For the three and nine months ended September 30, 2025 and 2024, there were no material realized or unrealized gains or losses, either individually or in the aggregate. See "Contract Balances" section of Note 2, "Revenue from Contracts with Customers." The Company had net investments in sales-type leases for its DirectScan system and CV system assets. The following table summarizes the components of the net investments in sales-type leases in the Consolidated Balance Sheets (in thousands): December 31, 2025 2024 Present value of lease receivables $ 10,890 $ 13,238 Less: Contract liability — (3,235 ) Net lease receivables 10,890 10,003 Unguaranteed residual assets 10,946 7,749 Total net investments in sales-type leases $ 21,836 $ 17,752 Reported as: Current (included in Prepaid expenses and other current assets) $ 14,248 $ 4,526 Non-current (included in Other non-current assets) 7,588 13,226 Total net investments in sales-type leases $ 21,836 $ 17,752 In August 2024, the Company purchased a $2.0 million non-marketable convertible promissory note from an unrelated third party (the “convertible note”). The convertible note bears a 5% interest rate annually and will mature in August 2026. Recurring revenue is comprised of revenue that either recurs on a regular schedule (e.g., SaaS and other services and time-based licenses) or is a type of revenue that generally has often re-occurred in the past (e.g., Cimetrix runtime licenses, secureWISE data, and Gainshare), and that is not Upfront revenue. Though these types of revenue have re-occurred in the past, past events are not necessarily indicative of future results and no assurance can be provided that they will occur in the future. Upfront revenue is comprised of revenue from Exensio perpetual licenses, certain CV test chip designs, and sales-type leases for and sales of hardware. Calculated using the rate implicit in the lease determined for each lease. See Note 5, "Other Non-Current Assets." See "Accounts Receivable" section of Note 1, "Description of Business and Summary of Significant Accounting Policies." See "Costs to Obtain or Fulfill a Contract" section of Note 2, "Revenue from Contracts with Customers." Additions to the accounts receivable reserve for credit losses are charged to bad debt expense. Includes assets deployed at customer sites which could be outside the U.S. Leases with an initial term of 12 months or less are not recorded on the Consolidated Balance Sheets, and the Company recognizes lease expense for these leases on a straight-line basis over the lease term. Variable lease expense for the periods presented primarily included common area maintenance charges. Calculated using incremental borrowing interest rate for each lease.

Services

Our services are almost always sold together with, or to support, our products and include the following:

Software-as-a-Service – We provide services to make our Exensio software available to our customers via the Internet, generally hosted by third-party providers. SaaS is considered part of cloud computing since the software is hosted on the Internet, or the “cloud.” Since our SaaS applications are accessed from a remote server rather than installed on individual machines, it is easier to maintain. For example, when the remote software is updated, the customer’s interface is also updated for all users. Cloud computing is designed to eliminate incompatibilities between different software versions and allow us to make incremental updates without requiring software downloads. Additionally, our customers can save data to a central online location, which is designed to allow increased project collaboration. As part of these services, we also typically provide hosted management services for the software and the customer’s data stored in our cloud. These services include environment set-up and configuration, system health monitoring, data integration maintenance, integration monitoring, system updates, security, and data upload/download, and license administration.

Sales and Marketing

Our sales strategy is primarily to pursue targeted accounts through a combination of our direct sales force, our service teams, and strategic alliances. After we are engaged by a customer and early in the services process, our engineers seek to establish relationships in the organization and gain an understanding of our customers’ business issues. Our direct sales and service teams combine their efforts to deepen our customer relationships by expanding our penetration across customers’ products, processes, and technologies. This close working relationship with each customer has the added benefit of helping us to identify new product areas and technologies in which we should next focus our research and

Our system integration services can also include data cleaning and monitoring services. One requirement of big data analytics is to have clean, harmonized data to analyze. This service offering outsources the data wrangling and management effort to free the customer to focus their efforts on analysis, enabling a greater return on investment to the company than data management. We also provide services to create CV test chips, pdFastTest and eProbe test programs, analysis templates, and other professional services to help customers achieve specific outcomes using our products. Our CV design services are designed to characterize key product and/~~agents~~or process elements into CV test structures. We provide these services, typically together with all elements of our CV system, to foundry customers in ~~various~~connection ~~locations~~with new process technology development and/or yield ramp. In Characterization engagements, which sometimes include our DirectScan system, our services generally also include the analysis of the electrical test results generated by our systems and summary findings and recommendations to ~~augment~~the ~~direct~~customer. We ~~sales~~provide inapplication ~~certain~~engineering ~~territories~~services to design and build recipes for our tool, which involves configuring the tool for the type of product wafer, die size and location, target inspection sites within die, which can include specific DUTs to inspect and their location, as well as the parameters to flag a DUT as an outlier. Our service professionals bring together experience from semiconductor manufacturing and test operations, big data analytics, and AI/ML algorithms to help customers with designing and implementing unique Characterization Vehicle test chips, supporting new product introductions by rapidly identifying root causes of yield detractors, or integrating and aligning manufacturing data from different sources to drive predictive analytics to improve product yield and quality. Our value realization services aim to deliver on the promise of Industry 4.0 by integrating the data generated from sensor-based machines, and connecting them to a big data analytics and machine learning environment that can visualize entire production lines and help take actions that can improve business results.

Sales and Marketing

Our sales strategy is primarily to pursue targeted accounts through a combination of our direct sales force, our service teams, and strategic alliances. After we are engaged by a customer and early in the services process, our engineers seek to establish relationships in the organization and gain an understanding of our customers’ business issues. Our direct sales and service teams combine their efforts to deepen our customer relationships by expanding our penetration across customers’ products, processes, and technologies. This working relationship with each customer has the added benefit of helping us to identify new product areas and technologies in which we should next focus our research and development efforts. From time-to-time, we use sales representatives/agents in various locations to augment direct sales in certain territories.

We are focused on continuing to establish strategic alliances with process licensors, vendors in the electronic design automation software, capital equipment for IC production, and test silicon IP and mask-making software segments to create and take advantage of sales channel and co-marketing opportunities. Additionally, we are focused on continuing to form relationships with key value chain participants, including foundries and OSATs, to provide services and value across the manufacturing supply chain.

Research and Development

Our research and development focuses on developing and introducing new proprietary technologies or enhanced capabilities for our comprehensive platform, including our ~~Exensio~~ software, ~~Cimetrix connectivity~~ and ~~control products~~hardware, and ~~DFI and CV systems, as well as other software products and enhancements to our existing solutions, such as field applications for DFI and CV and~~ new applications targeted to inter-operate with strategic partner products. We use a rapid-prototyping paradigm in the context of ~~the~~ customer ~~engagement~~engagements to achieve these goals. We have made, and expect to continue to make, substantial investments in research and development. The complexity of our technologies requires expertise in standards, physical IC design and layout, transistor design and semiconductor physics, semiconductor process integration, numerical algorithms, e-beam technology, hardware, statistics, networking, security, and software development. We ~~believe~~are ~~that~~focused ~~our~~on ~~team of engineers will continue~~ continuing to advance our market and technological leadership. We conduct in-house training for our engineers in certain technical areas. Our training also extends to focusing on ways to enhance customer service skills. Although it fluctuates, we can have up to one quarter of our research and development engineers assigned to one or more projects, partnered with solution services engineers, in a deliberate strategy to provide direct feedback between technology development and customer needs. We also utilize a variety of skilled independent contractors for specialized development.

Governmental Regulations

We are subject to a variety of federal, state, local and foreign laws and regulations relating to our business and operations, including those related to trade controls, anti-corruption, anti-bribery, data privacy, data protection, use of AI, antitrust, competition, employment, income taxes, and the environment. For additional information regarding risks related to laws and regulations, including existing restrictions imposed by BIS, as well as international operations, see Item 1A, “Risk Factors.”

Trade

A large percentage of our software products are not of U.S. origin and not generally subject to the U.S. Export Administration Regulations (“EAR”) when not located in the U.S. Our standard operations include development, distribution processes, software download sites, and professional service centers and processes located in various geographies around the world to better serve our customers. We are subject to laws and regulations inof the United States and other jurisdictions ~~concerning~~as ~~these~~applicable to operations, ~~with~~products, ~~respect~~services, toand ~~certain~~access ofby ~~our~~certain ~~products~~foreign ~~and~~nationals ~~services~~in ~~outside~~ the United States and toother ~~foreign nationals~~locations, including the EAR, other export controls, tariffs, trade protection measures, sanctions, U.S. outbound investment controls with respect to certain countries, and other trade regulations.

The Bureau of Industry and Security (“BIS”) of the U.S. Department of Commerce has placed certain entities on and frequently adds entities to the “Entity List,” which restricts supply of items to or in connection with the named entities and impacts our ability to transact business with certain customers. BIS recently extended controls to renewal licenses for certain lawfully delivered products that would have changed status under new regulations and designations, causing us to decline certain renewals. In Fall 2025, BIS extended Entity List restrictions to non-listed foreign companies owned 50% or more by parties subject to the Entity List restrictions. This would extend restrictions to a significant number of companies with respect to items that are subject to the EAR. BIS has suspended this rule until November 2026.

Trade regulations limiting or banning sales into certain countries or to certain companies, including economic and financial sanctions and trade embargoes administered and enforced by the U.S. Department of the Treasury’s Office of Foreign Assets Control (“OFAC”), have impacted our ability to transact business in certain countries and with certain customers. Future trade regulations may also impact our ability to transact business with certain customers and in certain countries and may restrict certain non-U.S. person employees from performing their duties at PDF without first obtaining appropriate authorization if their duties involve an export, reexport, or transfer of export-controlled technology. 12

Future trade regulations may also impact our ability to transact business with certain customers and in certain countries and may restrict certain non-U.S. person employees from performing their duties for us without first obtaining appropriate authorization, if their duties involve an export, reexport, or transfer of export-controlled technology.

Anti-corruption and anti-bribery

We are subject to laws and regulations in the United States and other jurisdictions as applicable concerning anti-corruption and anti-bribery, including the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act, which prohibit corrupt payments to governmental officials and bribes to other persons.

Data privacy and data protection

We are subject to laws and regulations in the United States and other jurisdictions governing data privacy and data protection,. ~~including~~This includes laws in locations where we have operations and customers, such as Japan, China, and the EU/UK, which regulate our collection, handling, and use of personal information. These laws and regulations to which we are subject are complex and may change or develop over time, sometimes with limited or no advance notice. Developments or other changes in laws or regulations or how they are interpreted or enforced have had, and may continue to have, a negative impact on our business and increase our compliance-related expenditures.

Artificial intelligence

The ~~regulatory framework governing the use of~~ AI, including machine learning and automated decision-making technologies (“AI Technologies”), that we use in our operations or for software development or build into our software products is ~~rapidly~~subject ~~evolving.~~to ~~Many~~various state, federal, ~~state~~and international laws and ~~foreign~~regulations, ~~government~~which ~~bodies~~continue to evolve. Existing legal regimes (e.g., relating to data privacy) continue to regulate certain aspects of AI Technologies, and ~~agencies~~new laws regulating AI Technologies continue to be enacted around the world. As of 2025, U.S. federal and state approaches remain fragmented, with varying definitions, scopes, and enforcement mechanisms. While several measures have ~~introduced~~focused initially on consumer‑facing or ~~are~~public‑sector ~~currently~~applications, ~~considering~~their ~~additional~~underlying ~~laws~~concepts—such as accountability, transparency, and ~~regulations~~human oversight—may have broader implications across commercial and industrial uses of AI. In the EU, the focus during 2025 shifted from legislative adoption to implementation. Other jurisdictions continue to advance AI‑specific regulatory frameworks with varying approaches: from prescriptive, enforceable controls in China, to framework‑level statutes in Japan and Taiwan (with Japan emphasizing voluntary, guidance‑led compliance and Taiwan establishing statutory principles for future measures), alongside more formal statutory oversight emerging in South Korea. In sum, these developments together contribute to a fragmented and evolving global regulatory landscape for artificial intelligence that may impact our ability to use, develop, and commercialize AI Technologies in the future.

Already, certain existing legal regimes (e.g., relating to data privacy) regulate certain aspects of AI Technologies, and new laws regulating AI Technologies have been enacted in China, the United States, and the European Union. In the United States, the Trump administration has rescinded an executive order relating to AI Technologies that was previously implemented by the Biden administration and may continue to rescind other existing federal orders and/or administrative policies relating to AI Technologies, or may implement new executive orders and/or other rule-making relating to AI Technologies in the future. U.S. legislation is also advancing at the state level. For example, the California Privacy Protection Agency is currently in the process of finalizing regulations under the California Consumer Privacy Act regarding the use of automated decision-making. The EU Artificial Intelligence Act (the “EU AI Act”) applies to companies that develop, use and/or provide AI in the EU and – depending on the AI use case - includes requirements around transparency, conformity assessments and monitoring, risk assessments, human oversight, security, accuracy, general purpose AI and foundation models, and fines for breach of up to 7% of worldwide annual revenues. Such additional regulations may impact our ability to develop, use and commercialize AI Technologies in the future.

For additional information regarding risks related to laws and regulations, including existing restrictions imposed by BIS, as well as international operations, see Item 1A, “Risk Factors.”

Competition

We believe that our solutions compare favorably with respect to competition because we have demonstrated results and reputation, strong core technology, ability to create innovative technology, and ability to implement solutions for new technology and product generations. Further, we believe IC companies benefit from our combination of big data management infrastructure, AI/ML-based analytics engines, and products that generate and collect differentiated data that enrich the analytics process.

We face competition regarding different elements of our products and services portfolio from the following sources and companies:

● indirect competition from internal groups at IC companies that may choose to develop their own test chips or software analytics solutions internally typically by using various commercially-available, general-purpose software, including for example, Tableau from Salesforce, Inc., ~~TIBCO~~Spotfire from Cloud Software Group, Snowflake, Inc., Databricks, Inc.; and,

o connectivity software or integration products/services supporting factory equipment connectivity or control needs of customers, such as PEER Group, Inc., Kontron AIS, GmbH, Yokogawa Electric Corp., Advantest Corporation, ~~and~~ Kornic Automation Co. Ltd., and Tracces by Capgemini SE.

See the discussions in “Risk Factors” under Item 1A for more information about risks associated with our competition.

Human Capital Management

We believe that our future success will depend, in part, on our continued ability to hire and retain qualified management, sales, and technical employees. Consequently, we seek to engage in sound ethical and organizational governance, and promote business ethics and integrity. At the Board of Directors level, our Compensation and Human Capital Management Committee is tasked with oversight of the development, implementation and effectiveness of our policies and strategies relating to human capital management, including strategies regarding recruiting, selection, career development and progression, and employment practices.

As of December 31, ~~2024~~2025, we had ~~539~~ 600 employees worldwide, including ~~174~~ 180 field application engineers, ~~189~~ 225 in research and development, ~~113~~ 135 in sales and marketing, and 63 60 in general and administrative functions. Of these employees, ~~321~~ 364 are located in the United States, ~~180~~and Canada, 197 in Asia, and 38 39 in Europe. None of our employees are represented by a labor union. Our employees in France and Italy are subject to collective bargaining agreements in those countries.

Talent Development

We believe the development and growth of our employees is crucial to further enhance the talent we have today and to foster the right skill sets for our future for our long-term success. As such, we encourage mentorship and engaging in development opportunities. We also conduct in-house training for our engineers in certain technical areas and provide access to an online training platform for all of our employees. Further, we fund attendance at continuing education courses, symposia, and participation in professional organizations.

Employee Engagement

Employee engagement is crucial for the overall health of the organization. In 2024, we conducted a survey of all our employees to assess overall employee engagement.

In addition to our efforts to address employee engagement, we are committed to supporting our employees and creating an engaged workforce by prioritizing the items below:

•personal growth through training and development;

•recognizing and rewarding our people for their commitment to our values and our organization;

Table of Contents

•flexible work locations and schedules; and

•providing a sense of organizational community by hosting in-person events where our people can gather and connect.

Item 1A. Risk Factors

A description of the risk factors associated with our business is set forth below. Some of these risks are highlighted in the following discussion, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, Legal Proceedings, and Quantitative and Qualitative Disclosures About Market Risk. The occurrence of any of these risks or additional risks and uncertainties not presently known to us or that we currently believe to be immaterial could materially and adversely affect our business, operating results, financial condition, and stock price. These risks and uncertainties could cause our actual results to differ materially from the results contemplated by the forward-looking statements contained in this report. Investors should carefully consider all relevant risks and uncertainties before investing in our common stock.

Risks Associated with Our Business

Our significant research and development investment may nonetheless fail to keep pace with technological changes or ensure that our offerings meet market needs, which would adversely impact our business, financial condition, or results of operations.

As part of the evolution of our business, we have made and continue to make substantial investments in research and development of our products and services, including, in particular, our ~~DFI~~DirectScan system and Exensio, Sapience, and ~~Sapience~~secureWISE software. New competitors, changes to existing contracts with licensed technology, any companies, products, or services that we may acquire, technological advances in the semiconductor industry and adjacent markets, and other competitive factors have required us and may continue to require us to invest significantly greater resources than we anticipated. For example, following our acquisition in July 2023 of Lantern Machinery Analytics, Inc., an early-stage battery solutions provider, we invested in research and development to expand the application of our existing products and services to battery manufacturers. If we do not anticipate and address technological changes in our industry or our offerings fail to meet market demand, the corresponding additional revenue we anticipate may not materialize, we may not recoup our investment or capture the market share we anticipate, we may lose our competitive position, and our products may become obsolete, which would adversely impact our business, financial condition and results of operations. Additionally, our periodic research and development expenses may be independent of our level of revenue, which could negatively impact our financial results.

If we enable access to hosted software or begin performing services ahead of a signed contract or amendment to an existing contract, and the final terms are not as favorable as we expected or the customer delays entering, or decides not to enter, into the contract or amendment, our results of operations could be harmed in the short term or overall and recognition of related revenue could be delayed or not occur at all.

If we are unable to close new engagements or amendments to existing contracts on terms favorable to us, in a timely manner, or at all, including in cases where we have incurred costs or assigned engineering resources in advance of entering into such engagements or amendments, our revenues may fall short of expectations and other revenue opportunities may have been delayed or lost. Further, the timing and length of negotiations required to enter into agreements with our customers and the enforcement of our complex contractual provisions is difficult to predict. If we do not successfully negotiate certain key complex contractual provisions, if there are disputes regarding such provisions, or if they are not enforceable as we intended, our revenues and results of operations would suffer. Further, our customers sometimes delay starting negotiations until they begin developing a new process, have a need for a new product, or experience specific yield issues. This means that, in certain instances, we have continued, and may continue to provide technology and services under preliminary documentation before executing the final contract. In these cases, we would not recognize revenue and may defer associated costs until execution of a final contract, which, if significant, could negatively impact our results of operations in the periods before we execute a final contract. Further, if we were to incur significant costs and then fail to enter into a final contract, we would have to write-off such deferred costs in the period in which the negotiations ended, which would increase our costs and expenses and could result in significant operating losses.

We rely on sole-source providers for certain software as well as for specialized parts for our ~~eProbe~~DirectScan ~~hardware~~system and supply-chain delays or disruptions could increase our costs or impact our ability to provide complete software solutions or to build additional hardware tools or meet customer expectations or deadlines, which could result in lost sales and lower earnings.

We provide some enabling technology under license and support from sole-source providers and some of our vendors provide highly specialized, differentiated products and services related to our ~~eProbe~~DirectScan system. In the event these licensors or vendors delay or discontinue providing such products and services to us, it may be difficult and costly or impossible for us to replace such suppliers or parts. In the case of licensed software, this could impact our ability to grow our sales or to meet the support expectations of our customers and we may need to resort to legal action, which could limit our future sales, harm our reputation, increase our costs, and harm our earnings. For example, in November 2023, a provider of enabling technology abruptly stopped providing maintenance and support of their software product to us. As a result, we resorted to legal action, which caused us to incur increased legal expenses beginning in the fourth quarter of 2023. The matter is ongoing, and the long-term impact of this provider’s actions on our business and our customers is unknown at this time. In the case of vendors related to our eProbe tool, such disruptions or delays could delay or stop our ability to complete and deliver our ~~DFI~~ DirectScan systems as currently designed to our customers, which would negatively impact our bookings and revenue related to such systems. In addition, such delays or disruptions to our supply chain could significantly increase our component costs, or personnel-related costs if we need to build a replacement solution in the case of certain software elements, and could impact our ability to build future generations or models of our eProbe tools, any of which would decrease or delay our sales, earnings, and liquidity and could otherwise adversely affect our business and result in increased costs. Such a delay or disruption could occur as a result of any number of events, including, but not limited to: failure to comply with existing contracts, higher priority alternative buyers, inflation and global interest rates increasing component costs, a closure or slowdown at our suppliers’ plants or shipping delays, market shortages for critical components, increases in prices, the imposition of regulations, quotas, embargoes or tariffs on components or our products, labor stoppages or shortages, our suppliers’ supply chain disruptions, third-party interference, cyberattacks, severe weather conditions including the adverse effects of climate change-related events, geopolitical developments, war or terrorism, and disruptions in utilities and other services. In addition, the development, licensing, or acquisition of new products in the future may increase the complexity of supply chain management. Failure to effectively manage our supply of components and products could adversely affect our business.

Our fixed-fee services for product or system installations/configurations or specified upgrades may take longer than budgeted or need to be rescoped, which could slow our revenue recognition and may result in a lost contract or a claim of breach by our customers, which would negatively affect our financial and operating results.

Our fixed-fee services, including for Characterization and enterprise software deployments, require a team of engineers to collaborate with our customers to address complex issues by using our software and other technologies, and the installation and configuration of our software into our customers’ fabrication and test/assembly facilities requires experienced engineers working with our customers on active foundry and test/assembly equipment. We must accurately estimate the amount of time and resources needed to complete these types of services to determine when the engineers will be able to commence their next engagement. In addition, our accounting for contracts with such services, which generate fixed fees, sometimes requires adjustments to profit and loss based on revised estimates during the performance of the contract. These adjustments may have a material effect on our results of operations in the period in which they are made. The estimates giving rise to these risks, which are inherent in fixed-price contracts, include the forecasting of costs and schedules, and contract revenues related to contract performance. Services for system installations/configurations or specified upgrades may take longer than budgeted or need to be rescoped, which could impact our ability to deliver services on schedule. If we fail to meet a customer’s expectations or fixed milestones or delivery timelines, the customer could terminate their contract with us or claim that we breached our obligations, which could negatively affect our financial and operating results.

Our ability to sell our products, systems, and solutions depends in part on the quality of our support and services offerings, and the failure to offer high-quality support and services could negatively affect our sales and results of operations.

Once our products are integrated within our customers’ hardware and software systems, our customers may depend on our support organization to resolve any issues relating to our products. Further, in connection with delivering our SaaS Services, which requires us to maintain adequate server hardware and internet infrastructure, including system redundancies, we are required to meet contractual uptime obligations. A high level of system and support is critical for the successful marketing and sale of our products. If we do not effectively provide subscription access to our SaaS customers, assist our customers in deploying our products, succeed in helping our customers quickly resolve post-deployment issues, and provide effective on-going support and the privacy and data security capabilities required by our customers, we may face contractual penalties or customers may not renew subscriptions or services in the future, which would negatively impact our results of operations. In addition, due to our international operations, our system and support organization faces challenges associated with delivering support, hours that support is available, training, and documentation where the user’s native language may not be English. If we fail to maintain high-quality support and services or fail to adequately address our customers’ support needs, our customers may choose our competitors’ products instead of ours, which would negatively affect our revenues and results of operations.

If we do not effectively provide subscription access to our SaaS customers, assist our customers in deploying our products, succeed in helping our customers quickly resolve post-deployment issues, and provide effective on-going support and the privacy and data security capabilities required by our customers, we may face contractual penalties or customers may not renew subscriptions or services in the future, which would negatively impact our results of operations. In addition, due to our international operations, our system and support organization faces challenges associated with delivering support, hours that support is available, training, and documentation where the user’s native language may not be English. If we fail to maintain high-quality support and services or fail to adequately address our customers’ support needs, our customers may choose our competitors’ products instead of ours, which would negatively affect our revenues and results of operations.

Defects in our software, hardware and other proprietary technologies, and failure to effectively remedy any such defects could decrease our revenue and our competitive market share.

If the software, hardware, or other proprietary technologies we provide to customers contain defects that negatively impact customers’ ability to use our products and services, increase our customers’ cost of goods sold or time-to-market, or damage our customers’ property, such defects could significantly decrease the market acceptance of our products and services and could result in warranty or other claims. We must adequately train our new personnel, especially our customer service and technical support personnel, to effectively and accurately, respond to and support our customers. If we fail to do this, it could lead to dissatisfaction among our customers, which could slow our growth. Further, the cost of support resources required to remedy any defects in our software, hardware and other proprietary technologies could exceed our expectations.

We have and may further incorporate ML, AI and related technologies (“AI Technologies”) in product development, or into our platform, offerings, services and features, and these technologies may become more important in our operations over time. If the content, analyses, recommendations, or other output that AI Technologies assist in producing are or are alleged to be deficient, inaccurate, or imprecise, our business, financial condition, and results of operations may be adversely affected. Any actual or perceived defects with our software, hardware, or other proprietary technologies may also hinder our ability to attract or retain industry partners or customers, leading to a decrease in our revenue. These defects are frequently found during the period following introduction of new software, hardware, or proprietary technologies or enhancements to existing software, hardware, or proprietary technologies, which means that we may not discover the errors or defects until after customer implementation, if at all. If our software, hardware, or other proprietary technologies contain errors or defects, it could require us to expend significant resources to remedy these problems and defend/indemnify claims, which could reduce margins and result in the diversion of technical and other resources from our other customer implementations and development efforts.

Objectionable disclosure of our customers’ confidential information or our failure to comply with our customers’ security rules, including for those related to SaaS access, AI Technology use, or our on-site access, could result in costly litigation, cause us to lose existing and potential customers, or otherwise negatively impact on-going business with existing customers.

In the course of providing SaaS or other services engagements, we may collect customers’ product, process, and test information, personally-identifiable data about their employees needed to administer licenses, and other confidential information. Our customers consider most of this information to be competitively sensitive and, in some cases, require us to comply with strict protection frameworks, including security rules for on-site or remote access to, hosting of, or transfer of their confidential information. As a result of increased regulatory and customer scrutiny of all data processing activities, as well as increasing and evolving regulation of such practices, we have security obligations on how we collect, transfer and use data (including personal data), which could require us to expend money and resources to comply with those requirements, and if compromised, could have a material adverse effect on our business, financial condition, and results of operations, including the potential for regulatory investigations, enforcement actions, lawsuits, and a loss of business and a degradation of our reputation. If we fail to implement industry standard protections and processing procedures, the growing awareness of our customers and potential customers regarding privacy and data security requirements and/or adverse media coverage or regulatory scrutiny could limit the use and adoption of our services. In addition, to avoid potential disclosure of confidential information to competitors, some of our customers may, in the future, ask us not to work with key products or processes, which could limit our revenue opportunities.

If the third-party AI technologies we use for research and development purposes misuse or fail to properly protect the data we input or if an employee inputs our or our customers’ confidential information into an AI system that is not behind our corporate firewall or with which we do not have terms limiting the use of inputs, it may result in the unauthorized disclosure of sensitive, proprietary, or confidential information belonging to us or our customers. For example, if the information input into a third-party AI technology system is used to train the underlying AI models, such inputs could be revealed to others. The third-party AI technologies may also provide outputs that appear to be correct but are incomplete, inaccurate, or otherwise flawed and may lead us to make erroneous decisions or recommendations to customers, which could result in harm to our reputation and competitive position, customer loss, and legal liability.

We generate a significant portion of our revenues from a limited number of customers, and a large percentage of our revenues from one customer, so defaults or decreased business with, or the loss of, any one of these customers, or pricing pressure, or customer consolidation could significantly reduce our revenues or margins and negatively impact our results of operations.

Historically, we have had a small number of large customers that contribute significant revenues. In the year ended December 31, ~~2024~~2025, ~~two~~ three customers accounted for 3153% of our total revenues. We have in the past and could in the future lose a customer due to its decision not to develop or produce its own future process node or not to engage us on future process nodes. We could also lose customers as a result of industry factors, including but not limited to reduced manufacturing volume or consolidation. Consolidation among our customers could also lead to increased customer bargaining power, or reduced customer spending on software and services. Further, new business may be delayed or prevented if a key customer uses its leverage to insist on terms that are worse for us and we delay entering into the contract to negotiate for better terms or decide not to enter into the contract at all, in which case revenue in any particular quarter or year may fail to meet expectations and our reliance on our remaining customers could increase.

Further, if any of our key customers default, declare bankruptcy or otherwise delay or fail to pay amounts owed, or we otherwise have a dispute with any of these customers, our results of operations would be negatively affected in the short term and possibly the long term. For example, ~~excluding~~in ~~contingent fee arrangements~~2019, ~~we incurred substantial expenses related to the arbitration with~~ SMIC New Technology Research & Development (Shanghai) Corporation ~~due~~stopped topaying ~~SMIC’s failure to pay~~ fees due to us under a series of contracts. In ~~2025,~~addition ifto wethe ~~are~~loss ~~awarded~~of ~~any~~ contract ~~fees~~revenue under ~~the~~these ~~arbitration~~contracts after that time, we ~~will~~incurred ~~incur~~significant ~~additional~~ expenses related to ~~legal~~pursuing ~~fees~~our ~~that~~legal ~~are~~rights ~~contingent~~under onthese ~~such~~contracts, aincluding ~~favorable~~$2.5 ~~result,~~million ~~which~~of ~~may~~attorneys’ befees ~~substantial~~incurred ~~depending~~in on the ~~size~~fourth quarter of ~~any award~~2025. The loss of significant expected revenue from any of our key customers would cause significant fluctuations in results of operations because our expenses are fixed in the short term and it takes us a long time to replace customers or reassign resources.

If we do not continuously meet our development milestones of key research and development projects or market adoption of our ~~DFI~~DirectScan system fails to meet our expectations, our future market opportunity and revenues will suffer, and our costs may not be recouped.

We have invested significantly in the design and development of our eProbe tool and related IP. Key customers failing to purchase, renew, or expand the number or use of such systems on our expected timeline or at all will cause our results to miss expectations. Also, if customers are not able to achieve the results they expect using our ~~DFI~~DirectScan system, including new applications, customers may not continue to adopt this system or such applications as we expect, or at all, and we may miss the market opportunity and not recoup our investment. Further, our eProbe tool could cause unexpected damage to wafers or delay processing wafers, which we could be liable for, or which could make customers unwilling to use the tool. If we are not able to create significant interest and show reliable and useful results without significant damage to wafers, our investment may not be recouped and our future results may suffer.

We are required to comply with governmental export and import requirements that could subject us to liability and restrict our ability to sell our products and services, which could impair our ability to compete in international markets.

We are required to comply with export controls and economic sanctions laws and regulations that restrict selling, shipping, or transmitting our products and services, transferring our technology outside the United States, or certain U.S. person activities regarding certain end-users or end-uses. These requirements also restrict domestic release of software and technology to foreign nationals. In addition, we are subject to customs and other import requirements that regulate imports that are important for our business. If we fail to comply with the U.S. Export Administration Regulations (“EAR”) or other U.S. or non-U.S. export or economic sanctions laws and regulations (collectively, “Export Regulations”), we could be subject to substantial civil and criminal penalties, including fines for the Company and the possible loss of the ability to engage in exporting and other international transactions. Due to the nature of our business and technology, Export Regulations may also subject us to governmental inquiries regarding transactions between us and certain foreign entities.

~~Decreases~~Our inVolume-based revenue includes amounts largely determined by variable wafer volumes at manufacturing sites covered by our contracts and, in some cases, determined by the volume of an IC product that our customer is able to sell to its customers. Both of these factors are outside of our control. In recent years, we saw significant reduction in our Volume-based revenue due to these trends. Further, some of our manufacturing customers’ business is largely dependent on customers that use our manufacturing ~~sites~~customer as a second or third source. If those customers consolidate and/or otherwise move the orders to manufacturing facilities not covered by our contracts, or suspend their manufacturing at covered facilities for any reason, including consolidation, our Volume-based revenue will continue to decrease, which could negatively affect our financial results. Further, reduced demand for semiconductor products or protectionist policies like those stemming from the complex relationships among China, Hong Kong, Taiwan, and the United States has from time to time decreased and may continue to decrease the volume of ~~ICs~~wafers ~~that~~and, in some ofcases, products our customers are able to ~~sell~~make toor ~~their~~sell, ~~customers~~which would ~~cause~~also decrease our ~~Integrated~~Volume-based ~~Yield~~revenue. ~~Ramp~~Also, ~~revenue~~our customers may unilaterally decide to ~~suffer~~implement changes to their manufacturing processes during the period that volume is covered by royalty contracts, which could negatively affect yield results and, thus, our Volume-based revenue.

Since we currently work on a small number of large projects at specified manufacturing sites and, in some cases, on specific IC products, our results of operations have been and may continue to be adversely affected by negative changes at those sites or in those products, including slowdowns in manufacturing due to external factors, such as U.S. trade restrictions, tariffs, rising inflation and global interest rates, or continued or worsening supply chain disruptions. Also, if wafer orders from sites covered by our contracts are not secured by our customers, if an end product does not achieve commercial viability, if a process line or, in some cases, a specific product, does not achieve significant increases in yield or sustain significant volume manufacturing during the time we receive royalties, revenues associated with such volumes or products would be negatively impacted. This could significantly reduce our Integrated Yield Ramp revenue and our results of operations could fail to meet expectations. In addition, if we work with two directly competitive manufacturing facilities or products, volume in one may offset volume, and thus any of our related revenue, in the other facility or product.

Our success depends upon our ability to effectively plan and manage our resources and restructure our business through rapidly fluctuating economic and market conditions, which actions may have an adverse effect on our financial and operating results.

Our ability to successfully offer our products and services in a rapidly evolving market requires an effective planning, forecasting, and management process to enable us to appropriately scale and adjust our business and business models in response to fluctuating market opportunities and conditions, which has in the past and could in the future continue to require us to increase headcount, acquire new companies or engage in restructurings from time to time. For example, while we have increased investment in our business by increasing headcount, acquiring companies, and increasing our investment in research and development, sales and marketing, and other parts of our business from time to time, at other times we have undertaken restructuring initiatives to reduce expenses and align our operations with our evolving business needs. Some of our expenses related to such efforts are fixed costs that cannot be rapidly or easily adjusted in response to fluctuations in our business or headcount. Rapid changes in the size, alignment or organization of our workforce, including sales account coverage, could adversely affect our ability to develop and deliver products and services as planned or impair our ability to realize our current or future business and financial objectives. Our ability to capitalize on the market opportunity and achieve cost savings and other benefits from restructuring initiatives within the expected time frame requires significant management input and leadership and is subject to many estimates and assumptions, which are subject to significant economic, competitive and other uncertainties, some of which are beyond our control. If these estimates and assumptions are incorrect, and we are unsuccessful at implementing changes, or if other unforeseen events occur, our business and results of operations could be adversely affected.

Global economic or geopolitical conditions or semiconductor market conditions could materially adversely impact demand for our products and services, decrease our sales, or delay our sales cycle.

Our customers are global semiconductor companies, which means that our operations and performance depend significantly on worldwide economic and geopolitical conditions as well as semiconductor market specific changes. Current global economic conditions and uncertainty about future conditions including war, terrorism, geopolitical uncertainties and other business interruptions could result in damage to, disruption, postponement or cancellation of sales of our products or services on a global or regional basis. Several nations have recently conducted or threatened military or hybrid-warfare operations tied to or affecting operational regions of the semiconductor industry. In the future such conflict could damage participants, disrupt international business, and reduce supply and demand in our industry, including for our products and services. Furthermore, tariffs, trade controls, export and import regulations, tighter credit, higher interest rates, inflationary concerns, large-scale unemployment, negative financial news and/or declines in income or asset values and other macroeconomic factors could have a material adverse effect on demand for our products and services and, accordingly, on our business, results of operations or financial condition and/or vendors with which we do business. For example, the timing of the build-out of the semiconductor market in China depends significantly on governmental funding on both local and national levels and a delay in this funding could negatively affect our revenues. Further, the U.S. federal government has recently stated its intention to change U.S. trade policy, including potentially renegotiating or terminating existing trade agreements and leveraging tariffs. In February 2025, the U.S. imposed additional tariffs on imports from China and announced and subsequently paused implementation of tariffs on imports from Canada and Mexico. The U.S. government has changed policy by imposing or threatening to impose certain additional tariffs expressly in pursuit of foreign policy goals. Some possible tariffs could significantly increase cost of imported goods. These additional tariffs, as well as a government’s adoption of “buy national” policies or retaliation by another government against such tariffs or policies, have introduced significant uncertainty into the market and may affect the prices of and demand for our and our customers’ products. Further, the semiconductor industry historically has been volatile with up cycles and down cycles, due to sudden changes in customers’ manufacturing capacity requirements and spending, which depend in part on capacity utilization, demand for customers’ IC products by consumers, inventory levels relative to demand, and access to affordable capital. As a result of the various factors that affect this volatility, the timing and length of any cycles can be difficult to predict and could be longer than anticipated. Any of these events could negatively affect our revenues and make it challenging or impossible for us to deliver products and services to our customers forecast our operating results, make business decisions, and identify the risks that may affect our business, financial condition and results of operations. Customers with liquidity issues may also lead to additional credit losses.

We face challenges in providing a comprehensive solution outside of the semiconductor industry due to limitations on the business areas in which we can use current third-party licensed technology, which may make it prohibitively expensive to sell our solution for applications outside of our traditional industry.

Since certain of our current software requires commercially-available, third-party programs to run as intended and some of our contracts with licensors limit the industry in which we can resell such third-party programs, we face challenges to provide a comprehensive solution to battery manufacturers. If we or our customers are unable to procure required third-party programs that can be used in connection with our products for battery manufacturing, or the cost to do so is higher than expected, we may miss the market opportunity, which would mean lower sales than expected, or our costs may be higher, which would mean lower earnings than expected. Further, if we are unable to develop a suitable product that is not limited by such third-party restrictions and meets the market’s needs or the costs to do so are higher, or the time required to do so, is longer than expected, we may lose future business opportunities and our results of operations will suffer.

Risks Related to Our Technology

If we fail to protect our IP rights, customers or potential competitors may be able to use our technologies to develop their own solutions, which could weaken our competitive position, reduce our revenues, or increase our costs.

Our success depends largely on the protection of our proprietary technology. Our contractual, patent, copyright, trademark, and trade secret protection may not be effective against any particular threat or in any particular location. Our pending patent applications may not result in issued patents, and even if issued, they may not be sufficiently broad to protect our proprietary technologies. Some foreign countries do not currently provide effective legal protection for IP and our ability to prevent the unauthorized use of our products in those countries is therefore limited. Our trade secrets may also be stolen, otherwise become known, or be independently developed by competitors. Litigation may be necessary from time to time to enforce our IP rights. As a result of any such litigation, we could lose our proprietary rights and incur substantial unexpected operating costs. Litigation could also divert our resources, including our managerial and engineering resources. If we are unable to exclude others from using our proprietary technologies and methods without compensation to us, through litigation or otherwise, it could impede our ability to grow our business and our revenues may suffer.

We and our third-party service providers are exposed to risks related to information technology infrastructure, information management and protection, cybersecurity threats, and cyber incidents; if we or our third-party providers fail to protect confidential information and/or experience a cyber incident, there may be damage to our brand and reputation, material financial penalties, and legal liability.

We are heavily reliant on our systems, hardware, software, technology infrastructure, online sites, networks, and the public cloud to an increasing degree, to provide our products and services to our customers (collectively, “IT Systems”). Additionally, we must frequently expand our IT Systems to meet increasing demand in storage, computing and communication, which results in increased costs. Our IT Systems are expensive to expand and must be highly secure due to the sensitive nature of the information that we, and certain of our third-party providers, collect, maintain and process. This includes information about customers, employees, business partners and others, as well as proprietary information belonging to our business or that of our customers such as trade secrets (collectively, “Confidential Information”).

We face numerous and evolving cybersecurity risks that threaten the confidentiality, integrity and availability of our IT Systems and Confidential Information, including denial-of-service attacks or other cyber-attacks, hacking, “phishing” attacks, computer viruses, ransomware, malware, employee or insider error, malfeasance, social engineering, deep-fake impersonations, physical breaches, or other events or developments that we may be unable to anticipate or fail to mitigate. Bad actors use widely available access to generative AI technology for more sophisticated and frequent cyber-attacks or fraudulent impersonations against us. In addition, any integration of AI in our or any service providers’ operations, products or services is expected to pose new or unknown cybersecurity risks and challenges. These attacks could come from either advanced persistent threat actors, state-sponsored organizations, opportunistic hackers, hacktivists, or other individual organized or unorganized malicious actors. The expense to purchase, update, and configure security information systems to detect and/or neutralize increasingly complex and sophisticated attacks increases our costs and, failure to acquire the right expertise or systems may leave us vulnerable to attacks, which could expose Confidential Information, result in liability and have a negative impact on our reputation and business opportunity. In addition, companies that we acquire may have cybersecurity vulnerabilities and/or unsophisticated security measures, which exposes us to significant cybersecurity, operational, and financial risks. We are also subject to risks related to continued support of our employees’ remote or hybrid work environment, which creates additional information security vulnerabilities and/or magnifies the impact of any disruption in our IT Systems.

Table of Contents

We rely on third-party service providers to enable key services to our customers, including for cloud services, enterprise software, customer support portal software, and co-location computing facilities. We have experienced in the past, and may experience in the future, interruptions in our IT Systems on which our global operations depend or unplanned downtime of the infrastructure that delivers our SaaS. Such an unplanned interruption, even if temporary, could stop SaaS customers from accessing their hosted data or on-premise customers from downloading licensed software or critical security patches, or from accessing our support portal, which could mean that we may not meet our contractual commitments for such services to customers, which could reduce our revenue, incur liability, or result in damage to our reputation and negatively impact future sales. Further, the IT Systems that store and process our and our customers’ Confidential Information is susceptible to continually evolving cybersecurity threats that become more complex over time, especially with the rapid evolution of AI technologies, and may not be recognized until launched against a target, all of which could result in unauthorized access to, or acquisition of, our data, and interruption or disruption of our business.

Cyberattacks are expected to accelerate on a global basis in frequency and magnitude as bad actors are becoming increasingly sophisticated in using techniques and tools that circumvent security controls, evade detection, and remove forensic evidence. In addition, ransomware attacks are becoming increasingly prevalent and severe, and can lead to significant interruptions in our operations, loss of data and income, reputational loss, diversion of funds, and may result in fines, litigation and unwanted media attention. As a result, we and our third-party service providers, with whom we share data, may be unable to anticipate these techniques or attacks or may not implement adequate preventative measures to prevent either unauthorized access to our IT Systems that could compromise Confidential Information or result in a disruption of our services. In particular, like our peers, we are often the target of cyber-attacks by third parties seeking unauthorized access to Confidential Information, or to disrupt our ability to provide services. There can be no assurance that our cybersecurity risk management program and processes, including our policies, controls or procedures, will be fully implemented, complied with or effective in protecting our IT Systems and Confidential Information. Furthermore, given the nature of complex systems, software and services like ours, and the scanning tools that we deploy across our networks and products, we regularly identify and track security vulnerabilities. We are unable to comprehensively apply patches or confirm that measures are in place to mitigate all such vulnerabilities, or that patches will be applied before vulnerabilities are exploited by a threat actor. When we experience a security incident, we have to conduct an investigation and may need to notify individuals, customers, partners, service providers and state, federal or local governmental authorities and regulators in the U.S. or elsewhere around the world. In addition, any controls issues found during security assessment of our systems required by our customers and technical partners may result in disclosure to customers and potential customers and cause customers to re-evaluate their purchasing or renewal decisions, which could cause us to lose sales. Accordingly, any adverse impact to the availability, integrity or confidentiality of our IT Systems or Confidential Information may lead to significant costs and fees for legal advice, investigation support, remediation, and result in legal risk exposure (such as class actions), regulatory investigations and enforcement actions, fines and penalties, damage and harm to our reputation, and impact on our ability to keep and attract customers. Any or all of the foregoing could materially adversely affect our business, results of operations, and financial condition. Our insurance policies may not cover losses incurred in the event our systems or data are comprised, and they are subject to retention amounts that could be substantial. Moreover, we cannot be certain that such insurance policies will continue to be available to us on economically reasonable terms, or at all, or that any insurer will not deny coverage as to any future claim.

We and our customers are subject to laws and regulations concerning data privacy, data security, consumer protection, and advertising and these laws and regulations are continually evolving, which exposes us to potential material risks, including significant liability, negative publicity, and/or an erosion of trust, which could materially adversely affect our business, results of operations, and financial condition.

We collect, use, store or disclose (collectively, “process”) information that relates to individuals and/or constitutes “personal data,” “personal information,” “personally identifiable information,” or similar terms under applicable data privacy laws (collectively, “Personal Information”), including from employees and customers, in connection with the operation of our business. The Personal Information we process is subject to an increasing number of federal, state, local and non-U.S. laws, rules, regulations, industry standards, and other requirements regarding privacy and data security, including in some cases the EU General Data Protection Regulation, the UK General Data Protection Regulation and the UK Data Protection Act, as well as contractual commitments with our customers. These laws require us to adhere to certain disclosure restrictions and deletion obligations with respect to Personal Information, and allow for penalties for violations and, in some cases, a private right of action. These laws also impose transparency and other obligations with respect to Personal Information and provide individuals with similar rights with respect to their Personal Information. We have invested, and continue to invest, human and technology resources in our efforts to comply with such requirements that are time-intensive and costly. The application and interpretation of such requirements are constantly evolving and are subject to change, creating a complex compliance environment. In some cases, these requirements may be either unclear in their interpretation and application or they may have inconsistent or conflicting requirements with each other. If we underestimate the cost of compliance, we may have to divert resources and increase spending, which could adversely impact our financial results and any non-compliance could cause us to lose business, which would decrease our revenues. Further, there has been a substantial increase in legislative activity and regulatory focus on data privacy and security in the United States and elsewhere, including in relation to cybersecurity incidents. In addition, some such requirements place restrictions on our ability to process Personal Information across our business or across country borders. Any failure or perceived failure by us to comply with such obligations may result in governmental investigations or enforcement actions, fines, litigation or legal proceedings (including class actions), or public statements against us by consumer advocacy groups or others and could cause our customers to lose trust in us, which could have an adverse effect on our reputation, results of operations, financial condition, and business. We could incur significant costs in investigating and defending such claims and, if found liable, pay significant damages or fines or be required to make changes to our business. These proceedings and any subsequent adverse outcomes may subject us to significant negative publicity and an erosion of trust. In the United States, we are subject to numerous federal, state and local data privacy and security laws and regulations governing the processing of information about individuals, including federal laws and state privacy laws, marketing and communications laws, laws regarding credit reports, data breach notification laws, and consumer protection laws, many of which carry significant potential for active enforcement and penalties. For example, the Federal Trade Commission and state regulators enforce a variety of data privacy issues, such as promises made in privacy policies or failures to appropriately protect information about individuals, as unfair or deceptive acts or practices in or affecting commerce in violation of the Federal Trade Commission Act or similar state laws. We are also subject to a patchwork of overlapping but different state privacy laws.

Our technologies could infringe the IP rights of others, causing costly litigation and the loss of significant rights.

Significant litigation regarding IP rights exists in the semiconductor industry. It is possible that a third party may claim that our technologies infringe their IP rights or misappropriate their trade secrets, which has happened in the past. Any claim, even if without merit, could be time consuming to defend, result in costly litigation, require us to enter into royalty or licensing agreements, which may not be available to us on acceptable terms, or at all, subject us to damages or injunctions restricting our sale of products, invalidate a patent or family of patents, require us to refund license fees to our customers or to forgo future payments or require us to redesign certain of our products, any one of which could adversely affect our sales opportunities, expenses, and revenues.

Competition in the market for data services and analytics and related systems and services may intensify in the future, which could impede our ability to grow or execute our strategy.

Our industry is marked by rapid technological developments and innovations (such as the use of AI and ML) and evolving industry standards. If we are unable to innovate quickly enough to keep pace with our competitors in incorporating such technological developments in our product offerings, our business could be harmed. See the discussion in “Competition” in Part 1, Item 1. “Business” section for more information about our current competitors. There may be other competitors of which we are not aware, and we may compete with the products or offerings of our existing competitor companies or additional companies if we expand our offerings through acquisitions or development. The demand for solutions that address the need for better integration between the silicon design and manufacturing processes and the need for insight into performance of those manufacturing processes may encourage new direct competitors to enter our market. Increased competition could lead to increased pricing pressure, negatively impacting our revenues, or a decreased ability to grow or execute our strategy. Also, our current and potential customers may choose to develop their own solutions internally or through another source, particularly if we are slow in deploying our solutions or improving them to meet market needs. These and other competitors may be able to operate with a lower cost structure than our engineering organization, which would give any such competitor’s products a competitive advantage over our solutions.

Use of generative AI and other advanced AI Technologies for software development may subject us to claims of misappropriation of others’ IP, bugs/errors, and ambiguous ownership of created content.

Uncertainty around new and emerging AI technologies such as generative AI technology content creation may require additional investment to protect our proprietary datasets, ML models, and systems to test for accuracy, bias and other variables, which may be costly and could impact our profit margin if we decide to expand generative AI into our product offerings. Acquiring licenses to programs to check programs written with the help of AI technologies, including determining whether such programs are secure and reliable, may also increase the cost profile of our offerings. Additionally, we could be liable for any inaccuracies or errors in software that we release that causes downtime or other damage to our customers’ facilities or production lines, which could greatly increase our expenses and decrease our earnings.

Use of open-source software (“OSS”) together with our products exposes us to potential legal liability and could negatively affect our ability to protect our intellectual property, and if support and updates for the OSS that we currently use in providing our products and services is not available to us, our financial results could be negatively impacted.

We use open-source software (“OSS”) in delivering products and services to our customers and in some cases are not able to obtain support or updates for some programs. Change of terms for support for OSS, or lack of support or updates for such OSS, could significantly increase our costs to deliver our products and services or cause a temporary or long-term disruption in our ability to use such OSS in our products and services or make it harder or impossible to mitigate vulnerabilities or risks associated with such software. This could negatively impact customers’ perception of our security or quality, cause us to lose business, or adversely impact our financial results.

From time to time, companies that use OSS have faced claims challenging the use of OSS or compliance with open source license terms, and we could be subject to such lawsuits. The terms of many OSS licenses to which we are subject have not been interpreted by U.S. or foreign courts, and there is a risk that open source licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our provision of our products and services. Litigation could be costly for us to defend, harm our business, results of operations or financial condition or require us to devote additional research and development resources to change our platform.

In addition, if we were to combine our proprietary software with OSS in a certain manner, we could, under certain open source licenses, be required to release the source code of our proprietary software. If we inappropriately use OSS, we may be required to re-engineer parts of our platform, extract the OSS at issue or take other remedial actions. In addition to risks related to license requirements, use of certain OSS can lead to greater risks than use of third-party commercial software, as open source licensors generally do not provide warranties, indemnities or controls on the origin of software equivalent to those provided by third-party commercial software providers. Any of the foregoing could adversely impact the value or enforceability of our intellectual property, and materially adversely affect our business, results of operations, and financial condition.

Risks Related to Our Operations

We face operational and financial risks associated with international customers and operations that could negatively impact our revenues.

We have customers globally and our standard operations include development, distribution processes, software download sites, and professional service centers and processes in various geographies around the world, including employees and contractors located in Shanghai, China and Ramallah, Palestine, Israel, and Taiwan. Any of the following could disrupt or limit our business opportunities, the work our international employees and contractors perform, negatively affect the range of services we are able to provide from anywhere, or increase our cost for such services:

●

changing circumstances in China regarding investments in the semiconductor industry by both private and public entities within China, which if the level of investments is substantially reduced could limit our future growth potential;

●

limits on access (i) by some of our key engineers and other personnel that are foreign nationals to certain technical information under U.S. export laws or by certain of our customers, or (ii) by such individuals to the United States and other countries in which our customers or our offices may be located;

●

difficulties recruiting, training, and retaining qualified technical and managerial employees in non-U.S. offices, and actions taken by our local dealers and partners, for which we may be liable and incur penalties, legal expenses, or have to pay damages, which would negatively impact our results of operations;

Table of Contents

●

greater difficulty in collecting accounts receivable from non-U.S. customers, resulting in longer collection periods, credit losses, and increased costs to collect;

●

inconsistencies among, and unexpected changes in, non-U.S. laws and regulatory environments, including, among others, those related to human resources, personal data, tax, protection of IP, corporate governance, and U.S laws and regulations related to anti-corruption, imports and exports, and trade and export controls, which could result in (i) substantial expense to us as we attempt to comply and resolve inconsistencies, (ii) liability for inadvertent or intentional breach, for example through fraudulent or negligent behavior of individual employees, and (iii) a requirement to make significant changes in our business operations or forego international business opportunities for a period of time or altogether, any of which could adversely affect our revenues or our overall business;

●

currency risk (i) due to certain of our payables and our international offices’ payables denominated in foreign currencies, including the Euro, Yen, and RMB, while predominantly all of our revenues is denominated in U.S. dollars, or (ii) in the event a larger portion of our revenues becomes denominated in foreign currencies, in either case, which could increase the cost in U.S. dollars to us or decrease the expected amount of revenues in U.S. dollars by the time of payment; or,

●

economic or political actions, policies, or instability, and the resulting restrictions and disruption to economic activity and business operations in such areas, which could potentially (i) interrupt our customers’ ability in such locations to make use of our products or services, or for our employees or contractors to provide services, (ii) impact our customers’ desire to buy local, or (iii) limit our ability to supply products, services and technologies to affected entities and countries, any of which may negatively impact our financial results.

Measurement of our variable consideration sometimes ~~require~~requires data collection and customers’ use of estimates and are contingent upon customers’ consent and may be later offset if actual data differ from customers’ estimates, which can result in uncertainty and cause quarterly results to fluctuate.

We can only recognize volume- or average selling price- (“ASP”) based royalties once we have reached agreement with our customers on their level of yield performance improvements or ASP and quarterly agreements are sometimes based on estimates of volume results or ASP for each quarter. Measuring the amount of yield improvement is inherently complicated and dependent on our customers’ internal processes and on certain non-public information that may not be directly available to us. Thus, there may be uncertainty as to some components of measurement or calculation. Also, some variable consideration can be highly susceptible to delays in our customers’ measurement of key factors such as reporting volumes results and level of yield or ASP. Therefore, we may have to estimate revenue related to contingent variable fees or usage- or sales-based royalties prior to the receipt of performance reports, such as royalty acknowledgements, or other related information from customers. These estimates are subject to judgment to evaluate whether it is probable that a significant revenue reversal will not occur in future periods, which could result in our recognition of less ~~Integrated~~Volume-based ~~Yield Ramp~~ revenue than expected that may later be offset when actual results become available if such results differ from estimates.

Errors affecting our proprietary hardware and software systems located in customers’ or third-parties’ facilities could lead to liability for us, and any objection from such customers or third-parties or delay in providing us with physical or logical access to such systems may adversely impact our ability to timely perform our contract obligations or lead to confidentiality, integrity, availability, security, or privacy controls exceptions.

In connection with our data services offerings, we rely on installing, configuring, and operating proprietary configurations of hardware and/or software systems in facilities owned and operated by customers and third parties around the world. If the customer or third-party facility owner/operator does not allow us to install, access and maintain, or otherwise operate our systems as intended, we may fail to timely fulfill our contractual obligations to, or expectations of, our customers or such third-party facility owner/operator. Also, any intentional or unintentional disruption of the operation of these proprietary systems may lead to customer or third-party facility owner/operator dissatisfaction, which could cause us to lose such site as a connected site or lose future bookings, which would reduce revenue and negatively impact our earnings. Additionally, any potential or actual malicious cybersecurity incident or accidental misconfiguration resulting in a data security incident involving these proprietary systems may require complex diagnosis and mitigation because they are located at customers’ and third-parties’ facilities and this may lead to delays, errors, lack of system availability, loss of our customers’ data integrity, or further unauthorized disclosure of customer or third-party confidential or personal data. Further, if our system causes downtime or other disruption or loss to such customer or third-party facility, we could be liable for damages associated with such event, which could increase our expenses and distract management, and cause other customers or third-party facilities to not want to work with us.

resulting in a data security incident involving these proprietary systems may require complex diagnosis and mitigation because they are located at customers’ and third-parties’ facilities and this may lead to delays, errors, lack of system availability, loss of our customers’ data integrity, or further unauthorized disclosure of customer or third-party confidential or personal data. Further, if our system causes downtime or other disruption or loss to such customer or third-party facility, we could be liable for damages associated with such event, which could increase our expenses and distract management, and cause other customers or third-party facilities to not want to work with us.

Installing and maintaining such proprietary systems around the world requires that we manage the complexity of global operations of individual installations at a large number of different third parties in various countries. The cost and complexity of obtaining support, installing updated security patches, and addressing any other critical vulnerabilities in each individual physical system may lead to exceptions in controls of confidentiality, availability, integrity, security, and privacy, which could negatively impact the availability of our data services to customers, damage our reputation, or lead to lower bookings or sales.

Delayed payment terms and unpaid accounts receivable will negatively impact our cash in the short term and if customers fail to pay unsecured accounts receivable for a significant time or at all, we may be required to write-off receivables or increase our expense or allowance for credit losses.

From time to time, we give customers delayed payment terms in connection with reaching final agreement on large contracts. When we do this, and if we continue to do it in the future on equal or larger total amounts, our cash is negatively impacted in the short-term. Since we generally do not require collateral or other security for accounts receivable, if customers fail to pay balances when due, in whole or part, we may incur additional expenses attempting to collect and our business relationship and future business with any such customer could suffer as a result of such collection efforts. We may also experience greater difficulty in collecting accounts receivable from non-U.S. customers, resulting in longer collection periods, credit losses, and increased costs to collect. If customers fail to pay at all, in whole or in part, we may have to write-off a portion or all of such receivables or to increase our expense or allowance for credit losses. Our accounts receivable balance, net of allowance for credit losses, was $7382.69 million and $4473.96 million as of December 31, ~~2024~~2025 and ~~2023~~2024, respectively. Unbilled accounts receivable, included in accounts receivable, totaled $2344.0 8 million and $1623.40 million as of December 31, ~~2024~~2025 and ~~2023~~2024, respectively. Unbilled accounts receivable that are not expected to be billed and collected during the succeeding twelve-month period are recorded in other non-current assets and totaled $98.07 million and $19.10 million as of December 31, ~~2024~~2025 and ~~2023~~2024, respectively. ~~Four~~Two customers accounted for 5764% of our gross accounts receivable as of December 31, ~~2024~~2025, and ~~two~~four customers accounted for 5057% of our gross accounts receivable as of December 31, ~~2023~~2024. The total allowance for credit losses was $0.9 million as of December 31, ~~2024~~2025 and ~~2023~~2024.

Tax Risks

Changes in tax laws, both within the United States and outside of the United States, could change our tax burden and adversely affect our business, financial condition and ~~financial~~results ~~condition~~of operations.

We conduct our business globally and, as a result, are subject to taxation in the United States and foreign countries. Our future tax rates could be affected by numerous factors, including changes in tax laws or the interpretation of such tax laws, insufficient taxable income to realize deferred tax assets, and changes in accounting policies. Our filings are subject to reviews or audit by the Internal Revenue Service and state, local and foreign taxing authorities. We cannot be sure that any final determination in an audit would not be materially different than the treatment reflected in our historical income tax provisions and accruals. If additional taxes are assessed as a result of an audit, there could be a significant negative effect on our income tax provision and our operating results in the period or periods for which that determination is made. Any changes in our geographical earnings mix in various tax jurisdictions, including those resulting from transfer pricing adjustments, could materially increase our effective tax rate.

We could lose the benefit of all or part of our deferred tax asset position, including the utilization of net operating loss and tax credit carryforwards, if we do not earn future taxable income in the applicable jurisdiction.

Realization of our deferred tax assets is dependent primarily upon future taxable income in the applicable jurisdiction. We previously recorded a full valuation allowance against all of our U.S. federal and state deferred tax assets due to the uncertainty surrounding the future realization of these deferred tax assets. Therefore, no benefit has been recognized for the net operating loss carryforwards, tax credit carryforwards, and other deferred tax assets. A portion of our net operating loss and tax credits could expire unused and be unavailable to reduce future income tax liabilities. We intend to continue maintaining a full valuation allowance on these deferred tax assets until there is sufficient evidence to support the reversal of all or some portion of these allowances. We evaluate our deferred tax assets for realizability each reporting period. If we delay or never release such valuation allowance, the corresponding benefit would be delayed or lost.

We intend to continue maintaining a full valuation allowance on these deferred tax assets until there is sufficient evidence to support the reversal of all or some portion of these allowances. We evaluate our deferred tax assets for realizability each reporting period. If we delay or never release such valuation allowance , the corresponding benefit would be delayed or lost.

Risks Related to Our Strategic Transactions

If we do not realize the benefits of our strategic relationships after we have ~~devote~~devoted significant time and resources to developing them, it could have an adverse effect on our business and results of operations.

We have in the past devoted, and plan in the future to devote, time and resources to identifying, developing, and promoting strategic relationships with other suppliers to provide combined, integrated, or interoperable solutions to the semiconductor, electronics, and automotive industries. The full extent of the future impact of these strategic relationships on our financial condition and results of operations is currently unknown and the failure to reap the anticipated benefits of these companies’ financial resources, technology, customer relationships, and global footprint and/or to successfully develop combined, integrated, or interoperable solutions with such companies could have an adverse effect on our business and results of operations.

Our acquisitions create special risks and challenges that could adversely affect our financial results.

Our success depends on our ability to continually enhance and broaden our product offerings in response to changing technologies, customer demands, and competitive pressures. To this end, we have, from time to time, engaged in the process of identifying, analyzing, and negotiating possible acquisition transactions, and, from time to time, acquiring one or more businesses, and we expect to continue to do so in the future. We may choose to acquire new and complementary businesses, products, technologies and/or services instead of developing them ourselves. For example, we acquired SecureWise LLC (“SecureWise”) in March 2025 for a gross purchase price of approximately $130 million. We may, however, face competition for acquisition targets from larger or more established companies with greater financial resources, making it more difficult or more expensive for us to complete acquisitions. We may not be successful in ~~completing~~consummating ~~and closing announced acquisitions, such as our planned acquisition of SecureWise LLC announced in February 2025, or in entering into~~ future acquisitions on favorable terms, and we may not realize the benefits that we anticipate from one or more acquisitions that we do close. Integrating any business, product, technology, or service into our current operations could be expensive and time-consuming and/or disrupt our ongoing business. Further, there are numerous risks associated with acquisitions and potential acquisitions, including, but not limited to, problems combining the purchased operations, technologies or products, unanticipated costs, liabilities, litigation, and diversion of management’s attention from our core businesses, adverse effects on existing business relationships with suppliers and customers, risks associated with entering markets in which we have no or limited prior experience, and where competitors in such markets have stronger market positions, initial dependence on unfamiliar supply chains or relatively small supply partners, failure of our due diligence processes to identify significant problems, liabilities or other challenges of an acquired company or technology, and the potential loss of key employees, customers, distributors, vendors, and other business partners of the companies we acquire.

We may not be able to successfully integrate businesses, products, technologies, or personnel that we might acquire and the transaction may not advance our business strategy. The integration of businesses that we may acquire is likely to be a complex, time-consuming, and expensive process and we may not realize the anticipated revenues or other benefits associated with our acquisitions. If we fail to successfully manage, operate, or integrate any acquired business or if we are unable to efficiently operate as a combined organization, including through the use of common information and communication systems, operating procedures, financial controls, and human resources practices, we could be required to write-down investments and our business, financial condition, and results of operations may be adversely affected. We may also be unable to protect or enforce the IP rights of any target business that we acquire, or such target businesses may become subject to claims of IP infringement. Further, if we become subject to liabilities as a result of an acquisition, the liabilities we incur may be substantial and the amounts of such liabilities may not be covered by and/or may exceed any liability protections.

In connection with certain acquisitions, we have in the past and may in the future issue common stock, or assume equity awards, that dilute the ownership of our current stockholders, use a substantial portion of our cash resources, assume liabilities (both known and unknown), record goodwill and amortizable intangible assets that will be subject to impairment testing on a regular basis and potential periodic impairment charges, incur amortization expenses related to certain intangible assets, incur large and immediate write-offs and restructuring and other related expenses, or incur substantial amounts of debt, all of which could harm our financial condition and results of operations.

General Risk Factors

If we are not able to retain, attract, motivate, and strategically locate talented employees, including some key executives, our business may suffer.

Our success and competitiveness depend on our ability to retain, attract, motivate, and strategically locate in our offices around the globe, talented employees, including some of our key executives. Achieving this objective may be difficult due to many factors, including fluctuations in global economic and industry conditions, changes in our management or leadership, the hiring practices at our competitors or customers, cost reduction activities, and the effectiveness of our recruiting and compensation programs, including equity-based programs. The aging semiconductor workforce creates risks as our experienced employees retire and accelerates the loss of critical knowledge. At the same time, educational programs and the needed work experience may not produce the critical talent in time to meet the growing technical demands we require in a workforce. Further, we have had, and expect to continue to have, difficulty in obtaining visas permitting entry for some of our employees that are foreign nationals into the United States, and delays in obtaining visas permitting entry into other key countries, for several of our key personnel, which disrupts our ability to strategically locate our personnel that exist primarily in foreign locations. In the past the United States has and, in the future, the United States may again increase the level of scrutiny in granting H-1(b), L-1, and other business visas. Compliance with United States immigration and labor laws could require us to incur additional unexpected labor costs and expenses or could restrain our ability to retain skilled professionals. If we lose the services of certain of our key executives or a significant number of our engineers, it could disrupt our ability to implement our business strategy. If we do not successfully attract, retain, and motivate key employees, including key executives, we may be unable to realize our business objectives and our operating results may suffer.

Our operating results vary quarter to quarter, which could result in not meeting investors’ expectations and stock price volatility.

Our stock price has been and may continue to be subject to fluctuations, including as a result of varying operating results, changes in recommendations or earnings estimates by financial analysts, changes in investors’ or analysts’ valuation measures for our stock and other factors beyond our control including macroeconomic factors. Our stock price may be adversely impacted by announcements related to financial results or forecasts that fail to meet or are inconsistent with earlier projections or the expectations of our securities analysts or investors, announcements of new products or acquisitions of new technologies by us, our competitors or our customers, or announcements of acquisitions, major transactions, litigation developments or management changes. Furthermore, speculation in the press or investment community about our strategic position, financial condition, results of operations, business or security of our products, can cause changes in our stock price. Also, significant volatility in our stock price could be followed by a securities class action lawsuit, which could result in substantial costs and a diversion of our management’s attention and resources.

Our business is subject to evolving corporate governance and public disclosure regulations and expectations, which could require significant resources in attempts to comply or expose us to legal liability if we fail to comply.

We are subject to changing rules and regulations promulgated by a number of governmental and self-regulatory organizations, including the SEC, the Nasdaq Stock Market, and the Financial Accounting Standards Board (“FASB”), as well as evolving investor, customer, employee and other stakeholder expectations around corporate governance, executive compensation and environmental and social practices and related disclosures. These rules, regulations and expectations continue to evolve in scope and complexity, and many new requirements have been created in response to laws enacted by U.S. and non-U.S. governments, making compliance more difficult and uncertain. For example, in January 2025, President Trump signed an executive order directing federal agencies to take steps to target diversity, equity and inclusion practices in the private sector, including directing each agency to identify up to nine opportune civil compliance investigations of publicly traded corporations, among others. We may be subject to increased litigation and regulatory scrutiny regarding these practices. We expect that changing rules and laws related to corporate governance, environmental and social matters, as well as increased enforcement actions by various governmental and regulatory agencies, will continue to increase the cost of our compliance and internal risk management programs, which could adversely affect our business, results of operations and financial condition.

Table of Contents

Our business could be negatively affected as a result of actions of activist shareholders, and such activism could impact our stock price.

Publicly-traded companies have increasingly become subject to activist investor campaigns. Responding to actions of an activist investor may be a significant distraction for our management and staff and could require us to expend significant time and resources, including legal fees and potential proxy solicitation expenses. Any of these conditions could materially adversely affect our financial performance and stock price.

Item 1C. Cybersecurity

Cybersecurity Risk Management and Strategy

We recognize the importance of assessing, identifying, and managing material risks associated with cybersecurity threats, as such term is defined in Item 106(a) of Regulation S-K. These risks include, among other things, operational risks, intellectual property theft, fraud, extortion, harm to employees or customers, violation of privacy or security laws and other litigation and legal risk, and reputational risks. We have implemented several cybersecurity processes, technologies, and controls in an effort to assess, identify, and manage such material risks.

Our process for identifying and assessing material risks from cybersecurity threats operates alongside our broader overall risk assessment process, covering all company risks. As part of this process appropriate disclosure personnel will collaborate with subject matter specialists, at least annually and more frequently as necessary due to business changes or external changes, to gather insights for identifying and assessing material cybersecurity threat risks, their severity, and potential mitigations.

We also have a cybersecurity specific risk assessment process, which helps identify our cybersecurity threat risks. As part of this process, and our processes aimed at providing for the availability of critical data and systems, maintaining regulatory compliance, identifying and managing our risks from cybersecurity threats, and protecting against, detecting, and responding to cybersecurity incidents, as such term is defined in Item 106(a) of Regulation S-K, we undertake the below listed activities, among others:

● maintain a risk register and risk assessment process ~~based~~for onour ~~The~~Information ~~National~~Security ~~Institute of Standards~~ and ~~Technology~~Management System (“~~NIST~~ISMS”) ~~Cybersecurity~~based ~~Framework~~on ~~(however, this does not imply that we meet any particular technical standards, specifications, or requirements, only that we use~~ the ~~NIST~~ISO ~~Cybersecurity~~27001:2022 ~~Framework~~clauses ~~as a guide to help us identify, assess,~~ and ~~manage cybersecurity risks relevant to our business)~~controls;

●

We regularly exercise and update the plan after actual incident responses or simulated incident response scenarios.

We subscribe to several external independent monitoring services to score and assess our externally facing network and information services and we engage a third-party security firm at least annually to conduct external and web penetration testing exercises on our corporate network and our commercial SaaS service platform and other commercial products and services in scope of our ISMS.

Our processes also address cybersecurity threat risks associated with our use of third-party service providers, including those in our supply chain or who have access to our customer and employee data or to our systems. Third-party risks are included within our broader overall risk assessment and management process, as well as our cybersecurity-specific risk identification program, both of which are discussed above. In addition, cybersecurity considerations affect the selection and oversight of our third-party service providers during vendor onboarding and during periodic reviews. We perform diligence on third parties that have access to our systems, data or facilities that house such systems or data, and regularly monitor cybersecurity threat risks identified through such diligence. Additionally, we generally require those third parties that could introduce significant cybersecurity risk to us to agree by contract to manage their cybersecurity risks in specified ways, and to agree to be subject to cybersecurity audits or independent information security assessments or certifications. Additionally, we have processes designed to monitor public and federal government database and other sources for evidence of known and/or exploited vulnerabilities in third-party services including those provided as SaaS and we take action to remediate or establish compensating controls if those systems are determined to be critical to our cybersecurity. We also maintain disaster recovery plans in place for all mission critical parts of the business, although we do not have a business continuity plan developed to account for all continuity risks.

We describe whether and how risks from identified cybersecurity threats, including as a result of any previous cybersecurity incidents, are reasonably likely to materially affect us, including our business strategy, results of operations, or financial condition, under the headings “We, and our third-party service providers, are exposed to risks related to information technology infrastructure, information management and protection, cybersecurity threats, and cyber incident; if we or our third-party providers fail to protect confidential information and/or experience a cyber incident, there may be damage to our brand and reputation, material financial penalties, and legal liability.” and “Our business is subject to evolving corporate governance and public disclosure regulations and expectations, including with respect to environmental, social and governance matters that could expose us to numerous risks.” included as part of our risk factor disclosures at Item 1A of this Annual Report on Form 10-K.

For more than 6 years, we have not identified any known cybersecurity threats including as a result of any prior cybersecurity incidents, that have materially impacted us or our operations, business strategy results of operations, or financial condition, including the expenses we have incurred from cybersecurity incidents that were immaterial. This includes penalties and settlements, of which there were none. We face risks from cybersecurity threats that, if realized, are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition.

Cybersecurity Governance

Information technology and data security, particularly cybersecurity, is a top area of focus for our Board of Directors, who views our focus in these areas as essential for the success of our company and the broader technology industry in which we operate.

As described in the Audit Committee Charter of the Board of Directors, the Audit Committee is tasked with oversight of certain risk issues, including cybersecurity. The Audit Committee is comprised entirely of independent directors, two of whom have significant work experience related to information security issues or oversight. Management reports high severity security incidents to the Audit Committee after they are discovered. Additionally, management provides a summary four times per year of all security incidents to the Audit Committee. The full Board of Directors is also provided an annual assessment of our security program, our internal response preparedness, and assessments led by outside assessors and auditors.

Our Incident Response Policy is reviewed annually and documents the controls and procedures for timely and accurate reporting of material cybersecurity incidents to the relevant parties, including the Audit Committee when applicable. Our Incident Response Team leads the response to any reported cybersecurity event and comprises experts from Engineering, Information Technology, Legal, Cloud Operations, and Network Security.

The Vice President of Operations and Executive Vice President of Products and Solutions ~~are~~take steps to stay informed about and monitor the prevention, mitigation, detection, and remediation of cybersecurity incidents through their management of, and participation in, the cybersecurity risk management and strategy processes described above including the incident response.

Item 2. Properties

Our principal executive offices are located in Santa Clara, California, where we lease approximately 20,800 square feet of office space under a lease agreement that expires in August 2028. We also lease additional facilities and offices, including in Milpitas, California; Pittsburgh, Pennsylvania; Richardson, Texas; Salt Lake City, Utah; Deer Park, Illinois; Shanghai, China; Canada; France; Germany; Italy; Japan; South Korea; and Taiwan for local sales, product development and technical support.

We believe our existing and planned facilities and offices are adequate to meet our current needs and are being utilized consistently with our past practice. We consistently look for opportunities to minimize costs related to office space through improved efficiencies and intend to make changes to leased facilities in the future as appropriate to reflect changes in worldwide operations and headcount.

Overview

We offer products and services designed to empower organizations across the semiconductor and electronics ecosystems to connect, collect, manage, and analyze data about design, equipment, manufacturing, and test to improve the yield and quality of their products. We derive revenues from two ~~sources~~categories: ~~Analytics~~Platform and ~~Integrated~~Volume-based ~~Yield Ramp~~Revenue. Our offerings combine proprietary software, professional services using proven methodologies and third-party cloud-hosting platforms for SaaS, electrical measurement hardware tools, and physical IP for IC designs. We primarily monetize our offerings through license fees and contract fees for professional services and SaaS. In some cases, ~~especially~~we onalso ~~our~~receive ~~historical~~a ~~Integrated~~Volume-based ~~Yield~~fee ~~Ramp~~such ~~engagements,~~as weCimetrix ~~also~~runtime ~~receive~~licenses and secureWISE data usage, and a value-based variable fee or royalty, which we call Gainshare.

data protection are increasingly in demand for insights and efficiencies across the organizations of these companies.

~~There~~Worldwide ~~are~~economic ~~other~~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 orfinancial ~~business~~markets ~~trends~~and ~~that~~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 ~~affect~~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 ~~business~~development ~~opportunities~~timelines ~~generally~~and ascustomer ~~follows:~~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).

The ~~worldwide~~leading ~~economic~~foundry ~~performance~~continues isto ~~uneven~~dominate market share.

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 ~~some~~various ~~instances~~geographic markets. ~~With~~The ~~high~~uncertainty ~~inventories~~caused by these regulations and ~~soft~~the ~~demand~~potential for ~~some~~additional ~~product~~future ~~segments~~restrictions could negatively affect our future sales, ~~some~~including ~~semiconductor~~in ~~fab~~but ~~utilization~~not ~~rates~~limited ~~are~~to ~~also~~the ~~low~~Republic ~~and~~of ~~semiconductor~~China ~~capital~~(“P.R.C.”) ~~equipment~~market. ~~orders~~Some customers in the P.R.C. have ~~been~~expressed ~~impacted~~concern about the potential for ~~some~~supply ~~vendors~~chain ~~and~~disruption ~~market~~due ~~segments~~to the U.S. Asgovernment’s achanging ~~result,~~export ~~some~~controls ~~purchase~~impacting ~~cycles~~their purchase, ~~especially~~or ~~for~~in ~~enterprise~~some ~~software~~case ~~and~~restricting ~~capital~~their ~~equipment~~ability ~~and~~to ~~particularly~~purchase, ~~with~~certain ~~respect~~U.S. togoods. ~~larger~~Based ~~deals~~on our current assessments, ~~have~~we ~~lengthened~~expect inthe ~~recent~~near-term ~~years~~impact ~~and~~of ~~may~~these ~~continue~~evolving trade restrictions on our business to dobe solimited.

● Changing export controls and sanctions. The U.S. government continues to expand and intensify export controls and sanctions, with a major focus on the destinations of and/or entities in the People’s Republic of China (“P.R.C.”), Russian Federation, and Belarus. Some customers in the P.R.C., in particular, have expressed concerns to us that continued action by the U.S. government could potentially interrupt their ability to make use of our products or services, which has in some cases, and could in the future, negatively impact the demand for our products and services by these customers. Recent additions to regulations include expansion of special Foreign Direct Product Rules, which extend the reach of the EAR to certain foreign-made products produced with certain U.S. items in certain cases of designated end-users or end-uses, and to renewal licenses for certain lawfully delivered products that would have changed status under new regulations. Such regulatory additions could negatively affect sales. Additional proposed and complicated regulations, including for added restrictions on U.S. person activity, remain pending. U.S. government policy and regulation remain fluid and uncertain, and could in the future impact segments of our business. Other countries and jurisdictions with important roles in our industry are updating some of their export control regulations to further align with those of the U.S. government and, in some cases, to counter U.S. regulations. For example, the P.R.C. has imposed restrictions on imports of certain memory integrated circuits (“ICs”) offered by U.S. companies and has been developing its legal authorities to counter foreign sanctions. On November 27, 2024, the U.S. government renewed its caution that visitors to the P.R.C. are subject to arbitrary enforcement of local laws and wrongful detention, a risk that could deter or hinder certain business activities. Based on our current assessments, we expect the near-term impact of these expanded trade restrictions on our business to be limited, but revisions, clarifications, and proposals that are still in government development and open questions of interpretation leave much unknown.

● Presidential Initiatives. The new U.S. Presidential Administration has recently stated its intention to change U.S. trade policy, including potentially renegotiating or terminating existing trade agreements and leveraging tariffs. In February 2025, the U.S. imposed additional tariffs on imports from China and announced and subsequently paused implementation of tariffs on imports from Canada and Mexico. We do not import into the U.S. a significant volume of goods of P.R.C. origin. Trade conflict through exchange of tariffs and other retaliatory

Table of Contents

actions would likely ripple through worldwide supply chains, could increase prices and put downward pressure on economic activity, and could negatively affect our future sales in various geographic markets. We will continue to monitor for any further trade restrictions, other regulatory or policy changes by the U.S. or foreign governments and any actions in response. The uncertainty caused by these recent regulations and the potential for additional future restrictions could negatively affect our future sales, including in but not limited to the P.R.C. market.

● Investments in semiconductor manufacturing. In 2022, the U.S. Congress passed into law funding programs from the bipartisan CHIPS and Science Act of 2022 (the “CHIPS Act”), authorizing the Department of Commerce, Department of Defense, and Department of State to develop onshore domestic manufacturing of semiconductors considered critical to U.S. competitiveness and national security. We expect funds under these programs will continue to support spending by U.S. semiconductor companies, especially manufacturers. Changes in governmental spending priorities or approvals could continue to impact payments under some of these programs, which we will monitor for effects on our business. Recipients of funding under such programs, may be required to agree to separate restrictions on certain commercial activity in the P.R.C., where we currently commercially operate. If our customers engage us for projects funded by these programs, we will evaluate all restrictions, and their impact on our existing business, before entering into any contracts associated with these programs. Similarly, the National Defense Authorization Act for Fiscal Year 2024 requires the U.S. Department of Defense to develop acquisition regulations controlling contracting with certain types of companies that perform consulting services for certain types of P.R.C. entities.

● Geopolitical tensions/conflicts. Geopolitical tensions and conflicts in various locations around the world continue to increase, including on the issue of Taiwan in Asia, Ukraine and Russia, and armed conflicts in the Middle East. These current situations have created volatility in the global financial markets and may have further global economic consequences, including potential disruptions of the global supply chain and heightened volatility of commodity and raw material prices. This has increased fears of a global recession. We have contractors located in the West Bank and in Israel, who are providing software development and customer technical support services, and we have developed contingency plans to use alternative resources to continue serving customers, if needed. Any escalations 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).

Financial Highlights

The following are our financial highlights for the year ended December 31, ~~2024~~2025:

● Total revenues were $~~179~~219.50 million for the year ended December 31, 2025, an increase of $1339.6 million, or 822%, compared to ~~the~~prior year ~~ended December 31, 2023~~. ~~Analytics~~Platform revenue was $~~169~~181.30 million for the year ended December 31, 2025, an increase of $1723.29 million, or 1115%, compared to ~~the~~prior year ~~ended December 31, 2023~~. The increase in ~~Analytics~~Platform revenue was driven by higher revenue from ~~Exensio~~fixed ~~and~~fees ~~Cimetrix~~associated ~~software~~with ~~licenses~~CV systems and ~~DFI~~the addition of revenues related to secureWISE systems, partially offset by adecreases ~~decrease~~ in revenue from CVperpetual ~~systems.~~licenses ~~Integrated~~and ~~Yield~~DirectScan ~~Ramp~~systems.

Critical Accounting Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires us to make judgments, assumptions, and estimates that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Notes 1 and 2 of the Notes to Consolidated Financial Statements (Item 8 of Part II of this Annual Report on Form 10‑K) describe the significant accounting policies and methods used in the preparation of the Consolidated Financial Statements. We consider the accounting policies described below to be our critical accounting policies. These critical accounting policies are impacted significantly by judgments, assumptions, and estimates used in the preparation of the Consolidated Financial Statements and actual results could differ materially from the amounts reported based on these policies.

Revenue Recognition

WePlatform ~~derive revenue from two sources: Analytics and Integrated Yield Ramp.~~Revenue

~~Analytics~~Platform ~~Revenue~~revenue is derived from the following primary offerings: licenses for software (other than Cimetrix runtime licenses) and related software maintenance and technical support services; SaaS; engineering services; fixed fees associated with CV systems; and licenses and purchase contracts for DirectScan systems.

~~Analytics~~Revenue ~~revenue~~from licenses for software, other than Cimetrix runtime licenses, is ~~derived~~recognized depending on whether the license is perpetual or time-based. Perpetual (one-time charge) license software is recognized at the time of the inception of the arrangement when control transfers to the customers as the software license is considered as a separate performance obligation from the ~~following~~services ~~primary~~offered ~~offerings:~~by ~~licenses~~us. Revenue from time-based-licensed software is allocated to each performance obligation and ~~services~~is ~~for~~recognized ~~standalone~~either ~~Software (which~~at ~~consists~~a ~~primarily~~point ofin ~~Exensio~~time or over time as follows. The license component is recognized at the time when control transfers to customers. Revenue from related software maintenance and ~~Cimetrix~~technical ~~products)~~support services, ~~SaaS~~or ~~(which~~post-contract ~~consists~~support, ~~primarily~~is ofrecognized ~~Exensio~~over ~~products),~~the ~~and~~contract ~~DFI~~term ~~and~~on a straight-line basis because we generally CVprovide ~~systems~~ (~~including~~i) ~~Characterization~~support ~~services~~and (ii) ~~that~~certain dosoftware ~~not~~updates ~~include~~on ~~performance~~a ~~incentives~~when-and-if ~~based~~available onbasis over ~~customers’~~the ~~yield~~contract ~~achievement~~term.

Revenue from standalone software is recognized depending on whether the license is perpetual or time-based. Perpetual (one-time charge) license software is recognized at the time of the inception of the arrangement when control transfers to the customers, if the software license is distinct from the services offered by us. Revenue from post-contract support is recognized over the contract term on a straight-line basis, because we are providing (i) support and (ii) unspecified software updates on a when-and-if available basis over the contract term. Revenue from time-based-licensed software is allocated to each performance obligation and is recognized either at a point in time or over time as follows. The license component is recognized at the time when control transfers to customers, with the post-contract support component recognized ratably over the committed term of the contract. For contracts with any combination of licenses, support, and other services, distinct performance obligations are accounted for separately. For contracts with multiple performance obligations, we allocate the transaction price of the contract to each performance obligation on a relative basis using the standalone selling price (“SSP”) attributed to each performance obligation. 37

Revenue from SaaS arrangements, which allow for the use of a cloud-based software product or service over a contractually determined period of time without the customer having to take possession of the software, is accounted for as subscriptions and is recognized as revenue ratably, on a straight-line basis, over the subscription period beginning on the date the service is first made available to customers. For contracts with any combination of SaaS and related services, distinct performance obligations are accounted for separately. For contracts with multiple performance obligations, we allocate the transaction price of the contract to each performance obligation on a relative basis using the SSP attributed to each performance obligation.

Revenue from DFI systems and CV systems (including Characterization services) that do not include performance incentives based on customers’ yield achievement is recognized primarily as services are performed. Where there are distinct performance obligations, we allocate revenue to all deliverables based on their SSPs. For these contracts with multiple performance obligations, we allocate the transaction price of the contract to each performance obligation on a relative basis using the SSP attributed to each performance obligation. Where there are not discrete performance obligations, historically, revenue is primarily recognized as services are performed using a percentage of completion method based on costs or labor-hours inputs, whichever is the most appropriate measure of the progress towards completion of the contract. The estimation of percentage of completion method is complex and subject to many variables that require significant judgment.

Assets subject to operating leases remain in Property and equipment and continue to be depreciated.

~~Integrated~~Revenue ~~Yield~~from ~~Ramp~~ purchase contracts for DirectScan systems is recognized at a point in time when our performance obligations have been completed, and the customer has accepted the product. Revenue from licenses for hardware is recognized depending on whether we classify the contract as an operating or a sales-type lease. Where the customer controls the use of identified assets for a period of time defined in a contract, it will be classified as a sales-type lease if it meets certain criteria under FASB Accounting Standards Codification (“ASC”) Topic 842, Leases, otherwise, it will be classified as an operating lease. Operating lease revenue is recognized on a straight-line basis over the lease term. Sales-type lease revenue and corresponding lease receivables are recognized at lease commencement based on the present value of the future lease payments, and related interest income on lease receivable is recognized over the lease term and recorded under Platform revenue in the Consolidated Statements of Operations and Comprehensive Income (Loss). Payments under sales-type leases are discounted using the interest rate implicit in the lease. When our leases are embedded in contracts with customers that include non-lease performance obligations, we allocate consideration in the contract between lease and non-lease components based on their relative SSPs. Assets subject to operating leases are included in property and equipment and subject to depreciation. Assets subject to sales-type leases are derecognized from property and equipment, net at lease commencement and a net investment in the lease asset is recognized in prepaid expenses and other current assets and other non-current assets in the Consolidated Balance Sheets.

Integrated Yield Ramp revenue is derived from our fixed fee engagements that include performance incentives based on customers’ yield achievement (which consists primarily of Gainshare royalties) typically based on customers’ wafer shipments, pertaining to these fixedVolume-~~fee contracts, which royalties are variable.~~based Revenue

Significant Judgments

Judgments and estimates are required under ASC Topic 606, Revenue from Contracts with Customers, and its related amendments (collectively known as “ASC 606”). Due to the complexity of certain contracts, the actual revenue recognition treatment required under ASC 606 for our arrangements may be dependent on contract-specific terms and may vary in some instances.

For revenue under project-based contracts for fixed-price services, revenue is recognized as services are performed using a percentage-of-completion method based on costs or labor-hours input method, whichever is the most appropriate measure of the progress towards completion of the contract. Due to the nature of the work performed in these arrangements, the estimation of percentage of completion method is complex, subject to many variables and requires significant judgment. Key factors reviewed by us to estimate costs to complete each contract are future labor and product costs and expected productivity efficiencies. If circumstances arise that change the original estimates of revenues, costs, or extent of progress toward completion, revisions to the estimates are made. These revisions may result in increases or decreases in estimated revenues or costs, and such revisions are reflected in revenue on a cumulative catch-up basis in the period in which the circumstances that gave rise to the revision become known.

Table of Contents

Our contracts with customers often include promises to transfer products, software licenses and provide services, including professional services, technical support services, and rights to unspecified updates to a customer. Determining whether licenses and services are distinct performance obligations that should be accounted for separately, or not distinct and thus accounted for together, requires significant judgment. We rarely license software on a standalone basis, so we are required to estimate the range of SSPs for each performance obligation. In instances where the SSP is not directly observable because we do not license the software or sell the service separately, we determine the SSP using information that may include market conditions and other observable inputs.

We ~~are~~typically ~~required~~recognize ~~to record~~ Gainshare revenue in the same period in which the usage occurs. Because we generally do not receive the acknowledgment reports from its customers during a given quarter within the time frame necessary to adequately review the reports and include the actual amounts in quarterly results for such quarter, we accrue the related revenue based on estimates of customers underlying sales achievement. Our estimation process can be based on historical data, trends, seasonality, changes in the contract rate, knowledge of the changes in the industry and changes in the customer’s manufacturing environment learned through discussions with customers and sales personnel. As a result of accruing revenue for the quarter based on such estimates, adjustments will be required in the following quarter to true-up revenue to the actual amounts reported.

Income Taxes

We are required to assess whether it is “more likely than not” that we will realize our deferred tax assets (“DTAs”). If we believe that they are not likely to be fully realizable before the expiration dates applicable to such assets, then to the extent we believe that recovery is not likely, we must establish a valuation allowance. Based on all available evidence, both positive and negative, we determined a full valuation allowance was still appropriate for our U.S. federal and state net DTAs, ~~primarily driven by a cumulative loss incurred over the 12-quarter period ended~~ December 31, ~~2024, and the likelihood that we may not utilize tax attributes before they expire~~2025. The valuation allowance was approximately $6769.9 million and $6467.29 million as of December 31, ~~2024~~2025 and ~~2023~~2024, respectively. We will continue to evaluate the need for a valuation allowance and may change our conclusion in a future period based on changes in facts (e.g., ~~12-quarter cumulative profit,~~ significant new revenue, ~~etc.~~and other relevant factors). If we conclude that we are more likely than not to utilize some or all of our U.S. DTAs, we will release some or all of our valuation allowance and our income tax expense will decrease in the period in which we make such determination.

We evaluate our DTAs for realizability considering both positive and negative evidence, including our historical financial performance, projections of future taxable income, future reversals of existing taxable temporary differences, tax planning strategies and any carryback availability. In evaluating the need for a valuation allowance, we estimate future taxable income based on management approved business plans. This process involves significant management judgment about assumptions that are subject to change from period to period based on changes in tax laws or variances between future projected operating performance and actual results. Changes in the net DTAs, less offsetting valuation allowance, in a period are recorded through the income tax expense and could have a material impact on the Consolidated Statements of Operations and Comprehensive Income (Loss).

Our income tax calculations are based on the application of applicable U.S. federal, state, and/or foreign tax law. Our tax filings, however, are subject to audit by the respective tax authorities. Accordingly, we recognize tax liabilities based upon our estimate of whether, and the extent to which, additional taxes will be due when such estimates are more-likely-than-not to be sustained. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. To the extent the final tax liabilities are different than the amounts originally accrued, the increases or decreases are recorded as income tax expense or benefit in the Consolidated Statements of Operations and Comprehensive Income (Loss). As of December 31, ~~2024~~2025, no deferred taxes have been provided on undistributed earnings from our international subsidiaries. We intend to reinvest the earnings of our non-U.S. subsidiaries in those operations indefinitely. As such, we have not provided for any foreign withholding taxes on the earnings of foreign subsidiaries as of December 31, ~~2024~~2025. The earnings of our foreign subsidiaries are taxable in the U.S. in the year earned under the Global Intangible Low-Taxed Income rules implemented under 2017 Tax Cuts and Jobs Act.

~~Stock-Based Compensation~~ 39

Table of Contents

~~service period. As stock~~Stock-~~based~~Based compensation expense recognized is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.Compensation

We account for stock-based compensation using the fair value method, which requires us to measure stock-based compensation based on the grant-date fair value of the awards and recognize the compensation expense over the requisite service period. As stock-based compensation expense recognized is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

The fair value of our restricted stock units is equal to the market value of our common stock on the date of the grant. These awards are subject to time-based vesting which generally occurs over a period of four years.

The fair value of our stock options and purchase rights granted under employee stock purchase plan is estimated using the Black-Scholes-Merton option-pricing model, which incorporates various assumptions including volatility, expected life and interest rates. The expected volatility is based on the historical volatility of our common stock over the most recent period commensurate with the estimated expected life of our stock options and purchase rights granted under employee stock purchase plan. The expected life is based on historical experience and on the terms and conditions of the stock options granted and purchase rights granted under employee stock purchase plan. The interest rate assumption is based upon observed Treasury yield curve rates appropriate for the expected life of our stock options and purchase rights granted under employee stock purchase plan.

Business Combinations

We allocate the fair value of purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired based on their estimated fair values at the date of the business combination. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Such valuations require us to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, estimated replacement costs and future expected cash flows from acquired customers, acquired technology, acquired patents, and trade names from a market participant perspective, useful lives and discount rates. The estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Allocation of purchase consideration to identifiable assets and liabilities affects our amortization expense, as acquired finite-lived intangible assets are amortized over their useful life, whereas any indefinite lived intangible assets, including in-process research and development and goodwill, are not amortized but tested annually for impairment. During the measurement period, which is not to exceed one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings in the Consolidated Statements of Operations and Comprehensive Income (Loss).

Valuation of Long-lived Assets including Goodwill and Intangible Assets

We record goodwill when the purchase consideration of an acquisition exceeds the fair value of the net tangible and identified intangible assets as of the date of acquisition. We have one operating segment and one operating unit. We perform a qualitative analysis when testing a reporting unit’s goodwill for impairment. We perform an annual impairment assessment of goodwill during the fourth quarter of each calendar year or more frequently, if required to determine if any events or circumstances exist, such as an adverse change in business climate or a decline in the overall industry demand, that would indicate that it would more likely than not reduce the fair value of a reporting unit below its carrying amount, including goodwill. If events or circumstances do not indicate that the fair value of a reporting unit is below its carrying amount, then goodwill is not considered to be impaired and no further testing is required. If the carrying amount exceeds its fair value, an impairment loss would be recognized equal to the amount of excess, limited to the amount of total goodwill. There was no impairment of goodwill for the years ended December 31, ~~2024~~2025, ~~2023~~2024 and ~~2022~~2023.

Our long-lived assets, excluding goodwill, consist of property, equipment, intangible assets and unguaranteed residual assets under net investments in sales-type leases. We periodically review our long-lived assets for impairment. For assets to be held and used, we initiate our review whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset group may not be recoverable. Recoverability of an asset group is measured by comparison of its carrying amount to the expected future undiscounted cash flows that the asset group is expected to generate. If it is determined that an asset group is not recoverable, an impairment loss is recorded in the amount by which the carrying amount of the asset group exceeds its fair value. There was no impairment of long-lived assets for the years ended ~~December~~ December 31, ~~2024~~2025, ~~2023~~2024 and ~~2022~~2023.

Leases

We have operating leases for our administrative and sales offices, research and development laboratory and clean room. We recognize our long-term operating lease rights and commitments as operating lease right-of-use assets, ~~operating lease liabilities~~ and operating lease liabilities, ~~non-current,~~ respectively, on our Consolidated Balance Sheets. We elected to not separate lease and non-lease components for all of our leases.

We determine if an arrangement is, or contains, a lease at inception. Operating lease right-of-use assets, and operating lease liabilities are initially recorded based on the present value of lease payments over the lease term. Lease terms include the minimum unconditional term of the lease, and may include options to extend or terminate the lease when it is reasonably certain at the commencement date that such options will be exercised. The decision to include these options involves consideration of our overall future business plans and other relevant business economic factors that may affect our business. Since the determination of the lease term requires an application of judgment, lease terms that differ in reality from our initial judgment may potentially have a material impact on our Consolidated Balance Sheets. In addition, our leases do not provide an implicit rate. In determining the present value of our expected lease payments, the discount rate is calculated using our incremental borrowing rate determined based on the information available, which requires additional judgment.

~~Revenues~~As our business evolved to include revenue from a broader portfolio of products and services, ~~Costs~~as a result of ~~Revenues~~organic and inorganic expansion, beginning with this Annual Report on Form 10-K, we updated our presentation of revenue categories. Previously, we presented revenue in two categories: Analytics and ~~Gross~~Integrated ~~Margin~~Yield Ramp. Analytics revenue was derived from the following offerings: licenses and services for on-premise software, SaaS, licenses and purchase contracts for DirectScan systems, and Characterization Vehicle systems that did not include performance incentives based on customers’ yield achievement. Integrated Yield Ramp revenue was comprised of all fees from our contracts that included any performance incentives based on customers’ yield achievement. We now present revenues in the following categories: Platform and Volume-based. Platform revenue is derived from the following offerings: licenses for software (other than Cimetrix runtime licenses) and related software maintenance and technical support services; SaaS; engineering services; fixed fees associated with CV systems; and licenses and purchase contracts for DirectScan systems. Volume-based revenue is derived from Cimetrix runtime licenses, secureWISE data, and Gainshare. See Note 2, “Revenue from Contracts with Customers” of the Notes to Consolidated Financial Statements included under Part II, Item 8 of this Annual Report on Form 10‑K.

Analytics revenue was $169.3 million for the year ended December 31, 2024, an increase of $17.2 million, or 11%, compared to the year ended December 31, 2023. The increase in Analytics revenue was driven by increases in revenue from Exensio and Cimetrix software licenses and DFI systems, partially offset by a decrease in revenue from CV systems.

~~Integrated Yield Ramp revenue was $10.2 million for the year ended December 31~~Revenues, ~~2024,~~Costs ~~a decrease~~ of ~~$3.5 million~~Revenues, ~~or 26%, compared to the year ended December 31, 2023, primarily due to a decrease in hours worked on fixed fee engagements~~ and aGross ~~decrease in customer wafer shipments at non-leading-edge nodes.~~Margin

Our Integrated Yield Ramp revenue may continue to fluctuate from period to period primarily due to fluctuations in customers’ wafer production under 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.

Platform Revenue

Platform revenue was $181.0 million for the year ended December 31, 2025, an increase of $23.9 million, or 15%, compared to the year ended December 31, 2024. The increase in Platform revenue was primarily driven by increases in revenue from fixed fees associated with CV systems and the addition of revenues related to SecureWISE systems, partially offset by decreases in revenue from perpetual license and DirectScan systems.

Volume-based Revenue

Volume-based revenue was $38.0 million for the year ended December 31, 2025, an increase of $15.7 million, or 70%, compared to the year ended December 31, 2024. The increase in Volume-based revenue was due to increases in revenue from Gainshare, secureWISE data usage, and Cimetrix runtime license.

Our revenues may also fluctuate in the future due to other factors, including the semiconductor industry’s continued acceptance of our products, services and solutions, the timing of purchases by existing and new customers, cancellations by existing customers, our ability to attract new customers and penetrate new markets, supply chain challenges and further penetration of our current customer base. Fluctuations in future results may also occur if any of our significant customers renegotiate pre-existing contractual commitments, including due to adverse changes in their own business.

Costs of Revenues

Costs of revenues consist primarily of costs incurred to provide and support our services, costs recognized in connection with licensing our software, IT and facilities-related costs and amortization of acquired technology. Service costs include material costs, hardware costs (including cost of leased assets under sales-type leases), personnel-related costs (including compensation, employee benefits, bonus and stock-based compensation expense), subcontractor costs, overhead costs, travel expenses, and allocated facilities-related costs. Software license costs consist of costs associated with third-party cloud-delivery related expenses and licensing third-party software used by us in providing services to our customers in solution engagements or sold in conjunction with our software products.

The increase in costs of revenues of $26.45 million for the year ended December 31, ~~2024~~2025, compared to the year ended December 31, ~~2023~~2024, was primarily due to (i) a $14.60 million increase in ~~hardware~~personnel-related costs due to increased headcount, worldwide salary increases, increase in employee benefit costs, higher bonus and stock-based compensation expenses, (ii) a $02.91 million increase in subcontractor fees, (iii) a $01.96 million increase in software license and maintenance costs, (iv) a $1.3 million increase in amortization of acquired technology, (v) a $1.0 million increase in third-party cloud-delivery costs, ~~and~~ (ivvi) a $0.2 7 million increase in facilities ~~personnel~~and IT-related costs, ~~mostly~~including ~~due~~depreciation toand ~~higher~~amortization ~~stock-based~~expense, ~~compensation~~and ~~expenses~~(vii) a $0.2 million increase in travel expense. These increases were partially offset by a $14.24 million decrease in ~~facilities~~ ~~and IT~~hardware-related costs ~~including depreciation and amortization expense~~.

Research and development expenses consist primarily of personnel-related costs (including compensation, employee benefits, bonus and stock-based compensation expense), outside development services, travel expenses, third-party cloud-services related costs, IT and facilities cost allocations to support product development activities.

43Research and development expenses increased by $10.7 million for the year ended December 31, 2025, compared to the year ended December 31, 2024, primarily due to (i) a $5.4 million increase in personnel-related costs due to increased headcount, worldwide salary increases, increased employee benefit costs, higher bonus, and stock-based compensation expense, (ii) a $2.4 million increase in subcontractor expenses primarily related to secureWISE systems and Exensio software, (iii) a $ 2.0 million increase in facilities and IT-related costs, including depreciation and amortization expense, and (iv) a $0.7 million increase in travel expenses.

Table of Contents

Research and development expenses increased $2.8 million for the year ended December 31, 2024, compared to the year ended December 31, 2023, primarily due to (i) a $1.6 million increase in personnel-related costs mostly due to higher stock-based compensation expenses, higher other compensation expenses (including employee benefit costs) resulting from increased headcount and worldwide salary increases, (ii) a $0.7 million increase in subcontractor expenses primarily related to Cimetrix and Exensio software, and (iii) a $0.4 million increase in third-party cloud-services related costs.

We anticipate our expenses in research and development will fluctuate in absolute dollars from period to period as a result of the size and the timing of product development projects.

Any significant change in our future effective tax rates could adversely impact our consolidated financial position, results of operations, and cash flows. Our future tax rates may be adversely affected by a number of factors including increase in expenses not deductible for tax purposes, new or changing tax legislation in the United States and in foreign countries where we are subject to tax jurisdictions, the geographic composition of our pre-tax income, the amount of our pre-tax income as business activities fluctuate, our ability to use tax attributes such as research and development tax credits and net operation losses, the tax effects of employee stock activity, audit examinations with adverse outcomes, changes in general accepted accounting principles and the effectiveness of our tax planning strategies.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. 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. 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 this election, we recognized a favorable cash tax benefit of approximately $1.3 million and reduction of our effective tax rate by approximately 40% in 2025. The OBBBA includes multiple effective dates, with certain provisions effective in 2025 and others phased in through 2027. We will continue to assess the impact on the effective tax rate for future periods.

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 2025 consolidated financial statements because we do not currently meet the 750 million Euro sales threshold.

Negative covenants include, among others, restrictions on the incurrence of debt, the incurrence of liens, the making of investments and distributions, dividends, and stock buy-backs. In addition, the Credit Agreement requires that we maintain a consolidated total net leverage ratio of not greater than 3.00 to 1.00, and a consolidated fixed charge coverage ratio of not less than 1.25 to 1.00. As of December 31, 2025, we were in compliance with the covenants contained in the Credit Agreement.

The Credit Agreement contains customary events of default. Upon the occurrence and during the continuance of an event of default, the Agent may declare the outstanding advances and all other obligations under the Credit Agreement immediately due and payable.

The obligations under the Credit Agreement are guaranteed by all present and future material domestic subsidiaries of the Company (collectively with the Company referred to herein as the “Credit Parties”), subject to customary exceptions, and are secured by the equity interests of the Credit Parties (other than the Company) and substantially all of the personal property owned by the Credit Parties, including 65% of the equity interests of certain foreign subsidiaries owned by the Credit Parties.

The Company used the amounts borrowed under the Credit Facilities to finance, in part, the purchase price paid for the acquisition of SecureWise.

Repurchase of Company’s Common Stock

On April 11, 2022, our Board of Directors adopted a stock repurchase program (the “2022 Program”) to repurchase up to $35.0 million of our common stock both on the open market and in privately negotiated transactions, including through Rule 10b5-1 plans, from time to time, over the next two years from the adoption date.

Net Cash Provided by Operating Activities

Cash flows provided by operating activities during the years ended December 31, 2024 and 2023, consisted of net income, 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 and net change in operating assets and liabilities.

We expect cash from our operating activities to fluctuate due to the level of our business activities, the timing of billings and payments terms as set forth in our agreements with our customers, the timing of cash disbursements to our vendors and settlement of other liabilities. The decrease in cash flows provided by operating activities during the year ended December 31, 2024, as compared to the year ended December 31, 2023, was driven primarily by (i) an increase in accounts receivable primarily due to an increase in total revenues and the impact of the timing of contractual invoicing activities resulting to lower collections from customers, and (ii) increases in payments of personnel-related costs and vendor invoices, partially offset by an increase in net income between comparable periods. Net income was $4.1 million for the year ended December 31, 2024, compared to net income of $3.1 million for the year ended December 31, 2023.

Subsequent to December 31, 2024, we collected more than half of the $51.6 million billed accounts receivable as of that date.

Net Cash Provided by (Used in) Investing Activities

Net cash used in investing activities was $5.9 million for the year ended December 31, 2024, compared to net cash used in investing activities of $29.0 million for the year ended December 31, 2023.

For the year ended December 31, 2024, cash used in investing activities primarily related to purchases of short-term investments of $54.3 million, purchases of and prepayments for property and equipment of $17.8 million primarily related to our DFI system, and the purchase of a convertible promissory note of $2.0 million, partially offset by proceeds from maturities and sales of short-term investments of $68.1 million.

For the year ended December 31, 2023, cash used in investing activities primarily related to purchases of short-term investments of $59.6 million, purchases of and prepayments for property and equipment of $11.3 million primarily related to our DFI and CV systems, and the payment for a business acquisition, net of cash acquired, of $1.8 million, partially offset by proceeds from maturities and sales of short-term investments of $43.8 million.

Net Cash Used in Financing Activities

Net cash used in financing activities was $11.2 million for the year ended December 31, 2024, compared to net cash used in financing activities of $5.9 million for the year ended December 31, 2023.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

The following discusses our exposure to market risk related to changes in interest rates and foreign currency exchange rates. We do not currently own any equity investments, nor do we expect to own any in the foreseeable future. This discussion contains forward-looking statements that are subject to risks and uncertainties. Actual results could vary materially as a result of a number of factors.

Interest Rate Risk. ~~As of December~~ ~~31,~~Our ~~2024,~~exposure we had cash and cash equivalents and short-term investments of $114.9 million. Cash and cash equivalents consisted of cash and highly liquid money market instruments. Short-term investments consisted of U.S. Government securities. We would not expect our operating results or cash flows to ~~be affected to any significant degree by the effect of a sudden change in~~ market ~~interest~~risk onfor ~~our~~changes ~~portfolio. A hypothetical increase~~ in ~~market~~ interest rates ofrelates ~~100 basis~~primarily ~~points~~to ~~from~~our ~~the~~investment ~~market~~portfolio ~~rates~~and ~~in effect at December 31, 2024, would cause the fair value of short~~long-term ~~investments~~debt toas ~~decrease~~described ~~by an immaterial amount which would not have significantly impacted our financial position or results of operations~~below.

As of December 31, ~~2024~~2025, we had cash and ~~periodically~~cash ~~throughout~~equivalents ~~the~~of $42.2 ~~year,~~million. weCash ~~have~~and ~~maintained~~cash equivalents consisted of cash ~~balances~~and inhighly ~~various~~liquid ~~operating~~money ~~accounts~~market ininstruments. ~~excess~~We ofwould ~~federally~~not ~~insured~~expect ~~limits.~~our Weoperating ~~limit~~results ~~the~~or ~~amount~~cash offlows ~~credit~~to ~~exposure~~be affected to any ~~financial~~significant ~~institution~~degree by ~~evaluating~~the effect of a sudden change in market interest on our portfolio.

Foreign Currency and Exchange Risk. Certain of our cash balances, receivables and payables for our international offices are denominated in the local currency, including the Euro, Yen, Chinese Yuan, New Taiwan Dollar and Canadian Dollar. Therefore, some of our activities including a portion of our revenues and operating expenditures are subject to foreign currency risks. We also have intercompany transactions with and between certain of our subsidiaries of differing functional currencies, resulting in foreign transaction gains or losses based on our period-end exchange rates. Due to potential volatility of currency exchange rates, we cannot predict the effect of exchange fluctuations on our business. During the years ended December 31, 2024, 2023 and 2022, we did not enter into any foreign currency derivative financial instruments.

Table of Contents

As of December 31, 2025, and periodically throughout the year, we have maintained cash balances in various operating accounts in excess of federally insured limits. We limit the amount of credit exposure to any financial institution by evaluating the creditworthiness of the financial institutions with which we invest and investing through more than one financial institution.

We are exposed to interest rate risk through our variable rate debt. As of December 31, 2025, we had $68.1 million of debt that is subject to variable interest rates that are based on the daily simple secured overnight financing rate (“SOFR”) or an alternate base rate. Refer to Note 7, “Debt” of the Notes to Consolidated Financial Statements (Item 8 of Part II of this Annual Report on Form 10‑K) for details relating to the debt. If the rates were to increase by 100 basis points from the rates in effect as of December 31, 2025, our interest expense on the variable rate debt would increase by an average of $0.4 million annually. There are inherent limitations in the sensitivity analysis presented, primarily due to the assumptions that interest rate changes would be instantaneous, while SOFR changes regularly. We do not currently hedge our interest rate risks but may determine to do so in the future. We will continue to monitor our exposure to interest rate risk.

Foreign Currency and Exchange Risk. Certain of our cash balances, receivables and payables for our international offices are denominated in the local currency, including the Euro, Yen, Chinese Yuan, New Taiwan Dollar and Canadian Dollar. Therefore, some of our activities including a portion of our revenues and operating expenditures are subject to foreign currency risks. We also have intercompany transactions with and between certain of our subsidiaries of differing functional currencies, resulting in foreign transaction gains or losses based on our period-end exchange rates. Due to potential volatility of currency exchange rates, we cannot predict the effect of exchange fluctuations on our business. During the years ended December 31, 2025, 2024 and 2023, we have not entered into any foreign currency exchange contracts and currently do not expect to enter into foreign currency exchange contracts for trading or speculative purposes.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

PDF Solutions, Inc.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of PDF Solutions, Inc. (a Delaware corporation) and its subsidiaries (the “Company”) as of December 31, ~~2024~~2025 and ~~2023~~2024, and the related consolidated statements of operations and comprehensive income (loss), stockholders’ equity, and cash flows for each of the three years in the period ended December 31, ~~2024~~2025, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, ~~2024~~2025 and ~~2023~~2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, ~~2024~~2025, in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, ~~2024~~2025, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 2724, ~~2025,~~2026 expressed an unqualified opinion.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) ~~relate~~relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit ~~matters~~matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate ~~opinions~~opinion on the critical audit matter or on the ~~accounts~~account or ~~disclosures~~disclosure to which ~~they~~it ~~relate~~relates.

Revenue Recognition

As described in Note 2 to the consolidated financial statements, the Company derives revenue from ~~Analytics~~Platform and ~~Integrated~~Volume-based ~~Yield Ramp~~revenue. Contracts with customers can include various combinations of licenses, subscriptions, products and services, some of which are distinct and are accounted for as separate performance obligations. Significant judgment is exercised by the Company in determining revenue recognition for customer agreements, including determining whether licenses, subscriptions, and services are distinct performance obligations, determining the standalone selling price (“SSP”) attributed to each performance obligation, establishing the pattern of delivery for each distinct performance obligation, and estimating variable consideration when determining the amount of revenue to recognize. In addition, for revenue under project-based contracts for fixed-price services, revenue is recognized as services are performed using a percentage-of-completion (“POC”) method based on costs or the labor-hours input method.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of internal controls relating to the revenue recognition process, including internal controls related to (1) the identification of distinct performance obligations and data used to establish SSP for licenses, subscriptions, products and services, (2) project estimates to completion for fixed fee arrangements accounted for under POC and (3) estimates of Gainshare royalty revenue accrual and subsequent true-ups. These procedures also included, among others, evaluating management’s significant accounting policies related to these customer agreements for reasonableness. In addition, for a sample of customer agreements, we obtained and read contract source documents, including master agreements and other documents that were part of the agreement, tested management’s identification of significant terms for completeness, including the identification of distinct performance obligations and variable consideration, assessed the terms in the customer agreements and evaluated the appropriateness of management’s application of their accounting policies, along with their use of estimates, in the determination of revenue recognition conclusions, and tested the mathematical accuracy of management’s calculations of revenue and the associated timing of revenue recognized in the consolidated financial statements. In addition, we evaluated the reasonableness of management’s estimates of SSP for projects and services that are not sold separately, where applicable, costs to complete for project-based contracts for fixed-price services and customers’ underlying achievements for royalty revenue.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of PDF Solutions, Inc. (a Delaware corporation) and its subsidiaries (the “Company”) as of December 31, ~~2024~~2025, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, ~~2024~~2025, based on criteria established in Internal Control—Integrated Framework (2013) issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated balance sheets as of December 31, ~~2024~~2025 and ~~2023~~2024 and the related consolidated statements of operations and comprehensive income (loss), stockholders’ equity, and cash flows for each of the three years in the period ended December 31, ~~2024~~2025, and the related notes (collectively referred to as the “consolidated financial statements”) of the Company, and our report dated February 2724, ~~2025~~2026, expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the ~~entity~~Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

AnA ~~entity~~company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. AnA ~~entity~~company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the ~~entity~~company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America, and that receipts and expenditures of the ~~entity~~company are being made only in accordance with authorizations of management and directors of the ~~entity~~company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the ~~entity~~company’s assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business

PDF Solutions, Inc. (the “Company” or “PDF”), provides products and services designed to empower organizations across the semiconductor and electronics ecosystem to connect, collect, manage, and analyze data about design, equipment, manufacturing, and test to improve the yield and quality of their products and operational efficiency. The Company’s products, services, and solutions include proprietary software, physical intellectual property (“IP”) for integrated circuit (“IC”) designs, electrical measurement hardware tools, proven methodologies, and professional services.

Basis of Presentation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries after the elimination of all significant intercompany balances and transactions.

Reclassification

Certain immaterial prior period amounts have been reclassified to conform with current period presentation with no effect on previously reported total assets, total liabilities, stockholders' equity or net income.

Change in Presentation of Revenues

As the Company’s business has evolved to include revenue from a broader portfolio of products and services, as a result of organic and inorganic expansion, beginning with this Annual Report on Form 10-K, the Company updated its presentation of revenue categories. Previously, the Company presented revenue in two categories: Analytics and Integrated Yield Ramp. Analytics revenue was derived from the following offerings: licenses and services for on-premise software, software-as-a-service (“SaaS”), licenses and purchase contracts for DirectScan™ systems (formerly known as “DFI systems”), and Characterization Vehicle® systems that did not include performance incentives based on customers’ yield achievement. Integrated Yield Ramp revenue was comprised of all fees from the Company’s contracts that included any performance incentives based on customers’ yield achievement. The Company now presents revenue in the following categories: Platform and Volume-based. Platform revenue is derived from the Company's following offerings: licenses for software (other than Cimetrix® runtime licenses) and related software maintenance and technical support services; SaaS; engineering services; fixed fees associated with CV® systems; and licenses and purchase contracts for DirectScan systems. Volume-based revenue is derived from Cimetrix runtime licenses, secureWISE® data, and Gainshare. See Note 2, “Revenue from Contracts with Customers.”

The change in presentation of revenues does not change the Company’s total revenues or total costs of revenues. The following table presents reclassified historical amounts to conform to the current period’s presentation (in thousands):

Use of Estimates

The preparation of consolidated financial statements in conformity with generally accepted accounting principles in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates in these consolidated financial statements include revenue recognition, the estimated useful lives of property and equipment and intangible assets, assumptions made in analysis of allowance for credit losses, fair values of assets acquired and liabilities assumed in business combinations, impairment of goodwill and long-lived assets, valuation for deferred tax assets, and accounting for lease obligations, stock-based compensation expense, and income tax uncertainties and contingencies. From time to time, the Company may enter into contingent fee arrangements with external legal firms that may represent the Company in legal proceedings related to disputes. The Company’s policy is to accrue contingent legal fees when they are probable and reasonably estimable. Actual results could differ from those estimates and may result in material effects on the Company’s operating results and financial position.

Concentration of Credit Risk

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, ~~short-term investments,~~ and accounts receivable. As of December 31, 2025 and 2024, and periodically throughout the year, the Company had cash balances in various operating accounts in excess of federally insured limits. The Company maintains its cash and cash equivalents ~~and short-term investments~~ with what it considers high credit quality financial institutions.

The Company primarily sells its products and services to companies in Asia, Europe, and North America within the semiconductor industry. As of December 31, ~~2024~~2025, ~~four~~two customers accounted for 5764% of the Company’s gross accounts receivable and ~~two~~three customers accounted for 3153% of the Company’s total revenues for ~~2024~~2025. As of December 31, ~~2023~~2024, ~~two~~four customers accounted for 5057% of the Company’s gross accounts receivable and ~~one~~two ~~customer~~customers accounted for 3531% of the Company’s total revenues for ~~2023~~2024. ~~Two~~One customer ~~customers~~ accounted for 41 35% of the Company’s revenues for ~~2022~~2023. See Note 1213, “Customer and Geographic Information” for further details. The Company does not require collateral or other security to support accounts receivable. To reduce credit risk, management performs ongoing credit evaluations of its customers’ financial condition. The Company maintains allowances for potential credit losses.

The allowance for credit losses, which was based on management’s best estimates, could be adjusted in the near term from current estimates depending on actual experience. Such adjustments could be material to the consolidated financial statements.

Table of Contents

Supplier Concentration

Some of the Company’s vendors provide highly specialized, differentiated products and services related to the Company’s ~~eProbe~~DirectScan system and some licensors provide key enabling software for the Company’s products and services. In the event any of these suppliers delay or discontinue providing such products and services to the Company, it may be difficult for the Company to replace such suppliers, software, or parts in a timely manner or at all, which could delay or make impossible the Company’s ability to deliver or adequately support its software systems or to complete and deliver its ~~eProbe~~DirectScan systems to its customers, and could negatively impact the Company’s future financial results of operations.

~~Cash and Cash Equivalents, and Investments~~ 59

~~The~~ Table ~~Company considers all highly liquid investments with effective maturities~~ of 90 days or less on the date of purchase to be cash equivalents. Investments with effective maturities greater than 90 days but less than one year are considered short-term investments, while investments with effective maturities greater than one year are considered long-term investments. The Company classifies its securities as available-for-sale investments and are carried at estimated fair value, with the unrealized gains and unrealized non-credit-related losses, net of tax, reported as a component of accumulated other comprehensive income (loss) in stockholders’ equity. Unrealized credit-related losses are recorded to interest and other expense (income), net in the Consolidated Statements of Comprehensive Income (Loss) with a corresponding allowance for credit-related losses in the Consolidated Balance Sheets. Realized gains and losses are based on the specific identification method and are included as a component of interest and other expense (income), net in the Consolidated Statements of Comprehensive Income (Loss).Contents

~~The Company periodically reviews its investments for impairment. For investments in unrealized loss positions~~Cash, Cash the Company assesses whether any portion of the decline in fair value below the amortized cost basis is due to credit-related factors if the Company neither intends to sell nor anticipates that it is more likely than not that it will be required to sell prior to recovery of the amortized cost basis. The Company considers factors such as the extent to which the market value has been less than the amortized cost basisEquivalents, ~~any noted failure of the issuer to make scheduled interest or principal payments, changes to the rating of the security by a rating agency~~ and other relevant credit-related factors in determining whether or not a credit loss exists.

Short-term investments consisted solely of U.S. Government securities and other current investments consisted of a non-marketable convertible promissory note. The cost of these securities approximated fair value and there was no material gross realized or unrealized gains or losses as of December 31, 2025 and 2024. See Note 14, “Fair Value Measurements” for further discussion on the Company’s investments.

The Company recorded interest income from its cash, cash equivalents, and short-term investments of $1.5 million, $5.6 million and $5.5 million for the years ended December 31, 2025, 2024 and 2023, respectively.

Accounts Receivable

Accounts receivable ~~include~~includes amounts that are unbilled at the end of the period that are expected to be billed and collected within a 12-‑month period. Unbilled accounts receivable are determined on an individual contract basis. Unbilled accounts receivable, included in accounts receivable, totaled $2344.0 8 million and $1623.40 million as of December 31, ~~2024~~2025 and ~~2023~~2024, respectively. Unbilled accounts receivable that are not expected to be billed and collected during the succeeding 12-‑month period are recorded in other non-current assets and totaled $98.0 7 million and $19.10 million as of December 31, ~~2024~~2025 and ~~2023~~2024, respectively.

The Company performs ongoing credit evaluations of its customers’ financial condition. An allowance for credit losses is maintained for probable credit losses based upon the Company’s assessment of the expected collectibility of the accounts receivable. The allowance for credit losses is reviewed on a quarterly basis to assess the adequacy of the allowance.

Property and Equipment

Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives (in years) of the related asset as follows:

Computer equipment		3
Software and capitalized software development cost		3-5
Furniture, fixtures, and equipment		5-10
Laboratory and test equipment		3-10
Leasehold improvements		Shorter of estimated useful life or term of lease


Computer equipment		3
Software and capitalized software development cost		3
Furniture, fixtures, and equipment		5-10

Leasehold improvements		Shorter of estimated useful life or term of lease

Intangible Assets

Intangible assets consist of acquired technology, certain contract rights, customer relationships, patents, trademarks and trade names. These intangible assets may be acquired through business combinations or direct purchases. Intangible assets are amortized on a straight-line basis over their estimated useful lives which range from one to ten years. The Company continually monitors events and changes in circumstances that could indicate carrying amounts of long-lived assets, including property and equipment and intangible assets, may not be recoverable. When such events or changes in circumstances occur, the Company assesses the recoverability of long-lived assets. Recoverability of an asset group is measured by comparison of its carrying amount to the expected future undiscounted cash flows that the asset group is expected to generate. If it is determined that an asset group is not recoverable, an impairment loss is recorded in the amount by which the carrying amount of the asset group exceeds its fair value.

Goodwill

The Company records goodwill when the purchase consideration of an acquisition exceeds the fair value of the net tangible and identified intangible assets as of the date of acquisition. The Company has one operating segment and one operating unit. The Company performs a qualitative analysis when testing a reporting unit’s goodwill for impairment. The Company performs an annual impairment assessment of goodwill during the fourth quarter of each calendar year or more frequently, if required to determine if any events or circumstances exist, such as an adverse change in business climate or a decline in the overall industry demand, that would indicate that it would more likely than not reduce the fair value of a reporting unit below its carrying amount, including goodwill. If events or circumstances do not indicate that the fair value of a reporting unit is below its carrying amount, then goodwill is not considered to be impaired and no further testing is required. If the carrying amount exceeds its fair value, an impairment loss would be recognized equal to the amount of excess, limited to the amount of total goodwill.

Leases

The Company has operating leases for administrative and sales offices, research and development laboratory and clean room. The Company recognizes long-term operating lease rights and commitments as operating lease right-of-use (“ROU”) assets, ~~operating lease liabilities~~ and operating lease liabilities, ~~non-current,~~ respectively, in the Consolidated Balance Sheets. The Company elected to not separate lease and non-lease components for all of its leases.

Table of Contents

The Company determines if an arrangement is, or contains, a lease at inception. Operating lease ROU assets, and operating lease liabilities are initially recorded based on the present value of lease payments over the lease term. Lease terms include the minimum unconditional term of the lease, and may include options to extend or terminate the lease when it is reasonably certain at the commencement date that such options will be exercised. The decision to include these options involves consideration of the Company’s overall future business plans and other relevant business economic factors that may affect its business. Since the determination of the lease term requires an application of judgment, lease terms that differ in reality from the Company’s initial judgment may potentially have a material impact on the Company’s Consolidated Balance Sheets. In addition, the Company’s leases do not provide an implicit rate. In determining the present value of the Company’s expected lease payments, the discount rate is calculated using the Company’s incremental borrowing rate determined based on the information available, which requires additional judgment.

Table of Contents

Software Development Costs

Internally developed software is software developed to meet the Company’s internal needs to provide certain services to the customers. The Company’s capitalized software development costs consist of internal compensation related costs and external direct costs incurred during the application development stage and are amortized over their useful lives, generally for five years.

The costs to develop software that is marketed externally consisting of external direct costs and internal compensation related costs are capitalized once technological feasibility of the software product has been established. Costs incurred prior to establishing technological feasibility are expensed as incurred. Technological feasibility is established when the Company has completed all planning, designing, coding, and testing activities that are necessary to establish that the software product can be produced to meet its design specifications. Capitalization of such costs ceases when the software product is generally available to customers. These software development costs are amortized using the greater of the straight-line method or the usage method over its estimated useful life.

Costs of Revenues

Costs of revenues consist primarily of costs incurred to provide and support the Company’s services, costs recognized in connection with licensing its software, information technology (“IT”) and facilities-related costs and amortization of acquired technology. Service costs include material costs, hardware costs (including cost of leased assets under sales-type leases), personnel-related costs (including compensation, employee benefits, bonus and stock-based compensation expense), subcontractor costs, overhead costs, travel, allocated facilities-related costs and product warranty expense. Software license costs consist of costs associated with cloud-delivery related expenses and licensing third-party software used by the Company in providing services to its customers in solution engagements or sold in conjunction with the Company’s software products.

Research and Development Expenses

Research and development expenses consist primarily of personnel-related costs (including compensation, employee benefits, bonus and stock-based compensation expense), outside development services, travel, third-party cloud-services related costs, IT and facilities cost allocations to support product development activities. Research and development expenses are charged to operations as incurred.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist primarily of personnel-related costs (including compensation, employee benefits, bonus, commission and stock-based compensation expense for sales, marketing and general and administrative personnel), legal, tax and accounting services, marketing communications and trade conference-related expenses, third-party cloud-services related costs, travel, IT and facilities cost allocations.

Stock-Based Compensation

The Company accounts for stock-based compensation using the fair value method, which requires the Company to measure stock-based compensation based on the grant-date fair value of the awards and recognize the compensation expense over the requisite service period. As stock-based compensation expense recognized is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Table of Contents

expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

The fair value of the Company’s restricted stock units (“RSUs”) is equal to the market value of the Company’s common stock on the date of the grant. These awards are subject to time-based vesting which generally occurs over a period of four years.

The fair value of the Company’s stock options and purchase rights granted under employee stock purchase plan is estimated using the Black-Scholes-Merton option-pricing model, which incorporates various assumptions including volatility, expected life and interest rates. The expected volatility is based on the historical volatility of the Company’s common stock over the most recent period commensurate with the estimated expected life of the Company’s stock options and purchase rights granted under employee stock purchase plan. The expected life is based on historical experience and on the terms and conditions of the stock options granted and purchase rights granted under employee stock purchase plan. The interest rate assumption is based upon observed Treasury yield curve rates appropriate for the expected life of the Company’s stock options and purchase rights granted under employee stock purchase plan.

Table of Contents

Income Taxes

The Company’s income tax expense comprises current tax liability and ~~change~~changes in deferred tax assets and liabilities. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax bases of assets and liabilities. The measurement of current and deferred tax assets and liabilities is based on provisions of enacted tax laws; the effect of future changes in tax laws or rates are not anticipated. Valuation allowances are provided to reduce deferred tax assets to an amount that in management’s judgment is more likely than not to be recoverable against future taxable income. No U.S. taxes are provided on earnings of non-U.S. subsidiaries, to the extent such earnings are deemed to be permanently invested. The Company’s income tax calculations are based on application of applicable U.S. federal and state or foreign tax laws. The Company’s tax filings, however, are subject to audit by the respective tax authorities. Accordingly, the Company recognizes tax liabilities based upon its estimate of whether, and the extent to which, additional taxes will be due when such estimates are more likely than not to be sustained. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. To the extent the final tax liabilities are different from the amounts originally accrued, the increases or decreases are recorded as income tax expense or benefit in the Consolidated Statements of Operations and Comprehensive Income (Loss).

Net Income (Loss) Per Share

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted net income (loss) per share is computed using the weighted average number of common shares outstanding for the period plus the potential effect of dilutive securities which are convertible into common shares (using the treasury stock method), except in cases in which the effect would be anti-dilutive. Dilutive potential common shares consist of incremental common shares issuable upon exercise of stock options, upon vesting of RSUs, contingently issuable shares for all periods and assumed issuance of shares under the Company’s employee stock purchase plan. No dilutive potential common shares are included in the computation of any diluted per share amount when a loss from continuing operations is reported by the Company.

Foreign Currency Translation

The functional currency of the Company’s foreign subsidiaries is the local currency for the respective subsidiary. The assets and liabilities are translated at the period-end exchange rate, and ~~statements~~Statements of ~~comprehensive~~Operations ~~income~~and Comprehensive Income (~~loss~~Loss) are translated at the average exchange rate during the year. Gains and losses resulting from foreign currency translations are included as a component of other comprehensive income (loss). Gains and losses resulting from foreign currency transactions are included in the Consolidated Statements of Operations and Comprehensive Income (Loss).

Business Combinations

The Company allocates the fair value of purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired based on their estimated fair values at the date of the business combination. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, estimated replacement costs and future expected cash flows from acquired customers, acquired technology, acquired patents, and trade names from a market participant perspective, useful lives and discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Allocation of purchase consideration to identifiable assets and liabilities affects the Company’s amortization expense, as acquired finite-lived intangible assets are amortized over their useful life, whereas any indefinite lived intangible assets, including in-process research and development, and goodwill, are not amortized but tested annually for impairment. During the measurement period, which is not to exceed one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings in the Consolidated Statements of Operations and Comprehensive Income (Loss).

Litigation

From time to time, the Company is subject to various claims and legal proceedings that arise in the ordinary course of business. The Company accrues for losses related to litigation when a potential loss is probable and the loss can be reasonably estimated, and recognizes gains related to litigation at the earlier of when the gain has been realized or when it is realizable in accordance with Financial Accounting Standards Board (“FASB”) requirements. See Note 78, “Commitments and Contingencies.”

Recently Issued Accounting Pronouncements Not Yet Adopted

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU is intended to improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. The ASU’s amendments are effective for public business entities for annual periods beginning after December 15, 2024. Entities are permitted to early adopt the standard for “annual financial statements that have not yet been issued or made available for issuance.” This ASU may be applied either prospectively or retrospectively. The Company will adopt this ASU on a prospective basis. The Company is currently evaluating the impact of the new standard on the consolidated financial statements and related disclosures.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This ASU requires the disaggregation of certain expenses in the notes to the consolidated financial statements, to provide enhanced transparency into the expense captions presented on the face of the income statement. This ASU is effective on a prospective basis for fiscal years beginning after December 15, 2026 and for interim periods beginning after December 15, 2027, with early adoption permitted.
