2.        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The summary of significant accounting policies presented below is designed to assist the reader in understanding our consolidated financial statements. Such consolidated financial statements and related notes are the representations of management, who is responsible for their integrity and objectivity. In the opinion of management, these accounting policies conform to accounting principles generally accepted in the United States of America (“U.S. GAAP”) in all material respects and have been consistently applied in preparing the accompanying consolidated financial statements.

Net Sales

Net sales consists of the sale of products and services, as well as shipping and handling billed to our customers and is net of volume rebates and discounts and excludes sales tax.

Revenue Recognition

Revenue from product sales is recognized as promulgated by the Financial Accounting Standards Board (“FASB”) in Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers once our contract(s) with a customer and the performance obligations in the contract have been identified, and the transaction price has been allocated to the performance obligations and revenue is recorded when (or as) we satisfy each performance obligation, generally upon shipment.

Revenue from services, typically non-recurring engineering (“NRE”) services related to the design or customization of a medical device, is typically recognized over time. The customer funding for costs incurred for NRE services is deferred and subsequently recognized as revenue as under-lying products or services are delivered to the customers. Additionally, expenses incurred, up to the customer agreed funding amount, are deferred as an asset and recognized as cost of sales when the under-lying products or services are delivered to the customer. The deferred customer funding and costs result in recognition of deferred costs (asset) and deferred revenue (liability) on our consolidated balance sheets.

One of our customer contracts can give rise to variable consideration due to volume rebates. We estimate variable consideration at the most likely amount we will receive from this customer. Our estimates of variable consideration are based on an assessment of our anticipated performance and all information (historical, current, and forecasted) that is reasonably available to us.

Returns of our product for credit are minimal; accordingly, we do not establish a reserve for product returns at the time of sale.

Cost of Sales

Cost of sales consists primarily of the purchase price of goods and cost of services rendered including freight costs. Cost of sales also includes production labor and overhead costs for all of our manufacturing and assembly operations, which overhead includes all indirect labor and expenses associated with our inspection, warehousing, material planning and quality departments.

Estimated Losses on Product Development Services

Cost and revenue estimates related to the product development service portions of development and supply contracts are reviewed and updated quarterly. An expected loss on development service contracts is recognized immediately in cost of sales. Losses recorded in fiscal 2025 and 2024 related to these services totaled $155,000 and $118,000, respectively.

Due to the complexity of many of the contracts we have undertaken, the cost estimation process requires significant judgment. It is based upon the knowledge and experience of our project managers, engineers, and finance professionals. Factors that are considered in estimating the cost of work to be completed and ultimate profitability of the fixed price product development portion of development and supply contracts include the nature and complexity of the work to be performed, availability and productivity of labor, the effect of change orders, the availability of materials, performance of subcontractors, and expected costs for specific regulatory approvals.

Warranties

Certain of our products are sold with a warranty that provides for repairs or replacement of any defective parts for a period, generally one to two years, after the sale. At the time of the sale, we accrue an estimate of the cost of providing the warranty based on prior experience with such factors as return rates and repair costs, which factors are reviewed quarterly.

The warranty accrual is based on historical costs of warranty repairs and expected future identifiable warranty expenses and is included in accrued expenses in the accompanying consolidated balance sheets. Warranty expenses are included in cost of sales in the accompanying consolidated statements of operations. Changes in estimates to previously established warranty accruals result from current period updates to assumptions regarding repair costs and warranty return rates and are included in current period warranty expense.

Cash and Cash Equivalents

We consider all highly liquid investments with an original maturity of ninety days or less to be cash equivalents. At June 30, 2025 and 2024, cash equivalents consisted of investments in money market funds.

Accounts Receivable

Trade receivables are stated at their original invoice amounts, less an allowance for doubtful portions of such accounts represented by expected credit losses. Management determines the allowance for credit losses based on facts and circumstances related to specific accounts and the age of accounts. As of June 30, 2025 and 2024 we have no allowance for doubtful accounts and expect to fully collect our trade receivable balances. Trade receivables are written off when deemed uncollectible. Recoveries of trade receivables previously reserved are offset against the allowance when received.

Leases

Our operating lease consists solely of our corporate headquarters located in Irvine, California. We do not have any leases classified as financing leases. We classify arrangements meeting the definition of a lease as operating or financing leases, and leases are recorded on the consolidated balance sheets as both a right-of-use asset (“ROU”) and lease liability, calculated by discounting the fixed lease payments over the term of the lease term at the rate implicit in the lease or our incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and the ROU asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the ROU asset result in straight-line rent expense over the lease term. Operating lease assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Variable lease expenses are recorded when incurred. We exclude short-term leases having an initial term of 12 months or less as an accounting policy election, and instead recognize rent expense on a straight-line basis over the term of the lease.

We assess the impairment of ROU assets when an event or change in circumstance indicates that the carrying value of such ROU assets may not be recoverable. If an event or a change in circumstance indicates that the carrying value of an ROU asset may not be recoverable and the estimated fair value attributable to the ROU asset is less than its carrying value, an impairment loss equal to the excess of the ROU’s carrying value over its estimated fair value is recognized.

Deferred Costs

Deferred costs reflect costs incurred related to NRE services under the terms of the related development and/or supply contracts. These costs get recorded to cost of sales in the period that the revenue is recognized.

Inventories

Inventories are stated at the lower of cost (first-in, first-out method) or net realizable value. Cost includes materials, labor, and manufacturing overhead related to the purchase and production of inventories. Reductions to estimated market value are recorded and charged to cost of sales, when indicated based on a formula that compares on-hand quantities to both historical usage and estimated demand as of the measurement date. On an ongoing basis, we evaluate inventory for obsolescence and slow-moving items. This evaluation includes analysis of historical sales and usage, existing demand, as well as specific factors known to management. As of June 30, 2025 and 2024, there was approximately $87,000 and $275,000, respectively, of inventory in-transit from suppliers.

Investments

Investments at June 30, 2025 and 2024, consist of marketable equity securities of publicly held companies. The investments were made to realize a reasonable return, although there is no assurance that positive returns will be realized. Investments are marked to market at each measurement date, with unrealized gains and losses presented separately within other income and expense on the consolidated income statement. All of our investments consist of common stocks of public companies that are either thinly traded or we hold a significant (in excess of 5%) interest in. These investments were subject to a valuation analysis as of June 30, 2025 and 2024.

Long-lived Assets

We review the recoverability of long-lived assets, consisting of the land and building that we own, equipment, and improvements, including leasehold improvements, when events or changes in circumstances occur that indicate carrying values may not be recoverable.

Our building, equipment and improvements are recorded at historical cost and depreciation is provided using the straight-line method over the following periods:

Intangibles

Intangibles consist of legal fees incurred in connection with patent applications. Our patent costs are being amortized over a period of four to seven years. The expense associated with the amortization of the patent costs is recognized in research and development costs.

Income Taxes

We recognize deferred tax assets and liabilities for temporary differences between the financial reporting basis and the tax basis of our assets and liabilities along with net operating losses and tax credit carryovers. Net deferred tax assets or liabilities at both June 30, 2025 and 2024 consisted primarily of basis differences related to unrealized gain/loss related to investments, stock-based compensation, fixed assets, accrued expenses, and inventories. Our deferred tax assets also includes capitalization of our research expenditures as prescribed by the Tax Cuts and Jobs Act. While the One Big Beautiful Bill Act of 2025 (“OBBBA”) was enacted on July 4, 2025, we are continuing to evaluate the impact of OBBBA on our income tax provision and results of operations.

Significant management judgment is required in determining the provision for income taxes, the recoverability of deferred tax assets, and the extinguishment of deferred tax liabilities. Such determination is based on historical taxable income, with consideration given to estimates of future taxable income and the periods over which deferred tax assets will be recoverable and deferred tax liabilities will be extinguished. We record a valuation allowance against deferred tax assets to reduce the net carrying value to an amount that we believe is more likely than not to be realized. When we establish or reduce the valuation allowance against deferred tax assets, the provision for income taxes will increase or decrease, respectively, in the period such determination is made.

Uncertain Tax Positions

We record uncertain tax positions in accordance with Accounting Standards Codification (“ASC”) 740 on the basis of a two-step process whereby (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position, and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority.

Shipping and Handling

Payments from customers for shipping and handling are included in net sales. Shipping expenses, consisting primarily of payments made to freight companies, are included in cost of sales.

Concentration of Credit Risk

Financial instruments that potentially subject us to credit risk consist principally of cash, cash equivalents, and trade receivables. We place our cash and cash equivalents with major financial institutions. At June 30, 2025 and 2024, and throughout the fiscal years then ended, we had deposits in excess of federally insured limits. Credit sales are made to medical device distributors, original equipment manufacturers, and resellers, and sales to such customers account for a substantial portion of our trade receivables. While such receivables are not collateralized, we evaluate their collectability based on several factors including customers’ payment histories.

Segment Reporting

We have identified one business segment which management also considers to be one reporting unit as our Chief Executive Officer (“CEO”) allocates resources, assesses performance, and manages our business as one segment. We have reached this conclusion because 99% of our fiscal 2025 business related to designing, manufacturing, and repairing medical devices. We primarily design, sell, and repair handheld medical devices and accessories. We provide medical devices, NRE and proto-type services, as well as repairs to all our customers and we utilize one machine shop and purchasing team to procure and manufacture all the products that we sell.

The Company’s chief operating decision maker (“CODM”) is our CEO who reviews and evaluates consolidated operating income for purposes of assessing performance, making operating decisions, allocating resources and planning and forecasting for future periods. As our operations are managed at the consolidated level, there are no differences between the measurement of the reportable segment’s profit or loss and our consolidated statements of operations. Further, there are no differences between i) segment revenues and expenses included in the measurement of the reportable segment’s profit or loss and used by the CODM to manage operations and ii) those disclosed elsewhere in the consolidated financial statements. Segment asset measures are not used as a basis for the CODM to evaluate the performance of or to allocate resources.

Compensation Plans

We recognize compensation expense for the share-based awards that vest subject to market conditions under ASC 718, Compensation-Stock Compensation by estimating their fair value using a Monte Carlo simulation. The fair value using a Monte Carlo simulation model is affected by assumptions regarding a number of complex judgments including expected stock price volatility, risk free interest rates, and the forecasted future value and trading volume of our stock. The awards are considered granted for accounting purposes on the date the awards were approved by the Compensation Committee of our Board of Directors and we recognize compensation expense, based on the estimated fair value of the award, on a straight-line basis over the requisite service period.

Use of Estimates

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Our operations are affected by numerous factors including market acceptance of our products, supply chain disruptions, changes in technologies, and new laws, government regulations, and policies. We cannot predict what impact, if any, the occurrence of these or other events might have on our operations. Significant estimates and assumptions made by management include, but are not limited to, revenue recognition, share-based compensation, the allowance for credit losses, accrued warranty expense, investments, inventory valuation, the carrying value of long-lived assets, and the recoverability/extinguishment of deferred income tax assets and liabilities.

Basic and Diluted Per Share Information

Basic per share amounts are computed on the basis of the weighted-average number of common shares outstanding during each period presented. Diluted per share amounts assume the issuance of all potential common stock equivalents, consisting of outstanding stock options and performance awards as discussed in Note 11, unless the effect of such exercise is to increase income, or decrease loss, per common share.

Fair Value Measurements

Fair value is measured based on the prices that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are based on a three-tier hierarchy that prioritizes the inputs used to measure fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions.

Cash and cash equivalents: The carrying value of cash and cash equivalents is considered to be representative of their fair values based on the short-term nature of these instruments. As such, cash and cash equivalents are classified within Level 1 of the valuation hierarchy.

Investments: Investments consist of marketable equity securities of publicly held companies. Due to either the thinly traded nature of these stocks or our significant ownership percentage, in excess of 5% of shares outstanding, all of our investments are classified within Level 2 of the valuation hierarchy as of June 30, 2025 and 2024. The fair value of all of our investments at June 30, 2025 and 2024 was based upon a valuation analysis.

Although the methods above may produce a fair value calculation that may not be indicative of the net realizable value or reflective of future fair values, we believe our valuation methods are appropriate.

Advertising

Advertising costs are charged to selling or general and administrative expense as incurred and amounted to $78,000 and $14,000 for the fiscal years ended June 30, 2025 and 2024, respectively.

Reclassifications

Certain prior year amounts have been reclassified to conform to the current year presentation.

Recently Adopted Accounting Pronouncements

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes: Improvements to Income Tas Disclosures (Topic 740). ASU 2023-09 expands the existing rules on income tax disclosures. This update requires entities to disclose specific categories in the tax rate reconciliation, provide additional information for reconciling items that meet a quantitative threshold and disclose additional information about income taxes paid on an annual basis. We adopted ASU 2023-09 effective July 1, 2024, and the adoption did not have a material impact on our financial statements.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting: Improvements to Reportable Segment Disclosures (Topic280) which expands disclosure requirements to require entities to disclose significant segment expenses that are regularly provided to or easily computed from information regularly provided to the chief operating decision maker. This update also requires all annual disclosures currently required by Topic 280 to be disclosed in interim periods. We adopted ASU 2023-07 effective June 30, 2025, and the adoption did not have a material impact on our financial statements.

Recently Issued and Not Yet Adopted Accounting Pronouncements

In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2024-03, Disaggregation of Income Statement Expenses. The ASU’s purpose is to improve the disclosures about a public business entity’s expenses and address requests from investors for more detailed information about the types of expenses (including purchases of inventory, employee compensation, depreciation, amortization, and depletion) in commonly presented expense captions (such as cost of sales, selling, general and administrative, and research and development). This ASU is effective for fiscal years beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, with early adoption permitted. We are currently evaluating these new expanded disclosure requirements, but this standard will not impact our results of operations or financial position.
