## Exhibit 1.01

**EXHIBIT 1.01**

 **Data I/O Corporation's Conflict Minerals Report** 

**in Accordance with Rule 13p-1 under the Securities Exchange Act of 1934** 

This is the Conflict Minerals Report of Data I/O Corporation ("Data I/O," the "Company," "we," "us," or "our") and subsidiaries for calendar year 2025 in accordance with Rule 13p-1 ("Rule 13p-1") under the Securities Exchange Act of 1934 (the "1934 Act"). Please refer to Rule 13p-1, Form SD and the 1934 Act Release No. 34-67716 for definitions to the terms used in this Report, unless otherwise defined herein.

<u>Company and Manufacturing Overview</u>

Data I/O Corporation and its subsidiaries manufacture or contract to manufacture electronic equipment used primarily in our customer's production process for semiconductor programming and handling. We had approximately $21.5 million in revenue in 2025, with 97 employees at the end of 2025. Our manufacturing takes place in Redmond, Washington, USA and Shanghai, China. Our manufacturing primarily consists of final assembly of purchased parts and subassemblies. We contract for the manufacture of certain subassemblies, boards and adapters.

<u>Assessment of Products</u> 

We assessed our products to determine if they contained necessary conflict minerals. We determined our software products did not contain conflict minerals. Our equipment products (PSV7000, PSV5000, Lumen®X2-M4, Lumen®X-M8 programmers, FlashCORE III-M4 programmers, and related options for media handling, vision, laser marking, and adapters) all include one or more necessary conflict minerals.

<u>Process</u>

An internal team sponsored by our Senior Vice President of Operations and driven by our internal supply chain and administrative personnel from each of our USA, China and Germany offices works to gather the information to prepare our Conflict Mineral Report.

We reviewed our conflict mineral policy and the use of a due diligence framework. We developed a supplier contact and survey process and reviewed supply chain risk and mitigation. We maintain a documentation management information system and records retention to comply with the conflict mineral reporting requirements. Steps are described in more detail below.

<u>Conflict Minerals Policy</u> 

Data I/O is committed to working with our global supply chain to achieve greater transparency in our supply chain. Our goal is to source responsibly to manufacture products that do not contain Conflict Minerals that support armed conflict in any of the Covered Countries. As a result, we have established a conflict minerals compliance program that is designed to follow the framework established by the OECD (Organization for Economic Co-operation and Development) in all material respects. As part of that program, we expect that our suppliers conduct conflict minerals due diligence through their supply chains and report their results to us.

<u>Due Diligence Framework</u> 

In conducting our due diligence, we implemented the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas (OECD 2011) ("OECD Framework"), an internationally recognized due diligence frame work, including the related supplements on gold, tin, tantalum and tungsten.

As an electronics manufacturer, Data I/O's due diligence measures were based on the Electronic Industry Citizenship Coalition and Global e-Sustainability ("EICC/GeSI") initiative with the smelters and refiners of conflict minerals who provide those conflict minerals to our suppliers. As a company in the semiconductor programming equipment business, Data I/O is several levels removed from the smelter or actual mining of conflict minerals. Data I/O does not make direct purchases of raw ore or unrefined conflict minerals from smelters or metal traders, or purchases from the Covered Countries. We depend entirely on our multi-tiered supply chain to provide conflict mineral sourcing information.

<u>Data I/O's Due Diligence</u> 

---

| |
|:---|
| Assessed our products as to whether they contained conflict minerals and if so, that the conflict minerals were necessary to the function of the products. All of our equipment products contain one or more necessary conflict minerals.<br>|
| Contacted our suppliers with potential conflict mineral content and interviewed or surveyed them regarding their conflict mineral sourcing as well as reviewing their supply-chain for items including conflict minerals. This involved educating them on the annual SEC reporting requirements and our due diligence expectations.<br>|
| Reasonable country of origin inquiry and due diligence by conducting a supply-chain survey with direct suppliers of materials potentially containing conflict minerals using updated EICC/GeSI Conflict Minerals Reporting Template to identify the smelters and refiners. We requested surveys from a total of 54 suppliers. We received completed surveys from 25; letters of inapplicability from 1; and no response from 29 despite follow-ups. This included follow up on identified discrepancies of reported smelter information, incomplete surveys and no responses to our survey request in our attempt to complete missing information.  |
| Consolidating the survey information and comparing the smelters and refiners identified in the supply-chain survey against the list of smelter facilities which have been identified as "conflict free" by programs such as the RMI's Responsible Minerals Assurance Process (RMAP) program for tantalum, tin, tungsten and gold. Significant variation in the names used by suppliers and missing data in certain surveys of smelter listings from our suppliers impacted our ability to have clarity on the identity of the actual smelter sourced by our supply chain in some instances. |

---

Data I/O does not have a direct relationship with 3TG smelters and refiners, nor do we perform direct audits of these entities that provide our supply chain the 3TG. We rely upon the industry (for example, EICC and CFSI) and larger entities' efforts to influence smelters and refineries to get audited and certified through CFSI's CFS program.

Certain suppliers were able to identify specifically the smelters or refiners of Conflict Minerals that went into parts supplied to us. We typically were not able to receive tailored information relative to the parts we purchased but received generically all possible smelter information for our supplier's entire supply chain. These responses included the names of smelters or refiners listed in the table below. We reviewed the facilities as to being on the CFSI list of smelters and refiners. We were not able to verify that all of the smelters or refiners named were certified Conflict-Free by CSFI, sometimes due to differences in names used by smelters or refiners.

With the exception of the responding suppliers described above, we were unable to identify any of the other smelters or refiners actually in our supply chain. Our identified smelter, facility country and metal table is provided at the bottom of this report.

<u>Conflict Mineral Reporting Conclusion</u>

After exercising the due diligence described above, the Company was unable to determine whether or not its products contain conflict minerals: (1) from recycled or scrap sources as defined in the Conflict Minerals Rule, (2) that did not originate in the Covered Countries, or (3) that did not directly or indirectly finance or benefit armed groups, as defined in the Conflict Minerals Rule, in the Covered Countries.

Our conclusion was due to a lack of information from our suppliers, regarding sourcing of parts and metals with conflict mineral content, required to conclude whether the necessary conflict minerals originated in the Covered Countries and, if so, whether the necessary conflict minerals were from recycle or scrap sources, were DRC conflict free or have not been found to be DRC conflict free.

<u>Independent Audit</u> 

Pursuant to SEC guidance, this Conflict Mineral Report is not audited as none of the Company's products have been found to be "DRC conflict free".

<u>Process Goals and Supplier Expectations</u>

We continue to encourage and follow up with existing and new suppliers on completing the surveys and working with their supply chains to identify the sourcing of conflict minerals. We expect the Company and our suppliers whose products contain conflict minerals to responsibly source and provide information as to the source of conflict minerals, as well as expecting their sub tier suppliers to do the same. We expect that conflict mineral RCOI processes and systems are designed consistent with the Organization for Economic Co-operation and Development Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict- Affected and High Risk-Areas.

If we determine that any supplier is sourcing DRC conflict minerals that benefit armed groups, then we expect the supplier to commit to plan and take corrective action to move to a conflict free source. If suitable action is not taken, we expect to look to alternative sources for the product. Our goal is not to ban procurement of minerals from the DRC and adjoining countries, but to assure procurement from responsible sources in the region. If we determine that any of the components of our products contain minerals from a mine, smelter or facility that is "non-conflict free", we expect to work towards transitioning to products that are "conflict free". Our ability to do so is dependent on the criticality of the specific part and the availability of alternative suppliers.
