***OVERVIEW***

Data I/O Corporation is a global leader in data programming and provisioning solutions for flash memory, microcontrollers and security integrated circuits. The Company designs, manufactures and sells programming and security deployment systems used by electronics manufacturers in automotive, Internet-of-Things, industrial, medical, wireless and consumer electronics applications. Since 1972, the Company has enabled the design and manufacture of electronic products through innovative programming solutions, and today its customers use Data I/O's security deployment and programming systems to reliably, securely and cost-effectively bring innovative new products to life. The Company's global operations include manufacturing and engineering facilities in Redmond, Washington and Shanghai, China, with additional sales and support operations in Munich, Germany.

The year ended December 31, 2025 was a pivotal period for the Company, defined by a comprehensive strategic transformation executed under the leadership of President and CEO William Wentworth, who assumed the role in the fourth quarter of 2024. The transformation was designed around six strategic priorities: modernizing the Company's go-to-market strategy, investing in the core technology platform, strengthening customer relationships, optimizing business operations and IT infrastructure, improving operational processes, and deploying artificial intelligence across the organization. As the Company enters 2026, management believes the transformation is approximately one year ahead of schedule relative to its original multi-year plan.

A central element of the transformation has been expanding the Company's addressable market. Historically, Data I/O served the relatively narrow market for offline semiconductor programming equipment, where demand is predominantly tied to customers' capital expenditure budgets and capacity expansion decisions. The Company is now repositioning itself to serve the significantly larger data provisioning market, which encompasses the programming, configuration, and testing of connected devices across the full manufacturing lifecycle. This expanded market opportunity includes services and solutions for programming at test and support for the growing Edge AI ecosystem. Management believes the broader data provisioning market represents a meaningfully larger opportunity than the traditional programming equipment market segment the Company has historically served.

Subsequent to year end, in February 2026, the Company announced a collaboration with IAR, a global leader in embedded development tools and security solutions, to combine IAR's security expertise with Data I/O's provisioning expertise. The collaboration is intended to create a frictionless solution that reduces the complexity inherent in current device provisioning approaches, simplifying the process of securely programming and provisioning devices across global manufacturing supply chains. This collaboration is an early example of the Company's strategy to build partnerships that extend its platform into adjacent areas of the data provisioning value chain.

The buildout of Edge AI represents a significant emerging growth driver for the Company. Autonomous systems, connected vehicles, industrial IoT devices and smart infrastructure all require increasing volumes of data to be economically and securely provisioned into semiconductor devices at the various points in the manufacturing process. As the proliferation of AI-enabled devices at the network edge accelerates, the demand for high-throughput, secure programming and provisioning solutions is expected to grow substantially. The Company observed encouraging early indicators of this trend during the fourth quarter of 2025 and into early 2026, with new customer logos engaging on definitive production timelines for Edge AI applications. Management believes the convergence of Edge AI buildout and increasing device complexity positions the Company favorably for sustainable long-term growth.

During 2025, the Company deployed artificial intelligence across all functional departments to accelerate operations and reduce costs. AI-enabled efficiencies were a key contributor to a 7% reduction in recurring operating expenses, from an annualized run rate of approximately $26.7 million at the time of the CEO transition in November 2024 to approximately $24.8 million by year end 2025. The Company has identified plans for an additional $1.0 million of annual run rate savings to be realized within the first half of 2026. AI tools were applied to software engineering to accelerate programming algorithm development and device support, ERP implementation planning and data migration, customer support and service processes, and internal business operations including financial reporting and analysis. Management believes these AI capabilities enabled the Company to accomplish its transformation objectives significantly faster than would have been achievable through traditional approaches, and that ongoing AI deployment will continue to yield productivity gains and competitive advantages.

The Company has turned its strategic attention to broadening and stabilizing its business model. Historically, Data I/O's revenues have been overwhelmingly tied to capital expenditure cycles in programming equipment, making the business highly cyclical and dependent on customers' capacity expansion decisions. The Company is making concerted efforts to reduce its dependence on the automotive electronics sector, historically the Company's largest end market. Automotive electronics represented approximately 64% of 2025 bookings, compared to 59% in 2024. More broadly, the Company is focused on developing a more balanced revenue model that incorporates recurring services and consumables revenues, including adapter sales, software services, and programming-at-test service offerings. For the full year 2025, consumable adapters and services represented 58% of total revenue, providing a more stable and recurring base, while platform sales represented 42% of total revenue. Deferred revenue decreased to approximately $1.5 million at December 31, 2025 from $1.6 million at December 31, 2024.

For the full year ended December 31, 2025, the Company reported net sales of $21.5 million, compared to $21.8 million in 2024.

Bookings for the full year 2025 were $18.6 million, a decrease of 17% from $22.5 million in 2024, with backlog at December 31, 2025 of $1.6 million. Regionally, 2025 bookings were strongest from customers throughout Asia, while North America demand for bookings was consistent with the prior year though tailing off in the fourth quarter and Europe declined more generally, reflecting both the ongoing automotive downturn and the Company's deliberate efforts to diversify its customer base into adjacent markets. Despite the near-term booking softness, the Company observed very encouraging customer activity in the fourth quarter 2025 and into early 2026, with new customer engagements and definitive production timelines providing increased confidence in the demand environment heading into the new year.

Looking ahead, the Company has established a 2026 business framework that encompasses organic revenue growth only, from which management sees a path to positive operating cash flows. Inorganic growth opportunities, while actively being evaluated, are not incorporated into this framework and would be incremental to the organic plan. The framework is supported by the convergence of the Company's platform investments, expanding market opportunities in data provisioning and Edge AI, the strategic transformation progress realized in 2025, improved operational capabilities and a strengthened leadership team. The Company's balance sheet provides a solid foundation, with $7.9 million in cash and no debt as of December 31, 2025. Management made deliberate changes to the Board of Directors and executive suite over the past 18 months to ensure the right team is in place to execute this growth plan, and the Company engaged a leading boutique middle-market investment bank to evaluate inorganic growth opportunities aligned with its strategic direction. Based on the progress achieved in 2025 and the early indicators observed in the demand environment, management is confident that 2026 will be a year of growth for Data I/O.

***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.

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 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 2025 and 2024, the impact of capitalization of incremental costs for obtaining contracts was 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, service 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 use the price charged by 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, 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 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 with standard equipment warranty provided 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.

*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.

*Share-based Compensation*: We account for share-based awards provided 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.

---

The Company identified an error in the prior-year disaggregated revenue amounts of net sales by type. As a result, the 2024 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 15 for additional information regarding the revision of prior-period disaggregated revenue amounts.

Net sales for the year ended December 31, 2025 decreased approximately 1.2%, to $21.5 million, compared to $21.8 million in 2024. In 2025, automotive electronics uncertainty persisted and customer capacity expansion slowed, resulting in lower system shipments, notably in Europe, which were partially offset by growth in Asia. Automotive electronics represented 64% of 2025 bookings compared to 59% for 2024. For the full year, consumable adapters and services revenue increased, representing 58% of total revenue and helping mitigate the decline in system sales.

Order bookings in 2025 were $18.6 million, down approximately 17% compared to $22.5 million in 2024, due to similar market challenges noted for revenue. The order backlog on December 31, 2025 was $1.6 million. Additionally, deferred revenue was approximately $1.5 million on December 31, 2025.

**GROSS MARGIN**

| | | | |
|:---|:---|:---|:---|
|  | 2025 | Change | 2024 |
| (in thousands) |  |  |  |
| Gross margin | $10596 | (8.7%) | $11606 |
| Percentage of net sales | 49.3% |  | 53.3% |

---

Gross margin as a percentage of sales for the year ended December 31, 2025, was 49.3%, compared to 53.3% in 2024. The decrease in gross margin as a percentage of sales primarily reflects lower sales volume and lower related absorption of labor and overhead costs.

**RESEARCH AND DEVELOPMENT**

---

Research and development ("R&D") expense increased $291,000 for the year ended December 31, 2025, compared to 2024. The increase was primarily related to increased staff, notably in China.

We invest in R&D to significantly enhance our existing solutions and create new products as markets develop and technologies change. During 2025, we continued to invest in the creation of new and enhancement of existing capabilities for our PSV family of automated systems, LumenX and FlashPAK family of non-automated programmers and related software. In addition to product development, a significant part of R&D spending is on creating algorithm software and support for new devices introduced by the semiconductor companies. Our R&D spending fluctuates based on the number, type, and the development stage of our product initiatives and projects.

**SELLING, GENERAL AND ADMINISTRATIVE**

| Percentage of net sales | 42.7% |  | 38.6% |

---

Selling, General and Administrative ("SG&A") expenses increased approximately $777,000 for the year ended December 31, 2025, compared to 2024. The increase was primarily related to increased legal and accounting fees tied to SEC filings, one-time charges associated with the ransomware incident report on August 16, 2025, and increased spending on infrastructure and security, partially offset by reduced IT spending in other areas. Cost control measures remain in effect.

**INTEREST**

| Interest income | $130 | (52.4)% | $273 |

---

Interest income was lower for the year ended December 31, 2025 compared to 2024 primarily due to lower invested balances.

**INCOME TAXES**

---

| | | | |
|:---|:---|:---|:---|
|  | 2025 | Change | 2024 |
| (in thousands) |  |  |  |
| Income tax (expense) benefit | $(240) | (37.8)% | $(386) |

---

Income tax (expense) decreased by $146,000 for the year ended December 31, 2025 compared to 2024.

In 2025, income tax expense includes $250,000 of deferred income taxes from recording deferred tax liabilities primarily related to outside basis differences in foreign subsidiaries. In 2024, the Company repatriated cash from our China subsidiary resulting in a withholding tax of $337,000.

**INFLATION AND CHANGES IN FOREIGN CURRENCY EXCHANGE RATES**

We recognized foreign currency transaction losses of ($10,000) in 2025 and $58,000 transactions gains in 2024.

Sales and expenses incurred by foreign subsidiaries are denominated in the subsidiary's local currency and translated into U.S. Dollar amounts at average rates of exchange during the year. The transaction gains resulted primarily from translation adjustments to foreign inter-company accounts and U.S. Dollar accounts held by foreign subsidiaries and sales by our German subsidiary to certain customers, which were invoiced in U.S. Dollars. Because approximately 94% of sales are to international markets, volatile exchange rates may also impact our competitiveness and margins. Product and service price increases have been increased in response to cost increases caused by inflation, tariffs and part shortages.

***FINANCIAL CONDITION:***

**LIQUIDITY AND CAPITAL RESOURCES**

Working capital decreased by $3.8 million during 2025, primarily due to the revenue decline and resulting operating loss. Our current ratio was 3.3 and 4.2 for December 31, 2025 and 2024, respectively.

At December 31, 2025, our principal sources of liquidity consisted of existing cash and cash equivalents. Cash at December 31, 2025 and 2024 was $7.9 million and $10.3 million, respectively. The company continues to have no debt.

We expect to continue to carefully make and manage capital expenditures to support our business. We plan to increase our internally developed rental, sales demonstration and test equipment as we develop and release new products. Capital expenditures are currently expected to be funded by existing and internally generated funds.

As a result of the cyclical and seasonal nature of capital expenditure businesses, we require significant working capital to fund our operations. We have continued to manage the geographic posture of our operations to align to our customers' needs and to minimize impacts of exogenous factors such as tariffs. All that said, 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.

We may require additional cash at the U.S. headquarters to support future strategic and operational initiatives., which could cause potential repatriation of cash that is held in our foreign subsidiaries. For any repatriation, there may be tax and other impediments to any repatriation actions. As many repatriations typically have associated withholding taxes, those withheld will be a current tax without generating a current or deferred tax benefit recognition. We are actively tuning our operations and intercompany structures to minimize the need for and impact of any repatriation of monies.

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 reduce expenditure and/or seek possible additional financing.

**OFF-BALANCE SHEET ARRANGEMENTS**

Except as noted in the accompanying consolidated financial statements in Note 7, "Other Commitments" we had no material off-balance sheet arrangements.

**SHARE REPURCHASE PROGRAMS**

Data I/O did not have a share repurchase program in 2025 or 2024.

**NON-GENERALLY ACCEPTED ACCOUNTING PRINCIPLES (GAAP) FINANCIAL MEASURES**

Earnings Before Interest, Taxes, Depreciation, and Amortization ("EBITDA") and Adjusted EBITDA excluding equity compensation and impairment & related charges (non-cash, one-time items) are set forth below. Non-GAAP financial measures 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 our results and facilitate the comparison of results. A reconciliation of net income to EBITDA and Adjusted EBITDA follows:

**Audit Committee**

The Audit Committee appoints, oversees, evaluates, and engages independent certified public accountants for the ensuing year and approves the compensation and other terms of such engagement; reviews the scope of the audit; periodically reviews Data I/O's program of internal control and audit functions; receives and reviews the reports of the independent accountants; and reviews the annual financial report to the directors and shareholders of Data I/O. Each member of the Audit Committee is an independent director, as defined by applicable NASDAQ listing standards and the Sarbanes-Oxley Act of 2002. During 2025 and through the date of this Proxy statement, at least 2 Audit Committee members are "audit committee financial experts" as defined by the applicable SEC rules adopted pursuant to the Sarbanes-Oxley Act of 2002. The Audit Committee met three times during 2025 and recorded 100% committee attendance at such meetings held during their term of service. See the "Report of the Audit Committee" for additional information.

**Corporate Governance and Nominating Committee**

The Corporate Governance and Nominating Committee, or "CGNC", develops, recommends to the Board of Directors, and monitors a set of corporate governance principles applicable to Data I/O. The CGNC seeks qualified candidates to serve on the Board of Directors, recommends them for the Board of Directors' consideration for election as directors at the Annual Meeting of Shareholders and proposes candidates to fill vacancies on the Board of Directors. The CGNC met four times in 2025 and recorded no less than 100% committee attendance at such meetings held during their term of service. The CGNC continues to seek qualified candidates and recommends the director nominees to the Board of Directors. The CGNC identifies, evaluates, and recommends director nominees and Committee assignments which are described in greater detail below.

**Compensation Committee**

The Compensation Committee is composed entirely of independent directors, as defined by applicable NASDAQ listing standards for compensation committees. The Compensation Committee is responsible for setting and administering the policies which govern all of the compensation programs of Data I/O. The Compensation Committee may delegate its authority and duties to subcommittees or individual members of the Compensation Committee as it considers appropriate.

The Compensation Committee makes recommendations to the Board of Directors concerning the compensation of Data I/O's executive officers. The Compensation Committee administers Data I/O's long-term equity incentive plans. The Compensation Committee reviews all employee benefit programs and approves significant changes in major programs and all new programs. The Compensation Committee met four times during 2025 and recorded 100% committee attendance at such meetings held during their term of service.

As authorized by the Compensation Committee charter, the Compensation Committee may retain consultants or other advisors, as well as purchase compensation surveys, to assist in carrying out its responsibilities.

**Consideration of Director Nominees**

The Corporate Governance and Nominating Committee has developed, and the Board has approved, Board Responsibilities and Director Recruitment Objectives, which further outline our directors' roles and responsibilities and desired traits, diversity, characteristics, experience and criteria for selection. The Corporate Governance and Nominating Committee in evaluating and determining whether to recommend a person as a candidate for election as a director consider, in light of the Board Responsibilities and Director Recruitment Objectives, considers the relevant management and/or technology industry experience of potential director candidates (such as experience as chief executive, operations or financial officer, or similar positions); business development, mergers and acquisitions experience; public/corporate board experience, diversity, knowledge of Data I/O; educational experience; commitment to maximizing shareholder value; certain values such as integrity, accountability, judgment and adherence to high performance standards; independence pursuant to applicable guidelines; ability and willingness to undertake the required time commitment to Board functions; shareholder input; and an absence of conflicts of interest with Data I/O.

**Director Diversity**

The Corporate Governance and Nominating Committee also considers issues of diversity, such as diversity of gender, race and national origin, education, professional experience and differences in viewpoints and skills. The CGNC does not have a formal policy on Board diversity; however, the CGNC believes that it is important for Board members to represent diverse viewpoints and comply with specific applicable laws. The composition and quantity of board members may be potentially impacted as we maintain compliance with these and future requirements. In considering candidates for the Board, the CGNC considers the entirety of each candidate's credentials in the context of these standards. With respect to evaluating the nomination of continuing directors for re-election, the CGNC considered each director's contributions to the company as well as the results of the Board of Directors self-evaluations process.

**Identifying Director Nominees; Consideration of Nominees of the Shareholders**

The Corporate Governance and Nominating Committee may employ a variety of methods for identifying and evaluating nominees for directors. The CGNC regularly assesses the size of the Board, the need for particular expertise on the Board, and whether any vacancies on the Board are expected due to retirement or otherwise. In the event that vacancies are anticipated, or otherwise arise, the CGNC considers various potential candidates for director which may come to the CGNC's attention through current Board members, professional search firms, shareholders, or other persons and evaluates these candidates in light of the Board Responsibilities and Director Recruitment Objectives. These candidates are evaluated at regular or special meetings of the CGNC and may be considered at any point during the year.

The Corporate Governance and Nominating Committee will consider candidates recommended by shareholders, when the nominations are properly submitted, under the criteria summarized above in "Consideration of Director Nominees" and in accordance with the procedures described below in "Shareholder Nominations and Proposals for the 2026 Annual Meeting of Shareholders." Following verification of the shareholder status of persons proposing candidates, the CGNC makes an initial analysis of the qualifications of any candidate recommended by shareholders or others pursuant to the criteria summarized above to determine if the candidate is qualified for service on the Data I/O Board of Directors before deciding to undertake a complete evaluation of the candidate. If any materials are provided by a shareholder or professional search firm in connection with the nomination of a director candidate, such materials are forwarded to the CGNC as part of its review. Other than the verification of compliance with procedures and shareholder status, and the initial analysis performed by the CGNC, a potential candidate nominated by a shareholder is treated like any other potential candidate during the review process by the CGNC. For eligible shareholder nominees to be placed on the ballot for the 2026 Annual Meeting of Shareholders, shareholders were required to deliver nominations for proposed director nominees to Data I/O by February 13, 2026. No formal candidate nominations were made by shareholders for election at the 2026 Annual Meeting. Existing Directors were identified as follows: Mr. Wentworth was initially identified by a Board member; Mr. Smith and Mr. Larson were initially identified by discussions with significant shareholders and the Board; Mr. Waszak was initially identified by a current Board member; Ms. Washlow was initially identified and introduced by a former Board member; and Mr. Brown was initially identified and introduced by a former member of management, but is not standing for re-election at the Annual Meeting.

**Board Charters**

The Board of Directors has adopted Corporate Governance and Nominating Committee, Audit Committee and Compensation Committee Charters. All our Charters are reviewed and updated periodically by our Board of Directors. All of our Charters were reviewed during 2025 and again in early 2026 and no changes were made. The current versions of our Charters are posted on the corporate governance page of our website at https://www.dataio.com/Company/Investor-Relations/Corporate-Governance.aspx. All of these Charters are consistent with the applicable requirements of United States security laws and our NASDAQ listing standards.

***Board Role in Risk Oversight***

Our current Board of Directors consists of five independent directors, and one non-independent director, our Chief Executive Officer. Risk oversight is generally handled by our entire Board of Directors, although certain risk oversight areas such as internal control and cyber risk are handled by our Audit Committee, and compensation is handled by our Compensation Committee. The Board leadership structure promotes effective oversight of the Company's risk management for the same reasons that the structure is most effective for the Company in general, that is, by providing the Chief Executive Officer and other members of senior management with the responsibility to assess and manage the Company's day-to-day risk exposure and providing the Board, and specifically the Audit Committee of the Board, with the responsibility to oversee these efforts of senior management.

***Director Independence***

Messrs. Brown, Smith, Larson, and Waszak and Ms. Washlow are independent directors as defined by applicable U.S. Securities and Exchange Commission ("SEC") rules and NASDAQ listing standards.

***Board Leadership Structure***

Ms. Washlow, an independent director, was our Board Chair, until December 3, 2025. Effective, December 3, 2025, the Board appointed Edward Smith, also an independent director, to replace Ms. Washlow as Board Chair. Mr. Wentworth is our Chief Executive Officer, President, and Director.

***Code of Ethics***

We have adopted a Code of Ethics that applies to all directors, officers and employees of Data I/O, including the Chief Executive Officer and Chief Financial Officer. The Code of Ethics is posted on the corporate governance page of our website.

***Section 16(a) Beneficial Ownership Reporting Compliance***

Section 16(a) of the Securities Exchange Act of 1934 requires Data I/O's directors, certain officers and persons who own more than ten percent (10%) of Data I/O's Common Stock ("Reporting Persons") to file with the SEC initial reports of ownership and reports of changes in ownership of Common Stock and other equity securities of Data I/O. Reporting Persons are required by SEC regulations to furnish Data I/O with copies of all Section 16(a) reports.

Based on knowledge of the Company, a Form 4 for William Wentworth reporting a small open market purchase of shares was filed one day late because of a communication delay. Additionally, Charles DiBona's Form 3 and Form 4 were filed approximately one month late on September 30, 2025 as a result of a delay in the issuance of his EDGAR filing codes. Mr. DiBona's Form 3 reported no holdings and his Form 4 reported an initial inducement grant event on August 15, 2025.

***Communications with the Board of Directors***

Shareholders may communicate with the Board of Directors by sending an email to investorrelations@dataio.com or by sending a letter to Data I/O Corporation Board of Directors, c/o the Secretary, 6645 185<sup>th</sup> Ave NE, Suite 100, Redmond, WA 98052. The Secretary will receive the correspondence and forward it to the Chair of the applicable Board of Directors Committee or to any individual director or directors to whom the communication is directed.

**Item 11. Executive Compensation**

The Board has previously adopted a clawback policy which allows us to recover performance-based compensation in the event of an accounting restatement. The policy is incorporated by reference as an exhibit to this Form 10-K. In connection with the preparation of this annual report, we determined that there was an error to previously issued financial statements, which has been corrected in this annual report. As such, we are conducting a clawback analysis in connection with the restatement as required by the Company's policies but have not yet determined if any erroneously awarded compensation was paid based on the restated financial results.

The following table shows compensation paid by Data I/O for services rendered during 2025 and 2024 to each of our named executive officers.

***Shareholder Vote***

At our 2025 Annual Meeting of Shareholders, our shareholders approved, in an advisory vote, the compensation of our Named Executive Officers, as disclosed in the Executive Compensation discussion and analysis, the compensation tables and the related disclosures in our Proxy Statement. The proposal was approved by our shareholders with 92.6% of the votes cast voting "for" approval and 6.6% voting "against" approval. In light of the level of approval by our stockholders, the Compensation Committee considered the result of the vote and did not make changes to our compensation policies or practices specifically in response to the stockholder vote.

***Elements of the Company's Compensation Plan***

Annual executive officer compensation consists of the following elements which are described in more detail below:

· Annual base salary;

· Management Incentive Compensation Plan or "MICP";

· Long-term equity incentives;

· Benefits;

· Perquisites and other perceived benefits; and

· Individual Executive Officers' Performance.

It is the Compensation Committee's policy to set total executive officer compensation at competitive levels based on compensation surveys with similar positions in similar sized company revenue ranges and at levels sufficient to attract and retain a strong, motivated leadership team. Our philosophy for compensation of executive officers is based on the following two principles:

**i.** Executive base compensation levels should be established by comparison of job responsibility to similar positions in comparable companies and be adequate to retain highly-qualified personnel; and

**ii.** Variable compensation should be a critical element of compensation and be set to be comparably competitive and to provide strong incentives to improve performance and shareholder value.

· **Annual Base Salary.** The Compensation Committee establishes a base salary structure for each executive officer position. This structure defines the salary levels and the relationship of base salary to total cash compensation. The Compensation Committee reviews the salary structure periodically.

· **MICP.** The MICP offers each executive officer a performance-based opportunity to earn the variable component of annual cash compensation in an amount tied to a percentage of the executive officer's base salary. The Compensation Committee's philosophy in setting executive MICP percentages and the formulas for MICP payout is to pay above average total compensation for better than average historical or expected financial performance and below average compensation for lower than or average historical or expected financial performance. The percentages of base salary targeted for MICP payout ("the MICP Target") for specific executive officers for a given year are generally the same as the previous year but can be changed by the Compensation Committee on an annual basis. The MICP payout can range from 0% to 200% of each executive's MICP Target based upon the achieved MICP Measures for the period. There was no MICP program for 2025. The 2024 MICP Target amounts for our executive officers based on a full year of their applicable base pay were as follows:

---

| | | | |
|:---|:---|:---|:---|
|  | Executive's<br>MICP<br>2024 Target | Executive's<br>MICP<br>2025 Target | Estimated<br>Payout at Maximum <br>Measure for 2026 |
| William Wentworth | $208200 | N/A | N/A |
| Charles DiBona | N/A | N/A | N/A |
| Gerald Ng | $130000 | N/A | N/A |

---

The Compensation Committee determined for 2024 and again for 2025 that it was critical to emphasize profitability. For the profitability measure: Financial Performance ("FP") which is based on achievement of various levels of operating income as a percentage of revenue. (See below for the Financial Performance Matrix.)

For 2024, it was determined again, profitability was the most critical focus, however the measurement target was modified to EBITDA (Earning Before Interest Taxes Depreciation Amortization) and translated the prior Operating Profit target percentages to EBITDA approximate equivalents. For 2025, Financial Performance continues to be the most critical focus to target incentive compensation on for our Named Executive Officers

The Compensation Committee believes that for 2024, 2025 and 2026, the applicable measures of key results for Data I/O have affected or will affect near-term and long-term shareholder value. A greater or lesser percentage of MICP Target is to be paid based on Data I/O's actual achievement of these measures with the payout target typically based on company financial plans as the Board determines appropriate. For 2024, as a result of the EBITDA loss, the FP measurement resulted in no MICP payout because results were below the threshold. For 2025, there was no MICP program. The Compensation Committee retains discretion to adjust the calculation of the two measures for changes outside normal business operations such as acquisitions or asset sales.

**Long-Term Equity Incentives.** The Compensation Committee approves grants under the Data I/O Corporation 2023 Omnibus Incentive Compensation Plan (the "2023 Plan") formerly under the Data I/O Corporation 2000 Stock Compensation Incentive Plan (the "2000 Plan"). The 2023 Plan is Data I/O's only long-term employee equity incentive plan. The primary purpose of the 2023 Plan is to make a significant element of executive pay a reward for taking actions which maximize shareholder value over time. Generally, new option, restricted stock unit and/or performance stock unit awards are granted under the 2023 Plan. New options or stock awards may also be granted to the Board of Directors under the 2023 Plan. When the 2023 Plan was approved, all shares remaining in the 2000 Plan were transferred to the 2023 Plan, and future awards will be made under the 2023 Plan.

Starting in 2023, under the provisions of the 2023 Plan, a portion of the equity awards to executives were Performance Stock Units ("PSU") (roughly 20% based on achieving the target level performance) and 80% Restricted Stock Units ("RSU"). The performance measures for the 2023 PSUs awarded are revenue growth targets for the three-year period ending December 31, 2025. Achieving a threshold growth measure earns 50% of the PSU target award; achieving the target growth measure earns 100% of the PSU target award; and achieving the maximum target growth measure earns 150% of the PSU target award.

In 2025, there were no equity awards for existing executives. In 2024, equity awards for existing executives were 50% RSUs and 50% PSUs. The performance measures for the executives' PSUs were 50% based on revenue targets for the three-year period ending December 31, 2026, and 50% based on EBITDA targets for the three-year period December 31, 2026. Each measure with a threshold, target and maximum target.

<u>Award Criteria</u>

The Compensation Committee grants options, RSU and/or PSU awards based primarily on its perception of the executive's ability to affect future shareholder value and secondarily on the competitive conditions in the market for highly-qualified executives who typically command compensation packages which include a significant equity incentive. All RSU and PSU awards granted to our executive officers in 2025 and 2024 were based on these criteria.

<u>Exercise Price</u>

Historically, all options granted by Data I/O have been granted with an exercise price equal to the fair market value (an average of the day's high and low selling price) of Data I/O's Common Stock on the date of grant and, accordingly, will only have value if Data I/O's stock price increases. Options granted to employees in 2025 are non-qualified.

<u>Vesting and Exercise</u>

Options granted to employees generally vest quarterly over four years at a rate of 6.25% per quarter and have a six-year term. The current primary form of equity compensation has been restricted stock unit grants. For 2023, RSU grants to executives vest annually over a three- or four-year period. All the 2023 PSU awards vest upon the three-year performance achievement on December 31, 2025. For 2024, RSU grants to executives vest annually over a three-year period. There were no RSU grants in 2025 to executives, excluding the RSU inducement grant to Mr. DiBona in August 2025. All the 2024 PSU awards vest upon achievement of the two possible three-year performance measures on December 31, 2026. There were no PSU awards in 2025. RSU grants to non-employee Directors vest in one year or on the date of the next Annual Meeting of Shareholders, if earlier. All grants are subject to possible acceleration of vesting in connection with certain events leading to a change in control of Data I/O or in the event in a change in control or at any other time at the discretion of the Compensation Committee. All options granted to executive officers are issued in tandem with limited stock appreciation rights ("SARs"), which become exercisable only in the event of a change in control of Data I/O. See: "Change in Control and other Termination Arrangements."

<u>Award Process</u>

The timing of our typical grant/award is usually determined well in advance, with approval at a scheduled meeting of our Board of Directors or its Compensation Committee with the grant date generally to be effective on the date of our next Annual Meeting of Shareholders or, for employees, the first day of the following month. (June 1<sup>st</sup> for annual refresh grants was selected as no typically planned public releases coincide with or around this date.) The Annual Meeting of Shareholders does not coincide with any of our scheduled earning releases. We do not anticipate option, RSU or PSU awards at other dates, except for grants/awards to new employees based on generally the first of the month following their first date of employment or in specific circumstances approved by the Compensation Committee. The grant/award date is established when the Compensation Committee approves the grant/award and all key terms have been determined. If at the time of any planned grant/award date, any member of our Board of Directors or Executive Officers is aware of material non-public information, the Company would not generally make the planned grant/award. In such an event, as soon as practical after material information is made public, the Compensation Committee would authorize the delayed grant/award.

| **Benefits.** Executive Officers of Data I/O are eligible for the same benefits as other Data I/O employees. Data I/O has no defined benefit pension programs. Data I/O has a 401(k) tax qualified retirement savings plan in which all U.S. based employees, including U.S. Executive Officers are able to contribute the lesser of up to 100% of their annual salary or the limit prescribed by the IRS on a Roth or pre-tax basis. Data I/O's match formula is 100% on the first 2% and 50% on the next 4%, which requires a 6% contribution to receive a 4% matching contribution. In 2025, matching contributions in any year require employment on December 31, except in the case of retirement per the plan, and vest after three years of service credit. In 2026 Data I/O changed the matching contribution schedule from a yearly match to a per pay period match. There is also no longer a requirement to be employed as of December 31 to be eligible for the matching contribution. |
| **Perquisites and Other Personal Benefits.** We believe perquisites are not conditioned upon performance, create divisions among employees, undermine morale, and are generally inconsistent with our compensation philosophy and policy of equitable treatment of all employees based upon their contribution to our business. No executive officer received perquisites valued at $10,000 or more in 2025 or 2024. |
| **Individual Executive Officers' Performance.** The base salary of each executive officer is reviewed annually by the President and Chief Executive Officer. This is done on the basis of a review by the President and Chief Executive Officer, evaluating the executive's prior year performance against their individual job responsibilities and attainment of corporate objectives and Data I/O's financial performance. In developing executive compensation packages to recommend to the Compensation Committee, the President and Chief Executive Officer considers, in addition to each executive's prior year performance, the executive's long-term value to Data I/O, the executive's pay relative to that for comparable surveyed jobs, the executive's experience and ability relative to executives in similar positions, and the current year increases in executive compensation projected in industry surveys. |

---

The Compensation Committee then reviews the President and Chief Executive Officer's recommendations for executive officers' total compensation and approves final decisions on pay for each executive officer based on the President and Chief Executive Officer's summary of the executive officer's performance and on the other criteria and survey data described above. In this process, the Compensation Committee consults with Data I/O's President and Chief Executive Officer.

The base salary, total cash compensation, and long-term equity incentive compensation for the President and CEO are reviewed annually by the Compensation Committee. This review includes a written evaluation of the CEO's performance for the previous year. The Compensation Committee meets annually without the President and Chief Executive Officer to evaluate his performance and to develop a recommendation for his compensation for the coming year. In addition to reviewing Data I/O's financial performance for the prior year, the Committee reviewed compensation surveys for chief executive officers and the President and Chief Executive Officer's individual performance, including development and execution of short-term and long-term strategic objectives, Data I/O revenue growth and profitability, the achievement of which is expected to increase shareholder value.

The Compensation Committee determined the compensation package, including salary, bonus, MICP participation, PSU awards, RSU awards, and other benefits for Mr. Wentworth, President and Chief Executive Officer, based on the Committee's perception of his qualifications for the position and his ability to affect future shareholder value, results delivered, compensation surveys and the competitive conditions in the market.

***Consideration of Risk in Compensation***

The Compensation Committee believes that promoting the creation of long-term value discourages behavior that leads to excessive risk. The Compensation Committee believes that the following features of our compensation programs provide incentives for the creation of long-term shareholder value and encourage high achievement by our executive officers without encouraging inappropriate or unnecessary risks:

· Our long-term incentives in the form of stock options, RSU, and/or PSU awards are at the discretion of the Compensation Committee and not formulaic.

· Stock options become exercisable over a four-year period and remain exercisable for up to six years from the date of grant, RSU awards vest over a three- or four-year period, and PSU awards vest based on achievement over a three-year performance period, encouraging executives to look to long-term appreciation in equity values.

· We balance short and long-term decision-making with the annual cash incentive program and equity in the form of stock options, RSU, and/or PSU that vest over three- or four-years.

· The metrics used in the MICP measure are set by the Compensation Committee, which believes it will drive shareholder value. Moreover, the Committee attempts to set ranges for these measures that encourage success without encouraging excessive risk-taking to achieve short-term results. The PSU measures which are cumulative over time further balance longer-term with short-term outcomes.

· In addition, the overall MICP incentive compensation cannot exceed two times the MICP Target amount, no matter how much performance exceeds the measures established for the year.

***Accounting and Tax Considerations of our Compensation Program***

Options granted to employees are non-qualified options, when awarded, because of the more favorable tax treatment for Data I/O. We are required to value granted stock options under the fair value method and expense those amounts in the income statement over the stock option's remaining vesting period. Restricted stock is valued at its fair value on the award date and is expensed over its vesting period.

We have structured our compensation program in the past to comply with Internal Revenue Code Sections 162(m) and 409A. Under Section 162(m) of the Internal Revenue Code, a limitation was placed on tax deductions of any publicly-held corporation for individual compensation to covered employees (generally the chief executive officer and the three other most highly compensated executive officers, other than the chief financial officer, whose compensation must be disclosed pursuant to rules and regulations under the Securities Exchange Act of 1934) exceeding $1 million in any taxable year. The Compensation Committee is aware of this limitation and believes that no compensation paid in 2024 or 2025, or expected to be paid in 2026, by Data I/O will exceed the $1 million limitation of Section 162(m) except possibly related to a change of control. The Section 162(m) treatment will continue to be part of future compensation considerations.

***Clawback of Executive Compensation***

The Board of Directors believes that it is in the best interests of the Company and its shareholders to create and maintain a culture that emphasizes integrity and accountability and that reinforces the Company's compensation philosophy. On October 25, 2023, the Board adopted an Incentive Compensation Recovery Policy ("Clawback Policy") which provides for the recovery of erroneously awarded incentive compensation in the event that the Company is required to prepare an accounting restatement due to material noncompliance of the Company with any financial reporting requirements under the federal securities laws. This Clawback Policy is designed to comply with Section 10D of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), related rules and the listing standards of the Nasdaq Stock Market or any other securities exchange on which the Company's shares are listed in the future.

***Change in Control and other Termination Arrangements***

---

| | |
|:---|:---|
| ·  | **Change in Control Arrangements**. Data I/O has entered into agreements with Mr. Wentworth and Mr. DiBona (the "Executive Employment Agreement"), which entitle them to receive payments if they are terminated without cause or resign with good reason within specified periods before or after the occurrence of certain events deemed to involve a change in control of Data I/O. The Executive Employment Agreement ensure appropriate incentives are in place for Messrs. Wentworth and DiBona to complete any change in control related transaction and transition, as well as comply with the provisions of Section 409A of the Internal Revenue Code. The Executive Agreement states that the resulting additional severance will be calculated under the Executive Agreement based on Data I/O's standard severance arrangements in place immediately preceding the date of a change in control (See: "Other Termination Arrangements" below for current severance policy). The Executive Employment Agreement provide for continuation and vesting in Data I/O's matching 401(k) contributions through the date of termination after a change in control and include a reimbursement allowance of $20,000 for outplacement services. The Mr. DiBona's Executive Employment Agreement has a transaction closing incentive of one-half year's annual salary for Mr. DiBona to encourage the consideration of all forms of strategic alternatives. |
|  | Data I/O's 2025 RSU awards have been granted pursuant to the provisions of the 2023 Plan. Prior year's awards were under either the 2023 Plan or the 2000 Plan. The Change in Control provision applicable to the 2000 Plan and the 2023 Plan are as follows:<br>2000 Plan<br>The 2000 Plan allows for the granting of "Awards", which include options, restricted stock and other awards made pursuant to the 2000 Plan. Subject to any different terms set forth in the award agreement, vesting of "qualifying" options and restricted stock awards may be affected by a Change in Control as described out in the table below. A "Change in Control" is defined to include (i) a merger or consolidation of the Company in which more than 50% of the voting power of the Company's outstanding stock after the transaction is owned by persons who are not shareholders immediately prior to such transaction, and (ii) the sale or transfer of all or substantially all of the Company's assets. A "Qualifying Award' is defined as an option or other Award that has been held for at least 180 days as of the Change of Control. "Qualifying Shares" means common stock issued pursuant to a Qualifying Award which are subject to the right of Data I/O to repurchase some or all of such shares at the original purchase price (if any) upon the holder's termination of services to Data I/O.<br>2023 Plan<br>The 2023 Omnibus Incentive Compensation Plan ("2023 Plan") replaced the 2000 Plan going forward for new awards, and was approved by the shareholders at the 2023 Annual Meeting. The 2023 Plan has substantially similar treatment of an award as the amended 2000 Plan in the event of a Change in Control. |

| | |
|:---|:---|
| **Treatment of Awards on a Change in Control** | **Acceleration of Vesting** |
| The outstanding Awards do not remain outstanding or are not assumed by the surviving entity or replaced with comparable Awards. | Subject to certain limitations, the vesting of Qualifying Awards is accelerated in full. Restricted stock will vest and options will be exercisable in full prior to the effective date of the Change of Control.  |
| The outstanding Awards remain outstanding after a Change of Control or are assumed by the surviving entity or replaced with comparable Awards. | Subject to certain limitations, the vesting of outstanding Qualifying Awards will be accelerated to the extent of 25% of the unvested portion thereof. The remaining 75% of the unvested portion will vest in accordance with the vesting schedule set forth in the applicable Award agreement.  |
| The outstanding Awards remain outstanding after a Change of Control or are assumed by the surviving entity or replaced with comparable Awards, but the holder of a Qualifying Award is terminated involuntarily within one year of the Change of Control. | All Awards held by such person will be accelerated in full. Restricted stock will vest and options will be exercisable in full for a period of 90 days commencing on the effective date of the involuntary termination, or if shorter, the remaining term of the option.  |

|  | In 1983, Data I/O adopted a SAR Plan which allows the Board of Directors to grant to each director, executive officer or holder of 10% or more of the stock of Data I/O a SAR with respect to certain options granted to these parties. A SAR has been granted in tandem with each option granted to an executive officer of Data I/O. SARs granted which have been held for at least six months are exercisable for a period of 20 days following the occurrence of either of the following events: (i) the close of business on the day that a tender or exchange offer by any person (with certain exceptions) is first published or sent or given if, upon consummation thereof, such person would be the beneficial owner of 30% or more of the shares of Common Stock then outstanding; or (ii) approval by the shareholders of Data I/O (or, if later, approval by the shareholders of a third party) of any merger, consolidation, reorganization or other transaction providing for the conversion or exchange of more than 50% of the outstanding shares of Data I/O's Common Stock into securities of a third party, or cash, or property, or a combination of any of the foregoing. Currently, only one option grant remains outstanding that includes a SAR. |
| ·  | **Other Termination Arrangements.** Data I/O has a severance policy for U.S. employees that provides for severance payouts for terminations without cause based upon years of service. The current formula, effective March 1, 2014, is 1 week pay for each year of service with a limit of four months' pay. Mr. Wentworth and Mr. DiBona had at April 13, 2026, approximately 1.6 and .67 years of service, respectively. Mr. Wentworth is entitled to a one year of base salary severance, except in the case of a change in control, as part of his employment agreement. Mr. DiBona is entitled to a one-half year of base salary severance, except in the case of a change in control, as part of his employment arrangement. Data I/O does not have a formal policy regarding executive severance but has generally provided an amount it believes is consistent with severance typically provided for executives in similar positions and with similar periods of service. |

**Policy on Pre-Approval by Audit Committee of Services Performed by Independent Auditors**

The Audit Committee's policy is to pre-approve all audit and permissible non-audit services provided by the independent auditors. These services may include audit services, non-audit services, tax services and other services. Pre-approval is detailed as to the particular service or category of service and is subject to a specific engagement authorization.

During the year, circumstances may arise when it may become necessary to engage the independent auditors for additional services not contemplated in the original pre-approval. In those circumstances, the Audit Committee has delegated pre-approval authority to the Chair of the Audit Committee for those instances when pre-approval is needed prior to a scheduled Audit Committee meeting. These additional approvals should be reported at the next scheduled Audit Committee meeting.

For 2025, all services provided by the independent auditors were pre-approved.
