Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation The condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the periods presented. Certain information and note disclosures normally included in the Company’s annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These condensed consolidated financial statement results are not necessarily indicative of results to be expected for the full fiscal year or any future period. Principles of Consolidation The condensed consolidated financial statements include the accounts of Acutus Medical, 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 identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker in making decisions regarding resource allocation and assessing performance. The Company views its operations and manages its business as one operating segment and reportable segment. Cash and Cash Equivalents and Restricted Cash The Company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents. All of the Company’s cash equivalents have liquid markets and high credit ratings. The Company maintains its cash in bank deposits and other accounts, the balances of which, at times and as of September 30, 2023 and December 31, 2022, exceeded federally insured limits. Restricted cash consists of (i) deposited cash collateral for the Company’s corporate credit card program and (ii) cash received for the sale of business to Medtronic held in an indemnity escrow account until certain terms of sale are met. The following table reconciles cash, cash equivalents and restricted cash in the condensed consolidated balance sheets to the total balances as of September 30, 2023 and December 31, 2022 (in thousands): September 30, December 31, (unaudited) Cash and cash equivalents $ 24,100 $ 25,584 Restricted cash 7,015 5,764 Total cash, cash equivalents and restricted cash $ 31,115 $ 31,348 Marketable Securities The Company’s marketable securities portfolio consists of investments in money market funds, commercial paper, U.S. treasury securities, Yankee debt securities, and asset-backed securities. The Company considers its debt securities to be available-for-sale securities. Available-for-sale securities are classified as cash equivalents or short-term or long-term marketable securities based on the maturity date at time of purchase and their availability to meet current operating requirements. Marketable securities that mature in three months or less from the date of purchase are classified as cash equivalents. Marketable securities, excluding cash equivalents, that mature in one year or less are classified as short-term available-for-sale securities and are reported as a component of current assets. Securities that are classified as available-for-sale are measured at fair value with temporary unrealized gains and losses reported in other comprehensive income (loss), and as a component of stockholders’ equity until their disposition or maturity. See Fair Value Measurements, below. The Company reviews all available-for-sale securities at each period end to determine if they remain available-for-sale based on the Company’s current intent and ability to sell the security if it is required to do so. Realized gains and losses from the sale of marketable securities, if any, are calculated using the specific-identification method. Marketable securities are subject to a periodic impairment review. The Company may recognize an impairment charge when a decline in the fair value of investments below the cost basis is determined to be other-than-temporary. In determining whether a decline in market value is other-than-temporary, various factors are considered, including the cause, duration of time and severity of the impairment, any adverse changes in the investee’s financial condition and the Company’s intent and ability to hold the security for a period of time sufficient to allow for an anticipated recovery in market value. Declines in value judged to be other-than-temporary are included in the Company’s condensed consolidated statements of operations and comprehensive loss. The Company did not record any other-than-temporary impairments related to marketable securities in the Company’s condensed consolidated statements of operations and comprehensive loss for the three and nine months ended September 30, 2023 and 2022. Concentrations of Credit Risk and Off-Balance Sheet Risk Financial instruments that potentially subject the Company to credit risk consist principally of cash, cash equivalents, restricted cash, accounts receivable and marketable securities. The Company has not experienced losses on these accounts, and management believes, based upon the quality of the financial institutions, that the credit risk with regard to these deposits is not significant. Revenue from Contracts with Customers The Company accounts for revenue earned from contracts with customers under Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers (“ASC 606”), and ASC 842, Leases ("ASC 842"). 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 following five steps are applied to achieve that core principle: • 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. ASC 842 provides guidance on determining whether an agreement contains a lease. ASC 842 defines a lease as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. For new customers, the Company places its medical diagnostic equipment, the AcQMap System, at customer sites under evaluation agreements and generates revenue from the sale of disposable products used with the AcQMap System. Disposable products primarily include AcQMap Catheters and AcQGuide Steerable Sheaths. Outside of the United States, the Company also has the Qubic Force Device which generates revenue from the sale of the AcQBlate Force Ablation Catheters. The Company provides the disposable products in exchange for consideration, which occurs when a customer submits a purchase order and the Company provides disposables at the agreed upon prices in the invoice. Generally, customers purchase disposable products using separate purchase orders after the equipment has been provided to the customer for free with no binding agreement or requirement to purchase any disposable products. The Company has elected the practical expedient and accounting policy election to account for the shipping and handling as activities to fulfill the promise to transfer the disposable products and not as a separate performance obligation. Additionally, the Company sells the AcQMap System to customers along with software updates on a when-and-if-available basis, as well as the Qubic Force Device and a transseptal crossing line of products which can be used in a variety of heart procedures and does not need to be accompanied with an AcQMap System or Qubic Force Device. Included in the transseptal crossing line of products are primarily the AcQRef Introducer Sheath, the AcQGuide Sheaths and the AcQCross Transseptal Dilator/Needle. The Company also enters into deferred equipment agreements that are generally structured such that the Company agrees to provide an AcQMap System at no up-front charge, with title of the device transferring to the customer at the end of the contract term, in exchange for the customer’s commitment to purchase disposables at a specified price over the term of the agreement, which generally ranges from two Lastly, the Company enters into short-term operating leases for the rental of the AcQMap System after an evaluation. These lease agreements impose no requirement on the customer to purchase the equipment, and the equipment is not transferred to the customer at the end of the lease term. The short-term nature of the lease agreements does not result in lease payments accumulating to an amount that equals the value of the equipment nor is the lease term reflective of the economic life of the equipment. The Company’s contracts primarily include fixed consideration. Generally, there are no discounts, rebates, returns or other forms of variable consideration. Customers are generally required to pay within 30 to 60 days. The delivery of disposable products are performance obligations satisfied at a point in time. The disposable products are shipped Free on Board (“FOB”) shipping point or FOB destination. For disposable products that are shipped FOB shipping point, the customer has the significant risks and rewards of ownership and legal title to the assets when the disposable products leave the Company’s shipping facilities, at which point the customer obtains control and thus revenue is recognized at that point in time. Revenue is recognized on delivery for disposable products shipped FOB destination. For direct customers, the installation and delivery of the AcQMap System is satisfied at a point in time when the installation is complete, which is when the customer can benefit and has control of the system. For AcQMap System sold to Biotronik SE & Co. KG (“Biotronik”), the installation is not a performance obligation as it is performed by Biotronik, and therefore the AcQMap System is satisfied at a point in time when they have control of the system. The Company’s software updates and equipment service performance obligations are satisfied evenly over time as the customer simultaneously receives and consumes the benefits of the Company’s performance for these services throughout the service period. The Company allocates the transaction price to each performance obligation identified in the contract based on the relative standalone selling price (“SSP”). The Company determines SSP for the purposes of allocating the transaction price to each performance obligation based on the adjusted market assessment approach that maximizes the use of observable inputs, which include, but are not limited to, sales transactions where the specific performance obligations are sold separately, Company list prices and specific offers to customers. Except for the deferred equipment agreements noted above, the Company’s contracts with customers generally have an expected duration of one year or less, and therefore the Company has elected the practical expedient in ASC 606 to not disclose information about its remaining performance obligations. Any incremental costs to obtain contracts are recorded as selling, general and administrative ("SG&A") expense as incurred due to the short duration of the Company’s contracts. The Company’s contract balances consisted solely of accounts receivable as of September 30, 2023 and December 31, 2022. In May 2020, the Company entered into bi-lateral distribution agreements (the “Bi-Lateral Distribution Agreements”) with Biotronik. Pursuant to the Bi-Lateral Distribution Agreements, the Company obtained a non-exclusive license to distribute a range of Biotronik’s products and accessories in the United States, Canada, China, Hong Kong and multiple Western European countries under the Company’s private label. Moreover, if an investigational device exemption (“IDE”) clinical trial is required for these products to obtain regulatory approval in the United States, or a clinical trial is required for these products to obtain regulatory approval in China, the Company will obtain an exclusive distribution right in such territories for a term of up to five years commencing on the date of regulatory approval if the Company covers the cost of the IDE or other clinical trial and the Company conducts such study within a specified period. Biotronik also agreed to distribute the Company’s products and accessories in Germany, Japan, Mexico, Switzerland and multiple countries in Asia-Pacific, Eastern Europe, the Middle East and South America. The Company also granted Biotronik a co-exclusive right to distribute these products in Hong Kong. Each party will pay to the other party a specified transfer price on the sale of the other party’s products and, accordingly, will earn a distribution margin on the sale of the other party’s products. The foregoing description applies to products that will no longer be manufactured and sold by the Company upon completion of the Restructuring. See Note 1 – Organization and Description of Business – Liquidity, Capital Resources and Going Concern , above. In 2022, the Company sold its left-heart access transseptal crossing business to Medtronic. In connection with the sale, the Company entered into a distribution agreement (the "Distribution Agreement") with Medtronic, pursuant to which the Company acts as the original equipment manufacturer ("OEM") supplier of these products. The Company will produce and sell the products to Medtronic for a period of up to four years. Revenue is recognized when the title to the products are transferred to Medtronic, which occurs when the products are shipped from our facility (or FOB shipping point). See Note 3 – Sale of Business , below, for further details. As part of the Restructuring, the Company will focus exclusively on the manufacturing and distribution of the left-heart access Products to Medtronic to continue to generate revenue from such sales and potentially earn the associated earnout payments. The following table sets forth the Company’s revenue for disposables, systems and service/other for the three and nine months ended September 30, 2023 and 2022 (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 (unaudited) (unaudited) Disposables $ 4,069 $ 2,857 $ 11,409 $ 9,402 Systems 563 476 1,254 823 Service/Other 606 311 2,033 1,176 Total revenue $ 5,238 $ 3,644 $ 14,696 $ 11,401 The following table provides revenue by geographic location for the three and nine months ended September 30, 2023 and 2022 (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 (unaudited) (unaudited) United States $ 3,347 $ 1,925 $ 8,720 $ 5,985 Outside the United States 1,891 1,719 5,976 5,416 Total revenue $ 5,238 $ 3,644 $ 14,696 $ 11,401 Inventory Inventory is stated at the lower of cost (first-in, first-out basis) or net realizable value. The Company recorded write-downs for excess and obsolete inventory of $0.3 million and $0.2 million for the three months ended September 30, 2023 and 2022, respectively, and $0.9 million and $2.6 million for the nine months ended September 30, 2023 and 2022, respectively, based on management’s review of inventories on hand, comparisons to estimated future usage and sales, observed shelf-life and assumptions about the likelihood of obsolescence. Accounts Receivable Trade accounts receivable are recorded net of allowances for uncollectible accounts. The Company evaluates the collectability of its accounts receivable based on various factors including historical experience, the length of time the receivables are past due and the financial health of the customer. The Company reserves specific receivables if collectability is no longer reasonably assured. Based upon the assessment of these factors, the Company did not record an allowance for uncollectible accounts as of September 30, 2023 or December 31, 2022. Pursuant to the Asset Purchase Agreement with Medtronic, the Company was eligible to receive the Transfer Earnout, a contingent cash consideration of $17.0 million upon the Company’s initial submission for CE Mark certification. The Company met this condition as of December 31, 2022 and recorded a receivable on the consolidated balance sheets for the year then ended. Medtronic provided full payment in January 2023. See Note 3 - Sale of Business for additional details. In addition, beginning in February 2023, following Medtronic's first commercial sale of the left-heart access Products after the Company's achievement of the OEM Earnout (as such terms are defined in Note 3 - Sale of Business , below), the Company became eligible to earn amounts equal to 100%, 75%, 50% and 50%, respectively, of quarterly Net Sales (as defined in the Asset Purchase Agreement) from sales of the left-heart access Products achieved by Medtronic each year over four years. During the nine months ended September 30, 2023, the Company earned $6.1 million based on Medtronic's left-heart access Products sales and recorded a corresponding receivable on the condensed consolidated balance sheets as of the period then ended. Accounts receivable recorded on the condensed consolidated balance sheets as of September 30, 2023 and December 31, 2022 consists of the following (in thousands): September 30, December 31, (unaudited) Trade accounts receivable $ 2,841 $ 4,085 Earnouts receivable from Medtronic 6,111 17,000 Total accounts receivable $ 8,952 $ 21,085 Employee Retention Credit Receivable The Employee Retention Credit is a refundable U.S. tax credit separate from tax based on income for businesses that continued to pay employees while shut down due to the COVID-19 pandemic or had significant declines in gross receipts from March 13, 2020 to December 31, 2021. The Company applied for the tax credit in 2022 and as of September 30, 2023, the entire $6.8 million claimed tax credit has been refunded to the Company, of which $4.7 million was received during the nine months ended September 30, 2023. Property and Equipment, Net Property and equipment are recorded at cost. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the related assets, generally three Intangible Assets The Company’s intangible assets consist of a license agreement with Biotronik. The Company determines the appropriate useful life of its finite-lived intangible assets by performing an analysis of expected cash flows of the acquired assets. Finite-lived intangible assets are amortized over their estimated useful lives using the straight-line method, which approximates the pattern in which the economic benefits are consumed. Acquired in-process technology is classified as a finite-lived intangible and amortized accordingly. Indefinite-lived intangible assets are tested for impairment at least annually and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Indefinite-lived intangible assets are impaired if their estimated fair values are less than their carrying value. Goodwill Goodwill represents the excess of the purchase price of an entity over the estimated fair value of the assets acquired and liabilities assumed, and it is presented as goodwill in the accompanying condensed consolidated balance sheets. Under ASC 350, Intangibles – Goodwill and Other (“ASC 350”), goodwill is not amortized but is subject to periodic impairment testing. ASC 350 requires that an entity assign its goodwill to reporting units and test each reporting unit’s goodwill for impairment at least on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. In the evaluation of goodwill for impairment, which is performed annually during the fourth quarter, the Company first assesses qualitative factors to determine whether the existence of events or circumstances led to a determination that it was more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company is required to perform the quantitative goodwill impairment test. The Company has one reporting unit. During the nine months ended September 30, 2022, the Company fully impaired its goodwill balance of $12.0 million. Impairment of Long-Lived Assets The Company reviews long-lived assets, including property and equipment and finite-lived intangible assets, for impairment 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 three and nine months ended September 30, 2023 and 2022, the Company determined that there was no impairment of property and equipment or intangible assets. Foreign Currency Translation and Transactions The assets, liabilities and results of operations of Acutus Medical N.V. and Acutus Medical UK Limited are measured using their functional currency, the Euro and British Pound Sterling, respectively, which is the currency of the primary foreign economic environment in which the subsidiaries operate. Upon consolidating these entities with the Company, their assets and liabilities are translated to U.S. dollars at currency exchange rates as of the balance sheet date and their 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 the entities’ 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. Lease Property The Company leases office space in Carlsbad, California as its corporate headquarters and for manufacturing operations. Additionally, it leases office space in Zaventem, Belgium for international operations. 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, credit history, credit rating, 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. In calculating the right-of-use asset and lease liability, the Company elected to combine lease and non-lease components. The Company adopted the policy election to exclude short-term leases having initial terms of twelve months from the initial recognition provisions of ASC 842. See Note 11 - Operating Leases for additional details. Cost of Products Sold Cost of products sold 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. Research and Development Prior to the Restructuring, the Company was actively engaged in new product research and development efforts. Research and development expenses consist primarily of salaries and employee-related costs (including stock-based compensation) for personnel directly engaged in research and development activities, clinical trial expenses, equipment costs, material costs, allocated rent and facilities costs and depreciation. Research and development expenses relating to possible future products are expensed as incurred. The Company also accrues and expenses costs for activities associated with clinical trials performed by third parties as incurred. All other costs relative to setting up clinical trial sites are expensed as incurred. Clinical trial site costs related to patient enrollment are accrued as patients are entered into the trials. Selling, General and Administrative Selling, general, and administrative expenses consist primarily of salaries and employee-related costs (including stock-based compensation) for personnel in sales, executive, finance and other administrative functions, allocated rent and facilities costs, legal fees relating to intellectual property and corporate matters, professional fees for accounting and consulting services, marketing costs and insurance costs. Fair Value Measurements Financial Instruments 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. There were no transfers made among the three levels in the fair value hierarchy for the three and nine months ended September 30, 2023 and 2022. As of September 30, 2023 and December 31, 2022, the Company’s cash (excluding cash equivalents which are recorded at fair value on a recurring basis), restricted cash, accounts receivable, accounts payable and accrued expenses were carried at cost, which approximates the fair values due to the short-term nature of each instrument. The carrying amount of the Company’s long-term debt approximates fair value due to its variable market interest rate and management’s opinion that current rates and terms that would be available to the Company with the same maturity and security structure would be essentially equivalent to that of the Company’s long-term debt. The following tables classify the Company’s financial assets and liabilities measured at fair value on a recurring basis into the fair value hierarchy as of September 30, 2023 and December 31, 2022 (in thousands): Fair Value Measurements as of September 30, 2023 (unaudited) Quoted Significant Significant Total Assets included in: Cash and cash equivalents Money market securities $ 21,019 $ — $ — $ 21,019 Marketable securities at fair value U.S. treasury securities — 2,968 — 2,968 Commercial paper — 10,665 — 10,665 Asset-backed securities — 742 — 742 Total fair value $ 21,019 $ 14,375 $ — $ 35,394 Liabilities included in: Warrant liability $ — $ — $ 1,868 $ 1,868 Total fair value $ — $ — $ 1,868 $ 1,868 Fair Value Measurements as of December 31, 2022 Quoted Significant Significant Total Assets included in: Cash and cash equivalents Money market securities $ 22,700 $ — $ — $ 22,700 Marketable securities at fair value U.S. treasury securities — 26,897 — 26,897 Commercial paper — 14,764 — 14,764 Yankee debt securities — 3,202 — 3,202 Total fair value $ 22,700 $ 44,863 $ — $ 67,563 Liabilities included in: Warrant liability $ — $ — $ 3,346 $ 3,346 Contingent consideration — — 1,800 1,800 Total fair value $ — $ — $ 5,146 $ 5,146 The fair value of the Company’s money market securities is determined using quoted market prices in active markets for identical assets. The fair value for the available-for-sale marketable securities is determined based on valuation models using inputs that are observable either directly or indirectly (Level 2 inputs) such as quoted prices for similar assets, yield curve, volatility factors, credit spreads, default rates, loss severity, current market and contractual prices for the underlying instruments, broker and dealer quotes, as well as other relevant economic measures. Financial Obligations The following table presents changes in Level 3 liabilities measured at fair value for the nine months ended September 30, 2023 (in thousands): Contingent Warrant Liability Balance, December 31, 2022 $ 1,800 $ 3,346 Change in fair value 123 (1,478) Final payment of contingent consideration $ (1,923) $ — Balance, September 30, 2023 (unaudited) $ — $ 1,868 As of September 30, 2023, the fair value of the common stock warrants was estimated using the Black-Scholes option pricing model. The fair value was estimated to be $0.4942 per warrant as of September 30, 2023 and the significant inputs used in the estimation of the fair value were as follows: September 30, 2023 (unaudited) Risk-free interest rate 4.61% Expected term in years 6.75 Expected volatility 85.0% Stock-Based Compensation The Company accounts for all stock-based payments to employees and non-employees, including grants of stock options, restricted stock units ("RSUs"), and restricted stock awards ("RSAs"), to be recognized in the consolidated financial statements based on their respective grant date fair values. The Company estimates the fair value of stock option grants using the Black-Scholes option pricing model. The RSUs and RSAs are valued based on the fair value of the Company’s common stock on the date of grant. The Company expenses stock-based compensation related to stock options, RSUs and RSAs over the requisite service period. All stock-based compensation costs are recorded in cost of pr |
