Summary of Significant Accounting Policies

Reclassifications

The Company has determined that its operating and reportable segments are consistent with its major product groupings which in prior periods included Device Protection, Women’s Health and Cardiovascular. Segment results for the three months ended March 31, 2025, have been recast to conform to the new segment presentation, which now excludes Device Protection due to its divestiture noted above. Refer to the Segment Information in Note 12. Additionally, certain prior period amounts have been reclassified to conform to current period presentation.

Net Loss per Share Attributable to Common Stockholders

Net Income (Loss) per Share

Our common stock has a dual class structure, consisting of Class A common stock, $0.001 par value per share (the “Class A common stock”) and Class B common stock, $0.001 par value per share (the “Class B common stock”). Other than voting rights, the Class B common stock has the same rights as the Class A common stock, and therefore, both are treated as the same class of stock for purposes of the earnings per share calculation. The Company is also authorized to issue up to 10,000,000 shares of preferred stock with a par value of $.001. No shares of preferred stock have been issued or are outstanding as of March 31, 2026 and December 31, 2025. During the year ended December 31, 2025, all outstanding shares of Class B common stock were converted to Class A common stock.

Basic net income (loss) per share is computed by dividing net loss available to each class of shares by the weighted-average number of shares of common stock and participating securities outstanding during the period. Participating securities include common and prefunded warrants. For purposes of the diluted net income (loss) per share calculation, stock options, restricted stock units (“RSUs”) and warrants are considered to be common stock equivalents. In applying the two-class method, the Company has elected an accounting policy to determine whether undistributed earnings are allocated to participating securities by analogy to the ‘control number’ concept in ASC 260. Accordingly, the Company evaluates income (loss) from continuing operations to determine whether participating securities are allocated earnings. Participating securities are not allocated losses as they are not contractually obligated to share in losses. This policy is applied consistently from period to period. See Note 11 for further discussion of net income (loss) per share attributable to common stockholders.

Cash and Cash Equivalents

The Company maintains its cash and cash equivalent balances at banks and financial institutions. The balances are insured up to the legal limit. The Company maintains cash and cash equivalent balances that may, at times, exceed this insured limit. The Company considers cash on hand, demand deposits in a bank, money market funds, and all highly liquid investments with an original maturity of 90 days or less to be cash and cash equivalents.

Inventory

Inventory, consisting of primarily purchased materials, is stated at the lower of cost or net realizable value, with cost determined generally using the average cost method. At each balance sheet date, the Company also evaluates inventory for excess quantities, obsolescence or shelf-life expiration. This evaluation includes an analysis of the Company’s current and future strategic plans, historical sales levels by product, projections of future demand, the risk of technological or competitive obsolescence for products, general market conditions and a review of the shelf-life expiration dates for products. To the extent that management determines there is excess or obsolete inventory or quantities with a shelf life that is too near its expiration for the Company to reasonably expect that it can sell those products prior to their expiration, the Company adjusts the carrying value to the estimated net realizable value.

Leases

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No 2016-02, Leases to increase the transparency and comparability about leases among entities. ASU 2016-02 and certain additional ASUs are now codified as ASC 842, Leases. ASC 842 supersedes the lease accounting guidance in ASC 840 and requires lessees to recognize a lease liability and a corresponding lease asset for virtually all lease contracts. The Company determines if an arrangement contains a lease at inception. Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from that lease. For leases with a term of greater than 12 months, ROU assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. The lease term includes the option to extend the lease when it is reasonably certain the Company will exercise that option. When available, the Company uses the rate implicit in the lease to discount lease payments to present value. In the case that the implicit rate is not available, the Company uses its incremental borrowing rate based on information available at the lease commencement date, including publicly available data for instruments with similar characteristics, to determine the present value of lease payments. The Company combines lease and non-lease elements for office leases.

Warrant Liability

The Company accounts for its warrants in accordance with ASC 815, Derivatives and Hedging – Contracts in Entity's Own Equity, as either liabilities or as equity instruments depending on the specific terms of the warrant agreement. The warrants issued in connection with the September 2023 private placement, June 2024 registered direct offering and 2025 registered direct offering (see Note 8) are classified as liabilities and are recorded at fair value. The warrants are subject to re-measurement at each settlement date and at each balance sheet date and any change in fair value is recognized in Loss (gain) loss on revaluation of warrant liability in the condensed consolidated statements of operations.

Stock-Based Compensation Plans

The Company accounts for its stock-based compensation plans in accordance with FASB Accounting Standards Codification (“ASC”) 718, Accounting for Stock Compensation. ASC 718 requires the measurement and recognition of compensation expense for all stock-based awards made to employees and directors, including employee stock options and restricted stock units. Stock-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense on a straight-line basis over the requisite service period of the entire award.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash. The Company’s cash balances with individual institutions may at times exceed the federally insured limits.

For the three months ended March 31, 2026, there was one customer that represented 14% of the Company’s accounts receivable, and during the year ended December 31, 2025, there was one customer that represented 13% of the Company’s accounts receivable.

Income Taxes

The Company uses the asset and liability method of accounting for income taxes. Deferred income taxes are recorded to reflect the tax consequences on future years for differences between the tax basis of assets and liabilities and their financial reporting amounts at each year-end based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to amounts that are more likely than not to be realized.

The Company is subject to income taxes in the federal and state jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. In accordance with the authoritative guidance on accounting for uncertainty in income taxes, the Company recognizes tax liabilities for uncertain tax positions when it is more likely than not that a tax position will not be sustained upon examination and settlement with various taxing authorities. Liabilities for uncertain tax positions are measured based upon the largest amount of benefit that is more likely than not (greater than 50%) of being realized upon settlement. The Company’s policy is to recognize interest and/or penalties related to income tax matters in income tax expense.
