Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of American Well Corporation, its wholly-owned subsidiaries, those of professional corporations, which represent variable interest entities in which American Well has an interest and is the primary beneficiary (“PC”) (see Note 4) and National Telehealth Network (“NTN”), an entity in which American Well controls fifty percent or more of the voting shares (see Note 5). Intercompany accounts and transactions have been eliminated in consolidation. For consolidated entities where American Well owns or is exposed to less than 100% of the economics, the net income (loss) attributable to noncontrolling interests is recorded in the consolidated statements of operations and comprehensive loss equal to the percentage of the economic or ownership interest retained in each entity by the respective non-controlling party. The noncontrolling interests are presented as a separate component of stockholders’ deficit in the consolidated balance sheets. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reported periods. Significant estimates and assumptions reflected in these consolidated financial statements include, but are not limited to, revenue recognition, the estimated customer relationship period that is used in the amortization of deferred contract acquisition costs, the valuation of assets and liabilities acquired in business combinations, the useful lives of intangible assets, capitalization of software development costs and the valuation of share awards. The Company bases its estimates on historical experience, known trends, and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. On an ongoing basis, management evaluates its estimates, as there are changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results may differ from those estimates or assumptions. Due to the COVID-19 global pandemic, the global economy and financial markets have been disrupted and there is a significant amount of uncertainty about the length and severity of the consequences caused by the pandemic. The Company has considered information available to it as of the date of issuance of these financial statements and has not experienced any significant impact to its estimates and assumptions as a result of the COVID-19 pandemic. On an ongoing basis, the Company will continue to closely monitor the COVID-19 impact on its estimates and assumptions. Foreign Currency The Company’s reporting currency is the U.S. dollar. The Company determines the functional currency of each subsidiary based on the currency of the primary economic environment in which each subsidiary operates. Items included in the financial statements of such subsidiaries are measured using that functional currency. Foreign currency denominated monetary assets and liabilities are remeasured into U.S. dollars at current exchange rates and foreign currency denominated nonmonetary assets and liabilities are remeasured into U.S. dollars at historical exchange rates. Gains or losses from foreign currency remeasurement and settlements are included in interest income and other income (expense), net in the consolidated statements of operations and comprehensive loss. During the years ended December 31, 2022 and 2021, the Company’s gains (losses) from foreign currency remeasurement and settlement were $(377) and $445. During the year ended December 31, 2020, the Company’s gains or losses from foreign currency remeasurement and settlements were insignificant. Segment Information The Company’s chief operating decision makers (CODMs), its two Chief Executive Officers, review financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. The Company operates and manages its business as one reportable and operating segment. In addition, substantially all of the Company’s revenue and long-lived assets are attributable to operations in the United States for all periods presented. Variable Interest Entities The Company evaluates its ownership, contractual and other interests in entities to determine if it has any variable interest in a variable interest entity (“VIE”). These evaluations are complex and involve judgment. If the Company determines that an entity in which it holds a contractual or ownership interest is a VIE and that the Company is the primary beneficiary, the Company consolidates such entity in its consolidated financial statements. The primary beneficiary of a VIE is the party that meets both of the following criteria: (i) has the power to make decisions that most significantly affect the economic performance of the VIE; and (ii) has the obligation to absorb losses or the right to receive benefits that in either case could potentially be significant to the VIE. Management performs ongoing reassessments of whether changes in the facts and circumstances regarding the Company’s involvement with a VIE will cause the consolidation conclusion to change. Changes in consolidation status are applied prospectively. Concentrations of Credit Risk and Significant Clients Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, investments and accounts receivable. The Company invests its excess cash with large financial institutions that the Company believes are of high credit quality. Cash and cash equivalents are invested in highly rated money market funds. At times the Company’s cash balances with individual banking institutions are in excess of federally insured limits. The Company’s investments are invested in U.S. government agency bonds. The Company has not experienced any losses on its deposits of cash, cash equivalents or investments. The Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. The Company performs ongoing assessments and credit evaluations of its clients to assess the collectability of the accounts based on a number of factors, including past transaction experience, age of the accounts receivable, review of the invoicing terms of the contracts, and recent communication with clients. The Company has not experienced significant credit losses from its accounts receivable. As of December 31, 2022 two clients each accounted for 18% of outstanding accounts receivable and as of December 31, 2021 one client accounted for 19% of outstanding accounts receivable. For the years ended December 31, 2022, 2021 and 2020, sales to one client (which was a related party during the 2021 and 2020 period) represented 23%, 25% and 22% of the Company’s total revenue, respectively. Cash Equivalents The Company considers all highly liquid investments purchased with maturities of three months or less at the date of purchase to be cash equivalents. Restricted Cash As of December 31, 2022 and 2021, the Company maintained letters of credit totaling $795 and $795, respectively, for the benefit of the landlord of its leased property and performance surety bonds. The Company has classified $795 and $795 as non-current on its consolidated balance sheet as of December 31, 2022 and 2021, respectively. Investments The Company’s investments are classified as available-for-sale and are carried at fair value, with the unrealized gains and losses reported as a component of accumulated other comprehensive income (loss) in total stockholders’ equity (deficit). The Company has classified its available-for-sale investments as current assets on the consolidated balance sheet as these investments generally consist of highly marketable securities that are identified to be available to meet near-term cash requirements. Realized gains and losses and declines in value determined to be other than temporary are based on the specific identification method and are included as a component of interest income and other income (expense), net in the consolidated statements of operations and comprehensive loss. The Company periodically evaluates its investments for other-than-temporary impairment. When assessing investments for other-than-temporary declines in value, the Company considers such factors as, among other things, how significant the decline in value is as a percentage of the original cost, how long the market value of the investment has been less than its original cost, the Company’s ability and intent to retain investment for a period of time sufficient to allow for any anticipated recovery in fair value and market conditions in general. If any adjustment to fair value reflects a decline in the value of the investment that the Company considers to be “other than temporary,” the Company reduces the investment through a charge to the consolidated statement of operations and other comprehensive income (loss). No such adjustments were necessary during the periods presented. As of December 31, 2022 and 2021, there were no investments that had been in a continuous loss position for more than 12 months. Accounts Receivable, Net Accounts receivable primarily consist of amounts billed currently due from clients. Accounts receivable are presented net of an allowance for credit losses, which is an estimate of amounts that may not be collectible. In determining the amount of the allowance at each reporting date, the Company makes judgments about general economic conditions, historical write-off experience and any specific risks identified in client collection matters, including the aging of unpaid accounts receivable and changes in client financial conditions. Account balances are written off after all means of collection are exhausted and the potential for non-recovery is determined to be probable. Adjustments to the allowance for credit losses are recorded as general and administrative expenses in the consolidated statements of operations and comprehensive loss. Inventories The Company values all of its inventories, which consist primarily of raw material hardware components, at the lower of cost or net realizable value on a first-in, first-out basis (“FIFO”). Write-offs of potentially slow moving or damaged inventory are recorded through specific identification of obsolete or damaged material. Property and Equipment Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization are recognized using the straight-line method over the useful life of the assets. Computer equipment is depreciated over three to four years. Computer software, furniture and fixtures and office equipment are depreciated over three years. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life of the related asset. Repairs and maintenance costs are expensed as incurred. When assets are sold or retired, the cost and related accumulated depreciation or amortization are removed from the accounts, with any resulting gain or loss recorded in the consolidated statements of operations and comprehensive loss. Business Combinations The Company accounts for business combinations using the acquisition method of accounting. Application of this method of accounting requires that (i) identifiable assets acquired (including identifiable intangible assets) and liabilities assumed generally be measured and recognized at fair value as of the acquisition date and (ii) the excess of the purchase price over the net fair value of identifiable assets acquired and liabilities assumed be recognized as goodwill. Transaction costs related to business combinations are expensed as incurred in general and administrative expense in the consolidated statement of operations and comprehensive loss. Determining the fair value of assets acquired and liabilities assumed, and the allocation of the purchase price requires management to use judgment and estimates with regards to the selection of valuation methodologies, especially with respect to intangible assets. Critical estimates in valuing certain identifiable assets include, but are not limited to, significant assumptions related to estimates of future revenue and cash flows, expected long-term market growth, expected revenue growth rates, future expected operating expenses, earnings before interest, taxes, depreciation and amortization margin, and discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, the Company may record certain adjustments to the carrying value of the assets acquired and liabilities assumed with the corresponding offset to goodwill. After the measurement period, which could last up to one year after the transaction date, all adjustments are recorded in the consolidated statements of operations and comprehensive loss. Goodwill The Company recognizes the excess of the purchase price over the fair value of identifiable net assets acquired as goodwill. Goodwill is not amortized but is tested for impairment annually on November 30 or more frequently if events or changes in circumstances indicate that the carrying amount of the goodwill may not be recoverable. The Company operates as a single operating segment with one reporting unit and consequently evaluates goodwill for impairment based on an evaluation of the fair value of the Company as a whole. In the fair value determination the Company looks first at market capitalization and also considers assumptions such as control premium, market data and expected future cash flows, as needed. An impairment charge is recognized for the excess of the carrying value of goodwill over its implied the fair value. The Company’s annual goodwill impairment test resulted in no impairment charges in any of the periods in the consolidated financial statements. Intangible Assets Intangible assets acquired in a business combination are recognized at fair value using generally accepted valuation methods deemed appropriate for the type of intangible asset acquired and reported net of accumulated amortization, separately from goodwill. Finite-lived intangible assets, which primarily consist of customer relationships, contractor relationships, technology and trade name, are stated at historical cost and amortized over the assets’ estimated useful lives. Impairment of Long-Lived Assets Long-lived assets consist primarily of property and equipment and intangible assets. Long-lived assets to be held and used are tested for recoverability whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. Factors that the Company considers in deciding when to perform an impairment review include significant underperformance of the business in relation to expectations, significant negative industry or economic trends and significant changes or planned changes in the use of the assets, among others. When testing for asset impairment, the Company groups assets and liabilities at the lowest level for which cash flows are separately identifiable. If an impairment review is performed to evaluate a long-lived asset group for recoverability, the Company compares forecasts of undiscounted cash flows expected to result from the use and eventual disposition of the long-lived asset group to its carrying value. An impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of an asset group are less than the asset’s carrying amount. The impairment loss would be based on the excess of the carrying value of the impaired asset group over its fair value. To date, the Company has not recorded any impairment losses on long-lived assets. No events or changes in circumstances existed to require an impairment assessment during the years ended December 31, 2022 and 2021. Investment in Minority Owned Joint Venture The Company and Cleveland Clinic partnered to form a joint venture, under the name CCAW, JV LLC, to provide broad access to comprehensive and high acuity care services via digital care. The Company does not have a controlling financial interest in CCAW, JV LLC, but it does have the ability to exercise significant influence over the operating and financial policies of CCAW, JV LLC. Therefore, the Company accounts for its investment in CCAW, JV LLC using the equity method of accounting. The joint venture is considered a variable interest entity under ASC 810-10, but the Company is not the primary beneficiary as it does not have the power to direct the activities of the joint venture that most significantly impact its performance. The Company’s evaluation of ability to impact performance is based on Cleveland Clinic’s managing directors and Cleveland Clinic’s ability to appoint and remove the chairperson who has the ability to cast the tie breaking vote on the most significant activities. During the year ended December 31, 2020, the Company contributed $2,940 as its initial investment for a 49% interest in CCAW, JV LLC. The agreement also requires aggregate total capital contributions by the Company up to an additional $11,800 in two phases, which is yet to be defined. During the years ended December 31, 2022 and 2021 the Company made a capital contribution of $1,960 and $2,548 related to a portion of the phase one capital commitment. For the year ended December 31, 2022 and 2021, the Company recognized a loss of $2,278 and $3,132 as its proportionate share of the joint ventures results of operations, respectively. Accordingly, the carrying value of the equity method investment as of December 31, 2022 and 2021 was $(150) and $168, respectively. As the share of losses exceeds the carrying amount of the investment, the carrying amount as of December 31, 2022 it is included in the balance of accrued expenses and other current liabilities on the consolidated balance sheet. Advertising Costs Advertising costs are expensed as incurred and are included in sales and marketing expense in the consolidated statement of operations and comprehensive loss. For the years ended December 31, 2022, 2021 and 2020, the Company’s advertising expenses were $6,607, $5,604 and $3,860, respectively. Research and Development Costs Research and development costs are expensed as incurred. Research and development expenses include payroll, employee benefits and other expenses associated with product development. Internal-Use Software The Company evaluates development costs incurred to develop functionality in connection with its internal-use software for capitalization. Qualifying costs incurred to develop internal-use software are capitalized when (i) the preliminary project stage is completed, (ii) management has authorized further funding for the completion of the project and (iii) it is probable that the project will be completed and performed as intended. Capitalization of these costs ceases once the project is substantially complete and the software is ready for its intended purpose. Capitalized internal-use software costs are included in intangible assets on the consolidated balance sheet for the year ended December 31, 2022 and these costs were not material to the Company’s consolidated financial statements during the year ended December 31, 2021. There were no impairment charges related to capitalized software development costs during 2022. Capitalized software development costs are amortized using the straight-line method over an estimated useful life of three years. Stock-Based Compensation The Company measures all stock options and other stock-based awards granted to employees and directors based on the fair value on the date of the grant and recognizes compensation expense of those awards, net of estimated forfeitures, over the requisite service period, which is generally the vesting period of the respective award. Generally, the Company issues stock options, restricted stock units (“RSU’s”) and performance-based market condition share awards ("PSU's") to employees. Stock options and RSUs only have service-based vesting conditions and the Company records the expense for these awards using the straight-line method. Stock option awards and restricted stock units issued to the co-CEOs prior to the IPO or as a result of the IPO (“IPO RSUs”) were expensed when granted as the requisite future service of the awards is not substantive for accounting purposes. PSUs have multiple tranches each with certain market capitalization milestones and service-based vesting conditions and the Company records the expense for these awards over the estimated life of each tranche. The Company classifies stock-based compensation expense in its consolidated statements of operations and comprehensive loss in the same manner in which the award’s recipient’s payroll costs are classified. The Company recognizes compensation expense for only the portion of awards that are expected to vest. In developing a forfeiture rate estimate, the Company has considered its historical experience to estimate pre-vesting forfeitures for service-based awards. The impact of a forfeiture rate adjustment will be recognized in full in the period of adjustment, and if the actual forfeiture rate is materially different from the Company’s estimate, the Company may be required to record adjustments to stock-based compensation expense in future periods. The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model. The restricted stock units issued to the co-CEOs as a result of the IPO had the fair value estimated using a binomial lattice approach. The Company historically had been a private company and lacks company-specific historical and implied volatility information. Therefore, it estimates its expected stock volatility based on the historical volatility of a publicly traded set of peer companies and expects to continue to do so until such time as it has adequate historical data regarding the volatility of its own traded stock price. The expected term of the Company’s stock options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. The expected dividend yield is based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future. The fair value of the PSUs is estimated using a Monte-Carlo valuation simulation. Similar to stock options, the Company estimates its expected stock volatility based on the historical volatility of a publicly traded set of peer companies and expects to continue to do so until such time as it has adequate historical data regarding the volatility of its own traded stock price. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. The expected dividend yield is based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future. Deferred Contract Acquisition Costs The Company capitalizes sales commissions and certain parts of the Company bonus that are incremental to the acquisition of client contracts. These costs are recorded as deferred contract acquisition costs on the consolidated balance sheets. The Company determines whether costs should be deferred based on its sales compensation plans if the commissions are in fact incremental and would not have occurred absent the client contract. Sales commissions are paid upon the initial acquisition of a contract and are amortized over an estimated period of benefit of five years. Amortization is recognized on a straight-line basis commensurate with the pattern of revenue recognition. The Company determined the period of benefit for commissions paid for the acquisition of initial contracts by taking into consideration the commitment term of the client contract, the nature of the Company’s technology development life cycle, and an estimated client relationship period. Amortization of deferred contract acquisition costs is included in sales and marketing expenses in the accompanying consolidated statements of operations and comprehensive loss. The Company reviews these deferred costs to determine whether events or changes in circumstances have occurred that could impact the period of benefit of these deferred contract acquisition costs. There were no impairment losses recorded during the periods presented. Deferred Contract Fulfillment Costs The Company capitalizes costs to fulfill contracts with clients in “Prepaid expenses and other current assets” and “Other assets” on its consolidated balance sheet. The Company amortizes these costs to cost of revenue in the consolidated statement of operations and comprehensive loss consistent with the revenue recognition of the performance obligations in the associated contracts. The Company assesses these costs for impairment at the end of each reporting period. There were no impairment losses recorded during the periods presented. Comprehensive Loss Comprehensive loss includes net loss as well as other changes in stockholders’ equity (deficit) that result from transactions and economic events other than those with stockholders. Income Taxes The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the financial statements or in the Company’s tax returns. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using the enacted tax rates in effect for the year in which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income, and to the extent it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established through a charge to income tax expense. The potential for recovery of deferred tax assets is evaluated by considering taxable income in carryback years, existing taxable temporary differences, prudent and feasible tax planning strategies and estimating the future taxable profits. The Company accounts for uncertainty in income taxes recognized in the financial statements by applying a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The provision for income taxes includes the effects of any resulting tax reserves, or unrecognized tax benefits, that are considered appropriate as well as the related net interest and penalties. Net Loss per Share The Company follows the two-class method when computing net loss per share as the Company has issued shares that meet the definition of participating securities. The two-class method determines net loss per share for each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires income or loss available to common stockholders for the period to be allocated between common and participating securities based upon their respective rights to receive dividends as if all income or losses for the period had been distributed. Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding for the period. Diluted net loss attributable to common stockholders is computed by adjusting net losses attributable to common stockholders to reallocate undistributed earnings based on the potential impact of dilutive securities. Diluted net loss per share attributable to common stockholders is computed by dividing the diluted net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding for the period, including potential dilutive common shares. The Company’s convertible preferred stock contractually entitles the holders of such shares to participate in dividends, but contractually does not require the holders of such shares to participate in losses of the Company. Accordingly, in periods in which the Company reports a net loss attributable to common stockholders, diluted net loss per share attributable to common stockholders is the same as basic net loss per share attributable to common stockholders since dilutive common shares are not assumed to have been issued, as their effect is anti-dilutive. The Company reported a net loss attributable to common stockholders for the years ended December 31, 2022, 2021 and 2020. Revenue Recognition Platform subscription The Company generates revenue primarily from contracts with clients who purchase subscriptions to access the Company’s enterprise software which includes access to the Company’s affiliated medical group. The Company’s clients do not have the right to take possession of the Company’s software operating its digital care platform at any time. Instead, clients are granted access to the Company’s platform over the contractual period. Access to the platform, including the stand ready obligation to provide access to the affiliated medical group, represents a series of distinct services as the Company continually provides access to and fulfills its obligation to the client over the contract term. The typical contract term is three years. Most of the Company’s contracts are non-cancelable over the contractual term. Clients typically have the right to terminate their contracts for cause if the Company fails to perform in accordance with the contractual terms. For clients who purchase access to the enterprise digital care platform (the “Amwell Platform”), the Company hosts a dedicated instance of the Amwell Platform, white-labeled under the client’s own name, branding, and with customized workflows and operating choices. The implementation services for the Amwell Platform are not distinct within the context of the contract because the Company’s promise to perform the implementation services are not separately identifiable from the access to the Amwell Platform. The implementation services, which customize the client’s Amwell Platform, are integral to the client’s ability to derive its intended benefit from the Amwell Platform. The development and implementation services generally span several months and cannot be performed by another entity. Therefore, access to the Amwell Platform and the implementation services are bundled together and represent a single performance obligation. The fixed consideration related to the single performance obligation is generally recognized on a straight-line basis over the contract term beginning on the date access to the Amwell Platform is provided. The Company uses a time-elapsed method to measure progress because the Company transfers control evenly over the contractual period. Clients can also purchase access to the Company’s co-branded digital care practice hosted on the Company’s shared services platform (the “Amwell Practice”). The implementation services for the Amwell Practice do not significantly modify or customize the Amwell Practice, typically occur over a few days, and can be performed by other entities. Therefore, access to the Amwell Practice and the implementation services are separate outputs promised by the Company and represent two distinct performance obligations. Clients may be billed prior to the related goods or services being transferred to the client. In determining the transaction price, the Company adjusts the promised amount of consideration for a significant financing component if the timing of payments agreed to by the parties in the contract provide the client a significant benefit of financing. The Company has applied the practical expedient and recognizes the promised amount of consideration without adjusting for the effects of a significant financing component if the Company expects, at contract inception, that the period between the transfer of goods or services to the client when the client pays for that good or service will be one year or less. As of December 31, 2022, the effect of the financing component is not significant and does not materially change the amount of revenue that would be recognized under a contract. The total fixed consideration is allocated to each distinct performance obligation based on standalone selling price (“SSP”) which reflects the amount that the Company charges for each performance obligation if it was sold separately in a standalone sale. The fixed consideration to access the Amwell Practice is recognized on a straight-line basis over the contract term beginning on the date access to the Amwell Practice is provided. A time-elapsed method is used to measure progress because the Company transfers control evenly over the contractual period. The fixed consideration related to the implementation services is recognized as the services are performed. In addition to the fixed consideration received from the Amwell Platform and Amwell Practice, the Company can also receive variable consideration based on the number of members serviced (that is, a stated fee per member per month). The Company allocates the per member per month variable consideration to the month that the fee is earned, correlating with the amount of services it is providing, which is consistent with the allocation objective of the series guidance. Revenue recognized from the per member per month variable consideration does not represent a significant portion of total revenue for the years ended December 31, 2022, 2021 and 2020. Some contracts with clients contain a renewal option which allows the client to continue access to the Amwell Platform for a stated price after the initial contractual term has ended. These renewal options are evaluated on a case-by-case basis but generally do not provide a material right as they are priced at or above the price for the same service that the Company offers to similar clients and, as such, would not result in a separate performance obligation. Visits The Company also generates revenue when either the Amwell Platform or the Amwell Practice is utilized to conduct a medical visit. In the event of a visit, the fee that is earned upon completion of the visit is allocated to the specific day of performance, as the visit fee meets the criteria to allocate variable consideration to a distinct service within a series of distinct services that comprise the single performance obligation. Therefore, visit fees are recognized when the visits are completed, and the Company has delivered on its stand-ready obligation to provide access to the medical professional. In addition, clients can visit with the Company’s affiliated medical group without purchasing access to an Amwell Platform or Amwell Practice. These direct-to-consumer virtual care visits are available through the Company’s website where clients can conduct a visit with the Company’s affiliated medical group for a fixed fee. The Company’s affiliated medical group is responsible for fulfilling the promise to the client to perform the medical visit. The Company has discretion in establishing the price for the visit, is responsible for the resolution of any client issues, and is exposed to credit risk for the receivable due from the client. Therefore, the Company recognizes the visit fee on a gross basis upon completion of the visit. Other Other revenue primarily represents professional services associated with the Amwell Platform. After implementation of Amwell Platform has been completed, some clients purchase other professional services, which are designed to help clients enhance their ability to use Amwell Platform. For the majority of arrangements, the Company prices these professional services on a time and material basis, has standalone selling price for these services, and recognizes revenue as services are performed. Other revenue also includes sale of hardware products, such as the Company’s digital care carts and kiosks. Revenue from the sale of hardware products to clients is recognized upon the transfer of control, which occurs upon shipment of the product. Deferred Revenue Deferred revenue includes amounts collected or billed in excess of revenue recognized. Deferred revenue is recognized as revenue as the related performance obligations are satisfied. Deferred revenue that will be recognized during the succeeding twelve-month period is recorded as a current liability and the remaining portion is recorded as a noncurrent liability on the consolidated balance sheet. Leases The Company determines at the inception of a contract if such arrangement is or contains a lease. A contract is or contains a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The Company classifies leases at the lease commencement date as operating or finance leases and records a right-of-use asset and a lease liability on the consolidated balance sheet for all leases with an initial lease term of greater than 12 months. Leases with an initial term of 12 months or less are not recorded on the balance sheet, but payments are recognized as expense on a straight-line basis over the lease term. The Company’s contracts may contain both lease and non-lease components. Non-lease components may include maintenance, utilities, and other operating costs. The Company combines the lease and non-lease components of fixed costs in its lease arrangements as a single lease component. Variable costs, such as utilities or maintenance costs, are not included in the measurement of right-of-use assets and lease liabilities, but rather are expensed when the event determining the amount of variable consideration to be paid occurs. Lease liabilities and their corresponding right-of-use assets are recorded based on the present value of future lease payments over the expected lease term. The Company determines the present value of future lease payments by using its estimated secured incremental borrowing rate for that lease term as the interest rate implicit in the lease is not readily determinable. The Company estimates its secured incremental borrowing rate for each lease based on the rate of interest that the Company would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term. Certain of the Company’s leases include options to extend or terminate the lease. The amounts determined for the Company’s right-of-use assets and lease liabilities generally do not assume that renewal options or early-termination provisions, if any, are exercised, unless it is reasonably certain that the Company will exercise such options. Recently Issued and Adopted Accounting Pronouncements In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which simplifies the accounting for income taxes by removing certain exceptions and clarifying and amending existing guidance. The guidance was adopted effective January 1, 2021 and did not have a material impact on the consolidated financial statements. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”), which requires that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. To achieve this, an acquirer may assess how the acquiree applied Topic 606 to determine what to record for the acquired revenue contracts. Generally, this should result in an acquirer recognizing and measuring the acquired contract assets and contract liabilities consistent with how they were recognized and measured in the acquiree’s financial statements. The guidance was adopted effective July 1, 2021 and impacted the accounting of acquired deferred revenue for the Conversa and SilverCloud acquisitions that occurred in August 2021. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model. It also eliminates the concept of other-than-temporary impairment and requires credit losses related to available-for-sale debt securities to be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. These changes may result in earlier recognition of credit losses. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, which narrowed the scope and changed the effective date for non-public entities for ASU 2016-13. The FASB subsequently issued supplemental guidance within ASU No. 2019-05, Financial Instruments—Credit Losses (Topic 326): Targeted Transition Relief (“ASU 2019-05”). ASU 2019-05 provides an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis. The Company adopted ASU 2016-13 and the related clarifications in 2021. The adoption did not have a material effect on the Company’s consolidated financial statements.

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of American Well Corporation, its wholly-owned subsidiaries, those of professional corporations, which represent variable interest entities in which American Well has an interest and is the primary beneficiary (“PC”) (see Note 4) and National Telehealth Network (“NTN”), an entity in which American Well controls fifty percent or more of the voting shares (see Note 5). Intercompany accounts and transactions have been eliminated in consolidation.

For consolidated entities where American Well owns or is exposed to less than 100% of the economics, the net income (loss) attributable to noncontrolling interests is recorded in the consolidated statements of operations and comprehensive loss equal to the percentage of the economic or ownership interest retained in each entity by the respective non-controlling party. The noncontrolling interests are presented as a separate component of stockholders’ deficit in the consolidated balance sheets.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reported periods. Significant estimates and assumptions reflected in these consolidated financial statements include, but are not limited to, revenue recognition, the estimated customer relationship period that is used in the amortization of deferred contract acquisition costs, the valuation of assets and liabilities acquired in business combinations, the useful lives of intangible assets, capitalization of software development costs and the valuation of share awards. The Company bases its estimates on historical experience, known trends, and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. On an ongoing basis, management evaluates its estimates, as there are changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results may differ from those estimates or assumptions.

Due to the COVID-19 global pandemic, the global economy and financial markets have been disrupted and there is a significant amount of uncertainty about the length and severity of the consequences caused by the pandemic. The Company has considered information available to it as of the date of issuance of these financial statements and has not experienced any significant impact to its estimates and assumptions as a result of the COVID-19 pandemic. On an ongoing basis, the Company will continue to closely monitor the COVID-19 impact on its estimates and assumptions.

Foreign Currency

The Company’s reporting currency is the U.S. dollar. The Company determines the functional currency of each subsidiary based on the currency of the primary economic environment in which each subsidiary operates. Items included in the financial statements of such subsidiaries are measured using that functional currency.

Foreign currency denominated monetary assets and liabilities are remeasured into U.S. dollars at current exchange rates and foreign currency denominated nonmonetary assets and liabilities are remeasured into U.S. dollars at historical exchange rates. Gains or losses from foreign currency remeasurement and settlements are included in interest income and other income (expense), net in the consolidated statements of operations and comprehensive loss. During the years ended December 31, 2022 and 2021, the Company’s gains (losses) from foreign currency remeasurement and settlement were $(377) and $445. During the year ended December 31, 2020, the Company’s gains or losses from foreign currency remeasurement and settlements were insignificant.

Segment Information

The Company’s chief operating decision makers (CODMs), its two Chief Executive Officers, review financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. The Company operates and manages its business as one reportable and operating segment. In addition, substantially all of the Company’s revenue and long-lived assets are attributable to operations in the United States for all periods presented.

Variable Interest Entities

The Company evaluates its ownership, contractual and other interests in entities to determine if it has any variable interest in a variable interest entity (“VIE”). These evaluations are complex and involve judgment. If the Company determines that an entity in which it holds a contractual or ownership interest is a VIE and that the Company is the primary beneficiary, the Company consolidates such entity in its consolidated financial statements. The primary beneficiary of a VIE is the party that meets both of the following criteria: (i) has the power to make decisions that most significantly affect the economic performance of the VIE; and (ii) has the obligation to absorb losses or the right to receive benefits that in either case could potentially be significant to the VIE. Management performs ongoing reassessments of whether changes in the facts and circumstances regarding the Company’s involvement with a VIE will cause the consolidation conclusion to change. Changes in consolidation status are applied prospectively.

Concentrations of Credit Risk and Significant Clients

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, investments and accounts receivable. The Company invests its excess cash with large financial institutions that the Company believes are of high credit quality. Cash and cash equivalents are invested in highly rated money market funds. At times the Company’s cash balances with individual banking institutions are in excess of federally insured limits. The Company’s investments are invested in U.S. government agency bonds. The Company has not experienced any losses on its deposits of cash, cash equivalents or investments. The Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships.

The Company performs ongoing assessments and credit evaluations of its clients to assess the collectability of the accounts based on a number of factors, including past transaction experience, age of the accounts receivable, review of the invoicing terms of the contracts, and recent communication with clients. The Company has not experienced significant credit losses from its accounts receivable.

As of December 31, 2022 two clients each accounted for 18% of outstanding accounts receivable and as of December 31, 2021 one client accounted for 19% of outstanding accounts receivable. For the years ended December 31, 2022, 2021 and 2020, sales to one client (which was a related party during the 2021 and 2020 period) represented 23%, 25% and 22% of the Company’s total revenue, respectively.

Cash Equivalents

The Company considers all highly liquid investments purchased with maturities of three months or less at the date of purchase to be cash equivalents.

Restricted Cash

As of December 31, 2022 and 2021, the Company maintained letters of credit totaling $795 and $795, respectively, for the benefit of the landlord of its leased property and performance surety bonds. The Company has classified $795 and $795 as non-current on its consolidated balance sheet as of December 31, 2022 and 2021, respectively.

Investments

The Company’s investments are classified as available-for-sale and are carried at fair value, with the unrealized gains and losses reported as a component of accumulated other comprehensive income (loss) in total stockholders’ equity (deficit). The Company has classified its available-for-sale investments as current assets on the consolidated balance sheet as these investments generally consist of highly marketable securities that are identified to be available to meet near-term cash requirements.

Realized gains and losses and declines in value determined to be other than temporary are based on the specific identification method and are included as a component of interest income and other income (expense), net in the consolidated statements of operations and comprehensive loss.

The Company periodically evaluates its investments for other-than-temporary impairment. When assessing investments for other-than-temporary declines in value, the Company considers such factors as, among other things, how significant the decline in value is as a percentage of the original cost, how long the market value of the investment has been less than its

original cost, the Company’s ability and intent to retain investment for a period of time sufficient to allow for any anticipated recovery in fair value and market conditions in general. If any adjustment to fair value reflects a decline in the value of the investment that the Company considers to be “other than temporary,” the Company reduces the investment through a charge to the consolidated statement of operations and other comprehensive income (loss). No such adjustments were necessary during the periods presented.

As of December 31, 2022 and 2021, there were no investments that had been in a continuous loss position for more than 12 months.

Accounts Receivable, Net

Accounts receivable primarily consist of amounts billed currently due from clients. Accounts receivable are presented net of an allowance for credit losses, which is an estimate of amounts that may not be collectible. In determining the amount of the allowance at each reporting date, the Company makes judgments about general economic conditions, historical write-off experience and any specific risks identified in client collection matters, including the aging of unpaid accounts receivable and changes in client financial conditions. Account balances are written off after all means of collection are exhausted and the potential for non-recovery is determined to be probable. Adjustments to the allowance for credit losses are recorded as general and administrative expenses in the consolidated statements of operations and comprehensive loss.

Inventories

The Company values all of its inventories, which consist primarily of raw material hardware components, at the lower of cost or net realizable value on a first-in, first-out basis (“FIFO”). Write-offs of potentially slow moving or damaged inventory are recorded through specific identification of obsolete or damaged material.

Property and Equipment

Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization are recognized using the straight-line method over the useful life of the assets. Computer equipment is depreciated over three to four years. Computer software, furniture and fixtures and office equipment are depreciated over three years. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life of the related asset. Repairs and maintenance costs are expensed as incurred. When assets are sold or retired, the cost and related accumulated depreciation or amortization are removed from the accounts, with any resulting gain or loss recorded in the consolidated statements of operations and comprehensive loss.

Business Combinations

The Company accounts for business combinations using the acquisition method of accounting. Application of this method of accounting requires that (i) identifiable assets acquired (including identifiable intangible assets) and liabilities assumed generally be measured and recognized at fair value as of the acquisition date and (ii) the excess of the purchase price over the net fair value of identifiable assets acquired and liabilities assumed be recognized as goodwill. Transaction costs related to business combinations are expensed as incurred in general and administrative expense in the consolidated statement of operations and comprehensive loss.

Determining the fair value of assets acquired and liabilities assumed, and the allocation of the purchase price requires management to use judgment and estimates with regards to the selection of valuation methodologies, especially with respect to intangible assets. Critical estimates in valuing certain identifiable assets include, but are not limited to, significant assumptions related to estimates of future revenue and cash flows, expected long-term market growth, expected revenue growth rates, future expected operating expenses, earnings before interest, taxes, depreciation and amortization margin, and discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, the Company may record certain adjustments to the carrying value of the assets acquired and liabilities assumed with the corresponding offset to goodwill. After the measurement period, which could last up to one year after the transaction date, all adjustments are recorded in the consolidated statements of operations and comprehensive loss.

Goodwill

The Company recognizes the excess of the purchase price over the fair value of identifiable net assets acquired as goodwill. Goodwill is not amortized but is tested for impairment annually on November 30 or more frequently if events or changes in circumstances indicate that the carrying amount of the goodwill may not be recoverable. The Company operates as a single operating segment with one reporting unit and consequently evaluates goodwill for impairment based on an evaluation of the fair value of the Company as a whole. In the fair value determination the Company looks first at market capitalization and also considers assumptions such as control premium, market data and expected future cash flows, as needed. An impairment charge is recognized for the excess of the carrying value of goodwill over its implied the fair value. The Company’s annual goodwill impairment test resulted in no impairment charges in any of the periods in the consolidated financial statements.

Intangible Assets

Intangible assets acquired in a business combination are recognized at fair value using generally accepted valuation methods deemed appropriate for the type of intangible asset acquired and reported net of accumulated amortization, separately from goodwill. Finite-lived intangible assets, which primarily consist of customer relationships, contractor relationships, technology and trade name, are stated at historical cost and amortized over the assets’ estimated useful lives.

Impairment of Long-Lived Assets

Long-lived assets consist primarily of property and equipment and intangible assets. Long-lived assets to be held and used are tested for recoverability whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. Factors that the Company considers in deciding when to perform an impairment review include significant underperformance of the business in relation to expectations, significant negative industry or economic trends and significant changes or planned changes in the use of the assets, among others. When testing for asset impairment, the Company groups assets and liabilities at the lowest level for which cash flows are separately identifiable. If an impairment review is performed to evaluate a long-lived asset group for recoverability, the Company compares forecasts of undiscounted cash flows expected to result from the use and eventual disposition of the long-lived asset group to its carrying value. An impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of an asset group are less than the asset’s carrying amount. The impairment loss would be based on the excess of the carrying value of the impaired asset group over its fair value. To date, the Company has not recorded any impairment losses on long-lived assets. No events or changes in circumstances existed to require an impairment assessment during the years ended December 31, 2022 and 2021.

Investment in Minority Owned Joint Venture

The Company and Cleveland Clinic partnered to form a joint venture, under the name CCAW, JV LLC, to provide broad access to comprehensive and high acuity care services via digital care. The Company does not have a controlling financial interest in CCAW, JV LLC, but it does have the ability to exercise significant influence over the operating and financial policies of CCAW, JV LLC. Therefore, the Company accounts for its investment in CCAW, JV LLC using the equity method of accounting. The joint venture is considered a variable interest entity under ASC 810-10, but the Company is not the primary beneficiary as it does not have the power to direct the activities of the joint venture that most significantly impact its performance. The Company’s evaluation of ability to impact performance is based on Cleveland Clinic’s managing directors and Cleveland Clinic’s ability to appoint and remove the chairperson who has the ability to cast the tie breaking vote on the most significant activities.

During the year ended December 31, 2020, the Company contributed $2,940 as its initial investment for a 49% interest in CCAW, JV LLC. The agreement also requires aggregate total capital contributions by the Company up to an additional $11,800 in two phases, which is yet to be defined. During the years ended December 31, 2022 and 2021 the Company made a capital contribution of $1,960 and $2,548 related to a portion of the phase one capital commitment. For the year ended December 31, 2022 and 2021, the Company recognized a loss of $2,278 and $3,132 as its proportionate share of the joint ventures results of operations, respectively. Accordingly, the carrying value of the equity method investment as of December 31, 2022 and 2021 was $(150) and $168, respectively. As the share of losses exceeds the carrying amount of the investment, the carrying amount as of December 31, 2022 it is included in the balance of accrued expenses and other current liabilities on the consolidated balance sheet.

Advertising Costs

Advertising costs are expensed as incurred and are included in sales and marketing expense in the consolidated statement of operations and comprehensive loss. For the years ended December 31, 2022, 2021 and 2020, the Company’s advertising expenses were $6,607, $5,604 and $3,860, respectively.

Research and Development Costs

Research and development costs are expensed as incurred. Research and development expenses include payroll, employee benefits and other expenses associated with product development.

Internal-Use Software

The Company evaluates development costs incurred to develop functionality in connection with its internal-use software for capitalization. Qualifying costs incurred to develop internal-use software are capitalized when (i) the preliminary project stage is completed, (ii) management has authorized further funding for the completion of the project and (iii) it is probable that the project will be completed and performed as intended. Capitalization of these costs ceases once the project is substantially complete and the software is ready for its intended purpose. Capitalized internal-use software costs are included in intangible assets on the consolidated balance sheet for the year ended December 31, 2022 and these costs were not material to the Company’s consolidated financial statements during the year ended December 31, 2021. There were no impairment charges related to capitalized software development costs during 2022. Capitalized software development costs are amortized using the straight-line method over an estimated useful life of three years.

Stock-Based Compensation

The Company measures all stock options and other stock-based awards granted to employees and directors based on the fair value on the date of the grant and recognizes compensation expense of those awards, net of estimated forfeitures, over the requisite service period, which is generally the vesting period of the respective award. Generally, the Company issues stock options, restricted stock units (“RSU’s”) and performance-based market condition share awards ("PSU's") to employees. Stock options and RSUs only have service-based vesting conditions and the Company records the expense for these awards using the straight-line method. Stock option awards and restricted stock units issued to the co-CEOs prior to the IPO or as a result of the IPO (“IPO RSUs”) were expensed when granted as the requisite future service of the awards is not substantive for accounting purposes. PSUs have multiple tranches each with certain market capitalization milestones and service-based vesting conditions and the Company records the expense for these awards over the estimated life of each tranche.

The Company classifies stock-based compensation expense in its consolidated statements of operations and comprehensive loss in the same manner in which the award’s recipient’s payroll costs are classified.

The Company recognizes compensation expense for only the portion of awards that are expected to vest. In developing a forfeiture rate estimate, the Company has considered its historical experience to estimate pre-vesting forfeitures for service-based awards. The impact of a forfeiture rate adjustment will be recognized in full in the period of adjustment, and if the actual forfeiture rate is materially different from the Company’s estimate, the Company may be required to record adjustments to stock-based compensation expense in future periods.

The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model. The restricted stock units issued to the co-CEOs as a result of the IPO had the fair value estimated using a binomial lattice approach. The Company historically had been a private company and lacks company-specific historical and implied volatility information. Therefore, it estimates its expected stock volatility based on the historical volatility of a publicly traded set of peer companies and expects to continue to do so until such time as it has adequate historical data regarding the volatility of its own traded stock price. The expected term of the Company’s stock options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. The expected dividend yield is based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future.

The fair value of the PSUs is estimated using a Monte-Carlo valuation simulation. Similar to stock options, the Company estimates its expected stock volatility based on the historical volatility of a publicly traded set of peer companies and expects to continue to do so until such time as it has adequate historical data regarding the volatility of its own traded

stock price. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. The expected dividend yield is based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future.

Deferred Contract Acquisition Costs

The Company capitalizes sales commissions and certain parts of the Company bonus that are incremental to the acquisition of client contracts. These costs are recorded as deferred contract acquisition costs on the consolidated balance sheets. The Company determines whether costs should be deferred based on its sales compensation plans if the commissions are in fact incremental and would not have occurred absent the client contract.

Sales commissions are paid upon the initial acquisition of a contract and are amortized over an estimated period of benefit of five years. Amortization is recognized on a straight-line basis commensurate with the pattern of revenue recognition. The Company determined the period of benefit for commissions paid for the acquisition of initial contracts by taking into consideration the commitment term of the client contract, the nature of the Company’s technology development life cycle, and an estimated client relationship period. Amortization of deferred contract acquisition costs is included in sales and marketing expenses in the accompanying consolidated statements of operations and comprehensive loss.

The Company reviews these deferred costs to determine whether events or changes in circumstances have occurred that could impact the period of benefit of these deferred contract acquisition costs. There were no impairment losses recorded during the periods presented.

Deferred Contract Fulfillment Costs

The Company capitalizes costs to fulfill contracts with clients in “Prepaid expenses and other current assets” and “Other assets” on its consolidated balance sheet. The Company amortizes these costs to cost of revenue in the consolidated statement of operations and comprehensive loss consistent with the revenue recognition of the performance obligations in the associated contracts. The Company assesses these costs for impairment at the end of each reporting period. There were no impairment losses recorded during the periods presented.

Comprehensive Loss

Comprehensive loss includes net loss as well as other changes in stockholders’ equity (deficit) that result from transactions and economic events other than those with stockholders.

Income Taxes

The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the financial statements or in the Company’s tax returns. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using the enacted tax rates in effect for the year in which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income, and to the extent it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established through a charge to income tax expense. The potential for recovery of deferred tax assets is evaluated by considering taxable income in carryback years, existing taxable temporary differences, prudent and feasible tax planning strategies and estimating the future taxable profits.

The Company accounts for uncertainty in income taxes recognized in the financial statements by applying a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50%

likelihood of being realized upon ultimate settlement. The provision for income taxes includes the effects of any resulting tax reserves, or unrecognized tax benefits, that are considered appropriate as well as the related net interest and penalties.

Net Loss per Share

The Company follows the two-class method when computing net loss per share as the Company has issued shares that meet the definition of participating securities. The two-class method determines net loss per share for each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires income or loss available to common stockholders for the period to be allocated between common and participating securities based upon their respective rights to receive dividends as if all income or losses for the period had been distributed.

Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding for the period. Diluted net loss attributable to common stockholders is computed by adjusting net losses attributable to common stockholders to reallocate undistributed earnings based on the potential impact of dilutive securities. Diluted net loss per share attributable to common stockholders is computed by dividing the diluted net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding for the period, including potential dilutive common shares.

The Company’s convertible preferred stock contractually entitles the holders of such shares to participate in dividends, but contractually does not require the holders of such shares to participate in losses of the Company. Accordingly, in periods in which the Company reports a net loss attributable to common stockholders, diluted net loss per share attributable to common stockholders is the same as basic net loss per share attributable to common stockholders since dilutive common shares are not assumed to have been issued, as their effect is anti-dilutive. The Company reported a net loss attributable to common stockholders for the years ended December 31, 2022, 2021 and 2020.

Revenue Recognition

Platform subscription

The Company generates revenue primarily from contracts with clients who purchase subscriptions to access the Company’s enterprise software which includes access to the Company’s affiliated medical group.

The Company’s clients do not have the right to take possession of the Company’s software operating its digital care platform at any time. Instead, clients are granted access to the Company’s platform over the contractual period. Access to the platform, including the stand ready obligation to provide access to the affiliated medical group, represents a series of distinct services as the Company continually provides access to and fulfills its obligation to the client over the contract term. The typical contract term is three years. Most of the Company’s contracts are non-cancelable over the contractual term. Clients typically have the right to terminate their contracts for cause if the Company fails to perform in accordance with the contractual terms.

For clients who purchase access to the enterprise digital care platform (the “Amwell Platform”), the Company hosts a dedicated instance of the Amwell Platform, white-labeled under the client’s own name, branding, and with customized workflows and operating choices. The implementation services for the Amwell Platform are not distinct within the context of the contract because the Company’s promise to perform the implementation services are not separately identifiable from the access to the Amwell Platform. The implementation services, which customize the client’s Amwell Platform, are integral to the client’s ability to derive its intended benefit from the Amwell Platform. The development and implementation services generally span several months and cannot be performed by another entity. Therefore, access to the Amwell Platform and the implementation services are bundled together and represent a single performance obligation. The fixed consideration related to the single performance obligation is generally recognized on a straight-line basis over the contract term beginning on the date access to the Amwell Platform is provided. The Company uses a time-elapsed method to measure progress because the Company transfers control evenly over the contractual period.

Clients can also purchase access to the Company’s co-branded digital care practice hosted on the Company’s shared services platform (the “Amwell Practice”). The implementation services for the Amwell Practice do not significantly modify or customize the Amwell Practice, typically occur over a few days, and can be performed by other entities. Therefore, access to the Amwell Practice and the implementation services are separate outputs promised by the Company and represent two distinct performance obligations.

Clients may be billed prior to the related goods or services being transferred to the client. In determining the transaction price, the Company adjusts the promised amount of consideration for a significant financing component if the timing of payments agreed to by the parties in the contract provide the client a significant benefit of financing. The Company has applied the practical expedient and recognizes the promised amount of consideration without adjusting for the effects of a significant financing component if the Company expects, at contract inception, that the period between the transfer of goods or services to the client when the client pays for that good or service will be one year or less. As of December 31, 2022, the effect of the financing component is not significant and does not materially change the amount of revenue that would be recognized under a contract.

The total fixed consideration is allocated to each distinct performance obligation based on standalone selling price (“SSP”) which reflects the amount that the Company charges for each performance obligation if it was sold separately in a standalone sale. The fixed consideration to access the Amwell Practice is recognized on a straight-line basis over the contract term beginning on the date access to the Amwell Practice is provided. A time-elapsed method is used to measure progress because the Company transfers control evenly over the contractual period. The fixed consideration related to the implementation services is recognized as the services are performed.

In addition to the fixed consideration received from the Amwell Platform and Amwell Practice, the Company can also receive variable consideration based on the number of members serviced (that is, a stated fee per member per month). The Company allocates the per member per month variable consideration to the month that the fee is earned, correlating with the amount of services it is providing, which is consistent with the allocation objective of the series guidance. Revenue recognized from the per member per month variable consideration does not represent a significant portion of total revenue for the years ended December 31, 2022, 2021 and 2020.

Some contracts with clients contain a renewal option which allows the client to continue access to the Amwell Platform for a stated price after the initial contractual term has ended. These renewal options are evaluated on a case-by-case basis but generally do not provide a material right as they are priced at or above the price for the same service that the Company offers to similar clients and, as such, would not result in a separate performance obligation.

Visits

The Company also generates revenue when either the Amwell Platform or the Amwell Practice is utilized to conduct a medical visit. In the event of a visit, the fee that is earned upon completion of the visit is allocated to the specific day of performance, as the visit fee meets the criteria to allocate variable consideration to a distinct service within a series of distinct services that comprise the single performance obligation. Therefore, visit fees are recognized when the visits are completed, and the Company has delivered on its stand-ready obligation to provide access to the medical professional.

In addition, clients can visit with the Company’s affiliated medical group without purchasing access to an Amwell Platform or Amwell Practice. These direct-to-consumer virtual care visits are available through the Company’s website where clients can conduct a visit with the Company’s affiliated medical group for a fixed fee. The Company’s affiliated medical group is responsible for fulfilling the promise to the client to perform the medical visit. The Company has discretion in establishing the price for the visit, is responsible for the resolution of any client issues, and is exposed to credit risk for the receivable due from the client. Therefore, the Company recognizes the visit fee on a gross basis upon completion of the visit.

Other

Other revenue primarily represents professional services associated with the Amwell Platform. After implementation of Amwell Platform has been completed, some clients purchase other professional services, which are designed to help clients enhance their ability to use Amwell Platform. For the majority of arrangements, the Company prices these professional services on a time and material basis, has standalone selling price for these services, and recognizes revenue as services are performed. Other revenue also includes sale of hardware products, such as the Company’s digital care carts and kiosks. Revenue from the sale of hardware products to clients is recognized upon the transfer of control, which occurs upon shipment of the product.

Deferred Revenue

Deferred revenue includes amounts collected or billed in excess of revenue recognized. Deferred revenue is recognized as revenue as the related performance obligations are satisfied. Deferred revenue that will be recognized during the

succeeding twelve-month period is recorded as a current liability and the remaining portion is recorded as a noncurrent liability on the consolidated balance sheet.

Leases

The Company determines at the inception of a contract if such arrangement is or contains a lease. A contract is or contains a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The Company classifies leases at the lease commencement date as operating or finance leases and records a right-of-use asset and a lease liability on the consolidated balance sheet for all leases with an initial lease term of greater than 12 months. Leases with an initial term of 12 months or less are not recorded on the balance sheet, but payments are recognized as expense on a straight-line basis over the lease term.

The Company’s contracts may contain both lease and non-lease components. Non-lease components may include maintenance, utilities, and other operating costs. The Company combines the lease and non-lease components of fixed costs in its lease arrangements as a single lease component. Variable costs, such as utilities or maintenance costs, are not included in the measurement of right-of-use assets and lease liabilities, but rather are expensed when the event determining the amount of variable consideration to be paid occurs.

Lease liabilities and their corresponding right-of-use assets are recorded based on the present value of future lease payments over the expected lease term. The Company determines the present value of future lease payments by using its estimated secured incremental borrowing rate for that lease term as the interest rate implicit in the lease is not readily determinable. The Company estimates its secured incremental borrowing rate for each lease based on the rate of interest that the Company would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term.

Certain of the Company’s leases include options to extend or terminate the lease. The amounts determined for the Company’s right-of-use assets and lease liabilities generally do not assume that renewal options or early-termination provisions, if any, are exercised, unless it is reasonably certain that the Company will exercise such options.

Recently Issued and Adopted Accounting Pronouncements

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which simplifies the accounting for income taxes by removing certain exceptions and clarifying and amending existing guidance. The guidance was adopted effective January 1, 2021 and did not have a material impact on the consolidated financial statements.

In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”), which requires that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. To achieve this, an acquirer may assess how the acquiree applied Topic 606 to determine what to record for the acquired revenue contracts. Generally, this should result in an acquirer recognizing and measuring the acquired contract assets and contract liabilities consistent with how they were recognized and measured in the acquiree’s financial statements. The guidance was adopted effective July 1, 2021 and impacted the accounting of acquired deferred revenue for the Conversa and SilverCloud acquisitions that occurred in August 2021.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model. It also eliminates the concept of other-than-temporary impairment and requires credit losses related to available-for-sale debt securities to be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. These changes may result in earlier recognition of credit losses. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, which narrowed the scope and changed the effective date for non-public entities for ASU 2016-13. The FASB subsequently issued supplemental guidance within ASU No. 2019-05, Financial Instruments—Credit Losses (Topic 326): Targeted Transition Relief (“ASU 2019-05”). ASU 2019-05 provides an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis. The Company adopted ASU 2016-13 and the related clarifications in 2021. The adoption did not have a material effect on the Company’s consolidated financial statements.
