Item 7.Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion of the financial condition and results of our operations in conjunction with our consolidated financial statements and the notes to those statements included elsewhere in this annual report. Our consolidated financial statements contained in this annual report are prepared in accordance with U.S. GAAP.

Overview

We are a designer, developer, and global supplier of a broad range of discrete power devices, wide band gap power devices, power management ICs and modules, including a wide portfolio of Power MOSFET, SiC, IGBT, IPM, TVS, HV Gate Drivers, Power IC, and Digital Power products. Our portfolio of power semiconductors includes approximately 2,800 products, and has grown with the introduction of over 100 new products in the fiscal year ended June 30, 2025, and over 100 and 60 new products in the fiscal years ended June 30, 2024 and 2023, respectively. Our teams of scientists and engineers have developed extensive intellectual properties and technical knowledge that encompass major aspects of power semiconductors, which we believe enables us to introduce and develop innovative products to address the increasingly complex power requirements of advanced electronics. We have an extensive patent portfolio that consists of 949 patents and 64 patent applications in the United States as of June 30, 2025. We also have a total of 961 foreign patents, which primarily were based on our research and development efforts through June 30, 2025. We differentiate ourselves by integrating our expertise in technology, design and advanced manufacturing and packaging to optimize product performance and cost. Our portfolio of products targets high-volume applications, including personal 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. During fiscal year 2025, we accelerated the development of new technology platforms which allowed us to introduce 33 medium and high voltage MOSFET products, targeting primarily the power supply markets and industrial markets, as well as 11 low voltage MOSFET products primarily for the communication market. In addition, we introduced 38 Power IC new products for computing applications, communication and consumer markets.

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

On March 29, 2016, we formed a joint venture (the “JV Company”) with two investment funds owned by the Municipality of Chongqing (the “Chongqing Funds”), for the purpose of constructing and operating a power semiconductor packaging, testing and 12-inch wafer fabrication facility (“Fab”) in the LiangJiang New Area of Chongqing, China. As of December 1, 2021, we owned 50.9%, and the Chongqing Funds owned 49.1% of the equity interest in the JV Company. The joint venture was accounted under the provisions of the consolidation guidance since we had controlling financial interests until December 1, 2021. In December 2021, we sold a portion of our equity interest in the JV Company to a third-party investor, pursuant to which we reduced our ownership from 50.9% to 48.8% of outstanding equity of the JV Company, and reduced our representation on the board of directors of the JV Company. As a result, the JV Company was deconsolidated from our consolidated financial statements effective as of December 2, 2021.

From December 2021 to June 2024, we completed several transactions to sell additional equity interests of the JV Company to third-party investors, while the JV Company also issued additional equity interests to new investors that diluted our ownership interest. Accordingly, as of June 30, 2024, the percentage of outstanding JV equity interest beneficially owned by us was further reduced to 42.8%.

On December 30, 2024, the JV Company signed an investment agreement with an investor, pursuant to which the investor agreed to invest RMB 500 million (or $68.5 million based on the currency exchange rate between RMB and U.S. Dollar on December 31, 2024) in the JV Company in exchange for a 7.09% interest. This transaction closed on January 15, 2025, at which time, the percentage of outstanding JV Company’s equity interest owned by the Company was reduced to approximately 39.2%. The funding of the investment was agreed to be made in three installments. The JV Company received the first installment of RMB 40 million (or $5.5 million) on December 31, 2024. However, the JV Company has not received the remaining two installments as of the filing date. As of June 30, 2025, the percentage of outstanding JV equity interest beneficially owned by the Company was 39.2%.

On July 14, 2025, we entered into an equity transfer agreement with a strategic investor to sell approximately 20.3% of outstanding equity interest in the JV Company for an aggregate cash consideration of $150 million to be paid in four installments, subject to satisfaction of certain conditions.

42

We expect to receive all four installment payments and close the transaction prior to the end of calendar year 2025. We believe this sale will provide additional and significant capital for us to continue investment in technology, R&D projects and acquisition of assets complementary to our business operations, which will facilitate and accelerate our efforts to develop and distribute innovative and diverse power semiconductor products to customers worldwide.

In addition, the JV Company will continue to provide us with significant level of foundry capacity to enable us to develop and manufacture our products. Pursuant to an agreement with the JV Company and other shareholders of the JV Company, the JV Company is committed to provide us with a specified level of monthly wafer production capacity.

Other Factors Affecting Our Performance

The global, regional economic and PC market conditions: Because our products primarily serve consumer electronic applications, any significant changes in global and regional economic conditions could materially affect our revenue and results of operations. A significant amount of our revenue is derived from sales of products in the PC markets, such as notebooks, motherboards and notebook battery packs. Therefore, a substantial decline in the PC market could have a material adverse effect on our revenue and results of operations. The PC markets have experienced a modest global decline in recent years due to continued growth of demand in tablets and smart phones, worldwide economic conditions and the industry inventory correction which had and may continue to have a material impact on the demand for our products. In addition, the PC market may be affected by evolving laws and regulations governing international trade, such as export control regulations.

A decline of the PC market may have a negative impact on our revenue, factory utilization, gross margin, our ability to resell excess inventory, and other performance measures. We have executed and continue to execute strategies to diversify our product portfolio, penetrate other market segments, including the consumer, communications and industrial markets, and improve gross margins and profit by implementing cost control measures. While making efforts to reduce our reliance on the computing market, we continue to support our computing business and capitalize on the opportunities in this market with a more focused and competitive PC product strategy to gain market share.

Manufacturing costs and capacity availability: Our gross margin is affected by a number of factors including our manufacturing costs, utilization of our manufacturing facilities, the product mixes of our sales, pricing of wafers from third party foundries and pricing of semiconductor raw materials. Capacity utilization affects our gross margin because we have certain fixed costs at our Shanghai facilities and our Oregon Fab. If we are unable to utilize our manufacturing facilities at a desired level, our gross margin may be adversely affected. In addition, from time to time, we may experience wafer capacity constraints, particularly at third party foundries, that may prevent us from meeting fully the demand of our customers. While we can mitigate these constraints by increasing and re-allocating capacity at our own fab, we may not be able to do so quickly or at sufficient level, which could adversely affect our financial conditions and results of operations. We also rely on third parties to provide foundry capacity to manufacture our products, including the JV Company, therefore it is important that we maintain continuous access to such capacity, which may not be available at sufficient level or at pricing terms favorable. If these third-party foundries, including the JV Company, take actions or make decisions that prevent us from accessing required capacity, our operations may be adversely affected.

Erosion and fluctuation of average selling price: Erosion of average selling prices of established products is typical in our industry. Consistent with this historical trend, we expect our average selling prices of our existing products to decline in the future. However, in the normal course of business, we seek to offset the effect of declining average selling price by introducing new and higher value products, expanding existing products for new applications and new customers and reducing the manufacturing cost of existing products. These strategies may cause the average selling price of our products to fluctuate significantly from time to time, thereby affecting our financial performance and profitability.

Product introductions and customers’ product requirements: Our success depends on our ability to introduce products on a timely basis that meet or are compatible with our customers' specifications and performance requirements, including our Tier 1 customers who often have stringent requirements. Both factors, timeliness of product introductions and conformance to customers' requirements, are equally important in securing design wins with our customers. As we accelerate the development of new technology platforms, we expect to increase the pace at which we introduce new products and seek and acquire design wins. If we were to fail to introduce new products on a timely basis that meet customers’ specifications and performance requirements, particularly those products with major OEM customers, and continue to expand our serviceable markets, then we would lose market share and our financial performance would be adversely affected.

Distributor ordering patterns, customer demand and seasonality: Our distributors place purchase orders with us based on their forecasts of end customer demand, and this demand may vary significantly depending on the sales outlook and market and economic conditions of end customers. Because these forecasts may not be accurate, channel inventory held at our distributors may fluctuate significantly, which in turn may prompt distributors to make significant adjustments to their purchase orders

43

placed with us. As a result, our revenue and operating results may fluctuate significantly from quarter to quarter. In addition, because our products are used in consumer electronics products, our revenue is subject to seasonality. Our sales seasonality is affected by numerous factors, including global and regional economic conditions as well as the PC market conditions, revenue generated from new products, changes in distributor ordering patterns in response to channel inventory adjustments and end customer demand for our products and fluctuations in consumer purchase patterns prior to major holiday seasons. Typically, we generate lower revenue during the first quarter of the calendar year as compared to other quarters. However, broad fluctuations in the semiconductor markets and the global and regional economic conditions, in particular the changing PC market conditions, have had a more significant impact on our results of operations than seasonality. Furthermore, our revenue may be impacted by the level of demand from our major customers due to factors outside of our control. If these major customers experience significant decline in the demand of their products, encounter difficulties or defects in their products, or otherwise fail to execute their sales and marketing strategies successfully, it may adversely affect our revenue and results of operations.

Principal line items of statements of operations

The following describes the principal line items set forth in our consolidated statements of operations:

Revenue

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

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

In February 2023, we entered into a license agreement with a customer to license our proprietary SiC technology and provided 24-months of engineering and development services for a total fee of $45.0 million. The license and development fee required significant integration to create a combined output to the customer and was determined to be one performance obligation and was recognized over the 24 months during which we performed the engineering and development services. We use the input method to measure progress and recognize revenue, based on the effort expended relative to the estimated total effort to satisfy the performance obligation. During the fiscal years ended June 30, 2025, 2024 and 2023, we recorded $13.8 million, $21.2 million and $9.9 million of license and development revenue, respectively. As of June 30, 2025, all revenue has been recognized and all consideration has been received associated with the license agreement, therefore we no longer have any obligations under the license agreement. We also entered into an accompanying supply agreement to provide limited wafer supply to the customer.

Cost of goods sold

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

Operating expenses

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

44

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

Selling, general and administrative expenses.Our selling, general and administrative expenses consist primarily of salaries, bonuses, benefits, share-based compensation expense, product promotion costs, occupancy costs, travel expenses, expenses related to sales and marketing activities, amortization of software, depreciation of equipment, maintenance costs, other expenses for general and administrative functions, and costs for outside professional services, including legal, audit and accounting services, as well as impairment of long-lived assets. We review all long-lived assets whenever events or changes in circumstance indicate that these assets may not be recoverable. When evaluating long-lived assets, if we conclude that the estimated undiscounted cash flows attributable to the assets are less than their carrying value, we recognize an impairment loss based on the excess of the carrying amount of the assets over their respective fair values. We expect our selling, general and administrative expenses to fluctuate in the near future as we continue to exercise cost control measures.

Income tax expense

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

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

Bermuda Corporate Income Tax for Tax Years Beginning in 2025

The Company is subject to income tax expense or benefit based upon pre-tax income or loss reported in the consolidated statements of income (loss) and the provisions of currently enacted tax laws. The parent company is incorporated under the laws of Bermuda and is subject to Bermuda law with respect to taxation. Under current Bermuda law, the Company is not subject to any income or capital gains taxes in Bermuda. As we have previously disclosed, the Government of Bermuda announced in December 2023 that it enacted the Corporate Income Tax Act 2023, potentially imposing a 15% corporate income tax (CIT) on Bermuda companies that are within the scope of the CIT, that will be effective for tax years beginning on or after January 1, 2025. In particular, the CIT applies to multinational companies with annual revenue of 750 million euros or more in the consolidated financial statements of the ultimate parent entity for at least two of the four fiscal years immediately preceding the fiscal year when the CIT may apply.

The Company did not generate more than 750 million euro revenue in any of the four fiscal years before the tax year starting July 1, 2025. The Company continues to monitor and assess if and when it may be within the scope of the CIT. If we become subject to the Bermuda CIT, we may be subject to additional income taxes, which may adversely affect our financial position, results of operations and our overall business.

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

45

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 OBBB was enacted after the June 30, 2025 year end. As of June 30, 2025, we are continuing to assess the potential impact of the OBBB.

Equity method investment loss

We use the equity method of accounting when we have the ability to exercise significant influence, but we do not have control, as determined in accordance with generally accepted accounting principles, over the operating and financial policies of the company. Effective December 2, 2021, we reduced our equity interest in the JV Company below 50% of outstanding equity ownership and experienced a loss of control of the JV Company. As a result, we record our investment under equity method of accounting. Since we are unable to obtain accurate financial information from the JV Company in a timely manner, we record our share of earnings or losses of the JV Company on a one quarter lag.

We record our interest in the net earnings of the equity method investee, along with adjustments for unrealized profits or losses on intra-entity transactions and amortization of basis differences, within earnings or loss from equity interests in the Consolidated Statements of Operations. Profits or losses related to intra-entity sales with the equity method investee are eliminated until realized by the investor or investee. Basis differences represent differences between the cost of the investment and the underlying equity in net assets of the investment and are generally amortized over the lives of the related assets that gave rise to them. Equity method goodwill is not amortized. Instead the total equity method investment balance, including equity method goodwill, is tested for impairment.

On December 30, 2024, the JV Company signed an investment agreement with an investor, pursuant to which the investor agreed to invest RMB 500 million (or $68.5 million based on the currency exchange rate between RMB and U.S. Dollar on December 31, 2024) in the JV Company in exchange for a 7.09% interest. This transaction closed on January 15, 2025, at which time, the percentage of outstanding JV Company’s equity interest owned by the Company was reduced to approximately 39.2%. We recorded a gain of $0.5 million on the change of equity interest in the JV Company, which was included in the equity method investment loss line in the consolidated statements of operations. The funding of the investment was agreed to be made in three installments. The JV Company received the first installment of RMB 40 million (or $5.5 million) on December 31, 2024. However, the JV Company has not received the remaining two installments as of the filing date.

On July 14, 2025, we entered into an equity transfer agreement (“Agreement”) with the investor to sell approximately 20.3% of outstanding equity interest in the JV Company for an aggregate cash consideration of $150 million. We identified the negotiations of the equity transfer agreement throughout the fourth quarter of fiscal year 2025 as an impairment indicator and performed a quantitative impairment test as of June 30, 2025. Based on the implied valuation of the JV Company per the transaction price in the equity transfer agreement, the fair value of the equity method investment was determined to be lower than its carrying value, and a $76.8 million other-than-temporary impairment of the equity method investment was recognized as of June 30, 2025. The impairment loss is recorded within equity method investment loss in the consolidated statement of operations for the fiscal year ended June 30, 2025.

Results of Operations

A discussion of our results of operations for the fiscal year ended June 30, 2025 to June 30, 2024 is included below. For a discussion and comparison of the results of our operations for the fiscal year ended June 30, 2024 with the fiscal year ended June 30, 2023, refer to “Management’s Discussion and Analysis of Financial Conditions and Results of Operations” in our Form 10-K for the fiscal year ended June 30, 2024 filed with the SEC on August 23, 2024.

The following is a summary of revenue by end market:

Year Ended June 30, Change

(in thousands) (in thousands) (in percentage)

Total revenue was $696.2 million for fiscal year 2025, an increase of $38.9 million, or 5.9%, as compared to $657.3 million for fiscal year 2024. The increase was primarily due to an increase of $23.4 million and $24.1 million in sales of power discrete products and power IC products, respectively, offset by a decrease of $1.2 million in sales of packaging and testing services and other, as well as a decrease of $7.4 million in license and development services. The increase in power discrete and power IC product sales was primarily due to a 17.1% increase in unit shipments, offset by an 8.0% decrease in average selling price as compared to last fiscal year due to a shift in product mix. The decrease in revenue from packaging and testing services and other for fiscal year 2025 as compared to the last fiscal year was primarily due to decreased demand. The decrease in license and development services for the fiscal year 2025 was related to the license agreement with a customer to license our proprietary SiC technology and provided 24-month engineering and development services, which was completed in February 2025.

Cost of goods sold was $535.2 million for fiscal year 2025, an increase of $49.8 million, or 10.3%, as compared to $485.4 million for fiscal year 2024. The increase was primarily due to 5.9% increase in revenue. Gross margin decreased by 3.1 percentage points to 23.1% for fiscal year 2025, as compared to 26.2% for fiscal year 2024. The decrease in gross margin was primarily due to average selling pricing erosion, higher material costs and less favorable product mix during fiscal year ended June 30, 2025. We expect our gross margin to continue to fluctuate in the future as a result of variations in our product mix, semiconductor wafer and raw material pricing, manufacturing labor cost and general economic and PC market conditions.

Research and development expenses

Year Ended June 30, Change

(in thousands) (in thousands) (in percentage)

Research and development expenses were $94.3 million for fiscal year 2025, an increase of $4.3 million, or 4.8%, as compared to $89.9 million for fiscal year 2024. The increase was primarily attributable to a $2.9 million increase in share-based compensation as a result of a modification of market-based restricted stock units in August 2024, a $0.9 million increase in employee compensation and benefit expense mainly due to increased headcount, higher medical insurance expenses and higher severance expenses, a $0.3 million increase in product prototyping engineering expense as a result of increased engineering activities, as well as a $0.1 million increase in office rent expenses. We continue to evaluate and invest resources in developing new technologies and products utilizing our own fabrication and packaging facilities. We believe the investment in research and development is important to meet our strategic objectives.

Selling, general and administrative expenses

Year Ended June 30, Change

(in thousands) (in thousands) (in percentage)

Selling, general and administrative expenses were $95.2 million for fiscal year 2025, an increase of $9.4 million, or 11.0%, as compared to $85.7 million for fiscal year 2024. The increase was primarily attributable to a one-time settlement fee of $4.3 million for the export control investigation case, a $4.2 million increase in share-based compensation expense as a result of a modification of market-based restricted stock units in August 2024, and a $2.4 million increase in employee compensation and benefits expenses mainly due to merit-based compensation increases for certain personnel, higher insurance expenses and higher severance expenses, offset by a $0.8 million decrease in audit fees, a $0.7 million decrease in consulting fees, a $0.5 million decrease in marketing related expenses, and a $0.6 million decrease in allocation expenses. In addition, during the fiscal year ended June 30, 2025, we identified certain purchased manufacturing equipment that we were unable to meet our production process requirements. Because the equipment had no alternative uses, we recorded an impairment of $1.0 million related to such equipment.

Other loss, net

Year Ended June 30, Change

(in thousands) (in thousands) (in percentage)

Other loss, net increased by $0.9 million in fiscal year 2025 as compared to the last fiscal year primarily due to increase in foreign currency exchange loss as a result of the appreciation of RMB and Taiwan dollar against the U.S. dollar.

Interest income

49

Year Ended June 30, Change

(in thousands) (in thousands) (in percentage)

Interest income decreased by $0.9 million in fiscal year 2025 as compared to fiscal year 2024 primarily due to a result of lower interest rate and lower cash balance during fiscal year 2025.

Interest expenses

Year Ended June 30, Change

(in thousands) (in thousands) (in percentage)

Interest expenses decreased by $1.3 million in fiscal year 2025 as compared to fiscal year 2024 primarily due to less outstanding loan balance during fiscal year 2025.

Equity method investment loss

Year Ended June 30, Change

(in thousands) (in thousands) (in percentage)

On December 30, 2024, the JV Company signed an investment agreement with an investor, pursuant to which the investor agreed to invest RMB 500 million (or $68.5 million based on currency exchange rate between RMB and U.S. dollar on December 31, 2024) in the JV Company. This transaction closed on January 15, 2025, at which time, the percentage of outstanding JV Company’s equity interest owned by the Company was reduced to approximately 39.2%. As such, we recorded a gain of $0.5 million on the change of equity interest in the JV Company during fiscal year ended June 30, 2025.

On July 14, 2025, we entered into an equity transfer agreement with the investor to sell approximately 20.3% of outstanding equity interest in the JV Company for an aggregate cash consideration of $150 million. We identified the negotiations of the equity transfer agreement throughout the fourth quarter of fiscal year 2025 as an impairment indicator and performed a quantitative impairment test as of June 30, 2025. Based on the implied valuation of the JV Company per the transaction price in the equity transfer agreement, the fair value of the equity method investment was determined to be lower than its carrying value, and a $76.8 million other-than-temporary impairment of the equity method investment was recognized as of June 30, 2025.

Income tax expense

Year Ended June 30, Change

(in thousands) (in thousands) (in percentage)

Income tax expense (benefit) for fiscal years 2025 and 2024 was $(8.6) million and $3.6 million, respectively. Income tax expense decreased by $12.3 million in fiscal year 2025 as compared to fiscal year 2024. The decrease was primarily related to the tax benefits reported in connection with the Company’s investment in the JV Company. In fiscal year 2025, the Company reported a $77.8 million equity method investment loss, generating a $12.5 million tax benefit in fiscal year 2025 as compared to a $4.8 million equity method investment loss in fiscal year 2024 that generated a $0.7 million tax benefit in fiscal year 2024. Excluding the $12.5 million tax benefit related to the $77.8 million of equity method loss in fiscal 2025, the fiscal 2025 tax

50

would be $3.9 million of income tax expense. The remaining difference in tax expense between fiscal years 2025 and 2024 was primarily due to changes in various book-tax permanent differences, discrete tax adjustments between the two years, and changes in the mix of earnings in various geographic jurisdictions between the current year and the same period of last year.

The income tax benefit of $8.6 million for the year ended June 30, 2025 also included a $0.2 million discrete tax benefit and the income tax expense of $3.6 million for the year ended June 30, 2024 included a $0.2 million discrete tax expense. Excluding the discrete income tax items, the effective tax rate for the years ended June 30, 2025 and 2024 was 30.4% and (130.6%), respectively.

51

Liquidity and Capital Resources

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

In September 2021, Jireh Semiconductor Incorporated (“Jireh”), one of the Company’s 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 has a 5 years term, after which 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, until the final installation and acceptance of the equipment. 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 which had a carrying amount of $12.1 million as of June 30, 2025. As of June 30, 2025, the outstanding balance of this debt financing was $6.5 million.

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 term of 5.5 years and matures on February 16, 2027. Jireh is required to make consecutive quarterly payments of principal and interest. The loan accrues interest based on the 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.

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 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. As of June 30, 2025, there was no outstanding balance for this loan.

The Chinese government imposes certain currency exchange controls on cash transfers out of China. Regulations in China permit foreign owned entities to freely convert the RMB into foreign currency for transactions that fall under the “current account,” which includes trade related receipts and payments, interests, and dividend payments. Accordingly, subject to the review and verification of the underlying transaction documents and supporting documents by the account banks in China, our Chinese subsidiaries may use RMB to purchase foreign exchange currency for settlement of such “current account” transactions without the pre-approval from SAFE or its provincial branch. Pursuant to applicable regulations, foreign-invested enterprises in China may pay dividends only out of their accumulated profits, if any, determined in accordance with Chinese accounting standards and regulations. A Chinese company must pay 10% of its annual after-tax profits to fund its statutory reserve fund unless it has reached 50% of the registered capital of the company. Where the accumulative amount of the company’s statutory reserve is not enough to make up for the losses of the previous year, the current year’s profits must first be used to make up for the losses before the statutory reserve is accrued. While SAFE approval is not statutorily required for eligible dividend payments to the foreign parent, in practice, before making the dividend payment, the account bank may seek SAFE’s opinion with respect to a dividend payment if the payment involves a relatively large amount, which may delay the dividend payment depending on the then overall status of cross-border payments and receipts of China.

Transactions that involve conversion of RMB into foreign currency in relation to foreign direct investments and provision of debt financings in China are classified as “capital account” transactions. Examples of “capital account” transactions include repatriations of investments by foreign owners and repayments of loan principal to foreign lenders. "Capital account"

52

transactions require prior approval from SAFE or its provincial branch or an account bank delegated by SAFE to convert a remittance into a foreign currency, such as U.S. dollars, and transmit the foreign currency outside of China. As a result of this and other restrictions under PRC laws and regulations, our China subsidiaries are restricted in their ability to transfer a portion of their net assets to us, and such restriction may adversely affect our ability to generate sufficient liquidity to fund our operations or other expenditures. As of June 30, 2025 and 2024, such restricted portion amounted to approximately $93.9 million and $93.5 million, or 11.4% and 10.5%, of our total consolidated net assets attributable to the Company, respectively.

As disclosed above, in July 2025, we entered into an equity transfer agreement with a third-party strategic investor to sell approximately 20.3% of outstanding equity interest in the JV Company for an aggregate cash consideration of $150 million to be paid in four installments, provided that certain conditions are satisfied. We expect to receive all four payments by the end of calendar year 2025, and the majority of the consideration, approximately $94 million, is expected to be paid in the first installment, which we anticipate to receive during the quarter ending September 30, 2025. We plan to use the cash proceeds from the sale to invest in technology, R&D projects and acquisition of assets complimentary to our business operations. See also “Risk Factors—Our recent sale of equity interest in the JV Company is subject to certain closing conditions, and if the conditions are not met, we may not receive a portion or any of the cash proceeds from the sale”.

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

Cash, cash equivalents and restricted cash

As of June 30, 2025 and 2024, we had $153.5 million and $175.5 million of cash, cash equivalents and restricted cash, respectively. Our cash, cash equivalents and restricted cash primarily consisted of cash on hand, restricted cash and short-term bank deposits with original maturities of three months or less. Of the $153.5 million and $175.5 million cash and cash equivalents, $40.7 million and $55.0 million, respectively, were deposited with financial institutions outside the United States.

The following table shows our cash flows from operating, investing and financing activities for the periods indicated:

Year Ended June 30,

(in thousands)

Net cash provided by operating activities $ 29,668 $ 25,710

Net cash used in investing activities (36,441) (35,744)

Net cash used in financing activities (15,496) (9,903)

Net decrease in cash, cash equivalents and restricted cash $ (22,042) $ (20,063)

Cash flows from operating activities

For the fiscal year ended June 30, 2025, the $4.0 million increase in cash provided by operating activities compared to the fiscal year ended June 30, 2024 was primarily due to an increase of net loss of $85.9 million and an increase of non-cash expenses of $78.3 million, a decrease of $18.6 million in inventory purchases, an increase of accounts payable of $15.7 million primarily due to timing of payment, an increase of $6.9 million in accrued and other liabilities, an increase of $2.9 million in deferred revenue, an increase of $1.6 million in income tax payable, offset by an increase of $32.1 million in accounts receivable due to timing of billings and collection of payments, and an increase of $2.4 million in other current and long term assets due to increase in advance payments to suppliers.

Cash flows from investing activities

For the fiscal year ended June 30, 2025, the $0.7 million increase in cash used in investing activities compared to the fiscal year ended June 30, 2024 was primarily due to a $0.1 million increase in purchases of property and equipment, a $0.3

53

million decrease in the proceeds of sales of property and equipment, as well as a $0.3 million decrease in government grants related to equipment.

Cash flows from financing activities

For the fiscal year ended June 30, 2025, the $5.6 million increase in cash used in financing activities compared to the fiscal year 2024 was primarily due to $2.3 million decrease in proceeds from exercise of stock options and the Employee Share Purchase Plan (“ESPP”), and $3.0 million increase in withholding tax paid on behalf of employees for net share settlement.

Critical Accounting Estimates

General

Our accounting policies are more fully described in Note 1 of the Notes to the consolidated financial statements contained in this Annual Report on Form 10-K. As disclosed in Note 1, the preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events that affect the amounts reported in the financial statements and accompanying notes. Management believes it is unlikely that applying other estimates and assumptions would have a material impact on the financial statements. We consider the following accounting policies to be those that are most important to the portrayal of our financial condition and that require a higher degree of judgment.

Revenue recognition

We determine 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. We recognize 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 we expect to provide to certain distributors. We present revenue net of sales taxes and any similar assessments. Our standard payment terms range from 30 to 60 days.

We sell our products primarily to distributors, who in turn sell the products globally to various end customers. Sales to most distributors are made under terms allowing certain price adjustments of the Company’s products held in their inventory or upon sale to their end customers. Revenue from sales to distributors is recognized upon the transfer of control to the distributor. In the ordinary course of business, our distributors may need to sell our products to end customers at prices below the standard distribution price in order to remain competitive and secure sales. After the distributors sell the Company’s products to their end customers, the distributors submit a “ship-and-debit” price adjustment claim to the Company to adjust the distributor’s cost from the standard price to the pre-approved lower price. After the Company verifies that the claim was pre-approved, a credit memo is issued to the distributors for the ship-and-debit claim. In determining the transaction price, the Company considers ship-and-debit price adjustments to be variable consideration. The Company estimates the variable consideration of the allowance for price adjustments at the time revenue is recognized. Estimating the allowance for price adjustments requires management to make certain assumptions including distributor inventory levels, forecasted distributor selling prices, distributor margins and future demand for products. These assumptions could be affected by current and future economic and market conditions. We also allow 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. We record an allowance for stock rotation returns based on historical returns, expected sales volumes and individual distributor agreements. 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.

Valuation of inventories

We evaluate our inventory for salability, obsolescence and other available applicable information. When evaluating the adequacy of our provision for excess and obsolete inventory, we identify excess and obsolete products and also analyze historical usage, forecasted demand, and current economic trends. Demand for our products can fluctuate significantly from period to period. A significant decrease in demand could result in an increase in the amount of excess inventory on hand. In addition, our industry is characterized by frequent new product development and technological changes that could result in an increase in the amount of obsolete inventory quantities on hand. Also our estimates of forecasted demand and judgement to determine excess inventory may prove to be inaccurate, in which case we may have understated or overstated the reduction to the total carrying value of our inventory for excess and obsolete inventory. If actual economic trends are less favorable than those forecasted, additional future inventory write-downs may be required, which could adversely affect our operating results. Inventory adjustments, once established, are not reversed until the related inventory has been sold or scrapped. If actual economic trends are more favorable than expected and the products that have previously been written down are sold, our gross margin would be favorably impacted.

Recently Issued Accounting Pronouncements

See Note 1 of the Notes to the consolidated financial statements contained in this Annual Report on Form 10-K for a full description of recent accounting pronouncements, including the expected dates of adoption and estimated effects on results of operations and financial condition.

Item 7A.Quantitative and Qualitative Disclosures About Market Risk

Foreign currency risk

We and our principal subsidiaries use U.S. dollars as our functional currency because most of the transactions are conducted and settled in U.S. dollars. All of our revenue and a significant portion of our operating expenses are denominated in U.S. dollars. The functional currency for our in-house packaging and testing facilities in China is U.S. dollars and a significant portion of our capital expenditures are denominated in U.S. dollars. However, foreign currencies are required to fund our overseas operations, primarily in Taiwan and China. Operating expenses of overseas operations are denominated in their respective local currencies. In order to minimize exposure to foreign currencies, we maintained cash and cash equivalent balances in foreign currencies, including Chinese Yuan as operating funds for our foreign operating expenses. For our subsidiaries which use the local currency as the functional currency, the 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. Our management believes that our exposure to foreign currency translation risk is not significant based on a 10% sensitivity analysis in foreign currencies due to the fact that the net assets denominated in foreign currencies pertaining to foreign operations, principally in Taiwan and China, are not significant to our consolidated net assets.

Interest rate risk

Our interest-bearing assets comprise mainly interest-bearing short-term bank balances. We manage our interest rate risk by placing such balances in instruments with various short-term maturities. Borrowings expose us to interest rate risk. Borrowings are drawn down after due consideration of market conditions and expectation of future interest rate movements. As of June 30, 2025, we had $26.7 million outstanding under our loan and $2.3 million outstanding under our financing leases, which were subject to fluctuations in interest rates. For the year ended June 30, 2025, a hypothetical 10% increase in the interest rate could result in $0.1 million additional annual interest expense. The hypothetical assumptions made above will be different from what actually occurs in the future. Furthermore, the computations do not anticipate actions that may be taken by our management should the hypothetical market changes actually occur over time. As a result, actual impacts on our results of operations in the future will differ from those quantified above.

Commodity Price Risk

We are subject to risk from fluctuating market prices of certain commodity raw materials, particularly gold and silver, that are used in our manufacturing process and incorporated into our end products. Supplies for such commodities may from time-to-time become restricted, or general market factors and conditions may affect the pricing of such commodities. Over the past few years, the price of gold increased significantly and certain of our supply chain partners assess surcharges to compensate for the rising commodity prices. We have been converting some of our products to use copper wires instead of gold wires. Our results of operations may be materially and adversely affected if we have difficulty obtaining these raw materials, the quality of available raw materials deteriorates, or there are significant price changes for these raw materials. For periods in which the prices of these raw materials are rising, we may be unable to pass on the increased cost to our customers which would result in decreased margins for the products in which they are used and could have a material adverse effect on our net earnings. We also may need to record losses for adverse purchase commitments for these materials in periods of declining prices. We do not enter into formal hedging arrangements to mitigate against commodity risk. We estimate that a 10% increase or decrease in the costs of raw materials subject to commodity price risk, such as gold and silver, would decrease or increase our current year's net earnings by $1.0 million, assuming that such changes in our costs have no impact on the selling prices of our products and that we have no pending commitments to purchase metals at fixed prices.

Item 9A.Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2025, the end of the period covered by this Annual Report on Form 10-K. Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) are designed to provide reasonable assurance that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to a company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

Based upon that evaluation as of the end of the period covered in this Annual Report on Form 10-K, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2025.

Management’s Annual Report on Internal Control over Financial Reporting

Our management, including our Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements for external purposes in accordance with generally accepted accounting principles, and includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are made only in accordance with authorizations of our management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.

Our management conducted an assessment of the effectiveness of our internal control over financial reporting based on the criteria set forth in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), as amended from time to time. Based on the assessment, our management concluded that the Company's internal control over financial reporting was effective as of June 30, 2025.

The effectiveness of the Company’s internal control over financial reporting as of June 30, 2025 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report included in this Annual Report on Form 10-K.

Changes in Internal Control Over Financial Reporting

As required by Rule 13a-15(d) under the Exchange Act, our management, including our Chief Executive Officer and Chief Financial Officer, evaluated our internal control over financial reporting to determine whether any changes occurred during the fourth fiscal quarter covered by this Form 10-K that have materially affected or are reasonably likely to materially affect, our internal control over financial reporting. Based on that evaluation, there were no changes during the fourth fiscal quarter ended June 30, 2025.

Inherent Limitations on the Effectiveness of Controls

While our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance that their respective objectives will be met, we do not expect that our disclosure controls and procedures or our internal control over financial reporting are or will be capable of preventing or detecting all errors and all fraud. Any

57

control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Alpha and Omega Semiconductor Limited:

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Alpha and Omega Semiconductor Limited and subsidiaries (the "Company") as of June 30, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of June 30, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended June 30, 2025, of the Company and our report dated August 28, 2025, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Alpha and Omega Semiconductor Limited:

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of Alpha and Omega Semiconductor Limited and subsidiaries (the "Company") as of June 30, 2025, the related consolidated statements of operations, comprehensive income (loss), equity, and cash flows, for the year ended June 30, 2025, and the related notes and the schedules listed in the Index at Item 15 (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of June 30, 2025, and the results of its operations and its cash flows for the year ended June 30, 2025, in conformity with the accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of June 30, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated August 28, 2025, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Inventories — Excess and Obsolete Inventory Reserve — Refer to Note 1 to the financial statements

Critical Audit Matter Description

The Company evaluates the adequacy of the excess and obsolete inventory reserve based upon a review of inventory quantities on hand compared to forecasted demand. Management’s estimates of forecasted demand are based upon analysis and assumptions including, but not limited to, historical usage, sales forecasts, customer backlog, and projected and current economic trends.

We identified the excess and obsolete inventory reserve as a critical audit matter due to the significant assumptions management makes with regards to estimating the forecasted demand. This required a high degree of auditor judgement and an increased extent of effort when performing audit procedures to evaluate the reasonableness of management's estimates of forecasted demand.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to management’s estimates of forecasted demand used in the excess and obsolete inventory reserve included the following, among others:

63

•We tested the effectiveness of internal controls over management’s review of the excess and obsolete inventory reserve, including internal controls designed to review and approve forecasted demand and the underlying assumptions regarding historical usage, sales forecasts, customer backlog, and projected and current economic trends.

•We evaluated management’s ability to accurately estimate forecasted demand by selecting a sample of inventory products as of June 30, 2024, and comparing usage in the current year to forecasted demand estimates made in the prior year.

•We selected a sample of inventory products as of June 30, 2025, and tested the forecasted demand by comparing internal and external information (e.g. historical usage, customer backlog, communications with customers, expected product lifecycles, economic trends, and inquiries with sales personnel, as applicable) with the Company’s forecasted demand.

•We considered, when relevant, the existence of contradictory evidence based on reading of internal communications to management and the board of directors, Company press releases, and analyst reports, as well as our observations and inquiries as to changes within the business and obtained through other areas of the audit.

ALPHA AND OMEGA SEMICONDUCTOR LIMITED

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

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 consolidated financial statements include the accounts of all subsidiaries. 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.

Equity Method Investment Loss

The Company uses the equity method of accounting when it has the ability to exercise significant influence, but not control, as determined in accordance with generally accepted accounting principles, over the operating and financial policies of the investee. Effective December 1, 2021, the Company reduced its equity interest in the JV Company and no longer controlled the JV Company. As a result, beginning December 2, 2021, the Company recorded its investment under the equity method of accounting. Since the Company is unable to obtain accurate financial information from the JV Company in a timely manner, the Company’s share of earnings or losses of the JV Company is recorded on a one quarter lag. The Company discloses and recognizes intervening events at the JV Company in the lag period that could materially affect its consolidated financial statements, if applicable.

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

From December 2021 to June 2024, the Company completed several transactions to sell additional equity interests of the JV Company to third-party investors, while the JV Company also issued additional equity interests to new investors that diluted the Company's ownership interest. Accordingly, as of June 30, 2024, the percentage of outstanding JV equity interest beneficially owned by the Company was further reduced to 42.8%. On December 30, 2024, the JV Company signed an investment agreement with an investor, pursuant to which the investor agreed to invest RMB 500 million (or $68.5 million based on the currency exchange rate between RMB and U.S. Dollar on December 31, 2024) in the JV Company in exchange for a 7.09% interest. This transaction closed on January 15, 2025, at which time, the percentage of outstanding JV Company’s equity interest owned by the Company was reduced to approximately 39.2%. The Company recorded a gain of $0.5 million on the change of equity interest in the JV Company, which was included in the equity method investment loss line in the consolidated statements of operations. The funding of the investment was agreed to be made in three installments. The JV Company received the first installment of RMB 40 million (or $5.5 million) on December 31, 2024. However, the JV

72

Company has not received the remaining two installments as of the filing date. As of June 30, 2025, the percentage of outstanding JV equity interest beneficially owned by the Company was 39.2%.

In the fourth quarter of fiscal year 2025, the Company began negotiations with a third-party strategic investor to sell a portion of its outstanding equity interest in the JV Company. On July 14, 2025, the Company entered into an equity transfer agreement (“Agreement”) with the investor to sell approximately 20.3% of outstanding equity interest in the JV Company for an aggregate cash consideration of $150 million. The Company identified the negotiations of the equity transfer agreement throughout the fourth quarter of fiscal year 2025 as an impairment indicator and performed a quantitative impairment test as of June 30, 2025. Based on the implied valuation of the JV Company per the transaction price in the equity transfer agreement, the fair value of the equity method investment was determined to be lower than its carrying value, and a $76.8 million other-than-temporary impairment of the equity method investment was recognized as of June 30, 2025.The impairment loss is recorded within Equity method investment loss in the consolidated statement of operations for the 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, recoverability of and useful lives for property, plant and equipment.

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 by the local custom authority 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, 2025 and 2024, 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

73

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. Level 2 inputs were used to estimate the fair value of the equity method investment for the purpose of recognizing the other than temporary impairment recorded in 2025. 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. The Company evaluated its inventory for salability, obsolescence and other available applicable information. When evaluating the adequacy of its provision for excess and obsolete inventory, the Company identifies excess and obsolete products and also analyzes historical usage, forecasted demand, and current economic trends. If actual economic trends are less favorable than those forecasted, additional future inventory write-downs may be required, which could adversely affect our operating results. Inventory adjustments, once established, are not reversed until the related inventory has been sold or scrapped.

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

74

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 are expected to 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 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 to five years starting from the date when it is ready for its intended use.

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, 2025 and 2024, the Company reduced property, plant and equipment by $0.7 million and $1.0 million, respectively. 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.

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.

During the fiscal year ended June 30, 2025, the Company identified certain purchased manufacturing equipment that was unable to meet its production process requirements. Because the equipment had no alternative uses, the Company recorded an impairment of $1.0 million related to such equipment. There was no impairment of long-lived assets for fiscal years 2024 and 2023.

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 revenue at a point in time when its performance obligation has been satisfied and control of the product is transferred 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. Sales to most distributors are made under terms allowing certain price adjustments of the Company’s products held in their inventory or upon sale to their end customers. Revenue from sales to distributors is recognized upon the transfer of control to the distributor. In the ordinary course of business, our distributors may need to sell our products to end customers at prices below the standard distribution price in order to remain competitive and secure sales. After the distributors sell the Company’s products to their end customers, the distributors submit a “ship-and-debit” price adjustment claim to the Company to adjust the distributor’s cost from the standard price to the pre-approved lower price. After the Company verifies that the claim was pre-approved, a credit memo is issued to the distributors for the ship-and-debit claim. In determining the transaction price, the Company considers ship-and-debit price adjustments to be variable consideration. The Company estimates the variable consideration of the allowance for price adjustments at the time revenue is recognized. The Company also allows stock rotation

75

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, expected sales volumes and individual distributor agreements. 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. The license and development fee required significant integration to create a combined output to the customer and was determined to be one performance obligation and was recognized over the 24 months when the Company performed the engineering and development services. The Company used the input method to measure progress and recognize revenue, based on the effort expended relative to the estimated total effort to satisfy the performance obligation. During the fiscal years ended June 30, 2025 and 2024, the Company recorded $13.8 million and $21.2 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. As of June 30, 2025, all revenue has been recognized and all consideration has been received associated with the license agreement.

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 costs to fulfill warranty obligation. The Company monitors its 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.

76

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 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. 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. 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. 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.

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

77

Advertising expenditures are expensed as incurred. Advertising expense was $0.5 million, $0.6 million and $0.5 million in the fiscal years ended June 30, 2025, 2024, and 2023, 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

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. The Company adopted the guidance during the three months ended June 30, 2025 and the adoption did not have a significant impact on the consolidated financial statements.

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 did not early adopt ASU 2023-09 and will apply these additional income tax disclosures in its June 2026 fiscal year.

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 annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of the ASU on its consolidated financial statements.

2. 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%.

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 $80 million based on the currency exchange rate as of January 26, 2022) (the “Investment”). Following the closing of the Investment, the percentage of outstanding JV equity interest beneficially owned by the Company was reduced to 42.2%.

78

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%.

On December 30, 2024, the JV Company signed an investment agreement with an investor, pursuant to which the third-party investor agreed to invest RMB 500 million (or $68.5 million based on the currency exchange rate between RMB and U.S. Dollar on December 31, 2024) in the JV Company in exchange for a 7.09% interest. This transaction closed on January 15, 2025, at which time, the percentage of outstanding JV Company’s equity interest owned by the Company was reduced to approximately 39.2%. We recorded a gain of $0.5 million on the change of equity interest in the JV Company, which was included in the equity method investment loss line in the consolidated statements of operations. The funding of the investment was agreed to be made in three installments. The JV Company received the first installment of RMB 40 million (or $5.5 million) on December 31, 2024. However, the JV Company has not received the remaining two installments as of the filing date.

In the fourth quarter of fiscal year 2025, the Company began negotiations with a third-party strategic investor to sell a portion of its outstanding equity interest in the JV Company. On July 14, 2025, the Company entered into an equity transfer agreement with the investor to sell approximately 20.3% of outstanding equity interest in the JV Company for an aggregate cash consideration of approximately $150 million to be paid in four installments, subject to satisfaction of certain conditions.

The Company identified the negotiations of the equity transfer agreement throughout the fourth quarter of fiscal year 2025 as an impairment indicator and performed a quantitative impairment test as of June 30, 2025. Based on the implied valuation of the JV Company per the transaction price in the equity transfer agreement, the fair value of the equity method investment was determined to be lower than its carrying value, and a $76.8 million other-than-temporary impairment of the equity method investment was recognized as of June 30, 2025. The impairment loss is recorded within Equity method investment loss in the consolidated statement of operations for the year-ended June 30, 2025.

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, 2025, 2024 and 2023, the Company recorded $77.8 million including the impairment loss, $4.8 million and $1.4 million of equity method investment loss, respectively, using lag reporting. As of June 30, 2025, the percentage of outstanding JV equity interest beneficially owned by the Company was 39.2%. The difference between the investment’s carrying value on June 30, 2025 of $279.1 million and the underlying equity in net assets of approximately $107.1 million as of March 31, 2025 relates primarily to equity method goodwill.

4. Net Income (Loss) Per Common Share

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, employee share purchase plan shares and vesting of restricted stock units using the treasury stock method. 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.

5. Concentration of Credit Risk and Significant Customers

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

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

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,

7. Bank Borrowing

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. As of June 30, 2025, there was no outstanding balance for this loan.

Debt financing

86

In September 2021, Jireh Semiconductor Incorporated (“Jireh”), one of the Company's 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 has a 5 years term, after which 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, until the final installation and acceptance of the equipment. 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 which had a carrying amount of $12.1 million as of June 30, 2025. As of June 30, 2025, the outstanding balance of this debt financing was $6.5 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 term of 5.5 years and matures on February 16, 2027. Jireh is required to make consecutive quarterly payments of principal and interest. The loan accrues interest based on the 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.

8. Leases

The Company evaluates contracts for lease accounting at contract inception and assesses lease classification at the lease commencement date. Operating leases are included in operating lease right-of-use (“ROU”) assets, operating lease liabilities and operating lease liabilities - long-term on the Company's 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 lease 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.

9. 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, 2025.

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 was no availability under this repurchase program, which was terminated. Prior to September 2017, the board of directors authorized two share purchase programs, which were terminated.

During fiscal years 2025 and 2024, the Company did not repurchase any shares pursuant to the repurchase program. 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.

As of June 30, 2025, 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, 214,809 shares with a weighted average repurchase price of $9.58 per share, were reissued at an average price of $3.89 per share for option exercises and vested restricted stock units.

10. 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 from 2021 to 2024, the shares reserved for issuance under the 2018 Plan was approved to increase by a total of 2,544,000 shares, to 4,609,000 shares. As of June 30, 2025, 541,000 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 total fair value of TRSUs vested during the years ended June 30, 2025, 2024 and 2023 was $17.9 million, $15.6 million and $13.0 million, respectively. The following table summarizes the Company’s TRSU activities:
