The authoritative guidance for fair value measurements defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or the most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact, and (iv) willing to transact. The guidance describes a fair value hierarchy based on the levels of input, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, which are the following:

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximated fair value because of the short maturity of these instruments.

Cash and cash equivalents include cash on hand, held at financial institutions and other liquid investments with original maturities of three months or less. At times, these deposits may be more than insured limits. At March 31, 2026, and December 31, 2025, there were no cash equivalents.

Accounts receivable is stated at the amount management expects to collect from outstanding balances. The Company generally does not require collateral to support customer receivables. Management assesses the collectability of outstanding customer invoices and maintains an allowance resulting from the expected non-collection of customer receivables. In estimating this reserve, management considers factors such as industry sector, historical collection experience, customer creditworthiness, specific customer risk, and current and expected general economic conditions. For those customers to whom we extend credit, in accordance with the Current Expected Credit Loss (CECL) model, we make a risk-based evaluation at the point of sale which is then reviewed on both an individual and collective (pool) basis during each reporting period based on ASC 326.

Movements on credit loss accounts are shown below:

Inventories are valued at the lower of cost or net realizable value using the first-in, first-out (FIFO) method. Inventories consist primarily of finished goods and raw materials. We expense costs to maintain certification to cost of goods sold as incurred.

We review inventory on an ongoing basis, considering factors such as deterioration and obsolescence, and future customer demand. We record an allowance for estimated losses when the facts and circumstances indicate that inventories may not be usable or realized when comparing current inventory levels to anticipated demand for our product.  Our reserve for obsolete inventory was $500,000 and $500,000 as of March 31, 2026, and December 31, 2025, respectively.

We account for property and equipment at cost less accumulated depreciation. We compute depreciation using the straight-line method over the estimated useful lives of the assets, generally three to five years. Depreciation commences for equipment, furniture and fixtures and vehicles, once placed in service for its intended use. Leasehold improvements are amortized using the straight-line method over the remaining lease term at the time the asset was placed into service or the service lives of the improvements, whichever is shorter.

We recognize a right-of-use (“ROU”) asset and lease liability for all leases with terms of more than 12 months, in accordance with ASC 842. We utilize the short-term lease recognition exemption for all asset classes as part of our on-going accounting under ASC 842. This means, for those leases that qualify, we will not recognize ROU assets or lease liabilities. Recognition, measurement and presentation of expenses depend upon classification as a finance or operating lease.

As a lessee, we utilize the reasonably certain threshold criteria in determining which options we will exercise. Furthermore, our lease payments are based on index rates with minimum annual increases. These represent fixed payments and are captured in the future minimum lease payments calculation. In determining the discount rate to use in calculating the present value of lease payments, we used our incremental borrowing rate based on the information available at adoption date in determining the present value of lease payments.

We have also elected the practical expedient not to separate lease and non-lease components for all asset classes, meaning all consideration that is fixed, or in-substance fixed, will be captured as part of our lease components for balance sheet purposes. Furthermore, all variable payments included in lease agreements will be disclosed as variable lease expense when incurred. Generally, variable lease payments are based on usage and common area maintenance. These payments will be included as variable lease expense in the period in which they are incurred.

The Company is dependent on a limited number of third-party suppliers for the manufacture of its SteraMist® line of equipment and for the supply of its BIT Solution. This dependence results in concentration of both purchasing activity and accounts payable balances among a small number of vendors.

As of March 31, 2026, two vendors accounted for approximately 54% of total accounts payable, compared to approximately 42% for one vendor as of December 31, 2025.

For the three months ended March 31, 2026, two vendors collectively accounted for approximately 64% of total cost of sales, compared to approximately 50% for the three months ended March 31, 2025. The increase in concentration reflects an increase in equipment sales during the current year period.

The Company remains committed to diversifying its supplier base, though it is substantially dependent on these vendors for its primary product lines. Any disruption to these relationships could have a material adverse effect on the Company's ability to fulfill customer orders and on its results of operations. Refer to Item 1A, Risk Factors, as disclosed in the Company’s Form 10-K, for further discussion of risks related to its reliance on third-party manufacturers and suppliers.

The Company accounts for income taxes in accordance with ASC 740, Income Taxes. Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the tax bases of assets and liabilities.

A significant area of judgment relates to the realization of deferred tax assets, including net operating loss carryforwards and other deductible temporary differences. The Company evaluates the realizability of its deferred tax assets based on available evidence, including historical operating results, projections of future taxable income, and the expected reversal of temporary differences.

Basic net loss per share is computed by dividing our net loss by the weighted average number of shares of common stock outstanding during the period presented. Diluted loss per share is based on the treasury stock method and includes the effect from potential issuance of shares of common stock, such as shares issuable pursuant to the exercise of options and warrants and conversions of preferred stock or debentures. The computation of diluted EPS is similar to the computation of basic EPS except that the numerator may have to adjust for any dividends and income or loss associated with potentially dilutive securities that are assumed to have resulted in the issuance of shares of common stock and the denominator may have to adjust to include the number of additional shares of common stock that would have been outstanding if the dilutive potential shares of common stock had been issued during the period to reflect the potential dilution that could occur from shares of common stock issuable through a contingent shares issuance arrangement, stock options, warrants, or convertible preferred stock. For purposes of determining diluted earnings per common share, the treasury stock method is used for stock options, and warrants, and the if-converted method is used for convertible preferred stock as prescribed in FASB ASC Topic 260. Because of the net loss for the three months ended March 31, 2026 and 2025, the impact of including these in our computation of diluted EPS was anti-dilutive.

Potentially dilutive securities as of March 31, 2026 consisted of 2,508,000 shares of common stock from convertible debentures, 2,604,388 shares of common stock issuable upon exercise of outstanding warrants, 725,042 shares of common stock issuable upon outstanding options, 66,666 shares of common stock issuable upon vesting of restricted stock units and 63,750 shares of common stock issuable upon conversion of outstanding shares of Preferred A Stock (“Convertible Series A Preferred Stock”).

Potentially dilutive securities as of March 31, 2025 consisted of 2,308,000 shares of common stock from convertible debentures, 2,604,388 shares of common stock issuable upon exercise of outstanding warrants, 768,792 shares of common stock issuable upon outstanding stock options and 63,750 shares of common stock issuable upon conversion of outstanding shares of Convertible Series A Preferred Stock.

Options, warrants, RSU’s, preferred stock and shares associated with the conversion of debt to purchase approximately 5.97 million and 5.7 million shares of common stock were outstanding at March 31, 2026 and  March 31, 2025, respectively, but were excluded from the computation of diluted net loss per share at March 31, 2026 and 2025 due to the anti-dilutive effect on net loss per share.

We recognize revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers. We recognize revenue when we transfer promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. To determine revenue recognition, we perform the following five steps: (i) identify the contract with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when or as we satisfy the performance obligations.

We must use judgment to determine: (a) the number of performance obligations and whether they are distinct from one another; (b) the transaction price; and (c) the standalone selling price for each performance obligation for purposes of transaction price allocation.

Title and risk of loss generally pass to our customers upon shipment. Shipping and handling costs charged to customers are included in product revenues, and the associated expenses are treated as fulfillment costs included in cost of revenues. Revenues are reported net of sales taxes collected from customers.

Product revenue includes sales of our standard and customized equipment, BIT Solution and accessories, recognized upon transfer of control to the customer. Service and training revenue includes high-level decontamination engagements, equipment validation and customer training, recognized as the agreed-upon services are rendered.

A portion of our revenue is derived from SIS and CES, which may involve multiple performance obligations including equipment supply, installation, validation and ongoing service. For these arrangements, management exercises significant judgment in identifying and allocating the transaction price among the distinct performance obligations and in determining the point at which control transfers to the customer. Delays in project completion or customer acceptance can affect the timing of revenue recognition.

We record estimated allowances for sales returns using a specific identification method based on subsequent return activity and historical averages. As of March 31, 2026 and December 31, 2025, we recorded allowances of $76,064 and $47,844, respectively.

Disaggregation of Revenue

The following table presents our revenues disaggregated by revenue source (rounded to nearest thousand).

We apply a practical expedient to expense costs as incurred for costs to obtain a contract with a customer when the amortization period would have been one year or less. We generally expense sales commissions when incurred because the amortization period would have been one year or less.

As of March 31, 2026, and December 31, 2025, we had contract balances and unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed in the amounts of $601,130 and $424,032, respectively. The increase in deferred revenue reflects growth in our SIS and CES project pipeline and the timing of project milestones. Changes in assumptions regarding the timing of project completion or customer acceptance could affect the amount and timing of revenue recognized in future periods.

We account for equity compensation expense in accordance with FASB ASC 718, “Compensation—Stock Compensation.” Under the provisions of FASB ASC 718, equity compensation expense is estimated at the grant date based on the award’s fair value.

The valuation methodology used to determine the fair value of options and warrants issued as compensation during the period is the Black-Scholes option-pricing model. The Black-Scholes model requires the use of a number of assumptions including volatility of the stock price, the average risk-free interest rate, and the weighted average expected life of the options. Risk–free interest rates are calculated based on continuously compounded risk–free rates for the appropriate term. The expected term of the Company’s warrants has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” warrants. The dividend yield is assumed to be zero as the Company has never paid or declared any cash dividends on its common stock, par value $0.01 (the “Common Stock”) and does not intend to pay dividends on its Common Stock in the foreseeable future. The Company has elected to account for forfeitures as they occur.

On July 7, 2017, our shareholders approved the Company’s Amended and Restated 2016 Equity Incentive Plan (the “2016 Plan”). The 2016 Plan authorizes the grant of stock options, stock appreciation rights, restricted stock, restricted stock units and performance units/shares. Up to 2,000,000 shares of Common Stock are authorized for issuance under the 2016 Plan. Shares issued under the 2016 Plan may be either authorized but unissued shares, treasury shares, or any combination thereof. Provisions in the 2016 Plan permit the reuse or reissuance by the 2016 Plan of shares of Common Stock for numerous reasons, including, but not limited to, shares of Common Stock underlying canceled, expired, or forfeited awards of stock-based compensation and stock appreciation rights paid out in the form of cash. Equity compensation expense will typically be awarded in consideration for the future performance of services to us. All recipients of awards under the 2016 Plan are required to enter into award agreements with us at the time of the award, and awards under the 2016 Plan are expressly conditioned upon such agreements.

For awards of restricted stock units ("RSUs"), the fair value is determined based on the closing market price of our Common Stock on the grant date. Compensation expense for RSUs is recognized on a straight-line basis over the requisite service (vesting) period.

For the three months ended March 31, 2026, we issued 50,000 shares of common stock out of the 2016 Plan to members of our Board and 33,334 RSUs to Mr. David Vanston, our Chief Financial Officer (see Note 9). As of March 31, 2026, unrecognized stock-based compensation expense related to unvested RSUs was approximately $66,553, which will be recognized over the remaining vesting period through May 30, 2027. There were no shares issued out of the Plan for the three months ended March 31, 2025.

Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and cash equivalents. We maintain cash balances at financial institutions which exceed the current Federal Deposit Insurance Corporation limit of $250,000 at times during the year.

We assess long-lived assets for potential impairments at the end of each year, or during the year if an event or other circumstance indicates that we may not be able to recover the carrying amount of the asset. In evaluating long-lived assets for impairment, we measure recoverability of these assets by comparing the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If our long-lived assets are considered to be impaired, the impairment to be recognized equals the amount by which the carrying value of the asset exceeds its fair market value. We base the calculations of the estimated fair value of our long-lived assets on the income approach. For the income approach, we use an internally developed discounted cash flow model that includes, among others, the following assumptions: projections of revenues and expenses and related cash flows based on assumed long-term growth rates and demand trends; expected future investments to grow new units; and estimated discount rates. We base these assumptions on our historical data and experience, industry projections, micro and macro general economic condition projections, and our expectations. We had no long-lived asset impairment charges for the three months ended March 31, 2026 and 2025.

Advertising and promotional costs are expensed in the period they are incurred. For the three months ended March 31, 2026 and 2025, advertising and promotional expenses included in selling expenses were approximately $23,000 and $31,000, respectively.

Research and development expenses are expensed in the period they are incurred. For the three months ended March 31, 2026 and 2025, research and development expenses were approximately $57,000 and $45,000, respectively.

Pursuant to the guidance in ASC 280, we currently have one reportable business segment due to the fact that we derive our revenue primarily from one product in which 1) The business activities are homogenous in nature, 2) The entire operation faces similar market conditions and risks, 3) There is a high degree of integration in its operations, 4) Internal evaluations of financial results are conducted on a consolidated basis. A breakdown of revenue is presented in “Revenue Recognition” in Note 2 above. See Note 15, Segment Reporting for more details.

For the three months ended March 31, 2026 and 2025, our net loss was approximately $810,000 and $255,000, respectively, and net cash provided by (used in) operations was approximately $296,000 and ($276,000), respectively. As of March 31, 2026, we had approximately $280,000 in cash and cash equivalents, working capital of approximately $394,000, total stockholders' equity of $550, and an accumulated deficit of $58.9 million. These factors raise substantial doubt about our ability to continue as a going concern within one year after the date the financial statements are issued. The consolidated financial statements have been prepared on the basis of continuity of operations, realization of assets and satisfaction of liabilities in the ordinary course of business; no adjustments have been made relating to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should we not continue as a going concern.

Management's Plan to Address Going Concern

Equity Line of Credit and Shelf Registration Statement

In November 2025, we entered into a $20 million Equity Line of Credit ("ELOC") with Hudson Global Ventures, LLC. Our Form S-3 shelf registration statement became effective on December 8, 2025, under which the Company is registered to offer and sell up to $50,000,000 of securities from time to time. Under the ELOC, we may, at our sole discretion, draw down between $25,000 and $2,000,000 per draw, subject to applicable exchange caps. During the three months ended March 31, 2026, we issued 336,147 shares of Common Stock in exchange for aggregate gross proceeds of $149,413. Management believes this facility provides meaningful near-term liquidity, with capacity to provide up to approximately $4 million in the short term, subject to market conditions. Further details are set out in Note 9 to these consolidated financial statements.

Recently issued accounting pronouncements not yet adopted

In November 2024, FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expenses (Subtopic 220-40). In January 2025, ASU No. 2025-01 was issued to clarify the effective date for all public business entities. The ASU requires the disaggregated disclosure of specific expense categories, including purchases of inventory, employee compensation, depreciation, and amortization, within relevant income statement captions. This ASU also requires disclosure of the total amount of selling expenses along with the definition of selling expenses. The ASU is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Adoption of this ASU can either be applied prospectively to consolidated financial statements issued for reporting periods after the effective date of this ASU or retrospectively to any or all prior periods presented in the consolidated financial statements. Early adoption is also permitted. This ASU will likely result in the required additional disclosures being included in our consolidated financial statements once adopted. We are currently evaluating the provisions of this ASU.
