Year-over-year tone shift - average net-tone change across Risk Factors and MD&A vs the prior 10-K. This filing is -0.70pp more bearish than last year's.
Why YoY instead of absolute: the LM lexicon has ~6.6× more negative words than positive (legal/risk-disclosure language is heavy on hedging), so every 10-K reads bearish on raw tone. Year-over-year change strips that bias and surfaces the actual shift in management's framing.

Item 1A. Risk Factors
You should carefully consider the risks described below. These risks are not the only risks that we may face. Additional risks and uncertainties that we are unaware of, or that we currently deem immaterial, also may become important factors that affect us. If any of the following risks occur, our business, financial condition or results of operations could be materially and adversely affected which could cause our actual operating results to differ materially from those indicated or suggested by forward-looking statements made in this Annual Report on Form 10-K or presented elsewhere by management from time to time.
Risks Related to our Business and Industry
We generate a large portion of our sales from a small number of customers. If we were to lose one or more of our large customers, operating results could suffer dramatically.
The semiconductor manufacturing industry is highly concentrated, with a relatively small number of large semiconductor manufacturers and contract test and assembly companies accounting for a substantial portion of the purchases of semiconductor equipment. Sales to our five largest customers accounted for approximately 77%, 93%, and 97% of our net sales in fiscal 2025, 2024, and 2023, respectively. During fiscal 2025, two customers accounted for approximately 39% and 15% of the Company’s net sales. During fiscal 2024, two customers accounted for approximately 67% and 17% of the Company’s net sales. During fiscal 2023, two customers accounted for approximately 79% and 10% of our net sales. No other customers accounted for more than 10% of our net sales for any of these periods.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis of the financial condition and results of operations should be read in conjunction with our “Selected Consolidated Financial Data” and our consolidated financial statements and related notes included elsewhere in this Annual Report on Form 10-K.
Overview
Aehr Test Systems (“Aehr Test”, “Aehr”, the “Company” or “We”) is a leading provider of test solutions for testing, burning-in, and stabilizing semiconductor devices in wafer level, singulated die, and package part form, and has installed thousands of systems worldwide. Decarbonization, generative AI and digitalization is driving increased quality, reliability, safety, and security needs of semiconductors used across multiple applications, including electric vehicles, electric vehicle charging infrastructure, solar and wind power, computing, data and telecommunications infrastructure, and solid-state memory and storage. This trend is driving additional test requirements, incremental capacity needs, and new opportunities for Aehr Test products and solutions.
We have developed and introduced several innovative products including the FOX-P family of test and burn-in systems and FOX WaferPak Aligner, FOX WaferPak Contactor, FOX DiePak Carrier and FOX DiePak Loader. The FOX-XP and FOX-NP systems are full wafer contact and singulated die/module test and burn-in systems that can test, burn-in, and a wide range of devices such as -edge silicon carbide-based and other power semiconductors, 2D and 3D sensors used in mobile phones, tablets, and other computing devices, memory semiconductors, processors, microcontrollers, systems-on-a-chip, and photonics and integrated optical devices. The FOX-CP system is a low-cost single-wafer compact test solution for logic, memory and photonic devices and the newest addition to the FOX-P product family. The FOX WaferPak Contactor contains a unique full wafer contactor capable of testing wafers up to 300mm that Integrated Circuit manufacturers to perform test, burn-in, and of full wafers on the FOX-P systems. The FOX DiePak Carrier allows testing, burning in, and of singulated bare die and modules up to 1,024 devices in parallel per DiePak on the FOX-NP and FOX-XP systems up to nine DiePaks at a time.
We expect that sales of our products to a limited number of customers will continue to account for a high percentage of our net sales for the foreseeable future. In addition, sales to particular customers may fluctuate significantly from quarter to quarter. The concentration of our customer base increases risks related to the financial condition of our customers, and the deterioration in financial condition of a single customer or the failure of a single customer to perform its obligations could have a material adverse effect on our results of operations and cash flow. If any such customers change their business requirements or focus, vendor selection, project prioritization, or purchasing behavior, or are parties to consolidation transactions, they may delay, suspend, reduce or cancel their purchases of our products or services and our business, financial condition, and results of operations may be adversely affected.
A substantial portion of our net sales is generated by relatively small volume, high value transactions.
We derive a substantial portion of our net sales from the sale of a relatively small number of systems with high dollar value. As a result, the loss or deferral of a limited number of system sales could have a material adverse effect on our net sales and operating results in a particular period. Most customer purchase orders are subject to cancellation or rescheduling by the customer with limited penalties, and, therefore, backlog at any particular date is not necessarily indicative of actual sales for any succeeding period. From time to time, cancellations and rescheduling of customer orders have occurred, and delays by our suppliers in providing components or subassemblies to us have caused delays in our shipments of our own products. For example, in the second half of fiscal 2025, global tariff announcements created uncertainty in the global economy that impacted customer demand and orders. There can be no assurance that we will not be materially adversely affected by future cancellations or rescheduling by our customers or other delays in our shipments.
In addition, a significant portion of our business is driven by demand for silicon carbide semiconductor devices, which are increasingly used in electric vehicles and related applications. If the growth of the electric vehicle market, or demand for silicon carbide semiconductor devices specifically, does not recover in the near future or experiences a prolongedslowdown, it could materially adversely affect our sales volumes, revenue growth, and overall operating results.
For non-standard products where we have not effectively demonstrated the ability to meet specifications in the customer environment, we defer revenue until we have met such customer specifications. Any delay in meeting customer specifications could have a material adverse effect on our operating results. A substantial portion of net sales typically are realized near the end of each quarter. A delay or reduction in shipments near the end of a particular quarter, due, for example, to unanticipated shipment rescheduling, cancellations or deferrals by customers, customer credit issues, unexpected manufacturing difficulties experienced by us or delays in deliveries by suppliers, could cause net sales in a particular quarter to fall significantly.
Table of Contents
The semiconductor equipment industry is intensely competitive. In each of the markets we serve, we face competition from established competitors and potential new entrants, many of which have greater financial, engineering, manufacturing and marketing resources than us.
Our FOX wafer-level and singulated die/module test and burn in systems and packaged part burn-in systems face competition from larger systems manufacturers that have significant technological know-how and manufacturing capability. Some users of our systems, such as independent test labs, build their own burn-in systems, while others, particularly large IC manufacturers in Asia, acquire burn-in systems from captive or affiliated suppliers. Our WaferPak products are facing and are expected to face increasing competition. Several companies have developed or are developing full-wafer and single-touchdown probe cards. The Company expects that its DiePak products for burning-in and testing multiple singulated die and small modules face significant competition. The Company believes that several companies have developed or are developing products which are intended to enable test and burn-in of multiple bare die, and small modules.
We expect our competitors to continue to improve the performance of their current products and to introduce new products with improved price and performance characteristics. New product introductions by our competitors or by new market entrants could cause a decline in sales or loss of market acceptance of our products. We have observed price competition in the systems market, particularly with respect to its less advanced products. Increased competitive pressure could also lead to intensified price-based competition, resulting in lower prices which could adversely affect our operating margins and results. We believe that to remain competitive we must invest significant financial resources in new product development and expand our customer service and support worldwide. There can be no assurance that we will be able to compete successfully in the future.
We rely on increasing market acceptance for our FOX and Sonoma systems, and we may not be successful in attracting new customers or maintaining our existing customers.
A principal element of our business strategy is to increase our presence in the test equipment market through system sales in our FOX wafer-level burn-in product family and Sonoma packaged parts burn-in solutions. Market acceptance of the FOX and Sonoma systems is subject to a number of risks. Before a customer incorporates the FOX or Sonoma system into a production line, lengthy qualification and correlation tests must be performed. We anticipate that potential customers may be reluctant to change their procedures in order to transfer burn-in and test functions to the FOX or Sonoma system. Initial purchases are expected to be limited to systems used for these qualifications and for engineering studies. Market acceptance of the FOX and Sonoma systems also may be affected by the reluctance of IC manufacturers to rely on relatively small suppliers such as us. As is common with new complex products incorporating leading-edge technologies, we may encounter reliability, design and manufacturing issues as we begin volume production and initial installations of FOX and Sonoma systems at customer sites. The failure of the FOX or Sonoma system to achieve increased market acceptance would have a material adverse effect on our future operating results.
We may experience increased costs associated with new product introductions.
As is common with new complex products incorporating leading-edge technologies, we have encountered reliability, design and manufacturing issues as we begin volume production and initial installations of certain products at customer sites. Some of these issues in the past have been related to components and subsystems supplied to us by third parties who have in some cases limited the ability of us to address such issues promptly. This process in the past required and in the future is likely to require us to incur un-reimbursed engineering expenses and to experience larger than anticipated warranty claims which could result in product returns. In the early stages of product development there can be no assurance that we will discover any reliability, design and manufacturing issues or, that if such issues arise, that they can be resolved to the customers’ satisfaction or that the resolution of such problems will not cause us to incur significant development costs or warranty expenses or to lose significant sales opportunities.
Our industry is subject to rapid technological change, and our ability to remain competitive and enter new markets depends on our ability to introduce new products in a timely manner.
The semiconductor equipment industry is subject to rapid technological change and new product introductions and enhancements. Our ability to remain competitive and expand into new markets depends in part upon our ability to develop new products and to introduce them at competitive prices and on a timely and cost-effective basis. We invest significant resources in research and development; however, there is no assurance that these efforts will result in commercially viable products or technologies that satisfy future customer needs.
Our success in developing new and enhanced products depends upon a variety of factors, including product selection, timely and efficient completion of product design, timely and efficient implementation of manufacturing and assembly processes, product performance in the field and effective sales and marketing. Because new product development commitments must be made well in advance of sales, new product decisions must anticipate both future demand and future technology advancements, which are inherently uncertain. Failure to innovate, delays in product development, or unsuccessful product launches could hinder our ability to enter new markets, negatively impacting our competitive position, revenue growth, and overall financial performance.

Furthermore, introductions of new and complex products typically involve a period in which design, engineering and reliability issues are identified and addressed by our suppliers and by us. Because of the complexity of our products, significant delays can occur between a product’s introduction and the commencement of the volume production of such product. We have experienced, from time to time, significant delays and technical and manufacturing difficulties with certain product introductions and may experience similar challenges in the future. Our inability to complete new product development, or to manufacture and ship products in time to meet customer requirements would materially adversely affect our business, financial condition and results of operations.
We are exposed to cybersecurity threats or incidents.
We collect, maintain, and transmit data on information systems. These systems include those owned and maintained by the Company or by third parties. In addition, we use cloud-based enterprise resource planning, ERP, software to manage the business integrating all facets of operations, including manufacturing, finance, and sales and marketing. The data maintained on these systems includes confidential and proprietary information belonging to us, our customers, suppliers, and others. While the Company devotes significant resources to protect its systems and data from unauthorized access or misuse, we are exposed to cybersecurity risks. Our systems are subject to computer viruses, data breach, phishing schemes, and other malicious software programs or attacks. We have experienced cyber threats and incidents in the past. Although past threats and incidents have not resulted in a material adverse effect, cybersecurity incidents may result in business disruption, loss of data, or unauthorized access to intellectual property which could adversely affect our business.
A decrease in customer device failure rates and future changes in semiconductor technologies may result in a decrease in demand for our products.
Customer tool utilization is driven by many factors including failure rates of customer devices. Improvements in yield may result in customers decreasing test and burn-in times, or electing to perform sampling rather than 100% burn-in of their devices. Based upon data obtained from our systems customers may revise internal manufacturing processes to decrease failure rates. A decrease in customer quality targets or tool utilization may result in a decrease in demand for our products impacting our business and results of operations.
Future improvements in semiconductor design and manufacturing technology may also reduce or eliminate the need for our products. For example, improvements in semiconductor process technology and improvements in conventional test systems, such as reduced cost or increased throughput, may significantly reduce or eliminate the market for one or more of our products. If we are not able to improve our products or develop new products or technologies quickly enough to maintain a competitive position in our markets, it could cause us to lose customers, substantially decrease or delay market acceptance and sales of our products and services, and significantly harm our business, financial condition, and results of operations.
If we fail to operate our business in accordance with our business plan, our operating results, business and stock price may be significantly and adversely impacted.
We attempt to operate our business in accordance with a business plan that is established annually, revised as appropriate, and reviewed by management even more frequently. Our business plan is developed based on a number of factors, many of which require estimates and assumptions, such as our expectations of the economic environment, future business levels, our customers’ willingness and ability to place orders, lead-times, and future revenue and cash flow. Our budgeted operating expenses, for example, are based in part on our future revenue expectations. However, our ability to achieve our anticipated revenue levels is a function of numerous factors, including the volatile and historically cyclical nature of our primary industry, customer order cancellations, macroeconomic changes, operational matters regarding particular agreements, our ability to manage customer deliveries, the availability of resources for the installation of our products, delays or accelerations by customers in taking deliveries and the acceptance of our products (for products where customer acceptance is required before we can recognize revenue from such sales), our ability to operate our business and sales processes effectively, and a number of the other risk factors as described in this Item 1A.
Because our expenses are in most cases relatively fixed in the short term, any revenue shortfall below expectations could have an immediate and material adverse effect on our operating results. Similarly, if we fail to manage our expenses effectively or otherwise fail to maintain rigorous cost controls, we could experience greater than anticipated expenses during an operating period, which would also negatively affect our results of operations. If we fail to operate our business consistent with our business plan, our operating results in any period may be materially and adversely impacted. Such an outcome could cause customers, suppliers or investors to view us as less stable, or could cause us to fail to meet financial analysts’ revenue or earnings estimates, any of which could have an adverse impact on our stock price.
Table of Contents
In addition, our management is constantly striving to balance the requirements and demands of our customers with the availability of resources, the need to manage our operating model and other factors. In furtherance of those efforts, we often must exercise discretion and judgment as to the timing and prioritization of manufacturing, deliveries, installations and payment scheduling. Any such decisions may impact our ability to recognize revenue, including the fiscal period during which such revenue may be recognized, with respect to such products, which could have a material adverse effect on our business, results of operations or stock price. Over the past few years, the Company has increased inventory levels significantly. This decision was driven by previously experienced long lead time in obtaining critical parts and in producing the systems and by higher projected revenues. As a result, if actual revenues do not meet these projections, the Company may face challenges related to excess inventory, including potential write-downs or obsolescence, which could adversely affect our financial results.
We are exposed to risks related to our commercial terms and conditions, including our indemnification of third parties, as well as the performance of our products.
Although our standard commercial documentation sets forth the terms and conditions that we intend to apply to commercial transactions with our business partners, counterparties to such transactions may not explicitly agree to our terms and conditions. In situations where we engage in business with a third party without an explicit master agreement regarding the applicable terms and conditions, or where the commercial documentation applicable to the transaction is subject to varying interpretations, we may have disputes with those third parties regarding the applicable terms and conditions of our business relationship with them. Such disputes could lead to a deterioration of our commercial relationship with those parties, costly and time-consuming litigation, or additional concessions or obligations being offered by us to resolve such disputes, or could impact our revenue or cost recognition. Any of these outcomes could materially and adversely affect our business, financial condition and results of operations.
In addition, in our commercial agreements, from time to time in the normal course of business, we indemnify third parties with whom we enter into contractual relationships, including customers, suppliers and lessors, with respect to certain matters.
We have agreed, under certain conditions, to hold these third parties harmless against specified losses, such as those arising from a breach of representations or covenants, third party claims that our products, when used for their intended purposes, infringe the IP rights of such third parties, or other claims made against certain parties. We may be compelled to enter into or accrue for probable settlements of alleged indemnification obligations, or we may be subject to potential liability arising from our customers’ involvements in legal disputes. In addition, notwithstanding the provisions related to limitations on our liability that we seek to include in our business agreements, the counterparties to such agreements may dispute our interpretation or application of such provisions, and a court of law may not interpret or apply such provisions in our favor, any of which could result in an obligation for us to pay material damages to third parties and engage in costly legal proceedings. It is difficult to determine the maximum potential amount of liability under any indemnification obligations, whether or not asserted, due to our limited history of prior indemnification claims and the unique facts and circumstances that are likely to be involved in any particular claim. Our business, financial condition and results of operations in a reported fiscal period could be materially and adversely affected if we expend significant amounts in defending or settling any purportedclaims, regardless of their merit or outcomes.
We are also exposed to potential costs associated with unexpected product performance issues. Our products and production processes are extremely complex and, thus, could contain unexpected product defects, especially when products are first introduced. Unexpected product performance issues could result in significant costs being incurred by us, including increased service or warranty costs, providing product replacements for (or modifications to) defective products, litigation related to defective products, reimbursement for damages caused by our products, product recalls, or product write-offs or disposal costs. These costs could be substantial and could have an adverse impact upon our business, financial condition and operating results. In addition, our reputation with our customers could be damaged as a result of such product defects, which could reduce demand for our products and negatively impact our business.
We may not be able to successfully integrate and manage acquired businesses.
Our success depends on our ability to continually enhance and broaden our product offerings in response to customer-anticipated process changes, strategic opportunities for growth, and industry technology trends. We may choose to acquire new and complementary businesses, products, technologies and/or services instead of developing them ourselves. If we are unable to successfully integrate and manage acquired businesses, if the costs associated with integrating the acquired business exceeds our expectations, or if acquired businesses perform poorly, then our business and financial results may suffer. It is possible that the businesses we have acquired may perform worse than expected or prove to be more difficult to integrate and manage than anticipated.

We are exposed to risks related to the use of artificial intelligence by us and our competitors.
We are increasingly incorporating AI capabilities into the development of our technologies. AI technology is complex and rapidly evolving, and may subject us to significant competitive, legal, regulatory and other risks. The implementation of AI can be costly and there is no guarantee that our use of AI will enhance our technologies, benefit our business operations or produce products and services that are preferred by our customers. Our competitors may be more successful in their AI strategy and develop superior products and services with the aid of AI.
Additionally, AI algorithms or training methodologies may be flawed, and datasets may contain irrelevant, insufficient or biased information, which can cause errors in outputs. This may give rise to legal liability, damage our reputation and materially harm our business. We may not be able to control the development, maintenance or behavior of third-party AI solutions or how their providers obtain or otherwise process data, and these AI solutions may be used inappropriately or irresponsibly. There is no guarantee that any contractual or other protections we seek to implement will be sufficient to protect us from risks presented by these solutions. Additionally, the use of AI in the development of our products and services, and our customers’ use of AI in relation to our products and services could also cause loss of intellectual property (“IP”), as well as subject us to risks, including third-party claims, related to IP infringement or misappropriation, data privacy and cybersecurity. Additionally, concerns over the use of AI for purposes contrary to public interests could impair public acceptance of AI and affect demand for our products and services. Furthermore, the United States and other countries may adopt laws and regulations related to AI. Such new laws and regulations may be interpreted in ways that conflict with or otherwise impact our approach to AI and use of AI solutions, could cause us to incur greater compliance costs and may limit the use of AI in the development of our products and services. Any failure or perceived failure by us to comply with such regulatory requirements could subject us to legal liabilities, damage our reputation, or otherwise have a material and adverse impact on our business.
Operational and Other Risks
We purchase materials from suppliers worldwide, which subjects the Company to increased risk; t ariff uncertainty, trade restrictions, and global supply chain risks could adversely affect our business.
We purchase components, sub-assemblies, and chambers from suppliers outside the United States. Increases in tariffs, uncertainty surrounding current and future tariff regulations, additional taxes, rising inflation in the supply chain or new trade barriers may result in an increase in our manufacturing costs. Fluctuations in tariff and trade policies, particularly those that may change without significant notice, create instability in our supply chain and limit our ability to plan for future cost structures. A decrease in the value of the U.S. Dollar relative to foreign currencies would increase the cost of our materials. Should the Company increase its sales prices to recover the increase in costs, this could result in a decrease in the competitiveness of our products. In addition, we are subject to other risks associated with purchasing materials from suppliers worldwide. Government authorities may also implement protectionist policies or impose limitations on the transfer of intellectual property. This may limit our ability to obtain products from certain geographic regions and require us to identify and qualify new suppliers. The process of qualifying suppliers could be lengthy, and no assurance can be given that any additional sources would be available to us on a timely basis. Changes in trade relations, tariff structures, currency fluctuations, or protectionist policies could have a material adverse effect on our business, financial condition or results of operations.
Supply chain issues, including a shortage of critical components or contract manufacturing capacity, could result in a delay in fulfillment of customer orders, or an increase in costs, resulting in an adverse impact on our business and operating results.
Our sales growth depends on our ability to obtain timely deliveries of parts from our suppliers and contract manufacturers. A market shortage of semiconductor and other component supply could affect lead times, the cost of supply, and our ability to meet customer demand for our products. While we have taken steps to obtain an assurance of supply from our key suppliers, the market shortage of semiconductor supply may impact our ability to meet customer order fulfillments, or result in a significant increase in costs of our inventories. Manufacturing issues or capacity problems experienced by our suppliers or contract manufacturers could impact our ability to secure sufficient supply of critical components. If there is a market shortage of semiconductor supply, suppliers and contract manufacturers may commit their capacity to others, limiting our supplies or increasing costs. The failure to obtain timely delivery of supplies, or a significant increase in costs, could result in a material impact in our business and results from operations.
We sell our products and services worldwide, and our business is subject to risks inherent in conducting business activities in geographic regions outside of the United States.
Approximately 70%, 95%, and 86% of our net sales in fiscal 2025, 2024, and 2023, respectively, were attributable to sales to customers for delivery outside of the United States. We provide sales and service globally with resources in North America, Taiwan, Germany, Japan, South Korea, and a service organization in the Philippines, as well as direct support through third party agreements in China. We expect that sales of products for delivery outside of the United States will continue to represent a substantial portion of our future sales. Our future performance will depend, in significant part, upon our ability to continue to compete in foreign markets which in turn will depend, in part, upon a continuation of current trade relations between the United States and foreign countries in which semiconductor manufacturers or assemblers have operations. A change toward more protectionist trade legislation in either the United States or such foreign countries, such as a change in the current tariff structures, export compliance or other trade policies, could adversely affect our ability to sell our products in foreign markets. In addition, we are subject to other risks associated with doing business internationally, including longer receivable collection periods and greaterdifficulty in accounts receivable collection, the burden of complying with a variety of foreign laws, difficulty in staffing and managing global operations, risks of civil disturbance or other events which may limit or disrupt markets, international exchange restrictions, changing political conditions and monetary policies of foreign governments.
Table of Contents
Our net sales for fiscal 2025 were primarily denominated in U.S. Dollars. However, because a substantial portion of our net sales is from sales of products for delivery outside the United States, an increase in the value of the U.S. Dollar relative to foreign currencies would increase the cost of our products compared to products sold by local companies in such markets. In addition, since the price is determined at the time a purchase order is accepted, we are exposed to the risks of fluctuations in the U.S. Dollar exchange rate during the lengthy period from the date a purchase order is received until payment is made. This exchange rate risk is partially offset to the extent our foreign operations incur expenses in the local currency. To date, we have not invested in any instruments designed to hedge currency risks. Our operating results could be adversely affected by fluctuations in the value of the U.S. Dollar relative to other currencies.
Global unrest may impact our ability to sell our products or obtain critical materials.
Global economic uncertainty and financial market volatility caused by political instability, changes in international trade relationships and conflicts, such as the conflict between Russia and Ukraine and the political climate in China and Taiwan, the Israel-Hamas war, the Israel-Iran conflict and the tensions in the Red Sea in connection with the attacks to disrupt shipments may result in limited access to these markets for sales and material purchases. Periods of macroeconomic weakness or recession and heightened market volatility caused by adverse geopolitical developments could increase these risks, potentially resulting in adverse impacts on our business operations. Increased energy costs in Europe, resulting from Russia’s limiting energy supplies in the region, may result in an economic downturn or an increase in the cost of materials. The on-going decline in relations between the United States and China, and relations between China and Taiwan, may result in the imposition of trade restrictions with China or Taiwan. While we have limited sales in Europe and Taiwan, and procurement from these regions, unrest in these areas may result in a decrease in sales of our products, or an increase in costs of materials and services.
Geopolitical tensions and changes in government trade policies could adversely affect our operations in China and our business, results of operations and financial condition.
Heightened geopolitical tensions between the United States and China could create barriers to selling our products and services to customers in China as there is currently significant uncertainty about the future relationship between the United States and China with respect to trade policies, treaties, tariffs and taxes. These barriers include increased tariffs and other trade barriers, regulatory restrictions, or limitations on technology transfer. These tariffs, and the related geopolitical uncertainty between the United States and China, may cause decreased demand for our products or increase cost of components used in our products, which could have a material adverse effect on our business, results of operations and financial condition. Additionally, any such developments, including changes in trade policies, export and import restrictions, or diplomatic relations under the current or future administrations, could impact economic activity and lead to a general contraction of customer demand and could adversely affect our ability to compete in the Chinese market, impairing our growth prospects in China.
Our dependence on subcontractors and sole source suppliers may prevent us from delivering our products on a timely basis and expose us to intellectual property infringement.
We rely on subcontractors to manufacture many of the components or subassemblies used in our products. Our FOX systems, WaferPak Contactors, DiePak Carriers, WaferPak Aligners, and DiePak Loaders contain several components, including environmental chambers, power supplies, high-density interconnects, wafer contactors, module contactors, signal distribution substrates, and certain ICs that are currently supplied by only one or a limited number of suppliers. Our reliance on subcontractors and single source suppliers involves a number of significant risks, including the loss of control over the manufacturing process, the potential absence of adequate capacity and reduced control over delivery schedules, manufacturing yields, quality and costs. In the event that any significant subcontractor or single source supplier is unable or unwilling to continue to manufacture subassemblies, components or parts in required volumes, we would have to identify and qualify acceptable replacements. The process of qualifying subcontractors and suppliers could be lengthy, and no assurance can be given that any additional sources would be available to us on a timely basis. Any delay, interruption or termination of a supplier relationship could adversely affect our ability to deliver products, which would harm our operating results.
Table of Contents
Our suppliers manufacture components, tooling, and provide engineering services. During this process, our suppliers are allowed access to our intellectual property. While we maintain patents to protect from intellectual property infringement, there can be no assurance that technological information gained in the manufacture of our products will not be used to develop a new product, improve processes or techniques which compete against our products. Litigation may be necessary to enforce or determine the validity and scope of our proprietary rights, and there can be no assurance that our intellectual property rights, if challenged, will be upheld as valid.
Tightening of fiscal monetary policy, and periodic economic and semiconductor industry downturns could negatively affect our business, results of operations and financial condition.
The current economic conditions and uncertainty about future economic conditions, including volatility in the financial markets, national debt, fiscal or monetary concerns, inflation and interest rates, bank failures, and economic recession, make it challenging for us to forecast our operating results, make business decisions, and identify the risks that may affect our business, financial condition and results of operations. The market for semiconductors and semiconductor capital equipment has historically been cyclical, and we expect this trend to continue in the future. If we do not appropriately manage our business operations in response to changing economic and industry conditions, it could have a material and adverse impact on our business performance and financial condition.
Our net sales are affected by the cyclicality of the semiconductor market, which may have a material adverse impact on our business performance and financial condition.
A significant portion of our business depends upon the capital expenditures of semiconductor manufacturers. Capital expenditures by these companies depend upon, among other things, the current and anticipated market demand for semiconductors and the products that utilize them. Typically, semiconductor manufacturers curtail capital expenditures during periods of economic downturn. Conversely, semiconductor manufacturers increase capital expenditures when market demand requires the addition of new or expanded production capabilities. This cyclicality may have a material adverse impact on our business performance and financial condition.
We have been and may in the future be subject to litigation relating to intellectual property infringement which would be time-consuming, expensive and a distraction from our business.
If we do not adequately protect our intellectual property, competitors may be able to use our proprietary information to erode our competitive advantage, which could harm our business and operating results. Litigation may be necessary to enforce or determine the validity and scope of our proprietary rights, and there can be no assurance that our intellectual property rights, if challenged, will be upheld as valid. Such litigation could result in substantial costs and diversion of resources and could have a material adverse effect on our operating results, regardless of the outcome of the litigation. In addition, there can be no assurance that any of the patents issued to us will not be challenged, invalidated or circumvented or that the rights granted thereunder will provide competitive advantages to us. For a description of the infringement proceedings in China seeking to protect two of our patents, see Note 9, “Commitments and Contingencies” in the Notes to Consolidated Financial Statements.
There are no pending claimsagainst us regarding infringement of any patents or other intellectual property rights of others. However, in the future we may receive communications from third parties asserting intellectual property claimsagainst us. Such claims could include assertions that our products infringe, or may infringe, the proprietary rights of third parties, requests for indemnification against such infringement or suggestions that we may be interested in acquiring a license from such third parties. There can be no assurance that any such claim will not result in litigation, which could involve significant expense to us, and, if we are required or deem it appropriate to obtain a license relating to one or more products or technologies, there can be no assurance that we would be able to do so on commercially reasonable terms, or at all.
We cannot assure that we have complied with all applicable environmental laws, and our failure to do so could adversely affect our business as a result of having to pay substantial amounts in damages or fees.
Federal, state and local regulations impose various controls on the use, storage, discharge, handling, emission, generation, manufacture and disposal of toxic and other hazardous substances used in our operations. We believe that our activities conform in all material respects to current environmental and land use regulations applicable to our operations and our current facilities, and that we have obtained environmental permits necessary to conduct our business. Nevertheless, failure to comply with current or future regulations could result in substantial fines, suspension of production, alteration of our manufacturing processes or cessation of operations. Such regulations could require us to acquire expensive remediation equipment or to incur substantial expenses to comply with environmental regulations. Any failure to control the use, disposal or storage of or adequately restrict the discharge of, hazardous or toxic substances could subject us to significant liabilities.

The failure to successfully implement enterprise resource planning and other information systems changes could adversely impact our business and operating results.
We periodically implement new or enhanced enterprise resource planning and related information systems in order to better manage our business operations, align our global organizations and enable future growth. Implementation of new business processes and information systems requires the commitment of significant personnel, training and financial resources, and entails risks to our business operations. If we do not successfully implement enterprise resource planning and related information systems improvements, or if there are delays or difficulties in implementing these systems, we may not realize anticipated productivity improvements or cost efficiencies, and may experience interruptions in service and operational difficulties, which could result in quality issues, reputational harm, lost market and revenue opportunities, and otherwise adversely affect our business, financial condition and results of operations.
Risks Related to Ownership of our Common Stock
Our stock price is volatile.
Historically, our common stock has experienced substantial price volatility. For example, during the two-year period ended May 30, 2025, the price of our common stock has ranged from $6.27 to $54.10. If our future operating results or margins are below the expectations of stock market analysts or our investors, our stock price will likely decline. Factors such as announcements of developments related to our business, fluctuations in our operating results, general conditions in the semiconductor and semiconductor equipment industries as well as the worldwide economy, announcement of technological innovations, new systems or product enhancements by us or our competitors, fluctuations in the level of cooperative development funding, acquisitions, changes in governmental regulations, developments in patents or other intellectual property rights and changes in our relationships with customers and suppliers could cause the price of our common stock to fluctuate substantially. In addition, in recent years the stock market in general, and the market for small capitalization and high technology stocks in particular, have experienced extreme price fluctuations which have often been unrelated to the operating performance of the affected companies. Such fluctuations could adversely affect the market price of our common stock.
We are exposed to risks associated with shareholder class action lawsuits, which are expensive and could divert management attention.
On December 3, 2024, a shareholder class action lawsuit, captioned Lucid Alternative Fund, LP v. Aehr Test Systems, Inc. was filed in the United States District Court for the Northern District of California, alleging that we and certain of our executives made false and misleading statements regarding our earnings guidance and other financial projections for 2024. Additionally, two shareholder derivative complaints were filed, allegingbreaches of fiduciary duties and other misconduct by certain directors and officers of the Company. On May 16, 2025, the court-appointed lead plaintiff voluntarily dismissed the class action lawsuit, and on June 9, 2025, the court dismissed the derivative action without prejudice.
While these lawsuits have been resolved without adverse judgments, there is no assurance that we will not face similar litigation in the future. Defendingagainst shareholder class actions or derivative lawsuits can be costly, disruptive, and time-consuming, and may divert the attention of our management and Board of Directors. Such proceedings, regardless of their outcome, could also harm our reputation, impact investor confidence, and result in increased scrutiny of our public disclosures, internal controls, and corporate governance practices. If we are subject to future litigation and do not prevail, we could be required to pay substantial damages or incur other significant costs, which could materially adversely affect our financial condition, results of operations, and cash flows.
Risks Related to our Financial/Legal/Organizational Structure
We depend on our key personnel and our success depends on our ability to attract, retain and motivate talented employees.
Our success depends to a significant extent upon the continued service of Gayn Erickson, our President and Chief Executive Officer, as well as other executive officers and key employees. We do not maintain key person life insurance for our benefit on any of our personnel, and none of our employees are subject to a non-competition agreement with us. The loss of the services of any of our executive officers or a group of key employees could have a material adverse effect on our business, financial condition and operating results. Our future success will depend in significant part upon our ability to attract, retain and motivating highly skilled technical, management, sales and marketing personnel. There are a limited number of personnel with the requisite skills to serve in these positions, and it has become increasingly difficult for us to hire such personnel. Competition for such personnel in the semiconductor equipment industry is intense, and there can be no assurance that we will be successful in attracting, retaining or motivating such personnel. Changes in management could disrupt our operations and adversely affect our operating results.

If we fail to maintain effective internal control over financial reporting in the future, the accuracy and timing of our financial reporting may be adversely affected.
We are required to comply with Section 404 of the Sarbanes-Oxley Act of 2002. The provisions of the act require, among other things, that we maintain effective internal control over financial reporting and disclosure controls and procedures. Preparing our financial statements involves a number of complex processes, many of which are done manually and are dependent upon individual data input or review. These processes include, but are not limited to, calculating revenue, deferred revenue and inventory costs. While we continue to automate our processes and enhance our review and put in place controls to reduce the likelihood for errors, we expect that for the foreseeable future, many of our processes will remain manually intensive and thus subject to human error.
Compliance with federal securities laws, rules and regulations, as well as NASDAQ requirements, has become increasingly complex, and the significant attention and expense we must devote to those areas may have an adverse impact on our business.
Federal securities laws, rules and regulations, as well as NASDAQ rules and regulations, require companies to maintain extensive corporate governance measures, impose comprehensive reporting and disclosure requirements, set strict independence and financial expertise standards for audit and other committee members and impose civil and criminalpenalties for companies and their chief executive officers, chief financial officers and directors for securities law violations. It is anticipated that the rules and regulations applicable to public companies have increased and will continue to increase substantially the legal and financial compliance costs incurred by us and make some activities more time-consuming and costly. If these requirements divert the attention of our management and personnel from other business concerns, they could have an adverse effect on our business.
A change in accounting standards or practices or a change in existing taxation rules or practices (or changes in interpretations of such standards, practices or rules) could have a significant effect on our reported results and may affect reporting of transactions completed before the change is effective.
New accounting standards and taxation rules and varying interpretations of accounting pronouncements and taxation rules have occurred and will continue to occur in the future. Changes to (or revised interpretations or applications of) existing accounting standards or tax rules or the questioning of current or past practices may adversely affect our reported financial results or the way we conduct our business. Adoption of new standards may require changes to our processes, accounting systems, and internal controls. Difficulties encountered during adoption could result in internal control deficiencies or delay the reporting of our financial results.

Following the acquisition of Incal, our product portfolio further expanded to include packaged parts burn-in solutions for the full range of power and complexity of integrated circuits. Incal’s product lines feature the Sonoma series for ultra-high-power burn-in testing, the Tahoe series for medium-power reliability burn-in, and the Echo series for low-power and high parallelism testing. The Sonoma line, with its ultra-high-power capabilities, is specifically designed to address the reliability and burn-in needs of the burgeoning demand for AI accelerators, GPUs, HPC processors, and devices that can reach levels of power as high as 1600W. The Sonoma is available in its standard configuration, which hosts up to 22 slots per chamber. The Tahoe and Echo lines for medium-power and low-power burn-in solutions, respectively, target logic, SoC, and mixed-signal devices employed in mobile communications, mobility, medical, military, aerospace, and data center applications. These systems are frequently used by independent test and burn-in labs, as well as semiconductor manufacturers.
Our revenue consists primarily of sales of FOX-P systems, WaferPak Aligners and DiePak Loaders, WaferPak Contactors, DiePak Carriers, packaged parts burn-in systems, test fixtures, upgrades and spare parts, service contracts revenues, and non-recurring engineering charges. Our selling arrangements may include contractual customer acceptance provisions, which are mostly deemed perfunctory or inconsequential, and installation of the product occurs after shipment, transfer of title and risk of loss.
Critical Accounting Policies and Estimates
Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”). The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenues, inventories, income taxes, the business combination with Incal, and the impairment of goodwill and long-lived assets, among others. Our estimates are derived from historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Those results form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements.
Table of Contents
Revenue Recognition
We recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services by following a five-step process: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price, and (5) recognize revenue when or as we satisfy a performance obligation, as further described below.
Performance obligations include sales of systems, contactors, spare parts, and services, as well as installation and training services included in customer contracts. A contract’s transaction price is allocated to each distinct performance obligation. In determining the transaction price, we evaluate whether the price is subject to refund or adjustment to determine the net consideration to which we expect to be entitled. We generally do not grant return privileges, except for defective products during the warranty period.
For contracts that contain multiple performance obligations, we allocate the transaction price to the performance obligations on a relative standalone selling price basis. Standalone selling prices are based on multiple factors including, but not limited to, historical discounting trends for products and services and pricing practices in different geographies. Revenue for systems and spares is recognized at a point in time, which is generally upon shipment or delivery and evidenced by transfer of title and risk of loss to the customer. Revenue from services is recognized over time as the customer receives the benefit over the contractual period of generally one year or less.
We have elected the practical expedient to not assess whether a contract has a significant financing component as our standard payment terms are less than one year.
We sell our products primarily through a direct sales force. In certain international markets, we sell our products through independent distributors.
Inventory Valuation
We write down the carrying value of our inventory to net realizable value for estimated obsolescence or unmarketable inventory in an amount equal to the difference between the cost of inventory and its estimated realizable value based upon assumptions about future demand and market conditions. We assess the valuation of all inventories, including raw materials, work-in-process, finished goods and spare parts on a periodic basis.
Obsolete inventory or inventory in excess of our estimated usage is written down to its estimated market value less costs to sell, if less than its cost. The inventory write-downs are established on the basis of obsolete inventory or specifically identified inventory in excess of established usage. Inherent in our estimates of demand and market value in determining inventory valuation are estimates related to economic trends, market conditions, and future demand for our products. If actual demand and market conditions are less favorable than our projections, additional inventory write-downs may be required. If the inventory value is written down to its net realizable value, and subsequently there is an increased demand for the inventory at a higher value, the increased value of the inventory is not realized until the inventory is sold either as a component of a system or as separate inventory.
Income Taxes
The determination of our tax provision is highly dependent upon the geographic composition of worldwide earnings and tax regulations governing each region and is subject to judgments and estimates. Management carefully monitors the changes in many factors and adjusts the effective tax rate as required.
We assess the likelihood that we are able to recover our deferred tax assets. If recovery is not more likely than not, we increase our provision for taxes by recording a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be recoverable. In determining whether the realization of these deferred tax assets is impaired, we make judgments with respect to whether we are likely to generate sufficient future taxable income to realize these assets. In order to reverse the valuation allowance, management considers both positive and negative evidence and determines that there is sufficient positive evidence to conclude that it is more likely than not that the deferred tax assets will be realized. In fiscal 2024, we released the entire valuation allowance which contributed to the tax benefit of approximately $20.7 million for the year ended May 31, 2024.

Business Combination
Accounting for business combinations requires management to make significant estimates and assumptions to determine the fair values of assets acquired and liabilities assumed at the acquisition date. The assumptions and estimates are based, in part, on historical experience and information obtained from management of the acquired company and are inherently uncertain. Critical estimates in valuing certain acquired intangible assets include, but are not limited to, future expected cash flows including revenue growth rate assumptions from product sales, customer orders and acquired technologies, estimated royalty rates used in valuing technology-related intangible assets, and discount rates. The discount rates used to discount expected future cash flows to present value are typically derived from a weighted-average cost of capital analysis and adjusted to reflect inherent risks. Unanticipated events and circumstances may occur that could affect either the accuracy or validity of such assumptions, estimates or actual results.
Impairment of Goodwill
We assess goodwill for impairment annually during our fourth fiscal quarter or whenever events or changes in circumstances indicate the carrying value may not be fully recoverable. The process of evaluating the potential impairment of goodwill requires significant judgment. We may first evaluate qualitative factors to assess if it is more likely than not that the fair value of a reporting unit is less than its carrying amount and to determine if an impairment test is necessary. We may choose to proceed directly to the quantitative impairment test, bypassing the initial qualitative assessment. The quantitative test compares the fair value of the reporting unit to its carrying value, including goodwill allocated to that reporting unit. A goodwill impairmentloss would be the amount by which a reporting unit’s carrying value exceeds its fair value, however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. There were no impairments to goodwill during the fiscal year ended May 30, 2025.
Impairment of Long-Lived Assets
We monitor the carrying value of long-lived assets for potential impairment each quarter based on whether certain triggering events have occurred. These events include current period losses combined with a history of losses, or a projection of continuing losses, or a significant decrease in the market value of an asset. When a triggering event occurs, we perform an impairment calculation, comparing projected undiscounted cash flows, utilizing current cash flow information and expected growth rates, to the carrying value of the assets. If we identify impairment for long-lived assets to be held and used, we compare the assets’ current carrying value to the assets’ fair value. Fair value is determined based on market values or discounted future cash flows. We record impairment when the carrying value exceeds fair market value.
During the year ended May 30, 2025, the Company recognized an impairment charge of $0.5 million related to the right-of-use asset and $0.1 million related to leasehold improvements in connection with the closure of the Incal office and the consolidation of facilities. The impairment charge is included in restructuring changes in the consolidated statement of operations. During the years ended May 31, 2024 and May 31, 2023, the Company did not record any impairment of long-lived assets.

Revenue
Revenue decreased by $7.3 million in fiscal year 2025 over fiscal year 2024 driven by a decrease in shipments of our systems and contactors primarily due to the continued softness in the power semiconductor demand for electric vehicles. Our product revenue decreased by $8.9 million due to the decrease in our contactors revenue and FOX-P systems revenue, which was partially offset by the increase in package parts burn-in product revenue in connection with the Incal acquisition. The decline in product revenue was partially offset by an increase in services revenue of $1.7 million.
Revenue increased by $1.3 million in fiscal year 2024 over fiscal year 2023, primarily driven by higher sales in our contactors. Our contactors revenue increased by $15.7 million, and our services revenue increased by $0.3 million. The increase was partially offset by a decrease in systems revenue of $14.7 million.

On a geographic basis, revenues represent products that were shipped to or services that were performed at our customer locations. For fiscal year 2025, revenue declined in Asia primarily due to continued softness in the power semiconductor demand for electric vehicles. This decline was partially offset by revenue growth in the United States, driven by much higher systems and contactors sales to customers that focus on the artificial intelligence market.
For fiscal year 2024, total revenues increased compared to the same period in the prior year due to an increase in international revenues as a result of more shipments to our customers in Europe and Asia, partially offset by the decline in revenue from a customer in the United States.

As a percentage of total revenues
Research and development expenses consist primarily of compensation and benefits for product development personnel, outside development service costs, travel expenses, facilities cost allocations, and stock-based compensation charges. Research and development expenses increased by $1.7 million in fiscal year 2025 over fiscal year 2024 primarily due to the severance benefits incurred following the death of an executive officer, higher employee costs and stock-based compensation expense resulting from growth in engineering headcount, and additional research and development expenses from the newly acquired Incal business. The increase was partially offset by lower non-recurring engineering service charges.
Research and development expenses increased by $1.6 million in fiscal year 2024 over fiscal year 2023 primarily due to higher employment-related costs because of an increase in headcount, higher non-recurring engineering services charges, an increase in allocated facility cost and an increase in recruiting expenses.

Income tax benefit was $0.4 million in fiscal year 2025, compared to income tax benefit of $20.7 million in fiscal year 2024. In fiscal 2025, the Company recognized an income tax benefit due to year-to-date operating losses in the United States. Income tax benefit was $20.7 million in fiscal year 2024, compared to income tax expense of $60 thousand in fiscal year 2023. A significant income tax benefit in fiscal year 2024 was recognized primarily due to the release of a valuation allowance of $21.9 million, as management determined that there was sufficient positive evidence to conclude that it is more likely than not that the deferred tax assets will be realized, which was partially offset by income tax expense of $1.2 million in fiscal year 2024.
Liquidity and Capital Resources
Cash, cash equivalents, and restricted cash were $26.5 million as of May 30, 2025, compared to $49.3 million as of May 31, 2024.

Net Cash Flows Provided by (Used in) Operating Activities
Cash flow used in operating activities during fiscal year 2025 mostly consisted of net loss, adjusted for certain non-cash items which primarily consisted of depreciation and amortization, stock-based compensation expense and amortization of operating lease right-of-use assets. The $9.2 million decrease in cash flows from operating activities in fiscal year 2025, compared to fiscal year 2024, was driven primarily by lower adjusted net income, excluding non-cash items, in the current period compared to the prior period, a decrease in cash provided by the collection of accounts receivable due to lower revenue and slower collection, and an increase in unbilled receivables and prepayments, which were partially offset by the decrease in cash used in procuring inventory and payments to vendors, and an increase in deferred revenue due to timing of customer deposits and revenue recognition.
The $8.3 million decrease in cash flows from operating activities for fiscal year 2024, compared to fiscal year 2023, was driven primarily by an increase in cash used in inventory production and vendor payments due to anticipated customer demand, lower net income after non-cash adjustments and a decrease in cash provided by deferred revenue due to timing of customer deposits and revenue recognition, partially offset by an increase in cash provided by collection of accounts receivable.
Net Cash Flows Provided by (Used in) Investing Activities
Net cash used in investing activities was $16.1 million for the fiscal year 2025 compared to net cash provided by investing activities of $17.3 million for the fiscal year 2024. The increase in net cash used was primarily due to the maturity of our short-term investments of $18.0 million during the fiscal year 2024, while there was no such maturity of investment during the fiscal year 2025. Additionally, the Company paid $11.1 million to acquire Incal, and increased its spending on property and equipment by $4.2 million, primarily related to office renovation during the fiscal year 2025.
Net cash provided by investing activities was $17.3 million for fiscal year 2024, compared to net cash used in investing activities of $18.7 million for fiscal year 2023. The increase was primarily due to the maturity of our short-term investments of $18.0 million during fiscal year 2024, while there was a net purchase of short-term investments of $17.3 million during fiscal year 2023. Capital expenditure in fiscal 2024, and 2023 was $0.7 million and $1.4 million, respectively. Capital expenditure was primarily for acquisition of testing equipment and manufacturing equipment.
Net Cash Flows Provided by Financing Activities
Net cash provided by financing activities was $0.6 million for fiscal year 2025, compared to $0.1 million and $7.3 million for fiscal years 2024 and 2023, respectively. For the fiscal years 2023, net proceeds from the sale of our common stock under our “At-the-Market” offering program were $6.8 million, compared to no such sales during fiscal years 2025 and 2024. In fiscal years 2025, 2024, and 2023, the proceeds from the issuance of common stock under employee stock plans were $1.4 million, $1.8 million, and $2.6 million, respectively. In fiscal 2025, 2024 and 2023, cash used in shares repurchased for tax withholdings on vesting of restricted stock units was $0.8 million, $1.6 million and $2.0 million, respectively.
