Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of Interlink Electronics, Inc. (the Company) as of December 31, 2023 and 2022, and the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity, and cash flows for the years then ended, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America. Basis for Opinion These financial statements are the responsibility of the entity’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matters Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters. /s/ LMHS, P.C. We have served as the Company’s auditor since 2022.

March 2024 Common Stock Dividend On March 1, 2024, the Board of Directors declared a 50 % common stock dividend with a record date of March 11, 2024, that was paid on March 22, 2024. Settlement of fractional share interests will be made by issuing one full share of common stock in lieu of a fractional share. Although the exact effect on common stock outstanding will depend on the number of fractional share settlements, the stock dividend is expected to increase the number of issued and outstanding shares of common stock from 6,573,570 to approximately 9,860,355 . Except as otherwise noted, all references to common stock, common stock issuable upon conversion of preferred stock, and corresponding per share information throughout this Annual Report on Form 10-K have been retroactively adjusted to reflect the stock dividend, which is accounted for as a stock split effected in the form of a stock dividend. Fiscal Year Our fiscal year is the calendar year reporting cycle beginning January 1 and ending December 31. Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Our reporting currency is the United States dollar. Our consolidated financial statements include the accounts of Interlink Electronics, Inc. and our subsidiaries in China, Hong Kong, Singapore, and the United Kingdom. All intercompany accounts and transactions were eliminated in consolidation. Foreign Currency Translation The functional currency of our Chinese subsidiary is the Chinese Yuan Renminbi. The functional currency for our Hong Kong, Singapore and United Kingdom subsidiaries is the United States dollar. However, our Hong Kong, Singapore, and United Kingdom subsidiaries also transact business in their local currency. Assets and liabilities are translated into United States dollars at the exchange rate in effect on the balance sheet date. Revenues and expenses are translated at the average exchange rate prevailing during the respective periods. Foreign currency transaction and remeasurement gains and losses are included in results of operations within other 47 Table of Contents income (expense), net, for which gains of $ 3,000 and $ 121,000 were recorded in the years ended December 31, 2023 and 2022, respectively. Segment Reporting We operate in one reportable segment: the manufacture and sale of force/touch - and gas/environmental-sensing technology solutions. Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and disclosures made in the accompanying notes to the consolidated financial statements. Management regularly evaluates estimates and assumptions related to revenue recognition, allowances for credit losses, inventory valuation reserves, warranty reserves, stock-based compensation, purchased intangible asset valuations and useful lives, asset retirement obligations, and deferred income tax asset valuation allowances. These estimates and assumptions are based on current facts, historical experience and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. The actual results we experience may differ materially and adversely from our original estimates. To the extent there are material differences between the estimates and the actual results, our future results of operations will be affected. Revenue Recognition The Company recognizes revenue in accordance with Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (“ASC 606”), when its customer obtains control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services. To determine revenue recognition for arrangements that are within the scope of ASC 606, we perform the following five steps; (i) identify the contract(s) 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; and (v) recognize revenue when (or as) we satisfy a performance obligation. The five-step model is applied to contracts when it is probable that we will collect the consideration we are entitled to in exchange for the goods or services transferred to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, we assess the goods or services promised within each contract and determine those that are performance obligations and assess whether each promised good or service is distinct. We then recognize revenue in the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Delivery occurs when goods are shipped and title and risk of loss transfer to the customer, in accordance with the terms specified in the arrangement with the customer. Revenue recognition is deferred until the earnings process is complete. We (i) input orders based upon receipt of a customer purchase order, (ii) confirm pricing through the customer purchase order record, (iii) validate creditworthiness through past payment history, credit agency reports and other financial data, and (iv) recognize revenue upon shipment of goods or when risk of loss and title transfer to the buyer. All customers have warranty rights, and some customers also have explicit or implicit rights of return. We establish reserves for potential customer returns or warranty repairs based on historical experience and other factors that enable us to reasonably estimate the obligation. A portion of our product sales is made through distributors under agreements allowing for right of return. Our past history with these sell-through right of return provisions allow us to reasonably estimate the amount of inventory that could be returned pursuant to these agreements, and revenue is recognized accordingly. Warranty We establish reserves for future product warranty costs that are expected to be incurred pursuant to specific warranty provisions with our customers. We generally warrant our products against defects for one year from date of shipment, with certain exceptions in which the warranty period can extend to more than one year based on contractual agreements. Warranty claims charges are recorded within cost of revenue as claims are incurred and honored. At each reporting period, we adjust our reserve for warranty claims (as either a charge or benefit to cost of revenue) based on our actual warranty claims experience as a percentage of net revenue during the preceding 24 months, as an estimation of the total future warranty claims expected to be incurred and honored for goods sold through 48 Table of Contents the end of the reporting period. We also consider the effect of known operations issues that may have an impact that differs from historical trends. Historically, our warranty returns have not been material. Shipping and Handling Fees and Costs Amounts billed to customers for shipping and handling fees are classified in revenue. Costs incurred for shipping and handling are classified in cost of revenue. Engineering, Research and Development Costs Engineering, research and development (“R&D”) costs are expensed when incurred. R&D expenses consist primarily of compensation expenses for employees engaged in research, design and development activities. R&D expenses also include depreciation and amortization, and overhead, including facilities expenses. Advertising and Marketing Costs All of the costs related to advertising and marketing our products are expensed as incurred or at the time the marketing takes place. Stock-based Compensation All stock-based payments to employees, including grants of employee stock options and employee stock purchase rights, are recognized in the financial statements based on their respective grant date (measurement date) fair values. We calculate the compensation cost of full-value awards such as restricted stock-based on the market value of the underlying stock at the date of the grant. We estimate the expected life of a stock award as the period of time that the award is expected to be outstanding. We are required to estimate the fair value of stock-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense ratably over the requisite service periods. We estimate the fair value of each option award as of the date of grant using the Black-Scholes option pricing model, which was developed for use in estimating the value of traded options that have no vesting restrictions and that are freely transferable. The Black-Scholes option pricing model considers, among other factors, the expected life of the award and the expected volatility of our stock price. Although the Black-Scholes option pricing model meets the accounting guidance requirements, the fair values generated by the Black-Scholes option pricing model may not be indicative of the actual fair values of our awards, as it does not consider other factors important to those stock-based payment awards, such as continued employment, periodic vesting requirements, and limited transferability. We have elected to recognize compensation expense for all stock-based awards on a straight-line basis over the requisite service period for the entire award. The amount of compensation expense recognized through the end of each reporting period is equal to the portion of the grant-date value of the awards that have vested, or for partially vested awards, the value of the portion of the award that is ultimately expected to vest for which the requisite services have been provided. The benefits of tax deductions in excess of recognized compensation cost are reported as a financing cash flow. Other Income (Expense), Net Other income (expense), net, consists of interest income, foreign currency exchange gains and losses, gains and losses on marketable securities, and other non-operating income and expenses. Income Taxes We account for income taxes under the asset and liability method, whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. We assess the likelihood that our deferred tax assets will be recovered from future taxable income and to the extent we believe that recovery is not determinable beyond a “more likely than not” standard, we establish a valuation allowance. To the extent we establish a valuation allowance or increase or decrease this allowance in a period, we include an expense or benefit within the tax provision in the statement of operations. We also utilize a “more likely than not” recognition threshold and measurement analysis for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. We recognize potential accrued interest and penalties related to unrecognized tax benefits within the consolidated statements of operations as income tax expense. 49 Table of Contents We operate within multiple tax jurisdictions and are subject to audit in these jurisdictions. Our foreign subsidiaries are subject to foreign income taxes on earnings in their respective jurisdictions. Earnings of our foreign subsidiaries are included in our U.S. federal income tax return as they are earned. Comprehensive Income (Loss) Comprehensive income (loss) includes all components of comprehensive income (loss), including net income (loss) and any changes in equity during the period from transactions and other events and circumstances generated by non-owner sources. Earnings Per Share Basic earnings per share is computed by dividing net income (loss) applicable to common stockholders (i.e., net income (loss) adjusted for preferred stock dividends declared or accumulated) by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income (loss) applicable to common stockholders by the weighted average number of diluted common shares, which includes common stock equivalents from, if applicable, and if dilutive, unexercised stock options, unvested restricted stock units, and shares issuable upon conversion of convertible preferred stock. Unexercised stock options and unvested restricted stock units are considered to be common stock equivalents if, using the treasury stock method, they are determined to be dilutive. Convertible preferred stock is considered to be common stock equivalents if, using the if-converted method, they are determined to be dilutive. Under the two-class method of determining earnings for each class of stock, we consider the dividend rights and participating rights in undistributed earnings for each class of stock. On March 1, 2024, the Board of Directors declared a 50 % common stock dividend that was paid on March 22, 2024. For all years presented, all share and per share data have been retroactively adjusted for the effect of the 50 % common stock dividend, which is accounted for as a stock split effected in the form of a stock dividend. Leases The Company accounts for its leases under ASC 842. Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases and are recorded on the consolidated balance sheet as both a right-of-use asset and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and the right-of-use asset is amortized over the lease term. For finance leases, interest on the lease liability and the amortization of the right-of-use asset results in front-loaded expense over the lease term. Variable lease expenses are recorded when incurred. In calculating the right-of-use and lease liability, the Company has elected to combine lease and non-lease components. The Company excludes short-term leases having initial term of 12 months or less from the new guidance as an accounting policy election and recognizes rent expense on a straight-line basis over the lease term. Risk and Uncertainties Our future results of operations involve a number of risks and uncertainties. Factors that could affect our business or future results and cause actual results to vary materially from historical results include, but are not limited to, the rapid change in our industry; problems with the performance, reliability or quality of our products; loss of customers; impacts of doing business internationally, including foreign currency fluctuations, changes in the trade policies of countries in which we or our customers do business, and political instability; potential shortages of the supplies we use to manufacture our products; disruptions in our manufacturing facilities; changes in environmental directives impacting our manufacturing process or product lines; the development of new proprietary technology and the enforcement of intellectual property rights by or against us; our ability to attract and retain qualified employees; and our ability to raise additional capital. Our operations and financial results may be adversely affected by outbreaks of viruses, widespread illness, infectious diseases, contagions and unforeseen epidemics (such as the COVID-19 coronavirus) in countries in which our products are manufactured and sold. We experienced delays in the receipt of certain goods and the supply of our products from international and domestic shipping origins as a result of the COVID-19 pandemic and more general global supply chain constraints in fiscal 2021, and to a lesser extent in 50 Table of Contents fiscal 2022 and 2023. Depending on the continued extent and duration of these and similar constraints and disruptions, our supply chain, results of operations (including sales) or future business may be materially and adversely impacted. These and other issues affecting our international suppliers or internationally manufactured merchandise could have a material adverse effect on our business, results of operations and financial condition. Cash, Cash Equivalents and Restricted Cash We invest excess cash in highly liquid interest-bearing instruments, including commercial paper or money market accounts. Investments with original maturity dates less than 90 days are classified as cash equivalents. Cash that is reserved for a specific purpose and therefore not available for immediate or general business use is classified as restricted cash. All of our cash, cash equivalents and restricted cash are held at major financial institutions in the United States, China, Hong Kong and Singapore. Our balances in each country were insured at the maximum limit determined by each country. In the U.S., we had approximately $ 94,000 and $ 8.4 million in excess of the Federal Deposit Insurance Corporation limit of $ 250,000 per depositor, per insured bank at December 31, 2023 and 2022, respectively. Approximately $ 1.1 million and $ 0.7 million held in banks in China at December 31, 2023 and 2022, respectively, was not insured. Approximately $ 132,000 and $ 168,000 held in banks in Singapore at December 31, 2023 and 2022, respectively, was not insured. Approximately $ 40,000 and $ 63,000 held in banks in Hong Kong at December 31, 2023 and 2022, respectively, was not insured. Approximately $ 1.1 million held in banks in the United Kingdom at December 31, 2023 was not insured. Accounts Receivable and Allowance for Credit Losses Accounts receivable are recorded at the invoice amount and presented net of the allowance for credit losses. Our receivables do not bear interest. We evaluate the collectability of accounts receivable at each balance sheet date using a combination of factors, such as specific customer historical experience and credit quality, overall historical data, age of the accounts receivable balances, and economic conditions that may affect a customer’s ability to pay. We include any accounts receivable balances that are determined to be uncollectible in the overall allowance for credit losses using the specific identification method. After all attempts to collect a receivable have failed, the receivable is written off against the allowance. Inventories Inventories are stated at the lower of cost or net realizable value (“NRV”). Inventory costs are determined using standard costs which approximate actual costs under the first-in, first-out method. Costs include the costs of purchased materials and outsourced assembly. NRV is the amount by which the estimated selling price of the product exceeds the sum of any additional costs expected to be incurred on the sale of such product in the ordinary course of business. We evaluate inventories for excess quantities and obsolescence. Our evaluation considers market and economic conditions; technology changes; new product introductions; and changes in strategic business direction. Estimates by their very nature include elements that are uncertain. In order to state the inventory at the lower of cost or NRV, we maintain reserves against individual stocking units Inventory reserves, once established, are not reversed until the related inventories have been sold or scrapped. If future demand or market conditions are less favorable than our projections, a write-down of inventory may be required, and would be reflected in cost of revenues sold in the period the revision is made. Property, Plant and Equipment, Net Property, plant and equipment are carried at cost less accumulated depreciation and amortization. Depreciation and amortization expense are calculated using the straight-line method over the assets’ remaining estimated useful lives, ranging from two to five years for machinery and equipment, including product tooling; and the shorter of the lease terms or estimated useful lives for leasehold improvements. When property, plant and equipment is retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the accounts. Gains and losses from retirements and asset disposals are recorded in selling, general and administrative expenses. Repairs and maintenance on our property, plant and equipment are expensed in the period incurred. We perform periodic reviews to evaluate the recoverability of property, plant and equipment and to determine whether facts and circumstances exist that would indicate that the carrying amounts of property, plant and equipment exceed their fair values. If facts and circumstances indicate that the carrying amount of property, plant and equipment might not be fully recoverable, projected undiscounted net cash flows associated with the related asset or group of assets over their estimated remaining useful lives are 51 Table of Contents compared against their respective carrying amounts. In the event that the projected undiscounted cash flows are not sufficient to recover the carrying value of the assets, the assets are written down to their estimated fair values. All long-lived assets to be disposed of are reported at the lower of carrying amount or fair market value, less expected selling costs. Intangible Assets, Net Our intangible assets consist primarily of patents and trademarks and are carried at cost less accumulated amortization. We evaluate our finite-lived assets for impairment whenever events or changes in circumstances indicate the carrying value of an intangible asset or asset group may not be recoverable. The carrying value of an intangible asset or asset group is not recoverable if the amount of undiscounted future cash flows the assets are expected to generate (including any net proceeds expected from the disposal of the asset) are less than its carrying value. When we identify that an impairment has occurred, we reduce the carrying value of the asset to its comparable market value (if available and appropriate) or to its estimated fair value based on a discounted cash flow approach. As of December 31, 2023, we have not recognized any impairment losses for our intangible assets. Goodwill Goodwill arises from business combinations and is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill acquired in a purchase business combination is determined to have an indefinite useful life and is not amortized but is tested for impairment at least annually or more frequently in events and circumstances exist that indicate that a goodwill impairment test should be performed. We have selected December 31 as the date to perform the annual impairment test. As of December 31, 2023, we have not recognized any impairment losses for our goodwill. Fair Value Measurements We determine fair value measurements based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, we follow the following fair value hierarchy that distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) our own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs): Level 1: Observable inputs such as quoted prices for identical assets or liabilities in active markets; Level 2: Other inputs observable directly or indirectly, such as quoted prices for similar assets or liabilities or market-corroborate inputs; and Level 3: Unobservable inputs for which there is little or no market data and which requires the owner of the assets or liabilities to develop its own assumptions about how market participants would price these assets or liabilities. Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of assets and liabilities and their placement within the fair value hierarchy. Recently Issued Accounting Pronouncements We reviewed all recently issued accounting pronouncements and concluded they are not applicable or not expected to be material to our financial statements. Subsequent Events The Company has evaluated subsequent events through March 25, 2024, being the date these consolidated financial statements were issued. ​ 52 Table of Contents Note 2 – Details of Certain Financial Statement Components The following tables provide details of selected balance sheet items: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ December 31, ​ 2023 2022 Inventories (in thousands) Raw materials $ 1,986 $ 1,635 Work-in-process ​ ​ 232 ​ ​ 192 Finished goods ​ ​ 258 ​ ​ 285 Total inventories $ 2,476 $ 2,112 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ December 31, ​ 2023 2022 Property, plant and equipment, net ​ (in thousands) Furniture, machinery and equipment ​ $ 2,009 ​ $ 1,688 Leasehold improvements ​ 412 ​ 417 ​ ​ 2,421 ​ 2,105 Less: accumulated depreciation ​ ( 2,108 ) ​ ( 1,921 ) Total property, plant and equipment, net ​ $ 313 ​ $ 184 ​ Depreciation expense totaled $ 200,000 and $ 193,000 in 2023 and 2022, respectively.

Realized and unrealized gains and losses are reported in earnings within “other income (expense), net”. The specific identification method is used to determine realized gains and losses on AFS securities. During the years ended December 31, 2023 and 2022, we purchased $ 0 and $ 6.027 million of marketable securities, respectively and we sold $ 0 and $ 8.476 million of marketable securities, respectively, for realized gains of $ 0 and $ 2.249 million, respectively. ​ Note 4 – Acquisition Acquisition of Assets of SPEC Sensors and KWJ Engineering On December 16, 2022, we acquired substantially all of the assets of SPEC Sensors, LLC (“SPEC”), and KWJ Engineering, Inc. (“KWJ”) (collectively, “SPEC/KWJ”), two designers and manufacturers of gas, air and environmental quality sensors that were under common ownership, pursuant to an Asset Purchase Agreement, dated as of December 16, 2022 (the “Asset Purchase Agreement”), by and among the Company, SPEC/KWJ, and the respective equity holders of SPEC and KWJ. The Asset Purchase Agreement contains customary representations, warranties and covenants, including non-competition covenants. Under the terms of the Asset Purchase Agreement, the purchase price for both companies’ assets was $ 2,000,000 plus the amount by which the combined companies’ net working capital at closing was more than $ 1,350,000 . At closing, the purchase price was preliminarily calculated as $ 2,269,000 , of which $ 1,519,000 was paid to SPEC/KWJ, and $ 750,000 was paid into escrow against purchase price adjustments and potential claims for breaches of representations and warranties by SPEC/KWJ or the equity holders. Subsequent to the closing, the parties reached an agreement pursuant to which (i) the purchase price was reduced to $ 2,102,313 resulting from the determination that the closing date net working capital was $ 166,687 lower than was preliminarily calculated, with such funds having been distributed back to the Company from the escrow account in May 2023, and (ii) the remaining funds in the escrow account were released to SPEC/KWJ in May 2023 without prejudice to the Company’s rights in respect of breaches of representations, warranties or covenants. 54 Table of Contents The following table summarizes the fair values of the assets acquired and liabilities assumed at the acquisition date, giving effect to the post-closing purchase price adjustment (in thousands). ​ ​ ​ ​ ​ ​ ​ ​ Cash $ 541 Accounts receivable ​ 306 Inventories ​ 952 Prepaid expenses and other current assets ​ 52 Property and equipment ​ ​ 50 Deposits ​ 16 Accounts payable and accrued liabilities ​ ( 415 ) Net identifiable tangible assets acquired ​ 1,502 Developed technology ​ 134 Customer relationships ​ ​ 96 Tradenames and trademarks ​ ​ 47 In-process research and development ​ ​ 29 Non-compete agreements ​ ​ 26 Order backlog ​ ​ 22 Goodwill ​ ​ 246 Net assets acquired $ 2,102 ​ The fair value of accounts receivable is equal to the $ 306,000 gross contractual amount, as we expect the entire balance to be collectible. The goodwill recognized is attributable primarily to expected synergies and the assembled workforces of SPEC/KWJ. The goodwill is expected to be deductible for income tax purposes. Acquisition of Calman Technology Limited On March 17, 2023, we acquired all of the outstanding shares in Calman Technology Limited (“Calman”), a Scotland-based designer and manufacturer of membrane keypads, graphic overlays and printed electronics, pursuant to a Share Purchase Agreement (the “Share Purchase Agreement”) by and among the Company’s wholly owned United Kingdom subsidiary, Interlink Electronics Limited, and the shareholders of Calman. The Share Purchase Agreement contains customary representations, warranties and covenants, including non-competition covenants on the part of the sellers, who continue to be employed by Calman. Under the terms of the Share Purchase Agreement, the purchase price was GB£ 4,127,000 (approximately $ 4,912,000 ), of which GB£ 3,627,000 (approximately $ 4,317,000 ) was paid at closing and the remaining GB£ 500,000 (approximately $ 595,000 ) was held back against potential claims for breaches of representations and warranties (subject to certain deductibles and caps) and was paid to the sellers in December 2023. The purchase price was subject to adjustment based on the extent, if any, to which Calman’s net working capital at closing was more or less than GB£ 600,000 (approximately $ 714,000 ), which resulted in additional purchase consideration of approximately GB£ 1,292,000 (approximately $ 1,538,000 ). The following table summarizes the fair values of the assets acquired and liabilities assumed at the acquisition date (in thousands). ​ ​ ​ ​ Cash $ 1,577 Accounts receivable ​ 656 Inventories ​ 622 Prepaid expenses and other current assets ​ 12 Property, plant, and equipment ​ 146 Right-of-use assets ​ 91 Accounts payable and accrued liabilities ​ ( 615 ) Lease liabilities ​ ( 91 ) Net identifiable tangible assets acquired ​ 2,398 Developed technology ​ 381 Tradenames and trademarks ​ 214 Customer relationships ​ 1,260 Non-compete agreements ​ 843 55 Table of Contents Deferred tax liabilities ​ ( 710 ) Goodwill ​ 2,064 Net assets acquired ​ $ 6,450 ​ After our September 30, 2023 financial statements were issued, the valuation report for the acquired intangible assets was completed. Based on the results of that valuation report, we have revised the preliminarily allocated GB£ 3,404,000 (approximately $ 4,052,000 ) of goodwill to be allocated as follows: GB£ 320,000 (approximately $ 381,000 ) developed technology, GB£ 180,000 (approximately $ 214,000 ) trademarks and tradenames, GB£ 1,059,000 (approximately $ 1,260,000 ) customer relationships, GB£ 708,000 (approximately $ 843,000 ) non-compete agreements, and GB£ 1,734,000 (approximately $ 2,064,000 ) goodwill, offset by GB£ 597,000 (approximately $ 710,000 ) deferred tax liabilities. In addition, the changes in these provisional amounts resulted in an increase in amortization expense and accumulated amortization of GB£ 266,000 (approximately $ 329,000 ) recorded in the three months ended December 31, 2023, of which GB£ 20,000 (approximately $ 25,000 ) relates to the three months ended March 31, 2023, GB£ 123,000 (approximately $ 155,000 ) relates to the three months ended June 30, 2023, and GB£ 123,000 (approximately $ 149,000 ) relates to the three months ended September 30, 2023. The fair value of accounts receivable is equal to the $ 656,000 gross contractual amount, as we expect the entire balance to be collectible. The goodwill recognized is attributable primarily to expected synergies and the assembled workforce of Calman. The goodwill is not expected to be deductible for income tax purposes. The following represents the pro forma consolidated statement of operations as if both SPEC/KWJ and Calman had been included in our consolidated results for the full fiscal years ended December 31, 2023 and 2022 (unaudited): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Pro Forma ​ Year Ended December 31, ​ ​ 2023 ​ 2022 ​ ​ (in thousands) Revenue ​ $ 14,705 ​ $ 14,708 Net income ​ $ 157 ​ $ 2,835 ​ ​ Note 5 – Series A Convertible Preferred Stock In October and November 2021, the Company sold to investors in a private placement exempt from registration under the Securities Act of 1933, as amended, an aggregate of 200,000 shares of its 8.0 % Series A Convertible Preferred Stock, par value $ 0.01 per share, at an offering price of $ 25.00 per share, for gross proceeds of $ 5.0 million. After payment of placement agent cash fees and expenses of the offering, the Company received net proceeds of approximately $ 4.6 million. Holders of the Series A Convertible Preferred Stock generally have no voting rights. Dividends on the Series A Convertible Preferred Stock accrue daily and are payable monthly in arrears on the 15th day of the calendar month, at the rate of 8.0 % per annum of its liquidation preference, which is the equivalent to $ 2.00 per annum per share. Each share of Series A Convertible Preferred Stock is convertible into shares of the Company’s common stock at a conversion price of $ 8.33 per common share, or 3.0 shares of common stock, as adjusted for the 50 % common stock dividend declared and paid in March 2024, at any time at the option of the holder, subject to certain customary adjustments. Holders of Series A Convertible Preferred Stock do not participate in common stock dividends, but such common stock dividends if and when declared would reduce the conversion price at which shares of Series A Convertible Preferred Stock would convert into common stock. The Company may elect to automatically convert some or all of the Series A Convertible Preferred Stock into shares of common stock at any time on or after April 22, 2022 if the closing price of the common stock equals or exceeds $ 10.00 ( 120 % of the initial conversion price) for at least 20 out of 30 consecutive trading days ending within five trading days prior to the notice of automatic conversion. The Company may redeem, at the Company’s option, the Series A Convertible Preferred Stock, in whole or in part, at a cash redemption price of $ 27.50 plus accrued and unpaid dividends beginning April 22, 2022 through October 21, 2023, at a cash redemption price of $ 28.125 plus accrued and unpaid dividends beginning October 22, 2023 through October 21, 2024, and, at a cash redemption price of $ 28.75 plus accrued and unpaid dividends beginning October 22, 2024. If the Company exercises the foregoing redemption right, holders of the Series A Convertible Preferred Stock will have the right to convert such shares into shares of common stock at the conversion price until the redemption date specified in the redemption notice delivered by the Company. 56 Table of Contents The Company entered into a registration rights agreement with the investors pursuant to which the Company agreed to register for resale by the investors the shares of common stock issuable upon conversion of the Series A Convertible Preferred Stock. The registration statement was filed on December 10, 2021, and was declared effective on December 21, 2021. ​ Note 6 – Stock-Based Compensation Under the terms of our 2016 Omnibus Incentive Plan, directors, officers and key employees could be granted restricted stock units and stock awards, as well as non-qualified or incentive stock options, at the discretion of the Compensation Committee of the Board of Directors. All stock-based payments to directors and employees, including grants of stock options and stock purchase rights, are recognized in the financial statements based on their respective grant date (measurement date) fair values. We calculate the compensation cost of full-value awards such as restricted stock units and stock awards based on the market value of the underlying stock at the date of the grant. The fair value of stock option awards is estimated at the date of grant using the Black-Scholes option pricing model; however, the value calculated using an option pricing model may not be indicative of the fair value observed in a willing buyer/willing seller market transaction, or actually realized by the employee upon exercise. Expected volatility used to estimate the fair value of options granted is based on the historical volatility of our common stock. The risk-free interest rate is based on the United States Treasury constant maturity rate for the expected life of the stock option. The expected life of a stock award is the period of time that the award is expected to be outstanding. We recognize compensation expense for all stock-based awards on a straight-line basis over the requisite service period for the entire award. The amount of compensation expense recognized through the end of each reporting period is equal to the portion of the grant-date value of the awards that have vested, or for partially vested awards, the value of the portion of the award that is ultimately expected to vest for which the requisite services have been provided. The benefits of tax deductions in excess of recognized compensation cost are reported as a financing cash flow. As of December 31, 2023, there were no stock-based compensation awards outstanding. The stock-based compensation expense recorded in the years ended December 31, 2023 and 2022 was for shares of common stock issued to members of the Board of Directors as partial compensation for their service as a director. ​ 57 Table of Contents Note 7 – Earnings Per Share Basic earnings per share is computed by dividing net income (loss) applicable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period, plus the dilutive effect of any dilutive securities. On March 1, 2024, the Board of Directors declared a 50 % common stock dividend with a record date of March 11, 2024, that was paid on March 22, 2024. The effect of this stock dividend (which is accounted for as a stock split effected in the form of a stock dividend) has been applied retroactively to weighted average common shares outstanding, earnings per share, and the conversion rate and conversion price applicable for our Series A Convertible Preferred Stock, as if the 50 % common stock dividend had occurred at the beginning of the earliest period presented. The following table sets forth the computation of basic and diluted earnings per share: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended ​ ​ December 31, ​ ​ 2023 ​ 2022 ​ ​ (in thousands, except per share data) Net income (loss) $ ( 383 ) $ 1,672 Less: Preferred stock dividends ​ ( 400 ) ​ ( 400 ) Net income (loss) applicable to common stockholders ​ $ ( 783 ) ​ $ 1,272 ​ ​ ​ ​ ​ ​ ​ Weighted average common shares outstanding – basic ​ 9,887 ​ 9,905 Dilutive potential common shares from convertible preferred stock ​ — ​ — Weighted average common shares outstanding – diluted ​ 9,887 ​ 9,905 ​ ​ ​ ​ ​ ​ ​ Earnings (loss) per common share, basic ​ $ ( 0.08 ) ​ $ 0.13 Earnings (loss) per common share, diluted ​ $ ( 0.08 ) ​ $ 0.13 ​ ​ ​ ​ ​ ​ ​ Shares subject to anti-dilutive Series A Convertible Preferred Stock excluded from calculation ​ 600 ​ 600 ​ 200,000 shares of Series A Convertible Preferred Stock convertible into 600,000 shares of common stock were outstanding but were not included in the computation of diluted earnings (loss) per share because the $ 8.33 conversion price was greater than the average market price of the common stock. ​ ​ Note 8 – Income Taxes Under GAAP, we use the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to 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 tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The components of earnings before income taxes for the years ended December 31, 2023 and 2022 were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended ​ ​ December 31, ​ 2023 2022 ​ ​ (in thousands) Income (loss) before income taxes: ​ ​ ​ ​ ​ ​ Domestic ​ $ ( 846 ) ​ $ 1,363 Foreign ​ 571 ​ 580 ​ ​ $ ( 275 ) ​ $ 1,943 ​ 58 Table of Contents Income tax provision consists of the following for the years ended December 31, 2023 and 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended ​ ​ December 31, ​ 2023 2022 ​ ​ (in thousands) Income tax provision (benefit): ​ ​ ​ ​ ​ ​ Current ​ ​ Federal ​ $ 27 ​ $ 254 State ​ 10 ​ 13 Foreign ​ 154 ​ 130 Total current ​ 191 ​ 397 Deferred: ​ ​ ​ ​ Federal ​ — ​ — State ​ — ​ — Foreign ​ ( 83 ) ​ ( 126 ) Total deferred ​ ( 83 ) ​ ( 126 ) Total income tax provision ​ $ 108 ​ $ 271 ​ A reconciliation of the income tax provision (benefit) by applying the statutory United States federal income tax rate to income (loss) before income taxes is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ ​ 2023 ​ 2022 ​ $ % $ % ​ ​ (in thousands, except percentages) Federal income tax provision (benefit) at statutory rate ​ $ ( 57 ) ​ 21.0 % $ 408 ​ 21.0 % State tax expense net of federal tax benefit ​ ( 54 ) ​ 19.6 % 130 ​ 6.7 ​ Foreign taxes ​ 23 ​ ( 8.4 ) % 22 ​ 1.1 ​ Other ​ 49 ​ ( 17.8 ) % ( 137 ) ​ ( 7.1 ) ​ Change in valuation allowance ​ 147 ​ ( 53.4 ) ​ ( 152 ) ​ ( 7.8 ) ​ Income tax provision ​ $ 108 ​ 39.3 % $ 271 ​ 13.9 % ​ Deferred tax assets and liabilities are recognized for future tax consequences between the carrying amounts of assets and liabilities and their respective tax basis using enacted tax rates in effect for the fiscal year in which the differences are expected to reverse. Significant deferred tax assets and liabilities, consist of the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ 2023 2022 ​ ​ (in thousands) Deferred taxes, net ​ ​ ​ ​ ​ ​ Net operating loss carryforward ​ $ 235 ​ $ 211 Accruals ​ 52 ​ 62 Reserves ​ 150 ​ 66 Property, plant and equipment, and intangible assets ​ 194 ​ 124 Stock-based compensation expense ​ 85 ​ 85 Other ​ 7 ​ 63 Total deferred tax assets ​ 723 ​ 611 Valuation allowance ​ ( 640 ) ​ ( 477 ) Net deferred tax assets ​ $ 83 ​ $ 134 ​ ​ ​ ​ ​ ​ ​ Intangible assets ​ ( 626 ) ​ — Net deferred tax liabilities ​ $ ( 626 ) ​ $ — ​ 59 Table of Contents Deferred taxes are recorded for the following net operating losses (“NOLs”) that can be used in future tax years: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ 2023 2022 ​ ​ (in millions) Net operating losses ​ ​ ​ ​ ​ ​ Federal ​ $ 0.5 ​ $ 0.6 State ​ 1.9 ​ 1.3 Foreign ​ — ​ — ​ ​ $ 2.4 ​ $ 1.9 ​ The federal and state NOLs expire at various dates between 2023 through 2030. Foreign NOLs are related to the jurisdiction of Hong Kong and may be carried forward indefinitely. The Company experienced an ownership change under IRC Section 382 in February 2010. In general, a Section 382 ownership change occurs if there is a cumulative change in our ownership by “5% shareholders” (as defined in the Internal Revenue Code of 1986, as amended) that exceeds 50 percentage points over a rolling three-year period. An ownership change generally affects the rate at which NOLs and potential other deferred tax assets are permitted to offset future taxable income. Certain state jurisdictions within which we operate contain similar provisions and limitations. As of December 31, 2022, $ 29.7 million of the federal NOLs and $ 13.7 million of the state NOLs are subject to annual limitations due to the February 2010 ownership change, at approximately $ 71,000 per year. Because these limitations preclude the use of a large portion of these NOLs, the Company permanently wrote-off the related deferred tax assets during the year ended December 31, 2015. Because the Company maintained a full valuation allowance against these deferred tax assets, this write-off had no impact on tax expense. At December 31, 2023, the gross NOLs without regard to this permanent write-off is $ 29.7 million for federal and $ 13.7 million for state. A roll-forward of the NOLs for which deferred tax assets are now recorded is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended ​ ​ December 31, ​ 2023 2022 ​ ​ (in millions) Net operating losses ​ ​ ​ ​ ​ ​ Balance at January 1, ​ $ 1.9 ​ $ 4.3 NOL generated (utilized) ​ 0.5 ​ ( 2.4 ) NOL expired unused ​ — ​ — Other, including changes in foreign exchange rates ​ — ​ — Balance at December 31, ​ $ 2.4 ​ $ 1.9 ​ Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize the existing deferred tax assets. We analyzed our need to record a valuation allowance against our otherwise recognizable net deferred tax assets in the federal, state and foreign jurisdictions, and we determined that a valuation allowance on federal and state deferred tax assets was necessary at both December 31, 2023 and 2022, while no valuation allowance on foreign deferred tax assets was necessary at both December 31, 2023 and 2022. One objective negative piece of evidence we evaluated was our cumulative domestic loss incurred over the three-year periods ended December 31, 2023 and 2022. Such objective negative evidence limits our ability to consider other subjective evidence, such as our projections for future profitability. On the basis of this evaluation, as of December 31, 2023 and 2022, a valuation allowance of $ 640,000 and $ 477,000 , respectively, was recorded against our domestic deferred tax assets. The amount of deferred tax assets considered realizable could be adjusted in future periods if estimates of future taxable income during the carryforward period are reduced or increased, or if objective negative evidence in the form of cumulative losses is no longer present and additional weight is given to subjective evidence such as our projections for future profitability. The Internal Revenue Code includes a provision, referred to as Global Intangible Low-Taxed Income (“GILTI”), which provides for a 10.5 % tax on certain income of controlled foreign corporations. We have elected to account for GILTI as a period cost if and when occurred, rather than recognizing deferred taxes for basis differences expected to reverse. Of our $ 4.3 million of cash at December 31, 2023, $ 2.3 million was held by our foreign subsidiaries. If these funds are needed for U.S. operations or for acquisitions, we have several methods to repatriate the funds without significant tax effects, including repayment of intercompany loans or distributions of previously taxed income. Other distributions may require us to incur U.S. or 60 Table of Contents foreign taxes to repatriate these funds. However, our intent is to permanently reinvest these funds outside the U.S. and our current plans do not demonstrate a need to repatriate cash. The Company is subject to taxation in the U.S. and various states and foreign jurisdictions. U.S. federal income tax returns after 2020 remain open to examination. We and our subsidiaries are also subject to income tax in multiple state and foreign jurisdictions. Generally, state and foreign income tax returns after 2019 remain open to examination. No income tax returns are currently under examination. As of December 31, 2023 and 2022, the Company does not have any unrecognized tax benefits, and continues to monitor its current and prior tax positions for any changes. The Company recognizes penalties and interest related to unrecognized tax benefits as income tax expense.

The leases expire at various dates through fiscal 2024 and frequently include renewal provisions for varying periods of time, provisions which require us to pay taxes, insurance and maintenance costs, and provisions for minimum rent increases. Minimum leases payments, including scheduled rent increases are recognized as rent expenses on a straight-line basis over the term of the lease. The rate implicit in each lease is not readily determinable, and we therefore use our incremental borrowing rate to determine the present value of the lease payments. The weighted average incremental borrowing rate used to determine the initial value of right-of-use (“ROU”) assets and lease liabilities capitalized during the years ended December 31, 2023 and 2022 was 5.50 % and 7.00 %, respectively. ROU assets for operating leases are periodically reduced by impairment losses. We use the long-lived assets impairment guidance in ASC Subtopic 360-10, Property, Plant and Equipment – Overall , to determine whether a ROU asset is impaired, and if so, the amount of the impairment loss to recognize. As of December 31, 2023, we have not recognized any impairment losses for our ROU assets. We monitor for events or changes in circumstances that require a reassessment of our leases. When a reassessment results in the remeasurement of a lease liability, a corresponding adjustment is made to the carrying amount of the corresponding ROU asset unless doing so would reduce the carrying amount of the ROU asset to an amount less than zero. In that case, the amount of the adjustment that would result in a negative ROU asset balance is recorded in profit or loss. In June 2023, we entered into a lease agreement to lease 1,560 square feet of office space in Irvine, California for approximately $ 4,000 per month for a term commencing June 2023 and ending May 2024. Our Irvine, California office is used for executive offices, sales, finance and administration. We previously occupied a different 4,351 square-foot office space in Irvine, California from June 2020 to May 2023 under a sublease agreement for approximately $ 6,000 per month, plus common area maintenance costs. We lease a 14,476 square-foot manufacturing facility and administrative office in Shenzhen, China. In May 2022, we renewed this lease for the period June 1, 2022 through May 31, 2024 for approximately $ 8,000 per month. We lease a 10,635 square-foot manufacturing facility and administrative offices in Newark, California. In February 2023, we renewed this lease for the period March 1, 2023 through February 28, 2024 for approximately $ 18,000 per month. In February 2024, we extended this lease for the period March 1, 2024 to February 28, 2025 for approximately $ 19,000 per month. We lease a 9,800 square-foot manufacturing facility and administrative offices in Irvine, Scotland for approximately $ 5,000 per month (with a 50 % discount through October 2023). This lease term ends February 2028, with an option for us to terminate the lease in February 2025. We lease a 275 square-foot engineering and administrative office in Singapore for approximately $ 1,000 per month. This lease term ends May 2024. We lease a 3,000 square-foot distribution facility in Hong Kong for approximately $ 2,000 per month. This lease term ends April 2025. We lease a 500 square-foot sales office in Tokyo, Japan for approximately $ 1,000 per month. This lease term ends November 2024. As of December 31, 2023, the Company had current and long-term lease liabilities of $ 126,000 and $ 33,000 , respectively, and ROU assets of $ 143,000 . As of December 31, 2022, the Company had current and long-term lease liabilities of $ 131,000 and $ 46,000 , respectively, and ROU assets of $ 172,000 . Future imputed interest as of December 31, 2023 totaled $ 7,000 . The weighted average remaining lease term of the Company’s leases as of December 31, 2023 is 0.7 years. 64 Table of Contents Future minimum lease payments under non-cancellable operating leases that have remaining non-cancellable lease terms in excess of one year are as follows: ​ ​ ​ ​ ​ Years ending December 31, (in thousands) 2024 ​ $ 133 2025 ​ 33 2026 ​ — 2027 ​ — 2028 ​ ​ — Thereafter ​ — Total undiscounted future non-cancelable minimum lease payments ​ 166 Less: imputed interest ​ ( 7 ) Present value of lease liabilities ​ $ 159 ​ During the year ended December 31, 2023, we incurred approximately $ 501,000 in operating lease costs, including approximately $ 211,000 in cost of revenue and approximately $ 290,000 in operating expenses. During the year ended December 31, 2022, we incurred approximately $ 255,000 in operating lease costs, including approximately $ 126,000 in cost of revenue and approximately $ 129,000 in operating expenses. Litigation We are not party to any material legal proceedings at December 31, 2023. We are occasionally involved in legal proceedings in the ordinary course of business, including actions against us which assert or may assert claims or seek to impose fines and penalties in substantial amounts. Related legal defense costs are expensed as incurred. Warranties We establish reserves for future product warranty costs that are expected to be incurred pursuant to specific warranty provisions with our customers. We generally warrant our products against defects for one year from date of shipment, with certain exceptions in which the warranty period can extend to more than one year based on contractual agreements. Our warranty reserves are established at the time of sale and are updated throughout the warranty period based upon numerous factors including historical warranty return rates and claim costs over various warranty periods. Historically, our warranty returns have not been material. Intellectual Property Indemnities We indemnify certain customers and our contract manufacturers against liability arising from third-party claims of intellectual property rights infringement related to our products. These indemnities appear in development and supply agreements with our customers as well as manufacturing service agreements with our contract manufacturers, are not limited in amount or duration and generally survive the expiration of the contract. Given that the amount of any potential liabilities related to such indemnities cannot be determined until an infringement claim has been made, we are unable to determine the maximum amount of losses that we could incur related to such indemnifications. 65 Table of Contents Director and Officer Indemnities and Contractual Guarantees Pursuant to our bylaws, we will indemnify our directors and executive officers to the fullest extent permitted by Nevada law, without limitation as to amount or duration, in the event of any actual or threatened lawsuit or proceeding. Certain costs incurred in connection with such indemnifications may be recovered under certain circumstances under various insurance policies. Given that the amount of any potential liabilities related to such indemnities cannot be determined until a lawsuit or proceeding has been threatened or filed, we are unable to determine the maximum amount of losses that we could incur relating to such indemnities. We have also entered into an employment agreement with Steven N. Bronson, our Chairman of the Board, President and Chief Executive Officer. This agreement contains certain severance and change in control obligations. Under the agreement, if Mr. Bronson’s employment is terminated due to his death or disability (as such terms are defined in the agreement), Mr. Bronson or his beneficiaries will be entitled to receive: (i) his base compensation to the end of the monthly pay period immediately following the date of termination; (ii) accrued bonus payments; and (iii) immediate and full vesting of all unvested equity and/or options issued by the Company. If Mr. Bronson’s employment is terminated by him for good reason (as such term is defined in the agreement), or by us without cause, then Mr. Bronson will be entitled to receive: (i) his base compensation to the date of termination; (ii) a severance payment equal to twelve months of his base compensation; (iii) any earned bonus compensation; (iv) employee benefits for twelve months following the date of termination; (v) any vested company match 401(k) or other retirement contribution; and (vi) immediate and full vesting of all unvested equity and/or options issued by the Company. In the event of a change in control of the Company (as such term is defined in the agreement), Mr. Bronson is entitled to receive: (i) a change in control payment in an amount equal to twelve months of his base compensation, payable as of the date the change in control occurs; and (ii) immediate and full vesting of all unvested equity and/or options issued by the Company. Guarantees and Indemnities In the normal course of business, we are occasionally required to undertake indemnification for which we may be required to make future payments under specific circumstances. We review our exposure under such obligations no less than annually, or more frequently as required. The amount of any potential liabilities related to such obligations cannot be accurately determined until a formal claim is filed. Historically, any such amounts that become payable have not had a material negative effect our business, financial condition or results of operations. We maintain general and product liability insurance which may provide a source of recovery to us in the event of an indemnification claim. ​ ​ 66 Table of Contents ITEM 9.
