may not recoup our investments, which could cause our results to suffer. If our DFI system and Exensio software do not anticipate technological changes in our industry or fail to meet market demand, we may not capture the market share we anticipate, we may lose our competitive position, our products may become obsolete, and our business, financial condition or results of operations could be adversely affected. Additionally, our periodic research and development expenses may be independent of our level of revenue, which could negatively impact our financial results.

Current wording

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 system and Exensio and Sapience 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.

On-going negotiations and evaluation projects for new products, with new customers or in new markets may not result in significant revenues for us if we are unable to close new engagements on terms favorable to us, in a timely manner, or at all. Unexpected delays in our sales cycle could cause our revenues to fall short of expectations. 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, on occasion we have, 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.

Current wording

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.

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 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 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 including, for example, those made to combat the spread of COVID-19, 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.

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.

Previous wording

Our fixed-fee services, including for Characterization, 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. If we fail to meet a customer’s expectations, the customer could terminate their contract with us or claim that we breached our obligations, which could negatively affect our financial and operating results.

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 in the future, 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.

Previous wording

If the software, hardware, or proprietary technologies we provide to customers contain defects that negatively impact customers’ ability to use our systems or software, 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 or 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 technologies, hardware, or software tools could exceed our expectations. We have and may further incorporate AI solutions and related technologies for use in product development, or into our platform, offerings, services and features, and these applications may become important in our operations over time.

Previous wording

In the ordinary 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 again, 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. We recently started using third party AI/ML systems for research and development purposes. If these third-party AI/ML systems misuse or fail to properly protect the data we input, our use of such AI systems may result in the unauthorized disclosure of sensitive, proprietary, or confidential information belonging to us or our customers. For example, if the information we input into a third-party AI/ML system is used to train the underlying AI/ML models, such inputs could be revealed to others. The third-party AI/ML system 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 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 push for 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.

In 2024, we may continue to incur substantial additional expenses related to an arbitration hearing to resolve this matter. The loss of 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.

Export Regulations are fluid, complex, and uncertain, and there are ongoing efforts throughout the industry in coordination with regulators to revise, clarify, and interpret Export Regulations. The U.S. Congress and regulators continue to consider significant changes in laws and regulations. For example, the U.S. government is reportedly considering whether and/or how to impose restrictions directly on cloud-hosted services and further restrictions directly on U.S. person activity. We cannot predict the impact that additional legal changes may have on our business in the future. For example, in October 2022 the U.S. Bureau of Industry and Security (“BIS”) promulgated broad, novel Export Regulations relating to China that temporarily caused us to pause some deliveries while we interpreted the application of the new regulations on our business, given current and evolving operations. Also, BIS has placed certain entities on its entity list (the “Entity List”), which restricts supply of items to or in connection with the named entities. Further, in some circumstances Export Regulations require a license to export an item if the recipient will use the item to design or produce an item for a Huawei-affiliated company or certain other organizations on the Entity List. These regulations can also require licenses for exports that involve Chinese military or intelligence-related end users or end uses.

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 Integrated Yield Ramp 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 wafers and, in some cases, products our customers are able to make or sell, which would also decrease our Integrated Yield Ramp revenue. Also, our customers may unilaterally decide to 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 Integrated Yield Ramp revenue.

Current wording

Our Integrated Yield Ramp 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 Integrated Yield Ramp revenue due to these trends. Further, some of our manufacturing customers’ business is largely dependent on customers that use our manufacturing 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 Integrated Yield Ramp revenue will continue to decrease, which could negatively affect our financial results.

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 customers are global semiconductor companies, which means that our operations and performance depend significantly on worldwide economic conditions as well as semiconductor market specific changes. Uncertainty about global economic 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. Furthermore, 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, any economic and political uncertainty caused by the United States tariffs imposed on goods from China or enhanced U.S. export regulations relating to China, among other potential countries, and any corresponding tariffs from China or such other countries in response, may negatively impact demand and/or increase the cost for our 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.

Current wording

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. 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. 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.

Since our software requires certain 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.

Current wording

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 is 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.

Previous wording

We are exposed to risks related to information technology infrastructure, information management and protection, cybersecurity threats, and cyber incidents.

Current wording

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.

Previous wording

We face information technology security and fraud risks due to continued support of our employee’s remote or hybrid work environment, which may create additional information security vulnerabilities and/or magnify the impact of any disruption in our information technology systems. Our increased reliance on work-from-anywhere technologies and even our employees’ expanded reliance on company-approved bring-your-own-mobile-devices may increase the risk of cybersecurity or data breaches from possible circumvention of security and monitoring systems, 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 actions.

Current wording

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.

Previous wording

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 information 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 information technology and infrastructure that stores and processes our and our customers’ data is susceptible to continually evolving cybersecurity threats that become more

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.

Previous wording

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.

Current wording

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 tha…

Previous wording

We collect, use, store or disclose (collectively, “process”) 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 foreign laws regarding privacy and data security, as well as contractual commitments. Any failure or perceived failure by us to comply with such obligations may result in governmental enforcement actions, fines, litigation, 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 and business.

Current wording

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 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 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, 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.

accounts receivable, totaled $16.4 million and $13.5 million as of December 31, 2023 and 2022, 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 $1.1 million and $0.8 million as of December 31, 2023 and 2022, respectively. Two customers accounted for 50% of our gross accounts receivable as of December 31, 2023, and three customers accounted for 53% of our gross accounts receivable as of December 31, 2022. The total allowance for credit losses was $0.9 million as of December 31, 2023 and 2022. We generally do not require collateral or other security to support accounts receivable. Despite the financial ability of these customers to pay for on-going services by PDF under valid contracts, customers may delay payments. Our allowances for potential credit losses, if any, could be insufficient, and we may need to adjust our allowance for credit losses from current estimates or write-off receivables depending on such claims in the future. If we are forced to pursue legal remedies to collect receivables, our expenses could rise significantly and our business relationship and future business with these customers could suffer.

Current wording

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 $73.6 million and $44.9 million as of December 31, 2024 and 2023, respectively. Unbilled accounts receivable, included in accounts receivable, totaled $23.0 million and $16.4 million as of December 31, 2024 and 2023, 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 $9.0 million and $1.1 million as of December 31, 2024 and 2023, respectively. Four customers accounted for 57% of our gross accounts receivable as of December 31, 2024, and two customers accounted for 50% of our gross accounts receivable as of December 31, 2023. The total allowance for credit losses was $0.9 million as of December 31, 2024 and 2023.

Current wording

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.

Previous wording

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. The 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. The impact of releasing some or all of such valuation allowance in a future period could be a material benefit in the period in which such release occurs.
