NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

NOTE 1 - DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Data I/O Corporation (“Data I/O”, “We”, “Our”, “Us”) is a global market leader for advanced programming, security deployment, security provisioning and associated Intellectual Property (“IP”) protection and management solutions used in electronics manufacturing with flash memory, microcontrollers, and flash memory-based intelligent devices as well as secure element devices, authentication devices and secure microcontrollers. Customers for our programming system products are located around the world, primarily in Asia, Europe and the Americas. Our manufacturing operations are currently located in Redmond, Washington, United States and Shanghai, China.

We prepared the financial statements as of March 31, 2025 and March 31, 2024 according to the rules and regulations of the Securities and Exchange Commission ("SEC"). These statements are unaudited but, in the opinion of management, include all adjustments (consisting of normal recurring adjustments and accruals) necessary to present fairly the results for the periods presented. The balance sheet at December 31, 2024 has been derived from the audited financial statements at that date. We have condensed or omitted certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America according to such SEC rules and regulations. Operating results for the three months ended March 31, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025.

Significant Accounting Policies

These financial statements should be read in conjunction with the annual audited financial statements and the accompanying notes included in our Form 10-K for the year ended December 31, 2024 (filed with the SEC on April 1, 2025). There have been no changes to our significant accounting policies described in the Annual Report that have had a material impact on our unaudited condensed consolidated financial statements and related notes.

Revenue Recognition

Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers (ASC 606) provides a single, principles-based, five-step model to be applied to all contracts with customers. It generally provides for the recognition of revenue in an amount that reflects the consideration to which the Company expects to be entitled, net of allowances for estimated returns, discounts or sales incentives, as well as taxes collected from customers when control over the promised goods or services are transferred to the customer.

We expense contract acquisition costs, primarily sales commissions, for contracts with terms of one year or less and will capitalize and amortize incremental costs with terms that exceed one year. During the current and prior period quarters, the impact of capitalization of incremental costs for obtaining contracts were immaterial. We exclude sales, use, value added, some excise taxes and other similar taxes from the measurement of the transaction price.

We recognize revenue upon transfer of control of the promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We have determined that our programming equipment has reached a point of maturity and stability such that product acceptance can be assured by testing at the factory prior to shipment and that the installation meets the criteria to be a separate performance obligation. These systems are standard products with published product specifications and are configurable with standard options. The evidence that these systems could be deemed as accepted was based upon having standardized factory production of the units, results from batteries of tests of product performance to our published specifications, quality inspections and installation standardization, as well as past product operation validation with the customer and the history provided by our installed base of products upon which the current versions were based.

The revenue related to products requiring installation that is perfunctory is recognized upon transfer of control of the product to customers, which generally is at the time of shipment. Installation that is considered perfunctory includes any installation that is expected to be performed by other parties, such as distributors, other vendors, or the customers themselves. This analysis considers the complexity, skill and training needed and customer installation expectations.

Table of Contents

We enter into arrangements with multiple performance obligations that arise during the sale of a system that could include hardware, software, installation, services and support and extended maintenance components. We allocate the transaction price of each element based on the relative selling prices. Relative selling price is based on the selling price of the standalone system. For the installation and service and support performance obligations, we use the value of the discount given to distributors who perform these components. For software maintenance performance obligations, we use what we charge for annual software maintenance renewals after the initial year the system is sold. Revenue is recognized on the system based on shipping terms, software based on delivery, installation and services based on completion of work, and software maintenance and extended warranty support ratably over the term of the agreement, typically one year. Total deferred revenue which represents undelivered performance obligations for installation, service, support and extended contracts were $1.5 million and $1.8 million for March 31, 2025 and 2024, respectively, and the portion expected to be recognized within one year was $1.5 million and $1.6 million for March 31, 2025 and 2024, respectively.

When we license software separately, we recognize revenue upon the transfer of control of the software, which is generally upon shipment, provided that only inconsequential performance obligations remain on our part and substantive acceptance conditions, if any, have been met.

We recognize revenue when there is an approved contract that both parties are committed to perform, both parties’ rights have been identified, the contract has substance, collection of substantially all the consideration is probable, the transaction price has been determined and allocated over the performance obligations, the performance obligations including substantive acceptance conditions, if any, in the contract have been met, the obligation is not contingent on resale of the product, the buyer’s obligation would not be changed in the event of theft, physical destruction or damage to the product, the buyer acquiring the product for resale has economic substance apart from us and we do not have significant obligations for future performance to directly bring about the resale of the product by the buyer. We establish a reserve for sales returns based on historical trends in product returns and estimates for new items. Payment terms are generally 30 to 60 days from shipment.

We transfer certain products out of service from their internal use and make them available for sale. The products transferred are typically our standard products in one of the following areas: service loaners, rental or test units; engineering test units; or sales demonstration equipment. Once transferred, the equipment is sold by our regular sales channels as used equipment inventory. These product units often involve refurbishing and are sold in our normal and ordinary course of business with standard warranty coverage. The transfer amount is the product unit’s net book value, and the sale transaction is accounted for as revenue and cost of goods sold.

The following table represents our revenues by major categories:

	Three Months Ended
Net sales by type	March 31,<br><br>2025		Change			March 31,<br><br>2024
(in thousands)
Equipment	$	3,317		(1.5	%)	$	3,366

Software and Maintenance		896		1.0	%		887
Total	$	6,176		1.3	%	$	6,099

Share-Based Compensation

All stock-based compensation awards are measured based on estimated fair values on the date of grant and recognized as compensation expense on the straight-line method. Our share-based compensation is reduced for estimated forfeitures at the time of grant and revised as necessary in subsequent periods if actual forfeitures differ from those estimates.

Income Tax

Income taxes for U.S. and foreign subsidiary operations are computed at current enacted tax rates, less tax credits using the asset and liability method. Deferred taxes are adjusted both for items that do not have tax consequences and for the cumulative effect of any changes in tax rates from those previously used to determine deferred tax assets or liabilities. Tax provisions include amounts that are currently payable, changes in deferred tax assets and liabilities that arise because of temporary differences between the timing of when items of income and expense are recognized for financial reporting and income tax purposes, and any changes in the valuation allowance caused by a change in judgment about the realization of the related deferred tax assets. A valuation allowance is established when necessary to reduce deferred tax assets to amounts expected to be realized.

New Accounting Pronouncements – Standards Issued and Not Yet Implemented

In December 2023, the FASB issued ASU 2023-09 "Income Taxes (Topics 740): Improvements to Income Tax Disclosures" to expand the disclosure requirements for income taxes, specifically related to the rate reconciliation and income taxes paid. ASU 2023-09 is effective for our annual periods beginning January 1, 2025, with early adoption permitted. We are currently evaluating the potential effect that the updated standard will have on our financial statement disclosures.

In November 2024, FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation (Subtopic 220-40), which requires disclosure of specific information about costs and expenses within relevant expense captions on the face of the income statement, qualitative descriptions for expense captions not specifically disaggregated quantitatively, and the total amount and definition of selling expenses for interim and annual reporting periods. This standard is effective for the annual reporting period beginning January 1, 2027 and interim reporting periods beginning January 1, 2028 and should be applied retrospectively to all comparative periods. Early adoption is permitted. The Company is currently evaluating the effects of adopting this new accounting guidance.

NOTE 5– OPERATING LEASE COMMITMENTS

We have commitments under non-cancelable operating leases and other agreements, primarily for factory and office space, with initial or remaining terms of one year or more as of March 31, 2025 are as follows:

	March 31,<br><br>2025<br><br>Operating<br><br>Lease Commitments

2029 & Thereafter		369
Total	$	2,827
Less imputed interest		(265	)
Total operating lease liabilities	$	2,562

For the largest lease component, the Company has three facilities with our headquarters and primary engineering and operational functions located in Redmond, Washington. Our two subsidiary facilities in Munich, Germany and Shanghai, China provide extended worldwide sales, service, engineering and operation services. The components of our lease expense for the three months ended March 31, 2025 and 2024 include facility related operating lease costs of $182,000 and $208,000, respectively, and short-term lease costs of $9,500 and $9,400, respectively. There were no new operating leases during the three months ended March 31, 2025.

The Redmond, Washington headquarters facility lease runs to October 31, 2029, at approximately 20,460 square feet. The lease for the facility located in Shanghai, China runs to October 31, 2027, at approximately 19,400 square feet. The lease for the facility located near Munich, Germany runs to August 2027, at approximately 4,895 square feet.

The following table presents supplemental balance sheet information related to leases as of March 31, 2025 and December 31, 2024:

	Balance at<br><br>March 31,<br><br>2025		Balance at<br><br>December 31,<br><br>2024
(in thousands)

Lease liability-short term (Other accrued liabilities)		655		640
Lease liability-long term (Operating lease liabilities)		1,906		2,064

At March 31, 2025, the weighted average remaining lease term is 3.9 and the weighted average discount rate used is 5%.

NOTE 6– OTHER COMMITMENTS

We have purchase obligations for inventory and production costs as well as other obligations such as capital expenditures, service contracts, marketing, and development agreements. Arrangements are considered purchase obligations if a contract specifies all significant terms, including fixed or minimum quantities to be purchased, a pricing structure and approximate timing of the transaction. Most arrangements are cancelable without a significant penalty, and with short notice, typically less than 90 days. As of March 31, 2025, we had four contracts with a commitment of approximately $469,000 to be paid within one year and $1,473,000 to be paid beyond one year.

Table of Contents

NOTE 7 – CONTINGENCIES

As of March 31, 2025, we were not a party to any legal proceedings or aware of any indemnification agreement claims, the adverse outcome of which in management’s opinion, individually or in aggregate, would have a material adverse effect on our results of operations or financial position.

NOTE 8 – INCOME TAXES

Income tax expense for the first quarter of both 2025 and 2024, primarily related to foreign and minor state taxes.

The effective tax rate differed from the statutory tax rate primarily due to the effect of valuation allowance, as well as foreign taxes. We have a valuation allowance of $8.9 million as of both March 31, 2025 and 2024. As of March 31, for both 2025 and 2024, our deferred tax assets and valuation allowance have been reduced by approximately $444,000 and $434,000, respectively. Given the uncertainty created by our loss history, as well as the volatile and uncertain economic outlook for our industry and capital spending, we have limited the recognition of net deferred tax assets including our net operating losses and credit carryforwards and continue to maintain a valuation allowance for the full amount of the net deferred tax asset balance.

NOTE 9 – EARNINGS PER SHARE

Basic earnings per share is calculated based on the weighted average number of common shares outstanding during each period. Diluted earnings per share is calculated based on these same weighted average shares outstanding plus the effect of potential shares issuable upon assumed exercise of stock options based on the treasury stock method.

Potential shares issuable upon the exercise of stock options are excluded from the calculation of diluted earnings per share to the extent their effect would be anti-dilutive.

The following table sets forth the computation of basic and diluted earnings per share:

	Three Months Ended

The weighted average number of shares outstanding used to compute earnings (loss) per share included the following:

	Three Months Ended
	March 31,<br><br>2025		March 31,<br><br>2024
Restricted Stock Units		84,336		118,903
Performance Stock Units		16,180		2,935
Stock Options		-		174

Options to purchase 200,000 and 12,500 shares were outstanding as of March 31, 2025 and 2024, respectively, but were excluded from the computation of diluted earnings per share for the periods then ended because the options were anti-dilutive.

NOTE 10 – SHARE-BASED COMPENSATION

For share-based awards granted, we have recognized compensation expense based on the estimated grant date fair value method. For these awards we have recognized compensation expense using a straight-line amortization method and reduced for estimated forfeitures.

First quarter 2025 shared-based compensation of $174,000, was $107,000 lower compared to the prior year period due to staff reductions which occurred in the fourth quarter of 2024. The impact on our results of operations of recording share-based compensation, net of forfeitures, for the three months ended March 31, 2025 and 2024 were as follows:

	Three Months Ended
	March 31,<br><br>2025		March 31,<br><br>2024

Cost of goods sold	$	25	$	23
Research and development		48		65
Selling, general and administrative		101		193
Total share-based compensation	$	174	$	281

Equity awards granted during the three months ended March 31, 2025 and 2024 were as follows:

	Three Months Ended
	March 31,<br><br>2025		March 31,<br><br>2024
Restricted Stock Units		10,000		-

Employee RSUs typically vest annually over three or four years and employee Non-Qualified stock options typically vest quarterly over four years and have a six-year exercise period. Non-employee director Restricted Stock Units (“RSUs”) typically vest over the earlier of one year or the next annual meeting of shareholders and Non-Qualified stock options vest over three years and have a six-year exercise period.

Performance Stock Units (“PSUs”) typically cliff vest at the end of the performance period and the performance metric for 2023 awards is cumulative revenue growth over the three-year period ending December 31, 2025 with a cumulative revenue threshold, target, and maximum performance measure. For 2024 awards, the performance metrics included revenue growth, EBITDA and project objective targets over the three-year period ending December 31, 2026.

NOTE 11 –SEGMENT INFORMATION

Data I/O operates as a single segment entity, with the sole objective to design, manufacture, and sell programming systems. We operate in three separate locations — Redmond, Washington; Shanghai, China; and Munich, Germany — these locations function as part of a single, integrated business and all operations are strategically aligned to support this objective.

The accounting policies of the programming system segment are the same as those described in the summary of significant accounting policies. The measure of segment assets is reported on the balance sheet as total consolidated assets.

Our chief operating decision maker (CODM) is the President/CEO who reviews the company’s financial performance on a consolidated basis without distinguishing between different business lines or geographic areas for the purpose of making operating decisions, allocating resources and evaluating financial performance. Financial performance is assessed using operating results, actual net income vs. plan, balance sheet fluctuations, and other key performance indicators. Significant single segment expense categories that are provided to the chief operating decision maker and included in the reported segment operating profits are outlined in the following table:

Management's Discussion and Analysis of Financial Condition and Results of Operations

General

FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. This Act provides a “safe harbor” for forward-looking statements to encourage companies to provide prospective information about themselves as long as they identify these statements as forward-looking and provide meaningful cautionary statements identifying important factors that could cause actual results to differ from the projected results. All statements other than statements of historical fact made in this Quarterly Report on Form 10-Q are forward-looking. In particular, statements herein regarding economic outlook; industry prospects and trends; expected business recovery; industry partnerships; future results of operations or financial position; future spending; expected expenses, breakeven revenue point; expected market decline, bottom or growth; market acceptance of our newly introduced or upgraded products or services; the sufficiency of our cash to fund future operations and capital requirements; development, introduction and shipment of new products or services; changing foreign operations; taxes, trade issues and tariffs; expected inventory levels; expectations for unsupported platform or product versions and related inventory and other charges; supply chain expectations; semiconductor chip shortages and recovery; and any other guidance on future periods are forward-looking statements. Forward-looking statements reflect management’s current expectations and are inherently uncertain. Although we believe that the expectations reflected in these forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance, achievements, or other future events. Moreover, neither Data I/O nor anyone else assumes responsibility for the accuracy and completeness of these forward-looking statements. We are under no duty to update any of these forward-looking statements after the date of this Annual Report. The Reader should not place undue reliance on these forward-looking statements. The following discussions and the 2024 Annual Report on Form 10-K section entitled “Risk Factors – Cautionary Factors That May Affect Future Results” describe some, but not all, of the factors that could cause these differences.

OVERVIEW

Data I/O continued to make progress in key operational areas during the first quarter, despite a challenging global economic environment. The period represents a first step in proving the growth and market expansion strategies being implementing over the past several months. The Company achieved strong first quarter results, reporting increases in revenue, net income and EBITDA on a sequential and year-over-year comparison basis. At the same time, efficiency improvements and streamlining operations resulted in a lower cost basis for manufacturing and overhead.

Furthermore, we are encouraged to see customers increase the utilization of their existing systems which results in a greater need for engineering and maintenance services and heightened demand for consumable adapters, which represent a high margin source of revenue. We continue to grow our pipeline of opportunities beyond the automotive sector including a revitalization of our activities with semiconductor companies and forging strategic product development relationships with leading firms serving the memory and microcontroller sectors. Combined with continued efforts to expand our market reach, we expect to deliver revenue growth through end market diversification and an enhanced consultative sales process.

As the tariff and trade scenarios evolve, Data I/O is well prepared having implemented a resilient supply chain with dual manufacturing capabilities in both the United States and China during COVID which provides an advantage to manage emerging tariff policies. With the flexibility to manufacture at either location, we are well positioned to cost-effectively support customers globally. Efforts are underway to enhance our redundancies between our two manufacturing locations. Additional manufacturing locations are being considered for placement within our European headquarters in Germany and with select distribution partners.

Significant progress has been made in a short period of time against a backdrop of significant economic and cross-border trade uncertainty. We remain cautious given the near-term headwinds, as this has created additional strain on the economy and stalled capital investments. We remain focused on setting the business up for sustainable growth by driving innovation, enhancing our products and improving our value proposition.

CRITICAL ACCOUNTING POLICY JUDGMENTS AND ESTIMATES

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires that we make estimates and judgments, which affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related to revenue recognition, sales returns, credit losses, inventories, income taxes, warranty obligations, restructuring charges, contingencies such as litigation and contract terms that have multiple elements and other complexities typical in the capital equipment industry. We base our estimates on historical experience and other assumptions that we believe are reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

We believe the following critical accounting policies affect the more significant judgments and estimates used in the preparation of our financial statements:

Revenue Recognition: Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers (ASC 606) provides a single, principles-based, five-step model to be applied to all contracts with customers. It generally provides for the recognition of revenue in an amount that reflects the consideration to which the Company expects to be entitled, net of allowances for estimated returns, discounts or sales incentives, as well as taxes collected from customers when control over the promised goods or services are transferred to the customer.

We enter into arrangements with multiple performance obligations that arise during the sale of a system that could include hardware, software, installation, services and support and extended maintenance components. We allocate the transaction price of each element based on the relative selling price. Relative selling price is based on the selling price of the standalone system. Installation, services and support costs are based on the discount given to distributors who perform these services. For software maintenance performance obligations, we use the charge for annual software maintenance renewals after the expiration of the initial warranty coverage. Revenue is recognized on the system based on shipping terms, software based on delivery, installation and services based on completion of work and software maintenance and extended warranty support ratably over the term of the agreement, typically one year.

When we license software separately, we recognize revenue upon the transfer of control of the software, which is generally upon delivery, provided that only immaterial items in the context of the contract with the customer remain on our part and substantive acceptance conditions, if any, have been met.

Table of Contents

Allowance for Credit Losses: Allowance for credit losses is based on our assessment of the losses collectively expected for the future, as well as collectability of specific customer accounts and the aging of accounts receivable. If there is deterioration of a major customer’s credit worthiness or actual defaults are higher than historical experience, or events forecast that collectively indicate some impairment is expected, our estimates of the recoverability of amounts due to us could be adversely affected.

Inventory: Inventories are stated at the lower of cost or net realizable value. Adjustments are made to standard cost, which approximates actual cost on a first-in, first-out basis. We estimate reductions to inventory for obsolete, slow-moving, excess and non-salable inventory by reviewing current transactions and forecasted product demand. We evaluate our inventories on an item-by-item basis and record inventory adjustments accordingly. If there is a significant decrease in demand for our products, uncertainty during product line transitions, or a higher risk of inventory obsolescence because of rapidly changing technology and customer requirements, we may be required to increase our inventory adjustments and our gross margin could be adversely affected.

Warranty Accruals: We accrue for warranty costs based on the expected material and labor costs to fulfill our warranty obligations. If we experience an increase in warranty claims, which are higher than our historical experience, our gross margin could be adversely affected.

Tax Valuation Allowances: Given the uncertainty created by our loss history, as well as cyclical economic outlook for our industry, capital and geographic spending, as well as income and current net deferred tax assets by entity and country, we expect to continue to limit the recognition of net deferred tax assets and accounting for uncertain tax positions and maintain the tax valuation allowances. At the current time, we expect, therefore, that reversals of the tax valuation allowance will take place as we are able to take advantage of the underlying tax loss or other attributes in carry forward or their use by future income or circumstances allow us to realize these attributes. The transfer pricing and expense or cost sharing arrangements are complex areas in which judgments, such as the determination of arms-length arrangements, can be subject to challenges by different tax jurisdictions.

Share-based Compensation: We account for share-based awards made to our employees and directors, including employee stock option awards, performance stock unit awards and restricted stock unit awards, using the estimated grant date fair value method of accounting. For options, we estimate the fair value using the Black-Scholes valuation model and an estimated forfeiture rate. Restricted stock unit awards and performance stock unit awards are valued based on the average of the high and low price on the date of the grant and an estimated forfeiture rate. For options, performance and restricted stock unit awards, expense is recognized as compensation expense on the straight-line basis. Employee Stock Purchase Plan (“ESPP”) shares were issued under provisions that do not require us to record any equity compensation expense.

Software and maintenance		896			1.0	%		887
Total	$	6,176			1.3	%	$	6,099

Net sales in the first quarter of 2025 were $6.2 million, as compared with $6.1 million in the prior year period and $5.2 million in the fourth quarter of 2024. The improvements were driven by business recovery and backlog deliveries in the Americas and Europe with growth from the prior year period of 32% and 44%, respectively. Asia revenue declined 40% due to strong prior year performance and bookings delay due to trade, tariffs and economic uncertainties.

New bookings activities were strong at the start and slowed at the end of the first quarter as customers delayed purchase decisions due to global trade and tariff concerns and related automotive electronics uncertainty. First quarter 2025 bookings were $4.6 million, up from $4.1 million in fourth quarter 2024 and down from $8.1 million in first quarter 2024 due to a large $2.8 million contract from a single customer for multiple system deliveries that has spanned nearly 15 months. Backlog on March 31, 2025 was $2.9 million, down $0.6 million from December 31, 2024. Additionally, deferred revenue was approximately $1.5 million on March 31, 2025.

On a geographic basis, international sales represented approximately 88% of total net sales for the first quarter of 2025 compared with 96% in the prior year period. Total equipment sales were 54% of revenues, adapters were 32% and software and services revenues were 14% of revenues in the first quarter of 2025 compared with 55% and 30% and 15% respectively for the first quarter of 2024. Automotive electronics represented 66% of orders followed by 26% for IoT and 8% for programming centers for the first quarter of 2025.

(in thousands)
Gross margin	$	3,188			(1.0	%)	$	3,220
Percentage of net sales		51.6	%					52.8	%

Gross margin as a percentage of sales in the first quarter of 2025 was 51.6% as compared to 52.8% in the same period last year and 52.2% in the fourth quarter of 2024. The change in gross margin percentage primarily reflects a higher mix of system sales revenue and lower spending absorption from related inventory reductions in the first quarter of 2024.

RESEARCH AND DEVELOPMENT

	Three Months Ended

Research and development	$	1,515			(4.2	%)	$	1,582
Percentage of net sales		24.5	%					25.9	%

Research and development (“R&D”) expenses decreased in the first quarter of 2025 as compared to the same period in 2024. The slight decrease is due to transition from prior to new R&D programs and the associated changes in project and outside services spending.

SELLING, GENERAL AND ADMINISTRATIVE

Percentage of net sales		33.2	%					41.0	%

Selling, General and Administrative (“SG&A”) expenses were lower in the first quarter of 2025 as compared to the same period in 2024. First quarter spending reduction reflects primarily lower sales commissions related to lower first quarter bookings and lower compensation expenses from headcount reductions which occurred in fourth quarter 2024. Continued efficiency improvements and cost reduction efforts remain a focus, offset in part by inflationary increases and seasonal first quarter public company costs.

Interest income	$	38		(52.5	%)	$	80

Interest income was lower in the first quarter of 2025 compared to the same period in 2024 due to lower interest rates and invested balances.

INCOME TAXES

(in thousands)
Income tax benefit (expense)	$	(21	)		(48.8	%)	$	(41	)

Income tax benefit (expense) for the first quarter of 2025 and 2024 primarily related to foreign and state taxes.

The effective tax rate differed from the statutory tax rate primarily due to the effect of valuation allowances, as well as foreign taxes. We have a valuation allowance of $8.9 million as of March 31, 2025. As of March 31, for both 2025 and 2024, our deferred tax assets and valuation allowance have been reduced by approximately $444,000 and $434,000, respectively. Given the uncertainty created by our loss history, as well as the volatile and uncertain economic outlook for our industry and capital spending, we have limited the recognition of net deferred tax assets including our net operating losses and credit carryforwards and continue to maintain a valuation allowance for the full amount of the net deferred tax asset balance.

Financial Condition

LIQUIDITY AND CAPITAL RESOURCES

	March 31,<br><br>2025		Change			December 31,<br><br>2024
(in thousands)
Working capital	$	16,014	$	(71	)	$	16,085

At March 31, 2025, our principal sources of liquidity consisted of existing cash and cash equivalents. Cash at $10.5 million increased $159,000 from December 31, 2024 primarily due to higher sales, an improved costs structure and lower inventory levels, partially offset by higher cash expenses paid annually in the first quarter. Correspondingly, working capital of approximately $16.0 million on March 31, 2025, remained relatively flat as compared to December 31, 2024. The Company continues to have no debt.

Although we have no significant capital expenditure plans currently, we expect to continue to carefully make and manage expenditures to support the business. Engineering and production tooling, test equipment and sales demonstration products will continue to be purchased as we develop and release new products. Capital expenditures are expected to be funded by existing and internally generated funds.

As a result of our cyclical and seasonal industry, significant product development, customer support and selling and marketing efforts, we have required working capital to fund our operations. We have tried to balance our spending with our anticipated revenue levels and the goal of profitable operations. We have implemented or have on-going initiatives to reduce material and logistic costs, enhance product quality, increase operational and R&D efficiencies and minimize tax expenses.

We believe that we have sufficient cash or working capital available under our operating plan to fund our operations and capital requirements through the next one-year period, and beyond. Our working capital may be used to fund possible losses, business growth, project initiatives, share repurchases and business development initiatives, including acquisitions, which could reduce our liquidity and result in a requirement for additional cash before that time. Any substantial inability to achieve our current business plan could have a material adverse impact on our financial position, liquidity, or results of operations and may require us to further reduce expenditure and/or seek possible additional financing.

OFF-BALANCE SHEET ARRANGEMENTS

Except as noted in the accompanying consolidated financial statements in Note 5, “Leases” and Note 6, “Other Commitments”, we have no off-balance sheet arrangements.

NON-GENERALLY ACCEPTED ACCOUNTING PRINCIPLES (GAAP) FINANCIAL MEASURES

Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”) was ($272,000) in the first quarter of 2025 compared to ($645,000) in the first quarter of 2024. Adjusted EBITDA, excluding equity compensation (a non-cash item), was ($98,000) in the first quarter of 2025, compared to ($364,000) in the first quarter of 2024.

Non-GAAP financial measures, such as EBITDA and adjusted EBITDA, should not be considered a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. We believe that these non-GAAP financial measures provide meaningful supplemental information regarding the Company’s results and facilitate the comparison of results. A reconciliation of net income to EBITDA and adjusted EBITDA follows:

Controls and Procedures

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Exchange Act) as of the end of the period covered by this report (the “Evaluation Date”). Disclosure Controls are controls and procedures designed to reasonably assure that information required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure Controls are also designed to reasonably assure that such information is accumulated and communicated to our management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of the Evaluation Date, our disclosure controls and procedures were not effective due to a material weakness in our internal control over financial reporting.

As previously reported, we identified material weakness in our internal controls over financial reporting as of December 31, 2024. The material weakness related to user access and segregation of duties for the information technology system that support the Company’s financial reporting process. Not withstanding this material weakness, we have performed additional procedures to enable management to conclude that our consolidated financial statements included in this Form 10-Q fairly present in all material respects our financial condition and results of operations for the period ended March 31, 2025.

In response to the material weakness, we have made and will continue to expand the remediations needed to address this weakness. Management and the Audit Committee will monitor these remedial measures and the effectiveness of our overall control environment. A material weakness will not be considered remediated, however, until the applicable controls operate for a sufficient period of time and Management concludes, through testing, that these controls are operating effectively.

CHANGES IN INTERNAL CONTROLS

There were no changes made in our internal controls during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting which is still under the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control – Integrated Framework (2013).
