PART I

Item 1. Business

Overview

ON Semiconductor Corporation, together with its wholly and majority-owned subsidiaries, which operate under the onsemiTM brand ("onsemi," "we," "us," "our," or the "Company"), was incorporated under the laws of the State of Delaware in 1992.

We provide intelligent power and intelligent sensing solutions with a primary focus towards automotive and industrial markets to help our customers solve challenging problems and create cutting-edge products for a better future. We are utilizing our extensive range of power technologies to help address the growing power demands of AI and data centers. Our intelligent power technologies enable the electrification of the automotive industry that allows for lighter and longer-range electric vehicles, empowers efficient fast-charging systems and propels sustainable energy for the highest efficiency solar strings and industrial power. Our intelligent power solutions for the automotive industry allow our customers to exceed range targets with lower weight and reduce system cost through efficiency. Our intelligent sensing technologies support the next generation industry, allowing for smarter factories and buildings while also enhancing the automotive mobility experience with imaging and depth sensing that make advanced vehicle safety and automated driving systems possible.

We believe the evolution of the automotive industry, with advancements in autonomous driving, ADAS, vehicle electrification, and the increase in electronics content for vehicle platforms, is reshaping the boundaries of transportation. Through sensing integration, we believe our intelligent power solutions achieve superior efficiencies compared to our peers. This integration allows lower temperature operation and reduced cooling requirements while saving costs and minimizing weight. In addition, our power solutions deliver power with less die per module, achieving higher range for a given battery capacity.

As of December 31, 2024, we were organized into three operating and reportable segments: the Power Solutions Group ("PSG"), the Analog and Mixed-Signal Group ("AMG") and the Intelligent Sensing Group ("ISG"). During the first quarter of 2024, we reorganized the existing divisions within certain of our operating and reportable segments and renamed the Advanced Solutions Group ("ASG") reportable segment to AMG. See Note 3: ''Segments and Revenue'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for additional information regarding the segment reorganization.

Business Strategy Developments

Our primary focus continues to be on revenue growth with stable gross margin by capturing high-growth megatrends in our focused end-markets of automotive and industrial infrastructure. We design products in highly-differentiated markets focused on customer needs while optimizing and right-sizing our manufacturing footprint to support growth with new product development and maintain gross margins through efficiencies. We are focused on achieving efficiencies in our operating and capital expenditures, capital allocation on research and development investments and resources to accelerate growth in high-margin products.

2025 Acquisition

On January 14, 2025, we completed the previously announced acquisition of the Silicon Carbide Junction Field-Effect Transistor ("SiC JFET") technology business from Qorvo US, Inc., and certain of its subsidiaries, for $118.8 million in cash, subject to working capital adjustments. We believe the acquisition complements our EliteSiC power portfolio within the PSG reportable segment and enables us to help address the need for high energy efficiency and power density in the AC-DC stage in power supply units for AI data centers.

2024 Activities

2024 Business Realignment

In an effort to streamline resources, drive organizational efficiencies, consolidate our global corporate footprint, and align with our "Fab Right" manufacturing strategy, we continued our business realignment efforts during 2024. Under this plan, approximately 1,200 employees were notified of their employment termination and around 300 additional employees were reassigned or asked to relocate to another site. During the year ended December 31, 2024, we recorded severance costs, asset impairments and other related charges of approximately $75.7 million, $37.8 million and $16.3 million, respectively. See Note 7: ''Restructuring, Asset Impairments and Other Charges, net'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for additional information. We continue to evaluate employee positions and locations for

potential operating improvements and efficiencies.

Share Repurchases

During the year ended December 31, 2024, we repurchased approximately 9.1 million shares of our common stock for an aggregate purchase price of approximately $650 million, which excludes fees, commissions and excise taxes. See Note 10: ''Earnings Per Share and Equity'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for additional information.

2023 Activities

2023 Business Realignment

During 2023, we realigned our operating models in AMG (formerly "ASG"), Corporate information technology ("IT") organization and certain manufacturing locations in order to streamline our operations, achieve organizational efficiencies and consolidate resources into fewer, common sites across the world to align with the next phase of our multi-year "Fab Right" manufacturing strategy. Under this plan, approximately 1,900 employees were notified of their employment termination. We incurred severance costs and related charges of approximately $59.1 million related to these actions in 2023. See Note 7: ''Restructuring, Asset Impairments and Other Charges, net'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for additional information.

1.625% Notes maturity and repayment

On October 16, 2023, we repaid $119.6 million of the remaining outstanding principal amount of the 1.625% Notes in cash and settled the excess over the principal amount by issuing 4.5 million shares of our common stock. Under the previously executed bond hedge agreements, we also repurchased an equivalent number of shares of our common stock, for no additional consideration, to effectively offset the issuance of shares.

Credit Agreement

On June 22, 2023, we entered into a new Credit Agreement to replace the Revolver due 2024, which was set to mature on June 28, 2024. We drew $375.0 million against the Revolving Credit Facility and repaid the entire outstanding balance under the Revolver due 2024. We had previously repaid $125.0 million of the outstanding balance under the Revolver due 2024 during the first quarter of 2023.

0.50% Convertible Senior Notes due 2029

On February 28, 2023, we completed the offering of $1.5 billion aggregate principal amount of our 0.50% Notes and utilized the net proceeds along with cash generated from operations (i) to repay $1,086.0 million of the outstanding indebtedness under the Term Loan “B” Facility and the related transaction fees and expenses, (ii) to pay $171.5 million net cost of the related convertible note hedges after such costs were offset by the proceeds from the sale of warrants, and (iii) for general corporate purposes.

See Note 9: ''Long-Term Debt'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for additional information.

2022 Acquisitions and Divestitures

On December 31, 2022, we completed the acquisition of EFK along with certain other assets and liabilities from GLOBALFOUNDRIES U.S. Inc. ("GFUS") for total consideration of $406.3 million. We paid GFUS $236.3 million, $100.0 million and $70.0 million during 2023, 2020 and 2019, respectively.

During 2022, in line with our "Fab Right" strategy, we divested four wafer manufacturing facilities in Oudenaarde, Belgium, South Portland, Maine, Pocatello, Idaho and Niigata, Japan. We entered into wafer supply agreements with the respective buyers of these facilities to help minimize disruptions in our ability to meet customer demand for our products.

See Note 5: ''Acquisitions and Divestitures'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for additional information.

Competition

We face significant competition from major international semiconductor companies, as well as smaller companies focused on specific market niches. Because some of our components include functionality that in some cases may be integrated into more complex ICs, we also face competition from manufacturers of ICs, ASICs and fully-customized ICs, as well as customers who develop their own IC products. See "Risk Factors—Trends, Risks and Uncertainties Related to Our Business" included elsewhere in this Form 10-K for additional information.

Some of our competitors have greater financial and other resources to pursue development, engineering, manufacturing, marketing and distribution of their products and may generally be better situated to withstand adverse economic or market conditions. The semiconductor industry has experienced, and may continue to experience, significant consolidation among companies and vertical integration among customers. The following discusses the effects of competition on our three operating segments:

PSG

Our competitive strengths include core competencies such as leading-edge fabrication technologies, micro and module packaging expertise, breadth of product line and IP portfolio, high-quality, cost-effective manufacturing and supply chain management. Our commitment to continuous innovation allows us to provide a broad range of semiconductor solutions to our customers who differentiate in power density and power efficiency, the key performance characteristics driving our markets.

New products and package innovation that enable enhanced performance over existing portfolios drive competition. Of particular importance in the onsemi portfolio are the intelligent power technologies based on silicon and silicon carbide, wide band gap technologies, which we use to design, manufacture, and deliver to our customers as bare die, packaged discrete solutions or power module solutions. In addition to our power technologies, we believe our integrated circuit, signal and protection technologies have significant performance advantages over our competition.

All of our manufacturing facilities are fully owned and operated by us, except our assembly and test operations facility located in Leshan, China, which is owned by Leshan-Phoenix Semiconductor Company Limited, a joint venture company in which we own 80% of the outstanding equity interests ("Leshan"). The financial and operating results of Leshan have been consolidated in our financial statements. Our joint venture partner is Leshan Radio Company Ltd. ("Leshan Radio"), formerly a Chinese state-owned enterprise. Pursuant to the joint venture agreement between us and Leshan Radio, requests for production capacity are made to the board of directors of Leshan by each shareholder of the joint venture. Each request represents a purchase commitment, provided that any shareholder may elect to pay the cost associated with the unused capacity (which is generally equal to the fixed cost of the capacity) in lieu of satisfying the commitment. We purchased 80% of Leshan's production capacity in each of 2024, 2023 and 2022, and are currently committed to purchase approximately 80% of Leshan's expected production

capacity in 2025.

We use third-party contractors for some of our manufacturing activities, primarily for wafer fabrication and the assembly and testing of finished goods. Our agreements with these contract manufacturers typically require us to forecast product needs and commit to purchase services consistent with these forecasts. In some cases, longer-term commitments are required in the early stages of the relationship. These manufacturers collectively accounted for approximately 33% of our total manufacturing input costs in 2024, 36% in 2023 and 43% in 2022.

For information regarding risks associated with our foreign operations, see "Risk Factors — Trends, Risks and Uncertainties Related to Our Business" included elsewhere in this Form 10-K.

Patents, Trademarks, Copyrights and Other Intellectual Property Rights

We market our products under worldwide trademarks, including the ON Semiconductor, ON, onsemi, and various product names and logos, and, in the United States and internationally, we rely primarily on a combination of patents, trademarks, copyrights, trade secrets, employee and non-disclosure agreements and licensing agreements to protect our IP. We acquired, licensed or sublicensed a significant amount of IP, including patents and patent applications, in connection with our acquisitions, and we have numerous United States and foreign patents issued, allowed and pending. We do not consider our business substantially dependent on any single onsemi patent. Our policy is to protect our products and processes by asserting our IP rights where appropriate and prudent and by obtaining patents, copyrights and other IP rights used in connection with our business when practicable and appropriate. We believe the duration of our IP rights is adequate to protect our products and processes.

For information regarding risks associated with intellectual property, see "Risk Factors — Trends, Risks and Uncertainties Related to Intellectual Property" included elsewhere in this Form 10-K.

Seasonality

We are currently experiencing fluctuations in our operating results due to general industry and macroeconomic conditions as well as within the semiconductor industry. However, we believe our business is driven more by content gains within applications and secular growth drivers and not solely by macroeconomic and industry cyclicality. For information regarding risks associated with the cyclicality and seasonality of our business, see "Risk Factors—Trends, Risks and Uncertainties Related to Our Business" included elsewhere in this Form 10-K.

Government Regulation

Our manufacturing operations are subject to various United States and foreign environmental and worker health and safety laws and regulations. These laws and regulations include those relating to emissions and discharges into the air and water, the management and disposal of hazardous substances, the release of hazardous substances into the environment at or from our facilities and at other sites and the investigation and remediation of contamination. As with other companies engaged in like businesses, the nature of our operations exposes us to the risk of liabilities and claims, regardless of fault, with respect to such matters, including personal injury claims and civil and criminal fines.

We believe that our operations are in material compliance with applicable environmental and health and safety laws and regulations. The costs we incurred in complying with applicable environmental regulations for the year ended December 31, 2024 were not material, and we do not currently expect the cost of complying with existing environmental and health and safety laws and regulations, together with any liabilities for currently known environmental conditions, to have a material adverse effect on our capital expenditures or earnings or on our competitive position in any one year. It is possible, however, that future developments, including changes in laws and regulations, government policies, customer specification, personnel and physical property conditions, including currently undiscovered contamination, could lead to material costs, and such costs may have a material adverse effect on our future business or prospects. See Note 13: ''Commitments and Contingencies'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for information on certain environmental matters.

We are also subject to numerous United States and foreign laws and regulations, including, without limitation, tariffs, trade sanctions, trade barriers, trade embargoes, regulations relating to import-export control, technology transfer restrictions, the International Traffic in Arms Regulation promulgated under the Arms Export Control Act ("ITAR"), the Foreign Corrupt Practices Act ("FCPA"), and the anti-boycott provisions of the U.S. Export Administration Act. Additionally, United States and foreign governmental authorities have taken, and may continue to take, administrative, legislative or regulatory action that

could impact our operations.

We believe that our operations are in material compliance with applicable trade regulations relating to import-export control, technology transfer restrictions, ITAR, FCPA, the anti-boycott provisions of the U.S. Export Administration Act, and similar applicable laws and regulations. The costs we incurred in complying with applicable trade regulations for the year ended December 31, 2024 were not material, and we do not currently expect the cost of complying with existing trade laws and regulations to have a material adverse effect on our capital expenditures or earnings or on our competitive position in any one year. It is possible, however, that future developments, including changes in laws and regulations or government policies, could lead to material costs, and such costs may have a material adverse effect on our future business or prospects. For information regarding risks associated with import-export control regulations and similar applicable laws and regulations, see "Risk Factors—Trends, Risks and Uncertainties Related to Our Business" included elsewhere in this Form 10-K.

Environmental, Social and Governance Initiatives

onsemi strives to be a responsible corporate citizen. We uphold ethical standards in our business practices and policies, and we believe that sustainable corporate practices and consistent attention to environmental, social and governance priorities will help enhance long-term value for our stockholders.

onsemi strives to protect and respect its environment and energy resources for future generations throughout its operations, including wafer fabrication, assembly, test, support operations, and through its value chain. We have a goal to achieve net zero emissions by 2040, supported by our climate change policy, which highlights the focus areas for climate change-related actions. In 2024, our near-term greenhouse gas emissions targets were validated by the Science Based Targets initiative. We have formulated a strategy and are taking initial steps towards the achievement of our targets.

We work together with our customers, peers, partners and suppliers to promote continual improvement in human rights, labor, environment, health and safety, anti-corruption, ethics and management system standards within our operations and our supply chain. We proactively comply with the Responsible Business Alliance (“RBA”) Code of Conduct, which is aimed at eliminating forced labor, slavery and human trafficking and conflict minerals, pursuant to our involvement with the Responsible Minerals Initiative.

Our Board of Directors (the "Board of Directors" or the "Board") and management regularly evaluate our corporate responsibility policies, including our Code of Business Conduct and other corporate social responsibility policies and programs, to help ensure an effective outcome and adherence by our employees, suppliers, vendors and partners.

Human Capital Resources

Core Principles

Our success depends on our ability to attract, train, retain and motivate our employees involved in the design, development, manufacturing and support of new and existing products and services. We value the diversity of our workforce and work consciously to create growth and development opportunities for our employees, embracing different perspectives and fostering an inclusive work environment. As we are a member of the RBA, its principles are fundamental to our corporate culture and core values and are reflected in our commitments to our employees, customers, communities and other stakeholders. These principles include providing a safe and positive work environment for our employees that emphasizes learning, professional development and respect for individuals and ethical conduct.

Headcount

As of December 31, 2024, we had approximately 26,400 regular full-time employees and approximately 90 part-time and temporary employees in facilities located in 33 countries. Approximately 15% of our regular full-time employees are located in the United States and Canada, 12% in Europe and Middle Eastern countries and 73% in Asia Pacific and Japan, with approximately 72% engaged in manufacturing, 2% in research and development, 4% in customer service or other aspects of sales and marketing, and 22% in other roles. Approximately 230 of our domestic employees (or approximately 1% of our United States-based employees) are covered by a collective bargaining agreement, and all of these employees are located at our Mountain Top, Pennsylvania manufacturing facility. Certain of our foreign employees are covered by collective bargaining arrangements (e.g., those in China, Vietnam, Japan, the Czech Republic and Belgium) or similar arrangements or are represented by workers councils.

Compensation, Benefits, Health, Safety and Wellness

Our compensation philosophy is focused on delivering competitive compensation with total rewards based on corporate affordability in a way that enables attraction, retention, and recognition of performance. We provide our employees and their families with access to flexible and convenient health and wellness programs, including benefits that secure them during events that may require time away from work or that impact their financial well-being. We use a combination of total rewards and other programs (which vary by region and salary grade) to attract and retain our employees, including: annual performance bonuses; stock awards, including an employee stock purchase plan; retirement support; healthcare and insurance benefits; business travel and disability insurance; health savings and flexible spending accounts; flexible work schedules, vacation and paid time off; parental leave; paid counseling assistance; education assistance; and on-site services, such as health centers and fitness centers.

Career Growth and Development

We invest resources in professional development and growth as a means of improving employee motivation, performance and retention. Our talent development programs provide employees with the resources they need to help achieve their career goals, build management skills and lead their organizations. We have established a leadership pathway model as a tool for employees to practice and apply learning as part of their development.

Turnover

We monitor employee turnover rates by region and globally. The average tenure of our employees is approximately 11 years and approximately 42% of our employees have been employed by us for more than ten years. We believe our compensation philosophy, along with the career growth and development opportunities we offer, promotes longer employee tenure and reduces voluntary turnover.

Trends, Risks and Uncertainties Related to Our Business

The manufacturing and other operations required to produce our products are highly dependent on the efficient operation of numerous processes, including processes contingent upon third-party component manufacturers and other service providers, and any disruption in these processes could have a material adverse effect on our business and results of operations.

Our manufacturing network includes multiple owned and third-party facilities, which may each produce one or more components necessary for the assembly of a single product. As a result of this interdependence, an operational disruption at a facility may have a disproportionate impact on our ability to produce many of our products. In the event of a disruption at any such facility, we may be unable to effectively source replacement components on acceptable terms from qualified third parties, in which case our ability to produce many of our products could be materially disrupted or delayed. Conversely, some of our facilities are single source facilities that only produce one of our end-products, and a disruption at any such facility would materially delay or cease production of the related product. In the event of any such operational disruption, we may experience difficulty in beginning production of replacement components or products at new facilities or transferring production to other existing facilities, any of which could result in a loss of future revenues and materially adversely affect our business and results of operations.

In addition, for certain manufacturing activities and for the supply of raw materials, we utilize third-party suppliers. Our agreements with these manufacturers typically require us to commit to purchase services based on forecasted product needs, which may be inaccurate, and, in some cases, require longer-term commitments. We are also dependent upon a limited number of highly specialized third-party suppliers for required components and materials for certain of our key technologies. Arranging for replacement manufacturers and suppliers can be time-consuming and costly, and the number of qualified alternative providers can be extremely limited. Our business operations, productivity and customer relations could be materially adversely affected if these contractual relationships were disrupted or terminated, the cost of such services increased significantly, the quality of the services provided deteriorated or our forecasted needs proved to be materially incorrect. Generally, our agreements with suppliers of raw materials impose no minimum or continuing supply obligations, and we obtain our raw materials and supplies from a large number of sources. Shortages could occur in various essential raw materials, and if we are unable to obtain adequate supplies of raw materials in a timely manner, the costs of our raw materials increase significantly, their quality deteriorates or they give rise to compatibility or performance issues in our products, our results of operations could be materially adversely affected.

Our manufacturing efficiency is contingent upon the operations of these interdependent processes and will continue to be an important factor in our future profitability, and there can be no assurance that we will be able to maintain our manufacturing efficiency, increase our manufacturing efficiency to the same extent as our competitors, or be successful in our manufacturing rationalization plans. For example, public health crises may cause disruption to our domestic and international operations. Any associated worker absenteeism, quarantines and restrictions on certain of our employees’ ability to perform their jobs, office

and factory closures or restrictions, labor shortages, disruptions to ports and other shipping infrastructure, border closures and/or other travel or health-related restrictions could, depending on the magnitude of such effects on our manufacturing activities (or activities of our suppliers, third-party distributors or sub-contractors), cause disruption and delay to our supply chain, manufacturing and product shipments. Such disruption and delays could materially adversely affect our business, results of operations and financial condition.

In addition, if we are unable to utilize our manufacturing facilities, testing facilities and external manufacturers at expected or minimum purchase obligation levels, or if production capacity increases while revenue does not, the fixed costs and other operating expenses associated with these facilities and arrangements will not be fully absorbed, resulting in higher average unit costs and lower gross profits, which could have a material adverse effect on our results of operations. Further, if we need to rapidly increase our business and manufacturing capacity to meet increases in demand or expedited shipment schedules, this could strain our manufacturing and supply chain operations, and negatively impact our working capital. Moreover, if we are unable to accurately forecast demand for our products, we may purchase more or fewer parts than necessary or incur costs for canceling, postponing or expediting delivery of parts. If we purchase or commit to purchase inventory in anticipation of customer demand that does not materialize, or such inventory is rendered obsolete by the rapid pace of technological change, or if customers reduce, delay or cancel orders, we may incur excess or obsolete inventory charges.

We may be unable to implement certain business strategies and restructuring initiatives and any issue with the pursuit of such strategies and initiatives could materially adversely affect our business and results of operations.

We may from time to time determine to implement business strategies and restructuring initiatives in order to remain competitive. Because our strategies and restructuring activities may involve changes to many aspects of our business, including the location of our production facilities and personnel and the potential exit of certain product lines and businesses, our ability to successfully do so depends on a number of factors, many of which are outside of our control. If we are not able to effectively manage or efficiently implement these strategies and/or restructuring initiatives for reasons within or outside of our control, then our business operations could be materially adversely affected.

In addition, implementation of a business strategy may lead to the disruption of our existing business operations. For example, in light of our goal to achieve net zero emissions by 2040, we may take actions to pursue our goal of generating net-zero emissions that may result in material expenditures that could impact our financial condition or results of operations and/or could disrupt our existing operations. Similarly, the contingent risks associated with transferring our existing operations to an acquirer, as is the case with several transition services being provided in connection with some of our prior divestitures, could materially impact our financial condition or results of operations and/or could disrupt our existing operations, especially if the acquirer is unable to meet its commitments under any transition services agreements or if the acquirer encounters financial difficulty. Furthermore, our increased investment in manufacturing capacity (including increased investment in capacity for SiC-based products and technology), while concurrently divesting other non-strategic operations, may adversely impact our existing operations, require additional management time and effort to implement successfully, and lead to higher than anticipated capital expenditures.

In relation to production of SiC-based products and manufacturing at EFK and at our facilities in Hudson, New Hampshire, the Czech Republic and South Korea, we may face challenges or risks related to: increased capital spending and long-term capital expenditure commitments, installing and qualifying new manufacturing equipment, meeting planned process yields, maintaining suitable quality control and educating or providing employees with the requisite know-how to operate the processes at our expanded manufacturing facilities. There are inherent execution risks in expanding production capacity, whether at one of our own factories or at a third party that we utilize, all of which could increase our costs and negatively impact our operating results.

In addition, to streamline our operations and for efficiency purposes, we are pursuing a number of actions, including the outsourcing of certain internal business processes and the deployment of enhanced end-to-end digital processes (which, in some cases, include the use of AI) for certain business use cases. Such opportunities for improvement and enhanced productivity bring risks associated with managing change, transition costs, and the potential for reduced productivity or user error, in addition to those risks specific to each new process.

The failure to successfully and timely realize the anticipated benefits of these transactions or strategies could have a material adverse effect on our profitability, financial condition or results of operations. In addition, even if we fully execute and implement these activities, there may be other unforeseeable and unintended consequences that could materially adversely impact our profitability and business, including unintended employee attrition or harm to our competitive position. To the extent that we do not achieve the profitability enhancement or other anticipated benefits of strategy or restructuring initiatives, our results of operations may be materially adversely affected.

If we are unable to identify and make the substantial research and development investments or develop new products required to satisfy customer demands, our business, financial condition and results of operations may be materially adversely affected.

The semiconductor industry requires substantial investment in research and development in order to develop and bring to

market enhanced technologies and products. The development of new products is complex and time-consuming, often requiring significant capital investment and lead time for development and testing. We cannot assure you that we will have sufficient resources to maintain the level of investment in research and development required to remain competitive. In addition, the lengthy development cycle for certain of our products could limit our ability to adapt quickly to changes affecting the product markets and requirements of our customers and end-users, and we may be unable to develop innovative responses to our customers’ and end-users’ evolving needs on the timelines they require or at all. There can be no assurance that we will win competitive bid selection processes, known as "design wins," for new products. In addition, design wins do not guarantee that we will make customer sales or generate sufficient revenue to recover design and development investments, realize a return on the capital expended or achieve expected gross margins, as expenditures for technology and product development are generally made before the commercial viability for such developments can be assured. To the extent that we underinvest in our research and development efforts, fail to recognize the need for innovation with respect to our products, or our investments and capital expenditures in research and development do not lead to sales of new products, we may be unable to bring to market technologies and products attractive to customers, and so our business, financial condition and results of operations may be materially adversely affected. Further, products that are commercially viable may not have an immediate impact on our revenue or contribute to our operating results in a meaningful way until at least a few years after they are introduced into the market.

The semiconductor industry is characterized by rapidly evolving technologies, innovation, short product life cycles, evolving regulatory and industry standards and certifications, changing customer needs, wide fluctuations in supply and demand and frequent new product introductions. Products are often replaced by more technologically advanced substitutes and, as demand for older technology falls, the price at which such products can be sold drops. If we cannot advance our process technologies or improve our production efficiencies to a degree sufficient to maintain required margins, we will no longer be able to make a profit from the sale of older products. In certain limited cases, we may not be able to cease production of older products, either due to contractual obligations or for customer relationship reasons and, as a result, may be required to bear a loss on such products for a sustained period of time. If reductions in our production costs fail to keep pace with reductions in market prices for products we sell, our business and results of operations could be materially adversely affected. If our new product development efforts fail to align with the needs of our customers, our business and results of operations could be materially adversely affected.

The semiconductor industry is highly competitive, and has experienced significant consolidation, and if we are unable to compete effectively or identify attractive opportunities for consolidation, it could materially adversely affect our business and results of operations.

Our ability to compete successfully in the highly competitive semiconductor industry depends on elements both within and outside of our control. We face significant competition within each of our product lines from major global semiconductor companies as well as smaller companies focused on specific market niches. In addition, companies not currently in direct competition with us may introduce competing products in the future.

If we are unable to compete effectively, our competitive position could be weakened relative to our peers, which would have a material adverse effect on our business and results of operations. Our future success depends on many factors, including the development of new technologies and effective commercialization and customer acceptance of our products, and our ability to increase our position in current markets, expand into adjacent and new markets, and optimize operational performance. Products or technologies developed by competitors may render our products or technologies obsolete or noncompetitive. We also may be unable to market and sell our products if they are not competitive on the basis of price, quality, technical performance, features, system compatibility, ease of use, customized design, innovation, availability, delivery timing and reliability. If we fail to compete effectively on developing strategic relationships with customers and customer sales and technical support, our sales and revenue may be materially adversely affected. Competitive pressures may limit our ability to raise prices, and any inability to maintain revenue or raise prices to offset increases in costs could have a significant adverse effect on our gross margin. Our gross margins vary due to a variety of factors. Reduced sales and lower gross margins would materially adversely affect our business and results of operations.

The semiconductor industry has experienced, and may continue to experience, significant consolidation among companies and vertical integration among customers. Larger competitors resulting from consolidations may have certain advantages over us, and we may be at a competitive disadvantage if we fail to identify attractive opportunities to acquire companies to expand our business. Consolidation among competitors and integration among customers could erode our market share, impair our capacity to compete and require us to restructure operations, any of which could have a material adverse effect on our business.

In addition, some of our competitors may receive governmental subsidies or other incentives that give them a competitive advantage over us. For example, the United States and the European Union have enacted legislation to provide funding and incentives for semiconductor research, development, and manufacturing in their respective regions. If we are unable to access such funding or incentives, or if our competitors receive more funding or incentives than we do, we may be at a disadvantage in developing and producing new or improved products or technologies, which could adversely affect our market share, revenue

and profitability.

Because a significant portion of our revenue is derived from customers in the automotive and industrial end-markets, including revenue pursuant to our long-term supply agreements, a downturn or lower sales to customers in either end-market could materially adversely affect our business and results of operations.

A significant portion of our sales are to customers within the automotive industry and the industrial sector and the demand for our products depends in part on the market conditions in these end-markets. Sales into the automotive and industrial end-markets represented approximately 55% and 25% of our revenue, respectively, for the year ended December 31, 2024. The automotive industry is cyclical and the industrial sector tends to thrive during a time of economic expansion, and, as a result, our customers in each end-market are sensitive to changes in general economic conditions, inflationary pressure, increases in interest rates, disruptive innovation and end-market preferences, which can adversely affect sales of our products and, correspondingly, our results of operations. Changes in demand in these end-markets or changes that have the potential to disrupt sales activities to customers in these end-markets, can significantly impact our operating results. Additionally, the quantity and price of our products sold to customers in each end-market could decline despite continued growth in such end-markets. Lower sales to customers in either end-market may have a material adverse effect on our business and results of operations.

Further, to the extent we have long-term supply agreements with our customers in multiple end-markets which includes fixed pricing, we could be subject to fluctuating manufacturing costs that could negatively impact our profitability. Additionally, under our long-term supply agreements, we could incur certain obligations if we are not able to fulfill our commitments. Furthermore, certain customers, from time to time, have sought and may seek to amend or cancel the delivery or other terms of their long-term supply agreements with us. When any such contractual amendments are made, the timing, pricing or amount of products delivered under such long-term supply agreements may be modified in circumstances where we believe it advances the long-term customer relationship. Such an event could have an impact on our results of operations.

Our operating results depend, in part, on the performance of independent distributors.

A portion of our sales occurs through global and regional distributors that are not under our control. We rely on distributors to grow and develop their customer base and anticipate customer needs, and any lack of such actions by our distributors may adversely affect our results of operations. These independent distributors also generally represent product lines offered by several companies and are not subject to any minimum sales requirements or obligation to market our products to their customers. In turn, distributors could reduce their sales efforts for our products or choose to terminate their representation of us. In addition, in the event a distributor were to face financial difficulty, experience significant operational disruptions or terminate its operations, our revenue and results of operations may be adversely affected. Furthermore, if a significant distributor terminates its operations or were to merge with another distributor, we may be more reliant and dependent on the distribution network of our remaining distributors. Additionally, we rely on our distributors to provide accurate and timely sales reports in order for us to be able to generate financial reports that accurately represent distributor sales of our products during any given period. Any inaccuracies or untimely reports could adversely affect our ability to produce accurate and timely financial reports and recognize revenue.

Changes in, and the regulatory implementation of, tariffs or other government trade policies or political conditions could reduce demand for our products, limit our ability to sell our products to certain customers or our ability to comply with applicable laws and regulations, which may materially adversely affect our business and results of operations.

The imposition of or increase in tariffs, export controls and other trade restrictions as a result of international trade disputes or changes in trade policies or political conditions may adversely affect our sales and profitability. For example, a significant trade disruption, additional tariffs, trade protection measures, export or import regulations or other restrictions imposed related to our business and the related geopolitical uncertainty between the United States, China, Canada, Mexico and other countries or any retaliatory actions from such governments could have a material adverse effect on our business and results of operations.

More specifically, our assembly and test operations facility located in Leshan, China, which is owned by Leshan-Phoenix Semiconductor Company Limited, a joint venture company in which we own 80% of the outstanding equity interests, may be subjected to increased costs or additional trade restrictions stemming from the geopolitical tension between the United States and China. The U.S. Department of Commerce could in the future add additional Chinese companies to its restricted entity list or unverified list or take other actions that could expand licensing requirements or otherwise impact the market for our products and our revenue. These rules may require us to apply for and obtain additional export licenses to supply certain of our products to customers in China, and there is no assurance that we will be issued licenses that we apply for on a timely basis or at all. Additional tariffs, export controls or other trade restrictions between the two countries could materially adversely affect our results of operations.

In addition, tariffs on components that we import from certain nations that have imposed, or may in the future impose, tariffs may adversely affect our profitability unless we are able to exclude such components from the tariffs or we raise prices for our products, which may result in our products becoming less attractive relative to products offered by our competitors. To the extent that our sales or profitability are negatively affected by any such tariffs or other trade actions, our business and results of

operations may be materially adversely affected.

Our international sales and purchases are subject to numerous additional United States and foreign laws and regulations related to import and export matters. For example, licenses or proper license exceptions are required for the shipment of our products to certain countries under applicable export control regulations, including the provisions of the U.S. Export Administration Act. A determination by the United States government or any foreign government that we have failed to comply with trade or export regulations can result in penalties, including fines, administrative, civil or criminal penalties or other liabilities, seizure of products, or, in the extreme case, denial of export privileges or suspension or debarment from government contracts, which could have a material adverse effect on our sales, business and results of operations.

Our power technologies used for AI may not capture market share as expected, and issues related to the responsible use of AI may adversely affect our business.

Our extensive range of power technologies are used to help power AI and related data centers and we expect this part of our business to grow. The emergence of big data and new tools such as machine learning and AI that capitalize on the availability of large data sets is leading semiconductor manufacturers to pursue new products and approaches, and there is an intense competition to capture market share in this emerging market. We may not be able to develop and offer the technology solutions that our AI-focused customers demand in a timely manner or effectively, which could have a materially adverse effect on our business. Our failure to commercialize new technologies that can power AI and data centers in a timely manner or at all could result in loss of market share, unanticipated costs, and inventory obsolescence, which could adversely affect our financial results.

As with many new emerging technologies, AI presents risks and challenges and increasing legal, social and ethical concerns relating to its responsible use that could affect the adoption of AI. Third-party misuse of AI applications, models, or solutions, or ineffective or inadequate AI development or deployment practices by our customers could cause harm to individuals or society and impair the public’s acceptance of AI, which would in turn adversely affect our business.

We may be unable to attract and retain highly skilled personnel.

Our success depends on our ability to attract, motivate and retain highly skilled personnel, including technical, marketing, management and staff personnel, both in the United States and internationally. In the semiconductor industry, the competition for qualified personnel, particularly experienced design engineers and other technical employees, is intense. Furthermore, we have operations in many parts of the world that are currently experiencing a tight labor market for skilled employees. Additionally, we have entered into employment agreements with certain senior executives, but we do not have employment agreements with most of our employees. Many of these employees could leave our company with little or no prior notice and would be free to work for a competitor. Specific elements of our compensation programs may not be competitive with those of our competitors, and there can be no assurance that we will be able to retain our current personnel or recruit the key personnel we require. If one or more of our senior executives or other key personnel are unable or unwilling to continue in their present positions, we may not be able to replace them easily or at all and other senior management may be required to divert attention from other aspects of our business. Loss of the services of, or failure to effectively recruit, qualified personnel could have a material adverse effect on our competitive position and on our business.

Warranty claims, product liability claims, product recalls, and the failure to comply with the terms and conditions of our contracts, could harm our business, reputation, results of operations and financial condition.

Manufacturing semiconductors is a highly complex and precise process, requiring production in a tightly controlled, clean environment. Minute impurities in our manufacturing materials, contaminants in the manufacturing environment, manufacturing equipment failures, and other defects can cause our products to be non-compliant with customer requirements or otherwise nonfunctional. We face an inherent business risk of exposure to warranty and product liability claims in the event that our products fail to perform as expected or such failure of our products results, or is alleged to result, in bodily injury or property damage (or both). In addition, if any of our designed products are or are alleged to be defective, we may be required to participate in their recall. As suppliers become more integrally involved in electrical design, OEMs are increasingly expecting them to warrant their products and are looking to them for contributions when faced with product liability claims or recalls. A successful warranty or product liability claim against us in excess of our available insurance coverage, if any, and established reserves, or a requirement that we participate in a product recall, could have material adverse effects on our business, results of operations and financial condition. 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 adversely affect our business, reputation, results of operations and financial condition. Even if our products meet standard specifications, our customers may attempt to use our products in applications for which our products were not designed or in customer products that were not designed or manufactured properly, resulting in product failures and creating customer satisfaction issues, which may harm our reputation.

Since a defect or failure in our products could give rise to failures in the goods that incorporate them (and claims for consequential damages against our customers from their customers), we may face claims for damages that are disproportionate to the revenue and profits we receive from the products involved. In certain instances, we attempt to limit our liability through our standard terms and conditions or other contractual provisions, but there is no assurance that such limitations will be effective. To the extent we are liable for damages in excess of the revenue and profits received from the products involved, our results of operations and financial condition could be materially adversely affected.

Currency fluctuations, changes in foreign exchange regulations and repatriation delays and costs could have a material adverse effect on our results of operations and financial condition.

We have sizeable sales and operations in the Asia/Pacific region and Europe, and a significant amount of this business is transacted in currency other than U.S. dollars. In addition, while a significant percentage of our cash is generated outside the United States, many of our liabilities, including our outstanding indebtedness, and certain other cash payments, such as share repurchases, are payable in the United States in U.S. dollars. As a result, currency fluctuations and changes in foreign exchange regulations can have a material adverse effect on our liquidity and financial condition.

In addition, repatriation of funds held outside the United States could have adverse tax consequences and could be subject to delay due to required local country approvals or local obligations. Foreign exchange regulations may also limit our ability to convert or repatriate foreign currency. As a result of having a lower amount of cash and cash equivalents in the United States, our financial flexibility may be reduced, which could have a material adverse effect on our ability to make interest and principal payments due under our various debt obligations. Restrictions on repatriation or the inability to use cash held abroad to fund our operations in the United States may have a material adverse effect on our liquidity and financial condition.

Trends, Risks and Uncertainties Related to Intellectual Property

If our technologies are subject to claims of infringement on the IP rights of others, efforts to address such claims could have a material adverse effect on our results of operations.

We may from time to time be subject to claims that we may be infringing the IP rights of others. If necessary or desirable, we may seek licenses under such IP rights. However, we cannot assure you that we will obtain such licenses or that the terms of any offered licenses will be acceptable to us. The failure to obtain a license from a third party for IP we use could cause us to incur substantial liabilities or to suspend the manufacture or shipment of products or our use of processes requiring such technologies. Further, we may be subject to IP litigation, which could cause us to incur significant expense, materially adversely affect sales of the challenged product or technologies and divert the efforts of our technical and management personnel, whether or not such litigation is resolved in our favor. In the event of an adverse outcome or pursuant to the terms of a settlement of any such litigation, we may be required to: pay substantial damages or settlement costs; indemnify customers or distributors; cease the manufacture, use, sale or importation of infringing products; expend significant resources to develop or acquire non-infringing technologies; discontinue the use of certain processes; or obtain licenses, which may not be available on reasonable terms, to continue the use, development and/or sale of the allegedly infringing technologies.

The outcome of IP litigation is inherently uncertain and, if not resolved in our favor, could materially adversely affect our business, financial condition and results of operations.

If we are unable to protect the IP we have developed or licensed, our competitive position, business and results of operations could be materially and adversely affected.

The enforceability of our patents, trademarks, copyrights, software licenses and other IP is uncertain in certain circumstances. Effective IP protection may be unavailable, limited or not applied for in the United States and internationally. The various laws and regulations governing our registered and unregistered IP assets, patents, trade secrets, trademarks, mask works and copyrights to protect our products and technologies are subject to legislative and regulatory change and interpretation by courts. With respect to our IP generally, we cannot assure you that:

•any of the substantial number of United States or foreign patents and pending patent applications that we employ in our business will not lapse or be invalidated, circumvented, challenged, abandoned or licensed to others;

•any of our pending or future patent applications will be issued or have the coverage originally sought;

•any of the trademarks, copyrights, trade secrets, know-how or mask works that we employ in our business will not lapse or be invalidated, circumvented, challenged, abandoned or licensed to others;

•any of our pending or future trademark, copyright, or mask work applications will be issued or have the coverage originally sought; or

•that we will be able to successfully enforce our IP rights in the United States or foreign countries.

Infringement or misappropriation of our IP could result in lost market and revenue opportunities, and if we are unable to enforce and protect our IP it could have an adverse impact on our competitive position and business. Further, our assertion of IP rights often results in the other party seeking to assert alleged IP rights of its own against us, which may materially and

adversely impact our business. An unfavorable ruling in these sorts of matters could include money damages or an injunction prohibiting us from manufacturing or selling one or more products, which could in turn negatively affect our business, results of operations or cash flows.

In addition, some of our products and technologies are not covered by any patents or pending patent applications. We seek to protect our proprietary technologies, including technologies that may not be patented or patentable, in part by confidentiality agreements and, if applicable, inventors’ rights agreements with our collaborators, advisors, employees and consultants. We cannot assure you that these agreements will not be breached, that we will have adequate remedies for any breach or that persons or institutions will not assert rights to IP arising out of our research. Should we be unable to protect our IP, competitors may develop products or technologies that duplicate our products or technologies, benefit financially from innovations for which we bore the costs of development and undercut the sales and marketing of our products, all of which could have a material adverse effect on our business and results of operations.

Trends, Risks and Uncertainties Related to Technology and Data Privacy

Disruptions or breaches of our information technology systems could irreparably damage our reputation and our business, expose us to liability and materially adversely affect our results of operations.

We routinely collect and store sensitive data, including confidential and other proprietary information about our business and our employees, customers, suppliers and business partners. The secure processing, maintenance and transmission of this information is important to our operations and business strategy. We have experienced and expect to continue to experience disruptions, failures or breaches of our information technology environment, such as those caused by computer viruses, illegal hacking, criminal fraud or impersonation, acts of vandalism or terrorism or employee error. Our cybersecurity measures and/or those of our third-party service providers and/or customers may not detect or prevent such security breaches. Although we are not aware of any cybersecurity incidents that have materially affected or are reasonably likely to materially affect our business as of the year ended December 31, 2024, we continue to devote resources to reduce the risk of or alleviate cybersecurity breaches and vulnerabilities and those costs could be significant. Although we maintain a cybersecurity program to manage cybersecurity risks, our efforts may not be successful and could result in interruptions and delays that may materially impede our sales, manufacturing operations, distribution or other critical functions. Any 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 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. Further, AI capabilities may be used to identify vulnerabilities and craft increasingly sophisticated cybersecurity attacks. Any of the foregoing could irreparably damage our reputation and business, which could have a material adverse effect on our results of operations. We maintain cyber risk insurance, although an insufficiency of insurance coverage could adversely affect our cash flows and overall profitability. Furthermore, our efforts to comply with evolving laws and regulations related to cybersecurity may be costly and any failure to comply could result in investigations, proceedings, investor lawsuits and reputational damage.

We are subject to governmental laws, regulations and other legal obligations related to privacy and data protection.

The legislative and regulatory framework for privacy and data protection issues worldwide is rapidly evolving and is likely to remain uncertain for the foreseeable future. We collect Personally Identifiable Information ("PII") and other data as part of our business processes and activities. This data is subject to a variety of laws and regulations, including oversight by various regulatory or other governmental bodies. Many foreign countries and governmental bodies, including the European Union and other relevant jurisdictions where we conduct business, have laws and regulations concerning the collection and use of PII and other data obtained from their residents or by businesses operating within their jurisdictions that are currently more restrictive than those in the United States. Additionally, within the United States, different states have enacted various regulations governing the treatment of PII. Any inability, or perceived inability, to adequately address privacy and data protection concerns, even if unfounded, or to comply with applicable laws, regulations, policies, industry standards, contractual obligations or other legal obligations, could result in additional cost and liability to Company officials or us, including substantial monetary fines, and could damage our reputation, inhibit sales and adversely affect our business.

Our extensive reliance on, and investments in, information technology systems, including reliance on third-party service providers, could have a materially adverse impact on our business.

We rely extensively on information technology systems and related personnel to collect, use, retain, manage, transmit, and protect transactions and data. For these information technology systems, applications, and processes to operate effectively, we or our service providers must maintain and update them. Delays in the maintenance, updates, upgrading, or patching of these systems, applications or processes, as well as the actions taken to maintain, update, upgrade and patch, could impair their effectiveness or expose us to security risks.

Some of these systems are managed or provided by third-party service providers, including certain cloud platform providers. Failure by these third-party service providers to meet their contractual, regulatory and other obligations to us, or our failure to

adequately monitor their performance, could result in our inability to achieve expected efficiencies and result in additional costs to correct errors made by such service providers. Depending on the function involved and despite the availability of contractual remedies against these providers, such errors can also lead to business disruption, systems performance degradation, processing inefficiencies or other systems disruptions, the loss of or damage to intellectual property or sensitive data through security breaches or otherwise, incorrect or adverse effects on financial reporting, litigation, claims, legal or regulatory proceedings, inquiries or investigations, fines or penalties, remediation costs, damage to our reputation or have a negative impact on employee morale, all of which can materially adversely affect our business.

In addition, we are currently making, and expect to continue to make, substantial investments in our information technology systems, infrastructure and personnel, in certain cases with the assistance of strategic partners and other third-party service providers. These investments involve replacing existing systems, some of which are older, legacy systems that are less flexible and efficient, with successor systems; outsourcing certain technology and business processes to third-party service providers; making changes to existing systems; maintaining or enhancing legacy systems that are not currently being replaced; designing or cost effectively acquiring new systems with new functionality; or testing the use and incorporation of AI, including generative AI. These efforts could result in significant potential risks, including failure of the systems to operate as designed, unexpected impacts on related systems or processes, potential loss or corruption of data, failures in security processes and internal controls, cost overruns, implementation delays or errors, disruption of operations, and the potential inability to meet business and reporting requirements. Any system implementation and transition difficulty may result in operational challenges, security failures, reputational harm, and increased costs that could adversely affect our business operations, our relationships with our customers, and results of operations.

Trends, Risks and Uncertainties Related to Regulation

Environmental and health and safety liabilities and expenditures could materially adversely affect our results of operations and financial condition.

The semiconductor industry continues to be subject to increasing environmental regulations, particularly those that control and restrict the use, transportation, emission, discharge, storage and disposal of certain chemicals, elements and materials used or produced in the semiconductor manufacturing process. In addition, our operations and those of our suppliers are further governed by regulations focused on conflict minerals and restrictions on other materials, as well as laws or regulations governing the operation of our facilities, sale and distribution of our products, and real property.

We also have operations subject to laws and regulations relating to workplace safety and worker health, which, among other requirements, regulate employee exposure to hazardous substances. We have indemnities from third parties for certain environmental and health and safety liabilities for periods prior to our operations at some of our current and past sites, and we have also purchased environmental insurance to cover certain claims related to historical contamination and future releases of hazardous substances. However, we cannot assure you that such indemnification arrangements and insurance will cover any or all of our material environmental costs. In addition, the nature of our operations exposes us to the continuing risk of environmental and health and safety liabilities including:

•changes in United States and international environmental or health and safety laws, regulations or policies, including, but not limited to, future laws or regulations imposed in response to climate change concerns and conflict minerals;

•the manner in which environmental or health and safety laws or regulations will be enforced, administered or interpreted;

•our ability to enforce and collect under indemnity agreements and insurance policies relating to environmental liabilities;

•the cost of compliance with future environmental or health and safety laws or regulations or the costs associated with any future environmental claims, including the cost of clean-up of currently unknown environmental conditions; or

•the cost of fines, penalties or other legal liability, should we fail to comply with environmental or health and safety laws or regulations.

We incur costs associated with complying with evolving environmental, health and safety laws and regulations and related disclosure obligations such as the Corporate Sustainability Reporting Directive. Failure to comply with these laws or regulations could subject us to significant costs and liabilities. To the extent that we face unforeseen environmental or health and safety compliance costs or remediation expenses or liabilities that are not covered by indemnities or insurance, we may bear the full effect of such costs, expenses and liabilities, which could materially adversely affect our results of operations and financial condition.

Our failure to comply with anti-corruption laws could result in penalties that could harm our reputation and have a material adverse effect on our business, financial condition and results of operations.

We are subject to the FCPA, which generally prohibits companies and their intermediaries from making improper payments to foreign officials for the purpose of obtaining or keeping business and/or other benefits, along with various other anti-corruption laws. Although we have implemented policies and procedures designed to ensure that we, our employees and other intermediaries comply with the FCPA and other anti-corruption laws to which we are subject, there is no assurance that such policies or procedures will work effectively all of the time or protect us against liability under the FCPA or other laws for actions taken by our employees and other intermediaries with respect to our business or any businesses that we may acquire. If

we are not in compliance with the FCPA and other laws governing the conduct of business with government entities (including local laws), we may be subject to criminal and civil penalties and other remedial measures, which could have a material adverse impact on our business, financial condition, results of operations and liquidity. Any investigation of any potential violations of the FCPA or other anti-corruption laws by the United States or foreign authorities could harm our reputation and have an adverse impact on our business, financial condition and results of operations.

Changes in tax legislation or exposure to additional tax liabilities could adversely affect our results of operations and financial condition.

We conduct operations worldwide through our foreign subsidiaries and are, therefore, subject to complex income tax and transfer pricing regulations in the United States and foreign jurisdictions. Changes to, or interpretations of, tax legislation or regulations could significantly increase our effective tax rate or affect our tax obligations and ultimately reduce our cash flow from operating activities. In addition, other factors or events, such as changes to our operating structure, strategy and investment decisions, could also increase our future effective tax rate or affect our tax obligations and ultimately reduce our cash flow from operating activities.

Changes in tax laws from international and domestic initiatives, such as the Organization for Economic Co-operation and Development's base erosion and profit shifting project and potential U.S. tax reforms, could adversely affect our future reported results of operations or the way we conduct our business. Most of our income is taxable in the United States with a significant portion qualifying for preferential treatment as foreign-derived intangible income (“FDII”). Beginning in 2026, the effective rate for FDII increases from 13% to 16%. Additionally, if U.S. rates increase and/or the FDII deduction is eliminated or reduced, our provision for income taxes, results of operations, and cash flows could be adversely (potentially materially) affected. Furthermore, if our customers move manufacturing operations to the United States, our FDII deduction may be reduced.

These types of initiatives and changes, if adopted or enacted, may increase tax uncertainty and may adversely affect our provision for income taxes, which could have a material impact on our results of operations and financial condition.

Furthermore, the impact of any new tax legislation may differ from our estimates, possibly materially, due to, among other things, changes in interpretations and assumptions we have made and future regulatory guidance.

Social and environmental responsibility regulations, policies and provisions, as well as customer and investor demands, may make our supply chain more complex and may adversely affect our relationships with customers and investors.

With the increasing focus on corporate social and environmental responsibility in the semiconductor industry, a number of our customers have adopted, or may adopt, procurement policies that include social and environmental responsibility provisions or requirements that their suppliers should comply with, or they may seek to include such provisions or requirements in their procurement terms and conditions. In addition, an increasing number of OEMs are seeking to source products that do not contain minerals sourced from areas where proceeds from the sale of such minerals are likely to be used to fund armed conflicts, such as in the Democratic Republic of Congo. This could adversely affect the sourcing, availability and pricing of minerals used in the manufacture of semiconductor devices, including our products. As a result, we may face difficulties in satisfying these customers’ demands, which may harm our sales and operating results.

Many investors also expect companies to disclose corporate social and environmental policies, practices and metrics under voluntary disclosure standards and frameworks. We periodically communicate our strategies, goals and targets related to our corporate social and environmental policies and programs. These strategies, goals and targets, and their underlying assumptions and projections, reflect our current plans and aspirations, but we may be unable to achieve them. It is also possible that our investors might not be satisfied with our policies, programs, goals, performance and related disclosures, or the speed of their adoption, implementation and measurable success, or that we have adopted such policies, programs and commitments at all.

In addition, unfavorable ratings or assessment of our corporate social and environmental policies and programs, including our compliance with certain voluntary disclosure standards and frameworks, may lead to negative investor sentiment toward us, which could have a negative impact on our stock price and our access to and cost of capital.

Furthermore, in light of our goal to achieve net zero emissions by 2040, future customer or investor expectations and regulatory requirements, we may take actions to pursue our goal of generating net-zero emissions or to alter our processes that may result in material expenditures that could impact our financial condition or results of operations and/or disrupt our existing operations.

Trends, Risks and Uncertainties Related to Our Indebtedness

Our debt could materially adversely affect our financial condition and results of operations.

As of December 31, 2024, we had $3,379.9 million of outstanding principal relating to our indebtedness. We may need to incur additional indebtedness in the future to repay or refinance other outstanding debt, to make acquisitions or for other purposes, and if we incur additional debt, the related risks that we now face could intensify. As of December 31, 2024, we had approximately $1.1 billion available for future borrowings under the Revolving Credit Facility. The degree to which we are leveraged could have important consequences to our potential and current investors, including impacting our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, and general corporate purposes.

To the extent that we continue to maintain or expand our significant indebtedness, our financial condition and results of operations may be materially adversely affected.

The inability to meet our obligations under our Credit Agreement could materially and adversely affect us by, among other things, limiting our ability to conduct our operations and reducing our flexibility to respond to changing business and economic conditions.

The obligations under the Credit Agreement are collateralized by a lien on substantially all of the assets of the guarantors under the Credit Agreement, including a pledge of the equity interests in certain of our domestic and first-tier foreign subsidiaries. As a result, if we are unable to satisfy our obligations under the Credit Agreement, the lenders could take possession of and foreclose on the pledged collateral securing the indebtedness, in which case we would be at risk of losing the related collateral, which would have a material adverse effect on our business and operations. In addition, the Credit Agreement requires mandatory prepayment if the outstanding amounts drawn thereunder exceed the total commitments, which may result in prepaying outstanding amounts under the Revolving Credit Facility rather than using funds for other business purposes. Our financing structure, and any inability to meet our obligations thereunder, could have a material adverse effect on our business and financial condition, including, among other things, our ability to obtain additional financing for working capital, capital expenditures, acquisitions, and other general corporate purposes and could reduce our flexibility to respond to changing business and economic conditions.

The agreements relating to our indebtedness, including the Credit Agreement and the 3.875% Notes, may restrict our ability to operate our business, and as a result may materially adversely affect our results of operations.

Our debt agreements, including the Credit Agreement and the 3.875% Notes, contain, and any future debt agreements may include, a number of restrictive covenants that impose significant operating and financial restrictions on us and our subsidiaries. Such restrictive covenants may significantly limit our ability to: incur additional debt; incur liens; make certain investments or acquisitions; redeem, or otherwise perform our obligations under the terms of, our 3.875% Notes; sell or otherwise dispose of assets; engage in mergers or consolidations or certain other "change of control" transactions; make distributions to our stockholders; engage in restructuring activities; engage in certain sale and leaseback transactions; and issue or repurchase stock or other securities.

Such agreements may also require us to satisfy other requirements, including maintaining certain financial ratios and condition tests. Our ability to meet these requirements can be affected by events beyond our control, and we may be unable to meet them. To the extent we fail to meet any such requirements and are in default under our debt obligations, our financial condition may be materially adversely affected.

We may not be able to generate sufficient cash flow to meet our debt service obligations, and any inability to repay our debt when required would have a material adverse effect on our business, financial condition and results of operations.

Our ability to generate sufficient cash flow from operating activities to make required payments on our debt obligations will depend on our future financial performance, which will be affected by a range of economic, competitive, and business factors, many of which are outside of our control. If we do not generate sufficient cash to satisfy our debt obligations as they come due, we may have to undertake alternative financing plans, such as refinancing or restructuring our debt, selling additional assets, reducing or delaying capital investments, or seeking to raise additional capital. We cannot assure you that any refinancing would be possible, that any assets could be sold, or, if sold, of the timing of the sales and the amount of proceeds realized from those sales, or that additional financing could be obtained on acceptable terms, if at all, or would be permitted under the terms of our various debt instruments then in effect.

Furthermore, we cannot assure you that, if we were required to repurchase any of our debt securities upon a change of control or other specified event, our assets or cash flow would be sufficient to fully repay borrowings under our outstanding debt instruments or that we would be able to refinance or restructure the payments on those debt securities. If we are unable to repay, refinance or restructure our indebtedness under our collateralized debt, the holders of such debt could proceed against the collateral securing that indebtedness, which could materially negatively impact our results of operations and financial condition. A default under our committed credit facilities, including our Credit Agreement, could also limit our ability to make further

borrowings under those facilities, which could materially adversely affect our business and results of operations. In addition, to the extent we are not able to borrow or refinance debt obligations, we may have to issue additional shares of our common stock, which would have a dilutive effect to the stockholders immediately prior to such issuance.

An event of default under any agreement relating to our outstanding indebtedness could cross default other indebtedness, which could have a material adverse effect on our business, financial condition and results of operations.

If there were an event of default under certain of our agreements relating to our outstanding indebtedness, the holders of the defaulted debt could cause all amounts outstanding with respect to that debt to be due and payable immediately, which default or acceleration of debt could cross default other indebtedness. Any such cross default would put immediate pressure on our liquidity and financial condition and would amplify the risks described above with regards to being unable to repay our indebtedness when due and payable. We cannot assure you that our assets or cash flow would be sufficient to fully repay borrowings under our outstanding debt instruments if accelerated upon an event of default and, as described above, any inability to repay our debt when due would have a material adverse effect on our business, financial condition and results of operations.

If our operating subsidiaries, which may have no independent obligation to repay our debt, are not able to make cash available to us for such repayment, our business, financial condition and results of operations may be adversely affected.

We conduct our operations through our subsidiaries. Repayment of our indebtedness is dependent on the generation of cash flow by our subsidiaries and their ability to make such cash available to us, by dividend, debt repayment or otherwise. Unless they are guarantors of our indebtedness, our subsidiaries have no obligation to pay amounts due on such indebtedness or to make funds available for that purpose. Our subsidiaries may not be able to, or may not be permitted to, make distributions to enable us to make payments in respect of our indebtedness. Each subsidiary is a distinct legal entity, and, under certain circumstances, legal, contractual, governmental, or regulatory restrictions may limit our ability to obtain cash from our subsidiaries. In the event that we do not receive distributions or payments from our subsidiaries, we may be unable to make required principal and interest payments on our indebtedness and, as described above, any inability to repay our debt when due would have a material adverse effect on our business, financial condition and results of operations.

If interest rates increase, our debt service obligations under our variable rate indebtedness could increase significantly, which would have a material adverse effect on our results of operations.

Borrowings under certain of our facilities from time to time, including under our Credit Agreement, are at variable rates of interest and as a result expose us to interest rate risk. Interest rates increased throughout 2022 and 2023. While interest rates have stabilized during 2024, if interest rates increase or remain at elevated levels, our debt service obligations on the variable rate indebtedness would increase even though the amount borrowed remained the same, and our net income and cash flows, including cash available for servicing our indebtedness, will correspondingly decrease. We may not maintain interest rate swaps with respect to all of our variable rate indebtedness, and any swaps we enter into may not fully mitigate our interest rate risk. To the extent the risk materializes and is not fully mitigated, the resulting increase in interest expense could have a material adverse effect on our results of operations. Further, significant changes in our credit rating, disruptions in the global financial markets, including bank failures, or incurrence of new or refinancing of existing indebtedness at higher interest rates could have a material and adverse effect on our access to and cost of capital for future financings, and financial condition.

The timing of the cash payments to service the 0% Notes, the 0.50% Notes and the 3.875% Notes is not entirely in our control and may require a significant amount of cash, and we may not have sufficient cash flow or the ability to raise the funds necessary to satisfy these obligations in a timely manner.

As of December 31, 2024, we had outstanding approximately $804.9 million aggregate principal amount of our 0% Notes, $1,500.0 million aggregate principal amount of our 0.50% Notes and $700.0 million aggregate principal amount of our 3.875% Notes (collectively, the "Outstanding Notes"). Holders of the Outstanding Notes have certain rights that would require us to make repurchases prior to the stated maturity for all or a portion of the amounts due in certain circumstances. For example, holders of the 3.875% Notes have the right to require us to repurchase all of their 3.875% Notes upon the occurrence of certain change of control triggering events accompanied by certain ratings events (as described in the indenture governing the 3.875% Notes) at a repurchase price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, accrued prior to, but not including, the repurchase date.

Servicing the Outstanding Notes may require a significant amount of cash, and we may not have sufficient cash flow or the ability to raise the funds necessary to satisfy our obligations under such notes. Our ability to make cash payments in connection with conversions of the 0% Notes or the 0.50% Notes, repurchase any of the Outstanding Notes in the case of an applicable repurchase-triggering event under the respective indentures or repay such notes at maturity will depend on market conditions and our future performance, which is subject to economic, financial, competitive, and other factors beyond our control.

In certain circumstances, a takeover of our Company and similar triggering events could also trigger an option of the holders of

the 0% Notes, the 0.50% Notes and the 3.875% Notes to require us to repurchase such notes. This may have the effect of delaying or preventing a takeover of our Company that would otherwise be beneficial to the holders of the 0% Notes, the 0.50% Notes, the 3.875% Notes and our common stock, which could materially decrease the value of such notes and of our common stock.

The terms of the Credit Agreement and the terms of the 3.875% Notes limit the amount of future indebtedness secured by liens that we may incur. If we incur significantly more debt, this could intensify the risks described above. Our decision to use our cash for other purposes, such as to make acquisitions or to repurchase our common stock, could also intensify these risks.

Note hedge and warrant transactions we have entered into may materially adversely affect the value of our common stock.

Concurrently with the issuances of the 0% Notes and the 0.50% Notes, respectively, we entered into note hedge transactions with certain financial institutions, which we refer to as the option counterparties. The convertible note hedges are expected to reduce the potential dilution upon any conversion of the respective series of notes and/or offset any cash payments we are required to make in excess of the principal amount of converted notes of such series, as the case may be. We also entered into warrant transactions with the option counterparties with respect to the 0% Notes and the 0.50% Notes. The warrant transactions could separately have a dilutive effect on our common stock to the extent that the market price per share of our common stock exceeds $74.34, with respect to the 0% Notes and $156.78 with respect to the 0.50% Notes.

In connection with establishing their initial hedge of the convertible note hedges and warrant transactions for the 0% Notes and the 0.50% Notes, the option counterparties or their respective affiliates have purchased shares of our common stock and/or entered into various derivative transactions with respect to our common stock. The option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives contracts with respect to our common stock and/or purchasing or selling our common stock or other securities of ours in secondary market transactions prior to the maturity of such notes. The potential effect, if any, of these transactions and activities on the market price of our common stock will depend in part on market conditions and cannot be ascertained at this time. Any of these activities could materially adversely affect the value of our common stock.

Counterparty risk with respect to the note hedge transactions, if realized, could have a material adverse impact on our results of operations.

The option counterparties are financial institutions or affiliates of financial institutions, and we are subject to the risk that these option counterparties may default under the note hedge transactions. We can provide no assurances as to the financial stability or viability of any of the option counterparties. Our exposure to the credit risk of the option counterparties is not secured by any collateral. If one or more of the option counterparties to one or more of our note hedge transactions becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at the time under those transactions.

To the extent the option counterparties do not honor their contractual commitments with us pursuant to the note hedge transactions, we could face a material increase in our exposure to potential dilution upon any conversion of the 0% Notes and/or the 0.50% Notes and/or cash payments we are required to make in excess of the principal amount of converted 0% Notes and/or the 0.50% Notes, as the case may be. Our exposure will depend on many factors but, generally, the increase in our exposure will be correlated to the increase in the market price of our common stock and in the volatility of the market price of our common stock. In addition, upon a default by one of the option counterparties, we may suffer adverse tax consequences with respect to our common stock. Any such adverse tax consequences or increased cash payments could have a material adverse effect on our results of operations.

Trends, Risks and Uncertainties Related to Our Common Stock

Provisions in our charter documents may delay or prevent the acquisition of us, which could materially adversely affect the value of our common stock.

Our certificate of incorporation and by-laws contain provisions that could make it harder for a third party to acquire us without the consent of our Board of Directors. These provisions:

•establish advance notice requirements for submitting nominations for election to the Board of Directors and for proposing matters that can be acted upon by stockholders at a meeting;

•authorize the issuance of "blank check" preferred stock, which is preferred stock that our Board of Directors can create and issue without prior stockholder approval and that could be issued with voting or other rights or preferences that could impede a takeover attempt; and

•require the approval by holders of at least 66 2/3% of our outstanding common stock to amend certain of these provisions in our certificate of incorporation or by-laws.

Although we believe these provisions make a higher third-party bid more likely by requiring potential acquirers to negotiate with our Board of Directors, these provisions apply even if an initial offer may be considered beneficial by some stockholders. Any delay or prevention of an acquisition of us that would have been beneficial to our stockholders could materially decrease the value of our common stock.

The amount and frequency of our share repurchases are affected by a number of factors and may fluctuate.

Although we have adopted a share repurchase program, we are not obligated to repurchase a specified number or dollar value of shares under our share repurchase program or at all. The amount, timing, and purchases under our share repurchase program, if any, are influenced by many factors and may fluctuate based on our operating results, cash flows, and priorities for the use of cash and because of changes in tax laws, and the market price of our common stock. In addition, we cannot guarantee that our share repurchase program will be fully consummated or that it will enhance long-term shareholder value.

General Risk Factors

We may be unable to successfully make or integrate strategic acquisitions, joint ventures or strategic investments, which could materially adversely affect our business, results of operations and financial condition.

We have made, and may continue to make, strategic acquisitions, investments and other alliances including the formation of joint ventures that involve significant risks and uncertainties. Successful acquisitions and alliances in our industry require, among other things, efficient integration and aligning of product offerings and manufacturing operations and coordination of sales and marketing and research and development efforts, often in markets or regions in which we have less experience. Risks related to successful integration of an acquisition include, but are not limited to: (1) the ability to integrate information technology and other systems; (2) issues not discovered in our due diligence; (3) customers responding by changing their existing business relationships with us or the acquired company; (4) diversion of management’s attention from our day to day operations; and (5) loss of key employees post-integration. In addition, we may incur unexpected costs or taxes resulting from the acquisition or integration of the newly acquired business. Missteps or delays in integrating our acquisitions, which could be caused by factors outside of our control, or our failure to realize the expected benefits of the acquisitions on the timeline we anticipate, could materially adversely affect our results of operations and financial condition.

Depending on the level of our ownership interest in and the extent to which we can exercise control over the acquired business, we may be required by U.S. generally accepted accounting principles ("GAAP") and SEC rules and regulations to consolidate newly acquired businesses into our consolidated financial statements. The acquired businesses may not have independent audited financial statements or statements prepared in accordance with GAAP, or the acquired businesses may have financial controls and systems that are not compatible with our financial controls and systems, any of which could materially impair our ability to properly integrate such businesses into our consolidated financial statements on a timely basis. Any revisions to, inaccuracies in or restatements of our consolidated financial statements due to accounting for our acquisitions could have a material adverse effect our financial condition and results of operations.

If our goodwill or amortizable intangible assets become impaired, we may be required to record a significant charge to earnings.

We acquire other companies and intangible assets and may not realize all the economic benefit from those acquisitions, which could cause an impairment of goodwill or intangible assets. We review our amortizable intangible assets for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. We test goodwill for impairment at least annually. Factors that may be a change in circumstances, indicating that the carrying value of our goodwill or amortizable intangible assets may not be recoverable, include a decline in our stock price and market capitalization, reduced future cash flow estimates, and slower growth rates in industry segments in which we participate. We have in the past recorded, and may in the future be required to record, a significant charge in our consolidated financial statements during the period in which any impairment of our goodwill or amortizable intangible assets is determined, negatively affecting our financial position and results of operations.

Downturns or volatility in general economic conditions, as well as general macroeconomic trends and impacts, could have an adverse impact on our business, results of operations, financial condition and cash flows.

Historically, worldwide semiconductor industry sales have tracked the impacts of adverse economic conditions, specifically financial crises, subsequent recoveries and persistent economic uncertainty. Recent global economic slowdowns could continue and potentially result in certain economies dipping into economic recessions, including in the United States.

We have in the past and could in the future experience period-to-period fluctuations in operating results due to general industry or economic conditions; the onset of an economic recession and volatile or uncertain economic conditions can adversely impact our sales and profitability and make it difficult for us and our competitors to accurately forecast and plan our future business activities. Furthermore, inflationary pressure and increases in interest rates have and may continue to increase our costs, which

could negatively impact revenue, earnings and demand for our products.

In addition to general economic conditions, impacts of other macroeconomic events, such as public health crises, geopolitical tensions or conflicts and risks, such as the ongoing conflict in the Middle East and military conflict between Russia and Ukraine, climate change and other severe weather and natural disasters, banking failures and uncertainties in global financial markets, could materially adversely impact our operations by causing disruptions in the geographies in which we and our suppliers, third party distributors and sub-contractors operate. If any of these events impact our supply chain, manufacturing and product shipments could be delayed, which could materially adversely affect our business, results of operations and financial condition. In addition, disruption of transportation and distribution systems could result in reduced operational efficiency and customer service interruption. Such events can negatively impact revenue and earnings and can significantly impact cash flow.

We have been and may be subject to or involved in litigation or threatened litigation, the outcome of which may be difficult to predict, and which may be costly to defend, divert management attention, require us to pay damages, or restrict the operation of our business.

From time to time, we have been and may be subject to disputes and litigation, with and without merit, that may be costly and which may divert the attention of our management and our resources in general. The results of complex legal proceedings are difficult to predict. Moreover, complaints filed against us may not specify the amount of damages that plaintiffs seek, and we therefore may be unable to estimate the possible range of damages that might be incurred should these lawsuits be resolved against us. Even if we are able to estimate losses related to these actions, the ultimate amount of loss may be materially higher than our estimates. Any resolution of litigation, or threatened litigation, could involve the payment of damages or expenses by us, which may be significant or involve an agreement with terms that restrict the operation of our business. Even if any future lawsuits are not resolved against us, the costs of defending such lawsuits may be significant. There can be no assurance that we are adequately insured to protect against all claims and potential liabilities. Allegations made in the course of legal proceedings may also harm our reputation, regardless of whether there is merit to such claims. We can provide no assurance that additional litigation will not be filed against us in the future. See Note 13: “Commitments and Contingencies – Legal Matters” in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for more information on our legal proceedings.

Regulatory and legislative developments related to climate change may materially adversely affect our business and financial condition.

Various jurisdictions have developed or are developing climate change-based laws or regulations that could cause us to incur additional direct costs for compliance, as well as indirect costs resulting from our customers, suppliers, or both incurring additional compliance costs that are passed on to us. These legal and regulatory requirements, as well as heightened investor expectations, on corporate environmental and social responsibility practices and disclosure are subject to change, can be unpredictable and may be difficult and expensive for us to comply with, given the complexity of our supply chain and our significant outsourced manufacturing. If we are unable to comply, or are unable to cause our suppliers to comply, with such policies or provisions or meet the requirements of our customers and investors, a customer may stop purchasing products from us or an investor may sell their shares, or parties may take legal action against us, which could harm our reputation, revenue and results of operations. Any future climate change regulations could also negatively impact our ability to compete with companies situated in areas not subject to such limitations. Given the political significance and uncertainty around the impact of climate change, we cannot predict how legislation and regulation will affect our financial condition, operating performance and ability to compete. Furthermore, increased awareness and any adverse publicity in the global marketplace about potential impacts on climate change by us or others in our industry could harm our reputation. Any of the foregoing could result in a material adverse effect on our business and financial condition.

Item 1C. Cybersecurity

Risk Management and Strategy

The secure processing, maintenance and transmission of sensitive data, including confidential and other proprietary information about our business and our employees, customers, suppliers and business partners, is important to our operations and business strategy. As a result, cybersecurity and data protection are key components of our long-term strategy.

We use various processes to inform our assessment, identification and management of risk from cybersecurity threats. Key areas of our cybersecurity risk management processes and strategy currently include:

•Cross-Functional Collaboration and Coordination. Our Enterprise Cybersecurity Services (“ECS”) team, led by our Chief Information Security Officer (“CISO”), has first line responsibility for our cybersecurity risk management processes. The ECS team works in partnership with other internal teams to coordinate efforts, priorities and oversight. These include:

◦our Cybersecurity Executive Council (the “Council”), which is composed of key leaders from stakeholder groups throughout the Company, including the CISO and certain members of senior management;

◦our Enterprise Risk Management (“ERM”) team, which is responsible for evaluating and assessing overall enterprise risk, including cybersecurity risk, and advising senior management and the Board regarding our overall risk profile and priorities as they evolve;

◦our Internal Audit Department (“IAD”), which monitors certain IT systems controls that are integrated into our larger Sarbanes-Oxley control environment; and

◦our Cyber Incident Response Team (“CIRT”), a cross-functional team of subject matter experts from across the Company and certain third-party support providers that we have on retainer.

•Ongoing Evaluation and Assessment of Systems and Processes. We update our information security management system from time to time as appropriate and we employ standards and frameworks as we deem necessary to assist us in monitoring compliance with regulatory, industry and evolving data privacy requirements. In addition to periodic in-depth evaluations of our systems and processes, we monitor our IT systems and processes on an ongoing basis with the goal of identifying and remediating real and potential threats as they arise. We adjust our systems, procedures and policies regularly as we deem necessary in response to identified threats and risks.

•Security Awareness Program to Train and Test Personnel. We sponsor a multi-faceted security awareness program that includes mandatory trainings for our personnel on data protection and malware detection, policy and process awareness, periodic phishing simulations and other kinds of preparedness testing.

•Cyber Incident Response Plan. We maintain a cross-functional cyber incident response plan with defined roles, responsibilities and reporting protocols. This plan, which we evaluate and test on a regular basis, focuses on responding to and recovering from any significant breach as well as mitigating any impact to our business. Generally, when a breach or suspected breach is identified, the ECS team would escalate the issue to the Council for initial analysis and guidance. In the event of a significant breach, the CIRT, overseen by the Council, would typically be tasked with preparing an initial response. The Council (in consultation with, among others, the CIRT) would be responsible for determining whether a particular incident (alone or in combination with other factors) triggers any reporting or notification responsibilities.

•Regular Evaluation of Initiatives, Results and Priorities. The ECS team, in consultation with the Council and other members of senior management, updates its strategy at least annually to account for changes in our business strategy, legal and regulatory developments across our geographic footprint, the results of our recent ECS initiatives, and further developments in the cybersecurity threat landscape. In addition, we periodically engage a third-party provider to conduct an external assessment of our security program. The results of this assessment, which are reported to the Audit Committee (and the Board, as appropriate), assist us in determining whether any further changes to our existing policies and practices are warranted.

We expect that our cybersecurity risk management processes and strategy will continue to evolve as the cybersecurity threat landscape evolves.

As indicated above, we engage third-party providers to assist us with our cybersecurity risk management and strategy. Some of these providers provide us with ongoing assistance (such as threat monitoring, mitigation strategies, updates on emerging trends and developments and policy guidance) while we engage others to provide targeted assistance (such as security and forensic expertise) as needed. Prior to exchanging any sensitive data or integrating with any key third-party provider, we assess their security fitness against our risk posture and request changes as we deem necessary.

As of December 31, 2024, we have not identified any risks from cybersecurity threats (including any previous cybersecurity incidents) that have materially affected the Company, our business strategy, our results of operations or our financial condition. For a discussion of risks from cybersecurity threats that could be reasonably likely to materially affect us, please see our Risk Factors discussion under the heading, “Trends, Risks and Uncertainties Related to Technology and Data Privacy” included

elsewhere in this Form 10-K.

Governance

Consistent with our overall risk management governance structure, management is responsible for the day-to-day management of cybersecurity risk while our Board and its Audit Committee play an active, ongoing oversight role.

Board Oversight. Our Board has delegated to its Audit Committee specific, first-line responsibility for overseeing major cybersecurity risk exposures in addition to our broader ERM program. Specifically, under its charter, the Audit Committee is responsible for overseeing our cybersecurity posture, risk assessment, strategy and mitigation and for making recommendations to address and resolve any breaches or issues related to the protection or privacy of our data. Management (including our Chief Information Officer (“CIO”) and our CISO) reports at least quarterly to the Audit Committee on information security and data privacy and protection. These presentations address a wide range of topics, including trends in cyber threats and the status of initiatives intended to bolster our security systems and the cyber readiness of our personnel. The Audit Committee chair reports to the full Board on these risk discussions as appropriate. At least annually, the Board meets with members of our ERM team to review and discuss our ERM program, including areas of material risk and how these risks, which may include cybersecurity risk, are being managed and reported to the Board and its committees.

Management’s Role. Our ECS team is composed of several support teams that address and respond to cyber risk, including cyber risks related to security architecture and engineering, identity and access management and security operations. The ECS team oversees compliance with our cybersecurity framework within the organization and facilitates cybersecurity risk management activities throughout the organization. The ECS team also assists with the review and approval of policies, completes benchmarking against applicable standards, maintains a cyber risk register and oversees the security awareness program.

Our ECS team is led by our CISO. Our CISO reports to our CIO who, in turn, reports to our Executive Vice President and Chief Financial Officer. Our CISO has over 20 years of experience in leading global security functions and strategies. Collectively, the other members of our ECS team have decades of relevant education and experience and maintain a wide range of industry certifications. We invest in regular, ongoing cybersecurity training for our ECS team.

As noted previously, our CISO is a member of the Council, which meets at least quarterly to provide operational direction to the ECS team considering the evolving risk landscape. The ECS team and the Council, through ongoing communication, monitor the prevention, detection, mitigation and remediation of cybersecurity threats and incidents. The CISO, in consultation with the Council and other members of senior management, reports such threats and incidents to the Audit Committee, as appropriate. These reports may be included in, or in addition to, his regular quarterly reports to the Audit Committee.

Item 2. Properties

Our corporate headquarters, as well as certain design center and research and development operations, are located in approximately 200,000 square feet of building space on property that we lease in Scottsdale, Arizona. We also own and lease properties around the world for use as sales offices, design centers, research and development labs, warehouses, logistic centers, trading offices and manufacturing support. The size and location of these properties, which are used by all of our reportable segments, change from time to time based on business requirements. We operate distribution centers, which are leased or contracted through a third-party, in locations throughout Asia, Europe and the Americas. See "Business — Resources" included elsewhere in this Form 10-K for information on properties used in our manufacturing operations. While these facilities are primarily used in manufacturing operations, they also include office, utility, laboratory, warehouse and unused space. Additionally, we own and lease research and development facilities located in Belgium, Canada, China, the Czech Republic, Germany, India, Ireland, Israel, Italy, Japan, the Philippines, Singapore, South Korea, Romania, the Slovak Republic, Slovenia, Switzerland, Taiwan, the United Kingdom and the United States. Our joint venture in Leshan, China also owns manufacturing, warehouse, laboratory, office and other unused space.

Certain of our properties are subject to encumbrances such as mortgages and liens. See Note 9: ''Long-Term Debt'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for further information. In addition, due to local law restrictions, the land upon which our facilities are located in certain foreign locations is subject to varying long-term leases. See "Business — Resources" and "Business — Government Regulation" included elsewhere in this Form 10-K for further details on our properties and environmental regulation.

Item 3. Legal Proceedings

The Company has elected to use a $1 million threshold for disclosing certain proceedings arising under federal, state or local environmental laws when a governmental authority is a party. The Company believes proceedings under this threshold are not material to its business and financial condition. See "Legal Matters" under Note 13: ''Commitments and Contingencies'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for a description of legal proceedings and related matters.

Item 4. Mine Safety Disclosure

Not applicable.

PART II

Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Our common stock is traded under the symbol "ON" on the Nasdaq Global Select Market. The stock price details can be obtained from the Nasdaq website at www.nasdaq.com. As of February 5, 2025, there were approximately 164 holders of record of our common stock and 421,421,127 shares of common stock outstanding. Holders of record are defined as those stockholders whose shares are registered in their names in our stock records and do not include beneficial owners of common stock whose shares are held in the names of brokers, dealers or clearing agencies.

Company Stock Performance

The following graph shows a comparison of the five-year cumulative total stockholder return for onsemi, the PHLX Semiconductor Sector Index ("SOX"), and the Standard and Poor's 500 ("S&P 500"). The comparison assumes $100 was invested on December 31, 2019 in shares of our common stock and in each of the indices shown and assumes that all of the dividends were reinvested. Note that past stock price performance is not necessarily indicative of future stock price performance. The performance graph in this Form 10-K shall be deemed furnished, and not filed, and shall not be deemed incorporated by reference into any filing under the Securities Act or the Exchange Act as a result of this furnishing, except to the extent that we specifically incorporate it by reference.

We have neither declared nor paid any cash dividends on our common stock since our initial public offering. Our future dividend policy with respect to our common stock will depend upon our earnings, capital requirements, financial condition, debt restrictions and other factors deemed relevant by our Board of Directors in its sole discretion.

Our outstanding debt facilities may limit the amount of dividends we are permitted to pay and share repurchases under the Share Repurchase Program (as defined below). We may pay dividends and buy back shares under the Share Repurchase Program in an unlimited amount so long as, after giving effect thereto, the consolidated total net leverage ratio (calculated in accordance with our Credit Agreement) does not exceed 2.75 to 1.00. Additionally, under a different provision, so long as no

default has occurred and is continuing or results therefrom, our Credit Agreement permits us to pay cash dividends to our common stockholders, buy back shares under the Share Repurchase Program, or a combination thereof, in an amount up to $350.0 million per year. See Note 9: ''Long-Term Debt'' in the notes to the audited consolidated financial statements included elsewhere in this Form 10-K for further discussion of our Credit Agreement.

Issuer Purchases of Equity Securities

The following table provides information regarding repurchases of our common stock during the quarter ended December 31, 2024:

Total	3,000,140	66.68		3,000,140

(1)The periods represent our fiscal month start and end dates for the fourth quarter of 2024.

(2)The price per share is based on the fair market value at the time of tender, repurchase or exercise of outstanding put options, respectively.

(3)Represents the authorized amount remaining under the Share Repurchase Program (as defined below) announced on February 6, 2023 to repurchase up to $3.0 billion of shares of our common stock through December 31, 2025 (exclusive of fees, commissions and other expenses).

Share Repurchase Program

In February 2023, the Board of Directors approved a share repurchase program (the “Share Repurchase Program”), which allows for the repurchase of our common stock from time to time through a variety of methods, including in privately negotiated transactions or open market transactions, such as pursuant to a trading plan in accordance with Rule 10b5-1 and Rule 10b-18 of the Exchange Act or a combination of methods. The Share Repurchase Program, which does not require us to purchase any minimum amount of our common stock, allows for repurchases up to $3.0 billion from February 8, 2023 through December 31, 2025 (exclusive of fees, commissions and other expenses). Any repurchases will be at the Company’s discretion and will be subject to market conditions, the price of our shares and other factors. The Share Repurchase Program may be modified, suspended or terminated by the Board of Directors at any time without prior notice.

The repurchases under the Share Repurchase Program amounted to an aggregate purchase price of approximately $650 million during the year ended December 31, 2024 (excluding fees, commissions and other expenses). There were approximately $564 million in repurchases of common stock for the year ended December 31, 2023 and approximately $260 million in repurchases of common stock under the previous share repurchase program during the year ended December 31, 2022 (in each case excluding fees, commissions and other expenses).

During January 2025, the Company acquired 1.6 million shares for $100.0 million under the Share Repurchase Program pursuant to a 10b5-1 trading arrangement.

See Note 10: ''Earnings Per Share and Equity'' of the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for further information on the Share Repurchase Program.

Item 6. [Reserved]

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

You should read the following discussion in conjunction with our audited historical consolidated financial statements, including the notes thereto, which are included elsewhere in this Form 10-K. Management's Discussion and Analysis of Financial Condition and Results of Operations contains statements that are forward-looking. These statements are based on current expectations and assumptions that are subject to risk, uncertainties, and other factors and speak only as of the filing date. Actual results could differ materially because of the factors discussed in "Risk Factors" and elsewhere in this Form 10-K.

Executive Overview

This executive overview presents summarized information regarding our business and operating trends only. For further details, please read "Management's Discussion and Analysis of Financial Condition and Results of Operations" in its entirety.

onsemi Results

Our revenue for the year ended December 31, 2024 was $7,082.3 million, representing a decrease of 14.2% from $8,253.0 million for the year ended December 31, 2023. During 2024, we reported net income attributable to onsemi of $1,572.8 million compared to $2,183.7 million in 2023. Our operating income totaled $1,767.7 million during 2024 compared to $2,538.7 million during 2023. Our gross margin decreased by approximately 170 basis points to 45.4% in 2024 from 47.1% in 2023. The decrease in our operating results was primarily due to decreased demand in our automotive and industrial end-markets resulting in lower sales volumes and the corresponding underutilization of our manufacturing facilities. See discussion under "Results of Operations" for the reasons for the fluctuations year-over-year.

Business and Macroeconomic Environment

The semiconductor industry has traditionally been highly cyclical, has often experienced significant downturns in connection with, or in anticipation of, declines in general economic conditions. During 2024, the semiconductor industry continued to experience a softening demand and uncertainty due to macroeconomic factors and the geopolitical environment. We are monitoring the economic environment and related forecasts for indicators that would suggest the global economic slowdown could continue for an extended period. Given the current conditions, we are actively managing and have taken corrective actions in our manufacturing capacity and spending to align with the forecasted demand. We intend to continue these actions during 2025; however, we believe the current volatility in general economic conditions is not expected to have a significant impact on our long-term strategic and growth initiatives.

We continue to evaluate cost-saving initiatives to be able to align our overall cost structure, capital investments and other expenditures with our expected revenue, spending and capacity levels to help offset softening demand, increased manufacturing and operating costs. We have taken, and continue to take actions, including but not limited to, exiting product lines that do not enhance gross margin or satisfy strategic objectives and aligning internal manufacturing capacity and resources to external demand.

See Note 7: ''Restructuring, Asset Impairments and Other Charges, net'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for information relating to our most recent cost-saving initiatives.

Revenue

Revenue was $7,082.3 million and $8,253.0 million for 2024 and 2023, respectively. The decrease from 2023 to 2024 of $1,170.7 million, or 14.2%, was attributable to lower sales volumes across all segments, which are further explained below. We had one customer, a distributor, whose revenue accounted for approximately 10% of our total revenue for the year ended December 31, 2024. There was no customer whose revenue exceeded 10% of total revenue for the year ended December 31, 2023.

Revenue from PSG

Revenue from PSG decreased by $532.2 million, or approximately 13.7%, during 2024 compared to 2023. Revenue from our Multi-Market Power Division, Industrial Power Division and Automotive Power Division decreased by $250.8 million, $162.2 million and $119.1 million, respectively, primarily driven by a decrease in demand in the automotive and industrial end-markets.

Revenue from AMG

Revenue from AMG decreased by $448.0 million, or approximately 14.7%, during 2024 compared to 2023. Revenue from our Power Management Division, Sensor Interface Division and Integrated Circuit Division decreased by $269.1 million, $101.5 million and $77.4 million, respectively, also due to the decrease in demand in the automotive and industrial end-markets.

Revenue from ISG

Revenue from ISG decreased by $190.5 million, or approximately 14.5%, during 2024 compared to 2023, which was driven by a decrease in revenue from our Industrial and Consumer Solutions Division and Automotive Sensing Division of $107.8 million and $82.7 million, respectively, primarily due to the decrease in demand in the automotive and industrial end-markets.

Revenue by Geographic Location

Revenue by geographic location, based on sales billed from the respective country or regions, was as follows (dollars in millions):


	2024		As a % of Revenue (1)		2023		As a % of Revenue (1)
Hong Kong	$	1,779.3	25.1	%	$	2,168.6	26.3	%

Total Revenue	$	7,082.3			$	8,253.0

(1)Certain of the amounts may not total due to rounding of individual amounts.

Gross Profit and Gross Margin

Gross profit was $3,216.1 million and $3,883.5 million for 2024 and 2023, respectively, representing a decrease of $667.4 million or approximately 17.2%. This was primarily due to the decline in sales volume in both our existing products and new products which negatively impacted gross profit by approximately $630 million and $122 million, respectively. This was partially offset by a reduction in the lower-margin manufacturing services revenue at our EFK location which favorably impacted gross profit by approximately $85 million.

Our gross margin decreased by 1.7 percentage points from 47.1% for the year ended December 31, 2023 to 45.4% for the year ended December 31, 2024, primarily due to the impact of the factors explained in the segment gross margin sections below.

PSG gross profit decreased by $437.4 million, primarily driven by the decline in sales volume in both existing products and new products which negatively impacted gross profit by approximately $316 million and $121 million, respectively. PSG gross margin decreased by 5.6 percentage points to 41.3% from 47.0%, primarily as a result of the decline in volume, underutilization of our manufacturing facilities, and the related impact of unfavorable product mix.

AMG gross profit decreased by $115.1 million, primarily driven by the decline in sales volume from existing products, which negatively impacted gross profit by approximately $200 million, partially offset by improved gross profit of approximately $85 million from the lower-margin manufacturing services at our EFK location. AMG gross margin increased by 3.6 percentage points to 50.1% from 46.5%, primarily due to the reduction in the lower-margin manufacturing services revenue at our EFK location.

ISG gross profit decreased by $114.9 million, primarily driven by the decline in sales volume from existing products. ISG gross margin decreased 2.0 percentage points to 46.7% from 48.7%, primarily driven by lower sales volumes and the related impact of the underutilization of our manufacturing facilities, along with unfavorable changes in product mix.

Operating Expenses

Research and Development

Research and development expenses were $612.7 million and $577.3 million, or approximately 9% and 7% of revenue for 2024 and 2023, respectively, representing an increase of $35.4 million, or approximately 6% year-over-year. The increase was primarily due to an increase in payroll-related expenses and production supplies, partially offset by a decrease in variable compensation.

Selling and Marketing

Selling and marketing expenses were $273.5 million and $279.1 million, or approximately 4% and 3% of revenue for 2024 and 2023, respectively, representing a decrease of $5.6 million, or approximately 2% year-over-year. The decrease was primarily related to a decrease in sales commissions and variable compensation.

General and Administrative

General and administrative expenses were $376.3 million and $362.4 million, or approximately 5% and 4% of revenue for 2024 and 2023, respectively, representing an increase of $13.9 million, or approximately 4% year-over-year. The increase was primarily due to increased consulting fees associated with information technology initiatives partially offset by a decrease in the bad debt provision with a strategic business partner which was recorded in the prior year.

Amortization of Acquisition-Related Intangible Assets

Amortization of acquisition-related intangible assets was $52.0 million and $51.1 million for 2024 and 2023, respectively, representing an increase of $0.9 million, or approximately 2%, year-over-year. Expenses were consistent between periods as there were no significant acquisitions or divestitures.

Restructuring, Asset Impairments and Other Charges, net

Restructuring, asset impairments and other charges, net was $133.9 million and $74.9 million for 2024 and 2023, respectively, representing an increase of $59.0 million. Amounts incurred during 2024 primarily represent severance and asset impairment charges associated with the 2024 business realignment efforts. Charges in 2023 related primarily to the business realignment efforts during 2023. For additional information, see Note 7: ''Restructuring, Asset Impairments and Other Charges, net'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K.

Other Income and Expenses

Interest Expense

Interest expense decreased by $12.5 million, or approximately 17%, to $62.3 million during 2024 compared to $74.8 million in 2023. The decrease was primarily due to the pay down of higher variable-rate debt and replacement by the 0.50% Notes in 2023. Our average gross amount of long-term debt balance (including current maturities) during 2024 and 2023 was $3,379.9 million and $3,304.1 million, respectively. Our weighted average interest rate on our gross amount of long-term debt (including current maturities) was 1.8% and 2.3% per annum in 2024 and 2023, respectively.

Interest income

Interest income increased by $18.3 million, or approximately 20%, to $111.4 million during 2024 compared to $93.1 million in 2023, primarily due to higher interest rates and increased balances in interest-bearing accounts.

See "Key Financing and Capital Events" below and Note 9: ''Long-Term Debt'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for a description of our indebtedness and our refinancing activities.

Loss on Debt Refinancing and Prepayment

There were no debt refinancing or prepayment transactions during 2024. We recorded a loss on debt refinancing and prepayment of $13.3 million during 2023, due to the write-off relating to the repayment of the Term Loan "B" Facility. See "Key Financing and Capital Events" below and Note 9: ''Long-Term Debt'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for a description of our indebtedness and our refinancing activities.

Other income (expense), net

Other income (expense), net was income of $20.6 million in 2024, compared to expense of $7.2 million in 2023. We received $9.5 million of dividend income in 2024 with no corresponding amounts in 2023. Actuarial gains on pension plans were $12.2 million compared to losses of $4.0 million during 2023 and fluctuations in foreign currencies resulting in increased transaction gains.

Income Tax Provision

We recorded an income tax provision of $262.8 million and $350.2 million in 2024 and 2023, respectively, representing effective tax rates of 14.3% and 13.8%.

For additional information, see Note 16: ''Income Taxes'' in the notes to the audited consolidated financial statements included elsewhere in this Form 10-K.

Liquidity and Capital Resources

Overview

Our principal sources of liquidity are cash on hand, cash generated from operations, available borrowings under our Revolving Credit Facility as well as new debt and/or equity issuances. In the near term, we expect to fund our cash requirements by utilizing any or a combination of these principal sources. Our cash and cash equivalents and short-term investments were approximately $2,691.3 million and $300.0 million, respectively, as of December 31, 2024 and our Revolving Credit Facility had approximately $1.1 billion available for future borrowings as of December 31, 2024.

We require cash to: (i) fund our operating expenses, working capital requirements, outlays for strategic acquisitions and investments; (ii) service our debt, including principal and interest; (iii) incur capital expenditures; and (iv) repurchase our common stock. During the ordinary course of business, we evaluate our cash requirements and, if necessary, adjust our expenditures to reflect the current market conditions and our projected sales and demand. Future capital expenditures may be impacted by events and transactions that are not currently forecasted.

We believe that the key factors that could adversely affect our internal and external sources of cash include:

•changes in demand for our products, competitive pricing pressures, supply chain constraints, effective management of our manufacturing capacity, our ability to achieve further reductions in operating expenses, our ability to make progress on the achievement of our business strategy and sustainability goals, the impact of our restructuring programs on our production and cost efficiency and our ability to make the research and development expenditures required to remain competitive in our business; and

•the debt and equity capital markets could impact our ability to obtain needed financing on acceptable terms or to respond to business opportunities and developments as they arise, including interest rate fluctuations, macroeconomic conditions, sudden reductions in the general availability of lending from banks or the related increase in cost to obtain bank financing and our ability to maintain compliance with covenants under our debt agreements in effect from time to time.

Sources and Uses of Cash

The following are the significant sources and uses of cash during 2024:

•Cash flows from operating activities of $1,906.4 million.

•Purchase of property, plant & equipment of $694.0 million.

•Repurchases of approximately 9.1 million shares of common stock for an aggregate purchase price of approximately $650 million under the Share Repurchase Program.

Operating Activities

Our long-term cash generation is dependent on our ability to generate cash from our operations. Our cash flows from operating activities were $1,906.4 million, $1,977.5 million and $2,633.1 million for the years ended December 31, 2024, 2023 and 2022, respectively. Our operating cash flows for the year ended December 31, 2024 decreased by $71.1 million, or 3.6%, compared to the year ended December 31, 2023 and was primarily attributable to a reduction in net income driven by lower end-market demand for our products partially offset by the timing of cash receipts and payments related to working capital balances.

Our ability to maintain positive operating cash flows is dependent on, among other factors, our success in achieving our revenue goals and meeting manufacturing and operating cost targets. Management of our assets and liabilities, including both working capital and long-term assets and liabilities, also influences our operating cash flows.

Investing Activities

Our cash flows used in investing activities were $1,009.8 million, $1,737.9 million and $705.4 million for the years ended December 31, 2024, 2023 and 2022, respectively. The decrease of $728.1 million for the year ended December 31, 2024 compared to the year ended December 31, 2023 was primarily attributable to a decrease in capital expenditures and payments for the acquisition of our EFK location during the year ended 2023, partially offset by the net impact of purchases and maturities of short-term investments. During the years ended December 31, 2024, 2023 and 2022, we paid $694.0 million, $1,539.1 million and $1,036.0 million, respectively, for capital expenditures. Our capital expenditures as a percent of revenue for the years ended December 31, 2024, 2023 and 2022 was approximately 10%, 19% and 12%, respectively. In 2025, based on current plans, we expect capital expenditures to be approximately 5% of revenue.

Financing Activities

Our cash flows used in financing activities were $683.8 million, $686.5 million and $370.0 million for the years ended December 31, 2024, 2023 and 2022, respectively. We used cash for share repurchases of $654.1 million for the year ended December 31, 2024 compared to $564.2 million in 2023. Additionally, during the year ended December 31, 2023, we had net cash outflows related to the establishment of our new Credit Agreement.

During January 2025, we acquired 1.6 million shares for $100.0 million under the Share Repurchase Program, subject to a 10b5-1 trading arrangement. We expect to continue to opportunistically repurchase under our Share Repurchase Program subject to market conditions, the price of our shares and other factors (including liquidity needs). However, the Share Repurchase Program may be modified, suspended or terminated by the Board of Directors at any time without prior notice.

See Part I, Item 1A "Risk Factors" included elsewhere in this Form 10-K for additional information related to liquidity matters.

Debt

As of December 31, 2024, we were in compliance with the indentures relating to our 0% Notes, 0.50% Notes and 3.875% Notes and with the financial covenants included in the Credit Agreement. The 0% Notes, 0.50% Notes and 3.875% Notes are senior to the existing and future subordinated indebtedness of onsemi and its guarantor subsidiaries, rank equally in right of payment to all of our existing and future senior debt and, as unsecured obligations, are subordinated to all of our existing and future secured debt to the extent of the assets securing such debt. Failure to comply with any of our covenants or any other terms of our Credit Agreement could result in higher interest rates in our borrowings or the acceleration of the maturities of our outstanding debt. In order to remain in compliance with the various financial covenants contained in our debt agreements and to fund working capital, our capital expenditures and business development efforts will depend on our ability to generate cash from operating activities, which is subject to, among other things, our future operating performance, as well as financial, competitive, legislative, regulatory and other conditions, some of which may be beyond our control.

As of December 31, 2024, there was outstanding $804.9 million aggregate principal amount of the 0% Notes, $1,500.0 million aggregate principal amount of the 0.50% Notes and $700.0 million aggregate principal amount of 3.875% Notes. The associated interest expense related to our indebtedness will continue to have a significant impact on our results of operations.

See Note 9: ''Long-Term Debt'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for additional information.

Key Financing and Capital Events

Overview

We continually evaluate our debt and capital structure and, when appropriate, we have completed various measures to secure liquidity, repurchase shares of our common stock, reduce interest costs, amend or replace existing key financing arrangements and, in some cases, extend a portion of our debt maturities to continue to provide us additional operating flexibility.

See Note 9: ''Long-Term Debt'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for additional information.

Critical Accounting Policies and Estimates

The accompanying discussion and analysis of our financial condition and results of operations is based upon our audited consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. We believe certain of our accounting policies are critical to understanding our financial position and results of operations. We utilize the following critical accounting policies in the preparation of our financial statements. In addition to our critical accounting policies below, see Note 2: ''Significant Accounting Policies'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K.

Use of Estimates. The preparation of financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements and the reported amount of revenue and expenses during the reporting period. We evaluate these estimates and judgments on an ongoing basis and base our estimates on experience, current and expected future conditions, third-party evaluations and various other assumptions that we believe are reasonable under the circumstances. Significant estimates have been used by management in conjunction with the following: (i) calculation of future payouts for customer incentives and amounts subject to allowances and returns; (ii) valuation and obsolescence relating to inventories; (iii) measurement of valuation allowances against deferred tax assets, and evaluations of uncertain tax positions; (iv) assumptions used in business combinations; and (v) testing for impairment of long-lived assets and goodwill. Actual results may differ from the estimates and assumptions used in the consolidated financial statements.

Revenue Recognition. We generate revenue from sales of our semiconductor products to direct customers and distributors. We also generate revenue, to a much lesser extent, from product development agreements and manufacturing services provided to customers. We apply a five-step approach in determining the amount and timing of revenue to be recognized: (i) identifying the contract with a customer; (ii) identifying the performance obligations in the contract; (iii) determining the transaction price; (iv) allocating the transaction price to the performance obligations in the contract; and (v) recognizing revenue when the

performance obligation is satisfied. We allocate the transaction price to each distinct product based on its relative stand-alone selling price. In determining the transaction price, we evaluate whether the price is subject to refund or adjustment to determine the net consideration to which we expect to be entitled.

We recognize revenue when we satisfy a performance obligation in an amount reflecting the consideration to which we expect to be entitled. Substantially all of our revenue is recognized at the time control of the products transfers to the customer. For sales agreements, we have identified the promise to transfer products, each of which is distinct, to be the performance obligation. For product development agreements, we have identified the completion of a service defined in the agreement to be the performance obligation. We recognize revenue from manufacturing services when we satisfy the performance obligation by transferring the promised goods or services to the customer. Depending on the terms of the applicable contractual agreement with the customer, revenue is recognized at the point in time when the customer obtains control of the promised goods or service, or over time when the created asset has no alternate use to us and there is an enforceable right to payment for the performance to date.

Sales to certain distributors, primarily those with ship and credit rights, can be subject to price adjustment on certain products. We develop an estimate of their expected claims under the ship and credit program based on the historical claims data submitted by product and customer and expected future claims, which requires the use of estimates and assumptions related to the amount of each claim as well as the historical period used to develop the estimate. Although payment terms vary, most distributor agreements require payment within 30 days.

Our direct customers do not have the right to return products other than pursuant to the provisions of our standard warranty. Sales to distributors, however, are typically made pursuant to agreements that provide return rights and stock rotation provisions permitting limited levels of product returns. Provisions for discounts and rebates to customers, estimated returns and allowances, ship and credit claims and other adjustments are provided for in the same period the related revenue is recognized, and are netted against revenue. For non-quality related returns, we recognize a related asset for the right to recover returned products with a corresponding reduction to cost of goods sold. Payment terms for direct customers generally require payment within 30 days but can extend up to 90 days. We record a reserve for cash discounts as a reduction to accounts receivable and a reduction to revenue, based on the experience with each customer.

Inventories. We carry our inventories at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or net realizable value and record provisions for potential excess and obsolete inventories based upon a regular analysis of inventory on hand compared to historical and projected end-user demand. The determination of projected end-user demand requires the use of estimates and assumptions related to projected unit sales for each product. These provisions can influence our results from operations. For example, when demand falls for a given part, all or a portion of the related inventory that is considered to be in excess of anticipated demand is reserved, impacting our cost of revenue and gross profit. The majority of product inventory that has been previously reserved is ultimately discarded. Although we do sell some products that have previously been written down, such sales have historically been consistently insignificant and the related impact on our margins has also been insignificant.

Income Taxes. Income taxes are accounted for using the asset and liability method. Under this method, deferred income tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for those deferred tax assets for which we cannot conclude that it is more likely than not that such deferred tax assets will be realized.

In determining the amount of the valuation allowance, estimated future taxable income, feasible tax planning strategies, future reversals of existing temporary differences and taxable income in prior carryback years, if a carryback is permitted, are considered. If we determine it is more likely than not that all or a portion of the remaining deferred tax assets will not be realized, the valuation allowance will be increased with a charge to income tax expense. Conversely, if we determine it is more likely than not to be able to utilize all or a portion of the deferred tax assets for which a valuation allowance has been provided, the related portion of the valuation allowance will be recorded as a reduction to income tax expense.

We recognize and measure benefits for uncertain tax positions using a two-step approach. The first step is to evaluate the tax position taken or expected to be taken in a tax return by determining if the weight of available evidence indicates that it is more likely than not that the tax positions will be sustained upon audit, including resolution of any related appeals or litigation processes. For tax positions that are more likely than not to be sustained upon audit, the second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon settlement. No tax benefit is recognized for tax

positions that are not more likely than not to be sustained. Our practice is to recognize interest and/or penalties related to income tax matters in income tax expense. Significant judgment is required to evaluate uncertain tax positions. Evaluations are based upon a number of factors, including changes in facts or circumstances, changes in tax law, correspondence with tax authorities during the course of tax audits and effective settlement of audit issues. Changes in the recognition or measurement of uncertain tax positions could result in material increases or decreases in income tax expense in the period in which the change is made, which could have a material impact on our effective tax rate.

Business Combinations. We use estimates and assumptions in allocating the purchase price of acquired business by utilizing established valuation techniques appropriate for the technology industry to record the acquired assets and liabilities at fair value. We utilize the income approach, cost approach or market approach, depending upon which approach is the most appropriate based on the nature and reliability of available data. If the income approach is used, the fair value determination is predicated upon the value of the future cash flows that an asset is expected to generate over its economic life and involves significant assumptions as to cash flows, associated expenses, long-term growth rates and discount rates. The cost approach takes into account the cost to replace (or reproduce) the asset and involves assumptions relating to the asset's value of physical, functional and/or economic obsolescence that has occurred with respect to the asset. The market approach is used to estimate value from an analysis of actual transactions or offerings for economically comparable assets available as of the valuation date. Determining the fair value of acquired technology assets is judgmental in nature and requires the use of significant estimates and assumptions, including the discount rate, revenue growth rates, projected gross margins, and estimated research and development expenses.

Impairment of Goodwill and Long-Lived Assets. We evaluate our goodwill for potential impairment annually during the fourth quarter and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. Our impairment evaluation consists of a qualitative assessment, and if deemed necessary, a quantitative test is performed which compares the fair value of a reporting unit with its carrying amount, including goodwill.

Determining the fair value of our reporting units is subjective in nature and involves the use of significant estimates and assumptions, including projected net cash flows, discount and long-term growth rates. We determine the fair value of our reporting units based on an income approach, whereby the fair value of the reporting unit is derived from the present value of estimated future cash flows. The assumptions about estimated cash flows include factors such as future revenue, gross profit, operating expenses, and industry trends. We consider historical rates and current market conditions when determining the discount and long-term growth rates to use in its analysis. We consider other valuation methods, such as the cost approach or market approach, if it is determined that these methods provide a more representative approximation of fair value.

We evaluate the recoverability of the carrying amount of our property, plant and equipment and intangible assets, whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be fully recoverable. Impairment is first assessed when the undiscounted expected cash flows derived for an asset group are less than its carrying amount. Impairment losses, if applicable, are measured as the amount by which the carrying value of an asset group exceeds its fair value and are recognized in operating results. We continually apply our best judgment when applying these impairment rules to determine the timing of the impairment test, the undiscounted cash flows used to assess impairments and the fair value of an impaired asset group. The dynamic economic environment in which we operate and the resulting assumptions used to estimate future cash flows impact the outcome of our impairment tests. As we continue to implement our business strategy to rationalize products and manufacturing locations to transition to a lighter internal fabrication model, there could be divestiture transactions that result in a portion of goodwill or other assets being de-recognized and result in accounting charges.

Contingencies. We are involved in a variety of legal matters that arise in the normal course of business. Based on the available information, we evaluate the relevant range and likelihood of potential outcomes and we record the appropriate liability when the amount is deemed probable and reasonably estimable.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to financial market risks, including changes in interest rates and foreign currency exchange rates. To mitigate these risks, we utilize derivative financial instruments. We do not use derivative financial instruments for speculative or trading purposes.

As of December 31, 2024, our gross long-term debt totaled $3,379.9 million. We have no interest rate exposure to rate changes on our fixed rate debt, which totaled $3,004.9 million. We do have interest rate exposure with respect to our Revolving Credit Facility, which had a $375.0 million balance as of December 31, 2024. We estimate a 50-basis point increase in interest rates would impact our expected annual interest expense for the next 12 months by approximately $1.9 million. However, this impact may be partially offset by the additional interest earned on our cash and cash equivalents.

To ensure the adequacy and effectiveness of our foreign exchange hedge positions, we continually monitor our foreign exchange forward positions. However, given the inherent limitations of forecasting and the anticipatory nature of exposures intended to be hedged, we cannot provide any assurances that such programs will offset more than a portion of the adverse financial impact resulting from unfavorable movements in foreign exchange rates.

We are subject to risks associated with transactions that are denominated in currencies other than our functional currencies, as well as the effects of translating amounts denominated in a foreign currency to the U.S. dollar as a normal part of the reporting process. Some of our Japanese operations utilize Japanese Yen as the functional currency, which results in a translation adjustment that is included as a component of accumulated other comprehensive income.

We enter into forward foreign currency contracts that economically hedge the gains and losses generated by the re-measurement of certain recorded assets and liabilities in a non-functional currency. Changes in the fair value of these undesignated hedges are recognized in other income and expense immediately as an offset to the changes in the fair value of the assets or liabilities being hedged. The notional amount of foreign exchange contracts at December 31, 2024 and 2023 was $256.8 million and $262.2 million, respectively.

Substantially all of our revenue is transacted in U.S. dollars. However, a significant amount of our operating expenditures and capital purchases are transacted in local currencies, including Chinese Renminbi, Czech koruna, euros, Japanese yen, Korean won, Malaysian ringgit, Philippine peso and Vietnamese dong. Due to the materiality of our transactions in these local currencies, our results are impacted by changes in currency exchange rates measured against the U.S. dollar. For example, we determined that based on a hypothetical weighted-average change of 10% in currency exchange rates, our operating income would have impacted our income before taxes by approximately $110.6 million for the year ended December 31, 2024, assuming no offsetting hedge position or correlated activities.

See Note 15: ''Financial Instruments'' in the notes to the audited consolidated financial statements included elsewhere in this Form 10-K for further information with respect to our hedging activity.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures.

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act). Based upon that evaluation, our Chief Executive Officer and Chief

Financial Officer concluded that, as of the end of the period covered in this Form 10-K, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act are recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including the principal executive officer and principal financial officer, to allow timely decisions regarding disclosure.

Changes in Internal Control Over Financial Reporting.

We also carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that occurred during the fiscal quarter ended December 31, 2024.

There have been no changes to our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) that occurred during the fiscal quarter ended December 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management's Report on Internal Control Over Financial Reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)). Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2024. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework 2013. Based on this assessment, management has concluded that our internal control over financial reporting was effective as of December 31, 2024.

The effectiveness of our internal control over financial reporting as of December 31, 2024 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears in "Exhibits and Financial Statement Schedules" of this Form 10-K.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of ON Semiconductor Corporation

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of ON Semiconductor Corporation and its subsidiaries (the "Company") as of December 31, 2024 and 2023, and the related consolidated statements of operations and comprehensive income, of stockholders’ equity and of cash flows for each of the three years in the period ended December 31, 2024, including the related notes and financial statement schedule listed in the index appearing under Item 15(a)(2) (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

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

Definition and Limitations of Internal Control over Financial Reporting

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

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

Critical Audit Matters

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

Valuation of Inventories

As described in Notes 2 and 8 to the consolidated financial statements, the Company’s inventory balance of $2,242.0 million as of December 31, 2024, is stated at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or net realizable value. Management writes down excess and obsolete inventories based upon a regular analysis of inventory on hand compared to historical and projected end-user demand.

The principal considerations for our determination that performing procedures relating to the valuation of inventories is a critical audit matter are the significant judgment by management in developing the write down for excess and obsolete inventories. This in turn led to a high degree of auditor judgment, subjectivity and effort in performing procedures to evaluate the reasonableness of management’s analysis, including the inputs utilized and the significant assumptions related to projected end-user demand employed within the analysis.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the valuation of inventories. These procedures also included, among others (i) testing management’s process for developing the write down for excess and obsolete inventories, (ii) evaluating the appropriateness of the analysis, and (iii) evaluating the reasonableness of the significant assumptions related to projected end-user demand used by management in developing the write down for excess and obsolete inventories. Evaluating the reasonableness of the assumptions related to projected end user demand involved considering the performance of product sales and whether they were consistent with evidence obtained in other areas of the audit.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1: Background and Basis of Presentation

ON Semiconductor Corporation, with its wholly and majority-owned subsidiaries ("onsemi" or the "Company"), operates under the onsemiTM brand, and prepares its consolidated financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP"). Certain reclassifications within the statements of cash flows have been made to prior period amounts to conform to current period presentation. The Company is organized into three operating and reportable segments: the Power Solutions Group ("PSG"), the Analog and Mixed-Signal Group ("AMG") and the Intelligent Sensing Group ("ISG"). During the first quarter of 2024, onsemi reorganized the existing divisions within certain of its operating and reportable segments and renamed the Advanced Solutions Group ("ASG") reportable segment to AMG. See Note 3: ''Segments and Revenue'' for additional information regarding the segment reorganization. Unless otherwise noted, all dollar amounts are in millions, except per share amounts.

Note 2: Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the assets, liabilities, revenue and expenses of all wholly-owned and majority-owned subsidiaries over which the Company exercises control and, when applicable, entities in which the Company has a controlling financial interest or is the primary beneficiary. Investments in affiliates where the Company does not exert a controlling financial interest are not consolidated. All intercompany balances and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements and the reported amount of revenue and expenses during the reporting period. Management evaluates these estimates and judgments on an ongoing basis and bases its estimates on experience, current and expected future conditions, third-party evaluations and various other assumptions that management believes are reasonable under the circumstances. Significant estimates have been used by management in conjunction with the following: (i) calculation of future payouts for customer incentives and amounts subject to allowances and returns; (ii) valuation and obsolescence relating to inventories; (iii) measurement of valuation allowances against deferred tax assets, and evaluations of uncertain tax positions; (iv) assumptions used in business combinations; and (v) testing for impairment of long-lived assets and goodwill. Actual results may differ from the estimates and assumptions used in the consolidated financial statements.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand, demand deposits and highly liquid investments with original maturities at the time of purchase of three months or less. The Company maintains amounts on deposit at various financial institutions, which may at times exceed federally insured limits. However, management periodically evaluates the credit-worthiness of those institutions and has not experienced any losses on such deposits.

Short-Term Investments

Short-term investments are comprised of time deposits with original maturities of greater than three months at the time of purchase. Interest on these investments are included within Interest income.

Inventories

Inventories are stated at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or net realizable value. General market conditions, as well as the Company's design activities, can cause certain of its products to become obsolete. The Company writes down excess and obsolete inventories based upon a regular analysis of inventory on hand compared to historical and projected end-user demand. The determination of projected end-user demand requires the use of estimates and assumptions related to projected unit sales for each product. These write downs can influence results from operations. For example, when demand for a given part falls, all or a portion of the related inventory that is considered to be in excess of anticipated demand is written down, impacting cost of revenue and gross profit. The majority of product inventory that has been previously written down is ultimately discarded. Although the Company does sell some products that have

Table of Contents

ON SEMICONDUCTOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

previously been written down, such sales have historically been consistently insignificant and the related impact on the Company's gross profit has also been insignificant.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost and are depreciated over estimated useful lives of 30 years for buildings and 3-20 years for computers, machinery and equipment using straight-line methods. Expenditures for maintenance and repairs are charged to operations in the period in which the expenses are incurred. When assets are retired or otherwise disposed of, the related costs and accumulated depreciation are removed from the balance sheet and any resulting gain or loss is reflected in operations in the period realized.

The Company evaluates the recoverability of the carrying amount of its property, plant and equipment whenever events or changes in circumstances indicate that the carrying value of an asset group may not be fully recoverable. A potential impairment charge is evaluated when the undiscounted expected cash flows derived from an asset group are less than its carrying amount. Impairment losses, if applicable, are measured as the amount by which the carrying value of an asset group exceeds its fair value. Judgment is used when applying these impairment rules to determine the timing of the impairment test, the undiscounted cash flows used to assess impairments and the fair value of the asset group.

Business Combination Purchase Price Allocation

The allocation of the purchase price of business combinations is based on management estimates and assumptions, which utilize established valuation techniques appropriate for the technology industry. These techniques include the income approach, cost approach or market approach, depending upon which approach is the most appropriate based on the nature and reliability of available data. Management records the acquired assets and liabilities at fair value. If the income approach is used, the fair value determination is predicated upon the value of the future cash flows that an asset is expected to generate over its economic life. The cost approach takes into account the cost to replace (or reproduce) the asset and the effects on the asset's value of physical, functional and/or economic obsolescence that has occurred with respect to the asset. The market approach is used to estimate value from an analysis of actual market transactions or offerings for economically comparable assets available as of the valuation date. Determining the fair value of acquired technology assets is judgmental in nature and requires the use of significant estimates and assumptions, including the discount rate, revenue growth rates, projected gross margins, and estimated research and development and other operating expenses.

Goodwill

Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired in a business combination. The Company evaluates its goodwill for impairment annually during the fourth quarter and whenever events or changes in circumstances indicate the carrying value of a reporting unit may not be recoverable. The Company’s divisions are one level below the operating segments, constituting individual businesses, at which level the Company’s segment management conducts regular reviews of the operating results. The Company's divisions, either individually or in a combination, constitute reporting units for purposes of allocating and testing goodwill.

The Company's impairment evaluation consists of a qualitative assessment. If this assessment indicates that it is more likely than not the estimated fair value of a reporting unit exceeds its carrying value, goodwill is not considered impaired. Otherwise, a quantitative impairment test is performed by comparing the fair value of a reporting unit to its carrying value, including goodwill. The Company can bypass the qualitative assessment for any period and proceed directly to the quantitative impairment test. If the carrying value of the net assets associated with the reporting unit exceeds the fair value of the reporting unit, goodwill is considered impaired and will be determined as the amount by which the reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill.

Determining the fair value of the Company's reporting units is subjective in nature and involves the use of significant estimates and assumptions, including projected net cash flows, discount rates and long-term growth rates. The Company determines the fair value of its reporting units based on an income approach derived from the present value of estimated future cash flows. The assumptions about estimated cash flows include factors such as future revenue, gross profit, operating expenses and industry trends. The Company considers historical rates and current market conditions when determining the discount and long-term growth rates to use in its analysis. The Company considers other valuation methods, such as the cost approach or market approach, if it is determined that these methods provide a more representative approximation of fair value.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Intangible Assets

The Company's acquisitions have resulted in intangible assets consisting of values assigned to customer relationships, patents, developed technology, licenses, and trademarks, which are considered long-lived assets and are stated at cost less accumulated amortization. These intangible assets are amortized over their estimated useful lives and are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of an asset group containing these assets may not be recoverable.

Leases

The Company determines if an arrangement is a lease at its inception. Operating and financing lease arrangements are comprised primarily of real estate and equipment agreements. ROU assets are included in other assets and the corresponding lease liabilities, depending on their maturity, are included in accrued expenses and other current liabilities or other long-term liabilities.

ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. The lease term includes options to extend the lease when it is reasonably certain that the option will be exercised. Leases with a term of 12 months or less are not recorded on the Consolidated Balance Sheet.

The Company uses its estimated incremental borrowing rate in determining the present value of lease payments considering the term of the lease, which is derived from information available at the lease commencement date, giving consideration to publicly available data for instruments with similar characteristics. The Company accounts for the lease and non-lease components as a single lease component.

Debt Issuance Costs

Debt issuance costs for the Company's revolving credit facilities are capitalized and amortized over the term of the facility on a straight-line basis. Amortization is included in interest expense while the unamortized balance is included in other assets.

Debt issuance costs for the Company's convertible notes, senior notes and term debt are recorded as a direct deduction from the carrying amounts of such debt, consistent with debt discounts, and are amortized over their term using the effective interest method. Amortization is included in interest expense.

Government Incentives

The Company receives government incentives for various reasons including capital expenditures, operating expenses, or to develop specific technologies, which may require the Company to meet or maintain certain metrics, and may be subject to reduction, termination, or recapture if such conditions are not met or maintained. Incentives related to the acquisition or construction of property, plant and equipment are recognized as a reduction in the cost-basis of the underlying assets with a reduction to depreciation expense based on the useful lives of the related assets. Incentives related to specific operating activities are offset against the related expense in the period the expense is incurred. Government incentives received prior to being earned are recognized in current or non-current liabilities or restricted cash, whereas incentives earned prior to being received are recognized in current or non-current receivables. Cash incentives related to operating expenses along with incentives that can offset taxes payable are included in operating activities, while cash received related to the acquisition of property, plant, and equipment are included in investing activities in the Consolidated Statements of Cash Flows.

Contingencies

The Company is involved in a variety of legal and IP matters and environmental, financing and indemnification contingencies that arise in the ordinary course of business. Based on the information available, management evaluates the relevant range and likelihood of potential outcomes and records the appropriate liability when the amount is deemed probable and reasonably estimable.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Treasury Stock

Treasury stock is recorded at cost, inclusive of fees, commissions and other expenses, when outstanding common shares are repurchased, bond hedges issued in connection with the convertible notes are settled and when outstanding shares are withheld to satisfy tax withholding obligations in connection with certain shares pursuant to RSUs under the Company's share-based compensation plans. Re-issuance of shares held in treasury stock is accounted for on a first-in, first-out basis.

Revenue Recognition

The Company generates revenue from sales of its semiconductor products to direct customers and distributors. The Company also generates revenue, to a much lesser extent, from product development agreements and manufacturing services provided to customers. The Company applies a five-step approach in determining the amount and timing of revenue to be recognized: (i) identifying the contract with a customer; (ii) identifying the performance obligations in the contract; (iii) determining the transaction price; (iv) allocating the transaction price to the performance obligations in the contract; and (v) recognizing revenue when the performance obligation is satisfied. The Company allocates the transaction price to each distinct product based on its relative stand-alone selling price. In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled.

Revenue is recognized when the Company satisfies a performance obligation in an amount reflecting the consideration to which it expects to be entitled. For sales agreements, the Company has identified the promise to transfer products, each of which is distinct, as the performance obligation. The Company recognizes revenue from sales agreements upon transferring control of a product to the customer, which typically occurs when products are shipped or delivered, depending on the delivery terms, or when products that are consigned at customer locations are consumed. Revenue is also recognized over time for products with no alternative use and an enforceable right to payment as they are manufactured, which represents a contract asset. The Company can receive cash payments from customers in advance of the performance obligation being satisfied, which represents a contract liability. Contract liabilities are recognized as revenue when the performance obligations are satisfied.

Frequently, the Company receives orders with multiple delivery dates that may extend across reporting periods. Each delivery constitutes an individual performance obligation, which consists of transferring control of the products to the customers based on their stand-alone selling price. The Company invoices the customer for each delivery upon shipment and recognizes revenue in accordance with delivery terms. As scheduled delivery dates are within one year, revenue allocated to future shipments of partially completed contracts is not disclosed.

For product development agreements, the Company has identified the completion of a service defined in the agreement as the performance obligation. The Company recognizes revenue from product development agreements over time based on the cost-to-cost method. The Company recognizes revenue from manufacturing services when it satisfies the performance obligation by transferring the promised goods or services to the customer. Depending on the terms of the applicable contractual agreement with the customer, revenue is recognized at the point in time when the customer obtains control of the promised goods or service, or over time when the created asset has no alternate use to the Company and there is an enforceable right to payment for the performance to date.

Sales agreements with customers are renewable periodically and contain terms and conditions with respect to payment, delivery, warranty and supply. In the absence of a sales agreement, the Company’s standard terms and conditions apply. Payment terms for direct customers generally require payment within 30 days but can extend up to 90 days. The Company considers the customer purchase orders, governed by sales agreements or the Company’s standard terms and conditions, to be the contract with the customer. The Company evaluates certain factors including the customer’s ability to pay (or credit risk). The Company’s direct customers do not have the right to return products, other than pursuant to the provisions of the Company’s standard warranty. Sales to distributors, however, are typically made pursuant to agreements that provide return rights and stock rotation provisions permitting limited levels of product returns. Sales to certain distributors, primarily those with ship and credit rights, can also be subject to price adjustment on certain products. Although payment terms vary, most distributor agreements require payment within 30 days. In addition, the Company offers cash discounts to certain customers for payments received within an agreed upon time, generally ten days after shipment, which is recorded as a reduction to revenue.

Sales returns and allowances, which include ship and credit reserves for distributors, are estimated based on historical claims data and expected future claims. Provisions for discounts and rebates to customers, estimated returns and allowances, ship and credit claims and other adjustments are provided for in the same period the related revenue is recognized, and are netted against revenue. The Company records freight and handling costs associated with outbound freight after control over a product has

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

transferred to a customer as a fulfillment cost and includes it in cost of revenue. Taxes assessed by government authorities on revenue-producing transactions, including value-added and excise taxes, are presented on a net basis (excluded from revenue). The Company generally warrants that products sold to its customers will, at the time of shipment, be free from defects in workmanship and materials and conform to specifications. The Company’s standard warranty extends for a period of two years from the date of delivery, except in the case of image sensor products, which are warrantied for one year from the date of delivery. At the time revenue is recognized, the Company establishes an accrual for estimated warranty expenses associated with its sales and records them as a component of the cost of revenue.

Research and Development Costs

Research and development costs are expensed as incurred.

Income Taxes

Income taxes are accounted for using the asset and liability method. Under this method, deferred income tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for those deferred tax assets for which management cannot conclude that it is more likely than not that such deferred tax assets will be realized.

In determining the amount of the valuation allowance, estimated future taxable income, feasible tax planning strategies, future reversals of existing temporary differences and taxable income in prior carryback years, if a carryback is permitted, are considered. If the Company determines it is more likely than not that all or a portion of the remaining deferred tax assets will not be realized, the valuation allowance will be increased with a charge to income tax expense. Conversely, if the Company determines it is more likely than not to be able to utilize all or a portion of the deferred tax assets for which a valuation allowance has been provided, the related portion of the valuation allowance will be recorded as a reduction to income tax expense.

The Company recognizes and measures benefits for uncertain tax positions using a two-step approach. The first step is to evaluate the tax position taken or expected to be taken in a tax return by determining if the weight of available evidence indicates that is it more likely than not that the tax positions will be sustained upon audit, including resolution of any related appeals or litigation processes. For tax positions that are more likely than not to be sustained upon audit, the second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon settlement. No tax benefit is recognized for tax positions that are not more likely than not to be sustained. The Company's practice is to recognize interest and/or penalties related to income tax matters in income tax expense. Significant judgment is required to evaluate uncertain tax positions. Evaluations are based upon a number of factors, including changes in facts or circumstances, changes in tax law, correspondence with tax authorities during the course of tax audits and effective settlement of audit issues. Changes in the recognition or measurement of uncertain tax positions could result in significant increases or decreases in income tax expense in the period in which the change is made, which could have a significant impact on the Company's effective tax rate.

Foreign Currencies

Most of the Company's foreign subsidiaries conduct business primarily in U.S. dollars and, as a result, utilize the U.S. dollar as their functional currency. For the remeasurement of financial statements of these subsidiaries, assets and liabilities in foreign currencies that are receivable or payable in cash are remeasured at current exchange rates, while inventories and other non-monetary assets in foreign currencies are remeasured at historical rates. Gains and losses resulting from the remeasurement of such financial statements are included in the operating results, as are gains and losses incurred on foreign currency transactions.

Some of the Company's Japanese subsidiaries utilize Japanese Yen as their functional currency. The assets and liabilities of these subsidiaries are translated at current exchange rates, while revenue and expenses are translated at the average rates in effect for the period. The related translation gains and losses are included in other comprehensive income or loss within the Consolidated Statements of Operations and Comprehensive Income.

Table of Contents

ON SEMICONDUCTOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Defined Benefit Pension Plans

The Company maintains defined benefit pension plans covering certain of its foreign employees. Net periodic pension costs and pension obligations are determined based on actuarial assumptions, including discount rates for plan obligations, assumed rates of return on pension plan assets and assumed rates of compensation increases for employees participating in plans. These assumptions are based upon management's judgment and consultation with actuaries, considering all known trends and uncertainties. The service cost component of the net periodic pension cost is allocated between the cost of revenue, research and development, selling and marketing and general and administrative line items, while the other components are included in other expense in the Consolidated Statements of Operations and Comprehensive Income.

Fair Value Measurement

The Company measures certain of its financial and non-financial assets at fair value by using the fair value hierarchy that prioritizes certain inputs into individual fair value measurement approaches. The fair value hierarchy is based on three levels of inputs, of which the first two are considered observable and the third, unobservable. The Company has elected not to carry any of its debt instruments at fair value.

Note 3: Segments and Revenue

Segments

As of December 31, 2024, the Company was organized into three operating and reportable segments consisting of PSG, AMG and ISG. These segments represent management's view of the business for which separate financial information is available and evaluated regularly by the Chief Operating Decision Maker ("CODM"), which is the Company’s Chief Executive Officer. The CODM uses segment gross profit for evaluating product pricing, factory utilization, allocation of capital and the assessment of segment profitability. The operating costs of manufacturing facilities which service all business units are reflected in each segment's cost of revenue on the basis of product costs. Because operating segments are generally defined by the products they design and sell, they do not sell to each other. The Company does not allocate income taxes or interest expense to its operating segments as the operating segments are principally evaluated on gross profit. Additionally, restructuring, asset impairments and other charges, net and certain other operating expenses, which include corporate research and development costs and miscellaneous nonrecurring expenses, are not allocated to segments.

PSG formerly included the divisions of Advanced Power Division and Integrated Circuits, Protection and Signal Division ("IPS"). During the first quarter of 2024, management reorganized these divisions to the divisions of Automotive Power Division, Industrial Power Division and Multi-Market Power Division (“MPD”). Further, IPS was split, with portions remaining in MPD and portions moving to the new Integrated Circuits Division within AMG. Management performed a goodwill impairment analysis on the divisions (which were the reporting units) prior to and after the reorganization and did not identify an impairment.

Revenue and gross profit for the Company’s operating and reportable segments were as follows (in millions):

(1) During the first quarter of 2024, the Company reorganized certain reporting units and its segment reporting structure. As a result of the reorganization of divisions within PSG and AMG, the prior-period amounts have been reclassified to conform to current-period presentation.

The Company operates in various geographic locations. Sales to external customers have little correlation to where products are manufactured or the location of the end-customers. The Company believes it is, therefore, not meaningful to present operating profit by geographical location.

The following table illustrates the product technologies under each of the Company's reportable segments based on the Company's operating strategy. Because many products are sold into different end-markets, the total revenue reported for a segment is not indicative of actual sales in the end-market associated with that segment, but rather is the sum of the revenue from the product lines assigned to that segment. These segments represent the Company's view of the business and, as such, are used to evaluate progress of major initiatives and allocation of resources.

The Company does not discretely allocate assets to its operating segments, nor does management evaluate operating segments using discrete asset information. The Company’s consolidated assets used in manufacturing are generally shared across and are not specifically ascribed to operating and reportable segments. In situations where the carrying amounts assigned to an asset group needs to be evaluated for recoverability, judgment is used to determine the carrying amounts of the asset group based on the facts and circumstances.

Revenue

The Company's revenue is derived primarily from product sales, and to a much lesser extent, from manufacturing services and product development agreements. Revenue recognized from product sales as a percentage of total revenue was approximately 99%, 97% and 98% for the years ended December 31, 2024, 2023 and 2022, respectively. Revenue recognized from manufacturing services and product development agreements as a percentage of total revenue was approximately 1%, 3% and 2% for the years ended December 31, 2024, 2023 and 2022, respectively.

Remaining Performance Obligations

A portion of the Company’s orders are firm commitments that are non-cancelable, including certain orders or contracts with a duration of less than one year. Certain of the Company's customer contracts are multi-year agreements that include committed amounts ("Long-term Supply Agreements" or "LTSAs") for which the remaining performance obligations as of December 31, 2024 were approximately $11.9 billion (excluding the remaining performance obligations for contracts having a duration of one year or less). If products are shipped according to the terms of these contracts, the Company expects to recognize approximately 35% of this amount as revenue during the next twelve months. Total revenue estimates are based on negotiated contract prices and demand quantities, and could be influenced by risks and uncertainties, including manufacturing or supply chain constraints, modifications to customer agreements, and regulatory changes, among other factors. The timing, pricing or amounts of products delivered under LTSAs may be modified or canceled in circumstances upon mutual agreement, and the actual revenue recognized for the remaining performance obligations in future periods may significantly fluctuate from current estimates.

Certain LTSAs include non-cancelable capacity payments from the customer, which are generally due within 30 days of

agreement. These payments reserve production availability or are prepayments for the same purpose and are not recognized as revenue until the performance obligations are satisfied. Payments received in advance of the satisfaction of performance obligations are recorded as contract liabilities. During the years ended December 31, 2024 and 2023, $110.9 million and $88.2 million, respectively, were recognized as revenue for satisfying the associated performance obligations.

Note 4: Recent Accounting Pronouncements and Other Developments

Adopted

Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("ASU 2023-07")

In November 2023, the FASB issued ASU 2023-07 to enhance disclosures about significant segment expenses. The amendments in this ASU require a public entity to disclose significant segment expenses and other segment items on an annual and interim basis and to provide in interim periods all disclosures about a reportable segment's profit or loss and assets that are currently required annually. The amendments in this ASU also clarify circumstances in which an entity can disclose multiple segment measures of profit or loss and provide new segment disclosure requirements for entities with a single reportable segment. For public business entities, the provisions of ASU 2023-07 are effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. ASU 2023-07 was adopted for the year ended December 31, 2024 retrospectively to all periods presented in the financial statements. See Note 3: ''Segments and Revenue'' for additional information.

Pending Adoption

Income Statement (Subtopic 220-40): Reporting Comprehensive Income - Expense Disaggregation Disclosures ("ASU 2024-03")

In November 2024, the FASB issued ASU 2024-03, which requires public business entities to expand disclosures about specific expense categories. The amendments in this ASU require a public entity to disclose, in tabular format, in the notes to the financial statements, specific information about certain costs and expenses. Although the ASU does not change the expense captions an entity presents on the face of the income statement, it requires disaggregation of certain expense captions into specified categories. For public business entities, the provisions of ASU 2024-03 are effective for fiscal years beginning after December 15, 2026. Early adoption is permitted. Management is currently evaluating the requirements under this new standard.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09")

In December 2023, the FASB issued ASU 2023-09 to enhance disclosures about income taxes. The amendments in this ASU require a public entity to disclose in tabular format, using both percentages and reporting currency amounts, specific categories in the rate reconciliation and to provide additional information for reconciling items that meet a quantitative threshold. The amendments in this ASU also require taxes paid (net of refunds received) to be disaggregated by federal, state, and foreign taxes and further disaggregated for specific jurisdictions to the extent the related amounts exceed a quantitative threshold. For public business entities, the provisions of ASU 2023-09 are effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. Management is currently evaluating the requirements under this new standard.

SEC Climate Disclosure

In March 2024, the SEC issued final rules requiring registrants to include comprehensive climate-related disclosures in annual reports and registration statements. As adopted, the final rules require large accelerated filers to make their first climate-related disclosures for fiscal years beginning in 2025. However, in April 2024, the SEC issued an order voluntarily staying the effectiveness of the new rules pending the completion of judicial review of certain legal challenges to their validity. Management is currently evaluating these rules as adopted while monitoring the status of the related litigation and the SEC’s stay.

Note 5: Acquisitions and Divestitures

The Company pursues acquisitions and divestitures from time to time to leverage its existing capabilities and further expand its business to achieve certain strategic goals. Acquisition costs are not included as components of consideration transferred and instead are accounted for as expenses in the period in which the costs are incurred. During the year ended December 31, 2024, the Company incurred acquisition and divestiture-related costs of approximately $13.1 million, an insignificant amount during the year ended 2023 and approximately $12.9 million during the year ended 2022, which were included in operating expenses in the Consolidated Statements of Operations and Comprehensive Income.

2024 Acquisition

In July 2024, the Company completed its acquisition of SWIR Visions Systems ("SWIR") within its ISG segment for cash consideration of approximately $20.5 million. SWIR commercialized quantum-dot-based infrared image sensors, making them a strategic addition to the Company's existing technologies.

2022 Acquisition and Divestitures

EFK Acquisition

On December 31, 2022, the Company completed the acquisition of the East Fishkill, New York site and fabrication facility ("EFK") and certain other assets and liabilities from GLOBALFOUNDRIES U.S. Inc. ("GFUS"), previously announced in April 2019, for total consideration of $406.3 million, which was accounted for as a business combination. The Company paid GFUS $100.0 million and $70.0 million during 2020 and 2019, respectively, and the remaining consideration of $236.3 million was paid on January 3, 2023. Separately, the Company paid GFUS a one-time license fee of $30.0 million in cash for certain technology during 2019, which has been recognized as an intangible asset subject to amortization.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

During the year ended December 31, 2023, the Company finalized its determination relating to the fair value of assets acquired and liabilities assumed from the EFK acquisition, which was completed on December 31, 2022. The final allocation of the purchase price of EFK to the assets acquired and liabilities assumed, based on their relative fair values, which was materially consistent with the preliminary allocation, was as follows (in millions):


	Purchase Price Allocation
Inventories	$	3.3
Other current assets	4.4
Property, plant and equipment	396.5
Other non-current assets	11.4


Total assets acquired	415.6
Current liabilities	3.0
Other long-term liabilities	6.3
Total liabilities assumed	9.3
Net assets acquired/purchase price	$	406.3

Unaudited pro-forma consolidated results of operations are not included considering the significance of the acquisition to the results of the Company.

Divestitures

During 2022, the Company divested four wafer manufacturing facilities to various parties:

•the Oudenaarde, Belgium manufacturing facility was divested to BelGaN Group BV for an aggregate consideration of approximately $19.9 million;

•the South Portland, Maine, manufacturing facility was divested to Diodes Incorporated for an aggregate consideration of approximately $80.0 million;

•the Pocatello, Idaho manufacturing facility was divested to LA Semiconductor for an aggregate consideration of approximately $80.0 million; and

•the Niigata, Japan manufacturing facility was divested to JS Foundry K.K., a Japan-based foundry company, for aggregate consideration of approximately $90.3 million.

These divestiture transactions resulted in a net gain on divestiture of $67.0 million in 2022.

Note 6: Goodwill and Intangible Assets

Goodwill

Goodwill is tested for impairment annually on the first day of the fourth quarter or more frequently if events or changes in circumstances (each, a "triggering event") would more-likely-than-not reduce the fair value of a reporting unit below its carrying value.

As a result of the segment reorganization during the first quarter of 2024 discussed in Note 3: ''Segments and Revenue,'' management performed a goodwill impairment analysis on the divisions (which were the reporting units) prior to and after the reorganization and did not identify an impairment. In connection with the reorganization, the Company changed its reporting unit structure, which resulted in the reallocation of $25.9 million of goodwill from PSG to AMG based on the relative fair values of the businesses transferred.

During the year ended December 31, 2022, the Company recorded $330.0 million of goodwill impairment charges and $56.8 million of intangible impairment charges related to the exit of QCS. As of December 31, 2022, QCS had no remaining goodwill or intangible asset balances.

Year ended December 31, 2024:

2024 Business Realignment

During 2024, to further align with the "Fab Right" manufacturing strategy and consolidate its global footprint, the Company announced a restructuring plan that impacted approximately 1,500 employees. Approximately 1,200 employees were notified of their employment termination and around 300 additional employees were relocated to another onsemi site. The Company continues to evaluate employee positions and locations for potential operating improvements and efficiencies.

In connection with these actions, the Company expects to incur severance costs, related benefit expenses and other ancillary charges totaling approximately $77.9 million, of which approximately $75.7 million was recognized during the year ended December 31, 2024. Certain of the employees notified of their employment termination are required to render future service beyond a minimum retention period in order to receive severance benefits, and the related expense will be recognized ratably over the respective service periods.

Of the aggregate expenses relating to the actions announced in 2024, the Company paid approximately $39.5 million to approximately 1,100 terminated employees and had approximately $48.3 million accrued as of December 31, 2024. The remaining employees subject to this realignment are expected to be relocated or terminated and substantially all applicable severance and related benefit payments are expected to be paid over the next 12 months.

Year ended December 31, 2023:

2023 Business Realignment

During 2023, the Company announced the elimination of approximately 1,900 jobs in an effort to realign its operating models, drive organizational effectiveness and efficiencies, increase collaboration within its AMG (formerly "ASG") operating segment and IT support organizations, and right-size its workforce to consolidate manufacturing resources into fewer, common sites across the world to align with the next phase of the Company's multi-year "Fab Right" manufacturing strategy. As a result, AMG ceased its design and test operations in certain locations and there were changes in the IT operating model by transferring selected IT functions to strategic service providers. In connection with these actions, severance costs, related benefit expenses and other ancillary charges of $59.1 million were recorded during the year ended December 31, 2023.

Of the aggregate expense, during the years ended December 31, 2024 and 2023, the Company paid $11.1 million and $41.9 million, respectively, in connection with the approximately 1,600 employees who exited and $6.1 million remained accrued as of December 31, 2024.

Year ended December 31, 2022:

QCS wind down

On September 16, 2022, the Board of Directors approved an exit plan to wind down QCS as part of its ongoing efforts to focus on growth drivers and key markets, and to streamline its operations. As part of the exit plan, during the third quarter of 2022, the Company notified approximately 330 employees of their employment termination and incurred severance costs and other benefits of approximately $12.7 million. Approximately 304 employees exited during 2022 and the remaining employees exited during 2023.

In connection with the exit plan, the Company recorded $18.9 million of exit costs, which primarily relate to contract cancellation charges and litigation charges. The Company impaired $8.0 million of property, plant and equipment as well as $10.6 million of other miscellaneous assets. The Company recorded inventory reserves associated with the QCS wind down of $24.5 million, which was recorded in cost of revenue.

Long-Term Debt Activity

In 2023, the Company repaid $119.6 million of the remaining outstanding principal amount of the 1.625% Notes in cash and settled the excess over the principal amount by issuing 4.5 million shares of our common stock, which resulted in $422.0 million being recorded to additional paid-in capital and treasury stock, with no overall impact to equity. In 2024, all outstanding warrants related to the 1.625% Notes were settled entirely during the first quarter. See Note 10: ''Earnings Per Share and Equity'' for additional information regarding the warrant settlement.

In 2023, the Company entered into a new $1.5 billion Revolving Credit Facility.

In 2023, the Company completed the offering of $1.5 billion aggregate principal amount of its 0.50% Notes and utilized the net proceeds along with cash generated from operations to (i) repay $1,086.0 million of the outstanding indebtedness under the Term Loan “B” Facility and the related transaction fees and expenses and (ii) pay the $171.5 million net cost of the related convertible note hedges after such costs were offset by the proceeds from the sale of warrants.

Revolving Credit Facility

As of December 31, 2024, the Company had approximately $1,125.0 million available under the Revolving Credit Facility for future borrowings, except for amounts utilized for the letters of credit. Future borrowings are available for general corporate purposes, including working capital, capital expenditures, and acquisitions, but also include a $25.0 million sub-limit for the issuance of letters of credit and a foreign currency sub-limit of $75.0 million.

The maturity date for the borrowings under the Credit Agreement is June 22, 2028. Interest is payable based on either Secured Overnight Financing Rate (“SOFR”) or base rate options, as established at the commencement of each borrowing period, plus an applicable rate that varies based on the total leverage ratio. Lenders are owed certain fees, including a commitment fee that varies based on the total leverage ratio. The Company may prepay loans under the Credit Agreement at any time, in whole or in part, upon payment of accrued interest and break funding payments, if applicable.

The obligations are guaranteed by certain of the Company’s domestic subsidiaries and SCI LLC and are collateralized by, among other things, a pledge of the equity interests in certain of the Company’s and SCI LLC’s domestic subsidiaries and

material first tier foreign subsidiaries. The affirmative and negative covenants are customary for credit agreements of this nature. The Credit Agreement contains customary events of default, the occurrence of which could result in the acceleration of the associated obligations. The financial covenant relates to a maximum total net leverage ratio of 4.00 to 1.00 calculated using the consolidated total indebtedness to consolidated earnings before interest, taxes, depreciation and amortization and other adjustments for the trailing four consecutive quarters. The Company was in compliance with the total net leverage ratio as of December 31, 2024.

0.50% Notes and 0% Notes

The 0.50% Notes and 0% Notes are convertible and will mature on March 1, 2029 and May 1, 2027, respectively, unless earlier repurchased or redeemed by the Company or converted pursuant to their terms. The maximum number of shares of common stock issuable in connection with the conversion of the 0.50% Notes and 0% Notes is approximately 19.1 million and 21.7 million, respectively. As of December 31, 2024, neither the 0.50% Notes nor the 0% Notes were eligible for conversion by noteholders and as such, the 0% Notes were reclassified from current to long-term as of December 31, 2024. On or after the first business day of the month immediately prior to each note’s respective maturity date, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders of the notes may convert all or a portion of their respective notes at any time.

The Company may redeem for cash all or any portion of the notes, at the Company’s option, on or after March 6, 2026 and May 1, 2024 in the case of the 0.50% Notes and 0% Notes, respectively, if the last reported sale price of the Company’s common stock has been at least 130% ($135.03 and $68.86 for the 0.50% Notes and 0% Notes, respectively) of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading-day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides the related notice of redemption at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. The Company has not elected to redeem any portion of the 0% Notes. Prior to the respective dates upon which the holders may convert their notes at any time, the holders may convert their notes at their option only under the following circumstances: (i) during any calendar quarter commencing after the calendar quarter ending on December 31, 2024 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (ii) during the five consecutive business-day period after any five consecutive trading-day period in which the trading price per $1,000 principal amount of the notes for each trading day of such period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; (iii) if the Company calls any or all of the notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or (iv) upon the occurrence of specified corporate transactions described in each note's respective indenture agreement. The if-converted value of the 0% Notes exceeded its principal amount by $153.2 million as of December 31, 2024, calculated using the stock price on that date.

The Company also entered into warrant transactions with certain other financial institutions, whereby the Company sold warrants to acquire 14.4 million and 15.2 million shares of the Company's common stock with respect to the 0.50% Notes and 0% Notes, respectively. The number of shares of the Company’s common stock acquired for each sale of warrants is the same covered by the associated convertible note. The maximum number of shares of common stock issuable in connection with the warrants is approximately 28.9 million and 30.4 million with respect to the 0.50% Notes and 0% Notes, respectively.

In addition, for the 0.50% Notes and 0% Notes, the Company entered into convertible note hedge transactions with respect to the common stock with the initial purchasers or their affiliates and certain other financial institutions. The Company will exercise the note hedges simultaneously when the notes are settled. The convertible note hedges cover, subject to customary anti-dilution adjustments, the number of shares of common stock that initially underlie the associated note and that are expected to reduce the potential dilution to the common stock and/or offset potential cash payments in excess of the principal amount upon conversion of the notes.

The Company analyzed both the warrant and convertible note hedge transactions under ASC 815-40 - "Derivatives and Hedging - Contracts in Entity's Own Equity" and determined that the instruments met the criteria for classification as an equity transaction with no subsequent remeasurement.

See Note 10: ''Earnings Per Share and Equity'' for more information regarding outstanding warrants and convertible note hedges.

Earnings Per Share

Net income per share of common stock attributable to ON Semiconductor Corporation is shown below (in millions, except per share data):


	Year ended December 31,
	2024		2023		2022
Net income for basic earnings per share of common stock	$	1,572.8	$	2,183.7	$	1,902.2
Add: Interest on 1.625% Notes	—		1.3		2.0
Net income for diluted earnings per share of common stock	$	1,572.8	$	2,185.0	$	1,904.2

Basic weighted-average shares of common stock outstanding	427.4		430.7		433.2
Dilutive effect of share-based awards	0.6		1.2		1.8
Dilutive effect of convertible notes and warrants	4.7		14.9		13.2
Diluted weighted average shares of common stock outstanding	432.7		446.8		448.2

Net income per share of common stock:
Basic	$	3.68	$	5.07	$	4.39
Diluted	$	3.63	$	4.89	$	4.25

Basic income per share of common stock is computed by dividing net income attributable to the Company by the weighted average number of shares of common stock outstanding during the period. To calculate the diluted weighted-average shares of common stock outstanding, treasury stock method has been applied to calculate the number of incremental shares from the assumed issuance of shares relating to RSUs. The excluded number of anti-dilutive share-based awards was approximately 0.5 million, 0.1 million and 0.3 million for the years ended December 31, 2024, 2023 and 2022, respectively.

The dilutive impact related to the Company’s 0.50% Notes and 0% Notes has been calculated using the if-converted method. The 0.50% Notes and the 0% Notes are repayable in cash up to the par value and in cash or shares of common stock for the excess over par value.

Prior to conversion, the convertible note hedges are not considered for purposes of the earnings per share calculations, as their effect would be anti-dilutive. Upon conversion, the convertible note hedges are expected to offset the dilutive effect of the 0.50% Notes and 0% Notes when the stock price is above $103.87 and $52.97 per share, respectively.

The dilutive impact of the warrants issued concurrently with the issuance of the 0.50% Notes and 0% Notes with exercise prices of $156.78 and $74.34, respectively, has been included in the calculation of diluted weighted-average common shares outstanding, if applicable.

Warrants Settlement

At the time of issuance of the 1.625% Notes, the Company sold warrants to bank counterparties whereby the holders of the warrants had the option to purchase the equivalent number of shares of the Company’s common stock at a price of $30.70 per share from the Company beginning on January 16, 2024. The bank counterparties exercised 6.7 million warrants during the first quarter of 2024, and the Company settled them by issuing 4.0 million shares of common stock on a net-share basis based on the average stock price on the day of exercise, for which no cash was exchanged. All outstanding warrants related to the 1.625% Notes were settled entirely during the quarter ended March 29, 2024.

In February 2023, the Board of Directors approved a new share repurchase program (the “Share Repurchase Program”) under which the Company may repurchase up to an aggregate of $3.0 billion of the Company's common stock (exclusive of fees, commissions and other expenses). Under the Share Repurchase Program, which does not require the Company to purchase any minimum amount of common stock or at all, the Company may repurchase shares from February 8, 2023 through December 31, 2025. The repurchases under the Share Repurchase Program amounted to $650 million and $564 million for the year ended December 31, 2024 and 2023, respectively, excluding fees, commissions and excise tax.

Share-based compensation expense, net of taxes	$	107.5	$	95.7	$	79.6

As of December 31, 2024, total unrecognized share-based compensation expense, net of estimated forfeitures, related to non-vested RSUs with service, performance and market conditions was $150.0 million, which is expected to be recognized over a weighted-average period of 1.6 years. Upon vesting of RSUs, stock grant awards or completion of a purchase under the ESPP, the Company issues new shares of common stock.

Share-Based Compensation Information

The fair value per unit of each RSU and stock grant award is determined on the grant date. Share-based compensation expense is based on awards ultimately expected to vest. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The annualized pre-vesting forfeitures for RSUs were estimated to be approximately 8% for the years ended December 31, 2024, 2023 and 2022.

Plan and Award Descriptions

On March 23, 2010, the Company adopted the Amended and Restated SIP which has been subsequently amended over the years primarily to increase the number of shares of common stock subject to all awards. Generally, RSUs granted under the Amended and Restated SIP vest ratably over three years for awards with service conditions and over two, three, or five years for awards with performance or market conditions, or a combination thereof, and are settled in shares of the Company's common stock upon vesting. Generally, upon the termination of an RSU holder's employment, all unvested RSUs will immediately cancel, except under circumstances where the service condition has been fulfilled.

On May 20, 2021, the Company's stockholders approved certain amendments to the Amended and Restated SIP to extend the expiration date from 2022 to 2031 and to increase the number of shares of common stock subject to all awards by 22.5 million to 109.5 million. As of December 31, 2024, there was an aggregate of 33.6 million shares of common stock available for grant under the Amended and Restated SIP.

The RSUs awarded during 2024 include RSUs that vest upon satisfaction of service conditions and 0.9 million RSUs granted to certain officers and employees of the Company that vest upon the achievement of certain performance criteria and market conditions. The number of units expected to vest is evaluated each reporting period and compensation expense is recognized for those units for which achievement of the performance criteria is considered probable. Compensation expense for RSUs with market conditions is recognized based on the grant date fair value irrespective of the achievement of the condition. The fair values of the vested awards are based on the stock price as of the vesting dates, and during the years ended December 31, 2024, 2023 and 2022 totaled $142.9 million, $202.6 million and $232.8 million, respectively.

As of December 31, 2024, unrecognized compensation expense, net of estimated forfeitures related to non-vested RSUs granted under the Amended and Restated SIP with service, performance and market conditions, was $100.6 million, $12.6 million and $36.8 million, respectively. For RSUs with time-based service conditions, expense is being recognized over the vesting period; for RSUs with performance criteria, expense is recognized over the period when the performance criteria is expected to be achieved; for RSUs with market conditions, expense is recognized over the period in which the condition is assessed irrespective of whether it would be achieved or not. Unrecognized compensation cost for awards with certain performance criteria that are not expected to be achieved is not included here. Total compensation expense related to service-based, performance-based and market-based RSUs was $128.4 million for the year ended December 31, 2024, which included $75.1 million for RSUs with time-based service conditions that were granted in 2024 and prior that are expected to vest.

As of December 31, 2024, there were approximately 6.9 million shares available for issuance under the ESPP. Total compensation expense related to the ESPP for the year ended December 31, 2024 was $7.7 million.

Note 12: Employee Benefit Plans

Defined Benefit Pension Plans

The Company maintains defined benefit pension plans for employees of certain of its foreign subsidiaries. Such plans conform to local practice in terms of providing minimum benefits mandated by law, collective agreements or customary practice. The Company recognizes the aggregate amount of all overfunded plans as assets and the aggregate amount of all underfunded plans as liabilities in its Consolidated Balance Sheets. The Company's expected long-term rate of return on plan assets is updated at least annually, taking into consideration its asset allocation, historical returns on similar types of assets and the current economic environment. For estimation purposes, the Company assumes its long-term asset mix will generally be consistent with the current mix. The Company determines its discount rates using highly rated corporate bond yields and government bond yields.

Benefits under all of the plans are valued utilizing the projected unit credit cost method. The Company's policy is to fund its

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

defined benefit plans in accordance with local requirements and regulations. The funding is primarily driven by the current assessment of the economic environment and projected benefit payments of foreign subsidiaries. The measurement date for determining the defined benefit obligations for all plans is December 31 of each year.

The Company recognizes actuarial gains and losses during the period that the Company's annual pension plan actuarial valuations are prepared, which generally occurs during the fourth calendar quarter of each year, or during any interim period where a revaluation is deemed necessary. The Company recognized an actuarial gain of $12.2 million for the year ended December 31, 2024, an actuarial loss of $4.0 million for the year ended December 31, 2023 and an actuarial gain of $22.1 million for the year ended December 31, 2022. Of the actuarial gain for 2024, $9.5 million was primarily due to an increase in the discount rates and plan expense and $2.7 million was due to higher-than-expected returns on plan assets.

The following tables summarize the status of the Company's foreign defined benefit pension plans and the net periodic pension cost (dollars in millions):

Plan Assets

The Company's overall investment strategy is to focus on stable and low credit risk investments aimed at providing a positive rate of return to the plan assets. The Company has an investment mix with a wide diversification of asset types and fund strategies that are aligned with each region and foreign location's economy and market conditions. Investments in government securities are generally guaranteed by the respective government offering the securities. Investments in corporate bonds, equity securities, and foreign mutual funds are made with the expectation that these investments will give an adequate rate of long-term returns despite periods of high volatility. Other types of investments include investments in cash deposits, money market funds and insurance contracts. Asset allocations are based on the anticipated required funding amounts, timing of benefit payments, historical returns on similar assets and the influence of the current economic environment.

The following table sets forth, by level within the fair value hierarchy, a summary of investments measured at fair value and the asset allocations of the plan assets in the Company's foreign pension plans (in millions):

Environmental Contingencies

The Company currently leases its headquarters in Scottsdale, Arizona on Salt River Maricopa Indian Community property.

Though the Company has encountered and dealt with a number of environmental issues over time relating to the various locations that comprise its operations, any costs to the Company in connection with such matters have not been, and, based on the information available, are not expected to be material.

The following presents a summary of such environmental contingencies:

•East Greenwich, Rhode Island. The Company’s design center in East Greenwich, Rhode Island is located on property that has localized soil contamination. In connection with the purchase of the facility, the Company entered into a Settlement Agreement and Covenant Not to Sue with the State of Rhode Island. This agreement requires that remedial actions be undertaken and a quarterly groundwater monitoring program be initiated by the former owners of the property.

•Santa Clara, California. As a result of the acquisition of AMIS in 2008, the Company is a "primary responsible party" to an environmental remediation and clean-up plan at AMIS’s former corporate headquarters in Santa Clara, California. Costs incurred by AMIS include implementation of the clean-up plan, operations and maintenance of remediation systems, and other project management costs. However, AMIS’s former parent company, a subsidiary of Nippon Mining, contractually agreed to indemnify AMIS and the Company for any obligations relating to environmental remediation and clean-up activities at this location. This facility was divested to Lincoln Property Company Commercial, Inc. in 2022.

•South Portland, Maine. Through its acquisition of Fairchild, the Company acquired a facility in South Portland, Maine. This facility was divested to Diodes, Inc. in 2022. This facility has ongoing environmental remediation projects to respond to certain releases of hazardous substances that occurred prior to the leveraged recapitalization of Fairchild from its former parent company, National Semiconductor Corporation, which is now owned by TI. To the extent the Company could still incur liabilities with respect to these remediation projects, pursuant to a 1997 asset purchase agreement entered into in connection with the Fairchild recapitalization, National Semiconductor Corporation agreed to indemnify Fairchild, without limitation and for an indefinite period of time, for all future costs related to these projects.

•Bucheon, South Korea. Under a 1999 asset purchase agreement pursuant to which Fairchild purchased the power device business of Samsung, Samsung agreed to indemnify Fairchild in an amount up to $150.0 million for remediation costs and other liabilities related to historical contamination at Samsung’s Bucheon, South Korea operations.

•Mountain Top, Pennsylvania. Under a 2001 asset purchase agreement pursuant to which Fairchild purchased a manufacturing facility in Mountain Top, Pennsylvania, Intersil Corp. (subsequently acquired by Renesas Electronics Corporation) agreed to indemnify Fairchild for remediation costs and other liabilities related to historical contamination at the facility.

•Hartford, Illinois. The Company was notified by the EPA that it has been identified as a PRP under the Comprehensive Environmental, Response, Compensation, and Liability Act in the Chemetco Superfund matter. Chemetco, a defunct reclamation services supplier that operated in Hartford, Illinois at what is now a Superfund site, has performed reclamation services for the Company in the past. The EPA is pursuing Chemetco customers for contribution to the site clean-up activities. The Company has joined a PRP group, which is cooperating with the EPA in the evaluation and funding of the clean-up activities.

Financing Contingencies

In the ordinary course of business, the Company provides standby letters of credit or other guarantee instruments to certain parties initiated by either the Company or its subsidiaries, as required for transactions, including, but not limited to, material purchase commitments, agreements to mitigate collection risk, leases, utilities or customs guarantees. As of December 31, 2024, the Company's Revolving Credit Facility included $25.0 million available for the issuance of letters of credit. There were $0.9 million letters of credit outstanding under the Revolving Credit Facility as of December 31, 2024, which reduced the Company's borrowing capacity. The Company also had outstanding guarantees and letters of credit outside of its Revolving Credit Facility totaling $6.6 million as of December 31, 2024.

As part of obtaining financing in the ordinary course of business, the Company issued guarantees related to certain of its subsidiaries, which totaled $0.9 million as of December 31, 2024. Based on historical experience and information currently available, the Company believes that it will not be required to make payments under the standby letters of credit or guarantee arrangements for the foreseeable future.

Indemnification Contingencies

The Company is a party to a variety of agreements entered into in the ordinary course of business, including acquisition agreements, pursuant to which it may be obligated to indemnify the other parties for certain liabilities that arise out of or relate to the subject matter of the agreements. Some of the agreements entered into by the Company require it to indemnify the other party against losses due to IP infringement, property damage (including environmental contamination), personal injury, failure to comply with applicable laws, the Company’s negligence or willful misconduct or breach of representations and warranties and covenants related to such matters as title to sold assets. In the case of certain acquisition agreements, these agreements may require us to maintain such indemnification provisions for the acquiree’s directors, officers and other employees and agents, in certain cases for a number of years following the acquisition.

The Company faces risk of exposure to warranty and product liability claims in the event that its products fail to perform as expected or such failure of its products results, or is alleged to result, in economic damage, bodily injury or property damage. In addition, if any of the Company’s designed products are alleged to be defective, the Company may be required to participate in their recall. Depending on the significance of any particular customer and other relevant factors, the Company may agree to provide more favorable rights to such customer for valid defective product claims.

The Company and its subsidiaries provide for indemnification of directors, officers and other persons in accordance with limited liability company operating agreements, certificates of incorporation, by-laws, articles of association or similar organizational documents, as the case may be. Section 145 of the Delaware General Corporation Law ("DGCL") authorizes a court to award, or a corporation’s board of directors to grant, indemnity to directors and officers under certain circumstances and subject to certain limitations. The terms of Section 145 of the DGCL are sufficiently broad to permit indemnification under certain circumstances for liabilities, including reimbursement of expenses incurred, arising under the Exchange Act. As permitted by the DGCL, the Company’s Amended and Restated Certificate of Incorporation (as amended, the "Certificate of Incorporation") contains provisions relating to the limitation of liability and indemnification of directors and officers. The Certificate of Incorporation eliminates the personal liability of each of the Company’s directors to the fullest extent permitted by Section 102(b)(7) of the DGCL, as it may be amended or supplemented, and provides that the Company will indemnify its directors and officers to the fullest extent permitted by Section 145 of the DGCL, as amended from time to time.

ON SEMICONDUCTOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company has entered into indemnification agreements with each of its directors and executive officers. The form of agreement (the "Indemnification Agreement") provides, subject to certain exceptions and conditions specified in the Indemnification Agreement, that the Company will indemnify each indemnitee to the fullest extent permitted by Delaware law against all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with a proceeding or claim in which such person is involved because of his or her status as one of the Company’s directors or executive officers. In addition, the Indemnification Agreement provides that the Company will, to the extent not prohibited by law and subject to certain exceptions and repayment conditions, advance specified indemnifiable expenses incurred by the indemnitee in connection with such proceeding or claim.

The Company also maintains directors’ and officers’ insurance policies that indemnify its directors and officers against various liabilities, including certain liabilities under the Exchange Act, which might be incurred by any director or officer in his or her capacity as such.

While the Company’s future obligations under certain agreements may contain limitations on liability for indemnification, other agreements do not contain such limitations and under such agreements it is not possible to predict the maximum potential amount of future payments due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under any of these indemnities have not had a material effect on the Company’s business, financial condition, results of operations or cash flows. Additionally, the Company does not believe that any amounts that it may be required to pay under these indemnities in the future will be material to the Company’s business, financial position, results of operations, or cash flows.

Government Assistance

2024 Government Incentives

The Company receives government incentives from U.S. federal and state governments and non-U.S. governments in the form of cash grants and tax abatements, which in most cases, attach conditions for a specific duration period, generally related to hiring, training and/or retaining employees, the construction or acquisition of assets and placing them in service or the development of specific technologies. If conditions are not satisfied or the duration period for the agreement is infringed, the incentives are subject to reduction, termination, or recapture.

As of December 31, 2024, relating to government incentives, $86.3 million and $2.4 million were included in other current assets and other non-current assets, respectively, substantially all of which represents the benefit of investment tax credits in excess of taxes payable. As December 31, 2024, $104.4 million was recorded as a net decrease to property, plant and equipment, net. Additionally, $10.8 million and $5.3 million were recorded as a reduction to cost of revenue and operating expenses, respectively, for the year ended December 31, 2024.

The duration of the agreements for the incentives received by the Company in 2024 ranges from one to twenty years, with a recapture period that can extend up to ten years.

2023 Government Incentives

As of December 31, 2023, relating to government incentives, $12.9 million and $5.2 million were included in other current assets and other non-current assets, respectively, representing the amounts receivable, $80.4 million was recorded as a net decrease to property, plant and equipment, net, and $83.6 million was recorded as a reduction to taxes payable included in accrued expenses and other current liabilities. Additionally, $5.1 million and $4.9 million were recorded as a reduction to cost of revenue and operating expenses, respectively, for the year ended December 31, 2023.

2022 Government Incentives

During the year ended December 31, 2022, the Company received a nominal amount related to these programs. To the extent amounts have been received by the Company in advance of the completion of the conditions, they have been recorded as a liability.

Legal Matters

From time to time, the Company is party to various legal proceedings arising in the ordinary course of business, including indemnification claims, claims of alleged infringement of patents, trademarks, copyrights and other IP rights, claims of alleged non-compliance with contract provisions and claims related to alleged violations of laws and regulations. The Company evaluates the status of the legal proceedings in which it is involved to assess whether a loss is reasonably estimable and either remote, reasonably possible or probable of occurring. The Company further evaluates each legal proceeding to assess whether an estimate of possible loss or range of possible loss can be made for disclosure purposes. Although litigation is inherently unpredictable, the Company believes that it has adequate provisions for any probable and reasonably estimable losses. However, the Company’s estimates may not represent its maximum possible exposure in any particular legal proceeding. Legal expenses related to defense, negotiations, settlements, rulings and advice of outside legal counsel are expensed as incurred.

The Company is currently involved in a variety of legal matters that arise in the ordinary course of business. Based on information currently available, except as disclosed below (if any), the Company is not involved in any pending or threatened legal proceedings that it believes could reasonably be expected to have a material adverse effect on its financial condition, results of operations or liquidity. The litigation process is inherently uncertain, and the Company cannot guarantee that the outcome of any litigation matter will be favorable to the Company.

Securities Class Action and Derivative Litigation Concerning the Company's SiC Business

On December 13, 2023, a putative class action captioned Hubacek v. On Semiconductor Corp., et al., Case No. 1:23-cv-01429 (D. Del.) ("Hubacek"), was filed by an alleged stockholder of the Company in the U.S. District Court for the District of Delaware against the Company and certain of its officers. This action was transferred to the U.S. District Court for the District of Arizona in March of 2024. The initial complaint asserted claims for alleged violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. The initial complaint alleged that the defendants made misleading statements regarding the Company's SiC business. An amended complaint was filed on May 31, 2024. The amended complaint again asserts claims for alleged violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. The plaintiff seeks a ruling that this case may proceed as a class action, and seeks damages, attorneys’ fees and costs. The Company filed a motion to dismiss the amended complaint on July 30, 2024. Upon reviewing the Company’s motion to dismiss the amended complaint, plaintiff deemed it necessary to further amend their complaint. On September 6, 2024, plaintiff filed their second amended complaint. The Company filed its motion to dismiss this second amended complaint on October 10, 2024. Full briefing for this motion to dismiss the second amended complaint was completed on December 20, 2024. The Company expects the court to make a ruling on this motion to dismiss in the first half of 2025. The Company believes that it has strong legal defenses to the claims asserted, and will vigorously defend them.

On January 3, 2024, a purported stockholder derivative action captioned Silva v. El-Khoury, et al., Case No. 1:24-cv-00007 (D. Del.) ("Silva"), was filed by a purported stockholder of the Company in the U.S. District Court for the District of Delaware. On February 12, 2024, a purported stockholder derivative action captioned Smalley et al. v. El-Khoury et al. Case No. 1:24-cv-00183 (D. Del.) ("Smalley"), was filed by a purported stockholder of the Company in the U.S. District Court for the District of Delaware. Both aforementioned derivative actions, Silva and Smalley, were voluntarily dismissed without prejudice on April 15, 2024. On February 28, 2024, a purported stockholder derivative action captioned Mumme et al. v. El-Khoury et al. Case No. CV2024-003974 (D. AZ.) ("Mumme"), was filed by a purported stockholder of the Company in the Superior Court of the State of Arizona in and for the County of Maricopa and on March 15, 2024, a purported stockholder derivative action captioned Chan et al. v. Abe et al. Case No. 2:24-cv-00552 (D. AZ.) ("Chan"), was filed by a purported stockholder of the Company in the U.S. District Court for the District of Arizona. The allegations in these derivative complaints are substantially similar to the allegations in the securities class action complaint discussed above. The derivative suits purport to assert claims (1) on behalf of the Company against certain of its officers for contribution under the federal securities laws and (2) against all of the defendants for breach of fiduciary duty, aiding and abetting, unjust enrichment, abuse of control, gross mismanagement, and waste. The plaintiffs seek an award of damages, pre-judgment interest, punitive damages, attorneys’ fees, and other costs and expenses related to the litigation. The Company believes that the plaintiffs lack standing to assert claims on the Company’s behalf. These two pending derivative actions, Mumme and Chan, were stayed by court order, pending the resolution of Hubacek.

Intellectual Property Matters

The Company faces risk of exposure from claims of infringement of the IP rights of others. In the ordinary course of business, the Company receives letters asserting that the Company’s products or components breach another party’s rights. Such letters may request royalty payments from the Company, that the Company cease and desist using certain IP or other remedies.

Note 14: Fair Value Measurements

Fair Value of Financial Instruments

The following fair value tier level hierarchy is used to determine fair values of financial instruments:

•Level 1: based on observable inputs that reflect quoted prices for identical assets or liabilities in active markets.

•Level 2: based on inputs other than quoted prices included in Level 1 that are observable for the asset or liability either directly or indirectly.

•Level 3: based on the use of unobservable inputs for the assets and liabilities and other types of analyses.

The carrying value of cash and cash equivalents, which include money market funds and demand and time deposits, approximate fair value because of the short-term maturity of these instruments. The carrying amount of other current assets and liabilities, such as accounts receivable and accounts payable, approximates fair value due to the short-term maturity of the amounts, and such amounts are considered Level 2 in the fair value hierarchy.

The Company held $300.0 million of short-term investments in time deposits and an insignificant amount of cash equivalents in the form of time deposits and money market funds as of December 31, 2024. The Company held an insignificant amount of investments in money market funds and no cash equivalents in the form of demand deposits or time deposits or investments in other assets as of December 31, 2023. Money market funds and demand deposits are classified as Level 1, while time deposits are classified as Level 2 within the fair value hierarchy.

Fair Value of Long-Term Debt, including Current Portion

The carrying amounts and fair value of the Company’s long-term borrowings were as follows (in millions):


	As of December 31,
	2024				2023
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Long-term debt, including current portion (1):
Revolving Credit Facility	$	375.0	$	373.4	$	375.0	$	390.6
0.50% Notes	1,478.2		1,450.4		1,473.1		1,596.6
0% Notes	797.2		1,054.4		794.0		1,334.4
3.875% Notes	695.5		656.3		694.4		652.0

(1)Long-term debt is carried on the Consolidated Balance Sheets at historical cost net of debt discount and issuance costs.

The fair value of the 0% Notes, 0.50% Notes and 3.875% Notes was estimated based on market prices in active markets (Level 1), and the Revolving Credit Facility was estimated based on discounting the remaining principal and interest payments using current market rates for similar debt (Level 2).

Fair Values Measured on a Non-Recurring Basis

The Company's non-financial assets, such as property, plant and equipment, goodwill and intangible assets, are recorded at fair value upon a business combination and are remeasured at fair value only if an impairment charge is recognized. The Company uses unobservable inputs to the valuation methodologies that are significant to the fair value measurements, and the valuations require management's judgment due to the absence of quoted market prices. The Company determines the fair value of its held and used assets, goodwill and intangible assets using an income, cost or market approach as determined reasonable.

ON SEMICONDUCTOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

During the years ended December 31, 2024, 2023 and 2022, there were no non-financial assets included in the Company's Consolidated Balance Sheet that were remeasured at fair value on a non-recurring basis.

Note 15: Financial Instruments

Foreign Currencies

As a multinational business, the Company's transactions are denominated in a variety of currencies. When appropriate, the Company uses forward foreign currency contracts to reduce its overall exposure to the effects of currency fluctuations on its results of operations and cash flows. The Company's policy prohibits trading in currencies for which there are no underlying exposures and entering into trades for any currency to intentionally increase the underlying exposure. The Company primarily hedges existing assets and liabilities associated with transactions currently on its balance sheet, which are undesignated hedges for accounting purposes.

As of December 31, 2024 and 2023, the Company had outstanding foreign exchange contracts with notional amounts of $256.8 million and $262.2 million, respectively. Such contracts were obtained through financial institutions and were scheduled to mature within two months from the time of purchase. Management believes that these financial instruments should not subject the Company to increased risks from foreign exchange movements because gains and losses on these contracts should offset gains and losses on the underlying assets, liabilities and transactions to which they are related.

The following schedule summarizes the Company's net foreign exchange positions in U.S. dollars (in millions):


	As of December 31,
	2024				2023
	Buy (Sell)		Notional Amount		Buy (Sell)		Notional Amount

Amounts receivable or payable under the contracts were not material as of December 31, 2024 and 2023, and are included in other current assets or accrued expenses and other current liabilities in the accompanying Consolidated Balance Sheets. Realized and unrealized foreign currency transactions totaled a gain of $0.9 million for the year ended December 31, 2024 and a loss of $7.9 million and $0.7 million for the years ended December 31, 2023 and 2022, respectively. The realized and unrealized foreign currency transactions are included in other income (expense) in the Company's Consolidated Statements of Operations and Comprehensive Income.

Cash Flow Hedges

Foreign currency risk

During 2023, the Company entered into foreign currency forward contracts to hedge its exposure to foreign currency exchange rate risk related to future forecasted transactions denominated in certain currencies other than the U.S. dollar. These contracts generally mature within 12 months and are designated as cash flow hedges for accounting purposes.

As of December 31, 2024 and 2023, the notional value of outstanding foreign currency forward contracts designated as cash flow hedges was $145.1 million and $92.2 million, respectively, with a fair value of $8.2 million recorded as accrued expenses and other current liabilities for 2024 and $0.9 million recorded as other current assets for 2023. A loss of $10.0 million and $0.1 million was recognized as a component of cost of revenue for the years ended December 31, 2024 and 2023, respectively. The Company did not identify any ineffectiveness with respect to the notional amounts of the foreign currency forward contracts effective as of December 31, 2024.

Interest rate risk

During 2023, the Company terminated its interest rate swap agreements with a notional value of $500 million, received cash proceeds of $27.7 million, net of termination fees, and recognized $6.9 million of other income related to the termination. At the time of termination, approximately $20.7 million was recorded in accumulated other comprehensive loss, of which $11.9 million and $6.9 million were subsequently recognized as other income during the years ended December 31, 2024 and 2023, respectively, with the remaining portion recognized as part of the loss on debt refinancing and prepayment during 2023.

See Note 17: ''Changes in Accumulated Other Comprehensive Loss'' for the effective amounts related to derivative instruments designated as cash flow hedges affecting accumulated other comprehensive loss and the Consolidated Statements of Operations and Comprehensive Income for the year ended December 31, 2024.

Convertible Note Hedges

The Company entered into convertible note hedges in connection with the issuance of the 0% Notes, 0.50% Notes and 1.625% Notes. See Note 9: ''Long-Term Debt'' for more information.

Other

As of December 31, 2024, the Company had no outstanding commodity derivatives, currency swaps, options or equity investments held at subsidiaries or affiliated companies. The Company does not hedge the value of its equity investments in its subsidiaries or affiliated companies.

The Company is exposed to credit-related losses if its hedge counterparties fail to perform their obligations. As of December 31, 2024, the counterparties to the Company's hedge contracts were held at financial institutions which the Company believes to be highly rated, and no credit-related losses are anticipated.

The Company has investment tax credits, which are accounted for pursuant to ASC 740, in Korea and the Czech Republic. The Company uses the deferral method of accounting for investment tax credits under which the credits are recognized as reductions in the carrying value of the related assets. Deferred tax related to differences in GAAP versus tax carrying value is recorded pursuant to the gross-up method. Further, the Company analyzes the need for a valuation allowance related to these credits, and as of December 31, 2024, the Company recorded a partial valuation of $67.9 million against the Korea investment tax credits forecasted to expire unutilized. See Schedule II - "Valuation and Qualifying Accounts" included elsewhere in this Form 10-K.

As of December 31, 2024 and 2023, the Company had approximately $4.4 million and $22.2 million, respectively, of U.S. federal NOL carryforwards, before the impact of unrecognized tax benefits. The decrease is due to current year utilization. These NOL carryforwards can be carried forward indefinitely until utilized. As of December 31, 2024 and 2023, the Company had approximately $0.5 million and $6.6 million, respectively, of U.S. federal credit carryforwards, before consideration of the impact of unrecognized tax benefits and the valuation allowance. The credits will expire in 2033 if unutilized. These NOL and credit carryforwards relate to acquisitions and, consequently, are limited in the amount that can be utilized in any one year.

As of December 31, 2024 and 2023, the Company had approximately $245.7 million and $273.3 million, respectively, of U.S. state NOL carryforwards, before consideration of valuation allowance or the impact of unrecognized tax benefits. The decrease is primarily due to current year utilization. The U.S. state NOL carryforwards will expire in varying amounts from 2025 to 2041, if unutilized. As of December 31, 2024 and 2023, the Company had $110.2 million and $111.8 million, respectively, of U.S. state credit carryforwards before consideration of valuation allowance or the impact of unrecognized tax benefits. The U.S. state credits will expire in varying amounts beginning in 2025 while a substantial amount of the state credits carryforward indefinitely.

As of December 31, 2024 and 2023, the Company had approximately $244.1 million and $232.3 million, respectively, of foreign NOL carryforwards, before consideration of valuation allowance. The increase is primarily due to generation of NOLs. As of December 31, 2024 and 2023, the Company had $157.6 million and $93.5 million, respectively, of foreign credit carryforwards before consideration of valuation allowance. A significant portion of the foreign NOLs and credit carryforwards will expire in varying amounts prior to 2035, if unutilized.

The Company maintains a partial valuation allowance of $90.9 million, net of federal benefit on its U.S. state deferred tax assets, primarily NOLs and credits. The remaining valuation allowance of $125.3 million primarily relates to NOLs and tax

credits in certain other foreign jurisdictions that primarily expire in 2025.

As of December 31, 2024, the Company was not indefinitely reinvested with respect to the earnings of its foreign subsidiaries and has therefore accrued withholding taxes that would be owed upon future distributions of such earnings.

The activity for unrecognized gross tax benefits was as follows (in millions):


	2024		2023		2022
Balance at beginning of year	$	67.7	$	136.8	$	137.2

Additions for tax benefits related to the current year	5.2		3.4		3.3
Additions for tax benefits of prior years	1.4		0.7		0.5
Reductions for tax benefits of prior years	(22.3)		(48.0)		(0.3)
Lapse of statute	(4.0)		(9.9)		(3.8)
Settlements	(2.3)		(15.3)		(0.1)

Balance at end of year	$	45.7	$	67.7	$	136.8

Included in the December 31, 2024 balance of $45.7 million is $38.5 million related to unrecognized tax benefits that, if recognized, would affect the annual effective tax rate. Also included in the balance of unrecognized tax benefits as of December 31, 2024 is $7.2 million of benefit that, if recognized, would result in adjustments to other tax accounts, primarily deferred taxes. Although the Company cannot predict the timing of resolution with taxing authorities, if any, the Company believes it is reasonably possible that its unrecognized tax benefits will be reduced by $3.8 million in the next 12 months due to settlement with tax authorities or expiration of the applicable statute of limitations.

The Company recognizes interest and penalties accrued related to uncertain tax positions in tax expense in the Consolidated Statements of Operations and Comprehensive Income. The Company recognized approximately $1.6 million of net tax expense, $0.8 million of net tax benefit and $1.4 million of tax expense for interest and penalties during the year ended December 31, 2024, 2023 and 2022, respectively. The Company had approximately $3.6 million, $2.0 million, and $2.7 million of accrued interest and penalties as of December 31, 2024, 2023, and 2022, respectively.

The Company is currently under IRS examination for the 2022 and 2023 tax years. Tax years prior to 2021 are generally not subject to examination by the IRS. For state tax returns, the Company is generally not subject to income tax examinations for tax years prior to 2020. With respect to jurisdictions outside the United States, the Company is generally not subject to examination for tax years prior to 2014.

Note 19: Subsequent Events

On January 14, 2025, the Company completed the acquisition of the Silicon Carbide Junction Field-Effect Transistor ("SiC JFET") technology business from Qorvo US, Inc., and certain of its subsidiaries, for $118.8 million in cash, subject to working capital adjustments. The acquired SiC JFET technology expands the Company's EliteSiC power portfolio within the PSG reportable segment and enables the Company to help address the need for high energy efficiency and power density in the AC-DC stage in power supply units for AI data centers. Due to the timing of the transaction, a preliminary allocation of the purchase consideration to the assets acquired and liabilities assumed could not be provided, and is expected to be completed by the end of the first fiscal quarter of 2025.
