RISK FACTORS

An investment in our common stock involves risks. You should consider these risks carefully, as well as the other information contained in this prospectus. If any of these risks actually occurs, our business, financial condition and results of operations could be harmed materially. In that event, the trading price of our common stock might decline, and you might lose all or part of your investment. You should also refer to the other information contained in this prospectus, including our consolidated financial statements and the related notes. Additional risks and uncertainties not presently known to us or not believed by us to be material may also negatively impact us.

Risks Related to Our Business and Industry

Downturns or volatility in general economic conditions, including as a result of the current COVID-19 pandemic or any other outbreak of an infectious disease, could have a material adverse effect on our business, financial condition, results of operations and liquidity.

Our net sales, gross margin, and profitability depend significantly on general economic conditions and the demand for products in the markets in which our customers compete. Weaknesses in the global economy and financial markets, including the current weaknesses resulting from the ongoing COVID-19 pandemic, have led to, and any adverse changes in general domestic and global economic conditions that may occur in the future, including any recession, economic slowdown or disruption of credit markets, may also lead to, lower demand for products that incorporate our solutions, particularly in the automotive and industrial markets. A decline in end-user demand can affect our customers’ demand for our products, the ability of our customers to obtain credit and otherwise meet their payment obligations and the likelihood of customers canceling or deferring existing orders. Our net sales, financial condition and results of operations could be negatively affected by such actions.

Volatile and/or uncertain economic conditions can adversely impact sales, gross margin and profitability and make it difficult for us to accurately forecast and plan our future business activities. To the extent we incorrectly plan for favorable economic conditions that do not materialize or take longer to materialize than expected, we may face oversupply of our products relative to customer demand. Conversely, if we underestimate customer demand, we may manufacture products that we may not be able to sell. As a result, we would have excess inventory, which could result in losses. To the extent that our sales, profitability and strategies are negatively affected by downturns or volatility in general economic conditions, our business, financial condition and results of operations may be materially and adversely affected.

In addition, any disruption in the credit markets, including as a result of the current COVID-19 pandemic, could impede our access to capital, which could be further adversely affected if we are unable to obtain or maintain favorable credit ratings. If we have limited access to additional financing sources, we may be required to defer capital expenditures or seek other sources of liquidity, which may not be available to us on acceptable terms or at all. Similarly, if our suppliers face challenges in obtaining credit or other financial difficulties, they may be unable to provide the materials we need to manufacture our products. All of these factors related to global economic conditions, which are beyond our control, could adversely impact our business, financial condition, results of operations and liquidity. For a more detailed discussion of the COVID-19 pandemic and its recent and potential impact on our business, financial condition, results of operations and liquidity, see “—Our business, financial condition, results of operations, liquidity and prospects have been, and may continue to be, adversely affected by health epidemics, pandemics and other outbreaks of infectious disease, including the current COVID-19 pandemic.”

We face intense competition and may not be able to compete effectively, which could reduce our market share and decrease our net sales and profitability.

We are engaged in an intensely competitive segment of the global semiconductor industry. Our competitive landscape includes rapid technological change in product design and manufacturing, continuous declines in

29

ASPs, and customers that make purchase decisions based on a mix of factors of varying importance. The most important competitive factors that we face are time to market, system and application expertise and product quality and reliability. The relative importance placed on each of these factors varies from customer-to-customer and from market-to-market. Our ability to compete in this environment depends on many factors, including our ability to identify emerging markets and technology trends in an accurate and timely manner, introduce new and innovative products, implement new manufacturing technologies at a sustainable pace, maintain the performance and quality of our products, and manufacture our products in a cost-effective manner, as well as our competitors’ performance and general economic and industry market conditions.

Often, we compete against larger companies that possess substantial financial, technical, development, engineering, manufacturing and marketing resources. Varying combinations of these resources provide advantages to these competitors that enable them to influence industry trends and the pace at which they adapt to these trends. A strong competitive response from one or more of our competitors to our marketplace efforts, or a shift in customer preferences to competitors’ products, could result in increased pressure to lower our prices more rapidly than anticipated, increased sales and marketing expense, and/or market share loss. To the extent our profitability is negatively impacted by competitive pressures and reduced pricing, our business, financial condition, results of operations and growth prospects may be materially and adversely affected.

Decreases in average selling prices of our products may reduce our gross margins.

The market for our products is generally characterized by declining ASPs resulting from factors such as increased competition, overcapacity, the introduction of new products and increased unit volumes. We have in the past experienced, and in the future may experience, substantial period-to-period fluctuations in operating results due to declining ASPs. We anticipate that ASPs may decrease in the future in response to the introduction of new products by us or our competitors, or due to other factors, including pricing pressures from our customers. We typically conduct annual pricing negotiations for our existing products with some of our largest customers. In order to sustain profitable operations, we must continually reduce costs for our existing products and also develop and introduce new products with enhanced features on a timely basis that can be sold initially at higher ASPs. Failure to do so could cause our net sales and gross margins to decline, which would negatively affect our financial condition and results of operations and could significantly harm our business.

We may be unable to reduce the cost of our products sufficiently to enable us to compete with others. Our cost reduction efforts may not allow us to keep pace with competitive pricing pressures and could adversely affect our gross margins. We maintain an infrastructure of facilities and human resources in several locations around the world and, as a result, have limited ability to reduce our operating costs. Accordingly, in order to remain competitive, we must continually reduce the cost of manufacturing our products through design and engineering changes. We cannot assure you that we will be successful in redesigning our products and bringing redesigned products to the market in a timely manner, or that any redesign will result in sufficient cost reductions to allow us to reduce the price of our products to remain competitive or maintain or improve our gross margins. To the extent we are unable to reduce the prices of our products and remain competitive, our net sales will likely decline, resulting in further pressure on our gross margins, which could have a material adverse effect on our business, financial condition and results of operations and our ability to grow our business.

The cyclical nature of the analog semiconductor industry may limit our ability to maintain or improve our net sales and profitability.

The semiconductor industry, including the analog segment of the industry in which we compete, is highly cyclical and is prone to significant downturns from time to time. Cyclical downturns can result from a variety of market forces including constant and rapid technological change, rapid product obsolescence, price erosion, evolving standards, short product life cycles and wide fluctuations in product supply and demand, all of which can result in significant declines in analog semiconductor demand. We have experienced downturns in the past and may experience such downturns in the future. For example, the industry experienced a significant downtown

30

in connection with the most recent global recession in 2008, and further experienced a downturn in 2019, which may be prolonged as a result of the economic impact of the COVID-19 pandemic. These downturns have been characterized by diminished product demand, production overcapacity, high inventory levels and accelerated erosion of average selling prices. Recently, downturns in the semiconductor industry have been attributed to a variety of factors, including the current COVID-19 pandemic, ongoing trade disputes among the United States and China, weakness in demand and pricing for semiconductors across applications and excess inventory. Recent downturns have directly impacted our business, as has been the case with many other companies, suppliers, distributors and customers in the semiconductor industry and other industries around the world, and any prolonged or significant future downturns in the semiconductor industry could have a material adverse effect on our business, financial condition and results of operations. Conversely, significant upturns can cause us to be unable to satisfy demand in a timely and cost-efficient manner and could result in increased competition for access to third-party foundry and assembly capacity. In the event of such an upturn, we may not be able to expand our workforce and operations in a sufficiently timely manner, procure adequate resources and raw materials, or locate suitable third-party suppliers or other third-party subcontractors to respond effectively to changes in demand for our existing products or to the demand for new products requested by our customers, and our business, financial condition and results of operations could be materially and adversely affected.

Substantial portions of our sales are made to automotive industry suppliers. Any downturn in the automotive market could significantly harm our financial results.

Our customers that supply various systems and components to automotive OEMs accounted for approximately 61.4% and 60.8% of our total net sales in fiscal years 2019 and 2020, respectively, and approximately 72.3% and 72.9% of our total net sales in such fiscal years after excluding net sales from our wafer foundry products and our distribution of Sanken products which, in each case, we will not recognize in periods following fiscal year 2020 due to our consummation of the Divestiture Transactions. Our net sales to such customers accounted for approximately 60.6% of our total net sales during the three-month period ended June 28, 2019 (or approximately 72.9% of our total net sales in such period after excluding net sales from our wafer foundry products and our distribution of Sanken products) and approximately 66.4% of our total net sales during the three-month period ended June 26, 2020. This concentration of sales exposes us to the risks associated with the automotive market. For example, our anticipated future growth is highly dependent on the adoption of autonomous driving technologies, which are expected to have increased sensor and power product content. A downturn in the automotive market could delay automakers’ plans to introduce new vehicles with these features, which would negatively impact the demand for our products and our ability to grow our business.

The automotive industry is also undergoing consolidation and reorganization and, in some cases, suppliers to the automotive industry have entered bankruptcy. Although we have not experienced any lost business or material bad debt write-offs as a result of this, further such changes in the automotive market could have a material adverse effect on our business, financial condition and results of operations.

Moreover, as a result of the COVID-19 pandemic and the associated responses by governments of various countries to prevent its spread, the automotive industry, including manufacturers, dealers, distributors and third-party suppliers has been adversely impacted. For example, many automotive manufacturers were forced to suspend manufacturing operations and have only recently resumed production. In addition, government-imposed restrictions on businesses, operations and travel and the related economic uncertainty have impacted demand in many global markets. While demand in the automotive industry is dependent on a number of factors, automotive manufacturers expect the impact of COVID-19 to be highly dependent on its duration and severity. The foregoing impacts and other adverse effects on the automotive industry could have a material adverse effect on our business, financial condition and results of operations, as well as our ability to execute our growth strategy.

Shifts in our product mix or customer mix may result in declines in gross margin.

Gross margins on individual products fluctuate over the product’s life cycle. Our overall gross margins have fluctuated from period to period as a result of shifts in product mix, customer mix, the introduction of new

31

products, decreases in ASPs for older products and our ability to reduce product costs. These fluctuations are expected to continue in the future.

If we encounter sustained yield problems or other delays at our third-party wafer fabrication facilities or in the final assembly and test of our products, we may lose sales and damage our customer relationships.

The manufacture of our products, including the fabrication of semiconductor wafers, and the assembly and testing of our products, involve highly complex processes. For example, minute levels of contaminants in the manufacturing environment, difficulties in the wafer fabrication process or other factors can cause a substantial portion of the components on a wafer to be nonfunctional. These problems may be difficult to detect at an early stage of the manufacturing process and often are time-consuming and expensive to correct. From time to time, we have experienced problems achieving acceptable yields at our third-party wafer fabrication partners, resulting in delays in the availability of components. Moreover, an increase in the rejection rate of products during the quality control process before, during or after manufacture and/or shipping of such products, results in lower yields and margins. In addition, changes in manufacturing processes required as a result of changes in product specifications, changing customer needs and the introduction of new product lines have historically significantly reduced our manufacturing yields, resulting in low or negative margins on those products. Poor manufacturing yields over a prolonged period of time could adversely affect our ability to deliver our products on a timely basis and harm our relationships with customers, which could materially and adversely affect our business, financial condition and results of operations.

In the event of a disruption at one of our primary third-party wafer fabrication facilities, we may be required to transition our manufacturing capabilities to another facility, which could impact production efficiency and our ability to meet our customers’ needs.

Our reliance on a limited number of third-party wafer fabrication facilities, primarily PSL, United Microelectronics Corporation (“UMC”) and Taiwan Semiconductor Manufacturing Company (“TSMC”), for the fabrication of semiconductor wafers used in the manufacture of our IC products means that any disruption in their supply of wafers (including ceasing or suspending operations entirely), may require us to transfer manufacturing processes to a new location or facility. Significant disruptions in our third-party wafer fabrication facilities could occur as a result of a number of events, including, for example, the recent COVID-19 pandemic and certain natural disasters, such as earthquakes, which are commonplace in Taiwan (where both UMC and TSMC are located). Converting or transferring such fabrication processes from one of our primary facilities to an alternative or backup facility due to a disruption would likely be expensive and could take substantial time, given our highly complex manufacturing and fabrication processes, which incorporate our proprietary technologies. During such a transition, we may attempt to meet customer demand through our existing inventories, or may attempt to modify partially finished goods to meet the required fabrication specifications. Given the rapid obsolescence timeline to which our products are typically subject, however, we generally do not maintain significant levels of excess inventory and, as a result, it is unlikely that our existing inventory will be sufficient to meet customer demand during such a transition. In addition, any attempt to modify partially finished goods to meet the required fabrication specifications may not be successful and will require us to incur unanticipated costs. As a result, we may not be able to meet our customers’ needs during such a transition, which would negatively impact our net sales, potentially damage our customer relationships and our reputation and may have a material adverse effect on our business, financial condition and results of operations.

We have in the past and may in the future implement initiatives designed to improve our competitiveness, growth and profitability. We may fail to realize the full benefits of, and could incur significant costs relating to, any such initiatives, which could materially and adversely affect our business, financial condition and results of operations.

Beginning in 2016, we began a multi-year strategic transition to extend our market leadership through targeted product portfolio expansion; to improve our operating model through a more nimble, fabless and asset-

32

lite manufacturing strategy; to increase our IC design footprint and capacity; and to accelerate growth through enhanced sales operations. In connection with this transition, we have recently implemented a number of initiatives designed to improve our operating results. For example, subsequent to the end of fiscal year 2020, in order to further our strategy for developing a flexible and efficient manufacturing model that minimizes capital requirements, lowers operating costs, enhances reliability of supply and supports our growth going forward, we consummated the PSL Divestiture, transferred our Sanken products distribution business to PSL, and entered into certain other agreements and transactions with PSL, in each case, as more fully described elsewhere in this prospectus under “Prospectus Summary—The Divestiture Transactions,” In addition, in February 2020, we announced that we would consolidate our assembly and test facilities into a single site located at the AMPI Facility.

We continue to evaluate opportunities to reduce our manufacturing cost and may implement additional initiatives designed to improve our gross margin and operating results and may perform future restructurings. We cannot assure you that we will realize the cost savings and productivity improvements we expect as a result of these or any future restructuring and cost improvement initiatives. These efforts involve a significant investment of financial and human resources and significant changes to our operating processes. Future initiatives to transfer or consolidate manufacturing operations could also involve significant start-up or qualification costs for new or repurposed facilities. The failure to realize the full benefits of, or the incurrence of significant costs relating to, these or other restructuring initiatives could materially and adversely affect our business, financial condition and results of operations.

Our quarterly net sales and operating results are difficult to predict accurately and may fluctuate significantly from period to period. As a result, we may fail to meet the expectations of investors, which could cause our stock price to decline.

We operate in a highly dynamic industry and our future operating results could be subject to significant fluctuations, particularly on a quarterly basis. Our quarterly net sales and operating results have fluctuated significantly in the past and may continue to vary from quarter to quarter due to a number of factors, many of which are not within our control. Although some of our customers, for example those in the automotive industry, provide us with forecasts of their future requirements for our products, a significant percentage of our net sales in each fiscal quarter is dependent on sales that are booked and shipped during that fiscal quarter, and are typically attributable to a large number of orders from diverse customers and markets. As a result, accurately forecasting our operating results in any fiscal quarter is difficult. If our operating results do not meet the expectations of securities analysts and investors, our stock price may decline. Additional factors that can contribute to fluctuations in our operating results include:

33

We may experience a delay in generating or recognizing revenues for a number of reasons. Open orders at the beginning of each quarter are typically lower than expected net sales for that quarter and are generally cancelable or reschedulable with minimal notice. Accordingly, we depend on obtaining orders during each quarter for shipment in that quarter to achieve our net sales objectives and failure to fulfill such orders by the end of a quarter may adversely affect our operating results. Furthermore, our customer agreements typically provide that the customer may delay scheduled delivery dates and cancel orders within specified timeframes without significant penalty. In addition, we maintain an infrastructure of facilities and human resources in several locations around the world and have a limited ability to reduce the expenses required to maintain such infrastructure. Because we base our operating expenses on anticipated revenue trends and a high percentage of our expenses are fixed in the short term, any delay in generating or recognizing forecasted net sales or changes in levels of our customers’ forecasted demand could materially and adversely impact our business, financial condition and results of operations. Due to our limited ability to reduce expenses, in the event our revenues decline or our forecasted net sales do not meet our expectations, it is likely that in some future quarters our

34

operating results will decrease from the previous quarter or fall below the expectations of securities analysts and investors. As a result of these factors, our operating results may vary significantly from quarter to quarter. Accordingly, we believe that period-to-period comparisons of our results of operations should not solely be relied upon as indications of future performance. Any shortfall in net sales or net income from a previous quarter or from levels expected by the investment community could cause a decline in the trading price of our stock.

Failure to adjust our supply chain volume due to changing market conditions or failure to estimate our customers’ demand could adversely affect our net sales and could result in additional charges for obsolete or excess inventories or non-cancelable purchase commitments.

We make significant decisions, including determining the levels of business that we will seek and accept, production schedules, levels of reliance on outsourced contract manufacturing, personnel needs and other resource requirements, based on our estimates of customer requirements. The short-term nature of the commitments by many of our customers and the possibility of rapid changes in demand for their products reduces our ability to accurately estimate future requirements of our customers. On occasion, our customers may require rapid increases in production, which can challenge our resources. We may not have sufficient capacity at any given time to meet our customers’ demands. Conversely, downturns in the semiconductor industry have in the past caused and may in the future cause our customers to significantly reduce the amount of products ordered from us. Because many of our sales, research and development, and manufacturing expenses are relatively fixed, a reduction in customer demand may decrease our gross margins and operating income.

In addition, we base many of our operating decisions, and enter into purchase commitments, on the basis of anticipated net sales trends which are highly unpredictable. Some of our purchase commitments are not cancelable, and in some cases we are required to recognize a charge representing the amount of material or capital equipment purchased or ordered which exceeds our actual requirements. For example, we have non-cancelable purchase commitments with vendors and “take-or-pay” agreements with certain of our third-party wafer fabrication partners, under which we are required to purchase a minimum number of wafers per year or face financial penalties. These types of commitments and agreements could reduce our ability to adjust our inventory to address declining market demands. If demand for our products is less than we expect, we may experience additional excess and obsolete inventories and be forced to incur additional charges. If net sales in future periods fall substantially below our expectations, or if we fail to accurately forecast changes in demand mix, we could again be required to record substantial charges for obsolete or excess inventories or non-cancelable purchase commitments.

Moreover, during a market upturn, we may not be able to purchase sufficient supplies or components to meet increasing product demand, which could prevent us from taking advantage of opportunities and reduce our net sales. In addition, a supplier could discontinue a component necessary for our design, extend lead times, limit supply or increase prices due to capacity constraints or other factors. Our failure to adjust our supply chain volume or estimate our customers’ demands could have a material adverse effect on our net sales, business, financial condition and results of operations.

We rely on a limited number of third-party wafer fabrication facilities for the fabrication of semiconductor wafers and on a limited number of suppliers of other materials, and the failure of any of these suppliers or additional suppliers to continue to produce wafers or other materials on a timely basis could harm our business and our financial results.

We currently rely on a limited number of third-party wafer fabrication facilities for the fabrication of semiconductor wafers used in the manufacture of our IC products and we purchase a number of key materials and components used in the manufacture of our products from single or limited sources. We depend on these foundries and other sources to meet our production needs. Moreover, we depend on the quality of the wafers and other components and materials that they supply to us, over which we have limited control. Any one or more of our other suppliers may become financially unstable as the result of global market conditions. Moreover, our

35

suppliers’ abilities to meet our requirements could be impaired or interrupted by factors beyond their control, such as natural disasters or other disruptions. In addition, from time to time we have encountered shortages and delays in obtaining wafers and other components and materials, and we may encounter additional shortages and delays in the future. If we cannot supply our products due to a lack of components or are unable to source materials from other suppliers or to redesign products with other components in a timely manner, our business will be significantly harmed. We do not have long-term contracts with some of our suppliers and third-party manufacturers. As a result, any such supplier or third-party manufacturer can discontinue supplying components or materials to us at any time and without penalty. In the event that any one or more of our suppliers is unable or unwilling to deliver us products and we are unable to identify alternative sources of supply for such materials or components on a timely basis, our operations may be adversely affected. In addition, even if we identify any such alternative sources of supply, we could experience delays in testing, evaluating and validating materials or products of potential alternative suppliers or products we obtain through outsourcing. Qualifying new contract manufacturers, and specifically semiconductor foundries, is time consuming and might result in unforeseen manufacturing and operations problems. Furthermore, financial or other difficulties faced by our suppliers, or significant changes in demand for the components or materials they use in the products they supply to us, could limit the availability of those products, components or materials to us. We are also subject to potential delays in the development by our suppliers of key components which may affect our ability to introduce new products. Any of these problems or delays could damage our relationships with our customers, adversely affect our reputation and adversely affect our business, financial condition, results of operations and our ability to grow our business.

Our dependence on our manufacturing operations in the Philippines exposes us to certain risks that may harm our business.

We rely heavily on the manufacturing operations of the AMPI Facility, which operates as our primary internal assembly and testing facility. We depend primarily on the AMPI Facility for our sensor and power products and, if this facility suspends operations, our ability to assemble and test our products could be materially impaired. Furthermore, any disruption in operations at the AMPI Facility could adversely affect our ability to meet customer demand in a timely manner, or at all, which would to lead to a reduction in our net sales and may adversely affect our reputation and customer relationships, potentially resulting in longer-term harm to our business. In addition, an earthquake, fire, flood or other natural or manmade disaster, as well as a pandemic, epidemic or other outbreak of infectious disease, including the current COVID-19 pandemic, strikes, political or civil unrest, or any number of other factors beyond our control could also disable such facility, causing catastrophic losses. Although we supplement the assembly capabilities at the AMPI Facility with the operations of AMTC Facility and several other external or independent assembly subcontractors throughout Asia, if our manufacturing operations at the AMPI Facility are obstructed or hampered, it could take a considerable length of time, at an increased cost, for us to resume manufacturing at another location, which could materially harm our manufacturing efficiency and capacity, delay production and shipments and result in costly expenditures to repair or replace this facility. Moreover, while we currently maintain manufacturing operations at the AMTC Facility, we have commenced the closure of such facility, with the intention to sell such facility by the end of March 2021 as part of our manufacturing footprint optimization strategy, which will heighten our dependence on the AMPI Facility in the future. As a result, any such losses could materially and adversely affect our business, financial condition, results of operations, cash flows and prospects.

To ensure continued product manufacturing (including assembly and testing of our products), we may be required to establish or invest in alternative manufacturing facilities. Any attempt to establish or invest in alternative manufacturing facilities, however, could increase our costs, negatively affect our profitability, and limit our ability to maintain competitive prices for our products, which would negatively impact our competitive position. While we rely on the AMPI Facility as our primary manufacturing facility for our select sensor and power products, we are aware that only a few alternative manufacturing facilities have the capability to assemble and test our most advanced and complex products and if we are forced to engage such alternative manufacturing facilities, we may encounter difficulties and incur additional costs.

36

Accordingly, we cannot guarantee that we will be able to manage the risks and challenges associated with our dependence on the AMPI Facility, and any failure to do so could have a material adverse effect on our business, financial condition and results of operations.

A significant portion of our net sales are generated through distributors, which subjects us to certain risks.

We sell our products worldwide through multiple sales channels, including through our direct sales force, distributors and independent sales representatives, which resell our products to numerous end customers. A significant portion of our net sales are made to distributors, accounting for approximately 27.4% and 25.2% of our net sales in fiscal years 2019 and 2020, respectively, and approximately 23.4% and 40.1% of our net sales in the three-month periods ended June 28, 2019 and June 26, 2020, respectively, excluding our distribution relationship with Sanken in Japan, which represented approximately 16.8% and 17.3% of our net sales in fiscal years 2019 and 2020 and approximately 17.9% and 20.5% of our net sales in the three-month periods ended June 28, 2019 and June 26, 2020. The impairment or termination of our relationships with our distributors, or the failure of these parties to diligently sell our products and comply with applicable laws and regulations, could materially and adversely affect our ability to generate revenue and profits. Because our distributors control the relationships with end customers, if our relationship with any distributor ends, we could also lose our relationships with their customers. Furthermore, our success is partially dependent on the willingness and ability of the sales representatives and other employees of our distributors to diligently sell our products. However, we cannot guarantee that they will be successful in marketing our products. In addition, because our distributors do not sell our products exclusively, they may focus their sales efforts and resources on other products that produce better margins or greater commissions for them or are incorporated into a broader strategic relationship with one of their other suppliers. Because we do not control the sales representatives and other employees of our distributors, we cannot guarantee that our sales processes, regulatory compliance and other priorities will be consistently communicated and executed. In addition, we may not have staff in one or more of the locations covered by our distributors, which makes it particularly difficult for us to monitor their performance. While we may take steps to mitigate the risks associated with noncompliance by our distributors, there remains a risk that they will not comply with regulatory requirements or our requirements and policies. Actions by the sales representatives and other employees of our distributors that are beyond our control could result in flat or declining sales in a given geographic area, harm to the reputation of our company or our products, or legal liability, any of which could have a material adverse effect on our business, financial condition and results of operations. In addition to the risk of losing customers, the operation of local laws and our agreements with our distributors could make it difficult for us to replace a distributor we feel is underperforming. In addition, as discussed above, our distribution relationship with Sanken in Japan has historically accounted for a significant portion of our total net sales. Though we believe we would be able to establish relationships with new distributors or otherwise increase the business we do with our existing distributors if our distribution relationship with Sanken were to become impaired, we cannot guarantee we would be able to do so on a timely basis or at all, or that we would be able to realize a similar level of net sales as under our current arrangements.

Events beyond our control could have an adverse effect on our business, financial condition, results of operations and cash flows.

Our ability to make, transport and sell products in coordination with our suppliers, customers (including OEMs), distributors and third-party manufacturers or other subcontractors is critical to our success. Damage or disruption to our supply, manufacturing or distribution capabilities resulting from weather, freight carrier availability, any potential effects of climate change, natural disaster, disease, fire, explosion, cyber-attacks, terrorism, pandemics, epidemics or other outbreaks of infectious disease, strikes, civil unrest, repairs or enhancements at facilities manufacturing or distribution of our products or other reasons could impair our ability to manufacture, sell our products, and to deliver products to our customers on a timely basis or at all.

Similarly, disruptions in the operations of our key suppliers or in the services provided by our third-party wafer fabrication partners or other contract manufacturers, including disruptions due to natural disasters or other

37

disruptions, or by the transition by us to other suppliers or third-party manufacturers could lead also to supply chain problems and otherwise impair or delay our ability to deliver products to our customers on a timely basis or at all.

Other companies in our industry may be affected differently by natural disasters or other disruptions depending on the location of their suppliers, operations and customers. In addition, many of our competitors are larger companies with more substantial financial and other resources and, as a result, may be better able to plan for, withstand or otherwise mitigate the effects of any such disruption. While we may take steps to plan for or address the occurrence of any such event, we cannot guarantee that we will be successful. If we fail to take adequate steps to reduce the likelihood or mitigate the potential impact of such events, or to effectively manage such events if they occur, particularly when an wafer or packaging component is sourced from a limited number of locations or suppliers, could adversely affect our business, financial condition, results of operations and cash flows and/or require additional resources to restore our supply chain.

Our business, financial condition, results of operations, liquidity and prospects have been, and may continue to be, adversely affected by health epidemics, pandemics and other outbreaks of infectious disease, including the current COVID-19 pandemic.

Public health threats, such as COVID-19, influenza and other highly communicable diseases or viruses, outbreaks of which have from time to time occurred in various parts of the world in which we operate could adversely impact our operations, as well as the operations of our customers, end users of our products, and our and their respective vendors, suppliers and other business partners. Any of these public health threats and related consequences could adversely affect our financial results.

COVID-19, a potentially deadly respiratory tract infection caused by the SARS-CoV-2 virus, has spread rapidly and enveloped most of the world, causing a global public health crisis. On March 11, 2020, the COVID-19 outbreak was declared a pandemic by the World Health Organization. The pandemic has resulted in national and local governments in affected countries around the world implementing increasingly stringent measures to help control the spread of the virus, including quarantines and other emergency public health measures and have implemented substantial lockdown measures, and additional countries and local governments may enact similar policies. In addition, the federal government and all of the states in the United States, have declared a state of emergency or similar disaster declaration, and many states and other jurisdictions where we have operations have implemented “shelter in place” and “stay-at-home” orders, workplace closures, business curtailments and other similar measures. The measures implemented by various authorities in response to the COVID-19 pandemic have caused us to change our business practices, including those related to where employees work, the distance between employees in the our facilities, limitations on in-person meetings between employees and with customers, suppliers, service providers and stakeholders, as well as restrictions on business travel to domestic and international locations and to attend trade shows, investor conferences and other events. These restrictions have had, and future prevention and mitigation measures are also likely to have, an adverse impact on global economic conditions, which could further affect our operations. The considerable uncertainty regarding the economic impact of the COVID-19 pandemic are likely to result in sustained market turmoil, which could also negatively impact our business, financial condition and cash flows.

These current and potential future measures that could restrict access to our facilities, limit manufacturing and support operations and place restrictions on our workforce, suppliers and other business partners have impacted and may further impact our workforce and operations, the operations of our customers and end users of our products, and those of our respective vendors, suppliers and other business partners. The disruptions to our operations caused by the COVID-19 pandemic may result in inefficiencies, delays and additional costs in our product development, sales, marketing, and customer service efforts that we cannot fully mitigate through remote or other alternative work arrangements. In addition, the severe global economic disruption, including recession, depression or other sustained adverse market impact caused by the COVID-19 pandemic, may cause our customers and end-users of our products to suffer significant economic hardship and potentially even go out of

38

business, which could result in decreased demand for our products and materially and adversely affect our business, results of operations, financial condition, including liquidity and prospects. To the extent that the COVID-19 pandemic adversely affects our business, financial condition, results of operations or liquidity, it may also heighten many of the other risks discussed in this prospectus. For instance, if the business impacts of COVID-19 continue for an extended period, this could cause us to recognize impairments for goodwill and certain long-lived assets including amortizable intangible assets.

The impact of the COVID-19 pandemic continues to evolve and its duration and ultimate disruption to our business and the businesses of our customers and end-users, the overall demand for our products, our supply chain, and the related financial impact to us, as well as any similar disruptions that may result from any future pandemic, epidemic or other outbreak of infectious disease, will depend on future developments, which are highly uncertain and cannot be predicted, including, but not limited to, the duration and spread of the pandemic, its severity, the effectiveness of actions to contain the virus or treat its impact and how quickly and to what extent normal economic and operating conditions can resume, among others. The longer any such disruption continues, however, the more severe and adverse we would expect the effect to be on our business, financial condition, results of operations and liquidity. Even after the COVID-19 pandemic has lessened or subsided, we may continue to experience adverse impacts on our business, financial condition and results of operations as a result of its global economic impact. As new information regarding COVID-19 continues to emerge, it is difficult to predict the full extent to which the disease adversely impacts our financial performance. Additionally, weaker economic conditions generally could result in impairment in value of our tangible or intangible assets and our ability to raise additional capital, if needed.

Our indebtedness may limit our flexibility to operate our business and adversely affect our financial health and competitive position.

As of June 26, 2020, we had $33.0 million in aggregate principal amount of debt outstanding, which consisted of $25.0 million of debt outstanding under the AML Revolver and $8.0 million of debt outstanding under the AML Line of Credit. After giving effect to our entry into the Senior Secured Credit Facilities, our incurrence of $325.0 million in aggregate principal amount of debt under the Term Loan Facility in connection with the Recapitalization, and the consummation of the Refinancing, we would have had $325.0 million in aggregate principal amount of debt outstanding as of such date, and $50.0 million of additional borrowings available under the Revolving Credit Facility. Following the consummation of this offering, after giving effect to our use approximately $244.0 million of the net proceeds to be received by us from this offering to repay borrowings under the Term Loan Facility, we expect the amount of debt outstanding under the Term Loan Facility will be $81.0 million. In order to service this indebtedness, and any additional indebtedness or other long-term obligations we may incur in the future, we need to generate sufficient levels of cash from our operating activities. Our ability to generate cash is subject, in part, to our ability to successfully execute our business strategy, as well as general economic, financial, competitive, regulatory and other factors beyond our control. We cannot assure you that our business will be able to generate sufficient levels of cash from operations or that future borrowings or other financings will be available to us in an amount sufficient to enable us to service our indebtedness and fund our other liquidity needs. To the extent we are required to use cash from operations or the proceeds of any future financing to service our indebtedness instead of funding working capital, capital expenditures or other general corporate purposes, we will be less able to plan for, or react to, changes in our business, industry and in the economy generally. This will place us at a competitive disadvantage compared to our competitors that have less indebtedness.

In addition, the agreements governing the Senior Secured Credit Facilities contain, and any agreements evidencing or governing other future indebtedness may also contain, certain covenants that limit our and our restricted subsidiaries’ ability to engage in certain transactions that may be in our long-term best interests. Subject to certain limited exceptions, these covenants limit our and our restricted subsidiaries’ ability to, among other things:

39

Our ability to comply with these covenants may be affected by events and factors beyond our control. In the event that we breach one or more covenants, our lenders may choose to declare an event of default and require that we immediately repay all amounts outstanding, terminate any commitment to extend further credit and foreclose on any collateral granted to them to secure such indebtedness. The occurrence of any of these events could have a material adverse effect on our business, financial condition and results of operations.

In addition, we may be able to incur significant additional indebtedness in the future. While the agreements governing our Senior Secured Credit Facilities generally restrict our and our restricted subsidiaries’ ability to incur additional indebtedness, these restrictions are subject to important and significant exceptions and limitations. Also, these agreements generally do not prohibit us from incurring obligations that do not constitute indebtedness as defined therein. To the extent that we incur additional indebtedness or such other obligations, the risks associated with our indebtedness described above will increase.

Uncertainty relating to the LIBOR calculation process and potential phasing out of LIBOR after 2021 may adversely affect the market value of our current or future debt obligations.

The London Inter-bank Offered Rate (“LIBOR”) and certain other interest “benchmarks” may be subject to regulatory guidance and/or reform that could cause interest rates under our current or future debt agreements to perform differently than in the past or cause other unanticipated consequences. The United Kingdom’s Financial Conduct Authority, which regulates LIBOR, has announced that it intends to stop encouraging or requiring banks to submit LIBOR rates after 2021, and it is unclear if LIBOR will cease to exist or if new methods of calculating LIBOR will evolve. If LIBOR ceases to exist or if the methods of calculating LIBOR change from their current form, there may be adverse impacts on the financial markets generally and interest rates on borrowings under our Senior Secured Credit Facilities may be adversely affected.

We depend on growth in the end markets that use our products. Any slowdown in the growth of these end markets could adversely affect our financial results.

Our continued success will depend in large part on general economic growth and growth within our target markets in the automotive and industrial sectors. Factors affecting these markets could seriously harm our customers and, as a result, harm us, including:

40

Any slowdown in the growth of these end markets could adversely affect our financial results. For example, a significant element of our growth strategy depends on the increasing adoption of mild hybrid, hybrid and electric vehicles, which are expected to have higher sensor and power product content. If anticipated demand in the end market for these vehicles does not materialize, it would adversely affect demand for our products from customers and impact our ability to execute our growth strategy.

The loss of one or more significant end customers could have a material adverse effect on our business and results of operations.

We believe no end customer, including those served through our distributors, exceeded 10% of our net sales during either fiscal year. However, the loss of or a significant reduction in business with a significant end customer, particularly in the automotive market, could have a material adverse effect on our net sales and, in turn, on our overall business, financial condition and results of operations.

If we fail in a timely and cost-effective manner to develop new product features or new products that address customer preferences and achieve market acceptance, our operating results could be adversely affected.

Our customers are constantly seeking new products with more features and functionality at a lower cost, and our success relies heavily on our ability to continue to develop and market to our customers new and innovative products and improvements of existing products. In order to respond to new and evolving customer demands, achieve strong market share and keep pace with new technological, processing and other developments, we must constantly introduce new and innovative products into the market. Although we strive to respond to customer preferences and industry expectations in the development of our products, we may not be successful in developing, introducing or commercializing any new or enhanced products on a timely basis or at all. Further, if initial sales volumes for new or enhanced products do not reach anticipated levels within the time periods we expect, we may be required to engage in additional marketing efforts to promote such products and the costs of developing and commercializing such products may be higher than we predict. Moreover, new and enhanced products may not perform as expected. We may also encounter lower manufacturing yields and longer delivery schedules in commencing volume production of new products that we introduce, which could increase our costs and disrupt our supply of such products.

A fundamental shift in technologies, the regulatory climate or demand patterns and preferences in our existing product markets or the product markets of our customers or end-users could make our current products obsolete, prevent or delay the introduction of new products or enhancements to our existing products or render our products irrelevant to our customers’ needs. If our new product development efforts fail to align with the

41

needs of our customers, including due to circumstances outside of our control like a fundamental shift in the product markets of our customers and end users or regulatory changes, our business, financial condition and results of operations could be materially and adversely affected.

Our competitive position could be adversely affected if we are unable to meet customers’ quality requirements.

Semiconductor IC suppliers must meet increasingly stringent quality standards of certain OEMs and customers, particularly for automotive applications. While our quality performance to date has generally met these requirements, we may experience problems in achieving acceptable quality results in the manufacture of our products, particularly in connection with the production of new products or adoption of a new manufacturing process. Our failure to achieve acceptable quality levels could adversely affect our business results.

The nature of the design win process requires us to incur expenses without any guarantee that research and development efforts will generate net sales, which could adversely affect our financial results.

We focus on winning competitive bid selection processes, called “design wins,” to develop products for use in our customers’ products. These lengthy selection processes may require us to incur significant expenditures and dedicate valued engineering resources to the development of new products without any assurance that we will achieve design wins. If we incur such expenditures and fail to be selected in the bid selection process, our operating results may be adversely affected. Further, because of the significant costs associated with qualifying new suppliers, customers are likely to use the same or an enhanced version of semiconductor products from existing suppliers across a number of similar and successor products for a lengthy period of time. As a result, if we fail to secure an initial design win for any of our products to any particular customer, we may lose the opportunity to make future sales of those products to that customer for a significant period of time or at all and experience an associated decline in net sales relating to those products. This phenomenon is typical in the automotive market. Failure to achieve initial design wins may also weaken our position in future competitive selection processes because we may not be perceived as an industry leader.

Even if we succeed in securing design wins for our products, we may not generate timely or sufficient net sales or margins from those wins and our financial results could suffer.

After incurring significant design and development expenditures and dedicating engineering resources to achieve a single initial design win for a product, a substantial period of time generally elapses before we generate meaningful net sales relating to such product, if at all. The reasons for this delay include, among other things, the following:

If we do not continue to achieve design wins in the short term, then we may not be able to achieve expected net sales levels associated with these design wins. If we experience delays in achieving such sales levels, our operating results could be adversely affected. Moreover, even if a customer selects our product, we cannot guarantee that this will result in any sales of our products, as the customer may ultimately change or cancel its product plans, or our customer’s efforts to market and sell its product may not be successful.

42

Changes in government trade policies, including the imposition of tariffs and export restrictions, could limit our ability to sell our products to certain customers or demand from certain customers, which may materially and adversely affect our sales and results of operations.

The current U.S. President, members of his administration, and other public officials, including members of the current U.S. Congress, have made public statements indicating possible significant changes in U.S. trade policy and have taken certain actions that may impact U.S. trade policy, including imposing new or increased tariffs on certain goods imported into the United States. Since we manufacture our products outside the United States, such changes, if adopted, could have a disproportionate impact on our business and make our products more expensive and less competitive in domestic markets. Furthermore, changes in U.S. trade policy could trigger retaliatory actions by affected countries, which could impose restrictions on our ability to do business in or with affected countries or prohibit, reduce or discourage purchases of our products by foreign customers, leading to increased costs of components contained in our products, increased costs of manufacturing our products, and higher prices for our products in foreign markets. For example, there are risks that the Chinese government may, among other things, require the use of local suppliers in place of non-Chinese suppliers like us, compel companies that do business in China to partner with local companies to conduct business and provide incentives to government-backed local customers to buy from local suppliers. Changes in, and responses to, U.S. trade policy could reduce the competitiveness of our products and cause our sales to decline, which could materially and adversely impact our business, financial condition and results of operations.

The U.S. or foreign governments may take administrative, legislative or regulatory action that could materially interfere with our ability to sell products in certain countries and/or to certain customers, particularly in China. For example, the United States and China have imposed a number of tariffs and other restrictions on items imported or exported between the United States and China, and have proposed to impose a number of additional tariffs. We cannot predict what actions may ultimately be taken with respect to tariffs or trade relations between the United States and China or other countries, what products may be subject to such actions, or what actions may be taken by the other countries in retaliation. The institution of trade tariffs both globally and between the United States and China specifically carries the risk of negatively impacting China’s overall economic condition, which could have negative repercussions for our business.

Warranty claims, product liability claims and product recalls could harm our business, results of operations and financial condition.

We face an inherent business risk of exposure to warranty and product liability claims if products fail to perform as expected or is alleged to result in bodily injury, death, and/or property damage. In addition, if any of our designed products are alleged to be defective, we may be required to participate in their recall. Some OEMs expect suppliers to warrant their products for longer periods of time and are increasingly looking to them for contribution when faced with product liability claims or recalls. For example, some of our products are used in automotive safety systems, the failure of which could lead to injury or death. We carry various commercial liability policies, including umbrella/excess policies which provide some protection against product liability exposure. However, a successful warranty or product liability claim against us in excess of our available insurance coverage and established reserves, or a requirement that we participate in a product recall, could have adverse effects on our business results. Further, in the future it is possible that we will not be able to obtain insurance coverage in the amounts and for the risks we seek at policy costs and terms we desire.

Additionally, in the event that our products fail to perform as expected or such failure of our products results in a recall, our reputation may be damaged, which could make it more difficult for us to sell our products to existing and prospective customers and could materially and adversely affect our business, results of operations and financial condition.

43

If we are unable to protect our proprietary technology and inventions through patents, our ability to compete successfully and our financial results could be adversely impacted.

We seek to protect our proprietary technology and inventions, particularly those relating to the design of our products, through the use of patents. As of August 31, 2020, we owned 1,019 patents, including 542 active U.S. patents (with expiration dates between 2020 and 2039), with an additional 414 pending patent applications, including 171 U.S. patent applications. Maintenance of patent portfolios, particularly outside of the U.S., is expensive, and the process of seeking patent protection is lengthy and costly. While we intend to maintain our current portfolio of patents and to continue to prosecute our currently pending patent applications and file future patent applications when appropriate, the value of these actions may not exceed their expense. Existing patents and those that may be issued from any pending or future applications may be subject to challenges, invalidation or circumvention, and the rights granted under our patents may not provide us with meaningful protection or any commercial advantage. In addition, the protection afforded under the patent laws of one country may not be the same as that in other countries. This means, for example, that our right to exclusively commercialize a product in those countries where we have patent rights for that product can vary on a country-by-country basis. We also may not have the same scope of patent protection in every country where we do business.

Additionally, it is difficult and costly to monitor the use of our intellectual property. It may be the case that our intellectual property is already being infringed and infringement may occur in the future without our knowledge. The difficulty and failure to identify any violations of our intellectual property rights could materially and adversely affect our business, financial condition and result of operations and hurt our competitive advantage.

If we are unable to protect our proprietary technology and inventions through trade secrets, our competitive position and financial results could be adversely affected.

We seek to protect our proprietary technology and inventions, particularly those relating to our manufacturing processes, as trade secrets. In the United States, trade secrets are protected under the federal Economic Espionage Act of 1996 and the Defend Trade Secrets Act of 2016 (the “Defend Trade Secrets Act”), and under state law, with many states having adopted the Uniform Trade Secrets Act (the “UTSA”) and several of which that have not. In addition to these federal and state laws inside the United States, under the World Trade Organization’s Trade Related-Aspects of Intellectual Property Rights Agreement, trade secrets are to be protected by World Trade Organization member states as “confidential information.” Under the UTSA and other trade secret laws, protection of our proprietary information as trade secrets requires us to take steps to prevent unauthorized disclosure to third parties or misappropriation by third parties. In addition, the full benefit of the remedies available under the Defend Trade Secrets Act requires specific language and notice requirements present in the relevant agreements, which may not be present in all of our agreements. While we require our officers, employees, consultants, distributors, and existing and prospective customers and collaborators to sign confidentiality agreements and take various security measures to protect unauthorized disclosure and misappropriation of our trade secrets, we cannot assure or predict that these measures will be sufficient. The semiconductor industry is generally subject to high turnover of employees, so the risk of trade secret misappropriation may be amplified. If any of our trade secrets are subject to unauthorized disclosure or are otherwise misappropriated by third parties, our competitive position may be materially and adversely affected.

Our ability to compete successfully depends in part on our ability to commercialize our products without infringing the patent, trade secret or other intellectual property rights of others.

To the same extent that we seek to protect our technology and inventions with patents and trade secrets, our competitors and other third parties do the same for their technology and inventions. We have no means of knowing the content of patent applications filed by third parties until they are published. It is also difficult and costly to continuously monitor the intellectual property portfolios of our competitors to ensure our technologies do not violate the intellectual property rights of any third parties.

44

The semiconductor industry is ripe with patent assertion entities and is characterized by frequent litigation regarding patent and other intellectual property rights. From time to time, we receive communications from third parties that allege that our products or technologies infringe their patent or other intellectual property rights. As a public company with an increased profile and visibility, we may receive similar communications in the future. Lawsuits or other proceedings resulting from allegations of infringement could subject us to significant liability for damages, invalidate our proprietary rights and adversely affect our business. In the event that any third-party succeeds in asserting a valid claim against us or any of our customers, we could be forced to do one or more of the following:

If a third-party causes us to discontinue the use of any of our technologies, we could be required to design around those technologies. This could be costly and time consuming and could have an adverse effect on our financial results. Any significant impairments of our intellectual property rights from any litigation we face could materially and adversely impact our business, financial condition, results of operations and our ability to compete in our industry.

We may be subject to disruptions or breaches of our information technology systems that could irreparably damage our reputation and our business, expose us to liability and materially and adversely affect our results of operations.

We are subject to a number of legal requirements, contractual obligations and industry standards regarding security, data protection and privacy and any failure to comply with these requirements, obligations or standards could have an adverse effect on our reputation, business, financial condition and operating results.

In conducting our business, we routinely collect and store sensitive data, including proprietary technology and information about our business and our customers, suppliers and business partners, including proprietary technology and information owned by our customers. The secure processing, maintenance and transmission of this information is critical to our operations and business strategy. We may be subject to disruptions or breaches of our secured network caused by computer viruses, illegal hacking, criminal fraud or impersonation, acts of vandalism or terrorism or employee error. Our security measures, those of our third-party service providers, or our customers may not detect or prevent such security breaches. The costs to us to reduce the risk of or alleviate cyber security breaches and vulnerabilities could be significant. Any type of security breach, attack or misuse of data, whether experienced by us or an associated third party, could harm our reputation or deter existing or prospective customers from using our products and applications, increase our operating expenses in order to contain and remediate the incident, expose us to unbudgeted or uninsured liability, disrupt our operations, divert management focus away from other priorities, increase our risk of regulatory scrutiny, result in the imposition of penalties and fines under state, federal and foreign laws or by payment networks and adversely affect our continued payment network registration and financial institution sponsorship. Moreover, any such compromise of our information security could result in the misappropriation or unauthorized publication of our confidential business or proprietary information or that of other parties with which we do business, an interruption in our operations, the unauthorized transfer of cash or other of our assets, the unauthorized release of customer or employee data or a violation of privacy or other laws. In addition, computer programmers and hackers also may

45

be able to develop and deploy viruses, worms and other malicious software programs that attack our products, or that otherwise exploit any security vulnerabilities, and any such attack, if successful, could expose us to liability to customer claims. Any of the foregoing could irreparably damage our reputation and business, which could have a material adverse effect on our results of operations.

We are subject to governmental regulation and other legal obligations, particularly related to privacy, data protection and information security, and consumer protection laws across different markets where we conduct our business. Our actual or perceived failure to comply with such obligations could harm our business.

In the United States and other jurisdictions in which we operate, we are subject to various consumer protection laws and related regulations. If we are found to have breached any consumer protection laws or regulations in any such jurisdiction, we may be subject to enforcement actions that require us to change our business practices in a manner which may negatively impact our revenue, as well as expose us to litigation, fines, civil and/or criminal penalties and adverse publicity that could cause our customers to lose trust in us, negatively impacting our reputation and business in a manner that harms our financial position.

As part of our business, we collect information about individuals, also referred to as personal data, and other potentially sensitive and/or regulated data from our customers. Laws and regulations in the United States and around the world restrict how personal information is collected, processed, stored, used and disclosed, as well as set standards for its security, implement notice requirements regarding privacy practices, and provide individuals with certain rights regarding the use, disclosure and sale of their protected personal information.

In the United States, both the federal and various state governments have adopted or are considering, laws, guidelines or rules for the collection, distribution, use and storage of information collected from or about consumers or their devices. For example, California enacted the California Consumer Privacy Act requires, among other things, new disclosures to California consumers, imposes new rules for collecting or using information about minors, and afford consumers new abilities to opt out of certain disclosures of personal information.

Several foreign jurisdictions, including the European Union (“EU”), have laws and regulations which are more restrictive in certain respects than those in the United States. For example, the EU General Data Protection Regulation (“GDPR”) implemented stringent operational requirements for the use of personal data. The European regulatory regime also includes laws which, among other things, require EU member states to regulate marketing by electronic means and the use of web cookies. Each EU member state has transposed the requirements of these laws into its own national data privacy regime, and therefore the laws may differ between jurisdictions.

The GDPR introduced more stringent requirements (which will continue to be interpreted through guidance and decisions over the coming years) and require organizations to erase an individual’s information upon request, implement mandatory data breach notification requirements and additional new obligations on data processors. If our privacy or data security measures fail to comply with applicable current or future laws and regulations, we may be subject to litigation, regulatory investigations, enforcement notices requiring us to change the way we use personal data or our marketing practices. For example, under the GDPR we may be subject to fines of up to €20 million or up to 4% of the total worldwide annual group turnover of the preceding financial year (whichever is higher). We may also be subject to other liabilities, as well as negative publicity and a potential loss of business.

Restrictions on the collection, use, sharing or disclosure of personal information or additional requirements and liability for security and data integrity could require us to modify our solutions and features, possibly in a material manner, could limit our ability to develop new products and features and could subject us to increased compliance obligations and regulatory scrutiny.

46

Our dependence on international customers and operations also subjects us to a range of other additional regulatory, operational, financial and political risks that could adversely affect our financial results.

For fiscal years 2019 and 2020, approximately 80.5% and 81.7%, respectively, of our net sales were to customers outside of the United States, and for the three-month periods ended June 28, 2019 and June 26, 2020, approximately 81.2% and 88.7%, respectively, of our net sales were to customers outside of the United States. In addition, a substantial majority of our products are assembled and tested at facilities outside of the United States. Our principal assembly and test facilities are located in the Philippines at our AMPI Facility and in Thailand at our AMTC Facility. We also rely on several other wafer fabrication manufacturing partners located throughout Asia. Any conflict or uncertainty in this region, including public health or safety concerns or natural disasters, could have a material adverse effect on our business, financial condition and results of operations. Moreover, conducting business outside the United States subjects us to a number of additional risks and challenges, including:

These factors, individually or in combination, could impair our ability to effectively operate one or more of our foreign facilities or deliver our products, result in unexpected and material expenses, or cause an unexpected decline in the demand for our products in certain countries or regions. Our failure to manage the risks and challenges associated with our international business and operations could have a material adverse effect on our business.

End-user demand for certain HEVs, EVs and green energy products often depends on the availability of rebates, tax credits and other financial incentives. The reduction, modification, expiration or elimination of such government economic incentives could reduce end-user demand and thus affect our customers’ demand for our products.

The U.S. federal government, some state and local governments, as well as foreign governments provide certain incentives to end-users and purchasers of certain HEVs, EVs and green energy products in the form of rebates, tax credits and other financial incentives. End-users often rely on these governmental rebates, tax credits and other financial incentives to significantly lower the purchase price of these products. However, these incentives may expire on a particular date, end when the allocated funding is exhausted, or be reduced or terminated as a matter of regulatory or legislative policy. Any slowdown in end-user demand for our products as a result of such changes to these incentives could adversely affect our business, financial condition and results of operations.

We will lose sales if we are unable to obtain government authorization to export certain of our products, and we will be subject to legal and regulatory consequences if we do not comply with applicable export control laws and regulations.

Exports of certain of our products and other products, including Voxtel products, are subject, or could be subject in the future, to export controls imposed by the U.S. government and administered by the U.S. Departments of State and Commerce and a small number of our products are subject to export controls imposed by the International Traffic in Arms Regulations (“ITAR”), administered by Department of State’s Directorate of Defense Trade Controls. In certain instances, these regulations may require pre-shipment authorization from the administering department. For products subject to the Export Administration Regulations (“EAR”), administered by the Department of Commerce’s Bureau of Industry and Security, the requirement for a license is dependent on the type and end use of the product, the final destination, the identity of the end user and whether a license exception might apply. Virtually all exports of products subject to the ITAR require a license. Certain of our products are subject to EAR and some products, including certain products developed with government funding, which are subject to ITAR. Products developed and manufactured in our foreign locations are subject to export controls of the applicable foreign nation. Obtaining export licenses can be difficult, costly and time-consuming and we may not always be successful in obtaining necessary export licenses, and our failure to obtain required import or export approval for our products or limitations on our ability to export or sell our products imposed by these laws may harm our international and domestic revenues. Noncompliance with these laws could have negative consequences, including government investigations, penalties and reputational harm. The absence of comparable restrictions on competitors in other countries may adversely affect our competitive position.

Failure to obtain export licenses for our products or having one or more of our customers be restricted from receiving exports from us could significantly reduce our net sales and materially and adversely affect our business, financial condition and results of operations.

Changing currency exchange rates may adversely affect our business, financial condition, results of operations and cash flows.

We have operations and assets in the U.S. as well as foreign jurisdictions and we prepare our consolidated financial statements in U.S. dollars, but a portion of our earnings and expenditures are denominated in other currencies. We therefore must translate our foreign assets, liabilities, revenue and expenses into U.S. dollars at applicable exchange rates. Consequently, fluctuations in the value of foreign currencies relative to the U.S. dollar may negatively affect the value of these items in our financial statements. In addition, since many of our sales in foreign jurisdictions are denominated in U.S. dollars, fluctuations in the value of foreign currencies relative to the U.S. dollar may effectively increase the price of our products in the currency of the jurisdiction in which the sale took place and may result in our products becoming too expensive for non-U.S. customers who do not conduct their business in U.S. dollars. Furthermore, currency exchange rates have been especially volatile in the recent

48

past, and these currency fluctuations may make it difficult for us to predict our results of operations. To the extent we fail to manage our foreign currency exposure adequately, we may suffer losses in the value of our net foreign currency investment, and our business, financial condition, results of operations and cash flows may be negatively affected.

We have and expect to continue to pursue acquisitions of and investments in new businesses, products or technologies, joint ventures and other strategic transactions that involve numerous risks and could disrupt our business and harm our financial condition and results of operations.

As part of our business strategy, we make acquisitions of and investments in new businesses, products and technologies and enter into joint ventures and other strategic relationships in the ordinary course. Our ability to grow our revenues, earnings and cash flow at or above our historic rates depends in part upon our ability to identify and successfully acquire and integrate businesses at acceptable prices, realize anticipated synergies and make appropriate investments that support our long-term strategy. We may not be able to consummate acquisitions at rates similar to the past, which could adversely impact our growth rate and the trading price of our common stock. Promising acquisitions and investments are difficult to identify and complete for a number of reasons, including high valuations, competition among prospective buyers, the availability of affordable funding in the capital markets and the need to satisfy applicable closing conditions and obtain applicable antitrust and other regulatory approvals on a timely basis and on acceptable terms. In addition, competition for acquisitions and investment may result in higher purchase prices. Changes in accounting or regulatory requirements or instability in the credit markets could also adversely impact our ability to consummate acquisitions and investments on acceptable terms or at all.

In addition, even if we are able to consummate acquisitions and enter into joint ventures and other strategic relationships, these transactions and relationships present a number of potential risks and challenges that could, if not met, disrupt our business operations, increase our operating costs, negatively affect our growth rate and the trading price of our common stock, and may have a material adverse effect on our business, financial condition and results of operations. In addition, any acquisition, investment, joint venture or other strategic transaction we may enter into in the future, involve a number of additional financial, accounting, managerial, operational, legal, regulatory and other risks, which may include, among others:

49

Furthermore, potential acquisitions, investments, joint ventures and other strategic transactions, whether or not consummated, may divert our management’s attention and require considerable cash outlays at the expense of our existing operations. This, and any of the risks set forth above, could materially and adversely affect our business, financial condition, results of operations and profitability.

Our ability to raise capital in the future may be limited and could prevent us from executing our growth strategy.

Our ability to operate and expand our business depends on the availability of adequate capital, which in turn depends on cash flow generated by our business and the availability of borrowings under our credit facilities and other debt, equity or other applicable financing arrangements. We believe that our existing cash resources, together with the anticipated net proceeds of this offering and our access to the capital markets, will be sufficient to finance our continued operations, growth strategy, planned capital expenditures and the additional expenses we expect to incur as a public company for at least the next 12 months. However, we have based this estimate on our current operating plans and expectations, which are subject to change, and cannot assure you that that our existing resources will be sufficient to meet our future liquidity needs. We may require additional capital to respond to business opportunities, challenges, acquisitions or other strategic transactions and/or unforeseen circumstances. The timing and amount of our working capital and capital expenditure requirements may vary significantly depending on numerous factors, including:

If our capital resources are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity securities or debt securities or obtain debt financing. The sale of additional equity securities or convertible

50

debt securities would result in additional dilution to our stockholders. Additional debt would result in increased expenses and could result in covenants that would restrict our operations and our ability to incur additional debt or engage in other capital-raising activities. We have not made arrangements to obtain additional financing and there is no assurance that financing, if required, will be available in amounts or on terms acceptable to us, if at all. If we are unable to obtain adequate financing or financing on terms satisfactory to us, when we require it, our ability to continue to grow and support our business and respond to business opportunities and challenges could be significantly limited.

We may not be able to effectively manage our growth, and we may need to incur significant expenditures to address the additional operational and control requirements of our growth, either of which could harm our business and operating results.

To continue to grow, we must continue to expand our operational, engineering, accounting and financial systems, procedures, controls and other internal management systems. This may require substantial managerial and financial resources, and our efforts in this regard may not be successful. Our current systems, procedures and controls may not be adequate to support our future operations. Unless our growth results in an increase in our revenues that is proportionate to the increase in our costs associated with this growth, our operating margins and profitability will be adversely affected. If we fail to adequately manage our growth, improve our operational, financial and management information systems, or effectively motivate and manage our new and future employees, it could adversely affect our business, financial condition and results of operations.

We depend on key and highly skilled personnel to operate our business, and if we are unable to retain our current personnel and hire additional personnel, our ability to develop and market our products could be harmed, which in turn could adversely affect our financial results.

Our success depends to a large extent upon the continued services of our executive officers, managers and skilled personnel, including our development engineers. In particular, we are highly dependent on the services of Ravi Vig, our Chief Executive Officer, who, after over 30 years of service with our company, has been critical in the development and growth of our business and strategic direction. From time to time, there may be changes in our executive management team or other key personnel, which could disrupt our business. Generally, our employees are not bound by obligations that require them to continue to work for us for any specified period and, therefore, they could terminate their employment with us at any time. Moreover, our employees are generally not subject to non-competition agreements. Given these limitations, we may not be able to continue to attract, retain and motivate qualified personnel necessary for our business. In addition, we recruit from a limited pool of engineers with expertise in analog mixed-signal semiconductor design and the competition for such personnel can be intense. The loss of one or more of our executive officers, particularly Ravi Vig, our Chief Executive Officer, or other key personnel or our inability to locate suitable or qualified replacements could be significantly detrimental to our product development efforts and could have a material adverse effect on our business, financial condition and results of operation. In addition, we must attract and retain highly qualified personnel, including certain foreign nationals who are not U.S. citizens or permanent residents, many of whom are highly skilled and constitute an important part of our U.S. workforce, particularly in the areas of engineering and product development. Our ability to hire and retain these employees and their ability to remain and work in the U.S. are impacted by laws and regulations, as well as by procedures and enforcement practices of various government agencies. Changes in immigration laws, regulations or procedures, including those that may be enacted by the current U.S. presidential administration, may adversely affect our ability to hire or retain such workers, increase our operating expenses and negatively impact our ability to deliver our products and services, any of which would adversely affect our business, financial condition and results of operations.

Our failure to comply with the large body of laws and regulations to which we are subject could have a material adverse effect on our business and operations.

We are subject to regulation by various governmental agencies in the United States and other jurisdictions in which we operate. These laws and regulations (and the government agency responsible for their enforcement in

51

the United States) cover: radio frequency emission regulatory activities (Federal Communications Commission); anti-trust regulatory activities (Federal Trade Commission and Department of Justice); consumer protection laws (Federal Trade Commission); import/export regulatory activities (Department of Commerce); product safety regulatory activities (Consumer Products Safety Commission); worker safety (Occupational Safety and Health Administration and similar state and local agencies); environmental protection (Environmental Protection Agency and similar state and local agencies); employment matters (Equal Employment Opportunity Commission); and tax and other regulations by a variety of regulatory authorities in each of the areas in which we conduct business. In certain jurisdictions, regulatory requirements in one or more of these areas may be more stringent than in the United States.

In the area of employment matters, we are subject to a variety of federal, state and foreign employment and labor laws and regulations, including the Americans with Disabilities Act, the Federal Fair Labor Standards Act, the WARN Act and other regulations related to working conditions, wage and hour pay, overtime pay, employee benefits, anti-discrimination, and termination of employment. Noncompliance with any of these applicable regulations or requirements could subject us to investigations, sanctions, enforcement actions, fines, damages, penalties, or injunctions. In certain instances, former employees have brought claims against us and we expect that we will encounter similar actions against us in the future. An adverse outcome in any such litigation could require us to pay damages, attorneys’ fees and costs. These enforcement actions could harm our reputation, business, financial condition and results of operations. If any governmental sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, financial condition and results of operations could be materially and adversely affected. In addition, responding to any action will likely result in a significant diversion of management’s attention and resources and an increase in professional fees.

Our failure to comply with the Foreign Corrupt Practices Act, other applicable anti-corruption and anti-bribery laws, and applicable trade control laws could subject us to penalties and other adverse consequences.

We have extensive international operations and a substantial portion of our business, particular with respect to our manufacturing processes, is conducted outside of the United States. Our operations are subject to the U.S. Foreign Corrupt Practices Act (the “FCPA”), as well as the anti-corruption and anti-bribery laws in the countries where we do business. The FCPA prohibits covered parties from offering, promising, authorizing or giving anything of value, directly or indirectly, to a “foreign government official” with the intent of improperly influencing the official’s act or decision, inducing the official to act or refrain from acting in violation of lawful duty, or obtaining or retaining an improper business advantage. The FCPA also requires publicly traded companies to maintain records that accurately and fairly represent their transactions, and to have an adequate system of internal accounting controls. In addition, other applicable anti-corruption laws prohibit bribery of domestic government officials, and some laws that may apply to our operations prohibit commercial bribery, including giving or receiving improper payments to or from non-government parties, as well as so-called “facilitation” payments. In addition, we are subject to U.S. and other applicable trade control regulations that restrict with whom we may transact business, including the trade sanctions enforced by the U.S. Treasury, Office of Foreign Assets Control.

Though we maintain policies, internal controls and other measures reasonably designed to promote compliance with applicable anticorruption and anti-bribery laws and regulations, and certain safeguards designed to ensure compliance with U.S. trade control laws, our employees or agents may nevertheless engage in improper conduct for which we might be held responsible. Any violations of these anti-corruption or trade controls laws, or even allegations of such violations, can lead to an investigation and/or enforcement action, which could disrupt our operations, involve significant management distraction, and lead to significant costs and expenses, including legal fees. If we, or our employees or agents acting on our behalf, are found to have engaged in practices that violate these laws and regulations, we could suffer severe fines and penalties, profit disgorgement, injunctions on future conduct, securities litigation, bans on transacting government business, delisting from securities exchanges and other consequences that may have a material adverse effect on our business, financial condition and results of operations. In addition, our reputation, our net sales or our stock price could be adversely affected if we

52

become the subject of any negative publicity related to actual or potential violations of anti-corruption, anti-bribery or trade control laws and regulations.

In order to comply with environmental and occupational health and safety laws and regulations, we may need to modify our activities or incur substantial costs, and such laws and regulations, including any failure to comply with such laws and regulations, could subject us to substantial costs, liabilities, obligations and fines, or require us to have our suppliers alter their processes.

The semiconductor industry is subject to a variety of international, federal, state, local and non-U.S. laws and regulations governing pollution, environmental protection and occupational health and safety, including those relating to the release, storage, use, discharge, handling, generation, transportation, disposal, product composition and labeling of, and human exposure to, hazardous and toxic materials, and the investigation and cleanup of contaminated sites, including sites we currently or formerly owned or operated, due to the release of hazardous materials, regardless of whether we caused such release. In addition, we may be liable for joint and several costs associated with investigation and remediation of sites at which we have arranged for the disposal of hazardous wastes if such sites become contaminated, even if we fully comply with applicable environmental laws and regulations. Failure to comply with such laws and regulations could subject us to civil or criminal costs, obligations, sanctions or property damage or personal injury claims, or suspension of our facilities’ operating permits. Compliance with current or future environmental and occupational health and safety laws and regulations could restrict our ability to expand our business or require us to modify processes or incur other substantial expenses which could harm our business. In the event of an incident involving hazardous materials, we could be liable for damages and such liability could exceed the amount of our liability insurance coverage and the resources of our business. In addition, in the event of the discovery of contaminants or the imposition of clean up obligations for which we are responsible, we may be required to take remedial or other measures which could have a material adverse effect on our business, financial condition and results of operations. In response to environmental concerns, some customers and government agencies impose requirements for the elimination and/or labeling of hazardous substances, such as lead (which is widely used in soldering connections in the process of semiconductor packaging and assembly), in electronic equipment, as well as requirements related to the take-back of products discarded by customers. For example, the EU adopted its Restriction of Hazardous Substance Directive (“RoHS”) which prohibits, with specified exceptions, the sale in the EU market of electrical and electronic equipment containing more than agreed levels of lead or other hazardous materials and China has enacted similar regulations. Environmental and occupational health and safety laws and regulations have tended to become more stringent over time, causing a need to redesign technologies, imposing greater compliance costs and increasing risks and penalties associated with violations, which could seriously harm our business.

The issuance of new accounting standards or future interpretations of existing accounting standards could adversely affect our operating results.

We prepare our financial statements in accordance with GAAP. A change in those principles could have a significant effect on our reported results and might affect our reporting of transactions completed before a change is announced. GAAP is issued and subject to interpretation by the Financial Accounting Standards Board, the Securities and Exchange Commission (the “SEC”) and various other bodies formed to promulgate and interpret accounting principles. A change in these principles or interpretations could have a significant effect on our reported financial results, and could affect the reporting of transactions completed before the announcement of a change. The issuance of new accounting standards or future interpretations of existing accounting standards, or changes in our business practices or estimates, could result in future changes in our revenue recognition or other accounting policies that could have a material adverse effect on our business, financial condition and results of operations.

53

We could be subject to changes in tax rates or the adoption of new tax legislation, whether in or out of the United States, or could otherwise have exposure to additional tax liabilities, which could adversely affect our results of operations or financial condition.

As a multinational business, we are subject to income and other taxes in both the United States and various foreign jurisdictions. Changes to tax laws or regulations in the jurisdictions in which we operate, or in the interpretation of such laws or regulations, could, significantly increase our effective tax rate and reduce our cash flow from operating activities, and otherwise have a material adverse effect on our financial condition. In addition, other factors or events, including business combinations and investment transactions, changes in the valuation of our deferred tax assets and liabilities, adjustments to taxes upon finalization of various tax returns or as a result of deficiencies asserted by taxing authorities, increases in expenses not deductible for tax purposes, changes in available tax credits, changes in transfer pricing methodologies, other changes in the apportionment of our income and other activities among tax jurisdictions, and changes in tax rates, could also increase our effective tax rate.

Our tax filings are subject to review or audit by the U.S. Internal Revenue Service (the “IRS”) and state, local and foreign taxing authorities. For example, we recently settled a tax audit relating to fiscal years 2016, 2017 and 2018. We exercise significant judgment in determining our worldwide provision for taxes and, in the ordinary course of our business, there may be transactions and calculations where the proper tax treatment is uncertain. We may also be liable for taxes in connection with businesses we acquire. Our determinations are not binding on the IRS or any other taxing authorities, and accordingly the final determination in an audit or other proceeding may be materially different than the treatment reflected in our tax provisions, accruals and returns. An assessment of additional taxes because of an audit could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Further changes in the tax laws of foreign jurisdictions could arise, in particular, as a result of the base erosion and profit shifting project that was undertaken by the Organization for Economic Co-operation and Development (the “OECD”). The OECD, which represents a coalition of member countries, recommended changes to numerous long-standing tax principles. These changes, if adopted, could increase tax uncertainty and may adversely affect our provision for income taxes and increase our tax liabilities.

Litigation, including securities class action litigation, may impair our reputation and lead us to incur significant costs.

From time to time, we have been, and in the future anticipate will be, party to various lawsuits and claims arising in the normal course of business, which may include lawsuits or claims relating to contracts, third-party manufacturers or subcontractors, intellectual property, employment matters, environmental matters or other aspects of our business. In addition, in the past, following periods of volatility in the overall market and the market price of a company’s securities, securities class action litigation has often been instituted against companies that experienced such volatility. Litigation, if instituted against us, whether or not valid and regardless of outcome, could result in substantial costs, reputational harm and a diversion of our management’s attention and resources. In addition, we may be required to pay damage awards or settlements or become subject to injunctions or other equitable remedies, which could have a material adverse effect on our business, financial condition, results of operations and cash flows. The outcome of litigation is often difficult to predict, and any litigation may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Although we have various insurance policies in place, the potential liabilities associated with litigation matters now or that could arise in the future, could be excluded from coverage or, if covered, could exceed the coverage provided by such policies. In addition, insurance carriers may seek to rescind or deny coverage with respect to any claim or lawsuit. If we do not have sufficient coverage under our policies, or if coverage is denied, we may be required to make material payments to settle litigation or satisfy any judgment. Any of these

54

consequences could have a material adverse effect on our business, financial condition, results of operations and cash flows.

The estimates of market opportunity and growth forecasts included in this prospectus may prove to be inaccurate, and even if the markets in which we compete achieve the forecasted growth, our business could fail to grow at similar rates, if at all.

Market opportunity estimates and growth forecasts are inherently uncertain. Our estimates regarding the expected growth in our served available markets are based on our experience, as well as internal research and industry forecasts, which are subject to a number of estimates and assumptions. While we believe our assumptions and the data underlying our estimates to be reasonable, these assumptions and estimates may not be correct and the conditions supporting our assumptions or estimates may change at any time, thereby reducing the predictive accuracy of these underlying factors. As a result, our estimates regarding the size and expected growth rates of our served available markets may prove to be incorrect. If our served available markets are smaller than we have estimated, our sales growth and/or market share may fail to reach the levels implied by these estimates.

Risks Related to this Offering and Ownership of Our Common Stock

We are an “emerging growth company,” and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the JOBS Act, and we could remain an emerging growth company until the last day of our fiscal year following the fifth anniversary of the closing of this offering. For as long as we continue to be an emerging growth company, we may choose to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including, but not limited to:

In addition, as an emerging growth company, we are only permitted to provide two years of audited financial statements and two years of selected financial data (in addition to any required interim financial statements and selected financial data) in this prospectus, and to present correspondingly reduced disclosure in “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

We have elected to take advantage of this reduced disclosure obligation and certain of the other exemptions described above in the registration statement of which this prospectus is a part and may elect to take advantage of these and other reduced reporting requirements in the future. As a result, the information that we provide to our stockholders may be different than the information you might receive from other public reporting companies in which you hold equity interests. In addition, the JOBS Act permits emerging growth companies to delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected to use this extended transition period for complying with new or revised accounting standards until the

55

earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our consolidated financial statements and the reported results of operations contained therein may not be directly comparable to those of other public companies. We cannot predict whether investors will find our common stock less attractive because of our reliance on these exemptions. If some investors do find our common stock less attractive, there may be a less active trading market for our common stock and our stock price may be reduced or more volatile.

We will remain an emerging growth company, and will be able to take advantage of the foregoing exemptions, until the last day of our fiscal year following the fifth anniversary of the closing of this offering or such earlier time that we otherwise cease to be an emerging growth company, which will occur upon the earliest of (i) the last day of the first fiscal year in which our annual gross revenues are $1.07 billion or more; (ii) the date on which we have, during the previous three-year period, issued more than $1.0 billion in non-convertible debt securities; and (iii) the date that we become a “large accelerated filer” as defined in Rule 12b-2 under the Exchange Act, which will occur as of the end of any fiscal year in which we (x) the market value of our common equity held by non-affiliates is $700 million or more as of the last business day of our most recently completed second fiscal quarter, (y) we have been required to file annual and quarterly reports under the Exchange Act for a period of at least 12 months and (z) have filed at least one annual report pursuant to the Exchange Act.

Our principal stockholders Sanken and OEP will continue to have substantial control over us after this offering, which could limit your ability to influence the outcome of key transactions, including a change of control, and otherwise affect the prevailing market price of our common stock.

After this offering, our principal stockholders Sanken and OEP will beneficially own, in the aggregate, approximately 80.2% of our outstanding common stock, and approximately 78.2% of our outstanding common stock if the underwriters’ option to purchase additional shares of common stock in this offering is exercised in full. See “Principal and Selling Stockholders.” In addition, as described in more detail under “Certain Relationships and Related Party Transactions—Stockholders’ Agreements,” the New Stockholders’ Agreement, which will become effective prior to the closing of this offering, gives each of Sanken and the OEP Investor (in each case, for so long such party beneficially owns at least 5% of our common stock) certain rights with respect to the composition of our board of directors, including certain rights to designate members of our board of directors. As a result, these stockholders and their affiliates will have significant influence over the management and affairs of our company, as well as the ability to control the outcome of matters submitted to our stockholders for approval, including the election of directors and the approval of significant corporate transactions, including any merger, consolidation or sale of all or substantially all of our assets and the issuance or redemption of equity interests in certain circumstances. The interests of these stockholders may not always coincide with, and in some cases may conflict with, our interests and the interests of our other stockholders. For instance, these stockholders could attempt to delay or prevent a change in control of our company, even if such change in control would benefit our other stockholders, which could deprive our stockholders of an opportunity to receive a premium for their common stock. This concentration of ownership may also affect the prevailing market price of our common stock due to investors’ perceptions that conflicts of interest may exist or arise. As a result, this concentration of ownership may not be in your best interests.

Our Post-IPO Certificate of Incorporation will provide that the doctrine of “corporate opportunity” will not apply with respect to any director or stockholder who is not employed by us or our subsidiaries.

The doctrine of corporate opportunity generally provides that a corporate fiduciary may not develop an opportunity using corporate resources, acquire an interest adverse to that of the corporation or acquire property that is reasonably incident to the present or prospective business of the corporation or in which the corporation has a present or expectancy interest, unless that opportunity is first presented to the corporation and the corporation chooses not to pursue that opportunity. The doctrine of corporate opportunity is intended to preclude officers, directors and other fiduciaries from personally benefiting from opportunities that belong to the corporation. Our Post-IPO Certificate of Incorporation, which will become effective upon the closing of this

56

offering, will provide that the doctrine of “corporate opportunity” will not apply with respect to the OEP Investor or its affiliates (other than us and our subsidiaries) any of its or their respective principals, members, directors, partners, stockholders, officers, employees or other representatives (other than any such person who is also an employee of ours or our subsidiaries) or to any director or stockholder who is not employed by us or our subsidiaries (collectively, “Exempted Persons”). The Exempted Persons will therefore have no duty to communicate or present corporate opportunities to us, and will have the right to either hold any corporate opportunity for their own account and benefit or to recommend, assign or otherwise transfer such corporate opportunity to persons other than us, including to any other director or stockholder who is not employed by us or our subsidiaries.

As a result, the Exempted Persons will generally not be prohibited from operating or investing in competing businesses. We therefore may find ourselves in competition with any one or more of these parties, and we may not have knowledge of, or be able to pursue, transactions that could potentially be beneficial to us. To the extent we find ourselves in competition with Exempted Persons, we may lose a corporate opportunity or suffer competitive harm, which could negatively impact our business, financial condition, results of operations or prospects.

There has been no prior public market for our common stock, and an active trading market may never develop or be sustained.

Prior to this offering, there has been no public market for our common stock. The initial public offering price for the shares was determined by negotiations between us, the selling stockholders and the representatives of the underwriters and may not be indicative of prices that will prevail in the trading market following the closing of this offering. Although our common stock has been approved for listing on the Nasdaq Global Select Market, an active trading market for our common stock may never develop or be sustained following this offering. If an active market for our common stock does not develop, it may be difficult for you to sell shares you purchase in this offering without depressing the market price for our common stock, or at all. An inactive trading market may also impair our ability to raise capital by selling shares of our common stock and enter into strategic partnerships or acquire other complementary products, technologies or businesses by using shares of our common stock as consideration. Furthermore, although our common stock has been approved for listing on the Nasdaq Global Select Market, there can be no guarantee that we will continue to satisfy the continued listing standards of the Nasdaq Global Select Market. If we fail to satisfy the continued listing standards, we could be de-listed, which would negatively impact the value and liquidity of your investment.

Our stock price may be volatile, and investors in our common stock may not be able to resell shares of our common stock at or above the price paid, or at all.

The trading price of our common stock following this offering could be volatile and subject to wide fluctuations in response to various factors, many of which are beyond our control, including, but not limited to:
