PART I. FINANCIAL INFORMATION

Deconsolidation of the Joint Venture ("the JV Company") effective December 2, 2021

As fully discussed in Notes 1 and 2 to the unaudited Condensed Consolidated Financial Statements provided herein, effective December 2, 2021, Alpha and Omega Semiconductor ("AOS" or the “Company”) deconsolidated the Joint Venture ("the JV Company") due to the reduction of AOS's percentage of equity interest in the JV Company to below 50%. Prior to that date, the JV Company was a majority-owned and consolidated subsidiary of the Company. On December 2, 2021, AOS’s equity ownership percentage of the JV Company decreased to below 50% as a result of a sale by the Company of its equity interest in the JV Company to a third-party investor. Also, the Company’s right to designate directors on the board of the JV Company was modified to three (3) out of seven (7) directors, instead of four (4) directors prior to the transaction. These, among other factors discussed in Note 1, resulted in a loss of control of the JV Company under generally accepted accounting principles. Accordingly, since December 2, 2021, AOS has accounted for its investment in the JV Company using the equity method of accounting.

AOS’s audited Consolidated Balance Sheet at June 30, 2021 included the JV Company’s assets and liabilities, after intercompany eliminations. However, the JV Company's assets and liabilities were not included in AOS’s unaudited Consolidated Balance Sheet at December 31, 2021 due to the deconsolidation of the JV Company on December 2, 2021.

AOS’s unaudited Condensed Consolidated Statements of Operations for the three and six months ended December 31, 2021 included the JV Company's results of operations for the period through December 1, 2021, the day immediately preceding the deconsolidation. For the three and six months ended December 31, 2020, AOS's unaudited consolidated results included the JV Company's results for the full periods presented.

Since the Company is unable to obtain accurate financial information from the JV Company in a timely manner, the Company records its share of earnings or losses of the JV Company on a one quarter lag. Therefore, the Company’s share of earnings or losses of the JV Company for the period from December 2, 2021 to December 31, 2021 has not been recorded in the Consolidated Statement of Operations for the three and six months ended December 31, 2021. Such equity earnings or losses will be recorded in the Company’s Consolidated Statement of Operations for the three and nine months ended March 31, 2022.

Joint Venture and Deconsolidation

On March 29, 2016, the Company entered into a joint venture contract (the “JV Agreement”) with two investment funds owned by the Municipality of Chongqing (the “Chongqing Funds”), pursuant to which the Company and the Chongqing Funds formed a joint venture, (the “JV Company”), for the purpose of constructing and operating a power semiconductor packaging, testing and 12-inch wafer fabrication facility (“Fab”) in the LiangJiang New Area of Chongqing, China (the “JV Transaction”). The Fab is being built in phases. As of December 1, 2021, the Company owned 50.9%, and the Chongqing Funds owned 49.1% of the equity interest in the JV Company. The Joint Venture was accounted under the provisions of the consolidation guidance since the Company had controlling financial interest until December 1, 2021.

Effective December 1, 2021, the Company entered into a share transfer agreement (the “STA”) with a third-party investor (the “Investor”), pursuant to which the Company sold to the Investor approximately 2.1% of outstanding equity interest held by the Company in the JV Company for an aggregate purchase price of RMB 108 million or approximately $16.9 million (the “Transaction”). The Transaction was closed on December 2, 2021 (the “Closing Date”). As a result of the Transaction, as of the Closing Date, the Company’s equity interest in the JV Company decreased from 50.9% to 48.8%, Also, the Company’s right to designate directors on the board of JV Company was reduced to three (3) out of seven (7) directors from four (4) directors prior to the Transaction. As a result of the Transaction, AOS no longer has a controlling financial interest in the JV Company under generally accepted accounting principles. Loss of control is deemed to have occurred when, among other things, a parent company owns less than a majority of the outstanding equity interest in the subsidiary, lacks a controlling financial interest in the subsidiary and, is unable to unilaterally control the subsidiary through other means such as having, or the ability to obtain or represent, a majority of the subsidiary’s Board of Directors. Because of these factors, as of December 2, 2021, the Company ceased having control over the JV Company. Therefore, the Company deconsolidated the financial

(Unaudited)

statements of the JV Company as of that date. Subsequently, the Company has accounted for its investment in the JV Company using the equity method of accounting.

On December 24, 2021, the Company entered into a share transfer agreement with another third-party investor, pursuant to which the Company sold to this investor 1.1% of outstanding equity interest held by the Company in the JV Company for an aggregate purchase price of RMB 60 million, or approximately $9.4 million. In addition, the JV Company adopted an employee equity incentive plan and issued an equity interest equivalent to 3.99% of the JV Company to exchange in cash. As a result, the Company owned 45.8% of the equity interest in the JV Company as of December 31, 2021.

On January 26, 2022, the JV Company completed a financing transaction pursuant to a corporate financing agreement (the “Financing Agreement”) between the JV Company and certain third-party investors (the “New Investors”). Under the Financing Agreement, the New Investors purchased newly issued equity interest of JV for a total purchase price of RMB 509 million (or approximately $80 million based on the currency exchange rate as of January 26, 2022) (the “Investment”). Immediately following the closing of the Investment, the percentage of outstanding JV equity interest beneficially owned by the Company was further reduced to 42.2% (see Note 13).

Certain Significant Risks and Uncertainties Related to Outbreak of Coronavirus Disease 2019 (“COVID-19”)

The COVID-19 pandemic has had and continues to have a negative impact on business and economic activities across the globe. As a result of the COVID-19 pandemic and the global economic downturn and changing consumer behaviors due to various restrictions imposed by governments, the Company has experienced shifting market trends, including an increasing demand in the markets for notebooks, PCs and gaming devices and decreasing demand for mobile phone and industrial products, as more consumers are staying at and working from home. While the Company has recently benefited from the increasing demand of consumer electronics and PC related products, there is no guarantee that this trend will continue, and such increasing demand may discontinue or decline as government authorities relax and terminate COVID-19 related restrictions and consumer behaviors change. Furthermore, as the COVID-19 pandemic continues and global economic downturn and high unemployment persists, consumer spending may slow down substantially, in which case the Company may experience a significant decline of customer orders for its products, including those designed for PC-related applications, and such decline will adversely affect its financial conditions and results of operations. The full extent of the future impact of the COVID-19 pandemic on the Company’s operational and financial performance is currently uncertain and will depend on many factors outside the Company’s control, including, without limitation, the timing, extent, trajectory and duration of the pandemic; the availability, distribution and effectiveness of vaccines; the spread of new variants of COVID-19; the continued or renewed imposition of protective public safety measures and government mandates; the continuing disruption of global supply chain affecting the semiconductor industry; and the impact of the pandemic on the global economy and demand for consumer products.

Use of Estimates

The preparation of the Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires the Company to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. To the extent there are material differences between these estimates and actual results, the Company's Condensed Consolidated Financial Statements will be affected. On an ongoing basis, the Company evaluates the estimates, judgments and assumptions including those related to stock rotation returns, price adjustments, allowance for doubtful accounts, inventory reserves, warranty accrual, income taxes, leases, share-based compensation, recoverability of and useful lives for property, plant and equipment and intangible assets, as well as the economic implications of the COVID-19 pandemic.

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current operating lease liabilities and long-term operating lease liabilities on the Company's Condensed Consolidated Balance Sheets. Finance leases are included in property, plant and equipment, finance lease liabilities and long-term finance leases liabilities on the Condensed Consolidated Balance Sheets.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The Company uses an estimate of its incremental borrowing rate based on the information available at the lease commencement date. The operating lease ROU assets also include any lease payments made and exclude lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. Operating lease expense is generally

ALPHA AND OMEGA SEMICONDUCTOR LIMITED

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

recognized on a straight-line basis over the lease term. Variable lease payments are expensed as incurred and are not included within the operating lease ROU asset and lease liability calculation. The Company does not record leases on the Condensed Consolidated Balance Sheet with a term of one year or less. The Company elected to combine its lease and non-lease components as a single lease component for all asset classes.

Revenue recognition

The Company determines revenue recognition through the following steps: (1) identification of the contract with a customer; (2) identification of the performance obligations in the contract; (3) determination of the transaction price; (4) allocation of the transaction price to the performance obligations in the contract; and (5) recognition of revenue when, or as, a performance obligation is satisfied. The Company recognizes product revenue at a point in time when product is shipped to the customer, net of estimated stock rotation returns and price adjustments that it expects to provide to certain distributors. The Company presents revenue net of sales taxes and any similar assessments. Our standard payment terms range from 30 to 90 days.

The Company sells its products primarily to distributors, who in turn sell the products globally to various end customers. The Company allows stock rotation returns from certain distributors. Stock rotation returns are governed by contract and are limited to a specified percentage of the monetary value of products purchased by distributors during a specified period. The Company records an allowance for stock rotation returns based on historical returns and individual distributor agreements. The Company also provides special pricing to certain distributors, primarily based on volume, to encourage resale of the Company’s products. Allowance for price adjustments is recorded against accounts receivable and the provision for stock rotation rights is included in accrued liabilities on the Condensed Consolidated Balance Sheets.

The Company’s performance obligations relate to contracts with a duration of less than one year. The Company elected to apply the practical expedient provided in ASC 606, “Revenue from Contracts with Customers”. Therefore, the Company is not required to disclose the aggregate amount of transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied at the end of the reporting period.

The Company recognizes the incremental direct costs of obtaining a contract, which consist of sales commissions, when control over the products they relate to transfers to the customer. Applying the practical expedient, the Company recognizes commissions as expense when incurred, as the amortization period of the commission asset the Company would have otherwise recognized is less than one year.

Packaging and testing services revenue is recognized at a point in time upon shipment of serviced products to the customer.

Share-based Compensation Expense

The Company maintains an equity-settled, share-based compensation plan to grant restricted share units and stock options. The Company recognizes expense related to share-based compensation awards that are ultimately expected to vest based on estimated fair values on the date of grant. The fair value of restricted share units is based on the fair value of the Company's common share on the date of grant. For restricted stock awards subject to market conditions, the fair value of each restricted stock award is estimated at the date of grant using the Monte-Carlo pricing model. The fair value of stock options is estimated on the date of grant using the Black-Scholes option valuation model. Share-based compensation expense is recognized on the accelerated attribution basis over the requisite service period of the award, which generally equals the vesting period. The Employee Share Purchase Plan (the “ESPP”) is accounted for at fair value on the date of grant using the Black-Scholes option valuation model.

Restricted Cash

As a condition of certain loan agreement, the Company is required to keep a compensating balance at the issuing bank (see Note 6). In addition, the Company maintains restricted cash in connection with cash balances temporarily restricted for regular business operations, including the possibility of a dispute with a vendor. These balances have been excluded from the Company’s cash and cash equivalents balance and are classified as restricted cash in the Company’s Condensed Consolidated Balance Sheets. As of December 31, 2021 and June 30, 2021, the amount of restricted cash was $0.3 million and $2.4 million, respectively.

Equity method investment

The Company uses the equity method of accounting when it has the ability to exercise significant influence, but not control, as determined in accordance with general accepted accounting principles, over the operating and financial policies of the investee. Effective December 2, 2021, the Company reduced its equity interest in the JV Company and experienced a loss of control of the JV Company. As a result, beginning December 2, 2021, the Company records its investment under equity method of accounting. Since the Company is unable to obtain accurate financial information from the JV Company in a timely manner, the Company records its share of earnings or losses of such affiliate on a one quarter lag. Therefore, the Company’s share of earnings or losses of the JV Company for the period from December 2, 2021 to December 31, 2021 has not been recorded in the Consolidated Statement of Operations for the three and six months ended December 31, 2021. Such equity earnings or losses will be recorded in the Company’s Consolidated Statement of Operations for the three and nine months ended March 31, 2022. The Company discloses and recognizes intervening events at the JV Company in the lag period that could materially affect our consolidated financial statements, if applicable.

The Company records its interest in the net earnings of its equity method investees, along with adjustments for unrealized profits or losses on intra-entity transactions and amortization of basis differences, within earnings or loss from equity interests in the Consolidated Statements of Operations. Profits or losses related to intra-entity sales with its equity method investees are eliminated until realized by the investor and investee. Basis differences represent differences between the cost of the investment and the underlying equity in net assets of the investment and are generally amortized over the lives of the related assets that gave rise to them. Equity method goodwill is not amortized or tested for impairment; instead the equity method investment is tested for impairment. The Company reviews for impairment whenever factors indicate that the carrying amount of the investment might not be recoverable. In such a case, the decrease in value is recognized in the period the impairment occurs in the Condensed Consolidated Statements of Operations.

Fair Value of Financial Instruments

The fair value of cash equivalents is categorized in Level 1 in the fair value hierarchy. Cash equivalents consist primarily of short-term bank deposits. The carrying values of financial instruments such as cash and cash equivalents, accounts receivable and accounts payable approximate their carrying values due to their short-term maturities. The carrying value of the Company's debt is considered a reasonable estimate of fair value which is estimated by considering the current rates available to the Company for debt of the same remaining maturities, structure, credit risk and terms of the debts.

Government Grants

The Company occasionally receives government grants that provide financial assistance for certain eligible expenditures in China. These grants include reimbursements on interest expense on bank borrowings, payroll tax credits, credit for property, plant and equipment in a particular geographical location, employment credits, as well as business expansion credits. Government grants are not recognized until there is reasonable assurance that the Company will comply with the conditions attaching to it, and that the grant will be received. The Company records such grants either as a reduction of the related expense, a reduction of the cost of the related asset, or as other income depending upon the nature of the grant. As a result of such grants, during the three and six months ended December 31, 2021, the Company reduced interest expense by $0.9 million and $0.9 million, property, plant and equipment by $0.1 million and $1.2 million, and operating expenses by $0.2 million and $0.2 million, respectively. During the three and the six months ended December 31, 2020, the Company reduced interest expense by $0.7 million and $1.5 million, property, plant and equipment by $0.1 million and $0.1 million and operating expenses by $1.7 million and $3.6 million, respectively.

Long-lived Assets

The Company evaluates its long-lived assets for impairment whenever events or changes indicate that the carrying amount of such assets may not be recoverable. Due to the COVID-19 pandemic, the Company assessed the changes in circumstances that occurred during the March and June 2020 quarters. These factors included continued operating losses, a decrease in the Company's share price in February and March of 2020, which reduced its market capitalization, expectation of lower business growth for the coming quarters, increased and prolonged economic and regulatory uncertainty in the global economies, and the expectation of higher supply chain costs and increased competition. Therefore, the Company performed a recoverability test by comparing the sum of the estimated undiscounted future cash flows of its long-lived assets to their carrying amount as of June 30, 2020. Some of the more significant assumptions used in the estimated future cash flows involve net sales, cost of goods sold, operating expenses, working capital, capital expenditures, income tax rates, long-term growth rates that appropriately reflect the risks inherent in the future cash flow stream and terminal value. The Company selected the assumptions used in the

ALPHA AND OMEGA SEMICONDUCTOR LIMITED

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

financial forecasts by referencing to historical data, supplemented by current and anticipated market conditions, estimated product growth rates and management's plans. These estimated future cash flows were consistent with those the Company uses in its internal planning. The result of the recoverability test indicated that the sum of the expected future cash flows (undiscounted and without interest charges) was greater than the carrying amount of the long-lived assets. Since this recoverability test was performed during fiscal 2020, circumstances have improved such that there are no indicators that the Company’s long-lived assets may not be recoverable.

Comprehensive Income

Comprehensive income is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. The Company's accumulated other comprehensive income consists of cumulative foreign currency translation adjustments. Total comprehensive income is presented in the Condensed Consolidated Statements of Comprehensive Income.

Recent Accounting Pronouncements

Recently Issued Accounting Standards not yet adopted

In November 2021, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance. This ASU requires business entities to make annual disclosures about transactions with a government they account for by analogizing to a grant or contribution accounting model under ASC 958-605. The ASU is effective for all entities within their scope for

financial statements issued for annual periods beginning after December 15, 2021. The Company does not expect the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.

In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which, among other things, provides guidance on how to account for contracts on an entity’s own equity. This ASU simplifies the accounting for certain financial instruments with characteristics of liabilities and equity. Specifically, the ASU eliminated the need for the Company to assess whether a contract on the entity’s own equity (1) permits settlement in unregistered shares, (2) whether counterparty rights rank higher than shareholder’s rights, and (3) whether collateral is required. In addition, the ASU requires incremental disclosure related to contracts on the entity’s own equity and clarifies the treatment of certain financial instruments accounted for under this ASU on earnings per share. For public business entities, the ASU is effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. The Company does not expect the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows.

Recently Adopted Accounting Standards

In January 2020, the FASB issued ASU No. 2020-01, “Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323, and Topic 815.” The ASU is based on a consensus of the Emerging Issues Task Force and is expected to increase comparability in accounting for these transactions. ASU 2016-01 made targeted improvements to accounting for financial instruments, including providing an entity the ability to measure certain equity securities without a readily determinable fair value at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Among other topics, the amendments clarify that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting. The adoption of ASU 2020-01 had no material impact on the Company's Consolidated Financial Statements.

In December 2019, the FASB issued ASU No. 2019-12 “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ("ASU 2019-12") by removing certain exceptions to the general principles. The Company adopted ASU 2019-12 as of July 1, 2021. ASU 2019-12 had no material impact on the Company's Consolidated Financial Statements.

2. Deconsolidation of the JV Company and Equity Method Investment in Equity Investee

On December 1, 2021 (the “Effective Date”), Alpha & Omega Semiconductor (Shanghai) Ltd. (“AOS SH”) and Agape Package Manufacturing (Shanghai) Limited (“APM SH” and, together with AOS SH, the “Sellers”), each a wholly-owned subsidiary of the Company, entered into a share transfer agreement ("STA") with a third-party investor to sell a portion of the Company's equity interest in the JV Company which consists of a power semiconductor packaging, testing and 12-inch wafer fabrication facility in Chongqing, China (the “Transaction”). The Transaction closed on December 2, 2021 (the “Closing Date”), which reduced the Company’s equity interest in the JV Company from 50.9% to 48.8%. Also, the Company’s right to designate directors on the board of JV Company was reduced to three (3) out of seven (7) directors, from four (4) directors prior to the Transaction. As a result of the Transaction and other factors, the Company no longer has a controlling financial interest in the JV Company and has determined that the JV Company was deconsolidated from the Company’s Consolidated Financial Statements effective as of the Closing Date.

In connection with the deconsolidation and in accordance with ASC 810-10-40-5, the Company recorded a gain on deconsolidation of $399.1 million during the three months ended December 31, 2021 in the Condensed Consolidated Statements of Operations. The gain on deconsolidation of the JV Company was calculated as follows:


	(in thousands)

Cash received for sales of shares in the JV Company	$	16,924
Fair value of retained equity method investment	393,124
Carrying amount of non-controlling interest	143,889
Cumulative translation adjustment removal	1,793
Carrying amount of net assets of the JV Company at December 1, 2021	(156,637)

Gain on deconsolidation of the JV Company	$	399,093

The Company retained significant influence over the operating and financial policies of the JV Company and measured the fair value of the retained investment based on their share of the fair value of the JV Company, which was calculated using the market approach based on the Transaction.

On December 24, 2021, the Company entered into a share transfer agreement with another third-party investor, pursuant to which the Company sold to this investor 1.1% of outstanding equity interest held by the Company in the JV Company. In addition, the JV Company adopted an employee equity incentive plan and issued an equity interest equivalent to 3.99% of the JV Company to exchange in cash. As a result of these two transactions, the Company owned 45.8% of the equity interest in the JV Company as of December 31, 2021. The net loss associated with these two sales of JV Company equity interest held by the Company were recorded in the three months ended December 31, 2021 as follows:


	(in thousands)
Gain on 1.1% equity interest sold	$	475
Loss on diluted equity interest due to employee equity incentive plan issued	(8,116)

Loss on changes on equity interest of the JV Company, net	$	(7,641)

The Company accounts for its investment in the JV Company as an equity method investment and reports its equity in earnings or loss of the JV Company on a three-month lag due to an inability to timely obtain financial information of the JV Company. Because the Company will record its equity in earnings or loss of the JV Company using lag reporting, there is no equity in earnings or loss of the JV Company included in the Company’s results of operations for the three and six months ended December 31, 2021. The Company plans to begin including its equity earnings or loss related to the JV Company in the three months ended March 31, 2022, at which time the Company expects to also provide summary financial information for the JV Company.

The Company recorded $29.3 million of deferred tax and $3.5 million of income tax payable associated with these transactions during the three months ended December 31, 2021.

3. Related Party Transactions

As of December 31, 2021, AOS owned 45.8% equity interest in the JV Company, which, by definition, is a related party to AOS. The JV Company supplies 12-inch wafers and provides assembly and testing services to AOS. AOS also sells 8-inch wafers to the JV Company for further assembly and testing services. Due to the right of offset of receivables and payables with the JV Company, as of December 31, 2021, AOS recorded the net amount of $25 million presented as other receivable, equity investee, in the Condensed Consolidated Balance Sheet. The purchases and sales by AOS since the December 2, 2021 deconsolidation of the JV Company for the three months ended December 31, 2021 were $15.6 million and $4.2 million, respectively.

5. Concentration of Credit Risk and Significant Customers

The Company manages its credit risk associated with exposure to distributors and direct customers on outstanding accounts receivable through the application and review of credit approvals, credit ratings and other monitoring procedures. In some instances, the Company also obtains letters of credit from certain customers.

Credit sales, which are mainly on credit terms of 30 to 60 days, are only made to customers who meet the Company's credit requirements, while sales to new customers or customers with low credit ratings are usually made on an advance payment basis. The Company considers its trade accounts receivable to be of good credit quality because its key distributors and direct customers have long-standing business relationships with the Company and the Company has not experienced any significant bad debt write-offs of accounts receivable in the past. The Company closely monitors the aging of accounts receivable from its distributors and direct customers, and regularly reviews their financial positions, where available.

covenants required. Other terms remain the same. As of December 31, 2021, the Borrower was in compliance with these covenants. As of December 31, 2021, there was no outstanding balance and the Company had unused credit of approximately $8.0 million.

Credit Facilities

On May 9, 2018 (the “Effective Date”), the JV Company entered into a lease finance agreement and a security agreement (the “Agreements”) with YinHai Leasing Company and China Import/Export Bank (the “Lenders”). Pursuant to the Agreements, the Lenders agreed to provide an aggregate of RMB 400.0 million, or $62.8 million based on the currency exchange rate between RMB and U.S. Dollar on the Effective Date, of financing to the JV Company (the “Lease Financing”). In exchange for the Lease Financing, the JV Company agreed to transfer title of its assembly and testing equipment to the Lenders, and the Lenders leased such equipment to the JV Company under a five-year lease arrangement, pursuant to which the JV Company makes quarterly lease payments to the Lenders consisting of principal and interest based on a repayment schedule mutually agreed by the parties. The interest under the Lease Financing is accrued based on the China Base Rate multiplied by 1.15, or 5.4625% on the Effective Date. Under the Agreements, at the end of the five-year lease term, the Lenders agree to sell such equipment back to the JV Company for a nominal amount (RMB 1). The JV Company’s obligations under the Lease Financing are secured by the land and building owned by the JV Company (the “Collateral”).

The Agreements contain customary representation, warranties and covenants, including restrictions on the transfer of the Collateral. The Agreements also contain customary events of default, including but not limited to, failure to make payments and breach of material terms under the Agreements.

8. Leases

The Company evaluates contracts for lease accounting at contract inception and assesses lease classification at the lease commencement date. Operating leases are included in operating lease right-of-use (“ROU”) assets, operating lease liabilities and operating lease liabilities - long-term on the Company's Condensed Consolidated Balance Sheets. Finance leases are included in property, plant and equipment, finance lease liabilities and finance lease liabilities-long-term on the Condensed Consolidated Balance Sheets. The Company recognizes a ROU asset and corresponding lease obligation liability at the lease commencement date where the lease obligation liability is measured at the present value of the minimum lease payments. As most of the leases do not provide an implicit rate, the Company uses its incremental borrowing rate at lease commencement. The Company uses an interest rate commensurate with the interest rate to borrow on a collateralized basis over a similar term with an amount equal to the lease payments. Operating leases are primarily related to offices, research and development facilities, sales and marketing facilities, and manufacturing facilities. In addition, long-term supply agreements to lease gas tank equipment and purchase industrial gases are accounted for as operating leases. Lease agreements frequently include renewal provisions and require the Company to pay real estate taxes, insurance and maintenance costs. For operating leases, the amortization of the ROU asset and the accretion of its lease obligation liability result in a single straight-line expense recognized over the lease term. The finance lease is related to the RMB 400.0 million of lease financing of the JV Company with YinHai Leasing Company and The Export-Import Bank of China. See Note 7 - Bank Borrowings for details. The Company does not record leases on the Condensed Consolidated Balance Sheets with a term of one year or less.

9. Shareholders' Equity and Share-based Compensation

Share Repurchase

In September 2017, the Board of Directors approved a repurchase program (the “Repurchase Program”) that allowed the Company to repurchase its common shares from the open market pursuant to a pre-established Rule 10b5-1 trading plan or through privately negotiated transactions up to an aggregate of $30.0 million. The amount and timing of any repurchases under the Repurchase Program depend on a number of factors, including but not limited to, the trading price, volume and availability of the Company’s common shares. Shares repurchased under this program are accounted for as treasury shares and the total cost of shares repurchased is recorded as a reduction of shareholders' equity. From time to time, treasury shares may be reissued as part of the Company’s share-based compensation programs. Gains on re-issuance of treasury stock are credited to additional paid-in capital; losses are charged to additional paid-in capital to offset the net gains, if any, from previous sales or re-issuance of treasury stock. Any remaining balance of the losses is charged to retained earnings.

During the six months ended December 31, 2021, the Company did not repurchase any shares pursuant to the Repurchase Program. Since the inception of the program, the Company repurchased an aggregate of 6,784,648 shares for a total cost of $67.3 million, at an average price of $9.92 per share, excluding fees and related expenses. No repurchased shares have been retired. Of the 6,784,648 repurchased shares, 161,895 shares with a weighted average repurchase price of $10.12 per share, were reissued at an average price of $5.16 per share pursuant to option exercises and vested restricted share units (“RSU”). As of December 31, 2021, approximately $13.4 million remained available under the Repurchase Program.

Time-based Restricted Stock Units (“TRSU”)

The following table summarizes the Company's TRSU activities for the six months ended December 31, 2021:


	Number of Restricted Stock Units	Weighted Average Grant Date Fair Value Per Share		Weighted Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value

Nonvested at December 31, 2021	1,057,959	$	23.21	1.36	$	64,069,997

Market-based Restricted Stock Units (“MSU”)

In December 2021, the Company granted 1.0 million market-based restricted stock units ("MSUs") to its certain personnel. The number of shares to be earned at the end of performance period is determined based on the Company’s achievement of specified stock prices and revenue thresholds during the performance period from January 1, 2022 to December 31, 2024 as well as the recipients remaining in continuous service with the Company through such period. The MSU vests in four equal annual installments after the end of performance period. The Company estimated the grant date fair values of its MSU with derived service periods of 4.1 to 7.1 years using a Monte-Carlo simulation model with the following assumptions: Risk-free interest rate of 1.0%, expected term of 3.1 years, expected volatility of 62.8% and dividend yield of 0% . The Company recorded approximately $0.5 million of expenses for these MSUs during the three and six months ended December 31, 2021.

During the quarter ended September 30, 2018, the Company granted 1.3 million MSUs to certain personnel. The number of shares to be earned at the end of performance period is determined based on the Company’s achievement of specified stock prices and revenue thresholds during the performance period from January 1, 2019 to December 31, 2021 as well as the recipients remaining in continuous service with the Company through such period. The MSUs vest in four equal annual installments after the end of the performance period. The Company estimated the grant date fair values of its MSUs using a Monte-Carlo simulation model. On August 31, 2020, the Compensation Committee of the Board approved a modification of the terms of MSU to (i) extend the performance period through December 31, 2022 and (ii) change the commencement date for the four-year time-based service period to January 1, 2023. The fair value of these MSUs was recalculated to reflect the change as of August 31, 2020 and the unrecognized compensation amount was adjusted to reflect the increase in fair value. The Company recorded approximately $0.4 million and

(Unaudited)

$0.8 million of expenses for MSUs during the three and six months ended December 31, 2021, respectively, and approximately $0.4 million and $0.6 million during the three and the six months ended December 31, 2020, respectively.

Performance-based Restricted Stock Units (“PRSUs”)

In March each year since year 2017, the Company granted PRSUs to certain personnel. The number of shares to be earned under the PRSUs is determined based on the level of attainment of predetermined financial goals. The PRSUs vest in four equal annual installments from the first anniversary date after the grant date if certain predetermined financial goals were met. The Company recorded approximately $1.0 million and $2.0 million of expense for these PRSUs during the three and six months ended December 31, 2021, respectively and approximately $0.4 million and $0.8 million during the three and six months ended December 31, 2020.

During the three months ended June 30, 2019, the Company announced an incentive program. Under this program, each participant’s award is denominated in stock and subject to achievement of certain objective goals within certain timelines. In June 2020, the Company believed it was most likely that predetermined goal measures would be met. Therefore, the Company reported such expenses in the other current liabilities line on the Condensed Consolidated Balance Sheets as the amount of bonus is to be settled in variable number of RSU’s at the completion of the objective goals. Such non-cash compensation expense was recorded as part of share-based compensation expense in the Condensed Consolidated Statements of Operations. As of December 31, 2021 and June 30, 2021, the Company recorded nil and $0.1 million such expenses in the other current liabilities, respectively. The Company recorded $0.2 million and $0.3 million such non-cash compensation expense during the three and six months ended December 31, 2021, respectively, and $0.8 million and $1.4 million during the three and six months ended December 31, 2020, respectively. As of December 31, 2021, the Company granted RSUs valued at $4.0 million to participants, which were fully vested due to achievement of certain objective measures.

The following table summarizes the Company’s PRSUs activities for the six months ended December 31, 2021:

As of December 31, 2021, total unrecognized compensation cost under the Company's equity plans was $65.3 million, which is expected to be recognized over a weighted-average period of 4.1 years.

10. Income Taxes

The Company recognized income tax expense of approximately $34.1 million and $0.7 million for the three months ended December 31, 2021 and 2020, respectively. The income tax expense of $34.1 million for the three months ended December 31, 2021 included a $32.8 million discrete tax expense related to the Company’s $391.5 million of income from the sale of equity interest in a joint venture and the related deconsolidation gain as the Company switches from the consolidation method of accounting to the equity method of accounting related to this investment and no longer asserts permanent reinvestment related to the Company’s investment in the joint venture. The income tax expense of $0.7 million for the three months ended December 31, 2020 included a $0.01 million discrete tax expense. Excluding the discrete income tax items ($391.5 million of income from the sale of equity interest in a joint venture and the related deconsolidation gain as well as other items), the effective tax rate for the three months ended December 31, 2021 and 2020 was 4.7% and 5.0%, respectively. The changes in the tax expense and effective tax rate between the periods resulted primarily from the Company reporting pretax book income of $419.1 million ($27.6 million of pretax book income excluding the $391.5 million of income from the sale of equity interest in a joint venture and the related deconsolidation gain) for the three months ended December 31, 2021 as compared to a pretax book income of $13.2 million for the three months ended December 31, 2020.

The Company recognized income tax expense of approximately $35.4 million and $1.7 million for the six months ended December 31, 2021 and 2020, respectively. The income tax expense of $35.4 million for the six months ended December 31, 2021 included a $32.8 million discrete tax expense related to the Company’s $391.5 million of income from the sale of equity interest in a joint venture and the related deconsolidation gain as the Company switches from the consolidation method of accounting to the equity method of accounting related to this investment and no longer asserts permanent reinvestment related to the Company’s investment in the joint venture as well as $0.1 million of other discrete income tax items. The income tax expense of $1.7 million for the six months ended December 31, 2020 included a $0.02 million discrete tax benefit. Excluding the discrete income tax items ($391.5 million of income from the sale of equity interest in a joint venture and the related deconsolidation gain as well as other discrete items), the effective tax rate for the six months ended December 31, 2021 and 2020 was 5.0% and 7.4%, respectively. The changes in the tax expense and effective tax rate between the periods resulted primarily from the Company reporting pretax book income of $441.9 million ($50.4 million of pretax book income excluding the $391.5 million of income from the sale of equity interest in a joint

venture and the related deconsolidation gain) for the six months ended December 31, 2021 as compared to a pretax book income of $23.0 million for the six months ended December 31, 2020.

The Company files its income tax returns in the United States and in various foreign jurisdictions. The tax years 2001 to 2021 remain open to examination by U.S. federal and state tax authorities. The tax years 2013 to 2021 remain open to examination by foreign tax authorities.

The Company's income tax returns are subject to examinations by the Internal Revenue Service and other tax authorities in various jurisdictions. In accordance with the guidance on the accounting for uncertainty in income taxes, the Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of its provision for income taxes. These assessments can require considerable estimates and judgments. As of December 31, 2021, the gross amount of unrecognized tax benefits was approximately $7.7 million, of which $4.8 million, if recognized, would reduce the effective income tax rate in future periods. If the Company's estimate of income tax liabilities proves to be less than the ultimate assessment, then a further charge to expense would be required. If events occur and the payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when the Company determines the liabilities are no longer necessary. The Company does not anticipate any material changes to its uncertain tax positions during the next twelve months.

“U.S. Consolidated Appropriations Act, 2021” (“CAA 2021”), Enacted December 27, 2020

On December 27, 2020, the United States enacted the Consolidated Appropriations Act, 2021, which made changes to existing U.S. tax laws. There was no material impact of the tax law changes included in the Consolidated Appropriations Act, 2021 to the Company.

“The American Rescue Plan Act of 2021”, Enacted March 11, 2021

On March 11, 2021, the United States enacted the American Rescue Plan Act of 2021, which made changes to existing U.S. tax laws. There was no material impact of the tax law changes included in the American Rescue Plan Act of 2021 to the Company.

On July 27, 2015, in Altera Corp. v. Commissioner, the U.S. Tax Court issued an opinion related to the treatment of stock-based compensation expense in an intercompany cost-sharing arrangement. In the July 2015 ruling, the Tax Court concluded that the sharing of the cost of employee stock compensation in a company’s cost-sharing arrangement was invalid under the U.S. Administrative Procedures Act. In June 2019, a panel of the Ninth Circuit of the U.S. Court of Appeals reversed this decision. In July 2019, Altera petitioned U.S. Court of Appeals for the Ninth Circuit to hold an en banc rehearing of the case. The petition was subsequently denied by the Ninth Circuit. Altera appealed the case to the U.S. Supreme Court in February 2020, but the U.S. Supreme Court declined to hear the case in June 2020, leaving intact the U.S. Court of Appeals for the Ninth Circuit’s decision. AOS has not recorded any benefit related to the Altera Corporation Tax Court decision in any period through December 2021. The Company will continue to monitor ongoing developments and potential impact to its financial statements.

11. Segment and Geographic Information

The Company is organized as, and operates in, one operating segment: the design, development and supply of power semiconductor products for computing, consumer electronics, communication and industrial applications. The chief operating decision-maker is the Chief Executive Officer. The financial information presented to the Company’s Chief Executive Officer is on a consolidated basis, accompanied by information about revenue by customer and geographic region, for purposes of evaluating financial performance and allocating resources. The Company has one business segment, and there are no segment managers who are held accountable for operations, operating results and plans for products or components below the consolidated unit level. Accordingly, the Company reports as a single operating segment.

The Company sells its products primarily to distributors in the Asia Pacific region, who in turn sell these products to end customers. Because the Company’s distributors sell their products to end customers which may have a global presence, revenue by geographical location is not necessarily representative of the geographical distribution of sales to end user markets.

The revenue by geographical location in the following tables is based on the country or region in which the products were shipped to:

12. Commitments and Contingencies

Purchase Commitments

As of December 31, 2021 and June 30, 2021, the Company had approximately $92.3 million and $81.8 million, respectively, of outstanding purchase commitments primarily for purchases of semiconductor raw materials, wafers, spare parts, packaging and testing services and others.

As of December 31, 2021 and June 30, 2021, the Company had approximately $119.6 million and $90.0 million, respectively, of capital commitments for the purchase of property and equipment.

Other Commitments

See Note 7 and Note 8 of the Notes to the Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q for descriptions of commitments including bank borrowings and leases.

Contingencies and Indemnities

The Company has in the past, and may from time to time in the future, become involved in legal proceedings arising from the normal course of business activities. The semiconductor industry is characterized by frequent claims and litigation, including claims regarding patent and other intellectual property rights as well as improper hiring practices. Irrespective of the validity of such claims, the Company could incur significant costs in the defense of such claims and suffer adverse effects on its operations.

In December 2019, the U.S. Department of Justice (“DOJ”) commenced an investigation into the Company's compliance with export control regulations relating to its business transactions with Huawei and its affiliates (“Huawei”), which were added to the “Entity List” maintained by the Department of Commerce (“DOC”) on May 16, 2019. The Company is cooperating fully with federal authorities in the investigation, including responding to requests for documents, information and interviews from DOJ in connection with the investigation. The Company has maintained an export control compliance program and has been committed to comply fully with all applicable laws and regulations. In connection with this investigation, DOC requested the Company to suspend shipments of its products to Huawei, and the Company complied with such request, and the Company has not shipped any product to Huawei after December 31, 2019. The Company is currently working with DOC to resolve this issue. Given the case is in still ongoing and neither DOJ nor DOC have provided the Company with any clear indication of the timing and schedule for the investigation, the Company cannot estimate the reasonably possible loss or range of loss that may occur. Also, the Company is unable to predict the duration, scope, result or related costs of the investigation, although the Company expects to incur additional professional fees as a result of this matter. In addition, the Company is unable to predict what, if any, further action that may be taken by the government in connection with the investigation, or what, if any, penalties, sanctions or remedial actions may be sought.

On March 19, 2020, Darryl Gray, a stockholder of the Company (the “Plaintiff”), filed a putative class action complaint in the United States District Court for the Southern District of New York (the “Gray Action”), alleging that the Company and its management members made material misstatements or omissions regarding the Company’s business and operations, including its export control practices relating to business transactions with Huawei and its affiliate. The Gray Action asserts claims under Section 10(b) of the Exchange Act against the Company, its Chief Executive Officer and Chief Financial Officer (collectively, the “Defendants”), as well as claims under Section 20(a) of the Exchange Act against the Chief Executive Officer and Chief

Financial Officer. Among other remedies, the Gray Action seeks to recover compensatory and other damages as well as attorney’s fees and costs.

On May 18, 2020, Plaintiff moved for an order appointing him as Lead Plaintiff pursuant to Section 21D of the Exchange Act and approving Glancy Prongay & Murray LLP as Lead Counsel for the putative class (the “Motion”). On July 1, 2020, the Court entered an order granting the Motion and requiring that: (i) Lead Plaintiff file an amended complaint or designate the current complaint as operative within sixty days; (ii) Defendants answer the complaint or otherwise move within sixty days of such filing or designation; (iii) Lead Plaintiff file an opposition, if any, within forty-five days; and (iv) Defendants file a reply, if any, forty-five days thereafter. On August 28, 2020, Plaintiff filed an amended complaint asserting the same claims against the Defendants, and adding the Company’s Executive Vice President of Product Line as a defendant on both claims. On October 27, 2020, the Defendants moved to dismiss the action in its entirety. Plaintiff filed his opposition on December 11, 2020 and Defendants filed their reply brief on January 25, 2021. On September 27, 2021, the Court entered an opinion and order granting Defendants’ motion and dismissing the amended complaint in its entirety. In so doing, the Court found, among other things, that Plaintiff failed adequately to allege that any of AOS’s indirect sales to Huawei were illegal, and therefore none of the Company’s statements regarding its positive performance or its efforts to contend with a difficult geopolitical climate and trade tensions could plausibly be seen as “inaccurate, incomplete, or misleading.” The Court’s order allowed Plaintiff an opportunity to file a second amended complaint by October 27, 2021, attempting to cure the various deficiencies, barring which the matter would be dismissed with prejudice. As of that date, however, no such filing was made and the Joint Stipulation and Order of Dismissal was entered on November 9, 2021, dismissing the case with prejudice and directing the Clerk of Court to close the case.

The Company is a party to a variety of agreements that it has contracted with various third parties. Pursuant to these agreements, the Company may be obligated to indemnify another party to such an agreement with respect to certain matters. Typically, these obligations arise in the context of contracts entered into by the Company, under which the Company customarily agrees to hold the other party harmless against losses arising from a breach of representations and covenants related to such matters as title to assets sold, certain intellectual property rights, specified environmental matters and certain income taxes. In these circumstances, payment by the Company is customarily conditioned on the other party making a claim pursuant to the procedures specified in the particular contract, which procedures typically allow the Company to challenge the other party's claim. Further, the Company's obligations under these agreements may be limited in time and/or amount, and in some instances, the Company may have recourse against third parties for certain payments made by it under these agreements. The Company has not historically paid or recorded any material indemnifications, and no accrual was made at December 31, 2021 and June 30, 2021.

The Company has agreed to indemnify its directors and certain employees as permitted by law and pursuant to its Bye-laws, and has entered into indemnification agreements with its directors and executive officers. The Company has not recorded a liability associated with these indemnification arrangements, as it historically has not incurred any material costs associated with such indemnification obligations. Costs associated with such indemnification obligations may be mitigated by insurance coverage that the Company maintains. However, such insurance may not cover any, or may cover only a portion of, the amounts the Company may be required to pay. In addition, the Company may not be able to acquire, maintain or renew such insurance coverage in the future under favorable terms or at all.

13. Subsequent Event

On January 26, 2022, the JV Company completed a financing transaction pursuant to a corporate financing agreement (the “Financing Agreement”) between the JV Company and certain third-party investors (the “New Investors”). Under the Financing Agreement, the New Investors purchased newly issued equity interest of JV for a total purchase price of RMB 509 million (or approximately $80 million based on the currency exchange rate as of January 26, 2022) (the “Investment”). Following the closing of the Investment, the percentage of outstanding JV equity interest beneficially owned by the Company was reduced to 42.2%.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Except for the historical information contained herein, the matters addressed in this Item 2 constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward looking statements include, but are not limited to, statements regarding future financial performance of the Company; the expected ramp up timeline of the 12-inch fab at the JV Company; the impact of government investigation and coronavirus on our financial performance; and other statements and information set forth under the heading “Factors Affecting Our Performance”. Such forward-looking statements are subject to a variety of risks and uncertainties, including those discussed below under the heading “Risk Factors” and elsewhere in this Quarterly Report on Form 10-Q, that could cause actual results to differ materially from those anticipated by the Company’s management. The Private Securities Litigation Reform Act of 1995 (the “Act”) provides certain “safe harbor” provisions for forward-looking statements. All forward-looking statements made in this Quarterly Report on Form 10-Q are made pursuant to the Act. The Company undertakes no obligation to publicly release the results of any revisions to its forward-looking statements that may be made to reflect events or circumstances after the date hereof or to reflect the occurrence of unexpected events. Unless the context otherwise requires, the words “AOS,” the “Company,” “we,” “us” and “our” refer to Alpha and Omega Semiconductor Limited and its subsidiaries.

This management’s discussion should be read in conjunction with the management’s discussion included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2021, filed with the Securities and Exchange Commission on August 30, 2021.

Overview

We are a designer, developer and global supplier of a broad portfolio of power semiconductors. Our portfolio of power semiconductors includes approximately 2,400 products, and has grown significantly with the introduction of over 160 new products in each of the fiscal years ended June 30, 2021 and 2020, respectively, and 200 new products in the fiscal year ended June 30, 2019. During the six months ended December 31, 2021, we introduced an additional 50 new products. Our teams of scientists and engineers have developed extensive intellectual property and technical knowledge that encompass major aspects of power semiconductors, which we believe enables us to introduce and develop innovative products to address the increasingly complex power requirements of advanced electronics. We have an extensive patent portfolio that consists of 874 patents and 57 patent applications in the United States as of December 31, 2021. We also have a total of 918 foreign patents, which were based primarily on our research and development efforts through December 31, 2021. We differentiate ourselves by integrating our expertise in technology, design and advanced manufacturing and packaging to optimize product performance and cost. Our portfolio of products targets high-volume applications, including personal and portable computers, graphic cards, flat panel TVs, home appliances, smart phones, battery packs, game consoles, consumer and industrial motor controls and power supplies for TVs, computers, servers and telecommunications equipment.

Our business model leverages global resources, including research and development and manufacturing in the United States and Asia. Our sales and technical support teams are localized in several growing markets. We operate an 8-inch wafer fabrication facility located in Hillsboro, Oregon, or the Oregon fab, which is critical for us to accelerate proprietary technology development, new product introduction and improve our financial performance. To meet the market demand for the more mature high volume products, we also utilize the wafer manufacturing capacity of selected third party foundries. For assembly and test, we primarily rely upon our in-house facilities in China. In addition, we utilize subcontracting partners for industry standard packages. We believe our in-house packaging and testing capability provides us with a competitive advantage in proprietary packaging technology, product quality, cost and sales cycle time.

During the fiscal quarter ended December 31, 2021, we continued our product diversification program by developing new silicon and packaging platforms to expand our serviceable available market, or SAM and offer higher performance products. Our metal-oxide-semiconductor field-effect transistors, or MOSFET, and power IC product portfolio expanded significantly. Our high performance products and deepened customer relationships with our OEM and ODM customers have contributed to the achievement of our record high quarterly revenue of $193.3 million for the three months ended December 31, 2021, a 21.7% growth compared to the same quarter last year.

On March 29, 2016, we formed a joint venture (the “JV Company”) with two investment funds owned by the Municipality of Chongqing (the “Chongqing Funds”), for the purpose of constructing and operating a power semiconductor packaging, testing and 12-inch wafer fabrication facility (“Fab”) in the LiangJiang New Area of Chongqing, China. The Fab is being built in phases. As of December 1, 2021, we owned 50.9%, and the Chongqing Funds owned 49.1% of the equity interest in the JV Company. The Joint Venture was accounted under the provisions of the consolidation guidance since we had controlling financial interest until December 1, 2021.

On December 24, 2021, we entered into a share transfer agreement with another third-party investor, pursuant to which we sold to this investor 1.1% of outstanding equity interest held by us in the JV Company for an aggregate purchase price of RMB 60 million or approximately $9.4 million. In addition, the JV Company adopted an employee equity incentive plan and issued an equity interest equivalent to 3.99% of the JV Company to exchange in cash. As a result, we owned 45.8% of the equity interest in the JV Company as of December 31, 2021.

On January 26, 2022, the JV Company completed a financing transaction pursuant to a corporate financing agreement (the “Financing Agreement”) between the JV Company and certain third-party investors (the “New Investors”). Under the Financing Agreement, the New Investors purchased newly issued equity interest of JV for a total purchase price of RMB 509 million (or approximately $80 million based on the currency exchange rate as of January 26, 2022) (the “Investment”). Following the closing of the Investment, the percentage of outstanding JV equity interest beneficially owned by the Company was reduced to 42.2%. See Note 1 and Note 2 of the Notes to the Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q for a description of deconsolidation of the JV Company and equity method of the JV Company.

We reduced our ownership of the JV Company to below 50% to increase the flexibility of the JV Company to raise capital to fund its future expansion. Following the Transaction and the successful ramp up to its Phase I target run rate in the September quarter of 2021, as planned, the JV Company intends to raise up to $200 million through private funding rounds for its Phase II expansion. In addition to immediate private funding rounds, the JV Company is also contemplating an eventual listing on the Science and Technology innovAtion boaRd, or STAR Market, of the Shanghai Stock Exchange. The Transaction assists the JV Company in meeting certain regulatory listing requirements. A potential STAR Market listing may take several years to consummate and there is no guarantee that such listing by the JV Company will be successful or will be completed in a timely manner, or at all. In addition, the JV Company will continue to provide us with significant level of foundry capacity to enable us to develop and manufacture our products.

Impact of COVID-19 Pandemic to our Business

Our business operations have been impacted by the global COVID-19 pandemic and the resulting economic downturn. Numerous governmental jurisdictions, including the States of California, Oregon and Texas in the U.S. and countries throughout the Asia Pacific region have imposed various restrictions on commercial activities, resulting in business closures, work stoppages, labor shortage, disruptions to ports, vaccine mandates and other shipping infrastructure, border closures, thereby negatively impacting our customers, suppliers, distributors, employees, offices, and the entire semiconductor ecosystem.

As a result of the COVID-19 pandemic and changing consumer behaviors due to various government restrictions and the growing trend to provide remote-working options by employers, , we have experienced shifting market trends, including an increasing demand in markets for notebooks, PCs, gaming devices and other products. While we have benefited from the increasing demand for PC related products, there is no guarantee that this trend will continue, and such increasing demand may discontinue or decline if government authorities relax or terminate COVID-19 related restrictions and consumer behaviors change in response to the reopening of certain economic activities. In an effort to protect the health and safety of our employees and to comply with various government and regulatory guidelines, we also took proactive actions to adopt policies and protocols at our locations around the world, including social distancing guidelines, vaccine and testing protocols,

Since the start of the second quarter of calendar year 2021, there have been increasing availability and administration of vaccines against COVID-19, as well as an easing of restrictions on social, business, travel, and government activities and

functions, and a gradual resumption of economic activities and consumer spending in our industries. On the other hand, infection rates continue to fluctuate in various regions and new strains of the virus remain a risk, including the recent surge of COVID-19 cases and hospitalization due to the spread of Omicron variants. In addition, there are ongoing global impacts resulting from the pandemic, including disruption of the product supply chains, shortages of semiconductor components, and delays in shipments, product development, and product launches and rising inflation rates. The full extent of the future impact of the COVID-19 pandemic on our operational and financial performance is uncertain and will depend on many factors outside our control, including, without limitation, the timing, extent, trajectory and duration of the pandemic; the availability, distribution and effectiveness of vaccines; the spread of new variants of COVID-19; the continued and renewed imposition of protective public safety measures; the disruption of global supply chain; and the impact of the pandemic on the global economy and demand for consumer products. Although we are unable to predict the full impact and duration of the COVID-19 pandemic on our business, we are actively managing our business operations and financial expenditures in response to continued uncertainty.

Other Factors affecting our performance

In addition to the COVID-19 pandemic and related events as described above, our performance is affected by several key factors, including the following:

The global, regional economic and PC market conditions: Because our products primarily serve consumer electronic applications, any significant change in global and regional economic conditions could materially affect our revenue and results of operations. A significant amount of our revenue is derived from sales of products in the personal computing (“PC”) markets, such as notebooks, motherboards and notebook battery packs, therefore a substantial decline or downturn in the PC market could have a material adverse effect on our revenue and results of operations. The PC markets have experienced a modest global decline in recent years due to continued growth of demand in tablets and smart phones, worldwide economic conditions and the industry inventory correction which had and may continue to have a material impact on the demand for our products. However, we recently have experienced a significant increase of demand in PC market due to the impact of the COVID-19 pandemic and resulting shift in market trend and consumer behaviors. We cannot predict whether and how long this trend will continue due to the uncertainty and unpredictability of COVID-19 pandemic. A decline of the PC market may have a negative impact on our revenue, factory utilization, gross margin, our ability to resell excess inventory, and other performance measures. We have executed and continue to execute strategies to diversify our product portfolio, penetrate other market segments, including the consumer, communications and industrial markets, and improve gross margins and profit by implementing cost control measures. While making efforts to reduce our reliance on the computing market, we continue to support our computing business and capitalize on the opportunities in this market with a more focused and competitive PC product strategy to gain market share.

Manufacturing costs and capacity availability: Our gross margin is affected by a number of factors including our manufacturing costs, utilization of our manufacturing facilities, the product mixes of our sales, pricing of wafers from third party foundries and pricing of semiconductor raw materials. Capacity utilization affects our gross margin because we have certain fixed costs at our Shanghai facilities and our Oregon fab. If we are unable to utilize our manufacturing facilities at a desired level, our gross margin may be adversely affected. In addition, from time to time, we may experience wafer capacity constraints, particularly at third party foundries, that may prevent us from meeting fully the demand of our customers. For example, the recent global shortage of semiconductor manufacturing capacity has provided us with both challenges and opportunities in the market, and highlighted the importance of maintaining sufficient and independent in-house manufacturing capabilities to meet increasing customer demands. While we can mitigate these constraints by increasing and re-allocating capacity at our own fab, we may not be able to do so quickly or at sufficient level, which could adversely affect our financial conditions and results of operations. In addition, we recently commenced a plan to enhance the manufacturing capability and capacity of our Oregon fab by investing in new equipment and expanding our factory facilities, which we expect will have a positive impact on our future new product development and revenue, particularly during the period of global shortage of capacity. We also rely substantially on the JV Company to provide foundry capacity to manufacture our products, therefore it is critical that we maintain continuous access to such capacity, which may not be available at sufficient level or at a pricing terms favorable to us because of lack of control over the JV Company’s operation. As a result of recent sales of our JV equity interests and issuance of additional equity interests by the JV Company to third-party investors in financing transactions, our equity interest in the JV Company was reduced to 42.2%, which reduced our control and influence over the JV Company. While we continue to maintain a business relationship with the JV Company to ensure uninterrupted supply of manufacturing capacity, and we are currently negotiating a foundry agreement for the JV Company to provide guarantee level of capacity, the JV Company may take actions or make decisions that adversely impact our ability to access required capacity, and our lack of control and influence may prevent us from eliminating or mitigating such risk.

Erosion and fluctuation of average selling price: Erosion of average selling prices of established products is typical in our industry. Consistent with this historical trend, we expect our average selling prices of existing products to decline in the

future. However, in the normal course of business, we seek to offset the effect of declining average selling price by introducing new and higher value products, expanding existing products for new applications and new customers and reducing the manufacturing cost of existing products. These strategies may cause the average selling price of our products to fluctuate significantly from time to time, thereby affecting our financial performance and profitability.

Product introductions and customers’ product requirements: Our success depends on our ability to introduce products on a timely basis that meet or are compatible with our customers' specifications and performance requirements. Both factors, timeliness of product introductions and conformance to customers' requirements, are equally important in securing design wins with our customers. As we accelerate the development of new technology platforms, we expect to increase the pace at which we introduce new products and seek and acquire design wins. If we were to fail to introduce new products on a timely basis that meet customers’ specifications and performance requirements, particularly those products with major OEM customers, and continue to expand our serviceable markets, then we would lose market share and our financial performance would be adversely affected.

Distributor ordering patterns, customer demand and seasonality: Our distributors place purchase orders with us based on their forecasts of end customer demand, and this demand may vary significantly depending on the sales outlook and market and economic conditions of end customers. Because these forecasts may not be accurate, channel inventory held at our distributors may fluctuate significantly, which in turn may prompt distributors to make significant adjustments to their purchase orders placed with us. As a result, our revenue and operating results may fluctuate significantly from quarter to quarter. In addition, because our products are used in consumer electronics products, our revenue is subject to seasonality. Our sales seasonality is affected by numerous factors, including global and regional economic conditions as well as the PC market conditions, revenue generated from new products, changes in distributor ordering patterns in response to channel inventory adjustments and end customer demand for our products and fluctuations in consumer purchase patterns prior to major holiday seasons. In recent periods, broad fluctuations in the semiconductor markets and the global and regional economic conditions, in particular the decline of the PC market conditions, have had a more significant impact on our results of operations than seasonality. Furthermore, our revenue may be impacted by the level of demand from our major customers due to factors outside of our control. If these major customers experience significant decline in the demand of their products, encounter difficulties or defects in their products, or otherwise fail to execute their sales and marketing strategies successfully, it may adversely affect our revenue and results of operations.

Regulatory Matters: As previously disclosed, the DOJ commenced an investigation into our compliance with export control regulations relating to business transactions with Huawei, which were added to the “Entity List” by the DOC in May 2019. We continue to cooperate fully with federal authorities in the investigation. We have continued to respond to inquiries and requests from DOJ for documents and information relating to the investigation, and the matter is currently pending at DOJ. However, DOJ and DOC have not provided us any clear or definitive response regarding the timeline of the investigation and potential resolutions or outcome. In the meantime, we continue to incur significant costs and expenses, including legal and professional fees, in connection with the government investigation, which may reduce our profitability and operating margin.

Principal line items of statements of operations

The following describes the principal line items set forth in our Condensed Consolidated Statements of Operations:

Revenue

We generate revenue primarily from the sale of power semiconductors, consisting of power discretes and power ICs. Historically, a majority of our revenue has been derived from power discrete products. Because our products typically have three-year to five-year life cycles, the rate of new product introduction is an important driver of revenue growth over time. We believe that expanding the breadth of our product portfolio is important to our business prospects, because it provides us with an opportunity to increase our total bill-of-materials within an electronic system and to address the power requirements of additional electronic systems. In addition, a small percentage of our total revenue is generated by providing packaging and testing services to third parties through one of our subsidiaries.

Our product revenue is reported net of the effect of the estimated stock rotation returns and price adjustments that we expect to provide to our distributors. Stock rotation returns are governed by contract and are limited to a specified percentage of the monetary value of products purchased by the distributor during a specified period. At our discretion or upon our direct negotiations with the original design manufacturers (“ODMs”) or original equipment manufacturers (“OEMs”), we may elect to grant special pricing that is below the prices at which we sold our products to the distributors. In these situations, we will grant price adjustments to the distributors reflecting such special pricing. We estimate the price adjustments for inventory at the distributors based on factors such as distributor inventory levels, pre-approved future distributor selling prices, distributor margins and demand for our products.

Cost of goods sold

Our cost of goods sold primarily consists of costs associated with semiconductor wafers, packaging and testing, personnel, including share-based compensation expense, overhead attributable to manufacturing, operations and procurement, and costs associated with yield improvements, capacity utilization, warranty and valuation of inventories. As the volume of sales increases, we expect cost of goods sold to increase. While our utilization rates cannot be immune to the market conditions, our goal is to make them less vulnerable to market fluctuations. We believe our market diversification strategy and product growth will drive higher volume of manufacturing which will improve our factory utilization rates and gross margin in the long run.

Operating expenses

Our operating expenses consist of research and development, selling, general and administrative expenses and impairment of long-lived assets. We expect our operating expenses as a percentage of revenue to fluctuate from period to period as we continue to exercise cost control measures in response to the declining PC market as well as align our operating expenses to the revenue level.

Research and development expenses. Our research and development expenses consist primarily of salaries, bonuses, benefits, share-based compensation expense, expenses associated with new product prototypes, travel expenses, fees for engineering services provided by outside contractors and consultants, amortization of software and design tools, depreciation of equipment and overhead costs. We continue to invest in developing new technologies and products utilizing our own fabrication and packaging facilities as it is critical to our long-term success. We also evaluate appropriate investment levels and stay focused on new product introductions to improve our competitiveness. We expect that our research and development expenses will fluctuate from time to time.

Selling, general and administrative expenses. Our selling, general and administrative expenses consist primarily of salaries, bonuses, benefits, share-based compensation expense, product promotion costs, occupancy costs, travel expenses, expenses related to sales and marketing activities, amortization of software, depreciation of equipment, maintenance costs and other expenses for general and administrative functions as well as costs for outside professional services, including legal, audit and accounting services. We expect our selling, general and administrative expenses to fluctuate in the near future as we continue to exercise cost control measures.

Income tax expense

We are subject to income taxes in various jurisdictions. Significant judgment and estimates are required in determining our worldwide income tax expense. The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax regulations of different jurisdictions globally. We establish accruals for potential liabilities and contingencies based on a more likely than not threshold to the recognition and de-recognition of uncertain tax positions. If the recognition threshold is met, the applicable accounting guidance permits us to recognize a tax benefit measured at the largest amount of tax benefit that is more likely than not to be realized upon settlement with a taxing authority. If the actual tax outcome of such exposures is different from the amounts that were initially recorded, the differences will impact the income tax and deferred tax provisions in the period in which such determination is made. Changes in the location of taxable income (loss) could result in significant changes in our income tax expense.

We record a valuation allowance against deferred tax assets if it is more likely than not that a portion of the deferred tax assets will not be realized, based on historical profitability and our estimate of future taxable income in a particular jurisdiction. Our judgments regarding future taxable income may change due to changes in market conditions, changes in tax laws, tax planning strategies or other factors. If our assumptions and consequently our estimates change in the future, the deferred tax assets may increase or decrease, resulting in corresponding changes in income tax expense. Our effective tax rate is highly dependent upon the geographic distribution of our worldwide profits or losses, the tax laws and regulations in each geographical region where we have operations, the availability of tax credits and carry-forwards and the effectiveness of our tax planning strategies.

U.S. Tax Cuts and Jobs Act, Enacted December 22, 2017

On December 22, 2017, the United States enacted tax reform legislation through the Tax Cuts and Jobs Act (“the Tax Act”), which significantly changes the existing U.S. tax laws, including, but not limited to, (1) a reduction in the corporate tax rate from 35% to 21%, (2) a shift from a worldwide tax system to a territorial system, (3) eliminating the corporate alternative minimum tax (AMT) and changing how existing AMT credits can be realized, (4) bonus depreciation that will allow for full expensing of qualified property, (5) creating a new limitation on deductible interest expense and (6) changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017.

The company is not currently subject to the Base Erosion and Anti-Abuse ( BEAT) tax , which is a tax imposed on certain entities who make payments to their non US affiliates, where such payments reduce the US tax base . The BEAT tax is imposed at a rate of 10% on Adjusted Taxable Income, excluding certain payments to foreign related entities. It is an incremental tax over and above the corporate income tax and is recorded as a period cost. It is

possible that this tax could be applicable in future periods, which would cause an increase to the effective tax rate and cash taxes.

“U.S. Consolidated Appropriations Act, 2021” (“CAA 2021”), Enacted December 27, 2020

“The American Rescue Plan Act of 2021”, Enacted March 11, 2021

Interest expense and other income (loss), net decreased by $0.3 million during the three months ended December 31, 2021 as compared to the same quarter last year was primarily due to a $1.1 million decrease in interest expenses as a result of higher interest refund from the Chinese government in the JV Company and one month less interest expense in the JV Company due to deconsolidation during the current quarter, offset by $0.8 million increase in foreign currency exchange loss as a result of the depreciation of RMB against USD.

Interest expense and other income (loss), net increased by $1.3 million during the six months ended December 31, 2021 as compared to the same period last year was primarily due to a $1.8 million increase in foreign currency exchange loss as a result of the depreciation of RMB against USD, offset by a $0.5 million decrease in interest expenses as a result of one month less interest expense in the JV Company due to deconsolidation.

Gain on deconsolidation of the JV Company

Effective December 1, 2021, we entered into a share transfer agreement (the “STA”) with a third-party investor (the “Investor”), pursuant to which we sold to the Investor approximately 2.1% of outstanding equity interest held by us in the JV Company for an aggregate purchase price of RMB 108 million or approximately $16.9 million (the “Transaction”). The STA contained customary representations, warranties and covenants. The Transaction was closed on December 2, 2021 (the “Closing Date”). As a result of the Transaction, as of the Closing Date, our equity interest in the JV Company decreased from 50.9% to 48.8%, Also, our right to designate directors on the board of JV Company was reduced to three (3) out of seven (7) directors, from four (4) directors prior to the Transaction. We no longer have a controlling financial interest in the JV Company under generally accepted accounting principles. Loss of control is deemed to have occurred when, among other things, a parent company owns less than a majority of the outstanding common stock in the subsidiary, lacks a controlling financial interest in the subsidiary and, is unable to unilaterally control the subsidiary through other means such as having, or the ability to obtain, a majority of the subsidiary’s Board of Directors. All of these loss of control factors were present for us as of December 2, 2021. Accordingly, since December 2, 2021, AOS has accounted for its investment in the JV Company using the equity method of accounting. On December 24, 2021, we entered into a STA with another third-party investor, pursuant to which we sold to this investor 1.1% of outstanding equity interest held by us in the JV Company for an aggregate purchase price of RMB 60 million or approximately $9.4 million. In addition, the JV Company adopted an employee equity incentive plan and issued an equity interest equivalent to 3.99% of the JV Company to exchange in cash. As a result, the Company owned 45.8% of the equity interest in the JV Company as of December 31, 2021. On January 26, 2022, the JV Company completed a financing transaction pursuant to a corporate financing agreement (the “Financing Agreement”) between the JV Company and certain third-party investors (the “New Investors”). Under the Financing Agreement, the New Investors purchased newly issued equity interest of JV for a total purchase price of RMB 509 million (or approximately $80 million based on the currency exchange rate as of January 26, 2022) (the “Investment”). Following the closing of the Investment, the percentage of outstanding JV equity interest beneficially owned by us was reduced to 42.2%.

During the three months ended December 31, 2021, we recorded a $399.1 million of gain on deconsolidation of the JV Company and a $7.6 million of net loss on changes of equity interest in the JV Company.

The income tax expense of $0.7 million for the three months ended December 31, 2020 included a $0.01 million discrete tax expense. Excluding the discrete income tax items ($391.5 million of income from the sale of equity interest in a joint venture and the related deconsolidation gain as well as other discrete items), the effective tax rate for the three months ended December 31, 2021 and 2020 was 4.7% and 5.0%, respectively. The changes in the tax expense and effective tax rate between the periods resulted primarily from the Company reporting pretax book income of $419.1 million ($27.6 million of pretax book income excluding the $391.5 million of income from the sale of equity interest in a joint venture and the related deconsolidation gain) for the three months ended December 31, 2021 as compared to a pretax book income of $13.2 million for the three months ended December 31, 2020.

The Company recognized income tax expense of approximately $35.4 million and $1.7 million for the six months ended December 31, 2021 and 2020, respectively. The income tax expense of $35.4 million for the six months ended December 31, 2021 included a $32.8 million discrete tax expense related to the Company’s $391.5 million of income from the sale of equity interest in a joint venture and the related deconsolidation gain as the Company switches from the consolidation method of accounting to the equity method of accounting related to this investment and no longer asserts permanent reinvestment related to the Company’s investment in the joint venture as well as $0.1 million for other discrete income tax items.

The changes in the tax expense and effective tax rate between the periods resulted primarily from the Company reporting pretax book income of $441.9 million ($50.4 million of pretax book income excluding the $391.5 million of income from the sale of equity interest in a joint venture and the related deconsolidation gain) for the six months ended December 31, 2021 as compared to a pretax book income of $23.0 million for the six months ended December 31, 2020.

Liquidity and Capital Resources

Our principal need for liquidity and capital resources is to maintain sufficient working capital to support our operations and to invest adequate capital expenditures to grow our business. To date, we finance our operations and capital expenditures primarily through funds generated from operations and borrowings under our term loans, financing lease and other debt agreements.

On August 18, 2021, Jireh entered into a term loan agreement with a financial institution (the "Bank") in an amount up to $45.0 million for the purpose of expanding and upgrading the Company’s fabrication facility located in Oregon. The obligation under the loan agreement is secured by substantially all assets of Jireh and guaranteed by the Company. The agreement has a 5.5 year term and matures on February 16, 2027. Jireh is required to make consecutive quarterly payments of principal and interest. The loan accrues interest based on adjusted LIBOR plus the applicable margin based on the outstanding balance of the loan. This agreement contains customary restrictive covenants and includes certain financial covenants that require the Company to maintain. As of December 31, 2021, there was no outstanding balance under the loan.

eligible accounts receivable of the Borrower with a maximum amount of $30.0 million. The interest rate is based on one month London Interbank Offered Rate (“LIBOR”) plus 1.75% per annum. The Company is the guarantor for this agreement. The Company is accounting for this transaction as a secured borrowing under the Transfers and Servicing of Financial Assets guidance. In addition, any cash held in the restricted bank account controlled by HSBC has a legal right of offset against the borrowing. This agreement, with certain financial covenants required, has no expiration date. On August 11, 2021, the Borrower signed an agreement with HSBC to decrease the borrowing maximum amount to $8.0 million with certain financial covenants required. Other terms remain the same. As of December 31, 2021, the Borrower was in compliance with these covenants. As of December 31, 2021, there was no outstanding balance and the Company had unused credit of approximately $8.0 million.

In September 2017, the Board of Directors approved a repurchase program (the “Repurchase Program”) that allowed us to repurchase our common shares from the open market pursuant to a pre-established Rule 10b5-1 trading plan or through privately negotiated transactions up to an aggregate of $30.0 million. The amount and timing of any repurchases under the Repurchase Program depend on a number of factors, including but not limited to, the trading price, volume and availability of our common shares. Shares repurchased under this program are accounted for as treasury shares and the total cost of shares repurchased is recorded as a reduction of shareholders’ equity. We did not repurchase any shares pursuant to the Repurchase Plan during the six months ended December 31, 2021. Since the inception of the program, we repurchased an aggregate of 6,784,648 shares for a total cost of $67.3 million, at an average price of $9.92 per share, excluding fees and related expenses. As of December 31, 2021, of the 6,784,648 repurchased shares, 161,895 shares with a weighted average repurchase price of $10.12 per share, were reissued at an average price of $5.16 per share pursuant to option exercises and vested restricted share units. We had $13.4 million remained available under the Repurchase Program as of December 31, 2021.

We believe that our current cash and cash equivalents and cash flows from operations will be sufficient to meet our anticipated cash needs, including working capital and capital expenditures, for at least the next twelve months. In the long-term, we may require additional capital due to changing business conditions or other future developments, including any investments or acquisitions we may decide to pursue. If our cash is insufficient to meet our needs, we may seek to raise capital through equity or debt financing. The sale of additional equity securities could result in dilution to our shareholders. The incurrence of indebtedness would result in increased debt service obligations and may include operating and financial covenants that would restrict our operations. We cannot be certain that any financing will be available in the amounts we need or on terms acceptable to us, if at all.

JV Company Financing Transactions

From time to time the JV Company entered into financing and loan agreements with banks and other third parties to fund capital expenditures and other operational expenses in connection with the constructions and ramp-up of the manufacturing facility in Chongqing. Prior to the deconsolidation on December 2, 2021, the JV Company incurred debt through its own financing agreements, and our parent company and other subsidiaries were not parties to these agreements and do not provide any guarantee or security for JV Company’s debt, nor do we have direct access to any cash proceeds borrowed from such loan agreements. Following the deconsolidation, the JV Company’s debts and liabilities were removed from our Condensed Consolidated Balance Sheet as of December 31, 2021.

on April 26, 2020). The obligation under the loan agreement is secured by certain assets of the JV Company. The obligation under the loan agreement is secured by certain assets of the JV Company with a carrying value of $104.1 million as of December 1, 2021. The JV Company is required to make consecutive semi-annual payments of principal until December 8, 2024. Interest payments are due on March 20, June 20, September 20 and December 20 of each year based on the LPR plus 1.3%. The JV Company drew down RMB 250.0 million (approximately $35.3 million based on the currency exchange rate between RMB and U.S. Dollar on June 30, 2020) in April 2020. As of December 1, 2021, the outstanding balance of the loan was $31.3 million. On December 2, 2021, the JV Company was deconsolidated from the Company, thus the loan was no longer on the Company’s Condensed Consolidated Balance Sheet as of December 31, 2021.

On November 13, 2020, the JV Company entered into a one-year loan agreement with China Merchant Bank in China. The JV Company can borrow up to RMB 50.0 million, or $7.6 million, based on the currency exchange rate between RMB and U.S. Dollar on November 13, 2020. The loan's interest rates are based on the China one-year loan prime rate (“LPR”) plus 1.4% per annum. Interest payments are due quarterly with the entire principal due not later than November 19, 2021. During the three months ended December 31, 2020, the JV Company borrowed RMB 50.0 million, or $7.6 million, at an interest rate of 5.25% per annum. As of December 1, 2021, there was was no outstanding balance under the loan. On December 2, 2021, the JV Company was deconsolidated from the Company, thus the loan was no longer on the Company’s Condensed Consolidated Balance Sheet as of December 31, 2021.

Cash, cash equivalents and restricted cash

As of December 31, 2021 and June 30, 2021, we had $269.6 million and $204.8 million of cash, cash equivalents and restricted cash, respectively. Our cash, cash equivalents and restricted cash primarily consist of cash on hand, restricted cash, and short-term bank deposits with original maturities of three months or less. Of the $269.6 million and $204.8 million cash, cash equivalents and restricted cash, $223.6 million and $134.6 million, respectively, are deposited with financial institutions outside the United States.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have been no material changes in the market risks previously disclosed in Part II, Item 7A, "Quantitative and Qualitative Disclosures About Market Risk," of our Annual Report on Form 10-K for the year ended June 30, 2021, filed with the SEC on August 30, 2021.

ITEM 4. CONTROLS AND PROCEDURES

Management's Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, (the “Exchange Act”)), as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of December 31, 2021 have been designed and are functioning effectively to provide reasonable assurance that the information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the six months ended December 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitation on Effectiveness of Controls

While our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance that their respective objectives will be met, we do not expect that our disclosure controls and procedures or our internal control over financial reporting are or will be capable of preventing or detecting all errors and all fraud. Any control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

As previously disclosed, the DOJ commenced an investigation into the Company’s compliance with export control regulations relating to its business transactions with Huawei and its affiliates (“Huawei”), which were added to the “Entity List” by the DOC in May 2019. The Company is cooperating fully with federal authorities in the investigation. The Company has continued to respond to inquiries and requests from DOJ for documents and information relating to the investigation, and the matter is currently pending at DOJ, and DOJ has not provided the Company with any specific timeline or indication as to when the investigation will be concluded or resolved. In connection with this investigation, DOC previously requested the Company to suspend shipments of its products to Huawei. The Company complied with such request, and the Company has not shipped any product to Huawei after December 31, 2019. The Company continues to work with DOC to resolve this issue and requested DOC to grant permission to reinstate the Company’s shipments to Huawei. As part of this process and in response to DOC’s request, the Company provided certain documents and materials relating to the Company’s supply chain and shipment process to DOC, and DOC is currently reviewing this matter. DOC has not informed the Company of any specific timeline or schedule under which DOC will provide a response to the Company’s request.

On March 19, 2020, Darryl Gray, a stockholder of the Company (the “Plaintiff”), filed a putative class action complaint in the United States District Court for the Southern District of New York (the “Gray Action”), alleging that the Company and its management members made material misstatements or omissions regarding the Company’s business and operations, including its export control practices relating to business transactions with Huawei and its affiliates. The Gray Action asserts claims under Section 10(b) of the Exchange Act against the Company, its Chief Executive Officer and Chief Financial Officer (collectively, the Defendants”), as well as claims under Section 20(a) of the Exchange Act against the Chief Executive Officer and Chief Financial Officer. Among other remedies, the Gray Action seeks to recover compensatory and other damages as well as attorney’s fees and costs.

On May 18, 2020, Plaintiff moved for an order appointing him as Lead Plaintiff pursuant to Section 21D of the Exchange Act and approving Glancy Prongay & Murray LLP as Lead Counsel for the putative class (the “Motion”). On July 1, 2020, the Court entered an order granting the Motion and requiring that: (i) Lead Plaintiff file an amended complaint or designate the current complaint as operative within sixty days; (ii) Defendants answer the complaint or otherwise move within sixty days of such filing or designation; (iii) Lead Plaintiff file an opposition, if any, within 45 days; and (iv) Defendants file a reply, if any, forty-five days thereafter. On August 28, 2020, Plaintiff filed an amended complaint asserting the same claims against the Defendants, and adding the Company’s Executive Vice President of Product Line as a defendant on both claims. On October 27, 2020, the Defendants moved to dismiss the action in its entirety. Plaintiff filed his opposition on December 11, 2020 and Defendants filed their reply brief on January 25, 2021. On September 27, 2021, the Court entered an opinion and order granting Defendants’ motion and dismissing the amended complaint in its entirety. In so doing, the Court found, among other things, that Plaintiff failed adequately to allege that any of AOS’s indirect sales to Huawei were illegal, and therefore none of the Company’s statements regarding its positive performance or its efforts to contend with a difficult geopolitical climate and trade tensions could plausibly be seen as “inaccurate, incomplete, or misleading.” The Court’s order allowed Plaintiff an opportunity to file a second amended complaint by October 27, 2021. As of that date, however, no such filing was made and the a Joint Stipulation and Order of Dismissal was entered on November 9, 2021, dismissing the case with prejudice and directing the Clerk of Court to close the case.

We have in the past, and may from time to time in the future, become involved in legal proceedings arising from the normal course of business activities. The semiconductor industry is characterized by frequent claims and litigation, including claims regarding patent and other intellectual property rights as well as improper hiring practices. Irrespective of the validity of such claims, we could incur significant costs in the defense thereof or could suffer adverse effects on its operations.

ITEM 1A. RISK FACTORS

Item 1A of Part I of our Annual Report on Form 10-K for the year ended June 30, 2020, filed with the SEC on August 30, 2021, contains risk factors identified by the Company. Except as noted below, there have been no material changes to the risk factors we previously disclosed in our filings with the SEC. Our operations could also be affected by additional factors that are not presently known to us or by factors that we currently consider immaterial to our business.

Our lack of control over the JV Company may adversely affect our operations.

The JV Company consists of a power semiconductor packaging, testing and 12-inch wafer fabrication facility in Chongqing. The JV Company is our subcontractor, we rely and expect to continue to rely substantially on the JV Company to provide us with foundry capacity to develop and manufacture our products and to enhance our market position in China. Since the formation of the JV Company, we have retained control over the business operation of the JV Company through our majority equity ownership and board representation. In December 2021, we relinquished control over the JV Company through a series of transactions, including the sale of a portion of our equity interests in the JV Company and issuance of additional equity interests by the JV Company to raise capital. As a result of these transactions, we currently own approximately 42.2% of outstanding equity interest in the JV Company and has the right to designate three (3) out of seven (7) directors, instead of four (4) directors prior to such transaction. The reduction of our equity ownership of the JV Company is part of a plan to enable the JV Company to raise capital more easily and to facilitate a future public listing on the Science and Technology innovAtion boaRd, or STAR Market, of the Shanghai Stock Exchange (the “China IPO”). Such reduction also caused the deconsolidation of the JV Company’s financial statements from our Consolidated Financial Statements.

Because we no longer have a controlling interest in the JV Company, the JV Company is operating and will continue to operate more independently, and our influence on all aspects of the JV Company’s business operations will be diminished. Accordingly, we might not be able to prevent the JV Company from taking actions adverse to our interests. For example, while we remain a major customer of the JV Company, the JV Company may decide to enter into business relationships with other customers and allocate foundry capacities to such customers, which may prevent us from securing a desirable or sufficient level of manufacturing capacity for our products. Even if the JV Company agrees to continue allocating sufficient manufacturing capacity to us, we may not be able to negotiate or obtain favorable pricing or service terms, which may increase our expenses and adversely affect our results of operations.

Our lack of control over the JV Company may also make it more difficult for us to execute our broader business strategies in China, including our R&D, sales and marketing, product innovation efforts and protection of intellectual property rights, because the JV Company may decide not to cooperate with us in these matters. In addition, while we expect to achieve financial return for our investment in the JV Company as a result of the China IPO, the China IPO process is complex, time-consuming and subject to a number of risks and there is no guarantee that the China IPO will be completed in a timely manner, or at all, and the JV Company’s failure to close the China IPO will negatively affect our investment in the JV Company.

In order to fund its capital expenditures and cost of operation, the JV Company has incurred a significant amount of indebtedness from third-party lenders under several loan and lease financing agreements, some of which are secured by substantially all of the assets of the JV Company. If the JV Company is not able to generate sufficient cash flow to make payments under these loans, the JV Company may be in default, which will adversely affect its ability to continue operations and provide foundry services to us. In addition, the JV Company requires additional funding to continue its operations and to refinance its existing indebtedness. There is no guarantee that the JV Company will be able to obtain financing on favorable terms, or at all, and any such failure may negatively impact our ability to access its wafer manufacturing capacity.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

In September 2017, the Board of Directors approved a repurchase program (the “Repurchase Program”) that allowed us to repurchase our common shares from the open market pursuant to a pre-established Rule 10b5-1 trading plan or through privately negotiated transactions up to an aggregate of $30.0 million. The amount and timing of any repurchases under the Repurchase Program depend on a number of factors, including but not limited to, the trading price, volume and availability of our common shares. There is no guarantee that such repurchases under the Repurchase Program will enhance the value of our shares. Shares repurchased under this program are accounted for as treasury shares and the total cost of shares repurchased is recorded as a reduction of shareholders' equity. During the three months ended December 31, 2021, we did not repurchase any shares under the Repurchase Program. As of December 31, 2021, approximately $13.4 million remained available under the Repurchase Program.
