Redmond, WA – May 14, 2026 -- Data I/O Corporation (NASDAQ: DAIO), the leading global provider of data programming and security provisioning solutions for microcontrollers, security ICs and memory devices, today announced financial results for the first quarter ended March 31, 2026.

First Quarter 2026 and Recent Highlights

2026 Business Framework

Following significant progress with the Company’s strategic plan and the transformational acquisition, Data I/O is providing an update to its business framework for 2026 and is addressing its second quarter results.  The update is solely based on organic growth and the consolidation of anticipated results for the acquisition in the second half of 2026, assuming the closing occurs after June 30, 2026.  Additional inorganic initiatives may be incremental to the framework provided herein.

Management Comments

Commenting on the financial results for the first quarter ended March 31, 2026 and recent developments, William Wentworth, President and CEO of Data I/O Corporation, said, “After nearly a year of strategic planning and organizational optimization, we are extraordinarily excited to have announced a transformational acquisition and major direct investment in the company. The acquisition, valued at $23 million, is expected to be completed by the end of the third quarter and will nearly double our revenues on an annual basis. More importantly, the acquisition checks every significant strategic box we’ve been talking about for the past year that is needed to position Data I/O at the forefront of the device programming industry and expands our addressable market beyond $1 billion annually.

“The acquisition will provide Data I/O with unprecedented scale and is expected to be accretive to our consolidated profit and cash flow. We are acquiring the business from its private equity ownership who expressed confidence in the value of the combined business by taking approximately 15% of the purchase price in Data I/O stock. Our progress and strategic growth plan were further validated through a $9 million direct investment by a single institutional investor who will become our single largest shareholder.

“Beyond these two monumental corporate developments, Data I/O’s first quarter performance reflects a business transition gaining traction on an organic basis. Costs are coming down, customer activity is building, and we are executing against a plan that is tracking nearly one year ahead of schedule. Revenue of $3.3 million and continued negative Adjusted EBITDA are consistent with where we are in the recovery curve. What gives us confidence in the trajectory is the demand environment: customer engagement at the end of 2025 carried through the first three months of 2026 and into the second quarter, with increasing urgency around Edge AI infrastructure build-outs and security provisioning requirements. As we continue to successfully implement new sales models for broader diversification of our business, we expect this to translate into meaningfully higher revenue as we move through the year.

“The structural work of our planned transition is nearing completion. Our German operations were modified early in the first quarter for operational efficiency and to reflect a more diversified global organizational framework which is expected to lead to an approximate reduction in operating expenses of $1 million annually. This was a proactive and deliberate decision to right-size our European cost base against current demand trends while preserving our customer relationships and service capability in the region. The annualized savings from these actions, combined with the broader expense reductions implemented since late 2024, lower our break-even revenue threshold materially and put profitability within reach as revenues grow this year – before the consolidation of our transformational acquisition.

“A key driver of our organic transition is the broad deployment of artificial intelligence across our operations, products, and customer-facing capabilities. We have embedded AI throughout our business — from intelligent customer support tools, to AI-enabled processes that allow us to scale operations, accelerate decision-making, and deliver faster, more responsive service. Our new corporate website, launched in April, was created using AI tools. AI adoption is central to how we operate and one of the primary reasons our transformation is moving faster than we originally anticipated. Ongoing investments in our technology platform and IT infrastructure continue to be of vital importance to our transition.

“The Company’s transition is comprehensive and addresses all operational and administrative functions. To this end, with full transparency in our communications and disclosures, we identified a material weakness in our internal financial controls relating to disaggregated revenue reporting, as detailed in our 2025 Form 10-K with the SEC. We are taking full accountability for bringing our systems into compliance with best practices amid our move to a new ERP system, along with the anticipated acquisition integration. We are addressing our financial controls procedures with urgency and have engaged outside resources in an effort to comply with remediation in 2026.

“The cost for these additional efforts as well as all other investments are largely being offset by operational expense reductions. Cash at quarter end declined from year-end, as expected, and we continued to have no debt until we arranged for the direct investment and acquisition announced in May. Based on the progress we have made on our transition and emerging organic demand, our visibility supports organic growth of approximately 20% in the second quarter 2026 from the first quarter, and from there we look forward to the benefits of the acquisition consolidation and synergies.”

First Quarter 2026 Financial Results

Net sales in the first quarter 2026 were $3.3 million, a reduction from $6.2 million in the first quarter 2025. The reduced sales reflect lower bookings and backlog from the fourth quarter, a function of changing dynamics in the industry. Demand for capital equipment continued to be 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.

First quarter 2026 bookings were $4.2 million, an improvement from $3.1 million in the fourth quarter 2025 but lower than $4.6 million for the first quarter 2025. Despite the increase from the fourth quarter, bookings were impacted by similar market challenges as revenues. Regionally, first quarter 2026 bookings were strongest from customers throughout Europe and Asia, as North America demand declined with the prior year.

For the first quarter 2026, consumable adapters and services represented 81% of total revenue, providing a stable base of re-occurring revenue. Capital equipment sales represented 19% of total revenue in the first quarter. Backlog on March 31, 2026 was $2.6 million, up from $2.3 million at December 31, 2025. Deferred revenue was consistent at $1.5 million on March 31, 2026 and December 31, 2025.

Gross margin as a percentage of sales was 49.5% in the first quarter 2026, as compared to 51.6% in the first quarter 2025. The decrease in gross margin reflects lower absorption of labor and overhead cost amid the lower base of 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 first quarter 2026 were $4.75 million, which included approximately $1.2 million in one-time expenses primarily related to optimization efforts at the Company’s operations in Germany, investments in the core programming platform, information systems and the ongoing transition to a new ERP system. This compares to operating expenses of $3.6 million in the first quarter 2025 which did not include any one-time items.*

Net loss in the first quarter 2026 was ($3.2) million or ($0.34) per share, compared to net loss of ($382,000) or ($0.04) per share in the first quarter 2025. The increased loss reflects lower first quarter 2026 revenue and higher one-time expenses even as ongoing operating costs were reduced from the year earlier period. Both periods include elevated overhead for annual public company expenses that are paid in the first quarter.   

Adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”), which excludes equity compensation and one-time expenses, was ($1.75) million in the first quarter 2026, compared to ($98,000) in the first quarter 2025. First quarter 2026 Adjusted EBITDA includes $1.2 million of one-time expenses, as compared to no one-time expenses in the prior year period.*

The Company’s balance sheet and liquidity remained solid with cash at the end of the first quarter 2026 at $5.7 million as compared to $7.9 million on December 31, 2025.  The decreased cash balance reflects cash expenses paid annually, one-time expenses, technology platform investments, IT spending and increased inventory levels. Data I/O had net working capital of $9.3 million on March 31, 2026, compared with $12.3 million on December 31, 2025. The Company had no debt at March 31, 2026. Subsequent to the end of the first quarter, on May 14 the Company announced a private placement resulting in aggregate gross proceeds of $9 million to the Company.
