Overview

We are a leading provider of test solutions for testing, burning-in, and stabilizing semiconductor devices in wafer level, singulated die, and package part form, and have installed thousands of systems worldwide. The rapid advancement of generative artificial intelligence (AI) and the accelerating electrification of transportation and global infrastructure represent two of the most significant macro-trends impacting the semiconductor industry today. These transformative forces are driving enormous growth in semiconductor demand while fundamentally increasing the performance, reliability, safety, and security requirements of the devices used across computing and data infrastructure, telecommunications networks, hard disk drive and solid-state storage solutions, electric vehicles, charging systems, and renewable energy generation. As these applications operate at ever-higher power levels and in increasingly mission-critical environments, the need for comprehensive test and burn-in has become more essential than ever. Semiconductor manufacturers are turning to advanced wafer-level and package-level burn-in systems to screen for early-life failures, validate long-term reliability, and ensure consistent performance under extreme electrical and thermal stress. This growing emphasis on reliability testing reflects a fundamental shift in the industry-from simply achieving functionality to guaranteeing dependable operation throughout a product's lifetime, a requirement that continues to expand alongside the scale and complexity of next-generation semiconductor devices.

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 used in artificial intelligence. 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.

In connection with the acquisition of Incal Technology, Inc. ("Incal"), our product portfolio further expanded to include packaged parts burn-in solutions for the full range of power and complexity of integrated circuits. Incal's product lines feature the Sonoma series for ultra-high-power burn-in testing, the Tahoe series for medium-power reliability burn-in, and the Echo series for low-power and high parallelism testing. The Sonoma line, with its ultra-high-power capabilities, is specifically designed to address the reliability and burn-in needs of the burgeoning demand for AI accelerators, graphics processing units ("GPUs"), high-performance computing ("HPC") processors, and devices that can reach over a thousand watts of power per device. The Tahoe and Echo lines for medium-power and low-power burn-in solutions, respectively, target logic, system on a chip ("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 net 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.

Critical Accounting Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our Condensed Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these Condensed 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, assumptions and judgments, including those related to customer programs and incentives, inventories, and income taxes. 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. For a discussion of the critical accounting policies, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies and Estimates" in our Annual Report on Form 10-K for the fiscal year ended May 30, 2025.

There have been no material changes to our critical accounting policies and estimates during the three months ended August 29, 2025, compared to those discussed in our Annual Report on Form 10-K for the fiscal year ended May 30, 2025.

Net Cash Flows Provided by (Used in) Operating Activities

The $2.7 million decrease in cash flows from operating activities for the three months ended August 29, 2025, compared to the same period in the prior year, was driven primarily by a lower income (loss) before income tax (benefit), a decrease in cash provided by deferred revenue due to timing of customer deposits and revenue recognition, an increase in cash used to pay down accounts payable, and a decrease in cash provided by collection of accounts receivable due to the lower revenue, partially offset by a decrease in cash used in inventory purchase due to anticipated lower customer demand, a decrease in cash used in prepaid expenses and higher non-cash charges including stock-based compensation expense and depreciation and amortization.

Net Cash Flows Used in Investing Activities

Net cash used in investing activities decreased by $9.4 million for the three months ended August 29, 2025 compared to the same period in the prior year. The decrease was primarily due to the $10.6 million payment to acquire Incal during the three months ended August 30, 2024, partially offset by a $1.2 million increase in cash spending on property and equipment, primarily related to office renovation.

Net Cash Flows Used in Financing Activities

Net cash used in financing activities did not change materially for the three months ended August 29, 2025, compared to the same period in the prior year.

Off-Balance Sheet Agreements

We do not have any off-balance sheet arrangements, investments in special purpose entities or undisclosed borrowings or debt. There have been no material changes in the composition, magnitude or other key characteristics of our contractual obligations or other commitments as disclosed in the Company's Annual Report on Form 10-K for the year ended May 30, 2025.
