Current report

We provide comprehensive data solutions designed to empower organizations across the semiconductor and electronics ecosystems to improve the yield and quality of their products and operational efficiency for increased profitability. We derive revenues from two categories, Platform and Volume-based fees. Our offerings that contribute to Platform revenue are licenses for software (other than Cimetrix runtime licenses) and related software maintenance and technical support services; software-as-a-service (“SaaS”); engineering services; fixed fees associated with Characterization Vehicle systems; and licenses and purchase contracts for DirectScan systems. Volume-based revenue is derived from Cimetrix runtime licenses, secureWISE data, and variable/royalty fees associated with CV systems (sometimes referred to as Gainshare). Our products and services have been sold to integrated device manufacturers (“IDMs”), fabless semiconductor companies, foundries, out-sourced semiconductor assembly and test (“OSATs”), capital equipment manufacturers, and system houses.

Current report

Worldwide economic performance is uneven, and the possibility of a recession persists, leading to uneven demand. Geopolitical tensions and conflicts in various locations around the world have created volatility in the global financial markets and may have further global economic consequences, including potential disruptions of the global supply chain, heightened volatility of commodity and raw material prices, and increased fears of a global recession. Inventories of semiconductor devices remain elevated in some instances. With high inventories and soft demand for some product segments, some semiconductor fab utilization rates are also low and semiconductor capital equipment orders have been impacted for some vendors and market segments. As a result, some purchase cycles, especially for enterprise software and capital equipment and particularly with respect to larger deals, have lengthened in recent years and may continue to do so. Also, we have contractors located in the West Bank and in Israel, who are providing software development and customer technical support services. We have developed contingency plans to use alternative resources to continue serving customers, if needed. Any escalations in these areas could lead to disruptions or reductions in international trade, deter or prevent purchasing activity of customers, and negatively impact our development timelines and customer support (with respect to the conflicts in the Middle East) or China sales (with respect to U.S.-P.R.C. tensions) and financial results in general (with respect to global tensions).

Current report

Beginning with our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 24, 2026, we updated our presentation of revenue categories. The change in presentation of revenues does not change our total revenues or total costs of revenues. The following table presents reclassified historical amounts to conform to the current period’s presentation (in thousands):

Current report

Volume-based revenue decreased $1.3 million for the three months ended March 31, 2026, compared to the same period in 2025, primarily due to decrease in revenue from Gainshare, partially offset by an increase in secureWISE data usage.

Current report

Selling, general, and administrative expenses decreased $5.9 million for the three months ended March 31, 2026, compared to the same period in 2025, primarily due to (i) a $4.3 million decrease in acquisition and integration costs related to the acquisition of SecureWise, (ii) a $1.4 million decrease in personnel-related costs mainly due to lower compensation expense allocated to selling and marketing activities, and stock-based compensation expense, and (iii) a $0.5 million decrease in facilities and IT-related costs, partially offset by a $0.2 million increase in subcontractor expenses.

Current report

The Organization for Economic Co-operation and Development (“OECD”) has a framework to implement a global minimum corporate tax of 15% for companies with global revenue and profits above certain thresholds (referred to as Pillar 2). Although the U.S. has not enacted legislation to implement Pillar 2, certain countries in which we operate have adopted legislation, and other countries are in the process of introducing legislation to implement Pillar 2. The OECD issued new administrative guidance on January 5, 2026, with respect to Pillar 2 which modifies key aspects of the framework for countries to enact in their own laws. Pillar 2 did not have an impact on our condensed consolidated financial statements for the first quarter of 2026 because we do not currently meet the 750 million Euro sales threshold.

Current report

On April 23, 2026, the Company entered into a First Amendment to Credit Agreement (the “Amendment”) with the Lenders and the Agent to amend the Credit Agreement dated as of March 7, 2025. The Amendment increases the Revolving Credit Facility to an aggregate principal amount of $75 million. The Amendment introduces leveraged-based adjustments to the annual Revolving Credit Facility commitment fee during the term of the Credit Agreement. Instead of a flat per annum rate of 0.50%, the Revolving Credit Facility commitment fee will be 0.50% when the total debt to EBITDA ratio is greater than or equal to 2.50 to 1.00, 0.35% when the total debt to EBITDA ratio is less than 2.50 to 1.00 but greater than or equal to 0.50 to 1.00 and 0.20% when the total debt to EBITDA ratio is less than 0.50 to 1.00. All other material terms of the Credit Agreement remain unchanged. Under this facility, $30.0 million is available for the issuance of letters of credit.

Current report

For the three months ended March 31, 2026, net cash flows used in investing activities were $10.5 million related to purchases and prepayments of property and equipment, mainly related to our DirectScan systems.

Previous report

We offer products and services designed to empower organizations across the semiconductor and electronics ecosystems to connect, collect, manage, transfer, and analyze data about design, equipment, manufacturing, and test to improve the yield and quality of their products. We derive revenues from two sources: Analytics and Integrated Yield Ramp. Our offerings combine proprietary software, professional services using proven methodologies, third-party cloud-hosting platforms for software-as-a-service (“SaaS”), electrical measurement hardware tools, and physical intellectual property (“IP”) for integrated circuit (“IC”) designs. We primarily monetize our offerings through license fees and contract fees for professional services and SaaS. In some cases, especially on our historical Integrated Yield Ramp engagements, we also receive a value-based variable fee or royalty, which we call Gainshare. Our products, services, and solutions have been sold to integrated device manufacturers (“IDMs”), fabless semiconductor companies, foundries, out-sourced semiconductor assembly and test (“OSATs”), capital equipment manufacturers, and system houses.

Previous report

On March 7, 2025, we completed the acquisition of SecureWise LLC (“SecureWise”), a Delaware limited liability company (see Note 14,Business Combinations, in the notes to the condensed consolidated financial statements (unaudited) in Part I, Item 1 of this Quarterly Report on Form 10-Q), and added the widely-used, secure, remote secureWISE connectivity solution to our products and services portfolio. We expect this acquisition to also accelerate equipment makers’ ability to derive value from equipment data by enabling them to leverage our Exensio analytics software and to expand the capability of our secure data exchange (“DEX”) outsourced semiconductor assembly and test (“OSAT”) network by allowing equipment makers, fab operators, and fabless companies to collaborate to optimize chip manufacturing and test.

There are other global or business trends that may affect our business opportunities generally as follows:

Previous report

Analytics revenue increased $24.6 million for the nine months ended September 30, 2025, compared to the same period in 2024. The increase in Analytics revenue was primarily driven by an increase in revenues from CV systems, the addition of revenues related to secureWISE products and services, increase in revenues from DFI systems, and an increase in revenues from Cimetrix software licenses, partially offset by a decrease in revenues from Exensio software licenses.

Previous report

Integrated Yield Ramp revenue increased $0.8 million for the three months ended September 30, 2025, compared to the same period in 2024, primarily due to higher Gainshare from increased customer wafer shipments at non-leading-edge nodes, partially offset by decrease in hours worked on fixed fee engagements.

Previous report

Integrated Yield Ramp revenue increased $2.6 million for the nine months ended September 30, 2025, compared to the same period in 2024, primarily due to higher Gainshare from increased customer wafer shipments at non-leading-edge nodes, partially offset by a decrease in hours worked on fixed-fees engagements.

Previous report

Our Integrated Yield Ramp revenue may continue to fluctuate from period to period primarily due to the contribution of Gainshare, which is dependent on many factors that are outside our control, including among others, continued production of ICs by our customers at facilities at which we generate Gainshare, sustained yield improvements by our customers, and whether we enter into new contracts containing Gainshare.

Previous report

The increase in costs of revenues of $5.4 million for the nine months ended September 30, 2025, compared to the same period in 2024, was primarily due to (i) a $2.0 million increase in subcontractor costs, (ii) a $1.8 million increase in personnel-related costs due to worldwide salary increases, higher fringe benefits expense and bonus expense, (iii) a $0.9 million increase in amortization of acquired technology, (iv) a $0.9 million increase in software license and maintenance costs, and (v) a $0.8 million increase in third-party cloud-delivery related costs, partially offset by a $1.2 million decrease in hardware costs.

Previous report

Selling, general, and administrative expenses increased $12.2 million for the nine months ended September 30, 2025, compared to the same period in 2024, primarily due to (i) a $7.0 million increase in personnel-related costs mainly driven by increased headcount, worldwide salary increases, and higher bonus expense and stock-based compensation expense, (ii) a $4.5 million in non-recurring legal, finance, integration, and other costs related to the acquisition of SecureWise, (iii) a $1.3 million increase in subcontractor fees, (iv) a $0.7 million increase in travel expense, (v) $0.3 million increase in facilities and IT-related costs, including shipping costs and depreciation expense, and (vi) a $0.3 million increase in third-party cloud-services related costs, partially offset by a $2.0 million decrease in legal and professional fees.

Previous report

Other income (expense), net decreased $3.7 million for the nine months ended September 30, 2025, compared to the same period in 2024, primarily due to (i) a $3.4 million decrease in interest income from cash, cash equivalents and short-term investments, and (ii) $1.1 million net unfavorable fluctuations in foreign currency exchange rates, partially offset by a $0.6 million recovery from previously written-off property and equipment.

Previous report

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the United States. The OBBBA makes permanent key elements of the Tax Cuts and Jobs Act, including 100% bonus depreciation, domestic research cost expensing, and the business interest expense limitation. ASC 740, Income Taxes, requires the effects of changes in tax rates and laws on deferred tax balances to be recognized in the period in which the legislation is enacted. We completed our initial assessment of the OBBBA corporate tax provisions during the third quarter of 2025. OBBBA contained U.S. corporate tax provisions under which the Company elected to expense U.S. incurred research or experimental expenditures immediately. As a result of these elections, we anticipate a favorable cash tax benefit of approximately $0.9 million and reduction of effective tax rate by approximately 19% in 2025.

Previous report

Cash flows provided by operating activities during the nine months ended September 30, 2025, consisted of a net loss, adjusted for certain non-cash items which primarily consisted of depreciation and amortization, stock-based compensation expense, amortization of acquired intangible expense, amortization of costs capitalized to obtain revenue contracts, net accretion of discounts on short-term investments, accretion of unguaranteed residual assets, and net change in operating assets and liabilities.

Previous report

Net cash flows used in investing activities were $127.6 million for the nine months ended September 30, 2025, compared to net cash flows provided by investing activities of $0.2 million for the nine months ended September 30, 2024.

Previous report

For the nine months ended September 30, 2024, net cash flows provided by investing activities primarily related to proceeds from maturities and sales of short-term investments of $57.1 million, partially offset by purchases of short-term investments of $43.1 million, purchases of property and equipment of $11.9 million primarily related to our DFI systems, and purchase of a convertible promissory note of $2.0 million.

Previous wording

Certain trends may affect our Analytics revenue specifically. In particular, the confluence of Industry 4.0 (i.e. the fourth industrial revolution, or the automation and data exchange in manufacturing technologies and processes) and cloud computing (i.e. the on-demand availability of computing resources and data storage without direct active management by the user) is driving increased innovation in semiconductor and electronics manufacturing and analytics, as well as in the organization of information technology (“IT”) networks and computing at semiconductor and electronics companies across the ecosystem. First, the ubiquity of wireless connectivity and sensor technology enables any manufacturing company to augment its factories and visualize its entire production line. In parallel, the cost per terabyte of data storage has generally decreased over time. The combination of these two trends means that more data is collected and stored than ever before. Further, semiconductor companies are striving to analyze these very large data sets in real-time to make rapid decisions that measurably improve manufacturing efficiency and quality. In parallel, the traditional practice of on-site data storage, even for highly sensitive data, is changing. The ability to cost-effectively and securely store, analyze, and retrieve massive quantities of data from the cloud versus on-premise enables data to be utilized across a much broader population of users, frequently resulting in greater demands on analytics programs. The combination of these latter two trends means that cloud-based, analytics programs that effectively manage identity management, physical security, and data protection are increasingly in demand for insights and efficiencies across the organizations of these companies. We believe that all these trends will continue for the next few years, and the challenges involved in adopting Industry 4.0 and secure cloud computing will create opportunities for our combination of advanced analytics capabilities, proven and established supporting infrastructure, and professional services to configure our products to meet customers’ specialized needs.

Other trends may continue to affect our Characterization services business and Integrated Yield Ramp revenue specifically. For example, semiconductor manufacturers may experience lower wafer shipments due to weakness in the global economy, which would negatively impact the gainshare component of our Integrated Yield Ramp revenue. The logic foundry market at the leading-edge nodes, such as 5nm and smaller, underwent significant change over the past few years. The leading foundry continues to dominate market share. This trend will likely continue to impact our Characterization services business on these nodes. We expect most logic foundries to invest in derivatives of older process nodes, such as 14nm, to extract additional value as many of their customers will not move to advanced nodes due to either technological barriers or restrictive economics. Foundries that participate at leading edge nodes are expected to continue to invest in new technologies such as memory, 2.5D and 3D packaging, extreme ultraviolet lithography, and 3D architectures such as backside power and gate-all-around transistors, as well as new innovations in process control and variability management. We expect China’s investment in semiconductors to continue. Compliance with changing U.S. export restrictions limit our possible business with Chinese semiconductor manufacturers on advanced nodes. As a result of these market developments, we have chosen to focus our resources and investments in products (including differentiated data), services, and solutions for analytics.

Current wording

The logic foundry market at the leading-edge nodes, such as 7nm, 5nm, and smaller, underwent significant change over the past few years. The leading foundry continues to dominate market share. This trend will likely continue to impact our Characterization services business on these nodes. We expect most logic foundries to invest in derivatives of older process nodes, such as 28nm and 14nm, to extract additional value as many of their customers will not move to advanced nodes due to either technological barriers or restrictive economics. Foundries that participate at leading edge nodes are expected to continue to invest in new technologies such as memory, packaging, and multi-patterned and extreme ultraviolet lithography, as well as new innovations in process control and variability management. We expect China’s investment in semiconductors to continue. Compliance with changing U.S. export restrictions limit our possible business with Chinese semiconductor manufacturers on advanced nodes. Further, trade conflict through exchange of tariffs and other retaliatory actions are expected to impact worldwide supply chains, increase prices and put downward pressure on economic activity, and could negatively affect our future sales in various geographic markets. The uncertainty caused by these regulations and the potential for additional future restrictions could negatively affect our future sales, including in but not limited to the People’s Republic of China (“P.R.C.”) market. Some customers in the P.R.C. have expressed concern about the potential for supply chain disruption due to the U.S. government’s changing export controls impacting their purchase, or in some case restricting their ability to purchase, certain U.S. goods. Based on our current assessments, we expect the near-term impact of these evolving trade restrictions on our business to be limited.
