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 2,700 products, and has grown with the introduction of over 100 new products in the fiscal year ended June 30, 2024, and over 60 and 130 new products in the fiscal years ended June 30, 2023 and 2022, 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 930 patents and 52 patent applications in the United States as of June 30, 2024. We also have a total of 1,025 foreign patents, which primarily were based on our research and development efforts through June 30, 2024. 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, flat panel TVs, home appliances, power tools, smart phones, battery packs, consumer and industrial motor controls and power supplies for TVs, computers, servers and telecommunications equipment. During fiscal year 2024, we accelerated the development of new technology platforms which allowed us to introduce 36 medium and high voltage MOSFET products, targeting primarily the industrial markets and computing marketing, as well as 17 low voltage MOSFET products primarily for the computing market. In addition, we introduced 37 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.

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

On December 24, 2021, we 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 for 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.

509 million (or approximately USD 80 million based on the currency exchange rate as of January 26, 2022) (the “Investment”). Following the closing of the January 26, 2022 Investment, the percentage of outstanding JV equity interest beneficially owned by the Company was reduced to 42.2% at June 30, 2022.

In February 2024, the JV Company repurchased certain shares that were previously issued to employees under the employee equity incentive plan, which increased the Company’s percentage of equity ownership in the JV Company by 0.54%. As of June 30, 2024, the percentage of outstanding JV equity interest beneficially owned by the Company was 42.8%.

We reduced our ownership of the JV Company to below 50% to increase the flexibility of the JV Company to raise capital to fund its future expansion. The JV Company is also contemplating an eventual listing on the Science and Technology Innovation Board, or STAR Market, of the Shanghai Stock Exchange. The reduction of our ownership assists the JV Company in meeting certain regulatory listing requirements. A potential STAR Market listing may take several years to consummate and there is no guarantee that such listing by the JV Company will be successful or will be completed in a timely manner, or at all. In addition, the JV Company will continue to provide us with significant level of foundry capacity to enable us to develop and manufacture our products. On July 12, 2022, the current shareholders of the JV Company entered into a shareholders contract, pursuant to which the JV Company committed to provide us with a monthly wafer production capacity until December 2023, and additional commitment to provide wafer capacity after December 2023 if the JV Company’s production capacity reaches certain specified level.

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.

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 the JV Company to provide foundry capacity to manufacture our products, therefore it is critical that we maintain continuous access to such capacity, which may not be available at sufficient level or at a pricing terms favorable to us because of lack of control over the JV Company’s operation. We continue to maintain a business relationship with the JV Company to ensure uninterrupted supply of manufacturing capacity. Because we continue to rely on the JV Company to provide us with manufacturing capacity, if the JV Company take actions or make decisions that prevents 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. Both factors, timeliness of product introductions and conformance to customers' requirements, are equally important in securing design wins

with our customers. As we accelerate the development of new technology platforms, we expect to increase the pace at which we introduce new products and seek and acquire design wins. If we were to fail to introduce new products on a timely basis that meet customers’ specifications and performance requirements, particularly those products with major OEM customers, and continue to expand our serviceable markets, then we would lose market share and our financial performance would be adversely affected.

Distributor ordering patterns, customer demand and seasonality: Our distributors place purchase orders with us based on their forecasts of end customer demand, and this demand may vary significantly depending on the sales outlook and market and economic conditions of end customers. Because these forecasts may not be accurate, channel inventory held at our distributors may fluctuate significantly, which in turn may prompt distributors to make significant adjustments to their purchase orders placed with us. As a result, our revenue and operating results may fluctuate significantly from quarter to quarter. In addition, because our products are used in consumer electronics products, our revenue is subject to seasonality. Our sales seasonality is affected by numerous factors, including global and regional economic conditions as well as the PC market conditions, revenue generated from new products, changes in distributor ordering patterns in response to channel inventory adjustments and end customer demand for our products and fluctuations in consumer purchase patterns prior to major holiday seasons. In recent periods, broad fluctuations in the semiconductor markets and the global and regional economic conditions, in particular the 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 (“ODMs”) or original equipment manufacturers (“OEMs”), we may elect to grant special pricing that is below the prices at which we sold our products to the distributors. In 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 to provide 24-months of engineering and development services for a total fee of $45.0 million. We received payments of such fees in the amount of $18.0 million, $6.8 million and $9.0 million in March 2023, July 2023 and February 2024, respectively, with the remaining amount to be paid upon the achievement of specified engineering services and product milestones. The license and development fee is determined to be one performance obligation and is recognized over the 24 months during which we perform the engineering and development services. We use the input method to measure progression of the transfer of services. During the fiscal years ended June 30, 2024 and 2023, we recorded $21.2 million and $9.9 million of license and development revenue, respectively. We also entered 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.

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

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

Income tax expense

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

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

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

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

The Company is not currently subject to the Base Erosion and Anti-Abuse (BEAT) tax, which is a tax imposed on certain entities who make payments to their non U.S. affiliates, where such payments reduce the U.S. tax base. The BEAT tax is imposed at a rate of 10% on Adjusted Taxable Income, excluding certain payments to foreign related entities. It is an

incremental tax over and above the corporate income tax and is recorded as a period cost. It is possible that this tax could be applicable in future periods, which would cause an increase to the effective tax rate and cash taxes.

“The Chip and Science Act of 2022”, Enacted August 2, 2022

In August 2022 the U.S. enacted the Chip and Science Act of 2022 (the Chips Act).The Chips Act provides incentives to semiconductor chip manufacturers in the United States, including providing manufacturing investment credits of 25% for investments in semiconductor manufacturing property placed in service after December 31, 2022, for which construction begins before January 1, 2027.Property investments qualify for the 25% credit if, among other requirements, the property is integral to the operation of an advanced manufacturing facility, defined as having a primary purpose of manufacturing semiconductors or semiconductor manufacturing equipment.Currently, we are evaluating the impact of the Chips Act to us.

“The Inflation Reduction Act”, Enacted August 16, 2022

In August 2022 the United States enacted tax legislation through the Inflation Reduction Act (IRA).The IRA introduces a 15% corporate alternative minimum tax (CAMT) for corporations whose average annual adjusted financial statement income (AFSI) for any consecutive three-tax-year period preceding the applicable tax year exceeds $1 billion.The CAMT is effective for tax years beginning after 31 December 2022.The CAMT is currently not applicable to the Company.

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 is not in a position to determine whether the annual revenues may meet and/or cross the 750 million Euro threshold for at least two of the four fiscal years immediately preceding the fiscal year when CIT may apply. 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.

Equity method investment income/loss from equity investee

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 such affiliate 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 or tested for impairment. Instead the total equity method investment balance, including equity method goodwill, is tested for impairment. We review for impairment whenever factors indicate that the carrying amount of the investment might not be recoverable. In such a case, the decrease in value is recognized in the period the impairment occurs in the Consolidated Statement of Operations.

Operating results

The following tables set forth our results of operations and as a percentage of revenue for the fiscal years ended June 30, 2024, 2023 and 2022. Our historical results of operations are not necessarily indicative of the results for any future period.

Fiscal 2024 vs 2023

Total revenue was $657.3 million for fiscal year 2024, a decrease of $34.0 million, or 4.9%, as compared to $691.3 million for fiscal year 2023. The decrease was primarily due to a decrease of $32.6 million and $12.8 million in sales of power discrete products and power IC products, respectively. The decrease in power discrete and power IC product sales was primarily due to a 17.3% decrease in average selling price as compared to last fiscal year due to a shift in product mix, offset by a 12.3% increase in unit shipments. The decrease in revenues was primarily driven by the decreased sales in the consumer markets, particularly in gaming products, offset by the increase in the computing market, particularly in notebook and motherboard products. The increase in revenue from packaging and testing services and other for the fiscal year 2024 as compared to last fiscal year was primarily due to increased demand. The increase in license and development services for the fiscal year 2024 was related to the license agreement with a customer to license our proprietary SiC technology and to provide 24-months of engineering and development services in February 2023.

Fiscal 2023 vs 2022

Total revenue was $691.3 million for fiscal year 2023, a decrease of $86.2 million, or 11.1%, as compared to $777.6 million for fiscal year 2022. The decrease was primarily due to a decrease of $86.3 million and $2.3 million in sales of power discrete products and power IC products, respectively. The decrease in power discrete and power IC product sales was primarily due to a 30.1% decrease in unit shipments, offset by a 26.9% increase in average selling price as compared to last fiscal year due to a shift in product mix. The decrease in revenues was primarily driven by the significant decrease in the computing market, reflecting weaker demand for computers and inventory correction by our customers, in response to the industry-wide downturn in the semiconductor industry, partially offset by increased sales in the consumer markets, particularly in gaming products. The decrease in revenue from packaging and testing services for the fiscal year 2023 as compared to last

fiscal year was primarily due to decreased demand. The increase in license and development services for the fiscal year 2023 was related to the license agreement with a customer to license our proprietary SiC technology and to provide 24-months of engineering and development services in February 2023.

Cost of goods sold was $485.4 million for fiscal year 2024, a decrease of $6.4 million, or 1.3%, as compared to $491.8 million for fiscal year 2023. The decrease was primarily due to 4.9% decrease in revenue. Gross margin decreased by 2.7 percentage points to 26.2% for the fiscal year 2024, as compared to 28.9% for the fiscal year 2023. The decrease in gross margin was primarily due to higher material costs and less favorable product mix during the fiscal year ended June 30, 2024. 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.

Fiscal 2023 vs 2022

Cost of goods sold was $491.8 million for fiscal year 2023, a decrease of $17.2 million, or 3.4%, as compared to $509.0 million for fiscal year 2022. The decrease was primarily due to 11.1% decrease in revenue. Gross margin decreased by 5.6 percentage points to 28.9% for the fiscal year 2023, as compared to 34.5% for the fiscal year 2022. The decrease in gross margin was primarily due to higher material costs and lower unit shipments during the fiscal year ended June 30, 2023.

Research and development expenses were $89.9 million for fiscal year 2024, an increase of $1.8 million, or 2.0%, as compared to $88.1 million for fiscal year 2023. The increase was primarily attributable to a $3.0 million increase in employee compensation and benefit expense mainly due to increased headcount and higher business and medical insurance expenses as well as higher bonus expense and vacation expense, a $0.8 million increase in depreciation expenses, and a $2.1 million increase in allocation expenses, partially offset by a $4.2 million decrease in share-based compensation expense as a result of a cancellation of certain performance-based restricted stock units and an assessment of zero attainment for certain market-based restricted stock units. 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.

Fiscal 2023 vs 2022

Research and development expenses were $88.1 million for fiscal year 2023, an increase of $16.9 million, or 23.7%, as compared to $71.3 million for fiscal year 2022. The increase was primarily attributable to a $3.9 million increase in employee compensation and benefit expense mainly due to increased headcount and higher medical insurance expenses, partially offset by lower vacation accrual and lower bonus accrual, a $2.4 million increase in share-based compensation expense due to an

increase in stock awards granted, a $3.6 million increase in depreciation expenses, a $2.2 million increase in allocation expenses, and a $4.8 million increase in product prototyping engineering expense as a result of increased engineering activities.

Income tax expense decreased by $2.3 million, or 38.5% in fiscal year 2024 as compared to fiscal year 2023. The income tax expense of $3.6 million for the year ended June 30, 2024 included a $0.2 million discrete tax expense, and the income tax expense of $5.9 million for the year ended June 30, 2023 included a $0.1 million discrete tax expense. Excluding the discrete income tax items, the effective tax rate for the years ended June 30, 2024 and 2023 was (130.6)% and 29.4%, respectively. The changes in the tax expense and effective tax rate between the periods resulted primarily from the Company reporting pretax book loss of $2.6 million for the year ended June 30, 2024 as compared to a pretax book income of $19.7 million for year ended June 30, 2023 as well as changes in the mix of earnings in various geographic jurisdictions between the current year and the same period of last year.

Fiscal 2023 vs 2022

Income tax expense for fiscal years 2023 and 2022 was $5.9 million and $39.3 million, respectively. Income tax expense decreased by $33.3 million, or 84.9% in fiscal year 2023 as compared to fiscal year 2022. The income tax expense of $5.9 million for the year ended June 30, 2023 included a $0.1 million discrete tax expense, and the income tax expense of $39.3 million for the year ended June 30, 2022 included a $33.5 million discrete tax expense related to the Company’s $396.0 million of income from the sale of equity interest in a joint venture and the related deconsolidation gain as the Company changed from the consolidation method of accounting to the equity method of accounting. In addition, for the year ended June 30, 2022 we recorded a tax benefit of $0.4 million from other discrete income tax items. Excluding the discrete income tax items, the effective tax rate for the years ended June 30, 2023 and 2022 was 29.4% and 6.3%, respectively. The changes in the tax expense and effective tax rate between the periods resulted primarily from the Company reporting pretax book income of $19.7 million for the year ended June 30, 2023 as compared to a pretax book income of $495.0 million ($99.0 million of pretax book income plus the $396.0 million of income from the sale of equity interest in a joint venture and the related deconsolidation gain) for the year ended June 30, 2022 as well as changes in the mix of earnings in various geographic jurisdictions between the current year and the same period of last year.

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 March 2024, Bank of Communications Limited in China provided a line of credit facility to one of the Company's subsidiaries in China. The purpose of the credit facility is to provide working capital borrowings. The Company could borrow up to approximately RMB 140 million or $19.3 million based on currency exchange rate between RMB and U.S. Dollar on June 30, 2024 with a maturity date of March 15, 2025. As of June 30, 2024, there was no outstanding balance for this loan.

In December 2023, Industrial and Commercial Bank of China provided a line of credit facility to one of the Company's subsidiaries in China. The purpose of the credit facility was to provide working capital borrowings. The Company could borrow up to approximately RMB 72.0 million, or $9.9 million based on currency exchange rate between RMB and U.S. Dollar on June 30, 2024, with a maturity date of December 31, 2024. As of June 30, 2024, there was no outstanding balance for this loan.

In September 2023, China Construction Bank provided a line of credit facility to one of the Company's subsidiaries in China. The purpose of the credit facility is to provide working capital borrowings. The Company could borrow up to approximately RMB 50 million or $6.9 million based on currency exchange rate between RMB and U.S. Dollar on June 30, 2024 with a maturity date of September 8, 2025. As of June 30, 2024, there was no outstanding balance for this loan.

On February 6, 2023, we entered into a license and engineering service agreement with a leading power semiconductor automotive supplier related to our Silicon Carbide (SiC) MOSFET and diode technology. Pursuant to the agreement, we license and provide 24-months of engineering support for our proprietary SiC technology to the supplier for a total fee of $45.0 million. We received payments of such fees in the amount of $18.0 million, $6.8 million and 9.0 million in March 2023, July 2023 and February 2024, respectively, and the remaining amount to be paid upon our achievements of specified business and product milestones. In addition, we entered an accompanying supply agreement with the supplier to provide it with limited wafer supply.

In September 2021, Jireh Semiconductor Incorporated (“Jireh”), one of the wholly-owned subsidiaries, entered into a financing arrangement agreement with a company (“Lender”) for the lease and purchase of a machinery equipment manufactured by a supplier. This agreement 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 $13.6 million as of June 30, 2024. As of June 30, 2024, the outstanding balance of this debt financing was $9.2 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 adjusted LIBOR plus the applicable margin based on the outstanding balance of the loan. This agreement contains customary restrictive covenants and includes certain financial covenants that 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, 2024, Jireh was in compliance with these covenants and the outstanding balance of this loan was $29.2 million.

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. The Borrower was in compliance with these covenants as of June 30, 2024. As of June 30, 2024, there was no outstanding balance of this factoring agreement.

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 Renminbi 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 Renminbi to purchase foreign exchange currency for settlement of such “current account” transactions without the pre-approval from China's State Administration of Foreign Exchange (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 into the statutory reserve fund to fund the 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 Renminbi 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" 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, 2024 and 2023, such restricted portion amounted to approximately $93.5 million and $93.2 million, or 10.5% and 10.5%, of our total consolidated net assets attributable to the Company, respectively.

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

Cash, cash equivalents and restricted cash

As of June 30, 2024 and 2023, we had $175.5 million and $195.6 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 $175.5 million and $195.6 million cash and cash equivalents, $55.0 million and $108.2 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:

Commitments

See Note 15 of the Notes to the consolidated financial statements contained in this Annual Report on Form 10-K for a description of commitments.

Off-Balance Sheet Arrangements

As of June 30, 2024, we had no off-balance sheet arrangements.

Critical Accounting Policies and Estimates

The preparation of our consolidated financial statements requires us 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, our consolidated financial statements will be affected. On an ongoing basis, we evaluate the estimates, judgments and assumptions including those related to stock rotation returns, price adjustments, allowance for doubtful accounts, valuation of inventories, warranty accrual, income taxes, leases, equity method investment, share-based compensation, recoverability of and useful lives for property, plant and equipment and intangible assets.

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 revenue at a point in time when product is shipped to the customer, net of estimated stock rotation returns and price adjustments 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 our products globally to various end customers. Our revenue is net of the effect of the variable consideration relating to estimated stock rotation returns and price adjustments that we expect to provide to certain distributors. Stock rotation returns are governed by contract and are limited to a specified percentage of the monetary value of the products purchased by distributors during a specified period. We estimate provision for stock rotation returns based on historical returns and individual distributor agreements. We also provide special pricing to certain distributors primarily based on volume, to encourage resale of our products. We estimate the expected price adjustments at the time the revenue is recognized based on distributor inventory levels, forecasted future distributor selling prices, distributor margins and demand for our products. If actual stock rotation returns or price adjustments differ from our estimates, adjustments may be recorded in the period when such actual information is known. Allowance for price adjustments is recorded against accounts receivable and provision for stock rotation is recorded in accrued liabilities on the consolidated balance sheets.

Our performance obligations relate to contracts with a duration of less than one year. We elected to apply the practical expedient provided in ASC 606, “Revenue from Contracts with Customers”. Therefore, we are 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.

We recognize 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, we recognize commissions as expense when incurred, as the amortization period of the commission asset we 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 Revenue Recognition

In February 2023, we entered into a license agreement with a customer to license our proprietary SiC technology and to provide 24-months of engineering and development services for a total fee of $45.0 million, consisting of an upfront fee of $18.0 million, $6.8 million and $9.0 million paid to us in March 2023, July 2023 and February 2024, respectively, with the remaining amount to be paid upon the achievement of specified engineering services and product milestones. The license and development fee is determined to be one performance obligation and is recognized over the 24 months when we perform the engineering and development services. We use the input method to measure progression, representing a faithful depiction of the transfer of services. During the fiscal years ended June 30, 2024 and 2023, we recorded $21.2 million and $9.9 million of license and development revenue. The amount of contract liability is recorded as deferred revenue on the consolidated balance sheets. In addition, we also entered an accompanying supply agreement to provide limited wafer supply to the customer.

Equity method investment

We use the equity method of accounting when we have the ability to exercise significant influence, but not control, as determined in accordance with general accepted accounting principles, over the operating and financial policies of the investee. Effective December 2, 2021, we reduced our equity interest in the JV Company, which resulted in deconsolidation of our investment in the JV Company. As a result, beginning December 2, 2021, we record our investment under equity method of accounting. Due to difficulties in obtaining accurate financial information from the JV Company in a timely manner, we record our share of earnings or losses of such affiliate on a one quarter lag. Therefore, our share of losses of the

JV Company for the period from December 2, 2021 to March 31, 2022 was recorded in our Consolidated Statement of Operations for the fiscal year ended June 30, 2022. And our share of losses of the JV Company for the periods of April 1, 2022 to March 31, 2023 and April 1 2023 to March 31, 2024 were recorded in our Consolidated Statement of Operations for the fiscal years ended June 30, 2023 and 2024. We recognize and disclose intervening events at the JV Company in the lag period that could materially affect our consolidated financial statements.

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 and investee. Basis differences represent differences between the cost of the investment and the underlying equity in net assets of the investment and are generally amortized over the lives of the related assets that gave rise to them. Equity method goodwill is not amortized or tested for impairment; instead the equity method investment is tested for impairment. We review for impairment whenever factors indicate that the carrying amount of the investment might not be recoverable. In such a case, the decrease in value is recognized in the period the impairment occurs in the Consolidated Statements of Operations.

Valuation of inventories

We carry inventories at the lower of cost (determined on a first-in, first-out basis) or net realizable value. Cost primarily consists of semiconductor wafers and raw materials, labor, depreciation expenses and other manufacturing expenses and overhead, and packaging and testing fees paid to third parties if subcontractors are used. Valuation of inventories is based on our periodic review of inventory quantities on hand as compared with our sales forecasts, historical usage, aging of inventories, production yield levels and current product selling prices. If actual market conditions are less favorable than those forecasted by us, additional future inventory write-downs may be required that could adversely affect our operating results. Adjustments to inventory, once established are not reversed until the related inventory has been sold or scrapped. If actual market conditions are more favorable than expected and the products that have previously been written down are sold, our gross margin would be favorably impacted.

Accounting for income taxes

We are subject to income taxes in a number of jurisdictions.We must make certain estimates and judgments in determining income tax expense for financial statement purposes.These estimates and judgments occur in the calculation of tax credits, benefits and deductions, and in the calculation of certain tax assets and liabilities which arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes, as well as interest and penalties related to uncertain tax positions.There are many transactions and calculations for which the ultimate tax determination is uncertain during the ordinary course of business.We establish 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.As a result, significant changes to these estimates may result in an increase or decrease to our tax provision in a subsequent period.

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 foreign 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.We consider 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.We consider evidence such as our past operating results, the existence of cumulative losses in recent years and our forecast of future taxable income.We will maintain a partial valuation allowance equal to the state research and development credit carryforwards until sufficient positive evidence exists to support reversal of the valuation allowance.

We intend to reinvest the undistributed earnings of its foreign subsidiaries indefinitely, except for Alpha and Omega Semiconductor (Cayman) Ltd. and AOS International LP. As of June 30, 2024, the cumulative earnings of Alpha and Omega Semiconductor (Cayman) and AOS International LP totaled $46.2 million, and there was no deferred tax liability recorded as there is no income nor withholding tax amongst the applicable jurisdictions. As of June 30, 2024, the cumulative amount of undistributed earnings of its foreign entities considered permanently reinvested is $414.6 million. Should the Company decide to remit this income to its Bermuda parent company in a future period, its provision for income taxes may increase materially in that period. The determination of the unrecognized deferred tax liability on these earnings is not practicable due to the complexity and variety of assumptions necessary to estimate the tax. As of June 30, 2024, the Company has recorded a deferred tax liability of $26.3 million for the basis difference related to our investment in the JV Company.

The Financial Accounting Standards Board ("FASB") has 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.The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax law and regulations in a multitude of jurisdictions.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.

Our 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.We are subject to the continuous examination of our income tax returns by the Internal Revenue Service and other tax authorities.We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes.There can be no assurance that the outcomes from these continuous examinations will not have an adverse effect on our operating results and financial condition.To the extent that the final tax outcome of these matters is different than 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

We maintain an equity-settled, share-based compensation plan to grant restricted share units and stock options. We recognize 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 our common share on the date of grant. For restricted stock awards subject to market conditions, the fair value of each restricted stock award is estimated at the date of grant using the Monte-Carlo pricing model. The fair value of stock options is estimated on the date of grant using the Black-Scholes option valuation model. Share-based compensation expense is recognized on the accelerated attribution basis over the requisite service period of the award, which generally equals the vesting period.The Employee Share Purchase Plan (the “ESPP”) is accounted for at fair value on the date of grant using the Black-Scholes option valuation model. Share-based compensation expense is significant to the consolidated financial statements and is calculated using our best estimates, which involve inherent uncertainties and the application of management's judgment. The Black-Scholes option valuation model requires the input of subjective assumptions, including the expected term and stock price volatility. In addition, judgment is also required in estimating the number of stock-based awards that are expected to be forfeited. Forfeitures are estimated based on historical experience at the time of grant. Changes in estimated forfeitures are recognized in the period of change and impact the amount of stock compensation expenses to be recognized in future periods, which could be material if actual results differ significantly from estimates.

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 (“RMB”) 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. dollar 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) and noncontrolling interest 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, 2024, we had $38.4 million outstanding under our loan and $3.2 million outstanding under our financing leases, which were subject to fluctuations in interest rates. For the year ended June 30, 2024, a hypothetical 10% increase in the interest rate could result in $0.2 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, 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, would decrease or increase our current year's net earnings by $0.6 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, 2024, 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, 2024.

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, 2024.

The effectiveness of the Company’s internal control over financial reporting as of June 30, 2024 has been audited by Baker Tilly US, LLP, an independent registered public accounting firm, as stated in their report, included on page 67.

Remediation of Previously Disclosed Material Weakness

As previously disclosed in Item 9A of our Annual Report on Form 10-K for the fiscal year ended June 30, 2023 (the “prior year Form 10-K”), and in subsequent quarterly reports, we did not (i) design and maintain effective information technology general controls in the areas of user access, and segregation of duties for one of the information technology systems that supports the Company’s financial reporting over inventory (work in process and finished goods) in costing; and (ii) identify and test controls to ensure the reliability of the costing of inventory (work in process and finished goods).

We executed the following remediation measures, including testing and evaluation of the newly designed and enhanced controls:

•Designed and implemented controls to further improve information technology general controls in the areas of user access and segregation of duties (work in process and finished goods); and

•Designed and implemented controls over inventory costing (work in process and finished goods)

Based upon the above, we have determined that these control activities are appropriately designed and implemented, and operating effectively for a sufficient period of time to conclude that the previously identified material weakness has been remediated as of June 30, 2024.

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. Except for the remediation efforts implemented in connection with the material weakness discussed above, there were no changes during the quarter ended June 30, 2024.

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 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 stockholders and the Board of Directors of Alpha and Omega Semiconductor Limited:

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Alpha and Omega Semiconductor Limited (the "Company") as of June 30, 2024 and 2023, the related consolidated statements of operations, comprehensive income (loss), equity, and cash flows, for each of the two years in the period ended June 30, 2024, and the related notes and schedule (collectively referred to as the "consolidated financial statements"). We also have audited the Company’s internal control over financial reporting as of June 30, 2024, 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 consolidated financial statements present fairly, in all material respects, the financial position of the Company as of June 30, 2024 and 2023, and the results of its operations and its cash flows for each of the two years in the period ended June 30, 2024 and 2023, in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of June 30, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Annual Report on Internal Control over Financial Reporting included in Item 9A of this Annual Report on Form 10-K. Our responsibility is to express an opinion on the Company's consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("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 audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the consolidated 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 consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

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.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated 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 consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Excess and Obsolete Inventory Reserve

As described in Note 1 of the consolidated financial statements, the Company assesses the valuation of its inventory on a periodic basis and provides an allowance based on several factors including inventory quantities on hand as compared with its sales forecasts, historical usage, aging of inventories, production yield levels and current product selling prices.

We identified the provision for excess and obsolete inventory as a critical audit matter because the determination of excess and obsolete inventory reserves is judgmental and considers several factors that are affected by market and economic conditions, such as company forecasts, dynamic pricing environments, and industry supply and demand.

How the critical audit matter was addressed in the audit

Our audit procedures related to management’s estimates used in the valuation of inventory included the following, among others:

•We evaluated and tested the design and operating effectiveness of the Company's internal controls over the valuation of inventory, including the calculation of lower of cost or net realizable value reserves, and the determination of demand forecasts and related application against on hand inventory.

•We reviewed the reasonableness of the Company’s methodology for estimating the valuation of inventories by evaluating factors including excess units on hand based on ending inventory quantities compared to forecasted shipment quantities.

•We tested the significant assumptions, including product demand forecasts, and the completeness and accuracy of the underlying data used in management's inventory valuation assessment.

•We evaluated management’s ability to accurately estimate forecasted demand by comparing estimates made in prior periods to the historical actual results for those same periods.

Revenue recognition – Variable consideration of the allowance for price adjustments

As described in Notes 1 and 6 of the consolidated financial statements, the Company provides special pricing to certain distributors, primarily based on volume, to encourage resale of the Company's products. The Company estimates the variable consideration of the allowance for price adjustments at the time revenue is recognized. The Company records a reduction of revenue and a corresponding allowance for price adjustments against accounts receivable on the consolidated balance sheets.

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 identified the variable consideration of the allowance for price adjustments as a critical audit matter because auditing management’s estimate of the allowance for price adjustments was complex, due to the significant assumptions used in estimating the variable consideration.

How the critical audit matter was addressed in the audit

Our audit procedures related to management’s estimate of the variable consideration of the allowance for price adjustments included the following, among others:

•We evaluated and tested the design and operating effectiveness of the Company's internal controls for estimating the variable consideration of the allowance for price adjustments, including testing controls over management’s review of the allowance calculation and the underlying assumptions used to develop the estimate.

•We confirmed the quantity of select distributor inventories.

•We tested revenues and allowance for price adjustments and agreed to supporting documents.

•We evaluated the reasonableness of management’s significant assumptions by comparing them to the forecasted distributor selling prices, as well as historical results of the company, including testing the completeness and accuracy of the underlying data.

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 and portable computers, graphic cards, flat panel TVs, home appliances, smart phones, battery packs, quick chargers, home appliances, consumer and industrial motor controls and power supplies for TVs, computers, servers and telecommunications equipment. The Company conducts its operations primarily in the United States of America (“USA”), Hong Kong, China, and South Korea.

Basis of Preparation

The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and a subsidiary in which it had a controlling interest until December 1, 2021. As of December 2, 2021, the Company ceased having control over this subsidiary. Therefore, the Company deconsolidated this subsidiary as of that date.Subsequently, the Company has accounted for it using the equity method of accounting.All intercompany account balances and transactions have been eliminated. The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

Joint Venture

On March 29, 2016, the Company entered into a joint venture contract (the “JV Agreement”) with two investment funds owned by the Municipality of Chongqing (the “Chongqing Funds”), pursuant to which the Company and the Chongqing Funds formed a joint venture, the JV Company, for the purpose of constructing and operating a power semiconductor packaging, testing and 12-inch wafer fabrication facility in the Liangjiang New Area of Chongqing, China (the “JV Transaction”). As of December 1, 2021, the Company owned 50.9%, and the Chongqing Funds owned 49.1%, of the equity interest in the JV Company. The Joint Venture was accounted under the provisions of the consolidation guidance since the Company had controlling financial interest until December 1, 2021. As of December 2, 2021, the Company ceased having control over the JV Company. Therefore, the Company deconsolidated the JV Company as of that date. Subsequently, the Company has accounted for its investment in the JV Company using the equity method of accounting. As of June 30, 2023, the percentage of outstanding JV equity interest beneficially owned by the Company was reduced to 42.2%. Such reduction reflects (i) the sale by the Company of approximately 2.1% of the outstanding JV equity interest which resulted in the deconsolidation of the JV Company, (ii) additional sale by the Company of approximately 1.1% of outstanding JV equity interest in December 2021, (iii) the adoption of an employee equity incentive plan and the issuance of additional equity interest equivalent to 3.99% of the JV Company to investors in exchange for cash in December 2021, and (iv) issuance of additional equity interest of JV to investors in January 2022. In February 2024, the JV Company repurchased certain shares that were previously issued to employees under the employee equity incentive plan, which increased the Company’s percentage of equity ownership in the JV Company by 0.54%. As of June 30, 2024, the percentage of outstanding JV equity interest beneficially owned by the Company was 42.8%.

Risks and Uncertainties

The Company is subject to certain risks and uncertainties. The Company believes changes in any of the following areas could have a material adverse effect on the Company's future financial position or results of operations or cash flows: the macroeconomic condition and cyclical nature of the semiconductor industry; the timing and success of new product development, including market receptiveness, operation of in-house manufacturing facilities, litigation or claims against the Company based on intellectual property, patent, product regulatory or other factors, competition from other products, general economic conditions, the inability to attract and retain qualified employees, lack of control of the JV Company and ultimately to sustain profitable operations, risks associated with doing business in China, and ability to diversify products and develop digital business; the general state of the U.S., China and world economies; the loss of any of its larger customers; restrictions on the Company’s ability to sell to foreign customers due to trade laws, regulations and requirements; disruptions of the supply chain of components needed for our products; inability to obtain additional financing; inability to meet certain debt covenants; fundamental changes in the technology underlying the Company’s products; successful and timely completion of product design efforts; and new product design introductions by competitors. Additional risks and uncertainties that the Company is unaware of, or that the Company currently believes are not material, may also become important factors that adversely affect its business.

The Company's revenue is limited by its ability to utilize wafer production and packaging and testing capacity from its in-house facilities and obtain adequate wafer supplies from third-party foundries. Currently the Company's main third-party foundry is Shanghai Hua Hong Grace Electronic Company Limited, or HHGrace, located in Shanghai, China. HHGrace has been manufacturing wafers for the Company since 2002. HHGrace manufactured approximately 3.8%, 9.6% and 10.3% of the wafers used in the Company's products for the fiscal years ended June 30, 2024, 2023 and 2022, respectively. Although the Company believes that its volume of production allows the Company to secure favorable pricing and priority in allocation of capacity in its third-party foundries, if the foundries' capacities are constrained due to market demands, HHGrace, together with other foundries from which the Company purchases wafers, may not be willing or able to satisfy all of the Company's manufacturing requirements on a timely basis and/or at favorable prices. In addition, manufacturing facilities' capacity affects the Company's gross margin because the Company has certain fixed costs associated with its Oregon Fab as well as in-house packaging and testing facilities. If the Company fails to utilize its manufacturing facilities' capacity at a desirable level, its financial condition and results of operations will be adversely affected.

Use of Estimates

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

Foreign Currency Transactions and Translation

Most of the Company's principal subsidiaries use U.S. dollars as their functional currency because their transactions are primarily conducted and settled in U.S. dollars. All of their revenues and a significant portion of their operating expenses are denominated in U.S. dollars. The functional currencies for the Company's in-house packaging and testing facilities in China are U.S. dollars, and a majority of their capital expenditures are denominated in U.S. dollars. Foreign currency transactions are translated into the functional currencies using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses, resulting from the settlement of such transactions and from the re-measurement of monetary assets and liabilities denominated in foreign currencies using exchange rates at balance sheet date and non-monetary assets and liabilities using historical exchange rates, are recognized in the consolidated statements of operations.

For the Company's subsidiaries which use the local currency as their functional currency, their results and financial position are translated into U.S. dollars using exchange rates at balance sheet dates for assets and liabilities and using average exchange rates for income and expenses items. The resulting translation differences are presented as a separate component of accumulated other comprehensive income (loss) in the consolidated statements of equity.

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents primarily consist of cash on hand and short-term bank deposits with original maturities of three months or less. Cash equivalents are highly liquid investments with stated maturities of three months or less as of the dates of purchase. The carrying amounts reported for cash and cash equivalents are considered to approximate fair values based upon their short maturities.

Cash and cash equivalents are maintained with reputable major financial institutions. If, due to current economic conditions or other factors, one or more of the financial institutions with which the Company maintains deposits fails, the Company's cash and cash equivalents may be at risk. Deposits with these banks may exceed the amount of insurance provided on such deposits; however, these deposits typically may be redeemed upon demand and, therefore, bear minimal risk.

The Company maintains restricted cash in connection with cash balances temporarily restricted for regular business operations. These balances have been excluded from the Company’s cash and cash equivalents balance and are classified as restricted cash in the Company’s consolidated balance sheets. As of June 30, 2024 and 2023, the amount of restricted cash was $0.4 million and $0.4 million, respectively.

Accounts Receivable, net

The allowance for expected credit loss is based on assessment of the expected collectability of accounts receivable from customers. The Company reviews the allowance by considering factors such as historical collection experience, credit quality, age of the accounts receivable balances and current economic conditions that may affect a customer's ability to pay. The

Company writes off a receivable and charges against its recorded allowance when it has exhausted its collection efforts without success.

Fair Value Measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy is based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, which are the following:

•Level 1 - Quoted prices in active markets for identical assets or liabilities.

•Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Fair Value of Financial Instruments

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

Inventories

The Company carries inventories at the lower of cost (determined on a first-in, first-out basis) or net realizable value. Cost includes semiconductor wafer and raw materials, labor, depreciation expenses and other manufacturing expenses and overhead, and packaging and testing fees paid to third parties if subcontractors are used. Valuation of inventories are based on the Company's periodic review of inventory quantities on hand as compared with its sales forecasts, historical usage, aging of inventories, production yield levels and current product selling prices. If actual market conditions are less favorable than those forecasted by management, additional future inventory write-downs may be required that could adversely affect the Company's operating results. Adjustments to inventory once established are not reversed until the related inventory has been sold or scrapped. If actual market conditions are more favorable than expected and the products that have previously been written down are sold, our gross margin would be favorably impacted.

Property, Plant and Equipment

Property, plant and equipment are stated at historical cost less accumulated depreciation. Historical cost includes expenditures that are directly attributable to the acquisition of the items and the costs incurred to make the assets ready for their intended use.

Depreciation is provided for on a straight-line basis over the estimated useful lives of the related assets as follows:

Building and building improvements 20 years

Manufacturing machinery and equipment 7 to 10 years

Equipment and tooling 3 to 5 years

Computer hardware and software 3 to 5 years

Office furniture and equipment 3 to 5 years

Leasehold improvements 2 to 15 years

Vehicle 5 years

Equipment and construction in progress represent equipment received but the necessary installation has not been fully performed or building construction and leasehold improvements have been started but not yet completed. Equipment and construction in progress are stated at cost and transferred to the respective asset class when fully completed and ready for their intended use.

Internal-use software development costs are capitalized to the extent that the costs are directly associated with the development of identifiable and unique software products controlled by the Company that will probably generate economic benefits beyond one year. Costs incurred during the application development stage are required to be capitalized. The application development stage is characterized by software design and configuration activities, coding, testing and installation. Training costs and maintenance are expensed as incurred, while upgrades and enhancements are capitalized if it is probable that such expenditures will result in additional functionality. Costs include employee costs incurred and fees paid to outside consultants for the software development and implementation. Internally developed software is amortized over its estimated useful life of three 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, 2024, the Company reduced property, plant and equipment by $1.0 million. During the fiscal year ended June 30, 2023, the Company reduced property, plant and equipment by $0.6 million and operating expenses by $0.1 million. During the fiscal year ended June 30, 2022, the Company reduced interest expense by $0.9 million, property, plant and equipment by $1.4 million, and operating expenses by $0.2 million.

Long-lived Assets

The Company reviews all long-lived assets whenever events or changes in circumstance indicate that these assets may not be recoverable. When evaluating long-lived assets, if the Company concludes that the estimated undiscounted cash flows attributable to the assets are less than their carrying value, the Company recognizes an impairment loss based on the excess of the carrying amount of the assets over their respective fair values, which could adversely affect its results of operations.

There was no impairment of long-lived assets for fiscal years 2024, 2023 and 2022.

Revenue Recognition

The Company determines revenue recognition through the following steps: (1) identification of the contract with a customer; (2) identification of the performance obligations in the contract; (3) determination of the transaction price; (4) allocation of the transaction price to the performance obligations in the contract; and (5) recognition of revenue when, or as, a performance obligation is satisfied. The Company recognizes product revenue at a point in time when product is shipped to the customer, as determined by the agreed upon shipping terms, net of estimated stock rotation returns and price adjustments that it expects to provide to certain distributors. The Company presents revenue net of sales taxes and any similar assessments. Our standard payment terms range from 30 to 60 days.

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

The Company's performance obligations relate to contracts with a duration of less than one year. The Company elected to apply the practical expedient provided in ASC 606, “Revenue from Contracts with Customers”. Therefore, the Company is not

required to disclose the aggregate amount of transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied at the end of the reporting period.

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

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

License and Development Services Revenue Recognition

In February 2023, the Company entered into a license agreement with a customer to license the Company’s proprietary SiC technology and to provide 24-months of engineering and development services for a total fee of $45.0 million, consisting of an upfront fee of $18.0 million, $6.8 million and $9.0 million paid to the Company in March 2023, July 2023 and February 2024, respectively, with the remaining amount to be paid upon the achievement of specified engineering services and product milestones. The license and development fee is determined to be one performance obligation and is recognized over the 24 months when the Company performs the engineering and development services. The Company uses the input method to measure progression, representing a faithful depiction of the transfer of services. During the fiscal years ended June 30, 2024 and 2023, the Company recorded $21.2 million and $9.9 million of license and development revenue, respectively. The amount of contract liability is recorded as deferred revenue on the consolidated balance sheets. In addition, the Company also entered an accompanying supply agreement to provide limited wafer supply to the customer.

Leases

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

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The Company determines its incremental borrowing rate based on the information available at the lease commencement date. The operating lease ROU assets also include any lease payments made and exclude lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. Operating lease expense is generally recognized on a straight-line basis over the lease term. Variable lease payments are expensed as incurred and are not included within the operating lease ROU asset and lease liability calculation. The Company does not record leases on the consolidated balance sheet with a term of one year or less. The Company elected to combine its lease and non-lease components as a single lease component for all asset classes.

Product Warranty

The Company provides a standard one-year warranty for products from the date of purchase by the end customers. The Company accrues for estimated warranty costs at the time revenue is recognized. The Company's warranty obligation is determined by product failure rates, labor and material costs for replacing defective parts, related freight costs for failed parts and other quality assurance costs. The Company monitors its product returns for warranty claims and maintains warranty reserves based on historical experiences and anticipated warranty claims known at the time of estimation.

Shipping and Handling Costs

Shipping and handling costs are included in cost of goods sold.

Research and Development

Research and development costs are expensed as incurred.

Provision for Income Taxes

Income tax expense or benefit is based on income or loss before taxes.Deferred tax assets and liabilities are recognized principally for the expected tax consequences of temporary differences between the tax basis of assets and liabilities and their reported amounts.

The Company is subject to income taxes in a number of jurisdictions.Significant judgment is required in determining the worldwide provision for income taxes.There are many transactions and calculations for which the ultimate tax determination is uncertain during the ordinary course of business.The Company establishes accruals for certain tax contingencies based on estimates of whether additional taxes may be due.While the final tax outcome of these matters may differ from the amounts that were initially recorded, such differences will impact the income tax and deferred tax provisions in the period in which such determination is made.

Significant management judgment is also required in determining whether deferred tax assets will be realized in full or in part.When it is more likely than not that all or some portion of specific deferred tax assets such as net operating losses or research and experimentation tax credit carryforwards will not be realized, a valuation allowance must be established for the amount of the deferred tax assets that cannot be realized.The Company considers all available positive and negative evidence on a jurisdiction-by-jurisdiction basis when assessing whether it is more likely than not that deferred tax assets are recoverable.The Company considers evidence such as our past operating results, the existence of cumulative losses in recent years and our forecast of future taxable income.The Company has concluded that it should report a full valuation allowance on its state research and development (R&D) tax credit carryforwards as the Company annually generates more state R&D tax credits than it could use based on its forecasts.

The Financial Accounting Standards Board (FASB), issued guidance which clarifies the accounting for income taxes by prescribing a minimum probability threshold that a tax position must meet before a financial statement benefit is recognized.The minimum threshold is defined as a tax position that is more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any related appeals or litigation processes, based on the technical merits of the position.The tax benefit to be recognized is measured as the largest amount of benefit that is greater than fifty percent likely to be realized upon ultimate settlement.Although the guidance on the accounting for uncertainty in income taxes prescribes the use of a recognition and measurement model, the determination of whether an uncertain tax position has met those thresholds will continue to require significant judgment by management.If the ultimate resolution of tax uncertainties is different from what is currently estimated, a material impact on income tax expense could result.

The Company's provision for income taxes is subject to volatility and could be adversely impacted by changes in earnings or tax laws and regulations in various jurisdictions.The Company is subject to the continuous examination of our income tax returns by the Internal Revenue Service and other tax authorities.The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes.To the extent that the final tax outcome of these matters is different from the amounts recorded, such differences will impact the provision for income taxes in the period in which such determination is made.The provision for income taxes includes the impact of changes to reserves, as well as the related net interest and penalties.

Share-based Compensation Expense

The Company maintains an equity-settled, share-based compensation plan to grant restricted share units and stock options. The Company recognizes expense related to share-based compensation awards that are ultimately expected to vest based on estimated fair values on the date of grant. The fair value of restricted share units is based on the fair value of the Company's common share on the date of grant. For restricted stock awards subject to market conditions, the fair value of each restricted stock award is estimated at the date of grant using the Monte-Carlo pricing model. The fair value of stock options is estimated on the date of grant using the Black-Scholes option valuation model. Share-based compensation expense is recognized on the accelerated attribution basis over the requisite service period of the award, which generally equals the vesting period. The Black-Scholes option valuation model requires the input of subjective assumptions, including the expected term and stock price volatility. In addition, judgment is also required in estimating the number of stock-based awards that are expected to be forfeited. Forfeitures are estimated based on historical experience at the time of grant. Changes in estimated forfeitures are recognized in the period of change and impact the amount of stock compensation expenses to be recognized in future periods, which could be material if actual results differ significantly from estimates.

The Employee Share Purchase Plan (the “ESPP”) is accounted for at fair value on the date of grant using the Black-Scholes option valuation model.

Advertising

Advertising expenditures are expensed as incurred. Advertising expense was $0.6 million, $0.5 million and $0.2 million in the fiscal years ended June 30, 2024, 2023, and 2022, respectively.

Comprehensive Income (Loss)

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

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%. Also, the Company’s right to designate directors on the board of the JV Company was reduced to three (3) out of seven (7) directors, from four (4) directors prior to the Transaction. As a result of the Transaction and other factors, the Company no longer has a controlling financial interest in the JV Company and has determined that the JV Company was deconsolidated from the Company’s consolidated financial statements effective as of the Closing Date. In connection with the deconsolidation and in accordance with ASC 810, the Company recorded a gain on deconsolidation of $399.1 million during the fiscal year ended June 30, 2022 in the condensed consolidated statements of operations.The gain on deconsolidation of the JV Company was calculated as follows:

(in thousands)

Cash received for sales of shares in the JV Company $ 16,924

Fair value of retained equity method investment 393,124

Carrying amount of non-controlling interest 143,889

Cumulative translation adjustment removal 1,793

Carrying amount of net assets of the JV Company at December 1, 2021 (156,637)

Gain on deconsolidation of the JV Company $ 399,093

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

On January 26, 2022, the JV Company completed a financing transaction pursuant to a corporate investment agreement (the “Investment Agreement”) between the JV Company and certain third-party investors (the “New Investors”). Under the Investment Agreement, the New Investors purchased newly issued equity interest of the JV Company, representing approximately 7.82% of post-transaction outstanding equity interests of the JV Company, for a total purchase price of RMB 509 million (or approximately USD 80 million based on the currency exchange rate as of January 26, 2022) (the “Investment”). Following the closing of the Investment and as of June 30, 2022, the percentage of outstanding JV equity interest beneficially owned by the Company was reduced to 42.2%.

The net loss associated with these sales of JV Company equity interest held by the Company was recorded in the fiscal year ended June 30, 2022 as follows:

(in thousands)

Gain on 1.1% equity interest sold $ 475

Gain on 7.82% equity interest sold 4,501

Loss on changes on equity interest of the JV Company, net $ (3,140)

The Company accounts for its investment in the JV Company as an equity method investment and reports its equity in earnings or loss of the JV Company on a three-month lag due to an inability to timely obtain financial information of the JV Company. During the fiscal years ended June 30, 2024, 2023 and 2022, the Company recorded $4.8 million, $1.4 million and $2.6 million of its equity in loss of the JV Company, respectively, using lag reporting.

Summarized Financial Information

The following table presents summarized financial information for the JV Company (in thousands):

3. Related Party Transactions

As of June 30, 2024, the Company owned 42.8% equity interest in the JV Company, which, by definition, is a related party to the Company. The JV Company supplies 12-inch wafers and provides assembly and testing services to AOS. AOS previously sold 8-inch wafers to the JV Company for further assembly and testing services until January 1, 2023, when it changed to consign the 8-inch wafers to the JV Company. Due to the right of offset of receivables and payables with the JV Company, as of June 30, 2024 and 2023, AOS recorded the net amount of $13.7 million and $12.0 million, respectively, as a payable related to equity investee, net, on the Consolidated Balance Sheet. Since the December 2, 2021 deconsolidation of the JV Company and through the fiscal year ended June 30, 2022, the Company purchased finished goods and services of $117.6 million from the JV Company and AOS provided the JV Company with $36.4 million of 8-inch wafers. The purchases by AOS for the fiscal year ended June 30, 2023 were $127.8 million and the sales by AOS for the fiscal year ended June 30, 2023 were $35.6 million. The purchases by AOS for the fiscal year ended June 30, 2024 were $96.6 million and the sales by AOS for the fiscal year ended June 30, 2024 were $9.8 million.

4. Net Income (Loss) Per Common Share Attributable to Alpha and Omega Semiconductor Limited

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

The following table presents the calculation of basic and diluted net income (loss) per share attributable to common shareholders:

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 of credit approvals, credit ratings and other monitoring procedures. In some instances, the Company also obtains letters of credit from certain customers.

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

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

Year Ended June 30,

Customer D * 14.0 % *
