Notes to Condensed Consolidated Financial Statements

(unaudited)

Note 1 - Description of Organization and Business Operations

Our Company

Adagio Medical Holdings, Inc. (formerly known as Aja Holdco, Inc.), together with its wholly-owned subsidiaries (collectively, the "Company" or the "Successor"), is a medical technology company focused on the development and commercialization of ablation technologies for the treatment of cardiac arrhythmias. The Company is currently focused on the treatment of ventricular arrhythmias with its purpose-built vCLAS™ Cryoablation System, which is CE Marked and is currently under evaluation in the Company's FULCRUM-VT U.S. IDE Pivotal Study, which completed enrollment in October 2025. In April 2025, the Company received Breakthrough Device designation from the FDA for the Company's vCLASTM Cryoablation System for the treatment of drug-refractory, recurrent, sustained monomorphic ventricular tachycardia in patients with ischemic or non-ischemic structural heart disease. The Company's technologies are based on its proprietary ultra-low temperature cryoablation ("ULTC") platform, which is designed to produce durable, contiguous, transmural lesions anywhere in the heart using the Company's differentiated catheters and consoles. Legacy Adagio (as defined below) received CE Mark in Europe for its iCLAS™ Cryoablation System for atrial fibrillation and vCLASTM Cryoablation System for ventricular tachycardia ("VT") in June 2020 and March 2024, respectively. The Company is also currently developing a next-generation ULTC technology for VT, the design of which is faster, smaller and more flexible than its predecessor vCLAS device. This next generation device, which was designed to improve customer usability, requires only a single freeze. The Company has also developed pulsed field cryoablation ("PFCA"), a dual therapy platform technology that combines the Company's proprietary ultralow temperature technology with pulsed field ablation ("PFA"). The Company is headquartered in Laguna Hills, California.

On July 31, 2024 (the "Closing Date"), ARYA Sciences Acquisition Corp IV, a Cayman Islands exempted company ("ARYA"), Aja Holdco, Inc. ("ListCo"), a Delaware corporation and wholly-owned subsidiary of ARYA, Aja Merger Sub 1, a Cayman Islands exempted company and wholly-owned subsidiary of ListCo ("ARYA Merger Sub"), Aja Merger Sub 2, Inc., a Delaware corporation and wholly-owned subsidiary of ListCo ("Company Merger Sub"), and Adagio Medical, Inc., a Delaware corporation ("Legacy Adagio", the "Predecessor"), consummated the business combination (the "Business Combination") pursuant to the terms of the Business Combination Agreement, dated February 13, 2024, by and among the foregoing parties, as amended by the Consent and Amendment No. 1 to Business Combination Agreement, dated as of June 25, 2024, by and between ARYA and Adagio (the "Business Combination Agreement").

Pursuant to the Business Combination Agreement, on the Closing Date, (i) ARYA Merger Sub merged with and into ARYA (the "ARYA Merger") and Company Merger Sub merged with and into Legacy Adagio (the "Adagio Merger" and, together with the ARYA Merger, the "Mergers"), with ARYA and Legacy Adagio surviving the Mergers and, after giving effect to such Mergers, each of ARYA and Legacy Adagio becoming a wholly owned subsidiary of ListCo (the time that the ARYA Merger becomes effective being referred to as the "ARYA Merger Effective Time," the time that the Adagio Merger becomes effective being referred to as the "Adagio Merger Effective Time," the time after which both Mergers become effective being referred to as the "Closing," and the date on which the Closing occurs being referred to as the "Closing Date"), (ii) ListCo filed with the Secretary of State of the State of Delaware an amended and restated certificate of incorporation of ListCo, and the board of directors of ListCo approved and adopt amended and restated bylaws of ListCo, and (iii) ListCo changed its name to Adagio Medical Holdings, Inc.

Refer to Note 3 - Forward Merger for details of the Business Combination.

The Company's Common Stock (as defined below) began trading on the Nasdaq Capital Market on August 1, 2024, under the symbol "ADGM".

Liquidity and Going Concern

The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP" ) applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has limited revenue and has experienced recurring operating losses and negative cash flows from operations since its inception and anticipates that it will continue to do so for at least the next several years.

As of September 30, 2025, the Company had cash and cash equivalents of $4.7 million and an accumulated deficit of $92.3 million. For the three and nine months ended September 30, 2025 (Successor), and for the periods from July 31, 2024 to September 30, 2024 (Successor), and January 1, 2024 to July 30, 2024 (Predecessor), net (loss) income was $(10.1) million, $(21.8) million, $3.6 million, and $(21.3) million, respectively.

For the nine months ended September 30, 2025 (Successor), and for the periods from July 31, 2024 to September 30, 2024 (Successor), and January 1, 2024 to July 30, 2024 (Predecessor), net cash used in operating activities was $14.9 million, $6.4 million, and $16.0 million, respectively.

In October 2025, the Company announced a private placement of its common stock (or pre-funded warrants to purchase common stock in lieu thereof) and accompanying warrants to purchase shares of common stock, for aggregate gross proceeds of approximately $19 million (excluding up to $31 million of additional potential gross proceeds from the cash exercise of the common stock warrants) (the "Private Placement"). Refer to Note 19 - Subsequent Events for additional details.

Pursuant to ASC 205-40, Presentation of Financial Statements - Going Concern, the Company evaluates at each annual and interim reporting period whether conditions or events, considered in the aggregate, raise substantial doubt about its ability to continue as a going concern within one year after the date that the condensed consolidated financial statements are issued. As of the report date, the Company believes its existing cash and cash equivalents, including the proceeds received from the Private Placement, are sufficient to fund its operating and capital expenditure requirements for at least 12 months from the date of issuance of these unaudited interim condensed consolidated financial statements. If the Company's available cash and cash equivalents are insufficient to satisfy its liquidity requirements, the Company may need to raise additional capital to fund its operations. No assurance can be given as to whether additional needed financing will be available on terms acceptable to the Company, if at all. If sufficient funds on acceptable terms are not available when needed, the Company may be required to suspend or forego certain planned activities. Failure to manage discretionary spending or raise additional financing, as needed, would adversely impact the Company's ability to achieve its intended business objectives and have an adverse effect on its results of operations and future prospects.

Note 2 - Summary of Significant Accounting Policies

Basis of Presentation

These condensed consolidated financial statements have been prepared in accordance with 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").

Certain information and disclosures normally included in consolidated financial statements presented in accordance with U.S. GAAP have been condensed or omitted. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2024 (the "Annual Report") filed with the Securities and Exchange Commission, or SEC, on March 27, 2025.

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 periods from July 31, 2024, through September 30, 2025.

Unaudited Interim Financial Information

The accompanying unaudited interim condensed consolidated financial statements include the condensed consolidated balance sheet as of September 30, 2025 (Successor); the condensed consolidated statements of operations and comprehensive (loss) income and condensed consolidated statements of convertible preferred stock and stockholders' equity (deficit) for the three and nine months ended September 30, 2025 (Successor) and for the periods from July 31, 2024 to September 30, 2024 (Successor), July 1, 2024 to July 30, 2024 (Predecessor), and January 1, 2024 to July 30, 2024 (Predecessor); the condensed consolidated statements of cash flows for the nine months ended September 30, 2025 (Successor) and for the periods from January 1, 2024 to July 30, 2024 (Predecessor) and July 31, 2024 to September 30, 2024 (Successor); and the related footnote disclosures.

These unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") and, in management's opinion, include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the Company's financial position as of September 30, 2025 (Successor), and its results of operations and comprehensive income (loss) for the three and nine months ended September 30, 2025 (Successor), and for the periods from July 31, 2024 to September 30, 2024 (Successor) and January 1, 2024 to July 30, 2024 (Predecessor), and its cash flows for the nine months ended September 30, 2025 (Successor) and for the periods from July 31, 2024 to September 30, 2024 (Successor) and January 1, 2024 to July 30, 2024 (Predecessor).

The results for the three and nine months ended September 30, 2025 (Successor), and for the periods from July 31, 2024 to September 30, 2024 (Successor) and January 1, 2024 to July 30, 2024 (Predecessor), are not necessarily indicative of the results that may be expected for the year ending December 31, 2025, or for any other interim period.

Emerging Growth Company Status

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. 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 of Credit Risk and Off-Balance Sheet Risk

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 catheters (the "Consumables") used with the Company's 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:

•Step 1: Identify the contract with the customer.

•Step 2: Identify the performance obligations in the contract.

•Step 3: Determine the transaction price.

•Step 4: Allocate the transaction price to the performance obligations in the contract.

•Step 5: Recognize revenue when, or as, the Company satisfies a performance obligation.

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 three and nine months ended September 30, 2025 (Successor), and for the periods from January 1, 2024 to July 30, 2024 (Predecessor) and July 31, 2024 to September 30, 2024 (Successor).

Revenue from sales to customers of the Consumables is classified as revenue in the Company's condensed consolidated statements of operations and comprehensive 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 three and nine months ended September 30, 2025 (Successor) no revenue was recognized. For the periods from January 1, 2024 to July 30, 2024 (Predecessor) and from July 31, 2024 to September 30, 2024 (Successor), revenue was generated only from European markets.

Table of Contents

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 those amounts are removed from the inventory is first-in first-out. 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 to five years, or, in the case of leasehold improvements, over the remaining life of the lease term. Specifically, Consoles had a five-year useful life as of December 31, 2023, and effective on January 1, 2024, the useful life of Consoles was changed to three years to better reflect the estimated periods during which these Consoles will remain in service. The impact of the change in the estimated useful life of Consoles is not material to the Predecessor Periods or Successor Periods, nor to the future remaining life of the Consoles.

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 Assets

Intangible assets with finite useful lives are amortized on a straight-line basis over their estimated useful lives. In determining the estimated useful lives of definite-lived intangibles, the Company considers the nature, competitive position, life cycle position and expected future operating cash flows of the acquired asset, as well as its commitment to support these assets through continued investment and legal infringement protection.

The Company's intangible assets subject to amortization and other long-lived assets, are reviewed for impairment in accordance with ASC 360, Property, Plant and Equipment, which requires that companies consider whether events or changes in facts and circumstances, both internally and externally, may indicate that an impairment of long-lived assets held for use are present. The Company reviews long-lived assets for impairment at least annually or whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the asset, the assets are written down to their estimated fair value and the loss is recognized in the condensed consolidated statements of operations.

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 for the three and nine months ended September 30, 2025 (Successor) and for the period from July 31, 2024 to September 30, 2024 (Successor). Legacy Adagio did not have material intangible assets.

Table of Contents

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 for the three and nine months ended September 30, 2025 (Successor) and for the period from July 31, 2024 to September 30, 2024 (Successor). Legacy Adagio did not have any goodwill.

Concentrations

The Company had one supplier exceed 10% of total accounts payable as of September 30, 2025 (Successor), representing 45% of accounts payable. The Company had two suppliers exceed 10% of total accounts payable as of December 31, 2024 (Successor), representing 55% of accounts payable.

The Company's five and ten largest suppliers accounted for approximately 26% and 40%, respectively, of the Company's expenditures for the nine months ended September 30, 2025 (Successor).

The Company's five and ten largest suppliers accounted for approximately 60% and 81%, 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).

Impairment of Long-Lived Assets

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 nine months ended September 30, 2025 (Successor) and for the periods from January 1, 2024 to July 30, 2024 (Predecessor) and July 31, 2024 to September 30, 2024 (Successor), the Company determined that no impairment of long-lived assets was indicated.

Foreign Currency Translation and Transactions

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 loss in the condensed consolidated balance sheets and foreign currency translation adjustment in the condensed consolidated statements of operations and comprehensive (loss) income.

Table of Contents

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, 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 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 collateralized 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 or less from the initial recognition provisions of ASC 842. Refer to Note 11 - Operating Leases for additional details.

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. No revenue was allocated to the lease components for the three and nine months ended September 30, 2025 (Successor). Revenue allocated to the lease components was not significant for the periods from January 1, 2024 to July 30, 2024 (Predecessor) and July 31, 2024 to September 30, 2024 (Successor).

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 costs are expensed 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, corporate and financial matters, professional fees for accounting and consulting services, marketing costs and insurance costs. The Company expenses all selling, general, and administrative costs as incurred.

Fair Value Measurements

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:

•Level 1-Quoted prices in active markets for identical assets or liabilities.

Level 2-Observable inputs other than Level 1 prices for similar assets or liabilities that are directly or indirectly observable in the marketplace.

Level 3-Unobservable inputs which are supported by little or no market activity and consist of financial instruments valued using pricing models, discounted cash flow methodologies or similar techniques, as well as instruments for which the determination of fair value requires significant judgment or estimation.

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 for Convertible Notes

As permitted under ASC 825, Financial Instruments ("ASC 825"), Legacy Adagio elected the fair value option to account for the convertible securities 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", or the "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, 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 Securities 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 Securities Notes, including amounts related to interest, is recorded in "Convertible notes fair value adjustment".

As a result of applying the fair value option, direct costs and fees related to the issuance of the Convertible Securities Notes were expensed as incurred (i.e., not recognized as deferred costs). Refer to Note 4 - Fair Value Measurements for further detail.

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 the 2024 PIPE Financing (as defined below), which are classified as liabilities. The Company also has PIPE Base Warrants (as defined below) issued in the 2024 PIPE Financing, which are 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 classified as liabilities and 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 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.

Refer to Note 10 - Warrants for additional information related to the 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 (loss) income over the contractual term of the loan. Refer to Note 9 - Debt for additional information related to the term loan.

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 was considered to be contingently redeemable, the Legacy Adagio preferred stock was 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-Merton 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 the Legacy Adagio common stock, prospects of a transaction and market performance of peer companies. Significant changes to the key assumptions underlying the factors used could result in different fair values of Legacy Adagio at each valuation date.

Income Taxes

Income taxes are recorded in accordance with ASC 740, Income Taxes ("ASC 740"), 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 events that have been included in the condensed consolidated financial statements. Deferred tax assets and liabilities are determined based on the difference between the condensed consolidated financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse and include Net Operating Loss ("NOL") carryforwards and Research and Development ("R&D") tax credit carryforwards. 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.

The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740. When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit would more likely than not be realized assuming examination by the taxing authority. The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances.

ASU 2019-12, Simplifying the Accounting for Income Taxes, was adopted in the first quarter of 2021 and the Company has recorded franchise taxes not based on income outside of income tax expense. The Company's practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company had no accrual for interest or penalties on its condensed consolidated balance sheets and did not recognize any interest or penalties in its condensed consolidated statements of operations and comprehensive income (loss) for the nine months ended September 30, 2025 (Successor) and for the periods from January 1, 2024 to July 30, 2024 (Predecessor) and July 31, 2024 to September 30, 2024 (Successor), respectively.

To date, there have been no interest or penalties charged in relation to the unrecognized tax benefits. Refer to Note 16 - Income Taxes for additional details.

Acquisition Method of Accounting

The Business Combination has been accounted for as a forward-merger in accordance with U.S. GAAP. Under this method of accounting, ListCo has been treated as the "accounting acquirer" and Legacy Adagio as the "accounting acquiree" for financial reporting purposes. Accordingly, for accounting purposes, the Business Combination has been accounted for using the acquisition method of accounting. The acquisition method of accounting is based on ASC 805 and uses the fair value concepts defined in ASC 820. ASC 805 requires, among other things, that assets acquired, and liabilities assumed be recognized at their fair values as of the acquisition date, with limited exceptions per ASC 805-20-30-12 through 30-23. As such, under the acquisition method of accounting, ListCo's assets and liabilities retain their carrying amounts, and the assets and liabilities of Legacy Adagio, including any intangible assets recognized in connection with the Business Combination, are recorded at their fair values as of the acquisition date, except as otherwise required. The excess of the purchase price over the estimated fair values of net assets acquired is recorded as goodwill.

Under the acquisition method of accounting, ListCo was considered to be the accounting acquirer based on the terms of the Business Combination. Upon consummation of the Business Combination, the cash on hand resulted in the equity at risk being considered insufficient for Legacy Adagio to finance its activities without additional subordinated financial support. Therefore, Legacy Adagio was considered a Variable Interest Entity and the primary beneficiary of Legacy Adagio was treated as the accounting acquirer.

ListCo is the primary beneficiary of Legacy Adagio. ListCo holds 100% of the voting rights of Legacy Adagio and controls the Board of Directors of Legacy Adagio. Therefore, ListCo has the sole power to control the significant activities that impact Legacy Adagio's economic performance. ListCo's equity interest in Legacy Adagio results in the right to receive benefits and the obligation to absorb the losses of Legacy Adagio that could be significant to ListCo.

Goodwill represents the excess of the total purchase consideration over the fair value of the underlying net assets and captures the value attributable to future economic benefits arising from future technology development beyond the existing pipeline of identified IPR&D projects.

The acquired intangible assets consist of developed technology and IPR&D, which were valued at $26.2 million at the Closing using the cost approach. This approach considers an asset's replacement cost (direct and indirect) adjusted, where applicable, for obsolescence to estimate the replacement cost of the asset's current service potential (i.e., remaining useful life and cash-flow generating capacity). Obsolescence for an acquired intangible asset may include functional (technological) obsolescence and economic (external) obsolescence. The Company has determined the estimated useful life of five years for developed technology based on consideration of the economic benefit of the asset. Refer to Note 7- Goodwill and Intangible Assets for details.

In connection with the Business Combination, the transactions that occurred concurrently with the Closing Date of the Business Combination were reflected "on the line". "On the line" describes those transactions triggered by the consummation of the Business Combination that are not recognized in the consolidated financial statements of the Predecessor nor the Successor as they are not directly attributable to either period but instead were contingent on the Business Combination.

Note 4 - Fair Value Measurements

The Company's financial instruments include its money market accounts (included as part of cash and cash equivalents), accounts receivable, accounts payable, common stock warrant liabilities (i.e. Convert Warrants and SVB Warrants), pre-funded warrant liabilities (i.e. PIPE Pre-funded Warrants), and convertible notes payables (i.e. Convertible Securities Notes and Legacy Adagio Convertible Notes). The recorded carrying amounts of cash and equivalents, accounts receivable and accounts payable approximates fair value due to their short-term nature. The convertible notes, common stock warrant liabilities, and pre-funded warrant liabilities are carried at fair value.

Assets and liabilities recognized at fair value on a recurring basis in the condensed consolidated balance sheets consist of cash equivalents, common stock warrant liabilities, pre-funded warrant liabilities, and convertible notes payables. These items are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

In accordance with the agreement, ListCo issued on the Closing Date to the Convert Investors $20.0 million of Convertible Securities Notes and 1,500,000 Convert Warrants.

The $20.0 million Convertible Securities Notes are convertible into shares of the Company's common stock at a conversion price of $10.00 per share, subject to adjustment per the terms of the agreement. In the event of default, the Company may irrevocably elect in the event of default notice to permit the holder to effect alternate conversion, for which the conversion calculation and price are specified in the agreement.

The 1,500,000 Convert Warrants, each of which is exercisable on a cashless basis or for one share of the Company's common stock at $24.00 per share, subject to adjustment. The Convertible Securities Notes have a maturity of three years and nine months after the Closing and interest will be payable in cash or compound as additional principal outstanding which accrues on a quarterly basis. At the Company's option, payment of interest can either be (i) made quarterly in cash, or (ii) compound and become additional principal of the Convertible Securities Notes. As of September 30, 2025, the Company does not anticipate making a cash interest payment within the next 12 months.

The conversion of the February 2024 Convertible Notes was carried out on the same terms as the other Convert Investors executing the Convertible Security Subscription Agreement.

For the three and nine months ended September 30, 2025 (Successor), the Company recognized interest expense of $0.7 million and $2.1 million, respectively.

For the periods from July 31, 2024 to September 30, 2024 (Successor), the Company recognized interest expense of $0.4 million.

Note 10 - Warrants

SVB Warrants (Predecessor)

On February 3, 2023, in conjunction with the LSA, the Legacy Adagio issued Initial Warrants to purchase 32,720 shares of common stock of Legacy Adagio, and a contingent right to obtain an additional 16,360 shares of the common stock upon the non-occurrence of the Interest Only Milestone as mentioned above. The Additional Warrants are subject to the same terms as the Initial Warrants (collectively "SVB Warrants").

The exercise price of the SVB Warrants was $7.97 per share. The warrants were fully exercisable and would have expired on February 3, 2033.

The SVB Warrants were terminated prior to the consummation of the Business Combination as the fair market value of Legacy Adagio common stock is lower than the exercise price of the SVB Warrants before the Closing.

Series E Pre-funded Warrants (Predecessor)

On June 25, 2024, in conjunction with the Series E Preferred Stock exchange agreement (refer to Note 13 - Mezzanine Equity and Stockholders' Equity (Deficit)), Legacy Adagio issued to a certain investor 207,902 shares of pre-funded warrants to purchase 207,902 shares of Series E Preferred Stock, in exchange of the investor's existing holding of 207,902 shares of Series E Preferred Stock.

The exercise price of the pre-funded warrants was $0.001 per share. The pre-funded warrants were exercisable, at the option of the holder, on any day on or after the issuance date, in whole or in part. As an alternative to immediate cash payment, the investor could have elected to exercise the pre-funded warrant through a cashless exercise.

Upon the consummation of the Business Combination, the 207,902 Series E Pre-funded Warrants were converted in exchange for 34,680 shares of the Company's common stock.

Convert Warrants (Successor)

As mentioned in Note 9 - Debt, the Company issued $20.0 million of Convertible Securities Notes and 1,500,000 Convert Warrants at the Closing. Each of the Convert Warrants is exercisable on a cashless basis or for one share of the Company's common stock at an exercise price of $24.00 per share, subject to adjustment. The Convert Warrants expire on the seventh anniversary of the issuance date.

PIPE Pre-funded Warrants (Successor)

On the Closing Date, the Company issued 670,000 PIPE Pre-funded Warrants, along with 681,111 shares of the Company's common shares and 1,140,000 Base Warrants to certain Other PIPE Investors in exchange for cash proceeds of $9.5 million in 2024 PIPE Financing.

As set forth in the agreement of the PIPE Pre-Funded Warrants, the PIPE Pre-Funded Warrants are exercisable on a cashless basis or on a gross basis for one share of the Company's common stock at an exercise price of $0.01 per share, subject to adjustments. The Company may be required to cash settle the PIPE Pre-funded Warrants when it fails to timely deliver shares to the holder who exercises the PIPE Pre-funded Warrants or upon the occurrence of a fundamental transaction.

On December 26, 2024, 670,000 pre-funded warrant shares were exercised on a cashless basis for 663,096 shares of the Company's common stock. The exercise price for the pre-funded warrants was $0.9705 per share.

As of September 30, 2025, and December 31, 2024, there were no pre-funded warrants outstanding.

PIPE Base Warrants (Successor)

On the Closing Date, the Company issued 3,540,000 Base Warrants along with 4,372,607 shares of the Company's common shares to settle the outstanding principal and accrued interest of the Bridge Financing Notes.

37

Table of Contents

The Company also issued 3,345,069 Base Warrants along with 3,287,018 shares of the Company's common stock and 670,000 PIPE Pre-Funded Warrants to PIPE Investors for cash proceeds received in the 2024 PIPE Financing.

The Company issued 643,658 Base Warrants along with 761,229 shares of the Company's common stock in exchange for the non-redeemable 468,941 shares of ARYA's Class A ordinary shares held by certain Other PIPE Investors.

The Base Warrants can be exercised to the Company's common stock at any time during the period from the issuance date to the expiration date, which is the fifth anniversary from the date of issuance. The warrants can be exercised on a gross or net basis at an exercise price of $10 per share.

The Base Warrants were fair valued at $2.41 per unit on the date of issuance based on the assumptions including (i) the value of the Company's common stock is $6.64 per share; (ii) a risk-free rate at 3.93%; (iii) zero dividend yield; (iv) the common stock volatility at 84.0% and a volatility haircut of 10%; and (v) the remaining term is five years.

According to the ASC 815, it is determined that the Base Warrants associated with the 2024 PIPE Financing are indexed to the Company's common stock under and are accounted for as equity, which is initially measured at fair value. The Base Warrants are classified as equity in the financial statements because they meet the ASC 815-40 indexation guidance. Specifically, 1) the Base Warrants can be exercised at any time during the exercise period without contingencies; 2) the Base Warrants can be settled in a fixed number of shares upon exercise with any adjustments, such as antidilution and alternative issuance adjustments, consistent with ASC 815 guidance, which does not preclude equity classification. Additionally, the Company has sufficient authorized shares available to settle the Base Warrants, and all the adjustments are in the control of the Company, further supporting the equity classification.

The leases have expirations ranging from March 2026 to January 2030, some of which include rent escalations or an option to extend the lease for up to three years per renewal. The exercise of lease renewal options is at the sole discretion of the Company. Where leases contain an option to renew, any period beyond the option date is only included as part of the lease term if the Company is reasonably certain to exercise the option.

As of September 30, 2025 and December 31, 2024, the Company does not have any finance or short-term leases and has not entered into leases which have not yet commenced that would entitle the Company to significant rights or create additional obligations during the periods as of September 30, 2025 and December 31, 2024.

Note 13 - Mezzanine Equity and Stockholders' Equity (Deficit)

Authorized Shares (Predecessor)

Legacy Adagio's Amended and Restated Articles of Incorporation authorized the issuance of two classes of stock designated as common and preferred stock, each having a par value of $0.001 per share. The number of shares authorized as of July 30, 2024 was 11,534,892 consisting of 6,594,946 shares of common stock and 4,939,946 shares of preferred stock, designated as Series A, Series B, Series C, Series D, and Series E preferred stock in the amounts included in the table below.

Convertible Preferred Stock (Predecessor)

Legacy Adagio classified convertible preferred stock as temporary equity on the accompanying condensed consolidated balance sheets, as all such preferred stock was redeemable either at the option of the holder or upon an event outside the control of Legacy Adagio. The requirements of a deemed liquidation event, as defined within its amended and restated certificate of incorporation filed in November 2020, were not entirely within Legacy Adagio's control. In the event of such a deemed liquidation event, the proceeds from the event would have been distributed in accordance with the liquidation preferences, provided that the holders of preferred stock had not converted their shares into common stock. Legacy Adagio recorded the issuance of preferred stock at the issuance price less related issuance costs. Legacy Adagio had not adjusted the carrying value of outstanding preferred stock to its liquidation preference because a deemed liquidation event was not probable as of the end of the reporting period.

During the periods from January 1, 2024, to July 30, 2024 (Predecessor), the following transactions were executed:

On June 25, 2024, 207,902 shares of Series E Preferred Stock were extinguished and exchanged for 207,902 shares of pre-funded warrants to purchase Series E Preferred Stock. Refer to Note 10 - Warrants for additional information regarding the Series E Pre-funded Warrants. The difference between the carrying value of the extinguished Series E Preferred Stock and the fair value of the issued Series E Pre-funded Warrants was recorded in additional paid-in capital.

On the Closing Date, the Legacy Adagio's 4,732,044 convertible preferred stocks were converted into shares of Legacy Adagio common stock on a one-to-one basis prior to Adagio Merger Effective Time and then converted into 789,337 shares of the Company's common stock and additional paid-in capital at the Closing based on the exchange ratio set forth in the Business Combination Agreement.

There were no other preferred stock transactions during the year ended December 31, 2024 (Successor).

(1)The carrying value reflects the gross proceeds received from the sale of the preferred stock less issuance costs.

The relative rights, terms, privileges, and restrictions granted to or imposed upon preferred stockholders are described below:

Preferred Stock - Dividends

Prior and in preference to any declaration or payment of any dividends to the holders of common stock, the holders of preferred stock were entitled to receive dividends out of any assets legally available therefore, at the rate of eight percent (8%) of the original issue price per share per annum. The original issue price of Series A, Series B, Series C, Series D, and Series E was $9.23, $13.04, $16.30, $20.16, and $22.61, respectively. The dividends were not cumulative.

In the event that the dividend amount declared by the Board of Directors of Legacy Adagio was insufficient to permit payment of the full aforesaid dividends, such dividends would have been paid ratably to each holder of preferred stock in proportion to the dividend amounts to which each holder of preferred stock was entitled. After payment of the full amount of the aforesaid dividends, any additional dividends declared would have been distributed to the holder of common stock and preferred stock in proportion to the number of shares of common stock that were held by such holder on an as-converted to common stock basis.

No dividends on preferred stock or common stock had been declared by the Board of Directors as of July 30, 2024 (Predecessor) or as of the Closing date.

Liquidation Preference

In the event of liquidation of Legacy Adagio, including a merger, acquisition, or sale of all or substantially all the assets of Legacy Adagio, holders of preferred stock were entitled to receive an amount equal to the original issue price of each share of preferred stock held plus any dividends declared but not yet paid, prior to any distribution of assets or surplus funds of Legacy Adagio to common stock shareholders. After payment had been made to the holders of the preferred stock of the full amounts to which they were entitled as noted above, the remaining assets would have been distributed among the holders of the common stock pro rata based on the number of shares of common stock held by each holder.

If, at the time of liquidation, the assets were insufficient to permit full payment of the liquidation preferences of the series listed in the order above, the assets would have been distributed ratably among the holders of the series in proportion to the full preferential amount each such holder was otherwise entitled to receive in respect to such shares.

Table of Contents

Voting Rights

So long as the shares of preferred stock that were convertible into at least 1,000,000 shares of common stock (subject to appropriate adjustment in the event of any stock dividends, stock split, combination or other similar recapitalization with respect to the common stock) were issued and outstanding, the holders of preferred stock, voting as a separate class on an as-converted to common stock basis, had the right to elect four members of the Board of Directors of Legacy Adagio. The holders of common stock, voting as a separate class, had the right to elect one member of the Board of Directors. The remaining directors would be elected by the holders of the common stock and the preferred stock, voting together as a single class on an as-converted to common stock basis.

On all other matters, the holders of the preferred stock had full voting rights and powers equal to the voting rights and powers of the holders of common stock.

Fractional votes by the holders of preferred stock were not permitted and any fractional voting rights would be rounded to the nearest whole number.

Conversion Rights

Each share of preferred stock was convertible, at the option of the holder, into shares of common stock without the payment of any additional consideration. The preferred stock was convertible into the number of fully paid and nonassessable shares of common stock, which results from dividing the conversion price per share in effect for the preferred stock at the time of conversion into the per share conversion value. The initial per share conversion price of Series A, Series B, Series C, Series D, and Series E was $9.23, $13.04, $16.30, $20.16, and $22.61, respectively. The initial conversion price was subject to adjustment for antidilution provisions, as defined. The per share conversion value of Series A, Series B, Series C, Series D, and Series E was $9.23, $13.04, $16.30, $20.16, and $22.61, respectively.

Each share of preferred stock would automatically be converted into shares of 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 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 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).

Protective Provisions

So long as there were at least 1,000,000 shares of preferred stock outstanding, Legacy Adagio shall not (by merger, reclassification, amendment or otherwise), without first obtaining the approval of the holders of at least seventy percent (70%) of the then outstanding shares of preferred stock, voting separately as a class, to, among other things: (i) amend the certificate of incorporation or bylaws; (ii) adversely alter or change the rights, preferences or privileges of the preferred stock; (iii) increase or decrease the aggregate number of authorized shares of any class of the capital stock of Legacy Adagio.

So long as shares of Series E preferred stock that were convertible into at least 500,000 shares of common stock (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the common stock) were issued and outstanding, Legacy Adagio did not, directly or indirectly (by merger, reclassification, amendment or otherwise), without first obtaining the approval of the holders of at least a majority of the voting power of the then outstanding shares of Series E preferred stock, voting separately as a class, do, among other things: (i) amend, alter, repeal or waive any provision of the certificate of incorporation or bylaws of Legacy Adagio in a manner that adversely affected the holders of the Series E preferred stock in a manner different from any other series of preferred stock; (ii) create or authorize the creation of or issue any other security convertible into or exercisable for any equity security having rights, preferences or privileges senior to the Series E preferred stock; or (iii) increase or decrease the authorized number of shares of Series E preferred stock.

Table of Contents

Common Stock (Predecessor)

Prior to the Business Combination, each share of Legacy Adagio common stock was entitled to one vote. As of December 31, 2024 (Predecessor), Legacy Adagio was authorized to issue up to 6,594,946 of common stock at a par value of $0.001 per share out of which 786,510 shares were issued and 779,908 shares were outstanding.

On the Closing Date, as explained in Note 3 - Forward Merger, each share of Legacy Adagio issued and outstanding prior to the Closing Date was converted into the Company's common stock based on the exchange ratio set forth in the Business Combination Agreement.

Common Stock (Successor)

As of September 30, 2025 (Successor), the Company's certificate of incorporation, as amended and restated, authorized the Company to issue up to 210,000,000 of common stock at a par value of $0.0001 per share, and 20,000,000 shares of preferred stock, par value $0.0001 per share. As of September 30, 2025 (Successor), 15,381,565 shares were issued and outstanding, including 1,147,500 Sponsor Earnout (as defined below).

In September 2024, the Company issued 1,147,500 shares of the Company's Common Stock (such issuance, the "Sponsor Earnout") to the AYRA Sponsor under the Sponsor Letter Agreement dated February 13, 2024 ("the Sponsor Letter Agreement"). Pursuant to the agreement, the Sponsor Earnout shall be unvested and vests upon the earlier of: (i) During the period from the effective time to the 10th anniversary of the Closing Date (the "Earn-Out Period"), the stock price of the Company's Common Stock equals to or exceeds $24.00 per share for any 20 trading days within any 30 trading day period from and after the Closing Date and (ii) immediately prior to the consummation of a company sale during the Earn-Out Period.

As of the reporting date, the vesting of the Sponsor Earnout was not considered probable.

According to ASC 815, it is determined that the Sponsor Earnout is indexed to the Company's common stock and classified as equity and is initially measured at fair value and not subsequently remeasured. The Sponsor Earnout vests when the Company's stock price meets a stated price or there is a company sale during the earnout period. Upon meeting either vesting condition, the same number of the Company's common stock would be issued and no longer subject to forfeiture or cancellation. The Sponsor Earnout meets the ASC 815-40 indexation guidance. Specifically, the stated stock price and company sale, as the exercise contingencies, do not preclude equity indexation and there is no variability in the number of shares issuable under the Sponsor Earnout. Additionally, the Sponsor Earnout at the issuance meets the ASC 815-40 equity classification criterion as the Company has sufficient authorized shares available to settle the Sponsor Earnout and all the antidilution adjustments are in the control of the Company.

The holders of the Company's common stock are entitled to receive dividends whenever funds are legally available, when and if declared by the Company's Board of Directors. As of September 30, 2025 (Successor), no cash dividend has been declared to date. Each share of the Company's common stock is entitled to one vote.

Predecessor Periods

2012 Stock Incentive Plan

In January 2011, Legacy Adagio's Board approved the 2012 Stock Incentive Plan (the "2012 Plan"), which permitted grants of Incentive Stock Options ("ISOs") and Non-statutory Stock Options ("NSOs") to employees, directors and consultants. The maximum number of shares that can be granted under the 2012 Plan cannot exceed 1,255,000 shares. The 2012 Plan had a maximum 10-year term and as such, terminated in January 2022.

2022 Stock Incentive Plan

In April 2022, the Legacy Adagio's Board approved, in conjunction with the termination of the 2012 Plan, the 2022 Stock Incentive Plan (the "2022 Plan"), permitting ISOs and NSOs to employees, directors and consultants. The maximum number of shares granted under the 2022 Plan cannot exceed 203,855 plus any shares subject to stock options granted under the 2012 Plan that expired or were otherwise terminated without having been exercised in full, were forfeited, or were repurchased by the Company. The 2022 Plan is intended as the successor to and continuation of the 2012 Plan (thereafter both the 2012 and 2022 Plans are referred to as the "Stock Incentive Plan").

The Stock Incentive Plan provides a means whereby participants may purchase shares of common stock pursuant to ISOs or NSOs and such persons may be granted shares of common stock for consideration consisting of cash and/or past services rendered to or on behalf of Legacy Adagio. ISOs may only be granted to employees. NSOs and stock purchase rights may be granted to employees and consultants. Generally, options awards only have service conditions that need to be met for the awards to vest, with the exception of grants to two non-employees that had performance obligations that were deemed to be immaterial.

The stock options generally vest over four years and have a ten-year contractual term. The fair value of each employee and non-employee stock option grant is estimated on the date of grant using the Black-Scholes-Merton option pricing model. As Legacy Adagio lacks company-specific historical and implied volatility information required for valuation, Legacy Adagio estimates its expected stock volatility based on the historical volatility of a publicly traded set of peer companies. Due to the lack of historical exercise history, the expected life term of ISOs that were granted after 2013 was determined using the "simplified method" provided by the Securities and Exchange Commission in Staff Accounting Bulletins Number 107 and 110. The expected life term of NSOs is determined either by using the "simplified method," or by calculating the time to expiry from the grant date. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant for time periods approximately equal to the expected term of the award. Expected dividend yield is zero as Legacy Adagio has never paid nor does it expect to pay any cash dividend in the near future.

There were no stock options exercised during the periods from January 1, 2024 to July 30, 2024 (Predecessor). Certain stock option grants under the Stock Incentive Plan allow the recipient to exercise the options prior to the options becoming fully vested. Under the Stock Incentive Plan, the Company retains the right to repurchase common shares that have been issued upon early exercise of options at the original issue price. Cash received for the early exercise of unvested stock options is initially recorded as a liability. At each reporting date, the vested shares are released to equity.

The fair value of awards vested was $0.3 million during the periods from January 1, 2024 to July 30, 2024 (Predecessor). As of July 30, 2024 prior to the Closing (Predecessor), the total unrecognized compensation cost of $0.4 million was accelerated at the Closing, which was recognized and expensed in accordance with the terms of the 2012 Stock Incentive Plan and the 2022 Stock Incentive Plan.

Upon the consummation of the Business Combination, 45,544 In-the-Money Adagio Options were canceled and extinguished in exchange for 7,587 options to purchase the Company's common stock, and the 2022 Plan was terminated.

Successor Periods

2024 Equity Incentive Plan

The Board of Directors of the Company adopted the 2024 Equity Incentive Plan on July 26, 2024. The purpose of the 2024 Equity Incentive Plan is to promote the success and enhance the value of the Company by linking the individual interests of the members of the Board of Directors, employees, and consultants to those of Company stockholders and by providing such individuals with an incentive for outstanding performance to generate superior returns to Company stockholders. The 2024 Equity Incentive Plan authorizes the issuance of up to 4,472,593 shares of the Company's Common Stock, plus an annual increase on the first day of each year beginning in 2025 and ending in (and including) 2034 equal to the lesser of (A) five percent (5%) of the shares of Common Stock outstanding on a fully diluted basis on the last day of the immediately preceding fiscal year and (B) such smaller number of shares of Company's Common Stock as determined by the Board or the compensation committee thereof. Accordingly, on January 1, 2025, the number of shares of common stock available for issuance under the 2024 Equity Incentive Plan increased by 1,725,144 shares. The Company may grant an option, a stock appreciation right, a restricted stock award, a restricted stock unit award, a performance stock award, a performance stock unit award, or other stock- or cash-based award, or a dividend equivalent award, which may be awarded or granted under the 2024 Equity Incentive Plan. The awards can be issued to any person who is an employee, a consultant, or a non-employee director.

During the nine months ended September 30, 2025, the Company granted 5,687,965 awards under this plan.

2024 Key Employee Equity Incentive Plan

The Board of Directors of the Company adopted the 2024 Key Employee Equity Incentive Plan on July 26, 2024. The purpose of the 2024 Key Employee Equity Incentive Plan is to promote the success and enhance the value of the Company by linking the individual interests of key employees of the Company to those of Company stockholders and by providing such individuals with an incentive for outstanding performance to generate superior returns to Company stockholders. The 2024 Key Employee Equity Incentive Plan authorizes the issuance of up to 3,354,444 shares of the Company's Common Stock. The Company may grant option, a stock appreciation right, a restricted stock award, a restricted stock unit award, a performance stock award, a performance stock unit award, other stock- or cash-based award, or a dividend equivalent award, which may be awarded or granted under the plan.

The Company has not granted any awards under this 2024 Key Employee Equity Incentive Plan as of September 30, 2025.

2024 Employee Stock Purchase Plan

The Board of Directors of the Company adopted the 2024 Employee Stock Purchase Plan on July 26, 2024. The 2024 Employee Stock Purchase Plan provides a means by which eligible employees of the Company and certain designated related corporations may be given an opportunity to purchase shares of the Company's Common Stock. The 2024 Employee Stock Purchase Plan permits the Company to grant a series of purchase rights to eligible employees. The 2024 Employee Stock Purchase Plan authorizes the issuance of up to 441,293 shares of the Company's Common Stock, plus an annual increase on the first day of each year for the ten (10) calendar years immediately after the first Offering Date (as defined in the 2024 Employee Stock Purchase Plan) equal to one percent (1%) of the share of common stock outstanding on a fully diluted basis on the last day of the immediately preceding fiscal year, provided that the Board or its compensation committee may reduce the amount of the increase in any particular year.

The Company has not granted any purchase rights under this plan as of September 30, 2025.

Note 15 - Loss Per Share ("LPS")

Predecessor

Basic net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period. Diluted net loss per common share excludes the potential impact of the Company's convertible preferred stock, common stock warrants, and common stock options because the Company's net losses would cause such shares to be anti-dilutive. Therefore, as the Company recorded net losses in the periods presented, basic and diluted net loss per common share are the same.

Successor

After the Business Combination, the Successor calculated basic LPS and diluted LPS to common stockholders in conformity with the two-class method required for companies with participating securities. The Company considered (i) the Convertible Securities Notes and (ii) the earnout shares subject to vesting conditions to be participating securities as they participate in any distributions declared by the Company. The Company's Base Warrants and Convert Warrants are considered as non-participating securities, as the holders are not entitled to any shareholder right prior to the exercise of the Base Warrants and the Convert Warrants. As of the reporting date, none of the Base Warrants or the Convert Warrants were exercised to receive the Company's common stock.

Under the two-class method, undistributed earnings allocated to these participating securities are subtracted from net income in determining net income attributable to common stockholders. In periods of net loss, losses are allocated to the participating security only if the security has not only the right to participate in earnings, but also a contractual obligation to share in the Company's losses. As the Company incurred a net loss for the three and nine months ended September 30, 2025, the Convertible Securities Notes were not considered participating securities and were excluded from the two-class method calculation.

Further, Basic LPS under the two-class method includes the impact of the Company's PIPE Pre-funded Warrants as the PIPE Pre-funded Warrants are exercisable for only $0.01 per share (i.e., de minimis cash consideration) without an expiration date and not subject to exercise contingencies.

The Company discloses the Diluted LPS under the if-converted method as such diluted LPS is lower than the diluted LPS calculated under the two-class method. The Earn-Out shares subject to vesting conditions are not considered in the denominator for the calculation of diluted LPS as the vesting conditions for the Earn-Out shares were not met during the successor reporting period.

Note 16 - Income Taxes

The Company accounts for income taxes in accordance with ASC 740. Under the provisions of ASC 740, management is required to evaluate whether a valuation allowance should be established against its deferred tax assets. The Company currently has a full valuation allowance against its deferred tax assets. As of each reporting date, the Company's management considers new evidence, both positive and negative, that could impact management's view with regard to future realization of deferred tax assets. For the nine months ended September 30, 2025 (Successor) there was no material change from the fiscal year ended December 31, 2024 (Successor) in the amount of the Company's deferred tax assets that are not considered to be more likely than not to be realized in future years.

For the periods from January 1, 2024 to July 30, 2024 (Predecessor) and July 31, 2024 to September 30, 2024 (Successor), the effective tax rate for the Company's operations was 0.0%. The effective tax rate differed from the U.S. federal statutory rate primarily due to state income taxes, losses from the German subsidiary that is subject to different effective tax rates, stock-based compensation, fair value adjustments for convertible notes and warrant liabilities, and a change in the valuation allowance that offset the tax benefit on the current period pre-tax loss.

The Company is subject to U.S. federal income tax as well as income tax of foreign and state tax jurisdictions. The tax years 2020-2024 remain open to examination by the major taxing jurisdictions to which the Company is subject, except the Internal Revenue Service for which the tax years 2021-2024 remain open.

On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was enacted in the United States. The OBBBA includes significant changes, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to certain aspects of the international tax framework and the restoration of favorable tax treatment for certain business expense provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The Company has incorporated the provisions that were effective during the third quarter of 2025 and assessed that the impacts did not have a material impact on its condensed consolidated financial statements. The Company will continue to assess any future impacts on its condensed consolidated financial statements and will recognize the income tax effects beginning in the period in which they are effective.

Note 19 - Subsequent Events

On October 14, 2025, the Company entered into a Securities Purchase Agreement (the "Securities Purchase Agreement") with certain accredited healthcare investors (the "Purchasers") pursuant to which it issued and sold to the Purchasers in the Private Placement: (i) 9,792,506 shares (the "Shares") of its common stock, par value $0.0001 per share (the "Common Stock"), or pre-funded warrants (the "Pre-Funded Warrants") to purchase shares of Common Stock in lieu thereof, and (ii) accompanying (a) Tranche A Warrants to purchase an aggregate of 6,012,943 shares of Common Stock (or pre-funded warrants in lieu thereof) (the "Tranche A Warrants"), Tranche B Warrants to purchase an aggregate of 6,012,943 shares of Common Stock (or pre-funded warrants in lieu thereof) (the "Tranche B Warrants") and Tranche C Warrants to purchase an aggregate of 6,012,943 shares of Common Stock (or pre-funded warrants in lieu thereof) (the "Tranche C Warrants" and, together with the Tranche A and Tranche B Warrants, the "Milestone Warrants"), for aggregate gross proceeds of approximately $19 million (excluding up to approximately $31 million of aggregate gross proceeds that may be received in the future upon the cash exercise in full of the Milestone Warrants issued in the Private Placement), before deducting placement agent fees and other expenses payable by the Company. Each Share, or Pre-Funded Warrant in lieu thereof, sold pursuant to the Securities Purchase Agreement was accompanied by one Tranche A Warrant, one Tranche B Warrant and one Tranche C Warrant. The combined purchase price of each Share and accompanying Milestone Warrants is $1.9403 and (which includes $0.2303 for the Milestone Warrants sold with each Share in accordance with the rules and regulations of The Nasdaq Stock Market LLC). The combined purchase price of each Pre-Funded Warrant and accompanying Milestone Warrant is $1.9402 (equal to the combined purchase price per Share and accompanying Milestone Warrants, minus $0.0001). Entities affiliated with Perceptive Advisors LLC, an affiliate of the Company, purchased Pre-Funded Warrants and Milestone Warrants for an aggregate purchase price of $4,250,000.

Each Milestone Warrant is exercisable for one share of Common Stock at an exercise price of $1.71 per share. The Milestone Warrants will expire upon the earlier of (i) five years from the date of issuance or (ii) (a) for the Tranche A Warrants, the date that is thirty (30) days following its announcement of results from the Company's FULCRUM-VT IDE pivotal clinical trial, (b) for the Tranche B Warrants, the date that is thirty (30) days following its announcement of FDA approval of the vCLAS Cryoablation System, and (c) for the Tranche C Warrants, the date that is thirty (30) days following the Company's announcement of FDA approval of its second generation vCLAS catheter system. The Pre-Funded Warrants are exercisable for one share of Common Stock at an exercise price of $0.0001 per share. The Pre-Funded Warrants are immediately exercisable and may be exercised at any time until all of the Pre-Funded Warrants are exercised in full.

A holder (together with its affiliates) of the Pre-Funded Warrants or Milestone Warrants, as the case may be, may not exercise any portion of the Pre-Funded Warrants or Milestone Warrants to the extent that the holder would own more than 4.99% (or, at the holder's option upon issuance, 9.99%) of the Company's outstanding Common Stock immediately after exercise, which percentage may be changed at the holder's election to a lower or higher percentage not in excess of 19.99% upon 61 days' notice to the Company subject to the terms of the Pre-Funded Warrants or the Milestone Warrants. In lieu of making the cash payment otherwise contemplated to be made to the Company upon exercise of a Milestone Warrant, after the deadline for effectiveness of the registration statement to be filed pursuant to the Registration Rights Agreement, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of Common Stock determined according to a formula set forth in the Milestone Warrants, provided that such cashless exercise shall only be permitted if, at the time of such exercise, there is no effective registration statement registering the resale of shares of Common Stock underlying the Milestone Warrants or if the prospectus contained in such registration statement is not available for the resale of shares of Common Stock underlying the Milestone Warrants by the Milestone Warrant holder.

In lieu of making the cash payment otherwise contemplated to be made to the Company upon exercise of a Pre-Funded Warrant in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of Common Stock determined according to a formula set forth in the Pre-Funded Warrants.

On July 26, 2024, ARYA Sciences Acquisition Corp IV ("ARYA") held its annual general meeting at which the ARYA shareholders considered and adopted, among other matters, the Business Combination Agreement. On July 31, 2024, the parties to the Business Combination Agreement consummated the Business Combination.

ListCo was deemed the accounting acquirer in the Business Combination based on an analysis of the criteria outlined in Accounting Standards Codification 805, Business Combinations. Legacy Adagio is the accounting acquiree and predecessor based on an analysis of the criteria outlined in the Accounting Standards Codification 805, Business Combinations. Accordingly, the historical financial statements of Legacy Adagio became the historical financial statements of the combined company upon the consummation of the Business Combination. As a result, the financial statements included in this report reflect (i) the historical operating results of Legacy Adagio prior to the Closing; and (ii) the combined results of the Company following the Closing. The accompanying financial information includes a predecessor period, which includes the periods through July 30, 2024, concurrent with the Business Combination, and the successor period from January 1, 2025, through September 30, 2025.

Overview

We are a medical device company focused on developing and commercializing products for the treatment of cardiac arrhythmias with our novel, proprietary, catheter-based Ultra-Low Temperature Cryoablation ("ULTC") technology. Our initial focus is on the treatment of ventricular tachycardia ("VT"). VT is a rapid, abnormal heart rhythm, or arrhythmia, that originates in the heart's lower chambers, or ventricles, potentially leading to impaired blood flow and, if sustained, VT can be fatal. VT-associated sudden cardiac death ("SCD") accounts for approximately 300,000 deaths each year in the U.S. Radio Frequency ("RF") ablation catheters currently used to treat VT were primarily designed and approved for the treatment of atrial fibrillation ("AF") and are therefore not designed to optimally treat the specifics of the ventricular anatomy and disease. As a result, VT procedures performed with current devices can be overly complex and can lead to sub-optimal outcomes, factors that have potentially led to the limited growth in the market for VT ablations.

Our clinically tested, proprietary ULTC products are purpose-built to treat patients with VT and are designed to address the unique anatomy of the ventricle and the specific needs of the VT patient. Our ULTC approach is built on the hypothesis that large and durable lesions extending through the depth of both diseased and healthy muscular tissue of the ventricle of the heart (ventricular myocardium) is a foundation for improving the effectiveness of VT ablations and patient outcomes. Our differentiated catheters are designed for large, durable, deep lesions within the ventricle through an endocardial approach with no required irrigation. In October 2025, we announced completion of enrollment in our FULCRUM-VT Pivotal U.S. Food and Drug Administration ("FDA") Investigational Device Exemption ("IDE") study evaluating the vCLASTM Cryoablation System for ablation of monomorphic ventricular tachycardia (MMVT) in patients with both ischemic and nonischemic cardiomyopathy. The vCLAS System, which was granted Breakthrough Device Designation by the FDA in April 2025, is built on the Company's proprietary ULTC technology platform.

We believe that our purpose-built solution has the potential to drive additional market growth in ablative treatment of the large, underserved VT patient population.

We have established a robust cadence of clinical data designed to evaluate our technology and gain regulatory approvals of our product portfolio. Preliminary data suggest that our approach to treating VT offers a favorable combination of safety, acute and chronic effectiveness, compared to the current standard of care, including ablations performed using radiofrequency ("RF") and pulsed field ablation ("PFA") energy. Our first-in-human CRYOCURE-VT trial included 64 patients in nine centers in the European Union and Canada. The outcomes of this trial, which were used to support CE Mark approval, include a 0% rate of major adverse events, 94% acute procedural success, 60% freedom from sustained VT and 81% freedom from implantable cardioverter defibrillator ("ICD") shock at six months. Our vCLASTM. Cryoablation System for VT has obtained European CE Mark approval. In the United States, our 209-patient FULCRUM-VT IDE pivotal clinical trial completed enrollment in October 2025 across nineteen (19) centers in the United States and Canada. The study includes patients with both ischemic ("ICM") and non-ischemic ("NICM") cardiomyopathies (LVEF=35+/-10%, 33% NICM, 75% with congestive heart failure). In our preliminary acute safety and efficacy results, acute clinical success, defined as non-inducibility of target ventricular arrhythmias, was 97.4%, with all clinically-relevant VTs eliminated in 96.7% of patients tested by post-ablation programmed electrical stimulation. Key safety findings included a 2.5% rate of major adverse events including four (1.9%) peri-procedural deaths, of which one (0.5%) was adjudicated by an independent clinical events committee as definitely related to the investigational device. We plan to submit the results of this trial to support our application for U.S. Food and Drug Administration ("FDA") approval of our vCLASTM Cryoablation System in the first half of 2026, and to share our six-month primary efficacy endpoint results of the FULCRUM-VT trial in April 2026 at the Heart Rhythm 2026 Conference.

We are also currently developing a next generation ULTC technology for VT. This catheter, which requires only a single freeze, is being designed to improve customer usability and integration with the existing ablation laboratory workflow. The next-generation catheter features a more flexible, smaller diameter shaft that is compatible with the industry-standard 8.5 Fr sheaths, and is designed to operate at lower ablation temperatures resulting in the shorter, single-freeze ablation protocol. We are currently in the design phase with this device.

We have also developed a technology that utilizes ULTC in combination with PFA, which we call Pulsed Field Cryoablation ("PFCA"). Early demonstration of PFCA technology has been performed in the European PARALELL trial in patients with persistent atrial fibrillation and in preclinical studies targeting VT ablations.

We have incurred net losses each year since our inception in 2011. As of September 30, 2025, and December 31, 2024, we had an accumulated deficit of $92.3 million and $70.6 million, respectively. For the three and nine months ended September 30, 2025 (Successor), and for the periods from July 31, 2024 to September 30, 2024 (Successor), and January 1, 2024 to July 30, 2024 (Predecessor), net (loss) income was $(10.1) million, $(21.8) million, $3.6 million, and $(21.3) million, respectively. The net cash used in operating activities was $14.9 million, $6.4 million, and $16.0 million respectively. Substantially all of our accumulated deficit has resulted from costs incurred in connection with our research and development programs and from general and administrative costs associated with our operations. As of September 30, 2025, and December 31, 2024, we had cash of $4.7 million and $20.6 million, respectively.

Recent Developments

On October 14, 2025, we entered into a Securities Purchase Agreement (the "Securities Purchase Agreement") with certain accredited healthcare investors (the "Purchasers") pursuant to which we issued and sold to the Purchasers in a private placement (the "Private Placement"): (i) 9,792,506 shares (the "Shares") of our common stock, par value $0.0001 per share (the "Common Stock"), or pre-funded warrants (the "Pre-Funded Warrants") to purchase shares of Common Stock in lieu thereof, and (ii) accompanying (a) Tranche A Warrants to purchase an aggregate of 6,012,943 shares of Common Stock (or pre-funded warrants in lieu thereof) (the "Tranche A Warrants"), Tranche B Warrants to purchase an aggregate of 6,012,943 shares of Common Stock (or pre-funded warrants in lieu thereof) (the "Tranche B Warrants") and Tranche C Warrants to purchase an aggregate of 6,012,943 shares of Common Stock (or pre-funded warrants in lieu thereof) (the "Tranche C Warrants" and, together with the Tranche A and Tranche B Warrants, the "Milestone Warrants"), for aggregate gross proceeds of approximately $19 million (excluding up to approximately $31 million of aggregate gross proceeds that may be received in the future upon the cash exercise in full of the Milestone Warrants issued in the Private Placement), before deducting placement agent fees and other expenses payable by us. Each Share and each Pre-Funded Warrant sold pursuant to the Securities Purchase Agreement was accompanied by one Tranche A Warrant, one Tranche B Warrant and one Tranche C Warrant. The combined purchase price of each Share and accompanying Milestone Warrants is $1.9403 and (which includes $0.2303 for the Milestone Warrants sold with each Share in accordance with the rules and regulations of The Nasdaq Stock Market LLC). The combined purchase price of each Pre-Funded Warrant and accompanying Milestone Warrant is $1.9402 (equal to the combined purchase price per Share and accompanying Milestone Warrants, minus $0.001). Entities affiliated with Perceptive Advisors LLC, an affiliate of the Company, purchased Pre-Funded Warrants and Milestone Warrants for an aggregate purchase price of $4,250,000.

Each Milestone Warrant is exercisable for one share of Common Stock at an exercise price of $1.71 per share. The Milestone Warrants will expire upon the earlier of (i) five years from the date of issuance or (ii) (a) for the Tranche A Warrants, the date that is thirty (30) days following our announcement of results from our FULCRUM-VT IDE pivotal clinical trial, (b) for the Tranche B Warrants, the date that is thirty (30) days following our announcement of FDA approval of our vCLAS Cryoablation System, and (c) for the Tranche C Warrants, the date that is thirty (30) days following our announcement of FDA approval of our second generation vCLAS catheter system. The Pre-Funded Warrants are exercisable for one share of Common Stock at an exercise price of $0.0001 per share. The Pre-Funded Warrants are immediately exercisable and may be exercised at any time until all of the Pre-Funded Warrants are exercised in full.

A holder (together with its affiliates) of the Pre-Funded Warrants or Milestone Warrants, as the case may be, may not exercise any portion of the Pre-Funded Warrants or Milestone Warrants to the extent that the holder would own more than 4.99% (or, at the holder's option upon issuance, 9.99%) of our outstanding Common Stock immediately after exercise, which percentage may be changed at the holder's election to a lower or higher percentage not in excess of 19.99% upon 61 days' notice to us subject to the terms of the Pre-Funded Warrants or the Milestone Warrants. In lieu of making the cash payment otherwise contemplated to be made to us upon exercise of a Milestone Warrant, after the deadline for effectiveness of the registration statement to be filed pursuant to the Registration Rights Agreement, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of Common Stock determined according to a formula set forth in the Milestone Warrants, provided that such cashless exercise shall only be permitted if, at the time of such exercise, there is no effective registration statement registering the resale of shares of Common Stock underlying the Milestone Warrants or if the prospectus contained in such registration statement is not available for the resale of shares of Common Stock underlying the Milestone Warrants by the Milestone Warrant holder.

In lieu of making the cash payment otherwise contemplated to be made to us upon exercise of a Pre-Funded Warrant in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of Common Stock determined according to a formula set forth in the Pre-Funded Warrants.

Going Concern and Operating Outlook

The accompanying condensed consolidated financial statements have been prepared on a basis that assumes we will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. We have limited revenue and have experienced recurring operating losses and negative cash flows from operations since our inception and anticipate that we will continue to do so for at least the next several years.

In October 2025, we announced a private placement of our common stock (or pre-funded warrants to purchase common stock in lieu thereof) and accompanying warrants to purchase shares of common stock, for aggregate gross proceeds of approximately $19 million (excluding up to $31 million of additional potential gross proceeds from the cash exercise of the common stock warrants) (the "Private Placement").

As of the report date, we believe our existing cash and cash equivalents, including the proceeds received from the Private Placement, are sufficient to fund our operating and capital expenditure requirements for at least 12 months from the date of issuance of the unaudited interim condensed consolidated financial statements included in this Quarterly Report on Form 10-Q. If our available cash and cash equivalents are insufficient to satisfy our liquidity requirements, we may need to raise additional capital to fund our operations. No assurance can be given as to whether additional needed financing will be available on terms acceptable to us, if at all. If sufficient funds on acceptable terms are not available when needed, we may be required to suspend or forego certain planned activities. Failure to manage discretionary spending or raise additional financing, as needed, would adversely impact our ability to achieve our intended business objectives and have an adverse effect on our results of operations and future prospects. Refer to Note 1 - Organization and Description of Business in our condensed consolidated financial statements for additional information on the going concern assessment.

The need for additional capital in the future will depend in part on the scope and costs of our development and clinical activities. To date, we have not generated significant revenue from the sale of commercialized products. Once we conduct a full commercial launch, our ability to generate product revenue will depend on the successful commercialization of our products. Until such time, if ever, we expect to finance our operations through the sale of equity or debt, borrowings under credit facilities, or through potential collaborations, other strategic transactions, or government and other grants. Adequate capital may not be available to us when needed or on acceptable terms. If we are unable to raise capital, we could be forced to delay, reduce, suspend, or cease our research and development programs or any future commercialization efforts, which would have a negative impact on our business, prospects, operating results, and financial condition. See the section of this Report titled "Risk Factors" for additional information.

As a result of the Business Combination, we became subject to the reporting requirements under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and listing standards of the Nasdaq Capital Market, which will necessitate us to hire additional personnel and implement procedures and processes to address such public company requirements. We expect to incur additional ongoing expenses as a public company for, among other things, directors' and officers' liability insurance, director fees, and additional internal and external accounting, legal and administrative resources.

Our future results of consolidated operations and financial position may not be comparable to historical results as a result of the Business Combination.

Key Factors Affecting Our Performance

We compete primarily on the basis that our products are designed to enable more physicians to treat more patients more efficiently and effectively. Our continued success depends on our ability to:

continue to develop innovative, proprietary products that address significant clinical needs in a manner that is safe and effective for patients and easy-to-use for physicians;

•obtain and maintain regulatory clearances or approvals;

•demonstrate safety and effectiveness in our sponsored and third-party clinical trials;

•increase physician awareness of our products;

•obtain and maintain coverage and adequate reimbursement for procedures using our products;

•attract and retain skilled research, development, sales and clinical personnel;

•cost-effectively manufacture, market and sell our products; and

obtain, maintain, enforce and defend our intellectual property rights and operate our business without infringing, misappropriating or otherwise violating the intellectual property rights of others.

Innovation

Our business strategy relies significantly on innovation to develop and introduce new products and to differentiate our products from our competitors. We expect our research and development expenditures to increase as we make additional investments to support our growth strategies. We plan to increase our research and development expenditures with internal initiatives. We also expect expenditures associated with our manufacturing organization to grow over time as production volume increases and we bring new products to market. Our internal and external investments will be focused on initiatives that we believe will offer the greatest opportunity for growth and profitability.

Regulatory

Our commercial success will depend upon a number of factors, some of which are beyond our control, including the receipt of regulatory clearances, approvals, or authorizations for existing or new product offerings by us, or product enhancements. We must complete additional clinical testing before we can seek regulatory approval in the United States and begin commercialization of our products. After our products are cleared, approved, or authorized, numerous and pervasive regulatory requirements continue to apply. As such, our ability to navigate, obtain and maintain the required regulatory clearances, approvals, or authorizations, as well as comply with other regulatory requirements, for our products will in part drive our results of operations and impact our business.

Investments in Our Growth

In order to generate future growth, we plan to continue to expand and leverage our sales and marketing infrastructure to increase our customer base and grow our business. Identifying and recruiting qualified sales and marketing personnel and training them on our products, applicable federal and state laws and regulations, and on our internal policies and procedures requires significant time, expense and attention. It often takes several months or more before a sales representative is fully trained and productive. Our ability to increase our customer base and achieve broader market acceptance of our products will also depend to a significant extent on our ability to expand our marketing efforts as our plans to dedicate significant resources to our marketing programs.

Competition

Our industry is intensely competitive, subject to rapid change and significantly affected by new product introductions and other market activities of industry participants. Our most significant competitors are large, well-capitalized companies. We must continue to successfully compete considering our competitors' existing and future products and related pricing and their resources to successfully market to the physicians who could use our products. Publications of clinical results by us, our competitors and other third parties can also have a significant influence on whether, and the degree to which, we are able to gain market share and increase utilization of our products.

Reimbursement and Insurance Coverage

In both U.S. and non-U.S. markets, our ability to successfully commercialize and achieve market acceptance of our products depends, in significant part, on the availability of adequate financial coverage and reimbursement from third-party payors, including governmental payors (such as the Medicare and Medicaid programs in the United States), managed care organizations and private health insurers. Third-party payors decide which treatments they will cover and establish reimbursement rates for those treatments. Our products are purchased by hospitals and other providers who will then seek reimbursement from third-party payors for the procedures performed using our products. Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtained on a country-by-country basis. In certain international markets, a product must be approved for reimbursement before it can be approved for sale in that country. Furthermore, many international markets have government-managed healthcare systems that control reimbursement for new devices and procedures. In most markets there are private insurance systems as well as government-managed systems.

Key Components of Results of Operations

Revenue

We generate product revenue primarily from the sale of the catheters used with our consoles. We sell our products directly to hospitals and medical centers. To a lesser extent, we also generate lease revenue from the implied rental of consoles loaned to customers at no charge. We recognize revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers, when we transfer promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Please refer to Note 2 - Summary of Significant Accounting Policies in our condensed consolidated financial statements for additional details on our revenue recognition policy. Our revenue is subject to fluctuation due to the foreign currency in which our products are sold.

Cost of revenue and operating expenses

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 our products. Cost of revenue also includes the depreciation expense of consoles loaned to the customers.

Research and development expenses

Research and development expenses are expensed when incurred and are related to the development of our product candidates which includes pre-clinical, clinical, quality assurance, and research and development operational activities. These costs consist of:

salaries, benefits, and other employee-related costs, including stock-based compensation expense for personnel engaged in research and development functions;

•activities associated with clinical trials performed by third parties;

•professional fees;

•equipment, materials, and costs related to product manufacturing; and

•other operational costs including rent and facilities costs, and depreciation.

We do not track research and development expenses by project or product, as we are at an earlier stage in our pre-clinical and clinical development. Our management believes that the breakdown of research and development expenses by project or product would be arbitrary and would not provide a meaningful assessment.

Management expects the research and development expenses to increase in future periods, as we will incur incremental expenses associated with our ULTC products that are currently under development and in pre-clinical and clinical trials. Product candidates in later stages of clinical development generally have higher development costs, primarily due to the increased size and duration of later-stage clinical trials.

63

Table of Contents

Selling, general and administrative expenses

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 corporate matters, professional fees for accounting and consulting services, public company costs, insurance costs, and marketing costs. We expense all selling, general and administrative costs as incurred. We expect our selling, general and administrative expenses to decrease slightly for the full year 2025 compared to the full year 2024. This anticipated decrease is primarily due to lower payroll and personnel expenses resulting from the corporate prioritization initiative implemented on February 28, 2025, as well as the absence of transaction-related costs incurred in connection with the Business Combination completed in 2024. In future periods we expect our selling, general and administrative expenses to increase as we continue to expand on our operations and grow our business.

Convertible notes fair value adjustment

We recorded the 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", or the "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"), at fair value at issuance and subsequently remeasure them to fair value at each reporting period. The change in fair value of the Convertible Securities Notes, including amounts related to interest, is recorded in "Convertible notes fair value adjustment."

In connection with the execution of the Business Combination Agreement, the Convert Investors executed the Convertible Security Subscription Agreement, pursuant to which ListCo issued on the Closing Date to the Convert Investors the Convertible Securities Notes, which will be convertible into shares of the Company's Common Stock at a conversion price of $10.00 per share, subject to adjustment, and the Convert Warrants, each Convert Warrant being exercisable on a cashless basis or for cash at a price of $24.00 per share, subject to adjustment. Such $20.0 million of financing in the form of Convertible Securities Notes includes the conversion of the 2024 Bridge Financing Notes into Convertible Securities Notes and Convert Warrants at Closing.

Warrant liabilities fair value adjustment

We accounted for certain common stock warrants outstanding as warrant liabilities at fair value, determined using the Black-Scholes-Merton option pricing model. The liability is subject to remeasurement at each reporting period and any change in fair value is recognized as warrant liabilities fair value adjustment in the condensed consolidated statements of operations and comprehensive loss (income).

Interest expense

Interest expense is primarily incurred from our outstanding debt obligations, including those under the October 2022 Convertible Notes, the Bridge Financing Notes, the Convertible Securities Notes and the SVB Term Loan (as defined below).

Interest income

Interest income consists primarily of interest earned on our cash, cash equivalents, and money market accounts.

Other (expense) income, net

Other (expense) income, net primarily consists of foreign currency unrealized and realized gain / loss, and other income related to our research and development ("R&D") tax credit.

Revenue

Revenue was nil for the three months ended September 30, 2025 (Successor), compared to $0.1 million and $53.0 thousand for the periods from July 31, 2024 to September 30, 2024 (Successor) and from July 1, 2024 to July 30, 2024 (Predecessor), respectively, representing a decrease of $0.2 million. The decrease was primarily due to the repurchase of previously sold inventory during the three months ended September 30, 2025 (Successor), which offset gross sales. This inventory buyback was undertaken in connection with our pause in commercial activity in Europe.

Revenue was nil for the nine months ended September 30, 2025 (Successor), compared to $0.1 million and $0.3 million for the periods from July 31, 2024 to September 30, 2024 (Successor) and from January 1, 2024 to July 30, 2024 (Predecessor), respectively, representing a decrease of $0.5 million. The decrease was primarily due to the repurchase of previously sold inventory during the nine months ended September 30, 2025 (Successor), which offset gross sales. This inventory buyback was undertaken in connection with our pause in commercial activity in Europe.

Cost of revenue and operating expenses

Cost of revenue

Cost of revenue was $31.0 thousand for the three months ended September 30, 2025 (Successor), compared to $0.4 million and $0.2 million for the period from July 31, 2024 to September 30, 2024 (Successor) and from July 1, 2024 to July 30, 2024 (Predecessor), respectively, representing a decrease of $0.5 million, or 94.6%. The decrease was primarily attributable to a pause in commercial activity in Europe during 2025 and the related impact of an inventory buyback conducted in connection with the pause.

Cost of revenue was $0.6 million for the nine months ended September 30, 2025 (Successor), compared to $0.4 million and $1.4 million for the period from July 31, 2024 to September 30, 2024 (Successor) and from January 1, 2024 to July 30, 2024 (Predecessor), respectively, representing a decrease of $1.2 million, or 65.1%. The decrease was primarily attributable to a pause in commercial activity in Europe during 2025 and the related impact of an inventory buyback conducted in connection with the pause.

Research and development expenses

Research and development expenses were $2.8 million for the three months ended September 30, 2025 (Successor), compared to $1.2 million and $1.3 million for the period from July 31, 2024 to September 30, 2024 (Successor) and from July 1, 2024 to July 30, 2024 (Predecessor), respectively, representing an increase of $0.3 million, or 12.4%. The increase was primarily driven by a $0.5 million increase in clinical trial costs, partially offset by a $0.2 million decrease in quality assurance costs.

Research and development expenses were $8.4 million for the nine months ended September 30, 2025 (Successor), compared to $1.2 million and $7.6 million for the period from July 31, 2024 to September 30, 2024 (Successor) and from January 1, 2024 to July 30, 2024 (Predecessor), respectively, representing a decrease of $0.4 million, or 4.5%. This decrease was primarily driven by a $1.4 million decrease in quality assurance, operations, and other research and development costs, partially offset by a $1.0 million increase in clinical trials costs.

Selling, general and administrative expenses

Selling, general and administrative expenses were $2.9 million for the three months ended September 30, 2025 (Successor) and $2.9 million and $4.9 million for the period from July 31, 2024 to September 30, 2024 (Successor) and from July 1, 2024 to July 30, 2024 (Predecessor), respectively. The decrease in selling, general and administrative expenses of $4.9 million, or 62.5%, was primarily due to a decrease in payroll and personnel expense related to lower headcount during the three months ended September 30, 2025, as compared to the prior periods.

Selling, general and administrative expenses were $8.9 million for the nine months ended September 30, 2025 (Successor) and $2.9 million and $13.0 million for the period from July 31, 2024 to September 30, 2024 (Successor) and from January 1, 2024 to July 30, 2024 (Predecessor), respectively. The decrease in selling, general and administrative expenses of $7.1 million, or 44.3%, was primarily due to a decrease in payroll and personnel expense related to lower headcount during the nine months ended September 30, 2025, as compared to the prior year periods. Additionally, we changed our estimate of the useful life of our consoles from five years to three years and recognized a catch-up in January 2024, which increased depreciation expense in 2024.

Convertible notes fair value adjustment

The change in convertible notes fair value resulted in a loss of $3.5 million and $1.9 million for the three and nine months ended September 30, 2025 (Successor) respectively. The change in convertible notes fair value resulted in a gain of $3.3 million and a loss of $1.9 million for the period from July 31, 2024 to September 30, 2024 (Successor) and from July 1, 2024 to July 30, 2024 (Predecessor), respectively. The change in convertible notes fair value resulted in a gain of $3.3 million and $2.1 million for the period from July 31, 2024 to September 30, 2024 (Successor) and from January 1, 2024 to July 30, 2024 (Predecessor), respectively.

The increase of $10 thousand, or 1.4%, was related to interest incurred from the convertible promissory notes issued in April 2023, November 2023, February 2024, May 2024, June 2024, July 2024 Notes, and the Convertible Securities Notes.

Interest expense was $2.1 million for the nine months ended September 30, 2025 (Successor) and $0.4 million and $1.8 million for the period from July 31, 2024 to September 30, 2024 (Successor) and from January 1, 2024 to July 30, 2024 (Predecessor), respectively.

The decrease in interest income of $87.0 thousand was primarily due to the decrease of cash balances in an asset management account.

Interest income was $0.3 million for the nine months ended September 30, 2025 (Successor) and $0.2 million and $3.0 thousand for the period from July 31, 2024 to September 30, 2024 (Successor) and from January 1, 2024 to July 30, 2024 (Predecessor), respectively. The increase in interest income of $0.2 million was primarily due to the increase of cash balances in an asset management account.

Other income, net was $12.0 thousand for the three months ended September 30, 2025 (Successor) and other income was $72.0 thousand and $5.0 thousand for the period from July 31, 2024 to September 30, 2024 (Successor) and from July 1, 2024 to July 30, 2024 (Predecessor), respectively. This net decrease in other income of $0.1 million was primarily attributable to foreign currency unrealized and realized loss.

Other income, net was $0.2 million for the nine months ended September 30, 2025 (Successor) and other income was $72.0 thousand and other expense was $33.0 thousand for the period from July 31, 2024 to September 30, 2024 (Successor) and from January 1, 2024 to July 30, 2024 (Predecessor), respectively.

Liquidity and Capital Resources

Sources of Liquidity

To date, we have financed our operations primarily through the sale of equity securities, convertible promissory notes and the SVB Term Loan (as defined below). In connection with the closing of the Business Combination on July 31, 2024, we received net proceeds of $84.2 million. Since inception we have incurred operating losses and negative cash flows and anticipate continuing to do so for at least the next several years.

As of September 30, 2025, and December 31, 2024, the Company had cash and cash equivalents of $4.7 million and $20.6 million, respectively. For the nine months ended September 30, 2025 (Successor), net losses were ($21.8) million. For the period from July 31, 2024 to September 30, 2024 (Successor) and from January 1, 2024 to July 30, 2024 (Predecessor), net income (losses) were $3.6 million and $(21.3) million, respectively. For the nine months ended September 30, 2025 (Successor) and the period from July 31, 2024 to September 30, 2024 (Successor) and the period from January 1, 2024 to July 30, 2024 (Predecessor), net cash used in operating activities was $14.9 million, $6.4 million, and $16.0 million, respectively.

On October 20, 2025, we announced the closing of the Private Placement which resulted in up front, aggregate gross proceeds of approximately $19 million. After deducting estimated offering expenses, the net proceeds from the Private Placement are expected to provide us with additional liquidity to fund planned operations and working capital needs. For more information see "-Recent Developments" above.

Future Funding Requirements

In the future, we may need to raise additional funds through the issuance of debt and/or equity securities or otherwise. Until such time, if ever, that we can generate revenue sufficient to achieve profitability, we expect to finance our operations through equity or debt financings, which may not be available to us on the timing needed or on terms that we deem to be favorable. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of common stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making acquisitions or capital expenditures or declaring dividends. If we are unable to maintain sufficient financial resources, our business, financial condition and results of operations will be materially and adversely affected. We may be required to delay, limit, reduce or terminate our product discovery and development activities or future commercialization efforts.

We believe that our existing cash and cash equivalents, including the anticipated net proceeds from the Private Placement, will enable us to fund our ongoing development and submission activities to support FDA evaluation of our first and next generation ULTC products. We will require additional capital to fund continued clinical activities for our next generation product, to fund our manufacturing activities, to fund precommercial activities of our programs and for working capital and general corporate purposes. The assessment of our ability to meet our future obligations is inherently judgmental, subjective and susceptible to change. Based on our current forecast, we believe that we will have sufficient cash to maintain our planned operations for the next twelve months following the issuance of these condensed consolidated financial statements.

Table of Contents

Because of the numerous risks and uncertainties associated with research, development and commercialization of medical products, we are unable to estimate the exact amount of our operating capital requirements. Our future funding requirements will depend on many factors, including, but not limited to:

•our revenue growth;

•our research and development efforts;

•our sales and marketing activities;

•our ability to raise additional funds to finance our operations;

•the outcome, costs and timing of any clinical trial results for our current or future products;

•the emergence and effect of competing or complementary products;

•the availability and amount of reimbursement for procedures using our products;

our ability to maintain, expand and defend the scope of our intellectual property portfolio, including the amount and timing of any payments we may be required to make, or that we may receive, in connection with the licensing, filing, prosecution, defense and enforcement of any patents or other intellectual property rights;

our ability to retain our current employees and the need and ability to hire additional management and sales, scientific and medical personnel;

•the terms and timing of any collaborative, licensing or other arrangements that we have or may establish;

•debt service requirements; and

•the extent to which we acquire or invest in businesses, products or technologies.

Our primary uses of capital are, and we expect will continue to be, investment in clinical research and development, and related supplies, marketing and physician education, legal and other regulatory expenses, commercial activities, general administrative costs and working capital.

See the section of this Report titled "Risk Factors" for additional risks associated with our substantial capital requirements.

Comparison of the Nine Months Ended September 30, 2025 (Successor) to the Periods from January 1, 2024 to July 30, 2024 (Predecessor) and from July 31, 2024 to September 30, 2024 (Successor)

Cash Flows Used in Operating Activities

Net cash used in operating activities for the nine months ended September 30, 2025 (Successor) was $14.9 million, consisting primarily of a net loss of $21.8 million, adjusted by non-cash items of $4.0 million and net changes in operating assets and liabilities of $2.9 million. Non-cash items primarily consisted of $0.7 million in depreciation, $0.6 million in stock-based compensation, a loss on disposal of property and equipment of $0.5 million, a change in fair value of convertible notes payable of $1.9 million, and a change in fair value of warrant liabilities of $0.3 million. Changes in operating assets and liabilities were primarily driven by a $4.8 million increase in accrued liabilities, a $2.1 million increase in other accrued liabilities, a $1.1 million decrease in inventory, and a $0.3 million decrease in prepaid expenses and other current assets, partially offset by a $3.6 million decrease in other long-term liabilities and a $1.8 million decrease in accounts payable.

Net cash used in operating activities for the period from July 31, 2024 to September 30, 2024 (Successor) was $6.4 million, consisting primarily of net income of $3.6 million, adjusted by non-cash items of $7.9 million, and net changes in our operating assets and liabilities of $2.1 million. Non-cash items primarily consisted of $0.3 million in depreciation and amortization; offset by a gain of $3.3 million from the change in fair value of convertible notes payable and a gain of $5.0 million from the change in fair value of warrant liabilities. Changes in our net operating assets and liabilities were primarily due to a $0.3 million increase in other accrued liabilities which was primarily driven by interest payable on the convertible note; offset by $1.3 million increase in prepaid expenses and other current assets, $0.4 million decrease in accounts payable, and a $0.7 million decrease in accrued liabilities.

Net cash used in operating activities for the period from January 1, 2024 to July 30, 2024 (Predecessor) was $16.0 million consisting primarily of a net loss of $21.3 million, adjusted by non-cash items of $0.8 million, and net changes in our operating assets and liabilities of $6.1 million. Non-cash items primarily consisted of $0.6 million in depreciation and amortization, $0.6 million in stock-based compensation, noncash operating lease expense of $0.1 million, and loss on disposal of property and equipment of $0.1 million; offset by a gain of $2.1 million from the change in fair value of convertible notes payable, and a gain of $0.2 million from the change in fair value of warrant liabilities. Changes in our net operating assets and liabilities were primarily due to a $7.4 million increase in accrued transaction costs, the increase in accrued liabilities of $0.5 million and a $1.7 million increase in other accrued liabilities, which were primarily driven by the increase in transaction costs related to the Business Combination, the increase in accrued variable compensation related to the Business Combination, and the increase in interest related the convertible notes; offset by a $2.6 million decrease in accounts payable, $0.8 million increase in inventory, which were primarily driven by the payment of accounts payable related to the Business combination and an increase in inventory purchases.

Cash Flow Used in Investing Activities

Net cash used in investing activities for the nine months ended September 30, 2025 (Successor) was $0.9 million. Net cash used in investing activities for the periods from July 31, 2024 to September 30, 2024 (Successor) and January 1, 2024 to July 30, 2024 (Predecessor) was $0.6 million and $0.4 million, respectively. The increase was primarily due to higher purchases of property and equipment during the period.

Cash Flow Provided by Financing Activities

Net cash provided by financing activities for the nine months ended September 30, 2025 (Successor) was nil.

Net cash provided by financing activities for the period from January 1, 2024 to July 30, 2024 (Predecessor) was $15.6 million, primarily due to proceeds of $16.5 million from the issuance of the $7.0 million 2024 Bridge Financing Note, the $3.0 million May 2024 Convertible Notes, the $2.5 million June 2024 Convertible Notes, the $1.0 million July 2024 Convertible Notes, and the $3.0 million draw under the November 2023 Convertible Notes, partially offset by a $0.9 million repayment of the SVB Term Loan.

Off-Balance Sheet Arrangements

During the periods presented, we did not have, nor do we currently have, any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. We are, therefore, not exposed to the financing, liquidity, market, or credit risk that could arise if we had engaged in those types of relationships.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes included elsewhere in this Report. We base our estimates on historical experience, current business factors and various other assumptions that we believe are necessary to consider forming a basis for making judgments about the carrying values of assets and liabilities, the recorded amounts of revenue and expenses and the disclosure of contingent assets and liabilities. We are subject to uncertainties such as the impact of future events, economic and political factors, and changes in our business environment; therefore, actual results could differ from these estimates.

Accordingly, the accounting estimates used in the preparation of our condensed consolidated financial statements will change as new events occur, as more experience is acquired, as additional information is obtained and as our operating environment changes. Changes in estimates are made when circumstances warrant. Such changes in estimates and refinements in estimation methodologies are reflected in reported results of operations; if material, the effects of changes in estimates are disclosed in the notes to our condensed consolidated financial statements.

On an ongoing basis, we evaluate our estimates and assumptions. Our actual results may differ from these estimates under different assumptions or conditions.

During the three months ended September 30, 2025, there have been no material changes to our critical accounting policies from those disclosed in Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" of the 2024 Annual Report, except as noted below.

Emerging Growth Company and Smaller Reporting Company Status

We are an emerging growth company ("EGC"), as defined in the 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. We have elected to use this extended transition period to enable us to comply with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our 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, as an emerging growth company, we may take advantage of specified reduced disclosure and other requirements that are otherwise applicable generally to public companies. These provisions include:

an exception from compliance with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as amended;
reduced disclosure about our executive compensation arrangements in our periodic reports, proxy statements and registration statements;
exemptions from the requirements of holding non-binding advisory votes on executive compensation or golden parachute arrangements; and
an exemption from compliance with the requirements of the Public Company Accounting Oversight Board regarding the communication of critical audit matters in the auditor's report on financial statements.

We will remain an EGC under the JOBS Act until the earliest of (i) December 31, 2026 (ii) the last date of our fiscal year in which we have total annual gross revenue of at least $1.235 billion, (iii) the date on which we are deemed to be a "large accelerated filer" under the rules of the SEC with at least $700.0 million of outstanding securities held by non-affiliates, or (iv) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the previous three-years.

We are also a "smaller reporting company," meaning that the market value of our shares held by non-affiliates is less than $700 million and our annual revenue was less than $100 million during the most recently completed fiscal year. We may continue to be a smaller reporting company if either (i) the market value of our shares held by non-affiliates is less than $250 million or (ii) our annual revenue was less than $100 million during the most recently completed fiscal year and the market value of our shares held by non-affiliates is less than $700 million. If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies. Specifically, as a smaller reporting company, we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Report on Form 10-K and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.

Recent Accounting Pronouncements

Refer to Note 2 - Summary of Significant Accounting Policies in our condensed consolidated financial statements included elsewhere in this Report for a description of recent accounting pronouncements applicable to our financial statements.

Item 3.Quantitative and Qualitative Disclosures About Market Risk.

We are a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information required under this Item.

Item 4.Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain "disclosure controls and procedures," as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 1934 (the "Exchange Act") that are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. In designing and evaluating our disclosure controls and procedures, management recognized that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Our disclosure controls and procedures have been designed to meet reasonable assurance standards. Additionally, in designing disclosure controls and procedures, our management applies its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any disclosure controls and procedures also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Based on their evaluation as of the end of the period covered by this Quarterly Report on Form 10-Q, our Chief Executive Officer and Chief Financial Officer have concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting identified in management's evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the period covered by this Report that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1.Legal Proceedings.

From time to time, we may become involved in various claims and legal proceedings. Regardless of outcome, litigation and other legal and administrative proceedings can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. We are currently not a party to any legal proceedings, the outcome of which, if determined adversely to us, would individually or in the aggregate have a material adverse effect on our business, financial condition, and results of operations.

Item 1A. Risk Factors.

Except as set forth below, there have been no material changes from the risk factors disclosed in Part I, Item 1A. "Risk Factors" of our Annual Report on Form 10-K filed with the SEC on March 27, 2025 (the "2024 Annual Report"). The risk factors described in our 2024 Annual Report, as well as other information set forth in this Quarterly Report on Form 10-Q, could materially adversely affect our business, financial condition, results of operations and prospects, and should be carefully considered. The risks and uncertainties that we face, however, are not limited to those described in the 2024 Annual Report. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may also adversely affect our business and the trading price of our securities.

Risks Related to Our Business

International trade policies, including tariffs, sanctions and trade barriers may adversely affect our business, financial condition, results of operations and prospects.

We operate in a global economy, and our business depends on a global supply chain for the development, manufacturing, and distribution of our products, and for the advancement of our preclinical and clinical development programs. There is inherent risk, based on the complex relationships among the United States and the countries in which we conduct our business, that political, diplomatic, and national security factors can lead to global trade restrictions and changes in trade policies and export regulations that may adversely affect our business and operations. The current international trade and regulatory environment is subject to significant ongoing uncertainty.

We source some materials from international suppliers, with reliance on foreign manufacturers, including China. Tariff policies, particularly those affecting China could materially increase our costs and reduce our profitability, including as a result of our inability to adjust pricing in formulary-based markets. Recent and potential future changes in international trade policies, particularly regarding U.S. China trade relations present risks to our operations and financial performance.

Unlike many industries, our ability to pass increased costs to customers may be limited by the structure of medical device pricing and reimbursement systems. In many cases, pricing of medical devices are established through annual or multi-year contracts with commercial, third-party payors, customers, and group purchasing organizations, and reimbursement methodologies established by government programs, such as Medicare. These arrangements typically include fixed pricing terms. As a result, and depending on the timing and scope of our future commercialization and the implementation of any future tariffs, cost increases due to tariffs may be difficult or impossible to pass through to customers until the next negotiation cycle.

Current or future tariffs will also result in increased research and development expenses, including with respect to increased costs associated with raw materials, equipment and research materials and components. Trade restrictions affecting the import of materials necessary for clinical trials could result in delays to our development timelines. Increased development costs and extended development timelines could place us at a competitive disadvantage compared to companies operating in regions with more favorable trade relationships and could reduce investor confidence and negatively impact our business, results of operations, financial condition and growth prospects.

Table of Contents

The complexity of announced or future tariffs may also increase the risk that we or our customers or suppliers may be subject to civil or criminal enforcement actions in the United States or foreign jurisdictions related to compliance with trade regulations. Foreign governments may also adopt non-tariff measures, such as procurement preferences or informal disincentives to engage with, purchase from or invest in U.S. entities, which may limit our ability to compete internationally and attract non-U.S. investment, employees, customers and suppliers. Foreign governments may also take other retaliatory actions against U.S. entities, such as decreased intellectual property protection, increased enforcement actions, or delays in regulatory approvals, which may result in heightened international legal and operational risks. In addition, the United States and other governments have imposed and may continue to impose additional sanctions, such as trade restrictions or trade barriers, which could restrict us from doing business directly or indirectly in or with certain countries or parties and may impose additional costs and complexity to our business.

Trade disputes, tariffs, restrictions and other political tensions between the United States and other countries may also exacerbate unfavorable macroeconomic conditions including inflationary pressures, foreign exchange volatility, financial market instability, and economic recessions or downturns. The ultimate impact of current or future tariffs and trade restrictions remains uncertain and could materially and adversely affect our business, financial condition, and prospects. While we actively monitor these risks, any prolonged economic downturn, escalation in trade tensions, or deterioration in international perception of U.S.-based companies could materially and adversely affect our business, ability to access the capital markets or other financing sources, results of operations, financial condition and prospects. In addition, tariffs and other trade developments have and may continue to heighten the risks related to the other risk factors described in our 2024 Annual Report.

Our corporate prioritization initiative may not achieve our intended outcome and may result in significant adverse consequences.

In February 2025, we implemented a corporate prioritization initiative focusing all resources on the FULCRUM-VT clinical trial activities and our new product design optimization program. This corporate prioritization initiative may result in unintended consequences and costs, such as the loss of institutional knowledge and expertise, attrition beyond the intended number of employees, decreased morale among our remaining employees, and the risk that we may not achieve the anticipated benefits of the corporate prioritization initiative. If we are unable to realize the anticipated benefits from the corporate prioritization initiative, or if we experience significant adverse consequences from the corporate prioritization initiative, our business, financial condition, and results of operations may be materially adversely affected.

Risks Related to our Products

Changes in the regulatory landscape, policies, or processes, as well as disruptions at the FDA and other government agencies caused by layoffs, changes in personnel, funding shortages or global health concerns could negatively impact our business.

The ability of the FDA to review proposed clinical trials or approve new products can be affected by a variety of factors, including government budget and funding levels, statutory, regulatory, and policy changes, the FDA's ability to hire and retain key personnel and accept payment of user fees, and other events that may otherwise affect the FDA's ability to perform routine functions. In addition, government funding of other government agencies that fund research and development activities is subject to the political process, including executive and congressional priorities, the impacts of which are inherently fluid and unpredictable. Disruptions at the FDA and other agencies may slow the time necessary for new product candidates to be reviewed and/or approved, which would adversely affect our business. For example, over the last several years, including in October 2025, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical FDA employees and stop critical activities. If the current government shutdown continues or a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business.

The ability of the FDA and other government agencies to properly administer their functions is highly dependent on the levels of government funding and the ability to fill key leadership appointments, among various factors. Delays in filling or replacing key positions could significantly impact the ability of the FDA and other agencies to fulfill their functions and could greatly impact healthcare and the pharmaceutical industry. In addition, the current administration has implemented substantial reductions in force at various government agencies including the FDA, which could significantly reduce the FDA's capacity to perform its functions in a manner consistent with its past practices and could delay reviews and negatively impact our business. There is increased uncertainty as to how the FDA and other regulatory agencies will regulate our products.

A breakthrough device designation by the FDA for vCLASTM may not lead to a faster development, regulatory review or approval process, and it may not increase the likelihood that vCLASTM will receive premarket approval ("PMA") approval from the FDA.

In April 2025, we announced that the FDA granted breakthrough device designation for the vCLASTM Cryoablation System for the treatment of drug-refractory, recurrent, sustained monomorphic ventricular tachycardia in patients with ischemic or non-ischemic structural heart disease. Breakthrough Device designation provides potential benefits to device developers, including more interactive and timely communications with FDA staff, use of post-market data collection when scientifically appropriate, and opportunities for flexible clinical study design. The receipt of breakthrough device designation for vCLASTM may not result in a faster development process, review or approval compared to conventional FDA procedures and does not ensure ultimate PMA approval by the FDA. In addition, even if a product qualifies as a breakthrough device, the FDA may later decide that the product no longer meets the conditions for qualification.

Risks Related to Regulatory and Legal Compliance Matters

Our business could be negatively impacted by changes in the United States political environment.

Any changes in the political and regulatory landscape, policies, or processes, could significantly affect our business. Specific legislative and regulatory proposals discussed during election campaigns and more recently that might materially impact our business include, but are not limited to, promoting access to healthcare via market competition and pricing transparency, enhancing flexibility and choice in healthcare at the state and individual level, prioritizing domestic production and increasing tariffs on imports (which may complicate and increase costs associated with our supply chain), and rolling back regulatory initiatives adopted under the previous administration. We cannot predict whether industry initiatives to seek tariff carve-outs for devices or other life sciences goods and products will be successful. In addition, the current administration has implemented substantial reductions in force at various government agencies including the FDA, which could significantly reduce the FDA's capacity to perform its functions in a manner consistent with its past practices and could delay reviews and negatively impact our business. There is increased uncertainty as to how the FDA and other regulatory agencies will regulate our products. For example, the Bureau of Industry and Security, U.S. Department of Commerce, has initiated an investigation to determine whether medical devices, including their components and accessories, manufactured outside the United States pose a national security risk and should be subject to additional tariffs. In addition, the current administration also has issued, and is expected to continue relying upon, Executive Orders to address a wide range of policy areas, some of which may impact our business. Such political developments may require us to allocate significant time, resources, and expense to modifying our policies and procedures, processes, systems, and practices to ensure compliance or adapt to the new regulatory climate, particularly to the extent such actions are subject to protracted and uncertain legal challenges. To the extent changes in the political environment have a negative impact on us or on our markets, our business, results of operation, and financial condition could be materially and adversely affected in the future.
