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.

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

43

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

44

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

45

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

46

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.

Revenue

The following is a summary of revenue by product type:

The following is a summary of revenue by end market:

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

49

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 and gross profit

Fiscal 2024 vs 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

Fiscal 2024 vs 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

50

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.

Selling, general and administrative expenses

Fiscal 2024 vs 2023

Selling, general and administrative expenses were $85.7 million for fiscal year 2024, a decrease of $3.1 million, or 3.5%, as compared to $88.9 million for fiscal year 2023. The decrease was primarily attributable to a $9.2 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, partially offset by a $1.5 million increase in employee compensation and benefits expenses mainly due to increased headcount and higher bonus expense and vacation expense, offset by lower business insurance expenses, a $1.0 million increase in consulting fees, a $1.0 million increase in audit fees, a $1.8 million increase in allocation expenses and $0.7 million increase in employee business expenses.

Fiscal 2023 vs 2022

Selling, general and administrative expenses were $88.9 million for fiscal year 2023, a decrease of $6.4 million, or 6.7%, as compared to $95.3 million for fiscal year 2022. The decrease was primarily attributable to a $11.3 million decrease in employee compensation and benefits expenses mainly due to lower bonus expenses accrual and lower vacation accrual, partially offset by increased headcount, higher medical and business insurance expenses, as well as a $1.5 million decrease in loss incurred in connection with a cyber security incident, partially offset by a $3.1 million increase in share-based compensation expense due to an increase in stock award granted and the incremental expenses for one of our former officers' equity shares resulting from the modification, a $1.1 million increase in legal expenses, a $0.7 million increase in recruiting and consulting fees, a $1.2 million increase in allocation expenses, and a $0.8 million increase in employee business expenses.

Other income (loss), net

Other income (loss), net decreased by $1.7 million in fiscal year 2024 as compared to the last fiscal year primarily due to decrease in foreign currency exchange loss as a result of the appreciation of RMB against USD.

Other income (loss), net increased by $2.7 million in fiscal year 2023 as compared to the last fiscal year primarily due to increase in foreign currency exchange loss as a result of the depreciation of RMB against USD.

Interest income (expense), net

51

Interest income (expense), net increased by $2.3 million in fiscal year 2024 as compared to the prior fiscal year primarily due to a $1.4 million increase in interest income as a result of higher interest rate as well as a $0.9 million decrease in interest expense as a result of a decrease in bank borrowings during the fiscal year 2024.

Interest income (expense), net decreased by $2.8 million in fiscal year 2023 as compared to the fiscal year 2022 primarily due to a $3.6 million increase in interest income as a result of higher interest rate, offset by a $0.7 million increase in interest expense as a result of an increase in bank borrowings during the fiscal year 2023.

Income tax expense

Fiscal 2024 vs 2023

Income tax expense for fiscal years 2024 and 2023 was $3.6 million and $5.9 million, respectively. 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

53

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.

54

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

Cash flows from operating activities

56

Contractual Obligations

Our contractual obligations as of June 30, 2024 are as follows:

As of June 30, 2024, we had recorded liabilities of $3.0 million for uncertain tax positions and $0.5 million for potential interest and penalties, which are not included in the above table because we are unable to reliably estimate the amount of payments in individual years that would be made in connection with these uncertain tax positions.

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.

57

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

58

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.

59

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 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 power discretes, ICs, modules and digital power solutions including a wide portfolio of Power MOSFET, SiC, IGBT,IPM, TVS, Gate Drivers, Power IC, and Digital Power products. Our portfolio of power semiconductors includes approximately 2,600 products, and has grown significantly with the introduction of over 60 new products in the fiscal year ended June 30, 2023, and over 130 and 160 new products in the fiscal year ended June 30, 2022 and 2021, 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 918 patents and 45 patent applications in the United States as of June 30, 2023. We also have a total of 980 foreign patents, which primarily were based on our research and development efforts through June 30, 2023. 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.

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 the JV Company with the Chongqing Funds, for the purpose of constructing and operating the Chongqing Fab in the LiangJiang New Area of Chongqing, China. The Chongqing Fab was being built in phases. As of December 1, 2021, we owned 50.9%, and the Chongqing Funds owned 49.1% of the equity interest in the JV Company. The JV Company was accounted under the provisions of the consolidation guidance since we had controlling financial interest 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 and has determined that 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 us 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.

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 January 26, 2022 Investment, the percentage of outstanding JV equity interest beneficially owned by the Company was reduced to 42.2% at both June 30, 2022 and 2023.

42

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 provided us with a monthly wafer production capacity guarantee, subject to future increase when the JV Company’s production capacity reaches certain specified level.

Impact of COVID-19 Pandemic to Our Business

During the first half of calendar year 2022, our operations were negatively impacted by China’s zero-Covid policy that resulted in factory shutdowns and supply chain shortages, including the temporary suspension of our factory operations in Shanghai from April to June 2022. In December 2022, the Chinese government issued new guidelines easing some of its strict zero-COVID policies, including the relaxation of testing requirements and travel restrictions. In May 2023, World Health Organization (WHO) declared an end to the COVID-19 pandemic. As of June 30, 2023, our business operations and financial performance were no longer affected by the pandemic.

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. Since mid-2022, we have experienced an industry-wide decline of customer demand for semiconductor products. This decline has negatively affected our recent financial performance in 2023. While we expect some continued recovery of our revenue in the September quarter of 2023, there is no guarantee that it will occur. A prolonged and extended downturn in the semiconductor industry would have a substantial impact on our operating results and financial conditions.

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

Manufacturing costs and capacity availability: Our gross margin is affected by a number of factors including our manufacturing costs, utilization of our manufacturing facilities, the product mixes of our sales, pricing of wafers from third party foundries and pricing of semiconductor raw materials. Capacity utilization affects our gross margin because we have certain fixed costs at our Shanghai facilities and our Oregon Fab. If we are unable to utilize our manufacturing facilities at a desired level, our gross margin may be adversely affected. In addition, from time to time, we may experience wafer capacity constraints, particularly at third party foundries, that may prevent us from meeting fully the demand of our customers. For example, the recent global shortage of semiconductor manufacturing capacity has provided us with both challenges and opportunities in the market, and highlighted the importance of maintaining sufficient and independent in-house manufacturing capabilities to meet increasing customer demands. While we can mitigate these constraints by increasing and re-allocating capacity at our own fab, we may not be able to do so quickly or at sufficient level, which could adversely affect our financial conditions and results of operations. In addition, we enhanced the manufacturing capability and capacity of our Oregon Fab by investing in new equipment and expanding our factory facilities, which we expect will have a positive impact on our future new product development and revenue, particularly during the period of global shortage of capacity. We also rely substantially on the JV Company to provide foundry capacity to manufacture our products, therefore it is critical that we maintain continuous access to such capacity, which may not be available at sufficient level or at a pricing terms favorable to us because of lack of control over the JV Company’s operation. As a result of sales of our JV Company equity interests and issuance of additional equity interests by the JV Company to third-party investors in financing transactions, our equity interest in the JV Company was reduced to 42.2%, which reduced our control and influence over the JV Company. We continue to maintain a business relationship with the JV Company to ensure uninterrupted supply of manufacturing capacity. On July 12, 2022, we entered into an agreement with the JV Company, pursuant to which the JV Company agrees to provide us with a monthly wafer production capacity guarantee, subject to future increase when the JV Company’s production capacity reaches certain specified level.

43

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

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

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

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 subsidiaries.

Our product revenue is reported net of the effect of the estimated stock rotation returns and price adjustments that we expect to provide to our distributors. Stock rotation returns are governed by contract and are limited to a specified percentage of the monetary value of products purchased by the distributor during a specified period. At our discretion or upon our direct negotiations with the original design manufacturers (“ODMs”) or original equipment manufacturers (“OEMs”), we may elect to grant special pricing that is below the prices at which we sold our products to the distributors. In 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, pre-approved future 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 million, consisting of an upfront fee of $18 million and 6.8 million paid to us in the March and July 2023, with the remaining amount to be paid upon the achievement of

44

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 of the transfer of services. 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

45

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.

"U.S. Coronavirus Aid, Relief and Economic Security Act” (“CARES Act”), Enacted March 27, 2020

On March 27, 2020, the United States enacted the CARES Act, which made the changes to existing U.S. tax laws, including, but not limited to, (1) allowing U.S. federal net operating losses originated in the 2018, 2019 or 2020 tax years to be carried back five years to recover taxes paid based upon taxable income in the prior five years, (2) eliminated the 80% of taxable income limitation on net operating losses for the 2018, 2019 and 2020 tax years (the 80% limitation will be reinstated for tax years after 2020), (3) accelerating the refund of prior year alternative minimum tax credits, (4) modifying the bonus depreciation for qualified improvement property and (5) modifying the limitation on deductible interest expense.

As a result of the ability to carryback net operating losses from the June 2018 and June 2019 years to the June 2015 to June 2017 tax years, net operating losses which were previously tax-effected using the current 21% U.S. federal tax rate were revalued to the U.S. tax rates in effect for the June 2015 to June 2017 tax years due to the ability of receiving tax refunds for the taxes paid in these years. Accordingly, we reported a discrete tax benefit of $1.1 million in the third quarter of fiscal year 2020 related to the re-measurement of the net operating losses that could be realized via the new net operating loss carryback provisions.

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

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

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

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

“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.

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

46

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.

Revenue

The following is a summary of revenue by product type:

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. During fiscal year 2023, we accelerated the development of new technology platforms which allowed us to introduce 19 medium and high voltage MOSFET products, targeting primarily the industrial markets and communication marketing, and 6 module products primarily for the consumer markets, as well as 4 low voltage MOSFET products primarily for the computing and communication markets. In addition, we introduced 40 Power IC new products for computing applications, communication and consumer markets.

Fiscal 2022 vs 2021

Total revenue was $777.6 million for fiscal year 2022, an increase of $120.7 million, or 18.4%, as compared to $656.9 million for fiscal year 2021. The increase was primarily due to an increase of $62.4 million in sales of power discrete products and an increase of $59.2 million in sales of power IC products. The increase in power discrete and power IC product sales was primarily due to a 21.0% increase in average selling price as compared to last fiscal year due to a shift in product mix, partially offset by a 2.1% decrease in unit shipments. The decrease in revenue of packaging and testing services for the fiscal year 2022 as compared to last fiscal year was primarily due to decreased demand.

49

Cost of goods sold and gross profit

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. 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 2022 vs 2021

Cost of goods sold was $509.0 million for fiscal year 2022, an increase of $56.6 million, or 12.5%, as compared to $452.4 million for fiscal year 2021. The increase was primarily due to 18.4% increase in revenue. Gross margin increased by 3.4 percentage points to 34.5% for the fiscal year 2022, as compared to 31.1% for the fiscal year 2021. The increase in gross margin was primarily due to better product mix during the fiscal year ended June 30, 2022.

Research and development expenses

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, and a $4.8 million increase in product prototyping engineering expense as a result of increased engineering activities. 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 2022 vs 2021

Research and development expenses were $71.3 million for fiscal year 2022, an increase of $8.3 million, or 13.2%, as compared to $63.0 million for fiscal year 2021. The increase was primarily attributable to a $6.8 million increase in employee compensation and benefit expense mainly due to higher bonus accrual, increased headcount and annual merit increase, a $1.7 million increase in share-based compensation expense due to an increase in stock awards granted, a $0.2 million increase in depreciation expenses, and a $0.2 million increase in professional fees, partially offset by a $0.8 million decrease in product prototyping engineering expense as a result of decreased engineering activities.

Selling, general and administrative expenses

Fiscal 2023 vs 2022

Selling, general and administrative expenses were $88.9 million for fiscal year 2023, a decrease of $6.4 million, or 6.7%, as compared to $95.3 million for fiscal year 2022. The decrease was primarily attributable to a $11.3 million decrease in employee compensation and benefits expenses mainly due to lower bonus expenses accrual and lower vacation accrual, partially offset by increased headcount, higher medical and business insurance expenses, as well as a $1.5 million decrease in cyber security incident, partially offset by a $3.1 million increase in share-based compensation expense due to an increase in stock award granted and the incremental expenses for one of our former officers' equity shares resulting from the modification, a $1.1 million increase in legal expenses, a $0.7 million increase in recruiting and consulting fees, a $1.2 million increase in allocation, and a $0.8 million increase in employee business expenses.

Fiscal 2022 vs 2021

Selling, general and administrative expenses were $95.3 million for fiscal year 2022, an increase of $17.7 million, or 22.9%, as compared to $77.5 million for fiscal year 2021. The increase was primarily attributable to a $8.6 million increase in employee compensation and benefits expenses mainly due to increased headcount, annual merit increase, higher bonus expenses and increased employee and business insurance expenses, as well as $10.9 million increase in share-based compensation expense due to increase in stock award granted, partially offset by a $2.2 million decrease in legal expense related to the government investigation.

Other income (loss), net

Other income (loss), net decreased by $2.7 million in fiscal year 2023 as compared to the last fiscal year primarily due to increase in foreign currency exchange loss as a result of the depreciation of RMB against USD.

Other income (loss), net decreased by $1.5 million in fiscal year 2022 as compared to the last fiscal year primarily due to increase in foreign currency exchange loss as a result of the depreciation of RMB against USD.

Interest expense, net

Interest expense was primarily related to bank borrowings. Interest expense decreased by $2.8 million in fiscal year 2023 as compared to the prior fiscal year primarily due to a $3.6 million increase in interest income as a result of higher interest rate, offset by a $0.7 million increase in interest expense as a result of an increase in bank borrowings during the periods.

Interest expense decreased by $2.4 million in fiscal year 2022 as compared to the fiscal year 2021 primarily because of deconsolidation of the JV Company in December 2021.

Gain on deconsolidation of the JV Company and Gain/loss on changes of equity interest in the JV Company

51

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

During the fiscal year ended June 30, 2022, we recorded a gain of $399.1 million on deconsolidation of the JV Company, and a $3.1 million of loss on changes of equity interest in the JV Company.

We account for our investment in the JV Company as an equity method investment and report our equity in earnings or loss of the JV Company on a three-month lag due to our inability to timely obtain financial information of the JV Company. For the fiscal year ended June 30, 2023 and June 30, 2022 using lag reporting, we recorded $1.4 million and 2.6 million of its equity in loss of the JV Company, respectively.

Income tax expense

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.

Fiscal 2022 vs 2021

Income tax expense for fiscal years 2022 and 2021 was $39.3 million and $3.9 million, respectively. Income tax expense increased by $35.3 million, or 897.7% in fiscal year 2022 as compared to fiscal year 2021. 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

52

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, we recorded a tax benefit of $0.4 million from other discrete income tax items. The income tax expense of $3.9 million for the year ended June 30, 2021 included a $0.3 million discrete tax benefit. Excluding the discrete income tax items ($396.0 million of income from the sale of equity interest in a joint venture and the related deconsolidation gain as well as other discrete items), the effective tax rate for the years ended June 30, 2022 and 2021 was 6.3% and 7.1%, respectively. The changes in the tax expense and effective tax rate between the periods resulted primarily from the Company reporting 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 compared to a pretax book income of $60.2 million for the year ended June 30, 2021 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.

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 million, consisted of an upfront fees of $18 million and $6.8 million paid to us in March 2023 and July 2023, 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 January 2023, one of the Company's subsidiaries in China entered into a line of credit facility with Bank of Communications Limited 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 $20.6 million based on currency exchange rate between RMB and U.S. Dollar on January 31, 2023 with a maturity date of December 1, 2023. As of June 30, 2023, there was no outstanding balance for this loan.

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 the carrying amount of $15.2 million as of June 30, 2023.

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, 2023, Jireh was in compliance with these covenants and the outstanding balance of this loan was $38.3 million.

In October 2019, one of the Company's subsidiaries in China entered into a line of credit facility with Bank of Communications Limited in China. This line of credit matured on February 14, 2021 and was based on the China Base Rate multiplied by 1.05, or 4.99% on October 31, 2019. The purpose of the credit facility is to provide short-term borrowings. The Company could borrow up to approximately RMB 60.0 million or $8.5 million based on the currency exchange rate between the RMB and the U.S. Dollar on October 31, 2019. In September 2021, this line of credit was renewed with maximum borrowings up to RMB 140.0 million with the same terms and a maturity date of September 18, 2022. During the three months ended December 31, 2021, the Company borrowed RMB 11.0 million, or $1.6 million, at an interest rate of 3.85% per annum, with principal due on November 18, 2022.

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

54

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 one month London Interbank Offered Rate ("LIBOR") plus 1.75% per annum. The Company is the guarantor for this agreement. The Company is accounting for this transaction as a secured borrowing under the Transfers and Servicing of Financial Assets guidance. In addition, any cash held in the restricted bank account controlled by HSBC has a legal right of offset against the borrowing. This agreement, with certain financial covenants required, has no expiration date. On August 11, 2021, the Borrower signed an agreement with HSBC to decrease the borrowing maximum amount to $8.0 million with certain financial covenants required. Other terms remain the same. The Borrower was in compliance with these covenants as of June 30, 2023. As of June 30, 2023, there was no outstanding balance and the Company had unused credit of approximately $8.0 million.

As of June 30, 2023, there was no outstanding balance and this loan was expired.

On May 1, 2018, Jireh entered into a loan agreement with the Bank that provided a term loan in an amount of $17.8 million. The obligation under the loan agreement is secured by certain real estate assets of Jireh and guaranteed by the Company. The loan has a five-year term and matures on June 1, 2023. Jireh made consecutive monthly payments of principal and interest to the Bank. The outstanding principal shall accrue interest at a fixed rate of 5.04% per annum on the basis of a 360-day year. The loan agreement contains customary restrictive covenants and includes certain financial covenants that require the Company to maintain, on a consolidated basis, specified financial ratios. In August 2021, Jireh signed an amendment of this loan with the Bank to modify the financial covenants requirement to align with the new term loan agreement entered into on August 18, 2021 discussed above. The amendment was accounted for as a debt modification and no gain or loss was recognized. The Company paid this loan in full on May 1, 2023. As of June 30, 2023, there was no outstanding balance and this loan was expired.

On August 15, 2017, Jireh entered into a credit agreement with the Bank that provided a term loan in an amount up to $30.0 million for the purpose of purchasing certain equipment for the fabrication facility located in Oregon.

The credit agreement contained customary restrictive covenants and included certain financial covenants that required the Company to maintain, on a consolidated basis, specified financial ratios and fixed charge coverage ratio. In August 2021, Jireh signed an amendment of this loan with the Bank to modify the financial covenants requirement to align with the new term loan agreement entered into on August 18, 2021, discussed above. The amendment was accounted for as a debt modification and no gain or loss was recognized. The loan was fully paid off in September, 2022. As of June 30, 2023, there was no outstanding balance and this loan was expired.

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. In calculating accumulated profits, foreign-invested enterprises in China are required to allocate 10% of their profits each year, if any, to fund the equity reserve account unless the reserve has reached 50% of the registered capital of the enterprises. 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.

55

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, 2023 and 2022, such restricted portion amounted to approximately $93.2 million and $92.4 million, or 10.5% and 10.8%, 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, 2023 and 2022, we had $195.6 million and $314.7 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 $195.6 million and $314.7 million cash and cash equivalents, $108.2 million and $212.6 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:

Contractual Obligations

Our contractual obligations as of June 30, 2023 are as follows:

As of June 30, 2023, we had recorded liabilities of $2.5 million for uncertain tax positions and $0.3 million for potential interest and penalties, which are not included in the above table because we are unable to reliably estimate the amount of payments in individual years that would be made in connection with these uncertain tax positions.

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, 2023, we had no off-balance sheet arrangements.

58

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, pre-approved 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 million, consisting of an upfront fee of $18 million and $6.8 million paid to us in March 2023 and July 2023, 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 year ended June 30, 2023, we recorded $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

59

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 period of April 1, 2022 to March 31, 2023 was recorded in our Consolidated Statement of Operations for the fiscal year ended June 30, 2023. 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 have not provided for withholding taxes on the undistributed earnings of our foreign subsidiaries because we intend to reinvest such earnings indefinitely. However, we have recorded a deferred tax liability of $27.9 million at June 30, 2023 related to our investment in the JV Company. As of June 30, 2023, the cumulative amount of undistributed earnings of our foreign subsidiaries considered permanently reinvested was $374 million. The determination of the unrecognized deferred tax liability on these earnings is not practicable. Should we decide to remit this income to the Bermuda parent company in a future period, our provision for income taxes may increase materially in that period.

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

60

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 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 portfolio of power semiconductors. Our portfolio of power semiconductors includes approximately 2,500 products, and has grown significantly with the introduction of over 130 new products in the fiscal year ended June 30, 2022, and over 160 new products in each of the fiscal year ended June 30, 2020 and 2019, 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 888 patents and 62 patent applications in the United States as of June 30, 2022. We also have a total of 936 foreign patents, which primarily were based on our research and development efforts through June 30, 2022. 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.

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 the JV Company with the Chongqing Funds, for the purpose of constructing and operating the Chongqing Fab in the LiangJiang New Area of Chongqing, China. The Chongqing Fab is being built in phases. As of December 1, 2021, we owned 50.9%, and the Chongqing Funds owned 49.1% of the equity interest in the JV Company. The JV Company was accounted under the provisions of the consolidation guidance since we had controlling financial interest until December 1, 2021.

Effective December 1, 2021, we entered into a share transfer agreement ("STA") with a third-party investor (the "Investor"), pursuant to which we sold to the Investor approximately 2.1% of outstanding equity interest held by us in the JV Company for an aggregate purchase price of RMB 108 million or approximately $16.9 million. The STA contained customary representations, warranties and covenants. The Transaction was closed on December 2, 2021. As a result of the Transaction, as of the Closing Date, our equity interest in the JV Company decreased from 50.9% to 48.8%. Also, our right to designate directors on the board of JV Company was reduced to three (3) out of seven (7) directors, from four (4) directors prior to the Transaction. As of December 2, 2021, we no longer have a controlling financial interest in the JV Company under generally accepted accounting principles. Loss of control is deemed to have occurred when, among other things, a parent company owns less than a majority of the outstanding common stock in the subsidiary, lacks a controlling financial interest in the subsidiary and, is unable to unilaterally control the subsidiary through other means such as having, or the ability to obtain or represent, a majority of the subsidiary’s board of directors. All of these loss of control factors were present for us as of December 2, 2021. Accordingly, since December 2, 2021, we have deconsolidated the JV Company in our Consolidated Financial Statements and accounted for our investment in the JV Company using the equity method of accounting.

On December 24, 2021, we entered into a share transfer agreement with another third-party investor, pursuant to which we sold to this investor 1.1% of outstanding equity interest held by us in the JV Company for an aggregate purchase price of RMB 60 million or approximately $9.4 million based on the currency exchange rate as of December 24, 2021. In addition, on December 30, 2021, the JV Company adopted an employee equity incentive plan and issued an equity interest equivalent to 3.99% of the JV Company to exchange in cash. As a result, we owned 45.8% of the equity interest in the JV Company as of December 31, 2021.

On January 26, 2022, the JV Company completed a financing transaction pursuant to the Financing Agreement between the JV Company and certain New Investors. Under the Financing Agreement, the New Investors purchased newly issued equity interest of the JV Company for a total purchase price of RMB 509 million (or approximately $80 million based on the currency

46

exchange rate as of January 26, 2022) (the "Investment"). Following the closing of the Investment, the percentage of outstanding JV Company equity interest beneficially owned by the Company was reduced to 42.2%.

We reduced our ownership of the JV Company to below 50% to increase the flexibility of the JV Company to raise capital to fund its future expansion. Following the Transaction and the successful ramp up to its Phase I target run rate in the September quarter of 2021, as planned, the JV Company commenced an effort to raise up to $200 million of additional capital, including an $80 million round that was completed on January 26, 2022 through private funding for its Phase II expansion. In addition to immediate private funding rounds, the JV Company is also contemplating an eventual listing on the Science and Technology Innovation Board, or STAR Market, of the Shanghai Stock Exchange. The Transaction assists the JV Company in meeting certain regulatory listing requirements. A potential STAR Market listing may take several years to consummate and there is no guarantee that such listing by the JV Company will be successful or will be completed in a timely manner, or at all. In addition, the JV Company will continue to provide us with significant level of foundry capacity to enable us to develop and manufacture our products. On July 12, 2022, the current shareholders of the JV Company entered into a shareholders contract, pursuant to which the JV Company provided us a monthly wafer production capacity guarantee, subject to future increase when the JV Company’s production capacity reaches certain goal.

During the fiscal year ended June 30, 2022, we continued our diversification program by developing new silicon and packaging platforms to expand our serviceable available market, or SAM and offer higher performance products. Our metal-oxide-semiconductor field-effect transistors, or MOSFET, and power IC product portfolio expanded significantly. Our high performance products and deepened customer relationships with our OEM and ODM customers have contributed to the achievement of our record high revenue of $777.6 million for the fiscal year 2022, a 18.4% growth compared to the last fiscal year.

Impact of COVID-19 Pandemic to our Business

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

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

Since the start of the second quarter of calendar year 2021, there have been increasing availability and administration of vaccines against COVID-19, as well as an easing of restrictions on social, business, travel, and government activities and functions, and a gradual resumption of economic activities and consumer spending in our industries. However, infection rates continued to fluctuate in various regions and new strains of the virus remain a risk, including a surge of COVID-19 cases and hospitalization due to the spread of Omicron variants in late 2021 and early 2022. During the first half of calendar year 2022, COVID-19 cases and hospitalization rate continued to decline and governments in various jurisdictions, including the U.S. and Europe, have lifted various restrictions and limitations on economic activities. At the same time, however, new variants of COVID-19 continued to emerge and contributed to recent rise of infection rates in various jurisdictions in which we operate, including China and U.S. Furthermore, we may be subject to the ongoing global impacts resulting from the pandemic, including disruption of the product supply chains, shortages of semiconductor components, and delays in shipments, product development, and product launches and rising inflation rates.

In April 2022, the operations of our two packaging and testing facilities in Shanghai, China were suspended due to a strict lockdown of the city imposed by the local government in response to surging COVID cases. Our facilities in Shanghai were required to shut down and production was halted beginning in early April. Transportation suspension in and out of Shanghai also interrupted the shipping of raw materials and finished parts to and from our facilities. We received permission to reopen our facilities partially in early May. We gradually ramped up production at these facilities in May and returned to normal operation in June 2022. The suspension of our Shanghai facilities, and the subsequent partial resumption of production,

47

reduced our ability to complete orders from our customers in a timely manner, which adversely affected our revenue and results of operation for the three months ended June 30, 2022. We cannot guarantee that the Shanghai government will not impose similar restrictions and lockdown in the future, and any such restrictions and lockdown will adversely affect our operations and financial performance.

The full extent of the longer-term impact of the COVID-19 pandemic on our operational and financial performance is uncertain and will depend on many factors outside our control, including, without limitation, the timing, extent, trajectory and duration of the pandemic; the availability, distribution and effectiveness of vaccines; the spread of new variants of COVID-19; the continued and renewed imposition of protective public safety measures, including local and regional lockdown and quarantines; the disruption of global supply chain; and the impact of the pandemic on the global economy and demand for consumer products. Although we are unable to predict the full impact and duration of the COVID-19 pandemic on our business, we are actively managing our business operations and financial expenditures in response to continued uncertainty.

Other Factors affecting our performance

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

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

Manufacturing costs and capacity availability: Our gross margin is affected by a number of factors including our manufacturing costs, utilization of our manufacturing facilities, the product mixes of our sales, pricing of wafers from third party foundries and pricing of semiconductor raw materials. Capacity utilization affects our gross margin because we have certain fixed costs at our Shanghai facilities and our Oregon Fab. If we are unable to utilize our manufacturing facilities at a desired level, our gross margin may be adversely affected. For example, in April 2022, the operations of our packaging and testing facilities in Shanghai, China were suspended due to a strict lockdown of the city imposed by the local government in response to surging COVID cases. The facilities were required to be shut down and production was halted since early April. Transportation suspension in and out of Shanghai also interrupted the shipping of raw materials and finished parts to and from our facilities. We received permission to reopen our facilities partially in early May. We gradually ramped up production at these facilities in May and returned to normal operation in June 2022. However, there is no guarantee that additional restrictions and lockdown will not be reimposed by the government, which is outside of our control, and any extension of the lockdown will continue to have a negative impact on our results of operation and financial condition. In addition, from time to time, we may experience wafer capacity constraints, particularly at third party foundries, that may prevent us from meeting fully the demand of our customers. For example, the recent global shortage of semiconductor manufacturing capacity has provided us with both challenges and opportunities in the market, and highlighted the importance of maintaining sufficient and independent in-house manufacturing capabilities to meet increasing customer demands. While we can mitigate these constraints by increasing and re-allocating capacity at our own fab, we may not be able to do so quickly or at sufficient level, which could adversely affect our financial conditions and results of operations. In addition, we recently commenced a plan to enhance the manufacturing capability and capacity of our Oregon Fab by investing in new equipment and expanding our factory facilities, which we expect will have a positive impact on our future new product development and revenue, particularly during the period of global shortage of capacity. The expansion is expected to be completed in the fiscal quarter ending March 31, 2023. We also rely substantially on the JV Company to provide foundry capacity to manufacture our products, therefore it is critical that we maintain continuous access to such capacity, which may not be available at sufficient level or at a pricing terms favorable to us because of lack of control over the JV Company’s operation. As a result of sales of our JV Company equity interests and issuance of additional equity interests by the JV Company to third-party investors in financing transactions, our

48

equity interest in the JV Company was reduced to 42.2%, which reduced our control and influence over the JV Company. While we continue to maintain a business relationship with the JV Company to ensure uninterrupted supply of manufacturing capacity, and we are currently negotiating a foundry agreement for the JV Company to provide guarantee level of capacity, the JV Company may take actions or make decisions that adversely impact our ability to access required capacity, and our lack of control and influence may prevent us from eliminating or mitigating such risk.

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

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

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

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 subsidiaries.

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

49

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

50

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.

U.S. Coronavirus Aid, Relief and Economic Security Act” (“CARES Act”), Enacted March 27, 2020

On March 27, 2020, the United States enacted the CARES Act, which made the changes to existing U.S. tax laws, including, but not limited to, (1) allowing U.S. federal net operating losses originated in the 2018, 2019 or 2020 tax years to be carried back five years to recover taxes paid based upon taxable income in the prior five years, (2) eliminated the 80% of taxable income limitation on net operating losses for the 2018, 2019 and 2020 tax years (the 80% limitation will be reinstated for tax years after 2020), (3) accelerating the refund of prior year alternative minimum tax credits, (4) modifying the bonus depreciation for qualified improvement property and (5) modifying the limitation on deductible interest expense.

As a result of the ability to carryback net operating losses from the June 2018 and June 2019 years to the June 2015 to June 2017 tax years, net operating losses which were previously tax-effected using the current 21% U.S. federal tax rate were revalued to the U.S. tax rates in effect for the June 2015 to June 2017 tax years due to the ability of receiving tax refunds for the taxes paid in these years.
