Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
The Company and Significant Accounting Policies | The Company and Significant Accounting Policies The Company Alpha and Omega Semiconductor Limited and its subsidiaries (the “Company”, “AOS”, “we” or “us”) design, develop and supply a broad range of power semiconductors. The Company's portfolio of products targets high-volume applications, including personal and portable computers, graphic cards, flat panel TVs, home appliances, smart phones, battery packs, quick chargers, home appliances, consumer and industrial motor controls and power supplies for TVs, computers, servers and telecommunications equipment. The Company conducts its operations primarily in the United States of America (“USA”), Hong Kong, China, and South Korea. Basis of Preparation The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and a subsidiary in which it had a controlling interest until December 1, 2021. As of December 2, 2021, the Company ceased having control over this subsidiary. Therefore, the Company deconsolidated this subsidiary as of that date. Subsequently, the Company has accounted for it using the equity method of accounting. All intercompany account balances and transactions have been eliminated. The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Joint Venture 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 in the Liangjiang New Area of Chongqing, China (the “JV Transaction”). 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. As of December 2, 2021, the Company ceased having control over the JV Company. Therefore, the Company deconsolidated 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. As of June 30, 2023, the percentage of outstanding JV equity interest beneficially owned by the Company was reduced to 42.2%. Such reduction reflects (i) the sale by the Company of approximately 2.1% of the outstanding JV equity interest which resulted in the deconsolidation of the JV Company, (ii) additional sale by the Company of approximately 1.1% of outstanding JV equity interest in December 2021, (iii) the adoption of an employee equity incentive plan and the issuance of additional equity interest equivalent to 3.99% of the JV Company to investors in exchange for cash in December 2021, and (iv) issuance of additional equity interest of JV to investors in January 2022. In February 2024, the JV Company repurchased certain shares that were previously issued to employees under the employee equity incentive plan, which increased the Company’s percentage of equity ownership in the JV Company by 0.54%. As of June 30, 2024, the percentage of outstanding JV equity interest beneficially owned by the Company was 42.8%. Risks and Uncertainties The Company is subject to certain risks and uncertainties. The Company believes changes in any of the following areas could have a material adverse effect on the Company's future financial position or results of operations or cash flows: the macroeconomic condition and cyclical nature of the semiconductor industry; the timing and success of new product development, including market receptiveness, operation of in-house manufacturing facilities, litigation or claims against the Company based on intellectual property, patent, product regulatory or other factors, competition from other products, general economic conditions, the inability to attract and retain qualified employees, lack of control of the JV Company and ultimately to sustain profitable operations, risks associated with doing business in China, and ability to diversify products and develop digital business; the general state of the U.S., China and world economies; the loss of any of its larger customers; restrictions on the Company’s ability to sell to foreign customers due to trade laws, regulations and requirements; disruptions of the supply chain of components needed for our products; inability to obtain additional financing; inability to meet certain debt covenants; fundamental changes in the technology underlying the Company’s products; successful and timely completion of product design efforts; and new product design introductions by competitors. Additional risks and uncertainties that the Company is unaware of, or that the Company currently believes are not material, may also become important factors that adversely affect its business. The Company's revenue is limited by its ability to utilize wafer production and packaging and testing capacity from its in-house facilities and obtain adequate wafer supplies from third-party foundries. Currently the Company's main third-party foundry is Shanghai Hua Hong Grace Electronic Company Limited, or HHGrace, located in Shanghai, China. HHGrace has been manufacturing wafers for the Company since 2002. HHGrace manufactured approximately 3.8%, 9.6% and 10.3% of the wafers used in the Company's products for the fiscal years ended June 30, 2024, 2023 and 2022, respectively. Although the Company believes that its volume of production allows the Company to secure favorable pricing and priority in allocation of capacity in its third-party foundries, if the foundries' capacities are constrained due to market demands, HHGrace, together with other foundries from which the Company purchases wafers, may not be willing or able to satisfy all of the Company's manufacturing requirements on a timely basis and/or at favorable prices. In addition, manufacturing facilities' capacity affects the Company's gross margin because the Company has certain fixed costs associated with its Oregon Fab as well as in-house packaging and testing facilities. If the Company fails to utilize its manufacturing facilities' capacity at a desirable level, its financial condition and results of operations will be adversely affected. Use of Estimates The preparation of the 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 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. Foreign Currency Transactions and Translation Most of the Company's principal subsidiaries use U.S. dollars as their functional currency because their transactions are primarily conducted and settled in U.S. dollars. All of their revenues and a significant portion of their operating expenses are denominated in U.S. dollars. The functional currencies for the Company's in-house packaging and testing facilities in China are U.S. dollars, and a majority of their capital expenditures are denominated in U.S. dollars. Foreign currency transactions are translated into the functional currencies using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses, resulting from the settlement of such transactions and from the re-measurement of monetary assets and liabilities denominated in foreign currencies using exchange rates at balance sheet date and non-monetary assets and liabilities using historical exchange rates, are recognized in the consolidated statements of operations. For the Company's subsidiaries which use the local currency as their functional currency, their results and financial position are translated into U.S. dollars using exchange rates at balance sheet dates for assets and liabilities and using average exchange rates for income and expenses items. The resulting translation differences are presented as a separate component of accumulated other comprehensive income (loss) in the consolidated statements of equity. Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents primarily consist of cash on hand and short-term bank deposits with original maturities of three months or less. Cash equivalents are highly liquid investments with stated maturities of three months or less as of the dates of purchase. The carrying amounts reported for cash and cash equivalents are considered to approximate fair values based upon their short maturities. Cash and cash equivalents are maintained with reputable major financial institutions. If, due to current economic conditions or other factors, one or more of the financial institutions with which the Company maintains deposits fails, the Company's cash and cash equivalents may be at risk. Deposits with these banks may exceed the amount of insurance provided on such deposits; however, these deposits typically may be redeemed upon demand and, therefore, bear minimal risk. The Company maintains restricted cash in connection with cash balances temporarily restricted for regular business operations. These balances have been excluded from the Company’s cash and cash equivalents balance and are classified as restricted cash in the Company’s consolidated balance sheets. As of June 30, 2024 and 2023, the amount of restricted cash was $0.4 million and $0.4 million, respectively. Accounts Receivable, net The allowance for expected credit loss is based on assessment of the expected collectability of accounts receivable from customers. The Company reviews the allowance by considering factors such as historical collection experience, credit quality, age of the accounts receivable balances and current economic conditions that may affect a customer's ability to pay. The Company writes off a receivable and charges against its recorded allowance when it has exhausted its collection efforts without success. Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy is based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, which are the following: • Level 1 - Quoted prices in active markets for identical assets or liabilities. • Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Fair Value of Financial Instruments The fair value of cash equivalents is based on observable market prices and have been 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 and terms of the debts. Inventories The Company carries inventories at the lower of cost (determined on a first-in, first-out basis) or net realizable value. Cost includes semiconductor wafer and raw materials, labor, depreciation expenses and other manufacturing expenses and overhead, and packaging and testing fees paid to third parties if subcontractors are used. Valuation of inventories are based on the Company's periodic review of inventory quantities on hand as compared with its sales forecasts, historical usage, aging of inventories, production yield levels and current product selling prices. If actual market conditions are less favorable than those forecasted by management, additional future inventory write-downs may be required that could adversely affect the Company's operating results. Adjustments to inventory once established are not reversed until the related inventory has been sold or scrapped. If actual market conditions are more favorable than expected and the products that have previously been written down are sold, our gross margin would be favorably impacted. Property, Plant and Equipment Property, plant and equipment are stated at historical cost less accumulated depreciation. Historical cost includes expenditures that are directly attributable to the acquisition of the items and the costs incurred to make the assets ready for their intended use. Depreciation is provided for on a straight-line basis over the estimated useful lives of the related assets as follows: Building and building improvements 20 years Manufacturing machinery and equipment 7 to 10 years Equipment and tooling 3 to 5 years Computer hardware and software 3 to 5 years Office furniture and equipment 3 to 5 years Leasehold improvements 2 to 15 years Vehicle 5 years Equipment and construction in progress represent equipment received but the necessary installation has not been fully performed or building construction and leasehold improvements have been started but not yet completed. Equipment and construction in progress are stated at cost and transferred to the respective asset class when fully completed and ready for their intended use. Internal-use software development costs are capitalized to the extent that the costs are directly associated with the development of identifiable and unique software products controlled by the Company that will probably generate economic benefits beyond one year. Costs incurred during the application development stage are required to be capitalized. The application development stage is characterized by software design and configuration activities, coding, testing and installation. Training costs and maintenance are expensed as incurred, while upgrades and enhancements are capitalized if it is probable that such expenditures will result in additional functionality. Costs include employee costs incurred and fees paid to outside consultants for the software development and implementation. Internally developed software is amortized over its estimated useful life of three Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognized as selling, general and administrative expenses in the consolidated statements of operations. Costs of maintenance and repairs that do not improve or extend the lives of the respective assets are expensed as incurred. 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 fiscal year ended June 30, 2024, the Company reduced property, plant and equipment by $1.0 million. During the fiscal year ended June 30, 2023, the Company reduced property, plant and equipment by $0.6 million and operating expenses by $0.1 million. During the fiscal year ended June 30, 2022, the Company reduced interest expense by $0.9 million, property, plant and equipment by $1.4 million, and operating expenses by $0.2 million. Long-lived Assets The Company reviews all long-lived assets whenever events or changes in circumstance indicate that these assets may not be recoverable. When evaluating long-lived assets, if the Company concludes that the estimated undiscounted cash flows attributable to the assets are less than their carrying value, the Company recognizes an impairment loss based on the excess of the carrying amount of the assets over their respective fair values, which could adversely affect its results of operations. There was no impairment of long-lived assets for fiscal years 2024, 2023 and 2022. 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, as determined by the agreed upon shipping terms, 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 60 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, current expectations, 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 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. License and Development Services Revenue Recognition In February 2023, the Company entered into a license agreement with a customer to license the Company’s proprietary SiC technology and to provide 24-months of engineering and development services for a total fee of $45.0 million, consisting of an upfront fee of $18.0 million, $6.8 million and $9.0 million paid to the Company in March 2023, July 2023 and February 2024, respectively, with the remaining amount to be paid upon the achievement of specified engineering services and product milestones. The license and development fee is determined to be one performance obligation and is recognized over the 24 months when the Company performs the engineering and development services. The Company uses the input method to measure progression, representing a faithful depiction of the transfer of services. During the fiscal years ended June 30, 2024 and 2023, the Company recorded $21.2 million and $9.9 million of license and development revenue, respectively. The amount of contract liability is recorded as deferred revenue on the consolidated balance sheets. In addition, the Company also entered an accompanying supply agreement to provide limited wafer supply to the customer. 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 consolidated balance sheets. Finance leases are included in property, plant and equipment, finance lease liabilities and long-term finance leases liabilities on the 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 determines 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 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 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. Product Warranty The Company provides a standard one-year warranty for products from the date of purchase by the end customers. The Company accrues for estimated warranty costs at the time revenue is recognized. The Company's warranty obligation is determined by product failure rates, labor and material costs for replacing defective parts, related freight costs for failed parts and other quality assurance costs. The Company monitors its product returns for warranty claims and maintains warranty reserves based on historical experiences and anticipated warranty claims known at the time of estimation. Shipping and Handling Costs Shipping and handling costs are included in cost of goods sold. Research and Development Research and development costs are expensed as incurred. Provision for Income Taxes Income tax expense or benefit is based on income or loss before taxes. Deferred tax assets and liabilities are recognized principally for the expected tax consequences of temporary differences between the tax basis of assets and liabilities and their reported amounts. The Company is subject to income taxes in a number of jurisdictions. Significant judgment is required in determining the worldwide provision for income taxes. There are many transactions and calculations for which the ultimate tax determination is uncertain during the ordinary course of business. The Company establishes accruals for certain tax contingencies based on estimates of whether additional taxes may be due. While the final tax outcome of these matters may differ from the amounts that were initially recorded, such differences will impact the income tax and deferred tax provisions in the period in which such determination is made. Significant management judgment is also required in determining whether deferred tax assets will be realized in full or in part. When it is more likely than not that all or some portion of specific deferred tax assets such as net operating losses or research and experimentation tax credit carryforwards will not be realized, a valuation allowance must be established for the amount of the deferred tax assets that cannot be realized. The Company considers all available positive and negative evidence on a jurisdiction-by-jurisdiction basis when assessing whether it is more likely than not that deferred tax assets are recoverable. The Company considers evidence such as our past operating results, the existence of cumulative losses in recent years and our forecast of future taxable income. The Company has concluded that it should report a full valuation allowance on its state research and development (R&D) tax credit carryforwards as the Company annually generates more state R&D tax credits than it could use based on its forecasts. The Financial Accounting Standards Board (FASB), issued guidance which clarifies the accounting for income taxes by prescribing a minimum probability threshold that a tax position must meet before a financial statement benefit is recognized. The minimum threshold is defined as a tax position that is more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The tax benefit to be recognized is measured as the largest amount of benefit that is greater than fifty percent likely to be realized upon ultimate settlement. Although the guidance on the accounting for uncertainty in income taxes prescribes the use of a recognition and measurement model, the determination of whether an uncertain tax position has met those thresholds will continue to require significant judgment by management. If the ultimate resolution of tax uncertainties is different from what is currently estimated, a material impact on income tax expense could result. The Company's provision for income taxes is subject to volatility and could be adversely impacted by changes in earnings or tax laws and regulations in various jurisdictions. The Company is subject to the continuous examination of our income tax returns by the Internal Revenue Service and other tax authorities. The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. To the extent that the final tax outcome of these matters is different from the amounts recorded, such differences will impact the provision for income taxes in the period in which such determination is made. The provision for income taxes includes the impact of changes to reserves, as well as the related net interest and penalties. 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 Black-Scholes option valuation model requires the input of subjective assumptions, including the expected term and stock price volatility. In addition, judgment is also required in estimating the number of stock-based awards that are expected to be forfeited. Forfeitures are estimated based on historical experience at the time of grant. Changes in estimated forfeitures are recognized in the period of change and impact the amount of stock compensation expenses to be recognized in future periods, which could be material if actual results differ significantly from estimates. 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. Advertising Advertising expenditures are expensed as incurred. Advertising expense was $0.6 million, $0.5 million and $0.2 million in the fiscal years ended June 30, 2024, 2023, and 2022, respectively. Comprehensive Income (Loss) Comprehensive income (loss) 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 (loss) consists of cumulative foreign currency translation adjustments. Recent Accounting Pronouncements Recently Adopted Accounting Standards None Recently Issued Accounting Standards not yet adopted In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740) – Improvements to Income Tax Disclosures”, which enhances the transparency, effectiveness and comparability of income tax disclosures by requiring consistent categories and greater disaggregation of information related to income tax rate reconciliations and the jurisdictions in which income taxes are paid. This guidance is effective for annual periods beginning after December 15, 2024 with early adoption permitted. The Company is currently evaluating the impact of the ASU on its income tax disclosures within the consolidated financial statements. In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280) – Improvements to Reportable Segment Disclosures”, which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This ASU also expands disclosure requirements to enable users of financial statements to better understand the entity’s measurement and assessment of segment performance and resource allocation. This guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of the ASU on its disclosures within the consolidated financial statements. |

Equity Method Investment in Equity Investee | 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”), 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 the 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, the Company recorded a gain on deconsolidation of $399.1 million during the fiscal year ended June 30, 2022 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 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 in exchange to 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. On January 26, 2022, the JV Company completed a financing transaction pursuant to a corporate investment agreement (the “Investment Agreement”) between the JV Company and certain third-party investors (the “New Investors”). Under the Investment Agreement, the New Investors purchased newly issued equity interest of the JV Company, representing approximately 7.82% of post-transaction outstanding equity interests of the JV Company, for a total purchase price of RMB 509 million (or approximately USD 80 million based on the currency exchange rate as of January 26, 2022) (the “Investment”). Following the closing of the Investment and as of June 30, 2022, the percentage of outstanding JV equity interest beneficially owned by the Company was reduced to 42.2%. The net loss associated with these sales of JV Company equity interest held by the Company was recorded in the fiscal year ended June 30, 2022 as follows: (in thousands) Gain on 1.1% equity interest sold $ 475 Loss on diluted equity interest from issuance of shares under the employee equity incentive plan (8,116) Gain on 7.82% equity interest sold 4,501 Loss on changes on equity interest of the JV Company, net $ (3,140) In February 2024, the JV Company repurchased certain shares that were previously issued to employees under the employee equity incentive plan, which increased the Company’s percentage of equity ownership in the JV Company by 0.54%. As of June 30, 2024, the percentage of outstanding JV equity interest beneficially owned by the Company was 42.8%. 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. During the fiscal years ended June 30, 2024, 2023 and 2022, the Company recorded $4.8 million, $1.4 million and $2.6 million of its equity in loss of the JV Company, respectively, using lag reporting.

Net Income (Loss) Per Common Share Attributable to Alpha and Omega Semiconductor Limited | Net Income (Loss) Per Common Share Attributable to Alpha and Omega Semiconductor Limited Basic net income (loss) per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted-average number of common shares outstanding, plus potential shares of common stock during the period. Potential shares of common stock include dilutive shares attributable to the assumed exercise of share options, ESPP shares and vesting of RSUs using the treasury stock method and contingent issuances of common shares related to convertible preferred shares, if dilutive. Under the treasury stock method, potential common shares outstanding are not included in the computation of diluted net income (loss) per share if their effect is anti-dilutive.

Risks and Uncertainties [Abstract] | |
Concentration of Credit Risk and Significant Customers | 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 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 standards, 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. Summarized below are individual customers whose revenue or accounts receivable balances were 10% or higher than the respective total consolidated amounts: Year Ended June 30, Percentage of revenue 2024 2023 2022 Customer A 25.0 % 21.6 % 24.6 % Customer B 46.0 % 35.6 % 39.7 % Customer D * 14.0 % * June 30, Percentage of accounts receivable 2024 2023 Customer A * 15.3 % Customer B * 17.6 % Customer C 33.4 % 13.3 % Customer D 33.4 % 30.9 % * Less than 10% |

Leases [Abstract] | |
Leases | 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 consolidated balance sheets. Finance leases are included in property, plant and equipment, finance lease liabilities and finance lease liabilities-long-term on the 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 $5.1 million of a machinery lease financing with a vendor. In September 2022, the lease was amended to make a monthly payment of principal and interest as a fixed amount effective in October 2022. Other terms remain the same. The amendment was accounted for as a debt modification and no gain or loss was recognized. The Company does not record leases on the consolidated balance sheet with a term of one year or less.

Stockholders' Equity Note [Abstract] | |
Shareholders' Equity | Shareholders' Equity Common Shares The Company's Bye-laws, as amended, authorized the Company to issue 100,000,000 common shares with par value of $0.002. Each common share is entitled to one vote. The holders of common shares are also entitled to receive dividends whenever funds are legally available and when and if declared by the board of directors. No dividends had been declared as of June 30, 2024. 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 stock-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. As of June 30, 2023, there were no availability under this repurchase program, which was terminated. During fiscal year 2023, the Company repurchased an aggregate of 548,132 shares, from the open market for a total cost of approximately $13.4 million, excluding fees and related expenses, at an average price of $24.51 per share. During fiscal year 2024 and 2022, the Company did not repurchase any shares pursuant to the repurchase program. As of June 30, 2024, the Company had repurchased an aggregate of 7,332,780 shares for a total cost of $81.1 million, at an average price of $11.01 per share, excluding fees and related expenses, since inception of the program. No repurchased shares have been retired. Of the 7,332,780 repurchased shares, 194,716 shares with a weighted average repurchase price of $9.77 per share, were reissued at an average price of $4.29 per share for option exercises and vested restricted stock units (“RSU”). |

Share-based Compensation | Share-based Compensation 2018 Omnibus Incentive Plan The 2009 Share Option/Share Issuance Plan (the “2009 Plan”) was approved in September 2009 at the annual general meeting of shareholders in connection with the Company's IPO. At the annual general meeting of shareholders in November 2018, the 2009 Plan was approved to be terminated and the 2018 Omnibus Incentive Plan (the “2018 Plan”) was effective. No further awards will be made under the 2009 Plan. The 2018 Plan authorized the board of directors to grant incentive share options, non-statutory share options and restricted shares to employees, directors, non-employee directors and consultants of the Company and its subsidiaries for up to 2,065,000 common shares. The 2018 Plan does not include an evergreen authorization Therefore, the Company is not permitted to increase the number of shares reserved in the share pool without obtaining further shareholder approval. Outstanding shares under the 2018 Plan and awards granted under the 2009 Plan that expire, are forfeited or cancelled or terminate prior to the issuance of the shares subject to those awards or are settled in cash will be available for subsequent issuance under the 2018 Plan. At the annual general meeting of shareholders in November 2021, 2022 and 2023, the 2018 Plan was approved to increase by 1,000,000, 740,000 and 427,000 shares, respectively, to a total of 4,232,000 shares. As of June 30, 2024, 919,093 shares were available for grant under the 2018 Plan. Beginning with the 2014 Annual Shareholders Meeting, on the date of each annual shareholders meeting, each individual who commences service as a non-employee Board member by reason of his or her election to the Board at such annual meeting and each individual who is to continue to serve as a non-employee Board member, whether or not that individual is standing for re-election to the Board at that particular annual meeting, will automatically be granted an award in the form of restricted share units covering that number of common shares determined by dividing one hundred sixty thousand dollars ($160,000) by the average fair market value per share for the ninety (90)-day period preceding the grant date, up to a maximum of 10,000 shares. Under the 2018 Plan, incentive share options and RSU are to be granted at a price that is not less than 100% and nonstatutory share options are to be granted at not less than 85% of the fair value of the common shares, at the date of grant for employees and consultants. Options and RSUs generally vest over a four-year to five-year period, and are exercisable for a maximum period of ten years after the date of grant. The fair value of RSU, including time-based restricted stock units and performance-based restricted stock units is based on the market price of the Company's common shares on the date of grant. Time-based Restricted Stock Units (“TRSU”) The following table summarizes the Company's TRSU activities: Number of Time-based Restricted Stock Units Weighted Average Weighted Average Aggregate Intrinsic Value Nonvested at June 30, 2021 1,053,524 $ 21.60 1.73 $ 32,016,594 Granted 597,381 $ 45.83 Vested (410,670) $ 20.54 Forfeited (70,626) $ 26.79 Nonvested at June 30, 2022 1,169,609 $ 34.03 1.73 $ 38,994,764 Granted 714,080 $ 27.70 Vested (451,549) $ 28.84 Forfeited (47,075) $ 33.40 Nonvested at June 30, 2023 1,385,065 $ 32.48 1.73 $ 45,430,132 Granted 679,993 $ 23.12 Vested (521,109) $ 30.00 Forfeited (74,814) $ 30.34 Nonvested at June 30, 2024 1,469,135 $ 29.13 1.66 $ 54,901,575 Performance-based Restricted Stock Units (“PRSU”) In March each year since fiscal year 2017, the Company granted PRSU to certain personnel.

The following table summarizes the Company’s PRSU activities: Number of Performance-based Restricted Stock Weighted Average Weighted Average Aggregate Intrinsic Value Nonvested at June 30, 2021 353,824 $ 22.69 1.74 $ 10,752,711 Granted 194,000 $ 48.65 Vested (151,199) $ 19.44 Forfeited (7,250) $ 40.33 Nonvested at June 30, 2022 389,375 $ 36.56 1.85 $ 12,981,763 Granted 264,214 $ 25.70 Vested (116,132) $ 30.54 Forfeited (10,743) $ 48.65 Nonvested at June 30, 2023 526,714 $ 32.19 1.78 $ 17,276,219 Granted 209,250 $ 21.55 Vested (123,632) $ 30.50 Forfeited (268,207) $ 26.59 Nonvested at June 30, 2024 344,125 $ 30.69 1.73 $ 12,859,951 Market-based Restricted Stock Units (“MSUs”) I n December 2021, the Company granted 1.0 million market-based restricted stock units to certain non-officer personnel. The number of shares to be earned at the end of the performance period was 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 MSUs using a Monte-Carlo simulation model. In September 2023, the Company determined it was no longer probable that it would achieve the minimum revenue threshold specified in the awards. Therefore, the Company reversed all of the previously recognized expenses of $6.4 million for these MSUs. In addition, on September 19, 2023, the Compensation Committee of the Board approved a modification of the terms of MSUs to extend the performance period through December 31, 2025, changed the commencement date for the four-year time-based service period to January 1, 2026, and reduced the achievement of specified stock prices and revenue thresholds. The fair value of these MSUs was revalued to reflect the change using a Monte-Carlo simulation model with the following assumptions: risk-free interest rate of 4.94%, expected term of 2.28 years, expected volatility of 61.38% and dividend yield of 0%. In June 2024, the Company determined it was no longer probable that the revenue thresholds for the modified MSU would be achieved. Therefore, the Company reversed $2.4 million in the June 2024 quarter that was recorded during the fiscal year 2024 related to the modification on September 19, 2023. The Company recorded approximately $(6.4) million, $1.9 million and $4.5 million of expenses for these MSUs during the fiscal years ended June 30, 2024, 2023 and 2022, respectively. 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 the 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 performance period. 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 modified MSUs were valued immediately before and after the modification, using Monte-Carlo simulation pricing model. The Monte-Carlo simulation pricing model applied the following assumptions for pre-modification conditions: risk-free interest rate of 0.13%, expected term of 1.3 years, expected volatility of 66.7% and dividend yield of 0%; and for post-modification conditions: risk-free interest rate of 0.14%, expected term of 2.3 years, expected volatility of 59.1% and dividend yield of 0%. 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 $1.0 million, $3.9 million and $1.6 million of expense for these MSUs during the years ended June 30, 2024, 2023 and 2022, respectively. The following table summarizes the Company’s MSUs activities: Number of Market-based Restricted Stock Units Weighted Average Weighted Average Aggregate Intrinsic Value Nonvested at June 30, 2021 1,240,000 $ 5.17 3.84 $ 37,683,600 Granted 1,022,000 $ 48.44 Forfeited (56,000) $ 9.81 Nonvested at June 30, 2022 2,206,000 $ 25.10 3.83 $ 73,548,040 Vested (90,000) $ 5.17 Forfeited (8,000) $ 48.44 Nonvested at June 30, 2023 2,108,000 $ 25.86 2.96 $ 69,142,400 Vested (275,000) $ 5.17 Forfeited (106,000) $ 42.32 Nonvested at June 30, 2024 1,727,000 $ 28.15 2.83 $ 64,537,990 Stock Option The following table summarizes the Company's stock option activities: Weighted Weighted Average Average Remaining Number of Exercise Price Contractual Aggregate Shares Per Share Term (in years) Intrinsic Value Outstanding at June 30, 2021 487,875 $ 7.99 2.32 Exercised (98,000) $ 9.15 $ 3,936,675 Outstanding at June 30, 2022 389,875 $ 7.70 1.53 Exercised (65,500) $ 8.42 $ 1,442,646 Canceled or forfeited (5,000) $ 9.19 Outstanding at June 30, 2023 319,375 $ 7.53 0.72 $ 8,071,631 Exercised (309,375) $ 7.48 $ 5,588,750 Outstanding at June 30, 2024 10,000 $ 9.07 0.13 $ 283,000 Options vested and expected to vest 10,000 $ 9.07 0.13 $ 283,000 Exercisable at June 30, 2024 10,000 $ 9.07 0.13 $ 283,000 The aggregate intrinsic value for options outstanding at June 30, 2024 in the table above is based on the Company’s common stock closing price on June 30, 2024. The 2018 Employee Share Purchase Plan At the annual general meeting of shareholders in November 2018, the 2018 Employee Share Purchase Plan (“Purchase Plan” or “ESPP”) Plan was approved, under which 1,430,000 common shares are available for issuance. The Purchase Plan does not include an evergreen authorization, therefore the Company is not permitted to increase the number of shares reserved in the share pool without obtaining further shareholder approval. At the general meeting of shareholders in November 2021, and 2023, the ESPP Plan was approved to increase by 1,070,000 and 1,200,000 shares, respectively to a total of 3,700,000 shares. The Purchase Plan provided for a series of overlapping offering periods with a duration of 24 months, generally beginning on May 15 and November 15 of each year. The Purchase Plan allows employees to purchase common shares through payroll deductions of up to 15% of their eligible compensation. Such deductions will accumulate over a six-month accumulation period without interest. After such accumulation period, common shares will be purchased at a price equal to 85% of the fair market value per share on either the first day of the offering period or the last date of the accumulation period, whichever is less. The maximum number of shares that may be purchased by a participant on any purchase date may not exceed 875 shares for a total of 3,500 shares per a 24-month offering period. In addition, no participant may purchase more than $25,000 worth of common stock in any one calendar year period. No more than 300,000 common shares may be purchased by all participants on any purchase date. The ESPP is compensatory and results in compensation expense. The fair values of common shares to be issued under the ESPP were determined using the Black-Scholes option pricing model with the following assumptions: Year Ended June 30, 2024 2023 2022 Volatility rate 53.0% - 64.3% 64.0% - 70.5% 66.4% - 69.9% Risk-free interest rate 5.0% - 5.2% 4.5% - 4.6% 0.3% - 2.1% Expected term 1.3 years 1.3 years 1.3 years Dividend yield —% —% —% The weighted-average estimated fair value of employee stock purchase rights granted pursuant to the ESPP during the years ended June 30, 2024, 2023 and 2022 was $10.16, $11.46 and $16.48 per share, respectively. Share-based Compensation Expenses The total share-based compensation expense related to TRSU, PRSUs, MSUs, stock options and ESPP described above, recognized in the consolidated statements of operations for the years presented was as follows: Year Ended June 30, 2024 2023 2022 (in thousands) Cost of goods sold $ 3,434 $ 5,851 $ 5,125 Research and development 5,210 9,437 7,049 Selling, general and administrative 12,997 22,200 19,150 $ 21,641 $ 37,488 $ 31,324 |

The change in valuation allowance for June 30, 2024 and 2023 was an increase of $0.6 million and an increase of $0.9 million, respectively. At June 30, 2024 and 2023, the Company provided a valuation allowance for its state research and development credit carryforward deferred tax assets of $7.3 million and $6.7 million, respectively, as it generated more state tax credits each year than it can utilize. The Company intends to maintain a valuation allowance equal to the state research and development credit carryforwards in excess of the state net deferred tax liabilities on all other state book/tax differences and net operating loss carryforward. At June 30, 2024, the Company had federal research and development tax credit carryforwards of approximately $8.2 million. The federal tax credits begin to expire in 2040, if not utilized. At June 30, 2024, the Company had state tax credit carryforwards of approximately $9.9 million, of which $9.0 million carryforward indefinitely, $0.6 million have a 10 to 15 year life (beginning to expire in 2033) and $0.3 million with a 20 year life, (beginning to expire in 2038). The Company intends to reinvest the undistributed earnings of its foreign subsidiaries indefinitely, except for Alpha and Omega Semiconductor (Cayman) Ltd. and AOS International LP. As of June 30, 2024, the cumulative earnings of Alpha and Omega Semiconductor (Cayman) and AOS International LP totaled $46.2 million, and there was no deferred tax liability recorded as there is no income nor withholding tax amongst the applicable jurisdictions. As of June 30, 2024, the cumulative amount of undistributed earnings of its foreign entities considered permanently reinvested is $414.6 million. Should the Company decide to remit this income to its Bermuda parent company in a future period, its provision for income taxes may increase materially in that period. The determination of the unrecognized deferred tax liability on these earnings is not practicable due to the complexity and variety of assumptions necessary to estimate the tax. As of June 30, 2024, the Company has recorded a deferred tax liability of $26.3 million for the basis difference related to our investment in the JV Company. A reconciliation of the beginning and ending amount of unrecognized tax benefits from July 1, 2021 to June 30, 2024 is as follows: Year Ended June 30, 2024 2023 2022 (in thousands) Balance at beginning of year $ 9,335 $ 8,609 $ 7,645 Additions based on tax positions related to the current year 764 804 1,121 Reductions based on tax positions related to prior years (11) (68) (40) Reductions due to lapse of applicable statute of limitations — (10) (117) Balance at end of year $ 10,088 $ 9,335 $ 8,609 At June 30, 2024, the total unrecognized tax benefits of $10.1 million included $7.1 million of unrecognized tax benefits that have been netted against the related deferred tax assets. The remaining $3.0 million of unrecognized tax benefits was recorded within long-term income tax payable on the Company's consolidated balance sheet as of June 30, 2024. The Company cannot reasonably estimate the timing and amount of potential cash settlements on the unrecognized tax benefits. The total unrecognized tax benefits of $10.1 million at June 30, 2024 included $6.9 million that, if recognized, would reduce the effective income tax rate in future periods. It is reasonably possible that the Company will recognize approximately $0.2 million reduction to its uncertain tax positions during the next twelve months due to a lapse in the applicable statute of limitations.. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. To the extent accrued interest and penalties do not ultimately become payable, amounts accrued will be reduced and reflected as a reduction of the overall income tax provision in the period that such determination is made. The amount of interest and penalties accrued at June 30, 2024 was $0.5 million, of which $0.2 million was recognized in the year ended June 30, 2024. The amount of interest and penalties accrued at June 30, 2023 was $0.3 million, of which $0.1 million was recognized in the year ended June 30, 2023. |

Segment Reporting [Abstract] | |
Segment and Geographic Information | 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-makers are the Executive Chairman and the Chief Executive Officer. The financial information presented to the Company’s Executive Chairman and 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. In February 2023, the Company entered into a license agreement with a customer to license the Company’s proprietary SiC technology and to provide 24-months of engineering and development services for a total fee of $45.0 million. The revenue by geographical location in the following tables is based on the country or region in which the products were shipped to: Year Ended June 30, 2024 2023 2022 (in thousands) Hong Kong $ 524,788 $ 561,855 $ 630,238 China 95,417 84,546 120,978 South Korea 9,956 9,168 11,802 United States 4,938 19,744 12,470 Other countries 22,175 16,008 2,064 $ 657,274 $ 691,321 $ 777,552 Year Ended June 30, 2024 2023 2022 (in thousands) Power discrete $ 426,146 $ 458,795 $ 545,135 Power IC 205,778 218,620 220,882 Packaging and testing services and other 4,119 3,979 11,535 License and development services 21,231 9,927 — $ 657,274 $ 691,321 $ 777,552 Long-lived assets, net consisting of property, plant and equipment and land use rights, net, as well as operating lease right-of-use assets, net by geographical area are as follows: June 30, 2024 2023 (in thousands) China $ 106,666 $ 114,822 United States 249,791 263,083 Other countries 5,212 4,275 $ 361,669 $ 382,180 |

Restrictions for Consolidated and Unconsolidated Subsidiaries [Abstract] | |
Restricted Net Assets | Restricted Net Assets Laws and regulations in China permit payments of dividends by the Company's subsidiaries in China only out of their retained earnings, if any, as determined in accordance with China accounting standards and regulations. Each China subsidiary is also required to set aside at least 10% of its after-tax profit, if any, based on China accounting standards each year to its statutory reserves until the cumulative amount of such reserves reaches 50% of its registered capital. As a result of these China laws and regulations, the Company's subsidiaries in China are restricted in their abilities to transfer a portion of their net assets to the Company. As of June 30, 2024 and 2023, such restricted portion amounted to approximately $93.5 million and $93.2 million, or 10.5% and 10.5%, of our total consolidated net assets attributable to the Company, respectively. As the Company's subsidiaries in China are not revenue generating operating units, the Company does not expect to repatriate funds in the form of dividends, loans or advances from its subsidiaries in China for working capital and other funding purposes. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies Purchase commitments As of June 30, 2024 and 2023, the Company had approximately $100.8 million and $127.5 million, respectively, of outstanding purchase commitments primarily for purchases of semiconductor raw materials, wafers, spare parts, packaging and testing services and others. As of June 30, 2024 and 2023, the Company had approximately $6.9 million, and $9.7 million, respectively, of commitments for the purchase of property and equipment. Other commitments See Notes 1, 7 and 8 to the Consolidated Financial Statements contained in this annual Report on Form 10-K for descriptions of commitments including Joint Venture, 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. As previously disclosed, the Company is currently cooperating with Department of Commerce (“DOC”) in connection with its investigation of the Company’s export control practices. DOC has not informed the Company of any specific timeline or schedule under which DOC will complete its review. Given the case is in still ongoing and DOC have not 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. 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 June 30, 2024 and 2023. 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 maintain such insurance coverage at reasonable cost, if at all, in the future. Environmental matters The Company is subject to various federal, state, local, and foreign laws and regulations governing environmental matters, including the use, handling, discharge, and disposal of hazardous materials. The Company believes that it has been in material compliance with applicable environmental regulations and standards. Complying with current laws and regulations has not had a material adverse effect on the Company’s financial condition and results of operations. However, it is possible that additional environmental issues may arise in the future, which the Company cannot currently predict. |

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Basis of Preparation | Basis of Preparation The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and a subsidiary in which it had a controlling interest until December 1, 2021. As of December 2, 2021, the Company ceased having control over this subsidiary. Therefore, the Company deconsolidated this subsidiary as of that date. Subsequently, the Company has accounted for it using the equity method of accounting. |
Risks and Uncertainties | Risks and Uncertainties The Company is subject to certain risks and uncertainties. The Company believes changes in any of the following areas could have a material adverse effect on the Company's future financial position or results of operations or cash flows: the macroeconomic condition and cyclical nature of the semiconductor industry; the timing and success of new product development, including market receptiveness, operation of in-house manufacturing facilities, litigation or claims against the Company based on intellectual property, patent, product regulatory or other factors, competition from other products, general economic conditions, the inability to attract and retain qualified employees, lack of control of the JV Company and ultimately to sustain profitable operations, risks associated with doing business in China, and ability to diversify products and develop digital business; the general state of the U.S., China and world economies; the loss of any of its larger customers; restrictions on the Company’s ability to sell to foreign customers due to trade laws, regulations and requirements; disruptions of the supply chain of components needed for our products; inability to obtain additional financing; inability to meet certain debt covenants; fundamental changes in the technology underlying the Company’s products; successful and timely completion of product design efforts; and new product design introductions by competitors. Additional risks and uncertainties that the Company is unaware of, or that the Company currently believes are not material, may also become important factors that adversely affect its business. The Company's revenue is limited by its ability to utilize wafer production and packaging and testing capacity from its in-house facilities and obtain adequate wafer supplies from third-party foundries. Currently the Company's main third-party foundry is Shanghai Hua Hong Grace Electronic Company Limited, or HHGrace, located in Shanghai, China. HHGrace has been manufacturing wafers for the Company since 2002. HHGrace manufactured approximately 3.8%, 9.6% and 10.3% of the wafers used in the Company's products for the fiscal years ended June 30, 2024, 2023 and 2022, respectively. Although the Company believes that its volume of production allows the Company to secure favorable pricing and priority in allocation of capacity in its third-party foundries, if the foundries' capacities are constrained due to market demands, HHGrace, together with other foundries from which the Company purchases wafers, may not be willing or able to satisfy all of the Company's manufacturing requirements on a timely basis and/or at favorable prices. In addition, manufacturing facilities' capacity affects the Company's gross margin because the Company has certain fixed costs associated with its Oregon Fab as well as in-house packaging and testing facilities. If the Company fails to utilize its manufacturing facilities' capacity at a desirable level, its financial condition and results of operations will be adversely affected. |
Use of Estimates | Use of Estimates The preparation of the 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 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. |
Foreign Currency Transactions and Translation | Foreign Currency Transactions and Translation Most of the Company's principal subsidiaries use U.S. dollars as their functional currency because their transactions are primarily conducted and settled in U.S. dollars. All of their revenues and a significant portion of their operating expenses are denominated in U.S. dollars. The functional currencies for the Company's in-house packaging and testing facilities in China are U.S. dollars, and a majority of their capital expenditures are denominated in U.S. dollars. Foreign currency transactions are translated into the functional currencies using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses, resulting from the settlement of such transactions and from the re-measurement of monetary assets and liabilities denominated in foreign currencies using exchange rates at balance sheet date and non-monetary assets and liabilities using historical exchange rates, are recognized in the consolidated statements of operations. For the Company's subsidiaries which use the local currency as their functional currency, their results and financial position are translated into U.S. dollars using exchange rates at balance sheet dates for assets and liabilities and using average exchange rates for income and expenses items. The resulting translation differences are presented as a separate component of accumulated other comprehensive income (loss) in the consolidated statements of equity. |
Cash and Cash Equivalents, Restricted Cash | Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents primarily consist of cash on hand and short-term bank deposits with original maturities of three months or less. Cash equivalents are highly liquid investments with stated maturities of three months or less as of the dates of purchase. The carrying amounts reported for cash and cash equivalents are considered to approximate fair values based upon their short maturities. Cash and cash equivalents are maintained with reputable major financial institutions. If, due to current economic conditions or other factors, one or more of the financial institutions with which the Company maintains deposits fails, the Company's cash and cash equivalents may be at risk. Deposits with these banks may exceed the amount of insurance provided on such deposits; however, these deposits typically may be redeemed upon demand and, therefore, bear minimal risk. |
Accounts Receivable | Accounts Receivable, net The allowance for expected credit loss is based on assessment of the expected collectability of accounts receivable from customers. The Company reviews the allowance by considering factors such as historical collection experience, credit quality, age of the accounts receivable balances and current economic conditions that may affect a customer's ability to pay. The |
Fair Value Measurements | Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy is based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, which are the following: • Level 1 - Quoted prices in active markets for identical assets or liabilities. • Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. |
Fair Value of Financial Instruments | Fair Value of Financial Instruments The fair value of cash equivalents is based on observable market prices and have been 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 and terms of the debts. |
Inventories | Inventories |
Property, Plant and Equipment | Property, Plant and Equipment Property, plant and equipment are stated at historical cost less accumulated depreciation. Historical cost includes expenditures that are directly attributable to the acquisition of the items and the costs incurred to make the assets ready for their intended use. Depreciation is provided for on a straight-line basis over the estimated useful lives of the related assets as follows: Building and building improvements 20 years Manufacturing machinery and equipment 7 to 10 years Equipment and tooling 3 to 5 years Computer hardware and software 3 to 5 years Office furniture and equipment 3 to 5 years Leasehold improvements 2 to 15 years Vehicle 5 years Equipment and construction in progress represent equipment received but the necessary installation has not been fully performed or building construction and leasehold improvements have been started but not yet completed. Equipment and construction in progress are stated at cost and transferred to the respective asset class when fully completed and ready for their intended use. Internal-use software development costs are capitalized to the extent that the costs are directly associated with the development of identifiable and unique software products controlled by the Company that will probably generate economic benefits beyond one year. Costs incurred during the application development stage are required to be capitalized. The application development stage is characterized by software design and configuration activities, coding, testing and installation. Training costs and maintenance are expensed as incurred, while upgrades and enhancements are capitalized if it is probable that such expenditures will result in additional functionality. Costs include employee costs incurred and fees paid to outside consultants for the software development and implementation. Internally developed software is amortized over its estimated useful life of three Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognized as selling, general and administrative expenses in the consolidated statements of operations. Costs of maintenance and repairs that do not improve or extend the lives of the respective assets are expensed as incurred. |
Government Grants | Government Grants |
Impairment of Long-Lived Assets | Long-lived Assets The Company reviews all long-lived assets whenever events or changes in circumstance indicate that these assets may not be recoverable. When evaluating long-lived assets, if the Company concludes that the estimated undiscounted cash flows attributable to the assets are less than their carrying value, the Company recognizes an impairment loss based on the excess of the carrying amount of the assets over their respective fair values, which could adversely affect its results of operations. |
Revenue Recognition | 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, as determined by the agreed upon shipping terms, 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 60 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, current expectations, 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 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. License and Development Services Revenue Recognition |
Leases | 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 consolidated balance sheets. Finance leases are included in property, plant and equipment, finance lease liabilities and long-term finance leases liabilities on the consolidated balance sheets. |
Product Warranty | Product Warranty The Company provides a standard one-year warranty for products from the date of purchase by the end customers. The Company accrues for estimated warranty costs at the time revenue is recognized. The Company's warranty obligation is determined by product failure rates, labor and material costs for replacing defective parts, related freight costs for failed parts and other quality assurance costs. The Company monitors its product returns for warranty claims and maintains warranty reserves based on historical experiences and anticipated warranty claims known at the time of estimation. |
Shipping and Handling Costs | Shipping and Handling Costs Shipping and handling costs are included in cost of goods sold. |
Research and Development | Research and Development |
Provision for Income Taxes | Provision for Income Taxes Income tax expense or benefit is based on income or loss before taxes. Deferred tax assets and liabilities are recognized principally for the expected tax consequences of temporary differences between the tax basis of assets and liabilities and their reported amounts. The Company is subject to income taxes in a number of jurisdictions. Significant judgment is required in determining the worldwide provision for income taxes. There are many transactions and calculations for which the ultimate tax determination is uncertain during the ordinary course of business. The Company establishes accruals for certain tax contingencies based on estimates of whether additional taxes may be due. While the final tax outcome of these matters may differ from the amounts that were initially recorded, such differences will impact the income tax and deferred tax provisions in the period in which such determination is made. Significant management judgment is also required in determining whether deferred tax assets will be realized in full or in part. When it is more likely than not that all or some portion of specific deferred tax assets such as net operating losses or research and experimentation tax credit carryforwards will not be realized, a valuation allowance must be established for the amount of the deferred tax assets that cannot be realized. The Company considers all available positive and negative evidence on a jurisdiction-by-jurisdiction basis when assessing whether it is more likely than not that deferred tax assets are recoverable. The Company considers evidence such as our past operating results, the existence of cumulative losses in recent years and our forecast of future taxable income. The Company has concluded that it should report a full valuation allowance on its state research and development (R&D) tax credit carryforwards as the Company annually generates more state R&D tax credits than it could use based on its forecasts. The Financial Accounting Standards Board (FASB), issued guidance which clarifies the accounting for income taxes by prescribing a minimum probability threshold that a tax position must meet before a financial statement benefit is recognized. The minimum threshold is defined as a tax position that is more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The tax benefit to be recognized is measured as the largest amount of benefit that is greater than fifty percent likely to be realized upon ultimate settlement. Although the guidance on the accounting for uncertainty in income taxes prescribes the use of a recognition and measurement model, the determination of whether an uncertain tax position has met those thresholds will continue to require significant judgment by management. If the ultimate resolution of tax uncertainties is different from what is currently estimated, a material impact on income tax expense could result. The Company's provision for income taxes is subject to volatility and could be adversely impacted by changes in earnings or tax laws and regulations in various jurisdictions. The Company is subject to the continuous examination of our income tax returns by the Internal Revenue Service and other tax authorities. The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. To the extent that the final tax outcome of these matters is different from the amounts recorded, such differences will impact the provision for income taxes in the period in which such determination is made. The provision for income taxes includes the impact of changes to reserves, as well as the related net interest and penalties. |
Share-based Compensation Expense | 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 Black-Scholes option valuation model requires the input of subjective assumptions, including the expected term and stock price volatility. In addition, judgment is also required in estimating the number of stock-based awards that are expected to be forfeited. Forfeitures are estimated based on historical experience at the time of grant. Changes in estimated forfeitures are recognized in the period of change and impact the amount of stock compensation expenses to be recognized in future periods, which could be material if actual results differ significantly from estimates. |
Advertising | Advertising Advertising expenditures are expensed as incurred. Advertising expense was $0.6 million, $0.5 million and $0.2 million in the fiscal years ended June 30, 2024, 2023, and 2022, respectively. |

Recent Accounting Pronouncements | Recent Accounting Pronouncements Recently Adopted Accounting Standards None Recently Issued Accounting Standards not yet adopted In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740) – Improvements to Income Tax Disclosures”, which enhances the transparency, effectiveness and comparability of income tax disclosures by requiring consistent categories and greater disaggregation of information related to income tax rate reconciliations and the jurisdictions in which income taxes are paid. This guidance is effective for annual periods beginning after December 15, 2024 with early adoption permitted. The Company is currently evaluating the impact of the ASU on its income tax disclosures within the consolidated financial statements. In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280) – Improvements to Reportable Segment Disclosures”, which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This ASU also expands disclosure requirements to enable users of financial statements to better understand the entity’s measurement and assessment of segment performance and resource allocation. This guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of the ASU on its disclosures within the consolidated financial statements. |
