2024 ANNUAL REPORT 
& PROXY STATEMENT
Unified Programming Platform Supporting Design to Production and Beyond
Letter to Shareholders
2024 Annual Report on Form 10-K
Notice of 2025 Annual Meeting 
& Proxy Statement 

 

 
 
 
April 2, 2025 
 
Dear Data I/O Shareholders: 
 
During 2024, Data I/O experienced lower demand for manufacturing capacity and spending on capital equipment, 
particularly in the automotive segment where we have a strong vertical domain concentration. This decrease in 
demand is principally attributed to headwinds faced by electric vehicle (“EV”) manufacturers in Europe and the 
Americas, partially offset by a strong EV market in Asia which is expected to continue to grow. This dichotomy 
reinforces the need to diversify our customers across multiple market verticals.  
 
The most significant development in 2024, however, was a change to our executive leadership. We have streamlined 
the leadership team and have been aligning our global workforce with our strategic initiatives. In 2025, we began 
setting our sights on a much larger market and focusing on delivering greater value to a diversified base of customers 
that includes some of the largest companies throughout the global electronics supply chain. 
 
We have hired proven industry veterans, promoted from within and created new positions. New and existing team 
members along with invited thought leaders have been deeply involved in discovery within every functional group at 
Data I/O. This discovery process has led to the implementation of crucial strategic plans to bring Data I/O back to 
long term profitable growth. We have a new focus on the global distribution, EMS, and service provider customer 
segments, and are intent on continued investment in delivering solutions to support our customers and accelerate 
their time to market. As part of this approach, we anticipate a heightened presence in a cross section of customer 
spending on products and services, from initial device design to scaling commercial production. We will continue to 
support strong solutions for the automotive industry as well as expand our market reach in IoT, consumer, 
aerospace/defense, and medical. We will re-engage with our semiconductor partners to deepen our relationships and 
develop programming solutions for new device technologies driven by advancements in AI and edge computing 
applications for the automotive, IoT, medical, industrial and consumer applications. We will also look for ways to 
leverage AI to scale operations to meet this market demand. This will enable Data I/O to keep pace with rapid 
changes in the market. These are the steps we believe are necessary to become a higher value partner with a 
broader reach into the global electronics supply chain. 
 
Over the years, the programming vendor ecosystem has been focused on large automated systems. That focus takes 
away from developing a robust library of device algorithms needed to support a variety of customer applications and 
market segments. The next generation universal programming platform, manual programming products, and our new 
consultative sales process will be instrumental in our long-term organic growth across these market segments. Our 
engineering team is enhancing our current Lumen®X platform while creating an impressive roadmap for the future. 
With a legacy in the programming industry spanning more than 50 years, the Data I/O brand still resonates today. 
What we are doing now through investments in our platform, our processes and our workforce is expected to create a 
more efficient and effective organization. We made impressive progress on these initiatives in the first quarter of 2025 
and intend to continue on this path throughout the year.   
 
We appreciate your continued support of Data I/O. 
 
 
Sincerely, 
 
 
 
William Wentworth, CEO  
 
 
Sally Washlow, Chair

PART I 
 
Item 1.  Business 
 
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.  Most electronic products today incorporate a number of programmable 
semiconductor devices that contain data, operating instructions and security credentials essential for the proper operation of the 
product and more and more products require security deployment. 
 
Our mission is to bring the world’s electronic devices to life.  Programmable devices are used in products such as automobile 
electronics, smartphones, HDTV, smart meters, gaming systems and a broad category called Internet of Things (“IoT”).  IoT is a 
broad term that addresses the interconnectivity of devices and other electronic or smart products.  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.  Our largest customers are 
heavy users of programmable semiconductor devices and include original equipment manufacturers (“OEMs”) and tier 1 suppliers 
in automotive electronics, industrial electronics, consumer electronics and IoT markets as well as their programming center 
partners and electronic manufacturing service (“EMS”) contract manufacturers. 
 
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 2024 
 
Due to economic and automotive electronics uncertainties and slower customer capacity expansion, shipments of the Company’s 
automated systems in the Americas and Europe were lower which was partially offset by revenue growth in Asia.  COVID-19 
impacts in past years were no longer an operational challenge with personnel staffing, inventory levels, supply chain and 
operational activities returning to normal levels.  However, late in 2024 with the new incoming United States Administration, geo-
political, economic and trade uncertainties have increased.  The resulting future impact on the Company’s markets, customers, 
supply chain and operations are uncertain.  We will leverage the experience gained from the impacts of COVID-19, along with the 
expertise of our leadership and operational teams, to effectively navigate and mitigate these potential challenges. 
 
After a period of stability which lasted over a decade, a key organizational leadership transition occurred in the fourth quarter of 
2024 with the planned retirement of Anthony Ambrose and the appointment of a new CEO and President, William Wentworth.  
Subsequent changes have also occurred in the leadership of the Sales, Marketing and Engineering functions. 
 
Industry Background 
 
We enable 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 installation and repair, and device programming.  Companies that design and manufacture products 
utilizing programmable electronic devices, ranging from automobiles to cell phones, 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.   

4 
10-K 
Traditionally, our programming market opportunity focused on the number of semiconductor devices to be programmed, but 
because of the rapid increase in the density of devices, and increasing demands for supply-chain security, the focus has shifted in 
many cases, from the number and type of devices to the number and type of bits per device to be programmed or securely 
provisioned.  With expected growth in IoT applications, the business opportunity for this market differs depending on quality, 
security and automation. 
 
Some of our automated programming systems integrate data programming, automated handling functions and/or security 
deployment into a single product solution. Quality and security-conscious customers, particularly those in high-volume 
manufacturing and programming, drive this portion of our business.  
 
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.  Our newer products are positioned and recognized as some of the most advanced 
programming and security deployment solutions.  
 
Our programming solutions include a broad range of products, systems, modules and accessories, grouped into two general 
categories: automated programming systems and manual programming systems.  Our PSV family of automated programming 
systems delivers a broad range of programming capacity and capability to the marketplace.  Our PSV2800 Automated Programming 
System focuses on dedicated high-volume manufacturing in a lower cost platform.  Our PSV7000 Automated Programming System 
continues to be well adopted in the marketplace, in particular for automotive electronics customers and as a base for security 
deployment upgrades.  Our PSV5000 Automated Programming System combines mid-range capacity and flexibility with 
competitive pricing and also supports security deployment.  Our PSV3500 Automated Programming System is a lower cost platform 
for basic programming needs.  Our PSV family of handlers has won multiple industry awards for technical excellence and innovation 
and has a large global installed base.   
 
Our automated systems have list selling prices ranging from approximately $62,000 to $690,000 and our manual systems have list 
selling prices ranging from approximately $10,000 to $20,000.  Our security deployment system, SentriX®, is offered as a software 
license added to existing programming systems or on a pay per part use basis along with related fees. 
 
Data I/O programming technology is integrated with the PSV family to create highly-flexible systems that deliver outstanding 
performance with low total cost of ownership. The Lumen®X programming engine is our highest performance programming 
engine, designed to support eMMC and UFS programming of large NAND FLASH, as well as microcontrollers, serial FLASH and other 
devices.  Increasing memory densities and the need for faster data interfaces are resulting in an expected transition to the use of 
UFS devices.  LumenX is available on our PSV7000 and PSV5000 and as a standalone manual programmer.  FlashCORE™, and our 
universal job setup tool, Tasklink™ for Windows®, are available in each family of our automated programming systems and in 
FlashPAK™, our manual programming system.  The SentriX security system adds security capability to our data programming 
system.  SentriX allows customers of any size and demand-profile to securely add keys, certificates, and other security information 
to specialized regions of authentication integrated circuits ("ICs”), secure elements and secure microcontrollers.  We provide device 
support and service on all of our products.  Device support is a critical aspect of our business and consists of writing software 
algorithms for devices and developing socket adapters to hold and connect to the device for programming.

Our solutions address the data programming and security deployment needs of programmable semiconductor devices.  
Semiconductor devices are a large, growing market, in terms of units, bits programmed and need for security.  We believe that our 
sales are driven by many of the same forces that propel the semiconductor industry as well as the automotive electronics industry.  
We sell to the manufacturers who are consumers of certain semiconductors.  When their business grows, they buy more 
semiconductors which, in turn, require additional programming equipment to maintain production speeds or program new device 
technologies. 
 
Our device programming solutions currently target two high volume growing markets: automotive electronics and IoT systems, 
including industrial and consumer devices.

representatives operating in 32 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 2024, 2023 and 2022 were (in millions) $20.4, $25.3 and $22.4, 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 information covering the programming systems or security deployment 
market, according to our internal analysis of competitors’ revenues, we believe we continue to be the largest supplier 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) $3.5, $2.8 and $4.8 as of December 31, 2024, 2023 and 2022, 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 2024, 2023 and 2022, we made expenditures for research and development of (in millions) $6.2, $6.5 and $6.1, respectively, 
representing 29%, 23% and 25% of net sales, respectively.  Research and development costs are generally expensed as incurred. 
 
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, 2024, we were not subject to any pending actions regarding infringement claims. 
 
Employees - Human Capital 
 
As of December 31, 2024, we had a total of 95 employees, of which 45 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.  
 
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 

10 
10-K 
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.    
 
As the largest and only publicly traded company in its sector, according to our internal analysis, Data I/O has led its industry in 
disclosing significant operational and financial information.  The Company's Board currently includes Data I/O's CEO and four 
Independent Directors.  It is diverse in gender, education, professional experience and differences in viewpoints and skills.  Through 
its continuous improvement practices and our operations’ focus on assembly and test with no fabrication, the Company consumes 
relatively little energy, has minimal or no emissions or pollutants to air and wastewater, and complies with workplace labor, safety 
and business practices on three continents. Additionally, the Company started to purchase only sustainable (green) electric power 
(in our China & U.S. facilities in 2023; German facility in prior years) and started to purchase offsets for its carbon emissions from 
natural gas use in the U.S. facility. For our vehicles, we have been replacing company-owned cars with hybrid or electric vehicles 
where feasible.  None of these actions have had a material financial impact. Recent developments to climate regulations and 
guidelines have increased customer demands for climate disclosures on their timelines as opposed to regulations applicability to 
the Company. 
 
Data I/O is also committed to giving back to our local communities through volunteer and internship programs.  The Company 
provide employees time-off to volunteer.  In addition, the Company provides internships to local high school and college students 
through STEM and technical colleges.   
 
Compliance with environmental laws has not had, nor is it currently expected to have, a material effect on our capital expenditures, 
financial position, results of operations or competitive position. Potential regulations regarding climate change measurements and 
disclosures could require significant effort and costs.

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, 

11 
10-K 
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 
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 trade issues may adversely affect our business, including revenues and/or gross margins. 
 
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 Israel - Hamas war could have similar 
issues, although we have not experienced any material impacts. 
 
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, for example in security deployment of programmable 
devices, circuit boards and electronic systems, 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 security deployment 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. 
 
In the security deployment area, we have introduced a pay per use business model and service fees that may not be accepted by 
our customers who are accustomed to paying for capital equipment upfront, rather than paying per use charges. 
 
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:   

12 
10-K 
• 
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 programing 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 and our orders related to automotive electronics customers has been dominant in recent 
years at 59% in 2024, 63% in 2023 and 61% in 2022.  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 and/or security deployment systems or the robotics for new 
automated handing 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; 

13 
10-K 
• 
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. 
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. 
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 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. 
 
 

14 
10-K 
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 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. 
Current and future public health crise, 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. 

15 
10-K 
Our international operations may expose us to additional risks that may adversely affect our business. 
International sales represented approximately 94%, 90% and 93% of net sales in 2024, 2023 and 2022, 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; 

16 
10-K 
• 
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; 
• 
timing of installation or customer acceptance requirements; 
• 
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 five 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. 
 
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. 
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 

17 
10-K 
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 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 which we believe, we are in 
compliance with.  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. Unfortunately, 
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) 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, 2024.  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.   

18 
10-K 
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

Item 1C. Cybersecurity 
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; however, the full Board is typically present for 
Information Technology (IT) and Cybersecurity briefings.  As part of its oversight role, the Audit Committee receives reporting 
about the Company’s cybersecurity program, activities, threats and incidents (if any) through periodic updates.  The cybersecurity 
program is managed by our outsourced IT infrastructure team with oversight and coordination by our CFO, who reports directly to 
our CEO.  Utilization of an outsourced IT infrastructure team allows Data I/O to access the necessary breadth and depth of leading 
cybersecurity programs, staff, expertise, and tools.  The IT infrastructure team monitors the prevention, mitigation, detection, and 
remediation of cybersecurity incidents through their management of the cybersecurity function, including the operation of the 
Company’s incident response plans, which include appropriate escalation to the CFO, CEO and the Audit Committee. 
 
CYBERSECURITY RISK MANAGEMENT AND STRATEGY 
The Company has processes in place to identify, assess, and monitor material risks from cybersecurity threats, which are part of 
the Company’s overall cybersecurity risk management and have been embedded in the information systems operating procedures 
and internal controls.  Our IT function manages IT operations and continually evolves and enhances our systems to meet the 
constantly changing digital environment.  Periodic cybersecurity risk assessments are performed to identify, assess, and prioritize 
potential risks to information, data assets, infrastructure and third-party vendors.  The Company addresses significant risks through 
corrective or mitigating actions as necessary. 
The Company has also established cybersecurity and information security awareness training programs. Employees with access to 
the Company’s network receive annual training on topics such as phishing, malware, and other cybersecurity risks.  Training is 
administered and tracked through online learning modules with ongoing follow-up testing.  All employees and contractors enter 
into non-disclosure confidentiality agreements.  We work to continually evolve our systems to meet the constantly changing digital 
environment and continue to invest in the cybersecurity and resiliency of our networks and to enhance our internal controls and 
processes, which are designed to help protect our systems and infrastructure, and the information they contain.

There have been no risks from cybersecurity threats that have materially affected or are reasonably likely to materially affect our 
business strategy, results of operations or financial condition. The nature of potential cybersecurity risks and threats are uncertain, 
and any future incidents, outages or breaches could have a material adverse effect on the Company’s business, financial conditions 
or results of operations. For more information about the cybersecurity risks we face, refer to the Risk Factors in section 
“Cybersecurity Risks” in Part I, Item 1A, "Risk Factors". 
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 2024 and 2023 were approximately 
$795,000 and $823,000, 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, 2024, 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  
  
The automotive and industrial electronics industry is cyclical.  With increased market uncertainty and customer capacity expansion 
slowing in 2024, automated systems shipments declined in the Americas and Europe which was partially offset by revenue growth 
in Asia. Automotive electronics represented 59% of 2024 bookings compared to 63% for 2023.  While automotive system sales 
were below expectations, the Company continues to expand its sales to service providers (franchise distribution, contract 
manufacturers and independent providers) and reoccurring revenue offerings.  For the full year, consumable adapters and services 
revenue remained steady, representing 50% of total revenue and helping mitigate the decline in system sales. 
 
COVID-19 impacts in past years were no longer an operational challenge with personnel staffing, inventory levels and supply chain 
and operational activities returning to normal levels.  However late in 2024 with the new incoming United States Administration, 
geo-political, economic and trade uncertainties have increased.  The resulting future impact on the Company’s markets, customers, 
supply chain and operations are uncertain.  However, the operational and manufacturing resiliencies gained from the COVID-19 
impact and the experience of leadership and operational teams can be leveraged to navigate and mitigate these potential future 
challenges.  As our customers shift their supply chain and manufacturing locations to address changing economic and trade 
constraints, we will have the capacity and ability to adjust accordingly. 
 
After a period of stability which lasted over a decade, key organizational leadership transition occurred in the fourth quarter of 
2024 with the appointment of a new CEO and President, William Wentworth.  Subsequent changes have also occurred in the 
leadership of the Sales, Marketing and Engineering functions and corresponding changes in the strategic and operational direction 
of these groups.  We believe these changes will drive improved revenue growth, higher product innovation, greater operational 
efficiency and improved financial performance. 
 
We continue to make investments in technologies, products and services to maintain market leadership in our Unified 
Programming Strategy.  This strategy supports our customers’ preprogramming supply chain needs, from design to manufacturing 
and beyond.  Our manual programmer offerings, such as LumenX and FlashCore, provide preprogramming solutions for our 
customers’ design, engineering, new product introduction, low-to-medium production, and test needs while our PSV system of 
products support medium-to-high volume production needs.  Our strong cash position and balance sheet, combined with our long-
term view of the market, gives us financial flexibility to make these investments. 
 
CRITICAL ACCOUNTING POLICY JUDGMENTS AND ESTIMATES 
 
The preparation of financial statements in accordance with accounting principles generally accepted in the United States of 
America requires that we make estimates and judgments, which affect the reported amounts of assets, liabilities, revenues and 
expenses, and related disclosures of contingent assets and liabilities.  On an on-going basis, we evaluate our estimates, including 
those related to revenue recognition, sales returns, credit losses, inventories, income taxes, warranty obligations, restructuring 
charges, contingencies such as litigation and contract terms that have multiple elements and other complexities typical in the 
capital equipment industry.  We base our estimates on historical experience and other assumptions that we believe are reasonable 
under the circumstances.  Actual results may differ from these estimates under different assumptions or conditions.   
 
We believe the following critical accounting policies affect the more significant judgments and estimates used in the preparation 
of our financial statements:  
 
Revenue Recognition: Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers (ASC 606) 
provides a single, principles-based five-step model to be applied to all contracts with customers.  It generally provides for the 
recognition of revenue in an amount that reflects the consideration to which the Company expects to be entitled, net of allowances 

21 
10-K 
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 2024 and 2023, 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 and that the installation meets the criteria to be a separate performance obligation.  These systems are standard 
products with published product specifications and are configurable with standard options.  The evidence that these systems could 
be deemed accepted was based upon having standardized factory production of the units, results from batteries of tests of product 
performance to our published specifications, quality inspections and installation standardization, as well as past product operation 
validation with the customer and the history provided by our installed base of products upon which the current versions were 
based. 
 
The revenue related to products requiring installation, that is perfunctory, is recognized upon transfer of control of the product to 
customers, which generally is at the time of shipment.  Installation that is considered perfunctory includes any installation that is 
expected to be performed by other parties, such as distributors, other vendors, or the customers themselves.  This analysis 
considers the complexity, skill and training needed, as well as customer expectations regarding installation. 
 
We enter into arrangements with multiple performance obligations that arise during the sale of a system that could include 
hardware, software, installation, service and support, and extended maintenance components.  We allocate the transaction price 
of each element based on the relative selling prices.   Relative selling price is based on the selling price of the standalone system.  
For the installation and service and support performance obligations, we use the value of the discount given to distributors who 
perform these components.  For software maintenance performance obligations, we use what we charge for annual software 
maintenance renewals after the initial year the system is sold.  Revenue is recognized on the system based on shipping terms, 
software based on delivery, installation and services based on completion of work and software maintenance and extended 
warranty support ratably over the term of the agreement, typically one year. 
 
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-

22 
10-K 
by-item basis and record inventory adjustments accordingly.  If there is a significant decrease in demand for our products, 
uncertainty during product line transitions, or a higher risk of inventory obsolescence because of rapidly changing technology and 
customer requirements, we may be required to increase our inventory adjustments, and our gross margin could be adversely 
affected.   
 
Warranty Accruals:  We accrue for warranty costs based on the expected material and labor costs to fulfill our warranty obligations.  
If we experience an increase in warranty claims, which are higher than our historical experience, our gross margin could be 
adversely affected.   
 
Tax Valuation Allowances:  Given the uncertainty created by our loss history capital and geographic spending, as well as income 
and current net deferred tax assets by entity and country, we expect to continue to limit the recognition of net deferred tax assets 
and accounting for uncertain tax positions and maintain the tax valuation allowances.  At the current time, we expect, therefore, 
that reversals of the tax valuation allowance will take place as we are able to take advantage of the underlying tax loss or other 
attributes in carry forward or their use by future income or circumstances allow us to realize these attributes.  The transfer pricing 
and expense or cost sharing arrangements are complex areas where judgments, such as the determination of arms-length 
arrangements, can be subject to challenges by different tax jurisdictions.   
 
Share-based Compensation: We account for share-based awards 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.

Net sales for the year ended December 31, 2024 decreased approximately 22%, to $21.8 million, compared to 2023.  In 2024, 
automotive electronics uncertainty persisted and customer capacity expansion slowed, resulting in lower system shipments in the 
Americas and Europe which were partially offset by growth in Asia.  Automotive electronics represented 59% of 2024 bookings 
compared to 63% for 2023.  While automotive system sales were below expectations, the Company continues to expand its sales 
to service providers (franchise distribution, contract manufacturers and independent providers) and reoccurring revenue offerings.  
For the full year, consumable adapters and services revenue remained steady, representing 50% of total revenue and helping 
mitigate the decline in system sales.   
 
Order bookings were $22.5 million in 2024, down approximately 12.6% compared to $25.8 million in 2023 due to similar market 
challenges noted for revenue.  The order backlog on December 31, 2024, was $3.5 million, up $0.7 million from the fourth quarter 
of 2023, which will benefit revenue recognition in the first half of 2025 as systems are shipped.  Additionally, deferred revenue 
was approximately $1.6 million on December 31, 2024.

Gross margin as a percentage of sales for the year ended December 31, 2024, was 53.3%, compared to 57.7% in 2023.  The decrease 
in gross margin as a percentage of sales primarily reflects lower sales volume and lower related absorption of fixed manufacturing 
and service operating costs.  Actual 2024 production and service spending decreased by $250,000 or 4% from the prior year.

We believe it is essential to invest in R&D to significantly enhance our existing solutions and create new products as markets 
develop and technologies change.  During 2024, 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 decreased approximately $810,000 thousand for the year ended December 
31, 2024 compared to 2023.  The decrease was primarily related to lower sales commissions on lower revenue and lower outside 
services from efficiency improvements and cost controls. Cost control measures remain in effect.  Salary and wages remained flat 
with lower headcount savings offset by staff separation charges of approximately $430,000 in the fourth quarter of 2024.

($194) 
  
Income tax (expense) increased by $192,000 for the year ended December 31, 2024 compared to 2023.  The increase was primarily 
a result of the withholding tax of $337,000 on the repatriation of cash from China subsidiary in 2024.  Income tax (expense) in 2024 
and 2023 is primarily the result of foreign subsidiary income tax and minimal U.S. state income tax. 
The effective tax rate for 2024 of (14.3%) and 2023 of 28.6% differed from the statutory tax rates in our tax reporting jurisdictions 
primarily due to subsidiary income with consolidated losses and the effect of valuation allowances.  We have a valuation allowance 
of $8.2 million and $8.7 million as of December 31, 2024 and 2023, respectively.  Our deferred tax assets and valuation allowance 
have increased by approximately $442,000 and $430,000 associated with the requirements of accounting for uncertain tax 
positions as of December 31, 2024 and 2023, respectively.  Given the uncertainty created by our loss history, particularly in the 
U.S., which is where most of our net deferred tax assets are located, and the ongoing uncertain economic outlook for our industry, 
as well as capital and geographic spending, we currently expect to continue to limit the recognition of net deferred tax assets and 
maintain the tax valuation allowances. 
 
INFLATION AND CHANGES IN FOREIGN CURRENCY EXCHANGE RATES 
 
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.  We recognized foreign currency transaction gains of $58,000 in 2024 
and $42,000 in 2023.  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.

Working capital

($2,340) 
$18,425  
 
At December 31, 2024, our principal sources of liquidity consisted of existing cash and cash equivalents.  Cash at December 31, 
2024 and 2023 was $10.3 million and $12.3 million, respectively.  Working capital decreased by $2.3 million during 2024 due 
primarily to the revenue decline and resulting operating loss. Our current ratio improved and was 4.2 and 4.0 for December 31, 
2024 and 2023, respectively.  The company continues to have no debt. 
 
Although we have no significant external capital expenditure plans currently, 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 our cyclical and seasonal industry, significant product development, factory resilience strategies, customer support 
and selling and marketing efforts, we require substantial working capital to fund our operations.  We have implemented or have 
initiatives to implement geographic shifts in our operations, optimize real estate usage, adjust pricing for cost inflation, lower unit 
costs, lower tariff expenses, reduce exposure to the impact of currency volatility, increase product development differentiation, 
and reduce other costs.  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, 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. In the second quarter of 2024, we completed a $3.4 million dividend distribution from our China subsidiary 
operation, incurring a $337,000 foreign tax withholding expense.  This was undertaken to optimize the cash position and operating 
needs of each subsidiary, increase the interest earning potential of our cash holdings and ensure available liquidity at the U.S. 
headquarters to support future strategic and operational initiatives. 
 
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.

NEW ACCOUNTING PRONOUNCEMENTS - STANDARDS ISSUED AND IMPLEMENTED 
 
Effective January 1, 2024, the Company adopted ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable 
Segment Disclosures. This update requires entities, including those with a single reportable segment, to disclose significant 
segment expenses regularly provided to the Chief Operating Decision Maker (CODM) and included in the reported measure of 
segment profit or loss. 
 
The Company operates as a single reportable segment. The CODM evaluates the Company's performance based on operating 
income, as presented in the consolidated statements of operations. Significant segment expenses are those that are already 
disclosed in operating income and regularly reviewed by the CODM for purposes of assessing performance and allocating 
resources.  Additional significant single segment expense categories are provided in Note 13 – Segment Information. 
 
NEW ACCOUNTING PRONOUNCEMENTS - STANDARDS ISSUED AND NOT YET IMPLEMENTED  
 
In December 2023, the FASB issued ASU 2023-09 "Income Taxes (Topics 740): Improvements to Income Tax Disclosures" to expand 
the disclosure requirements for income taxes, specifically related to the rate reconciliation and income taxes paid. ASU 2023-09 is 
effective for our annual periods beginning January 1, 2025, with early adoption permitted. We are currently evaluating the 
potential effect that the updated standard will have on our financial statement disclosures. 
 
In November 2024, FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation 
(Subtopic 220-40), which requires disclosure of specific information about costs and expenses within relevant expense captions on 
the face of the income statement, qualitative descriptions for expense captions not specifically disaggregated quantitatively, and 
the total amount and definition of selling expenses for interim and annual reporting periods.  This standard is effective for the 
annual reporting period beginning January 1, 2027 and interim reporting periods beginning January 1, 2028 and should be applied 
retrospectively to all comparative periods.  Early adoption is permitted.  The Company is currently evaluating the effects of 
adopting this new accounting guidance.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 
 
 
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, 2024 and 2023, 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, 
2024, and the related notes and financial statement schedules included under Item 15(a)(2) (collectively referred to as the 
“financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the 
Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the two years in the 
period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America. 
 
Basis for opinion  
 
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the 
Company’s 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. 
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.  

28 
10-K 
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.

manufacturers of electronic products.  Our programming system products are used to program integrated circuits (“ICs” or 
“devices” or “semiconductors”) with the specific unique data necessary for the ICs contained in various products and are an 
important tool for the electronics industry experiencing growing use of programmable ICs.  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 $4.3 and $6.6 million at December 31, 2024 and 2023, 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.

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.  If the total of future undiscounted cash flows is less than the carrying amount of these 
assets, an impairment loss, if any, based on the excess of the carrying amount over the fair value of the assets, is recorded.  Based 
on these evaluations, for the years ended December 31, 2024 and 2023, 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.  
 
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 2024 and 2023, 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 and that the installation meets the criteria to be a separate performance obligation.  These systems are standard 
products with published product specifications and are configurable with standard options.  The evidence that these systems could 
be deemed accepted was based upon having standardized factory production of the units, results from batteries of tests of product 
performance to our published specifications, quality inspections and installation standardization, as well as past product operation 
validation with the customer and the history provided by our installed base of products upon which the current versions were 
based. 
 
The revenue related to products requiring installation, that is perfunctory, is recognized upon transfer of control of the product to 
customers, which generally is at the time of shipment.  Installation that is considered perfunctory includes any installation that is 
expected to be performed by other parties, such as distributors, other vendors, or the customers themselves.  This analysis 
considers the complexity, skill and training needed as well as customer expectations regarding installation. 
 
We enter into arrangements with multiple performance obligations that arise during the sale of a system that could include 
hardware, software, installation, services and support and extended maintenance components.  We allocate the transaction price 
of each element based on the relative selling prices.  Relative selling price is based on the selling price of the standalone system.  
For the installation and service and support performance obligations, we use the value of the discount given to distributors who 
perform these components.  For software maintenance performance obligations, we use what we charge for annual software 
maintenance renewals after the initial year the system is sold.  Revenue is recognized on the system based on shipping terms, 
software based on delivery, installation and services based on completion of work and software maintenance and extended 
warranty support ratably over the term of the agreement, typically one year.  Total deferred revenue which represents undelivered 
performance obligations for installation, service, support and extended maintenance contracts was $1.7 million and $1.6 million 
and the portion expected to be recognized within one year was $1.5 million and $1.4 million for December 31, 2024 and 2023, 
respectively. 
 
When we sell 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.

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, 2024, 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. 
For example, 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-cancelable 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 $92,000 and $196,000 in 2024 and 
2023, respectively. 
 

38 
10-K 
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 74,000 and 133,000 for the years 
ended December 31, 2024 and 2023, respectively.  Excluded from the computation of diluted earnings per share were options to 
purchase 200,000 and 12,500 shares of common stock because of the loss in 2024 and options’ purchase price exceeding market 
price (underwater) in 2023, thus the options were anti-dilutive for the years ended December 31, 2024 and 2023, 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, 2024 and 2023 includes foreign accounts receivable in the functional currency of our foreign 
subsidiaries amounting to $1.2 and $1.0 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.

New Accounting Pronouncements - Standards Issued and Implemented 
 
Effective January 1, 2024, the Company adopted ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable 
Segment Disclosures. This update requires entities, including those with a single reportable segment, to disclose significant 
segment expenses regularly provided to the Chief Operating Decision Maker (CODM) and included in the reported measure of 
segment profit or loss. 
 
The Company operates as a single reportable segment. The CODM evaluates the Company's performance based on operating 
income, as presented in the consolidated statements of operations. Significant segment expenses are those that are already 
disclosed in operating income and regularly reviewed by the CODM for purposes of assessing performance and allocating 
resources.  Additional significant single segment expense categories are provided in Note 13 – Segment Information. 
 
New Accounting Pronouncements - Standards Issued and Not Yet Implemented 
 
In December 2023, the FASB issued ASU 2023-09 "Income Taxes (Topics 740): Improvements to Income Tax Disclosures" to expand 
the disclosure requirements for income taxes, specifically related to the rate reconciliation and income taxes paid. ASU 2023-09 is 
effective for our annual periods beginning January 1, 2025, with early adoption permitted. We are currently evaluating the 
potential effect that the updated standard will have on our financial statement disclosures. 
 
In November 2024, FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation 
(Subtopic 220-40), which requires disclosure of specific information about costs and expenses within relevant expense captions on 
the face of the income statement, qualitative descriptions for expense captions not specifically disaggregated quantitatively, and 
the total amount and definition of selling expenses for interim and annual reporting periods.  This standard is effective for the 
annual reporting period beginning January 1, 2027 and interim reporting periods beginning January 1, 2028 and should be applied 
retrospectively to all comparative periods.  Early adoption is permitted.  The Company is currently evaluating the effects of 
adopting this new accounting guidance.

Payments for operating lease liabilities for the twelve months ending December 31, 2024 and 2023, respectively, were $833,000 
and $894,000 which included short-term lease costs of $38,000 and $25,000.  The total annual lease expense in 2024 and 2023, 
including operating lease expenses and short-term lease expenses, was approximately $845,000 and $745,000, respectively.  
Variable payments were not material and were treated as non-lease components and were recognized in the period for which the 
costs occur. 
 
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 total annual gross or base lease payments during 
2024 and 2023 were approximately $795,000 and $823,000, 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.

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, 2024, we had four contracts with a commitment of approximately $389,000 to be paid in 2025 and $1,630,000 
to be paid beyond one year. 
  
NOTE 8 – CONTINGENCIES 
 
As of December 31, 2024, 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, 2024, there were 492,843 shares available for future grant under the Data I/O Corporation 2023 Omnibus 
Incentive Compensation Incentive Plan (the “2023 Plan”).  At December 31, 2024, there were shares of Common Stock reserved 
for issuance for outstanding awards, consisting of 61,250 inducement reserve shares, 79,875 shares under the 2000 Plan, and 
530,775 shares under the 2023 Plan.  The inducement reserve shares remaining that were granted in 2023 consisted of 56,250 
RSU and 5,000 PSU, (which were not from the 2023 Plan, but were made under the terms of the 2023 Plan).  Pursuant to the 2000 
and 2023 Plans, 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 now granted under the 2023 Plan (previously the 2000 Plan) which for RSU 
awards generally vest over three or four years and one year for non-employee Directors.  Performance Share Unit (PSU) awards 
vesting based upon the three-year performance achievement on December 31, 2025 and 2026.  The performance measures for 
the PSUs awarded are revenue growth targets for 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.  Achieving a threshold measure earns 50% of the PSU target award; achieving the target 
measure earns 100% of the PSU target award; and achieving the maximum target measure earns 150% of the PSU target award.   
 
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 2024 and 2023, a total of 5,019 and 3,341 
shares, respectively, were purchased under the plan at average prices of $2.85 and $4.16 per share, respectively.  At December 
31, 2024 and 2023, 16,955 and 21,525 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 Data I/O 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, 2024 and 2023, there 
were 200,000 and 12,500 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 2024, 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, and as a result this 
requires a minimum six percent contribution to receive a four percent matching contribution. Our matching contribution expense 
for the savings plan, net of forfeitures, was approximately $217,000 and $253,000 in 2024 and 2023, respectively.  Employer 
matching contributions owed to the plan were $230,000 and $248,000 at December 31, 2024 and 2023, 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, 
2024 and 2023 was as follows:

During the years ended December 31, 2024 and 2023, 86,007 and 83,753 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%

primarily a result of the withholding tax of $337,000 on the repatriation of cash from China subsidiary in 2024.  Income tax

The valuation allowance for deferred tax assets increased $584,000 and decreased $639,000 during the years ended December 
31, 2024 and 2023, respectively.  The net deferred tax assets have a full valuation allowance provided due to uncertainty regarding 
our ability to utilize such assets in future years.  This full valuation allowance evaluation is based upon our volatile history of losses 
and the cyclical nature of our industry and capital spending.  Credit carryforwards consist primarily of research and experimental 
and foreign tax credits.  We intend to continue to reinvest foreign earnings of our operating subsidiaries. 
 
U.S. net operating loss carryforwards are $14.2 million on December 31, 2024 with expiration years from 2024 to 2035.  Utilization 
of net operating loss and credit carryforwards is subject to certain limitations under Section 382 of the Internal Revenue Code of 
1986, as amended. We have not had a Section 382 ownership change, but if we did the usage of these tax assets would have an 
income usage limitation based on the value of the Company at the time of the change times the federal long-term tax-exempt 
rate.

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 2021, 2022, 2023 and 2024 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.

NOTE 15 – SUBSEQUENT EVENTS 
 
In preparing the financial statements, the Company has reviewed all known events which occurred after December 31, 2024 
through the date on which the financial statements are available for issuance, for potential recognition or disclosure in the 
consolidated financial statements and footnotes.   
 
There were no other subsequent events which would require additional disclosures to the financial statements other than those 
already disclosed throughout the Notes to Consolidated Financial Statements. 
 
Item 9.  Changes in and Disagreements with Accountants on Accounting and Financial Disclosure 
None. 
 
Item 9A.  Controls and Procedures 
 
(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 (the “Evaluation Date”).  
Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of the Evaluation Date, our 
disclosure controls and procedures were not effective due to a material weakness in our internal control over financial reporting 
as described below.   
 
(b) Management’s Report on Internal Control Over Financial Reporting. 
 
Our management is responsible for establishing and maintaining adequate internal control over financial reporting.  Our internal 
control systems are designed to provide reasonable assurance to the Company’s management and board of directors regarding 
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: 
 
(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;  
(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 
(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.  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.  
 
Our management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2024.  
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, as of December 31, 2024, our internal control over financial reporting was not 
effective as of December 31, 2024 because of an identified material weakness in our internal control over financial reporting as 
described below:

10-K 
Material Weakness Identified by Management 
 
Management determined the following material weakness in internal control over financial reporting as of December 31, 2024. 
 
• In the areas of user access and segregation of duties related to the information technology system that support the 
Company’s financial reporting processes. 
 
As set forth below, management has taken and will continue to take steps to remediate the material weakness identified as of 
December 31, 2024.  Notwithstanding this material weakness, we have performed additional analyses and procedures to enable 
management to conclude that our consolidated financial statements included in this 2024 Form 10-K fairly present in all material 
respects our financial condition and results of operations as of and for the year ended December 31, 2024. 
 
Management’s Remediation Plan 
 
In response to the material weakness discussed above, we plan to continue and expand efforts already underway to remediate 
internal control over financial reporting, which include the following: 
 
• We are enhancing our processes around reviewing and provisioning access to key financial systems and ensuring 
appropriate segregation of duties; 
 
• We continue to enhance governance and reporting over the execution of these remediation action items, including 
expansion of mitigating controls where appropriate. 
 
Management and our Audit Committee will monitor these specific remedial measures and the effectiveness of our overall control 
environment.  A material weakness will not be considered remediated; however, until the applicable controls operate for a 
sufficient period of time and Management has concluded, through testing, that these controls are operating effectively.  
 
This annual report does not include an attestation report of the company’s registered public accounting firm regarding internal 
control over financial reporting.  Management’s report was not subject to attestation by the company’s registered public 
accounting firm pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act, which permanently exempts smaller 
reporting companies from complying with Section 404(b) of the Sarbanes-Oxley Act of 2002.   
 
(c) Changes in internal controls. 
 
There were no changes made in our internal controls during the period covered by this report that has materially affected or is 
reasonably likely to materially affect our internal control over financial reporting. 
 
Item 9B.  Other Information

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. 
 
Corporate Policy Relating to Trading in the Company's Stock 
 
 
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.  
 
Prohibited Activities 
 
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 

58 
10-K 
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.

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. 
 
 
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. 
 
 
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.   
 
 
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 
 
 
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. 
 
 
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. 
 

60 
10-K 
 
 
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: 
 
 
 
 
(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; 
 
 
 
 
(ii)  Company securities held by the Insider’s immediate family members who share the same household 
as the Insider; 
 
 
 
 
(iii)  Company securities held by a trust in which the Insider has an interest; and 
 
 
 
 
(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. 
 
 
 
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. 
 
 
 
 
(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. 
 
 
 
 
(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. 
 
 
 
 
(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. 
 
 
 
 
(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. 

61 
10-K 
 
 
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. 
 
 
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).   
 
 
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.   
 
 
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. 
 
 
 
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: 
 
 
 
 
(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; 

62 
10-K 
 
 
 
(ii)  The SEC may impose monetary penalties for missing Section 16 reporting deadlines;  
 
 
 
 
(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 
 
 
 
 
(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.

APPENDIX B 
 
FILING REQUIREMENTS FOR MORE THAN FIVE-PERCENT SHAREHOLDERS 
 
 
1. 
What special requirements apply to more-than-five-percent Shareholders?  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. 
 
 
2. 
What information is included in Schedule 13D and Schedule 13G?  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. 
 
 
3. 
When must a Schedule 13D or Schedule 13G be filed?  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.

ANNUAL MEETING OF SHAREHOLDERS 
May 15, 2025 
 
INFORMATION REGARDING PROXY 
 
This Proxy Statement and the accompanying form of proxy are furnished in connection with the solicitation of proxies by the Board of 
Directors (“Board of Directors”) of Data I/O Corporation (the “Company” or “Data I/O”) for use at the Annual Meeting of Shareholders 
to be held on Thursday, May 15, 2025, at 10:00 a.m. Pacific Daylight Time at Data I/O’s principal office, 6645 185th Ave NE, Suite 100, 
Redmond, Washington 98052, and at any adjournment of the meeting (the “Annual Meeting”).  Shareholders of record at the close of 
business on March 18, 2025 (the “Record Date”) are entitled to notice of, and to vote at, the Annual Meeting.  This Proxy Statement 
and a copy of Data I/O’s 2024 Annual Report to Shareholders are being mailed to shareholders on or about April 4, 2025. 
 
A proxy card is enclosed for your use.  You are requested on behalf of the Board of Directors to sign, date, and return the proxy card in 
the accompanying envelope, which is postage-paid if mailed in the United States or Canada. Alternatively, you may vote as provided 
in the instructions on the proxy card (for Computershare accounts: by the internet at http://www.envisionreports.com/DAIO or by 
telephone at 1-800-652-8683, and for other accounts: by internet at www.ProxyVote.com or by phone at 1-800-579-1639).  If you 
vote by the internet or by telephone, you do not need to mail back the proxy card. 
 
A proxy in the accompanying form, which is properly signed, dated and returned and not revoked, will be voted in accordance with its 
instructions.  To vote on the election of directors, check the appropriate box under Proposal 1 on your proxy card.  You may (a) vote 
“FOR” all of the director nominees as a group, (b) “WITHHOLD” authority to vote for all director nominees as a group, or (c) vote “FOR” 
all director nominees as a group except those nominees indicated to the contrary.  To vote on Proposal 2 to ratify the continued 
appointment of Grant Thornton LLP as Data I/O’s independent auditors for the calendar year ended December 31, 2025, check the 
appropriate box under Proposal 2 on your proxy card.  You may (a) vote “FOR” approval of the ratification of Grant Thornton LLP as 
Data I/O’s independent auditors, (b) vote “AGAINST” approval of the ratification of Grant Thornton LLP as Data I/O’s independent 
auditors, or (c) “ABSTAIN” from voting on the ratification of Grant Thornton LLP as Data I/O’s independent auditors.   To vote on 
Proposal 3, Say on Pay – Advisory Vote on Executive Compensation, you may vote (a) “FOR” the advisory resolution, (b) “AGAINST” 
the advisory resolution, or (c) “ABSTAIN” from voting on the advisory resolution on executive compensation.   
 
Proxies which are returned to Data I/O without instructions will be voted as recommended by the Board of Directors.  Any shareholder 
who returns a proxy may revoke it at any time prior to voting on any matter (without, however, affecting any vote taken prior to such 
revocation) by (i) delivering written notice of revocation to the Secretary of Data I/O at Data I/O’s principal office, (ii) executing and 
delivering to Data I/O another proxy dated as of a later date, or (iii) voting in person at the Annual Meeting. 
 
VOTING SECURITIES AND PRINCIPAL HOLDERS 
The only outstanding voting securities of Data I/O are shares of common stock (the “Common Stock”).  As of the Record Date, there 
were 9,239,731 shares of Common Stock issued and outstanding, and each such share is entitled to one vote at the Annual Meeting.  
The presence in person or by proxy of holders of record of a majority of the outstanding shares of Common Stock is required for a 
quorum for transacting business at the Annual Meeting.  Shares of Common Stock underlying abstentions will be considered present 
at the Annual Meeting for the purpose of calculating a quorum.  Under Washington law and Data I/O’s charter documents, if a quorum 
is present, the five nominees for election to the Board of Directors who receive the greatest number of affirmative votes cast at the 
Annual Meeting will be elected directors.  Abstentions and broker non-votes will have no effect on the election of directors because 
they are not cast in favor of any particular candidate. 
The proposal to ratify the continued appointment of Grant Thornton LLP as Data I/O’s independent auditors will be approved, if a 
quorum is present, if the number of votes cast in favor of the proposal exceeds the number of votes cast against the proposal.

Proxy 
Abstentions and broker non-votes on the proposals will have no effect because approval of the proposal is based solely on the votes 
cast.   
Say on Pay – The advisory vote on the compensation of Data I/O’s named executive officers will be approved, if a quorum is present, 
if the number of votes cast in favor of the advisory resolution exceeds the number of votes cast against the advisory resolution.  
Abstentions and broker non-votes on the advisory resolution will have no effect because approval of the advisory resolution is based 
solely on the votes cast. 
 
Proxies and ballots will be received and tabulated by Computershare, an independent business entity not affiliated with Data I/O. 
 
Effect of Not Casting Your Vote 
 
If you hold your shares in street name, it is critical that you instruct your broker or bank how to vote if you want it to count in Proposal 
1, the election of directors, and Proposal 3, Say on Pay .  Regulations no longer allow your bank or broker to vote your uninstructed 
shares in the election of directors on a discretionary basis.  If you hold your shares in street name and you do not instruct your bank 
or broker how to vote on Proposal 1, the election of directors, and Proposal 3, Say on Pay, votes will not be cast on your behalf for 
these Proposals.  Your bank or broker will, however, continue to have discretion to vote any uninstructed shares on Proposal 2, 
ratification of the appointment of Data I/O’s independent auditors.  If you are a shareholder of record and you do not cast your vote, 
votes will not be cast on your behalf on any of the items of business at the Annual Meeting.     
 
The Common Stock is traded on The NASDAQ Capital Market under the symbol “DAIO”.  The last sale price for the Common Stock, as 
reported by The NASDAQ Capital Market on March 18, 2025, was $2.45 per share.

CORPORATE GOVERNANCE 
 
Board Charters 
 
The Board of Directors has adopted Corporate Governance and Nominating Committee, Audit Committee and Compensation 
Committee Charters.  All our Charters are reviewed and updated periodically by our Board of Directors.  All of our Charters were 
reviewed during 2024 and again in early 2025 and no changes were made. The current versions of our Charters are posted on the 
corporate governance page of our website at https://www.dataio.com/Company/Investor-Relations/Corporate-Governance.aspx.  All 
of these Charters are consistent with the applicable requirements of United States security laws and our NASDAQ listing standards.   
 
Code of Ethics 
 
Our Code of Ethics was reviewed by our Board of Directors during 2024 and again in early 2025 and no substantive changes were 
made.  The current version of our Code of Ethics is posted on the Corporate Governance page of our website at 
https://www.dataio.com/Company/Investor-Relations/Corporate-Governance.aspx.  Data I/O’s Code of Ethics apply to all directors, 
officers and employees of Data I/O, including the named executive officers.  The key principles of the Code are to act legally, and with 
integrity in all work for Data I/O.  We will post any amendments to our Code of Ethics on the corporate governance page of our website 
at www.dataio.com/company/investorrelations/corporategovernance.aspx.  In the unlikely event that the Board of Directors 
approves any waiver to the Code of Ethics for our executive officers or directors, information concerning such waiver will also be 
posted on our website.  In addition to posting information regarding amendments and waivers on our website, the same information 
will be included in a Current Report on Form 8-K within four business days following the date of the amendment or waiver, unless 
website posting of such amendments or waivers is permitted by the rules of The NASDAQ Stock Market LLC. 
 
Clawback of Executive Compensation 
 
On October 25, 2023, the Board adopted an Incentive Compensation Recovery Policy (“Clawback Policy"), which is further discussed 
in the EXECUTIVE COMPENSATION section under Clawback of Executive Compensation in this document.   
 
Risk Oversight 
 
Our current Board of Directors consists of four independent directors, and one non-independent director, our Chief Executive Officer.  
Risk oversight is generally handled by our entire Board of Directors, although certain risk oversight areas such as internal control and 
cyber risk are handled by our Audit Committee, and compensation is handled by our Compensation Committee.  The Board leadership 
structure promotes effective oversight of the Company's risk management for the same reasons that the structure is most effective 
for the Company in general, that is, by providing the Chief Executive Officer and other members of senior management with the 
responsibility to assess and manage the Company's day-to-day risk exposure and providing the Board, and specifically the Audit 
Committee of the Board, with the responsibility to oversee these efforts of senior management. 
 
Director Independence 
 
Messrs. Brown, Smith and Larson, and Ms. Washlow are independent directors as defined by applicable U.S. Securities and Exchange 
Commission (“SEC”) rules and NASDAQ listing standards.  Mr. Wentworth was also an independent director, but was no longer 
independent as of September 1, 2024 when he became President. Mr. Ambrose, was no longer our Chief Executive Officer as of 
October 1, and was not an independent director. 
 
Leadership Structure 
 
Our Board Chair, Ms. Washlow, is an independent director, and Mr. Wentworth is our Chief Executive Officer, President, and Director.

PROPOSAL 1: ELECTION OF DIRECTORS 
 
At the 2024 Annual Meeting, the shareholders elected five directors to serve until the next Annual Meeting or until such director’s 
successor has been qualified and elected or such director’s earlier death, resignation or removal.  For the 2025 Annual Meeting, the 
Board of Directors has approved the five nominees named below.  All five nominees are currently members of the Board of Directors.  
Each of the nominees has indicated that they are willing and able to serve as directors.  However, should one or more of the nominees 
not accept the nomination, or otherwise be unwilling or unable to serve, it is intended that the proxies will be voted for the election 
of a substitute nominee or nominees designated by the Board of Directors.   
 
RECOMMENDATION:  The Board of Directors recommends a vote FOR each of the director nominees.  
 
William Wentworth, age 59, was elected a director of Data I/O effective May 18, 2023 and became President on September 1, 2024 
and Chief Executive Officer (CEO) on October 1, 2024.  Prior to that, he was the Principal Managing Partner of Wentworth Advisors, 
LLC a consulting firm.  He was a co-founder of Source Electronics Corporation in 1988, and he led a majority exit with HIG Capital in

THE BOARD OF DIRECTORS 
 
Communications with the Board of Directors 
 
Shareholders may communicate with the Board of Directors by sending an email to investorrelations@dataio.com or by sending a 
letter to Data I/O Corporation Board of Directors, c/o the Secretary, 6645 185th Ave NE, Suite 100, Redmond, WA 98052.  The Secretary 
will receive the correspondence and forward it to the Chair of the applicable Board of Directors Committee or to any individual director 
or directors to whom the communication is directed. 
 
BOARD COMMITTEES 
 
During the year ended December 31, 2024, there were 22 meetings of the Board of Directors.  Each of the incumbent directors who 
was on the Board of Directors during 2024 attended over 89% of the aggregate of the total number of meetings of the Board of 
Directors during their term of service on the Board of Directors.  Data I/O does not have a policy requiring members of the Board of 
Directors to attend the Annual Meeting, although we typically encourage our Board of Directors to attend. Ms. Washlow, Mr. Smith, 
and Mr. Wentworth attended our 2024 Annual Meeting telephonically and Mr. Ambrose and Mr. Brown attended in person.   
 
The Board of Directors had three standing Committees during 2024: The Audit Committee, the Compensation Committee and the 
Corporate Governance and Nominating Committee.  Each committee was comprised solely of independent directors during 2024, as 
defined by applicable SEC rules, NASDAQ listing standards including director independence generally as well as additional 
independence requirements for audit and compensation committees, and the Sarbanes-Oxley Act of 2002.  The following table shows 
the composition of the Board Committees and Board Leadership structure during 2024 and through the date of this Proxy Statement.

Audit Committee 
 
The Audit Committee appoints, oversees, evaluates, and engages independent certified public accountants for the ensuing year and 
approves the compensation and other terms of such engagement; reviews the scope of the audit; periodically reviews Data I/O’s 
program of internal control and audit functions; receives and reviews the reports of the independent accountants; and reviews the 
annual financial report to the directors and shareholders of Data I/O.  Each member of the Audit Committee is an independent director, 
as defined by applicable NASDAQ listing standards and the Sarbanes-Oxley Act of 2002.  During 2024 and through the date of this 
Proxy statement, at least 2 Audit Committee members are “audit committee financial experts” as defined by the applicable SEC rules 
adopted pursuant to the Sarbanes-Oxley Act of 2002.  The Audit Committee met four times during 2024 and recorded 100% committee 
attendance at such meetings held during their term of service.  See the “Report of the Audit Committee” for additional information. 
 
Corporate Governance and Nominating Committee 
 
The Corporate Governance and Nominating Committee, or “CGNC”, develops, recommends to the Board of Directors, and monitors a 
set of corporate governance principles applicable to Data I/O.  The CGNC seeks qualified candidates to serve on the Board of Directors, 
recommends them for the Board of Directors’ consideration for election as directors at the Annual Meeting of Shareholders and 
proposes candidates to fill vacancies on the Board of Directors.  The CGNC met seven times in 2024 and recorded no less than 100% 
committee attendance at such meetings held during their term of service.  The CGNC continues to seek qualified candidates and 
recommends the director nominees to the Board of Directors.  The CGNC identifies, evaluates, and recommends director nominees 
and Committee assignments which are described in greater detail below.  
 
As part of the process of selecting a new Chief Executive Officer and the transition necessary due to the planned retirement of Anthony 
Ambrose, the Board formed a Special Committee consisting of Ms. Washlow, Mr. Brown and Mr. Smith (all the independent directors 
excluding Mr. Wentworth, who was under consideration for the position.) The Committee recommended Mr. Wentworth for the CEO 
position and proposed transition arrangements with Anthony Ambrose. The Committee met three times and recorded 100% 
attendance. 
 
Compensation Committee 
 
The Compensation Committee is composed entirely of independent directors, as defined by applicable NASDAQ listing standards for 
compensation committees.  The Compensation Committee is responsible for setting and administering the policies which govern all 
of the compensation programs of Data I/O.  The Compensation Committee may delegate its authority and duties to subcommittees 
or individual members of the Compensation Committee as it considers appropriate.  

9 
 
Proxy 
 
The Compensation Committee makes recommendations to the Board of Directors concerning the compensation of Data I/O’s 
executive officers.  The Compensation Committee administers Data I/O’s long-term equity incentive plans.  The Compensation 
Committee reviews all employee benefit programs and approves significant changes in major programs and all new programs.  The 
Compensation Committee met four times during 2024 and recorded 100% committee attendance at such meetings held during their 
term of service. 
 
As authorized by the Compensation Committee charter, the Compensation Committee may retain consultants or other advisors, as 
well as purchase compensation surveys, to assist in carrying out its responsibilities.   
 
Consideration of Director Nominees 
 
The Corporate Governance and Nominating Committee has developed, and the Board has approved, Board Responsibilities and 
Director Recruitment Objectives, which further outline our directors’ roles and responsibilities and desired traits, diversity, 
characteristics, experience and criteria for selection.  The Corporate Governance and Nominating Committee in evaluating and 
determining whether to recommend a person as a candidate for election as a director consider, in light of the Board Responsibilities 
and Director Recruitment Objectives, considers the relevant management and/or technology industry experience of potential director 
candidates (such as experience as chief executive, operations or financial officer, or similar positions); business development, mergers 
and acquisitions experience; public/corporate board experience, diversity, knowledge of Data I/O; educational experience; 
commitment to maximizing shareholder value; certain values such as integrity, accountability, judgment and adherence to high 
performance standards; independence pursuant to applicable guidelines; ability and willingness to undertake the required time 
commitment to Board functions; shareholder input; and an absence of conflicts of interest with Data I/O.   
 
Director Diversity 
 
The Corporate Governance and Nominating Committee also considers issues of diversity, such as diversity of gender, race and national 
origin, education, professional experience and differences in viewpoints and skills.  The CGNC does not have a formal policy on Board 
diversity; however, the CGNC believes that it is important for Board members to represent diverse viewpoints and comply with specific 
applicable laws.  The composition and quantity of board members may be potentially impacted as we maintain compliance with these 
and future requirements.  In considering candidates for the Board, the CGNC considers the entirety of each candidate’s credentials in 
the context of these standards.  With respect to evaluating the nomination of continuing directors for re-election, the CGNC considered 
each director’s contributions to the company as well as the results of the Board of Directors self-evaluations process.  The following 
table presents a Board Diversity Matrix per prior NASDAQ requirements.

Identifying Director Nominees; Consideration of Nominees of the Shareholders 
 
The Corporate Governance and Nominating Committee may employ a variety of methods for identifying and evaluating nominees for 
directors.  The CGNC regularly assesses the size of the Board, the need for particular expertise on the Board, and whether any vacancies 
on the Board are expected due to retirement or otherwise.  In the event that vacancies are anticipated, or otherwise arise, the CGNC 
considers various potential candidates for director which may come to the CGNC’s attention through current Board members, 
professional search firms, shareholders, or other persons and evaluates these candidates in light of the Board Responsibilities and 
Director Recruitment Objectives.  These candidates are evaluated at regular or special meetings of the CGNC and may be considered 
at any point during the year. 
 
The Corporate Governance and Nominating Committee will consider candidates recommended by shareholders, when the 
nominations are properly submitted, under the criteria summarized above in “Consideration of Director Nominees” and in accordance 
with the procedures described below in “Shareholder Nominations and Proposals for the 2025 Annual Meeting of Shareholders.”  
Following verification of the shareholder status of persons proposing candidates, the CGNC makes an initial analysis of the 
qualifications of any candidate recommended by shareholders or others pursuant to the criteria summarized above to determine if 
the candidate is qualified for service on the Data I/O Board of Directors before deciding to undertake a complete evaluation of the 
candidate.  If any materials are provided by a shareholder or professional search firm in connection with the nomination of a director 
candidate, such materials are forwarded to the CGNC as part of its review.  Other than the verification of compliance with procedures 
and shareholder status, and the initial analysis performed by the CGNC, a potential candidate nominated by a shareholder is treated 
like any other potential candidate during the review process by the CGNC.  For eligible shareholder nominees to be placed on the 
ballot for the 2025 Annual Meeting of Shareholders, shareholders were required to deliver nominations for proposed director 
nominees to Data I/O by February 14, 2025.  No formal candidate nominations were made by shareholders for election at the 2025 
Annual Meeting. Existing Directors were identified as follows: Mr. Wentworth was initially identified by a Board member; Mr. Smith 
and Mr. Larson were initially identified by discussions with significant shareholders and the Board; Ms. Washlow was initially identified 
and introduced by a former Board member; and Mr. Brown was initially identified and introduced by a former member of 
management.

Certain Relationships and Related Transactions 
 
Our Audit Committee is charged with monitoring and reviewing issues involving potential conflicts of interest, and reviewing and 
approving related party transactions as set forth in the Code of Ethics, which is posted on the corporate governance page of our 
website at https://www.dataio.com/Company/Investor-Relations/Corporate-Governance.aspx.  Under our Code of Ethics, our 
directors, officers and employees are expected to avoid conflicts of interest with Data I/O and are required to report any such conflicts 
of interest to our Chief Executive Officer or Chief Financial Officer, or to the Chair of our Audit Committee.  Our Audit Committee 
reviews all such transactions and relationships by our directors and executive officers that come to its attention either through the 
director and officer questionnaires or otherwise, and considers whether to approve or take other appropriate action with respect to 
such transactions or relationships.  During 2023 and 2024, no related party transactions that were significant or material occurred.  
 
BOARD COMPENSATION 
 
Employee directors (Anthony Ambrose and William Wentworth (after 9/1/2024)) do not receive additional compensation for serving 
on the Board of Directors.  Because Mr. Wentworth, was appointed President on September 1, 2024, he received pro-rated 
compensation for serving on the Board of Directors during 2024. During 2024, non-employee directors received a cash retainer of 
$7,750 for each quarter of service.  Data I/O paid additional quarterly compensation to the non-employee directors who served as 
Chair of the Board of Directors or as a Committee chair: $3,750 for Chair of the Board of Directors; $2,500 for Chair of the Audit 
Committee; $2,000 for Chair of the Compensation Committee; and $2,000 for Chair of the Corporate Governance and Nominating 
Committee.  Fees are prorated based on time served for changes in directors and assignments. 
 
In addition, each non-employee Board of Directors member as of May 16, 2024, was granted a restricted stock award for 14,100 shares 
of Data I/O stock.  The restricted stock awards were granted under the provisions and terms of the 2023 Omnibus Incentive 
Compensation Plan (“2023 Plan”) and generally vest in one year or on the date of the next Annual Meeting, if earlier.  Data I/O also 
reimburses non-employee directors for actual travel and out-of-pocket expenses incurred in connection with service to Data I/O. 
 
Each Data I/O non-employee member of the Board of Directors is required to achieve ownership of Data I/O stock at least equal to 
three times the annual director cash retainer fee based on Data I/O’s then current share price.  Non-employee directors have five 
years from their initial election or appointment to meet the ownership target requirement.  Amounts that count toward meeting the 
target requirement include: shares owned; shared ownership (shares owned or held in trust by immediate family); and the gain 
amount from any in-the-money vested options.  If the stock ownership target requirement has not been met by any non-employee 
director, until such time as such director reaches the target requirement, he or she will be required to retain any Data I/O shares 
issued by Data I/O to such director (other than those disposed of to pay for the exercise and associated taxes on those shares).  As of 
the Record Date, Mr. Brown has met the stock ownership target requirement and Ms. Washlow, Mr. Smith and Mr. Larson, as a result 
of their recent appointments, have not yet met the requirement.  
 
The Chief Executive Officer (“CEO”) is required to achieve ownership of Data I/O stock of at least two times the base pay of the CEO 
based on Data I/O’s then current share price.  The CEO has five years from appointment to meet the ownership target requirement.  
Amounts that count toward meeting the target requirement are the same as for the Board of Directors.  If the stock ownership target 
requirement has not been met by the CEO, until such time as the CEO reaches the requirement amount, he or she will be required to 
retain any Data I/O shares issued by Data I/O (other than those disposed of to pay for the exercise and associated taxes on those 
shares).  Because the CEO, Mr. Wentworth, was recently appointed, as of the Record Date the CEO did not meet the stock ownership 
target requirement, but he has 5 years to meet the target stock ownership requirement. 
 
We have adopted a “Securities Trading Policy” that (i) governs the purchase, sale, and/or other dispositions of the Company’s securities 
by our directors, officers, employees, and consultants that we believe is reasonably designed to promote compliance with insider 
trading laws, rules and regulations, and the exchange listing standards applicable to us; and (ii) includes a prohibition against hedging 
transactions.  This Policy is included in the 2024 Annual Report on Form 10-K under Exhibit 19.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE 
 
Section 16(a) of the Securities Exchange Act of 1934 requires Data I/O’s directors, certain officers and persons who own more than 
ten percent (10%) of Data I/O’s Common Stock (“Reporting Persons”) to file with the SEC initial reports of ownership and reports of 
changes in ownership of Common Stock and other equity securities of Data I/O.  Reporting Persons are required by SEC regulations to 
furnish Data I/O with copies of all Section 16(a) reports.  
 
Delinquent Section 16(a) Reports 
 
Based on the information provided to Data I/O, a Director’s Form 4 (Douglas Brown) reporting a small open market purchase of shares 
was filed one day late because of a communication delay.  An Officer’s Form 4 (Gearld Ng) reporting a Restricted Stock Unit vesting 
with the withholding of shares to cover taxes, was filed approximately 8 months late, due to an oversight that inadvertently resulted 
in a missed filing. The oversight was discovered after doing a year-end reconciliation of holdings and the late filing was made. 
 
REPORT OF THE AUDIT COMMITTEE 
 
The Audit Committee oversees Data I/O’s financial reporting process on behalf of the Board of Directors.  Management has the primary 
responsibility for the consolidated financial statements and the reporting process, including the systems of internal controls.  Audit 
Committee members are not professional accountants or auditors, and their functions are not intended to duplicate or to certify the 
activities of management or the independent auditors.  In fulfilling its oversight responsibilities, the Committee reviewed the audited 
consolidated financial statements in the Annual Report (Form 10-K) with management, including a discussion of the quality, not just 
the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the 
financial statements. 
 

13 
 
Proxy 
The Committee reviewed with the independent auditors, who are responsible for expressing an opinion on the conformity of those 
audited consolidated financial statements with generally accepted accounting principles in the United States, their judgments as to 
the quality, not just the acceptability, of Data I/O’s accounting principles and such other matters as are required to be discussed by 
the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the Commission, with the Committee 
under generally accepted auditing standards.  In addition, the Committee has discussed with the independent auditors the auditors’ 
independence from management and Data I/O, including the matters in the written disclosures and the letter provided by the 
independent auditors, as required by the applicable requirements of the Public Company Accounting Oversight Board and the SEC for 
independent auditor communications with Audit Committees concerning independence, and considered the compatibility of non-
audit services with the auditors’ independence.   
 
The Committee selects and engages Data I/O’s independent auditors, is involved in selecting and approving the independent auditors’ 
lead audit partner, and discusses the overall scope and plans for the audits.  The Committee meets with the independent auditors, 
with and without management present, to discuss the results of their examinations, their evaluations of Data I/O’s internal controls, 
and the overall quality of Data I/O’s financial reporting.  The Committee held four meetings during 2024, of which three were attended 
by Data I/O’s independent auditors. 
 
In reliance on the reviews and discussions referred to above, the Committee recommended to the Board of Directors (and the Board 
has approved) that the audited consolidated financial statements be included in Data I/O’s Annual Report (Form 10-K) for the year 
ended December 31, 2024, for filing with the Securities and Exchange Commission.  The Committee has considered the Shareholder 
vote of approval of 90.9% on May 16, 2024, as well as the impact of changing independent auditors and has selected Grant 
Thornton LLP as Data I/O’s auditors for the current year.

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

Proxy 
During the year, circumstances may arise when it may become necessary to engage the independent auditors for additional services 
not contemplated in the original pre-approval.  In those circumstances, the Audit Committee has delegated pre-approval authority to 
the Chair of the Audit Committee for those instances when pre-approval is needed prior to a scheduled Audit Committee meeting.  
These additional approvals should be reported at the next scheduled Audit Committee meeting.   
 
For 2024, all services provided by the independent auditors were pre-approved.   
 
EXECUTIVE COMPENSATION 
 
Key organizational leadership transition occurred in the fourth quarter of 2024 with the retirement and transition of Anthony Ambrose 
and the appointment of a new CEO and President, William Wentworth.  Subsequent changes have also occurred in the leadership of 
the Sales, Marketing and Engineering functions and corresponding changes in the strategic and operational direction of these groups.   
 
Shareholder Vote  
 
At our 2024 Annual Meeting of Shareholders, our shareholders approved, in an advisory vote, the compensation of our Named 
Executive Officers, as disclosed in the Executive Compensation discussion and analysis, the compensation tables and the related 
disclosures in our Proxy Statement.  The proposal was approved by our shareholders with 85.5% of the votes cast voting “for” approval 
and 14.3% voting “against” approval.  In light of the level of approval by our stockholders, the Compensation Committee considered 
the result of the vote and did not make changes to our compensation policies or practices specifically in response to the stockholder 
vote. The frequency of Say on Pay advisory votes was selected to be every year by 86.9% of the vote of the shareholders. 
 
Elements of Our Company’s Compensation Plan  
 
Annual executive officer compensation consists of the following elements which are described in more detail below: 
• 
Annual base salary; 
• 
Management Incentive Compensation Plan or “MICP”; 
• 
Long-term equity incentives; 
• 
Benefits;  
• 
Perquisites and other perceived benefits; and 
• 
Individual Executive Officers’ Performance. 
  
It is the Compensation Committee’s policy to set total executive officer compensation at competitive levels based on compensation 
surveys with similar positions in similar sized company revenue ranges and at levels sufficient to attract and retain a strong, motivated 
leadership team.  Our philosophy for compensation of executive officers is based on the following two principles: 
 
i. 
Executive base compensation levels should be established by comparison of job responsibility to similar 
positions in comparable companies and be adequate to retain highly-qualified personnel; and 
ii. 
Variable compensation should be a critical element of compensation and be set to be comparably competitive and 
to provide strong incentives to improve performance and shareholder value. 
 
• 
Annual Base Salary.  The Compensation Committee establishes a base salary structure for each executive officer position.  
This structure defines the salary levels and the relationship of base salary to total cash compensation.  The Compensation 
Committee reviews the salary structure periodically. 
 
• 
MICP.  The MICP offers each executive officer a performance-based opportunity to earn the variable component of annual 
cash compensation in an amount tied to a percentage of the executive officer’s base salary.  The Compensation Committee’s 
philosophy in setting executive MICP percentages and the formulas for MICP payout is to pay above average total 
compensation for better than average historical or expected financial performance and below average compensation for 
lower than or average historical or expected financial performance.  The percentages of base salary targeted for MICP payout 
(“the MICP Target”) for specific executive officers for a given year are generally the same as the previous year but can be 
changed by the Compensation Committee on an annual basis. The MICP payout can range from 0% to 200% of each 
executive’s MICP Target based upon the achieved MICP Measures for the period.  The 2023 and 2024 MICP Target amounts 
for our executive officers based on a full year of their applicable base pay were as follows:  (Wentworth’s prorated target

amount for the period actually worked in 2024 was $69,400.  Ng’s prorated target amount for the period actually worked in

The Compensation Committee determined for 2023 and again for 2024 that it was critical to emphasize profitability.  For the 
profitability measure: Financial Performance (“FP”) which is based on achievement of various levels of operating income as a 
percentage of revenue. (See below for the Financial Performance Matrix.)   
 
For 2023, it was determined that profitability was the most critical focus and that 100% of the MICP measure would be FP. 
For 2024, it was determined again, profitability was the most critical focus, however the measurement target was modified 
to EBITDA (Earning Before Interest Taxes Depreciation Amortization) and translated the prior Operating Profit target 
percentages to EBITDA approximate equivalents. For 2025, Financial Performance continues to be the most critical focus to 
target incentive compensation on for our Named Executive Officers 
  
The Compensation Committee believes that for 2023, 2024 and 2025, the applicable measures of key results for Data I/O 
have affected or will affect near-term and long-term shareholder value.  A greater or lesser percentage of MICP Target is to 
be paid based on Data I/O’s actual achievement of these measures with the payout target typically based on company 
financial plans as the Board determines appropriate.  For 2023, the operating income measure resulted in a payout of 27% 
for the MICP. For 2024, as a result of the EBITDA loss, the FP measurement resulted in no MICP payout because results were 
below the threshold. The Compensation Committee retains discretion to adjust the calculation of the two measures for 
changes outside normal business operations such as acquisitions or asset sales.

Long-Term Equity Incentives.  The Compensation Committee approves grants under the Data I/O Corporation 2023 Omnibus 
Incentive Compensation Plan (the “2023 Plan”) formerly under the Data I/O Corporation 2000 Stock Compensation Incentive 
Plan (the “2000 Plan”).  The 2023 Plan is Data I/O’s only long-term employee equity incentive plan.  The primary purpose of 
the 2023 Plan is to make a significant element of executive pay a reward for taking actions which maximize shareholder value 
over time.  Generally, new option, restricted stock unit and/or performance stock unit awards are granted under the 2023 
Plan.  New options or stock awards may also be granted to the Board of Directors under the 2023 Plan.  When the 2023 Plan 
was approved, all shares remaining in the 2000 Plan were transferred to the 2023 Plan, and future awards will be made under 
the 2023 Plan.    
 
Starting in 2023, under the provisions of the 2023 Plan, a portion of the equity awards to executives were Performance Stock 
Units (“PSU”) (roughly 20% based on achieving the target level performance) and 80% Restricted Stock Units (“RSU”).  The 
performance measures for the 2023 PSUs awarded are revenue growth targets for the three-year period ending December 
31, 2025. Achieving a threshold growth measure earns 50% of the PSU target award; achieving the target growth measure 
earns 100% of the PSU target award; and achieving the maximum target growth measure earns 150% of the PSU target award. 
 
In 2024, equity awards for existing executives were 50% RSUs and 50% PSUs.  The performance measures for the executives’ 
PSUs were 50% based on revenue targets for the three-year period ending December 31, 2026, and 50% based on EBITDA 
targets for the three-year period December 31, 2026.  Each measure with a threshold, target and maximum target. 
 
Award Criteria 
The Compensation Committee grants options, RSU and/or PSU awards based primarily on its perception of the executive’s 
ability to affect future shareholder value and secondarily on the competitive conditions in the market for highly-qualified 
executives who typically command compensation packages which include a significant equity incentive.  All RSU and PSU 
awards granted to our executive officers in 2024 and 2023 were based on these criteria.   
 
Exercise Price 
Historically, all options granted by Data I/O have been granted with an exercise price equal to the fair market value (an 
average of the day’s high and low selling price) of Data I/O’s Common Stock on the date of grant and, accordingly, will only 
have value if Data I/O’s stock price increases.  Options granted to employees in 2024 are non-qualified.   
 
Vesting and Exercise 
Options granted to employees generally vest quarterly over four years at a rate of 6.25% per quarter and have a six-year 
term.  The current primary form of equity compensation has been restricted stock unit grants. For 2023, RSU grants to 
executives vest annually over a three- or four-year period.  All the 2023 PSU awards vest upon the three-year performance 
achievement on December 31, 2025.  For 2024, RSU grants to executives vest annually over a three-year period.  All the 2024 
PSU awards vest upon achievement of the two possible three-year performance measures on December 31, 2026. RSU grants 
to non-employee Directors vest in one year or on the date of the next Annual Meeting of Shareholders, if earlier.  All grants 
are subject to possible acceleration of vesting in connection with certain events leading to a change in control of Data I/O or 
in the event in a change in control or at any other time at the discretion of the Compensation Committee.  All options granted 
to executive officers are issued in tandem with limited stock appreciation rights (“SARs”), which become exercisable only in 
the event of a change in control of Data I/O.  See: “Change in Control and other Termination Arrangements.” 
 
Award Process 
The timing of our typical grant/award is usually determined well in advance, with approval at a scheduled meeting of our 
Board of Directors or its Compensation Committee with the grant date generally to be effective on the date of our next Annual 
Meeting of Shareholders or, for employees, the first day of the following month. (June 1st for annual refresh grants was 
selected as no typically planned public releases coincide with or around this date.)  The Annual Meeting of Shareholders does 
not coincide with any of our scheduled earning releases.  We do not anticipate option, RSU or PSU awards at other dates, 
except for grants/awards to new employees based on generally the first of the month following their first date of employment 
or in specific circumstances approved by the Compensation Committee.  The grant/award date is established when the 
Compensation Committee approves the grant/award and all key terms have been determined.  If at the time of any planned 
grant/award date, any member of our Board of Directors or Executive Officers is aware of material non-public information, 
the Company would not generally make the planned grant/award.  In such an event, as soon as practical after material 
information is made public, the Compensation Committee would authorize the delayed grant/award.

Proxy 
• 
Benefits.  Executive Officers of Data I/O are eligible for the same benefits as other Data I/O employees.  Data I/O has no 
defined benefit pension programs.  Data I/O has a 401(k) tax qualified retirement savings plan in which all U.S. based 
employees, including U.S. Executive Officers are able to contribute the lesser of up to 100% of their annual salary or the limit 
prescribed by the IRS on a Roth or pre-tax basis. Data I/O’s match formula is 100% on the first 2% and 50% on the next 4%, 
which requires a 6% contribution to receive a 4% matching contribution. Matching contributions in any year require 
employment on December 31, except in the case of retirement per the plan, and vest after three years of service credit.   
 
• 
Perquisites and Other Personal Benefits.  We believe perquisites are not conditioned upon performance, create divisions 
among employees, undermine morale, and are generally inconsistent with our compensation philosophy and policy of 
equitable treatment of all employees based upon their contribution to our business.  No executive officer received perquisites 
valued at $10,000 or more in 2024 or 2023. 
 
• 
Individual Executive Officers’ Performance.  The base salary of each executive officer is reviewed annually by the President 
and Chief Executive Officer.  This is done on the basis of a review by the President and Chief Executive Officer, evaluating the 
executive’s prior year performance against their individual job responsibilities and attainment of corporate objectives and 
Data I/O’s financial performance.  In developing executive compensation packages to recommend to the Compensation 
Committee, the President and Chief Executive Officer considers, in addition to each executive’s prior year performance, the 
executive’s long-term value to Data I/O, the executive’s pay relative to that for comparable surveyed jobs, the executive’s 
experience and ability relative to executives in similar positions, and the current year increases in executive compensation 
projected in industry surveys. 
 
The Compensation Committee then reviews the President and Chief Executive Officer’s recommendations for executive 
officers’ total compensation and approves final decisions on pay for each executive officer based on the President and Chief 
Executive Officer’s summary of the executive officer’s performance and on the other criteria and survey data described above.  
In this process, the Compensation Committee consults with Data I/O’s President and Chief Executive Officer. 
 
The base salary, total cash compensation, and long-term equity incentive compensation for the President and CEO are 
reviewed annually by the Compensation Committee.  This review includes a written evaluation of the CEO’s performance for 
the previous year.  The Compensation Committee meets annually without the President and Chief Executive Officer to 
evaluate his performance and to develop a recommendation for his compensation for the coming year.  In addition to 
reviewing Data I/O’s financial performance for the prior year, the Committee reviewed compensation surveys for chief 
executive officers and the President and Chief Executive Officer’s individual performance, including development and 
execution of short-term and long-term strategic objectives, Data I/O revenue growth and profitability, the achievement of 
which is expected to increase shareholder value.   
 
The Compensation Committee determined the compensation package, including salary, bonus, MICP participation, PSU 
awards, RSU awards, and other benefits for Mr. Wentworth (and previously for Mr. Ambrose), President and Chief Executive 
Officer, based on the Committee’s perception of his qualifications for the position and his ability to affect future shareholder 
value, results delivered, compensation surveys and the competitive conditions in the market.  
 
Consideration of Risk in Compensation 
 
The Compensation Committee believes that promoting the creation of long-term value discourages behavior that leads to excessive 
risk.  The Compensation Committee believes that the following features of our compensation programs provide incentives for the 
creation of long-term shareholder value and encourage high achievement by our executive officers without encouraging inappropriate 
or unnecessary risks: 
 
• 
Our long-term incentives in the form of stock options, RSU, and/or PSU awards are at the discretion of the Compensation 
Committee and not formulaic. 
 
• 
Stock options become exercisable over a four-year period and remain exercisable for up to six years from the date of grant, 
RSU awards vest over a three- or four-year period, and PSU awards vest based on achievement over a three-year performance 
period, encouraging executives to look to long-term appreciation in equity values. 
 

18 
 
Proxy 
• 
We balance short and long-term decision-making with the annual cash incentive program and equity in the form of stock 
options, RSU, and/or PSU that vest over three- or four-years. 
 
• 
The metrics used in the MICP measure are set by the Compensation Committee, which believes it will drive shareholder value.  
Moreover, the Committee attempts to set ranges for these measures that encourage success without encouraging excessive 
risk-taking to achieve short-term results. The PSU measures which are cumulative over time further balance longer-term with 
short-term outcomes. 
 
• 
In addition, the overall MICP incentive compensation cannot exceed two times the MICP Target amount, no matter how much 
performance exceeds the measures established for the year. 
 
Accounting and Tax Considerations of our Compensation Program  
 
Options granted to employees are non-qualified options, when awarded, because of the more favorable tax treatment for Data I/O.  
We are required to value granted stock options under the fair value method and expense those amounts in the income statement 
over the stock option’s remaining vesting period.  Restricted stock is valued at its fair value on the award date and is expensed over 
its vesting period. 
 
We have structured our compensation program in the past to comply with Internal Revenue Code Sections 162(m) and 409A.  Under 
Section 162(m) of the Internal Revenue Code, a limitation was placed on tax deductions of any publicly-held corporation for individual 
compensation to covered employees (generally the chief executive officer and the three other most highly compensated executive 
officers, other than the chief financial officer, whose compensation must be disclosed pursuant to rules and regulations under the 
Securities Exchange Act of 1934) exceeding $1 million in any taxable year. The Compensation Committee is aware of this limitation 
and believes that no compensation paid in 2023 or 2024, or expected to be paid in 2025, by Data I/O will exceed the $1 million 
limitation of Section 162(m) except possibly related to a change of control. The Section 162(m) treatment will continue to be part of 
future compensation considerations. 
 
Clawback of Executive Compensation 
  
The Board of Directors believes that it is in the best interests of the Company and its shareholders to create and maintain a culture 
that emphasizes integrity and accountability and that reinforces the Company's compensation philosophy. On October 25, 2023, the 
Board adopted an Incentive Compensation Recovery Policy (“Clawback Policy") which provides for the recovery of erroneously 
awarded incentive compensation in the event that the Company is required to prepare an accounting restatement due to material 
noncompliance of the Company with any financial reporting requirements under the federal securities laws. This Clawback Policy is 
designed to comply with Section 10D of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), related rules and the 
listing standards of the Nasdaq Stock Market or any other securities exchange on which the Company’s shares are listed in the future.  
 
Change in Control and other Termination Arrangements  
 
• 
Change in Control Arrangements.  Data I/O has entered into agreements with Mr. Ng (the “Executive Agreement”) and with 
Mr. Wentworth (the “Executive Employment Agreement”), which entitle them to receive payments if they are terminated 
without cause or resign with good reason within specified periods before or after the occurrence of certain events deemed 
to involve a change in control of Data I/O.  The Executive Agreement and the Executive Employment Agreement ensure 
appropriate incentives are in place for Messrs. Ng and Wentworth to complete any change in control related transaction and 
transition, as well as comply with the provisions of Section 409A of the Internal Revenue Code.  The Executive Agreement 
states that the resulting additional severance will be calculated under the Executive Agreement based on Data I/O’s standard 
severance arrangements in place immediately preceding the date of a change in control (See: “Other Termination 
Arrangements” below for current severance policy).  The Executive Agreement and Employment Agreement provide for 
continuation and vesting in Data I/O’s matching 401(k) contributions through the date of termination after a change in control 
and include a reimbursement allowance of $20,000 for outplacement services.  The Executive Agreement has a transaction 
closing incentive of one-half year’s annual salary for Mr. Ng to encourage the consideration of all forms of strategic 
alternatives. 
 

19 
 
Proxy 
Data I/O’s 2024 RSU and PSU awards have been granted pursuant to the provisions of the 2023 Plan. Prior year’s awards were 
under either the 2023 Plan or the 2000 Plan.  The Change in Control provision applicable to the 2000 Plan and the 2023 Plan 
are as follows: 
 
2000 Plan 
The 2000 Plan allows for the granting of “Awards”, which include options, restricted stock and other awards made pursuant 
to the 2000 Plan.  Subject to any different terms set forth in the award agreement, vesting of “qualifying” options and 
restricted stock awards may be affected by a Change in Control as described out in the table below.  A “Change in Control” is 
defined to include (i) a merger or consolidation of the Company in which more than 50% of the voting power of the Company’s 
outstanding stock after the transaction is owned by persons who are not shareholders immediately prior to such transaction, 
and (ii) the sale or transfer of all or substantially all of the Company’s assets.  A “Qualifying Award’ is defined as an option or 
other Award that has been held for at least 180 days as of the Change of Control.  “Qualifying Shares” means common stock 
issued pursuant to a Qualifying Award which are subject to the right of Data I/O to repurchase some or all of such shares at 
the original purchase price (if any) upon the holder’s termination of services to Data I/O.  
 
2023 Plan 
The 2023 Omnibus Incentive Compensation Plan (“2023 Plan”) replaced the 2000 Plan going forward for new awards, and 
was approved by the shareholders at the 2023 Annual Meeting. The 2023 Plan has substantially similar treatment of an award 
as the amended 2000 Plan in the event of a Change in Control. 
 
Treatment of Awards on a Change in Control 
Acceleration of Vesting 
The outstanding Awards do not remain outstanding or are 
not assumed by the surviving entity or replaced with 
comparable Awards. 
Subject to certain limitations, the vesting of Qualifying 
Awards is accelerated in full.  Restricted stock will vest and 
options will be exercisable in full prior to the effective date of 
the Change of Control.   
The outstanding Awards remain outstanding after a Change 
of Control or are assumed by the surviving entity or replaced 
with comparable Awards. 
Subject to certain limitations, the vesting of outstanding 
Qualifying Awards will be accelerated to the extent of 25% of 
the unvested portion thereof.  The remaining 75% of the 
unvested portion will vest in accordance with the vesting 
schedule set forth in the applicable Award agreement.   
The outstanding Awards remain outstanding after a Change 
of Control or are assumed by the surviving entity or replaced 
with comparable Awards, but the holder of a Qualifying 
Award is terminated involuntarily within one year of the 
Change of Control. 
All Awards held by such person will be accelerated in full.  
Restricted stock will vest and options will be exercisable in full 
for a period of 90 days commencing on the effective date of 
the involuntary termination, or if shorter, the remaining term 
of the option.   
 
In 1983, Data I/O adopted a SAR Plan which allows the Board of Directors to grant to each director, executive officer or holder 
of 10% or more of the stock of Data I/O a SAR with respect to certain options granted to these parties.  A SAR has been 
granted in tandem with each option granted to an executive officer of Data I/O.  SARs granted which have been held for at 
least six months are exercisable for a period of 20 days following the occurrence of either of the following events: (i) the close 
of business on the day that a tender or exchange offer by any person (with certain exceptions) is first published or sent or 
given if, upon consummation thereof, such person would be the beneficial owner of 30% or more of the shares of Common 
Stock then outstanding; or (ii) approval by the shareholders of Data I/O (or, if later, approval by the shareholders of a third 
party) of any merger, consolidation, reorganization or other transaction providing for the conversion or exchange of more 
than 50% of the outstanding shares of Data I/O’s Common Stock into securities of a third party, or cash, or property, or a 
combination of any of the foregoing. Currently, only one option grant remains outstanding that includes a SAR.  
 
• 
Other Termination Arrangements.  Data I/O has a severance policy for U.S. employees that provides for severance payouts 
for terminations without cause based upon years of service.  The current formula, effective March 1, 2014, is 1 week pay for 
each year of service with a limit of four months’ pay. Mr. Ng and Mr. Wentworth had at March 18, 2024, approximately 1.7 
and 1/2 years of service, respectively.  Mr. Wentworth is entitled to a one year of base salary severance, except in the case 
of a change in control, as part of his employment agreement.  Mr. Ng is entitled to a one-half year of base salary severance, 
except in the case of a change in control, as part of his employment arrangement.  Data I/O does not have a formal policy 
regarding executive severance but has generally provided an amount it believes is consistent with severance typically 
provided for executives in similar positions and with similar periods of service.

The following graph shows the Compensation Actually Paid (CAP) versus Total Shareholder Return (TSR).  The CAP reflects in 2022 and 
2024 the lower incentive compensation due to losses and in 2023 a lower net income level as well as lower equity values related to 
stock prices.  The declining TSR has a correlation with the declines in CAP. The PEO CAP was impacted by the turnover in PEOs in 2024.

PROPOSAL 2:  RATIFICATION OF INDEPENDENT AUDITORS 
 
The Board of Directors requests that the shareholders ratify the continued appointment of Grant Thornton LLP to serve as Data I/O’s 
independent auditors for calendar year 2025.  Grant Thornton LLP examined the consolidated financial statements of Data I/O for the 
year ended December 31, 2024.  Representatives of Grant Thornton LLP are invited to be present at the Annual Meeting to make a 
statement if they desire to do so and to respond to questions by shareholders. They confirmed that they expect to be present. 
 
The Board recommends a vote “FOR” the continued appointment of Grant Thornton LLP to serve as Data I/O’s independent auditors 
for calendar year 2025. 
 
 
 
PROPOSAL 3: SAY ON PAY - ADVISORY VOTE ON EXECUTIVE COMPENSATION 
 
In accordance with Section 951 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Section 14A of the Exchange 
Act, the Board of Directors requests that the shareholders approve, on an advisory basis, the compensation paid to Data I/O’s Named 
Executive Officers, as described in “Executive Compensation”, pursuant to the following Advisory Resolution:  
 
“RESOLVED, that Data I/O’s shareholders approve, on an advisory basis, the compensation of Data I/O’s named executive officers, as 
disclosed in Data I/O’s Proxy Statement for the 2025 Annual Meeting of Shareholders pursuant to the compensation disclosure rules 
of the Securities and Exchange Commission, including the 2024 Summary Compensation Table and the other related tables and 
disclosure.”  
Our executive compensation program contains elements of cash, incentive and equity-based compensation and is designed to align 
the interests of our executives with those of our shareholders.  The “Executive Compensation” section of this Proxy Statement 
describes in detail our executive compensation programs.   
The Board has implemented an executive compensation program that is intended to reward financial performance based on goals 
established by the Board.  The Board fosters a performance-oriented culture by linking a significant portion of each executive officer’s 
compensation to overall Company financial performance (as measured in 2024 by EBITDA targets and Revenue Growth targets) which 
the Company believes are the critical metrics for Data I/O and its shareholders.  We believe that equity awards (options, RSUs, and 
PSUs) align the interests of our executives with those of our long-term shareholders by encouraging long-term performance and 
incentivizing our executives to increase long-term shareholder value.  Equity awards represent a key component, and are a significant 
portion, of our executive compensation.   
The Board has designed Data I/O’s executive compensation program to attract, motivate, reward and retain our executive officers to 
achieve Data I/O’s corporate objectives and increase shareholder value.   
The Say on Pay vote is advisory and not binding on Data I/O or the Board of Directors; however, the Board will consider the outcome 
of the vote when making future compensation decisions for our executive officers. 
The Board recommends a vote “FOR” the Advisory Resolution (Say on Pay) approving the compensation of the Company’s named 
executive officers as described in this Proxy Statement.

Proxy 
SHAREHOLDER NOMINATIONS AND PROPOSALS FOR THE 2025 AND 2026 ANNUAL MEETING OF SHAREHOLDERS 
 
Data I/O’s Bylaws provide that advance notice of nominations for the election of directors at a meeting of shareholders must be 
delivered to or mailed and received by Data I/O at its principal offices on or before February 14, 2025, in the case of the 2025 Annual 
Meeting of Shareholders, and in the case of a special meeting of shareholders to elect directors, the close of business on the 10th day 
following the date on which notice of such meeting is first given to shareholders.  Data I/O’s Bylaws also provide that advance notice 
of business to be brought before the 2025 Annual Meeting of Shareholders by a shareholder must be submitted in writing and 
delivered to, or mailed and received by, Data I/O on or before December 6, 2024. 
 
Each notice of a nomination or proposal of business must contain, among other things:  (i) the name and address of the shareholder 
who intends to make the nomination or proposal;  (ii) a representation that the shareholder is a holder of record of stock of Data I/O 
entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to nominate the person or persons 
specified in the notice or to vote at the meeting for the proposal;  (iii) a description of all arrangements or understandings between 
the shareholder and each nominee and any other person or persons (naming such person or persons) pursuant to which the 
nomination or nominations are to be made by the shareholder and any material interest of such shareholder in any proposal to be 
submitted to the meeting; (iv) such other information regarding each nominee or proposal as would be required to be included in a 
proxy statement filed pursuant to the proxy rules of the SEC; and (v) with respect to the nominations, the consent of each nominee to 
serve as a director of Data I/O if elected. 
 
A copy of the full text of the provisions of Data I/O’s Bylaws dealing with shareholder director nominations and proposals is available 
to shareholders from the Secretary of Data I/O upon written request.  The Bylaws may also be accessed online, as a Form 10-K exhibit 
as referenced in our Annual Report on Form 10-K.  SEC rules establish a deadline for submission of shareholder nominations proposals 
that are not intended to be included in Data I/O’s proxy statement with respect to discretionary voting (the “Discretionary Vote 
Deadline”).  The Discretionary Vote Deadline for the 2025 Annual Meeting was February 14, 2025.  If a shareholder gives notice of 
such a nomination or proposal after the Discretionary Vote Deadline, Data I/O’s proxy holders will be allowed to use their discretionary 
voting authority to vote against the shareholder nomination or proposal when and if the proposal is raised at the 2025 Annual Meeting. 
 
Eligible shareholders who intend to have a nomination or proposal considered for inclusion in Data I/O’s proxy materials for 
presentation at the 2026 Annual Meeting must submit the proposal to Data I/O at its principal offices no later than December 5, 2025.  
Shareholders who intend to present a nomination or proposal at the 2026 Annual Meeting without inclusion of such nomination or 
proposal in Data I/O’s proxy materials are required to provide notice of such nomination or proposal to Data I/O no later than February 
13, 2026, as further directed above.   
 
To qualify as an “eligible” shareholder, a shareholder must have been a record or beneficial owner of at least one percent (1%) of 
Data I/O’s outstanding Common Stock, or shares of Common Stock having a market value of at least $2,000, for a period of at least 
one (1) year prior to submitting the proposal, and the shareholder must continue to hold the shares through the date on which the 
meeting is held. 
 
Data I/O reserves the right to reject, rule out of order, or take appropriate action with respect to any nomination or proposal that does 
not comply with these and other applicable requirements, but only after Data I/O has notified the shareholder(s) who have submitted 
the nomination or proposal of the problem and such shareholder(s) have failed to correct it.  This obligation to notify the appropriate 
shareholder(s) does not apply to the failure to submit such nomination or proposal prior to the deadlines discussed above.

STOCKHOLDERS SHARING THE SAME ADDRESS

materials, you may request a separate copy at no cost to you by contacting Investor Relations by email at

SOLICITATION OF PROXIES 
 
The proxy accompanying this Proxy Statement is solicited by the Board of Directors on behalf of the Company.  Proxies may be solicited 
by officers, directors and regular supervisory and executive employees of Data I/O, none of whom will receive any additional

services and, if so, will pay a fee for such services.  Solicitations of proxies may be made personally, or by mail, telephone, telegraph
