Amendment Description	This Amendment No. 1 on Form 10-K/A (the “Amendment”) amends the Annual Report on Form 10-K (the “2025 Form 10-K”) of Data I/O Corporation (the “Company”) for the fiscal year ended December 31, 2025 (the “2025 Fiscal Year”), as filed with the Securities and Exchange Commission (the “SEC”) on April 16, 2026. We are filing this Amendment to amend the following: ·Management’s Discussion and Analysis of Financial Condition and Results of Operations in Item 7 of Part II of the 2025 Form 10-K is hereby amended and restated in its entirety to correct a typographical error of the change in the working capital from 2024 to 2025; ·Various Items in Part III of the 2025 Form 10-K to include the information required by and not included in Part III of the 2025 Form 10-K because we do not intend to file our definitive proxy statement within 120 days of the end of the 2025 Fiscal Year; and ·The Exhibit Index in Item 15 of Part IV of the 2025 Form 10-K is hereby amended and restated in its entirety and currently dated certifications required under Section 302 of the Sarbanes-Oxley Act of 2002 are filed as exhibits to this Amendment. Because no financial statements are contained within this Amendment, we are not filing currently dated certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002. Except as described above, no other changes have been made to the 2025 Form 10-K. The 2025 Form 10-K continues to speak as of the date of the 2025 Form 10-K, and we have not updated the disclosures contained therein to reflect any events which occurred at a date subsequent to the filing of the 2025 Form 10-K other than as expressly indicated in this Amendment.
