CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K of SmileDirectClub, Inc. (“SmileDirectClub,” “Company,” “us,” “we,” or “our”) contains forward-looking statements. Any statements about our expectations, beliefs, plans, predictions, forecasts, objectives, assumptions, or future events or performance are not historical facts and may be forward-looking.

Although we believe that the expectations reflected in these forward-looking statements are reasonable, these statements are not guarantees of future performance and involve risks and uncertainties which are subject to change based on various important factors, some of which are beyond our control. For more information regarding these risks and uncertainties as well as certain additional risks that we face, refer to “Risk Factors” as well as the factors more fully described in “Management’s Discussion and Analysis of Financial Conditions and Results of Operations.” Among the factors that could cause our financial performance to differ materially from that suggested by the forward-looking statements are:

•our ability to effectively manage our growth;

PART I

Item 1. Business

Our Company

SmileDirectClub was founded on one simple belief: everyone deserves a smile they love.

We are an oral care company and the creator of the first medtech platform for teeth straightening. Through our cutting-edge teledentistry technology and vertically integrated model, we are revolutionizing the oral care industry, from clear aligner therapy to our affordable, premium oral care product line.

Our clear aligner treatment addresses the large and underserved global orthodontics market. We believe we are the leading player in this early but massive opportunity and that our aligner treatment can help over 90% of people with mild to moderate malocclusion achieve a better smile.

Our vertically integrated model enables us to solve critical problems around cost, convenience, and access to care. We offer professional-level service and high-quality clear aligners generally at a cost of $1,950, up to 60% less than traditional orthodontic solutions. We achieve these cost savings while maintaining high quality by removing the overhead cost of multiple in-person doctor visits and managing the entire member experience, all the way from marketing to aligner manufacturing, fulfillment, treatment by a member’s doctor, and monitoring through completion of their treatment, which is enabled by our proprietary teledentistry platform, SmileCheck. These efficiencies enable us to pass the cost savings directly to our members and allow doctors to focus on what matters most: providing convenient access to excellent clinical care. To further democratize access to care, we offer our members the option of paying the entire cost of their treatment upfront or enrolling in our financing program, SmilePay, a convenient monthly payment plan. We also accept insurance and as of December 31, 2021, are in-network with UnitedHealthcare, Aetna, Anthem, Cigna, Guardian, HUMANA, and MetLife, among others.

Our member journey starts with three convenient options: a member visits a dentist office within our expanding Partner Network, books an appointment to take a free, in-person 3D oral image at any of our permanent SmileShops or popup locations across the U.S., Puerto Rico, Canada, Australia, the U.K., and Ireland, or requests an easy to use, doctor-prescribed impression kit online, which we mail directly to the member’s door. Using the image or impression, along with the other information collected from the member, we create a draft custom treatment plan that demonstrates how the member’s teeth will move during treatment. Next, via SmileCheck, an appropriately licensed doctor within our network reviews the information collected from the member, and determines if the member is appropriate for treatment and if so finalizes and approves the member's treatment plan. If the member is a good candidate for clear aligners, the member has the opportunity to review a 3D rendering of how his or her teeth will move over time and, if the member decides to purchase, the licensed doctor issues the prescription for treatment and the manufacturing of the aligners. We then manufacture and ship the aligners directly to the member. The treating doctor monitors the member’s progress, requests additional information and/or clearances from the member, and communicates seamlessly with the member over the course of treatment through SmileCheck. Upon completion of treatment, a majority of our members purchase retainers every six months to prevent their teeth from relapsing to their original position. We also offer a growing suite of ancillary oral care products, such as whitening kits, toothbrushes, toothpaste, a water flosser, SmileSpa and a variety of other ancillary oral care products to maintain a perfect smile.

More About Our Member Journey

Through our member-centric platform, we have disrupted the traditional orthodontics industry, and in the process have helped over 1,500,000 members and growing. Our proprietary technology and platform offer consumers the ability to receive the same clinically safe and effective treatment but without the 3x markup.

3

Members start their journey by visiting our website, where they can learn about how our process works, read first-hand reviews from other members, and view before and after photos. Members then proceed with their journey through one of three convenient options:

•In person at a Partner Network location: A member visits a dentist office or books an appointment online to take a free, in-person 3D oral image.

•In person at a SmileShop: A member can use our website to easily book an appointment to take a free, in-person 3D oral image at any of our popup locations or permanent SmileShops across the U.S., Puerto Rico, Canada, Australia, the U.K., France, and Ireland. At the 30-minute appointment, one of our team members (“SmileGuides”) uses a handheld oral camera that takes approximately 6,000 photos per second to create a highly detailed digital map of the member’s smile.

•Remotely with an impression kit: A member can request an easy-to-use doctor prescribed impression kit online, which we mail directly to their door pursuant to the prescription of a licensed doctor. Our impression kits are simple to use and can typically be completed by a member within 30 minutes. The member then returns their completed impression in a prepaid shipping box so that the impression can be scanned and digitized by our affiliated dental lab.

Once completed, the image or impression is used to create a digital map of the member’s mouth, which our trained technicians use to create a draft custom treatment plan that contains the clinical protocols for how the member’s teeth will move during treatment. The treatment plan is then sent to an appropriately licensed doctor in our network. Within 48 hours, the doctor reviews the treatment plan, together with the member’s oral photos, dental and health history, and chief complaint, and, where appropriate, approves the member’s clinical information and treatment plan and prescribes custom-made clear aligners. The appropriately licensed dentist may also request additional information before making any determination where required by international or state law or otherwise desired by the dentist, or reject the patient for treatment using our teledentistry platform.

At this point in the journey, we offer our members two payment options to purchase the prescribed aligners: pay the full cost of treatment upfront or enroll in a convenient monthly payment plan that provides a flexible payment option to make our clear aligner treatment even more accessible (“SmilePay”). With a $250 down payment and an average monthly payment of only $89, SmilePay provides a more affordable option for those who cannot make the $1,950 full payment upfront.

Following a member’s purchase, we manufacture and ship the full set of custom-made clear aligners directly to the member. The average treatment lasts approximately four to six months. Once a member begins treatment, the member is required to upload photos and other information to SmileCheck at least every 60 days for their treating doctor to review and order any touch-up aligners, as needed. In addition, we offer 24/7 access to care and members can connect with their treating doctor at any point in the process through SmileCheck or we can facilitate communications with their treating doctor via other means if desired by the member or the treating doctor.

As a testament to our confidence in the quality and efficacy of our product, we offer a Lifetime Smile Guarantee. Our Lifetime Smile Guarantee ensures a full refund if a member is not satisfied for any reason within the first 30 days and a pro-rated refund, or additional aligners at no cost for further adjustment, if the member is not satisfied at any point later in the process. Upon completion of treatment, a majority of our members purchase retainers every six months to prevent their teeth from relapsing to their original position. As long as our members are compliant with treatment protocols, we will guarantee their smile for life. We also offer a growing suite of ancillary oral care products, such as whitening kits, toothbrushes, toothpaste, and other ancillary oral care products to maintain a perfect smile.

Throughout our member journey, we are singularly focused on delivering an exceptional member experience. We manage every member touchpoint and communication, enabling us to continually refine and optimize the member experience.

Our Strengths

We believe our strengths will allow us to maintain and extend our position as a leading clear aligner provider. Below is a summary of our key strengths:

Mission-driven brand with positive member experience

Our mission is to democratize access to a smile each and every person loves, and we strive to create the best possible experience doing so. Our commitment to member experience has produced an average net promoter score of 55 since inception. More than 66% of our members surveyed are promoters of our SmileShop experience to friends and approximately 20% of our members today come through referrals. We believe we enjoy the largest reach and presence on social media relative to our competitors, with over 650,000 likes on Facebook and over 470,000 followers on Instagram as of December 31, 2021. Clear aligners are a highly considered purchase, and our scale and member satisfaction are important criteria that will enable us to maintain our position as the leading clear aligner provider.

Omni-channel presence with a large SmileShop and Partner Network footprint

With three options for members to start their journey, we empower members to choose how they would like to interact with us. If a member chooses to order a doctor prescribed impression kit, we will mail one directly to the member’s door. Alternatively, we have a network of 188 permanent SmileShops and approximately 60 popup locations monthly, as well as partnerships with over 650 dental practices in our Partner Network across the U.S., Puerto Rico, Canada, Australia, the U.K., France, and Ireland, which provides an in-person experience to members who prefer that channel.

Our SmileShops and popup locations give our members more convenient ways to access care. Furthermore, our SmileShops, popup locations, and Partner Network locations require little capital investment, with minimal upfront capital expenditure.

Exclusive licensed doctor network across all 50 U.S. states, Puerto Rico, Canada, Australia, the U.K., France, and Ireland

We have a network of approximately 250 orthodontists and general dentists across the U.S., Puerto Rico, Canada, Australia, the U.K., France, and Ireland, who are fully licensed across these jurisdictions to meet regulatory requirements, and we continue to successfully expand our doctor network to support our growth. In addition, we believe our domestic doctor network is sufficient to support our growth. The doctors in our network evaluate whether members are viable candidates for clear aligner therapy and if they move forward with treatment, they are responsible for evaluating our members’ progress throughout treatment and are available to answer any questions should members need additional assistance.

SmilePay captive financing increases accessibility and reduces purchasing friction

SmilePay is a key element to democratizing access to care and removing price as a limiting factor for our members. As of December 31, 2021, approximately 60% of our members have elected to purchase our clear aligners using SmilePay, which does not require a credit check. With SmilePay, a $250 down payment is required up front, which covers the cost of manufacturing the aligners. The remaining cost is financed over 24 months at an average monthly cost of $89 per month. For the years ended December 31, 2021 and 2020, we offered SmilePay at an APR of approximately 20% and 18%, respectively, which had an associated delinquency rate of approximately 9% of revenue for the years ended December 31, 2021 and 2020, respectively. We believe SmilePay, as a captive offering, reduces purchasing friction by removing the complex third-party financing process, resulting in higher member conversion and a better overall member experience.

Vertical integration powered by SmileCheck allows us to optimize every step of the member journey

We are the first clear aligner company to build a scalable, integrated technology platform and doctor network for teledentistry. We manage the entire end-to-end process in a member’s journey, from the moment a member visits the website all the way through aligner manufacturing, fulfillment, and treatment monitoring by a member’s doctor through completion

5

of his or her treatment. Our proprietary software platform, SmileCheck, supports rapid and efficient communication between our members and their treating doctors, and the clinical and customer care teams.

Managing the member journey from start to finish provides us with a comprehensive understanding of our members and enables us to provide personalized, data-driven insights. It also enables us to quickly test and pilot new solutions and rapidly implement changes to our platform in order to deliver the best outcome for our members and our business.

Our expertise in leveraging data and process engineering allows us to continually evolve how we interact with our members.

Our Growth Strategy

Our mission is to provide everyone with a smile they love. We accomplish this by democratizing access to more affordable and convenient orthodontic care. We believe there is significant opportunity to further grow our member base. We have helped over 1,500,000 members out of a worldwide opportunity of approximately 500 million members. We plan to grow by continuing to pursue the following key growth strategies:

Increase demand and conversion

Given that we have captured less than 1% of the total market opportunity, we plan to grow our member base by continuing to focus our marketing efforts on the approximately 85% of people globally who have some form of malocclusion.

Our process engineering expertise, along with our meticulous attention to each step of the member experience, enables us to continually improve conversion at each of the hundreds of touchpoints throughout the member journey. We have been able to accomplish these improvements in conversion through our CRM strategies, educational efforts, technology advancements, and data-driven insights.

We see significant opportunity to continue increasing overall demand for our products and improving conversion at every touchpoint across our member acquisition funnel.

Successfully target higher income customers

There are approximately 20 million annual world-wide case starts for traditional clear aligners and wires and brackets (“W&B”). We estimate that the average cost for these traditional cases is between $6,000 to $8,000, or approximately three times our offering at approximately $1,950. Given our relative price positioning in the market, we believe our growth has largely come from expanding the market by making teeth straightening more accessible to non-traditional, lower income consumers that would not typically be able to afford the $6,000 to $8,000 price of traditional teeth straightening offerings. We believe the higher income traditional consumer makes greater than $125,000 per year and presents a significant growth opportunity for us by successfully gaining share from traditional suppliers in the space.

Higher income consumers purchasing for Teens represents the largest market opportunity for our brand. Teens are approximately 75% of case starts annually, but currently make up only approximately 10% of SmileDirectClub members. We launched SmileDirectClub Teen as a result of this opportunity. Designed just for teens, this offering includes a more affordable and accessible alternative to metal braces or other aligner options, giving teens and parents the convenience of our telehealth platform, with 24/7 access to dental professionals, while still priced 60% less than traditional orthodontic products.

Creation of new aligner products and technology

In 2019, we launched our innovative Nighttime Clear Aligner product into the U.S. market and our international markets. This proprietary new product, which requires only 10 hours of nightly wear, enables us to expand our market to customers who are unwilling or unable to wear aligners for the 22-hour daily wear cycle typically required with traditional clear aligner therapy.

6

In 2021 we launched our Comfort Sense technology featuring our patented laser technology that precision-cuts our aligners for a smoother fit, which, combined with the variable thicknesses of the aligners and doctor-prescribed and monitored treatment plans that start with lighter movements to ease customers into treatment, all results with a more comfortable fit and treatment for our customers. We also launched our new treatment planning system, SmileOS, in 2021. This next generation proprietary treatment planning software enables our network of appropriately licensed doctors to treat more patients, more accurately predict tooth movements, and better visualize their patients’ treatments.

Expand reach through growth in the Professional Channel

In response to market demand and requests by dentists and orthodontists, we have focused and grown our collaborative model with the dentists and orthodontists in our existing network of affiliated dentists (“Partner Network”). The collaborative model enables patients who wish to start their member journey in a regular dentist office to do just that.  Their regular dentist’s office will collect the same patient information that our SmileShops and popup locations collect for subsequent review and assessment by one of the dentists or orthodontists in our affiliated network. We have also extended this collaborative model to dentists and orthodontists outside of our affiliated network, and we expect to continue offering the collaborative model to dentists in the U.S. Currently we have more than 650 affiliated dental practices in our Partner Network with 1,200 more in the pipeline for onboarding.

The Partner Network model not only expands on our commitment to customer convenience by allowing us to meet customers through the channel that makes sense for them but also allows us to improve our credibility with higher income customers. Higher income customers are more likely to seek a reference from a dental professional before deciding on a teeth straightening provider. Partner Network puts us directly in front of dental professionals allowing us to effectively educate and build credibility in the dental community, which deepens our foundation for future growth by improving our chances for success with higher income customers.

Retail partnerships and adjacent product expansions

Our business model introduces us to customers with a lifetime need for oral care. After treatment, our customers have a smile they are proud of and intent on maintaining. Because teeth are often prone to revert back to pre-treatment positioning, we offer our customers retainer subscription options. In addition, customers after treatment are more interested in overall oral care and looking for products such as whitening and cleaning that help them protect the investment they made in their smile through treatment. These highly complementary offerings allow us to build a recurring revenue stream that furthers the investments we are making in our customers on the front end by expanding their lifetime value to us as a customer.

Oral care is a highly competitive space, so we remain focused on developing our brand of innovative products to drive awareness, trial and repeat purchases through a diverse portfolio of differentiated oral care products. For instance, we are developing products to further penetrate the oral care market and have already launched numerous ancillary products such as retainers, toothbrushes, toothpaste, water flosser, SmileSpa, lip balm, MoveMints, BrightOn premium whitening, and an LED accelerator light to address our members’ oral care needs, along with many other oral care products. We believe that our growing suite of products will lengthen our relationship with our members and enhance our recurring stream of revenue.

In 2020 and 2021, we introduced a suite of affordable premium oral care products becoming the only clear aligner brand that offers consumers an end-to-end solution to keep teeth brighter, straighter and healthier with offerings in teeth whitening, electric brushes, and power flossing. Since launching the line, we have seen strong growth in the oral care segment, specifically the whitening category.

More recently in January 2022, we announced the launch of our Fast-Dissolving Whitening Strips. Our whitening strips compete directly with the largest platform in the whitening category. Clinical research has also shown this innovative product is more comfortable and effective in less time than other well-known competing brands in the whitening-strip category. In addition, we launched the first-to-market Stain Barrier pen that is a proactive treatment to help shield against staining beverages such as coffee, tea, and wine. Both launches are effectively furthering the brand’s reputation as an

7

innovative oral care provider with products that are designed to meet the customer’s needs.

As our brand continues to grow through innovative new product launches such as Fast-Dissolving Whitening Strips and Stain Barrier, we anticipate the customer relationships we have developed through oral care will transfer over to teeth straightening when the customer is ready to start their journey.

Leverage data science and technology

With over 1,500,000 members helped to date, we have one of the largest repositories of data in the oral care sector. Using this data and artificial intelligence, along with other technologies, we believe we can enhance our existing offerings, improve our manufacturing, and produce new products. We will leverage this same information and technology to enhance our products and to develop and introduce new products.

Expand Business Partnerships

We are party to standard in-network insurance coverage agreements with UnitedHealthcare, Aetna, Anthem, and MetLife, among others, to include coverage for our aligners on an in-network basis, which means our members who participate in these plans can obtain treatment at a lower out-of-pocket cost, after insurance coverage and negotiated discounts, and do not need to retroactively submit for reimbursement. These agreements have decreased the upfront cost to our members and further streamline the complete revenue cycle management process, from eligibility check to payment posting. We are currently negotiating with other large insurance companies for similar arrangements. In addition, we are currently negotiating other business partnerships, such as corporate SmileDays and corporate discount programs, among others.

Selectively pursue M&A opportunities

We may leverage our know-how and our platform’s expanding scale to selectively pursue acquisitions and are in discussions with several parties regarding these acquisitions. Our acquisition strategy is centered on acquiring technologies, products, and capabilities that are highly scalable and that are complementary to our business model.

Sales and Marketing

Our management team has substantial experience successfully marketing direct-to-consumer brands. We market our aligners and other products through an omni-channel approach supported by media mix modeling (MMM). Our marketing approach focuses on both offline activities, mainly television, and online digital marketing as well as campaigns directly targeted at the higher income customer market.

Treatment Plan Design and Aligner Manufacturing

We produce customized aligners based on a doctor’s review of a member’s dental and health history, chief complaint, photographs, and a 3D image of the member’s mouth resulting from receiving a digital scan or physical impression. To produce the customized aligners, we have developed a number of proprietary processes and technologies, including complex software solutions, laser, destructive and white light scanning techniques, stereolithography, 3D printing, and thermoforming. Our manufacturing is performed by Access Dental Lab, LLC, our wholly owned subsidiary.

Treatment plan design

Members have the option of booking an appointment to take a free, in-person 3D oral image at any of our Partner Network locations, SmileShops or popup locations, where one of our SmileGuides uses a handheld oral camera that takes approximately 6,000 photos per second to create a highly detailed digital map of the member’s smile, or requesting one of our easy-to-use impression kits online and returning their completed impression to our manufacturing facility, or visit a dentist participating in our collaborative model network to obtain a free, 3D oral scan or have physical impressions taken.

8

Our trained technicians then use the image or impression to create a draft custom treatment plan that contains the clinical protocols for how the member’s teeth will move during treatment. The rules that govern the clinical protocols are contained within our proprietary software that is specifically designed for our aligners. Lastly, prior to a locally licensed doctor in our network reviewing the case, all treatment plans go through a quality review with our doctors in Costa Rica.

Initial treatment plan design is conducted primarily at our facilities in San Jose, Costa Rica. Costa Rica’s status as one of the Americas’ leading nations for dental education and expertise enables us to recruit and employ highly qualified personnel in our treatment plan setup facilities.

After the treatment plan has been designed, a doctor licensed in the member’s state, or appropriate international jurisdiction, as the case may be, reviews the member’s oral photos, dental and health history, chief complaint, treatment plan, and, when required or deemed appropriate by the treating doctor, x-rays or other bone imaging suitable for orthodontia, to make an independent initial determination of the member’s suitability for clear aligner treatment. The treating doctor can then approve the treatment plan and prescribe the member’s clear aligners, request additional information from the member or clearances from the member’s dentist prior to making a determination on treatment, decline the member as a candidate for clear aligners, typically due to an oral health concern or the complexity of the case, or return it to the treatment plan setup team for specified adjustments prior to final approval.

Lastly, we have an extensive team responsible for reviewing every aligner that is manufactured prior to shipping and maintaining compliance with FDA and other applicable regulations to help ensure a high level of quality in our final product.

Aligner manufacturing

Our aligners are manufactured at our facilities in Antioch, Tennessee, where we employ approximately 700 team members. Every order is custom made, and we believe the complexity inherent in producing our highly customized aligners in large volumes is a barrier to potential competitors. We continue to make significant advances in manufacturing automation to improve quality and reduce cost, and we expect to automate additional manufacturing functions in the future.

We have agreements with the suppliers of the raw materials needed to manufacture our aligners and for the putty used in our at-home impression kits. We also rely on a third party to assemble and distribute our at-home impression kits. There are alternative suppliers available for all raw materials we require and our supply agreements specifically provide for our ability to purchase from these alternate sources if our preferred suppliers are not capable of meeting demand. We also have the ability to secure additional manufacturing from other sources, if required.

Doctor Network

We have a proprietary network of approximately 250 appropriately licensed orthodontists and general dentists across the U.S., Puerto Rico, Canada, Australia, France, the U.K., and Ireland. We recruit doctors with the appropriate licenses across jurisdictions to meet regulatory requirements and continue to expand our network to support our growth. In addition to being in good standing in the jurisdictions where each doctor is licensed to practice dentistry, doctors in our network must have at least 4 years’ experience in treating patients with clear aligner therapy in a traditional bricks and mortar setting. Doctors in our network review member records, evaluate candidacy for treatment, review, refine and approve treatment plans, prescribe clear aligners, communicate with members, review case progress, order any necessary treatment plan modifications, and are available to answer any questions should members need additional assistance. As we expand, we will expand our doctor network with appropriately licensed professionals.

Comprehensive Member Care

We provide comprehensive 24/7 customer care to our members through a variety of communication channels, including our website, video, phone, chat, email and social media as well as self-guided resources such as knowledge-based and how-to videos and articles on our website. We have a dedicated team of approximately 400 customer care team members in Nashville and Costa Rica, including general customer care team members, an advanced customer care team to address more

complex questions, and a clinical customer care team of certified dental professionals available to answer clinical questions. In addition, each member’s treating doctor is available to answer clinical questions as needed or when requested by the member or the treating doctor.

We believe that providing timely, responsive support and educational content to our members helps foster an ongoing engagement that builds loyalty to our brand and also enables us to understand member needs as they evolve. Our member community serves as an efficient and engaging platform through which we can deliver customer care and receive feedback from members. We gather and analyze user feedback from all platforms to help inform our design and engineering teams on future enhancements to our products and services. As our member base grows in new geographies, we will continue to focus on building a scalable support infrastructure that enables our members to engage with us through the channel that is most convenient and efficient for their needs.

SmileCheck

All of our member data is stored in our SmileCheck platform, a proprietary central data repository for all medical records, business transactions, and member communications. SmileCheck supports rapid uniform access to, and use of, member information across any internet-connected device.

From a member’s standpoint, SmileCheck powers a user-friendly online portal that allows for easy remote access to treatment plan information, SmilePay account details and communications on a convenient, integrated platform that can be accessed whenever and wherever members choose. SmileCheck facilitates real-time, remote sharing of treatment data between our members and their treating doctors, thus avoiding inconvenient, in-person doctor visits. In lieu of in-person visits, members are required to upload dental photos to SmileCheck at least every 60 days, in addition to other information, so that their treating doctor may review their progress.

Our doctor network also uses SmileCheck for case assignment and management. Our software automatically connects each member’s case to a doctor licensed in that member’s state, or appropriate international jurisdiction, as the case may be. Once a case is accepted by the appropriate doctor, that doctor is able to study the members’ records, request additional information and/or clearances, review, refine, and approve treatment plans, prescribe clear aligners, communicate with members, assess case progress and order any necessary treatment plan modifications, all via SmileCheck.

Research and Development

We have a research and development team with medical device development, dental/orthodontic, data science and other innovation focused backgrounds. Our research and development efforts are primarily focused on new product development for orthodontic and ancillary oral care products as well as data science and manufacturing automation.

Intellectual Property

We have 32 issued U.S. patents, seven allowed U.S. patent applications, and numerous pending U.S. and global patent applications. These patents and applications cover critical aspects of our process, including impression kit design, the SmileShop process, our Partner Network model, other systems, methods, and devices that facilitate the capture of customer images and data, certain key aspects of SmileOS, manufacturing automation and process, and our SmileCheck software, and they also cover our innovative oral care product offerings. Our issued U.S. patents expire from 2037 to 2039.

We have 49 issued U.S. trademark registrations, and over 15 pending U.S. trademark applications. We also own over 300 issued foreign trademark registrations in countries such as Australia, Brazil, Canada, China, France, Germany, India, Ireland, Italy, Japan, Mexico, New Zealand, Singapore, Spain, South Korea, Switzerland, Taiwan, and the United Kingdom, and have over 100 additional foreign trademark applications currently pending in various jurisdictions worldwide. Collectively, our global trademark filings cover our SMILE DIRECT CLUB® house marks for use in connection with a wide variety of goods and services related to our business, as well secondary marks (e.g., BRIGHT ON®, SMILECHECK® and SMILESHOP®) and slogans.

10

We continue to pursue further intellectual property protection through U.S. and non-U.S. patent applications, trademark applications, and non-disclosure and non-compete agreements. We also seek to protect our software, documentation and other written materials under trade secret and copyright laws. There can be no assurance that patents will be issued as a result of any patent application or that patents that have been issued to us or may issue in the future will be found to be valid and enforceable and sufficient to protect our technology or products. Information regarding risks associated with failing to protect 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.”

Seasonality

Our business does not experience material seasonality fluctuations in the results of our operations and cash flow needs throughout the year. However, we do increase our marketing spend at certain periods of the year, such as the first quarter of the calendar year, when members typically have a higher focus on aesthetics, and we experience corresponding increases in website traffic and SmileShop bookings as a result of these increased marketing efforts.

Competition

We compete with a handful of smaller companies that collectively have limited market share in the clear aligner industry, including Candid Co., Byte (Dentsply), and SnapCorrect. With the introduction of our collaborative and wholesale partner network, we also face competition from more well-established competitors in the traditional orthodontic industry, which requires in-person visits, such as Align Technology, Inc. We believe that the principal competitive factors and what makes us stand out in the market for orthodontic appliances include:

•Credibility: Each individual treatment plan is prescribed, directed, and managed by an appropriately licensed doctor who we require to have a minimum of four years of experience in clear aligner therapy in a traditional setting.

•Certainty: Delivering a new smile in as little as four months protected by our Lifetime Smile Guarantee.

•Comfort Sense: Our aligners are made using Comfort Sense TM technology, which utilizes soft, medium, and firm plastics to safely and gradually shift your teeth.

•Convenience: Offering a 22-hour daily wear aligner or our Nighttime Clear Aligner treatment plan to fit our members’ lifestyle with three ways to get started - from home, at a SmileShop or popup location, or with a partner network dentist.

•Cost: Offering the smile of your dreams without the 3x markup with an easy one-time payment or convenient monthly payments.

We believe that these differentiating factors allows us to compete favorably with respect to each of these factors.

Regulatory Matters

Our aligners, retainers, whitening products, and impression kits are considered medical devices and, accordingly, are subject to rigorous regulation by government agencies in the U.S. and other countries in which we sell our products. Compliance with these rigorous regulations will affect capital expenditures, earnings and the competitive position of the Company. These regulations vary from country to country but cover, among other things, the following activities with respect to medical devices:

•design, development and manufacturing;

•testing, labeling, content and language of instructions for use and storage;

11

•product storage and safety;

•marketing, sales and distribution;

•pre-market clearance and approval;

•record keeping procedures;

•advertising and promotion;

•recalls and field safety corrective actions;

•post-market surveillance;

•post-market approval studies; and

•product import and export.

FDA regulation

In the U.S., numerous laws and regulations govern the processes by which medical devices are developed, manufactured, brought to market and marketed. These include the Federal Food, Drug, and Cosmetic Act (“FD&C Act”) and its implementing regulations issued by the U.S. Food and Drug Administration (the “FDA”), among others. Unless an exemption applies, each medical device commercially distributed in the United States requires FDA clearance of a 510(k) premarket notification (“510(k) clearance”), granting of a de novo request, or approval of an application for premarket approval (“PMA’’). In general, under the FD&C Act, medical devices are classified in one of three classes on the basis of the controls necessary to reasonably assure their safety and effectiveness. A medical device’s classification determines the level of FDA review and approval to which the device is subject before it can be marketed to consumers:

•Class I devices, the lowest-risk FDA device classification, include devices with the lowest risk to the patient and are those for which safety and effectiveness can be assured by adherence to FDA’s medical device general controls, including labeling, establishment registration, device product listing, adverse event reporting, and, for some products, adherence to good manufacturing practices through FDA’s Quality System Regulations.

•Class II devices, moderate-risk devices, also require compliance with general controls and in some cases, special controls as deemed necessary by FDA to ensure the safety and effectiveness of the device. These special controls may include performance standards, particular labeling requirements, or post-market surveillance obligations. While most Class I devices are exempt from the 510(k) premarket notification requirement, typically a Class II device also requires pre-market review and 510(k) clearance as well as adherence to the Quality System Regulations/good manufacturing practices for devices.

•Class III devices, high-risk devices that are often implantable or life-sustaining, also require compliance with the medical device general controls and Quality System Regulations, and generally must be approved by FDA before entering the market through a PMA application. Approved PMAs can include post-approval conditions and post-market surveillance requirements, analogous to some of the special controls that may be imposed on Class II devices.

Our manufacturing quality system is required to be in compliance with the Quality System Regulations enforced by FDA and similar regulations enforced by other worldwide regulatory authorities. FDA’s Quality System Regulations require manufacturers to follow stringent design, testing, process control, documentation, and other quality assurance procedures.

12

Our retainers are Class I devices, which may be marketed in the U.S. without premarket clearance or approval by FDA and are subject to general controls, including labeling, establishment registration, and adherence to good manufacturing practices through FDA’s Quality System Regulations.

We market our clear aligner products in the U.S. pursuant to 510(k) clearance as they are a Class II medical device. The manufacture, marketing and distribution of our aligners and other medical device products are subject to continuing regulation and enforcement by FDA and other government authorities, which includes routine FDA inspections of our facilities to determine compliance with facility registration requirements, product listing requirements, medical device reporting regulations, and Quality System Regulations, among others. If FDA finds that we have failed to comply with Quality System Regulations or other legal or regulatory requirements, it or other government agencies may institute a wide variety of enforcement actions against us, ranging from Warning Letters to more severe sanctions, including but not limited to financial penalties, withdrawal of 510(k) clearances already granted, and criminal prosecution. We have passed our International Organization for Standardization (“ISO”) and Medical Device Single Audit Program (“MDSAP”) certification process and have added the U.S. to our ISO/MDSAP certification. We were successful in passing our audit to renew our MDSAP certification in February of 2021.

The 510(k) process

Under the 510(k) process, the manufacturer must submit to FDA a premarket notification demonstrating that the device is “substantially equivalent” to either a device that was legally marketed prior to May 28, 1976, the date upon which the Medical Device Amendments of 1976 were enacted, and for which a PMA is not required, a device that has been reclassified from Class III to Class II or Class I, or another commercially available device that was cleared through the 510(k) process. To be “substantially equivalent,” the proposed device must have the same intended use as the predicate device, and either have the same technological characteristics as the predicate device or have different technological characteristics and not raise different questions of safety or effectiveness than the predicate device. Clinical data is sometimes required to support substantial equivalence.

After a 510(k) premarket notification is submitted, FDA determines whether to accept it for substantive review. If it lacks necessary information for substantive review, FDA will refuse to accept the 510(k) notification. If it is accepted for filing, FDA begins a substantive review. By statute, FDA is required to complete its review of a 510(k) notification within 90 days of receiving the 510(k) notification. As a practical matter, clearance often takes longer, and clearance is never assured. FDA may require further information, including clinical data, to make a determination regarding substantial equivalence, which may significantly prolong the review process. If FDA agrees that the device is substantially equivalent to a predicate device currently on the market, it will grant 510(k) clearance to commercially market the device.

Post-market regulation

After a device is cleared or approved for marketing, numerous and extensive regulatory requirements may continue to apply. These include but are not limited to:

•annual and updated establishment registration and device listing with FDA;

•Quality System Regulation requirements, which require manufacturers to follow stringent quality assurance procedures during all aspects of the design and manufacturing process;

•restrictions on sale, distribution, or use of a device;

•labeling, advertising, promotion, and marketing regulations, which require that promotion is truthful, not misleading, and provide adequate directions for use and that all claims are substantiated, and also prohibit the promotion of products for unapproved or “off-label” uses and impose other restrictions on labeling;

13

•clearance or approval of product modifications to legally marketed devices that could significantly affect safety or effectiveness or that would constitute a major change in intended use;

•medical device reporting regulations, which require that a manufacturer report to FDA if a device it markets may have caused or contributed to a death or serious injury, or has malfunctioned and the device or a similar device that it markets would be likely to cause or contribute to a death or serious injury if the malfunction were to recur;

•correction, removal, and recall reporting regulations, and FDA’s recall authority;

•complying with the federal law and regulations requiring Unique Device Identifiers on devices; and

•post-market surveillance activities and regulations, which apply when deemed by FDA to be necessary to protect the public health or to provide additional safety and effectiveness data for the device.

FDA has broad regulatory compliance and enforcement powers. If FDA determines that we failed to comply with applicable regulatory requirements, it can take a variety of compliance or enforcement actions, which may result in any of the following sanctions:

•warning letters, untitled letters, fines, injunctions, consent decrees, and civil penalties;

•recalls, withdrawals, or administrative detention, or seizure of our products;

•operating restrictions or partial suspension or total shutdown of production;

•refusing or delaying requests for 510(k) marketing clearance or PMA approvals of new products or modified products;

•withdrawing 510(k) clearances or PMA approvals that have already been granted;

•refusal to grant export or import approvals for our products; or

•criminal prosecution.

International regulation

The Canadian Food and Drugs Act, and the Medical Device Regulations issued thereunder, provide for regulation by Health Canada of the manufacture, labeling, packaging, distribution, sale, and advertisement of medical devices. Our aligners are regulated as a Class II medical device under the Canadian Medical Device Regulations, which require, among other things, that Class II medical device manufacturers selling medical devices hold a medical device license and file various reports. We received our Canadian ISO/MDSAP certification in March 2019. In light of our ISO/MDSAP certification, we believe that we are in substantial compliance with applicable Canadian regulations and do not anticipate having to make any material expenditures as a result of Health Canada or other currently applicable regulatory requirements. Under Canadian regulation, manufacturing facilities are subject to periodic inspections by regulatory authorities and must comply with device safety and effectiveness requirements as required by the Medical Devices Regulations and Health Canada. To that end, we have implemented controls and procedures intended to ensure that our Access Dental Lab Quality System meets FDA’s and Health Canada’s requirements. We passed our audit to renew our MDSAP certification in February 2021.

In the U.K. and in the European Economic Area (“EEA”), our aligners and retainers are considered Class II custom made medical devices and are not required to have a CE mark certification acknowledging conformity with health and safety protection standards for sales of those products into the U.K. and the EEA. We have a CE mark for sales of our impression kits into the U.K. and EEA.

14

On April 5, 2017, the European Parliament passed the Medical Devices Regulation (Regulation 2017/745), which repeals and replaces the EU Medical Device Directive and became effective on May 26, 2021. The Medical Devices Regulation, among other things, is intended to establish a uniform, transparent, predictable, and sustainable regulatory framework across the EEA for medical devices and ensure a high level of safety and health while supporting innovation. It is possible under the new Medical Devices Regulation that our aligners could be deemed mass-produced rather than custom-made devices in which event we would need to apply for a CE mark for our aligners. Once applicable, the new regulations will, among other things:

•strengthen the rules on placing devices on the market and reinforce surveillance once they are available;

•establish explicit provisions on manufacturers’ responsibilities for the follow-up of the quality, performance, and safety of devices placed on the market;

•improve the traceability of medical devices throughout the supply chain to the end-user or patient through a unique identification number;

•set up a central database to provide patients, healthcare professionals, and the public with comprehensive information on products available in the E.U.; and

•strengthen rules for the assessment of certain high-risk devices, such as implants, which may have to undergo an additional check by experts before they are placed on the market.

In Australia, our retainers and aligners are considered custom-made medical devices and are exempt from inclusion in the Australian Register of Therapeutic Goods (‘‘ARTG”). The ARTG has recently issued new guidance on Personalised Medical Devices pursuant to which most of the custom-made devices will become patient-matched medical devices, requiring full TGA registration and inclusion on ARTG listing by January 1, 2024. As a result, we will proceed with such full registration and inclusion. Impression kits are considered Class I devices in Australia and New Zealand, and we are registered and listed with these countries to ship impression kits to our members there.

Quality System Regulations

Our manufacturing quality system is required to be in compliance with the Quality System Regulations enforced by FDA and similar regulations enforced by other worldwide regulatory authorities. FDA’s Quality System Regulations require manufacturers to follow stringent design, testing, process control, documentation, and other quality assurance procedures. If FDA finds that we have failed to comply with Quality System Regulations or other legal or regulatory requirements, it or other government agencies may institute a wide variety of enforcement actions against us, ranging from Warning Letters to more severe sanctions, including but not limited to financial penalties, withdrawal of 510(k) clearances already granted, and criminal prosecution. In addition, under Canadian regulation, manufacturing facilities are subject to periodic inspections by regulatory authorities and must comply with device safety and effectiveness requirements as required by the Medical Devices Regulations and Health Canada. To that end, we have implemented controls and procedures intended to ensure that our Access Dental Lab Quality System meets FDA’s and Health Canada’s requirements. We have an extensive Quality Assurance team at Access Dental Lab.

State professional regulation

Our ability to conduct business in each state is dependent in part upon that particular state’s treatment of remote healthcare delivery under such state’s laws, rules and policies governing the practice of dentistry, which are subject to changing political, regulatory and other influences. Orthodontists and dentists who provide professional services to a patient via teledentistry must, in most instances, hold a valid license to practice or to provide treatment in the state in which the patient is located. In addition, certain states require an orthodontist or dentist providing teledentistry services to be physically located in the same state as the patient. Failure to comply with these laws and regulations can give rise to civil or criminal penalties.

15

We have been successful in working with several state dental boards in creating teledentistry rules and regulations which support our model. In addition, more than 20 state dental boards have affirmatively rejected complaints filed by certain trade associations that we are engaged in the corporate practice of dentistry or are otherwise violating state regulations regarding the practice of dentistry. However, two state dental boards established rules or interpreted existing rules in a manner that purports to limit or restrict our ability to conduct our business as currently conducted. The Georgia Board of Dentistry passed a rule that requires a licensed dentist to be present when 3D oral images are taken by a dental assistant, and the Board of Dental Examiners of Alabama has interpreted existing rules to require “direct supervision” (meaning a dentist must be physically present somewhere in the building) for the taking of a digital image. In both Georgia and Alabama, we filed lawsuits in Federal court against the dental boards and their individual members alleging, among other things, violations of the Sherman Act, interfering with our business model. The Georgia Board of Dentistry has voluntarily agreed not to take any action against us pending a final resolution of the matter. In Alabama, we have obtained a Temporary Restraining Order precluding the Board of Dental Examiners from taking any action against us until a final disposition of the matter has occurred. Both the Alabama and Georgia courts upheld our ability to move forward against individual dental board members, in their official capacity. Both the Alabama and Georgia matters were then sent to the 11th Circuit Court of Appeals as a result of the dental boards in both states appealing the lower court’s decisions. Oral argument before the 11th Circuit Court of Appeals occurred in the Georgia matter on May 20, 2020 and in the Alabama matter on July 8, 2020. The FTC and DOJ participated in oral arguments in support of the Company. The DOJ’s antitrust chief presented in the Alabama matter. On August 11, 2020, the 11th Circuit Court of Appeals affirmed the Georgia district court’s denial of the board members’ motion to dismiss. On December 8, 2020, the 11th Circuit Court of Appeals voted to have a rehearing en banc. The FTC and DOJ filed an amicus brief and participated in oral argument that was held on February 23, 2021. On July 20, 2021 the 11th Circuit Court of Appeals ruled in the Company’s favor, finding that the Georgia Dental Board did not have an interlocutory right of appeal and therefore denied the Georgia Board’s appeal. On July 29, 2021, the 11th Circuit Court of Appeals also denied the Alabama Dental Board’s appeal. Both cases were remanded to the respective District Courts to proceed accordingly into the discovery phase. On August 17, 2021, the Alabama Dental Board and the Company entered into a tentative settlement agreement, subject to the FTC’s proposed Consent Order being entered into by the Board, precluding the Alabama Dental Board from engaging in conduct intended to preclude teledentistry in the State of Alabama or to preclude dentists and orthodontists from using the Company’s teledentistry platform to treat patients. On December 22, 2021, the Consent Order was finalized and the District Court in Alabama thereafter entered its order approving the joint motion for dismissal of the lawsuit per the terms of the settlement reached between the parties. In October 2019, we also filed a lawsuit against the California Dental Board, its members and one of its investigators for engaging in anticompetitive and harassing conduct. The California Dental Board filed a motion to dismiss and the District Court granted that Motion. We appealed the lower court’s decision and the Federal Trade Commission and the Department of Justice, as well as the Pacific Legal Foundation, all filed amicus briefs on our behalf. Oral argument was held on July 26, 2021 with the FTC and DOJ arguing in support of the Company at oral argument as well. The appellate court has not yet issued its ruling. In New Jersey, the Dental Association filed a lawsuit against us alleging that we are engaging in the illegal corporate practice of dentistry, without the support or inclusion of the New Jersey Dental Board as a party. In January 2020, the New Jersey court ruled in our favor, granting our motion for summary judgement. The New Jersey Dental Board appealed that ruling and the ruling of the lower court was affirmed by the Appellate Division on June 11, 2021. The Board filed a Notice of Petition for Certification with the Supreme Court of New Jersey on June 28, 2021. No decision on whether to accept the Petition and allow an appeal has been rendered. In addition, a national orthodontic association has met with various dental boards across the country in an effort to advocate for new rules and regulations that could have the effect of interfering with our business model. In October 2019, California passed a law requiring doctors using telehealth to prescribe clear aligner therapy to review a patient’s most recent x-ray or other bone imaging suitable for orthodontia. This law went into effect on January 1, 2020 but has not had any material impact on our operations. To date, none of these efforts have resulted in rules and regulations being passed that interfere with our business model in a material way, and we have engaged lobbyists to assist in educating policy makers about our positions. Legislation has been introduced in a handful of states mirroring the recent law in California or to require mandatory in person office visits or the taking and review of radiographs. To date none of these laws have been passed. Legislation has also been introduced and passed in more than 30 states specifically supporting and promoting telehealth and/or teledentistry, including but not limited to requiring insurance companies to pay for such services. We continually monitor these proposed laws and other legal and regulatory developments to understand their potential impact on our operations.

16

DSO regulation

We are engaged by a network of professional corporations (“PCs”) and their affiliated doctors to provide a suite of non-clinical administrative support services, including access to and use of SmileCheck, as a dental support organization, or DSO. As a result, we are required to register in those states that require registrations of DSOs, which currently include Nevada, Kansas, and Texas.

The doctors affiliated with our network of PCs are licensed to practice dentistry in their respective states and are engaged as employees or independent contractors of these PCs. These PCs are owned by independent doctors and are registered to engage in business in their respective states. It is through these PCs that the clinical services for clear aligner therapy are rendered to our members. We enter into a suite of agreements with each of the PCs to provide its DSO services. In addition, we are also a supplier of the clear aligner products to these PCs and enter into a Supply Agreement with each of the PCs accordingly. The District Court in New Jersey ruled that this structure and suite of agreements comply with the laws of the state of New Jersey precluding the corporate practice of dentistry.

Consumer credit compliance

Our SmilePay program subjects us to complex consumer financial protection laws and regulations, among others. We must comply with all applicable U.S. federal and state regulatory regimes, including but not limited to those governing consumer retail installment credit transactions. Certain U.S. federal and state laws generally regulate the rate or amount of finance charges and fees and require certain disclosures for consumer finance transactions. In particular, we may be subject to laws such as:

•state laws and regulations that impose requirements related to credit disclosures and terms, credit discrimination, credit reporting, debt servicing, and collection;

•the Truth in Lending Act and Regulation Z promulgated thereunder, and similar state laws, which require certain disclosures to customers regarding the terms and conditions of their transactions;

•Section 5 of the Federal Trade Commission Act, which prohibits unfair and deceptive acts or practices in or affecting commerce, Section 1031 of the Dodd-Frank Consumer Financial Protection Act, which prohibits unfair, deceptive, or abusive acts or practices in connection with any consumer financial product or service, and similar state laws that prohibit unfair or deceptive acts or practices;

•the Equal Credit Opportunity Act and Regulation B promulgated thereunder and state non-discrimination laws, which generally prohibit creditors from discriminating against credit applicants on the basis of, among other things, race, color, sex, age, religion, national origin, marital status, the fact that all or part of the applicant’s income derives from any public assistance program, or the fact that the applicant has in good faith exercised any right under the federal Consumer Credit Protection Act;

•the Fair Credit Reporting Act as amended by the Fair and Accurate Credit Transactions Act, and similar state laws, which promote the accuracy, fairness, and privacy of information in the files of consumer reporting agencies;

•the Fair Debt Collection Practices Act and similar state, and local debt collection laws, which provide guidelines and limitations on the conduct of debt collectors and creditors in connection with the collection of consumer debts;

•Title V of the Gramm-Leach-Bliley Act and similar state privacy laws, which include limitations on financial institutions’ disclosure of nonpublic personal information about a consumer to nonaffiliated third parties, in certain circumstances require financial institutions to limit the use and further disclosure of nonpublic personal information by nonaffiliated third parties to whom they disclose such information, and require financial institutions to disclose certain privacy policies and practices with respect to information sharing with affiliated and nonaffiliated entities as well as to safeguard personal customer information, and other privacy laws and regulations;

17

•the Bankruptcy Code and similar state insolvency laws, which limit the extent to which creditors may seek to enforce debts against parties who have filed for protection or relief from claims of creditors;

•the Servicemembers Civil Relief Act and similar state laws, which allow military members and certain dependents to suspend or postpone certain civil obligations, as well as limit applicable rates, so that the military member can devote his or her full attention to military duties;

•the Electronic Fund Transfer Act and Regulation E promulgated thereunder, which provide disclosure requirements, guidelines, and restrictions on the electronic transfer of funds from consumers’ deposit accounts;

•the Electronic Signatures in Global and National Commerce Act and similar state laws, particularly the Uniform Electronic Transactions Act, which authorize the creation of legally binding and enforceable agreements utilizing electronic records and signatures and, with consumer consent, permits required disclosures to be provided electronically; and

•the Bank Secrecy Act, which relates to compliance with anti-money laundering, customer due diligence, and record-keeping policies and procedures.

Other U.S. federal and state laws

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, reimbursement for our products and services, the operation of our facilities, and the distribution of our products. Initiatives sponsored by government agencies, legislative bodies, and the private sector regarding these matters, including efforts 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 and other measures on our future business.

We contract with orthodontists, dentists, or professional corporations to deliver our products and services to their patients. These contractual relationships are subject to various state laws that prohibit the practice of dentistry by lay entities or persons and are intended to prevent unlicensed persons from interfering with or influencing the orthodontist’s or dentist’s professional judgment. In addition, laws in various states also generally prohibit the sharing of professional services income with nonprofessional or business interests. Activities other than those directly related to the delivery of healthcare may be considered an element of the practice of dentistry in many states. Under the corporate practice of dentistry restrictions of certain states, non-clinical decisions and activities may implicate the restrictions on the corporate practice of dentistry. Further, certain states have requirements for Dental Support Organizations, or DSOs, such as us. We have registered as a DSO in all states in which we are required to do so. We continually monitor state requirements as to what constitutes the practice of dentistry and take steps to ensure that the orthodontists and dentists who utilize our services and teledentistry platform handle all clinical aspects of their patients’ care to ensure we do not violate those laws and regulations.

As a participant in the health care industry we are subject to extensive and frequently changing regulation under many other 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 network of orthodontists and general dentists is also subject to a wide variety of laws and regulations that could affect the nature and scope of their relationships with us. Laws regulating medical device manufacturers and health care providers cover a broad array of subjects.

Several states have fraud and abuse and consumer protection laws that apply to healthcare items or services reimbursed by any third party payor, including commercial insurers, not just those reimbursed by a federally funded healthcare program, or apply regardless of payor. The scope of these laws and the interpretations of them vary from state to state and are enforced by state courts and regulatory authorities, each with broad discretion. A determination of liability under such laws could result in fines and penalties and restrictions on our ability to operate in these jurisdictions.

18

Health information privacy and security laws

There are numerous U.S. federal and state laws and regulations related to the privacy and security of personally identifiable information (“PII”), including health information. Among others, the federal Health Insurance Portability and Accountability Act of 1996, as amended by Health Information Technology for Economic and Clinical Health Act (“HITECH”), and their implementing regulations, which we collectively refer to as HIPAA, establish privacy and security standards that limit the use and disclosure of Protected Health Information (“PHI”) and require covered entities and business associates to implement administrative, physical, and technical safeguards to ensure the confidentiality, integrity, and availability of individually identifiable health information in electronic form, among other requirements. We are regulated as a covered entity under HIPAA.

Violations of HIPAA may result in civil and criminal penalties. We must also comply with HIPAA’s breach notification rule which requires notification to affected individuals and the Secretary of Health and Human Services (“HHS”), and in certain cases to media outlets, in the case of a breach of unsecured PHI. The regulations also require business associates of covered entities to notify the covered entity of breaches by the business associate.

State attorneys general also have the right to prosecute HIPAA violations committed against residents of their states, and HIPAA standards have been used as the basis for the duty of care in state civil suits, such as those for negligence or recklessness in misusing personal information. In addition, HIPAA mandates that HHS conduct periodic compliance audits of HIPAA covered entities and their business associates for compliance.

Many states in which we operate and in which our customers reside also have laws that protect the privacy and security of sensitive and personal information, including health information. These laws may be similar to or even more protective than HIPAA and other federal privacy laws. For example, the laws of the State of California, in which we operate, are more restrictive than HIPAA. Where state laws are more protective than HIPAA, we must comply with the state laws we are subject to, in addition to HIPAA. California passed the California Consumer Privacy Act or CCPA on June 28, 2018, which went into effect January 1, 2020. While information we maintain that is covered by HIPAA may be exempt from the CCPA, other records and information we maintain on our members may be subject to the CCPA. In certain cases, it may be necessary to modify our planned operations and procedures to comply with these more stringent state laws. Not only may some of these state laws impose fines and penalties upon violators, but also some, unlike HIPAA, may afford private rights of action to individuals who believe their personal information has been misused. In addition, state and federal privacy laws subject to frequent change.

In addition to HIPAA and state health information privacy laws, we may be subject to other state and federal privacy laws, including laws that prohibit unfair privacy and security practices and deceptive statements about privacy and security, laws that place specific requirements on certain types of activities, such as data security and texting, and laws requiring holders of personal information to maintain safeguards and to take certain actions in response to a data breach.

Foreign data protection, privacy, and other laws and regulations are often more restrictive than those in the U.S. The E.U., for example, traditionally has imposed stricter obligations under its laws and regulations relating to privacy, data protection and consumer protection than the U.S. In May 2018, the General Data Protection Regulation (“GDPR”), which governs data practices and privacy in the E.U., became effective and provides a basis for the data protection laws of the individual member states. The E.U.’s GDPR requires companies to meet stringent requirements regarding the handling of personal data of individuals in the E.U. These more stringent requirements include expanded disclosures to inform individuals about how we may use their personal data, increased controls on profiling individuals, and increased rights for individuals to access, control and delete their personal data. In addition, there are mandatory data breach notification requirements. The law also includes significant penalties for non-compliance, which may result in monetary penalties of up to 20 million Euros or 4% of a group’s worldwide turnover, whichever is higher. GDPR and other similar regulations require companies to give specific types of notice and informed consent is required for the placement of a cookie or similar technologies on a user’s device for online tracking for behavioral advertising and other purposes and for direct electronic marketing, and the GDPR also imposes additional conditions in order to satisfy such consent, such as a prohibition on pre-

19

checked consents. It remains unclear how the U.K. data protection laws or regulations will develop in the medium to longer term and how data transfer to the U.K. from the E.U. will be regulated.

We are subject to Personal Information Protection and Electronic Documents Act (“PIPEDA”) and similar provincial laws in Canada. PIPEDA is the federal privacy law for private-sector organizations. It sets out the ground rules for how businesses must handle personal information in the course of commercial activity. Under PIPEDA, we must obtain an individual’s consent when we collect, use or disclose that individual’s personal information. Individuals have the right to access and challenge the accuracy of their personal information held by an organization, and personal information may only be used for the purposes for which it was collected. If an organization intends to use personal information for another purpose, it must again obtain that individual’s consent. Failure to comply with PIPEDA could result in significant fines and penalties or possible damage awards for the tort of public humiliation.

We are subject to the Australian Privacy Act of 1988 (“Privacy Act”), of which the Australian Government is conducting a review and updates to the law are actively under review. The Privacy Act regulates the private sector’s use of personal information, and also includes a data breach notification scheme. The updated law is anticipated to touch on issues relating to how “personal information” is defined, the use of third-party cookies, requirements related to the collection, use, and disclosure of personal information, and what constitutes adequate consent.

There are many other countries with data protection laws, and new countries are adopting data protection legislation with increasing frequency. Many of these laws may require consent from individuals for the use of data for various purposes, including marketing, which may reduce our ability to market our products. There is no harmonized approach to these laws and regulations globally. Consequently, we increase our risk of non-compliance with applicable foreign data protection laws and regulations when we expand internationally. We may need to change and limit the way we use personal information in operating our business and may have difficulty maintaining a single operating model that is compliant. Compliance with such laws and regulations will result in additional costs and may necessitate changes to our business practices and divergent operating models, limit the effectiveness of our marketing activities, adversely affect our business, results of operations, and financial condition, and subject us to additional liabilities.

Environmental Matters

We have no material expenditures for compliance with Federal, State or local provisions regulating the discharge of materials into the environment, or otherwise relating to the protection of the environment.

Human Capital Management

Our Team Members

We have approximately 3,200 team members, including our headquarters in Nashville, Tennessee, our manufacturing facilities in Antioch, Tennessee, our facilities in San Jose, Costa Rica, our International team and at SmileShops and popup locations. We service customers across the U.S., Puerto Rico, Canada, Australia, the U.K., Ireland, and France. . In response to the pandemic, we transitioned our team members, where possible, to a remote working environment, and in 2021, we determined to permanently provide these team members with the continued flexibility to work remotely. Our team members who have been provided space at our Nashville headquarters, should they need or choose to use it, include our executive team, as well as team members responsible for our customer care, marketing, finance, legal, people and organization, information technology, data science, and analytics. Our team members in Antioch, Tennessee are primarily responsible for developing, overseeing and carrying out manufacturing operations, and our team members in Costa Rica are primarily treatment plan setup technicians, licensed orthodontic consultants, and additional customer care team members. We believe that our relations with our team members are good. We are not a party to any collective bargaining agreements.

Company Culture

We are committed to recognizing, valuing, and engaging our top-tier talent, who are at the core of our success. We survey our team members at least twice a year to measure team engagement and the drivers behind the level of engagement and use survey results to drive team-level actions for continuous improvement, learning and development. We believe the next great idea can come from anywhere within our company, and numerous impactful initiatives have come from team member feedback, including flexible work hours, unlimited time off for exempt team members, lower deductible healthcare plans, work/life balance promotion, and wellness initiatives for physical and mental health, such as instructor-led mindfulness courses, access to virtual workouts, and resources such as access to counseling and mindfulness apps.

Our culture is built around collaboration and innovation. We created a team member focus group, our Culture Council, that allows team members to work together and propose initiatives that impact the organization, while promoting our culture and sense of inclusion and belonging. The Culture Council has initiated various events, such as virtual networking events, that connect team members of all different levels within the organization while we continue to work from home.

We are dedicated to investing in our team members and facilitating engagement and recognition initiatives across the company. We promote direct access to leadership and connect our team members to our company vision through company and team town halls and recognition-based “Fireside Chats” with our leadership. We have enhanced our internal online presence with the launch of a new intranet site that acts as our virtual office where team members can connect to the latest company communications. We also celebrate the hard work and dedication of our team members through our global recognition platform, Chompions, team happy hours or coffee chats, holiday-based events, and work anniversary celebrations, among other ways.

Talent Development and Training

We are committed to pursuing competitive advantage through filling our most important roles with the best talent. Succession planning and talent reviews were launched in 2021 globally. Our executives and their supporting leadership teams participated in training and development programs as part of this rollout, demonstrating top-down support. Succession planning discussions and efforts were completed for each team with unique action plans identified for retention and development of our critical talent and those in mission critical roles.

Inclusion, Diversity and Belonging

We are committed to the life-changing potential of inclusion and the power of diversity. We strive to listen, learn, and adapt to champion our team members. We have been seeking to achieve transformational change through a variety of initiatives, including the formation of our Inclusion, Diversity, and Belonging Council. This team is represented by highly engaged team members from across the organization. Our strategic areas of focus include learning and development, recruitment, workforce representation and retention, and a culture of belonging.

Item 1A. Risk Factors

Risk Factor Summary

Below is a summary of the principal factors that make an investment in the Company speculative or risky. This summary does not address all of the risks that we face. Additional discussion of the risks summarized in this risk factor summary, and other risks that we face, can be found below, after this summary, and should be carefully considered.

Risks Related to Our Business and Industry:

•The COVID-19 pandemic has had, and is expected to have, a material adverse impact on our business.

•We may not generate sufficient cash flow necessary to continue to invest and expand into new markets or expand market share.

•We may be unable to raise additional capital to continue to invest and expand into new markets or expand market share.

•If we fail to manage our growth effectively, our business could be materially adversely affected.

•Demand for our clear aligners may not increase as anticipated, and our business depends on sales of our clear aligners for the vast majority of our net revenue.

•Changes in the laws governing remote healthcare could hurt our ability to conduct our business.

•If our marketing and advertising campaigns are not successful, we may not be able to recover our marketing spend.

•Our performance and ability to market and sell our products depends on the success of our retail partner relationships.

•Sales of a significant portion of our aligners may depend on member’s ability to obtain reimbursement.

•Our future success may depend on our ability to enhance our existing products and services or to develop, obtain regulatory clearance for and achieve market acceptance of new products and services.

•Because our current Chairman and CEO has other business interests, he may not be able or willing to devote a sufficient amount of time to our business operations.

•We rely on third‑party suppliers for some of our manufacturing components, which subjects us to significant risks, including the potential inability to obtain or produce products on time or in sufficient quantities.

•We are dependent on some international suppliers and are expanding internationally, which exposes us to foreign operational and political risks and the need to obtain necessary foreign regulatory clearance.

•Our information technology systems are critical to our business. System integration and implementation issues and system security risks could disrupt our operations.

•If we are unable to accurately predict our volume growth and fail to hire a sufficient number of technicians in advance of such demand, the delivery time of our products could be delayed.

•If we choose to acquire or invest in new businesses or products instead of developing them ourselves, these acquisitions could result in the use of significant amounts of equity, cash, or a combination of both.

23

•We offer a financing option, which subjects us to additional regulations and compliance costs.

•An increase in interest rates on our debt would increase the servicing of our debt and reduce profitability.

•Our outstanding debt instruments contain restrictions and covenants that may limit our operating flexibility and which, if violated, could result in the acceleration of the amounts due.

•Climate change and related public focus from regulators and various stakeholders.

Risks Related to Legal and Regulatory Matters:

•Our business could be adversely affected by ongoing professional and legal challenges to our business model or by new state actions restricting our ability to provide our products and services in certain states.

•We are the subject of purported class action lawsuits and additional litigation may be brought against us.

•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.

•Complying with regulations enforced by FDA and other regulatory authorities is expensive and time‑consuming, and failure to comply could result in substantial penalties

•We may not receive the necessary authorizations to market our new products.

•Certain modifications to our products may require new 510(k) clearance or other marketing authorizations.

•Our products must be manufactured in accordance with federal, state, and international regulations, and we could be forced to recall our products or terminate production if we fail to comply with these regulations.

•Our products may cause adverse medical events that we are required to report to FDA and other governmental authorities, and if we fail to do so, we would be subject to sanctions.

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

•We are subject to data privacy laws governing our handling of PII, including personal health information, which may impose restrictions on us and our operations.

•Our systems and networks may be subject to cybersecurity breaches and other disruptions.

•We are subject to consumer protection laws that regulate our marketing practices and prohibit unfair or deceptive acts or practices. Our failure to comply could harm our business.

•Issues related to the quality and safety of our products, raw materials, or packaging could cause a product recall or discontinuation or litigation.

Risks Related to our Common Stock:

•We are a “controlled company” within the meaning of the corporate governance standards of NASDAQ. As a result, we qualify for, and rely on, exemptions from certain corporate governance standards.

24

•If we are unable to maintain effective internal control over financial reporting, investors may lose confidence in the accuracy of our financial reports and the market price of our Class A common stock may decline.

•The trading price of shares of our Class A common stock has declined significantly since our initial public offering on September 16, 2019 (“IPO”).

•We have no current plans to pay cash dividends on our Class A common stock.

•The dual‑class structure of our common stock may adversely affect the trading market for our Class A Shares.

•If we or the Pre‑IPO investors sell substantial amounts of shares of our Class A common stock, the market price of our Class A common stock could decline.

Risks Related to Organization and Structure:

•David Katzman controls a majority of the voting power of shares of our common stock eligible to vote in the election of our directors and on other matters submitted to a vote of our stockholders, and his interests may conflict with ours.

•We are a holding company. Our sole material asset is our equity interest in SDC Financial LLC (“SDC Financial”), and as such, we depend on our subsidiaries for cash to fund all of our expenses.

•SDC Financial may make distributions of cash to us substantially in excess of the amounts we use to make distributions to our stockholders and pay our expenses. To the extent we do not distribute such excess cash as dividends on our Class A common stock, the holders of membership interests of SDC Financial (“LLC Units”) (collectively, the “Continuing LLC Members”) would benefit from any value attributable to such cash as a result of their ownership of Class A common stock upon an exchange or redemption of their LLC Units.

We will be required to pay the Continuing LLC Members for certain tax benefits we may claim as a result of the tax basis step‑up we received in connection with our IPO, as well as subsequent exchanges of LLC Units for shares of Class A common stock or cash. In certain circumstances, payments under the Tax Receivable Agreement may be accelerated and/or significantly exceed the actual tax benefits we realize.

Risks Related to Our Notes:

•We have indebtedness in the form of convertible senior notes, which could adversely affect our business, financial condition and our ability to respond to changes in our business.

Certain factors may have a material adverse effect on our business, financial condition, and results of operations. You should carefully consider the following risks, together with all of the other information contained in this Annual Report on Form 10-K, including the sections titled “Cautionary Statement Regarding Forward-Looking Statements” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our financial statements and the related notes included elsewhere in this Annual Report on Form 10-K. Any of the following risks could materially and adversely affect our business, strategies, prospects, financial condition, results of operations, and cash flows. In such case, the market price of our Class A common stock could decline. Our business, prospects, financial condition, or results of operations could also be harmed by risks and uncertainties not currently known to us or that we currently do not believe are material.

25

Risks Related to Our Business and Industry

The COVID‑19 pandemic and the measures implemented to contain the spread of the virus have had, and are expected to continue to have, a material adverse impact on our business, results of operations and cash flows.

The emergence of the COVID‑19 pandemic and the resulting containment measures have had, and we expect will continue to have, a material adverse impact on our business, results of operations and cash flows, the extent and duration of which depend on numerous evolving factors and future developments that we are unable to predict, including the duration, spread and severity of the outbreak and any variant strains; the nature, extent and effectiveness of containment measures; the ability of vaccines to protect against variant strains of COVID-19; vaccine mandates that may be implemented in jurisdictions in which our business operates which could adversely affect our workforce retention and hiring; the significant stress on global supply chains, resulting in parts shortages and/or inefficiencies in production caused by the rapid increase in demand as the COVID-19 pandemic wanes; the immediate and long‑term impact on the economy, unemployment, consumer confidence and consumer spending; and how quickly and to what extent normal economic and operating conditions can resume.

The COVID‑19 pandemic and containment measures have contributed to certain negative impacts on our business, including, without limitation, the following:

•Decreased sales of our clear aligners, retainers and other products that we expect will continue.

•Closed a portion of our SmileShops based on our real estate repositioning program, local public health guidelines and evolving customer behaviors and expectations.

•Decreased sales of our oral care product line as our retail partners experience disruption due to mandated or encouraged shelter‑in‑place and social distancing policies.

•Reduced consumer demand due to deteriorating economic and political conditions such as increased unemployment, decreased salary and wage rates, and decreased consumer confidence and consumer perception of economic conditions.

•Reduced marketing efforts, which has had and may continue to have negative impacts on our ability to increase demand and improve member conversion.

•Reduced a portion of our headquarters and retail workforce, which may result in an additional loss of key employees, that in turn may significantly delay or prevent the achievement of our business objectives, and further may negatively impact our ability to recruit and retain personnel in the future.

•Revised the timing of expansion into certain international markets due to delays in the regulatory approval process of certain foreign governments.

•Experienced increased order cancellations.

•Experienced increased payment deferral requests.

•Experienced significant inflation in materials, freight and labor costs due to the rapid increase in business activity across the globe.

•Experienced delays in obtaining parts, materials, components and final assemblies because of the significant stress on the global supply chain.

26

Additionally, due to the protracted nature of the COVID‑19 pandemic, including the recent resurgence of COVID‑19 infections, as well as the evolving regulatory environment, our business and financial results may be adversely affected by numerous evolving factors, many of which we cannot control or predict, including, without limitation, our ability to:

•Manage a new work environment, including our internal controls and financial reporting, as a substantial portion of our headquarters team members are currently working remotely.

•Re‑open and operate SmileShops and popup locations in compliance with both voluntary and mandated health and safety protocols; and correspondingly, our customers’ willingness to visit and have confidence in the process of our SmileShop experience.

•Process and manufacture impression kits at a volume higher than pre COVID-19 levels.

•Gauge the impact of COVID‑19 and related potential disruptions to the operations of our suppliers, freight carriers and retail partners, including social and economic constraints, tariffs and trade barriers, facilities closures, supply chain vulnerability and stress causing delays, labor instability, and capacity reduction.

•Anticipate the potential for increased defaults on our SmilePay financing plan, including the potential for an increase in our delinquency rates and number of uncollectible accounts, as the economic impacts of COVID‑19 intensify.

•Estimate or forecast the financial impact of the COVID‑19 pandemic on our actual or future results.

The above impacts of the COVID‑19 pandemic and containment measures are likely to continue, and in some instances, may worsen. The duration and severity of the pandemic may also heighten other risks described in the “Risk Factors” section herein. The full extent to which the COVID‑19 pandemic will negatively affect our business, results of operations and cash flows is not yet known, cannot be predicted and may continue even once the pandemic is controlled and containment measures are lifted.

We may be unable to raise additional capital, which could harm our ability to compete.

We expect to expend significant capital to establish our brand, build manufacturing infrastructure, and develop both product and process technology. These initiatives may require us to raise additional capital over the next few years. We may consume available resources more rapidly than anticipated and we may not be able to raise additional funds when needed or on acceptable terms.

If we raise additional funds through further issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences, and privileges superior to those of holders of our Class A common stock. If we are unable to obtain adequate financing or financing on terms satisfactory to us, when we require it, our ability to continue to pursue our business objectives and to respond to business opportunities, challenges, or unforeseen circumstances could be significantly limited, and our business, operating results, financial condition, and prospects could be materially adversely affected.

An increase in interest rates on our borrowings would increase the cost of servicing our debt and reduce our profitability.

A portion of our outstanding debt bears interest at floating rates. As a result, to the extent we have not hedged against rising interest rates, an increase in the applicable benchmark interest rates would increase our cost of servicing our debt and could materially and adversely affect our results of operations, financial condition, liquidity, and cash flows. Such rates tend to fluctuate based on general economic conditions, general interest rates, Federal Reserve (the “Fed”) rates, and the supply of and demand for credit in the relevant interbanking market. In recent years, the Fed has incrementally raised the target range for the federal funds rate. Increases in the interest rate generally, and particularly when coupled with any significant variable rate indebtedness, could materially adversely impact our interest expenses. If interest rates increase, our debt service obligations on variable rate indebtedness would increase even though the amount borrowed remained the same, and our net

27

income and cash flows, including cash available for servicing our indebtedness, would correspondingly decrease. In addition, we may refinance our indebtedness. If interest rates or our borrowing margins increase between the time an existing financing arrangement was consummated and the time such financing arrangement is refinanced, the cost of servicing our debt would increase and our financial condition, liquidity, and cash flows could be materially and adversely affected.

We have a history of net losses and we may not achieve or maintain profitability in the future.

We have incurred net operating losses since inception. For the years ended December 31, 2021, 2020 and 2019, we incurred net losses of $(335.7) million, $(278.5) million and $(537.8) million, respectively. From inception through the present, we have spent significant funds in organizational and start‑up activities, to recruit key managers and employees, to develop our clear aligners and our suite of oral care products, to develop our manufacturing and member support resources, and for research and development. It is possible that we will not achieve profitability or that, even if we do achieve profitability, we may not maintain or increase profitability in the future.

We have a limited operating history and have grown significantly in a short period of time. If we fail to manage our growth effectively, our business could be materially adversely affected.

We were organized and began selling clear aligners manufactured by third parties in 2014, and we began selling clear aligners manufactured by us in 2016. We began selling a suite of ancillary oral care products in January 2020. Accordingly, we have a limited operating history, which makes an evaluation of our future prospects difficult. Our operating results have fluctuated in the past, and we expect our future quarterly and annual operating results to fluctuate as we focus on increasing demand for our products. 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.

In addition, we have grown rapidly since inception and anticipate further growth. Our total revenues increased from $20.6 million for the year ended December 31, 2016 to $637.6 million for the year ended December 31, 2021. The number of our employees increased from approximately 225 at December 31, 2016 to approximately 3,200 currently.

This growth has placed significant demands on our management, financial, operational, technological, and other resources, and we expect that our growth will continue to place significant demands on our management and other resources and will require us to continue developing and improving our operational, financial, and other internal controls, both in the U.S. and internationally. In particular, continued growth increases the challenges involved in a number of areas, including: recruiting and retaining sufficient skilled personnel, providing adequate training and supervision to maintain our high quality standards, and preserving our culture and values. We may not be able to address these challenges in a cost‑effective manner or at all. If we do not effectively manage our growth, we may not be able to execute on our business plan, respond to competitive pressures, take advantage of market opportunities, satisfy member requirements, or maintain high‑quality product offerings, and our business, financial condition, and results of operations could be materially harmed.

We depend on sales of our clear aligners for the vast majority of our net revenues. Demand for our clear aligners may not increase as rapidly as we anticipate due to a variety of factors, including consumer reluctance to accept teledentistry, a weakness in general economic conditions, or competitive pressures.

We expect that net revenues from sales of our clear aligners will continue to account for the vast majority of our total net revenues for the foreseeable future. Continued and widespread market acceptance of teledentistry by consumers is critical to our future success. Delivery of clear aligners via a teledentistry model represents a change from traditional orthodontic treatment, which requires in‑person visits, and consumers may be reluctant to accept this model or may not find it preferable to traditional treatment. In addition, consumers may not respond to our direct marketing campaigns, or we may be unsuccessful in reaching our target audience, particularly in foreign jurisdictions where our advertising may be more heavily regulated. If consumers prove unwilling to adopt our teledentistry model as rapidly or in the numbers that we anticipate, our operating results could be materially harmed.

28

Consumer spending habits are affected by, among other things, prevailing economic conditions, inflationary factors, levels of employment, salaries and wage rates, consumer confidence, and consumer perception of economic conditions. In many markets, dental and orthodontic reimbursement is largely out of pocket for the consumer and, as result, utilization rates can vary significantly depending on economic growth. A general slowdown in the U.S. economy and certain international economies into which we have recently expanded or plan to expand or an uncertain economic outlook could adversely affect consumer spending habits, which may result in, among other things, a decrease in the number of overall orthodontic case starts, a reduction in consumer spending on elective or higher value procedures, or a reduction in demand for dental and orthodontic services generally, each of which would have an adverse effect on our sales and operating results. Inflation and weakness in the global economy result in a challenging environment for selling dental and orthodontic technologies. If there is a reduction in consumer demand for orthodontic treatment generally, if consumers choose to use a competitive product rather than our clear aligners, or if the average selling price of our clear aligners declines as a result of economic conditions, competitive pressures, or any other reason, our business, results of operations, and financial condition could be materially harmed.

Adverse changes in, or interpretations of, laws, rules, and regulations governing remote healthcare and the practice of dentistry could have a material adverse effect on our business.

Our current business model is dependent, in part, on current laws, rules, and regulations governing remote healthcare and the practice of dentistry. If changes in laws, rules, regulations, or their interpretations are inconsistent with our current business model, we would need to adapt our business model accordingly, and our operations in certain jurisdictions may be disrupted, which could have a material adverse effect on our business, financial condition, and results of operations.

We face competition in the market for our clear aligners, and we expect competition from existing competitors and other companies that may enter the market or introduce new technologies in the future, which may decrease our net revenues.

We compete with a handful of smaller companies that collectively have limited market share in the direct‑to‑consumer clear aligner industry, including Candid Co., SnapCorrect, and Byte. We also face competition from more well‑established competitors in the traditional orthodontic industry, which requires in‑person visits, such as Align. We expect some additional competition from other teledentistry solutions, and from new entrants into the orthodontic supply or clear aligner markets. Some of these competitors may have greater resources as well as the ability to leverage existing channels in the dental market to compete directly with us. In addition, we may also face future competition from companies that introduce new technologies. We may be unable to compete with these competitors, and one or more of these competitors may render our technology obsolete or economically unattractive. As we continue to expand internationally, we will face additional competition in geographies outside the U.S. If we are unable to compete effectively with existing products or respond effectively to any new products developed by competitors, our business could be materially harmed. Increased competition may result in price reductions, reduced gross margins, reduced profitability, and loss of market share. There can be no assurance 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 spend significant amounts on advertising and other marketing campaigns to acquire new members, which may not be successful or cost‑effective.

We market our aligners and other products through an omni‑channel approach supported by media mix modeling and multitouch attribution modeling. Our marketing approach focuses on both offline activities, mainly television, and online digital marketing. We spend significant amounts on advertising and other marketing campaigns to acquire new members, and we expect our marketing expenses to increase in the future as we continue to spend significant amounts to acquire new members and increase awareness of our products. While we seek to structure our marketing campaigns in the manner that we believe is most likely to encourage consumers to use our products, we may fail to identify marketing opportunities that satisfy our anticipated return on marketing spend as we scale our investments in marketing, accurately predict member acquisition, or fully understand or estimate the conditions and behaviors that drive consumer behavior. If, for any reason, any of our marketing campaigns prove less successful than anticipated in attracting new members, we may not be able to recover our marketing spend, and our rate of member acquisition may fail to meet market expectations, either of which could adversely

29

affect our business, results of operations, and financial condition. There can be no assurance that our marketing efforts will result in increased sales of our products.

If our retail partner relationships are not successful, our ability to market and sell our products would be harmed and our financial performance would be adversely affected.

We have developed an oral care product line, which includes non‑prescription products to be offered through large, national retail partners. We have limited ability to influence the efforts of our retail partners, and relying on them for a portion of our sales could harm our business for various reasons, including:

•our retail partners may not devote sufficient resources to the sale of our products or may be unsuccessful in marketing our products;

•our agreements with retail partners may terminate prematurely due to disagreements or may result in litigation;

•we may not be able to renew existing retail partner agreements or negotiate future retail partner agreements on acceptable terms; and

•our agreements with retail partners may preclude us from entering into additional future arrangements.

Sales of a significant portion of our clear aligners may depend on our members’ ability to obtain reimbursement from third‑party payors, such as insurance carriers.

Sales of our clear aligners may depend on our members’ ability to obtain reimbursement from third‑party payors, such as insurance carriers. Any reduction in insurance or other third‑party payor reimbursement currently available to our members for our clear aligners may cause negative price pressure, which would reduce our revenues. Without a corresponding reduction in the cost to produce such products, the result would be a reduction in our overall gross profit. Similarly, any increase in the cost of such products would reduce our overall gross profit unless there was a corresponding increase in third‑party payor reimbursement. In addition, although we have contracts with certain insurance companies and are negotiating with others, healthcare initiatives in the U.S. may lead third‑party payors to decline or reduce reimbursement for our clear aligner treatment, and compliance with administrative procedures or requirements of third‑party payors may result in delays in processing approvals by those payors for members to obtain coverage for our clear aligners. Finally, as we expand our sales and marketing efforts outside of the U.S., we face additional risks associated with obtaining and maintaining coverage and securing reimbursement from foreign health care payment systems on a timely basis or at all. Failure by our members to obtain or maintain coverage or to secure adequate reimbursement for our clear aligner treatment by third‑party payors could have an adverse effect on our business, results of operations, and financial condition.

Our growth and future success may depend on our ability to enhance our existing products and services or to develop, obtain regulatory clearance for, successfully introduce, and achieve market acceptance of new products and services.

We intend to continually improve and enhance our existing products and services and/or develop and introduce new products and services in order to maintain or increase our sales. The success of new or enhanced products and services may depend on a number of factors, including anticipating and effectively addressing consumer preferences and demand, the success of our sales and marketing efforts, innovation and timely and successful research and development, obtaining necessary regulatory clearances, anticipating and responding to competing products and technological innovations, adequately protecting our intellectual property rights, effective forecasting and management of product demand, effective management of manufacturing and supply costs, and the quality of our products. There can be no assurance that we will be able to successfully develop and introduce new or enhanced products and services. Even if new or enhanced products and services are successfully introduced, they may not rapidly gain market share and acceptance.

The development of new products and services in the dental and orthodontic industry can be complex and costly. We could experience delays in the development and introduction of new and enhanced products and services, including delays in

30

obtaining any necessary regulatory clearances. Unanticipated problems in developing products and services could also divert substantial research and development resources, which may impair our ability to develop new products and services and enhancements of existing products and services, and could substantially increase our costs. If new or enhanced product and service introductions are delayed or not successful, we may not be able to achieve an acceptable return, if any, on our research and development efforts, and our business may be adversely affected. Even if we successfully innovate and develop new or enhanced products and services, we may incur substantial costs in doing so and our profitability may suffer.

Any failure in our ability to successfully develop, introduce, or achieve market acceptance of new or enhanced products and services, or any problems in the design or quality of any products or services we develop, could have a material adverse effect on our business, results of operations, and financial condition.

Because our current Chairman and Chief Executive Officer has other business interests, he may not be able or willing to devote a sufficient amount of time to our business operations, which could negatively impact our business, results of operations, and financial condition.

David Katzman, our Chairman and Chief Executive Officer, has other business interests outside of SmileDirectClub. While we believe that Mr. Katzman presently has adequate time to attend to our business, it is possible that the demands on him from other obligations could increase, with the result that he would no longer be able to devote sufficient time to the management of our business, in which case we could need the services of a full‑time Chief Executive Officer. Additionally, there is a risk of conflict of interest with other entities for which David Katzman provides services, which are monitored by our Board. In addition, we have a related party transactions policy, which details procedures to address any related party transactions with Mr. Katzman or any of these entities. The loss of Mr. Katzman to us could negatively impact our operations and financial results. See “—Risks Related to Our Organization and Structure—Pursuant to the Voting Agreement, David Katzman, our Chairman and Chief Executive Officer, controls a majority of the voting power of shares of our common stock eligible to vote in the election of our directors and on other matters submitted to a vote of our stockholders, and his interests may conflict with ours or our stockholders’ in the future.”

A disruption in the operations of our freight carriers 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 to deliver our products to our members. If the operations of these carriers are disrupted for any reason, we may be unable to deliver our products to our members on a timely basis. If we cannot deliver our products in an efficient and timely manner, our members may cancel their orders from us or seek other compensation for delays, and our net revenues and gross margin could materially decline. In a rising fuel cost environment, our freight costs will increase. If freight costs materially increase and we are unable to pass that increase along to our members for any reason or otherwise offset such increases in our cost of net revenues, our gross margin and financial results could be adversely affected.

We rely on third‑party suppliers for some of our manufacturing components and have limited control over our suppliers, which subjects us to significant risks, including the potential inability to obtain or produce quality products on a timely basis or in sufficient quantities.

We rely on third‑party suppliers for several components used in the manufacture of our products. We have limited control over our suppliers, including aspects of their specific manufacturing processes and their labor, environmental, or other practices, which subjects us to significant risks, including the following:

•inability of our suppliers to satisfy demand for our manufacturing components and to produce sufficient equipment and materials to support our growth, which could disrupt our ability to deliver our products in a timely manner;

•reduced control over manufacturing standards, controls, procedures, and policies, reduced ability to oversee the manufacturing process, and reduced ability to develop and monitor compliance with our product manufacturing specifications, each of which could negatively impact product quality and reliability;

31

•price increases, which could result in lower gross margins;

•entry into non‑cancelable minimum purchase commitments, which could impact our ability to adjust our capacity and inventory and could lead to excess and obsolete equipment and supplies;

•technology changes by our suppliers, which could disrupt access to required manufacturing capacity or require expensive, time‑consuming development efforts to adapt and integrate new equipment or processes;

•the delay or failure of a key supplier to perform its obligations to us due to financial, operating, or other difficulties;

•difficulties in quickly establishing additional supplier relationships on commercially acceptable terms in the event that we experience difficulties with our existing suppliers;

•infringement or misappropriation of our intellectual property;

•exposure to natural catastrophes, political unrest, terrorism, labor disputes, and economic instability resulting in the disruption of trade;

•changes in local economic conditions in areas where our suppliers or logistics providers are located;

•the imposition of new laws and regulations, including those relating to labor conditions, quality and safety standards, imports, duties, taxes, and other charges on imports, as well as trade restrictions and restrictions on currency exchange or the transfer of funds; and

•insufficient warranties and indemnities.

If any of these risks were to materialize, we could face production interruptions, delays, or inefficiencies or could be forced to curtail or cease operations, which could have a material adverse effect on our business, results of operations, and financial condition.

If we encounter manufacturing problems or delays, our ability to generate revenue will be limited.

Historically, we purchased our clear aligners and retainers from third‑party manufacturers. In 2016, we opened our first manufacturing facility in Antioch, Tennessee to lower our manufacturing costs, increase supply redundancy, and add capacity to support growth. We are in the process of completing an additional manufacturing facility in Columbia, Tennessee, which will be fully operational in 2022. To date, we have incurred significant capital expenditures related to these facilities, and we expect that capital expenditures will continue to be significant as we further upgrade our Tennessee facilities. These costs could increase significantly, and there is no assurance that the final costs will not be materially higher than anticipated. We are also exploring alternative site manufacturing capabilities both domestically and abroad, which would require additional capital expenditures.

We now manufacture all of our own clear aligners and retainers. We have experienced manufacturing delays as we have rapidly expanded our in‑house manufacturing capabilities, and there can be no assurance that these manufacturing or quality control problems will not continue as we continue to scale‑up and automate our production, or that we will be able to do so in a timely manner or at commercially reasonable costs. If we are unable to manufacture a sufficient supply of product, maintain control over expenses, or otherwise adapt to anticipated growth, or if we underestimate growth, we may not have the capability to satisfy market demand, and our business and reputation in the marketplace will suffer. We may also encounter defects in materials and/or workmanship, which could lead to a failure to adhere to regulatory requirements. Any defects could delay operations at our facilities, lead to regulatory fines, or halt or discontinue manufacturing indefinitely.

32

Our manufacturing processes rely on complex three‑dimensional scanning, geometrical manipulation and modeling technologies, and sophisticated 3D printing. Since our clear aligners and retainers are designed for individual members, we manufacture them to fill prescriptions rather than maintaining inventories. If demand for our clear aligners and retainers exceeds our manufacturing capacity, we could develop a substantial backlog of member orders, or would otherwise need to outsource to other manufacturers, which would affect our profitability.

Our manufacturing facilities are subject to periodic regulatory inspections by FDA and other regulatory agencies. If we fail in the future to maintain facilities in accordance with applicable Quality System Regulations enforced by FDA or other regulatory requirements, our manufacturing process could be suspended or terminated, which would have a material adverse effect on our business, results of operations, and financial condition.

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

We rely on some third party suppliers in Europe and Asia who supply, among other things, certain of the technology and raw materials used in our manufacturing processes. Our reliance on international operations exposes us to risks and uncertainties, including: controlling quality of supplies; political, social, and economic instability; interruptions and limitations in telecommunication services; product or material delays or disruption; trade restrictions and changes in tariffs; import and export license requirements and restrictions; fluctuations in currency exchange rates; and potential adverse tax consequences. If any of these risks were to materialize, our results of operations may be harmed.

The majority of our operations are conducted in three geographic locations. Any disruption at our facilities could increase our expenses.

Aside from our SmileShops and popup locations, all of our business and manufacturing operations, in addition to some of our customer service operations, are conducted in and around Nashville, Tennessee, including a new manufacturing location in Columbia, Tennessee. All of our treatment planning operations, as well the remainder of our customer service operations, are conducted in Costa Rica. We take precautions to safeguard our facilities, including insurance, health and safety protocols, and off‑site storage of computer data. However, a natural disaster, such as a fire, flood, or earthquake, could cause substantial delays in our operations, damage or destroy our manufacturing equipment or inventory, and cause us to incur additional expenses. The insurance we maintain against fires, floods, earthquakes, and other natural disasters may not be adequate to cover our losses in any particular case. Any material disruption could materially damage member and business partner relationships and subject us to significant reputational, financial, legal, and operational consequences.

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, results of operations, and financial condition.

We depend on our information technology systems, as well as those of third parties, to develop products and services, operate our website, host and manage our services, store data, process transactions, respond to user inquiries, and manage our operations. Any material disruption or slowdown of our systems or those of third parties upon whom we depend, including a disruption or slowdown caused by our failure to successfully manage significant increases in user volume or successfully upgrade our or their systems, system failures, viruses, security breaches, or other causes, could cause information, including data related to orders, to be lost or delayed, which could result in delays in the delivery of products to members or lost sales, which could reduce demand for our products, harm our brand and reputation, and cause our revenue to decline. If changes in technology cause our information systems, or those of third parties upon whom we depend, to become obsolete, or if our or their information systems are inadequate to handle our growth, we could lose members, and our business, financial condition, and results of operations could be adversely affected.

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 member information, and improving service levels

33

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 business.

Our international operations subject us to additional costs and risks, and our continued international expansion will subject us to additional costs and risks that may adversely impact our business, results of operations, and financial condition.

We have entered markets in Canada, Australia, U.K., Ireland, New Zealand, Hong Kong, Singapore, Germany, Austria, Spain, and France. We have recently announced changes to our international operations and our plans to exit certain markets (see Note 21). There are significant costs and risks inherent in conducting business in international markets. Exiting, or attempts to expand into additional foreign markets, we will be subject to new business risks, in addition to regulatory risks. In addition, expansion into foreign markets imposes additional burdens on our executive and administrative personnel, finance and legal teams, research and marketing teams, and general managerial resources.

We have limited experience with regulatory environments and market practices internationally, and we may not be able to penetrate or successfully operate in new markets. We may also encounter difficulty expanding into new international markets because of limited brand recognition in certain parts of the world, leading to delayed acceptance of our products and services by consumers in these new international markets. If we are unable to continue to expand internationally and manage the complexity of international operations successfully, our business, results of operations, and financial condition could be adversely affected. If our efforts to introduce our products and services into foreign markets are not successful, we may have expended significant resources without realizing the expected benefit. Ultimately, the investment required for expansion into foreign markets could exceed the results of operations generated from this expansion.

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

Although the U.S. dollar is our reporting currency, a portion of our net revenues and net income is and will be generated in foreign currencies. Net revenues and net income generated outside of the U.S. are translated into U.S. dollars using exchange rates effective during the respective period and are affected by changes in exchange rates. As a result, negative movements in currency exchange rates against the U.S. dollar will adversely affect our net revenues and net income in our consolidated financial statements. The exchange rates between the U.S. dollar and foreign currencies have fluctuated substantially in recent years and may continue to fluctuate substantially in the future. We may in the future enter into currency hedging transactions in an effort to cover some of our exposure to foreign currency exchange fluctuations. These transactions may not operate to fully or effectively hedge our exposure to currency fluctuations, and, under certain circumstances, these transactions could have an adverse effect on our business and financial condition.

We also experienced rising inflationary pressures in 2021 and expect such pressures to continue in 2022. Inflationary factors, such as increases in our cost of revenues, advertising costs and other selling and operating expenses, may adversely affect our operating results. A high rate of inflation may have an adverse effect on our ability to maintain and increase our gross margin or to maintain current levels of selling, general, administrative and other operating expenses as a percentage of revenues if the selling price of our products do not increase with these increased costs.

The results of the U.K.’s withdrawal from the E.U. may have a negative effect on global economic conditions, financial markets, and our business.

On January 31, 2020 the U.K. left the European Union (the “E.U.”) (commonly referred to as “Brexit”) and entered a transition period with the E.U. On December 30, 2020, the U.K. and the E.U. entered into an agreement regarding their future relationship, the Trade and Cooperation Agreement (the “trade agreement”). The trade agreement offers U.K. and EU companies preferential access to each other’s markets, ensuring imported goods will be free of tariffs and quotas (subject to rules of origin requirements). However, significant political and economic uncertainties remain in connection with the ultimate future of the U.K. and its relationship with the E.U. The uncertainty surrounding the terms following Brexit could negatively impact markets and cause weaker macroeconomic conditions that could continue for the foreseeable future.

34

Adverse macroeconomic consequences, such as deterioration in economic conditions, may negatively impact future sales of our products and, particularly in European countries, may negatively impact our international expansion, either of which could have an adverse effect on our business, financial condition, and results of operations.

We depend on key personnel to operate our business, and if we are unable to retain and attract key personnel, we may be unable to pursue business opportunities or develop our products.

We are dependent on the key employees in our clinical engineering, technology development, sales, training, marketing, and management teams. The loss of the services provided by certain of these individuals may significantly delay or prevent the achievement of our 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. We may not be successful in retaining our key personnel or their services, or in attracting and retaining personnel with the advanced qualifications necessary for the further development of our business. If we are unable to retain and attract key personnel, our business could be materially harmed.

If we are unable to accurately predict our volume growth, and fail to hire a sufficient number of technicians in advance of such demand, the delivery time of our products could be delayed, which could adversely affect our results of operations.

Treatment planning, a key step leading to our manufacturing process, relies on sophisticated computer technology requiring new technicians to undergo an extensive training process. Training setup technicians takes several weeks, and it takes several months for a new technician to achieve his or her full capacity. As a result, if we are unable to accurately predict our volume growth, we may not have a sufficient number of trained technicians to deliver our products within the time frame our members expect. Such a delay could cause us to lose existing members or fail to attract new members. This could cause a decline in our net revenues and net income and could adversely affect our results of operations.

If we choose to acquire or invest in new businesses, products, or technologies, instead of developing them ourselves, these acquisitions or investments could disrupt our business and could result in the use of significant amounts of equity, cash, or a combination of both.

From time to time we may seek to acquire or invest in new businesses, products, or technologies, instead of developing them ourselves. Acquisitions and investments involve numerous risks, including:

•timing of regulatory approvals and clearances;

•the inability to complete the acquisition or investment;

•disruption of our ongoing businesses and diversion of management attention;

•difficulties in integrating the acquired entities, products, or technologies;

•risks associated with acquiring intellectual property;

•difficulties in operating the acquired business profitably;

•the inability to achieve anticipated synergies, cost savings, or growth;

•potential loss of key employees, particularly those of the acquired business;

•difficulties in transitioning and maintaining key partner, distributor, and supplier relationships;

•risks associated with entering markets in which we have no or limited prior experience;

•increased operating costs or reduced earnings;

35

•the use of significant amounts of cash, the incurrence of debt, and/or the assumption of significant liabilities; and

•dilutive issuances of equity securities, which may be sold at a discount to market price.

Any of these factors could materially harm our stock price, business, financial condition, and results of operations.

We offer a financing option to our members, which could adversely affect our financial results.

Other than in certain foreign jurisdictions where prohibited, we offer all of our members our SmilePay option, a financing plan that does not require a credit check. Approximately 60% of our members chose to finance their treatment through SmilePay for the year ended December 31, 2021. As of December 31, 2021, SmilePay amounted to approximately $243.8 million in net receivables and an associated delinquency rate of approximately 9% of revenue. We may experience an increase in payment defaults and uncollectible accounts and may be required to increase our reduction in revenue, which would adversely affect our net income. In addition, extended payment terms decrease our cash flow from operations.

Our SmilePay financing option subjects us to additional regulations and compliance and other costs.

Our SmilePay program subjects us to complex consumer financial protection laws and regulations, among others. We must comply with all applicable U.S. federal and state legal and regulatory regimes, and all applicable laws and regulatory regimes in foreign jurisdictions where we operate SmilePay, including but not limited to those governing consumer retail installment credit transactions. Certain U.S. federal and state laws and laws in foreign jurisdictions where we operate SmilePay generally regulate the rate or amount of finance charges and fees and require certain disclosures for consumer finance transactions. If we fail to comply with applicable laws, regulations, rules, and guidance, our business could be adversely affected.

Compliance with these laws and regulatory requirements is costly and time‑consuming and limits our operational flexibility. Further, failure to comply with these laws and regulatory requirements may, among other things, limit our ability to collect all or part of the balance owing on a member’s SmilePay account. As a result, we may not be able to collect on unpaid principal or finance charges. In addition, non‑compliance could subject us to damages, revocation of required licenses or registrations, class action lawsuits, administrative enforcement actions, rescission rights held by investors in securities offerings, and civil and criminal liability, which may harm our business and may result in members rescinding their SmilePay account agreements.

We currently contract with third‑party providers to manage the administrative services and maintain regulatory compliance for our financing offers (including SmilePay), as well as to provide the enabling software. Some international regulations may limit the availability of SmilePay to members in certain jurisdictions without our first obtaining a license or engaging a third party to provide such financing, thereby limiting our profitability on sales to members in those locations. While both we and our provider are in the process of obtaining licenses in these jurisdictions, we cannot guarantee that the necessary licenses will be obtained by us or our provider on a timely basis or at all.

Refunds and cancellations could harm our business.

We allow our customers to return aligners, subject to our Smile Guarantee refund policy, which allows any member to return their aligners for any reason within the first 30 days of their treatment and receive a full refund. Additionally, members who follow their treatment plan and do not love their smile may return the remainder of their aligners for a pro‑rated refund based on the number of aligners used or get additional aligners, at no additional cost, to address their treatment concerns. At the time of sale, we establish a reserve for aligner returns, based on historical experience and expected future returns, which is recorded as a reduction of sales. If we experience a substantial increase in refunds, our cancellation reserve levels might not be sufficient and our business, operating results, and financial condition could be harmed.

36

Debt instruments we may have in the future may contain restrictions and covenants that could limit our operating flexibility and which, if violated, could result in the acceleration of the amounts due.

Debt instruments we may have in the future may contain financial ratios and certain other covenants, which we would be required to satisfy. Complying with such restrictions and covenants may make it more difficult for us to successfully execute our business strategy. We may need to reduce the amount of our indebtedness outstanding from time to time in order to comply with such financial ratios, though no assurance can be given that we will be able to do so.

Our failure to maintain required financial ratios or our breach of the other restrictions or covenants under future debt instruments could result in an event of default under the applicable agreement. Such a default may allow our lenders under the applicable agreement to accelerate all of our outstanding indebtedness and other amounts due and, if we do not pay these amounts, proceed against the collateral securing these obligations. In the future, such a default may also result in the acceleration of other indebtedness.

Changes affecting the availability of the London Interbank Offered Rate (‘LIBOR’) may have consequences for the Company that cannot yet reasonably be predicted.

We may have outstanding debt with variable interest rates based on LIBOR. In July 2017, the U.K.’s Financial Conduct Authority, which regulates LIBOR, announced it intended to phase out LIBOR by the end of 2021. The cessation date for submission and publication of rates for certain tenors of LIBOR has since been extended until mid‑2023. Notwithstanding this extension, a joint statement by key regulatory authorities called on banks to cease entering into new contracts that use LIBOR as a reference rate as soon as practicable, but no later than December 31, 2021. In the United States, the Alternative Reference Rates Committee has proposed the Secured Overnight Financing Rate (“SOFR”) as an alternative to LIBOR. It is not presently known whether SOFR or any other alternative reference rates that have been proposed will attain market acceptance as replacements of LIBOR. Any new benchmark rate will likely not replicate LIBOR exactly, which could impact our credit facilities. In addition, the overall financial markets may be disrupted as a result of the phase‑out or replacement of LIBOR. Uncertainty as to the nature of such phase out and selection of an alternative reference rate, together with disruption in the financial markets, could increase in the cost of our variable rate indebtedness.

We may not generate sufficient cash flow to service our debt, pay our contractual obligations, and operate our business.

Our ability to make payments on our indebtedness and contractual obligations, and to fund our operations, depends on our future performance and financial results, which, to a certain extent, are subject to general economic, financial, competitive, regulatory, interest rate, and other factors that are beyond our control. Although senior management believes that we have and will continue to have sufficient liquidity, there can be no assurance that our business will generate sufficient cash flow from operations in the future to service our debt, pay our contractual obligations, and operate our business. In addition, the breach of certain covenants or restrictions in certain of our debt instruments would permit the lenders to declare all borrowings thereunder to be immediately due and payable and, if provided for in the future, cross default provisions may entitle our other lenders to accelerate their loans.

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 tax laws both within and outside the U.S., regulations and/or rates, structural changes in our business, new or changes to accounting pronouncements, non‑deductible goodwill impairments, 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, the future levels of tax benefits of equity‑based compensation, changes in overall levels of pretax earnings, or changes in the valuation of our deferred tax assets and liabilities. Additionally, we could be challenged by state and local tax authorities as to the propriety of our sales tax compliance, and our results could be materially impacted by these compliance determinations.

37

In addition, our effective tax rate may vary significantly depending on our stock price. The tax effects of the accounting for share‑based compensation may significantly impact our effective tax rate from period to period. In periods in which our stock price is higher than the grant price of the share‑based compensation vesting in that period, we will recognize excess tax benefits that will decrease our effective tax rate. In periods in which our stock price is lower than the grant price of the share‑based compensation vesting in that period, our effective tax rate may increase. The amount and value of share‑based compensation issued relative to our earnings in a particular period will also affect the magnitude of the impact of share‑based compensation on our effective tax rate. These tax effects are dependent on our stock price, which we do not control, and a decline in our stock price could significantly increase our effective tax rate and adversely affect our financial results.

Climate change and related public focus from regulators and various stakeholders could have a material adverse effect on our business, financial condition, cash flows and results of operations.

Climate change is receiving ever increasing attention worldwide. Many scientists, legislators and others attribute global warming to increased levels of greenhouse gases, which has led to significant legislative and regulatory efforts to limit greenhouse gas emissions. The U.S. Environmental Protection Agency (“EPA”) has published findings that emissions of carbon dioxide, methane, and other greenhouse gases (“GHGs”) present an endangerment to public health and the environment because emissions of such gases are, according to the EPA, contributing to the warming of the earth's atmosphere and other climate change.

Climate changes, such as extreme weather conditions, decreased water availability and overall temperature shifts, may have physical impacts on our facilities and operations, as well as those of our third-party manufacturers. Such impacts are geographically specific, highly uncertain and may result in diminished availability of materials, indirect financial risks passed through our supply chain and adverse impacts on our financial performance and operations.

These considerations may also result in international, national, regional or local legislative or regulatory responses to mitigate greenhouse gas emissions. Timing and scope of any regulations are uncertain, and regulation could result in additional costs of compliance, increased energy, transportation and materials costs and other additional expenses to improve the efficiency of our products, facilities and operations.

Relatedly, the expectations of our customers, stockholders and employees have heightened in areas such as the environment, social matters and corporate governance. Increased public focus requires us to provide information on our approach to these issues, including certain climate-related matters such as mitigating greenhouse gas emissions, and continuously monitor related reporting standards. A failure to adequately meet stakeholder expectations may result in a loss of business, diminished ability to successfully market our products to new and existing customers, diluted market valuation or an inability to attract and retain key personnel.

Risks Related to Legal and Regulatory Matters

Our business could be adversely affected by ongoing professional and legal challenges to our business model or by new state actions restricting our ability to provide our products and services in certain states.

A number of dental and orthodontic professionals and their trade associations believe that clear aligners are appropriate for only a limited percentage of their patients and that in person office visits are required. National and state dental associations and dental boards have issued statements and taken out advertisements discouraging use of orthodontics using a teledentistry platform and have filed sham petitions or complaints with governmental agencies. These same trade associations have also engaged in a coordinated campaign to generate legislation precluding or otherwise restricting teledentistry for orthodontic care. Some state legislators have proposed legislation designed to preclude or significantly limit teledentistry. Increased market acceptance of our remote clear aligner treatment may depend, in part, upon the recommendations of dental and orthodontic professionals and associations, as well as other factors including effectiveness, safety, ease of use, reliability, aesthetics, and price compared to competing products.

38

Furthermore, our ability to conduct business in each state is dependent, in part, upon that particular state’s treatment of remote healthcare and that state dental board’s regulation of the practice of dentistry, each of which is subject to changing political, regulatory, and other influences. There is a risk that state authorities may find that our contractual relationships with our doctors violate laws and regulations prohibiting the corporate practice of dentistry, which generally bar the practice of dentistry by entities. Two state dental boards established rules or interpreted existing rules in a manner that purports to limit or restrict our ability to conduct our business as currently conducted. The Georgia Board of Dentistry passed a new rule that requires a licensed dentist to be present when 3D oral images are taken by a dental assistant, and the Board of Dental Examiners of Alabama has interpreted existing rules to require “direct supervision” (meaning the dentist must be physically present somewhere in the building) for the taking of digital oral images. In California, an investigator for the California Dental Board has engaged in what we believe to be a pattern of anticompetitive conduct to interfere with our operations in that state. In Georgia, Alabama, and California, we have filed lawsuits in Federal court against the dental boards and their individual members alleging, among other things, violations of the Sherman Act, and we will continue to pursue litigation where appropriate to combat anticompetitive or otherwise illegal behavior targeting our business model. The Federal Trade Commission and Department of Justice have filed joint amicus briefs on our behalf in the California, Alabama, and Georgia lawsuits. In addition, a national orthodontic association continues to meet with various dental boards, legislatures and regulatory bodies across the country in an effort to advocate for new laws, rules and regulations that could have the effect of interfering with our business model. Although, none of these efforts have resulted in any laws, rules and regulations being passed to date that would materially impact our business model, it is possible that the laws, rules and regulations governing the practice of dentistry and orthodontics in one or more states may change or be interpreted in a manner unfavorable to our business. If adverse laws or regulations are adopted or any such claims are successful, and we were unable to adapt our business model accordingly, our operations in such states would be disrupted, which could have a material adverse effect on our business, financial condition, and results of operations.

We are the subject of purported class action lawsuits, and additional litigation may be brought against us in the future.

In September 2019, a putative class action on behalf of a consumer and three orthodontists was brought against us in the U.S. District Court for the Middle District of Tennessee seeking monetary damages for breach of warranty, false advertising under the Lanham Act, common law fraud, and various state consumer protection statutes relating to our advertising. Following a proactive voluntary dismissal by the majority of consumer plaintiffs, one consumer has since sought to rejoin the Middle District of Tennessee litigation or, in the alternative, to intervene, which the Court granted. That ruling has been appealed, and the Court stayed the consumer claims pending the appeal. On June 25, 2021, the appellate court reversed the district court and remanded with instructions to order the intervening plaintiff to mandatory binding arbitration. All remaining consumer claims remain stayed. Litigation is in the discovery stage. On October 13, 2021, the Court entered an Amended Scheduling Order, effectively staying merits discovery, and setting deadlines of March 30, 2022, to complete class certification fact discovery and September 2, 2022, to complete briefing on motions regarding class certification. While we believe these claims to be without merit, there can be no assurance regarding the outcome of this matter.

In addition, from September to December 2019, a number of purported stockholder class action complaints were filed in the U.S. District Court for the Middle District of Tennessee and in state courts in Tennessee, Michigan and New York against us, the members of our board of directors, certain of our current officers, and the underwriters in our IPO. The complaints all allege, among other things, that our registration statement filed with the SEC on August 16, 2019, and accompanying amendments, and the Prospectus filed with the SEC on September 13, 2019 (“Final IPO Prospectus”), in connection with our initial public offering were inaccurate and misleading, contained untrue statements of material facts, omitted to state other facts necessary to make the statements made not misleading, and omitted to state material facts required to be stated therein. The complaints seek unspecified money damages, other equitable relief, and attorneys’ fees and costs. On February 26, 2020, Defendants prevailed on their motion to dismiss the Michigan state court action. On January 22, 2020, the New York state court action was stayed. On February 10, 2020, Defendants moved to stay or dismiss the Tennessee state court action. On June 4, 2020, the court denied that motion. On August 3, 2020, Defendants filed an application for interlocutory appeal with the court of appeals, which was denied. Defendants filed a motion objecting to class certification. On September 21, 2020, Defendants filed an application for interlocutory appeal with the Tennessee Supreme Court, which was denied. On October 2, 2020, Plaintiffs moved for class certification, which Defendants opposed on January 25, 2021. On April 28, 2021, the court ruled in favor of the Plaintiffs class certification. The Company filed its notice of appeal on May 4, 2021. That appeal was

39

fully briefed as of October 6, 2021 and has been pending since oral argument on December 2, 2021. All trial court proceedings are stayed during the pendency of the appeal.

Also in November and December 2019 and March 2020, three stockholder derivative actions were filed against the members of our board of directors, certain of our current officers and related entities. The three derivative actions were consolidated, and the consolidated complaint alleges, among other things, that the defendants breached their fiduciary duties by allowing the Final IPO Prospectus to contain materially misleading statements and by participating in insider selling in connection with the IPO. The consolidated complaint seeks, among other things, money damages on behalf of the Company, restitution and/or disgorgement from the selling director defendants and cancellation of the Company’s Class B common stock. On May 28, 2021, the Court granted the Company’s motion to dismiss. On June 24, 2021, the plaintiffs filed their notice of appeal. The matter is now pending before the Delaware Supreme Court, with all briefing on the appeal filed as of September 28, 2021. A hearing on the appeal was held on December 8, 2021, and on January 6, 2022, the Delaware Supreme Court affirmed the dismissal of the derivative action on the basis of and for the reasons assigned by the Court of Chancery.

While we believe these claims to be without merit, there can be no assurance that additional claims alleging the same or similar facts will not be filed. Any litigation could result in substantial costs and a diversion of management’s attention and resources.

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.

Our success will depend in part on our ability to maintain existing intellectual property and to obtain and maintain further intellectual property protection for our products and services, both in the U.S. and in other countries. We attempt to protect our intellectual property rights through a combination of patent, trademark, copyright, and trade secret laws, as well as licensing agreements and third‑party confidentiality and assignment agreements. Our inability to do so could harm our competitive position. We have 32 active U.S. patents, seven allowed U.S. patents, and numerous pending U.S. and global patent applications.

We rely on our portfolio of issued and pending patent applications in the U.S. and 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. While we generally apply for patents in those countries where we intend to make, have made, use, or sell patented products, we may not accurately predict all of the countries where patent protection will ultimately be desirable. If we fail to timely file for a patent, we may be precluded from doing so at a later date. 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. patent and intellectual property laws. There can be no assurance that any of our patents, any patents licensed to us, or any patents which we may be issued in the future, will provide us with a competitive advantage or afford us protection against infringement by others, or that the patents will not be successfully challenged or circumvented by third parties, including our competitors. Further, there can be no assurance that we will have adequate resources to enforce our patents.

We also rely on protection of copyright, trade secrets, know‑how, and confidential and proprietary information. We generally enter into confidentiality and non‑compete agreements with our employees, consultants, and collaborative partners upon their 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. The exposure of our trade secrets and other proprietary information 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. Further, other parties may independently develop substantially equivalent know‑how and technology.

40

We rely on our trademarks, trade names, and brand names to distinguish our products and services from the products and services of our competitors, and have registered or applied to register many of these trademarks. There can be no assurance that our trademark applications will be approved. Third parties may also oppose our trademark applications, or otherwise challenge our use of the trademarks. In the event that our trademarks are successfully challenged, we could be forced to rebrand our products and services, which could result in loss of brand recognition, and could require us to devote resources advertising and marketing new brands. Further, there can be no assurance that competitors will not infringe our trademarks, or that we will have adequate resources to enforce our trademarks. We also license third parties to use our trademarks. In an effort to preserve our trademark rights, we enter into license agreements with these third parties, which govern the use of our trademarks and require our licensees to abide by quality control standards with respect to the goods and services that they provide under our trademarks. Although we make efforts to police the use of our trademarks by our licensees, there can be no assurance that these efforts will be sufficient to ensure that our licensees abide by the terms of their licenses. In the event that our licensees fail to do so, our trademark rights could be diluted.

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 proprietary rights claimed by third parties to be pertinent to the manufacture, use, or sale of our products or provision of our services. These 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 and provide our services, 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 or providing our services. Any of these results from litigation could adversely affect our business, financial condition, and results of operations.

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

Extensive litigation over patents and other intellectual property rights is common in the dental and orthodontic industry. We have in the past and may in the future be the subject of patent or other litigation. From time to time, we have received and may in the future receive letters from third parties drawing our attention to their patent rights. While we do not believe that we infringe upon any valid and enforceable rights that have been brought to our attention, and we take necessary steps to ensure that we do not infringe on the rights of others, 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.

Complying with regulations enforced by FDA and other regulatory authorities is expensive and time‑consuming, and failure to comply could result in substantial penalties.

Some of our products are considered medical devices, which are subject to extensive regulation in the U.S. and internationally. FDA regulations are wide ranging and govern, among other things:

•product design, development, manufacturing, and testing;

•product labeling;

•product storage;

41

•product safety;

•pre‑market clearance or approval;

•complaint handling and corrective actions;

•recordkeeping procedures and postmarket surveillance;

•advertising and promotion; and

•product sales and distribution.

The regulations to which we are subject are complex. Regulatory changes could result in restrictions on our ability to carry on or expand our operations, higher than anticipated costs, or lower than anticipated sales. Our failure to comply with applicable regulatory requirements could result in enforcement action by FDA or state agencies, which may include any of the following sanctions:

•warning letters, fines, injunctions, consent decrees, and civil penalties;

•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;

•withdrawing clearance or pre‑market approvals that have already been granted; and

•criminal prosecution.

If any of these events were to occur, they could harm our business.

We may not receive the necessary authorizations to market our new products, and any failure to timely do so may adversely affect our ability to grow our business.

Our future success will also depend on our ability to obtain regulatory approval or clearance of certain new products. Before we can sell a new medical device in the U.S., or market a new use of, new claim for, or significant modification to a legally marketed device, we must first obtain either clearance under Section 510(k) of the FD&C Act or other FDA authorizations, if applicable, unless an exemption applies.

In the 510(k) clearance process, before a device may be marketed, FDA must determine that a proposed device is “substantially equivalent” to a legally‑marketed “predicate” device. To be “substantially equivalent,” the proposed device must have the same intended use as the predicate device, and either have the same technological characteristics as the predicate device or have different technological characteristics, not raise different questions of safety or effectiveness than the predicate device, and be as safe and as effective as the predicate device. The 510(k) clearance process can be expensive and uncertain and can take from three to 12 months, but may last significantly longer. Clinical data may be required in connection with an application for 510(k) clearance. Furthermore, even if we are granted regulatory clearances or approvals, they may include limitations on the indications for use or intended uses of the device, which may limit the market for the device.

We market our clear aligners in the U.S. pursuant to 510(k) clearance.

42

FDA can delay, limit, or deny 510(k) clearance, or other approval or reclassification, of a device for many reasons, including:

•we may be unable to demonstrate to FDA’s satisfaction that the products or modifications are substantially equivalent to a proposed predicate device or safe and effective for their intended uses;

•we may be unable to demonstrate that the clinical and other benefits of the device outweigh the risks; and

•the applicable regulatory authority may identify deficiencies in our submissions or in the facilities or processes of our third party contract manufacturers.

Any delay or failure to obtain necessary regulatory clearances or approvals could harm our business.

In addition, FDA may change its policies, adopt additional regulations, revise existing regulations, or take other actions, or Congress may enact different or additional statutory requirements, which may prevent or delay clearance of our future products under development or impact our ability to modify our currently marketed products on a timely basis. Such policy, statutory, or regulatory changes could impose additional requirements upon us that could delay our ability to obtain new 510(k) clearances, increase the costs of compliance, or restrict our ability to maintain our current marketing authorizations.

We will also need to obtain regulatory approval in other foreign jurisdictions in which we plan to market and sell our products, although we already have regulatory approval in Canada, Australia, the U.K., Ireland, France, and the E.U. The time required to obtain registrations or approvals, if required by other countries, may be longer than that required for FDA clearance, and requirements for such registrations, clearances, or approvals may significantly differ from FDA requirements. If we modify our products, we may need to apply for additional regulatory approvals before we are permitted to sell the modified product. In addition, we may not continue to meet the quality and safety standards required to maintain the authorizations that we have received. If we are unable to maintain our authorizations in a particular country, we will no longer be able to sell the applicable product in that country.

Failure to comply with these rules, regulations, self‑regulatory codes, circulars, and orders could result in significant civil and criminal penalties and costs and could have a material adverse impact on our business. Also, these regulations may be interpreted or applied by a prosecutorial, regulatory, or judicial authority in a manner that could require us to make changes in our operations or incur substantial defense and settlement expenses. Even unsuccessful challenges by regulatory authorities or private relators could result in reputational harm and the incurring of substantial costs. In addition, many of these laws are vague or indefinite and have not been interpreted by the courts and have been subject to frequent modification and varied interpretation by prosecutorial and regulatory authorities, increasing compliance risks.

Certain modifications to our products may require new 510(k) clearance or other marketing authorizations and may require us to recall or cease marketing our products.

Once a medical device is permitted to be legally marketed in the U.S. pursuant to a 510(k) clearance, a manufacturer may be required to notify FDA of certain modifications to the device. Manufacturers determine in the first instance whether a change to a product requires a new premarket submission, but FDA may review any manufacturer’s decision. FDA may not agree with our decisions regarding whether new clearances or approvals are necessary. We have made modifications to our products in the past and have determined, based on our review of the applicable FDA regulations and guidance, that in certain instances new 510(k) clearances or other premarket submissions were not required. We may make similar modifications or add additional features in the future that we believe do not require a new 510(k) clearance. If FDA disagrees with our determinations and requires us to submit new 510(k) notifications, we may be required to cease marketing or to recall the modified product until we obtain clearance or approval, and we may be subject to significant regulatory fines or penalties.

43

Our products must be manufactured in accordance with federal, state, and international regulations, and we could be forced to recall our products or terminate production if we fail to comply with these regulations.

The methods used in, and the facilities used for, the manufacture of our products must comply with FDA’s Quality System Regulation which is a complex regulatory scheme that covers the procedures and documentation of, among other requirements, the design, testing, validation, verification, complaint handling, production, process controls, quality assurance, labeling, supplier evaluation, packaging, handling, storage, distribution, installation, servicing, and shipping of medical devices. Furthermore, we are required to verify that our suppliers maintain facilities, procedures, and operations that comply with our quality standards and applicable regulatory requirements. FDA enforces the Quality System Regulation through, among other oversight methods, periodic announced or unannounced inspections of medical device manufacturing facilities, which may include the facilities of contractors, suppliers, or contract manufacturing organizations. Our products are also subject to similar state regulations as well as similar laws and regulations of foreign countries. Our failure to comply with the Quality System Regulation or similar requirements could result in enforcement actions, sanctions, recalls, detentions, seizures, or similar market actions with respect to our products, among other potential consequences. If any of these or other events occur, there could be a negative impact on the supply of our products, our reputation could be harmed, we could be exposed to product liability claims, and we could lose customers and suffer reduced revenue and increased costs.

Our products may cause or contribute to adverse medical events that we are required to report to FDA and other governmental authorities, and if we fail to do so, we would be subject to sanctions that could harm our reputation, business, results of operations, and financial condition. The discovery of serious safety issues with our products, or a recall of our products either voluntarily or at the direction of FDA or another governmental authority, could have a negative impact on us.

We are required to timely file various reports with FDA, including reports required by the medical device reporting regulations which require us to report to FDA when we receive or become aware of information that reasonably suggests that one of our products may have caused or contributed to a death or serious injury or malfunctioned in a way that, if the malfunction were to recur to the device or a similar device that we market, could cause or contribute to a death or serious injury. If we fail to comply with our reporting obligations, FDA or other governmental authorities could take action, including warning letters, untitled letters, administrative actions, criminal prosecution, imposition of civil monetary penalties, revocation of our device clearance, seizure of our products, or delay in clearance of future products. FDA and certain foreign regulatory bodies have the authority to require the recall of commercialized products under certain circumstances.

A government‑mandated or voluntary recall by us could occur as a result of an unacceptable risk to health, component failures, malfunctions, manufacturing defects, labeling or design deficiencies, packaging defects, or other deficiencies, or failures to comply with applicable regulations. If we do not adequately address problems associated with our devices, we may face additional regulatory requirements or enforcement action, including required new marketing authorizations, FDA warning letters, product seizure, injunctions, administrative penalties, or civil or criminal proceedings.

We may initiate voluntary withdrawals, removals, or corrections for our products in the future that we determine do not require notification of FDA. If FDA disagrees with our determinations, it could require us to report those actions and we may be subject to enforcement action. A future recall announcement or other corrective action could harm our financial results and reputation, potentially lead to product liability claims against us, require the dedication of our time and capital, and negatively affect our sales.

In addition, FDA’s and other regulatory authorities’ policies may change, and additional government regulations may be enacted that could prevent, limit, or delay regulatory approval of our product candidates. For example, in November 2018, FDA announced that it plans to develop proposals to drive manufacturers utilizing the 510(k) pathway toward the use of newer predicates. It is unclear the extent to which any proposals, if adopted, could impose additional regulatory requirements on us that could delay our ability to obtain new 510(k) clearances, increase the costs of compliance, or restrict our ability to maintain our current clearances.

44

We also cannot predict the likelihood, nature, or extent of government regulation that may arise from future legislation or administrative or executive action, either in the U.S. or abroad. For example, the Trump Administration previously enacted several executive actions that could impose significant burdens on, or otherwise materially delay, FDA’s ability to engage in routine regulatory and oversight activities. It is difficult to predict how these executive actions and executive actions that may be taken under the Biden Administration may affect FDA’s ability to exercise its regulatory authority. If these executive actions impose constraints on FDA’s ability to engage in oversight and implementation activities in the normal course, our business may be negatively impacted.

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.

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, including certain federal and state healthcare laws and regulations pertaining to fraud and abuse, such as anti‑kickback, self‑referral, false claims, and consumer protection laws.

Further, the healthcare industry has changed significantly over time, and we expect the industry to continue to evolve. By way of example, in response to perceived increases in health care costs, the Affordable Care Act was signed into law in March 2010, which, among other things, contained certain provisions designed to generate the revenues necessary to fund the healthcare coverage expansions provided for therein. The law has been subject to continuous legislative and regulatory changes and court challenges, with dissenting U.S. Supreme Court judges even asserting it is unconstitutional in June of 2021. On January 28, 2021, President Biden issued an executive order to initiate a special enrollment period from February 15, 2021 through May 15, 2021 for purposes of obtaining health insurance coverage through the Affordable Care Act marketplace. The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the Affordable Care Act. It is unclear how other such litigation and the healthcare reform measures of the Biden administration will impact the Affordable Care Act. The healthcare market itself is highly regulated and subject to changing political, economic, and regulatory influences. 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. If we or our operations are found to be in violation of any of these laws and regulations, we may be subject to penalties that could materially adversely affect our business, results of operations, and financial condition.

Changes in internet regulations could adversely affect our business.

Laws, rules, and regulations governing internet communications, advertising, and e‑commerce are dynamic, and the extent of future government regulation is uncertain. Federal and state regulations govern various aspects of our online business, including intellectual property ownership and infringement, trade secrets, the distribution of electronic communications, marketing and advertising, user privacy and data security, search engines, and internet tracking technologies. Future taxation on the use of the internet or e‑commerce transactions could also be imposed. Existing or future regulation or taxation could increase our operating expenses and expose us to significant liabilities.

Disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire, retain or deploy key leadership and other personnel, or otherwise prevent new or modified products from being developed, cleared or approved or commercialized in a timely manner or at all, which could negatively impact our business.

The ability of the FDA to review and clear or approve new products can be affected by a variety of factors, including government budget and funding levels, statutory, regulatory, and policy changes, the FDA’s ability to hire and retain key personnel and accept the payment of user fees, and other events that may otherwise affect the FDA’s ability to perform routine functions. Average review times at the FDA have fluctuated in recent years as a result. In addition, government funding of other government agencies that fund research and development activities is subject to the political process, which

45

is inherently fluid and unpredictable. Disruptions at the FDA and other agencies may also slow the time necessary for new medical devices or modifications to cleared or approved medical devices to be reviewed and/or cleared or approved by necessary government agencies, which could adversely affect our business. For example, over the last several years, including for 35 days beginning on December 22, 2018, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical FDA employees and stop critical activities.

Separately, in response to the COVID‑19 pandemic, on March 10, 2020 the FDA announced its intention to postpone most inspections of foreign manufacturing facilities and products, and on March 18, 2020, the FDA temporarily postponed routine surveillance inspections of domestic manufacturing facilities. Subsequently, on July 10, 2020 the FDA announced its intention to resume certain on‑site inspections of domestic manufacturing facilities subject to a risk‑based prioritization system. The FDA intends to use this risk‑based assessment system to identify the categories of regulatory activity that can occur within a given geographic area, ranging from mission critical inspections to resumption of all regulatory activities. Regulatory authorities outside the United States may adopt similar restrictions or other policy measures in response to the COVID‑19 pandemic. If a prolonged government shutdown occurs, or if global health concerns continue to prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities, it could significantly impact the ability of the FDA or other regulatory authorities to timely review and process our regulatory submissions, which could have a material adverse effect on our business.

We are subject to data privacy and security laws and regulations governing our collection, use, disclosure, and storage of personally identifiable information, including personal health information, which may impose restrictions on us and our operations and subject us to penalties if we are unable to fully comply with such laws.

In order to provide our products and services, we routinely receive, process, transmit, and store PII, including personal health information, of individuals, as well as other financial, confidential, and proprietary information belonging to our members and third parties from which we obtain information (e.g., private insurance companies, financial institutions, etc.). The receipt, maintenance, protection, use, transmission, disclosure, and disposal of this information is regulated at the federal, state, international, and industry levels, and we may also have obligations with respect to this information pursuant to our contractual requirements. These laws, rules, and requirements are subject to frequent change. Compliance with new privacy and security laws, regulations, and requirements may result in increased operating costs and may constrain or require us to alter our business model or operations.

These laws and regulations include the Health Information Portability and Accountability Act of 1996, as amended by the HITECH, and their implementing regulations (referred to collectively as “HIPAA”). Among other requirements, HIPAA establishes privacy and security standards for the protection of PHI by health plans, healthcare clearinghouses, and certain healthcare providers, referred to as covered entities, which includes us, and the business associates with whom such covered entities contract for services. HIPAA imposes mandatory penalties for certain violations. Penalties will vary significantly depending on factors such as the date of the violation, whether the covered entity or business associate knew or should have known of the failure to comply, or whether the failure to comply was due to willful neglect. HIPAA also authorizes state attorneys general to file suit on behalf of their residents. Courts are able to award damages, costs, and attorneys’ fees related to violations of HIPAA in such cases, and HIPAA standards have been used as the basis for duty of care claims in state civil suits, such as those for negligence or recklessness in the misuse or breach of PHI. In addition, HIPAA mandates that the HHS conduct periodic compliance audits of HIPAA covered entities or business associates for compliance with the HIPAA Privacy and Security Standards. HIPAA requires notification to affected individuals and HHS, and in certain cases media outlets, for unauthorized acquisition, access, use, or disclosure of PHI, with certain exceptions related to unintentional or inadvertent use or disclosure by employees or authorized individuals.

We have members throughout all 50 states, and our solutions may contain healthcare information of customers located across all 50 states. Therefore, we may be subject to the privacy laws of each such state, which vary from state to state and, in some cases, can impose more restrictive requirements than federal law, such as the California Consumer Privacy Act (“CCPA”) which went into effect in January 2020 and provides for enhanced consumer protections for California residents and statutory fines for data security breaches or other CCPA violations. Additionally, California voters approved the California Privacy Rights Act (“CPRA”) on November 3, 2020, which will amend and expand the CCPA, including by

46

providing consumers with additional rights with respect to their personal data. The CPRA will come into effect on January 1, 2023, applying to information collected by businesses on or after January 1, 2022. The interplay of federal and state laws may be subject to varying interpretations by courts and government agencies, creating complex compliance issues for us and potentially exposing us to additional expense, adverse publicity, and liability. Further, as regulatory focus on privacy issues continues to increase and laws and regulations concerning the protection of personal information are proposed, enacted, or expanded or become more complex, the risks to our business could intensify. Changes in laws or regulations associated with the enhanced protection of certain types of sensitive data, such as PHI or PII, along with increased member demands for enhanced data security infrastructure, could greatly increase our cost of providing our products or services, decrease demand for our products or services, reduce our revenue, and/or subject us to additional liabilities.

We are also subject to PIPEDA and similar provincial laws in Canada. PIPEDA is the federal privacy law for private‑sector organizations. It sets out the ground rules for how businesses must handle personal information in the course of commercial activity. Under PIPEDA, we must obtain an individual’s consent when we collect, use, or disclose that individual’s personal information. Individuals have the right to access and challenge the accuracy of their personal information held by an organization, and personal information may only be used for the purposes for which it was collected. If an organization intends to use personal information for another purpose, it must again obtain that individual’s consent. Failure to comply with PIPEDA could result in significant fines and penalties or possible damage awards for the tort of public humiliation.

As we have expanded internationally, we are also subject to additional privacy rules, many of which, such as GDPR are significantly more stringent than those in the U.S. We also cannot determine the impact that future laws, regulations and standards may have on our business. Complying with these evolving obligations is costly, and any failure to comply could give rise to unwanted media attention and other negative publicity, damage our member and consumer relationships and reputation, and result in lost sales, fines, or lawsuits.

Noncompliance or findings of noncompliance with applicable laws, regulations, or requirements, or the occurrence of any privacy or security breach involving the misappropriation, loss, or other unauthorized disclosure of sensitive personal information, whether by us or by one of our third party service providers, could have a material adverse effect on our reputation and business, including, among other consequences, mandatory disclosure to the media, loss of existing or new members, significant increases in the cost of managing and remediating privacy or security incidents, and material fines, penalties, and litigation awards, any of which could have a material adverse effect on our business, results of operations, and financial condition.

We obtain and process a large amount of sensitive data. Our systems and networks may be subject to cybersecurity breaches and other disruptions that could compromise our information. Any real or perceived improper use of, disclosure of, or access to such data could harm our reputation and have a material adverse effect on our business, results of operations, and financial condition.

We use, obtain, and process large amounts of confidential, sensitive, and proprietary data, including PHI subject to HIPAA and PII subject to state and federal privacy, security, and breach notification laws. The secure processing and maintenance of this information is critical to our operations and business strategy. If our or our members’ confidential information is lost, improperly disclosed, or threatened to be disclosed, our insurance may not protect us from these risks.

Our website and information systems may be subject to computer viruses, break ins, phishing impersonation attacks, attempts to overload our servers with denial of service or other attacks, ransomware, and similar incidents or disruptions from unauthorized use of our computer systems, as well as unintentional incidents, including employee or system error, causing data leakage, any of which could lead to interruptions, delays, or website shutdowns, or could cause loss of critical data or the unauthorized disclosure, access, acquisition, alteration, or use of personal or other confidential information. It is critical that our facilities and infrastructure remain secure and are also perceived by the marketplace and our members to be secure. 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 members’ expectations regarding the security of healthcare information, we could incur significant liability and be subject to regulatory scrutiny and penalties 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. We could be forced to expend significant resources investigating the cause of the incident, repairing system damage, increasing cybersecurity protection, and notifying and providing credit monitoring to affected individuals. Concerns over our privacy practices could adversely affect others’ perception of us and deter members, advertisers, and partners from using our products. All of this could increase our expenses and divert the attention of our management and key personnel away from our business operations. Member care could suffer, and we could be liable if our systems fail to deliver correct information in a timely manner. Our insurance may not protect us from these risks.

For example, we experienced a systems outage that was caused by a cybersecurity incident on April 14, 2021. We promptly implemented a series of containment and remediation measures to address the incident, including temporarily isolating and shutting down affected systems and related manufacturing operations. We immediately mobilized our internal engineering security team and engaged leading forensic information technology firms to assist our investigation into the incident. Since the date of the incident, we have been actively managing the incident and, in consultation with our third-party advisors, investigating and seeking to understand and quantify the impact on the Company, our business operations and financial results. While the Company had no data loss from, or other loss of assets as a result of, the incident, including any exposure of customer or team member information, there is no guarantee that such loss will not occur in any future incident. The incident caused delays and disruptions to parts of our business, including treatment planning, manufacturing operations, and product delivery. While we maintain insurance coverage for certain expenses and potential liabilities that may be associated with this incident, and we plan to pursue coverage for all applicable expenses and liabilities, disputes over the extent of insurance coverage for claims are not uncommon, and there is no guarantee we will recognize any proceeds resulting from our claim. Furthermore, while we have not been the subject of any legal proceedings involving this incident, it is possible that we could be the subject of claims from persons alleging that they suffered damages from the incident. We also are in the process of implementing a variety of measures to further enhance our cybersecurity protections and minimize the impact of any future attack. However, cyber threats are constantly evolving, and there can be no guarantee that a future cyber event will not occur.

We are subject to consumer protection laws that regulate our marketing practices and prohibit unfair or deceptive acts or practices. Our actual or perceived failure to comply with such obligations could harm our business, and changes in such regulations or laws could require us to modify our products, marketing or advertising efforts.

In connection with the marketing or advertisement of our products and services, we could be, and occasionally are, the target of claims relating to false, misleading, deceptive, or otherwise noncompliant advertising or marketing practices, including under the auspices of the Federal Trade Commission (the “FTC”), state consumer protection statutes, and the Australian Competition and Consumer Commission (the “ACCC”). If we rely on third parties to provide any marketing and advertising of our products and services, we could be liable for, or face reputational harm as a result of, their marketing practices if, for example, they fail to comply with applicable statutory and regulatory requirements.

If we are found to have breached any consumer protection, advertising, unfair competition, or other laws or regulations, we may be subject to enforcement actions that require us to change our marketing and business practices in a manner which may negatively impact us. This could also result in litigation, fines, penalties, and adverse publicity that could cause reputational harm and loss of member trust, which could have an adverse effect on our business.

We are subject to a number of risks related to the credit card and debit card payments we accept.

We accept payments through credit and debit card transactions. For credit and debit card payments, we pay interchange and other fees, which may increase over time. An increase in those fees may require us to increase the prices we charge and would increase our operating expenses, either of which could harm our business, results of operations, and financial condition.

If we or our processing vendors fail to maintain adequate systems for the authorization and processing of credit and debit card transactions, it could cause one or more of the major credit card companies to disallow our continued use of their

48

payment products. In addition, if these systems fail to work properly and, as a result, we do not charge our members’ credit or debit cards on a timely basis or at all, our business, revenue, results of operations, and financial condition could be harmed.

The payment methods that we offer also subject us to potential fraud and theft by criminals, who are becoming increasingly more sophisticated in exploiting weaknesses that may exist in the payment systems. If we fail to comply with applicable rules or requirements for the payment methods we accept, or if payment‑related data is compromised due to a breach, we may be liable for significant costs incurred by payment card issuing banks and other third parties or subject to fines and higher transaction fees, or our ability to accept or facilitate certain types of payments may be impaired. In addition, our members could lose confidence in certain payment types, which may result in a shift to other payment types or potential changes to our payment systems that may result in higher costs. If we fail to adequately control fraudulent credit card transactions, we may face civil liability, diminished public perception of our security measures, and significantly higher card‑related costs, each of which could harm our business, results of operations, and financial condition.

We are also subject to payment card association operating rules, certification requirements, and rules governing electronic funds transfers, which could change or be reinterpreted to make it more difficult for us to comply. We are required to comply with payment card industry security standards. Failing to comply with those standards may violate payment card association operating rules, federal and state laws and regulations, and the terms of our contracts with payment processors. Any failure to comply fully also may subject us to fines, penalties, damages, and civil liability, and may result in the loss of our ability to accept credit and debit card payments. Further, there is no guarantee that such compliance will prevent illegal or improper use of our payment systems or the theft, loss, or misuse of data pertaining to credit and debit cards, card holders, and transactions.

If we are unable to maintain our chargeback rate or refund rates at acceptable levels, our processing vendor may increase our transaction fees or terminate its relationship with us. Any increases in our credit and debit card fees could harm our results of operations, particularly if we elect not to raise our rates for our products and services to offset the increase. The termination of our ability to process payments on any major credit or debit card would significantly impair our ability to operate our business.

Issues related to the quality and safety of our products, raw materials, or packaging could cause a product recall or discontinuation or litigation, resulting in harm to our reputation and negatively impacting our business, results of operations, and financial condition.

Medical devices involve an inherent risk of product liability claims and associated adverse publicity. Our products generally maintain a good reputation with members, but issues related to quality and safety of products, raw materials, or packaging could jeopardize our image and reputation. We have received negative publicity related to these types of concerns, while we do not believe this publicity to be accurate characterizations of our products, or our members’ view of our products, this might negatively impact demand for our products, cause production and delivery disruptions, or impact our stock price. We may need to recall or discontinue products if they become unfit for use. In addition, we could potentially be subject to litigation or government action, which could result in payment of fines or damages. 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. Also, other types of claims asserted against us may not be covered by insurance. A successful claim brought against us in excess of available insurance, or another type of claim which is uninsured or that results in significant adverse publicity against us, could harm our business, results of operations, and financial condition. Any claim, regardless of its merit or eventual outcome, could result in significant legal defense costs. 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. Cost associated with these potential actions could negatively affect our business, results of operations, and financial condition.

49

We face risks related to our international sales, including the need to obtain necessary foreign regulatory clearance or approvals.

Sales of our products outside the U.S. will subject us to foreign regulatory requirements that vary widely from country to country. The time required to obtain clearances or approvals required by other countries may be longer than that required for FDA clearance or approval, and requirements for such approvals may differ from FDA requirements. We may be unable to obtain regulatory approvals and may also incur significant costs in attempting to obtain foreign regulatory approvals or maintain those we already have, including in Canada, Australia, the U.K., Ireland, France, and the E.U. If we experience delays in receipt of approvals to market our products in new jurisdictions, or if we fail to receive these approvals, we may be unable to market our products in international markets in a timely manner, if at all, which could materially impact our international expansion and adversely affect our business as a whole. In addition, we anticipate that regulations in certain foreign countries may challenge our teledentistry model. Some international regulations may also limit the availability of SmilePay to members in certain jurisdictions without our first obtaining a license or engaging a third party to provide such financing, or limit the financing options we can offer our members. If any of these risks were to materialize, they could limit our expected international growth and profitability.

Risks Related to our Common Stock

We are a “controlled company” within the meaning of the corporate governance standards of NASDAQ. As a result, we qualify for, and rely on, exemptions from certain corporate governance standards.

Pursuant to the Voting Agreement, David Katzman, our Chairman and Chief Executive Officer, controls a majority of the voting power of shares eligible to vote in the election of our directors. Because more than 50% of the voting power in the election of our directors is held by an individual, group, or another company, we are a “controlled company” within the meaning of the corporate governance standards of NASDAQ. As a controlled company, we have elected not to comply with certain corporate governance requirements, including the requirements that, within one year of the date of the listing of our Class A common stock:

•a majority of our board of directors consists of “independent directors,” as defined under the rules of such exchange;

•our board of directors has a compensation committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities; and

•our board of directors has a nominating and corporate governance committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities.

The majority of our directors are not independent and, other than the audit committee, our board committees are not composed entirely of independent directors. Accordingly, our stockholders do not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance requirements of NASDAQ.

We incur increased costs and are subject to additional regulations and requirements as a result of being a public company, which could lower our profits or make it more difficult to run our business.

As a public company, we incur significant legal, accounting, and other expenses that we did not incur as a private company, including costs associated with public company reporting requirements. We also incur costs associated with the Sarbanes‑Oxley Act, and related rules implemented by the SEC and NASDAQ. The expenses generally for reporting and corporate governance purposes increase our legal and financial compliance costs and make some activities more time‑consuming and costly. Furthermore, if we are unable to satisfy our obligations as a public company, we could be subject to delisting of our Class A common stock, fines, sanctions, other regulatory action, and potentially civil litigation.

50

If we are unable to maintain effective internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports and the market price of our Class A common stock may decline.

We are required to maintain internal control over financial reporting, report any material weaknesses in such internal controls, and furnish a report by management on the effectiveness of our internal control over financial reporting, pursuant to Section 404 of the Sarbanes‑Oxley Act. The process of designing, implementing, and testing the internal control over financial reporting required to comply with this obligation is time consuming, costly, and complicated. If we identify material weaknesses in our internal control over financial reporting, if we are unable to comply with the requirements of Section 404 of the Sarbanes‑Oxley Act in a timely manner, or if we are unable to assert that our internal control over financial reporting is effective, investors may lose confidence in the accuracy and completeness of our financial reports and the market price of our Class A common stock could decline, and we could also become subject to investigations by the stock exchange on which our Class A common stock is listed, the SEC, or other regulatory authorities, which could require additional financial and management resources.

The trading price of shares of our Class A common stock has declined significantly since our initial public offering and may continue to be volatile.

The market price of our Class A common stock has declined significantly since our initial public offering and may continue to be highly volatile and subject to wide fluctuations. Securities markets worldwide experience significant price and volume fluctuations. This market volatility, as well as general economic, market, or political conditions, could reduce the market price of shares of our Class A common stock regardless of our operating performance. The market price of shares of our Class A common stock may be affected by a number of potential factors, including variations in our quarterly operating results or dividends, if any, to stockholders, adverse publicity surrounding our business, additions or departures of key management personnel, failure to meet analysts’ earnings estimates, publication of research reports about us and our industry, litigation and government investigations, changes or proposed changes in laws or regulations or differing interpretations or enforcement thereof affecting our business, adverse market reaction to any indebtedness we may incur or securities we may issue in the future, changes in market valuations of similar companies or speculation in the press or investment community, announcements by our competitors of significant contracts, acquisitions, dispositions, strategic partnerships, joint ventures, or capital commitments, adverse publicity about the industries we participate in, or individual scandals.

In the past few years, stock markets have experienced extreme price and volume fluctuations. In the past, following periods of volatility in the overall market and the market price of a company’s securities, securities class action litigation has often been instituted against these companies. Such litigation could result in substantial costs and diversion of our management’s attention and resources. See “We are the subject of purported class action lawsuits, and additional litigation may be brought against us in the future.”

We have no current plans to pay cash dividends on our Class A common stock; as a result, our stockholders may not receive any return on investment unless our stockholders sell their Class A common stock for a price greater than that which they paid for it.

We have no current plans to pay dividends on our Class A common stock. Any future determination to pay dividends will be made at the discretion of our board of directors, subject to applicable laws, and will depend on a number of factors, including our financial condition, results of operations, capital requirements, contractual, legal, tax and regulatory restrictions, general business conditions, and other factors that our board of directors may deem relevant. In addition, our ability to pay cash dividends may be restricted by the terms of any of our future debt financing arrangements, which may contain terms restricting or limiting the amount of dividends that may be declared or paid on our common stock. As a result, our stockholders may not receive any return on an investment in our Class A common stock unless they sell their Class A common stock for a price greater than that which they paid for it.

51

If our operating and financial performance in any given period does not meet the guidance that we provide to the public, the market price of our Class A common stock may decline.

We may, but are not obligated to, provide public guidance on our expected operating and financial results for future periods. Any such guidance will be comprised of forward‑looking statements subject to the risks and uncertainties described in our public filings and public statements. Our actual results may not always be in line with or exceed any guidance we have provided, especially in times of economic uncertainty. If, in the future, our operating or financial results for a particular period do not meet any guidance we provide or the expectations of investment analysts, or if we reduce our guidance for future periods, the market price of our Class A common stock may decline. Even if we do issue public guidance, there can be no assurance that we will continue to do so in the future.

If securities or industry analysts cease to publish research or reports about our business, or publish negative reports, the market price of our Class A common stock could decline.

The trading market for our Class A common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause the market price or trading volume of our Class A common stock to decline. Moreover, if one or more of the analysts who cover us downgrades our Class A common stock, or if our reporting results do not meet their expectations, the market price of our Class A common stock could decline. Some securities analysts have downgraded our Class A common stock since our initial public offering.

The dual‑class structure of our common stock may adversely affect the trading market for our Class A Shares.

S&P Dow Jones’ criteria for inclusion of shares of public companies on certain indices, including the S&P 500, excludes companies with multiple classes of shares from being added to such indices. In addition, several shareholder advisory firms have announced their opposition to the use of multiple class structures. As a result, the dual class structure of our common stock may prevent the inclusion of our Class A common stock in such indices and may cause shareholder advisory firms to publish negative commentary about our corporate governance practices or otherwise seek to cause us to change our capital structure. Any exclusion from such indices could result in a less active trading market for our Class A common stock. Any actions or publications by shareholder advisory firms critical of our corporate governance practices or capital structure could also adversely affect the value of our Class A common stock.

If we or the Pre‑IPO investors sell substantial amounts of shares of our Class A common stock, the market price of our Class A common stock could decline.

The sale of a substantial number of shares of our Class A common stock in the public market, or the perception that such sales could occur could adversely affect the prevailing market price of shares of our Class A common stock. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price we deem appropriate. In addition, subject to certain limitations and exceptions, pursuant to certain provisions of the SDC Financial LLC Agreement, the holders of LLC Units following the consummation of our initial public offering and the reorganization transactions in connection with our initial public offering (“Continuing LLC Member”) may exchange LLC Units (with automatic cancellation of an equal number of shares of Class B common stock) for shares of our Class A common stock on a one‑for‑one basis, subject to customary adjustments for certain subdivisions (stock splits), combinations, or purchases of Class A common stock. All of the LLC Units and shares of Class B common stock are exchangeable for shares of our Class A common stock.

Each of our directors and officers, and substantially all of our Pre‑IPO investors, entered into lock‑up agreements with the underwriters of our initial public offering that restricted their ability to sell or transfer their shares of Class A common stock. This agreement expired on March 9, 2020.

52

In addition, on September 16, 2019, we filed a registration statement on Form S‑8 under the Securities Act to register 44,259,239 shares of our Class A common stock or securities convertible into or exchangeable for shares of our Class A common stock that may be issued from time to time pursuant to our Omnibus Plan and SPP. Accordingly, shares of Class A common stock registered under such registration statement if, when, and to the extent issued under these plans, will be available for sale in the open market.

We are party to a Registration Rights Agreement with Pre‑IPO investors, whereby, following the initial public offering and the expiration of the related 180‑day lock‑up period, we may be required to register under the Securities Act the sale of shares of our Class A common stock held by Pre‑IPO investors, including shares that may be issued to Continuing LLC Members upon exchange of their LLC Units. Shares of Class A common stock registered pursuant to the Registration Rights Agreement will also be available for sale in the open market upon such registration unless restrictions apply.

As restrictions on resale end, the market price of our Class A common stock could drop significantly if the holders of these restricted shares sell them or are perceived by the market as intending to sell them. These factors could also make it more difficult for us to raise additional funds through future offerings of our common stock or other securities.

Risks Related to our Organization and Structure

Pursuant to the Voting Agreement, David Katzman, our Chairman and Chief Executive Officer, controls a majority of the voting power of shares of our common stock eligible to vote in the election of our directors and on other matters submitted to a vote of our stockholders, and his interests may conflict with ours or our stockholders’ in the future.

Holders of our Class A common stock and our Class B common stock vote together as a single class on all matters (including the election of directors) submitted to a vote of stockholders, with each share of Class A common stock entitling the holder to one vote and each share of Class B common stock entitling the holder to ten votes. Certain trusts affiliated with David Katzman, our Chairman and Chief Executive Officer, Steven Katzman, our Chief Operating Officer, Jordan Katzman and Alexander Fenkell, our co‑founders, and certain of their affiliated trusts and entities (collectively, the “Voting Group”) are party to a Voting Agreement (the “Voting Agreement”), pursuant to which the Voting Group has given David Katzman, sole voting, but not dispositive, power over the shares of our Class B common stock beneficially owned by the Voting Group. Accordingly, pursuant to the Voting Agreement, David Katzman controls a majority of the voting power of shares of our common stock eligible to vote in the election of our directors and on other matters submitted to a vote of our stockholders. So long as 9.4% of shares of Class B common stock remain outstanding, the holders of our Class B common stock will be able to control the outcome of matters submitted to a stockholder vote. Even when the Voting Group ceases to own shares of our common stock representing a majority of the total voting power, for so long as the Voting Group continues to own a significant percentage of our common stock, David Katzman, through his voting power, will still be able to significantly influence the composition of our board of directors and the approval of actions requiring stockholder approval. Accordingly, for such period of time, David Katzman will have significant influence with respect to our management, business plans, and policies, including the appointment and removal of our officers. In particular, until the earlier of (i) the ten‑year anniversary of the consummation of our initial public offering or (ii) the date on which the shares of Class B common stock held by the Voting Group and their permitted transferees represent less than 15% of the Class B common stock held by the Voting Group and their permitted transferees as of immediately following the consummation of our initial public offering, David Katzman will be able to cause or prevent a change of control of us or a change in the composition of our board of directors and could preclude any unsolicited acquisition of us. The concentration of voting power could deprive stockholders of an opportunity to receive a premium for their shares of Class A common stock as part of a sale of us and ultimately might affect the market price of our Class A common stock.

David Katzman and Camelot Venture Group (“Camelot”), with which he and certain other members of the Voting Group are affiliated, engage in a broad spectrum of activities. While the SDC Financial LLC Agreement restricts the Continuing LLC Members from engaging in certain competing business activities, David Katzman and Camelot may engage in activities where their interests conflict with our interests or those of our stockholders.

53

We are a holding company. Our sole material asset is our equity interest in SDC Financial, and as such, we depend on our subsidiaries for cash to fund all of our expenses, including taxes and payments under the Tax Receivable Agreement.

We are a holding company and have no material assets other than our ownership of LLC Units. Our ability to pay cash dividends will depend on the payment of distributions by our current and future subsidiaries, including SDC Financial, SDC LLC and SDC Holding, and such distributions may be restricted as a result of regulatory restrictions, state law regarding distributions by a limited liability company to its members, or contractual agreements, including any future agreements governing their indebtedness.

SDC Financial is treated as a flow‑through entity for U.S. federal income tax purposes and, as such, generally is not subject to U.S. federal income tax. Instead, taxable income will be allocated to holders of LLC Units, including us. Accordingly, we will incur income taxes on our allocable share of any net taxable income of SDC Financial and will also incur expenses related to our operations. Subject to having available cash and subject to limitations imposed by applicable law and contractual restrictions (including pursuant to our debt instruments), the SDC Financial LLC Agreement requires SDC Financial to make certain distributions to us and the Continuing LLC Members, calculated using an assumed tax rate, to facilitate the payment of taxes with respect to the income of SDC Financial that is allocated to us and them. We also incur expenses related to our operations and will cause SDC Financial to make distributions or, in the case of certain expenses, payments in an amount sufficient to allow us to pay our taxes and operating expenses and to fund our payment of amounts due under the Tax Receivable Agreement. Because tax distributions are based on an assumed tax rate, SDC Financial may be required to make tax distributions that, in the aggregate, exceed the amount of taxes that SDC Financial would have paid if it were itself taxed on its net income. SDC Financial’s ability to make such distributions may be subject to various limitations and restrictions. If we do not have sufficient funds to pay tax or other liabilities or to fund our operations (as a result of SDC Financial’s inability to make distributions due to various limitations and restrictions or as a result of the acceleration of our obligations under the Tax Receivable Agreement), we may have to borrow funds, and our liquidity and financial condition could be materially and adversely affected. To the extent that we are unable to make payments under the Tax Receivable Agreement for any reason, such payments will be deferred and will accrue interest.

SDC Financial may make distributions of cash to us substantially in excess of the amounts we use to make distributions to our stockholders and pay our expenses (including our taxes and payments under the Tax Receivable Agreement). To the extent we do not distribute such excess cash as dividends on our Class A common stock, the Continuing LLC Members would benefit from any value attributable to such cash as a result of their ownership of Class A common stock upon an exchange or redemption of their LLC Units.

We will receive a portion of any distributions made by SDC Financial. Any cash received from such distributions will first be used by us to satisfy any tax liability and then to make any payments required under the Tax Receivable Agreement. Subject to having available cash and subject to limitations imposed by applicable law and contractual restrictions (including pursuant to our debt instruments), the SDC Financial LLC Agreement requires SDC Financial to make certain distributions to us and the Continuing LLC Members, pro rata, to facilitate the payment of taxes with respect to the income of SDC Financial that is allocated to us and them. To the extent that the tax distributions we receive exceed the amounts we actually require to pay taxes, Tax Receivable Agreement payments, and other expenses, we will not be required to distribute such excess cash. Our board of directors may, in its sole discretion, choose to use such excess cash for any purpose, including (i) to make distributions to the holders of our Class A common stock, (ii) to acquire additional newly issued LLC Units, and/or (iii) to repurchase outstanding shares of our Class A common stock. Unless and until our board of directors chooses, in its sole discretion, to declare a distribution, we will have no obligation to distribute such cash (or other available cash other than any declared dividend) to our stockholders.

No adjustments to the redemption or exchange ratio of LLC Units for shares of our Class A common stock will be made as a result of either (i) any cash distribution by us or (ii) any cash that we retain and do not distribute to our stockholders. To the extent we do not distribute such cash as dividends on our Class A common stock and instead, for example, hold such cash balances, buy additional LLC Units or lend them to SDC Financial, this may result in shares of our Class A common stock increasing in value relative to the LLC Units. The holders of LLC Units may benefit from any value attributable to such cash balances if they acquire shares of Class A common stock in exchange for their LLC Units or if we acquire additional LLC

54

Units (whether from SDC Financial or from holders of LLC Units) at a price based on the market price of our Class A common stock at the time.

Pursuant to the Tax Receivable Agreement, we will be required to pay the Continuing LLC Members for certain tax benefits we may claim as a result of the tax basis step‑up we received in connection with our initial public offering, as well as subsequent exchanges of LLC Units for shares of Class A common stock or cash. In certain circumstances, payments under the Tax Receivable Agreement may be accelerated and/or significantly exceed the actual tax benefits we realize.

Our purchase of LLC Units from SDC Financial, coupled with SDC Financial’s purchase and cancellation of LLC Units from the Pre‑IPO investors in connection with the IPO and any future exchanges of LLC Units for our Class A common stock or cash, resulted and are expected in the future to result in increases in our allocable tax basis in the assets of SDC Financial that otherwise would not have been available to us. These increases in tax basis are expected to reduce the amount of cash tax that we would otherwise have to pay in the future due to increases in depreciation and amortization deductions (for tax purposes). These increases in tax basis may also decrease gain (or increase loss) on future dispositions of certain assets of SDC Financial to the extent the increased tax basis is allocated to those assets. The Internal Revenue Service (“IRS”) may challenge all or part of these tax basis increases, and a court could sustain such a challenge.

We and SDC Financial entered into the Tax Receivable Agreement, pursuant to which SmileDirectClub, Inc. (“SDC Inc.”) agreed to pay the Continuing LLC Members 85% of the cash savings, if any, in U.S. federal, state, and local income tax or franchise tax that SDC Inc. actually realizes as a result of (a) the increases in tax basis attributable to exchanges by Continuing LLC Members and (b) tax benefits related to imputed interest deemed to be paid by SDC Inc. as a result of the Tax Receivable Agreement. While the actual increase in tax basis, as well as the actual amount and timing of any payments under the Tax Receivable Agreement, will vary depending upon a number of factors, including the timing of exchanges, the price of shares of our Class A common stock at the time of the exchange, the extent to which such exchanges are taxable, future tax rates, and the amount and timing of our income, we expect that, as a result of the size of the increases in the tax basis of the tangible and intangible assets of SDC Financial attributable to our interests in SDC Financial, during the expected term of the Tax Receivable Agreement, the payments that we may make to the Continuing LLC Members could be substantial.

The payment obligation under the Tax Receivable Agreement is our obligation and not an obligation of SDC Financial. In addition, the Continuing LLC Members will not reimburse us for any payments previously made under the Tax Receivable Agreement if such basis increases or other benefits are subsequently disallowed, although excess payments made to any Continuing LLC Member may be netted against payments otherwise to be made, if any, to the relevant Continuing LLC Member after our determination of such excess. However, a challenge to any tax benefits initially claimed by us may not arise for a number of years following the initial time of such payment or, even if challenged early, such excess cash payment may be greater than the amount of future cash payments that we might otherwise be required to make under the terms of the Tax Receivable Agreement and, as a result, there might not be future cash payments from which to net against. The applicable U.S. federal income tax rules are complex and factual in nature, and there can be no assurance that the IRS or a court will not disagree with our tax reporting positions. As a result, in certain circumstances we may make payments to the Continuing LLC Members under the Tax Receivable Agreement in excess of our actual cash tax savings. Our ability to achieve benefits from any tax basis increase, and the payments to be made under the Tax Receivable Agreement, will depend upon a number of factors, as discussed above, including the timing and amount of our future income.

In addition, the Tax Receivable Agreement provides that, upon a merger, asset sale or other form of business combination or certain other changes of control, a material breach of our obligations under the Tax Receivable Agreement or if, at any time, we elect an early termination of the Tax Receivable Agreement, our (or our successor’s) obligations with respect to exchanged or acquired LLC Units (whether exchanged or acquired before or after such change of control or early termination) would be based on certain assumptions, including that we would have sufficient taxable income to fully utilize the deductions arising from the increased tax deductions and tax basis and other benefits related to entering into the Tax Receivable Agreement, and, in the case of certain early termination elections, that any LLC Units that have not been exchanged will be deemed exchanged for the market value of the Class A common stock at the time of termination.

55

Consequently, it is possible, in these circumstances, that the actual cash tax savings realized by us may be significantly less than the corresponding Tax Receivable Agreement payments.

Anti‑takeover provisions in our organizational documents and Delaware law might discourage or delay attempts to acquire us that stockholders might consider favorable.

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that may make the merger or acquisition of us more difficult without the approval of our board of directors. Among other things, these provisions:

•allow us to authorize the issuance of undesignated preferred stock in connection with a stockholder rights plan or otherwise, the terms of which may be established and the shares of which may be issued without stockholder approval, and which may include super voting, special approval, dividend, or other rights or preferences superior to the rights of the holders of common stock;

•preclude stockholder action by written consent at any time when the Voting Group controls, in the aggregate, less than 30% of the voting power of our stock entitled to vote generally in the election of directors, unless such action is unanimously recommended by the board;

•provide that our bylaws may be amended or repealed only by a majority vote of our board of directors or by the affirmative vote of the holders of at least 66 2/3% of the votes which all our stockholders would be entitled to cast in any annual election of directors; and

•establish advance notice requirements for nominations for elections to our board or for proposing matters that can be acted upon by stockholders at stockholder meetings.

Further, as a Delaware corporation, we are also subject to provisions of Delaware law, which may impair a takeover attempt that our stockholders may find beneficial. These anti‑takeover provisions and other provisions under Delaware law could discourage, delay, or prevent a transaction involving a change in control of us, including actions that our stockholders may deem advantageous, or could negatively affect the market price of our Class A common stock. These provisions could also discourage proxy contests and make it more difficult for stockholders to elect directors of their choosing and to cause us to take other corporate actions that stockholders desire.

Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for certain disputes with us or our directors, officers, or employees.

Our amended and restated certificate of incorporation provides that, unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for any (i) derivative action or proceeding brought on our behalf, (ii) action asserting a claim of breach of a fiduciary duty owed by any of our directors or officers to us or our stockholders, creditors, or other constituents, (iii) action asserting a claim against us or any our directors or officers arising pursuant to any provision of the Delaware General Corporation Law (“DGCL”), our amended and restated certificate of incorporation, or our amended and restated bylaws, or (iv) action asserting a claim against us or any of our directors or officers governed by the internal affairs doctrine, provided, however, that, in the event that the Court of Chancery of the State of Delaware lacks subject matter jurisdiction over any such action or proceeding, the sole and exclusive forum for such action or proceeding shall, with limited exceptions, be another state or federal court located within the State of Delaware. Any person or entity purchasing or otherwise acquiring any interest in our shares of capital stock shall be deemed to have notice of and consented to the forum provisions in our amended and restated certificate of incorporation described above. This choice of forum provision may limit a stockholder’s ability to bring claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or employees, which may discourage such lawsuits against us and our directors, officers, and employees. Alternatively, if a court were to find these provisions of our amended and restated certificate of incorporation inapplicable to, or unenforceable in respect of, one or more of the

56

specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business and financial condition.

Provisions in our organizational documents regarding exculpation and indemnification of our directors and officers may result in substantial expenditures by us and may discourage lawsuits against our directors and officers.

Our amended and restated certificate of incorporation and amended and restated bylaws, to the maximum extent permissible under Delaware law, eliminate the personal liability of our directors and officers to us and our stockholders for damages for breach of fiduciary duty. These provisions may discourage us, or our stockholders through derivative litigation, from bringing a lawsuit against any of our current or former directors or officers for any breaches of their fiduciary duties, even if such legal actions, if successful, might benefit us or our stockholders. In addition, our amended and restated certificate of incorporation and amended and restated bylaws will provide that we will, to the fullest extent permitted by Delaware law, indemnify our directors and officers for costs or damages incurred by them in connection with any threatened, pending, or completed action, suit, or proceeding brought against by reason of their positions as directors and officers. We are also party to indemnification agreements with each of our directors and executive officers and maintain directors’ and officers’ insurance. These indemnification obligations could result in our incurring substantial expenditures to cover the cost of settlement or damage awards against our directors or officers

Risks Related to the Notes

We have indebtedness in the form of convertible senior notes, which could adversely affect our financial health and our ability to respond to changes in our business.

In February 2021, we issued approximately $650.0 million principal amount of 0.00% convertible senior notes due in 2026 (the “Notes”) in a private placement offering. We also issued an additional $97.5 million aggregate principal amount of the Notes to the initial purchasers under an option granted to the initial purchasers. Our ability to repay our indebtedness, including the Notes, is significantly dependent on the generation of cash flow by our subsidiaries, as we are a holding company, and their ability to make such cash available to us, by dividend, debt repayment or otherwise.

Our indebtedness could have significant negative consequences for our security holders and our business, results of operations and financial condition by, among other things:

•increasing our vulnerability to adverse economic and industry conditions;

•limiting our ability to obtain additional financing;

•requiring the dedication of a substantial portion of our cash flow from operations to service our indebtedness, which will reduce the amount of cash available for other purposes;

•limiting our flexibility to plan for, or react to, changes in our business;

•diluting the interests of our existing stockholders as a result of issuing shares of our Class A common stock upon conversion of the notes; and

•placing us at a possible competitive disadvantage with competitors that are less leveraged than us or have better access to capital.

Our business may not generate sufficient funds, and we may otherwise be unable to maintain sufficient cash reserves, to pay amounts due under our indebtedness, including the notes, and our cash needs may increase in the future.

57

We may be unable to raise the funds necessary to repurchase the notes for cash following a fundamental change or to pay any cash amounts due upon conversion, and our other indebtedness limits our ability to repurchase the notes or pay cash upon their conversion

Noteholders may require us to repurchase their notes following a fundamental change at a cash repurchase price generally equal to the principal amount of the notes to be repurchased, plus accrued and unpaid interest, if any. In addition, upon conversion, we will satisfy part or all of our conversion obligation in cash unless we elect to settle conversions solely in shares of our Class A common stock. We may not have enough available cash or be able to obtain financing at the time we are required to repurchase the notes or pay the cash amounts due upon conversion. In addition, applicable law, regulatory authorities and the agreements governing our other indebtedness may restrict our ability to repurchase the notes or pay the cash amounts due upon conversion. Our failure to repurchase notes or to pay the cash amounts due upon conversion when required will constitute a default under the indenture. A default under the indenture or the fundamental change itself could also lead to a default under agreements governing our other indebtedness, which may result in that other indebtedness becoming immediately payable in full. We may not have sufficient funds to satisfy all amounts due under the other indebtedness and the notes.

The accounting method for the notes could adversely affect our reported financial condition and results.

The accounting method for reflecting the notes on our balance sheet, accruing interest expense for the notes and reflecting the underlying shares of our Class A common stock in our reported diluted earnings per share may adversely affect our reported earnings and financial condition.

We are subject to counterparty risk with respect to the capped call transactions, and the capped call may not operate as planned.

In connection with the pricing of the notes, we entered into privately negotiated capped call transactions with the option counterparties. The capped call transactions are expected generally to reduce the potential dilution to our Class A common stock upon any conversion of the notes and/or offset any potential cash payments we are required to make in excess of the principal amount of converted notes, as the case may be, with such reduction and/or offset subject to a cap.

The option counterparties are financial institutions, and we will be subject to the risk that they might default under the capped call transactions. Our exposure to the credit risk of the option counterparties will not be secured by any collateral. Global economic conditions have from time to time resulted in the actual or perceived failure or financial difficulties of many financial institutions, including the bankruptcy filing by Lehman Brothers Holdings Inc. and its various affiliates. If an option counterparty becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at that time under our transactions with that option counterparty. Our exposure will depend on many factors, but, generally, the increase in our exposure will be correlated with increases in the market price or the volatility of our Class A common stock. In addition, upon a default by an option counterparty, we may suffer more dilution than we currently anticipate with respect to our Class A common stock. We can provide no assurances as to the financial stability or viability of any option counterparty.

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

Our corporate headquarters are located in Nashville, Tennessee. We also lease our manufacturing facilities in Antioch, Tennessee and Columbia, Tennessee. We have 174 SmileShops across the U.S., Puerto Rico, Canada, Australia, Ireland, U.K., and France all of which are either leased or licensed from our retail partners. Lastly, we lease our facility in San Jose, Costa Rica. Management believes the terms of the leases are consistent with market standards and were arrived at through arm’s-length negotiation.

Item 3. Legal Proceedings

In the ordinary course of conducting its business, the Company is involved, from time to time, in various contractual, product liability, intellectual property, and other claims and disputes incidental to its business. Litigation is subject to many uncertainties, the outcome of individual litigated matters is not predictable with assurance, and it is reasonably possible that some of these matters may be decided unfavorably to the Company and could have a material impact on the financial statements. In addition, the Company periodically receives communications from state and federal regulatory and similar agencies inquiring about the nature of its business activities, licensing of professionals providing services, and similar matters. Such matters are routinely concluded with no financial or operational impact on the Company.

From September to December 2019, a number of purported stockholder class action complaints were filed in the U.S. District Court for the Middle District of Tennessee and in state courts in Tennessee, Michigan and New York against the Company, members of the Company’s board of directors, certain of its current and former officers, and the underwriters of its IPO. The following complaints have been filed to date: Mancour v. SmileDirectClub, Inc., 19-1169-IV (TN Chancery Court filed 9/27/19), Vang v. SmileDirectClub, Inc., 19c2316 (TN Circuit Court filed 9/30/19), Fernandez v. SmileDirectClub, Inc., 19c2371 (TN Circuit Court filed 10/4/19), Wei Wei v. SmileDirectClub, Inc., 19-1254-III (TN Chancery Court filed 10/18/19), Andre v. SmileDirectClub, Inc., 19-cv-12883 (E.D. Mich. filed 10/2/19), Ginsberg v. SmileDirectClub, Inc., 19-cv-09794 (S.D.N.Y. filed 10/23/19), Franchi v. SmileDirectClub, Inc., 19- cv-962 (M.D. Tenn. filed 10/29/19), Nurlybayev v. SmileDirectClub, Inc., 19-177527-CB (Oakland County, MI Circuit Court filed 10/30/19), Sasso v. Katzman, et al., No. 657557/2019 (NY Supreme Court filed 12/18/19), Nurlybayev v. SmileDirectClub, Inc., No. 652603/2020 (Supreme Ct. N.Y. Cty. filed June 19, 2020). The complaints all allege, among other things, that the registration statement filed with the SEC on August 16, 2019, and accompanying amendments, and the Prospectus filed with the SEC on September 13, 2019, in connection with the Company’s initial public offering were inaccurate and misleading, contained untrue statements of material facts, omitted to state other facts necessary to make the statements made not misleading, and omitted to state material facts required to be stated therein. The complaints seek unspecified money damages, other equitable relief, and attorneys’ fees and costs. All the actions are in the preliminary stages. The Company denies any alleged wrongdoing and is vigorously defending against these actions.

In December 2019, the Fernandez, Vang, Mancour and Wei Wei actions were consolidated and re-captioned In re SmileDirectClub, Inc. Securities Litigation, 19-1169-IV (Davidson County, TN Chancery Court). Plaintiffs filed a consolidated amended complaint on December 20, 2019, and Defendants moved to stay or dismiss the action on February 10, 2020. On June 4, 2020, the court denied that motion. Defendants subsequently moved for permission to seek an interlocutory appeal of that decision. On June 22, 2020, the court granted that motion. On August 3, 2020, Defendants filed an application for interlocutory appeal with the court of appeals, which was denied. On September 21, 2020, Defendants filed an application for interlocutory appeal with the Tennessee Supreme Court, which was denied. On October 2, 2020, Plaintiffs moved for class certification, which Defendants opposed on January 25, 2021. On April 28, 2021, the court ruled in favor of the Plaintiffs class certification. The Company filed its notice of appeal on May 4, 2021. That appeal is fully briefed and has been pending since oral argument on December 2, 2021. All trial court proceedings are stayed during the pendency of the appeal.

The Andre and Ginsberg actions were transferred to the U.S. District Court for the Middle District of Tennessee, where they were consolidated with the Franchi action. Plaintiffs filed a consolidated amended complaint on February 21, 2020, and Defendants moved to dismiss the action on March 23, 2020. That motion remains pending. While that motion was pending, the parties stipulated to allow Plaintiffs to file a further amended complaint, which Plaintiffs filed on March 31, 2021. Defendants’ motion to dismiss the new complaint was due on or before May 14, 2021. That motion was fully briefed as of July 19, 2021, and remains pending.

In the Nurlybayev action, on January 10, 2020, certain Defendants, including the Company, moved to be dismissed from the action for lack of personal jurisdiction and the remaining Defendants moved to dismiss or stay the entire action in favor of the related actions pending in Tennessee. On February 26, 2020, the Court granted Defendants’ motion to dismiss the entire action in favor of the related actions pending in Tennessee. On June 19, 2020, Plaintiff Nurlybayev filed a substantially

59

similar action in New York state court. On August 21, 2020, Defendants filed a motion to dismiss that action, which the Court granted on May 25, 2021. Plaintiff has filed a notice of appeal. Plaintiff perfected his appeal on January 21, 2022 and briefing on the appeal is in progress.

In the Sasso action, Plaintiff agreed to stay the action pending resolution of any motions to dismiss in any of the related actions. The Court so-ordered the parties’ stipulation to that effect on January 22, 2020.

In November and December 2019 and March 2020, three stockholder derivative actions were filed against the members of the Company’s board of directors, certain of the Company’s current and former officers and related entities: Doris Shenwick Trust v. Katzman et al., C.A. No. 2019-0940-MTZ (filed Nov. 22, 2019); Harts v. Katzman et al., C.A No. 2019-1027-MTZ (filed Dec. 23, 2019); and Sammons v. Katzman et al., C.A No. 2020-0169-MTZ (Mar. 5, 2020). The three derivative actions were consolidated into In Re SmileDirectClub, Inc. Derivative Litigation, C.A. No. 2019-0940-MTZ (Delaware Chancery Court) and Plaintiffs filed a consolidated amended complaint on April 8, 2020. The complaint alleges, among other things, that the defendants breached their fiduciary duties by allowing the Prospectus filed with the SEC on September 13, 2019, in connection with the Company's initial public offering, to contain materially misleading statements and by approving that the IPO proceeds be used to acquire Units and Common Stock from selling directors in connection with the IPO at an allegedly inflated price. The complaint also alleges that certain related entities aided and abetted the directors' alleged breach of fiduciary duties by selling their Common Stock and LLC Units and profiting from those sales. The complaint also alleges that the directors and related entities were unjustly enriched. The complaint seeks, among other things, disgorgement from the director and entity defendants. The Company denies any alleged wrongdoing and moved to dismiss the action. Briefing on the motion to dismiss was complete on November 6, 2020. A hearing on the motion to dismiss was held on February 17, 2021. The Court granted the motion to dismiss on May 28, 2021 and dismissed the complaint. On June 24, 2021, plaintiffs filed a Notice of Appeal. The parties submitted appellate briefing and on December 8, 2021, oral argument was held before the Delaware Supreme Court. On January 6, 2022, the Delaware Supreme Court affirmed dismissal of the derivative action on the basis of and for the reasons assigned by the Court of Chancery.

In September 2019, a putative class action on behalf of a consumer and three orthodontists was brought against the Company in the U.S. District Court for the Middle District of Tennessee, Ciccio, et al. v. SmileDirectClub, LLC, et al., Case No. 3:19-cv-00845 (M.D. Tenn.). The Plaintiffs assert claims for breach of warranty, false advertising under the Lanham Act, common law fraud, and various state consumer protection statutes relating to the Company’s advertising. Following a proactive voluntary dismissal by the majority of consumer plaintiffs, one consumer has since sought to rejoin the Middle District of Tennessee litigation or, in the alternative, to intervene, which the Court granted. That ruling has been appealed, and the Court stayed the consumer claims pending the appeal. On June 25, 2021, the appellate court reversed the district court and remanded with instructions to order the intervening plaintiff to mandatory binding arbitration. All remaining consumer claims remain stayed. Litigation is in the discovery stage. On October 13, 2021, the Court entered an Amended Scheduling Order, effectively staying merits discovery, and setting deadlines of March 30, 2022, to complete class certification fact discovery and September 2, 2022, to complete briefing on motions regarding class certification. The Company denies any alleged wrongdoing and intends to defend against this action vigorously.

Some state dental boards have established new rules or interpreted existing rules in a manner that limits or restricts the Company’s ability to conduct its business as currently conducted in other states or have engaged in conduct so as to otherwise interfere with the Company’s ability to conduct its business. We have filed actions in federal court in Alabama, Georgia, and California against the state dental boards in those states, alleging violations by the dental boards of various laws, including the Sherman Act and the Commerce Clause. While a national orthodontic association has filed Amicus Briefs in support of the dental boards in both the Georgia and Alabama litigations and has filed a motion to do the same in California (which motion was denied), the FTC and DOJ have filed joint Amicus Briefs in support of the Company in both the Alabama and Georgia matters. The California matter was amended, and an order of dismissal was entered on July 7, 2020. The Company filed notice of appeal on July 17, 2020, and the FTC and DOJ filed a joint Amicus Brief in support of the Company. Oral argument was held on July 26, 2021, with the FTC and DOJ arguing in support of the Company at oral argument as well. The appellate court has not yet issued its ruling. Both the Alabama and Georgia matters were then sent to the 11th Circuit Court of Appeals as a result of the dental boards in both states appealing the lower court’s decisions. Oral argument before the 11th Circuit Court of Appeals occurred in the Georgia matter on May 20, 2020, and in the Alabama matter on July 8, 2020. The

60

FTC and DOJ participated in oral arguments in support of the Company. The DOJ’s antitrust chief presented in the Alabama matter. On August 11, 2020, the 11th Circuit Court of Appeals affirmed the Georgia district court’s denial of the board members’ motion to dismiss. On December 8, 2020, the 11th Circuit Court of Appeals voted to have a rehearing en banc. The FTC and DOJ filed an amicus and participated in oral argument that was held on February 23, 2021. On July 20, 2021, the 11th Circuit Court of Appeals ruled in the Company’s favor, finding that the Georgia Dental Board did not have an interlocutory right of appeal and therefore denied the Georgia Board’s appeal. On July 29, 2021, the 11th Circuit Court of Appeals also denied the Alabama Dental Board’s appeal. Both cases were remanded to the respective District Courts to proceed accordingly into the discovery phase.

On November 22, 2021, the Georgia Board filed a motion to dismiss in the Northern District of Georgia. On January 6, 2022, a hearing was held on the motion to dismiss. The parties await a final order and discovery is ongoing.

On August 17, 2021, the Alabama Dental Board and the Company entered into a tentative settlement agreement, subject to the FTC’s proposed Consent Order being entered into by the Board, precluding the Alabama Dental Board from engaging in conduct intended to preclude teledentistry in the State of Alabama or to preclude dentists and orthodontists from using the Company’s teledentistry platform to treat patients. On December 22, 2021, the Consent Order was finalized, and the District Court in Alabama thereafter entered its order approving the joint motion for dismissal of the lawsuit per the terms of the settlement reached between the parties.

On July 12, 2021, the Australian Competition & Consumer Commission filed an Originating Application against SmileDirectClub, LLC and the Company’s Australian affiliate SmileDirectClub Aus Pty Ltd. The Originating Application alleges certain misstatements by the Company in connection with the availability of consumers having the ability to have private health care coverage cover a portion of their costs when seeking treatment through the Company’s telehealth platform. The Company has denied any wrongdoing and has filed its Concise Response to the Statement of Claim. Should the matter not be resolved, trial has been scheduled to commence on April 17, 2023.

In March 2019, a final arbitration award was issued in an arbitration proceeding brought by the Company alleging that one of our former members, Align, violated certain restrictive covenants set forth in its operating agreement. The arbitrator ruled that Align breached both the non-competition and confidentiality provisions of the Company’s operating agreement and that, as a result, Align was required to close its Invisalign Stores, return all of the Company’s confidential information, and sell its membership units to the Company or certain of its pre-IPO unitholders for an amount equal to the balance of Align’s capital account as of November 2017. The arbitrator also extended the non-competition period to which Align is subject through August of 2022 and prohibited Align from using the Company’s confidential information in any manner going forward. The Company paid Align $54.0 million, pursuant to a promissory note payable over 24 months through March 2021, in full redemption of Align’s membership units pursuant to this ruling. The ruling has been confirmed in its entirety in the circuit court of Cook County, Chicago, Illinois, but Align continued to object to the purchase price and repurchase documentation despite the arbitration ruling and its confirmation, and filed a subsequent arbitration proceeding disputing the $54.0 million redemption amount and seeking an additional $43.4 million. Arbitration was held in December 2020. The arbitrator reached final decision in March 2021 and the Company paid Align the remaining amount of $43.4 million (which it had reserved) plus accrued interest.

In December 2020, a class action complaint was filed in the Illinois state court: Stacy Benbow et al. v. SmileDirectClub, Inc. et al., 2020 CH 07269 (Cook County Circuit Court filed 12/14/20). The complaint alleges violations of the Telephone Consumer Protection Act and seeks to represent a nationwide class of similarly situated persons. The complaint seeks injunctive relief, statutory damages, and attorneys’ fees and costs. A tentative settlement was approved by the court and the Company has recorded an estimated loss of $4.8 million related to such tentative settlement. Notice to the class was sent on March 20, 2021, and final approval was set for May 19, 2021. On May 19, 2021, the final approval was granted by the Cook County Circuit Court. The final cost of the settlement was approximately $4.0 million.

Tax Receivable Agreement

61

As described in Note 8, the Company is a party to the Tax Receivable Agreement pursuant to which SDC Inc. is contractually committed to pay the Continuing LLC Members 85% of the amount of any tax benefits that SDC Inc. actually realizes, or in some cases is deemed to realize, as a result of certain transactions. The Company is not obligated to make any payments under the Tax Receivable Agreement until the tax benefits associated with the transactions that gave rise to the payments are realized. TRA Payments are contingent upon, among other things, (i) generation of future taxable income over the term of the Tax Receivable Agreement and (ii) future changes in tax laws. If the Company does not generate sufficient taxable income in the aggregate over the term of the Tax Receivable Agreement to utilize the tax benefits, then it will not be required to make the related TRA Payments. During the years ended December 31, 2021 and 2020, the Company recognized no liabilities relating to its obligations under the Tax Receivable Agreement, after concluding that it was not probable that the Company would have sufficient future taxable income over the term of the Tax Receivable Agreement to utilize the related tax benefits. There were no transactions subject to the Tax Receivable Agreement for which the Company recognized the related liability, as the Company concluded that it would not have sufficient future taxable income to utilize all of the related tax benefits.

PART II

Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Market Information

Our Class A common stock trades on the NASDAQ Global Market under the symbol “SDC”. As of February 25, 2022, there were approximately 17 holders of record of our Class A common stock. Because the majority of our shares 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.

Dividends

Holders of our Class A common stock are entitled to receive dividends when, as and if declared by the board of directors. We have not historically paid cash dividends and we have no current plans to pay dividends. The timing, declaration and payment of future dividends to holders of our Class A common stock will depend upon many factors, including our financial condition, results of operations, capital requirements, contractual, legal, tax and regulatory restrictions, general business conditions, and other factors that our board of directors may deem relevant.

Item 7. 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 in conjunction with our consolidated financial statements and related notes thereto included elsewhere in this Annual Report on Form 10-K. In addition to historical consolidated financial information, the following discussion contains forward-looking statements that reflect our plans, estimates, and beliefs. Our actual results could differ materially from those discussed in any forward-looking statements. Factors that could cause or contribute to these differences include those factors discussed below, disclosed elsewhere in this Annual Report on Form 10-K, particularly under the heading “Risk Factors.” See “Cautionary Statement Regarding Forward-Looking Statements.”

We are an oral care company and the creator of the first MedTech platform for teeth straightening. Through our cutting-edge teledentistry technology and vertically integrated model, we are revolutionizing the oral care industry, from clear aligner therapy to our affordable, premium oral care product line. Our mission is to democratize access to a smile each and every person loves by making it affordable and convenient for everyone. We are headquartered in Nashville, Tennessee and operate in the U.S., Costa Rica, Puerto Rico, Canada, Australia, United Kingdom, France, and Ireland.

Key Business Metrics

We review the following key business metrics to evaluate our business performance:

Unique aligner order shipments

For the years ended December 31, 2021 and 2020, we shipped 332,388 and 374,982 unique aligner orders, respectively. Each unique aligner order shipment represents a single contracted member. We believe that our ability to increase the number of aligner orders shipped is an indicator of our market penetration, growth of our business, consumer interest, and our member conversion.

Average aligner gross sales price

We define average gross sales price (‘‘ASP”) as gross revenue, before implicit price concession and other variable considerations and exclusive of sales tax, from aligner orders shipped divided by the number of unique aligner orders shipped. We believe ASP is an indicator of the value we provide to our members and our ability to maintain our pricing. Our ASP for the years ended December 31, 2021 and 2020 was $1,883 and $1,797, respectively. Our ASP is less than our standard $1,950 price as a result of discounts offered to select members.

Key Factors Affecting Our Performance

We believe that our future performance will depend on many factors, including those described below and in the section titled “Risk Factors” included in Part I, Item 1A. of this Annual Report on Form 10-K.

COVID-19 pandemic

Although increasing rates of vaccinations across the globe and decreasing governmental restrictions have begun to lessen the impact of COVID-19, we continue to navigate the uncertain and unprecedented economic and operating conditions resulting from the COVID-19 pandemic and its protracted duration.

Additionally, we took the following actions beginning in the second quarter of 2020 in an effort to fortify the financial position of the business: reduced our marketing spend as a percentage of revenue; reduced our headquarters and retail workforce; secured the HPS Credit Facility and further strengthened our balance sheet with the convertible notes offering in February 2021, which resulted in the extinguishment of the HPS Credit Facility and more favorable interest rates; and initiated a real estate repositioning program.

64

Beginning in the second quarter of 2020, we performed a review of our real estate needs and initiated restructuring actions related to a real estate repositioning program that remains on-going. As a result of these actions, we incurred one-time charges of approximately $32.5 million in the year ended December 31, 2020. This one-time charge was primarily associated with the closure of our manufacturing facility in Kyle, Texas; the consolidation of several floors at our headquarters in Nashville, Tennessee; the closure and consolidation of many of our SmileShops, which is an ongoing evaluation; and the impairment of right of use assets and leasehold improvements at the closed SmileShops. During the year ended December 31, 2021, we incurred one-time charges of approximately $5.3 million, respectively, primarily associated with lease abandonment and store closure costs including the costs to exit certain foreign markets, Germany, Austria, and the Netherlands, due to the uncertain operating environment and immaturity of those markets as well as regulatory challenges. Further, in January 2022, we exited the Singapore, Hong Kong, New Zealand, Spain, and Mexico markets to focus on those markets that have the greatest potential for near-term profitability. We continue to evaluate our properties to determine if we will further rationalize our footprint to better align with marketplace demand, including the direct and indirect effects of the COVID-19 pandemic.

We bolstered our business continuity plans to address the evolving and on-going operational challenges associated with COVID-19. Specifically, we have a crisis management team that meets regularly with the heads of all functional areas to monitor the regulatory environment and health and safety guidelines and to manage the corresponding changes and impacts to our business. Our technology platforms continue to support a majority work from home environment. Our demand forecasting process is integrated with our suppliers to allow us to maintain target inventory levels. This collaborative relationship also allows us to monitor the impact of COVID-19 on our suppliers, review their related action plans and confirm they meet our standards as well as public health guidelines.

We believe that our teledentistry platform is well suited for the current operating environment. Our impression kit offers the ability to begin treatment or obtain any necessary touch-ups (mid-course corrections or refinements) remotely from home. During the COVID-19 pandemic, we experienced a customer shift towards impression kits, with approximately 60% of our clear aligner sales originating from impression kits during the second half of 2020 and first quarter of 2021. As governmental restrictions began to ease during the second quarter of 2021, we began to see a shift towards a more normalized mix of clear aligner sales originating from impressions kits versus scans in our SmileShops, Partner Network, and popup locations, with approximately 50% of our clear aligner sales originating from impression kits beginning in the third quarter of 2021. Although we cannot know or control the duration and severity of COVID-19 and its impact on our business, we will continue to focus on efficient acquisition of new members, including higher income customers, and controlled growth, each as more specifically discussed below.

Cybersecurity Incident

On May 3, 2021, the Company announced that it experienced a systems outage that was caused by a cybersecurity incident on April 14, 2021 (the “Incident”). We promptly implemented a series of containment and remediation measures to address the Incident, including temporarily isolating and shutting down affected systems and related manufacturing operations. We immediately mobilized our internal engineering security team and engaged leading forensic information technology firms to assist our investigation into the Incident. As a result of these efforts, we were able to successfully block the attack, no ransom was paid, and our systems and operations are back online and performing normally.

We had no data loss from, or other loss of assets as a result of, the Incident, including any exposure of customer or team member information. The Incident, however, caused delays and disruptions to parts of our business, including treatment planning, manufacturing operations, and product delivery. We maintain insurance coverage for certain expenses and potential liabilities that may be associated with the Incident, and we are pursuing coverage for all applicable expense and liabilities. The Incident had a material impact on business operations and financial results in the second quarter, including a delay in fulfilling customer orders. As a result, we experienced a decrease to revenue and increase to certain costs associated with our response to the Incident.

Efficient acquisition of new members

•Visits to our website: During the fourth quarter of 2021, we averaged approximately 4 million unique visitors to our website each month, and we expect to continue to invest in sales and marketing to spread awareness and increase the number of individuals visiting our website.

•Conversions from visits to aligner orders: From our website, individuals can either sign up for a SmileShop appointment, order a doctor prescribed impression kit or book an appointment at an affiliated dentist or orthodontist office, which we refer to as our “Partner Network,” to evaluate and ultimately purchase our clear aligner treatment. We expect to continue to invest heavily in our proprietary technology platform, operations, and other processes to improve member conversion from website visit through SmileShop and Partner Network appointment booking, appointment attendance, and aligners ordered; and a similar process for our impression kits.

•Referrals: During the fourth quarter of 2021, we remained strong on our member experience with referrals reaching 21% of all orders. We expect to continue to invest in our member journey to improve our member experience and increase our member referrals.

SmilePay

We offer SmilePay, a convenient monthly payment plan, to maximize accessibility and provide an affordable option for all of our members. The $250 down payment for SmilePay covers our cost of manufacturing the aligners, and the interest income generated by SmilePay more than offsets the negative impact of delinquencies and cancellations. A number of factors affect delinquency and cancellation rates, including member-specific circumstances, our efforts in member service and management, and the broader macroeconomic environment.

Continued investment in controlled growth

We intend to continue investing in our business to support future growth by focusing on strategies that best address our large market opportunity, both domestically and internationally, and focus on cost discipline across the business. Our key growth initiatives include enhancing our existing product platform; introducing new products to further differentiate our offerings; expanding our customer acquisition channels; expanding our reach through the professional channel; and expanding our market share with more traditional, higher income customers of clear aligner therapy. Additionally, we are focused on continued advancement in automating and streamlining our manufacturing and treatment planning operations to allow us to stay ahead of consumer demand; continued discipline around marketing and selling investments, including a focus on pushing more demand through our existing SmileShop network and Partner Network, comprised of affiliated dentist and orthodontist offices, and leveraging our referrals, aided awareness, and customer acquisition strategies. We also intend to continue to develop a suite of ancillary products for our members’ oral care needs, lengthening our relationship with our members and enhancing our recurring revenue base. As part of these key investment initiatives, we will also continue to explore collaborations with retailers and other third-party partnerships as a component of our strategy.

Pace of adoption for teledentistry

The rate of adoption of teledentistry will impact our ability to acquire new members and grow our revenue.

Strategic actions to increase profitability

On January 24, 2022, we announced a series of strategic actions to position us for improved business performance and future growth, including right-sizing our cost structure to better support core growth initiatives and allocating capital to countries with the greatest potential for near-term profitability.

Following an evaluation of our business and the continuing macroeconomic factors impacting consumers, we implemented initiatives including the expansion of our professional channel, the SmileDirectClub Partner Network;

66

innovations to our aligner products so as to allow us to capture greater market share of the teen and higher-household income demographics; focusing on our burgeoning oral care product business; and SmileShop growth in markets with strong consumer demand. Expansion into new international markets is paused while the global economy recovers from pandemic and macroeconomic pressures that have contributed to challenging operating environments.

In connection with these operational changes, we suspended operations in Mexico, Spain, Germany, Netherlands, Austria, Hong Kong, Singapore and New Zealand. We continue to operate in and scale its presence in the United States, Canada, United Kingdom, Ireland, France and Australia.

Components of Operating Results

Revenues

Our revenues are derived primarily from sales of aligners, impression kits, whitening gel, retainers, and other oral care products, as well as interest earned on SmilePay. Revenues are recorded based on the amount that is expected to be collected, which considers implicit price concessions, discounts, and cancellations and refunds from customer returns. Revenues include revenue recognized from orders shipped in the current period, as well as deferred revenue recognized from orders in prior periods. We offer our members the option of paying the entire cost of their clear aligner treatment upfront or enrolling in SmilePay, our convenient monthly payment plan requiring a down payment and a monthly payment for up to 24 months.

Financing revenue includes interest earned on SmilePay aligner orders shipped in prior periods. Our average APR is approximately 20%, which is included in the monthly payment.

Cost of revenues

Cost of revenues includes the total cost of products produced and sold. Such costs include direct materials, direct labor, overhead costs (occupancy costs, indirect labor, and depreciation), fees retained by doctors, freight and duty expenses associated with moving materials from vendors to our facilities and from our facilities to our members, and adjustments for shrinkage (physical inventory losses), lower of cost or net realizable value, slow moving product, and excess inventory quantities.

We manufacture all of our aligners and retainers in our manufacturing facilities. We continue to invest in automating our manufacturing and treatment planning operations, launching our second generation manufacturing at the end of the third quarter of 2020, which is contributing to increased efficiencies in our manufacturing process as evidenced by our increased margins. We have built extensive supply chain mechanisms that allow us to quickly and accurately create treatment plans and manufacture aligners.

Marketing and selling expenses

Our marketing expenses include costs associated with an omni-channel approach supported by mixed media marketing (“MMM”). These costs include online sources, such as social media and paid search, and offline sources, such as television, experiential events, local events, and business-to-business partnerships. We also have comprehensive strategies across search engine optimization, customer relationship management (“CRM”) marketing, and earned and owned marketing. We have invested significant resources into optimizing our member conversion process.

Our selling costs include both labor and non-labor expenses associated with our SmileShops, Partner Network, and popup locations and costs associated with our sales and scheduling teams in our customer contact center. Non-labor costs associated with our SmileShops and popup locations include rent, travel, supplies, and depreciation costs associated with digital photography equipment, furniture, and computers, among other costs.

67

General and administrative expenses

General and administrative expenses include payroll and benefit costs for corporate team members, equity-based compensation expenses, occupancy costs of corporate facilities, bank charges and costs associated with credit and debit card interchange fees, outside service fees, and other administrative costs, such as computer maintenance, supplies, travel, and lodging.

Interest and other expenses

Interest expense includes interest from our financing agreements and other long-term indebtedness. Other expense includes unrealized gains and losses on currency translation adjustments related to certain intercompany loan agreements between legal entities, disposal of long-lived assets, and other non-operating gains and losses.

Provision for income tax expense

We are subject to U.S. federal, state, and local income taxes with respect to our allocable share of any taxable income of SDC Financial, and we are taxed at the prevailing corporate tax rates. In addition to tax expenses, we also incur tax expenses related to our operations, as well as payments under the Tax Receivable Agreement. We receive a portion of any distributions made by SDC Financial. Any cash received from such distributions from our subsidiaries will first be used by us to satisfy any tax liability and then to make any payments required under the Tax Receivable Agreement. See Note 9.

Adjusted EBITDA

To supplement our consolidated financial statements presented in accordance with GAAP, we also present Adjusted EBITDA, a financial measure which is not based on any standardized methodology prescribed by GAAP.

We define Adjusted EBITDA as net loss, plus depreciation and amortization, interest expense, income tax expense, equity-based compensation, loss on extinguishment of debt, impairment of long-lived assets, abandonment and other related charges and certain other non-operating expenses, such as one-time store closure costs associated with our real estate repositioning strategy, severance, retention and other labor costs, certain one-time legal settlement costs, and unrealized foreign currency adjustments. Adjusted EBITDA does not have a definition under GAAP, and our definition of Adjusted EBITDA may not be the same as, or comparable to, similarly titled measures used by other companies. We use Adjusted EBITDA when evaluating our performance when we believe that certain items are not indicative of operating performance. Adjusted EBITDA provides useful supplemental information to management regarding our operating performance, and we believe it will provide the same to members/stockholders.

We believe that Adjusted EBITDA will provide useful information to members/stockholders about our performance, financial condition, and results of operations for the following reasons: (i) Adjusted EBITDA is among the measures used by our management team to evaluate our operating performance and make day-to-day operating decisions and (ii) Adjusted EBITDA is frequently used by securities analysts, investors, lenders, and other interested parties as a common performance measure to compare results or estimate valuations across companies in our industry. Adjusted EBITDA should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. A reconciliation of Adjusted EBITDA to net loss, the most directly comparable GAAP financial measure, is set forth below.

Comparison of the years ended December 31, 2021 and 2020

Revenues

69

Revenues decreased $19.2 million, or 2.9%, to $637.6 million in the year ended December 31, 2021 from $656.8 million in the year ended December 31, 2020. The decrease in revenues was primarily driven by decreased aligner shipments compared to the prior year period as a result of the continuing effects of the COVID-19 pandemic resulting in negative macroeconomic factors impacting our core demographic, including lower discretionary spending and a challenging economic environment impacted by increased inflation, partially offset by growth in our international markets, primarily the U.K.

For the years ended December 31, 2021 and 2020, revenues for the U.S. and Canada were approximately $525.4 million and $568.8 million, or 82.4% and 86.6%, respectively, and revenues for the rest of world were approximately $112.2 million and $88.0 million, or 17.6% and 13.4%, respectively.

Cost of revenues

Cost of revenues decreased $29.3 million, or 14.1%, to $177.6 million in the year ended December 31, 2021 from $206.9 million in the year ended December 31, 2020. Cost of revenues decreased as a percentage of revenues from 31.5% in the year ended December 31, 2020 to 27.9% in the year ended December 31, 2021, primarily due to continued automation of our manufacturing processes. The decrease in overall cost of revenues in the current year as compared to the prior year is primarily due to producing a lower number of aligners in the current year.

Gross margin increased to 72.1% in the year ended December 31, 2021 from 68.5% in the year ended December 31, 2020, primarily as a result of the factor described above.

Marketing and selling expenses

Marketing and selling expenses as a percentage of revenues increased to 60.9% in the year ended December 31, 2021 from 49.2% in the year ended December 31, 2020, and increased to $388.5 million in the year ended December 31, 2021 from $322.9 million in the year ended December 31, 2020. The increase was primarily due to the reopening of several of our SmileShops and increasing our international footprint, the implementation of our pop-up event strategy, and the redeployment of our marketing strategy as compared to the prior year period which was impacted by cost containment measures implemented in response to the COVID-19 pandemic.

General and administrative expenses

General and administrative expenses increased $13.6 million, or 4.4%, to $325.6 million in the year ended December 31, 2021 from $312.0 million in the year ended December 31, 2020. The increase was primarily due to increases in personnel costs as a result of increased headcount and the absence of certain cost containment measures affecting the prior year period, partially offset by lower incentive compensation cost. General and administrative expenses as a percent of revenue increased from 47.5% in the year ended December 31, 2020 to 51.1% in the year ended December 31, 2021, primarily due to the factors mentioned above.

Lease abandonment, impairment of long-lived assets and other related charges

Lease abandonment, impairment of long-lived assets and other related charges were $5.3 million for the year ended December 31, 2021, compared to $32.5 million for the year ended December 31, 2020. These charges are primarily associated with the closure and consolidation of a portion of our SmileShops, and the impairment of right of use assets and leasehold improvements at our closed SmileShops. Additionally, the current year period includes costs associated with the consolidation of our facilities in Costa Rica and the prior year period included charges related to the closure of our manufacturing facility in Kyle, Texas, and the consolidation of several floors at our headquarters in Nashville, Tennessee. We continue to evaluate our SmileShops and other properties to determine if we will further rationalize our footprint to better align with marketplace demand, including direct and indirect effects of the COVID-19 pandemic.

Interest expense

70

Interest expense decreased $21.9 million to $23.2 million in the year ended December 31, 2021 from $45.0 million in the year ended December 31, 2020, primarily as a result of a change in our capital structure that significantly reduced our effective interest rate on our outstanding debt facilities.

Loss on extinguishment of debt

Loss on extinguishment of debt in the year ended December 31, 2021 was $47.6 million. The expense was in conjunction with the payoff of the HPS Credit Facility on March 29, 2021. The cost was primarily made up of fees paid in connection with the termination of the HPS Credit Facility and unamortized fees and warrant costs associated with the initiation of the transaction in the prior year. Loss on extinguishment of debt in the year ended December 31, 2020 was $13.8 million, respectively, primarily made up of fees and unamortized costs associated with our previous JPM facility.

Other expense (income)

Other expense (income) increased $5.2 million to expense of $4.3 million in the year ended December 31, 2021 from income of $0.9 million in the year ended December 31, 2020. The increase in expense was primarily due to the impact of unrealized foreign currency translation adjustments.

Provision for income tax expense

Our provision for income tax expense was $1.3 million and $3.1 million for the years ended December 31, 2021 and 2020, respectively.

Adjusted EBITDA

For the year ended December 31, 2021, Adjusted EBITDA was negative $133.2 million compared to a negative $77.1 million for the year ended December 31, 2020. For the year ended December 31, 2021, Adjusted EBITDA for the U.S. and Canada combined was a negative $65.1 million, and Adjusted EBITDA for the rest of world for the year ended December 31, 2021 was negative $68.1 million.

Comparison of the years ended December 31, 2020 and 2019

Revenues

Revenues decreased $93.6 million, or 12.5%, to $656.8 million in the year ended December 31, 2020 from $750.4 million in the year ended December 31, 2019. The decrease in revenues was primarily driven by the impacts of COVID-19 on our operations, particularly in the second and third quarters of 2020. Unique aligner shipments decreased approximately 17% for the year ended December 31, 2020 compared to the same period in 2019. This decrease in unique aligner shipments as a result of the COVID-19 pandemic was partially offset by an increase in non-aligner revenue of approximately $41.1 million.

Cost of revenues

Cost of revenues increased $28.5 million, or 16.0%, to $206.9 million in the year ended December 31, 2020 from $178.4 million in the year ended December 31, 2019. Cost of revenues increased as a percentage of revenues from 23.8% in the year ended December 31, 2019 to 31.5% in the year ended December 31, 2020, as a result of COVID-19 related changes to the composition of our revenue mix. Specifically, we experienced an increase in retail sales of oral care products as a percentage of revenue, which represents a lower associated gross margin. Additionally, a higher percentage of our aligner sales were driven by impression kits compared to the prior period, which resulted in higher material and shipping costs.

Gross margin decreased to 68.5% in the year ended December 31, 2020 from 76.2% in the year ended December 31, 2019, primarily as a result of the factors described above.

71

Marketing and selling expenses

Marketing and selling expenses as a percentage of revenues decreased to 49.2% in the year ended December 31, 2020 from 64.2% in the year ended December 31, 2019, and decreased to $322.9 million in the year ended December 31, 2020 from $481.5 million in the year ended December 31, 2019, primarily due to cost containment measures taken as a result of the effects of COVID-19 on our revenues, including more efficient marketing spend and realignment of our SmileShops to align with demand and operate at a higher utilization percentage driving margin improvement.

General and administrative expenses

General and administrative expenses decreased $268.9 million, or 46.3%, to $312.0 million in the year ended December 31, 2020 from $580.8 million in the year ended December 31, 2019. The prior year period included equity-based compensation expense of $350.1 million and other employee related bonuses of $9.9 million primarily as a result of the IPO, compared to equity-based compensation of $44.9 million in the current period. The current year period also included $6.6 million in one-time costs related to legal settlements and severance costs. Adjusting for equity-based compensation, IPO related costs and one-time items for the current and prior period, general and administrative expenses increased $39.7 million or 18.0% from $220.8 million in the prior year to $260.5 million primarily due to the expansion of our team members and services to support our business growth prior to the COVID-19 outbreak as well as higher depreciation and amortization associated with investments in the business. General and administrative expenses as a percent of revenue, adjusted for the items listed above, increased from 29.4% in the year ended December 31, 2019 to 39.7% in the year ended December 31, 2020, primarily as a result of the factors mentioned above.

Lease abandonment, impairment of long-lived assets and other related charges

Lease abandonment, impairment of long-lived assets and other related charges were $32.5 million for the year ended December 31, 2020, compared to $0.0 million for the year ended December 31, 2019. These charges are primarily associated with the closure of our manufacturing facility in Kyle, Texas; the consolidation of several floors at our Company headquarters in Nashville, Tennessee; the closure and consolidation of a portion of our SmileShops, which is an on-going evaluation; and the impairment of right of use assets and leasehold improvements at our closed SmileShops. We continue to evaluate our SmileShops and other properties to determine if we will further rationalize our footprint to better align with marketplace demand, including direct and indirect effects of the COVID-19 pandemic.

Interest expense

Interest expense increased $29.3 million, or 186.1%, to $45.0 million in the year ended December 31, 2020 from $15.7 million in the year ended December 31, 2019, primarily as a result of both higher principal balances and interest rates related to the HPS Credit Facility.

Other income

Other income increased $0.7 million to $0.9 million in the year ended December 31, 2020 from $0.1 million in the year ended December 31, 2019, primarily as a result of unrealized foreign currency translation adjustments.

Provision for income tax expense

Our provision for income tax expense was $3.1 million and $2.3 million for the years ended December 31, 2020 and 2019, respectively.

72

Liquidity and Capital Resources

As of December 31, 2021, SDC Inc. had cash on hand of $224.9 million, an accumulated deficit of $295.3 million and had working capital of $289.5 million. Our operations have been financed primarily through net proceeds from the sale of our equity securities and borrowings under our debt instruments.

Our short-term liquidity needs primarily include working capital, innovation, and research and development. We believe that our current liquidity, including net proceeds received in connection with the IPO and other financing transactions, will be sufficient to meet our projected operating, investing, and debt service requirements for at least the next 12 months. Our future capital requirements may vary materially from those currently planned and will depend on many factors, including our levels of revenue, the expansion of sales and marketing activities, market acceptance of our clear aligners, the results of research and development and other business initiatives, the timing of new product introductions, and overall economic conditions. To the extent that current and anticipated future sources of liquidity are insufficient to fund our future business activities and requirements, we may be required to seek additional equity or debt financing. The sale of additional equity would result in additional dilution to our stockholders. The incurrence of additional debt financing would result in debt service obligations, and any future instruments governing such debt could provide for operating and financing covenants that would restrict our operations. In February 2021, we issued approximately $650.0 million aggregate principal amount of convertible senior Notes in a private placement offering. We also issued an additional $97.5 million aggregate principal amount of the Notes to the initial purchasers under an option granted to the initial purchasers. The proceeds of this offering were used by us to enter into privately negotiated capped call transactions with certain of the initial purchasers, which are expected to reduce dilution to the Class A common stock upon any conversion of the Notes, and we used a portion of the remainder of the net proceeds to repay amounts owed under the HPS Credit Facility. In connection with the issuance of the Notes, SmileDirectClub, Inc. entered into an intercompany convertible promissory note (“Intercompany Convertible Note”) with SDC Financial, LLC, whereby SmileDirectClub, Inc. provided the net proceeds from the issuance of the Notes to SDC Financial, LLC. The terms of the Intercompany Convertible Note mirrors the terms of the Notes issued by SmileDirectClub, Inc. The intent of the Intercompany Convertible Note is to maintain the parity of shares of Class A common stock with LLC Units as required by the SDC Financial LLC Agreement.

We are a holding company with no operations of our own and, as such, we depend on our subsidiaries for cash to fund all of our operations and expenses. We depend on the payment of distributions by our subsidiaries, and such distributions may be restricted as a result of regulatory restrictions, state and international laws regarding distributions, or contractual agreements, including agreements governing indebtedness. For a discussion of those restrictions, see “Risk Factors—Risks Related to Our Organization and Structure—We are a holding company. Our sole material asset is our equity interest in SDC Financial, and as such, we depend on our subsidiaries for cash to fund all of our expenses, including taxes and payments under the Tax Receivable Agreement.” We currently anticipate that such restrictions will not impact our ability to meet our cash obligations.

Comparison of the year ended December 31, 2021 and 2020

As of December 31, 2021, we had $224.9 million in cash, a decrease of $91.9 million compared to $316.7 million as of December 31, 2020.

Cash used in operating activities increased to $141.5 million during the year ended December 31, 2021 compared to $83.6 million in the year ended December 31, 2020, or an increase of $58.0 million, primarily due to the increase in net loss during the period and changes in working capital.

Cash used in investing activities increased to $106.6 million during the year ended December 31, 2021, compared to $97.1 million in the year ended December 31, 2020. Cash used in investing activities primarily consisted of purchases of manufacturing automation equipment and investments in technology equipment and software as well as international expansion for both periods.

Cash provided by financing activities decreased to $155.7 million during the year ended December 31, 2021, compared to $179.0 million in the year ended December 31, 2020. Cash provided by financing activities during the year ended December 31, 2021 primarily consists of the issuance of approximately $747.5 million principal amount of the 2026 Convertible Senior Notes in a private placement offering, including options. We incurred transaction costs associated with the issuance of the Notes of approximately $21.2 million and entered into privately negotiated capped call transactions with certain of the initial purchasers in the amount of approximately $69.5 million, which are expected to reduce dilution to the Class A common stockholders upon any conversion of the Notes. Approximately $434.2 million of the proceeds from the Notes were used to repay the HPS Credit Facility in full, including certain prepayment and make-whole provisions. In addition, we paid Align Technology, Inc. the remaining $43.4 million of equity value previously accrued plus interest pursuant to an arbitration award. In the prior year period, cash provided by financing activities primarily consisted of approximately $388.0 million from the HPS Credit Facility, offset by the repayment of prior debt facilities.

Comparison of the years ended December 31, 2020 and 2019

As of December 31, 2020, we had $316.7 million in cash, a decrease of $1.7 million compared to $318.5 million as of December 31, 2019.

Cash used in operating activities decreased to $83.6 million during the year ended December 31, 2020 compared to $333.2 million in the year ended December 31, 2019, or a decrease of $249.6 million, primarily resulting from a decrease in accounts receivable associated with our SmilePay offering and decreased net loss during the period. One-time cash compensation expense of approximately $83.6 million for the payment of cash bonus amounts pursuant to management incentive bonus agreements (“IBAs”) was incurred in October 2019.

Cash used in investing activities decreased to $97.1 million during the year ended December 31, 2020, compared to $106.4 million in the year ended December 31, 2019, primarily resulting from a decrease in the number of SmileShop locations, partially offset by purchases of manufacturing automation equipment and investments in technology and software equipment as well as international expansion to support our planned growth.

Cash provided by financing activities decreased to $179.0 million during the year ended December 31, 2020, compared to $444.1 million in the year ended December 31, 2019. This decrease in cash provided by financing activities is primarily due to net proceeds received from the JPM Facility and IPO in the prior year period as compared to net proceeds received from the HPS Credit Facility in the current year period.

Tax Receivable Agreement

Our purchase of LLC Units from SDC Financial, coupled with SDC Financial’s purchase and cancellation of LLC Units from the Pre-IPO investors in connection with the IPO and any future exchanges of LLC Units for our Class A common stock or cash are expected to result in increases in our allocable tax basis in the assets of SDC Financial that otherwise would not

These increases in tax basis are expected to provide us with certain tax benefits that can reduce the amount of cash tax that we otherwise would be required to pay in the future. We and SDC Financial are parties to the Tax Receivable Agreement with the Continuing LLC Members, pursuant to which we are obligated to pay the Continuing LLC Members 85% of the cash savings, if any, in U.S. federal, state, and local income tax or franchise tax that we actually realize as a result of (a) the increases in tax basis attributable to exchanges by Continuing LLC Members and (b) tax benefits related to imputed interest deemed to be paid by us as a result of the Tax Receivable Agreement. The amounts to be recorded for both the deferred tax assets and the liability for our obligations under the Tax Receivable Agreement will be estimated at the

time of an exchange of LLC Units. All of the effects of changes in any of our estimates after the date of the exchange will be included in net loss. Similarly, the effect of subsequent changes in the enacted tax rates will be included in net loss. Because we are the managing member of SDC Financial, which is the managing member of SDC LLC, which is the managing member of SDC Holding, we have the ability to determine when distributions (other than tax distributions) will be made by SDC Holding to SDC LLC and by SDC LLC to SDC Financial and the amount of any such distributions, subject to limitations imposed by applicable law and contractual restrictions (including pursuant to our debt instruments). Any such distributions will then be distributed to all holders of LLC Units, including us, pro rata based on holdings of LLC Units. The cash received from such distributions will first be used by us to satisfy any tax liability and then to make any payments required under the Tax Receivable Agreement. We expect that such distributions will be sufficient to fund both our tax liability and the required payments under the Tax Receivable Agreement.

Indebtedness

Convertible Senior Notes

On February 9, 2021 we issued $650.0 million principal amount of Notes and also granted the initial purchasers of the Notes an option to purchase up to an additional $97.5 million aggregate principal amount of the Notes. The sale of the Notes concluded on February 16, 2021, with the initial purchasers exercising their options in full to buy the additional Notes. The Notes were issued and governed by an indenture, dated February 9, 2021, (the “Indenture”), between us and Wilmington Trust, National Association, as trustee. Overall, we incurred $747.5 million principal amount of indebtedness as a result of this offering.

A portion of the proceeds of the offering of the Notes were used to fund the cost of privately negotiated capped call transactions with certain initial purchasers, and we used a portion of the remainder of the net proceeds to repay amounts owed under the HPS Credit Facility.

The Notes will mature on February 1, 2026, unless earlier repurchased, redeemed or converted. The Notes will not bear regular interest, and the principal amount of the Notes will not accrete.

If certain corporate events that constitute a “Fundamental Change” (as defined in the Indenture) occur or “Events of Default” (as defined in the Indenture) occur, then, noteholders may require the Company to repurchase their Notes at a cash repurchase price equal to the principal amount of the Notes to be repurchased, plus accrued and unpaid special interest, if any.

HPS Credit Facility

On May 12, 2020, we and a wholly-owned special purpose subsidiary, SDC U.S. SmilePay SPV (“SPV”), entered into a Loan Agreement among SPV, as borrower, SmileDirectClub, LLC, as the seller and servicer, certain lenders, and HPS Investment Partners, LLC, as administrative agent and collateral agent, providing a five-year secured term loan facility to SPV in an initial aggregate maximum principal amount of $400 million, with the ability to request incremental term loans of up to an additional aggregate principal amount of $100 million with the consent of the lenders participating in such increase.

The proceeds of the HPS Credit Facility were used to repay all outstanding amounts under the previous JPM Credit Facility and for working capital and other corporate purposes.

75

Outstanding loans under the HPS Credit Facility bore interest at a variable rate equal to three-month LIBOR (subject to a 1.75% per annum floor), plus 7.50% per annum payable in cash, plus 3.25% per annum payable in kind or, at the Company’s election, wholly or partially in cash.

Subject to certain exceptions, the HPS Credit Facility was secured by first-priority security interests in SPV’s assets, which consist of certain receivables, cash, intellectual property and related assets. SPV’s obligations under the Loan Agreement were guaranteed on a limited basis by SmileDirectClub, LLC and SDC Financial.

The HPS Credit Facility could have been refinanced during the first year, provided that SPV would be required to pay the amount of interest that would have accrued during the remainder of the first year, plus 4% of the principal amount prepaid; and after the first year, for a fee of 4% of the principal amount prepaid, with the prepayment fee decreasing each year to 3% in the third year, 2% in the fourth year and 1% in the fifth year.

On March 29, 2021, the HPS Credit Facility was repaid in full.

See Note 10 to the consolidated financial statements for further discussion of the Notes.

Tax Receivable Agreement

The payments that we may be required to make under the Tax Receivable Agreement to the Continuing LLC Members may be significant and are dependent upon future taxable income. See “Certain Relationships and Related Party Transactions-Tax Receivable Agreement.”

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which we have prepared in accordance with GAAP. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that impact the reported amounts. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition and equity-based compensation, among others. Each of these estimates varies in regard to the level of judgment involved and its potential impact on our financial results. Estimates are considered critical either 1) when a different estimate could have reasonably been used, or 2) where changes in the estimate are reasonably likely to occur from period to period, and such use or change would materially impact our financial condition, results of operations, or cash flows. Actual results could differ from those estimates. While our significant accounting policies are more fully described in Note 2 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K, we believe that the following accounting policies and estimates are most critical to a full understanding and evaluation of our reported financial results.

Revenue recognition

As discussed in Note 2 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K, we have implemented ASC 606, “Revenue from Contracts with Customers,” as of January 1, 2017 using the full retrospective method.

Our revenue is generated through sales of aligners, retainers, and other oral care products. Our aligner sales commitment contains multiple promises which may include (i) initial aligners, and (ii) touch-up aligners. Our members are eligible for modified or refinement aligners, which we refer to as “touch-up aligners,” at any point during their treatment plan or immediately following their original treatment plan (which is typically between five and ten months), in each case, upon the direction of, and pursuant to a prescription from, the treating dentist or orthodontist. Under ASC 606, we evaluate whether the initial aligners and touch-up aligners represent separate or combined performance obligations. We have determined that these promises, within the aligner sales commitment, represent separate performance obligations.

76

The terms of the aligner and retainer sales include member rights to cancel the orders and return unopened aligner, impression kit, or retainer boxes for a refund of any consideration paid related to the returned products. The rights of return create variability in the amount of transaction consideration, and in turn, revenue we can recognize for fulfilling related performance obligations. We recognize revenue based on the amount of consideration to which we expect to be entitled, which excludes consideration received for products expected to be cancelled or refunded due to customer returns. Accordingly, we are required to make estimates of expected returns and related revenue adjustments. We estimate expected customer returns based upon our assessment of historical and expected cancellations. The estimated expected refunds are recorded as a refund liability.

We offer our members the option of paying for the entire cost of their aligners upfront or enrolling in SmilePay, a convenient monthly payment plan that requires a $250 down payment, with the remaining consideration due over a period up to 24 months. Approximately 60% of our members elect to purchase our aligners using SmilePay. The amount of contract consideration we estimate to be collectible from our SmilePay members results in an implicit price concession. We estimate the amount of implicit price concession based upon our assessment of historical write-offs and expected net collections, business and economic conditions, including the uncertainty of the lasting effects of the COVID-19 pandemic, and other collection indicators. We believe our analysis provides reasonable estimates of our revenues and valuations of our accounts receivable.

Revenue is recognized for touch-up aligners when the promised goods are transferred to the member. Touch-up aligners represent a promise to transfer goods to members, and not all members order touch-up aligners. We make our best estimate of touch-up aligner member usage rates, which we use to determine the amount of revenue to allocate to those performance obligations at inception of our aligner sales commitment. Our process for estimating usage rates requires significant judgment and evaluation of inputs, including historical data and forecasted usages. Any material changes to usage rates could impact the timing of revenue recognition, which may have a material effect on our financial position and result of operations.

Amounts received prior to satisfying the above revenue recognition criteria are recorded as a contract liability in deferred revenue in our historical consolidated balance sheets. The deferred revenue balance is subject to fluctuation depending on the timing and fulfillment of aligner orders.

Equity-based compensation

We account for equity-based compensation for team members in accordance with ASC 718, “Compensation-Stock Compensation.” In accordance with ASC 718, compensation cost is measured at estimated fair value on grant date and is included as compensation expense over the vesting period during which a team member provides service in exchange for the award.

We used the Black-Scholes Option Pricing Method to allocate the total equity fair value to outstanding Options. The Black-Scholes Option Pricing Method includes various assumptions, including the expected life of Options, the expected volatility, and the expected risk-free interest rate. These assumptions reflect our best estimates, but they involve inherent uncertainties based on market conditions generally outside our control. As a result, if other assumptions had been used, equity-based compensation cost could have been materially impacted. Furthermore, if we use different assumptions for future grants, equity-based compensation cost could be materially impacted in future periods.

The fair value of RSUs is determined by our stock price on the date of grant and related compensation expense is generally recognized over the requisite service period.

Income tax expense

We are the managing member of SDC Financial and, as a result, consolidate the financial results of SDC Financial. SDC Financial and its subsidiaries are limited liability companies and have elected to be taxed as partnerships for income tax purposes except for a subsidiary, SDC Holding, that is treated like a corporation. As such, SDC Financial does not pay any federal income taxes, as any income or loss will be included in the tax returns of the individual members. SDC Financial does

77

pay state income tax in certain jurisdictions, and the Company’s income tax provision in the consolidated financial statements reflects the income taxes for those states. Additionally, certain wholly-owned entities are required to be looked at on a stand-alone basis resulting in federal income taxes, and such federal income taxes are included in the consolidated financial statements.

We use the asset and liability method to account for income taxes and apply the principles of ASC 740, “Income Taxes,” in determining when our tax positions should be recognized. Under this method, deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. If a net operating loss carryforward exists, we make a determination as to whether that net operating loss carryforward will be utilized in the future. A valuation allowance will be established for certain net operating loss carryforwards and other deferred tax assets where the recoverability is deemed to be uncertain. The carrying value of the net deferred tax assets is based upon estimates and assumptions related to our ability to generate sufficient future taxable income in certain tax jurisdictions. If these estimates and related assumptions change in the future, we will be required to adjust our deferred tax valuation allowances.

In connection with the Reorganization Transactions and the IPO, we entered into the Tax Receivable Agreement with certain of the Continuing LLC Members that provides for the payment by us of 85% of the amount of any tax benefits that the Company actually realizes, or in some cases is deemed to realize, as a result of (i) increases in the Company’s share of the tax basis in the net assets of SDC Financial resulting from any redemptions or exchanges of LLC Units, (ii) tax basis increases attributable to payments made under the Tax Receivable Agreement, and (iii) deductions attributable to imputed interest pursuant to the Tax Receivable Agreement (the “TRA Payments”). We expect to benefit from the remaining 15% of any of cash savings, if any, that we realize.

The amounts payable under the Tax Receivable Agreement will vary depending upon a number of factors, including the amount, character, and timing of the taxable income of the Company in the future. If the valuation allowance recorded against the deferred tax assets applicable to the tax attributes referenced above is released in a future period, the Tax Receivable Agreement liability may be considered probable at that time and recorded within earnings.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Interest rate risk

Our cash and cash equivalents consist primarily of an interest-bearing accounts at large U.S. banks with limited interest rate risk. We intend to maintain our portfolio of cash equivalents in a variety of investment-grade securities, which may include commercial paper, money market funds, and government and non-government debt securities. Because of the short-term maturities of our cash and cash equivalents and marketable securities, we do not believe that an increase in market rates would have any significant negative impact on the realized value of our investments. At December 31, 2021, we held no investments in marketable securities.

On February 9, 2021 we issued $650.0 million principal amount of Notes and also granted the initial purchasers of the Notes an option to purchase up to an additional $97.5 million aggregate principal amount of the Notes. The sale of the Notes concluded on February 16, 2021, with the initial purchasers exercising their options, in full, to buy the additional Notes. Overall, we incurred $747.5 million principal amount of indebtedness as a result of this offering. The Notes were issued at a 0.0% coupon rate.

A portion of the proceeds of the offering of the Notes were used to fund the cost of privately negotiated capped call transactions with certain initial purchasers, and we used a portion of the remainder of the net proceeds to repay amounts owed under the HPS Credit Facility.

Foreign currency exchange risk

A substantial majority of our revenue, cost, expense and capital purchasing activities for the year ended December 31, 2021 were transacted in United States dollars. As we are expanding our sales and operations internationally, we are more exposed to changes in foreign exchange rates. Currently, our international revenue is predominantly from Canada and the U.K. and denominated in Canadian dollars and Great British Pounds, respectively, with a limited portion from Australia, Ireland, and France, and denominated in their local currencies. In the future, as we continue to expand into additional international jurisdictions, we expect that our international sales will be primarily denominated in foreign currencies and that any unfavorable movement in the exchange rate between U.S. dollars and the currencies in which we conduct foreign sales could have an adverse impact on our revenue. To minimize this risk, our expenses, other than manufacturing, are incurred in local currency to effectively create a natural hedge against currency risk.

A portion of our operating expenses are incurred outside the United States and are denominated in foreign currencies, which are also subject to fluctuations due to changes in foreign currency exchange rates. In particular, in our Costa Rican operations, we pay payroll and other expenses in Costa Rican colones. In addition, our suppliers incur many costs, including labor costs, in other currencies. To the extent that exchange rates move unfavorably for our suppliers, they may seek to pass these additional costs on to us, which could have a material impact on our gross margins. Our operating results and cash flows are, therefore, subject to fluctuations due to changes in foreign currency exchange rates. However, we believe that the exposure to foreign currency fluctuation from operating expenses is relatively small at this time as the related costs do not constitute a significant portion of our total expenses.

Our exposures to foreign currency risks may change as we continue to grow our international operations and could have a material adverse impact on our financial results. We may in the future hedge our foreign currency exposure and may use currency forward contracts, currency options, and/or other common derivative financial instruments to reduce foreign currency risk. It is difficult to predict the effect any future hedging activities would have on our operating results.

Inflation risk

Inflationary factors, such as increases in our cost of revenues, advertising costs and other selling and operating expenses, may adversely affect our operating results. A high rate of inflation may have an adverse effect on our ability to maintain and

79

increase our gross margin or to maintain current levels of selling, general, administrative and other operating expenses as a percentage of revenues if the selling price of our products do not increase with these increased costs.

Credit risk

We are exposed to credit risk through our SmilePay financing option. For the year ended December 31, 2021, approximately 60% of our members chose to finance their treatment through SmilePay. For the years ended December 31, 2021 and 2020, SmilePay amounted to approximately $243.8 million and $293.3 million in net receivables and associated delinquency rates of 9%. We may experience an increase in payment defaults and uncollectible accounts, and may be required to revise our collection estimates, which would adversely affect our revenue and net loss.

Item 9A. Controls and Procedures

Disclosure Controls and Procedure

Our management under the supervision and with the participation of the Company’s Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”) is responsible for establishing and maintaining “disclosure controls and procedures” (as defined in rules promulgated under the Securities Exchange Act of 1934, as amended) for the Company. Based on their evaluation the CEO and CFO have concluded that the Company’s disclosure controls and procedures were effective as of December 31, 2021.

Management's Report on Internal Control Over Financial Reporting

We are responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is 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. 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 our assets;

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

•provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our consolidated 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 and that the degree of compliance with the policies or procedures may deteriorate.

80

We assessed the effectiveness of our internal control over financial reporting as of December 31, 2021. In making this assessment, we used the criteria set forth in the Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on our assessment, we believe that as of December 31, 2021, our internal control over financial reporting is effective based on those criteria.

The effectiveness of our internal control over financial reporting as of December 31, 2021, has been audited by Ernst & Young LLP, the independent registered public accounting firm who also audited the Company’s consolidated financial statements included in this Annual Report on Form 10-K. Ernst & Young LLP’s report on the Company’s internal control over financial reporting is included in this Annual Report on Form 10-K.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(d) and 15d-15(d) under the Exchange Act) during the period covered by this Annual Report on Form 10-K that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 9B. Other Information

On February 24, 2022, Senator William H. Frist, M.D. notified the Company of his intention to resign as a member of the Board, effective as of February 24, 2022, as he is taking on a new executive role in an entity that will require a significant amount of his time.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of SmileDirectClub, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of SmileDirectClub, Inc. (the Company) as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive loss, changes in equity (deficit) and cash flows for each of the three years in the period ended December 31, 2021, and the related notes and financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated March 1, 2022, expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter 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
Description of the Matter	For the year ended December 31, 2021, the Company’s net revenues were $637.6 million, net of implicit price concessions, cancellations and refunds of $129.3 million. As discussed in Note 2 to the consolidated financial statements, revenue is recorded for all customers based on the amount that is expected to be collected, which considers implicit price concessions, discounts, cancellations and refunds from customer returns. The Company bills its customers either upfront for the full cost of aligners or monthly through its SmilePay financing program, which involves a down payment and a fixed amount per month for up to 24 months. The Company’s accounts receivable related to the SmilePay financing program are reported at the amount expected to be collected on the consolidated balance sheets, which considers implicit price concessions. Financing revenue from its accounts receivable is recognized based on the contractual market interest rate with the customer, net of implicit price concessions. The Company recorded estimated implicit price concessions related to SmilePay members to reflect the revenues and accounts receivable at the estimated amounts expected to be collected based upon management’s assessment of historical write-offs and expected net collections, business and economic conditions, and other collection indicators. The Company also offers return rights that create variability in the amount of transaction consideration that can be recorded related to cancellations and refunds from customer returns. The Company recorded revenue adjustments to reflect the revenues at the estimated amounts to be collected based upon management’s assessment of historical and expected cancellations and refunds Auditing the Company’s estimates of implicit price concessions and cancellations is complex due to the significant uncertainty inherent to the estimate, the application of management judgment, and the subjective assumptions as noted above utilized in estimating the expected amounts to be collected.
How We Addressed the Matter in Our Audit	To test the estimated implicit price concessions and cancellations, our audit procedures included, among others, evaluating the estimation methodologies used, the significant assumptions described above, and the underlying data used by the Company. We performed testing over the completeness and accuracy of data inputs used by the Company in the estimation process, including historical collection experience and historical and expected cancellations. We compared the significant assumptions used by management to current business and economic trends and considered changes to the Company’s business and other relevant factors. We performed sensitivity analyses of the impact of changes to the assumptions on the resulting estimate of the implicit price concessions and cancellations. We also assessed the historical accuracy of management’s estimates based on subsequent collection experience as a source of potential corroborative or contrary evidence regarding the assumptions used by management in the estimation process.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition of 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 (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) 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 (3) provide 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.

Notes to Consolidated Financial Statements (Continued)

For the year ended December 31, 2021
(in thousands, except share/unit data and per share/unit amounts)

Note 1—Organization and Basis of Presentation

Organization

SmileDirectClub, Inc. was formed on April 11, 2019 with no operating assets or operations as a Delaware corporation for the purpose of facilitating an initial public offering and other related transactions in order to carry on the business of SDC Financial LLC and its subsidiaries. Unless otherwise indicated or the context otherwise requires, references to “we,” “us,” “our,” the “Company,” “SmileDirectClub,” and similar references refer to SmileDirectClub, Inc. and its consolidated subsidiaries, including SDC Financial LLC and its subsidiaries. “SDC Financial” refers to SDC Financial LLC and “SDC Inc.” refers to SmileDirectClub, Inc. The Company is engaged by its network of doctors to provide a suite of non-clinical administrative support services, including access to and use of its SmileCheck platform, as a dental support organization. For purposes of these Notes to Consolidated Financial Statements, the Company’s affiliated network of dentists and orthodontists is included in the definition of “we,” “us,” “our,” and the “Company” as it relates to any clinical aspect of the member’s treatment. All of the Company’s manufacturing operations are directly or indirectly conducted by Access Dental Lab, LLC (“Access Dental”), one of its operating subsidiaries.

SmileDirectClub is an oral care company and creator of the first MedTech platform for teeth straightening. Through the Company’s cutting-edge teledentistry technology and vertically integrated model, it is revolutionizing the oral care industry, from clear aligner therapy to its affordable, premium oral care product line. SmileDirectClub’s mission is to democratize access to a smile each and every person loves by making it affordable and convenient for everyone. SmileDirectClub is headquartered in Nashville, Tennessee and operates in the U.S., Costa Rica, Puerto Rico, Canada, Australia, United Kingdom, France, and Ireland.

SDC Inc. is a holding company. Its sole material asset is its equity interest in SDC Financial which, through its direct and indirect subsidiaries, conducts all of the Company’s operations. SDC Financial is a Delaware limited liability company and wholly owns SmileDirectClub, LLC (“SDC LLC”) (a Tennessee limited liability company) and Access Dental (a Tennessee limited liability company). Because SDC Inc. is the managing member of SDC Financial, SDC Inc. indirectly operates and controls all of the business and affairs of SDC Financial and its subsidiaries.

Initial Public Offering

On September 16, 2019, SDC Inc. completed an initial public offering (“IPO”) of 58,537,000 shares of its Class A common stock at a public offering price of $23.00 per share. SDC Inc. received $1,286 million in proceeds, net of underwriting discounts and commissions. SDC Inc. used substantially all of the net proceeds after expenses to purchase newly-issued membership interest units from SDC Financial.

Reorganization Transactions

In connection with the IPO, the Company completed the following transactions (the “Reorganization Transactions”):

•the formation of SDC Inc. as a Delaware corporation to function as the ultimate parent of SmileDirectClub and a publicly traded entity;

•SDC Inc.’s acquisition of the pre-IPO membership interest units in SDC Financial (“Pre-IPO Units”) held by certain pre-IPO investors that are taxable as corporations for U.S. federal income tax purposes (“Blockers”), pursuant to a series of mergers (the “Blocker Mergers”) of the Blockers with wholly owned subsidiaries of SDC Inc., and the issuance by SDC Inc. to the equityholders of the Blockers shares of Class A common stock as consideration in the Blocker Mergers;

•the amendment and restatement of the SDC Financial’s limited liability company operating agreement (the “SDC Financial LLC Agreement”) to, among other things, modify the capital structure of SDC Financial by replacing the

SmileDirectClub, Inc.

Notes to Consolidated Financial Statements (Continued)

For the year ended December 31, 2021
(in thousands, except share/unit data and per share/unit amounts)

different classes of Pre-IPO Units (including restricted Pre-IPO Units held by certain employees) with a single new class of membership interests of SDC Financial (“LLC Units”);

•the issuance to each of the pre-IPO investors previously holding Pre-IPO Units (including restricted Pre-IPO Units) of a number of shares of SDC Inc. Class B common stock equal to the number of LLC Units held by it;

•the issuance to certain employees of cash and shares of Class A common stock pursuant to their Incentive Bonus Agreements (“IBAs”); and

•the equitable adjustment, pursuant to their terms, of outstanding warrants to purchase Pre-IPO Units held by two service providers into warrants to acquire LLC Units (together with an equal number of shares of SDC Inc.’s Class B common stock).

Following the completion of the Reorganization Transactions and the IPO, SDC Inc. owned 26.9% of SDC Financial. Holders (other than SDC Inc.) of LLC Units following the consummation of the Reorganization Transactions and the IPO (“Continuing LLC Members”) owned the remaining 73.1% of SDC Financial.

SDC Inc. is the sole managing member of SDC Financial and, although SDC Inc. has a minority economic interest in SDC Financial, it has the sole voting power in, and controls the management of, SDC Financial. Accordingly, SDC Inc. consolidates the financial results of SDC Financial and reports a noncontrolling interest in its consolidated financial statements. As the Reorganization Transactions are considered transactions between entities under common control, the financial statements for periods prior to the IPO and Reorganization Transactions have been adjusted to combine the previously separate entities for presentation purposes.

In connection with the Reorganization Transactions and the IPO, the Company entered into a Tax Receivable Agreement (the “Tax Receivable Agreement”) with the Continuing LLC Members, pursuant to which SDC Inc. agreed to pay the Continuing LLC Members 85% of the amount of cash tax savings, if any, in U.S. federal, state, and local income tax or franchise tax that SDC Inc. actually realizes as a result of (a) the increases in tax basis attributable to exchanges of LLC Units by Continuing LLC Members and (b) tax benefits related to imputed interest deemed to be paid by SDC Inc. as a result of the Tax Receivable Agreement.

Basis of Presentation and Consolidation

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

The consolidated financial statements include the accounts of SDC Inc., which consolidates SDC Financial and its wholly-owned subsidiaries, as well as accounts of contractually affiliated professional corporations (“PCs”) managed by the Company.

The consolidated financial statements include the accounts of variable interest entities in which the Company is the primary beneficiary under the provisions of Accounting Standards Codification (‘‘ASC”) Topic 810, ‘‘Consolidation.” At December 31, 2021, the variable interest entities include 53 dentist owned PCs, and at December 31, 2020 the variable interest entities included 54 dentist owned PCs. The Company is a dental service organization and does not engage in the practice of dentistry. All clinical services are provided by dentists and orthodontists who are engaged as independent contractors or otherwise engaged by the dentist-owned PCs. The Company contracts with the PCs and dentists and orthodontists through a suite of agreements, including but not limited to, management services agreements, supply agreements, and licensing agreements, pursuant to which the Company provides the administrative, non-clinical management services to the PCs and independent contractors. The Company has the contractual right to manage the activities that most significantly impact the variable interest entities’ economic performance through these agreements without engaging in the corporate practice of dentistry. Additionally, the Company would absorb substantially all of the expected losses of these

entities should they occur. The accompanying consolidated statements of operations reflect the revenue earned and the expenses incurred by the PCs.

COVID-19 Pandemic

Although increasing rates of vaccinations across the globe and decreasing governmental restrictions have begun to lessen the impact of COVID-19, the Company continues to navigate the uncertain and unprecedented economic and operating conditions resulting from COVID-19 and its protracted duration. In response to COVID-19 and the related containment measures, the Company made the following operational changes beginning in the second quarter of 2020 to ensure the health and safety of its employees and its members: transitioned its team members, where possible, to a remote working environment; closed a portion of its SmileShops based on the Company’s real estate repositioning program as well as local public health guidelines and evolving customer behaviors and expectations; reconfigured its SmileShops and popup locations to reduce customer overlap in the waiting area and require touchless temperature screening upon arrival; heightened the personal protective equipment protocol (“PPE”) requirements for Smile Guides; reconfigured its production lines to observe social distancing; and implemented enhanced cleaning and sanitizing routines, thermal temperature screening, mandatory PPE protocols and other health and safety measures at its manufacturing facilities. The Company also enacted a resilience policy that provides its team members paid leave for COVID-19 testing and up to two weeks of paid leave for any required self-quarantine due to the team member testing positive for COVID-19.

Additionally, the Company took the following actions beginning in the second quarter of 2020 in an effort to fortify the financial position of the business: reduced its marketing spend as a percentage of revenue; reduced its headquarters and retail workforce; secured long-term financing; and initiated a real estate repositioning program.

Beginning in the second quarter of 2020, the Company performed a review of its real estate needs and initiated restructuring actions related to a real estate repositioning program that remains ongoing. As a result of these actions, the Company incurred one-time charges of approximately $32,491 during the year ended December 31, 2020. This one-time charge was primarily associated with the closure of our manufacturing facility in Kyle, Texas; the consolidation of several floors at our headquarters in Nashville, Tennessee; the closure and consolidation of many of our SmileShops, which is an on-going evaluation; and the impairment of right of use assets and leasehold improvements at the closed SmileShops. During the year ended December 31, 2021, the Company incurred one-time charges of approximately $5,279, primarily associated with store closure costs and further consolidation of corporate office space. Given the uncertain operating environment and the shift to work-from-home, the Company made the strategic decision to align its rent costs with the current needs of the business, while also ensuring that the Company has sufficient capacity to support future growth. The Company continues to evaluate its properties to determine if it will further rationalize its footprint to better align with marketplace demand, including the direct and indirect effects of the COVID-19 pandemic.

Note 2—Summary of Significant Accounting Policies

Management Use of Estimates

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that impact the reported amounts. On an ongoing basis, the Company evaluates its estimates, including those related to the fair values of financial instruments, useful lives of property, plant and equipment, revenue recognition, equity-based compensation, long-lived assets, and contingent liabilities, among others. In connection with its credit facility with HPS Investment Partners, the Company issued warrants to certain affiliates of HPS Investment Partners. The warrants were recorded at fair value at the time of issuance within equity on the consolidated balance sheet using the Black-Scholes option pricing model (see Note 10). Each of these estimates varies in regard to the level of judgment involved and its potential impact on the Company’s financial results. Estimates are considered critical either when a different estimate could have reasonably been used, or where changes in the estimate are reasonably likely to occur from period to period, and such use or change would materially impact the Company’s financial condition, results of operations, or cash flows. Actual results could differ from those estimates.

Revenue Recognition

The Company’s revenues are derived primarily from sales of aligners, impression kits, whitening gel, and retainers, and interest earned through its SmilePay financing program. Revenue is recorded for all customers based on the amount that is expected to be collected, which considers implicit price concessions, discounts, and cancellations and refunds from customer returns.

The Company 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 (“SSP”) and allocation of consideration from a 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, usage rates (the number of times a customer is expected to order additional aligners), costs, and expected margin, which may vary over time depending upon the unique facts and circumstances related to each performance obligation, in making these estimates. Further, the Company’s process for estimating usage rates requires significant judgment and evaluation of inputs, including historical data and forecasted usages. Changes in the allocation of the SSP between performance obligations will not affect the amount of total revenues recognized for a particular contract. The Company uses the expected cost plus a margin approach to determine the SSP for performance obligations, and discounts are allocated to each performance obligation based on the relative SSP. However, any material changes in the allocation of the SSP could impact the timing of revenue recognition, which may have a material effect on the Company’s financial position and result of operations as 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.

The Company estimates the amount expected to be collected based upon management’s assessment of historical write-offs, expected net collections including implicit price concessions, and cancellations and refunds from customer returns, business and economic conditions, and other collection indicators. Management relies on the results of detailed reviews of historical write-offs, cancellations, returns, and collections as a primary source of information in estimating the amount of contract consideration expected to be collected. Uncollectible receivables are written-off in the period management believes it has exhausted its ability to collect payment from the customer. The Company believes its analysis provides reasonable estimates of its revenues and valuations of its accounts receivable.

A description of the revenue recognition for each product sold by the Company is detailed below.

Aligners and Impression Kits: The Company enters into contracts with customers for aligner sales that involve multiple future performance obligations. The Company determined that aligner sales comprise the following distinct performance

SmileDirectClub, Inc.

Notes to Consolidated Financial Statements (Continued)

For the year ended December 31, 2021
(in thousands, except share/unit data and per share/unit amounts)

obligations: initial aligners, touch-up aligners, and retainers for international sales only which can occur at any time throughout the treatment plan (which is typically between five months to ten months) upon the direction of and prescription from the treating dentist or orthodontist.

The Company allocates revenues for each performance obligation based on its SSP and recognizes the revenues as control of the performance obligation is transferred upon shipment of the aligners. The Company recognizes aligner revenue on amounts expected to be collected during the course of the treatment plan.

The Company bills its customers either upfront for the full cost of aligners or monthly through its SmilePay financing program, which involves a down payment and a fixed amount per month for up to 24 months. The Company’s accounts receivable related to the SmilePay financing program are reported at the amount expected to be collected on the consolidated balance sheets, which considers implicit price concessions. Financing revenue from its accounts receivable is recognized based on the contractual market interest rate with the customer, net of implicit price concessions. There are no fees or origination costs included in accounts receivable.

The Company sells doctor-prescribed impression kits to its customers as an alternative to an in-person visit at one of its SmileShops, popup locations, or Partner Network locations, comprised of affiliated dentist and orthodontist offices, where the customer receives a free oral digital imaging of their teeth. The Company combines the sales of its impression kits with aligner sales and recognizes the revenues as control of the performance obligation is transferred upon shipment of the aligners. The Company estimates the amount of impression kit sales that do not result in an aligner therapy treatment plan and recognizes such revenue when aligner conversion becomes remote.

Retainers and Other Products: The Company sells retainers and other products (such as whitening gel and tooth brushes) to customers, which can be purchased on the Company’s website or certain retail outlets. The sales of these products are independent and separate from the customer’s decision to purchase aligner therapy for domestic sales. The Company determined that the transfer of control for these performance obligations occurs as the title of such products passes to the customer or retail partner.

The following table summarizes revenue recognized for each product sold by the Company:

	Years Ended December 31,
	2021		2020		2019
Aligner revenue, net	$	517,552	$	543,136	$	683,429
Financing revenue, net	42,919		49,407		43,899
Retainers and other products revenue	77,140		64,237		23,100
Total revenue	$	637,611	$	656,780	$	750,428
Implicit price concessions, cancellations, and refunds included in total revenue	$	129,307	$	138,841	$	125,535

Deferred Revenue: Deferred revenue represents the Company’s contract liability for performance obligations associated with sales of aligners. During the years ended December 31, 2021, 2020, and 2019, the Company recognized $637,611, $656,780, and $750,428 of revenue, respectively, of which $22,550, $19,750 and $16,630 was previously included in deferred revenue on the consolidated balance sheets as of December 31, 2020, 2019 and 2018, respectively.

Allowance for credit losses and other revenue adjustments: The Company records a provision to maintain an allowance for credit losses and other revenue adjustments that result from the failure or inability of its members or other partners to make required payments deemed collectible when the product was delivered, or customer returns resulting in cancellations or refunds. When determining the allowances for member receivables, the Company considers the probability of recoverability of accounts receivable based on past experience, taking into account current collection trends and general economic factors, including bankruptcy rates. The Company also considers future economic trends in its estimation of expected credit losses over the lifetime of the asset. Credit risks are assessed based on historical write-offs, cancellations, and adjustments, net of

(in thousands, except share/unit data and per share/unit amounts)

recoveries, as well as an analysis of the aged accounts receivable balances. Accounts receivable may be fully reserved for when specific collection issues are known to exist, such as a history of missed scheduled payments and customer service or production issues.

Activity in the allowance for credit losses and other revenue adjustments for the year ended December 31, 2021 was as follows:

Balance at December 31, 2020	$	53,740
Current period provision for expected credit losses and other revenue adjustments	129,307
Write-offs and other adjustments charged against the allowance, net of recoveries	(116,031)
Refunds paid	(17,707)
Balance at December 31, 2021	$	49,309

As of December 31, 2021 and 2020, approximately $43,097 and $49,264 related to implicit price concessions and cancellation and adjustment reserves and is included in net receivables, respectively, and $6,212 and $4,476 related to refund reserves and is included in current liabilities in the accompanying consolidated balance sheets, respectively.

Shipping and Handling Costs

Shipping and handling charges are recorded in cost of revenues in the consolidated statements of operations upon shipment. The Company incurred approximately $22,892, $23,036 and $19,000 in outsourced shipping expenses for the years ended December 31, 2021, 2020 and 2019, respectively.

Cost of Revenues

Cost of revenues includes the total cost of products produced and sold. Such costs include direct materials, direct labor, overhead costs (occupancy costs, indirect labor, and depreciation), fees retained by doctors, freight and duty expenses associated with moving materials from vendors to the Company’s facilities and from its facilities to the customers, and adjustments for shrinkage (physical inventory losses), lower of cost or net realizable value, slow moving product and excess inventory quantities.

Marketing and Selling Expenses

Marketing and selling expenses include direct online and offline marketing and advertising costs, costs associated with intraoral imaging services, selling labor, and occupancy costs of SmileShop locations. All marketing and selling expenses, including advertising, are expensed as incurred. For the years ended December 31, 2021, 2020 and 2019, the Company incurred marketing, selling, and advertising costs of $388,450, $322,919 and $481,468, respectively.

General and Administrative Expenses

General and administrative expenses include payroll and benefit costs for corporate team members, equity-based compensation expenses, occupancy costs of corporate facilities, bank charges and costs associated with credit and debit card interchange fees, outside service fees, and other administrative costs, such as computer maintenance, supplies, travel, and lodging.

Depreciation and Amortization

Depreciation includes expenses related to the Company’s property, plant and equipment, including capital leases. Amortization includes expenses related to definite-lived intangible assets and capitalized software. Depreciation and amortization is calculated using the straight-line method over the useful lives of the related assets, ranging from three to ten years. Leasehold improvements are amortized using the straight-line method over the shorter of the related lease terms or

(in thousands, except share/unit data and per share/unit amounts)

their useful lives. Depreciation and amortization is included in cost of revenues, selling expenses, and general and administrative expenses depending on the purpose of the related asset.

Depreciation and amortization by financial statement line item were as follows:

	Years Ended December 31,
	2021		2020		2019
Cost of revenues	$	27,467	$	24,718	$	11,186
Marketing and selling expenses	5,001		7,079		5,322
General and administrative expenses	37,645		24,593		10,828
Total	$	70,113	$	56,390	$	27,336

Fair Value of Financial Instruments

The Company measures the fair value of financial instruments 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. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

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.

Level 3 — Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability.

The Company’s financial instruments consist of cash, current and non-current receivables, accounts payable, debt instruments, and derivative financial instruments. Due to their short-term nature, the carrying values of cash, current receivables, and trade payables approximate current fair value at each balance sheet date. The Company had $747,500 and $407,902 in borrowings under its debt facilities (as discussed in Note 10) as of December 31, 2021 and 2020, respectively. The fair value of the Company’s debt facilities is based upon market quotes and trades by investors in partial interests of these instruments (Level 2). As of December 31, 2021 the fair value of the debt facility was approximately $305,167 compared to its carrying value of $729,973.

Derivative Financial Instruments

The Company accounts for derivative financial instruments in accordance with applicable accounting standards for such instruments and hedging activities, which require that all derivatives are recorded on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability. The Company had no outstanding derivatives at December 31, 2021

or 2020; however, the Company may enter into derivative contracts that are intended to economically hedge a certain portion of its risk, even though hedge accounting does not apply or the Company elects not to apply the hedge accounting standards.

Certain Risks and Uncertainties

The Company’s operating results depend to a significant extent on the ability to market and develop its products. The life cycles of the Company’s products are difficult to estimate due, in part, to the effect of future product enhancements and competition. The inability to successfully develop and market the Company’s products as a result of competition or other factors would have a material adverse effect on its business, financial condition, and results of operations.

The Company provides credit to customers in the normal course of business. The Company maintains reserves for potential credit losses and such losses have been within management’s expectations. No individual customer accounted for 1% or more of the Company’s accounts receivable at December 31, 2021 or 2020, or net revenue for the years ended December 31, 2021, 2020 and 2019.

Some of the Company’s products are considered medical devices and are subject to extensive regulation in the U.S. and internationally. The regulations to which the Company is subject are complex. Regulatory changes could result in restrictions on the Company’s ability to carry on or expand its operations, higher than anticipated costs or lower than anticipated sales. The failure to comply with applicable regulatory requirements may have a material adverse impact on the Company.

The Company’s reliance on international operations exposes it to related risks and uncertainties, including difficulties in staffing and managing international operations, such as hiring and retaining qualified personnel; 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, operating results may be harmed.

The Company purchases certain inventory from sole suppliers, and the inability of any supplier or manufacturer to fulfill the supply requirements could materially and adversely impact its future operating results.

Cash

Cash consists of all highly liquid investments with original maturities of less than three months. Cash is held in various financial institutions in the U.S. and internationally.

Inventories

Inventories are stated at the lower of cost or net realizable value using the first-in, first-out method of inventory accounting. Inventory consists of raw materials for producing impression kits and aligners and finished goods. Inventory is net of shrinkage and obsolescence.

Property, Plant and Equipment, Net

Property, plant and equipment are stated at cost less accumulated depreciation and amortization. Routine maintenance and repairs are charged to expense as incurred. At the time property, plant and equipment are retired from service, the cost and accumulated depreciation or amortization are removed from the respective accounts and the related gains or losses are reflected in the consolidated statements of operations.

Leases

On January 1, 2020, the Company adopted the new leases standard using the modified retrospective transition method, which requires that it recognizes leases differently pre- and post-adoption. The Company categorizes leases at their inception

F - 21

SmileDirectClub, Inc.

Notes to Consolidated Financial Statements (Continued)

(in thousands, except share/unit data and per share/unit amounts)

as either operating or finance leases. Lease agreements cover certain retail locations, office space, warehouse, manufacturing and distribution space and equipment. Operating leases are included in operating lease right-of-use assets, other current liabilities, and long-term right-of-use operating lease obligations in the consolidated balance sheets. Finance leases are included in property, plant and equipment, net, current portion of long-term debt, and long-term debt.

Leased assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The Company uses a secured incremental borrowing rate as the discount rate for determining the present value of lease payments when the rate implicit in the contract is not readily determinable. Leases that have a term of twelve months or less upon commencement date are considered short-term in nature. Accordingly, short-term leases are not included on the consolidated balance sheets and are expensed on a straight-line basis over the lease term, which commences on the date we have the right to control the property.

Internally Developed Software Costs

The Company generally provides services to its customers using software developed for internal use. The costs that are incurred to develop such software are expensed as incurred during the preliminary project stage. Once certain criteria have been met, direct costs incurred in developing or obtaining computer software are capitalized. Training and maintenance costs are expensed as incurred. Capitalized software costs are included in property, plant and equipment in the consolidated balance sheets and are amortized over useful life of the software which is generally a three-year to five-year period. During the years ended December 31, 2021, 2020, and 2019, the Company capitalized $58,558, $21,509 and $11,861, respectively, of internally developed software costs. Amortization expense for internally developed software was $17,973, $7,978 and $3,384 for the years ended December 31, 2021, 2020, and 2019, respectively.

Impairment

The Company evaluates long-lived 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 generate. Factors the Company considers 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. The Company’s estimates of future cash flows attributable to long-lived assets require significant judgment based on its 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 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.

Debt Issuance Costs

The Company records debt issuance costs related to its term debt as direct deductions from the carrying amount of the debt. The costs are amortized to interest expense over the life of the debt using the effective interest method.

Income Taxes

SDC Inc. is the managing member of SDC Financial and, as a result, consolidates the financial results of SDC Financial in the consolidated financial statements. SDC Financial and its subsidiaries are limited liability companies and have elected to be taxed as partnerships for income tax purposes except for a subsidiary, SDC Holding, LLC (‘‘SDC Holding”) and its domestic and foreign subsidiaries, which are taxed as corporations. As such, SDC Financial does not pay any federal income taxes, as any income or loss is included in the tax returns of the individual members. SDC Financial does pay state income

F - 22

SmileDirectClub, Inc.

Notes to Consolidated Financial Statements (Continued)

For the year ended December 31, 2021
(in thousands, except share/unit data and per share/unit amounts)

tax in certain jurisdictions, and the Company’s income tax provision in the consolidated financial statements reflects the income taxes for those states. Additionally, certain wholly-owned entities taxed as corporations are subject to federal, state, and foreign income taxes, in the jurisdictions in which they operate, and accruals for such taxes are included in the consolidated financial statements. The Company further evaluates deferred tax assets in each jurisdiction and recognizes associated benefits when positive evidence of realization exceeds negative evidence, and otherwise records valuation allowances as necessary.

The Company computes the provision for income taxes using the liability method and recognizes deferred tax assets and liabilities for temporary differences between financial statement and income tax bases of assets and liabilities, as well as for operating loss and tax credit carryforwards. The Company measures deferred tax assets and liabilities using tax rates applicable to taxable income in effect for the years in which those tax assets are expected to be realized or settled and provides a valuation allowance against deferred tax assets when it cannot conclude that it is more likely than not that some or all deferred tax assets will be realized. In addition, the Company recognizes tax benefits from uncertain tax positions only if it expects that its tax positions are more likely than not that they will be sustained, based on the technical merits of the positions, on examination by the jurisdictional tax authority. The Company recognizes any accrued interest and penalties to unrecognized tax benefits as interest expense and income tax expense, respectively.

Tax Receivable Agreement

In connection with the Reorganization Transactions and the IPO, the Company entered into a Tax Receivable Agreement with the Continuing LLC Members, pursuant to which SDC Inc. agreed to pay the Continuing LLC Members 85% of the amount of cash tax savings, if any, in U.S. federal, state, and local income tax or franchise tax that SDC Inc. actually realizes as a result of (a) the increases in tax basis attributable to exchanges by Continuing LLC Members and (b) tax benefits related to imputed interest deemed to be paid by SDC Inc. as a result of the Tax Receivable Agreement. The Company recognizes this contingent liability in its consolidated financial statements when amounts become probable as to incurrence and estimable in amount.

Recently Adopted Accounting Pronouncements

In January 2021 the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standard Update (“ASU”) 2016-13, “Financial Instruments—Credit Losses” (Topic 326). The FASB issued this update 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 adoption of this standard did not have a material impact on the Company’s consolidated financial statements and related disclosures.

In January 2021, the Company adopted FASB ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." This standard simplified the accounting for income taxes by eliminating certain exceptions to the guidance in Topic 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an period and the recognition of deferred tax liabilities for outside basis differences. The guidance also simplified aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill and allocating consolidated income taxes to separate financial statements of entities not subject to income tax. The Company adopted the provisions of this guidance effective January 1, 2021 using the modified retrospective method of adoption which required no cumulative-effect adjustment to retained earnings as of the beginning of the period.

In January 2021, the Company adopted FASB ASU 2020-06, “Accounting for Convertible Instruments and Contracts in an Entity's Own Equity,” which eliminates most of the guidance in Subtopic 470-20 that requires separate accounting for embedded conversion features in convertible debt arrangements. Further, ASU 220-06 removes some of the conditions in

Subtopic 815-40-25, “Contracts on an Entity's own Equity,” that are required for equity classification, including the requirement for equity contracts to permit settlement in unregistered shares. The Company adopted the provisions of this guidance effective January 1, 2021, using the modified retrospective method of adoption which required no cumulative-effect adjustment to retained earnings as of the beginning of the period. The Company applied the provisions of this guidance to the recently issued 2026 Convertible Senior Notes and related capped call transactions.

In March 2019, the Company purchased an intangible asset related to manufacturing. The Company evaluates the remaining useful life and carrying value of this indefinite-lived intangible asset at least annually or when events and circumstances warrant such a review, to determine whether significant events or changes in circumstances indicate that a change in the useful life or impairment in value may have occurred. There were no impairment charges related to the Company’s indefinite-lived intangible asset during the years ended December 31, 2021, or 2020.

Note 5—Lease Abandonment, Impairment of Long-lived Assets and Store Closure and Other Related Charges

The Company evaluates its real estate needs on a recurring basis and beginning in the second quarter of 2020, initiated restructuring actions related to a real estate repositioning program. As a result of these changes, the Company incurred one-time charges of $5,279 for the year ended December 31, 2021. These charges were primarily associated with store closure costs and consolidation of a portion of SmileShops, which is an on-going evaluation. Given the uncertain operating environment and the shift to work-from-home, the Company made the strategic decision to align its rent costs with the current needs of the business, while also ensuring that the Company has sufficient capacity to support future growth. The Company continues to evaluate its SmileShops and other properties to determine if it will further rationalize its footprint to

Note 7—Leases

The Company leases property and equipment under finance and operating leases. For leases with terms greater than 12 months, the Company records the related right-of-use assets and right-of-use obligations at the present value of lease payments over the term. Certain of the Company’s leases include rental escalation clauses and renewal options that are factored into the determination of lease payments when appropriate. Certain of the Company’s leased store locations have variable payments based upon scan volume as well as other variable property related costs. The Company does not separate lease and non-lease components of contracts.

(in thousands, except share/unit data and per share/unit amounts)

Generally, the Company uses its estimated incremental borrowing rate to discount the lease payments based on information available at lease commencement, as most of its leases do not provide a readily determinable implicit interest rate. The Company estimates its collateralized incremental borrowing rate based upon a synthetic credit rating and yield curve analysis at commencement or modification date in determining the present value of lease payments.

SDC Inc. is the managing member of SDC Financial and, as a result, consolidates the financial results of SDC Financial. SDC Financial and its subsidiaries are limited liability companies and have elected to be taxed as partnerships for income tax purposes, except for a subsidiary, SDC Holding and certain of its domestic and foreign subsidiaries, are taxed as corporations. The Company files income tax returns in the U.S. federal, various states and foreign jurisdictions. Any taxable income or loss

generated by SDC Financial is passed through to and included in the taxable income or loss of its members, including SDC Inc., generally on a pro rata basis or otherwise under the terms of the SDC Financial LLC Agreement. The Company is subject to U.S. federal income taxes, in addition to state and local income taxes with respect to its allocable share of any taxable income or loss of SDC Financial, as well as any stand-alone income or loss generated by SDC Inc.

The Company’s U.S. federal and state income tax returns for the tax years 2017 and beyond remain subject to examination by the Internal Revenue Service. The Company also has operations in Costa Rica, Puerto Rico, Canada, Mexico, Australia, the U.K., Germany, Austria, the Netherlands, Spain, Ireland, France, Hong Kong, Singapore, Taiwan, and New Zealand with tax filings in each foreign jurisdiction. With respect to state and local jurisdictions, the Company and its subsidiaries are typically subject to examination for several years after the income tax returns have been filed. Although the outcome of tax audits is always uncertain, the Company believes that adequate amounts of tax, interest and penalties have been provided for in the accompanying consolidated financial statements for any adjustments that may be incurred due to state or local audits and uncertain tax positions. The Company is also subject to withholding taxes in foreign jurisdictions. The Company’s income tax expense may vary from the expense that would be expected based on statutory rates due principally to its organizational structure and recognition of valuation allowances against deferred tax assets.

Deferred Tax Assets and Liabilities

Deferred income taxes reflect the net tax effects of tax carryovers and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the balances for income tax purposes. Significant components of deferred tax assets and liabilities are as follows:

	Years Ended December 31,
	2021		2020
Deferred tax assets:
Deferred revenue	$	369	$	351
Accruals and reserves	4,411		3,511

Gross deferred tax liabilities	(1,571)		(818)
Net deferred tax liabilities	$	(792)	$	(161)

At December 31, 2021 the Company had unused federal net operating loss carryforwards (tax effected) for federal income tax purposes of approximately $71,464, which can be carried forward indefinitely and may be used to offset future taxable income. In addition, the Company had unused net operating loss carryforwards (tax effected) for state income tax purposes of approximately $33,434, which expire from 2029 through 2035. The Company also had unused net operating loss carryforwards (tax effected) for foreign income tax purposes of approximately $6,515. Additionally, the Company has certain other deferred tax assets related to potential future tax benefits. All deferred tax assets are evaluated using positive and negative evidence as to their future realization. The Company considers recent historic losses to be significant negative evidence, and as such, records a valuation allowance against substantially all of its deferred tax assets.

(in thousands, except share/unit data and per share/unit amounts)

As of December 31, 2021, the Company maintained a valuation allowance of approximately $288,506 against its deferred tax assets. If there is a change in the Company’s assessment of the amount of deferred income tax assets that is realizable, adjustments to the valuation allowance will be made in future periods.

Unrecognized Tax Benefits

A reconciliation of the Company’s gross unrecognized tax benefits is as follows:

	Years Ended December 31,
	2021		2020
Balance at beginning of year	$	2,555	$	1,006
Increases for tax positions taken in prior years	—		462

Increases for tax positions taken in current year	438		1,087
Decreases for settlements with taxing authorities	—		—
Decreases for lapsing of the statute of limitations	(65)		—
Balance at end of year	$	2,928	$	2,555

The total amount of accrued interest and penalties were not significant as of December 31, 2021. The total amount of unrecognized tax benefit recorded during 2021 and 2020 was $2,928 and $2,555, respectively. All our unrecognized tax benefits, if recognized, would have a favorable impact on the effective tax rate.

Tax Receivable Agreement

The Company expects to obtain an increase in its share of the tax basis in the net assets of SDC Financial when LLC Units are redeemed from or exchanged by Continuing LLC Members. The Company intends to treat any redemptions and exchanges of LLC Units as direct purchases of LLC Units for U.S. federal income tax purposes. These increases in tax basis may reduce the amounts that it would otherwise pay in the future to various tax authorities. They may also decrease gains (or increase losses) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets.

In connection with the Reorganization Transactions and the IPO, the Company entered into the Tax Receivable Agreement with the Continuing LLC Members. The Tax Receivable Agreement provides for the payment by SDC Inc. of 85% of the amount of any tax benefits that SDC Inc. actually realizes, or in some cases is deemed to realize, as a result of (i) increases in SDC Inc.’s share of the tax basis in the net assets of SDC Financial resulting from any redemptions or exchanges of LLC Units, (ii) tax basis increases attributable to payments made under the Tax Receivable Agreement, and (iii) deductions attributable to imputed interest pursuant to the Tax Receivable Agreement (collectively, the “TRA Payments”). The Company expects to benefit from the remaining 15% of any of cash savings, if any, that it realizes.

During the year ended December 31, 2019, the Company acquired an aggregate of $635,690 in LLC Units in connection with the redemption of certain Continuing LLC Members, which resulted in an increase in the tax basis of the assets of SDC Financial subject to the provisions of the Tax Receivable Agreement. The Company has not recognized any additional liability under the Tax Receivable Agreement after concluding it was not probable that such TRA Payments would be paid based on its estimates of future taxable income. No payments were made to the Continuing LLC Members pursuant to the Tax Receivable Agreement during the years ended December 31, 2021 or 2020.

The amounts payable under the Tax Receivable Agreement will vary depending upon a number of factors, including the amount, character, and timing of the taxable income of SDC Inc. in the future. If the valuation allowance recorded against the deferred tax assets applicable to the tax attributes referenced above is released in a future period, the Tax Receivable Agreement liability may be considered probable at that time and recorded within earnings.

2026 Convertible Senior Notes

On February 9, 2021, the Company issued $650,000 principal amount of the Company’s 0.00% Convertible Senior Notes due 2026 (the “Notes”). The Company also granted the initial purchasers of the Notes an option to purchase up to an additional $97,500 aggregate principal amount of the Notes (“Option Notes”). On February 9, 2021, the initial purchasers of the Notes exercised their option to purchase $70,000 aggregate principal amount of the Option Notes (the “First Greenshoe Exercise”). The sale of the Option Notes from the First Greenshoe Exercise closed on February 12, 2021. On February 11, 2021, the initial purchasers of the Notes exercised the remaining portion of their option to purchase $27,500 aggregate principal amount of the Option Notes (the “Second Greenshoe Exercise” and, the Option Notes issued in connection with the Second Greenshoe Exercise, the “Second Greenshoe Option Notes”). The sale of the Second Greenshoe Option Notes closed on February 16, 2021.

The Notes were issued and governed by an indenture, dated February 9, 2021, (the “Indenture”), between the Company and Wilmington Trust, National Association, as trustee. The Notes will mature on February 1, 2026, unless earlier repurchased, redeemed or converted. The Notes will not bear regular interest, and the principal amount of the Notes will not accrete.

The initial conversion rate for the Notes is 55.3710 shares of the Company's Class A Common Stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $18.06 per share of Class A Common Stock. The initial conversion price of the Notes represents a premium of approximately 40% over the last reported sale of $12.90 per share of the Company's Class A Common Stock on February 4, 2021. The conversion rate and conversion price will be subject to customary adjustments upon the occurrence of certain events in accordance with the terms of the Indenture.

The Company recorded $21,338 related to deferred financing costs of the Notes. During the year ended December 31, 2021, the Company amortized under the effective interest rate method $3,811 of deferred financing costs.

The Notes are the Company’s senior, unsecured obligations and are (i) equal in right of payment with the Company’s existing and future senior, unsecured indebtedness; (ii) senior in right of payment to the Company’s existing and future indebtedness that is expressly subordinated to the Notes; (iii) effectively subordinated to the Company’s existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness; and (iv) structurally subordinated to all existing and future indebtedness and other liabilities, including the Company’s trade payables, and (to the extent the Company is not a holder thereof) preferred equity, if any, of the Company’s subsidiaries.

(in thousands, except share/unit data and per share/unit amounts)

The Company may, at its option, redeem some of the Notes, in whole or in part, at the applicable redemption price as set forth in the Indenture.

If certain corporate events that constitute a “Fundamental Change” (as defined in the Indenture) occur, then, noteholders may require the Company to repurchase their Notes at a cash repurchase price equal to the principal amount of the Notes to be repurchased, plus accrued and unpaid special interest, if any. The definition of Fundamental Change includes certain business combination transactions involving the Company and certain de-listing events with respect to the Company’s Class A common stock.

The Notes have customary provisions relating to the occurrence of an “Event of Default” (as defined in the Indenture), which include the following: (i) a default by the Company in the payment when due (whether at maturity, upon redemption or repurchase upon fundamental change or otherwise) of the principal of, or the redemption price or fundamental change repurchase price for, any Note (ii) a default by the Company for 30 days in the payment when due of special interest, if any, on any Note; (iii) the Company’s failure to send certain notices under the Indenture within specified periods of time; (iv) a default by the Company in its obligation to convert a Note in accordance with the Indenture upon the exercise of the conversion right with respect thereto, if such default is not cured within three business days after its occurrence; (v) the Company’s failure to comply with certain covenants in the Indenture relating to the Company’s ability to consolidate with or merge with or into, or sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Company and its subsidiaries, taken as a whole, to another person; (vi) a default by the Company in its other obligations or agreements under the Indenture or the Notes (other than a default set forth in clauses (i), (ii), (iii), (iv) or (v) above) if such default is not cured or waived within 60 days after written notice is given in accordance with the Indenture; (vii) certain defaults by the Company or any of its significant subsidiaries with respect to indebtedness for borrowed money of at least $50,000; and (viii) certain events of bankruptcy, insolvency and reorganization involving the Company or any of the Company’s significant subsidiaries.

If an Event of Default involving bankruptcy, insolvency or reorganization events with respect to the Company (and not solely with respect to a significant subsidiary of the Company) occurs, then the principal amount of, and all accrued and unpaid special interest, if any, on, all of the Notes then outstanding will immediately become due and payable without any further action or notice by any person. If any other Event of Default occurs and is continuing, then, the Trustee, by notice to the Company, or noteholders of at least 25% of the aggregate principal amount of Notes then outstanding, by written notice to the Company and the Trustee, may declare the principal amount of, and all accrued and unpaid special interest, if any, on, all of the Notes then outstanding to become due and payable immediately. However, notwithstanding the foregoing, the Company may elect, at its option, that the sole remedy for an Event of Default relating to certain failures by the Company to comply with certain reporting covenants in the Indenture consists exclusively of the right of the noteholders to receive special interest on the Notes for up to 180 days at a specified rate per annum not exceeding 0.50% on the principal amount of the Notes.

The Company used approximately $69,518 of the net proceeds from the Notes to fund the cost of entering into the capped call transactions described below. The Company used a portion of the remainder of the net proceeds from the offering to repay amounts owed under the HPS Credit Facility.

On February 4, 2021, in connection with the pricing of the Notes, the Company entered into privately negotiated capped call transactions (the “Base Capped Call Transactions”) with certain of the initial purchasers of the Notes and/or their respective affiliates and/or other financial institutions (the “Option Counterparties”). In addition, on February 9, 2021, in connection with First Greenshoe Exercise and on February 11, 2021, in connection with the Second Greenshoe Exercise, the Company entered into additional privately negotiated capped call transactions (collectively, and together with the Base Capped Call Transactions, the “Capped Call Transactions”) with the Option Counterparties. The Capped Call Transactions cover, subject to anti-dilution adjustments substantially similar to those applicable to the Notes, the number of shares of Class A common stock initially underlying the Notes. The Capped Call Transactions are expected generally to reduce potential dilution to the Class A common stock upon any conversion of the Notes and/or offset any potential cash payments the Company is required to make in excess of the principal amount of such converted Notes, as the case may be, with such reduction and/or offset subject to a cap.

The Capped Call Transactions are separate transactions entered into by the Company with each Option Counterparty, and are not part of the terms of the Notes and will not affect any noteholder’s rights under the Notes. Noteholders will not have any rights with respect to the Capped Call Transactions.

In connection with the issuance of the Notes, SmileDirectClub, Inc. entered into an intercompany convertible promissory note (“Intercompany Convertible Note”) with SDC Financial, LLC, whereby SmileDirectClub, Inc. provided the net proceeds from the issuance of the Notes to SDC Financial, LLC. The terms of the Intercompany Convertible Note mirrors the terms of the Notes issued by SmileDirectClub, Inc. The intent of the Intercompany Convertible Note is to maintain the parity of shares of Class A common stock with LLC Units as required by the SDC Financial LLC Agreement.

HPS Credit Facility

In May 2020, SDC U.S. SmilePay SPV (“SPV”), a wholly-owned special purpose subsidiary of the Company, entered into a Loan Agreement among SPV, as borrower, SmileDirectClub, LLC, as the seller and servicer, certain lenders, and HPS Investment Partners, LLC, as administrative agent and collateral agent, providing a five-year secured term loan facility to SPV in an initial aggregate maximum principal amount of $400,000, net of original issue discount of $12,000, with the ability to request incremental term loans of up to an additional aggregate principal amount of $100,000 with the consent of the lenders participating in such increase (the “HPS Credit Facility”).

The proceeds of the HPS Credit Facility were used to repay all outstanding amounts under the previous JPM Credit Facility and for working capital and other corporate purposes. In connection with the repayment, the Company paid $187 in fees and wrote-off the remaining unamortized loan costs of $1,594, both of which were included in loss from extinguishment of debt in the period in which the HPS Credit Facility was entered.

The Company recorded $11,784 related to deferred financing costs of the HPS Credit Facility in the second quarter of 2020. During the year ended December 31, 2021, the Company amortized under the effective interest rate method $536 of deferred financing costs. The remaining original issue discount is included in loss from extinguishment of debt in the accompanying consolidated statements of operations for the year ended December 31, 2021.

Outstanding loans under the HPS Credit Facility bore interest at a variable rate equal to three-month LIBOR (subject to a 1.75% per annum floor), plus 7.50% per annum payable in cash, plus 3.25% per annum payable in kind or, at the Company’s election, wholly or partially in cash.

Subject to certain exceptions, the HPS Credit Facility was secured by first-priority security interests in SPV’s assets, which consisted of certain receivables, cash governed by a control agreement with HPS, intellectual property and related assets. SPV’s obligations under the Loan Agreement were guaranteed on a limited basis by SmileDirectClub, LLC and SDC Financial LLC.

The HPS Credit Facility contained various restrictions, covenants, ratios and events of default, including:

•SPV had limitations on consolidations, creation of liens, incurring additional indebtedness, dispositions of assets, investments and paying dividends or other distributions.

•SDC Financial LLC, its consolidated subsidiaries and certain originator entities had to maintain minimum monthly liquidity of $100,000 and are subject to additional leverage ratios upon the occurrence of additional debt.

•SDC Financial LLC was subject to a consolidated leverage ratio measured as of the end of each fiscal quarter beginning March 31, 2022, to be calculated based on annualized EBITDA for the first three quarters of 2022, and thereafter, to be calculated based on EBITDA during the trailing four fiscal quarters for the relevant period.

The HPS Credit Facility could have been refinanced during the first year, provided that SPV would be required to pay the amount of interest that would have accrued during the remainder of the first year, plus 4% of the principal amount prepaid; and after the first year, for a fee of 4% of the principal amount prepaid, with the prepayment fee decreasing each year to 3% in the third year, 2% in the fourth year and 1% in the fifth year.

On March 29, 2021, the HPS Credit Facility was paid in full and terminated. In connection with the repayment, the unamortized loan costs, the unaccreted warrant value, and the prepayment fee described above are recorded as a loss on extinguishment of debt in the accompanying consolidated statements of operations.

HPS Warrants

In connection with the HPS Credit Facility, the Company issued warrants (“HPS Warrants”) to affiliates of HPS Investment Partners, LLC exercisable at any time into an aggregate of 3,889,575 shares of the Company’s Class A common stock, which amounted to 1% of the Company’s total outstanding Class A and Class B common stock, including the HPS Warrants, as of the closing date of the HPS Credit Facility, at an exercise price of $7.11 per share, payable in cash or pursuant to a cashless exercise. The HPS Warrants were recorded at their initial fair value of $17,620 and included within stockholders’ equity. The termination and payoff of the HPS Credit Facility did not impact the HPS Warrants.

Align Redemption Promissory Note

In connection with the required redemption of Align’s 20,710 Pre-IPO Units described in Note 16, the Company entered into a promissory note with Align Technology, Inc. (“Align”). Under the terms of the promissory note, the Company was scheduled to make monthly payments of $2,311 to Align through March 2021. The promissory note bore annual interest of 2.52% which is included in the consolidated statement of operations. As of December 31, 2021, the Company has $0 outstanding under this promissory note.

Note 11—Noncontrolling Interests

SDC Inc. is the sole managing member of SDC Financial, and consolidates the financial results of SDC Financial. Therefore, SDC Inc. reports a noncontrolling interest based on the common units of SDC Financial held by the Continuing LLC Members. Changes in SDC Inc.’s ownership interest in SDC Financial, while SDC Inc. retains its controlling interest in SDC Financial, are accounted for as equity transactions. As such, future redemptions or direct exchanges of LLC Units by the Continuing LLC Members will result in a change in ownership and reduce or increase the amount recorded as noncontrolling interest and increase or decrease additional paid-in capital when SDC Financial has positive or negative net assets, respectively. As of December 31, 2021, SDC Inc. had 119,280,781 shares of Class A common stock outstanding, which

(in thousands, except share/unit data and per share/unit amounts)

resulted in an equivalent amount of ownership of LLC Units by SDC Inc. As of December 31, 2021, SDC Inc. had a 30.7% economic ownership interest in SDC Financial.

Note 12—Variable Interest Entities

Upon completion of the IPO, SDC Inc. became the managing member of SDC Financial with 100% of the management and voting power in SDC Financial. In its capacity as managing member, SDC Inc. has the sole authority to make decisions on behalf of SDC Financial and bind SDC Financial to signed agreements. Further, SDC Financial maintains separate capital accounts for its investors as a mechanism for tracking earnings and subsequent distribution rights. Accordingly, management concluded that SDC Financial is determined to be a limited partnership or similar legal entity as contemplated in ASC 810.

Furthermore, management concluded that SDC Inc. is SDC Financials’ primary beneficiary. As the primary beneficiary, SDC Inc. consolidates the results of SDC Financial for financial reporting purposes under the variable interest consolidation model guidance in ASC 810.

SDC Inc.’s relationship with SDC Financial results in no recourse to the general credit of SDC Inc. SDC Financial and its consolidated subsidiaries represents SDC Inc.’s sole investment. SDC Inc. shares in the income and losses of SDC Financial in direct proportion to SDC Inc.’s ownership percentage. Further, SDC Inc. has no contractual requirement to provide financial support to SDC Financial.

SDC Inc.’s financial position, performance and cash flows effectively represent those of SDC Financial as of and for the years ended December 31, 2021 and 2020. Prior to the IPO and Reorganization Transactions, SDC Inc. was not impacted by SDC Financial.

Note 13—Incentive Compensation Plans

In connection with the IPO, the Company adopted the 2019 Omnibus Incentive Compensation Plan (the “2019 Plan”) in August 2019. The Company’s board of directors or the compensation committee of the board of directors, acting as plan administrator, administers the 2019 Plan and the awards granted under it. The Company reserved a total of 38,486,295 shares of Class A common stock for issuance pursuant to the 2019 Plan. The Company currently has two types of share-based compensation awards outstanding under the 2019 Plan: Class A common stock options (“Options”) and Class A restricted stock units (“RSUs”), including those issued pursuant to IBAs.

Class A Common Stock Options

Options activity was as follows during the year ended December 31, 2021:

	Number of Options	Weighted Average Exercise Price		Weighted Average Remaining Contractual Term	Aggregate Intrinsic Value
Outstanding at December 31, 2020	1,679,339	$	23.00	8.7	$	—
Granted	50,000	12.21		9.1	—
Exercised	—	—		—	—

Exercisable at December 31, 2021	597,816	$	23.00	7.7	$	—

The Company estimates fair value of the Options using the Black-Scholes option pricing model. Inputs to the Black-Scholes option pricing model for awards issued during the years ended December 31, 2021, include an expected dividend

SmileDirectClub, Inc.

(in thousands, except share/unit data and per share/unit amounts)

yield of 0.0%, expected volatility of 65.6%, risk-free interest rate of 0.8% and an expected term of 6.3 years, pursuant to time-based vesting terms, resulting in a weighted average fair value of $8.17 per Option. As of December 31, 2021, unrecognized compensation expense related to the Options was $4,183. This expense is expected to be recognized over a weighted average period of 0.9 years.

Expected dividend yield - An increase in the expected dividend yield would decrease compensation expense.

Expected volatility - This is a measure of the amount by which the price of the equity instrument has fluctuated or is expected to fluctuate. The expected volatility was based on the historical volatility of a group of guideline companies. An increase in expected volatility would increase compensation expense.

Risk-free interest rate - This is the U.S. Treasury rate as of the measurement date having a term approximating the expected life of the award. An increase in the risk-free interest rate would increase compensation expense.

Expected term - The period of time over which the awards are expected to remain outstanding. The Company estimates the expected term as the mid-point between actual or expected vesting date and the contractual term. An increase in the expected term would increase compensation expense.

Restricted Stock Units

Incentive Bonus Awards

The Company has IBA agreements with several key employees to provide a bonus payment in the event of a liquidation event as defined in each agreement. The bonus amounts are calculated based on the value of the Company at the time of the liquidation event, less an amount determined upon the employee entering into the agreement. The right to the payment generally vests annually over a five-year period, with certain liquidation events resulting in an acceleration of the vesting period. As the vesting of these awards was contingent on a liquidation event, no amounts were required to be recorded prior to a liquidation event. The IBA agreements were modified in August 2019 to accelerate certain vesting conditions upon a liquidation event and to modify the settlement terms, whereby the Company settled the vested portion of each IBA in 50% shares of Class A common stock and/or vested RSUs and 50% cash, of which approximately 80% of the cash (40% of the total vested portion of the award) that the IBA holders would have otherwise received was withheld by the Company to fulfill tax withholding obligations and the remainder was paid out to IBA holders upon the occurrence of a liquidation event. As a result of the modification and the occurrence of a liquidation event through the IPO, the Company recorded equity-based compensation expense of $316,959, equivalent to the amount of IBAs vested at the time of the IPO, in the form of cash, 5,654,078 shares of Class A common stock and 2,199,453 vested RSUs to be released over a period of six to twenty-four months following the date of the IPO. The unvested portion of the IBAs are represented in the form of unvested RSUs that will vest, subject to the holders’ continued employment, over a period generally ranging from 2 years to 4 years.

Non-IBA Restricted Stock Units

The Company granted RSUs to certain team members that generally vest annually over two to three years or after three years from the date of grant, subject to the recipient’s continued employment or service to the Company through each vesting date.

As of December 31, 2021, unrecognized compensation expense related to unvested IBA and non-IBA RSUs was $38,812. This expense is expected to be recognized over a weighted average period of 2.4 years.

Employee Stock Purchase Plan

The SmileDirectClub, Inc. team member Stock Purchase Plan (“SPP”) was initiated in November 2019. Under the SPP, the Company is authorized to issue up to 5,772,944 shares of its Class A common stock to qualifying employees. Eligible team members may direct the Company, during each six months option period, to withhold up to 30% of their base salary and commissions, the proceeds from which are used to purchase shares of Class A common stock at a price equal to the lesser of 85% of the closing market price on the exercise date or the grant date. For accounting purposes, the SPP is considered a compensatory plan such that the Company recognizes equity-based compensation expense based on the fair value of the options held by the employees to purchase the Company’s shares.

Summary of Equity-Based Compensation Expense

The Company recognized compensation expense of $44,628, $44,903 and $350,122 for the years ended December 31, 2021, 2020 and 2019, respectively. Amounts are included in general and administrative expense on the consolidated statements of operations.

Note 14—Earnings (Loss) Per Share

Basic earnings per share of Class A common stock is computed by dividing net loss attributable to SDC Inc. by the weighted-average number of shares of Class A common stock outstanding during the period. Diluted earnings per share of Class A common stock is computed by dividing net loss attributable to SDC Inc., adjusted for the assumed exchange of all potentially dilutive LLC Units for Class A common stock, by the weighted-average number of shares of Class A common stock outstanding adjusted to give effect to potentially dilutive elements. Prior to the IPO, the SDC Financial membership structure included Pre-IPO Units, some of which were profits interests. The Company analyzed the calculation of earnings per unit for periods prior to the IPO and determined that it resulted in values that would not be meaningful to the users of these consolidated financial statements. Therefore, the basic and diluted earnings per share for the year ended December 31, 2019, represents only the period from September 11, 2019 to December 31, 2019, which represents the period wherein the Company had outstanding Class A common stock.

Shares of the Company’s Class B common stock do not participate in the earnings or losses of the Company and are therefore not participating securities. As such, separate presentation of basic and diluted earnings (loss) per share of Class B common stock under the two-class method has not been presented.

Due to their anti-dilutive effect, the following securities have been excluded from diluted net earnings (loss) per share in the periods presented:

(1) In connection with the issuance of the Notes, the Company entered into Capped Call Transactions, which were not included for purposes of calculating the number of diluted shares outstanding, as their effect would have been anti-dilutive. The Capped Call Transactions are expected to reduce the potential dilution to the Company’s common stock (or, in the event a conversion of the Notes is settled in cash, to reduce its cash payment obligation) in the event that at the time of conversion of the Notes the Company’s common stock price exceeds the conversion price of the Notes.

Note 15—Employee Benefit Plans

The Company has a defined contribution retirement plan under Section 401(k) of the Internal Revenue Code of 1986, as amended, that 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. For the years ended December 31, 2021, 2020 and 2019 the Company matched 100% of employees’ salary deferral contributions up to 3% and 50% of employees’ salary deferral contributions from 3% to 5% of employees’ eligible compensation. The Company contributed $3,141, $3,202 and $2,707 to the 401(k) plan for the years ended December 31, 2021, 2020 and 2019, respectively.

Note 16—Related Party Transactions

Products and Services

The Company is affiliated through common ownership by the Company’s Chairman and Chief Executive Officer, with several other entities (‘‘Affiliates”). Certain Affiliates incur (or previously incurred) costs related to the Company, including travel costs, certain senior management personnel costs, freight, and rent, the most significant of which is freight. The Company reimbursed $0, $0 and $7,433 of freight incurred through an Affiliate during the years ended December 31, 2021, 2020 and 2019, respectively, which is included in cost of revenues. These costs incurred by Affiliates related to the Company are billed at actual cost to the Company by the Affiliates.

In addition, the Company paid one of the Affiliates $0, $0 and $1,255 in management fees for the years ended December 31, 2021, 2020 and 2019, respectively, which is included in general and administrative expenses. These fees include charges relating to several individuals who provide senior leadership to the Company as well as certain other services. Certain of these individuals have been granted IBUs, which have resulted in equity-based compensation expense (see Note 13).

The Company purchased legal services from a law firm where a partner is an immediate family member of an executive officer and director of the Company. Fees paid for services totaled $5,806, $5,790 and $1,716 for the years ended December 31, 2021, 2020 and 2019, respectively.

The Company was party to a Strategic Supply Agreement with Align, a former equityholder of the Company, in which the Company had the option to purchase aligners from Align at a price that varies with the level of product purchased. While the majority of the Company’s aligners were manufactured in-house, the Company did purchase aligners under this agreement during the first quarter of 2019. Additionally, the Company purchases oral digital imaging equipment from Align. For the years ended December 31, 2021, 2020 and 2019, purchases from Align of equipment were $0, $0 and $6,025, respectively, and purchases of aligners included in cost of revenues were $0, $0 and $7,659, respectively.

In February 2020, the Company completed the purchase of a private aircraft from Camelot SI Leasing, LLC, an entity indirectly under common control with Camelot, for $3,400, the appraised value of the aircraft.

Distribution Payable

In August 2019, SDC Financial declared a distribution of $43,400 less any amount determined to be due and payable to Align in connection with the Align arbitration proceedings to the pre-IPO investors. The arbitration proceedings were finalized and this amount plus accrued interest was paid to Align in March 2021.

Note 17—Commitments and Contingencies

Legal Matters

In the ordinary course of conducting its business, the Company is involved, from time to time, in various contractual, product liability, intellectual property, and other claims and disputes incidental to its business. Litigation is subject to many uncertainties, the outcome of individual litigated matters is not predictable with assurance, and it is reasonably possible that some of these matters may be decided unfavorably to the Company and could have a material impact on the financial statements. In addition, the Company periodically receives communications from state and federal regulatory and similar agencies inquiring about the nature of its business activities, licensing of professionals providing services, and similar matters. Such matters are routinely concluded with no financial or operational impact on the Company.

From September to December 2019, a number of purported stockholder class action complaints were filed in the U.S. District Court for the Middle District of Tennessee and in state courts in Tennessee, Michigan, and New York against the Company, members of the Company’s board of directors, certain of its current or former officers, and the underwriters of its IPO. The following complaints have been filed to date: Mancour v. SmileDirectClub, Inc., 19-1169-IV (TN Chancery Court filed 9/27/19), Vang v. SmileDirectClub, Inc., 19c2316 (TN Circuit Court filed 9/30/19), Fernandez v. SmileDirectClub, Inc., 19c2371 (TN Circuit Court filed 10/4/19), Wei Wei v. SmileDirectClub, Inc., 19-1254-III (TN Chancery Court filed 10/18/19), Andre v. SmileDirectClub, Inc., 19-cv-12883 (E.D. Mich. filed 10/2/19), Ginsberg v. SmileDirectClub, Inc., 19-cv-09794 (S.D.N.Y. filed 10/23/19), Franchi v. SmileDirectClub, Inc., 19- cv-962 (M.D. Tenn. filed 10/29/19), Nurlybayev v. SmileDirectClub, Inc., 19-177527-CB (Oakland County, MI Circuit Court filed 10/30/19), Sasso v. Katzman, et al., No. 657557/2019 (NY Supreme Court filed 12/18/19), Nurlybayev v. SmileDirectClub, Inc., No. 652603/2020 (Supreme Ct. N.Y. Cty. filed June 19, 2020). The complaints all allege, among other things, that the registration statement filed with the SEC on August 16, 2019, and accompanying amendments, and the Prospectus filed with the SEC on September 13, 2019, in connection with the Company’s initial public offering were inaccurate and misleading, contained untrue statements of material facts, omitted to state other facts necessary to make the statements made not misleading, and omitted to state material facts required to be stated therein. The complaints seek unspecified money damages, other equitable relief, and attorneys’ fees and costs. All the actions are in the preliminary stages. The Company denies any alleged wrongdoing and is vigorously defending against these actions.

In December 2019, the Fernandez, Vang, Mancour and Wei Wei actions were consolidated and re-captioned In re SmileDirectClub, Inc. Securities Litigation, 19-1169-IV (Davidson County, TN Chancery Court). Plaintiffs filed a consolidated amended complaint on December 20, 2019, and Defendants moved to stay or dismiss the action on February 10, 2020. On June 4, 2020, the court denied that motion. Defendants subsequently moved for permission to seek an interlocutory appeal of that decision. On June 22, 2020, the court granted that motion. On August 3, 2020, Defendants filed an application for interlocutory appeal with the court of appeals, which was denied. On September 21, 2020, Defendants filed an application for interlocutory appeal with the Tennessee Supreme Court, which was denied. On October 2, 2020, Plaintiffs moved for class certification, which Defendants opposed on January 25, 2021. On April 28, 2021, the court ruled in favor of the Plaintiffs class certification. The Company filed its notice of appeal on May 4, 2021. That appeal was fully briefed and has been pending since oral argument on December 2, 2021. All trial court proceedings are stayed during the pendency of the appeal.

The Andre and Ginsberg actions were transferred to the U.S. District Court for the Middle District of Tennessee, where they were consolidated with the Franchi action. Plaintiffs filed a consolidated amended complaint on February 21, 2020, and Defendants moved to dismiss the action on March 23, 2020. That motion remains pending. While that motion was pending, the parties stipulated to allow Plaintiffs to file a further amended complaint, which Plaintiffs filed on March 31, 2021. Defendants’ motion to dismiss the new complaint was due on or before May 14, 2021. That motion was fully briefed as of July 19, 2021 and remains pending.

In the Nurlybayev action, on January 10, 2020, certain Defendants, including the Company, moved to be dismissed from the action for lack of personal jurisdiction and the remaining Defendants moved to dismiss or stay the entire action in favor of the related actions pending in Tennessee. On February 26, 2020, the Court granted Defendants' motion to dismiss the entire action in favor of the related actions pending in Tennessee. On June 19, 2020, Plaintiff Nurlybayev filed a substantially similar action in New York state court. On August 21, 2020, Defendants filed a motion to dismiss that action, which the Court granted on May 25, 2021. Plaintiff has filed a notice of appeal. Plaintiff perfected his appeal on January 21, 2022 and briefing on the appeal is in progress.

In the Sasso action, Plaintiff agreed to stay the action pending resolution of any motions to dismiss in any of the related actions. The Court so-ordered the parties’ stipulation to that effect on January 22, 2020.

In November and December 2019 and March 2020, three stockholder derivative actions were filed against the members of the Company’s board of directors, certain of the Company’s current and former officers and related entities: Doris Shenwick Trust v.

Derivative Litigation, C.A. No. 2019-0940-MTZ (Delaware Chancery Court) and Plaintiffs filed a consolidated amended complaint on April 8, 2020. The complaint alleges, among other things, that the defendants breached their fiduciary duties by allowing the Prospectus filed with the SEC on September 13, 2019, in connection with the Company's initial public offering, to contain materially misleading statements and by approving that the IPO proceeds be used to acquire Units and Common Stock from selling directors in connection with the IPO at an allegedly inflated price. The complaint also alleges that certain related entities aided and abetted the directors' alleged breach of fiduciary duties by selling their Common Stock and LLC Units and profiting from those sales. The complaint also alleges that the directors and related entities were unjustly enriched. The complaint seeks, among other things, disgorgement from the director and entity defendants. The Company denies any alleged wrongdoing and moved to dismiss the action. Briefing on the motion to dismiss was complete on November 6, 2020. A hearing on the motion to dismiss was held on February 17, 2021. The Court granted the motion to dismiss on May 28, 2021 and dismissed the complaint. On June 24, 2021, plaintiffs filed a Notice of Appeal. The parties submitted appellate briefing and on December 8, 2021, oral argument was held before the Delaware Supreme Court. On January 6, 2022, the Delaware Supreme Court affirmed dismissal of the derivative action on the basis of and for the reasons assigned by the Court of Chancery.

In September 2019, a putative class action on behalf of a consumer and three orthodontists was brought against the Company in the U.S. District Court for the Middle District of Tennessee, Ciccio, et al. v. SmileDirectClub, LLC, et al., Case No. 3:19-cv-00845 (M.D. Tenn.). The Plaintiffs assert claims for breach of warranty, false advertising under the Lanham Act, common law fraud, and various state consumer protection statutes relating to the Company’s advertising. Following a proactive voluntary dismissal by the majority of consumer plaintiffs, one consumer has since sought to rejoin the Middle District of Tennessee litigation or, in the alternative, to intervene, which the Court granted. That ruling has been appealed, and the Court stayed the consumer claims pending the appeal. On June 25, 2021, the appellate court reversed the district court and remanded with instructions to order the intervening plaintiff to mandatory binding arbitration. All remaining consumer claims remain stayed. Litigation is in the discovery stage. On October 13, 2021, the Court entered an Amended Scheduling Order, effectively staying merits discovery, and setting deadlines of March 30, 2022, to complete class certification fact discovery and September 2, 2022, to complete briefing on motions regarding class certification. The Company denies any alleged wrongdoing and intends to defend against this action vigorously.

Some state dental boards have established new rules or interpreted existing rules in a manner that limits or restricts the Company’s ability to conduct its business as currently conducted in other states or have engaged in conduct so as to otherwise interfere with the Company’s ability to conduct its business. We have filed actions in federal court in Alabama, Georgia, and California against the state dental boards in those states, alleging violations by the dental boards of various laws, including the Sherman Act and the Commerce Clause. While a national orthodontic association has filed Amicus Briefs in support of the dental boards in both the Georgia and Alabama litigations and has filed a motion to do the same in California (which motion was denied), the FTC and DOJ have filed joint Amicus Briefs in support of the Company in both the Alabama and Georgia matters. The California matter was amended, and an order of dismissal was entered on July 7, 2020. The Company filed notice of appeal on July 17, 2020, and the FTC and DOJ filed a joint Amicus Brief in support of the Company. Oral argument was held on July 26, 2021, with the FTC and DOJ arguing in support of the Company at oral argument as well. The appellate court has not yet issued its ruling. Both the Alabama and Georgia matters were then sent to the 11th Circuit Court of Appeals as a result of the dental boards in both states appealing the lower court’s decisions. Oral argument before the 11th Circuit Court of Appeals occurred in the Georgia matter on May 20, 2020, and in the Alabama matter on July 8, 2020. The FTC and DOJ participated in oral arguments in support of the Company. The DOJ’s antitrust chief presented in the Alabama matter. On August 11, 2020, the 11th Circuit Court of Appeals affirmed the Georgia district court’s denial of the board members’ motion to dismiss. On December 8, 2020, the 11th Circuit Court of Appeals voted to have a rehearing en banc. The FTC and DOJ filed an amicus and participated in oral argument that was held on February 23, 2021. On July 20, 2021, the 11th Circuit Court of Appeals ruled in the Company’s favor, finding that the Georgia Dental Board did not have an interlocutory right of appeal and therefore denied the Georgia Board’s appeal. On July 29, 2021, the 11th Circuit Court of Appeals also denied the Alabama Dental Board’s appeal. Both cases were remanded to the respective District Courts to proceed accordingly into the discovery phase.

On November 22, 2021, the Georgia Board filed a motion to dismiss in the Northern District of Georgia. On January 6, 2022, a hearing was held on the motion to dismiss. The parties await a final order and discovery is ongoing.

On August 17, 2021, the Alabama Dental Board and the Company entered into a tentative settlement agreement, subject to the FTC’s proposed Consent Order being entered into by the Board, precluding the Alabama Dental Board from requiring onsite supervision for scanning by doctors in SmileShops. On September 28, 2021, the FTC issued its press release and memorandum regarding its proposed Consent Order with the Alabama Dental Board which precludes the Board from engaging in conduct intended to preclude teledentistry in the State of Alabama or to preclude dentists and orthodontists from using the Company’s teledentistry platform to treat patients. On December 22, 2021, the Consent Order was finalized, and the District Court in Alabama thereafter entered its order approving the joint motion for dismissal of the lawsuit per the terms of the settlement reached between the parties.

On July 12, 2021, the Australian Competition & Consumer Commission filed an Originating Application against SmileDirectClub, LLC and the Company’s Australian affiliate SmileDirectClub Aus Pty Ltd. The Originating Application alleges certain misstatements by the Company in connection with the availability of consumers having the ability to have private health care coverage cover a portion of their costs when seeking treatment through the Company’s telehealth platform. The Company has denied any wrongdoing and has filed its Concise Response to the Statement of Claim. Should the matter not be resolved, trial has been scheduled to commence on April 17, 2023.

In March 2019, a final arbitration award was issued in an arbitration proceeding brought by the Company alleging that one of our former members, Align, violated certain restrictive covenants set forth in its operating agreement. The arbitrator ruled that Align breached both the non-competition and confidentiality provisions of the Company’s operating agreement and that, as a result, Align was required to close its Invisalign Stores, return all of the Company’s confidential information, and sell its membership units to the Company or certain of its pre-IPO unitholders for an amount equal to the balance of Align’s capital account as of November 2017. The arbitrator also extended the non-competition period to which Align is subject through August of 2022 and prohibited Align from using the Company’s confidential information in any manner going forward. The Company paid Align $54,000, pursuant to a promissory note payable over 24 months through March 2021, in full redemption of Align’s membership units pursuant to this ruling. The ruling has been confirmed in its entirety in the circuit court of Cook County, Chicago, Illinois, but Align continued to object to the purchase price and repurchase documentation despite the arbitration ruling and its confirmation, and filed a subsequent arbitration proceeding disputing the $54,000 redemption amount and seeking an additional $43,400. Arbitration was held in December 2020. The arbitrator reached final decision in March 2021 and the Company paid Align the remaining amount of $43,400 (which it had reserved) plus accrued interest.

In December 2020, a class action complaint was filed in the Illinois state court: Stacy Benbow et al. v. SmileDirectClub, Inc. et al., 2020 CH 07269 (Cook County Circuit Court filed 12/14/20). The complaint alleges violations of the Telephone Consumer Protection Act and seeks to represent a nationwide class of similarly situated persons. The complaint seeks injunctive relief, statutory damages, and attorneys’ fees and costs. A tentative settlement was approved by the court and the Company has recorded an estimated loss of $4,800 related to such tentative settlement. Notice to the class was sent on March 20, 2021, and final approval was set for May 19, 2021. On May 19, 2021, the final approval was granted by the Cook County Circuit Court. The final cost of the settlement was approximately $4,000.

Tax Receivable Agreement

As described in Note 9, the Company is a party to the Tax Receivable Agreement pursuant to which SDC Inc. is contractually committed to pay the Continuing LLC Members 85% of the amount of any tax benefits that SDC Inc. actually realizes, or in some cases is deemed to realize, as a result of certain transactions. The Company is not obligated to make any payments under the Tax Receivable Agreement until the tax benefits associated with the transactions that gave rise to the payments are realized. TRA Payments are contingent upon, among other things, (i) generation of future taxable income over the term of the Tax Receivable Agreement and (ii) future changes in tax laws. If the Company does not generate sufficient taxable income in the aggregate over the term of the Tax Receivable Agreement to utilize the tax benefits, then it will not be required to make the related TRA Payments. During the years ended December 31, 2021 and 2020, the Company recognized

SmileDirectClub, Inc.

Notes to Consolidated Financial Statements (Continued)

For the year ended December 31, 2021
(in thousands, except share/unit data and per share/unit amounts)

no liabilities relating to its obligations under the Tax Receivable Agreement, after concluding that it was not probable that the Company would have sufficient future taxable income over the term of the Tax Receivable Agreement to utilize the related tax benefits. There were no transactions subject to the Tax Receivable Agreement for which the Company recognized the related liability, as the Company concluded that it would not have sufficient future taxable income to utilize all of the related tax benefits.

Other Tax Matters

We operate in numerous jurisdictions in which taxing authorities may challenge our position with respect to income and non-income-based taxes. We routinely receive inquiries and may also from time to time receive challenges or assessments from these taxing authorities. With respect to non-income-based taxes, we recognize liabilities when we believe it is probable that amounts will be owed to the taxing authorities and such amounts are estimable. For example, in most countries we charge and remit Value Added Tax (“VAT”) when procuring goods and services, or providing services, within the normal course of business. VAT receivables are established in jurisdictions where input VAT exceeds output VAT and are recoverable through the filing of refund claims. These receivables have inherent audit and collection risks unique to the specific jurisdictions that evaluate our refund claims. We have received a challenge from a non-US taxing authority for VAT related to certain sales made and services provided by certain of the Company’s subsidiaries. The Company believes these transactions are exempt from VAT and has filed legal actions challenging the taxing authority’s application of VAT to them. Discussions on these matters are ongoing. The Company believes its interpretation of these VAT rules is appropriate, and that it will be successful in its challenge against the taxing authority’s assessments. Accordingly, the Company does not believe it is probable that it will incur a loss related to these matters. However, the interpretation and application of these VAT rules is an unsettled issue, and the resolution of tax and regulatory matters is unpredictable. If it is determined in these proceedings that VAT applies to some or all of these various transactions, the Company could incur a charge that ranges between zero and $17,900 for these matters, including any interest and penalties associated with these matters and the amount, if any, of VAT the Company might subsequently recover related to its input costs.

Note 18—Segment Reporting

The Company provides aligner products. The Company’s chief operating decision maker (“CODM”) views the operations and manages the business primarily on a consolidated basis, however, the CODM regularly evaluates, monitors, and makes operational decisions based on the results of operations segmented between North America (defined as the U.S. and Canada) and Rest of World. For the year ended December 31, 2021, approximately 82.4% of the Company’s revenues were generated by sales within North America, and substantially all of its net property, plant and equipment was within North America. Below are the tabular results of operations summarized at the revenue and operating loss level for North America and the Rest of World for the years ended December 31, 2021 and 2020. For the year ended December 31, 2019, the results of operations were not segregated and presented to the chief operating decision maker at this same level and therefore are not presented herein.

Note 21—Subsequent Events

On January 24, 2022, the Company announced that following an evaluation of its business and the continuing macroeconomic factors impacting consumers, the Company is taking specific actions that will focus efforts on supporting the key growth initiatives that will produce the highest return on investment. These initiatives include the expansion of its professional channel, the SmileDirectClub Partner Network; innovations to its aligner products so as to allow the Company to capture greater market share of the teen and higher-household income demographics; its burgeoning oral care product business; and SmileShop growth in markets with strong consumer demand. Expansion into new international markets will be paused while the global economy recovers from pandemic and macroeconomic pressures that have contributed to challenging operating environments.

In connection with these operational changes, the Company announced it has suspended operations in Mexico, Spain, Germany, Netherlands, Austria, Hong Kong, Singapore and New Zealand. The Company will continue to operate in and scale its presence in the United States, Canada, United Kingdom, Ireland, France and Australia. With these changes, the Company initiated a reduction in workforce to right-size its operating structure so it is tailored to the countries in which the Company will continue to operate and focus.

Exhibit 10.12

Summary of SmileDirectClub, Inc.

Compensation for Non-Employee and Non-Affiliated Directors

(as of February 22, 2022)

Non-employee and non-affiliated directors of SmileDirectClub, Inc. (the “Company”) will receive compensation for their service as follows:

•Each non-employee and non-affiliated director of the Company is eligible to receive an annual grant of restricted stock units (“RSUs”), with a grant date fair value of $300,000; for 2022, in order to transition the grant cycle to coincide with the Company’s annual stockholder meetings, each such director will receive an annual grant of RSUs on April 1, 2022, with a grant date fair value of $350,000 (the “2022 Annual Grant Value”), which grant will vest on the earlier of June 1, 2023 or the day before the date of the Company’s annual meeting of stockholders for 2023 (such earlier date, the “Vesting Date”), subject to the director’s continued service on the Company’s board of directors (“Board”) through the Vesting Date.

•Each new non-employee and non-affiliated director of the Company will receive a prorated initial grant of RSUs upon joining the Board to be determined based on the annual grant value; for 2022, such prorated grant will be determined by (i) multiplying the number of months remaining following the date of grant, including the onboarding month, through the Vesting Date, by the value of the annual grant, and (ii) dividing by 14, which grant will vest on the Vesting Date, subject to the director’s continued service on the Board through the Vesting Date.

•Non-employee and non-affiliated directors of the Company may elect to receive their annual RSU grant in the form of a restricted stock award, in lieu of RSUs, with the same value and vesting terms as the RSU grants.

The RSU awards (or restricted stock awards, as the case may be) are also subject to full vesting acceleration upon a change in control. Each such director is entitled to reimbursement for all out-of-pocket expenses incurred in connection with attending each meeting of the Board and any committee thereof.

The Company is engaged by its network of doctors to provide a suite of non-clinical administrative support services, including access to and use of its SmileCheck platform, as a dental support organization. For purposes of these Notes to Consolidated Financial Statements, the Company’s affiliated network of dentists and orthodontists is included in the definition of “we,” “us,” “our,” and the “Company” as it relates to any clinical aspect of the member’s treatment. All of the Company’s manufacturing operations are directly or indirectly conducted by Access Dental Lab, LLC (“Access Dental”), one of its operating subsidiaries.

SmileDirectClub is an oral care company and creator of the first MedTech platform for teeth straightening. Through the Company’s cutting-edge teledentistry technology and vertically integrated model, it is revolutionizing the oral care industry, from clear aligner therapy to its affordable, premium oral care product line. SmileDirectClub’s mission is to democratize access to a smile each and every person loves by making it affordable and convenient for everyone. SmileDirectClub is headquartered in Nashville, Tennessee and operates in the U.S., Costa Rica, Puerto Rico, Canada, Australia, United Kingdom, France, and Ireland.

SDC Inc. is a holding company. Its sole material asset is its equity interest in SDC Financial which, through its direct and indirect subsidiaries, conducts all of the Company’s operations. SDC Financial is a Delaware limited liability company and wholly owns SmileDirectClub, LLC (“SDC LLC”) (a Tennessee limited liability company) and Access Dental (a Tennessee limited liability company). Because SDC Inc. is the managing member of SDC Financial, SDC Inc. indirectly operates and controls all of the business and affairs of SDC Financial and its subsidiaries.

Initial Public Offering

On September 16, 2019, SDC Inc. completed an initial public offering (“IPO”) of 58,537,000 shares of its Class A common stock at a public offering price of $23.00 per share. SDC Inc. received $1,286 million in proceeds, net of underwriting discounts and commissions. SDC Inc. used substantially all of the net proceeds after expenses to purchase newly-issued membership interest units from SDC Financial.

Reorganization Transactions

In connection with the IPO, the Company completed the following transactions (the “Reorganization Transactions”):

•the formation of SDC Inc. as a Delaware corporation to function as the ultimate parent of SmileDirectClub and a publicly traded entity;

•SDC Inc.’s acquisition of the pre-IPO membership interest units in SDC Financial (“Pre-IPO Units”) held by certain pre-IPO investors that are taxable as corporations for U.S. federal income tax purposes (“Blockers”), pursuant to a series of mergers (the “Blocker Mergers”) of the Blockers with wholly owned subsidiaries of SDC Inc., and the issuance by SDC Inc. to the equityholders of the Blockers shares of Class A common stock as consideration in the Blocker Mergers;

•the amendment and restatement of the SDC Financial’s limited liability company operating agreement (the “SDC Financial LLC Agreement”) to, among other things, modify the capital structure of SDC Financial by replacing the

different classes of Pre-IPO Units (including restricted Pre-IPO Units held by certain employees) with a single new class of membership interests of SDC Financial (“LLC Units”);

•the issuance to each of the pre-IPO investors previously holding Pre-IPO Units (including restricted Pre-IPO Units) of a number of shares of SDC Inc. Class B common stock equal to the number of LLC Units held by it;

•the issuance to certain employees of cash and shares of Class A common stock pursuant to their Incentive Bonus Agreements (“IBAs”); and

•the equitable adjustment, pursuant to their terms, of outstanding warrants to purchase Pre-IPO Units held by two service providers into warrants to acquire LLC Units (together with an equal number of shares of SDC Inc.’s Class B common stock).

Following the completion of the Reorganization Transactions and the IPO, SDC Inc. owned 26.9% of SDC Financial. Holders (other than SDC Inc.) of LLC Units following the consummation of the Reorganization Transactions and the IPO (“Continuing LLC Members”) owned the remaining 73.1% of SDC Financial.

SDC Inc. is the sole managing member of SDC Financial and, although SDC Inc. has a minority economic interest in SDC Financial, it has the sole voting power in, and controls the management of, SDC Financial. Accordingly, SDC Inc. consolidates the financial results of SDC Financial and reports a noncontrolling interest in its consolidated financial statements. As the Reorganization Transactions are considered transactions between entities under common control, the financial statements for periods prior to the IPO and Reorganization Transactions have been adjusted to combine the previously separate entities for presentation purposes.

In connection with the Reorganization Transactions and the IPO, the Company entered into a Tax Receivable Agreement (the “Tax Receivable Agreement”) with the Continuing LLC Members, pursuant to which SDC Inc. agreed to pay the Continuing LLC Members 85% of the amount of cash tax savings, if any, in U.S. federal, state, and local income tax or franchise tax that SDC Inc. actually realizes as a result of (a) the increases in tax basis attributable to exchanges of LLC Units by Continuing LLC Members and (b) tax benefits related to imputed interest deemed to be paid by SDC Inc. as a result of the Tax Receivable Agreement.

Basis of Presentation and Consolidation

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

The consolidated financial statements include the accounts of SDC Inc., which consolidates SDC Financial and its wholly-owned subsidiaries, as well as accounts of contractually affiliated professional corporations (“PCs”) managed by the Company.

The consolidated financial statements include the accounts of variable interest entities in which the Company is the primary beneficiary under the provisions of Accounting Standards Codification (‘‘ASC”) Topic 810, ‘‘Consolidation.” At December 31, 2021, the variable interest entities include 53 dentist owned PCs, and at December 31, 2020 the variable interest entities included 54 dentist owned PCs. The Company is a dental service organization and does not engage in the practice of dentistry. All clinical services are provided by dentists and orthodontists who are engaged as independent contractors or otherwise engaged by the dentist-owned PCs. The Company contracts with the PCs and dentists and orthodontists through a suite of agreements, including but not limited to, management services agreements, supply agreements, and licensing agreements, pursuant to which the Company provides the administrative, non-clinical management services to the PCs and independent contractors. The Company has the contractual right to manage the activities that most significantly impact the variable interest entities’ economic performance through these agreements without engaging in the corporate practice of dentistry. Additionally, the Company would absorb substantially all of the expected losses of these

entities should they occur. The accompanying consolidated statements of operations reflect the revenue earned and the expenses incurred by the PCs.

COVID-19 Pandemic

Although increasing rates of vaccinations across the globe and decreasing governmental restrictions have begun to lessen the impact of COVID-19, the Company continues to navigate the uncertain and unprecedented economic and operating conditions resulting from COVID-19 and its protracted duration. In response to COVID-19 and the related containment measures, the Company made the following operational changes beginning in the second quarter of 2020 to ensure the health and safety of its employees and its members: transitioned its team members, where possible, to a remote working environment; closed a portion of its SmileShops based on the Company’s real estate repositioning program as well as local public health guidelines and evolving customer behaviors and expectations; reconfigured its SmileShops and popup locations to reduce customer overlap in the waiting area and require touchless temperature screening upon arrival; heightened the personal protective equipment protocol (“PPE”) requirements for Smile Guides; reconfigured its production lines to observe social distancing; and implemented enhanced cleaning and sanitizing routines, thermal temperature screening, mandatory PPE protocols and other health and safety measures at its manufacturing facilities. The Company also enacted a resilience policy that provides its team members paid leave for COVID-19 testing and up to two weeks of paid leave for any required self-quarantine due to the team member testing positive for COVID-19.

Additionally, the Company took the following actions beginning in the second quarter of 2020 in an effort to fortify the financial position of the business: reduced its marketing spend as a percentage of revenue; reduced its headquarters and retail workforce; secured long-term financing; and initiated a real estate repositioning program.

Beginning in the second quarter of 2020, the Company performed a review of its real estate needs and initiated restructuring actions related to a real estate repositioning program that remains ongoing. As a result of these actions, the Company incurred one-time charges of approximately $32,491 during the year ended December 31, 2020. This one-time charge was primarily associated with the closure of our manufacturing facility in Kyle, Texas; the consolidation of several floors at our headquarters in Nashville, Tennessee; the closure and consolidation of many of our SmileShops, which is an on-going evaluation; and the impairment of right of use assets and leasehold improvements at the closed SmileShops. During the year ended December 31, 2021, the Company incurred one-time charges of approximately $5,279, primarily associated with store closure costs and further consolidation of corporate office space. Given the uncertain operating environment and the shift to work-from-home, the Company made the strategic decision to align its rent costs with the current needs of the business, while also ensuring that the Company has sufficient capacity to support future growth. The Company continues to evaluate its properties to determine if it will further rationalize its footprint to better align with marketplace demand, including the direct and indirect effects of the COVID-19 pandemic.

Summary of Significant Accounting Policies

Management Use of Estimates

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that impact the reported amounts. On an ongoing basis, the Company evaluates its estimates, including those related to the fair values of financial instruments, useful lives of property, plant and equipment, revenue recognition, equity-based compensation, long-lived assets, and contingent liabilities, among others. In connection with its credit facility with HPS Investment Partners, the Company issued warrants to certain affiliates of HPS Investment Partners. The warrants were recorded at fair value at the time of issuance within equity on the consolidated balance sheet using the Black-Scholes option pricing model (see Note 10). Each of these estimates varies in regard to the level of judgment involved and its potential impact on the Company’s financial results. Estimates are considered critical either when a different estimate could have reasonably been used, or where changes in the estimate are reasonably likely to occur from period to period, and such use or change would materially impact the Company’s financial condition, results of operations, or cash flows. Actual results could differ from those estimates.

Revenue Recognition

The Company’s revenues are derived primarily from sales of aligners, impression kits, whitening gel, and retainers, and interest earned through its SmilePay financing program. Revenue is recorded for all customers based on the amount that is expected to be collected, which considers implicit price concessions, discounts, and cancellations and refunds from customer returns.

The Company 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 (“SSP”) and allocation of consideration from a 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, usage rates (the number of times a customer is expected to order additional aligners), costs, and expected margin, which may vary over time depending upon the unique facts and circumstances related to each performance obligation, in making these estimates. Further, the Company’s process for estimating usage rates requires significant judgment and evaluation of inputs, including historical data and forecasted usages. Changes in the allocation of the SSP between performance obligations will not affect the amount of total revenues recognized for a particular contract. The Company uses the expected cost plus a margin approach to determine the SSP for performance obligations, and discounts are allocated to each performance obligation based on the relative SSP. However, any material changes in the allocation of the SSP could impact the timing of revenue recognition, which may have a material effect on the Company’s financial position and result of operations as 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.

The Company estimates the amount expected to be collected based upon management’s assessment of historical write-offs, expected net collections including implicit price concessions, and cancellations and refunds from customer returns, business and economic conditions, and other collection indicators. Management relies on the results of detailed reviews of historical write-offs, cancellations, returns, and collections as a primary source of information in estimating the amount of contract consideration expected to be collected. Uncollectible receivables are written-off in the period management believes it has exhausted its ability to collect payment from the customer. The Company believes its analysis provides reasonable estimates of its revenues and valuations of its accounts receivable.

A description of the revenue recognition for each product sold by the Company is detailed below.

Aligners and Impression Kits: The Company enters into contracts with customers for aligner sales that involve multiple future performance obligations. The Company determined that aligner sales comprise the following distinct performance

obligations: initial aligners, touch-up aligners, and retainers for international sales only which can occur at any time throughout the treatment plan (which is typically between five months to ten months) upon the direction of and prescription from the treating dentist or orthodontist.

The Company allocates revenues for each performance obligation based on its SSP and recognizes the revenues as control of the performance obligation is transferred upon shipment of the aligners. The Company recognizes aligner revenue on amounts expected to be collected during the course of the treatment plan.

The Company bills its customers either upfront for the full cost of aligners or monthly through its SmilePay financing program, which involves a down payment and a fixed amount per month for up to 24 months. The Company’s accounts receivable related to the SmilePay financing program are reported at the amount expected to be collected on the consolidated balance sheets, which considers implicit price concessions. Financing revenue from its accounts receivable is recognized based on the contractual market interest rate with the customer, net of implicit price concessions. There are no fees or origination costs included in accounts receivable.

The Company sells doctor-prescribed impression kits to its customers as an alternative to an in-person visit at one of its SmileShops, popup locations, or Partner Network locations, comprised of affiliated dentist and orthodontist offices, where the customer receives a free oral digital imaging of their teeth. The Company combines the sales of its impression kits with aligner sales and recognizes the revenues as control of the performance obligation is transferred upon shipment of the aligners. The Company estimates the amount of impression kit sales that do not result in an aligner therapy treatment plan and recognizes such revenue when aligner conversion becomes remote.

Retainers and Other Products: The Company sells retainers and other products (such as whitening gel and tooth brushes) to customers, which can be purchased on the Company’s website or certain retail outlets. The sales of these products are independent and separate from the customer’s decision to purchase aligner therapy for domestic sales. The Company determined that the transfer of control for these performance obligations occurs as the title of such products passes to the customer or retail partner.

The following table summarizes revenue recognized for each product sold by the Company:

	Years Ended December 31,
	2021		2020		2019
Aligner revenue, net	$	517,552	$	543,136	$	683,429
Financing revenue, net	42,919		49,407		43,899
Retainers and other products revenue	77,140		64,237		23,100
Total revenue	$	637,611	$	656,780	$	750,428
Implicit price concessions, cancellations, and refunds included in total revenue	$	129,307	$	138,841	$	125,535

Deferred Revenue: Deferred revenue represents the Company’s contract liability for performance obligations associated with sales of aligners. During the years ended December 31, 2021, 2020, and 2019, the Company recognized $637,611, $656,780, and $750,428 of revenue, respectively, of which $22,550, $19,750 and $16,630 was previously included in deferred revenue on the consolidated balance sheets as of December 31, 2020, 2019 and 2018, respectively.

Allowance for credit losses and other revenue adjustments: The Company records a provision to maintain an allowance for credit losses and other revenue adjustments that result from the failure or inability of its members or other partners to make required payments deemed collectible when the product was delivered, or customer returns resulting in cancellations or refunds. When determining the allowances for member receivables, the Company considers the probability of recoverability of accounts receivable based on past experience, taking into account current collection trends and general economic factors, including bankruptcy rates. The Company also considers future economic trends in its estimation of expected credit losses over the lifetime of the asset. Credit risks are assessed based on historical write-offs, cancellations, and adjustments, net of

recoveries, as well as an analysis of the aged accounts receivable balances. Accounts receivable may be fully reserved for when specific collection issues are known to exist, such as a history of missed scheduled payments and customer service or production issues.

Activity in the allowance for credit losses and other revenue adjustments for the year ended December 31, 2021 was as follows:

Balance at December 31, 2020	$	53,740
Current period provision for expected credit losses and other revenue adjustments	129,307
Write-offs and other adjustments charged against the allowance, net of recoveries	(116,031)
Refunds paid	(17,707)
Balance at December 31, 2021	$	49,309

As of December 31, 2021 and 2020, approximately $43,097 and $49,264 related to implicit price concessions and cancellation and adjustment reserves and is included in net receivables, respectively, and $6,212 and $4,476 related to refund reserves and is included in current liabilities in the accompanying consolidated balance sheets, respectively.

Shipping and Handling Costs

Shipping and handling charges are recorded in cost of revenues in the consolidated statements of operations upon shipment. The Company incurred approximately $22,892, $23,036 and $19,000 in outsourced shipping expenses for the years ended December 31, 2021, 2020 and 2019, respectively.

Cost of Revenues

Cost of revenues includes the total cost of products produced and sold. Such costs include direct materials, direct labor, overhead costs (occupancy costs, indirect labor, and depreciation), fees retained by doctors, freight and duty expenses associated with moving materials from vendors to the Company’s facilities and from its facilities to the customers, and adjustments for shrinkage (physical inventory losses), lower of cost or net realizable value, slow moving product and excess inventory quantities.

Marketing and Selling Expenses

Marketing and selling expenses include direct online and offline marketing and advertising costs, costs associated with intraoral imaging services, selling labor, and occupancy costs of SmileShop locations. All marketing and selling expenses, including advertising, are expensed as incurred. For the years ended December 31, 2021, 2020 and 2019, the Company incurred marketing, selling, and advertising costs of $388,450, $322,919 and $481,468, respectively.

General and Administrative Expenses

General and administrative expenses include payroll and benefit costs for corporate team members, equity-based compensation expenses, occupancy costs of corporate facilities, bank charges and costs associated with credit and debit card interchange fees, outside service fees, and other administrative costs, such as computer maintenance, supplies, travel, and lodging.

Depreciation and Amortization

Depreciation includes expenses related to the Company’s property, plant and equipment, including capital leases. Amortization includes expenses related to definite-lived intangible assets and capitalized software. Depreciation and amortization is calculated using the straight-line method over the useful lives of the related assets, ranging from three to ten years. Leasehold improvements are amortized using the straight-line method over the shorter of the related lease terms or

their useful lives. Depreciation and amortization is included in cost of revenues, selling expenses, and general and administrative expenses depending on the purpose of the related asset.

Depreciation and amortization by financial statement line item were as follows:

	Years Ended December 31,
	2021		2020		2019
Cost of revenues	$	27,467	$	24,718	$	11,186
Marketing and selling expenses	5,001		7,079		5,322
General and administrative expenses	37,645		24,593		10,828
Total	$	70,113	$	56,390	$	27,336

Fair Value of Financial Instruments

The Company measures the fair value of financial instruments 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. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

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.

Level 3 — Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability.

The Company’s financial instruments consist of cash, current and non-current receivables, accounts payable, debt instruments, and derivative financial instruments. Due to their short-term nature, the carrying values of cash, current receivables, and trade payables approximate current fair value at each balance sheet date. The Company had $747,500 and $407,902 in borrowings under its debt facilities (as discussed in Note 10) as of December 31, 2021 and 2020, respectively. The fair value of the Company’s debt facilities is based upon market quotes and trades by investors in partial interests of these instruments (Level 2). As of December 31, 2021 the fair value of the debt facility was approximately $305,167 compared to its carrying value of $729,973.

Derivative Financial Instruments

The Company accounts for derivative financial instruments in accordance with applicable accounting standards for such instruments and hedging activities, which require that all derivatives are recorded on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability. The Company had no outstanding derivatives at December 31, 2021

or 2020; however, the Company may enter into derivative contracts that are intended to economically hedge a certain portion of its risk, even though hedge accounting does not apply or the Company elects not to apply the hedge accounting standards.

Certain Risks and Uncertainties

The Company’s operating results depend to a significant extent on the ability to market and develop its products. The life cycles of the Company’s products are difficult to estimate due, in part, to the effect of future product enhancements and competition. The inability to successfully develop and market the Company’s products as a result of competition or other factors would have a material adverse effect on its business, financial condition, and results of operations.

The Company provides credit to customers in the normal course of business. The Company maintains reserves for potential credit losses and such losses have been within management’s expectations. No individual customer accounted for 1% or more of the Company’s accounts receivable at December 31, 2021 or 2020, or net revenue for the years ended December 31, 2021, 2020 and 2019.

Some of the Company’s products are considered medical devices and are subject to extensive regulation in the U.S. and internationally. The regulations to which the Company is subject are complex. Regulatory changes could result in restrictions on the Company’s ability to carry on or expand its operations, higher than anticipated costs or lower than anticipated sales. The failure to comply with applicable regulatory requirements may have a material adverse impact on the Company.

The Company’s reliance on international operations exposes it to related risks and uncertainties, including difficulties in staffing and managing international operations, such as hiring and retaining qualified personnel; 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, operating results may be harmed.

The Company purchases certain inventory from sole suppliers, and the inability of any supplier or manufacturer to fulfill the supply requirements could materially and adversely impact its future operating results.

Cash

Cash consists of all highly liquid investments with original maturities of less than three months. Cash is held in various financial institutions in the U.S. and internationally.

Inventories

Inventories are stated at the lower of cost or net realizable value using the first-in, first-out method of inventory accounting. Inventory consists of raw materials for producing impression kits and aligners and finished goods. Inventory is net of shrinkage and obsolescence.

Property, Plant and Equipment, Net

Property, plant and equipment are stated at cost less accumulated depreciation and amortization. Routine maintenance and repairs are charged to expense as incurred. At the time property, plant and equipment are retired from service, the cost and accumulated depreciation or amortization are removed from the respective accounts and the related gains or losses are reflected in the consolidated statements of operations.

Leases

On January 1, 2020, the Company adopted the new leases standard using the modified retrospective transition method, which requires that it recognizes leases differently pre- and post-adoption. The Company categorizes leases at their inception

as either operating or finance leases. Lease agreements cover certain retail locations, office space, warehouse, manufacturing and distribution space and equipment. Operating leases are included in operating lease right-of-use assets, other current liabilities, and long-term right-of-use operating lease obligations in the consolidated balance sheets. Finance leases are included in property, plant and equipment, net, current portion of long-term debt, and long-term debt.

Leased assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The Company uses a secured incremental borrowing rate as the discount rate for determining the present value of lease payments when the rate implicit in the contract is not readily determinable. Leases that have a term of twelve months or less upon commencement date are considered short-term in nature. Accordingly, short-term leases are not included on the consolidated balance sheets and are expensed on a straight-line basis over the lease term, which commences on the date we have the right to control the property.

Internally Developed Software Costs

The Company generally provides services to its customers using software developed for internal use. The costs that are incurred to develop such software are expensed as incurred during the preliminary project stage. Once certain criteria have been met, direct costs incurred in developing or obtaining computer software are capitalized. Training and maintenance costs are expensed as incurred. Capitalized software costs are included in property, plant and equipment in the consolidated balance sheets and are amortized over useful life of the software which is generally a three-year to five-year period. During the years ended December 31, 2021, 2020, and 2019, the Company capitalized $58,558, $21,509 and $11,861, respectively, of internally developed software costs. Amortization expense for internally developed software was $17,973, $7,978 and $3,384 for the years ended December 31, 2021, 2020, and 2019, respectively.

Impairment

The Company evaluates long-lived 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 generate. Factors the Company considers 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. The Company’s estimates of future cash flows attributable to long-lived assets require significant judgment based on its 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 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.

Debt Issuance Costs

The Company records debt issuance costs related to its term debt as direct deductions from the carrying amount of the debt. The costs are amortized to interest expense over the life of the debt using the effective interest method.

Income Taxes

SDC Inc. is the managing member of SDC Financial and, as a result, consolidates the financial results of SDC Financial in the consolidated financial statements. SDC Financial and its subsidiaries are limited liability companies and have elected to be taxed as partnerships for income tax purposes except for a subsidiary, SDC Holding, LLC (‘‘SDC Holding”) and its domestic and foreign subsidiaries, which are taxed as corporations. As such, SDC Financial does not pay any federal income taxes, as any income or loss is included in the tax returns of the individual members. SDC Financial does pay state income

tax in certain jurisdictions, and the Company’s income tax provision in the consolidated financial statements reflects the income taxes for those states. Additionally, certain wholly-owned entities taxed as corporations are subject to federal, state, and foreign income taxes, in the jurisdictions in which they operate, and accruals for such taxes are included in the consolidated financial statements. The Company further evaluates deferred tax assets in each jurisdiction and recognizes associated benefits when positive evidence of realization exceeds negative evidence, and otherwise records valuation allowances as necessary.

The Company computes the provision for income taxes using the liability method and recognizes deferred tax assets and liabilities for temporary differences between financial statement and income tax bases of assets and liabilities, as well as for operating loss and tax credit carryforwards. The Company measures deferred tax assets and liabilities using tax rates applicable to taxable income in effect for the years in which those tax assets are expected to be realized or settled and provides a valuation allowance against deferred tax assets when it cannot conclude that it is more likely than not that some or all deferred tax assets will be realized. In addition, the Company recognizes tax benefits from uncertain tax positions only if it expects that its tax positions are more likely than not that they will be sustained, based on the technical merits of the positions, on examination by the jurisdictional tax authority. The Company recognizes any accrued interest and penalties to unrecognized tax benefits as interest expense and income tax expense, respectively.

Tax Receivable Agreement

In connection with the Reorganization Transactions and the IPO, the Company entered into a Tax Receivable Agreement with the Continuing LLC Members, pursuant to which SDC Inc. agreed to pay the Continuing LLC Members 85% of the amount of cash tax savings, if any, in U.S. federal, state, and local income tax or franchise tax that SDC Inc. actually realizes as a result of (a) the increases in tax basis attributable to exchanges by Continuing LLC Members and (b) tax benefits related to imputed interest deemed to be paid by SDC Inc. as a result of the Tax Receivable Agreement. The Company recognizes this contingent liability in its consolidated financial statements when amounts become probable as to incurrence and estimable in amount.

Recently Adopted Accounting Pronouncements

In January 2021 the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standard Update (“ASU”) 2016-13, “Financial Instruments—Credit Losses” (Topic 326). The FASB issued this update 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 adoption of this standard did not have a material impact on the Company’s consolidated financial statements and related disclosures.

In January 2021, the Company adopted FASB ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." This standard simplified the accounting for income taxes by eliminating certain exceptions to the guidance in Topic 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an period and the recognition of deferred tax liabilities for outside basis differences. The guidance also simplified aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill and allocating consolidated income taxes to separate financial statements of entities not subject to income tax. The Company adopted the provisions of this guidance effective January 1, 2021 using the modified retrospective method of adoption which required no cumulative-effect adjustment to retained earnings as of the beginning of the period.

In January 2021, the Company adopted FASB ASU 2020-06, “Accounting for Convertible Instruments and Contracts in an Entity's Own Equity,” which eliminates most of the guidance in Subtopic 470-20 that requires separate accounting for embedded conversion features in convertible debt arrangements. Further, ASU 220-06 removes some of the conditions in

Subtopic 815-40-25, “Contracts on an Entity's own Equity,” that are required for equity classification, including the requirement for equity contracts to permit settlement in unregistered shares. The Company adopted the provisions of this guidance effective January 1, 2021, using the modified retrospective method of adoption which required no cumulative-effect adjustment to retained earnings as of the beginning of the period. The Company applied the provisions of this guidance to the recently issued 2026 Convertible Senior Notes and related capped call transactions.

Restructuring and Related Activities [Abstract]

Lease Abandonment, Impairment of Long-Lived Assets and Store Closure and Other Related Charges

Lease Abandonment, Impairment of Long-lived Assets and Store Closure and Other Related ChargesThe Company evaluates its real estate needs on a recurring basis and beginning in the second quarter of 2020, initiated restructuring actions related to a real estate repositioning program. As a result of these changes, the Company incurred one-time charges of $5,279 for the year ended December 31, 2021. These charges were primarily associated with store closure costs and consolidation of a portion of SmileShops, which is an on-going evaluation. Given the uncertain operating environment and the shift to work-from-home, the Company made the strategic decision to align its rent costs with the current needs of the business, while also ensuring that the Company has sufficient capacity to support future growth. The Company continues to evaluate its SmileShops and other properties to determine if it will further rationalize its footprint to

better align with marketplace demand, including the direct and indirect effects of the COVID-19 pandemic. Additional future restructuring charges may result from the Company’s real estate repositioning and optimization initiatives.

The following table summarizes restructuring charges for the periods presented:

Leases [Abstract]

Leases

LeasesThe Company leases property and equipment under finance and operating leases. For leases with terms greater than 12 months, the Company records the related right-of-use assets and right-of-use obligations at the present value of lease payments over the term. Certain of the Company’s leases include rental escalation clauses and renewal options that are factored into the determination of lease payments when appropriate. Certain of the Company’s leased store locations have variable payments based upon scan volume as well as other variable property related costs. The Company does not separate lease and non-lease components of contracts.

Generally, the Company uses its estimated incremental borrowing rate to discount the lease payments based on information available at lease commencement, as most of its leases do not provide a readily determinable implicit interest rate. The Company estimates its collateralized incremental borrowing rate based upon a synthetic credit rating and yield curve analysis at commencement or modification date in determining the present value of lease payments.

Income Tax Disclosure [Abstract]

Income Taxes

Income TaxesSDC Inc. is the managing member of SDC Financial and, as a result, consolidates the financial results of SDC Financial. SDC Financial and its subsidiaries are limited liability companies and have elected to be taxed as partnerships for income tax purposes, except for a subsidiary, SDC Holding and certain of its domestic and foreign subsidiaries, are taxed as corporations. The Company files income tax returns in the U.S. federal, various states and foreign jurisdictions. Any taxable income or loss

generated by SDC Financial is passed through to and included in the taxable income or loss of its members, including SDC Inc., generally on a pro rata basis or otherwise under the terms of the SDC Financial LLC Agreement. The Company is subject to U.S. federal income taxes, in addition to state and local income taxes with respect to its allocable share of any taxable income or loss of SDC Financial, as well as any stand-alone income or loss generated by SDC Inc.

The Company’s U.S. federal and state income tax returns for the tax years 2017 and beyond remain subject to examination by the Internal Revenue Service. The Company also has operations in Costa Rica, Puerto Rico, Canada, Mexico, Australia, the U.K., Germany, Austria, the Netherlands, Spain, Ireland, France, Hong Kong, Singapore, Taiwan, and New Zealand with tax filings in each foreign jurisdiction. With respect to state and local jurisdictions, the Company and its subsidiaries are typically subject to examination for several years after the income tax returns have been filed. Although the outcome of tax audits is always uncertain, the Company believes that adequate amounts of tax, interest and penalties have been provided for in the accompanying consolidated financial statements for any adjustments that may be incurred due to state or local audits and uncertain tax positions. The Company is also subject to withholding taxes in foreign jurisdictions. The Company’s income tax expense may vary from the expense that would be expected based on statutory rates due principally to its organizational structure and recognition of valuation allowances against deferred tax assets.

Deferred Tax Assets and Liabilities

Deferred income taxes reflect the net tax effects of tax carryovers and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the balances for income tax purposes. Significant components of deferred tax assets and liabilities are as follows:

	Years Ended December 31,
	2021		2020
Deferred tax assets:
Deferred revenue	$	369	$	351
Accruals and reserves	4,411		3,511

Deferred warrant expense	—		—

Other	(757)		—
Gross deferred tax liabilities	(1,571)		(818)
Net deferred tax liabilities	$	(792)	$	(161)

At December 31, 2021 the Company had unused federal net operating loss carryforwards (tax effected) for federal income tax purposes of approximately $71,464, which can be carried forward indefinitely and may be used to offset future taxable income. In addition, the Company had unused net operating loss carryforwards (tax effected) for state income tax purposes of approximately $33,434, which expire from 2029 through 2035. The Company also had unused net operating loss carryforwards (tax effected) for foreign income tax purposes of approximately $6,515. Additionally, the Company has certain other deferred tax assets related to potential future tax benefits. All deferred tax assets are evaluated using positive and negative evidence as to their future realization. The Company considers recent historic losses to be significant negative evidence, and as such, records a valuation allowance against substantially all of its deferred tax assets.As of December 31, 2021, the Company maintained a valuation allowance of approximately $288,506 against its deferred tax assets. If there is a change in the Company’s assessment of the amount of deferred income tax assets that is realizable, adjustments to the valuation allowance will be made in future periods.

Unrecognized Tax Benefits

A reconciliation of the Company’s gross unrecognized tax benefits is as follows:

	Years Ended December 31,
	2021		2020
Balance at beginning of year	$	2,555	$	1,006
Increases for tax positions taken in prior years	—		462
Decreases for tax positions taken in prior years	—		—
Increases for tax positions taken in current year	438		1,087
Decreases for settlements with taxing authorities	—		—
Decreases for lapsing of the statute of limitations	(65)		—
Balance at end of year	$	2,928	$	2,555

The total amount of accrued interest and penalties were not significant as of December 31, 2021. The total amount of unrecognized tax benefit recorded during 2021 and 2020 was $2,928 and $2,555, respectively. All our unrecognized tax benefits, if recognized, would have a favorable impact on the effective tax rate.

Tax Receivable Agreement

The Company expects to obtain an increase in its share of the tax basis in the net assets of SDC Financial when LLC Units are redeemed from or exchanged by Continuing LLC Members. The Company intends to treat any redemptions and exchanges of LLC Units as direct purchases of LLC Units for U.S. federal income tax purposes. These increases in tax basis may reduce the amounts that it would otherwise pay in the future to various tax authorities. They may also decrease gains (or increase losses) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets.

In connection with the Reorganization Transactions and the IPO, the Company entered into the Tax Receivable Agreement with the Continuing LLC Members. The Tax Receivable Agreement provides for the payment by SDC Inc. of 85% of the amount of any tax benefits that SDC Inc. actually realizes, or in some cases is deemed to realize, as a result of (i) increases in SDC Inc.’s share of the tax basis in the net assets of SDC Financial resulting from any redemptions or exchanges of LLC Units, (ii) tax basis increases attributable to payments made under the Tax Receivable Agreement, and (iii) deductions attributable to imputed interest pursuant to the Tax Receivable Agreement (collectively, the “TRA Payments”). The Company expects to benefit from the remaining 15% of any of cash savings, if any, that it realizes.

During the year ended December 31, 2019, the Company acquired an aggregate of $635,690 in LLC Units in connection with the redemption of certain Continuing LLC Members, which resulted in an increase in the tax basis of the assets of SDC Financial subject to the provisions of the Tax Receivable Agreement. The Company has not recognized any additional liability under the Tax Receivable Agreement after concluding it was not probable that such TRA Payments would be paid based on its estimates of future taxable income. No payments were made to the Continuing LLC Members pursuant to the Tax Receivable Agreement during the years ended December 31, 2021 or 2020.

The amounts payable under the Tax Receivable Agreement will vary depending upon a number of factors, including the amount, character, and timing of the taxable income of SDC Inc. in the future. If the valuation allowance recorded against the deferred tax assets applicable to the tax attributes referenced above is released in a future period, the Tax Receivable Agreement liability may be considered probable at that time and recorded within earnings.

2026 Convertible Senior Notes

On February 9, 2021, the Company issued $650,000 principal amount of the Company’s 0.00% Convertible Senior Notes due 2026 (the “Notes”). The Company also granted the initial purchasers of the Notes an option to purchase up to an additional $97,500 aggregate principal amount of the Notes (“Option Notes”). On February 9, 2021, the initial purchasers of the Notes exercised their option to purchase $70,000 aggregate principal amount of the Option Notes (the “First Greenshoe Exercise”). The sale of the Option Notes from the First Greenshoe Exercise closed on February 12, 2021. On February 11, 2021, the initial purchasers of the Notes exercised the remaining portion of their option to purchase $27,500 aggregate principal amount of the Option Notes (the “Second Greenshoe Exercise” and, the Option Notes issued in connection with the Second Greenshoe Exercise, the “Second Greenshoe Option Notes”). The sale of the Second Greenshoe Option Notes closed on February 16, 2021.

The Notes were issued and governed by an indenture, dated February 9, 2021, (the “Indenture”), between the Company and Wilmington Trust, National Association, as trustee. The Notes will mature on February 1, 2026, unless earlier repurchased, redeemed or converted. The Notes will not bear regular interest, and the principal amount of the Notes will not accrete.

The initial conversion rate for the Notes is 55.3710 shares of the Company's Class A Common Stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $18.06 per share of Class A Common Stock. The initial conversion price of the Notes represents a premium of approximately 40% over the last reported sale of $12.90 per share of the Company's Class A Common Stock on February 4, 2021. The conversion rate and conversion price will be subject to customary adjustments upon the occurrence of certain events in accordance with the terms of the Indenture.

The Company recorded $21,338 related to deferred financing costs of the Notes. During the year ended December 31, 2021, the Company amortized under the effective interest rate method $3,811 of deferred financing costs.

The Notes are the Company’s senior, unsecured obligations and are (i) equal in right of payment with the Company’s existing and future senior, unsecured indebtedness; (ii) senior in right of payment to the Company’s existing and future indebtedness that is expressly subordinated to the Notes; (iii) effectively subordinated to the Company’s existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness; and (iv) structurally subordinated to all existing and future indebtedness and other liabilities, including the Company’s trade payables, and (to the extent the Company is not a holder thereof) preferred equity, if any, of the Company’s subsidiaries.

The Company may, at its option, redeem some of the Notes, in whole or in part, at the applicable redemption price as set forth in the Indenture.

If certain corporate events that constitute a “Fundamental Change” (as defined in the Indenture) occur, then, noteholders may require the Company to repurchase their Notes at a cash repurchase price equal to the principal amount of the Notes to be repurchased, plus accrued and unpaid special interest, if any. The definition of Fundamental Change includes certain business combination transactions involving the Company and certain de-listing events with respect to the Company’s Class A common stock.

The Notes have customary provisions relating to the occurrence of an “Event of Default” (as defined in the Indenture), which include the following: (i) a default by the Company in the payment when due (whether at maturity, upon redemption or repurchase upon fundamental change or otherwise) of the principal of, or the redemption price or fundamental change repurchase price for, any Note (ii) a default by the Company for 30 days in the payment when due of special interest, if any, on any Note; (iii) the Company’s failure to send certain notices under the Indenture within specified periods of time; (iv) a default by the Company in its obligation to convert a Note in accordance with the Indenture upon the exercise of the conversion right with respect thereto, if such default is not cured within three business days after its occurrence; (v) the Company’s failure to comply with certain covenants in the Indenture relating to the Company’s ability to consolidate with or merge with or into, or sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Company and its subsidiaries, taken as a whole, to another person; (vi) a default by the Company in its other obligations or agreements under the Indenture or the Notes (other than a default set forth in clauses (i), (ii), (iii), (iv) or (v) above) if such default is not cured or waived within 60 days after written notice is given in accordance with the Indenture; (vii) certain defaults by the Company or any of its significant subsidiaries with respect to indebtedness for borrowed money of at least $50,000; and (viii) certain events of bankruptcy, insolvency and reorganization involving the Company or any of the Company’s significant subsidiaries.

If an Event of Default involving bankruptcy, insolvency or reorganization events with respect to the Company (and not solely with respect to a significant subsidiary of the Company) occurs, then the principal amount of, and all accrued and unpaid special interest, if any, on, all of the Notes then outstanding will immediately become due and payable without any further action or notice by any person. If any other Event of Default occurs and is continuing, then, the Trustee, by notice to the Company, or noteholders of at least 25% of the aggregate principal amount of Notes then outstanding, by written notice to the Company and the Trustee, may declare the principal amount of, and all accrued and unpaid special interest, if any, on, all of the Notes then outstanding to become due and payable immediately. However, notwithstanding the foregoing, the Company may elect, at its option, that the sole remedy for an Event of Default relating to certain failures by the Company to comply with certain reporting covenants in the Indenture consists exclusively of the right of the noteholders to receive special interest on the Notes for up to 180 days at a specified rate per annum not exceeding 0.50% on the principal amount of the Notes.

The Company used approximately $69,518 of the net proceeds from the Notes to fund the cost of entering into the capped call transactions described below. The Company used a portion of the remainder of the net proceeds from the offering to repay amounts owed under the HPS Credit Facility.

On February 4, 2021, in connection with the pricing of the Notes, the Company entered into privately negotiated capped call transactions (the “Base Capped Call Transactions”) with certain of the initial purchasers of the Notes and/or their respective affiliates and/or other financial institutions (the “Option Counterparties”). In addition, on February 9, 2021, in connection with First Greenshoe Exercise and on February 11, 2021, in connection with the Second Greenshoe Exercise, the Company entered into additional privately negotiated capped call transactions (collectively, and together with the Base Capped Call Transactions, the “Capped Call Transactions”) with the Option Counterparties. The Capped Call Transactions cover, subject to anti-dilution adjustments substantially similar to those applicable to the Notes, the number of shares of Class A common stock initially underlying the Notes. The Capped Call Transactions are expected generally to reduce potential dilution to the Class A common stock upon any conversion of the Notes and/or offset any potential cash payments the Company is required to make in excess of the principal amount of such converted Notes, as the case may be, with such reduction and/or offset subject to a cap.

The Capped Call Transactions are separate transactions entered into by the Company with each Option Counterparty, and are not part of the terms of the Notes and will not affect any noteholder’s rights under the Notes. Noteholders will not have any rights with respect to the Capped Call Transactions.

In connection with the issuance of the Notes, SmileDirectClub, Inc. entered into an intercompany convertible promissory note (“Intercompany Convertible Note”) with SDC Financial, LLC, whereby SmileDirectClub, Inc. provided the net proceeds from the issuance of the Notes to SDC Financial, LLC. The terms of the Intercompany Convertible Note mirrors the terms of the Notes issued by SmileDirectClub, Inc. The intent of the Intercompany Convertible Note is to maintain the parity of shares of Class A common stock with LLC Units as required by the SDC Financial LLC Agreement.

HPS Credit Facility

In May 2020, SDC U.S. SmilePay SPV (“SPV”), a wholly-owned special purpose subsidiary of the Company, entered into a Loan Agreement among SPV, as borrower, SmileDirectClub, LLC, as the seller and servicer, certain lenders, and HPS Investment Partners, LLC, as administrative agent and collateral agent, providing a five-year secured term loan facility to SPV in an initial aggregate maximum principal amount of $400,000, net of original issue discount of $12,000, with the ability to request incremental term loans of up to an additional aggregate principal amount of $100,000 with the consent of the lenders participating in such increase (the “HPS Credit Facility”).

The proceeds of the HPS Credit Facility were used to repay all outstanding amounts under the previous JPM Credit Facility and for working capital and other corporate purposes. In connection with the repayment, the Company paid $187 in fees and wrote-off the remaining unamortized loan costs of $1,594, both of which were included in loss from extinguishment of debt in the period in which the HPS Credit Facility was entered.

The Company recorded $11,784 related to deferred financing costs of the HPS Credit Facility in the second quarter of 2020. During the year ended December 31, 2021, the Company amortized under the effective interest rate method $536 of deferred financing costs. The remaining original issue discount is included in loss from extinguishment of debt in the accompanying consolidated statements of operations for the year ended December 31, 2021.

Outstanding loans under the HPS Credit Facility bore interest at a variable rate equal to three-month LIBOR (subject to a 1.75% per annum floor), plus 7.50% per annum payable in cash, plus 3.25% per annum payable in kind or, at the Company’s election, wholly or partially in cash.

Subject to certain exceptions, the HPS Credit Facility was secured by first-priority security interests in SPV’s assets, which consisted of certain receivables, cash governed by a control agreement with HPS, intellectual property and related assets. SPV’s obligations under the Loan Agreement were guaranteed on a limited basis by SmileDirectClub, LLC and SDC Financial LLC.

The HPS Credit Facility contained various restrictions, covenants, ratios and events of default, including:

•SPV had limitations on consolidations, creation of liens, incurring additional indebtedness, dispositions of assets, investments and paying dividends or other distributions.

•SDC Financial LLC, its consolidated subsidiaries and certain originator entities had to maintain minimum monthly liquidity of $100,000 and are subject to additional leverage ratios upon the occurrence of additional debt.

•SDC Financial LLC was subject to a consolidated leverage ratio measured as of the end of each fiscal quarter beginning March 31, 2022, to be calculated based on annualized EBITDA for the first three quarters of 2022, and thereafter, to be calculated based on EBITDA during the trailing four fiscal quarters for the relevant period.

The HPS Credit Facility could have been refinanced during the first year, provided that SPV would be required to pay the amount of interest that would have accrued during the remainder of the first year, plus 4% of the principal amount prepaid; and after the first year, for a fee of 4% of the principal amount prepaid, with the prepayment fee decreasing each year to 3% in the third year, 2% in the fourth year and 1% in the fifth year.

On March 29, 2021, the HPS Credit Facility was paid in full and terminated. In connection with the repayment, the unamortized loan costs, the unaccreted warrant value, and the prepayment fee described above are recorded as a loss on extinguishment of debt in the accompanying consolidated statements of operations.

HPS Warrants

In connection with the HPS Credit Facility, the Company issued warrants (“HPS Warrants”) to affiliates of HPS Investment Partners, LLC exercisable at any time into an aggregate of 3,889,575 shares of the Company’s Class A common stock, which amounted to 1% of the Company’s total outstanding Class A and Class B common stock, including the HPS Warrants, as of the closing date of the HPS Credit Facility, at an exercise price of $7.11 per share, payable in cash or pursuant to a cashless exercise. The HPS Warrants were recorded at their initial fair value of $17,620 and included within stockholders’ equity. The termination and payoff of the HPS Credit Facility did not impact the HPS Warrants.

Align Redemption Promissory Note

In connection with the required redemption of Align’s 20,710 Pre-IPO Units described in Note 16, the Company entered into a promissory note with Align Technology, Inc. (“Align”). Under the terms of the promissory note, the Company was scheduled to make monthly payments of $2,311 to Align through March 2021. The promissory note bore annual interest of 2.52% which is included in the consolidated statement of operations. As of December 31, 2021, the Company has $0 outstanding under this promissory note.

Noncontrolling Interest [Abstract]
Noncontrolling Interests	Noncontrolling InterestsSDC Inc. is the sole managing member of SDC Financial, and consolidates the financial results of SDC Financial. Therefore, SDC Inc. reports a noncontrolling interest based on the common units of SDC Financial held by the Continuing LLC Members. Changes in SDC Inc.’s ownership interest in SDC Financial, while SDC Inc. retains its controlling interest in SDC Financial, are accounted for as equity transactions. As such, future redemptions or direct exchanges of LLC Units by the Continuing LLC Members will result in a change in ownership and reduce or increase the amount recorded as noncontrolling interest and increase or decrease additional paid-in capital when SDC Financial has positive or negative net assets, respectively. As of December 31, 2021, SDC Inc. had 119,280,781 shares of Class A common stock outstanding, which resulted in an equivalent amount of ownership of LLC Units by SDC Inc. As of December 31, 2021, SDC Inc. had a 30.7% economic ownership interest in SDC Financial.

Variable Interest Entities

Variable Interest Entities

Upon completion of the IPO, SDC Inc. became the managing member of SDC Financial with 100% of the management and voting power in SDC Financial. In its capacity as managing member, SDC Inc. has the sole authority to make decisions on behalf of SDC Financial and bind SDC Financial to signed agreements. Further, SDC Financial maintains separate capital accounts for its investors as a mechanism for tracking earnings and subsequent distribution rights. Accordingly, management concluded that SDC Financial is determined to be a limited partnership or similar legal entity as contemplated in ASC 810.

Furthermore, management concluded that SDC Inc. is SDC Financials’ primary beneficiary. As the primary beneficiary, SDC Inc. consolidates the results of SDC Financial for financial reporting purposes under the variable interest consolidation model guidance in ASC 810.

SDC Inc.’s relationship with SDC Financial results in no recourse to the general credit of SDC Inc. SDC Financial and its consolidated subsidiaries represents SDC Inc.’s sole investment. SDC Inc. shares in the income and losses of SDC Financial in direct proportion to SDC Inc.’s ownership percentage. Further, SDC Inc. has no contractual requirement to provide financial support to SDC Financial.

SDC Inc.’s financial position, performance and cash flows effectively represent those of SDC Financial as of and for the years ended December 31, 2021 and 2020. Prior to the IPO and Reorganization Transactions, SDC Inc. was not impacted by SDC Financial.

Share-based Payment Arrangement [Abstract]

Incentive Compensation Plans

Incentive Compensation Plans

In connection with the IPO, the Company adopted the 2019 Omnibus Incentive Compensation Plan (the “2019 Plan”) in August 2019. The Company’s board of directors or the compensation committee of the board of directors, acting as plan administrator, administers the 2019 Plan and the awards granted under it. The Company reserved a total of 38,486,295 shares of Class A common stock for issuance pursuant to the 2019 Plan. The Company currently has two types of share-based compensation awards outstanding under the 2019 Plan: Class A common stock options (“Options”) and Class A restricted stock units (“RSUs”), including those issued pursuant to IBAs.

Class A Common Stock Options

Options activity was as follows during the year ended December 31, 2021:

	Number of Options	Weighted Average Exercise Price		Weighted Average Remaining Contractual Term	Aggregate Intrinsic Value
Outstanding at December 31, 2020	1,679,339	$	23.00	8.7	$	—
Granted	50,000	12.21		9.1	—
Exercised	—	—		—	—
Expired	—	—		—	—
Forfeited	(65,217)	23.00		—	—
Outstanding at December 31, 2021	1,664,122	$	22.70	7.7	$	—
Exercisable at December 31, 2021	597,816	$	23.00	7.7	$	—

The Company estimates fair value of the Options using the Black-Scholes option pricing model. Inputs to the Black-Scholes option pricing model for awards issued during the years ended December 31, 2021, include an expected dividend

yield of 0.0%, expected volatility of 65.6%, risk-free interest rate of 0.8% and an expected term of 6.3 years, pursuant to time-based vesting terms, resulting in a weighted average fair value of $8.17 per Option. As of December 31, 2021, unrecognized compensation expense related to the Options was $4,183. This expense is expected to be recognized over a weighted average period of 0.9 years.

Expected dividend yield - An increase in the expected dividend yield would decrease compensation expense.

Expected volatility - This is a measure of the amount by which the price of the equity instrument has fluctuated or is expected to fluctuate. The expected volatility was based on the historical volatility of a group of guideline companies. An increase in expected volatility would increase compensation expense.

Risk-free interest rate - This is the U.S. Treasury rate as of the measurement date having a term approximating the expected life of the award. An increase in the risk-free interest rate would increase compensation expense.

Expected term - The period of time over which the awards are expected to remain outstanding. The Company estimates the expected term as the mid-point between actual or expected vesting date and the contractual term. An increase in the expected term would increase compensation expense.

Restricted Stock Units

Incentive Bonus Awards

The Company has IBA agreements with several key employees to provide a bonus payment in the event of a liquidation event as defined in each agreement. The bonus amounts are calculated based on the value of the Company at the time of the liquidation event, less an amount determined upon the employee entering into the agreement. The right to the payment generally vests annually over a five-year period, with certain liquidation events resulting in an acceleration of the vesting period. As the vesting of these awards was contingent on a liquidation event, no amounts were required to be recorded prior to a liquidation event. The IBA agreements were modified in August 2019 to accelerate certain vesting conditions upon a liquidation event and to modify the settlement terms, whereby the Company settled the vested portion of each IBA in 50% shares of Class A common stock and/or vested RSUs and 50% cash, of which approximately 80% of the cash (40% of the total vested portion of the award) that the IBA holders would have otherwise received was withheld by the Company to fulfill tax withholding obligations and the remainder was paid out to IBA holders upon the occurrence of a liquidation event. As a result of the modification and the occurrence of a liquidation event through the IPO, the Company recorded equity-based compensation expense of $316,959, equivalent to the amount of IBAs vested at the time of the IPO, in the form of cash, 5,654,078 shares of Class A common stock and 2,199,453 vested RSUs to be released over a period of six to twenty-four months following the date of the IPO. The unvested portion of the IBAs are represented in the form of unvested RSUs that will vest, subject to the holders’ continued employment, over a period generally ranging from 2 years to 4 years.

Non-IBA Restricted Stock Units

The Company granted RSUs to certain team members that generally vest annually over two to three years or after three years from the date of grant, subject to the recipient’s continued employment or service to the Company through each vesting date.

A summary of activity related to these RSUs is as follows:

	IBA RSUs	Non-IBA RSUs	Total RSUs	Weighted Average Grant Date Fair Value
RSUs outstanding, December 31, 2020	1,626,738	2,193,144	3,819,882	$	16.68
Granted	—	4,333,642	4,333,642	$	11.00

Forfeited	—	(555,538)	(555,538)	$	11.12
RSUs outstanding, December 31, 2021	156,088	4,681,073	4,837,161	$	15.53

As of December 31, 2021, unrecognized compensation expense related to unvested IBA and non-IBA RSUs was $38,812. This expense is expected to be recognized over a weighted average period of 2.4 years.

Employee Stock Purchase Plan

The SmileDirectClub, Inc. team member Stock Purchase Plan (“SPP”) was initiated in November 2019. Under the SPP, the Company is authorized to issue up to 5,772,944 shares of its Class A common stock to qualifying employees. Eligible team members may direct the Company, during each six months option period, to withhold up to 30% of their base salary and commissions, the proceeds from which are used to purchase shares of Class A common stock at a price equal to the lesser of 85% of the closing market price on the exercise date or the grant date. For accounting purposes, the SPP is considered a compensatory plan such that the Company recognizes equity-based compensation expense based on the fair value of the options held by the employees to purchase the Company’s shares.

Summary of Equity-Based Compensation Expense

The Company recognized compensation expense of $44,628, $44,903 and $350,122 for the years ended December 31, 2021, 2020 and 2019, respectively. Amounts are included in general and administrative expense on the consolidated statements of operations.

Earnings (Loss) Per Share

Earnings Per Share [Abstract]

Earnings (Loss) Per Share

Earnings (Loss) Per ShareBasic earnings per share of Class A common stock is computed by dividing net loss attributable to SDC Inc. by the weighted-average number of shares of Class A common stock outstanding during the period. Diluted earnings per share of Class A common stock is computed by dividing net loss attributable to SDC Inc., adjusted for the assumed exchange of all potentially dilutive LLC Units for Class A common stock, by the weighted-average number of shares of Class A common stock outstanding adjusted to give effect to potentially dilutive elements. Prior to the IPO, the SDC Financial membership structure included Pre-IPO Units, some of which were profits interests. The Company analyzed the calculation of earnings per unit for periods prior to the IPO and determined that it resulted in values that would not be meaningful to the users of these consolidated financial statements. Therefore, the basic and diluted earnings per share for the year ended December 31, 2019, represents only the period from September 11, 2019 to December 31, 2019, which represents the period wherein the Company had outstanding Class A common stock.

The following table sets forth reconciliations of the numerators and denominators used to compute basic and diluted earnings (loss) per share of Class A common stock:

Shares of the Company’s Class B common stock do not participate in the earnings or losses of the Company and are therefore not participating securities. As such, separate presentation of basic and diluted earnings (loss) per share of Class B common stock under the two-class method has not been presented.

Due to their anti-dilutive effect, the following securities have been excluded from diluted net earnings (loss) per share in the periods presented:

	Years Ended December 31,
	2021	2020	2019
Options	1,664,122	1,679,339	1,744,556

Shares issuable under the Notes (if converted method)(1)	41,389,822	—	—

(1) In connection with the issuance of the Notes, the Company entered into Capped Call Transactions, which were not included for purposes of calculating the number of diluted shares outstanding, as their effect would have been anti-dilutive. The Capped Call Transactions are expected to reduce the potential dilution to the Company’s common stock (or, in the event a conversion of the Notes is settled in cash, to reduce its cash payment obligation) in the event that at the time of conversion of the Notes the Company’s common stock price exceeds the conversion price of the Notes.

Legal Matters

In the ordinary course of conducting its business, the Company is involved, from time to time, in various contractual, product liability, intellectual property, and other claims and disputes incidental to its business. Litigation is subject to many uncertainties, the outcome of individual litigated matters is not predictable with assurance, and it is reasonably possible that some of these matters may be decided unfavorably to the Company and could have a material impact on the financial statements. In addition, the Company periodically receives communications from state and federal regulatory and similar agencies inquiring about the nature of its business activities, licensing of professionals providing services, and similar matters. Such matters are routinely concluded with no financial or operational impact on the Company.

From September to December 2019, a number of purported stockholder class action complaints were filed in the U.S. District Court for the Middle District of Tennessee and in state courts in Tennessee, Michigan, and New York against the Company, members of the Company’s board of directors, certain of its current or former officers, and the underwriters of its IPO.

SmileDirectClub, Inc., No. 652603/2020 (Supreme Ct. N.Y. Cty. filed June 19, 2020). The complaints all allege, among other things, that the registration statement filed with the SEC on August 16, 2019, and accompanying amendments, and the Prospectus filed with the SEC on September 13, 2019, in connection with the Company’s initial public offering were inaccurate and misleading, contained untrue statements of material facts, omitted to state other facts necessary to make the statements made not misleading, and omitted to state material facts required to be stated therein. The complaints seek unspecified money damages, other equitable relief, and attorneys’ fees and costs. All the actions are in the preliminary stages. The Company denies any alleged wrongdoing and is vigorously defending against these actions.

In December 2019, the Fernandez, Vang, Mancour and Wei Wei actions were consolidated and re-captioned In re SmileDirectClub, Inc. Securities Litigation, 19-1169-IV (Davidson County, TN Chancery Court). Plaintiffs filed a consolidated amended complaint on December 20, 2019, and Defendants moved to stay or dismiss the action on February 10, 2020. On June 4, 2020, the court denied that motion. Defendants subsequently moved for permission to seek an interlocutory appeal of that decision. On June 22, 2020, the court granted that motion. On August 3, 2020, Defendants filed an application for interlocutory appeal with the court of appeals, which was denied. On September 21, 2020, Defendants filed an application for interlocutory appeal with the Tennessee Supreme Court, which was denied. On October 2, 2020, Plaintiffs moved for class certification, which Defendants opposed on January 25, 2021. On April 28, 2021, the court ruled in favor of the Plaintiffs class certification. The Company filed its notice of appeal on May 4, 2021. That appeal was fully briefed and has been pending since oral argument on December 2, 2021. All trial court proceedings are stayed during the pendency of the appeal.

The Andre and Ginsberg actions were transferred to the U.S. District Court for the Middle District of Tennessee, where they were consolidated with the Franchi action. Plaintiffs filed a consolidated amended complaint on February 21, 2020, and Defendants moved to dismiss the action on March 23, 2020. That motion remains pending. While that motion was pending, the parties stipulated to allow Plaintiffs to file a further amended complaint, which Plaintiffs filed on March 31, 2021. Defendants’ motion to dismiss the new complaint was due on or before May 14, 2021. That motion was fully briefed as of July 19, 2021 and remains pending.

In the Nurlybayev action, on January 10, 2020, certain Defendants, including the Company, moved to be dismissed from the action for lack of personal jurisdiction and the remaining Defendants moved to dismiss or stay the entire action in favor of the related actions pending in Tennessee. On February 26, 2020, the Court granted Defendants' motion to dismiss the entire action in favor of the related actions pending in Tennessee. On June 19, 2020, Plaintiff Nurlybayev filed a substantially similar action in New York state court. On August 21, 2020, Defendants filed a motion to dismiss that action, which the Court granted on May 25, 2021. Plaintiff has filed a notice of appeal. Plaintiff perfected his appeal on January 21, 2022 and briefing on the appeal is in progress.

In the Sasso action, Plaintiff agreed to stay the action pending resolution of any motions to dismiss in any of the related actions. The Court so-ordered the parties’ stipulation to that effect on January 22, 2020.

In November and December 2019 and March 2020, three stockholder derivative actions were filed against the members of the Company’s board of directors, certain of the Company’s current and former officers and related entities: Doris Shenwick Trust v. Katzman et al., C.A. No. 2019-0940-MTZ (filed Nov. 22, 2019); Harts v. Katzman et al., C.A No.

2019-1027-MTZ (filed Dec. 23, 2019); and Sammons v. Katzman et al., C.A No. 2020-0169-MTZ (Mar. 5, 2020). The three derivative actions were consolidated into In Re SmileDirectClub, Inc. Derivative Litigation, C.A. No. 2019-0940-MTZ (Delaware Chancery Court) and Plaintiffs filed a consolidated amended complaint on April 8, 2020. The complaint alleges, among other things, that the defendants breached their fiduciary duties by allowing the Prospectus filed with the SEC on September 13, 2019, in connection with the Company's initial public offering, to contain materially misleading statements and by approving that the IPO proceeds be used to acquire Units and Common Stock from selling directors in connection with the IPO at an allegedly inflated price. The complaint also alleges that certain related entities aided and abetted the directors' alleged breach of fiduciary duties by selling their Common Stock and LLC Units and profiting from those sales. The complaint also alleges that the directors and related entities were unjustly enriched. The complaint seeks, among other things, disgorgement from the director and entity defendants. The Company denies any alleged wrongdoing and moved to dismiss the action. Briefing on the motion to dismiss was complete on November 6, 2020. A hearing on the motion to dismiss was held on February 17, 2021. The Court granted the motion to dismiss on May 28, 2021 and dismissed the complaint. On June 24, 2021, plaintiffs filed a Notice of Appeal. The parties submitted appellate briefing and on December 8, 2021, oral argument was held before the Delaware Supreme Court. On January 6, 2022, the Delaware Supreme Court affirmed dismissal of the derivative action on the basis of and for the reasons assigned by the Court of Chancery.

In September 2019, a putative class action on behalf of a consumer and three orthodontists was brought against the Company in the U.S. District Court for the Middle District of Tennessee, Ciccio, et al. v. SmileDirectClub, LLC, et al., Case No. 3:19-cv-00845 (M.D. Tenn.). The Plaintiffs assert claims for breach of warranty, false advertising under the Lanham Act, common law fraud, and various state consumer protection statutes relating to the Company’s advertising. Following a proactive voluntary dismissal by the majority of consumer plaintiffs, one consumer has since sought to rejoin the Middle District of Tennessee litigation or, in the alternative, to intervene, which the Court granted. That ruling has been appealed, and the Court stayed the consumer claims pending the appeal. On June 25, 2021, the appellate court reversed the district court and remanded with instructions to order the intervening plaintiff to mandatory binding arbitration. All remaining consumer claims remain stayed. Litigation is in the discovery stage. On October 13, 2021, the Court entered an Amended Scheduling Order, effectively staying merits discovery, and setting deadlines of March 30, 2022, to complete class certification fact discovery and September 2, 2022, to complete briefing on motions regarding class certification. The Company denies any alleged wrongdoing and intends to defend against this action vigorously.

Some state dental boards have established new rules or interpreted existing rules in a manner that limits or restricts the Company’s ability to conduct its business as currently conducted in other states or have engaged in conduct so as to otherwise interfere with the Company’s ability to conduct its business. We have filed actions in federal court in Alabama, Georgia, and California against the state dental boards in those states, alleging violations by the dental boards of various laws, including the Sherman Act and the Commerce Clause. While a national orthodontic association has filed Amicus Briefs in support of the dental boards in both the Georgia and Alabama litigations and has filed a motion to do the same in California (which motion was denied), the FTC and DOJ have filed joint Amicus Briefs in support of the Company in both the Alabama and Georgia matters. The California matter was amended, and an order of dismissal was entered on July 7, 2020. The Company filed notice of appeal on July 17, 2020, and the FTC and DOJ filed a joint Amicus Brief in support of the Company. Oral argument was held on July 26, 2021, with the FTC and DOJ arguing in support of the Company at oral argument as well. The appellate court has not yet issued its ruling. Both the Alabama and Georgia matters were then sent to the 11th Circuit Court of Appeals as a result of the dental boards in both states appealing the lower court’s decisions. Oral argument before the 11th Circuit Court of Appeals occurred in the Georgia matter on May 20, 2020, and in the Alabama matter on July 8, 2020. The FTC and DOJ participated in oral arguments in support of the Company. The DOJ’s antitrust chief presented in the Alabama matter. On August 11, 2020, the 11th Circuit Court of Appeals affirmed the Georgia district court’s denial of the board members’ motion to dismiss. On December 8, 2020, the 11th Circuit Court of Appeals voted to have a rehearing en banc. The FTC and DOJ filed an amicus and participated in oral argument that was held on February 23, 2021. On July 20, 2021, the 11th Circuit Court of Appeals ruled in the Company’s favor, finding that the Georgia Dental Board did not have an interlocutory right of appeal and therefore denied the Georgia Board’s appeal. On July 29, 2021, the 11th Circuit Court of Appeals also denied the Alabama Dental Board’s appeal. Both cases were remanded to the respective District Courts to proceed accordingly into the discovery phase.

On November 22, 2021, the Georgia Board filed a motion to dismiss in the Northern District of Georgia. On January 6, 2022, a hearing was held on the motion to dismiss. The parties await a final order and discovery is ongoing.

On August 17, 2021, the Alabama Dental Board and the Company entered into a tentative settlement agreement, subject to the FTC’s proposed Consent Order being entered into by the Board, precluding the Alabama Dental Board from requiring onsite supervision for scanning by doctors in SmileShops. On September 28, 2021, the FTC issued its press release and memorandum regarding its proposed Consent Order with the Alabama Dental Board which precludes the Board from engaging in conduct intended to preclude teledentistry in the State of Alabama or to preclude dentists and orthodontists from using the Company’s teledentistry platform to treat patients. On December 22, 2021, the Consent Order was finalized, and the District Court in Alabama thereafter entered its order approving the joint motion for dismissal of the lawsuit per the terms of the settlement reached between the parties.

On July 12, 2021, the Australian Competition & Consumer Commission filed an Originating Application against SmileDirectClub, LLC and the Company’s Australian affiliate SmileDirectClub Aus Pty Ltd. The Originating Application alleges certain misstatements by the Company in connection with the availability of consumers having the ability to have private health care coverage cover a portion of their costs when seeking treatment through the Company’s telehealth platform. The Company has denied any wrongdoing and has filed its Concise Response to the Statement of Claim. Should the matter not be resolved, trial has been scheduled to commence on April 17, 2023.

In March 2019, a final arbitration award was issued in an arbitration proceeding brought by the Company alleging that one of our former members, Align, violated certain restrictive covenants set forth in its operating agreement. The arbitrator ruled that Align breached both the non-competition and confidentiality provisions of the Company’s operating agreement and that, as a result, Align was required to close its Invisalign Stores, return all of the Company’s confidential information, and sell its membership units to the Company or certain of its pre-IPO unitholders for an amount equal to the balance of Align’s capital account as of November 2017. The arbitrator also extended the non-competition period to which Align is subject through August of 2022 and prohibited Align from using the Company’s confidential information in any manner going forward. The Company paid Align $54,000, pursuant to a promissory note payable over 24 months through March 2021, in full redemption of Align’s membership units pursuant to this ruling. The ruling has been confirmed in its entirety in the circuit court of Cook County, Chicago, Illinois, but Align continued to object to the purchase price and repurchase documentation despite the arbitration ruling and its confirmation, and filed a subsequent arbitration proceeding disputing the $54,000 redemption amount and seeking an additional $43,400. Arbitration was held in December 2020. The arbitrator reached final decision in March 2021 and the Company paid Align the remaining amount of $43,400 (which it had reserved) plus accrued interest.

In December 2020, a class action complaint was filed in the Illinois state court: Stacy Benbow et al. v. SmileDirectClub, Inc. et al., 2020 CH 07269 (Cook County Circuit Court filed 12/14/20). The complaint alleges violations of the Telephone Consumer Protection Act and seeks to represent a nationwide class of similarly situated persons. The complaint seeks injunctive relief, statutory damages, and attorneys’ fees and costs. A tentative settlement was approved by the court and the Company has recorded an estimated loss of $4,800 related to such tentative settlement. Notice to the class was sent on March 20, 2021, and final approval was set for May 19, 2021. On May 19, 2021, the final approval was granted by the Cook County Circuit Court. The final cost of the settlement was approximately $4,000.

Tax Receivable Agreement

As described in Note 9, the Company is a party to the Tax Receivable Agreement pursuant to which SDC Inc. is contractually committed to pay the Continuing LLC Members 85% of the amount of any tax benefits that SDC Inc. actually realizes, or in some cases is deemed to realize, as a result of certain transactions. The Company is not obligated to make any payments under the Tax Receivable Agreement until the tax benefits associated with the transactions that gave rise to the payments are realized. TRA Payments are contingent upon, among other things, (i) generation of future taxable income over the term of the Tax Receivable Agreement and (ii) future changes in tax laws. If the Company does not generate sufficient taxable income in the aggregate over the term of the Tax Receivable Agreement to utilize the tax benefits, then it will not be required to make the related TRA Payments. During the years ended December 31, 2021 and 2020, the Company recognized

no liabilities relating to its obligations under the Tax Receivable Agreement, after concluding that it was not probable that the Company would have sufficient future taxable income over the term of the Tax Receivable Agreement to utilize the related tax benefits. There were no transactions subject to the Tax Receivable Agreement for which the Company recognized the related liability, as the Company concluded that it would not have sufficient future taxable income to utilize all of the related tax benefits.

Other Tax Matters

We operate in numerous jurisdictions in which taxing authorities may challenge our position with respect to income and non-income-based taxes. We routinely receive inquiries and may also from time to time receive challenges or assessments from these taxing authorities. With respect to non-income-based taxes, we recognize liabilities when we believe it is probable that amounts will be owed to the taxing authorities and such amounts are estimable. For example, in most countries we charge and remit Value Added Tax (“VAT”) when procuring goods and services, or providing services, within the normal course of business. VAT receivables are established in jurisdictions where input VAT exceeds output VAT and are recoverable through the filing of refund claims. These receivables have inherent audit and collection risks unique to the specific jurisdictions that evaluate our refund claims. We have received a challenge from a non-US taxing authority for VAT related to certain sales made and services provided by certain of the Company’s subsidiaries. The Company believes these transactions are exempt from VAT and has filed legal actions challenging the taxing authority’s application of VAT to them. Discussions on these matters are ongoing. The Company believes its interpretation of these VAT rules is appropriate, and that it will be successful in its challenge against the taxing authority’s assessments. Accordingly, the Company does not believe it is probable that it will incur a loss related to these matters. However, the interpretation and application of these VAT rules is an unsettled issue, and the resolution of tax and regulatory matters is unpredictable. If it is determined in these proceedings that VAT applies to some or all of these various transactions, the Company could incur a charge that ranges between zero and $17,900 for these matters, including any interest and penalties associated with these matters and the amount, if any, of VAT the Company might subsequently recover related to its input costs.

Segment Reporting [Abstract]

Segment Reporting

Segment ReportingThe Company provides aligner products. The Company’s chief operating decision maker (“CODM”) views the operations and manages the business primarily on a consolidated basis, however, the CODM regularly evaluates, monitors, and makes operational decisions based on the results of operations segmented between North America (defined as the U.S. and Canada) and Rest of World. For the year ended December 31, 2021, approximately 82.4% of the Company’s revenues were generated by sales within North America, and substantially all of its net property, plant and equipment was within North America. Below are the tabular results of operations summarized at the revenue and operating loss level for North America and the Rest of World for the years ended December 31, 2021 and 2020. For the year ended December 31, 2019, the results of operations were not segregated and presented to the chief operating decision maker at this same level and therefore are not presented herein.

Subsequent Events

On January 24, 2022, the Company announced that following an evaluation of its business and the continuing macroeconomic factors impacting consumers, the Company is taking specific actions that will focus efforts on supporting the key growth initiatives that will produce the highest return on investment. These initiatives include the expansion of its professional channel, the SmileDirectClub Partner Network; innovations to its aligner products so as to allow the Company to capture greater market share of the teen and higher-household income demographics; its burgeoning oral care product business; and SmileShop growth in markets with strong consumer demand. Expansion into new international markets will be paused while the global economy recovers from pandemic and macroeconomic pressures that have contributed to challenging operating environments.

In connection with these operational changes, the Company announced it has suspended operations in Mexico, Spain, Germany, Netherlands, Austria, Hong Kong, Singapore and New Zealand. The Company will continue to operate in and scale its presence in the United States, Canada, United Kingdom, Ireland, France and Australia. With these changes, the Company initiated a reduction in workforce to right-size its operating structure so it is tailored to the countries in which the Company will continue to operate and focus.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2021

Accounting Policies [Abstract]

Basis of Presentation and Consolidation

Basis of Presentation and ConsolidationThe preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

The consolidated financial statements include the accounts of SDC Inc., which consolidates SDC Financial and its wholly-owned subsidiaries, as well as accounts of contractually affiliated professional corporations (“PCs”) managed by the Company.

The consolidated financial statements include the accounts of variable interest entities in which the Company is the primary beneficiary under the provisions of Accounting Standards Codification (‘‘ASC”) Topic 810, ‘‘Consolidation.” At December 31, 2021, the variable interest entities include 53 dentist owned PCs, and at December 31, 2020 the variable interest entities included 54 dentist owned PCs. The Company is a dental service organization and does not engage in the practice of dentistry. All clinical services are provided by dentists and orthodontists who are engaged as independent contractors or otherwise engaged by the dentist-owned PCs. The Company contracts with the PCs and dentists and orthodontists through a suite of agreements, including but not limited to, management services agreements, supply agreements, and licensing agreements, pursuant to which the Company provides the administrative, non-clinical management services to the PCs and independent contractors. The Company has the contractual right to manage the activities that most significantly impact the variable interest entities’ economic performance through these agreements without engaging in the corporate practice of dentistry. Additionally, the Company would absorb substantially all of the expected losses of these

entities should they occur. The accompanying consolidated statements of operations reflect the revenue earned and the expenses incurred by the PCs.

Management Use of Estimates

Management Use of Estimates

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that impact the reported amounts. On an ongoing basis, the Company evaluates its estimates, including those related to the fair values of financial instruments, useful lives of property, plant and equipment, revenue recognition, equity-based compensation, long-lived assets, and contingent liabilities, among others. In connection with its credit facility with HPS Investment Partners, the Company issued warrants to certain affiliates of HPS Investment Partners. The warrants were recorded at fair value at the time of issuance within equity on the consolidated balance sheet using the Black-Scholes option pricing model (see Note 10). Each of these estimates varies in regard to the level of judgment involved and its potential impact on the Company’s financial results. Estimates are considered critical either when a different estimate could have reasonably been used, or where changes in the estimate are reasonably likely to occur from period to period, and such use or change would materially impact the Company’s financial condition, results of operations, or cash flows. Actual results could differ from those estimates.

Revenue Recognition

Revenue Recognition

The Company’s revenues are derived primarily from sales of aligners, impression kits, whitening gel, and retainers, and interest earned through its SmilePay financing program. Revenue is recorded for all customers based on the amount that is expected to be collected, which considers implicit price concessions, discounts, and cancellations and refunds from customer returns.

The Company 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 (“SSP”) and allocation of consideration from a 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, usage rates (the number of times a customer is expected to order additional aligners), costs, and expected margin, which may vary over time depending upon the unique facts and circumstances related to each performance obligation, in making these estimates. Further, the Company’s process for estimating usage rates requires significant judgment and evaluation of inputs, including historical data and forecasted usages. Changes in the allocation of the SSP between performance obligations will not affect the amount of total revenues recognized for a particular contract. The Company uses the expected cost plus a margin approach to determine the SSP for performance obligations, and discounts are allocated to each performance obligation based on the relative SSP. However, any material changes in the allocation of the SSP could impact the timing of revenue recognition, which may have a material effect on the Company’s financial position and result of operations as 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.

The Company estimates the amount expected to be collected based upon management’s assessment of historical write-offs, expected net collections including implicit price concessions, and cancellations and refunds from customer returns, business and economic conditions, and other collection indicators. Management relies on the results of detailed reviews of historical write-offs, cancellations, returns, and collections as a primary source of information in estimating the amount of contract consideration expected to be collected. Uncollectible receivables are written-off in the period management believes it has exhausted its ability to collect payment from the customer. The Company believes its analysis provides reasonable estimates of its revenues and valuations of its accounts receivable.

A description of the revenue recognition for each product sold by the Company is detailed below.

Aligners and Impression Kits: The Company enters into contracts with customers for aligner sales that involve multiple future performance obligations. The Company determined that aligner sales comprise the following distinct performance

obligations: initial aligners, touch-up aligners, and retainers for international sales only which can occur at any time throughout the treatment plan (which is typically between five months to ten months) upon the direction of and prescription from the treating dentist or orthodontist.

The Company allocates revenues for each performance obligation based on its SSP and recognizes the revenues as control of the performance obligation is transferred upon shipment of the aligners. The Company recognizes aligner revenue on amounts expected to be collected during the course of the treatment plan.

The Company bills its customers either upfront for the full cost of aligners or monthly through its SmilePay financing program, which involves a down payment and a fixed amount per month for up to 24 months. The Company’s accounts receivable related to the SmilePay financing program are reported at the amount expected to be collected on the consolidated balance sheets, which considers implicit price concessions. Financing revenue from its accounts receivable is recognized based on the contractual market interest rate with the customer, net of implicit price concessions. There are no fees or origination costs included in accounts receivable.

The Company sells doctor-prescribed impression kits to its customers as an alternative to an in-person visit at one of its SmileShops, popup locations, or Partner Network locations, comprised of affiliated dentist and orthodontist offices, where the customer receives a free oral digital imaging of their teeth. The Company combines the sales of its impression kits with aligner sales and recognizes the revenues as control of the performance obligation is transferred upon shipment of the aligners. The Company estimates the amount of impression kit sales that do not result in an aligner therapy treatment plan and recognizes such revenue when aligner conversion becomes remote.

Retainers and Other Products: The Company sells retainers and other products (such as whitening gel and tooth brushes) to customers, which can be purchased on the Company’s website or certain retail outlets. The sales of these products are independent and separate from the customer’s decision to purchase aligner therapy for domestic sales. The Company determined that the transfer of control for these performance obligations occurs as the title of such products passes to the customer or retail partner.

Deferred Revenue: Deferred revenue represents the Company’s contract liability for performance obligations associated with sales of aligners.

Shipping and Handling Costs

Shipping and handling charges are recorded in cost of revenues in the consolidated statements of operations upon shipment. The Company incurred approximately $22,892, $23,036 and $19,000 in outsourced shipping expenses for the years ended December 31, 2021, 2020 and 2019, respectively.

Cost of Revenues

Cost of revenues includes the total cost of products produced and sold. Such costs include direct materials, direct labor, overhead costs (occupancy costs, indirect labor, and depreciation), fees retained by doctors, freight and duty expenses associated with moving materials from vendors to the Company’s facilities and from its facilities to the customers, and adjustments for shrinkage (physical inventory losses), lower of cost or net realizable value, slow moving product and excess inventory quantities.

Marketing and Selling, General and Administrative Expenses

Marketing and Selling ExpensesMarketing and selling expenses include direct online and offline marketing and advertising costs, costs associated with intraoral imaging services, selling labor, and occupancy costs of SmileShop locations. All marketing and selling expenses, including advertising, are expensed as incurred.

General and Administrative Expenses

General and administrative expenses include payroll and benefit costs for corporate team members, equity-based compensation expenses, occupancy costs of corporate facilities, bank charges and costs associated with credit and debit card interchange fees, outside service fees, and other administrative costs, such as computer maintenance, supplies, travel, and lodging.

Depreciation and Amortization

Depreciation and Amortization

Depreciation includes expenses related to the Company’s property, plant and equipment, including capital leases. Amortization includes expenses related to definite-lived intangible assets and capitalized software. Depreciation and amortization is calculated using the straight-line method over the useful lives of the related assets, ranging from three to ten years. Leasehold improvements are amortized using the straight-line method over the shorter of the related lease terms or

their useful lives. Depreciation and amortization is included in cost of revenues, selling expenses, and general and administrative expenses depending on the purpose of the related asset.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The Company measures the fair value of financial instruments 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. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

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.

Level 3 — Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability.

The Company’s financial instruments consist of cash, current and non-current receivables, accounts payable, debt instruments, and derivative financial instruments. Due to their short-term nature, the carrying values of cash, current receivables, and trade payables approximate current fair value at each balance sheet date.

Derivatives Financial Instruments

Derivative Financial Instruments

The Company accounts for derivative financial instruments in accordance with applicable accounting standards for such instruments and hedging activities, which require that all derivatives are recorded on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability. The Company had no outstanding derivatives at December 31, 2021

or 2020; however, the Company may enter into derivative contracts that are intended to economically hedge a certain portion of its risk, even though hedge accounting does not apply or the Company elects not to apply the hedge accounting standards.

Certain Risks and Uncertainties

Certain Risks and Uncertainties

The Company’s operating results depend to a significant extent on the ability to market and develop its products. The life cycles of the Company’s products are difficult to estimate due, in part, to the effect of future product enhancements and competition. The inability to successfully develop and market the Company’s products as a result of competition or other factors would have a material adverse effect on its business, financial condition, and results of operations.

The Company provides credit to customers in the normal course of business. The Company maintains reserves for potential credit losses and such losses have been within management’s expectations. No individual customer accounted for 1% or more of the Company’s accounts receivable at December 31, 2021 or 2020, or net revenue for the years ended December 31, 2021, 2020 and 2019.

Some of the Company’s products are considered medical devices and are subject to extensive regulation in the U.S. and internationally. The regulations to which the Company is subject are complex. Regulatory changes could result in restrictions on the Company’s ability to carry on or expand its operations, higher than anticipated costs or lower than anticipated sales. The failure to comply with applicable regulatory requirements may have a material adverse impact on the Company.

The Company’s reliance on international operations exposes it to related risks and uncertainties, including difficulties in staffing and managing international operations, such as hiring and retaining qualified personnel; 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, operating results may be harmed.

The Company purchases certain inventory from sole suppliers, and the inability of any supplier or manufacturer to fulfill the supply requirements could materially and adversely impact its future operating results.

Cash

Cash

Cash consists of all highly liquid investments with original maturities of less than three months. Cash is held in various financial institutions in the U.S. and internationally.

Inventories

Inventories

Inventories are stated at the lower of cost or net realizable value using the first-in, first-out method of inventory accounting. Inventory consists of raw materials for producing impression kits and aligners and finished goods. Inventory is net of shrinkage and obsolescence.

Property, Plant and Equipment, net

Property, Plant and Equipment, Net

Property, plant and equipment are stated at cost less accumulated depreciation and amortization. Routine maintenance and repairs are charged to expense as incurred. At the time property, plant and equipment are retired from service, the cost and accumulated depreciation or amortization are removed from the respective accounts and the related gains or losses are reflected in the consolidated statements of operations.

Leases

Leases

On January 1, 2020, the Company adopted the new leases standard using the modified retrospective transition method, which requires that it recognizes leases differently pre- and post-adoption. The Company categorizes leases at their inception

as either operating or finance leases. Lease agreements cover certain retail locations, office space, warehouse, manufacturing and distribution space and equipment. Operating leases are included in operating lease right-of-use assets, other current liabilities, and long-term right-of-use operating lease obligations in the consolidated balance sheets. Finance leases are included in property, plant and equipment, net, current portion of long-term debt, and long-term debt.

Leased assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The Company uses a secured incremental borrowing rate as the discount rate for determining the present value of lease payments when the rate implicit in the contract is not readily determinable. Leases that have a term of twelve months or less upon commencement date are considered short-term in nature. Accordingly, short-term leases are not included on the consolidated balance sheets and are expensed on a straight-line basis over the lease term, which commences on the date we have the right to control the property.

Internally Developed Software Costs

Internally Developed Software CostsThe Company generally provides services to its customers using software developed for internal use. The costs that are incurred to develop such software are expensed as incurred during the preliminary project stage. Once certain criteria have been met, direct costs incurred in developing or obtaining computer software are capitalized. Training and maintenance costs are expensed as incurred. Capitalized software costs are included in property, plant and equipment in the consolidated balance sheets and are amortized over useful life of the software which is generally a three-year to five-year period.

Impairment

ImpairmentThe Company evaluates long-lived 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 generate. Factors the Company considers 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. The Company’s estimates of future cash flows attributable to long-lived assets require significant judgment based on its 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 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.

Debt Issuance Costs

Debt Issuance Costs

The Company records debt issuance costs related to its term debt as direct deductions from the carrying amount of the debt. The costs are amortized to interest expense over the life of the debt using the effective interest method.

Income Taxes

Income Taxes

SDC Inc. is the managing member of SDC Financial and, as a result, consolidates the financial results of SDC Financial in the consolidated financial statements. SDC Financial and its subsidiaries are limited liability companies and have elected to be taxed as partnerships for income tax purposes except for a subsidiary, SDC Holding, LLC (‘‘SDC Holding”) and its domestic and foreign subsidiaries, which are taxed as corporations. As such, SDC Financial does not pay any federal income taxes, as any income or loss is included in the tax returns of the individual members. SDC Financial does pay state income

tax in certain jurisdictions, and the Company’s income tax provision in the consolidated financial statements reflects the income taxes for those states. Additionally, certain wholly-owned entities taxed as corporations are subject to federal, state, and foreign income taxes, in the jurisdictions in which they operate, and accruals for such taxes are included in the consolidated financial statements. The Company further evaluates deferred tax assets in each jurisdiction and recognizes associated benefits when positive evidence of realization exceeds negative evidence, and otherwise records valuation allowances as necessary.

The Company computes the provision for income taxes using the liability method and recognizes deferred tax assets and liabilities for temporary differences between financial statement and income tax bases of assets and liabilities, as well as for operating loss and tax credit carryforwards. The Company measures deferred tax assets and liabilities using tax rates applicable to taxable income in effect for the years in which those tax assets are expected to be realized or settled and provides a valuation allowance against deferred tax assets when it cannot conclude that it is more likely than not that some or all deferred tax assets will be realized. In addition, the Company recognizes tax benefits from uncertain tax positions only if it expects that its tax positions are more likely than not that they will be sustained, based on the technical merits of the positions, on examination by the jurisdictional tax authority. The Company recognizes any accrued interest and penalties to unrecognized tax benefits as interest expense and income tax expense, respectively.

Tax Receivable Agreement

In connection with the Reorganization Transactions and the IPO, the Company entered into a Tax Receivable Agreement with the Continuing LLC Members, pursuant to which SDC Inc. agreed to pay the Continuing LLC Members 85% of the amount of cash tax savings, if any, in U.S. federal, state, and local income tax or franchise tax that SDC Inc. actually realizes as a result of (a) the increases in tax basis attributable to exchanges by Continuing LLC Members and (b) tax benefits related to imputed interest deemed to be paid by SDC Inc. as a result of the Tax Receivable Agreement. The Company recognizes this contingent liability in its consolidated financial statements when amounts become probable as to incurrence and estimable in amount.

Recent Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In January 2021 the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standard Update (“ASU”) 2016-13, “Financial Instruments—Credit Losses” (Topic 326). The FASB issued this update 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 adoption of this standard did not have a material impact on the Company’s consolidated financial statements and related disclosures.

In January 2021, the Company adopted FASB ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." This standard simplified the accounting for income taxes by eliminating certain exceptions to the guidance in Topic 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an period and the recognition of deferred tax liabilities for outside basis differences. The guidance also simplified aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill and allocating consolidated income taxes to separate financial statements of entities not subject to income tax. The Company adopted the provisions of this guidance effective January 1, 2021 using the modified retrospective method of adoption which required no cumulative-effect adjustment to retained earnings as of the beginning of the period.

In January 2021, the Company adopted FASB ASU 2020-06, “Accounting for Convertible Instruments and Contracts in an Entity's Own Equity,” which eliminates most of the guidance in Subtopic 470-20 that requires separate accounting for embedded conversion features in convertible debt arrangements. Further, ASU 220-06 removes some of the conditions in

Subtopic 815-40-25, “Contracts on an Entity's own Equity,” that are required for equity classification, including the requirement for equity contracts to permit settlement in unregistered shares. The Company adopted the provisions of this guidance effective January 1, 2021, using the modified retrospective method of adoption which required no cumulative-effect adjustment to retained earnings as of the beginning of the period. The Company applied the provisions of this guidance to the recently issued 2026 Convertible Senior Notes and related capped call transactions.

Allowance for credit losses

Allowance for credit losses and other revenue adjustments: The Company records a provision to maintain an allowance for credit losses and other revenue adjustments that result from the failure or inability of its members or other partners to make required payments deemed collectible when the product was delivered, or customer returns resulting in cancellations or refunds. When determining the allowances for member receivables, the Company considers the probability of recoverability of accounts receivable based on past experience, taking into account current collection trends and general economic factors, including bankruptcy rates. The Company also considers future economic trends in its estimation of expected credit losses over the lifetime of the asset. Credit risks are assessed based on historical write-offs, cancellations, and adjustments, net of recoveries, as well as an analysis of the aged accounts receivable balances. Accounts receivable may be fully reserved for when specific collection issues are known to exist, such as a history of missed scheduled payments and customer service or production issues.

Schedule of Antidilutive Securities Excluded from Computation of Earnings (Loss) Per Share

Due to their anti-dilutive effect, the following securities have been excluded from diluted net earnings (loss) per share in the periods presented:

	Years Ended December 31,
	2021	2020	2019
Options	1,664,122	1,679,339	1,744,556

Shares issuable under the Notes (if converted method)(1)	41,389,822	—	—

(1) In connection with the issuance of the Notes, the Company entered into Capped Call Transactions, which were not included for purposes of calculating the number of diluted shares outstanding, as their effect would have been anti-dilutive. The Capped Call Transactions are expected to reduce the potential dilution to the Company’s common stock (or, in the event a conversion of the Notes is settled in cash, to reduce its cash payment obligation) in the event that at the time of conversion of the Notes the Company’s common stock price exceeds the conversion price of the Notes.
