2026 Business Framework

Following strong second quarter results and significant progress with the Company’s strategic plan including two planned acquisitions, Data I/O is providing an update to its business framework for 2026. The update is solely based on organic growth and the consolidation of anticipated results for the acquisition in the second half of 2026.

Management Comments

Commenting on the financial results for the second quarter ended June 30, 2026 and recent developments, William Wentworth, President and CEO of Data I/O Corporation, said, “The second quarter marks a clear inflection point in our financial performance and transformation. Revenue of $5.2 million grew 59% sequentially from the first quarter, and bookings of $4.9 million enable meaningful improvements in our operations. As a result, we now have clearer visibility into the strong financial performance we expect in the back half of the year.

“During the first half of the year, we signed six new logos — three from automotive and three from other diversified technology markets, such as robotics and space communications— which shows our platform is resonating well beyond our historical customer base. Our launch of on-site Programming-as-a-Service is gaining traction with strong demand from existing customers. This progress underscores the successful execution of our strategy for top-line diversification and a shift toward higher-value, re-occurring revenue rather than one-time equipment sales.

“We also continued to execute on the strategic plan we laid out at the start of the year. Our expense reduction and improvements to our organic revenue profile are meaningfully lowering our break-even threshold and put profitability within closer reach organically.

“In June we closed a $9 million direct investment, giving us balance sheet strength to advance our growth plan and pursue the acquisitions central to The NEW Data I/O. Our transformational acquisition announced in May is on track with exclusivity extended to the end of August. Once completed, it is expected to nearly double our annual revenue and be accretive to earnings and cash flow.

“In July, on the heels of our planned transformational acquisition, we made another important announcement of our intent to acquire IAR’s embedded software security IP and related assets. This builds on our existing collaboration with IAR and will provide Data I/O with full ownership of the embedded security software and technology, creating an end-to-end security platform for our customers. With regulations such as the EU Cyber Resilience Act increasingly mandating security for all technology devices, this positions Data I/O to extend our value and offer complete and differentiated security provisioning solutions.

"Overall our transformation is moving as planned. The combination of organic business momentum, expense reductions, and progress on two important acquisitions puts Data I/O in position to deliver on our 2026 business framework, which accelerates our growth through greater scale, operational and revenue synergies, and programming platform expansion."

Second Quarter 2026 Financial Results

Net sales in the second quarter 2026 were $5.2 million, as compared with $3.3 million in the first quarter 2026 and $5.9 million in the prior year period. The increased sales sequentially reflect higher first quarter and second quarter bookings. Demand for capital equipment appears to have inflected from a prolonged downward cycle that had been negatively impacted by a realignment of technology spending, with AI-related investments at the forefront and a reassessment of EV capacity and manufacturing impacting the Company’s largest end market of automotive electronics.

Second quarter 2026 bookings were $4.9 million, as compared with $4.2 million in the first quarter 2026. The bookings through the first two quarters of the year is indicative of the current market for programmable devices which has been accelerating within end markets not traditionally targeted by the Company, including edge AI and robotics. Bookings within the automotive electronics market was favorable during the second quarter.

For the second quarter 2026, consumable adapters and services represented 55% of total revenue, providing a stable base of re-occurring revenue. This compares with 81% in the first quarter when total sales were lower. Platform sales represented 45% of total revenue in the second quarter, up from 19% in the first quarter. Backlog on June 30, 2026 was $2.1 million, down from $2.6 million at March 31, 2026. Deferred revenue was $1.1 million on June 30, 2026 and $1.5 million at March 31, 2026.

Gross margin as a percentage of sales was 57.0% in the second quarter 2026, as compared to 49.8% in the second quarter 2025 and 49.5% in the first quarter 2026. The increased gross margin reflects positive mix shift, increased focus on value-based pricing, incremental efficiencies in operations, and improved absorption of labor and overhead costs due to higher revenues. Direct material costs remained relatively steady and consistent with prior periods as the Company continued actively to mitigate the impact of tariffs and other inflationary pressures.

Operating expenses for the second quarter 2026 were $3.7 million, which included approximately $0.5 million in one-time expenses primarily related to optimization efforts at the Company’s operations in the US, consulting and private placement fees, information systems investments and other one-time charges. This compares to operating expenses of $3.8 million in the second quarter 2025 which included approximately $0.5 million in one-time expenses for the Company’s investments in its core programming platform and information systems, as well as for leadership and other human resource transition requirements.*

Operating loss in the second quarter 2026 of ($724,000) on revenues of $5.2 million improved from the loss of ($844,000) on revenues of $5.9 million in the second quarter of 2025. This improved performance reflects operation efficiencies and optimization of the business driving better margins.

Net loss in the second quarter 2026 was ($1,629,000) or ($0.17) per share, compared to net loss of ($742,000) or ($0.08) per share in the second quarter 2025. The increased loss reflects interest expense related to the June 2026 convertible debt issuance of $873,000 which offset a relatively strong quarter for revenue and gross margin and reduced ongoing operating costs.

Adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”), which excludes equity compensation and one-time expenses, was ($488,000) in the second quarter 2026, compared to ($437,000) in the second quarter 2025. Second quarter 2026 Adjusted EBITDA includes $527,000 of one-time expenses largely attributable to restructuring costs, as compared to approximately $480,000 of one-time expenses in the prior year period.*

The Company’s balance sheet and liquidity strengthened with cash at the end of the second quarter 2026 at $10.8 million as compared to $5.7 million on March 31, 2026. The increased cash balance reflects net cash proceeds of $8.3 million from the June 2026 private placement. Data I/O had net working capital of $10.8 million on June 30, 2026, compared with $9.3 on March 31, 2026 and $12.3 million on December 31, 2025. The Company had debt on June 30, 2026 of $6.2 million, reflecting the convertible debt issued as part of the May 2026 private placement. These debentures are classified as short-term debt and are included in the working capital calculation. Subsequent to the end of the second quarter, the convertible debt was converted into preferred equity, eliminating the Company’s debt.
