Note 3 – Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”), and pursuant to the accounting and disclosure rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). Certain information and note disclosures have been condensed or omitted pursuant to such rules and regulations. The unaudited condensed financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair presentation of the period presented. The results of operations for the three months ended March 31, 2025 are not necessarily indicative of the results to be expected for the year ending December 31, 2025, or for other future periods.

These interim unaudited condensed financial statements should be read in conjunction with the audited financial statements and notes thereto for the fiscal year ended December 31, 2024 included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, filed with the SEC on February 27, 2025 (“the 2024 Annual Report”). The accounting policies used in preparing these interim unaudited condensed financial statements are consistent with those described in the 2024 Annual Report.

Reclassifications

Certain reclassifications have been made to the fiscal year 2024 financial statements to conform to the 2025 presentation. The Company reclassified certain expenses between research and development and general and administrative expenses. The amounts were not considered material to the condensed financial statements. The reclassifications had no impact on total assets, total liabilities, or stockholders’ equity (deficit).

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the financial statements as well as the reported expenses during the reporting periods.

The Company’s significant estimates and assumptions include the valuation of stock-based compensation instruments, recognition of revenue, inventory valuation, fair value of warrant liabilities and the valuation allowance on deferred tax assets. Some of these judgments can be subjective and complex, and, consequently, actual results may differ from these estimates. Although the Company believes that its estimates and assumptions are reasonable, they are based upon information available at the time the estimates and assumptions were made. Actual results could differ from those estimates.

Cash, Cash Equivalents and Restricted Cash

The Company considers all short-term, highly liquid investments with an original maturity at the date of purchase of three months or less to be cash equivalents. The Company maintains cash balances that may be uninsured or in deposit accounts that exceed Federal Deposit Insurance Corporation limits. The Company maintains its cash deposits with major financial institutions.

Warrants

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 480, “Distinguishing Liabilities from Equity” (“ASC 480”) and ASC 815, “Derivatives and Hedging” (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s common stock, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.

Note 3 – Summary of Significant Accounting Policies, continued

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 required to be recorded as a liability at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss on the statements of operations. The fair value of the warrants is estimated using an appropriate valuation model. Such warrant classification is also subject to re-evaluation at each reporting period.

Offering costs associated with warrants classified as liabilities are expensed as incurred and are presented as offering cost related to warrant liability in the statement of operations. Offering costs associated with the sale of warrants classified as equity are charged against the proceeds received.

Fair Value

The Company follows ASC 820, “Fair Value Measurements” (“ASC 820”), which establishes a common definition of fair value to be applied when US GAAP requires the use of fair value, establishes a framework for measuring fair value, and requires certain disclosure about such fair value measurements.

ASC 820 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about what market participants would use in pricing the asset or liability based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the reliability of inputs as follows:

Because of the uncertainties inherent in the valuation of assets or liabilities for which there are no observable inputs, those estimated fair values may differ significantly from the values that may have been used had a ready market for the assets or liabilities existed.

The carrying amounts of the Company’s financial assets and liabilities, such as cash, cash equivalents, prepaid expenses and other current assets, and accounts payable and accrued expenses, are an approximate of their fair values because of the short maturity of these instruments. The carrying amounts of the Company’s short-term debt and lease liabilities approximate fair value due to the market interest rates that these obligations bear and interest rates currently available to the Company. The Company’s warrant liability recognized at fair value on a recurring basis is a level 3 measurement (see Note 13 – Fair Value Measurements).

Revenue Recognition

The Company follows ASC 606, “Revenue from Contracts with Customers” (“Topic 606”).

In accordance with Topic 606, the Company recognizes revenue using the following five-step approach:

Note 3 – Summary of Significant Accounting Policies, continued

The Company’s revenue consists of its single segment of wireless charging system solutions. The wireless charging system revenue consists of revenue from product development projects and production-level systems. During the three months ended March 31, 2025 and 2024, the Company recognized $0.3 million and $0.1 million in revenue, respectively.

The Company records revenue associated with product development projects that it enters into with certain customers. In general, these product development projects are complex, and the Company does not have certainty about its ability to achieve the project milestones. The achievement of a milestone is dependent on the Company’s performance obligation and requires acceptance by the customer. The Company recognizes this revenue at the point in time at which the performance obligation is met. The payment associated with achieving the performance obligation is generally commensurate with the Company’s effort or the value of the deliverable and is nonrefundable. Any deferred revenue is recognized upon achievement of the performance obligation or expiration of a support agreement.

Accounts Receivable

The Company reviews its receivables for collectibility based on historical loss patterns, aging of the receivables, and assessments of specific identifiable client accounts considered at risk or uncollectible and provides allowances for potential credit losses, as needed. The Company also considers any changes to the financial condition of its clients and any other external market factors that could impact the collectibility of the receivables in the determination of the allowance for credit losses. Based on these assessments, the Company did not record a provision for credit losses on its accounts receivable as of March 31, 2025 and December 31, 2024.

The Company follows ASC Topic 310, Receivables (“Topic 310”) to account for transactions related to factoring accounts receivable. The Company did not have a factoring agreement during the three months ended March 31, 2025 and 2024.

Inventory

Inventory is stated at the lower of cost or net realizable value. Net realizable value is calculated at the end of each reporting period and adjustment, if needed, is made. At the point of loss recognition, a new lower cost basis for that inventory is established and subsequent changes in facts and circumstances do not result in the restoration or increase in the new cost basis.

Research and Development

Research and development expenses are charged to operations as incurred. The Company incurred research and development costs of $1.2 million and $2.2 million during the three months ended March 31, 2025 and 2024, respectively.

Stock-Based Compensation

The Company accounts for equity instruments issued to employees, board members and contractors in accordance with accounting guidance that requires awards to be recorded at their fair value on the date of grant and amortized over the vesting period of the award. The Company amortizes compensation costs on a straight-line basis over the requisite service period of the award, which is typically the vesting term of the equity instrument issued.

Under the ESPP, employees purchased a limited number of shares of the Company’s common stock at a 15% discount from the lower of the closing market prices measured on the first and last days of each half-year period. The Company recognized stock-based compensation expense for the fair value of the purchase options, as measured on the grant date. The Company discontinued the ESPP as of January 21, 2025.

Income Taxes

The Company follows the asset and liability method of accounting for income taxes under ASC Topic 740, Income Taxes (“ASC 740”). Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between financial statement carrying amounts and the tax basis of existing assets and liabilities and net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply in the years in which those tax assets and liabilities are expected to be realized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. A valuation allowance is established if it is more likely than not that all or a portion of the deferred tax asset will not be realized.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company continues to assess the need for a valuation allowance on the deferred tax assets by evaluating both positive and negative evidence that may exist. Any adjustment to the valuation allowance on deferred tax assets would be recorded in the statements of income for the period that the adjustment is determined to be required.

The Company accounts for uncertain tax position in accordance with ASC 740. Tax benefits are recognized only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. A liability for “unrecognized tax benefits” is recorded for any tax benefits claimed in the Company’s tax returns that do not meet these recognition and measurement standards. The guidance from ASC 740, “Income Taxes” also discusses the classification of related interest and penalties on income taxes. The Company’s policy is to record interest and penalties on uncertain tax positions as a component of income tax expense.

Net Loss Per Common Share

Basic net loss per share is computed by dividing net loss available to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed using the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options and warrants (using the treasury stock method) and the vesting of RSUs and PSUs. The computation of diluted loss per share excludes potentially dilutive securities of 1,872,325 and 1,546,213, as outlined in the table below, for the three months ended March 31, 2025 and 2024, respectively, because their inclusion would be anti-dilutive.

​

​

For the three months ended March 31, 2025, the table above includes 1,020,409 warrants expiring on February 20, 2029, which have an exercise price of $1.84 per share and 412,500 warrants expiring on March 28, 2029, which, as of March 31, 2025, have an exercise price of $0.29 per share. For the three months ended March 31, 2024, the table above includes 1,029,409 warrants expiring on February 20, 2029, which have an exercise price of $1.84 per share and 412,500 warrants expiring on March 28, 2029, which, as of March 31, 2024, had an exercise price of $1.66 per share.

¹ The weighted average number of common shares outstanding as of March 31, 2024 included the weighted average effect of the 450,409 pre-funded warrants issued in connection with a registered direct offering the Company entered into on February 15, 2024 (see Note 10 – Capital Stock and Warrants) because the exercise of such warrants required nominal consideration ($0.001 per share exercise price for each pre-funded warrant). As of March 31, 2024, none of the pre-funded warrants had been exercised; therefore, all 450,409 outstanding pre-funded warrants as of that date are not included in the table above. As of March 31, 2025, these pre-funded warrants have been exercised.

Property and Equipment

The Company currently uses the following expected life terms for depreciating property and equipment: computer software – 1-2 years, computer hardware – 3 years, furniture and fixtures – 7 years, leasehold improvements – shorter of estimated life or remaining life of the lease.

Leases

The Company determines if an arrangement is a lease at the inception of the arrangement. The Company applies the short-term lease recognition exemption and recognizes lease payments in profit or loss at lease commencement for facility or equipment leases that have a lease term of 12 months or less and do not include a purchase option whose exercise is reasonably certain. Operating leases are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities.

ROU assets represent the right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are measured and recorded at the later of the adoption date, January 1, 2019, or the service commencement date based on the present value of lease payments over the lease term. The Company uses the implicit interest rate when readily determinable; however, most leases do not establish an implicit rate, so the Company uses an estimate of the incremental borrowing rate based on the information available at the time of measurement. Lease expense for lease payments is recognized on a straight-line basis over the lease term. See Note 8 – Commitments and Contingencies, Operating Leases for further discussion of the Company’s operating leases.

Segments

The Company has one operating segment and one reportable segment as its chief operating decision maker (“CODM”), who is its Chief Executive Officer and Chief Financial Officer, reviews financial information on a regular basis for purposes of allocating resources and evaluating financial performance. The CODM also reviews and utilizes functional expenses, such as cost of revenue, research and development, sales and marketing and general and administrative, to manage the Company’s operations. All long-lived assets are located in the United States and substantially all revenue is attributed to customers based in the United States.

Recent Accounting Pronouncements, Not Yet Adopted

In December 2023, the FASB issued Accounting Standards Update (“ASU”) No. 2023-09, “Income Taxes” (“Topic 740”), Improvements to Income Tax Disclosures. This standard is intended to enhance the transparency and usefulness of income tax disclosures to better assess how an entity’s operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. This standard is effective for the Company’s annual fiscal period beginning January 1, 2025. The Company does not believe that the adoption of this standard will have a material impact on the Company’s financial statements and related disclosures.

In November 2024, the FASB issued ASU No. 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” This ASU requires the disaggregation of certain expenses in the notes to the financial statements, to provide enhanced transparency into the expense captions presented on the face of the income statement. This ASU is effective on a prospective basis for fiscal years beginning after December 15, 2026 and for interim periods beginning after December 15, 2027, with early adoption permitted. This ASU may be applied either prospectively or retrospectively. The Company is currently evaluating the impact of the new standard on the financial statements and related disclosures.

Management has reviewed other recently issued accounting pronouncements issued or proposed by the FASB and does not believe any of these accounting pronouncements has or will have a material impact on the condensed financial statements.
