1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCCOUNTING POLICIES

The accompanying financial information has been prepared by Aehr Test Systems, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) have been condensed or omitted pursuant to such rules and regulations.

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, 20202021 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 and notes thereto should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended May 31, 2020.2021. Results for the interim periods presented herein are not necessarily indicative of results which may be reported for any other interim period or for the entire fiscal year.

The Company (as defined below) has been impacted by the outbreak of the novel coronavirus, known as COVID-19, which has spread throughout the world. Due to the impact of the COVID-19 pandemic on customers and customers’ customers, the Company experienced a drop in customer orders and revenues during the fiscal year ended May 31, 2021 and in the last quarter of fiscal year ended May 31, 2020. In response, the Company implemented cost reduction initiatives to mitigate operating losses, including mandatory vacation days, shutdown days, and executive staff pay reductions. The Company eliminated all cost reduction initiatives in the last quarter of the fiscal year ended May 31, 2021.

The Company will continue to monitor the situation. As of the date of this report, the Company cannot predict with certainty the potential effects the COVID-19 pandemic may have on the Company’s business and its operating results. While the overall environment remains uncertain, the Company continues to invest in priority areas with the objective of driving profitable growth over the long term.

PRINCIPLES OF CONSOLIDATION. The condensed consolidated financial statements include the accounts of Aehr Test Systems and its subsidiaries (collectively, the "Company"). On November 18, 2020, the Company established a wholly owned new subsidiary, Aehr Test Systems Philippines, which is in full operation as of March 31, 2021. All significant intercompany balances have been eliminated in consolidation. For the Company's majority owned subsidiary,The liquidation of Aehr Test Systems Japan K.K. (“ATS-Japan”), the Company’s majority owned subsidiary, was completed on July 31, 2020 and noncontrolling interest of the portion the Company does not own was reflected on the Condensed Consolidated Balance Sheets in Sharholders' Equity and in the Condensed Consolidated Statements of Operations.

ACCOUNTING ESTIMATES. 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 and 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. Estimates are used to account for sales and revenue allowances, the allowance for doubtful accounts, inventory valuations, income taxes, stock-based compensation expenses, and product warranties, among others. The Company bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under the circumstances. Actual results could differ materially from those estimates.

2. RECENT ACCOUNTING PRONOUNCEMENTS

Accounting Standards Adopted

Income Taxes

On December 18, 2019, the FASB issued Accounting Standards Update ASU 2019-12 on Simplifying the Accounting for Income Taxes. The board decided to remove the exception to the incremental approach for intra-period tax allocation when there is a loss from continuing operations and income or gain from other items (for example discontinued operations or other comprehensive income). There are also provisions related to state taxes and calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2020. The Company has adopted ASU 2019-12 in the quarter ended August 31, 2021 with no material impact.

3. REVENUE

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, 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. Revenue from services is recognized over time as services are completed or ratably 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 following tables show revenues by major product categories. Within each product category, contract terms, conditions and economic factors affecting the nature, amount, timing and uncertainty around revenue recognition and cash flow are substantially similar.

The Company’s revenues by product category are as follows (in thousands):

The following presents information about the Company’s operations in different geographic areas. Net sales are based upon ship-to location (in thousands):

With the exception of the amount of service contracts and extended warranties, the Company’s product category revenues are recognized at a point in time when control transfers to the customers. The following presents revenue based on timing of recognition (in thousands):

A receivable is recognized in the period the Company delivers goods or provides services or when the Company’s right to consideration is unconditional. The Company usually does not record contract assets because the Company has an unconditional right to payment upon satisfaction of the performance obligation, and therefore, a receivable is more commonly recorded than a contract asset.

Contract liabilities include payments received in advance of performance under a contract and are satisfied as the associated revenue is recognized. Contract liabilities are reported on the Condensed Consolidated Balance Sheets at the end of each reporting period as a component of deferred revenue. Contract liabilities as of August 31, 20202021 and May 31, 20202021 were $406,000$3,429,000 and $192,000,$288,000, respectively. During the three months ended August 31, 2020,2021, the Company recognized $79,000$109,000 of revenues that were included in contract liabilities as of May 31, 2020.

On August 31, 2020,2021, the Company had $128,000$258,000 of remaining performance obligations, which were comprised of deferred service contracts and extended warranty contracts not yet delivered. The Company expects to recognize approximately 66%29% of its remaining performance obligations as revenue in fiscal 2021,2022, and an additional 34%71% in fiscal 20222023 and thereafter. The foregoing excludes the value of other remaining performance obligations as they have original durations of one year or less, and also excludes information about variable consideration allocated entirely to a wholly unsatisfied performance obligation.

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.

4. EARNINGS PER SHARE

Basic earnings per share is determined using the weighted average number of common shares outstanding during the period. Diluted earnings per share is determined using the weighted average number of common shares and potential common shares (representing the dilutive effect of stock options, restricted stock units (“RSUs”), and Amended and Restated 2006 Employee Stock Purchase Plan (“ESPP”) shares) outstanding during the period using the treasury stock method.

The following table presents the computation of basic and diluted net income (loss) per share attributable to Aehr Test Systems common shareholders (in thousands, except per share data):

For the purpose of computing diluted earnings per share, the weighted average number of potential common shares doesdo not include stock options with an exercise price greater than the average fair value of the Company’s common stock for the period, as the effect would be anti-dilutive. Stock options to purchase 112,000 shares of common stock were outstanding for the three months ending August 31, 2021, but were not included in the computation of diluted net income per share, because the inclusion of such shares would be anti-dilutive. Stock options to purchase 2,594,000 shares of common stock were outstanding as offor the three months ending August 31, 2020, but were not included in the computation of diluted net income per share, because the inclusion of such shares would be anti-dilutive. In the three months ended August 31, 2019, potential common shares were not included in the calculation of diluted net loss per share as the effect would be anti-dilutive. As such, the numerator and the denominator used in computing both basic and diluted net loss per share for these periods are the same. Stock options to purchase 3,434,000 shares of common stock, RSUs for 20,000 shares and ESPP rights to purchase 297,000 ESPP shares were outstanding as of August 31, 2019, but were not included in the computation of diluted net loss per share because the inclusion of such shares would be anti-dilutive.

5. 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 are 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 - instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets.

Level 2 - instrument valuations are obtained from readily-available pricing sources for comparable instruments.

Level 3 - instrument valuations are obtained without observable market values and require a high level of judgment to determine the fair value.

The following table summarizes the Company’s financial assets measured at fair value on a recurring basis as of August 31, 20202021 (in thousands):
