NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

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, 2022 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, 2022. 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.

PRINCIPLES OF CONSOLIDATION. The condensed consolidated financial statements include the accounts of Aehr Test Systems and its subsidiaries (collectively, the "Company"). All significant intercompany balances have been eliminated in consolidation.

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 the standalone selling prices related to revenue recognition, 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.

RECLASSIFICATIONS. Certain reclassifications have been made to prior year condensed consolidated financial statements to conform to the current period presentation. The reclassifications had no impact on net loss, total assets, total liabilities, or shareholders’ equity.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES. The Company’s significant accounting policies are disclosed in the Company’s Annual Report on Form 10-K for the year ended May 31, 2022. There have been no significant changes in the Company’s significant accounting policies during the three and nine months ended February 28, 2023.

2. RECENT ACCOUNTING PRONOUNCEMENTS

Accounting Standards Not Yet Adopted

In June 2016, the Financial Accounting Standards Board issued Accounting Standard Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326), that requires measurement and recognition of expected credit losses for financial assets held based on historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Due to a subsequent ASU in November 2019, the accounting standard will be effective for the Company beginning in the first quarter of fiscal 2024 on a modified retrospective basis. The Company does not expect a material impact of this accounting standard on its condensed consolidated financial statements.

Table of Contents

3. 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, 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 are 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 Company sells its products primarily through a direct sales force. In certain international markets, the Company sells its products through independent distributors.

Transfer of control is evidenced upon passage of title and risk of loss to the customer unless we are required to provide additional services.

Disaggregation of revenue

The following tables show net sales 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.

Table of Contents

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

	$	17,206	$	15,283	$	42,692	$	30,540

Contract balances

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 February 28, 2023 and May 31, 2022 were $851,000 and $2,484,000, respectively. During the three and nine months ended February 28, 2023, the Company recognized $42,000 and $2,157,000, respectively, of revenues that were included in contract liabilities as of May 31, 2022.

Table of Contents

Remaining performance obligations

On February 28, 2023, the Company had $90,000 of remaining performance obligations, which were comprised of deferred service contracts and extended warranty contracts not yet delivered. The Company expects to recognize approximately 24% of its remaining performance obligations as revenue in the remainder of fiscal 2023, and an additional 76% in fiscal 2024 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.

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.

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 shares, restricted stock units (“RSUs”), Performance RSUs (“PRSUs”) 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 earnings per share (in thousands, except per share data):

For the purpose of computing diluted earnings per share, weighted average potential common shares do 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. In the three and nine months ended February 28, 2023, stock options to purchase 15,000 shares of common stock were outstanding, but were not included in the computation of diluted earnings per share, because the inclusion of such shares would be anti-dilutive. In the three and nine months ended February 28, 2022, stock options to purchase 11,000 shares of common stock were outstanding, but were not included in the computation of diluted earnings per share, because the inclusion of such shares would be anti-dilutive.

6. 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.

7. TRADE AND OTHER ACCOUNTS RECEIVABLE, NET

Trade accounts receivable represent customer trade receivables. As of February 28, 2023 and May 31, 2022, there were no allowances for doubtful accounts. Trade accounts receivable is derived from the sale of products throughout the world to semiconductor manufacturers, semiconductor contract assemblers, electronics manufacturers and burn-in and test service companies. Other accounts receivable represents non-customer trade related receivables that are derived from the sale of raw materials to our subcontractors. The Company’s allowance for doubtful accounts is based upon historical experience and review of trade receivables by aging category to identify specific customers with known disputes or collection issues. Uncollectible receivables are recorded as bad debt expense when all efforts to collect have been exhausted and recoveries are recognized when they are received.

9. 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 nine months ended February 28, 2023 and 2022 (in thousands):

12. INCOME TAXES

The Company is subject to U.S federal and state and foreign income taxes as a corporation. The Company’s tax provision and the resulting effective tax rate for the interim period is determined based upon its estimated annual effective tax rate adjusted for the effect of discrete items arising in that quarter. The Company recorded a provision for income tax of $17,000 and $49,000 for the three and nine months ended February 28, 2023 which consisted primarily of foreign withholding taxes and foreign income taxes. The Company recorded a provision for income tax of $24,000 and $81,000 for the three and nine months ended February 28, 2022 which consisted primarily of foreign withholding taxes and foreign income taxes. The provision for federal and state income taxes was not significant due to available net operating loss and research and development credit carryforwards.

Income taxes have been provided using the liability method whereby deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and net operating loss and tax credit carryforwards measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse, or the carryforwards are utilized. Valuation allowances are established when it is determined that it is more likely than not that such assets will not be realized.

Since fiscal 2009, a full valuation allowance was established against all deferred tax assets, as management determined that it is more likely than not that certain deferred tax assets will not be realized. The Company will adjust the valuation allowance in the period management determines it is more likely than not that deferred tax assets will or will not be realized.

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 does not expect any material change in its unrecognized tax benefits over the next twelve months. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income taxes.

13. LEASES

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 condensed 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 (short-term leases). 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 condensed consolidated balance sheets. The Company’s operating leases have remaining lease terms of 1 year to 8 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 assets may be required for items such as initial direct costs paid or incentives received.

In December 2022, the Company amended its lease agreement to extend the lease term of an existing office facility located in the United States, which is considered a lease modification not accounted for as a separate contract. The total commitments, net of tenant incentives expected to be received, under the modified lease are $8.6 million. The modified lease expires in fiscal 2031 and contains an option to further extend the lease. The lease modification resulted in an increase in the Company’s operating lease right-of-use assets and operating lease liabilities of $5.9 million each.

As of February 28, 2023, the weighted-average remaining lease term for the Company’s operating leases was 7.5 years and the weighted-average discount rate was 7.5%.

The Company’s operating lease cost was $256,000 and $634,000 for the three and nine months ended February 28, 2023, respectively. For the three and nine months ended February 28, 2022, operating lease cost was $191,000 and $576,000, respectively.

14. BORROWING AND FINANCING ARRANGEMENTS

On January 16, 2020, the Company entered into a Loan and Security Agreement (the “Loan Agreement”) with Silicon Valley Bank (“SVB”). Pursuant to the Loan Agreement, the Company may borrow up to (a) the lesser of (i) the revolving line of $4.0 million or (ii) the amount available under the borrowing base under a revolving line of credit which is collateralized by all the Company’s assets except intellectual property. The borrowing base is 80% of eligible accounts, as determined by SVB from the Company’s most recent borrowing base statement; provided, however, SVB has the right to decrease the foregoing percentage in its good faith business judgment to mitigate the impact of certain events or conditions, which may adversely affect the collateral or its value. Subject to an event of default, the principal amount outstanding under the revolving line of credit will accrue interest at a floating per annum rate equal to the greater of (a) the prime rate plus an additional percentage of up to 1%, which additional percentage depends on the Company’s adjusted quick ratio, and (b) 4.75%. Interest is payable monthly on the last calendar day of each month and the outstanding principal amount, the unpaid interest and all other obligations are due on the maturity date, which is 364 days from the effective date of January 13, 2020.

On January 14, 2021, the Company entered into the First Amendment to Loan and Security Agreement (the “Amendment”) with SVB. The Amendment, among other things, extended the Revolving Line Maturity Date to July 14, 2021; provided, however, that if the Company achieved specified operating metrics on a consolidated basis on or prior to May 31, 2021 the Amended Revolving Line Maturity Date would be extended to January 13, 2022.

On January 11, 2022, the Company entered into the Second Amendment to the Loan and Security Agreement (the “Second Amendment”) with SVB. The Second Amendment, among other things, (A) increased the available amount of the line up to the lesser of (i) $10 million or (ii) the available amount under the borrowing base, under a revolving line of credit, (B) allowed for borrowing up to $3 million of the available balance based upon eligible customer purchase orders, (C) reduced the interest rate for account advances under the line to the greater of (a) prime rate plus an additional percentage up to 1.0%, which additional percentage depends on the Company’s adjusted quick ratio, and (b) 3.25%, reduces the interest rate for purchase order advances under the line to the greater of (a) prime rate plus an additional percentage up to 1.5%, which additional percentage depends on the Company’s adjusted quick ratio, and (b) 3.75%, and (D) extended the maturity date to January 13, 2023.

On January 10, 2023, the Company entered into the Third Amendment to the Loan and Security Agreement (the “Third Amendment”) with SVB. The Third Amendment, among other things, extends the Revolving Line Maturity Date to January 13, 2024, provided, however, that (i) if the Company submits a fiscal year 2024 plan of record that is generally acceptable to SVB, and (ii) the minimum net liquidity at the end of November 30, 2023 is at least $20.0 million, the Amended Revolving Line Maturity Date would be extended to January 13, 2025.

As of February 28, 2023 the Company had not drawn against the credit facility and was in compliance with all covenants related to obligations to meet reporting requirements. The balance available to borrow under the line as of February 28, 2023 was $6,949,000. There are no financial covenants in the agreement.

15. LONG-TERM DEBT:

On April 23, 2020, the Company obtained the Paycheck Protection Program Loan (the “PPP Loan”) in the aggregate amount of $1,679,000 from SVB. The PPP Loan was evidenced by a promissory note dated April 23, 2020 (the “Note”) that matured on April 23, 2022 and bore interest at a rate of 1% per annum, payable monthly commencing on November 23, 2020. The PPP Loan proceeds were used for payroll, health care benefits, rent and utilities.

Under the terms of the CARES Act, PPP loan recipients can apply for and be granted forgiveness for all or a portion of loans granted under the PPP. On June 12, 2021, the Company received confirmation from SVB that, on June 4, 2021, the Small Business Administration approved the Company’s PPP Loan forgiveness application for the entire PPP Loan balance of $1,679,000 and interest totaling $19,000, and the Company recognized a gain on loan forgiveness of $1,698,000.

16. STOCK-BASED COMPENSATION

Stock-based compensation expense consists of expenses for stock options, RSUs, PRSUs, restricted shares, performance restricted shares and 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 and restricted shares, stock-based compensation cost is based on the fair value of the Company’s common stock at the grant date. All of the Company’s stock-based compensation is accounted for as an equity instrument. See Note 11 in the Company’s Annual Report on Form 10-K for fiscal 2022 filed on August 26, 2022 for further information regarding the 2016 Equity Incentive Plan (the “2016 Plan”) and the ESPP.

The following table summarizes the stock-based compensation expense for the three and nine months ended February 28, 2023 and 2022 (in thousands):

	Three Months Ended				Nine Months Ended
	February 28,				February 28,
	2023		2022		2023		2022
Stock-based compensation in the form of stock options, RSUs, restricted shares and ESPP purchase rights, included in:

Total stock-based compensation	$	592	$	880	$	2,095	$	2,186

As of February 28, 2023, there were $110,000 stock-based compensation expenses capitalized as part of inventory. As of February 28, 2022, there were no stock-based compensation expenses capitalized as part of inventory.

During the three months ended February 28, 2023 and 2022, the Company recorded stock-based compensation expense related to stock options, RSUs, PRSUs, performance restricted shares and restricted shares under the 2016 Plan of $424,000 and $516,000, respectively. During the nine months ended February 28, 2023 and 2022, the Company recorded stock-based compensation expense related to stock options, RSUs and restricted shares of $1,536,000 and $1,416,000, respectively. For Performance RSUs and performance restricted shares, the Company evaluates compensation expense quarterly and recognizes expense for performance-based awards only if it determines it is probable that performance criteria for the awards will be met.

Table of Contents

As of February 28, 2023, the total compensation expense related to unvested stock-based awards under the 2016 Plan, but not yet recognized, was approximately $3,348,000, which is net of estimated forfeitures of $8,000. This expense will be amortized on a straight-line basis over a weighted average period of approximately 2.1 years.

During the three months ended February 28, 2023 and 2022, the Company recorded stock-based compensation expense related to the ESPP of $168,000 and $364,000, respectively. During the nine months ended February 28, 2023 and 2022, the Company recorded stock-based compensation expense related to the ESPP of $559,000 and $770,000, respectively.

As of February 28, 2023, the total compensation expense related to purchase rights under the ESPP but not yet recognized was approximately $261,000. This expense will be amortized on a straight-line basis over a weighted average period of approximately 1.0 years.

Valuation Assumptions

Valuation and Amortization Method. The Company estimates the fair value of stock options granted using the Black-Scholes option valuation model and a single option award approach. The fair value under the single option approach is amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period.

Expected Term. The Company’s expected term represents the period that the Company’s stock-based awards are expected to be outstanding and was determined based on historical experience, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior as evidenced by changes to the terms of its stock-based awards.

Volatility. Volatility is a measure of the amounts by which a financial variable such as stock price has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period. The Company uses the historical volatility, which matches the expected term of most of the option grants, to estimate expected volatility. Volatility for each of the ESPP’s four time periods of six months, twelve months, eighteen months, and twenty-four months is calculated separately and included in the overall stock-based compensation expense recorded.

Risk-Free Interest Rate. The Company bases the risk-free interest rate used in the Black-Scholes option valuation model on the implied yield in effect at the time of option grant on U.S. Treasury zero-coupon issues with a remaining term equivalent to the expected term of the stock awards including the ESPP.

Fair Value. The fair values of the Company’s stock options granted to employees for the three and nine months ended February 28, 2023 and 2022, was estimated using the following weighted average assumptions in the Black-Scholes option valuation model:

	Three Months Ended						Nine Months Ended
	February 28,						February 28,
	2023			2022			2023			2022

Expected term (in years)		5			5			5			6
Volatility		90	%		117	%		116	%		77	%
Risk-free interest rate		3.58	%		1.56	%		3.11	%		1.03	%
Weighted average grant date fair value	$	24.30		$	9.43		$	7.24		$	2.56

Table of Contents

The fair values of the ESPP purchase rights granted for the nine months ended February 28, 2023 and 2022 were estimated using the following assumptions:

	Nine Months Ended			Nine Months Ended
	February 28, 2023			February 28, 2022

Expected term (in years)	0.5-2.0			0.5-2.0
Volatility	90%-203		%	101%-143		%
Risk-free interest rates	3.97%-4.12		%	0.05%-0.27		%
Weighted average grant date fair value	$	11.17		$	9.57

There were no ESPP purchase rights granted to employees for the three months ended February 28, 2023 and 2022. During the nine months ended February 28, 2023 and 2022, ESPP purchase rights of 43,000 and 103,000 were granted, respectively. Total ESPP shares issued during the nine months ended February 28, 2023 and 2022 were 109,000 and 75,000 shares, respectively. There were 499,000 ESPP shares available for issuance as of February 28, 2023.

OVERVIEW

We were founded in 1977 to develop and manufacture burn-in and test equipment for the semiconductor industry. Since our inception, we have sold more than 2,500 systems to semiconductor manufacturers, semiconductor contract assemblers and burn-in and test service companies worldwide. Our principal products currently are the FOX-XP, FOX-NP and FOX-CP wafer contact and singulated die/module parallel test and burn-in systems, WaferPak Aligner, WaferPak contactors, DiePak Loader, DiePak carriers and test fixtures.

Our net sales consist primarily of sales of systems, WaferPak Aligners and DiePak Loaders, WaferPak contactors, DiePak carriers, test fixtures, upgrades and spare parts, revenues from service contracts, and engineering development 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 and transfer of title.

CRITICAL ACCOUNTING POLICIES AND 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, product returns, bad debts, inventories, income taxes, financing obligations, warranty obligations, and long-term service contracts. 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, 2022.

There have been no material changes to our critical accounting policies and estimates during the three and nine months ended February 28, 2023 compared to those discussed in our Annual Report on Form 10-K for the fiscal year ended May 31, 2022.

THREE MONTHS ENDED FEBRUARY 28, 2023 COMPARED TO THREE MONTHS ENDED FEBRUARY 28, 2022

NET SALES. Net sales increased to $17.2 million for the three months ended February 28, 2023 from $15.3 million for the three months ended February 28, 2022, an increase of 12.6%. The increase in net sales for the three months ended February 28, 2023 was primarily due to the increases in net sales of our wafer-level products. Net sales of our wafer-level products for the three months ended February 28, 2023 were $16.8 million, and increased approximately $1.9 million from the three months ended February 28, 2022 due to stronger demand related to silicon carbide applications.

GROSS PROFIT. Gross profit increased to $8.9 million for the three months ended February 28, 2023 from $6.4 million for the three months ended February 28, 2022, an increase of 38.7%. Gross profit margin increased to 51.6% for the three months ended February 28, 2023 from 41.9% for the three months ended February 28, 2022. The increase in gross profit margin of 9.7% was primarily due to decreased direct material costs as a percentage of sales resulting in a 2.9% gross profit margin increase, decreased provision for inventory reserves resulting in a 5.5% gross profit margin increase, and manufacturing efficiencies from the increase in net sales resulting in a 1.3% gross profit margin increase.

SELLING, GENERAL AND ADMINISTRATIVE. SG&A expenses increased to $3.3 million for the three months ended February 28, 2023 from $2.6 million for the three months ended February 28, 2022, an increase of 24.4%. The increase in SG&A expenses was primarily the result of increases in headcount, bonuses, travel expenses and sales commissions.

RESEARCH AND DEVELOPMENT. R&D expenses increased to $1.8 million for the three months ended February 28, 2023 from $1.5 million for the three months ended February 28, 2022, an increase of 19.8%. The increase in R&D expenses was primarily due to increases in employment-related expenses, project expenses and outside services.

OTHER (EXPENSE) INCOME, NET. Other expense, net for the three months ended February 28, 2023 was $18,000 compared with other income, net for the three months ended February 28, 2022 of $10,000. The changes in other (expense) income, net was primarily due to losses or gains realized in connection with the fluctuation in the value of the dollar compared to foreign currencies during the referenced periods.

INCOME TAX EXPENSE. Income tax expense was $17,000 and $24,000 for the three months ended February 28, 2023 and 2022, respectively. Income tax expense was not significant due to available net operating loss and research and development credit carryforwards.

NINE MONTHS ENDED FEBRUARY 28, 2023 COMPARED TO NINE MONTHS ENDED FEBRUARY 28, 2022

NET SALES. Net sales increased to $42.7 million for the nine months ended February 28, 2023 from $30.5 million for the nine months ended February 28, 2022, an increase of 39.8%. The increase in net sales for the nine months ended February 28, 2023 was primarily due to the increases in net sales of our wafer-level products. Net sales of our wafer-level products for the nine months ended February 28, 2023 were $41.5 million, and increased approximately $12.4 million from the nine months ended February 28, 2022 due to stronger demand related to silicon carbide applications.

GROSS PROFIT. Gross profit increased to $21.3 million for the nine months ended February 28, 2023 from $13.2 million for the nine months ended February 28, 2022, an increase of 61.2%.

INTEREST INCOME (EXPENSE), NET. Interest income, net for the nine months ended February 28, 2023 was $758,000 compared with interest expense, net for the nine months ended February 28, 2022 of $9,000. The interest income for the nine months ended February 28, 2023 was from interest earned on U.S. treasury and government securities while no such investments were held during the nine months ended February 28, 2022. The interest expense for the nine months ended February 28, 2022 was from the PPP Loan that we obtained on April 23, 2020.

GAIN FROM FORGIVENESS OF PPP LOAN. On June 12, 2021, we received confirmation from the SVB that, on June 4, 2021, the Small Business Administration approved our PPP Loan forgiveness application for the entire PPP Loan balance of $1,679,000 and interest totaling $19,000. As a result, we recognized a gain of $1,698,000.

OTHER (EXPENSE) INCOME, NET. Other income, net was $1,000 and $68,000 for the nine months ended February 28, 2023 and 2022, respectively. The changes in other income, net was primarily due to gains realized in connection with the fluctuation in the value of the dollar compared to foreign currencies during the referenced periods.

INCOME TAX EXPENSE. Income tax expense was $49,000 and $81,000 for the nine months ended February 28, 2023 and 2022, respectively. Income tax expense was not significant due to available net operating loss and research and development credit carryforwards.

LIQUIDITY AND CAPITAL RESOURCES

Net cash provided by operating activities was $4.1 million and $2.3 million for the nine months ended February 28, 2023 and 2022, respectively. For the nine months ended February 28, 2023, net cash provided by operating activities was primarily the result of net income of $8.4 million, as adjusted to exclude the effect of a non-cash charge of stock-based compensation expense of $2.1 million, depreciation and amortization of $337,000 and accretion of investment discount of $305,000. Other changes in cash from operations primarily resulted from an increase in inventories of $6.8 million, a decrease in customer deposits and deferred revenue of $1.6 million, a decrease in trade and other accounts receivable of $1.4 million and an increase in accounts payable of $822,000. The increase in inventory was to support expected future shipments for customer orders. The decrease in customer deposits and deferred revenue was primarily due to the decrease in backlog of customer orders with down payments. The decrease in trade and other accounts receivable was primarily due to improvements in customer payment terms. The increase in accounts payable was primarily due to higher expenditures associated with higher revenue. For the nine months ended February 28, 2022, net cash provided by operating activities was primarily the result of net income of $3.7 million, as adjusted to exclude the effect of forgiveness of PPP loan of $1.7 million, and a non-cash charge of stock-based compensation expense of $2.2 million and depreciation and amortization of $226,000. Other changes in cash from operations primarily resulted from an increase in customer deposits and deferred revenue of $6.0 million, and increases in inventories of $5.4 million and accounts receivable of $3.5 million. The increase in customer deposits and deferred revenue was primarily due to the receipt of additional down payments from certain customers. The increase in inventory was to support expected future shipments for customer orders. The increase in accounts receivable was primarily due to the timing of revenue generated toward the end of the fiscal quarter.

Net cash used in investing activities was $25.5 million and $218,000 for the nine months ended February 28, 2023 and 2022, respectively. During the nine months ended February 28, 2023 net cash used in investing activities was due to the purchases of U.S. treasury securities of $33.2 million, partially offset by proceeds from maturities of U.S. treasury securities of $8 million, and the purchases of property and equipment of $178,000. During the nine months ended February 28, 2022 net cash used in investing activities was due to purchases of property and equipment.

Table of Contents

Financing activities provided cash of $7.1 million and $25.4 million for the nine months ended February 28, 2023 and 2022, respectively. Net cash provided by financing activities during the nine months ended February 28, 2023 was primarily due to the net proceeds from issuance of common stock from public offering net of issuance costs of $6.9 million, and the proceeds from the issuance of common stock under employee benefit plans of $2.0 million, partially offset by the shares repurchased for tax withholdings on vesting of RSUs of $1.7 million. Net cash provided by financing activities during the nine months ended February 28, 2022 was primarily due to the net proceeds from issuance of common stock from public offering net of issuance costs of $24.0 million, and the proceeds from the issuance of common stock under employee benefit plans of $3.1 million, partially offset by the shares repurchased for tax withholdings on vesting of RSUs of $369,000, and by the net payment of the line of credit of $1.4 million.

The effect of fluctuation in exchange rates decreased cash by $35,000 and $19,000 for the nine months ended February 28, 2023 and 2022, respectively. The changes were due to the fluctuation in the value of the dollar compared to foreign currencies.

As of February 28, 2023 and May 31, 2022, we had working capital of $67.2 million and $49.0 million, respectively.

We lease our manufacturing and office space under operating leases. We entered into a non-cancelable operating lease agreement for our United States manufacturing and office facilities, which was renewed in December 2022 and expires in September 2030. As of February 28, 2023 our operating lease liabilities totaled $6,392,000. Under the lease agreement, we are responsible for payments of utilities, taxes and insurance.

From time to time, we evaluate potential acquisitions of businesses, products or technologies that complement our business. If consummated, any such transactions may use a portion of our working capital, require the issuance of equity or entering into debt agreements. We have no present understandings, commitments or agreements with respect to any material acquisitions.

We anticipate that the existing cash balance and the available line of credit together with future income from operations, collections of existing accounts receivable, revenue from our existing backlog of products as of this filing date, the sale of inventory on hand, deposits and down payments against significant orders will be adequate to meet our working capital and capital equipment requirement needs over the next 12 months. Our future capital requirements will depend on many factors, including our growth rate, the timing and extent of our spending to support research and development activities, the timing and cost of establishing additional sales and marketing capabilities, the timing and cost to introduce new and enhanced products and the timing and cost to implement new manufacturing technologies. We successfully raised $25 million ATM offering in October 2021 and $7.3 million of $25 million ATM offering in February 2023; however, in the event that additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us or at all. Any additional debt financing obtained by us in the future could also involve restrictive covenants relating to our capital-raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. Additionally, if we raise additional funds through further issuances of equity, convertible debt securities or other securities convertible into equity, our existing stockholders could suffer significant dilution in their percentage ownership of the Company, and any new equity securities we issue could have rights, preferences and privileges senior to those of holders of our common stock. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to grow or support our business and to respond to business challenges could be significantly limited.

OFF-BALANCE SHEET ARRANGEMENTS

We have not entered into any off-balance sheet financing arrangements and have not established any special purpose or variable interest entities.

OVERVIEW OF CONTRACTUAL OBLIGATIONS

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 31, 2022.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS

We had no holdings of derivative financial or commodity instruments as of February 28, 2023 or May 31, 2022.

We are exposed to financial market risks, including changes in interest rates and foreign currency exchange rates. We only invest our short-term excess cash in government-backed securities with maturities of 12 months or less. We do not use any financial instruments for speculative or trading purposes. Fluctuations in interest rates would not have a material effect on our financial position, results of operations or cash flows.

A majority of our revenue and capital spending is transacted in U.S. Dollars. We also enter into transactions in other currencies, primarily Euros, New Taiwan Dollar, and Philippine Peso. Since our subsidiaries’ financial statements are based in their local currency and our condensed consolidated financial statements are based in U.S. Dollars, our subsidiaries and we recognize foreign exchange gains or losses in any period in which the value of the local currency rises or falls in relation to the U.S. Dollar. A 10% decrease in the value of the subsidiaries’ local currency as compared with the U.S. Dollar would not be expected to result in a significant change to our net income or loss. There have been no material changes in our risk exposure since the end of the last fiscal year, nor are any material changes to our risk exposure anticipated.

Item 4. CONTROLS AND PROCEDURES

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES. Our management evaluated, with the participation of our Chief Executive Officer and our Chief Financial Officer, the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures are effective to ensure that information we are required to disclose in reports that we file or submit under the Securities and Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and that such information is accumulated and communicated to management as appropriate to allow for timely decisions regarding required disclosure.

CHANGES IN INTERNAL CONTROLS OVER FINANCIAL REPORTING. There was no change in our internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, that occurred during the period covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

INHERENT LIMITATIONS OF INTERNAL CONTROLS. Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within us have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving our stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Item 1A. RISK FACTORS

Please refer to the description of the risk factors associated with our business previously disclosed in Part I, Item 1A - "Risk Factors" of our Annual Report on Form 10-K for the year ended May 31, 2022 filed with the Securities and Exchange Commission on August 26, 2022 and the following additional risk factor.

The collapse of certain U.S. banks and potentially other financial institutions may have adverse impacts on our business.

On March 10, 2023, SVB was shut down, followed on March 11, 2023 by Signature Bank and the Federal Deposit Insurance Corporation was appointed as receiver for those banks. Since that time, there have been reports of instability at other U.S. banks. On March 15, 2023, the Company filed a Current Report on Form 8-K with the SEC, disclosing its exposure to SVB and stating that the Company did not expect significant impact to its operations.

Despite the limited exposure and steps taken to date by U.S. agencies to protect depositors, the follow-on effects of the events surrounding the SVB and Signature Bank failures and pressure on other banks are unknown, and could include failures of other financial institutions to which we may encounter direct or indirect exposure. The extent of such impacts is uncertain, and there may be additional risks that we have not yet identified. We continue to monitor the situation on U.S. financial institutions and potential impact on our business.
