| SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Emerging Growth Company and Smaller Reporting Company Status Following the Business Combination, the Company qualifies as an emerging growth company (‘‘EGC’’) as defined in the Jumpstart our Business Startups (‘‘JOBS’’) Act. The JOBS Act permits companies with EGC status to take advantage of an extended transition period to comply with new or revised accounting standards, delaying the adoption of these accounting standards until they would apply to private companies. The Company intends to use this extended transition period to enable the Company to comply with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date the Company (i) is no longer an EGC or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, the Company's condensed consolidated financial statements may not be comparable to companies that comply with the new or revised accounting standards as of public company effective dates. In addition, the Company intend to rely on the other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, as an EGC, the Company is not required to, among other things: (i) provide an auditor’s attestation report on our system of internal control over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act; (ii) provide all of the compensation disclosures that may be required of non-EGCs under the Dodd-Frank Wall Street Reform and Consumer Protection Act; (iii) comply with the requirements of the Public Company Accounting Oversight Board regarding the communication of critical audit matters in the auditor’s report on the consolidated financial statements (auditor discussion and analysis); and (iv) disclose certain executive compensation-related items such as the correlation between executive compensation and performance and comparisons of the Chief Executive Officer’s compensation to median employee compensation. The Company will remain an emerging growth company until the earlier of: (i) the last day of the fiscal year (a) following the fifth anniversary of the closing of ENVI’s initial public offering, (b) in which the Company has total annual gross revenue of at least $1.1 billion, or (c) in which the Company is deemed to be a large accelerated filer, which means the market value of its common equity that is held by non-affiliates exceeds $700.0 million as of the last business day of its most recently completed second fiscal quarter; and (ii) the date on which the Company has issued more than $1.0 billion in non-convertible debt securities during the prior three-year period. References herein to “emerging growth company” have the meaning associated with it in the JOBS Act. The Company is also a “smaller reporting company” as defined in the Exchange Act. The Company may continue to be a smaller reporting company even after the Company is no longer an emerging growth company. The Company may take advantage of certain of the scaled disclosures available to smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as the market value of the Company's voting and non-voting Common Stock held by non-affiliates is less than $250.0 million measured on the last business day of the Company's second fiscal quarter, or the Company's annual revenue is less than $100.0 million during the most recently completed fiscal year and the market value of the Company's voting and non-voting Common Stock held by non-affiliates is less than $700.0 million measured on the last business day of the Company's second fiscal quarter. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses, and the disclosure of contingent assets and liabilities as of and during the reporting period. The Company bases its estimates and assumptions on historical experience when available and on various factors that it believes to be reasonable under the circumstances. This process may result in actual results differing materially from those estimated amounts used in the preparation of the financial statements if these results differ from historical experience, or other assumptions do not turn out to be substantially accurate, even if such assumptions are reasonable when made. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, revenue recognition, the accrual of research and development costs, acquisition of in-process research and development assets, useful lives assigned to property and equipment, and the fair value of warrant liabilities. The Company assesses estimates on an ongoing basis; however, actual results could materially differ from those estimates. Operating Segments Operating segments are identified as components of an enterprise about which separate discrete financial information is made available for evaluation by the chief operating decision maker (“CODM”) in making decisions regarding resource allocation and assessing performance. The CODM is the Company’s Chief Executive Officer. The Company manages its operations as a single segment for the purposes of assessing performance and making operating decisions. Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Investments qualifying as cash equivalents primarily consist of money market funds. The Company’s cash and cash equivalents in the condensed consolidated balance sheets at June 30, 2022 and December 31, 2021, were approximately $ 44.1 million and $ 31.4 million, respectively. Restricted Cash The Company maintains letters of credit in conjunction with the Company’s lease agreements. As of June 30, 2022 and December 31, 2021, the underlying cash balance securing these letters of credit of approximat ely $ 1.3 million and $ 0.4 million, respectively, was classified as a noncurrent asset in the condensed consolidated balance sheets based on the terms of the lease agreement. Accounts Receivable Our accounts receivable consists of amounts due from one customer. We extend credit to our customer based on our evaluation of the customer’s financial condition. Accounts receivable are stated at amounts due net of applicable prompt pay discounts and other adjustments. We assess the need for an allowance for doubtful accounts by considering a number of factors, including the length of time trade accounts receivable are past due and the customer’s ability to pay its obligation. Based on a review of these factors, as of June 30, 2022, we determined that an allowance for doubtful accounts was not required. Concentrations of Credit Risk The Company has no significant off-balance sheet credit risk. Financial instruments that potentially subject the Company to significant concentration of credit risk consist primarily of cash, cash equivalents and accounts receivable. The Company maintains deposits in accredited financial institutions in excess of federally insured limits. The Company deposits its cash and cash equivalents in financial institutions that it believes have high credit quality, has not experienced any losses on such accounts and does not believe it is exposed to any unusual credit risk beyond the normal credit risk associated with commercial banking relationships. Concentration of credit risk with respect to accounts receivable is limited to customers with whom the Company has entered into collaboration agreements. The Company has not written off any accounts receivable to date. To control credit risk, the Company performs regular credit evaluations of its customers’ financial condition. Fair Value Measurements ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), establishes a fair value hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. ASC 820 identifies fair value as the exchange price, or exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a three-tier fair value hierarchy that distinguishes between the following: • Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. • Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for a similar asset or liability, either directly or indirectly. • Level 3 inputs are unobservable inputs that reflect the Company’s own assumptions about the inputs that market participants would use in pricing the asset or liability. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Property and Equipment Property and equipment are recorded at cost and depreciated over the estimated useful lives of the related assets using the straight-line method. Maintenance and repairs to an asset that do not improve or extend its life are expensed in the period incurred. Expenditures made to improve or extend the life of property and equipment are capitalized. Leasehold improvements are depreciated over the shorter of the useful life of the improvements or the remaining term of the associated lease. The estimated useful lives of property and equipment are as follows:
ESTIMATED USEFUL LIFE
Manufacturing equipment 10 years
Furniture and fixtures 7 years
Laboratory equipment 5 years
Computer equipment and software 3 years
Leasehold improvements Shorter of useful life or lease term Property and equipment subject to a capital lease are depreciated over the shorter of the useful life or the term of the lease. Construction in progress is stated at cost, which includes direct costs attributable to the setup or construction of the related asset. When assets are retired or otherwise disposed of, the assets and related accumulated depreciation are eliminated from the accounts and any resulting gain or loss is reflected in the Company’s statement of operations. Acquired In-process Research and Development The Company measures and recognizes acquisitions that are not deemed to be business combinations as acquisitions of assets based on the cost to acquire the assets, which includes transaction costs, and the consideration is allocated to the items acquired based on a relative fair value methodology. Goodwill is not recognized in asset acquisitions. In an asset acquisition, the cost allocated to acquire in-process research and development with no alternative future use is charged to research and development expense at the acquisition date. At the time of acquisition, the Company determines if a transaction should be accounted for as a business combination or acquisition of assets. Impairment of Long-lived Assets The Company evaluates its long-lived assets, which consist primarily of property and equipment, for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Such events and circumstances include, but are not limited to, significant decreases in the market value of an asset, adverse changes in the extent or manner in which the asset is being used, or significant changes in business climate. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted net cash flows expected to be generated by the asset. If such assets are considered impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds the fair value of the asset. During the six months ended June 30, 2022 and 2021 , no impairment indicators were identified and no impairments were recorded. Warrants The Company applies relevant accounting guidance for warrants to purchase the Company’s stock based on the nature of the relationship with the counterparty. For warrants issued to investors or lenders in exchange for cash or other financial assets, the Company follows guidance issued within ASC 480, Distinguishing Liabilities from Equity (“ASC 480”), and ASC 815, Derivatives and Hedging (“ASC 815”), to assist in the determination of whether the warrants should be classified as liabilities or equity. Warrants that are determined to require liability classification are measured at fair value upon issuance and are subsequently remeasured to their then fair value at each subsequent reporting period with changes in fair value recorded in current earnings. Warrants that are determined to require equity classification are measured at fair value upon issuance and are not subsequently remeasured unless they are required to be reclassified. For warrants issued to nonemployees for goods or services, or to customers as non-cash consideration, the Company follows guidance issued within ASC 718, Compensation – Stock Compensation (“ASC 718”), to determine whether the share-based payments are equity or liability classified. Such warrants are measured at fair value on the grant date. The related expense or reduction in transaction price is recognized in the same period and in the same manner as if the Company had paid cash for the goods or services, or in the same manner that transfer of control of the related performance obligations occurs. Contract Revenue The Company recognizes revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”), which provides a five-step model for recognizing revenue from contracts with customers as follows: • Identify the contract with a customer • Identify the performance obligations in the contract • Determine the transaction price • Allocate the transaction price to the performance obligations in the contract • Recognize revenue when or as performance obligations are satisfied Under ASC 606, an entity recognizes revenue when or as its customer obtains control of distinct promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. Our customer arrangements primarily consist of a license, rights to our intellectual property, and research and developments services. Performance obligations are promises in a contract to transfer a distinct good or service to the customer and are considered distinct when (i) the customer can benefit from the good or service on its own or together with other readily available resources and (ii) the promised good or service is separately identifiable from other promises in the contract. In assessing whether promised goods or services are distinct, we consider factors such as the stage of development of the underlying intellectual property, the capabilities of the customer to develop the intellectual property on its own, or whether the required expertise is readily available and whether the goods or services are integral or dependent to other goods or services in the contract. The Company estimates the transaction price based on the amount expected to be received for transferring the promised goods or services in the contract. The consideration may include fixed consideration or variable consideration. At the inception of each arrangement that includes variable consideration, the Company evaluates the amount of potential payments and the likelihood that the payments will be received. The Company utilizes either the most likely amount method or expected amount method to estimate the amount expected to be received based on which method best predicts the amount expected to be received. The amount of variable consideration, which is included in the transaction price, may be constrained and is included in the transaction price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period when the variability is resolved. For revenue related to sales-based royalties received from licensees, including milestone payments based on the level of sales, where the license is deemed to be the predominant item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). The Company allocates the transaction price based on the estimated stand-alone selling price of each of the performance obligations and develops assumptions that require judgment to determine the stand-alone selling price for each performance obligation identified in a contract with a customer. The Company utilizes key assumptions to determine the stand-alone selling price for service obligations, which may include other comparable transactions, pricing considered in negotiating the transaction, and the estimated costs. Any variable consideration is allocated specifically to one or more performance obligations in a contract when the terms of the variable consideration relate to the satisfaction of the performance obligation and the resulting amounts allocated are consistent with the amounts we would expect to receive for the satisfaction of each performance obligation. The consideration allocated to each performance obligation is recognized as revenue when control is transferred for the related goods or services, which is either over time or at a point in time. Revenue is recognized over time if either (i) the customer simultaneously receive and consumes the benefits provided by the entity’s performance, (ii) the entity’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced, or (iii) the entity’s performance does not create an asset with an alternative use to the Company and the Company has an enforceable right to payment for performance completed to date. If the entity does not satisfy a performance obligation over time, the related performance obligation is satisfied at a point in time by transferring the control of a promised good or service to the customer. For contracts that include a license of intellectual property (“IP”), the Company applies judgment to determine if the license of IP is distinct from other promises in the contract. License of IP that are determined to be distinct from other promises in the contract are recognized as revenue at a point in time when the license of IP is transferred to the customer and the customer can use and benefit from the license. For licenses of IP that are combined with other promises in a contract, the Company uses judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition. Determining the revenue recognition of a license of IP requires significant judgment and is discussed further in for the Company’s license and collaboration agreements in Note 4, License Agreement . At the inception of a contract that includes development or regulatory milestone payment, the Company evaluates the probability of reaching the milestones and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable a significant reversal of revenue would not occur in the future, the associated milestone value is included in the transaction price. Milestone payments that are not within the Company’s control or the licensee’s control, such as milestone payments for regulatory approvals, are not considered probable of being achieve until those approvals are received. Therefore, related revenue associated with the milestone payment is constrained as management is unable to assert that a significant reversal or revenue would not be possible. At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of such development and regulatory milestone payments and any constraints applied, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are generally recorded on a cumulative catch-up basis, which would affect revenues and earnings in the period of adjustment. Development or regulatory milestone payments are allocated either among the various performance obligations included in a contract on a relative standalone selling price basis, or to one or more specific performance obligations to which the milestone payment primarily relates. For contracts that include commercial milestone payments, which are based on the achievement of future sales, and sales-based royalties, if the license is determined to be the predominant item to which the commercial milestones and royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the milestone or royalty has been allocated has been satisfied (or partially satisfied). Grant Revenue In July 2020, we entered into a grant agreement with the Bill & Melinda Gates Foundation to advance research in in vivo gene therapy for sickle cell disease and to explore new, low-cost capabilities for the in vivo functional cure of sickle cell and/or durable suppression of HIV in developing countries. The grant agreement with the Bill & Melinda Gates foundation provides for payments for reimbursed costs, which include general and administrative costs. As we are performing services under the agreement that are consistent with the Company’s ongoing central activities and we have determined that we are the principal in the agreement, we recognize grant revenue as we perform services under this agreement when the funding is committed, which occurs as underlying costs are incurred. Revenues and related expenses are presented gross in the condensed consolidated statements of operations as we have determined that we are the primary obligor under the agreement relative to the research and development services we perform as the lead technical expert. Deferred Revenue Amounts received prior to satisfying the revenue recognition criteria are recorded as deferred revenue in the Company’s condensed consolidated balance sheets. If the related performance obligation is expected to be satisfied within the next twelve months, the related deferred revenue will be classified in current liabilities. Deferred Financing Costs The incremental cost, including the fair value of warrants, directly associated with obtaining debt financing is capitalized as deferred financing costs upon the issuance of the debt and amortized over the term of the related debt agreement using the effective-interest method with such amortized amounts included as a component of interest expense in the condensed consolidated statement of operations. Unamortized deferred financing costs are presented on the condensed consolidated balance sheets as a direct deduction from the carrying amount of the related debt obligation. Research and Development Costs Research and development expenses consist primarily of costs related to discovery and research and development of products, including personnel expenses, stock-based compensation expense, allocated facility-related and depreciation expenses, third-party license fees, and external costs of outside vendors engaged to conduct field trials and clinical development activities. The Company records accruals for estimated costs relating to our field trials, preclinical studies, and manufacturing development. A portion of our field trials, preclinical studies, and manufacturing development activities are conducted by third-party service providers, including contract research organizations and contract manufacturing organizations. The financial terms of these contracts may result in payments that do not match the periods over which materials or services are provided. We accrue the costs incurred under the agreements based on an estimate of actual work completed in accordance with the agreements. In the event we make advance payments for goods or services that will be used or rendered for future research and development activities, the payments are deferred and capitalized as a prepaid expense and recognized as expense as the goods are received or the related services are rendered. Research and development costs that do not meet the requirements to be recognized as an asset as the associated future benefits are uncertain and there is no alternative future use at the time the costs were incurred are expensed as incurred. General and Administrative Expenses The Company expenses general and administrative costs to operations as incurred. General and administrative expenses consist primarily of compensation, benefits, and other employee-related expenses for personnel in the Company’s administrative, finance, legal, information technology, business development, communications, and human resources functions. Other costs include the legal costs incurred in connection with filing and prosecuting patent and trademark applications, general and administrative related facility costs, insurance costs and professional fees for accounting, tax, consulting, legal and other services. Stock-Based Compensation Expense The Company accounts for all stock-based payment awards granted to employees and non-employees as stock-based compensation expense at grant date fair value. The Company’s stock-based payments include stock options and grants of common stock, including common stock subject to vesting. The measurement date for employee and non-employee awards is the date of grant, and stock-based compensation costs are recognized as expense over the recipient’s requisite service period, which is the vesting period, on a straight-line basis. The Company has also issued common stock options with milestone or performance-based vesting conditions and recorded the expense for these awards if or when it was deemed probable that the milestone or performance condition would be achieved. Stock-based compensation is classified in the accompanying statements of operations based on the function to which the related services are provided. The Company recognizes stock-based compensation expense for the portion of awards that have vested. Forfeitures are accounted for as they occur. The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model. The Company has historically 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 Company uses the simplified method as prescribed by the Securities and Exchange Commission Staff Accounting Bulletin No. 107, Share-Based Payment , to calculate the expected term for options granted to employees and non-employees, whereby, the expected term equals the arithmetic average of the vesting term and the original contractual term of the options due to its lack of sufficient historical data. The expected term of stock options granted to non-employees is determined in the same manner as stock options granted to employees. 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. Expected dividend yield is based on the fact that the Company has never paid cash dividends on common stock and does not expect to pay any cash dividends in the foreseeable future. Net Loss per Share Basic net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted net loss per share is computed using the weighted-average number of common shares outstanding during the period and, if dilutive, the weighted-average number of potential shares of common stock. Net loss per share attributable to common stockholders is calculated using the two-class method, which is an earnings allocation formula that determines net loss per share for the holders of the Company’s common shares and participating securities. The weighted-average number of common shares included in the computation of diluted net loss gives effect to all potentially dilutive common equivalent shares, including outstanding stock options, warrants and unvested restricted stock. Common stock equivalent shares are excluded from the computation of diluted net loss per share if their effect is antidilutive. In periods in which the Company reports a net loss attributable to common stockholders, diluted net loss per share attributable to common stockholders is generally the same as basic net loss per share attributable to common stockholders since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. The Company reported a net loss attributable to common stockholders for the three and six months ended June 30, 2022 and 2021. As the Merger has been accounted for as a reverse recapitalization, the condensed consolidated financial statements of the merged entity reflect the continuation of the pre-merger GreenLight financial statements; GreenLight equity has been retroactively adjusted to the earliest period presented to reflect the legal capital of the legal acquirer, ENVI. As a result, net loss per share was also retrospectively adjusted for periods ended prior to the Merger. See Note 3 for details and discussion of the retrospective adjustment of net loss per share. Comprehensive Loss Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. For the three and six months ended June 30, 2022 and 2021 , the Company had no items qualifying as other comprehensive loss; accordingly, comprehensive loss equaled net loss. Deferred Offering Costs As of December 31, 2021, the Company capitalized deferred offering costs of approximately $ 4.1 million. Deferred offering costs include certain legal, accounting, consulting and other third-party fees incurred directly related to the anticipated business combination. At the closing of the business combination during the first quarter of 2022, these previously deferred costs were recorded in stockholders’ equity as a reduction of additional paid-in capital. See Note 3 for further details of the Business Combination. Recently Issued Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , as subsequently amended (“Topic 842”), to improve financial reporting and disclosures about leasing transactions. This ASU requires companies that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases, where the lease terms exceed 12 months.
