ACORN ENERGY, INC.

NOTE 1—NATURE OF OPERATIONS

(a) Description of Business

Acorn Energy, Inc. and its subsidiaries, OMX Holdings, Inc. and OmniMetrix, LLC (collectively, “Acorn” or “the Company”) is a Delaware corporation which is a holding company focused on technology-driven solutions for energy infrastructure asset management. The Company provides the following products and Internet of Things (“IoT”) applications and services through its OmniMetrix, LLC (“OmniMetrix”) subsidiary:

Power Generation (“PG”). OmniMetrix’s PG services provide wireless remote monitoring and control systems and IoT applications for commercial/industrial and residential power generation equipment. In 2025, the Company launched the Omni family of products—the OmniPro commercial monitor and the Omni residential monitor—built on a new proprietary common communications core called the OCOM, a platform designed to enhance connectivity, reliability, and performance in remote monitoring systems. These products are replacing the Company’s legacy TrueGuard product lines, offering enhanced flexibility, expandability, and improved connectivity with easier installation. OmniMetrix also offers the Smart Annunciator product for commercial customers who require a visual representation of generator status via a touchscreen display.

Cathodic Protection (“CP”). OmniMetrix’s CP services provide remote monitoring and control products for cathodic protection systems on gas pipelines serving the gas utilities market and pipeline operators. The CP product lineup includes solutions to remotely monitor and control rectifiers, test stations and bonds. In 2025, the Company launched the RADex, an OCOM-based expansion of our RAD™ (Remote AC Mitigation Disconnect) that adds cathodic protection measurements while retaining the ability to remotely disconnect/connect AC mitigation tools on solid-state decouplers, reducing expense and increasing employee safety.

Acorn’s shares are traded on NASDAQ under the symbol ACFN.

(b) Liquidity

As of December 31, 2025, the Company had $4,454,000 of consolidated cash.

At December 31, 2025, the Company had working capital of $3,157,000. Its working capital includes $4,454,000 of cash and deferred revenue of $3,097,000. Such deferred revenue does not require a significant cash outlay for the revenue to be recognized. Total deferred revenue decreased by $824,000, from $4,233,000 at December 31, 2024 to $3,409,000 at December 31, 2025, as a result of the sales mix of products sold. Based on the current products being sold, the Company expects continued decreases in the deferred revenue balance in the foreseeable future. The balance of deferred hardware revenue at December 31, 2025 will continue to be amortized over the months remaining in the three-year period since the hardware’s original date of shipment. Net cash increased during the year ended December 31, 2025 by $2,128,000, with $2,090,000 provided by operating activities, $33,000 used in investing activities, and $71,000 provided by financing activities.

As of March 3, 2026, the Company had cash of $4,131,000 . The Company believes that such cash, plus the cash expected to be generated from operations, will provide sufficient liquidity to finance the corporate activities of Acorn and operating activities of OmniMetrix at their current level of operations for at least the twelve-month period from the issuance of these audited consolidated financial statements. The Company may, at some point, elect to obtain a new line of credit or other source of financing to fund additional investments in the business. If the Company decides to pursue additional financing in the future, it may be in the form of a bank line, a new loan or investment by others, an equity raise by Acorn which could then facilitate a loan by Acorn to OmniMetrix, or any combination thereof. Whether alternative funds, such as third-party loans or investments, will be available at the time and on terms acceptable to Acorn and OmniMetrix cannot be determined at this time.

NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). All dollar amounts are rounded to the nearest thousand and, thus, are approximate.

Principles of Consolidation and Presentation

The consolidated financial statements include the accounts of Acorn Energy, Inc. (“Acorn”) and its subsidiaries, OmniMetrix, LLC (“OmniMetrix”) and OMX Holdings, Inc. (collectively, with Acorn and OmniMetrix, “the Company”). Intercompany transactions and balances are eliminated in consolidation; profits from intercompany sales are also eliminated; and non-controlling interests are included in equity.

Use of Estimates in Preparation of Financial Statements

The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting periods.

As applicable to these consolidated financial statements, the most significant estimates and assumptions relate to uncertainties with respect to valuation allowance.

Accounts Receivable and Credit Losses

Accounts receivable consists of trade receivables. Trade receivables are recorded at the invoiced amount, net of any allowance for credit losses.

The Company’s trade receivables primarily arise from the sale of our products to a national telecommunications company, independent residential dealers, industrial distributors and dealers, national and regional retailers, equipment distributors, and certain end users with payment terms generally ranging from 30 to 60 days. Certain very large commercial customers have 90-day terms. The Company evaluates the credit risk of a customer when extending credit based on a combination of various financial and qualitative factors that may affect the customer’s ability to pay. These factors include the customer’s financial condition and past payment experience.

The Company maintains an allowance for credit losses, which represents an estimate of expected losses over the remaining contractual life of its receivables considering current market conditions and estimates for supportable forecasts when appropriate. The Company measures expected credit losses on its trade receivables on an entity-by-entity basis. The estimate of expected credit losses considers a historical loss experience rate that is adjusted for delinquency trends, collection experience, and/or economic risk where appropriate. Additionally, management develops a specific allowance for trade receivables known to have a high risk of expected future credit loss.

For the Company, contract assets are subject to review under ASC 326 however, no credit losses on contract assets were incurred.

Inventory

Inventories are comprised of components (raw materials) and finished goods, which are measured at the lower cost or net realizable value.

Raw materials inventory is generally comprised of radios, cables, antennas, and electrical components. Finished goods inventory consists of fully assembled systems ready for final shipment to the customer. Costs are determined at cost of acquisition on a weighted average basis and include all outside production and applicable shipping costs.

All inventories are periodically reviewed to identify slow-moving and obsolete inventory. Management conducts an assessment at the end of each reporting period of the Company’s inventory reserve and writes off any inventory items that are deemed obsolete.

All inventories are periodically reviewed to identify slow-moving and obsolete inventory. Management conducted an assessment and wrote-off inventory valued at $27,000 and $12,000 for the years ended December 31, 2025 and 2024, respectively.

Impairment of Long-Lived Assets

The Company reviews long-lived assets, such as property and equipment, intangible assets subject to amortization, and right-of-use assets on operating leases for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. These events or changes in circumstances include, but are not limited to, significant underperformance relative to historical or projected future operating results, significant changes in the manner of use of the acquired assets or the strategy for the overall business, and significant negative industry or economic trends. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the asset group to the estimated undiscounted cash flows over the estimated remaining useful life of the primary asset included in the asset group. If the asset group is not recoverable, the impairment loss is calculated as the excess of the carrying value over the fair value.

Non-Controlling Interests

The Financial Accounting Standards Board (“FASB”) requires that non-controlling interests be reported as a component of equity, changes in a parent’s ownership interest while the parent retains its controlling interest be accounted for as equity transactions, and upon a loss of control, retained ownership interest be re-measured at fair value, with any gain or loss recognized in earnings. The Company attributes the applicable percentage of income and losses to the non-controlling interests associated with OmniMetrix (see Note 3).

Property and Equipment

Property and equipment are presented at cost at the date of acquisition. Depreciation and amortization are calculated based on the straight-line method over the estimated useful lives of the depreciable assets, or in the case of leasehold improvements, the shorter of the lease term or the estimated useful life of the asset, a portion of which is allocated to cost of sales. Improvements are capitalized while repairs and maintenance are charged to operations as incurred.

Capitalization of Software

The Company capitalizes certain implementation costs incurred in a hosting arrangement that is a service contract to develop or obtain internal-use software. During the year ended December 31, 2024, the Company capitalized internal-use software costs totaling $17,000. There wereno such costs capitalized during the year ended December 31,2025.

Deferred Sales Commissions

The Company pays its employees sales commissions for sales of hardware and for first sales of monitoring services (not for renewals). In accordance with Topic 606, Revenue from Contracts with Customers, of the FASB Accounting Standards Codification (ASC 606”), the Company capitalizes as a contract asset the sales commissions on these sales. Commissions earned from the sales of the new hardware products will be recognized when the product is shipped. Commissions earned from the sales of monitoring services continue to be deferred and amortized over the period of service. Contract assets associated with monitoring services are amortized over the expected monitoring life, including renewals.

Leases

The Company determines if a contractual arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current operating lease liabilities, and noncurrent operating lease liabilities on the Company’s consolidated balance sheets. The Company evaluates and classifies leases as operating or finance leases for financial reporting purposes. The classification evaluation begins at the commencement date and the lease term used in the evaluation includes the non-cancellable period for which the Company has the right to use the underlying asset, together with renewal option periods when the exercise of the renewal option is reasonably certain and failure to exercise such option would result in an economic penalty. All of the Company’s real estate leases are classified as operating leases.

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 the lease. Operating lease ROU assets and liabilities are recognized at the commencement date of the lease based on the present value of the lease payments over the lease term. The lease payments included in the present value are fixed lease payments. As most of the Company’s leases do not provide an implicit rate, the Company estimates its collateralized incremental borrowing rate, based on information available at the commencement date, in determining the present value of lease payments. The Company applies the portfolio approach in applying discount rates to its classes of leases. The operating lease ROU assets include any payments made before the commencement date. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company does not currently have residual value guarantees or restrictive covenants in its leases.

The Company also made accounting policy elections by class of underlying asset to not apply the recognition requirements of the standard to leases with terms of 12 months or less and to not separate non-lease components from lease components. Consequently, each separate lease component and the non-lease components associated with that lease component will be accounted for as a single lease component for lease classification, recognition, and measurement purposes.

The lease obligation liability was $1,042,000 and $98,000 as of December 31, 2025 and December 31, 2024, respectively.

Treasury Stock

Shares of common stock repurchased are recorded at cost as treasury stock. When shares are reissued, the cost method is used for determining cost. In accordance with GAAP, the excess of the acquisition cost over the reissuance price of the treasury stock, if any, is charged to additional paid-in capital, limited to the amount previously credited to additional paid-in capital, if any. Any excess is charged to accumulated stockholders’ deficit.

Segment Reporting

Operating segments are defined as components of an enterprise for which separate financial information is available and that is evaluated on a regular basis by the chief operating decision-maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s operations are organized into two reportable segments: PG and CP. See Note 1,Nature of Operations, for the description of each of these segments. The Company’s organizational structure is based on factors that the CODM uses to evaluate, view and run the business operations, which include, but are not limited to, the customer base, market share, competitive landscape and technology. The CODM uses several metrics to evaluate the performance of the overall business, including number of connections, revenue and profit margin and uses these results to allocate resources to each of the segments.

Revenue Recognition

The Company’s revenue recognition policy is consistent with applicable revenue recognition guidance and interpretations. The core principle of ASC 606 is to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASC 606 defines a five-step process to achieve this core principle, which includes: (1) identifying contracts with customers, (2) identifying performance obligations within those contracts, (3) determining the transaction price, (4) allocating the transaction price to the performance obligation in the contract, which may include an estimate of variable consideration, and (5) recognizing revenue when or as each performance obligation is satisfied. The Company assesses whether payment terms are customary or extended in accordance with normal practice relative to the market in which the sale is occurring. The Company’s sales arrangements generally include standard payment terms. These terms effectively relate to all customers, products, and arrangements regardless of customer type, product mix or arrangement size. See Note 13, Revenue, for further discussion.

Revenue from sales of the hardware products that are distinct products are recorded when shipped (with the exception of the hardware products under a material contract with one customer for which revenue is recognized when the unit is accepted) while the revenue from sales of the hardware products (product versions sold prior to September 1, 2023) that were not separable from the Company’s monitoring services was deferred and amortized over the estimated unit life. Product revenues are recognized at the point in time when control of the product is transferred to the customer, which typically occurs upon shipment or delivery to the one customer under a material contract. To determine when control has transferred, the Company considers if there is a present right to payment and if legal title, physical possession, and the significant risks and rewards of ownership of the asset has transferred to the customer. Revenue from the prepayment of monitoring fees (generally paid twelve months in advance) are recorded as deferred revenue upon receipt of payment from the customer and then amortized to revenue over the monitoring service period. This method provides a faithful depiction of the transfer of services as it aligns the recognition of revenue with the period in which the monitoring services are provided. By deferring the revenue and recognizing it over the service period, the financial statements accurately reflect the company’s performance and obligations to its customers. See Notes 12 and 13 for the disaggregation of the Company’s revenue for the periods presented.

Any sales tax, value added tax, and other tax the Company collects concurrent with revenue producing activities are excluded from revenue.

Warranty Provision

OmniMetrix generally grants their customers a one-year warranty on their products; however, large volume contracts may receive a longer-term warranty. Estimated warranty obligations are provided for as a cost of sales in the period in which the related revenues are recognized, based on management’s estimate of future potential warranty obligations and historical experience. Adjustments are made to accruals as warranty claim data and historical experience warrant. The Company’s warranty obligations may be materially affected by product or service failure rates and other costs incurred in correcting a product or service failure. Should actual product or service failure rates or other related costs differ from the Company’s estimates, revisions to the accrued warranty liability would be required.

Concentration of Credit Risk

The Company’s financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash and trade accounts receivable. The Company’s cash was deposited with a U.S. bank and amounted to $4,454,000 at December 31, 2025. Although this balance exceeds the FDIC insurable limit, the Company does not believe there is a significant risk of non-performance by these counterparties. See Note 12(d) with respect to revenue from significant customers and concentrations of trade accounts receivable.

Financial Instruments

Fair values of financial instruments included in current assets and current liabilities are estimated to approximate their book values, due to the short maturity of such instruments.

Research and Development Expenses

Research and development expenses consist primarily of labor and related expenses and are charged to operations as incurred.

Advertising Expenses

Advertising expenses are charged to operations as incurred. Advertising expense was $9,000 and $18,000 for each of the years ended December 31, 2025 and 2024, respectively, and are included in selling, general and administrative expenses on the consolidated statements of operations.

Stock-Based Compensation

The Company accounts for stock-based awards to employees in accordance with applicable accounting principles, which requires compensation expense related to share-based transactions, including employee stock options, to be measured and recognized in the consolidated financial statements based on a determination of the fair value of the stock options. The grant date fair value is determined using the Black-Scholes-Merton (“Black-Scholes”) pricing model. For all employee stock options, the Company recognizes expense over the requisite service period on an accelerated basis over the employee’s requisite service period (generally the vesting period of the equity grant). Stock-based compensation expense is included in selling, general and administrative expenses. The Company’s option pricing model requires the input of assumptions, including the expected stock price volatility, expected term, and forfeiture rate. Any changes in these highly subjective assumptions significantly impact stock-based compensation expense.

Options awarded to purchase shares of common stock issued to non-employees in exchange for services are accounted for as variable awards in accordance with applicable accounting principles. Such options are valued using the Black-Scholes option pricing model when the services are performed.

See Note 9(a) for the assumptions used to calculate the fair value of stock-based employee compensation. Upon the exercise of options, it is the Company’s policy to issue new shares rather than utilizing treasury shares.

Sales Taxes

The Company accrues sales taxes based on determination of which of its products/services are subject to sales tax, and in which states and jurisdictions the tax applies. Further, the Company must determine which of its customers are exempt from the Company charging sales tax because the customer is a reseller or self-assesses and direct pays to states and other jurisdictions on purchases the customer makes from the Company. These determinations contain estimates and are subject to judgment and interpretation by taxing authorities in various states and other jurisdictions, which could result in recognizing materially different amounts in future periods. At December 31, 2025 and December 31, 2024, the amount of such accrual was $26,000 and $36,000, respectively.

Deferred Income Taxes

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, as well as operating loss, capital loss and tax credit carryforwards. Deferred tax assets and liabilities are classified as non-current. Valuation allowances are established against deferred tax assets if it is more likely than not that the assets will not be realized. Deferred tax assets and liabilities are measured using enacted 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 on deferred tax assets and liabilities of a change in tax rates or laws is recognized in operations in the period that includes the date of the enactment. See Note 10(d) for discussion around the impacts of the One Big Beautiful Bill of 2025.

As of December 31, 2024, the Company recorded a reduction in the valuation allowance of $4,686,000 that was previously recorded against our deferred tax assets. As of December 31, 2025, the Company recorded a reduction in the valuation allowance of $1,074,000 that was previously recorded against our deferred tax assets. The Company considered all the positive and negative evidence related to the likelihood of realization of the deferred tax assets and determined, based on the weight of available evidence, it is more likely than not that some of the deferred tax assets will be realized. As of December 31, 2025, we believe, based on our projections, that a partial valuation allowance of $10,326,000 is necessary against our deferred tax assets. Management will continue to assess the need for the valuation allowance and will make adjustments when appropriate. In forecasting future taxable income, management’s projections and beliefs are based upon a variety of estimates and numerous assumptions made by our management with respect to, among other things, interest rates, forecasted revenue of the hardware sales and monitoring revenue or revenue streams that could generate sufficient income so that the Company can utilize our net operating loss (NOL) carryforwards and other matters, many of which are difficult to predict, are subject to significant uncertainties and are beyond our control. As a result, there is inherently uncertainty that the estimates and assumptions upon which these projections and beliefs are based will prove to be accurate, that the anticipated results will be realized or that the actual results will not be substantially higher or lower than the Company projected.

Income Tax Uncertainties

The calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company recognizes liabilities for uncertain tax positions based on the two-step process prescribed by applicable accounting principles. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step requires the Company to estimate and measure the tax benefit as the largest amount that is more likely than not being realized upon ultimate settlement. It is inherently difficult and subjective to estimate such amounts, as this requires the Company to determine the probability of various possible outcomes. The Company reevaluates these uncertain tax positions on a quarterly basis. This evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit, and new audit activity. Such a change in recognition or measurement would result in the recognition of a tax benefit or an additional charge to the tax provision in the period. The Company recognizes interest and penalties as incurred in interest income, net in the consolidated statements of operations.

As of December 31, 2025 and 2024, no interest or penalties were accrued on the consolidated balance sheets related to uncertain tax positions.

During the years ending December 31, 2025 and 2024, the Company hadno changes in unrecognized tax benefits or associated interest and penalties as a result of tax positions made during the current or prior periods with respect to its continuing operations.

The Company is subject to U.S. Federal and state income tax. As of December 31, 2025, the Company is no longer subject to examination by U.S. Federal taxing authorities for years before 2022, or for years before 2021 for state income taxes.

Basic and Diluted Net Income Per Share

Basic net income per share is computed by dividing the net income attributable to Acorn Energy, Inc. by the weighted average number of shares outstanding during the year, excluding treasury stock. Diluted net income per share is computed by dividing the net income by the weighted average number of shares outstanding plus the dilutive potential of common shares which would result from the exercise of stock options and warrants. The dilutive effects of stock options and warrants are excluded from the computation of diluted net income per share if doing so would be antidilutive.

The combined weighted average number of options and warrants that were excluded from the computation of diluted net income per share, as they had an antidilutive effect, was 7,000 (which have a weighted average exercise price of $17.51) and 3,000 (which had a weighted average exercise price of $11.25) for the years ending December 31, 2025 and 2024, respectively.

The following data represents the amounts used in computing earnings per share and the effect on net income and the weighted average number of shares of dilutive potential common stock (in thousands):

Fair Value Measurement

The Company follows the provisions of the accounting standard which defines fair value, establishes a framework for measuring fair value and enhances fair value measurement disclosure. Under these provisions, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date.

The standard establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use on unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is described below:

Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

Level 2: Observable prices that are based on inputs not quoted on active markets but corroborated by market data.

Level 3: Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.

The carrying amounts for cash, accounts receivable, and accounts payable approximate their fair value because of their short-term maturity. The Company determined that the carrying amount of the lease liabilities approximate fair value since the applicable interest rate approximated fair value at the time the leases were entered into. While the Company believes the carrying value of the assets and liabilities are reasonable, considerable judgment is used to develop estimates of fair value; thus, the estimates are not necessarily indicative of the amounts that could be realized in a current market exchange.

Recent Accounting Pronouncements

In July 2025, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2025-05, which introduces a practical expedient and an accounting policy election for estimating expected credit losses on current accounts receivable and contract assets arising from revenue transactions under ASC Topic 606. The practical expedient allows entities to assume that current conditions as of the reporting date remain unchanged over the remaining life of the asset, thereby eliminating the need to incorporate forecasts of future economic conditions. The accounting policy election, available to entities other than public business entities, permits consideration of post-balance sheet cash collections in estimating expected credit losses, provided the practical expedient is also elected.

Although the Company qualifies as a public business entity and is therefore not eligible for the accounting policy election, the Company has evaluated the practical expedient and determined that it does not expect a material impact on its consolidated financial statements upon adoption.

ASU 2025-05 is effective for interim and annual periods beginning after December 15, 2025, with early adoption permitted. The Company does not plan to early adopt and will implement the guidance beginning with its first quarter of fiscal 2026.

In November 2024, the FASB issued Accounting Standards Update No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”), and in January 2025, the FASB issued Accounting Standards Update No. 2025-01, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date (“ASU 2025-01”). ASU 2024-03 requires additional disclosure of the nature of expenses included in the income statement as well as disclosures about specific types of expenses included in the expense captions presented in the income statement. ASU 2024-03, as clarified by ASU 2025-01, is effective for us for our annual reporting for fiscal 2027 and for interim period reporting beginning in fiscal 2028 on a prospective basis. Both early adoption and retrospective application are permitted. The Company is currently evaluating the impact that the adoption of these standards will have on its consolidated financial statements and disclosures.

Recently Adopted Accounting Standards

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disaggregated information about a reporting entity’s effective tax rate reconciliation, as well as information related to income taxes paid to enhance the transparency and decision usefulness of income tax disclosures. The Company adopted ASU 2023-09 for the current year and has elected to apply the standard on a prospective basis.

NOTE 3—INVESTMENT IN OMNIMETRIX

The Company owns 99% of the Company’s OMX Holdings, Inc. subsidiary (“Holdings”) and the former CEO of OmniMetrix, LLC owns the remaining 1%.

NOTE 4—ACCOUNTS RECEIVABLE AND ALLOWANCE FOR CREDIT LOSSES

The Company has historically experienced immaterial write-offs given the nature of the customers that receive credit. As of December 31, 2025, the Company had gross receivables of $892,000 and an allowance for credit losses of $5,000.

The following is a tabular reconciliation of the Company’s allowance for credit losses:

NOTE 5—INVENTORY

At December 31, 2025 and 2024, the Company’s inventory reserve for obsolescence was $6,000 for both periods.

NOTE 6—PROPERTY AND EQUIPMENT, NET

Property and equipment consists of the following:

During the year ended December 31, 2024, the Company wrote off fully depreciated equipment and software with an original cost of $294,000. These assets were no longer in use and had no remaining economic value. The write-off had no impact on the Company’s financial position or results of operations, as the assets were fully depreciated.

Depreciation and amortization in respect of property and equipment amounted to $115,000 and $121,000 for 2025 and 2024, respectively.

NOTE 7—LEASES

OmniMetrix leases office space and office equipment under operating lease agreements. The office lease, originally set to expire on September 30, 2025, was amended on June 20, 2025, to extend the lease term through November 30, 2030. The amendment also includes scheduled increases in monthly base rent and provides for conditional rent abatement for October and November 2025, as well as a tenant improvement allowance of up to $14,000 for qualifying alterations if completed by September 30, 2026. The Company concluded the amendment constitutes a modification event under ASC 842 and the Company reassessed and remeasured the lease. The Company remeasured the lease payments based on the updated lease term, incremental borrowing rate and adjusted the right of use asset and lease liability accordingly. The lease was determined to still represent an operating lease. The 6.0% discount rate used is the estimated incremental borrowing rate when the lease was entered into, which, as defined in ASC 842:Leases, is the rate of interest that a lessee would have had to pay to borrow, on a collateralized basis, over a similar term and in a similar economic environment, an amount equal to the lease payments. Operating lease cost, net of sublease, for the year ended December 31, 2025 and 2024 were $184,000 and $115,000, respectively.

Supplemental cash flow information related to leases consisted of the following (in thousands):

Supplemental balance sheet information related to leases consisted of the following:

The table below reconciles the undiscounted future minimum lease payments under non-cancelable lease agreements having initial terms of more than one year to the total operating lease liabilities recognized on the unaudited condensed consolidated balance sheet as of December 31, 2025 (in thousands):

On July 6, 2021, the Company entered into an agreement with King Industrial Realty, Inc. to sublease from the Company 1,900 square feet of the Company’s 21,000 square feet office and production space in the Hamilton Mill Business Park located in Buford, Georgia. This sublease was amended on August 15, 2025 to extend the term through September 30, 2028 and to provide a monthly sublease payment of $3,374 (plus an annual escalator each year of 4%) which includes the base rent plus a pro-rata share of utilities, property taxes and insurance. Fifty percent of any excess rent received above the per square foot amount that the Company pays will be remitted to the Company’s landlord less the allocation of any shared expenses and leasehold improvements specific to the sublease. For the year ended December 31, 2025, after the offset of the investment in leasehold improvements and other expenses related to the sublease, the total amount paid to our landlord under the sublease was $8,295.

Below are the future gross payments expected to be received by the Company under the sublease:

NOTE 8—COMMITMENTS AND CONTINGENCIES

The Company has $1,208,000 in operating lease obligations payable through 2030 and $217,000 in other contractual obligations. The contractual services include $202,000 payable through December 31, 2026 and $15,000 payable through December 31, 2027. The Company also has $434,000 in open purchase order commitments payable through September 30, 2026 of which $272,000 (63%) is to one electronics vendor.

NOTE 9—STOCKHOLDERS’ EQUITY (DEFICIT)

(a) Summary Employee Option Information

The Company’s stock option plans provide for the grant to officers, directors and employees of options to purchase shares of common stock. The purchase price may be paid in cash or, if the option is “in-the-money” at the end of the option term, it is automatically exercised “net.” In a net exercise of an option, the Company does not require a payment of the exercise price of the option from the option holder but reduces the number of shares of common stock issued upon the exercise of the option by the smallest number of whole shares that has an aggregate fair market value equal to or in excess of the aggregate exercise price for the option shares covered by the option exercised. Each option is exercisable for one share of the Company’s common stock. Most options expire within five to ten years from the date of the grant and generally vest over a three-year period from the date of the grant.

At December 31, 2025,63,235 options were available for grant under the Amended and Restated 2006 Stock Incentive Plan and no options were available for grant under the 2006 Stock Option Plan for Non-Employee Directors. In 2025,6,900 options were granted which were to directors and executive officers. In 2024,8,350 options were granted (6,900 to directors and executive officers and 1,450 to other employees). In 2025 and 2024, there were no grants to non-employees (other than the non-employee directors and executive officers). The fair value of the options issued was $119,000 and $53,000 in 2025 and 2024, respectively.

13,257 options were exercised in the year ended December 31, 2025.7,708 options were exercised in the year ended December 31, 2024. The intrinsic value of options outstanding and of options exercisable at December 31, 2025 was $476,000 and $457,000, respectively. The intrinsic value of options outstanding and of options exercisable at December 31, 2024 was $806,000 and $758,000, respectively.

The Company utilized the Black-Scholes option-pricing model to estimate fair value, utilizing the following assumptions for the respective years (all in weighted averages):

The expected term of the options is the length of time until the expected date of exercising the options. The Company estimated volatility by considering historical stock volatility over the expected term of the option. The risk-free interest rates are based on the U.S. Treasury yields for a period consistent with the expected term. The Company expects no dividends to be paid. The Company believes that the valuation technique and the approach utilized to develop the underlying assumptions are appropriate in determining the estimated fair value of the Company’s stock options granted in the years ended December 31, 2025 and 2024. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by persons who receive equity awards.

NOTE 10—INCOME TAXES

At each reporting period, the Company considered all the positive and negative evidence related to the likelihood of realization of the deferred tax assets and determined, based on the weight of available evidence, it is more likely than not that some of the deferred tax assets will be realized. As of December 31, 2025 and 2024 the Company recorded $15,513,000 and $15,933,000 of deferred tax assets before valuation allowance, respectively, which was offset by $10,326,000 and $11,400,000 of valuation allowance, respectively. The Company has recorded deferred tax liabilities of $288,000 and $98,000 as of December 31, 2025 and 2024, respectively, which have all been determined to be sources of future taxable income. The reduction of $1,074,000 of the valuation allowance is based on cumulative positive operating results over the prior three-year period and expectations about generating U.S. taxable income in the future. The remaining valuation allowance relates primarily to anticipated expirations of U.S. net operating losses prior to utilization based on our forecasts of future taxable income.

(b) Effective Income Tax Rates

Set forth below is a reconciliation between the federal tax rate and the Company’s effective income tax rates with respect to continuing operations:

Georgia

North Carolina

Pennsylvania

The rate reconciliation above has been adjusted to be presented in compliance with the guidance under ASU 2023-09. The Company has adopted this guidance on a prospective basis.

As previously disclosed for the year ended December 31, 2024, prior to the adoption of ASU No. 2023-09, the following reconciles the federal tax rate and the Company’s effective income tax rates with respect to continuing operations:

(c) Analysis of Deferred Tax Assets and (Liabilities) (in thousands):

Valuation allowances relate primarily to NOL carryforwards related to the Company’s consolidated tax losses as well as state tax losses related to the Company’s OmniMetrix subsidiary. During the years ended December 31, 2025 and 2024, the valuation allowance decreased by $1,074,000 and $4,686,000, respectively.

(d) Summary of Tax Loss Carryforwards

As of December 31, 2025, the Company had various NOL carryforwards expiring as follows (in thousands):

The utilization of the Company’s pre 2012 federal and state net operating losses may be subject to limitation under the Internal Revenue Code, as well as similar state provisions. Such limitations may result in the expiration of those net operating loss (NOL) carryforwards before their utilization. During 2025 the Company completed a Section 382 study and determined that no change of control occurred and the NOLs generated during the period of 2012 – 2024 will not be subject to limitation. Future changes in the Company’s stock ownership, which may be outside of the Company’s control may trigger an “ownership change” which could result in limitations under the Internal Revenue Code.

The Company maintains a valuation allowance against certain deferred tax assets where management has determined it is more-likely-than-not that such assets will not be realized. Any limitation under Section 382 may require the Company to increase its valuation allowance or could otherwise adversely impact the timing of tax benefits recognized in future periods.

On July 4, 2025, the One Big Beautiful Bill was enacted (“OBBBA”), introducing significant and wide-ranging changes to the U.S. federal tax system. Significant components include restoration of 100% accelerated tax depreciation on qualifying property including expansion to cover qualified production property. Another major aspect includes the return to immediate expensing of domestic research and experimental expenditures (“R&E”) which in some cases may include retroactive application back to 2021 for businesses with gross receipts of less than $31 million or accelerated tax deductions of R&E that was previously capitalized for larger businesses. The legislation also reinstates EBITDA-based interest deductions for tax purposes and makes several business tax incentives permanent. Less favorable business provisions include limitations on tax deductions for charitable contributions.

The Company is also subject to certain non-income taxes such as value added taxes, sales taxes, and property taxes. The Company has taken certain positions that management feels, although not free from doubt, should not result in a successful challenge by certain tax authorities.

NOTE 12—SEGMENT REPORTING AND GEOGRAPHIC INFORMATION

(a) General Information

As of December 31, 2025, the Company continues to operate intwo reportable operating segments, PG and CP, both of which are performed through the Company’s OmniMetrix subsidiary. See Note 1,Nature of Operations, for a description of these segments.

The Company’s reportable segments are strategic business units, offering different products and services and are managed separately by the CODM as each business requires different technology and marketing strategies.

The CODM is the Company’s Chief Executive Officer (CEO).

(b) Information about profit or loss and assets

The accounting policies of all the segments are those described in the summary of significant accounting policies. The Company evaluates performance by segment based on revenue (driven by the number of connections), gross profit and net income or loss before taxes.

The Company does not systematically allocate assets to the divisions of the subsidiaries constituting its consolidated group, unless the division constitutes a significant operation. Accordingly, where a division of a subsidiary constitutes a segment that does not meet the quantitative thresholds of applicable accounting principles, depreciation expense is recorded against the operations of such segment, without allocating the related depreciable assets to that segment. However, where a division of a subsidiary constitutes a segment that does meet the quantitative thresholds, related depreciable assets, along with other identifiable assets, are allocated to such division.

Segment expense that is routinely provided to the CODM is COGS and R&D expense. R&D expense is allocated to each segment based on estimated time on projects within the segment. SG&A expense and interest income is allocated to each segment based on the percentage of segment revenue to total revenue instead of being specifically identified to each segment since the Company’s resources have a high level of shared utilization between the segments. Further, the CODM does not review the assets by segment.

The following tables represent segmented data for the years ended December 31, 2025 and 2024 (in thousands).

(c) The following tables represent a reconciliation of the segment data to the consolidated statement of operations and balance sheet data for the years ended and as of December 31, 2025 and 2024 (in thousands):

NOTE 13—REVENUE

OmniMetrix sells monitoring equipment (“HW”) and monitoring services (“Monitoring”). Prior to September 1, 2023, sales of OmniMetrix equipment typically did not qualify as a separate unit of accounting. As a result, revenue (and related costs) associated with sale of equipment was recorded to deferred revenue (and deferred cost of goods sold) upon shipment of PG and CP monitoring units. Revenue and related costs with respect to the sale of equipment were recognized over the estimated life of the units which was estimated to be three years. On September 1, 2023, OmniMetrix launched an updated version of its products that includes new functionality in its TrueGuard, AIRGuard, Patriot and Hero products that allows its customers to have options as it relates to obtaining and utilizing the data that is provided by its hardware devices. This new functionality allows for SIM card options, configuration options regarding IP address endpoints and DNS routes, and access to OmniMetrix’s over-the-air data protocol. This product update allows customers to have the option to purchase OmniMetrix’s monitoring service, monitor the products themselves if they have the ability in-house, or choose another monitoring provider if they so desire. OmniMetrix’s prior hardware product version could not function as a distinct product independent from its monitoring services. This new version’s functionality results in OmniMetrix’s hardware and monitoring services being capable of being two distinct products and services. OmniMetrix recognizes revenue, COGS and commissions from the sale of the new version of its hardware products when the product is shipped rather than over the estimated time that the unit is in service for the customer. The remaining balance of deferred hardware revenue from the prior version of these products will continue to be amortized each period until it is fully amortized. The modifications to the circuit boards and embedded firmware of hardware enclosures in inventory as of August 31, 2023 were made such that only the new version of these products was sold subsequent to this date.
