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”, the “Company”) 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, 2026 and March 31, 2025, 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, 2025, 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, 2026, are not necessarily indicative of the results that may be expected for the year ending December 31, 2026.

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, 2025 (filed with the SEC on April 16, 2026). 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. These systems are standard products with published product specifications and are configurable with standard options. The evidence that these systems could be deemed 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.

We enter into arrangements with multiple performance obligations that arise during the sale of a system that could include hardware, software, services and support and extended maintenance components. We allocate the transaction price of each element based on the relative selling price of each performance obligation. For hardware, we determine our best estimate of selling price based on an expected cost-plus-a-margin approach. For the service and support performance obligations, we estimate the standalone selling price using the adjusted market assessment approach, which considers observable market pricing, discounting practices, and prices charged for comparable standalone arrangements. For software maintenance performance obligations, we determine our best estimate of selling price based on observable standalone sales of annual software maintenance renewals. Revenue is recognized on the system based on shipping terms, software based on delivery, services based on completion of work, and software maintenance and extended warranty support ratably over the term of the agreement, typically one year.

Table of Contents

We record deferred revenue as any non-refundable amounts that are primarily related to prepayments from customers, which is recognized as revenue as or when the performance obligations are satisfied. We have elected the practical expedient to omit disclosure of the amount of the transaction price allocated to remaining performance obligations for contracts with an expected contract length of one year or less.

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 an equipment warranty and are conducted as sales in our normal and ordinary course of business. 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, 2026		March 31, 2025 (as Revised)
(in thousands)
Platform Sales	$	625	$	3,054
Adapter Sales		1,520		1,943
Software and Services Sales*		1,105		1,179
Total	$	3,250	$	6,176

* includes service and parts sales associated with equipment service contracts

The Company identified an error in the prior‑year disaggregated revenue amounts. As a result, the 2025 revenue by major category amounts have been revised. The correction did not impact the Company’s previously reported consolidated balance sheets, statements of operations, comprehensive income (loss), or statements of cash flows. See: Note 12 for additional information regarding the revision of prior‑period disaggregated revenue amounts.

Table of Contents

Share-Based Compensation

All share-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.

On July 4, 2025, the One Big Beautiful Bill Act (Act) was signed into law. The Act makes permanent key elements of the Tax Cuts and Jobs Act, including 100 percent bonus depreciation, domestic research cost expensing, increases the AMIC to 35 percent from 25 percent and modifications to the international tax framework. The Act includes multiple effective dates, with certain provisions effective in 2025 and others phased in through 2027. We continue to evaluate the impact of the Act's provisions that will take effect in future years. As a result of this legislation, the Company is deducting its domestic Section 174A expenditures beginning in the 2025 taxable year.

New Accounting Pronouncements – Standards Issued and Not Yet Implemented

In November 2024, the 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. This standard is effective for the Company’s annual reporting period beginning January 1, 2027, and interim reporting periods beginning January 1, 2028. Early adoption is permitted. The Company is currently evaluating the effects of adopting this new accounting guidance.

NOTE 2 – INVENTORIES

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.

Total operating lease liabilities	$	1,933

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, 2026, include facility related operating lease costs of $189,000, and short-term lease costs of $7,800. In the prior year, components of our lease expense for the three months ended March 31, 2025, include facility related operating lease costs of $182,000, and short-term lease costs of $9,500. There were no new operating leases during the three months ended March 31, 2026.

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, 2026, and December 31, 2025:

	Balance at March 31, 2026		Balance at December 31, 2025

Right-of-use assets (Long-term other assets)	$	1,836	$	2,005
Lease liability-short term (Other accrued liabilities)	$	698	$	690
Lease liability-long term (Operating lease liabilities)	$	1,235	$	1,411

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, 2026, we had confirmed contracts with a commitment of approximately $596,000 to be paid within one year and $480,000 to be paid beyond one year.

NOTE 7 – CONTINGENCIES

As of March 31, 2026, 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 2026 and 2025 primarily related to foreign and minor state taxes.

Benefit or provision for income taxes for the three months ended March 31, 2026, and 2025, was a provision of $0 and $21,000, respectively, and the effective tax rates for these periods were 0% and 5.82%, respectively. The difference between our effective tax rates for the three months ended March 31, 2026 and 2025, and the U.S. statutory rate of 21% was primarily attributable to the impact of a full valuation allowance on our net deferred tax assets, as well as foreign taxes. Our consolidated effective tax rate decreased for the three months ended March 31, 2026, compared to the same period in the prior year primarily due to operational results in the first quarter of 2026.

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:

Restricted Stock Units		104,994		84,336
Performance Stock Units		18,081		16,180
Stock Options		685		-

Options to purchase 200,000 and 200,000 shares were outstanding as of March 31, 2026 and 2025, 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.

Equity awards granted during the three months ended March 31, 2026 and 2025 were as follows:

	March 31, 2026		March 31, 2025

Restricted Stock Units		-		10,000
Performance Stock Units		-		-

Employee Restricted Stock Units (“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 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. There were no Performance Stock awards granted in 2025 or 2026.

NOTE 11 – SEGMENT INFORMATION

Data I/O operates as a single segment entity, to design, manufacture, and sell programming systems and services. 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/Chief Executive Officer 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 CODM and included in the reported segment operating profits are outlined in the following table:

	Three Months Ended
(in thousands)	March 31, 2026			March 31, 2025

NOTE 12 – PRIOR PERIOD REVISION

The Company identified an error in the prior‑year disaggregated revenue amounts of net sales by type. As such, the Company has revised the net sales by type for the quarter ended March 31, 2025. This correction affected only the disaggregation of net sales among Platform, Adapter, and Software and Services sales and did not impact the Company’s previously reported consolidated balance sheets, statements of operations, comprehensive income (loss), or statements of cash flows. While the total revenue was not affected, the Company has revised the presentation of net sales by type for the quarter ended March 31, 2025 to enhance comparability.

Effect of Revision

NOTE 13 – SUBSEQUENT EVENTS

Subsequent to quarter end, the Company entered into a definitive securities purchase agreement with institutional investors for aggregate gross proceeds of approximately $9.0 million, consisting of a combination of common stock, convertible debentures, and warrants. The transaction is subject to customary closing conditions, including regulatory approvals, and is expected to close in the second quarter of 2026. Nasdaq rules will limit the number of shares that may be issued upon conversion or exercise of the convertible debentures and warrants absent shareholder approval.

FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains 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 industry prospects and trends; expected business recovery; industry partnerships; future results of operations or financial position; future spending; expected expenses, breakeven revenue point; cybersecurity risk management and costs; expected market decline, bottom or growth; the development of the Edge AI market; 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; strategic transformation progress and timeline; ERP implementation timeline; potential acquisitions; and the 2026 organic growth framework; taxes, trade issues and tariffs; expected inventory levels; expectations for unsupported platform or product versions and related inventory and other charges; Russian invasion of Ukraine impacts; Israel – Hamas war impacts; 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 Quarterly Report. The reader should not place undue reliance on these forward-looking statements. The following discussions and the 2025 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 evolve its business through the first quarter of 2026, despite a challenging global economic environment. Slower uptake of new initiatives through the early part of the quarter negatively impacted revenue growth, but momentum began to build towards quarter-end. Meanwhile, management took steps to realign costs, leveraging operating efficiencies and internal AI deployments and select, targeted spending cuts to reduce costs.

Our customers’ end markets have seen some weakening of demand which has affected sell-through of microcontrollers, security ICs and memory devices, which we believe has been partially offset by customers’ increased utilization of their existing systems. The net effect has been some greater need for engineering and maintenance services but also some lumpiness in demand for consumable adapters. Overall demand for capital equipment continued to be negatively impacted by global trade and tariff negotiations throughout most of the first quarter. However, the Company’s ongoing supply chain planning and other actions have helped mitigate the impact of new tariffs, trade and inflationary pressures, including shifting material sourcing and product manufacturing.

We continue to focus on expanding our pipeline of opportunities beyond the automotive sector including a revitalization of our activities with semiconductor companies. 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. In the quarter, we announced an important strategic relationship with IAR in the security space that we believe will expand the reach, applicability and addressable market for both companies.

Significant operational and product 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, but are increasingly encouraged by later-quarter activity levels. We remain focused on setting the business up for sustainable growth by driving innovation, enhancing our products and improving our value proposition.

Table of Contents

At the same time, we are focused on increasing our efficiency in delivering our products and services, and to that end we have sought to streamline and better align our operations. Notably, in the first quarter of 2026, we made some strategic realignments around our Germany office which we expect to yield material cost savings and efficiencies. Employee-related costs related to the Germany realignment and expensed in the first quarter amounted to approximately over $1 million, primarily for legal work and employee severance. We expect to continue to review our operations in Germany as well as the U.S. and China operations with an eye to improving operational efficiency worldwide.

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.

There have been no changes to our critical accounting policies and estimates as compared to the critical accounting policies and estimates discussed in the Annual Report on Form 10-K for the year ended December 31, 2025, which was filed with the SEC on April 16, 2026, as described in Note 1. Description of Business and Summary of Significant Accounting Policies to the condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Total	$	3,250		(47.4	)%	$	6,176

* includes service and parts sales associated with equipment service contracts

Net sales in the first quarter of 2026 were $3.3 million, compared with $6.2 million in the prior year period. Overall demand for capital equipment continued to be negatively impacted by ongoing global trade and tariff negotiations throughout most of the first quarter of 2026. Net sales of consumable adapters and services revenue represented 81% of total revenue and provide a stable base of recurring revenue.

Total platform sales in the first quarter of 2026 were 19% of revenues, adapter sales were 47% and software and services sales revenues were 34% of revenues compared with 49% and 32% and 19% respectively in the first quarter of 2025. On a geographic basis, international sales represented approximately 46% of total net sales for the first quarter of 2026 compared with 88% in the prior year period.

Table of Contents

Bookings increased in the latter half of the first quarter as customers had been delaying purchase decisions amid ongoing global trade and tariff concerns and as sales processes disrupted by the ransomware incident resumed. First quarter 2026 bookings were $4.2 million, up from $3.1 million in the fourth quarter 2025 and down from $4.6 million in the first quarter 2025.

Backlog at March 31, 2026, was $2.6 million, up from $1.6 million at the end of the prior quarter. Deferred revenue was $1.5 million on March 31, 2026, and $1.5 million on December 31, 2025.

GROSS MARGIN

	Three Months Ended
	March 31, 2026			Change			March 31, 2025
(in thousands)
Gross margin	$	1,609			(49.5	)%	$	3,188
Percentage of net sales		49.5	%					51.6	%

Gross margin as a percentage of sales in the first quarter of 2026 was 49.5% as compared to 51.6% in the same period last year. Overall gross margins recovered sequentially as direct material costs remained steady and consistent with prior periods. Margins declined year-over-year as overheads and other fixed costs were spread over a smaller revenue base. Ongoing supply chain planning and other actions have been mitigating the impact of new tariffs, trade and inflationary pressures, including shifting material sourcing and product manufacturing.

RESEARCH AND DEVELOPMENT

	Three Months Ended
	March 31, 2026			Change			March 31, 2025
(in thousands)
Research and development	$	1,291			(14.8	)%	$	1,515
Percentage of net sales		39.7	%					24.5	%

Research and development (“R&D”) expenses decreased in the first quarter of 2026 as compared to the same period in 2025. The decrease is due primarily to a reduction in expenses related to headcount and outside services for projects completed in 2025.

SELLING, GENERAL AND ADMINISTRATIVE

Percentage of net sales		106.5	%					33.2	%

Selling, General and Administrative (“SG&A”) expenses were higher in the first quarter of 2026 as compared to the same period in 2025. The year-over-year increase in SG&A expense was largely driven by a number of one-time expenses, most notably reorganization expenses related to the strategic reconfiguration of the Company’s Munich operations. Continued efficiency improvements and cost reduction efforts remain a focus.

Share-based compensation	$	77		(55.7	)%	$	174

First quarter 2026 share-based compensation of $77,000 was $97,000 lower compared to the prior year period due to staff reductions and retirements since the fourth quarter of 2024.

Income tax benefit (expense)	$	-		(100	)%	$	(21	)

Income tax expense for the first quarter of both 2026 and 2025, primarily related to foreign and minor state taxes.

Income tax provision of $0 and $21,000 were recognized for the three months ended March 31, 2026 and 2025, respectively, and the effective tax rates for these periods were 0% and 5.82%, respectively. The difference between our effective tax rates for the three months ended March 31, 2026 and 2025, and the U.S. statutory rate of 21% was primarily attributable to the impact of a full valuation allowance on our net deferred tax assets, as well as foreign taxes. Our consolidated effective tax rate decreased for the three months ended March 31, 2026, compared to the same period in the prior year primarily due to operational results in the first quarter of 2026.

Working capital

(2,973

)

12,270

Working capital decreased by $3.0 million during 2026, primarily due to the revenue decline and resulting operating loss. Our current ratio was 2.6 and 3.5 for March 31, 2026 and December 31, 2025, respectively.

At March 31, 2026, our principal sources of liquidity consisted of existing cash and cash equivalents. Cash at $5.7 million decreased $2.2 million from December 31, 2025, primarily due to one-time expenses and investments in the first quarter, partially offset by an otherwise improved cost structure, lower inventory levels, and currency effects on overseas cash balances. Correspondingly, working capital of approximately $9.3 million on March 31, 2026, was down $3.0 million as compared to December 31, 2025. The Company continues to have no debt.

Table of Contents

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. If the Company determines to pursue significant acquisitions or business development initiatives, the Company may need to raise additional capital. If additional capital is required, the Company will review the amounts and options to raise capital at that time, but future financing would most likely be through debt and equity offerings. 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, “Operating Lease Commitments” 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 ($3,070,000) in the first quarter of 2026 compared to ($272,000) in the first quarter of 2025. Adjusted EBITDA, excluding share-based compensation (a non-cash item), was ($2,993,000) in the first quarter of 2026, compared to ($98,000) in the first quarter of 2025.

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:

Not applicable.

Item 4. 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 Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as appropriate to allow timely decisions regarding required disclosure. Based upon that evaluation, the CEO and CFO 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 which was identified and discussed in more detail in our annual report on Form 10-K for the year ended December 31, 2025.

As previously reported, we identified material weakness in our internal controls over financial reporting as of December 31, 2025. The material weakness related to segregation of duties and to the completeness and accuracy of internally generated reports used in the preparation of the disaggregated revenue footnote as of December 31, 2025. Notwithstanding 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, 2026.

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.

Table of Contents

CHANGES IN INTERNAL CONTROLS

Subsequent to the identification of the material weakness discussed in the annual report on Form 10-K for the year ended December 31, 2025, management has continued to implement remediation actions designed to address the underlying control deficiencies, including enhancing review procedures and increasing management oversight over financial reporting activities. These actions are intended to improve the design and operation of the Company’s internal control environment. Management believes these remediation efforts appropriately address the root causes of the material weakness; however, the material weakness will not be considered remediated until the relevant controls have operated for a sufficient period of time and management has concluded, based on testing, that the controls are operating effectively.

This shutdown and any such future events may result in loss of revenue; business disruptions (such as the inability to timely process shipments); and significant remediation costs.
