**PART I**

<u>**Item 1. Business**</u>

This Annual Report on Form 10-K and the documents incorporated herein by reference contain forward-looking statements based on current expectations, estimates and projections about Data I/O Corporation's industry, management's beliefs and certain assumptions made by management. See "Management's Discussion and Analysis of Financial Condition and Results of Operations – Forward Looking Statements."

***General***

Data I/O Corporation ("Data I/O", "We", "Our", "Us") is a global market leader for advanced programming, security deployment, security provisioning and associated Intellectual Property ("IP") protection and management solutions used in electronics manufacturing with flash memory, microcontrollers, and flash memory-based intelligent devices as well as secure element devices, authentication devices and secure microcontrollers. We collectively refer to IP protection, security provisioning of devices, provisioning of security into devices, and related services such as cloud onboarding and device and provisioning documentation management as "security deployment". Data I/O designs, manufactures and sells programming and security deployment systems and services for electronic device manufacturers, specifically targeting high-growth areas such as high-volume users of flash memory and flash memory-based microcontrollers.

Our mission is to bring the world's electronic devices to life. Programmable devices are used in products such as automobile electronics, smartphones, HDTVs, smart meters, gaming systems and a broad category called Internet of Things ("IoT"). Our solutions, some of which include security deployment and process control capabilities, enable us to address the demanding requirements of the electronic device market, where applications security and IP protection are essential to our customer's success.

Data I/O was incorporated in the State of Washington in 1969 and its business was founded in 1972. Our website address is www.dataio.com.

***Major Impacts on 2025***

The year ended December 31, 2025 was defined by the Company's strategic transformation, directed by President and CEO William Wentworth, who assumed the role in the fourth quarter of 2024. The Company's strategic plan was designed around six priorities: modernizing our go-to-market strategy, investing in our core technology platform, strengthening customer relationships, optimizing business operations and IT infrastructure, improving operational processes, and deploying artificial intelligence across the organization. As we enter 2026, management believes the transformation is approximately one year ahead of the original execution timeline projected by management and that the Company believes it is well positioned to return to revenue growth and a path to positive operating cash flow.

A central element of the strategy was the rapid refresh of the Company's core technology platform, initiated and completed through the course of 2025. The Company launched the next-generation LumenX2 programming platform and LumenX2-M4 manual programmer at the productronica 2025 tradeshow in Munich, Germany in November 2025. The LumenX2 platform, with higher pin counts and increased power, significantly expands the breadth of device technologies supported on the LumenX architecture, including microcontrollers, eMMC, UFS, SPI NOR flash, Secure Elements, and other device types. The LumenX2-M4 features VerifyBoost technology delivering verify speeds of up to 750 megabytes per second. The LumenX2 platform received the 2025 Global Technology Award in the Programming category, and the refreshed LumenX-M8 manual programmer received both the 2025 Mexico Technology Award and the 2025 Step-by-Step Excellence Award. These products support the Company's Unified Programming Platform strategy, which provides a single, scalable programming architecture from design and new product introduction through high-volume production, creating a seamless transition across the preprogrammed parts supply chain.

With the updated programming platform, the Company has turned its 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 now focusing its efforts on progressing toward 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, consumable adapters and services revenue represented approximately 58% of total revenue, helping to moderate the impact of continued softness in capital equipment demand. This diversification is expected to continue as the Company expands its addressable market from traditional programming capex into the broader data provisioning ecosystem.

During 2025, the Company underwent a significant transition in its financial leadership. Gerald Ng, who had served as Vice President, Chief Financial Officer, Secretary and Treasurer since August 2023, departed the Company in July 2025. Todd Henne served as interim CFO during the transition period. Effective August 11, 2025, the Company appointed Charles DiBona as Vice President of Finance, and as an Executive Officer of the Company and the Company's Vice President, Chief Financial Officer, Secretary and Treasurer, effective August 15, 2025. Mr. DiBona brings extensive experience in financial leadership across public and private companies, including prior roles at Microsoft Corporation, Unify Square, Inc., and LabVantage Solutions, Inc. The leadership transition was part of a broader deliberate strengthening of the executive suite to ensure the Company has the right team in place to execute its growth strategy.

On August 16, 2025, the Company experienced a ransomware incident affecting certain internal IT systems. Upon discovery, the Company promptly activated its response protocols, secured its global IT systems and implemented containment measures, including proactively taking certain platforms offline. The Company engaged leading cybersecurity experts to support system recovery and conduct a comprehensive investigation. It was determined that the attack was not specifically targeted at Data I/O but originated through a vulnerability in a commercially available third-party firewall service provider. By September 2025, the incident had been completely contained and remediated, all global systems were restored, and the Company does not believe it has any remaining risk exposure from the incident. The remediation and associated professional fees resulted in approximately $388,000 of one-time costs, primarily recorded in the third quarter of 2025. As an outcome of the incident, the Company's IT systems and cybersecurity posture were strengthened, with improved corporate processes and enhanced security infrastructure.

In the latter part of 2025, the Company began the implementation process of a new enterprise resource planning ("ERP") system, Acumatica, to replace the legacy IFS system. This initiative is part of the broader effort to optimize business operations and IT infrastructure. The Company is leveraging AI-driven tools to accelerate traditionally time-consuming aspects of the ERP implementation, including chart of accounts mapping, data migration planning, and intercompany policy documentation. The ERP transition is expected to improve operational efficiency, enhance financial reporting capabilities, and support the Company's growth objectives. The Acumatica implementation project remains on schedule with a target switchover date of July 1, 2026.

Geopolitical, economic and trade uncertainties continued to impact the Company's markets in 2025. Tariff policies affecting goods manufactured in the United States and China created additional cost pressures and business uncertainty for the Company and its customers. As a company that produces products in both the United States and China and sells into global markets, the evolving tariff environment required ongoing evaluation of manufacturing strategies, supply chain resilience, and pricing. Some customers continued to shift production locations in response to trade tensions, affecting demand patterns. The Company's dual-sourced manufacturing strategy in Redmond, Washington and Shanghai, China provides flexibility to navigate these challenges and optimize tariff exposure and to support customers to the extent they shift manufacturing to the Americas. While oil price increases and conflicts in the Middle East have limited direct effect on our input factors, their broader impacts on general price levels and economic activity could affect our customers and end markets as well as our material, labor, and shipping costs.

The broader semiconductor market has experienced a multi-year cyclical downturn continuing into 2025, with notable softness in automotive electronics, historically the Company's largest end market, as a reassessment of electric vehicle capacity and manufacturing plans affecting customer ordering patterns. Automotive electronics represented approximately 64% of 2025 bookings, compared to 59% in 2024. Demand for capital equipment was further impacted by a reallocation of technology spending, with AI and AI datacenter-related investments taking priority. In response, the Company has shifted its strategic focus to diversify its market reach, expanding into the broader data provisioning market and positioning to capitalize on the emerging buildout of Edge AI. The shift toward servicing the overall data provisioning market represents a significantly larger opportunity than the traditional programming equipment market. Early evidence of customer alignment and interest in this expanded value proposition was encouraging in the fourth quarter 2025 and into early 2026.

During 2025, the Company deployed artificial intelligence internally across all functional departments to accelerate operations and reduce costs. AI-enabled efficiencies contributed to a 7% reduction in normalized operating expense run-rate, from an annualized $26.7 million at the time of the CEO transition in November 2024 to $24.8 million by year end 2025, with plans for at least an additional $1 million of annual run rate savings 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 processes, legal documentation, and internal business operations. These capabilities enabled the Company to accomplish its transformation objectives faster than originally planned.

Additionally, in January 2026, the Company filed a shelf registration statement on Form S-3 providing the ability to issue up to $20 million dollars of equity securities, providing financial flexibility for potential strategic initiatives, including acquisitions aligned with the Company's growth strategy. The Company also engaged a leading boutique middle-market investment bank during 2025 to support inorganic growth initiatives.

Subsequent to year end, in February 2026, the Company announced a collaboration with IAR, a leader in embedded development tools and security solutions, to combine IAR's security expertise with Data I/O's provisioning expertise to create a frictionless solution that reduces the complexity that exists with current device provisioning approaches. This collaboration is intended to simplify the process of securely programming and provisioning devices across global manufacturing supply chains.

***Industry Background***

Data I/O enables companies to improve productivity, increase supply-chain security and reduce costs by providing device data programming and security deployment solutions that allow our customers to take IP (large design and data files) and protect and program it into memory, microcontroller, security and logic devices quickly and cost-effectively. We also provide services related to hardware support, system and repair, and device programming. Companies that design and manufacture products utilizing programmable electronic devices, ranging from automobiles to industrial controls to edge AI, purchase programming solutions from us. Trends of increasing device densities, shrinking device packages, increased demands for security, and customers increasing their software content file sizes, combined with the increasing numbers of intelligent devices such as automotive electronics and IoT applications, are driving demand for our solutions.

Geopolitical, economic and trade uncertainties continued to impact the Company's markets in 2025. Tariff policies created additional cost pressures and business uncertainty in the market with some players shifting production locations in response to trade tensions and thereby affecting demand patterns.

In line with the multi-year cyclical downturn in the broader semiconductor market, automotive electronics, historically the Company's largest end market, has exhibited notable weakness continuing into 2025 as a reassessment of electric vehicle capacity and manufacturing plans affected customer ordering patterns. Automotive electronics represented approximately 64% of 2025 bookings, compared to 59% in 2024. More generally, overall capital equipment spending has seen a reallocation of technology spending towards AI and AI datacenter-related investments. Responding to and taking advantage of these long-term trends, the Company has shifted its strategic focus towards expanding into the greater data provisioning market and positioning to capitalize on the nascent buildout of Edge AI. Semiconductors in general, but especially within the emerging Edge AI sector, have exhibited an increasing need for security provisioning.

The data provisioning market has also continued to diversify such that adjacent segments such as programming services and programming at test now exceed the company's traditional market segment of capital equipment.

**Products**

To accommodate the expanding variety and quantities of programmable devices being manufactured today, we offer multiple solutions for the numerous types of device mix and volume usage by our customers in the various market segments and applications. We work closely with leading manufacturers of programmable devices to develop our products to meet the requirements of a particular device and invested in 2025 in updating our programming platform to meet customers' evolving needs.

The Company launched the next-generation LumenX2 programming platform and LumenX2-M4 manual programmer at the productronica 2025 tradeshow in Munich, Germany in November 2025. The LumenX2 platform, with higher pin counts and increased power, significantly expands the breadth of device technologies supported on the LumenX architecture, including microcontrollers, eMMC, UFS, SPI NOR flash, Secure Elements, and other device types. The LumenX2-M4 features VerifyBoost technology delivering verify speeds of up to 750 megabytes per second. The platform received the 2025 Global Technology Award in the Programming category, and the refreshed LumenX-M8 manual programmer received both the 2025 Mexico Technology Award and the 2025 Step-by-Step Excellence Award. These products support the Company's Unified Programming Platform strategy, which provides a single, scalable programming architecture from design and new product introduction through high-volume production, creating a seamless transition across the preprogrammed parts supply chain.

Our automated systems have list selling prices ranging from approximately $150,000 to $210,000 and our manual systems have list selling prices ranging from approximately $8,000 to $11,000.

Net sales in the U.S. for 2025, 2024 and 2023 were (in millions) $1.3, $1.4, and $2.8, respectively. Some of our customers' orders delivered internationally are heavily influenced by U.S. sales-based efforts.

**<u>International Sales</u>**

International sales represented approximately 94%, 94%, and 90% of net sales in 2025, 2024 and 2023, respectively. We make foreign sales through our wholly-owned subsidiaries in Germany and China, as well as through independent distributors and sales representatives operating in 39 countries. Our independent foreign distributors purchase our products for resale and we generally recognize the sale at the time of shipment to the distributor. As with U.S. sales representatives, sales made by international sales representatives are on an agency basis, with sales made directly to the customer by us.

Net international sales for 2025, 2024 and 2023 were (in millions) $20.2, $20.4, and $25.3, respectively. We determine international sales by the international geographic destination into which the products are sold and delivered and include not only sales by foreign subsidiaries but also export sales from the U.S. to our foreign distributors and to our representatives' customers. International sales do not include transfers between Data I/O and our foreign subsidiaries. Export sales are subject to U.S. Department of Commerce regulations. We have not, however, experienced difficulties to date as a result of these requirements. Our products typically do not require export licenses. We have not made sales to Iran or any Iranian governmental entities or any other blacklisted companies or countries.

Fluctuating exchange rates and other factors beyond our control, such as the coronavirus, international monetary stability, tariff and trade policies and U.S. and foreign tax and economic policies, may affect the level and profitability of international sales. We cannot predict the effect of such factors on our business, but we try to consider and respond to changes in these factors, particularly as the majority of our costs are U.S. based while the vast majority of our sales are international.

***Competition***

The competition in the programming systems market is fragmented with several companies selling directly competitive solutions. Our direct competition competes primarily based on price. Many of these competitors compete on a regional basis. Although competition in the security deployment market is developing, we expect competition in the market to increase as security deployment becomes more important. There are alternative security deployment solutions such as software-based security, rather than the hardware-based security of our SentriX equipment.

In addition, we compete with multiple substitute forms of device programming including "home grown" solutions. Programming after device placement may be done with In Circuit Test ("ICT"), In System Programming ("ISP"), and End of Line Downloading ("EOL"). Some automotive products may also be programmed over the air ("OTA"). IoT devices may also be programmed with ICT, ISP, EOL or OTA. In addition, new security devices may be required to be programmed using device-specific programmers developed by the semiconductor manufacturer.

While we are not aware of any published industry market reports covering the programming systems or security deployment market, according to our internal analysis of competitors' revenues, we believe we continue to be one of the largest suppliers in the programming systems market.

***Manufacturing, Raw Materials and Backlog***

We strive to manufacture and provide the best solutions for advanced programming. We primarily assemble and test our products at our principal facilities in Redmond, Washington and Shanghai, China. Both of these locations are ISO 9001:2015 certified. We outsource our circuit board manufacturing and fabrication. As a resilient supply chain strategy, we manufacture various products in both of our production facilities. This strategy allows opportunity to mitigate some of the risks of having only one location, as well as enabling tariff and tax optimization strategies. We use a combination of standard components and fabricated parts manufactured to our specifications. Most components used are available from a number of different suppliers and subcontractors but certain items, such as some handler and programmer and security deployment subassemblies, custom integrated circuits, hybrid circuits and connectors, are purchased from single sources. We believe that additional sources can be developed for most present single-source components without significant difficulties. Single-source components may not always continue to be readily available or may be subject to part shortage delays. If we cannot develop alternative sources for these components, or if we experience deterioration in relationships with these suppliers, there may be price increases, minimum order quantities, end of life purchase requirements, costs associated with integrating alternatively sourced parts, and delays or reductions in product introductions or shipments, which may materially adversely affect our operating results.

In accordance with industry practices, generally all orders are subject to cancellation prior to shipment without penalty, except for contracts calling for custom configuration. To date, such cancellations have not had a material effect on our sales volume. To meet customers' delivery requirements, we manufacture certain products based upon a combination of backlog and anticipated orders. Most orders are scheduled for delivery within 1 to 90 days after receipt of the order.

Our backlog of pending orders was approximately (in millions) $1.6, $3.5, and $2.8 as of December 31, 2025, 2024 and 2023, respectively. The size of backlog at any date is not necessarily a meaningful indicator of the trend of our business.

***Research and Development***

We believe that continued investment in research and development is critical to our future success. We continue to develop new technologies and products and enhance existing products. Future growth is largely dependent upon the timely development and introduction of new products, as well as the development of technology and algorithms to support the latest programmable devices. Where possible, we may pursue partnerships and other strategic relationships to add new products, capabilities and services, particularly in security deployment. We are currently focusing our research and development efforts on strategic growth markets, including automotive electronics, IoT and security deployment. We are continuing to develop technology for manual and automated systems to program new categories of semiconductors, including Secure Elements, TPMs, Authentication Chips, and Secure Microcontrollers. We plan to deliver new programming technology, automated handling systems, factory automation communications software, and enhancements for security deployment in the manufacturing environment. We also continue to focus on increasing our capacity and responsiveness for new device support requests from customers and programmable integrated circuit manufacturers by revising and enhancing our internal processes and tools. Our research and development efforts have resulted in the release of significant new products and product enhancements over the past several years.

During 2025, the Company's R&D efforts focused on the development and launch of the next-generation LumenX2 programming platform and LumenX2-M4 manual programmer, which were introduced at the productronica 2025 tradeshow in November 2025. The LumenX2 programming platform, with higher pin counts and increased power, significantly expands the breadth of device technologies supported, including microcontrollers, eMMC, UFS, SPI NOR flash, Secure Elements, and other device types. The R&D team has begun the systematic integration of artificial intelligence tools to accelerate programming algorithm development and device support.

During 2025, 2024 and 2023, we made expenditures for research and development of (in millions) $6.5, $6.2 and $6.5, respectively, representing 30%, 29% and 23% of net sales, respectively. Research and development costs are generally expensed as incurred.

***Finance and Administration***

The Company began the implementation process of a new enterprise resource planning system, Acumatica, to replace the legacy IFS system. This initiative is part of the broader effort to optimize business operations and IT infrastructure. The Company is leveraging AI-driven tools to accelerate traditionally time-consuming aspects of the ERP implementation, including chart of accounts mapping, data migration planning, and intercompany policy documentation. The ERP transition is expected to improve operational efficiency, enhance financial reporting capabilities, and support the Company's growth objectives. The Acumatica implementation project remains on schedule with a target switchover date of July 1, 2026.

During 2025, the Company deployed artificial intelligence internally across all functional departments to accelerate operations and reduce costs. AI tools were applied to software engineering to accelerate programming algorithm development and device support, ERP implementation planning and data migration, customer support processes, legal documentation, and internal business operations. These capabilities enabled the Company to accomplish its transformation objectives faster than originally planned.

On August 16, 2025, the Company experienced a ransomware incident affecting certain internal IT systems. Upon discovery, the Company promptly activated its response protocols, secured its global IT systems and implemented containment measures, including proactively taking certain platforms offline. The Company engaged leading cybersecurity experts to support system recovery and conduct a comprehensive investigation. It was determined that the attack was not specifically targeted at Data I/O but originated through a vulnerability in a commercially available third-party firewall service provider. By September 2025, the incident had been completely contained and remediated, all global systems were restored, and the Company does not believe it has any remaining risk exposure from the incident. The remediation and associated professional fees resulted in approximately $388,000 of one-time costs, primarily recorded in the third quarter. As an outcome of the incident, the Company's IT systems and cybersecurity posture were strengthened, with improved corporate processes and enhanced security infrastructure.

***Patents, Copyrights, Trademarks and Licenses***

We rely on a combination of patents, copyrights, trade secrets and trademarks to protect our IP, as well as product development and marketing skills to establish and protect our market position and will continue to apply for and add new patents to our patent portfolio as we develop strategic new technologies.

We attempt to protect our rights in proprietary systems (architecture, implementations, software) including Lumen®X, FlashCORE, TaskLink, ConneX, SentriX and other software products, by retaining the title to and copyright of the software and documentation, by including appropriate contractual restrictions on use and disclosure in our licenses, and by requiring our employees to execute non-disclosure agreements. Our software products are not typically sold or licensed separately from sales of programming systems. However, 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.

Because of the rapidly changing technology in the semiconductor, electronic equipment and software industries, portions of our products might infringe upon existing patents or copyrights, and we may be required to obtain licenses or discontinue the use of infringing technology. We believe that any exposure we may have regarding possible infringement claims is a reasonable business risk similar to that assumed by other companies in the electronic equipment and software industries. However, any claim of infringement, with or without merit, could be costly and a diversion of management's attention, and be an adverse determination could adversely affect our reputation, potentially preclude us from offering certain products, and subject us to substantial liability. As of December 31, 2025, we were not subject to any pending actions regarding infringement claims.

***Employees - Human Capital***

As of December 31, 2025, we had a total of 97 employees, of which 44 were located outside the U.S. and 7 of which were part time. We also utilize independent contractors for specialty work, primarily in research and development, and utilize temporary workers to adjust capacity to fluctuating demand and for special projects. Many of our employees are highly skilled, trained and experienced in specialized areas and our continued success will depend in part upon our ability to attract and retain employees who can be in great demand within the industry. None of our employees are represented by a collective bargaining unit and we believe relations with our employees are favorable. In foreign countries we have employment agreements or, in China, the Shanghai Foreign Services Co., Ltd. ("FSCO") labor agreement. Because of the creation of specialized knowledge and skills in our business, there are extra short-term challenges to hiring and training replacements. Our hiring and retention strategies and efforts include emphasis on the advantages of working in a technology oriented, smaller, international, public company, and the culture of our organization. We utilize competitive pay practices, incentive compensation, equity awards, and benefits such as health care, life and disability insurance, paid time off, education and volunteer time.

Through the course of 2025 and early 2026, the Company has undertaken organizational changes to centralize the direction and management of business functions in its Redmond, Washington headquarters. The Company believes that this structure will enable a more consistent strategic focus, especially as the Company seeks to expand into adjacent segments of the data provisioning market and generally extend market reach.

***Environmental, Social and Governance ("ESG")***

Data I/O is committed to the responsibilities associated with modern age ESG. The Company's key pillars for ESG support a framework for sustainable growth and include Leadership & Governance, Environment, Innovation, Human Capital, Social Capital, and Financial Excellence. Initiatives within these areas apply to the Company's daily global operations as well as within its supply chains. Our facilities are subject to numerous laws and regulations concerning the discharge of materials or otherwise relating to the environment. In addition to this commitment, the Company has a track record of meeting its ESG regulatory obligations, being a solid corporate citizen, delivering superior value to its customers and partners, and demonstrating corporate stewardship including returning capital to shareholders through past share buybacks.

**Item 1A. Risk Factors**

**Cautionary Factors That May Affect Future Results**

Our disclosure and analysis in this Annual Report contains some forward-looking statements. Forward-looking statements include our current expectations or forecasts of future events. The reader can identify these statements by the fact that they do not relate strictly to historical or current facts. In particular, these include statements relating to future action, supply chain expectations, semiconductor chip availability, Russia-Ukraine war impacts, prospective products, expected market growth, new technologies and trends, industry partnerships, foreign operations, economic expectations, future performance or results of current and anticipated products, sales efforts, expenses, outcome of contingencies, impact of regulatory requirements, tariffs and financial results.

Any or all of the forward-looking statements in this Annual Report or in any other public statement made may turn out to be wrong. They can be affected by inaccurate assumptions we might make or known or unknown risks and uncertainties can affect these forward-looking statements. Many factors – for example, product competition and product development – will be important in determining future results. Moreover, neither Data I/O nor anyone else assumes responsibility for the accuracy and completeness of these forward-looking statements. Actual future results may materially vary.

We undertake no obligation to publicly update any forward-looking statements after the date of this Annual Report, whether as a result of new information, future events or otherwise. The reader should not unduly rely on our forward-looking statements. The reader is advised, however, to consult any future disclosures we make on related subjects in our 10-Q, 8-K and 10-K reports to the Securities and Exchange Commission ("SEC") and press releases. Also, note that we provide the following cautionary discussion of risks, uncertainties and possible inaccurate assumptions relevant to our business. These are factors that we think could cause our actual results to differ materially from expected and historical results. Other factors besides those listed here could also adversely affect us. This discussion is permitted by the Private Securities Litigation Reform Act of 1995.

**RISK FACTORS:**

**TARIFFS AND TRADE ISSUES**

***Changes in tariffs and*** ***issues of*** ***trade*** ***and global conflict******may adversely affect our business, including revenues and/or gross margins.***

The tariff environment continued to evolve in 2025, with new tariff actions and ongoing trade tensions between the United States and China among others affecting the Company's costs and competitive position. The Company produces products in both the United States and China and sells into global markets. 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. The Company's dual-sourced manufacturing strategy in Redmond, Washington and Shanghai, China provided flexibility to navigate tariff challenges, optimize tariff exposure and support customers to the extent they shift manufacturing to the Americas. However, further increases in tariff rates, additional items subject to tariffs, or retaliatory trade actions could increase costs and adversely affect revenues and gross margins and on-going uncertainty surrounding tariffs may continue to affect customer investment decisions and timelines, adversely affect demand for the Company's offerings.

We produce products in the United States and China. Currently, certain of our products are subject to tariffs imposed by one country on goods manufactured in the other country. There is uncertainty regarding the tariffs expected to be imposed, and any increase in tariff rates and subjecting additional items to tariffs could increase our costs, revenues and the competitiveness of our products due to our manufacturing locations. Trade and tariff issues are creating business uncertainty and may spread to and impact other jurisdictions.

Additionally, ongoing trade tensions between the United States and China are impacting our ability to seamlessly design, build, market and sell our products. These tensions may increase suddenly at any time due to government policies or actions. Some customers have moved production away from China, further from our facilities and engineers. We endeavor to have multi-sourced manufacturing, but this is not currently practical for all products in all locations.

War based restrictions, embargos, and supply chain disruptions have and are occurring because of the Russian invasion of Ukraine, which could have economic and other indirect impacts to our business. We do not have any operations in Russia or Ukraine, nor do we rely on any software or hardware components sourced from these two countries. The escalation of military conflict involving Iran and other actors in the Middle East, including risks of broader regional war, cyberattacks, and disruption to critical shipping routes and energy infrastructure, could materially impact global economic conditions and adversely affect our business, including through increased costs, supply chain disruptions, and demand volatility.

**NEW PRODUCTS OR SERVICES**

***We are pursuing new product or service initiatives, and business models that may develop more slowly and/or to a lesser extent than expected.***

In order to lead in new and potentially lucrative market opportunities, we are making significant investments in people, technology and business development while the market is developing and uncertain. Due to the length of time to market from design to production in security provisioning, if these markets develop more slowly than planned, or if our solutions are not widely accepted, then we may not achieve our expected return on investment in new technologies, which may significantly affect the results of our existing business.

***Failure to adapt to new technological trends in our industry may impact our competitiveness and financial results.***

Product and service technology in our industry evolves rapidly, making timely product innovation essential to success in the marketplace. Introducing products and services with improved technologies or features may render our existing products obsolete and unmarketable. Technological advances and trends that may negatively impact our business include:

---

| |
|:---|
| new device package types, densities, chip interfaces and technologies requiring hardware and software changes in order to be programmed by our products, particularly certain segments of the high-density flash memory markets where after placement programming is recommended by certain semiconductor manufacturers. |
| reduction in semiconductor process geometries for certain 3 Dimensional (3D), Multi Level Cell (MLC) and Triple Level Cell (TLC) NAND and eMMC FLASH memories impact the product data retention through Surface Mount Technology (SMT) reflow or X-ray inspection. Improper SMT process control can negatively impact the end customer's ability to successfully program devices. This can cause them to change their programming methods away from pre-programming to post placement programming techniques, including ISP, ICT. Data I/O has, and continues to work with several semiconductor manufacturers to develop best practices to minimize the impact of reflow and potential concerns about X-ray induced data loss so that preprogramming remains a supported alternative; |
| changes in Flash technology speeds will eventually require us to change the architecture of our programming engines; |
| electronics equipment manufacturing practices, such as widespread use of in-circuit programming or downloading; |
| adoption of proprietary security and programming protocols and additional security capabilities and requirements; |
| customer software platform preferences different from those on which our products operate; |
| customer adoption of newer unsupported semiconductor device technologies such as NVMe memory or device interface methods, particularly if these technologies are adopted by automotive electronics, IoT or wireless customers; and/or |
| more rigid industry standards, which would decrease the value-added element of our products and support services. |

---

If we cannot develop products or services in a timely manner in response to industry changes, or if our products or services do not perform well, our business and financial condition may be adversely affected. Also, our new products or services may contain defects or errors that give rise to product liability claims against us or cause our products to fail to gain market acceptance. Our future success depends on our ability to successfully compete with other technology firms in attracting and retaining key technical personnel.

***Failure to adapt to increasing automotive electronics customer requirements and a rapidly changing global automotive electronics ecosystem may impact our competitiveness and result in a decline in sales or increased costs.***

Concentration in automotive electronics represented approximately 64% of 2025 bookings, compared to 59% in 2024 and 63% in 2023, as the broader slowdown in the semiconductor industry caught up with the automotive sector. Demand was further impacted by a broad-based reallocation of technology spending toward AI-related investments and a reassessment of electric vehicle manufacturing capacity and plans by major automotive OEMs and their supply chains. The emerging buildout of Edge AI represents a potential growth driver as autonomous systems and connected vehicles require increasing volumes of data to be securely provisioned into semiconductor devices at the point of manufacture.

As we have been concentrated on automotive electronics customers, any decrease in demand from these customers may materially impact our results, as it will take some time to transition our product line to other markets. Quality standards and business requirements by our automotive electronics customers, driven in turn by their automotive manufacturer customers, may demand processes and certifications at a higher level than we currently are structured to provide. For example, although we currently meet the ISO 9001:2015 standard, new quality standards, and environmental standards may be demanded by our customers with even more rigorous requirements. In addition, contractual provisions may expose us to greater potential liability and costs and we may be required to provide higher service levels than we currently provide. If we cannot adapt to these industry requirements or manage these contractual provisions, our business may be adversely affected.

We are also seeing a shift in the global automotive industry towards new entrants touting new methods, especially for all electric vehicles. These new entrants may not develop solutions through the traditional value chain. If Data I/O is not able to market and sell effectively to these new entrants, we risk losing market share in our largest market.

***Delays in development, introduction and shipment of new products or services may result in a decline in sales or increased costs.***

We develop new engineering and automated programming systems and services. Significant technological, supplier, manufacturing or other problems may delay the development, introduction or production of these products or services.

For example, we may encounter these problems:

· technical problems in the development of a new programming or provisioning systems;

· inability to hire qualified personnel or turnover in existing personnel or inability to engage or retain key technology partners;

· delays or failures to perform by us or third parties, including some smaller early stage or recently acquired companies, involved in our development projects;

· dependence on large semiconductor companies for cooperation and support to securely provision their devices. These companies must enable us with specific technical information and support Data I/O as a qualified solution to their customers and channel partners;

· delays or failure to develop and utilize Artificial Intelligence ("AI") for our offerings or services, potentially falling behind competitors exploiting the use of AI;

· development of new products or services that are not accepted by the market; and/or

· delays in supply chain for parts needed for new products.

These problems may result in a delay or decline in sales or increased costs.

***We may pursue business acquisitions that could impair our financial position and profitability.***

During 2025, the Company engaged a leading boutique middle-market investment bank to evaluate inorganic growth opportunities. Management has expressed a preference for non-equity funding sources when pursuing acquisitions. The active pursuit of acquisitions increases the risks described below.

We may pursue acquisitions of complementary technologies, product lines or businesses. Acquisitions may include risks, such as:

· burdening management and our operating teams during the integration of the acquisition;

· diverting management's attention from other business concerns;

· failing to successfully integrate, scale or monetize the acquired products or technologies;

· lack of acceptance of the acquired products by our sales channels or customers;

· entering markets where we have no or limited prior experience;

· potential loss of key employees of the acquired company; and/or

· additional burden of support for an acquired programmer architecture.

| *[**Table of Contents**](#toc1)* |

---

Future acquisitions may also affect our financial position. For example, we may use significant cash or incur debt, which would weaken our balance sheet, or issue additional shares, potentially diluting existing shareholders. We may also capitalize goodwill and intangible assets acquired, the amortization or impairment of which would reduce our profitability. We cannot guarantee that future acquisitions will improve our business or operating results.

***If we are unable to protect our IP, we may not be able to compete effectively or operate profitably.***

We rely on patents, copyrights, trade secrets and trademarks to protect our IP, as well as product development and marketing skill to establish and protect our market position. In particular, patents are a key part of our security deployment strategy, and if we are not able to successfully enforce these patents, we might lose our competitive advantage in the security deployment market. We attempt to protect our rights in proprietary software products, including our user interface, product firmware, software module options and other software products by retaining the title to and copyright of the software and documentation, by including appropriate contractual restrictions on use and disclosure in our licenses, and by requiring our employees to execute non-disclosure agreements.

Because of the rapidly changing technology in the semiconductor, electronic equipment and software industries, portions of our products might possibly infringe upon existing patents or copyrights, and we might be required to obtain licenses or discontinue the use of infringing technology. We believe that any exposure we may have regarding possible infringement claims is a reasonable business risk similar to that assumed by other companies in the electronic equipment and software industries. However, any claim of infringement, with or without merit, could be costly and a diversion of management's attention, and an adverse determination could adversely affect our reputation, preclude us from offering certain products, and subject us to substantial liability.

***We might face increased competition and might not be able to compete successfully with current and future competitors.***

Technological advances have reduced the barriers of entry into the capital equipment segment of the data provisioning market in which we compete. We expect competition to increase from both established and emerging companies. If we fail to compete successfully against current and future sources of competition, our profitability and financial performance will be adversely impacted.

The Company is expanding into adjacent segments of the data provisioning market, which has developing competition and may bring exposure to new competitors and competitive forces.

**THIRD PARTY RELATIONSHIPS**

***If we do not develop and enhance our relationships with semiconductor manufacturers, our business may be adversely affected.***

We work closely with most semiconductor manufacturers to ensure that our data programming and security deployment systems comply with their requirements. In addition, many semiconductor manufacturers recommend our managed and secure programming systems for use by users of their programmable devices. These working relationships enable us to keep our programming systems product lines up to date and provide end-users with broad and current programmable device support. As technology changes occur, that could limit the effectiveness of pre-placement programming, particularly for very small high-density NAND, eMMC and UFS devices, certain semiconductor manufacturers may not recommend or may not continue recommending our programming systems for these devices. Our business may be adversely affected if our relationships with semiconductor manufacturers deteriorate or if semiconductor manufacturers are not willing to closely work with us on security deployment. Consolidation within the semiconductor industry may also impact us. As we develop more security deployment solutions, we will need to partner more closely with semiconductor manufacturers.

***Our reliance on a small number of suppliers may result in a shortage of key components, which may adversely affect our business, and our suppliers may experience financial difficulties which could impact their ability to service our needs.***

Certain parts or software used in our products are currently available from either a single supplier or from a limited number of suppliers. Our small relative level of business means we frequently lack influence and significant purchasing power. If we cannot develop alternative sources of these components, if sales of parts or software are discontinued by the supplier, if we experience deterioration in our relationship with these suppliers, or if these suppliers require financing which is not available, there may be delays or reductions in product introductions or shipments, which may materially and adversely affect our operating results.

Because we rely on a small number of suppliers for certain parts, we are subject to possible price increases by these suppliers. Also, we may be unable to accurately forecast our production schedule. If we underestimate our production schedule, suppliers may be unable to meet our demand for components. This delay in the supply of key components may have a materially adverse effect on our business. For suppliers who discontinue parts, we may be required to make lifetime purchases covering future requirements. Over estimation of demand or excessive minimum order quantities may lead to excess inventories that may become obsolete. Part shortages impact availability, lead times and pricing that may be disruptive to our production plans, lead times, margins and may result in lost sales.

Some of our sockets, parts, subassemblies and boards are currently manufactured to our specifications by third-party foreign contract manufacturers and we are sourcing certain parts or options from foreign manufacturers, particularly in China. For example, due to geopolitical considerations, we may not be able to obtain sufficient quantity of these products if and when needed or the quality of these parts or options may not meet our standards, which may result in lost sales.

***If we are unable to attract and retain qualified third-party distributors and representatives, our business may be adversely affected.***

We utilize an internal sales force and third-party distributors and representatives. Therefore, the financial stability of these distributors and representatives is important. Their ability to operate, timely pay us, and to acquire any necessary financing may be affected by the current economic climate. Highly skilled professional engineers use most of our products. To be effective, third-party distributors and representatives must possess significant technical, security, marketing, customer relationships and sales resources and must devote their resources to sales efforts, customer education, training and support. These required qualities limit the number of potential third-party distributors and representatives. Our business will suffer if we cannot attract and retain a sufficient number of qualified third-party distributors and representatives to market our products.

**MARKET CONDITIONS**

***A decline in economic and market conditions may result in delayed or decreased capital spending and delayed or defaulted payments from our customers.***

The broader semiconductor market has experienced a multi-year cyclical downturn which continued into 2025, with notable softness in automotive electronics as a reassessment of electric vehicle capacity and manufacturing plans affected ordering patterns. Demand for capital equipment was further impacted by a reallocation of technology spending, with AI and AI datacenter-related investments taking priority.

The overall data provisioning market represents a significantly larger opportunity than the traditional programming equipment market. While it has been impacted by many of the same macroeconomic forces as the capital equipment segment, the impact has been somewhat more muted, and the cyclical effects are much less pronounced. Furthermore, the entire market is showing early signs of a recovery led by use cases such as the emerging buildout of Edge AI.

Current and future public health crises, geo-political conflicts, and economic barriers, tariffs and constraints can adversely impact the Company's financial performance. Our business is highly impacted by capital spending plans and other economic cycles that affect the users and manufacturers of integrated circuits. The industries are highly cyclical and are characterized by rapid technological change, short product life cycles and fluctuations in manufacturing capacity and pricing and gross margin pressures. In a difficult economic climate, it may take us longer to receive payments from our customers and some of our customers' business may fail, resulting in non-payment. Our market growth outlook and related business decisions may be wrong. These factors could have a material adverse effect on our business and financial condition.

***Our international operations may expose us to additional risks that may adversely affect our business.***

International sales represented approximately 94%, 94%, and 90% of net sales in 2025, 2024 and 2023, respectively. We expect that international sales will continue to be a significant portion of our net revenue. International sales may fluctuate due to various factors, including:

---

| |
|:---|
| current and future global health crisis, similar to COVID-19; |
| economic trade barriers and constraints such as tariffs and taxes; |
| economic challenges in China, Europe and Latin America, as these are major markets for our products, with China being a significant production location; |
| foreign currency exchange rate fluctuations in our major international markets as volatile exchange rates may impact our competitiveness and margins, especially where we have subsidiary operations; |
| unexpected changes in regulatory requirements; |
| difficulties in staffing and managing foreign operations; |
| longer average payment cycles and difficulty in collecting accounts receivable; |
| compliance with applicable export licensing requirements and the Foreign Corrupt Practices Act; |
| product safety and other certification requirements; |
| ability to protect our intellectual property in multiple patent jurisdictions; and/or |
| ability to move cash freely from subsidiaries. |

---

Because we have customers located throughout the world, we have significant foreign receivables, although none are based in Russia or Ukraine. We may experience difficulties in collecting these amounts as a result of payment practices of certain foreign customers, economic uncertainty and regulations in foreign countries, the availability and reliability of foreign credit information, and potential difficulties in enforcing collection terms.

The European Union and European Free Trade Association ("EU") has established certain electronic emission and product safety requirements ("CE"). As applicable, our products currently meet these requirements; however, failure to obtain either CE certification or a waiver for any product may prevent us from marketing that product in Europe. The EU also has directives concerning the Reduction of Hazardous Substances ("RoHS") and we believe we are classified within the EU RoHS Directive category list as Industrial Monitoring and Control Equipment (category 9). We believe all current products meet the RoHS directives. Failure to meet applicable directives or qualifying exemptions may prevent us from marketing certain products in Europe or other territories with similar requirements.

We have subsidiaries in Germany and China and large balances of cash are in our foreign subsidiaries. Our business and financial condition is sensitive to currency exchange rates and any restrictions imposed on their currencies including restrictions on repatriation of cash. A repatriation of cash has, and could in the future, result in tax costs and corresponding deferred tax assets with related tax valuation allowances.

**OPERATIONS**

***Fluctuations in our quarterly operating results may adversely affect our stock price.***

Our operating results tend to vary from quarter to quarter. Our revenue in each quarter substantially depends upon orders received within that quarter. Conversely, our expenditures are based on investment plans and estimates of future revenues. We may, therefore, be unable to quickly reduce our spending if our revenues decline in a given quarter. As a result, operating results for that quarter will suffer. Our operating results for any one quarter are not necessarily indicative of results for any future periods. Other factors, which may cause our quarterly operating results to fluctuate, include:

· increased competition;

· timing of new product announcements and timing of development expenditures;

· product or service releases and pricing changes by us or our competitors;

· market acceptance or delays in the introduction of new products or services;

· production constraints, including part shortages impact on us and our supply chains;

· quality issues;

· labor or material constraints;

· timing of significant orders;

· sales channel mix of direct vs. indirect distribution;

· civil unrest, war or terrorism;

· health issues such as the outbreak of the coronavirus or other viruses impacting workers, suppliers, customers, travel, or our facilities;

· customers' budgets;

· changes in accounting rules, tax or other legislation;

· adverse movements in exchange rates, interest rates, inflation or tax rates;

· cyclical and seasonal nature of demand for our customers' products;

· general economic conditions in the countries where we sell products;

· expenses and delays obtaining authorizations in setting up new operations or locations; and/or

· facilities relocations.

---

Due to any of the foregoing factors, it is possible that in some future quarters, our operating results will be below the expectations of analysts and investors.

***We have a history of operating losses and may be unable to generate enough revenue to achieve and maintain profitability.***

We have incurred operating losses in 8 of the last ten years. We operate in a cyclical industry. We will continue to examine our level of operating expense based upon our projected revenues. Any planned increases in operating expenses may result in losses in future periods if projected revenues are not achieved or the investment level required is too large. As a result, we may need to generate greater revenues than we have recently in order to maintain profitability. However, we cannot provide assurance that our revenues will increase and our business strategies will be successful, resulting in future losses.

***The loss of key employees may adversely affect our operations.***

During 2025, the Company underwent significant leadership transitions, including the appointment of Charles DiBona as Chief Financial Officer in August 2025, replacing Gerald Ng. Additional changes were made in sales, marketing, and engineering leadership as part of the Company's strategic transformation. While management believes these changes strengthen the Company's capabilities, leadership transitions carry inherent risks including potential disruption to ongoing operations and loss of institutional knowledge.

We have employees located in the U.S., Germany and China. We also utilize independent contractors for specialty work, primarily in research and development, and utilize temporary workers to adjust capacity to fluctuating demand. Many of our employees are highly skilled, and our continued success will depend in part upon our ability to attract and retain employees who can be in great demand within the industry. None of our employees are represented by a collective bargaining unit, and we believe relations with our employees are favorable, though no assurance can be made that this will be the case in the future. In China, our workers have benefits and similar arrangements provided under a "FSCO" labor agreement, and we could be adversely affected if we were unable to continue that arrangement.

***We may need to raise additional capital and our future access to capital is uncertain.***

Cash at December 31, 2025 was $7.9 million.

Our past revenues have sometimes been, and our future revenues may again be, insufficient to support the expense of our operations and any expansion of our business. We may therefore need additional equity or debt capital to finance our operations. If we are unable to generate sufficient cash flows from operations or to obtain funds through additional debt, lease or equity financing, we may have to reduce some or all of our development and sales and marketing efforts and limit the expansion of our business.

We believe that we have sufficient cash or working capital available under our operating plan to fund our operations and capital requirements through at least the next one-year period. In the event we require additional cash for U.S. operations or other needs, we may choose to repatriate some, or all, of the cash held in our foreign subsidiaries. There may be tax, legal and other impediments to any repatriation actions. 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 an adverse impact on our financial position, liquidity, or results of operations and may require us to reduce expenditures and/or seek additional financing.

Therefore, we may seek additional funding through public or private debt or equity financing or from other sources. We have no commitments for additional financing and given a potential future unfavorable economic climate and our financial results, we may experience difficulties in obtaining funding on favorable terms, if at all. Any financing we obtain may contain covenants that restrict our freedom to operate our business or may require us to issue securities that have rights, preferences or privileges senior to our Common Stock and may dilute your ownership interest.

***Our stock price may be volatile and, as a result, our shareholders may lose some or all their investment.***

The stock prices of technology companies tend to fluctuate significantly. We believe factors such as announcements of new products or services by us or our competitors and quarterly variations in financial results and outlook may cause the market price of our Common Stock to fluctuate substantially. In addition, overall volatility in the stock market, particularly in the technology sector, is often unrelated to the operating performance of companies. If these market fluctuations continue in the future, they may adversely affect the price of our Common Stock.

**CYBERSECURITY RISKS**

***Cybersecurity incidents could result in loss of revenue, business disruptions, remediation costs, legal claims and proceedings, regulatory actions, reporting delays, increased insurance costs, or damage to the Company's reputation which could adversely impact or operations and financial results.***

In August 2025, the Company experienced a ransomware incident that resulted in the shutdown of most global operating systems, business disruptions including the inability to timely process certain shipments, and significant remediation costs of approximately $388,000 in the third quarter of 2025. While the incident was contained and remediated by September 2025 and the Company does not believe any customer data was compromised, the incident demonstrated the Company's vulnerability to cyber attacks and the potential for material operational and financial impacts. The Company has implemented significant enhancements to its cybersecurity infrastructure and processes; however, no assurance can be given that these measures will prevent future incidents. A future cybersecurity incident could result in loss of revenue, business disruptions, remediation costs, legal claims and proceedings, regulatory actions, reporting delays, increased insurance costs, or damage to the Company's reputation. The costs of preventing, responding to and recovering from cybersecurity incidents may be material.

***Cybersecurity breaches or terrorism could result in liabilities or costs as well as damage to or loss of our data or customer access to our website and information systems. The collection, storage, transmission, use and disclosure of user data and personal information, if accessed improperly, could give rise to liabilities or additional costs as a result of laws, government regulations and evolving views of personal privacy rights.***

Cybersecurity attacks may increase due to geo-political disagreements with countries and regions such as Russia, China, Korea and the Middle East. Cybersecurity breaches or terrorism could result in the exposure or theft of private or confidential information as well as interrupt our business, including denying customer access to our website and information systems. We transmit, and in some cases store, end-user data, including personal information. In jurisdictions around the world, personal information is becoming increasingly subject to legislation and regulations intended to protect consumers' privacy and security. The interpretation of privacy and data protection laws and regulations regarding collection, storage, transmission, use and disclosure of such information in some jurisdictions are unclear and evolving. These laws may be interpreted and applied in conflicting ways from country to country and in a manner that is not consistent with our current data protection practices. Complying with these varying international requirements could cause us to incur additional costs and change our business practices. Because our services are accessible in many foreign jurisdictions, some of these jurisdictions may claim that we are required to comply with their laws, even if we have no local entity, employees or infrastructure. We could be forced to incur significant expenses if we were required to modify our products, our services or our existing security and privacy procedures to comply with new or expanded regulations.

**REGULATORY REQUIREMENTS**

***Failure to comply with increasing regulatory requirements may adversely affect our stock price and business.***

As a public company, we are subject to numerous governmental and stock exchange requirements with which we believe we are in compliance. Our failure to meet regulatory requirements and exchange listing standards may result in actions such as: the delisting of our stock, impacting our stock's liquidity; SEC enforcement actions; and securities claims and litigation. Increased regulations pushed onto public companies may have a disproportionate impact to smaller public companies.

The Sarbanes-Oxley Act of 2002 and the Securities and Exchange Commission (SEC)SEC have requirements that we may fail to meet or we may fall out of compliance with, such as the internal controls auditor attestation required under Section 404 of the Sarbanes-Oxley Act of 2002, with which we are not currently required to comply as we are a smaller reporting company. We assume that we will continue to have the status of a smaller reporting company based on the aggregate market value of the voting and non-voting shares held as of June 30, 2025. If we fail to achieve and maintain the adequacy of our internal controls, as such standards are modified, supplemented or amended from time to time, we may not be able to ensure that we can conclude on an ongoing basis that we have effective internal controls over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act of 2002. Moreover, effective internal controls, particularly those related to revenue recognition, are necessary for us to produce reliable financial reports and are important to help prevent financial fraud. If we cannot provide reliable financial reports or prevent fraud, our business and operating results could be harmed, investors could lose confidence in our reported financial information, and the trading price of our stock could drop significantly.

As previously disclosed in the Annual Report on Form 10-K for the year ended December 31, 2024, the Company identified a material weakness in internal control over financial reporting related to user access and segregation of duties within certain IT systems. During 2025, the Company implemented remediation actions including enhancements to system access controls, improved segregation of duties, and expanded monitoring and review procedures. Meanwhile, the Company has identified an additional instance of material weakness, and while management has taken steps to remediate these internal control issues related to reviews and reporting, these weaknesses did persist during the reporting period of this Form 10-K for the year ended December 31, 2025. See item 9A.

While we have policies and procedures in place designed to prevent corruption and bribery, because our business is significantly international, violations of the Foreign Corrupt Practices Act (FCPA) could have a significant adverse effect on our business due to the disruption and distraction of an investigation, financial penalties and criminal penalties.

***Government regulations regarding the use of "conflict" minerals and potential climate and ESG requirements could adversely affect our prospects and results of operations.***

Regulatory requirements regarding disclosure of our use of "conflict" minerals mined from the Democratic Republic of Congo and adjoining countries could affect the sourcing and availability of minerals used in the manufacture of certain products. Although we do not buy raw materials, manufacture, or produce any electronic equipment using conflict minerals directly, some components provided by our suppliers and contained in our products contain conflict minerals. Our goal is for our products to be conflict free. As a result, there may only be a limited pool of suppliers who provide conflict-free metals, and we cannot assure you that we will be able to obtain products in sufficient quantities or at competitive prices. Single source suppliers may not respond or respond negatively regarding conflict mineral sourcing, and we may be unable to find alternative sources to replace them. Also, because our supply chain is complex, we may face reputational challenges with our customers and other stakeholders if we are unable to sufficiently verify the origins for all metals used in the products that we sell. Further, if we are unable to comply with the new laws or regulations or if our efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to practice, regulatory authorities may initiate legal proceedings against us. We may need to incur additional costs and invest additional resources, including management's time, to comply with the new regulations and additional reporting and disclosure obligations.

Climate focused regulations and related disclosures are a similar evolving regulatory area, and we may be required to invest in systems, processes and personnel to address new requirements in the ESG area. These will require significant costs, work and reputational risk for failing to meet requirements, with miniscule impact to the global environment.

**Item 1B. Unresolved Staff Comments**

None.

**Item 1C. Cybersecurity**

The following discussion of our cybersecurity program reflects conditions as of December 31, 2025, including significant enhancements implemented in response to the August 2025 cybersecurity incident described below.

On August 16, 2025, the Company was the subject of a targeted ransomware incident affecting certain internal IT systems. Upon discovering the incident, the Company promptly activated its response protocols and implemented containment measures, including proactively shutting down most operating systems globally to manage the safety of the overall global systems environment. The Company engaged leading cybersecurity experts to support system recovery and conduct a comprehensive forensic investigation. The investigation determined that the attack originated through a vulnerability in a commercially available third-party firewall service provider and was not specifically targeted at Data I/O. By September 2025, the incident had been completely contained and remediated, all global systems were restored, and the Company does not believe it has any remaining risk exposure from the incident. The remediation and associated professional fees resulted in approximately $388,000 of one-time costs, primarily recorded in the third quarter of 2025. The incident was reported on Form 8-K filed with the SEC on August 21, 2025.

As an outcome of the incident, the Company's IT systems and cybersecurity posture were strengthened, with improved corporate processes and enhanced security infrastructure. Remediation actions included enhancements to system access controls, improved network segmentation, migration of critical systems to cloud-based solutions, and expanded monitoring and review procedures. See "Risk Factors - Cybersecurity incidents could result in loss of revenue, business disruptions, remediation costs, legal claims and proceedings, regulatory actions, reporting delays, increased insurance costs, or damage to the Company's reputation which could adversely impact or operations and financial results."

***CYBERSECURITY GOVERNANCE***

The Company's Board of Directors has oversight responsibility for our strategic and operational risks. The Audit Committee of the Board of Directors is responsible for board-level oversight of cybersecurity risk. The cybersecurity program is managed by our outsourced IT infrastructure team with oversight and coordination by our CFO, Charles DiBona, who reports directly to our CEO.

During the third quarter of 2025, in connection with the appointment of Charles DiBona as Chief Financial Officer, the Company formalized CFO oversight of the cybersecurity program. Following the August 2025 ransomware incident, the Audit Committee increased the frequency of cybersecurity reporting and the Company enhanced its incident response protocols. The cybersecurity program is managed by the Company's new outsourced IT infrastructure team, which provides 24/7 monitoring and response capabilities, with oversight and coordination by the CFO, who reports directly to the CEO. The Audit Committee receives regular updates on cybersecurity matters, including threat assessments, incident response activities, and the status of remediation efforts.

***CYBERSECURITY RISK MANAGEMENT AND STRATEGY***

The Company's cybersecurity risk management program is integrated into its overall enterprise risk management framework. Following the August 2025 ransomware incident, the Company significantly enhanced its cybersecurity risk management processes. These enhancements included: patching the third-party firewall service provider through which the attack originated and evaluating replacement providers; implementing improved network segmentation and access controls; expanding endpoint detection and response capabilities; enhancing backup and disaster recovery procedures; conducting comprehensive vulnerability assessments across all IT systems; and providing additional cybersecurity awareness training to all employees. The Company also engaged independent cybersecurity consultants to review and validate the effectiveness of its enhanced security posture. As of September 30, 2025, all remediation activities had been completed and all global systems had been restored to full operational status. The Company continues to assess and adapt its cybersecurity risk management practices to address evolving threats.

**Item 2. Properties**

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 operations services. The total annual gross or base lease payments during 2025 and 2024 were approximately $735,000 and $795,000, respectively. The lease payment decrease in 2024 was due primarily to a reduction in lease rates for our Redmond, Washington and Shanghai, China facilities. The lower rates reflect the real estate market conditions as part of the lease extensions which occurred in the fourth quarter of 2024. The Redmond lease was renewed and extended by 3.75 years and the Shanghai, China lease was renewed and extended by 3 years.

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.

**Item 3. Legal Proceedings**

From time to time, we may be involved in litigation relating to claims arising out of our operations in the normal course of business. As of December 31, 2025, we were not a party to any legal proceedings or aware of any indemnification agreement claims, the adverse outcome of which in management's opinion, individually or in aggregate, would have a material adverse effect on our results of operations or financial position.

***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.

\* includes service and parts sales associated with equipment service contracts

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**

---

| | | | |
|:---|:---|:---|:---|
|  | 2025 | Change | 2024 |
| (in thousands) |  |  |  |
| Research and development | $6531 | 4.7% | $6240 |
| Percentage of net sales | 30.4% |  | 28.7% |

---

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 ("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 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.

|  | 2025 | Change | 2024 |
| (in thousands) |  |  |  |
| Working capital | $12270 | $(4065) | $16085 |

---

Working capital decreased by $4.1 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.

<br>**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**<br>

Board of Directors and Stockholders

Data I/O Corporation

**Opinion on the financial statements** 

We have audited the accompanying consolidated balance sheets of Data I/O Corporation (a Washington corporation) and subsidiaries (the "Company") as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive income (loss), stockholders' equity, and cash flows for each of the two years in the period ended December 31, 2025, and the related notes and financial statement schedules included under Item 15(a)(2) (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

**Basis for opinion** 

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical audit matter**

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

*Net Realizable Value of Inventory*

As described further in Note 1 to the financial statements, management measures the net realizable value of inventory based on estimated reductions to inventory for obsolete, slow-moving, excess and non-salable inventory by reviewing current transactions and forecasted demand. We identified net realizable value of inventory specifically as a critical audit matter.

---

| |
|:---|
| 33 |
| *[**Table of Contents**](#toc2)* |

---

The principal considerations for our determination that the net realizable value of inventory represents a critical audit matter are that the assessment of the valuation of inventory is complex and includes an estimate of forecasted demand. The demand estimate is subjective and requires the Company to consider significant assumptions such as economic conditions, technological advances, historical usage, and consumer trends, which are subject to significant uncertainty and therefore require significant auditor judgement.

Our audit procedures related to the net realizable value of inventory included the following, among others:

· To test the adequacy of the Company's allowance for excess and obsolete inventories, we performed substantive audit procedures that included, among others, testing the completeness and accuracy of the underlying data used in the estimation calculations, specifically those related to inventory movements and aging. We also evaluated the reasonableness of significant assumptions including the estimated reserve percentage and other significant assumptions through inquiry of management and personnel outside of finance team and analytical procedures.

/s/ GRANT THORNTON LLP

We have served as the Company's auditor since 2001.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

***Nature of Operations***

Data I/O Corporation ("Data I/O", "We", "Our", "Us") is the leading global provider of advanced security and data deployment solutions for microcontrollers, security ICs and memory devices. 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.

***Principles of Consolidation***

The consolidated financial statements include the accounts of Data I/O Corporation and wholly owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation.

***Use of Estimates***

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Significant estimates include:

· Revenue Recognition

· Allowance for Credit Losses

· Inventory Obsolescence Allowances

· Warranty Accruals

· Tax Valuation Allowances

· Share-based Compensation

***Foreign Currency Translation***

Assets and liabilities of foreign subsidiaries are translated at the exchange rate on the balance sheet date. Revenues, costs and expenses of foreign subsidiaries are translated at average rates of exchange prevailing during the year. Translation adjustments resulting from this process are charged or credited to stockholders' equity. Realized and unrealized gains and losses resulting from the effects of changes in exchange rates on assets and liabilities denominated in foreign currencies are included in non-operating expense as foreign currency transaction gains and losses.

***Cash and Cash Equivalents***

All highly liquid investments purchased with an original maturity of 90 days or less are considered cash equivalents. We maintain our cash and cash equivalents with major financial institutions in the United States of America, which are insured by the Federal Deposit Insurance Corporation (FDIC), and in foreign jurisdictions. Deposits in U.S. banks exceed the FDIC insurance limit. We have not experienced any losses on our cash and cash equivalents. Cash and cash equivalents held in foreign bank accounts, typically in local currency, in China and Germany, totaled $5.2 million and $4.3 million at December 31, 2025 and 2024, respectively. This cash held in subsidiaries have restrictions and costs associated with repatriations, currency conversions, and complying with government policies, regulations and controls, especially in China.

***Fair Value of Financial Instruments***

Certain financial instruments are carried at cost on the consolidated balance sheets, which approximates fair value due to their short-term, highly liquid nature. These instruments include cash and cash equivalents, accounts receivable, accounts payable and accrued expenses, and other short-term liabilities.

***Trade*** ***Accounts Receivable***

Majority of our accounts receivable are due from companies in the electronics manufacturing industries. Credit is extended based on an evaluation of a customer's financial condition and, generally, collateral is not required. Account receivables are typically due within 30 to 60 days and are stated at amounts due net of an allowance for credit losses. Accounts receivable outstanding longer than the contractual payment terms are considered past due. We determine the allowance by considering a number of factors, including a forward-looking expectation based upon the condition of the general economy and the industry as a whole and our previous bad debt experience, as well as the length of time trade accounts receivable are past due, the industry and geographic payment practices involved, and the customer's current ability to pay their obligation to us. We write off accounts receivable when they become uncollectible, and payments subsequently received on such receivables are credited to the allowance for credit losses.

***Inventories***

Inventories are stated at the lower of cost or net realizable value with cost being the currently adjusted standard cost, which approximates cost on a first-in, first-out basis. We estimate changes to inventory for obsolete, slow-moving, excess and potential non-salable inventory by reviewing current transactions and forecasted product demand. We evaluate our inventories on an item-by-item basis and record an adjustment (lower of cost or net realizable value) accordingly.

***Property, Plant and Equipment***

Property, plant and equipment, including leasehold improvements, are stated at cost, and depreciation is calculated over the estimated useful lives of the related assets or lease terms on the straight-line basis. We depreciate substantially all property, plant and equipment over periods of three to seven years. We depreciate leasehold improvements over the remaining portion of the lease or over the expected life of the asset if less than the remaining term of the lease.

Property, plant and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Based on these evaluations, for the years ended December 31, 2025 and 2024, no impairment was noted or recorded for property, plant and equipment.

***Patent Costs***

We expense external costs, such as filing fees and associated attorney fees, incurred to obtain initial patents, but capitalize patents obtained through acquisition as intangible assets. We also expense costs associated with maintaining and defending issued patents.

***Income Taxes***

Income taxes 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 ("OB3") was enacted, which includes provisions allowing for the immediate expensing of domestic research and experimental ("R&E") expenditures under Section 174A, effective for tax years beginning after December 31, 2021. The Company has elected not to accelerate the amortization of unamortized R&E costs incurred in prior years. As a result, the Company continues to amortize R&E expenditures over the five-year period as previously required under Section 174. The Company will continue to evaluate the impact of OB3 on future periods.

***Share-Based Compensation***

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

***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, 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. Total deferred revenue which represents undelivered performance obligations for installation, service, support and extended maintenance contracts was $1.5 million and $1.7 million and the portion expected to be recognized within one year was $1.5 million and $1.5 million for December 31, 2025 and 2024, respectively. Deferred revenue as of December 31, 2023 was $1.4 million.

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

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:

---

| | | |
|:---|:---|:---|
| Net sales by type | 2025 | 2024 <br>As Revised |
| (in thousands) |  |  |
| Platform Sales | $8997 | $10466 |
| Adapter Sales | 7903 | 7190 |
| Software and Services Sales \* | 4600 | 4113 |
| Total | $21500 | $21769 |

---

\* 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 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.

***Leases – Accounting Standards Codification 842***

Leases arise from contracts which convey the right to control the use of identified property or equipment for a period of time in exchange for consideration. Our leasing arrangements are primarily for office and manufacturing facility space we use to conduct our operations. In addition, there are automobiles, and a small amount of office equipment leased. We determine whether contracts include a lease at the inception date, which is generally upon contract signing, considering factors such as whether the contract includes an asset which is physically distinct, which party obtains substantially all of the capacity and economic benefit of the asset, and which party directs how, and for what purpose, the asset is used during the contractual period of use. Our leases commence when the lessor makes the asset available for our use. At commencement, we record a lease liability at the present value of future lease payments, net of any future lease incentives to be received. Some of our lease agreements include cancellable future periods subject to termination or extension options. We include cancellable lease periods in our future lease payments when we are reasonably certain to continue to utilize the asset for those periods. We calculate the present value of future lease payments at commencement using a discount rate which we estimate as the collateralized borrowing rate we believe would be incurred on our future lease payments over a similar term. At commencement, we record a corresponding right-of-use asset, which is calculated based on the amount of the lease liability, adjusted for any advance lease payments paid, initial direct costs incurred or lease incentives received prior to commencement. Right-of-use assets are subject to evaluation for impairment or disposal on a basis consistent with other long-lived assets.

Leases are classified at commencement as either operating or finance leases. As of December 31, 2025, all leases are classified as operating leases. Rent expense for operating leases is recognized on the straight-line method over the term of the agreement beginning on the lease commencement date.

In accounting for leases, we utilize certain practical expedients and policy selections available under the lease accounting standard. We do not record right-of-use assets or lease liabilities for leases with terms of 12 months or less. For contracts containing real estate leases, we do not combine lease and non-lease components. The primary impact of this policy election is that we do not include in our calculation of lease liabilities any fixed and non-cancellable future payments due under the contract for items such as common area maintenance, utilities and other costs. Lease-related costs which are variable rather than fixed are expensed in the period incurred.

Assumptions, judgments and estimates impacting the carrying value of our right-of-use assets and liabilities include evaluating whether an arrangement contains a lease, determining whether the lease term should include any cancellable future periods, estimating the discount rate used to calculate our lease liabilities, estimating the fair value and useful life of the leased asset for the purpose of classifying the lease as an operating or finance lease, evaluating whether a lease contract amendment represents a new lease agreement or a modification to the existing lease and evaluating our right-of-use assets for impairment.

***Research and Development***

Research and development costs are generally expensed as incurred.

***Advertising Expense***

Advertising costs are expensed as incurred. Total advertising expenses were approximately $139,000 and $92,000 for the years ending December 31, 2025 and 2024, respectively.

***Warranty Expense***

We record a liability for an estimate of costs that we expect to incur under our basic limited warranty when product revenue is recognized. Factors affecting our warranty liability include the number of units sold and historical and anticipated rates of claims and costs per claim. We normally provide a warranty for our products for defects for periods ranging from ninety days to one year. We provide for the estimated cost that may be incurred under our product warranties and periodically assess the adequacy of our warranty liability based on changes in the above factors. We record revenues on extended warranties on a straight-line basis over the term of the related warranty contracts. Service costs are expensed as incurred.

***Earnings (Loss) Per Share***

Basic earnings (loss) per share exclude any dilutive effects of stock options. Basic earnings (loss) per share are computed using the weighted-average number of common shares outstanding during the period. Diluted earnings per share are computed using the weighted-average number of common shares and common stock equivalent shares outstanding during the period. The common stock equivalent shares from equity awards used in calculating diluted earnings per share were 86,000 and 74,000 for the years ended December 31, 2025 and 2024, respectively. Excluded from the computation of diluted earnings per share were options to purchase 200,000 and 200,000 shares of common stock because of the net loss in 2025 and 2024, thus the options were anti-dilutive for the years ended December 31, 2025 and 2024, respectively.

***Diversification of Credit Risk***

Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of trade receivables. Our trade receivables are geographically dispersed and include customers in many different industries. Our consolidated accounts receivable balance as of December 31, 2025 and 2024 includes foreign accounts receivable in the functional currency of our foreign subsidiaries amounting to $612,000 and $1.2 million, respectively. We generally do business with our foreign distributors in U.S. Dollars. We believe that the risk of loss is significantly reduced due to the diversity of our end customers and sales geographies. We perform on-going credit evaluations of our customers' financial conditions and require collateral, such as letters of credit and bank guarantees, or prepayment whenever deemed necessary.

The following represented greater than 10% of our accounts receivable for the applicable years:

---

| | | |
|:---|:---|:---|
| Percentage of Accounts Receivable | 2025 | 2024 |
| Number of customers | 3 | 2 |
| Approximate percentage of accounts receivable balance | 49% | 43% |

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Percentage of Customer 2 | 12% | 15% |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Percentage of Customer 3 | 11% |  |

***Reclassifications***

Certain prior-year amounts have been reclassified within the notes to the consolidated financial statements to conform to the current-year presentation. These reclassifications had no impact on the consolidated balance sheets, statements of operations, statements of comprehensive income (loss), statements of stockholders' equity or cash flows as previously reported.

***New******Accounting Pronouncements – Standards Issued and Implemented***

In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures," which expands disclosure requirements for income taxes, specifically related to the rate reconciliation and income taxes paid. ASU 2023-09 became effective for the Company's annual period beginning January 1, 2025, and has been applied on a prospective basis in these consolidated financial statements.

***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, and should be applied retrospectively to all comparative periods. Early adoption is permitted. The Company is currently evaluating the effects of adopting this new accounting guidance.

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 operations services. The lease payment decrease in 2025 versus 2024 was due primarily to the realization of a full year of the reduction in lease rates for our Redmond, Washington and Shanghai, China facilities effected in 2024 when, the Redmond lease was renewed and extended by 3.75 years and the Shanghai, China lease was renewed and extended by 3 years. Right-of-use assets obtained in exchange for lease liabilities was approximately $2.5 million the year ended December 31, 2024

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 December 31, 2025 and 2024:

At December 31, 2025, the weighted average remaining lease term is 3.2 years and the weighted average discount rate is 5%.

***Lessor Arrangements***

During the year ended December 31, 2025, the Company recognized approximately $0.6 million of revenue from one sales-type lease related to the lease of programming equipment, which is included in Platform Sales in the consolidated statements of operations. The Company did not recognize sales-type lease revenue during the year ended December 31, 2024. The Company does not typically enter into sales-type lease arrangements and does not expect such arrangements to be recurring.

We determined the residual value of this leased equipment based on its estimated end-of-term market value. We estimate the residual value of leased equipment at the inception of the lease based on a number of factors, including historical wholesale market sales prices, past remarketing experience and any known significant market/product trends. We also consider the following critical factors in our residual value estimates: lease term, market size and demand, total expected hours of usage, machine configuration, application, location, model changes, quantities, third-party residual guarantees and contractual customer purchase options. Although the lease permits month-to-month continuation, the Company has concluded that the lessee is reasonably certain to exercise the purchase option. Accordingly, as of December 31, 2025, substantially all remaining undiscounted lease payments related to the Company's sales-type lease are expected to be received in 2026. The timing of such payments is consistent with the Company's estimate of the exercise of the purchase option and supports the carrying amount of the net investment in the lease recognized as of December 31, 2025.

At December 31, 2025, the Company's net investment in sales-type leases was $0.4 million, which is included in Trade accounts receivable, net on the consolidated balance sheets. The net investment represents the present value of future lease payments and the expected purchase option proceeds, discounted at the rate implicit in the lease.

**NOTE 7 – 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. On December 31, 2025, we had contracts with a commitment of approximately $905,000, of which approximately $585,000 is expected to be paid during 2026, $160,000 during 2027, $160,000 during 2028, $0 during 2029, 2030 and thereafter.

**NOTE 8 – CONTINGENCIES**

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

**NOTE 9 – STOCK AND RETIREMENT PLANS**

***Stock Option Plans***

At December 31, 2025, there were 400,838 shares available for future grant under the Data I/O Corporation 2023 Omnibus Incentive Compensation Plan (the "2023 Plan"). At December 31, 2025, there were shares of Common Stock reserved for issuance for outstanding awards. Pursuant to the 2023 Plan, options are granted to our officers and key employees with exercise prices equal to the fair market value of the Common Stock at the date of grant and generally vest over four years. Options granted under the plan have a maximum term of six years from the date of grant. Stock awards are granted under the 2023 Plan which for RSU awards generally vest over three or four years and one year for non-employee Directors. Performance Share Unit (PSU) awards vest based upon three-year performance achievement. The performance measures for the PSUs awarded in 2023 are cumulative revenue growth over the three-year period ending December 31, 2025. The performance measures for the PSUs awarded in 2024 are revenue growth targets, EBITDA targets and for Engineers, project objectives for the three-year period ending December 31, 2026. There were no PSU awards granted in 2025.

***Employee Stock Purchase Plan***

Under the Employee Stock Purchase Plan ("ESPP"), eligible employees may purchase shares of our Common Stock at six-month intervals at 95% of the fair market value on the last day of each six-month period. Employees may purchase shares having a value not exceeding ten percent of their gross compensation during an offering period. During 2025 and 2024, a total of 4,250 and 5,019 shares, respectively, were purchased under the plan at average prices of $3.00 and $2.85 per share, respectively. At December 31, 2025 and 2024, 14,637 and 16,955 shares were reserved for future grant respectively.

***Stock Appreciation Rights Plan***

We have a Stock Appreciation Rights ("SAR") Plan under which each director, executive officer or holder of 10% or more of our Common Stock has a SAR with respect to each exercisable stock option. The SAR entitles the SAR holder to receive cash from us for the difference between the market value of the stock and the exercise price of the option in lieu of exercising the related option. SARs are only exercisable following a tender offer or exchange offer for our stock or following approval by shareholders of any merger, consolidation, reorganization or other transaction providing for the conversion or exchange of more than 50% of the common shares outstanding. As no event has occurred which would make the SARs exercisable, and no such event is deemed probable, no compensation expense has been recorded under this plan. At December 31, 2025 and 2024, there were 200,000 and 200,000 SARs outstanding, respectively.

***Retirement Savings Plan***

We have a savings plan that qualifies as a cash or deferred salary arrangement under Section 401(k) of the Internal Revenue Code. Under the plan, participating U.S. employees may defer their pre-tax salary or post-tax salary if Roth is elected, subject to IRS limitations. In fiscal year 2025, we contributed one dollar for each dollar contributed by a participant on the first two percent and $.50 for each dollar contributed by participant on the next four percent of a participant's eligible earnings. Our matching contribution expense for the savings plan, net of forfeitures, was approximately $197,000 and $217,000 in 2025 and 2024, respectively. Employer matching contributions owed to the plan were $219,000 and $230,000 at December 31, 2025 and 2024, respectively.

**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. The impact on our results of operations of recording share-based compensation for the years ended December 31, 2025 and 2024 was as follows:

During the years ended December 31, 2025 and 2024, 1,100 and 86,507 shares, respectively, were withheld from issuance related to restricted stock units vesting and stock option exercises to cover employee taxes and stock options exercise price.

Non-employee directors Restricted Stock Units ("RSUs") typically vest over the earlier of one year or the next annual meeting of shareholders and Non-Qualified stock options vest over three years and have a six-year exercise period. Employee RSUs typically vest annually over three or four years and employee Non-Qualified stock options typically vest quarterly over four years and have a six-year exercise period. 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. The table above includes performance shares granted in 2024 of 124,000 shares at the target performance level (the threshold level would be 50% and the maximum level would be 150% of the target level).

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 makes 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.

As noted in the 2025 rate reconciliation above, we derive the effective tax rate benefit, or detriment, attributed to non-U.S. income taxed at different rates primarily from our operations in China, among others.

**Deferred Taxes**

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts for income tax purposes. Significant components of our deferred tax assets and liabilities at the end of each period were as follows:

---

| | | |
|:---|:---|:---|
| (In thousands) | 2025 | 2024 |
| Allowance for credit losses | $6 | $4 |
| Inventory and product return reserves | 1419 | 1666 |

| U.S. credit carryforwards | 1642 | 1564 |
| Gross deferred tax assets | $10578 | $9261 |

| Deferred tax liabilities - foreign | (250) | - |
| Total gross deferred tax liabilities | (322) | (22) |
|  | $(250) | $0 |

---

Changes in the valuation allowance for deferred tax assets were as follows:

---

| | |
|:---|:---|
|  | 2025 |
| Balance at Beginning of Year | $9239 |
| &nbsp;&nbsp;&nbsp;&nbsp;Additions charged to expenses/other accounts | 1267 |
| &nbsp;&nbsp;&nbsp;&nbsp;(Deductions) recoveries, net |  |
| Balance at End of Year | $10506 |

---

The change in valuation allowance is substantially attributable to the uncertainty regarding the realizability of our U.S. deferred tax assets. As of December 31, 2025, our federal and non-U.S. net operating loss carryforwards for income tax purposes were $19,345,000 and $1,690,000 respectively. The majority of the federal and non-U.S. net operating loss carryforwards have multiple expiration dates. The remaining federal U.S. net operating loss carryforwards expire at various dates through 2034.The Company has determined that certain undistributed earnings of its foreign subsidiaries are indefinitely reinvested. Accordingly, no deferred income taxes have been recorded on those earnings. The deferred tax liability related to these indefinitely reinvested earnings that has not been recognized was approximately $294,000 as of December 31, 2025. Deferred income taxes have been recorded for undistributed foreign earnings that are expected to be repatriated.

Historically, we have incurred minimal interest expense, and no penalties associated with tax matters. We have adopted a policy whereby amounts related to penalties associated with tax matters are classified as general and administrative expense when incurred and amounts related to interest associated with tax matters are classified as interest income or interest expense.

Tax years that remain open for examination include 2022, 2023, 2024 and 2025 in the United States of America. In addition, various tax years from 2004 to 2014 may be subject to examination if we utilize the net operating losses and credit carryforwards from those years in our current or future year tax returns.

**<u>Income Tax Paid</u>**

We adopted ASU 2023-09 on a prospective basis for the year ended December 31, 2025 and have included the following table as a result of our adoption, which presents income taxes paid (net of refunds received) for the year ended December 31, 2025:

**NOTE 13 – SEGMENT INFORMATION**

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

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

Our Chief Operating Decision Maker ("CODM") is the President/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:

---

**NOTE 14 – GEOGRAPHIC INFORMATION**

Major operations outside the U.S. include sales, engineering and service support by subsidiaries in Germany as well as in China, which also manufactures some of our products. None of our employees are represented by a collective bargaining agreement.

We determine international sales by the international geographic destination into which the products are sold and delivered and include not only sales by foreign subsidiaries but also export sales from the U.S. to our foreign distributors and to our representatives' customers. Certain revenues recognized over time (for instance, multi-period service contracts under ASC 606) are allocated to geographic regions based on estimates, because our systems do not track the country of these revenues as they are deferred and recognized. In such cases, we allocate revenue to countries proportionally based on the initial contract value by country, which we believe is a reasonable approximation. International sales do not include transfers between Data I/O and our foreign subsidiaries. Long-lived assets are reported in the region where the asset is physically located, and consist of property, plant and equipment and other long-term assets.

The following tables provide summary operating information by geographic area:

**NOTE 15 – 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 year ended December 31, 2024. 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 year ended December 31, 2024 to enhance comparability.

**NOTE 16 – SUBSEQUENT EVENTS**

In preparing the financial statements, the Company has reviewed all known events which occurred after December 31, 2025 through the date on which the financial statements are available for issuance, for potential recognition or disclosure in the consolidated financial statements and footnotes.

In January 2026, the Company filed a shelf registration statement on Form S-3 with the Securities and Exchange Commission, providing the ability to issue up to $20 million of equity securities. The shelf registration provides financial flexibility for potential strategic initiatives, including acquisitions aligned with the Company's growth strategy.

Also in January, the Company took steps to realign its German subsidiary, scaling back on some functions and bringing a number of roles back to headquarters which resulted in the elimination of several positions in the German subsidiary.

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.

**Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure<u>.</u>**

None.

**Item 9A. Controls and Procedures**

As previously disclosed in the Company's Annual Report on the Form 10-K for the year ended December 31, 2024, the Company identified a material weakness in our internal control over financial reporting in the areas of user access and segregation of duties related to the information technology system that support the Company's financial reporting processes. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's annual or interim financial statements will not be prevented or detected on a timely basis.

During 2025, the Company implemented enhancements to system access controls, user access provisioning and de-provisioning controls, role-based access restrictions, monitoring controls over privileged access, improved segregation of duties, and expanded monitoring and review procedures in efforts to address the previously identified IT user access control deficiencies. The August 2025 ransomware incident prompted additional IT infrastructure improvements that support both cybersecurity and internal control objectives. Specifically, the Company removed administrative access from all employees outside of the IT department. We instituted regular reviews of access rights across all systems, and we implemented improved segregation of duties with respect to financial transactions and reporting, Management completed testing of the design and operating effectiveness of the revised controls and procedures during 2025.

While these actions were taken to improve access management and security controls, the material weakness was not fully remediated as of December 31, 2025. A material weakness continues to exist related to ineffective user access and segregation-of-duties controls within IT systems that support financial reporting, Accordingly, management concluded that the conditions underlying the previously identified IT-related material weakness remained present as of December 31, 2025. Due to this material weakness, there is a reasonable possibility that a material misstatement of the Company's annual or interim financial statements would not be prevented or detected on a timely basis.

In addition, management determined that the Company did not maintain effective controls over the completeness and accuracy of internally generated reports used in the preparation of the disaggregated revenue footnote. The report used to compile revenue by major category was not reconciled to the general ledger, resulting in a misstatement of revenue by category in previously issued financial statements. While total revenue and other primary financial statement line items were not affected, the control deficiency resulted in a misstatement of a required disclosure that could have been material and was not detected by the Company's internal controls.

**(a) 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. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of the Evaluation Date, our disclosure controls and procedures were not effective due to the material weakness described below.

**(b) Management's report on internal control over financial reporting**

Management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934 as a process designed by, or under the supervision of, our principal executive and principal financial officers and effected by our Board of Directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting is defined in Rule 13a-15(f) promulgated under the Exchange Act and includes those policies and procedures that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.

Management, including the Company's Chief Executive Officer and Chief Financial Officer, does not expect that the Company's internal controls will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of internal controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Also, any evaluation of the effectiveness of controls in future periods is subject to the risk that those internal controls may become inadequate because of changes in business conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2025. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in Internal Control – Integrated Framework (2013). Based on this assessment our Chief Executive Officer and Chief Financial Officer have concluded that material weaknesses existed 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.

Subsequent to the identification of the material weakness, management has implemented 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. As of December 31, 2025, remediation efforts were ongoing. .

**EXHIBIT 19.1**

**DATA I/O CORPORATION**

**SECURITIES TRADING POLICY**

**and**

**SECURITIES LAW SUMMARY MEMORANDUM**

January 1999; updated 2005, 2007, 2012, 2019 & 2020

Data I/O Corporation (the "Company") has adopted policies and a compliance program to assist directors, officers, employees and consultants of the Company in complying with the requirements of the insider trading and short-swing profit laws. This memorandum sets forth the Company's policy on trading in the Company's securities, outlines procedures established as part of the compliance program and provides a summary of certain of your obligations under the federal securities laws.

<u>Corporate Policy Relating to Trading in the Company's Stock</u>

It is the Company's strict policy to ban: (a) trading of securities of the Company by any person while in possession of material, non-public information; (b) trading of securities of any other publicly-held company about which any such person learns non-public information through his or her relationship with the Company; (c) tipping or disclosure by any person of any material, non-public information regarding the Company or other publicly-held company if such information was acquired through such person's relationship with the Company; and (d) hedging of the Company's common stock.

"Material non-public information" is information that:

(i) could reasonably be expected to have a significant effect on the market price or value of the Company's securities; or

(ii) a reasonable investor would consider important in making an investment decision regarding the purchase or sale of the securities of the Company;

and that has not been previously disclosed or published by means of a broadly disseminated news release or securities filing with a reasonable amount of time having been given for investors to analyze the information.

Examples of material undisclosed information include but are not limited to: financial performance and significant changes in financial performance; projections and strategic plans; major corporate acquisitions and dispositions; significant changes to major assets and operations; changes in ownership of the Company's securities that may affect the control of the Company; significant changes in senior management or to the Board of Directors; significant litigation; changes in corporate structure, such as reorganizations; changes in capital structure; significant new debt or material events of default; public or private sale of additional securities; entering into or loss of significant contracts; major labor disputes or disputes with major contractors, customers or suppliers; takeover bids and issuer bids; and any decision to implement such a change by the Company's Board of Directors or by senior management who believe that confirmation of the decision by the Company's Board of Directors is probable.

If you have any doubt whether certain information is "material," you should not trade or communicate such information. Information is "non-public" until it has been made available to investors generally, such as in publicly available reports filed with the applicable stock exchange or securities commission or in press releases issued by a company. In general, information may be presumed to have been available to investors two business days after the formal release of such information.

<u>Prohibited Activities</u>

Insider Trading: You must not engage in transactions in any securities, whether of the Company or of any other public companies, while in possession of material, non-public information regarding such securities, ("insider trading").

Under this Policy, "trading" includes any sale or purchase of securities of the Company, including but not limited to: (a) hedging or monetization transactions or similar arrangements with respect to securities of the Company and (b) buying or selling puts or calls or other derivative securities on the Company's securities.

*Tipping*: You must not disclose material, non-public or other confidential information relating to the Company or other companies, when obtained in the course of service to the Company, to anyone, inside or outside of the Company (including family members) ("tipping"), except on a strict need-to-know basis as is necessary in the course of the Company's business and under circumstances that make it reasonable to believe that the information will not be misused or improperly disclosed by the recipient. You must treat all information concerning the Company as confidential and proprietary to the Company. Any uncertainty concerning the disclosure of any such information to other persons in the course of the Company's business should be im-mediately brought to the attention of the Chief Financial Officer for resolution. You must also refrain from recommending or suggesting that any person engage in transactions in securities, whether of the Company or any other company, while in possession of material, nonpublic in-formation about those securities or that company. Both the person who provides the information and the person who receives the information are liable under securities laws if the per-son who receives the information trades in securities based on the provided non-public information.

*Trading During Blackouts*: You must not, directly or indirectly, trade in securities of the Company during any blackout period.

*Hedging Transactions*: Hedging or monetization transactions can be accomplished through a number of possible mechanisms, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars and exchange funds. These transactions allow the person to continue to own the covered securities, but without the full risks and rewards of ownership. When that occurs, the person may no longer have the same objectives as the Company's other shareholders. Therefore, the Company prohibits you from engaging in such trans-actions.

Additional Policies Relating to Insiders

To facilitate compliance with the foregoing insider trading policy, and to assist officers and directors with compliance with their personal obligations under the beneficial ownership reporting requirements and short-swing profit recapture provisions of Section 16 of the Securities Exchange Act of 1934 (the "Exchange Act") and the resale procedures of Rule 144, no officer or director of the Company and certain other persons designated from time to time by the President or Chief Financial Officer ("Insiders") should purchase or sell securities of the Company without first contacting the Company's President or Chief Financial Officer. A determination will be made in each instance as to whether the Company is then in possession of material non-public information which could prohibit directors and officers from buying or selling the Company's securities. At that time, the Company can also assist the director or officer with determining whether a purchase or sale will result in a violation of the short-swing profit recapture provisions of Section 16.

Given the Company's financial reporting practices and procedures, a hold routinely will be imposed on all transactions in the Company's securities by Insiders beginning approximately 2 weeks preceding the end of each fiscal quarter and end after one full day of trading in the stock after financial results for that fiscal quarter have been publicly announced. It is the Company's practice to announce financial results during the fourth or fifth week following the end of each fiscal quarter. Accordingly, you should expect that there will be a trading hold of six or seven weeks each quarter and longer at year end due to the audit. The precise timing of these recurring hold periods may vary from period to period. In addition, other circumstances will occur from time to time requiring that there be a hold on any trading in the Company's securities by its Insiders. Accordingly, it is imperative that you strictly follow the procedure of contacting the President or Chief Financial Officer prior to making any purchase or sale of the Company's securities.

The remainder of this Memorandum is intended to familiarize you with the obligations of Insiders of public companies under the federal securities laws. In the interest of brevity, the following discussion of applicable rules and regulations has been condensed and is therefore not comprehensive. In addition, the legal requirements described are those which are currently in effect; these requirements may change from time to time. As a working guideline for action, we suggest, in any case where even the most remote doubt exists as to your personal obligations or the Company's responsibilities arising under the securities laws, that you seek further information and guidance from the Company.

I. Insider Trading Regulations.

The insider trading laws consist of several rules and regulations, including Rule 10b-5, promulgated pursuant to § 10(b) of the Exchange Act and the Insider Trading and Securities Fraud Enforcement Act of 1988 ("ITSFEA"). Those laws create corporate and personal liability in connection with (a) the purchase or sale of securities on the basis of material non-public information or (b) the disclosure of such information to another person who buys or sells securities based on it. The exposure under these laws is great; under ITSFEA, an individual who trades on or tips inside information is liable for civil penalties of up to three times the profit gained or loss avoided by the trade and criminal penalties of $ fines and jail time. Also under ITSFEA, an employer or other "controlling person" may be liable for trading on material, non-public information by employees if the corporate employer or controlling person knew or recklessly disregarded facts that would lead a reasonable person to believe that a person within its control was likely to trade on material, non-public information and failed to take appropriate steps to prevent such trading. Under these circumstances, the Company or other controlling persons may face a civil penalty of the greater of $ fines or three times the profit gained or loss avoided by the trade.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Who is an Insider for this Purpose?

An insider is anyone who has access to confidential information relating to the Company. Given their positions with the Company, directors and officers are typically deemed to have access to confidential information relating to the Company regardless of whether they have actual knowledge of such information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. What is Inside Information?

Inside information is any material information about the Company that is not available to the general public. Information is material if it would be considered important by a reasonable investor in making a decision to buy, sell or hold the security in question. The type of information most commonly found to be inside information relates to future sales, future earnings, interim financial results or acquisition negotiations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. What About Trading by Family Members?

Purchases and sales of securities by members of the immediate family or household of an insider may be deemed to be purchases and sales by the insider for purposes of the insider trading laws. Therefore, an insider and the Company could be liable for purchases or sales of securities by the insider's parents, spouse, children or other persons residing in the insider's household if such transactions are made at a time when material, non-public information is known or attributable to the insider.

Each insider is responsible for ensuring that members of his or her family and persons residing in his or her household comply with the Company's policy regarding insider trading. It is suggested that each insider closely monitor all purchases and sales of securities of the Company by such persons.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. What is the Purpose of the Company's Policy?

Most violations of the insider trading rules are inadvertent, but liability for corporate insiders can be extreme. In addition, ITSFEA places responsibility on the Company and on management as "controlling persons" to take steps to prevent violations of the insider trading laws. Thus, it is important for the Company to adopt policies and procedures to (a) prevent valued employees from making career-ending mistakes, (b) protect the Company and its key executives from controlling person liability, and (c) avoid any situation which could damage the Company's reputation for integrity and ethical conduct.

In summary, whenever any doubt exists, the presumption should be against trading in the Company's stock by any person with access to inside information until at least 48 hours after the information has been publicly announced or it is no longer material. Each individual who has access to material information must exercise the utmost caution in preserving the confidentiality of that information within the Company. If anyone becomes aware of a leak of material information, whether inadvertent or otherwise, he or she should report the situation to management immediately.

II. Section 16 Reporting Requirements; Short-Swing Profit Recapture; and Prohibition on Short Sales

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Applicability of Section 16.

Section 16 under the Exchange Act imposes certain reporting requirements and trading restrictions on the Company's directors and officers and beneficial owners of more than 10% of a class of the Company's equity securities ("10% Holders"). These persons are generally referred to herein as "Section 16 Insiders". The Section 16 rules limit the term "officer" to those officers generally considered "executive officers," including the Company's president, principal financial officer, principal accounting officer and any vice presidents in charge of a principal business unit, division or function. However, any other officer or other person who performs a significant policy-making function for the Company, who performs important executive duties, or is privy to non-public information of such character that he or she would be likely to obtain confidential information about the Company that would be useful in transactions in the Company's securities may also be considered an "officer" for Section 16 purposes. In determining whether a shareholder is a 10% Holder, they will be deemed to beneficially own all securities over which they have or share the power to vote or sell.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Reporting Requirements of Section 16(a).

Section 16 is enforced through the reporting requirements of Section 16(a). Section 16(a) requires every Section 16 Insider to report to the SEC and the Company each acquisition and disposition of shares of the Company's common stock or any other equity securities issued by the Company that are beneficially owned (as defined below) by such person, including the grant or exercise of options to purchase such securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Beneficial Ownership. Section 16 Insiders are only required to report transactions in securities that are beneficially owned by them. For purposes of determining the number of securities to report on a Section 16(a) form, Section 16 Insiders are deemed to beneficially own all securities in which they have a direct or indirect "pecuniary interest". Generally a pecuniary interest is defined as the opportunity, directly or indirectly, to profit or share in any profit derived from a transaction in the subject securities. Section 16 Insiders are presumed to have a pecuniary interest in certain specified securities, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) any "derivative securities", such as options, warrants or convertible securities, which give the Insider the right to acquire the Company's securities through their exercise or conversion, whether the derivative securities are presently exercisable or not;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Company securities held by the Insider's immediate family members who share the same household as the Insider;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) Company securities held by a trust in which the Insider has an interest; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Company securities held by a general partnership or limited partnership in which the Insider is a general partner (or limited partner which makes investments decisions), but only to the extent of such Insider's proportionate interest in the securities held by the partnership.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Reporting Forms. Section 16 provides specific forms for reporting transactions in securities. Each Section 16 Insider is responsible for the preparation and filing of his or her required reports. Three reporting forms are in effect: the initial Form 3 to be filed upon becoming a Section 16 Insider, the monthly Form 4 for certain transactions in the Company's stock, and the annual Form 5 filing for all other transactions in the Company's stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Initial Report on Form 3. A Form 3 must be filed with (and received by) the SEC within ten days after an individual (1) becomes a Section 16 Insider of the Company, whether or not such individual owns any Company stock at the time or (2) becomes a 10% Holder of the Company's stock. The individual must report on the Form 3 not only the shares of Company stock which he or she holds directly or indirectly, but also any shares of Company stock which are beneficially owned (as defined above) and held by his or her spouse, children and other members of the immediate family residing in the same household. A copy of the Form 3 must also be delivered to the Company within the same 10-day reporting period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Form 4 Report. Form 4 is used for reporting of all transactions which result in a change of beneficial ownership in the Company's securities, other than those transactions which are exempt from Section 16(b) (such as gifts and inheritances) and other transactions entitled to be reported on a deferred basis such as "small acquisitions" In addition, all grants, exercises and conversions of derivative securities (such as options granted under the Company's option plan) must be reported currently on a Form 4. A Section 16 Insider must report total beneficial ownership for each class of securities in which a transaction was reported. Stock splits and stock dividends are exempt from reporting so long as the increase or decrease in the number of securities held as a result of the split or dividend applies equally to all securities of that class. If the exercise price or amount of shares underlying a derivative security are changed as a result of a stock split or stock dividend, a Section 16 Insider may note the reason for the change in the space provided on the next filed Form 4 or Form 5 (discussed below). Form 4 must be electronically filed with (and received by) the SEC by the second day after the reportable transaction is effected. As with the Form 3, the Form 4 must also be delivered to the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) Form 5 Annual Report. Form 5 is a year-end "clean up" filing, used primarily to report transactions involving changes in beneficial ownership that are not required to be reported earlier on Form 4, either because they are exempt from Section 16(b) liability (such as gifts or inheritances) or are otherwise entitled to be reported on a deferred basis (such as "small acquisitions"). Any person who was a Section 16 Insider at any time during the fiscal year must file a Form 5 unless all transactions otherwise required to be reported on Form 5 have been previously reported on a Form 4. Section 16 Insiders must also disclose on Form 5 all transactions during the fiscal year that should have been, but were not, reported earlier on a Form 3 or Form 4 and must state their total beneficial holdings as of fiscal year end. A Form 5 must be filed by a Section 16 Insider within 45 days after the end of each fiscal year. No Form 5 filing will be required if a Section 16 Insider has reported all transactions in the Company's stock on previously filed Form 4 reports. However, the individual must provide the Company with a written representation that no Form 5 is required.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Changes in Form of Beneficial Ownership. Changes in the form of ownership (such as changes from indirect to direct ownership) which do not affect a Section 16 Insider's previously-reported pecuniary interest in the Company's securities (other than the exercise or conversion of a derivative security (such as a stock option) or the deposit into or withdrawal from a voting trust) do not need to be reported as line items on a Form 4 or Form 5. Instead, a Section 16 Insider that experiences a change in beneficial ownership should reflect the new form of beneficial ownership in the next otherwise required Form 4 or Form 5 involving the same class of equity securities which experienced the change.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Timing of Filing. As a general rule, Section 16(a) reports are considered filed only when received by the SEC in Washington, D.C. The forms must be filed electronically on EDGAR, the SEC's electronic filing system.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Short Swing Profit Liability of Section 16(b).

Section 16(b) of the Exchange Act provides that any profit realized by a Section 16 Insider on a purchase and a sale, or sale and purchase, of the Company's securities within a six-month period is recoverable by the Company. For this purpose it does not matter whether the purchase or the sale occurred first, nor is it necessary for the same shares to be involved in each of the matched transactions. In addition, losses cannot be offset against gains. Transactions are paired so as to match the lowest purchase price and the highest sales price within any six-month period, thus finding the maximum spread. For example, a sale of common stock, followed by a purchase of common stock at a lower price within six months, would result in a profit recoverable by the Company. Purchases or sales by certain related persons or entities also may be imputed to a Section 16 Insider for purposes of Section 16(b). See the discussion of "beneficial ownership" above.

Although Section 16(b) is intended to prevent the unfair use of corporate information by an insider, the restrictions and consequences of Section 16(b) apply whether or not material inside information is in fact used. Thus, it is extremely important that Section 16 Insiders review any planned purchase or sale of Company securities prior to completing the transaction to ensure that it cannot be matched with other transactions during the preceding six months or with other transactions planned within the next six months. There are a substantial number of "professional plaintiffs" who review the reports required by Section 16 described above and bring lawsuits to recover such profits, even if not pursued by the Company.

Importantly, SEC Rule 16b-3 provides, under certain limited circumstances, that the acquisition or disposition of the Company's common stock or derivative securities thereof (such as options to purchase common stock) by or from the Company will not be treated as a purchase or sale of the Company's common stock for purposes of Section 16(b) against which transactions occurring within six months can be matched (although such transactions still need to be reported under Section 16(a)). Effective August 15, 1996, Rule 16b-3 provides three methods of exempting such grants or awards by the Company to its officers and directors: (a) advance approval by the Board of Directors or a committee solely composed of two or more nonemployee directors, (b) advance approval, or substantial ratification no later than the next annual meeting, by a majority of the Company's voting security holders, and (c) holding the securities for at least six months. In the case of derivative securities, such as options, the six month period begins upon acquisition of the derivative security and will include any time the underlying securities may be held after exercise and prior to disposition. This rule exempts a wide variety of transactions that otherwise would be subject to Section 16(b). Moreover, this exemption category affords a fail-safe mechanism to Section 16 Insiders, in the form of the six-month holding period alternative, for salvaging an exemption where it is belatedly discovered that a flawed approval procedure was employed.

It should be noted, however, that if the Company is relying on the board or shareholder approval alternatives of new Rule 16b-3 as the basis for an exemption, each transaction, i.e., each grant to each recipient, must be approved (whether by the board, committee or shareholders). Thus, approval of the plan as a whole would not be sufficient, except for the approval of a formula plan (where the specific terms and conditions of each transaction are fixed in advance).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. Prohibition on "Short Sales".

Section 16(c) prohibits Section 16 Insiders from engaging in "short sales". Specifically, Section 16(c) makes it unlawful for any officer or director, directly or indirectly, to sell any equity security of the Company (other than securities exempt from Section 16(c)), if such person (1) does not own the security sold or (2) does own the security, but does not deliver it against such sale within twenty days thereafter, or does not, within five days after such sale, deposit it for delivery.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. Pre and Post Insider Transactions. Generally, transactions in Company stock that occur before a person becomes an officer or director of a public company are exempt from both the reporting and short-swing profit recovery provisions of Section 16. Many types of transactions after a person ceases to be an officer or director are, however, reportable and subject to short-swing profit recovery under Section 16 if they occur within six months of a transaction that occurred while such person was an officer or director.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. Serious Consequences for Section 16 Violations.

The Section 16 provisions are highly complex and impose serious consequences for failing to timely file required reports under Section 16(a) or engaging in transactions subject to short-swing profit recovery under Section 16(b). Such consequences include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) The Company must identify by name in its annual proxy statement and Annual Report on Form 10-K those officers and directors who failed to file any required report or who filed any delinquent report in the prior fiscal year;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) The SEC may impose monetary penalties for missing Section 16 reporting deadlines;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) Under certain circumstances, a U.S. District Court may bar a Section 16 Insider who has violated Section 16(a) from serving as a director or officer of a public company; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Officers and directors who engage in transactions subject to Section 16(b) may be required to disgorge any profits to the Company.

The Company will assist any officer or director who desires help in preparation of Forms 3, 4 and 5. Under the Company's Securities Trading Policy, directors, officers and certain designated employees are required to report in advance any transaction which may involve a change in their beneficial ownership of stock.

III. Restrictions on Sales of Shares under Rule 144.

"Controlling persons" of the Company are restricted in their sale of stock whether or not the shares themselves are "restricted." Accordingly, all sales by controlling persons of shares of the Company's common stock, whether acquired in the public market or in private transactions, must be registered by the Company under the Securities Act or made in compliance with the requirements of Rule 144. Each of the Company's officers and directors is deemed to be a "controlling person" of the Company for this purpose. Absent registration, directors and officers are required to comply with the Rule 144 requirements in any sales of securities. These requirements include (a) selling within the volume limitations of Rule 144 (i.e. sales during a period of three months may not exceed the greater of (i) one percent of the Company's outstanding shares or (ii) the average weekly trading volume in the Company's common stock for the previous four weeks), and (b) filing a Form 144 with the SEC for sales of over 500 shares or $10,000 in any three-month period. In addition, the sales must be made in "brokers transactions" or directly with a "market maker" who is subject to certain restrictions in the manner of sale. Therefore, be sure to advise your broker of your relationship with the Company whenever effecting trades in the Company's stock. Bear in mind that compliance with Rule 144 is not a substitute for compliance with the insider trading laws or the short-swing profit provisions of Section 16 of the Exchange Act. Thus, an exempt sale under Rule 144 may result in a short-swing profit recoverable by the Company (or any shareholder on behalf of the Company) under Section 16(b) if the sale occurs within six months before or after the seller's purchase of Company stock at a lower price.

IV. Special Requirements for More-Than-Five-Percent-Shareholders

In addition to the requirements discussed above, shareholders who beneficially own more than five percent of the Company's common stock are subject to special reporting requirements discussed in Appendix B attached to this Memorandum.

**<u>APPENDIX A</u>**

**<u>SECURITIES TRANSACTION CHECKLIST</u>**

**SALES**: If a director, officer or 10% Holder (or any member of his or her immediate family) proposes to effect a sale Section 16 and Rule 144 pose the following considerations:

Section 16 Considerations:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Have there been any purchases by the Insider (or a member of his or her immediate family) within the past six months?

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. If the shares to be sold were acquired upon the exercise of an option, was the option granted more than six months ago?

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Are any purchases (including non-exempt acquisitions of shares or options under employee benefit plans) anticipated within the next six months?

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. Has the person responsible for preparing the Form 4 been advised?

*Rule 144 Considerations:*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. Is the amount of shares to be sold (together with all sales in the previous 3 months) less than the greater of (a) one percent of the Company's outstanding shares or (b) the average weekly trading volume in the Company's common stock for the previous four weeks?

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. Is the broker effecting the sale aware of the Insider's status as an affiliate?

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. Are more than 500 shares or shares valued at $10,000 or more being sold? If so, has a Form 144 been prepared?

**PURCHASES**: If an insider proposes to effect a purchase (other than the exercise of an in-the-money option) Section 16 poses the following considerations:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Have there been any sales by the insider (or a member of his or her immediate family) within the past six months?

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Are any sales anticipated within the next six months (such as tax-related or year-end transactions)?

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Has the person responsible for preparing the Form 4 been advised?

**OPTION EXERCISES**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. If any of the option shares are to be sold immediately, was the option granted in compliance with Rule 16b-3?

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Has the person responsible for preparing the Form 4 been advised?

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Is the sale in compliance with Rule 144 (See "Rule 144 Considerations" above)?

**NOTE**: IN ADDITION TO THE ABOVE, ALL TRANSACTIONS MUST COMPLY WITH THE COMPANY'S SECURITIES TRADING POLICY. BEFORE PROCEEDING WITH A PURCHASE OR SALE, CONSIDER WHETHER YOU ARE AWARE OF MATERIAL INSIDE INFORMATION THAT COULD AFFECT THE PRICE OF THE STOCK.

**<u>APPENDIX B</u>**

**<u>FILING REQUIREMENTS FOR MORE THAN FIVE-PERCENT SHAREHOLDERS</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. <u>What special requirements apply to more-than-five-percent Shareholders?</u> When a shareholder is a beneficial owner of more than five percent of the Company's stock, he or she is required to disclose certain information to the SEC by filing either a Schedule 13D or Schedule 13G. For purposes of determining if a shareholder holds more than five percent of the Company's stock, a person is deemed to own any securities which he or she has or shares the power to vote or to sell. Certain shares under options, as well as shares held by certain family members, partnerships, corporations, or trusts are included. Generally, acquisitions (a) before a company's initial public offering, or (b) of less than twenty percent of a class of stock which is not made for the purpose of changing or influencing control of the Company, may be reported on Schedule 13G.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. <u>What information is included in Schedule 13D and Schedule 13G?</u> Disclosures required under Schedule 13G are less intense than Schedule 13D. Each schedule requires disclosure of the identity and background of the reporting person, the class of securities reported on, the percentage of beneficial ownership and the number of shares owned. In addition, Schedule 13D requires information about the source and amount of funds used to purchase the stock, the purpose of the acquisition and any understanding or other relationships between the reporting person and the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. <u>When must a Schedule 13D or Schedule 13G be filed?</u> If a shareholder is obligated to file a Schedule 13D, it must be filed within ten days after the purchase that triggers the obligation to file. Amendments to Schedule 13D reporting material changes in an earlier report must be filed "promptly"; filing an amendment within a day or two following the triggering event is generally advisable.

A Schedule 13G and any amendments generally must be filed within 45 days after the calendar year in which the obligation to file the Schedule 13G or the amendment arose. However, if a person is eligible to file Schedule 13G because they hold less than twenty percent of a class of securities, that Schedule 13G must be filed within ten days of the purchase triggering the obligation to file. In addition, a person who filed a Schedule 13G under such circumstances must file an amendment on Schedule 13G "promptly" upon acquiring ten percent of a class of stock and upon increasing or decreasing its holdings by more than five percent of such class. In addition, such person must file a Schedule 13D within ten days if they (i) have acquired securities for the purpose of changing or influencing control of the Company or (ii) hold more than twenty percent of the class. Both Schedule 13Ds and Schedule 13Gs must now be filed electronically via EDGAR. In order for an individual to file via EDGAR, he or she must first obtain an EDGAR identification number by submitting a written application to the SEC. In addition, both the Company and the filer must retain executed originals of the Schedule 13D or Schedule 13G for at least five years from the date of filing.
