Significant Accounting Policies (Policies)

12 Months Ended

Apr. 30, 2025

The accompanying consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and generally accepted accounting principles in the United States of America (“US GAAP”) and include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company’s reporting currency is the U.S. dollar.

Certain prior period amounts in the consolidated statements of cash flows have been reclassified to conform to the current period presentation.

Use of Estimates

The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of expenses during the reporting period. Estimates are required as part of determining the collectability of lease payments for revenue recognition, estimated useful lives of property and equipment, losses for unreturned property and equipment, share-based compensation expense, fair value of warrants and valuation allowance for deferred tax assets.

The Company bases its estimates on historical experience and other market-specific or relevant assumptions that it believes to be reasonable under the circumstances. Actual results could differ from those estimates.

Cash, Cash Equivalents and Restricted Cash

The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents are recorded at cost, which approximates fair value. Restricted cash consists of amounts related to the Company’s office lease agreement and credit card collateralization. In lieu of a cash security deposit, the landlord required an irrevocable standby letter of credit upon execution of the lease be

maintained throughout the term of the lease agreement in the amount of $109 as of April 30, 2025 and 2024. The Company also had restricted cash of $225 for credit card collateralization as of April 30, 2025 and 2024.

Disposable Medical Equipment Supplies

Disposable medical equipment supplies consist of equipment parts, consumables, and associated product supplies that are expensed to the cost of revenue at the time of order delivery to the patient or first use. Disposable medical equipment supplies are valued at cost.

Accounts Receivable

Accounts receivable and net revenues are based on contractually agreed-upon rates for leases for the ASSURE© System, reduced by contractual adjustments. Inherent in these estimates is the risk that they will have to be revised or updated as additional information becomes available. The complexity of third-party billing arrangements and laws and regulations governing Medicare may result in adjustments to amounts originally recorded.

The Company performs a periodic analysis to review the valuation of accounts receivable and collectability of outstanding balances. These estimates are determined utilizing historical realization data under a portfolio approach which is then assessed by management to evaluate whether adjustments should be made based on accounts receivable aging trends, other operating trends, and relevant business conditions such as governmental and managed care payor claims processing procedures.

The Company records a reserve for estimated probable losses as part of net revenue adjustments in reporting revenue at an expected collectable amount based on the total portfolio of receivables for which collectability has been deemed probable. Accounts receivable is presented on the consolidated balance sheets net of the adjustments.

Receivables are considered past due when not collected by established due dates. Specific patient balances are written off after collection efforts have been followed and the account has been determined to be uncollectible. Changes to reserve estimate impacts are recorded as an adjustment to net revenue in the period during which changes in circumstances support a change to the estimate. The estimates of the allowance for uncollectible accounts receivable were $3,193 and $500 as of April 30, 2025 and 2024, respectively.

Property and Equipment

Property and equipment consist of medical rental equipment, test equipment, computer software and equipment, and leasehold improvements. Medical rental equipment used in the delivery of the ASSURE® WCD system consists of therapy cables, batteries, battery chargers, assistants and WCD monitors, all of which have different useful lives. Upon completion of use by a patient, medical rental equipment is returned to the Company’s third-party manufacturing and supply partner and inspected, tested and recertified for use by another patient. When not in use by patients, medical rental equipment resides with the Company’s third-party manufacturing and supply partner, at third-party warehouses or with the Company’s territory managers. Physical counts of components are conducted at least annually at the third-party manufacturing and supply partner locations and at least quarterly at other locations.

Property and equipment are stated at cost less accumulated depreciation. Depreciation of medical rental equipment commences at the date when it becomes available for service, which represents the date that the asset is ready for intended use by the patients and continues through the estimated useful life of the asset. Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized. Expenditures for maintenance and repairs, including planned major maintenance activities, are expensed as incurred.

Property and equipment are depreciated using the straight-line method based on the following estimated useful lives:


	April 30, 2025	April 30, 2024
Asset Classification	Estimated Useful Lives	Estimated Useful Lives
Computer software and equipment	3 years	3 years
Test equipment	5 years	5 years
Leasehold improvements	Lesser of useful life or lease-term	Lesser of useful life or lease-term
Medical rental equipment	2 - 8 years	1.5 - 7 years

During the year ended April 30, 2025, the estimated useful life of the medical rental equipment asset class was changed prospectively from 1.5 - 7 years to 2 - 8 years. This change was the result of an FDA approval allowing therapy cables to be repaired up to three times, which increased the estimated useful life of this component from two

years to eight years. The impact was a reduction of depreciation expense, which is included within cost of revenue, by $1,208 in the year ended April 30, 2025, compared to if the useful life of therapy cables had remained at two years. In addition, during the year ended April 30, 2025, the estimated useful lives of batteries was extended from two years to six years and was applied prospectively. This change was a result of the better-than-expected performance of the batteries. The impact was a reduction of depreciation expense, which is included within cost of revenue, by $198 in the year ended April 30, 2025, compared to if the useful life of batteries had remained at two years. This change in estimated useful life reduced net loss and comprehensive loss by the same amount.

When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts, and any resulting gain or loss is recognized in the consolidated statements of operations and comprehensive loss for the period.

Deposits

Deposits represent advance payments to contracted suppliers for medical rental equipment. These payments are classified as long-term assets in the consolidated balance sheets.

Leases

The Company determines if an arrangement is a lease at inception and on the lease commencement date, the Company recognizes an asset for the right to use a leased asset and a liability based on the present value of remaining lease payments over the lease term.

The Company determines whether a contract contains a lease at the inception of a contract. If the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration, the Company considers the contract to contain a lease.

The Company determines whether a contract conveys the right to control the use of an identified asset for a period of time if the contract contains both the right to obtain substantially all of the economic benefits from use of the identified asset and the right to direct the use of the identified asset.

The Company’s leases do not provide an implicit rate. As such, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.

Lease and non-lease components are combined for all leases. The measurement of lease right-of-use assets and liabilities includes amounts related to lease payments made prior to the lease commencement date, incentives from landlords received by the Company for signing a lease, including tenant improvement allowances or deferred lease credits paid to the Company by landlords, fixed payments related to lease components, such as rent escalation payments schedules at the lease commencement date, and fixed payments related to non-lease components, such as taxes, insurance and maintenance costs. The measurement of lease right-of-use assets and liabilities excludes amounts related to variable payments related to lease components, such as contingent rent payments.

Variable payments related to non-lease components, such as taxes, insurance and maintenance costs, are expensed as incurred in the consolidated statements of operations and comprehensive loss. The Company has elected not to recognize right-of use-assets and lease liabilities for leases with a term of twelve months or less. Lease costs for short-term leases are recognized on a straight-line basis over the lease term.

Certain of the Company’s leases may include options to extend the lease or to terminate the lease. The Company assesses these leases and, depending on the facts and circumstances, has not included these options in the measurement of the Company’s lease right-of-use assets and liabilities since extending the lease under an option is not reasonably certain of such option being exercised.

Non-cash amortization related to the lease right-of-use assets and liabilities is calculated on a straight-line basis over the lease term and is reflected in research and development expenses and selling, general and administrative expense in the consolidated statements of operations and comprehensive loss. Operating lease payments are classified as cash flows from operating activities in the consolidated statements of cash flows.

Impairment of Long-Lived Assets

The Company periodically reviews its long-lived assets, including property and equipment and right-of-use assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable.

The Company compares the carrying value of the long-lived assets (asset group) with the estimated future net undiscounted future cash flows expected to result from the use of the assets (asset group), including cash flows from disposition. An impairment loss is measured as the amount by which the carrying value exceeds the fair value of the long-lived assets (asset group). No impairment of long-lived assets was recorded during the years ended April 30, 2025 and 2024.

Warrant Liabilities

The Company accounts for certain warrants as liabilities in accordance with ASC 815-40, Derivatives and Hedging. The warrants are presented as a warrant liability in the consolidated balance sheets and are measured at fair value, with gains or losses recognized in the consolidated statements of operations and comprehensive loss.

Revenue

The Company generates revenue from the leases of ASSURE© System, which consists of a Wearable Cardioverter Defibrillator combined with a proprietary digital healthcare platform, to at-risk patients for a fixed amount on a month-to-month basis. The lease payments generally consist of the contracted amounts based on reimbursement arrangements with third-party payors including Medicare, Medicaid and private commercial payors, and/or certain patient co-payments. The patient has the right to cancel the lease at any time during the rental period.

The equipment leases are classified as operating leases at lease commencement, and the Company recognizes the revenue associated with ASSURE© rentals in accordance with Accounting Standards Codification Topic 842, Leases (“ASC Topic 842”). The Company elected the practical expedient provided under ASC Topic 842 to combine the lease of ASSURE© System with the non-lease components, which includes the digital healthcare platform. The ASSURE© System is expected to be the predominant component and, as a result, the Company accounts for the combined revenue components under ASC Topic 842. Revenue is recognized on a straight-line basis over the contractual non-cancellable lease term, which is one month, when collectability of the lease payments is deemed to be probable. If collectability of the lease payments is not deemed to be probable, the lease income is limited to the lesser of the income that would have been recognized if collectability was probable or the lease payments collected. Collectability of all lease payments, which includes amounts reimbursed by third-party payors and/or amounts covered by the patient, is assessed for each contract upon lease commencement and is subject to subsequent reassessment throughout the lease term, as necessary.

Due to the nature of the industry and the reimbursement environment in which the Company operates, the Company periodically evaluates the need to record a general reserve under ASC 450, Contingencies, for a portfolio of operating lease receivables that are probable of collection. Inherent in the reserve estimates is the risk that they will have to be revised or updated as additional information becomes available. Specifically, the complexity of many third-party billing arrangements and the uncertainty of reimbursement amounts for certain services from certain payors may result in adjustments to amounts originally recorded. Such adjustments are expected to be identified and recorded at the point of cash application or claim denial.

Cost of Revenue

Cost of revenue consists of direct material, labor and rental equipment costs and indirect costs related to rental performance of ASSURE© System. It includes the cost of disposable WCD device components, depreciation cost of medical rental equipment reusable components, shipping, and order fulfillment costs, as well as other indirect costs incurred to support the manufacture and medical rental equipment delivery to and ongoing support for the patient’s costs incurred in connection with providing the ASSURE© System to the patients.

Deferred IPO Offering Costs

The Company capitalized as deferred offering costs all direct and incremental legal, professional and other third-party fees incurred in connection with the Company’s IPO within long-term assets. The Company recorded $5,398 in deferred offering costs through the IPO in March 2025 (see Note 1 “The Company”). The deferred offering costs were offset against the IPO proceeds upon closing of the IPO and were no longer deferred. As of April 30, 2025, $1,875 of the IPO offering costs were in accounts payable and accrued expenses.

Income Taxes

The Company accounts for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established if it is more likely than not that some, or all of the net deferred tax assets will not be realized.

The Company recognizes the effect of income tax positions only if it is more likely than not that the tax position will be sustained upon examination by the tax authorities. Recognized income tax positions are measured at the largest amount that has a greater than 50% likelihood of being recognized. Changes in recognition or measurement are reflected in the period in which the change in judgement occurs.

Research and Development

Research and development expenses consist of salaries and related benefits of product development personnel, prototype materials and other expenses related to the development of new products. Research and development expenses are expensed as incurred.

Patent Costs

Costs related to filing and pursuing patent applications are expensed as incurred, as recoverability of such expenditures is uncertain. Patent-related legal costs are included as a component of selling, general and administrative expenses.

Share-Based Compensation

The Company accounts for share-based compensation for employee and non-employee awards in accordance with ASC 718, Compensation - Stock Compensation. ASC 718 requires the recognition of compensation expense using a fair value-based method for costs related to all share-based awards, including stock options.

Share-based compensation expense for share-based payments is measured at the grant date based on the fair value of the award and recognized as compensation expense over the period of service. The Company uses the Black-Scholes option pricing model to determine the fair value of share-based payments. The model requires various assumptions involving the judgement of management, including the fair value of common units or common shares, volatility in price, time to liquidity (prior to the IPO) and risk-free interest rate. As the Company did not have sufficient trading history for share-based awards issued prior to the IPO, the expected volatility was derived from the average historical volatilities of several comparable public companies within the Company’s industry over a period equivalent to the expected term of the share-based awards. The Company will continue to analyze the volatility assumptions as additional data for the Company’s Common Share becomes available. Due to the lack of historical exercise history, the expected term of the Company’s stock options is determined using the “simplified” method. The risk-free interest rate is rate is based on the U.S. Treasury yield in effect at the time of grant for zero-coupon U.S. treasury notes with maturities approximately equal to expected term of the stock options. Expected dividend yield is zero based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future.

The Company classifies share-based compensation expense in its statements of operations and comprehensive loss in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified.

Payments on Behalf of Shareholder

During the year ended April 30, 2025, and 2024, the Company paid administrative costs to third parties on behalf of one of its shareholders of $4,878 and $799, respectively. The payments to third parties on behalf of the Company’s shareholder were recorded as a deemed dividend in the consolidated statements of changes in redeemable preferred stock and shareholders’ equity (deficit).

Concentrations of Risk

Credit Risk

Financial instruments which potentially subject the Company to significant concentrations of credit risk consist primarily of cash. The Company’s cash is mainly held in financial institutions. Amounts on deposit may at times exceed federally insured limits. The Company has not experienced any losses on its deposits of cash and does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. Further, the Company holds a small cash balance in its account located in the Cayman Islands, which is not insured.

Business Risk

The Company relies and expects to continue to rely on a small number of vendors to manufacture supplies, materials, and rental equipment for its use in the commercial product and the clinical trial programs. These programs could be adversely affected by a significant interruption in these manufacturing services.

Customer Risk

The Company earns revenues by seeking reimbursement for the product from governmental healthcare programs and private health insurance companies, including the federal Medicare program. If the Medicare program were to slow payments of the receivables for any reason, the Company would be adversely impacted. In addition, both governmental healthcare programs and private health insurance companies may seek ways to avoid or delay reimbursement, which could adversely affect the Company’s cash flow and revenues.

Segment Information

The Company has a single operating and reportable segment. The Company has determined that its Chief Executive Officer is its chief operating decision maker. The Company’s Chief Executive Officer reviews financial information presented on a consolidated basis and in a consistent manner with that is included in the consolidated statements of operations and comprehensive loss for purposes of assessing performance and making decisions on how to allocate resources. As the Company operates as one operating segment, all required segment financial information, such as revenues and significant operating expenses, is found in the accompanying consolidated financial statements. For the periods presented, all of the Company’s long-lived assets were located in the United States, and all revenues from leasing of ASSURE© System devices to patients were earned in the United States. The accounting policies for segment reporting are the same as for the Company as a whole.

The chief operating decision maker utilizes the Company’s financial information such as net loss and comprehensive loss derived from revenues and operating expenses included in the Company forecast, performance metrics, and budget versus actual analyses for purposes of evaluating financial performance and how to best allocate resources when developing and reviewing the annual budget to achieve the Company’s long-term objectives. Significant expenses within loss from operations include cost of revenue, research and development, selling, general and administrative expenses, which are each separately presented on the Company’s Consolidated Statements of Operations and Comprehensive Loss.

Fair Value of Financial Instruments

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants as of the measurement date. There are three levels of inputs that may be used to measure fair value:

•

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities

•

Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability

•

Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).

Comprehensive Loss

Comprehensive loss consists of net loss and other gains or losses affecting shareholders’ equity that, under accounting principles generally accepted in the United States of America, are excluded from net loss. For the years ended April 30, 2025 and 2024, there were no items which qualify as components of other comprehensive loss and therefore, the Company’s comprehensive loss was the same as its reported net loss.

Recently Adopted Accounting Pronouncements and Accounting Pronouncements Not Yet Adopted

Recently Adopted Accounting Pronouncements

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU No. 2023-07”). ASU 2023-07 requires that an entity disclose significant segment expenses, a description of “other segment items,” and the title and position of the chief operating decision maker along with an explanation of how the reported segment profit or loss is assessed and allocated. The amendments in this ASU were applied retrospectively for all prior periods presented in the financial statements. The Company adopted ASU 2023-07 during the year ended April 30, 2025. The adoption of the amendments in ASU 2023-07 impacted the Company’s disclosures in the notes to the consolidated financial statements and did not have a material impact on its consolidated balance sheets, results of operations or cash flows.

Accounting Pronouncements Not Yet Adopted

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which enhances transparency and decision usefulness of income tax disclosures, primarily related to the income tax rate reconciliation and income taxes paid information. The guidance is effective for private business entities for annual reporting periods beginning after December 15, 2025. The Company does not anticipate a material impact to the required financial statement disclosure as a result of this ASU.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40) (“ASU 2024-03”), requiring disclosure in the notes to the financial statements for specified information about certain costs and expenses. ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027; however early adoption is permitted and can be applied either prospectively or retrospectively. The Company is evaluating the impact that this ASU will have on its financial statement disclosures.

The Company has reviewed other recent accounting pronouncements and concluded that they are either not applicable to the business, or that no material effect is expected on the consolidated financial statements as a result of future adoption.
