NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Organization

Aehr Test Systems (the “Company”) was incorporated in California in May 1977 and develops 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 and singulated die/module parallel test and burn-in systems, the Sonoma, Tahoe and Echo packaged parts burn-in products, the WaferPak full wafer contactor, the DiePak carrier, the WaferPak aligner, the DiePak autoloader, and test fixtures.

Basis of Presentation

The unaudited Condensed Consolidated Financial Statements included in this quarterly report on Form 10-Q include the accounts of the Company and its wholly-owned subsidiaries and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial reporting and the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim reporting. Accordingly, the unaudited Condensed Consolidated Financial Statements do not include certain information and footnote disclosures normally included in the annual consolidated financial statements. In the opinion of management, the unaudited Condensed Consolidated Financial Statements for the interim periods presented have been prepared on a basis consistent with the May 31, 2024 audited Consolidated Financial Statements and reflect all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the condensed consolidated financial position and results of operations as of and for such periods indicated. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended May 31, 2024.

Beginning on June 1, 2024, the Company changed its fiscal year to the 52- or 53-week period ending on the Friday nearest May 31. The ~~second~~third fiscal quarter in fiscal 2025 ended on ~~November~~February 2928, ~~2024~~2025 and the Company’s fiscal year 2025 will end on May 30, 2025.

Principles of Consolidation

The Company’s Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries and all significant intercompany accounts and transactions have been eliminated upon consolidation.

Reclassifications

Certain reclassifications have been made to prior period footnote disclosures to conform to the current period presentation. These reclassifications had no impact on the condensed consolidated financial statements, including net income, total assets, total liabilities, or shareholders’ equity.

Critical Accounting Policies and use of Estimates

The Company’s significant accounting policies are disclosed in the Company’s Annual Report on Form 10-K for the year ended May 31, 2024. Except for the accounting policies related to Business Combination and Goodwill and Intangible Assets, as discussed below, there have been no significant changes to these accounting policies during the three and ~~six~~nine months ended ~~November~~February 2928, ~~2024~~2025. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Critical accounting estimates in these Condensed Consolidated Financial Statements include valuation of inventory at the lower of cost or net realizable value, valuation of intangible assets and impairment of long-lived assets and goodwill. Actual results could differ from those estimates.

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. There was no impairment recorded during the three and ~~six~~nine months ended ~~November~~February 2928, ~~2024~~2025 and ~~November~~February 3029, ~~2023~~2024.

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 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:

2. BUSINESS COMBINATION

On July 31, 2024, the Company completed its acquisition of Incal Technology, Inc. (“Incal”), a company that specializes in packaged part reliability/burn-in test solutions. The acquisition date fair value of the consideration transferred for Incal was approximately $22.2 million, which consisted of the following:

(In thousands)	Fair Value
Cash	$	10,631
Common stock under transfer restriction		9,381
Escrow payable		2,381
Working capital adjustments (1)		(240	)
Working capital adjustments		(240	)
Total	$	22,153

(1) Included in Prepaid expenses and other current assets

As part of the purchase consideration, the Company issued 552,355 shares of its restricted common stock. The restricted stock issued to the shareholders of Incal is subject to a six-month holding period, during which time the shares cannot be transferred or sold without registration under the Securities Act of 1933, as amended, or pursuant to an available exemption. The fair value of the restricted shares was determined based on the closing price of the Company’s common stock on the acquisition date, adjusted for a discount related to the lack of marketability due to the transfer restrictions. The total fair value of the restricted shares issued as part of the consideration was $9.4 million.

The escrow payable ~~recorded at the acquisition date~~ represented the present value of total escrow amount, net of certain indemnification, and was initially recorded within Accrued expenses and other current liabilities and Other long-term liabilities, respectively. The total escrow amount at the acquisition date included: (1) $2.1 million designated for the sellers' indemnification obligations and expected to be settled after 15 months, and (2) $0.7 million designated for the sellers' payment obligations and expected to be settled after 60 days. The escrow payable will be settled with cash of $2.8 million held in an escrow account for working capital adjustments and potential indemnification obligations in connection with the acquisition of Incal. Of the $2.8 million cash restricted in escrow, the Company initially recorded $0.7 million iswithin ~~included in~~ Prepaid expenses and other current assets and $2.1 million iswithin ~~included in~~ Other noncurrent assets.

During the three months ended November 29, 2024, the Company updated the purchase consideration, which reflects a reduction in the receivable related to the working capital adjustment from $0.8 million to $0.2 million and a reduction in escrow payable related to indemnification from $2.8 million to $2.5 million, based on negotiations with the seller. As a result, the total purchase consideration has been adjusted from $21.9 million to $22.2 million. Accordingly, the goodwill balance has increased from $10.4 million to $10.7 million.

Total intangible assets acquired	$	12,000

Acquisition-related costs were not significant and $0.5 million for the ~~six~~three and nine months ended ~~November~~February 2928, ~~2024~~2025, respectively, and were expensed in the period incurred within selling, general and administrative expense in the Company's Condensed Consolidated Statements of Operations.

The Company's Condensed Consolidated Statement of Operations includes $58.09 million in revenue and $0.4 million in net income contributed by Incal from the date of acquisition. Pro forma results of operations for this acquisition have not been presented, as the acquisition was ~~not~~ determined to be not significant as of the date of acquisition.

The purchase consideration allocation remains preliminary, and as additional information becomes available, the Company may further revise it during the remainder of the measurement period.

3. FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company measures its cash equivalents and money market funds at fair value on a recurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. Assets and liabilities recorded at fair value are measured and classified in accordance with a three-tier fair value hierarchy based on the observability of the inputs available in the market used to measure fair value:

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.

Product warranties

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.

The following is a summary of changes in the Company's liability for product warranties during the three and ~~six~~nine months ended ~~November~~February 2928, ~~2024~~2025 and ~~November~~February 3029, ~~2023~~2024:

The Company accounts for uncertain tax positions consistent with authoritative guidance. The guidance prescribes a “more likely than not” recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income taxes.

Table of Contents

Tax expense for the three and nine months ended February 29, 2024 was primarily due to profitable foreign subsidiaries. Provision for income taxes for the three and nine months ended February 29, 2024 did not included tax expense related to U.S. operations due to a valuation allowance. The Company maintained a full valuation allowance on all the U.S. net deferred tax assets through the first nine months of fiscal 2024. In the fourth quarter of fiscal 2024, the Company concluded that the valuation allowance related to the U.S. federal and state deferred tax assets was no longer required due to existence of sufficient positive evidence to support that it is more likely than not that its deferred tax assets are realizable. A significant income tax benefit of $21.9 million was recognized due to release of a valuation allowance in the fourth quarter of fiscal 2024.

7. COMMITMENTS AND CONTINGENCIES

Purchase Obligations

The Company has purchase obligations to certain suppliers. In some cases, the products the Company purchases are unique and have provisions against cancellation of the order.

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 December 3, 2024, a putative shareholder class action lawsuit captioned Lucid Alternative Fund, LP v. Aehr Test Systems, Inc. was filed in the United States District Court for the Northern District of California against the Company. The lawsuit alleges, in part, that the Company and certain of its executives made materially false and misleading statements regarding the Company’s earnings guidance and other financial projections for 2024. The lawsuit seeks unspecified monetary damages and purports to represent purchasers of the Company’s securities between January 9, 2024 and March 24, 2024. ~~Additionally~~On February 3, 2025, Lucid and individual investor Yue Guo each filed motions requesting appointment as lead plaintiff. On March 19, 2025, the court appointed Yue Guo, who is represented by Rosen Law, as lead plaintiff in the shareholder class action. On April 4, 2025, the court ordered lead plaintiff to file an amended complaint or designate the existing complaint as operative by May 16, 2025; defendants to file their anticipated motion to dismiss by June 6, 2025; lead plaintiff to respond to the motion by June 27, 2025; and defendants to reply by July 11, 2025. The court scheduled a hearing on defendants’ motion to dismiss for August 8, 2025. Additionally, two shareholder derivative ~~complaint~~complaints ~~was~~have been filed, alleging breaches of fiduciary duties and other misconduct by certain directors and officers of the Company. The derivative complaints have been consolidated before the same judge as the putative shareholder class action lawsuit, but the court has not yet entered a schedule for defendants to respond to the complaints. The Company believes the claims in all three lawsuits are meritless and intends to vigorously defend its position. Given the procedural posture and the nature of the ~~case~~cases, including that the pending ~~proceeding~~proceedings isare in the early stages, that alleged damages have not been specified, that uncertainty exists as to the likelihood of a class or classes being certified or the ultimate size of any class or classes if certified, and that there are significant factual and legal issues to be resolved, the Company is unable to make a reasonable estimate of the potential loss or range of losses, if any, that might arise from ~~this~~these ~~matter~~matters.

On October 1816, 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 condensed 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 196, 2024, Semight filed a petition for acceptance of request 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 is expected within one to three months. 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.

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.

8. SHAREHOLDERS’ EQUITY

On August 25, 2021, the Board of Directors authorized management to take actions necessary for the execution of a $75 million shelf registration. A Registration Statement on Form S-3 was filed with the SEC on September 3, 2021. A Prospectus Supplement for an "At the Market" ("ATM") sale of up to $25 million of common stock was subsequently filed on September 17, 2021. The Company sold 1,696,729 shares of common stock at an average selling price of $14.73 per share between September and October 2021. The gross proceeds to the Company were $25.0 million, before commission fees of $0.7 million and offering expenses of $0.3 million. Another Prospectus Supplement for an ATM sale of up to $25 million of common stock was subsequently filed on February 8, 2023. The Company sold 208,917 shares of common stock at an average selling price of $34.78 per share in February 2023. The gross proceeds to the Company during the quarter ended February 28, 2023 were $7.3 million, before commissions of $0.2 million and offering expenses of $0.2 million. The 2021 registration statement expired in September 2024.

On October 15, 2024, the Board of Directors authorized management to execute a new $100 million shelf registration, and a Registration Statement on Form S-3 was filed with the SEC. Additionally, a Prospectus Supplement for an ATM offering of up to $40 million of common stock was filed. No proceeds were raised from the ATM during the three and ~~six~~nine months ended ~~November~~February 2928, ~~2024~~2025. The remaining amount of the ATM offering was $40 million as of ~~November~~February 2928, ~~2024~~2025.

9. REVENUE

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, contactors, spare parts, 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.

Contract balances

Accounts receivable are recognized in the period the Company delivers goods or provides services and 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 ~~November~~February 2928, ~~2024~~2025 and May 31, 2024, unbilled receivables were $03.20 million and $0.2 million, respectively, and were included in prepaid expenses and other current assets on the accompanying Condensed Consolidated Balance Sheets.

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 ~~November~~February 2928, ~~2024~~2025 and May 31, 2024 were $0.79 million and $1.4 million, respectively, and were included in deferred revenue, short-term and deferred revenue, long-term on the accompanying Condensed Consolidated Balance Sheets. During the ~~three~~nine ~~and six~~ months ended ~~November~~February 2928, ~~2024~~2025, the Company recognized $01.062 million ~~and~~in ~~$1.1~~revenue ~~million~~which were included in ~~revenue~~contract liabilities as of May 31, ~~respectively~~2024. During the three months ended February 28, ~~which~~2025, ~~were~~the amount recognized in revenue that was previously included in contract liabilities as of May 31, 2024 was not significant.

Remaining performance obligations

As of ~~November~~February 2928, ~~2024~~2025, 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 other remaining performance obligations, as they have original durations of one year or less and 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 expenses 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.

10. STOCK-BASED COMPENSATION

Stock-based compensation expense consists of expenses for stock options, restricted stock units (“RSUs”), performance RSUs (“PRSUs”), restricted shares, performance restricted shares and employee stock purchase plan (“ESPP”) purchase rights. Stock-based compensation expense 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. This model was developed for use in estimating the value of publicly traded options that have no vesting restrictions and are fully transferable. The Company’s employee stock options have characteristics significantly different from those of publicly traded options. 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 equity instruments. See Note 11 in the Company’s Annual Report on Form 10-K for fiscal 2024 filed on July 30, 2024 for further information regarding the equity incentive plans and the ESPP.

11. 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 (loss) 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.

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. Decarbonization, generative AI and digitalization is driving increased quality, reliability, safety, and security needs of semiconductors used across multiple applications, including electric vehicles, electric vehicle charging infrastructure, solar and wind power, computing, data and telecommunications infrastructure, and solid-state memory and storage. The trend is driving additional test requirements, incremental capacity needs, and new opportunities for our 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 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, GPUs, high-performance computing (HPC) processors, and devices that can reach levels of power as high as 1600W. The Sonoma is available in its standard configuration, which hosts up to 22 slots per chamber, and in its production version, which has 12 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 net revenue consists primarily of sales of FOX-P systems, Sonoma/Tahoe/Echo systems, WaferPak Aligners and DiePak Loaders, WaferPak contactors, DiePak carriers, 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 31, 2024.

Except for the critical accounting estimates related to Business Combination and Impairment of Goodwill and Long-lived Assets newly discussed below, there have been no material changes to our critical accounting policies and estimates during the ~~six~~nine months ended ~~November~~February 2928, ~~2024~~2025 compared to those discussed in our Annual Report on Form 10-K for the fiscal year ended May 31, 2024.

Business Combinations 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.

Impairments of Long-Lived Assets We monitor the carrying value of long-lived assets for potential impairment each quarter based on whether certain triggering events have occurred. These events include current period losses combined with a history of losses, or a projection of continuing losses, or a significant decrease in the market value of an asset. When a triggering event occurs, we perform an impairment calculation, comparing projected undiscounted cash flows, utilizing current cash flow information and expected growth rates, to the carrying value of the assets. If we identify impairment for long-lived assets to be held and used, we compare the assets’ current carrying value to the assets’ fair value. Fair value is determined based on market values or discounted future cash flows. We record impairment when the carrying value exceeds fair market value.

We have not recorded any impairment charges during the three and ~~six~~nine months ended ~~November~~February 2928, ~~2024~~2025 and ~~November~~February 3029, ~~2023~~2024.

The $6.8 million decrease in cash flows from operating activities for the six months ended November 29, 2024, compared to the six months ended November 30, 2023, was driven primarily by a net loss in the current period, compared to a net income in the prior period, and a decrease in cash provided by collection of accounts receivable due to lower revenue, which were partially offset by a decrease in cash used in procuring inventory and payments to vendors and a smaller reduction in deferred revenue due to timing of customer deposits and revenue recognition.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer, or CEO, and chief financial officer, or CFO, evaluated the effectiveness of our "disclosure controls and procedures" as defined in Exchange Act Rules 13a-15(e) and 15d-15(e) as of ~~November~~February 2928, ~~2024~~2025, in connection with the filing of this Quarterly Report on Form 10-Q. Based on that evaluation as of ~~November~~February 2928, ~~2024~~2025, our CEO and CFO concluded that our disclosure controls and procedures were effective to ensure that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in rules and forms of the SEC and accumulated and communicated to our management as appropriate to allow timely decisions regarding required disclosures.

There were no changes in the Company's internal control over financial reporting during the three months ended ~~November~~February 2928, ~~2024~~2025, that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

Item 1A. Risk Factors

Item 1A, “Risk Factors,” on pages 11 through 18 of the Company’s Annual Report on Form 10-K for the year ended May 31, 2024, provides information on the significant risks associated with our business. Since the filing of the Annual Report, we have identified the following material risk factor:

Geopolitical Tensions and Changes in Government Trade Policies Could Adversely Affect Our Operations in China and Our Business, Results of Operations and Financial Condition

Heightened geopolitical tensions between the United States and China could create barriers to selling our products and services to customers in China as there is currently significant uncertainty about the future relationship between the United States and China with respect to trade policies, treaties, tariffs and taxes. These barriers may include increased tariffs and other trade barriers, regulatory restrictions, or limitations on technology transfer. Any such developments, including changes in trade policies, export and import restrictions, or diplomatic relations under the current or future administration, could adversely affect our ability to compete in the Chinese market and impair our growth prospects in China, as well as our business, results of operations, and financial condition.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

None.

Item 3. Defaults Upon Senior Securities

None.

Item 4. Mine Safety Disclosures

Not Applicable.
