Summary of Significant Accounting Policies | Note 2 - Summary of Significant Accounting Policies Basis of Presentation The condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). As a result of the Business Combination, for accounting purposes, ListCo is the acquirer and Legacy Adagio is the accounting acquiree and predecessor. The financial statement presentation includes the financial statements of Legacy Adagio as “Predecessor” for the periods prior to the Closing Date (the “Predecessor Period(s)”), and of the Company as “Successor” for the periods after the Closing Date (the “Successor Period(s)”), including the consolidation of Legacy Adagio and ARYA. The Successor Period includes the Company’s results of operations and cash flows for the period from July 31, 2024 through September 30, 2024. As a result of the application of the acquisition method of accounting as of the Closing Date of the Business Combination, the accompanying consolidated financial statements include a black line division that indicates that the Predecessor and Successor reporting entities shown are presented on a different basis and are therefore, not comparable. Unaudited Interim The accompanying interim condensed consolidated balance sheet as of September 30, 2024, the condensed consolidated statements of operations and comprehensive income (loss) and the condensed consolidated statements of convertible preferred stock and stockholders' equity (deficit), for the periods from July 1, 2024 to July 30, 2024 (Predecessor), July 31, 2024 to September 30, 2024 (Successor), January 1, 2024 to July 30, 2024 (Predecessor), July 31, 2024 to September 30, 2024 (Successor) and the three and nine months ended September 30, 2023 (Predecessor), and the condensed consolidated statements of cash flows for the periods from January 1, 2024 to July 30, 2024 (Predecessor), July 31, 2024 to September 30, 2024 (Successor), and nine months ended September 30, 2023 (Predecessor), and the related footnote disclosures are unaudited. These unaudited interim financial statements have been prepared in accordance with U.S. GAAP and, in management’s opinion, reflect all adjustments which only include normal recurring adjustments necessary for the fair presentation of the Company’s financial position as of September 30, 2024 (Successor) and its results of operations and comprehensive income (loss) for the periods from July 1, 2024 to July 30, 2024 (Predecessor), July 31, 2024 to September 30, 2024 (Successor), January 1, 2024 to July 30, 2024 (Predecessor), July 31, 2024 to September 30, 2024 (Successor), and the three and nine months ended September 30, 2023 (Predecessor), and cash flows for the periods from January 1, 2024 to July 30, 2024 (Predecessor), July 31, 2024 to September 30, 2024 (Successor), and nine months ended September 30, 2023 (Predecessor). The results for the periods from July 1, 2024 to July 30, 2024 (Predecessor), July 31, 2024 to September 30, 2024 (Successor), January 1, 2024 to July 30, 2024 (Predecessor) and July 31, 2024 to September 30, 2024 (Successor) are not necessarily indicative of the results to be expected for the year ending December 31, 2024, or any other interim period. Emerging Growth The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended, (the “Securities Act”), as modified by the Jumpstart our Business Startups Act of 2012 (the “JOBS Act”). Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when an accounting standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new standard at the time private companies adopt the new or revised standard. Principles of Consolidation The condensed consolidated financial statements include the accounts of Adagio Medical Holdings, Inc., and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates and Assumptions The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses and disclosures of contingent assets and liabilities. These estimates and assumptions are based on current facts, historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of revenue and expenses that are not readily apparent from other sources. Actual results could differ from those estimates. Segments Operating segments are defined as components of an entity for which separate financial information is available and that is 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’s CODM is its Chief Executive Officer. The Company has determined that it operates as one reportable segment, as the CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. Cash and Cash Equivalents The Company considers all highly liquid investments with maturities of three months or less from the date of purchase, including its money market account, to be cash equivalents. All of the Company’s cash equivalents have liquid markets. Cash deposits held in accounts at each United States financial institution are insured up to $0.25 million by the Federal Deposit Insurance Corporation (“FDIC”). Cash deposits held in accounts at each European Union financial institution are insured up to €0.1 million by the Deposit Guarantee Scheme. The Company maintains its cash in bank deposit accounts that, at times, may exceed the stated insured limits. Any loss incurred or lack of access to uninsured funds could have a significant adverse impact on the Company's financial condition, results of operations and cash flows. Management does not expect any losses on such accounts. Concentrations Financial instruments that potentially subject the Company to credit risk consist principally of cash and cash equivalents. The Company deposits its cash and cash equivalents with major financial institutions; however, at times, deposits may exceed the amount of insurance provided. The Company has not experienced any losses on its deposits since inception. Revenue Recognition The Company generates product revenue primarily from the sale of cryoablation catheters, stylets, esophageal warming balloons, and other accessories (collectively, the “Consumables”) used with the Company’s cryoablation consoles (“Consoles”). The Company sells its products directly to hospitals and medical centers. To a lesser extent, the Company also generates lease revenue from the implied rental of Consoles loaned to customers at no charge. The Company accounts for revenue earned from contracts with customers under ASC 606, Revenue from Contracts with Customers (“ASC 606”). The core principle of ASC 606 is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The Company recognizes revenue from sales to customers applying the following five steps: • • • • • The Company’s customer contracts generally have performance obligations that contain deliverables consisting of the Consumables and may also include Consoles loaned to customers. The Company evaluates each promise within a multiple-performance obligation arrangement to determine whether it represents a distinct performance obligation. The primary performance obligations in the Company’s customer arrangements from which it derives revenue is the sale of the Consumables. When the Company loans the Console to the customer, it retains title to the Console at all times and does not require minimum purchase commitments from the customer related to any Consumables. In such cases, the Company invoices the customer for the Consumables based on customer orders received. Over time, the Company expects to recover the cost of the loaned Console through the customer’s continued purchasing and use of additional Consumables. For these reasons, the Company has determined that part of the arrangement consideration for the Consumables is an implied rental payment for use of the Console. Therefore, the Company allocates the arrangement consideration between the lease components (i.e., the Console) and non-lease components (i.e., the Consumables) based on the relative estimated standalone selling price of each distinct performance obligation consistent with ASC 842, Leases and ASC 606. Revenue allocated to the lease components was not material for the periods from January 1, 2024 to July 30, 2024 (Predecessor), from July 31, 2024 to September 30, 2024 (Successor) and the nine months ended September 30, 2023 (Predecessor). Revenue from sales to customers of the Consumables is classified as revenue in the Company's condensed consolidated statements of operations and comprehensive income (loss). The delivery of the Consumables are performance obligations satisfied at a point in time, when the control of the goods is transferred to the customer (i.e., FOB Shipping Point). Revenue is recognized when control is transferred to the customer in an amount that reflects the consideration the Company expects to be entitled to in exchange for the product. Other Revenue Considerations Revenue is reported net of sales tax. The Company has made the accounting policy election not to recognize a separate performance obligation for the shipment of products to the customer but to account for it as fulfillment cost. The Company’s contracts primarily include fixed consideration. The Company only includes estimated variable amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Customers are generally required to pay within 30 days. Any incremental costs to obtain contracts are recorded as selling, general and administrative expense as incurred due to the short duration of the Company’s contracts. The Company does not assess whether promised goods or services are performance obligations if they are deemed immaterial in the context of the contract with the customer. Additionally, the Company does not assess whether a contract has a significant financing component if the expectation at contract inception is that the period between payment by the customer and the transfer of the promised goods or services to the customer will be one year or less. For the periods from January 1, 2024 to July 30, 2024 (Predecessor), from July 31, 2024 to September 30, 2024 (Successor), and nine months ended September 30, 2023 (Predecessor), revenue was generated only from European markets. Inventory Inventory consists of raw materials, work-in-process, and finished products and is valued at the lower of cost or net realizable value. The method by which that amounts are removed from the inventory is first-in first-out (“FIFO”). Cost may include materials, labor, and manufacturing overhead. The carrying value of inventory is reviewed for potential impairment whenever indicators suggest that the cost of inventory exceeds the carrying value and management adjusts the inventory to its net realizable value. The Company also periodically evaluates inventory for estimated losses from excess quantities and obsolescence and writes down the cost of inventory to net realizable value at the time such determinations are made. Net realizable value is determined using the estimated selling price, in the ordinary course of business, less estimated costs to complete and dispose. Inventory used in research and development activities is expensed when incurred. Property and Equipment Property and equipment are recorded at cost, less accumulated depreciation. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the related assets, generally three Property and equipment include equipment that is loaned to customers and located at customer premises. The Company retains ownership of the equipment held for evaluation by customers and has the right to remove the equipment if it is not being utilized according to expectations. Intangible Indefinite-lived intangible assets consist of In-Process Research and Development (“IPR&D”). Intangible assets with indefinite lives are tested for impairment if impairment indicators arise and, at a minimum, annually. However, an entity is permitted to first assess qualitative factors to determine if a quantitative impairment test is necessary. Further testing is only required if the entity determines, based on the qualitative assessment, that it is more likely than not that an indefinite-lived intangible asset’s fair value is less than its carrying amount. Otherwise, no further impairment testing is required. The indefinite-lived intangible asset impairment test consists of a one-step analysis that compares the fair value of the intangible asset with its carrying amount. If the carrying amount of an intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. No impairment charges were recorded in the period from July 31, 2024 to September 30, 2024 (Successor). Legacy Adagio does not have material intangible assets. Goodwill In accordance with ASC 350, Intangibles – Goodwill and Other, the Company tests goodwill for impairment at the reporting unit level. The Company has one reporting unit for the goodwill impairment testing purposes. Goodwill is tested for impairment on an annual basis in the fourth quarter, or more frequently if events or changes in circumstances indicate the carrying value of goodwill may not be recoverable (a “triggering event”). On the occurrence of a triggering event, an entity has the option to first assess qualitative factors to determine whether a quantitative impairment test is necessary. If it is more likely than not that goodwill is impaired, the fair value of the reporting unit (the Company) is compared with its carrying value. An impairment charge is recognized for the amount by which the carrying amount exceeds the fair value, provided, the loss recognized cannot exceed the total amount of goodwill. No goodwill impairment charges were recorded in the period from July 31, 2024 to September 30, 2024 (Successor). Legacy Adagio does not have goodwill. Concentrations The Company had three suppliers each exceed 10.0% of total accounts payable as of September 30, 2024 (Successor), representing 74.5% of accounts payable. As of December 31, 2023 (Predecessor), Legacy Adagio has three suppliers each exceed 10.0% of total accounts payable, representing 71.6% of accounts payable. The Company’s five and ten largest suppliers accounted for approximately 59.8% and 80.8%, respectively, of the Company’s expenditures for the periods from January 1, 2024 to July 30, 2024 (Predecessor) and July 31, 2024 to September 30, 2024 (Successor). Legacy Adagio’s five and ten largest suppliers accounted for approximately 39.4% and 50.5%, respectively, of Legacy Adagio’s expenditures for the nine months ended September 30, 2023 (Predecessor). Impairment The Company reviews long-lived assets, including property and equipment and finite-lived intangible assets, for impairment annually or whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. An impairment loss is recognized when the asset’s carrying value exceeds the total undiscounted cash flows expected from its use and eventual disposition. The amount of the impairment loss is determined as the excess of the carrying value of the asset over its fair value. For the periods from January 1, 2024 to July 30, 2024 (Predecessor), from July 31, 2024 to September 30, 2024 (Successor), and the nine months ended September 2023 (Predecessor), the Company determined that there was no impairment of long-lived assets. Foreign Currency Translation The assets, liabilities, and results of operations of Adagio Medical GmbH are recorded using the Euro as the designated functional currency, which is the currency of the primary economic environment in which Adagio Medical GmbH operates. Consequently, transactions in currencies other than Euro are measured and recorded in Euro. Upon consolidation with the Company, its assets and liabilities are translated to U.S. Dollars at currency exchange rates as of the condensed consolidated balance sheet date and its revenues and expenses are translated at the weighted-average currency exchange rates during the applicable reporting periods. Translation adjustments resulting from the process of translating this entity’s financial statements are reported in accumulated other comprehensive income (loss) in the condensed consolidated balance sheets and foreign currency translation adjustment in the condensed consolidated statements of operations and comprehensive income (loss). Leases The Company accounts for its lease property under ASC 842. Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases, and are recorded on the condensed consolidated balance sheets as both a right-of-use asset and a lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate, which is the rate for collateralized borrowings based on the current economic environment, current borrowings, value of leases, currency in which the lease obligation is satisfied, rate sensitivity, lease term and materiality. Lease liabilities are increased by interest and reduced by payments each period, and the right-of-use asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right-of-use asset results in straight-line rent expense over the lease term. Variable lease expenses are recorded when incurred. The Company determines whether a contract is or contains a lease at the inception of the contract. A contract will be deemed to be or contain a lease if the contract conveys the right to control and direct the use of identified property, plant, or equipment for a period of time in exchange for consideration. The Company generally must also have the right to obtain substantially all of the economic benefits from the use of the property, plant, and equipment. The Company uses the implicit rate in the lease agreement, when readily available, or its incremental borrowing rate as the basis to calculate the present value of future lease payments at lease commencement. The incremental borrowing rate represents the rate the Company would have to pay to borrow funds on a collateralize basis over a similar term and in a similar economic environment. In calculating the right-of-use asset and lease liability, the Company elected to combine lease and non-lease components for its real estate leases. The Company adopted the policy election to exclude short-term leases having initial terms of twelve months from the initial recognition provisions of ASC 842. Refer to Note 11- Operating Leases The Company's implied rental agreements for its consoles qualify as operating leases and as such, revenue is recognized in accordance with ASC 842, Leases and ASC 606, Revenue from Contracts with Customers. Revenue allocated to the lease components were not significant for the periods from January 1, 2024 to July 30, 2024 (Predecessor), from July 31, 2024 to September 30, 2024 (Successor), and nine months ended September 30, 2023 (Predecessor). Cost of Revenue Cost of revenue includes raw materials, direct labor, manufacturing overhead, shipping and receiving costs and other less significant indirect costs related to the production of the Company’s products. Cost of revenue also includes the depreciation expense of Consoles loaned to the customers. Research and Development Research and development expenses consist primarily of salaries, consulting fees, and employee-related costs (including stock-based compensation) for personnel directly engaged in research and development activities, clinical trial expenses, equipment costs, material costs, allocated rent and facilities costs, and depreciation. Research and development expenses relating to possible future products are expensed as incurred. The Company also accrues and expenses costs for activities associated with clinical trials performed by third parties as incurred. Selling, General and Administrative Selling, general and administrative expenses consist primarily of salaries, and employee-related costs (including stock-based compensation) for personnel in executive, finance and other administrative functions, allocated rent and facilities costs, legal fees relating to intellectual property and corporate matters, professional fees for accounting and consulting services, marketing costs and insurance costs. The Company expenses all selling, general, and administrative costs as incurred. The incurred transaction costs are recorded in selling, general, and administrative costs. Accrued Transaction Costs (Predecessor) In connection with the Business Combination, Legacy Adagio accrued transaction costs, consisting primarily of legal, accounting and other professional fees, which were incurred and expensed, but not yet paid. The accrued expenses as of December 31, 2023 (Predecessor) are recorded in accrued transaction costs on the condensed consolidated balance sheets. Fair Value Fair value measurements are based on the premise that fair value is an 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 such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the following three-tier fair value hierarchy is used in determining the inputs for measuring fair value: • • • Financial instruments measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Management’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. The use of different assumptions and/or estimation methodologies may have a material effect on estimated fair values. Accordingly, the fair value estimates disclosed, or initial amounts recorded may not be indicative of the amount that the Company or holders of the instruments could realize in a current market exchange. The fair value of the convertible notes payable and warrant liabilities may be impacted by certain unobservable inputs, most significantly with regard to discount rates, expected volatility and historical and projected performance. Significant changes to these inputs in isolation could result in a significantly different fair value measurement. Fair Value Option As permitted under ASC 825, Financial Instruments (“ASC 825”), Legacy Adagio elected the fair value option to account for the convertible promissory notes issued in October 2022 (the “October 2022 Convertible Notes”), April 2023 (the “April 2023 Convertible Notes”), November 2023 (the “November 2023 Convertible Notes”), February 2024 (the “February 2024 Convertible Notes”, “2024 Bridge Financing Notes”), May 2024 (the “May 2024 Convertible Notes”), June 2024 (the “June 2024 Convertible Notes”), and July 2024 (the “July 2024 Convertible Notes”) (collectively, “Legacy Adagio Convertible Notes”), and the Company elected the fair value option to account for the Convertible Securities Notes (as defined below), in order to measure those liabilities at amounts that more accurately reflect the current economic environment in which the Legacy Adagio and the Company operated. The convertible promissory notes mentioned above were recorded at fair value at issuance and subsequently were remeasured to fair value at the end of each reporting period. The change in fair value of the convertible promissory notes, excluding amounts related to interest, is recorded in “Convertible notes fair value adjustment”, while amounts related to interest are recorded as interest expense in the consolidated statements of operations and comprehensive income (loss). As a result of applying the fair value option, direct costs and fees related to the issuance of the convertible promissory notes were expensed as incurred (i.e., not recognized as deferred costs). Refer to Note 4- Fair Value Measurements Warrants The Company has Convert Warrants (as defined below) issued along with the Convertible Securities Notes, and PIPE Pre-funded Warrants (as defined below) issued in PIPE Financing (as defined below), which are classified as liabilities. The Company also has PIPE Base Warrants (as defined below) issued in PIPE Financing, which is classified as equity. Legacy Adagio has certain common stock warrants (“SVB Warrants”) issued along with the SVB Term Loan (as defined below) and pre-funded warrants to purchase Series E preferred stock (“Series E Pre-funded Warrants”), which were both classified as liabilities. The Company and Legacy Adagio determine the classification of warrants based on an assessment of the warrant’s specific terms and applicable authoritative guidance in ASC 480 and ASC 815. The assessment considers whether the warrants are freestanding financial instruments and meet all of the requirements for equity classification, including whether the warrants are indexed to the Company’s own shares of common stock, among other conditions for equity classification. This assessment is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding. For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter until settlement. Changes in the estimated fair value of the liability-classified warrants are recognized in warrant liabilities fair value adjustment in the condensed consolidated statements of operations and comprehensive income (loss). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is reassessed at the end of each reporting period. Equity instruments that are initially classified as equity that become subject to reclassification are reclassified to a liability at the fair value of the instrument on the reclassification date. Derivative instrument liabilities are classified in the condensed consolidated balance sheets as current or non-current based on whether or not net-cash settlement of the derivative instrument could be required within twelve months of the condensed consolidated balance sheet date. See Note 10- Warrants Term Loan (Predecessor) The Company accounts for the Predecessor term loan at residual value on the date of issuance. The expected life of the term loan is the contractual term ending on the maturity date. The Company classifies the term loan as current liabilities within twelve months of the maturity date or when otherwise due. Interest expense is recognized in the condensed consolidated statements of operations and comprehensive income (loss) over the contractual term of the loan. See Note 9- Debt Convertible Preferred Stock (Predecessor) The Company records the Legacy Adagio convertible preferred stock at fair value on the dates of issuance, net of issuance costs. Upon the occurrence of certain events that are outside the Legacy Adagio’s control, including a deemed liquidation event, holders of the convertible preferred stock can cause redemption for cash. Each share of preferred stock would automatically be converted into shares of Legacy Adagio common stock at the then effective conversion rate immediately upon the earlier of (i) the election of the holders of a majority of the outstanding shares of preferred stock, voting as a separate class on an as-converted to common stock basis, or (ii) the closing of the sale of the Legacy Adagio’s common stock in a firm commitment, underwritten public offering registered under the Securities Act of 1933, as amended, with aggregate offering proceeds to Legacy Adagio (before deduction for underwriters’ discounts and expenses relating to the issuance) of at least $75.0 million and a public offering price per share equal to at least $67.83 (subject to adjustments for stock dividends, splits, combinations and similar events). As the Legacy Adagio preferred stock is considered to be contingently redeemable, the Legacy Adagio preferred stock has been classified outside of permanent equity. Stock-Based Compensation The Company recognizes compensation expense for all stock-based awards issued to employees and non-employees based on the estimated grant-date fair value, which is recognized as expense on a straight-line basis over the requisite service period. The Company has elected to recognize forfeitures as they occur. The fair value of stock options is determined using the Black-Scholes option-pricing model. The determination of fair value for stock-based awards on the date of grant using an option-pricing model requires management to make certain assumptions including expected volatility, expected term, risk-free interest rate and expected dividends in addition to the Company’s common stock valuation. Refer to Note 14- Stock-Based Compensation Due to the absence of an active market for Legacy Adagio common stock, the Company utilized methodologies, approaches, and assumptions consistent with the American Institute of Certified Public Accountants Audit and Accounting Practice Aid Series: Valuation of Privately Held Company Equity Securities Issued as Compensation to estimate the fair value of Legacy Adagio common stock. In determining the exercise prices for options granted, the Company considered the fair value of the common stock as of the grant date. The fair value of the common stock is determined based upon a variety of factors, including the Company’s financial position, historical performance and operating results, the Company’s stage of development, the progress of the Company’s research and development programs, the prices at which the Company sold its convertible preferred stock, the superior rights, preferences and privileges of the Company’s convertible preferred stock relative to its common stock, external market conditions affecting the medical technologies industry, the lack of marketability of |
