2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission requires management to make estimates and judgments that affect the amounts reported in the financial statements and accompanying notes. Estimates are used for, but not limited to, the valuation allowance of net, deferred taxes. The results of these assumptions provide the basis for making estimates about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results could differ from these estimates.

Revenue Recognition

The Company recognizes revenue in accordance with “ASC” Topic 606, “Revenue from Contracts with Customers”. The Company accounts for a customer contract when both parties have approved the contract and are committed to perform their respective obligations, each party’s rights can be identified, payment terms can be identified, the contract has commercial substance, and it is probable that the Company will collect substantially all of the consideration to which it is entitled. Revenue is recognized when, or as, performance obligations are satisfied by transferring control of a promised product or service to a customer.

The Company determines revenue recognition through the following steps:

The Company has made the following accounting policy elections and elected to use certain practical expedients, as permitted by the Financial Accounting Standards Board (“FASB”), in applying ASC Topic 606: 1) All revenues are recorded net of returns, allowances, customer discounts, and incentives; 2) Although sales and other taxes are immaterial, the Company accounts for amounts collected from customers for sales and other taxes, if any, net of related amounts remitted to tax authorities; 3) the Company expenses costs to obtain a contract as they are incurred if the expected period of benefit, and therefore the amortization period, is one year or less; 4) the Company accounts for shipping and handling activities that occur after control transfers to the customer as a fulfillment cost rather than an additional promised service and these fulfillment costs fall within selling expenses; 5) the Company is always considered the principal and never an agent, because it has full control and responsibility until title is transferred to the customer and 6) the Company does not assess whether promised goods or services are performance obligations if they are immaterial in the context of the contract with the customer.

The Company’s subscription revenue as further discussed below is recognized ratably over the subscription period, which is 12 months.

Nature of Products and Services

The Company generates revenues from the following sources: (1) Benchtop Laboratory Equipment Operations and (2) Bioprocessing Systems Operations.

Benchtop Laboratory Equipment Operations' revenues are comprised primarily of benchtop weighing and measurement equipment sold to distributors, or to end users primarily via e-commerce. The sales cycle from time of receipt of order to shipment is very, short varying from a day to a few weeks. Customers either pay by credit card (e-commerce sales) or Net 30-60, depending on the customer. Revenue is recognized at the point in time when the item is shipped. Once the item is shipped under the FOB terms specified in the order, which is primarily “FOB Factory”, other than a standard warranty, there are no other obligations to the customer. Warranty usually consists of one year parts and labor and is deemed immaterial.  In addition, the Company recently introduced subscription plans, exclusively to the Benchtop Laboratory Equipment Operations' VIVID ONE/WORKSTATION customers, providing them with access to certain cloud-based information through payment of an annual subscription fee. The Company recognized revenue related to these subscriptions amounting to $115,100 and $67,000 for the years ended December 31, 2025 and 2024, respectively.

Bioprocessing Systems Operations revenues are comprised primarily of bioprocessing products, principally products incorporating smart sensors and state of the art software analytics. Products offered for sale include the Cell Growth Quantifier (“CGQ”) for Biomass monitoring in shake flasks, the Liquid Injection System (“LIS”) for automated feeding in shake flasks, and a line of coaster systems and flow-through cells for pH and DO monitoring. Revenue is recognized at the point in time when the item is shipped.

Segment Reporting

The Company views its operations as two operating segments, that are also the two reporting segments: the manufacture and marketing of benchtop laboratory equipment sold primarily through distributors consisting of balances, scales, moisture analyzers, force gauges, pill counters (“Benchtop Laboratory Equipment Operations”), and the manufacture, design, and marketing of bioprocessing systems and products (“Bioprocessing Systems Operations”).

The Company’s chief operating decision maker (“CODM”) regularly reviews revenue and operating income/loss for each segment in determination of allocating resources and assessing financial performance results for each operating segment. In their combined capacity as a group of top executives, the Company’s President and Chief Executive Officer and the Chief Executive Officer and President of the Bioprocessing Systems Operations, have been identified as the Company’s CODM. Significant segment expenses regularly provided to the CODM relate to employee compensation expenses which are included within the reported measure(s) of the Company’s segments profit or loss.

The Company eliminates inter-segment activity in the Company’s reporting segment results to be consistent with the information that is presented to the CODM, in accordance to ASC 280-10-580-28A. The Company also included a Non-operating Corporate segment in the Company’s reporting segment results.

Cash and Cash Equivalents

The Company considers all highly liquid instruments purchased with original maturities of 90 days or less to be cash equivalents. At times, cash balances may be in excess of the Federal Deposit Insurance Corporation (“FDIC”) insurance limit. As of December 31, 2025 and 2024, $90,400 and $0, respectively, of cash balances were in excess of the FDIC limit.

Allowance for Credit Losses - Accounts Receivable

The allowance for credit losses required under ASC 326 is a valuation account that is deducted from the accounts receivables’ cost basis on the Company’s consolidated balance sheets. The Company’s accounts receivables are generated from the sales revenue derived from the Company’s Benchtop Laboratory Equipment and Bioprocessing Systems segments. The Company elected to estimate expected losses using an analytical model based on methods that utilize the accounts receivable aging schedule. This analytical model incorporates historical loss activity, geographic location, customer-specific information, collection terms and customer amounts. The Company evaluates the estimated allowance on an aggregate basis as each individual account receivable shares similar risk characteristics.

The allowance for credit losses as of December 31, 2025 and 2024 was $8,300 and $15,600, respectively.

Investment Securities

The Company’s investment securities are classified as mutual funds and recorded at fair value. Changes in fair value of mutual funds are recorded as net unrealized gains or losses in other income (loss), net on the consolidated statement of operations and comprehensive loss.

The Company determines the cost of the investment sold based on an average cost basis at the individual security level and records the interest income and realized gains or losses on the sale of these investments in other income, net on the consolidated statement of operations and comprehensive loss.

Inventories

Current and noncurrent inventories recorded other than those of Aquila, are valued at the lower of cost (determined on a first-in, first-out basis) or net realizable value, and have been reduced by an allowance for excess and obsolete inventories. Inventories of Aquila are valued at the lower of cost (determined on a average cost method) or net realizable value, and have been reduced by an allowance for excess and obsolete inventories. The Company’s inventory allowance is based on management’s estimates and reviews of inventories on hand compared to estimated future usage and sales. Cost of work-in-process and finished goods inventories include material, labor and manufacturing overhead. As needed, the Company may purchase critical raw materials that are used in the core production process in quantities that exceed anticipated consumption within the normal operating cycle, which is 12 months. The Company classifies such raw materials that the Company does not expect to consume within the normal operating cycle as noncurrent.

Property and Equipment

Property and equipment are stated at cost. Depreciation of property and equipment is provided for primarily by the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized by the straight-line method over the remaining term of the related lease or the estimated useful lives of the assets, whichever is shorter.

Goodwill and Finite Lived Intangible Assets and Long-Lived Assets, Net 

Goodwill represents the excess of purchase price over the fair value of identifiable net assets acquired in a business combination. Goodwill and long-lived intangible assets are tested for impairment at least annually in accordance with the provisions of ASC No. 350, “Intangibles- Goodwill and Other” (“ASC No. 350”). ASC No. 350 requires that goodwill be tested for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. Application of the goodwill impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units, and determination of the fair value of each reporting unit.

As of December 31, 2025, the Company had two reporting units, the Benchtop Laboratory Equipment Operations and the Bioprocessing Systems Operations. Goodwill is tested for impairment by reporting unit on an annual basis as of December 31, the last day of its fiscal year, and in the interim if events and circumstances indicate that goodwill may be impaired. The events and circumstances that are considered in the Company’s goodwill impairment testing include business climate and market conditions, legal factors, operating performance indicators and competition. Impairment of goodwill is first assessed using a qualitative approach. If the qualitative assessment suggests that impairment is more likely than not, a quantitative analysis is performed. The quantitative analysis involves a comparison of the fair value of the reporting unit with its carrying amount. The fair value is determined using the income approach, which utilizes the present value of expected future cash flows for each reporting unit based on estimate future cash flows, the timing of these cash flows, and a discount rate based on a weighted average cost of capital. The assumptions used to estimate future cash flows and the development of forecasts used in the fair value determination were based on assumptions made using the best information available at the time, subject to inherent risk and judgement. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. To the extent additional information arises, market conditions change, or our strategies change, it is possible that the conclusion regarding whether our remaining goodwill is impaired could change and result in future goodwill impairment charges that will have a material effect on our consolidated financial position or results of operations.

During the year ended December 31, 2025, the Company elected to perform the qualitative analysis for the Benchtop Laboratory Equipment Operation reporting unit. This qualitative analysis evaluated factors, including, but not limited to, economic, market and industry conditions, cost factors and the overall financial performance of the reporting unit. In completing these assessments, the Company noted no changes in events or circumstances that indicated that it was more likely than not that the fair value of the reporting unit was less than its carrying amount.

As of December 31, 2025 and 2024 there was no remaining goodwill to the Bioprocessing System Operations reporting unit.

Intangible assets consist primarily of acquired technology, customer relationships, non-compete agreements, patents, licenses, websites, intellectual property in-process research and development (“IPR&D”), trademarks and trade names. All intangible assets are amortized on a straight-line basis over the estimated useful lives of the respective assets, generally 3 to 10 years. The Company continually evaluates the remaining estimated useful lives of intangible assets that are being amortized to determine whether events or circumstances warrant a revision to the remaining period of amortization. The Company reviews the recoverability of our finite-lived intangible assets and long-lived assets, when events or conditions occur that indicate a possible impairment exists. Determining whether impairment has occurred typically requires various estimates and assumptions, including determining which cash flows are directly related to the potentially impaired asset, the useful life over which cash flows will occur, their amount and the asset’s residual value, if any. The assessment for recoverability is based primarily on our ability to recover the carrying value of its long-lived and finite-lived intangible assets from expected future undiscounted net cash flows. If the total of expected future undiscounted net cash flows is less than the total carrying value of the assets the asset is deemed not to be recoverable and possibly impaired. We then estimate the fair value of the asset to determine whether an impairment loss should be recognized. An impairment loss will be recognized if the asset’s fair value is determined to be less than its carrying value. Fair value is determined by computing the expected future discounted cash flows.

Impairment of Long-Lived Assets

The Company follows the provisions of ASC No. 360-10, “Property, Plant and Equipment - Impairment or Disposal of Long-Lived Assets (“ASC No. 360-10”). ASC No. 360-10 which requires evaluation of the need for an impairment charge relating to long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If an evaluation for impairment is required, the estimated future undiscounted cash flows associated with the asset would be compared to the asset’s carrying amount to determine if a write down to a new depreciable basis is required. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount that the carrying amount of the assets exceeds the fair value of the assets. The Company concluded that as of December 31, 2025, an impairment loss of $291,000 was required against long-lived intangible by the Company's Bioprocessing Systems Operations reporting unit as of December 31, 2025.  There was no impairment recorded by the Company as of December 31, 2024.

Leases

The Company accounts for its leases under ASC 842, “Leases”. The Company determines whether an agreement contains a lease at inception based on the Company’s right to obtain substantially all of the economic benefits from the use of the identified asset and its right to direct the use of the identified asset. Lease liabilities represent the present value of future lease payments and the Right-Of-Use (“ROU”) assets represent the Company’s right to use the underlying assets for the respective lease terms. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of the lease payments over the lease term. The ROU asset is further adjusted to account for previously recorded lease expenses such as deferred rent and other lease liabilities. As the Company’s leases do not provide an implicit rate, the Company used its incremental borrowing rate as the discount rate to calculate the present value of future lease payments, which was the interest rate that its bank would charge for a similar loan.

The Company elected not to recognize a ROU asset and a lease liability for leases with an initial term of twelve months or less. In addition to minimum lease payments, certain leases require payment of a proportionate share of real estate taxes and certain building operating expenses or payments based on an excess of a specified base. These variable lease costs are not included in the measurement of the ROU asset or lease liability due to unpredictability of the payment amount and are recorded as lease expenses in the period incurred. The Company’s lease agreements do not contain residual value guarantees.

The Company elected available practical expedients for existing or expired contracts of lessees wherein the Company is not required to reassess whether such contracts contain leases, the lease classification or the initial direct costs.

Advertising

Advertising costs are expensed as incurred. Advertising expense amounted to $278,000 and $324,600 for the years ended December 31, 2025 and 2024, respectively.

Research and Development

Research and development costs consisting of expenses for activities that are useful in developing and testing new products, as well as expenses that may significantly improve existing products, are expensed as incurred.

Stock Compensation Plan

Stock-based compensation is accounted for in accordance with ASC No. 718 “Compensation-Stock Compensation” (“ASC No. 718”) which requires compensation costs related to stock-based payment transactions to be recognized. With limited exceptions, the amount of compensation cost is measured based on the grant-date fair value of the equity or liability instruments issued. In addition, liability awards are measured at each reporting period. Compensation costs are recognized over the period that an employee provides service in exchange for the award.

The Company estimates the fair value of each stock-based grant using the Black-Scholes option pricing model. This model derives the fair value of stock options based on certain assumptions related to expected stock price volatility, expected option life, risk-free interest rate and dividend yield. The expected volatility is based on the historical volatility of the Company's stock price over the most recent period commensurate with the expected term of the stock option award. The estimate expected term is based on management’s analysis of historical exercise activity. The risk-free interest rate is based on published U.S. Treasury rates for a term commensurate with the expected term. The dividend yield is estimated as zero as the Company has not paid dividends in the past and does not have any plans to pay any dividends in the foreseeable future. The Company has elected to account for forfeitures only when they occur.

Foreign currency translation and transactions

The Company has determined that the functional currency and reporting currency for its Aquila operations in Germany is the Euro and the U.S. Dollar, respectively. All assets and liabilities of Aquila are translated at the current exchange rate as of the end of the reporting period, and revenue and expenses are translated at average exchange rates in effect during the period with the resulting gain or loss reflected as a foreign currency cumulative translation adjustment and reported as a component of accumulated other comprehensive income (loss). Gains and losses arising from currency exchange rate fluctuations on transactions denominated in a currency other than the local functional currency are included in other income.

Income taxes

The Company and its subsidiaries file a consolidated U.S. federal income tax return, and a tax return in Germany for Aquila. Income taxes are accounted for under the asset and liability method. The Company provides for federal, and state income taxes currently payable, as well as for those deferred due to timing differences between reporting income and expenses for financial statement purposes versus tax purposes. Deferred tax assets and liabilities are recognized for the future tax consequences attributed to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted income 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 of a change in income tax rates is recognized as income or expense in the period that includes the enactment date.

ASC 740 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. As of December 31, 2025 and 2024, respectively, the Company did not have any unrecognized tax benefits related to various federal and state income tax matters.

The Company recognizes interest and penalties on any unrecognized tax benefits as a component of income tax expense. The Company does not have any accrued interest or penalties associated with any unrecognized tax benefits. The Company is subject to U.S. federal income tax, as well as various state jurisdictions. The Company is currently open to audit under the statute of limitations by the federal and state jurisdictions for the fiscal years ended June 30, 2022 and after. The Company is currently open to audit under the statute of limitations by German tax authorities for the years ended December 31, 2020 and thereafter. The Company does not anticipate any material amount of unrecognized tax benefits within the next 12 months.

Earnings (Loss) Per Common Share

Basic earnings or loss per common share is computed by dividing net income (loss) by the weighted-average number of shares outstanding. Diluted earnings or loss per common share includes the dilutive effect of stock options and warrants, if any. The Company was in a net loss position for the years ended December 31, 2025 and 2024, respectively, therefore the basic loss per share is the same as dilutive loss per share as the inclusion of the weighted-average number of all potential dilutive common shares which consists of stock options and warrants are anti-dilutive. 

Reclassification

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

Recent Accounting Pronouncements not yet adopted

In July 2025, the FASB issued ASU 2025-05, “Financial Instruments - Credit Losses (Topic 326): Measurements of Credit Losses for Accounts Receivable and Contract Assets”, which provides a practical expedient related to the estimation of expected credit losses for current accounts receivable and current contract assets that arise from transactions accounted for under ASC 606, “Revenue from Contracts with Customers”. Under ASU 2025-05, an entity is required to disclose whether it has elected to use the practical expedient. An entity that makes the accounting policy election is required to disclose the date through which subsequent cash collection are evaluated.  The ASU is effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. The Company is currently evaluating ASU 2025-05 to determine the impact it may have on its consolidated financial statements.

In December 2025, the FASB issued ASU 2025-11, “Interim Reporting (Topic 270)”, which is intended to improve the navigability of the guidance in ASC 270, “Interim Reporting”, and clarify when it applies. Under the amendments, an entity is subject to ASC 270 if it provides interim financial statements and notes in accordance with U.S. GAAP. ASU 2025-11 also addresses the form and content of such financial statements, interim disclosures requirements, and establishes a principle under which an entity must disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027. The Company is currently evaluating ASU 2025-11 to determine the impact it may have on its consolidated financial statements.

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” and in January 2025, the FASB issued ASU No. 2025-01, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date”, which clarified the effective date of ASU 2024-04. The ASU requires, among other things, more detailed disclosures about types of expenses in commonly presented expense captions such as cost of sales and selling, general and administrative expenses and is intended to improve the disclosures about an entity's expenses including purchases of inventory, employee compensation, depreciation and intangible asset amortization. ASU 2024-03 will also require the Company to disclose both the amount and the Company's definition of selling expenses. The guidance, as clarified by ASU 2025-01, is effective for fiscal years beginning after December 15, 2026, and interim periods for fiscal years beginning after December 15, 2027, on a prospective or retrospective basis. Early adoption is permitted. We are currently evaluating the impact of adopting this ASU on our disclosures.

There are no other recent accounting pronouncements issued but not yet adopted that would have a material effect on our consolidated financial statements.
