PART I

Overview

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

We provide intelligent power and intelligent sensing solutions with a primary focus towards automotive and industrial markets to help our customers solve challenging problems and create cutting-edge products for a better future. 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 power solutions for the automotive industry allow our customers to exceed range targets with lower weight and reduce system cost through efficiency. Our intelligent sensing technologies support the next generation industry, allowing for smarter factories and buildings while also enhancing the automotive mobility experience with imaging and depth sensing that make advanced vehicle safety and automated driving systems possible.

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

As of December 31, 2023, 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 profitable revenue and operating income growth by capturing high-growth megatrends in our focused end-markets of automotive and industrial infrastructure. We are designing products in highly-differentiated markets focused on customer needs while optimizing our manufacturing footprint to support growth and maintain gross margins through efficiencies and new product development.

We are focused on achieving efficiencies in our operating and capital expenditures, capital allocation on research and development investments and resources to accelerate growth in high-margin products and end-markets. During the year, we ramped up manufacturing at our EFK location, as well as expanded our capacity in Hudson, New Hampshire, Roznov, the Czech Republic, and Bucheon, South Korea to increase our SiC manufacturing capabilities to meet the growing demand for our SiC-based solutions.

Business Realignment

During 2023, we realigned our operating models in ASG, Corporate information technology ("IT") organization and certain manufacturing locations in order to streamline our operations, achieve organizational efficiencies and consolidate resources into fewer, common sites across the world to align with the next phase of our multi-year "Fab Right" manufacturing strategy. Under these business realignment efforts, approximately 1,900 employees were notified of their employment termination. We incurred severance and related charges of approximately $59.1 million related to these actions in 2023.

2023 Financing activities

0.50% Convertible Senior Notes due 2029

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

New Credit Agreement

On June 22, 2023, we entered into the New Credit Agreement to replace the Revolver due 2024, which was maturing on June 28, 2024. We drew $375.0 million against the Revolving Credit Facility and repaid the entire outstanding balance under the Revolver due 2024. We had previously repaid $125.0 million of the outstanding balance under the Revolver due 2024 during the first quarter of 2023. As of December 31, 2023, we had approximately $1.1 billion available under the Revolving Credit Facility for future borrowings.

1.625% Notes maturity and repayment

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

See Note 7: ''Restructuring, Asset Impairments and Other Charges, net'' 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 related to our restructuring efforts and financing activities.

Acquisitions and Divestitures during 2021 and 2022

On October 28, 2021, we completed our acquisition of GT Advanced Technologies Inc. ("GTAT"), a producer of SiC substrates. 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 $10.0 million, in exchange for all of the outstanding equity interests of GTAT.

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

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

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

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.

The following table illustrates the product technologies under each of our segments based on our operating strategy:

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.

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 2023, we continued to enter into long-term supply agreements with certain strategic end-customers, which generally include minimum purchase commitments or amended existing terms based on mutual agreements. Certain of our agreements, subject to our standard terms and conditions, have provisions allowing for renegotiation upon mutual agreement.

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 52% of our revenue in 2023, 58% of our revenue in 2022 and 64% of our revenue in 2021. There were no distributors whose revenue exceeded 10% or more of total revenue for the year ended December 31, 2023. We had one distributor whose revenue accounted for approximately 12% and 13% of the total revenue for the years ended December 31, 2022 and 2021, respectively. Our distributors resell our products to OEMs, contract

manufacturers, and other end-customers. 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, accounted for approximately 48% of our revenue in 2023, 42% of our revenue in 2022 and 36% of our revenue in 2021. 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'' under the heading "Revenue Recognition" in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K.

Markets

Product Development

onsemi is focused on innovation to create intelligent power and sensing technologies that solve the most challenging customer problems. Our product development efforts are directed towards the following:

• powering the electrification of the automotive industry with our intelligent power technologies that allow for lighter and longer-range electric vehicles and enable efficient fast-charging systems;

Other includes the end-markets of computing, consumer, networking, communication, etc.

Competition

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

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

PSG

Our competitive strengths include our core competencies of leading-edge fabrication technologies, micro and module packaging expertise, breadth of product line and IP portfolio, high-quality, cost-effective manufacturing and supply chain management, which helps to ensure 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 intelligent power technologies based on silicon and SiC wide band gap technologies, which we use to design, manufacture, and deliver to our customers as bare die, packaged discrete solutions or power module solutions. In addition to our power technologies, we believe our integrated circuit, signal and protection technologies have significant performance advantages over our competition. PSG’s primary competitors include: Infineon Technologies AG ("Infineon"), STMicroelectronics N.V. ("STMicroelectronics"), Wolfspeed Inc., Texas Instruments Incorporated ("TI") and Nexperia BV.

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 yields and availability of supply, customer service, pricing, industry trends and general economic trends. Competitors for

certain of ASG's products and solutions include: TI, Analog Devices, Inc., Infineon, STMicroelectronics, Renesas Electronics Corporation, Monolithic Power Systems Inc. and NXP Semiconductors N.V. ("NXP").

All of our manufacturing facilities are fully owned and operated by us, except our assembly and test operations facility located in Leshan, China, which is owned by Leshan-Phoenix Semiconductor Company Limited, a joint venture company in which we own 80% of the outstanding equity interests ("Leshan"). The financial and operating results of Leshan have been consolidated in our financial statements. Our joint venture partner is Leshan Radio Company Ltd. ("Leshan Radio"), formerly a Chinese state-owned enterprise. Pursuant to the joint venture agreement between us and Leshan Radio, requests for production capacity are made to the board of directors of Leshan by each shareholder of the joint venture. Each request represents a purchase commitment, provided that any shareholder may elect to pay the cost associated with the unused capacity (which is generally equal to the fixed cost of the capacity) in lieu of satisfying the commitment. We purchased 80% of Leshan's production capacity in each of 2023, 2022 and 2021, and are currently committed to purchase approximately 80% of Leshan's expected production capacity in 2024.

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 36% of our total manufacturing input costs in 2023, 43% in 2022 and 37% in 2021.

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

Turnover

We monitor employee turnover rates by region and globally. The average tenure of our employees is approximately 10 years and approximately 40% 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.

Trends, Risks and Uncertainties Related to Our Business

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

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

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

Our manufacturing efficiency is contingent upon the operations of these interdependent processes and will continue to be an important factor in our future profitability, and there can be no assurance that we will be able to maintain this manufacturing efficiency, increase manufacturing efficiency to the same extent as our competitors, or be successful in our manufacturing rationalization plans. For example, public health crises like the COVID-19 pandemic and related adverse public health developments may cause disruption to our domestic and international operations. Any associated worker absenteeism, quarantines and restrictions on certain of our employees’ ability to perform their jobs, office and factory closures or restrictions, labor shortages, disruptions to ports and other shipping infrastructure, border closures and/or other travel or health-related restrictions could, depending on the magnitude of such effects on our manufacturing activities (or activities of our suppliers, third-party distributors or sub-contractors), could cause disruption and delay to our supply chain, manufacturing and product shipments. Such disruption and delays could materially adversely affect our business, results of operations and financial condition.

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

if customers reduce, delay or cancel orders, we may incur excess or obsolete inventory

Risk Management and Strategy

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

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

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

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

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

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

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

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

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

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

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

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

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

As of December 31, 2023, we have not identified any risks from cybersecurity threats (including any previous cybersecurity incidents) that have materially affected the Company, our business strategy, our results of operations or our financial condition. For a discussion of risks from cybersecurity threats that could be reasonably likely to materially affect us, please see our Risk Factors discussion under the heading, “Trends, Risks and Uncertainties Related to Technology and Data Privacy” in this Form 10-K.

Governance

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

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

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

Our ECS team is led by our CISO. Our CISO reports to our CIO who, in turn, reports to our Executive Vice President and Chief Financial Officer. Our CISO has 24 years of experience in leading global security functions and strategies. Collectively, the other members of our ECS team have decades of relevant education and experience and maintain a wide range of industry certifications. We invest in regular, ongoing cybersecurity training for our ECS team.

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

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

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

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

legal proceedings and related matters.

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, 2023 was $8,253.0 million, representing a nominal decrease of 0.9% from $8,326.2 million for the year ended December 31, 2022. During 2023, we reported net income attributable to onsemi of $2,183.7 million compared to $1,902.2 million in 2022. Our operating income totaled $2,538.7 million during 2023 compared to $2,360.0 million during 2022. The increases in our operating income and net income were primarily due to goodwill and intangible asset impairment charges related to our QCS wind down in 2022 amounting to $386.8 million, which did not reoccur in 2023. Our gross margin decreased by approximately 190 basis points to 47.1% in 2023 from 49.0% in 2022. See discussion under "Results of Operations" for the reasons for the fluctuations year over year.

Business and Macroeconomic Environment

The semiconductor industry has traditionally been highly cyclical, has often experienced significant downturns in connection with, or in anticipation of, declines in general economic conditions, and may experience uncertainty and volatility in the future.

During 2023, the semiconductor industry experienced a slow down due to softening demand. We are monitoring the economic environment and related forecasts, and for indicators that would suggest the global economic slowdown could continue. Given the current conditions, we are actively managing and have taken corrective actions in our manufacturing capacity and spending to align with the forecasted 2024 demand. We believe the current volatility in general economic conditions is not expected to have a significant impact on our long-term strategic and growth initiatives.

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

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

Results of Operations

A discussion of our results of operations for the year ended December 31, 2023 compared to December 31, 2022 is included below. For a discussion and comparison of the results of our operations for the year ended December 31, 2022 with the year ended December 31, 2021, refer to "Management's Discussion and Analysis of Financial Conditions and Results of Operations" in our Form 10-K for the year ended December 31, 2022 filed with the SEC on February 6, 2023.

Operating Results

The following table summarizes certain information relating to our operating results that has been derived from our audited consolidated financial statements (in millions):

Revenue

Revenue was $8,253.0 million and $8,326.2 million for 2023 and 2022, respectively. The decrease from 2022 to 2023 of $73.2 million, or 0.9%, was attributable to a 12.4% decrease in revenue in ASG, partially offset by a 5.7% and 3.0% increase in revenue in PSG and ISG, respectively, which are further explained below. There were no customers whose revenue exceeded 10% or more of total revenue for the year ended December 31, 2023.

Revenue by operating and reportable segments was as follows (dollars in millions):

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

Revenue from PSG

Revenue from PSG increased by $240.8 million, or approximately 5.7%, during 2023 compared to 2022. The revenue from our Advanced Power Division increased by $527.9 million, offset by a decrease of $287.1 million in our Integrated Circuits, Protection and Signal Division. This increase was primarily driven by our continued ramp up in SiC and other power automotive solutions, while the decrease was primarily driven by planned customer product exits and reduced demand driven by lower end-market requirements for these products.

Revenue from ASG

Revenue from ASG decreased by $352.8 million, or approximately 12.4%, during 2023 compared to 2022, due to a decrease in revenue from our Power Management Division of $354.7 million, primarily driven by the planned end of life for targeted products as well as a general decline in demand in the computing and consumer end-markets.

Revenue from ISG

Revenue from ISG increased by $38.8 million, or approximately 3.0%, during 2023 compared to 2022, which was largely driven by an increase in revenue from our Automotive Sensing Division of $117.4 million primarily due to the reallocation of internal capacity to products yielding higher average selling prices. This was partially offset by a decrease of $78.7 million in our Industrial and Consumer Solutions Division due to capacity reallocation and planned product exits.

Revenue by Geographic Location

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

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

Gross Profit and Gross Margin

Gross profit was $3,883.5 million and $4,077.2 million for 2023 and 2022, respectively, representing a decrease of $193.7 million or approximately 5%.

For the overall Company, the decline in existing product revenue negatively impacted gross profit by approximately $400 million, and higher manufacturing costs at our EFK location, which include start up and ramp up costs, along with an unfavorable impact from our foundry business, negatively impacted gross profit by approximately $160 million. This decrease was partially offset by the gross profit of approximately $320 million from new product sales.

Our gross margin decreased by 1.9% from 49.0% for the year ended December 31, 2022 to 47.1% for the year ended December 31, 2023, due to the impact of the factors explained above.

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

PSG gross profit and gross margin increased by $117 million and 0.1%, respectively, primarily driven by increased revenue from new product sales, which contributed approximately $320 million, and was partially offset by the impact of the decrease in revenue from existing products amounting to approximately $180 million.

ASG gross profit and gross margin decreased by $342.6 million and 6.4%, respectively, primarily driven by the decline in existing product revenue which impacted gross profit by approximately $250 million, as well as the higher manufacturing costs at our EFK location, which includes the unfavorable impact of our foundry business of approximately $120 million.

ISG gross profit and gross margin increased by $31.9 million and 1%, respectively, primarily driven by increased revenue in existing products due to favorable pricing and product mix.

Operating Expenses

Research and Development

Research and development expenses were $577.3 million and $600.2 million, or approximately 7% and 7% of revenue for 2023 and 2022, respectively, representing a decrease of $22.9 million, or approximately 4% year-over-year. The decrease was primarily due to a reduction in variable compensation expense, partially offset by an increase in new product development costs.

Selling and Marketing

Selling and marketing expenses were $279.1 million and $287.9 million, or approximately 3% and 3% of revenue for 2023 and 2022, respectively, representing a decrease of $8.8 million, or approximately 3% year-over-year, primarily due to a reduction in variable compensation expense.

General and Administrative

General and administrative expenses were $362.4 million and $343.2 million, or approximately 4% and 4% of revenue for 2023 and 2022, respectively, representing an increase of $19.2 million, or approximately 6% year-over-year. The increase was primarily due to expenses associated with information technology initiatives and a bad debt provision on outstanding receivable balances generated under an agreement with a business partner, which was partially offset by a decrease in variable compensation expense.

Amortization of Acquisition-Related Intangible Assets

Amortization of acquisition-related intangible assets was $51.1 million and $81.2 million for 2023 and 2022, respectively, representing a decrease of $30.1 million, or approximately 37.1%, year-over-year. The decrease was due to the impairment of intangible assets associated with the QCS wind down during 2022, and a reduction in amortization expense as certain intangible assets became fully amortized.

Restructuring, Asset Impairments and Other Charges, net

Restructuring, asset impairments and other charges, net was $74.9 million and $17.9 million for 2023 and 2022, respectively,

representing an increase of $57.0 million. Charges in 2023 related primarily to the business realignment efforts during 2023. For additional information, see Note 7: ''Restructuring, Asset Impairments and Other Charges, net'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K.

Goodwill and Intangible Asset Impairment

Goodwill and intangible asset impairment charges were zero and $386.8 million for 2023 and 2022, respectively. During 2022, we recorded goodwill impairment charges of $330.0 million and intangible asset impairment charges of $56.8 million related to the QCS wind down. See Note 6: ''Goodwill and Intangible Assets'' in the notes to our unaudited consolidated financial statements included elsewhere in this Form 10-K for additional information.

Other Income and Expenses

Interest Expense

Interest expense decreased by $20.1 million, or approximately 21.2%, to $74.8 million during 2023 compared to $94.9 million in 2022. The decrease was primarily due to the repayment of the balance under the Term Loan "B" Facility, which was repaid with proceeds from the 0.50% Notes. Additionally, the 1.625% Notes matured and were repaid during October 2023. Our average gross amount of long-term debt balance (including current maturities) during 2023 and 2022 was $3,304.1 million and $3,243.3 million, respectively. Our weighted average interest rate on our gross amount of long-term debt (including current maturities) was 2.3% and 2.9% per annum in 2023 and 2022, respectively.

Interest income

Interest income increased by $77.6 million, or approximately 500.6%, to $93.1 million during 2023 compared to $15.5 million in 2022, primarily due to the increase in interest rates during 2023 along with a strategic shift in our investment strategy.

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 (loss) on divestiture of businesses

Loss on divestiture of business was $0.7 million in 2023, compared to a gain of $67.0 million in 2022. During 2022, we divested the wafer manufacturing facilities in Niigata, Japan, Pocatello, Idaho, South Portland, Maine and Oudenaarde, Belgium and recognized the gain relating to such divestitures.

Loss on Debt Refinancing and Prepayment

We recorded loss on debt refinancing and prepayment of $13.3 million during 2023 compared to $7.1 million during 2022. The 2023 loss was due to the write-off relating to the repayment of the Term Loan "B" Facility, and the 2022 loss was primarily related to the partial prepayment of the Term "B" Facility. 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.

Other income (expense), net

Other income (expense), net was an expense of $7.2 million in 2023, compared to an income of $21.7 million in 2022. During 2023 we recognized actuarial losses on pension plans of $4.0 million, whereas we recognized actuarial gains on pension plans of $22.1 million during 2022.

Income Tax Provision

We recorded an income tax provision of $350.2 million and $458.4 million in 2023 and 2022, respectively, representing effective tax rates of 13.8% and 19.4%. The decrease in our effective tax rate was due to the goodwill impairments in the prior year, which were not deductible for tax purposes, and a current year benefit due to the net release of unrecognized tax benefits.

For additional information, see Note 16: ''Income Taxes'' and Note 6: ''Goodwill and Intangible Assets'' in the notes to the audited consolidated financial statements included elsewhere in this Form 10-K.

Liquidity and Capital Resources

Overview

Our principal sources of liquidity are cash on hand, cash generated from operations, available borrowings under our Revolving Credit Facility as well as new debt and/or equity issuances. In the near term, we expect to fund our cash requirements by utilizing any or a combination of these principal sources, including any amounts required to satisfy our current portion of long-term debt. Our cash and cash equivalents were $2,483.0 million as of December 31, 2023 and our Revolving Credit Facility has approximately $1.1 billion available for future borrowings as of December 31, 2023.

We require cash to: (i) fund our operating expenses, working capital requirements, outlays for strategic acquisitions and investments; (ii) service our debt, including principal and interest; (iii) incur capital expenditures; and (iv) repurchase our common stock.

During the ordinary course of business, we evaluate our cash requirements and, if necessary, adjust our expenditures to reflect the current market conditions and our projected sales and demand. Our capital expenditures are primarily directed towards manufacturing equipment and can materially influence our available cash for other initiatives. Future capital expenditures may be impacted by events and transactions that are not currently forecasted.

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

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

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

Sources and Uses of Cash

The following are the significant sources and uses of cash during 2023:

• Cash flows from operating activities of $1,977.5 million.

• Purchase of property, plant & equipment of $1,575.6 million.

• Issuance of $1.5 billion of 0.50% Notes, the net proceeds of which were used to repay the existing indebtedness under the Term Loan "B" Facility, net cost of the related convertible note hedges, the related transaction fees and general corporate purposes.

• Repayment of $125 million under the Revolver due 2024 in the first quarter of 2023.

• Entering into the New Credit Agreement consisting of a $1.5 billion Revolving Credit Facility and draw down of $375 million to repay the entire outstanding balance under the Revolver due 2024 in the second quarter of 2023.

• Repurchases of approximately 7.6 million shares of common stock for an aggregate purchase price of $564.0 million under the Share Repurchase Program.

• Repayment of the 1.625% Notes amounting to $119.6 million in cash upon maturity and issuance of approximately 4.5 million shares of common stock to settle the excess over the principal.

Operating Activities

Our long-term cash generation is dependent on the ability of our operations to generate cash. Our cash flows from operating activities were $1,977.5 million, $2,633.1 million and $1,782.0 million for the years ended December 31, 2023, 2022 and 2021,

respectively. Our operating cash flows for the year ended December 31, 2023 decreased by $655.6 million, or 24.9%, compared to the year ended December 31, 2022 and was primarily attributable to increased working capital requirements related to our strategic investments in SiC inventory and our strategic investments in inventory for fab transitions, and payments related to the 2022 variable compensation.

Our ability to maintain positive operating cash flows is dependent on, among other factors, our success in achieving our revenue goals and in meeting LTSA commitments 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.

Investing Activities

Our cash flows used in investing activities were $1,737.9 million, $705.4 million and $915.1 million for the years ended December 31, 2023, 2022 and 2021, respectively. The increase of $1,032.5 million for the year ended December 31, 2023 compared to the year ended December 31, 2022 was primarily attributable to an increase in capital expenditures, the absence of any divestiture activities in 2023 and the remaining payment of $236.3 million related to the acquisition of our EFK location. During the years ended December 31, 2023, 2022 and 2021, we paid $1,575.6 million, $1,005.0 million and $444.6 million, respectively, for capital expenditures. Our capital expenditures as a percent of revenue increased in 2023 to 19%, primarily as a result of investments to expand SiC manufacturing capacity. In 2024, we expect capital expenditures to be in the range of 10% - 12% of revenue as these investments along with other capital initiatives are expected to decrease.

Financing Activities

Our cash flows used in financing activities were $686.5 million, $370.0 million and $569.4 million for the years ended December 31, 2023, 2022 and 2021, respectively. The increase of $316.5 million for the year ended December 31, 2023 compared to the year ended December 31, 2022 was primarily attributable to proceeds and payments related to long-term borrowings and share repurchase activity. During 2023, we replaced the Revolver due 2024 maturing on June 28, 2024 with the Revolving Credit Facility. We do not have any meaningful debt maturing during the next 12 months. Our 0% Notes are classified as a current liability based on share price trigger provisions. We expect to continue repurchases under our Share Repurchase Program subject to market conditions, the price of our shares and other factors (including liquidity needs). However, the Share Repurchase Program may be modified, suspended or terminated by the Board of Directors at any time without prior notice.

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

Debt

As of December 31, 2023, we were in compliance with the indentures relating to our 0% Notes, 0.50% Notes and 3.875% Notes and with the financial covenants included in the New Credit Agreement. The 0% Notes, 0.50% Notes and 3.875% Notes are senior to the existing and future subordinated indebtedness of onsemi and its guarantor subsidiaries, rank equally in right of payment to all of our existing and future senior debt and, as unsecured obligations, are subordinated to all of our existing and future secured debt to the extent of the assets securing such debt. Failure to comply with any of our covenants or any other terms of our New Credit Agreement could result in higher interest rates in our borrowings or the acceleration of the maturities of our outstanding debt. In order to remain in compliance with the various financial covenants contained in our debt agreements and to fund working capital, our capital expenditures and business development efforts will depend on our ability to generate cash from operating activities, which is subject to, among other things, our future operating performance, as well as financial, competitive, legislative, regulatory and other conditions, some of which may be beyond our control.

As of December 31, 2023, there was $804.9 million aggregate principal amount of the 0% Notes, $1,500.0 million aggregate principal amount of the 0.50% Notes and $700.0 million aggregate principal amount of 3.875% Notes. The aggregate principal amount of outstanding 0% Notes, net of unamortized discount and issuance costs, has been reclassified as a current portion of long-term debt based on the share price trigger provisions. The associated interest expense related to our 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.

Key Financing and Capital Events

Overview

We continually evaluate our debt and capital structure and when appropriate, we have completed various measures to secure liquidity, repurchase shares of our common stock, reduce interest costs, amend or replace existing key financing arrangements and, in some cases, extend a portion of our debt maturities to continue to provide us additional operating flexibility. We took certain of these actions in 2023, which included the issuance of $1.5 billion of 0.50% Convertible Senior Notes to repay our Term Loan "B" facility and the termination and replacement of the Prior Credit Agreement with the New Credit Agreement. See Note 9: ''Long-Term Debt'' and for further discussion on the Share Repurchase Program, see Note 10: ''Earnings Per Share and Equity'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K.

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

Critical Accounting Policies and Estimates

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

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

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

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

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

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, 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.

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 and Other Developments'' in the notes to our audited consolidated financial statements included elsewhere in this Form 10-K.

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, 2023, our gross long-term debt (including current maturities) totaled $3,379.9 million. We have no interest rate exposure to rate changes on our fixed rate debt, which totaled $3,004.9 million. We do have interest rate exposure with respect to our Revolving Credit Facility, which had a $375.0 million balance as of December 31, 2023. We estimate a 50 basis point increase in interest rates would impact our expected annual interest expense for the next 12 months by approximately $1.9 million. However, this impact may be partially offset by the additional interest earned on our cash and cash equivalents.

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

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

We enter into forward foreign currency contracts that economically hedge the gains and losses generated by the re-measurement of certain recorded assets and liabilities in a non-functional currency. Changes in the fair value of these undesignated hedges are recognized in other income and expense immediately as an offset to the changes in the fair value of the assets or liabilities being hedged. The notional amount of foreign exchange contracts at December 31, 2023 and 2022 was $262.2 million and $272.0 million, respectively.

Substantially all of our revenue is transacted in U.S. Dollars. However, a significant amount of our operating expenditures and capital purchases are transacted in local currencies, including Chinese Renminbi, Czech Koruna, Euros, Japanese Yen, Korean Won, Malaysian Ringgit, Philippine Peso and Vietnamese Dong. Due to the materiality of our transactions in these local currencies, our results are impacted by changes in currency exchange rates measured against the U.S. Dollar. For example, we determined that based on a hypothetical weighted-average change of 10% in currency exchange rates, our operating income would have impacted our income before taxes by approximately $125.8 million for the year ended December 31, 2023, 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.

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.

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, 2023.

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, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management's Report on Internal Control Over Financial Reporting.

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

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2023. 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, 2023.

The effectiveness of our internal control over financial reporting as of December 31, 2023 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.

Insider Trading Arrangements
