PART I
Item 1. Business
OVERVIEW
Aehr Test Systems, Inc. (“Aehr Test,” “Aehr,” or “we”) was incorporated in the state of California on May 25, 1977 and is headquartered in Fremont, California. We are a leading provider of test solutions for testing, burning-in, and stabilizing semiconductor devices in wafer level, singulated die, and package level, and have installed thousands of systems worldwide. Mission critical applications are driving increased quality, reliability, safety, and security needs of semiconductors. The applications include artificial intelligence (“AI”), High Performance Compute (“HPC”) data centers, E-mobility (electric vehicles), electric vehicle charging infrastructure, solar and wind power, data and telecommunications infrastructure, and solid-state memory storage. The 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-PTM family of test and burn-in systems and FOX WaferPakTM 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 stabilize a wide range of devices such as leading-edge silicon carbide-based and gallium nitride 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 used in AI. 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 enables integrated circuits (“ICs”), manufacturers to perform test, burn-in, and stabilization of full wafers on the FOX-P systems. The FOX DiePak Carrier allows testing, burn-in, and stabilization 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. The introduction of the High Power FOX-XP in connection with the Sonoma Ultra high-power package level reliability/burn-in test solutions and Sonoma Ultra Automated Loader and Unloader enable Aehr the unique ability to deliver wafer level test and burn-in and package level burn-in for AI accelerators, GPUs, and HPC processors. The combination positions us well within the rapidly growing AI market as a turn-key provider of reliability and testing that span from engineering to high volume production. In combination with Sonoma, Tahoe and Echo package level burn-in systems, we provide a full range of solutions for semiconductor devices.
INDUSTRY BACKGROUND
Semiconductor manufacturing is a complex, multi-step process, and defects or weaknesses that may result in the failure of a semiconductor device may be introduced at any process step. Failures may occur immediately or at any time during the operating life of the device, sometimes after several months of normal use. Semiconductor manufacturers rely on testing and reliability screening to identify and eliminate defects that occur during the manufacturing process.

| Tab le of Contents |
Testing and reliability screenings involve multiple steps. The first set of tests is typically performed by semiconductor device manufacturers before the processed semiconductor wafer is cut into individual die, in order to avoid the cost of packaging defective die. This “wafer probe” testing can be performed on one or many die at a time, including testing the entire wafer at once. Most leading-edge microprocessors, microcontrollers, digital signal processors, memory ICs, sensors, power and optical devices (such as vertical-cavity surface-emitting lasers, or VCSELs) then undergo an extensive reliability screening and stress testing procedure known as burn-in or cycling, depending on the application. This can either be done at the wafer level, before the die are packaged, or at the package level, after the die are packaged. The burn-in process screens for early failures by operating the device at elevated voltages and temperatures, at up to 150 degrees Celsius (302 degrees Fahrenheit) or higher. Depending upon the application, the burn-in times can range anywhere from minutes to hours or even days. A typical burn-in system can process thousands of devices simultaneously. After burn-in, the devices undergo a final test process using automatic test equipment, or testers. For example, this cycling process screens silicon carbide semiconductor devices used in electric vehicle engine controller inverters and their corresponding on-board battery chargers for failure to meet current power loss and leakage specifications, as well as endurance requirements.
MARKETS
The Company’s semiconductor test and reliability qualification solutions address multiple test and burn-in markets including Artificial Intelligence devices for Large Language Models (“LLMs”) and Inference, Silicon Carbide (“SiC”) and Gallium Nitride (“GaN”) devices for power semiconductors, electric vehicles, electric vehicle charging infrastructure, solar and wind power, silicon photonics for data center infrastructure, Co-Package Optics (CPO) and worldwide 5G infrastructure, 2D/3D sensors for consumer electronics and automotive applications, and the data storage and memory markets.
Artificial Intelligence
The Artificial Intelligence and Inference processor market is experiencing a significant surge, driven by the increasing demand for machine learning and AI applications. Semiconductor companies are continuously innovating and releasing new AI chips to meet this demand. The production of AI processor wafers has seen substantial growth, with companies shipping millions of devices.
As the AI processor market grows, the Company expects the need for burn-in to become increasingly important. AI processors’ distinct architecture of die-to-die interdependency and increased memory size and use create a unique opportunity for the Company to apply enabling wafer level test and burn-in technology and package level burn-in for its customers and potential future customers. Subjecting the AI processors under stress to eliminate potential failures before they are deployed is crucial as they are often used in critical applications where failure can have significant consequences. Therefore, as the AI chip market continues to expand, the requirement for robust and efficient burn-in processes increases. These processes work to ensure the reliability and longevity of AI chips, thereby helping to contribute to the overall growth and success of the AI industry.
Silicon Photonics
The silicon photonics market is experiencing rapid growth in device deployment as data centers and 5G networks expand to meet surging bandwidth demand.
Growing adoption of integrated optical devices across data centers, data center interconnects, mobile devices, automotive systems, and wearable biosensors is driving significantly higher requirements for initial quality and long-term reliability — standards that rise with each new product generation. Silicon photonics integrated circuits are also expanding into optical chip-to-chip communication, with multiple companies announcing roadmaps for co-packaged photonics integrated with microprocessors, graphics processors, and chipsets for computing and artificial intelligence applications.
Silicon photonics devices are highly integrated silicon-based semiconductors in which non-silicon laser transmitters and receivers are bonded directly to a silicon chip containing the multiplexing, de-multiplexing, and other high-speed communication circuitry. This integration enables a smaller, lower-cost, more reliable alternative to traditional fiber optic transceivers used in data center and telecommunications infrastructure. Manufacturing these devices requires a critical step called stabilization, in which they are subjected to high temperatures and power to stabilize output. The Company's solution enables this burn-in process to be performed at the wafer level — before dicing and packaging — eliminating the need to build it into the transceiver's printed circuit board or other module-level infrastructure. This approach delivers both higher yields and significant cost savings.

Power Semiconductors (Silicon Carbide (“SiC”) and Gallium Nitride (“GaN”))
Silicon Carbide power semiconductors have emerged as the preferred technology for battery electric vehicle power conversion in on-board and off-board electric vehicle battery chargers, and the electric power conversion and control of the electric engines. These devices reduce power loss by as much as greater than 75% compared to power silicon alternatives like IGBT (Insulated-Gate Bipolar Transistor) devices, which has essentially changed the entire market dynamic. With the power efficiency advantages of SiC, the Company sees most, if not every electric vehicle automotive company moving to silicon carbide-based powertrain and charging systems in the near future.
The GaN market appears to be a potentially significant growth driver for our FOX systems and WaferPak full wafer contactors, particularly for automotive, photovoltaic and other industrial applications where burn-in appears to be critical for meeting the initial quality and reliability needs of those markets.
The Company’s FOX-P family of products are cost-effective solutions to help ensure the critical quality and reliability of devices in this market, where a single power semiconductor failure in a vehicle's drivetrain can lead to failure of the entire system.
Data Storage and Memory
The Company also views emerging developments in the data storage and memory markets as new opportunities for its systems, as these end markets and customers require devices with extremely high levels of quality and long-term reliability. One such opportunity for wafer-level burn-in is semiconductors used in solid state disk drives for data storage using NAND flash semiconductor memory devices. The NAND flash memory market performs 100% test and burn-in on devices used in mission-critical applications such as enterprise storage, and the Company sees this as an opportunity for its fully automated systems and WaferPaks.
Within Dynamic Random Access Memory (“DRAM”), the Company sees a particularly compelling opportunity in High Bandwidth Memory ("HBM"), the stacked memory architecture increasingly used alongside GPUs and AI accelerators to meet the extreme bandwidth demands of artificial intelligence and high-performance computing workloads. Because HBM stacks multiple DRAM die using through-silicon via interconnects, a single defective die can compromise an entire high-value stack after assembly, making upfront wafer-level test and burn-in especially valuable for detecting latent defects before stacking and packaging. As HBM adoption accelerates with the growth of AI infrastructure, the Company believes this represents a significant long-term growth opportunity for its wafer-level test and burn-in solutions.
Automotive Semiconductors
In addition, the rapid growth and increasing demand for reliability in automotive sensor technologies is a key market driver for the Company. These technologies include Advanced Driver Assistance Systems (“ADAS”) capabilities such as collision avoidance systems using laser, Light Detection and Ranging (“LIDAR”), and Radio Detection and Ranging (“RADAR”) or other sensing technologies. More and more new vehicles now include as standard capabilities collision avoidance systems that detect obstacles and monitor the vehicle’s surroundings to notify the driver of dangerous conditions and take evasive action. In addition to autonomous vehicles that require extremely high reliability of the devices in these systems, more and more vehicles around the world are embedding these systems and sensors into their everyday driving features. The Company sees the rising tide of the increasing number of embedded sensors and electrical and optical systems in vehicles as a key driver of the increasing market need for reliable semiconductors. This, in turn, is increasing the need for 100% production test and burn-in of devices to lower the infant mortality rate of devices and ensure that these devices and systems operate over the life of the vehicles.
PRODUCTS
The Company manufactures and markets full wafer contact test systems, test during burn-in systems, test fixtures and related accessories.
All of the Company’s systems are platform-based systems with a portfolio of current, voltage, digital and thermal capabilities, allowing them to be configured with optional features to meet customer requirements. Systems can be configured for use in production applications, where capacity, throughput and price are most important, or for reliability engineering and quality assurance applications, where performance and flexibility, such as extended temperature ranges, are essential.

| Tab le of Contents |
The Company’s product portfolio is platform-based systems with a modular configurable approach to enable a broad market approach while leveraging refined high-quality modules as building blocks. The platform-based system enables the optimized configuration for the market, application or specific customer requirement. Modules and configurability provide a range of current and voltage selections over a range of power and thermal capacities while enabling digital control for each unique device requirement. Implementing this approach along with our proprietary full wafer contactors and device interface carriers provides our customers with the ability to configure a system for engineering characterization and reliability qualification and high-volume production applications.
Wafer Level and Die Level Test and Burn-in Systems
Aehr’s FOX-XP test and burn-in platform allows for reliability screening tests to be completed on an entire wafer full of devices, testing all of them at once or multiple touchdowns, while also testing and monitoring every device for failures during the burn-in process to provide critical information on those devices. This is an enormously valuable capability, as it screens out devices that would otherwise fail after they are packaged into multi-die modules where the yield impact could be 10 times or even 100 times as costly.
The FOX-XP test and burn-in system, introduced in July 2016, is designed for devices in wafer, singulated die, and module form that require test and burn-in times typically measured in hours to days. The FOX-XP system can test and burn-in up to 18 wafers at a time. For high reliability applications, such as automotive, mobile devices, networking, telecommunications, sensors, power and solid-state devices, the FOX-XP system is a cost-effective solution for producing tested and burned-in die for use in multi-chip packages. Using Known-Good Die, or KGD, which are fully burned-in and tested die, in multi-chip/heterogeneous packages assures the reliability of the final product and lowers costs by increasing the yield of high-cost multi-chip packages. Wafer-level burn-in and test enables lower cost production of KGD for multi-chip modules, 3-D stacked packages and systems-in-a-package. The FOX-XP platform has been extended for burn-in and test of small multi-die modules by using DiePak Carriers. The DiePak Carrier with its multi-module sockets and high wattage dissipation capabilities has a capacity of hundreds of die or modules, much higher than the capacity of a traditional burn-in system with traditional single-device sockets and heat sinks.
The FOX-NP is a low-cost entry-level system to provide a configuration and price point for companies to initiate a new product introduction and production qualification, enabling an easier transition to the FOX-XP system for high volume production test. The FOX-NP system is 100% compatible with the FOX-XP system and is configurable with up to two slot assemblies per system compared to up to 18 slot assemblies in the FOX-XP system.
The FOX-CP is a low-cost single-wafer compact test and reliability verification solution for logic, memory, power and photonic devices. The FOX-CP reduces test cost by functionally testing wafers during reliability screening to identify failing logic, memory, power or photonic die before the die are integrated into their final package, and is optimal for test times ranging from minutes to a few hours or where multiple touchdowns are required to test the entire wafer. The FOX-CP includes an integrated prober which is equipped with optics for automatic pattern recognition so that the wafer is aligned properly for the testing process. It complements the capabilities of the FOX-XP and FOX-NP systems, which are optimal when the test time is measured in hours or days and the full wafer can be tested in a single touchdown.
One of the key components of the FOX systems is the patented WaferPak Contactor. The WaferPak Contactor contains a full-wafer single-touchdown probe card which is easily removable from the system. Traditional probe cards often are only able to contact a portion of the wafer, requiring multiple touchdowns to test the entire wafer. Traditional probe cards also require the use of a dedicated wafer prober handler for each wafer in order to press the wafer up to make contact with the probe card. The need for a wafer prober per wafer is a significant cost adder to the cost of testing a wafer, and also creates the need for significant clean room space to facilitate the footprint of a wafer prober per wafer. The unique design of the WaferPak as well as the FOX-XP and FOX-NP systems remove the need for a dedicated wafer prober per wafer, allowing for better utilization of clean room space. A single FOX-XP system with a set of WaferPak Contactors can test up to 18 wafers at a time in the same footprint as a single-wafer wafer prober and test system offered by Aehr’s competitors. The WaferPak Contactor is intended to accommodate a wide range of contactor technologies so that the contactor technology can evolve along with the changing requirements of the customer’s wafers. The WaferPak Contactors are custom designed for each device type, each of which has a typical lifetime of two to seven years, depending on the device life cycle. Therefore, multiple sets of WaferPak Contactors could be purchased over the life of a FOX system.
Another key component of the FOX-XP and FOX-NP systems is the patented DiePak Carrier. The DiePak Carrier, which is easily removable from the system, contains many multi-module or die sockets with very fine-pitch probes. Traditional sockets contact only a single device, requiring multiple large numbers of sockets and burn-in boards to test a production lot of devices. The unique design accommodates a wide range of socket sizes and densities so that the DiePak Carrier technology can evolve along with the changing requirements of the customer’s devices. The DiePak Carriers are custom designed for each device type, each of which has a typical lifetime of two to seven years, depending on the device life cycle. Therefore, multiple sets of DiePak Carriers could be purchased over the life of a FOX-XP or FOX-NP system.

Another key component of our FOX-XP and FOX-NP and test solution is the WaferPak Aligner. The WaferPak Aligner performs alignment of the customer’s wafer to the WaferPak Contactor so that the wafer can be tested and burned-in by the FOX-XP and FOX-NP systems. The Company offers an automated aligner for high volume production applications, which can support several FOX-XP or FOX-NP systems or can be connected to a FOX-XP resulting in a fully integrated automated test cell, and a manual aligner for low volume production or engineering applications. The latest generation Automated WaferPak Aligner supports industry standard Automated Material Handling System (“AMHS”), Automated Guided Vehicle (“AGV”), Overhead Hoist Transfer (“OHT”) and SEMI Equipment Communication Standard (“SECS”) and Generic Equipment Mode (“GEM”) Semi E84 factory integration enabling “Lights-out” fully automated wafer handling. Supporting a wide range of wafer sizes (e.g. 100/200/300mm) allows a broad range of customers to implement fully automated wafer level test and burn-in factories.
Similar to the WaferPak Aligner for WaferPak Contactors, the Company offers the DiePak Loader for DiePak Carriers. The DiePak Loader performs automatic loading of the customer’s modules to the DiePak Carrier so that the modules can be tested and burned-in by the FOX-XP and FOX-NP system. Typically, one DiePak Loader can support several FOX-XP or FOX-NP systems.
Net revenues of full wafer contact product lines, systems, WaferPak Contactors and services for fiscal 2026, 2025, and 2024 were $31.5 million, $39.2 million, and $64.6 million, respectively, and accounted for approximately 63%, 66%, and 98% of the Company’s net revenues in fiscal 2026, 2025, and 2024, respectively.
Package Level Test and Burn-in Systems
Aehr’s package level test and burn-in systems consist of several products serving multiple electrical, power, and thermal requirements to meet a wide variety of semiconductor reliability qualification and production screening and burn-in needs. Each of these products include several subsystems: pattern generation and test electronics, control software, network interface and environmental chamber. The test pattern generator allows duplication of most of the functional tests performed by a traditional tester. Pin electronics at each burn-in board (“BIB”) or Burn-in module (“BIM”) position are designed to provide accurate signals to the ICs being tested and detect whether a device is failing the test.
Lower power devices being tested up to 20-50 watts per device are placed on BIBs and loaded into environmental chambers which typically operate at temperatures from 25 degrees Celsius (77 degrees Fahrenheit) up to 175 degrees Celsius (347 degrees Fahrenheit). Using our optional chambers, our systems can produce temperatures as low as -55 degrees Celsius (-67 degrees Fahrenheit). A single BIB can hold up to several hundred ICs, and a production chamber holds up to 72 BIBs, resulting in thousands of memory or logic devices being tested in a single system.
For high-power applications, devices under test are placed on BIMs which are loaded into our power burn-in systems. Pin electronics and power supplies are dedicated to each individual device under test (“DUT”) and all resources are near the DUT to optimize signal integrity and accuracy. The temperature is controlled locally at DUT level and thermal control is liquid cooled.
Our product portfolio includes package level burn-in solutions for the full range of power and complexity of integrated circuits. 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 1600 or more watts. The Sonoma is available in its standard configuration, which supports up to 88 devices with independent test resources 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 installed globally at independent test and burn-in labs, as well as semiconductor manufacturers for high volume production.
Net revenues of package level product lines, systems and services for fiscal 2026, 2025, and 2024 were $18.5 million, $19.8 million, and $1.6 million, respectively, and accounted for approximately 37%, 34%, and 2% of the Company’s net revenues in fiscal 2026, 2025, and 2024 respectively.

CUSTOMERS
The Company markets and sells its products throughout the world to semiconductor manufacturers, semiconductor contract assemblers, electronics manufacturers and burn-in and test service companies.
Revenues from the Company’s five largest customers accounted for approximately 70%, 77%, and 93% of its net revenues in fiscal 2026, 2025, and 2024, respectively. During fiscal 2026, three customers accounted for approximately 26%, 14% and 11% of the Company’s net revenues. During fiscal 2025, two customers accounted for approximately 39% and 15% of the Company’s net revenues. During fiscal 2024, two customers accounted for approximately 67% and 17% of the Company’s net revenues. No other customers accounted for more than 10% of the Company’s net revenues for any of these periods. The Company expects that sales of its products to a limited number of customers will continue to account for a high percentage of net revenues for the foreseeable future. In addition, revenues from significant customers may fluctuate significantly from quarter to quarter. Such fluctuations may result in changes in the utilization of the Company’s facilities and resources. The loss of or reduction or delay in orders from a significant customer or a delay in collecting or failure to collect accounts receivable from a significant customer could materially and adversely affect the Company’s business, financial condition and operating results.
MARKETING, SALES AND CUSTOMER SUPPORT
The Company has sales and service operations in the United States, Germany, Japan, the Philippines and Taiwan, dedicated sales and service resources in China and South Korea, and has established a network of distributors and sales representatives in certain key parts of the world. See “Revenue Recognition” in Item 7 under “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for a further discussion of the Company’s relationship with distributors, and its effects on revenue recognition.
The Company’s customer service and support program includes system installation, system repair, applications engineering support, spare parts inventories, customer training and documentation. The Company has applications engineering and field service personnel located near and sometimes co-located at our customers and includes resources at the corporate headquarters in Fremont, California, at customer locations in Texas, at the Company’s subsidiaries in Germany, Japan and the Philippines, at its branch office in Taiwan, and also through third-party agreements in China and South Korea. The Company’s distributors provide applications and field service support in other parts of the world. The Company customarily provides a warranty on its products. The Company offers service contracts on its systems directly and through its subsidiaries, distributors and representatives. The Company believes that maintaining a close relationship with customers and providing them with ongoing engineering support improves customer satisfaction and will provide the Company with a competitive advantage in selling its products to the Company’s customers.
BACKLOG
At May 29, 2026, the Company’s backlog was $80.6 million compared with $15.2 million at May 30, 2025. The Company’s backlog consists of product orders for which confirmed purchase orders have been received and which are scheduled for shipment within 12 months. Due to the possibility of customer changes in delivery schedules or cancellations and potential delays in product shipments or development projects, the Company’s backlog as of a particular date may not be indicative of net revenues for any succeeding period.
RESEARCH AND PRODUCT DEVELOPMENT
The Company historically has devoted a significant portion of its financial resources to research and development programs and expects to continue to allocate significant resources to these efforts. For information regarding our research and development expenses during the last three fiscal years, see Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this Annual Report on Form 10-K.
The Company conducts ongoing research and development to design new products and to support and enhance existing product lines. Building upon the expertise gained in the development of its existing products, the Company has developed the FOX family of systems for performing test and burn-in of entire processed wafers, and burn-in of devices in singulated die and module form, including the FOX-NP and FOX-CP systems released during fiscal 2019, and the Automated WaferPak Aligner released during fiscal 2023 and the acquisition of the Sonoma, Tahoe and Echo platforms in fiscal 2025. The Company is developing enhancements to wafer level and package level burn-in products, and automation intended to improve the capability and performance for testing and burn-in of future generation devices and provide the flexibility in a wide variety of applications.

MANUFACTURING
The Company assembles its products from components and parts manufactured by others, including environmental chambers, power supplies, metal fabrications, printed circuit assemblies, ICs, burn-in sockets, high-density interconnects, wafer contactors and interconnect substrates. The Company’s strategy is to use in-house manufacturing only when necessary to protect a proprietary process or when a significant improvement in quality, cost or lead time can be achieved and relies on subcontractors to manufacture many of the components and subassemblies used in its products. Final assembly and testing are performed at the Company’s principal manufacturing facility located in Fremont, California. In addition, during fiscal 2026, the Company worked with a long time established subcontractor of the Company to do final integration and test of its Sonoma package level test and burn-in systems. During its fourth fiscal quarter, the Company signed off on the qualification of direct shipments of Sonoma systems to customers. This additional manufacturing capacity significantly increases the total manufacturing capacity of the Company.
COMPETITION
The semiconductor equipment industry is intensely competitive. Significant competitive factors in the semiconductor equipment market include price, technical capabilities, quality, flexibility, automation, cost of ownership, reliability, throughput, product availability and customer service. In each of the markets it serves, the Company faces competition from established competitors and potential new entrants, many of which have greater financial, engineering, manufacturing and marketing resources than the Company.
The Company expects its 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 the Company’s competitors or by new market entrants could cause a decline in sales or loss of market acceptance of the Company’s products. The Company has 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 the Company’s operating margins and results. The Company believes that to remain competitive it must invest significant financial resources in new product development and expand its customer service and support worldwide. There can be no assurance that the Company will be able to compete successfully in the future.
PROPRIETARY RIGHTS
The Company relies primarily on the technical and creative ability of its personnel, its proprietary software, and trade secrets and copyright protection, rather than on patents, to maintain its competitive position. The Company’s proprietary software is copyrighted and licensed to the Company’s customers. As of May 29, 2026, the Company held 125 active patents in the United States, Singapore, China, Germany, Ireland, Italy, Netherlands, United Kingdom, Japan, South Korea, Malaysia, Philippines, Taiwan and other countries, with expiration date ranges from 2028 to 2045, and had over 100 additional United States patent applications and foreign patent applications pending.
The Company’s ability to compete successfully is dependent in part upon its ability to protect its proprietary technology and information. Although the Company attempts to protect its proprietary technology through patents, copyrights, trade secrets and other measures, there can be no assurance that these measures will be adequate or that competitors will not be able to develop similar technology independently. Further, there can be no assurance that claims allowed on any patent issued to the Company will be sufficiently broad to protect the Company’s technology, that any patent will be issued to the Company from any pending application or that foreign intellectual property laws will protect the Company’s intellectual property. Litigation may be necessary to enforce or determine the validity and scope of the Company’s proprietary rights, and there can be no assurance that the Company’s intellectual property rights, if challenged, will be upheld as valid. Any such litigation could result in substantial costs and diversion of resources and could have a material adverse effect on the Company’s business, financial condition and operating results, regardless of the outcome of the litigation. In addition, there can be no assurance that any of the patents issued to the Company will not be challenged, invalidated or circumvented or that the rights granted thereunder will provide competitive advantages to the Company. Also, there can be no assurance that the Company will have the financial resources to defend its patents from infringement or claims of invalidity. For a description of the infringement proceedings in China seeking to protect two of the Company’s patents, see Note 9, “Commitments and Contingencies” in the Notes to Consolidated Financial Statements.

As of May 29, 2026, there were no pending claims against the Company regarding infringement of any patents or other intellectual property rights of others. However, the Company may, from time to time, receive communications from third parties asserting intellectual property claims against the Company. Such claims could include assertions that the Company’s products infringe, or may infringe, the proprietary rights of third parties, requests for indemnification against such infringement or suggest the Company may be interested in acquiring a license from such third parties. There can be no assurance that any such claim made in the future will not result in litigation, which could involve significant expense to the Company, and, if the Company is required or deems it appropriate to obtain a license relating to one or more products or technologies, there can be no assurance that the Company would be able to do so on commercially reasonable terms, or at all.
ENVIRONMENTAL, SOCIAL AND GOVERNANCE (ESG)
Environmental
The Company focuses on clean technology such as the electrical vehicle (“EV”) and power semiconductors market. EV and power semiconductor revenues accounted for 17%, 41%, and 92% of total revenues in fiscal 2026, 2025, and 2024, respectively. We engineer our products to be more energy efficient by using more efficient electrical designs and thermally efficient cooling architectures using conductive heat transfer versus convection air cooled methods. Our technology and architectural design allow our products to take up to as little as only 5% of the test floor space compared to competitor’s products.
The Company improved its facilities by replacing existing air conditioners and heat exchangers with higher efficiency units that draw less power and produce less wasted energy. Our headquarters facility upgrades include moving to high efficiency lighting, modernizing our electrical power and cooling infrastructure.
Social
The Company reviews hiring and turnover quarterly and performs annual salary reviews, using independent third-party data, to ensure competitive compensation practices. The Company conducts annual employee surveys to evaluate employee satisfaction. Glassdoor shows the Company at a 4.3 out of 5 rating as a great place to work.
The Company provides variable compensation on top of base salary for all employees including an employee profit sharing plan. The Company also provides equity awards including stock options, restricted stock units (“RSUs”), and participation in an employee stock purchase plan for regular full-time (“RFT”) employees, located in the U.S. The Company is restricted from issuing stock options or RSUs to non-U.S. employees in certain countries due to local regulations. For those employees who are unable to participate in the Company’s equity incentive plan, the Company maintains a stock appreciation bonus program to provide compensation linked to the Company’s stock price during a predetermined period. The Company also provides a 401(k) plan for U.S. employees, which includes an employer discretionary matching contribution to eligible compensation.
The Company provides recurring training in compliance with State of California regulations including sexual harassment, prevention of violence in the workplace, and safety training. The Company promotes employee engagement through corporate events or activities on a regular basis.
The Company provides health care coverage for all RFT employees, life insurance, continuing education assistance, and reimbursement of U.S. employee health club membership. The Company ensures compliance with International Organization for Standardization (“ISO”) certification and maintains safety training.
Governance
As the Company pursues future Board recruitment efforts, the Nominating Committee will continue to seek candidates who can contribute a wide range of views and perspectives to the Board. This includes seeking out individuals with a variety of perspectives informed by personal and professional experiences.
All employees and Board members sign a Code of Conduct and Ethics Policy, and Insider Trading Policy upon hire. All employees are provided with the employee handbook which addresses Sexual Harassment, Confidentiality, and Electronic Use Policy among others. Each of the Company’s directors and officers completes a Director and Officer Questionnaire to identify conflicts of interest or areas of concern.

HUMAN CAPITAL RESOURCES
As of May 29, 2026, the Company, including its foreign subsidiaries and one branch office, employed 138 persons collectively, on a regular full-time basis, of whom 43 were engaged in research, development and related engineering, 46 were engaged in manufacturing, 34 were engaged in marketing, sales and customer support and 15 were engaged in general administration, finance and IT functions. In addition, the Company, from time to time, may employ a few contractors, temporary, and part-time employees, particularly to perform customer support and manufacturing.
The Company’s employees are dispersed across principal offices in the United States, Germany, Taiwan, and the Philippines. In addition, our service and support organization has employees located worldwide, at or near customer facilities, to provide timely customer response. As of May 29, 2026 regular full-time employees were located in the following geographic areas: 103 in United States, 28 in the Philippines, six in Taiwan, and one in Germany.
The Company’s success is in part dependent on its ability to attract and retain highly skilled workers, who are in high demand. None of the Company’s employees are represented by a union and the Company has never experienced a work stoppage due to strike. The Company’s management considers its relations with its employees to be good. The Company regularly evaluates its ability to attract and retain its employees. The Company has had relatively low turnover rates within its workforce, with 53% of its regular full-time workforce being with the Company for 5 years or more.
The Company believes that the investments we make in driving a strong, values-based culture and supporting its employees through programs, development, and competitive pay enhances its organizational capability. The Company’s management reviews retention and turnover data, employee communications, performance review status, and compensation and benefits to identify potential issues or opportunities for improvement on a quarterly basis. The Company periodically performs employee surveys to monitor employee satisfaction, and the Company follows up with an action planning process to actively respond to employee feedback.

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 70%, 77%, and 93% of our net sales in fiscal 2026, 2025, and 2024, respectively. During fiscal 2026, three customers accounted for approximately 26%, 14% and 11% of our net sales. During fiscal 2025, two customers accounted for approximately 39% and 15% of our net sales. During fiscal 2024, two customers accounted for approximately 67% and 17% of our net sales. No other customers accounted for more than 10% of our net sales for any of these periods.
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, since the second half of fiscal 2025, global tariff announcements had 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.
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 is 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.
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 package level 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. We expect that our DiePak products for burning-in and testing multiple singulated die and small modules face significant competition. We believe 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.

| Tab le of Contents |
Additionally, the semiconductor industry has experienced significant consolidation over the past several years, and such consolidation may further increase competitive factors within the industry. We also 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 package level 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 related to components and subsystems supplied to us by third parties, which in certain cases has limited our ability to address such issues promptly. This process in the past required and in the future is likely to require us to incur unreimbursed 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.
| 14 |
| Tab le of Contents |
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 breaches, phishing schemes, and other malicious software programs or cyberattacks. Such 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, reviewed with our Board of Directors on a periodic basis, 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.
| 15 |
| Tab le 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 purported claims, 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 exceed 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 and into our products and services. 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 supply chain, trade policy, and foreign sourcing risks that could adversely affect our business.
We purchase components, sub-assemblies, and chambers from suppliers outside the United States. Our reliance on global suppliers exposes us to risks associated with international sourcing, including supply chain disruptions, rising costs due to inflationary pressures, foreign currency fluctuations, and changes in trade or regulatory policies. 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, currency fluctuations, or protectionist policies could have a material adverse effect on our business, financial condition or results of operations.
Changes in U.S. tariff policies, retaliatory trade measures taken by other countries and resulting trade wars may have a material adverse impact on our results of operations.
Changes in U.S. tariff policy, import restrictions, export controls, sanctions, retaliatory trade measures, and broader trade disputes have adversely affected, and may continue to adversely affect, our business, financial condition, and results of operations. Although certain tariffs previously imposed by the United States under the International Emergency Economic Powers Act were invalidated by the U.S. Supreme Court in February 2026 and are no longer being collected, other tariffs and trade restrictions remain in effect or may be imposed, modified, expanded, or reinstated under other legal authorities.
These measures have increased, and may continue to increase, our cost of revenues and operating expenses by raising the cost of imported raw materials, components, equipment, and other inputs used in our business. Trade restrictions and tariffs imposed by the United States or by other countries may also reduce demand for our products in affected regions, cause our customers to delay, cancel, or reduce orders, increase supply chain complexity, require changes in sourcing strategies, or otherwise disrupt our operations and capital planning. In addition, uncertainty regarding the scope, timing, duration, and enforcement of trade measures may make it more difficult for us, our customers, and our suppliers to plan and execute business activities and investments.
Our efforts to address these risks, such as through operational adjustments and pricing strategies, may not be successful. Such efforts may need time to take effect and may have an adverse impact on our results of operations.
| 17 |
| Tab le of Contents |
Any continuation, expansion, modification, or reinstatement of tariffs or other trade restrictions, any additional retaliatory measures by other countries, or any escalation of trade disputes could materially and adversely affect our business, financial condition, and 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 59%, 70%, and 95% of our net sales in fiscal 2026, 2025, and 2024, 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, and a service organization in the Philippines, as well as direct support through third-party agreements in China and South Korea. 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. Geopolitical tensions involving the United States, China and Taiwan, or changes in U.S., Chinese, Taiwanese or other foreign trade policies, tariffs, export controls, sanctions, technology-transfer restrictions or diplomatic relations, could also adversely affect our ability to sell products in certain foreign markets, support customers, obtain materials or components, or compete effectively. In addition, we are subject to other risks associated with doing business internationally, including longer receivable collection periods and greater difficulty 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.
Our net sales 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, the political climate in China and Taiwan, and the conflicts in the Middle East 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 ongoing 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, the Middle East 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.

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 sole-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 sole-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.
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 us 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.

| Tab le of Contents |
There are no pending claims against 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 claims against 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 29, 2026, the price of our common stock has ranged from $6.27 to $112.00. 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.
We have been, and may in the future be, subject to securities class action lawsuits, shareholder derivative actions and other litigation or regulatory proceedings. Such matters may arise from, among other things, our public disclosures, financial results or guidance, stock price volatility, business transactions, alleged breaches of fiduciary duty or other corporate actions.
Defending against 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 motivate 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. In addition, maintaining effective internal control over financial reporting and complying with the requirements of Section 404 of the Sarbanes-Oxley Act require significant management time, attention, and financial resources. Compliance with these requirements may increase our operating costs, require the hiring of additional personnel or external advisors, and divert management's attention from other business priorities.
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 criminal penalties 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.

ITEM 1C. Cybersecurity
Cybersecurity Risk Management and Strategy
We have established processes for assessing, identifying, and managing material risk from cybersecurity threats, and have integrated these processes into our overall risk management systems and processes. To prevent, detect and respond to information security threats, we maintain a cyber risk management program that employs Cyber Security Framework (“CSF”) in accordance with the National Institute of Standards and Technology (“NIST”) security framework. CSF is a set of voluntary guidelines that help organizations assess and improve their cybersecurity posture by implementing processes for identifying and mitigating risk, and detecting, responding to and recovering from cyberattacks.
We conduct periodic risk assessments to identify cybersecurity threats, as well as assessments in the event of a material change in our business practices that may affect information systems that are vulnerable to such cybersecurity threats. These risk assessments include identification of reasonably foreseeable internal and external risks, the likelihood and potential damage that could result from such risks, and the sufficiency of existing policies, procedures, systems, and safeguards in place to manage such risks. Following these risk assessments, we re-design, implement, and maintain reasonable safeguards to minimize identified risks; reasonably address any identified gaps in existing safeguards; and regularly monitor the effectiveness of our safeguards.
Our Security Awareness Program includes training that reinforces our information technology risk and security management policies, standards and practices, as well as the expectation that employees comply with these policies. The Security Awareness Program engages personnel through training on how to identify potential cybersecurity risks and protect the Company’s resources and information. This training is mandatory for all employees on a periodic basis, and it is supplemented by Company-wide testing initiatives.
We have deployed approved enterprise AI platforms, including Claude for engineering teams and Copilot for other personnel, and are actively working to formalize policies, guidance, and employee training around the acceptable use of AI tools.
Our processes also address cybersecurity threat risks associated with our use of third-party service providers, including our suppliers or who have access to our systems. In addition, cybersecurity considerations affect the selection and oversight of our third-party service providers. We perform diligence on third parties that have access to our systems, data or facilities that house such systems or data, and continually monitor cybersecurity threat risks identified through such diligence.
While we have not, as of the date of this Report, experienced any material cybersecurity incidents that materially affected us, including our operations, business strategy, results of operations, or financial condition, we face risks from cybersecurity threats that, if realized, are reasonably likely to materially affect our business, financial condition, and results of operations. See “Risk Factors – We are exposed to cybersecurity threats or incidents.”
Cybersecurity Governance
One of the key functions of our Board of Directors is informed oversight of our risk management processes, including risks from cybersecurity threats. Our Board of Directors is responsible for monitoring and assessing strategic risk exposure, and our executive officers are responsible for the day-to-day management of the material risks we face. Our Board of Directors administers its cybersecurity risk oversight function directly as a whole, as well as through the Audit Committee of the Board of Directors (the “Audit Committee”). The Audit Committee has primary responsibility for oversight of information security risks, including fraud, vendor, data protection and privacy, business continuity and resilience, and cybersecurity risks, and provides regular updates to the Board of Directors on such matters. The Audit Committee receives regular reports from our Chief Operating Officer on, among other things, the Company’s cyber risks and threats, the status of projects to strengthen the Company’s information security systems, assessments of the Company’s security program and the emerging threat landscape. Information security risk is a significant oversight focus area for the Audit Committee, as well as the entire Board of Directors. Over the course of fiscal year 2026, the Audit Committee received four separate cybersecurity briefings from our Chief Operating Officer.
Our Chief Operating Officer is primarily responsible for assessing and managing our material risks from cybersecurity threats. Our Chief Operating Officer leads a team responsible for enterprise-wide cybersecurity strategy, policy, standards, architecture and processes. The team has extensive experience and background in information technology, cybersecurity, enterprise strategy, risk management. Additionally, our Chief Operating Officer chairs our Cybersecurity Incident Response Team, which is responsible for prevention, identification, containment, eradication and remediation of cybersecurity incidents. He consults with experts in enterprise security and risk management to ensure our intellectual property and devices are protected. While we have not experienced a material information security (cybersecurity) incident, we maintain an information security (cybersecurity) risk insurance policy as a matter of good practice.

Item 2. Properties
The Company’s principal administrative and production facilities are located in Fremont, California, in a 51,289 square foot building. The Company’s lease was renewed in December 2022 and expires in September 2030 with an option to extend the lease for another five years. In April 2025, it became reasonably certain that the Company would exercise the five-year lease extension option due to the remodeling of the Fremont office. The Company leases a 492 square foot sales and support office in Utting, Germany. The lease, which began February 1, 1992 and contains an automatic twelve months renewal, at rates to be determined, if no notice is given prior to six months from expiration. On November 18, 2020, the Company established a wholly owned subsidiary, Aehr Test Systems Philippines Inc., which has been in full operation since March 2021. The Company currently leases a facility in Philippines located in a 6,458 square foot building in Clark Freeport Zone, Pampanga. The lease, amended in 2023, began November 1, 2023 and expires on June 30, 2029 with an option to renew for another three or five years at the prevailing market rate. Following the acquisition of Incal, the Company inherited Incal’s office in Fremont, California, which it subsequently vacated in May 2025 after relocating employees to its principal facilities in Fremont, to consolidate the Company’s California operations. In November 2025, the Company entered into a lease termination agreement with the landlord and was released from its remaining lease obligation. The Company periodically evaluates its global operations and facilities to bring its capacity in line with demand and to provide cost-effective services for its customers. In prior years, through this process, the Company has moved from certain facilities that exceeded the capacity required to satisfy its needs. The Company believes that its existing facilities in Fremont, California are adequate to meet its current and reasonably foreseeable requirements. The Company regularly evaluates its expected future facilities requirements and believes that alternate facilities would be available if needed.
Item 3. Legal Proceedings
From time to time, we are subject to various claims and legal proceedings that arise in the ordinary course of business. We accrue for losses related to litigation when a potential loss is probable and the loss can be reasonably estimated. For additional information regarding legal proceedings, refer to Note 9 – Commitments and Contingencies in the Notes to Consolidated Financial Statements.

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 level, and has installed thousands of systems worldwide. Decarbonization, generative AI and digitalization are 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 stabilize a wide range of devices such as leading-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 enables Integrated Circuit manufacturers to perform test, burn-in, and stabilization of full wafers on the FOX-P systems. The FOX DiePak Carrier allows testing, burning in, and stabilization 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.
Following the acquisition of Incal, our product portfolio further expanded to include package level 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 or more. 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, Sonoma systems, Tahoe systems, Echo 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.
Our operating results and cash flows can vary significantly from period to period due to the timing, volume, and mix of customer orders, particularly because a substantial portion of our revenue is derived from a relatively small number of high-value systems sales. As a result, the number, type, and selling price of systems sold in a given period can materially affect revenue, gross margin, earnings, and operating cash flow.
Demand for our products is influenced by conditions in the semiconductor industry and in the end markets served by our customers, including demand related to generative AI, silicon photonics and power semiconductors including silicon carbide and gallium nitride. During fiscal 2025 and fiscal 2026, our operating performance was negatively affected by continued softness in demand in electric vehicle power semiconductors. Changes in customer investment cycles, order timing, and the pace of adoption of new technologies may continue to affect our results in future periods.
In addition, our results of operations have been affected by changes in revenue mix across systems, contactors, and services, as well as by the integration and contribution of the acquired business. Because these factors can affect revenue levels, gross margins, operating expenses, and working capital differently from period to period, past performance may not necessarily be indicative of future results. Our liquidity and cash flows may also be affected by the timing of large system shipments, investments in inventory and working capital, capital expenditures, acquisition-related cash uses, and investments in product development and market expansion.

Recent changes in U.S. trade and tariff policies, including potential modifications to existing tariffs and the outcome of ongoing regulatory, administrative, or legal developments, may affect the cost of our imported goods, our supply chain, and, accordingly, our gross margins and operating results. The scope, timing, and ultimate impact of these developments remain uncertain, and we continue to evaluate their potential effects on our business, financial condition, and results of operations.
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.
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 ratably over time as the customer simultaneously receives the benefit of the services over the contractual period, which is 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.
| 26 |
| Tab le of Contents |
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 recognize deferred tax assets (“DTAs”) for deductible temporary differences, net operating loss carryforwards, and tax credit carryforwards to the extent we conclude it is more likely than not that such DTAs will be realized. Our DTAs relate solely to U.S. federal and state income taxes. At each reporting date, we evaluate the realizability of our DTAs and record a valuation allowance when, based on all available evidence, we conclude that it is not more likely than not that some portion or all of our DTAs will be realized.
This assessment requires significant judgment because it involves weighing both positive and negative evidence, with the most objective evidence generally carrying the greatest weight. In making this determination, we consider, among other factors: (i) recent operating results and cumulative pretax income (loss) in the United States; (ii) the duration and severity of any recent losses; (iii) projections of future taxable income based on our operating plans, including expected revenues, margins and cost structure; (iv) the availability and feasibility of tax planning strategies; and (v) the expected utilization periods and limitations applicable to carryforwards.
During fiscal 2024, we released a valuation allowance of $21.9 million after concluding that it was more likely than not that our U.S. DTAs would be realized. Although we incurred pretax losses in fiscal 2025 and fiscal 2026, we concluded as of May 29, 2026 that a valuation allowance against our U.S. DTAs was not required. In reaching this conclusion, we placed significant weight on positive evidence supporting future taxable income, including our expectation of a return to profitability in fiscal 2027, projected improvement in our cumulative pretax income position by fiscal 2027, and revenue projections supported by substantial backlog and visibility into near-term customer demand.
If actual results differ from our current estimates, if assumptions underlying our forecast of future taxable income change, or if negative evidence ultimately outweighs positive evidence, we may be required to record an additional valuation allowance or adjust an existing valuation allowance. Any such change could have a material impact on our income tax provision and our results of operations in the period of the change.
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 impairment loss 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 years ended May 29, 2026 and May 30, 2025.

Impairment of Long-Lived Assets
We monitor the carrying value of long-lived assets for potential impairment 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 29, 2026, the Company did not record any impairment of long-lived assets. 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.

Revenue decreased by $9.0 million in fiscal year 2026 compared to fiscal year 2025, primarily due to a $19.9 million decrease in wafer-level contactor revenue driven by significantly lower shipments, reflecting continued softness in demand related to electric vehicles. This decrease was partially offset by a $10.4 million increase in wafer-level burn-in systems revenue, primarily from customers in the silicon photonics market. Package-level burn-in products and service revenue remained relatively flat year over year.
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-level 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.

On a geographic basis, revenues represent products that were shipped to or services that were performed at our customer locations. For fiscal year 2026, revenue decreased in Asia primarily due to the ongoing softness in demand for electric vehicles. This decrease was partially offset by higher revenue in the United States, primarily attributable to increased demand in the silicon photonics market, and higher revenue in Europe and the Middle East, also primarily attributable to increased demand in the silicon photonics market.
For fiscal year 2025, revenue declined in Asia primarily due to 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.

Gross profit decreased by $6.3 million in fiscal year 2026 compared to fiscal year 2025, primarily due to lower revenue levels. Gross margin decreased by 5.3 percentage points primarily due to higher assembly and warranty costs, increased freight expenses, and higher tariffs on imported parts following the government policy changes.
Gross profit decreased by $8.6 million in fiscal year 2025 compared to fiscal year 2024. Gross margin decreased by 8.5 percentage points primarily due to the amortization of certain acquired intangible assets, the acquisition related fair value adjustment to inventory, an inventory variance charge, lower system shipments leading to reduced manufacturing efficiencies, and a change in product mix.

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 $2.2 million in fiscal year 2026 over fiscal year 2025 primarily driven by $1.6 million of higher employment-related costs, including stock-based compensation, resulting from increased headcount, and $1.1 million of higher allocated office expenses. These increases were partially offset by the $0.7 million of one-time severance benefits incurred in the prior year period following the death of an executive officer.
Research and development expenses increased by $1.7 million in fiscal year 2025 over fiscal year 2024 primarily due to $0.7 million in severance benefits incurred following the death of an executive officer, $0.9 million of higher employment related costs, including stock-based compensation expense, resulting from growth in engineering headcount, and $0.3 million of additional research and development expenses from the newly acquired Incal business. The increase was partially offset by $0.4 million of lower non-recurring engineering service charges.

Income tax benefit was $4.6 million in fiscal year 2026, primarily driven by operating losses in the United States and excess tax benefits from stock-based compensation.
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. 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 $116.5 million as of May 29, 2026, compared to $26.5 million as of May 30, 2025. We believe that our existing cash resources and anticipated funds generated from operations will satisfy our cash requirements to fund our operating activities, capital expenditures and other obligations for the next twelve months.

Net Cash Flows Provided by (Used in) Operating Activities
Net cash used in operating activities decreased by $4.1 million in fiscal year 2026 compared to fiscal year 2025. The decrease was primarily driven by higher customer deposits related to new bookings, a smaller increase in prepayments to vendors, lower cash outflows for inventory purchases and vendor payments, and higher stock-based compensation expense. These favorable changes were partially offset by a higher loss before income tax benefit.
Net cash 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.
Net Cash Flows Provided by (Used in) Investing Activities
Net cash used in investing activities decreased by $12.2 million in fiscal year 2026 compared to fiscal year 2025. The decrease was primarily due to the $11.1 million payment to acquire Incal during fiscal year 2025, compared to a $1.8 million escrow release related to the acquisition during fiscal year 2026. In addition, capital expenditure decreased by $2.9 million, primarily related to office renovation expenditures incurred during fiscal year 2025.
Net cash used in investing activities was $16.1 million for fiscal year 2025 compared to net cash provided by investing activities of $17.3 million for 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 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 fiscal year 2025.

Net Cash Flows Provided by Financing Activities
Net cash provided by financing activities was $97.2 million in fiscal year 2026, compared to $0.6 million in fiscal year 2025, and $0.1 million in fiscal years 2024, primarily driven by net proceeds of $97.4 million from the issuance of common stock under the Company’s ATM offering program. In fiscal years 2026, 2025, and 2024, proceeds from the issuance of common stock under employee stock plans were $2.2 million, $1.4 million, and $1.8 million, respectively. In fiscal 2026, 2025, and 2024 cash used in shares repurchased for tax withholdings on vesting of restricted stock units was $2.4 million, $0.8 million, and $1.6 million, respectively.

Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of Aehr Test Systems and its subsidiaries (the “Company”) as of May 29, 2026 and May 30, 2025, the related consolidated statements of operations, comprehensive income (loss), shareholders’ equity, and cash flows for each of the three years in the period ended May 29, 2026, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of May 29, 2026 and May 30, 2025, and the results of its operations and its cash flows for each of the three years in the period ended May 29, 2026, in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.
Inventory Valuation – Adjustments for Excess or Obsolete Inventory
The Company’s consolidated inventories balance was $41.4 million as of May 29, 2026. As described in Note 1 to the consolidated financial statements, the Company’s inventory is stated at the lower of cost, which is determined on a standard cost basis on a first-in, first-out method, or net realizable value. The Company evaluates the net realizable value by considering obsolescence, excessive levels of inventory, deterioration and other factors. Adjustments to reduce the cost of inventory to its net realizable value, if required, are made for estimated excess, obsolescence or impaired inventory. If actual demand were to be substantially lower than estimated, there could be a significant adverse impact on the carrying value of the inventory and results of operations.
The principal considerations for our determination that performing procedures relating to adjustments for excess or obsolete inventory is a critical audit matter are the significant amount of judgement by management in developing the assumptions of the forecasted product demand, which in turn led to significant auditor judgement, subjectivity, and effort in performing audit procedures and evaluating audit evidence relating to the forecasted product demand. Additionally, for certain new sales channels there may be limited historical data with which to evaluate forecasts.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included, among others, testing management’s process for developing the estimate of the adjustments for excess or obsolete inventory, testing the completeness and accuracy of the underlying data used in the estimate, and evaluating management’s assumptions of forecasted product demand. Evaluating management’s demand forecast for reasonableness involved considering historical sales of its products, comparing prior period estimates to actual results of the same period, and determining whether the demand forecast used was consistent with evidence obtained in other areas of the audit.

We have served as the Company’s auditor since 2005.

AEHR TEST SYSTEMS
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
Organization
Aehr Test Systems (the “Company”) was incorporated in California in May 1977 and primarily designs, engineers and manufactures test and burn-in equipment used in the semiconductor industry. The Company’s principal products are the FOX-XP, FOX-NP, and FOX-CP wafer contact parallel test and burn-in systems; the Sonoma, Tahoe and Echo package-level burn-in products; the WaferPak full wafer contactor; the DiePak Carrier; the WaferPak Aligner; the DiePak Autoloader; and test fixtures.
Principles of Consolidation
The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated.
Change in Fiscal Year
On April 2, 2026, the Company’s board of directors approved a change in the Company’s fiscal year-end from the 52- or 53-week period ending on the Friday nearest May 31 to the 52- or 53-week period ending on the Friday nearest June 30. The change will be effective beginning in fiscal year 2027, which begins on June 27, 2026 and ends on June 25, 2027.
Foreign Currency Translation and Transactions
Assets and liabilities of the Company’s foreign subsidiaries are translated into U.S. Dollars from their functional currencies using the exchange rate in effect at the balance sheet date. Additionally, revenues and expenses are translated using exchange rates approximating average rates prevailing during the fiscal year. Translation adjustments that arise from translating their financial statements from their local currencies to U.S. Dollar are accumulated and reflected as a separate component of shareholders’ equity.
Transaction gains and losses that arise from exchange rate changes denominated in currencies other than the local currency are included in the consolidated statements of operations as incurred.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates in the Company’s consolidated financial statements include revenue recognition, inventory valuation, business combination, impairment of goodwill and long-lived assets, and accounting for income taxes.
Cash and Cash Equivalents
Cash equivalents consist of money market instruments purchased with an original maturity of three months or less. These investments are reported at fair value.
Accounts Receivable and Allowance for Credit Losses
Accounts receivable are derived from the sale of products throughout the world to semiconductor manufacturers, semiconductor contract assemblers, electronics manufacturers and burn-in and test service companies. Accounts receivable are recorded at the invoiced amount and are not interest bearing.

The Company maintains an allowance for credit losses for expected uncollectible accounts receivable and assess collectibility by reviewing accounts receivable on a collective basis where similar risk characteristics exist and on an individual basis when specific customers with known disputes or collectibility issues are identified. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Changes in circumstances, such as an unexpected material adverse change in a major customer’s ability to meet its financial obligation to the Company, may require the Company to further adjust its estimates of the recoverability of accounts receivable. The credit losses recognized on accounts receivable during the years ended May 29, 2026, May 30, 2025 and May 31, 2024, were not significant and management has determined that no allowance for credit losses was required as of May 29, 2026 and May 30, 2025.
Concentration of Credit Risk
Financial instruments which subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. The Company’s cash and cash equivalents are generally deposited with major financial institutions in the United States, Philippines, Germany and Taiwan. The Company invests its excess cash in money market funds. The Company’s cash and investment balances held at banks and brokerage firms may at time exceed federally insured levels. The Company has not experienced any material losses on its money market funds or short-term cash deposits.
The Company performs credit evaluations of its customers’ financial condition and generally requires no collateral. The Company had revenues from individual customers in excess of 10% of total revenues as follows:

Inventories
Inventories include material, labor and overhead, and are stated at the lower of cost or net realizable value, with cost determined on a first-in, first-out (FIFO) basis. Net realizable value is the estimated selling prices in the ordinary course of business, less costs of completion, disposal and transportation. Provisions for excess, obsolete and unusable inventories are made after management’s evaluation of future demand and market conditions. If actual future demand or market conditions become less favorable than those projected by management, additional adjustment for excess or obsolete inventory may be required, and would be reflected in cost of revenue in the period the revision is made.

| Table of Contents |
Property and Equipment
Property and equipment are stated at cost less accumulated depreciation and amortization. Major improvements are capitalized, while repairs and maintenance are expensed as incurred. Leasehold improvements are amortized over the lesser of their estimated useful lives or the term of the related lease. Furniture and fixtures, machinery and equipment, and test equipment are depreciated on a straight-line basis over their estimated useful lives. The ranges of estimated useful lives are generally as follows:
Furniture and fixtures | |
Machinery and equipment | |
Test equipment |
Business Combination
The Company recognizes identifiable assets acquired and liabilities assumed at their acquisition date fair values. Goodwill is measured as the excess of the consideration transferred over the fair value of assets acquired and liabilities assumed on the acquisition date. While the Company uses its best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed, these estimates are inherently uncertain and subject to refinement. Key estimates and assumptions in valuing certain of the intangible assets and goodwill the Company has acquired include, but are not limited to, expected future cash flows from acquired developed technology, customer relationships, and trade names. Unanticipated events and circumstances could impact the accuracy or validity of such assumptions, estimates or actual results.
The authoritative guidance allows a measurement period of the purchase price allocation that ends when the entity has obtained all relevant information about facts that existed at the acquisition date, and that cannot exceed one year from the date of acquisition. As a result, during the measurement period, the Company may record adjustments to the fair values of assets acquired and liabilities assumed, with the corresponding offset to goodwill to the extent that it identifies adjustments to the preliminary purchase price allocation. Upon conclusion of the measurement period or final determination of the values of the assets acquired and liabilities assumed, whichever comes first, any subsequent adjustments will be recorded in the consolidated statements of operations.
Goodwill
Goodwill represents the excess of the total purchase price over the fair value of net identifiable assets acquired in a business combination. The Company assesses goodwill for impairment annually during each fourth fiscal quarter or whenever events or changes in circumstances indicate the carrying value may not be fully recoverable. In the valuation of goodwill, management estimates future cash flows to be derived from the Company’s business. If these estimates or their related assumptions change in the future, the Company may be required to record an impairment. Management 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. Management 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 impairment loss 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.
Definite-Lived Intangible Assets
The Company performs valuations of assets acquired and liabilities assumed on the acquisition accounted for as a business combination and allocates the purchase price of the acquired business to the identifiable net tangible and intangible assets. The Company determines the appropriate useful life by performing an analysis of expected cash flows based on historical experience of the acquired businesses. Intangible assets are amortized over their estimated useful lives using the straight-line method which approximates the pattern of consumption of economic benefits.
Impairment of Long-Lived Assets
The Company evaluates long-lived assets, including property and equipment and intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets held and used is measured by a comparison of the carrying amount of an asset or an asset group to estimated undiscounted future net cash flows expected to be generated by the asset or asset group. If such evaluation indicates that the carrying amount of the asset or the asset group is not recoverable, any impairment loss would be equal to the amount the carrying value exceeds the fair value.

Warranty Reserves
The Company provides for the estimated cost of product warranties at the time revenues are recognized on the products shipped. While the Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its component suppliers, the Company’s warranty obligation is affected by product failure rates, material usage and service delivery costs incurred in correcting a product failure. Should actual product failure rates, material usage or service delivery costs differ from the Company’s estimates, revisions to the estimated warranty liability would be required. The standard warranty period is one year for systems and ninety days for parts and service.
Revenue Recognition
The Company recognizes revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects 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 the Company satisfies a performance obligation, as further described below.
Performance obligations include sales of systems, WaferPak 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, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled. The Company generally does not grant return privileges, except for defective products during the warranty period.
For contracts that contain multiple performance obligations, the Company allocates 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.
The Company has elected the practical expedient to not assess whether a contract has a significant financing component as the Company’s standard payment terms are less than one year.
The Company sells its products primarily through a direct sales force. In certain international markets, the Company sells its products through independent distributors.
Shipping And Handling Costs
Amounts billed to customers for shipping and handling of products are included in revenue. Costs incurred related to shipping and handling of products are included in cost of revenue.
Stock-based Compensation Expense
Stock-based compensation expense consists of expenses for stock options, restricted stock units (“RSUs”), performance RSUs (“PRSUs”), and an employee stock purchase plan (“ESPP”). Stock-based compensation cost for stock options and ESPP purchase rights is measured at each grant date, based on the fair value of the award using the Black-Scholes option valuation model, and is recognized as expense over the employee’s requisite service period. For RSUs, PRSUs, restricted shares and performance restricted shares, stock-based compensation expense is based on the fair value of the Company’s common stock at the grant date, and is recognized as expense over the employee’s requisite service period. All of the Company’s stock-based compensation is accounted for as an equity instrument.
The Company grants cash-settled Stock Appreciation Rights (“SARs”) to certain employees. These awards generally vest over a one-year period of continuous service and have a contractual term of one year. Participants must be full-time employees at the time of payment and are entitled to receive a cash payment equal to the excess, if any, of the Company's common stock closing market price at the reporting date over the stock price on the grant date. No cash payment is made if the stock price at the reporting date is lower than the grant-date stock price. Because the awards are settled in cash, they are accounted for as liability-classified awards. The related liability and compensation expense are recognized over the one-year vesting period. The liability is remeasured at fair value at the end of each reporting period until the awards vest, with changes in fair value recognized as adjustments to compensation expense.

Income Taxes
The Company accounts for income taxes in accordance with the authoritative guidance, which requires income tax effects for changes in tax laws to be recognized in the period in which the law is enacted. Deferred tax assets and liabilities are recognized for the estimated future tax effects of temporary differences between the book and tax bases of assets and liabilities. Deferred tax assets are also recognized for net operating loss and tax credit carryforwards. Deferred tax assets are offset by a valuation allowance to the extent it is more likely than not that they are not expected to be realized. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets and liabilities are adjusted for the effect of a change in tax rates, laws, or status when the change is enacted.
At each reporting date, management evaluates the realizability of the Company’s deferred tax assets and records a valuation allowance when, based on all available evidence, management concludes that it is not more likely than not that some portion or all of the Company’s deferred tax assets will be realized. This assessment requires significant judgment because it involves weighing both positive and negative evidence, with the most objective evidence generally carrying the greatest weight. In making this determination, the Company considers, among other factors: (i) recent operating results and cumulative pretax income (loss) in the United States; (ii) the duration and severity of any recent losses; (iii) projections of future taxable income based on operating plans (including expected revenues, margins, and cost structure); (iv) the availability and feasibility of tax planning strategies; and (v) the expected utilization periods and limitations applicable to carryforwards.
As of May 29, 2026 and May 30, 2025, the Company did not maintain a valuation allowance against its deferred tax assets. During the year ended May 31, 2024, the Company concluded that its deferred tax assets are more likely than not to become realizable, and as such, the Company reversed all $
The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not such tax position will be sustained on examination by the taxing authorities, based solely on the technical merits of the respective tax position. The tax benefits recognized in the consolidated financial statements from such a tax position should be measured based on the largest benefit having a greater than 50% likelihood of being realized upon ultimate settlement with the tax authority. Interest and penalties related to uncertain tax positions are recognized in the provision for income taxes.
Comprehensive Income (Loss)
Comprehensive income (loss) generally represents all changes in shareholders’ equity except those resulting from investments or contributions by shareholders. Unrealized gains and losses from available-for-sale securities and on foreign currency translation adjustments are included in the Company’s components of comprehensive income (loss), which are excluded from net income (loss). Comprehensive income (loss) is included in the consolidated statements of comprehensive income (loss).
Accounting Standards Adopted
In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which expands the disclosures required for income taxes. The Company adopted ASU 2023-09 on a prospective basis in fiscal 2026. The adoption did not have a material impact on the Company’s consolidated financial statements but resulted in expanded income tax disclosures. See Note 6, Income Taxes.
Recent Accounting Pronouncements Not Yet Adopted
In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, an accounting standard update to improve income statement expenses disclosures. The standard requires more detailed information related to the types of expenses, including (among other items) the amounts of purchases of inventory, employee compensation, depreciation and intangible asset amortization included within each interim and annual income statement’s expense caption, as applicable. This authoritative guidance can be applied prospectively or retrospectively and will be effective for fiscal years beginning after December 15, 2026, with early adoption permitted. The Company is currently evaluating the effect of this pronouncement on its disclosures.

| Table of Contents |
In July 2025, the FASB issued ASU 2025-05, Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses for Accounts Receivable and Contract Assets. The new guidance allows companies to apply a practical expedient when estimating credit losses on current accounts receivable and contract assets. This ASU is effective for fiscal years beginning after December 15, 2025. Early adoption is permitted for periods in which financial statements have not yet been issued or made ready for issuance on a prospective basis. The Company is currently evaluating the impact of adopting this guidance on its consolidated financial statements.
In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. This update clarifies certain interim reporting requirements, including the applicability of interim reporting guidance and the form and content of interim financial statements. This ASU is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting this guidance on its consolidated financial statements and related disclosures.
In December 2025, the FASB issued ASU 2025-12, Codification Improvements, which clarifies, corrects errors, and makes minor improvements to various areas of the Accounting Standards Codification. This ASU is effective for annual and interim periods in fiscal years beginning after December 15, 2026. Early adoption is permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements and related disclosures.
2. FAIR VALUE OF FINANCIAL INSTRUMENTS
The Company’s financial instruments are measured at fair value consistent with authoritative guidance. This authoritative guidance defines fair value, establishes a framework for using fair value to measure assets and liabilities, and disclosures required related to fair value measurements.
The guidance establishes a fair value hierarchy based on inputs to valuation techniques that are used to measure fair value that is either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon their own market assumptions. The fair value hierarchy consists of the following three levels:
Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
Level 2 - Inputs that are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant inputs are observable in the market or can be derived from observable market data. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including interest rate curves, foreign exchange rates, and credit ratings.
Level 3 - Unobservable inputs that are supported by little or no market activities.

During the year ended May 31, 2024, the Company concluded that its deferred tax assets are more likely than not to become realizable, and as such, the Company reversed all its existing valuation allowance totaling $
At May 29, 2026 and May 30, 2025, the Company has federal net operating loss carryforwards of approximately $
At May 29, 2026 and May 30, 2025, the Company has federal research and development credit carryforwards of approximately $
Sections 382 and 383 of the Internal Revenue Code limit the annual use of NOL carryforwards and tax credit carryforwards, respectively, following an ownership change. NOL carryforwards may be subject to annual limitations under Section 382 (or comparable provisions of state law) if certain changes in ownership of our company were to occur. In general, an ownership change occurs for the purposes of Section 382 if there is a more than 50% change in ownership of a company by 5% shareholders over a 3-year testing period. During the year ended May 31, 2024, a Section 382 study was completed and it was determined that there is no limitation on the Company’s ability to utilize its NOLs under Section 382. During the years ended May 29, 2026 and May 30, 2025, the Company did not complete a formal Section 382 study on the potential limitation of its tax attributes due to no significant change in ownership.
The Company has made no provision for U.S. income taxes on undistributed earnings of certain foreign subsidiaries because it is the Company’s intention to permanently reinvest such earnings in its foreign subsidiaries. If such earnings were distributed, the Company would be subject to additional U.S. income tax expense.
The Company maintains liabilities for uncertain tax positions and such liabilities relate primarily to estimated tax credits and are treated as a reduction of deferred tax assets for tax credit carryforward. These liabilities involve considerable judgment and estimation and are continuously monitored by management based on the best information available.

The Company’s federal and state income tax returns are subject to possible examination by the taxing authorities until the expiration of the related statutes of limitations on those tax returns. In general, the federal income tax returns have a three-year statute of limitations, and the state income tax returns have a four-year statute of limitations. The Company’s foreign income tax returns are also subject to examination by the foreign tax authorities with the longest statute of limitations period of four-year. The Company is not currently under audit with the Internal Revenue Service, or any foreign, state or local jurisdictions, nor has it been notified of any other potential future income tax audit.

7. LEASES
The Company leases its manufacturing and office space under operating leases. The principal administrative and production facility is located in Fremont, California, in a 51,289 square foot building. The
The Company has only operating leases for real estate including corporate offices, warehouse space and certain equipment. A lease with an initial term of 12 months or less is generally not recorded on the consolidated balance sheets, unless the arrangement includes an option to purchase the underlying asset, or renew the arrangement that the Company is reasonably certain to exercise. The Company recognizes lease expense on a straight-line basis over the lease term for short-term leases that the Company does not record on its consolidated balance sheets. The Company’s operating leases have remaining lease terms of one year to ten years.
The Company determines whether an arrangement is or contains a lease based on the unique facts and circumstances present at the inception of the arrangement. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected lease term. The interest rate implicit in lease contracts is typically not readily determinable. As such, the Company utilizes the appropriate incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term at an amount equal to the lease payments in a similar economic environment. Certain adjustments to the right-of-use asset may be required for items such as initial direct costs paid or incentives received.
As of May 29, 2026, the weighted average remaining lease term for the Company’s operating leases was
The Company’s operating lease cost was $

8. RETIREMENT PLAN
The Company maintains a defined contribution savings plan named AEHR Test Systems 401(k) Savings & Retirement Plan (the “401(k) Plan”) to provide retirement savings to all qualified employees of the Company. The 401(k) Plan is intended to be qualified under Section 401(k) of the Internal Revenue Code of 1986, as amended. The 401(k) Plan is funded by voluntary pre-tax contributions from employees. Contributions are invested, as directed by the participant, in investment funds available under the 401(k) Plan. Effective July 1, 2024, the Company implemented a discretionary matching contribution under its 401(k) Plan. All matching contributions are
9. COMMITMENTS AND CONTINGENCIES
Commitment
Purchase obligations consist of non-cancelable significant contractual obligations. As of May 29, 2026, the Company’s unconditional purchase obligations, which have a remaining term in excess of 12 months, were not material.
Contingencies
The Company may, from time to time, be involved in legal proceedings arising in the ordinary course of business. While there can be no assurances as to the ultimate outcome of any litigation involving the Company, management does not believe any pending legal proceedings will result in judgment or settlement that will have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows.
On October 16, 2024, the Company filed a complaint with the China Suzhou Intermediate Court to protect its intellectual property rights in China against Suzhou Semight Instruments Co., Ltd. (“Semight”) and its related entities and/or distributors, alleging infringement of the Company’s two patents related to wafer burn-in systems and wafer reliability test systems. The Company is seeking injunctive relief, claiming that Semight’s actions have infringed upon its intellectual property rights and caused substantial harm to its business. The Company believes its claims are valid and is vigorously pursuing its legal remedies. At this stage, the outcome of the litigation is uncertain, and the Company is unable to predict the likelihood of success or estimate the potential financial impact, if any, on its consolidated financial statements. The Company has also incurred and expects to continue to incur legal expenses related to this matter. On November 15 and December 6, 2024, Semight filed a petition for invalidation to the two aforementioned Chinese patents with the Department of National Intellectual Properties in Beijing, respectively. The oral hearings for both of the patents have been held, and the decision has been issued for both patents that upholds part of the claims. In addition, the Company received a suspension ruling from Suzhou Intermediate People’s Court on the infringement proceedings, pending the outcome of the validity rulings. With both patents having been upheld, the suspended infringement proceedings have resumed. The hearing for the divisional patent was held on August 28, 2025, and the hearing for the parent patent was held on October 17, 2025. In December 2025, the Company received a first-instance judgment from the Suzhou Intermediate People’s Court with respect to the infringement cases, which dismissed the Company’s claims based on the court’s opinion that there was insufficient evidence to establish infringement. The Company filed the appeals for both cases on January 4, 2026. On January 27, 2026, Semight filed another petition for invalidation of one of the two aforementioned Chinese patents with the Department of National Intellectual Properties in Beijing. On June 2, 2026, a hearing was held before the Supreme People’s Court of China in connection with the Company’s appeal. The hearing focused primarily on infringement comparison issues, including whether the accused products contain certain claim features at issue. The appeal proceedings remain ongoing, and the Company expects that an additional hearing may be scheduled. In June 2026, the Company received a first-instance judgment from the Beijing Intellectual Property Court in connection with one of the patent invalidation proceedings. The judgment was favorable to the Company on certain issues but did not resolve all matters in the Company’s favor. The Company has decided to appeal certain aspects of the judgment.

| Table of Contents |
In the normal course of business to facilitate sales of its products, the Company indemnifies other parties, including customers, with respect to certain matters, for example, including against losses arising from a breach of representations or covenants, or from intellectual property infringement or other claims. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. In addition, the Company has entered into indemnification agreements with its officers and directors, and the Company’s bylaws contain similar indemnification obligations to the Company’s agents.
It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. To date, payments made by the Company under these agreements have not had a material impact on the Company’s operating results, financial position or cash flow.

Contract Balances
Accounts receivable are recognized in the period the Company delivers goods and provides services or when the Company’s right to consideration is unconditional. Contract assets include unbilled receivables which represent revenues that are earned in advance of scheduled billings to customers. These amounts are primarily related to product sales where transfer of control has occurred but the Company has not yet invoiced. As of May 29, 2026 and May 30, 2025, unbilled receivables were $
Contract liabilities include payments received in advance of performance under a contract and are satisfied as the associated revenue is recognized. Contract liabilities as of May 29, 2026 and May 30, 2025 were $
Remaining Performance Obligations
As of May 29, 2026, the remaining performance obligations, exclusive of customer deposits, which were comprised of deferred service contracts and extended warranty contracts not yet delivered, are not material. The foregoing excludes the value of the remaining performance obligations that have original durations of one year or less, and also excludes information about variable consideration allocated entirely to a wholly unsatisfied performance obligation.
Costs to Obtain or Fulfill a Contract
The Company generally expenses sales commissions when incurred as a component of selling, general and administrative expense as the amortization period is typically less than one year. Additionally, the majority of the Company’s cost of fulfillment as a manufacturer of products is classified as inventory and fixed assets, which are accounted for under the respective guidance for those asset types. Other costs of contract fulfillment are immaterial due to the nature of the Company’s products and their respective manufacturing process.

2023 Equity Incentive Plan

The 2023 Plan permits grants to employees of share-based awards, including stock options, RSUs, PRSUs, restricted shares, performance restricted shares. Full value awards, which are equity awards other than options, stock appreciation rights or other awards that are based solely on an increase in value of the shares following the grant date, when granted or forfeited will be counted as the same number of common stock shares added or deducted to the remaining available shares for issuance under the 2023 Plan.
On October 20, 2025, the Company’s shareholders approved amendments to the 2023 Equity Incentive Plan to increase the share reserves by
2016 Equity Incentive Plan
In October 2016, the Company’s 2016 Plan was approved by the Company’s shareholders. The 2016 Plan replaced the 2006 Equity Incentive Plan and would continue in effect until 2026. The exercise price of each stock option equals the market value of the Company's common stock on the date of grant. Options typically vest over four years, subject to the grantee’s continued service with the Company through the scheduled vesting date, and expire in seven years from the grant date. A total of

As of May 29, 2026, the total unrecognized compensation expense related to unvested stock options granted and outstanding is immaterial.
Stock Appreciation Rights (Cash-Settled Awards)
The Company grants cash-settled Stock Appreciation Rights (“SARs”) to certain employees. These awards generally vest over a one-year period of continuous service and have a contractual term of one year. Participants must be full-time employees at the time of payment and are entitled to receive a cash payment equal to the excess, if any, of the Company's common stock closing market price at the reporting date over the stock price on the grant date. No cash payment is made if the stock price at the reporting date is lower than the grant-date stock price. Because the awards are settled in cash, they are accounted for as liability-classified awards. The related liability and compensation expense are recognized over the one-year vesting period. The liability is remeasured at fair value at the end of each reporting period until the awards vest, with changes in fair value recognized as adjustments to compensation expense.

Employee Stock Purchase Plan
The ESPP permits employees to purchase common stock at a discount through payroll withholdings at certain specified dates (purchase period) within a defined offering period. The purchase price is 85.0% of the fair market value of the common stock at the end of the purchase period and is intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code.
On October 20, 2025, the Company’s shareholders approved amendments to the Amended and Restated 2006 Employee Stock Purchase Plan to increase the share reserves by

15. NET INCOME (LOSS) PER SHARE
Basic net income (loss) per share is determined using the weighted average number of common shares outstanding during the period. Diluted net income per share is determined using the weighted average number of common shares and potential common shares (representing the hypothetical number of incremental shares issuable under the assumed exercise of outstanding stock options, and vesting of outstanding RSUs and ESPP shares) during the period using the treasury stock method. The calculation of dilutive shares outstanding excludes securities that would have an antidilutive effect on net income per share.

17. SEGMENT INFORMATION
The Company's chief executive officer, who is the chief operating decision maker ("CODM"), reviews discrete financial information presented at the consolidated basis, to assess performance and allocate resources. There are no segment managers who are held accountable for operations or operating results below the consolidated unit level. Accordingly, the Company has only one operating and reportable segment. The measure of segment profit or loss that our CODM uses to allocate resources and assess performance is our consolidated net income (loss).
The information for revenue category by type, geography and timing of revenue recognition, is summarized in Note 11, “Revenue.”
The CODM reviews consolidated expense information under the categories that are reported on the consolidated statement of operations, for the purpose of allocating resources and evaluating financial performance.
