| Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or U.S. GAAP. Principles of Consolidation The consolidated financial statements include the accounts of SpringWorks Therapeutics, Inc. and its subsidiaries, collectively, the Company. All intercompany transactions and balances have been eliminated in consolidation. Investments in business entities in which the Company lacks control but does have the ability to exercise significant influence over operating and financial policies are accounted for using the equity method of accounting. 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 in the financial statements and accompanying notes. Significant estimates and assumptions reflected in these consolidated financial statements include, but are not limited to, accrued research and development expenses and the valuation of equity-based compensation awards. The Company bases its estimates on historical experience, known trends and other market-specific or relevant factors that it believes to be reasonable under the circumstances. Actual results may differ from those estimates. On an ongoing basis, management evaluates its estimates, and adjusts those estimates and assumptions when facts or circumstances change. Changes in estimates are recorded in the period in which they become known. Segment Information Operating segments are defined as components of an entity about which separate discrete information is available for evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company views its operations and manages its business in one operating segment. Cash and Cash Equivalents The Company considers all highly liquid instruments that have maturities of three months or less when acquired to be cash equivalents. The Company had cash and cash equivalents as of December 31, 2023 and December 31, 2022 of $176.1 million and $67.5 million, respectively. Marketable Securities Marketable debt securities are reported at fair value with unrealized gains and losses included in accumulated other comprehensive income. Each reporting period, the Company evaluates whether there are declines in fair value below amortized cost and if these declines are due to credit losses, as well as the Company’s ability and intent to hold the investment until a forecasted recovery occurs. If both criteria regarding the intent or ability to hold are met, any decline in fair value due to credit losses is recorded as an allowance through other income (expense); limited by the amount that the fair value is less than the amortized costs basis. If either criterion is not met, any previously recorded allowance for credit losses and any excess amortized cost basis over fair value is recorded in other income (expense). As of, and for the years ended December 31, 2023 and December 31, 2022, the Company did not have any allowance for credit losses or impairments of its marketable securities. Concentration of Credit Risk Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, cash equivalents and available-for-sale marketable securities. The Company maintains each of its cash, cash equivalent balances and marketable securities balances with high quality, financial institutions and the Company’s marketable securities are invested in high-quality, highly liquid debt securities including corporate debt securities, U.S. government securities and commercial paper. Accounts Receivable, net Accounts receivable, net consists of trade receivables which are amounts due from customers related to product sales. The Company records trade receivables net of chargebacks, invoice discounts, distribution service fees and any allowances for potential credit losses. An allowance for credit losses is determined based on the financial condition and creditworthiness of customers and the Company considers economic factors and events or trends expected to affect future collections experience. Any allowance would reduce the net receivables to the amount that is expected to be collected. The payment history of the Company’s customers will be considered in future assessments of collectibility as these patterns are established over a longer period of time. As of December 31, 2023, the Company determined an allowance for credit losses was insignificant. Inventory and Pre-Approval Inventory The Company began capitalizing inventory for OGSIVEO upon approval by the FDA in November 2023. OGSIVEO is approved for the treatment of adult patients with desmoid tumors. Prior to regulatory approval, all direct and indirect manufacturing costs were charged to research and development expense in the period incurred. Inventory is comprised of raw materials, work-in-process and finished goods, and includes costs related to third-party contract manufacturing, packaging, freight-in and overhead. Inventory is stated at the lower of cost or net realizable value with cost based on the first-in-first-out method. Property and Equipment Property and equipment consist of computer equipment, software, furniture and leasehold improvements and are recorded at cost. Property and equipment are depreciated on a straight-line basis over their estimated useful lives. Intangible Asset, net The Company’s finite-lived intangible asset resulted from the capitalization of a milestone payment due under a license and collaboration agreement in connection with the first commercial sale of OGSIVEO in the United States in December 2023. The intangible asset will be amortized on a straight-line basis over its remaining useful life, which is estimated to be the remaining patent life of OGSIVEO. Amortization expense is recorded as cost of product revenue in the consolidated statement of operations. Impairment of Long-Lived Assets The Company reviews its long-lived assets, including property and equipment and finite-lived intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. If such circumstances are determined to exist, an estimate of undiscounted future cash flows produced by the long-lived asset, including its eventual residual value, is compared to the carrying value to determine whether impairment exists. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the asset, the asset is written-down to its estimated fair value. Revenue Recognition Arrangements Within the Scope of ASC 606, Revenue from Contracts with Customers The Company recognizes revenue in accordance with ASC 606, which applies to all contracts with customers, except for contracts that are within the scope of other standards, such as collaboration arrangements and leases. Pursuant to ASC 606, the Company recognizes revenue when its customers obtain control of promised goods or services, in an amount that reflects the consideration which the Company determines it expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligation(s) in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligation(s) in the contract; and (v) recognize revenue when (or as) the Company satisfies its performance obligation(s). As part of the accounting for these arrangements, the Company may be required to make significant judgments, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each performance obligation. Once a contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within the contract and determines those that are performance obligations. The Company assesses whether each promised good or service is distinct for the purpose of identifying the performance obligations in the contract. This assessment involves subjective determinations and may require management to make judgments about the individual promised goods or services and whether such are separable from the other aspects of the contractual relationship. Promised goods and services are considered distinct provided that: (i) the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer (that is, the good or service is capable of being distinct) and (ii) the entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract (that is, the promise to transfer the good or service is distinct within the context of the contract). In assessing whether a promised good or service is distinct, the Company considers factors such as the research, manufacturing and commercialization capabilities of the customer and the availability of the associated expertise in the general marketplace. The Company also considers the intended benefit of the contract in assessing whether a promised good or service is separately identifiable from other promises in the contract. If a promised good or service is not distinct, an entity is required to combine that good or service with other promised goods or services until it identifies a bundle of goods or services that is distinct. If the consideration promised in a contract includes a variable amount, the Company estimates the amount of consideration to which it will be entitled in exchange for transferring the promised goods or services to a customer. The Company determines the amount of variable consideration by using the expected value method or the most likely amount method. The Company includes the unconstrained amount of estimated variable consideration in the transaction price. The amount included in the transaction price is constrained to the amount for which it is probable that a significant reversal of cumulative revenue recognized will not occur. At the end of each subsequent reporting period, the Company re-evaluates the estimated variable consideration included in the transaction price and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis in the period of adjustment. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) each performance obligation is satisfied at a point in time or over time, and if over time based on the use of an output or input method that most faithfully depicts the transfer of goods and services to the customer. Product revenue, net: Revenues from product sales are recorded at the net sales price, or “transaction price,” which includes estimates of variable consideration that result from (i) invoice discounts for prompt payment and specialty distributor and specialty pharmacy service fees, (ii) government and other rebates, chargebacks, discounts and fees, (iii) group purchasing organization (“GPO”) discounts, performance rebates and administrative fees, (iv) product returns and (v) costs of co-pay assistance programs for patients. Reserves are established for the estimates of variable consideration based on the amounts the Company expects to be earned or to be claimed on the related sales. The reserves are classified as reductions to accounts receivable, net or accrued expenses and other current liabilities. Where appropriate, the Company utilizes the expected value method to determine the appropriate amount for estimates of variable consideration based on factors such as current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying, payment patterns and the Company’s historical experience. The amount of variable consideration that is included in the transaction price may be constrained and is included in net product revenues 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. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results vary from the Company's estimates, these estimates are adjusted, which would affect net product revenue and earnings in the period such variances become known. Licenses of intellectual property: The terms of the Company’s license agreements include the license of functional intellectual property, given the functionality of the intellectual property is not expected to change substantially as a result of the Company’s ongoing activities. For licenses that are bundled with other promises (that is, for licenses that are not distinct from other promised goods and services in an arrangement), the Company utilizes 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 for purposes of recognizing revenue. Up-front Fees: If a license agreement is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenues from the transaction price allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the license is deemed to be the predominant item and if the combined performance obligation is satisfied over time or at a point in time. Milestone Payments: At the inception of each arrangement that includes milestone payments (variable consideration), the Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments such as developmental and regulatory approval milestones, are generally not considered probable of being achieved until the related activity has been achieved, due to the uncertain nature of the success of clinical trials and obtaining regulatory approvals, which make it unlikely that a significant revenue reversal could be deemed not probable, until such time that the related event has occurred. Royalties: For arrangements that include sales-based royalties, including commercial milestone payments based on the level of sales, and 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 the royalty has been allocated has been satisfied (or partially satisfied). Reimbursement, cost-sharing and profit-sharing payments: Under certain arrangements, the Company has been reimbursed for a portion of its research and development expenses or participates in the cost-sharing of such research and development expenses. Such reimbursements and cost-sharing arrangements have been reflected in research and development expense in the Company’s consolidated statements of operations, as the Company does not consider performing research and development services for reimbursement to be a part of its ongoing major or central operations. Cost of Product Revenue Our cost of product revenue includes the cost of goods sold, amortization expense for commercial milestones and royalty expense. Our cost of goods sold consists of raw materials, third-party manufacturing costs to manufacture the raw materials into finished product, freight and other costs associated with sales of commercial products. Research and Development Expenditures for clinical development, including upfront licensing fees and milestone payments associated with products that have not yet been approved by the U.S. Food and Drug Administration, are charged to research and development expense as incurred. These expenses consist of expenses incurred in performing development activities, including salaries and benefits, equity-based compensation expense, preclinical expenses, clinical trial and related clinical manufacturing expenses, contract services and other outside expenses. Expenses incurred for certain research and development activities, including expenses associated with particular activities performed by contract research organizations, investigative sites in connection with clinical trials and contract manufacturing organizations, are recognized based on an evaluation of the progress or completion of specific tasks using either time-based measures or data such as information provided to the Company by its vendors on actual activities completed or costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of expense recognition. Expenses for research and development activities incurred that have yet to be invoiced by the vendors that perform the related activities are reflected in the consolidated financial statements as accrued expenses. Advance payments for goods or services to be received in the future for research and development activities are deferred and recorded as prepaid expenses. The prepaid amounts are expensed as the related goods are delivered or the services are performed. Selling, General and Administrative Selling, general and administrative expenses consist primarily of salaries and related costs, including equity-based compensation for personnel in executive, finance, corporate, commercial, business development and administrative functions. Selling, general and administrative expenses also include consulting services, legal fees relating to patent and corporate matters; professional fees for accounting, auditing and tax services; insurance costs; administrative travel expenses; and facility-related expenses, which include direct depreciation costs and expenses for rent and maintenance of facilities and other operating expenses. Equity-based compensation expense Equity-based compensation expense is recognized using the straight-line method, based on the grant date fair value, over the requisite service period of the award, which is generally the vesting term. The Company recognizes forfeitures at the time of the actual forfeiture event. For awards subject to performance conditions, as well as awards containing both market and performance conditions, the Company recognizes equity award compensation expense using an accelerated recognition method over the remaining service period when management determines that achievement of the milestone is probable. Management evaluates when the achievement of a performance-based milestone is probable based on the expected satisfaction of the performance conditions as of the reporting date. The grant-date fair value of performance-based awards with market conditions is estimated using a Monte Carlo simulation method that incorporates the probability of the performance conditions being met as of the grant date. For stock options issued, the Company estimates the grant date fair value and the resulting equity-based compensation expense using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires the use of certain subjective assumptions which determine the fair value of equity-based awards. Inputs used in the Black-Scholes option-pricing model are: • Fair value of common stock, which is the trading price of the Company’s common stock on the grant date of the award. • Expected term — The expected term represents the period that the equity-based awards are expected to be outstanding. The Company uses the simplified method to calculate the expected term due to the limited Company-specific historical information available for the Company. • Expected volatility — The Company lacks sufficient Company-specific historical and implied volatility information. Therefore, the Company includes the historical volatility of a publicly traded set of peer companies to determine its expected stock volatility and expects to continue to do so until it has adequate historical data regarding the volatility of its own traded stock. • Risk-free interest rate — The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of grant for zero-coupon U.S. Treasury notes with maturities approximately equal to the expected term of the awards. • Expected dividend — The Company has never paid dividends on its common units or stock and has no plans to pay dividends on its common stock. Therefore, the expected dividend yield is zero. Net Loss per Share Basic net loss per share is computed by dividing net loss by the weighted average number of shares outstanding for the period. Diluted net loss per share excludes the potential impact of unvested restricted stock and stock options because their effect would be anti-dilutive due to the Company’s net loss. Since the Company had a net loss in each of the periods presented, basic and diluted net loss per share are the same. Income Taxes Income taxes are accounted for using the asset-and-liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income in the period that includes the enactment date. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company recognizes deferred tax assets to the extent that it believes that these assets are more likely than not to be realized. In making such a determination, management considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies and results of recent operations. Valuation allowances are provided, if based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. If management determines that the Company would be able to realize its deferred tax assets in the future in excess of their net recorded amount, management would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) management determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, management recognizes the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. The Company provides reserves for potential payments of tax to various tax authorities related to uncertain tax positions. These reserves are based on a determination of whether and how much of a tax benefit taken by the Company in its filings or positions is more likely than not to be realized following resolution of any potential contingencies related to the tax benefit. Potential interest related to the underpayment of income taxes will be classified as a component of income tax expense and any related penalties will be classified as income tax expense. Recently Adopted and Recently Issued Accounting Pronouncements There were no recently adopted accounting pronouncements that had a material impact on the Company's financial statements. In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, to provide more detailed income tax disclosure requirements. The guidance requires entities to disclose disaggregated information about their effective tax rate reconciliation as well as information on income taxes paid. The disclosure requirements should be applied on a prospective basis, with the option to apply it retrospectively. The effective date for the standard is for fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company does not expect ASU 2023-09 to have a material impact on the Company's financial statements. |
