, any protection afforded by foreign patents may be more limited than that provided under U.S. patents and intellectual property laws. Certain of our key patents began to
expire  in  2017,  which  have  resulted  in  increased  competition  and  less  expensive  competitive  products.  We  also  rely  on  protection  of  our  copyrights,  trade  secrets,  know-how  and  proprietary  information.  We  generally  enter  into
confidentiality agreements with our employees, consultants and our collaborative partners upon commencement of a relationship with us; however, these agreements may not provide meaningful protection against the unauthorized use or
disclosure of our trade secrets or other confidential information, and adequate remedies may not exist if unauthorized use or disclosure were to occur. Our inability to maintain the proprietary nature of our technology through patents,
copyrights or trade secrets would impair our competitive advantages and could have a material adverse effect on our operating results, financial condition and future growth prospects. In particular, a failure to protect our proprietary rights
might allow competitors to copy our technology, which could adversely affect our pricing and market share. In addition, in an effort to protect our intellectual property we are currently, have in the past been, and may in the future be
involved in litigation. The potential effects on our business operations resulting from litigation that we may participate in the future, whether or not ultimately determined in our favor or settled by us, are costly and divert the efforts and
attention of our management and technical personnel from normal business operations.

Litigation, interferences, oppositions, re-exams, inter partes reviews, post grant reviews or other proceedings are, have been and may in the future be necessary in some instances to determine the validity and scope of certain of our
proprietary  rights,  and  in  other  instances  to  determine  the  validity,  scope  or  non-infringement  of  certain  patent  rights  claimed  by  third  parties  to  be  pertinent  to  the  manufacture,  use  or  sale  of  our  products.  Litigation,  interference,
oppositions, re-exams, inter partes reviews, post grant reviews, administrative challenges or other similar types of proceedings are unpredictable and may be protracted, expensive and distracting to management. The outcome of such
proceedings could adversely affect the validity and scope of our patent or other proprietary rights, hinder our ability to manufacture and market our products, require us to seek a license for the infringed product or technology or result in
the assessment of significant monetary damages. An unfavorable ruling could include monetary damages or, in cases where injunctive relief is sought, an injunction prohibiting us from selling our products. Any of these results from our
litigation could adversely affect our results of operations and stock price.

Obtaining approvals and complying with regulations enforced by the FDA and foreign regulatory authorities is an expensive and time-consuming process, and any failure to obtain or maintain approvals for our products or

services or failure to comply with regulations could materially harm our sales, result in substantial penalties and cause harm to our reputation.

Our products are considered medical devices and are subject to extensive and widely varying regulations in the U.S. and internationally. Before we can sell a new medical device in the U.S., or market a new use of or claim for an
existing product, we must obtain FDA clearance or approval unless an exemption applies. Internationally, similar requirements apply on a country by country basis. In the U.S., FDA regulations are wide ranging and govern, among other
things:

•

product design, development, manufacturing and testing;

21

•
•
•
•
•
•

product labeling;
product storage;
pre-market clearance or approval;
complaint handling and corrective actions;
advertising and promotion; and
product sales and distribution.

It takes significant time, effort and expense to obtain and maintain FDA approvals of our products and services. In other countries, the requirements to obtain and maintain similar approvals may differ materially from those of the
FDA. Moreover, there is no guarantee we will successfully obtain or maintain approvals in all or any of the countries in which we do business now or in the future. Even if we are successful, the time and effort may take significantly
longer, and costs may be significantly greater.  If approvals to market our products or services are delayed, whether in the U.S. or other countries, we may be unable to market our products or services in markets we deem important to our
business. Were any of these risks to occur, our domestic or international operations may be materially harmed, and our business as a whole adversely impacted.

In addition, our failure to comply with applicable regulatory requirements could result in enforcement actions in the U.S. and other countries. For example, enforcement actions by the FDA may include any of the following sanctions:

repair, replacement, refunds, recall or seizure of our products;
operating restrictions or partial suspension or total shutdown of production;
refusing our requests for 510(k) clearance or pre-market approval of new products, new intended uses, or modifications to existing products;

• warning letters, fines, injunctions, consent decrees and civil penalties;
•
•
•
• withdrawing clearance or pre-market approvals that have already been granted; and
•

criminal prosecution.

We must also comply with facility registration and product listing requirements of the FDA and adhere to applicable Quality System regulations. The FDA enforces its Quality System regulations through periodic unannounced
inspections. Our failure to take satisfactory corrective action in response to an adverse inspection or the failure to comply with applicable manufacturing regulations could result in enforcement action, and we may be required to find
alternative manufacturers, which could be a long and costly process. Any enforcement action by the FDA or foreign governments could have a material adverse effect on us.

The sourcing and availability of metals used in the manufacture of a limited number of parts (if any) contained in our products may be affected by laws and regulations in the U.S. or internationally regarding the use of minerals
obtained from certain regions of the world like the Democratic Republic of Congo and adjoining countries. These laws and regulations may decrease the number of suppliers capable of supplying our needs for certain metals, thereby
negatively affecting our ability to obtain products in sufficient quantities or at competitive prices. We may furthermore suffer financial and reputational harm if customers require, and we are unable to deliver, certification that our products
are conflict free. Regardless, we will incur additional costs associated with compliance with these laws and regulations, including time-consuming and costly efforts to determine the source of any conflict minerals used in our products.

We are required to annually assess our internal control over financial reporting and any future adverse results from such assessment could result in a loss of investor confidence in our financial reports and have an adverse effect

on our stock price.

We have implemented and routinely assess, update and refine our internal control over financial reporting for its effectiveness. Pursuant to the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated by the SEC, we
are required to furnish in our Form 10-K a report by our management regarding the effectiveness of our internal control over financial reporting. The report includes, among other things, an assessment of the effectiveness of our internal
control over financial reporting as of the end of our fiscal year, including a statement as to whether or not our internal control over financial reporting is effective. This assessment must include disclosure of any material weaknesses in our
internal control over financial reporting identified by management. Our internal controls may become inadequate because of changes in conditions including changes in personnel, updates and upgrades to existing software including our
ERP software system, changes in accounting standards or interpretations of existing standards, and, as a result, the degree of compliance of our internal control over financial reporting with the existing policies or procedures may become
ineffective.  Establishing,  testing  and  maintaining  an  effective  system  of  internal  control  over  financial  reporting  requires  significant  resources  and  time  commitments  on  the  part  of  our  management  and  our  finance  staff,  may  require
additional staffing and infrastructure investments and increases our costs of doing business. If we are unable to assert that our internal control over financial reporting is effective in any future period (or if our auditors are unable to express
an opinion on the effectiveness of our internal controls or conclude that our internal controls are ineffective), the timely filing of our financial reports could be delayed or we could be required to restate past reports, and cause us to lose
investor confidence in the accuracy and completeness

22

of our financial reports in the future, which could have an adverse effect on our stock price.

If we lose our key personnel or are unable to attract and retain key personnel, we may be unable to pursue business opportunities or develop our products.

We  are  highly  dependent  on  the  key  employees  in  our  clinical  engineering,  technology  development,  sales,  training  and  marketing  personnel  and  management  teams. The  loss  of  the  services  provided  by  those  individuals  may
significantly  delay  or  prevent  the  achievement  of  our  product  development  and  other  business  objectives  and  could  harm  our  business.  Our  future  success  will  also  depend  on  our  ability  to  identify,  recruit,  train  and  retain  additional
qualified personnel, including orthodontists and production technicians in our treatment planning facilities. Few orthodontists are accustomed to working in a manufacturing environment since they are generally trained to work in private
practices, universities and other research institutions. Thus, we may be unable to attract and retain personnel with the advanced qualifications necessary for the further development of our business. Furthermore, we may not be successful in
retaining our key personnel or their services. If we are unable to attract and retain key personnel, our business could be materially harmed.

 If we infringe the patents or proprietary rights of other parties or are subject to a patent infringement claim, our ability to grow our business may be severely limited.

Extensive litigation over patents and other intellectual property rights is common in the medical device industry. We have been sued for infringement of third party’s patents in the past and we may be the subject of patent or other
litigation in the future. We periodically receive and may in the future receive letters from third parties drawing our attention to their patent rights. While we do not believe we infringe upon any valid and enforceable rights that have been
brought to our attention, there may be other more pertinent rights of which we are presently unaware. The defense and prosecution of intellectual property suits, interference proceedings and related legal and administrative proceedings
could result in substantial expense to us and significant diversion of effort by our technical and management personnel. An adverse determination of any litigation or interference proceeding to which we may become a party could subject
us  to  significant  liabilities.  An  adverse  determination  of  this  nature  could  also  put  our  patents  at  risk  of  being  invalidated  or  interpreted  narrowly  or  require  us  to  seek  licenses  from  third  parties.  Licenses  may  not  be  available  on
commercially reasonable terms or at all, in which event, our business would be materially adversely affected.

We maintain single supply relationships for certain key machines and materials, and our business and operating results could be harmed if supply is restricted or ends or the price of raw materials used in our manufacturing

process increases.

We  are  highly  dependent  on  manufacturers  of  specialized  scanning  equipment,  rapid  prototyping  machines,  resin  and  other  advanced  materials,  as  well  as  the  optics,  electronic  and  other  mechanical  components  of  our  intraoral
scanners.  We  maintain  single  supply  relationships  for  many  of  these  machines  and  materials  technologies.  In  particular,  our  CT  scanning  and  stereolithography  equipment  used  in  our  aligner  manufacturing  and  many  of  the  critical
components for the optics of our scanners are provided by single suppliers. We are also committed to purchasing the vast majority of our resin and polymer, the primary raw materials used in our manufacturing process for clear aligners,
from a single source. If these or other suppliers encounter financial, operating or other difficulties or if our relationship with them changes, we may be unable to quickly establish or qualify replacement sources of supply and could face
production interruptions, delays and inefficiencies. In addition, technology changes by our vendors could disrupt access to required manufacturing capacity or require expensive, time consuming development efforts to adapt and integrate
new equipment or processes. Our growth may exceed the capacity of one or more of these manufacturers to produce the needed equipment and materials in sufficient quantities to support our growth. Conversely, in order to secure supplies
for production of products, we sometimes enter into non-cancelable minimum purchase commitments with vendors, which could impact our ability to adjust our inventory to reflect declining market demands. If demand for our products is
less than we expect, we may experience additional excess and obsolete inventories and be forced to incur additional charges and our profitability may suffer. In the event of technology changes, delivery delays, or shortages of or increases
in price for these items, our business and growth prospects may be harmed.

We  depend  on  a  single  contract  manufacturer  and  supplier  of  parts  used  in  our  iTero  scanner  and  any  disruption  in  this  relationship  may  cause  us  to  fail  to  meet  the  demands  of  our  customers  and  damage  our  customer

relationships.

We rely on a third-party manufacturer to supply key sub-assemblies for our iTero Element scanner. As a result, if this manufacturer fails to deliver its components, if we lose its services or if we fail to negotiate or maintain acceptable
terms,  we  may  be  unable  to  deliver  our  products  in  a  timely  manner  and  our  business  may  be  harmed.  Furthermore,  any  difficulties  encountered  by  this  manufacturer  with  respect  to  hiring  personnel  and  maintaining  acceptable
manufacturing  standards,  controls,  procedures  and  policies  could  disrupt  our  ability  to  timely  deliver  our  products.  Finding  a  substitute  manufacturer  may  be  expensive,  time-consuming  or  impossible  and  could  result  in  a  significant
interruption  in  the  supply  of  our  intraoral  scanning  products. Any  failure  by  our  contract  manufacturer  that  results  in  delays  in  our  fulfillment  of  customer  orders  may  cause  us  to  lose  revenues  and  suffer  damage  to  our  customer
relationships.

23

We primarily rely on our direct sales force to sell our products, and any failure to train and maintain our direct sales force could harm our business.

Our ability to sell our products and generate revenues primarily depends upon our direct sales force within our Americas and International markets. We do not have any long-term employment contracts with our direct sales force and
the loss of the services provided by these key personnel may harm our business. In order to provide more comprehensive sales and service coverage, we continue to increase the size of our sales force to pursue growth opportunities within
and outside of our existing geographic markets. Moreover, as we focus on market penetration, we have begun to segregate sales personnel to focus on specific markets such as orthodontists and GPs. To adequately train new representatives
to successfully market and sell our products and for them to establish strong customer relationships can take up to twelve months or more. As a result, if we are unable to retain our direct sales personnel or quickly replace them with
individuals of equivalent technical expertise and qualifications, if we are unable to successfully instill technical expertise in new and existing sales representatives, if we fail to establish and maintain strong relationships with our customers,
or if our efforts at specializing our selling techniques do not prove successful and cost-effective, our net revenues and our ability to maintain market share could be materially harmed. In addition, due to our large and fragmented customer
base, we may not be able to provide all of our customers with product support immediately upon the launch of a new product. As a result, adoption of new products by our customers may be slower than anticipated and our ability to grow
market share and increase our net revenues may be harmed.

As compliance with healthcare regulations becomes more costly and difficult for us or our customers, we may be unable to grow our business.

Participants in the healthcare industry are subject to extensive and frequently changing regulations under numerous laws administered by governmental entities at the federal, state and local levels, some of which are, and others of

which may be, applicable to our business.

Furthermore, our healthcare provider customers are also subject to a wide variety of laws and regulations that could affect the nature and scope of their relationships with us. The healthcare market itself is highly regulated and subject
to  changing  political,  economic  and  regulatory  influences.  Regulations  implemented  pursuant  to  the  Health  Insurance  Portability  and  Accountability  Act  (“HIPAA”),  including  regulations  affecting  the  security  and  privacy  of  patient
healthcare information held by healthcare providers and their business associates may require us to make significant and unplanned enhancements of software applications or services, result in delays or cancellations of orders, or result in
the revocation of endorsement of our products and services by healthcare participants. The effect of HIPAA and newly enforced regulations on our business is difficult to predict, and there can be no assurance that we will adequately
address the business risks created by HIPAA and its implementation or that we will be able to take advantage of any resulting business opportunities.

Extensive and changing government regulation of the healthcare industry may be expensive to comply with and exposes us to the risk of substantial government penalties.

In addition to medical device laws and regulations, numerous state and federal healthcare-related laws regulate our business, covering areas such as:

•
•
•

storage, transmission and disclosure of medical information and healthcare records;
prohibitions against the offer, payment or receipt of remuneration to induce referrals to entities providing healthcare services or goods or to induce the order, purchase or recommendation of our products; and
the marketing and advertising of our products.

Complying with these laws and regulations could be expensive and time-consuming and could increase our operating costs or reduce or eliminate certain of our sales and marketing activities or our revenues.

Our business exposes us to potential product liability claims, and we may incur substantial expenses if we are subject to product liability claims or litigation.

Medical devices involve an inherent risk of product liability claims and associated adverse publicity. We may be held liable if any product we develop or any product that uses or incorporates any of our technologies causes injury or is
otherwise found unhealthy or unsuitable. Although we intend to continue to maintain product liability insurance, adequate insurance may not be available on acceptable terms, if at all, and may not provide adequate coverage against
potential liabilities. A product liability claim, regardless of its merit or eventual outcome, could result in significant legal defense costs and damage our reputation. These costs would have the effect of increasing our expenses and diverting
management’s attention away from the operation of our business and could harm our business.

24

Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses.

Our global operations may be disrupted by natural or human induced disasters including, earthquakes, tsunamis, floods, drought, hurricanes, typhoons, wildfires, extreme weather conditions, power shortages, telecommunications
failures, materials scarcity and price volatility, and medical epidemics or health pandemics. Climate change may increase both the frequency and severity of natural disasters and, consequently, risks to our operations and growth. The
occurrence  of  business  disruptions  could  harm  our  growth  and  expansion,  result  in  significant  losses,  seriously  harm  our  revenue,  profitability  and  financial  condition,  adversely  affect  our  competitive  position,  increase  our  costs  and
expenses, and require substantial expenditures and recovery time in order to fully resume operations. Our digital dental modeling is primarily processed in our facility located in San Jose, Costa Rica. The operations team in Costa Rica
creates ClinCheck treatment plans using sophisticated computer software. In addition, our customer facing operations are located in Costa Rica. Our aligner molds and finished aligners are fabricated in Juarez, Mexico and, we have and are
building additional facilities in China. Both locations in Costa Rica and Mexico are in earthquake zones and may be subject to other natural disasters. If there is a major earthquake or any other natural disaster in a region where one of these
facilities is located, our ability to create ClinCheck treatment plans, respond to customer inquiries or manufacture and ship our aligners could be compromised which could result in our customers experiencing significant delays receiving
their aligners and a decrease in service levels for a period of time. Additionally, our sales and operations in China have been impacted and are likely to continue to be disrupted as a result of the Novel Coronavirus outbreak. Moreover, our
corporate headquarters and a portion of our research and development activities are located in California, which suffers from earthquakes, periodic droughts, and wildfires affecting the health and safety of our employees. Any such business
interruptions could materially and adversely affect our business, financial condition and results of operations.

Changes in, or interpretations of, accounting rules and regulations, could result in unfavorable accounting charges.

We prepare our consolidated financial statements in conformity with Generally Accepted Accounting Principles in the U.S. ("GAAP"). These principles are subject to interpretation by the SEC and various bodies formed to interpret
and create appropriate accounting policies. A change in these policies or in the way these policies are interpreted by us or regulators can have a significant effect on our reported results and may even retroactively affect previously reported
transactions.

If we fail to manage our exposure to global financial and securities market risk successfully, our operating results and financial statements could be materially impacted.

The primary objective of our investment activities is to preserve principal. To achieve this objective, a majority of our marketable investments are investment grade, liquid, fixed-income securities and money market instruments
denominated in U.S. dollars. If the carrying value of our investments exceeds the fair value, and the decline in fair value is deemed to be other-than-temporary, we will be required to write down the value of our investments, which could
materially harm our results of operations and financial condition. Moreover, the performance of certain securities in our investment portfolio correlates with the credit condition of the U.S. financial sector. In an unstable credit environment,
we might incur significant realized, unrealized or impairment losses associated with these investments.

If our goodwill or long-lived assets become impaired, we may be required to record a significant charge to earnings.

Under  GAAP,  we  review  our  goodwill  and  long-lived  asset  group  for  impairment  when  events  or  changes  in  circumstances  indicate  the  carrying  value  may  not  be  recoverable.  Additionally,  goodwill  is  required  to  be  tested  for
impairment at least annually. The qualitative and quantitative analysis used to test goodwill are dependent upon various assumptions and reflect management’s best estimates. Changes in certain assumptions including revenue growth rates,
discount rates, earnings multiples and future cash flows may cause a change in circumstances indicating that the carrying value of goodwill or the asset group may be impaired. We may be required to record a significant charge to earnings
in the financial statements during the period in which any impairment of goodwill or asset group are determined.

We may experience unexpected issues and expenses associated with our corporate structure reorganization, including the relocation of our EMEA regional headquarters to Switzerland.

We reorganized our corporate structure and intercompany relationships in January 2020 in an effort to more closely align our international business activities and to achieve financial and operational efficiencies. The implementation
of  this  reorganization  plan  included  the  move  of  our  EMEA  regional  headquarters  from  the  Netherlands  to  Switzerland,  has  been  time-consuming  and  costly,  may  be  disruptive  to  our  business,  and,  following  completion  of  the
reorganization plan, may not be more efficient or effective. This relocation is accompanied by a number of risks and uncertainties that may affect our results of operations and statement of cash flows, including:

25

•
•
•

failure to retain key employees who possess specific knowledge or expertise and upon whom we are depending upon for the timely and successful transition; 
difficulties in hiring employees in Switzerland with the necessary skills and expertise; and
increased costs as we transition the operations to Switzerland along with higher costs of doing business in Switzerland.

If any of these risks materialize in the future, our operating results, statement of operations and cash flows may be adversely affected.

Our effective tax rate may vary significantly from period to period.

Various internal and external factors may have favorable or unfavorable effects on our future effective tax rate. These factors include, but are not limited to, changes in legal entity structure and/or activities performed within our
entities, changes in tax laws, regulations and/or rates, new or changes to accounting pronouncements, changing interpretations of existing tax laws or regulations, changes in the relative proportions of revenues and income before taxes in
the various jurisdictions in which we operate that have differing statutory tax rates, changes in overall levels of pretax earnings, the future levels of tax benefits of stock-based compensation, settlement of income tax audits and non-
deductible goodwill impairments. For example, our effective tax rate will vary significantly in our first quarter of fiscal 2020 due to the relocation of our EMEA regional headquarters from the Netherlands to Switzerland effective January
1, 2020. Also, we may continue to experience significant variation in our effective tax rate related to excess tax benefits on stock-based compensation, particularly in the first quarter of each year when the majority of our equity awards
vest.

Changes in tax laws or tax rulings could negatively impact our income tax provision and net income.

As a U.S. multinational corporation, we are subject to changing tax laws both within and outside of the U.S. Changes in tax laws or tax rulings, or changes in interpretations of existing tax laws, could affect our income tax provision
and net income or require us to change the manner in which we operate our business. In addition, governmental tax authorities are increasingly scrutinizing the tax positions of companies. Many countries in Europe, as well as a number of
other countries and organizations, have recently proposed or recommended changes to existing tax laws or have enacted new laws. For example, the Organization for Economic Cooperation and Development (“OECD”) has been working
on a “Base Erosion and Profit Shifting Project,” which is focused on a number of issues, including the shifting of profits between affiliated entities in different tax jurisdictions. The OECD has issued and is expected to continue to issue,
guidelines and proposals that may change various aspects of the existing framework under which our tax obligations are determined in many of the countries in which we do business.

We are subject to risks associated with our strategic investments. Impairments in the value of our investments and unsecured promissory note could negatively impact our financial results.

We have invested in privately held companies for strategic reasons and to support key business initiatives, and we may not realize a return on our strategic investments. Many of such companies generate net losses and the market for
their  products,  services  or  technologies  may  be  slow  to  develop.  Further,  valuations  of  privately  held  companies  are  inherently  complex  due  to  the  lack  of  readily  available  market  data.  If  we  determine  that  our  investments  have
experienced a decline in value or are determined to be uncollectible, we may be required to record impairments which could be material and could have an adverse impact on our financial results.

Risks Related to our Common Stock

Historically, the market price for our common stock has been volatile.

The market price of our common stock could be subject to wide price fluctuations in response to various factors, many of which are beyond our control. The factors include:

•
•
•
•
•
•
•
•
•
•

quarterly variations in our results of operations and liquidity or changes in our forecasts and guidance;
changes in recommendations by the investment community or in their estimates of our net revenues or operating results;
speculation in the press or investment community concerning our business and results of operations;
announcements by competitors or new market entrants;
strategic actions by us or our competitors, such as management changes, material transactions or acquisitions;
announcements regarding stock repurchases, sales of our common stock, credit agreements and debt issuances;
announcements of technological innovations or new products or product offerings by us, our customers or competitors;
key decisions in pending litigation
sales of stock by us, our officers or directors; and
general economic market conditions.

26

In addition, the stock market, in general, and the market for technology and medical device companies, in particular, have experienced extreme price and volume fluctuations that have often been unrelated to or disproportionate to the
operating performance of those companies. These broad market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance. Historically, class action litigation is often brought
against an issuing company following periods of volatility in the market price of a company’s securities and we have not been excepted from such litigation.

We cannot guarantee we will continue to repurchase our common stock, and any repurchases may not achieve our objectives.

We have a history of recurring stock repurchase programs intended to return capital to our investors. Any authorization or continuance of our share repurchase programs is contingent on a variety of factors, including our financial
condition, results of operations, business requirements, and our board of directors' continuing determination that share repurchases are in the best interests of our stockholders and in compliance with all applicable laws and agreements.
There is no assurance that we will continue to repurchase stock consistent with historical levels or at all, or that our stock repurchase programs will have a beneficial impact on our stock price.

Future sales of significant amounts of our common stock may depress our stock price.

A  large  percentage  of  our  outstanding  common  stock  is  currently  owned  by  a  small  number  of  significant  stockholders. These  stockholders  have  sold  in  the  past,  and  may  sell  in  the  future,  large  amounts  of  common  stock  over
relatively short periods of time. Sales of substantial amounts of our common stock in the public market by our existing stockholders may adversely affect the market price of our common stock. Such sales could create public perception of
difficulties or problems with our business and may depress our stock price.

Market Information

As of February 21, 2020, there were approximately 70 holders of record of our common stock. Because the majority of our shares of outstanding common stock are held by brokers and other institutions on behalf of stockholders, we

are unable to estimate the total number of stockholders represented by these record holders.

Performance Graph

Notwithstanding any statement to the contrary in any of our previous or future filings with the SEC, the following information relating to the price performance of our common stock shall not be deemed “filed” with the SEC or
“Soliciting Material” under the Securities Exchange Act of 1934, as amended, or subject to Regulation 14A or 14C, or to liabilities of Section 18 of the Exchange Act except to the extent we specifically request that such information be
treated as soliciting material or to the extent we specifically incorporate this information by reference.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read together with “Selected Consolidated Financial Data” and our consolidated financial statements and related notes included

elsewhere in this Annual Report on Form 10-K.

A discussion regarding our financial condition and results of operations for fiscal 2019 compared to fiscal 2018 is presented under Results of Operations of this Form 10-K. Discussions regarding our financial condition and results of
operations for fiscal 2018 compared to 2017 have been omitted from this Annual Report on Form 10-K, but can be found in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual
Report  on  Form  10-K  for  the  fiscal  year  ended  December  31,  2018,  filed  with  the  SEC  on  February  28,  2019,  which  is  available  without  charge  on  the  SEC's  website  at  www.sec.gov  and  on  our  investor  relations  website  at
investor.aligntech.com.

Overview

Our goals are to establish Invisalign clear aligners as the standard method for treating malocclusion which, to date, over 8 million people worldwide have been treated with our Invisalign System, and to establish the iTero intraoral
scanner as the preferred scanning device for 3D digital scans, ultimately driving increased clear aligner and other product adoption by dental professionals. We intend to achieve these goals by continued focus and execution of our strategic
growth drivers set forth in the Business Strategy section of this Annual Report on Form 10-K.

The successful execution of our business strategy in 2020 and beyond may be affected by a number of factors including:

• New Invisalign Products and Feature Enhancements. We believe product innovation drives greater treatment predictability, clinical applicability and ease of use for the dental professionals we serve customers which supports

adoption of Invisalign treatment in their practices. Our focus is to develop solutions and features to treat a wide range of cases from simple to complex.

• We rolled out Invisalign treatment with Mandibular Advancement, the first clear aligner solution for Class II correction in growing tween and teen patients in multiple regions and countries throughout 2018. This offering

combines the benefits of our clear aligner system with features for moving the lower jaw forward while simultaneously aligning the teeth without the need for elastics typically used to treat teen Class II patients.

•

•

•

In April 2018, we announced Invisalign Go product with more user-friendly iTero digital chairside experience and greater flexibility to treat a wider range of mild to moderate cases. Invisalign Go also incorporates new data-
driven clinical protocols for predictable tooth movement and automated case assessments that leverages our Invisalign patients treated to date. These improvements make it easier for general practitioner (“GP”) dentists to
tailor their treatment plans to the individual needs of each patient.

In July 2018, we announced Invisalign First clear aligners which are a treatment option designed with features specifically for younger patients with early mixed dentition with a mixture of primary/baby and permanent teeth.
Phase 1 treatment is an early interceptive orthodontic treatment for young patients, traditionally done through arch expanders, or partial metal braces, before all permanent teeth have erupted, typically at ages seven through ten
years. Invisalign First clear aligners are designed specifically to address a broad range of younger patients’ malocclusions, including shorter clinical crowns, management of erupting dentition and predictable dental arch
expansion.

In October 2019, we launched the Invisalign Moderate Package for the treatment of mild to moderate malocclusion. The Invisalign Moderate treatment includes all the features of Invisalign treatment, plus additional features
that address the orthodontic needs of teenage patients such as compliance indicators and compensation for tooth eruption. 

• New iTero Products and Technology Innovation. The iTero scanner is an important component to our customer experience and is central to a digital approach as well as overall customer utilization of Invisalign.

•

In April 2018, we expanded the iTero Element portfolio with the launch of the iTero Element 2 and the iTero Element Flex scanners, building on the existing high precision, full-color imaging and fast scan times of the iTero
Element portfolio while streamlining orthodontic and restorative workflows. The next-generation iTero Element 2 is designed for greater performance with 2X faster start-up and 25% faster scan processing time compared to
the iTero Element. The new iTero Element Flex wand-only configuration is a portable scanner for easy transport from office to office.

30

As we continue to expand our global presence, we expect to seek regulatory approvals to offer our iTero portfolio products in more countries, thereby tapping potential growth opportunities in underserved markets

•

•

In February 2019, we announced the launch of iTero Element 5D Imaging System for comprehensive, preventative and restorative oral care. The iTero Element 5D Imaging System provides a new comprehensive approach to
clinical applications, workflows and user experience that expands the suite of existing high-precision, full color imaging and fast scan times of the iTero Element portfolio. The iTero Element 5D Imaging System is available in
the majority of EMEA and select APAC countries. The iTero Element 5D Imaging System is pending regulatory approval and is not yet available in the U.S. or LATAM countries.

In June 2019, we announced the launch of iTero Element Foundation intraoral scanner with restorative software. The iTero Element Foundation extends Align’s portfolio of intraoral scanners with powerful 3D visualization to
better meet the needs of doctors, labs and patients. The iTero Element Foundation is available in North America and will also be available in other select countries in 2020.

We believe that over the longterm, clinical solutions and treatment tools will increase adoption of Invisalign and increase sales of our intraoral scanners; however, it is difficult to predict the rate of adoption which may vary by
region and channel.

The use of iTero and other digital scanners for Invisalign case submission in place of PVS impressions continues to grow and remains a positive catalyst for Invisalign utilization. For the fourth quarter of 2019, total Invisalign
cases submitted with a digital scanner in the Americas increased to 79.5%, up slightly from 78.8% in the third quarter of 2019. International scans increased to 64.7%, up from 62.6% in the third quarter of 2019. We believe that
over the longterm, technology innovation and added features and functionality of our iTero scanners will increase adoption of Invisalign and increase sales of our intraoral scanners; however, it is difficult to predict the rate of
adoption which may vary by region and channel.

•

Invisalign Adoption. Our goal is to establish Invisalign as the treatment of choice for treating malocclusion ultimately driving increased product adoption and frequency of use by dental professionals, also known as “utilization
rates.” Our annual utilization rates for the last three fiscal years are as follows:

* Invisalign utilization rates are calculated by the # of cases shipped divided by the # of doctors to whom cases were shipped. Our International region includes EMEA and APAC. LATAM is excluded from the above chart as it is immaterial.

◦

Total utilization in 2019 increased to 15.9 cases per doctor compared to 15.7 cases in 2018.

▪

North America: Utilization for both our North American orthodontist and GP customers increased in 2019 to 65.0 and 9.5 cases per doctor compared to 56.7 cases and 9.1 cases per doctor in 2018, respectively. The
increase in utilization in 2019 reflects improvements in product and technology which continues to strengthen

31

our doctors’ clinical confidence such that they now utilize Invisalign more often and on more complex cases, including their teenage patients.

▪

International: International doctor utilization remained relatively flat at 13.8 cases per doctor in 2019 compared to 13.9 cases in 2018.

We expect our utilization rates to gradually improve as a result of advancements in product and technology, which continue to strengthen our doctors’ clinical confidence in the use of Invisalign clear aligners. In addition, since the
teenage and younger market makes up 75% of the approximately 12 million total orthodontic case starts each year, and as we continue to drive adoption of teenage and younger patients through sales and marketing programs, we
expect our utilization rates to improve. Our utilization rates, however, may fluctuate from period to period due to a variety of factors, including seasonal trends in our business along with adoption rates of new products and
features.

• Number of New Invisalign Doctors Trained. We continue to expand our Invisalign customer base through the training of new doctors. In 2019, we trained 22,270 new Invisalign doctors of which 9,765 were trained in the Americas

region and 12,505 in the International region.

•

•

International  Invisalign  Growth.  We  continue  to  focus  our  efforts  towards  increasing  Invisalign  clear  aligner  adoption  by  dental  professionals  in  the  EMEA  and  APAC  markets.  On  a  year-over-year  basis,  our  International
Invisalign volume increased 34.0% driven primarily by increased adoption as well as expansion of our customer base in both the EMEA and APAC regions. However, beginning in the second quarter of 2019, we experienced
slower  growth  rates  than  prior  periods  in  China  primarily  due  to  the  US-China  trade  war  and  resulting  economic  uncertainty  which  caused  headwind  for  consumer  demand  especially  for  consumption  of  luxury  goods  and
considered purchases. We also believe there has been increased competitive activity from wires and bracket manufacturers and clear aligner suppliers. In addition, in the first quarter of 2020, the outbreak of the Novel Coronavirus
(2019  NCov)  in  China  has  caused  increased  uncertainty  and  disruption  to  our  employees,  doctors’  practices,  their  patients  and  consumers.  We  expect  the  impact  of  the  Novel  Coronavirus  and  related  efforts  by  the  Chinese
government to contain its spread, including travel restrictions, extension of the Lunar New Year and discouraging non-essential medical and dental procedures to adversely impact sales and operations in China for a currently
indeterminate period of time. Notwithstanding these current issues in China, we continue to see growth from our international orthodontists and GP customers and are seeing more positive traction in the GP channel as we continue
to segment our sales and marketing resources and programs specifically around each customer channel. In 2019, we continued to expand in our existing markets through targeted investments in sales coverage and professional
marketing and education programs, along with consumer marketing in select country markets. We expect International revenues to continue to grow at a faster rate than the Americas for the foreseeable future due to our continued
investment in international market expansion, the size of the market opportunities and our relatively low market penetration of these regions. Our future growth is dependent upon the continued growth of Invisalign adoption and
international market penetration.

Increasing Competition. Starting in the second quarter of 2019, we began experiencing slower adult case growth from North American orthodontists, reflecting a more competitive environment especially for the young adult
demographic. Given increased awareness for direct to consumer clear aligners and heavy advertising spend from direct to consumer companies, case starts may be shifting away from traditional practices. We also believe that
doctors are sampling alternative products and/or taking advantage of wires and brackets bundles that essentially give clear aligners away for free or at low prices. In the third quarter of 2019, we increased investment in consumer
demand with a new advertising campaign for North America and expanding marketing programs such as our Concierge Service, which connects potential patients with Invisalign doctors increasing conversion and loyalty. In
addition, we launched new sales tools and professional marketing materials and we also expect to see increased productivity from the approximate 100 sales representatives we added in the first quarter of 2019. If, however, we are
unable to compete effectively with existing products or respond effectively to any products developed by new or existing competitors, our business could be harmed.

• Establish Regional Order Acquisition, Treatment Planning and Manufacturing Operations. We expect to continue establishing and expanding additional order acquisition, treatment planning and manufacturing operations closer to
our international customers in order to improve our operational efficiency and increase doctors' confidence in Invisalign clear aligners. In the fourth quarter of 2018, we began fabricating our aligners in our manufacturing facility
in Ziyang, China, our first aligner fabrication facility outside of Juarez, Mexico. In the third quarter of 2019, we opened our new order acquisition and treatment facility in Wroclaw, Poland and new treatment facility in Yokohama,
Japan.

• Corporate Structure Reorganization. In January 2020, we reorganized our corporate structure and intercompany relationships to more closely align with the international nature of our business activities with the goal of achieving

financial and operational efficiencies. As part of this corporate structure reorganization, our EMEA regional headquarters

32

was moved from Amsterdam, the Netherlands to Rotkreuz, Switzerland. As a result, we will continue to incur expenses in the near term and expect to realize the related benefits in subsequent years. The implementation of this
reorganization plan has been disruptive to our business, and may not ultimately be more efficient or effective. Moreover, our reorganization activities, including any related expenses and the impact from affected employees, could
have a material adverse effect on our business, operating results, financial condition and effective tax rates.

• Expenses. We expect expenses to increase in 2020 due in part to:

▪
▪
▪
▪
▪

Investments in manufacturing capacity and facilities to enhance our regional capabilities;
Investments in international expansion;
Investments in expansion of number of direct sales force personnel;
Increase in sales, marketing and customer support resources including our new advertising campaign; and
Product and technology innovation to enhance product efficiency and operational productivity.

We believe that these investments will position us to increase our revenues and continue to grow our market share, but will negatively impact results of operations, particularly in the near term.

•

Stock  Repurchases.  During  the  year  ended  December  31,  2019,  we  repurchased  $200.0  million  of  our  common  stock  on  the  open  market  at  an  average  price  of  $264.93  per  share.  We  also  entered  into  an  accelerated  stock
repurchase agreement to repurchase $200.0 million of our common stock and received a total of 1.1 million shares for an average share price of $176.61. As of December 31, 2019, we have $100.0 million available for repurchase
under the $600.0 million repurchase program authorized by our Board of Directors in May 2018 (Refer to Note 12 “Common Stock Repurchase Programs” of the Notes to Consolidated Financial Statements for details on our
stock repurchase programs).

Total net revenues increased by $440.3 million in 2019 as compared to 2018 primarily as a result of Invisalign case and scanner volume growth across all regions.

Clear Aligner - Americas

Americas net revenues increased by $118.8 million in 2019 as compared to 2018 due to Invisalign case volume growth across all channels and products which contributed to the net revenue growth by $100.2 million and higher
average selling prices ("ASP") which increased net revenues by $18.7 million. Higher ASP was mainly the result of price increases across most products which increased net revenues by $35.1 million and $23.4 million increase in net
revenues driven by a product mix shift towards Comprehensive products and less SDC revenues, which carry a lower ASP. We no longer manufacture aligners for SDC as our supply agreement with SDC expired by its terms on December
31, 2019. These ASP increases were partially offset by a reduction in net revenues of $23.1 million from higher promotional discounts and $17.6 million reduction in net revenues as a result of higher net revenue deferrals and unfavorable
foreign exchange rates.

Clear Aligner - International

International net revenues increased by $197.2 million in 2019 as compared to 2018 primarily  driven  by  case  volume  growth  across  all  channels  and  products  which  increased  net  revenues  by  $232.5  million.  This  increase  was
partially offset by lower ASP that reduced net revenues by $35.3 million. The ASP decline was mainly the result of higher promotional discounts which reduced net revenues by $45.0 million, unfavorable foreign exchange rates lowered
net revenues by $37.2 million, and a product mix shift towards Non-comprehensive products reduced net revenues by $19.0 million. These ASP decreases were partially offset by a $47.8 million improvement in net revenues related to
price increases across most products along with a benefit from going direct in several additional countries, and lower net revenue deferrals and sales credits that increased net revenues by $18.1 million.

Clear Aligner - Non-Case

Non-case net revenues, consisting of Vivera Retainers, training fees and other product revenues, increased by $18.3 million in 2019 compared to 2018 due to increased Vivera volume across all regions.

Scanner

Scanner and services net revenues increased by $106.0 million in 2019 as compared to 2018.  This  increase  is  primarily  a  result  of  scanner  volume  growth  which  increased  net  revenues  by  $58.4  million,  and  higher  CAD/CAM
services that increased net revenues by $37.7 million primarily due to a larger install base and increased scanner subscription services. Additionally, net revenues increased by $10.0 million due to an improvement in the scanner ASP
mainly attributable to price increases in several regions.

Clear Aligner

Operating margin percentage decreased in 2019 compared to 2018 primarily due to lower Clear Aligner gross margin percentage as a result of an increase in aligners per case combined with impairment charges on operating lease

right-of-use assets, store leasehold improvement and other fixed assets. These decreases were partially offset by a gain recognized from the litigation settlement with Straumann.

Scanner

Operating margin percentage remained flat in 2019 compared to 2018 primarily due to manufacturing efficiencies and higher ASP partially offset by higher operating expenses.

The increase in effective tax rate for the year ended December 31, 2019 compared to the same period in 2018 is primarily attributable to tax benefits recorded last year as a result of expiration of statute limitations that did not recur in
2019 and reduced excess tax benefits from stock-based compensation mainly due to non-deductible officers’ compensation. For the year ended December 31, 2019 and December 31, 2018, we recognized tax benefits in our provision for
income taxes of $1.6 million and $22.5 million, respectively, related to expiration of statute of limitations and $13.4 million and $26.5 million, respectively, related to stock-based compensation.

Effective January 1, 2020, as a result of the relocation of our EMEA regional headquarters from Amsterdam, the Netherlands to Rotkreuz, Switzerland, our tax rate for the first quarter of 2020 and for the rest of the year, will reflect a
significant one-time tax benefit of up to $1.6 billion associated with the recognition of a deferred tax asset related to the intra-entity transfer of certain intellectual property rights. We continue to assess the realizability of this deferred tax
asset as we take into account new information, including the profitability of our Swiss headquarters and ongoing communication with the Swiss tax authorities.

Liquidity and Capital Resources

We fund our operations from product sales. As of December 31, 2019 and 2018, we had the following cash and cash equivalents, and short-term and long-term marketable securities (in thousands):

primarily include commercial paper, corporate bonds, U.S. government agency bonds, U.S. government treasury bonds, and certificates of deposit.

As of December 31, 2019, approximately $278.5 million of cash, cash equivalents and marketable securities was held by our foreign subsidiaries. We repatriated $350.0 million to the U.S. during the year ended December 31, 2019
under the Global Intangible Low-Taxed Income (“GILTI”) provisions of the U.S. Tax Cuts and Jobs Act (the “TCJA”) and substantially all of the earnings previously determined to be not indefinitely reinvested have been repatriated. Our
intent is to permanently reinvest our earnings from our international operations going forward, and our current plans do not require us to repatriate them to fund our U.S. operations as we generate sufficient domestic operating cash flow
and have access to external funding under our current revolving line of credit.

•

Stock-based compensation of $88.2 million related to equity awards granted to employees and directors;
Depreciation and amortization of $79.0 million related to our investments in property, plant and equipment and intangible assets;

Non-cash operating lease costs of $18.5 million; and
Gain from the sale of equity method investment of $15.8 million.

Significant changes in working capital

• Increase of $189.1 million in deferred revenues corresponding to the increase in case volume;
• Increase of $121.0 million in accounts receivable which is primarily a result of the increase in net revenues; and
• Increase of $60.2 million in accrued and other long-term liabilities due to timing of payment and activities.

For the year ended December 31, 2018, cash flows from operations of $554.7 million resulted primarily from our net income of approximately $400.2 million as well as the following:

Significant non-cash activities

•
•
•

Stock-based compensation of $70.8 million related to equity awards granted to employees and directors;

Increase of $109.2 million in accounts receivable which is primarily a result of the increase in net revenues; and
Decrease of $36.5 million in long-term income tax payable due to timing of payments made to IRS.

Investing Activities

Net cash used in investing activities was $350.4 million for the year ended December 31, 2019, which primarily consisted of purchases of marketable securities of $693.3 million, purchases of property, plant and equipment of $149.7
million and other investing activities of $14.7 million. These outflows were partially offset by maturities and sales of marketable securities of $485.4 million and payments of $21.8 million received on an unsecured promissory note issued
by SDC in exchange for tendering our shares to them.

For 2020, we expect to invest $180 million to $200 million in capital expenditures related to building purchases and improvements as well as additional manufacturing capacity to support our international expansion. Although we

believe our current investment portfolio has little risk of impairment, we cannot predict future market conditions or market liquidity and can provide

39

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
no assurance that our investment portfolio will remain unimpaired (Refer to Note 10 “Commitments and Contingencies” of the Notes to Consolidated Financial Statements for details on the purchases of buildings in Petach Tivka, Israel
and San Jose, California).

Net cash provided by investing activities was $6.9 million for the year ended December 31, 2018, which primarily consisted of maturities and sales of our marketable securities of $384.7 million and loan repayment from equity
investee of $30.0 million. These inflows were partially offset by purchases property, plant and equipment of $223.3 million, purchases of marketable securities of $180.2 million and purchases of investments in privately held companies of
$5.0 million.

Financing Activities

Net cash used in financing activities was $485.5 million for the year ended December 31, 2019 primarily consisted of common stock repurchases of $400.0 million, payroll taxes paid for equity awards through share withholdings of

$57.7 million and the purchase of a building that we previously leased under a finance lease of $45.8 million. These outflows were offset in part by $17.9 million proceeds from the issuance of common stock.

Net cash used in financing activities was $369.4 million for the year ended December 31, 2018 primarily consisted of common stock repurchases of $300.0 million and payroll taxes of $86.1 million paid for vesting of RSUs through

share withholdings. These outflows were offset in part by $16.6 million from proceeds from the issuance of common stock.

Common Stock Repurchases

Refer to Note 12 "Common Stock Repurchase Programs" of the Notes to Consolidated Financial Statements for details.

•

April 2016 Repurchase Program. In 2018, we repurchased approximately $200.0 million of our common stock on the open market, completing the April 2016 Repurchase Program.

• May 2018 Repurchase Program. In May 2018, we announced that our Board of Directors had authorized a plan to repurchase up to $600.0 million of our common stock. We repurchased $100.0 million and $400.0 million of our

common stock in 2018 and 2019, respectively, and as of December 31, 2019, we have $100.0 million remaining under this program.

We  believe  that  our  current  cash,  cash  equivalents  and  marketable  securities  combined  with  our  existing  borrowing  capacity  will  be  sufficient  to  fund  our  operations  for  at  least  the  next  12  months.  If  we  are  unable  to  generate
adequate operating cash flows and need more funds beyond our available liquid investments and those available under our credit facility, we may need to suspend our stock repurchase programs or seek additional sources of capital through
equity or debt financing, collaborative or other arrangements with other companies, bank financing and other sources in order to realize our objectives and to continue our operations. There can be no assurance that we will be able to obtain
additional debt or equity financing on terms acceptable to us, or at all. If adequate funds are not available, we may need to make business decisions that could adversely affect our operating results such as modifications to our pricing
policy, business structure or operations. Accordingly, the failure to obtain sufficient funds on acceptable terms when needed could have a material adverse effect on our business, results of operations and financial condition.

Credit Facility

On  February  27,  2018,  we  entered  into  a  new  credit  facility  for  a  $200.0  million  revolving  line  of  credit,  with  a  $50.0  million  letter  of  credit  sublimit,  and  a  maturity  date  of  February  27,  2021.  As  of  December  31,  2019,  we

had no outstanding borrowings under this credit facility (Refer to Note 7 "Credit Facility" of the Notes to Consolidated Financial Statements for details of the credit facility).

Our contractual obligations table above excludes approximately $42.7 million of non-current uncertain tax benefits which are included in other long-term obligations and deferred tax assets on our balance sheet as of December 31,

2019. We have not included this amount because we cannot make a reasonably reliable estimate regarding the timing of settlements with taxing authorities, if any.

As of December 31, 2019, we had additional operating leases that have not yet commenced of $7.9 million. These operating leases will commence between 2020 through 2021 with lease terms of 2 years to 4 years.

We had no material off-balance sheet arrangements as defined in Regulation S-K Item 303(a) (4) as of December 31, 2019 other than certain items disclosed in Note 10 "Commitments and Contingencies" of the Notes to Consolidated

Financial Statements.

Indemnification Provisions

In the normal course of business to facilitate transactions in our services and products, we indemnify certain parties: customers, vendors, lessors, and other parties with respect to certain matters, including, but not limited to, services
to be provided by us and intellectual property infringement claims made by third parties. In addition, we have entered into indemnification agreements with our directors and our executive officers that will require us, among other things, to
indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. Several of these agreements limit the time within which an indemnification claim can be made and the amount of the claim.

It is not possible to make a reasonable estimate of the maximum potential amount under these indemnification agreements due to the unique facts and circumstances involved in each particular agreement. Additionally, we have a
limited history of prior indemnification claims and the payments we have made under such agreements have not had a material adverse effect on our results of operations, cash flows or financial position. However, to the extent that valid
indemnification claims arise in the future, future payments by us could be significant and could have a material adverse effect on our results of operations or cash flows in a particular period. As of December 31, 2019, we did not have any
material indemnification claims that were probable or reasonably possible.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in
the United States of America. The preparation of financial statements requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, revenues and expenses and disclosures at the date of the
financial  statements.  We  evaluate  our  estimates  on  an  on-going  basis,  including  those  related  to  revenue  recognition,  stock-based  compensation,  goodwill  and  finite-lived  assets  and  related  impairment,  and  income  taxes.  We  use
authoritative pronouncements, historical experience and other assumptions as the basis for making estimates. Actual results could differ from those estimates.

We believe the following critical accounting policies and estimates affect our more significant judgments used in the preparation of our consolidated financial statements. For further information on all of our significant accounting

policies, see Note 1 "Summary of Significant Accounting Policies" of the Notes to Consolidated Financial Statements under Item 8.

Revenue Recognition

Our revenues are derived primarily from the sale of aligners, scanners, and services from our Clear Aligner and Scanner segments. We enter into sales contracts that may consist of multiple distinct performance obligations where

certain performance obligations of the sales contract are not delivered in one reporting period. We measure and allocate revenues according to ASC 606-10, “Revenues from Contracts with Customers.”

We identify a performance obligation as distinct if both of the following criteria are met: the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer
and the entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract. Determining the standalone selling price (“SSP”), allocation of consideration from the contract to the
individual performance obligations and the appropriate timing of revenue recognition, is the result of significant qualitative and quantitative judgments. While changes in the allocation of the SSP between performance obligations will not
affect the amount of total revenues recognized for a particular contract, any material changes could impact the timing of revenue recognition, which would have a material effect on our financial position and result of operations. This is
because the contract consideration is allocated to each performance obligation, delivered or undelivered, at the inception of the contract based on the SSP of each distinct performance obligation.

41

Clear Aligner

We enter into contracts (“treatment plan(s)”) that involve multiple future performance obligations. Invisalign Comprehensive, Invisalign First, Invisalign Moderate, and Lite and Express Packages, include optional additional aligners

at no charge for a certain period of time ranging from six months to five years after initial shipment, and Invisalign Go includes optional additional aligners at no charge for a period of up to two years after initial shipment.

Our treatment plans comprise the following performance obligations that also represent distinct deliverables: initial aligners, additional aligners, case refinement, and replacement aligners. We take the practical expedient to consider
shipping and handling costs as activities to fulfill the performance obligation. We allocate revenues for each treatment plan based on each unit’s SSP. Management considers a variety of factors such as historical sales, costs, and gross
margin, which may vary over time depending upon the unique facts and circumstances related to each performance obligation in making these estimates. We also consider usage rates, which is the number of times a customer is expected to
order additional aligners. Our process for estimating usage rates requires significant judgment and evaluation of inputs, including historical usage data by region, country and channel. We recognize the revenues upon shipment, as the
customers obtain physical possession and we have enforceable rights to payment. As we collect most consideration upfront, we consider whether a significant financing component exists; however, as the delivery of the performance
obligations are at the customer’s discretion, we conclude that no significant financing component exists.

Scanner

We sell intraoral scanners and CAD/CAM services through both our direct sales force and distribution partners. The intraoral scanner sales price includes one year of warranty and unlimited scanning services. The customer may also
select,  for  additional  fees,  extended  warranty  and  unlimited  scanning  services  for  periods  beyond  the  initial  year.  When  intraoral  scanners  are  sold  with  an  unlimited  scanning  service  agreement  and/or  extended  warranty,  we  allocate
revenues based on the respective SSPs of the scanner and the subscription service. We estimate the SSP of each element, taking into consideration historical prices as well as our discounting strategies. Revenues are then recognized over
time as the monthly services are rendered and upon shipment of the scanner, as that is when we deem the customer to have obtained control. Most consideration is collected upfront and in cases where there are payment plans, consideration
is collected by the one year mark and, therefore, there are no significant financing components.

Volume Discounts

In certain situations, we offer promotions in which the discount will increase depending upon the volume purchased over time. We concluded that in these situations, the promotions can represent either variable consideration or
options, depending upon the specifics of the promotion. In the event the promotion contains an option, the option is considered a material right and, therefore, included in the accounting for the initial arrangement. We estimate the average
anticipated discount over the lifetime of the promotion or contract, and apply that discount to each unit as it is sold. On a quarterly basis, we review our estimates and, if needed, updates are made and changes are applied prospectively.

Unfulfilled Performance Obligations for Clear Aligners and Scanners

Our unfilled performance obligations, including deferred revenues and backlog, as of December 31, 2019 and the estimated revenues expected to be recognized in the future related to these performance obligations are $610.3 million.
This includes performance obligations from the Clear Aligner segment, primarily the shipment of additional aligners, which are fulfilled over six months to five years. Also included are the performance obligations from the iTero scanner
segment, primarily services and support, which are fulfilled over one to five years, and contracted deliveries of additional scanners. The estimate includes both product and service unfulfilled performance obligations and the time range
reflects our best estimate of when we will transfer control to the customer and may change based on customer usage patterns, timing of shipments, readiness of customers' facilities for installation, and manufacturing availability.

Contract Balances

The timing of revenue recognition results in deferred revenues being recognized on our Consolidated Balance Sheet. For both aligners and scanners, we usually collect the total consideration owed prior to all performance obligations
being performed with payment terms generally varying from net 30 to net 180 days. Contract liabilities are recorded as deferred revenue balances, which are generated based upon timing of invoices and recognition patterns, not payments.
If the revenue recognition exceeds the billing, the exceeded amount is considered unbilled receivable and a contract asset. Conversely, if the billing occurs prior to the revenue recognition, the amount is considered deferred revenue and a
contract liability.

42

Goodwill and Finite-Lived Acquired Intangible Assets and Long-Lived Assets

Goodwill

Goodwill represents the excess of the purchase price paid over the fair value of tangible and identifiable intangible net assets acquired in business combinations and is allocated to the respective reporting units based on relative

synergies generated.

We evaluate goodwill for impairment at least annually on November 30th or more frequently if indicators are present, an event occurs or changes in circumstances suggest an impairment may exist and that it would more likely than

not reduce the fair value of a reporting unit below its carrying amount. The allocation of goodwill to the respective reporting unit is based on relative synergies generated as a result of an acquisition.  

We perform an initial assessment of qualitative factors to determine whether the existence of events and circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its
carrying amount. In performing the qualitative assessment, we identify and consider the significance of relevant key factors, events, and circumstances that affect the fair value of our reporting units. These factors include external factors
such as macroeconomic, industry, and market conditions, as well as entity-specific factors, such as our actual and planned financial performance. We  also  give  consideration  to  the  difference  between  the  reporting  unit  fair  value  and
carrying value as of the most recent date a fair value measurement was performed. If, after assessing the totality of relevant events and circumstances, we determine that it is more likely than not that the fair value of the reporting unit
exceeds its carrying value and there is no indication of impairment, no further testing is performed; however, if we conclude otherwise, the first step of the two-step impairment test is performed by estimating the fair value of the reporting
unit and comparing it with its carrying value, including goodwill. Refer to Note 6 "Goodwill and Intangible Assets" of Notes to Consolidated Financial Statements for details on goodwill.

Finite-Lived Intangible Assets and Long-Lived Assets

Our intangible assets primarily consist of intangible assets acquired as part of acquisitions and are amortized using the straight-line method over their estimated useful lives, reflecting the period in which the economic benefits of the

assets are expected to be realized.

We evaluate long-lived assets (including finite-lived intangible assets) for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. An asset or asset group
is considered impaired if its carrying amount exceeds the future undiscounted net cash flows the asset or asset group is expected to generate. If an asset or asset group is considered to be impaired, the impairment to be recognized is
calculated as the amount by which the carrying amount of the asset or asset group exceeds its fair market value. Our estimates of future cash flows attributable to our long-lived assets require significant judgment based on our historical and
anticipated  results  and  are  subject  to  many  factors.  Factors  we  consider  important  which  could  trigger  an  impairment  review  include  significant  negative  industry  or  economic  trends,  significant  loss  of  customers  and  changes  in  the
competitive environment. The estimation of fair value utilizing a discounted cash flow approach includes numerous uncertainties which require our significant judgment when making assumptions of expected growth rates and the selection
of discount rates, as well as assumptions regarding general economic and business conditions, and the structure that would yield the highest economic value, among other factors. Refer to Note 6 "Goodwill and Intangible Assets" of Notes
to Consolidated Financial Statements for details of the impairment analysis.

Accounting for Income Taxes

We make certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of certain tax assets and liabilities, which arise from differences in

the timing of recognition of revenue and expense for tax and financial statement purposes.

As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves us estimating our current tax exposure
under  the  applicable  tax  laws  and  assessing  temporary  differences  resulting  from  differing  treatment  of  items  for  tax  and  accounting  purposes.  These  differences  result  in  deferred  tax  assets  and  liabilities  which  are  included  in  our
Consolidated Balance Sheet.

We account for uncertainty in income taxes pursuant to authoritative guidance based on a two-step approach to recognize and measure uncertain tax positions taken or expected to be taken in a tax return. The first step is to determine
if the weight of available evidence indicates that it is more likely than not that the tax position will be sustained on audit based on its technical merits, including resolution of any related appeals or litigation processes. The second step is to
measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. We adjust reserves for our uncertain tax positions due to changing facts and circumstances, such as the closing of a tax audit
or refinement of estimates due to new

43

information. To the extent that the final outcome of these matters is different than the amounts recorded, such differences will impact our tax provision in our Consolidated Statement of Operation in the period in which such determination
is made.

We assess the likelihood that we will be able to realize our deferred tax assets. Should there be a change in our ability to realize our deferred tax assets, our tax provision would increase in the period in which we determine that it is
more likely than not that we cannot realize our deferred tax assets. We consider all available evidence, both positive and negative, including historical levels of income, expectations and risks associated with estimates of future taxable
income and ongoing prudent and feasible tax planning strategies in assessing the need for a valuation allowance. If it is more likely than not that we will not realize our deferred tax assets, we will increase our provision for taxes by
recording a valuation allowance against the deferred tax assets that we estimate will not ultimately be realized.

The U.S. Tax Cuts and Jobs Act includes provisions for certain foreign-sourced earnings referred to as Global Intangible Low-Taxed Income (“GILTI”) which imposes a tax on foreign income in excess of a deemed return on tangible

assets of foreign corporations. We have made the election to record GILTI tax using the period cost method.

effects on results of operations and financial condition, which is incorporated herein.

ITEM 7A.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In the normal course of business, we are exposed to foreign currency exchange rate and interest rate risks that could impact our financial position and results of operations.

Interest Rate Risk

Changes in interest rates could impact our anticipated interest income on our cash equivalents and investments in marketable securities. Our investments are fixed-rate short-term and long-term securities. Fixed-rate securities may
have their fair market value adversely impacted due to a rise in interest rates, and, as a result, our future investment income may fall short of expectations due to changes in interest rates or we may suffer losses in principal if forced to sell
securities which have declined in market value due to changes in interest rates. As of December 31, 2019, we had approximately $318.2 million invested in available-for-sale marketable securities. An immediate 10% change in interest
rates would not have a material adverse impact on our future operating results and cash flows.

We do not enter into investments for trading or speculative purposes and have not used any derivative financial instruments to manage our interest rate risk exposure. Based on interest bearing liabilities we have as of December 31,

2019, we are not subject to risks from immediate interest rate increases.

Currency Rate Risk

As  a  result  of  our  international  business  activities,  our  financial  results  could  be  affected  by  factors  such  as  changes  in  foreign  currency  exchange  rates  or  economic  conditions  in  foreign  markets,  and  there  is  no  assurance  that
exchange rate fluctuations will not harm our business in the future. We generally sell our products in the local currency of the respective countries. This provides some natural hedging because most of the subsidiaries’ operating expenses
are generally denominated in their local currencies. Regardless of this natural hedging, our results of operations may be adversely impacted by exchange rate fluctuations.

We enter into foreign currency forward contracts to minimize the short-term impact of foreign currency exchange rate fluctuations on cash and certain trade and intercompany receivables and payables. These forward contracts are not
designated as hedging instruments and do not subject us to material balance sheet risk due to fluctuations in foreign currency exchange rates. The gains and losses on these forward contracts are intended to offset the gains and losses in the
underlying foreign currency denominated monetary assets and liabilities being economically hedged. These instruments are marked to market through earnings every period and generally are one month in original maturity. We do not enter
into foreign currency forward contracts for trading or speculative purposes. As our international operations grow, we will continue to reassess our approach to managing the risks relating to fluctuations in currency rates. It is difficult to
predict the impact forward contracts could have on our results of operations. The fair value of foreign exchange forward contracts outstanding as of December 31, 2019 was not material.

44

Although we will continue to monitor our exposure to currency fluctuations, and, where appropriate, may use forward contracts to minimize the effect of these fluctuations, the impact of an aggregate change of 10% in foreign

currency exchange rates relative to the U.S. dollar on our results of operations and financial position could be material.

REPORT OF MANAGEMENT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of Align is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934.  Our internal control
over financial reporting is designed by, or under supervision of, our CEO and CFO, and effected by the board of directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and
the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that:

•

•

•

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of Align;

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of Align are
being made only in accordance with authorizations of management and directors of Align; and

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of Align's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may

become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2019. In making this assessment, management used the criteria set forth in Internal Control-Integrated Framework (2013)

issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO").

Based on our assessment, management has concluded that, as of December 31, 2019, our internal control over financial reporting was effective based on criteria in Internal Control - Integrated Framework (2013) issued by the COSO.

The effectiveness of our internal control over financial reporting as of December 31, 2019 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included

herein.

Opinions on the Financial Statements and Internal Control over Financial Reporting

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Align  Technology,  Inc.  and  its  subsidiaries  (the  “Company”)  as  of  December  31,  2019  and  2018,  and  the  related  consolidated  statements  of  operations,
comprehensive income, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2019, including the related notes and financial statement schedule listed in the index appearing under item 15 (a)(2)
(collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated
Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 2019 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects,
effective internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Change in Accounting Principle

As discussed in Note 1 to the consolidated financial statements, the Company changed the manner in which it accounts for leases in 2019.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial
reporting, included in the accompanying Report of Management on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal
control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the
Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of

material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that
respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and
significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control
over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other
procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance
with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect
the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting
principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide

48

reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may

become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates
to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our
opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it
relates.

Revenue Recognition - Determination of Standalone Selling Price of Distinct Performance Obligations in Clear Aligner Contracts

As described in Notes 1 and 17 to the consolidated financial statements, the Company recognized net revenues of $2 billion from its Clear Aligner segment for the year ended December 31, 2019. The Company enters into contracts
(“treatment plans”) that involve multiple future performance obligations. Management identifies a performance obligation as distinct if both of the following criteria are met: the customer can benefit from the good or service either on its
own or together with other resources that are readily available to the customer and the entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract. Determining the standalone
selling  price,  allocation  of  consideration  from  the  contract  to  the  individual  performance  obligations  and  the  appropriate  timing  of  revenue  recognition  is  the  result  of  significant  qualitative  and  quantitative  judgments.  Management
considers a variety of factors such as historical sales, costs, and gross margin, which may vary over time depending upon the unique facts and circumstances related to each performance obligation in making these estimates. Management
also considers usage rates, which is the number of times a customer is expected to order additional aligners. Management’s process for estimating usage rates requires significant judgment and evaluation of inputs, including historical usage
data by region, country and channel.

The principal considerations for our determination that performing procedures related to revenue recognition and the determination of standalone selling price of distinct performance obligations in Clear Aligner contracts is a critical
audit  matter  are  there  was  significant  judgment  by  management  in  determining  the  standalone  selling  price,  which  includes  significant  assumptions  related  to  usage  rates  for  each  distinct  performance  obligation.  This  in  turn  led  to
significant judgment, subjectivity, and effort in applying audit procedures to evaluate the judgments made by management in determining the estimates of standalone selling price and usage rates for each distinct performance obligation.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of
controls relating to revenue recognition, including controls over the determination of standalone selling price for each distinct performance obligation in the Company’s Clear Aligner contracts. These procedures also included,  among
others,  (i)  testing  management’s  process  for  determining  the  estimate  of  standalone  selling  price,  which  included  testing  the  completeness  and  accuracy  of  inputs  used  and  evaluating  the  reasonableness  of  factors  considered  by
management, such as historical sales, usage rates, costs, and gross margin, and (ii) testing management’s process for estimating usage rates, which included evaluating the reasonableness of inputs evaluated by management, including
historical usage data by region, country and channel.

Business Description

ALIGN TECHNOLOGY, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Align Technology, Inc. (“We”, “Our”, or “Align”) was incorporated in April 1997 in Delaware. Align is a global medical device company engaged in the design, manufacture and marketing of Invisalign® clear aligners and iTero®
intraoral scanners and services for orthodontics and restorative and aesthetic dentistry. Align’s products are intended primarily for the treatment of malocclusion or the misalignment of teeth and are designed to help dental professionals
achieve  the  clinical  outcomes  that  they  expect.  We  are  headquartered  in  San  Jose,  California  with  offices  worldwide.  Our  Americas  regional  headquarters  is  located  in  Raleigh,  North  Carolina;  our  European,  Middle  East  and  Africa
("EMEA") regional headquarters is located in Rotkreuz, Switzerland, which moved from Amsterdam, the Netherlands in January 2020; and our Asia Pacific ("APAC") regional headquarters is located in Singapore. We have two operating
segments: (1) Clear Aligner, known as the Invisalign System, and (2) Scanners and Services ("Scanner"), known as the iTero intraoral scanner and OrthoCAD services.

Basis of Presentation and Preparation

The consolidated financial statements include the accounts of Align and our wholly-owned subsidiaries after elimination of intercompany transactions and balances.  

During fiscal year 2018, we adopted Accounting Standards Codification (“ASC”) 606, “Revenues from Contracts with Customers,” using the full retrospective method and ASU 2016-18, “Statement of Cash Flows - Restricted Cash,”
on a retrospective basis. The Consolidated Statement of Cash Flow for the year ended December 31, 2017 and Consolidated Statement of Stockholders' Equity for the year ended December 31, 2017 have been recast to comply with the
adoption of these standards.

Use of Estimates

The  preparation  of  financial  statements  in  conformity  with  generally  accepted  accounting  principles  ("GAAP")  in  the  United  States  ("U.S.")  requires  our  management  to  make  estimates  and  assumptions  that  affect  the  amounts
reported in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, useful
lives of intangible assets and property and equipment, long-lived assets and goodwill, income taxes and contingent liabilities, the fair values of financial instruments, stock-based compensation, unsecured promissory note receivable, and
valuation of investments in privately held companies among others. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making
judgments about the carrying values of assets and liabilities.

Fair Value of Financial Instruments

We measure the fair value of financial assets as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We use the GAAP fair
value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. This hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair
value. The three levels of inputs that may be used to measure fair value:

Level 1 - Quoted (unadjusted) prices in active markets for identical assets or liabilities.

Level 2 - Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or
other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. We obtain fair values for our Level 2 investments. Our custody bank and asset managers independently
use professional pricing services to gather pricing data which may include quoted market prices for identical or comparable financial instruments, or inputs other than quoted prices that are observable either directly or indirectly, and we are
ultimately responsible for these underlying estimates.

Level 3 - Unobservable inputs to the valuation methodology that are supported by little or no market activity and that are significant to the measurement of the fair value of the assets or liabilities. Level 3 assets and liabilities include

those whose fair value measurements are determined using pricing models, discounted cash flow methodologies or similar valuation techniques, as well as significant management judgment or estimation.

55

    
Cash and Cash Equivalents

We consider currency on hand, demand deposits, time deposits, and all highly liquid investments with an original or remaining maturity of three months or less at the date of purchase to be cash and cash equivalents. Cash and cash

equivalents are held in various financial institutions in the U.S. and internationally.

Restricted Cash

The restricted cash primarily consists of funds reserved for legal requirements. Restricted cash balances are primarily included in other assets within our Consolidated Balance Sheet.

Marketable Securities

Our marketable securities consist of marketable debt securities which are classified as available-for-sale and are carried at fair value. Marketable securities classified as current assets have maturities within one year. Unrealized gains
or losses on such securities are included in accumulated other comprehensive income (loss), net in stockholders’ equity. Realized gains and losses from maturities of all such securities are reported in earnings and computed using the
specific identification cost method. Realized gains or losses and charges for other-than-temporary declines in value, if any, on available-for-sale securities are reported in other income (expense), net, as incurred. We periodically evaluate
these investments for other-than-temporary impairment.

Variable Interest Entities

We  evaluate  whether  an  entity  in  which  we  have  made  an  investment  is  considered  a  variable  interest  entity  (“VIE”).  If  we  determine  we  are  the  primary  beneficiary  of  a  VIE,  we  would  consolidate  the  VIE  into  our  financial
statements. In determining if we are the primary beneficiary, we evaluate whether we have the power to direct the activities that most significantly impact the VIE's economic performance and the obligation to absorb losses or the right to
receive benefits of the VIE that could potentially be significant to the VIE. Our evaluation includes identification of significant activities and an assessment of our ability to direct those activities based on governance provisions and
arrangements  to  provide  or  receive  product  and  process  technology,  product  supply,  operations  services,  equity  funding,  financing,  and  other  applicable  agreements  and  circumstances.  Our  assessments  of  whether  we  are  the  primary
beneficiary  of  a  VIE  require  significant  assumptions  and  judgments.  We  have  concluded  that  we  are  not  the  primary  beneficiary  of  our  VIE  investments;  therefore,  we  do  not  consolidate  their  results  into  our  consolidated  financial
statements.

Investments in Privately Held Companies

Investments  in  privately  held  companies  in  which  we  can  exercise  significant  influence  but  do  not  own  a  majority  equity  interest  or  otherwise  control  are  accounted  for  under  ASC  323,  “Investments  -Equity  Method  and  Joint
Ventures.” Equity securities qualified as equity method investments are reported on our Consolidated Balance Sheet as a single amount, and we record our share of their operating results within equity in losses of investee, net of tax, in our
Consolidated  Statement  of  Operations.  Investments  in  privately  held  companies  in  which  we  cannot  exercise  significant  influence  and  do  not  own  a  majority  equity  interest  or  otherwise  control  are  accounted  for  under  ASC  321,
“Investments  -Equity  Securities.” The  equity  securities  without  readily  determinable  fair  values  are  recorded  at  cost  and  adjusted  for  impairments  and  observable  price  changes  with  a  same  or  similar  security  from  the  same  issuer
(“Measurement Alternative”). Equity securities under ASC 321 are reported on our Consolidated Balance Sheet as other assets, and we record a change in carrying value of our equity securities, if any, in other income (expense), net in our
Consolidated Statement of Operations.

Equity securities are evaluated for impairment as events or circumstances indicate that there is an other-than-temporary loss in value. The decrease in value is recognized in the period the impairment occurs and recorded in other

income (expense), net in the Consolidated Statement of Operations.

Derivative Financial Instruments

We enter into foreign currency forward contracts to minimize the short-term impact of foreign currency exchange rate fluctuations associated with certain assets and liabilities. These forward contracts are not designated as hedging
instruments and do not subject us to material balance sheet risk due to fluctuations in foreign currency exchange rates. The gains and losses on these forward contracts are intended to offset the gains and losses in the underlying foreign
currency denominated monetary assets and liabilities being economically hedged. We do not enter into foreign currency forward contracts for trading or speculative purposes. The net gain or loss from the settlement of these foreign
currency forward contracts is recorded in other income (expense), net in the Consolidated Statement of Operations.

56

Foreign Currency

For our international subsidiaries, we analyze on an annual basis or more often if necessary, if a significant change in facts and circumstances indicate that the functional currency has changed. For international subsidiaries where the
local currency is the functional currency, adjustments from translating financial statements from the local currency to the U.S. dollar reporting currency are recorded as a separate component of accumulated other comprehensive income
(loss), net in the stockholders’ equity section of the Consolidated Balance Sheet. This foreign currency translation adjustment reflects the translation of the balance sheet at period end exchange rates, and the income statement at an average
exchange rate in effect during the period. The foreign currency revaluation that are derived from monetary assets and liabilities stated in a currency other than functional currency are included in other income (expense), net. For the year
ended December 31, 2019, 2018 and 2017, we had foreign currency net gains (losses) of $(2.0) million, $(5.6) million and $9.0 million, respectively.

Certain Risks and Uncertainties

Our  operating  results  depend  to  a  significant  extent  on  our  ability  to  market  and  develop  our  products.  The  life  cycles  of  our  products  are  difficult  to  estimate  due,  in  part,  to  the  effect  of  future  product  enhancements  and

competition. Our inability to successfully develop and market our products as a result of competition or other factors would have a material adverse effect on our business, financial condition and results of operations.

Our cash and investments are held primarily by three financial institutions. Financial instruments which potentially expose us to concentrations of credit risk consist primarily of cash equivalents and marketable securities. We invest
excess cash primarily in money market funds, commercial paper, corporate bonds, U.S. government agency bonds, U.S. government treasury bonds and certificates of deposits. If the carrying value of our investments exceeds the fair value,
and the decline in fair value is deemed to be other-than-temporary, we will be required to write down the value of our investments, which could adversely affect our results of operations and financial condition. Moreover, the performance
of certain securities in our investment portfolio correlates with the credit condition of the U.S. economy. 

We provide credit to customers in the normal course of business. Collateral is not required for accounts receivable, but ongoing evaluations of customers’ credit worthiness are performed. We maintain reserves for potential credit
losses and such losses have been within management’s expectations. No individual customer accounted for 10% or more of our accounts receivable at December 31, 2019 or 2018, or net revenues for the year ended December 31, 2019,
2018 or 2017.

The U.S. Food and Drug Administration (“FDA”) and similar international agencies regulate the design, manufacture, distribution, pre-clinical and clinical study, clearance and approval of medical devices. Products developed by us
may require approvals or clearances from the FDA or other international regulatory agencies prior to commercialized sales. There can be no assurance that our products will receive any of the required approvals or clearances.  If we were
denied approval or clearance or such approval was delayed, it may have a material adverse impact on us.

We have manufacturing facilities located in Juarez, Mexico, where we conduct our aligner fabrication, distribution, repair of our iTero scanners and perform our CAD/CAM services. In the fourth quarter of 2018, we also began
fabricating our aligners in our manufacturing facility in Ziyang, China, our first aligner fabrication facility outside of Juarez, Mexico. In addition, we produce our handheld intraoral scanner wand, perform final scanner assembly and repair
our  scanners  at  our  facilities  in  Or  Yehuda,  Israel  and  Ziyang,  China.  Our  digital  treatment  plans  using  a  sophisticated,  internally  developed  computer-modeling  program  are  located  in  multiple  international  locations  to  support  our
customers within the regions. Our reliance on international operations exposes us to related risks and uncertainties, including difficulties in staffing and managing international operations such as hiring and retaining qualified personnel;
controlling production volume and quality of manufacture; political, social and economic instability; interruptions and limitations in telecommunication services; product and material transportation delays or disruption; trade restrictions
and changes in tariffs; import and export license requirements and restrictions; fluctuations in foreign currency exchange rates; and potential adverse tax consequences. If any of these risks materialize, our international manufacturing
operations, as well as our operating results, may be harmed.

We purchase certain inventory from sole suppliers. Additionally, we rely on a limited number of hardware manufacturers. The inability of any supplier or manufacturer to fulfill our supply requirements could materially and adversely

impact our future operating results.

Inventories

Inventories are valued at the lower of cost or net realizable value, with cost computed using standard cost which approximates actual cost on a first-in-first-out basis. Excess and obsolete inventories are determined primarily based on

future demand forecasts, and write-downs of excess and obsolete inventories are recorded as a component of cost of net revenues.

57

Property, Plant and Equipment

Property, plant and equipment are stated at historical cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets.
Construction in progress ("CIP") is related to the construction or development of property (including land) and equipment that have not yet been placed in service for their intended use. Upon sale or retirement, the asset’s cost and related
accumulated depreciation are removed from the balance sheet and any related gains or losses are reflected in income from operations. Maintenance and repairs are expensed as incurred. Refer to Note 3 "Balance Sheet Components" of the
Notes of Consolidated Financial Statements for details on estimated useful lives.

Leases

We lease office and retail spaces, vehicles and office equipment with original lease periods of up to 10 years. We determine if an arrangement is a lease at inception under ASC 842. Operating lease right-of-use (“ROU”) assets
represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at commencement date based on the
present value of lease payments over the lease term. If a lease arrangement does not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present
value of lease payments. We use the implicit rate when readily determinable. Our lease terms may include options to extend or terminate the lease which we include in our lease term when it is reasonably certain that we will exercise that
option. We have lease agreements with lease and non-lease components which are accounted for as a single lease component. Leases with an initial term of 12 months or less are not recorded on the balance sheet.

Goodwill and Finite-Lived Acquired Intangible Assets

Goodwill represents the excess of the purchase price paid over the fair value of tangible and identifiable intangible net assets acquired in business combinations and is allocated to the respective reporting units based on relative

synergies generated.

Our intangible assets primarily consist of intangible assets acquired as part of our acquisitions. These assets are amortized using the straight-line method over their estimated useful lives ranging from one to fifteen years, reflecting the

period in which the economic benefits of the assets are expected to be realized.

Impairment of Goodwill and Long-Lived Assets

Goodwill

We evaluate goodwill for impairment at least annually on November 30th or more frequently if indicators are present, an event occurs or changes in circumstances suggest an impairment may exist and that it would more likely than

not reduce the fair value of a reporting unit below its carrying amount. The allocation of goodwill to the respective reporting units is based on relative synergies generated as a result of an acquisition.  

We perform an initial assessment of qualitative factors to determine whether the existence of events and circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its
carrying amount. In performing the qualitative assessment, we identify and consider the significance of relevant key factors, events, and circumstances that affect the fair value of our reporting units. These factors include external factors
such as macroeconomic, industry, and market conditions, as well as entity-specific factors, such as our actual and planned financial performance. We also give consideration to the difference between the reporting unit fair value and
carrying value as of the most recent date a fair value measurement was performed. If, after assessing the totality of relevant events and circumstances, we determine that it is more likely than not that the fair value of the reporting unit
exceeds its carrying value and there is no indication of impairment, no further testing is performed; however, we conclude otherwise, the first step of the two-step impairment test is performed by estimating the fair value of the reporting
unit and comparing it with its carrying value, including goodwill.

Step one of the goodwill impairment test consists of a comparison of the fair value of a reporting unit against its carrying amount, including the goodwill allocated to each reporting unit. If the carrying amount of the reporting unit is
in excess of its fair value, step two requires the comparison of the implied fair value of the reporting unit’s goodwill against the carrying amount of the reporting unit’s goodwill. Any excess of the carrying value of the reporting unit’s
goodwill over the implied fair value of the reporting unit’s goodwill is recorded as an impairment loss in the Consolidated Statement of Operations.

Finite-Lived Intangible Assets and Long-Lived Assets

We evaluate long-lived assets (including finite-lived intangible assets) for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. An asset or asset group

is considered impaired if its carrying amount exceeds the future undiscounted net cash flows that the asset or asset group is expected to

58

generate. Factors we consider important which could trigger an impairment review include significant negative industry or economic trends, significant loss of customers and changes in the competitive environment. If an asset or asset
group is considered to be impaired, the impairment to be recognized is calculated as the amount by which the carrying amount of the asset or asset group exceeds its fair market value. Our estimates of future cash flows attributable to our
long-lived assets require significant judgment based on our historical and anticipated results and are subject to many assumptions. The estimation of fair value utilizing a discounted cash flow approach includes numerous uncertainties
which require our significant judgment when making assumptions of expected growth rates and the selection of discount rates, as well as assumptions regarding general economic and business conditions, and the structure that would yield
the highest economic value, among other factors. Refer to Note 6 "Goodwill and Intangible Assets" of the Notes of Consolidated Financial Statements for details on intangible long-lived assets.

Development Costs for Internal Use Software

Internally  developed  software  includes  enterprise-level  business  software  that  we  customize  to  meet  our  specific  operational  needs.  Such  capitalized  costs  include  external  direct  costs  utilized  in  developing  or  obtaining  the

applications and payroll and payroll-related costs for employees, who are directly associated with the development of the applications. There were no significant internally developed software costs capitalized in 2019 or 2018.

The costs to develop software that is marketed externally have not been capitalized as we believe our current software development process is essentially completed concurrent with the establishment of technological feasibility. As

such, all related software development costs are expensed as incurred and included in research and development expense in our Consolidated Statement of Operations.

Product Warranty

We offer assurance warranties on our products which provide the customer assurance that the product will function as the parties intended because it complies with agreed-upon specifications; therefore, warranties are not treated as a

separate revenue performance obligation and are accounted for as guarantees under GAAP.

Clear Aligner

We warrant our Invisalign products against material defects until the treatment plan is complete except in the case of retainers, which are warranted up to three months from expected first use. We accrue for warranty costs in cost of

net revenues upon shipment of products which is primarily based on historical experience as to product failures as well as current information on replacement costs.

Scanners and Services

We warrant our intraoral scanners for a period of one year, which include materials and labor. We accrue for these warranty costs based on average historical repair costs. An extended warranty may be purchased for additional fees.

Actual warranty costs could differ materially from the estimated amounts. We regularly review our warranty liability and update these balances based on historical warranty cost trends. 

Allowance for Doubtful Accounts

We maintain an allowance for doubtful accounts for customers that are not able to make payments. We periodically review these balances, including an analysis of the customers’ payment history and information regarding the

customers’ creditworthiness. Actual write-offs have not materially differed from the estimated allowances.

Revenue Recognition

Our revenues are derived primarily from the sale of aligners, scanners, and services from our Clear Aligner and Scanner segments. We enter into sales contracts that may consist of multiple distinct performance obligations where

certain performance obligations of the sales contract are not delivered in one reporting period. We measure and allocate revenues according to ASC 606-10, “Revenues from Contracts with Customers.”

We identify a performance obligation as distinct if both of the following criteria are met: the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer
and the entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract. Determining the standalone selling price (“SSP”), allocation of consideration from the contract to the
individual performance obligations and the appropriate timing of revenue recognition is the result of significant qualitative and quantitative judgments. While changes in the

59

 
     
allocation of the SSP between performance obligations will not affect the amount of total revenues recognized for a particular contract, any material changes could impact the timing of revenue recognition, which would have a material
effect on our financial position and result of operations. This is because the contract consideration is allocated to each performance obligation, delivered or undelivered, at the inception of the contract based on the SSP of each distinct
performance obligation.

Clear Aligner

We enter into contracts (“treatment plan(s)”) that involve multiple future performance obligations. Invisalign Comprehensive, Invisalign First, Invisalign Moderate, and Lite and Express Packages include optional additional aligners

at no charge for a certain period of time ranging from six months to five years after initial shipment, and Invisalign Go includes optional additional aligners at no charge for a period of up to two years after initial shipment.

Our treatment plans comprise the following performance obligations that also represent distinct deliverables: initial aligners, additional aligners, case refinement, and replacement aligners. We take the practical expedient to consider
shipping and handling costs as activities to fulfill the performance obligation. We allocate revenues for each treatment plan based on each unit’s SSP. Management considers a variety of factors such as historical sales, costs, and gross
margin, which may vary over time depending upon the unique facts and circumstances related to each performance obligation in making these estimates. We also consider usage rates, which is the number of times a customer is expected to
order additional aligners. Our process for estimating usage rates requires significant judgment and evaluation of inputs, including historical usage data by region, country and channel. We recognize the revenues upon shipment, as the
customers obtain physical possession and we have enforceable rights to payment. As we collect most consideration upfront, we consider whether a significant financing component exists; however, as the delivery of the performance
obligations are at the customer’s discretion, we conclude that no significant financing component exists.

Scanner

We sell intraoral scanners and CAD/CAM services through both our direct sales force and distribution partners. The intraoral scanner sales price includes one year of warranty and unlimited scanning services. The customer may also
select,  for  additional  fees,  extended  warranty  and  unlimited  scanning  services  for  periods  beyond  the  initial  year.  When  intraoral  scanners  are  sold  with  an  unlimited  scanning  service  agreement  and/or  extended  warranty,  we  allocate
revenues based on the respective SSPs of the scanner and the subscription service. We estimate the SSP of each element, taking into consideration historical prices as well as our discounting strategies. Revenues are then recognized over
time as the monthly services are rendered and upon shipment of the scanner, as that is when we deem the customer to have obtained control. Most consideration is collected upfront and in cases where there are payment plans, consideration
is collected by the one year mark and, therefore, there are no significant financing components.

Volume Discounts

In certain situations, we offer promotions in which the discount will increase depending upon the volume purchased over time. We concluded that in these situations, the promotions can represent either variable consideration or
options, depending upon the specifics of the promotion. In the event the promotion contains an option, the option is considered a material right and, therefore, included in the accounting for the initial arrangement. We estimate the average
anticipated discount over the lifetime of the promotion or contract, and apply that discount to each unit as it is sold. On a quarterly basis, we review our estimates and, if needed, updates are made and changes are applied prospectively.

Accrued Sales Return Reserve

We accrue for sales return reserve based on historical sales returns as a percentage of revenues. 

Costs to Obtain a Contract

We offer a variety of commission plans to our salesforce; each plan has multiple components. To match the costs to obtain a contract to the associated revenues, we evaluate the individual components and capitalize the eligible

components, recognizing the costs over the treatment period.

Unfulfilled Performance Obligations for Clear Aligners and Scanners

Our unfilled performance obligations, including deferred revenues and backlog, as of December 31, 2019 and the estimated revenues expected to be recognized in the future related to these performance obligations are $610.3 million.
This includes performance obligations from the Clear Aligner segment, primarily the shipment of additional aligners, which are fulfilled over six months to five years. Also included are the performance obligations from the iTero scanner
segment, primarily services and

60

support, which are fulfilled over one to five years, and contracted deliveries of additional scanners. The estimate includes both product and service unfulfilled performance obligations and the time range reflects our best estimate of when
we will transfer control to the customer and may change based on customer usage patterns, timing of shipments, readiness of customers' facilities for installation, and manufacturing availability.

Contract Balances

The timing of revenue recognition results in deferred revenues being recognized on our Consolidated Balance Sheet. For both aligners and scanners, we usually collect the total consideration owed prior to all performance obligations
being performed with payment terms generally varying from net 30 to net 180 days. Contract liabilities are recorded as deferred revenue balances, which are generated based upon timing of invoices and recognition patterns, not payments.
If the revenue recognition exceeds the billing, the exceeded amount is considered unbilled receivable and a contract asset. Conversely, if the billing occurs prior to the revenue recognition, the amount is considered deferred revenue and a
contract liability.

Shipping and Handling Costs

Shipping and handling charges to customers are included in net revenues, and the associated costs incurred are recorded in cost of net revenues.

Legal Proceedings and Litigations

We are involved in legal proceedings on an ongoing basis. If we believe that a loss arising from such matters is probable and can be reasonably estimated, we accrue the estimated loss in our consolidated financial statements. If only a
range of estimated losses can be determined, we accrue an amount within the range that, in our judgment, reflects the most likely outcome; if none of the estimates within that range is a better estimate than any other amount, we accrue the
low end of the range.

Research and Development

Research and development costs are expensed as incurred and includes the costs associated with the research and development of new products and enhancements to existing products. These costs primarily include personnel-related

costs, including payroll and stock-based compensation, outside consulting expenses and allocations of corporate overhead expenses including facilities and information technology (“IT”).

Advertising Costs

The cost of advertising and media is expensed as incurred. For the year ended December 31, 2019, 2018 and 2017, we incurred advertising costs of $119.1 million, $88.4 million and $70.1 million, respectively.

Common Stock Repurchase

We repurchase our own common stock from time to time under stock repurchase programs approved by our Board of Directors. We account for these repurchases under the accounting guidance for equity where we allocate the total

repurchase value that is in excess over par value between additional paid-in capital and retained earnings. All shares repurchased are retired.

Income Taxes

We make certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of certain tax assets and liabilities, which arise from differences in

the timing of recognition of revenues and expenses for tax and financial statement purposes.

As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves us estimating our current tax exposure
under  the  applicable  tax  laws  and  assessing  temporary  differences  resulting  from  differing  treatment  of  items  for  tax  and  accounting  purposes.  These  differences  result  in  deferred  tax  assets  and  liabilities  which  are  included  in  our
Consolidated Balance Sheet.

We account for uncertainty in income taxes pursuant to authoritative guidance based on a two-step approach to recognize and measure uncertain tax positions taken or expected to be taken in a tax return. The first step is to determine
if the weight of available evidence indicates that it is more likely than not that the tax position will be sustained on audit based on its technical merits, including resolution of any related appeals or litigation processes. The second step is to
measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. We adjust reserves for our uncertain tax

61

positions due to changing facts and circumstances, such as the closing of a tax audit or refinement of estimates due to new information. To the extent that the final outcome of these matters is different than the amounts recorded, such
differences will impact our tax provision in our Consolidated Statement of Operation in the period in which such determination is made.

We assess the likelihood that we will be able to realize our deferred tax assets. Should there be a change in our ability to realize our deferred tax assets, our tax provision would increase in the period in which we determine that it is
more likely than not that we cannot realize our deferred tax assets. We consider all available evidence, both positive and negative, including historical levels of income, expectations and risks associated with estimates of future taxable
income and ongoing prudent and feasible tax planning strategies in assessing the need for a valuation allowance. If it is more likely than not that we will not realize our deferred tax assets, we will increase our provision for taxes by
recording a valuation allowance against the deferred tax assets that we estimate will not ultimately be realizable.

The U.S. Tax Cuts and Jobs Act includes provisions for certain foreign-sourced earnings referred to as Global Intangible Low-Taxed Income (“GILTI”) which imposes a tax on foreign income in excess of a deemed return on tangible

assets of foreign corporations. We have made the election to record GILTI tax using the period cost method.

Stock-Based Compensation

We recognize stock-based compensation cost for shares expected to vest on a straight-line basis over the requisite service period of the award, net of estimated forfeitures. We use the Black-Scholes option pricing model to determine
the  fair  value  of  stock  awards  and  employee  stock  purchase  plan  shares.  We  estimate  the  fair  value  of  market-performance  based  restricted  stock  units  using  a  Monte  Carlo  simulation  model  which  requires  the  input  of  assumptions,
including expected term, stock price volatility and the risk-free rate of return. In addition, judgment is also required in estimating the number of stock-based awards that are expected to be forfeited. Forfeitures are estimated based on
historical  experience  at  the  time  of  grant  and  revised,  if  necessary,  in  subsequent  periods  if  actual  forfeitures  differ  from  those  estimates.  The  assumptions  used  in  calculating  the  fair  value  of  share-based  payment  awards  represent
management’s best estimates, but these estimates involve inherent uncertainties and the application of management’s judgment. As a result, if factors change and we use different assumptions, our stock-based compensation expense could
be materially different in the future.

Comprehensive Income

Comprehensive income includes all changes in equity during a period from non-owner sources including unrealized gains and losses on investments and foreign currency translation adjustments, net of their related tax effect.

Recent Accounting Pronouncements

(i) New Accounting Updates Recently Adopted

In May 2014, FASB released ASU 2014-09, “Revenue from Contracts with Customers,” (Topic 606) to supersede nearly all existing revenue recognition guidance under GAAP. The core principle of the standard is to recognize
revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for the goods or services. We adopted the guidance in the first quarter of fiscal year 2018 by
applying the full retrospective method. The impact of adoption was primarily related to the Clear Aligner segment. Our disaggregation of revenues can be found in Note 16 “Segments and Geographical Information.” We elected to take the
practical expedient to exclude from the transaction price all taxes assessed by a governmental authority. Prior period presentation for fiscal year 2017 has been retrospectively adjusted. The adoption of ASU 2014-09 did not have a material
impact on our Consolidated Statement of Operations, Consolidated Statement of Comprehensive Income or Consolidated Statement of Cash Flows.

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, “Leases” (Topic 842) to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on
the balance sheet and disclosing key information about leasing arrangements. The updated guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those fiscal years. In July 2018, the
FASB issued ASU 2018-11, “Leases-Targeted Improvements,” which provides an additional transition method by allowing entities to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment
to the opening balance of retained earnings. We adopted the guidance in the first quarter of fiscal year 2019 by electing the transition method issued in ASU 2018-11 and the package of practical expedients available in the standard. The
standard had a material impact on our Consolidated Balance Sheet as we recognized assets and liabilities related to our leases. The adoption did not have an impact to prior periods.

In February 2018, the FASB issued ASU 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income,” which gives entities

the option to

62

reclassify to retained earnings the tax effects resulting from the U.S. Tax Cuts and Jobs Act (the “TCJA”) related to items in accumulated other comprehensive income. The amendments are effective for fiscal years and interim periods
within those years beginning after December 15, 2018 on a retrospective basis and early adoption is permitted. We adopted the standard in the first quarter of fiscal year 2019 which did not have a material impact on our consolidated
financial statements and related disclosures. The TCJA did not affect our accumulated other comprehensive income (loss), net, and therefore we did not reclassify any income tax effects from accumulated other comprehensive income
(loss), net to our retained earnings.

(ii) Recent Accounting Updates Not Yet Effective

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses” (Topic 326) to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments
and other commitments to extend credit held by a reporting entity at each reporting date. The amendments in this update replace the existing guidance of incurred loss impairment methodology with an approach that reflects expected credit
losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. In November 2018, the FASB issued ASU 2018-19, “Codification  Improvements  to  Topic  326,  Financial
Instruments - Credit Losses” which clarifies the scope of guidance in the ASU 2016-13. The updated guidance is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. We will
adopt this standard in the first quarter of fiscal 2020 and do not expect the adoption of this standard to have a material impact on our consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” to simplify the subsequent measurement of goodwill by eliminating step two from the
goodwill impairment test. Under the amendments in this update, an entity will recognize an impairment charge for the amount by which the carrying value exceeds the fair value. The updated guidance is effective for fiscal years and
interim  periods  within  those  years  beginning  after  December  15,  2019  on  a  prospective  basis.  We  will  adopt  this  standard  in  the  first  quarter  of  fiscal  2020  and  do  not  expect  the  adoption  of  this  standard  to  have  any  impact  on  our
consolidated financial statements and related disclosures.

In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement,” to modify the disclosure requirements on fair
value measurements in Topic 820, Fair Value Measurement. The updated guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2019 on a prospective basis. We will adopt this standard in
the first quarter of fiscal 2020 and do not expect the adoption of this standard to have any impact on our consolidated financial statements and related disclosures.

In August 2018, the FASB issued ASU 2018-15, “Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40) Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a
Service Contract,” to clarify the guidance on the costs of implementing a cloud computing hosting arrangement that is a service contract. Under the amendments in this update, the entity is required to follow the guidance in Subtopic 350-
40, Internal-Use Software, to determine which implementation costs under the service contract to be capitalized as an asset and which costs to expense. The amendments are effective for fiscal years and interim periods within those years
beginning after December 15, 2019 either on a retrospective or prospective basis early adoption is permitted. We will adopt this standard in the first quarter of fiscal 2020 on a prospective basis beginning and do not expect the adoption of
this standard to have any impact on our consolidated financial statements and related disclosures.

In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes,” to enhance and simplify various aspects of the income tax accounting guidance. The amendment removes
certain  exceptions  to  the  general  principles  in  Topic  740  and  also  clarifies  and  amends  existing  guidance  to  improve  consistent  application.  The  amendments  are  effective  for  fiscal  years  and  interim  periods  within  those  fiscal  years
beginning after December 15, 2020. We are currently evaluating the impact of this guidance on our consolidated financial statements and related disclosures; however, we anticipate the adoption of the guidance will not have a material
impact to our consolidated financial statements and related disclosures.

We have no long-term marketable securities as of December 31, 2019.

Cash equivalents are not included in the tables above as the gross unrealized gains and losses are not material. We have no short-term or long-term marketable securities that have been in a continuous material unrealized loss position
for greater than twelve months as of December 31, 2019 and 2018. Amounts reclassified to earnings from accumulated other comprehensive income (loss), net related to unrealized gains or losses were not material in 2019 and 2018. For
the year ended December 31, 2019, 2018 and 2017, realized gains or losses were not material.

Our fixed-income securities investment portfolio consists of investments that can have a maximum effective maturity of up to 40 months on any individual security. The securities that we invest in are generally deemed to be low risk
based on their credit ratings from the major rating agencies. The longer the duration of these securities, the more susceptible they are to changes in market interest rates and bond yields. As interest rates increase, those securities purchased
at a lower yield show a mark-to-market unrealized loss. The unrealized losses are primarily due to changes in interest rates and credit spreads. We expect to realize the full value of all these investments upon maturity or sale. The weighted
average remaining duration of these securities was approximately seven months and four months as of December 31, 2019 and 2018, respectively.

Our investments in equity securities is considered Level 3 in the fair value hierarchy since the investments are in private companies without quoted market prices and we adjust the carrying value based on observable price changes.

The unsecured promissory note that was entered into in 2019 is classified as Level 3 in our fair value hierarchy as financial information of third parties may not be timely available and consequently we estimate the fair value based on
the best available information at the measurement date. The original amount of the note was $54.2 million which decreased over 2019 due to payments received. Refer to Note 5 “Equity Method Investments” of the Notes to Consolidated
Financial Statements for more information.

Derivative Financial Instruments

We enter into foreign currency forward contracts to minimize the short-term impact of foreign currency exchange rate fluctuations on certain trade and intercompany receivables and payables. These forward contracts are classified
within Level 2 of the fair value hierarchy. The net gain from the settlement of foreign currency forward contracts during the year ended December 31, 2019 and 2018 was $3.2 million and $9.9 million, respectively. As of December 31,
2019 and 2018, the fair value of foreign exchange forward contracts outstanding was not material.

Note 5. Equity Method Investments

On July 25, 2016, we acquired a 17% equity interest, on a fully diluted basis, in SDC for $46.7 million. Concurrently with the investment, we also entered into a supply agreement to manufacture clear aligners for SDC, which expired
on December 31, 2019. The sale of aligners to SDC and the income from the supply agreement are reported in our Clear Aligner business segment. On July 24, 2017, we purchased an additional 2% equity interest in SDC for $12.8 million.
The investment was accounted for as an equity method investment and recorded in our Consolidated Balance Sheet. We recorded our proportional share of SDC's losses within equity in losses of investee, net of tax, in our Consolidated
Statement of Operations.

As a result of the arbitrator’s decision regarding SDC announced on March 5, 2019, we were ordered to tender our SDC equity interest by April 3, 2019 for a purchase price equal to the “capital account” balance as of October 31,
2017 under the terms of the investment. In April 2019, based on the “capital account” value provided by SDC, we entered into an unsecured promissory note with SDC to receive $54.2 million through February 1, 2021 in exchange for the
tender of our membership interests. As a result, we derecognized the equity method investment balance of $38.4 million in exchange for an unsecured promissory note of $54.2 million and we recorded the difference of $15.8 million as a
gain in the second quarter of 2019 in other income in our Consolidated Statement of Operations. Although we tendered our membership interests pursuant to the arbitrator’s decision, the parties did not agree on the amount of the “capital
account” balance as of October 31, 2017 or the appropriate repurchase price for the membership units. On July 3, 2019, we filed a demand for arbitration regarding SDC’s calculation of the “capital account” balance. The arbitration
proceeding remains pending and currently is scheduled to be heard (Refer to Note 10 “Legal Proceedings” of the Notes to Consolidated Financial Statements for SDC legal proceedings discussion).

We amortize our intangible assets over their estimated useful lives. We evaluate long-lived assets, which includes property, plant and equipment and intangible assets, for impairment whenever events or changes in circumstances
indicate the carrying value of an asset may not be recoverable. The carrying value is not recoverable if it exceeds the undiscounted cash flows resulting from the use of the asset and its eventual disposition. Our estimates of future cash
flows  attributable  to  our  long-lived  assets  require  significant  judgment  based  on  our  historical  and  anticipated  results  and  are  subject  to  many  factors.  Factors  we  consider  important  which  could  trigger  an  impairment  review  include
significant negative industry or economic trends, significant loss of customers and changes in the competitive environment of our intraoral scanning business.

There were no triggering events in 2019 or 2018 that would cause impairments of our intangible long-lived assets.

Note 7. Credit Facility

On February 27, 2018, we entered into a credit facility for a $200.0 million revolving line of credit, with a $50.0 million letter of credit sublimit, and a maturity date of February 27, 2021. The credit facility requires us to comply with
specific financial conditions and performance requirements. The loans bear interest, at our option, at either a rate based on the reserve adjusted LIBOR for the applicable interest period or a base rate, in each case plus a margin. The base
rate is the highest of the credit facility’s publicly announced prime rate, the federal funds rate plus 0.50% and one month LIBOR plus 1.0%. The margin ranges from 1.25% to 1.75% for LIBOR loans and 0.25% to 0.75% for base rate
loans. Interest on the loans is payable quarterly in arrears with respect to base rate loans and at the end of an interest period (and at three month intervals if the interest period exceeds three months) in the case of LIBOR loans. Principal,
together with accrued and unpaid interest, is due on the maturity date. As of December 31, 2019, we had no outstanding borrowings under this credit facility and were in compliance with the conditions and performance requirements.

Note 8. Impairments and Other (Gains) Charges

On March 5, 2019, we announced the outcome of the arbitration regarding SDC (Refer to Note 9 “Legal Proceedings” of the Notes to Consolidated Financial Statements for SDC legal proceedings discussion) which required Align to
close its Invisalign stores and tender Align’s equity interest in SDC by April 3, 2019. Accordingly, Align evaluated the ongoing value of the Invisalign stores’ operating lease right-of-use assets and related leasehold improvements and other
fixed assets in accordance with ASC 360, Property, Plant and Equipment. Based on the evaluation, Align determined that the carrying value of these assets were not recoverable. Align evaluated the fair value of these assets in accordance
with ASC 820, Fair Value Measurement, and we considered the market participant’s ability to generate economic benefits by using these assets in its highest and best use or by selling it to another market participant that would use the asset
in its highest and best use. As a result, in the first quarter of 2019, we recorded impairment losses of $14.2 million for operating lease right-of-use assets and $14.3 million of leasehold improvements and other fixed assets. In addition, we
also recorded $1.3 million of employee severance costs and other charges. During the third quarter of 2019, we negotiated early termination of our Invisalign store leases and recorded lease termination gains of $6.8 million.

Note 9. Legal Proceedings

Securities Class Action Lawsuit

On November 5, 2018, a class action lawsuit against Align and three of our executive officers was filed in the U.S. District Court for the Northern District of California on behalf of a purported class of purchasers of our common
stock between July 25, 2018 and October 24, 2018. The complaint generally alleges claims under the federal securities laws and seeks monetary damages in an unspecified amount and costs and expenses incurred in the litigation. On
December 12, 2018, a similar lawsuit was filed in the same court on behalf of a purported class of purchasers of our common stock between April 25, 2018 and October 24, 2018 (together with the first lawsuit, the “Securities Actions”). On
May 10, 2019, the lead plaintiff filed a consolidated complaint against Align and four of our executive officers alleging similar claims as the initial complaints on behalf of a purported class of purchasers of our common stock between
April 25, 2018 and October 24, 2018. On June 24, 2019, defendants filed a motion to dismiss the consolidated complaint. On October 29, 2019, that motion to dismiss was granted with leave to amend. On November 29, 2019, the lead
plaintiff filed an amended consolidated complaint against Align and two of our executive officers alleging similar claims as the initial complaints on behalf of a purported class of purchasers of our common stock from May 23, 2018 and
October 24, 2018. Defendants’ motion to dismiss the amended consolidated complaint was filed on January 17, 2020. Align believes these claims are without merit and intends to vigorously defend itself. Align is currently unable to predict
the outcome of these lawsuits and therefore cannot determine the likelihood of loss nor estimate a range of possible loss.

Shareholder Derivative Lawsuit

In January 2019, three derivative lawsuits were filed in the U.S. District Court for the Northern District of California, purportedly on behalf of Align, naming as defendants the members of our Board of Directors along with certain of
our executive officers. The allegations in the complaints are similar to those presented in the Securities Actions, but the complaints assert various state law causes of action including for breaches of fiduciary duty, insider trading, and unjust
enrichment, among others. The complaints seek unspecified monetary damages on behalf of Align, which is named solely as a nominal defendant against whom no recovery is sought, as well as disgorgement and the costs and expenses
associated with the litigation, including attorneys’ fees. On February 26, 2019, the three lawsuits were consolidated. On April 10, 2019, the court stayed the consolidated action pending final disposition of the Securities Actions.

On April 12, 2019, a derivative lawsuit was also filed in California Superior Court for Santa Clara County, purportedly on behalf of Align, naming as defendants the members of our Board of Directors along with certain of our

executive officers. The allegations in this complaint are similar to those in the derivative suits described above. On May 16, 2019, the court stayed this action pending final disposition of the Securities Actions.

On February 22, 2019, a purported stockholder sent a letter to Align pursuant to 8 Del. C. § 220 demanding certain books and records for the stated purpose of investigating potential breaches of duty, corporate mismanagement, and
alleged  wrongdoing  by  fiduciaries  of  the  Company.  On  April  16,  2019,  Align  responded  and  refused  the  demand  on  several  legal  grounds.  On  June  10,  2019,  the  purported  stockholder  petitioned  the  Superior  Court  of  the  State  of
California, County of Santa Clara, to issue a writ of mandate commanding Align to provide the books and records requested. On August 23, 2019, Align filed a demurrer seeking to dismiss the petition, and on October 28, 2019, the Court
issued an order sustaining Align’s demurrer and dismissing the petition without an opportunity to amend. On December 19, 2019, the same purported stockholder filed a complaint in the Superior Court of California, County of Santa Clara,
seeking an order from the Court compelling Align to permit the inspection of the same books and records that were previously requested, as well as requesting attorneys’ fees. Align expects to respond to this new complaint by March 12,
2020.

Align is currently unable to predict the outcome of this demand or of these lawsuits and therefore cannot determine the likelihood of loss nor estimate a range of possible loss.

3Shape Litigation

On November 14, 2017, Align filed six patent infringement lawsuits asserting 26 patents against 3Shape, a Danish corporation, and a related U.S. corporate entity, asserting that 3Shape’s Trios intraoral scanning system and Dental
System software infringe Align patents. Align filed two Section 337 complaints with the U.S. International Trade Commission (“ITC”) alleging that 3Shape violates U.S. trade laws by selling for importation and importing its infringing
Trios intraoral scanning system and Dental System software. Align’s ITC complaints sought cease and desist orders and exclusion orders prohibiting the importation of 3Shape’s Trios scanning system and Dental System software products
into the U.S. Align also filed four separate complaints in the U.S. District Court for the District of Delaware alleging patent infringement by 3Shape’s Trios intraoral scanning system and Dental System software. Two of those cases were
stayed pending the ITC determinations, and the other two cases have been active in discovery and pretrial proceedings. Trials in the latter two cases have been rescheduled to begin on August 5, 2020 in one case

73

    
and November 30, 2020 in the other. Certain of Align’s asserted patents in the Delaware actions were found invalid by the District Court Judge. The ITC conducted hearings in the Section 337 investigations in September and November
2018. On March 1, 2019, the Administrative Law Judge issued an Initial Determination in one of the Section 337 investigations, finding no violation of Section 337 by 3Shape. On April 26, 2019, the Administrative Law Judge issued an
Initial Determination in the second Section 337 investigation, finding no violation of Section 337 by 3Shape. On August 20, 2019, the Commission vacated one Initial Determination and terminated the investigation. In the corresponding
Delaware case, the District Court lifted the stay and scheduled trial to begin on November 8, 2021. On November 22, 2019, the Commission affirmed a finding of no violation on modified grounds in the other investigation.

.
On May 9, 2018, 3Shape filed a complaint in the U.S. District Court for the District of Delaware alleging patent infringement by Align’s iTero Element scanner of a single 3Shape patent. On June 14, 2018, 3Shape filed another
complaint in the U.S. District Court for the District of Delaware alleging patent infringement by Align’s iTero Element scanner of another 3Shape patent. On August 19, 2019, the Court consolidated the two actions, and 3Shape filed an
amended complaint alleging infringement of an additional patent on August 30, 2019. Align has asserted counterclaims for patent infringement of three additional Align patents. The case is active and in the early discovery phase, with trial
scheduled to begin on April 12, 2021.

On December 10, 2018, Align filed three additional patent infringement lawsuits asserting 10  additional  patents  against  3Shape. Align  filed  one  Section  337  complaint  with  the  ITC  alleging  that  3Shape  violates  U.S.  trade  laws
through  unfair  competition  by  selling  for  importation  and  importing  the  infringing  TRIOS  intraoral  scanning  system,  Trios  Lab  Scanners  and  TRIOS  software,  TRIOS  Module  software,  Dental  System  software,  and  Ortho  System
Software. On December 11, 2018, Align filed two separate complaints in the U.S. District Court for the District of Delaware alleging patent infringement by 3Shape's Trios intraoral scanning system, Lab Scanners and Dental and Ortho
System Software. The ITC instituted the investigation, and one of the District Court cases was stayed pending the ITC determination. The remaining District Court case is in the very early stages of discovery and pretrial proceedings, and
trial has been scheduled for February 7, 2022. The ITC evidentiary hearing was held at the end of October 2019. The deadline for the Administrative Law Judge’s initial determination is March 6, 2020.

On November 5, 2019, Align filed a complaint for patent infringement asserting an additional patent against 3Shape. On January 7, 2020, Align voluntarily dismissed the suit without prejudice, and Align has instead asserted the

patent as a counterclaim in the patent infringement suit brought by 3Shape.

3Shape has sought to invalidate certain of Align’s patents through petitions for inter partes review proceedings. Align disputes 3Shape’s positions and intends to vigorously defend the validity of its patent rights.

Each of the District Court patent infringement complaints seek monetary damages and injunctive relief against further infringement.

On August 28, 2018, 3Shape filed a complaint against Align in the U.S. District Court for the District of Delaware alleging antitrust violations and seeking monetary damages and injunctive relief relating to Align’s alleged market
activities, including Align’s assertion of its patent portfolio, in alleged clear aligner and intraoral scanning markets, and the Court scheduled trial to begin on May 10, 2021. Align filed a motion to dismiss 3Shape’s complaint on October
17, 2018. Align also moved to stay the litigation pending the outcome of its motion to dismiss. The court granted Align’s motion to stay. On August 15, 2019, the Magistrate Judge recommended that Align’s motion to dismiss be granted,
and, on September 26, 2019, the District Court Judge adopted the Magistrate Judge’s Report and Recommendation, granted Align’s motion to dismiss, and dismissed 3Shape’s complaint with leave to amend within thirty days of the order.
On  October  28,  2019,  3Shape  filed  an  amended  complaint,  and  Align  again  moved  to  dismiss  the  complaint.  A  hearing  on  Align’s  motion  to  dismiss  was  held  on  February  13,  2020  before  the  magistrate  judge.  A written report and
recommendation from the magistrate judge will be forthcoming.

Align is currently unable to predict the outcome of these lawsuits and therefore cannot determine the likelihood of loss, if any, nor estimate a range of possible loss.

Simon & Simon

On March 14, 2019, a dental practice named Simon and Simon, PC d/b/a City Smiles brought an antitrust action in the United States District Court for the District of Delaware on behalf of itself and a putative class of similarly
situated practices seeking monetary damages and injunctive relief relating to Align’s alleged market activities in alleged clear aligner and intraoral scanning markets. Align filed a motion to dismiss the complaint on April 5, 2019, and the
court held a hearing on Align’s motion. On October 15, 2019, the Magistrate Judge issued a Report and Recommendation on Align’s motion to dismiss which recommends that Align’s motion be granted and that the plaintiffs’ complaint be
dismissed without prejudice. On October 29, 2019, Simon and Simon filed objections to the Magistrate Judge’s Report and Recommendation, and Align responded on November 12, 2019. Align believes

74

the plaintiffs’ claims are without merit and intends to vigorously defend itself. Align is currently unable to predict the outcome of this lawsuits and therefore cannot determine the likelihood of loss, if any, nor estimate a range of possible
loss.

SDC Dispute

In February 2018, Align received a communication on behalf of SDC Financial LLC, SmileDirectClub LLC, and the Members of SDC Financial LLC other than the Company (collectively, the “SDC Entities”) alleging that the launch
and operation of the Invisalign store pilot program constituted a breach of non-compete provisions applicable to the members of SDC Financial LLC, including Align. As a result of this alleged breach, SDC Financial LLC notified us that
its members (other than Align) sought to exercise a right to repurchase all of Align's SDC Financial LLC membership interests for a purchase price equal to the current “capital account” balance of Align. The SDC Entities’ communication
also alleged that Align breached confidentiality provisions applicable to the SDC Financial LLC members and demanded that Align cease all activities related to the Invisalign store pilot project, close existing Invisalign stores and cease
using SDC’s confidential information. In April 2018, the SDC Entities instigated confidential arbitration proceedings and filed a complaint in the Chancery Court of Davidson County, State of Tennessee that sought, among other forms of
relief, to preliminarily and permanently enjoin all activities related to the Invisalign store pilot project, require Align to close existing Invisalign stores, prohibit Align from opening any additional stores, and allow the SDC Entities to
exercise a right to repurchase all of Align's SDC Financial LLC membership interests for a purchase price equal to Align's current “capital account” balance.

On June 29, 2018, the Chancery Court of Davidson County, State of Tennessee denied the SDC Entities’ request for a temporary injunction to prevent Align from opening additional Invisalign stores. During December 2018, the
parties  participated  in  binding  arbitration  proceedings  and  presented  closing  arguments  on  January  23,  2019.  The  arbitrator  issued  his  decision  on  March  4,  2019.  The  arbitrator  found  that  Align  breached  the  non-compete  provision
applicable to the members of SDC Financial LLC and that Align misused the SDC Entities’ confidential information and violated fiduciary duties to SDC Financial LLC. The arbitrator ordered Align to close its Invisalign stores by April 3,
2019, and enjoined Align from opening new Invisalign stores or providing certain services in physical retail establishments in connection with the marketing and sale of clear aligners, and enjoined Align from using the SDC Entities’
confidential information. The arbitrator extended the expiration date of specified aspects of the non-compete provision to August 18, 2022. The arbitrator also ordered Align to tender its SDC Financial LLC membership interests to the
SDC Entities for a purchase price equal to the “capital account” balance as of October 31, 2017, to be determined in accordance with the applicable provisions of the SDC Operating Agreements. No financial damages were awarded to the
SDC Entities. The SDC Entities filed a motion to confirm the Award, which Align did not oppose, in the Circuit Court for Cook County, Illinois. The motion to confirm the Award was granted on April 29, 2019.

As required by the Award, on April 3, 2019, Align had closed its Invisalign stores, returned SDC’s alleged confidential information, and tendered its membership interests for a purchase price that SDC claims to be Align’s “capital
account” balance as of October 31, 2017. Align disputes that the SDC Entities properly determined the value of Align’s “capital account” balance as of October 31, 2017 as required by the SDC Operating Agreements and the Award.
Consequently, on July 3, 2019, Align filed a confidential demand for arbitration challenging the propriety of the SDC Entities’ determination of Align’s “capital account” balance as of October 31, 2017. That arbitration proceeding remains
pending and currently is scheduled to be heard June 23-26, 2020. Although Align expects the proper amount of its Capital Account balance as of October 31, 2017 to be determined in the course of the pending arbitration, that amount is not
capped at $97.0 million as SDC has claimed in its public filings. Relatedly, the SDC Entities filed a contempt petition with the Illinois court which confirmed the Award, asserting that Align had no right to contest the “capital account”
determination as made by the SDC Entities. On September 4, 2019, the Illinois court denied in its entirety the contempt petition filed by the SDC Entities. The SDC Entities have appealed the denial of the contempt petition, and that appeal
remains pending.

On  August  19,  2019,  the  SDC  Entities  filed  a  separate  confidential  arbitration  proceeding  alleging  that  Align  has  violated  the  non-compete  provisions  applicable  to  the  members  of  the  SDC  Entities  by  virtue  of  Align’s  alleged
dealings with a third-party claimed to be a competitor of the SDC Entities. Align has denied the claim and intends to vigorously defend itself against the newly asserted allegations. The SDC Entities have yet to identify the range of
damages they may seek to recover in the course of this arbitration and no hearing date has yet been set.

Align is currently unable to predict the outcome of these disputes and therefore cannot determine the likelihood of loss nor estimate a range of possible loss.

Straumann Group Litigation Settlement

In March 2019, Align entered into an agreement with Straumann Group to settle all outstanding patent disputes in the U.S., the U.K., and Brazil, including those involving ClearCorrect, a subsidiary of Straumann Group. Under the

terms of the settlement, Straumann Group paid Align $35.0 million on March 29, 2019. In addition, Align also signed a non-binding letter of

75

intent  with  Straumann  Group  for  a  5-year  global  development  and  distribution  agreement  whereby  Straumann  would  distribute  5,000  iTero  Element  scanners  that  would  be  fully  integrated  into  the  Straumann/Dental  Wings
CARES®/DWOS® workflow. The agreement provided that if for any reason the companies chose not to enter into the development and distribution agreement by July 2, 2019 or by a mutually agreed extended date, Straumann Group
would  pay  Align  an  additional  $16.0 million  in  lieu  of  the  development  and  distribution  agreement.  In  June  2019,  the  parties  terminated  the  discussions  regarding  a  possible  development  and  distribution  agreement  and  as  a  result,
Straumann paid us the additional $16.0 million in July 2019. In 2019, we recognized a litigation settlement gain of $51.0 million.

In addition to the above, in the course of Align’s operations, Align is involved in a variety of claims, suits, investigations, and proceedings, including actions with respect to intellectual property claims, patent infringement claims,
government  investigations,  labor  and  employment  claims,  breach  of  contract  claims,  tax,  and  other  matters.  Regardless  of  the  outcome,  these  proceedings  can  have  an  adverse  impact  on  us  because  of  defense  costs,  diversion  of
management resources, and other factors. Although the results of complex legal proceedings are difficult to predict and Align’s view of these matters may change in the future as litigation and events related thereto unfold; Align currently
does not believe that these matters, individually or in the aggregate, will materially affect Align’s financial position, results of operations or cash flows.

Note 10. Commitments and Contingencies

On November 27, 2017, we entered into a Purchase Agreement with one of our existing single source suppliers. Under the terms of the original agreement, we are required to purchase a minimum of approximately $305.2 million of
aligner materials over the next four years. On May 29, 2018, we entered into an amendment to the Purchase Agreement with the existing single source supplier to increase the original term of the agreement to five years and total minimum
purchase amount to approximately $425.9 million.

On January 15, 2019, we entered into a Purchase Agreement to purchase five floors of a building under construction in Petach Tivka, Israel for a purchase price of approximately $27.0 million with an option to purchase additional
three floors with progress payments due through 2020. During the fourth quarter of 2019, we exercised the option to purchase three additional floors and purchased one additional floor in the building for a purchase price of approximately
$24.4 million. As of December 31, 2019, we have a remaining commitment of $31.2 million which is expected to be paid in 2020.

On September 26, 2019, we entered into a Purchase and Sale Agreement to purchase a building located in San Jose, California for $21.3 million. The remaining and substantial portion of the purchase price will be paid on or before

the closing date, which is expected to occur in the first quarter of 2020.

On October 3, 2019, we entered into a Promotional Rights Agreement (the “Agreement”) for $36.0 million with a third-party which includes certain advertising and media coverage. The expense related to the Agreement will be

incurred over the period of April 1, 2020 through March 31, 2023.

Off-Balance Sheet Arrangements

As of December 31, 2019, we had no material off-balance sheet arrangements that have, or are reasonably likely to have, a current or future material effect on our consolidated financial condition, results of operations, liquidity,

capital expenditures or capital resources other than certain items disclosed in the Commitments and Contingencies section above.

Indemnification Provisions

In the normal course of business to facilitate transactions in our services and products, we indemnify certain parties: customers, vendors, lessors, and other parties with respect to certain matters, including, but not limited to, services
to be provided by us and intellectual property infringement claims made by third parties. In addition, we have entered into indemnification agreements with our directors and our executive officers that will require us, among other things, to
indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. Several of these agreements limit the time within which an indemnification claim can be made and the amount of the claim.

It is not possible to make a reasonable estimate of the maximum potential amount under these indemnification agreements due to the unique facts and circumstances involved in each particular agreement. Additionally, we have a
limited history of prior indemnification claims and the payments we have made under such agreements have not had a material adverse effect on our results of operations, cash flows or financial position. However, to the extent that valid
indemnification claims arise in the future, future payments by us could be significant and could have a material adverse effect on our results of operations or cash flows in a particular period. As of December 31, 2019, we did not have any
material indemnification claims that were probable or reasonably possible.

Note 11. Stockholders’ Equity

Common Stock

The holders of common stock are entitled to receive dividends whenever funds are legally available and when and if declared by the Board of Directors. We have never declared or paid dividends on our common stock.

Stock-Based Compensation Plans

Our 2005 Incentive Plan, as amended, provides for the granting of incentive stock options, non-statutory stock options, restricted stock units ("RSUs"), market-performance based restricted stock units ("MSUs"), stock appreciation
rights, performance units and performance shares to employees, non-employee directors and consultants. Shares granted on or after May 16, 2013 as an award of restricted stock, restricted stock unit, market-performance based restricted
stock units, performance share or performance unit ("full value awards") are counted against the authorized share reserve as one and nine-tenths (1 9/10) shares for every one (1) share subject to the award, and any shares canceled that were
counted as one and nine-tenths against the plan reserve will be returned at the same ratio. 

As of December 31, 2019, the 2005 Incentive Plan (as amended) has a total reserve of 27,783,379 shares for issuance of which 5,450,162  shares  are  available  for  issuance.  We  issue  new  shares  from  our  pool  of  authorized  but

unissued shares to satisfy the exercise and vesting obligations of our stock-based compensation plans.

Stock-Based Compensation

Stock-based compensation is based on the estimated fair value of awards, net of estimated forfeitures, and recognized over the requisite service period. Estimated forfeitures are based on historical experience at the time of grant and
may be revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The stock-based compensation related to all of our stock-based awards and employee stock purchase plan for the year ended December 31,
2019, 2018 and 2017 is as follows (in thousands):

We have not granted options since 2011 and all outstanding options were fully vested and associated stock-based compensation expense was recognized as of December 31, 2015. During the year ended December 31, 2019, 8,187

stock options were exercised at a weighted average exercise price of $8.07 per share. As of December 31, 2019, there were no options outstanding and exercisable.

The aggregate intrinsic value represents the total pre-tax intrinsic value (the difference between our closing stock price on the last trading day in 2019 and the exercise price, multiplied by the number of in-the-money options) that
would have been received by the option holders had all option holders exercised their options on the last trading day of 2019. This amount will fluctuate based on the fair market value of our stock. The total intrinsic value of stock options
exercised for the year ended December 31, 2019, 2018 and 2017 was $2.0 million, $17.6 million and $18.1 million respectively.

received by the unit holders had all RSUs been vested and released as of the last trading day of 2019. This amount will fluctuate based on the fair market value of our stock. During 2019, of the 442,524 shares vested and released, 141,543
shares vested were withheld for employee statutory tax obligations, resulting in a net issuance of 300,981 shares.

The total intrinsic value of RSUs vested and released during 2019, 2018 and 2017 was $112.4 million, $146.7 million and $99.5 million, respectively. The total fair value of RSUs vested during the year ended December 31, 2019,
2018  and  2017  was  $46.8  million,  $42.2  million  and  $46.2  million,  respectively.  The  weighted  average  grant  date  fair  value  of  RSUs  granted  during  2019,  2018  and  2017  was  $255.42,  $262.58  and  $118.77  respectively.  As  of
December 31, 2019, there was $88.7 million of total unamortized compensation costs, net of estimated forfeitures, related to RSUs and these costs are expected to be recognized over a weighted average period of 2.0 years.

Market-Performance Based Restricted Stock Units ("MSUs")

We grant MSUs to our executive officers. Each MSU represents the right to one share of Align’s common stock. The actual number of MSUs which will be eligible to vest will be based on the performance of Align’s stock price
relative to the performance of a stock market index over the vesting period, and certain MSU grants are also based on Align's stock price at the end of the performance period. Generally, the vesting period of MSUs is three years. For
MSUs granted during the year ended December 31, 2019, the maximum number of MSUs which will be eligible to vest are 250% of the MSUs initially granted.

The following table summarizes the MSU performance for the year ended December 31, 2019:

shares were withheld for tax payments, resulting in a net issuance of 102,884 shares.

The total intrinsic value of MSUs vested and released during 2019, 2018 and 2017 was $47.7 million, $92.7 million and $28.8 million, respectively. The total fair value of MSUs vested during the year ended December 31, 2019, 2018
and 2017 was $14.8 million, $19.5 million and $15.0 million, respectively. As of December 31, 2019, we expect to recognize $36.2 million of total unamortized compensation cost, net of estimated forfeitures, related to MSUs over a
weighted average period of 1.1 years.

respectively, and are reflected as a financing activity in the Consolidated Statement of Cash Flows.

Employee Stock Purchase Plan ("ESPP")

In May 2010, our stockholders approved the 2010 Employee Stock Purchase Plan (the “2010 Purchase Plan”), which consists of consecutive overlapping twenty-four month offering periods with four six-month purchase periods in
each offering period. Employees purchase shares at 85% of the lower of the fair market value of the common stock at either the beginning of the offering period or the end of the purchase period. The 2010 Purchase Plan will continue until
terminated by either the Board of Directors or its administrator. The maximum number of shares available for purchase under the 2010 Purchase Plan is 2.4 million shares. In June 2019, the 2010 Purchase Plan was amended to include a
non-Code Section 423 component to grant purchase rights to employees outside the U.S. and Canada with six-month offering periods and purchase periods.

there was $9.9 million of total unamortized compensation costs related to future employee stock purchases which we expect to be recognized over a weighted average period of 0.9 year.

Note 12. Common Stock Repurchase Programs

April 2014 Repurchase Program

In April 2014, we announced that our Board of Directors had authorized a plan to repurchase up to $300.0 million of our common stock ("April 2014 Repurchase Program").

79

available for repurchase under the May 2018 Repurchase Program.

Note 13. Employee Benefit Plans

We have defined contribution retirement plan under Section 401(k) of the Internal Revenue Code for our U.S. employees which covers substantially all U.S. employees who meet minimum age and service requirements and allows
participants to defer a portion of their annual compensation on a pre-tax basis. We match 50% of our employee’s salary deferral contributions up to a 6% of the employee’s eligible compensation. We contributed approximately $6.2 million,
$5.2 million and $4.3 million to the 401(k) plan during the year ended December 31, 2019, 2018 and 2017, respectively.

The TCJA was enacted into law on December 22, 2017 and made significant changes to the Internal Revenue Code, including, but not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after
December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31,
2017.

On  December  22,  2017,  Staff  Accounting  Bulletin  No.  118  ("SAB  118")  was  issued  to  address  the  application  of  GAAP  in  situations  when  a  registrant  does  not  have  the  necessary  information  available,  prepared,  or  analyzed
(including computations) in reasonable detail to complete the accounting for certain income tax effects of the TCJA. As of December 31, 2017, we recorded a provisional tax charge for the estimated impact of the TCJA of $84.3 million, of
which $73.9 million was related to a provisional transition tax liability on the mandatory deemed repatriation of foreign earnings and $10.4 million was related to the remeasurement of certain deferred tax assets and liabilities. We finalized
our assessment of the impact of the TCJA on our 2017 financial statements and recorded additional charges of $3.0 million in 2018, all of which relate to the transition tax on the mandatory deemed repatriation of foreign earnings.

As of December 31, 2019, undistributed earnings of our foreign subsidiaries totaled $452.6 million and substantially all of the earnings previously determined to be not indefinitely reinvested have been repatriated. Under the GILTI
provisions of the TCJA, U.S. income taxes have already been provided on the $452.6 million undistributed earnings that is indefinitely reinvested in our international operations, therefore, the tax impact upon distribution is limited to
mainly state income and withholding taxes and is not significant.

The available positive evidence at December 31, 2019 included historical operating profits and a projection of future income sufficient to realize most of our remaining deferred tax assets. As of December 31, 2019, it was considered

more likely than not that our deferred tax assets would be realized with the exception of certain capital loss carryovers as we are unable to forecast sufficient future profits to realize the deferred tax assets.

The total valuation allowance as of December 31, 2019 as well as the increase for the year 2019 was not material to our financial statements.

As  of  December  31,  2019,  we  have  foreign  net  operating  loss  carryforwards  of  approximately  $82.1 million,  the  majority  of  which  can  be  carried  forward  indefinitely,  and  a  minor  portion  of  which,  if  not  utilized,  will  expire

beginning after 2024.

In the event of a change in ownership, as defined under federal and state tax laws, our tax credit carryforwards may be subject to annual limitations. The annual limitations may result in the expiration of the tax credit carryforwards

before utilization.

The total amount of gross unrecognized tax benefits as of December 31, 2019 was $46.7 million, of which $43.9 million would impact our effective tax rate if recognized.

We file U.S. federal, U.S. state, and non-U.S. income tax returns. Our major tax jurisdictions include U.S. federal, the State of California and the Netherlands. For U.S. federal and state tax returns, we are no longer subject to tax
examinations for years before 2015. We are currently under examination by the Internal Revenue Service for tax years 2015 and 2016. With few exceptions, we are no longer subject to examination by foreign tax authorities for years
before 2012.

We have elected to recognize interest and penalties related to unrecognized tax benefits as a component of income taxes. Interest and penalties included in tax expense for the year ended December 31, 2019 and 2018 as well as
accrued as of December 31, 2019 and 2018 was not material to our financials. The timing and resolution of income tax examinations is uncertain, and the amounts ultimately paid, if any, upon resolution of issues raised by the taxing
authorities may differ materially from the amounts accrued for each year. Although it is possible that our balance of gross unrecognized tax benefits could materially change in the next 12 months, given the uncertainty in the development
of ongoing income tax examinations, we are unable to estimate the full range of possible adjustments to this balance.

Subsequent to the year ended December 31, 2019, we completed an intra-entity transfer of certain intellectual property rights and fixed assets to our new Swiss subsidiary, where our EMEA regional headquarters is now located
beginning January 1, 2020. The transfer of intellectual property rights did not result in a taxable gain; however, it did result in a step-up of the Swiss tax deductible basis in the transferred assets, and accordingly, created a temporary
difference  between  the  book  basis  and  the  tax  basis  of  such  intellectual  property  rights.  Consequently,  this  transaction  will  result  in  the  recognition  of  a  deferred  tax  asset  and  related  one-time  tax  benefit  of  up  to  $1.6 billion,  in  our
consolidated  financial  statements  during  the  three  months  ending  March  31,  2020.  We  continue  to  assess  the  realizability  of  this  deferred  tax  asset  as  we  take  into  account  new  information,  including  the  profitability  of  our  Swiss
headquarters and ongoing communication with the Swiss tax authorities. Effective January 1, 2020, Switzerland will become a major tax jurisdiction owing to the relocation of our EMEA regional headquarters from the Netherlands.

Note 15. Net Income per Share

Basic net income per share is computed using the weighted average number of shares of common stock outstanding during the period. Diluted net income per share is computed using the weighted average number of shares of

common stock, adjusted for any dilutive effect of potential common stock. Potential common stock, computed using the treasury stock method, includes RSUs, MSUs and our ESPP.

The following table sets forth the computation of basic and diluted net income per share attributable to common stock (in thousands, except per share amounts):

Note 17. Segments and Geographical Information

Segment Information

Operating  segments  are  defined  as  components  of  an  enterprise  for  which  separate  financial  information  is  available  that  is  evaluated  regularly  by  the  Chief  Operating  Decision  Maker  (“CODM”),  or  decision-making  group,  in

deciding how to allocate

resources and in assessing performance. Our CODM is our Chief Executive Officer. We report segment information based on the management approach. The management approach designates the internal reporting used by CODM for
decision  making  and  performance  assessment  as  the  basis  for  determining  our  reportable  segments.  The  performance  measures  of  our  reportable  segments  include  net  revenues,  gross  profit  and  income  from  operations.  Income  from
operations for each segment includes all geographic revenues, related cost of net revenues and operating expenses directly attributable to the segment. Certain operating expenses are attributable to operating segments and each allocation is
measured differently based on the specific facts and circumstances of the costs being allocated. Costs not specifically allocated to segment income from operations include various corporate expenses such as stock-based compensation and
costs related to IT, facilities, human resources, accounting and finance, legal and regulatory, and other separately managed general and administrative costs outside the operating segments.

We group our operations into two reportable segments: Clear Aligner segment and Scanner segment.

• Our Clear Aligner segment consists of Comprehensive Products, Non-Comprehensive Products and Non-Case revenues as defined below:

•
•

•

Comprehensive Products include Invisalign Comprehensive and Invisalign First.
Non-Comprehensive Products include, but are not limited to, Invisalign Moderate, Lite and Express packages and Invisalign Go, in addition to revenues from the sale of aligners to SmileDirectClub (“SDC”) under our supply
agreement that expired on December 31, 2019.
Non-Case includes, but not limited to, Vivera retainers along with our training and ancillary products for treating malocclusion. 

• Our Scanner segment consists of intraoral scanning systems, which includes a single hardware platform and restorative or orthodontic software options, additional services and ancillary products. This segment includes our iTero

scanner and OrthoCAD services.

These reportable operating segments are based on how our CODM views and evaluates our operations as well as allocation of resources. The following information relates to these segments (in thousands):

DESCRIPTION OF THE CAPITAL STOCK OF ALIGN TECHNOLOGY, INC.

The following description of the material provisions of the capital stock and other material terms of the amended and restated certificate of incorporation (“Certificate”) and bylaws of Align Technology, Inc. (the “Company”) and certain
provisions of Delaware law, are summaries only. These summaries do not purport to be complete and are qualified in their entirety by reference to the Company’s Certificate, bylaws, and by the provisions of applicable law.

Authorized Capital
The Company’s authorized capital stock consists of 200,000,000 shares of common stock, $.0001 par value per share (“Common Stock”) and 5,000,000 shares of undesignated Preferred Stock, $.0001 par value per share (“Preferred
Stock”).

Common Stock
Voting. Except as otherwise required by Delaware law, as specifically set forth in the provisions of the Company’s Certificate, including any express terms of the Preferred Stock and any series thereof or the bylaws, at every annual or
special meeting of stockholders, every holder of Common Stock is entitled to one vote per share. When a quorum is present, the affirmative vote of the holders of the shares representing a majority of the voting power at the meeting and
entitled to vote on the subject matter shall be the act of the stockholders, unless the question is one upon which by express provisions of an applicable law or of the Company’s Certificate or bylaws a different vote is required, in which case
such express provision shall govern and control.

Dividends Rights. Subject to the rights of holders of any then outstanding shares of the Company’s Preferred Stock (discussed below), holders of Common Stock are entitled to receive ratably any dividends that may be declared by the
Company’s Board of Directors (the “Board”) out of funds legally available therefor.

Liquidation Rights. In the event of the Company’s liquidation, dissolution or winding up, holders of Common Stock are entitled to share ratably in all assets available for distribution to stockholders after the payment of or provision for all
of the Company’s debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any then outstanding shares of preferred stock.

Other Rights. Holders of Common Stock do not have preemption, conversion or redemption rights. The rights, preferences and privileges of holders of Common Stock will be subject to those of the holders of any shares of the Company’s
preferred stock the Company may issue in the future.

Listing. The Common Stock is listed on NASDAQ under the ticker symbol “ALGN."

Transfer Agent and Registrar. The transfer agent and registrar for the Common Stock is Computershare, Inc.

Preferred Stock
There  are  currently  no  shares  of  Preferred  Stock  outstanding,  and  the  Company  has  no  present  plans  to  issue  any.  However,  under  the  terms  of  the  Certificate,  the  Board  has  the  authority,  without  further  action  by  the  Company’s
stockholders, to issue the following classes of Preferred Stock:

Undesignated Preferred Stock. The Board may issue not more than an aggregate of 5,000,000 shares of undesignated Preferred Stock in one or more series, without stockholder approval, and to establish, from time to time, the number of
shares to be included in each series of Preferred Stock, to fix the designation, powers, preferences, and rights of the shares of each series of Preferred Stock, and to specify any qualifications, limitations or restrictions.

Subject to the rights of holders of any outstanding shares of Preferred Stock holding prior or superior rights and except as otherwise required by Delaware law, or as specifically set forth in the provisions of the Certificate or bylaws, the
Board may grant holders of Preferred Stock or any series thereof:

Dividend Rights. Rights to dividends as declared by the Board out of funds legally available different from and/or in addition to those of the holders of Common Stock, including the amounts payable on, preferences in respect of

any series of Preferred Stock, whether any dividends are or are not cumulative and the dates on which dividends may be payable;

Voting Rights. Voting rights at every annual or special meeting of stockholders different from or consistent with those of the holders of Common Stock or any other series of Preferred Stock;

Liquidation Rights. Preferential liquidation rights in the event of the Company’s liquidation, dissolution or winding up different from or consistent with those of the holders of Common Stock or any other series of Preferred Stock;

Conversion or Exchange. Rights in regard of the conversion or exchange of Preferred Stock into shares of any other class or series or other security, including the price(s), date(s) and other terms and condition of conversion;

Redemption. Rights of redemption different from or consistent with those of the holders of Common Stock or any series of Preferred Stock; and

Other Rights. Other rights restricting the issuance of additional shares of the same series or of any other class or series.

The purpose of authorizing the Board to issue Preferred Stock and determine its rights and preferences is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of Preferred Stock, while providing
flexibility in connection with possible acquisitions, future financings and other corporate purposes, could make it more difficult for a third party to acquire control of the Company, or could adversely affect the rights of the Company’s
common stockholders.

Board of Directors
The Board is not classified and there is no cumulative voting in the election of directors. The number of directors serving on the Board may be changed by a resolution adopted by the affirmative vote of a majority of the directors then in
office.

Anti-Takeover Effects of Certain Provisions of Delaware Law, the Certificate of Incorporation and the Bylaws
The Certificate and bylaws contain provisions that are intended to enhance the likelihood of continuity and stability in the composition of the Board and that could make it more difficult to acquire control of the Company by means of a
tender offer, open market purchases, a proxy contest or otherwise. The Company expects that these provisions, which are summarized below, will discourage coercive takeover practices or inadequate takeover bids. These provisions are
also designed to encourage persons seeking to acquire control of the Company to first negotiate with the Board, which the Company believes may result in an improvement of the terms of any such acquisition in favor of the Company’s
stockholders. However, they also give the Board the power to discourage acquisitions that some stockholders may favor. A description of these provisions is set forth below.

No  Cumulative  Voting.  Under  Delaware  law,  the  right  to  vote  cumulatively  does  not  exist  unless  the  certificate  of  incorporation  specifically  authorizes  cumulative  voting.  The  Certificate  does  not  grant  stockholders  the  right  to  vote
cumulatively; therefore stockholders holding a majority of the shares of Common Stock outstanding will be able to elect all of the Company’s directors.

Stockholder Action by Written Consent and Special Meetings of Stockholders. The Certificate and bylaws provide that all stockholder action must be affected at a duly called meeting of stockholders and not by written consent, and that
only the Chairperson of the Board, the chief executive officer or the president may call a special meeting of stockholders.

Requirements for Advance Notification of Stockholder Meetings, Nominations and Proposals. The Company’s bylaws include an advance notice procedure for stockholder proposals to be brought before an annual meeting of stockholders,
including proposed nominations of candidates for election to the Board. Stockholders at an annual meeting will only be able to consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the
direction of the Board, or by a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has delivered timely written notice in proper form to the Company’s secretary of the stockholder’s
intention to bring such business before the meeting. These provisions could have the effect of delaying stockholder actions until the next stockholder meeting that are favored by the holders of a majority of the Company’s outstanding
voting securities or may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempt to obtain control of the Company.

Super-Majority Voting. The Certificate requires a 66-2/3% stockholder vote to amend, repeal or modify certain of its provisions and bylaws relating to the size, nomination, election and appointment of members to Board, the requirement
that stockholder actions be effected at a duly called meeting and the designated parties entitled to call a special meeting of the stockholders. In addition, the authorization of blank check Preferred Stock makes it possible for the Board to
issue Preferred Stock with voting or other rights or preferences that could impede the success of any attempt to change control of the Company.

Delaware Takeover Statute
The Company is subject to the provisions of Section 203 of the General Corporation Law of the State of Delaware. Subject to certain exceptions, Section 203 of the Delaware General Corporation Law prohibits a Delaware corporation
from engaging in any "business combination" with any "interested stockholder" for a period of three years after the date of the transaction in which the person or entity became an interested stockholder. A "business combination" includes
certain mergers, asset sales or other transactions resulting in a financial benefit to the interested stockholder. Subject to various exceptions, an "interested stockholder" is a person who, together with his or her affiliates and associates, owns,
or within the past three years has owned, 15% or more of our outstanding voting stock. This provision could discourage mergers or other takeover or change in control attempts, including attempts that might result in the payment of a
premium over the market price for shares of the Common Stock.

Exhibit 10.3

ALIGN TECHNOLOGY, INC.

AMENDED AND RESTATED 2005 INCENTIVE PLAN
EXHIBIT A

OFFICER APPOINTED AFTER SEPTEMBER 2016

RESTRICTED STOCK UNIT AGREEMENT

1.    Grant. The Company hereby grants to Participant under the Plan an Award of Restricted Stock Units, subject to all of the terms and conditions in the Notice of Grant, this Agreement and

the Plan.

2.    Company’s Obligation to Pay. Each Restricted Stock Unit represents a value equal to the Fair Market Value of a Share on the date it becomes vested. Unless and until the Restricted Stock
Units will have vested in the manner set forth in Sections 3 and 4, Participant will have no right to payment of any such Restricted Stock Units. Prior to actual payment of any vested Restricted Stock
Units, such Restricted Stock Unit will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company.

3.    Vesting Schedule. Subject to Section 4, the Restricted Stock Units awarded by this Agreement will vest in Participant according to the vesting schedule set forth on the attached Notice of
Grant, subject to Participant continuing to be a Service Provider through each such date; provided, however, that the paragraph (c) of the Notice of Grant shall apply in the event Participant ceases to
be  a  Service  Provider  within  18  months  of  a  Change  of  Control  (as  defined  in  the  employment  agreement  between  the  Company  and  Participant  (the  “Employment  Agreement”))  as  a  result  of
termination by the Company without Cause (as defined in the Employment Agreement) or if Participant resigns for Good Reason (as defined in the Employment Agreement).

4.    Forfeiture upon Termination of Status as a Service Provider. Subject to paragraphs (c) of the Notice of Grant, if Participant ceases to be a Service Provider for any or no reason, the then-

unvested Restricted Stock Units awarded by this Agreement will thereupon be forfeited at no cost to the Company and Participant will have no further rights thereunder.

5.    Payment after Vesting. Any Restricted Stock Units that vest in accordance with Section 3 will be paid to Participant (or in the event of Participant’s death, to his or her estate) in whole

Shares, subject to Participant satisfying any applicable tax withholding obligations as set forth in Section 7.

6.    Payments after Death. Any distribution or delivery to be made to Participant under this Agreement will, if Participant is then deceased, be made to Participant’s designated beneficiary, or
if no beneficiary survives Participant, the administrator or executor of Participant’s estate. Any such transferee must furnish the Company with (a) written notice of his or her status as transferee, and
(b) evidence satisfactory to the Company to establish the validity of the transfer and compliance with any laws or regulations pertaining to said transfer.

7.    Taxes.

(a)    Generally. The Participant is ultimately liable and responsible for all taxes owed in connection with the Restricted Stock Units, regardless of any action the Company or any of its
Subsidiaries takes with respect to any tax withholding obligations that arise in connection with the Restricted Stock Units. Neither the Company nor any of its Subsidiaries makes any representation
or undertaking regarding the treatment of any tax withholding in connection with the grant or vesting of the Restricted Stock Units or the subsequent sale of Shares issuable pursuant to the Restricted
Stock Units. The Company and its Subsidiaries do not commit and are under no obligation to structure the Restricted Stock Units to reduce or eliminate the Participant’s tax liability.

(b)    Payment of Withholding Taxes. Notwithstanding any contrary provision of this Agreement, no Shares will be issued to the Participant, unless and until satisfactory arrangements
(as determined by the Administrator) will have been made by the Participant with respect to the payment of any taxes which the Company determines must be withheld with respect to the Restricted
Stock Units. The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to time, may satisfy such tax withholding obligations, in whole or in part, by
withholding otherwise deliverable Shares having an aggregate Fair Market Value sufficient to (but not exceeding) the minimum amount required to be withheld. In addition and to the maximum
extent permitted by law, the Company has the right to retain without notice from salary or other amounts payable to the Participant, cash having a value sufficient to satisfy any tax withholding
obligations that cannot be satisfied by the withholding of otherwise deliverable Shares.

8.    Rights as Stockholder. Neither Participant nor any person claiming under or through Participant will have any of the rights or privileges of a stockholder of the Company in respect of any
Shares deliverable hereunder, unless and until certificates representing such Shares will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to
Participant.

9.    No Effect on Service. Participant acknowledges and agrees that the vesting of the Restricted Stock Units pursuant to Section 3 hereof is earned only by Participant continuing to be a
Service Provider through the applicable vesting dates (and not through the act of being hired or acquiring Shares hereunder) (subject, however, to paragraphs (c) and (d) of the Notice of Grant).
Participant further acknowledges and agrees that this Agreement, the transactions contemplated hereunder and the vesting schedule set forth herein do not constitute an express or implied promise of
Participant continuing to be a Service Provider for the vesting period, for any period, or at all, and will not interfere with the Participant’s right or the right of the Company (or the Affiliate employing
or retaining Participant) to terminate Participant as a Service Provider at any time, with or without cause.

10.        Address  for  Notices.  Any  notice  to  be  given  to  the  Company  under  the  terms  of  this  Agreement  will  be  addressed  to  the  Company,  in  care  of  Stock  Administrator  at  Align

Technology, Inc., 2560 Orchard Parkway, San Jose, CA 95131, or at such other address as the Company may hereafter designate in writing.

11.    Grant is Not Transferable. Except  to  the  limited  extent  provided  in  Section  6,  this  grant  and  the  rights  and  privileges  conferred  hereby  will  not  be  transferred,  assigned,  pledged  or
hypothecated in any way (whether by operation of law or otherwise) and will not be subject to sale under execution, attachment or similar process. Upon  any  attempt  to  transfer,  assign,  pledge,
hypothecate or otherwise dispose of this grant, or any right or privilege conferred hereby, or upon any attempted sale under any execution, attachment or similar process, this grant and the rights and
privileges conferred hereby immediately will become null and void.

12.    Binding Agreement. Subject to the limitation on the transferability of this grant contained herein, this Agreement will be binding upon and inure to the benefit of the heirs, legatees, legal

representatives, successors and assigns of the parties hereto.

13.    Additional Conditions to Issuance of Stock. If at any time the Company will determine, in its discretion, that the listing, registration or qualification of the Shares upon any securities
exchange or under any state or federal law, or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of shares to Participant (or his
estate),  such  issuance  will  not  occur  unless  and  until  such  listing,  registration,  qualification,  consent  or  approval  will  have  been  effected  or  obtained  free  of  any  conditions  not  acceptable  to  the
Company. Where  the  Company  determines  that  the  delivery  of  the  payment  of  any  Shares  will  violate  federal  securities  laws  or  other  applicable  laws,  the  Company  will  defer  delivery  until  the
earliest date at which the Company reasonably anticipates that the delivery of Shares will no longer cause such violation. The Company will make all reasonable efforts to meet the requirements of
any such state or federal law or securities exchange and to obtain any such consent or approval of any such governmental authority.

14.    Plan Governs. This Agreement is subject to all terms and provisions of the Plan. In the event of a conflict between one or more provisions of this Agreement and one or more provisions

of the Plan, the provisions of the Plan will govern.

15.    Administrator Authority. The Administrator will have the power to interpret the Plan and this Agreement and to adopt such rules for the administration, interpretation and application of
the Plan as are consistent therewith and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any Restricted Stock Units have vested). All actions
taken and all interpretations and determinations made by the Administrator in good faith will be final and binding upon Participant, the Company and all other interested persons. No member of the
Administrator will be personally liable for any action, determination or interpretation made in good faith with respect to the Plan or this Agreement.

16.    Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related to Restricted Stock Units awarded under the Plan or future Restricted Stock Units
that may be awarded under the Plan by electronic means or request Participant’s consent to participate in the Plan by electronic means. Participant hereby consents to receive such documents by
electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated by the Company.

17.    Captions. Captions provided herein are for convenience only and are not to serve as a basis for interpretation or construction of this Agreement.

18.        Agreement  Severable.  In  the  event  that  any  provision  in  this  Agreement  will  be  held  invalid  or  unenforceable,  such  provision  will  be  severable  from,  and  such  invalidity  or

unenforceability will not be construed to have any effect on, the remaining provisions of this Agreement.

19.    Governing Law. This Award Agreement shall be governed by the laws of the State of California, without giving effect to the conflict of law principles thereof. For purposes of litigating
any  dispute  that  arises  under  this  Award  of  Restricted Stock Units  or  this  Agreement,  the  parties  hereby  submit  to  and  consent  to  the  jurisdiction  of  the  State  of  California,  and  agree  that  such
litigation shall be conducted in the courts of Santa Clara County, California, or the federal courts for the United States for the Northern District of California, and no other courts, where this Award of
Restricted Stock Units is made and/or to be performed.

[Remainder of Page Intentionally Left Blank]

EXHIBIT A

RESTRICTED STOCK UNIT AGREEMENT

1.

Grant. The Company hereby grants to Participant under the Plan an Award of Restricted Stock Units (referred to in the Plan as Restricted Stock Units), subject to all of the terms and conditions in the Notice of Grant,

this Agreement and the Plan.

2.

Company’s Obligation to Pay. Each Restricted Stock Unit represents a value equal to the Fair Market Value of a Share on the date it becomes vested. Unless and until the Restricted Stock Units will have vested in the
manner set forth in Sections 3 and 4, Participant will have no right to payment of any such Restricted Stock Units. Prior to actual payment of any vested Restricted Stock Units, such Restricted Stock Unit will represent an unsecured
obligation of the Company, payable (if at all) only from the general assets of the Company.

3.

Vesting Schedule. Subject to Section 4, the Restricted Stock Units awarded by this Agreement will vest in, and the underlying award shares will be issued to, Participant according to the vesting/issuance schedule set

forth in paragraph (a) of the attached Notice of Grant, subject to paragraphs (b)-(d) of such Notice of Grant.

4.

Forfeiture upon Termination of Status as a Service Provider. Subject to paragraphs (a) through (d) of the attached Notice of Grant, if Participant ceases to be a Service Provider for any or no reason, any then-unvested
Restricted Stock Units awarded by this Agreement will thereupon be forfeited at no cost to the Company and Participant will have no further rights thereunder, in each case unless otherwise determined by the Board or the Compensation
Committee acting as the Plan Administrator.

5.

Payment after Vesting. Any Restricted Stock Units that vest in accordance with Section 3 will be paid to Participant (or in the event of Participant’s death, to his or her estate) in whole Shares, subject to Participant
satisfying any applicable tax withholding obligations as set forth in Section 7. Subject to the provisions of Section 19, any Shares will be issued to Participant as soon as practicable on or after the relevant vesting date, but in any event,
within the period ending on the later to occur of the date that is two-and-one-half months from the end of (a) Participant’s tax year that includes the vesting date, or (b) the Company’s tax year that includes the vesting date.

6.

Payments after Death. Any distribution or delivery to be made to Participant under this Agreement will, if Participant is then deceased, be made to Participant’s designated beneficiary, or if no beneficiary survives
Participant, the administrator or executor of Participant’s estate. Any such transferee must furnish the Company with (a) written notice of his or her status as transferee, and (b) evidence satisfactory to the Company to establish the validity
of the transfer and compliance with any laws or regulations pertaining to said transfer.

7.

Taxes.

(a)    Generally. The Participant is ultimately liable and responsible for all taxes owed in connection with the Restricted Stock Units, regardless of any action the Company or any of its Subsidiaries takes with respect to
any  tax  withholding  obligations  that  arise  in  connection  with  the  Restricted  Stock  Units.  Neither  the  Company  nor  any  of  its  Subsidiaries  makes  any  representation  or  undertaking  regarding  the  treatment  of  any  tax  withholding  in
connection with the grant or vesting of the Restricted Stock Units or the subsequent sale of Shares issuable pursuant to the Restricted Stock Units. The Company and its Subsidiaries do not commit and are under no obligation to structure
the Restricted Stock Units to reduce or eliminate the Participant’s tax liability.

(b)    Payment of Withholding Taxes. Notwithstanding any contrary provision of this Agreement, no Shares will be issued to the Participant, unless and until satisfactory arrangements (as determined by the Administrator)
will have been made by the Participant with respect to the payment of any taxes which the Company determines must be withheld with respect to the Restricted Stock Units. The Administrator, in its sole discretion and pursuant to such
procedures as it may specify from time to time, may satisfy such tax withholding obligations, in whole or in part, by withholding otherwise deliverable Shares having an aggregate Fair Market Value sufficient to (but not exceeding) the
minimum amount required to be withheld. In addition and to the maximum extent permitted by law, the Company has the right to retain without notice from salary or other amounts payable to the Participant, cash having a value sufficient
to satisfy any tax withholding obligations that cannot be satisfied by the withholding of otherwise deliverable Shares.

Rights as Stockholder. Neither Participant nor any person claiming under or through Participant will have any of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder,
unless and until certificates representing such Shares will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to Participant, provided that the Participant shall be entitled to any award

8.

    
adjustments provided pursuant to Section 18(a) of the Plan.

9.

No Effect on Service. Participant  acknowledges  and  agrees  that  the  vesting  of  the  Restricted  Stock  Units  pursuant  to  Section  3  hereof  is  earned  only  by  Participant  continuing  to  be  a  Service  Provider  through  the
applicable vesting dates (and not through the act of being hired or acquiring Shares hereunder) (subject, however, to paragraphs (a) through (d) of the Notice of Grant). Participant further acknowledges and agrees that this Agreement, the
transactions contemplated hereunder and the vesting schedule set forth herein do not constitute an express or implied promise of Participant continuing to be a Service Provider for the vesting period, for any period, or at all, and will not
interfere with the Participant’s right or the right of the Company (or the Affiliate employing or retaining Participant) to terminate Participant as a Service Provider at any time, with or without cause.

10.

Address for Notices. Any notice to be given to the Company under the terms of this Agreement will be addressed to the Company, in care of Stock Administrator at Align Technology, Inc., 881 Martin Avenue, Santa
Clara, CA 95050, or at such other address as the Company may hereafter designate in writing. Any notice to be given to the Participant regarding his Restricted Stock Unit award shall comply with the notice provisions in the Participant’s
CEO Employment Agreement.

11.

Grant is Not Transferable. Except to the limited extent provided in Section 6, or, in the event of Participant’s death, by his will or the laws of descent or distribution (pursuant to Section 15 of the Plan) or as otherwise
determined by the Plan Administrator (pursuant to Section 15 of the Plan), this grant and the rights and privileges conferred hereby will not be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or
otherwise) and will not be subject to sale under execution, attachment or similar process. Upon any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of this grant, or any right or privilege conferred hereby, or upon any
attempted sale under any execution, attachment or similar process, this grant and the rights and privileges conferred hereby immediately will become null and void. Notwithstanding the above, the rights relating to Participant’s Restricted
Stock Unit grant can be exercised on the Participant’s behalf by his legal representative in the event of his legal incapacity, or, in the event of his death, by his designated beneficiary (if any) or, if no beneficiary is designated with respect to
his Restricted Stock Units, by his estate.

12.

Binding Agreement. Subject to the limitation on the transferability of this grant contained herein, this Agreement will be binding upon and inure to the benefit of the heirs, legatees, legal representatives, successors and

assigns of the parties hereto.

13.

Additional Conditions to Issuance of Stock. If at any time the Company will determine, in its discretion, that the listing, registration or qualification of the Shares upon any securities exchange or under any state or
federal law, or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of shares to Participant (or his estate), such issuance will not occur unless and until such listing,
registration, qualification, consent or approval will have been effected or obtained free of any conditions not acceptable to the Company. Where the Company determines that the delivery of the payment of any Shares will violate federal
securities laws or other applicable laws, the Company will defer delivery until the earliest date at which the Company reasonably anticipates that the delivery of Shares will no longer cause such violation. The Company will make all
reasonable efforts to meet the requirements of any such state or federal law or securities exchange and to obtain any such consent or approval of any such governmental authority. The Company represents and acknowledges that, as of the
Date of Grant, there are currently no delivery restrictions in effect of the type referred to in this Section 13.

14.

Plan Governs. This Agreement is subject to all terms and provisions of the Plan. In the event of a conflict between one or more provisions of this Agreement and one or more provisions of the Plan, the provisions of the

Plan will govern.

15.

Administrator Authority. The  Administrator  will  have  the  power  to  interpret  the  Plan  and  this  Agreement  and  to  adopt  such  rules  for  the  administration,  interpretation  and  application  of  the  Plan  as  are  consistent
therewith and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any Restricted Stock Units have vested). All actions taken and all interpretations and determinations made by the
Administrator in good faith will be final and binding upon Participant, the Company and all other interested persons. No member of the Administrator will be personally liable for any action, determination or interpretation made in good
faith with respect to the Plan or this Agreement.

16.

Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related to Restricted Stock Units awarded under the Plan or future Restricted Stock Units that may be awarded under the
Plan by electronic means or request Participant’s consent to participate in the Plan by electronic means. Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or
electronic system established and maintained by the Company or another third party designated by the Company.

17.

18.

Captions. Captions provided herein are for convenience only and are not to serve as a basis for interpretation or construction of this Agreement.

Agreement Severable. In the event that any provision in this Agreement will be held invalid or unenforceable, such provision will be severable from, and such invalidity or unenforceability will not be construed to have

any effect on, the remaining provisions of this Agreement.

19.

Section 409A. Notwithstanding anything in the Plan or this Agreement to the contrary, if the vesting of the balance, or some lesser portion of the balance, of the Restricted Stock Units is accelerated in connection with
Participant’s  termination  as  a  Service  Provider  (provided  that  such  termination  is  a  “separation  from  service”  within  the  meaning  of  Section  409A,  as  determined  by  the  Company),  other  than  due  to  death,  and  if  (x)  Participant  is  a
“specified  employee”  within  the  meaning  of  Section  409A  at  the  time  of  such  termination  as  a  Service  Provider  and  (y)  the  payment  of  such  accelerated  Restricted  Stock  Units  would  result  in  the  imposition  of  additional  tax  under
Section 409A if paid to Participant on or within the six (6) month period following Participant’s termination as a Service Provider, then the payment of such accelerated Restricted Stock Units will not be made until the date six (6) months
and one (1) day following the date of Participant’s termination as a Service Provider, unless the Participant dies following his or her termination as a Service Provider, in which case, the Restricted Stock Units will be paid in Shares to the
Participant’s estate as soon as practicable following his or her death. It is the intent of this Agreement to comply with the requirements of Section 409A so that none of the Restricted Stock Units provided under this Agreement or Shares
issuable thereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to so comply. For purposes of this Agreement, “Section 409A” means Section 409A of the Code, and any
proposed, temporary or final Treasury Regulations and Internal Revenue Service guidance thereunder, as each may be amended from time to time.

20.

Governing Law. This Award Agreement shall be governed by the laws of the State of California, without giving effect to the conflict of law principles thereof. For purposes of litigating any dispute that arises under this
Award of Restricted Stock Units or this Agreement, the parties hereby submit to and consent to the jurisdiction of the State of California, and agree that such litigation shall be conducted in the courts of Santa Clara County, California, or
the federal courts for the United States for the Northern District of California, and no other courts, where this Award of Restricted Stock Units is made and/or to be performed.

terms  and  provisions  thereof.  Participant  has  reviewed  the  Plan  and  this  Agreement  in  their  entirety,  has  had  an  opportunity  to  obtain  the  advice  of  counsel  prior  to  executing  this  Agreement  and  fully  understands  all

and/or the Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Restricted Stock Unit, including, but not
limited to, the grant, vesting or settlement of the Restricted Stock Units, the subsequent sale of Shares acquired pursuant to such settlement, and the receipt of any dividends or dividend equivalents;
and (2) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Restricted Stock Unit to reduce or eliminate Participant’s liability for Tax-Related Items or
achieve any particular tax result. Further, if Participant is subject to Tax-Related Items in more than one jurisdiction, Participant acknowledges that the Company and/or the Employer (or former
employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Prior to any relevant taxable or tax withholding event, as applicable, Participant agrees to make adequate arrangements satisfactory to the Company and/or the Employer to satisfy any applicable
withholding obligations  for  Tax-Related  Items. In  this  regard,  Participant  authorizes  the  Company  and/or  the  Employer,  or  their  respective  agents,  at  their  discretion,  to  satisfy  their  withholding
obligations with regard to all Tax-Related Items by one or a combination of the following:

(a)

withholding from Participant’s wages or other cash compensation paid to Participant by the Company and/or the Employer; or

arranged by the Company (on Participant’s behalf pursuant to this authorization without further consent); or

(b)

withholding  from  proceeds  of  the  sale  of  Shares  acquired  upon  settlement  of  the  Restricted  Stock  Units  either  through  a  voluntary  sale  or  through  a  mandatory  sale

(c)

withholding in Shares to be issued upon settlement of the Restricted Stock Units.

Notwithstanding the above, in the event that Participant is a Section 16 officer of the Company under the Exchange Act, then the Company will withhold Shares to be issued upon vesting of the
Restricted Stock Units, unless otherwise determined by the Administrator, or in the event that withholding in Shares is problematic under applicable tax or securities law or has materially adverse tax
consequences.

Depending on the withholding method, the Company may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding rates or other applicable withholding
rates, including maximum applicable rates, in which case Participant may receive a refund of any over-withheld amount in cash and will have no entitlement to the Share equivalent. If the obligation
for  Tax-Related  Items  is  satisfied  by  withholding  in  Shares,  for  tax  purposes,  Participant  is  deemed  to  have  been  issued  the  full  number  of  Shares  subject  to  the  vested  Restricted  Stock  Units,
notwithstanding that a number of the Shares are held back solely for the purpose of paying the Tax-Related Items.

Finally, Participant agrees to pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of
Participant’s participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to issue or deliver the Shares or the proceeds of the sale of Shares, if
Participant fails to comply with Participant’s obligations in connection with the Tax-Related Items. If Participant does not accept the terms of this Agreement including this Section 7, then at the time
any  applicable  Restricted  Stock  Units  otherwise  are  scheduled  to  vest  pursuant  to  Section  3,  Participant  will  permanently  forfeit  such  Restricted  Stock  Units  to  the  Company  at  no  cost  to  the
Company and Participant will have no rights whatsoever to receive any Shares hereunder.

8.    Rights as Stockholder. Neither Participant nor any person claiming under or through Participant will have any of the rights or privileges of a stockholder of the Company in respect of any
Shares deliverable hereunder, unless and until certificates or other evidence of ownership representing such Shares will have been issued, recorded on the records of the Company or its transfer agents
or registrars, and delivered to Participant.

9.    Section 409A. Notwithstanding anything in the Plan or this Agreement to the contrary, if the vesting of the balance, or some lesser portion of the balance, of the Restricted Stock Units is
accelerated in connection with Participant’s termination as a Service Provider (provided that such termination is a “separation from service” within the meaning of Section 409A, as determined by the
Company), other than due to death, and if (a) Participant is a “specified employee” within the meaning of Section 409A at the time of such termination as a Service Provider and (b) the payment of
such  accelerated  Restricted  Stock  Units  will  result  in  the  imposition  of  additional  tax  under  Section  409A  if  paid  to  Participant  on  or  within  the  six  (6)  month  period  following  Participant’s
termination as a Service Provider, then the payment of such accelerated Restricted Stock Units will not be made until the date six (6) months and one (1) day following the date of Participant’s
termination as a Service Provider, unless the Participant dies following his or her termination as a Service Provider, in which case, the Restricted Stock Units will be paid in Shares to the Participant’s
estate as soon as practicable following his or her death. It is the intent of this Agreement that it and all payments and benefits hereunder be exempt from, or comply with, the requirements of Section
409A so that none of the Restricted Stock Units provided under this Agreement or Shares issuable thereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities
herein  will  be  interpreted  to  be  so  exempt  or  so  comply.  Each  payment  payable  under  this  Agreement  is  intended  to  constitute  a  separate  payment  for  purposes  of  Treasury  Regulation  Section
1.409A-2(b)(2). For purposes of this Agreement, “Section 409A” means Section 409A of the Code, and any final Treasury Regulations and Internal Revenue Service guidance thereunder, as each
may be amended from time to time.

10.    Nature of Grant. In accepting the grant, Participant acknowledges, understands and agrees that:

(a)
to the extent permitted by the Plan;

the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the Company at any time,

(c)

all decisions with respect to future Restricted Stock Unit or other grants, if any, will be at the sole discretion of the Company;

the Restricted Stock Unit grant and Participant’s participation in the Plan shall not create a right to employment or service, or be interpreted as forming or amending an

employment or status as a Service Provider (if any);

no claim or entitlement to compensation or damages shall arise from forfeiture of the Restricted Stock Units resulting from Participant’s ceasing to provide employment
or  other  services  to  the  Company  or  the  Employer  (for  any  reason  whatsoever,  whether  or  not  later  found  to  be  invalid  or  in  breach  of  employment  laws  in  the  jurisdiction  where  Participant  is
employed  or  the  terms  of  Participant’s  employment  agreement,  if  any)  and  in  consideration  of  the  grant  of  the  Restricted  Stock  Units,  Participant  agrees  not  to  institute  any  claim  against  the
Company, any of its Affiliates, or the Employer;

(k)

for purposes of this Agreement, Participant’s relationship as a Service Provider will be considered terminated as of the date Participant is no longer actively providing
services to the Company or one of its Affiliates or the Employer (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the
jurisdiction where Participant is employed or the terms of Participant’s employment agreement, if any), and unless otherwise expressly provided in this Agreement or determined by the Company,
Participant’s right to vest in the Restricted Stock Units under the Plan, if any, will terminate effective as of such date and will not be extended by any notice period (e.g., active services would not
include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where Participant is employed or the terms of Participant’s
employment agreement, if any); the Administrator shall have the exclusive discretion to determine when Participant is no longer actively providing services for purposes of the Restricted Stock Unit
grant (including whether Participant may still be considered to be providing services while on an approved leave of absence);

(l)

unless otherwise provided in the Plan or by the Company in its discretion, the Restricted Stock Units and the benefits evidenced by this Agreement do not create any
entitlement to have the Restricted Stock Units or any such benefits transferred to, or assumed by, another company nor to be exchanged, cashed out or substituted for, in connection with any corporate
transaction affecting the Shares; and

(m)

neither the Company, the Employer nor any Affiliate shall be liable for any foreign exchange rate fluctuation between Participant’s local currency and the United States

Dollar that may affect the value of the Restricted Stock Units or the subsequent sale of any Shares acquired upon settlement.

11.    No Advice Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding Participant’s participation in
the Plan, or Participant’s acquisition or sale of the underlying Shares. Participant understands and agrees that he or she should consult with his or her own personal tax, legal and financial advisors
regarding his or her participation in the Plan before taking any action related to the Plan.

12.    Data Privacy.

(a)

Data Collection and Usage. The Company and the Employer will collect, process and use certain personal information about Participant, specifically, Participant’s
name, home address, email address and telephone number, date of birth, social security or insurance number, passport number or other identification number, salary, nationality, job title, any
Shares  or  directorships  held  in  the  Company,  details  of  all  Restricted  Stock  Units  or  any  other  entitlement  to  Shares  awarded,  canceled,  exercised,  vested,  unvested  or  outstanding  in
Participant’s  favor  (“Data”),  for  the  exclusive  purpose  of  implementing,  administering  and  managing  the  Plan.  The  legal  basis,  where  required,  for  the  processing  of  Data  is  Participant’s
consent.  In  addition  to  the  above-identified  recipients  and  where  required  under  applicable  law,  Data  also  may  be  disclosed  to  certain  securities  or  other  regulatory  authorities  where  the
Company’s securities are listed or traded or regulatory filings are made. The legal basis, where required, for such disclosure is compliance with applicable law.

(b)

Stock Plan Administration Service Providers.  The  Company  and  the  Employer  transfer  Data  to  ETRADE,  the  designated  broker  assisting  in  the  implementation,
administration and management of the Plan. Upon transfer of Participant’s Data to ETRADE, Participant may be asked to agree to separate terms and data processing practices with ETRADE
with such agreement being a condition of the ability to participate in the Plan.

(c)

Other  Service  Provider  Data  Recipients.  The  Company  also  may  transfer  Data  to  other  third  party  service  providers,  if  necessary  to  ensure  compliance  with
applicable  tax,  exchange  control,  securities  and  labor  law.  Such  third  party  service  providers  may  include  the  Company’s  legal  counsel  as  well  as  its  auditor/accountant/third  party  vendor
(currently PwC). Wherever possible, the Company will anonymize data, but Participant understands that his or her Data may need to be transferred to such providers to ensure compliance with
applicable law and/or tax requirements.

(d)

International Data Transfers. The Company, ETRADE and its other service providers described above under (c) are located in the United States. The United States
may have different data privacy laws and protections than Participant’s country of residence (or country of employment, if different). The Company’s legal basis, where required, for the transfer
of Data is Participant’s consent.

When the Company no longer needs the Data, the Company will remove it from its systems.

(e)

Data Retention. Participant understands that Data will be held only as long as is necessary to implement, administer and manage his or her participation in the Plan.

(f)

Data Subject Rights. Participant understands that Participant may have the right under applicable law to (i) access or copy Data that the Company possesses, (ii)
rectify  incorrect  Data,  (iii)  delete  Data,  (iv)  restrict  processing  of  Data,  (vi)  lodge  complaints  with  the  competent  supervisory  authorities  in  Participant’s  jurisdiction.  To  receive  clarification
regarding these rights or to exercise these rights, Participant understands that Participant can contact his or her local human resources representative.

(g)

Voluntariness and Consequences of Consent, Denial or Withdrawal. Participation in the Plan is voluntary and Participant understands that Participant is providing
the  consent  herein  on  a  purely  voluntary  basis.  If  Participant  does  not  consent,  or  later  seeks  to  revoke  his  or  her  consent,  Participant’s  employment  status  or  service  and  career  with  the
Employer will not be adversely affected. The only consequence of refusing or withdrawing consent is that the Company would not be able to grant Restricted Stock Units or other equity awards
to Participant or administer or maintain such awards. Therefore, Participant understands that refusing or withdrawing his or her consent may affect Participant’s ability to participate in the
Plan. For more information on the consequences of Participant’s refusal to consent or withdrawal of consent, Participant understands that Participant may contact his or her human resources
representative.

(h)

Declaration of Consent. Participant hereby explicitly and unambiguously consents to the collection, processing and use, in electronic or other form, of Participant’s
Data by the Company and the transfer of Data to the recipients mentioned above, including recipients located in countries which do not adduce an adequate level of protection from a European
(or other non-U.S.) data protection law perspective, for the purposes described above.

13.        Address  for  Notices.  Any  notice  to  be  given  to  the  Company  under  the  terms  of  this  Agreement  will  be  addressed  to  the  Company,  in  care  of  Stock  Administrator  at  Align

hypothecated in any way (whether by operation of law or otherwise) and will not be subject to sale under execution, attachment or similar process. Upon  any  attempt  to  transfer,  assign,  pledge,

legal representatives, successors and assigns of the parties hereto.

registration, qualification or other legal requirement applicable to the Shares, the Company shall not be required to deliver any Shares issuable upon settlement of the Restricted Stock Units prior to
the completion of any registration or qualification of the Shares under any local, state, federal or foreign securities or exchange control law or under rulings or regulations of the U.S. Securities and
Exchange Commission (“SEC”) or of any other governmental regulatory body, or prior to obtaining any approval or other clearance from any local, state, federal or foreign governmental agency,
which registration, qualification or approval the Company shall, in its absolute discretion deem necessary or advisable. Participant understands that the Company is under no obligation to register or
qualify the Shares with the SEC or any state or foreign securities commission or to seek approval or clearance from any governmental authority for the issuance or sale of Shares. Further, Participant
agrees  that  the  Company  shall  have  the  unilateral  authority  to  amend  the  Plan  and  this  Agreement  without  Participant’s  consent  to  the  extent  necessary  to  comply  with  securities  or  other  laws
applicable to the issuance of Shares.

taken and all interpretations and determinations made by the Administrator in good faith will be final and binding upon Participant, the Company and all other interested persons. No member of the
Administrator will be personally liable for any action, determination or interpretation made in good faith with respect to the Plan or this Agreement.

19.    Electronic Delivery and Acceptance. The Company may, in its sole discretion, decide to deliver any documents related to current or future participation in the Plan by electronic means.
Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company

22.    Governing Law and Venue. The grant of the Restricted Stock Units and this Agreement shall be governed by the laws of the State of California, without giving effect to the conflict of
law principles thereof. For purposes of any action, lawsuit or other proceedings brought to enforce this Agreement, relating to it, or arising from it, the parties hereby submit to and consent to the sole

this Agreement or any other document related to the Plan translated into a language other than English and if the meaning of the translated version is different than the English version, the English
version will control.

24.    Appendix. Notwithstanding any provisions in this Agreement, the Restricted Stock Unit grant shall be subject to any special terms and conditions set forth in any Appendix to this
Agreement for Participant’s country. Moreover, if Participant relocates to one of the countries included in the Appendix, the special terms and conditions for such country will apply to Participant, to
the extent the Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative reasons. The Appendix constitutes part of this Agreement.

25.    Imposition of Other Requirements. The Company reserves the right to impose other requirements on Participant’s participation in the Plan, on the Restricted Stock Units and on any
Shares acquired under the Plan, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to require Participant to sign any additional agreements or
undertakings that may be necessary to accomplish the foregoing.

26.    Insider Trading/Market Abuse Laws. Participant acknowledges that, depending on Participant’s country of residence, the broker’s country, or the country in which the Shares are listed,
he or she may be subject to insider trading and/or market abuse laws in applicable jurisdictions, which may affect Participant's ability to, directly or indirectly, accept, acquire, sell or attempt to sell or
otherwise dispose of Shares, or rights to Shares (e.g., Restricted Stock Units), or rights linked to the value of Shares, during such times as Participant is considered to have “inside information”
regarding  the  Company  (as  defined  by  the  laws  or  regulations  in  the  applicable  jurisdiction  or  Participant's  country).    Local  insider  trading  laws  and  regulations  may  prohibit  the  cancellation  or
amendment of orders Participant placed before possessing the inside information. Furthermore, Participant may be prohibited from (i) disclosing the inside information to any third party, including
fellow  employees  (other  than  on  a  “need  to  know”  basis)  and  (ii)  “tipping”  third  parties  or  causing  them  to  otherwise  buy  or  sell  securities.  Any  restrictions  under  these  laws  or  regulations  are
separate from and in addition to any restrictions that may be imposed under any applicable Company insider trading policy. Participant acknowledges that it is his or her responsibility to be informed
of and compliant with any such laws, and Participant should speak to his or her personal advisor on this matter.

27.    Exchange Control Tax and Foreign Asset/Account Reporting Requirements. Participant acknowledges that there may be exchange control, tax, foreign asset and/or account reporting
requirements which may affect Participant’s ability to acquire or hold Shares acquired under the Plan or cash received from participating in the Plan (including from any dividends paid on Shares
acquired under the Plan) in a brokerage, bank account or legal entity outside Participant’s country. Participant may be required to report such accounts, balances, assets and/or the related transactions

country through a designated bank or broker within a certain time after receipt. Participant acknowledges that it is Participant’s responsibility to be compliant with such regulations, and Participant
should consult his or her personal legal advisor for any details.    

28.    Waiver. Participant acknowledges that a waiver by the Company of breach of any provision of this Agreement shall not operate or be construed as a waiver of any other provision of this

Agreement, or of any subsequent breach by Participant or any other Participant.

terms not explicitly defined in this Appendix have the definitions ascribed to them in the Align Technology, Inc. 2005 Incentive Plan (the “Plan”) and/or the Agreement.

This  Appendix  also  includes  information  regarding  exchange  controls  and  certain  other  issues  of  which  Participant  should  be  aware  with  respect  to  Participant’s  participation  in  the  Plan.  The
information is based on the securities, exchange control and other laws in effect in the respective countries as of January 2019. Such laws are often complex and change frequently. As a result, the
Company  strongly  recommends  that  Participant  not  rely  on  the  information  noted  herein  as  the  only  source  of  information  relating  to  the  consequences  of  Participant’s  participation  in  the  Plan
because the information may be out of date at vesting of the Restricted Stock Units or the subsequent sale of the Shares or the receipt of any dividends or dividend equivalents.

In addition, the information is general in nature and may not apply to Participant’s particular situation, and the Company is not in a position to assure Participant of any particular result. Accordingly,
Participant is advised to seek appropriate professional advice as to how the relevant laws in Participant’s country may apply to Participant’s situation.

Finally, if Participant is a citizen or resident of a country other than the one in which Participant is currently working, transfers employment to another country after the Restricted Stock Units are

Foreign  Asset/Account  Reporting  Information.  Canadian  taxpayers  are  required  to  report  any  foreign  assets  (including  Shares  acquired  under  the  Plan  and,  likely,  unvested  RSUs)  with  a  cost
exceeding CAD 100,000 on Form T1135 (Foreign Income Verification Statement) on an annual basis. For Shares acquired under the Plan, cost generally is the adjusted cost basis (“ACB”), which
would ordinarily be equal the fair market value of the Shares at the time of acquisition. If, however, a Canadian taxpayer owns other shares in the Company, the ACB of the Shares acquired under the
Plan will need to be leveraged with the ACB of the other Shares. The statement is due at the same time as the taxpayer’s annual tax return. Taxpayers are advised to check with their personal advisor
regarding the reporting obligations.

CHINA

Terms and Conditions

The following terms and conditions will apply to Participants who are subject to exchange control restrictions and regulations in the People’s Republic of China (the “PRC”), including requirements
imposed by the State Administration of Foreign Exchange (“SAFE”), as determined by the Company in its sole discretion.

Termination of Service Relationship. Due to exchange control laws in the PRC, Participant agrees that the Company reserves the right to require the sale of any Shares acquired at vesting of the
Restricted Stock Units upon the termination of Participant’s relationship as a Service Provider for any reason. If the Company, in its discretion, does not exercise its right to require the automatic sale
of Shares issuable upon vesting of the Restricted Stock Units, as described in the preceding sentence, Participant understands and agrees that any Shares acquired by Participant under the Plan must
be sold no later than three (3) months after termination of Participant’s relationship as a Service Provider, or within any other such time frame as permitted by the Company or required for legal or
administrative  reasons.  Participant  understands  that  any  Shares  acquired  under  the  Plan  that  have  not  been  sold  within  three  (3)  months  of  termination  of  Participant’s  relationship  as  a  Service
Provider will be automatically sold by a designated broker at the Company’s discretion, pursuant to this authorization by Participant.

Participant  agrees  that  the  Company  is  authorized  to  instruct  its  designated  broker  to  assist  with  the  mandatory  sale  of  such  Shares  (on  Participant’s  behalf,  pursuant  to  this  authorization)  and
Participant expressly authorizes the Company’s designated broker to complete the sale of such Shares. Participant also agrees to sign any agreements, forms, and/or consents that may be reasonably
requested by the Company (or the designated broker) to effectuate the sale of the Shares (including, without limitation, as to the transfers of the proceeds and other exchange control matters noted
below) and shall otherwise cooperate with the Company with respect to such matters, provided that Participant shall not be permitted to exercise any influence over how, when or whether the sales
occur. Participant acknowledges that the Company’s designated broker is under no obligation to arrange for the sale of the Shares at any particular price. Due to fluctuations in the Share price and/or
applicable exchange rates between vesting and (if later) the date on which the Shares are sold, the amount of proceeds ultimately distributed to Participant may be more or less than the market value
of the Shares upon vesting (which is the amount relevant to determining Participant’s liability for Tax-Related Items). Participant understands and agrees that the Company is not responsible for the
amount of any loss Participant may incur and the Company assumes no liability for any fluctuations in the Share price and/or any applicable exchange rate.

Upon the sale of the Shares, the Company agrees to pay the cash proceeds from the sale (less any Tax-Related Items, brokerage fees and commissions) to Participant in accordance with the applicable
exchange control laws and regulations including but not limited to the restrictions set forth in this Appendix for China below under “Exchange Control Restrictions.”

Exchange Control Restrictions. Participant understands and agrees that, pursuant to local exchange control requirements, Participant will be required to immediately repatriate any cash payments or
proceeds obtained with respect to participation in the Plan to the PRC. Participant further understands that such repatriation of any cash payments or proceeds may need to be effectuated through a
special exchange control account established by the Company or any Affiliate, and Participant hereby consents and agrees that any payment or proceeds may be transferred to such special account
prior to being delivered to Participant. Any payment or proceeds may be paid to Participant in U.S. dollars or local currency at the Company’s discretion. If the payments or proceeds are paid to
Participant in U.S. dollars, Participant will be required to set up a U.S. dollar bank account in the PRC (if Participant does not already have one) so that the payments or proceeds may be deposited
into this account. If the payments or proceeds are paid to Participant in local currency, the Company is under no obligation to secure any particular currency exchange rate and the Company may face
delays in converting the payments or proceeds to local currency due to exchange control restrictions. Participant agrees to bear any currency exchange rate fluctuation risk between the time the cash
proceeds are received and the time the cash proceeds are distributed to Participant through the special account described above. Participant further agrees to comply with any other requirements that
may be imposed by the Company in the future to facilitate compliance with exchange control requirements in the PRC

NEW ZEALAND

Notifications

Securities Law Notification. Warning: This is an offer of rights to receive Shares underlying the Restricted Stock Units. Restricted Stock Units give Participant a potential stake in the ownership of
the Company. Participant may receive a return if dividends are paid on the Shares issued pursuant to the vesting of the Restricted Stock Units.

If the Company runs into financial difficulties and is wound up, Participant will be paid only after all creditors and holders of preferred shares have been paid. Participant may lose some or all of his
or her investment.

New  Zealand  law  normally  requires  people  who  offer  financial  products  to  give  information  to  investors  before  they  invest.  This  information  is  designed  to  help  investors  to  make  an  informed
decision. The usual rules do not apply to this offer because it is made under an employee share scheme. As a result, Participant may not be given all the information usually required. Participant will
also have fewer legal protections for this investment.

Participant should ask questions, read all documents carefully, and seek independent financial advice before committing himself or herself.

In addition, Participant is hereby notified that the documents listed below are available for review on the Company’s “Investors” website at http://investor.aligntech.com/:

(i)    a copy of the Company’s most recent annual report (i.e., Form 10-K);

RUSSIA

Terms and Conditions

U.S. Transaction. Acceptance of the grant of the Restricted Stock Units results in a contract between Participant and the Company completed in the United States and the Agreement is governed by
the laws of the State of California, without giving effect to the conflict of law principles thereof. Upon vesting of the Restricted Stock Units, any Shares to be issued to Participant shall be delivered to
Participant through a brokerage account in the United States and in no event will such Shares be delivered to Participant in Russia. Participant acknowledges that he or she is not permitted to sell or
otherwise transfer Shares directly to other individuals in Russia, nor is Participant permitted to bring any certificates representing the Shares into Russia (if such certificates are issued). Participant is
permitted to sell Shares only on the Nasdaq stock exchange, on which the Shares are listed, and only through a U.S. broker.

Settlement of Restricted Stock Units and Sale of Shares. Depending on the development of local regulatory requirements, the Company reserves the right to force the immediate sale of any Shares to

of  such  Shares  (on  Participant’s  behalf  pursuant  to  this  authorization)  and  Participant  expressly  authorizes  the  Company’s  designated  broker  to  complete  the  sale  of  such  Shares.  Participant

participate in the Plan.

and funds remitted into Russia in connection with the Plan. This may include, in certain circumstances, reporting and repatriation requirements. Participant should contact his or her personal advisor
regarding any such requirements resulting from participation in the Plan.

Securities Law Information. The grant of the Restricted Stock Units and the distribution of the Plan and all other materials Participant may receive regarding participation in the Plan do not constitute
an offering or the advertising of securities in Russia. The issuance of Shares pursuant to the Plan has not and will not be registered in Russia and, therefore, the Shares may not be used for an offering
or public circulation in Russia. In no event will Shares be delivered to Participant in Russia; all Shares acquired under the Plan will be maintained on Participant’s behalf in the United States.

Foreign Asset/Account Reporting Notification. Russian residents are also required to file reports of transactions in their foreign bank accounts on an annual basis with the Russian tax authorities. The
tax  authorities  can  require  any  supporting  documents  related  to  the  transaction  in  a  Russian  resident's  foreign  bank  account.  Participant  should  consult  with  his  or  her  personal  tax  advisor  for

SPAIN

Terms and Conditions

No Entitlement for Claims or Compensation. The following provision supplements Section 10 of the Agreement:

By accepting the Restricted Stock Units, Participant consents to participation in the Plan and acknowledges that the he or she has received a copy of the Plan document.

Participant understands that the Company has unilaterally, gratuitously and in its sole discretion decided to grant Restricted Stock Units under the Plan to individuals who may be Service Providers
throughout the world. The decision is limited and entered into based upon the express assumption and condition that any Restricted Stock Units will not economically or otherwise bind the Company
or any Parent or Affiliate, including the Employer, on an ongoing basis, other than as expressly set forth in the Agreement. Consequently, Participant understands that the Restricted Stock Units are
granted on the assumption and condition that the Restricted Stock Units shall not become part of any employment or service contract (whether with the Company or any Parent or Affiliate, including
the Employer) and shall not be considered a mandatory benefit, salary for any purpose (including severance compensation) or any other right whatsoever. Furthermore, Participant understands and
freely accepts that there is no guarantee that any benefit whatsoever shall arise from the grant of Restricted Stock Units, which are gratuitous and discretionary, since the future value of the Restricted
Stock Units and the underlying Shares is unknown and unpredictable.

In  addition,  Participant  understands  that  this  grant  of  Restricted  Stock  Units  would  not  be  made  but  for  the  assumptions  and  conditions  set  forth  hereinabove;  thus,  Participant  understands,
acknowledges and freely accepts that, should any or all of the assumptions be mistaken or any of the conditions not be met for any reason, the Restricted Stock Units and any right to the underlying
Shares shall be null and void.

Further, the vesting of the Restricted Stock Units is expressly conditioned on Participant’s continued and active rendering of service, such that if Participant’s status as a Service Provider is terminated
for any reason whatsoever, the Restricted Stock Units may cease vesting immediately, in whole or in part, effective on the date of Participant’s termination as a Service Provider. This will be the case,
for example, even if (1) Participant is considered to be unfairly dismissed without good cause; (2) Participant is dismissed for disciplinary or objective reasons or due to a collective dismissal; (3)
Participant terminates his or her relationship as a Service Provider due to a change of work location, duties or any other employment or contractual condition; (4) Participant terminates his or her
relationship as a Service Provider due to a unilateral breach of contract by the Company or an Affiliate; or (5) Participant’s status as a Service Provider is terminated for any other reason whatsoever.
Consequently, upon termination of Participant’s status as a Service Provider for any of the above reasons, Participant may automatically lose any rights to Restricted Stock Units that were not vested
on the date of Participant’s termination as a Service Provider, as described in the Plan and the Agreement.

(a)

(b)

The Company hereby grants to Participant under the Plan an Award of Market Stock Units, subject to all of the terms and conditions in the Notice of Grant, this Agreement and the Plan.

The number of Market Stock Units in which the Participant may vest in accordance with the Vesting Schedule set forth in the Notice of Grant will depend upon the Company’s Stock Price

Performance as compared to the NASDAQ Composite Index Performance calculated on February 15, 2022 (the “Measurement Date”) with 100% of the Market Stock Units eligible to vest on the Vesting Date. The actual number of Market
Stock Units that will vest on the Vesting Date will be determined as follows:

period ending on February 15 of the year of grant over (ii) the per share value of the Company’s common stock paid to its stockholders in connection with the Change of Control.

Stock Units, multiplied by (ii) the sum of (A) 100% plus (B) three times the Growth Rate Delta; provided, however, that in no event will more than the Maximum Number of Market Stock Units become Calculated Market Stock Units on
the Vesting Date. If the Growth Rate Delta is equal to negative-33.3%, then the number of Target Market Stock Units that will become Calculated Market Stock Units on the Vesting Date will equal 0.

If the Growth Rate Delta on the Measurement Date equaled 20%, then 160% (equal to 100% plus (3 times 20%)) of the Target Number of Market Stock Units would be Calculated Market Stock
Units and would vest on the Vesting Date.

If the Growth Rate Delta on the Measurement Date equaled negative-20%, then 40% (equal to 100% plus (3 times negative-20%)) of the Target Number of Market Stock Units would be Calculated
Market Stock Units and would vest on the Vesting Date.

2.

Company’s Obligation to Pay.  Each Market Stock Unit represents a value equal to the Fair Market Value of a Share on the date it is granted.  Unless and until the Market Stock Units will have vested in the manner set

forth in Sections 3, 4 and 5, Participant will have no right to payment of any such Market Stock Units.  Prior to actual payment of any vested Market Stock Units, such Market Stock Unit will represent an unsecured obligation of the
Company, payable (if at all) only from the general assets of the Company. Payment of any vested Market Stock Units will be made in whole Shares only and any fractional Shares will be forfeited at the time of payment.

3.

Vesting Schedule.  Subject to Section 5, the Market Stock Units awarded by this Agreement will vest in Participant according to the Vesting Schedule set forth on the attached Notice of Grant, subject to Participant

and the NASDAQ Composite Index Performance and the number of Market Stock Units that are Calculated Market Stock Units will be determined in accordance with the Performance Matrix and Section 1 of this Exhibit A. The
Participant shall vest in the number of Calculated Market Stock Units determined based on the preceding sentence as follows:

(a)    if Participant’s employment is terminated without Cause or for Good Reason (as such terms are defined in Participant’s individual employment agreement with the Company) within eighteen months following the

occurrence of a Change of Control, then 100% of his or her unvested Calculated Market Stock Units will fully vest, provided the Participant executes and does not revoke a release of claims as provided for in Participant’s employment
agreement (as a necessary condition to the receipt of severance thereunder).

(b)    in accordance with Section 1 of this Exhibit A, the Administrator shall not be entitled to eliminate or reduce the number of Calculated Market Stock Units determined in accordance with Section 1of Exhibit A

following a Change of Control.

5.

Forfeiture upon Termination of Status as a Service Provider.  Subject to the provisions of Section 4, if Participant ceases to be a Service Provider for any or no reason, the then-unvested Market Stock Units awarded by

this Agreement will thereupon be forfeited at no cost to the Company and Participant will have no further rights thereunder.

6.

Payment after Vesting.  Any Market Stock Units that vest in accordance with Sections 3 and 4 will be paid to Participant (or in the event of Participant’s death, to his or her estate) in whole Shares, subject to Participant
satisfying any applicable tax withholding obligations as set forth in Section 8. Subject to the provisions of Section 20, any Shares will be issued to Participant as soon as practicable after the relevant vesting date, but in any event, within the
period ending on the later to occur of the date that is two-and-one-half months from the end of (a) Participant’s tax year that includes the vesting date, or (b) the Company’s tax year that includes the vesting date.

Participant, the administrator or executor of Participant’s estate.  Any such transferee must furnish the Company with (a) written notice of his or her status as transferee, and (b) evidence satisfactory to the Company to establish the validity

 
        
 
 
    
 
 
 
 
 
 
 
 
of the transfer and compliance with any laws or regulations pertaining to said transfer.

8.

Withholding of Taxes. 

(a) Generally. The Participant is ultimately liable and responsible for all taxes owed in connection with the Market Stock Units, regardless of any action the Company or any of its Subsidiaries takes with respect to any

tax withholding obligations that arise in connection with the Market Stock Units. Neither the Company nor any of its Subsidiaries makes any representation or undertaking regarding the treatment of any tax

withholding in connection with the grant or vesting of the Market Stock Units or the subsequent sale of Shares issuable pursuant to the Market Stock Units. The Company and its Subsidiaries do not commit and are

under no obligation to structure the Market Stock Units to reduce or eliminate the Participant’s tax liability.

(b) Payment of Withholding Taxes. Notwithstanding any contrary provision of this Agreement, no Shares will be issued to Participant, unless and until satisfactory arrangements (as determined by the Administrator) will
have been made by the Participant with respect to the payment of any taxes which the Company determines must be withheld with respect to the Market Stock Units. The Administrator, in its sole discretion and

pursuant to such procedures as it may specify from time to time, may satisfy such tax withholding obligations, in whole or in part, by withholding otherwise deliverable Shares having an aggregate Fair Market Value

sufficient to (but not exceeding) the minimum amount required to be withheld. In addition and to the maximum extent permitted by law, the Company has the right to retain without notice from salary or other

amounts payable to the Participant, cash having a value sufficient to satisfy any tax withholding obligations that cannot be satisfied by the withholding of otherwise deliverable Shares.

9.

Rights as Stockholder.  Neither Participant nor any person claiming under or through Participant will have any of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder,

unless and until certificates representing such Shares will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to Participant.

10.

No Effect on Service.  Participant acknowledges and agrees that the vesting of the Market Stock Units pursuant to Sections 3 or 4 hereof is earned only by Participant continuing to be a Service Provider through the
applicable vesting dates (and not through the act of being hired or acquiring Shares hereunder).  Participant further acknowledges and agrees that this Agreement, the transactions contemplated hereunder and the vesting schedule set forth
herein do not constitute an express or implied promise of Participant continuing to be a Service Provider for the vesting period, for any period, or at all, and will not interfere with the Participant’s right or the right of the Company (or the
Affiliate employing or retaining Participant) to terminate Participant as a Service Provider at any time, with or without cause.

11.

Address for Notices.  Any notice to be given to the Company under the terms of this Agreement will be addressed to the Company, in care of Stock Administrator at Align Technology, Inc., 2560 Orchard Parkway,

San Jose, CA 95131, or at such other address as the Company may hereafter designate in writing.

12.

Grant is Not Transferable.  Except to the limited extent provided in Section 7, this grant and the rights and privileges conferred hereby will not be transferred, assigned, pledged or hypothecated in any way (whether by

operation of law or otherwise) and will not be subject to sale under execution, attachment or similar process.  Upon any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of this grant, or any right or privilege conferred
hereby, or upon any attempted sale under any execution, attachment or similar process, this grant and the rights and privileges conferred hereby immediately will become null and void.

13.

Binding Agreement.  Subject to the limitation on the transferability of this grant contained herein, this Agreement will be binding upon and inure to the benefit of the heirs, legatees, legal representatives, successors

and assigns of the parties hereto.

14.

Additional Conditions to Issuance of Stock.  If at any time the Company will determine, in its discretion, that the listing, registration or qualification of the Shares upon any securities exchange or under any state or

federal law, or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of shares to Participant (or his estate), such issuance will not occur unless and until such listing,
registration, qualification, consent or approval will have been effected or obtained free of any conditions not acceptable to the Company.  Where the Company determines that the delivery of the payment of any Shares will violate federal
securities laws or other applicable laws, the Company will defer delivery until the earliest date at which the Company reasonably anticipates that the delivery of Shares will no longer cause such violation.  The Company will make all
reasonable efforts to meet the requirements of any such state or federal law or securities exchange and to obtain any such consent or approval of any such governmental authority.

15.
the Plan will govern.

Plan Governs.  This Agreement is subject to all terms and provisions of the Plan.  In the event of a conflict between one or more provisions of this Agreement and one or more provisions of the Plan, the provisions of

16.

Administrator Authority.  The Administrator will have the power to interpret the Plan and this Agreement and to adopt such rules for the administration, interpretation and application of the Plan as are consistent

therewith and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any Market Stock Units have vested).  All actions taken and all interpretations and determinations made by the
Administrator in good faith will be final and binding upon Participant, the Company and all other interested persons.  No member of the Administrator will be personally liable for any action, determination or interpretation made in good
faith with respect to the Plan or this Agreement.

17.

by electronic means or request Participant’s consent to participate in the Plan by electronic means.  Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or
electronic system established and maintained by the Company or another third party designated by the Company.

19.

 Captions.  Captions provided herein are for convenience only and are not to serve as a basis for interpretation or construction of this Agreement.

Agreement Severable.  In the event that any provision in this Agreement will be held invalid or unenforceable, such provision will be severable from, and such invalidity or unenforceability will not be construed to

have any effect on, the remaining provisions of this Agreement.

20.

Section 409A. Notwithstanding anything in the Plan or this Agreement to the contrary, if the vesting of the balance, or some lesser portion of the balance, of the Market Stock Units is accelerated in connection with

Participant’s termination as a Service Provider (provided that such termination is a “separation from service” within the meaning of Section 409A, as determined by the Company), other than due to death, and if (x) Participant is a
“specified employee” within the meaning of Section 409A at the time of such termination as a Service Provider and (y) the payment of such accelerated Market Stock Units will result in the imposition of additional tax under Section 409A
if paid to Participant on or within the six (6) month period following Participant’s termination as a Service Provider, then the payment of such accelerated Market Stock Units will not be made until the date six (6) months and one (1) day
following the date of Participant’s termination as a Service Provider, unless the Participant dies following his or her termination as a Service Provider, in which case, the Market Stock Units will be paid in Shares to the Participant’s estate
as soon as practicable following his or her death. It is the intent of this Agreement to comply with the requirements of Section 409A so that none of the Market Stock Units provided under this Agreement or Shares issuable thereunder will
be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to so comply. For purposes of this Agreement, “Section 409A” means Section 409A of the Code, and any proposed, temporary or
final Treasury Regulations and Internal Revenue Service guidance thereunder, as each may be amended from time to time.

21.

Governing Law.  This Agreement shall be governed by the laws of the State of California, without giving effect to the conflict of law principles thereof.  For purposes of litigating any dispute that arises under this

Award of Market Stock Units or this Agreement, the parties hereby submit to and consent to the jurisdiction of the State of California, and agree that such litigation shall be conducted in the courts of Santa Clara County, California, or the
federal courts for the United States for the Northern District of California, and no other courts, where this Award of Market Stock Units is made and/or to be performed.

of this document. You further agree to accept, acknowledge and execute this Agreement as a condition to receiving any Market Stock Units under this Award.

Nothing in this Notice of Grant or in the attached Agreement or in the Plan shall confer upon Participant any right to continue in service for any period of specific duration or interfere with or
otherwise restrict in any way the rights of the Company (or any Parent or Subsidiary employing or retaining Participant) or of Participant, which rights are hereby expressly reserved by each, to terminate
Participant’s service at any time for any reason, with or without cause.

EXHIBIT A

MARKET STOCK UNIT AGREEMENT

1.

Grant.

(a)    The Company hereby grants to Participant under the Plan an Award of Market Stock Units, subject to all of the terms and conditions in the Notice of Grant, this Agreement and the Plan.

(b)    Subject to Section 3 below, the number of Market Stock Units in which the Participant may vest in accordance with the Vesting Schedule set forth in the Notice of Grant will depend upon the

Company’s Stock Price Performance as compared to the NASDAQ Composite Index Performance calculated on the [____________] (the “Measurement Date”), determined as follows:

(i)    Performance Calculation.

the 30 trading-day period ending [___________] of the year of grant over (ii) the average adjusted closing price of the Company’s common stock during the 30 trading-day period ending on the Measurement Date.

1.    The “Company’s Stock Price Performance” means the percentage increase or decrease in (i) the average adjusted closing price per share of the Company’s common stock during

day period ending February 15 of the year of grant over (ii) the adjusted index value of the NAQDAQ Composite Index during the 30 trading-day period ending on the Measurement Date.

2.    The “NASDAQ Composite Index Performance” means the percentage increase or decrease in (i) the adjusted index value of the NASDAQ Composite Index during the 30 trading-

rate (the “Growth Rate Delta”) equal to the Company’s Stock Price Performance minus the NASDAQ Composite Index Performance. The Growth Rate Delta will be calculated on the Measurement Date.

3.    The Company’s Stock Price Performance will be compared against the NASDAQ Composite Index Performance (each expressed as a growth rate percentage) to result in a growth

(ii)    Market Stock Unit Calculation.

100% of the Target Number of Market Stock Units.

1.    If the Growth Rate Delta is equal to 0%, the number of Market Stock Units that will be eligible to vest (the “Calculated Market Stock Units”) on the Measurement Date will equal

2.    If the Growth Rate Delta is greater or less than 0%, the number of Market Stock Units that will be Calculated Market Stock Units will equal: (i)  the Target Number of Market
Stock Units, multiplied by (ii) the sum of (A) 100% plus (B) three times the Growth Rate Delta; provided, however, that in no event will more than the Maximum Number of Market Stock Units become Calculated
Market Stock Units. If the Growth Rate Delta is less than or equal to negative-33.3%, then the number of Target Market Stock Units that will become Calculated Market Stock Units will equal 0.

(iii)    Examples (for illustration purposes only).

1.    Example #1: If the Growth Rate Delta equaled 20%, then 160% (equal to 100% plus (3 times 20%)) of the Target Number of Market Stock Units would be Calculated Market Stock

Units.

Calculated Market Stock Units.

2.        Example  #2:  If  the  Growth  Rate  Delta  equaled  negative-20%,  then  40%  (equal  to  100%  plus  3  times  negative-20%))  of  the  Target  Number  of  Market  Stock  Units  would  be

2.

Company’s Obligation to Pay. Each Market Stock Unit represents a value equal to the Fair Market Value of a Share on the date it is granted. Unless and until the Market Stock Units will have vested
in the manner set forth in Section 3, Participant will have no right to payment of any such Market Stock Units. Prior to actual payment of any vested Market Stock Units, such Market Stock Unit will represent an
unsecured obligation of the Company, payable (if at all) only from the general assets of the Company. Payment of any vested Market Stock Units will be made in whole Shares only and any fractional Shares will be
forfeited at the time of payment.

3.

Vesting Schedule. The Market Stock Units awarded by this Agreement will vest in Participant according to the Vesting Schedule set forth on the attached Notice of Grant, subject to Participant

continuing to be a Service Provider through the Vesting Date; provided however:

(a)    Upon a Change of Control (as such term is defined in the Participant’s CEO Employment Agreement), and subject to Participant’s continuing to be a Service Provider through such date, the
vesting of the Calculated Market Stock Units will accelerate on a pro rata basis based on (i) the amount of time that has lapsed between the Date of Grant and the date of the closing of the Change of Control relative to
(ii) the original 3-year performance period (with the number of Calculated Market Stock Units eligible to be earned calculated using the amount to be paid to holders of the Company’s Common Stock in the Change of
Control transaction). Any unvested Calculated Market Stock Units that do not accelerate based on the terms of the preceding sentence will vest ratably in substantially equal installments on each anniversary of the
Date of Grant that occurs following the closing date of such Change of Control transaction with the final vesting date to be the 3-year anniversary of the Date of Grant, to the extent any Calculated Market Stock Units
remain outstanding following the Change of Control and subject to Participant continuing to be a Service Provider through the applicable vesting date.

(b)    In the event Participant’s employment with the Company terminates as a result of Participant’s death or Disability (as such term is defined in the Employment Agreement) following the Start Date
(as such term is defined in the Employment Agreement), then, on the date of such termination, Participant will vest in the Calculated Market Stock Units (with the number of Calculated Market Stock Units eligible to
be earned calculated using the date of employment termination as the measurement date for purposes of calculating the Company’s total shareholder return compared to that of the NASDAQ Composite).

(c)        If  upon  or  within  18  months  following  a  Change  of  Control  (as  such  term  is  defined  in  the  CEO  Employment  Agreement)  (i)  the  Company  (or  any  parent  or  subsidiary  or  successor  of  the
Company)  terminates  Participant’s  employment  with  the  Company  other  than  for  Cause  (as  such  term  is  defined  in  the  CEO  Employment  Agreement),  death  or  Disability  (as  such  term  is  defined  in  the  CEO

        
Employment Agreement), or (ii) Participant resigns from such employment for Good Reason (as such term is defined in the CEO Employment Agreement), then, subject to the terms and conditions of Section 8 of the
Employment Agreement, Participant will be entitled to 100% accelerated vesting.

4.

Forfeiture upon Termination of Status as a Service Provider. Subject to Section 3 hereof, if Participant ceases to be a Service Provider for any or no reason, the then-unvested Market Stock Units

awarded by this Agreement will thereupon be forfeited at no cost to the Company and Participant will have no further rights thereunder.

5.

Payment after Vesting. Any Market Stock Units that vest in accordance with Section 3 will be paid to Participant (or in the event of Participant’s death, to his or her estate) in whole Shares, subject to
Participant satisfying any applicable tax withholding obligations as set forth in Section 7. Subject to the provisions of Section 19, any Shares will be issued to Participant as soon as practicable after the relevant vesting
date, but in any event, within the period ending on the later to occur of the date that is two-and-one-half months from the end of (a) Participant’s tax year that includes the vesting date, or (b) the Company’s tax year
that includes the vesting date.

6.

Payments  after  Death.  Any  distribution  or  delivery  to  be  made  to  Participant  under  this  Agreement  will,  if  Participant  is  then  deceased,  be  made  to  Participant’s  designated  beneficiary,  or  if  no
beneficiary  survives  Participant,  the  administrator  or  executor  of  Participant’s  estate.  Any  such  transferee  must  furnish  the  Company  with  (a)  written  notice  of  his  or  her  status  as  transferee,  and  (b)  evidence
satisfactory to the Company to establish the validity of the transfer and compliance with any laws or regulations pertaining to said transfer.

7.

Withholding of Taxes.

(a)    Generally. The Participant is ultimately liable and responsible for all taxes owed in connection with the Market Stock Units, regardless of any action the Company or any of its Subsidiaries takes
with respect to any tax withholding obligations that arise in connection with the Market Stock Units. Neither the Company nor any of its Subsidiaries makes any representation or undertaking regarding the treatment of
any tax withholding in connection with the grant or vesting of the Market Stock Units or the subsequent sale of Shares issuable pursuant to the Market Stock Units. The Company and its Subsidiaries do not commit
and are under no obligation to structure the Market Stock Units to reduce or eliminate the Participant’s tax liability.

(b)    Payment of Withholding Taxes. Notwithstanding any contrary provision of this Agreement, no Shares will be issued to Participant, unless and until satisfactory arrangements (as determined by the
Administrator) will have been made by the Participant with respect to the payment of any taxes which the Company determines must be withheld with respect to the Market Stock Units. The Administrator, in its sole
discretion and pursuant to such procedures as it may specify from time to time, may satisfy such tax withholding obligations, in whole or in part, by withholding otherwise deliverable Shares having an aggregate Fair
Market Value sufficient to (but not exceeding) the minimum amount required to be withheld. In addition and to the maximum extent permitted by law, the Company has the right to retain without notice from salary or
other amounts payable to the Participant, cash having a value sufficient to satisfy any tax withholding obligations that cannot be satisfied by the withholding of otherwise deliverable Shares.

8.

Rights as Stockholder. Neither Participant nor any person claiming under or through Participant will have any of the rights or privileges of a stockholder of the Company in respect of any Shares
deliverable hereunder, unless and until certificates representing such Shares will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to Participant, provided that
the Participant shall be entitled to any award adjustments provided pursuant to Section 18(a) of the Plan.

9.

No Effect on Service. Participant acknowledges and agrees that the vesting of the Market Stock Units pursuant to Section 3 hereof is earned only by Participant continuing to be a Service Provider
through the applicable vesting dates (and not through the act of being hired or acquiring Shares hereunder), subject, however, to the provisions in Section 3(a)-(c) above). Participant further acknowledges and agrees
that this Agreement, the transactions contemplated hereunder and the vesting schedule set forth herein do not constitute an express or implied promise of Participant continuing to be a Service Provider for the vesting
period, for any period, or at all, and will not interfere with the Participant’s right or the right of the Company (or the Affiliate employing or retaining Participant) to terminate Participant as a Service Provider at any
time, with or without cause.

10.

Address for Notices. Any notice to be given to the Company under the terms of this Agreement will be addressed to the Company, in care of Stock Administrator at Align Technology, Inc., 2820
Orchard Parkway, San Jose, CA 95131, or at such other address as the Company may hereafter designate in writing. Any notice to be given to the Participant regarding his Market Stock Unit award shall comply with
the notice provisions in the Participant’s CEO Employment Agreement.

11.

Grant is Not Transferable. Except to the limited extent provided in Section 6, or, in the event of Participant’s death, by his will or the laws of descent or distribution (pursuant to Section 15 of the
Plan) or as otherwise determined by the Plan Administrator (pursuant to Section 15 of the Plan), this grant and the rights and privileges conferred hereby will not be transferred, assigned, pledged or hypothecated in
any way (whether by operation of law or otherwise) and will not be subject to sale under execution, attachment or similar process. Upon any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of this
grant, or any right or privilege conferred hereby, or upon any attempted sale under any execution, attachment or similar process, this grant and the rights and privileges conferred hereby immediately will become null
and void. Notwithstanding the above, the rights relating to Participant’s Restricted Stock Unit grant can be exercised on the Participant’s behalf by his legal representative in the event of his legal incapacity, or, in the
event of his death, by his designated beneficiary (if any) or, if no beneficiary is designated with respect to his Restricted Stock Units, by his estate.

12.

Binding  Agreement.  Subject  to  the  limitation  on  the  transferability  of  this  grant  contained  herein,  this  Agreement  will  be  binding  upon  and  inure  to  the  benefit  of  the  heirs,  legatees,  legal

representatives, successors and assigns of the parties hereto.

13.

Additional Conditions to Issuance of Stock. If at any time the Company will determine, in its discretion, that the listing, registration or qualification of the Shares upon any securities exchange or
under any state or federal law, or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of shares to Participant (or his estate), such issuance will not
occur unless and until such listing, registration, qualification, consent or approval will have been effected or obtained free of any conditions not acceptable to the Company. Where the Company determines that the
delivery of the payment of any Shares will violate federal securities laws or other applicable laws, the Company will defer delivery until the earliest date at which the Company reasonably anticipates that the delivery
of Shares will no longer cause such violation. The Company will make all reasonable efforts to meet the requirements of any such state or federal law or securities exchange and to obtain any such consent or approval
of any such governmental authority. The Company represents and acknowledges that, as of the Date of Grant, there are currently no delivery restrictions in effect of the type referred to in this Section 13.

14.

Plan Governs. This Agreement is subject to all terms and provisions of the Plan. In the event of a conflict between one or more provisions of this Agreement and one or more provisions of the Plan,

the provisions of the Plan will govern.

15.

Administrator Authority. The Administrator will have the power to interpret the Plan and this Agreement and to adopt such rules for the administration, interpretation and application of the Plan as
are consistent therewith and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any Market Stock Units have vested). All actions taken and all interpretations and
determinations made by the Administrator in good faith will be final and binding upon Participant, the Company and all other interested persons. No member of the Administrator will be personally liable for any
action, determination or interpretation made in good faith with respect to the Plan or this Agreement.

16.

Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related to Market Stock Units awarded under the Plan or future Market Stock Units that may be
awarded under the Plan by electronic means or request Participant’s consent to participate in the Plan by electronic means. Participant hereby consents to receive such documents by electronic delivery and agrees to
participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated by the Company.

17.

18.

Captions. Captions provided herein are for convenience only and are not to serve as a basis for interpretation or construction of this Agreement.

Agreement Severable. In the event that any provision in this Agreement will be held invalid or unenforceable, such provision will be severable from, and such invalidity or unenforceability will not

be construed to have any effect on, the remaining provisions of this Agreement.

19.

Section 409A. Notwithstanding anything in the Plan or this Agreement to the contrary, if the vesting of the balance, or some lesser portion of the balance, of the Market Stock Units is accelerated in
connection with Participant’s termination as a Service Provider (provided that such termination is a “separation from service” within the meaning of Section 409A, as determined by the Company), other than due to
death, and if (x) Participant is a “specified employee” within the meaning of Section 409A at the time of such termination as a Service Provider and (y) the payment of such accelerated Market Stock Units would result
in the imposition of additional tax under Section 409A if paid to Participant on or within the six (6) month period following Participant’s termination as a Service Provider, then the payment of such accelerated Market
Stock Units will not be made until the date six (6) months and one (1) day following the date of Participant’s termination as a Service Provider, unless the Participant dies following his or her termination as a Service
Provider, in which case, the Market Stock Units will be paid in Shares to the Participant’s estate as soon as practicable following his or her death. It is the intent of this Agreement to comply with the requirements of
Section 409A so that none of the Market Stock Units provided under this Agreement or Shares issuable thereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be
interpreted  to  so  comply.  For  purposes  of  this  Agreement,  “Section  409A”  means  Section  409A  of  the  Code,  and  any  proposed,  temporary  or  final  Treasury  Regulations  and  Internal  Revenue  Service  guidance
thereunder, as each may be amended from time to time.

20.

Governing Law. This Agreement shall be governed by the laws of the State of California, without giving effect to the conflict of law principles thereof. For purposes of litigating any dispute that
arises under this Award of Market Stock Units or this Agreement, the parties hereby submit to and consent to the jurisdiction of the State of California, and agree that such litigation shall be conducted in the courts of
Santa Clara County, California, or the federal courts for the United States for the Northern District of California, and no other courts, where this Award of Market Stock Units is made and/or to be performed.

[Remainder of Page Intentionally Left Blank]

By Participant’s acceptance of this Agreement, Participant represents that he or she is familiar with the terms and provisions of the Plan, and hereby accepts this Agreement subject to all of the
terms and provisions thereof. Participant has reviewed the Plan and this Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Agreement and fully
understands all provisions of this Agreement. Participant agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Plan or
this Agreement, but does not waive any rights he has under his CEO Employment Agreement. Participant further agrees to notify the Company upon any change in the residence indicated in the Notice of
Grant of Market Stock Units if and to the extent that the Company is not otherwise notified of any such change.

Zelko Relic
[Address Withheld]

Dear Zelko:

This letter of assignment (the "Agreement") is to confirm a mutual understanding between you and Align Technology, Inc (the "Home Company") of the terms and conditions applying to your long-term international
assignment (the "Assignment") to Align Technology Switzerland GmbH (the "Host Company") as outlined below:

CTO and SVP, Global R&D
$440,000 USD

The terms and conditions outlined in this Agreement will be in effect only for the period of your employment on this Assignment. The term of the Assignment may be extended by written agreement of the parties.

During the Assignment, you shall be based at the offices of the Host Company in the Host Location, or at such other location as may be agreed upon by you and the Home Company. You shall, however, also travel to
other locations at such times as may be appropriate for the performance of your duties under this Agreement. During the Assignment, you shall perform services as requested by, and under the sole direction and control
of, the directors, officers and employees of the Host Company, acting only on behalf and for the benefit of the Host Company. In the event this Assignment is extended or a new assignment occurs, a new written
agreement shall be executed. You are subject to reassignment to any of the Home Company’s locations throughout the world. Such reassignment will depend on the future needs of the Home Company.

During the Assignment and any period that you are on assignment for the Home Company outside the Home Location, this Agreement and the benefits contained herein, are contingent upon you being authorized to
work and reside in the Host Location. Home Company (and Host Company if necessary) will support your application for any visas, residence permits or other necessary authorizations.

If you lose or fail to obtain your authorization to work in the Host Location at any time, for any reason during the life of this Agreement or your Assignment, Home Company will consider your circumstances, but
may, at its sole discretion, consider all or any portion of this Agreement void.

The Assignment and Your "At-Will" Employment

Your Assignment is temporary in nature. At all times during your Assignment, you will remain an at-will employee of Home Company. The terms and conditions of your offer letter and proprietary information and
inventions agreement with Home Company (collectively "Offer Letter") will remain applicable, unless modified by this Agreement. This Agreement is based on our confidence that this Assignment and your continued

employment with Home Company will be a mutually rewarding and enriching experience, but it is not an employment contract, and does not represent a guarantee of continued employment for any period of time.
Regardless of any statement contained in this Agreement, your employment with the Home Company is “employment at-will”, which means that either you or the Home Company may terminate your employment
relationship at any time, for any reason, with or without cause, and with or without notice to the other party. Nothing in this Agreement is intended to modify or alter the at-will nature of your employment relationship.
For the avoidance of doubt, this does not in any way give rise to a direct employment relationship between you and the Host Company. Your employment with the Home Company is subject to the laws of the Home
Location. Host Location law shall not apply to this Assignment or the services performed during your Assignment, and you hereby agree to waive all claims under Host Location law, if any.

If you die, become disabled or the Home Company terminates your employment for reason other than for Cause before the end of this Assignment, the Home Company will cover the cost of returning you and your
accompanying family members as well as your personal effects back to the Home Location immediately. "Cause" is determined by the Home Company in its sole discretion, but examples of Cause would include
conduct by you involving dishonesty, failure to follow the “Employment Restrictions” Section below, or failure to abide by any material term of this Agreement or your Offer Letter.

Home Company requires you, during the course of your Assignment, to abide by all requirements set out in the Home Company's International Long Term Assignment Policy (the "Policy"). As part of this, should any
requirement set out in the Policy conflict with any requirement of your employment with the Home Company or the Offer Letter, the former will take precedence to the extent allowed by applicable law.

Depending on the documentation needed to support your Assignment, you may also be required to enter into a local employment agreement with the Host Company covering the period of your Assignment.

Please note that all allowances and benefits provided in this Agreement cease upon your return to the Home Location or upon reassignment to a new location, the terms of this Agreement will cease to have effect and
you will revert to the terms and conditions of your Offer Letter.

Your Assignment to the Host Company may be voluntarily ended by you upon thirty (30) days' prior written notice, or involuntarily ended by either the Home Company or the Host Company, at any time, for any
reason, and without payment of any indemnity by the Home or Host Company unless expressly required by applicable law. If the Home Company or the Host Company ends this Assignment early, it will attempt to
give you thirty (30) days' prior notice, to assist you in preparing for the transition.
If you voluntarily resign from employment with the Home Company while on Assignment, all Assignment-related relocation payments, Assignment-related allowances and Assignment-related support provided under
this Agreement will cease upon the date of resignation to the extent allowed by applicable law. In situations where you voluntarily resign from employment or are involuntarily terminated for "Cause," neither Home
Company nor Host Company will bear any relocation costs, unless expressly required by the law applicable.

For  the  avoidance  of  doubt,  the  termination  of  your  employment  with  the  Home  Company  shall  automatically  terminate  your  Assignment  under  this  Agreement.  If  your  employment  with  the  Home  Company
terminates during the Assignment, the continuing obligations in your Offer Letter will remain in effect.

Further, as a requirement to receive any Assignment-related benefits, you will be required to provide your signed acknowledgement and acceptance of Exhibit B attached herein, which shall be applicable for the
duration of your Assignment to the extent allowed under applicable law.

Employment Restrictions – Conflict of Interest, Compliance with Applicable Laws

It is understood that during your Assignment, and employment with Home Company, you will not engage in any employment or business enterprises that would in any way conflict with your service and the interests
of the Home Company or the Host Company. The Home Company's Code of Conduct, Export/Import, and any other regulation to lawful trade policies apply to all transactions and conflicts of interest. In addition, you
agree to comply with all applicable laws in the Host Location, including all applicable laws concerning governmental payments. Except as permitted under the express written policies of the Home Company, you shall
not, directly or indirectly, pay, give or offer anything of value to any foreign government officer, employee or representative, or to any foreign political party or candidate for or incumbent in any foreign political office,
for any personal or business reasons, including in order to assist in obtaining, retaining or directing business.

Administration

You will continue to be an employee of the Home Company and will continue to be paid by the Home Company from the Home Location payroll. Salary actions, including timing and amounts of increases (if any),
will be consistent with the Home Company’s customary payroll and performance review practices in effect in your Home Location. While on Assignment, incentive payments will be administered and paid according
to the customary incentive policies and practices of the Home Company.

Employee Assignment Benefits

Throughout your Assignment, unless otherwise provided in this Agreement, you shall be entitled to participate in any employee benefit plans, programs or arrangements of the Home Company for which you are
eligible,  as  well  as  any  benefit  plans,  programs  or  arrangements  of  the  Home  Company  designed  to  replace  the  existing  plans,  programs  or  arrangements  during  your  Assignment.  These  benefits  and  assignment
allowances and reimbursements, including those that follow in this Agreement, are excluded from your regular salary and shall not be considered for purposes of determining any notice, overtime, 13 months' pay,
severance, bonus, vacation pay, holiday allowance, or similar to the extent allowed under applicable law. Any severance or severance-related payments that may be payable under any non-U.S. jurisdiction will reduce
the amount payable under the Home Company's prevailing severance or severance-related practices, if any, in the United States.
These Assignment benefits and allowances are provided at the sole discretion of Home Company. You shall not acquire a right to such benefits and allowances, and Home Company reserves the right to change,
modify, amend or discontinue such benefits and allowances at any time, at its sole discretion, to the extent allowed by applicable law. You understand and agree that the benefits provided under your Offer Letter (if
any) and U.S. benefit policies which are directly related to your performance of work in Home Location (e.g. transportation allowance) will cease to apply during your Assignment.

Vacation

You will be eligible for vacation under the Home Company's vacation policy, unless otherwise required by local law.

Holidays

You will be eligible to observe the local policy for holidays in the Host Location.

Taxation

You will be covered by Home Company’s tax equalization policy for the duration of your Assignment. Home Company’s philosophy regarding tax equalization is that as an international assignee, you will neither
materially gain nor lose from the difference in income and social tax costs between your Home and Host Location, within certain parameters. Thus, while on the Assignment, you will pay approximately the same U.S.
income (U.S. federal, state and local) and social security tax, on tax equalized income, which you would have paid had you remained in your Home Location.

You will be required to comply with all Home Location, Host Location and foreign laws regarding personal income and social security taxes and thus you will be responsible for ensuring timely completion of personal
tax returns in the Host and Home locations (as required).

To assist you in this regard, the Home Company will designate a tax service provider and pay for the preparation of required tax returns and tax equalization settlement calculations for you for all tax years affected by
the Assignment. You will be required to meet with the Home Company-designated tax service provider for a tax briefing prior to your departure from the Home Location and after arrival in the Host Location to
confirm that you understand the tax implications of the Assignment. You will be required to use the tax return preparation services of the Home Company’s designated tax service provider. The Home Company will
not reimburse any fees incurred by you in utilizing the services of another tax service provider.

To  the  extent  permissible  under  applicable  laws,  it  is  intended  that  you  will  remain  covered  under  your  Home  Location  social  security  scheme.  However,  if  you  are  subject  to  social  security  charges  in  the  Host
Location during the Assignment, and the Host Location permits you to apply for a refund of such charges, you agree to apply for such refund, and have such refund paid to Host Company or Home Company where
possible. If it is not possible for a refund to go directly to Host Company or Home Company, then you agree and authorize Home Company or Host Company, as applicable, to deduct and set off any such amounts
refunded to you from any payments due from Home Company or Host Company to you, up to the maximum extent permitted by law. If the set-off is insufficient to cover the refund that you received, you agree to pay
the Home Company or Host Company, as applicable, the amount still outstanding.

You will be responsible for penalties and interest charges, if any, incurred as a result of your personal actions.

By accepting this Assignment, you confirm your agreement to the terms and conditions of the Home Company's tax equalization policy including, but not limited to:

A.your agreement to pay hypothetical tax as determined in accordance with the Home Company's tax equalization policy.

B.your authorization that the Home Company may deduct such hypothetical tax from your base salary and other earnings in accordance with your regular payroll schedule.

C.your agreement that any additional hypothetical tax due from you to the Home Company will be settled by you within thirty (30) days.

D.your agreement to provide upon request and on a timely basis all necessary data to enable Home Company’s designated tax service provider to prepare your relevant tax returns in both the Home Location and Host

Location.

E.your agreement to keep your tax return filing obligations in both the Home Location and Host Location up to date and in good order.

F.your agreement to abide by the terms and conditions of the Home Company's tax equalization policy, which shall be evidenced by your signed acknowledgment and acceptance of Exhibit C attached herein.

Assignment Allowances

In addition to your Home Location compensation, you will be entitled to receive the Assignment allowances and provisions as described in the Policy. The amount of each of these allowances is specified in the
Summary of Long Term International Assignment Provisions, attached herein as Exhibit A, and will be reviewed with you by your international assignment consultant.

While you are on the Assignment, all Assignment allowances, deductions and other compensation items referenced herein will be administered by the Home Company from the Home Location payroll.

Severability

The  provisions  of  this  Agreement  are  severable.  If  any  provision  is  found  by  any  court  of  competent  jurisdiction  to  be  unreasonable  and  invalid,  that  determination  shall  not  affect  the  enforceability  of  the  other
provisions. Furthermore, if any of the restrictions against various activities is found to be unreasonable and invalid, the court before which the matter is pending shall enforce the restriction to the maximum extent it
deems to be reasonable or valid.

Governing Law/Venue

This Agreement and all related matters in dispute thereto shall be construed in accordance with California State substantive law without regard to the choice of law principles thereof.

All questions concerning the construction, validity and interpretation of this Agreement arising during the period of this Agreement and/or directly or indirectly relating to or arising out of the Assignment including,
but not limited to, claims of discrimination arising under state or federal law, the termination thereof, and/or to the interpretation and/or implementation of this Agreement, will exclusively be subject to arbitration. The
arbitration will be held in California in the United States of America, and will be governed by the rules as established at that time by the American Arbitration Association for the resolution of employment disputes.

To the extent that you are entitled to rights, benefits or compensation under the laws of both Host Location and your Home Location, you agree that you will be entitled to such rights, benefits, or compensation that are
no greater than those provided to you under the terms of this Agreement, so that any advantages, entitlements or protections that may apply to you under the laws of both jurisdictions may not be combined.

No Waiver

No failure or delay by any party in exercising any right, power or remedy under this Agreement shall operate as a waiver thereof, nor shall any single or particular exercise of the same preclude any further exercise
thereof or the exercise of any other right, power or remedy. Without limiting the foregoing, no waiver by any party of any breach of any provision of this Agreement shall be deemed to be a waiver of any subsequent
breach of that or any other provision of this Agreement.

Withholding/Deductions

All amounts paid pursuant to this Agreement shall be subject to deductions and withholding for taxes (income, social, foreign or otherwise) to the extent agreed to by you or required by applicable law.

Internal Revenue Code Section 409A

Certain payments, reimbursements, and benefits to be made to you under this Agreement may be subject to Section 409A of the U.S. Internal Revenue Code (“Section 409A”). The Home Company intends that this
Agreement will be administered and interpreted in accordance with Section 409A so that amounts payable under the Agreement shall be exempt or compliant with Section 409A. If any provision of this Agreement is
ambiguous as to its compliance with Section 409A, the provision shall be read in such a manner so that all payments comply with Section 409A. Any benefits or amounts payable under this Agreement upon your
termination of employment that constitute deferred compensation under Section 409A (i) shall be paid only if such termination constitutes a separation from service under Section 409A, and (ii) if you are a “specified
employee”, the payment shall be delayed until six months and one day from the date of termination of employment.

Any  reimbursement  of  benefits  will  be  made  not  later  than  the  last  day  of  your  taxable  year  following  the  year  in  which  the  related  expense  was  incurred  (subject  to  you  providing  any  required  supporting
documentation) in accordance with Treas. Reg. Section 409A-3(i)(1)(iv). Any reimbursement payments due to you shall not be subject to liquidation or exchange for another benefit and the amount of such expenses
eligible for reimbursement or such benefits that you receive in one taxable year shall not affect the expenses eligible for reimbursement or the amount of such benefits that you will receive in any other taxable year.

Any amounts payable to you pursuant to any tax equalization agreement (within the meaning of Treas. Reg. Section 1.409A-1(b)(8)(iii)) shall be made not later than the last day of your second taxable year following
the year in which your U.S. Federal income tax return is required to be filed (including any extensions) for the year to which the compensation subject to the tax equalization payment relates, or, if later, the second
taxable year following the latest such taxable year in which your foreign tax return or payment is required to be filed or made for the year to which the compensation subject to the tax equalization payment relates. In
the event of a tax audit, litigation or other tax proceedings related to the Policy, supplemental tax equalization payments may be made during the period described in Treas. Reg. Section 1.409A-3(i)(1)(v).

The  Home  Company  makes  no  representation  or  warranty  and  shall  have  no  liability  to  you  or  any  other  person  if  any  provision  of  the  Agreement,  the  Policy  or  the  Home  Company's  tax  equalization  policy  is
determined to constitute deferred compensation subject to Section 409A but does not satisfy an exemption from, or the conditions of, Section 409A.

During the Assignment, your confidentiality obligations towards the Home Company will remain unaffected by your Assignment (and they extend to the Host Company during your Assignment). Upon termination of
your employment and/or Assignment, you must return all copies of documents containing Confidential Information, as well as all Home or Host Company assets and property, including documents (in electronic or

Home Leave

Cost of Living Allowance (COLA)

Host Location Housing Allowance

You are eligible to take two (2) annual home leaves for every twelve (12) months on Assignment. Annual home
leave is provided to enable you to:

•    renew ties with friends / family
•    keep abreast of the social, cultural, political and economic environment in the Home Location
•    visit the Home Location to sustain contacts with associates, discuss career development issues and facilitate

Reimbursable expenses are: Airfare and ground transportation to/from the airport for you in accordance with
the Home Company's travel policy.

Such payment will be made by Aires upon submission of
expense report and receipts.

You may receive a Cost of Living Allowance (COLA) of $7,000 USD per month to assist in maintaining a style
of living comparable to that in the Home Location. The COLA is based on indices supplied to Home Company
by a third party international data consultant. This source prices the differences in goods and services between
the  Home  and  Host  Location,  factoring  in  current  exchange  rates.  Your  salary  and  family  size  at  the  Host
Location are used to calculate the COLA.

The COLA is calculated at the start of your Assignment and
is reviewed periodically to adjust the differential up or down
if necessary. It may be brought about by changes in base
salary, Host Location, family size and extreme fluctuations in
inflation or exchange rates.

Should your marital status and family size change during the course of your Assignment, it is your
responsibility to immediately notify Home Company of changes in marital status and family size.

The  COLA  will  be  paid  as  part  of  the  Home  Company's
normal payroll cycle and will be grossed up for taxes.

Home Company will provide assistance with housing in the Host Location in the form of a housing allowance
in the amount of 6,000 CHF per month to cover the cost of reasonable housing. If utilities are not included in
the rent, the Home Company will also cover the expenses for the actual utility costs such as electricity, gas, oil,
and/or water.

If you choose to rent housing that is more expensive than the limits set by Home Company, the additional costs
will be your responsibility.

Housing costs are determined based on base salary and
family size by an outside consultant. The housing allowance
will be paid to you as part of the Home Company's normal
payroll cycle or directly to the landlord if deemed beneficial
for tax purposes. These amounts will be grossed up for taxes.

The security deposit for the rental property will be advanced to you by Home Company and is expected to be
repaid in full once the lease has terminated. Please note that any damage to the property, beyond normal wear
and tear, will be your responsibility.

Applicable utilities such as gas, electric, etc. will also be paid
by Home Company as an allowance as part of the Home
Location's normal payroll cycle and will be grossed up for
taxes.

Host Location Transportation

An allowance of $1,771 USD per month will be provided for the lease of an automobile.

Customary local rental agent fees associated with acquiring the Host Location rental will be paid by Home
Company.

The maximum amount of such payment will be determined
by third party recommendations.

            
 
Hypothetical Tax
(Deduction)

Income Tax Preparation/Equalization

Home Company's tax service provider will calculate the estimated hypothetical taxes that will be deducted from
your compensation. This hypothetical tax will be calculated on your non-Assignment related compensation
(i.e., base salary, bonus, etc.) and is in lieu of actual income tax withholding. This is defined as the Home
Location tax that would have been payable on these elements of your remuneration package had you remained
working and resident in your Home Location.

Home  Company  will  pay  the  reasonable  and  customary  costs  of  Home  Company's  tax  provider  for  the
preparation and filing of the Host Location (and Home Location where applicable), tax returns and consulting
services  for  the  duration  of  the  Assignment.  In  addition,  the  Home  Company's  tax  provider  will  handle  any
inquiries from taxing authorities which relate to your Assignment.

The  intent  of  the  Home  Company's  tax  equalization  policy  is  that  your  ultimate  tax  burden  while  on
Assignment will be approximately the same as the tax burden that you would have incurred had you remained
in the Home Location. The Home Company's tax equalization policy is designed and intended to yield neither
an economic benefit nor economic detriment to you as a result of having gone on assignment.

The transportation allowance is provided on a monthly basis,
it will be paid as part of the Home Company's normal pay
cycle and will be grossed up for taxes.

The hypothetical taxes will be deducted from your base
salary as part of the Home Company's normal payroll cycle
while on Assignment.

The tax preparation services will be provided for all years in
which you are covered by the Assignment program, including
the year of repatriation, and any year following your
repatriation if there is still residual Assignment related
income and/or significant foreign tax credits in effect. In
addition, the Home Company tax provider will handle any
inquiries from taxing authorities which relate to your
Assignment.

The fees for this service will be direct billed to Home
Company.

transportation, en-route expenses).

your Host Location or after arriving in your Home Location or new assignment location for a maximum of sixty
(60) days.

party recommendations.

expense report and receipts.

RELOCATION ACKNOWLEDGMENT CLAUSE

I understand and agree that all relocation/allowance payments and benefits related to my Assignment made to me or on my behalf by Home Company prior to the completion of twenty four (24) months of service on
Assignment, measured from the Effective Date, shall not be considered "earned" until twenty four (24) months of employment with the Home Company on Assignment have been completed.

In the event I am involuntarily terminated for "Cause" or voluntarily resign from my employment with Home Company, Home Company will not assume the cost for return transportation to the Home Location or
return shipment of furniture, household goods, or personal effects except where mandated by applicable law. Should I choose to remain in the Host Location, my tax equalization calculation, calculated pursuant to the
Home  Company's  tax  equalization  policy,  will  assume  that  I  left  the  Host  Location  within  thirty  (30)  days  of  such  resignation.  Should  I  be  involuntarily  terminated  for  "Cause"  or  voluntarily  resign  from  my
employment with Home Company within the first twelve (12) months of the Effective Date, I will be required to repay 100% of the relocation/assignment costs and benefits related to my Assignment, to the extent
allowed under applicable law. Should I be involuntarily terminated for "Cause" or voluntarily resign from my employment with Home Company between twelve (12) and twenty-four (24) months of the Effective Date,
I will be required to repay 50% of the relocation/assignment costs related to the Assignment to the extent allowed under applicable law.

In the event of involuntary termination due to performance issues and/or job restructuring, no reimbursement is required.

In accordance with the above, if my employment with Home Company terminates prior to the completion of twenty four (24) months of service on Assignment, measured from the Effective Date, I authorize at the
time of termination of my employment Home Company to withhold from my final pay check any Assignment-related monies due to Home Company, if any, in accordance with the formula stated above, in the above
described scenarios. In the event the amount I owe Home Company is greater than the amount of my final pay check, I agree to pay the balance in full to Home Company within thirty (30) days of my termination date.

Exhibit C

INTERNATIONAL ASSIGNMENT TAX EQUALIZATION POLICY AGREEMENT
I accept that all interpretations under this International Assignment Tax Equalization Policy Agreement, shall be controlled by the Home Company. Home Company shall have the right and privilege at any time it
deems necessary and proper to amend, add, or delete provisions to and from this International Assignment Tax Equalization Policy Agreement, without prior notice.

In addition, I understand, as the employee, I am fully responsible for all penalties and interest charges assessed by any tax authority due to my failure to (1) provide information to the Home Company's designated tax
services provider on a timely basis, (2) notify the Home Company's designated tax services provider of any significant personal income or investment transactions, or (3) cooperate with the Home Company with
respect to the tax equalization process.

I understand and agree that, to the extent allowed by applicable law, Home Company will reduce my compensation by an estimated hypothetical tax. The estimated hypothetical tax is an amount which approximates
my periodic tax deductions/withholdings, if applicable, calculated with reference to compensation, benefits, deductions and credits otherwise available to me had I remained in my Home Location. In return, Home
Company will advance wages that I have not yet earned to assist with the payment of my actual Home and Host Location tax liabilities.

I  understand  that  these  wage  advances  provided  by  the  Home  Company  for  payment  of  taxes  constitutes  an  obligation  by  me  to  Home  Company,  which  will  be  reconciled  with  the  final  liabilities  that  are  Home
Company's responsibility through the annual tax equalization settlement calculation. After completion of the tax equalization settlement statement for each taxable year, I agree to repay any obligation for each taxable
year within thirty (30) days. If I fail to repay any obligation to Home Company within thirty (30) days after completion of the tax equalization settlement statement, then, unless Home Company and I have agreed
otherwise in writing, Home Company shall have the right, to the extent allowed under applicable law, to:

a)Reduce any Assignment-related allowances or reimbursements due to me, and/or

a)    Reduce future amounts paid to me whether as wages, salary or other compensation for services performed in light of my having received wage advances that I have not yet earned.

The total obligation will become immediately due and payable if my employment with Home Company or any of its affiliate corporations is terminated, whether voluntarily or involuntarily, to the extent allowed under
applicable law.

If I fail to furnish tax records in response to a request by the Home Company, or cease employment with the Home Company or any of its subsidiaries for any reason before the tax records needed to complete the year-
end tax equalization settlement statement, then Home Company shall have the right to calculate such amounts by making reasonable assumptions of probable taxes. If an amount is owed to Home Company, Home
Company shall also have the right to require immediate payment of such amount, including the right to reduce future amounts paid to me whether as wages, salary or other compensation for services performed in light
of my having received wage advances that I have not yet earned, unless Home Company and I have agreed otherwise in writing.

By signing, I accept all terms and conditions of this International Assignment Tax Equalization Policy Agreement.

ALIGN TECHNOLOGY, INC.

AMENDED AND RESTATED 2005 INCENTIVE PLAN
EXHIBIT A

OFFICER APPOINTED PRIOR TO SEPTEMBER 2016

RESTRICTED STOCK UNIT AGREEMENT

1.    Grant. The Company hereby grants to Participant under the Plan an Award of Restricted Stock Units, subject to all of the terms and conditions in the Notice of Grant, this Agreement and

the Plan.

2.    Company’s Obligation to Pay. Each Restricted Stock Unit represents a value equal to the Fair Market Value of a Share on the date it becomes vested. Unless and until the Restricted Stock
Units will have vested in the manner set forth in Sections 3 and 4, Participant will have no right to payment of any such Restricted Stock Units. Prior to actual payment of any vested Restricted Stock
Units, such Restricted Stock Unit will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company.

3.    Vesting Schedule. Subject to Section 4, the Restricted Stock Units awarded by this Agreement will vest in Participant according to the vesting schedule set forth on the attached Notice of
Grant, subject to Participant continuing to be a Service Provider through each such date; provided, however, that the paragraph (c) of the Notice of Grant shall apply in the event Participant ceases to
be  a  Service  Provider  as  a  result  of  termination  without  Cause  (as  defined  in  the  employment  agreement  between  the  Company  and  Participant  (the  “Employment  Agreement”)  or  if  Participant
resigns for Good Reason (as defined in the Employment Agreement) and paragraph (d) of the Notice of Grant shall apply in the event Participant ceases to be a Service Provider within 12 months of
a Change of Control (as defined in the Employment Agreement) as a result of termination by the Company without cause or if Participant resigns for Good Reason.

4.    Forfeiture upon Termination of Status as a Service Provider. Subject to paragraphs (c) and (d) of the Notice of Grant, if Participant ceases to be a Service Provider for any or no reason,

the then-unvested Restricted Stock Units awarded by this Agreement will thereupon be forfeited at no cost to the Company and Participant will have no further rights thereunder.

5.    Payment after Vesting. Any Restricted Stock Units that vest in accordance with Section 3 will be paid to Participant (or in the event of Participant’s death, to his or her estate) in whole

Shares, subject to Participant satisfying any applicable tax withholding obligations as set forth in Section 7.

6.    Payments after Death. Any distribution or delivery to be made to Participant under this Agreement will, if Participant is then deceased, be made to Participant’s designated beneficiary, or
if no beneficiary survives Participant, the administrator or executor of Participant’s estate. Any such transferee must furnish the Company with (a) written notice of his or her status as transferee, and
(b) evidence satisfactory to the Company to establish the validity of the transfer and compliance with any laws or regulations pertaining to said transfer.

7.    Taxes.

(a)    Generally. The Participant is ultimately liable and responsible for all taxes owed in connection with the Restricted Stock Units, regardless of any action the Company or any of its
Subsidiaries takes with respect to any tax withholding obligations that arise in connection with the Restricted Stock Units. Neither the Company nor any of its Subsidiaries makes any representation
or undertaking regarding the treatment of any tax withholding in connection with the grant or vesting of the Restricted Stock Units or the subsequent sale of Shares issuable pursuant to the Restricted
Stock Units. The Company and its Subsidiaries do not commit and are under no obligation to structure the Restricted Stock Units to reduce or eliminate the Participant’s tax liability.

(b)    Payment of Withholding Taxes. Notwithstanding any contrary provision of this Agreement, no Shares will be issued to the Participant, unless and until satisfactory arrangements
(as determined by the Administrator) will have been made by the Participant with respect to the payment of any taxes which the Company determines must be withheld with respect to the Restricted
Stock Units. The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to time, may satisfy such tax withholding obligations, in whole or in part, by
withholding otherwise deliverable Shares having an aggregate Fair Market Value sufficient to (but not exceeding) the minimum amount required to be withheld. In addition and to the maximum
extent permitted by law, the Company has the right to retain without notice from salary or other amounts payable to the Participant, cash having a value sufficient to satisfy any tax withholding
obligations that cannot be satisfied by the withholding of otherwise deliverable Shares.

8.    Rights as Stockholder. Neither Participant nor any person claiming under or through Participant will have any of the rights or privileges of a stockholder of the Company in respect of any
Shares deliverable hereunder, unless and until certificates representing such Shares will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to
Participant.

9.    No Effect on Service. Participant acknowledges and agrees that the vesting of the Restricted Stock Units pursuant to Section 3 hereof is earned only by Participant continuing to be a
Service Provider through the applicable vesting dates (and not through the act of being hired or acquiring Shares hereunder) (subject, however, to paragraphs (c) and (d) of the Notice of Grant).
Participant further acknowledges and agrees that this Agreement, the transactions contemplated hereunder and the vesting schedule set forth herein do not constitute an express or implied promise of
Participant continuing to be a Service Provider for the vesting period, for any period, or at all, and will not interfere with the Participant’s right or the right of the Company (or the Affiliate employing
or retaining Participant) to terminate Participant as a Service Provider at any time, with or without cause.

10.        Address  for  Notices.  Any  notice  to  be  given  to  the  Company  under  the  terms  of  this  Agreement  will  be  addressed  to  the  Company,  in  care  of  Stock  Administrator  at  Align

Technology, Inc., 2820 Orchard Parkway, San Jose, CA 95131, or at such other address as the Company may hereafter designate in writing.

11.    Grant is Not Transferable. Except  to  the  limited  extent  provided  in  Section  6,  this  grant  and  the  rights  and  privileges  conferred  hereby  will  not  be  transferred,  assigned,  pledged  or
hypothecated in any way (whether by operation of law or otherwise) and will not be subject to sale under execution, attachment or similar process. Upon  any  attempt  to  transfer,  assign,  pledge,
hypothecate or otherwise dispose of this grant, or any right or privilege conferred hereby, or upon any attempted sale under any execution, attachment or similar process, this grant and the rights and
privileges conferred hereby immediately will become null and void.

12.    Binding Agreement. Subject to the limitation on the transferability of this grant contained herein, this Agreement will be binding upon and inure to the benefit of the heirs, legatees, legal

representatives, successors and assigns of the parties hereto.

13.    Additional Conditions to Issuance of Stock. If at any time the Company will determine, in its discretion, that the listing, registration or qualification of the Shares upon any securities
exchange or under any state or federal law, or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of shares to Participant (or his
estate),  such  issuance  will  not  occur  unless  and  until  such  listing,  registration,  qualification,  consent  or  approval  will  have  been  effected  or  obtained  free  of  any  conditions  not  acceptable  to  the
Company. Where  the  Company  determines  that  the  delivery  of  the  payment  of  any  Shares  will  violate  federal  securities  laws  or  other  applicable  laws,  the  Company  will  defer  delivery  until  the
earliest date at which the Company reasonably anticipates that the delivery of Shares will no longer cause such violation. The Company will make all reasonable efforts to meet the requirements of
any such state or federal law or securities exchange and to obtain any such consent or approval of any such governmental authority.

14.    Plan Governs. This Agreement is subject to all terms and provisions of the Plan. In the event of a conflict between one or more provisions of this Agreement and one or more provisions

of the Plan, the provisions of the Plan will govern.

15.    Administrator Authority. The Administrator will have the power to interpret the Plan and this Agreement and to adopt such rules for the administration, interpretation and application of
the Plan as are consistent therewith and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any Restricted Stock Units have vested). All actions
taken and all interpretations and determinations made by the Administrator in good faith will be final and binding upon Participant, the Company and all other interested persons. No member of the
Administrator will be personally liable for any action, determination or interpretation made in good faith with respect to the Plan or this Agreement.

16.    Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related to Restricted Stock Units awarded under the Plan or future Restricted Stock Units
that may be awarded under the Plan by electronic means or request Participant’s consent to participate in the Plan by electronic means. Participant hereby consents to receive such documents by
electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated by the Company.

17.    Captions. Captions provided herein are for convenience only and are not to serve as a basis for interpretation or construction of this Agreement.

18.        Agreement  Severable.  In  the  event  that  any  provision  in  this  Agreement  will  be  held  invalid  or  unenforceable,  such  provision  will  be  severable  from,  and  such  invalidity  or

unenforceability will not be construed to have any effect on, the remaining provisions of this Agreement.

19.    Governing Law. This Award Agreement shall be governed by the laws of the State of California, without giving effect to the conflict of law principles thereof. For purposes of litigating
any  dispute  that  arises  under  this  Award  of  Restricted Stock Units  or  this  Agreement,  the  parties  hereby  submit  to  and  consent  to  the  jurisdiction  of  the  State  of  California,  and  agree  that  such
litigation shall be conducted in the courts of Santa Clara County, California, or the federal courts for the United States for the Northern District of California, and no other courts, where this Award of

Participant:      
Address:    

You (the “Participant”) have been granted an award (“Award”) of market-performance based Restricted Stock Units (“Market Stock Units”), subject to the terms and conditions of the Plan, this Notice of Grant and the Market

Stock Unit Agreement attached hereto as Exhibit A (the “Agreement”) as follows:

Date of Grant:                February 20, _____

Performance Period:

Performance Matrix:

Vesting Schedule:

Means the three year period commencing on February 15 of the year of grant and ending on the third year anniversary of such date (subject to Sections 4 and 5 of Exhibit A (the
“Performance Period”)).

The number of Market Stock Units in which Participant may vest in accordance with the Vesting Schedule will depend upon the Company’s Stock Price Performance (as defined below)

Subject to Sections 4 and 5 of Exhibit A and the terms of the Plan, the Participant will vest in his or her Calculated Market Stock Units (as defined below) on third-year anniversary of
the date of grant (the “Vesting Date”).

You further agree to accept, acknowledge and execute this Agreement as a condition to receiving any Market Stock Units under this Award.

or without cause.

EXHIBIT A

MARKET STOCK UNIT AGREEMENT

1.

Grant. 

(a)

(b)

The Company hereby grants to Participant under the Plan an Award of Market Stock Units, subject to all of the terms and conditions in the Notice of Grant, this Agreement and the Plan.

The number of Market Stock Units in which the Participant may vest in accordance with the Vesting Schedule set forth in the Notice of Grant will depend upon the Company’s Stock Price

Performance as compared to the NASDAQ Composite Index Performance calculated on February 15, 2022 (the “Measurement Date”) with 100% of the Market Stock Units eligible to vest on the Vesting Date. The actual number of Market
Stock Units that will vest on the Vesting Date will be determined as follows:

(i)    Performance Calculation.

1.    The “Company’s Stock Price Performance” means the percentage increase or decrease in (i) the average adjusted closing price per share of the Company’s common stock during the 30 trading-day

period ending on February 15 of the year of grant over (ii) the average adjusted closing price of the Company’s common stock during the 30 trading-day period ending on the Measurement Date.. Notwithstanding the foregoing, in the event
of a Change of Control of the Company, the “Company’s Stock Price Performance” means the percentage increase or decrease in (i) the average adjusted closing price per share of the Company’s common stock during the 30 trading-day
period ending on February 15 of the year of grant over (ii) the per share value of the Company’s common stock paid to its stockholders in connection with the Change of Control.

on February 15 of the year of grant over (ii) the adjusted index value of the NAQDAQ Composite Index during the 30 trading-day period ending on the Measurement Date.

2.    The “NASDAQ Composite Index Performance” means the percentage increase or decrease in (i) the adjusted index value of the NASDAQ Composite Index during the 30 trading-day period ending

Rate Delta”) equal to the Company’s Stock Price Performance minus the NASDAQ Composite Index Performance. The Growth Rate Delta will be calculated on the Measurement Date.

3.    The Company’s Stock Price Performance will be compared against the NASDAQ Composite Index Performance (each expressed as a growth rate percentage) to result in a growth rate (the “Growth

(ii)    Market Stock Unit Calculation.

Number of Market Stock Units.

1.    If the Growth Rate Delta is equal to 0%, the number of Market Stock Units that will be eligible to vest (the “Calculated Market Stock Units”) on the Vesting Date will equal 100% of the Target

Stock Units, multiplied by (ii) the sum of (A) 100% plus (B) three times the Growth Rate Delta; provided, however, that in no event will more than the Maximum Number of Market Stock Units become Calculated Market Stock Units on
the Vesting Date. If the Growth Rate Delta is equal to negative-33.3%, then the number of Target Market Stock Units that will become Calculated Market Stock Units on the Vesting Date will equal 0.

2.    If the Growth Rate Delta is greater or less than 0%, the number of Market Stock Units that will be Calculated Market Stock Units on the Vesting Date will equal: (i) the Target Number of Market

(iii)    Examples (for illustration purposes only).

1.

2.

If the Growth Rate Delta on the Measurement Date equaled 20%, then 160% (equal to 100% plus (3 times 20%)) of the Target Number of Market Stock Units would be Calculated Market Stock
Units and would vest on the Vesting Date.

If the Growth Rate Delta on the Measurement Date equaled negative-20%, then 40% (equal to 100% plus (3 times negative-20%)) of the Target Number of Market Stock Units would be Calculated
Market Stock Units and would vest on the Vesting Date.

2.

Company’s Obligation to Pay.  Each Market Stock Unit represents a value equal to the Fair Market Value of a Share on the date it is granted.  Unless and until the Market Stock Units will have vested in the manner set

forth in Sections 3, 4 and 5, Participant will have no right to payment of any such Market Stock Units.  Prior to actual payment of any vested Market Stock Units, such Market Stock Unit will represent an unsecured obligation of the
Company, payable (if at all) only from the general assets of the Company. Payment of any vested Market Stock Units will be made in whole Shares only and any fractional Shares will be forfeited at the time of payment.

3.

Vesting Schedule.  Subject to Section 6, the Market Stock Units awarded by this Agreement will vest in Participant according to the Vesting Schedule set forth on the attached Notice of Grant, subject to Participant

continuing to be a Service Provider through each such date.

4.

Change of Control. In the event of a Change of Control, the Performance Period shall be deemed to end upon the closing of the Change of Control for purposes of determining the Company’s Stock Price Performance

and the NASDAQ Composite Index Performance and the number of Market Stock Units that are Calculated Market Stock Units will be determined in accordance with the Performance Matrix and Section 1 of this Exhibit A. The
Participant shall vest in the number of Calculated Market Stock Units determined based on the preceding sentence as follows:

(a)    On the date of, and contingent upon, the Change of Control, Participant will vest in that number of Calculated Market Stock Units equal to (i) (A) the number of calendar months (including any partial month) that
have elapsed from the commencement of the Performance Period through the date of the Change of Control, (B) divided by 36, multiplied by (ii) the number of Calculated Market Stock Units, with the result rounded down to the nearest
whole Share.

(b)    The Calculated Market Stock Units that do not vest pursuant to Section 4(a) will vest on the Vesting Date, unless vested earlier in accordance with the terms of this Award, Section 18 of the Plan or any employment

or other change in control agreement by and between the Company and Participant.

(c)    Notwithstanding the foregoing, if Participant’s employment is terminated without Cause or for Good Reason (as such terms are defined in Participant’s individual employment agreement with the Company) within
twelve months following the occurrence of a Change of Control, then 100% of his or her unvested Calculated Market Stock Units will fully vest, provided the Participant executes and does not revoke a release of claims as provided for in
Participant’s employment agreement (as a necessary condition to the receipt of severance thereunder).

(d)    In accordance with Section 1 of this Exhibit A, the Administrator shall not be entitled to eliminate or reduce the number of Calculated Market Stock Units determined in accordance with Section 1of Exhibit A

following a Change of Control.

 
        
 
 
    
 
 
 
 
 
 
 
 
5.

Termination without Cause or a Resignation for Good Reason Not Following a Change of Control. In the event Participant’s employment with the Company is terminated without Cause or if Participant terminates his

or her employment for Good Reason (as such terms are defined in Participant’s individual employment agreement with the Company) and such termination does not occur on or within twelve months following a Change of Control, the
Performance Period shall be deemed to end upon the Participant’s employment termination date for purposes of determining the Company’s Stock Price Performance and the NASDAQ Composite Index Performance and the number of
Market Stock Units that are Calculated Market Stock Units will be determined in accordance with the Performance Matrix and Section 1 of this Exhibit A. Subject to Participant executing and not revoking a release of claims as provided
for in Participant’s employment agreement (as a necessary condition to the receipt of severance thereunder), Participant shall vest in that number of Calculated Market Stock Units equal to (i) (A) the number of months (including any
partial month, expressed as a fraction) that have elapsed from the commencement of the Performance Period through the date of the termination of employment, (B) divided by 36, multiplied by (ii) the number of Calculated Market Stock
Units, with the result rounded down to the nearest whole Share. The remaining unvested Calculated Market Stock Units will be forfeited at no cost to the Company and Participant will have no further rights thereunder.

6.

Forfeiture upon Termination of Status as a Service Provider.  Subject to the provisions of Section 4 and 5, if Participant ceases to be a Service Provider for any or no reason, the then-unvested Market Stock Units

awarded by this Agreement will thereupon be forfeited at no cost to the Company and Participant will have no further rights thereunder.

7.

Payment after Vesting.  Any Market Stock Units that vest in accordance with Sections 3, 4 and 5 will be paid to Participant (or in the event of Participant’s death, to his or her estate) in whole Shares, subject to

Participant satisfying any applicable tax withholding obligations as set forth in Section 9. Subject to the provisions of Section 21, any Shares will be issued to Participant as soon as practicable after the relevant vesting date, but in any
event, within the period ending on the later to occur of the date that is two-and-one-half months from the end of (a) Participant’s tax year that includes the vesting date, or (b) the Company’s tax year that includes the vesting date.

8.

Payments after Death.  Any distribution or delivery to be made to Participant under this Agreement will, if Participant is then deceased, be made to Participant’s designated beneficiary, or if no beneficiary survives

Participant, the administrator or executor of Participant’s estate.  Any such transferee must furnish the Company with (a) written notice of his or her status as transferee, and (b) evidence satisfactory to the Company to establish the validity
of the transfer and compliance with any laws or regulations pertaining to said transfer.

9.

Withholding of Taxes. 

(a) Generally. The Participant is ultimately liable and responsible for all taxes owed in connection with the Market Stock Units, regardless of any action the Company or any of its Subsidiaries takes with respect to any

tax withholding obligations that arise in connection with the Market Stock Units. Neither the Company nor any of its Subsidiaries makes any representation or undertaking regarding the treatment of any tax

withholding in connection with the grant or vesting of the Market Stock Units or the subsequent sale of Shares issuable pursuant to the Market Stock Units. The Company and its Subsidiaries do not commit and are

under no obligation to structure the Market Stock Units to reduce or eliminate the Participant’s tax liability.

(b) Payment of Withholding Taxes. Notwithstanding any contrary provision of this Agreement, no Shares will be issued to Participant, unless and until satisfactory arrangements (as determined by the Administrator) will
have been made by the Participant with respect to the payment of any taxes which the Company determines must be withheld with respect to the Market Stock Units. The Administrator, in its sole discretion and

pursuant to such procedures as it may specify from time to time, may satisfy such tax withholding obligations, in whole or in part, by withholding otherwise deliverable Shares having an aggregate Fair Market Value

sufficient to (but not exceeding) the minimum amount required to be withheld. In addition and to the maximum extent permitted by law, the Company has the right to retain without notice from salary or other

amounts payable to the Participant, cash having a value sufficient to satisfy any tax withholding obligations that cannot be satisfied by the withholding of otherwise deliverable Shares.

10.

Rights as Stockholder.  Neither Participant nor any person claiming under or through Participant will have any of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable

hereunder, unless and until certificates representing such Shares will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to Participant.

11.

No Effect on Service.  Participant acknowledges and agrees that the vesting of the Market Stock Units pursuant to Sections 3, 4 or 5 hereof is earned only by Participant continuing to be a Service Provider through the

applicable vesting dates (and not through the act of being hired or acquiring Shares hereunder).  Participant further acknowledges and agrees that this Agreement, the transactions contemplated hereunder and the vesting schedule set forth
herein do not constitute an express or implied promise of Participant continuing to be a Service Provider for the vesting period, for any period, or at all, and will not interfere with the Participant’s right or the right of the Company (or the
Affiliate employing or retaining Participant) to terminate Participant as a Service Provider at any time, with or without cause.

12.

Address for Notices.  Any notice to be given to the Company under the terms of this Agreement will be addressed to the Company, in care of Stock Administrator at Align Technology, Inc., 2560 Orchard Parkway,

San Jose, CA 95131, or at such other address as the Company may hereafter designate in writing.

13.

Grant is Not Transferable.  Except to the limited extent provided in Section 8, this grant and the rights and privileges conferred hereby will not be transferred, assigned, pledged or hypothecated in any way (whether by

operation of law or otherwise) and will not be subject to sale under execution, attachment or similar process.  Upon any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of this grant, or any right or privilege conferred
hereby, or upon any attempted sale under any execution, attachment or similar process, this grant and the rights and privileges conferred hereby immediately will become null and void.

14.

Binding Agreement.  Subject to the limitation on the transferability of this grant contained herein, this Agreement will be binding upon and inure to the benefit of the heirs, legatees, legal representatives, successors

and assigns of the parties hereto.

15.

Additional Conditions to Issuance of Stock.  If at any time the Company will determine, in its discretion, that the listing, registration or qualification of the Shares upon any securities exchange or under any state or

federal law, or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of shares to Participant (or his estate), such issuance will not occur unless and until such listing,
registration, qualification, consent or approval will have been effected or obtained free of any conditions not acceptable to the Company.  Where the Company determines that the delivery of the payment of any Shares will violate federal
securities laws or other applicable laws, the Company will defer delivery until the earliest date at which the Company reasonably anticipates that the delivery of Shares will no longer cause such violation.  The Company will make all
reasonable efforts to meet the requirements of any such state or federal law or securities exchange and to obtain any such consent or approval of any such governmental authority.

16.
the Plan will govern.

Plan Governs.  This Agreement is subject to all terms and provisions of the Plan.  In the event of a conflict between one or more provisions of this Agreement and one or more provisions of the Plan, the provisions of

17.

Administrator Authority.  The Administrator will have the power to interpret the Plan and this Agreement and to adopt such rules for the administration, interpretation and application of the Plan as are consistent

therewith and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any Market Stock Units have vested).  All actions taken and all interpretations and determinations made by the
Administrator in good faith will be final and binding upon Participant, the Company and all other interested persons.  No member of the Administrator will be personally liable for any action, determination or interpretation made in good
faith with respect to the Plan or this Agreement.

18.

Electronic Delivery.  The Company may, in its sole discretion, decide to deliver any documents related to Market Stock Units awarded under the Plan or future Market Stock Units that may be awarded under the Plan

by electronic means or request Participant’s consent to participate in the Plan by electronic means.  Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or
electronic system established and maintained by the Company or another third party designated by the Company.

19.

20.

 Captions.  Captions provided herein are for convenience only and are not to serve as a basis for interpretation or construction of this Agreement.

Agreement Severable.  In the event that any provision in this Agreement will be held invalid or unenforceable, such provision will be severable from, and such invalidity or unenforceability will not be construed to

have any effect on, the remaining provisions of this Agreement.

21.

Section 409A. Notwithstanding anything in the Plan or this Agreement to the contrary, if the vesting of the balance, or some lesser portion of the balance, of the Market Stock Units is accelerated in connection with

Participant’s termination as a Service Provider (provided that such termination is a “separation from service” within the meaning of Section 409A, as determined by the Company), other than due to death, and if (x) Participant is a
“specified employee” within the meaning of Section 409A at the time of such termination as a Service Provider and (y) the payment of such accelerated Market Stock Units will result in the imposition of additional tax under Section 409A
if paid to Participant on or within the six (6) month period following Participant’s termination as a Service Provider, then the payment of such accelerated Market Stock Units will not be made until the date six (6) months and one (1) day
following the date of Participant’s termination as a Service Provider, unless the Participant dies following his or her termination as a Service Provider, in which case, the Market Stock Units will be paid in Shares to the Participant’s estate
as soon as practicable following his or her death. It is the intent of this Agreement to comply with the requirements of Section 409A so that none of the Market Stock Units provided under this Agreement or Shares issuable thereunder will
be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to so comply. For purposes of this Agreement, “Section 409A” means Section 409A of the Code, and any proposed, temporary or
final Treasury Regulations and Internal Revenue Service guidance thereunder, as each may be amended from time to time.

22.

Governing Law.  This Agreement shall be governed by the laws of the State of California, without giving effect to the conflict of law principles thereof.  For purposes of litigating any dispute that arises under this

Award of Market Stock Units or this Agreement, the parties hereby submit to and consent to the jurisdiction of the State of California, and agree that such litigation shall be conducted in the courts of Santa Clara County, California, or the
federal courts for the United States for the Northern District of California, and no other courts, where this Award of Market Stock Units is made and/or to be performed.

By Participant’s acceptance of this Agreement, Participant represents that he or she is familiar with the terms and provisions of the Plan, and hereby accepts this Agreement subject to all of the terms and provisions

thereof.  Participant has reviewed the Plan and this Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Agreement and fully understands all provisions of this
Agreement.  Participant agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Plan or this Agreement.  Participant further agrees to notify
