[added] As discussed in Notes 2 and 17 to the Consolidated Financial Statements included elsewhere in this Annual Report on Form 10-K, we restated our audited consolidated financial statements for the fiscal year ended December 31, 2024 and our unaudited condensed consolidated financial statements for the quarterly periods ended March 31, 2025, June 30, 2025 and September 30, 2025 after we determined that we had not appropriately accounted for deferred income taxes associated with a one-time tax incentive granted by a certain foreign jurisdiction. As a result of this error and the resulting restatement of our audited consolidated financial statements and unaudited condensed consolidated financial statements for the impacted periods, we have incurred, and may continue to incur, unanticipated accounting and legal fees in connection with or related to the restatement, and are subject to a number of additional risks and uncertainties, including the increased possibility of litigation and regulatory inquiries. The restatement may adversely affect investor confidence in the accuracy of our financial disclosures, may harm our reputation and our business and could cause our stock price to decline.

01RemovedItem 1A › Risks Associated with Supply and Manufacturing › We currently depend on third-party suppliers to provide us with wafers for our products. If any of our wafer suppliers are acquired, become insolvent or capacity constrained, or are otherwise unable to provide us sufficient wafers at acceptable yields or at anticipated costs, our revenue and gross margin may decline or we may not be able to fulfill our customer orders.

Summary · quote-checked

Removed disclosure that customer order cancellations could leave the company obligated to purchase unsellable wafers, harming financial results and cash flows.

The removed paragraph disclosed a specific supply-chain exposure and potential obligation with consequences for financial condition, results of operations and cash flows.

Why the model ranked it here

The removal eliminates disclosure of a specific customer-cancellation exposure that could leave the company obligated to buy unsellable wafers and impair cash flows.

Filing text · FY2024 10-K · filed Mar 3, 2025

Should any of our suppliers be acquired or become insolvent or capacity constrained, we may not be able to fulfill our customer orders, which would likely cause a decline in our revenue. While certain aspects of our relationships with these suppliers are contractual, many important aspects of our relationships depend on our suppliers' continued cooperation and our management of such relationships with the suppliers. Our relationships could be negatively impacted by changes in control or changes in the management team of the suppliers. In addition, the fabrication of ICs is a highly complex and precise process. Problems in the fabrication process can cause a substantial percentage of wafers to be rejected or numerous ICs on each wafer to be non-functional. This could potentially reduce yields and supply of our products. The failure of our suppliers to provide wafers at acceptable yields could prevent us from fulfilling our customer orders and would likely cause a decline in our revenue. In addition, adverse macroeconomic conditions, such as inflationary pressures resulting from worldwide supply chain constraints and other factors, have increased, and may continue to increase, the prices we pay to our suppliers. As a result of the increased costs, we have raised, and may be required to further raise the prices of our products in order to remain profitable, which could result in a loss of customers and reduced revenue. If we are unable to increase our prices to reflect higher costs, our margins will decrease. Further, as is common in the semiconductor industry, our customers may reschedule or cancel orders on relatively short notice. [removed] If our customers cancel orders after we submit a committed forecast to our suppliers for the corresponding wafers, we may be required to purchase wafers that we may not be able to resell, which would adversely affect our financial condition, results of operations and cash flows.

Summary · quote-checked

Removed disclosure of Chinese cybersecurity and data-protection laws, regulatory uncertainty, government oversight, and potential fines for noncompliance.

The removed paragraph described specific legal requirements, regulatory uncertainty, cross-border data-transfer approvals, and fines, so its deletion changes disclosed regulatory and compliance risks.

Why the model ranked it here

The removal eliminates disclosure of Chinese data-security requirements, regulatory uncertainty, government oversight, and potential fines affecting the company’s compliance exposure.

Filing text · FY2024 10-K · filed Mar 3, 2025

[removed] Privacy, cyber security, and data protection are becoming increasingly significant issues. To address these issues, the Standing Committee of the National People's Congress promulgated the Cyber Security Law of the People's Republic of China (the "Cyber Security Law"), which took effect on June 1, 2017. The Cyber Security Law sets forth various requirements relating to the collection, use, storage, disclosure and security of data, among other things. On June 10, 2021, the National People's Congress passed the Data Security Law of the People's Republic of China (the "Data Security Law"), which became effective on September 1, 2021. The Data Security Law is the first comprehensive data security legislation in China, which becomes a key supplement to the Cyber Security Law and aims to regulate a wide range of issues in relation to the collection, storage, processing, use, provision, transaction and publication of any kind of data. Various Chinese agencies are expected to issue additional regulations in the future to define these requirements more precisely. For example, the Personal Information Protection Law ("PIPL"), took effect on November 1, 2021. PIPL is aimed at protecting and controlling the use and transfer of personal data in China. There is significant uncertainty in how regulators will interpret and enforce the law, and it contains provisions that allow substantial government oversight and include fines for failure to obtain required approval from China's cyber and data protection regulators for cross-border transfers of personal data.

Summary · quote-checked

The disclosure shifts from a remediated weakness and potential future weaknesses to an identified deferred-tax weakness, ineffective controls, misstatement risk, and possible regulatory sanctions.

The paragraph adds a specific control deficiency, current ineffectiveness, risks of untimely misstatements and reporting delays, potential SEC investigations and sanctions, and adverse effects on common-stock value.

Why the model ranked it here

The company now reports ineffective internal controls tied to a specific deferred-tax weakness, with heightened misstatement, reporting-delay and regulatory-sanction exposure.

As more fully disclosed in Item 9A.

Due to this finding of a material weakness, we concluded that our internal control over financial reporting was not effective as of December 31, [added] 2024 and December 31, 2025.

The risk disclosure adds customer switching and supplier-commitment exposure, including potential purchases of unusable supplies and adverse financial effects.

The paragraph adds substantive customer and supplier dependencies and a potential obligation affecting financial condition, results of operations and cash flows; this is more than wording.

Why the model ranked it here

Customer cancellations can now leave the company obligated to buy unusable supplies, creating a direct exposure to financial condition, results and cash flows.

The added disclosure introduces restrictions affecting purchases, investments and collaborations, plus possible fines, penalties and enforcement action, creating a substantively new legal and operational risk.

New investment restrictions may disrupt purchasing, investments and collaborations while exposing the company to fines, penalties and enforcement action.

Filing text · FY2024 10-K · filed Mar 3, 2025

We are subject to U.S. laws and regulations that could limit or restrict the export of some of our products, supplies and services and may restrict our transactions with certain customers, business partners and other individuals, including, in certain cases, dealings with or between us and our employees and subsidiaries. In certain circumstances, export controls and economic sanctions may prohibit the export of certain products, services and technologies, and in other circumstances we may be required to obtain an export license before exporting the controlled item. Compliance with these laws and regulations has not materially limited our operations or our sales, but could in the future, which would materially and adversely affect our business and results of operations. We maintain an export compliance program, but our compliance controls could be circumvented, exposing us to legal liabilities, sanctions and restrictions on our business. We must also comply with export restrictions and laws imposed by other countries affecting trade and investments. Although these restrictions and laws have not materially restricted our operations in the past, they could do so in the future, which would materially and adversely affect our business and results of operations. In addition, U.S. laws and regulations and sanctions, or threat of sanctions, that could limit or restrict the export of some of our products and services may also encourage our customers to develop their own solutions to replace our products, or seek to obtain a greater supply of similar or substitute products from our competitors that are not subject to these restrictions, which could materially and adversely affect our business, financial condition and results of operations. Furthermore, our customers' end products and systems that incorporate our components could be subject to export laws, trade policies and other sales restrictions, which could indirectly affect our business, financial conditions and results of operations. For example, the increasing focus on the risks and strategic importance of AI technologies has resulted in regulatory restrictions that target products and services capable of enabling or facilitating AI, and may in the future result in additional restrictions impacting the sales of AI technologies or products. Any of such regulatory restrictions could, in turn, impact the sales of our products supporting AI applications. [removed] There has been increasing rhetoric, in some cases coupled with legislative or executive action, from several U.S. and foreign leaders regarding tariffs against foreign imports of certain products and materials. Specifically, there have been several rounds of U.S. tariffs on Chinese goods that have taken effect in the past few years, as well as additional tariffs imposed by the [removed] new U.S. administration in [removed] January 2025, some of which prompted, and could prompt additional, retaliatory Chinese tariffs on U.S. goods. The institution of trade tariffs both globally and between the U.S. and China specifically carries the risk of negatively affecting both countries' overall economic condition, as well as our business and financial results. If these tariffs continue or additional tariffs are imposed in the future, they could have a negative impact on us as we have significant operations in China and the U.S. Additionally, the imposition of tariffs is dependent upon the classification of goods under the U.S. Harmonized Tariff System ("HTS") and the country of origin of the goods. Determination of the HTS and the origin of the goods is a technical matter that can be subjective in nature. Accordingly, although we believe our classifications of both HTS and origin are appropriate, there is no certainty that our assessment will be consistent with that of the U.S. government, particularly under the new U.S. administration. If the U.S. government does not agree with our determinations, we could be required to pay additional amounts, our ability to sell products in the U.S. may be restricted or eliminated and we may incur substantial additional costs or potential penalties.

Summary · quote-checked

The disclosure shifts from planned diversification uncertainty to progress made and adds risks involving higher costs, regional exposure, qualification costs, product quality and supplier capacity.

The paragraph substantively changes management’s diversification status and adds new cost, geographic, quality and demand-related risks, rather than merely rephrasing the existing concentration risk.

Why the model ranked it here

Management now reports progress diversifying capacity outside China while acknowledging potentially higher costs and new qualification, quality and supplier-capacity risks.

A significant portion of our manufacturing, testing, assembly and packaging capacity comes from key suppliers located in China. As a result, we are subject to significant political, regulatory, tax, economic, foreign exchange, and operational risks due to this geographic concentration in our business.

Although we have made significant progress in diversifying capacity outside of China, there is no guarantee that our progress is sufficient or will be sufficient to mitigate these risks. Furthermore, we cannot guarantee that our new manufacturing, testing, assembly and packaging partners will not be costlier than our legacy partners in China. In addition, as we pivot our manufacturing, testing, assembly and packaging capacity concentration from China to another region, we will be [added] subject to the risks of doing business in that particular region. If we decide to further diversify our capacity, it could be costly due to lost pricing benefits from production volume, as well as the time and cost to qualify new partners. Furthermore, there is no guarantee that the quality of the products from new suppliers will be acceptable to us, or that these suppliers will be able to meet our demand.

The added sentence introduces a new adverse-outcome risk tied to assumptions, analyst expectations, operating results, and trading price, beyond wording or accounting terminology changes.

Filing text · FY2024 10-K · filed Mar 3, 2025

Certain areas of our accounting, including but not limited to our income tax provision and inventory [removed] reserves, require a significant amount of management [removed] judgments or could be complex. For example, due to the complexity associated with the calculation of our tax provision, including the effects of the enactment of new tax laws, we engage third-party tax advisors to assist us in the calculation. If we or our tax advisors fail to resolve or fully understand certain issues that we may have had in the past and issues that may arise in the future, we could be subject to errors, which, if material, would result in a restatement of our financial statements. Restatements are generally costly and could adversely impact our results of operations, damage our reputation, and/or have a negative impact on the trading price of our common stock.

Certain areas of our accounting, including but not limited to our income tax provision and inventory [added] valuation require a significant amount of management [added] judgment and are complex. We base our management judgements on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, as provided in the section titled Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations. For example, due to the complexity associated with the calculation of our tax provision, including the effects of the enactment of new tax laws, we engage third-party tax advisors to assist us in the calculation. If we or our tax advisors fail to resolve or fully understand certain issues that we may have had in the past and issues that may arise in the future, we could be subject to errors, which, if material, would result in a restatement of our financial statements. Restatements are generally costly and could adversely impact our results of operations, damage our reputation, and/or have a negative impact on the trading price of our common stock.[added] Our operating results may be adversely affected if our assumptions change or if actual circumstances differ from those in our assumptions, which could cause our operating results to fall below the expectations of securities analysts and investors, resulting in a decline in the trading price of our common stock.

Summary · quote-checked

The disclosure expands supplier dependence to other key components and adds gross-margin exposure, while removing the customer order rescheduling or cancellation risk.

The paragraph substantively changes the disclosed supply risks by broadening covered inputs, changing stated financial exposure, and dropping a customer-order risk.

Filing text · FY2024 10-K · filed Mar 3, 2025

[removed] Should any of our suppliers [removed] be acquired or become insolvent or capacity constrained, [removed] we may not be able to fulfill our customer orders, which would likely cause a decline in our revenue. While certain aspects of our relationships with these suppliers are contractual, many important aspects of our relationships depend on our suppliers' continued cooperation and our management of such relationships with the suppliers. Our relationships could be negatively impacted by changes in control or changes in the management team of the suppliers. In addition, the fabrication of ICs is a highly complex and precise process. Problems in the fabrication process can cause a substantial percentage of wafers to be rejected or numerous ICs on each wafer to be non-functional. This could potentially reduce yields and supply of our products. The failure of our suppliers to provide wafers at acceptable yields could prevent us from fulfilling our customer orders and would likely cause a decline in our revenue. In addition, adverse macroeconomic conditions, such as inflationary pressures resulting from worldwide supply chain constraints and other factors, have increased, and may continue to increase, the prices we pay to our suppliers. As a result of the increased costs, we have raised, and may be required to further raise the prices of our products in order to remain profitable, which could result in a loss of customers and reduced revenue. If we are unable to increase our prices to reflect higher costs, our margins will decrease.[removed] Further, as is common in the semiconductor industry, our customers may reschedule or cancel orders on relatively short notice. If our customers cancel orders after we submit a committed forecast to our suppliers for the corresponding wafers, we may be required to purchase wafers that we may not be able to resell, which would adversely affect our financial condition, results of operations and cash flows.

The paragraph replaces potential open-source litigation claims with specific license obligations and consequences affecting proprietary software and intellectual property.

Certain software we use is from [removed] open-source code sources, which, under certain circumstances, may lead to unintended consequences and, therefore, could materially adversely affect our business, financial condition, operating results and cash flows. We use [removed] open-source software in connection with certain of our products and services, and we intend to continue to use [removed] open-source software in the future. [removed] From time to time, there have been claims challenging the ownership of open-source software against companies that incorporate open-source software into their products or services or alleging that these companies have violated the terms of an open-source license. As a result, we could be subject to lawsuits by parties claiming ownership of what we believe to be open-source software or alleging that we have violated the terms of an open-source license. Litigation could be costly for us to defend, have a negative effect on our operating results and financial condition or require us to devote additional research and development resources to change our solutions. In addition, if we were to combine our proprietary software [removed] solutions with open-source software in certain circumstances, we could, under certain open-source licenses, be required to [removed] publicly release the [removed] source code of our [removed] proprietary software solutions, which could harm our business and ability to compete. If we inappropriately use open-source software, we may be required to re-engineer our solutions, discontinue the sale of our solutions, [removed] release the source code of our [removed] proprietary software to the public at no cost or take other remedial actions, which could increase our costs, harm our ability to compete and have a material adverse effect on our business, operating results and financial condition. There is also a risk that open-source licenses could be construed in a way that could impose unanticipated conditions or restrictions on our ability to commercialize our solutions, which could adversely affect our business, operating results and financial condition.

Summary · quote-checked

The risk discussion adds global tariffs as a potential manufacturing-cost factor and states that higher prices could reduce customer orders.

Global tariffs introduce a newly named cost driver, while the potential consequence expands from customer loss to declining orders; both substantively alter the stated risk.

Filing text · FY2024 10-K · filed Mar 3, 2025

These and other risks may affect the ultimate cost and timing of any expansion of our third-party supplier capacity.

Summary · quote-checked

The paragraph shifts from expecting semiconductor industry consolidation to continue to describing consolidation as historical.

Removing the explicit expectation of continued consolidation changes management’s stated outlook, rather than merely rephrasing the existing risk.

Filing text · FY2024 10-K · filed Mar 3, 2025

[removed] In recent years, there has been a trend toward semiconductor industry consolidation. We expect this trend to continue as companies attempt to improve the leverage of growing research and development costs, strengthen or hold their market positions in an evolving industry, or become unable to continue operations unless they find an acquirer or consolidate with another company. In addition, companies that are strategic alliance partners in some areas of our business may acquire or form alliances with our competitors, thereby reducing their business with us. We believe that semiconductor industry consolidation may result in stronger competitors that are better able to compete as sole-source suppliers of multiple products for customers. This could harm our operating results and could have a material adverse effect on our business, financial condition and results of operations.

Summary · quote-checked

The paragraph expands the supplier description and replaces named geopolitical conflicts with tariffs, retaliatory measures, and related announcements as macroeconomic factors.

The disclosure changes the described business scope and identifies different external risks, including tariffs and retaliatory measures; these are substantive changes rather than rephrasing.

Filing text · FY2024 10-K · filed Mar 3, 2025

Due to the nature of our business as a component supplier, we may have difficulty both in accurately predicting our future revenue and appropriately managing our expenses. Because we provide components for end products and systems, demand for our products is influenced by our customers' end product demand. As a result, we may have difficulty in accurately forecasting our revenue and expenses. Our expenses and revenue depend on the timing, size, and speed of commercial introductions of end products and systems that incorporate our products, all of which are inherently difficult to forecast, as well as the ongoing demand for previously introduced end products and systems. In addition, demand for our products is influenced by our customers' ability to manage their inventory. Our sales to distributors are also subject to higher volatility because they service demand from multiple levels of the supply chain which, in itself, is inherently difficult to forecast. All of these factors continue to be exacerbated by the adverse effects of macroeconomic factors, including inflation, increased interest rates, decreased economic output, fluctuations in currency rates, [removed] and geopolitical tensions, [removed] such as the Russia-Ukraine conflict and the Middle East conflict. If our customers reduce their orders from us, do not manage their inventory correctly or misjudge their customers' demand, our shipments to and orders from our customers may vary significantly or decline on a quarterly basis, and we may have difficulty forecasting our expenses and inventory levels, which could reduce our revenue or revenue opportunities, result in inventory write-offs, and adversely affect our financial condition and results of operations. We may be unsuccessful in developing and selling new products with margins similar to, or better than, what we have experienced in the past, which could impact our overall gross margin and financial performance. Our success depends on our development and sale of products that are differentiated in the market, with gross margins that have historically been above industry averages. Should we fail to improve or maintain our gross margins in the future, and accordingly develop and introduce sufficiently differentiated products that result in higher gross margins than industry averages or meet or exceed our historical margins, our business, financial condition and results of operations could be materially and adversely affected. We may be unsuccessful in developing and selling new products or in penetrating new markets required to maintain or expand our business. Our competitiveness and future success depend on our ability to design, develop, manufacture, assemble, test, market, and support new products and enhancements on a timely and cost-effective basis. A fundamental shift in technologies in any of our product markets could have a material adverse effect on our competitive position within these markets. Our failure to timely develop new technologies or to react quickly to changes in existing technologies could materially delay our development of new products, which could result in product obsolescence, decreased revenue, and/or a loss of market share to competitors. As we develop new product lines, we must adapt to market conditions that may be unfamiliar to us, such as competitors and distribution channels that are different from those we have known in the past. Some of our new product lines require us to re-equip our labs to test parameters we have not tested in the past. If we are unable to adapt rapidly to these new conditions, we may not be able to successfully penetrate new markets. The success of a new product depends on our ability to achieve design wins with key distributors and end-customers, as well as our ability to accurately forecast long-term market demand and future technological developments, as well as on a variety of other factors, including:

Summary · quote-checked

The risk disclosure removes reference to the new U.S. administration and adds potential supplier or supply-route changes if classifications are challenged.

Adding possible supplier or supply-route changes introduces a new operational dependency and response obligation, materially expanding the consequences of disagreement with the U.S. government.

Filing text · FY2024 10-K · filed Mar 3, 2025

We are subject to U.S. laws and regulations that could limit or restrict the export of some of our products, supplies and services and may restrict our transactions with certain customers, business partners and other individuals, including, in certain cases, dealings with or between us and our employees and subsidiaries. In certain circumstances, export controls and economic sanctions may prohibit the export of certain products, services and technologies, and in other circumstances we may be required to obtain an export license before exporting the controlled item. Compliance with these laws and regulations has not materially limited our operations or our sales, but could in the future, which would materially and adversely affect our business and results of operations. We maintain an export compliance program, but our compliance controls could be circumvented, exposing us to legal liabilities, sanctions and restrictions on our business. We must also comply with export restrictions and laws imposed by other countries affecting trade and investments. Although these restrictions and laws have not materially restricted our operations in the past, they could do so in the future, which would materially and adversely affect our business and results of operations. In addition, U.S. laws and regulations and sanctions, or threat of sanctions, that could limit or restrict the export of some of our products and services may also encourage our customers to develop their own solutions to replace our products, or seek to obtain a greater supply of similar or substitute products from our competitors that are not subject to these restrictions, which could materially and adversely affect our business, financial condition and results of operations. Furthermore, our customers' end products and systems that incorporate our components could be subject to export laws, trade policies and other sales restrictions, which could indirectly affect our business, financial conditions and results of operations. For example, the increasing focus on the risks and strategic importance of AI technologies has resulted in regulatory restrictions that target products and services capable of enabling or facilitating AI, and may in the future result in additional restrictions impacting the sales of AI technologies or products. Any of such regulatory restrictions could, in turn, impact the sales of our products supporting AI applications. There has been increasing rhetoric, in some cases coupled with legislative or executive action, from several U.S. and foreign leaders regarding tariffs against foreign imports of certain products and materials. Specifically, there have been several rounds of U.S. tariffs on Chinese goods that have taken effect in the past few years, as well as additional tariffs imposed by the new U.S. administration in January 2025, some of which prompted, and could prompt additional, retaliatory Chinese tariffs on U.S. goods. The institution of trade tariffs both globally and between the U.S. and China specifically carries the risk of negatively affecting both countries' overall economic condition, as well as our business and financial results. If these tariffs continue or additional tariffs are imposed in the future, they could have a negative impact on us as we have significant operations in China and the U.S. Additionally, the imposition of tariffs is dependent upon the classification of goods under the U.S. Harmonized Tariff System ("HTS") and the country of origin of the goods. Determination of the HTS and the origin of the goods is a technical matter that can be subjective in nature. Accordingly, although we believe our classifications of both HTS and origin are appropriate, there is no certainty that our assessment will be consistent with that of the U.S. [removed] government, particularly under the new U.S. administration. If the U.S. government does not agree with our determinations, we could be required to pay additional amounts, our ability to sell products in the U.S. may be restricted or [removed] eliminated and we may incur substantial additional costs or potential penalties.

While the U.S. administration has suspended the commencement of new investigations and enforcement actions under the FCPA, the FCPA remains in effect and it is uncertain whether enforcement actions and investigations will re-commence or whether the law will be changed or re-interpreted. [added] Moreover, non-U.S. enforcement authorities may continue investigations or actions irrespective of U.S. policy, resulting in multi-jurisdictional inquiries, duplicative penalties, or heightened remediation costs. Although we have implemented policies and procedures designed to ensure that we, our employees and other intermediaries comply with anti-corruption laws to which we are subject, there is no assurance that such policies or procedures will work effectively all the time or protect us against liability under these laws for actions taken by our employees and other intermediaries with respect to our business or any businesses that we may acquire. We have significant operations in Asia, which place us in frequent contact with individuals who may be considered "foreign officials" under the FCPA or other anti-corruption laws, resulting in an elevated risk of potential violations. If we are not in compliance with applicable anti-corruption laws (including local laws), we may be subject to criminal and civil penalties and other remedial measures, including restatements of our financial reports, which could have a material adverse impact on our business, financial condition, results of operations and liquidity. Any investigation or allegations of any potential violations of anti-corruption laws by the U.S. or foreign authorities could harm our reputation and have an adverse impact on our business, financial condition and results of operations.

The paragraph no longer states that the Chinese government provided semiconductor-industry incentives, limiting the stated incentive sources to provincial and local governments.

Removing the Chinese government changes the disclosed scope of governments providing incentives, which affects the stated dependency and potential exposure to incentive reductions or elimination.

Summary · quote-checked

The paragraph reordered the potential loss of revenue and customers and added that self-insurance could result in significant costs.

The added statement introduces a new cost consequence of self-insuring, changing the disclosed exposure beyond wording or restructuring.

Filing text · FY2024 10-K · filed Mar 3, 2025

Our customers generally establish demanding specifications for quality, performance, energy efficiency and reliability that our products must meet. ICs as complex as ours often encounter development delays and may contain undetected defects or failures when first introduced or after commencement of commercial shipments, which might require product replacement or recall. Further, our third-party manufacturing processes or changes thereto, or changes in the materials used in the manufacturing processes may cause our products to fail. From time to time, we have experienced product quality, performance or reliability problems. Our standard warranty period is generally one or two years, which exposes us to significant risks of claims for defects and failures. If defects and failures occur in our products, we could experience a loss of [removed] customers and/or a decrease in revenue, increased costs, including warranty expense and costs associated with customer support, cancellations or rescheduling of orders or shipments, and product returns or discounts, any of which would harm our operating results. In addition, product liability claims may be asserted by our customers. Although we currently have insurance, there can be no assurance that we have obtained sufficient insurance coverage or that asserted claims will be within the scope of coverage. Our insurance providers could deny or challenge these claims, and as a result, reimbursement to us is not guaranteed or could be delayed. If coverage is denied, we may not have sufficient resources to pay for these claims. Furthermore, we may experience a significant increase in premiums and therefore decide to self-insure, which may not meet the expectations or requirements of certain [removed] customers. All of these factors could have a material and adverse impact on our business, financial condition and results of operations.

The risk disclosure expands from intellectual property defenses to litigation or claims against the company and adds potential cessation of product sales.

The revised language broadens the legal scenarios covered and changes the potential consequence from ceasing production to ceasing production and sale, altering the stated business risk.

Filing text · FY2024 10-K · filed Mar 3, 2025

The semiconductor industry is characterized by frequent claims of infringement and litigation regarding patent and other intellectual property rights. Patent infringement is an ongoing risk, in part because other companies in our industry could have patent rights that may not be identifiable when we initiate development efforts. Litigation may be necessary to enforce our intellectual property rights, and we may have to defend ourselves, and in some circumstances our key customers or suppliers, against infringement claims. Such litigation is very costly. Further, in connection with these legal proceedings, we may be required to post bonds to defend our intellectual property rights in certain countries for an indefinite period of time, until such dispute is resolved.

Revenue from the automotive market increased $19.3 million, or [removed] 4.9%, from the same period in [removed] 2023. This increase was primarily driven by increased sales of our highly integrated applications supporting advanced driver assistance [removed] systems, partially offset by lower sales of applications supporting body electronics and infotainment. [removed] Revenue from the storage and computing market increased $10.4 million, or [removed] 2.1%, from the same period in [removed] 2023. This increase was primarily driven by increased sales of products for notebooks. Revenue from the consumer market decreased $32.6 million, or [removed] 13.9%, from the same period in [removed] 2023. This decrease was a result of [removed] broad market weakness. Revenue from the industrial market [removed] decreased $25.4 million, or [removed] 14.7%, from the same period in [removed] 2023.
