The preparation of the consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions about future events that affect the amounts reported in its consolidated financial statements and the accompanying notes. Future events and their effects cannot be determined with certainty. On an ongoing basis, management evaluates these estimates, judgments, and assumptions. Significant estimates and assumptions include but are not limited to: (1) revenue recognition, (2) accounts receivable and allowance for doubtful accounts, (3) long-lived asset recoverability, (4) useful lives of long-lived assets, (5) stock-based compensation, and (6) fair value measurements, including the fair value of the Earn-Out Shares. The Company bases these estimates on historical and anticipated results and trends and on various other assumptions that the Company believes are reasonable under the circumstances, including assumptions as to future events. Actual results could differ from those estimates, and any such differences may be material to the Company’s consolidated financial statements.

In March 2020 the World Health Organization declared the global novel coronavirus disease 2019 (“COVID-19”) outbreak a pandemic. The Company’s original sublease tenant in San Francisco was unable to fulfill its sublease obligations due to the pandemic’s impact on its business operations. The sublessee vacated the facility in February 2021 and a new sublessee was not secured until May 2021, at terms substantially similar to the original sublessee. For the years ended December 31, 2021 and 2020, the Company wrote-off $0.2 million and $0.3 million of sublease receivable against sublease income due to low probability of collection from the original sublessee. No other significant impacts to the Company’s operations due to the COVID-19 outbreak have occurred.

A performance obligation is a promise (or a combination of promises) in a contract to transfer distinct goods or services to a customer and is the unit of accounting under ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”) for purposes of revenue recognition. A contract’s transaction price is allocated to each separate performance obligation based on the standalone selling price and is recognized as revenue, when, or as, the performance obligation is satisfied. All of the Company’s contracts have a single performance obligation because the promise to transfer individual services is not separately identifiable from other promises in the contracts, and therefore, is not distinct.

The majority of the Company’s revenue arrangements are service contracts that range in duration from a few months to several years. Substantially all of the Company’s performance obligations, and associated revenue, are transferred to the customer over time. The performance obligation is satisfied over time and the Company generally recognizes revenue based on a cost-based input method, due to costs being incurred consistently throughout the life of the contract, as there is no single output measure that would fairly depict the transfer of control over the life of the performance obligation. Progress on the performance obligation is measured by the proportion of actual costs incurred to the total costs expected to complete the contract. Costs included in the measure of progress include direct labor and third-party costs (such as payments to investigators and other pass-through expenses for the Company’s clinical monitors). This cost-to-cost input method of revenue recognition requires the Company to make estimates of costs to complete its projects on an ongoing basis. Contract estimates are based on various assumptions to project future outcomes of events that often span several years and require significant judgment. These estimates are reviewed periodically, and any adjustments are recognized on a cumulative catch-up basis in the period they become known.

The Company generally receives compensation based on measuring progress toward completion using anticipated project budgets and direct labor and prices for each service offering. The Company is also reimbursed for certain third party pass-through and out-of-pocket costs. The pass-through costs are included in total operating expenses. The pass-through costs are also recognized as revenue on a gross basis as the Company is the principal in the relationship (i.e., the Company is primarily responsible for the services provided by third parties, and significantly integrates the services of third parties with its own services in delivering a combined output to the customer). In addition, in certain instances, a customer contract may include forms of variable consideration such as incentive fees, volume rebates or other provisions that can increase or decrease the transaction price. This variable consideration is generally awarded upon achievement of certain performance metrics, program milestones or cost targets. For the purpose of revenue recognition, variable consideration is assessed on a contract-by-contract basis and the amount included in the transaction price is estimated based on the Company’s anticipated performance and in consideration of all information that is reasonably available. Variable consideration is recognized as revenue if and when it is deemed probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved in the future.

The Company has one performance-based contract, which is unique in that the Company’s obligation to the customer is solely for the recruitment of successfully processed patients or “completers”. The successful recruitment of completers constitutes a single performance obligation to our customer. Completer revenue is recognized at a point in time, as completers are processed.

For contracts where the Company licenses its proprietary hosted software independently, value transfers to the customer over time as the customer has access to the system once it is live and continues to benefit over the life of the arrangement. Revenue is recorded straight line over the term of the hosting and maintenance period as there is no better measure of the transfer of value for these services.

Most of the Company’s contracts can be terminated by the customer without cause with a 30-day notice. In the event of termination, the Company’s contracts generally provide that the customer pay the Company for (i) fees earned through the termination date, (ii) fees and expenses for winding down the project, which include both fees incurred and actual expenses, (iii) non-cancellable expenditures, and (iv) in some cases, a fee to cover a portion of the remaining professional fees on the project.

Changes in the scope of work are common, especially under long-term contracts, and generally result in a change in the total contract transaction price. If the customer does not agree to a contract modification, the Company could bear the risk of cost overruns. Most of the Company’s contract modifications are for services that are not distinct from the services under the existing contract due to the significant integration service provided in the context of the contract and therefore result in a cumulative catch-up adjustment to revenue at the date of contract modification.

The Company capitalizes certain costs associated with commissions paid to its employees because these costs are incurred in obtaining contracts that have a term greater than one year and are expected to be recovered. Capitalized costs are included in prepaid expenses and other current assets in the accompanying balance sheet and are amortized to selling, general and administrative expenses on the consolidated statements of operations and comprehensive loss. The Company amortizes these costs in a manner that is consistent with the pattern of revenue recognition described above. The Company expenses costs to obtain contracts that have a term of one year or less when incurred.

Cost of revenues include the direct cost to conduct trials remotely and make available the Company’s technology solutions to its customers. Cost of revenues includes direct labor salaries, direct labor stock-based compensation, and third-party costs (such as payments to investigators, marketing costs, and other pass-through expenses) for the Company’s clinical trial revenue. Clinical trial marketing costs totaled $3.4 million and $6.8 million for the years ended December 31, 2021 and 2020, respectively. Clinical trial marketing costs were elevated in 2020 as compared to 2021 due to the impact of one particular study in 2020.

Selling, general and administrative expenses include costs related to sales, marketing, and administrative functions (including human resources, legal, finance, and general management) such as compensation and benefits, travel, professional services, facilities, recruiting and relocation, training, sales commissions and expenses for stock-based compensation, and information technology. Corporate branding and other marketing costs totaled $1.3 million and $0.3 million for the years ended December 31, 2021 and 2020, respectively.

Restructuring costs consist of one-time employee termination benefits. The Company accounts for restructuring costs in accordance with ASC Topic 420, Exit or Disposal Cost Obligations. This guidance requires that liabilities related to one-time employee termination benefits be measured and recognized at the date the entity notifies employees of termination, unless employees are required to render services beyond a minimum retention period, in which case the liability is recognized ratably over the future service period. Restructuring liabilities are included in accrued expenses.

Restricted cash consisted of funds held as security related to the Company’s credit instrument held as collateral on the Company’s operating lease that ended in April 2021. Restricted cash was classified as a current or long-term asset based on the timing and nature of when and how the cash was expected to be used or when the restrictions were expected to lapse. As of December 31, 2021, the Company had no restricted cash balance. The Company had a current restricted cash balance of $1.0 million as of December 31, 2020.

The Company establishes prerequisites for billings based on contractual terms, including payment schedules and the completion of milestones. In general, the Company’s intention in its invoicing and related payment terms is to maintain cash neutrality over the life of the contract. Generally, the payment terms are 30 to 90 days. Upfront payments, when they occur, are intended to cover certain expenses the Company incurs at the beginning of the contract. Neither the Company nor its customers view such upfront payments and contracted payment schedules as a means of financing.

Unbilled services represent revenue earned and recognized for services performed for which amounts have not yet been billed to the customer in accordance with contractual terms. Contractual provisions and payment schedules may or may not correspond to the timing of the performance of services under the contract. Unbilled services include contract assets, under which the right to bill the customer is subject to factors other than the passage of time, such as the satisfaction of milestones. Accounts receivable and unbilled services are recorded, net, on the balance sheet.

Deferred revenue is a contract liability that consists of customer payments received in advance of performance. The Company reduces deferred revenue and recognizes revenue as the related performance obligations for services are performed. Deferred revenue is classified as a current liability on the balance sheet when the Company expects to recognize the associated revenue in less than one year, and a long-term liability when the Company expects to recognize the associated revenue in excess of one year.

The Company carries its accounts receivable at net realizable value. The Company maintains a credit approval process and makes judgments to assess its customers’ ability to pay for contracted services. The Company monitors its customers’ credit worthiness and applies judgment in establishing a provision for estimated credit losses based on historical experience, the aging of receivables and customer and industry specific circumstances. The Company continuously monitors collections and payments from its customers and has a policy to write off uncollectible invoices once appropriate collection efforts have been exhausted. The allowance for doubtful accounts is included in accounts receivable on the consolidated balance sheets.

The Company’s internal use proprietary hosted software organizes workflows, captures real-time evidence, and harmonizes data during clinical trial support or enhancement for its customers. Capitalized software is recorded at cost less accumulated amortization. The Company capitalizes software development cost related to the development of the Company’s proprietary platform in accordance with ASC Topic 350, Intangibles—Goodwill and Other. Internal and external costs incurred during the preliminary stage are expensed as incurred. Costs incurred during the development stage are capitalized and consist of payroll labor, and benefits to the extent of time spent directly on the project and external direct costs of materials and labor. Training and maintenance costs are expensed as incurred. The Company commences amortization once the respective assets are placed into service. The estimated useful life for capitalized software is 3 years. Software cloud computing arrangements that do not contain software licenses are accounted for as service contracts.

Assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the expected undiscounted future cash flow from the use of the asset and its eventual disposition is less than the carrying amount of the asset, an impairment loss is recognized and measured using the fair value of the related asset. No material impairments were recognized during the years ended 2021 or 2020.

On January 1, 2020, the Company adopted Accounting Standards Update (ASU) 2016-02 “Leases” (“Topic 842”) under the revised modified retrospective approach which recognizes the impact of initially applying the new leases standard as a cumulative effect adjustment to accumulated deficit as of the adoption date. Additionally, the Company elected the package of practical expedients permitted under the ASC Topic 842 transition guidance. Under this election, the Company need not reassess (i) the historical lease classification, (ii) whether any expired or existing contract is or contains a lease, or (iii) the initial direct costs for any existing leases.

The Company determines if an arrangement is a lease at inception of the contract. A contract contains a lease if the Company controls the use of an identified asset. Control exists if the Company can direct the use of and obtain substantially all the economic benefit of the asset. Operating lease right-of-use (“ROU”) assets and lease liabilities are recorded on our balance sheet and are measured based on the present value of the future minimum lease payments over the lease term at commencement date. The Company’s uses its incremental borrowing rate at lease commencement in determining the present value of future payments. In addition, the operating lease ROU asset includes any prepaid lease payments and initial direct costs and excludes lease incentives. If the Company has an option to extend or terminate a lease and is reasonably certain to exercise that option, the extension or termination is included in the lease term used to measure the lease liability and related ROU asset. Lease expense for minimum lease payments is recognized on a straight-line basis over the term of the lease.

The Company has elected to account for lease components and non-lease components in a contract as a single lease component. For short-term leases (those with a term of one year or less), the Company has elected not to recognize ROU assets and lease liabilities. Lease payments on short-term leases are recognized as lease expense on a straight-line basis over the lease term.

The Company accounts for stock options under the fair value method and uses the Black-Scholes model to estimate the value of such awards granted to its employees, consultants, and non-executive directors. Within this model, expected volatility is based upon the historical volatility of a peer group for a period equal to the expected term, as the Company does not have adequate history to calculate its own volatility. The Company believes the expected volatility will approximate the historical volatility of the peer group. The Company does not currently anticipate paying dividends. The

The Company accounts for Earn-Out Shares issued to Legacy Science 37 option holders at fair value and uses a Monte Carlo simulation to estimate the value of such Earn-Out Shares on the grant date. Within this model, expected volatility is based upon the historical volatility of a peer group for a period equal to the expected term, as the Company does not have adequate history to calculate its own volatility. The expected term represents the derived service period as determined in the Monte Carlo simulation valuation model. The risk-free interest rate is based on the United States Treasury yield curve at the time of the grant.

Fair value is the price that would be received to sell an asset or paid to transfer a liability between market participants in the principal market or the most advantageous market when no principal market exists. Market participants are assumed to be independent, knowledgeable, able, and willing to transact an exchange and not under duress. Considerable judgment may be required in interpreting market data used to develop the estimates of fair value. Accordingly, estimates of fair value are not necessarily indicative of the amounts that could be realized in a current or future market exchange. Fair values for substantially all of the Company’s financial and nonfinancial instruments were measured using market, income, or cost approaches. The three levels of input are as follows:

Level 2: Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Financial instruments, including cash and cash equivalents, are recorded at cost, which approximates fair value. Former holders of shares of Science 37 common stock were allocated Earn-Out Shares in connection with the completion of the Merger. These Earn-Out Shares are accounted for as a liability and require fair value measurement on a recurring basis. Due to the significant unobservable inputs that are required to value these shares, they are classified as Level 3 in the fair value hierarchy. Please refer to Note 15 for additional details surrounding the valuation methodology for the Earn-Out Shares.

Income taxes are recorded in accordance with ASC Topic 740, Income Taxes, which provides for deferred taxes using an asset and liability approach. The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities, as well as for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the enacted tax rates that are expected to apply to taxable income for the years in which those tax assets and liabilities are expected to be realized or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company records valuation allowances to reduce deferred tax assets to the amount the Company believes is more likely than not to be realized.

The Company recognizes uncertain tax positions when the positions will more likely than not be upheld on examination by the taxing authorities based solely upon the technical merits of the positions. The Company recognizes interest and penalties, if any, related to unrecognized income tax uncertainties in income tax expense.

Diluted net loss per share is calculated by adjusting weighted average shares outstanding for the dilutive effect of common stock equivalents outstanding for the period, determined using the treasury-stock method. For purposes of the diluted net loss per share calculation, preferred stock, stock options and warrants are considered to be common stock equivalents but are excluded from the calculation of diluted net loss per share because their effect would be anti-dilutive.

Operating segments are defined as components of an entity for which separate financial information is available and that are regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company has determined that its Senior Executive Committee, which includes the Chief Executive Officer, together with the Board of Directors is the CODM. The Company operates in a single operating segment as the CODM reviews financial information presented on a consolidated basis, at the Company level, for the purposes of making operating decisions, allocation of resources, and evaluating financial performance.

As an emerging growth company (“EGC”), the Jumpstart Our Business Startups Act (“JOBS Act”) allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are applicable to private companies. The Company has elected to use the extended transition period under the JOBS Act until such time the Company is not considered to be an EGC. The adoption dates are discussed in the section below to reflect this election.

The Company is also a smaller reporting company as defined in Item 10(f) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure requirements, including, among other things, providing only two years of audited financial statements. To the extent the Company takes advantage of such reduced disclosure requirements, it may make the comparison of its financial statements with other public companies difficult or impossible.

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (ASU 2019-12), which eliminates certain exceptions to the guidance in Income Taxes (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 new guidance also simplifies 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. The Company adopted ASU 2019-12 effective January 1, 2021. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements and related disclosures.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This guidance introduces a new model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses. The standard replaces the incurred loss impairment methodology in current GAAP with one that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The Company does not expect the adoption of the guidance to have a material effect on the Company’s consolidated financial statements. This is based on factors including the Company’s assessment of historical losses, customers’ creditworthiness, and the fact that the Company’s trade receivables are short term in duration. The Company plans to adopt the provisions of ASU 2016-13 no later than January 1, 2023. Management is currently evaluating the potential impact of these changes on the consolidated financial statements of the Company.
