CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q 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. These statements are often, but not always, made through the use of words or phrases such as “anticipates,” “believes,” “can,” “could,” “may,” “predicts,” “potential,” “should,” “will,” “estimate,” “plans,” “projects,” “continuing,” “ongoing,” “expects,” “intends,” and similar words or phrases. 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” in this report and in our Annual Report on Form 10-K for the year ended December 31, 2020. 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, including international expansion; 

•our ability to effectively execute our business strategies, implement new initiatives, and improve efficiency; 

•our sales and marketing efforts; 

•our manufacturing capacity and performance and our ability to reduce the per unit production cost of our clear aligners; 

•our ability to obtain regulatory approvals for any new or enhanced products; 

•our estimates regarding revenues, expenses, capital requirements, and needs for additional financing; 

•our ability to effectively market and sell, consumer acceptance of, and competition for our clear aligners in new markets; 

•our relationships with retail partners and insurance carriers; 

•our research, development, commercialization, and other activities and projected expenditures; 

•changes or errors in the methodologies, models, assumptions, and estimates we use to prepare our financial statements, make business decisions, and manage risks; 

•our current business model is dependent, in part, on current laws and regulations governing remote healthcare and the practice of dentistry, and changes in those laws, regulations, or interpretations that are inconsistent with our current business model could have a material adverse effect on our business; 

•our relationships with our freight carriers, suppliers, and other vendors; 

•our ability to maintain the security of our operating systems and infrastructure (e.g., against cyberattacks); 

•the adequacy of our risk management framework; 

•our cash needs and ability to raise additional capital, if needed; 

•our intellectual property position; 

•our exposure to claims and legal proceedings;

•our ability to remain in compliance with our debt covenants;

•our ability to manage the COVID-19 pandemic, including the protracted duration of COVID-19 and the potential resurgence of COVID-19 infections, through voluntary and regulatory containment measures and the related impacts on our business;

•our ability to 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, labor instability, and capacity reduction; and

•other factors and assumptions described in this Quarterly Report on Form 10-Q.

If one or more of the factors affecting our forward-looking information and statements proves incorrect, our actual results, performance or achievements could differ materially from those expressed in, or implied by, forward-looking information and statements. Therefore, we caution not to place undue reliance on any forward-looking information or statements. The effect of these factors is difficult to predict. Factors other than these also could adversely affect our results, and the reader should not consider these factors to be a complete set of all potential risks or uncertainties. New factors emerge from time to time, and management cannot assess the impact of any such factor on our business or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statement. Any forward-looking statements only speak as of the date of this document, and we undertake no obligation to update any forward-looking information or statements, whether written or oral, to reflect any change, except as required by law. All forward-looking statements attributable to us are expressly qualified by these cautionary statements.

You should read this Quarterly Report on Form 10-Q and the documents that we reference in this Quarterly Report on Form 10-Q and have filed with the Securities and Exchange Commission (“SEC”) as exhibits to this Quarterly Report on Form 10-Q with the understanding that our actual future results, levels of activity, performance, and events and circumstances may be materially different from what we expect.

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

Notes to Condensed Consolidated Financial Statements (Unaudited) (Continued)

(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 condensed 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 accompanying interim condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the SEC and, in the opinion of management, reflect all normal recurring adjustments necessary for a fair presentation of results for the unaudited interim periods presented. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted. The results of operations for the interim period are not necessarily indicative of the results to be obtained for the full fiscal year. All intercompany balances and transactions are eliminated in consolidation.

The interim condensed 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 interim condensed 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 September 30, 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

SmileDirectClub, Inc.

Notes to Condensed Consolidated Financial Statements (Unaudited) (Continued)

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

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 condensed 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 $5,674 and $34,783 during the three and nine months ended September 30, 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 three and nine months ended September 30, 2021, we incurred one-time charges of approximately $1,473 and $3,137, respectively, 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 interim condensed 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 interim condensed consolidated balance sheet using the Black-Scholes option pricing model (see Note 9). 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 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 and expected net collections, business and economic conditions, and other collection indicators. Management relies on the results of detailed reviews of historical write-offs and collections as a primary source of information in estimating the amount of contract consideration expected to be collected and implicit price concessions. 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

SmileDirectClub, Inc.

Notes to Condensed Consolidated Financial Statements (Unaudited) (Continued)

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

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 interim condensed 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:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Aligner revenue, net of implicit price concessions	$	108,273	$	139,279	$	418,590	$	388,111
Financing revenue, net of implicit price concessions	10,887		12,042		33,140		37,428
Retainers and other products revenue	18,523		17,180		59,595		46,685
Total revenue	$	137,683	$	168,501	$	511,325	$	472,224
Implicit price concessions included in total revenue	$	12,370	$	15,363	$	38,861	$	50,051

Deferred Revenue: Deferred revenue represents the Company’s contract liability for performance obligations associated with sales of aligners. During the nine months ended September 30, 2021 and 2020, the Company recognized $511,325 and $472,224 of revenue, respectively, of which $22,348, and $19,547 was previously included in deferred revenue on the condensed consolidated balance sheets as of December 31, 2020 and 2019, respectively.

Allowance for credit losses: The Company records a provision to maintain an allowance for credit losses that result from the failure or inability of its members or other partners to make required payments deemed collectible when the product was delivered. 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

SmileDirectClub, Inc.

Notes to Condensed Consolidated Financial Statements (Unaudited) (Continued)

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

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 of receivables was as follows:

	Accounts Receivable Allowance for Credit Losses
Balance at January 1, 2021	$	39,448
Current period provision for expected credit losses	38,102
Write-offs and other adjustments charged against the allowance, net of recoveries	(44,816)
Balance at September 30, 2021	$	32,734

Shipping and Handling Costs

Shipping and handling charges are recorded in cost of revenues in the condensed consolidated statements of operations upon shipment. The Company incurred approximately $4,901, $17,578, $5,891 and $18,516 in outsourced shipping expenses for the three and nine months ended September 30, 2021 and 2020, 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 three and nine months ended September 30, 2021 and 2020, the Company incurred marketing, selling, and advertising costs of $96,175, $289,241, $66,722, and $243,564, 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.

SmileDirectClub, Inc.

Notes to Condensed Consolidated Financial Statements (Unaudited) (Continued)

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

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

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Cost of revenues	$	6,679	$	5,944	$	20,608	$	17,385
Marketing and selling expenses	1,340		1,635		4,384		4,906
General and administrative expenses	10,467		6,463		26,663		17,108
Total	$	18,486	$	14,042	$	51,655	$	39,399

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 9) as of September 30, 2021 and December 31, 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 September 30, 2021 the fair value of the debt facility was approximately $525,000 compared to its carrying value of $728,895.

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 September 30, 2021 or December 31, 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 September 30, 2021 or December 31, 2020, or net revenue for the three and nine months ended September 30, 2021 and 2020.

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 condensed 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. See “Recently Adopted Accounting Pronouncements—ASU No. 2016-02” below for more information. The Company categorizes leases at their inception as either operating or finance leases. Lease agreements cover certain retail locations, office space, warehouse, manufacturing

SmileDirectClub, Inc.

Notes to Condensed Consolidated Financial Statements (Unaudited) (Continued)

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

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 condensed 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 condensed 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 condensed consolidated balance sheets and are amortized over a three-year period. During the three and nine months ended September 30, 2021 and 2020, the Company capitalized $4,135, $12,436, $3,555, and $10,938, respectively, of internally developed software costs. Amortization expense for internally developed software was $5,686, $12,433, $2,091, and $5,373 for the three and nine months ended September 30, 2021, and 2020, respectively.

Impairment

The Company evaluates long-lived assets (including finite-lived intangible assets) for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. An asset or asset group is considered impaired if its carrying amount exceeds the future undiscounted net cash flows that the asset or asset group is expected to 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 condensed 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 condensed consolidated financial

SmileDirectClub, Inc.

Notes to Condensed Consolidated Financial Statements (Unaudited) (Continued)

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

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 condensed 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 condensed consolidated financial statements when amounts become probable as to incurrence and estimable in amount.

Recently Adopted Accounting Pronouncements

In January 2021 the Company adopted FASB 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 condensed 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 interim 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 three and nine months ended September 30, 2021, or 2020.

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

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. As a result of these changes, the Company incurred one-time charges of $1,473 and $3,137 for the three and nine months ended September 30, 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

Note 8—Income Taxes

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 condensed 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 (benefit) 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.

Total income tax provision	$	(119)	$	1,190	$	1,576	$	1,745

At September 30, 2021 the Company had unused federal net operating loss carryforwards (tax effected) for federal income tax purposes of approximately $60,137, 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 $33,658, which expire from 2029 through 2035. The Company also had unused net operating loss carryforwards (tax effected) for foreign income tax purposes of approximately $4,260. 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 September 30, 2021, the Company maintained a valuation allowance of approximately $295,085 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.

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

SmileDirectClub, Inc.

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

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 three and nine months ended September 30, 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.

Note 9—Long-Term Debt

The Company’s debt and finance lease obligations are comprised of the following:

	September 30,		December 31,

2026 Convertible Senior Notes, net of unamortized financing costs $18,606 and $0, respectively	$	728,895	$	—

Total long-term debt	$	733,184	$	392,939

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 nine months ended September 30, 2021, the Company amortized under the effective interest rate method $2,732 of deferred financing costs.

SmileDirectClub, Inc.

Notes to Condensed Consolidated Financial Statements (Unaudited) (Continued)

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

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

SmileDirectClub, Inc.

Notes to Condensed Consolidated Financial Statements (Unaudited) (Continued)

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

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.

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 nine months ended September 30, 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 condensed consolidated statements of operations for the nine months ended September 30, 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.

SmileDirectClub, Inc.

Notes to Condensed Consolidated Financial Statements (Unaudited) (Continued)

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

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 condensed 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 15, 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 condensed consolidated statement of operations. As of September 30, 2021, the Company has $0 outstanding under this promissory note.

Future Maturities

Annual future maturities of long-term debt, excluding finance lease obligations, and unamortized financing costs, are as follows:

	2026 Convertible Senior Notes
2021 (remaining)	$	—
2022	—
2023	—
2024	—
2025	—
2026	747,500
Total	$	747,500

Note 10—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 September 30, 2021, SDC Inc. had 119,103,923 shares of Class A common stock outstanding, which

SmileDirectClub, Inc.

Notes to Condensed Consolidated Financial Statements (Unaudited) (Continued)

(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 September 30, 2021, SDC Inc. had a 30.6% economic ownership interest in SDC Financial.

Note 11—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 nine months ended September 30, 2021 and 2020. Prior to the IPO and Reorganization Transactions, SDC Inc. was not impacted by SDC Financial.

Note 12—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 nine months ended September 30, 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		9.3	—
Exercised	—	—		—	—

Forfeited	—	—		—	—
Outstanding at September 30, 2021	1,729,339	$	22.69	8.0	$	—
Exercisable at September 30, 2021	597,816	$	23.00	7.9	$	—

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 nine months ended September 30, 2021, include an expected

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

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 pursuant to time-based vesting terms. As of September 30, 2021, unrecognized compensation expense related to the Options was $5,844. This expense is expected to be recognized over a weighted average period of 1.1 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 September 30, 2021, unrecognized compensation expense related to unvested IBA and non-IBA RSUs was $46,673. This expense is expected to be recognized over a weighted average period of 2.5 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 $37,659 and $38,189 for the nine months ended September 30, 2021 and 2020, respectively. Amounts are included in general and administrative expense on the condensed consolidated statements of operations.

Note 13—Earnings 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 condensed consolidated financial statements.

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:

	Three Months Ended September 30,		Nine Months Ended September 30,
	2021	2020	2021	2020

Shares issuable under the Notes (if converted method)(1)	41,389,822	—	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.

Note 14—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, subject to federal limits. For the nine months ended September 30, 2021 and 2020, the Company matched (i) 100% of employees’ salary deferral contributions up to 3% and (ii) 50% of employees’ salary deferral contributions from 3% to 5% of employees’ eligible compensation. The Company contributed $2,359 and $2,551 to the 401(k) plan for the nine months ended September 30, 2021 and 2020, respectively.

Note 15—Related Party Transactions

Products and Services

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 $4,806 and $4,305 for the nine months ended September 30, 2021 and 2020, 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 16—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. 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 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 of the actions are in the preliminary stages. The Company denies any alleged wrongdoing and intends to vigorously defend against these actions. On March 31, 2021, the Plaintiffs filed an amended complaint. Defendants motion to dismiss the new complaint was filed on May 14, 2021 and was fully briefed as of July 19, 2021. The motion currently remains pending.

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 as of October 6, 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, the Defendants moved to dismiss or stay the entire action in favor of the related actions pending in Tennessee, which motion was granted and the case was dismissed on February 26, 2020. 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 is fully briefed and remains pending. 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.

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 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 consolidated complaint asserts claims against certain defendants for breaches of fiduciary duty, aiding and abetting those breaches, and unjust enrichment. The consolidated complaint seeks, among other things, disgorgement of allegedly unlawful profits from selling common stock and LLC Units. The Company has moved to dismiss the action. Briefing on the motion to dismiss was completed on November 6, 2020. A hearing on the motion to dismiss was held on February 17, 2021. 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 is scheduled to be held on December 8, 2021.

Some state dentistry 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

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

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 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.

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.

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 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 three and nine months ended September 30, 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 $10,500 for these matters, with the amount impacted by any interest and penalties associated with these matters and the amount, if any, of VAT the Company might subsequently recover from its customers.

Item 2. 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 condensed consolidated financial statements and related notes thereto included elsewhere in this Quarterly Report on Form 10-Q. In addition to historical condensed 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 Quarterly Report on Form 10-Q, and in our Annual Report on Form 10-K for the year ended December 31, 2020 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, New Zealand, United Kingdom, Ireland, Germany, Austria, the Netherlands, Mexico, Hong Kong, Singapore and Spain.

Key Business Metrics

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

Unique aligner order shipments

For the three months ended September 30, 2021 and 2020, we shipped 69,906 and 93,301 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 three months ended September 30, 2021 and 2020 was $1,900 and $1,794, 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. in our Annual Report on Form 10-K for the year ended December 31, 2020.

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. In response to COVID-19 and the related containment measures, we made the following operational changes beginning in the second quarter of 2020 to ensure the health and safety of our employees and our members: transitioned our employees, where possible, to a remote working environment; closed a portion of our SmileShops based on our real estate repositioning program, local public health guidelines and evolving customer behaviors and expectations; reconfigured our 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 our Smile Guides; reconfigured our 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 our manufacturing facilities. We also enacted a resilience policy that provides our 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, 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 by the HPS Credit Facility and further strengthened by a convertible notes offering in February 2021; and initiated a real estate repositioning program.

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 $29.1 million in the three and nine months ended September 30, 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 three and nine months ended September 30, 2021, we incurred one-time charges of approximately $1.5 million and $3.1 million, respectively, primarily associated with lease abandonment and store closure costs. Given the uncertain operating environment and the shift to work-from-home, we made the strategic decision to align our rent costs with the current needs of the business, while also ensuring that we have sufficient capacity to support future growth. 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 during 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, controlled growth and international expansion, 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.

Since the date of the Incident, we have been, and are, actively managing the Incident and, in consultation with its third-party advisors, investigating and seeking to understand and quantify the impact on us, our business operations and financial results. 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 third 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 third quarter of 2021, we remained strong on our member experience with referrals reaching 20% 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 professional network; expanding our presence in the teen demographic; and growing our business internationally. 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 expansion strategy.

International expansion

We will continue to make significant investments to expand our presence in international markets, particularly in Europe, Asia-Pacific and other geographies.

Pace of adoption for teledentistry

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

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 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 we believe will contribute to increased efficiencies going forward. 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.

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 (benefit)

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 8.

Adjusted EBITDA

To supplement our condensed 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 (benefit), 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 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.

Results of Operations

The following table summarizes our historical results of operations. The period-over-period comparison of results of operations is not necessarily indicative of results for future periods, and the results for any interim period are not necessarily indicative of the operating results to be expected for the full fiscal year. You should read this discussion of our results of

operations in conjunction with our condensed consolidated financial statements and related notes thereto included elsewhere in this Form 10-Q.

Comparison of the three and nine months ended September 30, 2021 and 2020

Revenues

Revenues decreased $30.8 million, or 18.3%, to $137.7 million in the three months ended September 30, 2021 from $168.5 million in the three months ended September 30, 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, partially offset by growth in our international markets.

Revenues increased $39.1 million, or 8.3%, to $511.3 million in the nine months ended September 30, 2021 from $472.2 million in the nine months ended September 30, 2020 primarily as a result of the more severe initial impact of the COVID-19 pandemic in that period and price increases enacted in late 2020.

For the three and nine months ended September 30, 2021, revenues for the U.S. and Canada were approximately $111.0 million and $422.8 million, or 80.6% and 82.7%, respectively, and revenues for the rest of world were approximately $26.7 million and $88.6 million, or 19.4% and 17.3%, respectively.

Cost of revenues

Cost of revenues decreased $10.3 million, or 20.8%, to $39.4 million in the three months ended September 30, 2021 from $49.8 million in the three months ended September 30, 2020. Cost of revenues decreased as a percentage of revenues from 29.5% in the three months ended September 30, 2020 to 28.6% in the three months ended September 30, 2021. The decrease in cost of revenues as a percentage of revenue is primarily due to continued automation of our manufacturing processes. The decrease in overall costs of revenues in the current year period as compared to the prior year period is primarily due to producing a lower number of aligners in the current year period.

Gross margin increased to 71.4% in the three months ended September 30, 2021 from 70.5% in the three months ended September 30, 2020, primarily as a result of the factors described above.

Cost of revenues decreased $25.1 million, or 15.8%, to $133.2 million in the nine months ended September 30, 2021 from $158.3 million in the nine months ended September 30, 2020, primarily as a result of the factors described above.

Marketing and selling expenses

Marketing and selling expenses were $96.2 million or 69.9% of revenue in the three months ended September 30, 2021 compared to $66.7 million or 39.6% of revenue in the three months ended September 30, 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 we continue to emerge to a more normal operating environment as compared to the prior year period which was impacted by cost containment measures implemented in response to the COVID-19 pandemic.

Marketing and selling expenses as a percentage of revenues increased to 56.6% in the nine months ended September 30, 2021 from 51.6% in the nine months ended September 30, 2020.

General and administrative expenses

General and administrative expenses increased $11.5 million, or 15.6%, to $85.7 million in the three months ended September 30, 2021 from $74.1 million in the three months ended September 30, 2020. The increase was primarily due to increases in personnel cost as a result of increased headcount and the absence of certain cost containment measures affecting the prior year period. As a percent of revenue, general and administrative expenses increased from 44.0% in the three months

ended September 30, 2020 to 62.2% in the three months ended September 30, 2021, primarily as a result of decreased revenue compared to the prior year period.

General and administrative expenses increased $18.0 million, or 7.7%, to $251.8 million in the nine months ended September 30, 2021 from $233.8 million in the nine months ended September 30, 2020.

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

Lease abandonment, impairment of long-lived assets and other related charges were $1.5 million and $3.1 million in the three and nine months ended September 30, 2021, respectively, compared to $5.7 million and $34.8 million in the three and nine months ended September 30, 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

Interest expense decreased $13.8 million, or 88.6%, to $1.8 million in the three months ended September 30, 2021 from $15.6 million in the three months ended September 30, 2020, primarily as a result of a change in our capital structure that significantly reduced our effective interest rate on our outstanding debt facilities.

Interest expense decreased $8.4 million to $21.3 million in the nine months ended September 30, 2021 from $29.6 million in the nine months ended September 30, 2020.

Loss on extinguishment of debt

Loss on extinguishment of debt in the three and nine months ended September 30, 2021 was $0.0 million and $47.6 million, respectively. The year to date 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 three and nine months ended September 30, 2020 was $0.0 million and $13.8 million, respectively, primarily made up of fees and unamortized costs associated with our previous JPM facility.

Other expense (income)

Other expense (income) was an expense of $2.7 million in the three months ended September 30, 2021 compared to income of $1.0 million in the three months ended September 30, 2020, primarily as a result of the impact of unrealized foreign currency translation adjustments.

Other expense increased $1.6 million to $3.7 million in the nine months ended September 30, 2021 from $2.1 million in the nine months ended September 30, 2020.

Provision for income tax expense (benefit)

Our provision for income tax benefit was $0.1 million and expense of $1.2 million for the three months ended September 30, 2021 and 2020.

Our provision for income tax expense was $1.6 million and $1.7 million for the nine months ended September 30, 2021 and 2020, respectively.

Adjusted EBITDA

For the three and nine months ended September 30, 2021, Adjusted EBITDA was negative $54.0 million and negative $71.6 million compared to a positive $3.0 million and negative $84.2 million for the three and nine months ended September 30, 2020. For the three months and nine months ended September 30, 2021, Adjusted EBITDA for the U.S. and Canada combined was a negative $33.5 million and negative $31.0 million, respectively, and Adjusted EBITDA for the rest of world for the three and nine months ended September 30, 2021 was negative $20.5 million and negative $40.6 million, respectively.

Liquidity and Capital Resources

As of September 30, 2021, SDC Inc. had cash on hand of $307.6 million, an accumulated deficit of $266.1 million and had working capital of $387.3 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, international expansion, 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.

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” included in our Annual Report on Form 10-K for the year ended December 31, 2020. We currently anticipate that such restrictions will not impact our ability to meet our cash obligations.

Comparison of the nine months ended September 30, 2021 and 2020

As of September 30, 2021, we had $307.6 million in cash, a decrease of $65.4 million compared to $373.0 million as of September 30, 2020.

Cash used in operating activities increased to $98.1 million during the nine months ended September 30, 2021 compared to $68.7 million in the nine months ended September 30, 2020, or an increase of $29.4 million, primarily due to changes in working capital including the timing of deferred revenue recognition.

Cash used in investing activities increased to $70.3 million during the nine months ended September 30, 2021, compared to $68.8 million in the nine months ended September 30, 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 to support our planned growth for both periods.

Cash provided by financing activities decreased to $158.8 million during the nine months ended September 30, 2021, compared to $192.0 million in the nine months ended September 30, 2020. Cash provided by financing activities during the nine months ended September 30, 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.

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 have been available to us. 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 to buy the final amount of 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.

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 9 to the condensed 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.”

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements during the periods presented.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations are based on our condensed consolidated financial statements, which we have prepared in accordance with GAAP. The preparation of condensed 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 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 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 condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q, we believe that the following accounting policy 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 condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q, 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.

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 returned. Accordingly, we are required to make estimates of expected returns and related refund liabilities. We estimate expected returns based upon our assessment of historical and expected cancellations.

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 59% 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

Prior to the IPO, we issued equity-based compensation awards to team members and non-team members through granting of incentive units. There have been no significant changes to this critical accounting policy which is disclosed in our Annual Report on Form 10-K for the year ended December 31, 2020.

Following the IPO, we have two types of equity-based compensation awards outstanding: Options and RSUs, including those issued pursuant to IBAs.

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 (benefit)

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 pay state income tax in certain jurisdictions, and the Company’s income tax provision in the condensed 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 condensed 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.

Recent Accounting Pronouncements

For a discussion of new accounting pronouncements recently adopted and not yet adopted, see Note 2 to our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest rate risk

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 to buy the final amount of 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.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our CEO and CFO, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on such evaluation, our CEO and CFO have concluded that as of September 30, 2021, our disclosure controls and procedures are designed at a reasonable assurance level and are effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure.

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 Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings

See Note 16 to our condensed consolidated financial statements included in Part 1, Item 1 of this Quarterly Report.

Item 1A. Risk Factors

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2020, as updated and supplemented below. However, the risks and uncertainties we face are not limited to those described in this report and in our Annual Report on Form 10-K. Additional risks and uncertainties not currently known to us or that we currently believe to be immaterial may also adversely affect our business, particularly given the rapidly evolving nature of the COVID-19 pandemic and containment measures, and the related impacts to economic and operating conditions.

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 has caused, and may continue to cause, 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.

2019 OMNIBUS EQUITY INCENTIVE PLAN
RESTRICTED STOCK AGREEMENT

Pursuant to your Restricted Stock Grant Notice (the “Grant Notice”) and this Restricted Stock Agreement (the “Agreement”), SmileDirectClub, Inc., a Delaware corporation (the “Company”), has granted you (the “Participant”), as of the Date of Grant set forth in the Grant Notice, a restricted stock award covering the number of shares set forth in the Grant Notice (the “Restricted Shares”) pursuant to the Company’s 2019 Omnibus Incentive Plan and any applicable sub-plan for a particular country (together, the “Plan”). Capitalized terms not explicitly defined in this Agreement or in the Grant Notice but defined in the Plan or in the Grant Notice shall have the meaning ascribed to them in the Plan or in the Grant Notice. In the event of any conflict between the terms of this Agreement and the Plan, the terms of the Plan will control.

1.Restrictions on Unvested Shares. While the Restricted Shares are unvested, Participant may not sell, transfer, pledge or assign (other than by will or by the laws of descent and distribution) the Restricted Shares. On and after the date of vesting, the Restricted Shares will become freely transferable (subject to Applicable Laws or additional restrictions imposed by the Company as permitted under the Plan).

2.Record of Shares. Unless the Company otherwise determines, the Company (or its transfer agent) will make an appropriate book entry representing the Restricted Shares until such time as the Restricted Shares vest.Upon the vesting of the Restricted Shares, the Company will transfer or release the Restricted Shares to the Participant in such manner as it deems appropriate, which may include making an appropriate book entry, removing any stop-transfer order or other restriction, as appropriate, transferring the vested Restricted Shares to a brokerage account or delivering to the Participant a stock certificate or stock certificates representing the shares.

3.Voting and Dividend Rights. At all times after the Grant Date, Participant may exercise full voting rights and will be credited with all dividends and other distributions paid with respect to the Restricted Shares, in each case so long as the Participant has not forfeited the Restricted Shares on or before the applicable record date; provided that any such dividends and other distributions will be held in the custody of the Company and will be subject to the same risk of forfeiture, restrictions on transferability and other terms of this award that apply to the Restricted Shares with respect to which such distributions were made. All such dividends or other distributions shall be paid to the Participant within 45 days following the date the Restricted Shares vest..

4.Termination. Except as otherwise provided in the Plan, any addenda to the Plan made pursuant to Section 4(d) of the Plan, or the Grant Notice, if Participant’s Continuous Service Status terminates at any time for any reason, all Restricted Shares for which vesting is no longer possible under the terms of the Grant Notice and this Agreement shall be forfeited to the Company on the date of such termination of Continuous Service Status, and all rights of Participant to such Restricted Shares shall immediately terminate at such time. Further, unless otherwise approved by the Company, Participant’s right to vest in the Restricted Shares will terminate as of the date of termination of the Participant’s Continuous Service Status and will not be extended by any contractual notice period or any period of “garden leave” or similar notice period mandated under employment laws in the jurisdiction where Participant is employed or the terms of Participant’s employment agreement, if any.

5.Responsibility for Taxes. As a condition to the grant and vesting of the Restricted Shares, Participant acknowledges that, regardless of any action taken by the Company or, if different, the Employer, the liability for all income tax, social security contributions (including employer’s social

3

security contributions to the extent such amounts may be lawfully recovered from the Participant), social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items (or any equivalent or similar taxes, contributions or other relevant tax-related items in any relevant jurisdiction) or required deductions, withholdings or payments legally applicable to him or her and related to the receipt or vesting of the Restricted Shares or subsequent sale of the Restricted Shares, or the participation in the Plan (“Tax-Related Items”) is and remains Participant’s sole responsibility and may exceed the amount actually withheld, if any, by the Company or the Employer. Participant further acknowledges and agrees that Participant is solely responsible for filing all relevant documentation that may be required in relation to the Restricted Shares or any Tax-Related Items (other than filings or documentation that is the specific obligation of the Company, its Parent, Subsidiaries or Affiliates (the “Company Group”) pursuant to Applicable Laws), such as, but not limited to, elections under Code Section 83(b), personal income tax returns or reporting statements in relation to the receipt or vesting of the Restricted Shares, the holding of Shares or any bank or brokerage account, the subsequent sale of Shares, and the receipt of any dividends.

Participant further acknowledges that the Company and/or the Employer: (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Restricted Shares, including, but not limited to, the receipt, vesting or sale of the Restricted Shares and the receipt of any dividends; and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Restricted Shares to reduce or eliminate Participant’s liability for Tax-Related Items or achieve any particular tax result. Participant also understands that Applicable Laws may require varying Share valuation methods for purposes of calculating Tax-Related Items, and the Company assumes no responsibility or liability in relation to any such valuation or for any calculation or reporting of income or Tax-Related Items that may be required of Participant under Applicable Laws.

Further, if Participant is subject to Tax-Related Items in more than one jurisdiction between the Date of Grant and the date of any relevant taxable or tax withholding event, as applicable, Participant acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Pursuant to this Agreement and subject to Applicable Laws, Participant authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy Participant’s Tax Withholding Obligations, if any, by (i) withholding from Participant’s wages or other compensation paid to Participant by the Company or the Employer, (ii) withholding from proceeds of the sale of Restricted Shares through a voluntary sale or through a mandatory sale arranged by the Company (on Participant’s behalf pursuant to this authorization) without further consent, (iii) withholding Shares that would otherwise vest or (iv) such other method as determined by the Company.

Depending on the method of satisfying the Tax Withholding Obligations, the Company may pay, withhold or account for such Tax Withholding Obligations by considering applicable minimum statutory withholding amounts or other applicable tax or withholding rates, including maximum applicable rates, in which case Participant will receive a refund of any over-withheld or over-paid amount in cash and will have no entitlement to the applicable Restricted Share.

Participant agrees to pay to the Company or the Employer any amount of Tax Withholding Obligations that the Company or the Employer may be required to pay, withhold or account for as a result of Participant’s receipt or vesting of the Restricted Shares or the participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to remove the restrictions on the Restricted Shares and/or forfeit the Restricted Shares if Participant fails to comply with his or her obligations in connection with the Tax Withholding Obligations.

4

Participant understands that Participant may suffer adverse tax consequences as a result of Participant’s receipt, vesting or the disposition of the Restricted Shares. Participant represents that Participant has consulted any tax consultants Participant deems advisable in connection with the receipt, vesting and/or the disposition of the Restricted Shares and that Participant is not relying on the Company (or the Employer) for any tax advice.

6.Nature of Grant. In accepting the Restricted Shares, Participant acknowledges, understands and agrees that:

(a) the Plan is established voluntarily by the Company, is discretionary in nature, and may be amended, suspended or terminated by the Company at any time, to the extent permitted by the Plan;

(b)the grant of the Restricted Shares is voluntary and occasional and does not create any contractual or other right to receive future grants of restricted stock or benefits in lieu of restricted stock, even if restricted stock has been granted in the past;

(c)all decisions with respect to future restricted stock grants or other grants, if any, will be at the sole discretion of the Company;

(d)Participant is voluntarily participating in the Plan;

(e)the Restricted Shares are not intended to replace any pension rights or compensation and are outside the scope of Participant’s service contract, if any;

(f)the Restricted Shares, and the income and value of same, are not part of normal or expected compensation for any purpose, including, without limitation, calculating any severance, resignation, termination, redundancy, dismissal, end-of- service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments;

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

(h)no entity in the Company Group shall be liable for any foreign exchange rate fluctuation between Participant’s local currency and the United States Dollar or the selection by the Company or any member of the Company Group in its sole discretion of an applicable foreign exchange rate that may affect the value of the Restricted Shares (or the calculation of income or Tax-Related Items thereunder) or of any amounts due to Participant pursuant to the sale of the Restricted Shares following vesting.

(i)no claim or entitlement to compensation or damages arises from forfeiture of the Restricted Shares or diminution in value of Restricted Shares and Participant irrevocably releases the Company and all Participating Companies from any such claim that may arise. If, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have arisen then, by signing this Agreement, Participant shall be deemed irrevocably to have waived Participant’s entitlement to pursue such a claim.

7.No Advice Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding Participant’s participation in the

5

Plan, or Participant’s receipt, vesting or the sale of such Restricted Shares. Participant is hereby advised to consult with his or her own personal tax, legal and financial advisors regarding his or her participation in the Plan and the Restricted Shares before accepting the Restricted Shares or otherwise taking any action related to the Restricted Shares or the Plan.

8.Data Privacy.

The following provisions shall only apply to Participant if he or she resides outside the European Economic Area:

(a)Participant voluntarily consents to the collection, use, disclosure and transfer to the United States and other jurisdictions, in electronic or other form, of his or her personal data as described in the Agreement and any other Award materials (“Data”) by and among, as applicable, the Company and any the Company, any Parents or Subsidiaries for the exclusive purpose of implementing, administering, and managing his or her participation in this Agreement.

(b)Participant understands that the Company and any Parents or Subsidiaries may collect, maintain, process and disclose, certain personal information about him or her, including, but not limited to, his or her name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any shares of stock or directorships held in the Company, details of all equity awards or any other entitlement to stock awarded, canceled, exercised, vested, unvested or outstanding in his or her favor, for the exclusive purpose of implementing, administering and, managing this Agreement.

(c)Participant understands that Data will be transferred to one or more service provider(s) selected by the Company, which may assist the Company with the implementation, administration and management of this Agreement. Participant understands that the recipients of the Data may be located in the United States or elsewhere, and that the recipient’s country (e.g., the United States) may have different, including less stringent, data privacy laws and protections than his or her country. Participant understands that if he or she resides outside the United States, he or she may request a list with the names and addresses of any potential recipients of the Data by contacting his or her local human resources representative. Participant authorizes the Company and any other possible recipients that may assist the Company (presently or in the future) with implementing, administering and managing this Agreement to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purposes of implementing, administering and managing his or her participation in this Agreement.

(d)Participant understands that Data will be held only as long as is necessary to implement, administer and manage his or her participation in this Agreement, including to maintain records regarding participation. Participant understands that if he or she resides in certain jurisdictions, to the extent required by applicable laws, he or she may, at any time, request access to Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents given by accepting these Awards, in any case without cost, by contacting in writing his or her local human resources representative. Further, Participant understands that he or she is providing these consents on a purely voluntary basis. If Participant does not consent or if he or she later seeks to revoke his or her consent, his or her engagement as a service provider with the Company or any Parents or Subsidiaries will not be adversely affected; the only consequence of refusing or withdrawing his or her consent is that the Company will not be able to grant him or her awards under this Agreement or administer or maintain awards. Therefore, Participant understands that refusing or withdrawing his or her consent may affect his or her ability to participate in this Agreement (including the right to retain the Awards). Participant understands that he or she may contact his or her local human

6

resources representative for more information on the consequences of his or her refusal to consent or withdrawal of consent.

9.Miscellaneous.

Participant also acknowledges that the Applicable Laws of the country in which Participant is residing or working at the time of grant, vesting or sale of the Restricted Shares (including any rules or regulations governing securities, foreign exchange, tax, labor, or other matters) may subject Participant to additional procedural or regulatory requirements that Participant is and will be solely responsible for and must fulfill.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Basis of Presentation

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 condensed consolidated financial statements (unaudited), 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, New Zealand, United Kingdom, Ireland, Germany, Austria, the Netherlands, Mexico, Hong Kong, Singapore and Spain.

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 condensed 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 accompanying interim condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the SEC and, in the opinion of management, reflect all normal recurring adjustments necessary for a fair presentation of results for the unaudited interim periods presented. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted. The results of operations for the interim period are not necessarily indicative of the results to be obtained for the full fiscal year. All intercompany balances and transactions are eliminated in consolidation.

The interim condensed 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 interim condensed 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 September 30, 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 condensed 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 $5,674 and $34,783 during the three and nine months ended September 30, 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 three and nine months ended September 30, 2021, we incurred one-time charges of approximately $1,473 and $3,137, respectively, 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.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Management Use of Estimates

The preparation of the interim condensed 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 interim condensed consolidated balance sheet using the Black-Scholes option pricing model (see Note 9). 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 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 and expected net collections, business and economic conditions, and other collection indicators. Management relies on the results of detailed reviews of historical write-offs and collections as a primary source of information in estimating the amount of contract consideration expected to be collected and implicit price concessions. 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 interim condensed 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:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Aligner revenue, net of implicit price concessions	$	108,273	$	139,279	$	418,590	$	388,111
Financing revenue, net of implicit price concessions	10,887		12,042		33,140		37,428
Retainers and other products revenue	18,523		17,180		59,595		46,685
Total revenue	$	137,683	$	168,501	$	511,325	$	472,224
Implicit price concessions included in total revenue	$	12,370	$	15,363	$	38,861	$	50,051

Deferred Revenue: Deferred revenue represents the Company’s contract liability for performance obligations associated with sales of aligners. During the nine months ended September 30, 2021 and 2020, the Company recognized $511,325 and $472,224 of revenue, respectively, of which $22,348, and $19,547 was previously included in deferred revenue on the condensed consolidated balance sheets as of December 31, 2020 and 2019, respectively.

Allowance for credit losses: The Company records a provision to maintain an allowance for credit losses that result from the failure or inability of its members or other partners to make required payments deemed collectible when the product was delivered. 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 of receivables was as follows:

	Accounts Receivable Allowance for Credit Losses
Balance at January 1, 2021	$	39,448
Current period provision for expected credit losses	38,102
Write-offs and other adjustments charged against the allowance, net of recoveries	(44,816)
Balance at September 30, 2021	$	32,734

Shipping and Handling Costs

Shipping and handling charges are recorded in cost of revenues in the condensed consolidated statements of operations upon shipment. The Company incurred approximately $4,901, $17,578, $5,891 and $18,516 in outsourced shipping expenses for the three and nine months ended September 30, 2021 and 2020, 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 three and nine months ended September 30, 2021 and 2020, the Company incurred marketing, selling, and advertising costs of $96,175, $289,241, $66,722, and $243,564, 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:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Cost of revenues	$	6,679	$	5,944	$	20,608	$	17,385
Marketing and selling expenses	1,340		1,635		4,384		4,906
General and administrative expenses	10,467		6,463		26,663		17,108
Total	$	18,486	$	14,042	$	51,655	$	39,399

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 9) as of September 30, 2021 and December 31, 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 September 30, 2021 the fair value of the debt facility was approximately $525,000 compared to its carrying value of $728,895.

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 September 30, 2021 or December 31, 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 September 30, 2021 or December 31, 2020, or net revenue for the three and nine months ended September 30, 2021 and 2020.

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 condensed 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. See “Recently Adopted Accounting Pronouncements—ASU No. 2016-02” below for more information. 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 condensed 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 condensed 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 condensed consolidated balance sheets and are amortized over a three-year period. During the three and nine months ended September 30, 2021 and 2020, the Company capitalized $4,135, $12,436, $3,555, and $10,938, respectively, of internally developed software costs. Amortization expense for internally developed software was $5,686, $12,433, $2,091, and $5,373 for the three and nine months ended September 30, 2021, and 2020, respectively.

Impairment

The Company evaluates long-lived assets (including finite-lived intangible assets) for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. An asset or asset group is considered impaired if its carrying amount exceeds the future undiscounted net cash flows that the asset or asset group is expected to 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 condensed 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 condensed 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 condensed 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 condensed consolidated financial statements when amounts become probable as to incurrence and estimable in amount.

Recently Adopted Accounting Pronouncements

In January 2021 the Company adopted FASB 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 condensed 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 interim 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 ChargesBeginning 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. As a result of these changes, the Company incurred one-time charges of $1,473 and $3,137 for the three and nine months ended September 30, 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:

Income Taxes

Income Taxes

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 condensed 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 (benefit) 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.

The income tax provision was as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Current:
Federal	$	362	$	186	$	682	$	186

Total income tax provision	$	(119)	$	1,190	$	1,576	$	1,745

At September 30, 2021 the Company had unused federal net operating loss carryforwards (tax effected) for federal income tax purposes of approximately $60,137, 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 $33,658, which expire from 2029 through 2035. The Company also had unused net operating loss carryforwards (tax effected) for foreign income tax purposes of approximately $4,260. 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 September 30, 2021, the Company maintained a valuation allowance of approximately $295,085 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.

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 three and nine months ended September 30, 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.

Total long-term debt	$	733,184	$	392,939

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 nine months ended September 30, 2021, the Company amortized under the effective interest rate method $2,732 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.

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 nine months ended September 30, 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 condensed consolidated statements of operations for the nine months ended September 30, 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 condensed 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 15, 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 condensed consolidated statement of operations. As of September 30, 2021, the Company has $0 outstanding under this promissory note.

Noncontrolling Interests	9 Months Ended

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 September 30, 2021, SDC Inc. had 119,103,923 shares of Class A common stock outstanding, which resulted in an equivalent amount of ownership of LLC Units by SDC Inc. As of September 30, 2021, SDC Inc. had a 30.6% 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 nine months ended September 30, 2021 and 2020. Prior to the IPO and Reorganization Transactions, SDC Inc. was not impacted by SDC Financial.

Incentive Compensation Plans

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 nine months ended September 30, 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		9.3	—
Exercised	—	—		—	—
Expired	—	—		—	—
Forfeited	—	—		—	—
Outstanding at September 30, 2021	1,729,339	$	22.69	8.0	$	—
Exercisable at September 30, 2021	597,816	$	23.00	7.9	$	—

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 nine months ended September 30, 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 pursuant to time-based vesting terms. As of September 30, 2021, unrecognized compensation expense related to the Options was $5,844. This expense is expected to be recognized over a weighted average period of 1.1 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	—	4,241,046	4,241,046	$	11.13

Forfeited	—	(136,548)	(136,548)	$	9.34
RSUs outstanding, September 30, 2021	223,581	5,176,783	5,400,364	$	12.72

As of September 30, 2021, unrecognized compensation expense related to unvested IBA and non-IBA RSUs was $46,673. This expense is expected to be recognized over a weighted average period of 2.5 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 $37,659 and $38,189 for the nine months ended September 30, 2021 and 2020, respectively. Amounts are included in general and administrative expense on the condensed consolidated statements of operations.

Earnings Per Share

Earnings Per Share [Abstract]

Earnings Per Share

Earnings 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 condensed consolidated financial statements.

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:

	Three Months Ended September 30,				Nine Months Ended September 30,

Earnings (loss) per share of Class A common stock outstanding - diluted	$	(0.23)	$	(0.11)	$	(0.62)	$	(0.64)

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:

	Three Months Ended September 30,		Nine Months Ended September 30,
	2021	2020	2021	2020
Options	1,729,339	1,679,339	1,729,339	1,679,339

Warrants	3,889,575	3,889,575	3,889,575	3,889,575
Shares issuable under the Notes (if converted method)(1)	41,389,822	—	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. 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 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 of the actions are in the preliminary stages. The Company denies any alleged wrongdoing and intends to vigorously defend against these actions. On March 31, 2021, the Plaintiffs filed an amended complaint. Defendants motion to dismiss the new complaint was filed on May 14, 2021 and was fully briefed as of July 19, 2021. The motion currently remains pending.

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 as of October 6, 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, the Defendants moved to dismiss or stay the entire action in favor of the related actions pending in Tennessee, which motion was granted and the case was dismissed on February 26, 2020. 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 is fully briefed and remains pending. 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.

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 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 consolidated complaint asserts claims against certain defendants for breaches of fiduciary duty, aiding and abetting those breaches, and unjust enrichment. The consolidated complaint seeks, among other things, disgorgement of allegedly unlawful profits from selling common stock and LLC Units. The Company has moved to dismiss the action. Briefing on the motion to dismiss was completed on November 6, 2020. A hearing on the motion to dismiss was held on February 17, 2021. 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 is scheduled to be held on December 8, 2021.

Some state dentistry 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 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.

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.

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 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 three and nine months ended September 30, 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 $10,500 for these matters, with the amount impacted by any interest and penalties associated with these matters and the amount, if any, of VAT the Company might subsequently recover from its customers.

Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2021

Accounting Policies [Abstract]

Basis of Presentation and Consolidation

Basis of Presentation and ConsolidationThe accompanying interim condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the SEC and, in the opinion of management, reflect all normal recurring adjustments necessary for a fair presentation of results for the unaudited interim periods presented. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted. The results of operations for the interim period are not necessarily indicative of the results to be obtained for the full fiscal year. All intercompany balances and transactions are eliminated in consolidation.

The interim condensed 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 interim condensed 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 September 30, 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 condensed 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 interim condensed 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 interim condensed consolidated balance sheet using the Black-Scholes option pricing model (see Note 9). 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 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 and expected net collections, business and economic conditions, and other collection indicators. Management relies on the results of detailed reviews of historical write-offs and collections as a primary source of information in estimating the amount of contract consideration expected to be collected and implicit price concessions. 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 interim condensed 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 condensed consolidated statements of operations upon shipment. The Company incurred approximately $4,901, $17,578, $5,891 and $18,516 in outsourced shipping expenses for the three and nine months ended September 30, 2021 and 2020, 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.

Allowance for credit losses

Allowance for credit losses: The Company records a provision to maintain an allowance for credit losses that result from the failure or inability of its members or other partners to make required payments deemed collectible when the product was delivered. 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.

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 September 30, 2021 or December 31, 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 September 30, 2021 or December 31, 2020, or net revenue for the three and nine months ended September 30, 2021 and 2020.

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 condensed 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. See “Recently Adopted Accounting Pronouncements—ASU No. 2016-02” below for more information. 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 condensed 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 condensed 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 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 condensed consolidated balance sheets and are amortized over a three-year period. During the three and nine months ended September 30, 2021 and 2020, the Company capitalized $4,135, $12,436, $3,555, and $10,938, respectively, of internally developed software costs. Amortization expense for internally developed software was $5,686, $12,433, $2,091, and $5,373 for the three and nine months ended September 30, 2021, and 2020, respectively.

Impairment

Impairment

The Company evaluates long-lived assets (including finite-lived intangible assets) for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. An asset or asset group is considered impaired if its carrying amount exceeds the future undiscounted net cash flows that the asset or asset group is expected to 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 condensed 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 condensed 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 condensed 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 condensed 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 FASB 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 condensed 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 interim 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.

	Three Months Ended September 30,		Nine Months Ended September 30,
	2021	2020	2021	2020
Options	1,729,339	1,679,339	1,729,339	1,679,339

(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.
