Notes to Condensed Consolidated Financial Statements (Unaudited)

  1. 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 computers, graphic cards, game consoles, home appliances, power tools, smart phones, battery packs, consumer and industrial motor controls and power supplies for computers, servers and telecommunications equipment. The Company conducts its operations primarily in the United States, Hong Kong, China, and South Korea.

Basis of Preparation

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions to Article 10 of Securities and Exchange Commission Regulation S-X, as amended. They do not include all information and footnotes necessary for a fair presentation of financial position, results of operations and cash flows in conformity with U.S. GAAP for complete financial statements. These Condensed Consolidated Financial Statements should be read in conjunction with the consolidated financial statements and related notes contained in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2025. For a complete discussion of the Company's accounting policies, refer to Part II, Item 8, Note 1 —Significant Accounting Policies in our 2025 Form 10-K. All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) considered necessary for a fair presentation of the results of operations for the periods presented have been included in the interim periods. Operating results for the six months ended December 31, 2025 are not necessarily indicative of the results that may be expected for the fiscal year ending June 30, 2026 or any other interim period. The consolidated balance sheet at June 30, 2025 is derived from the audited financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2025.

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 reserve of stock rotation returns, allowance for price adjustments, allowance for expected credit loss, inventory reserves, warranty accrual, income taxes, leases, share-based compensation, and recoverability of and useful lives for property, plant and equipment.

Recent Accounting Pronouncements

Recently Issued Accounting Standards not yet adopted

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (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 will impact only the Company's disclosures for the annual reporting period ending June 30, 2026, with no impacts to its financial condition or results of operations.

In November 2024, the FASB issued ASU No. 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures”, which improves disclosure requirements and provides more detailed information about an entity’s expenses, specifically amounts related to purchases of inventory, employee compensation, depreciation, intangible asset amortization, and selling expenses, along with qualitative descriptions of certain other types of expenses. This guidance is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of the ASU on its consolidated financial statements.

In July 2025, the FASB issued ASU No. 2025-05, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets”, which provides an optional practical expedient for estimating future credit losses based on current conditions as of the balance sheet date and assuming those conditions do not change over the remaining life of the accounts receivable. The guidance will be effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods, with early adoption permitted. The Company does not expect this ASU to have a material impact on its consolidated financial statements.

In September 2025, the FASB issued ASU No. 2025-06, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software”. The ASU removes references to prescriptive software development stages and includes an updated framework for capitalizing internal software costs. The guidance will be effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the impact of the ASU on its consolidated financial statements.

In December 2025, the FASB issued ASU No. 2025-10, “Accounting for Government Grants Received by Business Entities”. This amendment provides guidance on the recognition, measurement, and presentation of government grants. This amendment will be effective for annual reporting periods beginning after December 15, 2028, and interim reporting periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the impact of the ASU on its consolidated financial statements.

  1. Equity Method Investment in Equity Investee

The Company has accounted for its investment in the JV Company using the equity method of accounting. For details of its equity method investment, please refer to Part II, Item 8, Note 2 — Equity Method Investment in Equity Investee in its 2025 Form 10-K.

On July 14, 2025, the Company entered into an equity transfer agreement to sell approximately 20.3% of outstanding equity interest in the JV Company for an aggregate cash consideration of $150 million. On August 29, 2025, the amended shareholders’ agreement for the JV Company was signed, which reduced the Company’s equity interest in the JV Company by 20.3% to an ownership percentage of 18.9%. As a result, the Company received its first installment of RMB 676 million (or $94.5 million based on the currency exchange rate between RMB and U.S. Dollar on August 29, 2025), and paid transaction costs related to this sale of approximately $2.4 million. In addition, the Company received $11.1 million for the second installment payment during the three months ended December 31, 2025, and maintained a receivable balance of $46.1 million as of December 31, 2025, which is included in the receivable from sale of equity interest in the JV Company line on the Condensed Consolidated Balance Sheets. In January 2026, the Company also received $30.3 million for the third installment. The remaining installment will be received subject to satisfaction of certain conditions, which require the Company's continuing involvement, including voting in shareholder meetings to complete the transaction in accordance with the equity transfer agreement, plus other administrative actions. As a result of the sales transaction, the Company evaluated the factors that indicate the ability to exercise its significant influence to the JV Company, including but not limited to representation on the board, material intra-entity transactions, and participation in policy making process. The Company concluded that it continues to have the ability to exercise significant influence over the operating and financial policies of the JV Company and accordingly accounts for the investment using the equity method of accounting.

The Company 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 from the JV Company. During the three months ended December 31, 2025, the Company recorded a $0.1 million loss, using lag reporting. During the six months ended December 31, 2025, the Company recorded $1.3 million gain, including the $1.1 million gain on the related sale of a portion of its interest in the equity method investment and $0.2 million gain of its equity share of the JV Company, using lag reporting. During the three and six months ended December 31, 2024, the Company recorded a $0.6 million loss and a $1.6 million loss on its equity share of the JV Company, respectively, using lag reporting.

  1. Related Party Transactions

As of December 31, 2025, the Company owned approximately 18.9% equity interest in the JV Company, which, by definition, is a related party to the Company. The JV Company supplies 12-inch wafers and provides assembly and testing services to AOS. The JV Company reimbursed AOS for purchases made on its behalf of $1.0 million and $1.1 million for the three and six months ended December 31, 2025, respectively and $3.1 million and $5.3 million for the three and six months ended December 31, 2024, respectively. The purchases by AOS for the three and six months ended December 31, 2025 were $25.1 million and $55.4 million, respectively, and for the three and six months ended December 31, 2024 were $28.2 million and $56.5 million, respectively. Due to the right of offset of receivables and payables with the JV Company, as of December 31, 2025 and June 30, 2025, AOS recorded the net amount of $16.9 million and $15.8 million, respectively, as a payable related to equity investee, net, on the Condensed Consolidated Balance Sheet. During the three and six months ended December 31, 2025, the Company also recordednil and approximately $1.9 million, respectively, of other income for certain service the Company provided to the JV Company.

  1. 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.

Summarized below are individual customers whose revenue or accounts receivable balances were 10% or higher than the respective total consolidated amounts:

  1. Bank Borrowings

Accounts Receivable Factoring Agreement

On August 9, 2019, one of the Company's wholly-owned subsidiaries (the "Borrower") entered into a factoring agreement with the Hongkong and Shanghai Banking Corporation Limited (“HSBC”), whereby the Borrower assigns certain of its accounts receivable with recourse. This factoring agreement allows the Borrower to borrow up to 70% of the net amount of its eligible accounts receivable of the Borrower with a maximum amount of $30.0 million. The interest rate is based on the Secured Overnight Financing Rate ("SOFR"), plus 2.01% 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. In August 2025, this factoring agreement was terminated. As of December 31, 2025, there was no outstanding balance.

Debt financing

In September 2021, Jireh Semiconductor Incorporated (“Jireh”), one of the wholly-owned subsidiaries, entered into a financing arrangement agreement with a company (“Lender”) for the lease and purchase of a machinery equipment manufactured by a supplier. This agreement includes a payment term of five (5) years, pursuant to which Jireh commenced payments of interests and principal to the Lender in September 2022 when the final installation and acceptance of the equipment were completed. After the end of such payment term, Jireh has the option to purchase the equipment for $1. The implied interest rate was 4.75% per annum which was adjustable based on every five basis point increase in 60-month U.S. Treasury Notes. The total purchase price of this equipment was euro 12.0 million. In April 2021, Jireh made a down payment of euro 6.0 million, representing 50% of the total purchase price of the equipment, to the supplier. In June 2022, the equipment was delivered to Jireh after Lender paid 40% of the total purchase price, for euro 4.8 million, to the supplier on behalf of Jireh. In September 2022, Lender paid the remaining 10% payment for the total purchase price and reimbursed Jireh for the 50% down payment, after the installation and configuration of the equipment. The title of the equipment was transferred to Lender following such payment. The agreement was amended with fixed implied interest rate of 7.51% and monthly payment of principal and interest effective in October 2022. Other terms remain the same. In addition, Jireh purchased hardware for the machine under this financing arrangement. The purchase price of this hardware was $0.2 million. The financing arrangement is secured by this equipment and other equipment at Jireh, which had a net book value of $11.3 million as of December 31, 2025. As of December 31, 2025, the outstanding balance of this debt financing was $5.1 million.

Long-term bank borrowings

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 SOFR plus the applicable margin based on the outstanding balance of the loan. This agreement contains customary restrictive covenants and includes certain financial covenants that the Company is required to maintain. Jireh drew down $45.0 million on February 16, 2022 with the first payment of principal beginning in October 2022. As of June 30, 2025, Jireh was in compliance with these covenants and the outstanding balance of this loan was $20.3 million. In August 2025, the Company paid the outstanding balance in full and this agreement was terminated. As of December 31, 2025, there was no outstanding balance.

  1. Shareholders’ Equity and Share-based Compensation

Share Repurchase

In November 2025, the Board of Directors approved a new share repurchase program (the “Repurchase Program”) that authorizes 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 the reissuance 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 reissuance of treasury stock. Any

remaining balance of the losses is charged to retained earnings.

During the three and six months ended December 31, 2025, the Company repurchased an aggregate of 728,373 shares from the open market, for a total cost of $13.9 million, excluding fees and related expenses, at an average price of $19.12 per share. As of December 31, 2025, approximately $16.1 million remained available under the Repurchase Program.

The Company recorded approximately $1.1 million and $2.3 million of expenses, using the accelerated attribution method, for these PRSUs during the three and six months ended December 31, 2025, respectively, and $1.0 million and $1.9 million for the three and six months ended December 31, 2024, respectively.

The following table summarizes the Company’s PRSUs activities for the six months ended December 31, 2025:

As of December 31, 2025, total unrecognized compensation cost under the Company’s share-based compensation plans was $48.0 million, which is expected to be recognized over a weighted-average period of 2.0 years.

  1. Income Taxes

The Company recognized income tax expense of approximately $1.5 million and $1.2 million for the three months ended December 31, 2025 and 2024, respectively. The income tax expense of $1.5 million for the three months ended December 31, 2025 included a $0.1 million discrete tax expense. The income tax expense of $1.2 million for the three months ended December 31, 2024 included a $0.1 million discrete tax expense. Excluding the discrete income tax items, the income tax expense for the three months ended December 31, 2025 and 2024 was $1.4 million and $1.2 million, respectively, and the effective tax rate for the three months ended December 31, 2025 and 2024 was (12.0)% and (22.1)%, respectively. The changes in the tax expense and effective tax rate between the periods resulted primarily from changes in the mix of earnings in various geographic jurisdictions between the current period and the same period of last year.

The Company recognized income tax expense of approximately $3.4 million and $2.3 million for the six months ended December 31, 2025 and 2024, respectively. The income tax expense of $3.4 million for the six months ended December 31, 2025

included a $0.1 million discrete tax expense. The income tax expense of $2.3 million for the six months ended December 31, 2024

included a $0.1 million discrete tax expense. Excluding the discrete income tax items, income tax expense for the six months ended December 31, 2025 and 2024 was $3.3 million and $2.1 million, respectively, and the effective tax rate for the six months ended December 31, 2025 and 2024 was (27.3)% and (31.4)%, respectively. The changes in the tax expense and effective tax rate between the periods resulted primarily from changes in the mix of earnings in various geographic jurisdictions between the current year and the same period of last year, including reporting $0.7 million of income tax expense related to the Company’s income from its investment in CQJV for the six months ended December 31, 2025 versus an $0.2 million tax benefit for the six months ended December 31, 2024.

During the three months ended September 30, 2025, income tax payable increased by $10.4 million and deferred tax liability decreased by $10.5 million as a result of the sale of approximately 20.3% of the Company’s equity interest in the JV company for $150 million. The Company made income tax payments of approximately $8.7 million as a result of the sale transaction during the three months ended December 31, 2025.

The Company files its income tax returns in the United States and in various foreign jurisdictions. The tax years 2004 to 2025 remain open to examination by U.S. federal and state tax authorities. The tax years 2019 to 2025 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, 2025, the gross amount of unrecognized tax benefits was approximately $10.8 million, of which $7.5 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.

One Big Beautiful Bill Act, Enacted July 4, 2025

On July 4, 2025, H.R. 1, commonly known as the One Big Beautiful Bill Act (the “OBBB”), was signed into law. This includes significant changes to the federal corporate tax provisions and extends certain otherwise expiring provisions of the 2017 Tax Cuts and Jobs Act. The key provisions include allowing immediate expensing of domestic research and experimental expenditures, new limitations on interest expense deductibility, reinstatement of 100% bonus depreciation for qualified assets placed in service in the United States after January 19, 2025 as well as changes to the calculation of taxable income resulting from the foreign derived intangible income deduction. ASC 740 Income Taxes requires the effects of changes in tax rates and laws to be recognized in the period in which the relevant legislation is enacted. The Company has concluded that the impact of OBBB for the current quarter is immaterial.

  1. 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 Chief Executive Officer assesses performance of the Company, monitors budget versus actual results and determines how to allocate resources based on the consolidated net income or loss as reported on the Company’s Condensed Consolidated Statements of Income (Loss). There are no other expense categories regularly provided to the Chief Executive Officer that are not already included in the Condensed Consolidated Statements of Income (Loss). 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:

  1. Commitments and Contingencies

Purchase Commitments

As of December 31, 2025, the Company had approximately $61.0 million of outstanding purchase commitments primarily for purchases of semiconductor raw materials, wafers, spare parts, packaging and testing services and others, as well as $17.3 million of capital commitments for the purchase of property and equipment. Purchase commitments are generally restricted to a purchase forecast as mutually agreed between the parties. This purchase forecast can vary among different suppliers.

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.

The Company is a party to a variety of agreements 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, andno accrual was made at December 31, 2025 and June 30, 2025.

The Company has agreed to indemnify its directors and certain employees as permitted by law and pursuant to its By-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 a reasonable cost, if at all, in the future.
