Our Strategy

The Company’s overall strategy is to provide our customers with comprehensive design capabilities, a broad selection of products and a high level of quality and service on a worldwide basis, while maintaining continuing programs of productivity improvement and cost control. Specifically, our business strategy is as follows:

Pursue broad market diversification - The Company constantly strives to increase the diversity of its markets, customers, applications and products. Due to the tremendous variety of opportunities in the electronics industry, management believes that it is important to participate wherever significant growth opportunities are available. This diversification positions us to proliferate our technologies across the broadest array of opportunities and reduces our exposure to any one particular market, thereby reducing the variability of our financial performance. An overview of the Company’s market and product participation is described under “Markets”.

Develop high-technology performance-enhancing solutions - The Company seeks to expand the scope and number of its preferred supplier relationships with customers across its diverse end markets. The Company works closely with its customers at the design stage to create and manufacture innovative solutions. These products generally have higher value-added content than other interconnect, antenna and sensor products, and have been developed across the Company’s end markets. The Company is focused on technology leadership in the interconnect areas of radio frequency, power, harsh environment, high-speed and fiber optics, as well as antennas and sensors, as it views these technology areas to be of particular importance to our global customer base.

Expand global presence - The Company is strategically expanding and shifting its global manufacturing, engineering, sales and service operations to better serve its existing customer base, penetrate developing markets and establish new customer relationships. As the Company’s global customers have grown their international operations to access developing world markets and lower manufacturing costs, the Company is continuing to expand and shift its international footprint in order to provide real-time capabilities to these customers. The majority of the Company’s international operations have broad capabilities, including new product development. The Company is also able to take advantage of the lower manufacturing costs in some regions, and has established low-cost manufacturing and assembly facilities around the world.

Control costs - The Company recognizes the importance in today’s global marketplace of maintaining a competitive cost structure. Innovation, product quality and performance, and comprehensive customer service are not mutually exclusive with controlling costs. Controlling costs is part of a mindset. It is having the discipline to invest in programs that have a good return, maintaining a cost structure as flexible as possible to respond to changes in the marketplace, working with suppliers and vendors in a fair but prudent way to ensure a reasonable cost for materials and services and creating a mindset where managers manage the Company’s assets as if they were their own. This mindset was particularly important in recent years, as supply chain challenges arose, followed by inflationary pressures and logistical challenges that persisted into 2023.

Pursue strategic acquisitions and investments - The Company believes that the industry in which it operates is highly fragmented and continues to provide significant opportunities for strategic acquisitions. As a result, we continue to pursue acquisitions of high-potential companies with strong management teams that complement our existing business while further expanding our product lines, technological capabilities and geographic presence. We seek to enhance the performance of acquired companies by leveraging Amphenol’s position with customers across our diverse end markets, our leading technologies and our access to low-cost manufacturing around the world. In 2023, the Company invested approximately $970 million to fund 10 acquisitions, while in 2022, the Company invested approximately $288 million to fund two acquisitions. Our acquisitions in 2023 and 2022 have strengthened our customer base and product offerings in many of our end markets and have brought a number of high-performing new management teams into the Company.

Foster collaborative, entrepreneurial management - Amphenol’s management system is designed to provide clear income statement and balance sheet responsibility in a flat organizational structure. Each general manager is enabled and incented to grow and develop their business and to think entrepreneurially in providing innovative, timely and cost-effective solutions to meet customer needs. In addition, Amphenol’s general managers have access to the resources of the larger organization and are encouraged to work collaboratively with their peers throughout the Company to meet the needs of the expanding marketplace and to achieve common goals. As the Company has grown, we have preserved this unique culture of entrepreneurship by ensuring that our executive organization can effectively drive the performance of and collaboration among our global general managers. The alignment of the Company’s businesses into three divisions (representing the Company’s

Customers and Geographies

The Company manufactures and sells a broad portfolio of products on a global basis to customers in a wide variety of industries. Our customers include many of the leaders in their respective industries, and our relationships with them typically date back many years. We believe that our diversified customer base provides us with the opportunity to leverage our skills and experience across markets and reduces our exposure to particular end markets. Additionally, we believe that the diversity of our customer base is an important asset of the Company.

For many years, customers have generally been consolidating their lists of qualified suppliers to companies that have the ability to meet certain technical, quality, delivery and other standards while maintaining geographic flexibility and competitive prices. The Company has positioned its global resources to compete effectively in this environment. As an industry leader, the Company has established close working relationships with many of its customers on a global basis. These relationships allow the Company to better anticipate and respond to these customer needs when designing new products and new technical solutions. By working with customers to develop new products and technologies, the Company is able to identify and act on trends and leverage knowledge about next-generation technology across our portfolio of products. In addition, the Company has concentrated its efforts on service, procurement and manufacturing improvements designed to increase product quality and performance and lower product lead-time and cost. For a discussion of certain risks related to the Company’s sales, refer to the subsection titled “Risks Related to our End Markets” included in Part I, Item 1A. Risk Factors herein.

The Company’s products are sold to thousands of original equipment manufacturers (or OEMs) in numerous countries throughout the world. The Company’s products are also sold to electronic manufacturing services (EMS) companies, to original design manufacturers (or ODMs) and to service providers, including telecommunications network service providers and web service providers. No single customer accounted for 10% or more of the Company’s net sales during the years ended December 31, 2023, 2022 and 2021.

The Company sells its products through its own global sales force, independent representatives and a global network of electronics distributors. The Company’s sales to distributors represented approximately 17% and 18% of the Company’s net sales in 2023 and 2022, respectively.

The Company designs, manufactures and assembles its products at facilities in approximately 40 countries around the world. Our global coverage positions us near many of our customers’ locations and allows us to assist them in consolidating their supply base and lowering their production and logistics costs. In addition, the Company generally relies on local management in every region, which we believe creates a strong degree of organizational stability and operational agility, as well as a deeper understanding of local markets. We believe our broad and balanced geographic distribution lowers our exposure to particular geographies. This was evident in recent years, as we were generally able to support our customers even if pandemic-related restrictions and other challenges were present in a particular geography. The Company believes that its global presence is an important competitive advantage, as it allows the Company to provide quality products on a timely and worldwide basis to its multinational customers, while at the same time offering a level of resiliency and diversification against local risks and challenges that may emerge in any single geography.

The Company employs a global manufacturing strategy to provide proximity and reliable service to customers, while also lowering production and logistics costs. Our strategy is to maintain strong cost and quality controls in our manufacturing and assembly operations. The Company evaluates and adjusts its expense levels and workforce to reflect current business conditions and attempts to maximize operating profitability as well as the return on capital investments. This strategy has been, and continues to be, critical to the Company’s ability to mitigate supply chain constraints, such as those experienced in recent years, and the higher inflationary environment, which began in 2022 and persisted into 2023. The Company sources its products on a worldwide basis. To better serve certain high-volume customers, the Company has established certain facilities near these major customers. The Company seeks to position its manufacturing and assembly facilities in order to serve local markets while coordinating, as appropriate, product design and manufacturing responsibility with the Company’s other operations around the world.

Trademark rights may potentially extend for longer periods of time and are dependent upon the laws of various jurisdictions and the use of the trademarks.

We also rely upon trade secrets, manufacturing know-how, continuing technological innovations and licensing opportunities to maintain and improve our competitive position. We review third-party proprietary rights, including patents and patent applications, as available, in an effort to develop an effective intellectual property strategy, avoid infringement of third-party proprietary rights, identify licensing opportunities and monitor the intellectual property claims of others.

From time to time, the Company is involved in disputes with third parties regarding the Company’s or such third party’s intellectual property assets, particularly patents. While we consider our patents and trademarks to be valuable assets, we do not believe that our competitive position or our operations are dependent upon or would be materially impacted by the loss of any single patent or group of related patents, or by a third party’s successful enforcement of its

8

The Company also purchases a wide variety of mechanical and electronic components for the manufacturing of its products. Such raw materials and components are generally available throughout the world and are purchased locally from a variety of suppliers. The Company is generally not dependent upon any one source for raw materials or components or, if one source is used, the Company generally attempts to protect itself through long-term supply agreements. From time to time, the Company may encounter difficulties in obtaining certain raw materials or components necessary for production due to supply chain constraints and logistical challenges, which may include regulatory restrictions. These difficulties may also negatively impact the pricing of materials and components sourced or used by the Company. While the Company does not currently anticipate significant, broad-based difficulties in obtaining raw materials or components necessary for production, inflationary pressures and logistical challenges may impact the cost and availability of certain raw materials and components used by the Company and result in supply shortages for discrete raw materials or components, which could be further exacerbated by increased commodity prices and additional inflation. For a discussion of certain risks related to the availability of and dependence on raw materials and components, refer to the risk factor titled “The Company and certain of its suppliers and customers have experienced difficulties obtaining certain raw materials and components, and the cost of certain of the Company’s raw materials and components is increasing” in Part I, Item 1A. Risk Factors herein. Information regarding our obligations related to commitments to purchase certain goods and services is disclosed in Note 14 of the Notes to Consolidated Financial Statements.

Competition

The Company encounters competition in all areas of its business. The Company competes primarily on the basis of technology innovation, product quality and performance, price, customer service and delivery time. Primary competitors include Aptiv, Belden, Commscope, Eaton, Foxconn, Glenair, HARTING, Hirose, HUBER+SUHNER, ICT Luxshare, JAE, Jonhon, JST, Molex, Phoenix Contact, Radiall, Rosenberger, Sensata, TE Connectivity, Yazaki and 3M, among others. In addition, the Company competes with a large number of smaller companies who compete in specific geographies, markets or products. For a discussion of certain risks related to competition, refer to the risk factor titled “The Company encounters competition in all areas of our business” in Part I, Item 1A. Risk Factors herein.

Backlog and Seasonality

The Company estimates that its backlog of unfilled firm orders as of December 31, 2023 was approximately $4.0 billion compared with backlog of approximately $4.1 billion as of December 31, 2022. Orders typically fluctuate from quarter to quarter based on customer demand and general business conditions. Unfilled orders may generally be cancelled prior to shipment of goods. It is expected that nearly all of the Company’s backlog will be filled within the next 12 months. A significant portion of the Company’s business, such as sales to the communications-related markets (including wireless communications, information technology and data communications and broadband communications) and sales to distributors, generally have short lead times. Therefore, backlog may not be indicative of future demand. Generally, the Company does not experience significant seasonality in its business, although historically, the strongest quarters have typically been the last two quarters of our fiscal year.

Environmental Matters

Certain operations of the Company are subject to environmental laws and regulations that govern the discharge of pollutants into the air and water, as well as the handling and disposal of solid and hazardous wastes. The Company believes that its operations are currently in substantial compliance with applicable environmental laws and regulations and that the costs of continuing compliance will not have a material adverse effect on the Company’s financial condition, results of operations or cash flows. For more information on certain environmental matters, refer to Note 14 of the Notes to Consolidated Financial Statements. For a discussion of certain risks related to environmental matters, refer to

the risk factor titled “The Company is subject to environmental laws and regulations that could adversely affect our business” in Part I, Item 1A. Risk Factors herein.

Government Regulation

As a global company, we are subject to various laws and regulations applicable to parties doing business with the U.S. and other governments, including laws and regulations governing reporting obligations, interactions with government officials, performance of government contracts, the use and treatment of government furnished property and the nature of materials used in our products. In addition, the Company and its products are subject to import and export regulations present in each of the various jurisdictions in which we operate around the world. Certain of our products, including purchased components of such products, are subject to U.S. and non-U.S. export control laws and regulations, and may be exported only with the required export license or through an export license exception. The issuances of such licenses, in particular within the defense market, are subject to complex laws and regulations that could change frequently and with limited notice, depending on the jurisdiction, geopolitical events or other factors. The Company has systems in place to apply for licenses and to maintain compliance with any such regulations. Separately, we are required to comply with certain U.S. and non-U.S. economic sanctions and trade embargoes, as well as the terms of any preferential duty and/or tariff programs in which we participate.

For a discussion of certain risks related to government regulation, including export and import controls and sanctions, refer to the risk factors titled “The Company is exposed to political, economic, military and other risks related to operating in countries outside the United States, and changes in general economic conditions, geopolitical conditions, U.S. trade policies and other factors beyond the Company’s control may adversely impact its business and operating results,” “The Company must comply with complex U.S. governmental export and import controls as well as economic sanctions and trade embargoes,” “Our business and financial results may be adversely affected by government contracting risks,” and “Our international operations require us to comply with anti-corruption laws and regulations of the U.S. government and various foreign jurisdictions, and our business reputation and financial results may be impaired by improper conduct by any of our employees, customers, suppliers, distributors or any other business partners,” in Part I, Item 1A. Risk Factors herein.

Environmental, Social and Corporate Governance

We have a shared commitment to create innovative products and enable technologies that improve the lives of people around the world, to support the well-being of our employees and communities and to sustain the health of our planet. We believe that long-term value for our Company is created through making sustainable business choices, building strong relationships with our stakeholders and engaging in good corporate governance. Whether through reducing our and our partners’ environmental footprint, following humane labor practices, supporting the development and diversity of our global team, ensuring the strength and integrity of our supply chain or giving back to our communities, we have always believed that it is not just good stewardship, but good business to focus on the long-term sustainability of Amphenol.

Sustainability Report

The Company publishes an annual sustainability report (“Sustainability Report”) to highlight our goals and areas of progress and success in sustainability matters, including climate-related topics. The Sustainability Report discusses our approach and progress on the environmental, social and governance (“ESG”) issues most significant to our business, including ESG-related strategies, programs, goals and metrics that demonstrate our commitment to our stakeholders. The Sustainability Report is designed to inform and engage the Company’s broad range of stakeholders, such as employees, suppliers, customers, community members and investors, among others. Our 2022 Sustainability Report was prepared with reference to the Global Reporting Initiative (“GRI”) Standards framework and topics identified under the Sustainability Accounting Standards Board (“SASB”) standards and outlines board and executive-level oversight of climate-related risks and opportunities identified in the Task Force on Climate-Related Financial Disclosures (“TCFD”) recommendations. The SASB standards and GRI and TCFD frameworks encourage companies to disclose climate-related topics that are important to certain interested stakeholders, even if not material for purposes of the U.S. securities laws. Furthermore, the materiality standards under these frameworks are different from the materiality standard under the U.S. securities laws. Our 2022 Sustainability Report is available on our website at https://amphenol.com/sustainability. The items discussed in our 2022 Sustainability Report have not required material capital expenditures or operating expenses, nor caused material operational challenges or risks to the Company’s business or results of operations beyond those items disclosed in Item 1A. Risk Factors within the risk factors titled “The

Company may be negatively impacted by extreme weather conditions and natural catastrophic events, including those caused or intensified by climate change and global warming,” “The Company is subject to, and may continue to be subject to, incremental costs, risks and regulations associated with efforts to combat the negative effects of climate change,” and “Increasing scrutiny and expectations regarding ESG matters could result in additional costs or risks or otherwise adversely impact our business”. Information included in our 2022 Sustainability Report and our website is not incorporated by reference in, and does not form part of, this Annual Report. Our 2023 Sustainability Report is expected to be released during the second quarter of 2024.

Human Capital Management and Our Culture

The Company’s success is closely tied to the capability, adaptability and accountability of our diverse, global organization. One of the key components of our business strategy is the fostering of a collaborative and entrepreneurial management culture. Each of our general managers operates in a flat organizational structure and is enabled and incented to grow and develop their business, with the support of the resources of the larger organization. We believe this structure, with approximately 130 general managers running unique, independent businesses, creates an environment and culture where each of our general managers has a more direct link to the success of their individual businesses and a more personal connection to the employees they oversee and the communities in which they operate.

As of December 31, 2023, the Company had approximately 95,000 employees worldwide, of which approximately 11,000 were located in the United States. Less than 10% of Amphenol’s U.S. workforce is represented by an independent trade union or covered by collective bargaining. The Company believes that it has a good relationship with both its unionized and non-unionized employees.

Governance and Culture – Our Board of Directors (the “Board”) is actively involved in overseeing the Company’s employee-related strategies and practices as well as the Company’s culture and ESG initiatives. This oversight is conducted both directly and through certain of the Board’s committees. At each of its regularly scheduled quarterly meetings, the Board reviews changes in key personnel and, at least once a year, meets with management to discuss various human resources related topics, including talent development, succession planning, diversity, equity and inclusion initiatives, compensation and culture. We believe the Company’s culture has been a critical component of the Company’s success and reinforcing that culture is a key responsibility of our executive management.

Diversity, Equity and Inclusion – Amphenol is committed to workplace diversity and fostering a culture of equity, inclusion and belonging across our organization. Our business spans the globe, and the employees in our facilities reflect the diversity of the communities in which we operate. At Amphenol, we promote and maintain a culture of respect and appreciation of differences in our employees. The Company generally relies on local management in every business unit to foster a culture of diversity, equity and inclusion, which we believe creates a strong degree of organizational stability and a deep commitment to our people and the local community. A key hallmark of our structure is our entrepreneurial culture that creates clear accountability for each of our general managers, who are our key business leaders. Our core management team is comprised of these general managers and their controllers, as well as our group general managers and executive management team. Women represented 26% of this core management team at the end of 2023. Of our total employees worldwide, approximately half are women.

Health, Safety and Well-being – We believe that the protection of our employees is a moral obligation. In addition, the safety and well-being of our employees is critical to the successful operation of our business. Our health and safety activities are overseen by our corporate environmental, health, safety and sustainability leadership team and are managed by our local teams, who coordinate on-site safety programs, resources, reporting and training in our facilities. We believe that this model of coaching and tracking at the corporate level, but administering at the facility level, has allowed us to provide training and supervision that better fits the local needs of each of our workforces.

Compensation and Benefits – The Company is focused on providing our employees around the world equitable and competitive compensation and benefits. In the U.S., in addition to competitive compensation, the Company maintains various employee benefits such as health and related insurance, retirement savings programs and health savings and flexible spending accounts. Outside the U.S., we maintain compensation and other benefits competitive with local market conditions.

Community and Social Impact – Amphenol recognizes that we have a responsibility to be a positive influence in the communities in which we operate around the world. Most of our community outreach is organized by our local management teams, which helps ensure that our efforts are working in support of the local communities in which our

11

Table of Contents

employees live and work. Our local teams are actively supporting their communities in a variety of ways including: school supply drives, local blood drives, mentoring of at-risk students, community clean-up events, local tree planting, holiday-giving events and food delivery services.

Item 1A. Risk Factors

The Company’s business, operations, financial condition, liquidity, results of operations and stock price can be negatively affected by many risk factors. Investors should carefully consider the risks described below and all other information in this Annual Report. The Company’s past financial performance, including historical trends, should not be considered a reliable indicator of future performance. The risks and uncertainties described below are not the only ones facing the Company. Additional risks and uncertainties not presently known to the Company or that we currently consider immaterial may materialize and impair the Company’s business, operations, financial condition, liquidity, results of operations and/or stock price.

If actions taken by management to limit, monitor or control enterprise risk exposures are not successful, the Company’s business, operations, financial condition, liquidity and results of operations could be materially adversely affected. In such case, the trading price of the Company’s Common Stock and debt securities could decline and investors may lose all or part of their investment.

RISKS RELATED TO OUR GLOBAL OPERATIONS

The Company is exposed to political, economic, military and other risks related to operating in countries outside the United States, and changes in general economic conditions, geopolitical conditions, U.S. trade policies and other factors beyond the Company’s control may adversely impact its business and operating results.

The Company’s operations and performance depend significantly on global, regional and U.S. economic and geopolitical conditions. During 2023, non-U.S. markets constituted approximately 65% of the Company’s net sales, with China constituting approximately 23% of the Company’s net sales. The Company employs nearly 90% of its workforce outside the United States. The Company’s customers are located throughout the world, and the Company has many manufacturing, administrative and sales facilities outside the United States.

During the last few years there have also been significant changes to U.S. trade policies, sanctions, legislation, treaties and tariffs, including, but not limited to, trade policies and tariffs affecting China. These changes have, in certain cases, increased our costs of doing business. The imposition of additional tariffs or other trade barriers could increase our costs in certain markets and may cause our customers to find alternative sourcing or could make it more difficult for us to sell our products in some markets. Other countries where we operate or sell our products have changed, and may continue to change, their own policies on trade as well as business and foreign investment in their respective countries. For example, we have manufacturing facilities in certain jurisdictions that are authorized to operate under preferential duty and/or tariff programs that provide for reduced tariffs and/or eased import and export regulations and are subject to compliance with the terms of such programs, which have become stricter. Failure to comply with the terms of such programs could increase our manufacturing costs and adversely affect our business, operating results and financial condition. Additionally, it is possible that U.S. policy changes and uncertainty about such changes could increase market volatility and currency exchange rate fluctuations. As a result of these dynamics, we cannot predict the

12

Table of Contents

impact to our business of any future changes to the U.S.’s or other countries’ trading relationships or the impact of new laws or regulations adopted by the U.S. or other countries.

In addition to the risks noted above, a number of other legal, economic and geopolitical factors both in the United States and abroad could have a material adverse effect on the Company’s business, operations, financial condition, liquidity and/or results of operations, such as:

a global or regional economic slowdown or recession in any of the Company’s end markets (or a prolonging or intensification of such a slowdown or recession), which could negatively affect the financial condition of our customers and result in reduced demand;
postponement of customer spending, in response to tighter credit, inflationary pressures, financial market volatility and other global economic factors;
effects of significant changes in economic, monetary and/or fiscal policies in the United States and/or abroad, including interest rate changes by the U.S. Federal Reserve or other international central banking systems, foreign currency fluctuations, significant income tax changes and inflationary pressures;
intergovernmental and other conflicts or actions, including, but not limited to, armed conflict, such as the ongoing military conflicts between Ukraine and Russia as well as Israel and Hamas, trade wars, cyberattacks and acts of terrorism or war;
employment regulations and local labor conditions, including increases in employment costs, particularly in low-cost regions in which the Company currently operates;
industrial policies in various countries that favor domestic industries over multinationals or that restrict foreign companies altogether;
difficulties protecting intellectual property;
longer payment cycles;
changes in exchange control regulations, including any government actions that prohibit, limit or increase the cost of paying a dividend or otherwise moving cash between the Company’s subsidiaries located in different countries;
credit risks and other challenges in collecting accounts receivable; and
changes in assumptions, such as discount rates, along with lower than expected investment returns and performance related to the Company’s benefit plans.

We may be negatively impacted by adverse public health developments, including epidemics and pandemics.

Any outbreaks of contagious diseases and other adverse public health developments in countries where we operate could have a material and adverse effect on our business, operations, financial condition, liquidity and results of operations. Beginning in early 2020 and continuing through 2022, the COVID-19 pandemic disrupted our offices and manufacturing facilities around the world, as well as the facilities of our suppliers, customers and our customers’ contract manufacturers. These disruptions included government regulations that inhibited our ability to operate certain of our facilities in the ordinary course, travel restrictions, supplier constraints, supply chain interruptions, logistics challenges and limitations, labor disruptions and reduced demand from certain customers. Future disruptions from similar harmful public health developments could have a material adverse impact on our business, operations, financial condition, liquidity and results of operations.

The Company and certain of its suppliers and customers have experienced difficulties obtaining certain raw materials and components, and the cost of certain of the Company’s raw materials and components is increasing.

The Company uses basic materials like aluminum, steel, copper, titanium, metal alloys, gold, silver, palladium and plastic resins in its manufacturing processes as well as a variety of components and relies on third-party suppliers to secure these materials and components. While the Company does not currently anticipate significant, broad-based difficulties in obtaining raw materials or components necessary for production, inflationary pressures and logistical challenges may impact the cost and availability of certain raw materials and components used by the Company and result in supply shortages for discrete raw materials or components, which could be further exacerbated by increased commodity prices and additional inflation. Moreover, the Company may not be able to pass along any increased raw material or component prices to its customers and may not be able to procure and obtain sufficient quantities of raw materials and components timely and at acceptable prices from our suppliers. In limited instances, we depend on a single source of supply or participate in commodity markets that may be served by a limited number of suppliers. Delays in obtaining supplies may result from a number of factors affecting our suppliers, and any delay could impair our

13

Table of Contents

ability to deliver products to our customers. The cost and availability of raw materials may fluctuate significantly due to external factors including, but not limited to, product scarcity, war or other armed conflict, logistical challenges, disruptions caused by climate change and adverse weather conditions, commodity market fluctuations, currency fluctuations, governmental policies and regulations such as trade tariffs and import restrictions, as well as pandemics and epidemics (as was the case with the COVID-19 pandemic), which may, in turn, negatively impact our results of operations and financial condition.

Cybersecurity incidents affecting our information technology systems could disrupt business operations or cause the release of highly sensitive confidential or personal information, resulting in adverse impacts to our reputation and operating results and potentially leading to litigation and/or governmental investigations, fines and other penalties.

We rely on our information technology systems for critical operations and face numerous and evolving cybersecurity threats and techniques used to disrupt operations and gain unauthorized access to these systems. These threats may arise from diverse threat actors such as state-sponsored organizations and opportunistic hackers and hacktivists, as well as through diverse attack vectors, including, but not limited to, malware, social engineering/phishing, credential harvesting, ransomware, malfeasance by insiders, human or technological error and other increasingly sophisticated attacks. Cyberattacks continue to expand and evolve, making it difficult to detect and prevent such threats from impacting the Company. Globally, there continues to be an increased volume of cyber threats, ransomware attempts and social engineering attacks, such as phishing and impersonation, and attackers increasingly use tools and techniques that are designed to circumvent controls, avoid detection, and remove or obfuscate forensic evidence. In addition, the rise of artificial intelligence and machine learning has led to more sophisticated and deceptive attacks. Attackers can manipulate systems in new ways and more easily perform functions at scale. As a result, we may be unable to detect, investigate, remediate, or recover from future attacks or incidents, or avoid a material adverse impact to our business.

In addition, global remote working dynamics continue to present additional risk that threat actors will engage in social engineering (for example, phishing) and exploit vulnerabilities in corporate and non-corporate networks. Ransomware attacks have become easier to execute, and with the rise of ransomware as a service, it has become an increasingly popular business model to lease or sell ransomware variants to anyone willing to pay the fee.

There can be no assurance that our cybersecurity risk management program and processes, including our policies, controls or procedures, will be fully complied with or effective in protecting our information technology systems. The Company and third-party providers upon whom we may rely for certain information technology services have been, and expect to continue to be, a target of various cybersecurity attacks, including, but not limited to, ransomware attacks. While the impact of such attacks has not been material, future cybersecurity incidents could lead to unauthorized access to and potentially impair the Company’s information technology systems, products, customers, suppliers and third-party service providers. Cybersecurity incidents could potentially result in the disruption of our business operations and/or misappropriation, destruction or corruption of critical data and confidential, personal, or proprietary information. Cybersecurity events could also result in the loss of or inability to access confidential information and critical business, financial or other data, and/or cause the release of highly sensitive confidential or personal information. Cybersecurity incidents could also result from unauthorized parties gaining access to our systems or information through fraudulent or other means of deceiving our employees, suppliers or third-party service providers. Our and key third-party information technology systems and infrastructure are susceptible to disruptions from cybersecurity incidents, ransomware attacks, security breaches, computer viruses, security vulnerabilities or “bugs” in software or hardware, outages, systems failures, natural disasters, adverse public health developments, or other catastrophic events, any of which could result in reputational damage that may cause the loss of existing or future customers, the loss of our intellectual property, the release of highly sensitive confidential or personal information, the inability to access critical data and other operational disruptions, litigation with third parties (including class actions) and/or governmental investigations and fines, among other things, which could have a material adverse effect on our business, financial condition and results of operations. Finally, we cannot guarantee that any costs and liabilities incurred in relation to an attack or incident will be covered by our existing insurance policies or that applicable insurance will be available to us in the future on economically reasonable terms or at all.

We and our business partners maintain significant amounts of data electronically in locations around the world.  This data relates to all aspects of our business, including financial information and current and future products under development, and also contains certain customer, supplier, partner and employee data, such as personal information. There is a risk of intrusion, cyberattacks or tampering that could compromise the integrity and privacy of this data or make the data inaccessible to us. In addition, in certain cases, in order to conduct business, we outsource to

14

Table of Contents

third-party business partners. Those partners may also be subject to data intrusion or a cyberattack. Any compromise of the data could substantially disrupt our operations, impact future business opportunities, harm our customers, employees and other business partners, damage our reputation, violate applicable laws, regulations, policies and contractual obligations and subject us to potentially significant costs and liabilities, including litigation or other enforcement actions.

The regulatory environment surrounding information security and privacy is increasingly demanding, with frequent imposition of new and changing requirements. Privacy laws and regulations around the world including, for example, in the European Union (“EU”), People’s Republic of China, the state of California, and several other U.S. states, impose significant obligations for companies on how they collect, store, protect, process and transfer personal information and can impose significant fines for non-compliance. In addition, in March 2022, the U.S. enacted the Strengthening American Cybersecurity Act, which imposes cyber incident and ransomware attack response protocols for businesses operating in numerous core industry sectors of the U.S. economy. The potential for fines, penalties, and other related costs in the event of a breach of or non-compliance with any existing and forthcoming information security or privacy laws and requirements may have an adverse effect on our financial results. For further discussion of the Company’s risk management, strategy, and governance around cybersecurity, refer to Part I, Item 1C. Cybersecurity herein.

The Company may be negatively impacted by extreme weather conditions and natural catastrophic events, including those caused or intensified by climate change and global warming.

From time to time, extreme weather conditions and natural disasters have negatively impacted, and may continue to negatively impact, portions of our operations, as well as the operations of our suppliers, vendors, customers and distributors. Such unpredictable weather conditions and natural disasters including, but not limited to, severe storms, earthquakes, fires, droughts, floods, hurricanes, tornadoes, and stronger and longer-lasting weather patterns, including heat waves and freezes and ambient temperature or precipitation changes, and their consequences and effects have, in the past, temporarily disrupted our business operations both in the United States and abroad. These events could cause some of the Company’s operations to suffer from supply chain disruptions and potential delays in fulfilling customer orders or order cancellations altogether, lost business and sales, increased costs, energy and water scarcity, changing costs or availability of insurance, and/or property damage or harm to our people, each and all of which could have an adverse effect on our business, operations, financial condition and results of operations.

Increasing scrutiny and expectations regarding ESG matters could result in additional costs or risks or otherwise adversely impact our business.

Companies across industries continue to face increasing scrutiny from a variety of stakeholders related to their ESG and sustainability practices. Expectations regarding voluntary and potential mandatory ESG initiatives and disclosures may result in increased costs, changes in demand for certain products, enhanced compliance or disclosure obligations, or other adverse impacts to our business, financial condition or results of operations. In addition, an inability to receive or maintain favorable ESG ratings could negatively impact our reputation or impede our ability to compete as effectively to attract and retain employees or customers, which may adversely impact our operations. Unfavorable ESG ratings could also lead to increased negative investor sentiment towards us or our industry, which could negatively impact the share price of our Common Stock as well as our access to and cost of capital.

Our international operations require us to comply with anti-corruption laws and regulations of the U.S. government and various foreign jurisdictions, and our business reputation and financial results may be impaired by improper conduct by any of our employees, customers, suppliers, distributors or any other business partners.

Doing business on a worldwide basis requires us and our subsidiaries to comply with the laws and regulations of the U.S. government and various foreign jurisdictions, and our failure to comply with these rules and regulations may expose us to significant liabilities. These laws and regulations may apply to companies, individual directors, officers, employees, subcontractors and agents, and may restrict our operations, trade practices, investment decisions and partnering activities. In particular, our international operations are subject to U.S. and foreign anti-corruption laws and regulations, such as the Foreign Corrupt Practices Act of 1977, as amended (“FCPA”). As part of our business, we deal with state-owned business enterprises, the employees and representatives of which may be considered foreign officials for purposes of the FCPA. In addition, some of the foreign locations in which we operate lack a developed legal system and have elevated levels of corruption. As a result of the above activities, we are exposed to the risk of violating U.S. and foreign anti-corruption laws.

15

Table of Contents

There can be no assurance that our policies and procedures designed for complying with applicable U.S. and international laws and regulations will be effective in preventing our directors, officers, employees, subcontractors and agents from taking actions that violate these legal requirements. Violations of these legal requirements could subject us to criminal fines and imprisonment, civil penalties, disgorgement of profits, injunctions, debarment from government contracts and other remedial measures. In addition, any actual or alleged violations could disrupt our operations, cause reputational harm, involve significant management distraction and result in a material adverse effect on our competitive position, results of operations, cash flows or financial condition.

The Company’s results can be positively or negatively affected by changes in foreign currency exchange rates.

The Company conducts business in many foreign currencies through its worldwide operations, and as a result, is subject to foreign exchange exposure due to changes in exchange rates of the various currencies, including possible foreign currency restrictions and/or devaluations. Changes in exchange rates can positively or negatively affect the Company’s sales, operating margins and equity. There can be no assurance that any or all actions taken by the Company to mitigate currency risk, such as locating factories in the same country or region in which products are sold, hedging contracts, cost reduction and pricing actions or working capital management, will be fully effective in successfully managing currency risk. A significant and sudden decline in the value of any of the foreign currencies of the Company’s worldwide operations could have an adverse effect on the Company’s business, financial condition, results of operations and cash flows.

The Company is dependent on attracting, recruiting, hiring and retaining skilled employees, including our various management teams.

Our performance is dependent on our ability to attract, recruit, hire and retain skilled personnel, including our executive and core management teams. Given the current inflationary wage environment and strong demand for skilled labor in many of the countries and regions in which we operate, the ability to identify and attract new talent, as well as retain existing talent, may prove to be difficult. It is possible that the current labor market could have an adverse effect on our ability to attract, recruit, hire and retain skilled employees, which in turn, could have an adverse effect on the Company’s business, financial condition and results of operations. In addition, our business could also be adversely impacted by the ongoing increases in labor costs, including wages and benefits.

RISKS RELATED TO OUR END MARKETS

The Company encounters competition in all areas of our business.

The Company competes primarily on the basis of technology innovation, product quality and performance, price, customer service and delivery time. Competitors include large, diversified companies, some of which have greater assets and financial resources than the Company, as well as medium- to small-sized companies. Rapid technological changes could also lead to the entry of new competitors of various sizes against whom we may not be able to successfully compete. There can be no assurance that the Company will be able to compete successfully against existing or new competition, and the inability to do so may result in price reductions, reduced margins, or loss of market share, any of which could have an adverse effect on the Company’s business, financial condition and results of operations.

The Company is dependent on end market dynamics to sell its products, particularly in the communications, automotive and defense end markets.

The Company is dependent on end market dynamics to sell its products, and its operating results could be adversely affected by cyclical and reduced demand in any of these markets. Approximately 37% of the Company’s 2023 net sales came from sales to the communications industry. Demand for products in these markets is generally subject to rapid technological change and/or capital spending by operators for constructing, rebuilding or upgrading their systems, all of which could be affected by a variety of factors, including general economic conditions, consolidation within the industry, the financial condition of operators and their access to financing, competition, technological developments, new legislation and regulation. Approximately 23% of the Company’s net sales came from the automotive industry. The automotive industry has historically experienced significant downturns during periods of deteriorating global or regional economic or credit conditions, or as a result of prolonged work stoppages or other disputes with labor unions. The communications and automotive end markets are also dominated by large customers that regularly exert price pressures on their suppliers, including the Company. Approximately 11% of the Company’s net sales came from sales to the defense end market. Accordingly, the Company’s sales are affected by changes in the defense budgets of the U.S. and

16

Table of Contents

foreign governments, which are subject to political and budgetary fluctuations and constraints. Periodic downturns in any of our customers’ end markets can significantly reduce demand for certain of our products, which could have a material adverse effect on the Company’s business, financial condition and results of operations.

RISKS RELATED TO ACQUISITIONS

The Company has at times experienced difficulties and unanticipated expenses in connection with purchasing and integrating newly acquired businesses.

The Company has completed numerous acquisitions in recent years, including 10 in 2023. The Company anticipates that it will continue to pursue acquisition opportunities as part of its growth strategy. From time to time, the Company experiences difficulty and unanticipated expenses associated with purchasing and integrating acquisitions, and acquisitions do not always perform and deliver the financial benefits expected. The Company has also experienced challenges at times following the acquisition of a new company or business, including, but not limited to, managing the operations, manufacturing facilities and technology; maintaining and increasing the customer base; or retaining key employees, suppliers and distributors. In certain limited cases, the Company has pursued indemnification claims against seller(s) of an acquired business or sought recovery under third party insurance policies for pre-acquisition liabilities, breaches of representations, warranties or covenants or for other reasons provided for in the relevant acquisition agreement or insurance policy. To the extent we pursue indemnification claims against such seller(s) or insurers, such seller(s) or insurers may successfully contest such claims and/or may not have the financial capacity to compensate us for such claims, or such claims may otherwise be difficult or impractical to enforce. We cannot predict or guarantee whether and to what extent anticipated cost savings, benefits, margin improvements and growth prospects will be achieved from recent or future acquisitions.

The Company may in the future incur goodwill and other intangible asset impairment charges.

On December 31, 2023, the total assets of the Company were $16.5 billion, which included $7.1 billion of goodwill (the excess of fair value of consideration paid over the fair value of net identifiable assets of businesses acquired) and $834.8 million of other intangible assets, net. The Company performs annual evaluations (or more frequently, if necessary) for the potential impairment of the carrying value of goodwill and other intangible assets. Such evaluations to date have not resulted in the need to recognize an impairment. However, if the financial performance of the Company’s businesses were to decline significantly, the Company could incur a material non-cash charge to its income statement for the impairment of goodwill and other intangible assets. Furthermore, we cannot provide assurance that impairment charges in the future will not be required if the expected cash flow estimates as projected by management do not occur, especially if an economic recession occurs and continues for a lengthy period or becomes more severe, or if acquisitions and investments made by the Company fail to achieve expected returns.

RISKS RELATED TO OUR LIQUIDITY AND CAPITAL RESOURCES

The Company’s credit agreements and senior notes contain certain requirements, which if breached, could have a material adverse effect on the Company.

The second amended and restated credit agreement that governs our $2.5 billion unsecured credit facility (the “Revolving Credit Facility”), which also backstops the Company’s U.S. commercial paper program (“U.S. Commercial Paper Program”) and Euro commercial paper program (“Euro Commercial Paper Program”), contains financial and other covenants, such as a limit on the ratio of debt to earnings before interest, taxes, depreciation and amortization, a limit on priority indebtedness and limits on incurrence of liens. The Company also has similar financial and other covenants associated with its two-year, $750.0 million unsecured delayed draw term loan credit agreement (the “Term Loan”) entered into in April 2022. In addition, the ability to meet the financial covenants can be affected by events beyond the Company’s control, and the Company cannot provide assurance that it will meet those tests. A breach of any of these covenants could result in a default under the Revolving Credit Facility and the Term Loan. Upon the occurrence of an event of default under the Revolving Credit Facility or the Term Loan, the lenders could terminate all commitments to extend further credit and elect to declare amounts outstanding thereunder to be immediately due and payable, which could result in the acceleration of certain of the Company’s other indebtedness and the Company not having sufficient assets to repay indebtedness under the Revolving Credit Facility, the Term Loan and such other debt instruments. As of December 31, 2023, the Company had no borrowings outstanding under the Revolving Credit Facility, Term Loan, U.S. Commercial Paper Program and Euro Commercial Paper Program. However, the Company borrowed under the U.S.

17

Table of Contents

Commercial Paper Program throughout much of 2023, and the Company may make additional borrowings under any of its debt instruments from time to time.

In addition to these credit agreements, the Company’s various senior notes also impose certain obligations on the Company and prohibit various actions by the Company unless it satisfies certain financial requirements. While the Company is compliant with all such requirements as of December 31, 2023, there can be no assurance that the Company will remain in compliance with such requirements.

The Company relies on the global capital markets, and an inability to access those markets on favorable terms could adversely affect the Company’s results.

The Company has used the global capital markets to raise capital to invest in its business and make strategic acquisitions. The capital and credit markets have experienced significant volatility in the past. If general economic and capital market conditions deteriorate significantly, it could become more difficult to access capital to finance capital investments, acquisitions and other initiatives including dividends and share repurchases, which could have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows. In addition, if the credit rating agencies that rate the Company’s debt were to downgrade the Company’s credit rating, it would likely increase the Company’s cost of capital and make it more difficult for the Company to obtain new financing and access capital markets, which could also have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

The Company’s results may be negatively affected by changing interest rates.

The Company is subject to interest rate volatility with regard to existing and future issuances of debt. The Company monitors its mix of fixed-rate and variable-rate debt, as well as its mix of short-term and long-term debt. As of December 31, 2023, less than 1% of the Company’s outstanding borrowings were subject to floating interest rates.

As a result of increases in the federal funds rate by the U.S. Federal Reserve beginning in early 2022 and through the middle of 2023, the floating interest rates related to our U.S. Commercial Paper Program (as well as our Revolving Credit Facility and Term Loan, to the extent either are drawn upon in the future) have increased substantially over this same period, a trend that could continue into 2024 and potentially beyond. To the extent that interest rates related to this floating rate debt increase further and the Company borrows under any of these floating interest rate instruments in the future, interest expense and interest payments would increase. There can be no assurance that interest rates will not change significantly from current levels.

RISKS RELATED TO LEGAL AND REGULATORY MATTERS

Our business and financial results may be adversely affected by government contracting risks.

We are subject to various laws and regulations applicable to parties doing business with the U.S. and other governments, including laws and regulations governing reporting obligations, interactions with government officials, performance of government contracts, the use and treatment of government furnished property and the nature of materials used in our products. We may be unilaterally suspended or barred from conducting business with the U.S. and other foreign governments or their suppliers (both directly and indirectly) or become subject to fines or other sanctions if we are found to have violated such laws or regulations. As a result of the need to comply with these laws and regulations, we are subject to increased risks of governmental investigations, civil fraud actions, criminal prosecutions, whistleblower lawsuits and other enforcement actions. For example, the Company reached an agreement in August 2023 with the U.S. government related to an investigation of alleged violations by the Company of the civil False Claims Act. Although the Company did not admit to any liability under the terms of the settlement agreement, the Company agreed to pay the U.S. government a settlement amount, ending the government’s investigation and releasing the Company from further liability for the issues under investigation. The U.S. laws and regulations to which we are subject include, but are not limited to, the Export Administration Regulations, the Federal Acquisition Regulation, the False Claims Act, International Traffic in Arms Regulations, regulations from the Bureau of Alcohol, Tobacco and Firearms and the FCPA. Moreover, we are subject to a wide range of similar laws and regulations in other countries throughout the world. Failure, or the perceived failure, to comply with applicable requirements also could harm our reputation and our ability to compete for future government contracts or sell commercial equivalent products. Any of these outcomes could have a material adverse effect on our business, operations, financial condition, liquidity, and results of operations.

18

Table of Contents

In addition, U.S. government contracts are subject to modification, curtailment or termination by the U.S. government without prior written notice, either for convenience or for default as a result of our failure to perform under the applicable contract. If our contracts are terminated by the U.S. government as a result of our default, we could be liable for additional costs the U.S. government incurs in acquiring undelivered goods or services from another source and any other damages it suffers. Furthermore, the U.S. government periodically audits our governmental contract costs, which could result in fines, penalties or adjustment of costs and prices under the contracts. Any such fines, penalties or payment adjustments resulting from such audits could adversely affect our reputation, business, operations, financial condition, liquidity, and results of operations.

The Company must comply with complex U.S. governmental export and import controls as well as economic sanctions and trade embargoes.

Certain of our products, including purchased components of such products, are subject to U.S. and non-U.S. export control laws and regulations, and may be exported only with the required export license or through an export license exception. In addition, we are required to comply with certain U.S. and non-U.S. economic sanctions and trade embargoes that restrict our ability to transact or deal with certain persons, countries, regions, and governments. These laws and regulations are complex, may change frequently and with limited notice, have generally become more stringent over time and have intensified under recent U.S. administrations, especially in light of ongoing tensions between the U.S. and China. For example, in 2019, the U.S. government added certain of the Company’s customers based in China to the “Entity List” maintained by the U.S. Department of Commerce, which imposes additional restrictions on sales to such customers. Further, in 2022, the U.S. Commerce Department’s Bureau of Industry Security released new export control regulations that restrict the provision to China of certain technology, software, manufacturing equipment and commodities that are used to make certain advanced computing integrated circuits (“ICs”) and supercomputers. These changes include new restrictions on the ability of U.S. companies to provide certain services to any facility in China that manufactures certain advanced ICs. Although, to date, none of such restrictions have had a material adverse effect on the Company’s business, financial condition and results of operations, the U.S. government has the power to place even greater restrictions, and such restrictions could further limit or prohibit the Company from selling its products or providing its services. In addition, we cannot ensure that our policies and procedures designed to maintain compliance with applicable rules and regulations will be effective in preventing instances of non-compliance. If we were to fail to comply with applicable export control restrictions (for example, by failing to obtain required export licensing), customs regulations, economic sanctions and other laws, we could be subject to substantial civil and criminal penalties, including fines, the incarceration of responsible employees and managers, reputational harm, and the possible loss of export or import privileges. In addition, if our distributors fail to obtain appropriate import, export or re-export licenses or permits, we may also be adversely affected through reputational harm and penalties. Obtaining the necessary export license for a particular sale may be time-consuming and may result in the delay or loss of sales opportunities.

Changes in fiscal and tax policies, audits and examinations by taxing authorities could impact the Company’s results.

The Company is subject to tax in the U.S. and in numerous foreign jurisdictions. The Company is currently under tax examination in several jurisdictions, and, in addition, new examinations could be initiated by additional tax authorities. As the Company has operations in jurisdictions throughout the world, the risk of tax examinations will continue to occur. The Company’s financial condition, results of operations or cash flows may be materially impacted by the results of these tax examinations.

On August 16, 2022, the President of the United States signed into law the Inflation Reduction Act of 2022 (the “IRA”), a tax and spending package that introduces several tax-related provisions, including a 15% corporate alternative minimum tax (“CAMT”) on certain large corporations and a 1% excise tax on certain corporate stock repurchases. Companies will be required to reassess their valuation allowances for certain affected deferred tax assets in the period of enactment but will not need to remeasure deferred tax balances for the related tax accounting implications of the CAMT. The IRA provisions, which became effective for Amphenol beginning on January 1, 2023, did not have a material impact on the Company during the year ended December 31, 2023. However, the full impact of these provisions in the future depends on several factors, including interpretive regulatory guidance, which has not yet been released.

The Organization for Economic Co-operation and Development (OECD)/G20 Inclusive Framework, known as Pillar Two, provides guidance for a global minimum tax. This guidance lays out a common approach for adopting the global minimum tax and enacting local legislation codifying the provisions that all 142 countries in the Inclusive Framework agreed to by consensus. The EU member states have agreed to adopt these rules in two stages with the first component effective on January 1, 2024, while the second component will be effective January 1, 2025. Non-EU

19

Table of Contents

countries have enacted or are expected to enact legislation on a similar timeline. Certain countries in which we operate have already enacted legislation to adopt the Pillar Two framework, while several other countries are expected to also implement similar legislation with varying effective dates in the future. When and how this framework is adopted or enacted by the various countries in which we do business will increase tax complexity and may increase uncertainty and adversely affect our provision for income taxes in the U.S. and non-U.S. jurisdictions.

Any future changes in tax laws, regulations, accounting standards for income taxes and/or other tax guidance, including related interpretations associated with the IRA or otherwise, could materially impact the Company’s current and non-current tax liabilities, along with deferred tax assets and liabilities, and consequently, our financial condition, results of operations or cash flows.

We may experience difficulties in enforcing our intellectual property rights, which could result in loss of market share, and we may be subject to claims of infringement of the intellectual property rights of others.

We rely on patent and trade secret laws, copyright, trademark, confidentiality procedures, controls and contractual commitments to protect our intellectual property rights. Despite our efforts, these protections may be limited and, from time to time, we encounter difficulties in protecting our intellectual property rights, particularly in certain countries outside the U.S. We cannot provide assurance that the patents that we hold or may obtain will provide meaningful protection against our competitors. Changes in laws concerning intellectual property, or the enforcement of such laws, may affect our ability to prevent or address the misappropriation of, or the unauthorized use of, our intellectual property, potentially resulting in loss of market share. Litigation may be necessary to enforce our intellectual property rights. Litigation is inherently uncertain and outcomes are unpredictable. If we cannot protect our intellectual property rights against unauthorized copying or use, or other misappropriation, we may not remain competitive.

The intellectual property rights of others could inhibit our ability to introduce new products. Other companies hold patents on technologies used in our industries and are aggressively seeking to expand, enforce and license their patent portfolios. We periodically receive notices from, or have lawsuits filed against us by, third parties claiming infringement, misappropriation or other misuse of their intellectual property rights and/or breach of our agreements with them. These third parties may include entities that do not have the capabilities to design, manufacture, or distribute products or that acquire intellectual property like patents for the sole purpose of monetizing their acquired intellectual property through asserting claims of infringement and misuse. In addition, some foreign competitors may take advantage of the intellectual property laws in their home countries and the more favorable litigation and regulatory environment to our detriment. Third-party claims of infringement may result in loss of revenue, substantial costs or lead to monetary damages or injunctive relief against us.

The Company is subject to customer claims, litigation and other regulatory or legal proceedings.

The Company is currently engaged in, or subject to, various customer claims, litigation and other regulatory and legal matters and may be subject to additional claims, litigation and other regulatory or legal proceedings in the future. Such matters expose the Company to risks that could be material, including, but not limited to, risks related to employment disputes, tax controversies, government investigations, intellectual property infringement, compliance with environmental laws, unfair sales practices, product safety and liability, and product warranty, indemnity and other contract-related claims. These matters may subject the Company to lawsuits, voluntary or forced product recalls, government investigations and criminal liability, including claims for compensatory, punitive or consequential damages, and could result in disruptions to our business and significant legal expenses. These matters could also damage our reputation, harm our relationships with customers or negatively affect product demand.

While the Company does maintain certain insurance coverages that may mitigate losses associated with some of these types of claims and proceedings, the policies may not apply and, where insurance exists, the amount of insurance coverage may not be adequate to cover the total claims and liabilities. In some cases, particularly with respect to product warranty claims from customers, we self-insure against this risk, meaning that any product liability claims will likely have to be paid from Company funds and not by insurance. Any current or future substantial liabilities or regulatory actions could have a material adverse effect on our business, financial condition, cash flows and reputation.

The Company is subject to environmental laws and regulations that could adversely affect our business.

The Company operates in both the United States and various foreign jurisdictions, and we must comply with locally enacted laws and regulations addressing health, safety and environmental matters in such jurisdictions in which we

20

Table of Contents

manufacture and/or sell our products. Certain operations of the Company are subject to locally enacted environmental laws and regulations that govern the discharge of pollutants into the air and water, as well as the handling and disposal of solid and hazardous wastes. The Company and its operations may be subject to liabilities, regardless of fault, for investigative and/or remediation efforts on such matters that may arise at any of the Company’s former or current properties, either owned or leased. Environmental liabilities can result from the use of hazardous materials in production, the disposal of products, damages associated with the use of any of our products or other related matters. We cannot be certain as to the potential impact of any changes to environmental conditions or environmental policies that may arise in any of our jurisdictions. Our failure to comply with these local environmental laws and regulations could result in fines or other punitive damages and/or modifications to our production processes as well as subject us to reputational harm, any of which could adversely impact our financial position, results of operations, or cash flows.

The Company is subject to, and may continue to be subject to, incremental costs, risks and regulations associated with efforts to combat the negative effects of climate change.

There is increased public awareness regarding climate change. This increased focus has led to international treaties and agreements and legislative and regulatory efforts. In addition to the risks discussed under the risk factors titled “The Company may be negatively impacted by extreme weather conditions and natural catastrophic events, including those caused or intensified by climate change and global warming” and “Increasing scrutiny and expectations regarding ESG matters could result in additional costs or risks or otherwise adversely impact our business,” the Company may also be subject to larger, global climate change initiatives, laws, regulations or orders, such as any laws or regulations to implement the Paris Climate Agreement, which seek to reduce greenhouse gas (“GHG”) emissions. In addition to government requirements, our customers are also increasingly imposing climate-related requirements on their suppliers, including us. Any failure, or perceived failure, to comply with these requirements may result in reduced demand for our products, reputational harm, or other adverse impacts to our business.

Given our global manufacturing presence, any future regulations relating to GHG emissions and/or other climate change-related laws and regulations, beyond initiatives already in process at the Company, could subject us to additional and/or unforeseen compliance costs and limitations, increased energy and raw material costs and incremental capital expenditure requirements. In addition, governmental bodies are increasingly adopting and considering adopting additional mandatory climate-related reporting obligations, and potentially GHG emissions reduction requirements, and these regulatory developments, to the extent we are subject to them, will likely result in increased corporate and operational general and administrative efforts and associated costs and expenses.

There have been various new laws around the world that have been passed and will require additional ESG-related disclosure. For example, in Europe, the EU finalized the Corporate Sustainability Reporting Directive (“CSRD”), which introduces more prescriptive sustainability reporting requirements for EU companies as well as certain non-EU companies, and will apply to all in-scope companies by January 1, 2028. In the United States, the SEC has proposed climate-related disclosure rules that have not yet been enacted as of the date of this report, and certain states have begun to pass their own ESG-related laws. For example, on October 7, 2023, the governor of California signed and enacted into law two climate-related disclosure bills (SB-253, Climate Corporate Data Accountability Act and SB-261, Greenhouse Gases: Climate-Related Financial Risk), which will require compliance as early as 2026.

Any future regulatory changes in any of the jurisdictions in which we operate could result in transition risks to the Company, including, but not limited to: (i) the nature and timing of any requirement to lower GHG emissions and adopt more energy-efficient energy use, which could result in changes or disruptions to the way the Company operates, (ii) financial risks where the compliance with such regulations requires unforeseen capital expenditures and becomes costly or financially burdensome, (iii) legal risks associated with the failure to adapt to or comply with future climate change-related regulations, (iv) risks of climate litigation associated with our disclosures and/or operations; (v) risks associated with the implementation of any new technologies required to comply with such regulations, which could impede our ability to develop new products, meet customer and market demand or compete on pricing and quality in the market, and/or (vi) reputational risks associated with our customers’ and investors’ perceptions of the Company and their preferences for maintaining relationships with companies with lower emissions, all of which could harm our reputation in the marketplace.

Item 1C. Cybersecurity

Cybersecurity Risk Management and Strategy

We have developed and implemented an information security and cybersecurity risk management program (“Program”) intended to protect and preserve the confidentiality, integrity and availability of our data and information technology systems. Our Program is integrated into our overall enterprise risk management program. We use the National Institute of Standards and Technology Cybersecurity Framework (the “NIST CSF”) as a benchmark to ensure that our Program is maintained in line with industry best practices. This does not imply that we meet any particular technical standards, specifications or requirements, but it does mean that we use the NIST CSF as a guide to help us identify, assess and manage cybersecurity risks relevant to our business.

The Company maintains a decentralized information technology infrastructure, where each of our business units utilizes a separate and distinct information technology system. This means that if any business unit’s systems are compromised, there is significantly less risk that another business unit will be impacted by that event. This decentralized structure also allows our information security professionals embedded within an individual business unit to make quick, efficient decisions when changes or actions are needed and provides an additional safeguard for our data and systems.

Our Program includes:

risk assessments and penetration tests integrated within our overall risk management processes that are designed to identify cybersecurity and technology risks, as well as to formulate management actions to respond to, mitigate and remediate material issues (if any);
annual management reporting to the Board of Directors (the “Board”);
reporting of the scope, objectives and results of internal audits on the procedures performed on the control environment related to our information security systems and security controls to the Audit Committee at least two times a year;
annual cybersecurity awareness training to instruct employees how to better identify cybersecurity concerns and to avoid actions that might inadvertently allow outsiders to access our systems;
installation of end point protection software on our Company-managed systems and workstations in an effort to detect and prevent malicious code from impacting our systems;
a cross-functional team principally responsible for managing our cybersecurity risk assessment processes and our response to cybersecurity incidents;
the use of external service providers, where appropriate, to assess, monitor, test or otherwise assist with aspects of our security controls and response to cybersecurity incidents; and
a documented framework and supporting processes for handling security incidents that facilitates coordination across multiple parts of the Company.

We have not identified risks from known cybersecurity threats, including as a result of any prior security breach, that have materially affected or are reasonably likely to materially affect us, including our business strategy, financial condition and results of operations. We face certain ongoing risks from cybersecurity threats that, if realized, are reasonably likely to materially affect us, including our operations, business strategy, results of operations or financial condition. For a discussion of certain risks related to cybersecurity, refer to the risk factor titled “Cybersecurity incidents affecting our information technology systems could disrupt business operations or cause the release of highly sensitive confidential or personal information, resulting in adverse impacts to our reputation and operating results and potentially leading to litigation and/or governmental investigations, fines and other penalties” in Part I, Item 1A. Risk Factors herein.

Cybersecurity Governance

Our Board maintains oversight responsibility relating to our Program, with assistance from the Audit Committee. At least annually, our management team (including the leaders of our Information Technology and Internal Audit teams) provides an update regarding our Program to the Board. This update provides an overall assessment of the effectiveness of our Program and a review of areas of focus for the upcoming year. The Board also receives periodic reports from our Vice President, Internal Audit, on the audit focus areas and control testing related to our information security systems

22

Table of Contents

and security controls, and our management team updates the Board, as necessary, regarding any material cybersecurity incidents.

Our management team, including our Senior Vice President and Chief Financial Officer, Senior Vice President and General Counsel, Vice President, Information Technology, and Vice President, Internal Audit, is responsible for assessing and managing our material risks from cybersecurity threats. The team has primary responsibility for our Program and our Vice President, Information Technology, supervises both our internal information security personnel and our retained external cybersecurity consultants. Our management team supervises efforts to prevent, detect, mitigate and remediate cybersecurity risks and incidents through various means, which may include briefings from internal information technology personnel and external consultants engaged by us, as well as alerts and reports produced by security tools deployed in our information technology environment.

Our management team’s experience includes knowledge related to information technology, cybersecurity and incidence response, risk management, control analysis and corporate governance. For additional details about our management team and their experience, refer to the Executive Leadership page on the Company’s website at https://www.amphenol.com/governance/leadership.

Item 2. Properties

The Company’s fixed assets include factories and warehouses and a substantial quantity of machinery and equipment. The Company’s factories, warehouses and machinery and equipment are generally in good operating condition, are reasonably maintained and substantially all of its facilities are in regular use. The Company considers the present level of fixed assets along with planned capital expenditures as suitable and adequate for operations in the current business environment. At December 31, 2023, the Company operated approximately 280 manufacturing facilities with approximately 27 million square feet, of which approximately 19 million square feet were leased. Manufacturing facilities located in the U.S. had approximately 5 million square feet, of which approximately 2 million square feet were leased. Manufacturing facilities located outside the U.S. had approximately 22 million square feet, of which approximately 17 million square feet were leased. The square footage by segment related to our manufacturing facilities was approximately 7 million square feet, 11 million square feet and 9 million square feet for the Harsh Environment Solutions segment, Communications Solutions segment and Interconnect and Sensor Systems segment, respectively.

The Company believes that its facilities are suitable and adequate for its business and are being appropriately utilized for their intended purposes. Utilization of the facilities varies based on demand for the relevant products. The Company regularly reviews its anticipated requirements for facilities and, based on that review, may from time to time acquire or lease additional facilities and/or dispose of existing facilities.

Market Information

The Company effected the initial public offering of its Class A Common Stock (“Common Stock”) in November 1991. The Company’s Common Stock has been listed on the New York Stock Exchange since that time under the ticker symbol “APH”. As of January 31, 2024, there were 31 holders of record of the Company’s Common Stock. A significant number of outstanding shares of Common Stock are registered in the name of only one holder, which is a nominee of The Depository Trust Company, a securities depository for banks and brokerage firms. The Company believes that there are a significant number of beneficial owners of its Common Stock.

Repurchase of Equity Securities

On April 27, 2021, the Board authorized a stock repurchase program under which the Company may purchase up to $2.0 billion of the Company’s Common Stock during the three-year period ending April 27, 2024 (the “2021 Stock Repurchase Program”). During the three months and year ended December 31, 2023, the Company repurchased 1.3 million and 7.2 million shares of its Common Stock for $115.3 million and $585.1 million, respectively, under the 2021 Stock Repurchase Program. Of the total repurchases made in 2023, 5.5 million shares, or $435.8 million, have been retired by the Company, with the remainder of the repurchased shares being retained in Treasury stock at the time of repurchase. From January 1, 2024 through January 31, 2024, the Company did not repurchase any additional shares of its Common Stock, and, as of February 1, 2024, the Company has remaining authorization to purchase up to $226.5 million of its Common Stock under the 2021 Stock Repurchase Program. The timing and amount of any future purchases will depend on a number of factors, such as the levels of cash generation from operations, the volume of stock options exercised by employees, cash requirements for acquisitions, dividends paid, economic and market conditions and the price of the Common Stock.

The Company’s stock repurchases during the three months and year ended December 31, 2023 were as follows:

In 2023, the Company reported net sales and operating income of $12,554.7 and $2,559.6, respectively, each representing a decrease of 1% from 2022, while net income from continuing operations attributable to Amphenol Corporation of $1,928.0 represented an increase of 1% from 2022. In 2023, the Company’s net income from continuing operations attributable to Amphenol Corporation was impacted by (a) excess tax benefits of $82.4 related to stock-based compensation resulting from stock option exercises and (b) the gain of $5.4 on a bargain purchase acquisition that closed in the second quarter of 2023, partially offset by (c) acquisition-related expenses of $34.6 ($30.2 after-tax) comprised primarily of external transaction costs, as well as the amortization of $12.4 related to the value associated with acquired backlog resulting from three of the acquisitions that closed in 2023. In 2022, the Company’s net income from continuing operations attributable to Amphenol Corporation was impacted by (a) excess tax benefits of $56.0 related to stock-based compensation resulting from stock option exercises, partially offset by (b) acquisition-related expenses of $21.5 ($18.4 after-tax) comprised primarily of the amortization related to the value associated with acquired backlog resulting from two acquisitions that closed in 2022, along with external transaction costs. Excluding the effects of these items, Adjusted Operating Income decreased by 1%, while Adjusted Net Income from continuing operations attributable to Amphenol Corporation increased slightly in 2023 compared to 2022. Adjusted Operating Income and Adjusted Net

Income from continuing operations attributable to Amphenol Corporation are both non-GAAP financial measures, each as defined in the “Non-GAAP Financial Measures” section below and reconciled within this Part II, Item 7. Sales and profitability trends are discussed in detail in “Results of Operations” below. In addition, a strength of the Company has been its ability to consistently generate net cash provided by operating activities from continuing operations (“Operating Cash Flow”). The Company uses Operating Cash Flow to fund capital expenditures and acquisitions, repurchase shares of the Company’s Class A Common Stock (“Common Stock”), pay dividends and reduce indebtedness. In 2023, the Company generated Operating Cash Flow of $2,528.7 and Free Cash Flow of $2,159.9, compared to Operating Cash Flow of $2,174.6 and Free Cash Flow of $1,796.4 in 2022. Free Cash Flow, a non-GAAP financial measure, is defined in the “Non-GAAP Financial Measures” section below and reconciled within this Part II, Item 7.

Inflation Reduction Act of 2022

On August 16, 2022, the President of the United States signed into law the Inflation Reduction Act of 2022 (the “IRA”), a tax and spending package that introduces several tax-related provisions, including a 15% corporate alternative minimum tax (“CAMT”) on certain large corporations and a 1% excise tax on certain corporate stock repurchases. Companies will be required to reassess their valuation allowances for certain affected deferred tax assets in the period of enactment but will not need to remeasure deferred tax balances for the related tax accounting implications of the CAMT. The IRA provisions, which became effective for Amphenol beginning on January 1, 2023, did not have a material impact on the Company during the year ended December 31, 2023. While the full impact of these provisions in the future depends on several factors, including interpretive regulatory guidance, which has not yet been released, the Company does not currently believe that the provisions of the IRA, including several other non-tax related provisions, will have a material impact on its financial condition, results of operations, liquidity and cash flows.

Pillar Two Framework

The Organization for Economic Co-operation and Development (OECD)/G20 Inclusive Framework, known as Pillar Two, provides guidance for a global minimum tax. This guidance lays out a common approach for adopting the global minimum tax and enacting local legislation codifying the provisions that all 142 countries in the Inclusive Framework agreed to by consensus. The European Union (“EU”) member states have agreed to adopt these rules in two stages with the first component effective on January 1, 2024, while the second component will be effective January 1, 2025. Non-EU countries have enacted or are expected to enact legislation on a similar timeline. Certain countries in which we operate have already enacted legislation to adopt the Pillar Two framework, while several other countries are expected to also implement similar legislation with varying effective dates in the future. When and how this framework is adopted or enacted by the various countries in which we do business will increase tax complexity and may increase uncertainty and adversely affect our provision for income taxes in the U.S. and non-U.S. jurisdictions. The Company has done a preliminary review of currently enacted legislation and does not expect the initial implementation to materially impact future results. However, the Company will continue to evaluate the potential impact of Pillar Two on the Company and its future results, as additional countries adopt legislation and issue individual guidance on their enacted legislation.

2023 Compared to 2022

Net sales were $12,554.7 for the year ended December 31, 2023 compared to $12,623.0 for the year ended December 31, 2022, which represented a decrease of 1% in U.S. dollars and 3% organically (excluding both currency and acquisition impacts), while flat in constant currencies compared to the prior year. The decrease in net sales in 2023 was driven by a sales decline in the Communications Solutions segment, partially offset by growth in the Harsh Environment Solutions and Interconnect and Sensor Systems segments, as described below. From an end market standpoint, the decrease in net sales was driven by organic declines in the information technology and data communications (“IT datacom”), mobile networks, mobile devices, industrial and broadband communications markets, partially offset by robust organic growth in the automotive, defense and commercial aerospace markets, along with contributions from the Company’s acquisition program. Net sales to the automotive market increased approximately $310.5, reflecting broad-based strength across our global automotive markets, in particular, next-generation electronics, including electric and hybrid drive trains. Net sales to the defense market increased approximately $237.6, driven by broad-based strength across virtually all defense applications, particularly related to naval, aircraft engines, helicopters, communications, and space-related applications, as well as contributions from acquisitions. Net sales to the commercial aerospace market increased approximately $117.9, primarily due to increased broad-based demand across all aircraft applications, in particular larger passenger planes. Net sales to the industrial market remained flat, as contributions from acquisitions, along with growth in medical, oil and gas, mass transit and transportation applications were offset by moderations in industrial instrumentation, battery and electric heavy vehicles, factory automation and heavy equipment applications. Net sales to the IT datacom market decreased approximately $362.8, as we experienced moderations across a broad array of applications including networking equipment, cloud storage, transmission, consumer electronics and servers, partially offset by strong growth in artificial intelligence-related applications. Net sales to the mobile networks market decreased approximately $163.9, driven by broad-based moderations in demand from mobile network operators and wireless equipment manufacturers, partially offset by contributions from acquisitions. Net sales to the mobile devices market decreased approximately $161.5, driven by declines in sales in laptops, wearable devices, tablets and production-related products, partially offset by growth in smartphones. Net sales to the broadband communications market decreased approximately $46.4, driven by moderations in demand from broadband service operators.

Net sales in the Harsh Environment Solutions segment (approximately 28% of net sales) increased 14% in U.S. dollars, 14% in constant currencies and 9% organically, in 2023, compared to 2022. The sales growth in 2023 was primarily driven by strong organic growth in the defense, commercial aerospace, automotive and IT datacom markets, along with contributions from the Company’s acquisition program, partially offset by organic declines in the industrial and mobile networks markets.

Net sales in the Communications Solutions segment (approximately 39% of net sales) decreased 13% in U.S. dollars, 12% in constant currencies and 13% organically, in 2023, compared to 2022. The sales decline in 2023 was primarily driven by organic declines in the IT datacom, industrial, mobile networks, mobile devices and broadband communications markets, partially offset by strong organic growth in the automotive market, along with modest contributions from the Company’s acquisition program.

Net sales in the Interconnect and Sensor Systems segment (approximately 33% of net sales) increased 6% in U.S. dollars, 7% in constant currencies and 3% organically, in 2023, compared to 2022. The sales growth in 2023 was primarily driven by strong organic growth in the automotive and commercial aerospace markets, and moderate growth in the industrial and defense markets, along with contributions from the Company’s acquisition program, partially offset by organic declines in the IT datacom and mobile networks markets.

(1)Percentages in this table were calculated using actual, unrounded results; therefore, the sum of the components may not add due to rounding.
(2)Net sales growth in U.S. dollars is calculated based on Net sales as reported in the Consolidated Statements of Income and Note 13 of the Notes to Consolidated Financial Statements. While the term “net sales growth in U.S. dollars” is not considered a U.S. GAAP financial measure, for purposes of this table, we derive the reported (GAAP) measure based on GAAP results, which serves as the basis for the reconciliation to its comparable non-GAAP financial measures.
(3)Foreign currency translation impact, a non-GAAP measure, represents the percentage impact on net sales resulting from foreign currency exchange rate changes in the current reporting year compared to the prior reporting year. Such amount is calculated by subtracting current year net sales translated at average foreign currency exchange rates for the prior year from current year net sales, taken as a percentage of the prior year’s net sales.
(4)Constant Currency Net Sales Growth and Organic Net Sales Growth are non-GAAP financial measures as defined in the “Non-GAAP Financial Measures” section of this Item 7.
(5)Acquisition impact, a non-GAAP measure, represents the percentage impact on net sales resulting from acquisitions that have not been included in the Company’s consolidated results for the full current year and/or prior comparable year presented. Such net sales related to these acquisitions do not reflect the underlying growth of the Company on a comparative basis. Acquisition impact is calculated as a percentage of the respective prior year period(s) net sales.
(6)Net sales by geographic area are based on the customer location to which the product is shipped.

The decrease in foreign net sales in 2023 compared to 2022 was primarily driven by sales declines in Asia. The comparatively stronger U.S. dollar in 2023 had the effect of decreasing sales by approximately $61.1, compared to 2022.

Selling, general and administrative expenses were $1,489.9, or 11.9% of net sales for 2023, compared to $1,420.9, or 11.3% of net sales, for 2022. The increase in Selling, general and administrative expenses as a percentage of net sales in 2023 was primarily driven by the effect of acquisitions, which currently have higher selling, general and administrative expenses as a percentage of net sales compared to the Company average. Administrative expenses increased $26.2 in 2023 and represented approximately 4.8% of net sales in 2023 and 4.6% of net sales in 2022. Research and development expenses increased $18.6 in 2023, primarily related to increases in expenses for new product development, and represented approximately 2.7% of net sales in 2023 and 2.6% of net sales in 2022. Selling and marketing expenses increased $24.2 in 2023 compared to 2022, and represented approximately 4.3% of net sales in 2023 and 4.1% of net sales in 2022.

Operating income was $2,559.6, or 20.4% of net sales, in 2023, compared to $2,585.8, or 20.5% of net sales, in 2022. Operating income in 2023 included acquisition-related expenses of $34.6, comprised primarily of external transaction costs, as well as the amortization related to the value associated with acquired backlog resulting from three of the acquisitions that closed in 2023. Operating income in 2022 included acquisition-related expenses of $21.5,

comprised primarily of the amortization related to the value associated with acquired backlog resulting from two acquisitions that closed in 2022, along with external transaction costs. The acquisition-related expenses in 2023 and 2022 had the effect of decreasing net income from continuing operations by $30.2, or $0.05 per share, and $18.4, or $0.03 per share, respectively. Acquisition-related expenses are presented separately in the Consolidated Statements of Income. Excluding the effect of these acquisition-related expenses, Adjusted Operating Income and Adjusted Operating Margin, each as defined in the “Non-GAAP Financial Measures” section below, were $2,594.2 and 20.7% of net sales, respectively, in 2023, and $2,607.3 and 20.7% of net sales, respectively, in 2022. While Adjusted Operating Income decreased modestly from 2022, Adjusted Operating Margin remained flat in 2023 relative to 2022, as the benefit of pricing actions and strong operational performance were offset by the operating leverage on the lower sales volumes, along with the negative impact on operating margin related to acquisitions that are currently operating below the average operating margin of the Company.

Operating income for the Harsh Environment Solutions segment in 2023 was $943.9, or 26.7% of net sales, compared to $801.6, or 25.8% of net sales in 2022. The increase in operating margin for the Harsh Environment Solutions segment for 2023 compared to 2022 was primarily driven by normal operating leverage on the higher sales volumes and strong operational performance, combined with the benefit of pricing actions, all partially offset by the negative impact on operating margin related to acquisitions that are currently operating below the average operating margin of the Company.
