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 industry leading intelligent sensing and power solutions to help our customers solve the most challenging problems and create cutting edge products for a better future. 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, industrial power and storage systems. Our intelligent sensing technologies, supports 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.

onsemi’s intelligent power allows our customers to exceed range targets with lower weight and reduce system cost through efficiency. With our sensing integration, we believe onsemi’s intelligent power solutions achieve higher efficiencies compared to our peers and allows lower temperature operation, reducing cooling requirements, saving costs and minimizing weight while delivering the required power with less die per module and achieving higher range for a given battery capacity. onsemi’s intelligent sensing solutions offer proprietary features in smaller packages that support customers' use cases. We believe our intelligent sensing technology offers advanced features to achieve optimal results and our product integration drives improved efficiency. This performance is delivered in a smaller footprint while reducing system latency to increase safety and throughput by providing a proprietary feature set to solve different use cases.

We serve a broad base of end-user markets, including automotive, industrial and others which include communications, computing and consumer. We believe the evolution of automotive with advancements in autonomous driving, ADAS, vehicle electrification, and the increase in electronics content for vehicle platforms is reshaping the boundaries of transportation. With our extensive portfolio of AEC-qualified products, onsemi helps customers design high reliability solutions while delivering top performance. And within the industrial space, onsemi is helping OEMs develop innovative products to navigate the ongoing transformation across energy infrastructure, factory automation and power conversion.

As of December 31, 2021, we were organized into the following three operating and reportable segments: the Power Solutions Group ("PSG"), the Advanced Solutions Group ("ASG") and the Intelligent Sensing Group ("ISG").

Business Strategy Developments

Our primary focus continues to be on gross margin and operating margin expansion, while at the same time achieving revenue growth in our focused end-markets of automotive, industrial and communications infrastructure as well as being opportunistic in other end-markets, including obtaining longer-term supply arrangements with strategic end-customers. We are also focused on achieving efficiencies in our operating expenditures. While we believe we have made significant progress on gross margin and operating margin expansion, we continue to rationalize our product portfolio and have allocated capital, research and development investments and resources to accelerate growth in high-margin products and end-markets by moving away from non-differentiated products, which have had historically lower gross margins. To this effect, onsemi is exploring the sale of select manufacturing facilities. As actions are initiated to achieve our business strategy goals, we could incur accounting charges in the future.

We believe these actions, among others, will allow us to transition to a lighter internal fabrication model where our financial performance will be less volatile and not as heavily influenced by our internal manufacturing volumes. We will continue to rationalize our manufacturing footprint in 2022 to align with our investment priorities and corporate strategy. Our goal is to reduce volatility in our gross margins and maximize return on our manufacturing investments with the intention of having our product strategy drive our manufacturing footprint and capital investments.

In order to streamline our operations and achieve efficiencies, we implemented an involuntary severance plan during 2021, under which approximately 960 employees were notified of their employment termination and we incurred severance and related charges of $65.3 million. We continue to evaluate employee positions and locations for potential efficiencies and may incur additional severance and related charges in the future.

5

We are focused on sustainability as we drive a common theme across all markets. In August 2020, onsemi announced its commitment to achieving net zero emissions by 2040. As we initiate steps to achieve our sustainability goals, additional investments may be required in the future in connection with such actions, although the timing and amounts of such investments are uncertain at this time.

Completed and Pending Acquisitions and Divestitures

On October 28, 2021, we completed our acquisition of GT Advanced Technologies Inc. ("GTAT"), a producer of SiC. Pursuant to the terms and subject to the conditions set forth in the Agreement and Plan of Merger, the purchase price for the acquisition was $434.9 million, which included cash consideration of $424.6 million and effective settlement of pre-acquisition balances (non-cash) of approximately $10 million, in exchange for all of the outstanding equity interests of GTAT. We believe the GTAT acquisition will act as a building block to fuel growth and accelerate innovation in disruptive intelligent power technologies and secure supply of SiC to meet rapidly growing customer demand for SiC-based solutions in the sustainable ecosystem.

On October 1, 2021, we divested one of our businesses along with the related intellectual property for aggregate consideration of approximately $13.6 million and recognized a gain on sale of $10.2 million after offsetting the carrying values of the disposed assets and liabilities.

During 2019 and 2020, we entered into an Asset Purchase Agreement (the "APA") and an Asset Purchase Agreement Amendment (the "APA Amendment") to acquire GLOBALFOUNDRIES U.S. Inc.'s ("GFUS") East Fishkill, New York site and fabrication facilities and certain other assets and liabilities on or around December 31, 2022 for an aggregate purchase price of $400.0 million in cash, subject to adjustments as described in the APA and the APA Amendment (the "Total Consideration"). We paid GFUS $70.0 million and $100.0 million during 2019 and 2020, respectively, of the Total Consideration in cash as a non-refundable deposit, which will be applied toward and reduce the Total Consideration.

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.

Impact of the Novel Coronavirus Disease 2019 ("COVID-19") Pandemic on our Business

In response to the impact of the ongoing COVID-19 pandemic on our business and industry, we have proactively implemented preventative protocols, which we continuously assess and update for current local conditions and emerging trends. These are intended to safeguard our employees, contractors, customers, suppliers and communities and to ensure business continuity in case of further government restrictions or if severe outbreaks impact operations at certain of our facilities. While substantially all of our global manufacturing sites are currently operational, our facilities could be required to temporarily curtail production levels or temporarily cease operations based on government mandates in response to further outbreaks or new variants of COVID-19. We are still unable to predict the ultimate extent to which the COVID-19 pandemic will impact our operations.

Revenue-Generating Activities

onsemi generates revenue from the sale of semiconductor products to distributors and direct customers. We also generate revenue, to a much lesser extent, from product development agreements and manufacturing services provided to customers. We believe that our ability to offer a broad range of products, combined with our global manufacturing and logistics network, provides our customers with single source purchasing on a cost-effective and timely basis.

As many of our products are sold into different end-markets, the total revenue reported under PSG, ASG and ISG 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. From time to time, we reassess the alignment of our product families and devices to our operating segments and may move product families or individual devices from one operating segment to another.

Products and Technology

The following provides certain information regarding the products and technologies for each of our operating segments. See Note 3: ''Revenue and Segment Information'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for other information regarding our segments, their revenue and property, plant and equipment and the gross profit derived from each segment.

PSG

PSG offers a wide array of analog, discrete, module and integrated semiconductor products that perform multiple application functions, including power switching, power conversion, signal conditioning, circuit protection, signal amplification and voltage regulation functions. The trends driving growth within our end-user markets are primarily higher power efficiency and power density in power applications, the demand for greater functionality, and faster data transmission rates in all communications. The advancement of existing volt electrical infrastructure, electrification of power train in the form of EV/HEV, higher trench density enabling lower losses in power efficient packages and lower capacitance and integrated signal conditioning products to support faster data transmission rates significantly increase the use of high power semiconductor solutions. The recent increase in the use of WBG MOSFETs and diodes, including SiC and IGBT, is further expanding the use of semiconductor products.

ASG

ASG designs and develops analog, mixed-signal, advanced logic, ASSPs and ASICs, RF and integrated power solutions for a broad base of end-users in different end-markets. Our product solutions enable industry leading active mode and standby mode efficiency now demanded by regulatory agencies around the world. Additionally, ASG offers trusted foundry and design services for our government customers which leverages the Company’s broad range of manufacturing, IC design, packaging, and silicon technology offerings to provide turn-key solutions for our customers.

ISG

ISG designs and develops CMOS image sensors, image signal processors, single photon detectors, including SiPM and SPAD arrays, as well as actuator drivers for autofocus and image stabilization for a broad base of end-users in the different end-markets. Our broad range of product offerings delivers excellent pixel performance, sensor functionality and camera systems capabilities in which high quality visual imagery is becoming increasingly important to our customers and their end-users, particularly in automotive and factory automation and in applications powered by AI.

Customers

We sell our products to distributors and direct customers for ultimate use in a variety of end-products in different end-markets. In general, we have maintained long-term relationships with our key customers and our sales agreements are renewable periodically and contain certain terms and conditions with respect to payment, delivery, warranty and supply. During 2021, we entered into a number of long-term supply arrangements with certain strategic end-customers, which generally include minimum purchase commitments. Pricing terms on product development agreements are negotiated at the beginning of a project. Almost all of our contracts have default provisions, and certain of our contracts in the public sector are terminable at

7

any time for convenience of the contracting agency.

We generally warrant that products sold to our customers will, at the time of shipment, be free from defects in workmanship and materials and conform to our approved specifications. Our 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. Unless otherwise agreed in writing with our customers, they may cancel orders 120 days prior to shipment for standard products without penalty and, for custom products, prior to shipment, provided they pay onsemi's actual costs incurred as of the date we receive the cancellation notice. The loss of one of our large customers would have a material adverse effect on the operations of the respective segment, and may have a material adverse effect on our consolidated results of operations.

Distributors

Sales to distributors accounted for approximately 64% of our revenue in 2021, 60% of our revenue in 2020 and 57% of our revenue in 2019. We had one distributor whose revenue accounted for approximately 13% of the total revenue for the year ended December 31, 2021. Our distributors resell to mid-sized and smaller OEMs and other companies. Sales to distributors are typically made pursuant to agreements that provide return rights and stock rotation provisions permitting limited levels of product returns.

Direct Customers

Sales to direct customers, which include manufacturers who provide contract manufacturing services for OEMs, accounted for approximately 36% of our revenue in 2021, 40% of our revenue in 2020 and 43% of our revenue in 2019. Large multi-nationals and selected regional OEMs, which are significant in specific markets, form our core direct customers. Generally, these customers do not have the right to return our products following a sale other than pursuant to our warranty.

For additional information regarding agreements with our customers, see "Markets," "Resources" and "Risk Factors - Trends, Risks and Uncertainties Related to Our Business" included elsewhere in this Form 10-K and Note 2: "Significant Accounting Policies - Revenue Recognition" in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K.

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 with which 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 our core competencies of leading edge fabrication technologies, micro packaging expertise, breadth of product line and IP portfolio, high quality cost effective manufacturing and supply chain management which ensures supply to our customers. Our commitment to continual innovation allows us to provide an ever broader range of semiconductor solutions to our customers who differentiate in power density and power efficiency, the key performance characteristics driving our markets.

The principal methods of competition in our discrete, module and integrated semiconductor products are through new products and package innovations enabling enhanced performance over existing products. Of particular importance are our power MOSFETs, IGBTs, WBG MOSFETs and diodes, including SiC rectifiers and power module portfolio for power conversion applications, and ESD portfolio for hi-speed serial interface protection products, where we believe we have significant performance advantages over our competition. PSG's competitors include: Broadcom Limited ("Broadcom"), Diodes Incorporated, Infineon Technologies AG ("Infineon"), Wolfspeed, Nexperia BV, Rohm Semiconductor USA LLC ("Rohm"), Semtech Corporation, STMicroelectronics N.V. ("STMicroelectronics"), Texas Instruments Incorporated ("TI"), Toshiba Corporation and Vishay Intertechnology, Inc.

ASG

ASG principally competes on design experience, manufacturing capability, depth and quality of IP, ability to service customer needs from the design phase to the shipping of a completed product, length of design cycle, longevity of technology support and experience of sales and technical support personnel. Our competitive position with respect to the above basis is enhanced by long-standing relationships with leading direct customers.

Our ability to compete successfully depends on internal and external variables. These variables include, but are not limited to, the timeliness with which we can develop new products and technologies, product performance and quality, manufacturing

9

yields and availability of supply, customer service, pricing, industry trends and general economic trends. Competitors for certain of ASG's products and solutions include: Infineon, NXP Semiconductors N.V. ("NXP"), STMicroelectronics and TI.

ISG

ISG differentiates itself from the competition through deep technical knowledge and close customer relationships to drive leading edge sensing performance for both human and machine vision applications. ISG has significant imaging experience and was one of the earliest to commercialize CMOS active pixel sensors and introduce CMOS technology in many of our markets. ISG has leveraged this expertise into market leading positions in automotive and industrial applications, which allows us to offer technical and end-user applications knowledge to help customers develop innovative sensing solutions across a broad range of end-user needs.

Competitors for certain of ISG's products and solutions include: Sony Semiconductor Manufacturing Corporation, Samsung Electronics Co., Ltd., Omnivision, STMicroelectronics, Rohm, Renesas Electronics Corporation, and Broadcom.

Sales, Marketing and Distribution

We have global distribution centers in China, the Philippines and Singapore. Global and regional distribution channels further support our customers' needs for quick response and service. We offer efficient, cost-effective global applications support from our technical information centers and solution engineering centers, allowing for applications that are developed in one region of the world to be instantaneously available throughout all other regions.

Backlog

Our sales are made primarily pursuant to orders that are booked as far as 52 weeks in advance of delivery. Generally, prices and quantities are fixed at the time of booking. Backlog as of a given date consists of existing orders and forecasted demand from our customers, in each case scheduled to be shipped in the current or future period. Backlog is influenced by several factors, including market demand, pricing and customer order patterns in reaction to product lead times. During 2021, our backlog for shipments requested for a given quarter exceeded actual revenue during such quarter.

In the semiconductor industry, backlog quantities and shipment schedules under outstanding purchase orders are frequently revised to reflect changes in customer needs. Historically, a significant portion of our backlog was cancellable, however, under our current agreements, including orders subject to minimum purchase commitments under our longer-term supply arrangements, are not subject to cancellation. See "Risk Factors—Trends, Risks and Uncertainties Related to Our Business" located elsewhere in this Form 10-K for additional information regarding the inventory practices within the semiconductor industry.

Resources

Raw Materials

Our manufacturing processes use many raw materials, including silicon wafers, SiC wafers, laminate substrates, gold, copper, lead frames, mold compound, ceramic packages and various chemicals and gases as well as other production supplies used in our manufacturing processes. We obtain our raw materials and supplies from a large number of sources, generally on a just-in-time basis. From time to time, suppliers may extend lead times, limit supplies or increase prices due to capacity constraints or other factors. Although we continue to experience some supply constraints due to the current conditions, we could face further shortages in various essential materials as experienced during the COVID-19 pandemic and increased demand in the industry or other factors.

See Note 5: ''Acquisitions and Divestitures'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K regarding the pending acquisition of a manufacturing facility in 2022.

We operate all of our existing manufacturing facilities directly, 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 in Leshan, Leshan Radio Company Ltd. ("Leshan Radio"), is formerly a 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 2021, 2020 and 2019 and are currently committed to purchase approximately 80% of Leshan's expected production capacity in 2022.

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 37% of our total manufacturing input costs in 2021, 33% in 2020 and 31% in 2019.

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 or were licensed or sublicensed to a significant amount of IP, including patents and patent applications, in connection with our acquisitions, and we have numerous U.S. and foreign patents issued, allowed and pending. As of December 31, 2021, we held patents with expiration dates ranging from 2022 to 2040, and none of the patents that expire in the next three years materially affect our business. 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.

Seasonality

We believe our business today is driven more by content gains within applications and secular growth drivers and not solely by macroeconomic and industry cyclicality, as was the case historically. Our 2021 results were positively influenced by macroeconomic factors including a better-than-expected economic recovery from the COVID-19 pandemic along with our efforts focused on price increases, better utilization, product diversification and content gains. We could again experience period-to-period fluctuations in operating results due to general industry or macroeconomic conditions. 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 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, 2021 were not material, and we do not 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 the capital expenditures or earnings or our competitive position. It is possible, however, that future developments, including

12

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, U.S. or China 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, 2021 were not material, and we do not expect the cost of complying with existing trade laws and regulations to have a material adverse effect on the capital expenditures or earnings or our competitive position. 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 social and governance priorities will help enhance long-term value for our stockholders.

In 2021, onsemi affirmed its climate change policy, highlighting the focus areas for its climate change-related actions. onsemi is committed to protect and respect its environment and energy resources for future generations throughout its manufacturing operations including wafer fabrication, assembly, test, and support operations. In that regard, onsemi has committed to achieving net zero emissions by 2040.

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 verify compliance to the Responsible Business Alliance (“RBA”) Code of Conduct including the elimination of forced labor, slavery and human trafficking and conflict minerals as per our involvement with the Responsible Minerals Initiative.

Our Board of Directors and management regularly evaluate our corporate responsibility policies, including our Code of Business Conduct and other corporate social responsibility policies and programs, to 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, manufacture and support of new and existing products and services. We are a member of the RBA, the principles of which 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 to our employees that emphasizes learning and professional development and respect for individuals and ethical conduct.

Headcount

As of December 31, 2021, we had approximately 30,000 regular full-time employees and approximately 3,300 part-time and temporary employees in facilities located in 35 countries. Approximately 12% of our regular full-time employees are located in the United States and Canada, 13% in Europe and Middle Eastern countries and 75% in Asia Pacific and Japan, with approximately 71% engaged in manufacturing, 2% directly in research and development, 3% in customer service or other

13

aspects of sales and marketing, and 24% in other roles. Approximately 107 of our domestic employees (or approximately 3% of our U.S. based employees) are covered by a collective bargaining agreement. 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.

Diversity, Equity and Inclusion

We are consciously expanding the diversity of our workforce, creating growth and development opportunities for our employees, embracing different perspectives and fostering an inclusive work environment. We have organization level and overall Company metrics to monitor for diverse director-level and above employees, diverse new hires and diverse promotions. Our Human Resources organization and the Human Capital and Compensation Committee of the board of directors of the Company (the "Board of Directors"), through its charter, provides oversight of our policies, programs and initiatives focusing on workflow equity and workplace inclusion.

Compensation, Benefits, Health, Safety and Wellness

Our compensation philosophy is focused on delivering total rewards based on corporate affordability in a way that enables attraction, retention, and recognition of performance delivered in an equitable manner. 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. Our primary focus during the COVID-19 pandemic has been protecting the health and safety of our employees and the communities in which we operate. 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; backup child and adult care; 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 improving 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 the Company as a whole. The average tenure of our employees is approximately seven years and approximately one-fifth of our employees have been employed by us for more than 10 years. We believe our compensation philosophy along with the career growth and development opportunities promotes longer employee tenure and reduces voluntary turnover.

Item 1A.    Risk Factors

Forward-Looking Statements

This Annual Report on Form 10-K includes "forward-looking statements," as that term is defined in Section 27A of the Securities Act and Section 21E of the Exchange Act. All statements, other than statements of historical facts, included or incorporated in this Form 10-K could be deemed forward-looking statements, particularly statements about our plans, strategies and prospects under the headings "Management’s Discussion and Analysis of Financial Condition and Results of Operations" and "Business." Forward-looking statements are often characterized by the use of words such as "believes," "estimates," "expects," "projects," "may," "will," "intends," "plans," "anticipates," "should" or similar expressions, or by discussions of strategy, plans or intentions. All forward-looking statements in this Form 10-K are made based on our current expectations, forecasts, estimates and assumptions, and involve risks, uncertainties and other factors that could cause results or events to differ materially from those expressed in the forward-looking statements. Readers are cautioned not to place undue reliance on forward-looking statements. We assume no obligation to update such information, except as may be required by law.

You should carefully consider the trends, risks and uncertainties described below and other information in this Form 10-K and subsequent reports filed with or furnished to the SEC before making any investment decision with respect to our securities. If any of the following trends, risks or uncertainties actually occurs or continues, our business, financial condition or operating results could be materially and adversely affected, the trading prices of our securities could decline, and you could lose all or part of your investment. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by this cautionary statement.

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 processes among our various internal facilities, and any disruption in these processes could have a material adverse effect on our ability to produce many of our products at all or at competitive prices, which could in turn materially adversely affect 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 contractors. 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 increases 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 this manufacturing efficiency, increase manufacturing efficiency to the same extent as our competitors, or be successful in our manufacturing

16

rationalization plans. 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.

The effects of the COVID-19 pandemic have had, and could continue to have, an adverse impact on our business, results of operations and financial condition.

Our business has been, and is expected to continue to be, adversely impacted by the effects of the COVID-19 pandemic. In addition to global macroeconomic effects, the COVID-19 pandemic and related adverse public health developments have been causing, and are expected to continue to cause, disruption to our domestic and international operations and sales activities. In addition, we and our suppliers, third-party distributors, sub-contractors and customers have been, and are expected to continue to be, disrupted by 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 or other travel or health-related restrictions. Depending on the magnitude of such effects on our manufacturing activities or the operations of our suppliers, third-party distributors or sub-contractors, 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, any economic downturn or recession brought on by the COVID-19 pandemic or other disease outbreaks could adversely affect demand for our products and impact our results of operations and financial condition. These effects, alone or taken together, could have a material adverse effect on our business, results of operations, legal exposure, or financial condition. The extent of the COVID-19 pandemic’s effect on our operational and financial performance will depend on future developments, including the duration, spread and intensity of the pandemic, including resurgences in certain geographic areas as a result of new strains and variants, such as Delta and Omicron, the efficacy of vaccines, the speed of vaccine rollouts and the effect of vaccine mandates, if any, on our employees, all of which are uncertain and difficult to predict. While we are not able at this time to estimate the long-term effect of these factors on our business, the adverse impact on our business, results of operations, financial condition and cash flows has been, and could continue to be, material.

We may be unable to implement certain business strategies, which may include exiting certain facilities, product lines or businesses, or restructuring our operations, and any issue with the pursuit of such business strategy developments 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, following the announcement of our commitment to achieving carbon neutral 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. In addition, 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 as required to remain competitive in our business, 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

17

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 that 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.

The semiconductor industry is characterized by rapidly changing technologies, innovation, short product life cycles, evolving regulatory and industry standards and certifications, changing customer needs and frequent new product introductions. Products are frequently 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 rapid 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.

The semiconductor industry is highly competitive, and our ability to compete successfully 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. 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, 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. 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 would have a material adverse effect on our business.

Because a significant portion of our revenue is derived from customers in the automotive industry, a downturn or lower sales to customers in the industry could materially adversely affect our business and results of operations.

A significant portion of our sales are to customers within the automotive industry. Sales into this industry represented approximately 34% of our revenue for the year ended December 31, 2021. The automotive industry is cyclical, and, as a result, our customers in the industry are sensitive to changes in general economic conditions, disruptive innovation and end-market preferences, which can adversely affect sales of our products and, correspondingly, our results of operations. Additionally, the quantity and price of our products sold to customers in the industry could decline despite continued growth in its respective end markets. Lower sales to customers in the automotive industry 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 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

18

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. 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 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 tariffs and trade restrictions as a result of international trade disputes or changes in trade policies may adversely affect our sales and profitability. For example, additional tariffs and the related geopolitical uncertainty between the United States and China and other countries may cause decreased end market demand for our products from distributors and other customers, which could have a material adverse effect on our business and 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 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 U.S. 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.

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 U.S. and internationally. In the semiconductor industry, the competition for qualified personnel, particularly experienced design engineers and other technical employees is intense. During such periods, competitors may try to recruit our most valuable technical 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. While we devote a great deal of our attention to designing competitive compensation programs aimed at attracting and retaining personnel, 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

19

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.

Since a defect or failure in our product 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 U.S., many of our liabilities, including our outstanding indebtedness, and certain other cash payments, such as share repurchases, are payable in the U.S. 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 U.S. 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 U.S., 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 U.S. 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 processes; or obtain licenses, which may not be available on reasonable terms, to the 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 U.S. 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:

20

•any of the substantial number of U.S. 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 U.S. or foreign countries.

When we seek to enforce our rights, we are often subject to claims that the IP right is invalid, is otherwise not enforceable or is licensed to the party against whom we are asserting a claim. In addition, 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

We may be subject to disruptions or breaches of our secured network that 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 critical to our operations and business strategy. We may be subject to disruptions or breaches of our secured network caused by computer viruses, illegal hacking, criminal fraud or impersonation, acts of vandalism or terrorism or employee error. Our cyber security measures and/or those of our third-party service providers and/or customers may not detect or prevent such security breaches. The costs to us to reduce the risk of or alleviate cyber security breaches and vulnerabilities could be significant, and our efforts to address these problems may not be successful and could result in interruptions and delays that may materially impede our sales, manufacturing, distribution or other critical functions. Any such compromise of our information security could result in the misappropriation or unauthorized publication of our confidential business or proprietary information or that of other parties with which we do business, an interruption in our operations, the unauthorized transfer of cash or other of our assets, the unauthorized release of customer or employee data or a violation of privacy or other laws. In addition, computer programmers and hackers also may be able to develop and deploy viruses, worms and other malicious software programs that attack our products, or that otherwise exploit any security vulnerabilities, and any such attack, if successful, could expose us to liability to customer claims. Any of the foregoing could irreparably damage our reputation and business, which could have a material adverse effect on our results of operations.

The Company is 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 U.S. 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 the Company or company officials, including substantial monetary fines, and could damage our reputation, inhibit sales and adversely affect our business.

Trends, Risks and Uncertainties Related to Regulation

21

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

The semiconductor industry has been subject to increasing environmental regulations, particularly those environmental regulations 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. 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 U.S. and international environmental or health and safety laws or regulations, including, but not limited to, future laws or regulations imposed in response to climate change concerns;

•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.

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.

We are subject to anti-corruption laws in the jurisdictions in which we operate, including the FCPA. Our failure to comply with these 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 U.S. or foreign authorities could harm our reputation and have an adverse impact on our business, financial condition and results of operations.

We could be subject to changes in tax legislation or have exposure to additional tax liabilities, which 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 jurisdictions in which we operate. Changes to, or interpretations of, tax legislation or regulations could significantly increase our effective tax rate 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 and ultimately reduce our cash flow from operating activities.

Tax rules may change in a manner that adversely affects our future reported results of operations or the way we conduct our business. In response to the 2017 Tax Cuts and Jobs Act and to better align our profits with our activities, we implemented certain restructuring during the year ended December 31, 2020. After our restructuring, 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%. Further, if U.S. rates increase and/or the FDII deduction is eliminated or reduced, both of which have been proposed by the current U.S. presidential administration and Congress, our provision for income taxes, results of operations and cash flows would be adversely (potentially materially)

22

affected. Also, if our customers move manufacturing operations to the United States, our FDII deduction may be reduced.

Further changes in tax laws of foreign jurisdictions could arise as a result of the base erosion and profit shifting project that was undertaken by the Organisation for Economic Co-operation and Development (“OECD”). The OECD, which represents a coalition of member countries, recommended changes to numerous long-standing tax principles related to transfer pricing and continues to develop new proposals including allocating greater taxing rights to countries where customers are located and establishing a minimum tax on global income. These changes, as adopted by countries, may increase tax uncertainty and may adversely affect our provision for income taxes, results of operations and financial condition.

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.

More investors are also requiring companies to disclose corporate social and environmental policies, practices and metrics. In addition, various jurisdictions 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 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. 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, and may take legal action against us, which could harm our reputation, revenue and results of 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, 2021, we had $3,258.3 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, 2021, we had approximately $1.97 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:

•our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, general corporate purposes or other purposes may be impaired;

•the timing, amount and execution of our capital allocation policy, including our Share Repurchase Program (as defined below), could be affected by the degree to which we are leveraged;

•a significant portion of our cash flow from operating activities must be dedicated to service our debt, which reduces the funds available to us for our operations and may limit our ability to engage in activities that may be in our long-term best interests;

•some of our debt are and will continue to be at variable rates of interest, which may result in higher interest expense in the event of increases in market interest rates;

•our debt agreements may contain, and any agreements to refinance our debt could continue to contain, financial and restrictive covenants, and our failure to comply with them may result in an event of default which if not cured or waived, could have a material adverse effect on us;

•our level of indebtedness will increase our vulnerability to, and reduce our flexibility to respond to, general economic downturns and adverse industry and business conditions;

•as our long-term debt ages, we must repay, and may need to renegotiate, such debt or seek additional financing;

•our existing debt requires substantially all of our assets to be collateralized and to the extent any future debt we incur requires collateral to secure such indebtedness, our assets could be at risk and our flexibility related to such assets could be limited;

•our debt service obligations could limit our flexibility in planning for, or reacting to, changes in our business and the semiconductor industry;

23

•our ability to deduct interest expense that we may incur may be limited or deferred under U.S. and/or local tax rules, including Section 163(j) of the Code and the Treasury Regulations promulgated thereunder; and

•our level of indebtedness may place us at a competitive disadvantage relative to less leveraged competitors.

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 Amended 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 Amended Credit Agreement are collateralized by a lien on substantially all of the personal property and material real property assets of the Company’s domestic subsidiaries. As a result, if we are unable to satisfy our obligations under the Amended 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, subject to customary exceptions, the Amended Credit Agreement requires mandatory prepayment under certain circumstances, which may result in prepaying outstanding amounts under the Revolving Credit Facility and the Term Loan "B" Facility rather than using funds for other business purposes. Our financing 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 Amended 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 Amended 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, including issuing guarantees; incur liens; make certain investments; settle a conversion of our 1.625% Notes in whole or in part with cash; redeem, or otherwise perform our obligations under the terms of, our 3.875% Notes; sell or otherwise dispose of assets; make acquisitions; 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. These restrictions may limit our ability to engage in activities that could otherwise benefit us. To the extent that we are unable to engage in activities that support the growth, profitability and competitiveness of our business, our results of operations 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 Amended Credit Agreement, could also limit our ability to make

24

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 current stockholders.

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 Amended Credit Agreement, are at variable rates of interest and as a result expose us to interest rate risk. If interest rates were to increase, 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. While we have entered into swap agreements to reduce interest rate volatility for a portion of our Term Loan "B" Facility through 2024, 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.

Our Amended Credit Agreement and our interest rate swap agreements have an interest rate tied to LIBO Rate. While certain of these agreements, such as the Amended Credit Agreement, provide procedures for determining an alternative base rate in the event that LIBO Rate is discontinued, not all do so. Effective as of December 31, 2021, the United Kingdom Financial Conduct Authority ("FCA"), which regulates the LIBO Rate, no longer publishes LIBO Rate quotations, including one-week and two-month U.S. dollar LIBOR settings. The publication of overnight and one-, three-, six- and 12-month U.S. dollar LIBOR settings will be extended through June 30, 2023. Further, on October 21, 2021, five U.S. federal financial institution regulatory agencies, in conjunction with U.S. state bank and state credit union regulators, issued a joint statement to emphasize the expectation that supervised institutions with LIBO Rate exposure continue to progress toward an orderly transition away from LIBO Rate in advance of the 2023 deadline and providing considerations with respect to alternative base rates and appropriate fallback language, noting that failure to adequately prepare for the LIBO Rate’s discontinuance could undermine financial stability and institutions’ safety and soundness and create litigation, operational, and consumer protection risks. Regardless, there can be no assurances as to what alternative base rates may be and whether such base rates will be more or less favorable than LIBO Rate and any other unforeseen impacts of the discontinuation of LIBO Rate. The Company intends to monitor the developments with respect to the phasing out of LIBO Rate and work with its lenders to ensure the transition away from LIBO Rate will have minimal impact on its financial condition, but can provide no assurances that the impact of the discontinuation of LIBO Rate would not have a material adverse effect on its results of operations.

25

The timing of the cash payments to service the 0% Notes, the 1.625% 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, 2021, we had outstanding approximately $155.1 million aggregate principal amount of our 1.625% Notes, $700.0 million aggregate principal amount of our 3.875% Notes and $805.0 million of aggregate principal of our 0% 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 1.625% Notes or the 0% 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.

Further, if we are unable to make cash payments upon conversion of the 1.625% Notes or the 0% Notes, we would be required to issue significant amounts of our common stock, which would dilute existing stockholders.

In certain circumstances, a takeover of our Company and similar triggering events could also trigger an option of the holders of the 1.625% Notes, the 3.875% Notes and the 0% 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 1.625% Notes, the 3.875% Notes, the 0% Notes and our common stock, which could materially decrease the value of such notes and of our common stock.

The terms of the Amended 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.

The conditional conversion features of the 1.625% Notes and the 0% Notes, if triggered, may adversely affect our financial condition and results of operations and, if we elect to settle any amounts related to conditional conversion features in common stock, any such settlement could materially dilute the ownership interests of existing stockholders.

If specified conditions are met, holders of the 1.625% Notes and the 0% Notes may convert their notes prior to their stated maturity in the event the conditional conversion features are triggered, holders electing to convert their notes could require us to settle a portion or all of our conversion obligations through the payment of cash. Further, we are required to settle conversions of the 0% Notes in cash up to the aggregate principal amount of the notes being converted and may elect to pay or deliver, as the case may be, cash or shares of common stock, or a combination, to settle the remaining amount. Any such cash payments could materially adversely affect our liquidity. Additionally, when the conditional conversion features are triggered at the end of a reporting period, we are required under applicable accounting rules to reclassify the outstanding principal of such notes as a current rather than long-term liability, which would result in a material reduction of our net working capital. A conditional conversion feature under the 1.625% Notes has been triggered as of December 31, 2021 and in certain prior quarters, and we can provide no assurance as to when or whether these conditional conversion features will lapse or be triggered again in the future. Any material decrease in our liquidity or reduction in our net working capital could have a material adverse effect on our financial condition and results of operations. In addition, we may elect to settle the 1.625% Notes solely in common stock to avoid an event of default under our Amended Credit Agreement, and any such issuance of common stock could materially dilute the ownership interests of existing stockholders, including stockholders who previously converted such notes to shares of our common stock. Our 0% Notes require the principal of $805.0 million to be paid in cash, the excess value, if any, can be paid in a combination of cash or shares. To the extent we elect to settle the excess in shares, the ownership interests of existing stockholders could be materially diluted.

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 1.625% Notes and the 0% 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

26

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 1.625% Notes and the 0% 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 $30.70, with respect to the 1.625% Notes, and $74.34, with respect to the 0% Notes.

In connection with establishing their initial hedge of the convertible note hedges and warrant transactions for the 1.625% Notes and the 0% 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 1.625% Notes and/or the 0% Notes and/or cash payments we are required to make in excess of the principal amount of converted 1.625% Notes and/or the 0% 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 our Company, 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 any 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 our Company that would have been beneficial to our stockholders could materially decrease the value of our common stock.

General Risk Factors

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

27

We have made, and may continue to make, strategic acquisitions and alliances 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.

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 financial crises, subsequent recoveries and persistent economic uncertainty. We believe our business today is driven more by secular growth drivers and not solely by macroeconomic and industry cyclicality, as was the case historically, yet we could experience period-to-period fluctuations in operating results due to general industry or economic conditions 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.

In addition to general economic conditions, impacts of other macroeconomic events, such as the COVID-19 pandemic, climate change and other natural disasters, 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.

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

Various jurisdictions 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, and 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.

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. Actual results could differ materially because of the factors discussed in "Risk Factors" included elsewhere in this Form 10-K.

Executive Overview

This executive overview presents summarized information regarding our business and operating trends only. For further information relating to the information summarized herein, see "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, 2021 was $6,739.8 million, an increase of 28.3% from $5,255.0 million for the year ended December 31, 2020. The increase was attributable to the improving economic conditions and an exceptionally strong market for semiconductor products resulting in a significant increase in demand across PSG, ASG and ISG. During 2021, we reported net income attributable to onsemi of $1,009.6 million compared to $234.2 million in 2020. Our operating income totaled $1,287.6 million during 2021 compared to $348.7 million during 2020. The increase in operating income and net income attributable to onsemi was due to significantly better gross margins from higher sales volume, favorable mix, increase in average selling prices, better utilization in factories and savings from restructuring activities. Our gross margin increased by approximately 760 basis points to 40.3% in 2021 from 32.7% in 2020. See discussion under "Results of Operations" for additional discussion on the reasons for the fluctuations year over year.

Business and Macroeconomic Environment

The COVID-19 pandemic has had, and continues to have, a significant impact around the world, prompting governments and businesses to take unprecedented measures including restrictions on travel, business operations and temporary closures of facilities. However, during 2021, economic conditions began to improve and business conditions became stronger during the second half of the year. During 2021, we achieved revenue growth in our focused end-markets of automotive, industrial and communications infrastructure as well as expand our gross margin and operating margin as a result of cost-saving initiatives, product rationalization, favorable mix and price increases, among other actions. While the semiconductor industry conditions have resulted in increased costs throughout our supply chain, we have been able to pass a majority of such increases to our customers, which also contributed to higher revenue for 2021. We expect to continue to pursue 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 increased costs. We have taken, and continue to take, significant cost containment efforts, including, but

31

not limited to, workforce reductions and reducing discretionary spending.

The ongoing impact of the COVID-19 pandemic on the Company’s operational and financial performance is uncertain and will depend on many factors outside the Company’s control, including the timing, extent, trajectory and duration of the pandemic, the emergence of new variants, the development, availability, distribution and effectiveness of vaccines and treatments, the imposition of protective public safety measures, and the impact of the pandemic on the global economy and demand for products. While all our global manufacturing sites are currently operational, our facilities could be required to temporarily curtail production levels or temporarily cease operations based on government mandates due to the COVID-19 pandemic. There can be no assurances that we will adequately forecast the magnitude or duration of the adverse economic conditions on our business or that we will effectively align our cost structure, capital investments and other expenditures with our revenue, spending and capacity levels in the future.

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.

_______________________

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

Revenue from PSG

Revenue from PSG increased by $833.0 million, or approximately 32%, during 2021 compared to 2020. The revenue from our

33

Advanced Power Division and our Integrated Circuits, Protection and Signal Division increased by $521.7 million and $317.6 million, respectively. These increases primarily were driven by better economic conditions resulting in increased demand for our products along with a favorable mix in the products sold and an increase in average selling prices. Although we experienced supply chain constraints during 2021, they were offset by increased demand for our products, however in 2020, we experienced decreased demand, delays in fulfilling certain customer orders and certain of our factories operating at significantly reduced capacity levels as a result of the COVID-19 pandemic.

Revenue from ASG

Revenue from ASG increased by $489.5 million, or approximately 25.6%, during 2021 compared to 2020. The revenue from our Mobile, Computing and Cloud Division, our Automotive Division and our Industrial Solutions Division, increased by $230.3 million, $155.0 million and $110.2 million, respectively. The increases primarily were due to improved economic conditions resulting in increased demand for our products in other end-markets along with a favorable mix in the products sold and an increase in average selling prices. Although we experienced supply chain constraints during 2021, they were offset by increased demand for our products, however in 2020, we experienced decreased demand, delays in fulfilling certain customer orders and certain of our factories operating at significantly reduced capacity levels as a result of the COVID-19 pandemic.

Revenue from ISG

Revenue from ISG increased by $162.3 million, or approximately 22%, during 2021 compared to 2020. The revenue from our Automotive Sensing Division and our Industrial and Consumer Solutions Division increased by $152.5 million and $70.7 million, respectively, and was partially offset by a decrease of $61.0 million from the exited CCD business. The increase in revenue was due to the improvement in economic conditions, specifically with automotive component manufacturers and the automotive industry overall, resulting in increased demand for these products along with a favorable mix in the products sold and an increase in average selling prices.

Revenue by Geographic Location

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

	2021		As a % of Revenue (1)		2020		As a % of Revenue (1)
Singapore	$	2,097.8	31.1	%	$	1,799.5	34.2	%
Hong Kong	1,828.6		27.1	%	1,311.6		25.0	%

Gross Profit and Gross Margin (exclusive of amortization of acquisition-related intangible assets)

Our gross profit by operating and reportable segment was as follows (dollars in millions):

	2021		As a % of Segment  Revenue (1)		2020 (2)		As a % of Segment  Revenue (1)
PSG	$	1,318.3	38.3	%	$	764.1	29.3	%

ISG	340.4		37.8	%	237.3		32.1	%
Total gross profit	$	2,714.3	40.3	%	$	1,715.8	32.7	%

_______________________

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

(2)Beginning in 2021, unallocated manufacturing costs were included as part of segment operating results to determine

34

segment gross profit. As a result, the prior-period amounts have been reclassified to conform to current-period presentation.

Our gross profit increased by $998.5 million, or approximately 58%, from $1,715.8 million during 2020 to $2,714.3 million during 2021. Gross margin increased to 40.3% during 2021 compared to 32.7% during 2020.

The increases in gross profit and gross margin were due to increases in sales volume, increased utilization and a better mix in the portfolio of the products sold combined with an increase in average selling prices for many of our products. The favorable economic environment and significant improvement in demand in all end-markets and specifically from automotive and industrial end-markets contributed to increased demand and better pricing for our products. We were also able to pass a majority of the increased cost from our suppliers to our customers.

Operating Expenses

Research and Development

Research and development expenses were $655.0 million and $642.9 million, or approximately 10% and 12% of revenue for 2021 and 2020, respectively, representing an increase of $12.1 million, or approximately 2% year-over-year. The increase in variable compensation was partially offset by a decrease in payroll expenses due to restructuring activities, and costs associated with third-party consultants.

Selling and Marketing

Selling and marketing expenses were $293.6 million and $278.7 million, or approximately 4% and 5% of revenue for 2021 and 2020, respectively, representing an increase of $14.9 million, or approximately 5% year-over-year. The increase was primarily due to an increase in variable compensation.

General and Administrative

General and administrative expenses were $304.8 million and $258.7 million, or approximately 5% and 5% of revenue for 2021 and 2020, respectively, representing an increase of $46.1 million, or approximately 18% year-over-year. The increase was primarily due to an increase in variable compensation and stock compensation.

Amortization of Acquisition—Related Intangible Assets

Amortization of acquisition-related intangible assets was $99.0 million and $120.3 million for 2021 and 2020, respectively. The decrease of $21.3 million, or approximately 17.7%, was primarily due to the full amortization of certain of our technology-related intangible assets during 2020.

Restructuring, Asset Impairments and Other Charges, net

Restructuring, asset impairments and other charges, net was $71.4 million and $65.2 million for 2021 and 2020, respectively. Amounts incurred during 2021 primarily related to the involuntary severance plan. Amounts incurred during 2020 related to the voluntary and involuntary severance plans and certain general workforce reductions. Included in 2020 was also asset impairment charges of $17.5 million.

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 $38.0 million, or approximately 22.6%, to $130.4 million during 2021 compared to $168.4 million in 2020, primarily due to the decrease in our long-term debt and a decrease in interest rates on our variable rate debt. Our average gross amount of long-term debt balance (including current maturities) during 2021 and 2020 was $3,423.9 million and $3,669.4 million, respectively. Our weighted average interest rate on our gross amount of long-term debt (including current maturities) was 3.8% and 4.6% per annum in 2021 and 2020, respectively.

See "Liquidity and Capital Resources—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.

Gain on Divestiture of Business

Gain on divestiture of business was $10.2 million in 2021, compared to zero in 2020, due to the divestiture of a business entity engaged in research and development.

Loss on Debt Refinancing and Prepayment

We recorded loss on debt refinancing and prepayment of $29.0 million during 2021 related to the partial repurchase or exchange of certain of the outstanding 1.625% Notes. See "Liquidity and Capital Resources—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. No such expenses were incurred during 2020.

Other Income (Expense)

Other income (expense) was an expense of $8.6 million in 2020 compared to an income of $18.0 million in 2021, reflecting a change of approximately 309.3%. During 2021, we recognized actuarial gains on our pension obligations of $21.4 million which was partially offset by miscellaneous adjustments of $4.6 million, compared to an actuarial loss of $4.0 million during 2020.

Income Tax Provision

We recorded an income tax provision of $146.6 million and a benefit of $59.8 million in 2021 and 2020, respectively.

The income tax provision for the year ended December 31, 2021 consisted primarily of $179.4 million for income and withholding taxes of certain of our foreign and domestic operations, $3.6 million related to a discrete foreign tax rate change, $2.9 million related to return to provision adjustments and $3.4 million related to additional valuation allowance, partially offset by discrete benefits of $24.3 million relating to the release of uncertain tax positions in foreign jurisdictions for favorable audit results and lapse of statue, $6.9 million relating to net equity award windfalls and $11.5 million primarily relating to an increase in deferred tax assets expected to be realized in the foreseeable future due to the liquidation of a foreign subsidiary.

The income tax benefit for the year ended December 31, 2020 consisted of discrete benefits of $63.0 million primarily due to the recognition of certain deferred tax assets, net of deferred tax liabilities, related to the domestication of certain foreign subsidiaries and a benefit of $49.4 million related to the release of valuation allowance against certain state deferred tax assets. These benefits were partially offset by a provision of $43.9 million for income and withholding taxes of certain of our foreign and domestic operations, a $2.3 million discrete provision relating to prior year uncertain tax positions, a discrete provision of $5.5 million relating to additional foreign valuation allowance, and $0.9 million of other discrete items.

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

This section includes a discussion and analysis of our cash requirements, contingencies, sources and uses of cash, operations, working capital and long-term assets and liabilities.

Contingencies

We are a party to a variety of agreements entered into in the ordinary course of business pursuant to which we may be obligated to indemnify 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 us require us to indemnify the other party against losses, including, but not limited to, losses due to IP infringement, environmental contamination and other property damage, personal injury, our failure to comply with applicable laws, our negligence or willful misconduct or our breach of representations, warranties or covenants related to such matters as title to sold assets.

36

We face 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 economic damage, bodily injury or property damage. In addition, if any of our designed products are alleged to be defective, we may be required to participate in their recall. Depending on the significance of any particular customer and other relevant factors, we may agree to provide more favorable rights to such customer for valid defective product claims. We maintain directors’ and officers’ insurance policies that indemnify our directors and officers against various liabilities, including certain liabilities under the Exchange Act that might be incurred by any director or officer in his or her capacity as such.

While our 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 our obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by us under any of these indemnities have not had a material effect on our business, financial condition, results of operations or cash flows, and we do not believe that any amounts that we may be required to pay under these indemnities in the future will be material to our business, financial condition, results of operations or cash flows.

See Note 13: ''Commitments and Contingencies'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for possible contingencies related to legal matters. See also "Business—Government Regulation" for information on certain environmental matters.

Sources and Uses of Cash

Our balance of cash and cash equivalents was $1,352.6 million as of December 31, 2021. 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) conduct research and development; (iv) incur capital expenditures; and (v) repurchase our common stock. As part of our business strategy, we review acquisition and divestiture opportunities on a regular basis. During 2021, we completed the acquisition of GTAT. See Note 5: ''Acquisitions and Divestitures'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K.

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

•Changes in demand for our products, including as a result of the COVID-19 pandemic, 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

•Our access to bank financing and the debt and equity capital markets that could impair 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.

The following are some of the significant sources and uses of cash during 2021 outside of our operating activities and regular capital expenditures:

•Issuance of $805.0 million aggregate principal amount of 0% Convertible Senior Notes due 2027, the net proceeds of which were used to repurchase $372.4 million in aggregate principal amount of our outstanding 1.625% Notes for a total consideration of $506.5 million in cash and 5.4 million shares of the Company's common stock.

•Payment of $160.3 million for convertible note hedges and receipt of $93.8 million for the sale of warrants, both in relation to the issuance of the 0% Notes.

•Repayment of the outstanding balance of $700.0 million under the Revolving Credit Facility.

•Repurchase of $47.4 million in aggregate principal amount of our outstanding 1.625% Notes for $47.4 million in cash and 1.6 million shares of the Company's common stock.

•Acquisition of GTAT for $424.6 million in cash.

•Net purchases of available-for-sale securities for $44.7 million.

Our ability to service our long-term debt, including our 0% Notes, 3.875% Notes, 1.625% Notes, the Revolving Credit Facility and the Term Loan "B" Facility, to remain in compliance with the various covenants contained in our debt agreements and to fund working capital, 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 and the timing of the full economic recovery from the COVID-19 pandemic, as well as to financial, competitive, legislative, regulatory and other conditions, some of which may be beyond our control.

37

If we fail to generate sufficient cash from operations, we may need to raise additional equity or borrow additional funds to achieve our longer-term objectives. There can be no assurance that such equity or borrowings will be available or, if available, will be at rates or prices acceptable to us. We believe that cash flow from operating activities coupled with existing cash and cash equivalents and existing credit facilities will be adequate to fund our operating, debt repayment and capital needs, as well as enable us to maintain compliance with our various debt agreements, through at least the next 12 months. To the extent that results or events differ from our financial projections or business plans, our liquidity may be adversely impacted.

During the ordinary course of business, we evaluate our cash requirements and, if necessary, adjust our expenditures for inventory, operating expenditures and capital expenditures to reflect the current market conditions and our projected sales and demand. Our capital expenditures are primarily directed towards manufacturing equipment, and can materially influence our available cash for other initiatives. Our capital expenditure levels can materially influence our available cash for other initiatives. For example, during 2021, we paid approximately $444.6 million for capital expenditures, while in 2020 we paid approximately $383.6 million. While our capital expenditures have historically been approximately 6% to 7% of annual revenue, we expect to incur capital expenditures in the range of 11% to 12% of revenue in 2022 to expand our manufacturing capabilities to meet the market demands and further improve our manufacturing cost structure.

As of December 31, 2021, there was $1,598.2 million outstanding under the Term Loan "B" Facility, in addition to $805 million aggregate principal amount of the 0% Notes, $700 million aggregate principal amount of 3.875% Notes and $155.1 million aggregate principal amount of the 1.625% Notes. The aggregate principal amount of outstanding 1.625% Notes, net of unamortized discount and issuance costs, has been reclassified as a current portion of long-term debt. The associated interest expense related to this indebtedness will continue to have a significant impact on our results of operations.

See Note 5: ''Acquisitions and Divestitures'' and Note 9: ''Long-Term Debt'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K for additional information.

Cash Management

Our ability to manage cash is limited, as our primary cash inflows and outflows are dictated by the terms of our sales and supply agreements, contractual obligations, debt instruments and legal and regulatory requirements. While we have some flexibility with respect to the timing of capital equipment purchases, we must invest in capital equipment on a timely basis to allow us to maintain our manufacturing efficiency and support our platforms for new products.

Primary Cash Flow Sources

Our long-term cash generation is dependent on the ability of our operations to generate cash. Our cash flows from operating activities were $1,782.0 million, $884.3 million, and $694.7 million for the years ended December 31, 2021, 2020 and 2019, respectively. Our operating cash flows for the year ended December 31, 2021 increased by $897.7 million, or 101.5%, compared to the year ended December 31, 2020, which was primarily due to better economic conditions resulting in significantly increased demand for our products, increase in average selling prices, better mix in the products sold, cash savings from restructuring activities and better working capital management.

Our ability to maintain positive operating cash flows is dependent on, among other factors, our success in achieving our revenue goals and 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, and each of these components is discussed below.

Working Capital

Working capital, calculated as total current assets less total current liabilities, fluctuates depending on end-market demand and our effective management of certain items such as receivables, inventory and payables. In times of escalating demand, our working capital requirements may be affected as we purchase additional manufacturing materials and increase production. Our working capital may also be affected by restructuring programs, which may require us to use cash for severance payments, asset transfers and contract termination costs. In addition, our working capital may be affected by acquisitions and transactions involving our convertible notes and other debt instruments. Although investments made to fund working capital will reduce our cash balances, these investments are necessary to support business and operating initiatives.

Our working capital, excluding cash and cash equivalents and the current portion of long-term debt, was $1,046.3 million as of December 31, 2021 and has fluctuated between $885.0 million and $1,057.1 million at the end of each of our last eight fiscal quarters. Our working capital, including cash and cash equivalents and the current portion of long-term debt, was $2,238.2

38

million as of December 31, 2021 and has fluctuated between $1,457.6 million and $2,379.8 million at the end of each of our last eight fiscal quarters. The significant fluctuation was due to the withdrawal and repayment on our Revolving Credit Facility during 2020 and 2021 as well as the reclassification of the 1.625% Notes as a current liability. We expect a significant increase in capital expenditures during 2022.

Long-Term Assets and Liabilities

Our long-term assets consist primarily of property, plant and equipment, intangible assets, deferred taxes and goodwill. Our manufacturing rationalization plans have included efforts to utilize our existing manufacturing assets and supply arrangements more efficiently. We believe that near-term access to additional manufacturing capacity, should it be required, could be readily obtained on reasonable terms through manufacturing agreements with third parties. We will continue to look for opportunities to make strategic purchases in the future for additional capacity.

Our long-term liabilities, excluding long-term debt and deferred taxes, consist of liabilities under our foreign defined benefit pension plans, operating lease liabilities and contingent tax reserves. In regard to our foreign defined benefit pension plans, our annual funding of these obligations is equal to the minimum amount legally required in each jurisdiction in which the plans operate. This annual amount is dependent upon numerous actuarial assumptions. For additional information, see Note 12: ''Employee Benefit Plans'', "Note 8: ''Balance Sheet Information'' and Note 16: ''Income Taxes'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K.

Key Financing and Capital Events

Overview

For the past several years, we have undertaken various measures to secure liquidity to pursue acquisitions, repurchase shares of our common stock, reduce interest costs, amend existing key financing arrangements and, in some cases, extend a portion of our debt maturities to continue to provide us additional operating flexibility. Certain of these measures continued in 2021. Set forth below is a summary of certain key financing events affecting our capital structure during the last three years. For further discussion of our debt instruments, see Note 9: ''Long-Term Debt'' and for further discussion on the Share Repurchase Program (as defined below), see Note 10: ''Earnings Per Share and Equity'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K.

2021 Financing Events

Issuance of 0% Convertible Senior Notes due 2027

On May 19, 2021, we completed a private offering of $805.0 million aggregate principal amount of 0% Notes, the proceeds of which were used to repurchase a portion of the 1.625% Notes in privately negotiated note repurchase or exchange transactions, repay a portion of the Revolving Credit Facility, pay the net cost of the related convertible note hedges after such costs were offset by the proceeds from the related sale of warrants (each described below), and general corporate purposes. The 0% Notes will mature on May 1, 2027, unless earlier repurchased or redeemed by the Company or converted pursuant to their terms.

The initial conversion rate of the 0% Notes is 18.8796 shares of common stock per $1,000 principal amount, which is equivalent to an initial conversion price of approximately $52.97 per share of common stock. We may redeem all or any portion of the 0% Notes, the holders may convert their 0% Notes and the conversion rate is subject to adjustment, in each case upon the occurrence of certain specified events as set forth in the Indenture governing the 0% Notes. We incurred issuance costs of $19.0 million in connection with the issuance of the 0% Notes, of which $15.7 million was capitalized as debt issuance costs and $3.3 million was allocated to the conversion option and recorded to stockholders’ equity. The debt discount and debt issuance costs are being amortized at an effective interest rate of 3.2% over the contractual term of the 0% Notes.

In connection with the issuance of the 0% Notes, we entered into convertible note hedge transactions with respect to our common stock with the initial purchasers of the 0% Notes or their affiliates ("Counterparties") and paid $160.3 million in cash for the convertible note hedges, which was recorded to stockholders’ equity. We also entered into warrant transactions with the Counterparties and received $93.8 million in cash for the sale of warrants, which was recorded to stockholders’ equity.

Partial exchange or repurchase of the 1.625% Notes

On May 11, 2021, contemporaneously with the issuance of the 0% Notes, we entered into separate privately negotiated transactions with certain holders of the 1.625% Notes to repurchase or exchange, as applicable, $372.4 million in aggregate

39

principal amount of the 1.625% Notes for a total consideration of $506.5 million in cash and 5.4 million shares of the Company’s common stock. On December 10, 2021, we repurchased $47.4 million of the 1.625% Notes for $47.4 million in cash and 1.6 million shares of common stock.

Repayments under the Revolving Credit Facility

During the year ended December 31, 2021, we repaid the outstanding balance of $700.0 million under the Revolving Credit Facility using a portion of the net proceeds from the issuance of the 0% Notes and cash generated from operations. As of December 31, 2021, we had approximately $1.97 billion available under the Revolving Credit Facility for future borrowings.

2020 Financing Events

Maturity and Settlement of 1.00% Notes due 2020

The 1.00% Notes matured on December 1, 2020. The maturity of the notes resulted in us paying $690.0 million in cash, representing the principal portion of the 1.00% Notes, to holders of the 1.00% Notes using our available cash and cash equivalents. The excess over the principal amount was settled by issuing shares of common stock held in treasury. At the time of issuance of the 1.00% Notes, we concurrently entered into hedge transactions with certain of the initial purchasers of the 1.00% Notes, and accordingly, repurchased an equivalent number of shares of our common stock at fair market value, to effectively offset the issuance of shares.

Also at the time of issuance of the 1.00% Notes, we sold warrants to certain bank counterparties whereby the holders of the warrants had the option to purchase from us the equivalent number of shares of our common stock at a price of $25.96 per share. All these warrants were exercised by the holders during the first and second quarters of 2021 and were settled by issuing an aggregate of 13.4 million shares of common stock.

Issuance of 3.875% Notes

On August 21, 2020, we completed a private offering of $700.0 million aggregate principal amount of the 3.875% Notes. The 3.875% Notes bear interest at a rate of 3.875% per year, payable semi-annually on March 1 and September 1 of each year, beginning on March 1, 2021, and will mature on September 1, 2028, unless earlier redeemed or repurchased by us. In connection with the issuance, we incurred original issue discount and debt issuance costs amounting to $9.4 million, which has been capitalized and will be amortized to interest expense through the maturity date of September 1, 2028. The net proceeds from the issuance of the 3.875% Notes were used entirely to repay borrowings under the Revolving Credit Facility.

Borrowing and repayment under the Revolving Credit Facility

On March 24, 2020, we borrowed $1,165.0 million under the Revolving Credit Facility as a precautionary measure in order to increase the Company’s cash position and provide financial flexibility in light of the uncertainty resulting from the impact of the COVID-19 pandemic. Due to better macroeconomic and business conditions, on August 21, 2020, we used the net proceeds from the issuance of the 3.875% Notes along with cash on hand to repay $1,200.0 million of outstanding borrowings. Additionally, on December 31, 2020, we repaid $65.0 million of outstanding borrowings under the Revolving Credit Facility.

Share Repurchase Program

During 2020, we repurchased 3.6 million shares of our common stock for an aggregate purchase price of $65.3 million pursuant to the Share Repurchase Program.

2019 Financing Events

Amendments to the Amended Credit Agreement

On June 12, 2019, we entered into the Fifth Amendment to the Amended Credit Agreement (the "Fifth Amendment") and on June 19, 2019, drew $900.0 million of the Revolving Credit Facility to partially fund the acquisition of Quantenna. On August 15, 2019, we entered into the Sixth Amendment to the Amended Credit Agreement (the "Sixth Amendment") which increased amounts that may be borrowed under the Revolving Credit Facility by $70.0 million to $1.97 billion. On September 19, 2019, we entered into the Seventh Amendment to the Amended Credit Agreement (the "Seventh Amendment") and utilized the additional borrowings pursuant to the Seventh Amendment to repay $500.5 million of the outstanding balance under the Revolving Credit Facility.

40

Share Repurchase Program

During 2019, we repurchased 7.8 million shares of our common stock for an aggregate purchase price of $138.9 million pursuant to the Share Repurchase Program.

Debt Guarantees and Related Covenants

As of December 31, 2021, we were in compliance with the indentures relating to our 0% Notes, 3.875% Notes and 1.625% Notes and with covenants relating to our Term Loan "B" Facility and Revolving Credit Facility. Our 0% Notes, 3.875% Notes and 1.625% Notes are senior to the existing and future subordinated indebtedness of onsemi and our guarantor subsidiaries and rank equally in right of payment to all of our existing and future senior debt and as unsecured obligations and are subordinated to all of our existing and future secured debt to the extent of the assets securing such debt.

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.

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) 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; and (iv) assumptions used in business combinations. Additionally, during periods where it becomes applicable, significant estimates will be used by management in determining the future cash flows used to assess and test for impairment of long-lived assets and goodwill. Actual results may differ from the estimates and assumptions used in the consolidated financial statements.

Revenue. 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 recognize revenue when we satisfy a performance obligation in an amount reflecting the consideration to which we expect to be entitled. 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 apply a five-step approach in determining the amount and timing of revenue to be recognized: (1) identifying the contract with a customer; (2) identifying the performance obligations in the contract; (3) determining the transaction price; (4) allocating the transaction price to the performance obligations in the contract; and (5) 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. Substantially all of our revenue is recognized at the time control of the products transfers to the customer.

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.

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 are recognized,

41

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. 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. However, 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 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. 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 to our effective tax rate.

Business Combination. 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.

42

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 resulting in a portion of goodwill or other assets being de-recognized, and which may or may not 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.

Recent Accounting Pronouncements

For a discussion of recent accounting pronouncements, see Note 4: ''Recent Accounting Pronouncements'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K.

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, 2021, our gross long-term debt (including current maturities) totaled $3,258.3 million. We have no interest rate exposure to rate changes on our fixed rate debt, which totaled $3,160.1 million. We do have interest rate exposure with respect to the $98.2 million balance of our variable interest rate debt outstanding as of December 31, 2021. A 50 basis point increase in interest rates would impact our expected annual interest expense for the next 12 months by approximately $4.2 million. However, some of this impact would be offset by additional interest earned on our cash and cash equivalents should rates on deposits and investments also increase. Our interest rate swaps hedge the majority of the risk of variability in cash flows resulting from future interest payments on our variable interest rate debt.

While we have observed stabilization in the capital markets impacted by the COVID-19 pandemic, there can be no assurance that equity or borrowings will be available when we access the capital markets again or, if available, will be at rates or prices acceptable to us.

To ensure the adequacy and effectiveness of our foreign exchange hedge positions, we continually monitor our foreign exchange forward positions, both on a stand-alone basis and in conjunction with their underlying foreign currency exposures, from an accounting and economic perspective. 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

43

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, 2021 and 2020 was $288.3 million and $263.4 million, respectively. Our policies prohibit speculation on financial instruments, trading in currencies for which there are no underlying exposures, or entering into trades for any currency to intentionally increase the underlying exposure.

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 results would have impacted our income before taxes by approximately $143.7 million for the year ended December 31, 2021, 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 8.    Financial Statements and Supplementary Data

Our consolidated Financial Statements listed in the index appearing under Part IV, Item 15(a)(1) of this Form 10-K and the Financial Statement Schedule listed in the index appearing under Part IV, Item 15(a)(2) of this Form 10-K are filed as part of this Form 10-K and are incorporated herein by reference in this Item 8.

Item 9.    Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

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 in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the required time periods and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required 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, 2021.

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, 2021 which 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

44

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, 2021. 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, 2021.

Management's assessment of the effectiveness of internal control over financial reporting as of December 31, 2021 excluded GT Advanced Technologies Inc. ("GTAT"), which was acquired by the Company on October 28, 2021. GTAT is a wholly-owned subsidiary of the Company and represented 0.7% and 0.1% of total assets and total revenue, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2021.

The effectiveness of our internal control over financial reporting as of December 31, 2021 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, 2021 and 2020, 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, 2021, 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, 2021, 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, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021 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, 2021, 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.

As described in Management’s Report on Internal Control Over Financial Reporting, management has excluded GT Advanced Technologies Inc. from its assessment of internal control over financial reporting as of December 31, 2021, because it was acquired by the Company in a purchase business combination during 2021. We have also excluded GT Advanced Technologies Inc. from our audit of internal control over financial reporting. GT Advanced Technologies Inc. is a wholly-owned subsidiary whose total assets and total revenue excluded from management’s assessment and our audit of internal control over financial reporting represent 0.7% and 0.1%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2021.

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

54

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 matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate 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 matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Ship and Credit Reserves

As described in Notes 2 and 8 to the consolidated financial statements, the Company’s ship and credit reserves are $163.8 million as of December 31, 2021. Sales returns and allowances, which include ship and credit reserves for distributors, are estimated by management based on historical claims data and expected future claims. Provisions for ship and credit claims are provided for in the same period the related revenue is recognized, and are netted against revenue.

The principal considerations for our determination that performing procedures relating to ship and credit reserves is a critical audit matter are the significant judgment by management in estimating the reserves, which in turn led to significant auditor judgment, subjectivity and effort in performing procedures to evaluate management’s expected future claims assumptions.

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 ship and credit reserves. These procedures also included, among others (i) testing management’s process for determining the estimate, (ii) evaluating the appropriateness of the approach used by management in developing the estimate, (iii) evaluating the reasonableness of the expected future claims assumptions, and (iv) testing the completeness and accuracy of historical claims data. Evaluating the assumptions related to the expected future claims involved evaluating whether the assumptions used were reasonable considering the past claim activity.

Valuation of Inventories

As described in Notes 2 and 8 to the consolidated financial statements, the Company’s inventory balance of $1,379.5 million as of December 31, 2021, 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 significant 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

55

other areas of the audit.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1: Background and Basis of Presentation

ON Semiconductor Corporation, together with its wholly and majority-owned subsidiaries (the "Company"), prepares its consolidated financial statements in accordance with GAAP. As of December 31, 2021, the Company was organized into three operating segments, which also represent its three reportable segments: PSG, ASG and ISG.

Unless otherwise noted, all dollar amounts are in millions, except per share amounts. Certain reclassifications have been made to prior period amounts to conform to current-period presentation.

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) 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; and (iv) assumptions used in business combinations. Additionally, during periods where it becomes applicable, significant estimates will be used by management in determining the future cash flows used to assess and test 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.

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. However, the majority of product inventory that has been previously written down is ultimately discarded. Although the Company does sell some products that have 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 3-10 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 expense is 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.

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, which are considered long-lived assets are amortized over their estimated useful lives and

62

ON SEMICONDUCTOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

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 for which the right-of-use ("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 in the Consolidated Balance Sheet.

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 Facility 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.

Contingencies

The Company is involved in a variety of legal matters, IP matters, 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.

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. 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. For product development agreements, the Company has identified the completion of a service defined in the agreement as the performance obligation. The Company applies a five-step approach in determining the amount and timing of revenue to be recognized: (1) identifying the contract with a customer; (2) identifying the performance obligations in the contract; (3) determining the transaction price; (4) allocating the transaction price to the performance obligations in the contract; and (5) recognizing revenue when the performance obligation is satisfied.

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. The Company considers the customer purchase orders, governed by sales agreements or the Company’s standard terms and

63

ON SEMICONDUCTOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

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 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. 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.

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. The Company recognizes revenue from product development agreements over time based on the cost-to-cost method. 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 Company’s performance obligation being satisfied, which represents a contract liability. Contract liabilities are recognized as revenue when the performance obligations are satisfied. 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 are recognized, and are netted against revenue.

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 are not disclosed. The Company records freight and handling costs associated with outbound freight after control over a product has 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 to 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.

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, which 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: Revenue and Segment Information

Revenue recognized for product sales amounted to $6,719.9 million, $5,227.8 million and $5,492.0 million for the years ended December 31, 2021, 2020 and 2019, respectively. Revenue recognized for product development agreements amounted to $19.9 million, $27.2 million and $25.9 million for the years ended December 31, 2021, 2020 and 2019, respectively.

In connection with long-term supply arrangements, the Company received capacity payments and deposits of $57.1 million during the year ended December 31, 2021, which was recorded as a contract liability, and $11.5 million was recorded as a corresponding receivable. During the year ended December 31, 2021, the Company recognized an immaterial amount of revenue by satisfying the performance obligations associated with these contract liabilities, and the remaining balances amounting to $25.8 million and $30.0 million are recorded as current liabilities and other long-term liabilities, respectively, in the Consolidated Balance Sheet. The Company has not recorded any contract assets as of December 31, 2021. There were no corresponding amounts for the years ended and as of December 31, 2020 and December 31, 2019.

A significant portion of the Company’s orders are firm commitments that are non-cancellable, including orders or contracts

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

with a duration of less than one year. Certain of the Company’s customer contracts are multi-year agreements which includes firmly committed amounts for which the remaining performance obligations as of December 31, 2021 were approximately $8.6 billion (excluding the remaining performance obligations for contracts having a duration of one year or less). The Company expects to recognize approximately 25% of this amount as revenue during the next twelve months upon shipment of products under these contracts. Total sales estimates are based on negotiated contract prices and demand quantities, and could be influenced by manufacturing and supply chain constraints, among other things. Accordingly, the amount represented by remaining performance obligations may not be indicative of the actual revenue recognized for future periods.

The Company is organized into three operating and reportable segments consisting of PSG, ASG and ISG. The operating costs of manufacturing facilities which service all business units are reflected in the segments' 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. In addition to the operating and reportable segments, the Company also operates global operations, sales and marketing, information systems and finance and administration groups. A portion of the expenses for each of these groups are allocated to the segments based on specific and general criteria.

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

	PSG		ASG		ISG		Total
For year ended December 31, 2021:
Revenue from external customers	$	3,439.1	$	2,399.9	$	900.8	$	6,739.8

_______________________

(1)Beginning in 2021, the Company started including unallocated manufacturing costs as part of segment operating results to determine segment gross profit. As a result, the prior-period amounts have been reclassified to conform to current-period presentation.

The Company had one customer, a distributor, whose revenue accounted for approximately 13% and 11% of the total revenue for the years ended December 31, 2021 and December 31, 2020, respectively. There were no customers whose revenue exceeded 10% or more of total revenue for the year ended December 31, 2019.

The Company operates in various geographic locations. Sales to unaffiliated customers have little correlation with the location of manufacturers. It is, therefore, not meaningful to present operating profit by geographical location. 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 are not specifically ascribed to its individual reportable segments. Rather, assets used in operations are generally shared across the Company’s operating and reportable segments.

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.

Note 4: Recent Accounting Pronouncements

Pending Adoption:

ASU 2021-10 - Government Assistance (Topic 832) - Disclosures by Business Entities about Government Assistance ("ASU 2021-10")

In November 2021, the FASB issued ASU 2021-10, which is aimed at increasing transparency about certain government assistance received by a business entity. The standard requires business entities to make annual disclosures about the nature of the transactions and the related accounting policy used to account for the transactions, the line items and applicable amounts on the balance sheet and income statement that are affected by the transactions, and significant terms and conditions of the transactions, including commitments and contingencies. If an entity omits any required disclosures because it is legally prohibited, it must disclose that fact. ASU 2021-10 is effective for financial statements issued for annual periods beginning after December 15, 2021. The Company expects the standard to be applicable to its financial statements and is currently evaluating and understanding the requirements for drafting applicable disclosures.

ASU 2020-06 - Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity ("ASU 2020-06")

In August 2020, the FASB issued ASU 2020-06, which simplifies the guidance on the issuer’s accounting for convertible debt instruments by removing the separation models for (1) convertible debt with a cash conversion feature and (2) convertible instruments with a beneficial conversion feature. Entities will not separately present in equity an embedded conversion feature in such debt and will account for a convertible debt instrument wholly as debt, unless certain other conditions are met. Also, ASU 2020-06 requires the application of the if-converted method for the purpose of calculating diluted earnings per share and the treasury stock method will be no longer available. As required, the Company plans to adopt ASU 2020-06 for fiscal 2022 using a modified retrospective approach and expects to record a cumulative effect adjustment of an estimated $66 million to increase opening retained earnings as of January 1, 2022. Due to the adoption of ASU 2020-06, the Company expects interest expense for fiscal 2022 will be lower than for fiscal 2021 by approximately $27 million. At an average stock price of $55, the Company expects an increase of 2.8 million for fiscal 2022 compared to fiscal 2021 in dilutive shares included in diluted weighted-average shares of common stock outstanding for the purpose of calculating diluted earnings per share. These estimates are based on the balance of 1.625% Notes and 0% Notes outstanding as of December 31, 2021.

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 years ended December 31, 2021, 2020 and 2019, the Company incurred acquisition and divestiture related costs of approximately of $11.9 million, $1.0 million and $11.3 million, respectively, which are included in operating expenses in the Company's Consolidated Statements of Operations and Comprehensive Income. Following are the acquisitions and divestitures during 2021, 2020 and 2019.

2021 Acquisition and Divestiture

GTAT Acquisition

On October 28, 2021, the Company acquired all of outstanding equity interests of GTAT. The Company believes the acquisition of GTAT will act as a building block to fuel growth and accelerate innovation in disruptive intelligent power technologies and secure supply of SiC to meet growing customer demand for SiC-based solutions in the sustainable ecosystem.

Pursuant to the terms and subject to the conditions set forth in the Agreement and Plan of Merger, the purchase price totaled $434.9 million. Cash consideration amounted to $424.6 million, of which $17.0 million was deposited for general representation and warranty purposes in an escrow account, legally owned by the Company. The remaining consideration of approximately $10.0 million represented the value of certain pre-acquisition deposits and payable balances effectively settled between the parties since the Company was GTAT's customer. From the closing date of the acquisition through December 31, 2021, the Company recognized immaterial revenue and net loss relating to GTAT.

The preliminary allocation of the purchase price of GTAT to the assets acquired and liabilities assumed based on their relative fair values is as follows (in millions):

	Purchase Price Allocation
Cash and cash equivalents	$	8.2
Inventory and other current assets	10.0
Property, plant and equipment	31.9
Goodwill	274.8
Intangible assets - Developed Technology	130.0
Deferred tax assets	13.4
Other non-current assets	7.4
Total assets acquired	475.7
Current liabilities	5.8
Other long-term liabilities	35.0
Total liabilities assumed	40.8
Net assets acquired/purchase price	$	434.9

Developed technology of $130.0 million, determined using the income approach is estimated to have an useful life of 13 years. There were no IPRD intangible assets identified. The acquisition produced $274.8 million of goodwill, which has been assigned to a reporting unit within PSG. Goodwill is attributable to the expected value generation by GTAT by being part of the Company along with a more meaningful engagement by the customers due to the scale of the combined entities, GTAT's assembled workforce, other product and operating synergies. Goodwill arising from the GTAT acquisition is not deductible for tax purposes.

The purchase price allocation is considered preliminary as the Company finalizes its determination relating to the valuation of assets and liabilities and finalizes key assumptions, approaches and judgements with respect to intangible assets acquired from GTAT and the related tax effects.

GTAT Pro-Forma Results of Operations

The following unaudited pro-forma consolidated results of operations for the years ended December 31, 2021 and December 31, 2020 have been prepared as if the acquisition of GTAT had occurred on January 1, 2020 and includes adjustments for the effect of fair value changes, transaction costs, taxation and financial structure (in millions):

Divestiture

On October 1, 2021, the Company divested itself of one of its businesses along with the related intellectual property for aggregate consideration of approximately $13.6 million and recognized a gain of $10.2 million after offsetting the carrying values of the disposed assets and liabilities.

Pending Acquisition, announced in 2019

During 2019 and 2020, the Company entered into an APA and an APA Amendment, respectively, to acquire GFUS's East Fishkill, New York site and fabrication facilities and certain other assets and liabilities on or around December 31, 2022 for an aggregate purchase price of $400.0 million in cash, subject to adjustments as described in the APA and APA amendment (the "Total Consideration"). In connection with the APA Amendment, the Company also entered into an amendment to an ancillary agreement relating to the provision of foundry services entered into in connection with the execution of the APA, which provided the Company certain additional tools and flexibility in its capital expenditures and manufacturing plans for 2021 and 2022.

The Company made payments of $100.0 million and $70.0 million during 2020 and 2019, respectively, of the Total Consideration in cash as a non-refundable deposit, which will be applied toward and reduce the Total Consideration. These amounts are recorded as other assets in the Consolidated Balance Sheets. Additionally, Company paid GFUS a license fee of $30.0 million in cash for certain technology during 2019, which has been recognized as an intangible asset subject to amortization.

Quantenna Acquisition during 2019

On June 19, 2019, the Company acquired 100% of the outstanding shares of Quantenna, a global leader and innovator of high performance Wi-Fi solutions, whereby Quantenna became a wholly-owned subsidiary of the Company. Following the acquisition, Quantenna changed its name to ON Semiconductor Connectivity Solutions, Inc. The purchase price consideration for the acquisition totaled $1,039.3 million, and was funded by a combination of a draw of $900.0 million against the Revolving Credit Facility and cash on hand. The operations of Quantenna have since been integrated with that of the Company.

Other current liabilities	17.5
Deferred tax liabilities	3.3
Other non-current liabilities	15.4
Total liabilities assumed	58.8
Net assets acquired/purchase price	$	1,039.3

Acquired intangible assets of $110.9 million include developed technology of $58.3 million (which are estimated to have a useful life of eight years). The value assigned to developed technology was determined using the income approach. The total weighted average amortization period for the acquired intangibles is eight years.

IPRD assets are amortized over the estimated useful life of the assets upon successful completion of the related projects. The value assigned to IPRD was determined by estimating the net cash flows from the projects when completed and discounting the net cash flows to their present value using a discount rate of approximately 12.0%. The cash flows from IPRD’s significant products commenced from 2020 onwards.

The acquisition produced $726.7 million of goodwill, which was assigned to a reporting unit within ASG. The goodwill is attributable to a combination of Quantenna's assembled workforce, expectations regarding a more meaningful engagement by the customers due to the scale of the combined company and other product and operating synergies. Goodwill arising from the Quantenna acquisition is not deductible for tax purposes.

Note 6: Goodwill and Intangible Assets

Goodwill

Goodwill is tested for impairment at the reporting unit level, which is one level below the Company's operating segments. The Company performed its impairment assessment and concluded that the fair value of reporting units exceed their carrying value as of the impairment test date. As the Company continues to implement its business strategy to rationalize products and manufacturing locations to transition to a lighter internal fabrication model, there could be divestiture transactions resulting in a portion of goodwill or other assets being de-recognized, and which may or may not result in accounting charges.

The following table summarizes goodwill by operating and reportable segments (in millions):

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

Following the acquisition of Quantenna and during the quarter ended June 28, 2019, the Company implemented a cost-reduction plan resulting in the elimination of approximately eight executive positions from Quantenna’s workforce, primarily as a result of redundancies. During the year ended December 31, 2019, the Company terminated an additional ten employees. The total restructuring expense of $15.7 million was attributable to the accelerated vesting of stock awards previously issued by Quantenna, executive retention and other severance benefits.

0% Convertible Senior Notes due 2027

On May 19, 2021, the Company completed a private offering of $805.0 million aggregate principal amount of its 0% Notes, the proceeds of which were used to repurchase a portion of the 1.625% Notes in privately negotiated note repurchase or exchange transactions, repay a portion of the Revolving Credit Facility, pay the net cost of the related convertible note hedges after such costs were offset by the proceeds from the sale of warrants, and general corporate purposes. The 0% Notes were offered to qualified institutional buyers in accordance with Rule 144A under the Securities Act, and were issued under an indenture (the "0% Indenture") by and among the Company, the guarantors party thereto, and Wells Fargo Bank, National Association, as

trustee, which provides, among other things, that the 0% Notes will mature on May 1, 2027, unless earlier repurchased or redeemed by the Company or converted pursuant to their terms. On or after February 1, 2027, until the close of business on the second scheduled trading day immediately preceding May 1, 2027, holders may convert their 0% Notes at any time. The 0% Notes are the Company’s senior unsecured obligations and are fully and unconditionally guaranteed, on a joint and several basis, by each of the Company’s subsidiaries that is a borrower or guarantor under the Company’s Amended Credit Agreement. The Company may satisfy any conversion elections by paying cash up to the aggregate principal amount of the 0% Notes to be converted, and paying or delivering, as the case may be, cash, shares of common stock or a combination of cash and shares of common stock, at the Company’s election, in respect of the remainder, if any, of its conversion obligation in excess of the aggregate principal amount of the 0% Notes to be converted.

The initial conversion rate of the 0% Notes is 18.8796 shares of common stock per $1,000 principal amount, which is equivalent to an initial conversion price of approximately $52.97 per share of common stock. The Company may redeem for cash all or any portion of the 0% Notes, at the Company’s option, on or after May 1, 2024, if the last reported sale price of the Company’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days during any consecutive 30 trading-day period. Prior to February 1, 2027, the holders may convert their 0% Notes under the following circumstances: (i) during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days during the period of 30 consecutive trading days ending on 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 0% Notes for each trading day of such period was less than 98% of the product of the last reported sale price of Company’s common stock and the conversion rate on each such trading day; (iii) if the Company calls any or all of the 0% 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 the 0% Indenture.

The conversion rate is subject to adjustment upon the occurrence of certain specified events as set forth in the 0% Indenture. The maximum number of shares of common stock issuable in connection with the conversion is 21.7 million. In accordance with the accounting guidance on embedded conversion features, the Company valued and bifurcated the conversion option, representing the debt discount, from the respective host debt instrument and recorded $139.9 million to stockholders’ equity. The debt discount represented the borrowing rate for non-convertible debt as of the date of issuance with similar maturity. The Company also incurred issuance costs of $19.0 million, of which $15.7 million was capitalized as debt issuance costs and $3.3 million was allocated to the conversion option and recorded to stockholders’ equity. The debt discount and debt issuance costs are being amortized at an effective interest rate of 3.2% over the contractual term of six years under the existing accounting standard. The carrying amount of the equity component, unamortized discount and issuance costs, and the net carrying amount of the liability component as of December 31, 2021 were $143.2 million, $140.2 million and $664.8 million, respectively. The interest cost relating to the amortization of debt discount and issuance costs recognized during the year ended December 31, 2021 was $15.3 million. The 0% Notes's if-converted value exceeded its principal amount by $227.2 million as of December 31, 2021, calculated using the stock price on that date.

In addition, the Company entered into convertible note hedge transactions with respect to the common stock with the initial purchasers of the 0% Notes or their affiliates ("Counterparties"). The convertible note hedges cover, subject to customary anti-dilution adjustments, the number of shares of common stock that initially underlie the 0% Notes, and 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. The Company paid $160.3 million in cash for the convertible note hedges and recorded them as a reduction to stockholders’ equity. The Company applied ASC 815-40 - "Derivatives and Hedging - Contracts in Entity's Own Equity" and concluded that the convertible note hedges should be classified in stockholders’ equity with no subsequent remeasurement.

The Company also entered into warrant transactions with the Counterparties, whereby the Company sold warrants to acquire, subject to anti-dilution adjustments, the same number of shares of the Company’s common stock covered by the convertible note hedges at an initial strike price of $74.34 per share, which represents a 100% premium over the closing price of $37.17 per share on May 11, 2021. The maximum number of shares of common stock issuable in connection with the warrants is 30.4 million. The Company analyzed the transaction under ASC 815-40 - "Derivatives and Hedging - Contracts in Entity's Own Equity" and determined that the instrument met the criteria for classification as an equity transaction with no subsequent remeasurement. The Company received $93.8 million in cash for the sale of warrants, which was recorded as an increase to stockholders’ equity.

Amendments to the Amended Credit Agreement

The Company entered into the Amended Credit Agreement in 2016 which provides for a $1.97 billion revolving credit facility (the "Revolving Credit Facility") and a $2.4 billion term loan "B" facility (the “Term Loan "B" Facility”). Between 2016 and 2021, the Company, the Guarantors (as defined in the Amended Credit Agreement), the several lenders party thereto and the Agent (as defined in the Amended Credit Agreement) entered into nine amendments to the Amended Credit Agreement. These amendments, among others, reduced the interest rates payable and increased the amounts that may be borrowed under the Term Loan "B" Facility and the Revolving Credit Facility and also amended certain financial covenants.

On May 10, 2021, in anticipation of the issuance of the 0% Notes, the Company entered into the Ninth Amendment ("Ninth Amendment") to the Amended Credit Agreement. The Ninth Amendment provided for, among other things, modifications to the Amended Credit Agreement to permit the issuance of the 0% Notes and the repurchase or exchange of the 1.625% Notes, remove the availability of borrowings in currencies other than U.S. dollars in light of the unavailability of LIBO Rate for such other currencies beginning December 31, 2021, provide for increased capacity to dispose of certain assets, make investments and incur certain types of indebtedness and liens, increase the threshold for real estate properties required to be mortgaged to secure the facility, increase the ability to incur incremental debt facilities and remove certain conditions applicable to the incurrence of incremental facilities. There was no impact to the consolidated financial statements due to the Ninth Amendment.

On June 23, 2020, the Company entered into the Eighth Amendment ("Eighth Amendment") to the Amended Credit Agreement to change certain defined terms and to modify certain terms and conditions of the Amended Credit Agreement to align with the domestication of certain foreign subsidiaries. There was no impact to the consolidated financial statements due to the Eighth Amendment. See Note 16: ''Income Taxes'' for additional information on the domestication.

The obligations under the Amended Credit Agreement are guaranteed by the Guarantors and collateralized by a pledge of substantially all of the assets of the Company and the Guarantors, including a pledge of the equity interests in certain of the Company’s domestic and first tier foreign subsidiaries, subject to customary exceptions. The obligations under the Amended Credit Agreement are also collateralized by mortgage on certain real property assets of the Company and its domestic subsidiaries.

The Amended Credit Agreement includes a maximum total net leverage ratio as a financial maintenance covenant, which the Company was in compliance as of December 31, 2021. It also contains other customary affirmative and negative covenants and events of default.

Partial repurchase or exchange of the 1.625% Notes/Loss on debt refinancing and prepayment

On May 11, 2021, contemporaneously with the issuance of the 0% Notes, the Company entered into separate privately negotiated transactions with certain holders of the 1.625% Notes to repurchase or exchange, as applicable, $372.4 million in aggregate principal amount of the 1.625% Notes for a total consideration of $506.5 million in cash and 5.4 million shares of the Company’s common stock. The repurchases and exchanges resulted in a loss on debt prepayment of $26.2 million based on the fair value of the debt component, while the remainder of the consideration amounting to $141.6 million attributable to the equity component was recorded to stockholders’ equity. Separately, the Company received 9.1 million shares into treasury by terminating a portion of the convertible note hedge transactions that were originally entered at the time of issuance of the 1.625% Notes in a notional amount corresponding to the principal amount of the 1.625% Notes repurchased or exchanged and recorded $339.0 million to additional paid-in capital and treasury stock, with no overall impact to equity. Additionally, the Company terminated a portion of the warrant transactions originally entered at the time of issuance of the 1.625% Notes and issued 6.8 million shares with respect to a number of shares of common stock equal to the notional shares underlying such 1.625% Notes repurchased or exchanged.

On December 14, 2021, the Company repurchased $47.4 million in principal of 1.625% Notes for total consideration of $47.4 million in cash and 1.6 million shares of the Company's common stock. This transaction resulted in a loss on debt prepayment of $2.8 million based on the fair value of the debt component, while the remainder of the consideration amounting to $0.8 million attributable to the equity component was recorded to stockholders’ equity. Separately, the Company received 1.6 million shares into treasury by terminating a portion of the convertible note hedge transactions that were originally entered at the time of issuance of the 1.625% Notes in a notional amount corresponding to the principal amount of the 1.625% Notes redeemed and recorded $102.2 million to additional paid-in capital and treasury stock, with no overall impact to equity. Additionally, the Company terminated a portion of the warrant transactions originally entered at the time of issuance of the 1.625% Notes and issued 1.3 million shares with respect to a number of shares of common stock equal to the notional shares underlying such 1.625% Notes redeemed.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

The remaining outstanding principal amount of the 1.625% Notes, amounting to $144.6 million, net of unamortized discount and issuance costs continues to be classified as a current portion of long-term debt as of December 31, 2021. Pursuant to the indenture governing the 1.625% Notes, because the last reported sale price of the Company’s common stock for at least 20 trading days during the period of 30 consecutive trading days ending on December 31, 2021 was greater than or equal to $26.94 (130% of the conversion price) on each applicable trading day, the holders have the right to surrender any portion of their 1.625% Notes (in minimum denominations of $1,000 in principal amount or an integral multiple thereof) for conversion during the calendar quarter ending March 31, 2022, and only during such calendar quarter.

The carrying amount of the equity component, unamortized discount and issuance costs, and the net carrying amount of the liability component as of December 31, 2021 were $31.2 million, $10.5 million and $144.6 million, respectively. The carrying amount of the equity component, unamortized discount and issuance costs, and the net carrying amount of the liability component as of December 31, 2020 were $115.7 million, $59.4 million and $515.6 million, respectively. Total interest expense relating to the coupon rate and amortization of debt discount and issuance costs recognized during the years ended December 31, 2021, 2020 and 2019 were $19.6 million, $28.7 million and $29.4 million, respectively.

The conversion rate of the 1.625% Notes is 48.2567 shares of common stock per $1,000 principal amount of 1.625% Notes (subject to adjustment in certain events), which is equivalent to a conversion price of approximately $20.72 per share of common stock. The unamortized discount and issuance costs are amortized at an effective interest rate of 5.27% over the remaining contractual term of approximately two years under the existing accounting standard. The convertible note hedge transactions and warrants issued in connection with the issuance of the 1.625% Notes were originally classified in stockholders' equity with no subsequent remeasurement using the guidance in ASC 815-40 - "Derivatives and Hedging - Contracts in Entity's Own Equity". The 1.625% Notes's if-converted value exceeded its principal amount by $353.4 million as of December 31, 2021, calculated using the stock price on that date.

Revolving Credit Facility

During the year ended December 31, 2021, the Company repaid the outstanding balance of $700.0 million under the Revolving Credit Facility using a portion of the net proceeds from the issuance of the 0% Notes and cash generated from operations. As of December 31, 2021, the Company had approximately $1.97 billion available under the Revolving Credit Facility for future borrowings, except for amounts utilized for letters of credit.

During the year ended December 31, 2020, the Company borrowed $1,165.0 million under the Revolving Credit Facility as a precautionary measure in order to increase the Company’s cash position and provide financial flexibility in light of the uncertainty resulting from the impact of the COVID-19 pandemic. During the third quarter of 2020, due to better macroeconomic and business conditions, the Company used the net proceeds from the issuance of the 3.875% Notes along with cash on hand to repay $1,200.0 million of outstanding borrowings under the Revolving Credit Facility. Additionally, on December 31, 2020, the Company repaid $65.0 million of outstanding borrowings under the Revolving Credit Facility.

Issuance of 3.875% Notes

On August 21, 2020, the Company completed its private offering of $700.0 million aggregate principal amount of the 3.875% Notes. The 3.875% Notes were offered in the United States to qualified institutional buyers pursuant to Rule 144A under the Securities Act and outside the United States pursuant to Regulation S under the Securities Act. The 3.875% Notes are fully and unconditionally guaranteed, on a joint and several basis, by each of the Company’s subsidiaries that is a borrower or Guarantor under the Amended Credit Agreement and will also be fully and unconditionally guaranteed by any of the Company’s subsidiaries that becomes a borrower or guarantees any indebtedness under the Amended Credit Agreement in the future.

The 3.875% Notes and the guarantees thereof are the Company’s and the Guarantors’ general unsecured obligations, respectively, and (i) rank equally in right of payment with all of the Company’s and the Guarantors’ existing and future senior indebtedness (including the 1.625% Notes); (ii) rank senior to any subordinated indebtedness that the Company or the Guarantors may incur; (iii) are effectively subordinated to all of the Company’s or the Guarantors’ existing and future secured indebtedness (including indebtedness under the Amended Credit Agreement), in each case, to the extent of the value of the assets securing such indebtedness; and (iv) are structurally subordinated in right of payment to all existing and future obligations of the Company’s subsidiaries that are not Guarantors of the 3.875% Notes.

The 3.875% Notes bear interest at a rate of 3.875% per year, payable semi-annually on March 1 and September 1 of each year, beginning on March 1, 2021, and will mature on September 1, 2028, unless earlier redeemed or repurchased by the Company. The original issue discount and debt issuance costs incurred by the Company in connection with the offering of the 3.875% Notes amounted to $9.4 million, which has been capitalized and will be amortized to interest expense through the maturity date

of September 1, 2028. The net proceeds from the issuance of the 3.875% Notes were used entirely to repay borrowings under the Revolving Credit Facility.

Maturity and Settlement of 1.00% Notes due 2020

The 1.00% Notes matured on December 1, 2020 and the Company paid $690.0 million in cash to holders, representing the principal portion of the 1.00% Notes, using the available cash and cash equivalents. The excess over the principal amount was settled by issuing shares of the Company's common stock held in treasury. The transaction resulted in a net impact of $88.7 million to additional paid-in capital and treasury stock, measured based on the acquisition cost of the reissued shares with no overall impact to equity. According to the terms of the hedge transactions entered at the time of issuance of the 1.00% Notes, on December 1, 2020, the Company repurchased an equivalent amount of shares of its common stock at the prevailing fair market value, to effectively offset the issuance of shares, which resulted in an impact of $321.0 million to additional paid-in capital and treasury stock, with no overall impact to equity.

At the time of issuance of the 1.00% Notes, the Company sold 37.3 million 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 $25.96 per share from the Company. During 2021, the warrant holders exercised these warrants and the Company settled them by issuing 13.4 million shares of common stock, on a net-share basis.

Note 10: Earnings Per Share and Equity

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,
	2021		2020		2019
Net income attributable to ON Semiconductor Corporation	$	1,009.6	$	234.2	$	211.7
Basic weighted-average shares of common stock outstanding	425.7		410.7		410.9
Add: Incremental shares for:
Dilutive effect of share-based awards	2.5		1.9		1.9
Dilutive effect of convertible notes and warrants	15.6		6.2		3.2
Diluted weighted average shares of common stock outstanding	443.8		418.8		416.0
Net income per share of common stock attributable to ON Semiconductor Corporation:
Basic	$	2.37	$	0.57	$	0.52
Diluted	$	2.27	$	0.56	$	0.51

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 0.3 million, 0.8 million and 0.8 million for the years ended December 31, 2021, 2020 and 2019, respectively.

The dilutive impact related to the Company’s 0% Notes, 1.625% Notes and 1.00% Notes for the period such notes were outstanding, has been determined in accordance with the net share settlement requirements. While the 0% Notes are repayable in cash up to the par value, in accordance with their terms, the Company has assumed the 1.625% Notes to be repayable in cash up to the par value in accordance with the existing accounting standards. The 1.00% Notes matured and were repaid and settled on December 1, 2020.

The excess over par value for the 0% Notes and 1.625% Notes, if applicable, has been assumed to be convertible into common stock. 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% Notes and 1.625% Notes when the stock price is above $52.97 and $20.72 per share, respectively. The dilutive impact of the warrants issued concurrently with the issuance of the 0% Notes, 1.625% Notes and 1.00% Notes with exercise prices of

$74.34, $30.70 and $25.96, respectively, has been included in the calculation of diluted weighted-average common shares outstanding, if applicable. All of the warrants issued in connection with the 1.00% Notes were settled during 2021.

While there were no repurchases under the Share Repurchase Program during the year ended December 31, 2021, the repurchases amounted to $65.3 million and $138.9 million during the years ended December 31, 2020 and December 31, 2019, respectively. As of December 31, 2021, the remaining authorized amount under the Share Repurchase Program was $1,295.8 million.

Reissuance of shares held in treasury stock

In connection with the maturity of the 1.00% Notes on December 1, 2020, the Company reissued shares of common stock held in treasury to settle the excess over the principal amount. This was the first time the Company reissued shares held in treasury stock and accounted for such reissuance on a first-in, first-out basis. Pursuant to the hedge transactions entered concurrently with the issuance of the 1.00% Notes, the Company acquired an equivalent number of shares of its common stock at the prevailing fair market value, to effectively offset the reissuance from treasury stock. This repurchase did not reduce the authorized amount remaining under the Share Repurchase Program.

Shares for Restricted Stock Units Tax Withholding

The amounts remitted during the years ended December 31, 2021, 2020 and 2019 were $38.9 million, $20.0 million and $33.5 million, respectively, for which the Company withheld approximately 0.9 million, 1.1 million and 1.6 million shares of common stock, respectively, that were underlying the RSUs that vested. None of these shares had been reissued or retired as of December 31, 2021 but may be reissued or retired later. These deemed repurchases in connection with tax withholding upon vesting were not made under the Share Repurchase Program, and the amounts spent in connection with such deemed repurchases did not reduce the authorized amount remaining under the Share Repurchase Program.

Non-Controlling Interest

Leshan operates assembly and test operations in Leshan, China. The Company owns 80% of the outstanding equity interests in Leshan, and the results of Leshan have been consolidated in the Company's financial statements. At December 31, 2021, the Leshan non-controlling interest balance was $19.0 million. This balance included the Leshan non-controlling interest's $1.6 million share of the earnings for the year ended December 31, 2021 offset by $2.2 million of dividend declared to the non-controlling shareholder. At December 31, 2020, the Leshan non-controlling interest balance was $19.6 million. This balance included the Leshan non-controlling interest's $2.2 million share of the earnings for the year ended December 31, 2020 offset by $5.0 million of dividends paid to the non-controlling shareholder.

ON Semiconductor Aizu Co. Ltd. ("OSA") operates a front-end wafer fabrication facility in Aizuwakamatsu, Japan. During 2020, the Company acquired the remaining equity interest in OSA from Fujitsu Semiconductor Limited ("FSL"), whereby OSA became a wholly-owned subsidiary of the Company. The purchase price payable to FSL for the remaining 40% equity, offset by the purchase price adjustment, resulted in the Company receiving $26.0 million in settlement of the purchase price from FSL during the year ended December 31, 2020. The results of OSA have been consolidated in the Company’s financial statements.

On June 7, 2020, the Company's Board of Directors authorized and declared a dividend of one preferred share purchase right (a "Right") for each outstanding share of common stock to the stockholders of record on June 18, 2020. The Rights, which continued to have a de minimis value from the time they were issued, expired on June 7, 2021.

Note 11: Share-Based Compensation

Total share-based compensation expense related to the Company's RSUs, stock grant awards and ESPP was recorded within the Consolidated Statements of Operations and Comprehensive Income as follows (in millions):

	Year Ended December 31,
	2021		2020		2019
Cost of revenue	$	15.6	$	11.5	$	10.6
Research and development	24.2		18.2		17.0

Income tax benefit	(21.3)		(14.2)		(16.7)
Share-based compensation expense, net of taxes	$	80.0	$	53.5	$	62.7

At December 31, 2021, total unrecognized share-based compensation expense, net of estimated forfeitures, related to non-vested RSUs with service, performance and market conditions was $92.6 million, which is expected to be recognized over a weighted-average period of 1.2 years. There was an insignificant amount of stock options exercised during the year ended December 31, 2021. Upon option exercise, 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 RSU and stock grant award is determined on the grant date. There were no employee stock options granted during the years ended December 31, 2021, 2020 and 2019. 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 6% for the year ended December 31, 2021 and 5% for the years ended December 31, 2020 and 2019.

Plan 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 or three 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, 2021, there was an aggregate of 42.2 million shares of common stock available for grant under the Amended and Restated SIP.

During 2021, the Company awarded 1.1 million RSUs 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 are recognized based on the grant date fair value irrespective of the achievement of the condition.

As of December 31, 2021, 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 $65.7 million, $7.5 million and $19.4 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 performance-based, service-based, and market-based RSUs was $92.9 million for the year ended December 31, 2021, which included $46.9 million for RSUs with time-based service conditions that were granted in 2021 and prior that are expected to vest.

Stock Grant Awards

During the year ended December 31, 2021, the Company granted 0.1 million shares of stock under stock grant awards to certain directors of the Company with immediate vesting at a weighted-average grant date fair value of $37.91 per share. Total compensation expense related to stock grant awards for the year ended December 31, 2021 was $2.0 million.

Employee Stock Purchase Plan

As of December 31, 2021, there were approximately 8.2 million shares available for issuance under the ESPP. Total compensation expense related to the ESPP for the year ended December 31, 2021 was $6.4 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 - Continued

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 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. For the year ended December 31, 2021, the Company recognized an actuarial gain of $21.4 million, while actuarial losses of $4.0 million and $15.6 million were recognized for the years ended December 31, 2020 and 2019, respectively. Of the actuarial gain for 2021, $18.4 million was primarily due to an increase in the discount rates while better than expected return on plan assets due to other changes in actuarial assumptions and plan experience amounted to $3.0 million.

Following is a summary of the status of the Company's foreign defined benefit pension plans and the net periodic pension cost ($ 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 remaining commitment of $230.0 million will be owed on or around December 31, 2022.

Environmental Contingencies

The Company’s headquarters in Phoenix, Arizona are located on property that is a "Superfund" site, which is a property listed on the National Priorities List and subject to clean-up activities under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA"). Motorola and Freescale (acquired by NXP Semiconductors N.V.) have been involved in the clean-up activities of on-site solvent contaminated soil and groundwater and off-site contaminated groundwater pursuant to consent decrees with the State of Arizona. As part of the Company’s separation from Motorola in 1999, Motorola retained responsibility for this contamination, and Motorola and Freescale have agreed to indemnify the Company with respect to remediation costs and other costs or liabilities related to this matter. Any costs to the Company in connection with this matter have not been, and, based on the information available, are not expected to be, material.

ON SEMICONDUCTOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued

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:

•Aizu, Japan. The Company’s former front-end manufacturing location in Aizu, Japan is located on property where soil and ground water contamination was detected. The Company believes that the contamination originally occurred during a time when the facility was operated by a prior owner. The Company worked with local authorities to implement a remediation plan and has completed remaining remediation. The majority of the cost of remediation was covered by insurance. During 2018, semi-annual groundwater monitoring indicated that the treatment was effective, and accordingly, we ceased such monitoring and have determined that this remediation project is complete.

•Czech Republic. The Company’s manufacturing facility in the Czech Republic has undergone remediation to respond to releases of hazardous substances that occurred during the years that this facility was operated by government-owned entities. The remediation projects consisted primarily of monitoring groundwater wells located on-site and off-site with additional action plans developed to respond in the event certain contamination levels are exceeded. The government of the Czech Republic has agreed to indemnify the Company and its respective subsidiaries, subject to specified limitations, for remediation costs associated with this historical contamination. The Company has completed remediation on this project, and accordingly, has ceased all related monitoring efforts.

•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.

•South Portland, Maine. Through its acquisition of Fairchild, the Company acquired a facility in South Portland, Maine. 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 Texas Instruments Incorporated. Although the Company may incur certain 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 CERCLA 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, 2021, the Company's Revolving Credit Facility included $15.0 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, 2021, which reduced the Company's borrowing capacity. The Company also had outstanding guarantees and letters of credit outside of its Revolving Credit Facility totaling $6.1 million as of December 31, 2021.

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, 2021. 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.

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.

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 regularly evaluates the status of the legal proceedings in which it is involved to assess whether a loss is probable or there is a reasonable possibility that a loss, or an additional loss, may have been incurred and determines if accruals are appropriate. If accruals are not appropriate, 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. Although litigation is inherently unpredictable, the Company believes that it has adequate provisions for any probable and estimable losses. Nevertheless, it is possible that the Company’s consolidated financial position, results of operations or liquidity could be materially and adversely affected in any particular period by the resolution of a legal proceeding. The Company’s estimates do not represent its maximum exposure. 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, 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.

Patent Litigation with Power Integrations, Inc. ("PI")

During 2019, the Company and PI entered into a Settlement Agreement (the "Settlement Agreement") pursuant to which the parties agreed to withdraw all outstanding legal and administrative disputes on the terms set forth in a binding term sheet previously entered into by and among the Company and PI on October 4, 2019.

Pursuant to the Settlement Agreement, the Company paid PI $175.0 million in cash during 2019, and the parties have dismissed all previously pending litigation and administrative proceedings. In addition, each party agreed to release the other party from any claims to damages or monetary relief for alleged acts of patent infringement across the various patent infringement litigation and not to file any additional action for legal or equitable relief until June 30, 2023. Neither party granted any licenses to the other.

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.

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.

As of December 31, 2021 and 2020, 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. The following table shows the adjustments to fair value of certain of the Company's non-financial assets that had an impact on the Company's results of operations (in millions):

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, 2021 and 2020, the Company had outstanding foreign exchange contracts with notional amounts of $288.3 million and $263.4 million, respectively. Such contracts were obtained through financial institutions and were scheduled to mature within one to three 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 losses and gains on the underlying assets, liabilities and transactions to which they are related.

Amounts receivable or payable under the contracts are included in other current assets or accrued expenses and other current liabilities in the accompanying Consolidated Balance Sheets. For the years ended December 31, 2021, 2020 and 2019, realized and unrealized foreign currency transactions totaled a loss of $0.8 million, $6.2 million and $5.0 million, 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

All derivatives are recognized on the balance sheet at their fair value and classified based on each instrument’s maturity date.

Foreign currency risk

The purpose of the Company's foreign currency hedging activities is to protect the Company from the risk that the eventual cash flows resulting from transactions in foreign currencies will be adversely affected by changes in exchange rates. During 2021, the Company entered into an insignificant forward contract that is designated as foreign currency cash flow hedge of forecasted payment denominated in a currency other than U.S. dollars. The Company did not have any outstanding derivatives for its foreign currency exposure designated as cash flow hedges as of December 31, 2020.

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, 2021.

Interest rate risk

The Company uses interest rate swap contracts to mitigate its exposure to interest rate fluctuations. As of December 31, 2021, the Company had interest rate swap agreements for notional amounts of $750.0 million, $500.0 million and $500.0 million for fiscal years 2022, 2023 and 2024, respectively. The Company did not identify any ineffectiveness with respect to the notional amounts of interest rate swap agreements outstanding as of December 31, 2021 and 2020.

Convertible Note Hedges

The Company entered into convertible note hedges in connection with the issuance of the 0% Notes and 1.625% Notes.

Other

At December 31, 2021, the Company had no outstanding commodity derivatives, currency swaps or options relating to either its debt instruments or investments. 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 counterparties to hedge contracts fail to perform their obligations. As of December 31, 2021, the counterparties to the Company's hedge contracts are held at financial institutions

_______________________

(1)On July 6, 2020, the Company completed a simplification of its corporate structure by repatriating the economic rights of its non-U.S. IP to the United States via domestication of certain foreign subsidiaries (the "Domestication"). The Domestication more closely aligns the Company's corporate structure with its operating structure in accordance with the OECD’s BEPS conclusions and changes to U.S. and European tax laws. The impact of the Domestication, which is regarded as a change in tax status, resulted in a benefit primarily from recognizing certain deferred tax assets, net of

deferred tax liabilities, of $63.0 million, or 35.7%.

(2)For the year ended December 31, 2021, this included a benefit of $26.3 million, or 2.2% related to a decrease in the valuation allowance for the expiration of Japan net operating losses ("NOLs"), partially netted with an offsetting expense of $22.6 million, or 1.9% related to the expiration of those same Japan NOLs. For the year ended December 31, 2020, this included a benefit of $49.4 million, or 28.0%, for the release of a partial state valuation allowance due to an increase to forecasted domestic income as a result of the Domestication of certain foreign subsidiaries and an expense of $61.8 million, or 35.0%, primarily related to the expiration of Japan NOLs, netted with the offsetting benefit of $61.8 million, or 35.0%, primarily for the decrease in the related valuation allowance for those same Japan NOLs. For the year ended December 31, 2019, this included an expense of $11.2 million, or 4.0%, primarily related to the write-off of Hong Kong NOL and expiration of Japan NOL, netted with the offsetting benefit of $11.2 million, or 4.0%, primarily for the decrease in related valuation allowance for those same Hong Kong and Japan NOLs.

(3)For the year ended December 31, 2021, this included an expense of $8.5 million, or 0.7%, related to an election to waive Base Erosion Anti-Abuse Tax ("BEAT") deductions for all U.S. federal tax purposes for the 2021 tax year.

The Company’s effective tax rate for 2021 was 12.7%, which differs from the U.S. federal income tax rate of 21%, primarily due to the benefit received from Section 250 deduction related to FDII.

The Company’s effective tax rate for 2020 was a benefit of (33.8)%, which differs from the U.S. federal income tax rate of 21%, primarily due to the Domestication of certain foreign subsidiaries and a partial release of state valuation allowance, partially offset by foreign taxes for which the Company will not receive a U.S. tax credit as well as period costs related to the Company's global intangible low-taxed income ("GILTI") inclusion.

The Company’s effective tax rate for 2019 was 22.7%, which differs from the U.S. federal income tax rate of 21%, primarily due to foreign taxes for which the Company will not receive a U.S. tax credit as well as period costs related to the Company's GILTI inclusion.

The FASB allows taxpayers to make an accounting policy election of either treating taxes due on GILTI inclusions as a current-period expense when incurred or recognizing deferred taxes for temporary basis differences that are expected to reverse as GILTI in future years. The company has made a policy choice to include taxes due on future GILTI inclusion as a current-period expense when incurred.

As of December 31, 2021 and 2020, the Company had approximately $77.5 million and $99.0 million, respectively, of U.S. federal NOL carryforwards, before the impact of unrecognized tax benefits. The decrease is primarily due to current year utilization, partially offset by NOLs acquired in the GTAT acquisition. A portion of these NOL carryforwards expire at various dates through 2037, if unutilized. NOLs generated after December 31, 2017 are carried forward indefinitely. As of December 31, 2021 and 2020, the Company had approximately $43.6 million and $153.4 million, respectively, of U.S. federal credit carryforwards, before the impact of unrecognized tax benefits. The decrease is primarily due to current year utilization. The credits will expire at various dates through 2041, if unutilized. These NOL carryforwards, and a portion of the credits, relate to acquisitions and, consequently, are limited in the amount that can be utilized in any one year as a result of the ownership change.

As of December 31, 2021 and 2020, the Company had approximately $491.1 million and $741.3 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, partially offset by NOLs acquired in the GTAT acquisition. The U.S. state NOL carryforwards will expire at various dates through 2040, if unutilized. As of December 31, 2021 and 2020, the Company had $138.4 million and $141.1 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 at various dates through 2035, if unutilized.

As of December 31, 2021 and 2020, the Company had approximately $551.8 million and $581.6 million, respectively, of foreign NOL carryforwards, before consideration of valuation allowance. The decrease is primarily due to the expiration of Japan NOLs. As of December 31, 2021 and 2020, the Company had $69.2 million and $69.4 million, respectively, of foreign credit carryforwards before consideration of valuation allowance or the impact of unrecognized tax benefits. A significant portion of the foreign NOLs and credit carryforwards will expire at various dates through 2025, if unutilized.

The Company continues to maintain a valuation allowance of $93.4 million on a portion of its Japan NOLs, which expire at various dates through 2024. In addition to the valuation allowance on the Japan NOLs, the Company maintains a full valuation allowance on NOLs in Hong Kong of $25.5 million. The Company also maintains a partial valuation allowance of $69.7 million on its U.S. state deferred tax assets, primarily NOLs and credits. The remaining valuation allowance relates to NOLs and tax credits in certain other foreign jurisdictions that primarily expire in 2025.

At December 31, 2021, 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 Company maintains liabilities for unrecognized tax benefits. These liabilities involve considerable judgment and estimation and are continuously monitored by management based on the best information available, including changes in tax regulations, the outcome of relevant court cases, and other information. The Company is currently under examination by various taxing authorities. Although the outcome of any tax audit is uncertain, the Company believes that it has adequately provided in its consolidated financial statements for any additional taxes that the Company may be required to pay as a result of such examinations. If the payment ultimately proves not to be necessary, the reversal of these tax liabilities would result in tax benefits being recognized in the period the Company determines such liabilities are no longer necessary. However, if an ultimate tax assessment exceeds the Company's estimate of tax liabilities, additional tax expense will be recorded. The impact of such adjustments could have a material impact on the Company's results of operations in future periods.

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

	2021		2020		2019
Balance at beginning of year	$	151.0	$	130.0	$	112.2
Acquired balances	9.3		—		15.5
Additions for tax benefits related to the current year	3.1		11.9		9.4
Additions for tax benefits of prior years	—		12.3		8.0
Reductions for tax benefits of prior years	(19.7)		(1.4)		(0.2)
Lapse of statute	(2.7)		(1.3)		(8.2)
Settlements	(3.8)		(0.5)		(6.7)
Balance at end of year	$	137.2	$	151.0	$	130.0

Included in the December 31, 2021 balance of $137.2 million is $92.5 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, 2021 is $44.7 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 $64.2 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 in relation to unrecognized tax benefits in tax expense. The Company recognized approximately $3.3 million of net tax benefit and $0.2 million of tax expense for interest and penalties during the year ended December 31, 2021 and 2020, respectively. The Company did not recognize any additional tax benefit or expense for interest and penalties during the year ended December 31, 2019. The Company had approximately $1.3 million, $5.3 million, and $5.1 million of accrued interest and penalties at December 31, 2021, 2020, and 2019, respectively.

The Company is currently under IRS examination for the 2017 tax year. Tax years prior to 2017 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 2017. The Company is also subject to routine examinations by various foreign tax jurisdictions in which it operates. With respect to jurisdictions outside the United States, the Company is generally not subject to examination for tax years prior to 2011. The Company believes that adequate provisions have been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with the Company's expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs.
