RISK FACTORS

Summary of Risk Factors

Risks Related to the Semiconductor Industry which Impact Us

•We, and the semiconductor industry as a whole, may be impacted by changes in, or uncertainty about, global, regional and local economic, political, legal, regulatory and social environments as well as climate change

•The semiconductor industry is cyclical and downturns in the semiconductor industry can negatively affect our results of operations and financial condition

•Epidemics or pandemics may impact the global economy and could also adversely affect our business, financial condition and results of operations

•We may not be able to match our production capacity to demand

•Competition in the semiconductor industry is intense, and we may not be able to compete successfully if our product design technologies, process technologies and products do not meet market requirements. Furthermore, the competitive environment of the industry has resulted, and is expected to continue to result, in vertical and horizontal consolidation among our suppliers, competitors and customers, which may lead to erosion of our market share, impact our ability to compete and require us to restructure our operations

Risks Related to Our Operations

•Our high fixed costs could adversely impact our results

•Our capital needs are high compared to those competitors who do not manufacture their own products and we may need additional funding in the coming years to finance our investments, to purchase other companies or technologies developed by third parties or to refinance our maturing indebtedness

•Our operating results depend on our ability to obtain quality supplies on commercially reasonable terms. As we depend on a limited number of suppliers for materials, equipment and technology, we may experience supply disruptions if suppliers interrupt supply, increase prices or experience material adverse changes in their financial condition.

•Our financial results can be affected by fluctuations in exchange rates, principally in the value of the U.S. dollar.

•Our operating results may vary significantly from quarter to quarter and annually and may also differ significantly from our expectations or guidance

•If our external silicon foundries or back-end subcontractors fail to perform, this could adversely affect our business prospects, financial condition and results of operations

•Our manufacturing processes are highly complex, costly and potentially vulnerable to impurities, disruptions or inefficient implementation of production changes or interruptions that can significantly increase our costs and delay product shipments to our customers

•We may experience quality problems from time to time that can result in decreased sales and operating margin and product liability or warranty claims

•Disruptions in our relationships with any one of our key customers or distributors, and/or material changes in their strategy or financial condition or business prospects, could adversely affect our results of operations

•We may experience delays in delivering our product and technology roadmaps as well as transformation initiatives

9

•Our computer systems, including hardware, software, information and cloud-based initiatives, are subject to attempted security breaches and other cybersecurity threats, which, if successful, could adversely impact our business

•We may be subject to theft, loss, or misuse of personal data about our employees, customers, or other third parties, which could increase our expenses, damage our reputation, or result in legal or regulatory proceedings

•Our business is dependent in large part on continued growth in the industries and segments into which our products are sold and on our ability to retain existing customers and attract new ones. A market decline in any of these industries, our inability to retain and attract customers, or customer demand for our products which differs from our projections, could have a material adverse effect on our results of operations

•Market dynamics have driven, and continue to drive us, to a strategic repositioning

•We depend on collaboration with other semiconductor industry companies, research organizations, universities, customers and suppliers to further our R&D efforts, and our business and prospects could be materially adversely affected by the failure or termination of such alliances

•We depend on patents to protect our rights to our technology and may face claims of infringing the IP rights of others

•We operate in many jurisdictions with highly complex and varied tax regimes. Changes in tax rules, new or revised legislation or the outcome of tax assessments and audits could cause a material adverse effect on our results

•We receive public funding, and a reduction in the amount available to us or demands for repayment could increase our costs and impact our results of operations

•Some of our production processes and materials are environmentally sensitive, which could expose us to liability and increase our costs due to environmental, health and safety laws and regulations or because of damage to the environment

•Climate change and related sustainability regulations and initiatives, including our commitment to become carbon neutral by 2027 on scope 1 and 2 and partially scope 3, could place additional burden on us and our operations

•Loss of key employees and the inability to continuously recruit and retain qualified employees could hurt our competitive position

•The interests of our controlling shareholder, which is in turn indirectly controlled by the French and Italian governments, may conflict with other investors’ interests. In addition, our controlling shareholder may sell our existing common shares or issue financial instruments exchangeable into our common shares at any time

•Our shareholder structure and our preference shares may deter a change of control

•Any decision to reduce or discontinue paying cash dividends to our shareholders could adversely impact the market price of our common shares

•We are required to prepare financial statements under IFRS and we also prepare Consolidated Financial Statements under U.S. GAAP, and such dual reporting may impair the clarity of our financial reporting

•There are inherent limitations on the effectiveness of our controls

•Because we are subject to the corporate law of The Netherlands, U.S. investors might have more difficulty protecting their interests in a court of law or otherwise than if we were a U.S. company

Risks Related to the Semiconductor Industry which Impact Us

We, and the semiconductor industry as a whole, may be impacted by changes in, or uncertainty about, global, regional and local economic, political, legal, regulatory and social environments as well as climate change.

Changes in, and uncertainty about, economic, political, legal, regulatory and social conditions pose a risk as consumers and businesses may postpone spending in response to factors such as curtailment of trade and other business restrictions, financial market volatility, interest rate fluctuations, recessions, shifts in inflationary and deflationary expectations, lower capital and productivity growth, unemployment, negative news, declines in income or asset values and/or other factors. Such global, regional and local conditions could have a material adverse effect on customer and end-market demand for our products, thus materially adversely affecting our business and financial condition.

Geopolitical conflicts have resulted in certain countries imposing sanctions. Further consequences of such conflicts could include a risk of further sanctions, embargoes, regional instability, geopolitical shifts and adverse effects on macro-economic conditions, currency exchange rates and financial markets. This could lead to disruption to international commerce and the global economy, and could have a negative effect on our ability to sell to, ship products to, collect payments from, and support customers in certain regions based on trade restrictions, embargoes, logistics restrictions and export control law restrictions. We may also experience a shortage of certain semiconductor components and delays in shipments due to supply chain disruptions caused by geopolitical conflicts, and sales of our products may be negatively impacted by geopolitical conflicts, both directly and indirectly through a reduction of sales or production by our customers in or to affected areas or otherwise.

The institution of trade tariffs globally, as well as the threat thereof, could negatively impact economic conditions, which could have negative repercussions for our business. In particular, trade protection and national security policies of the U.S. and Chinese governments, including tariffs, trade restrictions, export restrictions and the placing of companies on restricted entity lists, have and may continue to limit or prevent us from transacting business with certain of our Chinese customers or suppliers; limit, prevent or discourage certain of our Chinese customers or suppliers from transacting business with us; or make it more expensive to do so. If disputes were to arise under any of our agreements with other parties conducting business in China, the resolution of such dispute may be subject to the exercise of discretion by the Chinese government, or agencies of the Chinese government, which may have a material adverse effect on our business. In addition, we could face increased competition as a result of China's programs to promote a domestic semiconductor industry and supply chains (including the Made in China 2025 campaign).

Trade policy changes could trigger retaliatory actions by affected countries, which could have a negative impact on our ability to do business in affected countries or lead to reduced purchases of our products by foreign customers, leading to increased costs of components contained in our products, increased manufacturing costs of our products, currency exchange rate volatility, and higher prices for our products in foreign markets. Further, protectionist measures, laws or governmental policies may encourage our customers to relocate their manufacturing capacity or supply chain to their own respective countries or other countries, or require their respective contractors, subcontractors and relevant agents to do so, which could impair our ability to sustain our current level of productivity and manufacturing efficiency.

We, and the semiconductor industry as a whole, face greater risks due to the international nature of the semiconductor business, including in the countries where we, our customers or our suppliers operate, such as:

•instability of foreign governments, including the threat of war, military conflict, civil unrest, regime changes, mass migration and terrorist attacks;

•natural events such as severe weather, earthquakes and tsunamis, or the effects of climate change;

•epidemics or pandemics such as disease outbreaks and other health related issues;

11

•changes in, or uncertainty about, laws, regulations (including executive orders) and policies affecting trade and investment, including following Brexit and including through the imposition of trade and travel restrictions, government sanctions, local practices which favor local companies and constraints on investment;

•complex and varying government regulations and legal standards, particularly with respect to export control regulations and restrictions, customs and tax requirements, data privacy, IP and anti-corruption;

•differing practices of regulatory, tax, judicial and administrative bodies, including with regards to the interpretation of laws, governmental approvals, permits and licenses;

•water availability, usage and consumption levels, as well as recycling and discharge practices; and

•labor and human rights, especially in international supply chains.

The semiconductor industry is cyclical and downturns in the semiconductor industry can negatively affect our results of operations and financial condition.

The semiconductor industry is cyclical and has been subject to significant downturns from time to time, as a result of global economic conditions, as well as industry-specific factors, such as built-in excess capacity, fluctuations in product supply, product obsolescence and changes in end-customer preferences. See “Item 3. Key Information — Risk Factors — Risks Related to the Semiconductor Industry which Impact Us — We, and the semiconductor industry as a whole, may be impacted by changes in, or uncertainty about, global, regional and local economic, political, legal, regulatory and social environments as well as climate change.”

Downturns are typically characterized by reduction in overall demand, accelerated erosion of selling prices, reduced revenues and high inventory levels, any of which could result in a significant deterioration of our results of operations. Such macro-economic trends typically relate to the semiconductor industry as a whole rather than to the individual semiconductor markets to which we sell our products. To the extent that industry downturns are concurrent with the timing of new increases in production capacity or introduction of new advanced technologies in our industry, the negative effects on our business from such industry downturns may also be more severe. We have experienced revenue volatility and market downturns in the past and expect to experience them in the future, which could have a material adverse impact on our results of operations and financial condition.

The recent increase in inflation rates in the markets in which we operate may lead us to experience higher costs related to labor, energy, water, transportation, wafer and other raw materials costs from suppliers. Our suppliers may raise their prices, and in the competitive markets in which we operate, we may not be able to make corresponding price increases to preserve our gross margins and profitability due to market conditions and competitive dynamics. Additionally, any such increase in prices may not be accepted by our customers.

Epidemics or pandemics may impact the global economy and could also adversely affect our business, financial condition and results of operations.

Epidemics or pandemics may result in authorities imposing, and businesses and individuals implementing, numerous measures to try to contain the virus, including travel bans and restrictions, shelter-in-place and stay-at-home orders, quarantines and social distancing guidelines. This may negatively impact the ability of our suppliers to deliver on their commitments to us, our ability to ship our products to our customers and general consumer demand for our products may be negatively impacted by the pandemic and/or government responses thereto.

Many of our products and services are considered to be essential under national and local guidelines. As such, during the COVID-19 pandemic, we generally continued to operate in each of the jurisdictions where we were present. However, certain of our facilities were not able to operate at optimal capacity and any future similarly restrictive measures may have a negative impact on our operations, supply chain and transportation networks, and our products and services may not be considered to be essential in the future. In addition, our customers and suppliers may experience disruptions in their operations and supply chains, which could result in

12

delayed, reduced, or cancelled orders, or collection risks, and which may adversely affect our results of operations and financial condition.

During an epidemic or pandemic, governments may look to re-direct resources and implement austerity measures in the future to balance public finances, which could result in reduced economic activity. Any resulting economic downturn could reduce overall demand for our products, accelerate the erosion of selling prices, lead to reduced revenues and higher inventory levels, any of which could result in a significant deterioration of our results of operations and financial condition.

An epidemic or pandemic may also lead to increased disruption and volatility in capital markets and credit markets. Unanticipated consequences of an epidemic or pandemic and resulting economic uncertainty could adversely affect our liquidity and capital resources in the future.

We may not be able to match our production capacity to demand.

As a result of the cyclicality and volatility of the semiconductor industry, it is difficult to predict future developments in the markets we serve, and, in turn, to estimate requirements for production capacity. If our markets, start-up or ramp-ups in manufacturing operations are not efficiently executed, major customers or certain product designs or technologies do not perform as well as we have anticipated, demand is impacted by factors outside of our or our customers’ control, or if there is otherwise any future excess capacity by us or other semiconductor manufacturers, we risk unused capacity charges, price erosion, write-offs of inventories and losses on products that may adversely impact our operating results, and we could be required to undertake restructuring and transformation measures that may involve significant charges to our earnings. Furthermore, during certain periods, the global supply of semiconductor industry fabrication capacity may not be sufficient to meet the demand for semiconductor products. We may also experience increased demand in certain market segments and product technologies and any future shortage of our capacity and the capacity of our sub-contractors may lead to an increase in the lead times of our delivery to customers, us being required to enter into agreements with our suppliers with onerous terms such as take-or-pay arrangements, or us being unable to service some of our customers, which may result in adverse effects on our customer relationships and in liability claims. Further, as a result of this supply imbalance, the industry in general may experience a high level of profitability and gross margins, which may not be sustainable over the long-term.

Competition in the semiconductor industry is intense, and we may not be able to compete successfully if our product design technologies, process technologies and products do not meet market requirements. Furthermore, the competitive environment of the industry has resulted, and is expected to continue to result, in vertical and horizontal consolidation among our suppliers, competitors and customers, which may lead to erosion of our market share, impact our ability to compete and require us to restructure our operations.

We compete in different product lines to various degrees on certain characteristics, for example, price, technical performance, product features, product design, product availability, process technology, manufacturing capabilities and sales and technical support. Given the intense competition in the semiconductor industry, if our products do not meet market requirements based on any of these characteristics, our business, financial condition and results of operations could be materially adversely affected. Our competitors may have a stronger presence in key markets and geographic regions, greater name recognition, larger customer bases, greater government support and greater financial, research and development, sales and marketing, manufacturing, distribution, technical and other resources than we do. These competitors may be able to adapt more quickly to changes in the business environment, to new or emerging technologies and to changes in customer requirements.

The semiconductor industry is intensely competitive and characterized by the high costs associated with developing marketable products and manufacturing technologies as well as high levels of investment in production capabilities. As a result, the semiconductor industry has experienced, and is expected to continue to experience, significant vertical and horizontal consolidation among our suppliers, competitors and customers. Consolidation in the semiconductor industry could erode our market share, negatively impact our ability to compete and require us to increase our R&D effort, engage in mergers and acquisitions and/or restructure our operations.

Risks Related to Our Operations

13

Our high fixed costs could adversely impact our results.

Our operations are characterized by high fixed or other costs which are difficult to reduce, including costs related to manufacturing, particularly as we operate our own manufacturing facilities, and the employment of our highly skilled workforce. When demand for our products decreases, competition increases or we fail to forecast demand accurately, we may be driven to reduce prices and we may not always be able to decrease our total costs in line with resulting revenue declines. As a result, the costs associated with our operations may not be fully absorbed, leading to unused capacity charges, higher average unit costs and lower gross margins, adversely impacting our results.

Our capital needs are high compared to those competitors who do not manufacture their own products and we may need additional funding in the coming years to finance our investments, to purchase other companies or technologies developed by third parties or to refinance our maturing indebtedness.

As a result of our choice to maintain control of a large portion of our manufacturing technologies and capabilities, we may require significant capital expenditure to maintain or upgrade our facilities if our facilities become inadequate in terms of capacity, flexibility and location. We monitor our capital expenditures taking into consideration factors such as trends in the semiconductor market, customer requirements and capacity utilization. These capital expenditures may increase in the future if we decide to upgrade or expand the capacity of our manufacturing facilities, purchase or build new facilities or increase investments supporting key strategic initiatives. For instance, we may be unable to successfully develop, maintain and operate large infrastructure projects. Such increased capital expenditures associated with large infrastructure projects and strategic initiatives might not achieve profitability or we may be unable to utilize infrastructure projects to full capacity. There can also be no assurance that future market demand and products required by our customers will meet our expectations. We also may need to invest in other companies, in IP and/or in technology developed either by us or by third parties to maintain or improve our position in the market or to reinforce our existing business. Failure to invest appropriately and in a timely manner or to successfully integrate any recent or future business acquisitions may prevent us from achieving the anticipated benefits and could have a material adverse effect on our business and results of operations.

The foregoing may require us to secure additional financing, including through the issuance of debt, equity or both. The timing and the size of any new share or bond offering would depend upon market conditions as well as a variety of other factors. In addition, the capital markets may from time to time offer terms of financing that are particularly favorable. We cannot exclude that we may access the capital markets opportunistically to take advantage of market conditions. Any such transaction or any announcement concerning such a transaction could materially impact the market price of our common shares. If we are unable to access capital on acceptable terms, this may adversely affect our business and results of operations.

Our operating results depend on our ability to obtain quality supplies on commercially reasonable terms. As we depend on a limited number of suppliers for materials, equipment and technology, we may experience supply disruptions if suppliers interrupt supply, increase prices or experience material adverse changes in their financial condition.

Our ability to meet our customers’ demand to manufacture our products depends upon obtaining adequate supplies of quality materials on a timely basis and on commercially reasonable terms. Certain materials are available from a limited number of suppliers or only from a limited number of suppliers in a particular region. We purchase certain materials whose prices on the world markets have fluctuated significantly in the past and may fluctuate significantly in the future. Although supplies for most of the materials we currently use are adequate, shortages could occur in various essential materials due to interruption of supply or increased demand in the industry. For instance, epidemics or pandemics could cause disruptions from the temporary closure of suppliers’ facilities or delays and reduced export or shipment of various materials. Geopolitical conflicts could also disrupt supply chains and cause shortages of certain semiconductor components and corresponding delays in shipments. Any such shortage may impact different geographical markets disproportionately, leading to shortages or unavailability of supplies in specific areas and higher transportation costs. In addition, the costs of certain materials may increase due to recent inflationary rates and market pressures and we may not be able to pass on such cost increases to our customers.

14

We also purchase semiconductor manufacturing equipment and third-party licensed technology from a limited number of suppliers and providers and, because such equipment and technology are complex, it is difficult to replace one supplier or provider with another or to substitute one piece of equipment or type of technology for another. In addition, suppliers and providers may extend lead times, limit our supply, increase prices or change contractual terms related to certain manufacturing equipment and third-party licensed technology, any of which could adversely affect our results. Furthermore, suppliers and technology providers tend to focus their investments on providing the most technologically advanced equipment, materials and technology and may not be able to address our requirements for equipment, materials or technology of older generations. Although we work closely with our suppliers and providers to avoid such shortages, there can be no assurance that we will not encounter these problems in the future.

Consolidation among our suppliers or vertical integration among our competitors may limit our ability to obtain sufficient quantities of materials, equipment and/or technology on commercially reasonable terms and engage in mergers and acquisitions. In certain instances, we may be required to enter into agreements with our suppliers with onerous terms, such as take-or-pay arrangements. If we are unable to obtain supplies of materials, equipment or technology in a timely manner or at all, or if such materials, equipment or technology prove inadequate or too costly, our results of operations could be adversely affected.

Our financial results can be affected by fluctuations in exchange rates, principally in the value of the U.S. dollar.

Currency exchange rate fluctuations affect our results of operations because our reporting currency is the U.S. dollar, in which we receive the major portion of our revenues, while, more importantly, we incur a limited portion of our revenue and a significantly higher portion of our costs in currencies other than the U.S. dollar. A significant variation of the value of the U.S. dollar against the principal currencies that have a material impact on us (primarily the Euro, but also certain other currencies of countries where we have operations, such as the Singapore dollar) could result in a favorable impact, net of hedging, on our net income in the case of an appreciation of the U.S. dollar, or a negative impact, net of hedging, on our net income if the U.S. dollar depreciates relative to these currencies, in particular with respect to the Euro.

In order to reduce the exposure of our financial results to the fluctuations in exchange rates, our principal strategy has been to balance as much as possible the proportion of sales to our customers denominated in U.S. dollars with the amount of purchases from our suppliers denominated in U.S. dollars and to reduce the weight of the other costs, including depreciation, denominated in Euros and in other currencies. In order to further reduce our exposure to U.S. dollar exchange rate fluctuations, we have hedged certain line items on our consolidated statements of income, in particular with respect to a portion of the cost of sales, the majority of the R&D expenses and certain SG&A expenses located in the Euro zone. We also hedge certain manufacturing costs, included within the cost of sales, denominated in Singapore dollars. There can be no assurance that our hedging transactions will prevent us from incurring higher Euro-denominated manufacturing costs and/or operating expenses when translated into our U.S. dollar-based accounts. See “Item 5. Operating and Financial Review and Prospects — Impact of Changes in Exchange Rates” and “Item 11. Quantitative and Qualitative Disclosures About Market Risk”.

Our operating results may vary significantly from quarter to quarter and annually and may also differ significantly from our expectations or guidance.

Our operating results are affected by a wide variety of factors that could materially and adversely affect revenues and profitability or lead to significant variability of our operating results from one period to the next. These factors include changes in demand from our key customers, capital requirements, inventory management, availability of funding, competition, new product developments, start of adoption of our new products by customers, technological changes, manufacturing or supplier issues and effective tax rates. In addition, in periods of industry overcapacity or when our key customers encounter difficulties in their end-markets or product ramps, orders are more exposed to cancellations, reductions, price renegotiation or postponements, which in turn reduce our ability to forecast the next quarter or full year production levels, revenues and margins. As a result, we may not meet our financial targets, which could in turn have an impact on our reputation or brand. For these reasons and others that we may not yet have identified, our revenues and operating results may differ materially from our expectations or guidance as visibility is reduced. See “Item 4. Information on the Company — Backlog”.

15

If our external silicon foundries or back-end subcontractors fail to perform, this could adversely affect our business prospects, financial condition and results of operations.

We currently use external silicon foundries and back-end subcontractors for a portion of our manufacturing activities. Any limitation on the ability of our external silicon foundries and back-end subcontractors to satisfy our demand may cause our results of operations and ability to satisfy the demand of our customers to suffer. Likewise, if we are unable to meet our commitments to silicon foundries and back-end subcontractors, our results of operations could suffer. Prices for these services also vary depending on capacity utilization rates at our external silicon foundries and back-end subcontractors, quantities demanded and product and process technology. Such outsourcing costs can vary materially and, in cases of industry shortages, they can increase significantly, negatively impacting our business prospects, financial condition and results of operations.

Our manufacturing processes are highly complex, costly and potentially vulnerable to impurities, disruptions or inefficient implementation of production changes or interruptions that can significantly increase our costs and delay product shipments to our customers.

Our manufacturing processes are highly complex, require advanced and increasingly costly equipment and are continuously modified or maintained in an effort to improve yields and product performance and lower the cost of production.

Furthermore, impurities or other difficulties in the manufacturing process can lower yields, interrupt production or result in scrap. As system complexity and production changes have increased and sub-micron technology has become more advanced, manufacturing tolerances have been reduced and requirements for precision have become even more demanding. We have from time to time experienced bottlenecks and production difficulties that have caused delivery delays and quality control problems. There can be no assurance that we will not experience bottlenecks or production, transition or other difficulties in the future.

In addition, we are exposed to risks related to interruptions of our manufacturing processes. If any of our property or equipment is damaged or otherwise rendered unusable or inoperable due to accident, cyberattack or otherwise this could result in interruptions which could have a material adverse effect on our business, financial condition and results of operations.

We may experience quality problems from time to time that can result in decreased sales and operating margin and product liability or warranty claims.

We sell complex products that may not in each case comply with specifications or customer requirements, or may contain design or manufacturing defects, that could cause personal injury, property damage or security risks that could be exploited by unauthorized third parties hacking, corrupting or otherwise obtaining access to our products, including the software loaded thereon by us, our suppliers or our customers. Although our general practice is to contractually limit our liability to the repair, replacement or refund of defective products, we occasionally agree to contractual terms with key customers in which we provide extended warranties and accordingly we may face product liability, warranty, delivery failure, and/or other claims relating to our products that could result in significant expenses relating to compensation payments, product recalls or other actions related to such extended warranties and/or to maintain good customer relationships, which could result in decreased sales and operating margin and other material adverse effects on our business. Costs or payments we may make in connection with warranty and other claims or product recalls may adversely affect our results of operations. There can be no assurance that we will be successful in maintaining our relationships with customers with whom we incur quality problems. Furthermore, if litigation occurs we could incur significant costs and liabilities to defend ourselves against such claims. The industry has experienced a rise in premiums and deductibles with regards to insurance policies. These may continue to increase and insurance coverage may also correspondingly decrease. If litigation occurs and damages are awarded against us, there can be no assurance that our insurance policies will be available or adequate to protect us against such claims.

16

Disruptions in our relationships with any one of our key customers or distributors, and/or material changes in their strategy or financial condition or business prospects, could adversely affect our results of operations.

A substantial portion of our sales is derived from a limited number of customers and distributors. There can be no assurance that our customers or distributors will continue to book the same level of sales with us that they have in the past, will continue to succeed in the markets they serve and will not purchase competing products over our products. Many of our key customers and distributors operate in cyclical businesses that are also highly competitive, and their own market positions may vary considerably. In recent years, some of our customers have vertically integrated their businesses. Such vertical integrations may impact our business. Our relationships with the newly formed entities could be either reinforced or jeopardized by the integration. If we are unable to maintain or increase our market share with our key customers or distributors, or if they were to increase product returns or fail to meet payment obligations, our results of operations could be materially adversely affected. Certain of our products are customized to our customers’ specifications. If customers do not purchase products made specifically for them, we may not be able to recover a cancellation fee from our customers or resell such products to other customers. In addition, the occurrence of epidemic or pandemic outbreaks could affect our customers. The geographic spread of epidemics or pandemics may be difficult to predict and adverse public health impacts on our customers could negatively affect our results.

We may experience delays in delivering our product and technology roadmaps as well as transformation initiatives.

Our industry adapts to technological advancements and it is likely that new products, equipment, processes and service methods, including transformation initiatives related to digitalization, are in the process of being implemented. Any failure by us to manage our data governance processes could undermine our initiatives related to digitalization and any failure by us to react to changes or advances in existing technologies and processes as we develop and invest in our product, technology and transformation roadmaps could materially delay the introduction of new solutions. If we are not able to execute on these roadmaps on a timely basis or at an acceptable cost this could result in loss of competitiveness of our solutions, decreased revenue and a loss of market share.

Our computer systems, including hardware, software, information and cloud-based initiatives, are subject to attempted security breaches and other cybersecurity threats, which, if successful, could adversely impact our business.

We have, from time to time, detected and experienced attempts by others to gain unauthorized access to our computer systems and networks. The reliability and security of our information technology infrastructure and software, including our artificial intelligence ("AI")technology, and our ability to expand and continually update technologies, including to transition to cloud-based technologies, in response to our changing needs is critical to our business. In the current environment, there are numerous and evolving risks to cybersecurity, including criminal hackers, state-sponsored intrusions, terrorism, industrial espionage, employee malfeasance, vandalism and human or technological error. Computer hackers and others routinely attempt to breach the security of technology products, services, and systems, and those of our customers, suppliers, partners and providers of third-party licensed technology, and some of those attempts may be successful. Such breaches could result in, for example, unauthorized access to, disclosure, modification, misuse, loss, or destruction of our, our customer, or other third-party data or systems, theft of our trade secrets and other sensitive or confidential data, including personal information and IP, system disruptions, and denial of service.

The attempts to breach our systems, including our cloud-based systems, and to gain unauthorized access to our information technology systems are becoming increasingly more sophisticated. These attempts may include covertly introducing malware into our computers, including those in our manufacturing operations, and impersonating unauthorized users, among others. For instance, employees and former employees, in particular former employees who become employees of our competitors or customers, may misappropriate, use, publish or provide to our competitors or customers our IP and/or proprietary or confidential business information. Also, third parties may attempt to register domain names similar to our brands or website, which could cause confusion and divert online customers away from our products. In the event of such breaches, we, our customers or other third parties could be exposed to potential liability, litigation, and regulatory action, as well as the loss of existing or potential customers, damage to our reputation, and other financial loss and such breaches could also result in losing existing or potential customers in connection with any actual or perceived security

17

vulnerabilities in our systems. In addition, the cost and operational consequences of responding to breaches and implementing remediation measures could be significant. As these threats continue to develop and grow, we have been adapting and strengthening our security measures.

As a result of work-from-home policies that we have undertaken, there has been additional reliance placed on our IT systems and resources. The resulting reliance on these resources, and the added need to communicate by electronic means, could increase our risk of cybersecurity incidents.

Geopolitical instability has been associated with an increase in cybersecurity incidents. This may result in a higher likelihood that we may experience direct or collateral consequences from cybersecurity conflicts between nation-states or other politically motivated actors targeting critical technology infrastructure.

U.S. and foreign regulators have increased their focus on cybersecurity vulnerabilities and risks, and customers and service providers are increasingly demanding more rigorous contractual certification and audit provisions regarding cybersecurity and data governance. This may result in an increase of our overall compliance burden due to increasingly onerous obligations and leading to significant expense. There may also be shorter deadlines in which to notify the authorities of data breaches and ever-increasing fines and penalties for businesses that fail to respond swiftly and appropriately to cyberattacks. Any failure to comply could also result in proceedings against us by regulatory authorities or other third parties.

We continue to increase the resources we allocate to implementing, maintaining and/or updating security systems to protect data and infrastructure and to raising security awareness among those having access to our systems. However, these security measures cannot provide absolute security and there can be no assurance that our employee training, operational, and other technical security measures or other controls will detect, prevent or remediate security or data breaches in a timely manner or otherwise prevent unauthorized access to, damage to, or interruption of our systems and operations.

We regularly evaluate our IT systems and business continuity plan to make enhancements and periodically implement new or upgraded systems, including the transition and migration of our data systems to cloud-based platforms and critical system migration. Any delay in the implementation of, or disruption in the transition to different systems could adversely affect our ability to record and report financial and management information on a timely and accurate basis and could impact our operations and financial position. In addition, a miscalculation of the level of investment needed to ensure our technology solutions are current and up-to-date as technology advances and evolves could result in disruptions in our business should the software, hardware or maintenance of such items become out-of-date or obsolete and the costs of upgrading our cybersecurity systems and remediating damages could be substantial.

We may also be adversely affected by security breaches related to our equipment providers and providers of IT services or third-party licensed technology. As a global enterprise, we could also be impacted by existing and proposed laws and regulations, as well as government policies and practices related to cybersecurity, data privacy and data protection. Additionally, cyberattacks or other catastrophic events resulting in disruptions to or failures in power, information technology, communication systems or other critical infrastructure could result in interruptions or delays to us, our customers, or other third-party operations or services, financial loss, potential liability, damage to our reputation and could also affect our relationships with our customers, suppliers and partners. See “Item 16K. Cybersecurity”.

We may be subject to theft, loss, or misuse of personal data about our employees, customers, or other third parties, which could increase our expenses, damage our reputation, or result in legal or regulatory proceedings.

The theft, loss, or misuse of personal data processed by us could result in significantly increased security costs or costs related to defending legal claims.

Further, with increasing digitalization, data privacy-related legislations are rapidly evolving around the globe which may have a negative impact on our business if interpreted or implemented in a manner that is inconsistent from country to country and inconsistent with the current policies and practices of our customers or business partners. We may also have to change the manner in which we contract with our business partners, store and transfer information and otherwise conduct our business, which could increase our costs and reduce our revenues.

18

Our business is dependent in large part on continued growth in the industries and segments into which our products are sold and on our ability to retain existing customers and attract new ones. A market decline in any of these industries, our inability to retain and attract customers, or customer demand for our products which differs from our projections, could have a material adverse effect on our results of operations.

The demand for our products depends significantly on the demand for our customers’ end products. Growth of demand in the industries and segments into which our products are sold fluctuates significantly and is driven by a variety of factors, including consumer spending, consumer preferences, the development and acceptance of new technologies and prevailing economic conditions. Changes in our customers’ markets and in our customers’ respective shares in such markets could result in slower growth and a decline in demand for our products. In addition, if projected industry growth rates do not materialize as forecasted, our spending on process and product development ahead of market acceptance could have a material adverse effect on our business, financial condition and results of operations.

Our business is dependent upon our ability to retain existing customers. In 2023 our largest customer, Apple, accounted for 12.3% of our total revenues. While we do not believe to be dependent on any one customer or group of customers, the loss of key customers or important sockets at key customers could have an adverse effect on our results of operations and financial condition.

Our existing customers’ product strategy may change from time to time and/or product specifications may change on short-time product life cycles and we have no certainty that our business, financial position and results of operations will not be affected. Our business is also dependent upon our ability to attract new customers. There can be no assurance that we will be successful in attracting and retaining new customers, or in adequately projecting customer demand for our products. Our failure to do so could materially adversely affect our business, financial condition and results of operations.

Market dynamics have driven, and continue to drive us, to a strategic repositioning.

In recent years, we have undertaken several initiatives to reposition our business. Our strategies to improve our results of operations and financial condition have led us, and may in the future lead us, to acquire businesses that we believe to be complementary to our own, to divest ourselves of or wind down activities that we believe do not serve our longer term business plans, or to enter into partnerships or joint ventures to enter into or strengthen our position in certain markets and increase our scale of operations. Our potential acquisition strategies depend in part on our ability to identify suitable acquisition targets, finance their acquisition, obtain approval by our shareholders and obtain required regulatory and other approvals. Our potential divestiture strategies depend in part on our ability to compete and to identify the activities in which we should no longer engage, obtain the relevant approvals pursuant to our governance process and then determine and execute appropriate methods to divest of them. Our actual or potential partnerships and joint venture strategies depend in part on our ability to execute sales and operations plans alongside our partner or joint venture.

We are constantly monitoring our product portfolio and cannot exclude that additional steps in this repositioning process may be required. Furthermore, we cannot assure that any strategic repositioning of our business, including executed and possible future acquisitions, dispositions or partnerships and joint ventures, will be successful and will not result in impairment, restructuring charges and other related closure costs.

Acquisitions, divestitures, partnerships and joint ventures involve a number of risks that could adversely affect our operating results and financial condition, including, in respect of acquisitions and divestitures, the inability for us to successfully integrate businesses or teams that we acquire with our culture and strategies on a timely basis or at all, and the potential requirement for us to record charges related to the goodwill or other long-term assets associated with the acquired businesses. There can be no assurance that we will be able to achieve the full scope of the benefits we expect from a particular acquisition, divestiture, partnership, joint venture or investment. Our business, financial condition and results of operations may suffer if we fail to coordinate our resources effectively to manage both our existing businesses and any acquired businesses. In addition, the financing of future acquisitions, divestitures, partnerships or joint ventures may negatively impact our financial position, including our ability to pay a dividend and/or repurchase our shares, and our credit rating and we could be required to raise additional funding.

Other risks associated with acquisitions include the assumption of potential liabilities, disclosed or undisclosed, associated with the business acquired, which liabilities may exceed the amount of indemnification

19

available from the seller, potential inaccuracies in the financials of the business acquired, and our ability to retain customers of an acquired entity, its business or industrialize an acquired process or technology. Identified risks associated with divestitures include loss of activities and technologies that may have complemented our remaining businesses or operations and loss of important services provided by key employees that are assigned to divested activities.

We depend on collaboration with other semiconductor industry companies, research organizations, universities, customers and suppliers to further our R&D efforts, and our business and prospects could be materially adversely affected by the failure or termination of such alliances.

Our success depends on our ability to introduce innovative new products and technologies to the marketplace on a timely basis. In light of the high levels of investment required for R&D activities, we depend in certain instances on collaborations with other semiconductor industry companies, research organizations, universities, customers and suppliers to develop or access new technologies.

Such collaboration provides us with a number of important benefits, including the sharing of costs, reductions in our own capital requirements, acquisitions of technical know-how and access to additional production capacities. However, there can be no assurance that our collaboration efforts will be successful and allow us to develop and access new technologies in due time, in a cost-effective manner and/or to meet customer demands. If a particular collaboration terminates before our intended goals are accomplished we may incur additional unforeseen costs, and our business and prospects could be adversely affected. Furthermore, if we are unable to develop or otherwise access new technologies, whether independently or in collaboration with another industry participant, we may fail to keep pace with the rapid technology advances in the semiconductor industry, our participation in the overall semiconductor industry may decrease and we may also lose market share.

We depend on patents to protect our rights to our technology and may face claims of infringing the IP rights of others.

We depend on patents and other IP rights to protect our products and our manufacturing processes against misappropriation by others. The process of seeking patent protection can be long and expensive, and there can be no assurance that that we will receive patents from currently pending or future applications. Even if patents are issued, they may not be of sufficient scope or strength to provide meaningful protection or any commercial advantage. In addition, effective IP protection may be unavailable or limited in some countries. Our ability to enforce one or more of our patents could be adversely affected by changes in patent laws, laws in certain foreign jurisdictions that may not effectively protect our IP rights or by ineffective enforcement of laws in such jurisdictions. Competitors may also develop technologies that are protected by patents and other IP and therefore either be unavailable to us or be made available to us subject to adverse terms and conditions. We have in the past used our patent portfolio to negotiate broad patent cross-licenses with many of our competitors enabling us to design, manufacture and sell semiconductor products, without concern of infringing patents held by such competitors. We may not in the future be able to obtain such licenses or other rights to protect necessary IP on favorable terms for the conduct of our business, and such failure may adversely impact our results of operations. Such cross-license agreements expire from time to time and there is no assurance that we can or we will extend them.

We have from time to time received, and may in the future receive, communications alleging possible infringement of third-party patents and other IP rights. Some of those claims are made by so-called non-practicing entities against which we are unable to assert our own patent portfolio to lever licensing terms and conditions. Competitors with whom we do not have patent cross-license agreements may also develop technologies that are protected by patents and other IP rights and which may be unavailable to us or only made available on unfavorable terms and conditions. We may therefore become involved in costly litigation brought against us regarding patents and other IP rights. See Note 25 to our Consolidated Financial Statements. IP litigation may also involve our customers who in turn may seek indemnification from us should we not prevail and/or who may decide to curtail their orders for those of our products over which claims have been asserted. Such lawsuits may therefore have a material adverse effect on our business. We may be forced to stop producing substantially all or some of our products or to license the underlying technology upon economically unfavorable terms and conditions or we may be required to pay damages for the prior use of third-party IP and/or face an injunction.

20

The outcome of IP litigation is inherently uncertain and may divert the efforts and attention of our management and other specialized technical personnel. Such litigation can result in significant costs and, if not resolved in our favor, could materially and adversely affect our business, financial condition and results of operations.

We operate in many jurisdictions with highly complex and varied tax regimes. Changes in tax rules, new or revised legislation or the outcome of tax assessments and audits could cause a material adverse effect on our results.

We operate in many jurisdictions with highly complex and varied tax regimes. Changes in tax rules, new or revised legislation or the outcome of tax assessments and audits could have a material adverse effect on our results.

In 2021, the Organization for Economic Cooperation and Development (OECD) and the G20 Inclusive Framework on base erosion and profit shifting (BEPS) agreed to a two-pillar solution to address the tax challenges arising from the digitalization of the economy. Pillar I is a set of proposals to revisit tax allocation rules in a changed economy. The intention is that a portion of a multinationals' residual profit is taxed in the jurisdiction where revenue is sourced.

Pillar II enforces a global minimum corporate income tax at an effective rate of 15% for large multinationals. On December 20, 2021 the OECD published the Global Anti-Base Erosion Model Rules ("GloBe Rules") for Pillar II. On December 22, 2021, the European Commission published a legislative proposal for Pillar II (the "EU Pillar II Directive").

On December 15, 2022, the Council of the European Union formally adopted the EU Pillar II Directive. The EU Pillar II Directive aims at consistently implementing among all 27 member states the GloBe Rules. EU Member States will have to transpose the EU Pillar II Directive into their national laws and will have to apply the Pillar II measures in respect of the fiscal years beginning on or after December 31, 2023. The Netherlands have transposed the EU Pillar II Directive into its national legislation with effect from December 31, 2023 pursuant to the Dutch Minimum Tax Act 2024 (Wet minimumbelasting 2024).

The tax impact of the Pillar I and Pillar II rules is monitored to determine the potential effect on our results and to ensure compliance when the legislation is effective. The impact on the Company's tax position will depend on the changes in the level of tax results within various local jurisdiction and the potential adoption of the legislation in the jurisdiction where the Company operates in 2024. Therefore no quantitative tax impact on the Company's tax position is provided as per December 31, 2023.

Our tax rate is variable and depends on changes in the level of operating results within various local jurisdictions and on changes in the applicable taxation rates of these jurisdictions, as well as changes in estimated tax provisions due to new events. We currently receive certain tax benefits or benefit from net operating losses cumulated in prior years in some countries, and these benefits may not be available in the future due to changes in the local jurisdictions or credits on net operating losses being no longer available due to either full utilization or expiration of the statute of limitations in such jurisdictions. As a result, our effective tax rate could increase and/or our benefits from carrying forward net operating losses could affect our deferred tax assets in certain countries in the coming years. In addition, the acquisition or divestiture of businesses in certain jurisdictions could materially affect our effective tax rate.

We evaluate our deferred tax asset position and the need for a valuation allowance on a regular basis. The ultimate realization of deferred tax assets is dependent upon, among other things, our ability to generate future taxable income that is sufficient to utilize in certain jurisdictions loss carry-forwards or tax credits before their expiration or our ability to implement prudent and feasible tax optimization strategies. The recorded amount of total deferred tax assets could be reduced, which could have a material adverse effect on our results of operations and financial position, if our estimates of projected future taxable income and benefits from available tax strategies are reduced as a result of a change in business condition or in management’s plans or due to other factors, such as changes in tax laws and regulations.

We are subject to the possibility of loss contingencies arising out of tax claims, assessment of uncertain tax positions and provisions for specifically identified income tax exposures. We are also subject to tax audits in certain jurisdictions. There can be no assurance that we will be successful in resolving potential tax claims that

21

result from these audits, which could result in material adjustments in our tax positions. We record provisions on the basis of the best current understanding; however, we could be required to record additional provisions in future periods for amounts that cannot currently be assessed. Our failure to do so and/or the need to increase our provisions for such claims could have a material adverse effect on our results of operations and our financial position.

Our operating results can vary significantly due to impairment of goodwill, other intangible assets and equity investments booked pursuant to acquisitions and the timeframe required to foster and realize synergies thereof, joint venture agreements and the purchase of technologies and licenses from third parties, as well as to impairment of tangible assets due to changes in the business environment. Because the market for our products is characterized by rapidly changing technologies, significant changes in the semiconductor industry, and the potential failure of our business initiatives, our future cash flows may not support the value of goodwill, tangible assets and other intangibles registered in our consolidated balance sheets. See “Item 5. Operating and Financial Review and Prospects— Critical Accounting Policies Using Significant Estimates — Impairment of goodwill”, “— Intangible assets subject to amortization” and “Item 4. Information on the Company — Property, Plants and Equipment”.

We receive public funding, and a reduction in the amount available to us or demands for repayment could increase our costs and impact our results of operations.

We have in the past obtained public funding, primarily to support our proprietary R&D for technology investments and investments in cooperative R&D ventures, and expect to obtain public funding in the future, mainly from EU member states (including France, Italy and Malta). The public funding we receive is subject to periodic review by the relevant authorities and there can be no assurance that we will continue to benefit from such programs at current levels or that sufficient alternative funding will be available if we lose such support. If any of the public funding programs we participate in are curtailed or discontinued and we do not reduce the relevant R&D or other costs, this could have a material adverse effect on our business. Furthermore, to receive public funding, we enter into agreements which require compliance with extensive regulatory requirements and set forth certain conditions relating to the funded programs. If we fail to meet the regulatory requirements or applicable conditions, we may, under certain circumstances, be required to refund previously received amounts, which could have a material adverse effect on our results of operations. If there are changes in the public funding we receive this could increase the net costs for us to, amongst others, continue investing in R&D at current levels and could result in a material adverse effect on our results of operations.

A change in the landscape in public funding may also affect our business. For example, the European Chips Act which entered into force on September 21, 2023 and is designed to bolster Europe’s competitiveness and resilience in semiconductor technologies and applications and any similar proposals in other regions, may provide public funding towards manufacturing activities of semiconductors. It is yet to be seen whether this would impact the amount of public funding currently available to us for our R&D or other investments and ventures, but any reduction in said funding will result in a material adverse effect on our results of operations. Further, this may result in new or existing competitors benefiting from such funding and could also have an impact on the competitive landscape in our industry. See “Item 4. Information on the Company — Public Funding”.

Some of our production processes and materials are environmentally sensitive, which could expose us to liability and increase our costs due to environmental, health and safety laws and regulations or because of damage to the environment.

We are subject to various laws and regulations, as well as increasing focus from our stakeholders regarding environmental, health and safety matters, including the use, storage, discharge and disposal of chemicals, gases and other hazardous substances used in our operations. Addressing such focus from stakeholders, as well as compliance with such laws and regulations could adversely affect our manufacturing costs or product sales by requiring us to acquire costly equipment, materials or greenhouse gas allowances, or to incur other significant expenses in adapting our manufacturing processes or waste and emission disposal processes. Furthermore, environmental claims or our failure to comply with present or future regulations could result in the assessment of damages or imposition of fines against us, suspension of production or a cessation of operations. Failure by us to control the use of, or adequately restrict the discharge of, chemicals or hazardous substances could subject us to future liabilities.

22

Climate change and related sustainability regulations and initiatives, including our commitment to become carbon neutral by 2027 on scope 1 and 2 and partially scope 3, could place additional burden on us and our operations.

As climate change issues become more pronounced, we may correspondingly face increased regulation and also expectations from our stakeholders to take actions beyond existing regulatory requirements to minimize our impact on the environment and mitigate climate change related effects. The semiconductor manufacturing process has historically contributed to direct greenhouse gas emissions by utilizing perfluorocarbons, which may lead to new or increased regulation of such compounds. In order to address such regulation, we may be required to adapt our production processes or purchase additional equipment or carbon offsets, leading to increased costs. As of the end of 2023, we are on track towards our goal to become carbon neutral by 2027 on scope 1 and 2 and partially scope 3, which includes two specific targets: compliance with the 1.5°C scenario defined at the Paris COP21 by 2025, implying a 50% reduction of direct and indirect greenhouse gas emissions compared to 2018, and the sourcing of 100% renewable energy by 2027 (as further explained below in “Item 4. – Environmental, Health and Safety Matters”).

To meet these additional requirements, we will need to continue to deploy additional equipment, introduce process changes, utilize alternative suppliers and materials, and take other similar actions, some or all of which may require us to incur additional costs which could result in a material adverse effect on our results of operations and our financial condition. In addition, if we fail to meet these expectations, or foster additional sustainability initiatives, we may experience reputational risk which could impact our ability to attract and retain customers, employees, and investors.

Further, our sites, as well as those of our partners along the supply chain, may be exposed to changing and/or increasing physical risks resulting from climate change that are either chronic (induced by longer-term shifts in climate patterns, such as sea level rise or constraints in the availability of water, changing temperature, wind or precipitation patterns) or acute (event-driven such as cyclones, hurricanes or heat waves). In the context of the transition to a lower-carbon economy, we will likely be exposed to further policy, legal, technology, and market transition risks. We have already seen further policy developments in this area in the form of Regulation (EU) 2020/852 of the European Parliament and of the Council of June 18, 2020 on the establishment of a framework to facilitate sustainable investment and amending Regulation (EU) 2019/2088 (the “EU Taxonomy Regulation”), which entered into force on July 12, 2020. As a result of the EU Taxonomy Regulation, we must disclose information on how and to what extent our activities are associated with economic activities that qualify as environmentally sustainable. See “Item 4. Information on the Company – Environmental, Health and Safety Matters”.

Directive (EU) 2022/2464 of the European Parliament and of the Council of December 14, 2022 amending Regulation (EU) No 537/2014, Directive 2004/109/EC, Directive 2006/43/EC and Directive 2013/34/EU, as regards corporate sustainability reporting (the “CSRD”), which entered into force on January 5, 2023 and which will apply to our reporting as of financial year 2024, strengthens the rules regarding social and environmental information that is required to be reported. The CSRD seeks to provide investors and other stakeholders with access to the information they need to assess investment risks arising from climate change and other sustainability topics. The CSRD further makes it mandatory for us to have an audit of the sustainability information that we report on. If our disclosure metrics relating to climate change and other sustainability topics are lower than those of our peers in the industry, this may lead to reputational risk which may lead to onward financial repercussions such as a decrease in share price or difficulty in raising capital.

Loss of key employees and the inability to continuously recruit and retain qualified employees could hurt our competitive position.

Our success depends to a significant extent upon our key executives and R&D, engineering, marketing, sales, manufacturing, support and other personnel. Our success also depends upon our ability to continue to identify, attract, retain and motivate highly trained and skilled engineering, technical and professional personnel in a competitive recruitment environment, as well our ability to ensure the smooth succession and continuity of business with newly hired and promoted personnel. For instance, in highly specialized areas, it may become more difficult to retain employees.

23

Our employee hiring and retention also depend on our ability to build and maintain a diverse and inclusive workplace culture and be viewed as an employer of choice. We intend to continue to devote significant resources to recruit, train and retain qualified employees, however, we may not be able to attract, obtain and retain these employees, which may affect our growth in future years and the loss of the services of any of these key personnel without adequate replacement or the inability to attract new qualified personnel could have a material adverse effect on us.

The interests of our controlling shareholder, which is in turn indirectly controlled by the French and Italian governments, may conflict with other investors’ interests. In addition, our controlling shareholder may sell our existing common shares or issue financial instruments exchangeable into our common shares at any time.

We understand that as of December 31, 2023, STMicroelectronics Holding N.V. (“ST Holding”), owned 250,704,754 shares, or approximately 27.5%, of our issued common shares. ST Holding may therefore be in a position to effectively control the outcome of decisions submitted to the vote at our shareholders’ meetings, including but not limited to the appointment of the members of our Managing and Supervisory Boards.

We have been informed that ST Holding’s shareholders, each of which is ultimately controlled by the French or Italian government, are party to a shareholders agreement (the “STH Shareholders Agreement”), which governs relations between them. We are not a party to the STH Shareholders Agreement. See “Item 7. Major Shareholders and Related Party Transactions — Major Shareholders”. The STH Shareholders Agreement includes provisions requiring the unanimous approval by the shareholders of ST Holding before ST Holding can vote its shares in our share capital, which may give rise to a conflict of interest between our interests and investors’ interests, on the one hand, and the (political) interests of ST Holding’s shareholders, on the other hand. Our ability to issue new shares or other securities giving access to our shares may be limited by ST Holding’s desire to maintain its shareholding at a certain level and our ability to buy back shares may be limited by ST Holding due to a Dutch law requiring one or more shareholders acquiring 30% or more of our voting rights to launch a tender offer for our outstanding shares.

The STH Shareholders Agreement also permits our respective French and Italian indirect shareholders to direct ST Holding to dispose of its stake in us at any time, thereby reducing the current level of their respective indirect interests in our common shares. Sales of our common shares or the issuance of financial instruments exchangeable into our common shares or any announcements concerning a potential sale by ST Holding could materially impact the market price of our common shares depending on the timing and size of such sale, market conditions as well as a variety of other factors.

Our shareholder structure and our preference shares may deter a change of control.

We have an option agreement in place with an independent foundation, whereby the foundation can acquire preference shares in the event of actions which the board of the independent foundation determines would be contrary to our interests, our shareholders and our other stakeholders and which in the event of a creeping acquisition or offer for our common shares are not supported by our Managing Board and Supervisory Board. In addition, our shareholders have authorized us to issue additional capital within the limits of the authorization by our Annual General Meeting of Shareholders (“AGM”), subject to the requirements of our Articles of Association, without the need to seek a specific shareholder resolution for each capital increase. Accordingly, an issue of preference shares or new shares may make it more difficult for a shareholder to obtain control over our general meeting of shareholders. These anti-takeover provisions could substantially impede the ability of our shareholders to benefit from a change in control and, as a result, may materially adversely affect the market price of our ordinary shares and our investors’ ability to realize any potential change of control premium. See “Item 7. Major Shareholders and Related Party Transactions — Major Shareholders — Preference Shares”.

Any decision to reduce or discontinue paying cash dividends to our shareholders could adversely impact the market price of our common shares.

On an annual basis, our Supervisory Board, upon the proposal of the Managing Board, may propose the distribution of a cash dividend to the general meeting of shareholders. See “Item 8. Dividend Policy”. Any

24

reduction or discontinuance by us of the payment of cash dividends at historical levels could cause the market price of our common shares to decline.

We are required to prepare financial statements under IFRS and we also prepare Consolidated Financial Statements under U.S. GAAP, and such dual reporting may impair the clarity of our financial reporting.

We use U.S. GAAP as our primary set of reporting standards. Applying U.S. GAAP in our financial reporting is designed to ensure the comparability of our results to those of our competitors, as well as the continuity of our reporting, thereby providing our stakeholders and potential investors with a clear understanding of our financial performance. As we are incorporated in The Netherlands and our shares are listed in Europe on Euronext Paris and on the Borsa Italiana, we are subject to EU regulations requiring us to also report our results of operations and financial statements using IFRS.

As a result of the obligation to report our financial statements under IFRS, we prepare our results of operations using both U.S. GAAP and IFRS, which are currently not consistent. Such dual reporting can materially increase the complexity of our financial communications. Our financial position and results of operations reported in accordance with IFRS will differ from our financial position and results of operations reported in accordance with U.S. GAAP, which could give rise to confusion in the marketplace.

There are inherent limitations on the effectiveness of our controls.

There can be no assurance that a system of internal control over financial reporting, including one determined to be effective, will prevent or detect all misstatements. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance regarding financial statement preparation and presentation. Projections of the results of any evaluation of the effectiveness of internal control over financial reporting into future periods are subject to inherent risk. The relevant controls may become inadequate due to changes in circumstances or the degree of compliance with the underlying policies or procedures may deteriorate.

Because we are subject to the corporate law of The Netherlands, U.S. investors might have more difficulty protecting their interests in a court of law or otherwise than if we were a U.S. company.

Our corporate affairs are governed by our Articles of Association and by the laws governing corporations incorporated in The Netherlands. The rights of our investors and the responsibilities of members of our Managing and Supervisory Boards under Dutch law are not as clearly established as under the rules of some U.S. jurisdictions. Therefore, U.S. investors may have more difficulty in protecting their interests in the face of actions by our management, members of our Managing and Supervisory Boards or our controlling shareholders than U.S. investors would have if we were incorporated in the United States.

Our executive offices and a substantial portion of our assets are located outside the United States. In addition, ST Holding and most members of our Managing and Supervisory Boards are residents of jurisdictions other than the United States. As a result, it may be difficult or impossible for shareholders to effect service within the United States upon us, ST Holding, or members of our Managing or Supervisory Boards. It may also be difficult or impossible for shareholders to enforce outside the United States judgments obtained against such persons in U.S. courts, or to enforce in U.S. courts judgments obtained against such persons in courts in jurisdictions outside the United States. This could be true in any legal action, including actions predicated upon the civil liability provisions of U.S. securities laws. In addition, it may be difficult or impossible for shareholders to enforce, in original actions brought in courts in jurisdictions located outside the United States, rights predicated upon U.S. securities laws.

We have been advised by Dutch counsel that the United States and The Netherlands do not currently have a treaty providing for reciprocal recognition and enforcement of judgments (other than arbitration awards) in civil and commercial matters. With respect to choice of court agreements in civil or commercial matters, it is noted that the Hague Convention on Choice of Court Agreements entered into force in The Netherlands, but has not entered into force in the United States. As a consequence, a final judgment for the payment of money rendered by any federal or state court in the United States based on civil liability, whether or not predicated solely upon the federal securities laws of the United States, will not be enforceable in The Netherlands.

25

However, if the party in whose favor such final judgment is rendered brings a new suit in a competent court in The Netherlands, such party may submit to The Netherlands court the final judgment that has been rendered in the United States. If The Netherlands court finds that the jurisdiction of the federal or state court in the United States has been based on grounds that are internationally acceptable and that proper legal procedures that are in accordance with the Dutch standards of proper administration of justice including sufficient safeguards (behoorlijke rechtspleging) have been observed, the court in The Netherlands would, under current practice, in principle give binding effect to the final judgment that has been rendered in the United States unless such judgment contradicts The Netherlands’ public policy and provided that the judgment by the foreign court is not incompatible with a decision rendered between the same parties by a Dutch court, or with a previous decision rendered between the same parties by a foreign court in a dispute that concerns the same subject and is based on the same cause, provided that the previous decision qualifies for acknowledgment in The Netherlands. Even if such a foreign judgment is given binding effect, a claim based thereon may, however, still be rejected if the foreign judgment is not or no longer formally enforceable.

Item 4.    Information on the Company

Business Overview

We are a global semiconductor company that designs, develops, manufactures and markets a broad range of products used in a wide variety of applications for the four end-markets we address: automotive, industrial, personal electronics and communications equipment, computers and peripherals. For the automotive and industrial markets we address a wide customer base, particularly in industrial, with a broad and deep product portfolio. In personal electronics and communications equipment, computers and peripherals we have a selective approach both in terms of the customers we serve, as well as in the technologies and products we offer, while leveraging our broad portfolio to address high-volume applications.

Our diverse product portfolio includes discrete and general purpose components, application-specific integrated circuits (“ASICs”), full-custom devices and semi-custom devices and application-specific standard products (“ASSPs”) for analog, digital and mixed-signal applications. It benefits from a unique, strong foundation of proprietary and differentiated leading-edge technologies. We use all of the prevalent function-oriented process technologies, including complementary metal-on silicon oxide semiconductors (“CMOS”), bipolar and non-volatile memory technologies. In addition, by combining basic processes, we have developed advanced systems-oriented technologies that enable us to produce differentiated and application-specific products, including fully depleted silicon-on-insulator (“FD-SOI”) technology offering superior performance and power efficiency compared to bulk CMOS, bipolar CMOS (“Bi-CMOS”) and radio frequency silicon-on-insulator (“RF-SOI”) for mixed-signal and high-frequency applications, as well as a combination of Bipolar, CMOS and DMOS (“BCD”), vertically integrated power (“VIPower”), and intelligent integrated gallium-nitride (STI2GaN) technologies for smart power applications, Power MOSFET, silicon carbide (“SiC”) and gallium-

26

nitride (“GaN”) for high-efficiency systems, Micro-Electro-Mechanical Systems (“MEMS”) technologies for sensors and actuators, embedded memory technologies for our microcontrollers and differentiated optical sensing technologies for our optical sensing solutions. For our 2023 Results of Operations, see “Item 5. Operating and Financial Review and Prospects — Results of Operations — Segment Information”.

Strategy

We have over 50,000 creators and makers of semiconductor technologies mastering the semiconductor supply chain with state-of-the-art manufacturing facilities. As an integrated device manufacturer, we work with more than 200,000 customers and thousands of partners to design and build products, solutions, and ecosystems that address their challenges and opportunities, and the need to support a more sustainable world. Our technologies enable smarter mobility, more efficient power and energy management, and the wide-scale deployment of cloud-connected autonomous things. We are committed to achieving our goal to become carbon neutral on scope 1 and scope 2 and partially on scope 3 by 2027.

Our strategy focuses on long-term value creation for the Company and its affiliated enterprises and takes into account the short-, medium- and longer-term evolution of the markets we serve and the environment and opportunities we see. It stems from key long-term enablers: Smart Mobility, where we provide innovative solutions to help car manufacturers make driving safer, greener and more connected; Power & Energy: our technology and solutions enable industries to increase energy efficiency and support the use of renewable energy and cloud-connected autonomous things; which transform our lives and the objects we use with smart, connected devices for personal, business and industrial applications.

We are focused on application areas which are expected to experience solid growth rates driven by broad, long-term trends in electronic systems. These trends require enablers such as autonomous systems, robotics, securely connected machines and personal devices, digitalization and electrification of automobiles and infrastructure, advanced communications equipment and networks and more power efficient systems. These enablers drive in turn the demand for the electronic components we develop and manufacture.

Product Information

Alliances with Customers and Industry Partnerships

We believe that customer alliances and industry partnerships are critical to our success in the semiconductor market. Customer alliances provide us with valuable systems and application know-how and access to markets for key products, while enabling our customers to gain access to our technologies and manufacturing infrastructure. We are actively working to expand the number of our customer alliances, targeting key global OEMs as well as emerging, innovative customers and partners around the globe.

From time to time we collaborate with other semiconductor industry companies, research organizations, universities, customers, experts and suppliers to further our R&D efforts. Such collaboration provides us with a number of important benefits, including acquisition of technical know-how, access to additional production capacities, sharing of costs and reductions in our own capital requirements.

Customers and Applications

We design, develop, manufacture and market thousands of products which we sell to over 200,000 customers. We emphasize a broad and balanced product portfolio, in the applications and regional markets we serve, which helps foster closer, strategic relationships with customers. Our major customers include Apple, Bosch, Continental, HP, Huawei, Hyundai Motor, Mobileye, Samsung, SpaceX and Tesla. This broad product breadth provides opportunities to enable application solutions and to supply such customers’ requirements for all their product and technology needs. We also sell our products through our distribution channel.

In Automotive, we have identified a significant evolution of the relationship with customers. Historically, semiconductor companies addressed the needs of carmakers mostly through tier-1 and/or tier-2 automotive industry suppliers with whom we work closely. In recent years there has been an accelerated transformation of the automotive industry driven by the electrification and the digitalization of vehicles, significantly increasing the amount and complexity of semiconductor products in vehicles. As a result, and following further from the supply chain challenges which arose during and after the COVID-19 pandemic, carmakers are taking a more direct role in the decision making and control of both the semiconductor strategy and supply for their vehicles. Carmakers now have a more direct relationship with companies such as ours, notably playing a more active role in defining the specific solutions they require, as well as in certain instances engaging in direct co-operation agreements, including multi-year agreements to secure capacity corridors. We are committed to playing a major role in these new business models and we see multiple opportunities for co-operation with carmakers in this area, while also continuing to build on our co-operation with tier-1 and tier-2 automotive industry suppliers.

Sales, Marketing and Distribution

Our sales and marketing is organized by a combination of regional and key account coverage with the primary objective of accelerating sales growth and gaining market share. Emphasis is placed on strengthening the development of our global and major local accounts; boosting demand creation through an enhanced focus on geographical and key account coverage with strong technical and application expertise, supported in the mass market by our distribution channel and local initiatives; and establishing regional sales and marketing teams that are fully aligned with our strategic end-markets: automotive, industrial, personal electronics and communications equipment, computers and peripherals.

We have four regional sales organizations reporting to a global head of Sales & Marketing: Americas, APeC (Asia Pacific excluding China), China and EMEA (Europe, Middle-East and Africa). Our regional sales organizations have a similar structure to enhance global coordination and go-to-market activities. The sales and marketing teams are strongly focused on profitable revenue growth and business performance as well as on fostering demand creation, expanding the customer base, maximizing market share, developing new product-

32

roadmaps and providing the best technical and application support in the field for our customers. The sales and marketing activities are supported by sales engineers, system marketing, product marketing, application labs, competence centers, field application engineers and quality engineers.

In the first quarter of 2024, we announced that we will complement the existing Sales & Marketing organization by implementing a new application-specific marketing organization by segment, offering customers end-to-end system solutions based on our product and technology portfolio, covering the following four end markets:

•Automotive;

•Industrial Power and Energy;

•Industrial Automation, IoT and AI; and

•Personal Electronics, Communication Equipment and Computer Peripherals.

The current regional Sales & Marketing organization will remain unchanged.

We engage distributors and sales representatives to distribute and promote our products around the world. Typically, distributors handle a wide variety of products, including those that compete with ours. Our distributors have a dual role, in that they assist in fulfilling the demand of our customers by servicing their orders, while also supporting the creation of product demand and business development. Most of our sales to distributors are made under specific agreements allowing for price protection and stock rotation for unsold merchandise. Sales representatives, on the other hand, generally do not offer products that compete directly with our products, but may carry complementary items manufactured by others.

At the request of certain customers, we also sell and deliver our products to electronics manufacturing services (“EMS”) companies, which, on a contractual basis with our customers, incorporate our products into the application specific products they manufacture for our customers. We also sell products to original design manufacturers (“ODM”). ODMs manufacture products for our customers much like EMS companies do, but they also design applications for our customers, and in doing so themselves select the products and suppliers that they wish to purchase from. In furtherance of our strong commitment to quality, our sales organizations include personnel dedicated to close monitoring and resolution of quality-related issues. For a breakdown of net revenues by segment and geographic region for the last three fiscal years, see “Item 5. Operating and Financial Review and Prospects”.

Research and Development

We believe that market driven R&D based on leading-edge products and technologies is critical to our success. We devote significant effort to R&D because we believe such investment can be leveraged into competitive advantages: about 18% of our employees work in R&D on product design/development and technology and, in 2023, we spent approximately 12.2% of our net revenues on R&D.

New developments in semiconductor technology can make end products significantly cheaper, smaller, faster, more reliable and embedded than their predecessors, with differentiated functionalities. They can enable significant value creation opportunities with their timely appearance on the market. Our innovations in semiconductor technology as well as in hardware and software contribute to the creation of successful products that generate value for us and our customers. Our complete design platforms, including a large selection of IP and silicon-proven models and design rules, enable the fast development of products designed to meet customer expectations in terms of reliability, quality, competitiveness in price and time-to-market. Through our R&D efforts, we contribute to making our customers’ products more efficient, more appealing, more reliable and safer.

Our technology R&D strategy is based on the development of differentiated technologies, allowing for a unique offer in terms of new products and enabling new applications opportunities. We draw on a rich pool of chip fabrication technologies, including advanced CMOS, FD-SOI, RF-SOI, optical sensing, embedded non-volatile memories, mixed-signal, analog, MEMS, smart power, SiC and GaN processes. This is well embedded in our strong packaging technologies portfolio such as high pin count BGA, wafer level packaging, highly integrated sensor packages and leadframe package power products. We combine both front-end and back-end manufacturing and technology R&D under the same organization to ensure a smooth flow of information

33

between our R&D and manufacturing organizations. We leverage significant synergies and shared activities between our product groups to cross-fertilize them. We also use silicon foundries, especially for advanced CMOS beyond the 18 nm node that we do not plan to manufacture nor develop internally.

We have advanced R&D and innovation centers which offer us a significant advantage in quickly and cost effectively introducing products. Furthermore, we have established a strong culture of partnerships and through the years have created a network of strategic collaborations with key customers, suppliers, competitors, and leading universities and research institutes around the world. See “Item 4. Information on the Company — Alliances with Customers and Industry Partnerships”. We also play leadership roles in numerous projects running under the European Union’s IST (Information Society Technologies) programs. We also participate in certain R&D programs established by the EU, individual countries and local authorities in Europe (primarily in France and Italy). See “Item 4. Information on the Company — Public Funding”.

The total amount of our R&D expenses in the past three fiscal years was $2,100 million, $1,901 million and $1,723 million in 2023, 2022 and 2021, respectively. For more information on our R&D expenses, see “Item 5. Operating and Financial Review and Prospects — Results of Operations — Research and Development Expenses”.

_______________

(1)    This table does not include the new 200mm silicon carbide device manufacturing joint venture with Sanan Optoelectronics in Chongqing, China, which we are currently building as we announced on June 7 2023. See “Item 5. Operating and Financial Review and Prospects - Financial outlook: Capital Investment” and Notes 7, 10 and 12 of the Consolidated Financial Statements.

(2)     Fab 3 is currently shared between the Company and Tower Semiconductor.

(3)     We are currently building a new integrated Silicon Carbide (SiC) substrate manufacturing facility for the production in volume of 200mm SiC epitaxial substrates, to support the increasing demand from our customers for SiC devices across automotive and industrial applications. Certain operations have also started in December 2023. The investment of €730 million over five years will benefit from a financial support of up to €292.5 million through the Italian Recovery and Resilience Plan.

(4)    We are in the process of building a new, jointly-operated 300mm semiconductor manufacturing facility with GlobalFoundries Inc, following the approval received from the European Commission. This project represents an overall projected cost of €7.5 billion of capital expenditure, maintenance and ancillary costs and will benefit from significant financial support of up to roughly €2.9 billion from the State of France in line with the objectives set out in the European Chips Act.

36

(5)    Jointly owned with SHIC, a subsidiary of Shenzhen Electronics Group.

At December 31, 2023, our front-end facilities had a total maximum capacity of approximately 140,000 wafer starts per week (200mm equivalent). The number of wafer starts per week varies from facility to facility and from period to period as a result of changes in product mix.

We own all of our manufacturing facilities, but certain facilities (Muar, Malaysia; Shenzhen, China; Kirkop, Malta; and Toa Payoh and Ang Mo Kio, Singapore) are built on land subject to long-term leases.

We have historically subcontracted a portion of total manufacturing volumes to external suppliers. In 2023, we subcontracted approximately 20% of the value of our total silicon production to external foundries. Our plan is to continue sourcing silicon from external foundries to give us flexibility in supporting our growth.

At December 31, 2023, we had approximately $1,899 million in outstanding orders for purchases of equipment (certain of which are subject to cancellation or amendment in accordance with their terms) and other assets for delivery in 2024. In 2023, our capital expenditure payments, net of proceeds from sales, capital grants and other contributions, was $4,111 million compared to $3,524 million in 2022. In the 2021-2023 period the ratio of capital expenditure payments, net of proceeds from sales, capital grants and other contributions to net revenues was about 20%. For more information, see “Item 5. Operating and Financial Review and Prospects — Financial Outlook: Capital Investment”.

Intellectual Property (IP)

Our success depends in part on our ability to obtain patents, licenses and other IP rights to protect our proprietary technologies and processes. IP rights that apply to our various products include patents, copyrights, trade secrets, trademarks and mask work rights. We currently own approximately 20,000 patents and pending patent applications.

We believe that our IP represents valuable assets. We rely on various intellectual property laws, confidentiality procedures and contractual provisions to protect our IP assets and enforce our IP rights. To optimize the value of our IP assets, we have engaged in licensing our design technology and other IP, including patents, when consistent with our competitive position and our customers’ interests. We have also entered into broad-scope cross-licenses and other agreements which enable us to design, manufacture and sell semiconductor products using the IP rights of third parties and/or operating within the scope of IP rights owned by third parties.

From time to time, we are involved in IP litigation and infringement claims. See Note 25 to our Consolidated Financial Statements and “Item 3. Key Information — Risk Factors”. Regardless of the validity or the successful assertion of such claims, we may incur significant costs with respect to the defense thereof, which could have a material adverse effect on our results of operations, cash flow or financial condition.

Backlog

Our sales are made primarily pursuant to standard purchase orders that are generally booked from one to twelve months in advance of delivery. Quantities actually purchased by customers, as well as prices, are subject to variations between booking and delivery and, in some cases, to cancellation due to changes in customer needs or industry conditions. During periods of economic slowdown and/or industry overcapacity and/or declining selling prices, customer orders are not generally made far in advance of the scheduled shipment date. Such reduced lead time can diminish management’s ability to forecast production levels and revenues. When the economy rebounds, our customers may strongly increase their demands, which can result in capacity constraints due to a time lag when matching manufacturing capacity with such demand.

In addition, our sales are affected by seasonality, with the first quarter generally showing lowest revenue levels in the year, and the third or fourth quarter historically generating higher amounts of revenues partly as a result of the seasonal dynamics for smartphone applications dynamics.

We also sell certain products to key customers pursuant to frame contracts. Frame contracts are annual contracts with customers setting forth quantities and prices on specific products that may be ordered in the future. These contracts allow us to schedule production capacity in advance and allow customers to manage their inventory levels consistent with just-in-time principles while shortening the cycle times required to produce

37

ordered products. Orders under frame contracts are also subject to a high degree of volatility, because they reflect expected market conditions which may or may not materialize. Thus, they are subject to risks of price reduction, order cancellation and modifications as to quantities actually ordered resulting in inventory build-ups.

Furthermore, developing industry trends, including customers’ use of outsourcing and their deployment of new and revised supply chain models, may reduce our ability to forecast changes in customer demand and may increase our financial requirements in terms of capital expenditures and inventory levels.

We entered 2023 with a backlog higher than we had entering 2022. For 2024, we entered the year with a backlog lower than what we had entering 2023.

Competition

Markets for our products are intensely competitive. We compete with major international semiconductor companies and while only a few companies compete with us in all of our product lines, we face significant competition from each of them. Smaller niche companies are also increasing their participation in the semiconductor market, and semiconductor foundry companies have expanded significantly, particularly in Asia. Competitors include manufacturers of standard semiconductors, ASICs and fully customized ICs, including both chip and board-level products, as well as customers who develop their own IC products and foundry operations. Some of our competitors are also our customers or suppliers. We compete in different product lines to various degrees on the basis of price, technical performance, product features, product system compatibility, customized design, availability, quality and sales and technical support. In particular, standard products may involve greater risk of competitive pricing, inventory imbalances and severe market fluctuations than differentiated products. Our ability to compete successfully depends on factors both within and outside our control, including successful and timely development of new products and manufacturing processes, product performance and quality, manufacturing yields and product availability, customer service, pricing, industry trends and general economic trends.

The semiconductor industry is characterized by the high costs associated with developing marketable products and manufacturing technologies as well as high levels of investment in production capabilities. As a result, the semiconductor industry has experienced, and is expected to continue to experience, significant vertical and horizontal consolidation among our suppliers, competitors and customers, which could lead to erosion of our market share, impact our capacity to compete and require us to restructure our operations. See “Item 3. Key Information — Risk Factors”.

Organizational Structure and History

We are organized in a matrix structure with geographic regions interacting with product lines, both supported by shared technology and manufacturing operations and by central functions, designed to enable us to be closer to our customers and to facilitate communication among the R&D, production, marketing and sales organizations.

While STMicroelectronics N.V. is the parent company, we conduct our global business through STMicroelectronics International N.V. and also conduct our operations through service activities from our subsidiaries.

Public Funding

We receive public funding mainly from EU member states (including France, Italy and Malta). Such funding is generally provided to encourage R&D activities, enhance building capacities, industrialization and national, regional and local economic development. On September 21, 2023, the European Chips Act entered into force. The regulation, mobilizing more than €43 billion of public and private investments, is designed to bolster Europe’s competitiveness and resilience in semiconductor technologies and applications, help achieve both the digital and green transition and has, amongst others, the objective of supporting technological capacity building and innovation in the European Union by bridging the gap between the European Union's advanced research and innovation capabilities and their industrial exploitation.

Public funding in Europe is also generally available to all companies having R&D operations in Europe, regardless of their ownership structure or country of incorporation. The conditions for the receipt of government funding may include eligibility restrictions, approval by EU authorities, annual budget appropriations, compliance with EU regulations, royalties or contingent return provisions as well as specifications regarding objectives and results. The approval process for such funding may last up to several years. Certain specific contracts require compliance with extensive regulatory requirements and set forth certain conditions relating to the funded programs. There could be penalties if these objectives are not fulfilled. Other contracts contain penalties for late deliveries or for breach of contract, which may result in repayment obligations.

Further, some grants may be subject to a financial return based on future cumulative sales over a certain period. Our funding programs are classified under four general categories: funding for Research and Development (R&D), Innovation activities (RDI), funding for First Industrial Deployment activities (FID) and capital investment for pilot lines. We also benefit from tax credits for R&D activities in several countries which are generally available to all companies. See “Item 5. Operating and Financial Review and Prospects — Results of Operations” and the Notes to our Consolidated Financial Statements.

The main programs in which we are involved include: (i) Important Project of Common European Interest (IPCEI) which combines Research, Development and Innovation activities (RDI) as well as First Industrials Deployment activities (FID); (ii) Key Digital Technologies Initiative (KDT), formerly Electronic Components and Systems for European Leadership (ECSEL), which combines all electronics related R&D activities and is operated by joint undertakings formed by the European Union, certain member states and industry; (iii) EU R&D projects within Horizon Europe (the European Union's research and innovation framework); and (iv) national or regional programs for R&D and for industrialization in the electronics industries involving many companies and laboratories. The pan-European programs cover a period of several years, while national or regional programs in France and Italy are subject mostly to annual budget appropriation.

In December 2018, the European Commission announced the approval of the IPCEI, a Pan-European project initiated to foster research and innovation in microelectronics to be funded by Germany, France, Italy, the U.K. and Austria.

In our combined role as beneficiary of the IPCEI on Microelectronics, we have been allocated an overall funding budget of €340 million for the period 2018-2022 in France (locally referenced as Nano2022) which was linked to technical objectives and associated achievements, and approximately €720 million for the period 2018-2024 in Italy. The IPCEI program is highly strengthening our leadership in key technologies. It contributes to anticipating, accelerating, and securing our technological developments. The IPCEI also has wide ranging, pan-European benefits on the microelectronics ecosystem from education to downstream industries.

In December 2021, we submitted a new IPCEI program, titled IPCEI on Microelectronics and Communication Technologies (IPCEI – ME/CT). This new pan-European project was initiated to foster research and innovation and kick-start the first industrialization of microelectronics. This new IPCEI involves ST in France (2022-2026), Italy (2023-2027) and Malta (2021-2025), as well as around 65 other companies across 16 European countries. In 2023 we recognized grants of €135 million related to our participation in IPCEI in Italy, €120 million related to our participation in IPCEI, KDT and other national and European programs in France and $9 million related to our participation in IPCEI in Malta.

In addition to public funding through IPCEI programs, in October 2022, the European Commission approved, under EU State Aid Rules, a support up to €292.5 million through the Italian Recovery and Resilience Plan for the construction of a new integrated silicon carbide substrate manufacturing facility in Catania, Italy.

On April 28, 2023, the European Commission approved, under EU State Aid Rules, a French aid measure to support the Company and GlobalFoundries in the construction and operation of a front-end semiconductor production facility in Crolles, France. This project represents an overall projected cost of €7.5 billion for capital expenditure, maintenance and ancillary costs. The new facility will benefit from significant financial support of up to roughly €2.9 billion from France. These projects have been recognized as “first-of-a-kind” facilities in Europe in line with the ambitions and objectives of the European Chips Act.

For more information on our Public Funding, see Note 7 to our Consolidated Financial Statements.

Suppliers

We use three primary critical types of suppliers in our business: (i) equipment suppliers, (ii) material suppliers and (iii) external silicon foundries and back-end subcontractors. We also purchase third-party licensed technology from a limited number of providers.

In the front-end process, we use steppers, scanners, tracking equipment, strippers, chemo-mechanical polishing equipment, cleaners, inspection equipment, etchers, physical and chemical vapor-deposition equipment, implanters, furnaces, testers, probers and other specialized equipment. The manufacturing tools that we use in the back-end process include bonders, burn-in ovens, testers and other specialized equipment. The quality and technology of equipment used in the IC manufacturing process defines the limits of our technology. Demand for increasingly smaller chip structures means that semiconductor producers must quickly incorporate the latest advances in process technology to remain competitive. Advances in process technology cannot occur without commensurate advances in equipment technology, and equipment costs tend to increase as the equipment becomes more sophisticated.

Our manufacturing processes consume significant amounts of energy and use many materials, including silicon and SiC, GaN and glass wafers, lead frames, mold compound, ceramic packages and chemicals, gases and water. The prices of energy, such as electricity and natural gas, and many of these materials are volatile due to the specificity of the market, and other factors including geopolitics. We have therefore adopted a “multiple sourcing strategy” designed to protect us from the risk of price increases. The same strategy applies to energy and to supplies for the materials used by us to avoid potential material disruption of essential materials and to ensure the continuity of energy supply. Our “multiple sourcing strategy”, our financial risk monitoring as well as the robustness of our supply chain and strong partnership with suppliers are intended to mitigate these risks. See “Item 3. Key Information — Risk Factors”.

Finally, we also use external subcontractors to outsource wafer manufacturing and assembly and testing of finished products. See “— Property, Plants and Equipment” above.

Environmental, Health and Safety Matters

We adopt a rigorous and pro-active approach to managing our business operations in an environmentally responsible way and are subject to a variety of environmental, health and safety laws and regulations in the jurisdictions where we operate. Such laws and regulations govern, among other things, the use, storage, discharge and disposal of chemicals and other hazardous substances, emissions and waste, as well as the investigation and remediation of soil and ground water contamination. We are also required to obtain environmental permits, licenses and other forms of authorization, or give prior notification, in order to operate.

Consistent with our sustainability strategy, we have established proactive environmental policies with respect to the handling of chemicals, emissions, waste disposals and other substances of concern from our manufacturing operations. We are certified to be in compliance with quality standard ISO 9001 on a Company-wide basis. We implement the highest standards across our manufacturing activities and supply chain. The majority of our manufacturing sites are ISO 14001 (environment), ISO 14064 (greenhouse gas emissions), and ISO 50001 (energy) certified and EMAS validated.

We believe that in 2023 our activities complied with then-applicable environmental regulations in all material respects. We have engaged outside consultants to audit all of our environmental activities and have created environmental management teams, information systems and training. We have also instituted

41

environmental control procedures for processes used by us as well as our suppliers. In 2023, there were no material environmental claims made against us.

On December 9, 2020, we announced our goal to become carbon neutral by 2027 on scope 1 and 2 and partially scope 3. Our comprehensive roadmap to carbon neutrality includes two specific targets: compliance with the 1.5°C scenario defined at the Paris COP21 by 2025, which implies a 50% reduction of direct and indirect greenhouse gas emissions compared to 2018, and the sourcing of 100% renewable energy by 2027. Our action plan will reduce:

(i)our direct emissions of greenhouse gases (scope 1), mainly through investment in equipment to burn the gases remaining after manufacturing;

(ii)our overall energy consumption (scope 2);

(iii)our emissions from product transportation, business travel, and employee commuting (part of scope 3); and

(iv)remaining emissions through the identification and implementation of the most credible and relevant carbon avoidance and sequestration programs.

We also adopt a rigorous approach to protect the health and safety of our employees and contractors by preventing work-related injuries and illnesses and providing a safe working environment.

We have implemented a robust health and safety management system throughout our Company. Our main manufacturing sites are ISO 45001 certified. Our performance and management systems are evaluated annually through third-party surveillance audits and certifications are renewed every three years.

On July 12, 2020, the EU Taxonomy Regulation entered into force. The EU Taxonomy Regulation provides the basis for the EU taxonomy: a classification system, on the basis of which a list of environmentally sustainable economic activities has been drawn up. The EU Taxonomy Regulation defines overarching conditions that an economic activity must meet to be considered environmentally sustainable, and focuses on six environmental objectives. On January 1, 2022 the delegated acts on the technical screening criteria for two environmental objectives, being Climate Change Mitigation and Adaption to Climate Change, entered into force, in which technical screening criteria have been laid down which specify environmental performance requirements for the economic activities to be classified as environmentally sustainable. The delegated acts on the technical screening criteria for the remaining four environmental objectives entered into force on 1 January 2024. As we are subject for our reporting over financial year 2023 to an obligation to publish non-financial information pursuant to Directive 2013/34/EU of the European Parliament and of the Council of June 26, 2013 on the annual financial statements, consolidated financial statements and related reports of certain types of undertakings, amending Directive 2006/43/EC of the European Parliament and of the Council and repealing Council Directives 78/660/EEC and 83/349/EEC (the Non-Financial Reporting Directive), the EU Taxonomy Regulation is applicable to us, and subsequently, we must disclose information on how and to what extent our activities are associated with economic activities that qualify as environmentally sustainable. This information will be disclosed in our Dutch Annual Report expected to be filed in March 2024.

On January 5, 2023, the CSRD entered into force. The CSRD modernizes and strengthens the rules about the social and environmental information that companies have to report. The CSRD aims to ensure that investors and other stakeholders have access to the information they need to assess investment risks arising from climate change and other sustainability topics. As of our reporting in relation to financial year 2024, the CSRD will require us to disclose information on the basis of European Sustainability Reporting Standards (“ESRS”) in our annual report. Based on the CSRD, we will be required to report on the way we operate and manage social and environmental challenges. In connection with these reporting obligations we will be required to formulate long-term ESG targets, policy, strategic plans and to conduct due diligence for our own operations and supply chain. Under the CSRD, further transparency rules are introduced on division of roles and responsibilities within the Company for our ESG targets. The CSRD also makes it mandatory for companies to have an audit of the sustainability information that they report. The ESRS require us to disclose detailed information on environmental protection, social responsibility and treatment of employees, respect for human rights, anti-corruption, bribery and on diversity. This information will be disclosed in our Dutch Annual Report starting from financial year 2024 expected to be filed in March 2025.

Item 5.    Operating and Financial Review and Prospects

Overview

The following discussion should be read in conjunction with our Consolidated Financial Statements and Notes thereto included elsewhere in this Form 20-F. The following discussion contains statements of future expectations and other forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, or Section 21E of the Securities Exchange Act of 1934, each as amended, particularly in the sections “— Critical Accounting Policies Using Significant Estimates”, “— Business Outlook”, “— Liquidity and Capital Resources” and “— Financial Outlook: Capital Investment”. Our actual results may differ significantly from those projected in the forward-looking statements. For a discussion of factors that might cause future actual results to differ materially from our recent results or those projected in the forward-looking statements in addition to the factors set forth below, see “Cautionary Note Regarding Forward-Looking Statements” and Item 3. “Key Information — Risk Factors”. We assume no obligation to update the forward-looking statements or such risk factors.

Critical Accounting Policies Using Significant Estimates

The preparation of our Consolidated Financial Statements in accordance with U.S. GAAP requires us to make estimates and assumptions. The primary areas that require significant estimates and judgments by us include, but are not limited to:

•sales allowances for discounts, price protection, product returns and other rebates;

•inventory obsolescence reserves and normal manufacturing capacity thresholds to determine costs capitalized in inventory;

•recognition and measurement of loss contingencies;

•valuation at fair value of assets acquired and liabilities assumed on business acquisitions, and measurement of any contingent consideration;

•annual and trigger-based impairment review of goodwill and intangible assets, as well as the assessment of events, which could trigger impairment testing on tangible assets;

•assessment of our long-lived assets economic useful lives;

•assumptions used in measuring expected credit losses and impairment charges on financial assets;

•assumptions used in assessing the number of awards expected to vest on stock-based compensation plans;

•assumptions used in calculating pension obligations and other long-term employee benefits; and

•determination of the amount of tax expected to be paid and tax benefit expected to be received, including deferred income tax assets, valuation allowance and provisions for uncertain tax positions and claims.

We base the estimates and assumptions on historical experience and on various other factors such as market trends, market information used by market participants and the latest available business plans that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. While we regularly evaluate our estimates and assumptions, the actual results we experience could differ materially and adversely from our estimates.

We believe the following critical accounting policies require us to make significant judgments and estimates in the preparation of our Consolidated Financial Statements:

Revenue recognition. Arrangements with customers are considered contracts if all the following criteria are met: (a) parties have approved the contract and are committed to perform their respective obligations; (b)

each party’s rights regarding the goods or services to be transferred can be identified; (c) payment terms for the goods or services to be transferred can be identified; (d) the contract has commercial substance and (e) collectability of substantially all of the consideration is probable. We recognize revenue from products sold to a customer, including distributors, when we satisfy a performance obligation by transferring control over a product to the customer. In certain circumstances, we may enter into agreements that concern principally revenues from services, where the performance obligation is satisfied over time. The objective when allocating the transaction price is to allocate the transaction price to each performance obligation (or distinct good or service) in an amount that depicts the amount of consideration to which we expect to be entitled in exchange for transferring the promised goods or services to the customer. The payment terms typically range between 30 to 90 days. Certain of our customers require us to hold inventory as consignment in their hubs and only purchase inventory when they require it. Revenue for sales of such inventory is recognized when, at the customer’s option, the products are withdrawn from the consignment and we satisfy a performance obligation by transferring control over a product to the customer. We may also enter into several multi-annual capacity reservation and volume commitment arrangements with certain of our customers. These agreements constitute a binding commitment for our customers to purchase and for us to supply allocated commitment volumes in exchange for additional consideration. The consideration related to commitment fees is reported as revenues from sale of products as it is usually based on delivered quantities.

Consistent with standard business practice in the semiconductor industry, price protection is granted to distribution customers on their existing inventory of our products to compensate them for changes in market prices. We accrue a provision for price protection based on a rolling historical price trend computed monthly as a percentage of gross distributor sales. This historical price trend represents differences in recent months between the invoiced price and the final price to the distributor, adjusted to accommodate a significant change in the selling price. The short outstanding inventory time, visibility into the inventory product pricing and long distributor pricing history have enabled us to reliably estimate price protection provisions at period-end. We record the accrued amounts as a deduction of “Net sales” in the consolidated statements of income at the time of the sale.

Our customers occasionally return our products for technical reasons. Our standard terms and conditions of sale provide that if we determine that products do not conform, we will repair or replace the non-conforming products, or issue a credit note or rebate of the purchase price. Quality returns are identified shortly after sale in customer quality control testing. Quality returns are usually associated with end-user customers, not with distribution channels. We record the accrued amounts as a deduction of “Net sales” in the consolidated statements of income, using contractual and historical information.

We record a provision for warranty costs as a charge against “Cost of sales” in the consolidated statements of income, based on historical trends of warranty costs incurred as a percentage of sales, which management had determined to be a reasonable estimate of the probable losses to be incurred for warranty claims in a period. Any potential warranty claims are subject to our determination that we are at fault for damages, and such claims must usually be submitted within a short period of time following the date of sale. This warranty is given in lieu of all other warranties, conditions or terms expressed or implied by statute or common law. Our contractual terms and conditions typically limit our liability to the sales value of the products that gave rise to the claims.

Our insurance policy relating to product liability covers third-party physical damages and bodily injury, indirect financial damages as well as immaterial non-consequential damages caused by defective products.

In addition to product sales, we enter into arrangements with customers consisting in transferring licenses or related to license services. The revenue generated from these arrangements is reported on the line “Other revenues” of the consolidated statements of income.

Trade accounts receivable. We use a lifetime expected credit losses allowance for all trade receivables. The allowance includes reasonable assumptions about future credit trends. The historical loss rates are adjusted to reflect current and forward-looking information on macro-economic factors affecting the ability of our customers to settle the receivables. Adjustments to the expected credit losses allowance are reported in the line “Selling, general and administrative expenses” in the consolidated statements of income.

Business combinations and goodwill. The acquisition method of accounting applied to business combinations requires extensive use of estimates and judgments to allocate the purchase price to the fair value of

44

acquired assets less assumed liabilities, including any contingent consideration, net of related deferred tax impacts. If the assumptions and estimates used to allocate the purchase price are not correct or if business conditions change, purchase price adjustments or future asset impairment charges could be required. As of December 31, 2023, the value of goodwill in our consolidated balance sheet amounted to $303 million.

Impairment of goodwill. Goodwill recognized in business combinations is not amortized but is tested for impairment annually, or more frequently if a triggering event indicating a possible impairment exists. Goodwill subject to potential impairment is tested at the reporting unit level. This impairment test determines whether the fair value of each reporting unit under which goodwill is allocated is lower than the total carrying amount of relevant net assets allocated to such reporting unit, including its allocated goodwill. A goodwill impairment charge is recorded for the amount by which a reporting unit’s carrying value exceeds its fair value. Significant management judgments and estimates are used in forecasting the future discounted cash flows associated with the reporting unit, including: the applicable industry’s sales volume forecast and selling price evolution, the reporting unit’s market penetration and its revenues evolution, the market acceptance of certain new technologies and products, the relevant cost structure, the discount rates applied using a weighted average cost of capital and the perpetuity rates used in calculating cash flow terminal values. Our evaluations are based on financial plans updated with the latest available projections of the semiconductor market, our sales expectations and our costs evolution, and are consistent with the plans and estimates that we use to manage our business. It is possible, however, that the plans and estimates used may prove to be incorrect, and future adverse changes in market conditions, changes in strategies, lack of performance of major customers or operating results of acquired businesses that are not in line with our estimates may require impairments.

We performed our annual impairment test of goodwill during the fourth quarter of 2023 and concluded that there was no goodwill impairment loss. Impairment charges could result from new valuations triggered by changes in our product portfolio or strategic alternatives, particularly in the event of a downward shift in future revenues or operating cash flows in relation to our current plans or in case of capital injections by, or equity transfers to, third parties at a value lower than the current carrying value.

Intangible assets subject to amortization. Intangible assets subject to amortization include intangible assets purchased from third parties recorded at cost and intangible assets acquired in business combinations initially recorded at fair value, comprised mainly of technologies and licenses, and computer software. Intangible assets with finite useful lives are reflected net of any impairment losses and are amortized over their estimated useful lives. Amortization begins when the intangible asset is available for its intended use. Amortization reflects the pattern in which the asset’s economic benefits are consumed, which usually consists in applying the straight-line method to allocate the cost of the intangible assets over the estimated useful lives. The carrying value of intangible assets with finite useful lives is evaluated whenever changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its fair value. We evaluate the remaining useful life of an intangible asset at each reporting date to determine whether events and circumstances warrant a revision to the remaining period of amortization. Our evaluations are based on financial plans updated with the latest available projections of growth in the semiconductor market and our sales expectations. They are consistent with the plans and estimates that we use to manage our business. It is possible, however, that the plans and estimates used may be incorrect and that future adverse changes in market conditions or operating results of businesses acquired may not be in line with our estimates and may therefore require us to recognize impairment charges on certain intangible assets.

In 2023 we recorded a $42 million impairment loss primarily related to technologies acquired as part of certain business combinations. In 2022, we impaired $38 million of certain technologies acquired as part of recent business combinations. In 2021, we impaired $1 million of acquired licenses and technologies with no alternative future use.

We will continue to monitor the carrying value of our assets. If market conditions deteriorate, this could result in future impairment losses. Further impairment charges could also result from new valuations triggered by changes in our product portfolio or by strategic transactions, particularly in the event of a downward shift in future revenues or operating cash flows in relation to our current plans or in case of capital injections by, or equity transfers to, third parties at a value lower than the one underlying the carrying amount.

As of December 31, 2023, the value of intangible assets subject to amortization in our consolidated balance sheet amounted to $367 million.

45

Property, plant and equipment. Our business requires substantial investments in technologically advanced manufacturing facilities, which may become significantly underutilized or obsolete as a result of rapid changes in demand and ongoing technological evolution. The largest component of our long-lived assets is our manufacturing equipment primarily in our front-end activities, for which the useful life is estimated to be six years, except for our 300mm manufacturing equipment and certain back-end equipment whose useful life is estimated to be ten years. This estimate is based on our experience using the equipment over time. Depreciation expense is an important element of our manufacturing cost structure. We begin to depreciate property, plant and equipment when it is ready for its intended use.

We evaluate each period whether there is reason to suspect that the carrying amount of tangible assets or groups of assets held for use might not be recoverable. Several impairment indicators exist for making this assessment, such as: restructuring plans, significant changes in the technology, market, economic or legal environment in which we operate, available evidence of obsolescence of the asset, or indication that its economic performance is, or will be, worse than expected. In determining the recoverability of assets to be held and used, we initially assess whether the carrying value of the tangible assets or group of assets exceeds the undiscounted cash flows associated with these assets. If exceeded, we then evaluate whether an impairment charge is required by determining if the asset’s carrying value also exceeds its fair value. We normally estimate this fair value based on independent market appraisals or the sum of discounted future cash flows, using market assumptions such as the utilization of our fabrication facilities and the ability to upgrade such facilities, change in the selling price and the adoption of new technologies. We also evaluate and adjust, if appropriate, the assets’ useful lives at each reporting date. In 2023, 2022 and 2021, no significant impairment charge was recorded on property, plant and equipment.

Our evaluations are based on financial plans updated with the latest projections of growth in the semiconductor market and our sales expectations, from which we derive the future production needs and loading of our manufacturing facilities, and which are consistent with the plans and estimates that we use to manage our business. These plans are highly variable due to the high volatility of the semiconductor business and therefore are subject to continuous modifications. If future growth differs from the estimates used in our plans, in terms of both market growth and production allocation to our manufacturing plants, this could require a further review of the carrying amount of our tangible assets and result in a potential impairment loss.

As of December 31, 2023, we did not hold any significant assets for sale.

Inventories. Inventories are stated at the lower of cost or net realizable value. Actual cost is based on an adjusted standard cost, which approximates cost on a first-in first-out basis for all categories of inventory (raw materials, work-in-process, finished products). Actual cost is therefore dependent on our manufacturing performance and is based on the normal utilization of our production capacity. In case of underutilization of our manufacturing facilities, we estimate the costs associated with unused capacity. These costs are not included in the valuation of inventories but are charged directly to cost of sales in the consolidated statements of income. Net realizable value is based upon the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation.

Inventory reserve is estimated for excess uncommitted inventories based on historical sales data, order backlog and production plans. We perform, on a continuous basis, write-offs of inventories, which have the characteristics of slow-moving, old production dates and technical obsolescence. We evaluate inventory to identify obsolete or slow-selling items, as well as inventory that is not of saleable quality and we record a specific reserve if we estimate the inventory will eventually be written off. To the extent that future negative market conditions generate order backlog cancellations and declining sales, or if future conditions are less favorable than the projected revenue assumptions, we could record additional inventory reserve, which would have a negative impact on our gross margin.

Share-based compensation. Our share-based service awards are granted to senior executives and selected employees. We measure the cost of share-based service awards based on the fair value of the awards as of the grant date reflecting the market price of the underlying shares at the date of the grant, reduced by the present value of the dividends expected to be paid on the shares during the requisite service period. While the awards granted to selected employees are subject to a three-year service period, the awards granted to senior executives are subject to both a three-year service period and the fulfillment of certain performance conditions, including our financial results when compared to industry performance. The expense is recognized over the requisite service period. In 2023, approximately one-half of the total amount of shares awarded were granted to senior

46

executives and consequently were contingent on the achievement of performance conditions. In order to determine share-based compensation to be recorded for the period, we use estimates on the number of awards expected to vest, including the probability of achieving the fixed performance conditions including those relating to our financial results compared to industry performance, and our best estimates of award forfeitures and employees’ service periods. Our assumptions related to industry performance are generally taken with a one quarter lag in line with the availability of market information. In 2023, 2022 and 2021, we recorded a total charge of approximately $236 million, $215 million and $221 million relating to our outstanding stock award plans, respectively.

Financial assets. The financial assets held at reporting date are primarily receivables, debt securities and equity securities. Receivables are measured at amortized cost less any currently expected credit loss allowance. Investments in equity securities that have readily determinable fair values and for which we do not have the ability to exercise significant influence are classified as financial assets measured at fair value through earnings. For investments in equity securities without readily determinable fair values and for which we do not have the ability to exercise significant influence, we have elected to apply the cost-method as a measurement alternative. We determine the classification of our financial assets at initial recognition.

The fair values of publicly traded securities are based on current market prices. If the market for a financial asset is not active and if no observable market price is obtainable, we measure fair value by using assumptions and estimates. In measuring fair value, we make maximum use of market inputs and minimize the use of unobservable inputs.

Debt securities are classified as-available-for-sale financial assets, with changes in fair value recognized as a component of other comprehensive income in our consolidated statements of comprehensive income. Debt securities totaled $1,635 million and were reported as marketable securities in the consolidated balance sheet as of December 31, 2023.

As of December 31, 2023, we did not hold any material equity securities reported under the equity method.

Income taxes. We make estimates and judgments in determining income tax for the period, comprising current and deferred income tax. We assess the income tax expected to be paid related to the current year taxable profit in each tax jurisdiction and recognize deferred income tax for all temporary differences arising between the tax bases of assets and liabilities and their carrying amount in the Consolidated Financial Statements. We also recognize deferred tax assets on temporary differences arising from tax losses carried forward and tax credits. Furthermore, at each reporting date, we assess all material uncertain tax positions in all jurisdictions to determine the amount of income tax benefits that we do not expect to reasonably sustain. As of December 31, 2023, we had uncertain tax positions estimated at $55 million.

We also assess the likelihood of realization of our deferred tax assets. Their ultimate realization is dependent upon, among other things, our ability to generate future taxable profit available, or tax credits before their expiration, or our ability to implement prudent and feasible tax planning, or the possibility to settle uncertain tax positions against available net operating loss carry forwards, or similar tax losses and credits. We record a valuation allowance against the deferred tax assets when we consider it is more likely than not that the deferred tax assets will not be realized.

As of December 31, 2023, we had deferred tax assets of $592 million, net of valuation allowance.

We could be required to record further valuation allowances thereby reducing the amount of total deferred tax assets, resulting in an increase in our income tax charge, if our estimates of projected future taxable income and benefits from available tax strategies are reduced as a result of a change in business conditions or in management’s plans or due to other factors, or if changes in current tax regulations are enacted that impose restrictions on the timing or extent of our ability to utilize net operating losses and tax credit carry-forwards in the future. Likewise, a change in the tax rates applicable in the various jurisdictions or unfavorable outcomes of any ongoing tax audits could have a material impact on our future tax provisions in the periods in which these changes could occur.

Pension and Post-Employment Benefits. Our consolidated statements of income and our consolidated balance sheets include amounts for pension obligations and other long-term employee benefits that are measured

47

using actuarial valuations. As of December 31, 2023, our pension and other long-term employee benefit obligations net of plan assets amounted to $453 million. These valuations are based on key assumptions, including discount rates, expected long-term rates of return on plan assets, turnover rates and salary increase rates. The assumptions used in the determination of the net periodic benefit cost are updated on an annual basis at the beginning of each fiscal year or more frequently upon the occurrence of significant events. Any changes in the pension schemes or in the above assumptions can have an impact on our valuations. The measurement date we use for our plans is December 31.

Patent and other IP litigation or claims. We record a provision when we believe that it is probable that a liability has been incurred at the date of the Consolidated Financial Statements and the amount of the loss can be reasonably estimated. We regularly evaluate losses and claims to determine whether they need to be adjusted based on current information available to us. Such estimates are difficult to the extent that they are largely dependent on the status of ongoing litigation that may vary based on positions taken by the court with respect to issues submitted, demands of opposing parties, changing laws, discovery of new facts or other matters of fact or law. As of December 31, 2023, based on our current evaluation of ongoing litigation and claims we face, we have not estimated any amounts that could have a material impact on our results of operations and financial condition with respect to either probable or possible risks. In the event of litigation that is adversely determined with respect to our interests, or in the event that we need to change our evaluation of a potential third-party claim based on new evidence, facts or communications, unexpected rulings or changes in the law, this could have a material adverse effect on our results of operations or financial condition at the time it were to materialize. We are in discussion with several parties with respect to claims against us relating to possible infringement of IP rights. We are also involved in certain legal proceedings concerning such issues. See “Item 8. Financial Information — Legal Proceedings” and Note 25 to our Consolidated Financial Statements.

Other claims. We are subject to the possibility of loss contingencies arising in the ordinary course of business. These include but are not limited to: product liability claims and/or warranty costs on our products, contractual disputes, indemnification claims, employee grievances, tax claims beyond assessed uncertain tax positions as well as claims for environmental damages. We are also exposed to numerous legal risks which until now have not resulted in legal disputes and proceedings. These include risks related to product recalls, environment, anti-trust, anti-corruption and competition as well as other compliance regulations. We may also face claims in the event of breaches of law committed by individual employees or third parties. In determining loss contingencies, we consider the likelihood of a loss of an asset or the occurrence of a liability, as well as our ability to reasonably estimate the amount of such loss or liability. An estimated loss is recorded when we believe that it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. We regularly re-evaluate any losses and claims and determine whether our provisions need to be adjusted based on the current information available to us. As of December 31, 2023, based on our current evaluation of ongoing litigation and claims we face, we have not estimated any amounts that could have a material impact on our results of operations and financial condition with respect to either probable or possible risks. In the event we are unable to accurately estimate the amount of such loss in a correct and timely manner, this could have a material adverse effect on our results of operations or financial condition at the time such loss was to materialize. For further details of our legal proceedings refer to “Item 8. Financial Information — Legal Proceedings” and Note 25 to our Consolidated Financial Statements.

Fiscal Year 2023

Under Article 35 of our Articles of Association, our financial year extends from January 1 to December 31, which is the period end of each fiscal year. In 2023, the first quarter ended on April 1, the second quarter ended on July 1, the third quarter ended on September 30 and the fourth quarter ended on December 31. In 2024, the first quarter will end on March 30, the second quarter will end on June 29, the third quarter will end on September 28 and the fourth quarter will end on December 31. Based on our fiscal calendar, the distribution of our revenues and expenses by quarter may be unbalanced due to a different number of days in the various quarters of the fiscal year and can also differ from equivalent prior years’ periods, as illustrated in the below table for the years 2022, 2023 and 2024.

Our total available market is defined as “TAM”, while our serviceable available market is defined as “SAM” and represents the market for products sold by us (i.e., TAM excluding major devices such as microprocessors, DRAM and flash-memories, optoelectronics devices other than optical sensors, video processing and wireless application specific market products, such as baseband and application processors).

Based on industry data published by WSTS, semiconductor industry revenues in 2023 decreased on a year-over-year basis by approximately 8% for the TAM and increased by approximately 4% for the SAM, to reach approximately $527 billion and $295 billion, respectively. In the fourth quarter of 2023, on a year-over-year basis, the TAM increased by approximately 12% and the SAM increased by approximately 8%. Sequentially, the TAM increased by approximately 8% and the SAM increased by approximately 2%.

Full year 2023 net revenues increased 7.2% to $17.29 billion; gross margin was 47.9% and operating margin was 26.7%.

Our fourth quarter net revenues amounted to $4,282 million, decreasing 3.2% year-over-year, gross margin was 45.5%, and operating margin was 23.9%. On a sequential basis, fourth quarter net revenues decreased 3.4%, 40 basis points lower than the mid-point of our guidance. On a sequential basis, ADG reported an increase in net revenues, AMS was stable and MDG decreased.

Our quarterly performance was below the SAM on a sequential and a year-over-year basis.

Our effective average exchange rate was $1.08 for €1.00 for the full year 2023, as compared to $1.10 for €1.00 for the full year 2022. Our effective average exchange rate for the fourth quarter of 2023 was $1.08 for €1.00, compared to $1.09 for €1.00 for the third quarter of 2023 and $1.04 for €1.00 in the fourth quarter of 2022. For a more detailed discussion of our hedging arrangements and the impact of fluctuations in exchange rates, see “Impact of Changes in Exchange Rates”.

Our 2023 gross margin increased 60 basis points to 47.9% from 47.3% in 2022, principally driven by the positive impact of the combination of product mix and pricing, partially offset by higher input manufacturing costs and unused capacity charges.

49

Our fourth quarter 2023 gross profit was $1,949 million and gross margin was 45.5%, 50 basis points below the mid-point of our guidance, mainly due to a less favorable product mix. On a sequential basis, gross margin decreased by 210 basis points mainly due to a less favorable product mix, negative sales price impact, and higher unused capacity charges. On a year-over-year basis, gross margin decreased 200 basis points, due to higher input manufacturing costs, unused capacity charges, and negative currency effect net of hedging, partially offset by the combination of sales price and product mix.

Our operating expenses, comprised of aggregated selling, general & administrative (“SG&A”) and research & development (“R&D”) expenses, amounted to $3,731 million in 2023, increasing by 11.2% from $3,355 million in the prior year, mainly due to increased cost of labor and higher levels of activity, primarily in R&D programs, partially offset by positive currency effects. On aggregate, R&D and SG&A expenses were $937 million for the fourth quarter of 2023, compared to $926 million and $850 million in the prior and year-ago quarters, respectively. The sequential increase was mainly due to seasonality associated with lower vacation days. The year-over-year increase of operating expenses was mainly due to higher cost of labor, negative currency effects and higher levels of activity, primarily in R&D programs.

Other income and expenses, net, were $55 million in 2023 compared to $159 million in 2022, decreasing mainly due to higher start-up costs primarily for our new 300mm fab in Agrate, Italy, partially offset by higher income from public funding. Fourth quarter other income and expenses, net, were $11 million, compared to $58 million in the prior quarter and $35 million in the year-ago quarter. The sequential decrease was mainly due to lower income from public funding. The year-over-year decrease was principally driven by higher start-up costs.

Operating income in 2023 was $4,611 million, increasing by $172 million compared to 2022, mainly driven by the combining effect of higher revenues and improved gross margin profitability, partially offset by higher operating expenses.

Operating income in the fourth quarter decreased on a sequential and year-over-year basis to $1,023 million compared to $1,241 million and $1,287 million in the prior and year-ago quarter, respectively. The sequential decrease was mainly due to lower gross profit and decreased R&D funding. The year-over-year decrease was mainly due to lower revenues, decreased gross margin profitability and higher operating expenses.

Full year 2023 net income was $4,211 million, or $4.46 diluted earnings per share, compared to net income of $3,960 million, or $4.19 diluted earnings per share for the full year 2022. Fourth quarter net income increased on a sequential and year-over-year basis to $1,076 million, or $1.14 diluted earnings per share, compared to net income of $1,090 million, or $1.16 diluted earnings per share, in the prior quarter, and a net income of $1,248 million, or $1.32 diluted earnings per share, in the year-ago quarter.

During 2023, our net cash from operating activities was at $5,992 million. Our net cash used in investing activities was at $5,766 million with capital expenditure payments, net of proceeds from sales, capital grants and other contributions at $798 million and $4,111 million during the fourth quarter and full year 2023, respectively, compared to $920 million and $3,524 million for the fourth quarter and full year 2022 respectively.

Our free cash flow, a non-U.S. GAAP measure, amounted to $1,774 million in 2023 compared to $1,591 million in 2022. Refer to “Liquidity and Capital Resources” for the reconciliation of the free cash flow, a non-U.S. GAAP measure, to our consolidated statements of cash flows.

During 2023, we received $329 million of proceeds from long-term debt and used $346 million for the repurchase of common stock, $223 million of dividends paid to our shareholders and $169 million for long-term debt repayment.

Business Outlook

Our first quarter 2024 outlook reflects revenues of approximately $3.6 billion at the mid-point, decreasing year-over-year by 15.2%, and decreasing on a sequential basis by 15.9%, plus or minus 350 basis points. Gross margin is expected to be at approximately 42.3%, plus or minus 200 basis points. For 2024, we plan to invest about $2.5 billion in net capital expenditures.

We will drive the Company based on a plan for 2024 revenues in the range of $15.9 billion to $16.9 billion. Within this plan we expect a gross margin in the low to mid-40's.

50

This outlook is based on an assumed effective currency exchange rate of approximately $1.09 = €1.00 for the 2024 first quarter and includes the impact of existing hedging contracts. The first quarter will close on March 30, 2024.

These are forward-looking statements that are subject to known and unknown risks and uncertainties that could cause actual results to differ materially; in particular, refer to those known risks and uncertainties described in “Cautionary Note Regarding Forward-Looking Statements” and “Item 3.

Results of Operations

Segment Information

We design, develop, manufacture and market a broad range of products, including discrete and standard commodity components, ASICs, full-custom devices and semi-custom devices and ASSPs for analog, digital and mixed-signal applications. In addition, we further participate in the manufacturing value chain of smartcard products, which includes the production and sale of both silicon chips and smartcards.

As of December 31, 2023, our reportable segments were as follows:

•Automotive and Discrete Group (ADG), comprised of dedicated automotive integrated circuits (“ICs”), and discrete and power transistor products.

•Analog, MEMS and Sensors Group (AMS), comprised of analog, smart power, MEMS sensors and actuators, and optical sensing solutions.

•Microcontrollers and Digital ICs Group (MDG), comprised of general-purpose microcontrollers and microprocessors, connected security products (e.g. embedded secured elements and NFC readers), memories (e.g. serial and page EEPROM) and RF and Communications products.

Net revenues of “Others” include revenues from sales assembly services and other revenues. For the computation of the segments’ internal financial measurements, we use certain internal rules of allocation for the costs not directly chargeable to the segments, including cost of sales, SG&A expenses and a part of R&D expenses. In compliance with our internal policies, certain costs are not allocated to the segments, but reported in “Others”. Operating income (loss) of Others includes items such as unused capacity charges, including reduced manufacturing activity due to COVID-19 and incidents leading to power outage, impairment, restructuring charges and other related closure costs, management reorganization expenses, start-up and phase-

out costs, and other unallocated income (expenses) such as: strategic or special R&D programs, certain corporate-level operating expenses, patent claims and litigations, and other costs that are not allocated to product groups, as well as operating earnings of other products. In addition, depreciation and amortization expense is part of the manufacturing costs allocated to the segments and is neither identified as part of the inventory variation nor as part of the unused capacity charges; therefore, it cannot be isolated in cost of sales. Finally, public grants are allocated to our segments proportionally to the incurred expenses on the sponsored projects..

Wafer costs are allocated to the segments based on actual cost. From time to time, with respect to specific technologies, wafer costs are allocated to segments based on market price.

In the first quarter of 2024, we announced that we are re-organizing our product groups and reportable segments to further accelerate our time-to-market and the efficiency of our product development. Effective as of February 5, 2024, we have moved from three product groups and three reportable segments (ADG, AMS and MDG), to two product groups and four reportable segments, as follows:

•Analog, Power & Discrete, MEMS and Sensors, led by Marco Cassis, ST President and member of the Executive Committee, including two reportable segments (Analog Products, MEMS and Sensors (and Power and Discrete Products; and

•Microcontrollers, Digital ICs and RF products, led by Remi El-Ouazzane, ST President and member of the Executive Committee, including two reportable segments (Microcontrollers and Digital ICs and RF Products.

	(In millions)
Interest income (expense), net	$	171	$	58	$	(29)

In 2023, we recorded a net interest income of $171 million, compared to net interest income of $58 million and a net interest expense of $29 million in 2022 and 2021, respectively. In 2023, net interest income was composed of $226 million of interest income, offset by interest expense on borrowings and banking fees of $55 million. In 2022, net interest income was composed of $71 million of interest income, partially offset by interest expense on borrowings and banking fees of $13 million.

Interest expense includes the financial cost of the convertible bonds issued by the Company in 2020. On January 1, 2022, we adopted the new U.S. GAAP reporting guidance on distinguishing liabilities from equity and EPS, by applying the modified retrospective method, under which prior year periods are not restated. Interest expense recorded in 2021 included a charge of $34 million related to the outstanding senior unsecured convertible bonds, mainly resulting from the non-cash accretion expense, as recorded under the previous accounting guidance. With the adoption of the new guidance, the finance cost of the convertible debt instruments outstanding at the date of adoption is limited to the amortization expense of debt issuance costs. The amortization expense of debt issuance costs amounted to $1 million for the year ended December 31, 2023, $1 million for the year ended December 31, 2022 and $3 million for the year ended December 31, 2021.

In 2021, interest expense on our borrowings and banking fees amounted to $42 million, of which $34 million was a non-cash interest expense resulting from the accretion of the liability component of our senior unsecured convertible bonds. The interest expense was partially offset by $13 million of interest income on cash and cash equivalents, short-term deposits and marketable securities.

Income tax expense	$	(541)	$	(520)	$	(331)

In 2023, we registered an income tax expense of $541 million, compared to $520 million in 2022 and $331 million in 2021. These amounts reflect the actual taxes calculated on our income before income taxes in each of our jurisdictions and tax benefits, net of valuation allowances, associated with our estimates of the net operating loss realization, in certain jurisdictions, against future taxable profits, one-time tax benefits related to previous year positions and our best estimate of additional tax charges related to potential uncertain tax positions and claims.

In 2023, the effective tax rate was 15%, before $174 million of tax benefit from discrete items, which included a one-time non-cash income tax benefit of $191 million.

In 2022, the effective tax rate was 15%, before $133 million of tax benefit from discrete items, which included a one-time non-cash income tax benefit of $140 million.

In 2021, the effective tax rate was 15%, before $17 million of tax benefit from discrete items.

Our tax rate is variable and depends on changes in the level of operating results within various local jurisdictions and on changes in the taxation rates applicable in these jurisdictions, as well as changes in estimates and assumptions used when assessing our tax positions. Our income tax amounts and rates depend also on our loss carry-forwards and their relevant valuation allowances, which are based on estimated projected plans and available tax planning; in the case of material changes to these plans, the valuation allowances could be adjusted accordingly with an impact on our income tax expense (benefit). We currently enjoy certain tax benefits in some countries. Such benefits may not be available in the future due to changes in the local jurisdictions; our effective tax rate could be different in future periods and may increase in the coming years. In

addition, our yearly income tax expense includes the estimated impact of provisions related to income tax positions which have been considered as uncertain.

Diluted earnings per share for the years 2023 and 2022 included the full dilutive effect of our outstanding convertible debt upon adoption of the newly applicable U.S. GAAP reporting guidance on January 1, 2022. Prior year period has not been restated.

Quarterly Results of Operations

Certain quarterly financial information for the years 2023 and 2022 are set forth below. Such information is derived from our unaudited Consolidated Financial Statements, prepared on a basis consistent with the audited Consolidated Financial Statements that include, in our opinion, all normal adjustments necessary for a fair statement of the interim information set forth therein. Operating results for any quarter are not necessarily indicative of results for any future period. In addition, in view of the significant volatility we have experienced in recent years, the increasingly competitive nature of the markets in which we operate, the changes in products mix and the currency effects of changes in the composition of sales and production among different geographic regions, we believe that period-to-period comparisons of our operating results should not be relied upon as an indication of future performance.

Our quarterly and annual operating results are also affected by a wide variety of other factors that could materially and adversely affect revenues and profitability or lead to significant variability of operating results, please see “Item 3. Key Information — Risk Factors — Risks Related to Our Operations”. As only a portion of our expenses varies with our revenues, there can be no assurance that we will be able to reduce costs promptly or adequately in relation to revenue declines to compensate for the effect of any such factors. As a result, unfavorable changes in the above or other factors have in the past and may in the future adversely affect our operating results. Quarterly results have also been and may be expected to continue to be substantially affected by the cyclical nature of the semiconductor and electronic systems industries, the speed of some process and manufacturing technology developments, market demand for existing products, the timing and success of new product introductions and the levels of provisions and other unusual charges incurred. Certain additions of our quarterly results will not total our annual results due to rounding.

Impact of Changes in Exchange Rates

Our results of operations and financial condition can be significantly affected by material changes in the exchange rates between the U.S. dollar and other currencies, particularly the Euro.

As a market practice, the reference currency for the semiconductor industry is the U.S. dollar and the market prices of semiconductor products are mainly denominated in U.S. dollars. However, revenues for some of our products are quoted in currencies other than the U.S. dollar, such as Euro-denominated sales, and consequently are directly affected by fluctuations in the value of the U.S. dollar. As a result of currency variations, the appreciation of the Euro compared to the U.S. dollar could increase our level of revenues when translated into U.S. dollars or the depreciation of the Euro compared to the U.S. dollar could decrease our level of revenues when reported in U.S. dollars. Over time and depending on market conditions, the prices in the industry could align to the equivalent amount in U.S. dollars, except that there is a lag between the changes in

64

the currency rate and the adjustment in the price paid in local currency, which is proportional to the amplitude of the currency swing, and such adjustment could be only partial and/or delayed, depending on market demand. Furthermore, certain significant costs incurred by us, such as manufacturing costs, SG&A expenses, and R&D expenses, are largely incurred in the currency of the jurisdictions in which our operations are located. Given that most of our operations are located in the Eurozone and other non-U.S. dollar currency areas, including Singapore, our costs tend to increase when translated into U.S. dollars when the U.S. dollar weakens or to decrease when the U.S. dollar strengthens.

Our principal strategy to reduce the risks associated with exchange rate fluctuations is to balance as much as possible the proportion of sales to our customers denominated in U.S. dollars with the amount of materials, purchases and services from our suppliers denominated in U.S. dollars, thereby reducing the potential exchange rate impact of certain variable costs relative to revenues. Moreover, in order to further reduce the exposure to U.S. dollar exchange fluctuations, we hedge certain line items on our consolidated statements of income, in particular with respect to a portion of cost of sales, most of R&D expenses and certain SG&A expenses, located in the Eurozone, which we designate as cash flow hedge transactions. We use two different types of hedging instruments: forward contracts and currency options (including collars).

Our consolidated statements of income included income and expense items translated at the average U.S. dollar exchange rate for the period, plus the impact of the hedging contracts expiring during the period. Our effective average exchange rate was $1.08 for €1.00 for the full year 2023 and $1.10 for €1.00 for the full year 2022. Our effective exchange rate was $1.08 for €1.00 for the fourth quarter of 2023, $1.09 for €1.00 for the third quarter of 2023 and $1.04 for €1.00 for the fourth quarter of 2022. These effective exchange rates reflect the actual exchange rates combined with the effect of cash flow hedge transactions impacting earnings in the period.

The time horizon of our cash flow hedging for manufacturing costs and operating expenses may run up to 24 months, for a limited percentage of our exposure to the Euro, depending on currency market circumstances. As of December 31, 2023, the outstanding hedged amounts were €1,591 million to cover manufacturing costs and €685 million to cover operating expenses, at an average exchange rate of approximately $1.10 for €1.00 (considering the collars at upper strike), maturing from January 4, 2024 to January 6, 2025. As of December 31, 2023, measured in respect to the exchange rate at period closing of about $1.10 to €1.00, these outstanding hedging contracts and certain settled contracts covering manufacturing expenses capitalized in inventory resulted in a deferred gain of approximately $54 million before tax, recorded in “Accumulated other comprehensive income” in the consolidated statements of equity, compared to a deferred gain of approximately $17 million before tax as of December 31, 2022.

We also hedge certain manufacturing costs denominated in Singapore dollars (SGD); as of December 31, 2023, the outstanding hedged amounts were SGD 219 million at an average exchange rate of about SGD 1.33 to $1.00 maturing over the period from January 4, 2024 to November 27, 2024. As of December 31, 2023, the deferred gain of these outstanding hedging contracts were $3 million, compared to deferred gain of approximately $6 million before tax as of December 31, 2022.

Our cash flow hedging policy is not intended to cover our full exposure and is based on hedging a declining portion of our exposure in the next four quarters. In 2023, as a result of our cash flow hedging, we recycled to earnings a gain of $5 million, composed of a $1 million gain impacting cost of sales, a $3 million gain impacting R&D and a $1 million gain impacting SG&A expenses. In 2022, as a result of our cash flow hedging, we recycled to earnings a loss of $197 million, composed of a $129 million loss impacting cost of sales, a $53 million loss impacting R&D and $15 million loss impacting SG&A expenses.

In addition to our cash flow hedging, in order to mitigate potential exchange rate risks on our commercial transactions, we purchase and enter into foreign exchange forward contracts and currency options to cover foreign currency exposure in payables or receivables at our affiliates, which we do not designate for hedge accounting. We may in the future purchase or sell similar types of instruments. See “Item 11. Quantitative and Qualitative Disclosures About Market Risk” in our Form 20-F. Furthermore, we may not predict on a timely basis the amount of future transactions in the volatile industry environment. No assurance may be given that our hedging activities will sufficiently protect us against fluctuations in the value of the U.S. dollar. Consequently, our results of operations have been and may continue to be impacted by fluctuations in exchange rates. The net effect of our consolidated foreign exchange exposure in payables and receivables at our affiliates resulted in a

65

net gain of $5 million recorded in “Other income and expenses, net” in our 2023 consolidated statement of income compared to a net gain of $15 million and $7 million in 2022 and 2021, respectively.

The assets and liabilities of subsidiaries whose functional currency is different from the U.S. dollar reporting currency are, for consolidation purposes, translated into U.S. dollars at the period-end exchange rate. Income and expenses, as well as cash flows, are translated at the average exchange rate for the period. The balance sheet impact, as well as the income statement and cash flow impact, of these currency translations have been, and may be, significant from period to period since a large part of our assets and liabilities and activities are accounted for in Euros as they are located in jurisdictions where the Euro is the functional currency. Adjustments resulting from the currency translation are recorded directly in equity and are reported as “Accumulated other comprehensive income” in the consolidated statements of equity. As of December 31, 2023, our outstanding indebtedness was denominated mainly in U.S. dollars and in Euros.

For a more detailed discussion, see “Item 3. Key Information — Risk Factors — Risks Related to Our Operations”.

Impact of Changes in Interest Rates

Interest rates may fluctuate upon changes in financial market conditions and material changes can affect our results of operations and financial condition, since these changes can impact the total interest income received on our cash and cash equivalents, short-term deposits and marketable securities, as well as the total interest expense paid on our financial debt.

Our interest income (expense), net, as reported in our consolidated statements of income, is the balance between interest income received from our cash and cash equivalents, short-term deposits and marketable securities and interest expense recorded on our financial liabilities, including bank fees (including fees on committed credit lines or on the sale without recourse of receivables, if any). Our interest income is dependent upon fluctuations in interest rates, mainly in U.S. dollars and Euros, since we invest primarily on a short-term basis; any increase or decrease in the market interest rates would mean a proportional increase or decrease in our interest income. Our interest expenses are also dependent upon fluctuations in interest rates since our financial liabilities include European Investment Bank (“EIB”) and Cassa Depositi e Prestiti SpA (“CDP SpA”) Floating Rate Loans at Euribor plus variable spreads. See Note 15 to our Consolidated Financial Statements.

As of December 31, 2023, our total financial resources, including cash and cash equivalents, short-term deposits and marketable securities, generated an average annual interest rate of 5.11%. At the same date, the average annual interest rate on our outstanding debt was 2.20%.

A rise in interest rates to address inflation or otherwise will also impact the base rates applicable in our credit arrangements and will result in borrowed funds becoming more expensive to us over time. These financing and inflationary pressures may also reduce disposable income on a macro-economic basis, eroding the values of savings, and could have a negative impact on our customers’ ability to purchase our products in the same volumes.

Impact of Changes in Equity Prices

As of December 31, 2023, we did not hold any significant investments in equity securities with a material exposure to equity price risk. However, on these equity investments, carrying value could be reduced due to further losses or impairment charges. See Note 12 and Note 13 to our Consolidated Financial Statements.

Liquidity and Capital Resources

Treasury activities are regulated by our policies, which define procedures, objectives and controls. Our policies focus on the management of our financial risk in terms of exposure to currency rates and interest rates. Most treasury activities are centralized, with any local treasury activities subject to oversight from our head treasury office. The majority of our cash and cash equivalents are held in U.S. dollars and Euros and are placed with financial institutions rated at least as single A long-term rating from two of the major rating agencies, meaning at least A3 from Moody’s Investors Service (“Moody’s”) and A- from Standard & Poor’s (“S&P”) or Fitch Ratings (“Fitch”). Marginal amounts are held in other currencies. See “Item 11. Quantitative and Qualitative Disclosures About Market Risk”.

66

Our total liquidity was $6,083 million as of December 31, 2023, increasing compared to $4,518 million as of December 31, 2022. As of December 31, 2023, our total liquidity was comprised of $3,222 million in cash and cash equivalents, $1,226 million in short-term deposits and $1,635 million in marketable securities, all classified as current assets.

As of December 31, 2023, marketable securities were $1,635 million invested in U.S. Treasury Bonds, with a rating of Aaa/AA+/AA+ from Moody’s, S&P and Fitch, respectively, and a weighted average maturity of 1.6 years. The securities are classified as available-for-sale and reported at fair value. This fair value measurement corresponds to a Level 1 fair value hierarchy measurement. To optimize the return yield on our short-term investments, we also held $1,226 million of available cash in short-term deposits as of December 31, 2023. These short-term deposits represent liquidity with maturity beyond three months and below one year with no significant risk of changes in fair value.

Cash flow

We maintain an adequate cash position and a low debt-to-equity ratio to provide us with adequate financial flexibility. As in the past, our cash management policy is to finance our investment needs mainly with net cash from operating activities.

During 2023, our cash and cash equivalents decreased by $36 million. The components of the net cash decrease for 2023 and the comparable periods are set forth below:

	Year Ended December 31,
	2023		2022		2021
	(In millions)
Net cash from operating activities	$	5,992	$	5,202	$	3,060
Net cash used in investing activities	$	(5,766)	$	(4,591)	$	(1,518)
Net cash used in financing activities	$	(267)	$	(567)	$	(1,314)
Effect of changes in exchange rates	$	5	$	(11)	$	(9)
Net cash increase (decrease)	$	(36)	$	33	$	219

Net cash from operating activities. Net cash from operating activities is the sum of (i) net income adjusted for non-cash items and (ii) changes in net working capital. The net cash from operating activities in 2023 was $5,992 million compared to $5,202 million in the prior year, increasing mainly due to higher net income adjusted for non-cash items.

Net cash used in investing activities. Investing activities used $5,766 million in 2023, increasing from $4,591 million in the prior year, mainly due to increased payments for net purchase of tangible assets which totaled $4,111 million compared to $3,524 million in the prior year, higher purchases of marketable securities and net investment in short-term deposits, partially offset by proceeds from marketable securities. Capital investments for the year 2023 included (i) investments in advanced wafer fabs, such as the 300mm fab in Crolles, France and the 300mm fab in Agrate, Italy; (ii) SiC activities, primarily in Singapore and Catania, Italy; and (iii) in selected programs of capacity growth in other front-end and back-end activities.

Net cash used in financing activities. Net cash used in financing activities was $267 million in 2023, compared to net cash used in financing activities of $567 million in 2022, and consisted mainly of $346 million repurchase of common stock, $223 million of dividends paid to our stockholders and $169 million repayment of long-term debt, partially offset primarily by $329 million of proceeds from a new drawdown from our existing credit facility with EIB.

Free Cash Flow (non-U.S. GAAP measure). We also present Free Cash Flow, which is a non-U.S. GAAP measure, defined as (i) net cash from operating activities plus (ii) net cash used in investing activities, excluding payment for purchase of (and proceeds from matured) marketable securities, and net investment in (and proceeds from) short-term deposits, which are considered as temporary financial investments. This definition ultimately results in net cash from operating activities plus payment for purchase (and proceeds from sale) of tangible, intangible and financial assets, proceeds from capital grants and other contributions, and net cash paid for business acquisitions, if any.

67

We believe Free Cash Flow provides useful information for investors and management because it measures our capacity to generate cash from our operating and investing activities to sustain our operations. Free Cash Flow does not represent total cash flow since it does not include the cash flows from, or used in, financing activities.

Free Cash Flow reconciles with the total cash flow and the net cash increase (decrease) by including the payment for purchases of (and proceeds from matured) marketable securities and net investment in (and proceeds from) short-term deposits, the net cash from (used in) financing activities and the effect of changes in exchange rates. Our definition of Free Cash Flow may differ from definitions used by other companies. Free Cash Flow is determined from our unaudited interim consolidated statements of cash flows as follows:

	Year Ended December 31,
	2023		2022		2021
	(In millions)
Net cash from operating activities	$	5,992	$	5,202	$	3,060
Payment for purchase of tangible assets, net of proceeds from sale and proceeds from capital grants and other contributions	$	(4,111)	$	(3,524)	$	(1,828)
Payment for purchase of intangible assets, net of proceeds from sale	$	(97)	$	(87)	$	(97)
Payment for purchase of financial assets, net of proceeds from sale	$	(10)	$	—	$	(15)
Free Cash Flow (non-U.S. GAAP measure)(1)	$	1,774	$	1,591	$	1,120

(1)    Free Cash Flow can also be expressed as Net cash from operating and investing activities, excluding cash from (used in) marketable securities and short-term deposits.

In 2023, we had a positive Free Cash Flow of $1,774 million, compared to positive $1,591 million and positive $1,120 million in 2022 and 2021, respectively.

Capital Resources

Net Financial Position and Adjusted Net Financial Position (non-U.S. GAAP measures). Our Net Financial Position represents the difference between our total liquidity and our total financial debt. Our total liquidity includes cash and cash equivalents, short-term deposits and marketable securities, and our total financial debt includes short-term debt and long-term debt, as reported in our consolidated balance sheets. Adjusted Net Financial Position represents net financial position less advances from capital grants, to present the effect on total liquidity of advances received on capital grants for which capital expenditures have not been incurred yet. Prior periods are not impacted. Net Financial Position and Adjusted Net Financial Position are not U.S. GAAP measures, but we believe they provide useful information for investors and management because they give evidence of our global position either in terms of net indebtedness or net cash by measuring our capital resources based on cash and cash equivalents, restricted cash, if any, short-term deposits and marketable securities and the total level of our financial debt. Our definition of Net Financial Position may differ from definitions used by other companies and therefore comparability may be limited. Our Net Financial Position and Adjusted Net Financial Position for each period have been determined from our consolidated balance sheets as follows:

68

	Year Ended December 31,
	2023		2022		2021
	(In millions)
Cash and cash equivalents	$	3,222	$	3,258	$	3,225
Short-term deposits	$	1,226	$	581	$	291
Marketable securities	$	1,635	$	679	$	—
Total liquidity	$	6,083	$	4,518	$	3,516
Short-term debt	$	(217)	$	(175)	$	(143)
Long-term debt	$	(2,710)	$	(2,542)	$	(2,396)
Total financial debt	$	(2,927)	$	(2,717)	$	(2,539)
Net Financial Position	$	3,156	$	1,801	$	977
Advances from capital grants	$	(152)	$	—	$	—
Adjusted Net Financial Position	$	3,004	$	1,801	$	977

Our Net Financial Position as of December 31, 2023 was a net cash position of $3,156 million, increasing compared to a net cash position of $1,801 million as of December 31, 2022.

Cash and cash equivalents amounted to $3,222 million as of December 31, 2023.

Short-term deposits amounted to $1,226 million as of December 31, 2023 and consisted of available liquidity with maturity over three months and below one year.

Marketable securities amounted to $1,635 million as of December 31, 2023 and consisted of U.S. Treasury Bonds classified as available-for-sale.

Financial debt was $2,927 million, as of December 31, 2023 and was composed of (i) $217 million of short-term debt and (ii) $2,710 million of long-term debt. The breakdown of our total financial debt included (i) $1,077 million in EIB loans, (ii) $284 million in CDP SpA loans, (iii) $1,496 million in our 2020 Senior Unsecured Convertible Bonds, (iii) $65 million in finance leases and, (iv) $5 million in loans from other funding programs.

The EIB loans are comprised of three long-term amortizing credit facilities as part of R&D funding programs. The first one, signed in August 2017, is a €500 million loan in relation to R&D and capital expenditures in the European Union for the years 2017 and 2018. The entire amount was fully drawn in Euros corresponding to $303 million outstanding as of December 31, 2023. The second one, signed in 2020, is a €500 million credit facility agreement with EIB to support R&D and capital expenditure programs in Italy and France. The amount was fully drawn in Euros representing $442 million outstanding as of December 31, 2023. In 2022, the Company signed a third long-term amortizing credit facility with EIB of €600 million, out of which, €300 million was withdrawn representing $332 million outstanding as of December 31, 2023. In January 2024, an amount of $300 million was withdrawn under this credit facility.

The CDP SpA loans are comprised of two long-term credit facilities. The first, signed in 2021, is a €150 million loan, fully drawn in Euros, of which $97 million were outstanding as of December 31, 2023. The second one, signed in 2022, is a €200 million loan, fully drawn in Euros, of which $187 million was outstanding as of December 31, 2023.

On August 4, 2020, we issued a $1.5 billion principal amount of dual tranche senior unsecured convertible bonds (Tranche A and Tranche B for $750 million each tranche), due 2025 and 2027, respectively. Tranche A bonds were issued at 105.8% as zero-coupon bonds while Tranche B bonds were issued at 104.5% as zero-coupon bonds. The conversion price at issuance was $43.62 for Tranche A equivalent to a 47.5% conversion premium and $45.10 for Tranche B, equivalent to a 52.5% conversion premium. These conversion features correspond to an equivalent of 4,585 shares per each Tranche A bond $200,000 par value and an equivalent of 4,435 shares per each Tranche B bond $200,000 par value. The bonds are convertible by the bondholders or are callable by the issuer upon certain conditions, on a net-share settlement basis, except if the issuer elects a full-cash or full-share conversion as an alternative settlement. The net proceeds from the bond offering were $1,567 million, after deducting issuance costs paid by the Company.

69

As of December 31, 2023, our stock price exceeded the conversion price of the senior unsecured convertible bonds. However, the 130% stock price contingent feature was not met. Consequently, Tranche A bonds are not callable by us and bondholders cannot exercise their conversion rights on Tranche B bonds.

Our long-term debt contains standard conditions but does not impose minimum financial ratios. We had unutilized committed medium-term credit facilities with core relationship banks totaling $1,030 million as of December 31, 2023.

As of December 31, 2023, debt payments at principal amount by period were as follows:

	Payments Due by Period
	Total		2024		2025		2026		2027		2028		Thereafter
	(In millions)
Long-term debt (including    current portion)	$	2,931	$	217	$	962	$	212	$	947	$	198	$	395

Our 2020 Senior Unsecured Convertible Bonds are presented at their principal amount with original maturity date of 2025 for Tranche A and 2027 for Tranche B, in line with contractual terms.

Our current ratings with the two major rating agencies that report on us on a solicited basis, are as follows: S&P: “BBB+” with stable outlook; Moody’s: “Baa1” with positive outlook.

Contractual Obligations, Commercial Commitments and Contingencies

Our contractual obligations, commercial commitments and contingencies as of December 31, 2023, and for each of the five years to come and thereafter, were as follows:(1)

	Total		2024		2025		2026		2027		2028		Thereafter

(1)    Contingent liabilities which cannot be quantified are excluded from the table above.

(2)    Items not reflected on the consolidated balance sheet as of December 31, 2023.

(3)    Items reflected on the consolidated balance sheet as of December 31, 2023.

(4)    For long-term debt obligations the difference between the total obligations and the total carrying amount of long-term debt is due to the unamortized debt issuance costs on the dual tranche senior unsecured convertible bonds. See Note 15 to our Consolidated Financial Statements as of December 31, 2023 for additional information related to long-term debt.

(5)    For other long-term liabilities, the difference with the amount reported on the consolidated balance sheet as of December 31, 2023 is related to the long-term portion of the operating lease obligation of $188 million reported under the “Lease obligations” line. See Note 11 and Note 17 to our Consolidated Financial Statements as of December 31, 2023 for additional information related to leases and other long-term liabilities.

70

Purchase and other obligations are primarily comprised of purchase commitments for outsourced foundry wafers and firm contractual commitments related to power purchase and minimum energy efficiency, as part of our actions to become carbon neutral by 2027 on scope 1 and 2 and partially scope 3.

Long-term debt obligations mainly consist of bank loans and senior unsecured convertible bonds. In the table above, our 2020 Senior Unsecured Convertible Bonds are presented at their principal amount with original maturity date of 2025 for Tranche A and 2027 for Tranche B, in line with contractual terms. In 2024 we expect to repay with available cash and cash equivalents an amount of $205 million related to our loans with the European Investment Bank and CDP SpA through annual and semi-annual installments respectively and $10 million related to our finance leases. See “— Net financial position (non-U.S. GAAP measure)” above.

Pension obligations amounting to $372 million consist of our best estimates of the amounts projected to be payable by us for the pension and post-employment plans. The final actual amount to be paid and related timing of such payments may vary significantly due to early retirements, terminations and changes in assumptions rates. See Note 16 to our Consolidated Financial Statements.

Other long-term liabilities mainly include future obligations related to other long-term employees benefits, contingent consideration on business combinations and other contractual obligations. In accordance with the authoritative guidance for accounting for uncertainty in income taxes, as of December 31, 2023, liabilities related to uncertain tax positions totaled $55 million. See Note 23 of our Consolidated Financial Statements.

Off-Balance Sheet Arrangements

We had no material off-balance sheet arrangements as of December 31, 2023.

Financial Outlook: Capital Investment

Our policy is to modulate our capital spending according to the evolution of the semiconductor market. For 2024, we plan to invest about $2.5 billion in net capital expenditures.

A large portion of capital expenditures will be devoted to support our strategic programs, selected capacity additions and mix change in our manufacturing footprint, in particular for our wafer fabs:

•the increase capacity for silicon carbide products in our Catania and Singapore fabs;

•the ramp-up of a new integrated silicon carbide substrate manufacturing facility in Catania for the production in volume of 150mm, moving to 200mm, silicon carbide epitaxial substrates;

•the creation of new 200mm silicon carbide device manufacturing joint venture with Sanan Optoelectronics in Chongqing, China;

•the ramp-up of our new 300mm wafer fab in Agrate, Italy, to support mixed signal technologies and then phase-in smart power technologies and embedded-non-volatile memory at a later stage;

•digital 300mm in Crolles, France, to extend the cleanroom and support production ramp-up of our main runner technologies;

•certain selected programs of capacity growth in some of our most advanced 200mm fabs, including the analog 200mm fab in Singapore.

The most important 2024 capital investments for our back-end facilities will be: (i) capacity growth on certain package families, including PLP / Direct Copper Interconnect technology and automotive related packages, (ii) the new generation of Intelligent Power Modules for Automotive and Industrial applications, and (iii) specific investments in innovative assembly processes and test operations.

The remaining part of our capital investment plan covers the overall maintenance and efficiency improvements of our manufacturing operations and infrastructure, R&D activities, laboratories as well as the execution of our carbon neutrality programs.

Capital expenditures are net of proceeds from sales, capital grants and other contributions.

71

We will continue to invest to support revenues growth and new products introduction, taking into consideration factors such as trends in the semiconductor industry, capacity utilization and our goal to become carbon neutral by 2027 on scope 1 and 2 and partially scope 3. We expect to need significant financial resources in the coming years for capital expenditures and for our investments in manufacturing and R&D. We plan to fund our capital requirements with cash provided by operating activities, available funds and support from third parties, and may have recourse to borrowings under available credit lines and, to the extent necessary or attractive based on market conditions prevailing at the time, the issuance of debt, convertible bonds or additional equity securities. A substantial deterioration of our economic results, and consequently of our profitability, could generate a deterioration of the cash generated by our operating activities. Therefore, there can be no assurance that, in future periods, we will generate the same level of cash as in prior years to fund our capital expenditure plans for expanding/upgrading our production facilities, our working capital requirements, our R&D and manufacturing costs.

We believe that we have the financial resources needed to meet our currently projected business requirements for the next twelve months, including capital expenditures for our manufacturing activities, working capital requirements, approved dividend payments, share buy-backs as part of our current repurchase program and the repayment of our debt in line with maturity dates.

We will drive the Company based on a plan for 2024 revenues in the range of $15.9 billion to $16.9 billion. Within this plan, we expect a gross margin in the low to mid-40's.

80

appointed on May 27, 2021 for a subsequent three-year term expiring at the 2024 AGM and is currently the sole member of the Managing Board with the function of President and Chief Executive Officer. Our Supervisory Board announced on September 19, 2023, that it will propose the reappointment of Mr. Jean-Marc Chery as sole member of the Managing Board, President and Chief Executive Officer for another three-year term for shareholder approval at the 2024 AGM. We continue to review and strengthen the succession planning for the Managing Board to ensure business continuity, taking into account, amongst others, the rapidly changing technological, social, economic and regulatory developments in our industry. For further biographical details concerning the sole member of the Managing Board, our President and Chief Executive Officer, please refer to the “Biographies of our Executive Committee members (including the President and Chief Executive Officer)” section.

Under our Articles of Association, Managing Board members are appointed for a three-year term upon a non-binding proposal by our Supervisory Board at our AGM and adoption by a simple majority of the votes cast at the AGM, provided quorum conditions are met, which term may be renewed one or more times.

Our shareholders’ meeting may suspend or dismiss one or more members of our Managing Board, in accordance with the procedures laid down in our Articles of Association. Under Dutch law, our Managing Board is entrusted with our general management and the representation of the Company. Our Managing Board must seek prior approval from our shareholders’ meeting for decisions regarding a significant change in the identity or nature of the Company. Under our Articles of Association and our Supervisory Board charter, our Managing Board must also seek prior approval from our Supervisory Board for certain other decisions with regard to the Company and our direct or indirect subsidiaries.

The sole member of our Managing Board may not serve on the board of a public company without the prior approval of our Supervisory Board. Pursuant to the Supervisory Board charter, the sole member of our Managing Board must inform our Supervisory Board of any (potential) conflict of interest and pursuant to such charter and Dutch law, any Managing Board resolution regarding a transaction in relation to which the sole member of our Managing Board has a conflict of interest must be approved and adopted by our Supervisory Board. Should our entire Supervisory Board also have a conflict of interest, the resolution must be adopted by our shareholders’ meeting pursuant to Dutch law. We are not aware of any actual or potential conflicts of interests between the private interest or other duties of the sole member of our Managing Board and members of our Senior Management and their duties to us.

Pursuant to our Articles of Association and the Supervisory Board charter, the following decisions by our Managing Board with regard to the Company and any of our direct or indirect subsidiaries (an “ST Group Company”) require prior approval from our Supervisory Board: (i) any modification of our or any ST Group Company’s Articles of Association or other constitutional documents, other than those of wholly owned subsidiaries; (ii) other than for wholly owned subsidiaries, any change in our or any ST Group Company’s authorized share capital or any issue, acquisition or disposal by us — with the exception of shares in our share capital acquired in order to transfer these shares under employee stock option or stock purchase plans — or any ST Group Company of own shares or change in share rights and any issue of instruments resulting in a share in performance conditions related to corporate social responsibility and environmental, social and governance factors. Both short-term and long-term incentive includes performance conditions promoting ST’s sustainable growth.

ii.Managing Board compensation

a.Guiding principles of Managing Board compensation

Amongst others, the following key principles are considered by the Supervisory Board to determine the remuneration structure of the sole member of the Managing Board, our President and Chief Executive Officer:

•Alignment with the Company’s strategy: the compensation package should be strongly linked to the achievement of targets that are indicators of the execution of the Company’s business strategy.

•Improving the performance of the Company: most of the compensation (excluding base salary, benefits, and pensions) is directly linked to the Company’s performance through variable pay incentives. These incentives are based on ambitious performance conditions that include a mix of internal and external criteria as well as relative performance conditions against peers.

81

•Enhancing long-term creation of shareholder value: to strengthen the alignment with the interests of the shareholders and to enhance the long-term value creation of the Company, the compensation structure includes short-term and long-term variable remuneration either in cash or in shares or a combination thereof.

•Promoting sustainable corporate development: to ensure that the Company is managed in a sustainable and responsible manner for the common good, the remuneration includes non-financial performance conditions related to corporate social responsibility and environmental, social, and governance factors. Both short- and long-term incentive include performance conditions promoting ST’s sustainable growth.

•Retaining and motivating key employees: the compensation package should be competitive, ensuring remuneration levels are determined by reference internally between the Company’s senior managers and externally against the Peer Group.

In accordance with the key principles of the Company’s remuneration structure, the total remuneration of the sole member of the Managing Board, our President and Chief Executive Officer takes into consideration factors such as the size and complexity of our Company, our global presence and that of our customers, the pace of change in our industry, the Company’s value proposition, strategy and goal of long-term value creation, and the need to recruit and retain key personnel.

b.Managing Board remuneration policy

The remuneration of the sole member of the Managing Board, our President and Chief Executive Officer, is determined by our Supervisory Board on the advice of the Compensation Committee.

In compliance with the disclosure requirements in the Dutch Civil Code, we present in this Item 6 comparative information on our performance relative to the compensation of the members of our Senior Management and the sole member of the Managing Board, our President and Chief Executive Officer.

The Compensation Committee advises the Supervisory Board in reviewing the remuneration package of the sole member of the Managing Board, our President and Chief Executive Officer both in the context of the Company performance and against the Peer Group and relevant market index. Before setting targets for the sole member of the Managing Board, our President and Chief Executive Officer, the Compensation Committee carries out scenario analyses of the possible financial outcomes of meeting target levels.

Set forth in the table below is the list of companies retained for the Peer Group compensation analysis used for the remuneration policy for the Managing Board:

Analog Devices	ON Semiconductor
Infineon	Texas Instruments
Monolithic Power Systems	Vishay
Microchip	Rohm
NXP Semiconductors	Renesas

Should one of the Peer Group companies not publish financial results for any reason, Diodes and/or Melexis would replace the missing company.

The remuneration of the sole member of the Managing Board, our President and Chief Executive Officer, is bound by the remuneration policy as adopted by our 2021 AGM for a duration of a maximum of 4 years. Under the terms of the Dutch Civil Code, the remuneration policy for the Managing Board shall be submitted to the AGM for adoption at least every four years after its adoption. A resolution to adopt the remuneration policy requires a majority of at least 75% of the votes cast. At the 2023 AGM, over 92% of voting shareholders voted in favor of the remuneration report.

The remuneration policy for the Managing Board contains the following key features:

•the reinforcement of the link between Managing Board remuneration and long-term company strategy;

82

•the simplification of the short-term incentive structure (fully paid in cash, as compared to a hybrid cash-equity pay-out previously) featuring enhanced disclosure of criteria and threshold, targets, and maximum performance levels;

•the inclusion of corporate social responsibility criteria among performance conditions for both the short-term and long-term incentive in line with our objectives of promoting sustainable corporate development;

•enhanced disclosure of long-term incentive (share-settled) performance conditions and threshold and target performance levels as well as the remaining outstanding shares (which are not yet vested);

•a three-year performance period for long-term incentives (as compared to one year previously), with vesting based on performance measured over the 3-year performance period, to improve alignment of Managing Board remuneration with our objective of enhancing long-term shareholder value;

•enhanced disclosure regarding early vesting provisions for the unvested stock awards;

•the implementation of share ownership guidelines for the Managing Board; and

•claw-back provisions in order to reclaim payments after they have been awarded or to withhold remuneration under specific conditions.

c.Managing Board remuneration structure

The remuneration structure is reflective of the level of responsibility of the Company’s sole member of the Managing Board, our President and Chief Executive Officer. The remuneration structure is further aligned to the Company’s current context while remaining competitive and providing an incentive to promote the Company’s performance over the medium to long-term, and is in line with the Company’s corporate interest and the interests of all its stakeholders.

The Supervisory Board, upon proposal from the Compensation Committee, determines the remuneration structure and remuneration amounts for the sole member of the Managing Board, our President and Chief Executive Officer based on the analysis of the theoretical maximum total direct remuneration (i.e., sum of base salary, maximum short-term incentive, and maximum long-term incentive).

The remuneration package of the sole member of the Managing Board, our President and Chief Executive Officer is comprised of the following:

•A base salary; and

•Variable components, linked to performance:

oA short-term incentive of up to 210% of base salary which is fully paid in cash.

oA long-term incentive through the grant of stock awards, up to a maximum of 100,000 shares.

The sum of these three elements represents the maximum total direct remuneration for the sole member of the Managing Board, our President and Chief Executive Officer.

The above-mentioned three elements of the total maximum remuneration of the sole member of the Managing Board, our President and Chief Executive Officer are further described below:

Base salary

The purpose of the base salary is to provide a fixed level of earnings and to attract and retain the sole member of the Managing Board, our President and Chief Executive Officer. It is a key component of overall remuneration, particularly as the short-term incentive is expressed as a percentage of base salary. The Company seeks to determine a fair and competitive base salary as compared to the Peer Group based on several factors.

Short-term incentive

83

The purpose of the short-term incentive is to motivate the sole member of the Managing Board, our President and Chief Executive Officer to achieve financial and commercial objectives consistent with and supportive of the Company’s strategy and to create a tangible link between annual performance and individual pay opportunity.

In accordance with the Managing Board remuneration policy and effective from the year 2021, the short-term incentive of the sole member of the Managing Board, our President and Chief Executive Officer is fully paid in cash up to a maximum of 210% of the base salary for the relevant year, all subject to the assessment and achievement of a number of performance conditions which are set annually by the Compensation Committee of our Supervisory Board.

The short-term incentive is subject to annual performance measurement of a unique set of 4 to 7 predefined criteria (both financial and non-financial) and a performance matrix both for financial and non-financial criteria that explicitly outline threshold and target outcomes (as well as overperformance conditions for financial criteria).

Performance measures and weightings are reviewed annually by the Compensation Committee. The recommendations made by the Compensation Committee regarding scorecard targets and weightings are designed to support the delivery of the Company’s strategy. The Supervisory Board, upon recommendation by the Compensation Committee, retains the ability to adjust performance measure targets and weightings year-by-year within the overall target and maximum pay-outs approved in the remuneration policy.

The Supervisory Board, upon the recommendation of its Compensation Committee, sets the conditions and performance criteria that must be met by the sole member of the Managing Board, our President and Chief Executive Officer for the attribution of his short-term incentive (which is paid in the subsequent year).

These performance conditions will enable the Supervisory Board to conduct a holistic and comprehensive assessment of the annual performance of the sole member of the Managing Board, our President and Chief Executive Officer. The combination of financial and non-financial criteria is well balanced in terms of external and internal criteria and reflect the challenging objectives set by the Compensation Committee in line with the Company's ambitious long-term vision and business strategy.

The financial performance criteria for 2023, as chosen by the Supervisory Board were as follows:

•Market share evolution, which is measured by assessing the Company’s relative positioning and competitiveness in relation to its market and its industry peers and how fast the Company grows its revenues compared to its competitors. Market share is assessed on the basis of industry data published by WSTS.

•Revenue growth, which represents the total amount of income generated by the Company’s operations;

•Operating income, which is an important yardstick of profit measurement and reflects the operating performance of the business which does not take into consideration of non-operating gains or losses suffered by business, the impact of financial leverage and tax factors; and

•Net operating cash flow, which is a liquidity metric that evaluates whether the Company has enough liquidity to meet its debt obligations. This metric helps assess the financial soundness of the company in terms of liquidity risk, financial risk, credit risk and business risk.

The non-financial performance criteria for 2023, as chosen by the Supervisory Board were as follows:

•Execution of special manufacturing programs, including our new 300mm fab in Agrate, Italy, and wide-band gap capacity expansion notably in SiC (with notably our new integrated SiC substrate manufacturing facility in Catania, Italy, and the increase in capacity for SiC products in our Catania, Italy, and Singapore fabs);

•Execution of strategy implementation; and

•Sustainability/corporate social responsibility index, which is divided into four criteria related to:

oHealth & safety: measured against, amongst others, the employee safety performance;

84

oEnvironment/climate: measured against, amongst others, direct emissions (kCO2 equivalent);

oDiversity & inclusion: measured against, amongst others, gender ratio among management levels; and

oPeople management: measured against, amongst others, the employee survey (engagement index).

The weight of the sustainability/corporate social responsibility index is designed to remain stable over time, however the individual sub-components used to form the sustainability/corporate social responsibility index may evolve in the future to address sustainability priorities facing the Company and society.

Set forth in the following Table A1 and Chart A1 is the weight set for 2023 for each of the performance criteria that will be assessed by the Supervisory Board in March 2024 for the attribution of the 2023 short-term incentive (to be paid in 2024):

Table A1: Performance criteria with target weighting and pay-out

Annual short-term incentive performance criteria financial year 2023 (to be paid in 2024)	Target Weighting (as a % of total weighting for performance criteria)	Target pay-out (as a % of base salary)
Financial performance conditions
o  Market share evolution	14%	30%
o  Revenue growth	19%	40%
o  Operating income	19%	40%
o  Net operating cash flow	19%	40%
Sub-total for financial performance conditions	71%	150%
Non-financial performance conditions
o   Execute special manufacturing programs	14%	30%
o   Execute strategy implementation	5%	10%
o   Sustainability/corporate social responsibility index	10%	20%
Sub-total for non-financial performance conditions	29%	60%
Total	100%	210%

85

Chart A1: Performance criteria with target weighting and pay-out

As described in Table A2 below, the final pay-out of the short-term incentive is calculated by measuring the performance of each condition, then adding the sums of the corresponding pay-out from Table A1 above, taking into account any applicable caps. The sum is then multiplied by the base salary to determine the final short-term incentive pay-out.

Table A2: Pay-out according to performance for each performance criterion

	Pay-out as a percentage of base salary
Annual short-term incentive performance criteria financial year 2023 (to be paid in 2024)	Performance below threshold	Performance above or equal to threshold and below target	Performance above or equal to target and below stretch	Performance above stretch
Financial performance conditions
oMarket share evolution	0%	15%	30%	45%
oRevenue growth	0%	20%	40%	60%

___________________________

(1)     Over-performance for financial conditions can balance the potential under-performance of other financial conditions if performance exceeds stretch targets, without exceeding a maximum pay-out of 150% of base salary regarding the portion of the short-term incentive dependent on financial performance criteria.

(2)     No stretch targets are defined for non-financial performance criteria.

As of the publication of this Form 20-F the evaluation and assessment of the fulfillment of conditions and performance criteria as well as the determination of conditions for the 2023 short-term incentive have not yet been completed by the Supervisory Board upon the proposal of the Compensation Committee (expected in March 2024).

As a result, performance achievement levels and final pay-out for the short-term incentive based on 2023 performance (to be paid in 2024), as well as the scorecard for the 2023 short-term incentive will be disclosed at a later date, and is expected to be included in the 2023 Dutch Annual Report. Scorecard targets are not disclosed prospectively as it would require the disclosure of commercially sensitive information. Scorecard targets for the 2023 short-term incentive will be disclosed only when they are no longer deemed to be commercially sensitive.

Long-term incentive

The purpose of the long-term incentive is to motivate the sole member of the Managing Board, our President and Chief Executive Officer to deliver sustainable long-term shareholder value through long-term profitability and share price growth.

The terms of this long-term incentive are included in the long-term incentive plan approved at the 2021 AGM, allowing for grants of unvested stock awards in 2021, 2022 and 2023. The vesting of unvested stock awards is subject to the achievement of performance conditions and calculated over a three-year performance period. Grants of unvested stock awards made in 2022 and 2023 will fully vest, subject to performance conditions, in 2025 and 2026 respectively.

Award levels are determined annually by the Compensation Committee within the maximum amounts set by the Supervisory Board. In accordance with the resolution adopted by our AGM, the maximum annual grant allowed in relation to the sole member of the Managing Board, our President and Chief Executive Officer’s stock award for 2021, 2022 and 2023 was 100,000 unvested stock awards subject to performance criteria.

The Supervisory Board, upon recommendation of the Compensation Committee, determines whether the performance criteria are met and concludes whether and to which extent the sole member of the Managing Board, our President and Chief Executive Officer, is entitled to any stock awards under the long-term incentive plan. Scorecard targets are not disclosed prospectively as it would require the disclosure of commercially sensitive information. Scorecard targets will be disclosed only when they are no longer deemed to be commercially sensitive.

Grants in 2023, 2022 and 2021

In accordance with the long-term incentive plan approved at the 2021 AGM, allowing for grants in 2021, 2022 and 2023, the stock awards vest at the end of a three-year performance period, from the date of the grant, provided that the sole member of the Managing Board, our President and Chief Executive Officer is still an employee at such time (subject to the termination provisions listed below in “Section f. Compensation provisions in the event of termination or departure of the sole member of the Managing Board, our President and Chief Executive Officer”).

For the 2023 long-term incentive, the performance criteria are:

•Revenue growth;

•Operating margin; and

•Sustainability/corporate social responsibility index, which was comprised of the following KPIs (including two external criteria):

oEnvironment/climate: measured against, amongst others, the direct emissions (kCO2 equivalent);

87

oDiversity, inclusion and people engagement: measured against, amongst others, gender ratio among management levels;

oInvestor ESG index: measured against, amongst others, the Dow Jones sustainability indices; and

oCarbon rating: measured against, amongst others, the CDP carbon rating.

Set forth in the following Table B1 and Chart B1 is the weight set for each of the performance criteria that will be assessed by the Supervisory Board over the three performance periods for the attribution of the relevant long-term incentive.

Table B1: Long-term incentive performance criteria and target weighting over the three performance periods

iv.Senior Management compensation

a.Guiding principles of Senior Management compensation

The Managing Board determines the remuneration structure of the Senior Management based on, amongst others, the same key principles that the Supervisory Board considers when determining the remuneration structure of the Managing Board. These key principles are described above in “section B.ii.a Guiding principles of Managing Board compensation”.

In accordance with the key principles, the total remuneration of the Senior Management takes into consideration factors such as the size and complexity of the Company, our global presence and that of our customers, the pace of change in our industry, the Company’s value proposition, strategy and goal of long-term value creation, and the need to recruit and retain key personnel.

b.Senior Management remuneration structure

The Managing Board determines the remuneration structure and remuneration amounts for our Senior Management based on the analysis of the theoretical maximum total direct remuneration (i.e., sum of base salary, maximum short-term incentive, and maximum long-term incentive).

The remuneration package of the Senior Management is comprised of the following:

•Base salary; and

•Variable components, linked to performance:

oA short-term incentive which is fully paid in cash.

oA long-term incentive through the grant of stock awards, that are included in the long-term incentive plan approved at the AGM.

The sum of these three elements represents the maximum total direct remuneration for the Senior Management.

104

Base salary

The purpose of the base salary is to provide a fixed level of earnings and to attract and retain talent. It is a key component of overall remuneration, particularly as the short-term incentive is expressed as a percentage of base salary.

Short-term incentive

The short-term incentive based on the corporate executive incentive program (“EIP”), entitles selected executives, including the members of Senior Management, to an annual short-term incentive. This short-term incentive is based upon the assessment of the achievement of individual, organizational and Company objectives that are set on an annual basis and focused on, inter alia, return on net assets, customer service, profit, cash flow and market share. The maximum amount awarded under the short-term incentive is based upon a percentage of the executive’s salary and the overall achievement of the relevant objectives on an annual basis.

The 2023 short-term incentive includes a sustainability/corporate social responsibility index for Senior Management, as part of our efforts to include corporate social responsibility into the performance framework of our Senior Management. For Executive Committee members and Executive Vice Presidents, the weight of the sustainability/corporate social responsibility index ranges between 5% and 10%. The sustainability/corporate social responsibility index is divided into four criteria related to health and safety, environment, diversity & inclusion, and people engagement.

For the 2023 short-term incentive, the sustainability/corporate social responsibility index was comprised of the following KPIs:

•Health & safety: measured against, amongst others, the employee safety performance

•Environment/climate: measured against, amongst others, direct emissions (kCO2 equivalent)

•Diversity & inclusion: measured against, amongst others, gender ratio among management levels

•People management: measured against, amongst others, the employee survey (engagement index)

The weight of the sustainability/corporate social responsibility index is designed to remain stable over time, however the individual sub-components used to form the sustainability/corporate social responsibility index may evolve in the future to address sustainability priorities facing the Company and society.

Long-term incentive

The purpose of the long-term incentive, through the grant of stock awards, is to motivate the Senior Management to deliver sustainable long-term shareholder value through long-term profitability and share price growth.

In accordance with the current long-term incentive plan, the vesting of unvested stock awards in respect of:

(i)     the Executive Committee, is subject to the achievement of performance conditions and calculated over a three-year performance period. Grants of unvested stock awards made in 2023 and 2024 will fully vest, subject to performance conditions, in 2026 and 2027 respectively, provided also that the eligible employee is still an employee of the Company at such time; and

(ii)     the Executive Vice Presidents, is subject to the achievement of performance conditions and will vest over a three-year horizon from the date of the grant, with 32% vesting after one year, a further 32% after two years and the remaining 36% after three years, provided also that the eligible employee is still an employee of the Company at such time.

The Supervisory Board determines whether the performance criteria are met and concludes whether and to which extent all eligible employees are entitled to any stock awards under the long-term incentive plan.

From 2021, a new sustainability/corporate social responsibility index has been introduced among the performance conditions for the long-term incentive.

105

For the 2023 long-term incentive, the sustainability/corporate social responsibility index was comprised of the following KPIs:

•Environment/climate: measured against, amongst others, the direct emissions (kCO2 equivalent)

•Diversity & inclusion: measured against, amongst others, gender ratio among management levels

•ESG investor index: measured against, amongst others, the Dow Jones sustainability indices

•Carbon rating agency: measured against, amongst others, the CDP carbon rating

The weight of the sustainability/corporate social responsibility index is designed to remain stable for future grants, however the individual sub-components used to form the sustainability/corporate social responsibility index may evolve in the future to address sustainability priorities facing the Company and society.

Pension plan, life and medical insurance

Our Supervisory Board has approved the establishment of a complementary pension plan for certain key executives as selected by the sole member of the Managing Board, our President and Chief Executive Officer, according to the general criteria of eligibility and service as determined by the Supervisory Board upon the proposal of its Compensation Committee. With respect to such complementary pension plan, we have set up an independent foundation under Swiss law which manages the plan and to which we make contributions. Pursuant to this plan, in 2023, we made a contribution of approximately $0.5 million to the plan of the sole member of the Managing Board, our President and Chief Executive Officer, and of $1.05 million to the plan for all beneficiaries other than the sole member of the Managing Board, our President and Chief Executive Officer. The amount of pension plan payments made for other beneficiaries, such as former employees retired in 2023 and/or no longer salaried in 2023, was $1.1 million.

The members of our Senior Management, including the sole member of the Managing Board, our President and Chief Executive Officer, were covered in 2023 under certain group life and medical insurance programs provided by us. The aggregate additional amount set aside by us in 2023 to provide pension, retirement or similar benefits to our Senior Management, including the sole member of the Managing Board, our President and Chief Executive Officer, including the amounts allocated to the complementary pension plan described above, is estimated to have been approximately $8.3 million, which includes statutory employer contributions for state run retirement, similar benefit programs and other miscellaneous allowances.

The structure of our remuneration for our (i) Managing Board, President and Chief Executive Officer, (ii) Senior Management, and (iii) certain other groups of senior employees is aligned and consists of a base salary, short-term incentive and long-term incentive, under specified conditions. The standard benefits for the aforementioned groups are also aligned.

Share Ownership and Stock Awards

i.Share Ownership

None of the members of our Supervisory Board, Managing Board or Senior Management holds shares or options to acquire shares representing more than 1% of our issued share capital.

ii.Overview of Stock Awards and Options

Our stock-based compensation plans are designed to incentivize, attract and retain our executives and key employees by aligning compensation with our performance and the evolution of our share price. Since 2005, we have adopted long-term incentive plans based on stock awards for our management as well as key employees. Furthermore, until 2012, the Compensation Committee (on behalf of the Supervisory Board and with its approval) granted stock-based awards (the options to acquire common shares in the share capital of the Company) to the members and professionals of the Supervisory Board. For a description of our stock option plans and unvested share award plans, please see Note 18 to our Consolidated Financial Statements, which is incorporated herein by reference.

112

Pursuant to the shareholders’ resolutions adopted by our General Meetings of Shareholders, our Supervisory Board, upon the proposal of the Managing Board and the recommendation of the Compensation Committee, took the following actions:

•approved conditions relating to our 2021 unvested stock award allocation under the 2021 Unvested Stock Award Plan, including restriction criteria linked to our performance (for selected employees);

•approved conditions relating to our 2022 unvested stock award allocation under the 2021 Unvested Stock Award Plan, including restriction criteria linked to our performance (for selected employees); and

•approved conditions relating to our 2023 unvested stock award allocation under the 2021 Unvested Stock Award Plan, including restriction criteria linked to our performance (for selected employees).

The sale or purchase of shares of our stock by the members or professionals of our Supervisory Board, the sole member of the Managing Board, our President and Chief Executive Officer, and all our employees are subject to an internal policy which involves, inter alia, certain blackout periods.

Item 7.    Major Shareholders and Related Party Transactions

Major Shareholders

The following table sets forth certain information with respect to the ownership of our issued common shares as of December 31, 2023 based on information available to us:

	Common Shares Owned
Shareholders	Number	%
STMicroelectronics Holding N.V. (“ST Holding”)	250,704,754	27.5
Public(1)	652,066,327	71.6
Treasury shares	8,510,839	0.9
Total	911,281,920	100.0

_______________

(1)    According to the report available on Schedule 13G filed with the SEC on February 12, 2024, we understand that as of December 31, 2023 BlackRock, Inc. is the beneficial owner of 76,018,157 of our common shares (representing approximately 8.3% of our issued common shares).

We are not aware of any significant change over the past three years in the percentage ownership of our shares by ST Holding, our major shareholder. ST Holding does not have any different voting rights from those of our other shareholders.

Shareholders Agreement

According to the report on Schedule 13G (“2024 ST Holding 13G”) jointly filed with the SEC on February 14, 2024, by ST Holding, Bpifrance Participations S.A., a successor to its former wholly-owned subsidiary FT1CI, (“Bpifrance”), the Italian Ministry of the Economy and Finance (the “MEF” and together with Bpifrance hereinafter the “STH Shareholders”), Caisse des d'epots et consignations (“CDC”), EPIC BpiFrance (“EPIC”) and Bpifrance S.A., the Italian Government and the French Government, each indirectly through the MEF and Bpifrance, respectively, held 13.9% of our share capital as of December 31, 2023. The ownership percentages of each the MEF and Bpifrance are based on 902,771,081 shares outstanding as of December 31, 2023. Bpifrance is 99.9% owned by Bpifrance S.A., in which CDC and EPIC each hold a 49.2% participation. Below is a brief summary of certain details from the 2024 ST Holding 13G.

Corporate Governance

Managing Board and Supervisory Board members can only be appointed by the general meeting of shareholders upon a proposal by the Supervisory Board. The Supervisory Board passes resolutions, including on such a proposal, by at least three quarters of the votes of the members in office. The STH Shareholders Agreement, to which we are not a party, furthermore provides that: (i) each of the STH Shareholders, Bpifrance, on the one hand, and the MEF, on the other hand, may propose the same number of members for election to the Supervisory Board by our shareholders, and ST Holding shall vote in favor of such members; and (ii) any decision relating to the voting rights of ST Holding shall require the unanimous approval of the STH Shareholders. ST Holding may therefore be in a position to effectively control actions that require shareholder approval, including, as discussed above, the proposal of six out of nine members for election to our Supervisory Board (three members by each STH Shareholder) and the appointment of our Managing Board, as well as corporate actions, and the issuance of new shares or other securities. As a result of the STH Shareholders Agreement, the Chairman of our Supervisory Board is proposed by an STH Shareholder for a three-year term, and the Vice-Chairman of our Supervisory Board is proposed by the other STH Shareholder for the same period, and vice-versa for the following three-year term. The STH Shareholder proposing the appointment of the Chairman may furthermore propose the appointment of the Assistant Secretary of our Supervisory Board, and the STH Shareholder proposing the appointment of Vice-Chairman proposes the appointment of the Secretary of our Supervisory Board. Finally, each STH Shareholder also proposes the appointment of a financial controller to the Supervisory Board.

114

Ownership of ST Shares

The STH Shareholders Agreement provides that each STH Shareholder retains the right to cause ST Holding to dispose of its stake in us at its sole discretion pursuant to the issuance of financial instruments, an equity swap, a structured finance deal or a straight sale; however, except in the case of a public offer, no sales by any party to the STH Shareholders Agreement may be made of any of our shares or any shares of Bpifrance or ST Holding to any of our top ten competitors or any company controlling such a competitor. The STH Shareholders Agreement also requires all of the parties to the STH Shareholders Agreement to hold their stakes in us at all time through the current holding structure of ST Holding, subject to certain limited exceptions, and precludes all such parties and their affiliates from acquiring any of our common shares other than through ST Holding.

Change of Control Provision

The STH Shareholders Agreement provides for tag-along rights, pre-emptive rights, and provisions with respect to a change of control of any of the STH Shareholders or any controlling shareholder of Bpifrance, on the one hand, and the Italian Ministry of the Economy and Finance, on the other hand. The STH Shareholders may transfer shares of ST Holding and/or Bpifrance, as applicable, to any of their respective affiliates, which could include entities ultimately controlled by the Italian Government or the French Government.

Preference Shares

We have an option agreement with an independent foundation, Stichting Continuïteit ST (the “Stichting”), whereby the Stichting can acquire a maximum of 540,000,000 preference shares in the event of actions which the board of the Stichting determines would be contrary to our interests, our shareholders and our other stakeholders and which in the event of a creeping acquisition or an unsolicited offer for our common shares are not supported by our Managing Board and Supervisory Board. If the Stichting exercises its call option and acquires preference shares, it must pay at least 25% of the par value of such preference shares. The preference shares may remain outstanding for no longer than two years.

No preference shares have been issued to date. The effect of the preference shares may be to deter potential acquirers from effecting an unsolicited acquisition resulting in a change of control as well as to create a level-playing field in the event actions which are considered hostile by our Managing Board and Supervisory Board, as described above, occur and which the board of the Stichting determines to be contrary to our interests and our shareholders and other stakeholders. In addition, any issuance of additional capital within the limits of our authorized share capital, as approved by our shareholders, is subject to approval by our Supervisory Board, other than pursuant to an exercise of the call option granted to the Stichting.

Related Party Transactions

Legal Proceedings

For a description of our material pending legal proceedings, please see Note 25 “Commitments, Contingencies, Claims and Legal Proceedings” to our Consolidated Financial Statements, which is incorporated herein by reference.

Dividend Policy

Our dividend policy reads as follows: “STMicroelectronics seeks to use its available cash in order to develop and enhance its position in a competitive semiconductor market while at the same time managing its

115

cash resources to reward its shareholders for their investment and trust in STMicroelectronics. Based on its results, projected capital requirements as well as business conditions and prospects, the Managing Board proposes on an annual basis to the Supervisory Board, whenever deemed possible and desirable in line with STMicroelectronics’ objectives and financial situation, the distribution of a quarterly cash dividend, if any. The Supervisory Board, upon the proposal of the Managing Board, decides or proposes on an annual basis, in accordance with this policy, which portion of the profits or distributable reserves shall not be retained in reserves to fund future growth or for other purposes and makes a proposal concerning the amount, if any, of the quarterly cash dividend”.

On May 24, 2023, our shareholders approved a cash dividend of US$0.24 per outstanding share of our common stock, which was distributed in quarterly installments of US$0.06 in each of the second, third and fourth quarters of 2023 and will also be distributed in the first quarter of 2024. Future dividends, if any, and their timing and amounts may be affected by our accumulated profits, our capacity to generate cash flow, our financial situation, the general economic situation and prospects and any other factors that the Supervisory Board, upon the recommendation of our Managing Board, shall deem important. For a history of dividends paid by us to our shareholders in the past three years, see Note 18 to our Consolidated Financial Statements “Shareholders’ Equity – Dividends”.

Item 10.    Additional Information

A.    Share Capital

Not applicable.

B.    Memorandum and Articles of Association

We were incorporated under the laws of The Netherlands by deed of May 21, 1987 and are registered with the trade register (handelsregister) of the Dutch Chamber of Commerce (Kamer van Koophandel) under no. 33194537. Set forth below is a summary of certain provisions of our Articles of Association and relevant Dutch law. The summary below does not purport to be complete and is qualified in its entirety by reference to our Articles of Association, most recently amended on June 20, 2017, and relevant Dutch law.

Object and Purposes (Article 2)

The objects of our company is to participate in or take, in any manner, any interests in other business enterprises; to manage such enterprises; to carry on business in semiconductors and electronic devices; to take and grant licenses and other industrial property interests; to assume commitments in the name of any enterprises with which we may be associated within a group of companies; to take financial interests in such enterprises and to take any other action, such as but not limited to the granting of securities or the undertaking of obligations on

116

behalf of third parties, which in the broadest sense of the term, may be related or contribute to the aforementioned objects.

Supervisory Board Members

Our Articles of Association do not include any provisions related to a Supervisory Board member’s:

•power to vote on proposals, arrangements or contracts in which such member is materially interested;

•power, in the absence of an independent quorum, to vote on compensation to themselves or any members of the Supervisory Board;

•borrowing powers exercisable by the directors and how such borrowing powers can be varied;

•mandatory retirement age; or

•number of owned shares in our company required to qualify as a Supervisory Board member.

Our Supervisory Board charter and Dutch law, however, explicitly prohibit members of our Supervisory Board from participating in discussions and voting on matters where they have a conflict of interest. If our entire Supervisory Board has a conflict of interest, our shareholders’ meeting is the competent corporate body to adopt the relevant resolution. Our Articles of Association provide that our shareholders’ meeting must adopt the compensation of our Supervisory Board members. Neither our Articles of Association nor our Supervisory Board charter has a requirement or policy that Supervisory Board members hold a minimum number of our common shares.

We have balanced participation by men and women on our Supervisory Board and currently, our Supervisory Board comprises nine members of which 4 are female and 5 are male.

Distribution of Profits (Articles 37, 38, 39 and 40)

Subject to certain exceptions, dividends may only be paid out of the profits as shown in our adopted annual accounts. Our profits must first be used to set up and maintain reserves required by Dutch law and our Articles of Association. Subsequently, if any of our preference shares are issued and outstanding, preference shareholders shall be paid a dividend, which will be a percentage of the paid up part of the par value of their preference shares. Our Supervisory Board may then, upon proposal of our Managing Board, also establish reserves out of our annual profits. The portion of our annual profits that remains after the establishment or maintenance of reserves and the payment of a dividend to our preference shareholders is at the disposal of our shareholders’ meeting. No distribution may be made to our shareholders when the equity after such distribution is or becomes inferior to the fully-paid share capital, increased by the legal reserves. Our preference shares are cumulative by nature, which means that if in a financial year the dividend or the preference shares cannot be (fully) paid, the deficit must first be paid in the following financial year(s).

Our Supervisory Board independently as well as our shareholders’ meeting, upon the proposal of our Supervisory Board, may each declare distributions out of our share premium reserve and other reserves available for shareholder distributions under Dutch law. Pursuant to a resolution of our Supervisory Board, distributions adopted by the shareholders’ meeting may be fully or partially made in the form of our new shares to be issued. Our Supervisory Board may, subject to certain statutory provisions, make one or more interim distributions in respect of any year before the accounts for such year have been adopted at a shareholders’ meeting. Rights to cash dividends and distributions that have not been collected within five years after the date on which they became due and payable shall revert to us.

For the history of dividends paid by us to our shareholders in the past five years, see Note 18 to our Consolidated Financial Statements.

Notice Convening the Shareholders’ Meeting (Articles 25, 26, 27, 28 and 29)

Our ordinary shareholders’ meetings are held at least annually, within six months after the close of each financial year, in The Netherlands. Extraordinary shareholders’ meetings may be held as often as our

117

Supervisory Board deems necessary, and must be held upon the written request of registered shareholders or other persons entitled to attend shareholders’ meetings of at least 10% of the total issued share capital to our Managing Board or our Supervisory Board specifying in detail the business to be dealt with. Such written requests may not be submitted electronically.

The notice convening the shareholders’ meeting shall be given in such manner as shall be authorized or required by law with due observance of the statutory notice period, which is currently 42 days prior to the meeting.

One or more shareholders or other persons entitled to attend shareholders’ meetings representing at least one-tenth of our issued share capital may, provided that the request was made at least five days prior to the date of convocation of the meeting, request proposals to be included on the agenda. Furthermore, a request that a proposal be included on the agenda can be made in writing to our Managing Board within sixty days of a meeting by persons who are entitled to attend our shareholders’ meetings who, solely or jointly, represent at least 1% of our issued share capital or a market value of at least €50 million. The aforementioned requests may not be submitted electronically and must comply with conditions stipulated by our Managing Board, subject to the approval of our Supervisory Board, which shall be posted on our website. Pursuant to Dutch law a shareholder requesting discussion of an agenda item must disclose to us its entire beneficial interest (long and short position) and we are required to disclose this information on our website.

We are exempt from the proxy solicitation rules under the United States Securities Exchange Act of 1934. Euroclear France will provide notice of shareholders’ meetings to, and compile voting instructions from, holders of shares held directly or indirectly through Euroclear France. The Depository Trust Company (“DTC”) will provide notice of shareholders’ meetings to holders of shares held directly or indirectly through DTC and the New York Transfer Agent and Registrar will compile voting instructions. In order for holders of shares held directly or indirectly through Euroclear France to attend shareholders’ meetings in person, such holders must withdraw their shares from Euroclear France and have such shares registered directly in their name or in the name of their nominee. In order for holders of shares held directly or indirectly through DTC to attend shareholders’ meetings of shareholders in person, such holders need not withdraw such shares from DTC but must follow rules and procedures established by the New York Transfer Agent and Registrar.

Attendance at Shareholders’ Meetings and Voting Rights (Articles 30, 31, 32, 33 and 34)

Each share is entitled to one vote.

All shareholders and other persons entitled to attend shareholders’ meetings may attend in person or be represented by a person holding a written proxy. Shareholders and other persons entitled to vote, may do so pursuant to our Articles of Association. Subject to the approval of our Supervisory Board, our Managing Board may resolve to facilitate the use of electronic means of communication in relation to the participation and voting in shareholders’ meetings. Dutch law prescribes a fixed registration date of 28 days prior to the shareholders’ meeting, which means that shareholders and other persons entitled to attend shareholders’ meetings are those persons who have such rights at the 28th day prior to the shareholders’ meeting and, as such, are registered in a register designated by our Managing Board, regardless of who is a shareholder or otherwise a person entitled to attend shareholders’ meetings at the time of the meeting if a registration date would not be applicable. In the notice convening the shareholders’ meeting, the time of registration must be mentioned as well as the manner in which shareholders and other persons entitled to attend shareholders’ meetings can register themselves and the manner in which they can exercise their rights.

All matters regarding admittance to the shareholders’ meeting, the exercise of voting rights and the result of voting, as well as any other matters regarding the business of the shareholders’ meeting, shall be decided upon by the chairman of that meeting, in accordance with the requirements of Section 2:13 of the Dutch Civil Code.

Our Articles of Association allow for separate meetings for holders of common shares and for holders of preference shares. At a meeting of holders of preference shares at which the entire issued capital of shares of such class is represented, valid resolutions may be adopted even if the requirements in respect of the place of the meeting and the giving of notice have not been observed, provided that such resolutions are adopted by unanimous vote. Also, valid resolutions of preference shareholder meetings may be adopted outside a meeting if

118

all persons entitled to vote on our preference shares indicate in writing that they vote in favor of the proposed resolution, provided that no depositary receipts for preference shares have been issued with our cooperation.

Authority of our Shareholders’ Meeting (Articles 12, 16, 19, 25, 28, 32 and 41)

Our AGM may decide upon (i) the discharge of the members of our Managing Board for their management during the past financial year and the discharge of the members of our Supervisory Board for their supervision during the past financial year; (ii) the adoption of our statutory annual accounts and the distribution of dividends; (iii) the appointment of the members of our Supervisory Board and our Managing Board; and (iv) any other resolutions listed on the agenda.

Furthermore, our shareholders’ meeting has to approve resolutions of our Managing Board regarding a significant change in the identity or nature of us or our enterprise, including in any event (i) transferring our enterprise or practically our entire enterprise to a third-party, (ii) entering into or canceling any long-term cooperation between us or a subsidiary of us and any other legal person or company or as a fully liable general partner of a limited partnership or a general partnership, provided that such cooperation or the cancellation thereof is of essential importance to us, and (iii) us or a subsidiary of us acquiring or disposing of a participating interest in the capital of a company with a value of at least one-third of our total assets according to our consolidated balance sheets and notes thereto in our most recently adopted annual accounts.

Our Articles of Association may only be amended (and our liquidation can only be decided on) if amendments are proposed by our Supervisory Board and approved by a simple majority of the votes cast at a shareholders’ meeting at which at least 15% of the issued and outstanding share capital is present or represented. The complete proposal for the amendment (or liquidation) must be made available for inspection by the shareholders and the other persons entitled to attend shareholders’ meetings at our offices as from the day of the notice convening such meeting until the end of the meeting. Any amendment of our Articles of Association that negatively affects the rights of the holders of a certain class of shares requires the prior approval of the meeting of holders of such class of shares.

Quorum and Majority (Articles 4, 13 and 32)

Unless otherwise required by our Articles of Association or Dutch law, resolutions of shareholders’ meetings require the approval of a majority of the votes cast at a meeting at which at least 15% of the issued and outstanding share capital is present or represented, subject to the provisions explained below. We may not vote our common shares held in treasury. Blank and invalid votes shall not be counted.

A quorum of shareholders, present or represented, holding at least half of our issued share capital, is required to dismiss a member of our Managing Board, unless the dismissal is proposed by our Supervisory Board. In the event of the lack of a quorum, a second shareholders’ meeting must be held within four weeks, with no applicable quorum requirement. Any decision or authorization by the shareholders’ meeting which has or could have the effect of excluding or limiting preferential subscription rights must be taken by a majority of at least two-thirds of the votes cast, if at the shareholders’ meeting less than 50% of the issued and outstanding share capital is present or represented. Otherwise such a resolution can be taken by a simple majority at a meeting at which at least 15% of the issued and outstanding share capital is represented.

Disclosure of holdings and capital interest under Dutch Law

Holders of our shares (including certain comparable instruments, such as instruments with a value (partly) dependent on shares or distributions on shares, or contracts creating an economic position similar to shares) or voting rights (including potential interests, such as via options or convertible bonds) may have disclosure obligations under Dutch law. Any person or entity whose direct or indirect interest in our share capital or voting rights (including potential interest) reaches, exceeds or falls below a certain threshold must make a disclosure to the AFM immediately. The threshold percentages are 3%, 5%, 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 75% and 95%. If a person’s direct or indirect interest in the share capital or voting rights passively reaches, exceeds or falls below the abovementioned thresholds (e.g. as a result of a change in the capital of the company), the person in question must give notice to the AFM no later than the fourth trading day after the AFM has published the change in the share capital and/or voting rights in the public register. In addition, a

119

notification requirement applies in respect of shares with special statutory rights (e.g. priority shares), regardless of the abovementioned percentages.

Furthermore, each person who is or ought to be aware that the substantial holding he holds in the Company, reaches, exceeds or falls below any of the abovementioned thresholds vis-à-vis his most recent notification to the AFM, which change relates to the composition of the notification as a result of certain acts (e.g. (i) the exchange of certain financial instruments for shares or depositary receipts for shares, (ii) the exchange of shares for depositary receipts for shares, or (iii) as a result of the exercise of rights pursuant to a contract for the acquisition of voting rights) must give notice to the AFM no later than the fourth trading day after he became or ought to be aware of this change.

For the purpose of calculating the percentage of capital interest or voting rights, among others, the following interests must be taken into account: (i) those directly held by him; (ii) those held by his controlled undertakings for purposes of the Dutch Financial Supervision Act; (iii) shares held by a third-party for such person’s account and the votes such third-party may exercise; (iv) the votes held by a third-party if such person has concluded an oral or written voting agreement with such party which provides for a lasting common policy on voting; (v) the votes held by a third-party if such person has concluded an oral or written agreement with such party which provides for a temporary and paid transfer of the votes; and (vi) the votes which a person may exercise as a proxy but in his own discretion. A person who has a 3% or larger interest in the share capital or voting rights and who ceases to be a controlled undertaking must without delay notify the AFM. As of that moment, all notification obligations under the Dutch Financial Supervision Act will become applicable to the former controlled undertaking itself. The management company of a common fund (beleggingsfonds) shall be deemed to have the disposal of the shares held by the depositary and the related voting rights. The depositary of a common fund shall be deemed not to have the disposal of shares or voting rights. Furthermore, special rules apply to the attribution of the ordinary shares which are part of the property of a partnership or other community of property. A holder of a pledge or right of usufruct in respect of our shares can also be subject to a notification obligation if such person has, or can acquire, the right to vote on our shares. If a pledgor or usufructuary acquires such voting rights, this may also trigger a notification obligation for the holder of our shares. A person is also deemed to hold shares if he has a financial instrument (i) whose rise in value depends in part on the rise in value of the underlying shares or on dividend or other payments on those shares (in other words, a long position must be held in those shares), and (ii) which does not entitle him to acquire shares in a listed company (i.e., it is a cash-settled financial instrument). In addition, a person who may, by virtue of an option, be obliged to buy shares in a listed company is also equated with a shareholder. Moreover, a person who has entered into a contract (other than a cash-settled financial instrument) that gives him an economic position comparable to that of a shareholder in a listed company is also deemed to hold shares for the purposes of the disclosure obligation.

The holder of a financial instrument representing a short position in our shares is required to notify the AFM if such short position, expressed in a capital percentage, reaches or crosses a threshold percentage. The threshold percentages are the same as referred to above in this section. Short position refers to the gross short position (i.e., a long position held by the holder cannot be offset against the short position). There is also a requirement to notify the AFM of the net short position (i.e., long positions are offset against short positions) if such short position, expressed in a capital percentage, reaches or crosses a threshold percentage; The threshold percentages are 0.2% and each 0.1% above that. Notifications as of 0.5% and each 0.1% above that will be published by the AFM. The notification shall be made no later than 3:30 pm CET on the following trading day.

Under Dutch law, the sole member of our Managing Board and each of the members of our Supervisory Board must without delay notify the AFM of any changes in his interest or potential interest in our share capital or voting rights. Under the European Market Abuse Regulation, the sole member of our Managing Board, the members of the Executive Committee and each of the members of our Supervisory Board, as well as any other person who would have the power to take managerial decisions affecting the future developments and business prospects of the Company having regular access to inside information relating, directly or indirectly, to the Company, must notify the AFM of any transactions conducted for his or her own account relating to the shares or in financial instruments the value of which is also based on the value of the shares. In addition, certain persons who are closely associated with members of the Managing Board, the Executive Committee and Supervisory Board or any of the other persons as described above, are required to notify the AFM of any transactions conducted for their own account relating to the shares or in financial instruments the value of which is also based on the value of the shares.

120

The AFM publishes all notifications on its public website (www.afm.nl). Non-compliance with the notification obligations under European or Dutch law can lead to imprisonment or criminal fines, or administrative fines or other administrative sanctions. In addition, non-compliance with these notification obligations may lead to civil sanctions, including, without limitation, suspension of the voting rights attaching to our shares held by the offender for a maximum of three years, (suspension and) nullification of a resolution adopted by our shareholders’ meeting (if it is likely that such resolution would not have been adopted if the offender had not voted) and a prohibition for the offender to acquire our shares or votes for a period of no more than five years. Shareholders are advised to consult with their own legal advisers to determine whether notification obligations apply to them.

Share Capital (Articles 4, 5 and 6)

Our shares may not be issued at less than their par value. Our common shares must be fully paid up at the time of their issuance. Our preference shares must be paid up for at least 25% of their par value at the time of their issuance (and the remaining 75% if and when requested by our Managing Board). Our authorized share capital is not restricted by redemption provisions, sinking fund provisions or liability to further capital calls by us. Our Articles of Association allows for the acquisition of own shares and the cancellation of shares.

Type II shares are common shares in the form of an entry in our shareholders register with the issue of a share certificate consisting of a main part without a dividend coupon. In addition to type II shares, type I shares are available. Type I shares are common shares in the form of an entry in our shareholders register without the issue of a share certificate. Type II shares are only available should our Supervisory Board decide to offer them. Our preference shares are in the form of an entry in our shareholders register without issue of a share certificate.

Non-issued authorized share capital, which is different from issued share capital, allows us to proceed with capital increases excluding the preemptive rights, upon our Supervisory Board’s decision. Other securities in circulation which give access to our share capital include (i) the options giving the right to subscribe to our shares granted to our employees, including the sole member of our Managing Board and our senior managers; (ii) the options giving the right to subscribe to our shares granted in the past to the members of our Supervisory Board, its secretaries and controllers, as described in “Item 6. Directors, Senior Management and Employees”; (iii) our bonds; and (iv) the option giving the right to subscribe to our preference shares to Stichting Continuïteit ST. See “Item 7. Major Shareholders and Related Party Transactions”. We do not have securities not representing our share capital.

Our shareholders’ meeting, upon proposal and on the terms and conditions set by our Supervisory Board, has the power to issue shares and rights to subscribe for shares. The shareholders’ meeting may authorize our Supervisory Board, for a period of no more than five years, to issue shares and rights to subscribe for shares and to determine the terms and conditions of such issuances.

Each holder of common shares has a pro rata preemptive right to subscribe to an offering of common shares issued for cash in proportion to the number of common shares which he owns. There is no preemptive right with respect to an offering of shares for non-cash consideration, with respect to an offering of shares to our employees or to the employees of one of our subsidiaries, or with respect to preference shares.

Our shareholders’ meeting, upon proposal by our Supervisory Board, has the power to limit or exclude preemptive rights in connection with new issuances of shares. Such a resolution of the shareholders’ meeting must be taken with a majority of at least two-thirds of the votes cast if at such shareholders’ meeting less than 50% of the issued and outstanding share capital is present or represented. Otherwise such a resolution can be taken by a simple majority of the votes cast at a shareholders’ meeting at which at least 15% of our issued and outstanding share capital is present or represented. Our shareholders’ meeting may authorize our Supervisory Board, for a period of no more than five years, to limit or exclude preemptive rights.

Acquisition of Shares in Our Own Share Capital (Article 5)

We may acquire our own shares, subject to certain provisions of Dutch law and of our Articles of Association. Share acquisitions may be effected by our Managing Board, subject to the approval of our Supervisory Board, only if the shareholders’ meeting has authorized our Managing Board to effect such repurchases, which authorization may apply for a maximum period of 18 months. We may not vote shares we

121

hold in treasury. Our purchases of our own shares are subject to acquisition price conditions as authorized by our shareholders’ meeting. Our Articles of Association provide that we shall be able to acquire shares in our own share capital in order to transfer these shares under employee stock option or stock purchase plans, without an authorization of our shareholders’ meeting.

Upon the proposal of our Supervisory Board, our shareholders’ meeting may, in accordance with the legal provisions, reduce our issued capital by canceling the shares that we hold in treasury, by reducing the par value of the shares or by canceling our preference shares.

Liquidation Rights (Articles 42 and 43)

In the event of our dissolution and liquidation, after payment of all debts and liquidation expenses, the holders of preference shares if issued, would receive the paid up portion of the par value of their preference shares. Any assets then remaining shall be distributed among the registered holders of common shares in proportion to the par value of their shareholdings.

Limitations on Right to Hold or Vote Shares

There are currently no limitations imposed by Dutch law or by our Articles of Association on the right of non-resident holders to hold or vote the shares.

C.    Material Contracts

None.

D.    Exchange Controls

None.

E.    Taxation

Dutch Taxation

This section only outlines certain material Dutch tax consequences of the acquisition, holding and disposal of our common shares. This section does not purport to describe all possible tax considerations or consequences that may be relevant to a holder or prospective holder of common shares and does not purport to deal with the tax consequences applicable to all categories of investors, some of which (such as trusts or similar arrangements) may be subject to special rules. In view of its general nature, this section should be treated with corresponding caution.

Tax matters are complex, and the tax consequences of the acquisition, holding and disposal to a particular holder of common shares will depend in part on such holder’s circumstances. Accordingly, you are urged to consult your own tax advisor for a full understanding of the tax consequences of the acquisition, holding and disposal to you, including the applicability and effect of Dutch tax laws.

Where in this section English terms and expressions are used to refer to Dutch concepts, the meaning to be attributed to such terms and expressions shall be the meaning to be attributed to the equivalent Dutch concepts under Dutch tax law. Where in this section the terms “The Netherlands” and “Dutch” are used, these refer solely to the European part of the Kingdom of The Netherlands.

This section assumes that we are organized, and that our business will be conducted, in the manner outlined in this Form 20-F. A change to such organizational structure or to the manner in which we conduct our business may invalidate the contents of this section, which will not be updated to reflect any such change.

Please note that this section does not describe the Dutch tax consequences for a holder of our common shares:

(i)who may be deemed an owner of our common shares for Dutch tax purposes pursuant to specific
statutory attribution rules in Dutch tax law;

122

(ii)who has a substantial interest (aanmerkelijk belang) or deemed substantial interest (fictief aanmerkelijk belang) in us under the Dutch Income Tax Act 2001 (Wet inkomstenbelasting 2001). Generally, a holder is considered to hold a substantial interest in us if such holder alone or, in the case of an individual, together with such holder’s partner for Dutch income tax purposes, or any relatives by blood or marriage in the direct line (including foster-children), directly or indirectly, holds (i) an interest of 5% or more of the total issued and outstanding capital of us or of 5% or more of the issued and outstanding capital of a certain class of shares; or (ii) rights to acquire, directly or indirectly, such interest; or (iii) certain profit sharing rights that relate to 5% or more of our annual profits or to 5% or more of our liquidation proceeds. A deemed substantial interest may arise if a substantial interest (or part thereof) in has been disposed of, or is deemed to have been disposed of, on a non-recognition basis;

(iii)if the common shares held by such holder qualify or qualified as a participation (deelneming) for purposes of the Dutch Corporate Income Tax Act 1969 (Wet op de vennootschapsbelasting 1969). Generally, a holder's shareholding of, or right to acquire, 5% or more in our nominal paid-up share capital qualifies as a participation. A holder may also have a participation if (a) such holder does not have a shareholding of 5% or more but a related entity (statutorily defined term) has a participation or (b) we are a related entity (statutorily defined term);

(iv)which is or who is entitled to the dividend withholding tax exemption (inhoudingsvrijstelling) with respect to any profits derived from the common shares (as defined in Article 4 of the Dutch Dividend Withholding Tax Act 1965 (Wet op de dividendbelasting). Generally, a holder of common shares may be entitled or required to apply, subject to certain other requirements, the dividend withholding tax exemption if it is an entity and holds an interest of 5% or more in our nominal paid-up share capital;

(v)pension funds, investment institutions (fiscale beleggingsinstellingen) and tax exempt investment institutions (vrijgestelde beleggingsinstellingen) (each as defined in the Dutch Corporate Income Tax Act 1969) and other entities that are, in whole or in part, not subject to or exempt from Dutch corporate income tax, entities that have a function comparable to an investment institution or a tax exempt investment institution, as well as entities that are exempt from corporate income tax in their country of residence, such country of residence being another state of the European Union, Norway, Liechtenstein, Iceland or any other state with which The Netherlands has agreed to exchange information in line with international standards; and

(vi)if such holder is an individual for whom the common shares or any benefit derived from the common shares is a remuneration or deemed to be a remuneration for (employment) activities performed by such holder or certain individuals related to such holder (as defined in the Dutch Income Tax Act 2001).

Dividend withholding tax

Dividends distributed by us are generally subject to Dutch dividend withholding tax at a rate of 15%. Generally, we are responsible for the withholding of such dividend withholding tax at source; the Dutch dividend withholding tax is for the account of the holder of common shares.

The expression “dividends distributed” includes, but is not limited to:

•distributions in cash or in kind, deemed and constructive distributions and repayments of paid-in capital not recognized for Dutch dividend withholding tax purposes;

•liquidation proceeds, proceeds from the redemption of common shares or proceeds from the repurchase of common shares (other than as temporary portfolio investment; tijdelijke belegging) by us or one of our subsidiaries or other affiliated entities, in each case to the extent such proceeds exceed the average paid-in capital of those common shares as recognized for Dutch dividend withholding tax purposes;

123

•an amount equal to the nominal value of the common shares issued or an increase of the nominal value of the common shares, to the extent that no related contribution, recognized for Dutch dividend withholding tax purposes, has been made or will be made; and

•partial repayment of the paid-in capital, recognized for Dutch dividend withholding tax purposes, if and to the extent that we have “net profits” (zuivere winst), unless (i) our general meeting of shareholders has resolved in advance to make such repayment and (ii) the nominal value of the common shares concerned has been reduced by an equal amount by way of an amendment to our articles of association. The term “net profits” includes anticipated profits that have yet to be realized.

Corporate legal entities that are resident or deemed to be resident of The Netherlands for Dutch corporate income tax purposes (“Dutch Resident Entities”) generally are entitled to an exemption from, or a credit for, any Dutch dividend withholding tax against their Dutch corporate income tax liability. The credit in any given year is, however, limited to the amount of Dutch corporate income tax payable in respect of the relevant year with an indefinite carry forward of any excess amount. Individuals who are resident or deemed to be resident of The Netherlands for Dutch personal income tax purposes (“Dutch Resident Individuals”) generally are entitled to a credit for any Dutch dividend withholding tax against their Dutch personal income tax liability and to a refund of any residual Dutch dividend withholding tax. The above generally also applies to holders of common shares that are neither resident nor deemed to be resident of The Netherlands (“Non-Resident Holders”) if the common shares are attributable to a Dutch permanent establishment of such Non-Resident Holder.

A holder of common shares resident of a country other than The Netherlands may, depending on such holder's specific circumstances, be entitled to exemptions from, reduction of, or full or partial refund of, Dutch dividend withholding tax under Dutch domestic tax law, EU law, or treaties for the avoidance of double taxation in effect between The Netherlands and such other country.

Dividend stripping

According to “Dutch domestic anti-dividend stripping” rules, no credit against Dutch tax, exemption from, reduction, or refund of Dutch dividend withholding tax will be granted if the recipient of the dividends we paid is not considered the beneficial owner (uiteindelijk gerechtigde; as described in the Dutch Dividend Withholding Tax Act 1965) of those dividends. This legislation generally targets situations in which a shareholder retains its economic interest in shares but reduces the withholding tax costs on dividends by a transaction with another party. It is not required for these rules to apply that the recipient of the dividends is aware that a dividend stripping transaction took place. The Dutch State Secretary of Finance takes the position that the definition of beneficial ownership introduced by this legislation will also be applied in the context of a double taxation convention. As from 1 January 2024, more stringent rules apply to the setoff, exemption from, and reduction or refund of Dutch dividend withholding tax to address situations where a claim for setoff, exemption, reduction or refund may align with the letter of Dutch tax law or a double taxation convention but goes against the underlying intention or spirit of the dividend stripping rules, as perceived by the legislator. In addition, the burden of proof in cases related to dividend stripping and beneficial owner status has in certain circumstances been shifted from the tax inspector to the person making a claim for a setoff, reduction or refund of or exemption from Dutch dividend withholding tax. Furthermore, for shares traded on a regulated market, including the Ordinary Shares, it has been codified that the record date is used when determining the person who is entitled to the dividend.

Conditional withholding tax on dividends

In addition to the regular Dutch dividend withholding tax as described above, a Dutch conditional withholding tax will be imposed on dividends distributed by us to entities related (gelieerd) to us (within the meaning of the Dutch Withholding Tax Act 2021; Wet bronbelasting 2021), if such related entity:

(i)is considered to be resident (gevestigd) in a jurisdiction that is listed in the yearly updated Dutch Regulation on low-taxing states and non-cooperative jurisdictions for tax purposes (Regeling laagbelastende staten en niet-coöperatieve rechtsgebieden voor belastingdoeleinden) (a “Listed Jurisdiction”); or

124

(ii)has a permanent establishment located in a Listed Jurisdiction to which the common shares are attributable; or

(iii)holds the common shares with the main purpose or one of the main purposes of avoiding taxation for another person or entity and there is an artificial arrangement or transaction or a series of artificial arrangements or transactions; or

(iv)is not considered to be the beneficial owner of the common shares in its jurisdiction of residence because such jurisdiction treats another entity as the beneficial owner of the common shares (a hybrid mismatch); or

(v)is not resident in any jurisdiction (also a hybrid mismatch); or

(vi)is a reverse hybrid (within the meaning of Article 2(12) of the Dutch Corporate Income Tax Act 1969), if and to the extent (x) there is a participant in the reverse hybrid which is related (gelieerd) to the reverse hybrid, (y) the jurisdiction of residence of such participant treats the reverse hybrid as transparent for tax purposes and (z) such participant would have been subject to the Dutch conditional withholding tax in respect of dividends distributed by us without the interposition of the reverse hybrid,

all within the meaning of the Dutch Withholding Tax Act 2021.

The Dutch conditional withholding tax on dividends will be imposed at the highest Dutch corporate income tax rate in effect at the time of the distribution (2024: 25.8%). The Dutch conditional withholding tax on dividends will be reduced, but not below zero, by any regular Dutch dividend withholding tax withheld in respect of the same dividend distribution. As such, based on the currently applicable rates, the overall effective tax rate of withholding the regular Dutch dividend withholding tax (as described above) and the Dutch conditional withholding tax on dividends will not exceed the highest corporate income tax rate in effect at the time of the distribution (2024: 25.8%).

Taxes on income and capital gains

Dutch Resident Entities

Generally, if the holder of common shares is a Dutch Resident Entity, any income derived or deemed to be derived from the common shares or any capital gains realized on the disposal or deemed disposal of the common shares is subject to Dutch corporate income tax at a rate of 19% with respect to taxable profits up to €200,000 and 25.8% with respect to taxable profits in excess of that amount (rates and brackets for 2024).

Dutch Resident Individuals

If the holder of common shares is a Dutch Resident Individual, any income derived or deemed to be derived from the common shares or any capital gains realized on the disposal or deemed disposal of the common shares is subject to Dutch personal income tax at the progressive rates (with a maximum of 49.5% in 2024), if:

(i)the common shares are attributable to an enterprise from which the holder of common shares derives a share of the profit, whether as an entrepreneur (ondernemer) or as a person who has a co-entitlement to the net worth (medegerechtigd tot het vermogen) of such enterprise without being a shareholder (as defined in the Dutch Income Tax Act 2001); or

(ii)the holder of common shares is considered to perform activities with respect to the common shares that go beyond ordinary asset management (normaal, actief vermogensbeheer) or otherwise derives benefits from the common shares that are taxable as benefits from miscellaneous activities (resultaat uit overige werkzaamheden).

Taxation of savings and investments

If the above-mentioned conditions (i) and (ii) do not apply to the Dutch Resident Individual, the common shares will be subject to an annual Dutch income tax under the regime for savings and investments (inkomen uit sparen en beleggen). Taxation only occurs insofar the Dutch Resident Individual's net investment assets for the

125

year exceed a statutory threshold (heffingvrij vermogen). The net investment assets for the year are the fair market value of the investment assets less the fair market value of the liabilities on January 1 of the relevant calendar year (reference date; peildatum). Actual income or capital gains realized in respect of the common shares are as such not subject to Dutch income tax.

The Dutch Resident Individual's assets and liabilities taxed under this regime, including the common shares, are allocated over the following three categories: (a) bank savings (banktegoeden), (b) other investments (overige bezittingen), including the common shares, and (c) liabilities (schulden). The taxable benefit for the year (voordeel uit sparen en beleggen) is equal to the product of (x) the total deemed return divided by the sum of bank savings, other investments and liabilities and (b) the sum of bank savings, other investments and liabilities minus the statutory threshold, and is taxed at a flat rate of 36% (rate for 2024).

The deemed return applicable to other investments, including the common shares, is set at 6.04% for the calendar year 2024. Transactions in the three-month period before and after January 1 of the relevant calendar year implemented to arbitrate between the deemed return percentages applicable to bank savings, other investments and liabilities will for this purpose be ignored if the holder of common shares cannot sufficiently demonstrate that such transactions are implemented for other than tax reasons.

The current Dutch income tax regime for savings and investments was implemented in Dutch tax law following the decision of the Dutch Supreme Court (Hoge Raad) of 24 December 2021 (ECLI:NL:2021:1963) (the “Decision”). In the Decision, the Dutch Supreme Court ruled that the (old) system of taxation for savings and investments based on a deemed return may under specific circumstances contravene with Section 1 of the First Protocol to the European Convention on Human Rights in combination with Section 14 of the European Convention on Human Rights (the “EC-Human Rights”). A new court procedure is pending before the Dutch Supreme Court questioning whether the current tax system for savings and investments is in line with the Decision. On 18 September 2023 (ECLI:NL:PHR:2023:655) the Attorney General Wattel concluded that the new tax system is not in line with the Decision, except for the taxation of bank savings, as the system is, in short, still based on a deemed return rather than actual returns, and as a result, the regime contravenes with the EC-Human Rights. The decision of the Dutch Supreme Court is expected mid-2024. In addition, on 8 September 2023, the former cabinet published a law proposal for a new tax system for savings and investments on the basis of actual returns according to an asset accumulation system, the 'Actual Return Box 3 Act' (Wet werkelijk rendement box 3). The proposed system is expected to come into effect on 1 January 2027 at the earliest. However, it is up to the new cabinet to submit a final law proposal to the Dutch parliament.

Holders of common shares are advised to consult their own tax advisor to ensure that the tax in respect of the common shares is levied in accordance with the applicable Dutch tax rules at the relevant time.

Non-Resident Holders

A holder of common shares that is neither a Dutch Resident Entity nor a Dutch Resident Individual will not be subject to Dutch income tax in respect of income derived or deemed to be derived from the common shares or in respect of capital gains realized on the disposal or deemed disposal of the common shares, provided that:

(i)    such holder does not have an interest in an enterprise or deemed enterprise (as defined in the Dutch Income Tax Act 2001 and the Dutch Corporate Income Tax Act 1969, as applicable) which, in whole or in part, is either effectively managed in The Netherlands or carried on through a permanent establishment, a deemed permanent establishment or a permanent representative in The Netherlands and to which enterprise or part of an enterprise the common shares are attributable; and

(ii)    in the event the holder is an individual, such holder does not carry out any activities in The Netherlands with respect to the common shares that go beyond ordinary asset management and does not otherwise derive benefits from the common shares that are taxable as benefits from miscellaneous activities in The Netherlands.

If you are neither a Dutch Resident Individual nor a Dutch Resident Entity, you will for Dutch tax purposes not carry on or be deemed to carry on an enterprise, in whole or in part, through a permanent

126

establishment or a permanent representative in The Netherlands by reason only of acquisition or holding of the common shares.

Gift and inheritance taxes

Residents of The Netherlands

Gift or inheritance taxes will arise in The Netherlands with respect to a transfer of common shares by way of a gift by, or on the death of, a holder of common shares who is resident or deemed resident of The Netherlands at the time of the gift or such holder's death.

Non-Residents

No gift or inheritance taxes will arise in The Netherlands with respect to a transfer of common shares by way of a gift by, or on the death of, a holder of common shares who is neither resident nor deemed to be resident of The Netherlands, unless:

(i)    in the case of a gift of a common share by an individual who at the date of the gift was neither resident nor deemed to be resident of The Netherlands, such individual dies within 180 days after the date of the gift, while being resident or deemed to be resident of The Netherlands; or

(ii)    in the case of a gift of a common shares is made under a condition precedent, the holder of common shares is resident or is deemed to be resident of The Netherlands at the time the condition is fulfilled; or

(iii)    the transfer is otherwise construed as a gift or inheritance made by, or on behalf of, a person who, at the time of the gift or death, is or is deemed to be resident of The Netherlands.

For purposes of Dutch gift and inheritance taxes, amongst others, a person that holds the Dutch nationality will be deemed to be resident of The Netherlands if such person has been a resident of The Netherlands at any time during the ten years preceding the date of the gift or such person’s death. Additionally, for purposes of Dutch gift tax, amongst others, a person not holding the Dutch nationality will be deemed to be resident of The Netherlands if such person has been a resident of The Netherlands at any time during the twelve months preceding the date of the gift. Applicable tax treaties may override deemed residency.

Value added tax (VAT)

No Dutch VAT will be payable by a holder of common shares in respect of any payment in consideration for the holding or disposal of the common shares.

Stamp Duties

No Dutch documentation taxes (commonly referred to as stamp duties) will be payable by a holder of common shares in respect of any payment in consideration for the holding or disposal of the common shares.

United States Federal Income Taxation

The following discussion is a general summary of the material U.S. federal income tax consequences to a U.S. holder (as defined below) of the ownership and disposition of our common shares. You are a U.S. holder only if you are a beneficial owner of common shares:

•that is, for U.S. federal income tax purposes, (a) a citizen or individual resident of the United States, (b) a U.S. domestic corporation or a U.S. domestic entity taxable as a corporation, (c) an estate, the income of which is subject to U.S. federal income taxation regardless of its source, or (d) a trust, if a court within the United States can exercise primary supervision over the administration of the trust and one or more U.S. persons are authorized to control all substantial decisions of the trust;

127

•that owns, directly, indirectly or by attribution, less than 10% of our voting power or outstanding share capital;

•that holds the common shares as capital assets;

•whose functional currency for U.S. federal income tax purposes is the U.S. dollar;

•that is a resident of the United States and not also a resident of The Netherlands for purposes of the United States – The Netherlands Income Tax Treaty (the “U.S./NL Income Tax Treaty”);

•that is entitled, under the “limitation on benefits” provisions contained in the U.S./NL Income Tax Treaty, to the benefits of the U.S./NL Income Tax Treaty; and

•that does not have a permanent establishment or fixed base in The Netherlands.

This summary does not discuss all of the tax consequences that may be relevant to you in light of your particular circumstances. Also, it does not address holders that may be subject to special rules including, but not limited to, U.S. expatriates, tax-exempt organizations, persons subject to the alternative minimum taxes, banks, securities broker-dealers, financial institutions, regulated investment companies, insurance companies, traders in securities who elect to apply a mark-to-market method of accounting, persons holding our common shares as part of a straddle, hedging or conversion transaction, or persons who acquired common shares pursuant to the exercise of employee stock options or otherwise as compensation. Because this is a general summary, you are advised to consult your own tax advisor with respect to the U.S. federal, state, local and applicable foreign tax consequences of the ownership and disposition of our common shares. In addition, you are advised to consult your own tax advisor concerning whether you are entitled to benefits under the U.S./NL Income Tax Treaty.

If a partnership (including for this purpose any entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds common shares, the tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership. If you are a partner in a partnership that holds common shares, you are urged to consult your own tax advisor regarding the specific tax consequences of the ownership and the disposition of common shares.

This summary is based on the Internal Revenue Code of 1986, as amended, the U.S./NL Income Tax Treaty, judicial decisions, administrative pronouncements and existing, temporary and proposed Treasury regulations as of the date of this Form 20-F, all of which are subject to change or changes in interpretation, possibly with retroactive effect.

Dividends

In general, you must include the gross amount of distributions paid (including the amount of any Dutch taxes withheld from those distributions) to you by us with respect to the common shares in your gross income as foreign-source taxable dividend income. The amount of any distribution paid in foreign currency (including the amount of any Dutch withholding tax thereon) will be equal to the U.S. dollar value of the foreign currency on the date of actual or constructive receipt by you regardless of whether the payment is in fact converted into U.S. dollars at that time. Gain or loss, if any, realized on a subsequent sale or other disposition of such foreign currency generally will be U.S.-source ordinary income or loss. Special rules govern and specific elections are available to accrual method taxpayers to determine the U.S. dollar amount includible in income in the case of taxes withheld in a foreign currency. Accrual basis taxpayers are urged to consult their own tax advisers regarding the requirements and elections applicable in this regard.

Subject to applicable limitations, Dutch taxes withheld from a distribution paid to you at a rate not exceeding the rate provided in the U.S./NL Income Tax Treaty will be eligible for credit against your U.S. federal income tax liability. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For this purpose, dividends distributed by us with respect to the common shares generally will constitute “passive category income” or in the case of certain U.S. holders, “general category income”. The use of foreign tax credits is subject to complex rules and limitations. In lieu of a credit, a U.S. holder who itemizes deductions may elect to deduct all of such holder’s foreign taxes in the taxable year. A deduction does not reduce tax on a dollar-for-dollar basis like a credit, but the deduction for foreign taxes is not

128

subject to the same limitations applicable to foreign tax credits. You should consult your own tax advisor to determine whether and to what extent a credit would be available to you.

Certain non-corporate U.S. holders (including individuals) are eligible for reduced rates of U.S. federal income tax in respect of “qualified dividend income”. For this purpose, “qualified dividend income” generally includes dividends paid by a non-U.S. corporation if, among other things, the U.S. holders meet certain minimum holding period and other requirements and the non-U.S. corporation satisfies certain requirements, including either that (i) the shares of the non-U.S. corporation are readily tradable on an established securities market in the United States, or (ii) the non-U.S. corporation is eligible for the benefits of a comprehensive income tax treaty with the United States (such as the U.S./NL Income Tax Treaty) which provides for the exchange of information. We currently believe that dividends paid by us with respect to our common shares should constitute “qualified dividend income” for U.S. federal income tax purposes; however, this is a factual matter and subject to change. You are urged to consult your own tax advisor regarding the availability to you of a reduced dividend tax rate in light of your own particular situation. A dividends-received deduction will not be allowed with respect to dividends paid by us to corporate U.S. holders.

Sale, Exchange or Other Disposition of Common Shares

Upon a sale, exchange or other disposition of common shares, you generally will recognize capital gain or loss in an amount equal to the difference between the amount realized and your tax basis in the common shares, as determined in U.S. dollars. This gain or loss generally will be U.S.-source gain or loss, and will be treated as long-term capital gain or loss if you have held the common shares for more than one year. If you are an individual, capital gains generally will be subject to U.S. federal income tax at preferential rates if specified minimum holding periods are met. The deductibility of capital losses is subject to significant limitations.

Net Investment Income Tax

Certain U.S. holders that are individuals, estates or trusts and whose income exceeds certain thresholds generally will be subject to a 3.8% tax on “net investment income”, including, among other things, dividends on, and gains from the sale or other taxable disposition of, our common shares, subject to certain limitations and exceptions. You should consult your own tax advisor regarding the effect, if any, of such tax on your ownership and disposition of our common shares.

Passive Foreign Investment Company Status

We believe that we should not be classified as a passive foreign investment company (a “PFIC”) for U.S. federal income tax purposes for the year ended December 31, 2023 and we do not expect to become a PFIC in the foreseeable future. This conclusion is a factual determination that must be made annually at the close of each taxable year and therefore we can provide no assurance that we will not be a PFIC in our current or any future taxable year. If we were to be characterized as a PFIC for any taxable year, the tax on certain distributions on our common shares and on any gains realized upon the disposition of common shares may be materially less favorable than as described herein. In addition, if we were a PFIC in a taxable year in which we were to pay dividends or the prior taxable year, such dividends would not be “qualified dividend income” (as described above) and would be taxed at the higher rates applicable to other items of ordinary income. You should consult your own tax advisor regarding the application of the PFIC rules to your ownership of our common shares.

U.S. Information Reporting and Backup Withholding

Dividend payments with respect to our common shares and proceeds from the sale, exchange, retirement or other disposition of our common shares may be subject to information reporting to the U.S. Internal Revenue Service (the “IRS”) and possible U.S. backup withholding. Backup withholding will not apply to you, however, if you furnish a correct taxpayer identification number and make any other required certification, or if you are otherwise exempt from backup withholding. U.S. persons required to establish their exempt status generally must provide certification on IRS Form W-9. Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against your U.S. federal income tax liability, and you may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund with the IRS and furnishing any required information.

129

In addition, U.S. holders should be aware of annual reporting requirements with respect to the holding of certain foreign financial assets, including our common shares that are not held in an account maintained by certain types of financial institutions, if the aggregate value of all of such assets exceeds $50,000 (or $100,000 for married couples filing a joint return). You should consult your own tax advisor regarding the application of the information reporting and backup withholding rules to our common shares and the application of the annual reporting requirements to your particular situation.

Item 11.    Quantitative and Qualitative Disclosures About Market Risk

We are exposed to changes in financial market conditions in the normal course of business due to our operations in different foreign currencies and our ongoing investing and financing activities. Market risk is the uncertainty to which future earnings or asset/liability values are exposed due to operating cash flows denominated in foreign currencies and various financial instruments used in the normal course of operations. The major financial risks to which we are exposed are the foreign exchange risks related to the fluctuations of the U.S. dollar exchange rate compared to the Euro and the other major currencies in which costs are incurred, the variation of the interest rates and the risks associated to the investments of our available cash. We have established policies, procedures and internal processes governing our management of market risks and the use of financial instruments to manage our exposure to such risks.

Our interest income (expense), net, as reported in our consolidated statements of income, is the balance between interest income received from our cash and cash equivalents, short-term deposits and marketable securities and interest expense on our financial liabilities, including bank fees (including fees on committed credit lines or on the sale without recourse of receivables, if any). Our interest income is dependent upon fluctuations in interest rates, mainly in U.S. dollars and Euros, since we invest primarily on a short-term basis; any increase or decrease in the market interest rates would mean an equivalent increase or decrease in our interest income. See “Item 5. Operating and Financial Review and Prospects — Impact of Changes in Interest Rates”.

We place our cash and cash equivalents, or a part of it, with financial institutions with at least a single “A” long-term rating from two of the major rating agencies, meaning at least A3 from Moody’s and A- from S&P or Fitch, or better, invested as short-term deposits and Government debt securities and, as such, we are exposed to the fluctuations in the market interest rates on our placement and our cash, which can have an impact on our consolidated financial statements. We manage the credit risks associated with financial instruments through credit approvals, investment limits and centralized monitoring procedures but do not normally require collateral or other security from the parties to the financial instruments. As of December 31, 2023, the marketable securities have a value of $1,731 million. They are classified as available-for-sale and are reported at fair value. This fair value measurement corresponds to a Level 1 fair value hierarchy measurement. The estimated value of these securities could further decrease in the future as a result of credit market deterioration and/or other downgrading.

We do not anticipate any material adverse effect on our financial position, results of operations or cash flows resulting from the use of our instruments in the future. There can be no assurance that these strategies will be effective or that transaction losses can be minimized or forecasted accurately.

The information below summarizes our market risks associated with cash and cash equivalents, short-term deposits, marketable securities and debt obligations as of December 31, 2023. The information below should be read in conjunction with Note 15 and Note 26 to our Consolidated Financial Statements.

Disclosure Controls and Procedures

Evaluation

Our management, including the Chief Executive Officer and Chief Financial Officer, performed an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities and Exchange Act of 1934 (“Disclosure Controls”) as of the end of the period covered by this Form 20-F. Disclosure Controls are controls and procedures designed to reasonably assure that information required to be disclosed in our reports filed under the Securities and Exchange Act of 1934, such as this Form 20-F, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure Controls are also designed to reasonably assure that such information is accumulated and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

The evaluation of our Disclosure Controls included a review of the controls’ objectives and design, our implementation of the controls and their effect on the information generated for use in this Form 20-F. The components of our Disclosure Controls are also evaluated on an ongoing basis by our Corporate Audit Department, which reports directly to our Audit Committee. The overall goals of these various evaluation activities are to monitor our Disclosure Controls, and to modify them as necessary. Our intent is to maintain the Disclosure Controls as dynamic systems that change as conditions warrant.

Based on their evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this Form 20-F, our Disclosure Controls were effective.

Changes in Internal Control over Financial Reporting

There were no changes to our internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Securities and Exchange Act of 1934) that occurred during the period covered by this form 20-F that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Effectiveness of Controls

No system of internal control over financial reporting, including one determined to be effective, may prevent or detect all misstatements. It can provide only reasonable assurance regarding financial statement preparation and presentation. Also, projections of the results of any evaluation of the effectiveness of internal control over financial reporting into future periods are subject to inherent risk. The relevant controls may become inadequate due to changes in circumstances or the degree of compliance with the underlying policies or procedures may deteriorate.

Other Reviews

We have sent this Form 20-F to our Audit Committee and Supervisory Board, which had an opportunity to raise questions with our management and independent auditors before we filed it with the SEC.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles.

Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. 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. 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. See “Item 3. Key Information — Risk Factors”.

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2023, the end of our fiscal year. Management based its assessment on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control-Integrated Framework (2013). Management’s assessment included evaluation of such elements as the design and operating effectiveness of key financial reporting controls, process documentation, accounting policies and our overall control environment. Based on this assessment the management concluded that, as of December 31, 2023 our internal control over financial reporting was effective and the financial reporting is prepared on a going concern basis.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2023 has been audited by Ernst & Young AG, an independent registered public accounting firm, as stated in their report.

Report of Independent Registered Public Accounting Firm

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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.

137

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) 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 (3) 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.

Item 16C.    Principal Accountant Fees and Services

Our independent external auditors are elected at the AGM. At our AGM held in May 2015, Ernst & Young was first appointed as our independent external auditor for the 2016-2019 fiscal years. At our AGM held on June 17, 2020, our shareholders re-appointed Ernst & Young as our independent external auditor for the

138

2020-2023 fiscal years. The Supervisory Board will propose that Ernst & Young be re-appointed as our independent external auditor for the 2024-2025 fiscal years at our 2024 AGM. The following table presents the aggregate fees for professional audit services and other services rendered to us by Ernst & Young in 2023 and 2022.

In thousand of U.S. dollars	2023		Percentage of Total Fees		2022		Percentage of Total Fees

Audit Fees consist of fees billed for the annual audit of our Company’s Consolidated Financial Statements, the statutory audit of the financial statements of the Company’s subsidiaries and consultations on complex accounting issues relating to the annual audit. Audit Fees also include services that only our independent external auditor can reasonably provide, such as comfort letters and carve-out audits in connection with strategic transactions.

Audit-related services are assurance and related fees consisting of the audit of employee benefit plans, due diligence services related to acquisitions and certain agreed-upon procedures.

Tax Fees include fees billed for tax compliance services, including the preparation of original and amended tax returns and claims for refund; tax consultations, such as assistance in connection with tax audits and expatriate tax compliance.

Audit Committee Pre-approval Policies and Procedures

Our Audit Committee is responsible for selecting the independent registered public accounting firm to be employed by us to audit our financial statements, subject to ratification by the Supervisory Board and approval by our shareholders for appointment. Our Audit Committee also assumes responsibility (inter alia in accordance with Dutch law and the Dutch Corporate Governance Code) for the retention, compensation, oversight and termination of any independent external auditor employed by us. We adopted a policy (the “Policy”), which was approved in advance by our Audit Committee, for the pre-approval of audit and permissible non-audit services provided by our independent external auditors. The Policy defines those audit-related services eligible to be approved by our Audit Committee.

All engagements with our independent external auditors, regardless of amount, must be authorized in advance by our Audit Committee, pursuant to the Policy and its pre-approval authorization or otherwise.

The independent external auditors submit a proposal for audit-related services to our Audit Committee on a quarterly basis in order to obtain prior authorization for the amount and scope of the services. The independent external auditors must state in the proposal that none of the proposed services affect their independence. The proposal must be endorsed by the office of our Chief Financial Officer with an explanation of why the service is needed and the reason for sourcing it to the audit firm and validation of the amount of fees requested.

We do not intend to retain our independent external auditors for permissible non-audit services other than by exception and within a limited amount of fees, and the Policy provides that such services must be explicitly authorized by our Audit Committee.

The Chief Audit and Risk Executive is responsible for monitoring that the actual fees are complying with the pre-approval amount and scope authorized by our Audit Committee. During 2023, all services provided to us by Ernst & Young were approved by our Audit Committee pursuant to paragraph (c)(7)(i) of Rule 2-01 of Regulation S-X.

Item 16F.    Change in Registrant’s Certifying Accountant

Not applicable.

Item 16G.    Corporate Governance

As we have common shares listed on the NYSE, pursuant to SEC and NYSE rules, in this Item 16G we provide a concise summary of any significant ways in which our corporate governance practices differ from those followed by U.S. companies under NYSE listing standards.

As a Dutch company, we are subject to the Dutch Corporate Governance Code. We have summarized our policies and practices in the field of corporate governance in our Corporate Governance Charter, including our corporate organization, the remuneration principles which apply to our Managing and Supervisory Boards, our information policy and our corporate policies relating to business ethics and conflicts of interests. We are committed to informing our shareholders of any significant changes in our corporate governance policies and practices at our AGM. Along with our Supervisory Board charter (which also includes the charters of our Supervisory Board Committees) and our Code of Conduct, the current version of our Corporate Governance Charter is posted on our website (www.st.com), and these documents are available in print to any shareholder who may request them.

Below is a description of the significant ways our corporate governance practices as a Dutch company differ from those followed by U.S. companies listed on the NYSE:

140

•Because we are a Dutch company, the Audit Committee is an advisory committee to the Supervisory Board, which reports to the Supervisory Board, and our general meeting of shareholders appoints our statutory auditors. Our Audit Committee has established a charter outlining its duties and responsibilities with respect to, among others, the monitoring of our accounting, auditing, financial reporting and the appointment, retention and oversight of our external auditors. In addition, our Audit Committee has established procedures for the receipt, retention and treatment of complaints regarding accounting, internal accounting controls or auditing matters, and the confidential anonymous submission by our employees regarding questionable accounting or auditing matters.

•Pursuant to our Supervisory Board charter, the Supervisory Board is responsible for handling and deciding on potential reported conflicts of interests between the Company and members of the Supervisory Board, as well as the Managing Board. See “Item 7. Major Shareholders and Related Party Transactions”.

•Our Supervisory Board is carefully selected based upon the combined experience and expertise of its members. In fulfilling their duties under Dutch law, Supervisory Board members shall be guided by the interests of our Company and its business, and it shall take into account the relevant interests of all of our stakeholders (including our shareholders) and must act independently in their supervision of our management. Our Supervisory Board has adopted criteria to assess the independence of its members in accordance with corporate governance listing standards of the NYSE. Our Supervisory Board has on various occasions discussed Dutch corporate governance standards, the implementing rules and corporate governance standards of the SEC and of the NYSE, as well as other corporate governance standards. The Supervisory Board has determined, based on the evaluations by an ad hoc committee, the following independence criteria for its members: Supervisory Board members must not have any material relationship with STMicroelectronics N.V., or any of our consolidated subsidiaries, or our management. A “material relationship” can include commercial, industrial, banking, consulting, legal, accounting, charitable and familial relationships, among others, but does not include a relationship with direct or indirect shareholders.

We believe we are fully compliant with all material NYSE corporate governance standards, to the extent possible for a Dutch company listed on Euronext Paris, Borsa Italiana, as well as the NYSE.

Our consistent commitment to good corporate governance principles is evidenced by:

•Our corporate organization under Dutch law that entrusts our management to a Managing Board acting under the supervision and control of a Supervisory Board totally independent from the Managing Board. Members of our Managing Board and of our Supervisory Board are appointed and dismissed by our shareholders;

•Our early adoption of policies on important issues such as business ethics, anti-corruption and conflicts of interest and strict policies to comply with applicable regulatory requirements concerning financial reporting, insider trading and public disclosures;

•Our compliance with Dutch securities laws, because we are a company incorporated under the laws of The Netherlands, as well as our compliance with American, French and Italian securities laws, as applicable, because our shares are listed in these jurisdictions, in addition to our compliance with the corporate, social and financial laws applicable to our subsidiaries in the countries in which we do business;

•Our broad-based activities in the field of corporate social responsibility, encompassing environmental, social, health, safety, educational and other related issues including our corporate governance statement which evidences our policy objectives with respect to diversity as well as the results of implementing our diversity policy for the year ended December 31, 2023;

•Our implementation of an ethics hotline (operated by an independent third-party). We encourage everyone, including external business partners, to express, in good faith, any concerns they might have regarding possible violations of our Code of Conduct, the Company’s policies, or the law through, amongst other things, our Code of Conduct, dedicated intranet web pages and our ST

141

Integrity App. Our 'speak-up' policy is communicated to all employees and includes an independent multilingual ethics hotline;

•Our Corporate Ethics Committee and Local Ethics Committees, whose mandate is to provide support to our management in its efforts to foster a business ethics culture consistent across regions, functions and organizations;

•Our Chief Compliance Officer, who reports to our Chief Executive Officer, also acts as Executive Secretary to our Supervisory Board; and

•Our Executive Vice President, Chief Audit and Risk Executive, who reports directly to our Audit Committee for Corporate Audit activities and directly to the Chief Financial Officer for Enterprise Risk Management and Resilience (business continuity and crisis management) are also, in conjunction with the Chief Compliance Officer, responsible for the management of the ethics hotline.

No member of the Supervisory Board or Managing Board has been (i) subject to any convictions in relation to fraudulent offenses during the five years preceding the date of this Form 20-F, (ii) no member has been associated with any company in bankruptcy, receivership or liquidation in the capacity of member of the administrative, management or supervisory body, partner with unlimited liability, founder or senior manager in the five years preceding the date of this Form 20-F or (iii) subject to any official public incrimination and/or sanction by statutory or regulatory authorities (including professional bodies) or disqualified by a court from acting as a member of the administrative, management or supervisory bodies of any issuer or from acting in the management or conduct of the affairs of any issuer during the five years preceding the date of this Form 20-F.

Item 16I. Disclosure Regarding Foreign Jurisdictions that Prevent Inspections

Not applicable.

Item 16J. Insider Trading Policies

Not applicable. We will be required to comply with disclosure requirements under this item 16J for the fiscal year ending on December 31, 2024.

Item 16K. Cybersecurity

As a company operating globally in the semiconductor market, we are exposed to risks, including cybersecurity risks. As of December 31, 2023, we are not aware of any previous cybersecurity incidents that have materially affected or are reasonably likely to materially affect our service, systems or business, however, for a full description of our risk factors, please refer to “Item 3. Key Information - Risk Factors”.

Our overall risk approach is managed by our Chief Audit & Risk Executive, Mr. Franck Freymond, under the direct responsibility of our Managing Board and the oversight of our Supervisory Board.

Our embedded approach to enterprise risk management (“ERM”) is formalized in a specific policy and is aligned with ISO 31000 (Risk Management). This enables us to:

•set and enable our Company strategy, manage our performance, and capitalize on opportunities; and

•systematically identify, evaluate and treat specific risk scenarios.

142

Our ERM improvement roadmap includes, in particular, deploying our risk framework which is based on the following principles:

•taking into consideration the interests of our stakeholders;

•addressing uncertainty explicitly;

•pragmatic and tailored to us;

•integral part of our processes and decision-making;

•proactive, structured, dynamic, iterative and responsive to change; and

•based on the best available information.

Our risk governance, including our governance of cybersecurity risks, is described in the following chart:

Risk owners (members of our Senior Management) are appointed for each priority risk area to develop risk response plans, adapt to changing external conditions and enhance monitoring capabilities. The risk response plans are regularly reviewed by our Executive Committee and periodically discussed with our Supervisory Board and Audit Committee.

143

The embedded ERM process takes a holistic view, combining both company-wide top-down and bottom-up perspectives, to ensure that specific risk scenarios are addressed at the right level. The process is implemented as described in the following chart:

As part of the overall risk framework, we have also designed and implemented a dedicated resilience framework which provides a consistent approach to address risks of potential disruptions of our resources, including potential cybersecurity-attacks. In 2023, we continued to enhance a company-specific methodology underpinning a global dashboard: a range of relevant indicators based on internal or external standards, covering dimensions such as exposure to natural hazards, loss prevention characteristics, facilities robustness, equipment modernization and redundancy, IT infrastructure quality and cyber protection. For every significant site, those indicators are compiled in our “site resilience index”, which is updated on a quarterly basis. Annually, site management teams prepare and update a site improvement plan accordingly.

Cybersecurity risk management is an integral part of the overarching risk framework and seeks to identify and address fast-evolving cybersecurity threats. The management of cybersecurity risks are governed by the Executive Committee and receives regular oversight from the Audit Committee as a standing item. Please see “Item 6. Directors, Senior Management and Employees” for a description of the biographies of our Executive Committee and Audit Committee members.

We have a specialized Information Security team within the wider Digital Transformation and Information Technology team of the Company. The Information Security team covers the following:

•program definition and steering;

•framework, which include third-party security;

•awareness and training campaigns;

•architecture and engineering;

•business applications;

•R&D solutions;

144

•manufacturing and industrial solutions;

•IT infrastructures;

•information security operations (risk-based vulnerability management, privileged access management); and

•detection and reactions to information security incidents, as part of the wider crisis management process.

In particular, within our Information Security team, the Cyber Security Incident Response Team monitor on a continuous basis the evolving cyber threats, and detect and analyze incidents. Based on their initial assessments, any significant risk is escalated and would, if required, trigger the assembly of a Corporate Crisis Team ("CCT"). This CCT would lead the Company response (e.g. containment, forensic investigation, system restoration, and any associated business impact). The CCT would periodically inform the Executive Committee of any developments, and the Executive Committee would in-turn keep the Audit Committee and Supervisory Board informed.

In addition, we have recently created a Third-Party Management function within our procurement department, which will take into consideration cybersecurity risks in the overall management of third parties.

The maturity of our overall risk framework design and implementation, of which includes cybersecurity risks, is periodically audited by a leading independent organization. This was last performed in 2022, confirming a significant improvement in maturity compared to the previous such audit performed in 2017. In 2023, additional audits by a leading independent organization were completed and focused on the following specific areas:

•Maturity assessment of the design and implementation of our resilience framework, confirming its current level of maturity;

•Dedicated review of our cyber crisis playbook.

In addition, we have been ISO 22301 (Security and Resilience) certified since 2016. Throughout 2023, our continuous improvements have been subjected to both internal audits and external surveillance audits from the certification body. We have also been certified ISO SAE 21434 (Road Vehicles – Cybersecurity Engineering) since 2022 confirming that we established a certified management system and governance which meets and complies with the requirements of the automotive industry in the field of cyber security process management within product development phases.

Report of Independent Registered Public Accounting Firm

To the Supervisory Board and Stockholders of STMicroelectronics N.V.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of STMicroelectronics N.V. (the Company) as of December 31, 2023 and 2022, and the related consolidated statements of income, comprehensive income, equity and cash flows for each of the three years in the period ended December 31, 2023, and the related notes and financial statements schedule on page S-1 (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 22, 2024 expressed an unqualified opinion thereon.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the 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 audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits 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. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

F-1

Recoverability of deferred tax assets

Description of the Matter:     At December 31, 2023 the Company reports deferred tax assets of $592 million. As explained in note 2.7 to the consolidated financial statements, the Company performs an evaluation of the likelihood that future taxable income will be generated in an amount sufficient to utilize such deferred tax assets prior to their expiration, and, after having considered positive and negative available evidence, records a valuation allowance for any deferred tax assets when it is more likely than not they will not be realized.

Assessing the recoverability of deferred tax assets involves significant judgement and estimates in relation to the prospective financial information used by management in order to assess future taxable income, which are dependent on the outcome of future events.

How We Addressed the Matter

In Our Audit:    We obtained an understanding, evaluated the design and tested the operating effectiveness of management’s controls around, among others: the calculation of the gross amount of deferred tax assets recorded, the preparation of the prospective financial information used to determine the Company’s future taxable income and the assessment of valuation allowance needed for deferred tax assets not deemed recoverable.

We involved tax professionals to assist with our procedures in evaluating management's weighting of available positive and negative evidence used in their assessment of the realizability of deferred tax assets. Among other procedures, we evaluated the timing of the reversal of the temporary differences and management’s prospective financial information used to determine future taxable income and its consistency with current transfer pricing policies. We compared management’s projections with the actual results of prior periods, as well as management’s consideration of current and expected industry and economic trends.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(In millions of U.S. dollars, except share and per-share amounts)

1.THE COMPANY

STMicroelectronics N.V. (the “Company”) is registered in the Netherlands with its corporate legal seat in Amsterdam, the Netherlands, and its corporate headquarters located in Geneva, Switzerland.

The Company is a global semiconductor company that designs, develops, manufactures and markets a broad range of products, including discrete and general purpose components, application-specific integrated circuits (“ASICs”), full-custom devices and semi-custom devices and application-specific standard products (“ASSPs”) for analog, digital and mixed-signal applications. In addition, the Company participates in the manufacturing value chain of smartcard products, which includes the production and sale of both silicon chips and smartcards.

2.    ACCOUNTING POLICIES

The accounting policies of the Company conform to accounting principles generally accepted in the United States of America (“U.S. GAAP”). All balances and values in the current and prior periods are in millions of U.S. dollars, except share and per-share amounts. Under Article 35 of the Company’s Articles of Association, the financial year extends from January 1 to December 31, which is the period-end of each fiscal year.

2.1     Basis of presentation and consolidation

The Company's consolidated financial statements include the assets, liabilities, results of operations and cash flows of its wholly-owned and majority-owned subsidiaries, after elimination of intercompany transactions and balances. Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are deconsolidated from the date that control ceases.

The Company assesses each investment in equity securities to determine whether the investee is a Variable Interest Entity (“VIE”). The Company consolidates the VIEs for which the Company is determined to be the primary beneficiary. The primary beneficiary of a VIE is the party that: (i) has the power to direct the most significant activities of the VIE and (ii) is obligated to absorb losses or has the rights to receive returns that would be considered significant to the VIE.

When the Company owns some, but not all, of the voting stock of a consolidated entity, the shares held by third parties represent a noncontrolling interest. The consolidated financial statements are prepared based on the total amount of assets and liabilities and income and expenses of the consolidated subsidiaries. However, the portion of these items that does not belong to the Company’s shareholders is reported in the line “Noncontrolling interest” of the consolidated financial statements.

2.2     Use of estimates

The preparation of consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions. The primary areas that require significant estimates and judgments by management include, but are not limited to:

•sales allowances for discounts, price protection, product returns and other rebates,

•inventory obsolescence reserves and normal manufacturing capacity thresholds to determine costs capitalized in inventory,

•recognition and measurement of loss contingencies,

•valuation at fair value of assets acquired and liabilities assumed on business acquisitions, and measurement of any contingent consideration,

F-8

•annual and trigger-based impairment review of goodwill and intangible assets, as well as the assessment of events which could trigger impairment testing on tangible assets,

•assessment of the Company’s long-lived assets economic useful lives,

•assumptions used in measuring expected credit losses and impairment charges on financial assets,

•assumptions used in assessing the number of awards expected to vest on stock-based compensation plans,

•assumptions used in calculating net defined pension benefit obligations and other long-term employee benefits,

•determination of the amount of tax expected to be paid and tax benefit expected to be received, including deferred income tax assets, valuation allowance and provisions for uncertain tax positions and claims.

The Company bases the estimates and assumptions on historical experience and on various other factors such as market trends, market information used by market participants and the latest available business plans that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. While the Company regularly evaluates its estimates and assumptions, the actual results experienced by the Company could differ materially and adversely from those estimates.

2.3     Foreign currency

The U.S. dollar is the reporting currency of the Company. The U.S. dollar is the currency of the primary economic environment in which the Company operates since the worldwide semiconductor industry uses the U.S. dollar as a currency of reference for actual pricing in the market. Furthermore, the majority of the Company’s transactions are denominated in U.S. dollars, and revenues from external sales in U.S. dollars largely exceed revenues in any other currency. However, certain significant costs are incurred in the countries of the Eurozone and other non-U.S. dollar currency areas.

The functional currency of each subsidiary of the Company is either the local currency or the U.S. dollar, depending on the basis of the economic environment in which each subsidiary operates. Foreign currency transactions, including operations in local currency when the U.S. dollar is the functional currency, are measured into the functional currency using the prevailing exchange rate. Foreign exchange gains and losses resulting from the re-measurement at reporting date of monetary assets and liabilities denominated in currencies other than the functional currency are recognized in the line “Other income and expenses, net” of the consolidated statements of income.

For consolidation purposes, the results and financial position of the subsidiaries whose functional currency is different from the U.S. dollar are translated into the reporting currency as follows:

(a)assets and liabilities for each consolidated balance sheet presented are translated into U.S. dollars using exchange rates at the balance sheet dates;

(b)income and expenses for each consolidated statement of income presented are translated into U.S dollars using the monthly exchange rates;

(c)the resulting exchange differences are reported as Currency Translation Adjustments (“CTA”), a component of “Other comprehensive income (loss)” in the consolidated statements of comprehensive income.

F-9

2.4     Cash and cash equivalents

Cash and cash equivalents include cash on hand, deposits held at call with external financial institutions and other short-term highly liquid investments with effective maturities of three months or less. They are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates.

Short-term deposits representing cash equivalents with maturity beyond three months and below one year are reported as current assets in the line “Short-term deposits” of the consolidated balance sheets.

2.5     Trade accounts receivable

Trade accounts receivable are amounts due from customers for goods sold and services rendered to third parties in the ordinary course of business. The Company uses a lifetime expected losses allowance for all trade receivables. The allowance includes reasonable assumptions about future credit trends. The historical loss rates are adjusted to reflect current and forward-looking information on macro-economic factors affecting the ability of the Company’s customers to settle the receivables. Adjustments to the expected credit losses allowance are reported on the line “Selling, general and administrative expenses” in the consolidated statements of income and write-offs, if any, are recorded against the expected credit losses allowance.

In the event of transfers of receivables such as factoring, the Company derecognizes the receivables only to the extent that the Company has surrendered control over the receivables in exchange for a consideration other than beneficial interest in the transferred receivables.

2.6     Inventories

Inventories are stated at the lower of cost and net realizable value. Actual cost is based on an adjusted standard cost, which approximates cost on a first-in, first-out basis for all categories of inventory (raw materials, work-in-process, finished products). Actual cost is therefore dependent on the Company’s manufacturing performance and is based on the normal utilization of its production capacity. In case of underutilization of manufacturing facilities, the costs associated with unused capacity are not included in the valuation of inventories but charged directly to cost of sales. Net realizable value is based upon the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation.

Inventory reserve is estimated for excess uncommitted inventory based on historical sales data, order backlog and production plans. The Company performs, on a continuous basis, write-offs of inventories, which have the characteristics of slow-moving, old production dates and technical obsolescence. The Company evaluates its inventory to identify obsolete or slow-selling items, as well as inventory that is not of saleable quality and records a specific reserve if the Company estimates the inventory will eventually be written off.

2.7     Income taxes

Income tax for the period comprises current and deferred income tax. Income tax expense represents the income tax expected to be paid related to the current year taxable profit in each tax jurisdiction. Deferred income tax is recognized for all temporary differences arising between the tax bases of assets and liabilities and their carrying amount in the consolidated financial statements. Deferred tax assets are also recognized on temporary differences arising from tax losses carried forward and tax credits. Deferred tax liabilities are not recognized on the initial recognition of goodwill as a result of a business combination. Deferred income tax is determined using tax rates and laws that are enacted at the balance sheet date and are expected to apply when the related deferred income tax asset is realized or the deferred income tax liability is settled. The effect on deferred tax assets and liabilities from changes in tax laws and tax rates is recognized on the line “Income tax expense” in the consolidated statements of income in the period in which the law is enacted. Deferred income tax assets are recognized in full but the Company assesses whether future taxable profit will be available against which temporary differences can be utilized. A valuation allowance is provided for deferred tax assets when management considers it is more likely than not that they will not be realized.

The Company recognizes a deferred tax liability on undistributed earnings of subsidiaries when there is a presumption that taxable earnings will be remitted to the parent. A deferred tax asset is recognized on

F-10

compensation for the grant of stock awards to the extent that such charge constitutes a temporary difference in the subsidiaries’ local tax jurisdictions. Changes in the stock price do not result in any adjustments to the deferred tax asset prior to vesting.

At each reporting date, the Company assesses all significant income tax positions in all tax jurisdictions to determine any uncertain tax positions. The Company uses a two-step process for the evaluation of uncertain tax positions. The first step consists in assessing whether the tax benefit must be recognized. The second step consists in measuring the amount of tax benefit to be recognized on each uncertain tax position. In step 1 (recognition), the Company assesses whether a tax position, based solely on its technical merits, is more likely than not to be sustained upon examination. Only tax positions with a sustainability threshold higher than 50% are recognized. In Step 2 (measurement), the Company determines the amount of recognizable tax benefit. The measurement methodology is based on a “cumulative probability” approach, resulting in the recognition of the largest amount that is greater than 50% likely of being realized upon settlement with the taxing authority. The Company accrues for interest and penalties on uncertain tax liabilities reported on the consolidated balance sheets. Interests and penalties are classified as components of income tax expense in the consolidated statements of income.

2.8     Business combinations and goodwill

The acquisition method of accounting is applied to all business combinations. The identifiable assets acquired, liabilities assumed, and equity instruments issued are measured at acquisition date fair value. Any contingent consideration is recorded at acquisition date fair value and remeasured at each reporting date. Acquisition-related transaction costs and restructuring costs related to the acquired business are expensed as incurred. Acquired in-process research and development (“IPR&D”) is capitalized and recorded as an intangible asset at acquisition date, subject to impairment testing until the research or development is completed. The excess of the consideration transferred over the acquisition-date fair value of the identifiable assets acquired and liabilities assumed, net of related deferred tax impacts, is recorded as goodwill. In case of a bargain purchase, the Company reassesses whether it has correctly identified all of the assets acquired and all of the liabilities assumed, the noncontrolling interest in the acquiree, if any, the Company’s previously held equity interest in the acquiree, if any, and the consideration transferred. If after this review, a bargain purchase is still indicated, it is recognized in earnings attributable to parent company stockholders. The purchase of additional interests in a partially owned subsidiary is treated as an equity transaction as well as all transactions concerning the sale of subsidiary stock or the issuance of stock by the partially owned subsidiary, assuming there is no change in control of the subsidiary. In the case of a sale of subsidiary shares, whereby the Company no longer maintains control of the subsidiary, the Company recognizes a gain or loss in earnings.

Goodwill is carried at cost less accumulated impairment losses, if any. Goodwill is not amortized but is tested for impairment at least annually, and more frequently whenever events or changes in circumstances indicate that the carrying amount of goodwill may not be recoverable. Goodwill subject to potential impairment is tested at the reporting unit level. The impairment test determines whether the fair value of each reporting unit under which goodwill is allocated is lower than the total carrying amount of relevant net assets allocated to such reporting unit, including its allocated goodwill. The Company records an impairment loss on goodwill when a reporting unit’s carrying value exceeds its fair value. Significant management judgments and estimates are used in forecasting the future discounted cash flows associated with the reporting unit, including: the applicable industry’s sales volume forecast and selling price evolution, the reporting unit’s market penetration and its revenues evolution, the market acceptance of certain new technologies and products, the relevant cost structure, the discount rates applied using a weighted average cost of capital and the perpetuity rates used in calculating cash flow terminal values.

2.9     Intangible assets with definite useful lives

Intangible assets subject to amortization include intangible assets purchased from third parties recorded at cost and intangible assets acquired in business combinations initially recorded at fair value. Amortization begins when the intangible asset is available for its intended use. Amortization reflects the pattern in which the asset’s economic benefits are consumed, which usually consists in applying the straight-line method to allocate the cost of the intangible assets over their estimated useful lives.

The carrying value of intangible assets with definite useful lives is evaluated whenever changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for

F-11

the amount by which the asset’s carrying amount exceeds its fair value. The Company evaluates the remaining useful life of an intangible asset at each reporting date to determine whether events and circumstances warrant a revision to the remaining period of amortization.

Technologies and licenses

Separately acquired technologies and licenses are recorded at historical cost. Technologies and licenses acquired in a business combination are initially recognized at acquisition date fair value. Technologies and licenses have a useful life which usually ranges from 3 to 11 years and are carried at cost less accumulated amortization and impairment losses, if any.

Computer software

Separately acquired computer software is recorded at historical cost. Costs associated with maintaining computer software programs are expensed as incurred and reported as “Cost of sales”, “Selling, general and administrative expenses”, or “Research and development expenses” in the consolidated statements of income according to their intended use. The capitalization of costs for internally generated software developed by the Company for its internal use begins when the preliminary project stage is completed and when the Company, implicitly or explicitly, authorizes and commits to funding a computer software project. It must be probable that the project will be completed and will be used to perform the function intended. Amortization of computer software begins when the software is available for its intended use and is calculated using the straight-line method over the estimated useful life, which does not exceed 4 years.

2.10     Property, plant and equipment

Property, plant and equipment are stated at historical cost, net of accumulated depreciation and any impairment losses. Property, plant and equipment acquired in a business combination are initially recognized at acquisition date fair value. Major additions and improvements are capitalized, while minor replacements and repairs are expensed and reported as “Cost of sales”, “Selling, general and administrative expenses”, or “Research and development expenses” in the consolidated statements of income according to their intended use.

Land is not depreciated. Depreciation on fixed assets is computed using the straight-line method over their estimated useful lives, as follows:

Buildings	33 years
Facilities and leasehold improvements	5-10 years
Machinery and equipment	2-10 years
Computer and R&D equipment	3-6 years
Other	2-5 years

The Company also evaluates, and adjusts if appropriate, the assets’ useful lives.

Property, plant and equipment are periodically reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or a group of assets may not be recoverable. Several impairment indicators exist for making this assessment, such as: restructuring plans, significant changes in the technology, market, economic or legal environment in which the Company operates, available evidence of obsolescence of the asset, or indication that its economic performance is, or will be, worse than expected. In determining the recoverability of assets to be held and used, the Company initially assesses whether the carrying value of the tangible assets or group of assets exceeds the undiscounted cash flows associated with these assets. If exceeded, the Company then evaluates whether an impairment charge is required by determining if the asset’s carrying value also exceeds its fair value. This fair value is normally estimated by the Company based on independent market appraisals or the sum of discounted future cash flows, using market assumptions such as the utilization of the Company’s fabrication facilities and the ability to upgrade such facilities, change in the selling price and the adoption of new technologies. Any impairment loss is reported on the same income statement line as the depreciation expense recorded on the impaired group of assets, except in case of closure of operating sites or major restructuring plans and reorganizations. In such case, any impairment loss is reported on the line “Impairment, restructuring charges and other related closure costs” in the consolidated statements of income.

F-12

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are included in “Other income and expenses, net” in the consolidated statements of income.

The Company did not hold any significant assets held for sale as of December 31, 2023 and December 31, 2022.

2.11     Leases

A lease contract is a contract, or part of a contract, that conveys the right to control the use of an identified asset for a period of time in exchange for consideration. If a lease is identified, classification between finance or operating is determined at lease commencement. Most leases entered by the Company are operating leases. Operating lease liabilities are recognized at the present value of the future lease payments at the lease commencement date. The rate implicit in the lease should be used as a discount rate whenever that rate is readily determinable. In most cases, this rate is not readily determinable and therefore, the Company uses its incremental borrowing rate, which is derived from information available at the lease commencement date. The Company considers its recent debt issuances as well as publicly available data for instruments with similar characteristics when calculating its incremental borrowing rates. Operating lease right-of-use assets are based on the corresponding lease liability adjusted for any lease payments made at or before commencement, initial direct costs, and lease incentives.

Right-of-use assets are included in the line “Property, plant and equipment, net” of the consolidated balance sheets. Operating lease liabilities due within one year are included in the line “Other payables and accrued liabilities”, while non-current operating lease liabilities are included in the line “Other long-term liabilities” of the Company’s consolidated balance sheets. Operating lease expenses are recognized in the consolidated statements of income, on a straight-line basis since the lease commencement date over the lease period and reported as “Cost of sales”, “Selling, general and administrative expenses”, or “Research and development expenses”, according to the intended use of the leased asset.

Finance lease liabilities due within one year are included in the line “Short-term debt”, while non-current finance lease liabilities are included in the line “Long-term debt” of the Company’s consolidated balance sheets. Right-of-use assets for finance leases are depreciated on a straight-line basis since the lease commencement date over the lease period or the estimated useful life of the leased asset in case of transfer of ownership or purchase option that is reasonably certain to be exercised. The depreciation expense is reported as “Cost of sales”, “Selling, general and administrative expenses”, or “Research and development expenses”, according to the intended use of the leased asset.

Certain lease contracts contain options to extend the lease. On these contracts, the Company estimates the lease term by including the extended duration when it is reasonably certain for the Company to exercise that option. In addition, for short-term leases, defined as leases with a term of twelve months or less, the Company elected the practical expedient to not recognize an associated lease liability and right-of-use asset. The short-term lease election is made at the commencement date only. Additionally, lease contracts with a sum of lease payments not exceeding $5,000 are excluded from recognition on the consolidated balance sheet.

The right-of-use asset is a non-monetary asset while the lease liability is a monetary liability. When accounting for a lease that is denominated in a foreign currency, the lease liability is remeasured using the current exchange rate, while the right-of-use asset is measured using the historical exchange rate as of the commencement date.

The Company does not separate lease and non-lease components and instead accounts for each separate lease component and the non-lease components associated with that lease component as a single lease component.

Variable lease payments that depend on an index or a rate are included in the lease payments and are measured using the prevailing index or rate at the measurement date. Changes to index and rate-based variable lease payments are recognized in earnings in the period of the change.

2.12     Loss contingencies

In determining loss contingencies, the Company considers the likelihood of the incurrence of a liability as well as the ability to reasonably estimate the amount of such loss or liability. An estimated loss from a loss contingency is accrued when information available indicates that it is probable that a liability has been incurred at the date of the consolidated financial statements and when the amount of the loss can be reasonably estimated.

F-13

2.13     Long-term debt

(a)Convertible debt

On January 1, 2022, the Company adopted the new guidance on distinguishing liabilities from equity by applying the modified retrospective approach, with the impact upon transition recorded in retained earnings for instruments outstanding as of the date of adoption of the new guidance. Prior to the new guidance, components of convertible debt instruments that may be settled in cash upon conversion based on a net-share settlement basis were accounted for separately as long-term debt and equity when the conversion feature of the convertible bonds constituted an embedded equity instrument. When an equity instrument was identified, proceeds from issuance were allocated between debt and equity by measuring first the liability component and then determining the equity component as a residual amount. The liability component was measured as the fair value of a similar non-convertible debt, which resulted in the recognition of a debt discount. In subsequent periods, the Company amortized the debt discount through earnings in the line “Interest income (expense), net” of the consolidated statements of income, using the effective interest method, based on the contractual maturity of the debt. The equity component, reported on the line “Additional paid-in capital” of the consolidated statement of equity, was not remeasured. Deferred taxes were recognized on the difference between the carrying amount of the liability component and its tax basis. In case of conversion from the bondholders, the fair value of the consideration transferred was allocated between the liability component and the equity component. The difference between the carrying amount of the debt at the settlement date and the fair value of the debt component was recorded in earnings as a loss on debt extinguishment and reported in the line “Loss on financial instruments, net” of the consolidated statements of income. The liability component was measured as the fair value of a similar non-convertible debt prior to settlement. The reacquired equity component was recorded in equity and reported on the line “Additional paid-in capital” of the consolidated statement of equity.

The new accounting guidance adopted on January 1, 2022 has eliminated the cash conversion model described above. At initial recognition, total cash proceeds received at issuance are reported as financial debt and no equity conversion instrument is recorded separately in equity. On subsequent periods, the carrying value of the convertible debt is incremented up to its nominal value over the amortization pattern of any unamortized debt discount and issuance costs.

Debt issuance costs are reported as a deduction of debt. They are subsequently amortized through earnings on the line “Interest income (expense), net” of the consolidated statements of income, using the effective interest rate method.

(b)Bank loans

Bank loans and non-convertible senior bonds are recognized at the amount of cash proceeds received, net of debt issuance costs incurred. They are subsequently reported at amortized cost; any difference between the proceeds (net of debt issuance costs) and the principal amount is recognized through earnings on the line “Interest income (expense), net” of the consolidated statements of income over the period of the borrowings using the effective interest method.

2.14     Employee benefits

(a) Pension obligations

The Company sponsors various pension schemes for its employees. These schemes conform to local regulations and practices in the countries in which the Company operates. Such plans include both defined benefit and defined contribution plans. For defined benefit pension plans, the liability recognized in the consolidated balance sheets is the present value of the defined benefit obligation at the balance sheet date less the fair value of plan assets. The funded status of the defined benefit plans is calculated as the difference between plan assets and the projected benefit obligations. Estimates are used in determining the assumptions incorporated in the calculation of the pension obligations, which is supported by input from independent actuaries. Actuarial gains and losses arising from changes in actuarial assumptions are recognized in “Accumulated other comprehensive income (loss)” in the consolidated statements of equity and are charged or credited to earnings over the employees’ average remaining service period using the corridor amortization method. Past service costs are recognized in earnings on the line “Other components of pension benefit costs” of the consolidated statements of income if the changes to the pension scheme are not conditional on the employees remaining in service for a specified period. Other past service costs are recognized in “Accumulated other comprehensive income (loss)”

F-14

in the consolidated statements of equity and are amortized on a straight-line basis over the average remaining service period. The net periodic benefit cost of the year is determined based on the assumptions used at the end of the previous year.

The service cost component of net periodic benefit costs is presented in the same income statement line as other employee compensation costs arising from services rendered during the period. The other components of the net periodic benefit cost are presented separately, outside operating income, on the line “Other components of pension benefit costs” of the consolidated statements of income. These elements include: interest cost; expected return on plan assets; amortization of transition (asset) obligation; amortization of prior service cost; amortization of net (gain) loss; (gain) loss recognized due to curtailment or settlement and; cost of special termination benefits.

For defined contribution pension plans, the Company pays contributions to publicly or privately administered pension insurance plans on a mandatory, contractual or voluntary basis. The Company has no further payment obligations once the contributions have been paid. The contributions are recognized as employee benefit expense when they are due. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in the future payments is available.

(b) Termination benefits

Termination benefits are payable when an employee is involuntarily terminated, or whenever an employee accepts voluntary termination in exchange for termination benefits. For the accounting treatment and timing of recognition of involuntary termination benefits, the Company distinguishes between one-time termination benefit arrangements and ongoing termination benefit arrangements. A one-time termination benefit arrangement is established by a termination plan and applies to a specified termination event. One-time involuntary termination benefits are recognized as a liability when the termination plan meets certain criteria and has been communicated to employees. If employees are required to render future service in order to receive these one-time termination benefits, the liability is recognized ratably over the future service period. Termination benefits other than one-time termination benefits are termination benefits for which the communication criterion is not met but that are committed to by management, or termination obligations that are not specifically determined in a new and single plan. These termination benefits are all legal, contractual and past practice termination obligations to be paid to employees in case of involuntary termination. These termination benefits are accrued for when commitment creates a present obligation to others for the benefits expected to be paid, when it is probable that employees will be entitled to the benefits and the amount can be reasonably estimated.

In case of special termination benefits related to voluntary redundancy programs, the Company recognizes a provision for voluntary termination benefits at the date on which the employee irrevocably accepts the offer and the amount can be reasonably estimated.

(c) Profit-sharing and bonus plans

The Company recognizes a liability and an expense for bonuses and profit-sharing plans when a contractual obligation exists or when there is a past practice that has created a present obligation.

(d) Other long-term employee benefits

The Company provides long-term employee benefits such as seniority awards in certain countries. The entitlement to these benefits is usually conditional on the employee completing a minimum service period. The expected costs of these benefits are accrued over the period of employment. Actuarial gains and losses arising from changes in actuarial assumptions are charged or credited to earnings in the period of the revised estimate. These obligations are valued annually with the assistance of independent qualified actuaries.

(e) Share-based compensation

The Company accounts for stock-based compensation for all stock-based awards granted to senior executives and selected employees, including awards that vest upon the satisfaction of a service condition and awards that vest upon the satisfaction of both a service condition and a performance condition. Both equity awards vest over

F-15

a three-year service period while performance-based awards also require the Company’s attainment of certain performance conditions. The Company measures the cost of the awards based on the related grant-date fair value, reflecting the market price of the underlying shares at the date of the grant, reduced by the present value of the dividends expected to be paid during the requisite service period. That cost is recognized ratably over the period during which an employee is required to provide service in exchange for the award. The compensation cost is recorded through earnings with the corresponding amount reported in equity, under “Additional paid-in capital” of the consolidated statements of equity. The compensation cost is calculated based on the number of awards expected to vest, net of an estimated number of awards to be forfeited due to the employees failing to satisfy the service condition or one or more performance conditions. By the end of the vesting period, compensation is recognized only for the awards that ultimately vest.

Liabilities for the Company’s portion of payroll taxes are recognized at vesting, which is the event triggering the payment of the social contributions in most of the Company’s local tax jurisdictions. Employee-related social charges are measured based on the intrinsic value of the share and recorded at vesting date.

2.15     Share capital

Ordinary shares are classified as “Common stock” within equity on the consolidated balance sheets. Incremental costs directly attributable to the issuance of new shares are shown in equity as a deduction, net of tax, from the proceeds received.

Where the Company purchases its own equity share capital (treasury stock), the consideration paid, including any directly attributable incremental costs (net of income taxes), is deducted from parent company stockholders’ equity until the shares are cancelled, reissued, or disposed of.

2.16     Comprehensive income (loss)

Comprehensive income (loss) is defined as the change in equity of a business during a period except those changes resulting from investment by and distributions to stockholders. In the consolidated financial statements, “Other comprehensive income (loss)” and “Accumulated other comprehensive income” primarily consists of foreign currency translation adjustments, unrealized gains (losses) on debt securities classified as available-for-sale, unrealized gains (losses) on derivatives designated as cash flow hedge and the accounting for defined benefit plans, net of tax.

2.17     Revenue recognition

Arrangements with customers are considered contracts if all the following criteria are met: (a) parties have approved the contract and are committed to perform their respective obligations; (b) each party’s rights regarding the goods or services to be transferred can be identified; (c) payment terms for the goods or services to be transferred can be identified; (d) the contract has commercial substance and (e) collectability of substantially all of the consideration is probable. The Company recognizes revenue from products sold to a customer, including distributors, when it satisfies a performance obligation by transferring control over a product to the customer. The Company may also enter into several multi-annual capacity reservation and volume commitment arrangements with certain customers. These agreements constitute a binding commitment for the customers to purchase and for the Company to supply allocated commitment volumes in exchange for additional consideration. The consideration related to commitment fees is reported as revenues from sale of products as it is usually based on delivered quantities.

In certain circumstances, the Company may enter into agreements that concern principally revenues from services, where the performance obligation is satisfied over time. The objective when allocating the transaction price is to allocate the transaction price to each performance obligation (or distinct good or service) in an amount that depicts the amount of consideration to which the Company expects to be entitled in exchange for transferring the promised goods or services to the customer. The payment terms typically range between 30 to 90 days. Certain customers require the Company to hold inventory as consignment in their hubs and only purchase inventory when they require it. Revenue for sales of such inventory is recognized when, at the customer’s option, the products are withdrawn from the consignment and the Company satisfies a performance obligation by transferring control over a product to the customer.

F-16

Consistent with standard business practice in the semiconductor industry, price protection is granted to distribution customers on their existing inventory of the Company’s products to compensate them for changes in market prices. The Company accrues a provision for price protection based on a rolling historical price trend computed monthly as a percentage of gross distributor sales. This historical price trend represents differences in recent months between the invoiced price and the final price to the distributor, adjusted to accommodate a significant change in the selling price. The short outstanding inventory time, visibility into the inventory product pricing and long distributor pricing history have enabled the Company to reliably estimate price protection provisions at period-end. The Company records the accrued amounts as a deduction of “Net sales” in the consolidated statements of income at the time of the sale.

The Company’s customers occasionally return the Company’s products for technical reasons. The Company’s standard terms and conditions of sale provide that if the Company determines that products do not conform, the Company will repair or replace the non-conforming products, or issue a credit note or rebate of the purchase price. Quality returns are identified shortly after sale in customer quality control testing. The Company records the accrued amounts as a deduction of “Net sales” in the consolidated statements of income, using contractual and historical information.

The Company records a provision for warranty costs as a charge against “Cost of sales” in the consolidated statements of income, based on historical trends of warranty costs incurred as a percentage of sales, which management has determined to be a reasonable estimate of the probable losses to be incurred for warranty claims in a period. Any potential warranty claims are subject to the Company’s determination that the Company is at fault for damages, and such claims must usually be submitted within a short period of time following the date of sale. This warranty is given in lieu of all other warranties, conditions or terms expressed or implied by statute or common law. The Company’s contractual terms and conditions typically limit its liability to the sales value of the products which gave rise to the claims.

The Company’s insurance policy relating to product liability covers third-party physical damages and bodily injury, indirect financial damages as well as immaterial non-consequential damages caused by defective products.

In addition to product sales, the Company enters into arrangements with customers consisting in transferring licenses or related to license services. The revenue generated from these arrangements are reported on the line “Other revenues” of the consolidated statements of income.

2.18     Public funding

The Company receives funding from several governmental agencies and income is recognized when all contractual conditions for receipt of these funds are fulfilled and eligible expenditures incurred. Such funding is generally provided to encourage research, development and other innovation activities, industrialization deployment and local economic development. The conditions to receive government funding may include eligibility restrictions, approval by the local governmental authorities, annual budget appropriations, compliance with regulations, as well as specifications regarding objectives and results. Certain specific contracts include obligations to maintain a minimum level of employment and investment during a certain period. There could be penalties if these objectives are not fulfilled. Other contracts contain penalties for breach of contract, which may result in repayment obligations. Funding related to these contracts is recorded when the conditions required by the contracts are met. The Company’s funding programs are classified under two general categories: funding for research, development and other innovative activities, and capital investments.

Funding for research, development and innovative activities is the most common form of funding that the Company receives. This public funding is recorded as “Other income and expenses, net” in the consolidated statements of income. The funding is recognized ratably as the related costs are incurred once the agreement with the respective governmental agency has been signed and all applicable conditions are met. Other government assistance, such as funding received for industrialization deployment and local economic development in certain regions, are reported as a deduction of cost of sales or other operating expenses according to the nature of the underlying costs eligible to the grants.

French research tax credits (“Crédit Impôt Recherche”) and Italian research tax credits (“Credito d’Imposta Ricerca & Sviluppo”) are deemed to be grants in substance. The French research tax credits are to be paid in cash by the taxing authorities within three years in case they are not deducted from income tax payable during

F-17

this period of time. The Italian tax credits are compensated against payroll-related social charges. French and Italian tax credits are reported as a reduction of “Research and development expenses” in the consolidated statements of income.

Capital investment funding is recorded as a reduction of “Property, plant and equipment, net” on the consolidated balance sheets when the Company has incurred the eligible capital expenditures and when all conditions for eligibility have been fulfilled. Advances from capital grants received on capital investments that have not been incurred yet are reported as in the line "Other long-term liabilities" on the consolidated balance sheets. Capital investment funding is recognized in the Company’s consolidated statements of income by offsetting the depreciation charges of the funded assets during their useful lives. The Company also receives funding, which can be recovered through the reduction of various governmental liabilities, including income tax, value-added tax and employee-related social charges.

Funding receivables are reported as non-current assets unless cash settlement features of the receivables evidence that collection is expected within one year. Long-term receivables that do not present any tax attribute or legal restriction are reflected in the consolidated balance sheets at their net present value when the discounting effect is deemed to be significant.

2.19     Research and development

Research and development expenses include costs incurred by the Company, the Company’s share of costs incurred by other research and development interest groups, and costs associated with co-development contracts. Research and development expenses do not include marketing design center costs, which are accounted for as “Selling, general and administrative expenses” in the consolidated statements of income and process engineering, pre-production or process transfer costs which are recorded as “Cost of sales” in the consolidated statements of income. Research and development costs are expensed as incurred. The amortization expense recognized on technologies and licenses purchased by the Company from third parties to facilitate the Company’s research and development activities is reported as “Research and development expenses” in the consolidated statements of income.

2.20     Advertising costs

Advertising costs are expensed as incurred and are recorded as “Selling, general and administrative expenses” in the consolidated statements of income. Advertising expenses for 2023, 2022 and 2021 were $23 million, $18 million and $12 million, respectively.

2.21     Start-up and phase-out costs

Start-up costs represent costs incurred in the ramp-up phase of the Company's newly integrated manufacturing facilities. The costs of phase-outs are associated with the latest stages of facilities closure when the relevant production volumes become immaterial. Start-up costs and phase-out costs are included in the line “Other income and expenses, net” of the consolidated statements of income.

2.22     Investments in equity securities

Investments in equity securities that have readily determinable fair values and for which the Company does not have the ability to exercise significant influence are classified as equity securities measured at fair value through earnings. Changes in the fair value of these securities are reported in the consolidated statements of income within “Other income and expenses, net” when these instruments are held within the Company’s operating activities. Gains and losses arising from changes in the fair value of securities not related to operating activities are presented in the consolidated statements of income as non-operating elements within “Gain (loss) on financial instruments, net” in the period in which they arise. The fair values of quoted equity securities are based on current market prices. If the market for a financial asset is not active or if no observable market price is obtainable, the Company measures fair value by using assumptions and estimates. In measuring fair value, the Company makes maximum use of market inputs and minimizes the use of unobservable inputs.

F-18

For investments in equity securities without readily determinable fair values and for which the Company does not have the ability to exercise significant influence, the Company has elected to apply the cost method as a measurement alternative. Under the cost method of accounting, investments are carried at historical cost, less impairment. An impairment loss is recorded when there are identified events or changes in circumstances that may have a significant adverse effect on the value of the investment. Loss is immediately recorded in the consolidated statements of income on the line “Gain (loss) on financial instruments, net” and is based on the Company’s assessment of any significant and sustained reductions in the investment’s value. Gains and losses on investments sold are determined on the specific identification method and are recorded as non-operating element in the line “Gain (loss) on financial instruments, net” of the consolidated statements of income when the transaction is not related to operating activities.

The Company did not hold any material equity securities as of December 31, 2023 and December 31, 2022.

2.23     Investments in debt securities

Debt securities are included in current assets when they represent investments of funds available for current operations.

Changes in fair value of debt securities classified as available-for-sale are recognized as a component of “Other comprehensive income (loss)” in the consolidated statements of comprehensive income. The Company assesses at each balance sheet date whether there is objective evidence that a debt security or group of debt securities is impaired. An unrealized impairment loss exists when the fair value of the instrument declines below its amortized cost basis. An impairment loss is recognized in earnings, through a direct reduction of the value of the asset, when the Company intends to sell the debt security or when it is more likely than not that the Company will be required to sell the instrument before recovery of the amortized cost basis. Moreover, an impairment loss is recognized in earnings through a credit loss allowance for any portion of the unrealized impairment loss resulting from a credit loss. Impairment losses recognized in the consolidated statements of income are not reversed through earnings.

The fair values of quoted debt securities are based on current market prices. If the market for a financial asset is not active and if no observable market price is obtainable, the Company measures fair value by using assumptions and estimates. In measuring fair value, the Company makes maximum use of market inputs and minimizes the use of unobservable inputs.

The Company did not hold any debt securities classified as held-to-maturity or for which the Company would have elected to apply the fair value option.

2.24     Derivative financial instruments and hedging activities

Derivative financial instruments are initially recognized on the date a derivative contract is entered into and are subsequently measured at fair value. The method of recognizing the gain or loss resulting from the derivative instrument depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the hedge transaction. The Company has designated certain derivatives as hedges of a particular risk associated with a highly probable forecasted transaction (cash flow hedge).

The Company documents, at inception of the transaction, the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedging transactions. The Company also documents its assessment, both at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items. Derivative instruments that are not designated as hedges are measured at fair value through earnings.

Cash Flow Hedge

As part of its ongoing operating, investing and financing activities, the Company enters into certain derivative transactions that may be designated and may qualify as hedging instruments. To reduce its exposure to U.S. dollar exchange rate fluctuations, the Company hedges certain Euro-denominated forecasted transactions that cover at reporting date a large part of its research and development, and selling, general and administrative expenses as well as a portion of its front-end manufacturing costs of semi-finished goods within cost of sales

F-19

through the use of currency forward contracts and currency options, including collars. The Company also hedges through the use of currency forward contracts certain Singapore dollar-denominated manufacturing forecasted transactions.

The derivative instruments are designated and qualify for cash flow hedge at inception of the contract and on an ongoing basis over the duration of the hedge relationship. They are reflected at their fair value as “Other current assets” or “Other payables and accrued liabilities” in the consolidated balance sheets when settlement is expected to occur within twelve months after the reporting date. They are reported as "Other non-current assets" or "Other long-term liabilities" in the consolidated balance sheets when settlement is expected beyond twelve months. The criteria for designating a derivative as a hedge include the instrument’s effectiveness in risk reduction and matching of the derivative instrument to its underlying transactions with the critical terms of the hedging instrument matching the terms of the hedged forecasted transaction. This enables the Company to conclude that changes in cash flows attributable to the risk being hedged are expected to be substantially offset by the hedging instruments.

For derivative instruments designated as cash flow hedge, the change in fair value for the effective portion of the hedge is reported as a component of “Other comprehensive income (loss)” in the consolidated statements of comprehensive income and is reclassified into earnings in the same period in which the hedged transaction affects earnings, and within the same consolidated statements of income line as the hedged transaction. For these derivatives, ineffectiveness appears if the cumulative gain or loss on the derivative hedging instrument exceeds the cumulative change in the expected future cash flows on the hedged transaction. Effectiveness on transactions hedged through purchased options is measured on the full fair value of the option, including time value.

Derivative financial instruments not designated as a hedge

The Company conducts its business on a global basis in various major international currencies. As a result, the Company is exposed to adverse movements in foreign currency exchange rates. The Company enters into foreign currency forward contracts and currency options to reduce its exposure to changes in exchange rates and the associated risk arising from the denomination of certain assets and liabilities in foreign currencies at the Company's subsidiaries.

Financial instruments not designated as a hedge are classified as current assets when they are expected to be realized within twelve months of the balance sheet date. Marked-to-market gains or losses arising from changes in the fair value of these instruments are reported in the consolidated statements of income within “Other income and expenses, net” in the period in which they arise, since the transactions for these instruments occur within the Company’s operating activities.

2.25     Recent accounting pronouncements

(a)Accounting pronouncements effective in 2023

No new guidance was adopted in 2023 with a significant impact on the Company's financial statements, financial positions and operations.

(b)Accounting pronouncements expected to impact the Company’s operations that are not yet effective and have not been early adopted by the Company

In November 2023, the FASB issued new guidance related to segment reporting, which requires incremental disclosures about reportable segments, without changing though the definition of a segment or the guidance for determining reportable segments. The new guidance requires disclosures of significant segment expenses that are (i) regularly provided to (or easily computed from information regularly provided to) the chief operating decision maker ("CODM"); (ii) included in the reported measure of segment profit or loss. The new guidance also requires that an entity discloses, on an annual and interim basis, an amount for "other segment items" by reportable segment, and a description of its composition. Moreover, annual disclosures about a reportable segment's profit or loss and assets become mandatory on interim periods. Finally, the title and position of the CODM, together with an explanation of how the CODM uses the reported measures of segment profit or loss in assessing segment performance and deciding how to allocate resources, are also required. The guidance is effective for the Company's 2024 annual reporting and 2025 interim periods. The guidance will be applied retrospectively, with early adoption permitted. The Company will adopt the new guidance when effective and is currently assessing the impact the new guidance will have on its segment reporting.

F-20

In December 2023, the FASB issued new guidance related to income taxes, which requires additional disclosures, primarily around disaggregation of income tax paid and specific categories in the income tax rate reconciliation. The guidance is effective for the year ended December 31, 2025, with early adoption permitted. The guidance will be applied prospectively. Retrospective application is permitted. The Company is currently assessing the impact the new guidance will have on its annual income tax disclosures.

3.    SHORT-TERM DEPOSITS AND MARKETABLE SECURITIES

To optimize the return yield on its short-term investments, the Company invested $1,226 million of available cash in short-term deposits as of December 31, 2023, compared to $581 million as of December 31, 2022.

The Company also invested available liquidity in marketable securities. Changes in the fair value of marketable securities are detailed in the tables below:

	December 31, 2022	Purchase	Accretion	Proceeds at maturity	Change in fair value included in OCI*	December 31, 2023
U.S. Treasury debt securities	679	1,653	47	(750)	6	1,635
Total	679	1,653	47	(750)	6	1,635

*    Other Comprehensive Income

	December 31, 2021	Purchase	Accretion	Proceeds at maturity	Change in fair value included in OCI*	December 31, 2022
U.S. Treasury debt securities	—	687	8	—	(16)	679
Total	—	687	8	—	(16)	679

*    Other Comprehensive Income

In 2023, the Company invested $1,653 million available cash in U.S. Treasury bonds. The debt securities have an average rating of Aaa/AA+/AA+ from Moody’s, S&P and Fitch, respectively, with a weighted average maturity of 1.6 years. The debt securities are reported as current assets on the line “Marketable securities” on the consolidated balance sheet, since they represent investments of funds available for current operations. The Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of the amortized cost basis. The bonds are classified as available-for-sale financial assets and recorded at fair value as of December 31, 2023. The fair value measurement corresponds to a Level 1 fair value hierarchy measurement. The aggregate amortized cost basis of these securities totaled $1,645 million as of December 31, 2023.

Marketable securities totaling $750 million at principal amount were transferred to financial institutions as part of short-term securities lending transactions, in compliance with corporate policies. The Company, acting as the securities lender, does not hold any collateral in this unsecured securities lending transaction. The Company retains effective control on the transferred securities.

As of December 31, 2022, the Company held $679 million in marketable securities classified as available-for-sale debt securities. 

F-21

The below table details debt securities that were in an unrealized loss position as of December 31, 2023:

	December 31, 2023
	Less than 12 months		More than 12 months		Total
Description	Fair Value	Unrealized Losses	Fair Value	Unrealized Losses	Fair Value	Unrealized Losses
U.S. Treasury Bonds	429	(12)	157	(1)	586	(13)
Total	429	(12)	157	(1)	586	(13)

Debt securities that were in an unrealized gain position as of December 31, 2023, were reported at a fair value of $1,049 million with an unrealized gain of $4 million.

The Company did not report any debt securities that were in an unrealized loss position for more than one year as of December 31, 2022.

4.    TRADE ACCOUNTS RECEIVABLE, NET

Trade accounts receivable, net consist of the following:

	December 31,	December 31,
	2023	2022
Trade accounts receivable	1,750	1,991
Current expected credit losses allowance ("CECLA")	(19)	(21)
Total	1,731	1,970

The Company uses a lifetime expected losses allowance for all trade receivables based on failure rates, as applied to the gross amounts of trade accounts receivable. The allowance also includes reasonable assumptions about future credit trends. The historical loss rates are adjusted to reflect current and forward-looking information on macro-economic factors affecting the ability of the Company’s customers to settle the receivables. In addition to the factors already embedded in the failure rates, as applied on trade accounts receivable, the Company has identified cyclicality and uncertainties around continued growth for the semiconductor industry and its serviceable available market to be the most relevant factors. These macro-economic factors are weighted into different economic scenarios, in line with estimates and methodologies applied by other business entities, including financial institutions.

On that basis, the changes in reported CECLA for the year ended December 31, 2023 are presented below:

CECLA As of December 31, 2022	(21)
Current-period adjustment to CECLA	2
CECLA As of December 31, 2023	(19)

Adjustments to the expected credit losses allowance are reported in the line “Selling, general and administrative expenses” in the consolidated statements of income.

There were no significant write-offs in 2023, 2022 and 2021.

Advances and prepayments include prepaid amounts associated with multi-annual supply and service agreements.

Derivative instruments are further described in Note 26.

Other current assets include a $28 million contribution to be received in 2024 from a third party as part of a collaborative agreement associated with the ongoing capacity expansion project for the 300mm wafer fab in Crolles, France. Total contributions received from the third party as part of this collaborative agreement totaled $54 million, reported as "Proceeds from capital grants and other contributions" in the statement of cash flows for the year ended December 31, 2023.

The Company applies a current expected credit losses model on all financial assets measured at amortized cost, including deposits, loans and receivables. The major portion of other current assets to which this model applies corresponds to government receivables. Due to the existing history of zero-default on receivables originated by governments, the expected credit losses are assumed to be not significant as of December 31, 2023 and December 31, 2022. Other current assets presented in the table above within the lines “Loans and deposits” and “Other current assets” are composed of amounts not deemed at exposure of default. Consequently, no loss allowance was reported on those current assets as of December 31, 2023 and December 31, 2022.

12.    LONG-TERM INVESTMENTS AND VARIABLE INTEREST ENTITIES

	December 31, 2023	December 31, 2022
Long-term investments	22	11
Total	22	11

Long-term investments are equity securities with no readily determinable fair value for which the Company has elected to apply the cost method as a measurement alternative. Long-term investments include a $9 million interest in DNP Photomask Europe S.p.A (“DNP”). In 2023, the Company paid $10 million to acquire a minor

F-28

equity stake in a start up. The investment is related to the development of Silicon Photonics technology for the RF Communications business.

In 2023, the Company and Sanan Optoelectronics jointly created SANAN, STMicroelectronics Co., Ltd. for high-volume 200mm SiC device manufacturing activities in China. The purpose of the joint venture is to support the rising demand for the Company's SiC devices for car electrification and industrial power and energy applications in China. With the creation and future operations of SST JV, the Company seeks to create a fully integrated vertical value chain aiming at serving the Chinese electrification market. Sanan Optoelectronics will build a separate 200mm SiC substrate manufacturing facility to fulfill SST JV's needs. SST JV will produce SiC devices exclusively for the Company, using the Company's proprietary SiC manufacturing process technology and know how and serving as a dedicated foundry to support the Company's demand for Chinese customers.

The Company has identified SST JV as a VIE, primarily based on the disproportionality between its 49% equity interest rights and its economic interest and operating role in the joint venture. Indeed the significant activities of SST JV involve or are conducted on behalf of the Company as the sole customer of the joint venture. Moreover, through its key role in the successful process qualification and future manufacturing efficiency based on its SiC manufacturing process technology, the Company has the power to control the activities that most significantly impact SST JV's future economic performance. Additionally, based on the nature of the risks impacting SST JV's future economic performance, the Company will absorb the potential losses of SST JV or the right to receive benefits downstream the whole integrated SiC device value chain. Consequently, the Company has a controlling financing interest in SST JV and is the primary beneficiary of the VIE.

As the primary beneficiary of SST JV, the Company fully consolidates the VIE, with the recognition of 51% non-controlling interest. Non-controlling interest amounted to $52 million as of December 31, 2023, which corresponds to the capital contribution received from Sanan Optoelectronics upon creation and first consolidation of SST JV. No gain or loss was recognized on the initial consolidation of the VIE as no fair value measurement was required, the joint venture being a newly incorporated entity. Profit and loss reported by the VIE for the year ended December 31, 2023 was not material. The carrying amount of SST JV's assets and liabilities, together with their classification in the consolidated balance sheet as of December 31, 2023, are separately disclosed in Note 7, Note 10 and Note 17.

The joint venture agreement signed between Sanan Optoelectronics and the Company includes further capital subscriptions of both shareholders on a proportional equity interest basis. The total amount for the full build out of the joint venture will also be financed by local government support, as disclosed in Note 7, and loans to the joint venture.

13.    OTHER NON-CURRENT ASSETS

Other non-current assets are detailed below:

	December 31,	December 31,
	2023	2022

Derivative instruments	2	13
Other non-current assets	58	56
Total	808	661

F-29

Public funding receivables, including French research tax credit receivable, are described in Note 7.

Prepayments and deposits to third parties include receivables related to long-term supply agreements involving purchase of raw materials, capacity commitments, cloud-hosting arrangements, and other services.

In 2023 and 2022, the Company entered into factoring transactions to accelerate the realization in cash of certain long-term receivables. The Company sold without recourse $118 million and $110 million of these receivables in the years ended December 31, 2023 and 2022 respectively, with a financial cost of $5 million and $1 million respectively.

The major portion of other non-current assets to which the expected credit loss model applies are long-term State receivables. Due to the existing history of zero-default on receivables originated by governments, the expected credit losses are assumed to be negligible as of December 31, 2023 and December 31, 2022. Other non-current assets presented in the table above on the line “Other non-current assets” are composed of individually not significant amounts not deemed to have exposure of default. Consequently, no significant expected credit loss allowance was reported on other non-current assets at reporting date.

14.    OTHER PAYABLES AND ACCRUED LIABILITIES

Other payables and accrued liabilities are detailed below:

	December 31, 2023	December 31, 2022

Advances from customers are primarily related to multi-annual capacity reservation and volume commitment agreements signed in 2023 and 2022 with certain customers. Some of these arrangements include take-or-pay clauses, according to which the Company is entitled to receive the full amount of the contractual committed fees in case of non-compliant orders from those customers. Certain agreements include penalties in case the Company is not able to fulfill its contractual obligations. No significant provision for those penalties was reported on the consolidated balance sheets as of December 31, 2023 and December 31, 2022.

Liabilities related to public funding are described in Note 7.

3.78% due 2042, fixed interest rate	25	19
1.75% due 2042, fixed interest rate	2	—
Other funding program loans:
0.29% (weighted average), due 2024-2028, fixed interest rate	5	4
Total long-term debt	2,927	2,717
Less current portion	(217)	(175)
Total long-term debt, less current portion	2,710	2,542

Long-term debt is denominated in the following currencies:

	December 31, 2023	December 31, 2022
U.S. dollar	1,496	1,495
Euro	1,431	1,222
Total	2,927	2,717

On August 4, 2020, the Company issued a $1.5 billion principal amount of dual tranche senior unsecured convertible bonds (Tranche A and Tranche B for $750 million each tranche), due 2025 and 2027, respectively. Tranche A bonds were issued at 105.8% as zero-coupon bonds while Tranche B bonds were issued at 104.5% as zero-coupon bonds. The conversion price at issuance was $43.62 for Tranche A equivalent to a 47.5% conversion premium and $45.10 for Tranche B, equivalent to a 52.5% conversion premium. These conversion features correspond to an equivalent of 4,585 shares per each Tranche A bond $200,000 par value and an equivalent of 4,435 shares per each Tranche B bond $200,000 par value. The bonds are convertible by the bondholders or are callable by the issuer upon certain conditions, on a net-share settlement basis, except if the

F-31

issuer elects a full-cash or full-share conversion as an alternative settlement. The net proceeds from the bond offering were $1,567 million, after deducting issuance costs paid by the Company.

As per contractual terms, the bondholders have full conversion rights on Tranche A bonds, starting August 2023. In terms of Tranche B, up until August 2024, the bonds can be converted by the bondholders with a contingent feature of 130% of the conversion price, measured at quarter-end for the following quarter. After that date, the bondholders will have full conversion rights.

As per contractual terms, starting August 2023, Tranche A bonds are callable by the Company with a 130% contingent feature, with the exercise of its call rights being preceded by the release, by the Company, of an Optional Redemption Notice. The same feature applies for Tranche B bonds but only after August 2024.

As of December 31, 2023, the Company stock price exceeded the conversion price of the senior unsecured convertible bonds. However, the 130% stock price contingent feature was not met. Consequently, Tranche A bonds are not callable by the Company and bondholders cannot exercise their conversion rights on Tranche B bonds.

The convertible debt was reported as Long-term debt in the consolidated balance sheets as of December 31, 2023 and December 31, 2022, based on its original maturity, after having considered several factors, such as the uncertainty around the timing of the potential exercise of the conversion rights by bondholders and the call rights by the Company.

Aggregate future maturities of total long-term debt (including current portion) at principal amount are as follows:

	December 31,
	2023
2024	217
2025	962
2026	212
2027	947
2028	198
Thereafter	395
Total	2,931

The difference between the total aggregated future maturities in the preceding table and the total carrying amount of long-term debt is due to unamortized issuance costs on the dual tranche senior unsecured convertible bonds.

Credit facilities

The Company’s long-term debt contained standard conditions but does not impose minimum financial ratios. The Company had unutilized committed medium-term credit facilities with core relationship banks totalling $1,030 million as of December 31, 2023.

The EIB Loans are comprised of three long-term amortizing credit facilities as part of R&D funding programs. The first one, signed in August 2017, is a €500 million loan in relation to R&D and capital expenditures in the European Union for the years 2017 and 2018. The entire amount was fully drawn in Euros corresponding to $303 million outstanding as of December 31, 2023. The second one, signed in 2020, is a €500 million credit facility agreement with EIB to support R&D and capital expenditure programs in Italy and France. The amount was fully drawn in Euros representing $442 million outstanding as of December 31, 2023. In 2022, the Company signed a third long-term amortizing credit facility with EIB of €600 million, out of which, €300 million was withdrawn representing $332 million outstanding as of December 31, 2023. In January 2024, an amount of $300 million was withdrawn under this credit facility.

The CDP loans are comprised of two long-term credit facilities. The first, signed in 2021, is a €150 million loan, fully drawn in Euros, of which $97 million were outstanding as of December 31, 2023. The second one, signed in 2022, is a €200 million loan, fully drawn in Euros, of which $187 million was outstanding as of December 31, 2023.

16.    POST-EMPLOYMENT AND OTHER LONG-TERM EMPLOYEES BENEFITS

The Company and its subsidiaries have a number of defined benefit pension plans, mainly unfunded, and other long-term employees’ benefits covering employees in various countries. The defined benefit plans provide pension benefits based on years of service and employee compensation levels. The other long-term employees’ plans provide benefits due during the employees’ period of service after certain seniority levels. The Company uses December 31 as measurement date for its plans. Eligibility is generally determined in accordance with local statutory requirements. For Italian termination indemnity plan (“TFR”), generated before July 1, 2007, the Company measures the vested benefits to which Italian employees are entitled as if the amounts were immediately due as of December 31, 2023, in compliance with U.S. GAAP guidance on determining vested benefit obligations for defined benefit pension plans.

The actuarial losses incurred in 2023 were primarily due to a decrease in discount rates applied against future expected benefit payments and resulted in an increase of the benefit obligation mainly for the plans located in the United States, France and Switzerland. The actuarial gains incurred in 2022 were primarily due to an increase in discount rates applied against future expected benefit payments and resulted in a decrease of the benefit obligation mainly for the plans located in France, in the United States and Switzerland.

Actual return on plan assets reflect changes in market conditions during each reporting year.

The components of accumulated other comprehensive loss (income) before tax effects were as follows:

Pension benefits components other than service cost, recognized outside of operating income in “Other components of pension benefit costs” in the Company’s consolidated statements of income, were $19 million, $11 million and $10 million in the years ended December 31, 2023, 2022 and 2021, respectively.

The weighted average assumptions used to determine the benefit obligation and the periodic benefit costs for pension plans and other long-term benefits were as follows:

	2023		2022		2021
Benefit obligation
Discount rate	3.73	%	4.18	%	1.84	%
Salary increase rate	2.17	%	2.31	%	2.27	%
Net periodic benefit cost
Discount rate	4.18	%	1.84	%	1.45	%
Salary increase rate	2.31	%	2.27	%	2.43	%
Expected long-term rates of return on plan assets	2.66	%	3.19	%	3.44	%

The discount rate was determined by reference to market yields on high quality long-term corporate bonds applicable to the respective country of each plan, with terms consistent with the terms of the benefit obligations. In developing the expected long-term rate of return on assets, the Company modelled the expected long-term rates of return for broad categories of investments held by the plan against a number of various potential economic scenarios.

The Company’s pension plan asset allocation as of December 31, 2023 and December 31, 2022 is as follows:

	Percentage of Plan Assets at December
Asset Category	2023		2022
Cash and cash equivalents	1	%	1	%
Equity securities	13	%	17	%
Government debt securities	11	%	10	%
Corporate debt securities	19	%	21	%
Investments in funds(a)	15	%	16	%
Real estate	1	%	1	%
Other (mainly insurance assets – contracts and    reserves)	40	%	34	%
Total	100	%	100	%

(a)     As of December 31, 2023, investments in funds were composed of commingled and multi-strategy funds invested in diversified portfolios of fixed income (68%) - mainly corporate bonds, equities (24%), time deposits and money market (5%) and other instruments (3%). As of December 31, 2022, investments in funds were composed of commingled and multi-strategy funds invested in diversified portfolios of fixed income (79%) - mainly corporate bonds, time deposits and money market (11%) and other instruments (10%).

As of December 31, 2023, the Company’s plan asset allocation was in line with the targets set for each plan.

The majority of insurance contract plan assets relate to pension plans for the Company's employees in Switzerland. Those plans are provided by collective pension foundations and contributions are invested in fully insured assets that provide a guaranteed contractual return. As such, the fair value of such assets equals to the employees' accrued savings and calculated using total employer and employee contributions plus any accumulated interest credited, which is substantially equivalent to the related cash surrender value. The approach is consistent with prior years.

For plan assets measured at fair value using significant unobservable inputs (Level 3), the reconciliation between January 1, 2023 and December 31, 2023 is presented as follows:

	Fair Value Measurements using Significant Unobservable Inputs (Level 3)

The Company’s investment strategy for its pension plans is to optimize the long-term investment return on plan assets in relation to the liability structure to maintain an acceptable level of risk while minimizing the cost of providing pension benefits and maintaining adequate funding levels in accordance with applicable rules in each jurisdiction. The Company’s practice is to periodically conduct a review of its asset allocation strategy, in such a way that the asset allocation is in line with the targeted asset allocation within reasonable boundaries. The

F-37

Company’s asset portfolios are managed in such a way as to achieve appropriate diversification in line with the asset allocation strategy. The Company does not manage any assets internally.

After considering the funded status of the Company’s defined benefit plans, movements in the discount rate, investment performance and related tax consequences, the Company may choose to make contributions to its pension plans in any given year in excess of required amounts. The Company’s contributions to plan assets were $26 million in 2023 and $25 million in 2022 and the Company expects to contribute $27 million to plan assets in 2024.

The Company’s estimated future benefit payments as of December 31, 2023 are as follows:

Years	Pension Benefits	Other Long-term Benefits
2024	59	7
2025	63	8
2026	86	8
2027	54	9
2028	60	8
From 2029 to 2033	375	44

The Company has certain defined contribution plans, which accrue benefits for employees on a pro-rata basis during their employment period based on their individual salaries. The Company’s accrued benefits related to defined contribution pension plans for $27 million as of December 31, 2023 and $24 million as of December 31, 2022. The annual cost of these plans amounted to approximately $114 million in 2023, $100 million in 2022 and $101 million in 2021.

The newly incorporated entity is a party to a regional public funding program, primarily consisting in capital grants received on eligible capital expenditures (infrastructures and equipment). As of December 31, 2023, the Company received $152 million of advances on these capital grants while the capital expenditures had not been

F-38

incurred yet. Consequently, these advances were reported as long-term liabilities in the consolidated balance sheet as of December 31, 2023. Public funding is further described in Note 7.

Advances from customers are described in Note 14 and Note 19.

Derivative instruments are described in Note 26.

18.    SHAREHOLDERS’ EQUITY

18.1     Outstanding shares

The authorized share capital of the Company is Euro 1,810 million, consisting of 1,200,000,000 common shares and 540,000,000 preference shares, each with a nominal value of €1.04. As of December 31, 2023, the number of shares of common stock issued was 911,281,920 shares (911,281,920 as of December 31, 2022).

As of December 31, 2023, the number of shares of common stock outstanding was 902,771,081, 903,865,763 as of December 31, 2022 and 906,518,057 as of December 31, 2021.

18.2     Preference shares

The 540,000,000 preference shares, when issued, will entitle a holder to full voting rights and to a preferential right to dividends and distributions upon liquidation.

The Company is a party to an option agreement regarding the preference shares with Stichting Continuïteit ST (the “Stichting”), entered into on January 22, 2007, with a duration of ten years, an agreement which was extended for another ten years in October 2016. The Managing Board and Supervisory Board, along with the board of the Stichting, have declared that they are jointly of the opinion that the Stichting is independent of the Company. The option agreement provides for the issuance of up to a maximum 540,000,000 preference shares. Any such shares would be issued to the Stichting upon its request and in its sole discretion and upon payment of at least 25% of the par value of the preference shares to be issued. The shares would be issuable in the event of actions which the board of the Stichting determines would be contrary to the Company’s interests, shareholders and other stakeholders and which, in the event of a creeping acquisition or offer for the Company’s common shares, are not supported by the Company’s Managing Board and Supervisory Board. The preference shares may remain outstanding for no longer than two years. The effect of the preference shares may be to deter potential acquirers from effecting an unsolicited acquisition resulting in a change of control as well as to create a level-playing field in the event actions which are considered to be hostile by the Company’s Managing Board and Supervisory Board, as described above, occur and which the board of the Stichting determines to be contrary to the Company’s interests, shareholders and other stakeholders.

There were no preference shares issued as of December 31, 2023 and December 31, 2022.

18.3     Treasury stock

As of December 31, 2023, the Company owned 8,510,839 shares classified as treasury stock in the consolidated statement of equity compared to 7,416,157 shares as of December 31, 2022 and 4,758,863 shares as of December 31, 2021.

The treasury shares have been originally designated for allocation under the Company’s share-based remuneration programs. As of December 31, 2023, 81,022,515 of these treasury shares were transferred to employees under the Company’s share-based remuneration programs, of which 6,502,300 during the year ended December 31, 2023, 6,587,002 shares during the year ended December 31, 2022 and 7,448,615 shares during the year ended December 31, 2021.

On July 1, 2021, the Company announced the launch of a share buy-back program of up to $1,040 million to be executed within a three-year period. During 2023, the Company purchased approximately 7.6 million shares of its outstanding common stock for $346 million as part of the program. The Company purchased approximately

9.2 million shares of its outstanding common stock for $346 million during 2022. The Company purchased approximately 3.9 million shares of its outstanding common stock for $172 million during 2021.

18.4     Unvested share awards for the Supervisory Board

On an annual basis and until the year 2012, the Compensation Committee (on behalf of the Supervisory Board and with its approval) used to grant stock-based awards (options to acquire common shares of the Company) to the members and professionals of the Supervisory Board (“The Supervisory Board Plan”). The awards were granted at the nominal value of the share of €1.04 (exercise price of the option). The options granted under the Supervisory Board Plan vested and became exercisable immediately, while the shares resulting from these awards vested and therefore became available for trade evenly over three years (one third every year), with no market, performance or service conditions.

At the Company’s AGM held on June 21, 2013, it was resolved to abolish and terminate the stock-based compensation for the Supervisory Board members and professionals.

The table below summarizes grants under the outstanding stock award plans, as authorized by the Compensation Committee:

Year of grant	Options granted	Options waived at grant
2011	172,500	(30,000)
2012	180,000	(22,500)
Since 2013	No options granted

A summary of the options’ activity by plan for the years ended December 31, 2023 and December 31, 2022 is presented below:

18.5     Unvested share awards for the employees

On an annual basis, the Compensation Committee (on behalf of the Supervisory Board and with its approval) grants stock-based awards to the senior executives and selected employees (the “Employee Plan”). The awards are granted for services rendered under the Employee Plan. There are two types of unvested shares: (1) shares granted to employees, which are subject only to service conditions and vest over the requisite service period, and (2) shares granted to senior executives, for which vesting is subject to performance conditions.

For plan 2020, the performance conditions consisted of two external targets (sales evolution and operating income compared to a basket of competitors) weighting for two thirds of the total number of awards granted, and of one internal target (return on net assets compared to the previous period), weighting for one third of the total number of awards granted. For plans 2021, 2022 and 2023, the performance conditions consist of two external targets (sales evolution and operating income compared to a basket of competitors) weighting for two thirds of the total number of awards granted, and of one internal target (Company’s sustainability and diversity performance), weighting for one third of the total number of awards granted. Sustainability and diversity performance include environment/climate, diversity and inclusions indicators, ESG investor index and carbon rating.

Stock awards are subject to three-year cliff-vesting for the Company's CEO, while they vest over a grading three-year service period for other employees (32% as of the first anniversary of the grant, 32% as of the second anniversary of the grant and 36% as of the third anniversary of the grant). Applicable only to the 2023 plan,

F-40

stock awards allocated to members of the Executive Committee are also subject to three-year cliff vesting. In addition, for the year 2020, a Special Bonus was granted to the Company’s CEO.

The table below summarizes grants outstanding during the year 2023, as authorized by the Compensation Committee:

(*)    As of the date of issuance of these consolidated financial statements, a final decision by the Compensation Committee of the Supervisory Board on the achievement of the performance conditions had not been made yet.

A summary of the unvested share activity by plan for the year ended December 31, 2023 is presented below:

Unvested Shares	Unvested as at December 31, 2022	Granted	Forfeited / waived	Cancelled on failed vesting conditions	Vested	Unvested as at December 31, 2023
2020 CEO Special Bonus	5,334	—	—	—	(5,334)	—
2020 Employee Plan	2,780,796	—	(11,851)	—	(2,768,945)	—
2021 Employee Plan	3,699,514	—	(32,571)	—	(1,716,700)	1,950,243
2022 Employee Plan	6,496,525	—	(80,065)	—	(2,065,721)	4,350,739
2023 Employee Plan	—	5,449,135	(28,730)	—	—	5,420,405
Total	12,982,169	5,449,135	(153,217)	—	(6,556,700)	11,721,387

The grant date fair value of unvested shares granted to the CEO under the 2020 CEO Special Bonus Plan was $26.64, which was based on the market price of the shares at the date of the grant.  

The grant date weighted average fair value of unvested shares granted to employees under the 2020 Employee Plan was $30.17. On March 24, 2021, the Compensation Committee approved the statement that with respect to the shares subject to performance conditions, all three performance conditions were fully met. Consequently, the compensation expense recorded on the 2020 Employee Plan reflects the statement that – for the portion of shares subject to performance conditions – 100% of the awards granted has fully vested, as far as the service condition was met.

The grant date weighted average fair value of unvested shares granted to employees under the 2021 Employee Plan was $39.20. On March 23, 2022, the Compensation Committee approved the statement that with respect to the shares subject to performance conditions, two performance conditions were fully met. Consequently, the compensation expense recorded on the 2021 Employee Plan reflects the statement that – for the portion of shares subject to performance conditions – two thirds of the awards granted will fully vest, as far as the service condition is met.

The grant date weighted average fair value of unvested shares granted to employees under the 2022 Employee Plan was $35.92. On March 22, 2023, the Compensation Committee approved the statement that with respect to

F-41

the shares subject to performance conditions, all three performance conditions were fully met. Consequently, the compensation expense recorded on the 2022 Employee Plan reflects the statement that – for the portion of shares subject to performance conditions – 100% of the awards granted will fully vest, as far as the service condition is met.

The grant date weighted average fair value of unvested shares granted to employees under the 2023 Employee Plan was $50.96. Moreover, for the portion of the shares subject to performance conditions (2,589,952 shares) the Company estimated the number of awards expected to vest by assessing the probability of achieving the performance conditions. As of the date of issuance of these consolidated financial statements, a final determination by the Compensation Committee of the Supervisory Board of the achievement of the performance conditions had not been made yet. The Company estimated that 100% of the awards subject to performance conditions are expected to vest. Consequently, the compensation expense recorded for the 2023 Employee Plan reflects the expected vesting of 100% of the awards granted with performance conditions, subject to the service condition being met. The assumption of the expected number of awards to be vested upon achievement of the performance conditions is subject to changes based on the final measurement of the conditions, which is expected to occur in the first half of 2024.

The following table illustrates the classification of pre-payroll tax and social contribution stock-based compensation expense included in the consolidated statements of income for the years ended December 31, 2023, 2022 and 2021:

	December 31, 2023	December 31, 2022	December 31, 2021
Cost of sales	40	34	34
R&D	71	69	70
SG&A	125	112	117
Total pre-payroll tax and social contribution    compensation	236	215	221

The grant date fair value of the shares that vested in 2023 was $226 million compared to $189 million in 2022 and $181 million in 2021.

Stock-based compensation, excluding payroll tax and social contribution, capitalized as part of inventory was $13 million as of December 31, 2023, compared to $11 million as of December 31, 2022 and $9 million as of December 31, 2021. As of December 31, 2023, there was $265 million of total unrecognized compensation cost related to the grant of unvested shares, which is expected to be recognized over a weighted average period of approximately 10 months.

The total deferred income tax benefit recognized in the consolidated statements of income related to unvested share-based compensation expense amounted to $17 million, $15 million and $14 million for the years ended December 31, 2023, 2022 and 2021, respectively.

18.7     Dividends

The Company is governed under the laws of the Netherlands. The Articles of Association provide that the net result for the year, after deduction of (i) any amount to set up and maintain reserves required by Dutch Law and the Articles of Association, (ii) if any of our preference shares are issued and outstanding, the dividend to be paid to the holders of preference shares and (iii) the aforementioned allocation to the reserve fund, is subject to the disposition by the General Meeting of Shareholders ("AGM").

19.    REVENUES

19.1     Nature of goods and services

The Company designs, develops, manufactures and markets a broad range of products, including discrete and standard commodity components, application-specific integrated circuits (“ASICs”), full-custom devices and semi-custom devices and application specific standard products (“ASSPs”) for analog, digital and mixed-signal applications. In addition, the Company participates in the manufacturing value chain of smartcard products, which includes the production and sale of both silicon chips and smartcards.

The principal activities – separated by reportable segments – from which the Company generates its revenues are described in Note 20.

Other revenues consist of license revenue, service revenue related to transferring licenses, patent royalty income, sale of scrap materials and manufacturing by-products.

While the majority of the Company’s sales agreements contain standard terms and conditions, the Company may, from time to time, enter into agreements that contain multiple performance obligations or terms and conditions. Those agreements concern principally the revenues from services, where the performance obligation is satisfied over time. The objective when allocating the transaction price is to allocate the transaction price to each performance obligation (or distinct good or service) in an amount that depicts the amount of consideration to which the Company expects to be entitled in exchange for transferring the promised goods or services to the customer.

19.2     Revenue recognition and disaggregation

The Company recognizes revenue from products sold to a customer, including distributors, when it satisfies a performance obligation at a point in time by transferring control over a product to the customer. This usually occurs at the time of shipment. The performance obligations linked to the sale of goods contracts have the original expected length of less than one year. The transaction price is determined based on the contract terms, adjusted for price protection, if applicable. The revenues from services are usually linked to performance obligations transferred over time and are recognized in line with the contract terms.

In 2023 and 2022, the Company signed several multi-annual capacity reservation and volume commitment arrangements with certain customers. These agreements constitute a binding commitment for the customers to purchase and for the Company to supply allocated commitment volumes in exchange for additional consideration. The consideration related to commitment fees is reported as revenues from sale of products as it is usually based on delivered quantities. Advances from customers received as part of those agreements are described in Note 14 and Note 17.

The payment terms typically range between 30 to 90 days.

The Company’s consolidated net revenues disaggregated by reportable segment are presented in Note 20. The following tables present the Company’s consolidated net revenues disaggregated by geographical region of shipment, nature and market channel:

Distribution	5,818	5,364	4,275
Total net revenues	17,286	16,128	12,761

(1)Net revenues by geographical region of shipment are classified by location of customer invoiced or reclassified by shipment destination in line with customer demand. For example, products ordered by U.S.-based companies to be invoiced to Asia Pacific affiliates are classified as Asia Pacific revenues. Furthermore, the Company, among the different periods, may be affected by shifts in shipments from one location to another, as requested by customers.

(2)Original Equipment Manufacturers (“OEM”) are the end-customers to which the Company provides direct marketing application engineering support, while Distribution refers to the distributors and representatives that the Company engages to distribute its products around the world.

The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which the Company recognizes revenue at the amount to which the Company has the right to invoice for services performed.

In 2023, 2022 and 2021, the Company’s largest customer, Apple, represented 12.3%, 16.8% and 20.5% of consolidated net revenues, respectively, reported in the ADG, AMS and MDG segments.

20.    SEGMENT INFORMATION

The Company designs, develops, manufactures and markets a broad range of products, including discrete and standard commodity components, ASICs, full custom devices and semi-custom devices and ASSPs for analog, digital, and mixed-signal applications. In addition, the Company further participates in the manufacturing value chain of smartcard products, which includes the production and sale of both silicon chips and smartcards.

As of December 31, 2023, the Company’s reportable segments were as follows:

•Automotive and Discrete Group (ADG), comprised of dedicated automotive integrated circuits (“ICs”), and discrete and power transistor products.

•Analog, MEMS and Sensors Group (AMS), comprised of analog, smart power, MEMS sensors and actuators, and optical sensing solutions.

•Microcontrollers and Digital ICs Group (MDG), comprised of general-purpose microcontrollers and microprocessors, connected security products (e.g. embedded secured elements and NFC readers), memories (e.g. serial and page EEPROM) and RF and Communications products.

Net revenues of “Others” include revenues from sales assembly services and other revenues. For the computation of the segments’ internal financial measurements, the Company uses certain internal rules of allocation for the costs not directly chargeable to the segments, including cost of sales, SG&A expenses and a part of R&D expenses. In compliance with the Company’s internal policies, certain costs are not allocated to the segments, but reported in “Others”. Those comprise unused capacity charges, including reduced manufacturing activity due to COVID-19 and incidents leading to power outage, impairment, restructuring charges and other related closure costs, management reorganization expenses, start-up and phase-out costs, and other unallocated

F-46

income (expenses) such as: strategic or special R&D programs, certain corporate-level operating expenses, patent claims and litigations, and other costs that are not allocated to product groups, as well as operating earnings of other products. In addition, depreciation and amortization expense is part of the manufacturing costs allocated to the segments and is neither identified as part of the inventory variation nor as part of the unused capacity charges; therefore, it cannot be isolated in cost of sales. Finally, public grants are allocated to the Company’s segments proportionally to the incurred expenses on the sponsored projects.

Wafer costs are allocated to the segments based on actual cost. From time to time, with respect to specific technologies, wafer costs are allocated to segments based on market price.

The following tables present the Company’s consolidated net revenues and consolidated operating income by reportable segment.

The following is a summary of operations by entities located within the indicated geographic areas for 2023, 2022 and 2021. Net revenues represent sales to third parties from the country in which each subsidiary is domiciled. The Company is incorporated under Dutch law with head offices located in the Netherlands while the Company’s operational office and headquarters are located in Switzerland. Long-lived assets consist of property, plant and equipment, net. A significant portion of property, plant and equipment expenditures is attributable to front-end and back-end facilities, located in the different countries in which the Company operates. As such, the Company mainly allocates capital spending resources according to geographic areas rather than along product segment areas.

Start-up costs represent costs incurred in the ramp-up phase of the Company’s newly integrated manufacturing facilities, primarily for the new 300mm fab in Agrate, Italy. Phase-out costs are costs incurred during the closing stage of a Company’s manufacturing facility.

Exchange gains and losses, net represent the portion of exchange rate changes on transactions denominated in currencies other than a subsidiary’s functional currency and the changes in fair value of derivative instruments which are not designated as hedges, as described in Note 26.

Patent costs mainly include legal and attorney fees and payment for claims, patent pre-litigation consultancy and legal fees. They are reported net of settlements, if any, which primarily include reimbursements of prior patent litigation costs.

COVID-19 incremental costs were mainly composed of incremental expenses primarily related to sanitary measures undertaken to protect employees. Starting January 1, 2023, the Company no longer reports Covid-19 related expenses as a component of the line “Other income and expenses, net” in the consolidated statement of income.

F-49

22.    INTEREST INCOME (EXPENSE), NET

Interest income (expense), net consisted of the following:

	Year ended December 31, 2023	Year ended December 31, 2022	Year ended December 31, 2021
Income	226	71	13
Expense	(55)	(13)	(42)
Total	171	58	(29)

Interest income is related to cash and cash equivalents, short-term deposits and marketable securities held by the Company.

Interest income, net recorded in 2023 was composed of $226 million of interest income, partially offset by interest expense on borrowings and banking fees of $55 million.

Interest expense included the financial cost of the convertible bonds issued by the Company in 2020. On January 1, 2022, the Company adopted the new U.S. GAAP reporting guidance on distinguishing liabilities from equity and EPS. The new guidance was adopted by applying the modified retrospective method, under which prior year periods are not restated. Interest expense recorded in 2021 included a charge of $34 million related to the outstanding senior unsecured convertible bonds, mainly resulting from the non-cash accretion expense, as recorded under the previous accounting guidance. With the adoption of the new guidance, the finance cost of the convertible debt instruments outstanding at the date of adoption is limited to the amortization expense of debt issuance costs. The amortization expense of debt issuance costs amounted to $1 million for the year ended December 31, 2023, $1 million for the year ended December 31, 2022 and $3 million for the year ended December 31, 2021.

No borrowing cost was capitalized in 2023, 2022 and 2021. Nominal interest income received in cash on U.S. Treasury Bonds classified as available-for-sale marketable securities amounted to $15 million for the year ended December 31, 2023, $1 million for the year ended December 31, 2022 and $1 million for the year ended December 31, 2021.

STMicroelectronics N.V. and its subsidiaries are individually liable for income taxes in their jurisdictions.

F-50

Income tax benefit (expense) is comprised of the following:

	Year ended December 31, 2023		Year ended December 31, 2022		Year ended December 31, 2021
The Netherlands taxes - current	—		—		—
Foreign taxes - current	(528)		(510)		(285)

The principal items comprising the differences in income taxes computed at the Netherlands statutory rate of 25.8% in 2023, 25.8% in 2022 and 25% in 2021, and the effective income tax rate are the following:

	Year ended December 31, 2023	Year ended December 31, 2022	Year ended December 31, 2021
Income tax benefit (expense) computed at    statutory rate	(1,229)	(1,158)	(584)

Change in valuation allowances	—	140	(2)
Effect of changes in tax laws and similar	149	6	6
Current year tax credits	29	30	39
Other tax and credits	34	(51)	(22)
Benefits from tax holidays	45	60	49
Net impact of changes to uncertain tax positions	(8)	(12)	(8)
Earnings of subsidiaries taxed at different rates	433	443	187
Income tax benefit (expense)	(541)	(520)	(331)

In 2022, the variation on the valuation allowance was related to the assessment of the recoverability of the deferred tax assets following the improved stability of profits of the Company in various jurisdictions.

The variation in the line "Effect of changes in tax laws and similar" in 2023 mainly relates to the recognition of a net deferred tax asset of $52 million related to a tax credit granted for technological activities, as well as the impact of the conclusion in 2023 of tax authority discussions resulting in the recognition of a net deferred tax asset of $81 million for intangibles recognized for tax purposes. These will be amortized over time and result in a future cash tax benefit.

The tax holidays represent a tax exemption period aimed to attract foreign technological investment in certain tax jurisdictions. The effect of the tax benefits, from tax holidays for countries which are profitable, on basic earnings per share was $0.05, $0.07 and $0.05 for the years ended December 31, 2023, 2022 and 2021, respectively. These agreements are present in various countries and include programs that reduce up to and including 100% of taxes in years affected by the agreements. The Company’s tax holidays expire at various dates through the year ending December 31, 2029. In certain countries, tax holidays can be renewed depending on the Company still meeting certain conditions at the date of expiration of the current tax holidays.

Component of the Net Deferred Tax Asset and Liability

Deferred tax assets and liabilities consisted of the following:

	December 31, 2023	December 31, 2022
Tax loss carryforwards, tax credits and other tax attributes	886	520
Less unrecognized tax benefits	(21)	(25)

Deferred tax assets, net	880	860
Accelerated fixed asset depreciation	(40)	(37)
Acquired intangible assets	(24)	(23)
Advances of government funding	(185)	(177)
Operating lease right-of-use assets	(62)	(50)
Other temporary differences	(31)	(31)
Deferred tax liabilities	(342)	(318)
Net deferred income tax asset	538	542

For a particular tax-paying component of the Company and within a particular tax jurisdiction, all deferred tax liabilities and assets are offset and presented as a single amount in the balance sheet. The Company does not offset deferred tax liabilities and assets attributable to different tax-paying components or to different tax jurisdictions. The above table presents the deferred tax assets and liabilities before offset.

The variations in the lines "Tax losses carried forward, tax credits and other tax attributes" and "Valuation allowances” mainly include the recognition of deferred tax assets for a tax credit related to technological activities and the impact of the conclusion of discussions with the tax authorities for intangibles recognized for tax purposes, totaling $479 million decreased by $126 million related to the utilization of the tax losses in several jurisdictions following management’s assessment of the likelihood of future realization of the gross DTA recognized in the period.

The “Tax credits granted on capital investments” is mainly related to a 2003 agreement granting the Company certain tax credits for capital investments purchased through the year ending December 31, 2006. Any unused tax credits granted under the agreement will be impacted yearly by a legal inflationary index (currently 3.64% per annum). The credits may be utilized depending on the Company meeting certain program criteria and have no expiration date. In addition to this agreement, starting from 2007 the Company continues to receive tax credits on the yearly capital investments, which may be used to offset that year’s tax liabilities and increases by the legal inflationary rate. However, pursuant to the inability to utilize these credits currently and in future years,

F-52

the Company did not recognize any deferred tax asset on such tax allowance. As a result, there is no financial impact to the net deferred tax assets of the Company.

Deferred tax asset expiration

As of December 31, 2023, the Company and its subsidiaries have gross deferred tax assets on tax loss carryforwards, tax credits and other tax attributes that expire starting from 2024.

	December 31,
Year	2023
2024	3
2025	2
2026	2
2027	4
2028	3
Thereafter	872
Total	886

The amount reported on the line “Thereafter” includes tax attributes that expire in 2029 for $276 million and tax credit which will expire in 2030 for $203 million. The majority of the remaining amount has no expiration date.

Deferred Tax expense recognized through Other Comprehensive Income

In 2023, the Company recognized a deferred tax expense of $4 million as a component of other comprehensive income (loss), compared to a deferred tax expense of $26 million in 2022. They were related primarily to the tax effects of the recognized unfunded status on defined benefits plan.

Deferred tax on undistributed Earnings from foreign subsidiaries

The cumulative amount of distributable earnings related to the Company’s investments in foreign subsidiaries and corporate joint ventures was $7,575 million and $7,140 million as of December 31, 2023 and December 31, 2022, respectively. Due to the Company’s legal and tax structure, with the parent company established in the Netherlands, there is no significant tax impact from the distribution of earnings for $6,965 million from investments in foreign subsidiaries and corporate joint ventures. This is because there is no tax impact on dividends paid up to a Dutch holding company by qualifying investments. The amount of distributable earnings becoming taxable upon repatriation amount to $607 million. An amount of $387 million is indefinitely reinvested by the foreign subsidiaries. As of December 31, 2023, a deferred tax liability is recognized for $22 million on the amount of earnings expected to be repatriated in a foreseeable future.

In addition, as of December 31, 2023, $21 million of unrecognized tax benefits were classified as a reduction of deferred tax assets (as of December 31, 2022, the amount was $25 million). It is reasonably possible that certain of the uncertain tax positions disclosed in the table above could increase or decrease within the next 12 months due to ongoing tax audits. The Company is not able to make an estimate of the range of the reasonably possible change impacting the annual effective tax rate.

Additionally, the Company elected to classify accrued interest and penalties related to uncertain tax positions as components of income tax expense in the consolidated statements of income. They were less than $1 million in 2023, less than $1 million in 2022 and $1 million in 2021. Accrued interest and penalties amounted to $6 million as of December 31, 2023 and $6 million as of December 31, 2022.

The tax years that remain open for review from the tax authorities in the Company’s major tax jurisdictions are from 1997 to 2023.

Pillar II income taxes

Pillar II legislation has been enacted in certain jurisdiction the Company operates (Netherlands, the majority of the European Countries and Switzerland). The legislation will be effective for the Company's financial year beginning January 1, 2024. The Company is in the scope and has performed a preliminary assessment of the potential exposure of the Pillar II incomes taxes.

The assessment of the potential exposure to Pillar II income taxes is based on the most recent tax filings, 2022 country-by-country reporting and financial statements for the constituent entities in the Company. Based on the assessment, the Pillar II effective tax rates in most of the jurisdictions are above 15%. However, there is a limited number of jurisdictions where the transitional safe harbour relief does not apply and the Pillar II effective tax rate is slightly below 15%. Therefore, the Company expects a limited tax exposure to Pillar II income taxes in those jurisdictions. Pillar II income taxes impact will depend on the level of 2024 operating results within those jurisdictions as well as potential enactment of the Pillar II legislation or change in tax laws in those jurisdictions.

24.    EARNINGS PER SHARE

For the years ended December 31, 2023, 2022 and 2021, earnings per share (“EPS”) was calculated as follows:

	Year ended December 31, 2023	Year ended December 31, 2022	Year ended December 31, 2021
Basic EPS
Net income attributable to parent company as reported	4,211	3,960	2,000
Weighted average number of shares outstanding	903,513,952	905,606,885	904,332,429

Diluted EPS	4.46	4.19	2.16

On January 1, 2022, the Company adopted the new guidance on distinguishing liabilities from equity and EPS by applying the modified retrospective method, under which prior year periods are not restated.

Under the previous guidance, the Company applied the treasury stock method to determine the dilutive effect of convertible bonds as past experience, existing stated policies, and the contractual terms of the bonds provided a reasonable basis to expect that the settlement would include cash, shares, or a mix of both.

With the adoption of the new guidance, the treasury stock method is no longer admitted and the application of the if-converted method is mandatory to determine the dilutive effect of convertible bonds. The senior unsecured convertible bonds issued on August 4, 2020 are consequently fully dilutive, with the total underlying shares presented in the line “Dilutive effect of convertible bonds” of the table above for the years ended December 31, 2023 and December 31, 2022.

25.    COMMITMENTS, CONTINGENCIES, CLAIMS AND LEGAL PROCEEDINGS

The Company's commitments relate to multi-annual agreements with suppliers when there is a fixed, non-cancelable commitment or when minimum payments are due on a committed delivery schedule. These commitments are primarily comprised of purchase commitments for outsourced foundry wafers ($1.1 billion) and firm contractual commitments related to power purchase and minimum energy efficiency, as part of the Company's actions to become carbon neutral by 2027 on scope 1 and 2 and partially scope 3 ($0.8 billion).

The Company is subject to possible loss contingencies arising in the ordinary course of business. These include but are not limited to: product liability claims and/or warranty cost on the products of the Company, contractual disputes, indemnification claims, claims for unauthorized use of third-party intellectual property, employee grievances, tax claims beyond assessed uncertain tax positions as well as claims for environmental damages. In determining loss contingencies, the Company considers the likelihood of impairing an asset or the incurrence of a liability at the date of the consolidated financial statements as well as the ability to reasonably estimate the amount of such loss. The Company records a provision for a loss contingency when information available before the consolidated financial statements are issued or are available to be issued indicates that it is probable that an asset has been impaired or a liability has been incurred at the date of the consolidated financial statements and when the amount of loss can be reasonably estimated. The Company regularly re-evaluates claims to determine whether provisions need to be readjusted based on the most current information available to the Company. Changes in these evaluations could result in an adverse material impact on the Company’s results of operations, cash flows or its financial position for the period in which they occur.

F-55

The Company has received and may in the future receive communications alleging possible infringements of third-party patents or other third-party intellectual property rights. Furthermore, the Company from time to time enters into discussions regarding a broad patent cross license arrangement with other industry participants. There is no assurance that such discussions may be brought to a successful conclusion and result in the intended agreement. The Company may become involved in costly litigation brought against the Company regarding patents, mask works, copyrights, trademarks or trade secrets. In the event that the outcome of any litigation would be unfavorable to the Company, the Company may be required to take a license to third-party patents and/or other intellectual property rights at economically unfavorable terms and conditions, and possibly pay damages for prior use and/or face an injunction, all of which individually or in the aggregate could have a material adverse effect on the Company’s results of operations, cash flows, financial position and/or ability to compete.

On December 4, 2023, a jury in the United States District Court for the Western District of Texas in Waco, Texas (USA) returned a verdict in a patent infringement lawsuit in favor of the plaintiff, Purdue University. The Court has not issued final judgment. If the Court issues a final judgment in the plaintiff’s favor, the Company will file post-trial motions and, if they are denied, the Company will file an appeal to the United States Court of Appeals for the Federal Circuit in Washington DC. The risk on this case is considered as possible and, based on the jury verdict, the possible loss is estimated at $32 million.

The Company has contractual commitments to various customers which could require the Company to incur costs to repair or replace defective products it supplies to such customer. The duration of these contractual commitments varies and, in certain cases, is indefinite. The Company is otherwise also involved in various lawsuits, claims, inquiries, inspections, investigations and/or proceedings incidental to its business and operations. Such matters, even if not meritorious, could result in the expenditure of significant financial or managerial resources. Any of the foregoing could have a material adverse effect on the Company’s results of operations, cash flows or its financial position.

The Company regularly evaluates claims and legal proceedings together with their related probable losses to determine whether they need to be adjusted based on the current information available to the Company. There can be no assurance that its recorded reserves will be sufficient to cover the extent of its potential liabilities. Legal costs associated with claims are expensed as incurred. In the event of litigation which is adversely determined with respect to the Company’s interests, or in the event the Company needs to change its evaluation of a potential third-party claim, based on new evidence or communications, a material adverse effect could impact its operations or financial condition at the time it were to materialize.

As of December 31, 2023 and 2022, respectively, provisions for estimated probable losses with respect to claims and legal proceedings were not considered material.

26.    FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

26.1     Financial risk factors

The Company is exposed to changes in financial market conditions in the normal course of business due to its operations in different foreign currencies and its ongoing investing and financing activities. The Company’s activities expose it to a variety of financial risks: market risk (including foreign exchange risk, fair value interest rate risk, cash flow interest rate risk and price risk), credit risk and liquidity risk. The Company’s overall risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the Company’s financial performance. The Company uses derivative financial instruments to hedge certain risk exposures.

Financial risk management is carried out by a central treasury department (Corporate Treasury). Additionally, a Treasury Committee, chaired by the Chief Financial Officer, steers treasury activities and ensures compliance with corporate policies. Treasury activities are thus regulated by the Company’s policies, which define procedures, objectives and controls. The policies focus on managing financial risk in terms of exposure to market risk, credit risk and liquidity risk. Treasury controls are subject to internal audits. Most treasury activities are centralized, with any local treasury activities subject to oversight from Corporate Treasury. Corporate Treasury identifies, evaluates and hedges financial risks in close cooperation with the Company’s subsidiaries. It provides written principles for overall risk management, as well as written policies covering specific areas, such as foreign exchange risk, interest rate risk, price risk, credit risk, use of derivative financial instruments, and investments of excess liquidity.

F-56

The majority of cash and cash equivalents is held in U.S. dollars and Euros and is placed with financial institutions rated at least a single “A” long-term rating from two of the major rating agencies, meaning at least A3 from Moody’s and A- from S&P and Fitch, or better. These ratings are closely and continuously monitored in order to manage exposure to the counterparty’s risk. Hedging transactions are performed only to hedge exposures deriving from operating, investing and financing activities conducted in the normal course of business.

Market risk

Foreign exchange risk

The Company conducts its business globally in various major international currencies. As a result, the Company is exposed to adverse movements in foreign currency exchange rates, primarily regarding the Euro. Foreign exchange risk mainly arises from recognized assets and liabilities at the Company’s subsidiaries and future commercial transactions.

Management has set up a policy to require the Company’s subsidiaries to hedge their entire foreign exchange risk exposure with the Company through financial instruments transacted or overseen by Corporate Treasury. Subsidiaries use forward contracts and purchased currency options to manage their foreign exchange risk arising from foreign-currency-denominated assets and liabilities. Foreign exchange risk arises when recognized assets and liabilities are denominated in a currency that is not the entity’s functional currency. These instruments do not qualify as hedging instruments for accounting purposes. Forward contracts and currency options, including collars, are also used by the Company to reduce its exposure to U.S. dollar fluctuations in Euro-denominated forecasted transactions that cover a large part of its R&D and corporate costs expenses as well as a portion of its front-end manufacturing costs of semi-finished goods. The Company also hedges through the use of currency forward contracts certain Singapore dollar-denominated manufacturing forecasted transactions. The derivative instruments used to hedge these forecasted transactions meet the criteria for designation as cash flow hedge. The hedged forecasted transactions have a high probability of occurring for hedge accounting purposes.

It is the Company’s policy to have the foreign exchange exposures in all the currencies hedged month by month against the monthly standard rate. At each month end, the forecasted flows for the coming month are hedged together with the fixing of the new standard rate. For this reason, the hedging transactions will have an exchange rate very close to the standard rate at which the forecasted flows will be recorded in the following month. As such, the foreign exchange exposure of the Company, which consists of the balance sheet positions and other contractually agreed transactions, is always close to zero and any movement in the foreign exchange rates will therefore not influence the exchange effect on items of the consolidated statement of income. Any discrepancy between the forecasted values and the actual results is constantly monitored and prompt actions are taken, if needed.

Derivative Instruments Not Designated as a Hedge

The Company enters into foreign currency forward contracts to reduce its exposure to changes in exchange rates and the associated risk arising from the denomination of certain assets and liabilities in foreign currencies at the Company’s subsidiaries. These include receivables from international sales by various subsidiaries, payables for foreign currency-denominated purchases and certain other assets and liabilities arising from intercompany transactions.

The notional amount of these financial instruments totaled $974 million, $931 million and $505 million on December 31, 2023, 2022 and 2021, respectively. The principal currencies covered at the end of the year 2023 are the China Yuan Renminbi, the Singapore dollar, the Euro, the Japanese yen, the Swiss franc, the Indian rupee, the Malaysian ringgit, the Moroccan dirham, the Philippines peso, the Swedish krona, the Taiwan dollar, and the South Korean won.

The risk of loss associated with forward contracts is equal to the exchange rate differential from the time the contract is entered into until the time it is settled. The risk of loss associated with purchased currency options is equal to the premium paid when the option is not exercised.

Foreign currency forward contracts not designated as cash flow hedge outstanding as of December 31, 2023 have remaining terms of 3 days to 166 days, maturing on average after 47 days.

F-57

Derivative Instruments Designated as a Hedge

To further reduce its exposure to U.S. dollar exchange rate fluctuations, the Company hedges through the use of currency forward contracts and currency options, including collars, certain Euro-denominated forecasted intercompany transactions that cover at year-end a large part of its R&D and SG&A expenses, as well as a portion of its front-end manufacturing costs of semi-finished goods within cost of sales. The Company also hedges through the use of currency forward contracts certain manufacturing transactions within cost of sales denominated in Singapore dollars.

The principles regulating the hedging strategy for derivatives designated as cash flow hedge are established as follows: (i) for R&D and corporate costs, up to 80% of the total forecasted transactions; (ii) for manufacturing costs, up to 70% of the total forecasted transactions. In order to follow a dynamic hedge strategy, the Company may change the percentage of the designated hedged item within the limit of 100% of the forecasted transaction. The maximum length of time over which the Company could hedge its exposure to the variability of cash flows for forecasted transactions is 24 months.

For the year ended December 31, 2023, the Company recorded a decrease in cost of sales of $1 million and a decrease in operating expenses of $4 million, related to the realized gains incurred on such hedged transactions. For the year ended December 31, 2022, the Company recorded an increase in cost of sales of $129 million and an increase in operating expenses of $68 million, related to the realized losses incurred on such hedged transactions. For the year ended December 31, 2021, the Company recorded a decrease in cost of sales of $15 million and a decrease in operating expenses of $4 million, related to the realized gains incurred on such hedged transactions.

The notional amount of foreign currency forward contracts and currency options, including collars, designated as cash flow hedge totaled $2,681 million, $3,192 million and $2,165 million on December 31, 2023, 2022 and 2021, respectively. The forecasted transactions hedged as of December 31, 2023 were determined to have a high probability of occurring.

As of December 31, 2023, $55 million of deferred gains on derivative instruments included in “Accumulated other comprehensive income (loss)” in the consolidated statements of equity were expected to be reclassified as earnings during the next 12 months based on the monthly forecasted R&D expenses, corporate costs and semi-finished manufacturing costs. Foreign currency forward contracts and collars designated as cash flow hedge outstanding as of December 31, 2023 have remaining terms of 4 days to 13 months, maturing on average after 113 days.

As of December 31, 2023, the Company had the following outstanding derivative instruments that were entered into to hedge Euro-denominated and Singapore dollar-denominated forecasted transactions:

In millions of Euros	Notional amount for hedge on forecasted R&D and other operating expenses	Notional amount for hedge on forecasted manufacturing costs
Forward contracts	445	951
Currency collars	240	640
In millions of Singapore dollars	Notional amount for hedge on forecasted R&D and other operating expenses	Notional amount for hedge on forecasted manufacturing costs
Forward contracts	—	219

Cash flow and fair value interest rate risk

The Company’s interest rate risk arises from long-term borrowings. Borrowings issued at variable rates expose the Company to cash flow interest rate risk. Borrowings issued at fixed rates expose the Company to fair value interest rate risk.

The Company analyses its interest rate exposure on a dynamic basis. Various scenarios are simulated taking into consideration refinancing, renewal of existing positions, alternative financing and hedging. The Company invests primarily on a short-term basis and as such the Company’s liquidity is invested in floating interest rate

F-58

instruments. As a consequence, the Company is exposed to interest rate risk due to potential mismatch between the return on its short-term floating interest rate investments and the portion of its long-term debt issued at fixed rate.

Price risk

As part of its ongoing investing activities, the Company may invest in publicly traded equity securities and be exposed to equity security price risk. In order to hedge the exposure to this market risk, the Company may enter into certain derivative hedging transactions.

Information on fair value of derivative instruments and their location in the consolidated balance sheets as of December 31, 2023 and December 31, 2022 is presented in the table below:

The Company entered into currency collars as combinations of two options, which are reported, for accounting purposes, on a net basis. As of December 31, 2023, the fair value of these collars represented assets for a net amount of $7 million (composed of $8 million assets offset with a $1 million liability). In addition, the Company entered into other derivative instruments, primarily forward contracts, which are governed by standard International Swaps and Derivatives Association (“ISDA”) agreements and are compliant with Protocols of the

F-59

European Market Infrastructure Regulation (“EMIR”), which are not offset in the statement of financial position and representing total assets of $53 million and liabilities of $4 million as of December 31, 2023.

The effect of derivative instruments designated as cash flow hedge on the consolidated statements of income for the year ended December 31, 2023 and December 31, 2022 and on the “Accumulated other comprehensive income (loss)” (“AOCI”) as reported in the consolidated statements of equity as of December 31, 2023 and December 31, 2022 is presented in the table below:

	Gain (loss) deferred in OCI on derivative		Location of gain (loss)	Gain (loss) reclassified from OCI into earnings

The Company did not enter into any derivative containing significant credit-risk-related contingent features.

  Credit risk

The expected credit loss and impairment methodology applied on each category of financial assets is further described in each respective note. While cash and cash equivalents are also subject to the expected credit loss model, the identified expected credit loss is deemed to be immaterial. The maximum credit risk exposure for all financial assets is their carrying amount.

Credit risk is the risk that a counterparty will not meet its obligations under a financial instrument or customer contract, leading to a financial loss. Credit risk typically arises from cash and cash equivalents, contractual cash flows of debt investments carried at amortized cost, the counterparty of derivative financial instruments and deposits with banks and financial institutions, as well as credit exposure to customers, including outstanding receivables.

F-60

The Company is exposed to credit risk from its operating activities (primarily for trade receivables) and from its financing activities, including deposits with banks and financial institutions, foreign exchange transactions and other financial instruments. Credit risk is managed at the Group level. The Company selects banks and/or financial institutions that operate with the group based on the criteria of long-term rating from at least two major Rating Agencies and keeping a maximum outstanding amount per instrument with each bank not to exceed 20% of the total. For derivative financial instruments, management has established limits so that, at any time, the fair value of contracts outstanding is not concentrated with any individual counterparty.

The Company monitors the creditworthiness of its customers to which it grants credit terms in the normal course of business. If certain customers are independently rated, these ratings are used. Otherwise, if there is no independent rating, risk control assesses the customer’s credit quality, considering its financial position, past experience and other factors. The utilization of credit limits is regularly monitored. Sales to customers are primarily settled in cash, which mitigates credit risk. As of December 31, 2023 and 2022, no customer represented more than 10% of trade accounts receivable, net. Any remaining concentrations of credit risk with respect to trade receivables are limited due to the large number of customers and their dispersion across many geographic areas.

The Company’s investments in instruments carried at amortized cost primarily include receivables towards government bodies. As such, they are investments with immaterial expected credit loss. Any remaining receivable is of low credit risk and is individually not significant. The credit ratings of the investments are monitored for credit deterioration.

Liquidity risk

Prudent liquidity risk management includes maintaining sufficient cash and cash equivalents, short-term deposits and marketable securities, the availability of funding from committed credit facilities and the ability to close out market positions. The Company’s objective is to maintain a significant cash position and a low debt-to-equity ratio, which ensures adequate financial flexibility. Liquidity management policy is to finance the Company’s investments with net cash from operating activities.

Management monitors rolling forecasts of the Company’s liquidity reserve based on expected cash flows.

26.2     Capital risk management

The Company’s objectives when managing capital are to safeguard the Company’s ability to continue as a going concern in order to create sustainable value, benefits and returns for its stakeholders, as to maintain an optimal capital structure. In order to maintain or adjust its capital structure, the Company may review the amount of dividends paid to shareholders, return capital to shareholders, or issue new shares.

Consistent with other peers in the industry, the Company monitors capital on the basis of the net debt-to-equity ratio. This ratio is calculated as the net financial position of the Company, defined as the difference between total cash position (cash and cash equivalents, short-term deposits, marketable securities and restricted cash, if any) and total financial debt (short-term and long-term debt), divided by total parent company stockholders’ equity.

26.3     Fair value measurement

The fair value of financial instruments traded in active markets is based on quoted market prices at the balance sheet date. The quoted market price used for financial assets held by the Company is the bid price. If the market for a financial asset is not active and if no observable market price is obtainable, the Company measures fair value by using significant assumptions and estimates. When measuring fair value, the Company makes maximum use of market inputs and minimizes the use of unobservable inputs.

Contingent consideration reported as liabilities on the consolidated balance sheet as of December 31, 2023 and December 31, 2022 is based on the probability that the milestones defining the variable components of the

F-62

consideration will be achieved. In 2023, the probability of achievement of these variable components was reassessed, resulting in a reduction of $12 million of the fair value of the contingent consideration related to a certain business acquisition from 2020. The Company reported this change in fair value in the line “Research and development expenses” of the consolidated statement of income.

For liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3), the reconciliation between January 1, 2022 and December 31, 2022 is presented as follows:

The fair value represented the market price of the bonds trading on the Frankfurt Stock Exchange.

F-63

The methodologies used to estimate fair value are as follows:

Components	Methodology used to estimate fair value
Debt securities classified as available-for-sale	Quoted market prices for identical instruments
Foreign exchange forward contracts, currency options and collars	Quoted market prices for similar instruments
Equity securities measured at fair value through earnings	Quoted market prices for identical instruments
Equity securities carried at cost as a measurement alternative	Valuation of the underlying investments on a new round of third-party financing or upon liquidation
Long-term debt and current portion of long-term debt	Future cash flows on a borrowing-by-borrowing basis and discounting these future cash flows using the Company's incremental borrowing rates for similar types of borrowing arrangements. For convertible bonds, the fair value represents the market price of the bonds trading on the Frankfurt Stock Exchange
Cash and cash equivalents, short-term deposits, accounts receivable, short-term borrowings, and accounts payable	The carrying amounts reflected in the consolidated financial statements are considered as reasonable estimates of fair value due to the relatively short period of time between the origination of the instruments and their expected realization.

27.    RELATED PARTY TRANSACTIONS

The below table summarizes transactions incurred in 2023, 2022 and 2021 with companies for which certain members of the Company’s management perform similar policymaking functions. These include, but are not limited to: Orange, Idemia France and Politecnico di Milano. The amounts reported on the below table correspond to transactions up to the date members of the Company's management hold these similar functions.

	2023	2022	2021
Sales and services	5	13	8
Purchases and other contributions	27	25	19
Accounts receivable	—	5	2
Accounts payable	6	2	—

The Company did not hold any significant equity-method investments as of December 31, 2023, 2022 and 2021. Consequently, the Company did not report any material transaction with this type of investees in the corresponding years.

The Company made a cash contribution of $1 million for the year ended December 31, 2023 to the ST Foundation, a non-profit organization established to deliver and co-ordinate independent programs in line with its mission. A cash contribution of $1.0 million and $0.5 million was made for each of the years ended December 31, 2022 and 2021, respectively. Certain members of the Foundation’s Board are senior members of the Company’s management.

28.    SUBSEQUENT EVENTS

In the first quarter of 2024, the Company announced its product group reorganization to further accelerate the Company's time-to-market and speed of product development innovation and efficiency. This new organization implies a change in segment reporting which will be applied in 2024.

STMICROELECTRONICS N.V.
STATEMENT OF COMPLIANCE WITH SECTION 303A.14 OF THE NEW YORK STOCK EXCHANGE LISTED COMPANY MANUAL

STMicroelectronics N.V. (the “Company”) has adopted this Statement of Compliance with Section 303A.14 of the New York Stock Exchange Listed Company Manual (this “Statement”) in accordance with the applicable provisions of The New York Stock Exchange Listed Company Manual (the “Clawback Rules”), promulgated pursuant to the final rules adopted by the Securities and Exchange Commission enacting the clawback standards under Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act. Capitalized terms not otherwise defined in this Statement have the meanings given to them under the Clawback Rules.

I.Recovery of Erroneously Awarded Compensation.

The Company shall comply with the Clawback Rules and reasonably promptly recover Erroneously Awarded Compensation Received by current or former Executive Officers of the Company (“Covered Individuals”) in the event the Company is required to prepare an accounting restatement due to the Company’s material noncompliance with any financial reporting requirement under the securities laws, including any required accounting restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. The Administrator may determine not to recover Erroneously Awarded Compensation pursuant to this Statement in circumstances where non-enforcement is expressly permitted by the Clawback Rules, including where recovery would violate applicable Dutch laws in effect before November 28, 2022.

II.Covered Individuals.

The Administrator shall determine the Company’s Covered Individuals, an initial list of whom is set forth as Annex A, which may be updated by the Administrator from time to time.

III.Covered Compensation.

This Statement applies to the Incentive-Based Compensation Received by a Covered Individual: (1) after such Covered Individual began service as an Executive Officer; (2) who served as an Executive Officer at any time during the performance period for that Incentive-Based Compensation; (3) while the Company has a class of securities listed on a national securities exchange or a national securities association; and (4) during the three completed fiscal years immediately preceding the date that the Company is required to prepare an accounting restatement as described above (or during any transition period, that results from a change in the Company’s fiscal year, within or immediately following those three completed fiscal years, as determined in accordance with the Clawback Rules). Notwithstanding the foregoing, this Statement shall not apply to Incentive-Based Compensation Received by a Covered Individual prior to October 2, 2023.

The amount of Incentive-Based Compensation subject to this Statement is the Erroneously Awarded Compensation, which is be the amount of Incentive-Based Compensation Received by a Covered Individual that exceeds the amount of Incentive-Based Compensation that otherwise would have been Received by the Covered Individual had it been determined based on the restated amount (or otherwise determined in accordance with the Clawback Rules), and will be computed without regard to any taxes paid by the Covered Individual (or withheld from the Incentive-Based Compensation). The Administrator shall make all determinations regarding the amount of Erroneously Awarded Compensation.

IV.Method of Recovery.

The Administrator shall determine, in its sole discretion, the manner in which any Erroneously Awarded Compensation shall be recovered to the extent permitted under the Clawback Rules, which method of recovery need not be uniform with respect to each Covered Individual. Methods of recovery may include, but are not limited to: (1) seeking direct repayment from the Covered Individual; (2) reducing (subject to applicable law and the terms and conditions of the applicable plan, program or arrangement pursuant to which the Incentive-Based Compensation was paid) the amount that would otherwise be payable to the Covered Individual under any compensation, bonus, incentive, equity and other benefit plan, agreement, policy or arrangement maintained by the Company or any of its affiliates; (3) cancelling any award (whether cash- or equity-based) or portion thereof previously granted to the Covered Individual; or (4) any combination of the foregoing.

V.No-Fault Basis.

This Statement applies on a no-fault basis, and Covered Individuals will be subject to recovery under this Statement without regard to their personal culpability.

VI.Other Company Arrangements.

This Statement shall be in addition to, and not in lieu of, any other clawback, recovery or recoupment framework maintained by the Company from time to time, as well as any clawback, recovery or recoupment provision in any of the Company’s plans, awards or individual agreements (including the clawback, recovery and recoupment provisions in the Company’s equity award agreements) (collectively, “Other Company Arrangement”) and any other rights or remedies available to the Company, including termination of employment; provided, however, that there is no intention to, nor shall there be, any duplicative recoupment of the same compensation under more than one policy, plan, award or agreement. In addition, no Other Company Arrangement shall serve to restrict the scope or the recoverability of Erroneously Awarded Compensation under this Statement or in any way limit recovery in compliance with the Clawback Rules.

VII.No Indemnification.

Notwithstanding anything to the contrary set forth in any policy, arrangement, bylaws, charter, certificate of incorporation or plan of the Company or any individual agreement between a Covered Individual and the Company or any of its affiliates, no Covered Individual shall be entitled to indemnification from the Company or any of its affiliates for the amount that is or may be recovered by the Company pursuant to this Statement; provided, however, that to the extent expense advancement or reimbursement is available to a Covered Individual, this Statement shall not serve to prohibit such advancement or reimbursement.

VIII.Administration; Interpretation.

This Statement was adopted by the Company through its Supervisory Board and Managing Board pursuant to their authority under the relevant Dutch statutory provisions. The Managing Board may delegate administration of this Statement to the Supervisory Board as allowed by the Clawback Rules, the Company’s organizational documents and applicable law. The Compensation Committee of the Supervisory Board shall advise the Supervisory Board in its capacity as “Administrator” for purposes of this Statement.

The Administrator shall interpret and construe this Statement consistent with the Clawback Rules and applicable laws and regulations and shall make all determinations necessary, appropriate or

50113732 M 53662564 / 1

advisable for the administration of this Statement. Any determinations made by the Administrator shall be final, binding and conclusive on all affected individuals. As required by the Clawback Rules, the Company shall provide public disclosures related to this Statement and any applicable recoveries of Erroneously Awarded Compensation. To the extent this Statement conflicts or is inconsistent with the Clawback Rules, the Clawback Rules shall govern. In no event is this Statement intended to be broader than, or require recoupment in addition to, that required pursuant to the Clawback Rules.

IX.Amendment or Termination

The Company reserves the right to amend this Statement at any time and for any reason, subject to applicable law and the Clawback Rules. To the extent that the Clawback Rules cease to be in force or cease to apply to the Company, this Statement shall also cease to be in force.

Approved and Adopted: October 25, 2023

Accounting Policies [Abstract]

Accounting Policies

ACCOUNTING POLICIES

The accounting policies of the Company conform to accounting principles generally accepted in the United States of America (“U.S. GAAP”). All balances and values in the current and prior periods are in millions of U.S. dollars, except share and per-share amounts. Under Article 35 of the Company’s Articles of Association, the financial year extends from January 1 to December 31, which is the period-end of each fiscal year.

2.1     Basis of presentation and consolidation

The Company's consolidated financial statements include the assets, liabilities, results of operations and cash flows of its wholly-owned and majority-owned subsidiaries, after elimination of intercompany transactions and balances. Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are deconsolidated from the date that control ceases.

The Company assesses each investment in equity securities to determine whether the investee is a Variable Interest Entity (“VIE”). The Company consolidates the VIEs for which the Company is determined to be the primary beneficiary. The primary beneficiary of a VIE is the party that: (i) has the power to direct the most significant activities of the VIE and (ii) is obligated to absorb losses or has the rights to receive returns that would be considered significant to the VIE.

When the Company owns some, but not all, of the voting stock of a consolidated entity, the shares held by third parties represent a noncontrolling interest. The consolidated financial statements are prepared based on the total amount of assets and liabilities and income and expenses of the consolidated subsidiaries. However, the portion of these items that does not belong to the Company’s shareholders is reported in the line “Noncontrolling interest” of the consolidated financial statements.

2.2     Use of estimates

The preparation of consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions. The primary areas that require significant estimates and judgments by management include, but are not limited to:

•sales allowances for discounts, price protection, product returns and other rebates,

•inventory obsolescence reserves and normal manufacturing capacity thresholds to determine costs capitalized in inventory,

•recognition and measurement of loss contingencies,

•valuation at fair value of assets acquired and liabilities assumed on business acquisitions, and measurement of any contingent consideration,

•annual and trigger-based impairment review of goodwill and intangible assets, as well as the assessment of events which could trigger impairment testing on tangible assets,

•assessment of the Company’s long-lived assets economic useful lives,

•assumptions used in measuring expected credit losses and impairment charges on financial assets,

•assumptions used in assessing the number of awards expected to vest on stock-based compensation plans,

•assumptions used in calculating net defined pension benefit obligations and other long-term employee benefits,

•determination of the amount of tax expected to be paid and tax benefit expected to be received, including deferred income tax assets, valuation allowance and provisions for uncertain tax positions and claims.

The Company bases the estimates and assumptions on historical experience and on various other factors such as market trends, market information used by market participants and the latest available business plans that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. While the Company regularly evaluates its estimates and assumptions, the actual results experienced by the Company could differ materially and adversely from those estimates.

2.3     Foreign currency

The U.S. dollar is the reporting currency of the Company. The U.S. dollar is the currency of the primary economic environment in which the Company operates since the worldwide semiconductor industry uses the U.S. dollar as a currency of reference for actual pricing in the market. Furthermore, the majority of the Company’s transactions are denominated in U.S. dollars, and revenues from external sales in U.S. dollars largely exceed revenues in any other currency. However, certain significant costs are incurred in the countries of the Eurozone and other non-U.S. dollar currency areas.

The functional currency of each subsidiary of the Company is either the local currency or the U.S. dollar, depending on the basis of the economic environment in which each subsidiary operates. Foreign currency transactions, including operations in local currency when the U.S. dollar is the functional currency, are measured into the functional currency using the prevailing exchange rate. Foreign exchange gains and losses resulting from the re-measurement at reporting date of monetary assets and liabilities denominated in currencies other than the functional currency are recognized in the line “Other income and expenses, net” of the consolidated statements of income.

For consolidation purposes, the results and financial position of the subsidiaries whose functional currency is different from the U.S. dollar are translated into the reporting currency as follows:

(a)assets and liabilities for each consolidated balance sheet presented are translated into U.S. dollars using exchange rates at the balance sheet dates;

(b)income and expenses for each consolidated statement of income presented are translated into U.S dollars using the monthly exchange rates;

(c)the resulting exchange differences are reported as Currency Translation Adjustments (“CTA”), a component of “Other comprehensive income (loss)” in the consolidated statements of comprehensive income.

2.4     Cash and cash equivalents

Cash and cash equivalents include cash on hand, deposits held at call with external financial institutions and other short-term highly liquid investments with effective maturities of three months or less. They are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates.

Short-term deposits representing cash equivalents with maturity beyond three months and below one year are reported as current assets in the line “Short-term deposits” of the consolidated balance sheets.

2.5     Trade accounts receivable

Trade accounts receivable are amounts due from customers for goods sold and services rendered to third parties in the ordinary course of business. The Company uses a lifetime expected losses allowance for all trade receivables. The allowance includes reasonable assumptions about future credit trends. The historical loss rates are adjusted to reflect current and forward-looking information on macro-economic factors affecting the ability of the Company’s customers to settle the receivables. Adjustments to the expected credit losses allowance are reported on the line “Selling, general and administrative expenses” in the consolidated statements of income and write-offs, if any, are recorded against the expected credit losses allowance.

In the event of transfers of receivables such as factoring, the Company derecognizes the receivables only to the extent that the Company has surrendered control over the receivables in exchange for a consideration other than beneficial interest in the transferred receivables.

2.6     Inventories

Inventories are stated at the lower of cost and net realizable value. Actual cost is based on an adjusted standard cost, which approximates cost on a first-in, first-out basis for all categories of inventory (raw materials, work-in-process, finished products). Actual cost is therefore dependent on the Company’s manufacturing performance and is based on the normal utilization of its production capacity. In case of underutilization of manufacturing facilities, the costs associated with unused capacity are not included in the valuation of inventories but charged directly to cost of sales. Net realizable value is based upon the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation.

Inventory reserve is estimated for excess uncommitted inventory based on historical sales data, order backlog and production plans. The Company performs, on a continuous basis, write-offs of inventories, which have the characteristics of slow-moving, old production dates and technical obsolescence. The Company evaluates its inventory to identify obsolete or slow-selling items, as well as inventory that is not of saleable quality and records a specific reserve if the Company estimates the inventory will eventually be written off.

2.7     Income taxes

Income tax for the period comprises current and deferred income tax. Income tax expense represents the income tax expected to be paid related to the current year taxable profit in each tax jurisdiction. Deferred income tax is recognized for all temporary differences arising between the tax bases of assets and liabilities and their carrying amount in the consolidated financial statements. Deferred tax assets are also recognized on temporary differences arising from tax losses carried forward and tax credits. Deferred tax liabilities are not recognized on the initial recognition of goodwill as a result of a business combination. Deferred income tax is determined using tax rates and laws that are enacted at the balance sheet date and are expected to apply when the related deferred income tax asset is realized or the deferred income tax liability is settled. The effect on deferred tax assets and liabilities from changes in tax laws and tax rates is recognized on the line “Income tax expense” in the consolidated statements of income in the period in which the law is enacted. Deferred income tax assets are recognized in full but the Company assesses whether future taxable profit will be available against which temporary differences can be utilized. A valuation allowance is provided for deferred tax assets when management considers it is more likely than not that they will not be realized.

The Company recognizes a deferred tax liability on undistributed earnings of subsidiaries when there is a presumption that taxable earnings will be remitted to the parent. A deferred tax asset is recognized on

compensation for the grant of stock awards to the extent that such charge constitutes a temporary difference in the subsidiaries’ local tax jurisdictions. Changes in the stock price do not result in any adjustments to the deferred tax asset prior to vesting.

At each reporting date, the Company assesses all significant income tax positions in all tax jurisdictions to determine any uncertain tax positions. The Company uses a two-step process for the evaluation of uncertain tax positions. The first step consists in assessing whether the tax benefit must be recognized. The second step consists in measuring the amount of tax benefit to be recognized on each uncertain tax position. In step 1 (recognition), the Company assesses whether a tax position, based solely on its technical merits, is more likely than not to be sustained upon examination. Only tax positions with a sustainability threshold higher than 50% are recognized. In Step 2 (measurement), the Company determines the amount of recognizable tax benefit. The measurement methodology is based on a “cumulative probability” approach, resulting in the recognition of the largest amount that is greater than 50% likely of being realized upon settlement with the taxing authority. The Company accrues for interest and penalties on uncertain tax liabilities reported on the consolidated balance sheets. Interests and penalties are classified as components of income tax expense in the consolidated statements of income.

2.8     Business combinations and goodwill

The acquisition method of accounting is applied to all business combinations. The identifiable assets acquired, liabilities assumed, and equity instruments issued are measured at acquisition date fair value. Any contingent consideration is recorded at acquisition date fair value and remeasured at each reporting date. Acquisition-related transaction costs and restructuring costs related to the acquired business are expensed as incurred. Acquired in-process research and development (“IPR&D”) is capitalized and recorded as an intangible asset at acquisition date, subject to impairment testing until the research or development is completed. The excess of the consideration transferred over the acquisition-date fair value of the identifiable assets acquired and liabilities assumed, net of related deferred tax impacts, is recorded as goodwill. In case of a bargain purchase, the Company reassesses whether it has correctly identified all of the assets acquired and all of the liabilities assumed, the noncontrolling interest in the acquiree, if any, the Company’s previously held equity interest in the acquiree, if any, and the consideration transferred. If after this review, a bargain purchase is still indicated, it is recognized in earnings attributable to parent company stockholders. The purchase of additional interests in a partially owned subsidiary is treated as an equity transaction as well as all transactions concerning the sale of subsidiary stock or the issuance of stock by the partially owned subsidiary, assuming there is no change in control of the subsidiary. In the case of a sale of subsidiary shares, whereby the Company no longer maintains control of the subsidiary, the Company recognizes a gain or loss in earnings.

Goodwill is carried at cost less accumulated impairment losses, if any. Goodwill is not amortized but is tested for impairment at least annually, and more frequently whenever events or changes in circumstances indicate that the carrying amount of goodwill may not be recoverable. Goodwill subject to potential impairment is tested at the reporting unit level. The impairment test determines whether the fair value of each reporting unit under which goodwill is allocated is lower than the total carrying amount of relevant net assets allocated to such reporting unit, including its allocated goodwill. The Company records an impairment loss on goodwill when a reporting unit’s carrying value exceeds its fair value. Significant management judgments and estimates are used in forecasting the future discounted cash flows associated with the reporting unit, including: the applicable industry’s sales volume forecast and selling price evolution, the reporting unit’s market penetration and its revenues evolution, the market acceptance of certain new technologies and products, the relevant cost structure, the discount rates applied using a weighted average cost of capital and the perpetuity rates used in calculating cash flow terminal values.

2.9     Intangible assets with definite useful lives

Intangible assets subject to amortization include intangible assets purchased from third parties recorded at cost and intangible assets acquired in business combinations initially recorded at fair value. Amortization begins when the intangible asset is available for its intended use. Amortization reflects the pattern in which the asset’s economic benefits are consumed, which usually consists in applying the straight-line method to allocate the cost of the intangible assets over their estimated useful lives.

The carrying value of intangible assets with definite useful lives is evaluated whenever changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for

the amount by which the asset’s carrying amount exceeds its fair value. The Company evaluates the remaining useful life of an intangible asset at each reporting date to determine whether events and circumstances warrant a revision to the remaining period of amortization.

Technologies and licenses

Separately acquired technologies and licenses are recorded at historical cost. Technologies and licenses acquired in a business combination are initially recognized at acquisition date fair value. Technologies and licenses have a useful life which usually ranges from 3 to 11 years and are carried at cost less accumulated amortization and impairment losses, if any.

Computer software

Separately acquired computer software is recorded at historical cost. Costs associated with maintaining computer software programs are expensed as incurred and reported as “Cost of sales”, “Selling, general and administrative expenses”, or “Research and development expenses” in the consolidated statements of income according to their intended use. The capitalization of costs for internally generated software developed by the Company for its internal use begins when the preliminary project stage is completed and when the Company, implicitly or explicitly, authorizes and commits to funding a computer software project. It must be probable that the project will be completed and will be used to perform the function intended. Amortization of computer software begins when the software is available for its intended use and is calculated using the straight-line method over the estimated useful life, which does not exceed 4 years.

2.10     Property, plant and equipment

Property, plant and equipment are stated at historical cost, net of accumulated depreciation and any impairment losses. Property, plant and equipment acquired in a business combination are initially recognized at acquisition date fair value. Major additions and improvements are capitalized, while minor replacements and repairs are expensed and reported as “Cost of sales”, “Selling, general and administrative expenses”, or “Research and development expenses” in the consolidated statements of income according to their intended use.

Land is not depreciated. Depreciation on fixed assets is computed using the straight-line method over their estimated useful lives, as follows:

Buildings	33 years
Facilities and leasehold improvements	5-10 years
Machinery and equipment	2-10 years
Computer and R&D equipment	3-6 years
Other	2-5 years

The Company also evaluates, and adjusts if appropriate, the assets’ useful lives.

Property, plant and equipment are periodically reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or a group of assets may not be recoverable. Several impairment indicators exist for making this assessment, such as: restructuring plans, significant changes in the technology, market, economic or legal environment in which the Company operates, available evidence of obsolescence of the asset, or indication that its economic performance is, or will be, worse than expected. In determining the recoverability of assets to be held and used, the Company initially assesses whether the carrying value of the tangible assets or group of assets exceeds the undiscounted cash flows associated with these assets. If exceeded, the Company then evaluates whether an impairment charge is required by determining if the asset’s carrying value also exceeds its fair value. This fair value is normally estimated by the Company based on independent market appraisals or the sum of discounted future cash flows, using market assumptions such as the utilization of the Company’s fabrication facilities and the ability to upgrade such facilities, change in the selling price and the adoption of new technologies. Any impairment loss is reported on the same income statement line as the depreciation expense recorded on the impaired group of assets, except in case of closure of operating sites or major restructuring plans and reorganizations. In such case, any impairment loss is reported on the line “Impairment, restructuring charges and other related closure costs” in the consolidated statements of income.

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are included in “Other income and expenses, net” in the consolidated statements of income.

The Company did not hold any significant assets held for sale as of December 31, 2023 and December 31, 2022.

2.11     Leases

A lease contract is a contract, or part of a contract, that conveys the right to control the use of an identified asset for a period of time in exchange for consideration. If a lease is identified, classification between finance or operating is determined at lease commencement. Most leases entered by the Company are operating leases. Operating lease liabilities are recognized at the present value of the future lease payments at the lease commencement date. The rate implicit in the lease should be used as a discount rate whenever that rate is readily determinable. In most cases, this rate is not readily determinable and therefore, the Company uses its incremental borrowing rate, which is derived from information available at the lease commencement date. The Company considers its recent debt issuances as well as publicly available data for instruments with similar characteristics when calculating its incremental borrowing rates. Operating lease right-of-use assets are based on the corresponding lease liability adjusted for any lease payments made at or before commencement, initial direct costs, and lease incentives.

Right-of-use assets are included in the line “Property, plant and equipment, net” of the consolidated balance sheets. Operating lease liabilities due within one year are included in the line “Other payables and accrued liabilities”, while non-current operating lease liabilities are included in the line “Other long-term liabilities” of the Company’s consolidated balance sheets. Operating lease expenses are recognized in the consolidated statements of income, on a straight-line basis since the lease commencement date over the lease period and reported as “Cost of sales”, “Selling, general and administrative expenses”, or “Research and development expenses”, according to the intended use of the leased asset.

Finance lease liabilities due within one year are included in the line “Short-term debt”, while non-current finance lease liabilities are included in the line “Long-term debt” of the Company’s consolidated balance sheets. Right-of-use assets for finance leases are depreciated on a straight-line basis since the lease commencement date over the lease period or the estimated useful life of the leased asset in case of transfer of ownership or purchase option that is reasonably certain to be exercised. The depreciation expense is reported as “Cost of sales”, “Selling, general and administrative expenses”, or “Research and development expenses”, according to the intended use of the leased asset.

Certain lease contracts contain options to extend the lease. On these contracts, the Company estimates the lease term by including the extended duration when it is reasonably certain for the Company to exercise that option. In addition, for short-term leases, defined as leases with a term of twelve months or less, the Company elected the practical expedient to not recognize an associated lease liability and right-of-use asset. The short-term lease election is made at the commencement date only. Additionally, lease contracts with a sum of lease payments not exceeding $5,000 are excluded from recognition on the consolidated balance sheet.

The right-of-use asset is a non-monetary asset while the lease liability is a monetary liability. When accounting for a lease that is denominated in a foreign currency, the lease liability is remeasured using the current exchange rate, while the right-of-use asset is measured using the historical exchange rate as of the commencement date.

The Company does not separate lease and non-lease components and instead accounts for each separate lease component and the non-lease components associated with that lease component as a single lease component.

Variable lease payments that depend on an index or a rate are included in the lease payments and are measured using the prevailing index or rate at the measurement date. Changes to index and rate-based variable lease payments are recognized in earnings in the period of the change.

2.12     Loss contingencies

In determining loss contingencies, the Company considers the likelihood of the incurrence of a liability as well as the ability to reasonably estimate the amount of such loss or liability. An estimated loss from a loss contingency is accrued when information available indicates that it is probable that a liability has been incurred at the date of the consolidated financial statements and when the amount of the loss can be reasonably estimated.

2.13     Long-term debt

(a)Convertible debt

On January 1, 2022, the Company adopted the new guidance on distinguishing liabilities from equity by applying the modified retrospective approach, with the impact upon transition recorded in retained earnings for instruments outstanding as of the date of adoption of the new guidance. Prior to the new guidance, components of convertible debt instruments that may be settled in cash upon conversion based on a net-share settlement basis were accounted for separately as long-term debt and equity when the conversion feature of the convertible bonds constituted an embedded equity instrument. When an equity instrument was identified, proceeds from issuance were allocated between debt and equity by measuring first the liability component and then determining the equity component as a residual amount. The liability component was measured as the fair value of a similar non-convertible debt, which resulted in the recognition of a debt discount. In subsequent periods, the Company amortized the debt discount through earnings in the line “Interest income (expense), net” of the consolidated statements of income, using the effective interest method, based on the contractual maturity of the debt. The equity component, reported on the line “Additional paid-in capital” of the consolidated statement of equity, was not remeasured. Deferred taxes were recognized on the difference between the carrying amount of the liability component and its tax basis. In case of conversion from the bondholders, the fair value of the consideration transferred was allocated between the liability component and the equity component. The difference between the carrying amount of the debt at the settlement date and the fair value of the debt component was recorded in earnings as a loss on debt extinguishment and reported in the line “Loss on financial instruments, net” of the consolidated statements of income. The liability component was measured as the fair value of a similar non-convertible debt prior to settlement. The reacquired equity component was recorded in equity and reported on the line “Additional paid-in capital” of the consolidated statement of equity.

The new accounting guidance adopted on January 1, 2022 has eliminated the cash conversion model described above. At initial recognition, total cash proceeds received at issuance are reported as financial debt and no equity conversion instrument is recorded separately in equity. On subsequent periods, the carrying value of the convertible debt is incremented up to its nominal value over the amortization pattern of any unamortized debt discount and issuance costs.

Debt issuance costs are reported as a deduction of debt. They are subsequently amortized through earnings on the line “Interest income (expense), net” of the consolidated statements of income, using the effective interest rate method.

(b)Bank loans

Bank loans and non-convertible senior bonds are recognized at the amount of cash proceeds received, net of debt issuance costs incurred. They are subsequently reported at amortized cost; any difference between the proceeds (net of debt issuance costs) and the principal amount is recognized through earnings on the line “Interest income (expense), net” of the consolidated statements of income over the period of the borrowings using the effective interest method.

2.14     Employee benefits

(a) Pension obligations

The Company sponsors various pension schemes for its employees. These schemes conform to local regulations and practices in the countries in which the Company operates. Such plans include both defined benefit and defined contribution plans. For defined benefit pension plans, the liability recognized in the consolidated balance sheets is the present value of the defined benefit obligation at the balance sheet date less the fair value of plan assets. The funded status of the defined benefit plans is calculated as the difference between plan assets and the projected benefit obligations. Estimates are used in determining the assumptions incorporated in the calculation of the pension obligations, which is supported by input from independent actuaries. Actuarial gains and losses arising from changes in actuarial assumptions are recognized in “Accumulated other comprehensive income (loss)” in the consolidated statements of equity and are charged or credited to earnings over the employees’ average remaining service period using the corridor amortization method. Past service costs are recognized in earnings on the line “Other components of pension benefit costs” of the consolidated statements of income if the changes to the pension scheme are not conditional on the employees remaining in service for a specified period. Other past service costs are recognized in “Accumulated other comprehensive income (loss)”

in the consolidated statements of equity and are amortized on a straight-line basis over the average remaining service period. The net periodic benefit cost of the year is determined based on the assumptions used at the end of the previous year.

The service cost component of net periodic benefit costs is presented in the same income statement line as other employee compensation costs arising from services rendered during the period. The other components of the net periodic benefit cost are presented separately, outside operating income, on the line “Other components of pension benefit costs” of the consolidated statements of income. These elements include: interest cost; expected return on plan assets; amortization of transition (asset) obligation; amortization of prior service cost; amortization of net (gain) loss; (gain) loss recognized due to curtailment or settlement and; cost of special termination benefits.

For defined contribution pension plans, the Company pays contributions to publicly or privately administered pension insurance plans on a mandatory, contractual or voluntary basis. The Company has no further payment obligations once the contributions have been paid. The contributions are recognized as employee benefit expense when they are due. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in the future payments is available.

(b) Termination benefits

Termination benefits are payable when an employee is involuntarily terminated, or whenever an employee accepts voluntary termination in exchange for termination benefits. For the accounting treatment and timing of recognition of involuntary termination benefits, the Company distinguishes between one-time termination benefit arrangements and ongoing termination benefit arrangements. A one-time termination benefit arrangement is established by a termination plan and applies to a specified termination event. One-time involuntary termination benefits are recognized as a liability when the termination plan meets certain criteria and has been communicated to employees. If employees are required to render future service in order to receive these one-time termination benefits, the liability is recognized ratably over the future service period. Termination benefits other than one-time termination benefits are termination benefits for which the communication criterion is not met but that are committed to by management, or termination obligations that are not specifically determined in a new and single plan. These termination benefits are all legal, contractual and past practice termination obligations to be paid to employees in case of involuntary termination. These termination benefits are accrued for when commitment creates a present obligation to others for the benefits expected to be paid, when it is probable that employees will be entitled to the benefits and the amount can be reasonably estimated.

In case of special termination benefits related to voluntary redundancy programs, the Company recognizes a provision for voluntary termination benefits at the date on which the employee irrevocably accepts the offer and the amount can be reasonably estimated.

(c) Profit-sharing and bonus plans

The Company recognizes a liability and an expense for bonuses and profit-sharing plans when a contractual obligation exists or when there is a past practice that has created a present obligation.

(d) Other long-term employee benefits

The Company provides long-term employee benefits such as seniority awards in certain countries. The entitlement to these benefits is usually conditional on the employee completing a minimum service period. The expected costs of these benefits are accrued over the period of employment. Actuarial gains and losses arising from changes in actuarial assumptions are charged or credited to earnings in the period of the revised estimate. These obligations are valued annually with the assistance of independent qualified actuaries.

(e) Share-based compensation

The Company accounts for stock-based compensation for all stock-based awards granted to senior executives and selected employees, including awards that vest upon the satisfaction of a service condition and awards that vest upon the satisfaction of both a service condition and a performance condition. Both equity awards vest over

a three-year service period while performance-based awards also require the Company’s attainment of certain performance conditions. The Company measures the cost of the awards based on the related grant-date fair value, reflecting the market price of the underlying shares at the date of the grant, reduced by the present value of the dividends expected to be paid during the requisite service period. That cost is recognized ratably over the period during which an employee is required to provide service in exchange for the award. The compensation cost is recorded through earnings with the corresponding amount reported in equity, under “Additional paid-in capital” of the consolidated statements of equity. The compensation cost is calculated based on the number of awards expected to vest, net of an estimated number of awards to be forfeited due to the employees failing to satisfy the service condition or one or more performance conditions. By the end of the vesting period, compensation is recognized only for the awards that ultimately vest.

Liabilities for the Company’s portion of payroll taxes are recognized at vesting, which is the event triggering the payment of the social contributions in most of the Company’s local tax jurisdictions. Employee-related social charges are measured based on the intrinsic value of the share and recorded at vesting date.

2.15     Share capital

Ordinary shares are classified as “Common stock” within equity on the consolidated balance sheets. Incremental costs directly attributable to the issuance of new shares are shown in equity as a deduction, net of tax, from the proceeds received.

Where the Company purchases its own equity share capital (treasury stock), the consideration paid, including any directly attributable incremental costs (net of income taxes), is deducted from parent company stockholders’ equity until the shares are cancelled, reissued, or disposed of.

2.16     Comprehensive income (loss)

Comprehensive income (loss) is defined as the change in equity of a business during a period except those changes resulting from investment by and distributions to stockholders. In the consolidated financial statements, “Other comprehensive income (loss)” and “Accumulated other comprehensive income” primarily consists of foreign currency translation adjustments, unrealized gains (losses) on debt securities classified as available-for-sale, unrealized gains (losses) on derivatives designated as cash flow hedge and the accounting for defined benefit plans, net of tax.

2.17     Revenue recognition

Arrangements with customers are considered contracts if all the following criteria are met: (a) parties have approved the contract and are committed to perform their respective obligations; (b) each party’s rights regarding the goods or services to be transferred can be identified; (c) payment terms for the goods or services to be transferred can be identified; (d) the contract has commercial substance and (e) collectability of substantially all of the consideration is probable. The Company recognizes revenue from products sold to a customer, including distributors, when it satisfies a performance obligation by transferring control over a product to the customer. The Company may also enter into several multi-annual capacity reservation and volume commitment arrangements with certain customers. These agreements constitute a binding commitment for the customers to purchase and for the Company to supply allocated commitment volumes in exchange for additional consideration. The consideration related to commitment fees is reported as revenues from sale of products as it is usually based on delivered quantities.

In certain circumstances, the Company may enter into agreements that concern principally revenues from services, where the performance obligation is satisfied over time. The objective when allocating the transaction price is to allocate the transaction price to each performance obligation (or distinct good or service) in an amount that depicts the amount of consideration to which the Company expects to be entitled in exchange for transferring the promised goods or services to the customer. The payment terms typically range between 30 to 90 days. Certain customers require the Company to hold inventory as consignment in their hubs and only purchase inventory when they require it. Revenue for sales of such inventory is recognized when, at the customer’s option, the products are withdrawn from the consignment and the Company satisfies a performance obligation by transferring control over a product to the customer.

Consistent with standard business practice in the semiconductor industry, price protection is granted to distribution customers on their existing inventory of the Company’s products to compensate them for changes in market prices. The Company accrues a provision for price protection based on a rolling historical price trend computed monthly as a percentage of gross distributor sales. This historical price trend represents differences in recent months between the invoiced price and the final price to the distributor, adjusted to accommodate a significant change in the selling price. The short outstanding inventory time, visibility into the inventory product pricing and long distributor pricing history have enabled the Company to reliably estimate price protection provisions at period-end. The Company records the accrued amounts as a deduction of “Net sales” in the consolidated statements of income at the time of the sale.

The Company’s customers occasionally return the Company’s products for technical reasons. The Company’s standard terms and conditions of sale provide that if the Company determines that products do not conform, the Company will repair or replace the non-conforming products, or issue a credit note or rebate of the purchase price. Quality returns are identified shortly after sale in customer quality control testing. The Company records the accrued amounts as a deduction of “Net sales” in the consolidated statements of income, using contractual and historical information.

The Company records a provision for warranty costs as a charge against “Cost of sales” in the consolidated statements of income, based on historical trends of warranty costs incurred as a percentage of sales, which management has determined to be a reasonable estimate of the probable losses to be incurred for warranty claims in a period. Any potential warranty claims are subject to the Company’s determination that the Company is at fault for damages, and such claims must usually be submitted within a short period of time following the date of sale. This warranty is given in lieu of all other warranties, conditions or terms expressed or implied by statute or common law. The Company’s contractual terms and conditions typically limit its liability to the sales value of the products which gave rise to the claims.

The Company’s insurance policy relating to product liability covers third-party physical damages and bodily injury, indirect financial damages as well as immaterial non-consequential damages caused by defective products.

In addition to product sales, the Company enters into arrangements with customers consisting in transferring licenses or related to license services. The revenue generated from these arrangements are reported on the line “Other revenues” of the consolidated statements of income.

2.18     Public funding

The Company receives funding from several governmental agencies and income is recognized when all contractual conditions for receipt of these funds are fulfilled and eligible expenditures incurred. Such funding is generally provided to encourage research, development and other innovation activities, industrialization deployment and local economic development. The conditions to receive government funding may include eligibility restrictions, approval by the local governmental authorities, annual budget appropriations, compliance with regulations, as well as specifications regarding objectives and results. Certain specific contracts include obligations to maintain a minimum level of employment and investment during a certain period. There could be penalties if these objectives are not fulfilled. Other contracts contain penalties for breach of contract, which may result in repayment obligations. Funding related to these contracts is recorded when the conditions required by the contracts are met. The Company’s funding programs are classified under two general categories: funding for research, development and other innovative activities, and capital investments.

Funding for research, development and innovative activities is the most common form of funding that the Company receives. This public funding is recorded as “Other income and expenses, net” in the consolidated statements of income. The funding is recognized ratably as the related costs are incurred once the agreement with the respective governmental agency has been signed and all applicable conditions are met. Other government assistance, such as funding received for industrialization deployment and local economic development in certain regions, are reported as a deduction of cost of sales or other operating expenses according to the nature of the underlying costs eligible to the grants.

French research tax credits (“Crédit Impôt Recherche”) and Italian research tax credits (“Credito d’Imposta Ricerca & Sviluppo”) are deemed to be grants in substance. The French research tax credits are to be paid in cash by the taxing authorities within three years in case they are not deducted from income tax payable during

this period of time. The Italian tax credits are compensated against payroll-related social charges. French and Italian tax credits are reported as a reduction of “Research and development expenses” in the consolidated statements of income.

Capital investment funding is recorded as a reduction of “Property, plant and equipment, net” on the consolidated balance sheets when the Company has incurred the eligible capital expenditures and when all conditions for eligibility have been fulfilled. Advances from capital grants received on capital investments that have not been incurred yet are reported as in the line "Other long-term liabilities" on the consolidated balance sheets. Capital investment funding is recognized in the Company’s consolidated statements of income by offsetting the depreciation charges of the funded assets during their useful lives. The Company also receives funding, which can be recovered through the reduction of various governmental liabilities, including income tax, value-added tax and employee-related social charges.

Funding receivables are reported as non-current assets unless cash settlement features of the receivables evidence that collection is expected within one year. Long-term receivables that do not present any tax attribute or legal restriction are reflected in the consolidated balance sheets at their net present value when the discounting effect is deemed to be significant.

2.19     Research and development

Research and development expenses include costs incurred by the Company, the Company’s share of costs incurred by other research and development interest groups, and costs associated with co-development contracts. Research and development expenses do not include marketing design center costs, which are accounted for as “Selling, general and administrative expenses” in the consolidated statements of income and process engineering, pre-production or process transfer costs which are recorded as “Cost of sales” in the consolidated statements of income. Research and development costs are expensed as incurred. The amortization expense recognized on technologies and licenses purchased by the Company from third parties to facilitate the Company’s research and development activities is reported as “Research and development expenses” in the consolidated statements of income.

2.20     Advertising costs

Advertising costs are expensed as incurred and are recorded as “Selling, general and administrative expenses” in the consolidated statements of income. Advertising expenses for 2023, 2022 and 2021 were $23 million, $18 million and $12 million, respectively.

2.21     Start-up and phase-out costs

Start-up costs represent costs incurred in the ramp-up phase of the Company's newly integrated manufacturing facilities. The costs of phase-outs are associated with the latest stages of facilities closure when the relevant production volumes become immaterial. Start-up costs and phase-out costs are included in the line “Other income and expenses, net” of the consolidated statements of income.

2.22     Investments in equity securities

Investments in equity securities that have readily determinable fair values and for which the Company does not have the ability to exercise significant influence are classified as equity securities measured at fair value through earnings. Changes in the fair value of these securities are reported in the consolidated statements of income within “Other income and expenses, net” when these instruments are held within the Company’s operating activities. Gains and losses arising from changes in the fair value of securities not related to operating activities are presented in the consolidated statements of income as non-operating elements within “Gain (loss) on financial instruments, net” in the period in which they arise. The fair values of quoted equity securities are based on current market prices. If the market for a financial asset is not active or if no observable market price is obtainable, the Company measures fair value by using assumptions and estimates. In measuring fair value, the Company makes maximum use of market inputs and minimizes the use of unobservable inputs.

For investments in equity securities without readily determinable fair values and for which the Company does not have the ability to exercise significant influence, the Company has elected to apply the cost method as a measurement alternative. Under the cost method of accounting, investments are carried at historical cost, less impairment. An impairment loss is recorded when there are identified events or changes in circumstances that may have a significant adverse effect on the value of the investment. Loss is immediately recorded in the consolidated statements of income on the line “Gain (loss) on financial instruments, net” and is based on the Company’s assessment of any significant and sustained reductions in the investment’s value. Gains and losses on investments sold are determined on the specific identification method and are recorded as non-operating element in the line “Gain (loss) on financial instruments, net” of the consolidated statements of income when the transaction is not related to operating activities.

The Company did not hold any material equity securities as of December 31, 2023 and December 31, 2022.

2.23     Investments in debt securities

Debt securities are included in current assets when they represent investments of funds available for current operations.

Changes in fair value of debt securities classified as available-for-sale are recognized as a component of “Other comprehensive income (loss)” in the consolidated statements of comprehensive income. The Company assesses at each balance sheet date whether there is objective evidence that a debt security or group of debt securities is impaired. An unrealized impairment loss exists when the fair value of the instrument declines below its amortized cost basis. An impairment loss is recognized in earnings, through a direct reduction of the value of the asset, when the Company intends to sell the debt security or when it is more likely than not that the Company will be required to sell the instrument before recovery of the amortized cost basis. Moreover, an impairment loss is recognized in earnings through a credit loss allowance for any portion of the unrealized impairment loss resulting from a credit loss. Impairment losses recognized in the consolidated statements of income are not reversed through earnings.

The fair values of quoted debt securities are based on current market prices. If the market for a financial asset is not active and if no observable market price is obtainable, the Company measures fair value by using assumptions and estimates. In measuring fair value, the Company makes maximum use of market inputs and minimizes the use of unobservable inputs.

The Company did not hold any debt securities classified as held-to-maturity or for which the Company would have elected to apply the fair value option.

2.24     Derivative financial instruments and hedging activities

Derivative financial instruments are initially recognized on the date a derivative contract is entered into and are subsequently measured at fair value. The method of recognizing the gain or loss resulting from the derivative instrument depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the hedge transaction. The Company has designated certain derivatives as hedges of a particular risk associated with a highly probable forecasted transaction (cash flow hedge).

The Company documents, at inception of the transaction, the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedging transactions. The Company also documents its assessment, both at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items. Derivative instruments that are not designated as hedges are measured at fair value through earnings.

Cash Flow Hedge

As part of its ongoing operating, investing and financing activities, the Company enters into certain derivative transactions that may be designated and may qualify as hedging instruments. To reduce its exposure to U.S. dollar exchange rate fluctuations, the Company hedges certain Euro-denominated forecasted transactions that cover at reporting date a large part of its research and development, and selling, general and administrative expenses as well as a portion of its front-end manufacturing costs of semi-finished goods within cost of sales

through the use of currency forward contracts and currency options, including collars. The Company also hedges through the use of currency forward contracts certain Singapore dollar-denominated manufacturing forecasted transactions.

The derivative instruments are designated and qualify for cash flow hedge at inception of the contract and on an ongoing basis over the duration of the hedge relationship. They are reflected at their fair value as “Other current assets” or “Other payables and accrued liabilities” in the consolidated balance sheets when settlement is expected to occur within twelve months after the reporting date. They are reported as "Other non-current assets" or "Other long-term liabilities" in the consolidated balance sheets when settlement is expected beyond twelve months. The criteria for designating a derivative as a hedge include the instrument’s effectiveness in risk reduction and matching of the derivative instrument to its underlying transactions with the critical terms of the hedging instrument matching the terms of the hedged forecasted transaction. This enables the Company to conclude that changes in cash flows attributable to the risk being hedged are expected to be substantially offset by the hedging instruments.

For derivative instruments designated as cash flow hedge, the change in fair value for the effective portion of the hedge is reported as a component of “Other comprehensive income (loss)” in the consolidated statements of comprehensive income and is reclassified into earnings in the same period in which the hedged transaction affects earnings, and within the same consolidated statements of income line as the hedged transaction. For these derivatives, ineffectiveness appears if the cumulative gain or loss on the derivative hedging instrument exceeds the cumulative change in the expected future cash flows on the hedged transaction. Effectiveness on transactions hedged through purchased options is measured on the full fair value of the option, including time value.

Derivative financial instruments not designated as a hedge

The Company conducts its business on a global basis in various major international currencies. As a result, the Company is exposed to adverse movements in foreign currency exchange rates. The Company enters into foreign currency forward contracts and currency options to reduce its exposure to changes in exchange rates and the associated risk arising from the denomination of certain assets and liabilities in foreign currencies at the Company's subsidiaries.

Financial instruments not designated as a hedge are classified as current assets when they are expected to be realized within twelve months of the balance sheet date. Marked-to-market gains or losses arising from changes in the fair value of these instruments are reported in the consolidated statements of income within “Other income and expenses, net” in the period in which they arise, since the transactions for these instruments occur within the Company’s operating activities.

2.25     Recent accounting pronouncements

(a)Accounting pronouncements effective in 2023

No new guidance was adopted in 2023 with a significant impact on the Company's financial statements, financial positions and operations.

(b)Accounting pronouncements expected to impact the Company’s operations that are not yet effective and have not been early adopted by the Company

In November 2023, the FASB issued new guidance related to segment reporting, which requires incremental disclosures about reportable segments, without changing though the definition of a segment or the guidance for determining reportable segments. The new guidance requires disclosures of significant segment expenses that are (i) regularly provided to (or easily computed from information regularly provided to) the chief operating decision maker ("CODM"); (ii) included in the reported measure of segment profit or loss. The new guidance also requires that an entity discloses, on an annual and interim basis, an amount for "other segment items" by reportable segment, and a description of its composition. Moreover, annual disclosures about a reportable segment's profit or loss and assets become mandatory on interim periods. Finally, the title and position of the CODM, together with an explanation of how the CODM uses the reported measures of segment profit or loss in assessing segment performance and deciding how to allocate resources, are also required. The guidance is effective for the Company's 2024 annual reporting and 2025 interim periods. The guidance will be applied retrospectively, with early adoption permitted. The Company will adopt the new guidance when effective and is currently assessing the impact the new guidance will have on its segment reporting.

In December 2023, the FASB issued new guidance related to income taxes, which requires additional disclosures, primarily around disaggregation of income tax paid and specific categories in the income tax rate reconciliation. The guidance is effective for the year ended December 31, 2025, with early adoption permitted. The guidance will be applied prospectively. Retrospective application is permitted. The Company is currently assessing the impact the new guidance will have on its annual income tax disclosures.

*    Other Comprehensive Income

In 2023, the Company invested $1,653 million available cash in U.S. Treasury bonds. The debt securities have an average rating of Aaa/AA+/AA+ from Moody’s, S&P and Fitch, respectively, with a weighted average maturity of 1.6 years. The debt securities are reported as current assets on the line “Marketable securities” on the consolidated balance sheet, since they represent investments of funds available for current operations. The Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of the amortized cost basis. The bonds are classified as available-for-sale financial assets and recorded at fair value as of December 31, 2023. The fair value measurement corresponds to a Level 1 fair value hierarchy measurement. The aggregate amortized cost basis of these securities totaled $1,645 million as of December 31, 2023.

Marketable securities totaling $750 million at principal amount were transferred to financial institutions as part of short-term securities lending transactions, in compliance with corporate policies. The Company, acting as the securities lender, does not hold any collateral in this unsecured securities lending transaction. The Company retains effective control on the transferred securities.

As of December 31, 2022, the Company held $679 million in marketable securities classified as available-for-sale debt securities. 

The below table details debt securities that were in an unrealized loss position as of December 31, 2023:

	December 31, 2023
	Less than 12 months		More than 12 months		Total

Receivables [Abstract]

Trade Accounts Receivable, Net

TRADE ACCOUNTS RECEIVABLE, NET

Trade accounts receivable, net consist of the following:

	December 31,	December 31,
	2023	2022
Trade accounts receivable	1,750	1,991
Current expected credit losses allowance ("CECLA")	(19)	(21)
Total	1,731	1,970

The Company uses a lifetime expected losses allowance for all trade receivables based on failure rates, as applied to the gross amounts of trade accounts receivable. The allowance also includes reasonable assumptions about future credit trends. The historical loss rates are adjusted to reflect current and forward-looking information on macro-economic factors affecting the ability of the Company’s customers to settle the receivables. In addition to the factors already embedded in the failure rates, as applied on trade accounts receivable, the Company has identified cyclicality and uncertainties around continued growth for the semiconductor industry and its serviceable available market to be the most relevant factors. These macro-economic factors are weighted into different economic scenarios, in line with estimates and methodologies applied by other business entities, including financial institutions.

On that basis, the changes in reported CECLA for the year ended December 31, 2023 are presented below:

CECLA As of December 31, 2022	(21)
Current-period adjustment to CECLA	2
CECLA As of December 31, 2023	(19)

Adjustments to the expected credit losses allowance are reported in the line “Selling, general and administrative expenses” in the consolidated statements of income.

There were no significant write-offs in 2023, 2022 and 2021.

Derivative instruments	58	56
Other current assets	128	61
Total	1,295	734

Public funding receivables are described in Note 7.

Taxes and other government receivables mainly include receivables related to value-added tax, primarily in European tax jurisdictions.

Advances and prepayments include prepaid amounts associated with multi-annual supply and service agreements.

Derivative instruments are further described in Note 26.

Other current assets include a $28 million contribution to be received in 2024 from a third party as part of a collaborative agreement associated with the ongoing capacity expansion project for the 300mm wafer fab in Crolles, France. Total contributions received from the third party as part of this collaborative agreement totaled $54 million, reported as "Proceeds from capital grants and other contributions" in the statement of cash flows for the year ended December 31, 2023.

The Company applies a current expected credit losses model on all financial assets measured at amortized cost, including deposits, loans and receivables. The major portion of other current assets to which this model applies corresponds to government receivables. Due to the existing history of zero-default on receivables originated by governments, the expected credit losses are assumed to be not significant as of December 31, 2023 and December 31, 2022. Other current assets presented in the table above within the lines “Loans and deposits” and “Other current assets” are composed of amounts not deemed at exposure of default. Consequently, no loss allowance was reported on those current assets as of December 31, 2023 and December 31, 2022.

Long-term investments	22	11
Total	22	11

Long-term investments are equity securities with no readily determinable fair value for which the Company has elected to apply the cost method as a measurement alternative. Long-term investments include a $9 million interest in DNP Photomask Europe S.p.A (“DNP”). In 2023, the Company paid $10 million to acquire a minor

equity stake in a start up. The investment is related to the development of Silicon Photonics technology for the RF Communications business.

In 2023, the Company and Sanan Optoelectronics jointly created SANAN, STMicroelectronics Co., Ltd. for high-volume 200mm SiC device manufacturing activities in China. The purpose of the joint venture is to support the rising demand for the Company's SiC devices for car electrification and industrial power and energy applications in China. With the creation and future operations of SST JV, the Company seeks to create a fully integrated vertical value chain aiming at serving the Chinese electrification market. Sanan Optoelectronics will build a separate 200mm SiC substrate manufacturing facility to fulfill SST JV's needs. SST JV will produce SiC devices exclusively for the Company, using the Company's proprietary SiC manufacturing process technology and know how and serving as a dedicated foundry to support the Company's demand for Chinese customers.

The Company has identified SST JV as a VIE, primarily based on the disproportionality between its 49% equity interest rights and its economic interest and operating role in the joint venture. Indeed the significant activities of SST JV involve or are conducted on behalf of the Company as the sole customer of the joint venture. Moreover, through its key role in the successful process qualification and future manufacturing efficiency based on its SiC manufacturing process technology, the Company has the power to control the activities that most significantly impact SST JV's future economic performance. Additionally, based on the nature of the risks impacting SST JV's future economic performance, the Company will absorb the potential losses of SST JV or the right to receive benefits downstream the whole integrated SiC device value chain. Consequently, the Company has a controlling financing interest in SST JV and is the primary beneficiary of the VIE.

As the primary beneficiary of SST JV, the Company fully consolidates the VIE, with the recognition of 51% non-controlling interest. Non-controlling interest amounted to $52 million as of December 31, 2023, which corresponds to the capital contribution received from Sanan Optoelectronics upon creation and first consolidation of SST JV. No gain or loss was recognized on the initial consolidation of the VIE as no fair value measurement was required, the joint venture being a newly incorporated entity. Profit and loss reported by the VIE for the year ended December 31, 2023 was not material. The carrying amount of SST JV's assets and liabilities, together with their classification in the consolidated balance sheet as of December 31, 2023, are separately disclosed in Note 7, Note 10 and Note 17.

The joint venture agreement signed between Sanan Optoelectronics and the Company includes further capital subscriptions of both shareholders on a proportional equity interest basis. The total amount for the full build out of the joint venture will also be financed by local government support, as disclosed in Note 7, and loans to the joint venture.

Public funding receivables, including French research tax credit receivable, are described in Note 7.

Prepayments and deposits to third parties include receivables related to long-term supply agreements involving purchase of raw materials, capacity commitments, cloud-hosting arrangements, and other services.

In 2023 and 2022, the Company entered into factoring transactions to accelerate the realization in cash of certain long-term receivables. The Company sold without recourse $118 million and $110 million of these receivables in the years ended December 31, 2023 and 2022 respectively, with a financial cost of $5 million and $1 million respectively.

The major portion of other non-current assets to which the expected credit loss model applies are long-term State receivables. Due to the existing history of zero-default on receivables originated by governments, the expected credit losses are assumed to be negligible as of December 31, 2023 and December 31, 2022. Other non-current assets presented in the table above on the line “Other non-current assets” are composed of individually not significant amounts not deemed to have exposure of default. Consequently, no significant expected credit loss allowance was reported on other non-current assets at reporting date.

U.S. dollar	1,496	1,495
Euro	1,431	1,222
Total	2,927	2,717

On August 4, 2020, the Company issued a $1.5 billion principal amount of dual tranche senior unsecured convertible bonds (Tranche A and Tranche B for $750 million each tranche), due 2025 and 2027, respectively. Tranche A bonds were issued at 105.8% as zero-coupon bonds while Tranche B bonds were issued at 104.5% as zero-coupon bonds. The conversion price at issuance was $43.62 for Tranche A equivalent to a 47.5% conversion premium and $45.10 for Tranche B, equivalent to a 52.5% conversion premium. These conversion features correspond to an equivalent of 4,585 shares per each Tranche A bond $200,000 par value and an equivalent of 4,435 shares per each Tranche B bond $200,000 par value. The bonds are convertible by the bondholders or are callable by the issuer upon certain conditions, on a net-share settlement basis, except if the

issuer elects a full-cash or full-share conversion as an alternative settlement. The net proceeds from the bond offering were $1,567 million, after deducting issuance costs paid by the Company.

As per contractual terms, the bondholders have full conversion rights on Tranche A bonds, starting August 2023. In terms of Tranche B, up until August 2024, the bonds can be converted by the bondholders with a contingent feature of 130% of the conversion price, measured at quarter-end for the following quarter. After that date, the bondholders will have full conversion rights.

As per contractual terms, starting August 2023, Tranche A bonds are callable by the Company with a 130% contingent feature, with the exercise of its call rights being preceded by the release, by the Company, of an Optional Redemption Notice. The same feature applies for Tranche B bonds but only after August 2024.

As of December 31, 2023, the Company stock price exceeded the conversion price of the senior unsecured convertible bonds. However, the 130% stock price contingent feature was not met. Consequently, Tranche A bonds are not callable by the Company and bondholders cannot exercise their conversion rights on Tranche B bonds.

The convertible debt was reported as Long-term debt in the consolidated balance sheets as of December 31, 2023 and December 31, 2022, based on its original maturity, after having considered several factors, such as the uncertainty around the timing of the potential exercise of the conversion rights by bondholders and the call rights by the Company.

Aggregate future maturities of total long-term debt (including current portion) at principal amount are as follows:

	December 31,
	2023
2024	217
2025	962
2026	212
2027	947
2028	198
Thereafter	395
Total	2,931

The difference between the total aggregated future maturities in the preceding table and the total carrying amount of long-term debt is due to unamortized issuance costs on the dual tranche senior unsecured convertible bonds.

Credit facilities

The Company’s long-term debt contained standard conditions but does not impose minimum financial ratios. The Company had unutilized committed medium-term credit facilities with core relationship banks totalling $1,030 million as of December 31, 2023.

The EIB Loans are comprised of three long-term amortizing credit facilities as part of R&D funding programs. The first one, signed in August 2017, is a €500 million loan in relation to R&D and capital expenditures in the European Union for the years 2017 and 2018. The entire amount was fully drawn in Euros corresponding to $303 million outstanding as of December 31, 2023. The second one, signed in 2020, is a €500 million credit facility agreement with EIB to support R&D and capital expenditure programs in Italy and France. The amount was fully drawn in Euros representing $442 million outstanding as of December 31, 2023. In 2022, the Company signed a third long-term amortizing credit facility with EIB of €600 million, out of which, €300 million was withdrawn representing $332 million outstanding as of December 31, 2023. In January 2024, an amount of $300 million was withdrawn under this credit facility.

The actuarial losses incurred in 2023 were primarily due to a decrease in discount rates applied against future expected benefit payments and resulted in an increase of the benefit obligation mainly for the plans located in the United States, France and Switzerland. The actuarial gains incurred in 2022 were primarily due to an increase in discount rates applied against future expected benefit payments and resulted in a decrease of the benefit obligation mainly for the plans located in France, in the United States and Switzerland.

Actual return on plan assets reflect changes in market conditions during each reporting year.

The components of accumulated other comprehensive loss (income) before tax effects were as follows:

For pension plans with projected benefit obligations in excess of plan assets, the benefit obligation and fair value of plan assets were $950 million and $478 million, respectively, as of December 31, 2023 and $839 million and $427 million, respectively, as of December 31, 2022.

The components of the net periodic benefit cost included the following:

	Pension Benefits			Other Long-term Benefits
	Year ended December 31, 2023	Year ended December 31, 2022	Year ended December 31, 2021	Year ended December 31, 2023	Year ended December 31, 2022	Year ended December 31, 2021

Pension benefits components other than service cost, recognized outside of operating income in “Other components of pension benefit costs” in the Company’s consolidated statements of income, were $19 million, $11 million and $10 million in the years ended December 31, 2023, 2022 and 2021, respectively.

The weighted average assumptions used to determine the benefit obligation and the periodic benefit costs for pension plans and other long-term benefits were as follows:

	2023		2022		2021
Benefit obligation
Discount rate	3.73	%	4.18	%	1.84	%
Salary increase rate	2.17	%	2.31	%	2.27	%
Net periodic benefit cost
Discount rate	4.18	%	1.84	%	1.45	%
Salary increase rate	2.31	%	2.27	%	2.43	%
Expected long-term rates of return on plan assets	2.66	%	3.19	%	3.44	%

The discount rate was determined by reference to market yields on high quality long-term corporate bonds applicable to the respective country of each plan, with terms consistent with the terms of the benefit obligations. In developing the expected long-term rate of return on assets, the Company modelled the expected long-term rates of return for broad categories of investments held by the plan against a number of various potential economic scenarios.

The Company’s pension plan asset allocation as of December 31, 2023 and December 31, 2022 is as follows:

	Percentage of Plan Assets at December
Asset Category	2023		2022
Cash and cash equivalents	1	%	1	%
Equity securities	13	%	17	%
Government debt securities	11	%	10	%
Corporate debt securities	19	%	21	%
Investments in funds(a)	15	%	16	%
Real estate	1	%	1	%
Other (mainly insurance assets – contracts and    reserves)	40	%	34	%
Total	100	%	100	%

(a)     As of December 31, 2023, investments in funds were composed of commingled and multi-strategy funds invested in diversified portfolios of fixed income (68%) - mainly corporate bonds, equities (24%), time deposits and money market (5%) and other instruments (3%). As of December 31, 2022, investments in funds were composed of commingled and multi-strategy funds invested in diversified portfolios of fixed income (79%) - mainly corporate bonds, time deposits and money market (11%) and other instruments (10%).

As of December 31, 2023, the Company’s plan asset allocation was in line with the targets set for each plan.

The Company’s detailed pension plan asset allocation including the fair-value measurements of those plan assets as of December 31, 2023 is as follows:

The majority of insurance contract plan assets relate to pension plans for the Company's employees in Switzerland. Those plans are provided by collective pension foundations and contributions are invested in fully insured assets that provide a guaranteed contractual return. As such, the fair value of such assets equals to the employees' accrued savings and calculated using total employer and employee contributions plus any accumulated interest credited, which is substantially equivalent to the related cash surrender value. The approach is consistent with prior years.

For plan assets measured at fair value using significant unobservable inputs (Level 3), the reconciliation between January 1, 2023 and December 31, 2023 is presented as follows:

	Fair Value Measurements using Significant Unobservable Inputs (Level 3)

The Company’s investment strategy for its pension plans is to optimize the long-term investment return on plan assets in relation to the liability structure to maintain an acceptable level of risk while minimizing the cost of providing pension benefits and maintaining adequate funding levels in accordance with applicable rules in each jurisdiction. The Company’s practice is to periodically conduct a review of its asset allocation strategy, in such a way that the asset allocation is in line with the targeted asset allocation within reasonable boundaries. The

Company’s asset portfolios are managed in such a way as to achieve appropriate diversification in line with the asset allocation strategy. The Company does not manage any assets internally.

After considering the funded status of the Company’s defined benefit plans, movements in the discount rate, investment performance and related tax consequences, the Company may choose to make contributions to its pension plans in any given year in excess of required amounts. The Company’s contributions to plan assets were $26 million in 2023 and $25 million in 2022 and the Company expects to contribute $27 million to plan assets in 2024.

The Company’s estimated future benefit payments as of December 31, 2023 are as follows:

Years	Pension Benefits	Other Long-term Benefits
2024	59	7
2025	63	8
2026	86	8
2027	54	9
2028	60	8
From 2029 to 2033	375	44

The Company has certain defined contribution plans, which accrue benefits for employees on a pro-rata basis during their employment period based on their individual salaries. The Company’s accrued benefits related to defined contribution pension plans for $27 million as of December 31, 2023 and $24 million as of December 31, 2022. The annual cost of these plans amounted to approximately $114 million in 2023, $100 million in 2022 and $101 million in 2021.

Equity [Abstract]

Shareholders' Equity

SHAREHOLDERS’ EQUITY

18.1     Outstanding shares

The authorized share capital of the Company is Euro 1,810 million, consisting of 1,200,000,000 common shares and 540,000,000 preference shares, each with a nominal value of €1.04. As of December 31, 2023, the number of shares of common stock issued was 911,281,920 shares (911,281,920 as of December 31, 2022).

As of December 31, 2023, the number of shares of common stock outstanding was 902,771,081, 903,865,763 as of December 31, 2022 and 906,518,057 as of December 31, 2021.

18.2     Preference shares

The 540,000,000 preference shares, when issued, will entitle a holder to full voting rights and to a preferential right to dividends and distributions upon liquidation.

The Company is a party to an option agreement regarding the preference shares with Stichting Continuïteit ST (the “Stichting”), entered into on January 22, 2007, with a duration of ten years, an agreement which was extended for another ten years in October 2016. The Managing Board and Supervisory Board, along with the board of the Stichting, have declared that they are jointly of the opinion that the Stichting is independent of the Company. The option agreement provides for the issuance of up to a maximum 540,000,000 preference shares. Any such shares would be issued to the Stichting upon its request and in its sole discretion and upon payment of at least 25% of the par value of the preference shares to be issued. The shares would be issuable in the event of actions which the board of the Stichting determines would be contrary to the Company’s interests, shareholders and other stakeholders and which, in the event of a creeping acquisition or offer for the Company’s common shares, are not supported by the Company’s Managing Board and Supervisory Board. The preference shares may remain outstanding for no longer than two years. The effect of the preference shares may be to deter potential acquirers from effecting an unsolicited acquisition resulting in a change of control as well as to create a level-playing field in the event actions which are considered to be hostile by the Company’s Managing Board and Supervisory Board, as described above, occur and which the board of the Stichting determines to be contrary to the Company’s interests, shareholders and other stakeholders.

There were no preference shares issued as of December 31, 2023 and December 31, 2022.

18.3     Treasury stock

As of December 31, 2023, the Company owned 8,510,839 shares classified as treasury stock in the consolidated statement of equity compared to 7,416,157 shares as of December 31, 2022 and 4,758,863 shares as of December 31, 2021.

The treasury shares have been originally designated for allocation under the Company’s share-based remuneration programs. As of December 31, 2023, 81,022,515 of these treasury shares were transferred to employees under the Company’s share-based remuneration programs, of which 6,502,300 during the year ended December 31, 2023, 6,587,002 shares during the year ended December 31, 2022 and 7,448,615 shares during the year ended December 31, 2021.

On July 1, 2021, the Company announced the launch of a share buy-back program of up to $1,040 million to be executed within a three-year period. During 2023, the Company purchased approximately 7.6 million shares of its outstanding common stock for $346 million as part of the program. The Company purchased approximately

9.2 million shares of its outstanding common stock for $346 million during 2022. The Company purchased approximately 3.9 million shares of its outstanding common stock for $172 million during 2021.

18.4     Unvested share awards for the Supervisory Board

On an annual basis and until the year 2012, the Compensation Committee (on behalf of the Supervisory Board and with its approval) used to grant stock-based awards (options to acquire common shares of the Company) to the members and professionals of the Supervisory Board (“The Supervisory Board Plan”). The awards were granted at the nominal value of the share of €1.04 (exercise price of the option). The options granted under the Supervisory Board Plan vested and became exercisable immediately, while the shares resulting from these awards vested and therefore became available for trade evenly over three years (one third every year), with no market, performance or service conditions.

At the Company’s AGM held on June 21, 2013, it was resolved to abolish and terminate the stock-based compensation for the Supervisory Board members and professionals.

The table below summarizes grants under the outstanding stock award plans, as authorized by the Compensation Committee:

Year of grant	Options granted	Options waived at grant
2011	172,500	(30,000)
2012	180,000	(22,500)

18.5     Unvested share awards for the employees

On an annual basis, the Compensation Committee (on behalf of the Supervisory Board and with its approval) grants stock-based awards to the senior executives and selected employees (the “Employee Plan”). The awards are granted for services rendered under the Employee Plan. There are two types of unvested shares: (1) shares granted to employees, which are subject only to service conditions and vest over the requisite service period, and (2) shares granted to senior executives, for which vesting is subject to performance conditions.

For plan 2020, the performance conditions consisted of two external targets (sales evolution and operating income compared to a basket of competitors) weighting for two thirds of the total number of awards granted, and of one internal target (return on net assets compared to the previous period), weighting for one third of the total number of awards granted. For plans 2021, 2022 and 2023, the performance conditions consist of two external targets (sales evolution and operating income compared to a basket of competitors) weighting for two thirds of the total number of awards granted, and of one internal target (Company’s sustainability and diversity performance), weighting for one third of the total number of awards granted. Sustainability and diversity performance include environment/climate, diversity and inclusions indicators, ESG investor index and carbon rating.

Stock awards are subject to three-year cliff-vesting for the Company's CEO, while they vest over a grading three-year service period for other employees (32% as of the first anniversary of the grant, 32% as of the second anniversary of the grant and 36% as of the third anniversary of the grant). Applicable only to the 2023 plan,

stock awards allocated to members of the Executive Committee are also subject to three-year cliff vesting. In addition, for the year 2020, a Special Bonus was granted to the Company’s CEO.

The table below summarizes grants outstanding during the year 2023, as authorized by the Compensation Committee:

Date of grant	Plan name	Number of shares granted	Number of shares waived	Number of shares lost on performance conditions

(*)    As of the date of issuance of these consolidated financial statements, a final decision by the Compensation Committee of the Supervisory Board on the achievement of the performance conditions had not been made yet.

A summary of the unvested share activity by plan for the year ended December 31, 2023 is presented below:

Unvested Shares	Unvested as at December 31, 2022	Granted	Forfeited / waived	Cancelled on failed vesting conditions	Vested	Unvested as at December 31, 2023
2020 CEO Special Bonus	5,334	—	—	—	(5,334)	—
2020 Employee Plan	2,780,796	—	(11,851)	—	(2,768,945)	—
2021 Employee Plan	3,699,514	—	(32,571)	—	(1,716,700)	1,950,243
2022 Employee Plan	6,496,525	—	(80,065)	—	(2,065,721)	4,350,739
2023 Employee Plan	—	5,449,135	(28,730)	—	—	5,420,405
Total	12,982,169	5,449,135	(153,217)	—	(6,556,700)	11,721,387

The grant date fair value of unvested shares granted to the CEO under the 2020 CEO Special Bonus Plan was $26.64, which was based on the market price of the shares at the date of the grant.  

The grant date weighted average fair value of unvested shares granted to employees under the 2020 Employee Plan was $30.17. On March 24, 2021, the Compensation Committee approved the statement that with respect to the shares subject to performance conditions, all three performance conditions were fully met. Consequently, the compensation expense recorded on the 2020 Employee Plan reflects the statement that – for the portion of shares subject to performance conditions – 100% of the awards granted has fully vested, as far as the service condition was met.

The grant date weighted average fair value of unvested shares granted to employees under the 2021 Employee Plan was $39.20. On March 23, 2022, the Compensation Committee approved the statement that with respect to the shares subject to performance conditions, two performance conditions were fully met. Consequently, the compensation expense recorded on the 2021 Employee Plan reflects the statement that – for the portion of shares subject to performance conditions – two thirds of the awards granted will fully vest, as far as the service condition is met.

The grant date weighted average fair value of unvested shares granted to employees under the 2022 Employee Plan was $35.92. On March 22, 2023, the Compensation Committee approved the statement that with respect to

the shares subject to performance conditions, all three performance conditions were fully met. Consequently, the compensation expense recorded on the 2022 Employee Plan reflects the statement that – for the portion of shares subject to performance conditions – 100% of the awards granted will fully vest, as far as the service condition is met.

The grant date weighted average fair value of unvested shares granted to employees under the 2023 Employee Plan was $50.96. Moreover, for the portion of the shares subject to performance conditions (2,589,952 shares) the Company estimated the number of awards expected to vest by assessing the probability of achieving the performance conditions. As of the date of issuance of these consolidated financial statements, a final determination by the Compensation Committee of the Supervisory Board of the achievement of the performance conditions had not been made yet. The Company estimated that 100% of the awards subject to performance conditions are expected to vest. Consequently, the compensation expense recorded for the 2023 Employee Plan reflects the expected vesting of 100% of the awards granted with performance conditions, subject to the service condition being met. The assumption of the expected number of awards to be vested upon achievement of the performance conditions is subject to changes based on the final measurement of the conditions, which is expected to occur in the first half of 2024.

The following table illustrates the classification of pre-payroll tax and social contribution stock-based compensation expense included in the consolidated statements of income for the years ended December 31, 2023, 2022 and 2021:

	December 31, 2023	December 31, 2022	December 31, 2021

R&D	71	69	70
SG&A	125	112	117
Total pre-payroll tax and social contribution    compensation	236	215	221

The grant date fair value of the shares that vested in 2023 was $226 million compared to $189 million in 2022 and $181 million in 2021.

Stock-based compensation, excluding payroll tax and social contribution, capitalized as part of inventory was $13 million as of December 31, 2023, compared to $11 million as of December 31, 2022 and $9 million as of December 31, 2021. As of December 31, 2023, there was $265 million of total unrecognized compensation cost related to the grant of unvested shares, which is expected to be recognized over a weighted average period of approximately 10 months.

The total deferred income tax benefit recognized in the consolidated statements of income related to unvested share-based compensation expense amounted to $17 million, $15 million and $14 million for the years ended December 31, 2023, 2022 and 2021, respectively.

Revenue from Contract with Customer [Abstract]

Revenues

REVENUES

19.1     Nature of goods and services

The Company designs, develops, manufactures and markets a broad range of products, including discrete and standard commodity components, application-specific integrated circuits (“ASICs”), full-custom devices and semi-custom devices and application specific standard products (“ASSPs”) for analog, digital and mixed-signal applications. In addition, the Company participates in the manufacturing value chain of smartcard products, which includes the production and sale of both silicon chips and smartcards.

The principal activities – separated by reportable segments – from which the Company generates its revenues are described in Note 20.

Other revenues consist of license revenue, service revenue related to transferring licenses, patent royalty income, sale of scrap materials and manufacturing by-products.

While the majority of the Company’s sales agreements contain standard terms and conditions, the Company may, from time to time, enter into agreements that contain multiple performance obligations or terms and conditions. Those agreements concern principally the revenues from services, where the performance obligation is satisfied over time. The objective when allocating the transaction price is to allocate the transaction price to each performance obligation (or distinct good or service) in an amount that depicts the amount of consideration to which the Company expects to be entitled in exchange for transferring the promised goods or services to the customer.

19.2     Revenue recognition and disaggregation

The Company recognizes revenue from products sold to a customer, including distributors, when it satisfies a performance obligation at a point in time by transferring control over a product to the customer. This usually occurs at the time of shipment. The performance obligations linked to the sale of goods contracts have the original expected length of less than one year. The transaction price is determined based on the contract terms, adjusted for price protection, if applicable. The revenues from services are usually linked to performance obligations transferred over time and are recognized in line with the contract terms.

In 2023 and 2022, the Company signed several multi-annual capacity reservation and volume commitment arrangements with certain customers. These agreements constitute a binding commitment for the customers to purchase and for the Company to supply allocated commitment volumes in exchange for additional consideration. The consideration related to commitment fees is reported as revenues from sale of products as it is usually based on delivered quantities. Advances from customers received as part of those agreements are described in Note 14 and Note 17.

The payment terms typically range between 30 to 90 days.

The Company’s consolidated net revenues disaggregated by reportable segment are presented in Note 20. The following tables present the Company’s consolidated net revenues disaggregated by geographical region of shipment, nature and market channel:

	Year ended
	December 31, 2023	December 31, 2022	December 31, 2021
Net revenues by geographical region of shipment(1)
EMEA	4,836	3,619	2,557
Americas	2,724	2,310	1,525
Asia Pacific	9,726	10,199	8,679
Total net revenues	17,286	16,128	12,761
Net revenues by nature
Revenues from sale of products	17,094	15,953	12,560
Revenues from sale of services	145	130	169

Distribution	5,818	5,364	4,275
Total net revenues	17,286	16,128	12,761

(1)Net revenues by geographical region of shipment are classified by location of customer invoiced or reclassified by shipment destination in line with customer demand. For example, products ordered by U.S.-based companies to be invoiced to Asia Pacific affiliates are classified as Asia Pacific revenues. Furthermore, the Company, among the different periods, may be affected by shifts in shipments from one location to another, as requested by customers.

(2)Original Equipment Manufacturers (“OEM”) are the end-customers to which the Company provides direct marketing application engineering support, while Distribution refers to the distributors and representatives that the Company engages to distribute its products around the world.

The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which the Company recognizes revenue at the amount to which the Company has the right to invoice for services performed.

In 2023, 2022 and 2021, the Company’s largest customer, Apple, represented 12.3%, 16.8% and 20.5% of consolidated net revenues, respectively, reported in the ADG, AMS and MDG segments.

Segment Information

SEGMENT INFORMATION

The Company designs, develops, manufactures and markets a broad range of products, including discrete and standard commodity components, ASICs, full custom devices and semi-custom devices and ASSPs for analog, digital, and mixed-signal applications. In addition, the Company further participates in the manufacturing value chain of smartcard products, which includes the production and sale of both silicon chips and smartcards.

As of December 31, 2023, the Company’s reportable segments were as follows:

•Automotive and Discrete Group (ADG), comprised of dedicated automotive integrated circuits (“ICs”), and discrete and power transistor products.

•Analog, MEMS and Sensors Group (AMS), comprised of analog, smart power, MEMS sensors and actuators, and optical sensing solutions.

•Microcontrollers and Digital ICs Group (MDG), comprised of general-purpose microcontrollers and microprocessors, connected security products (e.g. embedded secured elements and NFC readers), memories (e.g. serial and page EEPROM) and RF and Communications products.

Net revenues of “Others” include revenues from sales assembly services and other revenues. For the computation of the segments’ internal financial measurements, the Company uses certain internal rules of allocation for the costs not directly chargeable to the segments, including cost of sales, SG&A expenses and a part of R&D expenses. In compliance with the Company’s internal policies, certain costs are not allocated to the segments, but reported in “Others”. Those comprise unused capacity charges, including reduced manufacturing activity due to COVID-19 and incidents leading to power outage, impairment, restructuring charges and other related closure costs, management reorganization expenses, start-up and phase-out costs, and other unallocated

income (expenses) such as: strategic or special R&D programs, certain corporate-level operating expenses, patent claims and litigations, and other costs that are not allocated to product groups, as well as operating earnings of other products. In addition, depreciation and amortization expense is part of the manufacturing costs allocated to the segments and is neither identified as part of the inventory variation nor as part of the unused capacity charges; therefore, it cannot be isolated in cost of sales. Finally, public grants are allocated to the Company’s segments proportionally to the incurred expenses on the sponsored projects.

Wafer costs are allocated to the segments based on actual cost. From time to time, with respect to specific technologies, wafer costs are allocated to segments based on market price.

The following tables present the Company’s consolidated net revenues and consolidated operating income by reportable segment.

Net revenues by reportable segment:

The following is a summary of operations by entities located within the indicated geographic areas for 2023, 2022 and 2021. Net revenues represent sales to third parties from the country in which each subsidiary is domiciled. The Company is incorporated under Dutch law with head offices located in the Netherlands while the Company’s operational office and headquarters are located in Switzerland. Long-lived assets consist of property, plant and equipment, net. A significant portion of property, plant and equipment expenditures is attributable to front-end and back-end facilities, located in the different countries in which the Company operates. As such, the Company mainly allocates capital spending resources according to geographic areas rather than along product segment areas.

Interest Income (Expense), Net

INTEREST INCOME (EXPENSE), NET

Interest income (expense), net consisted of the following:

Income	226	71	13
Expense	(55)	(13)	(42)
Total	171	58	(29)

Interest income is related to cash and cash equivalents, short-term deposits and marketable securities held by the Company.

Interest income, net recorded in 2023 was composed of $226 million of interest income, partially offset by interest expense on borrowings and banking fees of $55 million.

Interest expense included the financial cost of the convertible bonds issued by the Company in 2020. On January 1, 2022, the Company adopted the new U.S. GAAP reporting guidance on distinguishing liabilities from equity and EPS. The new guidance was adopted by applying the modified retrospective method, under which prior year periods are not restated. Interest expense recorded in 2021 included a charge of $34 million related to the outstanding senior unsecured convertible bonds, mainly resulting from the non-cash accretion expense, as recorded under the previous accounting guidance. With the adoption of the new guidance, the finance cost of the convertible debt instruments outstanding at the date of adoption is limited to the amortization expense of debt issuance costs. The amortization expense of debt issuance costs amounted to $1 million for the year ended December 31, 2023, $1 million for the year ended December 31, 2022 and $3 million for the year ended December 31, 2021.

No borrowing cost was capitalized in 2023, 2022 and 2021. Nominal interest income received in cash on U.S. Treasury Bonds classified as available-for-sale marketable securities amounted to $15 million for the year ended December 31, 2023, $1 million for the year ended December 31, 2022 and $1 million for the year ended December 31, 2021.

Earnings of subsidiaries taxed at different rates	433	443	187
Income tax benefit (expense)	(541)	(520)	(331)

In 2022, the variation on the valuation allowance was related to the assessment of the recoverability of the deferred tax assets following the improved stability of profits of the Company in various jurisdictions.

The variation in the line "Effect of changes in tax laws and similar" in 2023 mainly relates to the recognition of a net deferred tax asset of $52 million related to a tax credit granted for technological activities, as well as the impact of the conclusion in 2023 of tax authority discussions resulting in the recognition of a net deferred tax asset of $81 million for intangibles recognized for tax purposes. These will be amortized over time and result in a future cash tax benefit.

The tax holidays represent a tax exemption period aimed to attract foreign technological investment in certain tax jurisdictions. The effect of the tax benefits, from tax holidays for countries which are profitable, on basic earnings per share was $0.05, $0.07 and $0.05 for the years ended December 31, 2023, 2022 and 2021, respectively. These agreements are present in various countries and include programs that reduce up to and including 100% of taxes in years affected by the agreements. The Company’s tax holidays expire at various dates through the year ending December 31, 2029. In certain countries, tax holidays can be renewed depending on the Company still meeting certain conditions at the date of expiration of the current tax holidays.

Component of the Net Deferred Tax Asset and Liability

Deferred tax assets and liabilities consisted of the following:

	December 31, 2023	December 31, 2022
Tax loss carryforwards, tax credits and other tax attributes	886	520
Less unrecognized tax benefits	(21)	(25)

Other temporary differences	(31)	(31)
Deferred tax liabilities	(342)	(318)
Net deferred income tax asset	538	542

For a particular tax-paying component of the Company and within a particular tax jurisdiction, all deferred tax liabilities and assets are offset and presented as a single amount in the balance sheet. The Company does not offset deferred tax liabilities and assets attributable to different tax-paying components or to different tax jurisdictions. The above table presents the deferred tax assets and liabilities before offset.

The variations in the lines "Tax losses carried forward, tax credits and other tax attributes" and "Valuation allowances” mainly include the recognition of deferred tax assets for a tax credit related to technological activities and the impact of the conclusion of discussions with the tax authorities for intangibles recognized for tax purposes, totaling $479 million decreased by $126 million related to the utilization of the tax losses in several jurisdictions following management’s assessment of the likelihood of future realization of the gross DTA recognized in the period.

The “Tax credits granted on capital investments” is mainly related to a 2003 agreement granting the Company certain tax credits for capital investments purchased through the year ending December 31, 2006. Any unused tax credits granted under the agreement will be impacted yearly by a legal inflationary index (currently 3.64% per annum). The credits may be utilized depending on the Company meeting certain program criteria and have no expiration date. In addition to this agreement, starting from 2007 the Company continues to receive tax credits on the yearly capital investments, which may be used to offset that year’s tax liabilities and increases by the legal inflationary rate. However, pursuant to the inability to utilize these credits currently and in future years,

the Company did not recognize any deferred tax asset on such tax allowance. As a result, there is no financial impact to the net deferred tax assets of the Company.

Deferred tax asset expiration

As of December 31, 2023, the Company and its subsidiaries have gross deferred tax assets on tax loss carryforwards, tax credits and other tax attributes that expire starting from 2024.

	December 31,
Year	2023
2024	3
2025	2
2026	2
2027	4
2028	3
Thereafter	872
Total	886

The amount reported on the line “Thereafter” includes tax attributes that expire in 2029 for $276 million and tax credit which will expire in 2030 for $203 million. The majority of the remaining amount has no expiration date.

Deferred Tax expense recognized through Other Comprehensive Income

In 2023, the Company recognized a deferred tax expense of $4 million as a component of other comprehensive income (loss), compared to a deferred tax expense of $26 million in 2022. They were related primarily to the tax effects of the recognized unfunded status on defined benefits plan.

Deferred tax on undistributed Earnings from foreign subsidiaries

The cumulative amount of distributable earnings related to the Company’s investments in foreign subsidiaries and corporate joint ventures was $7,575 million and $7,140 million as of December 31, 2023 and December 31, 2022, respectively. Due to the Company’s legal and tax structure, with the parent company established in the Netherlands, there is no significant tax impact from the distribution of earnings for $6,965 million from investments in foreign subsidiaries and corporate joint ventures. This is because there is no tax impact on dividends paid up to a Dutch holding company by qualifying investments. The amount of distributable earnings becoming taxable upon repatriation amount to $607 million. An amount of $387 million is indefinitely reinvested by the foreign subsidiaries. As of December 31, 2023, a deferred tax liability is recognized for $22 million on the amount of earnings expected to be repatriated in a foreseeable future.

Unrecognized Tax Benefits

A reconciliation of 2023, 2022 and 2021 beginning and ending amounts of unrecognized tax benefits is as follows:

	December 31, 2023	December 31, 2022	December 31, 2021
Balance at beginning of year	61	118	48
Additions based on tax positions related to the    current year	—	4	72
Additions based on acquisitions related to the    current year	—	—	—
Additions for tax positions of prior years	11	13	1
Reduction for tax positions of prior years	—	(69)	(1)
Settlements	(14)	(2)	—
Reductions due to lapse of statute of limitations	(4)	—	—
Foreign currency translation	1	(3)	(2)
Balance at end of year	55	61	118

In addition, as of December 31, 2023, $21 million of unrecognized tax benefits were classified as a reduction of deferred tax assets (as of December 31, 2022, the amount was $25 million). It is reasonably possible that certain of the uncertain tax positions disclosed in the table above could increase or decrease within the next 12 months due to ongoing tax audits. The Company is not able to make an estimate of the range of the reasonably possible change impacting the annual effective tax rate.

Additionally, the Company elected to classify accrued interest and penalties related to uncertain tax positions as components of income tax expense in the consolidated statements of income. They were less than $1 million in 2023, less than $1 million in 2022 and $1 million in 2021. Accrued interest and penalties amounted to $6 million as of December 31, 2023 and $6 million as of December 31, 2022.

The tax years that remain open for review from the tax authorities in the Company’s major tax jurisdictions are from 1997 to 2023.

Pillar II income taxes

Pillar II legislation has been enacted in certain jurisdiction the Company operates (Netherlands, the majority of the European Countries and Switzerland). The legislation will be effective for the Company's financial year beginning January 1, 2024. The Company is in the scope and has performed a preliminary assessment of the potential exposure of the Pillar II incomes taxes.

The assessment of the potential exposure to Pillar II income taxes is based on the most recent tax filings, 2022 country-by-country reporting and financial statements for the constituent entities in the Company. Based on the assessment, the Pillar II effective tax rates in most of the jurisdictions are above 15%. However, there is a limited number of jurisdictions where the transitional safe harbour relief does not apply and the Pillar II effective tax rate is slightly below 15%. Therefore, the Company expects a limited tax exposure to Pillar II income taxes in those jurisdictions. Pillar II income taxes impact will depend on the level of 2024 operating results within those jurisdictions as well as potential enactment of the Pillar II legislation or change in tax laws in those jurisdictions.

Diluted EPS	4.46	4.19	2.16

On January 1, 2022, the Company adopted the new guidance on distinguishing liabilities from equity and EPS by applying the modified retrospective method, under which prior year periods are not restated.

Under the previous guidance, the Company applied the treasury stock method to determine the dilutive effect of convertible bonds as past experience, existing stated policies, and the contractual terms of the bonds provided a reasonable basis to expect that the settlement would include cash, shares, or a mix of both.

With the adoption of the new guidance, the treasury stock method is no longer admitted and the application of the if-converted method is mandatory to determine the dilutive effect of convertible bonds. The senior unsecured convertible bonds issued on August 4, 2020 are consequently fully dilutive, with the total underlying shares presented in the line “Dilutive effect of convertible bonds” of the table above for the years ended December 31, 2023 and December 31, 2022.

Contingencies, Claims and Legal Proceedings

COMMITMENTS, CONTINGENCIES, CLAIMS AND LEGAL PROCEEDINGS

The Company's commitments relate to multi-annual agreements with suppliers when there is a fixed, non-cancelable commitment or when minimum payments are due on a committed delivery schedule. These commitments are primarily comprised of purchase commitments for outsourced foundry wafers ($1.1 billion) and firm contractual commitments related to power purchase and minimum energy efficiency, as part of the Company's actions to become carbon neutral by 2027 on scope 1 and 2 and partially scope 3 ($0.8 billion).

The Company is subject to possible loss contingencies arising in the ordinary course of business. These include but are not limited to: product liability claims and/or warranty cost on the products of the Company, contractual disputes, indemnification claims, claims for unauthorized use of third-party intellectual property, employee grievances, tax claims beyond assessed uncertain tax positions as well as claims for environmental damages. In determining loss contingencies, the Company considers the likelihood of impairing an asset or the incurrence of a liability at the date of the consolidated financial statements as well as the ability to reasonably estimate the amount of such loss. The Company records a provision for a loss contingency when information available before the consolidated financial statements are issued or are available to be issued indicates that it is probable that an asset has been impaired or a liability has been incurred at the date of the consolidated financial statements and when the amount of loss can be reasonably estimated. The Company regularly re-evaluates claims to determine whether provisions need to be readjusted based on the most current information available to the Company. Changes in these evaluations could result in an adverse material impact on the Company’s results of operations, cash flows or its financial position for the period in which they occur.

The Company has received and may in the future receive communications alleging possible infringements of third-party patents or other third-party intellectual property rights. Furthermore, the Company from time to time enters into discussions regarding a broad patent cross license arrangement with other industry participants. There is no assurance that such discussions may be brought to a successful conclusion and result in the intended agreement. The Company may become involved in costly litigation brought against the Company regarding patents, mask works, copyrights, trademarks or trade secrets. In the event that the outcome of any litigation would be unfavorable to the Company, the Company may be required to take a license to third-party patents and/or other intellectual property rights at economically unfavorable terms and conditions, and possibly pay damages for prior use and/or face an injunction, all of which individually or in the aggregate could have a material adverse effect on the Company’s results of operations, cash flows, financial position and/or ability to compete.

On December 4, 2023, a jury in the United States District Court for the Western District of Texas in Waco, Texas (USA) returned a verdict in a patent infringement lawsuit in favor of the plaintiff, Purdue University. The Court has not issued final judgment. If the Court issues a final judgment in the plaintiff’s favor, the Company will file post-trial motions and, if they are denied, the Company will file an appeal to the United States Court of Appeals for the Federal Circuit in Washington DC. The risk on this case is considered as possible and, based on the jury verdict, the possible loss is estimated at $32 million.

The Company has contractual commitments to various customers which could require the Company to incur costs to repair or replace defective products it supplies to such customer. The duration of these contractual commitments varies and, in certain cases, is indefinite. The Company is otherwise also involved in various lawsuits, claims, inquiries, inspections, investigations and/or proceedings incidental to its business and operations. Such matters, even if not meritorious, could result in the expenditure of significant financial or managerial resources. Any of the foregoing could have a material adverse effect on the Company’s results of operations, cash flows or its financial position.

The Company regularly evaluates claims and legal proceedings together with their related probable losses to determine whether they need to be adjusted based on the current information available to the Company. There can be no assurance that its recorded reserves will be sufficient to cover the extent of its potential liabilities. Legal costs associated with claims are expensed as incurred. In the event of litigation which is adversely determined with respect to the Company’s interests, or in the event the Company needs to change its evaluation of a potential third-party claim, based on new evidence or communications, a material adverse effect could impact its operations or financial condition at the time it were to materialize.

As of December 31, 2023 and 2022, respectively, provisions for estimated probable losses with respect to claims and legal proceedings were not considered material.

Fair Value Disclosures [Abstract]

Financial Instruments and Risk Management

FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

26.1     Financial risk factors

The Company is exposed to changes in financial market conditions in the normal course of business due to its operations in different foreign currencies and its ongoing investing and financing activities. The Company’s activities expose it to a variety of financial risks: market risk (including foreign exchange risk, fair value interest rate risk, cash flow interest rate risk and price risk), credit risk and liquidity risk. The Company’s overall risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the Company’s financial performance. The Company uses derivative financial instruments to hedge certain risk exposures.

Financial risk management is carried out by a central treasury department (Corporate Treasury). Additionally, a Treasury Committee, chaired by the Chief Financial Officer, steers treasury activities and ensures compliance with corporate policies. Treasury activities are thus regulated by the Company’s policies, which define procedures, objectives and controls. The policies focus on managing financial risk in terms of exposure to market risk, credit risk and liquidity risk. Treasury controls are subject to internal audits. Most treasury activities are centralized, with any local treasury activities subject to oversight from Corporate Treasury. Corporate Treasury identifies, evaluates and hedges financial risks in close cooperation with the Company’s subsidiaries. It provides written principles for overall risk management, as well as written policies covering specific areas, such as foreign exchange risk, interest rate risk, price risk, credit risk, use of derivative financial instruments, and investments of excess liquidity.

The majority of cash and cash equivalents is held in U.S. dollars and Euros and is placed with financial institutions rated at least a single “A” long-term rating from two of the major rating agencies, meaning at least A3 from Moody’s and A- from S&P and Fitch, or better. These ratings are closely and continuously monitored in order to manage exposure to the counterparty’s risk. Hedging transactions are performed only to hedge exposures deriving from operating, investing and financing activities conducted in the normal course of business.

Market risk

Foreign exchange risk

The Company conducts its business globally in various major international currencies. As a result, the Company is exposed to adverse movements in foreign currency exchange rates, primarily regarding the Euro. Foreign exchange risk mainly arises from recognized assets and liabilities at the Company’s subsidiaries and future commercial transactions.

Management has set up a policy to require the Company’s subsidiaries to hedge their entire foreign exchange risk exposure with the Company through financial instruments transacted or overseen by Corporate Treasury. Subsidiaries use forward contracts and purchased currency options to manage their foreign exchange risk arising from foreign-currency-denominated assets and liabilities. Foreign exchange risk arises when recognized assets and liabilities are denominated in a currency that is not the entity’s functional currency. These instruments do not qualify as hedging instruments for accounting purposes. Forward contracts and currency options, including collars, are also used by the Company to reduce its exposure to U.S. dollar fluctuations in Euro-denominated forecasted transactions that cover a large part of its R&D and corporate costs expenses as well as a portion of its front-end manufacturing costs of semi-finished goods. The Company also hedges through the use of currency forward contracts certain Singapore dollar-denominated manufacturing forecasted transactions. The derivative instruments used to hedge these forecasted transactions meet the criteria for designation as cash flow hedge. The hedged forecasted transactions have a high probability of occurring for hedge accounting purposes.

It is the Company’s policy to have the foreign exchange exposures in all the currencies hedged month by month against the monthly standard rate. At each month end, the forecasted flows for the coming month are hedged together with the fixing of the new standard rate. For this reason, the hedging transactions will have an exchange rate very close to the standard rate at which the forecasted flows will be recorded in the following month. As such, the foreign exchange exposure of the Company, which consists of the balance sheet positions and other contractually agreed transactions, is always close to zero and any movement in the foreign exchange rates will therefore not influence the exchange effect on items of the consolidated statement of income. Any discrepancy between the forecasted values and the actual results is constantly monitored and prompt actions are taken, if needed.

Derivative Instruments Not Designated as a Hedge

The Company enters into foreign currency forward contracts to reduce its exposure to changes in exchange rates and the associated risk arising from the denomination of certain assets and liabilities in foreign currencies at the Company’s subsidiaries. These include receivables from international sales by various subsidiaries, payables for foreign currency-denominated purchases and certain other assets and liabilities arising from intercompany transactions.

The notional amount of these financial instruments totaled $974 million, $931 million and $505 million on December 31, 2023, 2022 and 2021, respectively. The principal currencies covered at the end of the year 2023 are the China Yuan Renminbi, the Singapore dollar, the Euro, the Japanese yen, the Swiss franc, the Indian rupee, the Malaysian ringgit, the Moroccan dirham, the Philippines peso, the Swedish krona, the Taiwan dollar, and the South Korean won.

The risk of loss associated with forward contracts is equal to the exchange rate differential from the time the contract is entered into until the time it is settled. The risk of loss associated with purchased currency options is equal to the premium paid when the option is not exercised.

Foreign currency forward contracts not designated as cash flow hedge outstanding as of December 31, 2023 have remaining terms of 3 days to 166 days, maturing on average after 47 days.

Derivative Instruments Designated as a Hedge

To further reduce its exposure to U.S. dollar exchange rate fluctuations, the Company hedges through the use of currency forward contracts and currency options, including collars, certain Euro-denominated forecasted intercompany transactions that cover at year-end a large part of its R&D and SG&A expenses, as well as a portion of its front-end manufacturing costs of semi-finished goods within cost of sales. The Company also hedges through the use of currency forward contracts certain manufacturing transactions within cost of sales denominated in Singapore dollars.

The principles regulating the hedging strategy for derivatives designated as cash flow hedge are established as follows: (i) for R&D and corporate costs, up to 80% of the total forecasted transactions; (ii) for manufacturing costs, up to 70% of the total forecasted transactions. In order to follow a dynamic hedge strategy, the Company may change the percentage of the designated hedged item within the limit of 100% of the forecasted transaction. The maximum length of time over which the Company could hedge its exposure to the variability of cash flows for forecasted transactions is 24 months.

For the year ended December 31, 2023, the Company recorded a decrease in cost of sales of $1 million and a decrease in operating expenses of $4 million, related to the realized gains incurred on such hedged transactions. For the year ended December 31, 2022, the Company recorded an increase in cost of sales of $129 million and an increase in operating expenses of $68 million, related to the realized losses incurred on such hedged transactions. For the year ended December 31, 2021, the Company recorded a decrease in cost of sales of $15 million and a decrease in operating expenses of $4 million, related to the realized gains incurred on such hedged transactions.

The notional amount of foreign currency forward contracts and currency options, including collars, designated as cash flow hedge totaled $2,681 million, $3,192 million and $2,165 million on December 31, 2023, 2022 and 2021, respectively. The forecasted transactions hedged as of December 31, 2023 were determined to have a high probability of occurring.

As of December 31, 2023, $55 million of deferred gains on derivative instruments included in “Accumulated other comprehensive income (loss)” in the consolidated statements of equity were expected to be reclassified as earnings during the next 12 months based on the monthly forecasted R&D expenses, corporate costs and semi-finished manufacturing costs. Foreign currency forward contracts and collars designated as cash flow hedge outstanding as of December 31, 2023 have remaining terms of 4 days to 13 months, maturing on average after 113 days.

As of December 31, 2023, the Company had the following outstanding derivative instruments that were entered into to hedge Euro-denominated and Singapore dollar-denominated forecasted transactions:

In millions of Euros	Notional amount for hedge on forecasted R&D and other operating expenses	Notional amount for hedge on forecasted manufacturing costs
Forward contracts	445	951
Currency collars	240	640
In millions of Singapore dollars	Notional amount for hedge on forecasted R&D and other operating expenses	Notional amount for hedge on forecasted manufacturing costs
Forward contracts	—	219

Cash flow and fair value interest rate risk

The Company’s interest rate risk arises from long-term borrowings. Borrowings issued at variable rates expose the Company to cash flow interest rate risk. Borrowings issued at fixed rates expose the Company to fair value interest rate risk.

The Company analyses its interest rate exposure on a dynamic basis. Various scenarios are simulated taking into consideration refinancing, renewal of existing positions, alternative financing and hedging. The Company invests primarily on a short-term basis and as such the Company’s liquidity is invested in floating interest rate

instruments. As a consequence, the Company is exposed to interest rate risk due to potential mismatch between the return on its short-term floating interest rate investments and the portion of its long-term debt issued at fixed rate.

Price risk

As part of its ongoing investing activities, the Company may invest in publicly traded equity securities and be exposed to equity security price risk. In order to hedge the exposure to this market risk, the Company may enter into certain derivative hedging transactions.

Information on fair value of derivative instruments and their location in the consolidated balance sheets as of December 31, 2023 and December 31, 2022 is presented in the table below:

The Company entered into currency collars as combinations of two options, which are reported, for accounting purposes, on a net basis. As of December 31, 2023, the fair value of these collars represented assets for a net amount of $7 million (composed of $8 million assets offset with a $1 million liability). In addition, the Company entered into other derivative instruments, primarily forward contracts, which are governed by standard International Swaps and Derivatives Association (“ISDA”) agreements and are compliant with Protocols of the

European Market Infrastructure Regulation (“EMIR”), which are not offset in the statement of financial position and representing total assets of $53 million and liabilities of $4 million as of December 31, 2023.

The effect of derivative instruments designated as cash flow hedge on the consolidated statements of income for the year ended December 31, 2023 and December 31, 2022 and on the “Accumulated other comprehensive income (loss)” (“AOCI”) as reported in the consolidated statements of equity as of December 31, 2023 and December 31, 2022 is presented in the table below:

	Gain (loss) deferred in OCI on derivative		Location of gain (loss)	Gain (loss) reclassified from OCI into earnings
	December 31, 2023	December 31, 2022	reclassified from OCI into earnings	December 31, 2023	December 31, 2022

No significant ineffective portion of the cash flow hedge relationships was recorded in earnings for the years ended December 31, 2023 and December 31, 2022. No amount was excluded from effectiveness measurement on foreign exchange forward contracts and collars.

The effect on the consolidated statements of income for the year ended December 31, 2023 and December 31, 2022 of derivative instruments not designated as a hedge is presented in the table below:

	Location of gain	Gain (loss) recognized in earnings

Total		2	24

The Company did not enter into any derivative containing significant credit-risk-related contingent features.

  Credit risk

The expected credit loss and impairment methodology applied on each category of financial assets is further described in each respective note. While cash and cash equivalents are also subject to the expected credit loss model, the identified expected credit loss is deemed to be immaterial. The maximum credit risk exposure for all financial assets is their carrying amount.

Credit risk is the risk that a counterparty will not meet its obligations under a financial instrument or customer contract, leading to a financial loss. Credit risk typically arises from cash and cash equivalents, contractual cash flows of debt investments carried at amortized cost, the counterparty of derivative financial instruments and deposits with banks and financial institutions, as well as credit exposure to customers, including outstanding receivables.

The Company is exposed to credit risk from its operating activities (primarily for trade receivables) and from its financing activities, including deposits with banks and financial institutions, foreign exchange transactions and other financial instruments. Credit risk is managed at the Group level. The Company selects banks and/or financial institutions that operate with the group based on the criteria of long-term rating from at least two major Rating Agencies and keeping a maximum outstanding amount per instrument with each bank not to exceed 20% of the total. For derivative financial instruments, management has established limits so that, at any time, the fair value of contracts outstanding is not concentrated with any individual counterparty.

The Company monitors the creditworthiness of its customers to which it grants credit terms in the normal course of business. If certain customers are independently rated, these ratings are used. Otherwise, if there is no independent rating, risk control assesses the customer’s credit quality, considering its financial position, past experience and other factors. The utilization of credit limits is regularly monitored. Sales to customers are primarily settled in cash, which mitigates credit risk. As of December 31, 2023 and 2022, no customer represented more than 10% of trade accounts receivable, net. Any remaining concentrations of credit risk with respect to trade receivables are limited due to the large number of customers and their dispersion across many geographic areas.

The Company’s investments in instruments carried at amortized cost primarily include receivables towards government bodies. As such, they are investments with immaterial expected credit loss. Any remaining receivable is of low credit risk and is individually not significant. The credit ratings of the investments are monitored for credit deterioration.

Liquidity risk

Prudent liquidity risk management includes maintaining sufficient cash and cash equivalents, short-term deposits and marketable securities, the availability of funding from committed credit facilities and the ability to close out market positions. The Company’s objective is to maintain a significant cash position and a low debt-to-equity ratio, which ensures adequate financial flexibility. Liquidity management policy is to finance the Company’s investments with net cash from operating activities.

Management monitors rolling forecasts of the Company’s liquidity reserve based on expected cash flows.

26.2     Capital risk management

The Company’s objectives when managing capital are to safeguard the Company’s ability to continue as a going concern in order to create sustainable value, benefits and returns for its stakeholders, as to maintain an optimal capital structure. In order to maintain or adjust its capital structure, the Company may review the amount of dividends paid to shareholders, return capital to shareholders, or issue new shares.

Consistent with other peers in the industry, the Company monitors capital on the basis of the net debt-to-equity ratio. This ratio is calculated as the net financial position of the Company, defined as the difference between total cash position (cash and cash equivalents, short-term deposits, marketable securities and restricted cash, if any) and total financial debt (short-term and long-term debt), divided by total parent company stockholders’ equity.

26.3     Fair value measurement

The fair value of financial instruments traded in active markets is based on quoted market prices at the balance sheet date. The quoted market price used for financial assets held by the Company is the bid price. If the market for a financial asset is not active and if no observable market price is obtainable, the Company measures fair value by using significant assumptions and estimates. When measuring fair value, the Company makes maximum use of market inputs and minimizes the use of unobservable inputs.

The table below details financial assets (liabilities) measured at fair value on a recurring basis as of December 31, 2023:

	Fair Value Measurements using

For liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3), the reconciliation between January 1, 2023 and December 31, 2023 is presented as follows:

	Fair Value Measurements using Significant Unobservable Inputs (Level 3)

Changes in fair value measurement	(12)
Currency translation adjustment	1
December 31, 2023	20
Amount of total gains (losses) for the period included in earnings attributable to liabilities    still held at the reporting date	12

Contingent consideration reported as liabilities on the consolidated balance sheet as of December 31, 2023 and December 31, 2022 is based on the probability that the milestones defining the variable components of the

consideration will be achieved. In 2023, the probability of achievement of these variable components was reassessed, resulting in a reduction of $12 million of the fair value of the contingent consideration related to a certain business acquisition from 2020. The Company reported this change in fair value in the line “Research and development expenses” of the consolidated statement of income.

For liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3), the reconciliation between January 1, 2022 and December 31, 2022 is presented as follows:

	Fair Value Measurements using Significant Unobservable Inputs (Level 3)
January 1, 2022	77
Changes in fair value measurement	(35)
Currency translation adjustment	(4)
Payments made	(7)
December 31, 2022	31
Amount of total gains (losses) for the period included in earnings attributable to liabilities    still held at the reporting date	35

No asset (liability) was measured at fair value on a non-recurring basis using significant unobservable inputs (Level 3) as of December 31, 2023 and December 31, 2022.

The Company evaluated in 2023, 2022 and 2021 for impairment the aggregate carrying amount of long-term investments for which the Company applies the cost method as a measurement alternative, as described in Note 2.22. No significant impairment charge was recorded on these investments in 2023, 2022 and 2021.

The following table includes additional fair value information on financial assets and liabilities as of December 31, 2023 and 2022:

	2023			2022
	Level	Carrying Amount	Estimated Fair Value	Carrying Amount	Estimated Fair Value
Cash equivalents (1)	1	2,879	2,879	2,996	2,996
Marketable securities	1	1,635	1,635	679	679
Short-term, deposits	1	1,226	1,226	581	581
Long-term debt
– Bank loans (including current portion)	2	1,366	1,366	1,165	1,165
– Finance leases (including current portion)	2	65	65	57	57
– Senior unsecured convertible bonds issued on August 4, 2020 (2)	1	1,496	1,814	1,495	1,561

(1)     Cash equivalents primarily correspond to deposits at call with banks.

(2)     The carrying amount as of December 31, 2023, of the senior unsecured convertible bonds as reported above, corresponds to the nominal value of the bonds, net of $4 million unamortized debt issuance costs. The fair value represented the market price of the bonds trading on the Frankfurt Stock Exchange.

The methodologies used to estimate fair value are as follows:

Components	Methodology used to estimate fair value
Debt securities classified as available-for-sale	Quoted market prices for identical instruments
Foreign exchange forward contracts, currency options and collars	Quoted market prices for similar instruments
Equity securities measured at fair value through earnings	Quoted market prices for identical instruments
Equity securities carried at cost as a measurement alternative	Valuation of the underlying investments on a new round of third-party financing or upon liquidation
Long-term debt and current portion of long-term debt	Future cash flows on a borrowing-by-borrowing basis and discounting these future cash flows using the Company's incremental borrowing rates for similar types of borrowing arrangements. For convertible bonds, the fair value represents the market price of the bonds trading on the Frankfurt Stock Exchange
Cash and cash equivalents, short-term deposits, accounts receivable, short-term borrowings, and accounts payable	The carrying amounts reflected in the consolidated financial statements are considered as reasonable estimates of fair value due to the relatively short period of time between the origination of the instruments and their expected realization.

Accounting Policies [Abstract]

Basis of presentation and consolidation

Basis of presentation and consolidation

The Company's consolidated financial statements include the assets, liabilities, results of operations and cash flows of its wholly-owned and majority-owned subsidiaries, after elimination of intercompany transactions and balances. Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are deconsolidated from the date that control ceases.

The Company assesses each investment in equity securities to determine whether the investee is a Variable Interest Entity (“VIE”). The Company consolidates the VIEs for which the Company is determined to be the primary beneficiary. The primary beneficiary of a VIE is the party that: (i) has the power to direct the most significant activities of the VIE and (ii) is obligated to absorb losses or has the rights to receive returns that would be considered significant to the VIE.

When the Company owns some, but not all, of the voting stock of a consolidated entity, the shares held by third parties represent a noncontrolling interest. The consolidated financial statements are prepared based on the total amount of assets and liabilities and income and expenses of the consolidated subsidiaries. However, the portion of these items that does not belong to the Company’s shareholders is reported in the line “Noncontrolling interest” of the consolidated financial statements.

Use of estimates

Use of estimates

The preparation of consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions. The primary areas that require significant estimates and judgments by management include, but are not limited to:

•sales allowances for discounts, price protection, product returns and other rebates,

•inventory obsolescence reserves and normal manufacturing capacity thresholds to determine costs capitalized in inventory,

•recognition and measurement of loss contingencies,

•valuation at fair value of assets acquired and liabilities assumed on business acquisitions, and measurement of any contingent consideration,

•annual and trigger-based impairment review of goodwill and intangible assets, as well as the assessment of events which could trigger impairment testing on tangible assets,

•assessment of the Company’s long-lived assets economic useful lives,

•assumptions used in measuring expected credit losses and impairment charges on financial assets,

•assumptions used in assessing the number of awards expected to vest on stock-based compensation plans,

•assumptions used in calculating net defined pension benefit obligations and other long-term employee benefits,

•determination of the amount of tax expected to be paid and tax benefit expected to be received, including deferred income tax assets, valuation allowance and provisions for uncertain tax positions and claims.

The Company bases the estimates and assumptions on historical experience and on various other factors such as market trends, market information used by market participants and the latest available business plans that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. While the Company regularly evaluates its estimates and assumptions, the actual results experienced by the Company could differ materially and adversely from those estimates.

Foreign currency

Foreign currency

The U.S. dollar is the reporting currency of the Company. The U.S. dollar is the currency of the primary economic environment in which the Company operates since the worldwide semiconductor industry uses the U.S. dollar as a currency of reference for actual pricing in the market. Furthermore, the majority of the Company’s transactions are denominated in U.S. dollars, and revenues from external sales in U.S. dollars largely exceed revenues in any other currency. However, certain significant costs are incurred in the countries of the Eurozone and other non-U.S. dollar currency areas.

The functional currency of each subsidiary of the Company is either the local currency or the U.S. dollar, depending on the basis of the economic environment in which each subsidiary operates. Foreign currency transactions, including operations in local currency when the U.S. dollar is the functional currency, are measured into the functional currency using the prevailing exchange rate. Foreign exchange gains and losses resulting from the re-measurement at reporting date of monetary assets and liabilities denominated in currencies other than the functional currency are recognized in the line “Other income and expenses, net” of the consolidated statements of income.

For consolidation purposes, the results and financial position of the subsidiaries whose functional currency is different from the U.S. dollar are translated into the reporting currency as follows:

(a)assets and liabilities for each consolidated balance sheet presented are translated into U.S. dollars using exchange rates at the balance sheet dates;

(b)income and expenses for each consolidated statement of income presented are translated into U.S dollars using the monthly exchange rates;

(c)the resulting exchange differences are reported as Currency Translation Adjustments (“CTA”), a component of “Other comprehensive income (loss)” in the consolidated statements of comprehensive income.

Cash and cash equivalents

Cash and cash equivalents

Cash and cash equivalents include cash on hand, deposits held at call with external financial institutions and other short-term highly liquid investments with effective maturities of three months or less. They are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates.

Short-term deposits representing cash equivalents with maturity beyond three months and below one year are reported as current assets in the line “Short-term deposits” of the consolidated balance sheets.

Trade accounts receivable

Trade accounts receivable

Trade accounts receivable are amounts due from customers for goods sold and services rendered to third parties in the ordinary course of business. The Company uses a lifetime expected losses allowance for all trade receivables. The allowance includes reasonable assumptions about future credit trends. The historical loss rates are adjusted to reflect current and forward-looking information on macro-economic factors affecting the ability of the Company’s customers to settle the receivables. Adjustments to the expected credit losses allowance are reported on the line “Selling, general and administrative expenses” in the consolidated statements of income and write-offs, if any, are recorded against the expected credit losses allowance.

In the event of transfers of receivables such as factoring, the Company derecognizes the receivables only to the extent that the Company has surrendered control over the receivables in exchange for a consideration other than beneficial interest in the transferred receivables.

Inventories

Inventories

Inventories are stated at the lower of cost and net realizable value. Actual cost is based on an adjusted standard cost, which approximates cost on a first-in, first-out basis for all categories of inventory (raw materials, work-in-process, finished products). Actual cost is therefore dependent on the Company’s manufacturing performance and is based on the normal utilization of its production capacity. In case of underutilization of manufacturing facilities, the costs associated with unused capacity are not included in the valuation of inventories but charged directly to cost of sales. Net realizable value is based upon the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation.

Inventory reserve is estimated for excess uncommitted inventory based on historical sales data, order backlog and production plans. The Company performs, on a continuous basis, write-offs of inventories, which have the characteristics of slow-moving, old production dates and technical obsolescence. The Company evaluates its inventory to identify obsolete or slow-selling items, as well as inventory that is not of saleable quality and records a specific reserve if the Company estimates the inventory will eventually be written off.

Income taxes

Income taxes

Income tax for the period comprises current and deferred income tax. Income tax expense represents the income tax expected to be paid related to the current year taxable profit in each tax jurisdiction. Deferred income tax is recognized for all temporary differences arising between the tax bases of assets and liabilities and their carrying amount in the consolidated financial statements. Deferred tax assets are also recognized on temporary differences arising from tax losses carried forward and tax credits. Deferred tax liabilities are not recognized on the initial recognition of goodwill as a result of a business combination. Deferred income tax is determined using tax rates and laws that are enacted at the balance sheet date and are expected to apply when the related deferred income tax asset is realized or the deferred income tax liability is settled. The effect on deferred tax assets and liabilities from changes in tax laws and tax rates is recognized on the line “Income tax expense” in the consolidated statements of income in the period in which the law is enacted. Deferred income tax assets are recognized in full but the Company assesses whether future taxable profit will be available against which temporary differences can be utilized. A valuation allowance is provided for deferred tax assets when management considers it is more likely than not that they will not be realized.

The Company recognizes a deferred tax liability on undistributed earnings of subsidiaries when there is a presumption that taxable earnings will be remitted to the parent. A deferred tax asset is recognized on

compensation for the grant of stock awards to the extent that such charge constitutes a temporary difference in the subsidiaries’ local tax jurisdictions. Changes in the stock price do not result in any adjustments to the deferred tax asset prior to vesting.

At each reporting date, the Company assesses all significant income tax positions in all tax jurisdictions to determine any uncertain tax positions. The Company uses a two-step process for the evaluation of uncertain tax positions. The first step consists in assessing whether the tax benefit must be recognized. The second step consists in measuring the amount of tax benefit to be recognized on each uncertain tax position. In step 1 (recognition), the Company assesses whether a tax position, based solely on its technical merits, is more likely than not to be sustained upon examination. Only tax positions with a sustainability threshold higher than 50% are recognized. In Step 2 (measurement), the Company determines the amount of recognizable tax benefit. The measurement methodology is based on a “cumulative probability” approach, resulting in the recognition of the largest amount that is greater than 50% likely of being realized upon settlement with the taxing authority. The Company accrues for interest and penalties on uncertain tax liabilities reported on the consolidated balance sheets. Interests and penalties are classified as components of income tax expense in the consolidated statements of income.

Business combinations and goodwill

Business combinations and goodwill

The acquisition method of accounting is applied to all business combinations. The identifiable assets acquired, liabilities assumed, and equity instruments issued are measured at acquisition date fair value. Any contingent consideration is recorded at acquisition date fair value and remeasured at each reporting date. Acquisition-related transaction costs and restructuring costs related to the acquired business are expensed as incurred. Acquired in-process research and development (“IPR&D”) is capitalized and recorded as an intangible asset at acquisition date, subject to impairment testing until the research or development is completed. The excess of the consideration transferred over the acquisition-date fair value of the identifiable assets acquired and liabilities assumed, net of related deferred tax impacts, is recorded as goodwill. In case of a bargain purchase, the Company reassesses whether it has correctly identified all of the assets acquired and all of the liabilities assumed, the noncontrolling interest in the acquiree, if any, the Company’s previously held equity interest in the acquiree, if any, and the consideration transferred. If after this review, a bargain purchase is still indicated, it is recognized in earnings attributable to parent company stockholders. The purchase of additional interests in a partially owned subsidiary is treated as an equity transaction as well as all transactions concerning the sale of subsidiary stock or the issuance of stock by the partially owned subsidiary, assuming there is no change in control of the subsidiary. In the case of a sale of subsidiary shares, whereby the Company no longer maintains control of the subsidiary, the Company recognizes a gain or loss in earnings.

Goodwill is carried at cost less accumulated impairment losses, if any. Goodwill is not amortized but is tested for impairment at least annually, and more frequently whenever events or changes in circumstances indicate that the carrying amount of goodwill may not be recoverable. Goodwill subject to potential impairment is tested at the reporting unit level. The impairment test determines whether the fair value of each reporting unit under which goodwill is allocated is lower than the total carrying amount of relevant net assets allocated to such reporting unit, including its allocated goodwill. The Company records an impairment loss on goodwill when a reporting unit’s carrying value exceeds its fair value. Significant management judgments and estimates are used in forecasting the future discounted cash flows associated with the reporting unit, including: the applicable industry’s sales volume forecast and selling price evolution, the reporting unit’s market penetration and its revenues evolution, the market acceptance of certain new technologies and products, the relevant cost structure, the discount rates applied using a weighted average cost of capital and the perpetuity rates used in calculating cash flow terminal values.

Intangible assets with definite useful lives

Intangible assets with definite useful lives

Intangible assets subject to amortization include intangible assets purchased from third parties recorded at cost and intangible assets acquired in business combinations initially recorded at fair value. Amortization begins when the intangible asset is available for its intended use. Amortization reflects the pattern in which the asset’s economic benefits are consumed, which usually consists in applying the straight-line method to allocate the cost of the intangible assets over their estimated useful lives.

The carrying value of intangible assets with definite useful lives is evaluated whenever changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for

the amount by which the asset’s carrying amount exceeds its fair value. The Company evaluates the remaining useful life of an intangible asset at each reporting date to determine whether events and circumstances warrant a revision to the remaining period of amortization.

Technologies and licenses

Separately acquired technologies and licenses are recorded at historical cost. Technologies and licenses acquired in a business combination are initially recognized at acquisition date fair value. Technologies and licenses have a useful life which usually ranges from 3 to 11 years and are carried at cost less accumulated amortization and impairment losses, if any.

Computer software

Separately acquired computer software is recorded at historical cost. Costs associated with maintaining computer software programs are expensed as incurred and reported as “Cost of sales”, “Selling, general and administrative expenses”, or “Research and development expenses” in the consolidated statements of income according to their intended use. The capitalization of costs for internally generated software developed by the Company for its internal use begins when the preliminary project stage is completed and when the Company, implicitly or explicitly, authorizes and commits to funding a computer software project. It must be probable that the project will be completed and will be used to perform the function intended. Amortization of computer software begins when the software is available for its intended use and is calculated using the straight-line method over the estimated useful life, which does not exceed 4 years.

Property, plant and equipment

Property, plant and equipment

Property, plant and equipment are stated at historical cost, net of accumulated depreciation and any impairment losses. Property, plant and equipment acquired in a business combination are initially recognized at acquisition date fair value. Major additions and improvements are capitalized, while minor replacements and repairs are expensed and reported as “Cost of sales”, “Selling, general and administrative expenses”, or “Research and development expenses” in the consolidated statements of income according to their intended use.

Land is not depreciated. Depreciation on fixed assets is computed using the straight-line method over their estimated useful lives, as follows:

Buildings	33 years
Facilities and leasehold improvements	5-10 years
Machinery and equipment	2-10 years
Computer and R&D equipment	3-6 years
Other	2-5 years

The Company also evaluates, and adjusts if appropriate, the assets’ useful lives.

Property, plant and equipment are periodically reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or a group of assets may not be recoverable. Several impairment indicators exist for making this assessment, such as: restructuring plans, significant changes in the technology, market, economic or legal environment in which the Company operates, available evidence of obsolescence of the asset, or indication that its economic performance is, or will be, worse than expected. In determining the recoverability of assets to be held and used, the Company initially assesses whether the carrying value of the tangible assets or group of assets exceeds the undiscounted cash flows associated with these assets. If exceeded, the Company then evaluates whether an impairment charge is required by determining if the asset’s carrying value also exceeds its fair value. This fair value is normally estimated by the Company based on independent market appraisals or the sum of discounted future cash flows, using market assumptions such as the utilization of the Company’s fabrication facilities and the ability to upgrade such facilities, change in the selling price and the adoption of new technologies. Any impairment loss is reported on the same income statement line as the depreciation expense recorded on the impaired group of assets, except in case of closure of operating sites or major restructuring plans and reorganizations. In such case, any impairment loss is reported on the line “Impairment, restructuring charges and other related closure costs” in the consolidated statements of income.

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are included in “Other income and expenses, net” in the consolidated statements of income.

The Company did not hold any significant assets held for sale as of December 31, 2023 and December 31, 2022.

Leases

Leases

A lease contract is a contract, or part of a contract, that conveys the right to control the use of an identified asset for a period of time in exchange for consideration. If a lease is identified, classification between finance or operating is determined at lease commencement. Most leases entered by the Company are operating leases. Operating lease liabilities are recognized at the present value of the future lease payments at the lease commencement date. The rate implicit in the lease should be used as a discount rate whenever that rate is readily determinable. In most cases, this rate is not readily determinable and therefore, the Company uses its incremental borrowing rate, which is derived from information available at the lease commencement date. The Company considers its recent debt issuances as well as publicly available data for instruments with similar characteristics when calculating its incremental borrowing rates. Operating lease right-of-use assets are based on the corresponding lease liability adjusted for any lease payments made at or before commencement, initial direct costs, and lease incentives.

Right-of-use assets are included in the line “Property, plant and equipment, net” of the consolidated balance sheets. Operating lease liabilities due within one year are included in the line “Other payables and accrued liabilities”, while non-current operating lease liabilities are included in the line “Other long-term liabilities” of the Company’s consolidated balance sheets. Operating lease expenses are recognized in the consolidated statements of income, on a straight-line basis since the lease commencement date over the lease period and reported as “Cost of sales”, “Selling, general and administrative expenses”, or “Research and development expenses”, according to the intended use of the leased asset.

Finance lease liabilities due within one year are included in the line “Short-term debt”, while non-current finance lease liabilities are included in the line “Long-term debt” of the Company’s consolidated balance sheets. Right-of-use assets for finance leases are depreciated on a straight-line basis since the lease commencement date over the lease period or the estimated useful life of the leased asset in case of transfer of ownership or purchase option that is reasonably certain to be exercised. The depreciation expense is reported as “Cost of sales”, “Selling, general and administrative expenses”, or “Research and development expenses”, according to the intended use of the leased asset.

Certain lease contracts contain options to extend the lease. On these contracts, the Company estimates the lease term by including the extended duration when it is reasonably certain for the Company to exercise that option. In addition, for short-term leases, defined as leases with a term of twelve months or less, the Company elected the practical expedient to not recognize an associated lease liability and right-of-use asset. The short-term lease election is made at the commencement date only. Additionally, lease contracts with a sum of lease payments not exceeding $5,000 are excluded from recognition on the consolidated balance sheet.

The right-of-use asset is a non-monetary asset while the lease liability is a monetary liability. When accounting for a lease that is denominated in a foreign currency, the lease liability is remeasured using the current exchange rate, while the right-of-use asset is measured using the historical exchange rate as of the commencement date.

The Company does not separate lease and non-lease components and instead accounts for each separate lease component and the non-lease components associated with that lease component as a single lease component.

Variable lease payments that depend on an index or a rate are included in the lease payments and are measured using the prevailing index or rate at the measurement date. Changes to index and rate-based variable lease payments are recognized in earnings in the period of the change.

Loss contingencies

Loss contingencies

In determining loss contingencies, the Company considers the likelihood of the incurrence of a liability as well as the ability to reasonably estimate the amount of such loss or liability. An estimated loss from a loss contingency is accrued when information available indicates that it is probable that a liability has been incurred at the date of the consolidated financial statements and when the amount of the loss can be reasonably estimated.

Long-term debt

Long-term debt

(a)Convertible debt

On January 1, 2022, the Company adopted the new guidance on distinguishing liabilities from equity by applying the modified retrospective approach, with the impact upon transition recorded in retained earnings for instruments outstanding as of the date of adoption of the new guidance. Prior to the new guidance, components of convertible debt instruments that may be settled in cash upon conversion based on a net-share settlement basis were accounted for separately as long-term debt and equity when the conversion feature of the convertible bonds constituted an embedded equity instrument. When an equity instrument was identified, proceeds from issuance were allocated between debt and equity by measuring first the liability component and then determining the equity component as a residual amount. The liability component was measured as the fair value of a similar non-convertible debt, which resulted in the recognition of a debt discount. In subsequent periods, the Company amortized the debt discount through earnings in the line “Interest income (expense), net” of the consolidated statements of income, using the effective interest method, based on the contractual maturity of the debt. The equity component, reported on the line “Additional paid-in capital” of the consolidated statement of equity, was not remeasured. Deferred taxes were recognized on the difference between the carrying amount of the liability component and its tax basis. In case of conversion from the bondholders, the fair value of the consideration transferred was allocated between the liability component and the equity component. The difference between the carrying amount of the debt at the settlement date and the fair value of the debt component was recorded in earnings as a loss on debt extinguishment and reported in the line “Loss on financial instruments, net” of the consolidated statements of income. The liability component was measured as the fair value of a similar non-convertible debt prior to settlement. The reacquired equity component was recorded in equity and reported on the line “Additional paid-in capital” of the consolidated statement of equity.

The new accounting guidance adopted on January 1, 2022 has eliminated the cash conversion model described above. At initial recognition, total cash proceeds received at issuance are reported as financial debt and no equity conversion instrument is recorded separately in equity. On subsequent periods, the carrying value of the convertible debt is incremented up to its nominal value over the amortization pattern of any unamortized debt discount and issuance costs.

Debt issuance costs are reported as a deduction of debt. They are subsequently amortized through earnings on the line “Interest income (expense), net” of the consolidated statements of income, using the effective interest rate method.

(b)Bank loans

Bank loans and non-convertible senior bonds are recognized at the amount of cash proceeds received, net of debt issuance costs incurred. They are subsequently reported at amortized cost; any difference between the proceeds (net of debt issuance costs) and the principal amount is recognized through earnings on the line “Interest income (expense), net” of the consolidated statements of income over the period of the borrowings using the effective interest method.

Employee benefits

Employee benefits

(a) Pension obligations

The Company sponsors various pension schemes for its employees. These schemes conform to local regulations and practices in the countries in which the Company operates. Such plans include both defined benefit and defined contribution plans. For defined benefit pension plans, the liability recognized in the consolidated balance sheets is the present value of the defined benefit obligation at the balance sheet date less the fair value of plan assets. The funded status of the defined benefit plans is calculated as the difference between plan assets and the projected benefit obligations. Estimates are used in determining the assumptions incorporated in the calculation of the pension obligations, which is supported by input from independent actuaries. Actuarial gains and losses arising from changes in actuarial assumptions are recognized in “Accumulated other comprehensive income (loss)” in the consolidated statements of equity and are charged or credited to earnings over the employees’ average remaining service period using the corridor amortization method. Past service costs are recognized in earnings on the line “Other components of pension benefit costs” of the consolidated statements of income if the changes to the pension scheme are not conditional on the employees remaining in service for a specified period. Other past service costs are recognized in “Accumulated other comprehensive income (loss)”

in the consolidated statements of equity and are amortized on a straight-line basis over the average remaining service period. The net periodic benefit cost of the year is determined based on the assumptions used at the end of the previous year.

The service cost component of net periodic benefit costs is presented in the same income statement line as other employee compensation costs arising from services rendered during the period. The other components of the net periodic benefit cost are presented separately, outside operating income, on the line “Other components of pension benefit costs” of the consolidated statements of income. These elements include: interest cost; expected return on plan assets; amortization of transition (asset) obligation; amortization of prior service cost; amortization of net (gain) loss; (gain) loss recognized due to curtailment or settlement and; cost of special termination benefits.

For defined contribution pension plans, the Company pays contributions to publicly or privately administered pension insurance plans on a mandatory, contractual or voluntary basis. The Company has no further payment obligations once the contributions have been paid. The contributions are recognized as employee benefit expense when they are due. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in the future payments is available.

(b) Termination benefits

Termination benefits are payable when an employee is involuntarily terminated, or whenever an employee accepts voluntary termination in exchange for termination benefits. For the accounting treatment and timing of recognition of involuntary termination benefits, the Company distinguishes between one-time termination benefit arrangements and ongoing termination benefit arrangements. A one-time termination benefit arrangement is established by a termination plan and applies to a specified termination event. One-time involuntary termination benefits are recognized as a liability when the termination plan meets certain criteria and has been communicated to employees. If employees are required to render future service in order to receive these one-time termination benefits, the liability is recognized ratably over the future service period. Termination benefits other than one-time termination benefits are termination benefits for which the communication criterion is not met but that are committed to by management, or termination obligations that are not specifically determined in a new and single plan. These termination benefits are all legal, contractual and past practice termination obligations to be paid to employees in case of involuntary termination. These termination benefits are accrued for when commitment creates a present obligation to others for the benefits expected to be paid, when it is probable that employees will be entitled to the benefits and the amount can be reasonably estimated.

In case of special termination benefits related to voluntary redundancy programs, the Company recognizes a provision for voluntary termination benefits at the date on which the employee irrevocably accepts the offer and the amount can be reasonably estimated.

(c) Profit-sharing and bonus plans

The Company recognizes a liability and an expense for bonuses and profit-sharing plans when a contractual obligation exists or when there is a past practice that has created a present obligation.

(d) Other long-term employee benefits

The Company provides long-term employee benefits such as seniority awards in certain countries. The entitlement to these benefits is usually conditional on the employee completing a minimum service period. The expected costs of these benefits are accrued over the period of employment. Actuarial gains and losses arising from changes in actuarial assumptions are charged or credited to earnings in the period of the revised estimate. These obligations are valued annually with the assistance of independent qualified actuaries.

(e) Share-based compensation

The Company accounts for stock-based compensation for all stock-based awards granted to senior executives and selected employees, including awards that vest upon the satisfaction of a service condition and awards that vest upon the satisfaction of both a service condition and a performance condition. Both equity awards vest over

a three-year service period while performance-based awards also require the Company’s attainment of certain performance conditions. The Company measures the cost of the awards based on the related grant-date fair value, reflecting the market price of the underlying shares at the date of the grant, reduced by the present value of the dividends expected to be paid during the requisite service period. That cost is recognized ratably over the period during which an employee is required to provide service in exchange for the award. The compensation cost is recorded through earnings with the corresponding amount reported in equity, under “Additional paid-in capital” of the consolidated statements of equity. The compensation cost is calculated based on the number of awards expected to vest, net of an estimated number of awards to be forfeited due to the employees failing to satisfy the service condition or one or more performance conditions. By the end of the vesting period, compensation is recognized only for the awards that ultimately vest.

Liabilities for the Company’s portion of payroll taxes are recognized at vesting, which is the event triggering the payment of the social contributions in most of the Company’s local tax jurisdictions. Employee-related social charges are measured based on the intrinsic value of the share and recorded at vesting date.

Share capital

Share capital

Ordinary shares are classified as “Common stock” within equity on the consolidated balance sheets. Incremental costs directly attributable to the issuance of new shares are shown in equity as a deduction, net of tax, from the proceeds received.

Where the Company purchases its own equity share capital (treasury stock), the consideration paid, including any directly attributable incremental costs (net of income taxes), is deducted from parent company stockholders’ equity until the shares are cancelled, reissued, or disposed of.

Comprehensive income (loss)

Comprehensive income (loss)

Comprehensive income (loss) is defined as the change in equity of a business during a period except those changes resulting from investment by and distributions to stockholders. In the consolidated financial statements, “Other comprehensive income (loss)” and “Accumulated other comprehensive income” primarily consists of foreign currency translation adjustments, unrealized gains (losses) on debt securities classified as available-for-sale, unrealized gains (losses) on derivatives designated as cash flow hedge and the accounting for defined benefit plans, net of tax.

Revenue recognition

Revenue recognition

Arrangements with customers are considered contracts if all the following criteria are met: (a) parties have approved the contract and are committed to perform their respective obligations; (b) each party’s rights regarding the goods or services to be transferred can be identified; (c) payment terms for the goods or services to be transferred can be identified; (d) the contract has commercial substance and (e) collectability of substantially all of the consideration is probable. The Company recognizes revenue from products sold to a customer, including distributors, when it satisfies a performance obligation by transferring control over a product to the customer. The Company may also enter into several multi-annual capacity reservation and volume commitment arrangements with certain customers. These agreements constitute a binding commitment for the customers to purchase and for the Company to supply allocated commitment volumes in exchange for additional consideration. The consideration related to commitment fees is reported as revenues from sale of products as it is usually based on delivered quantities.

In certain circumstances, the Company may enter into agreements that concern principally revenues from services, where the performance obligation is satisfied over time. The objective when allocating the transaction price is to allocate the transaction price to each performance obligation (or distinct good or service) in an amount that depicts the amount of consideration to which the Company expects to be entitled in exchange for transferring the promised goods or services to the customer. The payment terms typically range between 30 to 90 days. Certain customers require the Company to hold inventory as consignment in their hubs and only purchase inventory when they require it. Revenue for sales of such inventory is recognized when, at the customer’s option, the products are withdrawn from the consignment and the Company satisfies a performance obligation by transferring control over a product to the customer.

Consistent with standard business practice in the semiconductor industry, price protection is granted to distribution customers on their existing inventory of the Company’s products to compensate them for changes in market prices. The Company accrues a provision for price protection based on a rolling historical price trend computed monthly as a percentage of gross distributor sales. This historical price trend represents differences in recent months between the invoiced price and the final price to the distributor, adjusted to accommodate a significant change in the selling price. The short outstanding inventory time, visibility into the inventory product pricing and long distributor pricing history have enabled the Company to reliably estimate price protection provisions at period-end. The Company records the accrued amounts as a deduction of “Net sales” in the consolidated statements of income at the time of the sale.

The Company’s customers occasionally return the Company’s products for technical reasons. The Company’s standard terms and conditions of sale provide that if the Company determines that products do not conform, the Company will repair or replace the non-conforming products, or issue a credit note or rebate of the purchase price. Quality returns are identified shortly after sale in customer quality control testing. The Company records the accrued amounts as a deduction of “Net sales” in the consolidated statements of income, using contractual and historical information.

The Company records a provision for warranty costs as a charge against “Cost of sales” in the consolidated statements of income, based on historical trends of warranty costs incurred as a percentage of sales, which management has determined to be a reasonable estimate of the probable losses to be incurred for warranty claims in a period. Any potential warranty claims are subject to the Company’s determination that the Company is at fault for damages, and such claims must usually be submitted within a short period of time following the date of sale. This warranty is given in lieu of all other warranties, conditions or terms expressed or implied by statute or common law. The Company’s contractual terms and conditions typically limit its liability to the sales value of the products which gave rise to the claims.

The Company’s insurance policy relating to product liability covers third-party physical damages and bodily injury, indirect financial damages as well as immaterial non-consequential damages caused by defective products.

In addition to product sales, the Company enters into arrangements with customers consisting in transferring licenses or related to license services. The revenue generated from these arrangements are reported on the line “Other revenues” of the consolidated statements of income.

Public funding

Public funding

The Company receives funding from several governmental agencies and income is recognized when all contractual conditions for receipt of these funds are fulfilled and eligible expenditures incurred. Such funding is generally provided to encourage research, development and other innovation activities, industrialization deployment and local economic development. The conditions to receive government funding may include eligibility restrictions, approval by the local governmental authorities, annual budget appropriations, compliance with regulations, as well as specifications regarding objectives and results. Certain specific contracts include obligations to maintain a minimum level of employment and investment during a certain period. There could be penalties if these objectives are not fulfilled. Other contracts contain penalties for breach of contract, which may result in repayment obligations. Funding related to these contracts is recorded when the conditions required by the contracts are met. The Company’s funding programs are classified under two general categories: funding for research, development and other innovative activities, and capital investments.

Funding for research, development and innovative activities is the most common form of funding that the Company receives. This public funding is recorded as “Other income and expenses, net” in the consolidated statements of income. The funding is recognized ratably as the related costs are incurred once the agreement with the respective governmental agency has been signed and all applicable conditions are met. Other government assistance, such as funding received for industrialization deployment and local economic development in certain regions, are reported as a deduction of cost of sales or other operating expenses according to the nature of the underlying costs eligible to the grants.

French research tax credits (“Crédit Impôt Recherche”) and Italian research tax credits (“Credito d’Imposta Ricerca & Sviluppo”) are deemed to be grants in substance. The French research tax credits are to be paid in cash by the taxing authorities within three years in case they are not deducted from income tax payable during

this period of time. The Italian tax credits are compensated against payroll-related social charges. French and Italian tax credits are reported as a reduction of “Research and development expenses” in the consolidated statements of income.

Capital investment funding is recorded as a reduction of “Property, plant and equipment, net” on the consolidated balance sheets when the Company has incurred the eligible capital expenditures and when all conditions for eligibility have been fulfilled. Advances from capital grants received on capital investments that have not been incurred yet are reported as in the line "Other long-term liabilities" on the consolidated balance sheets. Capital investment funding is recognized in the Company’s consolidated statements of income by offsetting the depreciation charges of the funded assets during their useful lives. The Company also receives funding, which can be recovered through the reduction of various governmental liabilities, including income tax, value-added tax and employee-related social charges.

Funding receivables are reported as non-current assets unless cash settlement features of the receivables evidence that collection is expected within one year. Long-term receivables that do not present any tax attribute or legal restriction are reflected in the consolidated balance sheets at their net present value when the discounting effect is deemed to be significant.

Research and development

Research and developmentResearch and development expenses include costs incurred by the Company, the Company’s share of costs incurred by other research and development interest groups, and costs associated with co-development contracts. Research and development expenses do not include marketing design center costs, which are accounted for as “Selling, general and administrative expenses” in the consolidated statements of income and process engineering, pre-production or process transfer costs which are recorded as “Cost of sales” in the consolidated statements of income. Research and development costs are expensed as incurred. The amortization expense recognized on technologies and licenses purchased by the Company from third parties to facilitate the Company’s research and development activities is reported as “Research and development expenses” in the consolidated statements of income.

Advertising costs

Advertising costsAdvertising costs are expensed as incurred and are recorded as “Selling, general and administrative expenses” in the consolidated statements of income. Advertising expenses for 2023, 2022 and 2021 were $23 million, $18 million and $12 million, respectively.

Start-up and phase-out costs

Start-up and phase-out costsStart-up costs represent costs incurred in the ramp-up phase of the Company's newly integrated manufacturing facilities. The costs of phase-outs are associated with the latest stages of facilities closure when the relevant production volumes become immaterial. Start-up costs and phase-out costs are included in the line “Other income and expenses, net” of the consolidated statements of income.

Investments in equity securities

Investments in equity securities

Investments in equity securities that have readily determinable fair values and for which the Company does not have the ability to exercise significant influence are classified as equity securities measured at fair value through earnings. Changes in the fair value of these securities are reported in the consolidated statements of income within “Other income and expenses, net” when these instruments are held within the Company’s operating activities. Gains and losses arising from changes in the fair value of securities not related to operating activities are presented in the consolidated statements of income as non-operating elements within “Gain (loss) on financial instruments, net” in the period in which they arise. The fair values of quoted equity securities are based on current market prices. If the market for a financial asset is not active or if no observable market price is obtainable, the Company measures fair value by using assumptions and estimates. In measuring fair value, the Company makes maximum use of market inputs and minimizes the use of unobservable inputs.

For investments in equity securities without readily determinable fair values and for which the Company does not have the ability to exercise significant influence, the Company has elected to apply the cost method as a measurement alternative. Under the cost method of accounting, investments are carried at historical cost, less impairment. An impairment loss is recorded when there are identified events or changes in circumstances that may have a significant adverse effect on the value of the investment. Loss is immediately recorded in the consolidated statements of income on the line “Gain (loss) on financial instruments, net” and is based on the Company’s assessment of any significant and sustained reductions in the investment’s value. Gains and losses on investments sold are determined on the specific identification method and are recorded as non-operating element in the line “Gain (loss) on financial instruments, net” of the consolidated statements of income when the transaction is not related to operating activities.

The Company did not hold any material equity securities as of December 31, 2023 and December 31, 2022.

Investments in debt securities

Investments in debt securities

Debt securities are included in current assets when they represent investments of funds available for current operations.

Changes in fair value of debt securities classified as available-for-sale are recognized as a component of “Other comprehensive income (loss)” in the consolidated statements of comprehensive income. The Company assesses at each balance sheet date whether there is objective evidence that a debt security or group of debt securities is impaired. An unrealized impairment loss exists when the fair value of the instrument declines below its amortized cost basis. An impairment loss is recognized in earnings, through a direct reduction of the value of the asset, when the Company intends to sell the debt security or when it is more likely than not that the Company will be required to sell the instrument before recovery of the amortized cost basis. Moreover, an impairment loss is recognized in earnings through a credit loss allowance for any portion of the unrealized impairment loss resulting from a credit loss. Impairment losses recognized in the consolidated statements of income are not reversed through earnings.

The fair values of quoted debt securities are based on current market prices. If the market for a financial asset is not active and if no observable market price is obtainable, the Company measures fair value by using assumptions and estimates. In measuring fair value, the Company makes maximum use of market inputs and minimizes the use of unobservable inputs.

The Company did not hold any debt securities classified as held-to-maturity or for which the Company would have elected to apply the fair value option.

Derivative financial instruments and hedging activities

Derivative financial instruments and hedging activities

Derivative financial instruments are initially recognized on the date a derivative contract is entered into and are subsequently measured at fair value. The method of recognizing the gain or loss resulting from the derivative instrument depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the hedge transaction. The Company has designated certain derivatives as hedges of a particular risk associated with a highly probable forecasted transaction (cash flow hedge).

The Company documents, at inception of the transaction, the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedging transactions. The Company also documents its assessment, both at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items. Derivative instruments that are not designated as hedges are measured at fair value through earnings.

Cash Flow Hedge

As part of its ongoing operating, investing and financing activities, the Company enters into certain derivative transactions that may be designated and may qualify as hedging instruments. To reduce its exposure to U.S. dollar exchange rate fluctuations, the Company hedges certain Euro-denominated forecasted transactions that cover at reporting date a large part of its research and development, and selling, general and administrative expenses as well as a portion of its front-end manufacturing costs of semi-finished goods within cost of sales

through the use of currency forward contracts and currency options, including collars. The Company also hedges through the use of currency forward contracts certain Singapore dollar-denominated manufacturing forecasted transactions.

The derivative instruments are designated and qualify for cash flow hedge at inception of the contract and on an ongoing basis over the duration of the hedge relationship. They are reflected at their fair value as “Other current assets” or “Other payables and accrued liabilities” in the consolidated balance sheets when settlement is expected to occur within twelve months after the reporting date. They are reported as "Other non-current assets" or "Other long-term liabilities" in the consolidated balance sheets when settlement is expected beyond twelve months. The criteria for designating a derivative as a hedge include the instrument’s effectiveness in risk reduction and matching of the derivative instrument to its underlying transactions with the critical terms of the hedging instrument matching the terms of the hedged forecasted transaction. This enables the Company to conclude that changes in cash flows attributable to the risk being hedged are expected to be substantially offset by the hedging instruments.

For derivative instruments designated as cash flow hedge, the change in fair value for the effective portion of the hedge is reported as a component of “Other comprehensive income (loss)” in the consolidated statements of comprehensive income and is reclassified into earnings in the same period in which the hedged transaction affects earnings, and within the same consolidated statements of income line as the hedged transaction. For these derivatives, ineffectiveness appears if the cumulative gain or loss on the derivative hedging instrument exceeds the cumulative change in the expected future cash flows on the hedged transaction. Effectiveness on transactions hedged through purchased options is measured on the full fair value of the option, including time value.

Derivative financial instruments not designated as a hedge

The Company conducts its business on a global basis in various major international currencies. As a result, the Company is exposed to adverse movements in foreign currency exchange rates. The Company enters into foreign currency forward contracts and currency options to reduce its exposure to changes in exchange rates and the associated risk arising from the denomination of certain assets and liabilities in foreign currencies at the Company's subsidiaries.

Financial instruments not designated as a hedge are classified as current assets when they are expected to be realized within twelve months of the balance sheet date. Marked-to-market gains or losses arising from changes in the fair value of these instruments are reported in the consolidated statements of income within “Other income and expenses, net” in the period in which they arise, since the transactions for these instruments occur within the Company’s operating activities.

Recent accounting pronouncements

Recent accounting pronouncements

(a)Accounting pronouncements effective in 2023

No new guidance was adopted in 2023 with a significant impact on the Company's financial statements, financial positions and operations.

(b)Accounting pronouncements expected to impact the Company’s operations that are not yet effective and have not been early adopted by the Company

In November 2023, the FASB issued new guidance related to segment reporting, which requires incremental disclosures about reportable segments, without changing though the definition of a segment or the guidance for determining reportable segments. The new guidance requires disclosures of significant segment expenses that are (i) regularly provided to (or easily computed from information regularly provided to) the chief operating decision maker ("CODM"); (ii) included in the reported measure of segment profit or loss. The new guidance also requires that an entity discloses, on an annual and interim basis, an amount for "other segment items" by reportable segment, and a description of its composition. Moreover, annual disclosures about a reportable segment's profit or loss and assets become mandatory on interim periods. Finally, the title and position of the CODM, together with an explanation of how the CODM uses the reported measures of segment profit or loss in assessing segment performance and deciding how to allocate resources, are also required. The guidance is effective for the Company's 2024 annual reporting and 2025 interim periods. The guidance will be applied retrospectively, with early adoption permitted. The Company will adopt the new guidance when effective and is currently assessing the impact the new guidance will have on its segment reporting.

In December 2023, the FASB issued new guidance related to income taxes, which requires additional disclosures, primarily around disaggregation of income tax paid and specific categories in the income tax rate reconciliation. The guidance is effective for the year ended December 31, 2025, with early adoption permitted. The guidance will be applied prospectively. Retrospective application is permitted. The Company is currently assessing the impact the new guidance will have on its annual income tax disclosures.

– Senior unsecured convertible bonds issued on August 4, 2020 (2)	1	1,496	1,814	1,495	1,561

(1)     Cash equivalents primarily correspond to deposits at call with banks.

(2)     The carrying amount as of December 31, 2023, of the senior unsecured convertible bonds as reported above, corresponds to the nominal value of the bonds, net of $4 million unamortized debt issuance costs. The fair value represented the market price of the bonds trading on the Frankfurt Stock Exchange.

Schedule of Methodologies Used to Estimate Fair Value

The methodologies used to estimate fair value are as follows:

Components	Methodology used to estimate fair value
Debt securities classified as available-for-sale	Quoted market prices for identical instruments
Foreign exchange forward contracts, currency options and collars	Quoted market prices for similar instruments
Equity securities measured at fair value through earnings	Quoted market prices for identical instruments
Equity securities carried at cost as a measurement alternative	Valuation of the underlying investments on a new round of third-party financing or upon liquidation
Long-term debt and current portion of long-term debt	Future cash flows on a borrowing-by-borrowing basis and discounting these future cash flows using the Company's incremental borrowing rates for similar types of borrowing arrangements. For convertible bonds, the fair value represents the market price of the bonds trading on the Frankfurt Stock Exchange
Cash and cash equivalents, short-term deposits, accounts receivable, short-term borrowings, and accounts payable	The carrying amounts reflected in the consolidated financial statements are considered as reasonable estimates of fair value due to the relatively short period of time between the origination of the instruments and their expected realization.
